description: This paper uses frame techniques to characterize the Schatten class properties of integral operators. The main result shows that if the coefficients of certain frame expansions of the kernel of an integral operator are in (\ell^{2,p}), then the operator is Schatten p-class. As a corollary, we conclude that if the kernel or Kohn-Nirenberg symbol of a pseudodifferential operator lies in a particular mixed modulation space, then the operator is Schatten p-class. Our corollary improves existing Schatten class results for pseudodifferential operators and the corollary is sharp in the sense that larger mixed modulation spaces yield operators that are not Schatten class.

description: The synthesis of two-dimensional van der Waals magnets has paved the way for both technological applications and fundamental research on magnetism confined to ultra-small length scales. Edge magnetic moments in ferromagnets are expected to be less magnetized than in the sample interior because of the reduced amount of neighboring ferromagnetic spins at the sample edge. We recently demonstrated that CrGeTe3 (CGT) flakes thinner than 10 nm are hard ferromagnets; i.e., they exhibit an open hysteresis loop. In contrast, thicker flakes exhibit zero net remnant field in the interior, with hard ferromagnetism present only at the cleaved edges. This experimental observation suggests that a nontrivial interaction exists between the sample edge and the interior. Here, we demonstrate that artificial edges fabricated by focus ion beam etching also display hard ferromagnetism. This enables us to write magnetic nanowires in CGT directly and use this method to characterize the magnetic interaction between the interior and edge. The results indicate that the interior saturation and depolarization fields depend on the lateral dimensions of the sample. Most notably, the interior region between the edges of a sample narrower than 300 nm becomes a hard ferromagnet, suggesting an enhancement of the magnetic exchange induced by the proximity of the edges. Last, we find that the CGT regions amorphized by the gallium beam are nonmagnetic, which introduces a novel method to tune the local magnetic properties of CGT films, potentially enabling integration into spintronic devices.

description: In this paper we generalize N-fold integer programs and two-stage integer programs with N scenarios to N-fold 4-block decomposable integer programs. We show that for fixed blocks but variable N, these integer programs are polynomial-time solvable for any linear objective. Moreover, we present a polynomial-time computable optimality certificate for the case of fixed blocks, variable N and any convex separable objective function. We conclude with two sample applications, stochastic integer programs with second-order dominance constraints and stochastic integer multi-commodity flows, which (for fixed blocks) can be solved in polynomial time in the number of scenarios and commodities and in the binary encoding length of the input data. In the proof of our main theorem we combine several non-trivial constructions from the theory of Graver bases. We are confident that our approach paves the way for further extensions.

description: Regardless of their prevalence and considerable expansion since the 1980s, evidence concerning the impact of welfare conditionality and marketisation in active labour market policies (ALMPs) has been inconclusive and mostly limited to developed and transition economies. Using mixed methods for collecting and analysing data, this study investigates the deployment of these two policy instruments in the latest addition to the stock of ALMPs: the Kartu Prakerja Program of Indonesia. Our findings indicate positive effects derived from such incorporation of the two instruments in this new program. Specifically, we observed a high level of jobseekers’ engagement and employment outcomes. The program also shaped the development of a provider market that is of higher standard of professionalism. It, however, is not exempt from problems that seem to be of perennial nature in other welfare‐to‐work programs, pointing to the need for greater service tailoring and provider engagement. Impressively, the program represents an example of a genuine policy learning in both policy formulation and re‐formulation during the time of crisis, given that it has been run successfully, along with various adaptions quickly made in response to changing circumstances.
Friction factor characteristics for flow regime transition in concentric annuli
Creators: name: Foster, Allan Wilson
Publisher: name: University of British Columbia
Year: 2011

description: Friction factors have been determined experimentally for flow of water and various aqueous solutions of polyethylene glycol in four different concentric annuli. The annuli studied covered a diameter ratio range of 0.0406 to 0.6331. The annular entrance was sharp-edged and no spacers were used within the system. The Reynolds number range investigated was approximately 200 to 26,000, based on equivalent diameter equal to four times the hydraulic radius. The fully developed friction factors for all four diameter ratios were correlated by the Nikuradse equation for a smooth pipe when the Reynolds number exceeded 3500 and by the Knudsen and Kata theory for laminar flow when the Reynolds number was less than 2200. Deviations from the theory of Hanks for laminar - turbulent transition in the well-developed flow region of concentric annuli could be tentatively accounted for by the extra turbulence arising from the sharp-edged entrance in the present investigation. For well-developed flow the critical Reynolds numbers for the various diameter ratios ranged between 2650 and 3700, and the mode of transition was sharp. However, for low, intermediate and high values of entrance length, respectively, three different modes of transition were found to exist in the annuli studied. Local friction factors were based on pressure gradient, uncorrected for changes in kinetic energy due to the developing velocity profile.

description: Given some group $G$ of logical gates, for instance the Clifford group, what are the quantum encodings for which these logical gates can be implemented by simple physical operations, described by some physical representation of $G$? We study this question by constructing a general form of such encoding maps. For instance, we recover that the $[[5,1,3]]$ and Steane codes admit transversal implementations of the binary tetrahedral and binary octahedral groups, respectively. For bosonic encodings, we show how to obtain the GKP and cat qudit encodings by considering the appropriate groups, and essentially the simplest physical implementations. We further illustrate this approach by introducing a 2-mode bosonic code defined from a constellation of 48 coherent states, for which all single-qubit Clifford gates correspond to passive Gaussian unitaries.

description: We show that the PAMELA anomaly in the positron fraction as well as the ATIC/PPB-BETS excesses in the e^- + e^+ flux are simultaneously explained in our scenario that a hidden U(1)H gauge boson constitutes dark matter of the Universe and decays into the standard-model particles through a kinetic mixing with an U(1)B-L gauge boson. Interestingly, the B-L charge assignment suppresses an antiproton flux in consistent with the PAMELA and BESS experiments, while the hierarchy between the B-L symmetry breaking scale and the weak scale naturally leads to the right lifetime of O(10^26) seconds.

Functional and variables selection in extreme value models for regional flood frequency analysis

Subjects: subject: Methodology (stat.ME)

description: The problem of estimating return levels of river discharge, relevant in flood frequency analysis, is tackled by relying on the extreme value theory. The Generalized Extreme Value (GEV) distribution is assumed to model annual maxima values of river discharge registered at multiple gauging stations belonging to the same river basin. The specific features of the data from the Upper Danube basin drive the definition of the proposed statistical model. Firstly, Bayesian P-splines are considered to account for the non-linear effects of station-specific covariates on the GEV parameters. Secondly, the problem of functional and variable selection is addressed by imposing a grouped horseshoe prior on the coefficients, to encourage the shrinkage of non-relevant components to zero. A cross-validation study is organized to compare the proposed modeling solution to other models, showing its potential in reducing the uncertainty of the ungauged predictions without affecting their calibration.

description: Table S1 shows the distribution of four common respiratory bacteria detected by PCR in the nasopharyngeal swab from children who had definite bacterial pneumonia or presumed viral pneumonia or other pneumonia. This table informs readers if the bacteria in upper respiratory tract, nasopharynx, varies in pneumonia cases who had detectable bacteria in sterile body fluids such as blood and/or pleural fluid compared to those who did not have detectable bacteria in sterile body fluids but had detectable respiratory viruses in nasopharynx and to those who did not have either. Table S2 shows the distribution three blood biomarkers, CRP, WCC and ANC, among definite bacterial pneumonia cases who had empyema, bacteraemia and both empyema and bacteraemia. We found that definite bacterial cases had increased level of blood biomarkers than presumed viral pneumonia or other pneumonia cases (Table 2). We further analysed within the definite bacterial case group to see if these blood biomarkers varies among complicated pneumonia cases (empyema), cases who had bacteraemia (presence of bacteria in blood) and cases who had both empyema and bacteraemia. Table S3 shows the different diagnostic values such as sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for different cut-off values of CRP level to differentiate definite bacterial pneumonia from presumed viral and from presumed viral plus other pneumonias. CRP was found to have capacity to distinguish definite bacterial pneumonia from presumed viral and other pneumonia. While we found CRP level â Ľ 72 mg/L was the optimal cut-off point (Table 3), we further assessed the diagnostic values at different CRP levels alone and also in presence/absence of other clinical symptoms to understand the discriminatory analysis between definite bacterial pneumonia and viral and other pneumonia.

description: Recently, a class of gravitational backgrounds in 3+1 dimensions have been proposed as holographic duals to a Lifshitz theory describing critical phenomena in 2+1 dimensions with critical exponent $z\geq 1$. We numerically explore black holes in these backgrounds for a range of values of $z$. We find drastically different behavior for $z>2$ and $z<2$. We find that for $z>2$ ($z<2$) the Lifshitz fixed point is repulsive (attractive) when going to larger radial parameter $r$. For the repulsive $z>2$ backgrounds, we find a continuous family of black holes satisfying a finite energy condition. However, for $z<2$ we find that the finite energy condition is more restrictive, and we expect only a discrete set of black hole solutions, unless some unexpected cancellations occur. For all black holes, we plot temperature $T$ as a function of horizon radius $r_0$. For $z\lessapprox 1.761$ we find that this curve develops a negative slope for certain values of $r_0$ possibly indicating a thermodynamic instability.

Structural and magnetic properties of Fe-Co-C alloys with tetragonal deformation: a first-principle study

description: Fe-Co alloys with induced tetragonal strain are promising materials for rare-earth-free permanent magnets. However, as ultrathin-film studies have shown, tetragonal Fe-Co structures tend to a rapid relaxation toward a cubic structure as the thickness of the deposited film increases. One of the main methods of inducing the stable strain in the bulk material is interstitial doping with small atoms, like B, C, or N. In this work, we present a full configuration space analysis in density functional theory approach for (Fe$_{1-x}$Co$_x$)$_{16}$C supercells with a single C impurity in one of the octahedral interstitial positions and for the full range of Co concentrations $x$. We discuss all assumptions and considerations leading to calculated lattice parameters, mixing enthalpies, magnetic moments, and averaged magnetocrystalline anisotropy energies (MAE). We present a comprehensive qualitative analysis of the structural and magnetic properties' dependence on short- and long-range ordering parameters. We analyzed all unique Fe/Co atoms occupancies at all stoichiometric concentrations possible in 2x2x2 supercell based on 2-atom tetragonal representation. We rely on the thermodynamic averaging method and large sample count to obtain accurate MAE values. We reevaluate several chemical disorder approximation methods, including effective medium methods (virtual crystal approximation and coherent potential approximation) and special quasirandom structures method applied to Fe-Co-based alloys. We observe a structural phase transition from the body-centered tetragonal structure above 70% Co concentration and confirm the structural stability of Fe-Co-C alloys in the tetragonal range. We show the presence of a broad MAE maximum of around 50% Co concentration and notably high MAE values for Co content $x$ as low as 25%. In addition, we show a positive correlation between MAE and mixing enthalpy.

description: Let $(X,μ,T,d)$ be a metric measure-preserving dynamical system such that $3$-fold correlations decay exponentially for Lipschitz continuous observables. Given a sequence $(M_k)$ that converges to $0$ slowly enough, we obtain a strong dynamical Borel--Cantelli result for recurrence, i.e., for $μ$-a.e. $x\in X$ \[ \lim_{n \to \infty}\frac{\sum_{k=1}^{n} \mathbf{1}_{B_k(x)}(T^{k}x)} {\sum_{k=1}^{n} μ(B_k(x))} = 1, \] where $μ(B_k(x)) = M_k$. In particular, we show that this result holds for Axiom A diffeomorphisms and equilibrium states under certain assumptions.

We find the ratio of the average length of the perimeter and the accessible perimeter of a DLA cluster together with its external perimeters to the cluster size, and define a microscopic schematic procedure for attachment of an incident new particle to the cluster. We measure the fractal dimension of the red sites (i.e., the sites upon cutting each of them splits the cluster) equal to that of the DLA cluster. It is also shown that the average number of the dead sites and the average number of the red sites have linear relationships with the cluster size.

An Introduction to Lieb's Simplified approach to the Bose gas
Creators: name: Jauslin, Ian
Publisher: name: arXiv
Year: 2023
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: This is a book about Lieb's Simplified approach to the Bose gas, which is a family of effective single-particle equations to study the ground state of many-body systems of interacting Bosons. It was introduced by Lieb in 1963, and recently found to have some rather intriguing properties. One of the equations of the approach, called the Simple equation, has been proved to make a prediction for the ground state energy that is asymptotically accurate both in the low- and the high-density regimes. Its predictions for the condensate fraction, two-point correlation function, and momentum distribution also agree with those of Bogolyubov theory at low density, despite the fact that it is based on ideas that are very different from those of Bogolyubov theory. In addition, another equation of the approach called the Big equation has been found to yield numerically accurate results for these observables over the entire range of densities for certain interaction potentials.
 This book is an introduction to Lieb's Simplified approach, and little background knowledge is assumed. We begin with a discussion of Bose gases and quantum statistical mechanics, and the notion of Bose-Einstein condensation, which is one of the main motivations for the approach. We then move on to an abridged bibliographical overview on known theorems and conjectures about Bose gases in the thermodynamic limit. Next, we introduce Lieb's Simplified approach, and its derivation from the many-body problem. We then give an overview of results, both analytical and numerical, on the predictions of the approach. We then conclude with a list of open problems.

description: The effect of a magnetic field on the dipole echo amplitude in glasses at temperatures of about 10 mK caused by nonspherical nuclei with electric quadrupole moments has been studied theoretically. It has been shown that in this case, the two-level systems (TLS's) that determine the glass properties at low temperatures are transformed into more complicated multilevel systems. These systems have new properties as compared to usual TLS's and, in particular, exhibit oscillations of electric dipole echo amplitude in magnetic field. A general formula that describes the echo amplitude in an arbitrary split TLS has been derived with perturbation theory. Detailed analytic and numerical analysis of the formula has been performed. The theory agrees qualitatively and quantitatively well with experimental data.

Unlike the case of transversal magnetic fields, the linearized problem of our case is not well-posed in standard Sobolev space $H^m~(m\geq 2)$, while the incompressible problem is still well-posed in $H^m$. The key observation to overcome the difficulty is a hidden structure contributed by Lorentz force in the vorticity analysis, which reveals that one should trade one normal derivative for two tangential derivatives together with a gain of Mach number weight $\varepsilon^2$. Thus, the energy functional should be defined by using suitable anisotropic Sobolev spaces. The weights of Mach number should be carefully chosen according to the number of tangential derivatives, such that the energy estimates are uniform in Mach number. Besides, part of the proof is similar to the study of compressible water waves, so our result opens the possibility to study the incompressible limit of free-boundary problems in ideal MHD.

description: Background: Human immunodeficiency virus infection (HIV) is one of the major health burdens in Nigeria. Delayed HIV diagnosis remains a significant driver of HIV transmission. The causes of delayed diagnosis are unknown. This observational study investigated demographic risk factors for delayed HIV diagnosis, time from HIV infection to diagnosis and trends in the rate of positive HIV tests and delayed diagnosis in Ibadan, Nigeria. Methods: The Acquired immunodeficiency syndrome (AIDS) Prevention Initiative (APIN) database provided data on people living with HIV who enrolled for care between October 2013 and December 2018 at the Antiretroviral Therapy (ART) clinic in the University College Hospital, Ibadan, Nigeria. 3,458 patients aged 15 years or older, diagnosed with HIV for the first time, with available CD4 counts, were included in this study. Delayed HIV diagnosis was defined as the Cluster of Differentiation 4 (CD4) counts less than 350 cells/mm³ at the time of first diagnosis. An assessment of the association between the outcome variable (delayed HIV diagnosis) and the independent variables was conducted using logistic regression analysis to identify the risk factors for delayed HIV diagnosis, and the time interval between HIV infection and diagnosis was calculated based on the average CD4 decline rate. Results: A total of 3,458 patients were included. The prevalence of delayed HIV diagnosis was 1,993/3,458 (57.6%). Risk factors significantly associated with delayed HIV diagnosis in the multivariate analysis were older age, retiree, marriage separation, never married and widowed females. Risk factors significantly associated with an early HIV diagnosis were student and tertiary education. The mean time from infection to diagnosis was 6.3 years. A progressive decline in the rate of positive HIV tests and delayed HIV diagnosis were observed from 2014 to 2018. Conclusion: The rate of delayed HIV diagnosis was high but is declining with time. HIV testing implementation should focus on groups at risk of delayed diagnosis.

description: The paper discusses the three following subjects: first, the trend of European urbanisation from 1300 until 1600 (reassessing the existing literature on the topic); second, the immediate causes of this trend (on the basis of town-country differentials in labour productivity and wages); third, a model explaining this reconstructed trend on the basis of rural-urban interaction. The conclusion addresses the advantages and disadvantages of the macro and micro approaches to the history of towns in the late medieval to early modern periods.

description: Let $\mathbb{X}$ be a noetherian separated scheme $\mathbb{X}$ of finite Krull dimension which has enough locally free sheaves of finite rank and let $U\subseteq \mathbb{X}$ be an open subscheme. We prove that the singularity category of $U$ is triangle equivalent to the Verdier quotient category of the singularity category of $\mathbb{X}$ with respect to the thick triangulated subcategory generated by sheaves supported in the complement of $U$. The result unifies two results of D. Orlov. We also prove a noncommutative version of this result.

description: Quantum phase estimation (QPE) of the eigenvalues of a unitary operator on a target quantum system is a crucial subroutine in various quantum algorithms. Conventional QPE is often expensive to implement as it requires a large number of ancilla qubits and the ability to perform quantum Fourier transform. Recent developments in iterative QPE reduce the implementation cost by repetitive uses of a single ancilla and classical post-processing. However, both conventional and iterative schemes often require preparation of the target system in an eigenstate of the unitary operator, while it remains ambiguous to achieve QPE of multiple eigenvalues with no need of initial state preparation. Here we clarify this issue by developing a theoretical framework based on sequential quantum channels for iterative QPE. We find that QPE of multiple eigenvalues can be efficiently realized for arbitrary initial target system state by actively utilizing the measurement backaction of iterative QPE on the target system with a long coherence time. Specifically, we investigate two iterative QPE schemes based on sequential Ramsey interferometry measurements (RIMs) of an ancilla qubit: (a) the repetitive scheme, which conducts repetitive RIMs to achieve the standard quantum limit in estimating the eigenvalues; (b) the adaptive scheme, which adjusts the parameters of each RIM based on prior measurement outcomes to attain the Heisenberg limit. In both schemes, sequential ancilla measurements generate sequential quantum channels on the target system, gradually steering it to the eigenstates of the estimated unitary operator, while the measurement statistics of the ancilla can reveal the embedded information about its eigenvalues with proper post-processing. We demonstrate the analysis by simulating a central spin model, and evaluate the performance and noise resilience of both schemes.

description: Hundreds of both general purpose and discipline-specific repositories serve geoscience, bioscience, and anthroscience needs for data preservation, discovery, and access. These repositories serve overlapping communities of researchers, and each have been specialized to fit the needs of their particular audience. Some focus on fast and lightweight deposit using mainly bibliographic metadata, while others support deposit of complex datasets with detailed, domain-specific metadata to enable interpretation and reuse. Despite these differences, repositories also possess many common characteristics that should enable them to leverage shared infrastructure to decrease the cost of software development, maintenance, and operations. For example, many repositories within the DataONE network use the Metacat data repository platform for both data storage and access and the MetacatUI client application for metadata authoring, deposit, and discovery. Similar shared platforms exist within other networks such as Dataverse, GeoNetwork, and CKAN, while many other groups create their own custom, in-house software for repository data and metadata management. In this presentation, we outline some challenges to realizing shared software, services, and infrastructure among repositories, even with aligned missions, as well as the pathways that facilitate repository adoption of and contribution to shared, open source data management software. By sharing repository software and services, we see a pathway to both improving the sustainability of repository networks, and towards freeing up resources for innovative new services needed for effective data integration and reuse for science.

description: The recent discovery of copper-substituted lead phosphate apatite, also known as LK-99, has caught much attention owing to certain experimental evidence of room-temperature superconductivity, although this claim is currently under intensive debate. Be it superconducting or not, we show that the normal state of this material has peculiar quantum geometrical properties that may be related to the magnetism and the mechanism for flat band superconductivity. Based on a recently proposed spinless two-band tight-binding model for the Pb-Cu hexagonal lattice subset of the crystalline structure, which qualitatively captures the two flat bands in the band structure, we elaborate the highly anisotropic Berry curvature and quantum metric in the regions of Brillouin zone where one flat band is above and the other below the Fermi surface. In these regions, the Berry curvature has a pattern in the planar momentum that remains unchanged along the out-of-plane momentum. Moreover, the net orbital magnetization contributed from the Berry curvature is zero, signifying that the magnetism in this material should come from other sources. The quantum metric has a similar momentum dependence, and its two planar components are found to be roughly the same but the out-of-plane component vanishes, hinting that the superfluid stiffness of the flat band superconductivity, shall it occur, may be quite anisotropic.

description: The relation between the dynamical regimes (weak and strong coupling) and entanglement for a dissipative quantum - dot microcavity system is studied. In the framework of a phenomenological temperature model an analysis in both, temporal (population dynamics) and frequency domain (photoluminescence) is carried out in order to identify the associated dynamical behavior. The Wigner function and concurrence are employed to quantify the entanglement in each regime. We find that sudden death of entanglement is a typical characteristic of the strong coupling regime.
