description: Rice (cv. BRRI Dhan28) seed from two sources (Farmer and BADC) were collected and stored in 10 different types of indigenous storage containers viz., i) earthen jar (EJ), ii) coaltar coated EJ, iii) seed mixed with neem leaves (Azedirecta indica) in EJ, iv) seed mixed with Biskatali leaves (Polygonum hydropiper) in EJ, v) biscuit tin, vi) drum, vii) hessian bag (HB), viii) hessian bag with polythene cover, ix) dole and x) cowdung coated dole for four months in the laboratory of the department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh. The changes of some quality components of seed such as moisture content, germination, insect and pathogen attack, protein and starch contents were monitored at certain interval over 120 days of storage. Containers were characterized into three categories viz., easily permeable, permeable and almost impermeable. In case of almost impermeable containers like biscuit tin, drum and hessian bag with polythene cover, seed moisture increased significantly with the advancement of storage period but did not exceed desired level. Moisture percentage of the seeds of biscuit tin, drum and hessian bag with polythene cover was 12.78, 12.95 and 12.88 %, respectively. Germination percentage of seeds in all impermeable containers was above 80 %. Seed mortality was found to be positively correlated with moisture content and storage duration. Seed borne pathogens were associated along with the seed. Field fungi like Alternaria, Curvularia, Cladosporium though observed initially, but in the last pathological test Aspergillus sp., Penicillium sp. and Fusarium sp. were found predominantly. Insect attack was severe in easily permeable containers. Permeable containers containing the leaves of neem and biskatali restricted insect and fungal attack. Seed protein and starch content varied with storage period. Starch content of seed was 77 % at 60 days of storage and decreased to 75 % at 120 days of storage. Significant superiority of BADC seed over the farmers’ seed irrespective of all the parameters studied was noticed. The overall observation suggests that, biscuit tin and drum could be used for small scale storage and hessian bag with polythene cover for bulk storage of rice seed for a certain period.

description: Understanding inter-site mutual mode interaction in coupled physical systems is essential to comprehend large compound systems as this local interaction determines the successive multiple inter-site energy transfer efficiency. We demonstrate that only the non-Hermitian coupling can correctly account for the light transfer between two coupled optical cavities. We also reveal that the non-Hermitian coupling effect becomes much crucial as the system dimension gets smaller. Our results provide an important insight to deal with general coupled-devices in the quantum regime.

description: In the one-dimensional Anderson model the eigenstates are localized for arbitrarily small amounts of disorder. In contrast, the Harper model with its quasiperiodic potential shows a transition from extended to localized states. The difference between the two models becomes particularly apparent in phase space where Heisenberg's uncertainty relation imposes a finite resolution. Our analysis points to the relevance of the coupling between momentum eigenstates at weak potential strength for the delocalization of a quantum particle.

description: An experiment was carried out to assess the genetic diversity of advanced rice (Oryza sativa L.) breeding lines using three SSR markers viz., RM147, RM167 and RM215. Thirty T- aman advanced breeding lines at F9 generation along with 4 check varieties were assessed. All three primers showed polymorphism. A total of 29 alleles were detected among the rice genotypes with an average of 9.67 alleles per locus. Polymorphism information content (PIC) ranged from 0.47 to 0.88 with an average of 0.71. A dendrogram was constructed based on total microsatellite polymorphism and 34 genotypes were grouped into four major clusters at 0.36 similarity co-efficient differentiating the early maturing genotypes from the late maturing types. The information about the genetic diversity might be utilized in future breeding programs for developing rice varieties with much shorter growth duration. The results also suggested that microsatellite markers which are linked to genes or QTLs responsible for growth duration properties are suitable tools for marker assisted selection (MAS) to select the rice genotypes of shorter growth duration.

description: The persistence properties of a set of random walkers obeying the A+B -> 0 reaction, with equal initial density of particles and homogeneous initial conditions, is studied using two definitions of persistence. The probability, P(t), that an annihilation process has not occurred at a given site has the asymptotic form $P(t) -> const + t^{-θ}$, where $θ$ is the persistence exponent (``type I persistence''). We argue that, for a density of particles $ρ>> 1$, this non-trivial exponent is identical to that governing the persistence properties of the one-dimensional diffusion equation, where $θ\approx 0.1207$. In the case of an initially low density, $ρ_0 << 1$, we find $θ\approx 1/4$ asymptotically. The probability that a site remains unvisited by any random walker (``type II persistence'') is also investigated and found to decay with a stretched exponential form, $P(t) \sim \exp(-const ρ_0^{1/2}t^{1/4})$, provided $ρ_0 << 1$. A heuristic argument for this behavior, based on an exactly solvable toy model, is presented.

Theory of ARPES intensities from the CuO$_2$ plane

name: Eder, R.
Publisher: name: arXiv
Year: 2001
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We present a theory for the photon energy and polarization dependence of ARPES intensities from the CuO$_2$ plane in the framework of strong correlation models. We show that for electric field vector in the CuO$_2$ plane the `radiation characteristics' of the $O$ $2p_σ$ and $Cu$ $3d_{x^2-y^2}$ orbitals are strongly peaked along the CuO$_2$ plane, i.e. most photoelectrons are emitted at grazing angles. This suggests that surface states play an important role in the observed ARPES spectra, consistent with recent data from Sr$_2$CuCl$_2$O$_2$. We show that a combination of surface state dispersion and Fano resonance between surface state and the continuum of LEED-states may produce a precipitous drop in the observed photoelectron current as a function of in-plane momentum, which may well mimic a Fermi-surface crossing. This effect may explain the simultaneous `observation' of a hole-like and an electron-like Fermi surfaces in Bi2212 at different photon energies. We show that by suitable choice of photon polarization one can on one hand `focus' the radiation characteristics of the in-plane orbitals towards the detector and on the other hand make the interference between partial waves from different orbitals `more constructive'.

description: In this work, we consider a modification of the usual Branching Random Walk (BRW), where we give certain independent and identically distributed (i.i.d.) displacements to all the particles at the $n$-th generation, which may be different from the driving increment distribution. We call this process last progeny modified branching random walk (LPM-BRW). Depending on the value of a parameter, $θ$, we classify the model in three distinct cases, namely, the boundary case, below the boundary case, and above the boundary case. Under very minimal assumptions on the underlying point process of the increments, we show that at the boundary case, $θ=θ_0$, where $θ_0$ is a parameter value associated with the displacement point process, the maximum displacement converges to a limit after only an appropriate centering, which is of the form $c_1 n - c_2 \log n$. We give an explicit formula for the constants $c_1$ and $c_2$ and show that $c_1$ is exactly the same, while $c_2$ is $1/3$ of the corresponding constants of the usual BRW Aidekon (2013). We also characterize the limiting distribution. We further show that below the boundary, $θ< θ_0$, the logarithmic correction term is absent. For above the boundary case, $θ> θ_0$, the logarithmic correction term is exactly the same as that of the classical BRW. For $θ\leq θ_0$, we further derive Brunet-Derrida -type results of point process convergence of our LPM-BRW to a Poisson point process. Our proofs are based on a novel method of coupling the maximum displacement with a linear statistic associated with a more well-studied process in statistics, known as the smoothing transformation.

description: Systematic errors in the database of $np$ differential cross sections below 350 MeV are studied. By applying angle-dependent normalizations with the help of the energy-dependent Nijmegen partial-wave analysis PWA93 the $χ^2$-values of some seriously flawed data sets can be reduced significantly at the expense of a few degrees of freedom. It turns out that in these special cases the renormalized data sets can be made statistically acceptable such that they do not have to be discarded any longer in partial-wave analyses of the two-nucleon scattering data.

description: Quintessence models leading to a constant equation of state are studied in hyperbolic universes. General properties of the quintessence potentials V(phi) are discussed, and for some special cases also the exact analytic expressions for these potentials are derived. It is shown that the observed angular power spectrum of the cosmic microwave background (CMB) is in excellent agreement with some of the quintessence models even in cases with negative curvature. It is emphasized that due to a (w_phi, Omega_phi, Omega_c)-degeneracy a universe with negative spatial curvature cannot be excluded.

description: Significant research and regulatory efforts have focused on reducing operational emissions in new residential buildings. However, the consideration of broader life cycle greenhouse gas (GHG) emissions of these buildings has been limited in the context of India, due to insufficient publicly available data. Energy retrofitting is a conventional approach for reducing the operational emissions of building, however, the impacts of embodied and life cycle GHG emissions are rarely considered. In this research, a low-rise reinforced concrete residential building located in the temperate climatic zone of India is assessed to analyse the net life cycle GHG emission implications of 216 retrofitting scenarios, each resulting in a distinct retrofitted building model. Streamlined life cycle assessment, along with DesignBuilder for dynamic energy simulation, are used to quantify the life cycle GHG emission impacts of the adopted scenarios. A total of 213 retrofitting scenarios resulted in a net life cycle benefit, whereas 3 scenarios associated with combined strategies of fenestration weatherstripping, and roof insulation did not yield any life cycle GHG benefits when compared to the base building. This may help inform the development of targeted policies, and actions to more consciously improve India’s existing residential stock.

description: Few detailed investigations of stellar populations in passive galaxies beyond z~1 are based on deep spectroscopic observations, due to the difficulty in obtaining such data. We present a study of stellar populations, structure, and mass-to-light ratios of a large sample of bulge-dominated galaxies in the two z=1.27 clusters Lynx E and Lynx W, based on deep ground-based optical spectroscopy combined with imaging from Hubble Space Telescope. We find that Lynx E has a well-defined core of red passive galaxies, while Lynx W lacks such a core. If all the sample galaxies evolve similarly in size from z=1.27 to the present, the data allow only 0.1 dex size-growth at a fixed dynamical mass. However, to link the Lynx central galaxies to brightest cluster galaxies similar to those of low redshift clusters, the Lynx galaxies would have to grow by at least a factor five, possibly through major merging. The mass-to-light ratios and the Balmer absorption lines of the Lynx galaxies are consistent with passive evolution of the stellar populations from z=1.27 to the present and support ages of 1--3 Gyr. The galaxies in the outskirts of the clusters contain younger stellar populations than found in the cluster cores. However, when evolved passively to z~0 both populations are consistent with the observed populations in the Coma cluster galaxies. The bulge-dominated emission line galaxies in the clusters are dominated by stellar populations with sub-solar metallicities. Thus, additional enrichment of these is required to produce Coma-like stellar populations by z~0.

description: Observations suggest that our universe is spatially flat on the largest observable scales. Exactly six different compact orientable three-dimensional manifolds admit flat metrics. These six manifolds are therefore the most natural choices for building cosmological models based on the present observations. This paper briefly describes these six manifolds and the harmonic basis functions previously developed for representing arbitrary scalar fields on them. The principal focus of this paper is the development of new harmonics for representing arbitrary vector and second-rank tensor fields on these manifolds. These new harmonics are designed to be useful tools for analyzing the dynamics of electromagnetic and gravitational fields on these spaces.

description: Groundwater samples of shallow and deep tubewells were collected from the different villages of Bhaluka upazilla in Bangladesh to assess their quality status for drinking, irrigation and livestock consumption. Different parameters of waters were determined to evaluate the quality. All the waters were alkaline in nature and electrical conductivity classified the samples as “good” for irrigation, while the TDS categorized the samples “highest desirable” limit for drinking and “fresh water” for irrigation and were suitable for drinking, irrigation and livestock consumption. Chloride content rated 2 samples unsuitable for livestock consumption. The concentrations of Zn were within safe limit, but Fe and Mn contents rated almost all the samples unsuitable for drinking and livestock consumption.With respect to Cu concentration, 8 samples were found unsuitable for long- term irrigation on all types of soils. Out of 17 samples, 12 samples classified as “excellent”, 4 as “good” and 1 as “doubtful” for irrigation due to different level of B. Ca, Mg, Na, K and P quantities of all the samples were within safe limit. SAR and EC rated all the samples as “medium salinity” and “low alkalinity” class and hardness of most of the waters were “hard water” class for irrigation.

description: The experiment was carried out during the period of June to November 2013 at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh with a view to examine the yield performance of some transplant aman rice varieties as influenced by different levels of nitrogen. The experiment consisted of four varieties viz. BRRI dhan49, BRRI dhan52, BRRI dhan56, BRRI dhan57 and four levels of N viz. 0, 46, 60 and 75 kg ha-1. The experiment was laid out in a randomized complete block design with three replications. Variety, levels of N and their interactions exerted significant influence on yield contributing characters and yield of transplant aman rice. Among the varieties, BRRI dhan52 produced the tallest plant (117.20 cm), highest number of effective tillers hill-1 (11.28), grains panicle-1 (121.5) and 1000-grain weight (23.65 g) whereas the lowest values of these parameters were produced by BRRI dhan57. Highest grain yield (5.69 t ha-1) was obtained from BRRI dhan52 followed by BRRI dhan49 (5.15 t ha-1) and the lowest one (4.25 t ha-1) was obtained from BRRI dhan57. In case of N, the tallest plant (111.70 cm), highest number of total tillers hill-1 (12.34), grains panicle-1 (133.6), 1000-grain weight (24.55 g) and grain yield (5.64 t ha-1) were obtained from 75 kg N ha-1 and the lowest values were obtained from control. BRRI dhan52 fertilized with 75 kg N ha-1 showed best performance with respect to all the parameters studied. The overall results suggest that BRRI dhan52 should be fertilized with 75 kg N ha-1 for getting higher yield under the agro-climatic condition of BAU.

description: A method of switching a controlled-NOT gate in a solid-stae NMR quantum computer is presented. Qubits of I=1/2 nuclear spins are placed periodically along a quantum spin chain (1-D antiferromagnet) having a singlet ground state with a finite spin gap to the lowest excited state caused by some quantum effect. Irradiation of a microwave tuned to the spin gap energy excites a packet of triplet magnons at a specific part of the chain where control and target qubits are involved. The packet switches on the Suhl-Nakamura interaction between the qubits, which serves as a controlled NOT gate. The qubit initialization is achieved by a qubit initializer consisting of semiconducting sheets attached to the spin chain, where spin polarizations created by the optical pumping method in the semiconductors are transferred to the spin chain. The scheme allows us to separate the initialization process from the computation, so that one can optimize the computation part without being restricted by the initialization scheme, which provides us with a wide selection of materials for a quantum computer.

description: This Pyramid was developed in the course of a research paper focusing on why South African academics adopt OER or not. We understood that numerous factors shaped their choices, but it became apparent that some factors were "essential" to OER activity while others were merely "influential". To clarify which factors were required for any type of OER activity, we developed the OER Adoption Pyramid, which consolidates the factors into six hierarchically related categories: access, permission, awareness, capacity, availability and volition. Under these terms we can place numerous other sub-factors which emerge in the OER literature, such as quality, relevance, localisation, licensing, self-confidence, etc. Going from bottom to top, these categories move from factors that are largely externally defined to factors that are more personally determined. This pyramid reveals that, ultimately, only academics or institutions that possess all six of these attributes at the same time (even if in some modified or attenuated fashion) can engage in OER activity. If even one of these elements is missing, they cannot participate in OER activity.

description: This contribution analyzes the adoption of integrated and organic olive farming, and the likely impacts of the new CAP reform on diverse olive farming systems in Andalusia, Spain. We use statistical methods for the former and a Positive Mathematical Programming model calibrated with the neutral procedure for the latter. The PMP model compares the situation of the average olive farm in base year with its position in a simulated year using two policy scenarios. Results indicate that the new rules on green payment don’t incentive the adoption of sustainable systems, although they don’t prevent the development of these systems whose sustained growth seems to be largely independent from market circumstances and agricultural policies. An alternative policy advocating the implementation of green payment scheme in the olive sector would lead to a better redistribution of public support from less to more environmentally-friendly farming practices, contributing to enhance the CAP aids legitimacy.

description: Convolutional neural networks (CNNs) have recently been applied to predict or model fluid dynamics. However, mechanisms of CNNs for learning fluid dynamics are still not well understood, while such understanding is highly necessary to optimize the network or to reduce trial-and-errors during the network optmization. In the present study, a CNN to predict future three-dimensional unsteady wake flow using flow fields in the past occasions is developed. Mechanisms of the developed CNN for prediction of wake flow behind a circular cylinder are investigated in two flow regimes: the three-dimensional wake transition regime and the shear-layer transition regime. Feature maps in the CNN are visualized to compare flow structures which are extracted by the CNN from flow at the two flow regimes. In both flow regimes, feature maps are found to extract similar sets of flow structures such as braid shear-layers and shedding vortices. A Fourier analysis is conducted to investigate mechanisms of the CNN for predicting wake flow in flow regimes with different wave number characteristics. It is found that a convolution layer in the CNN integrates and transports wave number information from flow to predict the dynamics. Characteristics of the CNN for transporting input information including time histories of flow variables is analyzed by assessing contributions of each flow variable and time history to feature maps in the CNN. Structural similarities between feature maps in the CNN are calculated to reveal the number of feature maps that contain similar flow structures. By reducing the number of feature maps that contain similar flow structures, it is also able to successfully reduce the number of parameters to learn in the CNN by 85\% without affecting prediction performances.

description: The National Laboratory of Space Weather in Mexico (Laboratorio Nacional de ClimaEspacial: LANCE) coordinates instrumentation for monitoring the space-weatherimpact over Mexico. Two of these instruments are the Mexican Array Radio Telescope(MEXART) and Compound Astronomical Low frequency Low cost Instrument for Spectroscopy and Transportable Observatory(CALLISTO) station from the e-CALLISTO network (CALLMEX). Both instruments are located at the same facility(Coeneo Michoacan, Mexico) and share a spectral band centered at 140 MHz. In this work we show the capabilities of the e-CALLISTO network as support to identify a solar radio burst in the signal of the MEXART radiotelescope. We identify 75 solarradio bursts in the MEXART signal: five events of Type II and 70 of Type III between September 2015 and May 2019. The analysis of solar radio bursts in the MEXART signal provide us valuable information about the development of the radio event due their high sensitivity, time resolution, and isotropic response. For the case of Type III solar radio events, we identify three characteristic phases in the dynamical evolution ofthe signal at 140 MHz: a pre-phase, a main peak, a decay phase, and a post-event phase.A Morlet wave transform was done of MEXART signals in the Type III solar radiobusts; in their spectra it was identified a pine tree structure preceding the main event in the time series. These characteristics are not observable in the data from the e-Callistonetwork.

Dissipative particle dynamics for interacting systems

description: We introduce a dissipative particle dynamics scheme for the dynamics of non-ideal fluids. Given a free-energy density that determines the thermodynamics of the system, we derive consistent conservative forces. The use of these effective, density dependent forces reduces the local structure as compared to previously proposed models. This is an important feature in mesoscopic modeling, since it ensures a realistic length and time scale separation in coarse-grained models. We consider in detail the behavior of a van der Waals fluid and a binary mixture with a miscibility gap. We discuss the physical implications of having a single length scale characterizing the interaction range, in particular for the interfacial properties.

A comparative study of quaternionic rotational Dirac equation and its interpretation

description: In this study, we develop the generalized Dirac like four-momentum equation for rotating spin-half particles in four-dimensional quaternionic algebra. The generalized quaternionic Dirac equation consists the rotational energy and angular momentum of particle and anti-particle. Accordingly, we also discuss the four vector form of quaternionic relativistic mass, moment of inertia and rotational energy-momentum in Euclidean space-time. The quaternionic four angular momentum (i.e. the rotational analogy of four linear momentum) predicts the dual energy (rest mass energy and pure rotational energy) and dual momentum (linear like momentum and pure rotational momentum). Further, the solutions of quaternionic rotational Dirac energy-momentum are obtained by using one, two and four-component of quaternionic spinor. We also demonstrate the solutions of quaternionic plane wave equation which gives the rotational frequency and wave propagation vector of Dirac particles and anti-particles in terms of quaternionic form.

X-boson cumulant approach to the periodic Anderson model

description: The Periodic Anderson Model (PAM) can be studied in the infinite U limit by employing the Hubbard X operators to project out the unwanted states. We have already studied this problem employing the cumulant expansion with the hybridization as perturbation, but the probability conservation of the local states (completeness) is not usually satisfied when partial expansions like the Chain Approximation (CHA) are employed. Here we treat the problem by a technique inspired in the mean field approximation of Coleman's slave-bosons method, and we obtain a description that avoids the unwanted phase transition that appears in the mean-field slave-boson method both when the chemical potential is greater than the localized level Ef at low temperatures (T) and for all parameters at intermediate T.

description: Reliable deployment of machine learning models such as neural networks continues to be challenging due to several limitations. Some of the main shortcomings are the lack of interpretability and the lack of robustness against adversarial examples or out-of-distribution inputs. In this exploratory review, we explore the possibilities and limits of adversarial attacks for explainable machine learning models. First, we extend the notion of adversarial examples to fit in explainable machine learning scenarios, in which the inputs, the output classifications and the explanations of the model's decisions are assessed by humans. Next, we propose a comprehensive framework to study whether (and how) adversarial examples can be generated for explainable models under human assessment, introducing and illustrating novel attack paradigms. In particular, our framework considers a wide range of relevant yet often ignored factors such as the type of problem, the user expertise or the objective of the explanations, in order to identify the attack strategies that should be adopted in each scenario to successfully deceive the model (and the human). The intention of these contributions is to serve as a basis for a more rigorous and realistic study of adversarial examples in the field of explainable machine learning.

A nested sequence of inequivalent Rindler vacua : Universal Relic Thermality of Planckian origin

description: The Bogoliubov transformation connecting the standard inertial frame mode functions to the standard mode functions defined in the Rindler frame $R_0$, leads to the result that the inertial vacuum appears as a thermal state with temperature $T_0=a_0/2π$ where $a_0$ is the acceleration parameter of $R_0$. We construct an infinite family of nested Rindler-like coordinate systems $R_1, R_2, ...$ within the right Rindler wedge, with time coordinates $τ_1, τ_2, ...,$ and acceleration parameters $a_1, a_2, ...$ by shifting the origin along the inertial $x$-axis by amounts $\ell_1, \ell_2,\cdots$. We show that, apart from the inertial vacuum, the \textit{Rindler vacuum} of the frame $R_n$ also appears to be a thermal state in the frame $R_{n+1}$ with the temperature $a_{n+1}/2π$. \textit{In fact, the Rindler frame $R_{n+1}$ attributes to all the Rindler vacuum states of $R_1, R_2, ... R_n$, as well as to the inertial vacuum state, the same temperature $a_{n+1}/2π$.} We further show that our result is discontinuous in an essential way in the coordinate shift parameters. For a Rindler frame $R_i$, this thermality {\it turns on} with smallest non-zero $\ell_i$ allowed in the semiclassical framework and remains insensitive to $(\ell_i,a_{i-1})$ thereafter, indicating its universal Planckian origin. Similar structures can be introduced in the right wedge of any spacetime with bifurcate Killing horizon, like, for e.g., Schwarzschild spacetime. Apart from providing unsuppressed observables capturing Planck scale effects, these results have important implications for quantum gravity when flat spacetime is treated as the ground state of quantum gravity.
