description: The structure and stability of dilute degenerate Fermi gases trapped in an external potential is discussed with special emphasis on the influence of s- and p-wave interactions. In a first step an Effective Contact Interaction for all partial waves is derived, which reproduces the energy spectrum of the full potential within a mean-field model space. Using the s- and p-wave part the energy density of the multi-component Fermi gas is calculated in Thomas-Fermi approximation. On this basis the stability of the one- and two-component Fermi gas against mean-field induced collapse is investigated. Explicit stability conditions in terms of density and total particle number are given. For the single-component system attractive p-wave interactions limit the density of the gas. In the two-component case a subtle competition of s- and p-wave interactions occurs and gives rise to a rich variety of phenomena. A repulsive p-wave part, for example, can stabilize a two-component system that would otherwise collapse due to an attractive s-wave interaction. It is concluded that the p-wave interaction may have important influence on the structure of degenerate Fermi gases and should not be discarded from the outset.

description: We present an original concept for patch generation: we propose to do it directly in production. Our idea is to generate patches on-the-fly based on automated analysis of the failure context. By doing this in production, the repair process has complete access to the system state at the point of failure. We propose to perform live regression testing of the generated patches directly on the production traffic, by feeding a sandboxed version of the application with a copy of the production traffic, the 'shadow traffic'. Our concept widens the applicability of program repair, because it removes the requirements of having a failing test case.

On the Particle Definition in the presence of Black Holes

Year: 2000
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A canonical particle definition via the diagonalisation of the Hamiltonian for a quantum field theory in specific curved space-times is presented. Within the provided approach radial ingoing or outgoing Minkowski particles do not exist. An application of this formalism to the Rindler metric recovers the well-known Unruh effect. For the situation of a black hole the Hamiltonian splits up into two independent parts accounting for the interior and the exterior domain, respectively. It turns out that a reasonable particle definition may be accomplished for the outside region only. The Hamiltonian of the field inside the black hole is unbounded from above and below and hence possesses no ground state. The corresponding equation of motion displays a linear global instability. Possible consequences of this instability are discussed and its relations to the sonic analogues of black holes are addressed. PACS-numbers: 04.70.Dy, 04.62.+v, 10.10.Ef, 03.65.Db.

description: We have measured the electrodynamic response in the metallic state of three highly anisotropic conductors, (TMTSF)_2 X, where X=PF_6, AsF_6, or ClO_4, and TMTSF is the organic molecule tetramethyltetraselenofulvalene. In all three cases we find dramatic deviations from a simple Drude response. The optical conductivity has two features: a narrow mode at zero frequency, with a small spectral weight, and a mode centered around 200 cm^{-1}, with nearly all of the spectral weight expected for the relevant number of carriers and single particle bandmass. We argue that these features are characteristic of a nearly one-dimensional half- or quarter-filled band with Coulomb correlations, and evaluate the finite energy mode in terms of a one-dimensional Mott insulator. At high frequencies (\hbarω> t_\perp, the transfer integral perpendicular to the chains), the frequency dependence of the optical conductivity σ_1(ω) is in agreement with calculations based on an interacting Tomonaga-Luttinger liquid, and is different from what is expected for an uncorrelated one-dimensional semiconductor. The zero frequency mode shows deviations from a simple Drude response, and can be adequately described with a frequency dependent mass and relaxation rate.

description: Van der Waals (vdW) and Casimir interactions depend crucially on material properties and geometry, especially at molecular scales, and temperature can produce noticeable relative shifts in interaction characteristics. Despite this, common treatments of these interactions ignore electromagnetic retardation, atomism, or contributions of collective mechanical vibrations (phonons) to the infrared response, which can interplay with temperature in nontrivial ways. We present a theoretical framework for computing electromagnetic interactions among molecular structures, accounting for their geometry, electronic delocalization, short-range interatomic correlations, dissipation, and phonons at atomic scales, along with long-range electromagnetic interactions among themselves or in the vicinity of continuous macroscopic bodies. We find that in carbon allotropes, particularly fullerenes, carbyne wires, and graphene sheets, phonons can couple strongly with long-range electromagnetic fields, especially at mesoscopic scales (nanometers), to create delocalized phonon polaritons that significantly modify the infrared molecular response. These polaritons especially depend on the molecular dimensionality and dissipation, and in turn affect the vdW interaction free energies of these bodies above a macroscopic gold surface, producing nonmonotonic power laws and nontrivial temperature variations at nanometer separations that are within the reach of current Casimir force experiments.

description: Nowadays, the needs and requirements to avoid infections during surgical operations, require to be more imaginative than ever. The one-use textiles substrates that are used in hospitals can be, also, a way to transport the antibacterial effect around the own building. This is the main objective of this work; to use clothes and textiles surfaces as antibacterial systems using natural components. Microencapsulation has shown in several occasions the effectivity to protect and vehiculize active principles that can be used for medical treatments. In this case, essential oils have been used as antimicrobial agent, that when combined with shell polymers based on Chitosan of different molecular weight distribution and Arabic gum, allows them to act against Gram (+) and Gram (−) bacteria. Chitosan has been shown to be a biopolymer with a wide range of applications and is highly dependent on its molecular weight. The study of the efficiency of the final systems obtained present high valuable possibilities, due to its character similar to hydrogels. The influence of the molecular weight of biopolymers used, in a layer by layer approach (LbL), has been demonstrated and shows a very promising way to state a clear control on the delivery mechanisms. The essential oil used has a very volatile character formed by more than 40 components and with the help of FT-IR and TGA it has been possible to corroborate that all its components were encapsulated. The impregnation of the different samples to the tissue was successful and allowed the antibacterial study to be carried out, which was carried out in duplicate on each sample and demonstrated that they have bacterial activity.

description: Quantum and thermal behaviors of low-dimensional mixed-spin systems are investigated with particular emphasis on the design of molecule-based ferromagnets. One can obtain a molecular ferromagnet by assembling molecular bricks so as to construct a low-dimensional system with a magnetic ground state and then coupling the chains or the layers again in a ferromagnetic fashion. Two of thus-constructed quasi-one-dimensional bimetallic compounds are qualitatively viewed within the spin-wave treatment, one of which successfully grows into a bulk magnet, while the other of which ends in a singlet ground state. Then, concentrating on the ferrimagnetic arrangement on a two-leg ladder which is well indicative of general coupled-chain ferrimagnets, we develop the spin-wave theory and fully reveal its low-energy structure. We inquire further into the ferromagnetic aspect of the ferrimagnetic ladder numerically calculating the sublattice magnetization and the magnetic susceptibility. There exists a moderate coupling strength between the chains in order to obtain the most ferromagnetic ferrimagnet.

Quantization of Gravitational Waves and Squeezing

Year: 1999
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The question whether gravitational waves are quantised or not can in principle be answered by the help of correlation measurements. If the gravitational waves are quantised and they are generated by the change of the background metrics then they can be in squeezed state. In a sqeezed state there is a correlation between the phase of the wave and the quantum fluctuations. It is recommended to analyse the data to be obtained by the gravitational detectors from the point of view of such correlations. An explicit formula is derived for the squeezing parameter of the quantised gravitational waves. The head on collision of two identical black holes is analysed as a possible source of squeezed gravitational waves.

description: The Knight shift of Ga-71 nuclei is measured in two different electron-doped multiple quantum well samples using optically pumped NMR. These data are the first direct measurements of the electron spin polarization, P(nu,T)=/max, near nu=1/3. The P(T) data at nu=1/3 probe the neutral spin-flip excitations of a fractional quantum Hall ferromagnet. In addition, the saturated P(nu) drops on either side of nu=1/3, even in a Btot=12 Tesla field. The observed depolarization is quite small, consistent with an average of about 0.1 spin-flips per quasihole (or quasiparticle), a value which does not appear to be explicable by the current theoretical understanding of the FQHE near nu=1/3.

The extraction and detection of drugs of abuse from absorbent gel material found in disposable diapers
Creators: name: Quinter, Alexis
Publisher: name: No Publisher Supplied
Year: 2021

description: Over the past 25 years, there has been research performed on recovering analytes from disposable diapers. Predominantly, there are two methods which are using methanol as a solvent and using calcium chloride; while both methods have shown to recover analytes from disposable diapers there has not been a study comparing the two methods determining which is optimal for scientists to utilize. Analytical methods were evaluated for detecting MDMA, diazepam, oxycodone, fentanyl and internal standard, mirtazapine, in urine and extracts from the absorbent gel material in disposable diapers by gas chromatography/mass spectrometry (GC/MS). MDMA, diazepam, oxycodone, and fentanyl were extracted from urine-soaked diapers using two previously published methods. Half of the samples were immersed in methanol, which was evaporated before reconstituting in drug-free urine and extracted on a solid phase extraction column. Half of the samples had CaCl2 powder added directly to them, which released urine and analytes from the polymer and the liquid was extracted on a solid phase extraction column. Both methods are suitable for extracting the analytes from the disposable diaper although diazepam and fentanyl had better recoveries with the methanol method. However, oxycodone oscillated between both methods, recovering better with the methanol method during the shorter time periods and recovering better with the CaCl2 method during the longer time periods. Extracting immediately after addition to the diaper, diazepam could be positively identified at lowest concentration of 25ng/mL, fentanyl could be positively identified at lowest concentration of 50ng/mL, and MDMA and oxycodone could be positively identified at lowest concentration of 500ng/mL. Concentrations of 50ng/mL diazepam, 450ng/mL fentanyl and 4,500ng/mL oxycodone could be detected and positively identified up to 24 days in the disposable diapers stored in the refrigerator. Analysis by GC/MS of MDMA, diazepam, oxycodone, fentanyl, and mirtazapine extracted from diapers provide a suitable alternative to collection of urine, which is difficult in non-toilet trained individuals.

description: One of the great advantages of electrospun fibers is the large tridimensional area produced, capable of storing any type of material. The aim of our investigation is to study the electrospinning technique to produce polymer membranes for drug delivery applications, given their large surface area and ability to transport a bioactive compound. A mathematical modeling of the delivery system kinetics was also studied to find the mechanism that controls the releasing process. Results showed that electrospinning could provide regular and smooth membranes suitable for drug delivery processes. The choice of a proper solvent for this process was an important parameter analyzed, because it determined whether fibers were capable of forming, as well as influencing fiber porosity. The mathematical modeling also proved that thicker PLLA membranes exhibited a Fickian diffusion behavior during the drug transport, presenting better control in drug delivery processes.

description: From formal and practical analysis, we identify new challenges that self-adaptive systems pose to the process of quality assurance. When tackling these, the effort spent on various tasks in the process of software engineering is naturally re-distributed. We claim that all steps related to testing need to become self-adaptive to match the capabilities of the self-adaptive system-under-test. Otherwise, the adaptive system's behavior might elude traditional variants of quality assurance. We thus propose the paradigm of scenario coevolution, which describes a pool of test cases and other constraints on system behavior that evolves in parallel to the (in part autonomous) development of behavior in the system-under-test. Scenario coevolution offers a simple structure for the organization of adaptive testing that allows for both human-controlled and autonomous intervention, supporting software engineering for adaptive systems on a procedural as well as technical level.

subject: FOS: Physical sciences

description: Among about 1.8 million Gaia DR2 high proper motion stars with $μ>60$ mas/yr and moderately significant parallaxes ($\varpi>3σ_{\varpi}$), we have selected 109 high-speed star candidates with Galactic rest frame tangential velocities (corrected for solar motion) $v_{t,g}$$>$700 km/s, well above the local Galactic escape velocity. After applying various Gaia DR2 astrometric quality criteria, only 39 candidates remained, including all three hypervelocity runaway white dwarfs (HVR WDs) found by Shen et al. (2018) but no additional such candidates (falling in the same region of the colour-magnitude diagram). Considering only candidates with highly significant parallaxes ($\varpi>5σ_{\varpi}$) as reliable extreme tangential velocity candidates (cf. Bromley et al. 2018), our final list consists of six objects with parallaxes of 0.17 mas $\lesssim \varpi \lesssim$ 1.05 mas and tangential velocities of 730 km/s $\lesssim v_{t,g} \lesssim$ 1600 km/s, including two candidates of Bromley et al. (2018). Only one of the three HVR WDs of Shen et al. (2018), D6-2 (= NLTT 51732), falls in that list but can be considered a doubtful high-speed candidate because of its relatively large astrometric quality parameters. One of the three new extreme velocity candidates in our list, Gaia DR2 6097052289696317952, is relatively bright ($G\approx$13.5 mag) and blue $BP$$-$$RP$$\approx$0.6 mag and has the smallest parallax and highest tangential velocity. Radial velocity measurements are needed to clarify whether these high-speed candidates are unbound to the Galaxy.

description: Demand for reliable data remains a major issue in training machine learning models in computer vision. Frequently, datasets are of insufficient scale, imbalanced, not diverse, and of poor quality, potentially resulting in biased, inaccurate, non-robust, and badly generalizing models. Moreover, realworld training data can raise privacy concerns or be extremely expensive to gather, necessitating alternative solutions. This paper investigates the use of diffusion models for generative data augmentation in semantic image segmentation, specifically in the domain of vehicle damage detection. We propose a new approach that utilizes an existing diffusion model ControlNet to generate useful synthetic data depicting realistic vehicles with damages such as scratches, rim damages, dents and etc. Based on this we provide an analysis and show how such a generative data augmentation may help in scenarios where training data is scarce and of low quality.

description: A systematic theoretical study of stoichiometric clusters (NaI)n up to n=15 is performed using the ab initio Perturbed-Ion (PI) model. The structures obtained are compared to previous pair potential results, and observed differences between (NaI)n clusters and previous ab initio results for other alkali halide clusters are discussed. (NaI)n clusters with n up to 15 do not show yet a marked preference for geometries which are fragments of the bulk lattice. Instead, stacks of hexagonal rings or more open structures are obtained as ground structures in clusters with n=3, 6, 7, 9, 10, 12, 13 and 15, indicating that convergence to bulk structure is not achieved yet at this size range. Low lying isomers which are fragments of the crystal lattice exist, nevertheless, for those cases. The binding energies show that clusters with n=(4), 6, 9 and 12 molecules are specially stable. The binding energy has been decomposed in contributions which allow for an intuitive interpretation. Some electronic properties like ionization potentials and electronic energy levels are also studied.

Half-metallicity in quaternary Heusler alloys with 3$d$ and 4$d$ elements: observations and insights from DFT calculations

description: In this work, we provide important insights into the evolution of half-metallicity in quaternary Heusler alloys. Employing {\it ab initio} electronic structure methods we study 18 quaternary Heusler compounds having the chemical formula CoX$^\prime$Y$^\prime$Al, where Y$^\prime$ = Mn, Fe; and X$^\prime$ a 4$d$ element. Along with the search for new materials for spintronics applications, the trends in structural, electronic, magnetic properties and Curie temperature were investigated. We have made comparative studies with the compounds in the quaternary series CoX$^{\prime}$Y$^{\prime}$Si with X$^{\prime}$ materials from 3$d$ and 4$d$ transition metal series in the periodic table. We observe that the half-metallic behaviour depends primarily on the crystal structure type based on atomic arrangements and the number of valence electrons. As long as these two are identical, the electronic structures and the magnetic exchange interactions bear close resemblances. Consequently, the materials exhibit identical electronic properties, by and large. We analysed the roles of different transition metal atoms in affecting hybridisations and correlated them with the above observations. This work, therefore, provides important perspectives regarding the underlying physics of half-metallic behaviour in quaternary Heusler compounds which goes beyond specifics of a given material. This, thus, paves way for smart prediction of new half-metals. This work also figures out an open problem of understanding how different ternary Heuslers with different electronic behaviour may lead to half-metallic behaviour in quaternary Heuslers with 4$d$ transition metal elements.

Constructing production flow visualizations can be difficult and time-consuming, and has often involved expensive simulation software. In this paper we describe successful work populating NIST CMSD Core Manufacturing Simulation Data from existing factory data, visualizing factory flows using the open source D3.js visualization toolset. By mapping existing factory test data using the CMSD standard, the open source visualization toolset represents a lower-cost mechanism for understanding and optimizing test operations, detailed in this paper. The visualization was developed with a small team and deployed into production at a large aerospace manufacturer over the course of four months and is now used by multiple business units for factory flow optimizations of their complex engineered products.X

description: We have used the stabilized spin-polarized jellium model to calculate the equilibrium sizes of metal clusters. Our self-consistent calculations in the local spin-density approximation show that for an $N$-electron cluster, the equilibrium is achieved for a configuration in which the difference in the numbers of up-spin and down-spin electrons is zero or unity, depending on the total number of electrons. That is, a configuration in which the spins are maximally compensated. This maximum spin-compensation results in both the alternation in the average distance between the nearest neighbor ions and the odd-even alternations in the ionization energies of alkali metal clusters, in a good agreement with the molecular dynamics findings and the experiment. These suggest a realistic and more accurate method for calculating the properties of metal clusters in the context of jellium model than previous jellium model methods.

description: Several studies have proposed constraints under which a low dimensional representation can be derived from large-scale real-world networks exhibiting complex nonlinear dynamics. Typically, these representations are formulated under certain assumptions, such as when solutions converge to attractor states using linear stability analysis or using projections of large-scale dynamical data into a set of lower dimensional modes that are selected heuristically. Here, we propose a generative framework for selection of lower dimensional modes onto which the entire network dynamics can be projected based on the symmetry of the input distribution for a large-scale network driven by external inputs, thus relaxing the heuristic selection of modes made in the earlier reduction approaches. The proposed mode reduction technique is tractable analytically and applied to different kinds of real-world large-scale network scenarios with nodes comprising of a) Van der Pol oscillators b) Hindmarsh-Rose neurons. These two demonstrations elucidate how order parameter is conserved at original and reduced descriptions thus validating our proposition.

Subjects: Customs, VAT, Income Tax Article 22, Export, Import.

description: Abstract

This research aims to evaluate the realization of customs receipts, customs acceptance targets, and value-added tax and income tax receipts Article 22. The data used in this research were secondary data from monthly reports on customs receipts and taxes in the context of imports (VAT and Income Tax Article 22) in the 2014 - 2018 period and primary data from interviews with related parties. This research used a quantitative descriptive analysis method. The research results show that customs receipts received by Ternate's KPPBC TMP C from 2014 - 2018 each year experienced increased fluctuations annually, both in terms of imports and exports. However, from the KPPBC TMP C, Ternate itself was still able to maintain consistency with customs revenue from targets given and shows the achievements that each year increases with different export and import trends. For the receipt of VAT and Income Tax Article 22, Ternate's KPPBC TMP C collection has helped collect tax revenues in export and import activities, thereby increasing state revenues. The fluctuations in customs receipts and taxes are caused by several factors, including the volume/export quota, import duties, purchasing power/buying interest, administration, religious celebrations, and government regulations.

description: Abstract

This research article investigates the impact of women entrepreneurship on digital entrepreneurship in Bangladesh, aiming to analyze the role of women in the evolving digital landscape. The study identifies critical challenges faced by women entrepreneurs in accessing digital opportunities, assesses the current state of digital entrepreneurship, and examines the facilitators and barriers to women's participation. Utilizing a mixed-methods approach, the study incorporates quantitative data from a survey of 50 women entrepreneurs, predominantly from Dhaka, Narayanganj, and Gazipur, alongside qualitative insights from in-depth interviews. Key findings reveal significant obstacles such as limited access to finance, insufficient training, and cultural constraints that hinder women’s entrepreneurial ventures. Despite an increase in women-led businesses, only 7.2% of enterprises in Bangladesh are owned by women, with a concentration in sectors like handicrafts and garments. The study underscores the need for targeted strategies to enhance women's engagement in digital entrepreneurship, including improved access to financial resources, tailored training programs, and supportive policies. By addressing the multifaceted challenges identified, this research aims to contribute to the economic empowerment of women in Bangladesh, ultimately fostering greater participation in the digital economy and promoting sustainable development.

Impact of Metal ns2 Lone Pair on Luminescence Efficiency in Low-Dimensional Halide Perovskites

description: Based on first-principles calculations, we show that chemically active metal ns2 lone pairs play an important role in exciton relaxation and dissociation in low-dimensional halide perovskites. We studied excited-state properties of several recently discovered luminescent all-inorganic and hybrid organic-inorganic zero-dimensional (0D) Sn and Pb halides. The results show that, despite the similarity in ground-state electronic structure between Sn and Pb halide perovskites, the chemically more active Sn2+ lone pair leads to stronger excited-state structural distortion and larger Stokes shift in Sn halides. The enhanced Stokes shift hinders excitation energy transport, which reduces energy loss to defects and increases the photoluminescence quantum efficiency (PLQE). The presence of the ns2 metal cations in the 0D halide perovskites also promotes the exciton dissociation into electron and hole polarons especially in all-inorganic compounds, in which the coupling between metal-halide clusters is significant.

description: Borate glasses containing Li2O and fixed concentration of heavy metal oxide Bi2O3 are prepared by melt quenching technique. The effect of addition of Li2O on borobismuthate glasses has been studied. Density of the glasses has been found to increase slightly with Li2O content whereas molar volume and glass transition temperature decreases. IR spectroscopy was used for structural studies of these glasses in the range from 400 to 4000 cm−1. IR analysis showed that Bi3+cations are incorporated in the glass structure as (BiO6) octahedral units and boron ions are incorporated as (BO3) and (BO4) units. As the Li2O content increases in the glass, some of the BO3 trigonal units get converted into BO4 tetrahedral units and non-bridging oxygens have been formed. The optical transmittance spectra have been recorded at room temperature. The cut-off wavelength shows a red shift, the optical band gap decreases and polarizability increases with Li2O content. The compositional dependence of different physical properties such as density, molar volume optical band gap and optical basicity has been studied and correlated with the glass structure.
