Application of the multiphase optimization strategy to a pilot study: an empirical example targeting obesity among children of low-income mothers Abstract Background: Emerging approaches to building more efficient and effective behavioral interventions are becoming more widely available. The current paper provides an empirical example of the use of the engineering-inspired multiphase optimization strategy (MOST) to build a remotely delivered responsive parenting intervention to prevent obesity among children of low-income mothers with and without depressive symptoms. Methods: Participants were 107 mothers with (n = 45) and without (n = 62) depressive symptoms who had a child aged 12 to 42 months participating in the Women, Infants and Children program. Participants were randomized to one of sixteen experimental conditions using a factorial design that included a combination of the following eight remotely delivered intervention components: responsive feeding curriculum (given to all participants), parenting curriculum, portion size guidance, obesogenic risk assessment, personalized feedback on mealtime routines, feeding curriculum counseling, goal setting, mobile messaging, and social support. This design enabled efficient identification of components with low feasibility and acceptability.
Class-AB rail-to-rail CMOS buffer with bulk-driven super source followers

This paper describes a rail-to-rail CMOS analog voltage buffer designed to have extremely low static current consumption as well as high current drive capability. The buffer employs a complementary pair of super source followers, but a bulk-driven input device with the replica-biased scheme is utilized to eliminate the DC level shift, quasi-floating gate transistors to achieve class-AB performance, and a current switch which shifts between the complementary pair to allow rail-to-rail operation. The proposed buffer has been designed for a 0. 35μm CMOS technology to operate at a 1.8V supply voltage. The simulated results are provided to demonstrate that the total harmonic distortion for a 1.6Vpp 100kHz sine wave with a 68pF load is as low as -46dB, whilst the static current consumption remains under 8μA.
Compactification and supersymmetry breaking in M theory

Keeping $N=1$ supersymmetry in 4 dimensions and in the leading order, we discuss the various orbifold compactifications of M theory suggested by Horava and Witten on ${T}^{6}{/Z}_{3},$ ${T}^{6}{/Z}_{6},$ ${T}^{6}{/Z}_{12},$ and the compactification by keeping singlets under $\mathrm{SU}(2)\ifmmode\times\else\texttimes\fi{}U(1)$ symmetry, then the compactification on ${S}^{1}{/Z}_{2}. $ We also discuss the next to leading order K\"ahler potential, superpotential, and gauge kinetic function in the ${Z}_{12}$ case. In addition, we calculate the SUSY breaking soft terms and find out that the universality of the scalar masses will be violated, but the violation might be very small.
ZEST: A Hybrid Model on Predicting Passenger Demand for Chauffeured Car Service

Chauffeured car service based on mobile applications like Uber or Didi suffers from supply-demand disequilibrium, which can be alleviated by proper prediction on the distribution of passenger demand. In this paper, we propose a Zero-Grid Ensemble Spatio Temporal model (ZEST) to predict passenger demand with four predictors: a temporal predictor and a spatial predictor to model the influences of local and spatial factors separately, an ensemble predictor to combine the results of former two predictors comprehensively and a Zero-Grid predictor to predict zero demand areas specifically since any cruising within these areas costs extra waste on energy and time of driver. We demonstrate the performance of ZEST on actual operational data from ride-hailing applications with more than 6 million order records and 500 million GPS points. Experimental results indicate our model outperforms 5 other baseline models by over 10% both in MAE and sMAPE on the three-month datasets.
Detection, Identification and Characterization of Staphylococci in Street Vend Foods—Characterization of Staphylococcus Isolates

In the present investigation the diversity of the Staphylococcus species in different street vend food samples was studied. A total of 35 staphylococcal food isolates comprising of various species from 14 different street vend food samples were identified and characterized phenotypically. Staphylococcus aureus was found to be the most prevalent species in these foods. A PCR-RFLP analysis based on 16S rRNA gene was used for identification of Staphylococcus species. Isolates showing distinct RFLP pattern for AluI restriction digestion were selected for nucleotide sequence analysis. Phylogenetic tree constructed using the multiple alignments of 16S rRNA gene sequences of isolates showed a hotspot region of 169 bp and the relationship among species was evaluated by bootstrap values generated in phylogenetic analysis. 16S rRNA gene sequences allowed bacterial identification that was reproducible and more accurate than that obtained by phenotypic testing. 16S rRNA gene sequence analysis would be helpful in timely and correct identification of pathogens.
Radio observational constraints on Galactic 3D-emission models

Context. Our position inside the Galaxy requires 3D-modelling to obtain the distribution of the Galactic magnetic field, cosmic- ray (CR) electrons and thermal electrons. Aims. Our intention is to find a Galactic 3D-model which agrees best with available radio observations. Methods. We constrain simulated all-sky maps in total intensity, lin ear polarization, and rotation measure (RM) by observations. For the simulated maps as a function of frequency we integrate in 15 ′ wide cones the emission along the line of sight calculated from Galactic 3D-models. We test a number of large-scale magnetic field configurations and take the properties of the warm inte rstellar medium into account. Results. From a comparison of simulated and observed maps we are able to constrain the regular large-scale Galactic magnetic field in the disk and the halo of the Galaxy. The local regular fi eld is 2� G and the average random field is about 3 � G. The known local excess of synchrotron emission originating either fr om enhanced CR electrons or random magnetic fields is able to e xplain the observed high-latitude synchrotron emission. The thermal electron model (NE2001) in conjunction with a proper fill ing factor accounts for the observed optically thin thermal emission and low frequency absorption by optically thick emission. A coupling factor between thermal electrons and the random magnetic field comp onent is proposed, which in addition to the small filling fact or of thermal electrons increases small-scale RM fluctuations an d thus accounts for the observed depolarization at 1.4 GHz. Conclusions. We conclude that an axisymmetric magnetic disk field configur ation with reversals inside the solar circle fits available observations best. Out of the plane a strong toroidal magnetic field with di fferent signs above and below the plane is needed to account for the observed high-latitude RMs. The large field strength is a consequence of the small thermal electron scale height of 1 kpc, which also limits the CR electron extent up to a height of 1 kpc not to contradict with the observed synchrotron emission out of the plane. Our preferred 3D-model fits the observed Galactic total intensi ty and polarized emission better than other models over a wide frequency range and also agrees with the observed RM from extragalactic sources.
Ten Years of Research on Fault Management in Grid Computing: A Systematic Mapping Study

BACKGROUND: There is a large body of literature on research about fault management in grid computing. Despite being a well-established research area, there are no systematic studies focusing on characterizing the sorts of research that have been conducted, identifying well-explored topics as well as opportunities for further research. OBJECTIVE: This study aims at surveying the existing research on fault management in grid computing in order to identify useful approaches and opportunities for future research. METHOD: We conducted a systematic mapping study to collect, classify and analyze the research literature on fault management in grid computing indexed by the main search engines in the field. RESULTS: Our study selected and classified 257 scientific papers and was able to answer five research questions regarding the distribution of the scientific production over the time and space. CONCLUSIONS: The majority of the selected studies focus on fault tolerance, with very few efforts towards fault prevention, prediction and removal.
JOB BUST, BABY BUST: THE SPANISH CASE

The unemployment rate in Spain has been exceptionally high for more than two decades by now. During the same period the fertility rate dropped dramatically r eaching the lowest level in the world. In this study we look for evidence of a link between the 'unemployment crisis' and the 'fertility crisis' in Spain. We examine the factors that affect individuals' ages at marriage and childbirth, focusing on the effects of male employment status. Our results suggest that spells of non-employment have a very strong negative effect on the probability of marriage and childbearing. Part-time or temporal employment also shows negative (but smaller) effects relative to full-time or permanent employment. These effects are strongest on the age at marriage and the age at first birth, while the effects on subsequent births are considerably reduced. Our results suggest that lack of stable jobs among young men is one important factor that has forced many young people to delay their marriage and childbearing, lowering the period fertility rate in Spain to the lowest level in the world.
Neuron navigator 3a regulates liver organogenesis during zebrafish embryogenesis

Endodermal organogenesis requires a precise orchestration of cell fate specification and cell movements, collectively coordinating organ size and shape. In Caenorhabditis elegans, uncoordinated-53 (unc-53) encodes a neural guidance molecule that directs axonal growth. One of the vertebrate homologs of unc-53 is neuron navigator 3 (Nav3). Here, we identified a novel vertebrate neuron navigator 3 isoform in zebrafish, nav3a, and we provide genetic evidence in loss- and gain-of-function experiments showing its functional role in endodermal organogenesis during zebrafish embryogenesis. In zebrafish embryos, nav3a expression was initiated at 22 hpf in the gut endoderm and at 40 hpf expanded to the newly formed liver bud. Endodermal nav3a expression was controlled by Wnt2bb signaling and was independent of FGF and BMP signaling. Morpholino-mediated knockdown of nav3a resulted in a significantly reduced liver size, and impaired development of pancreas and swim bladder. In vivo time-lapse imaging of liver development in nav3a morphants revealed a failure of hepatoblast movement out from the gut endoderm during the liver budding stage, with hepatoblasts being retained in the intestinal endoderm. In hepatocytes in vitro, nav3a acts as a positive modulator of actin assembly in lamellipodia and filipodia extensions, allowing cellular movement. Knockdown of nav3a in vitro impeded hepatocyte movement. Endodermal-specific overexpression of nav3a in vivo resulted in additional ectopic endodermal budding beyond the normal liver and pancreatic budding sites. We conclude that nav3a is required for directing endodermal organogenesis involving coordination of endodermal cell behavior.
Hypotensive Anesthesia in Orthognathic Surgery­a Review

​ Orthognathic surgeries are major surgical procedures carried out to treat dentofacial deformities involving the maxilla, the mandible or both in combination. Orthognathic surgeries are complex surgical procedures for which a considerable amount of blood loss is expected due to the high vascularity of the facial skeleton, resulting in the need for blood transfusion. Blood transfusions are generally considered to be safe. But they do carry some risk of complications such as fever, chills, urticaria, anaphylactic reactions and transmission of bacterial, viral or protozoal infections. Various methods have been employed in reducing perioperative blood loss and transfusion requirement. One of the methods is controlled hypotension during anesthesia or hypotensive anesthesia. The aim of this article is to provide an overview of hypotensive anesthesia in patient undergoing orthognathic surgery.
SPC03-3: A MIMO-MLSE Receiver for Electronic Dispersion Compensation of Multimode Optical Fibers

In this paper we propose a multiple-input, multiple-output (MIMO) maximum-likelihood sequence estimation (MLSE) receiver for electronic dispersion compensation (EDC) of multimode optical fibers at 10 Gb/s data rate. As the primary example of the effectiveness of the techniques introduced here we present a receiver for the emergent 10 GBASE-LRM standard for 10 Gb/s Ethernet over multimode optical fibers [1]. We show that an MLSE receiver provides an advantage of at least 2 dB over other receivers, such as the decision-feedback equalizer (DFE), on 99% of the local area network (LAN) multimode fiber population, as modeled by a database proposed by the IEEE 802.3aq Task Force [2]. The paper deals with both theoretical and practical aspects of the architecture. To enable the complete integration of this receiver as a single chip in current 90 nm CMOS technology, we propose the parallel-processing digital implementation of a feedforward equalizer (FFE) and a Viterbi decoder together with an interleaved front-end analog to digital converter (ADC). The MIMO structure jointly compensates for fundamental channel impairments such as multimode dispersion, and implementation-related effects such as the limitations of the analog front end (AFE), particularly the one known as fixed-pattern noise (FPN) [3]. As a result of the high speed operation, FPN has a major impact on performance. We show that, without compensation, FPN could result in a degradation of 7.86 dB. With the compensation proposed here, the latter is reduced to 0.23 dB.
System-level analysis and evaluation of SF-DC transmit mode in HSPA+ system

Cooperated multi-point technique in HSPA+ system has not been paid attention until the Single Frequency Dual Cell (SF-DC) mode, where one user equipment (UE) may be served by dual NodeBs simultaneously in the single carrier frequency network, is proposed recently. In the previous research, the system-level performance with SF-DC operation had not been studied comprehensively. The main contribution of this paper is to exploit SF-DC transmit mode in the perspective of the system level and evaluate the system-level performance of SF-DC in HSPA+ system with different simulation scenes. The impact of SF-DC on legacy UEs and the load balancing capability of SF-DC in asymmetric loading case are investigated properly in different channel conditions. System-level simulation results show that SF-DC transmit mode performs better compared with single point transmission and the influence of SF-DC mode on legacy UEs is negligible. It also reflects that SF-DC has the ability to balance load in asymmetric loading case.
Vulnerability and Social Exclusion: Risk in Adolescence and Old Age

Vulnerability can be defined as the quality or state of being exposed to the possibility of being attacked or harmed, either physically or emotionally. In this chapter, it is defined as a possible ability of an individual or a group to face, manage, and anticipate a possible problem. This concept of vulnerability is associated with that of risk factor for social isolation, and therefore to situations that can also lead to illness and lack of mental and physical health. It can have its roots in poverty, in social exclusion, in ethnicity, in disability or simply in disease or specific developmental phases in life. All these aspects reflect very important vulnerability factors among biological, psychological, social, and behavioral variables. To date, no one has highlighted together two critical moments in life in which this brain area undergoes important variations: adolescence, in which its development occurs, and old age, in which this area goes into cognitive decline with the relative loss of many higher cognitive functions. This knowledge can help to better understand the forms of exclusion due to vulnerability in order to develop new forms of social inclusion.
An overview of the PubChem BioAssay resource

The PubChem BioAssay database (http://pubchem.ncbi.nlm.nih.gov) is a public repository for biological activities of small molecules and small interfering RNAs (siRNAs) hosted by the US National Institutes of Health (NIH). It archives experimental descriptions of assays and biological test results and makes the information freely accessible to the public. A PubChem BioAssay data entry includes an assay description, a summary and detailed test results. Each assay record is linked to the molecular target, whenever possible, and is cross-referenced to other National Center for Biotechnology Information (NCBI) database records. ‘Related BioAssays’ are identified by examining the assay target relationship and activity profile of commonly tested compounds. A key goal of PubChem BioAssay is to make the biological activity information easily accessible through the NCBI information retrieval system-Entrez, and various web-based PubChem services. An integrated suite of data analysis tools are available to optimize the utility of the chemical structure and biological activity information within PubChem, enabling researchers to aggregate, compare and analyze biological test results contributed by multiple organizations. In this work, we describe the PubChem BioAssay database, including data model, bioassay deposition and utilities that PubChem provides for searching, downloading and analyzing the biological activity information contained therein.
Analyzing FOSS Collaboration and Social Dynamics with Temporal Social Networks

How can we understand FOSS collaboration better? Can social issues that emerge be identified and addressed before it is too late? Can the community heal itself, become more transparent and inclusive, and promote diversity? We propose a technique to address these issues by quantitative analysis of social dynamics in FOSS communities. We propose using social network analysis metrics to identify growth patterns and unhealthy dynamics; giving the community a heads-up when they can still take action to ensure the sustainability of the project.
Cheshire II at GeoCLEF: Fusion and Query Expansion for GIR

An exercise machine for simulating the stroke of a canoe paddle is disclosed. A tube is pivotably mounted on the longitudinal axis of a frame. A paddle-like shaft is pivotally connected to a frictional resistance element sidably mounted on the tube. The frictional resistance element provides greater resistance to movement in one directional sense than to movement in the other directional sense to that the stroke and return stroke of a canoe paddle can be simulated. The frictional resistance element is formed of an outer member having a conical inner surface and an inner member having a conical outer surface, the inner member being fabricated into two halves on either side of a longitudinal plane. The tube passes through a longitudinal bore of the inner member, the bore being lined with frictional material. Forces acting to move the frictional resistance element in a first direction cause the outer member to compress the halves of the inner member as a function of the cone angle. The compression of the halves of the inner member increases the frictional force between the tube and the inner member, thus resisting further movement. The compression is eliminated for movements in the opposite directional sense.
Mathematical modeling for the activation of t-lymphocytes: population balance modeling with non conventional growth law

This article focuses on the mathematical modeling techniques applied to the particulate processes in biological sciences particularly Immunology. T-cell activation is studied with respect to their surface protein (CD3) concentration that is described in-terms of two particulate processes, growth and birth processes. The production of new proteins and change in their concentrations (on cells) has created the idea of balance law in the form of hyperbolic problems. In order to add a new dimension to the problem, CPBM (Cell Population Balance Model) is used with respect to multi-proteins concentrations. A mathematical model is used to find analytical solution while Finite volume scheme is used to approximate numerically the solution of PBE (Population Balance Equation) in order to anticipate and analyze the density of activated T-cells according to the given initial protein concentration.
Serious Gaming as an Additional Learning Tool for Medical Education

Background Computer-based learning methodologies have become more prevalent in the last decade. Web based serious gaming and virtual patients are novel in medical education, which have the potential to become important tools to improve today's medical students' knowledge and performance.Methods A total of 81 medical students participated in our study. They were either assigned to an intervention group or a control group . The intervention group completed a serious game module designed for Basic Life Support education. The control group received a theoretical lecture on the same content. On the next day both groups received simulation-based hands-on training for BLS using the same criteria. All students were assessed with an Objective Structured Clinical Examination (OSCE) the following week. Results There was no difference between the intervention group that used a web based serious game module for BLS and the control group that received a standard theoretical lecture from the faculty. Discussion and Conclusion Computer based interactive serious games seem to present a favourable additional tool for medical education. OSCE results imply, that the use of serious games as a self-learning strategy can be as useful as theoretical lectures; which means that it is saving time of learners and educators

Selective dimensional admittance control for versatile manipulation

Catastrophic disasters such as radioactive contamination, demand that rescuers to face life-threatening risk. Thus, the need for the robot to replace the person in numerous instances has emerged. Recently the mission demands of the DARPA Robotics Challenge (DRC) competition showed that robots need many control methods to replace humans in disaster environments. Thus, in this paper, a versatile admittance control method for various missions such as opening doors, drilling, and removing obstacles is introduced. It acts as a virtual admittance in a properly selected dimension according to the given task in Cartesian space. The door opening task was performed to verify the effectiveness of the proposed algorithm, where the three-dimensional admittance control and a trajectory generation algorithm were applied. The result showed that the performance and adaptation were comparable to human motion.
