description: A newly synthesized compound, ethyl 5-phenyl-2-(p-tolyl)-2H-1, 2, 3-triazole-4-carboxylate (EPPC) may be considered as a drug candidate and was exploited to study the structural and spectral properties by using quantum chemical calculation and multiple spectroscopic techniques. The results on theoretical spectrum of EPPC were consistent with experimental spectrum in great degree. In addition, EPPC has been as a special probe and investigated on the interactions with three kinds of blood proteins including human serum albumin (HSA), human immunoglobulin (HIgG) and bovine hemoglobin (BHb) by using UV–Vis, fluorescence spectroscopy and molecular modeling, respectively. Changes in various fluorescence and UV–Vis spectra were observed upon ligand binding along with a remarkable degree of fluorescence enhancement on complex formation under physiological condition with binding constant about 105 order of magnitudes, which caused the variations of conformation and microenvironment of these proteins in aqueous solution. The obtained results from the thermodynamic parameters calculated according to the van’t Hoff equation indicated that the entropy change ΔS° and enthalpy change ΔH° were found to be 0.168 KJ/mol K and 22.154 KJ/mol for EPPC-HSA system, 0.284 KJ/mol K and 54.408 KJ/mol for EPPC-HIgG system, and 0.228 KJ/mol K and 37.548 KJ/mol for EPPC-BHb system, respectively, which demonstrated that the primary binding pattern is determined by hydrophobic interaction. The results of docking and molecular dynamics simulation using three proteins crystal models revealed that EPPC could bind to three proteins well into hydrophobic cavity, which showed good consistence with the spectroscopic measurements.

Aphanogmus of Jeju Island (Hymenoptera: Ceraphronoidea)
Creators: name: Bastille, Owen
Publisher: name: Zenodo
Year: 2025

description:  

Ceraphronoidea is a dark taxon of microscopic parasitoid wasps, with much of its diversity comprised of undescribed species. Aphanogmus is easy to separate from other Hymenoptera based on simple antennal and wing vein characters. Aphanogmus species can easily be differentiated from each other using male genitalia. Our knowledge of South Korean Ceraphronoidea is limited. We describe one new, and report the presence of seven described Aphanogmus species based on 136 specimens from Jeju Island. We also explore the utility of external morphological characters to corroborate our male genitalia-based species concepts using synchrotron-based micro-CT 3D reconstruction.

description: We study the problem of minimizing the supremum norm, on a segment of the real line or on a compact set in the plane, by polynomials with integer coefficients. The extremal polynomials are naturally called integer Chebyshev polynomials. Their factors, zero distribution and asymptotics are the main subjects of this paper. In particular, we show that the integer Chebyshev polynomials for any infinite subset of the real line must have infinitely many distinct factors, which answers a question of Borwein and Erdélyi. Furthermore, it is proved that the accumulation set for their zeros must be of positive capacity in this case. We also find the first nontrivial examples of explicit integer Chebyshev constants for certain classes of lemniscates. Since it is rarely possible to obtain an exact value of integer Chebyshev constant, good estimates are of special importance. Introducing the methods of weighted potential theory, we generalize and improve the Hilbert-Fekete upper bound for integer Chebyshev constant. These methods also give bounds for the multiplicities of factors of integer Chebyshev polynomials, and lower bounds for integer Chebyshev constant. Moreover, all the mentioned bounds can be found numerically, by using various extremal point techniques, such as weighted Leja points algorithm. Applying our results in the classical case of the segment $[0,1]$, we improve the known bounds for the integer Chebyshev constant and the multiplicities of factors of the integer Chebyshev polynomials.

description: Learning classifier systems (LCSs) are evolutionary machine learning algorithms, flexible enough to be applied to reinforcement, supervised and unsupervised learning problems with good performance. Recently, self organizing classifiers were proposed which are similar to LCSs but have the advantage that in its structured population no balance between niching and fitness pressure is necessary. However, more tests and analysis are required to verify its benefits. Here, a variation of the first algorithm is proposed which uses a parameterless self organizing map (SOM). This algorithm is applied in challenging problems such as big, noisy as well as dynamically changing continuous input-action mazes (growing and compressing mazes are included) with good performance. Moreover, a genetic operator is proposed which utilizes the topological information of the SOM's population structure, improving the results. Thus, the first steps in structured evolutionary machine learning are shown, nonetheless, the problems faced are more difficult than the state-of-art continuous input-action multi-step ones.

description: We derive the semiclassical series for the partition function in Quantum Statistical Mechanics (QSM) from its path integral representation. Each term of the series is obtained explicitly from the (real) minima of the classical action. The method yields a simple derivation of the exact result for the harmonic oscillator, and an accurate estimate of ground-state energy and specific heat for a single-well quartic anharmonic oscillator. As QSM can be regarded as finite temperature field theory at a point, we make use of Feynman diagrams to illustrate the non-perturbative character of the series: it contains all powers of $\hbar$ and graphs with any number of loops; the usual perturbative series corresponds to a subset of the diagrams of the semiclassical series. We comment on the application of our results to other potentials, to correlation functions and to field theories in higher dimensions.

description: The paper addresses the dynamic impact of channel flows of water and mixtures of water and sediments on a test wall. Two types of impact may occur: the first characterized by the formation of a complete reflected wave moving upstream; the second type consisting in the vertical deviation of the flow along the wall with a jet-like behaviour. The paper deepens this second type of impact. During the impact of the flow against the wall, the pressure distribution along the wall and the impact force were measured. In order to explain the phenomenon, a rational approach based on the conservation equations for mass, momentum and energy was adopted; from this approach some simplified solutions were derived. We discuss the possible effects of the impact of single gravel particles and the influence of the dimensionless groups that govern the phenomenon. A good agreement between the experimental data and the results of the theoretical approach was obtained.

description: The X-ray crystal structures of HDAC8 complexed with Largazole thiol (LAR, PubChem CID: 56663191) and its synthetic variants (Ligand ID in PDB, PubChem CID: L6G, 91667418; L7G, 91667421; L8G, 91667420) (PDB Codes: 3RQD, 4RN0, 4RN2 and 4RN1) were analysed using molecular dynamics simulations to comprehend protein-ligand non-bonding energies (NBEs). The NBEs of ligands’ substructures vis-à-vis active site indicated that pyridyl fragment (F2B4) in L7G and L8G, and amide fragment (F2B5) in LAR and L6G are in high energy states. Based on ligands’ substructures and active site residues properties new compounds were designed by introducing phenolic and amidine moieties, respectively, for F2B4 and F2B5. This improved NBEs of new compounds (NC2, -60.93 kcal/mol; NC3, -42.42 kcal/mol). Also, Zn2+ group (substructure F1) of largazoles was modified with that of SAHA and Trapoxin A. Here, the results indicated in favor of Zn2+ group of Trapoxin A. New compound NC6 incorporating aforesaid modifications i.e., phenolic moiety for F2B4, amidine moiety for F2B5 and Zn2+ group of Trapoxin A in F1, offered best interactions with HDAC8 (-89.75 kcal/mol). Thus, the study revealed new depsipeptides as potential HDAC8 inhibitors.

description: The usual reading of logical implication "A implies B" as "if A then B" fails in intuitionistic logic: there are formulas A and B such that "A implies B" is not provable, even though B is provable whenever A is provable. Intuitionistic rules apparently do not capture interesting meta-properties of the logic and, from a computational perspective, the programs corresponding to intuitionistic proofs are not powerful enough. Such non-provable implications are nevertheless admissible, and we study their behavior by means of a proof term assignment and related rules of reduction. We introduce V, a calculus that is able to represent admissible inferences, while remaining in the intuitionistic world by having normal forms that are just intuitionistic terms. We then extend intuitionistic logic with principles corresponding to admissible rules. As an example, we consider the Kreisel-Putnam logic KP, for which we prove the strong normalization and the disjunction property through our term assignment. This is our first step in understanding the essence of admissible rules for intuitionistic logic.

description: Systolic blood pressure (BP) variability at daytime and nighttime, also known as BP dip, has shown its clinical value in diagnosis and treatment of cardiovascular diseases (CVDs). A model agnostic meta learning (MAML)-based 24-hour personalized approach is proposed in this paper for BP estimation using wrist photoplethysmography (PPG) signals from smart watch in free-living context. 
Detection of cuffinflation is adopted to avoid reactive hyperemia effect after deflation and to accomplish synchronization between reference BP values measured by the ambulatory BP monitoring (ABPM) device and recorded 24-hour PPG signals in the processing flow during the experiment. The assessment of signal quality and activity occurrence is incorporated to indicate the applicability of BP estimation. The fast adaptability of personal model is enhanced by pre-training with the MAML technique and thus only few data for fine-tuning in the testing task are required. 
From the experimental results, our approach achieves diurnal and nocturnal SBP estimation error of 0.89 ± 7.78 mmHg from 14 recruited subjects with ages from 20 to 90 years old and shows the feasibility of tracking BP variability with smart watch in daily life.

description: The site- and bond-dilution effects of the nonmagnetic ground state of a two-dimensional $S=1/2$ antiferromagnetic Heisenberg model, coupled with the lattice distortions on a square lattice, are investigated by performing quantum Monte Carlo simulations. In the nondiluted system, a phase diagram parameterized by the interchain interaction and the elastic constant is obtained, and the values of the lattice distortions in the dimerized phase are evaluated precisely. In the diluted system, we compare two ground-state energies assuming two patterns of lattice distortions with magnetic moments (effective spins) induced near the diluted parts and induced at the midpoint between the diluted parts. As a result, we find that it is difficult to induce effective spins near diluted parts for large elastic constants, small interchain interactions, and large concentrations of dilution.

description: We describe a general construction principle which allows to add colour values to a coupling constant dependent scattering matrix. As a concrete realization of this mechanism we provide a new type of S-matrix which generalizes the one of affine Toda field theory, being related to a pair of Lie algebras. A characteristic feature of this S-matrix is that in general it violates parity invariance. For particular choices of the two Lie algebras involved this scattering matrix coincides with the one related to the scaling models described by the minimal affine Toda S-matrices and for other choices with the one of the Homogeneous sine-Gordon models with vanishing resonance parameters. We carry out the thermodynamic Bethe ansatz and identify the corresponding ultraviolet effective central charges.

description: The earliest seed plants occur in the Late Devonian (Famennian). However, why and how they rapidly diversified remain long-standing mysteries. We investigated the early evolution of seed plants based on a new ovule and evaluated wind pollination performance of the earliest cupulate ovules by using computed fluid-dynamics simulations. Zaijunia biloba gen. et sp. nov. is described from the Upper Devonian (Famennian) of South China, and shows canonical hydrasperman-type ovules with lobed integuments and a complex nucellar apex. Zaijunia bears ovules in pairs, each ovule within a lateral bilobed cupule. We propose that duplication of the bi-ovulate fertile unit of Zaijunia could produce more complex derivative cupulate ovules, as an evolutionary pathway leading to the early diversification of seeds. We performed computed fluid-dynamics simulations of Zaijunia and two other early seed plants (i.e., Pseudosporogonites and Elkinsia), demonstrating that their fertile units improve airborne (pre)pollen capture efficiency. This study sheds additional light on the evolution of cupulate ovules and their potential adaptions to anemophily, as one of the factors driving the earliest radiation of seed plants.

As the temperature is decreased below the Al superconducting transition, the Co resistance exhibits a significant dependence on both temperature and voltage. The differential resistance data show that the decay length for the proximity effect is much larger than we would simply expect from the exchange field of the ferromagnet.

description: COVID-19 has posed massive challenges related to health, economy, and the social fabric of the entire human population. To curb the spread of the virus, the Government of Pakistan initiated a vaccination campaign against COVID-19. The objective of this research was to assess the factors associated with COVID-19 vaccine acceptance or hesitancy. The data were collected telephonically using a cross-sectional survey design through a close-ended structured questionnaire from a sample of 1325 vaccinated and non-vaccinated individuals with a response rate of 38%. SPSS v. 26 was used to analyze the data. The study revealed that 73% of the respondents were male, half in the 40-49 age group, 78% living in urban areas, and 45% had a monthly income between 20,001-50,000 Pakistani rupees. People felt reluctant to get vaccinated because of myths and misinformation related to it. The socio-demographic factors including male, age 60-69, middle or higher level of education, marital status, currently employed, from middle socio-economic status, living in urban areas, high access to mass media, history of influenza vaccination, physical activity, and perceived good health status were significantly associated with COVID-19 vaccination uptake. Concerted efforts are needed to achieve vaccine targets for the broader population through understanding and identifying barriers to vaccination.

description: The SiO2/WO3/NiWO4 composites modified carbon nanofibers (SiWNi-CNFs) were prepared by a facile electrospinning method with following carbonization process under nitrogen atmosphere. The as-obtained SiWNi-CNFs were characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), X-ray photoelectron spectra (XPS), X-ray powder diffraction (XRD), FT-IR spectroscopy and Raman spectroscopy. As revealed by the electrochemical measurement, the SiWNi-CNFs prepared with SiW12/NiAc2 molar ratio of 1:1 presented best hydrogen evolution activity with a small Tafel slope (48 mV dec−1) among all the as-prepared samples. Notably, the as-prepared catalysts exhibit a small onset potential (0.29 V vs. reversible hydrogen electrode), high current density and excellent stability. The experimental results pointed that the SiWNi-CNFs processes more efficient hydrogen evolution properties than that other contrast samples. This is due to the SiO2/WO3/NiWO4 composite modified on the surface of carbon nanofibers can generate numerous active sites from the synergistic effect of each component. At the same time, the intimate combination of ternary oxide and carbon nanofibers can accelerate the electron transfer, enhance the stability and hinder the aggregation of active components during the carbonization. Moreover, the net-like structure stacked by carbon nanofibers should render the exposure of active sites and facilitate the mass transport for the HER process.

description: We study the dynamics of ferromagnetic spin systems quenched from infinite temperature to their critical point. We show that these systems are aging in the long-time regime, i.e., their two-time autocorrelation and response functions and associated fluctuation-dissipation ratio are non-trivial scaling functions of both time variables. This is exemplified by the exact analysis of the spherical model in any dimension D>2, and by numerical simulations on the two-dimensional Ising model. We show in particular that, for $1\ll s$ (waiting time) $\ll t$ (observation time), the fluctuation-dissipation ratio possesses a non-trivial limit value $X_\infty$, which appears as a dimensionless amplitude ratio, and is therefore a novel universal characteristic of non-equilibrium critical dynamics. For the spherical model, we obtain $X_\infty=1-2/D$ for 24 (mean-field regime). For the two-dimensional Ising model we measure $X_\infty\approx0.26\pm0.01$.

description: Learning classifier systems are adaptive learning systems which have been widely applied in a multitude of application domains. However, there are still some generalization problems unsolved. The hurdle is that fitness and niching pressures are difficult to balance. Here, a new algorithm called Self Organizing Classifiers is proposed which faces this problem from a different perspective. Instead of balancing the pressures, both pressures are separated and no balance is necessary. In fact, the proposed algorithm possesses a dynamical population structure that self-organizes itself to better project the input space into a map. The niched fitness concept is defined along with its dynamical population structure, both are indispensable for the understanding of the proposed method. Promising results are shown on two continuous multi-step problems. One of which is yet more challenging than previous problems of this class in the literature.

description: We performed an integrated spatial characterization of the stromal architecture surrounding and occupying tumor mass in hepatocellular carcinoma (HCC) using tumor margin samples paired with tumor core non-tumor liver tissues from 58 patients. By reanalyzing prior molecular and morphological datasets, we discovered opposing stromal architecture and clinical outcomes between SUR- and SUR+ HCC. Spatial proteomics revealed major patterns of cancer-associated stroma in HCC characterized by ECM deposition, metabolic preferences, and immunological features. Using Stereo-seq in combination with scRNA-seq, snRNA-seq, and snATAC-seq revealed 35 cell subsets (across fibroblast, immune and malignant cells) and their spatial coordinates with respect to tumor stroma. Especially, we defined 5 fibroblast subtypes with distinct ECM profiles and spatial positioning. CAF1_FAP were enriched in the occupying stroma of SUR- tumors, with widespread RUNX1 chromatin activity, and co-localized with PDCD1+CD8T cells forming immune-regulatory hubs. By contrast, CAF3_C7 were gathered in the surrounding stroma of SUR+ tumors, with increased chromatin activity of USF2, and were often accompanied by SPP1+Macrophages to form wound-healing hubs. The clinical relevance of these 2 fibroblast subsets was further validated as transcriptional signatures and protein markers. This study suggested that spatially heterogeneous fibroblast subpopulations may play a role in driving disease progression and immunologic processes in human cancer by shaping stromal architecture and we provided a reference for designing future spatial multi-omics profiling. A more comprehensive understanding of stromal heterogeneity across human tumors in the spatial context may generate novel biomarkers and therapeutic opportunities.

description: The dephasing influence of a dissipative environment reduces linear superpositions of macroscopically distinct quantum states (sometimes also called Schrödinger cat states) usually almost immediately to a statistical mixture. This process is called decoherence. Couplings to the environment with a certain symmetry can lead to slow decoherence. In this Letter we show that the collective coupling of a large number of two-level atoms to an electromagnetic field mode in a cavity that leads to the phenomena of superradiance has such a symmetry, at least approximately. We construct superpositions of macroscopically distinct quantum states decohering only on a classical time scale and propose an experiment in which the extraordinarily slow decoherence should be observable.

description: Urban and Bierman introduced a calculus of proof terms for the sequent calculus LK with a strongly normalizing reduction relation. We extend this calculus to simply-typed higher-order logic with inferences for induction and equality, albeit without strong normalization. We implement thiscalculus in GAPT, our library for proof transformations. Evaluating the normalization on both artificial and real-world benchmarks, we show that this algorithm is typically several orders of magnitude faster than the existing Gentzen-like cut-reduction, and an order of magnitude faster than any other cut-elimination procedure implemented in GAPT.

description: Using uniaxial stress to tune Si:B through the metal-insulator transition we find the conductivity at low temperatures shows an excellent fit to scaling with temperature and stress on both sides of the transition. The scaling functions yield the conductivity in the metallic and insulating phases, and allow a reliable determination of the temperature dependence in the critical regions on both sides of the transition.

description: A metal-insulator transition was induced by in-plane magnetic fields up to 27 T in homogeneously Sb-doped Si/SiGe superlattice structures. The localisation is not observed for perpendicular magnetic fields. A comparison with magnetoconductivity investigations in the weakly localised regime shows that the delocalising effect originates from the interaction-induced spin-triplet term in the particle-hole diffusion channel. It is expected that this term, possibly together with the singlet particle-particle contribution, is of general importance in disordered n-type Si bulk and heterostructures.

description: The sum in the title is a rational multiple of pi^n for all integers n=2,3,4,... for which the sum converges absolutely. This is equivalent to a celebrated theorem of Euler. Of the many proofs that have appeared since Euler, a simple one was discovered only recently by Calabi: the sum is written as a definite integral over the unit n-cube, then transformed into the volume of a polytope Pi_n in R^n whose vertices' coordinates are rational multiples of pi. We review Calabi's proof, and give two further interpretations. First we define a simple linear operator T on L^2(0,pi/2), and show that T is self-adjoint and compact, and that Vol(Pi_n) is the trace of T^n. We find that the spectrum of T is {1/(4k+1) : k in Z}, with each eigenvalue 1/(4k+1) occurring with multiplicity 1; thus Vol(Pi_n) is the sum of the n-th powers of these eigenvalues. We also interpret Vol(Pi_n) combinatorially in terms of the number of alternating permutations of n+1 letters, and if n is even also in terms of the number of cyclically alternating permutations of n letters. We thus relate these numbers with S(n) without the intervention of Bernoulli and Euler numbers or their generating functions.

description: Background: Although some studies have reported the beneficial effects of milk and dairy product consumption on osteoporosis and risk of fracture, the findings are conflicting. Purpose: We summarized earlier data on the association between milk and dairy intake and risk of osteoporosis and hip fracture through a meta-analysis. Methods: A systematic literature search of relevant reports published in PubMed, ISI (Web of Science), EMBASE, SCOPUS, and Google Scholar until August 2018 was conducted. Results: Total dairy intake was protectively associated with reduced risk of osteoporosis based on cross-sectional and case-control studies (0.63; 95% CI: 0.55–0.73). Milk consumption was not associated with the risk of osteoporosis (overall RR = 0.79; 95% CI: 0.57–1.08). In non-linear dose–response meta-analysis, increase intake of dairy (at the level of 0 to 250 grams per day) was associated with a reduced risk of osteoporosis (Pnonlinearty = 0.005). Meta-regression of included studies revealed an inverse linear association between dairy and milk intake and risk of osteoporosis; such that every additional 200-gram intake of dairy and milk was associated with a 22% and 37% reduced risk of osteoporosis, respectively. In terms of hip fracture, milk consumption was associated with a 25% reduced risk of hip fracture only in cross-sectional and case-control studies (overall RR = 0.75; 95%CI: 0.57–0.99). In linear meta-regression, every additional 200-gram milk intake per day was associated with a 9% greater risk of hip fracture in cohort studies. Conclusion: Despite an inverse association between milk and dairy intake and risk of osteoporosis and hip fracture in cross-sectional and case-control studies, no such association was seen in cohort studies. Given the advantages of the cohort over case-control studies, we concluded that a greater intake of milk and dairy products was not associated with a lower risk of osteoporosis and hip fracture
