description: We have analyzed the kinematics of 9750 OB2 stars with proper motions and parallaxes selected by Xu et al. from the Gaia EDR3 catalogue. The relative parallax errors for these stars do not exceed 10\%. Based on the entire sample of stars, we have found the velocities $(U,V)_\odot=(7.17,7.37)\pm(0.16,0.24)$ km s$^{-1}$ and the components of the angular velocity of Galactic rotation: $Ω_0 =29.700\pm0.076$ km s$^{-1}$ kpc$^{-1}$, $Ω^{'}_0 =-4.008\pm0.022$ km s$^{-1}$ kpc$^{-2}$, and $Ω^{''}_0 = 0.671\pm0.011$ km s$^{-1}$ kpc$^{-3}$, where the linear rotation velocity of the Galaxy at the solar distance is $V_0=240.6\pm3.0$ km s$^{-1}$ for the adopted $R_0=8.1\pm0.1$ kpc. There are 1812 OB2 stars with measured line-of-sight velocities, and the space velocities $V_R$ and $ΔV_{circ}$ have been calculated from them. Based on a spectral analysis independently for the radial and residual tangential velocities, we have obtained the following estimates: $f_R=4.8\pm0.7$ km s$^{-1}$, $f_θ=4.1\pm0.9$ km s$^{-1}$, $λ_R=2.1\pm0.2$ kpc, $λ_θ=2.2\pm0.4$ kpc, $(χ_\odot)_R=-116\pm12^\circ$, and $(χ_\odot)_θ=-156\pm14^\circ$ for the adopted four-armed ($m = 4$) spiral pattern. Thus, both velocity perturbation amplitudes are nonzero at a high significance level.

description: Pomacea canaliculata is listed among the world’s 100 worst invasive species, for threatening rice production and wetland biodiversity. We compared morphological and genetic characteristics of the 14 P. canaliculata geographic populations in mainland China to explore morphological differentiation in relation to geographical isolation and climate effects. The results showed that the average shell height, standing height and body width of P. canaliculata samples were 29.39, 18.52 and 19.91 mm. Morphological characteristics were significantly different among the P. canaliculata geographic populations. The changes in morphological characteristics fitted a linear model. Geometric measurement showed a significant difference in centroid size among the 14 populations. Canonical variates analysis revealed three distinct clusters and that four geographic populations were independent in shell shape variation. Mahalanobis distances showed significant relationships among all populations except Pingtang vs. Zhangzhou. The cumulative contribution of PC1, PC2 and PC3 in principal component analysis reached 80%. The overall identification accuracy was 97%. However, only 3.9% of pairwise Coefficient of Difference values exceeded 1.28. The difference in morphological traits did not conform to the isolation-by-distance model. The P. canaliculata phenotype was closely related to local climatic factors. In summary, the adaptation of Chinese P. canaliculata populations is ongoing.

description: Acute myeloblastic leukaemia (AML) is a type of cancer affecting the cells of the bone marrow, preventing the normal production of blood cells. When a person is affected, the prognosis is poor. Whether due to late diagnosis or lack of more specific treatments, the cure rate is low.1 5-Aza-2′-Deoxycytidine (Decitabine, AzadC or DAC) is one of this drug, and like most of them it has important drawbacks. This molecule is a nucleoside analogue drug. When incorporated into DNA, it inhibits DNA methyltransferases (DNMTs) and causes the level of DNA methylation to fall, leading to the reactivation of tumour suppressor genes.2,3 However, AzadC is used as a remedy of last resort due to significant side effects, probably because of spontaneous hydrolysis of the molecule and yet we achieved to obtain a stable derivative of this epigenetic medicine. By modifying the ribose of the base into a carbocycle (cAzadC or cDAC), we preserved the original mode of action in cellulo while obtaining a hydrolytically stable compound.4 The current work contributes to map the overall the metabolization pathway of cAzadC in diverse cell lines and organs. The investigation of the proteins interacting with our compound allows its progressive structural optimisation to overcome potential resistance and obtain a drug for AML that is both, specific and stable.

Diagnosis of the P. atra species group
Within the Palaearctic, two well defined species groups can be separated: the P. atra species group, recognized in both sexes by the only slightly microtrichose and therefore clearly shiny face below the antenna, and by bluishblack and shiny thorax and abdomen, while the P. innupta species group is recognized in both sexes by the heavily microtrichose and therefore clearly dull face below the antenna, by bronze-brown color of thorax and abdomen, and by the medially dull terga in males. The P. atra group consists of the following species: Psilota anthracina, Psilota atra (Fallén), Psilota exilistyla Smit et Vujić, Psilota kroshka Mutin, and Psilota nana Smit et Vujić.

description: The results of investigation of bulk GaAs photoluminescence are presented taken from near-surface layers of different thicknesses using for excitation the light with the wavelengths which are close but some greater than the excitonic absorption resonances (so-called bulk photoexcitation). Only the excitonic and band-edge luminescence is seen under the interband excitation, while under the bulk excitation, the spectra are much more informative. The interband excited spectra of all the samples investigated in the present work are practically identical, whereas the bulk excited PL spectra are different for different samples and excitation depths and provide the information on the deep-level point defect composition of the bulk materials.

According to Bezark & Santos-Silva (2016): “ Rashelapso morrisoni sp. nov. is somewhat aberrant in the genus by the lower eye lobes in male distinctly apart, and by the procoxal cavities distinctly opened behind.” Actually, these two features are present in Giesberteclipta, as well as the well-marked humeral carina. Consequently, R. morrisoni is transferred to Giesberteclipta.

description: Alkylphospholipids are a novel class of antineoplastic drugs showing remarkable therapeutic potential. Among them, erufosine (EPC3) is a promising drug for the treatment of several types of tumors. While EPC3 is supposed to exert its function by interacting with lipid membranes, the exact molecular mechanisms involved are not known yet. In this work, we applied a combination of several fluorescence microscopy and analytical chemistry approaches (i.e., scanning fluorescence correlation spectroscopy, line-scan fluorescence correlation spectroscopy, generalized polarization imaging, as well as thin layer and gas chromatography) to quantify the effect of EPC3 in biophysical models of the plasma membrane, as well as in cancer cell lines. Our results indicate that EPC3 affects lipid–lipid interactions in cellular membranes by decreasing lipid packing and increasing membrane disorder and fluidity. As a consequence of these alterations in the lateral organization of lipid bilayers, the diffusive dynamics of membrane proteins are also significantly increased. Taken together, these findings suggest that the mechanism of action of EPC3 could be linked to its effects on fundamental biophysical properties of lipid membranes, as well as on lipid metabolism in cancer cells.

title: Geometrical Bodies as Material Forms: Luca Pacioli's 'Summa', 'Divina Proportione', 'Euclid's Elements', and the Architecture of the Late Fifteenth-Early Sixteenth Century
Creators: name: Damiani, Giacomo
Publisher: name: University of Kent
Year: 2022

description: This thesis considers how and why geometrical bodies were regarded as exemplary forms in Luca Pacioli's works and by which means these were applied to architecture, and compares Pacioli's position with those of other architectural theorists. To accomplish this, it relies on an understanding of human visuality coherent with the latest research in the psychology and philosophy of perception. Pacioli was a lecturer in mathematics, was exceptionally well-placed in some of the most learned courtly environments and was very receptive to philosophical and mathematical trends. He was also very able when these had to be summarised or developed in his works. Pacioli's works stand at the intersection of the theoretical and practical knowledge of the late fifteenth and early sixteenth centuries. These are therefore extraordinary documents with which to trace the interrelation of philosophical, mathematical, and architectural arguments and consider the work of the practitioners with whom Pacioli interacted. Lastly, this thesis examines Pacioli's arguments on geometrical bodies and their application to the architecture of Donato Bramante, in their philosophical and theoretical contexts. Ultimately, the contextual analysis of Pacioli's arguments and Bramante's innovative design process clarifies not only their inherent correlations, but also their relevance to present-day approaches to the formal, visual, and spatial properties of architecture.

description: Let A(x) be a holomorphic family of bounded self-adjoint operators on a separable Hilbert space H and let A(x)_n be the orthogonal compressions of A(x) to the span of first n elements of an orthonormal basis of H. The problem considered here is to approximate the spectrum of A(x) using the sequence of eigenvalues of A(x)_n. We show that the bounds of the essential spectrum and the discrete spectral values outside the bounds of essential spectrum of A(x) can be approximated uniformly on all compact subsets by the sequence of eigenvalue functions of A(x)_n. The known results for a bounded selfadjoint operator, are translated into the case of a holomorphic family of operators. Also an attempt is made to predict the existence of spectral gaps that may occur between the bounds of essential spectrum of A(0) = A and study the effect of holomorphic perturbation of operators in the prediction of spectral gaps. As an example, gap issues of some block Toeplitz-Laurent operators are discussed. The pure linear algebraic approach is the main advantage of the results here.

description: We report on a theoretical study about the magneto-dipolar coupling and synchronization between two vortex-based spin-torque nano-oscillators. In this work we study the dependence of the coupling efficiency on the relative magnetization parameters of the vortices in the system. For that purpose, we combine micromagnetic simulations, Thiele equation approach, and analytical macro-dipole approximation model to identify the optimized configuration for achieving phase-locking between neighboring oscillators. Notably, we compare vortices configurations with parallel (P) polarities and with opposite (AP) polarities. We demonstrate that the AP core configuration exhibits a coupling strength about three times larger than in the P core configuration.

description: Composite adaptive control (CAC) that integrates direct and indirect adaptive control techniques can achieve smaller tracking errors and faster parameter convergence compared with direct and indirect adaptive control techniques. However, the condition of persistent excitation (PE) still has to be satisfied to guarantee parameter convergence in CAC. This paper proposes a novel model reference composite learning control (MRCLC) strategy for a class of affine nonlinear systems with parametric uncertainties to guarantee parameter convergence without the PE condition. In the composite learning, an integral during a moving-time window is utilized to construct a prediction error, a linear filter is applied to alleviate the derivation of plant states, and both the tracking error and the prediction error are applied to update parametric estimates. It is proven that the closed-loop system achieves global exponential-like stability under interval excitation rather than PE of regression functions. The effectiveness of the proposed MRCLC has been verified by the application to an inverted pendulum control problem.

The development of nucleic acid probes targeting DNA, such as triplex-forming oligonucleotides (TFOs), offers an alternative strategy whereby gene expression is directly inhibited at the genomic level. Here, we present a click chemistry strategy for the generation of a new class of cis-platinum(II)-TFO hybrid biomaterial that possess DNA binding and crosslinking activity.

description: $ \newcommand{\R}{\mathbb{R}} \newcommand{\lat}{\mathcal{L}} $We prove a conjecture due to Dadush, showing that if $\lat \subset \R^n$ is a lattice such that $\det(\lat') \ge 1$ for all sublattices $\lat' \subseteq \lat$, then \[ \sum_{\vec y \in \lat} e^{-πt^2 \|\vec y\|^2} \le 3/2 \; , \] where $t := 10(\log n + 2)$. From this we derive bounds on the number of short lattice vectors, which can be viewed as a partial converse to Minkowski's celebrated first theorem. We also derive a bound on the covering radius.

description: To make progress in cartilage repair it is essential to optimize protocols for two-dimensional cell expansion. Chondrocytes and SDSCs are promising cell sources for cartilage repair. We previously observed that priming with a specific growth factor cocktail (1 ng/mL transforming growth factor-β1, 5 ng/mL basic fibroblast growth factor, and 10 ng/mL platelet-derived growth factor-BB) in two-dimensional culture, led to significant improvement in mechanical and biochemical properties of synovium-derived stem cell (SDSC)-seeded constructs. The current study assessed the effect of growth factor priming on the proteome of canine chondrocytes and SDSCs. In particular, growth factor priming modulated the proteins associated with the extracellular matrix in two-dimensional cultures of chondrocytes and SDSCs, inducing a partial dedifferentiation of chondrocytes (most proteins associated with cartilage were down-regulated in primed chondrocytes) and a partial differentiation of SDSCs (some collagen-related proteins were up-regulated in primed SDSCs). However, when chondrocytes and SDSCs were grown in pellet culture, growth factor-primed cells maintained their chondrogenic potential with respect to glycosaminoglycan and collagen production. In conclusion, the strength of the label-free proteomics technique is that it allows for the determination of changes in components of the extracellular matrix proteome in chondrocytes and SDSCs in response to growth factor priming, which could help in future tissue engineering strategies.

description: Background
During osteoarthritis and following surgical procedures, the environment of the knee is rich in proinflammatory cytokines such as IL-1. Introduction of tissue-engineered cartilage constructs to a chemically harsh milieu may limit the functionality of the implanted tissue over long periods. A chemical preconditioning scheme (application of low doses of IL-1) was tested as a method to prepare developing engineered tissue to withstand exposure to a higher concentration of the cytokine, known to elicit proteolysis as well as rapid degeneration of cartilage.

Methods
Using an established juvenile bovine model system, engineered cartilage was preconditioned with low doses of IL-1α (0.1 ng/mL, 0.5 ng/mL, and 1.0 ng/mL) for 7 days before exposure to an insult dose (10 ng/mL). The time frame over which this protection is afforded was investigated by altering the amount of time between preconditioning and insult as well as the time following insult. To explore a potential mechanism for this protection, one set of constructs was preconditioned with CoCl2, a chemical inducer of hypoxia, before exposure to the IL-1α insult. Finally, we examined the translation of this preconditioning method to extend to clinically relevant adult, passaged chondrocytes from a preclinical canine model.

Results
Low doses of IL-1α (0.1 ng/mL and 0.5 ng/mL) protected against subsequent catabolic degradation by cytokine insult, preserving mechanical stiffness and biochemical composition. Regardless of amount of time between preconditioning scheme and insult, protection was afforded. In a similar manner, preconditioning with CoCl2 similarly allowed for mediation of catabolic damage by IL-1α. The effects of preconditioning on clinically relevant adult, passaged chondrocytes from a preclinical canine model followed the same trends with low-dose IL-1β offering variable protection against insult.

Conclusions
Chemical preconditioning schemes have the ability to protect engineered cartilage constructs from IL-1-induced catabolic degradation, offering potential modalities for therapeutic treatments.

description: The purpose of this article is to develop a technique to estimate certain bounds for entropy numbers of diagonal operator on spaces of p-summable sequences for finite p greater than 1. The approximation method we develop in this direction works for a very general class of operators between Banach spaces, in particular reflexive spaces. As a consequence of this technique we also obtain that the entropy number of a bounded linear operator T between two separable Hilbert spaces is equal to the entropy number of the adjoint of T. This gives a complete answer to the question posed by B. Carl [4] in the setting of separable Hilbert spaces.

description: Recent evidence has shown potential cognitive benefits in Parkinson’s disease from restoring neuro- transmitter deficits including noradrenergic and serotonergic transmission. Here, we study global and regional brain network organization using task-free imaging, which minimizes performance confounds and the bias towards predetermined networks. Thirty-three patients with idiopathic Parkinson’s disease were studied three times in a double-blinded, placebo-controlled crossover design, following placebo, 40mg oral atomoxetine or 30mg oral citalopram. Seventy-six controls were scanned without medication to provide normative data. Relative to controls, patients on placebo had executive impairments, which was reflected in dysfunctional network dynamics in terms of reduced clustering coefficient, hub degree and hub centrality. In patients, atomoxetine improved fluency in proportion to plasma concentration (P=0.006, r2=0.24), and improved response inhibition in proportion to increased hub Eigen centrality (P=0.044, r2=0.14). Citalopram did not improve fluency or inhibitory control, but its influence on network integration and efficiency depended on disease severity: clustering (P=0.01, r2=0.22), modularity (P=0.043, r2=0.14) and path length (P=0.006, r2=0.25) increased in patients with milder forms of Parkinson’s disease, but decreased in patients with more advanced disease (UPDRSIII>30). This study supports the use of task-free imaging of brain networks in translational pharmacology of neurodegenerative disorders. We propose that hub connectivity contributes to cognitive performance in Parkinson’s disease, and that noradrenergic treatment strategies can partially restore the neural systems supporting executive function.robinborchert@gmail.com

description: In analogy with the Gopakumar-Vafa conjecture on CY 3-folds, Klemm and Pandharipande defined GV type invariants on Calabi-Yau 4-folds using Gromov-Witten theory and conjectured their integrality. In this paper, we propose a sheaf-theoretic interpretation of their genus zero invariants using Donaldson-Thomas theory on CY 4-folds. More specifically, we conjecture genus zero GV type invariants are $\mathrm{DT_{4}}$ invariants for one-dimensional stable sheaves on CY 4-folds. Some examples are computed for both compact and non-compact CY 4-folds to support our conjectures. We also propose an equivariant version of the conjectures for local curves and verify them in certain cases.

Aspects of the decoherence in high spin environments: Breakdown of the mean-field approximation

description: The study of the decoherence of qubits in spin systems is almost restricted to environments whose constituents are spin-$\frac{1}{2}$ particles. In this paper we consider environments that are composed of particles of higher spin, and we investigate the consequences on the dynamics of a qubit coupled to such baths via Heisenberg $XY$ and Ising interactions. It is shown that while the short time decay in both cases gets faster as the magnitude of the spin increases, the asymptotic behavior exhibits an improvement of the suppression of the decoherence when the coupling is through Heisenberg $XY$ interactions. In the case of a transverse Ising model, we find that the mean field approximation breaks down for high values of the spin.

description: Background: Respiratory protective equipment recommended in the UK for healthcare workers (HCWs) caring for patients with COVID-19 comprises a fluid-resistant surgical mask (FRSM), except in the context of aerosol generating procedures (AGPs). We previously demonstrated frequent pauci- and asymptomatic severe acute respiratory syndrome coronavirus 2 infection HCWs during the first wave of the COVID-19 pandemic in the UK, using a comprehensive PCR-based HCW screening programme (Rivett et al., 2020; Jones et al., 2020). Methods: Here, we use observational data and mathematical modelling to analyse infection rates amongst HCWs working on 'red' (coronavirus disease 2019, COVID-19) and 'green' (non-COVID-19) wards during the second wave of the pandemic, before and after the substitution of filtering face piece 3 (FFP3) respirators for FRSMs. Results: Whilst using FRSMs, HCWs working on red wards faced an approximately 31-fold (and at least fivefold) increased risk of direct, ward-based infection. Conversely, after changing to FFP3 respirators, this risk was significantly reduced (52-100% protection). Conclusions: FFP3 respirators may therefore provide more effective protection than FRSMs for HCWs caring for patients with COVID-19, whether or not AGPs are undertaken.
