description: We discuss under what circumstances a signal in upcoming laboratory searches for keV-scale sterile neutrinos would be compatible with those particles being a sizable part or all of dark matter. In the parameter space that will be experimentally accessible by KATRIN/TRISTAN, strong X-ray limits need to be relaxed and dark matter overproduction needs to be avoided. We discuss postponing the dark matter production to lower temperatures, a reduced sterile neutrino contribution to dark matter, and a reduction of the branching ratio in photons and active neutrinos through cancellation with a new physics diagram. Both the Dodelson-Widrow and the Shi-Fuller mechanisms for sterile neutrino dark matter production are considered. As a final exotic example, potential consequences of CPT violation are discussed.

description: Optical Brightening Agent (OBA) wastewater (OBAW) has been reported to be highly resistant to biodegradation. In this study, a real OBAW from an industry which was already treated using primary and secondary treatments (residual COD of secondary clarifier overflow (SCO): 3400–3700 mgL−1) was further treated by Fenton’s treatment (FT). Zahn-Wellens biodegradability test revealed that using small doses of H2O2 and Fe+2, the biodegradability of SCO improved to 90% as compared to ∼18% without FT. UV-Vis analysis revealed that ca. 80% of initially present OBAs were removed by treatment sequence outlined in this study. Biodegradability study on individual raw wastewaters from four types of OBAs (designated OBA-TS, OBA-DS-U, OBA-HS, and OBA-DS-D) being manufactured at the time of this study, revealed that OBA-TS wastewater was the most biodegradable (>95% biodegradability) followed by OBA-DS-U (∼60%), OBA-HS (∼20%), and OBA-DS-D (<5%). Application of FT improved the biodegradability of these streams as: OBA-DS-U (∼70%), OBA-HS (∼60%), and OBA-DS-D (∼50%). A treatment sequence consisting of waste coal dust (WCD) pretreatment-FT-biodegradation is a novel, economical, and sustainable approach to treating highly recalcitrant OBA wastewater.

description: Using PCA data from the Rossi X-Ray Timing Explorer (RXTE), we track the spectral states of the neutron star transient system Aql X-1 through a complete outburst cycle. We find a hard-to-soft state transition during the very early, rising phase of the outburst and show that there is a hysteresis effect such that the transition back to the hard state occurs at a luminosity $\sim $ 5 times {\it lower} than the hard-to-soft transition. This hysteresis effect rules out the propeller mechanism as the sole cause of state transitions in Aql X-1. Assuming the propeller mechanism only operates at a luminosity equal to or below that of the observed soft-to-hard transition requires that the magnetic field of Aql X-1 be less than $7\times 10^7$ Gauss, the lowest neutron star field known to date. To compare the state transition behavior of Aql X-1 with that found in transient black hole systems, we use RXTE ASM data to compute hardness-intensity diagrams for four black hole candidate transients where the ASM data should also give us state information throughout much of the outburst cycles. In all four systems, we find evidence for a hard-to-soft state transition during the rising outburst phase and for the source staying in a soft state down to much lower luminosities during the declining phase, i.e., a hysteresis effect. This similarity suggests a common origin for state transitions in low magnetic field neutron star and black hole systems, and the hysteresis effect rules out the ``Strong ADAF Principle'' for determining the state of an accretion disc. We discuss the general implications of these observations for current models of state transitions. We note the contrast to previous observations of the non-transient systems Cygnus X-1 and X-3 which do not show a hysteresis effect.

description: This research tries to answer three main questions: how important is agri-food sector for Croatian economy, why is Croatian agriculture uncompetitive compared to sectors in majority of the EU countries and what mechanisms of CAP could be used to improve agricultural competitiveness and sustain and develop rural life. Results show that agriculture and food processing industry are rather important for Croatian economy, contributing with more than 9% in the total GDP, with about 11% in total export and import and with more than 20% in total employment. However, within the EU context, agrifood sector is of little importance with a share of only about 1% in main economic indicators. Despite favourable natural resources, historical, organizational, economic and institutional reasons explain difficult situation in agriculture and in rural areas. Policy makers are trying to resolve these issues, now by available CAP mechanisms of income support and rural development. Despite considerable financial resources available for Croatian farmers, there is fear that the funds will not be adequately utilized. However, results of the previous research suggest that Croatian agriculture and food production still has a chance to survive and grow within European political and economic circumstances.

description: Although existing technology cannot yet directly produce fields at the Schwinger level, experimental facilities can already explore strong-field QED phenomena by taking advantage of the Lorentz boost of energetic electron beams. Recent studies show that QED cascades can create electron-positron pairs at sufficiently high density to exhibit collective plasma effects. Signatures of the collective pair plasma effects can appear in exquisite detail through plasma-induced frequency upshifts and chirps in the laser spectrum. Maximizing the magnitude of the QED plasma signature demands high pair density and low pair energy, which suits the configuration of colliding an over $10^{18}{Jm^{-3}}$ energy-density electron beam with a $10^{22}\mathrm{-}10^{23}{Wcm^{-2}}$ intensity laser pulse. The collision creates pairs that have a large plasma frequency, made even larger as they slow down or reverse direction due to both the radiation reaction and laser pressure. This paper explains at a tutorial level the key properties of the QED cascades and laser frequency upshift, and at the same time finds the minimum parameters that can be used to produce observable QED plasma.

description: In 2007-2008, a systematic survey, collection and arrangement was carried out for agricultural biological resources and traditional cultural knowledge of Hani People in 8 counties, 15 towns, and 23 village committees of Yunnan Province. A total of 299 samples were obtained about agricultural biological resources related to production and living of Hani People. According to purpose of utilization, samples were divided into grain crops, medicinal plants, vegetables, fruit trees, and oil crops, taking up 48.2%, 21.7%, 18.4%, 7.7%, and 2.0% of the samples respectively. The survey indicated that planting industry and breeding industry take up the dominant role in rural social economy of Hani People, so agricultural biological resources are the fundamental means of production maintaining rural social development of Hani People. The current situation of agricultural biological resources of Hani People in Yunnan, reasons for growth and decline were analyzed, and the utilization, protection and development of agricultural biological resources were discussed.

description: For quantum matter, eigenstate entanglement entropies obey an area law or log-area law at low energies and small subsystem sizes and cross over to volume laws for high energies and large subsystems. This transition is captured by crossover functions, which assume a universal scaling form in quantum critical regimes. We demonstrate this for the harmonic lattice model, which describes quantized lattice vibrations and is a regularization for free scalar field theories, modeling, e.g., spin-0 bosonic particles. In one dimension, the groundstate entanglement obeys a log-area law. For dimensions $d\geq 2$, it displays area laws, even at criticality. The distribution of excited-state entanglement entropies is found to be sharply peaked around subsystem entropies of corresponding thermodynamic ensembles in accordance with the eigenstate thermalization hypothesis. Numerically, we determine crossover scaling functions for the quantum critical regime of the model and do a large-deviation analysis. We show how infrared singularities of the system can be handled and how to access the thermodynamic limit using a perturbative trick for the covariance matrix. Eigenstates for quasi-free bosonic systems are not Gaussian. We resolve this problem by considering appropriate squeezed states instead. For these, entanglement entropies can be evaluated efficiently.

We construct new numerical techniques, based on cluster decomposition algorithms, to analyze the point defect configurations. We find that these criteria produce results for the Kosterlitz-Thouless temperature in agreement with a topological transition between a polarizable insulator and a conductor, at which free topological charges appear in the system. For global monopoles we find no pair unbinding transition. Instead a transition to a dense state where pairs are no longer distinguishable occurs at T3 are drawn, based on the observed behavior.

description: In this study, we investigate the potential of heavy quarkonia within a magnetized hot QGP medium having finite momentum anisotropy. The phenomenon of inverse magnetic catalysis is introduced into the system, influencing the magnetic field-modified Debye mass and thereby altering the effective quark masses. Concurrently, the impact of momentum anisotropy in the medium is considered that influence the particle distribution in the medium. The thermal decay width and dissociation temperature of quarkonium states, specifically the 1S and 2S states of charmonium and bottomonium, are computed. Our results reveal that both momentum anisotropy and the inverse magnetic catalysis effects play a significant role in modifying the thermal decay width and dissociation temperature of these heavy quarkonia states.

description: A charcoal-shaped catalyst NiFe2O4/Fe2O3 in electro-Fenton (EF) was synthesized by a facile precipitation approach via sintering products of oxalate co-precipitation. This obtained NiFe2O4/Fe2O3 catalyst was easily separated via an external magnetic field and was used as a heterogeneous electro-Fenton catalyst for rhodamine B (RhB, a target pollutant) degradation. Characteristics of NiFe2O4/Fe2O3 catalyst were assessed using scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Barrett-Emmett-Teller (BET), respectively. SEM results revealed that the proposed NiFe2O4/Fe2O3 was charcoal-shaped with the size in the range of 0.5–5 μm. Experiment results show that the EF process with the proposed catalyst could work in a wide pH range from 3 to 9. Under optimized conditions, estimated 90% RhB degradation was achieved in 60 min under the following conditions: 0.6 g/L NiFe2O4/Fe2O3, pH 3. Radical scavengers and electron spin resonance (ESR) spectra results demonstrated that the main oxidant species involved was ⋅OH, accounting for RhB degradation in EF. Moreover, according to our research on interfacial reaction, ⋅OH was mainly generated from the homogenous Fenton reaction rather than the surface Fenton reaction, stimulating by the dissolved Fe2+, Fe3+ and Ni2+ from catalyst. The reusability of NiFe2O4/Fe2O3 catalyst was evaluated for recycling the same catalyst for 5 runs. In conclusion, the facile fabrication NiFe2O4/Fe2O3 catalyst shows great potential in wastewater treatment with promising activity.

description: Processes of association in an atomic Bose-Einstein condensate, and dissociation of the resulting molecular condensate, due to Feshbach resonance in a time-dependent magnetic field, are analyzed incorporating non-mean-field quantum corrections and inelastic collisions. Calculations for the Na atomic condensate demonstrate that there exist optimal conditions under which about 80% of the atomic population can be converted to a relatively long-lived molecular condensate (with lifetimes of 10 ms and more). Entangled atoms in two-mode squeezed states (with noise reduction of about 30 dB) may also be formed by molecular dissociation. A gas of atoms in squeezed or entangled states can have applications in quantum computing, communications, and measurements.

description: In this paper we explore the capabilities of MoS2 and WS2 2D monolayers to produce radiation in the terahertz range by generation of high-order harmonics. This phenomenon, which is a result of the non-linear response of the electronic carrier population to the applied electric field, is studied by using a particle ensemble stochastic simulation approach based on the Monte Carlo method. The power of the produced harmonic signals is studied against the electric field amplitude, the external temperature, and the frequency of the excitation. Additionally, the stochastic nature of the simulation tool enables to discern the purely discrete harmonic signal from the background spectral noise that comes from the intrinsic carrier velocity fluctuations in the diffusive regime, permitting to set bandwidth thresholds for harmonic extraction. It was found that both TMDs showed similar thresholds bandwidths when compared to III-V semiconductor at low temperatures, while WS2 would be by far a better choice, over MoS2, for exploitation of the 7th and 9th harmonic generation.

description: Reclaimed water irrigation is one of the potential ways of solving the shortage of water resources, and the pollution risk on migration behavior of heavy metals in the soil which are irrigated by reclaimed water and the related soil surface is still short of research. Through the experimental study of different kinds of water irrigation methods on vegetable, it can be concluded that compared with sewage irrigation and tap water irrigation, reclaimed water irrigation does not pollute the soil, and it greatly saves the cost of water resources, and even provides a large number of growth elements for vegetables. The results show that after leaching by reclaimed water for 60 days, Cr, Cd, As, Hg, Pb, Ni, Zn and Cu from reclaimed water are enriched in soil to a certain degree, but with the leaching time extending, concentrations of the heavy metal remain stable. The variation of heavy metal content in soil irrigated by reclaimed water is small in vertical depth, basically showing a horizontal trend. According to Soil Environmental Quality Standards (GB15618-1995), soil irrigated by reclaimed water does not exceed the standard, better than soil quality standard of planting vegetables.

description: We propose a new approach to field theory on $κ$-Minkowski non-commutative space-time, a popular example of Lie-algebra space-time. Our proposal is essentially based on the introduction of a star product, a technique which is proving to be very fruitful in analogous studies of canonical non-commutative space-times, such as the ones recently found to play a role in the description of certain string-theory backgrounds. We find to be incorrect the expectation, previously reported in the literature, that the lack of symmetry of the $κ$-Poincare' coproduct should lead to interaction vertices that are not symmetric under exchanges of the momenta of identical particles entering the relevant processes. We show that in $κ$-Minkowski the coproduct and the star product must indeed treat momenta in a non-symmetric way, but the overall structure of interaction vertices is symmetric under exchange of identical particles. We also show that in $κ$-Minkowski field theories it is convenient to introduce the concepts of "planar" and "non-planar" Feynman loop-diagrams, again in close analogy with the corresponding concepts previously introduced in the study of field theories in canonical non-commutative space-times.

description: We suggest a geometrical mechanism for the ordering of slender filaments inside non-isotropic containers, using cortical microtubules in plant cells and packing of viral genetic material inside capsids as concrete examples. We show analytically how the shape of the cell affects the ordering of phantom, non-self-avoiding, stiff rods. We find that for oblate cells the preferred orientation is along the equator, while for prolate spheroids with an aspect ratio close to one, the orientation is along the principal (long axis). Surprisingly, at high enough aspect ratio, a configurational phase transition occurs, and the rods no longer point along the principal axis, but at an angle to it, due to high curvature at the poles. We discuss some of the possible effects of self avoidance, using energy considerations. These results are relevant to other packing problems as well, such as spooling of filament in the industry or spider silk inside water droplets.

description: Improper use of chemical fertilizers is an essential reason for diffused pollution of agriculture. Therefore, finding out influence factors of farmers in application of chemical fertilizers will play a significant role in controlling the diffused pollution of agriculture. Through field survey, a total of 340 samples in 4 counties of Chongqing Municipality were obtained. On the basis of these samples, an empirical study was carried out. The study results indicate that farmers’ application of chemical fertilizers is negatively correlated with farmers’ age, education level, male labor proportion, and soil fertility, while the annual family income, agricultural production population proportion, commodity trading characteristics, and scientific fertilizer application ability fail to pass the significance test. These results will provide reference for proper application of chemical fertilizers and controlling diffused pollution.

description: We explore the constant intensity cut method that is widely used for the derivation of the cosmic ray energy spectrum, for comparisons of data obtained at different atmospheric depths, for measuring average shower profiles, and for estimates of the proton-air cross section from extensive air shower data. The constant intensity cut method is based on the selection of air showers by charged particle or muon size and therefore is subject to intrinsic shower fluctuations. We demostrate that, depending on the selection method, shower fluctuations can strongly influence the characteristics of the selected showers. Furthermore, a mixture of different primaries in the cosmic ray flux complicates the interpretation of measurements based on the method of constant intensity cuts. As an example we consider data published by the Akeno Collaboration. The interpretation of the Akeno measurements suggests that more than 60-70% of cosmic ray primaries in the energy range 10^{16}-19^{17} eV are heavy nuclei. Our conclusions depend only weakly on the hadronic interaction model chosen to perform the simulations, namely SIBYLL and QGSjet.

description: We show that for any prime odd integer $d$, there exists a correlation of size $Θ(r)$ that can robustly self-test a maximally entangled state of dimension $4d-4$, where $r$ is the smallest multiplicative generator of $\mathbb{Z}_d^\ast$. The construction of the correlation uses the embedding procedure proposed by Slofstra (Forum of Mathematics, Pi. Vol. $7$, ($2019$)). Since there are infinitely many prime numbers whose smallest multiplicative generator is at most $5$ (M. Murty The Mathematical Intelligencer $10.4$ ($1988$)), our result implies that constant-sized correlations are sufficient for robust self-testing of maximally entangled states with unbounded local dimension.

description: Banana is an important tropical fruit and China is the world's third largest banana producer. The standardization level of banana industry not only affects the yield and quality of banana, but also plays an important role in promoting the production standardization and industrialization of other tropical crops. Through the analysis of revision, publicity and implementation of banana standard system in China as well as the study on its standard system and quality and safety standards, it is found that there are some problems such as irrational banana standard structure, short period of validity of standard, low level of quality and safety standards, and loose link between standards and production. At the same time, some recommendations are put forward in order to guide the standardized production and trade, research and management of banana and promote sustained, healthy and stable development of the banana industry in China.

description: We devise an algorithm which, given a bounded automaton A, decides whether the group generated by A is finite. The solution comes from a description of the infinite sequences having an infinite A-orbit using a deterministic finite-state acceptor. This acceptor can also be used to decide whether the bounded automaton acts level-transitively.

description: High Yield Genetically Modified Wheat (HOSUT) HOSUT lines are an innovation in wheat breeding based on biotechnology with an incremental yield potential of ca. 28% compared to conventional wheat varieties. We apply the real option concept of Maximum Incremental Social Tolerable Irreversible Costs (MISTICs) to do an ex-ante assessment of the socioeconomic potential of HOSUT lines for Germany. We analyze the cost and benefits to farmer and society within two scenarios. Our results of our scenario calculation indicate that not authorizing HOSUT lines is correct if German society values the possible total irreversible costs of this technology to be between €12.04 and €10.02 per citizen or more.

Subject B suffered from a diarrheal illness from days 151 to 159 of the study, during which he was culture-positive for Salmonella. The Enterobacteriaceae, the parent family of Salmonella, account for a median of 0.004 % of daily reads over the entire time series. During days 151 to 159, this family comprises a median of 10.1 % of each day’s reads and peaks at 29.3 % of reads on day 159. (PDF 104 kb)
2D MoS2 under switching field conditions: study of high-frequency noise from velocity fluctuations

description: The transient high-frequency noise response of two-dimensional MoS2 under abrupt large signal switching field conditions is studied by means of an ensemble Monte Carlo simulator. Low-to-high and high-to-low transitions are analyzed at low (77 K) and room temperature, considering several underlying substrates. The incorporation of stochastic individual scattering events allows capturing the transient collective phonon-electron coupling, which is shown to be responsible for the appearance of an oscillatory behaviour in the average velocity and energy at low temperature in the case of MoS2 on SiO2, hBN and Al2O3. Activation and deactivation of surface polar phonon emissions in the low-to-high field switching process yield to the appearance of a relevant peak in the power spectral density of velocity fluctuations in the THz range. The results show the important influence of the substrate type in the noise behaviour of MoS2 at very high frequencies, which is critical for the design of future FET devices based on 2D TMD technology.

description: The Corona virus pandemic is having a serious impact on the living conditions of the people who belong to the daily wage society. The impact of the death of the Corona virus on retail markets and other businesses is clearly visible in their banking transactions, but in the case of daily betting it is invisible because they spend what they earn and may not have an excess in their profits. Since the daily bets are in different categories, it is very difficult to find various problems with limited impact. This study reveals around the standard of living for daily wagers during the blocking period. The researcher risked collecting data from the largest daily bets in the village regions in the COVID-19. The researcher collected primary data from 800 salaried workers using simple random data collection techniques and analyzed the data using the simple percentage method. The present research is undertaken to study the impact of COVID-19 on the Daily wageworkers, considering the data which are secondary in nature, different appropriate statistical tools and techniques are applied for analysis and conclusion. On the basis of finding, recommendations are suggested to overcome these adverse situations in Chandrapur District of Maharashtra.

description: Gut microbiota shifts across travel. Plotted over time is the Jensen-Shannon Distance (JSD) between Subject A gut microbiota and the median gut microbial community when the subject lived in the United States. Subject A left the United States on day 70 and returned on day 122 (travel period shaded in gray); he suffered from diarrheal illnesses between days 80 and 85 and days 104 and 113 (red shading). The red dashed line denotes the median JSD between domestic gut microbiota samples and the median domestic gut microbiota. The JSD increase after arriving abroad, but before the first diarrheal illness (days 71 to 79) argues that travel abroad was sufficient to alter Subject Aâ s gut microbiota. The JSD declines below the red median JSD line on day 136, suggesting that recovery of gut microbiota from travel required 14Â days. (PDF 86 kb)
Which phase is measured in the mesoscopic Aharonov-Bohm interferometer?

description: Mesoscopic solid state Aharonov-Bohm interferometers have been used to measure the "intrinsic" phase, $α_{QD}$, of the resonant quantum transmission amplitude through a quantum dot (QD). For a two-terminal "closed" interferometer, which conserves the electron current, Onsager's relations require that the measured phase shift $β$ only "jumps" between 0 and $π$. Additional terminals open the interferometer but then $β$ depends on the details of the opening. Using a theoretical model, we present quantitative criteria (which can be tested experimentally) for $β$ to be equal to the desired $α_{QD}$: the "lossy" channels near the QD should have both a small transmission and a small reflection.
