description: We study braneworld models in the presence of scalar field in a five-dimensional geometry with a single extra dimension of infinite extent, with gravity modified to include a function of the Ricci scalar. We develop a procedure that allows to obtain analytical solution for the braneworld configuration in a diversity of models, in the much harder case where the Ricci scalar is non constant quantity.

Quantitative Analysis of Membrane Trafficking in Regulation of Cdc42 Polarity

description: Vesicle delivery of Cdc42 has been proposed as an important mechanism for generating and maintaining Cdc42 polarity at the plasma membrane. This mechanism requires the density of Cdc42 on secretory vesicles to be equal to or higher than the plasma membrane polarity cap. Using a novel method to estimate Cdc42 levels on post-Golgi secretory vesicles in intact yeast cells, we: 1) determined that endocytosis plays an important role in Cdc42’s association with secretory vesicles 2) found that a GFP-tag placed on the N-terminus of Cdc42 negatively impacts this vesicle association and 3) quantified the surface densities of Cdc42 on post-Golgi vesicles which revealed that the vesicle density of Cdc42 is three times more dilute than that at the polarity cap. This work suggests that the immediate consequence of secretory vesicle fusion with the plasma membrane polarity cap is to dilute the local Cdc42 surface density. This provides strong support for the model in which vesicle trafficking acts to negatively regulate Cdc42 polarity on the cell surface while also providing a means to recycle Cdc42 between the cell surface and internal membrane locations.

4-Aminoquinoline compounds from the Spanish flu to COVID-19

Publisher: name: Torrens University Australia

Subjects: Molecular medicine

description: In 1918, quinine was used as one of the unscientifically based treatments against the H1N1 virus during the Spanish flu pandemic. Originally, quinine was extracted from the bark of Chinchona trees by South American natives of the Amazon forest, and it has been used to treat fever since the seventeenth century. The recent COVID-19 pandemic caused by Sars-Cov-2 infection has forced researchers to search for ways to prevent and treat this disease. Based on the antiviral potential of two 4-aminoquinoline compounds derived from quinine, known as chloroquine (CQ) and hydroxychloroquine (HCQ), clinical investigations for treating COVID-19 are being conducted worldwide. However, there are some discrepancies among the clinical trial outcomes.Thus, even after one hundred years of quinine use during the Spanish flu pandemic, the antiviral properties promoted by 4-aminoquinoline compounds remain unclear. The underlying molecular mechanisms by which CQ and HCQ inhibit viral replication open up the possibility of developing novel analogs of these drugs to combat COVID-19 and other viruses.

description: Weyl semi-metal is the three dimensional analog of graphene. According to the quantum field theory, the appearance of Weyl points near the Fermi level will cause novel transport phenomena related to chiral anomaly. In the present paper, we report the first experimental evidence for the long-anticipated negative magneto-resistance generated by the chiral anomaly in a newly predicted time-reversal invariant Weyl semi-metal material TaAs. Clear Shubnikov de Haas oscillations (SdH) have been detected starting from very weak magnetic field. Analysis of the SdH peaks gives the Berry phase accumulated along the cyclotron orbits to be π, indicating the existence of Weyl points.

description: Long-range quantum lattice systems often exhibit drastically different behavior than their short-range counterparts. In particular, because they do not satisfy the conditions for the Lieb-Robinson theorem, they need not have an emergent relativistic structure in the form of a light cone. Adopting a field-theoretic approach, we study the one-dimensional transverse-field Ising model with long-range interactions, and a fermionic model with long-range hopping and pairing terms, explore their critical and near-critical behavior, and characterize their response to local perturbations. We deduce the dynamic critical exponent, up to the two-loop order within the renormalization group theory, which we then use to characterize the emergent causal behavior. We show that beyond a critical value of the power-law exponent of the long-range couplings, the dynamics effectively becomes relativistic. Various other critical exponents describing correlations in the ground state, as well as deviations from a linear causal cone, are deduced for a wide range of the power-law exponent.

description: We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of 182 stellar targets along the line of sight to the newly-discovered `ultrafaint' object Reticulum 2 (Ret 2). For 38 of these targets, the spectra are sufficient to provide simultaneous estimates of line-of-sight velocity ($v_{\rm los}$, median random error $δ_{v_{\rm los}}=1.3$ km s$^{-1}$), effective temperature ($T_{\rm eff}$, $δ_{T_{\rm eff}}=464$ K), surface gravity ($\log g$, $δ_{\rm logg}=0.54$ dex) and iron abundance ([Fe/H], $δ_{\mathrm{[Fe/H]}}=0.45$ dex). We use these results to confirm 18 stars as members of Ret 2. From the member sample we estimate a velocity dispersion of $σ_{v_{\rm los}}=3.6_{-0.6}^{+0.9}$ km s$^{-1}$ about a mean of $\langle v_{\rm los}\rangle =64.8_{-1.0}^{+1.1}$ km s$^{-1}$ in the solar rest frame ($\sim -90.9$ km s$^{-1}$ in the Galactic rest frame), and a metallicity dispersion of $σ_{\rm [Fe/H]}=0.50_{-0.13}^{+0.17}$ dex about a mean of $\langle \mathrm{[Fe/H]} \rangle =-2.67_{-0.34}^{+0.34}$. These estimates marginalize over possible velocity and metallicity gradients, which are consistent with zero. Our results place Ret 2 on chemodynamical scaling relations followed by the Milky Way's dwarf-galactic satellites. Under assumptions of dynamic equilibrium and negligible contamination from binary stars---both of which must be checked with deeper imaging and repeat spectroscopic observations---the estimated velocity dispersion suggests a dynamical mass of $M(R_{\rm h})\approx 5R_{\rm h}σ_{v_{\rm los}}^2/(2G)=2.4_{-0.8}^{+1.3}\times 10^5$ $M_{\odot}$ enclosed within projected halflight radius $R_{\rm h}\sim 32$ pc, with mass-to-light ratio $\approx 2M(R_{\rm h})/L_{\rm V}=462_{-157}^{+264}$ in solar units.

Στόχος αυτής της εργασίας είναι η ανάλυση των επιδόσεων των χωρών στον τουρισμό συγκριτικά με τα αποτελέσματα που έχουν επιτευχθεί, λαμβάνοντας ωστόσο υπόψη και τους πόρους που έχουν χρησιμοποιηθεί. Αυτό επιτυγχάνεται με τη συλλογή δεδομένων σχετικά με τις επιδόσεις της κάθε χώρας (αφίξεις τουριστών, χρηματικά ποσά που εισπράχθηκαν κ.α.) με βάση όμως τις δαπάνες που πραγματοποιήθηκαν από την αντίστοιχη χώρα (πιθανή διαφήμιση του τουριστικού προϊόντος, κατασκευή ανάλογων υποδομών κ.α.). Κάθε χώρα η οποία αποτελεί και το τουριστικό προϊόν για να μπορεί να χαρακτηριστεί ανταγωνιστική και να προτιμάται έναντι των υπολοίπων, θα πρέπει να διαθέτει όσο το δυνατόν υψηλότερα επίπεδα βαθμολογιών στην παγκόσμια κατάταξη αξιολόγησης. Στο πλαίσιο αυτό ο δείκτης TTCI (Travel & Tourism Competitiveness Index) που δημοσιεύεται σε ετήσια βάση από το World Economic Forum υπολογίζει σε παγκόσμιο επίπεδο τη σειρά των χωρών από την πιο ανταγωνιστική έως την λιγότερο ανταγωνιστική, λαμβάνοντας υπόψη το σύνολο ιδιοτήτων και χαρακτηριστικών που εμφανίζει η εκάστοτε χώρα σε διάφορους τομείς. Στην παρούσα εργασία θα χρησιμοποιηθεί η μέθοδος DEA για να εξεταστεί η ανταγωνιστικότητα των τουριστικών προορισμών. Συγκεκριμένα, θα διερευνηθούν διαφορετικά μοντέλα DEA που δημιουργήθηκαν για το σκοπό της συγκεκριμένης εργασίας, ενώ τα αποτελέσματα θα συγκριθούν με την κατάταξη του δείκτη TTCI.

description: In many developing countries including those of sub-Saharan Africa care of the critically ill is poorly developed. We therefore sought to elucidate the characteristics and outcomes of critically ill patients to better define the burden of disease and identify strategies for improving care. We conducted a cross sectional observation study of patients admitted to the intensive care unit at Kamuzu Central Hospital in 2010. Demographic, patient characteristics, clinical specialty and outcome data was collected. There were 234 patients admitted during the study period. Older age and admission from trauma, general surgery or medical services were associated with increased mortality. The lowest mortality was among obstetrical and gynecologic patients. Use of the ventilator and transfusions were not associated with increased mortality. Head injured patients had the highest mortality rate among all diagnoses. Rationing of critical care resources using admitting diagnosis or scoring tools can maximize access to critical care services in resource-limited settings. Furthermore, improvements on critical care services will be central to future efforts at reducing surgical morbidity and mortality and improving outcomes in all critically ill patients.

description: Diamonds are very promising candidates for the neutron diagnostics in harsh environments such as fusion reactor. In the first place this is because of their radiation hardness, exceeding that of Silicon by an order of magnitude. Also, in comparison to the standard on-line neutron diagnostics (fission chambers, silicon based detectors, scintillators), diamonds are less sensitive to $γ$ rays, which represent a huge background in fusion devices. Finally, their low leakage current at high temperature suppresses the detector intrinsic noise. In this talk a CVD diamond based detector has been proposed for the measurement of the 14 MeV neutrons from D-T fusion reaction. The detector was arranged in a proton recoil telescope configuration, featuring a plastic converter in front of the sensitive volume in order to induce the (n,p) reaction. The segmentation of the sensitive volume, achieved by using two crystals, allowed to perform measurements in coincidence, which suppressed the neutron elastic scattering background. A preliminary prototype was assembled and tested at FNG (Frascati Neutron Generator, ENEA), showing promising results regarding efficiency and energy resolution.

description: Under the auspices of the Keck Institute for Space Studies at Caltech, we convened a group of Mars scientists and engineers, representing multiple academic institutions, NASA Centers, and commercial companies in March 2021 to address the challenge of revolutionizing access to the Mars surface. Following a 3-month summer study period where working groups addressed specific programmatic, cultural, and engineering challenges, we then convened a second workshop in September 2021. The report that follows represents the product of the
discussions.

We first outline why Mars—and particularly landed access to Mars—is a priority over the next decades of scientific exploration (Section 1). We then review the challenges to achieving increased numbers of missions accessing the Mars surface (Section 2) as well as near-term trends in the space sector that provide means to overcome these challenges (Section 3). We then describe the intertwined elements of the Frequent, Affordable, Bold (FAB) strategy to achieve access (Section 4). Finally, we discuss the means by which a FAB strategy can be implemented, developing similar sets of science mission types and employing a services model that fosters increasing commercial capabilities over a set of the mission types (Section 5).

description: Fluctuation and dissipation are by-products of coupling to the `environment.' The Caldeira-Leggett model, a successful paradigm of quantum Brownian motion, views the environment as a collection of harmonic oscillators linearly coupled to the system. However, symmetry considerations may forbid a linear coupling, e.g. for a neutral particle in quantum electrodynamics. We argue that nonlinear couplings can lead to a fundamentally different behavior. Specifically, we consider a heavy particle quadratically coupled to quantum fluctuations of the bath. In one dimension the particle undergoes anomalous diffusion, unfolding as a power-law distribution in space, reminiscent of Lévy flights. We suggest condensed matter analogs where similar effects may arise.

description: The output of the rotating shaft vigorously depends on the condition of a shaft. While deeming the perfection of a shaft, crack can be one of the major factors that need to emphasize on. Because of the mechanical design the shaft undergoes continuous stress while the engine is running. As the power of the engine escalated the stress on the shaft started increasing and perpetual running of engine in this condition causes failure resulting crack in the shaft. However, crack may propagate into 2 stages, at the beginning there is rising stress, change in the cross section or some other factors, for instance-fretting, porosity, inclusion etc generates the crack. Afterwards, if the machine left running with the first condition the discontinuity started increasing because of repeated stress imposed on the rotating shaft. Crack present in the shaft can obstruct the performances of the shaft enormously and at a certain stage it causes failure or loss of efficiency. Thus, it’s important to identify the crack within the shaft at the beginning of its generation. In this paper the cracked behavior of a shaft is identified by vibrating the shaft transversely. Different types of cracked specimen are examined, and data are compared with the behavior of specimen without having crack.

description: Oriented circular cylinders in an opaque medium are used to represent certain microstructural objects in steel. The opaque medium is sliced parallel to the cylinder axes of symmetry and the cut-plane contains the observable rectangular profiles of the cylinders. A one-to-one relation between the joint density of the squared radius and height of the 3D cylinders and the joint density of the squared half-width and height of the observable 2D rectangles is established. We propose a nonparametric estimation procedure to estimate the distributions and expectations of various quantities of interest, such as the cylinder radius, height, aspect ratio, surface area and volume from the observed 2D rectangle widths and heights. Also, the covariance between the radius and height of a cylinder is estimated. The asymptotic behavior of these estimators is established to yield point-wise confidence intervals for the expectations and point-wise confidence sets for the distributions of the quantities of interest. Many of these quantities can be linked to the mechanical properties of the material, and are, therefore, useful for industry. We illustrate the mathematical model and estimation procedures using a banded microstructure for which nearly 90 \textmu m of depth have been observed via serial sectioning.

description: We apply the framework of tempered fractional calculus to investigate the spatial dispersion of elastic waves in a one-dimensional elastic bar characterized by range-dependent nonlocal interactions. The measure of the interaction is given by the attenuation kernel present in the constitutive stress-strain relation of the bar, which follows from the Kröner-Eringen's model of nonlocal elasticity. We employ a fractional power-law attenuation kernel and spatially temper it, to make the model physically valid and mathematically consistent. The spatial dispersion relation is derived, but it turns out to be difficult to solve, both analytically and numerically. Consequently, we use numerical techniques to extract the real and imaginary parts of the complex wavenumber for a wide range of frequency values. From the dispersion plots, it is found that the phase velocity dispersion of elastic waves in the tempered nonlocal elastic bar is similar to that from the time-fractional Zener model. Further, we also examine the unusual attenuation pattern obtained for the elastic wave propagation in the bar.

Power-law tails in probability density functions of molecular cloud column density

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Power-law tails are often seen in probability density functions (PDFs) of molecular cloud column densities, and have been attributed to the effect of gravity. We show that extinction PDFs of a sample of five molecular clouds obtained at a few tenths of a parsec resolution, probing extinctions up to A$_{\mathrm{V}}$ $\sim$ 10 magnitudes, are very well described by lognormal functions provided that the field selection is tightly constrained to the cold, molecular zone and that noise and foreground contamination are appropriately accounted for. In general, field selections that incorporate warm, diffuse material in addition to the cold, molecular material will display apparent core+tail PDFs. The apparent tail, however, is best understood as the high extinction part of a lognormal PDF arising from the cold, molecular part of the cloud. We also describe the effects of noise and foreground/background contamination on the PDF structure, and show that these can, if not appropriately accounted for, induce spurious tails or amplify any that are truly present.

description: Cell motility and tissue morphogenesis depend crucially on the dynamic remodelling of actomyosin networks. An actomyosin network consists of an actin polymer network connected by crosslinker proteins and motor protein myosins that generate internal stresses on the network. A recent discovery shows that for a range of experimental parameters, actomyosin networks contract to clusters with a power-law size distribution [Alvarado J. et al. (2013) Nature Physics 9 591]. Here, we argue that actomyosin networks can exhibit robust critical signature without fine-tuning because the dynamics of the system can be mapped onto a modified version of percolation with trapping (PT), which is known to show critical behaviour belonging to the static percolation universality class without the need of fine-tuning of a control parameter. We further employ our PT model to generate experimentally testable predictions.

description: In the context of an Intermittent preventive treatment (IPTp) trial for pregnant women in Malawi, P. falci-parum samples from 85 women at enrollment and 35 women at delivery were genotyped for mutations associated with sulfadoxine-pyrimethamine resistance. The prevalence of the highly resistant haplotype with mutations at codons 51 and 108 of dihydrofolate reductase (dhfr) and codons 437 and 540 of dihydropteroate synthase (dhps) increased from 81% at enrollment to 100% at delivery (p=0.01). Pregnant women who were smear-positive at enrollment were more likely to have P. falciparum parasitemia at delivery. These results lend support to concerns that IPTp use may lead to increased drug resistance in pregnant women during pregnancy and emphasize the importance of screening pregnant women for malaria parasites in areas with prevalent SP resistance even when they are already on IPTp.

Are self-recognizing Thymus lymphocytes more central than people consider?

description: Antigen presentation to T-cells with MHC I and II is a young science. It has not been explored that long. Younger than antibodies, since those were observable more easy. And since antibodies clearly bind to non-self, there would be a priori prejudice to assume T-cell receptors did as well. It is known that self-antigen are fewer than non-self. This is self-evident. What is not as intuitive is that the self-antigen that MHC can present, is only a fraction of all self-antigen peptide fragments that can be produced from the human body. And T-cells that learn to recognize self, with one self-antigen per T-cell receptor, would only have to recognize the self-antigen that MHC can present.

description: ObjectiveTo estimate the burden of diarrhoeal diseases from exposure to inadequate water, sanitation and hand hygiene in low- and middle-income settings and provide an overview of the impact on other diseases.MethodsFor estimating the impact of water, sanitation and hygiene on diarrhoea, we selected exposure levels with both sufficient global exposure data and a matching exposure-risk relationship. Global exposure data were estimated for the year 2012, and risk estimates were taken from the most recent systematic analyses. We estimated attributable deaths and disability-adjusted life years (DALYs) by country, age and sex for inadequate water, sanitation and hand hygiene separately, and as a cluster of risk factors. Uncertainty estimates were computed on the basis of uncertainty surrounding exposure estimates and relative risks.ResultsIn 2012, 502000 diarrhoea deaths were estimated to be caused by inadequate drinking water and 280000 deaths by inadequate sanitation. The most likely estimate of disease burden from inadequate hand hygiene amounts to 297000 deaths. In total, 842000 diarrhoea deaths are estimated to be caused by this cluster of risk factors, which amounts to 1.5% of the total disease burden and 58% of diarrhoeal diseases. In children under 5years old, 361000 deaths could be prevented, representing 5.5% of deaths in that age group.ConclusionsThis estimate confirms the importance of improving water and sanitation in low- and middle-income settings for the prevention of diarrhoeal disease burden. It also underscores the need for better data on exposure and risk reductions that can be achieved with provision of reliable piped water, community sewage with treatment and hand hygiene.

description: In 2013 April a new magnetar, SGR 1745-2900, was discovered as it entered an outburst, at only 2.4 arcsec angular distance from the supermassive black hole at the Centre of the Milky Way, Sagittarius A*. SGR 1745-2900 has a surface dipolar magnetic field of ~ 2x10^{14} G, and it is the neutron star closest to a black hole ever observed. The new source was detected both in the radio and X-ray bands, with a peak X-ray luminosity L_X ~ 5x10^{35} erg s^{-1}. Here we report on the long-term Chandra (25 observations) and XMM-Newton (8 observations) X-ray monitoring campaign of SGR 1745-2900, from the onset of the outburst in April 2013 until September 2014. This unprecedented dataset allows us to refine the timing properties of the source, as well as to study the outburst spectral evolution as a function of time and rotational phase. Our timing analysis confirms the increase in the spin period derivative by a factor of ~2 around June 2013, and reveals that a further increase occurred between 2013 Oct 30 and 2014 Feb 21. We find that the period derivative changed from 6.6x10^{-12} s s^{-1} to 3.3x10^{-11} s s^{-1} in 1.5 yr. On the other hand, this magnetar shows a slow flux decay compared to other magnetars and a rather inefficient surface cooling. In particular, starquake-induced crustal cooling models alone have difficulty in explaining the high luminosity of the source for the first ~200 days of its outburst, and additional heating of the star surface from currents flowing in a twisted magnetic bundle is probably playing an important role in the outburst evolution.
