Supplementary diagnosis.
The external structure and male genitalia characteristics have been given and discussed in Qiu et al. (2018) and Han et al. (2024). So only female characteristics are added below: Supra-anal plate (TX) distinctly pubescent, with a slightly protruded posterior margin. Paraprocts (pp.) pubescent, the inner side extending to the middle in a curved hook. The two median sclerites generally wedged. Cerci short, not exceeding the posterior margin of supra-anal plate, setose and pubescent. Paratergites (pt.) irregularly-banded. Crosspiece (cp.) nearly transparent, with a small protuberance pointing toward the posterior lobes of valvifer II (sp. pl.). The base of posterior lobes of valvifer II fused with the anterior arch (aa.), forming into a circinate structure. Posterior lobes of valvifer II curved, the terminal part generally rounded. First valvule (v. I) long, basally connected to the basivalvula (bsv.) and spermathecal plate, gradually tapering from the base to the tip. Basal part of valvifer II (v. II) and valvifer III (v.

description: Vertical gold-nanogaps are created on microtubular cavities to explore the coupling between resonant light supported by the microcavities and surface plasmons localized at the nanogaps. Selective coupling of optical axial modes and localized surface plasmons critically depends on the exact location of the gold-nanogap on the microcavities which is conveniently achieved by rolling-up specially designed thin dielectric films into three dimensional microtube ring resonators. The coupling phenomenon is explained by a modified quasi-potential model based on perturbation theory. Our work reveals the coupling of surface plasmon resonances localized at the nanoscale to optical resonances confined in microtubular cavities at the microscale, implying a promising strategy for the investigation of light-matter interactions.

description: In the research sphere, data management as an aspect of research management has assumed tremendous significance, particularly with an expansion in the educational research enterprise. Data management represented by the acronym RDM describes the management and organization, storage, preservation, and sharing of data collected and used in a research undertaking. To this end, the study focused on data management in research practices in higher educational institutions: issues in the research sphere. Three research questions and hypotheses were formulated to guide the study, and the design adopted was ex-post facto with an accessible population of 790 data analysts in selected higher educational institutions in Nigeria. The study adopted the multistage sampling technique with a sample size of 385 (50%). The instrument used for data collection was a researchers’ validated instrument titled “Data Collection Scale for Researchers (DCSR)” which was validated using the inter-rater reliability method by experts in the field of Education and the coefficient of internal consistency ranged from 0.74 to 0.79. The data were analyzed using descriptive statistics (mean, standard deviation, and bar charts). The findings of the study revealed that most data analyzed were cooked (not real) irrespective of the fact that the results were quite outstanding. Also, most data were analyzed by quacks who do not have the required skills in research practices. The study, therefore, recommended the need for compulsory participation in workshops, seminars, and conferences by all lecturers, students, and other education researchers in the academic environment to produce a worthwhile output that will inform policy decisions. Conclusively, the study proposed the need for research and data
Survey of non-linear hydrodynamic models of type-II Cepheids

description: We present a grid on non-linear convective type-II Cepheid models. The dense model grids are computed for 0.6M_Sun and a range of metallicities ([Fe/H]=-2.0,-1.5,-1.0), and for 0.8M_Sun ([Fe/H]=-1.5). Two sets of convective parameters are considered. The models cover the full temperature extent of the classical instability strip, but are limited in luminosity; for the most luminous models violent pulsation leads to the decoupling of the outermost model shell. Hence, our survey reaches only the shortest period RV Tau domain. In the Hertzsprung-Russel diagram we detect two domains in which period doubled pulsation is possible. The first extends through the BL Her domain and low luminosity W Vir domain (pulsation periods ~2-6.5 d). The second domain extends at higher luminosities (W Vir domain; periods >9.5d). Some models within these domains display period-4 pulsation. We also detect very narrow domains (~10 K wide) in which modulation of pulsation is possible. Another interesting phenomenon we detect is double-mode pulsation in the fundamental mode and in the fourth radial overtone. Fourth overtone is a surface mode, trapped in the outer model layers. Single-mode pulsation in the fourth overtone is also possible on the hot side of the classical instability strip. The origin of the above phenomena is discussed. In particular, the role of resonances in driving different pulsation dynamics as well as in shaping the morphology of the radius variation curves is analysed.

A More Secure Split: Enhancing the Security of Privacy-Preserving Split Learning

Publisher: name: Zenodo

description: Split learning (SL) is a new collaborative learning technique that allows participants, e.g. a client and a server, to train machine learning models without the client sharing raw data. In this setting, the client initially applies its part of the machine learning model on the raw data to generate Activation Maps (AMs) and then sends them to the server to continue the training process. Previous works in the field demonstrated that reconstructing AMs could result in privacy leakage of client data. In addition to that, existing mitigation techniques that overcome the privacy leakage of SL prove to be significantly worse in terms of accuracy. In this paper, we improve upon previous works by constructing a protocol based on U-shaped SL that can operate on homomorphically encrypted data. More precisely, in our approach, the client applies homomorphic encryption on the AMs before sending them to the server, thus protecting user privacy. This is an important improvement that reduces privacy leakage in comparison to other SL-based works. Finally, our results show that, with the optimum set of parameters, training with HE data in the U-shaped SL setting only reduces accuracy by 2.65% compared to training on plaintext. In addition, raw training data privacy is preserved.

description: We consider the problem of optimal estimation of the linear functional $A_Nξ=\sum_{k=0}^Na(k)ξ(k)$ depending on the unknown values of a stochastic sequence $ξ(m)$ with stationary increments from observations of the sequence $ξ(m)+η(m)$ at points of the set $\mathbb{Z}\setminus\{0,1,2,\ldots,N\}$, where $η(m)$ is a stationary sequence uncorrelated with $ξ(m)$. We propose formulas for calculating the mean square error and the spectral characteristic of the optimal linear estimate of the functional in the case of spectral certainty, where spectral densities of the sequences are exactly known. We also consider the problem for a class of cointegrated sequences. We propose relations that determine the least favorable spectral densities and the minimax spectral characteristics in the case of spectral uncertainty, where spectral densities are not exactly known while a set of admissible spectral densities is specified.

description: We have systematically investigated the annealing effect on the structure and composition of the polar surface of SrTiO3 (111), starting with an ex-situ chemical etch. The relative surface concentration between Ti and Sr strongly depends on both the annealing temperature and the oxygen processing. There is a critical annealing temperature at which the maximum concentration ratio of Ti to Sr is achieved, while still maintaining a (1 x 1) surface structure. We demonstrate that with proper processing it is possible to avoid surface reconstruction over a broad temperature range. Our results provide an optimal temperature window for epitaxial film growth.

description: Riemann surfaces are geometric constructions in complex analysis that may represent multi-valued holomorphic functions using multiple sheets of the complex plane. We show that the energy dispersion of surface states in topological semimetals can be represented by Riemann surfaces generated by holomorphic functions in the two-dimensional momentum space, whose constant height contours correspond to Fermi arcs. This correspondence is demonstrated in the recently discovered Weyl semimetals and leads us to predict new types of topological semimetals, whose surface states are represented by double- and quad-helicoid Riemann surfaces. The intersection of multiple helicoids, or the branch cut of the generating function, appears on high-symmetry lines in the surface Brillouin zone, where surface states are guaranteed to be doubly degenerate by a glide reflection symmetry. We predict the heterostructure superlattice [(SrIrO$_3$)$_2$(CaIrO$_3$)$_2$] to be a topological semimetal with double-helicoid Riemann surface states.

description: Tungsten trioxide (WO$_3$) is a paradigmatic electrochromic material, whose peculiar optical properties in the presence of oxygen vacancies or intercalated alkali atoms have been observed and investigated for a long time. In this paper we propose a rationalization of experiments based on first-principles calculations of optical and electrical properties of oxygen deficient (reduced) WO$_3$. Our approach is based on a parameter-free dielectric-dependent hybrid density functional methodology, used in combination with the charge transition levels formalism, for studying excitation mechanisms in the presence of defects. Our results indicate that oxygen vacancies lead to a different physics in $γ$-monoclinic WO$_3$, depending on the orientation of the W-O-W chain where the vacancy is created, thus evidencing strong anisotropic effects rooted in the peculiar structural properties of the original nondefective monoclinic cell. Different types of oxygen vacancies can hence be classified on the basis of the calculated ground state properties, electronic structure, and excitation/emission energies, giving a satisfactory explanation to a range of experimental observations made on oxygen deficient WO$_3$.

description: We present results from our observing campaign of Comet 209P/LINEAR during its exceptionally close approach to Earth during May of 2014, the third smallest perigee of any comet in two centuries. These circumstances permitted us to pursue several studies of this intrinsically faint object, including measurements of gas and dust production rates, searching for coma morphology, and direct detection of the nucleus to measure its properties. Indeed, we successfully measured the lowest water production rates of an intact comet in over 35 years and a corresponding smallest active area, ~0.007 km^2. When combined with the nucleus size found from radar (Howell et al. 2014), this also yields the smallest active fraction for any comet, ~0.024%. In all, this strongly suggests that 209P/LINEAR is on its way to becoming an inert object. The nucleus was detected but could not easily be disentangled from the inner coma due to seeing variations and changing spatial scales. Even so, we were able to measure a double-peaked lightcurve consistent with the shorter of two viable rotational periods found by Hergenrother (2014). Radial profiles of the dust coma are quite steep, similar to that observed for some other very anemic comets and suggestive that vaporizing icy grains are present.

description: We present hydrodynamic simulations of stellar wind-magnetosphere interactions in hot Jupiters such as WASP-12b. For fiducial stellar wind rates we find that a planetary magnetic field of a few G produces a large magnetospheric cavity, which is typically 6-9 planetary radii in size. A bow shock invariably forms ahead of the magnetosphere, but the pre-shock gas is only mildly supersonic (with typical Mach numbers of $\simeq$1.6-1.8) so the shock is weak. This results in a characteristic signature in the ultraviolet light curve: a broad absorption feature that leads the optical transit by 10-20% in orbital phase. The shapes of our synthetic light-curves are consistent with existing observations of WASP-12b, but the required near-UV optical depth ($τ\sim 0.1$) can only be achieved if the shocked gas cools rapidly. We further show that radiative cooling is inefficient, so we deem it unlikely that a magnetospheric bow shock is responsible for the observed near-UV absorption. Finally, we apply our model to two other well-studied hot Jupiters (WASP-18b and HD209458b), and suggest that UV observations of more massive short-period planets (such as WASP-18b) will provide a straightforward test to distinguish between different models of circumplanetary absorption.

description: We report that in cylindrical nanorods skyrmion chains, i.e., three-dimensional spin textures, emerge dynamically, as revealed by micromagnetic simulations. The skyrmion-chain state occurs when the diameter of the rod is larger than the helical pitch length of the material, and the number of skyrmions on the chain is proportional to the length of the nanorod. This finding provides a deeper understanding of the interplay between geometry and skyrmionic symmetry, and shows how spatial confinement can stabilize spontaneous topological spin textures.

description: Invited talk at 9th KJ Workshop on Dark Energy. We discuss a cosmology based on a normalized propagator of low-energy quantum cosmology. Subsequent to the radiation-dominated era, it introduces a dynamical dark energy Λ=(1-q)H2 with no free parameters alleviating H0-tension in the late-time Universe between the Local Distance Ladder and Planck ΛCDM analysis of the CMB. Allowing for a small non-universal gravitational coupling g=1-ξα, preserving the astronomical age of the Universe and the BAO gives ξ=0.49±01, where α is the fine-structure constant. A round-off to ξ=1/2 predicts H0=(73.37±0.54)km/s/Mpc (van Putten, 2021, PLB , 823, 136737) consistent with H0=(73.30±1.04)km/s/Mpc reported subsequently in Riess et al. 2022, ApJ, 934, L7.

description: Single organic molecules offer great promise as bright, reliable sources of identical single photons on demand, capable of integration into solid-state devices. It has been proposed that such molecules in a crystalline organic matrix might be placed close to an optical waveguide for this purpose, but so far there have been no demonstrations of sufficiently thin crystals, with a controlled concentration of suitable dopant molecules. Here we present a method for growing very thin anthracene crystals from super-saturated vapour, which produces crystals of extreme flatness and controlled thickness. We show how this crystal can be doped with a widely adjustable concentration of dibenzoterrylene (DBT) molecules and we examine the optical properties of these molecules to demonstrate their suitability as quantum emitters in nanophotonic devices. Our measurements show that the molecules are available in the crystal as single quantum emitters, with a well-defined polarisation relative to the crystal axes, making them amenable to alignment with optical nanostructures. We find that the radiative lifetime and saturation intensity vary little within the crystal and are not in any way compromised by the unusual matrix environment. We show that a large fraction of these emitters are able to deliver more than $10^{12}$ photons without photo-bleaching, making them suitable for real applications.

description: Supercritical collisionless perpendicular shocks have an average macrostructure determined primarily by the dynamics of ions specularly reflected at the magnetic ramp. Within the overall macrostructure, instabilities, both linear and nonlinear, generate fluctuations and microstructure. To identify the sources of such microstructure, high-resolution two- and three-dimensional simulations have been carried out using the hybrid method, wherein the ions are treated as particles and the electron response is modelled as a massless fluid. We confirm the results of earlier 2-D simulations showing both field-parallel aligned propagating fluctuations and fluctuations carried by the reflected-gyrating ions. In addition, it is shown that, for 2-D simulations of the shock coplanarity plane, the presence of short-wavelength fluctuations in all magnetic components is associated with the ion Weibel instability driven at the upstream edge of the foot by the reflected-gyrating ions. In 3-D simulations we show for the first time that the dominant microstructure is due to a coupling between field-parallel propagating fluctuations in the ramp and the motion of the reflected ions. This results in a pattern of fluctuations counter-propagating across the surface of the shock at an angle inclined to the magnetic field direction, due to a combination of field-parallel motion at the Alfvén speed of the ramp, and motion in the sense of gyration of the reflected ions.

 Holotype:— MEXICO. Nuevo León: Monterrey, February 1880, E. Palmer 893 (K000478232!+ K000644337!, isotypes F! [V0093471 F], GH00219330!, NDG42382!, NY00335602!, P03512916!, PH00019771!, US 00110899!, US00866736!, WU!, YU002008!).
 Note: Nesom (1988, 2013) cites A. Gray as the author, but we believe this to be erroneous. Hemsley based the name Omphalodes aliena on Gray´s annotation of the sheet as “ A. Gr. MSS. in hb. Kew”, but Gray did not provide the diagnosis nor did he author the publication. Therefore, authorship is assigned to Hemsley (Art. 46.8.; McNeill et al. 2012). Hemsley cited a Palmer 873 specimen. This was clearly erroneous and is here corrected to 893 (Art. 9.2., McNeill et al. 2012), because Palmer 873 (K 000478556) is 1) from a different locality—Parras State—and 2) Gray annotated Palmer 893, not 873, as Omphalodes aliena. Gray (1884), Johnston (1924), and Nesom (1988, 2013) cited the correct type, but did not clarify the erroneous type citation by Hemsley.
 The sheet in Kew herbarium bears two barcodes for the two plants. However, there is no reason to assume that the two plants correspond to separate collections: The protologue provides characters of the flower (only visible on the upper plant) and the nutlets (only visible on the lower plant). There is one original label with an annotation that it was received by Kew in June 1881. The label bears an unpublished Watson name “ Leptocarya nudiflora ” and an updated name Omphalodes aliena “A.Gray ” [ex Hemsley]. The other “label” is a slip of ruled paper—without date of receipt and without Watson’s name—but with an undated note by Asa Gray. However, there is no indication that Gray did not see the original label (seemingly belonging to the upper plant), on the contrary. Nesom (1988) reports a hand-written note from Kew by Gray dated July 1881, in which he asks Watson to withhold the publication of his “ Leptocarya ”. Therefore, Gray must have seen the upper label as well as the upper plant. Nesom (2013) called the specimen with the Gray note “ holotype ” and distinguished the other one as isotype, but both are in fact part of the holotype specimen.
 The type sheet was annotated as “ Mimophytum aliena ” in 2005 by R. R. Mill, but the name has not been published.

description: The study explores deprived learning environment and delinquent behaviour among Undergraduates of Faculty of Education, University of Calabar, Nigeria. Survey research design was adopted for the study. The sampling techniques adopted for the study were census, purposive, proportionate and accidental; 601 respondents were drawn from the population of 8,400 undergraduate students of Faculty of Education in the 2018/2019 academic session. An instrument titled “Perceived Deprivation Factors and Truancy of Undergraduate Questionnaire,” validated through peer review, was used for data collection. The data was analyzed using simple statistical tools like frequency and percentages. The results showed perceived deprivation factors responsible for truancy among undergraduate students of the Faculty of Education to include poor lecturer-student interpersonal relationship, inaudibility of lecturers, lecturers' postponement of lectures/change of venue, peer influence, among others. Institutional factors suggested to curb truancy among the students include effective supervision of lecturers, effective guidance and counselling to help student focus on their studies, regular orientation programme especially to address adolescent students in class about truancy and its consequences among others.

Electromagnetic fields in the exterior of an oscillating relativistic star -- II. Electromagnetic damping

description: An important issue in the asteroseismology of compact and magnetized stars is the determination of the dissipation mechanism which is most efficient in damping the oscillations when these are produced. In a linear regime and for low-multipolarity modes these mechanisms are confined to either gravitational-wave or electromagnetic losses. We here consider the latter and compute the energy losses in the form of Poynting fluxes, Joule heating and Ohmic dissipation in a relativistic oscillating spherical star with a dipolar magnetic field in vacuum. While this approach is not particularly realistic for rapidly rotating stars, it has the advantage that it is fully analytic and that it provides expressions for the electric and magnetic fields produced by the most common modes of oscillation both in the vicinity of the star and far away from it. In this way we revisit and extend to a relativistic context the classical estimates of McDermott et al. Overall, we find that general-relativistic corrections lead to electromagnetic damping time-scales that are at least one order of magnitude smaller than in Newtonian gravity. Furthermore, with the only exception of $g$ (gravity) modes, we find that $f$ (fundamental), $p$ (pressure), $i$ (interface) and $s$ (shear) modes are suppressed more efficiently by gravitational losses than by electromagnetic ones.

description: This paper presents a detailed review of both theory and algorithms for the Cheeger cut based on the graph $1$-Laplacian. In virtue of the cell structure of the feasible set, we propose a cell descend (CD) framework for achieving the Cheeger cut. While plugging the relaxation to guarantee the decrease of the objective value in the feasible set, from which both the inverse power (IP) method and the steepest descent (SD) method can also be recovered, we are able to get two specified CD methods. Comparisons of all these methods are conducted on several typical graphs.

description: Stellar evolution models of massive stars are important for many areas of astrophysics, for example nucleosynthesis yields, supernova progenitor models and understanding physics under extreme conditions. Turbulence occurs in stars primarily due to nuclear burning at different mass coordinates within the star. The understanding and correct treatment of turbulence and turbulent mixing at convective boundaries in stellar models has been studied for decades but still lacks a definitive solution. This paper presents initial results of a study on convective boundary mixing (CBM) in massive stars. The 'stiffness' of a convective boundary can be quantified using the bulk Richardson number ($\textrm{Ri}_B$), the ratio of the potential energy for restoration of the boundary to the kinetic energy of turbulent eddies. A 'stiff' boundary ($\textrm{Ri}_B \sim 10^4$) will suppress CBM, whereas in the opposite case a 'soft' boundary ($\textrm{Ri}_B \sim 10$) will be more susceptible to CBM. One of the key results obtained so far is that lower convective boundaries (closer to the centre) of nuclear burning shells are 'stiffer' than the corresponding upper boundaries, implying limited CBM at lower shell boundaries. This is in agreement with 3D hydrodynamic simulations carried out by Meakin and Arnett [The Astrophysical Journal 667:448-475, 2007]. This result also has implications for new CBM prescriptions in massive stars as well as for nuclear burning flame front propagation in Super-Asymptotic Giant Branch stars and also the onset of novae.

 Abstract of the paper: Chemometrics and statistical ecology share interest in the analysis of multivariate data. In ecology, unconstrained and constrained ordination are popular methods to analyze and visualize multivariate data, with principal components analysis (PCA) and redundancy analysis (RDA) as prototype methods. Constraints give more insight and power by focusing on the response of the variables to particular external predictors or experimental factors, after optional adjustment for covariates. In chemometrics, analysis of variance - simultaneous component analysis (ASCA) was proposed decades later, with particular emphasis on the multivariate main and interaction effects in factorial experiments. This paper shows the similarities and differences between ASCA, its extensions, and (partial) RDA, alias reduced-rank regression. ASCA and RDA (understood as a sequence of partial RDAs, just as ASCA uses a sequence of PCAs) are shown to be mathematically identical for equireplicated designed experiments. Differences appear with unequal replication. As a corollary we show that, with equal replication, a particularly attractive form of ASCA, which displays a main effect together with an interaction, is a special case of principal response curve analysis. RDA is a least-squares method and uses the optimal weights in the dimension reduction of the treatment effects, whereas ASCA extensions for unbalanced data use alternative, sub-optimal weights.

description: We show that every quasipositive link has a quasipositive minimal braid representative, partially resolving a question posed by Orevkov. These quasipositive minimal braids are used to show that the maximal self-linking number of a quasipositive link is bounded below by the negative of the minimal braid index, with equality if and only if the link is an unlink. This implies that the only amphicheiral quasipositive links are the unlinks, answering a question of Rudolph's.

description: Three kinds of fractal solutions of model of reactors are presented. The first kind concerns the structure of Feigenbaum_s diagram on the limit of chaos. The second kind and the third one concern the effect of initial conditions on the dynamic solutions of models. In the course of computations two types of recirculation were considered, viz. the recirculation of mass (return of a part of products stream) and recirculation of heat (heat exchange in the external heat exchanger).
