description: We consider semigroups of operators for hierarchies of evolution equations of large particle systems, namely, of the dual BBGKY hierarchy for marginal observables and the BBGKY hierarchy for marginal distribution functions. We establish that the generating operators of the expansions for one-parametric families of operators of these hierarchies are the corresponding order cumulants (semi-invariants) of semigroups for the Liouville equations. We also apply constructed semigroups to the description of the kinetic evolution of interacting stochastic Markovian processes, modeling the microscopic evolution of soft active matter. For this purpose we consider the mean field asymptotic behavior of the semigroup generated by the dual BBGKY hierarchy for marginal observables. The constructed scaling limit is governed by the set of recurrence evolution equations, namely, by the Vlasov-type dual hierarchy. Moreover, the relationships of this hierarchy of evolution equations with the Vlasov-type kinetic equation with initial correlations are established.

description: Multifunctionality as a paradigm requires materials exhibiting multiple superior properties. Integrating second-order optical nonlinearity and large bandgap with piezoelectricity could, for example, enable broadband, strain-tunable photonics. Though very different phenomena at distinct frequencies, both second-order optical nonlinearity and piezoelectricity are third-rank polar tensors present only in acentric crystal structures. However, simultaneously enhancing both phenomena is highly challenging since it involves competing effects with tradeoffs. Recently, a large switchable ferroelectric polarization of ~ 80 uC cm-2 was reported in Zn1-xMgxO films. Here, ferroelectric Zn1-xMgxO is demonstrated to be a platform that hosts simultaneously a 30% increase in the electronic bandgap, a 50% enhancement in the second harmonic generation coefficients, and a near 200% improvement in the piezoelectric coefficients over pure ZnO. These enhancements are shown to be due to a 400% increase in the electronic anharmonicity and a ~200% decrease in the ionic anharmonicity with Mg substitution. Precisely controllable periodic ferroelectric domain gratings are demonstrated down to 800 nm domain width, enabling ultraviolet quasi-phase-matched optical harmonic generation as well as domain-engineered piezoelectric devices.

description: Two new organic electron-donors derived from carbazole and phenothiazine, 9-Octyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) carbazole-3-carbaldehyde and 10-octyl-7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxazine-3-carbaldehyde, have been synthesized successfully. The process was initiated with multistep reactions, alkylation, formylation, bromination and finally borylation, to give the final products. The successful formation of each structure was confirmed by IR, 1H NMR, 13C NMR, and HRMS. The newly synthesized key electron donors could have promising roles as key intermediates in different synthetic approaches.

description: Therapeutic grade, cytotoxic humanized anti-TRBV9 monoclonal antibody, investigational drug BCD-180, used for the preclinical studies was produced by BIOCAD (https://biocadglobal.com/). A single intravenous (i.v.) dose of BCD-180 administered to rhesus macaques (Macaca mulatta), resulted in prominent depletion of peripheral blood TRBV9+ T cells in a dose-dependent manner.
 Animals
 After quarantine, 12 Macaca mulatta males aged 5–8 years were selected for this experiment. For TCR repertoire profiling peripheral blood samples were collected before and 3, 40, 150, and 300 days after a single administration of BCD-180. We divided the animals into two groups (n = 4 for each group) that received 1 mg or 10 mg BCD-180 i.v. per animal, along with a control group that included four animals and received human intravenous IgG immunoglobulins (Microgen). Animals were kept in accordance with the guidelines for accommodation and care of laboratory animals, with species-specific provisions for nonhuman primates. The local ethics committee approved experiments for these studies.
 TCR repertoires
 Sequencing was performed on Illumina HiSeq1500. MIGEC was used for UMI-based read grouping and error correction. MiXCR was used for extraction of TCRβ CDR3 repertoires. VDJtools was used for downstream post-analysis. The repertoires inclide only productive sequences with more than one read per UMI.

description: We demonstrate an archetypal Loschmidt-echo experiment involving thousands of droplets which interact in a reversible fashion via a viscous fluid. Firstly, we show that, unlike equilibrium systems, periodically driven microfluidic emulsions self-organize and geometrically protect their macroscopic reversibility. Self-organization is not merely dynamical; we show that it has a clear structural signature akin to that found in a mixture of molecular liquids. Secondly, we show that, above a maximal shaking amplitude, structural order and reversibility are lost simultaneously in the form of a first order non-equilibrium phase transition. We account for this discontinuous transition in terms of a memory-loss process. Finally, we suggest potential applications of microfluidic echo as a robust tool to tailor colloidal self-assembly at large scales.

description: The binding affinity between the Spike (S) glycoprotein and its host cell receptors, angiotensin-converting enzyme 2 (ACE2) and Furin plays a critical role in determining SARS-CoV-2 replication rates. Variants of the S protein, including Alpha, Beta, Gamma, Delta, Omicron BA.1, BA.2, BA.4, and BA.5, have been associated with shifting levels of COVID-19 susceptibility and severity. However, the mechanisms underlying these virus-host protein interactions are not fully understood. The current research employs molecular modeling, protein-protein interaction, and molecular dynamics (MD) simulations of Wild-Type (WT) and variants of virus-host complexes ACE2-Spike-Furin to investigate interactions and stability. The objective is to gain a comprehensive understanding of protein complex dynamics and their relevance to COVID-19. Protein 3D structures were obtained from the Protein Data Bank, while MODELLER was employed to model S protein variants. Glycans were incorporated using the Glycan Reader & Modeller tool. Complexes were chosen based on HADDOCK scores, with lower scores signifying greater reliability. Interaction free energies were calculated using the PRODIGY server. MD simulations were conducted using GROMACS version 2019.3 with the CHARMM36 force field. The complexes were solvated, neutralized, minimized, and equilibrated under an NVT and NPT ensemble. The production phase was performed at 300K for 100ns. Complex selection was based on both the lowest HADDOCK scores and the free energies of each interaction. ACE2-Spike interactions displayed binding affinities ranging from -11.4 to -15.1 kcal/mol for WT Spike and its variants. Spike-Furin interactions exhibited affinities ranging from -10.5 to -12.6 kcal/mol. 28 glycans were incorporated into each complex. Throughout the MD simulations, all complexes demonstrated stability, as corroborated by RMSD, RMSF, Gyration, and SASA analyses, though with specific variations related to each variant. This project uniquely explores the interactions among three proteins and glycans, yielding high-fidelity complex models. These findings are an integral component of a comprehensive analysis that will additionally investigate the interactions of the TMPRSS2 protein and employ machine learning techniques to discern differences among SARS-CoV-2 lineages, aiming to understand genetic variations and gain insights into S protein dynamics, thereby enhancing our comprehension of SARS-CoV-2's protein-protein biology.

description: A novel approach to the synthesis of functionally substituted pyrazolopyrimidine, utilizing Ultrasound irradiation (US), microwave energy, and reaction under pressure in Q-tube as green and environmentally friendly techniques. The reaction time and yield of the products were compared in the three methods. A new compound, 5-benzoyl-6-hydroxy-4-phenyl-3,4-dihydropyrimidin-2(1H)-one was synthesized by conducting a Biginelli reaction under ultrasound irradiation. By following a reaction between an enaminones, aromatic aldehydes, and urea, in acetic acid, we observed that product obtained was dependent on applied reaction conditions in the presence of ammonium acetate. 1,3,5-triaroylbenzene was formed under pressure in Q-tube. Ultrasound irradiation of the same mixture led to a different end product. The chemical structures of these reaction products were firmly established using X-ray crystallography. In addition, a reaction mechanism to account for the formation of the observed effect was proposed.

description: Two of the most successful methods that are presently available for simulating the quantum dynamics of condensed phase systems are centroid molecular dynamics (CMD) and ring polymer molecular dynamics (RPMD). Despite their conceptual differences, practical implementations of these methods differ in just two respects: the choice of the Parrinello-Rahman mass matrix and whether or not a thermostat is applied to the internal modes of the ring polymer during the dynamics. Here we explore a method which is halfway between the two approximations: we keep the path integral bead masses equal to the physical particle masses but attach a Langevin thermostat to the internal modes of the ring polymer during the dynamics. We justify this by showing analytically that the inclusion of an internal mode thermostat does not affect any of the desirable features of RPMD: thermostatted RPMD (TRPMD) is equally valid with respect to everything that has actually been proven about the method as RPMD itself. In particular, because of the choice of bead masses, the resulting method is still optimum in the short-time limit, and the transition state approximation to its reaction rate theory remains closely related to the semiclassical instanton approximation in the deep quantum tunneling regime. In effect, there is a continuous family of methods with these properties, parameterised by the strength of the Langevin friction. Here we explore numerically how the approximation to quantum dynamics depends on this friction, with a particular emphasis on vibrational spectroscopy. We find that a broad range of frictions approaching optimal damping give similar results, and that these results are immune to both the resonance problem of RPMD and the curvature problem of CMD.

description: The aim of this deliverable is to illustrate the progress of the User-interface (UI) creation. This deliverable will provide an overview of the UI screenshots of both the mobile app for the patients and the web system for the physicians. UI mock-ups for the physician’s Web System and patient’s Mobile App are developed using Agile software development methods. According to the iterative approach, the figures with screenshots in Section 3 and Section 4 show the result of the second iteration of the UI development. The UIs prototypes created cover current functional requirements which are described in detail in the Deliverable D2.1 (Requirements Table and Use Case Description) in Sections 4.7 and 5.9. While producing the mock-ups, we considered that UIs should be user-friendly, simple, attractive, responsive, and clear to engage users and not create additional barriers. All elements that are placed on a layout are there for a reason: we try to predict the user's expectations and place key elements exactly where needed for an optimal interaction

description: Due to recent osteoarchaeological publications, prominent historians, archaeologists and osteologists have reignited the debate over the practice of infant and child sacrifice at Phoenician sites in the central Mediterranean. In all previous studies, including osteoarchaeological approaches, the debate has been conducted on terms established by the Greco-Roman sources. Here, I move away from those sources and suggest a series of demographic models in order to understand better the effects of infanticide on population growth at Phoenician colonies in the Early Iron Age central Mediterranean.

description: This paper calculates the elastic form factors for nucleons based on generalized parton distributions using an extended new ansatz introduced in http://dx.doi.org/10.1103/PhysRevC.105.025202 (Phys. Rev. C 105, no.2, 025202 (2022)). Different parton distribution functions (PDFs) are considered, and modifications are made to the free parameters of the new ansatz. The obtained results are systematically compared among the combinations of different PDFs and ansatzes for high ranges of momentum transfer, with $-t < 35 GeV^{-2}$. The minimum suitable parameters are used to parametrize the model. After obtaining the form factors, we proceed to compute the electric radius and the transversely unpolarized densities for the nucleon. In addition, we derive the parton distribution functions (PDFs) that depend on the impact parameter. Finally, we analyze the results by comparing them with the findings from other research and experimental data.

In a sample of 79 hot molecular cores, HC$_{5}$N was detected towards 35. These results are counter to the expectation that long chain cyanopolyynes, such as HC$_{5}$N, are not typically found in hot molecular cores, unlike their shorter chain counterpart HC$_{3}$N. However it is consistent with recent models which suggest HC$_{5}$N may exist for a limited period during the evolution of hot molecular cores.

description: In this study, β-CD-Ti4+-Fe3O4 and β-CD-Fe3O4-Ti4+ composites were prepared as novel, highly efficient and magnetically recoverable catalysts. The structures of these two composites were characterized by FT-IR, XRD, SEM, EDS, VSM, and TGA techniques. Their performance was also studied through the one-pot three-component synthesis of bis(indolyl)methane and benzo[a]xanthen-11-one derivatives. The reactions were carried out under solvent-free conditions, and the catalysts were easily recovered using an outside magnet. The products were obtained in good to high yields. The catalytic efficiency of β-CD-Ti4+-Fe3O4 was compared to that of the β-CD-Fe3O4-Ti4+ composite. The result indicated that the catalytic activities of β-CD-Ti4+-Fe3O4 and β-CD-Fe3O4-Ti4+ are the same but the magnetic strength of β-CD-Ti4+-Fe3O4 is greater than that of the β-CD-Fe3O4-Ti4+ composite.

description: Calyxochaetus cilifemoratus species group
Diagnosis. The C. cilifemoratus species group is defined by males having fore tarsomere 1 very short (as in Fig. 41) and mid tarsus slender with tarsomere 2 having the basal one-third to one-half slightly swollen (in dorsal or ventral view) and bearing 3–4 fine sinuous anterior setae (as in Figs 45, 47–49). Males also have the mid tarsomere 1 with 1–2 fine sinuous anterior setae at apex and mid tarsomere 4 usually with a fine sinuous anterior seta at apex. This group includes the only species of Calyxochaetus with a posterior preapical seta on the hind femur (Fig. 54, males and females). Females have a relatively wide face that is wider than postpedicel width. Scutellum without distinct blue-violet reflections.
Remarks. Species in this group primarily occur in the shade of grasses, sedges, rushes and shrubs in otherwise open, moist habitats and I have collected specimens by sweeping the net close to ground between or through vegetation. The species of Calyxochaetus that occur at high elevations in western North America are found in this group.

description: A new Schiff base was prepared by the condensation between the sulfa drug sulfadiazine and 5-nitrovanilline to form 4-((4-hydroxy-3-methoxy-5-nitrobenzylidene) amino)-N-(pyrimidin-2-yl) benzene sulfonamide (5NVDA). Spectral studies have been performed to confirm the structure of the compound. Electronic structure of the compound was studied using DFT B3LYP/aug-cc-pVDZ level. Detailed potential energy distribution and vibrational assignments were made with the help of scaled simulated spectrum. UV spectra in DMSO medium showed a strong peak at 335 nm, which is in consistent with TDDFT simulations using CAM-B3LYP functional. Frontier orbitals were analyzed and found that the compound is easily polarizable, but stable. The compound was stabilized by extensive delolcaltaion of electrons. Durg likeness studies proved that this compound is an ideal candidate to be used as a drug and PASS studies showed that it shows binding to HIV RNA activity, which is confirmed by molecular docking studies with docking score of −8.4 kcal/mol.

description: Supervised learning in a binary perceptron is able to classify an extensive number of random patterns by a proper assignment of binary synaptic weights. However, to find such assignments in practice, is quite a nontrivial task. The relation between the weight space structure and the algorithmic hardness has not yet been fully understood. To this end, we analytically derive the Franz-Parisi potential for the binary preceptron problem, by starting from an equilibrium solution of weights and exploring the weight space structure around it. Our result reveals the geometrical organization of the weight space\textemdash the weight space is composed of isolated solutions, rather than clusters of exponentially many close-by solutions. The point-like clusters far apart from each other in the weight space explain the previously observed glassy behavior of stochastic local search heuristics.

description: In this work, a novel pyridinium-based dicationic organic salt, [H2-BiPyr][ClO4]2, was easily prepared and characterized by FT-IR and NMR spectroscopy. After characterization, it was used as the catalyst in a one-pot multi-component reaction of aromatic aldehydes, ethyl acetoacetate and hydroxylamine hydrochloride under aqueous conditions at reflux temperature leading to the formation of 3-methyl-4-arylmethylene isoxazole-5(4H)-one derivatives.

description: The present study carried out in the first months of 2021 on a limited number of patients (10) is aimed at understanding how much the contagion - vaccine - affect the formation of antibodies but above all how active the so-called immunological memory remains in particular the B lymphocytes memory (CD 19 + / CD 27 +) During the study, by chance, there was a case of patient (7) with very high values of memory B lymphocytes affected by left parietal cerebral hemorrhage (atypical site) after three months of Pfizer-BioNTech vaccination. The study shows that the immune response is truly unique, in any case the contagion and healing immunize in general much more both as regards the antibodies and above all the b lymphocytes memory of any type of vaccination whether 1 - 2 - 3 or more doses are administered.

description: The time-dependent surface flux method developed for the description of electronic spectra [L. Tao and A. Scrinzi, New J. Phys. 14, 013021 (2012); A. Scrinzi, New J. Phys. 14, 085008 (2012)] is extended to treat dissociation and dissociative ionization processes of H2+ interacting with strong laser pulses. By dividing the simulation volume into proper spatial regions associated with the individual reaction channels and monitoring the probability flux, the joint energy spectrum for the dissociative ionization process and the energy spectrum for dissociation is obtained. The methodology is illustrated by solving the time-dependent Schrödinger equation (TDSE) for a collinear one-dimensional model of H2+ with electronic and nuclear motions treated exactly and validated by comparison with published results for dissociative ionization. The results for dissociation are qualitatively explained by analysis based on dressed diabatic Floquet potential energy curves, and the method is used to investigate the breakdown of the two-surface model.

description: The ${\rm H_2NC}$ radical is the high-energy metastable isomer of ${\rm H_2CN}$ radical, which has been recently detected for the first time in the interstellar medium towards a handful of cold galactic sources, besides a warm galaxy in front of the PKS 1830-211 quasar. These detections have shown that the ${\rm H_2CN}$/${\rm H_2NC}$ isomeric ratio, likewise the HCN/HNC ratio, might increase with the kinetic temperature ($T_{\rm kin}$), but the shortage of them in warm sources still prevents us to confirm this hypothesis and shed light about their chemistry. In this work, we present the first detection of ${\rm H_2CN}$ and ${\rm H_2NC}$ towards a warm galactic source, the G+0.693-0.027 molecular cloud (with $T_{\rm kin} > 70 \, {\rm K}$), using IRAM 30m observations. We have detected multiple hyperfine components of the $N_{K_\text{a}K_\text{c}} = 1_{01} - 0_{00}$ and $2_{02} - 1_{01}$ transitions. We derived molecular abundances with respect to ${\rm H_2}$ of (6.8$\pm$1.3)$\times 10^{-11}$ for ${\rm H_2CN}$ and of (3.1$\pm$0.7)$\times 10^{-11}$ for ${\rm H_2NC}$, and a ${\rm H_2CN}$/${\rm H_2NC}$ abundance ratio of 2.2$\pm$0.5. These detections confirm that the ${\rm H_2CN}$/${\rm H_2NC}$ ratio is $\gtrsim$2 for sources with $T_{\rm kin} > 70 \, {\rm K}$, larger than the $\sim$1 ratios previously found in colder cores ($T_{\rm kin}\sim10 \, {\rm K}$). This isomeric ratio dependence with temperature cannot be fully explained with the currently proposed gas-phase formation and destruction pathways. Grain surface reactions, including the ${\rm H_2NC} \rightarrow {\rm H_2CN}$ isomerization, deserve consideration to explain the higher isomeric ratios and ${\rm H_2CN}$ abundances observed in warm sources, where the molecules can be desorbed into the gas phase through thermal and/or shock-induced mechanisms.

On topological upper-bounds on the number of small cuspidal eigenvalues

Publisher: name: arXiv

Subjects: subject: Differential Geometry (math.DG)

description: Let $S$ be a noncompact, finite area hyperbolic surface of type $(g, n)$. Let $Δ_S$ denote the Laplace operator on $S$. As $S$ varies over the {\it moduli space} ${\mathcal{M}_{g, n}}$ of finite area hyperbolic surfaces of type $(g, n)$, we study, adapting methods of Lizhen Ji \cite{Ji} and Scott Wolpert \cite{Wo}, the behavior of {\it small cuspidal eigenpairs} of $Δ_S$. In Theorem 2 we describe limiting behavior of these eigenpairs on surfaces ${S_m} \in {\mathcal{M}_{g, n}}$ when $({S_m})$ converges to a point in $\overline{\mathcal{M}_{g, n}}$. Then we consider the $i$-th {\it cuspidal eigenvalue}, ${λ^c_i}(S)$, of $S \in {\mathcal{M}_{g, n}}$. Since {\it non-cuspidal} eigenfunctions ({\it residual eigenfunctions} or {\it generalized eigenfunctions}) may converge to cuspidal eigenfunctions, it is not known if ${λ^c_i}(S)$ is a continuous function. However, applying Theorem 2 we prove that, for all $k \geq 2g-2$, the sets $${{\mathcal{C}_{g, n}^{\frac{1}{4}}}}(k)= \{ S \in {\mathcal{M}_{g, n}}: {λ_k^c}(S) > \frac{1}{4} \}$$ are open and contain a neighborhood of ${\cup_{i=1}^n}{\mathcal{M}_{0, 3}} \cup {\mathcal{M}_{g-1, 2}}$ in $\overline{\mathcal{M}_{g, n}}$. Moreover, using topological properties of nodal sets of {\it small eigenfunctions} from \cite{O}, we show that ${{\mathcal{C}_{g, n}^{\frac{1}{4}}}}(2g-1)$ contains a neighborhood of ${\mathcal{M}_{0, n+1}} \cup {\mathcal{M}_{g, 1}}$ in $\overline{\mathcal{M}_{g, n}}$. These results provide evidence in support of a conjecture of Otal-Rosas \cite{O-R}.

Tensile Fracture of Welded Polymer Interfaces: Miscibility, Entanglements and Crazing

description: Large-scale molecular simulations are performed to investigate tensile failure of polymer interfaces as a function of welding time $t$. Changes in the tensile stress, mode of failure and interfacial fracture energy $G_I$ are correlated to changes in the interfacial entanglements as determined from Primitive Path Analysis. Bulk polymers fail through craze formation, followed by craze breakdown through chain scission. At small $t$ welded interfaces are not strong enough to support craze formation and fail at small strains through chain pullout at the interface. Once chains have formed an average of about one entanglement across the interface, a stable craze is formed throughout the sample. The failure stress of the craze rises with welding time and the mode of craze breakdown changes from chain pullout to chain scission as the interface approaches bulk strength. The interfacial fracture energy $G_I$ is calculated by coupling the simulation results to a continuum fracture mechanics model. As in experiment, $G_I$ increases as $t^{1/2}$ before saturating at the average bulk fracture energy $G_b$. As in previous simulations of shear strength, saturation coincides with the recovery of the bulk entanglement density. Before saturation, $G_I$ is proportional to the areal density of interfacial entanglements. Immiscibiltiy limits interdiffusion and thus suppresses entanglements at the interface. Even small degrees of immisciblity reduce interfacial entanglements enough that failure occurs by chain pullout and $G_I \ll G_b$.

description: In continuance of search for new compounds we report herein the expedient and optimized synthesis of a series of N-(4-substituted phenyl)-7-hydroxy-4-methyl-2-oxoquinoline-1(2H)-carbothioamides (5a-g) in good yields. The anticancer and antioxidant activities were determined as per the standard protocol. Nearly 5 dozens of cancer cell lines derived from nine different panels are used in the study and anticancer activity was calculated as growth percents (GPs) and percent growth inhibitions (%GIs). The molecular docking simulation against one of the potential targets i.e., epidermal growth factor receptor (EGFR) was done to find the putative approach of action of the title compounds 5a-g. N-(4-Nitrophenyl)-7-hydroxy-4-methyl-2-oxoquinoline-1(2H)-carbothioamides (5b) showed the most promising anticancer activity with higher sensitivity against UO-31, HOP-92, CAKI-1, LOX IMVI and T-47D with GPs of 66.65, 72.63, 85.80, 86.11, and 86.96 respectively. The compound 5b exhibited antioxidant activity with an IC50 value of 15.21 ± 1.52 µM. The molecular docking simulation showed an efficient binding of compound 5b against the activity site of EGFR with two H-bond interactions with the residues Gln791 and Thr854, a π-π stacking and a π-cationic interaction with the residue Phe856, while a salt bridge interaction with the residue Lys745.

description: We present herein galaxy number counts of the nine bands in the 2-24 micron range on the basis of the AKARI North Ecliptic Pole (NEP) surveys. The number counts are derived from NEP-deep and NEP-wide surveys, which cover areas of 0.5 and 5.8 deg2, respectively. To produce reliable number counts, the sources were extracted from recently updated images. Completeness and difference between observed and intrinsic magnitudes were corrected by Monte Carlo simulation. Stellar counts were subtracted by using the stellar fraction estimated from optical data. The resultant source counts are given down to the 80% completeness limit; 0.18, 0.16, 0.10, 0.05, 0.06, 0.10, 0.15, 0.16, and 0.44 mJy in the 2.4, 3.2, 4.1, 7, 9, 11, 15, 18 and 24 um bands, respectively. On the bright side of all bands, the count distribution is flat, consistent with the Euclidean Universe, while on the faint side, the counts deviate, suggesting that the galaxy population of the distant universe is evolving. These results are generally consistent with previous galaxy counts in similar wavebands. We also compare our counts with evolutionary models and find them in good agreements. By integrating the models down to the 80% completeness limits, we calculate that the AKARI NEP-survey revolves 20%-50% of the cosmic infrared background, depending on the wavebands.
