description: Gene transformer models such as Nucleotide Transformer, DNABert, and LOGO are trained to learn optimal gene sequence representations by using the Masked Language Modeling (MLM) training objective over the complete Human Reference Genome. However, the typical tokenization methods employ a basic sliding window of tokens, such as k-mers, that fail to utilize gene-centric semantics. This could result in the (trivial) masking of easily predictable sequences, leading to inefficient MLM training. Time-variant training strategies are known to improve pretraining efficiency in both language and vision tasks. In this work, we focus on using curriculum masking where we systematically increase the difficulty of masked token prediction task by using a Pointwise Mutual Information-based difficulty criterion, as gene sequences lack well-defined semantic units similar to words or sentences of NLP domain. Our proposed Curriculum Masking-based Gene Masking Strategy (CM-GEMS) demonstrates superior representation learning capabilities compared to baseline masking approaches when evaluated on downstream gene sequence classification tasks. We perform extensive evaluation in both few-shot (five datasets) and full dataset settings (Genomic Understanding Evaluation benchmark consisting of 27 tasks). Our findings reveal that CM-GEMS outperforms state-of-the-art models (DNABert-2, Nucleotide transformer, DNABert) trained at 120K steps, achieving similar results in just 10K and 1K steps. We also demonstrate that Curriculum-Learned LOGO (a 2-layer DNABert-like model) can achieve nearly 90% of the state-of-the-art model performance of 120K steps. We will make the models and codes publicly available at https://github.com/roysoumya/curriculum-GeneMask.

description: A fundamental question about the nature of quantum materials such as High-T$_c$ systems remain open to date -- it is unclear whether they are (some variety of) Fermi liquids, or (some variety of) non Fermi liquids. A direct avenue to determine their nature is to study the (imaginary part of the) self-energy at low energies. Here we present a novel method to extract this low $ω$ self-energy from experimentally derived spectral functions. The method seems suited for implementation with high quality angle resolved photoemission data. It is based on a helpful Theorem proposed here, which assures us that the method has minimal (or vanishing) error at the lowest energies. We provide numerical examples showing that a few popular model systems yield distinguishably different low energy self-energies.

Why Naive Quark Model Can Yield a Good Account of the Baryon Magnetic Moments

description: The chiral quark model suggests that the baryon quark-sea is negatively polarized. This modifies the spin structure as given by the naive quark model and agrees with experimental data. However, for the magnetic moments, there is significant cancellation between the contritutions from this sea spin-polarization and the orbital angular momentum so that effectively the moments are given by the valence constituent quarks alone, as in the NQM.

description: The supersymmetry self-consistent approximation for the model of non-equilibrium thermodynamic system with quenched disorder is derived from the dynamical action calculated by means of generalized second Legendre transformation. The equations for adiabatic and isothermal susceptibilities, memory and field induced parameters are obtained on the basis of asymptotic analysis of dynamical Dyson equations. It is shown that the marginal stability condition that defines the critical point is governed by fluctuations violating FDT. The temperature of ergodicity breaking transition is calculated as a function of quenched disorder intensities. Transformation of superfields related to the mapping between an instanton process and the corresponding causal solution is discussed.

description: Excerpts from the report Preface: A study was conducted in the warehouses of typical independent poultry and egg wholesale distributors in New York, Chicago, Philadelphia, and Washington, D.C., by the Handling and Facilities Research Branch of the Transportation and Facilities Research Division, Agricultural Marketing Service, U.S. Department of Agriculture. The report is based on studies of facilities under actual operating conditions, to determine the feasibility of modernizing outdated plant structures. Modern specialized service needs were considered, and remodeling was judged to be in feasible. New structures and layouts that would provide facilities capable of operating with efficiency, flexibility, and good sanitation are described in the report. The structure and layout recommendations provide guidelines for facilities similar in dimensions to those in multiple-occupancy warehouses located in modern food-distribution centers. They also provide flexibility that permits a choice of service operations in a single layout at commodity volume levels and combinations prevalent in today's wholesale poultry and egg business.

description: We examine effects of the next-nearest-neighbor repulsion on electronic states of a one-dimensional interacting electron system which consists of quarter-filled band and interactions of on-site and nearest-neighbor repulsion. We derive the effective Hamiltonian for the electrons around wave number $\pm \kf$ ($\kf$: Fermi wave number) and apply the renormalization group method to the bosonized Hamiltonian. It is shown that the next-nearest-neighbor repulsion makes $4\kf$-charge ordering unstable and suppresses the spin fluctuation. Further the excitation gaps and spin susceptibility are also evaluated.

description: We introduce a new theoretical approach to dissipative quantum systems. By means of a continuous sequence of infinitesimal unitary transformations, we decouple the small quantum system that one is interested in from its thermodynamically large environment. This yields a trivial final transformed Hamiltonian. Dissipation enters through the observation that generically observables ``decay'' completely under these unitary transformations, i.e. are completely transformed into other terms. As a nontrivial example the spin-boson model is discussed in some detail. For the super-Ohmic bath we obtain a very satisfactory description of short, intermediate and long time scales at small temperatures. This can be tested from the generalized Shiba-relation that is fulfilled within numerical errors.

description: The familiar $c\rightarrow \infty$ nonrelativistic limit converts the Klein-Gordon equation in Minkowski spacetime to the free Schroedinger equation, and the Einstein-massive-scalar system without a cosmological constant to the Schroedinger-Newton (SN) equation. In this paper, motivated by the problem of stability of Anti-de Sitter (AdS) spacetime, we examine how this limit is affected by the presence of a negative cosmological constant $Λ$. Assuming for consistency that the product $Λc^2$ tends to a negative constant as $c\rightarrow \infty$, we show that the corresponding nonrelativistic limit is given by the SN system with an external harmonic potential which we call the Schrodinger-Newton-Hooke (SNH) system. We then derive the resonant approximation which captures the dynamics of small amplitude spherically symmetric solutions of the SNH system. This resonant system turns out to be much simpler than its general-relativistic version, which makes it amenable to analytic methods. Specifically, in four spatial dimensions, we show that the resonant system possesses a three-dimensional invariant subspace on which the dynamics is completely integrable and hence can be solved analytically. The evolution of the two-lowest-mode initial data (an extensively studied case for the original general-relativistic system), in particular, is described by this family of solutions.

description: Background: Haematometra which is a rare complication can occur after Caesarean section, thus leading to a presentation at a gynaecological clinic. Case Reported: We report a case of a 32-year-old P1+0 (not alive) woman who presented at the gynaecological clinic of our facility with secondary amenorrhea of 7 months duration and abdominal pain of 5 months duration. She underwent Caesarean section for prolonged obstructed labour with delivery of a fresh still birth neonate at term at another facility prior to presentation. An abdomino-pelvic ultrasound scan was ordered which suggested haematometra. She subsequently had dilatation and 200ml of serosanguineous blood fluid was sunctioned. Conclusion: Haematometra which is a rare complication can occur after a Caesarean section with serious morbidities following poor surgical techniques especially in a primigravida with risk factors. The right surgical techniques should be employed to prevent these complications.

description: Excitons in semiconductors can form a variety of collective states leading to different regimes of exciton propagation. Here we theoretically demonstrate the possibility to reach the viscous hydrodynamic -- liquid-like -- regime of exciton propagation in two-dimensional materials, focusing on the mono- and bi-layers of transition metal dichalcogenides. This regime can be realized where the exciton-exciton collisions dominate over exciton-phonon and disorder scattering. We have derived the hydrodynamic-like set of equations describing viscous flow of interacting excitons based on the Boltzmann kinetic equation for the exciton distribution function. A comparison of various exciton propagation regimes including diffusive, viscous hydrodynamic, and superfluid regime is presented. Conditions which allow one to observe the hydrodynamic regime of exciton transport, and the role of material are discussed.

Quantitative symmetry breaking of groundstates for a class of weighted Emden-Fowler equations

Year: 2018
Subjects: subject: Analysis of PDEs (math.AP)

description: We consider a class of weighted Emden-Fowler equations \begin{equation} \tag{$\mathcal P_α$} \label{eqab} \left\{\begin{array}{ll} -Δu=V_α (x) \, u^p & \text{in} \,\,B,\\ u>0 & \text{in} \,\,B,\\ u=0 & \text{on}\,\,\partial B, \end{array}\right. \end{equation} posed on the unit ball $B=B(0,1)\subset \mathbb R^N$, $N \geq1$. We prove that symmetry breaking occurs for the groundstate solutions as the parameter $α\rightarrow \infty.$ The above problem reads as a possibly large perturbation of the classical Hénon equation. We consider a radial function $V_α$ having a spherical shell of zeroes at $|x|=R \in (0,1].$ For $N \geq 3$, a quantitative condition on $R$ for this phenomenon to occur is given by means of universal constants, such as the best constant for the subcritical Sobolev's embedding $H^1_0(B)\subset L^{p+1}(B).$ In the case $N=2$ we highlight a similar phenomenon when $R=R(α)$ is a function with a suitable decay. Moreover, combining energy estimates and Liouville type theorems we study some qualitative and quantitative properties of the groundstate solutions to (\ref{eqab}) as $α\rightarrow \infty.$

Evolution of Semi-convective Staircases in Rotating Flows: Consequences for Fuzzy Cores in Giant Planets

description: Recent observational constraints on the internal structure of Jupiter and Saturn suggest that these planets have ``fuzzy" cores, i.e., gradients of the concentration of heavy elements that might span a large fraction of the planet's radius. These cores could be composed of a semi-convective staircase, i.e., multiple convective layers separated by diffusive interfaces arising from double-diffusive instabilities. However, to date, no study has demonstrated how such staircases can avoid layer mergers and persist over evolutionary time scales. In fact, previous work has found that these mergers occur rapidly, leading to only a single convective layer. Using 3D simulations, we demonstrate that rotation prolongs the lifetime of a convective staircase by increasing the timescale for both layer merger and erosion of the interface between the final two layers. We present an analytic model for the erosion phase, predicting that rotation increases the erosion time by a factor of approximately $\mathrm{Ro}^{-1/2}$, where $\mathrm{Ro}$ is the Rossby number of the convective flows (the ratio of the rotation period to the convective turnover time). For Jovian conditions at early times after formation (when convection is vigorous enough to mix a large fraction of the planet), we find the erosion time to be roughly $10^{9}~\mathrm{yrs}$ in the non-rotating case and $10^{11}~\mathrm{yrs}$ in the rotating case. If these timescales are confirmed with a larger suite of numerical simulations, the existence of convective staircases within the deep interiors of giant planets is a strong possibility, and rotation could be an important factor in the preservation of their fuzzy cores.

description: One of the central goals of LISA is the detection of gravitational waves from the merger of supermassive black holes. Contrary to stellar-mass black hole mergers, such events are expected to be rich X-ray sources due to the accretion of material from the circumbinary disks onto the black holes. The orbital dynamics before merger is also expected to modulate the resulting X-ray emission via Doppler boosting in a quasi-periodic way, and in a simple phase relation with the gravitational wave from the inspiral of the black holes. Detecting the X-ray source would enable a precise and early localization of the binary, thus allowing many telescopes to observe the very moment of the merger. Although identifying the correct X-ray source in the relatively large LISA sky localization will be challenging due to the presence of many confounding point sources, the quasi-periodic modulation may aid in the identification. We explore the practical feasibility of such idea. We simulate populations of merging supermassive black holes, their detection with LISA and their X-ray lightcurves using a simple model. Taking the parameters of the X-ray Telescope on the proposed NASA Transient Astrophysics Probe, we then design and simulate an observation campaign that searches for the modulated X-ray source while LISA is still observing the inspiral of the black holes. Assuming a fiducial LISA detection rate of $10$ mergers per year at redshift closer than $3.5$, we expect a few detections of modulated X-ray counterparts over the nominal duration of the LISA mission.

description: With the emergence of space launch systems featuring recoverable reusable rocket stages, Europe and Japan are investigating their own way and merge their capabilities in developing CALLISTO Flight Demonstrator. As such, this original project relies on assets from JAXA in Japan on one hand, and DLR and CNES in Europe on the other hand. Intent of both parties is to collect direct knowledge and data in operating a space launch stage-like vehicle being recoverable (in vertical position) and then flown several times over a short period of time with minimized maintenance effort in between two flights from Space Center in French Guiana. One core contribution to this project is the rocket propulsion system from JAXA. It is a heavily reusable pump fed rocket engine mixing liquid oxygen and hydrogen and having a long heritage already. In addition, this robust engine offers a wide range of thrust setting capability and then gives design engineers flexibility in adapting flight paths in terms of range, altitude, speed and maneuvers to be (in flight) tested. The mission analysis is also enriched by CALLISTO advanced Flight Control System combining Thrust vectoring, Reaction Control and, last but not the least, a set of 4 aerosurfaces. In addition to airborne maneuvers, and thanks to systems sourced from DLR (Approach Landing System, Hybrid Navigation System e.g.), accurate landing with various vertical touch down speeds is a primary objective as well. This paper provides a status of the CALLISTO project focusing on flight envelope and vehicle design matters and how they interrelate with each other.

description: Until now, the Cabibbo Kobayashi Maskawa matrix element, $|V_{cb}|$, has always been measured in $B$ decays, i.e.~at an energy scale $q_b\sim \frac{m_b}{2}$, far below the weak scale. We consider here the possibility of measuring it close to the weak scale, at $q_W\sim m_W$, in top decays at the Large Hadron Collider (LHC). Our proposed method would use data from the LHC experiments in hadronic top decays $t\rightarrow bW\rightarrow b\overline{b} c$, tagged by the semileptonic decay of the associated top. We estimate the uncertainty of such a measurement, as a function of present and potential future experimental jet flavour-tagging performances, and conclude that first measurements using the data collected during 2016 - 2018 could yield a fractional error on \Vcb\ of order 7\% per experiment. We also give projected performances at higher luminosities, which could yield sensitivity to any Standard Model running of \Vcb\ below the weak scale, if present.

description: We report our density matrix renormalization-group and analytical work on S=1 antiferromagnetic Heisenberg spin chains. We study the finite size behavior within the framework of the non-linear sigma model. We study the effect of magnon-magnon interactions on the finite size spectrum and on the magnetization curve close to the critical magnetic field, determine the magnon scattering length and compare it to the prediction from the non-linear $σ$ model.

description: The mixed ferrite-cobaltites LnFe0.5Co0.5O3, with Ln = Eu & Dy have been prepared by a sol-gel method and the samples have been characterized using X-ray diffraction and electron microscopy. The magnetic investigations reveal that both samples ordered in canted antiferromagnetic structures near room temperature. The Dzyaloshinskii-Moriya or antisymmetric exchange interaction induces weak ferromagnetism due to canting of the antiferromagnetically ordered spins. In the case of Ln-Fe-Co orthoferrites, two magnetic sublattices (Ln3+-4f and Fe3+/Co3+-3d) generally align in opposite directions and interesting temperature dependent phenomena: e.g. uncompensated antiferromagnetic sublattices and spin-reorientations, are observed in the system. The existence of hysteresis at low temperature region has been explained in terms of the strength of magnetic interactions between Fe3+ and Co3+ ions with different A-site rare earth cations.

description: The three genera Geocaryum Coss., Conopodium W.D.J. Koch, and Bunium L. are closely related, and their correct identification is complex. The first two genera are distributed in Europe and North Africa, while several Bunium species also occur in Asia. In the present study, we analysed the chemical composition of the essential oil of the aerial parts of Geocaryum capillifolium (Guss.) Coss. a rare species collected in Sicily, which also grows in the Iberian Peninsula, Algeria, and Greece, was analysed using GC-MS. The main constituents of the essential oil were sesquiterpene hydrocarbons involving cis-β-farnesene (31.2%), trans-β-caryophyllene (20.0%), and germacrene D (8.5%). The chemical profile of the essential oil presented here was compared with the oils of previously investigated Geocaryum, Conopodium, and Bunium taxa, as reported in the literature. To the best of our knowledge, no report has been previously published about the essential oil of the Sicilian accession of this species.

description: We report on low-temperature photoconductivity (PC) in n-PbTe(Ga) epitaxial films prepared by the hot-wall technique on <111>-BaF_2 substrates. Variation of the substrate temperature allowed us to change the resistivity of the films from 10^8 down to 10_{-2} Ohm x cm at 4.2 K. The resistivity reduction is associated with a slight excess of Ga concentration, disturbing the Fermi level pinning within the energy gap of n-PbTe(Ga). PC has been measured under continuous and pulse illumination in the temperature range 4.2-300 K. For films of low resistivity, the photoresponse is composed of negative and positive parts. Recombination processes for both effects are characterized by nonexponential kinetics depending on the illumination pulse duration and intensity. Analysis of the PC transient proves that the negative photoconductivity cannot be explained in terms of nonequilibrium charge carriers spatial separation of due to band modulation. Experimental results are interpreted assuming the mixed valence of Ga in lead telluride and the formation of centers with a negative correlation energy. Specifics of the PC process is determined by the energy levels attributed to donor Ga III, acceptor Ga I, and neutral Ga II states with respect to the crystal surrounding. The energy level corresponding to the metastable state Ga II is supposed to occur above the conduction band bottom, providing fast recombination rates for the negative PC. The superposition of negative and positive PC is considered to be dependent on the ratio of the densities of states corresponding to the donor and acceptor impurity centers.

description: We show that an effective field theory that includes non-standard couplings between the electroweak gauge bosons and the top and bottom quarks may yield negative contributions to both the S and T oblique radiative electroweak parameters. We find that that such an effective field theory provides a better fit to data than the standard model (the chi-squared per degree of freedom is half as large). We examine in some detail an illustrative model where the exchange of heavy scalars produces the correct type of non-standard couplings.

description: From the early days of computing, games have been important testbeds for studying how well machines can do sophisticated decision making. In recent years, machine learning has made dramatic advances with artificial agents reaching superhuman performance in challenge domains like Go, Atari, and some variants of poker. As with their predecessors of chess, checkers, and backgammon, these game domains have driven research by providing sophisticated yet well-defined challenges for artificial intelligence practitioners. We continue this tradition by proposing the game of Hanabi as a new challenge domain with novel problems that arise from its combination of purely cooperative gameplay with two to five players and imperfect information. In particular, we argue that Hanabi elevates reasoning about the beliefs and intentions of other agents to the foreground. We believe developing novel techniques for such theory of mind reasoning will not only be crucial for success in Hanabi, but also in broader collaborative efforts, especially those with human partners. To facilitate future research, we introduce the open-source Hanabi Learning Environment, propose an experimental framework for the research community to evaluate algorithmic advances, and assess the performance of current state-of-the-art techniques.
