Remarks.
Specimens of S. morsitans Linnaeus, 1758 collected from mainland Africa, originally identified as Scolopendra amazonica Bücherl, 1946 overlap with the specimens from the Aldabra Atoll in several characters (Table 2) (Lewis 1966, 1967, 1968, 1969), but generally have a greater number of glabrous basal antennal articles, a character in which specimens from the Aldabra Atoll more closely match Indian specimens of S. morsitans previously assigned to S. amazonica (Jangi 1955, 1959). In the absence of newly collected material from which molecular data can be collected to evaluate possible interspecific delimitation between different population of S. morsitans, we assign material collected in the Aldabra Atoll to S. morsitans, following the conclusions on interspecific variation within this taxon reached by Würmli (1975). Subsequent phylogenetic analyses of molecular data for S. morsitans identified multiple lineages within this taxon (Joshi and Karanth 2011; Siriwut et al. 2016), potentially indicating the existence of a cryptic species complex as suggested by recent taxonomic review (Lewis 2010 a). Until the global taxonomy of S. morsitans is interrogated using molecular data to establish if this is the case, we classify the examined material as S. morsitans.
Additionally, specimens were compared to the original description of the morphologically similar and geographically proximate Scolopendra antananarivoensis Kronmüller, 2010. Material from the Aldabra Atoll did not exhibit the characters given as diagnostic for S. antananarivoensis, lacking a longitudinal median depression on sternite 21 and not having a distinctly more elongate coxopleural process (Kronmüller 2010).

description: We study the contribution of charginos and neutralinos of the Minimal SUSY extension of the Standard model (MSSM) to the 1-loop vertices ZAA, ZZA, ZZZ, and examine the related cancellation of anomalies. It is found that when the SUSY parameter μsatisfies |μ| >> M,M', m_W, the couplings of charginos and neutralinos with the gauge bosons become purely vectorial, and then their contribution to the amplitudes for ZAA, ZZA and ZZZ vanish, which implies that this sector of the MSSM does not generate a Wess-Zumino term. We evaluate also the contribution of charginos and neutralinos to the ρparameter, and find that ρ=0 in the large-μlimit.

description: Flatband systems typically host "compact localized states"(CLS) due to destructive interference and macroscopic degeneracy of Bloch wave functions associated with a dispersionless energy band. Using a photonic Lieb lattice(LL), we show that conventional localized flatband states are inherently incomplete, with the missing modes manifested as extended line states which form non-contractible loops winding around the entire lattice. Experimentally, we develop a continuous-wave laser writing technique to establish a finite-sized photonic LL with specially-tailored boundaries, thereby directly observe the unusually extended flatband line states.Such unconventional line states cannot be expressed as a linear combination of the previously observed CLS but rather arise from the nontrivial real-space topology.The robustness of the line states to imperfect excitation conditions is discussed, and their potential applications are illustrated.

description: We determine the neutrino parameters for MSW and vacuum oscillations (active and sterile neutrinos) that are allowed by the separate, and collective, imposition of the constraints from total event rates in the chlorine, GALLEX, SAGE, and SuperKamiokande experiments (504 days), the SuperKamiokande electron energy spectrum, and the SuperKamiokande zenith-angle dependence. The small mixing angle MSW solution is acceptable at the 7% C.L. (8% for sterile nu's) and the vacuum solution is acceptable at the 6% C.L. . The best-fit global MSW solution for active neutrinos is: Delta m^2 = 5 x 10^-6 eV^2, sin^2 (2 theta) = 5.5 x 10^{-3} (and for sterile neutrinos: Delta m^2 = 4 x 10^-6 eV^2, sin^2 (2 theta) = 7 x 10^-3). For vacuum oscillations, the best-fit solution is: Delta m^2 = 6.5 x 10^-11 eV^2, sin^2 (2 theta) = 0.75 . An arbitrary combination of undistorted (no oscillations) pp, 7Be, 8B, and CNO neutrino fluxes is inconsistent with the combined data sets at the 3.5 sigma C.L., independent of astrophysical considerations. We use improved calculations of solar model fluxes, neutrino absorption cross sections and energy spectra, and a detailed evaluation of regeneration effects.

description: This paper provides insights into how variances in time spent by mothers in home production (i.e., domestic and care work) impact children’s diets. We test the hypothesis that a decrease in the time spent by mothers in home production negatively impacts children’s diets. Moreover, the paper considers whether substitute caregivers and improved water infrastructure can reduce these impacts. We use primary data from women traders in three markets in two regions in Ghana. Primary data collected from women traders includes women’s time use, the food consumed by children in the previous 24 hours, and the socio-economic and demographic characteristics of the traders’ households. To overcome the empirical challenge in estimating the relationship, we focus on the differences in the time spent by women traders in home production due to the differing demands on their time on “market” and “non-market” days. Market days are specified days for markets in a given geographic location. Market days are characterized by heightened trading activity, with more buyers and more competition. A comparison of the diets of traders’ children on market and non-market days allows for the attribution of effects to changes in the time spent by their mothers in home production while keeping other factors constant. The results suggest that children of women traders are significantly less likely to have achieved Minimum Meal Frequency (MMF) and Minimum Acceptable Diet (MAD) on market days compared to non-market days. This is accompanied by fewer hours spent by women in home production on market days. However, the paper also finds evidence that in certain scenarios the negative effect of demands on women traders’ time on children’s diets can be mitigated by substitute caregivers and the availability of water infrastructure.

description: The analytical solutions for the third-harmonic generation (THG) on infinite chains in both Su-Shrieffer-Heeger (SSH) and Takayama-Lin-Liu-Maki (TLM) models of trans-polyacetylene are obtained through the scheme of dipole-dipole ($DD$) correlation. They are not equivalent to the results obtained through static current-current ($J_0J_0$) correlation or under polarization operator $\hat{P}$. The van Hove singularity disappears exactly in the analytical forms, showing that the experimentally observed two-photon absorption peak (TPA) in THG may not be directly explained by the single electron models.

description: We employ U.S. Census Bureau data from cities of 10,000 or more to examine the impact of immigrants in American cities on self-employment and median income. The results show that self-employment has a statistically significant and positive impact on median income and immigrant population. When controlling for race populations, lagged immigrant population has a negative impact on self-employment, but removing the Hispanic control causes this relationship to become statistically insignificant. In other words, Hispanics, not other ethnici-ties, drive much of the self-employment in U.S. cities. An implication is that more attention to helping Hispanic business owners succeed and expand their businesses could benefit the general population of a city.

NHMUK 015991467, 1 juvenile, Casuarina litter, Picard, Aldabra, 10. 12. 1974, leg. V. W. Spaull.
Remarks.
The sexually immature specimen found in the present sample displays all diagnostic characters that support its assignment to Ribautia, comprising an elongate cephalic shield, lack of lappets on the first maxillae, the two halves of the second maxillary coxosternite being united by a sclerotised isthmus and the pleural sutures of the forcipular coxosternite being parallel to its lateral edge distally. A potentially novel ontogenetic observation is the incomplete separation of the two halves of the second maxillary coxosternite by an isthmus (Fig. 5 B), as is a characteristic of Ribautia. Taking into account the very small size (length 7 mm) and sexual immaturity of the specimen, this may be a character state that becomes more conspicuous in older individuals.
Beside the very low number of leg-bearing segments (37), which is shared with R. cf. paucipes reported from the Seychelles (Bonato and Minelli 2010), the developmental stage of the present specimen does not allow for satisfactory evaluation of potential morphological differences between Ribautia specimens described from Western Indian Ocean localities and type material of Ribautia paucipes described from the environs of Lake Kivu in Central Africa. Notably, the Aldabra specimen lacks evident denticles on the anterior margin of the forcipular coxosternite and the interior margin of the forcipular trochanteroprefemur, although these are clearly illustrated in the original description of R. paucipes (Attems 1952: fig. 203). The specimen also lacks conspicuous coxal organs or coxal pores, a character state not noted in R. cf. paucipes recorded from the Seychelles. Ontogenetic variation in the number of coxal pores has been well-documented for other geophilid centipedes (Horneland and Meidell 2009; Gregory and Barber 2010; Brena 2014; Stojanović et al. 2020), increasing with body size at each postembryonic stage, and being absent in comparably sized adolescens stages of some species (Gregory and Barber 2010). Additionally, the second maxillary pretarsus of the present specimen is markedly shorter and less acuminate than illustrated for R. paucipes from continental Africa. As the ontogenetic variation of the morphology of the second maxillae in Ribautia is not presently known and in other characters the specimen strongly resembles individuals described from the Seychelles, we maintain its presently assigned identity.

description: We revisit the problem of flux-balance equations for isolated post-Newtonian matter systems due to the emission of gravitational waves. In particular we show by a local derivation confined to the system, using the expression of radiation-reaction forces up to the 3.5PN order, that not only the energy, angular momentum and linear momentum of the system, but also the position of its center of mass, obey some (non-trivial) flux-balance equations. The balance equation for the center-of-mass position completes the description of the secular evolution by gravitational waves of relativistic post-Newtonian isolated matter systems. We then confirm this result by a direct computation of the gravitational-wave fluxes at future null infinity, obtaining the full multipole-moment expansion of the flux associated with the center-of-mass position (probably new with this paper), and rederiving as well the known multipole-moment expansions of the fluxes of energy, angular momentum and linear momentum. We also check our analysis by a direct calculation of radiation-reaction effects in the case of compact binary systems.

description: We present a detailed analysis of the free energy surface of a well characterized rigid model for water in supercooled states. We propose a functional form for the liquid free energy, supported by recent theoretical predictions [Y. Rosenfeld and P. Tarazona, Mol. Phys. {\bf 95}, 141 (1998)], and use it to locate the position of a liquid-liquid critical point at $T_{C'} = 130 \pm 5$~K, $P_{C'}=290\pm 30$MPa, and $ρ_{C'} = 1.10 \pm 0.03$~g/cm$^3$. The observation of the critical point strengthens the possibility that SPC/E water may undergo a liquid-liquid phase transition. Finally, we discuss the possibility that the approach to the liquid-liquid critical point could be pre-empted by the glass transition.

The light-cone Fock state expansion of wavefunctions provides a precise definition of the parton model and a general calculus for hadronic matrix elements. We present several new applications of light-cone Fock methods, including calculations of exclusive weak decays of heavy hadrons, and intrinsic heavy-quark contributions to structure functions. Discretized light-cone quantization, is outlined and applied to several gauge theories. We also discuss the construction of the light-cone Fock basis, the structure of the light-cone vacuum, and outline the renormalization techniques required for solving gauge theories within the Hamiltonian formalism on the light cone.

description: We present nuclear structure factors that describe the generalized spin-independent coupling of weakly interacting massive particles (WIMPs) to nuclei. Our results are based on state-of-the-art nuclear structure calculations using the large-scale nuclear shell model. Starting from quark- and gluon-level operators, we consider all possible coherently enhanced couplings of spin-1/2 and spin-0 WIMPs to one and two nucleons up to third order in chiral effective field theory. This includes a comprehensive discussion of the structure factors corresponding to the leading two-nucleon currents covering, for the first time, the contribution of spin-2 operators. We provide results for the most relevant nuclear targets considered in present and planned dark matter direct detection experiments: fluorine, silicon, argon, and germanium, complementing our previous work on xenon. All results are also publicly available in a Python notebook.

description: The motion of a vortex-(anti)vortex pair is studied numerically in the framework of a dynamical Ginzburg-Landau model, relevant to the description of a superconductor or of an idealized bosonic plasma. It is shown that up to a fine "cyclotron" internal motion, also studied in detail, two vortices brought together, rotate around each other, while a vortex and an antivortex move in formation parallel to each other. The velocities of the vortices in both cases are measured to be in remarkable agreement with recent theoretical predictions, down to intervortex distances as small as their characteristic diameter.

Interestingly, the gravitational constant $G$ is replaced by a novel fundamental constant, whose value is not tied to any classical phenomenon; while the value of $G$ itself becomes related to the dynamics of the universe. I concentrate on different aspects of the Equivalence Principle, as the theory is expected to violate all of its different formulations.

description: We consider the effect of disorder on the spectrum of quasiparticles in the point-node and nodal-line superconductors. Due to the anisotropic dispersion of quasiparticles disorder scattering may render the Hamiltonian describing these excitations non-Hermitian. Depending on the dimensionality of the system, we show that the nodes in the spectrum are replaced by Fermi arcs or Fermi areas bounded by exceptional points or exceptional lines, respectively. These features are illustrated by first considering a model of a proximity-induced superconductor in an anisotropic two-dimensional (2D) Dirac semimetal, where a Fermi arc in the gap bounded by exceptional points can be realized. We next show that the interplay between disorder and supercurrents can give rise to a 2D Fermi surface bounded by exceptional lines in three-dimensional (3D) nodal superconductors.

description: Energetics and conductance in jellium modelled nanowires are investigated using the local-density-functional-based shell correction method. In analogy with studies of other finite-size fermion systems, e.g., simple-metal clusters or He-3 clusters, we find that the energetics of the wire as a function of its radius (transverse reduced dimension) leads to formation of self-selecting magic wire configurations (MWC's, i.e., discrete sequence of wire radii with enhanced stability), originating from quantization of the electronic spectrum, namely formation of subbands which are the analogs of electronic shells in clusters. These variations in the energy result in oscillations in the force required to affect a transition from one MWC of the nanowire to another, and are correlated directly with step-wise variations of the quantized conductance of the nanowire in units of 2*e^2/h.

description: We use a novel cluster identification tool StarGO to explore the metal poor ([Fe/H] $$ 15 kpc) of the Milky Way using data from Gaia, LAMOST and SDSS. Our method is built using an unsupervised learning algorithm, a self-organizing map, which trains a 2-D neural network to learn the topological structures of a data set from an n-D input space. Using a 4-D space of angular momentum and orbital energy, we identify three distinct groups corresponding to the Sagittarius, Orphan, and Cetus Streams. For the first time we are able to discover a northern counterpart to the Cetus stream. We test the robustness of this new detection using mock data and find that the significance is more than 5-sigma. We also find that the existing southern counterpart bifurcates into two clumps with different radial velocities. By exploiting the visualization power of StarGO, we attach MW globular clusters to the same trained neural network. The Sagittarius stream is found to have five related clusters, confirming recent literature studies, and the Cetus stream has one associated cluster, NGC 5824. This latter association has previously been postulated, but can only now be truly confirmed thanks to the high-precision Gaia proper motions and large numbers of stellar spectra from LAMOST. The large metallicity dispersion of the stream indicates that the progenitor cannot be a globular cluster. Given the mean metallicity of the stream, we propose that the stream is the result of a merger of a low-mass dwarf galaxy that hosted a large nuclear star cluster (NGC 5824).

The rigorous quantitative relation between the amount of entanglement and the spatial coherence of particles is possible in this formalism. Our entanglement detection process is a generalization of the entanglement extraction protocol for identical particles with mode splitting proposed by Killoran et al. (2014).

description: The possibility to simulate the properties of many-body open quantum systems with a large number of degrees of freedom is the premise to the solution of several outstanding problems in quantum science and quantum information. The challenge posed by this task lies in the complexity of the density matrix increasing exponentially with the system size. Here, we develop a variational method to efficiently simulate the non-equilibrium steady state of Markovian open quantum systems based on variational Monte Carlo and on a neural network representation of the density matrix. Thanks to the stochastic reconfiguration scheme, the application of the variational principle is translated into the actual integration of the quantum master equation. We test the effectiveness of the method by modeling the two-dimensional dissipative XYZ spin model on a lattice.

description: Abstract

Modern scientific research has demonstrated that beehive products contain bioactive substances with medicinal applications. Among these products, propolis is a resinous substance harvested by bees on certain buds and barks of specific trees. The composition of propolis ensures various biological properties, including antibacterial, antifungal, antioxidant and anti-inflammatory effects. Propolis can find application in food packaging, utilizing its composition rich in bioactive compounds. A food film based on starch and propolis serves as an alternative to replace plastic materials, known to cause diseases such as cancer due to the harmful chemicals they contain and facing criticisms related to environmental impact. The primary focus of this study is on the physicochemical characteristics of propolis, especially polyphenols and flavonoids. The antioxidant activity of Algerian propolis ethanolic extract, obtained through different extraction methods, is evaluated. Antimicrobial activity was evaluated by measuring inhibition-zones diameters in millimeters for agar diffusion, along with determining the Minimum Inhibitory Concentration (MIC). Significant differences were observed between the three-propolis ethanolic extracts (PEEs) in the sensitivity to various tested strains. In terms of antioxidant activity, one of the three PEEs proves to be the most effective. Moreover, this study focuses on developing a food packaging film based on starch and PEF that has been most effective in preliminary analyses. The characteristics of the film, including thickness, moisture content, and biodegradability, were examined. The film's impact on the shelf life of strawberries has been explored, revealing an increased shelf life compared to market food film.
Dynamics, correlations and phases of the micromaser

description: The micromaser possesses a variety of dynamical phase transitions parametrized by the flux of atoms and the time-of-flight of the atom within the cavity. We discuss how these phases may be revealed to an observer outside the cavity using the long-time correlation length in the atomic beam. Some of the phase transitions are not reflected in the average excitation level of the outgoing atom, which is the commonly used observable. The correlation length is directly related to the leading eigenvalue of the time evolution operator, which we study in order to elucidate the phase structure. We find that as a function of the time-of-flight the transition from the thermal to the maser phase is characterized by a sharp peak in the correlation length. For longer times-of-flight there is a transition to a phase where the correlation length grows exponentially with the flux. We present a detailed numerical and analytical treatment of the different phases and discuss the physics behind them.

description: The paper provides an empirical examination of how research productivity distributions differ across scientific fields and disciplines. Productivity is measured using the FSS indicator, which embeds both quantity and impact of output. The population studied consists of over 31,000 scientists in 180 fields (10 aggregate disciplines) of a national research system. The Characteristic Scores and Scale technique is used to investigate the distribution patterns for the different fields and disciplines. Research productivity distributions are found to be asymmetrical at the field level, although the degree of skewness varies substantially among the fields within the aggregate disciplines. We also examine whether the field productivity distributions show a fractal nature, which reveals an exception more than a rule. Differently, for the disciplines, the partitions of the distributions show skewed patterns that are highly similar.
Constraints on the parameters of the Left Right Mirror Model

description: We study some phenomenological constraints on the parameters of a left right model with mirror fermions (LRMM) that solves the strong CP problem. In particular, we evaluate the contribution of mirror neutrinos to the invisible Z decay width (Γ_Z^{inv}), and we find that the present experimental value on Γ_Z^{inv}, can be used to place an upper bound on the Z-Z' mixing angle that is consistent with limits obtained previously from other low-energy observables. In this model the charged fermions that correspond to the standard model (SM) mix with its mirror counterparts. This mixing, simultaneously with the Z-Z' one, leads to modifications of the Γ(Z --> f \bar{f}) decay width. By comparing with LEP data, we obtain bounds on the standard-mirror lepton mixing angles. We also find that the bottom quark mixing parameters can be chosen to fit the experimental values of R_b, and the resulting values for the Z-Z' mixing angle do not agree with previous bounds. However, this disagreement disappears if one takes the more recent ALEPH data.

description: We consider the free carrier dispersion effect in a semiconductor nanocavity in the limit of discrete photoexcited electron-hole pairs. This analysis reveals the possibility of ultrafast, incoherent transduction and gain from a single photon signal to a strong coherent probe field. Homodyne detection of the displaced probe field enables a new method for room temperature, photon-number-resolving single photon detection. In particular, we estimate that a single photon absorbed within a silicon nanocavity can, within tens of picoseconds, be detected with $\sim 99\%$ efficiency and a dark count rate on the order of kHz assuming a mode volume $V_\text{eff}\sim 10^{-2}(λ/n_\text{Si})^3$ for a 4.5 micron probe wavelength and a loaded quality factor $Q$ on the order of $10^4$.

description: Automotive traffic is one of the largest drivers of greenhouse gas emissions in Europe. In order to achieve energy savings both, during the process and during the use phase of passenger cars, the powertrain components and their process chains will be optimized as part of the "Powertrain 2025" project. For this purpose, the implementation of an innovative process chain for the production of non-circular, microstructured and honed cylinder liners is being researched. Therefore, the paper introduces a new piezo-actuated hybrid tool, which was developed for the combination of non-circular turning and microstructuring of the cylinder liners in one tool. An integrated optical distance sensor measures after the process the workpiece geometry. This is used for quality control and as an input value for a process chain control that optimizes the process parameters and thus reduces the reject rate. After a short introduction of the new, energy-efficient process chain, the paper focuses on the concept and dimensioning of the new hybrid tool.

description: This work verifies whether research diversification by a scientist is in some measure related to their collaboration with multidisciplinary teams. The analysis considers the publications achieved by 5300 Italian academics in the sciences over the period 2004-2008. The findings show that a scientist's outputs resulting from research diversification are more often than not the result of collaborations with multidisciplinary teams. The effect becomes more pronounced with larger and particularly with more diversified teams. This phenomenon is observed both at the overall level and for the disciplinary macro-areas.
