description: Acoustic black holes are fluid dynamic analogs of general relativistic black holes, wherein the behaviour of sound waves in a moving fluid acts as an analog for scalar fields propagating in a gravitational background. Acoustic horizons possess many of the properties more normally associated with the event horizons of general relativity, up to and including Hawking radiation. They have received much attention because it would seem to be much easier to experimentally create an acoustic horizon than to create an event horizon. We wish to point out some potential difficulties (and opportunities) in actually setting up an experiment that possesses an acoustic horizon. We show that in zero-viscosity, stationary fluid flow with generic boundary conditions, the creation of an acoustic horizon is accompanied by a formally infinite ``surface gravity'', and a formally infinite Hawking flux. Only by applying a suitable non-constant external body force, and for very specific boundary conditions on the flow, can these quantities be kept finite. This problem is ameliorated in more realistic models of the fluid. For instance, adding viscosity always makes the Hawking flux finite, but greatly complicates the behaviour of the acoustic radiation --- viscosity is tantamount to explicitly breaking ``acoustic Lorentz invariance''. Thus, this issue represents both a difficulty and an opportunity --- acoustic horizons may be somewhat more difficult to form than naively envisaged, but if formed, they may be much easier to detect than one would at first suppose.

Predicting weight-loss using differential equations (PRELUDE).

description: The 3500 kcal rule(1) is a weight-loss prescription that approximates a 3500 kcal energy deficit to 1 lb of weight-loss(2). Energy intake (EI) and energy expenditure (EE) are considered independent variables and weight is assumed to decrease at a fixed rate driven purely by behaviour i.e., calorie restriction or physical activity. However, such static modelling significantly overestimates weight-loss by disregarding the presence of obligatory and adaptive perturbations in energy balance in response to underfeeding.(3). Adaptive thermogenesis refers to the underfeeding-associated decline in resting energy expenditure beyond that caused by obligatory changes in body-composition(4). Moreover, physiological mechanisms alter both EI and EE to maintain weight at a genetically determined set-point(5), resulting in less-than-expected weight-loss.
 Our research proposes a mathematical model of weight-loss that uses inputs of weight and calorie intake to convert energy deficit to weight-loss over time. EE is subdivided into resting energy expenditure (REE), physical activity energy expenditure (PAEE) and diet-induced thermogenesis (DIT). REE is modelled using predictor equations based on gender- and weight-specific FFM estimates obtained from the literature. PAEE is modelled as a product of REE and DIT is modelled as a product of calorie intake. The resulting ordinary differential equation accounts for obligatory and adaptive adjustments in all three compartments in response to underfeeding.
 Our model was tested using a large database from a commercial very-low calorie weight-loss programme with an observed mean weight-loss of 8.5%. While static modelling overestimated weight-loss by ~50% (12.5Â±3.6% vs. 8.5Â±4.5%), our refined model had a mean error of <1% (9.3Â±2.2% vs. 8.5Â±4.5%).
 Our research supports the role of mathematical modelling in clinical weight management. Reliance on simple inputs of weight and calorie intake makes our model applicable in a clinical setting.

description: The Toda lattice is a nonlinear but integrable system. Here we study the thermalization problem in one-dimensional, perturbed Toda lattices in the thermodynamic limit. We show that the thermalization time, $T_{eq}$, follows a universal law; i.e., $T_{eq}\sim ε^{-2}$, where the perturbation strength, $ε$, characterizes the nonlinear perturbations added to the Toda potential. This universal law applies generally to weak nonlinear lattices due to their equivalence to perturbed Toda systems.

description: Genus Hunyadiscus Páll-Gergely, 2016
Hunyadiscus Páll-Gergely in Páll-Gergely et al., 2016: 6.
Type species
Hunyadiscus saurini Páll-Gergely, 2016, by original designation.
Species included
Hunyadiscus andersoni (Blanford, 1869), H. saurini Páll-Gergely, 2016 and H. tigrina sp. nov.
Diagnosis
The discovery of Hunyadiscus tigrina sp. nov. extends our knowledge of the geographic distribution and shell morphology of the genus Hunyadiscus. Most importantly, however, it represents the first known record of the anatomy of this genus. Therefore, the diagnosis of Hunyadiscus is extended.
Shell dextral, body whorl bluntly keeled or bluntly shouldered; protoconch with strong spiral and radial lines (spiral lines stronger than or as strong as radial lines); apertural fold absent; parietal wall with only a single lamella, or with a lamella and some additional plicae/denticles anteriorly and/or posteriorly; palatal plicae slightly sinuate, usually horizontal. Penis short, inner penial wall with a thickened, flashy structure that is rounded in the proximal part of the penis, and divided in the middle towards the distal penial part; bursa copulatrix short with ovoid bursa; diverticulum absent.
Differential diagnosis
Hunyadiscus differs from all other plectopylid genera by the protoconch sculpture, which is characterized by both radial and spiral lines, the spirals being dominant or as strong as the radial lines. The most closely related genus is probably Naggsia Páll-Gergely & Muratov, 2016, because of the similar dextral coiling direction, the presence of spiral striation on the protoconch, the apertural fold absent or very weak and the absence of an epiphallus and because of the close geographic proximity. The two genera differ from each other in the following shell and anatomical characters: the shape of the body whorl is keeled/shouldered in Hunyadiscus and rounded in Naggsia; the protoconch bears a strong spiral striation in Hunyadiscus, and has extremely fine spiral lines in Naggsia; the inner penial wall has parallel folds in Naggsia, but a proximally rounded and distally divided, fleshy structure in Hunyadiscus; the diverticulum is well-developed in Naggsia, and absent in Hunyadiscus.
Distribution
Northern Laos, northern Thailand, southern Kachin State of Myanmar, and the bordering Chinese region.
Remarks
Table 1 summarizes the key characters of species of Hunyadiscus.

description: We derive the two-dimensional equation of state for a bosonic system of ultracold atoms interacting with a finite-range effective interaction. Within a functional integration approach, we employ an hydrodynamic parametrization of the bosonic field to calculate the superfluid equations of motion and the zero-temperature pressure. The ultraviolet divergences, naturally arising from the finite-range interaction, are regularized with an improved dimensional regularization technique.

description: This study aimed to reduce the bitterness and astringency properties of autumn green tea using different yellowing and drying treatments. The results showed that as the yellowing temperature increased, the contents of tea polyphenols, gallated catechins, flavonol glycosides, and bitter amino acids decreased, while the content of soluble sugar and flavonols increased. The tea sample (YEL35 °C) subjected to yellowing treatment at 35 °C exhibited weak bitterness and astringency intensities and a relatively low content of flavonol glycosides. As the drying temperature increased, the content of gallated catechins decreased. In addition, the tea sample (DRY75 °C) subjected to drying treatment at 75 °C exhibited weak bitterness and astringency intensities, the highest contents of umami amino acids and Thea, and a relatively low content of gallated catechins. Multivariate statistical analysis revealed that vitexin-2-O-rhamnoside, pferol-3-O-rutinoside, myricetin-3-O-galactoside, and quercetin-3-O-glucoside played an important role in the astringency property of the tea. In addition, Asn, Thr, Pro, and Met were positively correlated with umami. Hence, the quality of autumn green tea was improved under optimal yellowing and drying temperatures of 35 and 75 °C, respectively.

description: The N=4 gauged SU(2)$\times$SU(1,1) supergravity in four-dimensional Euclidean space is obtained via a consistent dimensional reduction of the N=1, D=10 supergravity on $S^3\times AdS_3$. The dilaton potential in the theory is proportional to the difference of the two gauge coupling constants, which is due to the opposite signs of the curvatures of $S^3$ and $AdS_3$. As a result, the potential can be positive, negative, or zero-depending on the values of the constants. A consistent reduction of the fermion supersymmetry transformations is performed at the linearized level, and special attention is paid to the Euclidean Majorana condition. A further reduction of the D=4 theory is considered to the static, purely magnetic sector, where the vacuum solutions are studied. The Bogomol'nyi equations are derived and their essentially non-Abelian monopole-type and sphaleron-type solutions are presented. Any solution in the theory can be uplifted to become a vacuum of string or M-theory.

description: Considerable excitement has been caused recently by the discovery that the binary boride system with stoichiometry MgB2 is superconducting at the remarkably high temperature of 39 K (1). This potentially opens the way to even higher Tc values in a new family of superconductors with unexpectedly simple composition and structure. The simplicity in the electronic and crystal structures could allow the understanding of the physics of high-Tc superconductivity without the presence of the multitude of complicated features, associated with the cuprates. Synchrotron X-ray diffraction was used to measure the isothermal compressibility of MgB2, revealing a stiff tightly-packed incompressible solid with only moderate bonding anisotropy between intra- and inter-layer directions. These results, combined with the pressure evolution of the superconducting transition temperature, Tc establish its relation to the B and Mg bonding distances over a broad range of values.

The exact energy spectrum and the n-point hole correlations are considered with the help of the Jordan-Wigner fermionization and the inter-particle distribution function method. Although the Hamiltonian has no explicit translational symmetry, the translational invariance is recovered after long time due to the diffusion. We see the scaling relations for the concentration and the two-point function in finite size analysis.

Since the fall of Muammar Gaddafi’s regime in 2011, Libya has faced political fragmentation, economic instability, and security challenges, while traditional attempts at comprehensive peace agreements have struggled to address the country’s deep divisions.

This paper advocates for an alternative approach: incremental agreements, a strategy that prioritises step-by-step solutions to build trust, cooperation, and long-term stability. By breaking down major disputes into smaller, manageable agreements, Libya can create a foundation for sustainable peace, reducing the risks associated with large-scale political settlements while allowing for adaptable and locally driven solutions.
Conformal positive mass theorems

Publisher: name: arXiv
Year: 2000
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We show the following two extensions of the standard positive mass theorem (one for either sign): Let (N,g) and (N,g') be asymptotically flat Riemannian 3-manifolds with compact interior and finite mass, such that g and g' are twice Hoelder differentiable and related via the conformal rescaling g' = (phi^4).g, with a twice Hoelder differentiable function phi>0. Assume further that the corresponding Ricci scalars satisfy either R + (phi^4).R' >= 0 or R - (phi^4).R' >= 0. Then the corresponding masses satisfy m + m' >= 0 or m - m' >= 0, respectively. Moreover, in the case of the minus signs, equality holds iff g and g' are isometric, whereas for the plus signs equality holds iff both (N,g) and (N,g') are flat Euclidean spaces. While the proof of the case with the minus signs is rather obvious, the case with the plus signs requires a subtle extension of Witten's proof of the standard positive mass theorem. The idea for this extension is due to Masood-ul-Alam who, in the course of an application, proved the rigidity part m + m' = 0 of this theorem, for a special conformal factor. We observe that Masood-ul-Alam's method extends to the general situation.

description: The goal of this work is to develop a meeting transcription system that can recognize speech even when utterances of different speakers are overlapped. While speech overlaps have been regarded as a major obstacle in accurately transcribing meetings, a traditional beamformer with a single output has been exclusively used because previously proposed speech separation techniques have critical constraints for application to real meetings. This paper proposes a new signal processing module, called an unmixing transducer, and describes its implementation using a windowed BLSTM. The unmixing transducer has a fixed number, say J, of output channels, where J may be different from the number of meeting attendees, and transforms an input multi-channel acoustic signal into J time-synchronous audio streams. Each utterance in the meeting is separated and emitted from one of the output channels. Then, each output signal can be simply fed to a speech recognition back-end for segmentation and transcription. Our meeting transcription system using the unmixing transducer outperforms a system based on a state-of-the-art neural mask-based beamformer by 10.8%. Significant improvements are observed in overlapped segments. To the best of our knowledge, this is the first report that applies overlapped speech recognition to unconstrained real meeting audio.

description: We observe dark and bright intrinsic localized modes (ILMs) or discrete breathers (DB) experimentally and numerically in a diatomic-like electrical lattice. The generation of dark ILMs by driving a dissipative lattice with spatially-homogenous amplitude is, to our knowledge, unprecedented. In addition, the experimental manifestation of bright breathers within the bandgap is also novel in this system. In experimental measurements the dark modes appear just below the bottom of the top branch in frequency. As the frequency is then lowered further into the band-gap, the dark DBs persist, until the nonlinear localization pattern reverses and bright DBs appear on top of the finite background. Deep into the bandgap, only a single bright structure survives in a lattice of 32 nodes. The vicinity of the bottom band also features bright and dark self-localized excitations. These results pave the way for a more systematic study of dark breathers and their bifurcations in diatomic-like chains.

description: Generative adversarial networks have been able to generate striking results in various domains. This generation capability can be general while the networks gain deep understanding regarding the data distribution. In many domains, this data distribution consists of anomalies and normal data, with the anomalies commonly occurring relatively less, creating datasets that are imbalanced. The capabilities that generative adversarial networks offer can be leveraged to examine these anomalies and help alleviate the challenge that imbalanced datasets propose via creating synthetic anomalies. This anomaly generation can be specifically beneficial in domains that have costly data creation processes as well as inherently imbalanced datasets. One of the domains that fits this description is the host-based intrusion detection domain. In this work, ADFA-LD dataset is chosen as the dataset of interest containing system calls of small foot-print next generation attacks. The data is first converted into images, and then a Cycle-GAN is used to create images of anomalous data from images of normal data. The generated data is combined with the original dataset and is used to train a model to detect anomalies. By doing so, it is shown that the classification results are improved, with the AUC rising from 0.55 to 0.71, and the anomaly detection rate rising from 17.07% to 80.49%. The results are also compared to SMOTE, showing the potential presented by generative adversarial networks in anomaly generation.

description: The influence of electron-electron (e-e) interactions on the transmission through a quantum dot is investigated numerically for the Coulomb blockade regime. For vanishing magnetic fields, the conductance peak height statistics is found to be independent of the interactions strength. It is identical to the statistics predicted by constant interaction single electron random matrix theory and agrees well with recent experiments. However, in contrast to these random matrix theories, our calculations reproduces the reduced sensitivity to magnetic flux observed in many experiments. The relevant physics is traced to the short range Coulomb correlations providing thus a unified explanation for the transmission statistics as well as for the large conductance peak spacing fluctuations observed in other experiments.

description: We study quantum radiation generated by an accelerated motion of a small body with a refractive index n which differes slightly from 1. To simplify calculations we consider a model with a scalar massless field. We use the perturbation expansion in a small parameter n-1 to obtain a correction to the vacuum Hadamard function for a uniformly accelerated motion of the body. We obtain the vacuum expectation for the energy density flux in the wave zone and discuss its properties.

The century of the incomplete revolution: searching for general relativistic quantum field theory

description: In fundamental physics, this has been the century of quantum mechanics and general relativity. It has also been the century of the long search for a conceptual framework capable of embracing the astonishing features of the world that have been revealed by these two ``first pieces of a conceptual revolution''. I discuss the general requirements on the mathematics and some specific developments towards the construction of such a framework. Examples of covariant constructions of (simple) generally relativistic quantum field theories have been obtained as topological quantum field theories, in nonperturbative zero-dimensional string theory and its higher dimensional generalizations, and as spin foam models. A canonical construction of a general relativistic quantum field theory is provided by loop quantum gravity. Remarkably, all these diverse approaches have turn out to be related, suggesting an intriguing general picture of general relativistic quantum physics.

Ruling out $\sim 100-300$ GeV thermal relic annihilating dark matter by radio observation of the Andromeda galaxy

description: In the past few years, some studies claimed that annihilating dark matter with mass $\sim 10-100$ GeV can explain the GeV gamma-ray excess in our Galaxy. However, recent analyses of the Fermi-LAT and radio observational data rule out the possibility of the thermal relic annihilating dark matter with mass $m \le 100$ GeV for some popular annihilation channels. By using the new observed radio data of the Andromeda galaxy, we rule out the existence of $\sim 100-300$ GeV thermal relic annihilating dark matter for ten annihilation channels. The lower limits of annihilating dark matter mass are improved to larger than 330 GeV for the most conservative case, which is a few times larger than the current best constraints. Moreover, these limits strongly disfavor the benchmark model of weakly interacting massive particle (WIMP) produced through the thermal freeze-out mechanism.

Ultra-thin carbon nanotube networks - a novel platform for cardiac cell culture, electrical stimulation, and drug discovery

description: Cardiovascular disease (CVD) is the number one global cause of death, accounting for approximately 31% of all deaths annually (1). Despite CVDâ€™s continued burden on healthcare services, between 1990 and 2012 there was a general decline in the amount of research into CVDs (2). While research into CVDs is starting to increase again, basic research â€“ interrogating the mechanisms behind CVDs â€“ has shown the least growth (3). Part of the reason for this turbulent trend in research efforts is that cardiac cell types are notoriously challenging to culture ex vivo. Carbon nanotubes (CNTs), in combination with tissue engineering techniques, are uniquely suited to providing new reliable and dynamic experimental platforms for CVD research due to their versatility in biomaterial formulations, structural similarity to cardiac extracellular proteins and, most importantly, their electrical conductivity (4â€“6). Research thus far has created electrically conductive CNT scaffolds for cardiomyocytes (CMs), for use as a platform for cardiac disease modelling and pharmaceutical research. Here, a tissue culture scaffold consisting of thin, isotropic networks of CNTs was developed, that possesses optical transparency, resistivity in the MÎ© range, nanoscale surface topography, and biocompatibility based on wettability. CMs grown on CNTs showed significantly enhanced contractile function, and expression of cardiac specific, contractile and adherence proteins. Further studies will look to investigate the mechanisms behind the enhanced contractile function of CMs on CNTs and the efficacy of paced electrical stimulation in eliciting arrhythmic disease phenotypes to provide proof-of-concept for this platform as a disease modelling system for pharmaceutical research and development into new therapies for CVDs.
Stable Configurations Of Charged Sedimenting Particles

description: The qualitative behavior of charged particles in a vacuum is given by Earnshaw's Theorem which states that there is no steady configuration of charged particles in a vacuum which is asymptotically stable to perturbations. In a viscous fluid, examples of stationary configurations of sedimenting uncharged particles are known, but they are unstable or neutrally stable - they are not attractors. In this paper, it is shown by example that two charged particles settling in a fluid may have a configuration which is asymptotically stable to perturbations, for a wide range of charges, radii and densities. The existence of such "bound states" is essential from a fundamental point of view and it can be significant for dilute charged particulate systems in various biological, medical and industrial contexts.

Inverse versus Normal NiAs Structure as High-Pressure Phase of FeO and MnO

description: The high-pressure phases of FeO and MnO were studied by the first principles calculations. The present theoretical study predicts that the high-pressure phase of MnO is a metallic normal B8 structure (nB8), while that of FeO should take the inverse B8 structure (iB8). The novel feature of the unique high-pressure phase of stoichiometric FeO is that the system should be a band insulator in the ordered antiferromagnetic (AF) state and that the existence of a band gap leads to special stability of the phase. The observed metallicity of the high-pressure and high-temperature phase of FeO may be caused by the loss of AF order and also by the itinerant carriers created by non-stoichiometry. Analysis of x-ray diffraction experiments provides a further support to the present theoretical prediction for both FeO and MnO. Strong stability of the high-pressure phase of FeO will imply possible important roles in Earth's core.

HEIs participations and mobility in the European Framework Programmes
Creators: name: Mantegazzini, Barbara Antonioli
name: Lepori, Benedetto

Year: 2019
Subjects: Framework Progammes, Participation to FPs, Higher Education Institutions, mobility analysis

description: Based on an extended version of the European Tertiary Education Register database (ETER; https://www.eter-project.com), we develop a quantitative analysis of changes in HEIs participation to EU-FPs for the period 2008 - 2015. From a methodological point of view, we firstly cluster the institutions according to their level of participation and then we describe and investigate on the dynamic of their participation over time, focusing on the mobility of the lower bound group of HEIs, i.e. the institutions with a small, even null, number of participation. The idea is to analyse the mobility of institutions clustering them as potential entrant, leavers to the participant group and speculating on possible rationales of these movements. Results represent the basis for the formulation of several policy questions. In particular, we are interested in analyse the potential role of national policies in two different dimensions: a) the way they affect the structure and the volume of resources of the HEIs; b) how they (directly) affect the participation, for example through national support measures.
