Prognostic value of cortically induced motor evoked activity by TMS in chronic stroke: caveats from a very revealing single clinical case

Background: We report the case of a chronic stroke patient (62 months after injury) showing total absence of motor activity evoked by transcranial magnetic stimulation (TMS) of spared regions of the left motor cortex, but near-to-complete recovery of motor abilities in the affected hand. Case presentation: Multimodal investigations included detailed TMS based motor mapping, motor evoked potentials (MEP), and Cortical Silent period (CSP) as well as functional magnetic resonance imaging (fMRI) of motor activity, MRI based lesion analysis and Diffusion Tensor Imaging (DTI) Tractography of corticospinal tract (CST). Anatomical analysis revealed a left hemisphere subinsular lesion interrupting the descending left CST at the level of the internal capsule. The absence of MEPs after intense TMS pulses to the ipsilesional M1, and the reversible suppression of ongoing electromyographic (EMG) activity (indexed by CSP) demonstrate a weak modulation of subcortical systems by the ipsilesional left frontal cortex, but an inability to induce efficient descending volleys from those cortical locations to right hand and forearm muscles. Functional MRI recordings under grasping and finger tapping patterns involving the affected hand showed slight signs of subcortical recruitment, as compared to the unaffected hand and hemisphere, as well as the expected cortical activations. Conclusions: The potential sources of motor voluntary activity for the affected hand in absence of MEPs are discussed. We conclude that multimodal analysis may contribute to a more accurate prognosis of stroke patients.

Computer-simulation study of magnetic relaxation in anisotropic magnetic systems

We present a computer-simulation study of the effect of the distribution of energy barriers in an anisotropic magnetic system on the relaxation behavior of the magnetization. While the relaxation law for the magnetization can be approximated in all cases by a time logarithmic decay, the law for the dependence of the magnetic viscosity with temperature is found to be quite sensitive to the shape of the distribution of barriers. The low-temperature region for the magnetic viscosity never extrapolates to a positive no-null value. Moreover our computer simulation results agree reasonably well with some recent relaxation experiments on highly anisotropic single-domain particles.

Memòria justificativa de recerca de la convocatòria MQD: PRESENT@: sala de graus virtual multidisciplinar

Un treball final de carrera (TFC) és un dels últims passos de molts estudis, com per exemple els graus d'enginyeria. Els estudiants solen presentar els resultats del seu projecte final en una presentació pública, on un comitè avalua el seu treball. Els estudiants, en aquesta activitat, s'ocupen de competències com ara: fer presentacions orals efectives en entorns públics, en una situació estressant. Però, es pot assolir aquesta competència en un entorn virtual?A la Universitat Oberta de Catalunya (UOC), una universitat 100% virtual, es proposa una solució basada en les presentacions en vídeo que es pugen en una eina, Present@, que els permet compartir les presentacions i permet fer preguntes i escriure les respostes en un entorn obert.Present@ ofereix una eina millorada per pujar vídeos, que simplifica el procés i fa que sigui apropiada per als estudiants de qualsevol àrea de coneixement. Però treballar amb vídeos va un pas més enllà i requereix també la tecnologia adequada per donar suport a aquest tipus d'arxius. Així, s'ha afegit al Present@ un servei d'"streaming", Kaltura. Amb aquest servei els estudiants poden pujar fàcilment gairebé qualsevol format de vídeo i és possible fer comentaris en vídeo.131 estudiants han estat usant el Present@ durant 4 semestres. Per avaluar l'eina, els estudiants han contestat un qüestionari i de les respostes rebudes es conclou que aquest enfocament permet als estudiants virtuals adquirir la major part de les competències relacionades amb el TFC i, en concret, amb la dissertació virtual en entorns virtuals. Potser l'única característica a què no s'enfronten és la tensió de les preguntes.És important assenyalar que, gràcies a les millores introduïdes, el Present@ està present, actualment en més de 100 aules a UOC i s'utilitza no només per al TFC, sinó també per explicar assignatures per ajudar els estudiants

El Turisme, present i futur

L’aparició del turisme ha estat una de les claus per a entendre la transformació que ha patit la plana del Baix Ter, tant pel que fa al paisatge humà com al paisatge físic. Les raons de la massificació del turisme a la Costa Brava serien la bellesa de l’entorn, la bona climatologia i l’oferta de serveis a un preu assequible

The role of financial and accounting methods as estimators of intrinsic value: the Tubacex case

En aquest treball estudiem si el valor intrínsec de Tubacex entre 1994-2013 coincideix amb la seva tendència bursàtil a llarg termini, tenint en compte part de la teoria defensada per Shiller. També verifiquem la possible infravaloració de l’acció de Tubacex a 31/12/13. A la primera part expliquem els principals mètodes de valoració d’empreses y a la segona part fem una anàlisi del sector en el que opera Tubacex (acer inoxidable) i calculem el valor de l’acció de Tubacex per mitjà de tres mètodes de valoració (Free Cash Flow, Cash Flow i Valor en Llibres). Apliquem aquests tres mètodes de valoració per verificar si com a mínim algun d’ells coincideix amb la tendència bursàtil a llarg termini.

Usability of Virtual Museums and the Diffusion of Cultural Heritage

Les prioritats per als museus canvien. La missió de la nova museologia és convertir els museus en llocs per a gaudir i aprendre, cosa que fa que hagin de dur a terme una gestió financera molt semblant a la d'una empresa social que competeixi en el sector del lleure. Amb el pas del temps, els museus han d'establir i aplicar els criteris necessaris per a la supervivència, aplanant el terreny perquè altres institucions públiques siguin més obertes en els seus esforços per comunicar i difondre el seu patrimoni. Ja podem començar a parlar d'algunes conclusions comunament acceptades sobre el comportament dels visitants, que són necessàries per a planificar exposicions futures que vegin l'aprenentatge com un procés constructiu, les col·leccions com a objectes amb significat i les mateixes exposicions com a mitjans de comunicació que haurien de transformar la manera de pensar de l'espectador i que estan al servei del mateix missatge. Sembla que internet representa un mitjà efectiu per a assolir aquests objectius, ja que és capaç (a) d'adaptar-se als interessos i les característiques intel·lectuals d'un públic divers; (b) de redescobrir els significats dels objectes i adquirir un reconeixement sociocultural del seu valor per mitjà del seu potencial interactiu, i (c) de fer ús d'elements atractius i estimulants perquè tothom en gaudeixi. Per a aquest propòsit, és bàsic fer-nos les preguntes següents: quins criteris ha de seguir un museu virtual per a optimar la difusió del seu patrimoni?; quins elements estimulen els usuaris a quedar-se en una pàgina web i fer visites virtuals que els siguin satisfactòries?; quin paper té la usabilitat de l'aplicació en tot això?

Value added logistical support service. Part 1 : Trends and new concept model

The aim of `Valssi' study was to find out the service requirements in `business-to-business' (B2B) markets and to present a new logistics service concept, where the traditional logistics service is expanded with significant manufacturing and value addedfacilities. The traditional third-party logistics service providers are not necessarily able to offer services, which cover widely the needs of potential customers. The study has been outlined to spare part markets in metal industry. In the second phase of the Valssi-project the aim is to examine the economical conditions and potentiality of the new logistics business concept. This research report (Part 1) concentrates on examining current trends in global and domestic logistics markets. Based on detailed survey among the participating companies, the study presents basis for a new logistics business concept model. The developed concept consists of 12 different service modules, which are split into deeper details of processes. The integration of worldwide supplier and service provider network together with customer companies systems is a challenge. The report focuses on evaluating the requirements for the new business concept from the customer-companies point of view. The study paints an overall picture of distribution and service provider network including an abstract about the software and system integration possibilities. As a result of the survey, it can be concluded that thereis need for the new business concept among the participating companies, and a modular service concept meets the requirements of them, because the new sophisticated concept considers the specialities involved in spare part logistics in metal industry.

Value added logistical support service: logistics cost structure and performance in the new concept. Part 3

The aim of this study is to present an Activity-Based Costing spreadsheet tool for analyzing the logistics costs. The tool can be used both by customer-companies and logistics service providers. The study discusses the influence of different activity models on costs. Additionally this paper discusses about the logistical performance across the total supply chain This study is carried out using ananalytical research approach and literature material has been used for supplementing the concerned research approach. Cost structure analysis was based on the theory of activity-based management. This study was outlined to spare part logistics in machine-shop industry. The outlines of logistics services and logisticalperformance discussed in this report are based on the new logistics business concept (LMS-concept), which has been presented earlier in the Valssi-project. Oneof the aims of this study is to increase awareness of different activity modelson logistics costs. The report paints an overall picture about the business environment and requirements for the new logistics concept.

Value added logistics in supply and demand chain. Smile. Part 2. eBusiness in a service business. Case: A maintenance and operations network in forest industry

VVALOSADE is a research project of professor Anita Lukka's VALORE research team in the Lappeenranta University of Technology. The VALOSADE includes the ELO technology program of Tekes. SMILE is one of four subprojects of the VALOSADE. The SMILE study focuses on the case of the company network that is composed of small and micro-sized mechanical maintenance service providers and forest industry as large-scale customers. The basic principle of the SMILE study is the communication and ebusiness in supply and demand networks. The aim of the study is to develop ebusiness strategy, ebusiness model and e-processes among the SME local service providers, and onthe other hand, between the local service provider network and the forest industry customers in a maintenance and operations service business. A literature review, interviews and benchmarking are used as research methods in this qualitative case study. The first SMILE report, 'Ebusiness between Global Company and Its Local SME Supplier Network', concentrated on creating background for the SMILE study by studying general trends of ebusiness in supply chains and networks of different industries. This second phase of the study concentrates on case network background, such as business relationships, information systems and business objectives; core processes in maintenance and operations service network; development needs in communication among the network participants; and ICT solutions to respond needs in changing environment. In the theory part of the report, different ebusiness models and frameworks are introduced. Those models and frameworks are compared to empirical case data. From that analysis of the empirical data, therecommendations for the development of the network information system are derived. In process industry such as the forest industry, it is crucial to achieve a high level of operational efficiency and reliability, which sets up great requirements for maintenance and operations. Therefore, partnerships or strategic alliances are needed between the network participants. In partnerships and alliances, deep communication is important, and therefore the information systems in the network also are critical. Communication, coordination and collaboration will increase in the case network in the future, because network resources must be optimised to improve competitive capability of the forest industry customers and theefficiency of their service providers. At present, ebusiness systems are not usual in this maintenance network. A network information system among the forest industry customers and their local service providers actually is the only genuinenetwork information system in this total network. However, the utilisation of that system has been quite insignificant. The current system does not add value enough either to the customers or to the local service providers. At present, thenetwork information system is the infomediary that share static information forthe network partners. The network information system should be the transaction intermediary, which integrates internal processes of the network companies; the network information system, which provides common standardised processes for thelocal service providers; and the infomediary, which share static and dynamic information on right time, on right partner, on right costs, on right format and on right quality. This study provides recommendations how to develop this system in the future to add value to the network companies. Ebusiness scenarios, vision, objectives, strategies, application architecture, ebusiness model, core processes and development strategy must be considered when the network information system will be developed in the next development step. The core processes in the case network are demand/capacity management, customer/supplier relationship management, service delivery management, knowledge management and cash flow management. Most benefits from ebusiness solutions come from the electrifying of operational level processes, such as service delivery management and cash flow management.

Els diccionaris de pronúncia del català: passat, present i futur

La llengua catalana disposa d’informació fonètica detallada multidialectal d’ençà que el Diccionari català-valencià-balear d’Alcover & Moll (1926/1930-1962/1968) fou enllestit quatre dècades enrere. Més endavant aparegué el primer diccionari de pronunciació del català (Bruguera, 1990, 20042), restringit al català central i amb una sola pronúncia per entrada -per tant, sense variants i amb informació reduïda en relació amb noms propis, manlleus i neologismes. Més endavant es publicà un vocabulari d’unes 2.000 paraules (Paloma & Rico, 2000) en els dos estàndards orals de Catalunya: central i nord-occidental, de caràcter normatiu i en transcripció ampla, suficient per als parlants catalans. Poc després veié la llum un diccionari de pronúncia de la varietat valenciana (Lacreu, ed., 2001), que conté un nombre elevat d’entrades, però sense informació onomàstica, morfològica ni relativa a la variació de la pronúncia d’aquest parlar. Finalment, es presenta un diccionari en procés d’elaboració d’unes 70.000 entrades i de més de 200.000 pronúncies. El Diccionari de pronúncia catalana (DPC) ha estat concebut per Julià-Muné & Creus com un diccionari de pronúncia descriptiva, en principi de les varietats nord-ocidental i central de la llengua catalana, que ofereix a més la pronunciació estàndard recomanada.

Content value chains modelling using a copyright ontology

Existing digital rights management (DRM) systems, initiatives like Creative Commons or research works as some digital rights ontologies provide limited support for content value chains modelling and management. This is becoming a critical issue as content markets start to profit from the possibilities of digital networks and the World Wide Web. The objective is to support the whole copyrighted content value chain across enterprise or business niches boundaries. Our proposal provides a framework that accommodates copyright law and a rich creation model in order to cope with all the creation life cycle stages. The dynamic aspects of value chains are modelled using a hybrid approach that combines ontology-based and rule-based mechanisms. The ontology implementation is based on Web Ontology Language and Description Logic (OWL-DL) reasoners, are directly used for license checking. On the other hand, for more complex aspects of the dynamics of content value chains, rule languages are the choice.

Nitrogen replacement value of alfalfa to corn and wheat under irrigated Mediterranean conditions

In crop rotations that include alfalfa (Medicago sativa L.), agronomic and environmental concerns mean that it is important to determine the N fertilizer contribution of this legume for subsequent crops in order to help to increase the sustainability of cropping systems. To determine the N fertilizer replacement value (FRV) of a 2-yr alfalfa crop on subsequent crops of corn (Zea mays L.) followed by wheat (Triticum aestivum L.) under irrigated Mediterranean conditions, two 4-yr rotations (alfalfa-corn-wheat and corn-corn-corn-wheat) were conducted from 2001 to 2004 in a Typic Xerofluvent soil. Corn yields were compared after two years of alfalfa and a third year of corn under monoculture and wheat yields were also compared after both rotations. Corn production after alfalfa outyielded monoculture corn at all four rates of N fertilizer application analyzed (0, 100, 200 and 300 kg N/ha). The FRV of 2-yr alfalfa for corn was about 160 kg N/ha. Wheat grown after the alfalfa-corn rotation outyielded that grown after corn under monoculture at both the rates of N studied (0 and 100 kg N/ha). The FRV of alfalfa for wheat following alfalfa-corn was about 76 kg N/ha. Soil NO3 -N content after alfalfa was greater than with the corn monoculture at all rates of N fertilizer application and this higher value persisted during the second crop after alfalfa. This was probably one of the reasons for the better yields associated with the alfalfa rotation. These results make a valuable contribution to irrigated agriculture under mediterranean conditions, show reasons for interest in rotating alfalfa with corn, and explain how it is possible to make savings when applying N fertilizer.

Extreme-value distributions and renormalization group

In the classical theorems of extreme value theory the limits of suitably rescaled maxima of sequences of independent, identically distributed random variables are studied. The vast majority of the literature on the subject deals with affine normalization. We argue that more general normalizations are natural from a mathematical and physical point of view and work them out. The problem is approached using the language of renormalization-group transformations in the space of probability densities. The limit distributions are fixed points of the transformation and the study of its differential around them allows a local analysis of the domains of attraction and the computation of finite-size corrections.
