description: COVID-19 kriz yönetiminin ilk aşamalarında ruh sağlığı bir öncelik olarak görülmemiştir. İlerleyen süreçlerde ve ancak nüfus genelinde stresin arttığına dair ilk ciddi belirtiler ortaya çıktıktan sonra dikkatler ruh sağlığına ilişkin sorunlara çevrilmiştir (örneğin daha yaygın depresyon, anksiyete, travma sonrası stres, daha yaygın intihar düşünceleri, artan ev içi şiddet). Artık kriz sona ermiş gibi görünse de krizin insanların psikolojik iyilik halleri üzerindeki etkisini ölçmek, değerlendirmek ve tespit etmek hala zor, ancak yan etkileri devam etmektedir. Ayrıca, ruh sağlığı sorunları öncelikle pandeminin bir sonucu olarak kabul edilmiştir. Ancak bu yaklaşım, krizden önce de var olan ve COVID-19’un nüfus genelindeki etkisini hafifletmede veya şiddetlendirmede rol oynayan faktörleri göz ardı etmektedir. Bu konuya ilişkin sistematik veri toplamak, hangi grupların neden ruh sağlığı sorunları geliştirme riski altında olduğuna dair içgörü sağlayacak ve gelecekte olası bir kriz durumunda, politika önlemlerinin farklı etkilerini öngörmeye yardımcı olacaktır. Ayrıca, veri toplanması, ruh sağlığı sorunlarının erken tespitini ve zamanında tedavisini kolaylaştırmak için Avrupa düzeyinde önleme odaklı bir yaklaşımın geliştirilmesine temel oluşturacaktır.

description: We show that the Coulomb drag effect exhibits saturation at small temperatures, when calculated to the third order in the interlayer interactions. The zero-temperature transresistance is inversely proportional to the third power of the dimensionless sheet conductance. The effect is therefore the strongest in low mobility samples. This behavior should be contrasted with the conventional (second order) prediction that the transresistance scales as a certain power of temperature and is almost mobility-independent. The result demonstrates that the zero-temperature drag is not an unambiguous signature of a strongly-coupled state in double-layer systems.

Phytoremediation Technology in Agriculture – A Review
Creators: name: Anjali Deshmukh1*, Dr C Anbalagan2
Publisher: name: trends in Agriculture Science
Year: 2024

description: With the advent of industrialization, urbanization, and population explosion, the productivity of agricultural land has taken a drastic toll. Heavy metal pollution and over-fertilization are some of the causes of the present condition of agricultural lands. The conventional methods to improve soil fertility are expensive and not eco-friendly. Hence, it is important that we lay more emphasis on greener and less expensive technologies such as phytoremediation. It is a process of utilizing a variety of plants to remediate contaminated water, soil, and air. Phytoremediation is an eco-friendly, economical, and effective method to reduce, and in some cases eradicate the harmful effects of heavy metal pollution in the environment. The objective of this review paper is to understand the concept of phytoremediation, its types, the plants used, and its significance in the field of agriculture.

A Hermite WENO reconstruction for fourth order temporal accurate schemes based on the GRP solver for hyperbolic conservation laws

description: This paper develops a new fifth order accurate Hermite WENO (HWENO) reconstruction method for hyperbolic conservation schemes in the framework of the two-stage fourth order accurate temporal discretization in [{\em J. Li and Z. Du, A two-stage fourth order time-accurate discretization {L}ax--{W}endroff type flow solvers, {I}. {H}yperbolic conservation laws, SIAM, J. Sci. Comput., 38 (2016), pp.~A3046--A3069}]. Instead of computing the first moment of the solution additionally in the conventional HWENO or DG approach, we can directly take the {\em interface values}, which are already available in the numerical flux construction using the generalized Riemann problem (GRP) solver, to approximate the first moment. The resulting scheme is fourth order temporal accurate by only invoking the HWENO reconstruction twice so that it becomes more compact. Numerical experiments show that such compactness makes significant impact on the resolution of nonlinear waves.
The Subleading Isgur-Wise Form Factor $ξ_3(v\cdot v')$ and its Implications for the Decays $\bar B\to D^{(*)}\ell\,\barν$

description: We calculate, in the framework of QCD sum rules and to next-to-leading order in perturbation theory, the universal function $ξ_3(v\cdot v')$ which appears at order $1/m_Q$ in the heavy quark expansion of meson weak decay form factors. We find that radiative corrections of order $α_s$ are very important. Over the kinematic range accessible in semileptonic decays, $ξ_3(v\cdot v')$ is proportional to the leading-order Isgur-Wise function $ξ(v\cdot v')$ to very good accuracy. Taking into account all sources of uncertainty, we estimate $ξ_3/ξ=(0.6\pm 0.2)$. This reduces the theoretical uncertainty in the extraction of $|\,V_{cb}|$ from $\bar B\to D\,\ell\, \barν$ transitions. A measurement of the form factor ratio $A_2/A_1$ in $\bar B\to D^*\ell\,\barν$ decays can be used to test our prediction.

description: Gigapan Voyage is a self-contained remotely-operable Gigapan capturing system that is being developed by the Intelligent Robotics Group at NASA Ames Research Center. Gigapan Voyage was primarily designed to be integrated onto Johnson Space Center’s Lunar Electric Rovers. While on the Lunar Electric Rover, Gigapan Voyage was used by scientists and astronauts during the 2009 and 2010 Desert RATS field tests. The overall objective of this “robotic reconnaissance experiment” was to improve NASA’s understanding of how pre-cursor robotic scouting could enhance planning capabilities and increase science return from human exploration missions.
The motivation behind Gigapan Voyage is to merge all the sub-components of the commercial GigaPan system into an all-in-one system that can capture, stitch, and display Gigapans in an automated way via a simple web interface. The Gigapan Voyage system enables NASA to quickly and easily add remote-controlled Gigapan capturing capability onto rovers with minimal integration effort.

description: In this paper we describe the use of gigapixel imagery at the Sanctuary of the Great Gods, an archaeological site
on the island of Samothrace, Greece. The Sanctuary was the home of a secret cult that was a particular favorite
of Macedonian royalty during the 4th and 3rd centuries BC. Despite the lack of any current structures remaining
erect, the dozen buildings are remarkably well preserved and are spectacular examples of classical Greek
architecture. We are employing a number of sophisticated advanced visualization tools, including a 3-D
reconstruction of the site, computer-animated fly-throughs, and an interactive map. We have undertaken a
topographic survey and are integrating georeferenced GigaPans into a geographic information system (GIS). This
system will allow us to return to the site in future years, capturing the same scene, thus better informing the
upcoming site management plan and allowing us to observe change over time.

description: The existence of a minimal measurable length as a characteristic length in the Planck scale is one of the main features of quantum gravity and has been widely explored in the context. Various different deformations of spacetime have been employed successfully for the purpose. However, polymer quantization approach is a relatively new and dynamic field towards the quantum gravity phenomenology, which emerges from the symmetric sector of the loop quantum gravity. In this article, we extend the standard ideas of polymer quantization to find a new and tighter bound on the polymer deformation parameter. Our protocol relies on an opto-mechanical experimental setup that was originally proposed in Ref.\cite{ref:Igor} to explore some interesting phenomena by embedding the minimal length into the standard canonical commutation relation. We extend this scheme to probe the \emph{polymer length} deformed canonical commutation relation of the center of mass mode of a mechanical oscillator with a mass around the Planck scale. The method utilizes the novelty of exchanging the relevant mechanical information with a high intensity optical pulse inside an optical cavity. We also demonstrate that our proposal is within the reach of the current technologies and, thus, it could uncover a decent realization of quantum gravitational phenomena thorough a simple table-top experiment.

description: Persistence modules are a central algebraic object arising in topological data analysis. The notion of interleaving provides a natural way to measure distances between persistence modules. We consider various classes of persistence modules, including many of those that have been previously studied, and describe the relationships between them. In the cases where these classes are sets, interleaving distance induces a topology. We undertake a systematic study the resulting topological spaces and their basic topological properties.

description: Background The value of a participatory approach to the generation of evidence for health and social services from a moral, methodological and policy level continues to gain recognition globally. Trust is a crucial mechanism in the participatory health research (PHR) process and is strongly influenced by context. However, gaps remain in conceptualising and operationalising trust over time in PHR partnerships. Objective This case study seeks to address these gaps by exploring the evolution of trust multidimensionally across two timepoints. Setting and participants Participants in a PHR project called the Public and Patient Involvement (PPI) Ignite Network in Ireland (n=57 (T1); n=56 (T2)) were invited to complete a network survey at two timepoints. The PPI Ignite Network had local and national partners. Network measures Several core social network measures were calculated at both timepoints to characterise the differences between trust dimensions and between local and national partners. Results Subtle changes were observed across most network measures over the two timepoints. While there was a slight decrease in the number of connections for each trust dimension throughout the PPI Ignite Network, connections that were consistently nominated in both timepoints increased slightly. Some trust dimensions, such as vulnerability and integrity, were more similar, while others, like integrity and shared values, visions and goals, differed greatly, where national partners consistently received more incoming connections compared with local partners. Conclusion These findings (1) provide empirical support for using social network analysis to operationalise trust comprehensively and multidimensionally over time in a participatory partnership, (2) offer nuanced insights into the trust development process within the PPI Ignite Network and (3) enhance our understanding of trust in the community-based participatory research model.

description: The use of MS-like renormalization schemes in QCD requires an implementation of nontrivial matching conditions across thresholds, a fact often overlooked in the literature. We shortly review the use of these matching conditions in QCD and check explicitly that the prediction for $α_s(M_Z)$, obtained by running the strong coupling constant from the $M_τ$ scale, does not substantially depend on the exact value of the matching point chosen in crossing the $b$-quark threshold when the appropriate matching conditions are taken into account.

Stability of Half-Quantum Vortices in Equal-Spin Pairing States of $^3$He

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Recent experiments on superfluid $^3$He in globally anisotropic aerogels have shown realization of the polar superfluid phase and of the half-quantum vortices (HQVs) in this phase upon rotation. To clarify why the HQVs, which had not been detected clearly in the A phase of the bulk liquid, have been realized in the polar phase, we theoretically examine the relative stability of a HQV-pair against a single phase vortex in both the bulk A-phase and the polar phase in an aerogel. By taking care of important roles of a higher order gradient term, which assists the stability of HQVs but has never been incorporated so far in the Ginzburg-Landau (GL) approach, we find that several consequences, including the extension of the polar phase at lower pressures in the phase diagram, facilitate realization of the HQVs there in contrast to the case of the A phase in a slab geometry.

description: Soil profile pits are a primary in situ tool in understanding soil genesis and structure. When considered in the context of the landforms that underlie them, and when seen as a small revelation of the ‘excited skin’ that gives rise to plant communities and land uses, profiles can deepen our appreciation of soil’s critical importance in landscape-level processes and sustainability. This paper discusses how gigapixel imaging can assist in visualizing soil profiles and their details online, remote from the site, for both pedagogical and research purposes. It also demonstrates how the GigaPan.org system can serve as a convenient and accessible clearinghouse for linked soil, geological, plant community, and spatial landscape data.

description: We derive new constraints on the Hubble function H(phi) and subsequently on the inflationary potential V(phi) from WMAP 3-year data combined with the Sloan Luminous Red Galaxy survey (SDSS-LRG), using a new methodology which appears to be more generic, conservative and model-independent than in most of the recent literature, since it depends neither on the slow-roll approximation, nor on any extrapolation scheme for the potential beyond the observable e-fold range, nor on additional assumptions about initial conditions for the inflaton velocity. This last feature represents the main improvement of this work, and is made possible by the reconstruction of H(phi) prior to V(phi). Our results only rely on the assumption that within the observable range, corresponding to ~ 10 e-folds, inflation is not interrupted and the function H(phi) is smooth enough for being Taylor-expanded at order one, two or three. We conclude that the variety of potentials allowed by the data is still large. However, it is clear that the first two slow-roll parameters are really small while the validity of the slow-roll expansion beyond them is not established.

description: The evolution of extragalactic radio sources has been a fundamental problem in the study of active galactic nuclei for many years. A standard evolutionary model has been created based on observations of a wide range of radio sources. In the general scenario of the evolution, the younger and smaller Gigahertz-Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) sources become large-scale FRI and FRII objects. However, a growing number of observations of low power radio sources suggests that the model cannot explain all their properties and there are still some aspects of the evolutionary path that remain unclear. There are indications, that some sources may be short-lived objects on timescales of $10^4$ - $10^5$ years. Those objects represent a new population of active galaxies. Here, we present the discovery of several radio transient sources on timescales of 5-20 years, largely associated with renewed AGN (Active Galactic Nucleus) activity. These changing-look AGNs possibly represent behaviour typical for many active galaxies.

description: This paper focuses on the question of how unconditional stability can be achieved via multistep ImEx schemes, in practice problems where both the implicit and explicit terms are allowed to be stiff. For a class of new ImEx multistep schemes that involve a free parameter, strategies are presented on how to choose the ImEx splitting and the time stepping parameter, so that unconditional stability is achieved under the smallest approximation errors. These strategies are based on recently developed stability concepts, which also provide novel insights into the limitations of existing semi-implicit backward differentiation formulas (SBDF). For instance, the new strategies enable higher order time stepping that is not otherwise possible with SBDF. With specific applications in nonlinear diffusion problems and incompressible channel flows, it is demonstrated how the unconditional stability property can be leveraged to efficiently solve stiff nonlinear or nonlocal problems without the need to solve nonlinear or nonlocal problems implicitly.

Estimating stand basal area from forest panoramas

Year: 2010
Subjects: subject: 80106 Image Processing
subject: FOS: Computer and information sciences

description: A common forest inventory technique involves making 360° visual scans within forests and selecting a sample of trees by assessing the horizontal angle subtended by their trunks. These samples allow quick and accurate estimates of forest stand basal area. All of the information required to complete such estimates can be obtained from high-resolution panoramic photographs of forest interiors. Stand basal area in an Alaskan birch forest was measured and the result compared to estimates of basal area made using a traditional Bitterlich visual scan in the field and an equivalent protocol performed on gigapixel images captured with a GigaPan imager. The image-based method has great precision and acceptable accuracy when tree trunks are not obscured by other trees or shrubs, when stitching is error free, and when adequate depth of field provides well focused images. This technique may have application using panoramas taken for other purposes, including historical photographs.

description: We re-analyze data on deep inelastic polarized lepton-nucleon scattering, with particular attention to testing the Bjorken sum rule and estimating the quark contributions to the nucleon spin. Since only structure function data at fixed $Q^2$ can be used to test sum rules, we use E142 asymmetry measurements and unpolarized structure function data to extract $g_1^n$ at fixed $Q^2$ = 2 GeV$^2$. When higher-twist effects, which are important at low $Q^2$, are included, both the E142 and SMC data are compatible with the Bjorken sum rule within one standard deviation. Assuming validity of the Bjorken sum rule, we estimate the quark contributions to the nucleon spin, finding that their total net contribution is small, with the strange quark contribution non-zero and negative. The quark spin content of the nucleon spin is in agreement with Skyrme model.

description: We present a comprehensive study of accretion activity in the most underdense environments in the universe, the voids, based on the SDSS DR2 data. Based on investigations of multiple void regions, we show that AGN's occurrence rate and properties differ from those in walls. AGN are more common in voids than in walls, but only among moderately luminous and massive galaxies (M_r < -20, log M_*/M_sun < 10.5), and this enhancement is more pronounced for the weakly accreting systems (i.e., L_[O III] < 10^39 erg/s). Void AGN hosted by moderately massive and luminous galaxies are accreting at equal or lower rates than their wall counterparts, show less obscuration than in walls, and similarly aged stellar populations. The very few void AGN in massive bright hosts accrete more strongly, are more obscured, and are associated with younger stellar emission than wall AGN. Thus, accretion strength is probably connected to the availability of fuel supply, and accretion and star-formation co-evolve and rely on the same source of fuel. Nearest neighbor statistics indicate that the weak accretion activity (LINER-like) is not influenced by the local environment. However, H IIs, Seyferts, and Transition objects prefer more grouped small scale structures, indicating that the rate at which galaxies interact with each other affects their activity. These trends support a potential H II -> Seyfert/Transition Object -> LINER evolutionary sequence that we show is apparent in many properties of actively line-emitting galaxies, in both voids and walls. The subtle differences between void and wall AGN might be explained by a longer, less disturbed duty cycle of these systems in voids.

description: We derive an exact formula for the boundary free energy of the open Heisenberg XXZ spin chain. We allow for arbitrary boundary magnetic fields, but assume zero bulk magnetization. The result is completely analogous to earlier formulas for the so-called $g$-function: it is expressed as a combination of single integrals and two simple Fredholm determinants. Our expressions can be evaluated easily using numerical algorithms with arbitrary precision. We demonstrate that the boundary free energy can show a wide variety of behaviour as a function of the temperature, depending on the anisotropy and the boundary fields. We also compute the low temperature limit of the boundary free energy, and reproduce the known results for the ground state boundary energy, including the case of non-diagonal fields.

description: This study presents a further step within the ongoing R&D activities for the redesign of the CERN's Antiproton Decelerator Production Target (AD-Target). A first scaled target prototype, constituted of a sliced core made of ten Ta rods -8 mm diameter, 16 mm length- embedded in a compressed expanded graphite (EG) matrix, inserted in a 44 mm diameter Ti-6Al-4V container, has been built and tested under proton beam impacts at the CERN's HiRadMat facility, in the so called HRMT-42 experiment. This prototype has been designed following the lessons learned from previous numerical and experimental works (HRMT-27 experiment) aiming at answering the open questions left in these studies. Velocity data recorded on-line at the target periphery during the HRMT-42 experiment is presented, showing features of its dynamic response to proton beam impacts. Furthermore, x-ray and neutron tomographies of the target prototype after irradiation have been performed. These non-destructive techniques show the extensive plastic deformation of the Ta core, but suggest that the EG matrix can adapt to such deformation, which is a positive result. The neutron tomography successfully revealed the internal state of the tantalum core, showing the appearance of voids of several hundreds of micrometers, in particular in the downstream rods of the core. The possible origin of such voids is discussed while future microstructure analysis after the target opening will try to clarify their nature.

description: High spin states in $^{103}$Ag were investigated with the Gammasphere array, using the $^{72}$Ge($^{35}$Cl,$2p2n$)$^{103}$Ag reaction at an incident beam energy of 135 MeV. A $ΔJ$=1 sequence with predominantly magnetic transitions and two nearly-degenerate $ΔJ=1$ doublet bands have been observed. The dipole band shows a decreasing trend in the $B(M1)$ strength as function of spin, a well established feature of magnetic bands. The nearly-degenerate band structures satisfy the three experimental signatures of chirality in the nuclei; however microscopic calculations are indicative of a magnetic phenomenon

description: Climate change requires forward-looking policy responses. Developing such responses can be challenging for governments and, therefore, specific long-term institutions have been proposed for overcoming short-termism. However, the impacts of such institutions have been underexplored. In this paper, we analyze the influence of a long-term institution, the Dutch Delta Programme, on local governments’ decisions. The paper results are based on an analysis of climate adaptation strategies, investment plans and adaptation projects and interviews with policymakers, across seven Dutch municipalities. Results indicate that while local adaptation strategies are largely forward looking, adaptation projects tend to focus on solving present-day issues. We found that the Delta Programme enabled local governments to make forward-looking decisions and policies, by: (1) providing knowledge about climate vulnerabilities, (2) creating a broader framing of the issue of climate change, and (3) providing guidance for developing local climate adaptation policies.
Singular Vectors and Topological Theories from Virasoro Constraints via the Kontsevich-Miwa Transform

description: We use the Kontsevich-Miwa transform to relate the different pictures describing matter coupled to topological gravity in two dimensions: topological theories, Virasoro constraints on integrable hierarchies, and a DDK-type formalism. With the help of the Kontsevich-Miwa transform, we solve the Virasoro constraints on the KP hierarchy in terms of minimal models dressed with a (free) Liouville-like scalar. The dressing prescription originates in a topological (twisted N=2) theory. The Virasoro constraints are thus related to essentially the N=2 null state decoupling equations. The N=2 generators are constructed out of matter, the `Liouville' scalar, and $c=-2$ ghosts. By a `dual' construction involving the reparametrization $c=-26$ ghosts, the DDK dressing prescription is reproduced from the N=2 symmetry. As a by-product we thus observe that there are two ways to dress arbitrary $d\leq1$ or $d\geq25$ matter theory, that allow its embedding into a topological theory. By th e Kontsevich-Miwa transform, which introduces an infinite set of `time' variables $t_r$, the equations ensuring the vanishing of correlators that involve BRST-exact primary states, factorize through the Virasoro generators expressed in terms of the $t_r$. The background charge of these Virasoro generators is determined by the topological central charge.

description: Protected areas (PAs) are established to conserve wildlife habitats and biodiversity. To this end, the Chinese central government has initiated a pioneering environmental planning and management policy known as the Ecological Conservation Redline (ECR). While the ecological benefits of ECR policy have been extensively evaluated, spatially explicit assessment of the ECR remains understudied. Here, we propose an element-function-structure framework for assessing the concurrence of ECR areas and ecological conservation hotspots to further outline priority areas for conservation. Results show that 67% of existing PAs are protected by ECR areas, while that of ecological corridors is only 11%. Regional variation in the ECR representativeness can be leveraged by deliberately protecting tailored ecological conservation hotspots in specific locations and stepping stones in ecological corridors. This study highlights the substantial space for ecological management to achieve the goals of ECR policy, and discourses on the co-production of knowledge from researchers and policy makers.
Theory for the conditioned spectral density of non-invariant random matrices

description: We develop a theoretical approach to compute the conditioned spectral density of $N \times N$ non-invariant random matrices in the limit $N \rightarrow \infty$. This large deviation observable, defined as the eigenvalue distribution conditioned to have a fixed fraction $k$ of eigenvalues smaller than $x \in \mathbb{R}$, provides the spectrum of random matrix samples that deviate atypically from the average behavior. We apply our theory to sparse random matrices and unveil strikingly new and generic properties, namely: (i) their conditioned spectral density has compact support; (ii) it does not experience any abrupt transition for $k$ around its typical value; (iii) its eigenvalues do not accumulate at $x$. Moreover, our work points towards other types of transitions in the conditioned spectral density for values of $k$ away from its typical value. These properties follow from the weak or absent eigenvalue repulsion in sparse ensembles and they are in sharp contrast to those displayed by classic or rotationally invariant random matrices. The exactness of our theoretical findings are confirmed through numerical diagonalization of finite random matrices.

description: We consider a class of models in which supersymmetry breaking is communicated dominantly via a U'(1) gauge interaction, which also helps solve the μproblem. Such models can emerge naturally in top-down constructions and are a version of split supersymmetry. The spectrum contains heavy sfermions, Higgsinos, exotics, and Z' ~ 10-100 TeV; light gauginos ~ 100-1000 GeV; a light Higgs ~ 140 GeV; and a light singlino. A specific set of U'(1) charges and exotics is analyzed, and we present five benchmark models. Implications for the gluino lifetime, cold dark matter, and the gravitino and neutrino masses are discussed.

description: Traditionally, GigaPan technology has been used to acquire high resolution panoramas of large scenes. While this
application is useful for many scientific pursuits, it excludes the macro and microscopic realms of scientific research. An
increasing number of scientific disciplines (biological, medical, and material science) require high spatial resolution imagery
but suffer from an insufficient lateral field of view. A mosaic of microscopic images solves this problem by capturing the
entire subject while maintaining a high spatial resolution. This paper explores the application of gigapixel imaging
technology to the macro, micro, and nano scales. We discuss the design and implementation of three different instrument
adaptations that enable automatic mosaic capture of images through optical microscopes, scanning electron microscopes, and
macrophotography. This includes a discussion of motion control, focus stacking, and image stitching. The resulting images
represent virtual, archival, and explorable specimens.
Ground State of 2D Quantum Gravity and Spectral Density of Random Matrices

description: We compute the exact spectral density of random matrices in the ground state of the quantum hamiltonian corresponding to the matrix model whose double scaling limit describes pure gravity in 2D. We show that the non-perturbative effects are very large and in certain cases dominate the semi-classical WKB contribution studied in the earlier literature. The physical observables in this model are the loop averages with respect to the spectral density. We compute their exact ground-state expectation values and show that they differ significantly from the values obtained in the WKB approximation. Unlike the alternative regularizations of the nonperturbative 2D quantum gravity, based on analytic continuation of the Painlevé transcendent, our solution shows no pathologies.
