description: Data loading can dominate deep neural network training time on large-scale systems. We present a comprehensive study on accelerating data loading performance in large-scale distributed training. We first identify performance and scalability issues in current data loading implementations. We then propose optimizations that utilize CPU resources to the data loader design. We use an analytical model to characterize the impact of data loading on the overall training time and establish the performance trend as we scale up distributed training. Our model suggests that I/O rate limits the scalability of distributed training, which inspires us to design a locality-aware data loading method. By utilizing software caches, our method can drastically reduce the data loading communication volume in comparison with the original data loading implementation. Finally, we evaluate the proposed optimizations with various experiments. We achieved more than 30x speedup in data loading using 256 nodes with 1,024 learners.

description: Here we report a new predictive model for autoignition temperature (AIT), an important physical parameter widely used to assess potential safety hazards of combustible materials. Available structure-AIT data extracted from different sources were critically analysed. Support vector regression (SVR) models on different data subsets were built in order to identify a reliable compound set on which a realistic model could be built. This led to a selection of the dataset containing 875 compounds annotated with AIT values. The thereupon-based SVR model performs reasonably well in cross-validation with the determination coefficient r2 = 0.77 and mean absolute error MAE = 37.8°C. External validation on 20 industrial compounds missing in the training set confirmed its good predictive power (MAE = 28.7°C).

description: Experimental observations of the ultrafast (less than 50 fs) demagnetization of Ni have so far defied theoretical explanations particularly since its spin-flipping time is much less than that resulting from spin-orbit and electron-lattice interactions. Through the application of an approach that benefits from spin-flip time-dependent density-functional theory and dynamical mean-field theory, we show that proper inclusion of electron correlations and memory (time-dependence of electron-electron interaction) effects leads to demagnetization at the femtosecond scale, in good agreement with experimental observations. Furthermore, our calculations reveal that this ultrafast demagnetization results mainly from spin-flip transitions from occupied to unoccupied orbitals implying a dynamical reduction of exchange splitting. These conclusions are found to be valid for a wide range of laser pulse amplitudes. They also pave the way for ab initio investigations of ultrafast charge and spin dynamics in a variety of quantum materials in which electron correlations may play a definitive role.

description: We analyze numerically the time-dependent linear operators that govern the dynamics of Eulerian correlation functions of a decaying passive scalar advected by a stationary, forced 2-dimensional Navier-Stokes turbulence. We show how to naturally discuss the dynamics in terms of effective compact operators that display Eulerian Statistically Preserved Structures which determine the anomalous scaling of the correlation functions. In passing we point out a bonus of the present approach, in providing analytic predictions for the time-dependent correlation functions in decaying turbulent transport.

description: We analyse the characteristics of interplanetary coronal mass ejections (ICMEs) during Solar Cycles 23 and 24. The present analysis is primarily based on the near-Earth ICME catalogue (Richardson and Cane, 2010). An important aspect of this study is to understand the near-Earth and geoeffective aspects of ICMEs in terms of their association (type II ICMEs) versus absence (non-type II ICMEs) of decameter-hectometer (DH) type II radio bursts, detected by Wind/WAVES and STEREOS/WAVES. Notably, DH type II radio bursts driven by a CME indicate powerful MHD shocks leaving the inner corona and entering the interplanetary medium. We find a drastic reduction in the occurrence of ICMEs by 56% in Solar Cycle 24 compared to the previous cycle (64 versus 147 events). Interestingly, despite a significant decrease in ICME/CME counts, both cycles contain almost the same fraction of type II ICMEs (~47%). Our analysis reveals that, even at a large distance of 1 AU, type II CMEs maintain significantly higher speeds compared to non-type II events (523 km/s versus 440 km/s). While there is an obvious trend of decrease in ICME transit times with increase in the CME initial speed, there also exists a noticeable wide range of transit times for a given CME speed. Contextually, Cycle 23 exhibits 10 events with shorter transit times ranging between 20-40 hours of predominantly type II categories while, interestingly, Cycle 24 almost completely lacks such "fast" events. We find a significant reduction in the parameter $V_{ICME} \times B_{z}$, the dawn to dusk electric field, by 39% during Solar Cycle 24 in comparison with the previous cycle. Further, $V_{ICME} \times B_{z}$ shows a strong correlation with Dst index, which even surpasses the consideration of $B_{z}$ and $V_{ICME}$ alone. The above results imply the crucial role of $V_{ICME} \times B_{z}$ toward effectively modulating the geoeffectiveness of ICMEs.

description: A new compact narrowband multiresonator microstrip filter design is presented in this paper as a candidate for use in modern wireless communication systems. The proposed filter structure is generated using Peano fractal curve geometry. The proposed filter structure is fractally generated using Peano fractal curve geometry. Two 2nd and 4th order Chebyshev bandpass filters have been designed based on the 2nd iteration Peano fractal curve at a design frequency of 2.45GHz using a substrate of a relative dielectric constant of 9.6 and thickness of 0.508 mm. Filter structures based on the second iteration Peano geometry leads to compact size single mode resonators with dimensions of about (0.075×0.086)λg. This article represents better miniaturization level compared with the other microstrip bandpass filters based on other space-filling geometries and designed at the same frequency using the same substrate material specifications. Simulation and theoretical performance of the resulting filter structures have been carried out using method of moments (MoM) based electromagnetic simulator IE3D, from Zeland Software Inc. The results also show that the proposed filter structures possess good return loss and transmission responses besides the size reduction gained, making them suitable for use in a wide variety of wireless communication applications.

description: Acetyl Coenzyme A Carboxylase (AccD6) is a homodimeric protein which is involved in the carboxylation of acetyl coenzyme A to produce malonyl coenzyme A, which plays an important role in the biosynthesis of fatty acid chain. However, studies suggest that AccD6 in combination with AccA3 produces malonyl co-A. Certain herbicides are known to inhibit plant ACC. Among these herbicides, haloxyfop was found to inhibit AccD6 at IC50 of 21.1 ± 1 µM. In this study, we have performed molecular docking of the Maybridge database consisting of ~55,000 compounds in the active site of the protein with haloxyfop as a reference molecule, followed by molecular dynamics study and biological activity determination of prioritized compounds. Out of the nine compounds selected for biological evaluation, three compounds – CD07230, HTS08529 and KM08871 – were found to exhibit anti-mycobacterial activity.

description: Group cohesiveness is a compelling and often studied composition in group dynamics and group performance. The enormous number of web images of groups of people can be used to develop an effective method to detect group cohesiveness. This paper introduces an automatic group cohesiveness prediction method for the 7th Emotion Recognition in the Wild (EmotiW 2019) Grand Challenge in the category of Group-based Cohesion Prediction. The task is to predict the cohesive level for a group of people in images. To tackle this problem, a hybrid network including regression models which are separately trained on face features, skeleton features, and scene features is proposed. Predicted regression values, corresponding to each feature, are fused for the final cohesive intensity. Experimental results demonstrate that the proposed hybrid network is effective and makes promising improvements. A mean squared error (MSE) of 0.444 is achieved on the testing sets which outperforms the baseline MSE of 0.5.

description: Abstract

Vitamin D has many essential roles for the proper functioning of the body, Argan oil (AO) is natural product recognized by its pharmacological properties in traditional medicine. Scientific evidence, which is scant, suggests a reduction in cardiovascular risk include several phenomena. This study aims to evaluate the effect of vitamin D and argan oil on phosphocalcic responses in obese and normal weight Moroccan population.  A randomized, double-blind, placebo-controlled study was conducted, the effects of daily supplementation of 600 IU of vitamin D3, for three months, in 48 people, 24 people of normal weight and average age of 42 years and 24 obese people with an average age of 42 years and having a normal vitamin D concentration or presenting an insufficiency defined by 25(OH)D levels less than 12 ng/ml. Vitamin D and argan oil supplementation increased significantly the vitamin D level in blood (p < 0.01; +67%) as compared with control group, For phosphorus, a significant decrease has shown after vitamin D supplementation in individuals with normal weight (P<0.05), but without effect in obese individuals (P> 0.05). In individuals with normal vitamin D status, a reduction in 25 (OH) D plasma concentration was recorded in control normal participants with normal during the experience (p<0.01). But an increase of vitamin D plasma concentration was detected in vitamin D supplement group. Vitamin D supplementation increases the 25-OH-D plasma concentrations in normal (p<0.05) and obese (p=0.05) participants. Combined supplementation in vitamin D and argan oil increases the level of vitamin D in individuals with deficiency in Vitamin D, and can be recommended for the population of Kenitra. Further studies seem be necessary to evaluate the clinical effects of such supplementation

description: Purpose: Double diffusion encoding (DDE) MRI enables the estimation of microscopic diffusion anisotropy, yielding valuable information on tissue microstructure. A recent study proposed that the acquisition of rotationally invariant DDE metrics, typically obtained using a spherical "5-design", could be greatly simplified by assuming Gaussian diffusion, facilitating reduced acquisition times that are more compatible with clinical settings. Here, we aim to validate the new minimal acquisition scheme against the standard DDE 5-design, and to quantify the proposed method's noise robustness to facilitate future clinical use. Methods: DDE MRI experiments were performed on both ex vivo and in vivo rat brains at 9.4 T using the 5-design and the proposed minimal design and taking into account the difference in the number of acquisitions. The ensuing microscopic fractional anisotropy (μFA) maps were compared over a range of b-values up to 5000 s/mm2. Noise robustness was studied using analytical calculations and numerical simulations. Results: The minimal protocol quantified μFA at an accuracy comparable to the estimates obtained via the more theoretically robust DDE 5-design. μFA's sensitivity to noise was found to strongly depend on compartment anisotropy and tensor magnitude in a non-linear fashion. When μFA < 0.75 or when mean diffusivity is particularly low, very high signal to noise ratio (SNR) is required for precise quantification of μFA. Conclusion: Our work supports using DDE for quantifying microscopic diffusion anisotropy in clinical settings but raises hitherto overlooked precision issues when measuring μFA with DDE and typical clinical SNR.

description: Let $L$ be the function field of a projective space ${\mathbb P}^n_k$ over an algebraically closed field $k$ of characteristic zero, and $H$ be the group of projective transformations. An $H$-sheaf ${\mathcal V}$ on ${\mathbb P}^n_k$ is a collection of isomorphisms ${\mathcal V} \longrightarrow g^{\ast}{\mathcal V}$ for each $g\in H$ satisfying the chain rule. We construct, for any $n>1$, a fully faithful functor from the category of finite-dimensional $L$-semi-linear representations of $H$ extendable to the semi-group ${\rm End}(L/k)$ to the category of coherent $H$-sheaves on ${\mathbb P}^n_k$. The paper is motivated by a study of admissible representations of the automorphism group $G$ of an algebraically closed extension of $k$ of countable transcendence degree undertaken in \cite{rep}. The semi-group ${\rm End}(L/k)$ is considered as a subquotient of $G$, hence the condition on extendability. In the appendix it is shown that, if $\tilde{H}$ is either $H$, or a bigger subgroup in the Cremona group (generated by $H$ and a standard involution), then any semi-linear $\tilde{H}$-representation of degree one is an integral $L$-tensor power of $\det_LΩ^1_{L/k}$. It is shown also that this bigger subgroup has no non-trivial representations of finite degree if $n>1$.

description: Abstract

Self-esteem is one of the most fundamental dimensions of the personality of human person, it is a discreet, intangible, complex phenomenon, of which we are not always aware. The aim of our study was to establish the profile of exhaustion and stress among a group of nurses at Idriss Hospital (in the case of patients with meningitis).  In total, nearly 600,000 students participated in this study. For middle school students, the Kingdom displays a score of 384 points (the average is 500 points), for maths, and remains among the last in the 2015 ranking, where it precedes South Africa (372) and Saudi Arabia (368), the last in the ranking. In science, same story: Morocco is below the expected average, with a score of 393 points (at secondary school). (Men, 2016). The results indicate that 39.62% of caregivers in the tested group, compared to 25.58% in the control group, exhibited a high level of emotional exhaustion. On the other hand, 41.51% of caregivers in the tested group, compared to 32.56% in the control group, exhibited a high level of depersonalization. However, women in the tested group showed a stress rate of 89.09% compared to 30.77% in the control group. The most influential factors are the health status of the nurses, along with their seniority and workload. Faced with this alarming situation, authorities must intensify their efforts to address this public health issue.

description: CREB binding protein (CBP) and its paralog E1A binding protein (p300) are related to the development of inflammatory diseases, cancers and other diseases, and have been potential targets for the treatment of human diseases. In this work, interaction mechanism of three small molecules E3T, E3H, and E3B with CBP was investigated by employing molecular dynamics (MD) simulations, principal component analysis (PCA), and molecular mechanics/generalized born surface area (MM-GBSA) method. The results indicate that inhibitor bindings cause the changes of movement modes and structural flexibility of CBP, and van der Waals interactions mostly drive associations of inhibitors with CBP. In the meantime, the results based on inhibitor-residue interactions not only show that eight residues of CBP can strongly interact with E3T, E3H and E3B but also verify that the CH-CH, CH-π, and π-π interactions are responsible for vital contributions in associations of E3T, E3H and E3B with CBP. In addition, the H-O radial distribution functions (RDFs) were computed to assess the stability of hydrogen bonding interactions between inhibitors and CBP, and the obtained information identifies several key hydrogen bonds playing key roles in bindings of E3T, E3H and E3B to CBP. Potential new inhibitors have been proposed.

description: The main focus of this review is on magnetically induced anions. Before discussing these new anionic states which exclusively exist in the presence of magnetic fields, we review in some detail the anionic physics without external field. For completeness, we also outline the properties of field-free existing anions when exposed to magnetic fields. The magnetically induced states constitute an infinite manifold assuming that the nucleus of the anion is infinitely heavy. At laboratory field strengths the corresponding binding energies show two different scaling properties belonging to the ground ($\propto B^2$) and the excited ($\propto B^3$) magnetically induced states. We provide a detailed discussion of the physics of the moving anion taking into account the coupling between the anionic centre of mass and its electronic degrees of freedom. A number of field-adapted techniques exploiting exact constants of motion and the adiabatic separation of motions are applied to simplify the Hamiltonian that describes the effective interaction between the centre of mass and the electronic degrees of freedom. Employing classical simulations the autodetachment process of the anions in the field is observed and a rich variety of spectral properties of moving anions is predicted: depending on the parameters, such as the mass and polarizability of the neutral system as well as the field strength, induced bound states, resonances and detaching states of the corresponding anions are to be expected. An outline of an {\it{ab initio}} quantum approach is provided that allows quantum dynamical investigations of the moving anion.

description: Rotaxanes can have topological isomers because of their mechanically interlocked axle and wheel components. Directional isomers are formed when the rotaxanes are constructed using an asymmetric axle and a three-dimensional non-symmetrical wheel. In this work, directional isomers of [2]rotaxanes were synthesised using lariat dibenzo-24-crown-8 ether as a non-symmetrical wheel component and a sec-ammonium salt axle. Control over the directional isomer ratio of [2]rotaxanes was achieved, as demonstrated by kinetic resolution via N-acetylation of the [2]rotaxanes.

description: We consider a $2 \times 2$ operator matrix ${\mathcal A}_μ,$ $μ>0$ related with the lattice systems describing two identical bosons and one particle, another nature in interactions, without conservation of the number of particles. We obtain an analogue of the Faddeev equation and its symmetric version for the eigenfunctions of ${\mathcal A}_μ$. We describe the new branches of the essential spectrum of ${\mathcal A}_μ$ via the spectrum of a family of generalized Friedrichs models. It is established that the essential spectrum of ${\mathcal A}_μ$ consists the union of at most three bounded closed intervals and their location is studied. For the critical value $μ_0$ of the coupling constant $μ$ we establish the existence of infinitely many eigenvalues, which are located in the both sides of the essential spectrum of ${\mathcal A}_μ$. In this case, an asymptotic formula for the discrete spectrum of ${\mathcal A}_μ$ is found.

description: We test the spectrum of string theory on AdS_5 x S^5 derived in hep-th/0305052 against that of single-trace gauge invariant operators in free N=4 super Yang-Mills theory. Masses of string excitations at critical tension are derived by extrapolating plane-wave frequencies at g_{YM}=0 down to finite J. On the SYM side, we present a systematic description of the spectrum of single-trace operators and its reduction to PSU(2,2|4) superconformal primaries via a refined Eratostenes' supersieve. We perform the comparison of the resulting SYM/string spectra of charges and multiplicities order by order in the conformal dimension Δup to Δ=10 and find perfect agreement. Interestingly, the SYM/string massive spectrum exhibits a hidden symmetry structure larger than expected, with bosonic subgroup SO(10,2) and thirty-two supercharges.

Subjects: Nutritional Status – Obesity – Primary School Student – Health – Khemisset- Morocco.

description: Abstract

Obesity and overweight are forms of malnutrition. It can occur from a very young age and have lifelong consequences. The objective of this study was to evaluate the relationship between nutritional status and obesity in primary school children from the province of Khemisset, Morocco. 210 primary school children including 90 boys and 120 girls aged 10 to 13 years were recruited from public primary schools from the province of khemisset. Anthropometric parameters (weight, height, body mass index) were measured. The data was collected using a questionnaire. The results showed that 17% of primary school children are overweight, compared to 7% with obesity. Weight, height, and weight z-score were significantly higher in boys than in girls. Most children do not consume dried fruits, legumes, olives and olive oil, tea, and juices. Most primary school children eat pasta, cakes, cookies and cakes. The prevalence of obesity and overweight among primary school children is high. Primary school children are at risk of developing obesity-related diseases that can persist into adolescence and adulthood. Several studies on nutritional status will be recommended in preschool children in Morocco.

description: This study estimates the potential energy available from livestock and poultry wastes in the northeastern United States for 1982, with projections for 1990. Anaerobic digestion of dairy cow, hog, and laying hen manures could have produced 16.9 billion cubic feet of methane gas in 1982, with little change for 1990. Direct burning of litter from broilers, turkeys, and pullets could have resulted in 8.9 trillion Btu's in 1982 and 10.3 trillion Btu's in 1990. The total potential farm value of biomass energy ranged from $166 to $255 million in 1982 and $289 million to $458 million in 1990.

description: The study of territorial varieties of English pronunciation explores the diverse ways in which English is pronounced across different regions, reflecting both historical developments and sociocultural influences. These regional variations encompass differences in vowel sounds, consonant articulation, stress patterns, and intonation. The article examines key features of various regional accents, such as Received Pronunciation (RP), General American (GA), and various British and American regional dialects. It highlights how factors such as geography, social class, and historical language contact have shaped the pronunciation of English over time. The study also considers the implications of these variations for language teaching, linguistic identity, and mutual intelligibility. Understanding territorial pronunciation varieties is essential for comprehending the rich diversity of English as a global language.

Keywords: territorial varieties, English pronunciation, regional accents, Received Pronunciation, General American, sociolinguistics, language variation, dialects, mutual intelligibility, linguistic identity.

description: Criteria for distillability, and the property of having a positive partial transpose, are introduced for states of general bipartite quantum systems. The framework is sufficiently general to include systems with an infinite number of degrees of freedom, including quantum fields. We show that a large number of states in relativistic quantum field theory, including the vacuum state and thermal equilibrium states, are distillable over subsystems separated by arbitrary spacelike distances. These results apply to any quantum field model. It will also be shown that these results can be generalized to quantum fields in curved spacetime, leading to the conclusion that there is a large number of quantum field states which are distillable over subsystems separated by an event horizon.

description: This study examines the experiences and impact COVID-19 has had on industry online learners. Exploring initially the term ‘industry learner’ and explaining the background to the design of the online modules the learners participated on. The design and delivery of this programme resulted in minimal impacts from the COVID-19 pandemic. The study explores qualitative reports of industry learners’ experiences, and these are analysed using thematic analysis. The findings suggest that the design principle of maximising social interaction, at peer to peer and peer to educator levels, resulted in an enhanced student experience. Group based interactions were recognised by learners as both an occasional source of friction, but also as a valuable proxy for industry leadership roles and workplace group dynamics. This highlights the complex enhancing and inhibiting nature of group-based learning. Implications for further optimisation of online and blended learning environments are explored and associated future research priorities are identified.

description: The EOLE Experiment is revisited to study turbulent processes in the lower stratosphere circulation from a Lagrangian viewpoint and resolve a discrepancy on the slope of the atmospheric energy spectrum between the work of Morel and Larcheveque (1974) and recent studies using aircraft data. Relative dispersion of balloon pairs is studied by calculating the Finite Scale Lyapunov Exponent, an exit time-based technique which is particularly efficient in cases where processes with different spatial scales are interfering. Our main result is to reconciliate the EOLE dataset with recent studies supporting a k^{-5/3} energy spectrum in the range 100-1000 km. Our results also show exponential separation at smaller scale, with characteristic time of order 1 day, and agree with the standard diffusion of about 10^7 m^2/s at large scales. A still open question is the origin of a k^{-5/3} spectrum in the mesoscale range, between 100 and 1000 km.

description: Drug delivery using metal-organic frameworks (MOF) has elicited interest in their biocompatibility; however, few studies have been conducted on their stability in common buffers, cell media, and blood proteins. In particular, the use of ZIF-8, a MOF interconnected by Zn and methylimidazole, has been frequently employed. In this study, we tested single crystals of ZIF-8 with common laboratory buffers, cell media, and serum, and noted several issues. Buffers containing phosphate and bicarbonate alter the appearance and composition of ZIF-8; however, these buffers do not appear to cause cargo to leak out even when the ZIF-8 itself is displaced by phosphates. On the other hand, serum dissolves ZIF-8, causing premature cargo release. Our results show that ZIF-8 undergoes surface chemistry changes that may affect the interpretation of cellular uptake and cargo release data. On the other hand, it provides a rational explanation as to how ZIF-8 neatly dissolves in vivo.

description: Abundant world rice supply has led to renewed interest in 4mproving quality of modern rice varieties. Implicit prices of ; graia. characteristics show that Philippine consumers prefer fewer broken grains and a soft cooked texture. Substantial consumer surplus gains would result from introduction of varieties with improved cooking quality. Breeding for better quality has an internal rate of return of 23. percent.

description: Let $W\in \mathbb{C}[x_1,\cdots,x_N]$ be an invertible polynomial with an isolated singularity at origin, and let $G\subset {\sf SL}_N\cap (\mathbb{C}^*)^N$ be a finite diagonal and special linear symmetry group of $W$. In this paper, we use the category ${\sf MF}_G(W)$ of $G$-equivariant matrix factorizations and its associated VSHS to construct a $G$-equivariant version of Saito's theory of primitive forms. We prove there exists a canonical categorical primitive form of ${\sf MF}_G(W)$ characterized by $G_W^{\sf max}$-equivariance. Conjecturally, this $G$-equivariant Saito theory is equivalent to the genus zero part of the FJRW theory under LG/LG mirror symmetry. In the marginal deformation direction, we verify this for the FJRW theory of $\big(\frac{1}{5}(x_1^5+\cdots+x_5^5),\mathbb{Z}/5\mathbb{Z}\big)$ with its mirror dual B-model Landau-Ginzburg orbifold $\big(\frac{1}{5}(x_1^5+\cdots+x_5^5), (\mathbb{Z}/5\mathbb{Z})^4\big)$. In the case of the Quintic family $\mathcal{W}=\frac{1}{5}(x_1^5+\cdots+x_5^5)-ψx_1x_2x_3x_4x_5$, we also prove a comparison result of B-model VSHS's conjectured by Ganatra-Perutz-Sheridan.

description: Generally, in any human field, a Smarandache Structure on a set A means a weak structure W on A such that there exists a proper subset B contained in A which is embedded with a stronger structure S. These types of structures occur in our everyday's life, that's why we study them in this book. Thus, as a particular case: A Near-ring is a non-empty set N together with two binary operations '+' and '.' such that (N, +) is a group (not necessarily abelian), (N, .) is a semigroup. For all a, b, c belonging to N we have (a + b) . c = a . c + b . c A Near-field is a non-empty set P together with two binary operations '+' and '.' such that (P, +) is a group (not-necessarily abelian), {P\{0}, .) is a group. For all a, b, c belonging to P we have (a + b) . c = a . c + b . c A Smarandache Near-ring is a near-ring N which has a proper subset P contained in N, where P is a near-field (with respect to the same binary operations on N).

description: In this article, we take a closer look at the reliability of large minimal networks constructed by repeated compositions of the simplest possible networks. For a given number of devices $n=2^m$ we define the set of all the possible compositions of series and parallel networks of two devices. We then define several partial orders over this set and study their properties. As far as we know the ranking problem has not been addressed before in this context, and this article establishes the first results in this direction. The usual approach when dealing with reliability of two-terminal networks is to determine existence or non-existence of uniformly most reliable networks. The problem of ranking two-terminal networks is thus more complex, but by restricting our study to the set of compositions we manage to determine and demonstrate the existence of a poset.
