description: While the radiation mechanism of fast radio bursts (FRBs) is unknown, coherent curvature radiation and synchrotron maser are promising candidates. We find that both radiation mechanisms work for a neutron star (NS) central engine with $B\gtrsim 10^{12}$ G, while for the synchrotron maser, the central engine can also be an accreting black hole (BH) with $B\gtrsim 10^{12}$ G and a white dwarf (WD) with $B\sim 10^8-10^9$ G. We study the electromagnetic counterparts associated with such central engines, i.e., nebulae for repeating FRBs and afterglows for non-repeating FRBs. In general, the energy spectrum and flux density of the counterpart depend strongly on its size and total injected energy. We apply the calculation to the nebula of FRB 121102 and find that the persistent radio counterpart requires the average energy injection rate into the nebula to be between $2.7\times10^{39}~{\rm erg/s}$ and $1.5\times10^{44}~{\rm erg/s}$, and the minimum injected energy be $6.0\times10^{47}~{\rm erg}$ in around $7$ yr. Consequently, we find that for FRB 121102 and its nebula: (1) WD and accretion BH central engines are disfavored; (2) a rotation-powered NS central engine works when $1.2\times10^{12}~{\rm G}\lesssim B\lesssim 7.8\times10^{14}~{\rm G}$ with initial period $P<180$ ms, but the radio emission must be more efficient than that in typical giant pulses of radio pulsars; and (3) a magnetic-powered NS central engine works when its internal magnetic field $B\gtrsim 10^{16}$ G. We also find that the radio-emitting electrons in the nebula could produce a significant rotation measure (RM), but cannot account for the entire observed RM of FRB 121102.

 Melanoxanthus senegalensis Candèze, 1859: 514. Lectotype ♁ du Sénégal (NHML).
MATÉRIEL NIMBA. — 1 individu: Lamotte, 1942.
 Comme son nom l’indique ce Melanoxanthus est originaire du Sénégal où, néanmoins, il n’est jamais très commun. On le rencontre aussi, çà et là, dans d’autres régions de l’Afrique occidentale, notamment en Guinée et en Côte d’Ivoire, mais les individus provenant de ces régions plus méridionales présentent souvent une réunion complète ou presque totale des deux taches noires, rondes, qui sont habituellement situées un peu en avant du disque du pronotum; de plus, cette large macule sinueuse jouxte le bord antérieur du pronotum, ce qui n’est pas souvent le cas chez la forme typique. Cette remarquable variété que je nomme conjonctus, nov. var., distinguera ces exemplaires de la forme nominative qui est, quant à elle, plutôt répandue dans les régions septentrionales du Sénégal et du Niger, et dont les deux taches pronotales noires ne fusionnent pas, mais sont au contraire toujours bien séparées l’une de l’autre.
Cette variété paraît peu fréquente, même en Côte d’Ivoire où pourtant de nombreuses récoltes d’Elateridae ont déjà été effectuées. Les seize exemplaires qui me permettent de la nommer sont des localités suivantes: Côte d’Ivoire: Lamto, 8.XI.1966, 8.IV.1968, et 20.V.1984, C. Girard, J.- M. Leroux (Holotype, 1 ♁, et paratypes, 6 ♁ et ♀); Guinée: mont Nimba, Yalanzou, 1 ♀, II-VI.1942, M. Lamotte; Tabuna, 21.V.1985, 1 ex., S. Mursin; Sierra Leone: Freetown, 2 ex., 1889, col. R.

description: In this paper a formula is proved for the general degeneracy locus associated to an oriented quiver of type A_n. Given a finite sequence of vector bundles with maps between them, these loci are described by putting rank conditions on arbitrary composites of the maps. Our answer is a polynomial in Chern classes of the bundles involved, depending on the given rank conditions. It can be expressed as a linear combination of products of Schur polynomials in the differences of the bundles. The coefficients are interesting generalizations of Littlewood-Richardson numbers. These polynomials specialize to give new formulas for Schubert polynomials.

description: In contrast to conventional (single-label) classification, the setting of multilabel classification (MLC) allows an instance to belong to several classes simultaneously. Thus, instead of selecting a single class label, predictions take the form of a subset of all labels. In this paper, we study an extension of the setting of MLC, in which the learner is allowed to partially abstain from a prediction, that is, to deliver predictions on some but not necessarily all class labels. We propose a formalization of MLC with abstention in terms of a generalized loss minimization problem and present first results for the case of the Hamming loss, rank loss, and F-measure, both theoretical and experimental.

description: We consider a quantum walk where a detector repeatedly probes the system with fixed rate $1/τ$ until the walker is detected. This is a quantum version of the first-passage problem. We focus on the total probability, $P_{\mathrm{det}}$, that the particle is eventually detected in some target state, for example on a node $r_{\mathrm{d}}$ on a graph, after an arbitrary number of detection attempts. Analyzing the dark and bright states for finite graphs, and more generally for systems with a discrete spectrum, we provide an explicit formula for $P_{\mathrm{det}}$ in terms of the energy eigenstates which is generically $τ$ independent. We find that disorder in the underlying Hamiltonian renders perfect detection: $P_{\mathrm{det}}=1$, and then expose the role of symmetry with respect to sub-optimal detection. Specifically, we give a simple upper bound for $P_{\mathrm{det}}$ that is controlled by the number of equivalent (with respect to the detection) states in the system. We also extend our results to infinite systems, for example the detection probability of a quantum walk on a line, which is $τ$-dependent and less than half, well below Polya's optimal detection for a classical random walk.

 C’est avec quelques doutes que j’attribue les trois exemplaires récoltés au Nimba (1 ♁, 2 ♀), à l’espèce décrite par Cobos du Congo, mais je dois avouer que les différences morphologiques que j’ai observées, notamment dans la ponctuation pronotale, ne m’ont pas vraiment convaincu de l’existence de deux espèces distinctes. En fait, de la série typique de ce Megapenthoides, qui ne compte que quatre individus, je n’ai vu que deux exemplaires (dont l’holotype), ce qui ne me semble pas suffisant pour identifier avec certitude ces petits Élatérides.
ÉCOLOGIE. — C’est une espèce sylvicole qui peut certainement se trouver aussi à la lisière des galeries forestières; deux des exemplaires du Nimba ont d’ailleurs été récoltés en battant le feuillage des arbustes de la strate basse d’une galerie forestière, mais à proximité de la lisière du bois, entre 750 et 850 mètres d’altitude.

 Ce petit Megapenthoides semble peu fréquent, et les recherches qui ont été effectuées dans les galeries forestières du Nimba depuis sa découverte n’ont permis la capture que de deux nouveaux échantillons. Je l’ai décrit sur deux exemplaires qui ont été trouvés dans des milieux arborés fortement défrichés, forêts secondarisées difficiles à définir, situées dans la zone du piedmont. Enfin, je l’ai repris en battant le feuillage des arbustes du sous-bois des galeries forestières du Zougué et du Gba. C’est donc une espèce sylvicole assez peu exigeante, qui fréquente parfois des biotopes plus ouverts que les sous-bois de la forêt.

description: The observed Higgs boson signals to-date could be due to having two quasi-degenerate 125 GeV scalar states in Nature. This kind of scenario tallies well with the predictions from the Next-to-Minimal Supersymmetric Standard Model (NMSSM). We have analysed the phenomenological NMSSM Higgs boson couplings and derived a parameterization of the signal strengths within the two quasi-degenerate framework. With essentially two parameters, it is shown that the combined strengths of the two quasi-degenerate Higgs states in the leptonic (and b-quark) decay channels depart from the Standard Model values in the opposite direction to those in the vector boson channels. We identify experimental measurements for distinguishing a single from a double Higgs scenarios. The proposed parameterization can be used for benchmarking studies towards establishing the status of quasi-degenerate Higgs scenarios.

description: The electromagnetic field of the ultrarelativistic Reissner-Nordstrom solution shows the physically highly unsatisfactory property of a vanishing field tensor but a nonzero, i.e., delta-like, energy density. The aim of this work is to analyze this situation from a mathematical point of view, using the framework of Colombeau's theory of nonlinear generalized functions. It is shown that the physically unsatisfactory situation is mathematically perfectly defined and that one cannot aviod such situations when dealing with distributional valued field tensors.

description: To date, more than 100 countries have implemented some type of quota for women in their national legislatures, leading to one of the most significant developments in the global composition of legislative bodies in the past twenty-five years. One remaining puzzle in understanding the global diffusion of electoral gender quotas is the strong clustering of shared domestic quota policies by region. In this project, I examine the importance of dyadic relationships between countries, including shared membership in inter- governmental organizations (IGOs), regional organizations (ROs), and women’s international non-governmental organizations (WINGOs) in explaining the timing and type of quota adoption. To do this, I employ a social network approach to quantitatively model global and temporal trends in gender quota adoption. Controlling for other possible domestic and transnational determinants, my results indicate that the strongest predictor of quota policy adoption and design is the existence of similar policies in neighboring countries. These results suggest that, in the case of gender quota adoption, domestic policymakers see surrounding states as their most salient reference group when deciding both whether and how to implement new policy.

description: The flower morphology and phenology of 10 healthy, profusely flowering wild male kiwifruit (Actinidia callosa var. strigillosa C. F. Liang) accessions growing in North Sikkim district in Sikkim state, Northeast India, were analysed in 2021–2022. There was distinct variation among the accessions in the number of flowers per inflorescence, number of sepals and petals, colour of the sepals, arrangement of the petals, and average number of stamens, as well as the timing and duration of flowering. Accessions SKNFF-04 and SKNLC-21 were superior in terms of pollinating traits, with the highest average numbers of flowers and stamens per vine and the longest duration of flowering. Principal component analysis (PCA) revealed that the first and second principal components (PC1 and PC2) had eigenvalues greater than 1 and together explained 95.13% of the variation. Hierarchical cluster analysis categorised the accessions into two major clusters: Cluster I with eight accessions and Cluster II with the two superior accessions. The presence of the pleiochasium inflorescence type among all the observed accessions is of particular significance, as it can increase the efficacy of male selection in kiwifruit breeding programmes. This research sets the stage for further investigations into the potential advantages and unique characteristics of wild kiwifruit germplasm.

description: We present a full description of the nonergodic properties of wavefunctions on random graphs without boundary in the localized and critical regimes of the Anderson transition. We find that they are characterized by two critical localization lengths: the largest one describes localization along rare branches and diverges with a critical exponent $ν_\parallel=1$ at the transition. The second length, which describes localization along typical branches, reaches at the transition a finite universal value (which depends only on the connectivity of the graph), with a singularity controlled by a new critical exponent $ν_\perp=1/2$. We show numerically that these two localization lengths control the finite-size scaling properties of key observables: wavefunction moments, correlation functions and spectral statistics. Our results are identical to the theoretical predictions for the typical localization length in the many-body localization transition, with the same critical exponent. This strongly suggests that the two transitions are in the same universality class and that our techniques could be directly applied in this context.

description: Within the framework of Becchi-Rouet-Stora-Tyutin (BRST) approach, we discuss mainly the fermionic (i.e. off-shell nilpotent) (anti-)BRST, (anti-)co-BRST and some discrete dual-symmetries of the appropriate Lagrangian densities for a two (1+1)-dimensional (2D) modified Proca (i.e. a massive Abelian 1-form) theory without any interaction with matter fields. One of the novel observations of our present investigation is the existence of some kinds of restrictions in the case of our present Stückelberg-modified version of the 2D Proca theory which is not like the standard Curci-Ferrari (CF)-condition of a non-Abelian 1-form gauge theory. Some kinds of similarities and a few differences between them have been pointed out in our present investigation. To establish the sanctity of the above off-shell nilpotent (anti-)BRST and (anti-)co-BRST symmetries, we derive them by using our newly proposed (anti-)chiral superfield formalism where a few specific and appropriate sets of invariant quantities play a decisive role. We express the (anti-)BRST and (anti-)co-BRST conserved charges in terms of the superfields that are obtained after the applications of (anti-)BRST and (anti-)co-BRST invariant restrictions and prove their off-shell nilpotency and absolute anticommutativity properties, too. Finally, we make some comments on (i) the novelty of our restrictions/obstructions, and (ii) the physics behind the negative kinetic term associated with the pseudo-scalar field of our present theory.

Index and Dynamics of Quantized Contact Transformations

description: Quantized contact transformations are Toeplitz operators over a contact manifold $(X,α)$ of the form $U_χ = ΠA χΠ$, where $Π: H^2(X) \to L^2(X)$ is a Szego projector, where $χ$ is a contact transformation and where $A$ is a pseudodifferential operator over $X$. They provide a flexible alternative to the Kahler quantization of symplectic maps, and encompass many of the examples in the physics literature, e.g. quantized cat maps and kicked rotors. The index problem is to determine $ind(U_χ)$ when the principal symbol is unitary, or equivalently to determine whether $A$ can be chosen so that $U_χ$ is unitary. We show that the answer is yes in the case of quantized symplectic torus automorphisms $g$---by showing that $U_g$ duplicates the classical transformation laws on theta functions. Using the Cauchy-Szego kernel on the Heisenberg group, we calculate the traces on theta functions of each degree N. We also study the quantum dynamics generated by a general q.c.t. $U_χ$, i.e. the quasi-classical asymptotics of the eigenvalues and eigenfunctions under various ergodicity and mixing hypotheses on $χ.$ Our principal results are proofs of equidistribution of eigenfunctions $ϕ_{Nj}$ and weak mixing properties of matrix elements $(Bϕ_{Ni}, ϕ_{Nj})$ for quantizations of mixing symplectic maps.

description: Figure S3. Generation by homologous recombination into the ROSA26 locus of a transgenic mouse allowing conditional ectopic expression of a human NANOS3 allele. The Gateway® Nanos3 entry clone was recombined with the ROSA26 destination vector (pROSA26-DV1) [28], using LR clonase. The targeting vector was replicated in bacteria, subsequently linearized (PvuI) and electroporated in ES cells, where homologous recombination with the wild type (WT) ROSA26 locus took place. Correctly targeted ES cells were selected (resistance to geneticin [neomycin-resistant cells] and diphtheria toxin A [DTA]) and screened by PCR and Southern blot analyses. The blue (G1 and G2) and green (Nanos3_F and Nanos3_R) arrows represent the sequencing primers used (Fig. 1d; Additional file 20: Table S1). The black and red rectangles represent the 5′ probe and neo probe, respectively, used for Southern blot analysis (Fig. 1c). The expected band sizes after genomic DNA digestion of the WT or knock-in allele with the corresponding restriction enzymes are indicated by the double-headed arrows. Cre-mediated loxP recombination allows expression of Nanos3 and the IRES-eGFP reporter under control of the ROSA26 promoter. The resulting mice were genotyped using the primers represented by black (Rosa_F, Rosa_R1 and Rosa_R2) and green arrows (Nanos3_F and Nanos3_R) (Additional file 20: Table S1). LoxP sites are represented by triangles. SA, splice acceptor site. (DOC 374 kb)

description: We address the estimation problem for general finite mixture models, with a particular focus on the elliptical mixture models (EMMs). Compared to the widely adopted Kullback-Leibler divergence, we show that the Wasserstein distance provides a more desirable optimisation space. We thus provide a stable solution to the EMMs that is both robust to initialisations and reaches a superior optimum by adaptively optimising along a manifold of an approximate Wasserstein distance. To this end, we first provide a unifying account of computable and identifiable EMMs, which serves as a basis to rigorously address the underpinning optimisation problem. Due to a probability constraint, solving this problem is extremely cumbersome and unstable, especially under the Wasserstein distance. To relieve this issue, we introduce an efficient optimisation method on a statistical manifold defined under an approximate Wasserstein distance, which allows for explicit metrics and computable operations, thus significantly stabilising and improving the EMM estimation. We further propose an adaptive method to accelerate the convergence. Experimental results demonstrate the excellent performance of the proposed EMM solver.

description: ICMP timestamp request and response packets have been standardized for nearly 40 years, but have no modern practical application, having been superseded by NTP. However, ICMP timestamps are not deprecated, suggesting that while hosts must support them, little attention is paid to their implementation and use. In this work, we perform active measurements and find 2.2 million hosts on the Internet responding to ICMP timestamp requests from over 42,500 unique autonomous systems. We develop a methodology to classify timestamp responses, and find 13 distinct classes of behavior. Not only do these behaviors enable a new fingerprinting vector, some behaviors leak important information about the host e.g., OS, kernel version, and local timezone.

description: We investigate the nucleon-nucleon interaction by using the meson exchange model and the two body Dirac equations of constraint dynamics. This approach to the two body problem has been successfully tested for QED and QCD relativistic bound states. An important question we wish to address is whether or not the two body nucleon-nucleon scattering problem can be reasonably described in this approach as well. This test involves a number of related problems. First we must reduce our two body Dirac equations exactly to a Schroedinger-like equation in such a way that allows us to use techniques to solve our two body Dirac equations already developed for Schroedinger-like systems in nonrelativistic quantum mechanics. Related to this we present a new derivation of Calogero's variable phase shift differential equation for coupled Schroedinger-like equations. Then we determine if the use of nine meson exchanges in our two body Dirac equations give a reasonable fit to the experimental scattering phase shifts for n-p scattering. The data involves seven angular momentum states including both singlet and the triplet spin states with orbital angular momentum 0,1,2. Two models that we have tested give us a fairly good fit. The parameters obtained by fitting the n-p experimental scattering phase shift give a fairly good prediction for most of the p-p experimental scattering phase shifts examined (for the spin singlet S and D states and spin triplet P states). Thus the two body Dirac equations of constraint dynamics presents us with a fit that encourages the exploration of a more realistic model. We outline generalizations of the meson exchange model for invariant potentials that may possibly improve the fit.

Impurity scattering induced carrier transport in twisted bilayer graphene

description: We theoretically calculate the impurity-scattering induced resistivity of twisted bilayer graphene at low twist angles where the graphene Fermi velocity is strongly suppressed. We consider, as a function of carrier density, twist angle, and temperature, both long-ranged Coulomb scattering and short-ranged defect scattering within a Boltzmann theory relaxation time approach. For experimentally relevant disorder, impurity scattering contributes a resistivity comparable to (much larger than) the phonon scattering contribution at high (low) temperatures. Decreasing twist angle leads to larger resistivity, and in general, the resistivity increases (decreases) with increasing temperature (carrier density). Inclusion of the van Hove singularity in the theory leads to a strong increase in the resistivity at higher densities, where the chemical potential is close to a van Hove singularity, leading to an apparent density-dependent plateau type structure in the resistivity, which has been observed in recent transport experiments. We also show that the Matthissen's rule is strongly violated in twisted bilayer graphene at low twist angles.

description: We define Albanese and Picard 1-motives of smooth (simplicial) schemes over a perfect field. For smooth proper schemes, these are the classical Albanese and Picard varieties. For a curve, these are t he homological 1-motive of Lichtenbaum and the motivic $H^1$ of Deligne. This paper proves a conjecture of Deligne about providing an algebraic description, via 1-motives, of the first homology and cohomology groups of a complex algebraic variety. (L. Barbieri-Viale and V. Srinivas have also proved this independently.) It also contains a purely algebraic proof of Lichtenbaum's conjecture that the Albanese and the Picard 1-motives of a (simplicial) scheme are dual. This gives a new proof of an unpublished theorem of Lichtenbaum that Deligne's 1-motive of a curve is dual to Lichtenbaum's 1-motive.
