The effect of level of feed intake on metabolizable energy values measured with adult roosters.

Two experiments were made with S.C. W.L. roosters to test the hypothesis that the apparent M.E. value of a feedingstuff is affected by the level of intake. In the first experiment the birds were starved for 18 hr. and then fed varying amounts of whole wheat. Excreta voided during the 24 hr. experimental period was collected quantitatively and assayed for gross energy. Energy voided as excreta increased in a linear manner as the intake of wheat increased. The apparent M.E. value also varied with wheat consumption according to the equation M.E. (kcal./g.) = 3.17X - 8.5/X where: 3.17 kcal. /g. is the true M.E. value of the wheat; 8.5 kcal. represents the sum of the metabolic fecal and endogenous urinary energy losses; and X is the weight of wheat consumed (g). A supplementary observation was that the metabolic fecal and endogenous nitrogen excretion of the roosters was 144 mg. /kg. /24 hr. In the second experiment corn oil was placed in the crops of starved roosters and the energy voided as excreta in 24 hr. was measured. The true M.E. value of the corn oil was 9.40 kcal. /g. but the apparent value varied with intake. It is therefore concluded that the original hypothesis is correct. The findings of these experiments may explain some of the reported variations in M.E. data. A new approach to the assay for M.E. is proposed.
Paediatric lung imaging: the times they are a-changin'

Until recently, functional tests were the most important tools for the diagnosis and monitoring of lung diseases in the paediatric population. Chest imaging has gained considerable importance for paediatric pulmonology as a diagnostic and monitoring tool to evaluate lung structure over the past decade. Since January 2016, a large number of papers have been published on innovations in chest computed tomography (CT) and/or magnetic resonance imaging (MRI) technology, acquisition techniques, image analysis strategies and their application in different disease areas. Together, these papers underline the importance and potential of chest imaging and image analysis for today's paediatric pulmonology practice. The focus of this review is chest CT and MRI, as these are, and will be, the modalities that will be increasingly used by most practices. Special attention is given to standardisation of image acquisition, image analysis and novel applications in chest MRI. The publications discussed underline the need for the paediatric pulmonology community to implement and integrate state-of-the-art imaging and image analysis modalities into their structure–function laboratory for the benefit of their patients. CT and MRI are increasingly replacing lung function tests to diagnose and monitor lung diseases in young children http://ow.ly/6KSb30hRdEz
Energy Minimization in Multi-Task Software-Defined Sensor Networks

After a decade of extensive research on application-specific wireless sensor networks (WSNs), the recent development of information and communication technologies makes it practical to realize the software-defined sensor networks (SDSNs), which are able to adapt to various application requirements and to fully explore the resources of WSNs. A sensor node in SDSN is able to conduct multiple tasks with different sensing targets simultaneously. A given sensing task usually involves multiple sensors to achieve a certain quality-of-sensing, e.g., coverage ratio. It is significant to design an energy-efficient sensor scheduling and management strategy with guaranteed quality-of-sensing for all tasks. To this end, three issues are investigated in this paper: 1) the subset of sensor nodes that shall be activated, i.e., sensor activation, 2) the task that each sensor node shall be assigned, i.e., task mapping, and 3) the sampling rate on a sensor for a target, i.e., sensing scheduling. They are jointly considered and formulated as a mixed-integer with quadratic constraints programming (MIQP) problem, which is then reformulated into a mixed-integer linear programming (MILP) formulation with low computation complexity via linearization. To deal with dynamic events such as sensor node participation and departure, during SDSN operations, an efficient online algorithm using local optimization is developed. Simulation results show that our proposed online algorithm approaches the globally optimized network energy efficiency with much lower rescheduling time and control overhead.
Noisy Signals: Understanding the Impact of Auditory Distraction on Web Search Tasks

More than half of all searches are now submitted on mobile devices, which can (and often are) used in various potentially distracting situations, such as travelling on a noisy train or when walking down a busy street. Research suggests that walking has negative effects on search performance and behaviour and that auditory distractions can impact on user input and affect perception of task duration. In this work we conduct a user study (n=16) using a simulated distracting condition to investigate how auditory distractions change perceived and objective search performance and behaviour. Our results suggest that noisy environments induce stress on users, causing them to feel additional perceived time pressure, leading to a reduced ability to identify task-relevant documents and a compulsion to finish the search task quickly.
Système de traduction automatique statistique Anglais-Arabe

Machine translation (MT) is the process of translating text written in a source language into text in a target language. In this article, we present our English-Arabic statistical machine translation system. First, we present the general process for setting up a statistical machine translation system, then we describe the tools as well as the different corpora we used to build our MT system. Our system was evaluated in terms of the BLUE score (24.51%)
Apparent digestibility of protein and amino acids in broiler chickens fed a corn-soybean diet supplemented with microbial phytase.

The effect of microbial phytase supplementation on CP and amino acid (AA) digestibility was investigated in a 28-d trial using 360 sexed, day-old broiler chickens fed corn-soybean meal diets. The experimental design was a completely randomized one with a 3 x 2 factorial arrangement of treatments. The variables included P and Ca levels and phytase: P and Ca levels were: normal P-normal Ca [0.45% available P (Pa), 1.0% Ca], low P-normal Ca (0.35% Pa, 1.0% Ca), and low P-low Ca (0.35 Pa and 0.6% Ca); and phytase at 0 and 600 U/kg diet. Phytase supplementation increased body weight gain (P < 0.014) and feed intake (P < 0.004) at 19 d in male chickens; in females, phytase increased (P < 0.012) only body weight gain at 19 d. The low P-normal Ca diet reduced (P < 0.05) feed intake and body weight gain in both sexes at 7, 14, and 19 d, compared to the normal P-normal Ca diet; the reduction of Ca in the low P diet prevented the above depression, resulting in body weight gain and feed intake to a level comparable to that of the normal P-normal Ca diet. Microbial phytase supplementation had no effect (P < 0.065) on the apparent ileal digestibility (AID) of CP or any AA except Met and Phe in male broiler chickens. In females, adding phytase increased the AID of all AA except Lys, Met, Phe, and Pro. The low P-normal Ca diet reduced (P < 0.05) the AID of Phe, Asp, and Ser in male chickens and reduced the AID of all the AA except Met and Pro in females compared to the normal P-normal Ca diet. The reduction of Ca in the low P diet prevented the depression of the AID of the AA caused by the low P-normal Ca diet, resulting in AID of AA having a level comparable to that of the normal P-normal Ca diet in both sexes. Phytase supplementation did not have any effect (P > 0.05) on apparent "fecal" digestibility (AFD) of CP or any of the AA in male chickens; however, in female chickens it increased the AFD of Thr, Asp, Glu, and Ser. In summary, phytase supplementation increased growth performance in both sexes; increased AID and AFD of most of the AA, particularly in female chickens. The optimum growth performance and AA digestibilities were obtained with the lowest input of resources, in the low P-low Ca diet supplemented with microbial phytase.
An on-board pedestrian detection and warning system with features of side pedestrian

Automotive Active Safety(AAS) is the main branch of intelligence automobile study and pedestrian detection is the key problem of AAS, because it is related with the casualties of most vehicle accidents. For on-board pedestrian detection algorithms, the main problem is to balance efficiency and accuracy to make the on-board system available in real scenes, so an on-board pedestrian detection and warning system with the algorithm considered the features of side pedestrian is proposed. The system includes two modules, pedestrian detecting and warning module. Haar feature and a cascade of stage classifiers trained by Adaboost are first applied, and then HOG feature and SVM classifier are used to refine false positives. To make these time-consuming algorithms available in real-time use, a divide-window method together with operator context scanning(OCS) method are applied to increase efficiency. To merge the velocity information of the automotive, the distance of the detected pedestrian is also obtained, so the system could judge if there is a potential danger for the pedestrian in the front. With a new dataset captured in urban environment with side pedestrians on zebra, the embedded system and its algorithm perform an on-board available result on side pedestrian detection.
Selective Attention to Faces in a Rapid Visual Stream: Hemispheric Differences in Enhancement and Suppression of Category-selective Neural Activity

In daily life, efficient perceptual categorization of faces occurs in dynamic and highly complex visual environments. Yet the role of selective attention in guiding face categorization has predominantly been studied under sparse and static viewing conditions, with little focus on disentangling the impact of attentional enhancement and suppression. Here we show that attentional enhancement and suppression exert a differential impact on face categorization supported by the left and right hemispheres. We recorded 128-channel EEG while participants viewed a 6-Hz stream of object images (buildings, animals, objects, etc.) with a face image embedded as every fifth image (i.e., OOOOFOOOOFOOOOF…). We isolated face-selective activity by measuring the response at the face presentation frequency (i.e., 6 Hz/5 = 1.2 Hz) under three conditions: Attend Faces, in which participants monitored the sequence for instances of female faces; Attend Objects, in which they responded to instances of guitars; and Baseline, in which they performed an orthogonal task on the central fixation cross. During the orthogonal task, face-specific activity was predominantly centered over the right occipitotemporal region. Actively attending to faces enhanced face-selective activity much more evidently in the left hemisphere than in the right, whereas attending to objects suppressed the face-selective response in both hemispheres to a comparable extent. In addition, the time courses of attentional enhancement and suppression did not overlap. These results suggest the left and right hemispheres support face-selective processing in distinct ways—where the right hemisphere is mandatorily engaged by faces and the left hemisphere is more flexibly recruited to serve current tasks demands.
Mining Weighted Closed Sequential Patterns in Large Databases

Previous algorithms mine the complete set of sequential patterns in large database efficiently, but when mining long sequential patterns in dense databases or using low minimum supports, it may produce many redundant patterns and some uninterested patterns. In this paper, a novel weighted closed sequential pattern mining algorithm (WCSpan) is presented, which implements the closed sequential pattern mining with weight constraints, so the uninterested patterns could be pruned and the redundancy could be reduced. This algorithm can find fewer but interested weighted sequential patterns by weighted pruning method and hash structure. The experimental results show that WCSpan algorithm is more efficient than CloSpan and WSpan.
Macromolecular Crowding Regulates the Gene Expression Profile by Limiting Diffusion

We seek to elucidate the role of macromolecular crowding in transcription and translation. It is well known that stochasticity in gene expression can lead to differential gene expression and heterogeneity in a cell population. Recent experimental observations by Tan et al. have improved our understanding of the functional role of macromolecular crowding. It can be inferred from their observations that macromolecular crowding can lead to robustness in gene expression, resulting in a more homogeneous cell population. We introduce a spatial stochastic model to provide insight into this process. Our results show that macromolecular crowding reduces noise (as measured by the kurtosis of the mRNA distribution) in a cell population by limiting the diffusion of transcription factors (i.e. removing the unstable intermediate states), and that crowding by large molecules reduces noise more efficiently than crowding by small molecules. Finally, our simulation results provide evidence that the local variation in chromatin density as well as the total volume exclusion of the chromatin in the nucleus can induce a homogenous cell population.
LaVAN: Localized and Visible Adversarial Noise

Most works on adversarial examples for deep-learning based image classifiers use noise that, while small, covers the entire image. We explore the case where the noise is allowed to be visible but confined to a small, localized patch of the image, without covering any of the main object(s) in the image. We show that it is possible to generate localized adversarial noises that cover only 2% of the pixels in the image, none of them over the main object, and that are transferable across images and locations, and successfully fool a state-of-the-art Inception v3 model with very high success rates.
Memory CD4 T cell subsets are kinetically heterogeneous and replenished from naive T cells at high levels

Characterising the longevity of immunological memory requires establishing the rules underlying the renewal and death of peripheral T cells. However, we lack knowledge of the population structure and how self-renewal and de novo influx contribute to the maintenance of memory compartments. Here, we characterise the kinetics and structure of murine CD4 T cell memory subsets by measuring the rates of influx of new cells and using detailed timecourses of DNA labelling that also distinguish the behaviour of recently divided and quiescent cells. We find that both effector and central memory CD4 T cells comprise subpopulations with highly divergent rates of turnover, and show that inflows of new cells sourced from the naive pool strongly impact estimates of memory cell lifetimes and division rates. We also demonstrate that the maintenance of CD4 T cell memory subsets in healthy mice is unexpectedly and strikingly reliant on this replenishment. DOI: http://dx.doi. org/10.7554/eLife.23013. 001
Review of LiFi visible light communications : research and use cases

LiFi is a networked wireless communication technology transforming solid-state indoor lighting into a backbone for information. The technology has reached maturity, with the first LiFi LED luminaire commercialized in 2016. Real life deployments with a variety of use cases, as well as staggering bandwidth improvements in the lab superior to 10 Gbps, hint to a luminous future for LiFi as a powerful complement or alternative to WiFi and 4G/5G.
A pilot test of a self-guided, home-based intervention to improve condom-related sexual experiences, attitudes, and behaviors among young women

ABSTRACT Objective: To conduct a pilot test of a brief, self-guided, home-based program designed to improve male condom use attitudes and behaviors among young women. Participants: Women aged 18–24 years from a large Midwestern University reporting having had penile–vaginal sex with two or more partners in the past 3 months. Sixty-seven enrolled; 91.0% completed the study. Methods: A repeated measures design was used, with assessments occurring at baseline, immediately post intervention (T2), and 30 days subsequent (T3). Results: Condom use errors and problems decreased, condom-related attitudes and self-efficacy improved, and experiences of condom-protected sex were rated more positively when comparing baseline with T2 and T3 scores. Further, the proportion of condom-protected episodes more than doubled between T1 and T3 for those in the lowest quartile for condom use at baseline. Conclusion: This low-resource, home-based program improved condom-related attitudes and promoted the correct and consistent use of condoms.
Effects of soft tissue augmentation procedures on peri‐implant health or disease: A systematic review and meta‐analysis

OBJECTIVE To review the dental literature in terms of soft tissue augmentation procedures and their influence on peri-implant health or disease in partially and fully edentulous patients. METHODS A MEDLINE search from 1966 to 2016 was performed to identify controlled clinical studies comparing soft tissue grafting versus no soft tissue grafting (maintenance) or two types of soft tissue grafting procedures at implant sites. The soft tissue grafting procedures included either an increase of keratinized tissue or an increase of the thickness of the peri-implant mucosa. Studies reporting on the peri-implant tissue health, as assessed by bleeding or gingival indices, were included in the review. The search was complemented by an additional hand search of all selected full-text articles and reviews published between 2011 and 2016. The initial search yielded a total number of 2,823 studies. Eligible studies were selected based on the inclusion criteria (finally included: four studies on gain of keratinized tissue; six studies on gain of mucosal thickness) and quality assessments conducted. Meta-analyses were applied whenever possible. RESULTS Soft tissue grafting procedures for gain of keratinized tissue resulted in a significantly greater improvement of gingival index values compared to maintenance groups (with or without keratinized tissue) [n = 2; WMD = 0.863; 95% CI (0.658; 1.067); p < . 001]. For final marginal bone levels, statistically significant differences were calculated in favor of an apically positioned flap (APF) plus autogenous grafts versus all control treatments (APF alone; APF plus a collagen matrix; maintenance without intervention [with or without residual keratinized tissue]) [n = 4; WMD = -0.175 mm; 95% CI: (-0.313; -0.037); p = . 013]. Soft tissue grafting procedures for gain of mucosal thickness did not result in significant improvements in bleeding indices over time, but in significantly less marginal bone loss over time [WMD = 0.110; 95% CI: 0.067; 0.154; p < . 001] and a borderline significance for marginal bone levels at the study endpoints compared to sites without grafting. CONCLUSIONS Within the limitations of this review, it was concluded that soft tissue grafting procedures result in more favorable peri-implant health: (i) for gain of keratinized mucosa using autogenous grafts with a greater improvement of bleeding indices and higher marginal bone levels; (ii) for gain of mucosal thickness using autogenous grafts with significantly less marginal bone loss.
Compromised antioxidant status associated with ascites in broilers.

Tissue infiltration by white blood cells in poultry with ascites has been reported, which could alter endogenous antioxidant status from oxidant stress. Therefore, the objective of this study was to determine the effect of ascites on ascorbic acid, tocopherol, and glutathione (GSH), which are major intracellular antioxidants. Broiler chicks (1 day) were placed in environmental chambers maintained with normal ventilation (Control) or under low ventilation, which produced a cumulative mortality of 31.3% due to ascites. At 3, 5, and 7 wk, lung and liver tissues were obtained from control birds (n = 5) and from birds in the low ventilation chamber with (ASC, n = 5) or without (NASC, n = 5) overt symptoms of ascites. There were no differences in tissue ascorbate, tocopherol, and GSH between the control and NASC groups with the exception of hepatic tocopherol at 7 wk, which was higher (P < .05) in NASC birds than in ASC and control birds. In general, lung and liver concentrations of all three antioxidants were lower (P < .05) in ASC birds than in NASC and control groups. Uric acid, a product of purine metabolism, was lower (P < .05) in liver and lung in ASC birds at 3 wk compared with control birds. However, uric acid concentrations in ASC birds were higher (P < .05) in the lung and serum at 5 wk, and in the liver at 7 wk compared with NASC and control birds. (ABSTRACT TRUNCATED AT 250 WORDS)
Phytochemical Investigation and Anti-Diarrheal Activity of Hydroalcoholic Extract of Fruits of Citrullus colocynthis (L.) Schrad. (Cucurbitaceae)

Background: Cucurbitaceae family is one of the best genetically assorted accumulations of restorative plants in the plant kingdom. Previous studies have suggested that Citrullus colocynthis (L.) Schrad. plant parts (root, stem, leaf, fruits, and seeds) have been utilized in the traditional system of medicine. Pharmacological activities reported for this plant include antioxidant activity, antimicrobial activity, anti-diabetic activity, anti-hyperlipidemic activity. The antidiarrheal activity of hydroalcoholic extract of fruits of this plant is reported for the first time in the present study.Objective: To evaluate the anti-diarrheal activity of Citrullus colocynthis (L.) Schrad. (Cucurbitaceae) in experimentally induced diarrhea in Wistar rats.Materials and methods: Hydroalcoholic extract of fruits of Citrullus colocynthis was examined for its acute toxicity on rats, in order to establish the safe doses. Castor oil induced diarrhea model and gastrointestinal motility test using barium sulfate milk were done to assess the antidiarrheal activity of plant extracts. Extract of Citrullus colocynthisat the dose of 50 mg/kg, 100 mg/kg and per se group (100 mg/kg) were used in Wistar rats of either sex. Loperamide (2 mg/kg) was taken as a standard drug in both the models.Results: Phytochemical analysis showed the presence of phenols, alkaloids, terpenoids, flavonoids, saponins, cardiac glycosides, steroids, tannins, and carbohydrates. The acute toxicity studies revealed that extract is relatively safe when given orally; no death was recorded at a dose of 2000 mg/kg. The dose of 100 mg/kg (P<0.001) and 50 mg/kg (P<0.01) of plant fruit extract significantly reduced defecation frequency in 6 h and also increased the latency time which showed similar effects as produced in loperamide treated group. Both doses of fruit extract and loperamide reduced the gastrointestinal motility in Wistar rats significantly (P<0.001). Conclusion: The hydroalcoholic extract of fruits of Citrullus colocynthis showed significant antidiarrheal activity and supports its use as a complementary and alternative medicine for treatment of diarrhea.
