description: We investigate the optical properties of the normal state of the infinite-layer La$_{1-x}$Sr$_x$NiO$_2$ using DFT+DMFT. We find a correlated metal which exhibits substantial transfer of spectral weight to high energies relative to the density functional theory. The correlations are not due to Mott physics, which would suppress the charge fluctuations and integrated optical spectral weight as we approach a putative insulating state. Instead we find the unusual situation, that the integrated optical spectral weight {\it decreases} with doping and {\it increases } with increasing temperature. We contrast this with the coherent component of the optical conductivity, which {\it decreases} with increasing temperature as a result of a coherence$-$incoherence crossover. Our optical studies support a picture of a Hund's metallic state, where dynamical orbital fluctuations are visible at intermediate energies, even if at low energies the Fermi surface has primarily $d_{x^2 - y^2}$ character and we propose a low-energy two-band model with atom centered $e_g$ states.

description: We present observations of SO and $\rm SO_2$ lines toward the shocked regions along the L1157 chemically rich outflow, taken in the context of the Seeds Of Life In Space IRAM-NOrthern Extended Millimeter Array Large Program, and supported by data from Submillimeter Array and IRAM-30 m telescope at 1.1--3.6 mm wavelengths. We simultaneously analyze, for the first time, all of the brightest shocks in the blueshifted lobe, namely, B0, B1, and B2. We found the following. (1) SO and $\rm SO_2$ may trace different gas, given that the large(-scale) velocity gradient analysis indicates for $\rm SO_2$ a volume density ($\rm 10^5\text{--}10^6\,cm^{-3}$) denser than that of the gas emitting in SO by a factor up to an order of magnitude. (2) Investigating the 0.1 pc scale field of view, we note a tentative gradient along the path of the precessing jet. More specifically, $\rm χ({SO/SO_2})$ decreases from the B0-B1 shocks to the older B2. (3) At a linear resolution of 500--1400 au, a tentative spatial displacement between the two emitting molecules is detected, with the SO peak closer (with respect to $\rm SO_2$) to the position where the recent jet is impinging on the B1 cavity wall. Our astrochemical modeling shows that the SO and $\rm SO_2$ abundances evolve on timescales less than about 1000 years. Furthermore, the modeling requires high abundances ($2\times10^{-6}$) of both $\rm H_2S/H$ and S/H injected in the gas phase due to the shock occurrence, so pre-frozen OCS only is not enough to reproduce our new observations.

description: Supernova (SN) 2004et is the eighth historical SN in the nearby spiral galaxy NGC 6946. Here we report on early photometric and spectroscopic monitoring of this object. SN 2004et is a Type II event, exhibiting a plateau in its light curves, but its spectral and color evolution appear to differ significantly from those of other, more normal Type II-plateau (II-P) SNe. We have analyzed Canada-France-Hawaii Telescope (CFHT) images of the host galaxy taken prior to the SN explosion, identifying a candidate progenitor for the SN. The star's absolute magnitude and intrinsic color imply that it was a yellow, rather than red, supergiant star, with an estimated zero-age main sequence mass of $15^{+5}_{-2} M_\odot$. Although this mass estimate is consistent with estimates and upper limits for the progenitors of other, more normal SNe II-P, the SN 2004et progenitor's unusual color could further imply a pre-explosion evolutionary history analogous to, but less extreme than, that for the progenitors of the peculiar Type II-P SN 1987A or the Type IIb SN 1993J. The identity of the progenitor candidate needs to be verified when the SN has significantly dimmed.

description: Supply chain management is a very dynamic operation research problem where one has to quickly adapt according to the changes perceived in environment in order to maximize the benefit or minimize the loss. Therefore we require a system which changes as per the changing requirements. Multi agent system technology in recent times has emerged as a possible way of efficient solution implementation for many such complex problems. Our research here focuses on building a Multi Agent System (MAS), which implements a modified version of Gravitational Search swarm intelligence Algorithm (GSA) to find out an optimal strategy in managing the demand supply chain. We target the grains distribution system among various centers of Food Corporation of India (FCI) as application domain. We assume centers with larger stocks as objects of greater mass and vice versa. Applying Newtonian law of gravity as suggested in GSA, larger objects attract objects of smaller mass towards itself, creating a virtual grain supply source. As heavier object sheds its mass by supplying some to the one in demand, it loses its gravitational pull and thus keeps the whole system of supply chain per-fectly in balance. The multi agent system helps in continuous updation of the whole system with the help of autonomous agents which react to the change in environment and act accordingly. This model also reduces the communication bottleneck to greater extents.

description: We present a multi-wavelength investigation of the radio galaxy population in the galaxy cluster MOO J1506+5137 at $z$=1.09$\pm$0.03, which in previous work we identified as having multiple complex radio sources. The combined dataset used in this work includes data from the Low-Frequency Array Two-metre Sky Survey (LoTSS), NSF's Karl G. Jansky Very Large Array (VLA), the Robert C. Byrd Green Bank Telescope (GBT), the Spitzer Space Telescope, and the Dark Energy Camera Legacy Survey (DECaLS). We find that there are five radio sources which are all located within 500 kpc ($\sim$1$^{\prime}$) of the cluster center and have radio luminosities $P_{\mathrm{1.4GHz}}$ > 1.6$\times$10$^{24}$ W Hz$^{-1}$. The typical host galaxies are among the highest stellar mass galaxies in the cluster. The exceptional radio activity among the massive galaxy population appears to be linked to the dynamical state of the cluster. The galaxy distribution suggests an ongoing merger, with a subgroup found to the northwest of the main cluster. Further, two of the five sources are classified as bent-tail sources with one being a potential wide-angle tail (WAT)/hybrid morphology radio source (HyMoRS) indicating a dynamic environment. The cluster also lies in a region of the mass-richness plane occupied by other merging clusters in the Massive and Distant Clusters of WISE Survey (MaDCoWS). The data suggest that during the merger phase radio activity can be dramatically enhanced, which would contribute to the observed trend of increased radio activity in clusters with increasing redshift.

Abstract:

Controlling the propagation of light in the form of surface modes on miniaturized platforms is crucial for multiple applications. For dielectric multilayers that sustain Bloch surface waves at their interface to an isotropic dielectric medium, a conventional approach to manipulate them exploits shallow surface topographies fabricated on top of the truncated stack. However, such structures typically exhibit low index contrasts, making it challenging to confine, steer, and guide the Bloch surface waves. Here, we theoretically and experimentally demonstrate a device for a Bloch surface wave platform that resonantly couples light from a cavity to a straight waveguide. The structure is designed using topology optimization in a 2D geometry under the effective index approximation. In particular, the cavity–waveguide coupling efficiency of the radiation emitted by an individual source in the cavity center is optimized. The cavity is experimentally found to exhibit a narrow resonant peak that can be tuned by scaling the structure. The waveguide is shown to guide only light that resonates in the cavity. Fully three-dimensional simulations of the entire device validate the experimental observations.
DETERMINANTS OF HOUSEHOLD ACCESS TO AND PARTICIPATION IN FORMAL AND INFORMAL CREDIT MARKETS IN MALAWI

description: The paper uses the concept of credit limit to analyze the determinants of household access to and participation in informal and formal credit markets in Malawi. Households are found to be credit constrained, on average, both in the formal and informal sectors; they borrow, on average, less than half of any increase in their credit lines. Furthermore, they are not discouraged in their participation and borrowing decisions by further increases in the formal interest rate and/or the transaction costs associated with getting formal credit. This suggests that getting access to credit is much more important than its cost for these households. Hence, credit policies should focus on making access easier rather than providing credit with subsidized interest rates. The composition of household assets is found to be much more important as a determinant of household access to formal credit than the total value of household assets or landholding size. In particular, a higher share of land and livestock in the total value of household assets is negatively correlated with access to formal credit. However, land remains a significant determinant of access to informal credit. Therefore, poor households whose assets consist mostly of land and livestock but who want to diversify into nonfarm income generation activities may be constrained by lack of capital. As informal loans are usually too small to help poor households start a viable nonfarm business, these households may be forced to rely on farming as the sole source of income, despite its unreliability because of the frequency of drought in Malawi. Finally, formal and informal credit are found to be imperfect substitutes. In particular, formal credit, whenever available, reduces but does not completely eliminate informal borrowing. This suggests that the two forms of credit fulfill different functions in the household’s intertemporal transfer of resources.

description: Early childhood nutrition is thought to be an important input into subsequent academic achievement. This paper investigates the nutrition-learning nexus using a unique longitudinal data set, which follows a large sample of Philippine children from birth until the end of their primary education. We find that malnourished children perform more poorly in school, even after correcting for the effects of unobserved heterogeneity both across and within households. Part of the advantage that well-nourished children enjoy arises from the fact that they enter school earlier and thus have more time to learn. The rest of their advantage appears to stem from greater learning productivity per year of schooling rather than from greater learning effort in the form of homework time, school attendance, and so forth. Despite these findings, our analysis suggests that the relationship between nutrition and learning is not likely to be of overriding importance either for nutrition policy or in accounting for economic growth.

description: The usage of linear transformations has great relevance for data decorrelation applications, like image and video compression. In that sense, the discrete Tchebichef transform (DTT) possesses useful coding and decorrelation properties. The DTT transform kernel does not depend on the input data and fast algorithms can be developed to real time applications. However, the DTT fast algorithm presented in literature possess high computational complexity. In this work, we introduce a new low-complexity approximation for the DTT. The fast algorithm of the proposed transform is multiplication-free and requires a reduced number of additions and bit-shifting operations. Image and video compression simulations in popular standards shows good performance of the proposed transform. Regarding hardware resource consumption for FPGA shows 43.1% reduction of configurable logic blocks and ASIC place and route realization shows 57.7% reduction in the area-time figure when compared with the 2-D version of the exact DTT.

description: We investigate the star formation threshold in NGC 6822, a nearby Local Group dwarf galaxy, on sub-kpc scales using high-resolution, wide-field, deep HI, Halpha and optical data. In a study of the HI velocity profiles we identify a cool and warm neutral component in the Interstellar Medium of NGC 6822. We show that the velocity dispersion of the cool component (~4 km/s) when used with a Toomre-Q criterion gives an optimal description of ongoing star formation in NGC 6822, superior to that using the more conventional dispersion value of 6 km/s. However, a simple constant surface density criterion for star formation gives an equally superior description. We also investigate the two-dimensional distribution of Q and the star formation threshold and find that these results also hold locally. The range in gas density in NGC 6822 is much larger than the range in critical density, and we argue that the conditions for star formation in NGC 6822 are fully driven by this density criterion. Star formation is local, and in NGC 6822 global rotational or shear parameters are apparently not important.

Application of the dynamic one-dimensional model to pulp and paper mill wastewater clarifiers

Year: 2009

description: This thesis reports the results of research to calibrate the parameters of the Takacs model for pulp and paper sludge and to identify how the Takacs model works on pulp and paper wastewater clarifiers, as compared with municipal wastewater clarifiers. This research work involved zone settling tests for calibration of the model parameters, pilot scale tests and full scale clarifier simulations. The estimated parameter values for the pulp and paper (P&P) and municipal sludge are summarized in Table 1. Both the pulp and paper primary and secondary sludge can be simulated by the Takacs model under normal operating conditions. [Table 1 Diagram] Four clarifiers at the pulp and paper and municipal wastewater treatment plants were simulated. The results showed that all of the circular clarifiers could be simulated by this model, but the rectangular settling tank of this study required 2 or 3-dimensional modeling for a proper simulation. The waste sludge from both the primary and secondary clarifiers of the pulp and paper mill was about 1% higher in concentration than in the simulated result due to the fact that the sludge hoppers provide a long detention time for sludge thickening. Application of the calibrated Takacs model, however, can be of assistance in the design of new clarifiers. It can also be beneficial in operation assistance and risk management assessment for wastewater treatment plants. However, since the sludge at different treatment plants is specific and unique to each plant, the sludge in different situations may have different characteristics and therefore should be calibrated separately.

description: The concept of a C-class of differential equations goes back to E. Cartan with the upshot that generic equations in a C-class can be solved without integration. While Cartan's definition was in terms of differential invariants being first integrals, all results exhibiting C-classes that we are aware of are based on the fact that a canonical Cartan geometry associated to the equations in the class descends to the space of solutions. For sufficiently low orders, these geometries belong to the class of parabolic geometries and the results follow from the general characterization of geometries descending to a twistor space.
 In this article we answer the question of whether a canonical Cartan geometry descends to the space of solutions in the case of scalar ODEs of order at least four and of systems of ODEs of order at least three. As in the lower order cases, this is characterized by the vanishing of the generalized Wilczynski invariants, which are defined via the linearization at a solution. The canonical Cartan geometries (which are not parabolic geometries) are a slight variation of those available in the literature based on a recent general construction. All the verifications needed to apply this construction for the classes of ODEs we study are carried out in the article, which thus also provides a complete alternative proof for the existence of canonical Cartan connections associated to higher order (systems of) ODEs.

description: We present a new planetary nebula, first identified in images from the Australia Telescope Compact Array, although not recognized at that time. Recent observations with the Spitzer Space Telescope during the GLIMPSE Legacy program have rediscovered the object. The high-resolution radio and infrared images enable the identification of the central star or its wind, the recognition of the radio emission as thermal, and the probable presence of polycylic aromatic hydrocarbons in and around the source. These lead to the conclusion that G313.3+00.3 is a planetary nebula. This object is of particular interest because it was discovered solely through radio and mid-infrared imaging, without any optical (or near-infrared) confirmation, and acts as a proof of concept for the discovery of many more highly extinguished planetary nebulae. G313.3+00.3 is well-resolved by both the instruments with which it was identified, and suffers extreme reddening due to its location in the Scutum-Crux spiral arm.

description: We study the generalized version of energy-momentum squared gravity (EMSG) in the Palatini formalism. This theory allows the existence of a scalar constructed with energy-momentum tensor as $T_{αβ}T^{αβ}$ in the generic action of the theory. We study the most general form of this theory in the Palatini framework and present the underlying field equations. The equations of motion of a massive test particle have been derived. The weak field limit of the theory is explored and the generalized version of the Poisson equation is obtained. Moreover, we explore the cosmological behavior of the theory with emphasis on bouncing solutions. Some new bouncing solutions for the specific Palatini EMSG model given by the Lagrangian density $\mathcal{L}=R+βR^2+ηT_{μν}T^{μν}$ are introduced. We show that only the case $η>0$ can lead to viable cosmic bounce.

The background from non-prompt sources is determined using a statistical method based on differences in the electromagnetic showers. The cross section is measured as a function of the diphoton mass, the transverse momentum of the diphoton system, and the azimuthal angle between the two photons and is found to be consistent with perturbative QCD predictions.

title: The Interplay of Language and Law — Exploring Power Dynamics Within the Legal Systems in Nigeria
Creators: name: Aluya, Isaiah

Publisher: name: International Journal of Language & Law (JLL)
Year: 2024

description: Previous studies have examined the nexus between language and law in order to address var-ious issues unique to the Nigerian legal systems. However, little attention has been accorded to  how  this  relationship  within  the  legal  system  reflects  linguistic  dominance,  lack  of  language access, power imbalances, and inequality, all of which have an impact on the pursuit of justice by marginalised groups in a multilingual and multiethnic society like Nigeria. Con-sequently, this article investigates the nexus between language and law as well as the power dynamics present in the Nigerian legal system. The study attempts to elucidate the discursive tactics and underlying power dynamics in Nigeria’s legal system that affect legal representation, court proceedings, and access to justice. The discussion points to solutions for resolving the  problems  of  linguistic  supremacy,  limited  language  access,  power  disparities,  and  inequality. The article makes several recommendations, including offering language access services  and  interpretation  to  improve  comprehension  of  documents  and  court  proceedings; providing culturally aware legal education and training to practitioners; encouraging the use of plain language in court documents and proceedings; guaranteeing reasonably priced legal services; and addressing systemic biases and barriers by encouraging diversity and representation  among  legal  professionals.  The  study  is  exigent  because  it  provides  facts  that  could lead to policy changes that would balance power disparities in the legal system, revitalise indigenous languages, and promote a more inclusive and equitable legal system in Nigeria.

Subjects: subject: Algebraic Geometry (math.AG)

description: In this paper we continue our study of the Frobenius instability locus in the coarse moduli space of semi-stable vector bundles of rank $r$ and degree $0$ over a smooth projective curve defined over an algebraically closed field of characteristic $p>0$. In a previous paper we identified the "maximal" Frobenius instability strata with opers (more precisely as opers of type $1$ in the terminology of the present paper) and related them to certain Quot-schemes of Frobenius direct images of line bundles. The main aim of this paper is to describe for any integer $q \geq 1$ a conjectural generalization of this correspondence between opers of type $q$ (which we introduce here) and Quot-schemes of Frobenius direct images of vector bundles of rank $q$. We also give a conjectural formula for the dimension of the Frobenius instability locus.

description: Given a parabolic geometry on a smooth manifold $M$, we study a natural affine bundle $A \to M$, whose smooth sections can be identified with Weyl structures for the geometry. We show that the initial parabolic geometry defines a reductive Cartan geometry on $A$, which induces an almost bi-Lagrangian structure on $A$ and a compatible linear connection on $TA$. We prove that the split-signature metric given by the almost bi-Lagrangian structure is Einstein with non-zero scalar curvature, provided the parabolic geometry is torsion-free and $|1|$-graded. We proceed to study Weyl structures via the submanifold geometry of the image of the corresponding section in $A$. For Weyl structures satisfying appropriate non-degeneracy conditions, we derive a universal formula for the second fundamental form of this image. We also show that for locally flat projective structures, this has close relations to solutions of a projectively invariant Monge-Ampere equation and thus to properly convex projective structures.

title: Applying Large Language Models in Legal Translation: The State-of-the-Art

description: While there is no denying that new AI technologies and tools are making a significant impact on  translation,  specialized  translation  remains  problematic  for  automation  especially  in  regard  to  terminology.  Precise  and  consistent  terminology  use  requires  particular  attention  in the  field  of  legal  translation  as  a  sensitive  area  affecting  the  whole  of  the  society.  Most  recently, tools based on large language models have been gaining attention as potential game changers in the area of legal translation. How do such tools cope with the complexity of legal terminology and legal texts? Can they be trusted to perform the task of legal translation? To investigate this, a two-stage research methodology is applied: first, an analysis of papers published on the topic of large language models and legal translation by relying on quantitative bibliographic and bibliometric indicators, and second, a qualitative content analysis of the retrieved papers. The results show that despite the unparalleled interest into the application of generative AI in all spheres of life, to date there has been scarce research on its application in the  field  of  legal  translation.  The  results  of  this  study  therefore  provide  detailed  insight  into the state-of-the-art research on this novel topic, tracing the current and proposing future re-search trajectories. With a view of examining the potential of using LLMs in legal translation, it is instrumental to conduct further empirical studies from interdisciplinary perspectives including diverse legal texts and both low and high-resourced languages.

description: The decay of massive scalar field in the Schwarzschild black hole background is investigated here by consideration its quasinormal spectrum. It has been proved that the so-called $quasi-resonant$ modes, which are arbitrary long living (purely real) modes, can exist only if the effective potential is not zero at least at one of the boundaries of the $R$-region. We have observed that the quasinormal spectrum exists for all field masses and proved both analytically and numerically that when $n \to \infty$ the real part of the frequencies approaches the same asymptotical value ($\ln3/(8πM)$) as in the case of the massless field.

description: Sources of quantum light, in particular correlated photon pairs that are indistinguishable in all degrees of freedom, are the fundamental resource that enables continuous-variable quantum computation and paradigms such as Gaussian boson sampling. Nanophotonic systems offer a scalable platform for implementing sources of indistinguishable correlated photon pairs. However, such sources have so far relied on the use of a single component, such as a single waveguide or a ring resonator, which offers limited ability to tune the spectral and temporal correlations between photons. Here, we demonstrate the use of a topological photonic system comprising a two-dimensional array of ring resonators to generate indistinguishable photon pairs with dynamically tunable spectral and temporal correlations. Specifically, we realize dual-pump spontaneous four-wave mixing in this array of silicon ring resonators that exhibits topological edge states. We show that the linear dispersion of the edge states over a broad bandwidth allows us to tune the correlations, and therefore, quantum interference between photons by simply tuning the two pump frequencies in the edge band. Furthermore, we demonstrate energy-time entanglement between generated photons. We also show that our topological source is inherently protected against fabrication disorders. Our results pave the way for scalable and tunable sources of squeezed light that are indispensable for quantum information processing using continuous variables.

description: The current COVID-19 pandemic is affecting different countries in different ways. The assortment of reporting techniques alongside other issues, such as underreporting and budgetary constraints, makes predicting the spread and lethality of the virus a challenging task. This work attempts to gain a better understanding of how COVID-19 will affect one of the least studied countries, namely Brazil. Currently, several Brazilian states are in a state of lock-down. However, there is political pressure for this type of measures to be lifted. This work considers the impact that such a termination would have on how the virus evolves locally. This was done by extending the SEIR model with an on / off strategy. Given the simplicity of SEIR we also attempted to gain more insight by developing a neural regressor. We chose to employ features that current clinical studies have pinpointed has having a connection to the lethality of COVID-19. We discuss how this data can be processed in order to obtain a robust assessment.

description: The huge amount of data acquired by high-throughput sequencing requires data reduction for effective analysis. Here we give a clustering algorithm for genome-wide open chromatin data using a new data reduction method. This method regards the genome as a string of $1$s and $0$s based on a set of peaks and calculates the Hamming distances between the strings. This algorithm with the systematically optimized set of peaks enables us to quantitatively evaluate differences between samples of hematopoietic cells and classify cell types, potentially leading to a better understanding of leukemia pathogenesis.

description: Regions that currently are or have been subject to a strong process of star formation are good candidates to be intense gamma-ray and neutrino emitters. They may even perhaps be sites where ultra high energy cosmic rays are produced. Outside the Galaxy, the more powerful sites of star formation are found within very active galaxies such as starbursts (SGs) and Luminous or Ultra-Luminous Infrared Galaxies (LIRGs or ULIRGs). Some general characteristic of these objects are herein reviewed from the point of view of their possible status as high energy emitters. Revised estimations of the high energy gamma-ray yield of Arp 220 are presented.
