description: We consider the problem of determination of the Gelfand-Tsetlin basis for unitary principal series representations of the Lie algebra $gl_n(\mathbb{C})$. The Gelfand-Tsetlin basis for an infinite-dimensional representation can be defined as the basis of common eigenfunctions of corner quantum minors of the corresponding L-operator. The construction is based on the induction with respect to the rank of the algebra: an element of the basis for $gl_n(\mathbb{C})$ is expressed in terms of a Mellin-Barnes type integral of an element of the basis for $gl_{n-1}(\mathbb{C})$. The integration variables are the parameters (in other words, the quantum numbers) setting the eigenfunction. Explicit results are obtained for ranks $3$ and $4$, and the orthogonality of constructed sets of basis elements is demonstrated. For $gl_3(\mathbb{C})$ the kernel of the integral is expressed in terms of gamma-functions of the parameters of eigenfunctions, and in the case of $gl_4(\mathbb{C})$ -- in terms of a hypergeometric function of the complex field at unity. The formulas presented for an arbitrary rank make it possible to obtain the system of finite-difference equations for the kernel. They include expressions for the quantum minors of $gl_n(\mathbb{C})$ L-operator via the minors of $gl_{n-1}(\mathbb{C})$ L-operator for the principal series representations, as well as formulas for action of some non-corner minors on the eigenfunctions of corner ones. The latter hold for any representation of $gl_n(\mathbb{C})$ (not only principal series) in which the corner minors of the L-operator can be diagonalized.

description: Objective: Blood transfusions, crucial in managing anemia and coagulopathy in ICU settings, require accurate prediction for effective resource allocation and patient risk assessment. However, existing clinical decision support systems have primarily targeted a particular patient demographic with unique medical conditions and focused on a single type of blood transfusion. This study aims to develop an advanced machine learning-based model to predict the probability of transfusion necessity over the next 24 hours for a diverse range of non-traumatic ICU patients.
 Methods: We conducted a retrospective cohort study on 72,072 adult non-traumatic ICU patients admitted to a high-volume US metropolitan academic hospital between 2016 and 2020. We developed a meta-learner and various machine learning models to serve as predictors, training them annually with four-year data and evaluating on the fifth, unseen year, iteratively over five years.
 Results: The experimental results revealed that the meta-model surpasses the other models in different development scenarios. It achieved notable performance metrics, including an Area Under the Receiver Operating Characteristic (AUROC) curve of 0.97, an accuracy rate of 0.93, and an F1-score of 0.89 in the best scenario.
 Conclusion: This study pioneers the use of machine learning models for predicting blood transfusion needs in a diverse cohort of critically ill patients. The findings of this evaluation confirm that our model not only predicts transfusion requirements effectively but also identifies key biomarkers for making transfusion decisions.

description: We study kink-antikink scattering in the sine-Gordon model in the presence of interactions with an additional scalar field, $ψ$, that is in its quantum vacuum. In contrast to the classical scattering, now there is quantum radiation of $ψ$ quanta and the kink-antikink may form bound states that resemble breathers of the sine-Gordon model. We quantify the rate of radiation and map the parameters for which bound states are formed. Even these bound states radiate and decay, and eventually there is a transition into long-lived oscillons.

description: Little is known about the coupling of rotation and translation in dense systems. Here, we report results of confocal fluorescence microscopy where simultaneous recording of translational and rotational particle trajectories from a bidisperse colloidal dispersion is achieved by spiking the samples with rotational probe particles. The latter consist of colloidal particles containing two fluorescently labelled cores suited for tracking the particle's orientation. A comparison of the experimental data with event driven Brownian simulations gives insight into the system's structure and dynamics close to the glass transition and sheds new light onto the translation-rotation coupling. The data show that with increasing volume fractions, translational dynamics slows down drastically, whereas rotational dynamics changes very little. We find convincing agreement between simulation and experiments, even though the simulations neglect far-field hydrodynamic interactions. An additional analysis of the glass transition following mode coupling theory works well for the structural dynamics but indicates a decoupling of the diffusion of the smaller particle species. The shear stress correlations do not decorrelate in the simulated glass states and are not affected by rotational motion.

description: In the development of quantum technologies, a reliable means for characterizing quantum devices is crucial. However, the conventional approach based on, e.g., quantum state tomography or process tomography relies on assumptions often not necessarily justifiable in a realistic experimental setting. While the device-independent approach to this problem bypasses the shortcomings above by making only minimal, justifiable assumptions, most of the theoretical proposals to date only work in the idealized setting where i.i.d. trials are assumed. Here, we provide a versatile solution for rigorous device-independent certification that does not rely on the i.i.d. assumption. Specifically, we describe how the prediction-based-ratio (PBR) protocol and martingale-based protocol developed for hypothesis testing can be applied in the present context to achieve a device-independent certification of desirable properties with confidence interval. To illustrate the versatility of these methods, we demonstrate how we can use them to certify, with finite data, the underlying negativity, Hilbert space dimension, entanglement depth, and fidelity to some target pure state. In particular, we give examples showing how the amount of certifiable negativity and fidelity scales with the number of trials, and how many experimental trials one needs to certify a qutrit state space, or the presence of genuine tripartite entanglement. Overall, we have found that the PBR protocol and the martingale-based protocol often offer similar performance, even though the former does have to presuppose any witness. In contrast, our findings also show that the performance of the martingale-based protocol may be severely affected by one's choice of the witness. Intriguingly, a witness useful for self-testing does not necessarily give the optimal confidence-gain rate for certifying the fidelity to the corresponding target state.

The inhabitants of Sondup’o do not have a formal, organized religion but rather a practice of ancestor worship (with roots in Shamanism) influenced by Confucianism and Buddhism. This spiritual ideology permeates most aspects of life, so the society is best characterized as coterminous with the religious group.

description: Time-uniform log-Sobolev inequalities (LSI) satisfied by solutions of semi-linear mean-field equations have recently appeared to be a key tool to obtain time-uniform propagation of chaos estimates. This work addresses the more general settings of time-inhomogeneous Fokker-Planck equations. Time-uniform LSI are obtained in two cases, either with the bounded-Lipschitz perturbation argument with respect to a reference measure, or with a coupling approach at high temperature. These arguments are then applied to mean-field equations, where, on the one hand, sharp marginal propagation of chaos estimates are obtained in smooth cases and, on the other hand, time-uniform global propagation of chaos is shown in the case of vortex interactions with quadratic confinement potential on the whole space. In this second case, an important point is to establish global gradient and Hessian estimates, which is of independent interest. We prove these bounds in the more general situation of non-attractive logarithmic and Riesz singular interactions.

This report analyses the drivers of violence in Nigeria’s Nasarawa State in order to understand the broader dynamics of conflict across the country’s Middle Belt region. Based on an exploration of documentary evidence and interviews with community members affected by conflict, it highlights the complexity of reducing violence and the importance of action in multiple areas simultaneously, while recognising the geographic variations in conflict drivers, actors, and dynamics. The report concludes with practical recommendations for Nasarawa’s leaders to act upon.

description: High-coherence qubits, which can store and manipulate quantum states for long times with low error rates, are necessary building blocks for quantum computers. Here we propose a driven superconducting erasure qubit, the Floquet fluxonium molecule, which minimizes bit-flip rates through disjoint support of its qubit states and suppresses phase flips by a novel second-order insensitivity to flux-noise dephasing. We estimate the bit-flip, phase-flip, and erasure rates through numerical simulations, with predicted coherence times of approximately 50 ms in the computational subspace and erasure lifetimes of about 500 $μ$s. We also present a protocol for performing high-fidelity single-qubit rotation gates via additional flux modulation, on timescales of roughly 500 ns, and propose a scheme for erasure detection and logical readout. Our results demonstrate the utility of drives for building new qubits that can outperform their static counterparts.

Analytical results for the Quantum Alternating Operator Ansatz with Grover Mixer

description: An important property of QAOA with Grover mixer is that its expectation value is invariant over any permutation of states. As a consequence, the algorithm is independent of the structure of the problem. If, on the one hand, this characteristic raises serious doubts about the capacity of the algorithm to overcome the bound of the unstructured search problem, on the other hand, it can pave the way to its analytical study. In this sense, a prior work introduced a statistical approach to analyze GM-QAOA that results in an analytical expression for the expectation value depending on the probability distribution associated with the problem Hamiltonian spectrum. Although the method provides surprising simplifications in calculations, the expression depends exponentially on the number of layers, which makes direct analytical treatment unfeasible. In this work, we extend the analysis to the more simple context of Grover Mixer Threshold QAOA (GM-Th-QAOA), a variant that replaces the phase separation operator of GM-QAOA to encode a threshold function. As a result, we obtain an expression for the expectation value independent of the number of layers and, with it, we provide bounds for different performance metrics. Furthermore, we extend the analysis to a more general context of QAOA with Grover mixer, which we called Grover-based QAOA. In that framework, which allows the phase separation operator to encode any compilation of the cost function, we generalize all the bounds by using an argument by contradiction with the optimality of Grover's algorithm on the unstructured search problem. As a result, we get the main contribution of this work, an asymptotic lower bound on the quantile achieved by the expectation value that formalizes the notion that the Grover mixer, at most, reflects a quadratic Grover-style speed-up over classical brute force.

description: The Javanese are Indonesia's largest ethnic group, and live primarily in East and Central Java (Martin, 2010). Java has a longtime history of contact with other cultures. Indian and Chinese influence and trade have been present since the eighth century, and have brought Islamic and Buddhist religious beliefs. The Dutch gained control over Java in the eighteenth century, which lasted until Indonesia gained sovereignty in 1949 (Martin, 2010). With such a variety of contact, the Javanese religious beliefs are, unsurprisingly, predominantly syncretic. Three main religious traditions are present: the santri (purer Islamic subtradition), the prijaji (mainly stresses Hindu beliefs), and the abangan (integration of animism, Hundu, Buddhist, and Islamic beliefs) (Geertz, 1960:5). This entry focuses on the syncretic beliefs of the abangan Javanese. It is important to stress the variation and complexity of spiritual life in Java, as Java is "not easily characterized under a single label or easily pictured in terms of a dominant theme. It is particularly true that in describing the religion of such a complex civilization as the Javanese any simple unitary view is certain to be inadequate..." (Geertz, 1960:7).

description: Large language models (LLMs)such as ChatGPT have significantly advanced the field of Natural Language Processing (NLP). This trend led to the development of code-based large language models such as StarCoder, WizardCoder, and CodeLlama, which are trained extensively on vast repositories of code and programming languages. While the generic abilities of these code LLMs are useful for many programmers in tasks like code generation, the area of high-performance computing (HPC) has a narrower set of requirements that make a smaller and more domain-specific model a smarter choice. This paper presents OMPGPT, a novel domain-specific model meticulously designed to harness the inherent strengths of language models for OpenMP pragma generation. Furthermore, we leverage prompt engineering techniques from the NLP domain to create Chain-of-OMP, an innovative strategy designed to enhance OMPGPT's effectiveness. Our extensive evaluations demonstrate that OMPGPT outperforms existing large language models specialized in OpenMP tasks and maintains a notably smaller size, aligning it more closely with the typical hardware constraints of HPC environments. We consider our contribution as a pivotal bridge, connecting the advantage of language models with the specific demands of HPC tasks.

description: We propose an effective framework for computing the prepotential of the topological B-model on a class of local Calabi--Yau geometries related to the circle compactification of five-dimensional $\mathcal{N}=1$ super Yang--Mills theory with simple gauge group. In the simply-laced case, we construct Picard--Fuchs operators from the Dubrovin connection on the Frobenius manifolds associated to the extended affine Weyl groups of type $\mathrm{ADE}$. In general, we propose a purely algebraic construction of Picard--Fuchs ideals from a canonical subring of the space of regular functions on the ramification locus of the Seiberg--Witten curve, encompassing non-simply-laced cases as well. We offer several precision tests of our proposal. Whenever a candidate spectral curve is known from string theory/brane engineering, we perform non-perturbative comparisons with the gauge theory prepotentials obtained from the K-theoretic blow-up equations, finding perfect agreement. We also employ our formalism to rule out some proposals from the theory of integrable systems of Seiberg--Witten geometries for non-simply laced gauge groups.

description: The kagome metal compounds $A$V$_3$Sb$_5$ ($A$ = K, Rb, and Cs) feature a wealth of phenomena including nontrivial band topology, charge density wave (CDW), and superconductivity. One intriguing property is the time-reversal symmetry breaking in the CDW state without local moments, which leads to anomalous transport responses. Here, we report the investigation of magneto-thermoelectric effects on high-quality CsV$_3$Sb$_5$ single crystals. A large anomalous Nernst effect is observed at temperatures below 30 K. Multiple Fermi surfaces with small effective masses are revealed by quantum oscillations in Nernst and Seebeck signals under high magnetic field. Furthermore, we find an unknown frequency, and attribute it to the magnetic breakdown across two smaller Fermi surfaces. A gap around 20 meV can be resolved from the breakdown threshold field, which we propose to be introduced by the CDW. These results shed new light on the CDW-related phenomena, particularly in $A$V$_3$Sb$_5$ compounds.

description: Instance segmentation of compound objects in XXL-CT imagery poses a unique challenge in non-destructive testing. This complexity arises from the lack of known reference segmentation labels, limited applicable segmentation tools, as well as partially degraded image quality. To asses recent advancements in the field of machine learning-based image segmentation, the "Instance Segmentation XXL-CT Challenge of a Historic Airplane" was conducted. The challenge aimed to explore automatic or interactive instance segmentation methods for an efficient delineation of the different aircraft components, such as screws, rivets, metal sheets or pressure tubes. We report the organization and outcome of this challenge and describe the capabilities and limitations of the submitted segmentation methods.

description: We compute exactly the full distribution of the number $m$ of local minima in a one-dimensional landscape generated by a random walk or a Lévy flight. We consider two different ensembles of landscapes, one with a fixed number of steps $N$ and the other till the first-passage time of the random walk to the origin. We show that the distribution of $m$ is drastically different in the two ensembles (Gaussian in the former case, while having a power-law tail in the latter $m^{-3/2}$ in the latter case). However, the most striking aspect of our results is that, in each case, the distribution is completely universal for all $m$ (and not just for large $m$), i.e., independent of the jump distribution in the random walk. This means that the distributions are exactly identical for Lévy flights and random walks with finite jump variance. Our analytical results are in excellent agreement with our numerical simulations.

description: We perform the first model independent analysis of experimental data using Deep Neural Networks to determine the nature of an exotic hadron. Specifically, we study the line shape of the $P_c(4312)$ signal reported by the LHCb collaboration and we find that its most likely interpretation is that of a virtual state. This method can be applied to other near-threshold resonance candidates.

Examination of Resistance Settings Based on Body Weight for the 3-Minute All-Out Critical Power Test
Creators: name: Schulte, Marlene
Publisher: name: University of Kentucky
Year: 2016
Subjects: subject: Health and Physical Education

description: This study examined whether the critical power (CP) and anaerobic work capacity (AWC) estimates from the CP 3-min all-out (CP3min) test were affected by the percentage of body weight used to set the resistance on a Monark cycle ergometer. Twenty-one subjects (11 women and 10 men) were placed into one of three groups (n=7) based on activity level; recreationally trained (REC), aerobic and anaerobic sport (SPORT), and endurance trained (END). The CP3min test was conducted at 4.5% of body weight (CP4.5%) and at a resistance setting based on group activity level (CPACT; REC = 3%, SPORT = 4%, and END = 5% of body weight). There were no differences between the CP4.5% or CPACT estimates in any of the three training groups. The AWC3% estimates were significantly lower than the AWC4.5% for the REC group, but there were no differences in the AWC4.5% and AWCACT for the SPORT or END groups.The principal finding of this study was that a resistance of 4.5% of body weight for CP3-min test may be used to estimate CP and AWC, without regard to the training status of the subjects.
Fractionalization and anyonic statistics in the integer quantum Hall collider

description: One remarkable feature of strongly correlated systems is the phenomenon of fractionalization where quasiparticles carry only a fraction of the charge or spin of the elementary constituents. Such quasiparticles often present anyonic statistics in two dimensions and lie at the heart of the fractional quantum Hall effect. We discuss the observation of fractionalization and anyonic statistics already in the integer quantum Hall effect coupled to a metallic island. A continuous fractional emitter is proposed, which sends dilute beams of non-integer charges, and its full counting statistics is obtained. The fractional charge is governed solely by the number of ballistic channels covered by the island and it is one half of the electron charge for a single ballistic channel. We further characterize the mixing of two such fractional beams through a quantum point contact beam splitter. We predict negative cross-correlations, in strong contrast with free electrons, that depend on the double exchange phase between electrons and the fractional charges emulating anyons. The result is similar to a genuine fractional edge state as recently measured at filling $ν= 1/3$. We revisit the physical interpretation of this experiment and point towards a direct braiding measurement rather than a deviation from fermionic antibunching.

description: Deciphering the interplay between confinement effects and intermolecular interactions in zeolites is crucial for understanding diverse diffusion behaviors of confined molecules. Recent studies explored the impact of water and CO$_2$ on hydrocarbon dynamics in nanoporous materials. However, differing nanoporous materials, as used in these studies complicate the comparative analysis of CO$_2$ and water effects on hydrocarbons, necessitating a comprehensive investigation with identical confining media and consistent pore diameters. In this study, we investigate the diffusion of ethane, CO$_2$, and water in ZSM-22 molecular sieves. Additionally, we examine the effect of hydration and CO$_2$ on ethane diffusion through the study of ethane-water and ethane-CO$_2$ mixtures. Results indicate enhanced translational motions of CO$_2$ in mixtures, while CO$_2$ minimally affects ethane diffusion. In contrast, water is found to slow down the diffusion of ethane by making molecular bridges across the pores. Ethane hampers the translational dynamics of water molecules. Hydrogen bonding in water and the molecular polarity of the fluids are found to play an important role in determining the effects of the presence of one species on the motion of the other. Rotation of the fluid molecules in ZSM-22 is found to occur at two-time scales in both pure state as well as in fluid mixtures. While the short-time fast rotation is determined by the moment of inertia, the long-time rotation is affected by the interaction between fluid molecules and the zeolite atoms. In the case of water, hydrogen bonding hinders rotation and inhibits complete rotation.

description: Density functional theory is routinely applied to predict crystal structures. The most common exchange-correlation functionals used to this end are the Perdew-Burke-Ernzerhof (PBE) approximation and its variant PBEsol. We investigate the performance of these functionals for the prediction of lattice parameters and show how to enhance their accuracy using machine learning. Our dataset is constituted by experimental crystal structures of the Inorganic Crystal Structure Database matched with PBE-optmized structures stored in the materials project database. We complement these data with PBEsol calculations. We demonstrate that the accuracy and precision of PBE/PBEsol volume predictions can be noticeably improved a posteriori by employing simple, explainable machine learning models. These models can improve PBE unit cell volumes to match the accuracy of PBEsol calculations, and reduce the error of the latter with respect to experiment by 35%. Further, the error of PBE lattice constants is reduced by a factor of 3--5. A further benefit of our approach is the implicit correction of finite temperature effects without performing phonon calculations.

description: We report on singular and nonsingular flat bands in a Sierpinski fractal-like photonic lattice. We demonstrate that the the lowest two bands, being isolated and degenerate due to geometrical frustration, are nonsingular and thus can be spanned by a complete set of compact localized states. We experimentally prove these states to propagate diffractionless in the photonic lattice. Our results reveal the interplay between geometrical frustration, degenerate flat bands and compact localized states in a single photonic lattice, and pave the way to photonic spin liquid ground states.
