Axionic Boson Stars in Magnetized Conducting Media

description: Axions are possible candidates of dark matter in the present Universe. They have been argued to form axionic boson stars with small masses $10^{-14}M_{\odot}\sim 10^{-11}M_{\odot}$. Since they possess oscillating electric fields in a magnetic field, they dissipate their energies in magnetized conducting media such as white dwarfs or neutron stars. At the same time the oscillating electric fields generate a monochromatic radiation with energy equal to mass of the axion. We argue that the effect of the energy dissipation can be seen in the old white dwarfs. In particular, We show that colliding with sufficiently cooled white dwarfs, plausible candidates of MACHO, the axionic boson stars dissipate their energies in the dwarfs and heat up the dwarfs. Consequently the white dwarfs in the halo can emit detectable amount of thermal radiations with the collision. On the other hand, the monochromatic radiations can be seen only during the collision; a period of the dwarf passing the axionic boson star. Assuming that MACHO are dark white dwarfs, we show that there is a threshold in luminosity function of the white dwarfs below which the number of the white dwarfs in the halo increase discontinuously. The threshold in the luminosity function is expected to be located around $10^{-5.5}L_{\odot}\sim 10^{-7}L_{\odot}$. Its precise value is determined by the mass of the axionic boson stars dominant in the halo.

description: Recent research in two-dimensional (2D) materials has boosted a renovated interest in the p-n junction, one of the oldest electrical components which can be used in electronics and optoelectronics. 2D materials offer remarkable flexibility to design novel p-n junction device architectures, not possible with conventional bulk semiconductors. In this Review we thoroughly describe the different 2D p-n junction geometries studied so far, focusing on vertical (out-of-plane) and lateral (in-plane) 2D junctions and on mixed-dimensional junctions. We discuss the assembly methods developed to fabricate 2D p-n junctions making a distinction between top-down and bottom-up approaches. We also revise the literature studying the different applications of these atomically thin p-n junctions in electronic and optoelectronic devices. We discuss experiments on 2D p-n junctions used as current rectifiers, photodetectors, solar cells and light emitting devices. The important electronics and optoelectronics parameters of the discussed devices are listed in a table to facilitate their comparison. We conclude the Review with a critical discussion about the future outlook and challenges of this incipient research field.

description: Quantum resources, such as coherence, discord, and entanglement, play as a key role for demonstrating advantage in many computation and communication tasks. In order to find the nature behind these resources, tremendous efforts have been made to explore the connections between them. In this work, we extend the single party coherence resource framework to the distributed scenario and relate it to basis-dependent discord. We show the operational meaning of basis-dependent discord in quantum key distribution. By formulating a framework of basis-dependent discord, we connect these quantum resources, coherence, discord, and entanglement, quantitatively, which leads to a unification of measures of different quantum resources.

description: We study BPS-saturated classical solutions for the world-sheet theory of a D-string in the presence of a point charge. These solutions are interpreted as describing planar 3-string junctions, which arise because the original D-string is deformed by the presence of the inserted charge. We compute the angles of the junctions and show that the vector sum of string tensions is zero, confirming a conjecture of Schwarz that such configurations are BPS states.

Prospecting for exo-Earths in multiple planet systems with a gas giant

description: In this work, we hunt for the best places to find exo-Earths in the currently known exoplanet population. While it is still unclear whether Jupiter had a beneficial or detrimental effect on the creation of the right environment for a habitable Earth to develop, we focus on the 51 multiple planet systems that have at least one Jupiter-like planet and aim to identify which would be good candidates to host an exo-Earth. We conduct a series of numerical simulations to identify dynamically stable regions of the habitable zone of the multiple exoplanet systems capable of hosting an Earth-mass planet. We produce a candidate list of 16 systems that could host such a stable exo-Earth in their habitable zone, and for which the induced radial velocity signal of a hypothetical one, two or four Earth-mass planet on the host star would be detectable with the ESPRESSO spectrograph. We find that whilst the gravitational interactions with the massive planet nearest the habitable zone are critical in determining stability, the secular resonant interactions between multiple planets can also have a dramatic influence on the overall stability of the habitable zone.

Zodiacal Light Beyond Earth Orbit Observed with Pioneer 10

description: We reanalyze the Imaging Photopolarimeter data from Pioneer 10 to study the zodiacal light in the B and R bands beyond Earth orbit, applying an improved method to subtract integrated star light (ISL) and diffuse Galactic light (DGL). We found that there exists a significant instrumental offset, making it difficult to examine the absolute sky brightness. Instead, we analyzed the differential brightness, i.e., the difference in sky brightness from the average at high ecliptic latitude, and compared with that expected from the model zodiacal light. At a heliocentric distance of r<2 au, we found a fairly good correlation between the J-band model zodiacal light and the residual sky brightness after subtracting the ISL and DGL. The reflectances of the interplanetary dust derived from the correlation study are marginally consistent with previous works. The zodiacal light is not significantly detectable at r>3 au, as previously reported. However, a clear discrepancy from the model is found at r=2.94 au which indicates the existence of a local dust cloud produced by the collision of asteroids or dust trail from active asteroids (or main-belt comets). Our result confirms that the main component of the zodiacal light (smooth cloud) is consistent with the model even beyond the earth orbit, which justifies the detection of the extragalactic background light after subtracting the zodiacal light based on the model.

description: In pathology, histopathology is a discipline of expertise that deals with recognizing minute structural alterations marked by ailments in tissue layers. Most of histopathological techniques simulating those of applied for study the normal histological structures. For the demonstration of minute histological changes, the tissue must be processed in such a manner that it will provide maximum information. Particularly in the veterinary sciences, histological diagnosis is a disregarded field. Many times, it has been observed that the procedures are not properly followed or the qualified person trained for histopathology is not available, which in turn affects the interpretation and /or diagnosis.

description: In this paper, a novel image encryption algorithm, which involves a chaotic block image scrambling followed by a two-dimensional (2-D) discrete linear chirp transform, is proposed. The definition of the 2-D discrete linear chirp transform is introduced and then it is used to construct the basis of the novel encryption algorithm. Finally, security analysis are performed to show the quality of the encryption process using different metrics.
Singularity of the density of states in the two-dimensional Hubbard model from finite size scaling of Yang-Lee zeros

description: A finite size scaling is applied to the Yang-Lee zeros of the grand canonical partition function for the 2-D Hubbard model in the complex chemical potential plane. The logarithmic scaling of the imaginary part of the zeros with the system size indicates a singular dependence of the carrier density on the chemical potential. Our analysis points to a second-order phase transition with critical exponent ${1\over δ}={1\over 2}\pm {1\over 3}$ which leads to a divergence of the electronic susceptibility. We interprete these results as reflecting singular behaviour of the density of states in the quasiparticle spectrum.

Rapidity-Separation Dependence and the Large Next-to-Leading Corrections to the BFKL Equation
Creators: name: Schmidt, Carl R.
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Recent concerns about the very large next-to-leading logarithmic (NLL) corrections to the BFKL equation are addressed by the introduction of a physical rapidity-separation parameter $Δ$. At the leading logarithm (LL) this parameter enforces the constraint that successive emitted gluons have a minimum separation in rapidity, $y_{i+1}-y_i>Δ$. The most significant effect is to reduce the BFKL Pomeron intercept from the standard result as $Δ$ is increased from 0 (standard BFKL). At NLL this $Δ$-dependence is compensated by a modification of the BFKL kernel, such that the total dependence on $Δ$ is formally next-to-next-to-leading logarithmic. In this formulation, as long as $Δ\gtrsim2.2$ (for $α_{s}=0.15$): (i) the NLL BFKL pomeron intercept is stable with respect to variations of $Δ$, and (ii) the NLL correction is small compared to the LL result. Implications for the applicability of the BFKL resummation to phenomenology are considered.

description: Agent based simulation of social organizations, via the investigation of agents' training and learning tactics and strategies, has been inspired by the ability of humans to learn from social environments which are rich in agents, interactions and partial or hidden information. Such richness is a source of complexity that an effective learner has to be able to navigate. This paper focuses on the investigation of the impact of the environmental complexity on the game playing-and-learning behavior of synthetic agents. We demonstrate our approach using two independent turn-based zero-sum games as the basis of forming social events which are characterized both by competition and cooperation. The paper's key highlight is that as the complexity of a social environment changes, an effective player has to adapt its learning and playing profile to maintain a given performance profile

description: We identify necessary and sufficient conditions for a quantum channel to be optimal for any convex optimization problem in which the optimization is taken over the set of all quantum channels of a fixed size. Optimality conditions for convex optimization problems over the set of all quantum measurements of a given system having a fixed number of measurement outcomes are obtained as a special case. In the case of linear objective functions for measurement optimization problems, our conditions reduce to the well-known Holevo-Yuen-Kennedy-Lax measurement optimality conditions. We illustrate how our conditions can be applied to various state transformation problems having non-linear objective functions based on the fidelity, trace distance, and quantum relative entropy.

description: Forecasting the future course of epidemics has always been one of the main goals of epidemic modelling. This chapter reviews statistical methods to quantify the accuracy of epidemic forecasts. We distinguish point and probabilistic forecasts and describe different methods to evaluate and compare the predictive performance across models. Two case studies demonstrate how to apply the different techniques to uni- and multivariate forecasts. We focus on forecasting count time series from routine public health surveillance: weekly counts of influenza-like illness in Switzerland, and age-stratified counts of norovirus gastroenteritis in Berlin, Germany. Data and code for all analyses are available in a supplementary R package.

description: A two-dimensional scandium monochloride sheet was investigated by using density functional theory. It could be exfoliated from a known bulk material with a cleavage energy slightly lower than that of graphene. The sheet has a ferromagnetic ground state with a Curie temperature of 100 K. Moreover, the sheet becomes a half-metal under hole doping. The Curie temperature increases to 250 K with the doping amount of 0.4 per primitive cell, which is close to the ice point. The two-dimensional scandium monochloride sheet should be a good candidate for two-dimensional spintronics.

description:  A fluid structure interaction model of a left anterior descending (LAD) coronary artery was developed, incorporating transient blood flow, cyclic bending motion of the artery, and myocardial contraction. The 3D geometry was constructed based on a patient's computed tomography angiography data. To simulate disease conditions, a plaque was placed within the LAD to create a 70% stenosis. The bending motion of the blood vessel was prescribed based on the LAD spatial information. The pressure induced by myocardial contraction was applied to the outside of the blood vessel wall. The fluid domain was solved using the Navier-Stokes equations. The arterial wall was defined as a nonlinear elastic, anisotropic, and incompressible material, and the mechanical behavior was described using the modified hyper-elastic Mooney-Rivlin model. The fluid (blood) and solid (vascular wall) domains were fully coupled. The simulation results demonstrated that besides vessel bending/stretching motion, myocardial contraction had a significant effect on local hemodynamics and vascular all stress/strain distribution. It not only transiently increased blood flow velocity and fluid wall shear stress, but also changed shear stress patterns. The presence of the plaque significantly reduced vascular wall tensile strain. Compared to the coronary artery models developed previously, the current model had improved physiological relevance.

description: In this work, we present a novel strategy for correcting imperfections in occupancy grid maps called map decay. The objective of map decay is to correct invalid occupancy probabilities of map cells that are unobservable by sensors. The strategy was inspired by an analogy between the memory architecture believed to exist in the human brain and the maps maintained by an autonomous vehicle. It consists in merging sensory information obtained during runtime (online) with a priori data from a high-precision map constructed offline. In map decay, cells observed by sensors are updated using traditional occupancy grid mapping techniques and unobserved cells are adjusted so that their occupancy probabilities tend to the values found in the offline map. This strategy is grounded in the idea that the most precise information available about an unobservable cell is the value found in the high-precision offline map. Map decay was successfully tested and is still in use in the IARA autonomous vehicle from Universidade Federal do Espírito Santo.

title: Digital Storytelling to Protect the Planet: Black and Indigenous Youth Activism as Rising Resistance
Creators: name: Vergette, Charlotte
Publisher: name: University of Kent
Year: 2024

description: The current narrativization of the youth-led climate justice movement perpetuates the racist and colonial roots of mainstream environmentalism in the settler state of the United States of America. This stale story is challenged by the rising resistance of Black and Indigenous youth activists seeking to protect the planet through new and creative means of expression and self-representation. They are bringing a new rhythm to the environmental movement that disturbs the dominant narrative of whiteness and exceptionalism, unearthing excluded and erased histories of contributions to planetary protection from their own communities. The digital storytelling of Black and Indigenous youth strikes at the heart of colonial-capitalist logics and calls attention to the entanglements of environmentalism and white supremacy. Situating these contemporary youth efforts in longer legacies of influence and involvement from Black and Indigenous communities for planetary protection allows for a more expansive view on their environmental contributions, one which highlights Black and Indigenous youth as indispensable leaders in the youth climate justice movement. In forging creative coalitions that are rooted in sonic solidarity, current efforts towards climate justice and co-liberation are being remixed and reoriented towards decolonial futures.

description: We report experimental studies of disorder-induced transitions between quantum-Hall, metallic, and insulating states in a very dilute two-dimensional electron system in silicon at a magnetic field corresponding to Landau level filling factor $ν=1$. At low disorder, the lowest extended state at $ν=1$ is below the Fermi energy so that the system is in the quantum Hall state. Our data show that with increasing disorder (but at constant electron density and magnetic field), the extended state DOES NOT DISAPPEAR BUT FLOATS UP IN ENERGY SO THAT THE SYSTEM BECOMES INSULATING. As the extended state crosses the Fermi energy, the conductivity $σ_{xx}\sim e^2/2h$ has temperature dependence characteristic of a metallic system.

description: Developing sensors with high sensitivity and selectivity for detecting neurotransmitters under near-physiological conditions is a major challenge and is crucial for preventing diseases of the nervous, cardiovascular, and endocrine systems. Most existing systems that meet these requirements involve either complicated synthesis processes, require sulfur groups, or are not functional under aqueous conditions. Herein, we report that the self-organisation of a simple imine ligand L with copper(II) tetrafluoroborate leads to the formation of a [CuL2](BF4)2 complex (CuL2) with a 2 : 1 ligand-to-metal ratio, as confirmed by high-resolution electrospray ionization mass spectrometry (HR ESI-MS), Fourier-transform infrared (FT-IR) spectroscopy and single-crystal X-ray analysis. Surprisingly, modifying a gold surface with a self-assembled monolayer of the CuL2 complex created a stable sensor for selective detection of epinephrine (EP) using differential pulse voltammetry (DPV) in phosphate buffer solution (PBS) at pH 7.0. A linear correlation between the current response and the concentration of EP was observed with a detection limit of 0.03 μM, high reproducibility and good stability in the range of 0.0001 to 0.875 mM. These results show that the new sensor (Cu/Au) can serve as a reliable analytical tool to selectively detect EP alone and in a mixture with coexisting uric acid (UA) in tested samples.

description: We explored the surface enhanced Raman scattering (SERS) activity of the InN nanostructures, possessing surface electron accumulation (SEA), using the Rhodamine 6G (R6G) molecules. SERS enhancement is observed for the InN nanostructures which possess surface electron accumulation (SEA). In case of high temperature grown InN samples, a peak is observed in the low wave number (THz region) of Raman spectra of InN nanostructures originating from excitation of the two dimensional (2D) plasmons of the SEA. The enhancement factor of four orders was calculated with the assumption of monolayer coverage of analyte molecule. SERS enhancement of InN nanostructures is attributed to the 2D plasmonic nature of InN nanostructures invoking SEA, rather than the contributions from 3D surface plasmon resonance (SPR) and chemical interaction. The role of 2D plasmon excitation in SERS enhancement is corroborated by the near-field light-matter interaction studies using near-field scanning optical microscopy.

Congestion fronts of diffusing particles
Creators: name: Burger, Bastian

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study two new models of two particle species invading a surface from opposite sides. Collisions of particles of different species lead to the formation of congestion fronts. One of the models implements a reversible process whereas in the other model the congestion front forms irreversibly. For both models we find that the congestion fronts are self-affine but with different roughness exponents. For low densities the system does not congest and we find a phase transition between a phase of freely moving particles and a congestion phase.

Publisher: name: Zenodo
Year: 2025

description: Natural disasters, including earthquakes, hurricanes, wildfires, and floods, have devastating impacts on human life,infrastructure, and the environment. Effective prediction and response to these events are essential for minimizing damage andensuring public safety. Deep learning, a subset of artificial intelligence (AI), has shown immense potential in improving naturaldisaster prediction, early warning systems, and disaster response planning. This paper explores various deep learning techniques,such as convolutional neural networks (CNNs), recurrent neural networks (RNNs), and generative adversarial networks (GANs),applied to the prediction and mitigation of natural disasters. The paper highlights the use of satellite imagery, sensor data, andmeteorological models in disaster forecasting and emergency management. It also examines the role of deep learning in postdisasterrecovery, from damage assessment to resource allocation. Through case studies and real-world applications, the paperdemonstrates how deep learning is transforming natural disaster prediction and response, contributing to enhanced resilienceand preparedness.

description: Gas sensors at low operating temperature with high sensitivity are the demand for the group III nitrides owing to their high chemical and thermal stability. The CH4 sensing is realized for the Al0.07Ga0.93N nanowires (NWs) with an improved response over the GaN NWs at a low operating temperature of 50 °C, for the first time. Al0.07Ga0.93N NWs were synthesized via ion beam mixing process using inert gas ion irradiation on the bilayer of Al/GaN NWs. The sensing mechanism is explained with the help of native defects present in the system. The number of shallow acceptors created by Ga vacancy (V_Ga) is found to be higher in Al0.07Ga0.93N NWs than those in the as-grown GaN NWs. The role of O antisite defect (ON) for the formation of shallow V_Ga is inferred from photoluminescence spectroscopic analysis. These native defects strongly influence the gas sensing behaviour resulting in the enhanced and low temperature CH4 sensing.

Models of Neutrino Masses from Oscillations with Maximal Mixing
Creators: name: Altarelli, Guido

Publisher: name: arXiv
Year: 1998
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We discuss models of neutrino masses that lead to a large mixing angle for atmospheric neutrino oscillations. In particular we study a mechanism where a simple texture for the Dirac matrix leads to the observed pattern of mixings for a continuous range of Majorana matrices in a reasonably natural way. Both nearly maximal and small mixing solutions for solar neutrinos are compatible with this model. Possible dynamical realizations are discussed and a detailed example in terms of horizontal U(1) charges is presented.

description: Alzheimer’s disease is linked with diabetes and cancer, emphasising the need for effective treatments. Plantago lanceolata, recognised as safe by various pharmacopeias, was investigated in this study for therapeutic potential. We examined the effects of its leaf extracts and sub-extracts (methanol, hexane, dichloromethane, ethyl acetate, butanol, aqueous) on AChE, BChE, α-amylase, α-glucosidase enzymes, as well as their impact on HDF-a and U87-MG cancer cells. The phytochemical characterisation was performed using ICP-MS and LC–MS/MS. Cytotoxic effects were evaluated on HDF-a and U87-MG cell lines, along with assessments for nuclear abnormalities. Na and K were detected in extracts, with isoleucine and cyanidin-3-O-glucoside being the most concentrated compounds. Extracts at concentrations exceeding 25 µg/mL significantly increased cytotoxicity in HDF-a cell lines compared to the control group, without inducing nuclear abnormalities. Methanol extract demonstrated moderate inhibition against AChE and BChE at concentrations of 100 µg/mL and 500 µg/mL, respectively. These findings suggest that extracts exhibit potential therapeutic effects.
The Shape of Branes Pulled by Strings
Creators: name: Hashimoto, Akikazu
Publisher: name: arXiv
Year: 1997
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We examine the system where a string stretches between pair of D-branes, and study the bending of the D-brane caused by the tension of the string. If the distance between the pair of D-branes is sent to infinity, the tension of the string stretching between them is strong enough to pull the spike all the way to infinity. We study the shape of these spikes when the branes are finite distance apart using two different methods. First, we consider a string stretched between a pair of D2-branes in type IIA theory by going to the M-theory limit in which all of these branes are M-theory 2-branes embedded along a holomorphic curve. Second, we consider a D-string stretched between a pair of D3-branes in type IIB theory and infer the geometry of the D3-brane embeddings from the configuration of the adjoint scalar field in the magnetic monopole solution of Prasad and Sommerfield. The case of fundamental string stretching between a pair of D3-branes follows from S-duality. The energy of these configurations matches the expected value based on fundamental string and D-string tensions.

description: We investigate quantum phase transitions in $XY$ spin models using Dzyaloshinsky-Moriya (DM) interactions. We identify the quantum critical points via quantum Fisher information and quantum coherence, finding that higher DM couplings suppress quantum phase transitions. However, quantum coherence (characterized by the $l_1$-norm and relative entropy) decreases as the DM coupling increases. Herein, we present both analytical and numerical results.

Spectral Statistics Beyond Random Matrix Theory

description: Using a nonperturbative approach we examine the large frequency asymptotics of the two-point level density correlator in weakly disordered metallic grains. This allows us to study the behavior of the two-level structure factor close to the Heisenberg time. We find that the singularities (present for random matrix ensembles) are washed out in a grain with a finite conductance. The results are nonuniversal (they depend on the shape of the grain and on its conductance), though they suggest a generalization for any system with finite Heisenberg time.

Measurements of Cross Sections and Forward-Backward Asymmetries at the Z Resonance and Determination of Electroweak Parameters
Creators: name: L3 Collaboration
Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: We report on measurements of hadronic and leptonic cross sections and leptonic forward-backward asymmetries performed with the L3 detector in the years 1993-95. A total luminosity of 103 pb^-1 was collected at centre-of-mass energies \sqrt{s} ~ m_Z and \sqrt{s} ~ m_Z +/- 1.8 GeV which corresponds to 2.5 million hadronic and 245 thousand leptonic events selected. These data lead to a significantly improved determination of Z parameters. From the total cross sections, combined with our measurements in 1990-92, we obtain the final results: m_Z = 91189.8 +/- 3.1 MeV, Gamma_Z = 2502.4 +/- 4.2 MeV, Gamma_had = 1741.1 +/- 3.8 MeV, Gamma_l = 84.14 +/- 0.17 MeV. An invisible width of Gamma_inv = 499.1 +/- 2.9 MeV is derived which in the Standard Model yields for the number of light neutrino species N_nu = 2.978 +/- 0.014. Adding our results on the leptonic forward-backward asymmetries and the tau polarisation, the effective vector and axial-vector coupling constants of the neutral weak current to charged leptons are determined to be \bar{g}_V^l = -0.0397 +/- 0.0017 and \bar{g}_A^l = -0.50153 +/- 0.00053.Including our measurements of the Z -> b \bar{b} forward-backward and quark charge asymmetries a value for the effective electroweak mixing angle of sin^2\barθ_W = 0.23093 +/- 0.00066 is derived. All these measurements are in good agreement with the Standard Model of electroweak interactions. Using all our measurements of electroweak observables an upper limit on the mass of the Standard Model Higgs boson of m_H < 133 GeV is set at 95% confidence level.

Local cosmic strings from Pseudo-anomalous U(1)
Creators: name: Deffayet, C.

Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Local cosmic strings solutions are introduced in a model with a pseudo-anomalous U(1) gauge symmetry. Such a symmetry is present in many superstring compactification models. The coupling of those strings with the axion necessary in order to cancel the anomalies does not prevent them from being local, even though their energy per unit length is found to diverge logarithmically. We discuss briefly the formation of such strings and the phenomenological constraints that apply to their parameters.
