Storm Water Management Model Sensitivity to Different Design Storm Types and Parameters: The Case of Tangier Experimental Basin, Morocco

Rainfall records with time steps less than 15 min, which are required for designing storm water sewerage in urban areas, are rarely available throughout the Moroccan territory. The study was conducted with the objective to tackle this problem through the use of design storm structures with time steps that vary from 5 to 15 min. For this purpose, we used two structural families of design storms: (i) design storms derived from Intensity-Duration-Frequency (IDF) curves of Chicago, Composite, Desbordes, Watt, Weibull, Uniform, and Triangular design storm types; (ii) design storms from the Soil Conservation Service (SCS) synthetic rainfall. The selected design storm structures are those adapted to the rainfall distribution of Tangiers experimental basin and their resulted peak flows are comparable to the flow generated using the synthetic rainfall events. We also did sensitivity analysis for the Storm Water Management Model (SWMM) to changes of different design storm structural parameters, which includes storm duration, time steps, and intensity peak position. We evaluated how changes on these parameters affect peak flows and runoff volumes. In addition, Principal Component Analysis (PCA) method was used to validate the sensitivity analysis by identifying key storm parameters that significantly affect peak flows and Runoff volumes. SWMM model calibration results showed that the Desbordres and Chicago structures best fitted observed flow. Moreover, comparison of different SCS synthetic rainfall forms to observed rainfall events retains that of type 1. Furthermore, the Weibull and watt storms have both a shape parameter that has been calibrated by using the observed events. Overall, simulation results confirmed that peak flow was greatly affected by design storm structures, but was not closely correlated with rainfall intensity.
Decline of genetic variability in a captive population of Pacific white shrimp Penaeus (Litopenaeus) vannamei using microsatellite and pedigree information

Background : The objective of this study was to estimate the decline of genetic variability and the changes in effective population size in three shrimp populations. One was a wild population collected at several points in the Mexican Pacific Ocean. The other two populations were different generations (7 and 9) from a captive population selected for growth and survival. Microsatellite markers and pedigree were both used to assess genetic variability and effective population size. Results : Using 26 loci, both captive populations showed a decline in the expected heterozygosity (20%) and allelic diversity indices (48 to 91%) compared to the wild population (P 0.05). Effective population size estimates based on microsatellites declined from 48.2 to 64.0% in cultured populations (P Conclusions : An important decline of genetic variability in the cultured selected population due to domestication, and evidence of a further smaller decline in effective population size across generations in the selected population were observed when analyzing pedigree (41%) and microsatellite data (37%). Pedigree keeping is required to prevent the decline of effective population size and maintain genetic variability in shrimp breeding programs, while microsatellites are useful to assess effective population size changes at the population level.
On the Abundance of Large Primes with Small B-smooth values for p-1: An Aspect of Integer Factorization

— The security of RSA public key cryptography and RSA digital signature relies on the assumption of the hardness of the factorization of integers. Since the inception of RSA, there have been a series of proposals for factorizing large integers. A handful of integer factorization methods rely on the fact that the prime factor (cid:1816) having smooth p -1 value. Pollard’s p -1 is a method heavily based on this fact. It takes sub-exponential time for certain integers though not suitable for all integers. This paper experiments on the abundance (or scarcity) of smooth p -1 for large primes by examining their availability and suitability.
Metabolic Syndrome in Young Urban Adults : Natural Evolution in One Year

Introduction: Metabolic syndrome (MS) is diagnosed in an individual if any three of the five risk factors for metabolic syndrome are present. These five risk factors are elevated waist circumference, blood pressure, fasting blood glucose, serum triglyceride and lowered high density lipoprotein. Although the long term natural evolution of MS has been reported yet there is insufficient research on the changes in risk factors of MS after one year of diagnosis. Objective: To evaluate changes in risk factors of metabolic syndrome after one year of its identification in young college going students of an urban Northern India population Material and method: Height, weight, body mass index and various risk factors for metabolic syndrome such as waist circumference, blood pressure, fasting blood sugar, triglycerides and High Density Lipoprotein were assessed at baseline and after one year. International Physical Activity Questionnaire was used to objectively assess physical activity levels of the participants. Results: Out of 88 participants, 16 participants were diagnosed with MS at baseline but after one year the number reduced to 8. Percentage decrease in triglyceride levels (13.5%) was maximum followed by decline in waist circumference (8.9%) fasting blood glucose showed an increase by 6.6%. However, HDL, blood pressure, weight and BMI showed no significant change after one year. 70.6% of participants showed reduction in WC followed by reduction in fasting blood glucose of and triglyceride levels of 66.7% participants. Elevation of HDL levels was observed in 38.5% of the participants. Thus there was least improvement in HDL in the study population after one year. The increase in IPAQ physical activity scores after one year as compared to baseline was not statistically significant but the total sitting and average sitting time showed a statistically significant decline after one year. Conclusion: The incidence of MS shows a 49.7% decline after one year even when no specific dietary or physical activity advise is given to the participants. Although mean values of triglycerides showed the largest decrease after one year yet decline in waist circumference was seen in maximum percentage of participants. There was least improvement in HDL in the study population after one year.

CSBN : A Hybrid Approach For Survival Time Prediction With Missing Data

Survival prediction models most commonly use Cox Proportional Hazards (CPH) models, and are frequently used in medical statistics and clinical practice. However, such models underperform when the predictor variables are missing. By building Bayesian networks we automatically construct a model with the most important risk factors and relationships between risk factors and Bayesian networks are able to infer the likely values of missing data. We therefore propose a hybrid solution, consisting of a CPH model and a BN, where the predictive variables in the CPH model are the child nodes of a BN, which we call CSBN. We learn the CPH and BN models separately, using standard techniques, with the only constraint being that the variables that are predictors in the CPH model are child nodes in the BN. This allows us to fuse the two models, using the predictors of the CPH models as the join points. We test our approach by examining the performance of the CPH model, against the hybrid CSBN model, using both complete data cases and in cases with missing data. We calculate the performance of the survival prediction for both CPH and CSBN using the C-index and a normalised error function as metrics. For the CPH model, predictive error was significantly larger for missing data (±3120.8 days) compared to complete data (±1171.5 days; p = 3.6e − 07). This was also true for the CSBN ±1387.3 days for missing data compared with ±1171.5 days with complete data (p = 0.01568). However, with missing data, the predictive error was significantly larger for the CPH model (±3120.8 days) than the CSBN (±1171.5 days; p = 0.03274). In conclusion the CSBN methodology provides a more effective method of predicting survival when using incomplete data.
Hand Hygiene Analyzed by Video Recording

Objective : The aim of this study is to evaluate the hand hygiene and isolation precaution adhesion of the healthcare workers in routine cares. Methods : In an infectious diseases care unit of a university hospital in Marseille, France, we designed an observational study at evaluating the hand hygiene and isolation precaution adhesion of the healthcare workers in routine cares by remote video recording. The care team including nurses, assistant nurses, housekeepers and physicians was monitored from November 30th (2012) to February 13th (2013). From a video camera was placed inside patient room, healthcare workers paths were recorded from entrance to exit of the patient’s room. Hand hygiene disinfection as well as gloves and mask wearing in isolation precautions were observed. A video camera was placed inside patient room. Healthcare workers paths were recorded from entrance to exit of the patient’s room. A nurse and a sociologist analyzed further videos. Hand hygiene disinfection as well as gloves and mask wearing in isolation precaution were observed. Results : A total of 756 videos were captures. 249 were rejected because they were not contributive and 507 videos (811 Healthcare workers paths) were analyzed. Healthcare workers had hand disinfection at least one time in the path in 28.2%. Hand disinfection at entrance and exit of the bedroom is respected in 6.2%. The meal tray delivery is associated with a lower hand hygiene practice. The glove wearing adhesion is 51.2% in Clostridium difficile contact precaution, and conformity to protocol is 17.5%. Wearing gloves impairs hand disinfection especially in situation where gloves are not part of the protocol (38.7%). Adhesion to mask wearing in airborne precaution is 90.7%.
Market conduct and performance of wild and semi-wild food plants traded in Bunyoro-Kitara Kingdom, Uganda

This study assessed the market conduct and performance of wild and semi-wild food plants (WSWFPs) traded in Bunyoro-Kitara Kingdom, Uganda. A rapid market survey (RMS) was conducted in 17 local markets in Kibanda County. Market prices and weekly volumes of traded WSWFPs were compared with some of the selected conventional food plants traded in the same locality. Weekly volumes of traded WSWFPs based on the usual units of the measurement (including bundles and heaps) within the markets were estimated per species sold. The profit margin was computed per traded species. Transport expenses were excluded in the cost computation because only 4% of the traders incurred transport expenses in form of hired bicycles. Out of 62 WSWFPs belonging to 31 botanical families documented as edible in the Bunyoro-Kitara Kingdom, about 47% belonging to 12 botanical families were traded in formal and informal markets. Market information system was largely rudimentary and undeveloped, and traders rely mainly on information from fellow traders as well as their customers to make market decisions. Traded products were primarily delivered to markets on foot and using bicycles. Currently, there are no definite or formal mechanisms of setting prices of traded WSWFPs; most traders relied on the daily market demand, time and risks involved in gathering process, information of the price of substitute food and prices from other areas, knowledge of the past seasons’ prices, and on the costs incurred from the suppliers. With exception of few species such as Physalis peruviana and Basella alba , weekly volumes of traded WSWFPs were low as compared to most conventional food crops. On the other hand, prices of most traded WSWFPs were generally similar to those of alternative conventional food plants marketed in the area. Some WSWFPs like Hibiscus acetosella , B. alba and Hyptis spicigera (seeds), had higher market prices per unit measurement as compared to the related conventional food plants. Average weekly profits yielded from the trade of various WSWFPs were moderate and ranged from UGX 764.5 to 6754.2 (USD 0.38 to 3.36). The highest return came from species such as H. spicigera, Hibiscus sabdariffa, Aframomum angustifolium, Borassus aethiopum, B. alba, Solanum nigrum, Aframomum alboviolaceum and Canarium schweinfurthii .

INFLUENCE OF HORMONAL TREATMENTS AND OF SUCROSE ON THEMICROTUBERIZATION OF THREE POTATO VARIETIES (Solanum tuberosum L.)ADAPTED TO AGROCLIMATIC CONDITIONS IN SENEGAL

In the situation of a research-development project on the in vitro production of potato seeds in Senegal, we attempted to improve the microtuberization of some varieties. The production of vitrotubers is one of the most efficient tools for the propagation of basic material, the transport of germplasm and the conservation of potato varieties cultivated after cleansing. It allows, at any period of the year, to obtain healthy seeds ready to be planted and which can be dispatched within long distances without any specific precaution. In this context, comparative studies have been achieved under darkness conditions and at 20°C, on two types of Murashige & Skoog (MS/2) media of tuberization, with, on the one hand, a sucrose concentration of 80 or 100 g L-1, without hormones and on the other with different hormonal combinations (Kinetin + BAP) or (Kinetin + Coumarin). Aida variety presents the best aptitude for the microtuberization with a rate of 91%. The sucrose concentration most favorable being 80 g L-1 for the Aida variety and 100 g L -1 for the Atlas and Odessa varieties. The Aida variety (88.5%) gave more microtubers when the hormonal combination Kinetin + BAP is added to the culture medium, compared to the Odessa (74.5%) and Atlas (66.5%) varieties. The replacement of the BAP by Coumarin in the hormonal combination was not beneficial. We noticed, indeed, a reduction of the microtuberization rate for all varieties whatever was the sucrose concentration added to the culture medium. The output in mass of the microtubers depends as well on the caliber and the number of microtubers.
Describing Packet Payload Structures using Lightweight Semantic Data Type Annotations ( Extended Abstract )

In the majority of wireless sensor networks, packet structures are statically defined at design time. At runtime, sensed data is then inserted into the payload fields prior to packet transmission. While this is efficient in terms of the required processing, the packet structure cannot be modified during runtime. However, in certain situations the need for adaptation of the packets to new requirements arises, e.g. when the energy source approaches depletion and energy-hungry sensors are deactivated to extend the node lifetime. The countermeasure of defining a multitude of packet structures to encounter any possible situation is infeasible both in terms of efforts and resource consumption. To address this limitation, we propose the annotation of data fields in outgoing packets by identifiers indicating the contained data types, so that any node can send payloads with dynamically defined contents. The size increase incurred by the use of annotations for each payload field can however become significant as the annotations must be sufficiently expressive to uniquely describe the payload field. To keep this size increment small, we present a supplementary approach that assigns binary aliases for the used data type annotations, thus increasing the payload space available for application data. This is especially useful as payload sizes in sensor networks are generally limited by the radio protocol, and fragmentation is expensive in terms of the according energy requirement.
1 Extinct Radionuclides and the Earliest Differentiation of the Earth and

The extinct 182Hf-182W and 146Sm-142Nd systems provide key chronological constraints on the major episodes of planetary differentiation. Both chronometers can be considered extinct after approximately 5–6 half-lives (i.e., after 50 Myr and 400 Myr respectively) and are therefore selectively sensitive to early events. Application of 182Hf-182W chronometry shows that segregation of the Earth’s core may have been complete no earlier than 30 Myr after formation of the solar system and probably involved at least partial re-equilibration of newly accreted metallic cores within the terrestrial magma ocean. The current best estimate for the termination of the major stage of Earth’s accretion and segregation of its core is provided by the age of the Moon, which formed as a result of a giant collision of a Marssized embryo with the proto-Earth. According to 182Hf-182W systematics this event occurred 50–150 Myr after CAI formation. As the Earth cooled down following the giant impact, crystallization of the magma ocean resulted in the formation of the earliest terrestrial crust. While virtually no remnant of this proto-crust survived in the present-day rock record, the isotopic fingerprint of this early event is recorded in the form of small 142Nd anomalies in early Archean rocks. These anomalies show that magma ocean solidification must have taken place 30–100 Myr after formation of the solar system. In contrast, 146Sm-142Nd systematics of lunar samples show that the lunar mantle may have remained partially molten until 300 Myr after CAI formation. Therefore, extinct chronometers indicate that accretion and differentiation of the Earth proceeded rapidly. The core, mantle and crust were completely differentiated less than 100 Myr after formation of the solar system.
Cuminum cyminum methanolic extract prevents oxidative modification of low density lipoproteins: Preliminary evidence on its anti-atherosclerotic potential

The significance of oxidative modification of LDL in the pathogenesis of atherosclerosis and the lack of efficient treatment intervention has led researchers to develop an effective therapy based on natural antioxidants. The present study provides preliminary evidence in support of the anti-atherosclerotic potential of methanolic extract of Cuminum cyminum L. (CC). We found that CC inhibited Cu2+ -mediated LDL oxidation as demonstrated by the ex vivo LDL oxidation kinetic study, the LDL oxidation products (malondialdehyde, lipid hydroperoxide and protein carbonyl), and ApoB fragmentation assay. It can be concluded that, CC efficiently alleviates experimentally induced oxidative changes and modifications of LDL. Since oxidative changes in LDL are prerequisite to onset of atherogenic changes, this study provides preliminary evidence on anti-atherosclerotic potential of CC
On the Raman O VI and related lines in classical novae

We critically examine the recent claimed detection of Raman scattered O VI at around 6830\AA\ in the iron curtain stage spectra of the classical CO nova V339 Del. The observed line variations are compatible in profile and timing of emission line strength with an excited state transition of neutral carbon. Line formation in classical nova ejecta is physically very different from that in symbiotic binaries, in which the O VI emission line is formed within the wind of the companion red giant at low differential velocity. The ejecta velocity and density structure prevent the scattering from producing analogous features. There might , however, be a broadband spectropolarimetric signature of the Raman process and also Rayleigh scattering at some stage in the expansion. We show that the neutral carbon spectrum, hitherto under-exploited for novae, is especially useful as a probe of the structure of the ejecta during the early, optically thick stages of the expansion
Improvement of Echo State Network Generalization by Selective Ensemble Learning Based on BPSO

The Echo State Network (ESN) is a novel and special type of recurrent neural network that has become increasingly popular in machine learning domains such as time series forecasting, data clustering, and nonlinear system identification. This network is characterized by large randomly constructed recurrent neural networks (RNN) called “reservoir”, in which the neurons are sparsely connected and the weights remain unchanged during training, leaving the simple training of the output layer. However, the reservoir is criticized for its randomness and instability because of the random initialization of the connectivity and weights. In this article, we introduced the selective ensemble learning based on BPSO to improve the generalization performance of ESN. Two widely studied tasks are used to prove the feasibility and priority of the selective ESN ensemble based on BPSO(SESNE-BPSO) model. And the results indicate that the SESNE-BPSO model performs better than the general ESN ensemble, the single standard ESN and several other improved ESN models.
Fisher Vector based on Full-covariance Gaussian Mixture Model

In image retrieval applications, the Fisher vector of the Gaussian mixture model (GMM) with a diagonalcovariance structure is known as a powerful tool to describe an image by aggregating local descriptors extracted from the image. In this paper, we propose the Fisher vector of the GMM with a full-covariance structure. The closed-form approximation of the GMM with a full-covariance structure is derived. Our observation is that the Fisher vector of a higher dimensional GMM yields higher image retrieval performance. The Fisher vector for the GMM with a blockdiagonal-covariance structure is also introduced to provide moderate dimensionality for the GMM. Experimental comparisons performed using two major datasets demonstrate that the proposed Fisher vector outperforms state-of-the-art algorithms.
EMU : A Transparent 3 D Robotic Manipulandum for Upper-Limb Rehabilitation

This paper introduces the EMU, a threedimensional robotic manipulandum for rehabilitation of the upper extremity for patients with neurological injury. The device has been designed to be highly transparent, have a large workspace, and allow the use of the hand for interaction with real-world objects to provide additional contextual cues during exercises. The transparency is achieved through the use of a capstan transmission for the drive joints; a hybrid serial parallel kinematics minimising moving inertia; and lightweight materials. An experimental protocol is reported here which demonstrates the transparency through a comparison to out-ofrobot movements, and with an existing rehabilitation robotic device. Additionally, an adjustable gravity compensation method is constructed, which minimises the torque required at the shoulder to carry the subject’s arm. These characteristics allow the EMU to serve as a multi-purpose platform for the further development of novel robot assisted rehabilitation strategies.
