A Smartphone-Based Prototype System for Incident/Work Zone Management Driven by Crowd-Sourced Data, 2015

This project develops a smartphone-based prototype system that supplements the 511 system to improve its dynamic traffic routing service to state highway users under non-recurrent congestion. This system will save considerable time to provide crucial traffic information and en-route assistance to travelers for them to avoid being trapped in traffic congestion due to accidents, work zones, hazards, or special events. It also creates a feedback loop between travelers and responsible agencies that enable the state to effectively collect, fuse, and analyze crowd-sourced data for next-gen transportation planning and management. This project can result in substantial economic savings (e.g. less traffic congestion, reduced fuel wastage and emissions) and safety benefits for the freight industry and society due to better dissemination of real-time traffic information by highway users. Such benefits will increase significantly in future with the expected increase in freight traffic on the network. The proposed system also has the flexibility to be integrated with various transportation management modules to assist state agencies to improve transportation services and daily operations.

Early stage primary bone lymphoma : a retrospective, multicenter rare cancer network (RCN) study

IntroductionLe lymphome primaire de l'os (LPO) représente moins de 1% de tous les lymphomes malins. Dans cette étude, nous avons évalué le profil de la maladie, les résultats thérapeutiques, et les facteurs pronostiques d'une série consécutive de patients atteints de LPO de stade I et II. Matériel et méthodeDans treize institutions du Réseau des Cancers Rares (Rare Cancer Network), 116 patients ont été traités pour un LPO entre 1987 et 2008, et sont l'objet de cette étude rétrospective. Quatre-vingt-sept patients ont subi une chimioradiothérapie (CXRT) sans (78), ou avec (9) une chirurgie, 15 ont bénéficié de radiothérapie (RT) sans (13), ou avec (2) chirurgie, 14 d'une chimiothérapie (CXT) sans (9), ou avec (5) chirurgie. La dose médiane de RT était de 40 Gy (4-60). Le nombre médian de cycles de CXT était de 6 (2-8). Le suivi médian était de 41 mois (6-242). RésultatsLe taux de réponse global à la fin du traitement était de 91% (74% de réponses complètes et 17% de réponses partielles). Une récidive locale ou une progression ont été observées chez 12 (10%) patients et une récidive systémique chez 17 (15%) patients. La survie globale, la survie spécifique, et le contrôle local à 5 ans ont été de 76%, 78% et 92%, respectivement. En analyse univariée (log-rank test), les facteurs pronostiques favorables pour la survie globale et la survie spécifique étaient: un indice pronostique international (IPI) inférieur ou égale à 1 (P = 0.009), un grade histologique élevé (P = 0.04), une CXRT (P = 0.05), une CXT (P = 0.0004), une réponse complète (P <0.0001), et une dose de supérieure à 40 Gy (p = 0.005). Concernant le contrôle local, seules la rémission complète et stade I ont été des facteurs favorables. En analyse multivariée, le score IPI, la dose de RT, la rémission complète, et la CXT ont influencé le résultat de façon indépendante en ce qui concerne la survie globale et la survie spécifique. La rémission complète a été le seul facteur prédictif pour le contrôle local. ConclusionCette étude multicentrique rétrospective confirme le bon pronostic du LPO de stade précoce traité par une combinaison de chimio-radiothérapie. Une dose de suffisant de radiothérapie et un nombre adéquat de cycles de chimiothérapie ont été suivis des résultats les plus favorables.

Lane-Departure Safety Countermeasures: Strategic Action Plan for the Iowa Department of Transportation, 2011

Lane departure crashes are the single largest category of fatal and major injury crashes in Iowa. The Iowa Department of Transportation (DOT) estimates that 60 percent of roadway-related fatal crashes are lane departures and that 39 percent of Iowa’s fatal crashes are single-vehicle run-off-road (SVROR) crashes. Addressing roadway departure was identified as one of the top eight program strategies for the Iowa DOT in their Comprehensive Highway Safety Plan (CHSP). The goal is to reduce lane departure crashes and their consequences through lane departure-related design standards and policies including paved shoulders, centerline and shoulder rumble strips, pavement markings, signs, and median barriers. Lane-Departure Safety Countermeasures: Strategic Action Plan for the Iowa Department of Transportation outlines roadway countermeasures that can be used to address lane departure crashes. This guidance report was prepared by the Institute for Transportation (InTrans) at Iowa State University for the Iowa DOT. The content reflects input from and multiple reviews by both a technical advisory committee and other knowledgeable individuals with the Iowa DOT.

Development and evaluation of neural network models to estimate daily solar radiation at Córdoba, Argentina

The objective of this work was to develop neural network models of backpropagation type to estimate solar radiation based on extraterrestrial radiation data, daily temperature range, precipitation, cloudiness and relative sunshine duration. Data from Córdoba, Argentina, were used for development and validation. The behaviour and adjustment between values observed and estimates obtained by neural networks for different combinations of input were assessed. These estimations showed root mean square error between 3.15 and 3.88 MJ m-2 d-1 . The latter corresponds to the model that calculates radiation using only precipitation and daily temperature range. In all models, results show good adjustment to seasonal solar radiation. These results allow inferring the adequate performance and pertinence of this methodology to estimate complex phenomena, such as solar radiation.

Family history of cancer and the risk of cancer: a network of case-control studies.

BACKGROUND: The risk of many cancers is higher in subjects with a family history (FH) of cancer at a concordant site. However, few studies investigated FH of cancer at discordant sites. PATIENTS AND METHODS: This study is based on a network of Italian and Swiss case-control studies on 13 cancer sites conducted between 1991 and 2009, and including more than 12 000 cases and 11 000 controls. We collected information on history of any cancer in first degree relatives, and age at diagnosis. Odds ratios (ORs) for FH were calculated by multiple logistic regression models, adjusted for major confounding factors. RESULTS: All sites showed an excess risk in relation to FH of cancer at the same site. Increased risks were also found for oral and pharyngeal cancer and FH of laryngeal cancer (OR = 3.3), esophageal cancer and FH of oral and pharyngeal cancer (OR = 4.1), breast cancer and FH of colorectal cancer (OR = 1.5) and of hemolymphopoietic cancers (OR = 1.7), ovarian cancer and FH of breast cancer (OR = 2.3), and prostate cancer and FH of bladder cancer (OR = 3.4). For most cancer sites, the association with FH was stronger when the proband was affected at age <60 years. CONCLUSIONS: Our results point to several potential cancer syndromes that appear among close relatives and may indicate the presence of genetic factors influencing multiple cancer sites.

Differences of Functional Connectivity Brain Network in Emotional Judgment

Using combined emotional stimuli, combining photos of faces and recording of voices, we investigated the neural dynamics of emotional judgment using scalp EEG recordings. Stimuli could be either combioned in a congruent, or a non-congruent way.. As many evidences show the major role of alpha in emotional processing, the alpha band was subjected to be analyzed. Analysis was performed by computing the synchronization of the EEGs and the conditions congruent vs. non-congruent were compared using statistical tools. The obtained results demonstrate that scalp EEG ccould be used as a tool to investigate the neural dynamics of emotional valence and discriminate various emotions (angry, happy and neutral stimuli).

Report and Specification for Transportation Program Management System, HR-394, 1997

TPMS is proposed as a distributed, PC-based system for automating two processes required for road improvements in Iowa: a) the annual preparation, submission, and approval of road improvement programs. b) the ongoing process of developing plans and obtaining approval for projects to be let for bids.

Transportation Program Management System, HR-394, 2003

HR-394 was a software and database development project. Via funding provided by the Iowa Highway Research Board, the Iowa County Engineer's Association Service Bureau oversaw the planning and implementation of an Internet based application that supports two major local-government transportation project activities: Project programming and Development tracking. The goals were to reduce errors and inconsistencies, speed up the processes, link people to both project data and each other, and build a framework that could eventually support a 'paperless' work flow. The work started in 1999 and initial development was completed by the fall of 2002. Since going live, several 'piggy back' applications have been required to make the Programming side better fit actual work procedures. This part of the system has proven adequate but will be rewritten in 2004 to make it easier to use. The original development side module was rejected by the users and so had to be rewritten in 2003. The second version has proven much better, is heavily used, and is interconnected with Iowa DOT project data systems. Now that the system is in operation, it will be maintained and operated by the ICEA Service Bureau as an ongoing service function.
