description: Metamaterials are artificial composite materials that, by virtue of their microstructure, exhibit properties not exhibited by their component materials. Much excitement has been generated by negatively refracting metamaterials, typically consisting of coupled, metallic, subwavelength elements that simulate electric and magnetic dipoles, because of their unusual ability to manipulate visible light, infrared waves and microwaves. In such a metamaterial, an electromagnetic wave propagates so that the direction of its energy flow is opposed to its phase velocity, a condition captured by the real part of the refractive index being negative. Here we show that a thin film comprising parallel tilted nanorods deposited by directing silver vapor obliquely towards a large-area substrate displays a negative real refractive index in the visible regime. Since vapor deposition is a very well-established technique to deposit thin films in the photonics industry, our result is promising for large-scale production of negatively refracting metamaterials

Higher education

description: Mintzberg’s version of emergent strategy is based on the idea that strategies are contingent on circumstances that change from time to time often very rapidly and therefore papers focused on strategy and detailed planning are limited in their practical application. The word strategy as far as Mintzberg is concerned is anathema, therefore, introducing a concept that has a misconception embedded in it. This paper claims that education for sustainable development and higher education institutions’ survival depends on adopting postmodern thinking, in other words, digital transformation.

description: The energy and angular dependence of double differential cross sections dsigma/dOmega dE were measured for p, d, t, 3,4He, 6,7Li, 7,9Be, and 10,11B produced in collisions of 0.175 GeV protons with Ni target. The analysis of measured dfferential cross sections allowed to extract total production cross sections for ejectiles listed above. The shape of the spectra and angular distributions indicate the presence of other nonequilibrium processes besides the emission of nucleons from the intranuclear cascade, and besides the evaporation of various particles from remnants of intranuclear cascade. These nonequilibrium processes consist of coalescence of nucleons into light charged particles during the intranuclear cascade, of the fireball emission which contributes to the cross sections of protons and deuterons, and of the break-up of the target nucleus which leads to the emission of intermediate mass fragments. All such processes were found earlier at beam energies 1.2, 1.9, and 2.5 GeV for Ni as well as for Au targets, however, significant differences in properties of these processes at high and low beam energy are observed in the present study.

description: Landau's Fermi-liquid (FL) theory has been successful at the phenomenological description of the normal phase of many different Fermi systems. Using a dilute atomic Fermi fluid with tunable interactions, we investigate the microscopic basis of Landau's theory with a system describable from first principles. We study transport properties of an interacting Fermi gas by measuring its density response to a periodic external perturbation. In an ideal Fermi gas, we measure for the first time the celebrated Lindhard function. As the system is brought from the collisionless to the hydrodynamic regime, we observe the emergence of sound, and find that the experimental observations are quantitatively understood with a first-principle transport equation for the FL. When the system is more strongly interacting, we find deviations from such predictions. Finally, we observe the shape of the quasiparticle excitations directly from momentum-space tomography and see how it evolves from the collisionless to the collisional regime. Our study establishes this system as a clean platform for studying Landau's theory of the FL and paves the way for extending the theory to more exotic conditions, such as nonlinear dynamics and FLs with strong correlations in versatile settings.

description: We present a flexible interactive 3D morpho-kinematical modeling application for astrophysics. Compared to other systems, our application reduces the restrictions on the physical assumptions, data type and amount that is required for a reconstruction of an object's morphology. It is one of the first publicly available tools to apply interactive graphics to astrophysical modeling. The tool allows astrophysicists to provide a-priori knowledge about the object by interactively defining 3D structural elements. By direct comparison of model prediction with observational data, model parameters can then be automatically optimized to fit the observation. The tool has already been successfully used in a number of astrophysical research projects.

description: Credit ratings are used to reduce the information gap between investors and borrowers (Duff and Einig, 2009) and have been a significant area of interest to investors, regulators, and other market participants over the last two decades. Numerous studies have shown that assigned ratings and rating changes have a significant impact on the pricing of risk and the rate of return for fixed income instruments (Livingston et al, 2008). There are seven major international credit rating agencies (CRAs) within the industry, the main two accounting for 80% of the market are Moody’s Investors Service, Standard and Poor’s (S&P) and Fitch accounting for around 15% of the market.

It can be viewed as the elliptic deformation of Wakimoto realization. Two screening currents are constructed; they commute or anti-commute with $U_{q,p}(\widehat{sl_2})$ modulo total q-differences. The free fields realization for two types vertex operators nominated as the type $I$ and the type $II$ vertex operators are presented. The twisted version of the two types vertex operators are also obtained. They all play crucial roles in calculating correlation functions.

description: The hallmark of topological crystalline insulators is the emergence of a robust electronic state in a bandgap localized at the boundary of the material. However, end, edge, and surface states can also have a nontopological origin. Unfortunately, topological invariants such as the winding number and Zak phase are often not directly experimentally accessible for solids. In addition to topological invariants, the position of the Wannier centers provides a fingerprint for the topological character of a material. Here, we demonstrate a method to experimentally determine the location of Wannier centers in artificial lattices made of Cs/InAs(111)A by integrating the density of states. We determine the locations of the Wannier centers for various 1D chains, topological and trivial, and corroborate our findings with tight-binding simulations.

description: We investigate the geometrical structure of multiply enhanced codimension-two singularities in the $SU(5)$ model of six-dimensional F-theory, where the rank of the singularity increases by two or more. We perform blow-up processes for the enhancement $SU(5)\rightarrow G'$, where $G'=E_6$, $E_7$ or $E_8$, to examine whether a sufficient set of exceptional curves emerge that can explain the charged matter generation predicted from anomaly cancelation. We first apply one of the six Esole-Yau small resolutions to the multiply enhanced singularities, but it turns out that the proper transform of the threefold equation does not reflect changes in the singularity or how the generic codimension-two singularities gather there. We then use a(n) (apparently) different way of small resolutions than Esole-Yau to find that, except for the cases of $G'= E_6$ and special cases of $E_7$, either (1) the resolution only yields exceptional curves that are insufficient to cancel the anomaly, or (2) there arises a type of singularity that is neither a conifold nor a generalized conifold singularity. Finally, we revisit the Esole-Yau small resolution and show that the change of the way of small resolutions amounts to simply exchanging the proper transform and the constraint condition, and under this exchange the two ways of small resolutions are completely equivalent.

Finance-gender gap: Perceptions of access to finance for female entrepreneurs in Wales
Creators: name: Mabwe, Kumbirai

Publisher: name: Cardiff Metropolitan University
Year: 2023
Subjects: Gender, policy and administration

description: Issues on gender, entrepreneurship, and access to finance have been identified as problematic in literature. Previous research on access to finance supports the existence of a gender gap within the small and medium enterprise (SME) sector, with access to finance more difficult, particularly for female-owned SMEs. Literature highlights that the gap and disadvantages that women face do not arise as a result of women’s lack of ability. Instead, they arise due to complex and multidimensional constraints occurring as a result of the gender stereotypes of entrepreneurship(women are perceived as less capable entrepreneurs than men). This study draws from the social feminist theory and liberal feminist theory and uses semi-structured interviews to give a‘voice’ to women in the investigation of women’s perceptions of their experience of seeking and successfully obtaining business finance for the creation, growth, and development of their small business in Wales.

We use here the GALEX (Galaxy Evolution Explorer) Near-UV and Far-UV measurements (complemented with optical data from Sloan Digital Sky Survey (SDSS) and XMM-Newton X-ray spectra) of a sample of 83 X-ray selected type 1 AGN extracted from the XMM-Newton Bright Serendipitous Survey to study their spectral energy distribution (SED) in the optical, Near and Far-UV and X-ray energy bands. We have constrained the luminosity of the accretion disk emission component and calculated the hard X-ray bolometric corrections for a significant sample of AGN spanning a large range in properties (z, L(x)).

Measurement of stress fracturing and bulking for deformation-based ground support design calibration in a deep caving operation
Creators: name: Primadiansyah, Avesiena Adrian
Publisher: name: University of British Columbia
Year: 2024

description: The demand for critical minerals continues to increase as the world shifts towards green energy solutions. This trend has compelled the mining industry to mine deeper as near-surface mineral deposits become depleted, exposing projects to higher-stress environments in more massive, brittle rock. Under high stresses, massive rock fails via stress fracturing, resulting in rock spalls that can detach from the excavation perimeter in a progressive, non-violent manner as spalling or suddenly and violently as strainbursting. These phenomena ultimately lead to bulking around the excavation that increases susceptibility to damage or failure of safety-critical rock support systems, creating risks for workers and costly interruptions in production. Deformation-based support design (DBSD) is a recent and innovative approach for designing support in highly stressed brittle rock, offering several advantages to address these challenges. However, the limited availability of purpose-focused field-based data and systematic procedures for effectively determining DBSD critical parameters often hinders its optimization, particularly in deep caving operations. This research provides a systematic procedure and recommendations to improve the justification and optimization of the DBSD approach using data from the PT Freeport Indonesia (PTFI) Deep Mill Level Zone (DMLZ) panel cave mine. The study introduces a systematic process that integrates stress fracturing and bulking monitoring techniques, leveraging field data to calibrate the critical parameters of the DBSD. A site-specific predictive function is proposed for estimating the depth of stress fracturing and the corresponding displacement based on the transient nature of the bulking factor across the extraction level footprint. Implementing this procedure into PTFI's DBSD tool effectively improves the design approach and forecasting of preventative support maintenance requirements, thereby promoting the integrity and reliability of the excavation.

description: Point-contact Andreev-reflection measurements were performed in SmFeAsO_{0.8}F_{0.2} polycrystals with T_c \simeq 53 K. The experimental conductance curves reproducibly exhibit peaks around \pm 6 mV and shoulders at V \sim 16-20 mV, indicating the presence of two nodeless superconducting gaps. While the single-band Blonder-Tinkham-Klapwijk fit can only reproduce a small central portion of the conductance curve, the two-gap one accounts remarkably well for the shape of the whole experimental dI/dV. The fits of the normalized curves give Delta_1(0) = 6.15 \pm 0.45 meV and Delta_2(0) = 18 \pm 3 meV. Both gaps close at the same temperature and follow a BCS-like behavior.

description: We study the statistics of the fluctuating electron temperature in a metallic island coupled to reservoirs via resistive contacts and driven out of equilibrium by either a temperature or voltage difference between the reservoirs. The fluctuations of temperature are well-defined provided that the energy relaxation rate inside the island exceeds the rate of energy exchange with the reservoirs. We quantify these fluctuations in the regime beyond the Gaussian approximation and elucidate their dependence on the nature of the electronic contacts.

description: We study scalar-tensor gravitational theories using on-shell amplitude methods. We focus on theories with gravity coupled to a massless scalar via the Gauss-Bonnet and Chern-Simons terms. In this framework, we calculate the waveforms for classical scalar radiation emitted in scattering of macroscopic objects, including spin effects. To this end, we use the Kosower-Maybee-O'Connell formalism, with the 5-particle amplitude for scalar emission in matter scattering calculated at tree level using the unitarity-factorization bootstrap techniques. We also discuss in detail the dependence of that amplitude on the contact terms of the intermediate 4-particle scalar-graviton-matter amplitude. Finally, we discuss the conditions for resolvability of classical scalar radiation.

Deep learning-based biomedical images classification and segmentation from limited data
Creators: name: Jana, Ananya
Publisher: name: No Publisher Supplied
Year: 2023

description: Deep Learning based methods have become immensely popular in recent years. While these methods look very promising, they are not always translated to the medical images domain as-is due to the nature of biomedical images being different from the natural images. The problems arising in the medical images domain are considerably different. In addition, another problem is that the amount of medical images available publicly is rather limited and hence the challenge lies in enabling methods to learn from limited medical data. In this dissertation we worked on different computer vision tasks such as image classification and image segmentation and on a diverse set of medical data such as Computed Tomography (CT) images, Histopathology Whole Slide Image (WSI) and intraoral scans with the recurrent underlying theme as learning from limited data. We begin with proposing novel deep learning based solutions for liver fibrosis and NAS scores classification. Liver fibrosis is a disease that brings in very subtle changes in the liver texture in the different stages of the disease. Hence we design a network suitable for discriminating between subtle changes in texture by focusing on the individual pixel and its neighborhood. We then proceed on to develop a framework aimed at early prognosis of subjects at risk of developing liver cancer. Next, we shift our focus to the problem of tooth segmentation from 3D intraoral scans. We propose a novel deep learning based framework for tooth segmentation from intraoral scans and with a simplified tooth mesh cell representation as the input data. In this dissertation, we also make an interesting observation regarding the data under discussion and explore a relevant question that came up naturally - how much representation can be learnt from a single intraoral scan.Overall, our solutions, approaches and findings together provide new insights into the possibilities and liabilities associated with learning from limited data. We believe which these findings can help develop robust solutions for critical medical applications.
Validity of Laser Doppler Flowmetry in Predicting Outcome in Murine Intraluminal Middle Cerebral Artery Occlusion Stroke
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background—Laser Doppler flowmetry (LDF) can reliably reflect brain perfusion in experimental stroke by monitoring both the degree and the duration of relative regional cerebral blood flow (rCBF). Variation in rCBF was continuously monitored in 68 mice undergoing middle cerebral artery occlusion (MCAO) and 25 mice undergoing sham-operation and documented as LDF (%). Transcranial LDF changes in the territory of right middle cerebral artery during MCAO procedure were correlated with corrected infarct volume (CIV) and neurological deficit score (NDS). Methods—Ninety-three C57BL/6 mice (Harlan Laboratories, Indianapolis, IN) between 9 and 11 weeks old were randomly selected and assigned to either MCAO for 45 minutes (n = 68) or sham group (n = 25). Ischemia was induced using the transient intraluminal filament model of MCAO based on Koizumi's method and transcranial LDF was used to measure CBF during the procedure. Neurological deficits were measured at 2 and 23 hours after MCA reperfusion with NDS and 2% triphenyltetrazolium chloride (TTC) staining of carefully dissected brains was performed at 23 hours after reperfusion to determine infarct area. Results—After common carotid artery occlusion (CCAO), there was a negative association between LDF drop from base line and NDS at 2 hours (r = −0.43, P = 0.038) and 23 hours (r = −0.61, P = 0.003). Also, a negative correlation was noted between MCA reperfusion LDF and NDS at 23 hours (r = −0.53, P = 0.001). Moreover, post-MCA reperfusion LDF had a positive association with initial CCAO LDF (r = 0.761, P = 0.000) and MCA occlusion LDF (r = 0.31, P = 0.036) in predicting neurological outcome. NDS at 23 hours corresponded well with the infarct volume (r = 0.31, P = 0.005). Conclusions—Greater augmentation of rCBF after MCA reperfusion was associated with improved neurological deficit scoring. Interestingly, greater reduction of regional cerebral blood flow after CCAO was also associated with improved neurological outcomes. The favorable neurological outcome is possibly due to interplay of factors such as vascular reserve, collaterals, and autoregulation mechanisms. We propose LDF changes as an additional noninvasive prognosticator of stroke outcome in the setting of experimental brain ischemia.

description: Low-mass stars are element factories that efficiently release their products in the final stages of their evolution by means of stellar winds. Since they are large in number, they contribute significantly to the cosmic matter cycle. To assess this contribution quantitatively, it is crucial to obtain a detailed picture of the stellar interior, particularly with regard to nucleosynthesis and mixing mechanisms. We seek to benchmark stellar evolutionary models of low-mass stars. In particular, we measure the surface abundance of ^{12}C in thermally pulsing AGB stars with well-known mass and metallicity, which can be used to infer information about the onset and efficiency of the third dredge-up. We recorded high-resolution near-infrared spectra of AGB stars in the LMC cluster NGC 1978. The sample comprised both oxygen-rich and carbon-rich stars, and is well-constrained in terms of the stellar mass, metallicity, and age. We derived the C/O and ^{12}C/^{13}C ratio from the target spectra by a comparison to synthetic spectra. Then, we compared the outcomes of stellar evolutionary models with our measurements. The M stars in NGC 1978 show values of C/O and ^{12}C/^{13}C that can best be explained with moderate extra-mixing on the RGB coupled to a moderate oxygen enhancement in the chemical composition. These oxygen-rich stars do not seem to have undergone third dredge-up episodes (yet). The C stars show carbon-to-oxygen and carbon isotopic ratios consistent with the occurrence of the third dredge-up. We did not find S stars in this cluster. None of the theoretical schemes that we considered was able to reproduce the observations appropriately. Instead, we discuss some non-standard scenarios to explain the puzzling abundance pattern in NGC 1978.

description: At long distances interactions between neutral ground state atoms can be described by the Van der Waals potential V(r) =-C6/r^6-C8/r^8 - ... . In the ultra-cold regime atom-atom scattering is dominated by s-waves phase shifts given by an effective range expansion p cot d0 (p) = -1/a0 + r0 p^2/2 + ... in terms of the scattering length a0 and the effective range r0. We show that while for these potentials the scattering length cannot be predicted, the effective range is given by the universal low energy theorem r0 = A + B/a0+ C/a0^2 where A,B and C depend on the dispersion coefficients Cn and the reduced di-atom mass. We confront this formula to about a hundred determinations of r0 and a0 and show why the result is dominated by the leading dispersion coefficient C6. Universality and scaling extends much beyond naive dimensional analysis estimates.

description: Research work in the area of the Global Electric Circuit (GEC) has rapidly expanded in recent years mainly through observations of lightning from satellites and ground-based networks and observations of optical emissions between cloud and the ionosphere. After reviewing this progress, we critically examine the role of various generators of the currents flowing in the lower and upper atmosphere and supplying currents to the GEC. The role of aerosols and cosmic rays in controlling the GEC and linkage between climate, solarterrestrial relationships and the GEC has been briefly discussed. Some unsolved problems in this area are reported for future investigations.

description: The development of fast and efficient quantum batteries is crucial for the prospects of quantum technologies. We show that both requirements are accomplished in the paradigmatic model of a harmonic oscillator strongly coupled to a highly non-Markovian thermal reservoir. At short times, a dynamical blockade of the reservoir prevents the leakage of energy towards its degrees of freedom, promoting a significant accumulation of energy in the battery with high efficiency. The possibility of implementing these conditions in $LC$ quantum circuits opens up new avenues for solid-state quantum batteries.

Theoretical prediction of multiferroicity in double perovskite Y$_2$NiMnO$_6$

description: We put forward double perovskites of the R$_2$NiMnO$_6$ family (with $R$ a rare-earth atom) as a new class of multiferroics on the basis of {\it ab initio} density functional calculations. We show that changing $R$ from La to Y drives the ground-state from ferromagnetic to antiferromagnetic with $\uparrow\uparrow\downarrow\downarrow$ spin patterns. This E$^*$-type ordering breaks inversion symmetry and generates a ferroelectric polarization of few $μC/cm^2$. By analyzing a model Hamiltonian we understand the microscopic origin of this transition and show that an external electric field can be used to tune the transition, thus allowing electrical control of the magnetization.
