description: Single- and few-layered InSe flakes are produced by the liquid-phase exfoliation of beta-InSe single crystals in 2-propanol, obtaining stable dispersions with a concentration as high as 0.11 g/L. Ultracentrifugation is used to tune the morphology, i.e., the lateral size and thickness of the as-produced InSe flakes. We demonstrate that the obtained InSe flakes have maximum lateral sizes ranging from 30 nm to a few um, and thicknesses ranging from 1 to 20 nm, with a max population centred at ~ 5 nm, corresponding to 4 Se-In-In-Se quaternary layers. We also show that no formation of further InSe-based compounds (such as In2Se3) or oxides occurs during the exfoliation process. The potential of these exfoliated-InSe few-layer flakes as a catalyst for hydrogen evolution reaction (HER) is tested in hybrid single-walled carbon nanotubes/InSe heterostructures. We highlight the dependence of the InSe flakes morphologies, i.e., surface area and thickness, on the HER performances achieving best efficiencies with small flakes offering predominant edge effects. Our theoretical model unveils the origin of the catalytic efficiency of InSe flakes, and correlates the catalytic activity to the Se vacancies at the edge of the flakes.

Descriptive Study of New Jersey's System for External Foster Care Case Review

description: Effective October 1, 1978, New Jersey mandated independent review of all out-of-home placements supervised and approved for payment by the Division of Youth and Family Services (DYFS). The law authorized each county's Superior Court Assignment Judges to appoint five-member Child Placement Review Boards who must make recommendations to the judge within 45 days of the child's entry into care; all cases must be reviewed at least annually.

Semi-structured telephone interviews with members of 36 Boards and 26 persons from DYFS some two years after review was implemented indicated that the Boards varied greatly in the degree to which they exercised their authority. Boards which assumed an independent role were more likely to (1) require DYFS workers to give testimony on all cases; (2) meet weekly; (3) review at least 12 cases at each meeting; (4) have contact with their judge; and (5) reschedule cases before the next mandated annual review. This latter practice, commonly known as "re-review" or "relist", probably did more to demonstrate the Boards' independent role than formal disagreements with DYFS. Formal disagreements were relatively infrequent, presumably because most children were in the only care arrangement possible. Re-review, on the other hand, recognized the impracticability of immediate return home or adoption but held DYFS accountable for taking timely action to ensure permanence for children.

The study described the various ways local DYFS offices prepared for review and local Board-DYFS relationships.

The impact of review was considered by eliciting respondents' assessments of review. All 36 Board respondents and all but four DYFS respondents felt that DYFS gave more careful attention to case planning because they knew they would have to report to an outside body. Fourteen Board respondents and 24 DYFS liaisons identified at least one disadvantage.

The study concludes with an endorsement for independent review and offers recommendations for strengthening it. The study recommends that further research be undertaken to more rigorously study the effects of review.

description: The task of image generation started to receive some attention from artists and designers to inspire them in new creations. However, exploiting the results of deep generative models such as Generative Adversarial Networks can be long and tedious given the lack of existing tools. In this work, we propose a simple strategy to inspire creators with new generations learned from a dataset of their choice, while providing some control on them. We design a simple optimization method to find the optimal latent parameters corresponding to the closest generation to any input inspirational image. Specifically, we allow the generation given an inspirational image of the user choice by performing several optimization steps to recover optimal parameters from the model's latent space. We tested several exploration methods starting with classic gradient descents to gradient-free optimizers. Many gradient-free optimizers just need comparisons (better/worse than another image), so that they can even be used without numerical criterion, without inspirational image, but with only with human preference. Thus, by iterating on one's preferences we could make robust Facial Composite or Fashion Generation algorithms. High resolution of the produced design generations are obtained using progressive growing of GANs. Our results on four datasets of faces, fashion images, and textures show that satisfactory images are effectively retrieved in most cases.

description: Background New technologies offer great opportunities for health care systems but can also represent significant costs. Increasing the usage and development of medical technologies balancing cost and utility is a priority for many health care managers. Ensuring maximised diffusion and uptake of new technologies can be positively impacted by the degree of involvement of end-users in the purchasing and/or development of new products. While the idea that culture can promote or inhibit innovation is not new, innovation in the health care setting has only relatively recently been explored. Little information specific to university hospitals and procurement of innovation exists. The global COVID-19 pandemic has furthermore greatly influenced healthcare in the last months including medical procurement and innovation. This protocol details a planned qualitative research study to explore cultural factors influencing innovation at European university hospitals as well as the recent impact of the COVID-19 pandemic in depth. Methods Key informant interviews will be conducted at ten European university hospitals. The semi-structured interview guide includes questions on: the perspectives and experiences of staff in relation to the procurement of innovation; examples of past or ongoing projects in this area or in the area of digital health innovation; and changes related to COVID-19. Participant characteristics will be summarised with descriptive statistics. Multi-step thematic analysis using meaning condensation will be used to analyse transcribed data. Identified concepts will be linked with existing theories and/or factors identified by literature search. Results will be presented in narrative and table formats. Historical public procurement data will be downloaded from the European Union’s public procurement records portal TED. Trends from during COVID-19 will be statistically analysed in comparison to prior years. Discussion This manuscript describes the steps of our proposed qualitative study to explore cultural factors that contribute to successful and/or unsuccessful innovation in relation to digital health procurement, and the impact of COVID-19 on this field. Results will be used to provide points for consideration when conducting procurement of innovation, an important tool that organisations can use to drive digital research and development and a policy goal for the EU.

description: A new framework for $A(d,p)B$ reactions is introduced by merging the microscopic approach to computing the properties of the nucleon-target systems and the three-body $n+p+A$ reaction formalism, thus providing a consistent link between the reaction cross sections and the underlying microscopic structure. In this first step toward a full microscopic description, we focus on the inclusion of the neutron-target microscopic properties. The properties of the neutron-target subsystem are encapsulated in the Green's function which is computed with the Coupled Cluster theory using a chiral nucleon-nucleon and three-nucleon interactions. Subsequently, this many-body information is introduced in the few-body Green's Function Transfer approach to $(d,p)$ reactions. Our benchmarks on stable targets $^{40,48}$Ca show an excellent agreement with the data. We then proceed to make specific predictions for $(d,p)$ on neutron rich $^{52,54}$Ca isotopes. These predictions are directly relevant to testing the new magic numbers $N=32,34$ and are expected to be feasible in the first campaign of the projected FRIB facility.

Invariants of fibred knots from moduli

description: An invariant $μ_α(K)$ of fibred knots $K$ in a homology sphere is defined for each $α\in {\bold S}{\bold U}_n$ as follows. Since the knot is fibred, the knot complement is described by an element of the mapping class group, which induces an action on the variety of ${\bold S}{\bold U}_n$ representations of the surface group. Restricting attention to those representations with holonomy along the longitude conjugate to $a \in {\bold S}{\bold U}_n,$ one can define $μ_α(K)$ to be the Lefschetz number of this action. The dependence of $μ_α(K)$ on $α$ is studied and formulas relating $μ_α(K)$ to $μ_β(K)$ are derived for $α,β\in ${\bold S}{\bold U}_n$.$

description: Commit messages are crucial for documenting software changes, aiding in program comprehension and maintenance. However, creating effective commit messages is often overlooked by developers due to time constraints and varying levels of documentation skills. Our research presents an automated approach to generate commit messages using Machine Learning (ML) and Natural Language Processing (NLP) by developing models that use techniques such as Logistic Regression with TF-IDF and Word2Vec, as well as more sophisticated methods like LSTM. We used the dataset of code changes and corresponding commit messages that was used by Liu et al., which we used to train and evaluate ML/NLP models and was chosen because it is extensively used in previous research, also for comparability in our study. The objective was to explore which ML/NLP techniques generate the most effective, clear, and concise commit messages that accurately reflect the code changes. We split the dataset into training, validation, and testing sets and used these sets to evaluate the performance of each model using qualitative and quantitative evaluation methods. Our results reveal a spectrum of effectiveness among these models, with the highest BLEU score achieved being 16.82, showcasing the models' capability in automating a clear and concise commit message generation. Our paper offers insights into the comparative effectiveness of different machine learning models for automating commit message generation in software development, aiming to enhance the overall practice of code documentation.

description: We explore the phenomenology of models containing one Vector-Like Quark (VLQ), $t'$, which can decay into the Standard Model (SM) top quark, $t$, and a new spin-0 neutral boson, $S$, the latter being either a scalar or pseudoscalar state. We parametrise the underlying interactions in terms of a simplified model which enables us to capture possible Beyond the SM (BSM) scenarios. We discuss in particular three such scenarios: one where the SM state is supplemented by an additional scalar, one which builds upon a 2-Higgs Doublet Model (2HDM) framework and another which realises a Composite Higgs Model (CHM) through partial compositeness. Such exotic decays of the $t'$ can be competitive with decays into SM particles, leading to new possible discovery channels at the Large Hadron Collider (LHC). Assuming $t'$ pair production via strong interactions, we design signal regions optimised for one $t'\rightarrow S t$ transition (while being inclusive on the other \bar{t'} decay, and vice versa), followed by the decay of $S$ into the two very clean experimental signatures $S\rightarrow γγ$ and $S\rightarrow Z(\rightarrow \ell^+\ell^-)γ$. We perform a dedicated signal-to-background analysis in both channels, by using Monte Carlo (MC) event simulations modelling the dynamics from the proton-proton to the detector level. Under the assumption of BR$(t' \rightarrow S t) = 100\%$, we are therefore able to realistically quantify the sensitivity of the LHC to both the $t'$ and $S$ masses, assuming both current and foreseen luminosities. This approach paves the way for the LHC experiments to surpass current VLQ search strategies based solely on $t'$ decays into SM bosons ($W^\pm, Z$, $h$).

An Energy-Efficient Resource Management System for a Mobile Ad Hoc Cloud

description: Recently, mobile ad hoc clouds have emerged as a promising technology for mobile cyber-physical system applications, such as mobile intelligent video surveillance and smart homes. Resource management plays a key role in maximizing resource utilization and application performance in mobile ad hoc clouds. Unlike resource management in traditional distributed computing systems, such as clouds, resource management in a mobile ad hoc cloud poses numerous challenges owing to the node mobility, limited battery power, high latency, and the dynamic network environment. The real-time requirements associated with mobile cyber-physical system applications make the problem even more challenging. Currently, existing resource management systems for mobile ad hoc clouds are not designed to support mobile cyber-physical system applications and energy-efficient communication between application tasks. In this paper, we propose a new energy-efficient resource management system for mobile ad hoc clouds. The proposed system consists of two layers: a network layer and a middleware layer. The network layer provides ad hoc network and communication services to the middleware layer and shares the collected information in order to allow efficient and robust resource management decisions. It uses (1) a transmission power control mechanism to improve energy efficiency and network capacity, (2) link lifetimes to reduce communication and energy consumption costs, and (3) link quality to estimate data transfer times. The middleware layer is responsible for the discovery, monitoring, migration, and allocation of resources. It receives application tasks from users and allocates tasks to nodes on the basis of network and node-level information.

On the product dimension of clique factors

Publisher: name: arXiv

description: The product dimension of a graph $G$ is the minimum possible number of proper vertex colorings of $G$ so that for every pair $u,v$ of non-adjacent vertices there is at least one coloring in which $u$ and $v$ have the same color. What is the product dimension $Q(s,r)$ of the vertex disjoint union of $r$ cliques, each of size $s$? Lovász, Nešetřil and Pultr proved in 1980 that for $s=2$ it is $(1+o(1)) \log_2 r$ and raised the problem of estimating this function for larger values of $s$. We show that for every fixed $s$, the answer is still $(1+o(1)) \log_2 r$ where the $o(1)$ term tends to $0$ as $r$ tends to infinity, but the problem of determining the asymptotic behavior of $Q(s,r)$ when $s$ and $r$ grow together remains open. The proof combines linear algebraic tools with the method of Gargano, Körner, and Vaccaro on Sperner capacities of directed graphs.

description: This paper explores the evolving relationship between clinician trust in LLMs, the transformation of data sources from predominantly human-generated to AI-generated content, and the subsequent impact on the precision of LLMs and clinician competence. One of the primary concerns identified is the potential feedback loop that arises as LLMs become more reliant on their outputs for learning, which may lead to a degradation in output quality and a reduction in clinician skills due to decreased engagement with fundamental diagnostic processes. While theoretical at this stage, this feedback loop poses a significant challenge as the integration of LLMs in healthcare deepens, emphasizing the need for proactive dialogue and strategic measures to ensure the safe and effective use of LLM technology. A key takeaway from our investigation is the critical role of user expertise and the necessity for a discerning approach to trusting and validating LLM outputs. The paper highlights how expert users, particularly clinicians, can leverage LLMs to enhance productivity by offloading routine tasks while maintaining a critical oversight to identify and correct potential inaccuracies in AI-generated content. This balance of trust and skepticism is vital for ensuring that LLMs augment rather than undermine the quality of patient care. Moreover, we delve into the potential risks associated with LLMs' self-referential learning loops and the deskilling of healthcare professionals. The risk of LLMs operating within an echo chamber, where AI-generated content feeds into the learning algorithms, threatens the diversity and quality of the data pool, potentially entrenching biases and reducing the efficacy of LLMs.

description: The Higgs boson can mix with a singlet scalar that dynamically generates the Majorana mass of the right-handed neutrino $N_R$. We show that even a tiny mixing between the Higgs boson and a `decoupled' singlet scalar allows for Higgs-mediated pair production of $N_R$ without significant mixings between the active neutrinos and $N_R$, and thus testable at colliders via a characteristic signal of two same-sign same-flavor lepton pairs, plus missing energy. We demonstrate that this search channel is mostly background-free in $pp$-collision and can be a highly sensitive probe of the Higgs-singlet mixing at the current and future $pp$ colliders. Such channel provides a clean signal to discover the singlet scalar and explore the origin of neutrino masses.

description: We consider $3$-dimensional isolated horizons (IHs) generated by null curves that form nontrivial $U(1)$ bundles. We find a natural interplay between the IH geometry and the $U(1)$-bundle geometry. In this context we consider the Petrov type D equation introduced and studied in previous works \cite{DLP1,DLP2,LS,DKLS1}. From the $4$-dimensional spacetime point of view, solutions to that equation define isolated horizons embeddable in vacuum spacetimes (with cosmological constant) as Killing horizons to the second order such that the spacetime Weyl tensor at the horizon is of the Petrov type D. From the point of view of the $U(1)$-bundle structure, the equation couples a $U(1)$-connection, a metric tensor defined on the base manifold and the surface gravity in a very nontrivial way. We focus on the $U(1)$-bundles over $2$-dimensional manifolds diffeomorphic to $2$-sphere. We have derived all the axisymmetric solutions to the Petrov type D equation. For a fixed value of the cosmological constant they set a $3$-dimensional family as one could expect. A surprising result is, that generically our horizons are not embeddable in the known exact solutions to Einstein's equations. It means that among the exact type D spacetimes there exists a new family of spacetimes that generalize the properties of the Kerr- (anti) de Sitter black holes on one hand and the Taub-NUT spacetimes on the other hand.

description: We explore here a possible consequence of crustquake, namely, the generation of bursts of gravitational waves (GWs) due to a sudden change in the quadrupole moment (QM) of a deformed pulsar as a result of crustquake. The occurrence of crustquake in a rotating neutron star can play many important roles in neutron star (NS) dynamics. Here we propose that if a pulsar undergoes crustquake, then the generation of bursts of GWs is an inevitable consequence of crustquake. We have estimated the strain amplitudes ($h_0$) for such bursts of GWs and compared with the strain amplitudes for GWs produced in various other scenarios for isolated pulsars as suggested earlier in the literature. The values we obtain are comparable to those suggestions. We also estimate the order of magnitude for characteristic strain ($h_c$) and signal to noise ratio (SNR) for such bursts. For exotic quarks stars, a multifold enhancement of strain amplitudes is expected, which makes quark stars a potential source of gravitational waves as a result of crustquake. The absence of such waves may put constraints on such hypothetical stars

description: Connectedness percolation phenomena in the two-dimensional (2D) packing of binary mixtures of disks with different diameters were studied numerically. The packings were produced using random sequential adsorption (RSA) model with simultaneous deposition of disks. The ratio of the particle diameters was varied within the range $D=1$-$10$, and the selection probability of the small disks was varied within the range 0-1. A core-shell structure of the particles was assumed for the analysis of connectivity. The packing coverages in a jamming state for different components, connectivities through small, large and both types of disks, the behavior of electrical conductivity were analyzed. The observed complex effects were explained accounting for the formation of conductive "bridges" from small disks in pores between large disks.

description: Using algebraic tools of supersymmetric quantum mechanics we construct classes of conditionally exactly solvable potentials being the supersymmetric partners of the linear or radial harmonic oscillator. With the help of the raising and lowering operators of these harmonic oscillators and the SUSY operators we construct ladder operators for these new conditionally solvable systems. It is found that these ladder operators together with the Hamilton operator form a non-linear algebra which is of quadratic and cubic type for the SUSY partners of the linear and radial harmonic oscillator, respectively.

Integrality of the Averaged Jones Polynomial of Algebraically Split Links
Creators: name: Boden, H. U.

Subjects: subject: Quantum Algebra (math.QA)

description: X.-S. Lin and Z. Wang recently made a conjecture concerning the integrality of the Taylor coefficients of the averaged Jones polynomial of algebraically split links. This question is related to a conjectural integrality result for the Ohtsuki invariants, which are rational topological invariants of homology 3-spheres derived from the quantum invariants of Witten and Reshetikhin-Turaev. This paper presents counterexamples to the conjecture of Lin and Wang and gives a proof of a corrected statement of the conjecture. The statement is divided into two parts. The first part applies to geometrically split links and gives an integrality result which is stronger than conjectured, while the second is valid for any algebraically split link and gives a somewhat weaker statement. Both propositions are seen to be sharp by the examples given.

description: We develop a mathematically well-defined path integral formalism for general symplectic manifolds. We argue that in order to make a path integral quantization covariant under general coordinate transformations on the phase space and involve a genuine functional measure that is both finite and countably additive, the phase space manifold should be equipped with a Riemannian structure (metric). A suitable method to calculate the metric is also proposed.

description: We discuss the deformation quantization approach for the teaching of quantum mechanics. This approach has certain conceptual advantages which make its consideration worthwhile. In particular, it sheds new light on the relation between classical and quantum mechanics. We demionstrate how it can be used to solve specific problems and clarify its relation to conventional quantization and path integral techniques. We also discuss its recent applications in relativistic quantum field theory.

description: We investigate the sensitivity of Higgs(-like) inflation to higher dimensional operators in the nonminimal couplings and in the potential, both in the metric and Palatini formalisms. We find that, while inflationary predictions are relatively stable against the higher dimensional operators around the attractor point in the metric formalism, they are extremely sensitive in the Palatini one: for the latter, inflationary predictions are spoiled by $|ξ_4| \gtrsim 10^{-6}$ in the nonminimal couplings $(ξ_2 ϕ^2 + ξ_4 ϕ^4 + \cdots)R$, or by $|λ_6| \gtrsim 10^{-16}$ in the Jordan-frame potential $λ_4 ϕ^4 + λ_6 ϕ^6 + \cdots$ (both in Planck units). This extreme sensitivity results from the absence of attractor in the Palatini formalism. Our study underscores the challenge of realizing inflationary models with the nonminimal coupling in the Palatini formalism.

description: Characters and linear combinations of characters that admit a fermionic sum representation as well as a factorized form are considered for some minimal Virasoro models. As a consequence, various Rogers-Ramanujan type identities are obtained. Dilogarithm identities producing corresponding effective central charges and secondary effective central charges are derived. Several ways of constructing more general fermionic representations are discussed.

description: Eine anspruchsvolle Umweltpolitik stimuliert die heimische Nachfrage nach umweltfreundlichen Technologien und stärkt die Umweltindustrie. Die Bedeutung von Umweltpolitik als Technologietreiber und die damit verbundenen Wettbewerbsvorteile wurden in vielen Fallstudien herausgearbeitet und ist mittlerweile auch unter politischen und wirtschaftlichen Akteuren anerkannt (z. B. Jänicke 2008 mit weiteren Nachweisen). Deutschland und Euro-pa haben hier in vielen umweltpolitischen Handlungsfeldern eine gute Ausgangsposition, so z.B. in der Klimapolitik, der Förderung erneuerbarer Energien, bei der Luftreinhaltung oder der Abfallpolitik oder auch bei Standards für Automobile, Chemikalien oder für Energieeffizienz. Das Papier diskutiert die Frage, inwieweit die gezielte Unterstützung der Ausbreitung von ambitionierten Umweltpolitiken und Standards ein geeignetes Instrument darstellt, die internationale Nachfrage nach Umwelttechnologien zu erhöhen. Dazu wird die wissenschaftliche Literatur zum Thema analysiert und internationale Fallbeispiele aus der Praxis untersucht. Ein Überblick über deutsche Akteure und Aktivitäten im Bereich der internationalen Zusammenarbeit in der Umweltpolitik zeigt bisherige Schwerpunkte und mögliche Ansatzpunkte zur Weiterentwicklung von Aktivitäten. Abschließend wird ein Konzept von Umweltaußenpolitik skizziert, welches einen Rahmen darstellt für die verschiedenen umweltbezogenen Aktivitäten der Bundesregierung in der internationalen Zusammenarbeit.

description: Local autonomy is increasing as importance in the current context of the European Union. The paper aims to analyze, from such a perspective, the degree of local autonomy in European Union countries. In this regard I will propose a synthetic indicator measuring the degree of local autonomy calculated as a weighted average score based on a set of relevant quantitative and qualitative indicators of local autonomy existing in the literature whose representation in the group of indicators will be measured by a coefficient of importance. To each indicator as component of synthesis indicator will determine the field of variation and the average score obtained will be placed in classes of local autonomy defined in the assumptions made by science administration. We estimate the analysis to confirm the hypothesis that countries from European Union have differences of the degree of local autonomy between them. We consider that the paper can be a useful viewpoint in understanding the degree of local autonomy of European Union, which allows researchers to include other sources of information for researching an in a much more complex approach.
Fundamental Limits for Coherent Manipulation on Atom Chips

description: The limitations for the coherent manipulation of neutral atoms with fabricated solid state devices, so-called `atom chips', are addressed. Specifically, we examine the dominant decoherence mechanism, which is due to the magnetic noise originating from the surface of the atom chip. It is shown that the contribution of fluctuations in the chip wires at the shot noise level is not negligible. We estimate the coherence times and discuss ways to increase them. Our main conclusion is that future advances should allow for coherence times as long as one second, a few micrometers away from the surface.

description: Galaxies' stellar masses, gas-phase oxygen abundances (metallicity), and star formation rates (SFRs) obey a series of empirical correlations, most notably the mass-metallicity relation (MZR) and fundamental metallicity relation (FZR), which relates oxygen abundance to a combination of stellar mass and SFR. However, due to the difficulty of measuring oxygen abundances and SFRs in galaxies that host powerful active galactic nuclei (AGN), to date it is unknown to what extent AGN-host galaxies also follow these correlations. In this work, we apply Bayesian methods to the MaNGA integral field spectrographic (IFS) survey that allow us to measure oxygen abundances and SFRs in AGN hosts, and use these measurements to explore how the MZR and FZR differ between galaxies that do and do not host AGN. We find similar MZRs at stellar masses above $10^{10.5} \mathrm{M}_\odot$, but that at lower stellar masses AGN hosts show up to $\sim 0.2$ dex higher oxygen abundances. The offset in the FZR is significantly smaller, suggesting that the larger deviation in the MZR is a result of AGN-host galaxies having systematically lower SFRs at fixed stellar mass. However, within the AGN-host sample there is little correlation between SFR and oxygen abundance. These findings support a scenario in which an AGN can halt efficient gas accretion, which drives non-AGN host galaxies to both higher SFR and lower oxygen abundance, resulting in the galaxy evolving off the star-forming main sequence (SFMS). As a consequence, as the SFR declines for an individual system its metallicity remains mostly unchanged.
