Non-Additive Optical Response in Transition Metal Dichalcogenides Heterostructures

Van der Waals (vdW) heterostructures pave the way to achieve the desired material properties for a variety of applications. In this way, new scientific and industrial challenges and fundamental questions arise. One of them is whether vdW materials preserve their original optical response when assembled in a heterostructure. Here, we resolve this issue for four exemplary monolayer heterostructures: MoS2/Gr, MoS2/hBN, WS2/Gr, and WS2/hBN. Through joint Raman, ellipsometry, and reflectance spectroscopies, we discovered that heterostructures alter MoS2 and WS2 optical constants. Furthermore, despite the similarity of MoS2 and WS2 monolayers, their behavior in heterostructures is markedly different. While MoS2 has large changes, particularly above 3 eV, WS2 experiences modest changes in optical constants. We also detected a transformation from dark into bright exciton for MoS2/Gr heterostructure. In summary, our findings provide clear evidence that the optical response of heterostructures is not the sum of optical properties of its constituents.
CONSTANTS FOR EMPIRICAL EXPRESSIONS FOR DOWNCOMING ATMOSPHERIC RADIATION UNDER CLOUDLESS SKY

Abstract Magnitudes of the constants in Brunt's empirical expression for nocturnal radiation were determined from continuous automatic recordings of atmospheric radiation in California under cloudless skies and interpreted for the humidity at 1400 hours on the previous day. With these constants, useful estimates of the average nighttime atmospheric radiation rate can be computed from the local 1400-hours vapor pressure and average nocturnal air temperature as reported by all first-order U. S. Weather Bureau stations. With careful interpretation of weather records, the probable error will be about 3 per cent. Comparisons are made with Loennquist's formula and with calculations by atmospheric radiation charts from known soundings for extreme conditions leading to radiation frosts in southern California. Limited observations of daytime atmospheric radiation indicate that there is little difference in the average value of the radiation ratio between night and day when the character of the overhead air mass is.
A General Projection Method for a System of Relaxed Cocoercive Variational Inequalities in Hilbert Spaces

We consider a new algorithm for a generalized system for relaxed cocoercive nonlinear inequalities involving three different operators in Hilbert spaces by the convergence of projection methods. Our results include the previous results as special cases extend and improve the main results of R. U. Verma (2004), S. S. Chang et al. (2007), Z. Y. Huang and M. A. Noor (2007), and many others.
Elastic wave modelling by an integrated finite difference method

SUMMARY We have developed a finite difference method for modelling the elastic wave equation in the time domain, based on integrating the elastic parameters. In this method, we adopt the strategy of integrating the elastic parameters over a limited space; so, it is suitable for wave propagation modelling in fractured media, for which we use an equivalent media with the elastic coefficients averaged over a fractured space. This elastic parameters integration allows us to reduce the five simultaneous equations usually used to describe the velocity and stress propagation to just two, in terms of velocity alone, providing a significant saving in computational memory. In this paper, we discuss the derivation and computational implementation of the method for 2-D media, including the seismic source and both reflecting and absorbing boundary conditions, and illustrate it with some synthetic models of heterogeneous, anisotropic and fractured media.
Implementation of Sustainable Banking: Study in Indonesia and Singapore

: Currently, ASEAN Banks have sought sustainable banking disclosures by referring to the regulations in their respective countries and the frameworks of various assessment organizations. However, due to the many frameworks, the issue of looming or too many frameworks have to be adopted. This research aims to develop a banking framework by combining various frameworks, namely SUSBA, SASB, GRI G4 FSSS, and UNEP FI, added to the pillars of stakeholder engagement and digital transformation to be a more comprehensive sustainable banking framework. This study uses qualitative methods by conducting interviews and content analysis. Content analysis is carried out by scoring the sustainability reports and/or annual reports 2020 of 26 banks in Indonesia and three banks in Singapore. This study reveals that the pillars of stakeholder engagement and digital transformation need to be disclosed in sustainable banking because they must continue to maintain good relations with stakeholders and use artificial intelligence in bank operations. The unique contribution of this study is the comprehensive sustainable banking framework that mentioned specifically about stakeholder engagement and digital transformation.
Are GANs overkill for NLP?

This work offers a novel theoretical perspective on why, despite numerous attempts, adversarial approaches to generative modeling (e.g., GANs) have not been as successful for certain generation tasks, particularly sequential tasks such as Natural Language Generation, as they have in others, such as Computer Vision. In particular, on sequential data such as text, maximum-likelihood approaches are signiﬁcantly more utilized than GANs. We show that, while it may seem that maximizing likelihood is inherently different than minimizing distinguishability, this distinction is largely an artifact of the limited representational capacity of the model family, for a wide class of adversarial objectives. We give a theoretical model in which minimizing KL-divergence (i.e., maximizing likelihood) is a more efﬁcient approach to effectively minimizing the same distinguishability criteria that adversarial models seek to optimize. Reductions show that minimizing distinguishability can be seen as simply boosting likelihood for certain families of models including n-gram models and neural networks with a softmax output layer. To achieve a full polynomial-time reduction, a novel next-token distinguishability model is considered. Some preliminary empirical evidence is also provided to substantiate our theoretical analyses.
Fresh and Hardened Properties of Lightweight Self Compacting Concrete Containing Attapulgite

The main objectives of this study were investigating the possibility of producing lightweight self - Compacting concrete (LWSCC) by using artificial coarse lightweight aggregate manufactured by burning locally available Attapulgite clay, estimating the optimum dosage of high reactivity Attapulgite (HRA) and studying its effects on fresh and hardened properties of LWSCC when using it as a partial replacement by weight of cement. Tests results showed that, It is possible to produce (LWSCC) by using Attapulgite as artificial coarse (LWA) and (HRA). The optimum content for (HRA) used in this study was 10 %, the percentages of increment in compressive strength and splitting tensile strength with 10% (HRA) relative to reference mix were (10.0%, 12.1%, 11.1% and 12.4%) and ( 12.0%, 18.2%, 16.6% and 16.2%) for 7, 28, 56 and 90 days respectively. The values of the calculated equilibrium density ranged between (1788 and 1829) kg/m 3
A HYBRID DILATION APPROACH FOR REMOTE SENSING SCENE IMAGE CLASSIFICATION

While fine-tuning a transfer learning model alleviates the need for a vast amount of training data, it still comes with a few challenges. One of them is the range of image dimensions that the input layer of a model accepts. This issue is of interest, especially in tasks that require the use of a transfer learning model. In scene classification, for instance, images could come in varying sizes that could be too large/small to be fed into the first layer of the architecture. While resizing could be used to trim images to a required shape, that is usually not possible for images with tiny dimensions, for example, in the case of the EuroSAT dataset. This paper proposes an Xception model-based framework that accepts images of arbitrary size and then resizes or interpolates them before extracting and enhancing the discriminative features using an adaptive dilation module. After applying the approach for scene classification problems and carrying out a number of experiments and simulations, we achieved 98.55% accuracy on the EuroSAT dataset, 99.22% on UCM , 96.15% on AID and 96.04% on the SIRI-WHU dataset, respectively. We also monitored the micro-average and macro-average ROC curve scores for all the datasets to further evaluate the proposed model’s effectiveness.
The Morse index theorem where the ends are submanifolds

In this paper the Morse Index Theorem is proven in the case where submanifolds P and Q are at the endpoints of a geodesic, -Y. At -Y, the index of the Hessian of the energy function defined on paths joining P and Q is computed using P-focal points, and a calculation at the endpoint of -Y, involving the second fundamental form of Q.
Spectral Characteristics of the Pseudosonic Component of Hydrodynamical Noise In a Longitudinal Flow Around a Flexible Cylinder

Wall pressure fluctuations were measured in an axisymmetric turbulent boundary layer on a flexible cylinder parallel to the flow at Reynolds numbers of 10 7 ‐10 8 and boundary layer thickness to cylinder radius ratio of 2:9 ‐3:2. It has been found out that the intensity of pressure fluctuations in the turbulent boundary layer on the flexible cylinder is higher than that on a rigid cylinder or on a flat plate. An adjusted power spectrum of the pressure fluctuations is presented. The acousto-hydrodynamic factor for the spot sensor of the pressure fluctuations has been determined. The power spectrum of the wall pressure fluctuations on the flexible cylinder has been found out to be higher than that on the rigid cylinder. With the increase of velocity of the flow around the flexible cylinder there occurs a redistribution of energy of the turbulent pressure fluctuations from the high frequency area of the power spectrum into lower frequencies. In the frequency band ! + ’ (0:2 ‐0:3) the maximums of the power spectrum and the coherence function irrespective of separation between the pressure fluctuation sensors are observed. With the increase of the frequency and separation, the coherence function descends, which characterizes a degeneracy of vortical structures both in scale and in the length of the cylinder in the flow.
Convergence rates and powers of six power-divergence statistics for testing independence in 2 by 2 contingency table

Several tests for testing independence of 2 by 2 contingency tables have been proposed over the years. Cressie and Read (1984) identified several of these tests as members of a power-divergence family, and much of the characteristics for these tests are unified. However, the question of which test is best is still not fully understood. This paper provides algorithms for chi-square estimates and investigates the convergence rates and powers of these chi-square tests.
THE HUBBLE PARAMETER

Distance determinations to individual galaxies, groups, and clusters are critically reviewed. All modern distance determinations have been reduced to a common and internally consistent system. These distances are then used to discuss the present status of the extragalactic distance scale and of the Hubble Parameter, HO. It is shown that the classical distance scale "problem" starts quite abruptly at D > 3 Mpc. It is emphasized that the reasons for this discrepancy are entirely independent of difficulties associated with large-scale deviations from a smooth Hubble flow. From eight different techniques the mean distance modulus of the Virgo cluster is found to be (m-M)o = 31.0 ± ). 15 (D = 15.8 ± 1.1 Mpc). Twelve determinations of the difference between the distance moduli of the Coma and Virgo clusters yield Delta(m-M)o = 3.71 ± 0.05 mag and hence a Coma distance modulus (m-M)o = 34.71 ± 0.16 (D = 87 ± 6 Mpc). Combining this distance with the Coma cluster's cosmological velocity of 7210 km s-1 yields a value Ho (local) = 83 ± 6 km s-1 Mpc-1. From the velocity-distance relation for the brightest galaxies in clusters of Bautz-Morgan types I and I-II it is found that Ho (global)/Holocal = 0.92 ± 0.08, in which "local" refers to northern clusters with Vo < 10,000 km s-1. In other words the cluster data do not show a statistically significant difference between the local and global values of the Hubble parameter. If one nevertheless adopts Hoglobal/Holocal = 0.92 ± 0.08 then one obtains Hoglobal = 76 ± 9 km s-1 Mpc-1. This observed value of Ho differs at the 3 sigma level from that predicted by theories of stellar evolution in conjunction with canonical models of the Universe with Theta = 1 and Lambda = 0.
Droplet spreading, imbibition and solidification on porous media

The spreading, imbibition and solidification of a hot two-dimensional droplet on a cooler porous substrate is studied. Lubrication theory and asymptotic reduction are used to derive a coupled system of evolution equations for the droplet thickness and vertical extents of the solid/melt boundary and the saturation front within the porous medium. This medium is assumed to be a membrane composed of an array of pores having fixed width. A precursor layer model and a disjoining pressure are used to relieve the singularity at the contact line. When the solidification and imbibition time scales are similar to those associated with spreading, the dynamics follow two stages: spreading and imbibition accompanied by solidification within the pores leading to their blockage, followed by contact line arrest and basal solidification of the droplet; the possibility of crust formation at the gas–melt interface is excluded from the present study. The dependence of the dynamics on the relevant system parameters is elucidated. Furthermore, our modelling predictions compare favourably with experimental data also obtained as part of the present work.
Three-dimensional Simulations of Black Hole Tori

The global hydrodynamic nonaxisymmetric instabilities in thick constant angular momentum (l) accretion gas tori in orbit around a Schwarzschild black hole are investigated via 2D and 3D numerical simulations. A radially-wide torus is found to develop and m = 1 nonaxisymmetric density perturbation near the pressure maximum and a trailing spiral wave that extends through the outer part of the torus. This global wave transports angular momentum through the torus, causing the average angular momentum distribution to evolve slowly away from l = constant. The unstable mode drives an accretion flow from the torus into the black hole. The role of accretion is investigated by modeling a wide torus with an inner boundary at the cusp of the Schwarzschild effective potential. In such a torus, accretion is present throughout the evolution; only modest unstable mode growth is observed, and saturation occurs at low amplitude. Comparison simulations performed in the torus equatorial plane show qualitative similarities between the 2D and 3D system, although the 3D modes have a function dependence on height.
CO Emission from the Dwarf Irregular Galaxy NGC 6822

Four regions of the Local Group dwarf irregular galaxy NGC 6822 have been mapped for CO emission. The regions observed were centered on bright H II regions and strong H I peaks. Of the 47 lines of sight observed, CO emission was detected at only three. The peak line strengths observed in NGC 6822 are intermediate between the line strengths observed at comparable spatial resolution in the Large and Small Magellanic Clouds. In contrast, the irregular galaxy IC 10, which has a metallicity very similar to NGC 6822, has CO line strengths that are an order of magnitude larger than those in NGC 6822
Microstructural and macroscopic properties of cold sprayed copper coatings

Cold spraying is a coating technique in which the formation of dense, tightly bonded coatings occurs only due to the kinetic energy of high velocity particles of the spray powder. These particles are still in the solid state as they impinge on the substrate. This study correlates optimized deposition parameters with the corresponding microstructure as well as mechanical and conductive behavior of cold sprayed copper coatings in order to explain possible bonding mechanisms. In addition, the performance of cold sprayed copper coatings is compared to that of cold rolled copper and to coatings prepared by thermal spray methods.
Characterization of the interface properties in a-Si : H/c-Si heterostructures by photoluminescence

Photoluminescence measurements on hydrogenated amorphous silicon/crystalline silicon (a-Si : H/c-Si) heterostructures have been used for two aspects of their characterization: the monitoring of the crystalline silicon wafers and of their interface properties after different steps of solar cell processing and the tracking of interface properties on purpose-built symmetrical structures with different amorphous silicon overlayers. The difference in the quasi-Fermi level splittings in these symmetrical structures, determined both experimentally and by numerical modelling, suggests an energetic position of the interface defect distribution with a peak at around 0.7–0.8 eV above the c-Si valence band edge. Numerical modelling is also applied to the structures after solar cell processing steps and consistently tracks the variation in quasi-Fermi level splitting, i.e. excess carrier densities, in the c-Si layer. The agreement in the experimental and simulated open-circuit voltages for the final cell adds confidence to the interface defect parameters determined.
Linear and nonlinear evolution of a localized disturbance in polymeric channel flow

Abstract The evolution of an initially localized disturbance in polymeric channel flow is investigated, with the FENE-P model used to characterize the viscoelastic behaviour of the flow. In the linear growth regime, the flow response is stabilized by viscoelasticity, and the maximum attainable disturbance-energy amplification is reduced with increasing polymer concentration. The reduction in the energy growth rate is attributed to the polymer work, which plays a dual role. First, a spanwise polymer-work term develops, and is explained by the tilting action of the wall-normal vorticity on the mean streamwise conformation tensor. This resistive term weakens the spanwise velocity perturbation thus reducing the energy of the localized disturbance. The second action of the polymer is analogous, with a wall-normal polymer work term that weakens the vertical velocity perturbation. Its indirect effect on energy growth is substantial since it reduces the production of Reynolds shear stress and in turn of the streamwise velocity perturbation, or streaks. During the early stages of nonlinear growth, the dominant effect of the polymer is to suppress the large-scale streaky structures which are strongly amplified in Newtonian flows. As a result, the process of transition to turbulence is prolonged and, after transition, a drag-reduced turbulent state is attained.
Comparisons of density profiles in JT-60U tokamak and LHD helical plasmas with low collisionality

In order to understand particle transport systematically in toroidal plasmas, electron density profiles were compared in JT-60U tokamak and LHD helical plasmas with low collisionality. The peakedness of density profiles increased with decreasing collisionality in ELMy H-mode plasmas of JT-60U when the collisionality at half the minor radius was in the collisionless regime. The collisionality dependence of density profiles in LHD plasmas was similar to that in JT-60U plasmas in the same collisionality regime when neoclassical transport was reduced by geometrical optimization. On the other hand, in LHD plasmas having relatively larger neoclassical transport than that in the above case, the peakedness of the density profiles decreased with decreasing collisionality. Density profiles in LHD plasmas tend to approach those in JT-60U, which are dominated by anomalous transport, as the contribution of neoclassical transport was reduced.
On a Statistical Theory of Solute Transport in Porous Media

Consider the motion of a solute molecule in a homogeneous isotropic porous medium saturated with a pure liquid. The following assumptions are made on the velocity of the molecule: the time intervals between successive collisions of the molecule with the solid matter of the medium are i.i. d. random variables; the molecule is scattered by these collisions in random directions which are i.i. d. uniform and independent of the collision times; in between two successive collisions with the solid phase the velocity of the molecule is governed by the Langevin equation. Under these and mild additional assumptions it is proved that the position $\{ X(t):t\geqq 0\} $ of the molecule is approximately a Brownian motion. If the solute molecules are weakly interacting among themselves, then the above result leads to a macroscopic parabolic equation (1.14) governing solute concentration. If the successive collision times with the solid phase are assumed to be exponential, then the velocity $\{ v(t):t\geqq 0\} $ as well as.
Research on foreign object damage and grinding repair schemes of compressor blades

Foreign object damage (FOD) on compressor blades of aero-engines lowers the capacity of blades and poses a serious threat to civil aviation safety, so the repair of blades with FOD deserves more attention. The finite element model of the aero-engine compressor blade was established, and the finite element analysis was carried out on the damaged blades with FOD notches and the blades after grinding and repair. The natural frequencies of different types of blades and the global and local peak stress under rotating conditions were compared. It was confirmed that the stiffness of the repaired blades was acceptable, and the optimal grinding repair scheme was selected.
