EFFECT OF SPLIT FEEDING SYSTEM ON EGG PRODUCTION AND EGG QUALITY OF DANDARAWI LAYERS

This study was conducted to study the effect of split feeding system on egg production and egg quality of Dandarawi layers during their late phase of egg production cycle. A total of 100 Dandarawi Layers (12 months old) were divided into two groups. Each group was divided into 5 replicates (10 hens each). The first group was kept as control and fed one diet throughout the day (regular diet with optimum level of energy, protein and calcium). Whereas, the second group was fed according to split feeding system by having access to two diets throughout the day. The first diet (high energy, high protein and low calcium) offered from 6 am to 6 pm, and the second diet (low energy, low protein and high calcium) offered from 6 pm to 6 am. The diet offered throughout the daily hours was higher by 10% energy, 23% protein and lower by 50% calcium than the diet offered throughout the night hours. Body weight, feed intake, feed conversion ratio, egg production traits, egg quality were recorded, estimated or calculated. The results revealed that the split feeding system did not result in any significant (P>0.05) changes in body weight or body weight change during the experiment period from 12 to 16 months of age. Feed consumption was significantly decreased by 16.1 % and feed conversion ratio was significantly improved by 25 % by following split feeding system. There was a tendency to numerical increase in egg number by 9.47 %, egg laying rate % by 9.5%, and egg mass by 9 % for the split feeding system during the previous period. Split feeding system significantly increased egg length, egg width, albumen weight, albumin height and Haugh units compared with the control group. However, there was no significant influence of split feeding on egg weight, egg specific gravity, shape index, egg yolk quality, albumin%, and eggshell traits. It could be concluded that split feeding of Dandarawi layers at their late phase of egg laying cycle has led to decreasing feed consumption, improving feed conversion ratio, saving in feed cost and increasing egg number and egg mass.
Efficient and Robust RRAM-Based Convolutional Weight Mapping With Shifted and Duplicated Kernel

The conventional mapping method between RRAM array and convolutional weights faces two key challenges: 1) nonoptimal energy efficiency and 2) RRAM’s temporal variation. To address these challenges, we propose shift and duplicate kernel (SDK) convolutional weight mapping architecture. Each kernel is duplicated multiple times and rearranged on different bitlines in a shifted manner, enabling higher intralayer computational parallelism, and reducing the number of input data loading. Hence, this architecture reduces the computational latency and energy consumption in both forward and backward propagation phases. Furthermore, we have introduced a parallel-window size allocation algorithm and a kernel synchronization method. Our proposed parallel-window size allocation algorithm aims to balance the interlayer pipeline architecture, thus improving the overall energy efficiency and area efficiency. Our proposed kernel synchronization method uses an averaging method to suppress the effect of temporal variation during weight update, enhancing the system’s robustness for training. From our experiment results, our proposed architecture achieves $\sim 6.8\times $ area efficiency and $\sim 2.1\times $ energy efficiency over the conventional interlayer pipeline architecture. Significant improvement in classification accuracy by 21.7% under a temporal variation of 1%–5% is achieved during on-chip training task on the Cifar-10 dataset.
Drought frequency predicts life history strategies in Heliophila

Explaining variation in life history strategies is a long-standing goal of evolutionary biology. For plants, annual and perennial life histories are thought to reflect adaptation to environments that differ in the frequency of stress events such as drought. Here we test this hypothesis in Heliophila (Brassicaceae), a diverse genus of flowering plants native to Africa, by integrating 34 years of satellite-based drought measurements with 2192 herbaria occurrence records. Consistent with predictions from classic life history theory, we find that perennial Heliophila species occur in environments where droughts are significantly less frequent compared to annuals. These associations are predictive while controlling for phylogeny, lending support to the hypothesis that drought related natural selection has influenced the distributions of these strategies. Additionally, the collection dates of annual and perennial species indicate that annuals escape drought prone seasons during the seed phase of their life cycle. Together, these findings provide empirical support for classic hypotheses about the drivers of life history strategy in plants - that perennials out compete annuals in environments with less frequent drought and that annuals are adapted to environments with more frequent drought by escaping drought prone seasons as seeds.
Characterization of a 3.3-kV Si-SiC Hybrid Power Module in Half-Bridge Topology for Traction Inverter Application

A state-of-the-art 3.3-kV/450-A hybrid power module for the next generation traction inverter of rolling stock is reported in this paper, combining the silicon (Si) insulated-gate bipolar transistor (IGBT) and silicon carbide Schottky barrier diodes (SBDs) chips. Compared with the existing hybrid technology at the same voltage level, this module is characterized by a half-bridge topology, in which 6 IGBT and 12 SBD chips are integrated in each switch. The outnumbering of the diodes represents a promising mitigation to the low availability of SBDs at this voltage level. Both static and dynamic test of this module and an equivalent Si-based module are carried out comparatively. Apart from describing the features of compactness, low-inductance, and good current distribution among chips, this module is characterized by low turn-on current overshooting and turn-on loss of IGBTs, negligible diode reverse recovery time and loss, as well as flexible allowance of IGBT turn-on current rising rate $\boldsymbol{dI}/\boldsymbol{dt}$. A parameterized study is carried out to benchmark the advantage of this new topology. Based on the experimental results, the performance of the hybrid module in a three-phase traction inverter circuit is also evaluated by means of electro-thermal simulation. The hybrid module distinguishes itself by describing much lower power loss and junction temperature than its Si-based counterpart.
Data Analysis of MYO Signals during Upper Limb Movements of Enhanced Exoskeleton

Equipped with enhanced exoskeleton in the individual combat system can effectively enhance the soldiers’long-term load-bearing capacity and enhance the combat effectiveness of the army. In the exoskeleton control system, accurate recognition of human movement intentions plays an important role as upper-level control. This paper uses MYO armband as a sEMG sensor to collect 8 channels sEMG signals. Neural network method is applied to estimate the joint angles during arm movement. Motion capture system is used to verify the estimation accuracy. PCA (Principle Component Analysis) method is performed on the 8 channels data collected by MYO and processed dimensions were selected by experiments to make the estimation accuracy the highest. The results show that when the principal component dimension is selected as 8, which makes the estimation accuracy of the joint angles the highest.
Similar Conceptual Mapping of Novel Objects in Mixed‐ and Single‐Language Contexts in Fluent Basque‐Spanish Bilinguals

Participants learned the meaning of novel objects by listening to two complementary definitions while watching videos of the new object, in a single-language context (all in Spanish) or a mixed-language context (one definition in Basque, one in Spanish). Then, participants were asked to assess the degree of functional relatedness between novel and familiar objects in two conditions: Identical (both definitions overlap) or related (single definition overlap). Relatedness ratings differed significantly between conditions, but they were highly similar across language contexts. Furthermore, items in the identical condition elicited a P300-like event-related potential component, while related items elicited a wave of lesser amplitude. Critically, the amplitude differences between conditions did not differ between language contexts. No interaction was found with proficiency level across participants. In line with previous findings, we show no measurable impact of mixing languages during the establishment of a link between novel objects and existing conceptual representations in bilinguals.

Evidenz der Gruppenpsychotherapie – aktuelle Ergebnisse

In den letzten Jahren wurde die gesundheitspolitische Zielsetzung, ambulante Gruppenpsychotherapie zu fördern 1, mit einer Reihe von Maßnahmen unterstützt: bessere Vergütung, Kombination von Einzel- und Gruppenpsychotherapie 2, Reduktion der Gruppengröße und jüngst der angekündigte Wegfall der Gutachterpflicht. Dies stellt naturgemäß auch die Frage nach der Evidenzbasierung von Gruppenpsychotherapie, nicht zuletzt im Kontrast zur Einzeltherapie, die subjektiv nach wie vor von PatientInnen bevorzugt und auch für effektiver erachtet wird.
Design of A Novel Soft-switching Buck Converter with Passive Snubber for DC Charging Applications

This paper presents the analytical and design method of a passive Minimum Voltage Stress (MVS) soft-sowitching Buck converter with coupled inductors for DC charging applications. Zero Voltage Switching (ZVS) and Zero Current Switching (ZCS) can be realized to ahcieve 97.2% efficiency for a 18kW prototype. The proposed passive soft-switching Buck converter targets at minimized participation of auxiliary components during the power delivery phase, reducing the current magnitude through auxiliary diodes and inductor. Apart from soft-switching charateristics, adoption of interleaving operation and coupled magnetics result in fast load response and low ripple current, along with weight and volume reduction of the entire rectifier system as a whole. Operation principle, design method for passive snubber network and coupled inductor design has been analyzed. Simulaion and experimental results validate the effectiveness of the theoretical analysis.
A performance characteristic models of properties of dissolved plastic bottle modified bitumen for hot mix asphalt production

This paper investigated the effect of recycling Polyethylene Terephthalate (PET) waste bottles in dissolved (liquid) miscible forms (1, 3, 5, 7, 9, 11, 13, 15 and 17% by the weight) on the properties of standard straight-run grade bitumen. Classification, strength & safety compliance properties were carried out, according to provisions of standard testing procedures, at different percentages of (0-17) dissolved PET. Quantitative explanation of models for the trend of the variation of these properties were developed for each property with respect to % PET. Models were later compared with the corresponding statistic. The developed models for ductility, penetration, softening point, viscosity, flash and fire points, and specific gravity of the modified bitumen were -2.185(%PET) + 79.399, 2.456(%PET) + 47.401, 3.149(%PET) + 92.909, 1.244(%PET) + 75.622, 2.6801(%PET) + 254.69, 2.2036(%PET) + 307.65 and 0.0042(%PET) + 0.9589 with R2 values of 0.976, 0.969, 0.992, 0.976, 0.9917, 0.9774 and 0.9881 respectively. Results revealed that addition of PET (0 – 17 %) increased the softening, viscosity, specific gravity, flash and fire points of bitumen but decreased the penetration and ductility. It is concluded that PET can be used to improve the classification properties only but less for the mechanical properties of asphalt binder. However, satisfactory values which are in conformity with Nigerian, American and British standard specifications can be met at % PET of ≥2.01, ≥3.52, 11.09 – 14.58, 4.92 – 9.20, ≥1.98, ≥5.60, and ≥9.79 for ductility, viscosity, softening point, penetration, flash point, fire point and specific gravity respectively.
Hot surface ignition temperatures of hydrocarbon fuel vapor--air mixtures. [Autoignition temperatures and wire ignition temperatures]

Abstract : Laminar hot air jets of 1/8- to 3/4-inch diameter were used to determine the hot gas ignition temperatures of various combustible vapor-air mixtures. The combustibles were n-hexane, n-octane, n-decane, a hydrocarbon jet fuel (JP-6), and an adipate ester aircraft engine oil (MIL-L-7808). Minimum ignition temperatures occurred at a fuel to air weight ratio of about 0.5 and were not greatly sensitive to variations of fuel concentration. Moderate variations of jet velocity also had little influence on these ignition temperatures. However, these temperatures decreased with increase in heat source dimensions (jet diameter). The hot gas ignition temperatures of the combustibles were not necessarily much greater than corresponding autoignition and wire ignition temperatures when the size of the heat source and the ignition criterion were the same.

Variation of a Theme of Landau--Shanks in Positive Characteristic

Let A := F q [ t ] be a polynomial ring over a ﬁnite ﬁeld F q of odd characteristic and let D ∈ A be a square-free polynomial. Denote by N D ( n, q ) the number of polynomials f in A of degree n which may be represented in the form u · f = A 2 − DB 2 for some A, B ∈ A and u ∈ F × q , and by B D ( n, q ) the number of polynomials in A of degree n which can be represented by a primitive quadratic form of a given discriminant D ∈ A , not necessary square-free. If the class number of the maximal order of F q ( t, √ D ) is one, then we give very precise asymptotic formulas for N D ( n, q ). Moreover, we also give very precise asymptotic formulas for B D ( n, q ).
Post-Stimulus Time-Dependent Event Descriptor

Event-based image processing is a relatively new domain in the field of computer vision. Much research has been carried out on adapting event-based data to comply with established techniques from frame-based computer vision. On the contrary, this paper presents a descriptor which is designed specifically for direct use with event-based data and therefore can be considered to be a pure event-based vision descriptor as it only uses events emitted from event-based vision devices without transforming the data to accommodate frame-based vision techniques. This novel descriptor is known as the Post-stimulus Time-dependent Event Descriptor (P-TED). P-TED is comprised of two features extracted from event data which describe motion and the underlying pattern of transmission respectively. Furthermore a framework is presented which leverages the P-TED descriptor to classify motions within event data. This framework is compared against another state-of-the-art event-based vision descriptor as well as an established frame-based approach.

Beampattern Shaping for Coexistence of Cognitive MIMO Radar and MIMO Communications

This paper focuses on designing a set of transmit sequences for coexisting cognitive Multiple-Input Multiple-Output (MIMO) radar and MIMO communications (MRMC) systems. The aim is to shape the transmit beampattern to minimize the spatial Integrated Side-lobe Level (ISL) while having a good response on a desired direction in cognitive paradigm. The resulting non-convex, multi-variable optimization problem for the sequence design is addressed using the proposed Coordinate Descent (CD) framework under constant modulus and discrete phase constraints. The CD method has the capability of directly designing M-ary Phase Shift Keying (MPSK), which is important in practical applications. Numerical results indicate the superior performance of the proposed method over solutions based on Semi-definite Relaxation (SDR).
Population Fluctuation of Some Piercing-Sucking Pests and Their Associated Predator on Broad Bean Plants in Ismailia Governorate and Yield Loss for Aphid infestation

Faba bean is an important position between leguminous food crops in Egypt. A piercing-sucking pest associated with broad bean plants causes serious damage, directly by sucking plant juices or indirectly as the aphid insects are vectors to plant diseases. A field experiment was conducted at Wadi Elmalak, Ismailia Governorate, Egypt in winter growing seasons 2018/2019 and 2019/2020. To evaluate the population fluctuation of some piercing-sucking pests and the common natural enemies and relation to weather factors on broad bean plants. Results indicated that the important piercing-sucking pests, pea aphid, Acyrthosiphon pisum (Harris) were the most dominant, followed by Aphis craccivora Koch, while green peach aphid, Myzus persicae (Sulzer), Thrips tabaci Lind. and Jassid, Empoasca discipiens Poali were found in low densities throughout the two seasons. The eleven spotted lady beetle, Coccinella undecimpunctata L. , green lacewing, Chrysoperla carnea (Stephens), and seven-spotted lady beetle, Coccinella septempunctata L. are the most important predators which associated with the sucking insect pests on faba bean. The population fluctuation of piercing-sucking pests and associated predators were higher in the first season than in the second season. The pea aphid, A. pisum started with attacks broad bean in the second week of November and reached it has two peaks early January and in mid-May in the two successive years. The relationship between both of the population of piercing-sucking pests and associated predators and weather factors were studied. The loss in seed yield in the two successive seasons was evaluated all together being (330.0 kg. /fed). The avoidable losses in seeds yield were (19.18% per fed.) during two seasons
Vertical sleeve gastrectomy confers metabolic improvements by reducing intestinal bile acids and lipid absorption in mice

Significance Vertical sleeve gastrectomy (VSG) is a highly effective bariatric surgery that sustainably treats obesity and type 2 diabetes (T2D). However, the underlying mechanisms governing its metabolic benefits remain unclear. In this study, we have used four different genetically modified mouse lines to understand the link between bile acid circulation and metabolic effects of VSG. Instead of directly activating the nuclear bile acid receptor farnesoid X receptor (Fxr) in the liver or intestine, VSG reduces intestinal levels of bile acids, thereby decreasing fat absorption in the intestine. Given the rising popularity of bariatric surgeries to treat obesity and associated T2D, the results described herein provide mechanistic insights that may lead to safer noninvasive approaches to mimic the metabolic effects of bariatric surgery. Vertical sleeve gastrectomy (VSG) is one of the most effective and durable therapies for morbid obesity and its related complications. Although bile acids (BAs) have been implicated as downstream mediators of VSG, the specific mechanisms through which BA changes contribute to the metabolic effects of VSG remain poorly understood. Here, we confirm that high fat diet-fed global farnesoid X receptor (Fxr) knockout mice are resistant to the beneficial metabolic effects of VSG. However, the beneficial effects of VSG were retained in high fat diet-fed intestine- or liver-specific Fxr knockouts, and VSG did not result in Fxr activation in the liver or intestine of control mice. Instead, VSG decreased expression of positive hepatic Fxr target genes, including the bile salt export pump (Bsep) that delivers BAs to the biliary pathway. This reduced small intestine BA levels in mice, leading to lower intestinal fat absorption. These findings were verified in sterol 27-hydroxylase (Cyp27a1) knockout mice, which exhibited low intestinal BAs and fat absorption and did not show metabolic improvements following VSG. In addition, restoring small intestinal BA levels by dietary supplementation with taurocholic acid (TCA) partially blocked the beneficial effects of VSG. Altogether, these findings suggest that reductions in intestinal BAs and lipid absorption contribute to the metabolic benefits of VSG.
