description: Neutrino-nucleus cross sections for the detection of atmospheric neutrinos are calculated in relativistic impulse and random phase approximations. Pion production is estimated via inclusive Delta-hole nuclear excitations. The number of pion events can confuse the identification of the neutrino flavor. As a further source of pions we calculate coherent pion production (where the nucleus remains in the ground state). We examine how these nuclear structure effects influence atmospheric neutrino experiments and study possible improvements in the present detector simulations.

description: The Deliverable 5.1 reports and explains the database, which the SoilCare project developed and used for storing the monitoring results from the tested cropping systems and/or field agricultural experiments in the 16 Study sites. To properly monitor a cropping system and/or a field agricultural experiment a lot of information is required to capture all the possible interactions. The SoilCare WP5 devised a common data management system for all the study-sites. One important objective is to collect complete and comparable data for an analysis across study sites and data that allows any user to get all the required information when analysing a cropping system.The data model structure created based on the entity-relationship diagram and designed to capture all the possible dependencies and complex interactions in a cropping system. All information is grouped in different pools:
 i. (experiments’) Basic information such as institution and person metadata
 ii. (experimental) Field information like climate, inherent soil properties and spatial arrangement
 iii. The experimental setup which includes the details for the different treatments and the factors
 iv. Management data that includes all the detailed information for each group of management categories
 v. Results which include the measured data and metadata for the measurements/observations.

description: The transport of individual particles in inhomogeneous environments is complex and exhibits non-Markovian responses. The latter may be quantified by a memory function within the framework of the linear generalised Langevin equation (GLE). Here, we exemplify the implications of steady driving on the memory function of a colloidal model system for Brownian motion in a corrugated potential landscape, specifically, for one-dimensional motion in a sinusoidal potential. To this end, we consider the overdamped limit of the GLE, which is facilitated by separating the memory function into a singular (Markovian) and a regular (non-Markovian) part. Relying on exact solutions for the investigated model, we show that the random force entering the GLE must display a bias far from equilibrium, which corroborates a recent general prediction. Based on data for the mean-square displacement obtained from Brownian dynamics simulations, we estimate the memory function for different driving strengths and show that already moderate driving accelerates the decay of the memory function by several orders of magnitude in time. We find that the memory may persist on much longer timescales than expected from the convergence of the mean-square displacement to its long-time asymptote. Furthermore, the functional form of the memory function changes from a monotonic decay to a non-monotonic, damped oscillatory behaviour, which can be understood from a competition of confined motion and depinning. Our analysis of the simulation data further reveals a pronounced non-Gaussianity, which questions the Gaussian approximation of the random force entering the GLE.

description: We compute the Dirac spectral density of QCD in a wide range of eigenvalues by using a stochastic method. We use 2+1 flavor lattice ensembles generated with Mobius domain-wall fermion at three lattice spacings ($a=0.083, 0.055, 0.044$ fm) to estimate the continuum limit. The discretization effect can be minimized by a generalization of the valence domain-wall fermion. The spectral density at relatively high eigenvalues can be matched with perturbation theory. We compare the lattice results with the perturbative expansion available to $O(α_s^4)$.

description: Lobo Flat and Ryan Flat are the southern extent of the Salt Basin of Trans-Pecos Texas. The Salt Basin is a fault-bounded, northwest trending alluvial basin resulting from Basin-and-Range extension approximately 24 m.y.a. The study area covers approximately 700 square miles (1813 km²), is about 75 miles (120 km) long and ranges from 5 to 25 miles (8 to 40 km) wide. An unconfined aquifer occurs in the Cenozoic alluvial fill. The basin fill is absent at the margins of the basin, and thickens to over 1000 feet (305 m) near the center of the basin. It consists of sediments derived from the surrounding Wylie and Davis Mountains to the east, the Van Horn and Sierra Vieja Mountains to the west and the Oak Hills to the south. The alluvium consists of poorly-sorted coarse gravels and sands adjacent to the mountains, and grades into and is interlayered with silts and clays of the basin interior. The presence of interlayered finer-grained deposits and clay lenses results in localized semiconfined and perched water-table conditions. The groundwater is generally low in total dissolved solids, ranging from 128 mg/l to 1240 mg/l and is classified into three hydrochemical facies based on dominant ions. A Ca-HCO₃ water is found in a few wells near the margins of the basin and is similar to water found in the volcanic aquifers of the Davis Mountains. The dominant water type is a Na-HCO₃ water which occurs over the entire area. Several wells yield Na-SO₄ water high in total dissolved solids. The groundwater chemistry is controlled by the dissolution of calcium carbonate, gypsum, and by ion exchange processes as the groundwater moves along the flow path. The basin is through-flowing, with natural discharge occuring only by lateral flow to the north. Agricultural development of the Lobo area in the north part of the basin resulted in drawdown of the water table of up to 150 feet (45 m) between 1950 and 1980. Since about 1980, agricultural pumpage has decreased resulting in about 50 feet (15 m) of water table rebound. Recharge to the aquifer occurs primarily adjacent to the mountains in the alluvial fans. Results of 2-D computer modeling using MODFLOW and MODINV indicate a complex flow system influenced by the presence of clay lenses. Four hydraulic conductivity fields with a range of hydraulic conductivities from 1 ft/day (3.2 x 10⁻⁵ m/s) to 28 ft/day (9.9 x 10⁻⁵ m/s) were required to adequately simulate groundwater flow in the area

description: A field experiment was conducted at AICRP - WM, B. A. College of Agriculture, Anand Agricultural University, Anand during rabi 2019-20 and 2020-21 in lomy sand soils to study the correlation of the grain yield of maize on certain weed and crop parameters in middle Gujarat conditions. The experiment consisted ten treatments laid out in a randomized block design with three replications. After harvest, correlation and regression analysis were studied between grain yield as the dependent variable and each of the following traits as independent variables (Monocot weed density (no/m2) at 25, 50 DAS and at harvest, Dicot weed density (no/m2) at 25, 50 DAS and at harvest, Total weed density (no/m2) at 25, 50 DAS and at harvest, Monocot weed dry biomass (g/m2) at 25, 50 DAS and at harvest, Dicot weed dry biomass (g/m2) at 25, 50 DAS and at harvest, Total weed dry biomass (g/m2) at 25, 50 DAS and at harvest, Weed control efficiency at 25, 50 DAS and at harvest, Straw yield, Plant stand at 30 DAS and at harvest and Plant height at 30 DAS, 60 DAS and at harvest) The results revealed that grain yield was highly negatively correlated with density and dry biomass of weeds at 25and 50 DAS as well as at harvest in pooled analysis, while non-significant positive correlation was observed with weed control efficiency at 25 and 50 DAS but, highly significant positive correlation was found with weed control efficiency at harvest in pooled analysis. The correlation coefficient between grain yield and periodical plant height, straw yield and plant stand at harvest were highly significant positive correlation in pooled analysis, while plant stand at 30 DAS showed non-significant positive correlation.

description: In this paper, mean curvature type equations with general potentials and contact angle boundary conditions are considered.

We moreover provide alternative proofs for the higher-order estimates, and for the existence result.
Mirror, mirror : hegemonic framing of Malcolm X and Martin Luther King, Jr. in newspapers

description: This thesis explores how Malcolm X and Martin Luther King, Jr., were framed by the New York Times and the Washington Post from 1960 through 1965. Drawing on concepts of hegemony and ideology, along with racism and a fear of the Other, a textual analysis was used to examine 1,948 articles mentioning King and 307 articles mentioning Malcolm X. Coverage of each man was compared with the other for evidence of framing. The study found four recurring themes surrounding the coverage of these two men: the diminishment of Malcolm X as a leader, a mistrust and skepticism of Malcolm X and the Black Muslims, a deep fear of racial violence, and the stigmatization of Malcolm X. Through this framing, Malcolm X was labeled as a deviant while Martin Luther King, Jr., was embraced as a righteous leader. These characterizations reinforced hegemonic power structures while also supporting ideological notions of accepted ideologies in the United States
Type IIA on a Compact Calabi-Yau and D=11 Supergravity Uplift of its Orientifold

description: Using the prescription of [1] for defining period integrals in the Landau-Ginsburg theory for compact Calabi-Yau's, we obtain the Picard-Fuchs equation and the Meijer basis of solutions for the compact Calabi-Yau CY_3(3,243) expressed as a degree-24 Fermat hypersurface AFTER resolution of the orbifold singularities. This is similar in spirit to the method of obtaining Meijer basis of solutions in [2] for the case wherein one is away from the orbifold singularities, and one is considering the large-base limit of the Calabi-Yau. The importance of the method lies in the ease with which one can consider the large AND small complex structure limits, as well as the ability to get the "ln"-terms in the periods without having to parametrically differentiate infinite series. We consider in detail the evaluation of the monodromy matrix in the large and small complex structure limits. We also consider the action of the freely acting antiholomorphic involution of [2],[3] on D=11 supergravity compactified on CY_3(3,243) x S^1 [4] and obtain the Kaehler potential for the same in the limit of large volume of the Calabi-Yau. As a by-product, we also give a conjecture for the action of the orientation-reversing antiholomorphic involution on the periods, given its action on the cohomology, using a canonical (co)homology basis. Finally, we also consider showing a null superpotential on the orientifold of type IIA on CY_3(3,243), having taken care of the orbifold singularities, thereby completing the argument initiated in [2].

Photoionization Modelling of the Giant Broad-Line Region in NGC 3998

Publisher: name: arXiv
Year: 2017
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Prior high angular resolution spectroscopic observations of the Low-ionization nuclear emission-line region (Liner) in NGC 3998 obtained with the Space Telescope Imaging Spectrograph (STIS) aboard the Hubble Space Telescope (HST) revealed a rich UV-visible spectrum consisting of broad permitted and broad forbidden emission lines. The photoionization code XSTAR is employed together with reddening-insensitive emission line diagnostics to constrain a dynamical model for the broad-line region (BLR) in NGC 3998. The BLR is modelled as a large H$^+$ region ${\sim}$ 7 pc in radius consisting of dust-free, low density ${\sim}$ 10$^4$ cm$^{-3}$, low metallicity ${\sim}$ 0.01 $Z/Z_\odot$ gas. Modelling the shape of the broad H$α$ emission line significantly discriminates between two independent measures of the black hole mass, favouring the estimate of de Francesco et al. (2006). Interpreting the broad H$α$ emission line in terms of a steady-state spherically symmetric inflow leads to a mass inflow rate of 1.4 ${\times}$ 10$^{-2}$ M$_\odot$/yr, well within the present uncertainty of calculations that attempt to explain the observed X-ray emission in terms of an advection-dominated accretion flow (ADAF). Collectively, the model provides an explanation for the shape of the H$α$ emission line, the relative intensities and luminosities for the H Balmer, [O III], and potentially several of the broad UV emission lines, as well as refining the initial conditions needed for future modelling of the ADAF.

description: In this paper, we connect the following partial orders: majorization of vectors in linear algebra, majorization of functions in integration theory and the order of states of a physical system due to their temporal-causal connection.
 Each of these partial orders is based on two general inequalities for Markov operators and their adjoints. The first inequality compares pairs composed of a continuous function (observables) and a probability measure (statistical states), the second inequality compares pairs of probability measure. We propose two new definitions of majorization, related to these two inequalities. We derive several identities and inequalities illustrating these new definitions. They can be useful for the comparison of two measures if the Radon-Nikodym Theorem is not applicable.
 The problem is considered in a general setting, where probability measures are defined as convex combinations of the images of the points of a topological space (the physical state space) under the canonical embedding into its bidual. This approach allows to limit the necessary assumptions to functions and measures.
 In two appendices, the finite dimensional non-uniform distributed case is described, in detail. Here, majorization is connected with the comparison of general piecewise affine convex functions. Moreover, the existence of a Markov matrix, connecting two given majorizing pairs, is shown.

description: Detailed anisotropic (H$\parallel$ab and H$\parallel$c) resistivity and specific heat measurements were performed on online-grown YbPtIn and solution-grown YbPt$_{0.98}$In single crystals for temperatures down to 0.4 K, and fields up to 140 kG; H$\parallel$ab Hall resistivity was also measured on the YbPt$_{0.98}$In system for the same temperature and field ranges. All these measurements indicate that the small change in stoichiometry between the two compounds drastically affects their ordering temperatures (T$_{ord}\approx3.4$ K in YbPtIn, and $\sim2.2$ K in YbPt$_{0.98}$In). Furthermore, a field-induced quantum critical point is apparent in each of these heavy fermion systems, with the corresponding critical field values of YbPt$_{0.98}$In (H$^{ab}_c$ around 35-45 kG and H$^{c}_c\approx120$ kG) also reduced compared to the analogous values for YbPtIn (H$^{ab}_c\approx60$ kG and H$^{c}_c>140$ kG)

Catch Bonding in the Forced Dissociation of a Polymer Endpoint

Subjects: subject: Biological Physics (physics.bio-ph)

description: Applying a force to certain supramolecular bonds may initially stabilize them, manifested by a lower dissociation rate. We show that this behavior, known as catch bonding and by now broadly reported in numerous biophysics bonds, is generically expected when either or both the trapping potential and the force applied to the bond possess some degree of nonlinearity. We enumerate possible scenarios, and for each identify the possibility and, if applicable, the criterion for catch bonding to occur. The effect is robustly predicted by Kramers theory, Mean First Passage Time theory, and finally confirmed in direct MD simulation. Among the catch scenarios, one plays out essentially any time the force on the bond originates in a polymeric object, implying that some degree of catch bond behavior is to be expected in {\em any} protein-protein bond, as well as in more general settings relevant to polymer network mechanics or optical tweezer experiments.

This was an essentially interior estimate. In this paper, we provide a complement to the theory, proving a global curvature estimate for open surfaces that satisfy natural contact conditions at the intersection with a given boundary.

description: We examine the effect of isospin-violating meson-nucleon coupling constants and of $π$-$η$ mixing on the binding-energy differences of mirror nuclei in a model that possesses no contribution from $ρ$-$ω$ mixing. The ${}^{3}$He-${}^{3}$H binding-energy difference is computed in a nonrelativistic approach using a realistic wave function. We find the ${}^{3}$He-${}^{3}$H binding-energy difference very sensitive to the short-distance behavior of the nucleon-nucleon potential. We conclude that for the typically hard Bonn form factors such models can not account for the observed binding-energy difference in the three-nucleon system. For the medium-mass region (A=15--41) the binding-energy differences of mirror nuclei are computed using a relativistic mean-field approximation to the Walecka model. We obtain large binding-energy differences---of the order of several hundred keV---arising from the pseudoscalar sector. Two effects are primarily responsible for this new finding: a) the inclusion of isospin breaking in the pion-nucleon coupling constant, and b) the in-medium enhancement of the small components of the bound-state wave functions. We look for off-shell ambiguities in these results and find them to be large.

description: Jupiter’s ice-covered moon Europa is considered a prime target in the search for habitable worlds within our Solar System. Freezing at the ice-ocean interface (accretion) entrains material from the ocean, including salts and potential biosignatures. In this work, we first examine how accreted ice on Earth can be used to estimate the bulk composition of Europa’s ice shell through a review of published ice core data, sampling low temperature gradient environments. We find that ice forming beneath ice shelves can serve as a valid analog for ice accreting beneath the ice shells of Europa and Enceladus and that the mechanism of ice accretion (frazil vs. congelation) will serve as the primary factor governing the amount of salt entrained in the ice shell from the ocean. We then introduce a framework to model the brine, salt, and ice volume fraction for a given composition as a function of bulk salinity and temperature by translating the output of the aqueous geochemistry software to polynomial functions of temperature. Using this framework, we build models for two endmember (NaCl and MgSO₄) and two multi-ion “analog” endmember (chloride-dominated and sulfate-dominated) ice shell compositions. Motivated by the observation that a percolation threshold could ultimately govern the stable bulk salinity of a congelation ice shell, we use these models to study the efficiency of salt entrainment as a function of ocean salinity, composition, and the effective critical porosity, a new parameter introduced in this work. We find that the efficiency of salt entrainment in a congelation ice shell is minimally influenced by composition and ocean salinity and is ultimately governed by the effective critical porosity. Finally, we study the habitability of ice shell brine pockets and find that they are not geochemically prohibitive to life as we know it. Furthermore, we suggest that brine volume fraction, as a proxy for nutrient transport and recycling, may be a critical factor governing the habitability of Europa's ice shell and use it to define different classes of potential habitats within Europa’s ice shell.

description: Within an effective field theory framework we compute the most general structure of the one-loop corrections to the 4D gauge couplings in one- and two-dimensional orbifold compactifications with non-vanishing constant gauge background (Wilson lines). Although such models are non-renormalisable, we keep the analysis general by considering the one-loop corrections in three regularisation schemes: dimensional regularisation (DR), Zeta-function regularisation (ZR) and proper-time cut-off regularisation (PT). The relations among the results obtained in these schemes are carefully addressed. With minimal re-definitions of the parameters involved, the results obtained for the radiative corrections can be applied to most orbifold compactifications with one or two compact dimensions. The link with string theory is discussed. We mention a possible implication for the gauge couplings unification in such models.

The study applies statistical analysis and topic modelling to posts (tweets and retweets) published in Spanish on Twitter (n = 20,481 tweets) and to content identified as disinformation (n = 2,730) by two independent fact-checking projects in Spain from August 2019 to March 2020. The data reveal that the political communication strategy focuses primarily on the confrontation between the majority of political groups at the national level and on legitimizing the political projects of these groups to their potential voters through specific issues. The data also reveal a co-occurrence between messages published by political actors and content identified as disinformation by fact-checkers, which depends on the tweets’ political profile, virality, and sentimental load. For this reason, the digital presence of these actors creates favourable conditions for the viral dissemination of disinformation, mainly when their content focuses on mobilizing potential voters through emotional messages. It could be helpful for fact-checkers to identify and understand the role of these actors in promoting this content.

description: Regional seismic studies have found many small-scale scatterers with shear wave velocity (Vₛ) anomalies near subducting slabs in the lower mantle, indicating chemical anomalies at depth. Subducting slabs transport surface hydrated mid-ocean ridge basalt (MORB) into deep Earth, which is chemically and physically distinct from the surrounding mantle. Physical properties of MORB materials are thus important to understand observed seismic Vₛ anomalies. In this dissertation, physical properties of stishovite and CaCl₂-type post-stishovite, which are abundant MORB components, have been determined at high pressure in order to study geophysical consequences across the post-stishovite transition in MORB. Specifically, I measured sound velocities using Brillouin light scattering and impulsive stimulated light scattering, Raman shifts of optic modes using Raman spectroscopy, and atomistic properties using synchrotron single-crystal X-ray diffraction in diamond anvil cells at high pressure. Sound velocity results show that the elastic modulus C₁₂ of pure-endmember stishovite converges with C₁₁ at 55 GPa where the shear wave Vₛ₁ propagating along [110] direction becomes zero and aggregate shear wave Vₛ drops by ~26%. Microscopically, this abnormal elastic property can be correlated with a crossover of the apical and equatorial Si-O bond lengths that results in the occurrence of the symmetry-breaking spontaneous strain in the post-stishovite phase. Furthermore, the Al and H incorporation into stishovite lattice structure can significantly reduce transition pressure and slightly enhance Vₛ reduction. For example, stishovite with 1.3-2.1 mol % Al undergoes the ferroelastic transition at ~16-21 GPa where Vₛ drops by ~29%. This Al,H-dependent post-stishovite transition in subducted MORB materials has been used to explain depth-dependent small-scale seismic Vₛ anomalies beneath the Tonga subduction region. The coupled H and Al substitution, together with literature element partitioning data, indicates that stishovite with 1.3 mol% Al in the upper part of the lower mantle could accommodate ~0.3 wt% H₂O.

description: We consider an initial and boundary value problem invoked from the mathematical model for moisture transport in porous materials. Because of the difficulty appearing in the boundary condition, we have changed it and obtain the nonlinear parabolic equation with the nonlinear boundary condition in the one-dimensional interval. The main result of this paper is to prove existence and uniqueness of solutions to the problem by applying the standard fixed point theorem argument.

description: We report the detection of 1.3mm continuum and near-infrared K-band (2.2-micron) emission from the submillimeter galaxy SMM J00266+1708. Although this galaxy is among the brightest sub-mm sources detected in the blank-sky surveys (L~10^{13} L[sun]), SMM J00266+1708 had no reliable optical/near-infrared counter-part. We used sensitive interferometric 1.3mm observations with the Owens Valley Millimeter Array to accurately determine the position of the sub-mm galaxy. Follow-up near-infrared imaging with the Keck I telescope uncovered a new faint red galaxy at K=22.5 mag which is spatially coincident with the 1.3mm emission. This is currently the faintest confirmed counter-part of a sub-mm galaxy. Although the redshift of SMM J00266+1708 is still unknown, its high sub-mm/radio spectral index suggests that the system is at high redshift (z>2). Approximately 50% or more of the sub-mm galaxies are faint/red galaxies similar to that of SMM J00266+1708. These ultraluminous obscured galaxies account for a significant fraction of the total amount of star-formation at high redshift despite being missed by optical/ultraviolet surveys.

On a solar blowout jet: driven mechanism and the formation of cool and hot components

description: We present the observations of a blowout jet that experienced two distinct ejection stages. The first stage started from the emergence of a small positive magnetic polarity, which cancelled with the nearby negative magnetic field and caused the rising of a mini-filament and its confining loops. This further resulted in a small jet due to the magnetic reconnection between the rising confining loops and the overlying open field. The second ejection stage was mainly due to the successive removal of the confining field by the reconnection. Thus that the filament erupted and the erupting cool filament material directly combined with the hot jet originated form the reconnection region and therefore formed the cool and hot components of the blowout jet. During the two ejection stages, cool Hα jets are also observed cospatial with their coronal counterparts, but their appearance times are earlier than the hot coronal jets a few minutes. Therefore, the hot coronal jets are possibly caused by the heating of the cool Hα jets, or the rising of the reconnection height from chromosphere to the corona. The scenario that magnetic reconnection occurred between the confining loops and the overlying open loops are supported by many observational facts, including the bright patches on the both sides of the mini-filament, hot plasma blobs along the jet body, and periodic metric radio type III bursts at the very beginnings of the two stages. The evolution and characteristics of these features manifest the detailed non-linear process in the magnetic reconnection.

description: This study investigates the impact of age and income on the perceptions of quality of life, well-being, and policy awareness among senior citizens in Chhattisgarh. The results reveal that younger seniors (60-69 years) report higher quality of life due to better physical health, while older seniors (70+ years) exhibit greater well-being, likely due to increased psychological resilience. Income disparities significantly affect these perceptions, with higher income levels associated with better overall life satisfaction. However, the perceptions of policies, legal, and ethical aspects indicate that financial resources alone do not ensure positive outlooks in these areas. The findings underscore the need for age- and income-sensitive policies, promoting physical health and social engagement for younger seniors, and psychological support for older ones. Enhancing policy awareness through effective communication is crucial to improve the quality of life and well-being of senior citizens in Chhattisgarh.

description: The theoretical basis for this investigation is drawn mainly from the information processing theories of human problem solving developed by Newell and Simon with the addition of ideas from Bernard on mathematical problem solving. Using a clinical paradigm, a descriptive study is made of the processes used by high school students while solving geometry proofs. "Think aloud" protocols for student solutions to specific problems are analyzed extensively and individual solution sequences are tabulated. The individual solution sequences are used to construct an Empirical Problem Space and the applicability of the search representation and the heuristic search methods to geometry problem solving is investigated. Regular patterns of analysis, synthesis, and heuristic usage are indicated. Existing relationships between Analysis-Synthesis-Heuristic sequences, heuristic usage, problem solving efficiency, and total solution time are discussed. Indications of the effectiveness of the early introduction of goal oriented heuristics and of optimal heuristic usage were found. Comments regarding possible applications to instruction in geometry problem solving and suggestions for additional research are included

description: We numerically demonstrate a novel monolayer graphene-based perfect absorption multi-layer photonic structure by the mechanism of critical coupling with guided resonance, in which the absorption of graphene can significantly close to 99% at telecommunication wavelengths. The highly efficient absorption and spectral selectivity can be obtained with designing structural parameters in the near infrared ranges. Compared to previous works, we achieve the complete absorption of single-atomic-layer graphene in the perfect absorber for the first time, which not only opens up new methods of enhancing the light-graphene interaction, but also makes for practical applications in high-performance optoelectronic devices, such as modulators and sensors.
