description: Primordial Black Holes could be an important component of the dark matter in the Universe. If they exist, they would add a Poisson component to the matter power spectrum. The extra power would speed up the emergence of dark matter halos that seed the formation of first stars and galaxies. Kashlinsky (2021) suggested that the additional velocity fluctuations would accelerate the infall of baryons onto the dark matter potential wells. We analyze the effect of Primordial Black Holes on the baryon infall from recombination to reionization and find the correction to be a few percent of the power suppression first identified by Tseliakhovich \& Hirata (2010). However, the dynamical effect of this correction in addition to the extra power speeds up the formation of halos in the mass range of $10^4-10^{5-6}$M$_\odot$, while slightly decreasing the formation of those in the range $10^6-10^8$M$_\odot$ confirming earlier analytic estimates and recent results of numerical simulations.

description: The Early Universe, together with many nearby dwarf galaxies, is deficient in heavy elements. The evolution of massive stars in such environments is thought to be affected by rotation. Extreme rotators amongst them tend to form decretion disks and manifest themselves as OBe stars. We use a combination of U B, GAIA, Spitzer, and Hubble Space Telescope photometry to identify the complete populations of massive OBe stars - one hundred to thousands in number - in five nearby dwarf galaxies. This allows us to derive the galaxy-wide fractions of main sequence stars that are OBe stars (f_OBe), and how it depends on absolute magnitude, mass, and metallicity (Z). We find f_OBe = 0.22 in the Large Magellanic Cloud (0.5 Z_Sun), increasing to f_OBe = 0.31 in the Small Magellanic Cloud (0.2 Z_Sun). In the so far unexplored metallicity regime below 0.2 Z_Sun, in Holmberg I, Holmberg II, and Sextans A, we also obtain high OBe star fractions of 0.27, 0.27, and 0.27, respectively. These high OBe star fractions, and the strong contribution in the stellar mass range which dominates the production of supernovae, shed new light on the formation channel of OBe stars, as well as on the preference of long-duration gamma-ray bursts and superluminous supernovae to occur in metal-poor galaxies.

description: Natural fibres are used as reinforcement in friction composites to replace asbestos due to the health hazards caused by asbestos fibres which may cause asbestosis, mesothelioma, and lung cancer. Natural fibres such as corn, palm and sugar bars gave relatively high friction coefficient suitable for friction materials. It is necessary to investigate the variation of friction coefficient with temperature. The present work discusses the fade of composites reinforced by corn, palm and sugar bar fibres. Experiments were carried out to determine friction coefficient and temperature rise for the tested composites. The results of the tested composites were compared to that observed from three types of conventional friction brake linings. The experimental results show that composites containing 25 % palm fibres and 10 % iron powder gave the minimum fade among the conventional brake linings, while friction composites containing sugar bare fibres displayed the highest fade. Besides, addition of aluminium and copper into the matrix of the composites displayed relatively lower fade value due to their high thermal conductivity.

description: To formulate gravity in spacetimes bounded by a null boundary, an arbitrary hypothetical null surface, boundary degrees of freedom (d.o.f) should be added to account for the d.o.f and dynamics in the spacetime regions excised behind the null boundary. In the D dimensional example, boundary d.o.f are labelled by D charges defined at D-2 dimensional spacelike slices at the null boundary. While boundary modes can have their own boundary dynamics, their interaction with the bulk modes is governed by flux-balance equations which may be interpreted as a diffusion equation describing "dissolution" of bulk gravitons into the boundary. From boundary viewpoint, boundary d.o.f obey local thermodynamical equations at the boundary. Our description suggests a new "semiclassical" quantization of the system in which boundary d.o.f are quantized while bulk is classical. This semiclassical treatment may be relevant to questions in black hole physics.

Quantum Gate Generation in Two-Level Open Quantum Systems by Coherent and Incoherent Photons Found with Gradient Search

description: In this work, we consider an environment formed by incoherent photons as a resource for controlling open quantum systems via an incoherent control. We exploit a coherent control in the Hamiltonian and an incoherent control in the dissipator which induces the time-dependent decoherence rates $γ_k(t)$ (via time-dependent spectral density of incoherent photons) for generation of single-qubit gates for a two-level open quantum system which evolves according to the Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) master equation with time-dependent coefficients determined by these coherent and incoherent controls. The control problem is formulated as minimization of the objective functional, which is the sum of Hilbert-Schmidt norms between four fixed basis states evolved under the GKSL master equation with controls and the same four states evolved under the ideal gate transformation. The exact expression for the gradient of the objective functional with respect to piecewise constant controls is obtained. Subsequent optimization is performed using a gradient type algorithm with an adaptive step size that leads to oscillating behaviour of the gradient norm vs iterations. Optimal trajectories in the Bloch ball for various initial states are computed. A relation of quantum gate generation with optimization on complex Stiefel manifolds is discussed. We develop methodology and apply it here for unitary gates as a testing example. The next step is to apply the method for generation of non-unitary processes and to multi-level quantum systems.

description: Solid modeling is a technique underlying CAD software as we see it today, and its theories and algorithms are among the most fundamental milestones in the historical development of CAD. Basically, it has answered the question of what geometric information a computer should store and how to store/manipulate them in order for the computer to aid the processes of design and manufacturing. This paper provides a brief review (in Chinese) on the historical development of solid modeling, its fundamental research problems, as well as their challenges and state of the art. It then concludes with three prospective trends of solid modeling, especially the promising paradigm shift from "Computer-Aided Design" to "Computer-Automated Design".

Large Chern Number and Edge Currents in Sr2RuO4

description: We show from a weak coupling microscopic calculation that the most favored chiral superconducting order parameter in Sr2RuO4 has Chern number |C|=7. The two dominant components of this order parameter are given by sin(3 kx) + i sin(3 ky) and sin(kx) cos(ky) + i sin(ky) cos(kx) and lie in the same irreducible representation Eu of the tetragonal point group as the usually assumed gap function sin(kx) + i sin(ky). While the latter gap function leads to C=1, the two former lead to C=-7, which is also allowed for an Eu gap function since the tetragonal symmetry only fixes C modulo 4. Since it was shown that the edge currents of a |C|>1 superconductor vanish exactly in the continuum limit, and can be strongly reduced on the lattice, this form of order parameter could help resolve the conflict between experimental observation of time-reversal symmetry breaking and yet the absence of observed edge currents in Sr2RuO4.

description: Abstract
This issue has been recognized as a significant problem since the 1980s. While manual cleaning was initially considered a potential solution, it has become evident that these regions necessitate automated cleaning systems. A comprehensive review and discussion on the impact of dust on PV glass, and the effect of dust particle physical and chemical properties, strategies for dust moderation and cleaning, approaches used to model dust effect, and emerging prospects in the field are presented. By examining these aspects, this study contributes to an enhanced understanding of the challenges associated with dust accumulation on PV and provides insights into potential solutions for optimized performance and stability.

description: We describe an apparatus designed to make non-demolition measurements on a Bose-Einstein condensate (BEC) trapped in a double-well optical cavity. This apparatus contains, as well as the bosonic gas and the trap, an optical cavity. We show how the interaction between the light and the atoms, under appropriate conditions, can allow for a weakly disturbing yet highly precise measurement of the population imbalance between the two wells and its variance. We show that the setting is well suited for the implementation of quantum-limited estimation strategies for the inference of the key parameters defining the evolution of the atomic system and based on measurements performed on the cavity field. This would enable {\it de facto} Hamiltonian diagnosis via a highly controllable quantum probe.

description: Since 2005 ESO has been working with its community and industry to develop an extremely large optical/infrared telescope. ESO's Extremely Large Telescope, or ELT for short, is a revolutionary ground-based telescope that will have a 39-metre main mirror and will be the largest visible and infrared light telescope in the world. To address specific topics that are needed for the science operations and calibrations of the telescope, thirteen specific working groups were created to coordinate the effort between ESO, the instrument consortia, and the wider community. We describe here the goals of these working groups as well as their achievements so far.

description: We study the transport properties of a single photon scattered by a two-level system (TLS) in a T-shaped waveguide, which is made of two coupled-resonator waveguides (CRWs)--- an infinite CRW and a semi-infinite CRW. The spontaneous emission of the TLS directs single photons from one CRW to the other. Although the transfer rate is different for the wave incident from different CRWs, due to the boundary breaking the translational symmetry, the boundary can enhance the transfer rate found in Phys. Rev. Lett. 111, 103604 (2013) and Phys. Rev. A 89, 013805 (2014), as the transfer rate could be unity for the wave incident from the semi-infinite CRW.

description: The centers of our cities remain, despite nearly a century of suburbanization, the symbolic and actual centers of our civilization. Like the heart of a body, they cannot be examined in isolation, for clogging of an artery can cause death as easily as a direct stab at the heart. It is with this broader public discussion in mind that this thesis on downtown revitalization is written. While it is an examination of the ongoing process of downtown redevelopment in Austin, it does not attempt to avoid grappling with broader questions regarding the direction of our society. It should be seen as a contribution to the growing body of citizen and government literature on Austin's development. It is intended to do this on several levels: (1) By offering some history and analysis of the motives and interests involved in the process of development; and (2) by attempting to articulate a set of goals and strategies somewhat different from those of recent planning documents for the area. To some readers, these goals and strategies may appear radical at cursory reading. They are, however, presented in light of the very real constraints imposed by our economic system, yet with frank discussion of how these constraints must be altered in the interest of both democracy and rational development. Finally, it should be noted that the ideas in this study are not all original. This study was not conducted simply to present yet another glorious plan for the downtown. Rather, it is hoped that it will contribute to the reconciliation of differences between various groups and individuals regarding downtown. Hopefully it will therefore aid in the process of consensus building amongst groups previously marginal to the planning process which affects them all. This consensus building is prerequisite to the development of an alternative program of revitalization to those of the immediate past

description: We present the first empirical constraints on the turbulent velocity field of the diffuse circumgalactic medium around four luminous QSOs at $z\!\approx\!0.5$--1.1. Spatially extended nebulae of $\approx\!50$--100 physical kpc in diameter centered on the QSOs are revealed in [OII]$λλ\,3727,3729$ and/or [OIII]$λ\,5008$ emission lines in integral field spectroscopic observations obtained using MUSE on the VLT. We measure the second- and third-order velocity structure functions (VSFs) over a range of scales, from $\lesssim\!5$ kpc to $\approx\!20$--50 kpc, to quantify the turbulent energy transfer between different scales in these nebulae. While no constraints on the energy injection and dissipation scales can be obtained from the current data, we show that robust constraints on the power-law slope of the VSFs can be determined after accounting for the effects of atmospheric seeing, spatial smoothing, and large-scale bulk flows. Out of the four QSO nebulae studied, one exhibits VSFs in spectacular agreement with the Kolmogorov law, expected for isotropic, homogeneous, and incompressible turbulent flows. The other three fields exhibit a shallower decline in the VSFs from large to small scales. However, with a limited dynamic range in the spatial scales in seeing-limited data, no constraints can be obtained for the VSF slopes of these three nebulae. For the QSO nebula consistent with the Kolmogorov law, we determine a turbulence energy cascade rate of $\approx\!0.2$ cm$^{2}$ s$^{-3}$. We discuss the implication of the observed VSFs in the context of QSO feeding and feedback in the circumgalactic medium.

description: For a three dimensional system we answer two questions, how simple a particle system might be to show the quasicrystal order and, what system features are the most important for quasicrystal formation? One-component system of particles with isotropic pair interaction is one of the simplest ones. We show that such system may be driven to three-dimensional decagonal (10-fold) quasicrystalline state just by purely repulsive, isotropic and monotonic interaction pair potential with two characteristic length scales; no attraction is needed. The second question we answer defining universal (nearly independent from the shape of the pair potential) effective integral parameters related to the first peak of the radial distribution function. The universality is illustrated by demonstrating the quasicrystalline order for a number of particle systems with absolutely different interaction potentials, both purely repulsive and attractive, but with the same effective integral parameters. Simple models like we study qualitatively describe effective interaction in molecular liquids, soft matter systems and metallic alloys for which quasicrystals have been experimentally observed.

description: The detection of habitable worlds is one of humanity's greatest endeavors. So far, astrobiological studies show that one of the most critical components for life development is liquid water. Its chemical properties and its capacity to dissolve and hence transport other substances makes this constituent a key piece in the development of life. As a consequence, looking for life as we know it is directly related to the search for liquid water. For a remote detection of life in distant planetary systems, this means looking for planets in the so-called habitable zone. In this sense, K-dwarf stars are the perfect hosts. Contrary to G-dwarfs, the habitable zone is closer, thus making planet detection easier using transit or radial velocity techniques. Contrary to M-dwarfs, the stellar activity is much smaller, hence having a smaller impact in both the detectability and in the true habitability of the planet. Also, K-dwarfs are the quietest in terms of oscillations, and granulation noise. Despite this, there is a dearth of planets in the habitable zone of K-dwarfs due to a lack of observing programs devoted to this parameter space. In response to a call for Legacy Programs of the Calar Alto observatory, we have started the first dedicated and systematic search for habitable planets around K-dwarfs, the K-dwarfs Orbited By habitable Exoplanets (KOBE). This survey is monitoring the radial velocity of 50 carefully pre-selected K-dwarfs with the CARMENES instrument along 5 semesters with an average of 90 data points per target. Based on planet occurrence rates convolved with our detectability limits, we expect to find $1.68\pm 0.25$ planets per star in the KOBE sample and in half of the sample we expect to find one of those planets within the habitable zone. In this paper, we describe the project motivation, goals and target selection and preliminary stellar characterization.

description: Mitochondrial dysfunction has been reported in obesity and insulin resistance, but primary genetic mitochondrial dysfunction is generally not associated with these, arguing against a straightforward causal relationship. A rare exception, recently identified in humans, is a syndrome of lower body adipose loss, leptin-deficient severe upper body adipose overgrowth, and insulin resistance caused by the p.Arg707Trp mutation in MFN2, encoding mitofusin 2. How the resulting selective form of mitochondrial dysfunction leads to tissue- and adipose depot-specific growth abnormalities and systemic biochemical perturbation is unknown. To address this, Mfn2R707W/R707W knock-in mice were generated and phenotyped on chow and high fat diets. Electron microscopy revealed adipose-specific mitochondrial morphological abnormalities. Oxidative phosphorylation measured in isolated mitochondria was unperturbed, but the cellular integrated stress response was activated in adipose tissue. Fat mass and distribution, body weight, and systemic glucose and lipid metabolism were unchanged, however serum leptin and adiponectin concentrations, and their secretion from adipose explants were reduced. Pharmacological induction of the integrated stress response in wild-type adipocytes also reduced secretion of leptin and adiponectin, suggesting an explanation for the in vivo findings. These data suggest that the p.Arg707Trp MFN2 mutation selectively perturbs mitochondrial morphology and activates the integrated stress response in adipose tissue. In mice, this does not disrupt most adipocyte functions or systemic metabolism, whereas in humans it is associated with pathological adipose remodelling and metabolic disease. In both species, disproportionate effects on leptin secretion may relate to cell autonomous induction of the integrated stress response.

description: In this work we evaluate the $^1S_0$ superfluidity of $Λ$ hyperons in $β$-stable strange hadronic matter. We investigate the equation of state (EOS) of hadronic matter at finite values of baryon density and temperature in the relativistic mean field (RMF) theory. Effects of the introduced isoscalar-isovector cross-interaction term on the $Λ$ superfluidity are investigated systematically. In addition, the temperature effects on the superfluidity of $Λ$ hyperons in hadronic matter are discussed. It is found that the density region and the magnitude of the $Λ$ pairing gap are dependent on the cross-interaction term. The obtained maximal critical temperature of $Λ$ superfluid is around $10^9$ K.

description: The paper titled "Critical Thinking" provides an overview of the importance of critical thinking skills in various aspects of life, particularly in the context of globalization in Cambodia. It emphasizes the need for individuals to develop the ability to evaluate evidence, identify assumptions, draw conclusions, and solve problems. The document also highlights the role of critical thinking in protecting culture and identity from the negative impacts of globalization.
The course concepts of critical thinking are discussed, including evaluating evidence, identifying assumptions, drawing conclusions, recognizing fallacies, and fostering creativity. The paper emphasizes that critical thinking is a skill that can be taught and learned through problem-based learning, workshops, and exercises. However, it acknowledges the challenges in teaching critical thinking in Cambodia due to the traditional education system's lack of focus on this skill and the limited training of teachers.
The paper further explores the benefits of developing critical thinking abilities, such as improved decision-making, increased creativity, greater resilience, enhanced problem-solving skills, and improved communication skills. It provides tips for evaluating evidence, identifying assumptions, and drawing conclusions. Additionally, it discusses common mistakes to avoid when drawing conclusions, such as ignoring contradictory evidence and allowing biases to influence decision-making.
The paper concludes by expressing optimism about the future of critical thinking in Cambodia, highlighting the growing awareness of its importance and ongoing initiatives to promote critical thinking education. It encourages individuals to support these initiatives, encourage children and students to develop critical thinking skills, and serve as role models themselves. The ultimate goal is to ensure a bright and prosperous future for Cambodia through a well-informed and engaged citizenry capable of making wise decisions.
Overall, the document provides a comprehensive overview of critical thinking, its relevance in Cambodia's context, and practical guidance for developing and applying critical thinking skills in various aspects of life.

description: We investigate unitarity within the Complex-Mass Scheme, a convenient universal scheme for perturbative calculations involving unstable particles in Quantum Field Theory which guarantees exact gauge invariance. Since this scheme requires to introduce complex masses and complex couplings, the Cutkosky cutting rules, which express perturbative unitarity in theories of stable particles, are no longer valid. We derive corresponding rules for scalar theories with unstable particles based on Veltman's Largest-Time Equation and prove unitarity in this framework.

description: In the paper a theoretical study the both the quantized energies of excitonic states and their wave functions in gapped graphene and in monolayer of MoS2 is presented. An integral two-dimensional Schrödinger equation of the electron-hole pairing for a particles with electron-hole symmetry of reflection is analytically solved. The solutions of Schrödinger equation in momentum space in gapped graphene and in the direct band monolayer of MoS2 by projection the two-dimensional space of momentum on the three-dimensional sphere are found. We analytically solve an integral two-dimensional Schrödinger equation of the electron-hole pairing for particles with electron-hole symmetry of reflection and with strong spin-orbit coupling. In monolayer of MoS2 as well as in single-layer graphene (SLG) the electron-hole pairing leads to the exciton insulator states. Calculating an integral two-dimensional Schrödinger equation of the electron-hole pairing for bilayer graphene, an exciton insulator states with a gap 3 meV are predicted. The particle-hole symmetry of Dirac equation of layered materials allows perfect pairing between electron Fermi sphere and hole Fermi sphere in the valence band and conduction band and hence driving the Cooper instability.

On the co-orbital asteroids in the solar system: medium-term timescale analysis of the quasi-coplanar objects

description: The focus of this work is the current distribution of asteroids in co-orbital motion with Venus, Earth and Jupiter, under a quasi-coplanar configuration and for a medium-term timescale of the order of 900 years. A co-orbital trajectory is a heliocentric orbit trapped in a 1:1 mean-motion resonance with a given planet. As such, to model it this work considers the Restricted Three-Body Problem in the circular-planar case with the help of averaging techniques. The domain of each co-orbital regime, that is, the quasi-satellite motion, the horseshoe motion and the tadpole motion, can be neatly defined by means of an integrable model and a simple bi-dimensional map, that is invariant with respect to the mass parameter of the planet, and turns out to be a remarkable tool to investigate the distribution of the co-orbitals objects of interest. The study is based on the data corresponding to the ephemerides computed by the JPL Horizons system for asteroids with a sufficient low orbital inclination with respect to the Sun-planet orbital plane. These objects are cataloged according to their current dynamics, together with the transitions that occur in the given time frame from a given type of co-orbital motion to another. The results provide a general catalog of co-orbital asteroids in the solar system, the first one to our knowledge, and an efficient mean to study transitions.

description: INTRODUCTION: Rapid evaluations can offer evidence on innovations in health and social care that can be used to inform fast-moving policy and practise, and support their scale-up according to previous research. However, there are few comprehensive accounts of how to plan and conduct large-scale rapid evaluations, ensure scientific rigour, and achieve stakeholder engagement within compressed timeframes. METHODS: Using a case study of a national mixed-methods rapid evaluation of COVID-19 remote home monitoring services in England, conducted during the COVID-19 pandemic, this manuscript examines the process of conducting a large-scale rapid evaluation from design to dissemination and impact, and reflects on the key lessons for conducting future large-scale rapid evaluations. In this manuscript, we describe each stage of the rapid evaluation: convening the team (study team and external collaborators), design and planning (scoping, designing protocols, study set up), data collection and analysis, and dissemination. RESULTS: We reflect on why certain decisions were made and highlight facilitators and challenges. The manuscript concludes with 12 key lessons for conducting large-scale mixed-methods rapid evaluations of healthcare services. We propose that rapid study teams need to: (1) find ways of quickly building trust with external stakeholders, including evidence-users; (2) consider the needs of the rapid evaluation and resources needed; (3) use scoping to ensure the study is highly focused; (4) carefully consider what cannot be completed within a designated timeframe; (5) use structured processes to ensure consistency and rigour; (6) be flexible and responsive to changing needs and circumstances; (7) consider the risks associated with new data collection approaches of quantitative data (and their usability); (8) consider whether it is possible to use aggregated quantitative data, and what that would mean when presenting results, (9) consider using structured processes & layered analysis approaches to rapidly synthesise qualitative findings, (10) consider the balance between speed and the size and skills of the team, (11) ensure all team members know roles and responsibilities and can communicate quickly and clearly; and (12) consider how best to share findings, in discussion with evidence-users, for rapid understanding and use. CONCLUSION: These 12 lessons can be used to inform the development and conduct of future rapid evaluations in a range of contexts and settings.
Statistical physics methods provide the exact solution to a long-standing problem of genetics

description: Analytic and computational methods developed within statistical physics have found applications in numerous disciplines. In this letter, we use such methods to solve a long-standing problem in statistical genetics. The problem, posed by Haldane and Waddington [J.B.S. Haldane and C.H. Waddington, Genetics 16, 357-374 (1931)], concerns so-called recombinant inbred lines (RILs) produced by repeated inbreeding. Haldane and Waddington derived the probabilities of RILs when considering 2 and 3 genes but the case of 4 or more genes has remained elusive. Our solution uses two probabilistic frameworks relatively unknown outside of physics: Glauber's formula and self-consistent equations of the Schwinger-Dyson type. Surprisingly, this combination of statistical formalisms unveils the exact probabilities of RILs for any number of genes. Extensions of the framework may have applications in population genetics and beyond.

Path Integral representation for Polymer Quantized Scalar Fields

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: According to loop quantum gravity, matter fields must be quantized in a background independent manner. For scalar fields, such a background independent quantization is called polymer quantization and is inequivalent to the standard Schrodinger quantization. It is therefore important to obtain predictions from the polymer quantized scalar field theory and compare with the standard results. As a step towards this, we develop a path integral representation for the polymer quantized scalar field. We notice several crucial differences from the path integral for the schrodinger quantized scalar field. One important difference is the appearance of an extra summation at each point in the path integral for the polymer quantized theory. A second crucial difference is the loss of manifest Lorentz symmetry for a polymer quantized theory on Minkowski Space.
description: In this version, the derivation of the path integral is presented starting from the position basis instead of the momentum basis to better highlight the similarities with particle on a circle
