description: We present a general framework of examining the validity of weak measurement -- the standard procedure to acquire Aharonov's weak value -- which has been used intensively in recent years for precision measurement, taking advantage of the amplification mechanism available for the weak value. Our framework allows one to deal systematically with various causes of uncertainties intrinsic to the actual measurement process as well as those found in the theoretical analysis employed to describe the system. Using our framework, we examine in detail the two seminal experiments, Hosten's detection measurement of the spin Hall effect of light and Dixon's ultra sensitive beam deflection measurement. Our analysis shows that their results are well within the range of amplification (actually in the vicinity of the optimal point) where the weak measurements are valid. This suggests that our framework is both practical and sound, and may be useful to determine beforehand the possible extent of amplification in the future weak measurement experiments.

description: The results of wind-tunnel investigation of twin-engine medium short takeoff and landing transport (MSTOL) model with the external blown flap (EBF) by exhaust flows of turbofan simulators are presented. The main features of exhaust blowing influence on aerodynamic characteristics of the model in takeoff, landing and cruising configurations are considered. The obtained values of lift coefficient of twin-engine model are close to according values of four-engine model. Thereby the experimental studies have shown the possibility of using the EBF to achieve the increased lift, required to provide the short takeoff and landing (STOL) capability for twin-engine transport aircraft.

description: The control of materials at the microstructural level is critical for the aerospace sector: the properties of their components are governed by microstructural features usually design with great precision. This is especially the case for Ni-based superalloy, a class of materials used in high-temperature aerospace components. In this work we present an image analysis framework based on open-source software to quantify precisely and efficiently the different microstructural properties of a set of commercial Nibased superalloys (Inconel-718, HasteloyX, Rene77 and Inconel-738). The framework is then used to investigate the failure cause of an aerospace component: an auxiliary power unit.

description: We have performed classical molecular dynamics simulation of $Ar_{13}$ cluster to study the behavior of collective excitations. In the solid ``phase'' of the cluster, the collective oscillation of the monopole mode can be well fitted to a damped harmonic oscillator. The parameters of the equivalent damped harmonic oscillator-- the damping coefficient, spring constant, time period of oscillation and the mass of the oscillator -- all show a sharp change in behavior at a kinetic temperature of about $7.0^oK$. This marks yet another characteristic temperature of the system, a temperature $T_s$ below which collective excitations are very stable, and at higher temperatures the single particle excitations cause the damping of the collective oscillations. We argue that so long as the cluster remains confined within the global potential energy minimum the collective excitations do not decay; and once the cluster comes out of this well, the local potential energy minima pockets act as single particle excitation channels in destroying the collective motion. The effect is manifest in almost all the physical observables of the cluster.

The overall goal is to reach TRL 5-6 for the chosen technologies by hot-fire testing in fullscale at P3.2 in Lampoldshausen, Germany. The paper will present the outcomes of the hot-fire test campaign conducted between June 2018 and March 2019. A total of 23 hot fire test days have been performed on 4 different hardware configurations. A cumulated runtime of 2707sec distributed across more than 40 operating points has been achieved on the test articles. The demonstrator hardware consists of a thrust chamber assembly (TCA) and three different electro-driven rocket engine valve types.

description: We study Pontecorvo neutrino-antineutrino oscillations both in vacuum and in matter within a field theoretic approach, showing that this phenomenon can occur only if neutrinos have a Dirac-Majorana mass term. We find that matter effects suppress these oscillations and cannot explain the solar neutrino problem. On the contrary, a vacuum neutrino-antineutrino oscillations solution to this problem exists. We analyze this solution and available data from laboratory experiments giving stringent limits on $ν_e$ and $ν_μ$ Majorana masses.

description: The paper considers the problem of anomaly detection in 3D images of fibre materials. The spatial Stochastic Expectation Maximisation algorithm and Adaptive Weights Clustering are applied to solve this problem. The initial 3D grey scale image was divided into small cubes subject to clustering. For each cube clustering attributes values were calculated: mean local direction and directional entropy. Clustering is conducted according to the given attributes. The proposed methods are tested on the simulated images and on real fibre materials.

description: We show that a quantum Hall bilayer with the total filling $ν= 1$ should exhibit a dynamical regime similar to the flux-flow in large Josephson junctions. This analogy may explain a conspicuous peak in the interlayer tunneling conductance [\prl {\bf 84}, 5808 (2000)]. The flux-flow is likely to be spatiotemporally chaotic at low bias voltage, which will manifest itself through broad-band noise. The peak position can be controlled by an in-plane magnetic field.

description: We report pair distribution function measurements of the iron-based superconductor FeSe above and below the structural transition temperature. Structural analysis reveals a local orthorhombic distortion with a correlation length of about 4 nm at temperatures where an average tetragonal symmetry is observed. The analysis further demonstrates that the local distortion is larger than the distortion at temperatures where the average observed symmetry is orthorhombic. Our results suggest that the low-temperature macroscopic nematic state in FeSe forms from an imperfect ordering of orbital-degeneracy-lifted nematic fluctuations which persist up to at least 300 K.

description: We investigate a t-J ladder model by numerical diagonalization method. By calculating correlation functions and assuming the Luttinger liquid relation, we obtained a possible phase diagram of the ground state as a function of J/t and electron density $n$. We also found that behavior of correlation functions seems to consist with the prediction of Luttinger liquid relation. The result suggests that the superconducting phase appear in the region of $J/t \displaystyle{ \mathop{>}_{\sim}} 0.5$ for high electron density and $J/t \displaystyle{ \mathop{>}_{\sim}} 2.0$ for low electron density.

description: We study plasmon propagation on a metallic two-dimensional surface partially coated with a thin film of anomalous-Hall material. The resulting three regions, separated by two sharp interfaces, are characterised by different Hall conductivities but identical normal conductivities. A single bound mode is found, which can localise to either interface and has an asymmetric potential profile across the region. For propagating modes, we calculate the reflection and transmission coefficients through the magnetic region. We find Airy transmission patterns with sharp maxima and minima as a function of the plasmon incidence angle. The system therefore behaves as a high-quality filter.
description: 11 pages, 7 figures. Upon revision, the basic content and analysis of the paper is unchanged but the emphasis on topological insulators has been removed. The title and abstract has been changed to reflect this. Damping of the bound mode has been included

description: Recently, the Gaia data release 2 (DR2) showed us the richness in the kinematics of the Milky Way disk. Of particular interest is the presence of ridges covering the stellar velocity distribution, $V_ϕ-R$; as shown by others, it is likely that these ridges are the signature of phase mixing, transient spirals, or the bar. Here, with a Galactic model containing both: bar and spirals, we found the same pattern of ridges extending from the inner to the outer disk. Interestingly, ridges in the $V_ϕ-R$ plane correlate extremely well with wiggles in the computed rotation curve (RC). Hence, although the DR2 reveals (for the first time) such substructures in a wide spatial coverage, we notice that we have always seen such pattern of ridges, but projected into the form of wiggles in the RC. The separation and amplitude of the wiggles strongly depend on the extension and layout of ridges in the $V_ϕ-R$ plane. This means that within the RC are encoded the kinematic state of the disk as well as information about the bar and spiral arms. The amplitude of the wiggles suggests that similar features currently observable in external galaxies RCs have similar origins, triggered by spirals and bars.

description: The EOPA aircraft is a tandem tilt-wing design capable of vertical take-off and landing. Essential to its operation is the ability to transition from powered-lift to fixed-wing flight, and vice-versa. Control of the transition maneuver is achieved by designing a nominal transition trajectory and using a gain-scheduled LQR to realize closed-loop control. Controller robustness to wind gusts is investigated. Methods used for the dynamic and aerodynamic modelling are described. Simulation results demonstrate the feasibility of closed-loop control of the transition maneuvers but also reveal a susceptibility to wind gusts encountered during transition.
QCD Sum Rules for the Isospin-Breaking Axial Correlator with Correct Chiral Behavior

description: We revisit the QCD sum-rule treatment of the isospin-breaking axial correlator in light of the recent claim that a previous treatment produced results incompatible with known chiral constraints. The source of the error in the previous analysis is identified, and a corrected version of the sum-rule treatment obtained. It is then shown that, using input from chiral perturbation theory, one may use the resulting sum rule to extract information on the leading chiral behavior of isospin-breaking parameters associated with the coupling of excited pseudoscalar resonances to the axial currents. A rather accurate extraction is possible for the case of the eta'. Demanding stability of the sum-rule analysis also allows us to improve the upper bound on the fourth-order low-energy constant, L_7.

description: Exploring the Intersection of Mathematical Physics, Quantum Mechanics, and Astrophysics: A Unified Perspective
This thesis presents a comprehensive exploration of the core principles underpinning mathematical physics, quantum mechanics, and astrophysics, aiming to bridge gaps between micro and macro-scale phenomena in the universe. The research delves into the mathematical structures that govern quantum field theory, the complexities of wave-particle duality, and the behavior of subatomic particles, extending these principles to celestial bodies and cosmic phenomena.
A significant focus is placed on the nature of quantum entanglement, spacetime curvature, and the evolving understanding of dark matter and dark energy. Using a combination of analytical models, computational simulations, and theoretical frameworks, the thesis investigates how quantum phenomena influence larger astrophysical structures and cosmic evolution.
Further, this research proposes new interpretations of quantum gravity and the potential for unified field theories, drawing on interdisciplinary methodologies that connect quantum computing, cosmology, and high-energy physics.
This work aims to contribute to the ongoing dialogue in physics, offering fresh insights into the connections between quantum and cosmic realms while opening pathways for future exploration in both theoretical and applied physics.

description: We study an EUV confined ejection observed on 09 May 2012 in active region (AR) NOAA 11476. For the analysis we use observations in multiple wavelengths (EUV, X-rays, H$α$, and magnetograms) from a variety of ground-based and space instruments. The magnetic configuration showed the presence of two rotating bipoles, with decreasing magnetic flux, within the following polarity of the AR. This evolution was present along some tens of hours before the studied event and continued even later. A minifilament with a length of $\approx 30 \arcsec$ lay along the photospheric inversion line of the largest bipole. The minifilament was observed to erupt accompanied by an M4.7 flare (SOL20120509T12:23:00). Consequently, dense material, as well as twist, was injected along closed loops in the form of a very broad ejection whose morphology resembles that of typical H$α$ surges. We conclude that the flare and eruption can be explained as due to two reconnection processes, one occurring below the erupting minifilament and another one above it. This second process injects the minifilament plasma within the reconnected closed loops linking the main AR polarities. Analyzing the magnetic topology using a force-free model of the coronal field, we identify the location of quasi-separatix layers (QSLs), where reconnection is prone to occur, and present a detailed interpretation of the chromospheric and coronal eruption observations. In particular, this event, contrary to what has been proposed in several models explaining surges and/or jets, is not originated by magnetic flux emergence but by magnetic flux cancellation accompanied by the rotation of the bipoles. In fact, the conjunction of these two processes, flux cancellation and bipole rotations, is at the origin of a series of events, homologous to the one we analyze in this article, that occurred in AR 11476 from 08 to 10 May 2012.

description: We present a comprehensive study of the lattice restricted primitive model, i.e., a lattice gas consisting of an equal number of positively and negatively charged particles interacting via on-site exclusion and a 1/r potential. On the cubic lattice, Monte Carlo simulations show a line of Neel points separating a disordered, high-temperature phase from a phase with global antiferromagnetic order. At low temperatures the (high-density) ordered phase coexists with the (low-density) disordered phase. The Neel line meets the coexistence curve at a tricritical point, T_t \simeq 0.14, rho_t \simeq 0.4. A simple mean-field analysis is in qualitative agreement with simulations.

description: UGC 10214 is a minor merger in which a dwarf galaxy has interacted with a large spiral galaxy $\sim$250 Myr ago and produced a perturbed disk and a giant tidal tail. We use a multiwavelength dataset in order to study the present and past star formation rate (SFR) and its relation to the gas and stellar mass at a spatial resolution down to 4 kpc. UGC 10214 is a very massive (stellar mass $M_{\rm \star}$ = $1.28\times 10^{11}$$M_\odot$) galaxy with a low gas fraction ($M_{\rm gas}$/$M_{\rm \star}$ = 0.24), a high molecular gas fraction ($M_{{\rm H}_2}$/$M_{\rm HI}$ = 0.4) and a modest SFR (2-5 $M_\odot$ yr$^{-1}$). The comparison of the molecular gas mass and current SFR gives a molecular gas depletion time of about $\sim$ 2 Gyr (based on H$α$), comparable to those of normal spiral galaxies. Both from a comparison of the H$α$ emission, tracing the current SFR, and far-ultraviolet (FUV) emission, tracing the recent SFR during the past tens of Myr, as well as from spectral energy distribution (SED) fitting with CIGALE, we find that the SFR has increased by a factor of about 2-3 during the recent past. This increase is particularly noticeable in the centre of the galaxy. A pixel-to-pixel comparison of the SFR, molecular gas mass and stellar mass shows that the central region has had a depressed FUV-traced SFR, both compared to the molecular gas and the stellar mass, whereas the H$α$-traced SFR shows a normal level. The atomic and molecular gas distribution is asymmetric, but the position-velocity diagram along the major axis shows a pattern of regular rotation. We conclude that the minor merger has most likely caused variations in the SFR in the past resulting in a moderate increase of the SFR, but it has not perturbed the gas significantly so that the molecular depletion time remains normal.

description: Hirschsprung disease (HSCR) is a gastrointestinal neuropathy that affects 1 in 5000 newborns annually. While most patients respond well to corrective surgery, up to half will develop Hirschsprung associated enterocolitis (HAEC) within 12 months. HAEC is the leading cause of morbidity and mortality in these patients. This thesis provides a comprehensive characterisation of the immune cell populations within the gut wall of HSCR patients and non-HSCR controls to determine the composition, frequency and spatial location of these key cellular populations.

LARGE EDDY SIMULATION
BOUNDARY LAYERS

description: The flow pattern in over-expanded conical nozzles is numerically investigated by means of threedimensional wall-modeled large-eddy simulations (WM-LES). The objective of the study is to identify the origin of the low-frequency oscillations (LFO) and the side-loads generation observed in separated supersonic flows. The computational results are compared with the available experimental data for validation. The simulations bring clear evidence of the existence of broadband and energetically-significant LFO in the vicinity of the separated shock. The magnitude of the shock excursions was less important in the conical case, compared to the planar nozzle, because of the strong adverse pressure gradient that develops upstream of the separation zone. The generated side-loads were analyzed and a dynamic mode decomposition (DMD) analysis reveals the existence of two types of modes: the non-helical modes which are low-frequency modes based mainly in the streamwise forces and the helical modes which are highfrequencies modes, compared to the first Type. The laters mainly concern the side-loads.

description: The phytochemical study of the fruits of Melia azedarach (Meliaceae) led to the isolation and characterisation of two novel natural limonoids1-deoxy- 3, 20-dicinnamoyl-11-methoxy-meliacarpinin (1) and 12β- O- methyl nimbolinin A (2), along with twelve known limonoids. Its structure was identified by 1D- and 2D-NMR, HR-ESI-MS and comparison with published data. The anti-inflammatory effect of the compounds was measured in vitro in RAW 264.7 cells by evaluating the production of NO stimulated by LPS. Compounds 1, 8 and 14 indicated significant anti-inflammatory effect with inhibition rate of 11.76, 8.45 and 6.59 μM, respectively. Limonoid 1 significantly inhibited the production of NO, TNF-α and IL-1β in RAW 264.7 cells. Therefore, limonoid derivative may be a promising source of bioactive metabolite for inflammatory diseases.

description: Interest in magnetic-tunnel junctions has prompted a re-examination of tunneling measurements through thin insulating films. In any study of metal-insulator-metal trilayers, one tries to eliminate the possibility of pinholes (small areas over which the thickness of the insulator goes to zero so that the upper and lower metals of the trilayer make direct contact). Recently, we have presented experimental evidence that ferromagnet-insulator-normal trilayers that appear from current-voltage plots to be pinhole-free may nonetheless in some cases harbor pinholes. Here, we show how pinholes may arise in a simple but realistic model of film deposition and that purely classical conduction through pinholes may mimic one aspect of tunneling, the exponential decay in current with insulating thickness.

Inverse Compton Scattering Spectra of Gamma-Ray Burst Prompt Emission

description: Although the physical origin of gamma-ray burst (GRB) prompt emission is still controversial, synchrotron radiation from accelerated electrons is a promising mechanism. It is believed that electrons are accelerated continuously by ultra-relativistic shocks or magnetic reconnections. At the same time, these electrons will be cooled via several processes (mainly adiabatic expansion, synchrotron radiation and inverse Compton scattering (ICS)), which regulate the distribution of electrons. An extra high-energy spectrum component is expected to be induced by ICS. However, the gamma-gamma annihilation effect may eliminate the high-energy photons and prevent the observers from distinguishing the extra component. We perform numerical calculations by taking these effects into account and discuss whether the extra ICS component could be observed. By exploring the plausible parameter space for relevant quantities of the GRB ejecta, we present the electron distributions and the corresponding spectra of synchrotron radiation and ICS. It is found that the extra component is observable only for ejecta with a rather large bulk Lorentz factor. A large Lorentz factor means the adiabatic expansion is the leading process in the electron cooling procedure, which makes the low-energy electron distribution spectrum to be relatively hard. Therefore the ICS component is more likely to be detected for GRBs that have a hard low-energy photon spectrum.

description: We present the public release version of relxill_nk, an X-ray reflection model for testing the Kerr hypothesis and general relativity. This model extends the relxill model that assumes the black hole spacetime is described by the Kerr metric. We also present relxilllp_nk, the first non-Kerr X-ray reflection model with a lamppost corona configuration, as well as all other models available in the full relxill_nk package. In all models the relevant relativistic effects are calculated through a general relativistic ray-tracing code that can be applied to any well-behaved, stationary, axisymmetric, and asymptotically flat black hole spacetime. We show that the numerical error introduced by using a ray-tracing code is not significant as compared with the observational error present in current X-ray reflection spectrum observations. In addition, we present the reflection spectrum for the Johannsen metric as calculated by relxill_nk.

description: Direct Numerical Simulations of two superposed fluids in a channel with a textured surface on the lower wall have been carried out. A parametric study varying the viscosity ratio between the two fluids has been performed to mimic both {\bf idealised} super hydrophobic and liquid infused surfaces and assess its effect on the frictional, form and total drag for three different textured geometries: longitudinal square bars, transversal square bars and staggered cubes. The interface between the two fluids is assumed to be slippery in the streamwise and spanwise directions and not deformable in the vertical direction, corresponding to the ideal case of infinite surface tension. To identify the role of the fluid-fluid interface, an extra set of simulations with a single fluid has been carried out and compared to the results obtained with two fluids of same viscosity separated by the interface. The drag and the maximum wall-normal velocity fluctuations were found to be highly correlated for all the surface configurations, whether they reduce or increase the drag. This implies that the structure of the near-wall turbulence is dominated by the total shear and not by the local boundary condition of super-hydrophobic, liquid--infused or rough surfaces.

description: Background: While lower body exercises have been well quantified for bone health programs, upper body exercises lack quantification. Purpose: This study aimed to quantify and assess the reliability of a modified push up drop exercise at different rates of perceived exertion (RPE) in premenopausal women. Methods: Twenty-two women (Mean ± SD: 33.1 ±10.0 years; 64.6 ±9.2kg; 163.8 ±5.9cm) performed modified push up drops on VALD ForceDecks at RPEs of 4, 7, and 10. To assess between-session reliability, testing was repeated 3-days later. Results: The modified push up drop exceeded the previously determined osteogenic rate of force threshold (43BW·s-1) in all RPE conditions (101.7 to 225.7BW·s-1), but only the RPE 10 condition (2.81BW’s) approached the previously determined magnitude of force threshold (3BW’s). Significant main effects (p<0.001) were observed for peak vertical force and peak rate of force development across the RPE conditions. Within-session reliability was moderate to good (ICC 0.5 to 0.76) for all RPE conditions, except for RPE 10, which showed excellent reliability for peak vertical force (ICC 0.9). Between-session reliability was poor (ICC -0.37 to 0.38) for all RPE conditions, except for RPE 4, which showed moderate reliability for peak vertical force (ICC 0.46 and 0.55). Conclusions: The modified push up drop exercise meets osteogenic thresholds necessary for bone growth in premenopausal women and can be reliably autoregulated within sessions. Longitudinal studies are needed to establish upper body thresholds associated with bone remodelling.

Cash Waqf as a Source of Financing for Small Enterprises in Libya (Waqf Microfinance Fund)
Creators: name: Mohamed Idris Bader
Publisher: name: Zenodo
Year: 2024

description: The idea of establishing specialized endowment funds has gained great importance in community service in several countries, in all economic and social sectors and activities where The advantages that distinguish Waqf (endowment) funds have prompted many Islamic countries to adopt them, such as Kuwait, Malaysia, Saudi Arabia, and others, in an attempt to find new renewable resources as alternatives to traditional financing and fill its gaps. Despite the advantages of these funds, Libya is still witnessing deficiencies in the field of endowment and has yet to come close to the idea of cash Waqf funds. This study and its results attempt to be a reference, a model, and a constructive outlook for Libya's adoption of the concept and project of cash endowment funds as an additional funding source along with available financing sources and a solution to the financing problems that small enterprises suffer in Libya. It would also serve as a proposal and vision for the future to activate the Waqf experiment and embody it on the ground.

description: We show that if the solar and atmospheric data are both described by maximal vacuum oscillations at the relevant mass scales then there exists a unique mixing matrix for three neutrino flavors. The solution necessarily conserves CP and automatically implies that there is no disappearance of atmospheric $ν_e$, consistent with indications from the Super-Kamiokande experiment. We also investigate the consequences for three-neutrino mixing if the solar and atmospheric oscillations exhibit mixing that is large but not maximal. For non-maximal mixing $ν_e\leftrightarrowν_τ$ and $ν_e\leftrightarrowν_μ$ oscillations are predicted that may be observable in future long-baseline experiments.
