Integration of a mobile autonomous robot in a surveillance multi-agent system

This dissertation aims to guarantee the integration of a mobile autonomous robot equipped with many sensors in a multi-agent distributed and georeferenced surveillance system. The integration of a mobile autonomous robot in this system leads to new features that will be available to clients of surveillance system may use. These features may be of two types: using the robot as an agent that will act in the environment or by using the robot as a mobile set of sensors. As an agent in the system, the robot can move to certain locations when alerts are received, in order to acknowledge the underlying events or take to action in order to assist in resolving this event. As a sensor platform in the system, it is possible to access information that is read from the sensors of the robot and access complementary measurements to the ones taken by other sensors in the multi-agent system. To integrate this mobile robot in an effective way it is necessary to extend the current multi-agent system architecture to make the connection between the two systems and to integrate the functionalities provided by the robot into the multi-agent system.

A lesão de isquémia/reperfusão em transplante hepático: análise genética, morfológica e correlação clínica

RESUMO: O transplante hepático ortotópico é uma terapêutica aceite para casos selecionados de falência hepática terminal. O procedimento tem-­‐se aperfeiçoado, evidenciado pelo aumento da taxa de sobrevida de 30 para 75% aos 5 anos, mas cerca de 13 a 27% dos enxertos desenvolve falência primária (PNF) ou disfunção primária (DF) após o transplante. As consequências são devastadoras para a sobrevida do doente e do enxerto. A sua etiologia é multifactorial, incluindo factores relacionados com o dador e o receptor, tempos de isquémia, agressões cirúrgicas, bem como características anatomopatológicas do enxerto. A lesão de isquémia/reperfusão mantem-­‐se como um factor de risco intra operatório, com implicações directas sobre toda a evolução do transplante : existe uma relação íntima entre a PNF e a DF, a preservação do enxerto, a lesão de isquémia/reperfusão, e a falência do transplante. Além disso, está comprovada evidência que sugere que a lesão de I/R torna um aloenxerto mais vulnerável por aumento da imunogenicidade, aumentando a probabilidade de episódios de rejeição precoce e tardia. Com base na prática clínica quotidiana do CHBPT HCC, estudaram-­‐se 54 casos de transplante hepático, agrupados segundo grupos por alocação do enxerto respectivo: Grupo 1(n=27): dador cadáver para receptor cirrótico, Grupo 2 (n=15): dador cadáver para receptor PAF, Grupo 3 (n=12): dador PAF para receptor cirrótico. Observaram-­‐se as alterações histológicas e moleculares sobre o enxerto até ao final da operação do receptor, e as suas consequências clínicas,avaliando: -­‐ As diferentes capacidades de resistência e cada enxerto à lesão de isquémia/reperfusão. -­‐ As situações em que os factores do receptor se sobrepõem às do enxerto na definição do prognóstico, e vice versa. -­‐ A relevância das lesões histológicas e moleculares precoces no tecido hepático na evolução do enxerto e do receptor. Foram colhidas biópsias por agulha dos 54 enxertos hepáticos,42 provenientes de cadáver com coração batente(morte cerebral) e 12 provenientes de dador vivo com PAF, em três tempos diferentes do processo de colheita e transplante hepático: ­‐ A primeira(T0)antes da clampagem da aorta do dador -­‐ A segunda (T1) no final da isquémia fria -­‐ A terceira (T2) após a reperfusão do enxerto, durante o encerramento da parede abdominal. A estas amostras foi extraído RNA total, convertido em cDNA por transcrição reversa e feita a análise da expressão dos genes da CTLA4, IL-­‐1β, IL-­‐4, IL-­‐6, IL-­‐13, TNF-­‐α, Perforina, Selectina, (SELE), Fas-­‐ligando, Granzima-­‐B, Heme-­‐Oxigenase 1(HO1)e Óxido Nítrico Sintetase(iNOS2A)por PCR quantitativo segundo o método do Ct comparativo, utilizando como referência a expressão dos genes da amostra não-­‐isquémica –T0. Os fragmentos de todas as biópsias foram seccionados, para envio de amostra comparativa para processamento histológico habitual, sem qualquer alteração ao protocolo seguido habitualmente na Unidade de Transplantação do Hospital Curry Cabral. A presença de alguns parâmetros histológicos definidos, como esteatose, necrose, vacuolização, congestão sinusoidal e infiltração neutrofílica, foi registada e contabilizada numa classificação numérica. O seguimento clínico e laboratorial, bem como o acompanhamento de eventuais complicações, foi registado e correlacionado com os dados das colheitas de órgãos e com os dados das biópsias. Foram consideradas as seguintes variáveis, como as mais relevantes e objectivas para a interpretação da evolução clínica, tendo sido comparadas estatisticamente com os dados recolhidos, laboratoriais e clínicos: disfunção do enxerto, 207 pós operatórias, número de internamentos igual ou superior a 2 e rejeição crónica e/ou morte do receptor. Foram identificadas características clínicas menos favoráveis, a considerar, nalgumas circunstâncias: género feminino do receptor (sobretudo associado a enxerto masculino, p=0,077), isquémia fria superior a 500 minutos (p=0,074), isquémia quente superior a 90 minutos (p=0,099). Na análise laboratorial, distinguiram-­‐se duas características histológicas desfavoráveis e irreversíveis, como índice de mau prognóstico: a necrose e a balonização (p=0,029); no painel genético escolhido neste estudo,a expressão basal de IL-­‐1β(p=0,028), de SELE p=0,013)e de FAS-­‐L (p=0,079)relacionaram-­‐se com pior prognóstico. Algumas características protectoras intrínsecas dos enxertos só se revelaram indirectamente, como menor infiltração neutrofílica e maior expressão de HO1 e de iNOS nos enxertos PAF, não tendo sido possível provar uma interferência directa nos resultados clínicos. Não se obteve expressão mensurável de genes anti-­‐ inflamatórios nas biopsias hepáticas processadas neste estudo, como a IL13 e a I 4: assim, com a metodologia utilizada, não foi possível obter um perfil de expressão genética associado a boa evolução clínica. O perfil inverso foi sugerido apenas pela expressão basal dos 3 genes mencionados (FAS-­‐L,IL-­‐1β e SELE)no mesmo painel, com o protocolo seguido neste conjunto de 54 doentes. As características do receptor sobrepuseram-­‐se às do enxerto no caso de: -­‐ diagnóstico de PAF no receptor, que determinou uma maior predisposição para a disfunção do enxerto, o que, por sua vez, determina uma menor sobrevida. No entanto, o diagnóstico de PAF no receptor exibe uma curva de sobrevida mais favorável. -­‐ receptores com um baixo balanço de risco (BAR)definiram características favoráveis para enxertos com níveis baixos e moderados de esteatose, fazendo que esta característica, definida como um risco acrescido, não só não se manifestasse clinicamente,como parecesse um factor favorável. As características do enxerto sobrepuseram-­‐se às do receptor no caso de: -­‐ tempo de isquémia fria superior a 500 minutos -­‐ balonização, necrose, FAS-­‐L,IL-­‐1β e SELE em T0 A integração dos resultados moleculares e morfológicos com a evolução clínica, realça o papel da mobilização precoce de neutrófilos nos desempenhos menos favoráveis do enxerto hepático. -------------ABSTRACT: Orthotopic liver transplantation is na accepted therapeutic procedure for selected cases of terminal liver failure. The procedure has been improved, evidenced by the rise of survival rates from 30 to 70% at 5 years, but 13 to 27% of the liver grafts develops primary non function (PNF) or primary dysfunction (PDF) after transplantation. The consequences are devastating for the survival of the patient and of the graft. Its etiology is multifactorial, including factos related with the donor and with the recipient, ischemic times, surgical aggressions, as well as the histological characteristics of the graft. The ischemia/reperfusion lesion is still an intraoperative risk factor, with direct implications in the whole transplant outcome: there is a close interrelation between PNF and DF, graft preservation, ischemia / reperfusion lesion and graft failure. Beyond his, there is proved evidence that suggests that I/R lesion turns the allograft more vulnerable by increasing its immunogenity, increasing the probability of precocious and late rejection episodes. Based on the daily clinical practice at CHBPT /HCC, 54 cases of hepatic transplantation have been studied, grouped by allocation of each graft: Group (n=27):deceased do nortocirrhotic recipient, Group 2 (n=15): deceased donor to FAP recipient, Group 3 (n=12): FAP living donor to cirrhotic recipient. The histologic and molecular changes in the liver graft were observed until the end of the recipiente operation,together with its clinical consequences, evaluating:-­‐The different capacity of resistance of each graft to the ischemia / reperfusion lesion -­‐ The situations where the recipiente factos overlap the ones of the graft, in the definition of prognosis, and vice versa.-­‐ The relevance of the precocious histologic and molecular lesions of the hepatic tissue in the clinical outcome of the graft and the recipient. Needle biopsies were obtained from 54 liver grafts, 42 deceased brain dead donors and 12 from FAP living donors, at three diferente times of the harvesting and the hepatic transplantation: The first one (T0) before clamping the donor aorta -­‐ The second one (T2) in the end of cold ischemia time -­‐ The third one (T) after the reperfusion of the graft, during the closure of the abdominal wall. Total RNAwas extracted to these samples, converted to cDNA by reverse transcription and the analysis of gene expression was made for CTLA4,IL-­‐1β,IL-­‐4,IL-­‐6,IL-­‐13,TNF-­‐α,Perforin,E Selectin (SELE),Fas-­‐ligand,Granzyme-­‐B,Heme-­‐oxigenase 1 (HO1) and Nitric Oxide Sintetase (iNOS2A) by quantitative PCR, according with the Ct comparative method, using the expression of the non ischemic sample – T0. The fragments of all the biopsies were divided, to send a comparative sample to the usual histologic processement, keeping the same usual protocol at the Transplantation Unit of Curry Cabral Hospital. The presence of some defined histologic parameters, such as steatosis, necrosis, vacuolization, sinusoidal congestion and neutrophilic infiltration, was registered and catalogued in a numeric classification. The clinical and laboratory follow-­‐up, as well as the following of eventual complications, was registered and correlated with the data from organ procurement operations and with the data from the biopsies. The following variables were considered as the most relevant and objective ones, to the interpretation of the clinical evolution, being statistically compared with the clinical and laboratorial collected data: graft dysfunction, post-­‐operative complications, number of readmissions of 2 or more and chronic rejection and /or recipiente death. There were identified some unfavorable clinical characteristics, to be considered under certain circumstances: recipiente female gender (specially associated with malegraft, p=0,077), cold ischemia time of more than 500 minutes (p=0,074), warm ischemia time of more than 90 minutes (p=0,099). In the laboratory analysis, two histologic characteristics were identified as unfavorable and irreversible, associated with bad prognosis: necrosis and balonization (p=0,029); in the gene panel selected in this study, the basal expression of IL-­‐1β (p=0,028), SELE (p=0,013) and FAS-­‐L (p=0,079)were related with worse prognosis.Some intrinsic protective characteristics of the grafts were only indirectly revealed, such as less neutrophilic infiltration and bigger expression of HO1 and iNOS in FAP grafts, being impossible to prove any direct inte ference in the clinical results. A relevant and measurable expression of the anti inflammatory genes IL13 and IL4 was not obtained: with the used methodology, it was impossible to obtain a gene expression profile associated with a favorable clinical outcome.The inverse profile was suggested only by the basal expression of the three mentioned genes (FAS-­‐L, IL-­‐ 1β e SELE) in the same gene panel, according with the followed protocol in this group of 54 patients. The characteristics of the recipient overlapped those from the graft, in the case of :-­‐ FAP diagnosis in the recipient, which determined a bigger predisposition to graft dysfunction, which by itself determines a shorter survival. However, FAP diagnosis in the recipiente depicts a more favorable survival curve. -­‐ Recipients with a low balance risk índex (BAR) defined favorable characteristics to grafts with low and moderate grades of steatosis, making that this characteristic, associated with bad prognosis, looked like a favorable factor, and with no clinical interference. The graft characteristics overlapped those from the receptor in the case of: -­‐ Cold ischemic time more than 500 minutes -­‐ Balonization, necrosis, FAS-­‐L, IL-­‐1β and SELE at T0. The integration of molecular and morphologic results with the clinical evolution, stresses the role of a precocious neutrophils mobilization in the worse outcomes of liver grafts.

Assessment of integration of the leprosy program into primary health care in Aracaju, state of Sergipe, Brazil

INTRODUCTION: The aim of this study was to assess the epidemiological and operational characteristics of the Leprosy Program before and after its integration into the Primary healthcare Services of the municipality of Aracaju-Sergipe, Brazil. METHODS: Data were drawn from the national database. The study periods were divided into preintegration (1996-2000) and postintegration (2001-2007). Annual rates of epidemiological detection were calculated. Frequency data on clinico-epidemiological variables of cases detected and treated for the two periods were compared using the Chi-squared (χ2) test adopting a 5% level of significance. RESULTS: Rates of detection overall, and in subjects younger than 15 years, were greater for the postintegration period and were higher than rates recorded for Brazil as a whole during the same periods. A total of 780 and 1,469 cases were registered during the preintegration and postintegration periods, respectively. Observations for the postintegration period were as follows: I) a higher proportion of cases with disability grade assessed at diagnosis, with increase of 60.9% to 78.8% (p < 0.001), and at end of treatment, from 41.4% to 44.4% (p < 0.023); II) an increase in proportion of cases detected by contact examination, from 2.1% to 4.1% (p < 0.001); and III) a lower level of treatment default with a decrease from 5.64 to 3.35 (p < 0.008). Only 34% of cases registered from 2001 to 2007 were examined. CONCLUSIONS: The shift observed in rates of detection overall, and in subjects younger than 15 years, during the postintegration period indicate an increased level of health care access. The fall in number of patients abandoning treatment indicates greater adherence to treatment. However, previous shortcomings in key actions, pivotal to attaining the outcomes and impact envisaged for the program, persisted in the postintegration period.

Simplified wind turbine models for wind energy integration into power systems

This paper analyses the boundaries of simplified wind turbine models used to represent the behavior of wind turbines in order to conduct power system stability studies. Based on experimental measurements, the response of recent simplified (also known as generic) wind turbine models that are currently being developed by the International Standard IEC 61400-27 is compared to complex detailed models elaborated by wind turbine manufacturers. This International Standard, whose Technical Committee was convened in October 2009, is focused on defining generic simulation models for both wind turbines (Part 1) and wind farms (Part 2). The results of this work provide an improved understanding of the usability of generic models for conducting power system simulations.

Barriers preventing the successful integration of mental health services into Primary Health Care in Nigeria : a mixed methods approach

RESUMO: A Nigéria tem uma população estimada em cerca de 170 milhões de pessoas. O número de profissionais de saúde mental é muito diminuto, contando apenas com 150 psiquiatras o que perfaz aproximadamente um rácio de psiquiatra: população de mais de 1:1 milhão de pessoas. O Plano Nacional de Saúde Mental de 1991 reconheceu esta insuficiência e recomendou a integração dos serviços de saúde mental nos cuidados de saúde primários (CSP). Depois de mais de duas décadas, essa política não foi ainda implementada. Este estudo teve como objetivos mapear a estrutura organizacional dos serviços de saúde mental da Nigéria, e explorar os desafios e barreiras que impedem a integração bem-sucedida dos serviços de saúde mental nos cuidados de saúde primários, isto segundo a perspectiva dos profissionais dos cuidados de saúde primários. Com este objetivo, desenvolveu-se um estudo exploratório sequencial e utilizou-se um modelo misto para a recolha de dados. A aplicação em simultâneo de abordagens qualitativas e quantitativas permitiram compreender os problemas relacionados com a integração dos serviços de saúde mental nos CSP na Nigéria. No estudo qualitativo inicial, foram realizadas entrevistas com listagens abertas a 30 profissionais dos CSP, seguidas de dois grupos focais com profissionais dos CSP de duas zonas governamentais do estado de Oyo de forma a obter uma visão global das perspectivas destes profissionais locais sobre os desafios e barreiras que impedem uma integração bem-sucedida dos serviços de saúde mental nos CSP. Subsequentemente, foram realizadas entrevistas com quatro pessoas-chave, especificamente coordenadores e especialistas em saúde mental. Os resultados do estudo qualitativo foram utilizados para desenvolver um questionário para análise quantitativa das opiniões de uma amostra maior e mais representativa dos profissionais dos CSP do Estado de Oyo, bem como de duas zonas governamentais locais do Estado de Osun. As barreiras mais comummente identificadas a partir deste estudo incluem o estigma e os preconceitos sobre a doença mental, a formação inadequada dos profissionais dos CPS sobre saúde mental, a perceção pela equipa dos CSP de baixa prioridade de ação do Governo, o medo da agressão e violência pela equipa dos CSP, bem como a falta de disponibilidade de fármacos. As recomendações para superar estes desafios incluem a melhoria sustentada dos esforços da advocacia à saúde mental que vise uma maior valorização e apoio governamental, a formação e treino organizados dos profissionais dos cuidados primários, a criação de redes de referência e de apoio com instituições terciárias adjacentes, e o engajamento da comunidade para melhorar o acesso aos serviços e à reabilitação, pelas pessoas com doença mental. Estes resultados fornecem indicações úteis sobre a perceção das barreiras para a integração bem sucedida dos serviços de saúde mental nos CSP, enquanto se recomenda uma abordagem holística e abrangente. Esta informação pode orientar as futuras tentativas de implementação da integração dos serviços de saúde mental nos cuidados primários na Nigéria.------------ABSTRACT: Nigeria has an estimated population of about 170 million people but the number of mental health professionals is very small, with about 150 psychiatrists. This roughly translates to a psychiatrist:population ratio of more than 1:1 million people. The National Mental Health Policy of 1991 recognized this deficiency and recommended the integration of mental health into primary health care (PHC) delivery system. After more than two decades, this policy has yet to be implemented. This study aimed to map out the organizational structure of the mental health systems in Nigeria, and to explore the challenges and barriers preventing the successful integration of mental health into primary health care, from the perspective of the primary health care workers. A mixed methods exploratory sequential study design was employed, which entails the use of sequential timing in the combined methods of data collection. A combination of qualitative and uantitative approaches in sequence, were utilized to understand the problems of mental health services integration into PHC in Nigeria. The initial qualitative phase utilized free listing interviews with 30 PHC workers, followed by two focus group discussions with primary care workers from two Local Government Areas (LGA) of Oyo State to gain useful insight into the local perspectives of PHC workers about the challenges and barriers preventing successful integration of mental health care services into PHC. Subsequently, 4 key informant interviews with PHC co-ordinators and mental health experts were carried out. The findings from the qualitative study were utilized to develop a quantitative study questionnaire to understand the opinions of a larger and more representative sample of PHC staff in two more LGAs of Oyo State, as well as 2 LGAs from Osun State. The common barriers identified from this study include stigma and misconceptions about mental illness, inadequate training of PHC staff about mental health, low government priority, fear of aggression and violence by the PHC staff, as well as non-availability of medications. Recommendations for overcoming these challenges include improved and sustained efforts at mental health advocacy to gain governmental attention and support, organized training and retraining for primary care staff, establishment of referral and supportive networks with neighbouring tertiary facilities and community engagement to improve service utilization and rehabilitation of mentally ill persons. These findings provide useful insight into the barriers to the successful integration of mental health into PHC, while recommending a holistic and comprehensive approach. This information can guide future attempts to implement the integration of mental health into primary care in Nigeria.

Integration of speech-processing technologies into Activobank's client interaction process

This dissertation analyzes the possibilities of utilizing speech-processing technologies to transform the user experience of ActivoBank’s customers while using remote banking solutions. The technologies are examined through different criteria to determine if they support the bank’s goals and strategy and whether they should be incorporated in the bank’s offering. These criteria include the alignment with ActivoBank’s values, the suitability of the technology providers, the benefits these technologies entail, potential risks, appeal to the customers and impact on customer satisfaction. The analysis suggests that ActivoBank might not be in a position to adopt these technologies at this point in time.

Analysis of the detection coefficient for the association between leprosy and pregnancy in the integration region of Carajas, State of Para, Brazil

Introduction The association between leprosy and pregnancy is currently poorly understood and has been linked to serious clinical consequences. Methods A retrospective study between 2007 and 2009 was performed in the integration region of Carajás, Brazil on a population of pregnant lepers, with non-lepers of ages 12-49 years serving as the reference population. Results Twenty-nine pregnant lepers were studied during the study period. The detection rates (DRs) for the studied association were 4.7 in 2007, 9.4 in 2008, and 4.3 in 2009. Conclusions The Carajás region presented a medium pattern of endemicity during most of the study period, with a high DR found in 2008.

The integration of online advertising into social media

This study examined user-generated (UG) advertising in the context of social media networks. The focus was on how people, whether an expert in the area, a non-expert or a friend, influence the reader of the advertisement. Furthermore, the study analyzed how the certainty level of the UG advertisement influences the person viewing the ad. The study showed that for the friend source a high certainty message was more persuasive. However, regarding the certainty no significant results were found for the expert and non-expert. Further, the type of the source had a considerable impact on persuasion. Someone that we personally know (e.g., a friend) was rated most positive for all analyzes variables. This shows that with the rising usage of social media there are great opportunities for new effective advertising strategies that could include a new type of an endorser – friends.

Electro-Optical/Infrared sensor turret integration on an aircraft - structural im-pact on LOCKHEED MARTIN C-130H and design methodology

The growing need to patrol and survey large maritime and terrestrial areas increased the need to integrate external sensors on aircraft in order to accomplish those patrols at increasingly higher altitudes, longer range and not depending upon vehicle type. The main focus of this work is to elaborate a practical, simple, effective and efficient methodology for the aircraft modification procedure resulting from the integration of an Elec-tro-Optical/Infra-Red (EO/IR) turret through a support structure. The importance of the devel-opment of a good methodology relies on the correct management of project variables as time, available resources and project complexity. The key is to deliver a proper tool for a project de-sign team that will be used to create a solution that fulfils all technical, non-technical and certi-fication requirements present in this field of transportation. The created methodology is inde-pendent of two main inputs: sensor model and aircraft model definition, and therefore it is in-tended to deliver the results for different projects besides the one that was presented in this work as a case study. This particular case study presents the development of a structure support for FLIR STAR SAPHIRE III turret integration on the front lower fuselage bulkhead (radome) of the LOCKHEED MARTIN C-130 H. Development of the case study focuses on the study of local structural analysis through the use of Finite Element Method (FEM). Development of this Dissertation resulted in a cooperation between Faculty of Science and Technology - Universidade Nova de Lisboa and the company OGMA - Indústria Aeronáutica de Portugal

Integration of geometric consistency contributory factors in three-leg junctions collision prediction models of Portuguese two-lane national highways

This paper aims at developing a collision prediction model for three-leg junctions located in national roads (NR) in Northern Portugal. The focus is to identify factors that contribute for collision type crashes in those locations, mainly factors related to road geometric consistency, since literature is scarce on those, and to research the impact of three modeling methods: generalized estimating equations, random-effects negative binomial models and random-parameters negative binomial models, on the factors of those models. The database used included data published between 2008 and 2010 of 177 three-leg junctions. It was split in three groups of contributing factors which were tested sequentially for each of the adopted models: at first only traffic, then, traffic and the geometric characteristics of the junctions within their area of influence; and, lastly, factors which show the difference between the geometric characteristics of the segments boarding the junctionsâ area of influence and the segment included in that area were added. The choice of the best modeling technique was supported by the result of a cross validation made to ascertain the best model for the three sets of researched contributing factors. The models fitted with random-parameters negative binomial models had the best performance in the process. In the best models obtained for every modeling technique, the characteristics of the road environment, including proxy measures for the geometric consistency, along with traffic volume, contribute significantly to the number of collisions. Both the variables concerning junctions and the various national highway segments in their area of influence, as well as variations from those characteristics concerning roadway segments which border the already mentioned area of influence have proven their relevance and, therefore, there is a rightful need to incorporate the effect of geometric consistency in the three-leg junctions safety studies.

Reconstructing transcriptional regulatory networks using data integration and text mining

Transcriptional Regulatory Networks (TRNs) are powerful tool for representing several interactions that occur within a cell. Recent studies have provided information to help researchers in the tasks of building and understanding these networks. One of the major sources of information to build TRNs is biomedical literature. However, due to the rapidly increasing number of scientific papers, it is quite difficult to analyse the large amount of papers that have been published about this subject. This fact has heightened the importance of Biomedical Text Mining approaches in this task. Also, owing to the lack of adequate standards, as the number of databases increases, several inconsistencies concerning gene and protein names and identifiers are common. In this work, we developed an integrated approach for the reconstruction of TRNs that retrieve the relevant information from important biological databases and insert it into a unique repository, named KREN. Also, we applied text mining techniques over this integrated repository to build TRNs. However, was necessary to create a dictionary of names and synonyms associated with these entities and also develop an approach that retrieves all the abstracts from the related scientific papers stored on PubMed, in order to create a corpora of data about genes. Furthermore, these tasks were integrated into @Note, a software system that allows to use some methods from the Biomedical Text Mining field, including an algorithms for Named Entity Recognition (NER), extraction of all relevant terms from publication abstracts, extraction relationships between biological entities (genes, proteins and transcription factors). And finally, extended this tool to allow the reconstruction Transcriptional Regulatory Networks through using scientific literature.

Low f-number microlenses for integration on optical microsystems

This paper presents microlenses (MLs) with low f-number made of AZ4562 photoresist for integration on optical microsystems. The fabrication process was based on the thermal reflow and rehydration. Large series of MLs were fabricated with a width of 35 μm, a thickness of 5 μm, and spaced apart by 3 μm. The MLs were fabricated directly on the surface of a die with type n+/p-substrate junction photodiode fabricated in a standard CMOS process. The measured focal length was 49 μm with a tolerance of ±2 μm (maximum error of ±4%), resulting in a numerical aperture of 33.6 × 10-2 (±1.3 × 10-2). The measurements also revealed an f-number of 1.4.
