description: This research work was conducted on economic feasibility of briquette made of coconut coir dust mixed with rice husk at different ratio. This study sought to assess the physical properties and calorific value of briquette and to establish the demand and willingness of potential users to substitute rice husk briquette and firewood. It was observed that briquette made from mixed coconut coir dust and rice husk at the ratio of 1:2 and 1:1 had desirable properties as compared to rice husk briquette. The percent of shatter indices, density, percent of resistance to water penetration, degree of densification and calorific value of briquette of mixing ratio 1:2 were found 99.75, 1.52gm/cc, 87.5, 11.35 and 4043 kcal/kg and of mixing ratio 1:1 were found 99.82, 1.48gm/cc, 87.5, 10.84 and 3657 kcal/kg, respectively. In case of rice husk briquette, the above values were 99.21, 1.40gm/cc, 75, 10.66 and 3537 kcal/kg, respectively. The production costs of mixing ratio 1:2 and 1: 1 were 3.27 Tk/kg and 3.10 Tk/kg, respectively which were lower than that of rice husk briquette. In partial budget, the substitution propositions among the selected briquettes indicated that coconut coir dust briquette of mixing ratio 1:1 appeared as the most impressive one.

description: In this paper, we present some new results on the geometrically m-step solvable Grothendieck conjecture in anabelian geometry. Specifically, we show the (weak bi-anabelian and strong bi-anabelian) geometrically m-step solvable Grothendieck conjecture(s) for affine hyperbolic curves over fields finitely generated over the prime field. First of all, we show the conjecture over finite fields. Next, we show the geometrically m-step solvable version of the Oda-Tamagawa good reduction criterion for hyperbolic curves. Finally, by using these two results, we show the conjecture over fields finitely generated over the prime field.

description: We fabricated spin-polarized surface electronic states with tunable Fermi level from semiconductor to low-dimensional metal in the Bi/GaSb(110)-(2$\times$1) surface using angle-resolved photoelectron spectroscopy (ARPES) and spin-resolved ARPES. The spin-polarized surface band of Bi/GaSb(110) exhibits quasi-one-dimensional character with the Rashba parameter $α_{\rm R}$ of 4.1 and 2.6 eVÅ\ at the $\barΓ$ and $\bar{\rm Y}$ points of the surface Brillouin zone, respectively. The Fermi level of the surface electronic state is tuned in situ by element-selective Ar-ion sputtering on the GaSb substrate. The giant Rashba-type spin splitting with switchable metallic/semiconducting character on semiconductor substrate makes this system a promising candidate for future researches in low-dimensional spintronic phenomena.

description: The efficiency of production of pork and its quality depends to a large extent on the enrichment of diets with the necessary amount of nutrient and biologically active substances. The latter are introduced into the rations of pigs in premixes and other feed additives. Which fully provide pigs with energy, protein, amino acids, minerals, micro and macroelements and vitamins. As a result, it is a great health of animals, the maximum intensity of their growth, a quick economic effect and excellent taste properties of meat. Studies have shown that enrichment of rations of young pigs by BWMD "Minactivitis" does not have a negative impact on the body and positively affects the slaughter indicators, the morphological composition of the mascara and the mass of the internal organs of animals. With the use of premixes "Intermix" in feeding pigs, slaughter quality improved, a slaughter yield increased, the mass of the operator with a decrease in fataging in carcasses. The latter were more full of meat, with a larger area of muscle age. Consequently, the quality of meat affects a lot of factors, among which the main is feeding. The balanced diet of young pigs gives the possibility of complete assimilation of nutrients of feed, body saturation with all the necessary vitamins, microand macroelements that affect the growth and development of young pigs, and improve their meat productivity.

description: Sustainable, safe and nutritious food productions are the major challenges for global food security which meets dietary needs and food preferences for an active and healthy life. The objectives of the study were to utilize homestead resources in scientific method for producing fresh vegetables and fruits over space and time and to meet up the food and nutritional security of the farmers. Household survey was carried out to ascertain livelihoods information of the selected farm households before intervention. The trial was conducted at six replications by the participatory approaches following vegetables production “Golapgonj Model”. Results revealed that a family consisting five members having small homestead area with some fruit trees could be capable of harnessing sufficient and diversified vegetables and fruit round the year by utilizing the all possible homestead nieces and management of fruit trees. Results also suggested that the farmers consumed lion share of their products that could meet up nutrition from various vegetables and fruits, some of them distributed a portion to relatives and neighbors and also sold a portion of them. The additional income generated by selling of surplus vegetables and fruits was generally utilized to purchase supplementary food items, in turn increase the diversification of the family’s diet. Interestingly, active participation of family members (especially women and children) in their homestead vegetable production activities was also ensured. Thus, all these might be lead to full utilization of both physical & other farm resource available in the farm & mobilize resources that increased food & nutritional security, income as well as improved their livelihoods as well.

description: Transformer-based machine learning models have become an essential tool for many natural language processing (NLP) tasks since the introduction of the method. A common objective of these projects is to classify text data. Classification models are often extended to a different topic and/or time period. In these situations, deciding how long a classification is suitable for and when it is worth re-training our model is difficult. This paper compares different approaches to fine-tune a BERT model for a long-running classification task. We use data from different periods to fine-tune our original BERT model, and we also measure how a second round of annotation could boost the classification quality. Our corpus contains over 8 million comments on COVID-19 vaccination in Hungary posted between September 2020 and December 2021. Our results show that the best solution is using all available unlabeled comments to fine-tune a model. It is not advisable to focus only on comments containing words that our model has not encountered before; a more efficient solution is randomly sample comments from the new period. Fine-tuning does not prevent the model from losing performance but merely slows it down. In a rapidly changing linguistic environment, it is not possible to maintain model performance without regularly annotating new text.

description: The health and safety hazards posed by worn crane lifting ropes mandate periodic inspection for damage. This task is time-consuming, prone to human error, halts operation, and may result in the premature disposal of ropes. Therefore, we propose using efficient deep learning and computer vision methods to automate the process of detecting damaged ropes. Specifically, we present a vision-based system for detecting damage in synthetic fiber rope images using lightweight convolutional neural networks. We develop a camera-based apparatus to photograph the lifting rope's surface, while in operation, and capture the progressive wear-and-tear as well as the more significant degradation in the rope's health state. Experts from Konecranes annotate the collected images in accordance with the rope's condition; normal or damaged. Then, we pre-process the images, systematically design a deep learning model, evaluate its detection and prediction performance, analyze its computational complexity, and compare it with various other models. Experimental results show the proposed model outperforms other similar techniques with 96.5% accuracy, 94.8% precision, 98.3% recall, 96.5% F1-score, and 99.3% AUC. Besides, they demonstrate the model's real-time operation, low memory footprint, robustness to various environmental and operational conditions, and adequacy for deployment in industrial applications such as lifting, mooring, towing, climbing, and sailing.

description: Ageratum conyzoides L. is a common weed in many tropical and subtropical countries including India. The present study aimed to evaluate the antitick potential using Adult Immersion Test (AIT) and variability of its phytoconstituents with the developed HPTLC method in germplasms collected from Eastern and Western Ghats of India. Percent tick mortality at 8% concentration ranged from 10.0 ± 0.2 to 85.0 ± 2.9. Precocene I content ranged from 0.0004% to 0.072%, Precocene II content varied from 0.001% to 0.035%, and Caryophyllene oxide content was found to range from 0.0001% to 0.0023% in crude drug. Precocene II was positively correlated (coefficient = 0.656) with tick mortality (%) in the germplasm collected from Western Ghats. However, in Eastern Ghat samples, Precocene I was positively correlated (coefficient = 0.550) with per cent tick mortality. There is significant variation in marker compound content as well as antitick activity of the extracts; however, a direct correlation among marker compounds and antitick activity was not observed. This indicates there may be some other phytomolecules responsible for antitick activity of the extract. This study will lead to a potential source of quality raw material for the industry in developing herbal acaricide.

description: The paper tests the hypothesis that cultural and social background is far more influential to form preferences about policy than the level of fact-based knowledge a person possesses. The data for the case study stem from a web-based survey among a representative sample of the adult population in Norway. The degree of knowledge of agriculture in this paper is operationalized through questions on five key characteristics of Norwegian agriculture that frequently arise in the public discussion. The results show that the amount of fact-based knowledge of agriculture to a very little extent explains differences within the sample. The cultural background of respondents is much more suited to explain agricultural policy preferences. Knowledge, however, shifts the attention from food price issues towards the delivery of public goods. The results allow us to hint at hot cognition as a possible explanation for such findings.

description: We report on a model built to predict links in a complex network of scientific concepts, in the context of the Science4Cast 2021 competition. We show that the network heavily favours linking nodes of high degree, indicating that new scientific connections are primarily made between popular concepts, which constitutes the main feature of our model. Besides this notion of popularity, we use a measure of similarity between nodes quantified by a normalized count of their common neighbours to improve the model. Finally, we show that the model can be further improved by considering a time-weighted adjacency matrix with both older and newer links having higher impact in the predictions, representing rooted concepts and state of the art research, respectively.

description: We consider parabolic flows on 3-dimensional manifolds which are renormalized by circle extensions of Anosov diffeormorphisms. This class of flows includes nilflows on the Heisenberg nilmanifold which are renormalized by partially hyperbolic automorphisms. The transfer operators associated to the renormalization maps, acting on anisotropic Sobolev spaces, are known to have good spectral properties (this relies on ideas which have some resemblance to representation theory but also apply to non-algebraic systems). The spectral information is used to describe the deviation of ergodic averages and solutions of the cohomological equation for the parabolic flow.

description: The heat capacity of pure ^3He in low density aerogel is measured at 22.5 bar. The superfluid response is simultaneously monitored with a torsional oscillator. A slightly rounded heat capacity peak, 65 mu K in width, is observed at the ^3He-aerogel superfluid transition, T_{ca}. Subtracting the bulk ^3He contribution, the heat capacity shows a Fermi-liquid form above T_{ca}. The heat capacity attributed to superfluid within the aerogel can be fit with a rounded BCS form, and accounts for 0.30 of the non-bulk fluid in the aerogel, indicating a substantial reduction in the superfluid order parameter consistent with earlier superfluid density measurements.

description: We propose a class of greedy algorithms for weighted sparse recovery by considering new loss function-based generalizations of Orthogonal Matching Pursuit (OMP). Given a (regularized) loss function, the proposed algorithms alternate the iterative construction of the signal support via greedy index selection and a signal update based on solving a local data-fitting problem restricted to the current support. We show that greedy selection rules associated with popular weighted sparsity-promoting loss functions admit explicitly computable and simple formulas. Specifically, we consider $ \ell^0 $- and $ \ell^1 $-based versions of the weighted LASSO (Least Absolute Shrinkage and Selection Operator), the Square-Root LASSO (SR-LASSO) and the Least Absolute Deviations LASSO (LAD-LASSO). Through numerical experiments on Gaussian compressive sensing and high-dimensional function approximation, we demonstrate the effectiveness of the proposed algorithms and empirically show that they inherit desirable characteristics from the corresponding loss functions, such as SR-LASSO's noise-blind optimal parameter tuning and LAD-LASSO's fault tolerance. In doing so, our study sheds new light on the connection between greedy sparse recovery and convex relaxation.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: There exist instances of dynamical systems possessing symmetry transformations of which the conserved Noether charges generating these symmetries feature an explicit time dependence in their functional representation over phase space. The generators of such symmetries certainly do not commute with the Hamiltonian, and yet these charges are conserved observables for the classical and quantised dynamics. Furthermore within the Hamiltonian formalism and in the case of global symmetries such charges may be gauged to allow for arbitrary time dependent symmetry transformations, simply by extending the Hamiltonian to include the Noether charges as first-class constraints. An explicit illustration of these issues is presented in a simple and most familiar model that applies also to the constant gravitational force. This note draws its primary motivation from the quest towards a theory for quantum gravity, in wanting to understand better the tension existing between the local Equivalence Principle of the gravitational interaction and the fundamental principles of Quantum Mechanics by considering the formulation of quantum systems relative to reference frames that are inertial or noninertial, and thus accelerated relative to one another through arbitrary time dependent spatial translations.

description: One-sided auctions are used for trading perishable agricultural commodities because their production cost is already "sunk." Moreover, the promptness and simplicity of onesided auctions are beneficial for trading in perishable commodities. However, sellers cannot participate in the price-making process in these auctions. A standard double auction market collects bids from both sides of traders and matches them to find the most efficient allocation, assuming that the value of unsold items remains unchanged. Nevertheless, in the market for perishable commodities, sellers suffer a loss when they fail to sell their commodities, because their salvage values are lost when the commodities perish without being sold. To solve this problem, we investigate the design of an online double auction for perishable commodities, where bids arrive dynamically with their time limits. Our market mechanism aims at improving the profitability of traders by reducing trade failures in the face of uncertainty of incoming/departing bids.

description: A Green's-function theory of antiferromagnetic short-range and long-range order (LRO) in the $S=1/2$ quasi-two-dimensional easy-plane XXZ model is presented. As the main new result, {\it two} phase transitions due to the combined influence of spatial and spin anisotropy are found, where below the higher and lower Néel temperature there occurs LRO in the transverse and in both the transverse and longitudinal spin correlators, respectively. Comparing the theory with neutron-scattering data for the correlation length of $\rm La_2CuO_4$, a very good agreement in the whole temperature dependence is obtained. Moreover, for $\rm La_2CuO_4$, $\rm Sr_2CuO_2Cl_2$, and $\rm Ca_{0.85}Sr_{0.15}CuO_2$ the second phase with longitudinal LRO is predicted to appear far below room temperature.

description: Treating electron correlation more accurately and efficiently is at the heart of the development of electronic structure methods. In the present work, we explore the use of stochastic approaches to evaluate high-order electron correlation energies, whose conventional computational scaling is unpleasantly steep, being $O(N^{n+3})$ with respect to the system size $N$ and the perturbation order $n$ for the Møller-Plesset (MP) series. To this end, starting from Goldstone's time-dependent formulation of \emph{ab initio} many-body perturbation theory (MBPT), we present a reformulation of MBPT, which naturally leads to an Monte Carlo scheme with $O(nN^2+n^2N+f(n))$ scaling at each step, where $f(n)$ is a function of $n$ depending on the specific numerical scheme. Proof-of-concept calculations demonstrate that the proposed quantum Monte Carlo algorithm successfully extends the previous Monte Carlo approaches for MP2 and MP3 to higher orders. Therefore, for the first time the Goldstone's time-dependent formulation is made useful numerically for electron correlation energies, not only being purely as a theoretical tool.

description: Strongly-correlated quantum many-body systems are difficult to study and simulate classically. We recently proposed a variational quantum eigensolver (VQE) based on the multiscale entanglement renormalization ansatz (MERA) with tensors constrained to certain Trotter circuits. Here, we determine the scaling of computation costs for various critical spin chains which substantiates a polynomial quantum advantage in comparison to classical MERA simulations based on exact energy gradients or variational Monte Carlo. Algorithmic phase diagrams suggest an even greater separation for higher-dimensional systems. Hence, the Trotterized MERA VQE is a promising route for the efficient investigation of strongly-correlated quantum many-body systems on quantum computers. Furthermore, we show how the convergence can be substantially improved by building up the MERA layer by layer in the initialization stage and by scanning through the phase diagram during optimization. For the Trotter circuits being composed of single-qubit and two-qubit rotations, it is experimentally advantageous to have small rotation angles. We find that the average angle amplitude can be reduced considerably with negligible effect on the energy accuracy. Benchmark simulations suggest that the structure of the Trotter circuits for the TMERA tensors is not decisive; in particular, brick-wall circuits and parallel random-pair circuits yield very similar energy accuracies.

description: We report a structural phase transition found at Ts = 200 K in a pyrochlore oxide Cd2Re2O7 which shows superconductivity at Tc = 1.0 K. X-ray diffractionexperiments indicate that the phase transition is of the second order, from a high-temperature phase with the ideal cubic pyrochlore structure (space group Fd-3m) to a low-temperature phase with another cubic structure (space group F-43m). It is accompanied by a dramatic change in the resistivity and magnetic susceptibility and thus must induce a significant change in the electronic structure of Cd2Re2O7.

description: In recent decades, many developing countries have moved from taxing their agricultural sector to subsidizing it, a phenomenon referred to as “overshooting”. Using Ghana and Uganda as case study countries, this study aims to contribute to explaining this phenomenon by examining the role of policy beliefs. The study is based on the Advocacy Coalition Framework and relies on discourse analysis as analytical method. In-depth interviews with policy actors in both countries served as empirical basis. A quantitative analysis of the transcripts was used to identify different discourse coalitions, and a qualitative analysis was conducted to examine the discourses and identify their underlying policy beliefs. The paper identified far-reaching differences in the agricultural policy beliefs between domestic policy makers and donors regarding the question: What does it actually take to develop small-holder agriculture? The evidence from this analysis highlights the role that divergent policy beliefs can play in influencing agricultural policy choices.

description: In a recent paper characters and superdimension formulas were investigated for the class of representations with Dynkin labels $[0,\ldots,0,p]$ of the Lie superalgebra $osp(m|n)$. Such representations are infinite-dimensional, and of relevance in supergravity theories provided their superdimension is finite. We have shown that the superdimension of such representations coincides with the dimension of a $so(m-n)$ representation. In the present contribution, we investigate how this $osp(m|n)\sim so(m-n)$ correspondence can be extended to the class of $osp(2m|2n)$ representations with Dynkin labels $[0,\ldots,0,q,p]$.

description: Purpose: To develop and evaluate an end-to-end deep learning pipeline for segmentation and analysis of cardiac magnetic resonance images to provide core-lab processing for a multi-centre registry of Fontan patients.
 Materials and Methods: This retrospective study used training (n = 175), validation (n = 25) and testing (n = 50) cardiac magnetic resonance image exams collected from 13 institutions in the UK, US and Canada. The data was used to train and evaluate a pipeline containing three deep-learning models. The pipeline's performance was assessed on the Dice and IoU score between the automated and reference standard manual segmentation. Cardiac function values were calculated from both the automated and manual segmentation and evaluated using Bland-Altman analysis and paired t-tests. The overall pipeline was further evaluated qualitatively on 475 unseen patient exams.
 Results: For the 50 testing dataset, the pipeline achieved a median Dice score of 0.91 (0.89-0.94) for end-diastolic volume, 0.86 (0.82-0.89) for end-systolic volume, and 0.74 (0.70-0.77) for myocardial mass. The deep learning-derived end-diastolic volume, end-systolic volume, myocardial mass, stroke volume and ejection fraction had no statistical difference compared to the same values derived from manual segmentation with p values all greater than 0.05. For the 475 unseen patient exams, the pipeline achieved 68% adequate segmentation in both systole and diastole, 26% needed minor adjustments in either systole or diastole, 5% needed major adjustments, and the cropping model only failed in 0.4%.
 Conclusion: Deep learning pipeline can provide standardised 'core-lab' segmentation for Fontan patients. This pipeline can now be applied to the >4500 cardiac magnetic resonance exams currently in the FORCE registry as well as any new patients that are recruited.

Chiral anomaly in non-relativistic systems: Berry curvature and chiral kinetic theory

description: Chiral anomaly and the novel quantum phenomena it induces have been widely studied for Dirac and Weyl fermions. In most typical cases, the Lorentz covariance is assumed and thus the linear dispersion relations are maintained. However, in realistic materials, such as Dirac and Weyl semimetals, the non-linear dispersion relations appear naturally. We develop a kinetic framework to study the chiral anomaly for Weyl fermions with non-linear dispersions by using the methods of Wigner function and semi-classical equations of motion. In this framework, the chiral anomaly is sourced by Berry monopoles in momentum space and could be enhanced or suppressed due to the windings around the Berry monopoles. Our results can help understand the chiral anomaly-induced transport phenomena in non-relativistic systems.

description: In this review, we introduce the notion of quantum nonclassicality of light, and the role of nonclassicality in optical quantum metrology. The first part of the paper focuses on defining and characterizing the notion of nonclassicality and how it may be quantified in radiation fields. Several prominent examples of nonclassical light is also discussed. The second part of the paper looks at quantum metrology through the lens of nonclassicality. We introduce key concepts such as the Quantum Fisher information, the Cram{é}r-Rao bound, the standard quantum limit and the Heisenberg limit, and discuss how nonclassical light may be exploited to beat classical limitations in high precision measurements. The discussion here will be largely theoretical, with some references to specific experimental implementations.
