description: The equation of state dependence of neutron star's astrophysical features modeling is key to our understanding of dense matter. However, there exists a series of almost equation-of-state independent relations reported in the literature, called quasi-universal relations, that are used to determine neutron star radii and moments of inertia from X-ray and gravitational wave signals. Using sets of equations of state constrained by multi-messenger astronomy measurements and nuclear-physics theory, we discuss quasi-universal relations in the context of future gravitational-wave detectors Cosmic Explorer and Einstein Telescope, and X-ray detector STROBE-X. We focus on relations that involve the moment of inertia $I$, the tidal deformability $Λ$ and the compactness $C$: $C(Λ)$, $I(Λ)$ and $I(C)$. The quasi-universal fits and their associated errors are constructed with three different microphysics approaches which include state of the art nuclear physics theory and astrophysical constraints. Gravitational-wave and X-ray signals are simulated with the sensitivity of the next generation of detectors. Equation of state inference on those simulated signals is performed to assess if quasi-universal relations will offer a better precision on the extraction of neutron star's macroscopic parameters than equation of state dependent relations. We show that detections with the 3rd generation of gravitational wave detectors and the X-ray detector STROBE-X will be sensitive to the fit error marginalization technique. We also find that the sensitivity of those detectors will be sufficient that using full equation of state distributions will offer better precision on extracted parameters than quasi-universal relations.We also note that nuclear physics theory offers a more pronounced equation of state invariance of quasi-universal relations than current astrophysical constraints.

description: Nearby young moving groups provide unique samples of similar age stars for testing the evolution of physical properties. Incomplete and/or incorrect group membership classifications reduce the usefulness of the group, which we assume to be coeval. With near-infrared spectra of two candidate members of the TW Hya Association, 2MASS J12354615$-$4115531 (TWA 46) and 2MASS J12371238$-$4021480 (TWA 47), we test their membership by adding radial velocity measurements to the literature. We find that 2MASS J12354615$-$4115531 is a close spectroscopic binary system with a center-of-mass radial velocity of -6.5$\pm$3.9 km s$^{-1}$. This radial velocity and a $\textit{Gaia}$ parallax produces a TWA membership probability of 41.9$\%$ using the Banyan $Σ$ tool for 2MASS J12354615$-$4115531. The spectrum of 2MASS J12371238$-$4021480 shows that it appears to be a single star with a radial velocity consistent with the TW Hya Association and a membership probability of 99.5$\%$. The reduced probability of TWA 46 as a true member of TWA highlights the importance of high-resolution, near-infrared spectra in validating low-mass moving group members.

description: In the past few decades, the placenta became a very controversial topic that has had many researchers and pharmacists discussing the significance of the effects of pharmaceutical drug intake and how it is a possible leading cause towards birth defects. The creation of an in vitro microengineered model of the placenta can be used to replicate the interactions between the mother and fetus, specifically pharmaceutical drug intake reactions. As the field of nanotechnology significantly continues growing, nanotechnology will become more apparent in the study of medicine and other scientific disciplines, specifically microengineering applications. This review is based on past and current research that compares the feasibility and testing of the placenta-on-a-chip microengineered model to the previous and underdeveloped in vivo and ex vivo approaches. The testing of the practicality and effectiveness of the in vitro, in vivo and ex vivo models requires the experimentation of prominent pharmaceutical drugs that most mothers consume during pregnancy. In this case, these drugs need to be studied and tested more often. However, there are challenges associated with the in vitro, in vivo and ex vivo processes when developing a practical placental model, which are discussed in further detail.

Semisimple orbits of Lie algebras and card shuffling measures on Coxeter groups

description: Solomon's descent algebra is used to define a family of signed measures M(W,x) for a finite Coxeter group W and non-zero x. The measures corresponding to W of types A and B are known to arise from the theory of card shuffling and to be related to the Poincare-Birkhoff-Witt theorem and splittings of Hochschild homology. Formulas for these measures are obtained in special cases. The eigenvalues of the associated Markov chains are computed. By elementary algebraic group theory, choosing a random semisimple orbit on a Lie algebra corresponding to a finite group of Lie type G^F induces a measure on the conjugacy classes of the Weyl group W of G^F. It is conjectured that this measure on conjugacy classes is equal to the measure arising from M(W,q) (and further that M(W,q) is non-negative on all elements of W). This conjecture is proved for all types for the identity conjugacy class of W, and is confirmed for all conjugacy classes for W of types A, B, and C.

description: B.C. Hydro is presently investigating the possibility of developing the Hat Creek coal deposit in south central British Columbia to produce coal for a thermal electric power plant. As part of the reclamation planning for this project, studies have been undertaken to examine the site specific factors likely to influence the future revegetation of waste piles. The rationale for this test program is described. Test plots have been constructed using a variety of discrete waste materials excavated during a bulk coal sample excavation program undertaken during the summer of 1977. In addition, plots to test revegetation at various slopes have been developed. A wide variety of revegetation species, suitable for establishment of vegetation in the dry climate at Hat Creek were examined and twelve were selected for testing. Three seed mixes of four species each were prepared. Each material was tested for nutrients and appropriate fertilizer was added during seeding. Material test plots were hand seeded with the three different seed mixes while plots to test revegetation at different slopes were hydroseeded using only one seed mix, a mulch and binder. A monitoring program will be undertaken to determine emergence success and productivity of species under each field test condition.

description: The formalism of exact 1D quantization is reviewed in detail and applied to the spectral study of three concrete Schrödinger Hamiltonians $[-\d^2/\d q^2 + V(q)]^\pm$ on the half-line $\{q>0\}$, with a Dirichlet (-) or Neumann (+) condition at q=0. Emphasis is put on the analytical investigation of the spectral determinants and spectral zeta functions with respect to singular perturbation parameters. We first discuss the homogeneous potential $V(q)=q^N$ as $N \to +\infty$vs its (solvable) $N=\infty$ limit (an infinite square well): useful distinctions are established between regular and singular behaviours of spectral quantities; various identities among the square-well spectral functions are unraveled as limits of finite-N properties. The second model is the quartic anharmonic oscillator: its zero-energy spectral determinants $\det(-\d^2/\d q^2 + q^4 + v q^2)^\pm$ are explicitly analyzed in detail, revealing many special values, algebraic identities between Taylor coefficients, and functional equations of a quartic type coupled to asymptotic $v \to +\infty$ properties of Airy type. The third study addresses the potentials $V(q)=q^N+v q^{N/2-1}$ of even degree: their zero-energy spectral determinants prove computable in closed form, and the generalized eigenvalue problems with v as spectral variable admit exact quantization formulae which are perfect extensions of the harmonic oscillator case (corresponding to N=2); these results probably reflect the presence of supersymmetric potentials in the family above.

description: These notes aim at providing a complete and systematic account of some foundational aspects of algebraic supergeometry, namely, the extension to the geometry of superschemes of many classical notions, techniques and results that make up the general backbone of algebraic geometry, most of them originating from Grothendieck's work. In particular, we extend to algebraic supergeometry such notions as projective and proper morphisms, finiteness of the cohomology, vector and projective bundles, cohomology base change, semicontinuity theorems, relative duality, Castelnuovo-Mumford regularity, flattening, Hilbert and Quot schemes, faithfully flat descent, quotient étale relations (notably, Picard schemes), among others. Some results may be found elsewhere, and, in particular, there is some overlap with a recent preprint by Moosavian and Zhou. However, many techniques and constructions are presented here for the first time, notably, a first development of Grothendieck relative duality for proper morphisms of superschemes, the construction of the Hilbert superscheme in a more general situation than the one already known (which in particular allows one to treat the case of sub-superschemes of supergrassmannians), and a rigorous construction of the Picard superscheme for a locally superprojective morphism of noetherian superschemes with geometrically integral fibres. Moreover, some of the proofs given here are new as well, even when restricted to ordinary schemes. In a final section we construct a period map from an open substack of the moduli of proper and smooth supercurves to the moduli stack of principally polarized abelian superchemes.

description: Effectively and efficiently retrieving images from remote sensing databases is a critical challenge in the realm of remote sensing big data. Utilizing hand-drawn sketches as retrieval inputs offers intuitive and user-friendly advantages, yet the potential of multi-level feature integration from sketches remains underexplored, leading to suboptimal retrieval performance. To address this gap, our study introduces a novel zero-shot, sketch-based retrieval method for remote sensing images, leveraging multi-level feature extraction, self-attention-guided tokenization and filtering, and cross-modality attention update. This approach employs only vision information and does not require semantic knowledge concerning the sketch and image. It starts by employing multi-level self-attention guided feature extraction to tokenize the query sketches, as well as self-attention feature extraction to tokenize the candidate images. It then employs cross-attention mechanisms to establish token correspondence between these two modalities, facilitating the computation of sketch-to-image similarity. Our method significantly outperforms existing sketch-based remote sensing image retrieval techniques, as evidenced by tests on multiple datasets. Notably, it also exhibits robust zero-shot learning capabilities and strong generalizability in handling unseen categories and novel remote sensing data. The method's scalability can be further enhanced by the pre-calculation of retrieval tokens for all candidate images in a database. This research underscores the significant potential of multi-level, attention-guided tokenization in cross-modal remote sensing image retrieval. For broader accessibility and research facilitation, we have made the code and dataset used in this study publicly available online. Code and dataset are available at https://github.com/Snowstormfly/Cross-modal-retrieval-MLAGT.

description: A model-based collaborative filtering (CF) approach utilizing fast adaptive randomized singular value decomposition (SVD) is proposed for the matrix completion problem in recommender system. Firstly, a fast adaptive PCA frameworkis presented which combines the fixed-precision randomized matrix factorization algorithm [1] and accelerating skills for handling large sparse data. Then, a novel termination mechanism for the adaptive PCA is proposed to automatically determine a number of latent factors for achieving the near optimal prediction accuracy during the subsequent model-based CF. The resulted CF approach has good accuracy while inheriting high runtime efficiency. Experiments on real data show that, the proposed adaptive PCA is up to 2.7X and 6.7X faster than the original fixed-precision SVD approach [1] and svds in Matlab repsectively, while preserving accuracy. The proposed model-based CF approach is able to efficiently process the MovieLens data with 20M ratings and exhibits more than 10X speedup over the regularized matrix factorization based approach [2] and the fast singular value thresholding approach [3] with comparable or better accuracy. It also owns the advantage of parameter free. Compared with the deep-learning-based CF approach, the proposed approach is much more computationally efficient, with just marginal performance loss.
Higher-Order Polynomial Invariants of 3-Manifolds Giving Lower Bounds for the Thurston Norm

description: We define an infinite sequence of new invariants, delta_n, of a group G that measure the size of the successive quotients of the derived series of G. In the case that G is the fundamental group of a 3-manifold, we obtain new 3-manifold invariants. These invariants are closely related to the topology of the 3-manifold. They give lower bounds for the Thurston norm which provide better estimates than the bound established by McMullen using the Alexander norm. We also show that the delta_n give obstructions to a 3-manifold fibering over S^1 and to a 3-manifold being Seifert fibered. Moreover, we show that the delta_n give computable algebraic obstructions to a 4-manifold of the form X x S^1 admitting a symplectic structure even when the obstructions given by the Seiberg-Witten invariants fail. There are also applications to the minimal ropelength and genera of knots and links in S^3.

description: We discuss a recently presented boosted Kerr black hole solution which had already been used by other authors. This boosted metric is based on wrong assumptions regarding asymptotic inertial observers and moreover the performed boost is not a proper Lorentz transformation. This note aims to clarify some of the issues when boosting black holes and the necessary care in order to interpret them. As it is wrongly claimed that the presented boosted Kerr metric is of Bondi-Sachs type, we recall out some of the necessary requirements and difficulties, when the casting the Kerr metric into a metric with a surface forming null coordinate.

description: We study the Coulomb glass emerging from the interplay of strong interactions and disorder in a model of spinless fermions on the Bethe lattice. In the infinite coordination number limit, strong interactions induce a metallic Coulomb glass phase with a pseudogap structure at the Fermi energy. Quantum and thermal fluctuations both melt this glass and induce a disordered quantum liquid phase. We combine self-consistent diagrammatic perturbation theory with continuous time quantum Monte-Carlo simulations to obtain the complete phase diagram of the electron glass, and to characterize its dynamical properties in the quantum liquid, as well as in the replica symmetry broken glassy phase. Tunneling spectra display an Efros-Shklovskii pseudogap upon decreasing temperatures, but the density of states remains finite at the Fermi energy due to residual quantum fluctuations. Our results bear relevance to the metallic glass phase observed in Si inversion layers.

Offline Deep Model Predictive Control (MPC) for Visual Navigation

Publisher: name: arXiv
Year: 2024
Subjects: subject: Robotics (cs.RO)
subject: FOS: Computer and information sciences

description: In this paper, we propose a new visual navigation method based on a single RGB perspective camera. Using the Visual Teach & Repeat (VT&R) methodology, the robot acquires a visual trajectory consisting of multiple subgoal images in the teaching step. In the repeat step, we propose two network architectures, namely ViewNet and VelocityNet. The combination of the two networks allows the robot to follow the visual trajectory. ViewNet is trained to generate a future image based on the current view and the velocity command. The generated future image is combined with the subgoal image for training VelocityNet. We develop an offline Model Predictive Control (MPC) policy within VelocityNet with the dual goals of (1) reducing the difference between current and subgoal images and (2) ensuring smooth trajectories by mitigating velocity discontinuities. Offline training conserves computational resources, making it a more suitable option for scenarios with limited computational capabilities, such as embedded systems. We validate our experiments in a simulation environment, demonstrating that our model can effectively minimize the metric error between real and played trajectories.

description: Nothura darwinii Darwin’s Nothura   Figs 1-2
 Two specimens from Paraguay labelled as Nothura darwinii are present in the Geneva collection: MHNG 1720.053 (female, 5 km east of Estancia Santa Sofia, Departamento Concepción, 30 September 1989, field number PY 7083, collected by Claude Vaucher and Alain de Chambrier) and MHNG 1720.054 (unsexed, 20 km south of Puente Zinho, Departamento Concepción, 6 November 1987, no field number and unknown collector). Both these specimens can be positively identified as Spotted Nothura Nothura maculosa on account of the following characteristics: i) barring present on both webs of the underside of the outer primaries, as seen in Fig. 2 (confined to the outer web in darwinii) (Conover, 1950); ii) tarsal measurements of 357 mm and 350 mm (darwinii being in the region 310-330 mm; Bump & Bump, 1969). Furthermore one of the specimens labelled as darwinii (MHNG 1720.053) was referred to as maculosa in field notes made by its collectors.
 Nothura darwinii was included without comment in the Paraguayan avifauna by Contreras et al. (1990) presumably on the basis of these specimens, and later listed by Hayes (1995) as a species for which “no details have been published”. Amarilla & Barreto (1999) list an undocumented sight record by B. Young from near Cerro León, Departamento Alto Paraguay in 1998 but this seems almost certain to be in error, that area being largely forested, subhumid as opposed to the arid habitats this species occupies in the rest of its range and regularly birded without any prior or additional records.
 Nothura darwinii occurs in Peru, Bolivia and Argentina, the latter two sharing land borders with Paraguay (Cabot, 1992; Schulenberg et al., 2007). In Argentina N. darwinii is distributed on the eastern slope of the Andes from Provincias Jujuy and Salta south through eastern La Pampa and southwestern Buenos Aires to Rio Negro and northern Chubut (Bump & Bump, 1969; Cabot, 1992; Davies, 2002). In Bolivia its distribution again is associated largely with uplands and foothills in La Paz, Cochabamba, Santa Cruz, Chuquisaca, Tarija and Oruro Departaments, where it occurs locally to 4300 m (Hennessy et al., 2003). In fact the closest Paraguayan territory comes to the known distribution of N. darwinii is extreme southwestern Boquerón department, and adjacent areas of Argentina and Bolivia in this area are occupied only by N. maculosa. Its presence in Paraguay must therefore be considered unlikely.

description: The paper is devoted to a model of a mesoscopic system consisting of a pair of parallel planar waveguides separated by an infinitely thin semitransparent boundary modeled by a transverse delta interaction. We develop the Birman-Schwinger theory for the corresponding generalized Schroedinger operator. The spectral properties become nontrivial if the barrier coupling is not invariant with respect to longitudinal translations, in particular, there are bound states if the barrier is locally more transparent in the mean and the coupling parameter reaches the same asymptotic value in both directions along the guide axis. We derive the weak-coupling expansion of the ground-state eigenvalue for the cases when the perturbation is small in the supremum and the L^1-norms. The last named result applies to the situation when the support of the leaky part shrinks: the obtained asymptotics differs from that of a double guide divided by a pierced Dirichlet barrier. We also derive an upper bound on the number of bound states.

We prove that the solution of the involution identity obeys blobbed topological recursion, which confirms a previous conjecture about the quartic Kontsevich model.

description: A kilonova, the electromagnetic emission produced by compact binary mergers, is formed through a delicate interplay of physical processes, involving r-process nucleosynthesis and interactions between heavy elements and photons through radiative transfer. This complexity makes it difficult to achieve a comprehensive understanding of kilonova spectra. In this study, we aim to enhance our understanding and establish connections between physical parameters and observables through radiative-transfer simulations. Specifically, we investigate how ejecta temperature and element mass influence the resulting kilonova spectrum. For each species, the strength of its line features depends on these parameters, leading to the formation of a distinct region in the parameter space, dubbed the Resonance Island, where the line signature of that species is notably evident in the kilonova spectrum. We explore its origin and applications. Among explored r-process elements (31$\leq$Z$\leq$92), we find that four species -- Sr$_{\rm II}$, Y$_{\rm II}$, Ba$_{\rm II}$, and Ce$_{\rm II}$ -- exhibit large and strong resonance islands, suggesting their significant contributions to kilonova spectra at specific wavelengths. In addition, we discuss potential challenges and future perspectives in observable heavy elements and their masses in the context of the resonance island.

description: We study bound-state solutions of the Klein-Gordon equation $φ^{\prime\prime}(x) =\big[m^2-\big(E-v\,f(x)\big)^2\big] φ(x),$ for bounded vector potentials which in one spatial dimension have the form $V(x) = v\,f(x),$ where $f(x)\le 0$ is the shape of a finite symmetric central potential that is monotone non-decreasing on $[0, \infty)$ and vanishes as $x\rightarrow\infty.$ Two principal results are reported. First, it is shown that the eigenvalue problem in the coupling parameter $v$ leads to spectral functions of the form $v= G(E)$ which are concave, and at most uni-modal with a maximum near the lower limit $E = -m$ of the eigenenergy $E \in (-m, \, m)$. This formulation of the spectral problem immediately extends to central potentials in $d > 1$ spatial dimensions. Secondly, for each of the dimension cases, $d=1$ and $d \ge 2$, a comparison theorem is proven, to the effect that if two potential shapes are ordered $f_1(r) \leq f_2(r),$ then so are the corresponding pairs of spectral functions $G_1(E) \leq G_2(E)$ for each of the existing eigenvalues. These results remove the restriction to positive eigenvalues necessitated by earlier comparison theorems for the Klein--Gordon equation.

Expanding Educational Empires: The USA, Great Britain, and British Africa, circa 1902-1944

description: “Expanding Educational Empires” explores the interventions of American philanthropic foundations in educational programs for British Africa after the First World War. It reveals the extent to which a discourse of education – pedagogy and research – allowed American philanthropic groups, and the numerous governmental and nongovernmental organizations with which they cooperated, to shape the interwar British Empire, and institutionalize a colonial ideology that aligned with American corporate and cultural interests. American philanthropists portrayed these interwar colonial activities as benevolent, apolitical enterprises, glossing over the fact that their influence over the overlapping agencies with which they cooperated filtered easily into official organs of power.
      By the 1940s, when the Anglo-American partnership no longer served the interests of American-based global capital, American philanthropists performed an effortless volte-face against a mercantilist British Empire. They now found it expedient to invoke both their nation’s ingrained hostility to colonialism and their expertise in native affairs, which had been attained primarily through support of interwar British imperialism, as justification for meddling in the postwar international arena, using education to construct a global community committed to corporate American preferences.
      This project investigates the close collaboration between American and British agents in the formulation of interwar colonial education, exposing it as a comprehensive program that entailed accumulating knowledge about British territories, particularly in Africa, and disseminating the findings worldwide, thereby establishing new ideological and economic international assumptions. It reveals that American interference in this ambitious project constituted an extension of the longstanding domestic state-building endeavors of early-twentieth-century American philanthropic foundation managers, and their partners. The “unofficial”, humanitarian framework of education allowed a web of American agents to smoothly and remarkably embed themselves in a foreign government’s operations with the ulterior motive of powering American international influence, a story that has significant implications today.
Reconstructing a non-linear interaction in the dark sector with cosmological observations

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: In this work we model two non-linear directly interacting scenarios in dark sector of the universe with the dimensionless parameter $α$ and $β$, which dominate the energy exchange between dark energy and dark matter. The central goal of this investigation is to research the interacting model and discuss the cosmological implications based on the current observational datasets. The class of the interaction is generally characterized by a coupling function $Q\propto H(z)ρ_x$, $x$ denotes the energy density of dark matter or dark energy. The constrained results we obtained indicate that the direct interaction in cosmic dark sector is favored by various observational data and the key effects on CMB power spectrum and linear matter power spectrum appear compared to $Λ$CDM standard paradigm. Finally, we discuss in depth the effect of different neutrino mass hierarchy on matter power spectrum and the variation of the ratio of CMB temperature power spectrum $C_{\ell}^{TT}$ and matter power spectrum $P(k)$ when the $ΔN_{eff}= N-3.046$ from 0.5 to 2, respectively.

Quench dynamics of spin in quantum dots coupled to spin-polarized leads

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We investigate the quench dynamics of a quantum dot strongly coupled to spin-polarized ferromagnetic leads. The real-time evolution is calculated by means of the time-dependent density-matrix numerical renormalization group method implemented within the matrix product states framework. We examine the system's response to a quench in the spin-dependent coupling strength to ferromagnetic leads as well as in the position of the dot's orbital level. The spin dynamics is analyzed by calculating the time-dependent expectation values of the quantum dot's magnetization and occupation. Based on these, we determine the time-dependence of a ferromagnetic-contact-induced exchange field and predict its nonmonotonic build-up. In particular, two time scales are identified, describing the development of the exchange field and the dot's magnetization sign change. Finally, we study the effects of finite temperature on the dynamical behavior of the system.

Change in data matrix and results of the phylogenetic analyses from The emblematic South African therocephalian Euchambersia in China: a new link in the dispersal of late Permian vertebrates across Pangea
Creators: name: Liu, Jun

Publisher: name: The Royal Society

description: Therapsids were widely distributed in Pangea in the late Permian. South Africa in Gondwana and Russia in Laurasia are the principal areas recording tetrapods (including therapsids) of this age. More recent field explorations have increased the importance of Chinese late Permian fossil assemblages. This is clearly reflected in the discovery of several new therocephalians from the Naobaogou Formation in Nei Mongol. Here, we report a therocephalian from that unit identified as a new species of the emblematic South African taxon Euchambersia. The new species, Euchambersia liuyudongi, is represented by a well-preserved skull and mandible showing a well-developed maxillary fossa and the absence of postcanine teeth. This is the third akidnognathid recovered from the Naobaougou Formation, but oddly, the two basal Chinese akidnognathids previously known were recovered from a younger unit of the formation than the derived E. liuyudongi. This is the first time that the same therocephalian genus is recorded in northern and southern continents, making the record of the Naobaougou Formation key to understanding the evolution of late Permian continental faunas in general, and of akidnognathid therocephalians in particular.
