We identify a dimensionless parameter $Δ\sim(δN)^{(d+1)/d}/V$ and a \textrm{universal} value $\Deltac=\Deltac(d)$, and show that a droplet of the dense phase occurs whenever $Δ>\Deltac$, while, for $Δ

description: Grids of stellar models are useful tools to derive the properties of stellar clusters, in particular young clusters hosting massive stars, and to provide information on the star formation process in various mass ranges. Because of their short evolutionary timescale, massive stars end their life while their low-mass siblings are still on the pre-main sequence (pre-MS) phase. Thus the study of young clusters requires consistent consideration of all the phases of stellar evolution. But despite the large number of grids that are available in the literature, a grid accounting for the evolution from the pre-MS accretion phase to the post-MS phase in the whole stellar mass range is still lacking. We build a grid of stellar models at solar metallicity with masses from 0.8 $M_\odot$ to 120 $M_\odot$, including pre-MS phase with accretion. We use the {\sc genec} code to run stellar models on this mass range. The accretion law is chosen to match the observations of pre-MS objects on the Hertzsprung-Russell diagram. We describe the evolutionary tracks and isochrones of our models. The grid is connected to previous MS and post-MS grids computed with the same numerical method and physical assumptions, which provides the widest grid in mass and age to date. Numerical tables of our models and corresponding isochrones are available online.

description: Hematopoietic stem cells facilitate lifelong production of a diverse repertoire of functional mature blood cells. They are a critical biological reservoir that enable organisms to endure physiological challenges such as inflammation, disease, and age. The functional maintenance of hematopoietic stem cells depends not only on intrinsic cell pathways, but also on extrinsic cues that guide core behaviors like homing and self-renewal. Careful study of these extrinsic regulatory networks can deepen our appreciation of fundamental stem cell biology and motivate therapeutic approaches to treat hematologic disease. Here I show how derangement of the bone marrow regulatory environment perturbs normal hematopoiesis, and demonstrate the dependence of hematopoietic stem cells on a circulating endocrine factor.
Corrections to scaling in the 2D phi^4 model: Monte Carlo results and some related problems

Publisher: name: arXiv
Year: 2024
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Monte Carlo (MC) simulations have been performed to refine the estimation of the correction-to-scaling exponent $ω$ in the 2D $φ^4$ model, which belongs to one of the most fundamental universality classes. If corrections have the form $\propto L^{-ω}$, then we find $ω=1.546(30)$ and $ω=1.509(14)$ as the best estimates. These are obtained from the finite-size scaling of the susceptibility data in the range of linear lattice sizes $L \in [128,2048]$ at the critical value of the Binder cumulant and from the scaling of the corresponding pseudocritical couplings within $L \in [64,2048]$. These values agree with several other MC estimates at the assumption of the power-law corrections and are comparable with the known results of the $ε$-expansion. In addition, we have tested the consistency with the scaling corrections of the form $\propto L^{-4/3}$, $\propto L^{-4/3} \ln L$ and $\propto L^{-4/3} /\ln L$, which might be expected from some considerations of the renormalization group and Coulomb gas model. The latter option is consistent with our MC data. Our MC results served as a basis for a critical reconsideration of some earlier theoretical conjectures and scaling assumptions. In particular, we have corrected and refined our previous analysis by grouping Feynman diagrams. The renewed analysis gives $ω\approx 4-d-2 η$ as some approximation for spatial dimensions $d<4$, or $ω\approx 1.5$ in two dimensions.

description: We perform fully general-relativistic simulations of binary strange star mergers considering two different approaches for thermal effects. The first uses a cold equation of state (EOS) derived from a modified version of the MIT bag model which is then supplemented by a $Γ$-law correction. The second approach employs a microphysical description of the finite-temperature effects. We describe results obtained with the two treatments, highlighting the influence of thermal effects. We find that the postmerger dynamics differs significantly in the two cases, leading to quantitative differences in the postmerger gravitational-wave spectrum and ejecta mass. The peak frequency of the postmerger gravitational-wave emission is consistent with the established quasi-universal relations for binary neutron star mergers and as a result, our simulations cannot distinguish between mergers of neutron stars and those of strange stars. Our models with realistic treatment of finite-temperature effects produce a significant amount of ejecta $\gtrsim 0.02\ M_{\odot}$. The resulting flux of strangelets near the Earth, computed assuming that all neutron star mergers are in fact strange-stars mergers and that the binary considered here is representative, is in tension with experimental upper limits. As such, our results tentatively disfavor a scenario in which strange-quark matter is the lowest energy state of matter.

Mode fluctuations as fingerprint of chaotic and non-chaotic systems

description: The mode-fluctuation distribution $P(W)$ is studied for chaotic as well as for non-chaotic quantum billiards. This statistic is discussed in the broader framework of the $E(k,L)$ functions being the probability of finding $k$ energy levels in a randomly chosen interval of length $L$, and the distribution of $n(L)$, where $n(L)$ is the number of levels in such an interval, and their cumulants $c_k(L)$. It is demonstrated that the cumulants provide a possible measure for the distinction between chaotic and non-chaotic systems. The vanishing of the normalized cumulants $C_k$, $k\geq 3$, implies a Gaussian behaviour of $P(W)$, which is realized in the case of chaotic systems, whereas non-chaotic systems display non-vanishing values for these cumulants leading to a non-Gaussian behaviour of $P(W)$. For some integrable systems there exist rigorous proofs of the non-Gaussian behaviour which are also discussed. Our numerical results and the rigorous results for integrable systems suggest that a clear fingerprint of chaotic systems is provided by a Gaussian distribution of the mode-fluctuation distribution $P(W)$.

Dazu werden die im Focus-Ansatz [BS01] eingeführten Ströme im Theorembeweiser Isabelle [NPW02] in komfortabler Weise so umgesetzt, dass sowohl verteilte Komponenten als auch Protokolle zwischen Komponenten einfach und elegant definiert und ihre Eigenschaften untersucht werden können. Zur Verfügung stehen Techniken zur Definition von Liveness-und Fairness-Eigenschaften, schnittstellenbasierte Komposition und Verfeinerungstechniken, die miteinander kompatibel sind. Die Focus-Theorie basiert im Wesentlichen auf der Formalisierung von Kommunikationshistorien und von Komponenten als mathematische Funktion, die Eingabe- und Ausgabehistorien abbildet. Das hier vorgestellte Modell für potentiell unendliche Ströme nutzt einen grundlegenden neuen Datentypkonstruktor fstream, der zwar auf HOLCF beruht, in dessen Umgang aber der Anwender nicht explizit auf HOLCF angewiesen ist. Dadurch ist HOLCF vor dem Anwender verborgen.

description: We characterize the tempered part of the automorphic Langlands category D-mod(Bun_G) using the geometry of the big cell in the affine Grassmannian. We deduce that, for $G$ non-abelian, tempered D-modules have no de Rham cohomology with compact supports. The latter fact boils down to a concrete statement, which we prove using the Ran space and some explicit t-structure estimates: for $G$ non-abelian and $Σ$ a smooth affine curve, the Borel-Moore homology of the indscheme $Maps(Σ,G)$ vanishes.

description: Coherent population trapping (CPT) is a multi-level quantum coherence phenomenon of promising applications in atomic clocks and magnetometers. Particularly, multi-pulse CPT-Ramsey interferometry is a powerful tool for improving the performance of CPT atomic clocks. Most studies on multi-pulse CPT-Ramsey interferometry consider periodic pulse sequence and time-independent detuning. However, to further improve the accuracy and precision, one may modify the spectrum symmetry which involves pulse sequence with time-dependent detuning or phase shift. Here, we theoretically analyze the multi-pulse CPT-Ramsey interferometry under arbitrary pulse sequences of time-dependent detuning and obtain a general analytical formula. Using our formula, we analyze the popular CPT-Ramsey interferometry schemes such as two-pulse symmetric and antisymmetric spectroscopy, and multi-pulse symmetric and antisymmetric spectroscopy. Moreover, we quantitatively obtain the influences of pulse width, pulse period, pulse number, and Rabi frequency under periodic pulses. Our theoretical results can guide the experimental design to improve the performance of atomic clocks via multi-pulse CPT-Ramsey interferometry.

description: As an homage to Quantum Energy Teleportation, we generalize the idea to arbitrary physical observables, not limited to energy, and prove a rigorous upper bound on the activated ("teleported") quantity. The essence of this protocol is a quantum feedback control with respect to the entangled ground state of a quantum many-body system. To demonstrate the concept, we explore a (1+1)-dimensional chiral Dirac system and execute the protocol for the electric current and charge. One of the most significant results is the creation of long-range correlations across the system after applying control operations only to one local site. Consequently but surprisingly, the induced charge susceptibility fully reconstructs the phase diagram, despite the model initially having no charge. Moreover, we find an activation of novel chiral dynamics induced by feedback control operations, which can be experimentally confirmed using trapped ions and neutral atoms.

description: In this article, we establish in a rigorous mathematical way that Koba-Nielsen amplitudes defined on any local field of characteristic zero are bona fide integrals that admit meromorphic continuations in the kinematic parameters. Our approach allows us to study in a uniform way open and closed Koba-Nielsen amplitudes over arbitrary local fields of characteristic zero. In the regularization process we use techniques of local zeta functions and embedded resolution of singularities. As an application we present the regularization of p-adic open string amplitudes with Chan-Paton factors and constant B-field. Finally, all the local zeta functions studied here are partition functions of certain 1D log-Coulomb gases, which shows an interesting connection between Koba-Nielsen amplitudes and statistical mechanics.

description: Recent advances in unsupervised learning have highlighted the possibility of learning to reconstruct signals from noisy and incomplete linear measurements alone. These methods play a key role in medical and scientific imaging and sensing, where ground truth data is often scarce or difficult to obtain. However, in practice, measurements are not only noisy and incomplete but also quantized. Here we explore the extreme case of learning from binary observations and provide necessary and sufficient conditions on the number of measurements required for identifying a set of signals from incomplete binary data. Our results are complementary to existing bounds on signal recovery from binary measurements. Furthermore, we introduce a novel self-supervised learning approach, which we name SSBM, that only requires binary data for training. We demonstrate in a series of experiments with real datasets that SSBM performs on par with supervised learning and outperforms sparse reconstruction methods with a fixed wavelet basis by a large margin.

Parameterised Counting in Logspace

description: In this paper, we introduce a new framework for parameterised counting in logspace, inspired by the parameterised space bounded models developed by Elberfeld, Stockhusen and Tantau (IPEC 2013, Algorithmica 2015). They defined the operators paraW and paraBeta for parameterised space complexity classes by allowing bounded nondeterminism with multiple-read and read-once access, respectively. Using these operators, they characterised the parameterised complexity of natural problems on graphs. In the spirit of the operators paraW and paraBeta by Stockhusen and Tantau, we introduce variants based on tail-nondeterminism, paraW[1] and paraBeta-Tail. Then, we consider counting versions of all four operators applied to logspace and obtain several natural complete problems for the resulting classes: counting of paths in digraphs, counting first-order models for formulas, and counting graph homomorphisms. Furthermore, we show that the complexity of a parameterised variant of the determinant function for (0,1)-matrices is #paraBeta-Tail-L-hard and can be written as the difference of two functions in #paraBetaTail-L. For example, we show that the closure of #paraBetaTail-L under parameterised logspace parsimonious reductions coincides with #paraBeta-L, that is, modulo parameterised reductions, tail-nondeterminism with read-once access is the same as read-once nondeterminism. We show that all introduced classes are closed under addition and multiplication, and those without tail-nondeterminism are closed under parameterised logspace parsimonious reductions. Finally, we underline the significance of this topic by providing a promising outlook showing several open problems and options for further directions of research.

description: Assuming the validity of random matrices for describing the statistics of a closed chaotic quantum system, we study analytically some statistical properties of the S-matrix characterizing scattering in its open counterpart. In the first part of the paper we attempt to expose systematically ideas underlying the so-called stochastic (Heidelberg) approach to chaotic quantum scattering. Then we concentrate on systems with broken time-reversal invariance coupled to continua via M open channels. By using the supersymmetry method we derive: (i) an explicit expression for the density of S-matrix poles (resonances) in the complex energy plane (ii) an explicit expression for the parametric correlation function of densities of eigenphases of the S-matrix. We use it to find the distribution of derivatives of these eigenphases with respect to the energy ("partial delay times" ) as well as with respect to an arbitrary external parameter.

description: The large language model called ChatGPT has drawn extensively attention because of its human-like expression and reasoning abilities. In this study, we investigate the feasibility of using ChatGPT in experiments on using ChatGPT to translate radiology reports into plain language for patients and healthcare providers so that they are educated for improved healthcare. Radiology reports from 62 low-dose chest CT lung cancer screening scans and 76 brain MRI metastases screening scans were collected in the first half of February for this study. According to the evaluation by radiologists, ChatGPT can successfully translate radiology reports into plain language with an average score of 4.27 in the five-point system with 0.08 places of information missing and 0.07 places of misinformation. In terms of the suggestions provided by ChatGPT, they are general relevant such as keeping following-up with doctors and closely monitoring any symptoms, and for about 37% of 138 cases in total ChatGPT offers specific suggestions based on findings in the report. ChatGPT also presents some randomness in its responses with occasionally over-simplified or neglected information, which can be mitigated using a more detailed prompt. Furthermore, ChatGPT results are compared with a newly released large model GPT-4, showing that GPT-4 can significantly improve the quality of translated reports. Our results show that it is feasible to utilize large language models in clinical education, and further efforts are needed to address limitations and maximize their potential.

Subjects: subject: Volaemia, Hypovolaemic shock, fluid responsiveness, echocardiography.

description: In humans, echocardiography is the standard of care in patients in shock, helping intensivists to characterize the haemodynamic disorder, to select a therapeutic approach and to monitor the response to treatment. In veterinary medicine the use of ultrasonography is limited to the assessment of the caudal vena cava (CVC), as a method of estimating volaemia. The current study aimed to explore whether echocardiographic measurements can be useful in the diagnosis and monitoring of the response to treatment in cases of suspected hypovolaemia. The study cohort comprised of eighteen dogs presented to an out of hours service for suspicion of hypovolaemia, and the control cohort consisted of nineteen dogs presented for echocardiography that were diagnosed as not having substantial cardiac disease. Data from the physical exam (mucous membrane colour, heart rate, pulse quality, capillary refill time), systolic blood pressure (SBP), and laboratory findings (lactate concentration (LAC), total protein (TP), packed cell volume (PCV)) were recorded for the study cohort and used to decide if the patients were suspected to be hypovolaemic. Dogs from both cohorts were scanned conscious in right lateral recumbency. Ultrasonographic measurements comprised: maximal diameter of the CVC (CVCmax), CVC collapsibility index (CVC CI), CVC to aorta ratio (CVC/Ao), maximal dimension of left atrium to aorta ratio (LAmajor/Ao), left ventricular internal diameter in diastole normalized for bodyweight by allometric scaling (LVIDdN), end diastolic ventricular volume index (EDVI), and stroke volume (SV) obtained from the aortic velocity- time integral. All the physical exam variables, laboratory tests and ultrasonographic measurements were measured again in the study cohort after the administration of intravenous fluid therapy. The median time to perform the ultrasonographic protocol was 4 (3-4) minutes. The best discriminator to differentiate between cases and controls was the EDVI (P=0.047), however the specificity (42%) and sensitivity (53%) were very low. The heart rate, capillary refill time, TP, PCV, CVCmax, CVC/Ao, LAmajor/Ao, LVIDdN, EDVI and SV were significantly different (P≤0.05) after treatment. This study shows that a simplified echocardiographic protocol, that can be performed in a limited time can provide useful information about the volume status of the conscious, spontaneously breathing, clinically ill dog and can be helpful in monitoring the response to treatment.

description: We demonstrate for a generic pseudointegrable billiard that the number of periodic orbit families with length less than $l$ increases as $πb_0l^2/\langle a(l) \rangle$, where $b_0$ is a constant and $\langle a(l) \rangle$ is the average area occupied by these families. We also find that $\langle a(l) \rangle$ increases with $l$ before saturating. Finally, we show that periodic orbits provide a good estimate of spectral correlations in the corresponding quantum spectrum and thus conclude that diffraction effects are not as significant in such studies.

F-virtual Abelian Varieties and Rallis Inner Product Formula

Subjects: subject: Mathematics

description: This thesis consists of two topics. First we study F-virtual Abelian varieties of GL2-type where F is a number field. We show the relation between these Abelian varieties and those defined over F. We compare their l-adic representations and study the modularity of F-virtual Abelian varieties of GL2-type. Then we construct their moduli spaces and in the case where the moduli space is a surface we give criteria when it is of general type. We also give two examples of surfaces that are rational and one that is neither rational nor of general type.  Second we prove a crucial case of Siegel-Weil formula for orthogonal groups and metaplectic groups. With this we can compute the pairing of theta functions and show in this case that it is related to the central value of Langlands L-function. This new case of Rallis inner product formula enables us to relate nonvanishing of L-value to the nonvanishing of theta lifting.

description: Integrin recycling has been generally assumed to be important for cell migration but the trafficking pathways and the molecules regulating integrin trafficking remain poorly characterized. Furthermore, little is known about the activation status of endocytosed integrins and how it affects the recycling of these receptors. It is likely that FA-engaged integrins will follow different trafficking pathways than bulk integrins and here I sought to study the endocytic fate of this particular integrin pool using the MT-induced FA disassembly assay. I found that integrins previously resident at FAs travel through different Rab compartments after FA disassembly and that their return to the plasma membrane is Rab11- and Src-dependent. Strikingly, I unveiled new functions for FAK and Src family kinases in this process by showing that these kinases are critical to keep integrins active during endocytic trafficking. This finding is unprecedented since it was not known whether endocytosed integrins were kept active during their trafficking. Interestingly, reassembly of FAs from endocytosed integrin occurred preferentially at the leading edge of migrating cells suggesting that integrins are trafficked in a polarized fashion. Furthermore, the recycling of integrins from the Rab11-positive compartment to the plasma membrane is a long-range transport implying the existence of a MT motor committed to this task. Consistently, I identified that a kinesin-II motor, Kif3AC, is engaged in this process. My work establishes a FAK- and Src family kinases-based mechanism for integrin "adhesion memory" during endocytic trafficking and identifies a direct link between FA disassembly and reassembly through an endocytic recycling pathway involving Rab5 and Rab11 and a kinesin-II family member.

Communication Cost for Non-Markovianity of Tripartite Quantum States: A Resource Theoretic Approach

description: To quantify non-Markovianity of tripartite quantum states from an operational viewpoint, we introduce a class $Ω^*$ of operations performed by three distant parties. A tripartite quantum state is a free state under $Ω^*$ if and only if it is a quantum Markov chain. We introduce a function of tripartite quantum states that we call the non-Markovianity of formation, and prove that it is a faithful measure of non-Markovianity, which is continuous and monotonically nonincreasing under a subclass $Ω$ of $Ω^*$. We consider a task in which the three parties generate a non-Markov state from scratch by operations in $Ω$, assisted with quantum communication from the third party to the others, which does not belong to $Ω$. We prove that the minimum cost of quantum communication required therein is asymptotically equal to the regularized non-Markovianity of formation. Based on this result, we provide a direct operational meaning to a measure of bipartite entanglement called the c-squashed entanglement.

description: We discuss several applications of the recently proposed combined nonlinear-condensation transformation (CNCT) for the evaluation of slowly convergent, nonalternating series. These include certain statistical distributions which are of importance in linguistics, statistical-mechanics theory, and biophysics (statistical analysis of DNA sequences). We also discuss applications of the transformation in experimental mathematics, and we briefly expand on further applications in theoretical physics. Finally, we discuss a related Mathematica program for the computation of Lerch's transcendent.

description: Bilayer graphene (BLG) was recently shown to host a band-inverted phase with unconventional topology emerging from the Ising-type spin--orbit interaction (SOI) induced by the proximity of transition metal dichalcogenides with large intrinsic SOI. Here, we report the stabilization of this band-inverted phase in BLG symmetrically encapsulated in tungsten-diselenide (WSe$_2$) via hydrostatic pressure. Our observations from low temperature transport measurements are consistent with a single particle model with induced Ising SOI of opposite sign on the two graphene layers. To confirm the strengthening of the inverted phase, we present thermal activation measurements and show that the SOI-induced band gap increases by more than 100% due to the applied pressure. Finally, the investigation of Landau level spectra reveals the dependence of the level-crossings on the applied magnetic field, which further confirms the enhancement of SOI with pressure.

description: Manipulating the polarization of light is highly desired for versatile applications ranging from super resolution, optical trapping, to particle acceleration. The enormous freedom in metasurface design motivates the implementation of polarization control in ultrathin and compact optical systems. However, the majority of proposed strategies based on metasurfaces have been demonstrated only a spatially homogeneous polarization generation, while less attention has been devoted to spatially variant inhomogeneous vector beams. Here, we demonstrate a novel method for generating arbitrary radial and azimuthal polarization beams with high efficiencies of up to 80% by utilizing transmission-type dielectric metasurfaces. Polarization conversion metasurfaces are suitable candidates for the implementation of polarization encryption, which we demonstrate by encoding a hidden image into the spatial polarization distribution. In addition, we show that the image pattern can be modified by appropriate polarization selection of the transmitted light. Such a method may provide a practical technique for a variety of applications such as imaging, encryption and anti-counterfeiting.

description: The kinetic Sunyaev Zel'dovich (kSZ) effect, cosmic microwave background (CMB) temperature anisotropies induced by scattering of CMB photons from free electrons, forms the dominant blackbody component of the CMB on small angular scales. Future CMB experiments on the resolution/sensitivity frontier will measure the kSZ effect with high significance. Through the cross-correlation with tracers of structure, it will be possible to reconstruct the remote CMB dipole field (e.g. the CMB dipole observed at different locations in the Universe) using the technique of kSZ tomography. In this paper, we derive a quadratic estimator for the remote dipole field using the Cosmic Infrared Background (CIB) as a tracer of structure. We forecast the ability of current and next-generation measurements of the CMB and CIB to perform kSZ tomography. The total signal-to-noise of the reconstruction is order unity for current datasets, and can improve by a factor of up to $10^3$ for future datasets, based on statistical error only. The CIB-based reconstruction is highly correlated with a galaxy survey-based reconstruction of the remote dipole field, which can be exploited to improve constraints on cosmological parameters and models for the CIB and distribution of baryons.

Pictures of time beneath : science, landscape, heritage and the uses of the deep past in Australia, 1830-2003

description: This thesis explores ideas about the deep past in Australia in the context of contemporary notions of geological heritage, cultural property, cultural identity and antiquity. Moving between disciplines, localities, stories and timescales it examines the complexities of changing intellectual agenda. But it does not pretend to present a complete history of the earth sciences in Australia. Rather it brings together an array of related themes, places, and stories, that knit into a narrative about the construction and interpretation of signs of age in Australian landscapes. Taking as its starting point the discovery by European settlers in 1830 of the Wellington Caves megafaunal fossils, which first suggested a long chronology for Australian vertebrate fauna, this work considers 'ordinary time' and 'deep time', geological heritage, the appropriation and celebration of deep time by settler Australians, and the naturalisation of narrative and sequence in geological writing. The body of the thesis involves discussion of three landscapes which have been celebrated for the deep pasts revealed in their sediments, landforms and material remains: Hallett Cove and Lake Callabonna in South Australia and the Willandra Lakes in New South Wales. Each of these is regarded as more or less canonical in the respective histories of Australian geology, vertebrate palaeontology and archaeology, but each is also a living historical and geological site where people have lived, interacted with and interpreted the shape of the country for upwards of forty thousand years.
Periodic Orbits in a Simple Ray-Splitting System

description: We study ray dynamics in a square billiard that allows mode conversion and is parametrised by $κ$, the ratio of the velocities of the two modes. At $κ\rightarrow 1^+$, conversion occurs at every reflection and periodic orbits proliferate exponentially. As $κ$ increases beyond $\sqrt{2}$, the collection of daughter rays explore only three momentum directions and mode conversion is progressively inhibited. We provide an algorithm for determining periodic orbits when $κ> \sqrt{2}$ and show numerically that exponential proliferation persists around $κ\simeq \sqrt{2}$ but as $κ$ increases, a crossover to sub-exponential behaviour occurs for short periods. We discuss these results in the light of conservation laws.
