description: Accreting, nuclear-burning white dwarfs have been deemed to be candidate progenitors of type Ia supernovae, and to account for supersoft X-ray sources, novae, etc. depending on their accretion rates. We have carried out a binary population synthesis study of their populations using two algorithms. In the first, we use the binary population synthesis code \textsf{BSE} as a baseline for the "rapid" approach commonly used in such studies. In the second, we employ a "hybrid" approach, in which we use \textsf{BSE} to generate a population of white dwarfs (WD) with non-degenerate companions on the verge of filling their Roche lobes. We then follow their mass transfer phase using the detailed stellar evolution code \textsf{MESA}. We investigate the evolution of the number of rapidly accreting white dwarfs (RAWDs) and stably nuclear-burning white dwarfs (SNBWDs), and estimate the type Ia supernovae (SNe Ia) rate produced by "single-degenerate" systems (SD). We find significant differences between the two algorithms in the predicted numbers of SNBWDs at early times, and also in the delay time distribution (DTD) of SD SNe Ia. Such differences in the treatment of mass transfer may partially account for differences in the SNe Ia rate and DTD found by different groups. Adopting 100\% efficiency for helium burning, the rate of SNe Ia produced by the SD-channel in a Milky-way-like galaxy in our calculations is $2.0\times10^{-4}\rm{yr}^{-1}$, more than an order of magnitude below the observationally inferred value. In agreement with previous studies, our calculated SD DTD is inconsistent with observations.

description: We report the discovery of a young stellar bridge, that forms a continuous connection between the Magellanic Clouds. This finding is based on number density maps for stellar populations found in data gathered by OGLE-IV, that fully cover over 270 deg^2 of the sky in the Magellanic Bridge area. This is the most extensive optical survey of this region up to date. We find that the young population is present mainly in the western half of the MBR, which, together with the newly discovered young population in the eastern Bridge, form a continuous stream of stars connecting both galaxies along Dec ~ -73.5 deg. The young population distribution is clumped, with one of the major densities close to the SMC, and the other, fairly isolated and located approximately mid-way between the Clouds, which we call the OGLE island. These overdensities are well matched by HI surface density contours, although the newly found young population in the eastern Bridge is offset by ~2 deg north from the highest HI density contour. We observe a continuity of red clump stars between the Magellanic Clouds, which represent an intermediate-age population. Red clump stars are present mainly in the southern and central parts of the Magellanic Bridge, below its gaseous part, and their presence is reflected by a strong deviation from the radial density profiles of the two galaxies. This may indicate either a tidal stream of stars, or that the stellar halos of the two galaxies overlap. On the other hand, we do not observe such an overlap within an intermediate-age population represented by the top of the red giant branch and the asymptotic giant branch stars. We also see only minor mixing of the old populations of the Clouds in the southern part of the Bridge, represented by the lowest part of the red giant branch.

description: It is proposed that the recently announced BICEP2 value of tensor-to scalar ratio $r\sim0.2$ can be explained as containing an extra contribution from the recent acceleration of the universe. In fact this contribution, being robust, recent and of much longer duration (by a large order of magnitude) may dominate the contribution from the inflationary origin. In a possible scenario, matter (dark or baryonic) and radiation etc. can emerge from a single Higgs-like tachyonic scalar field in the universe through a physical mechanism not yet fully known to us. The components interact among themselves to achieve the thermodynamical equilibrium in the evolution of the universe. The field potential for the present acceleration of the universe would give a boost to the amplitude of the tensor fluctuations of gravity waves generated by the early inflation and the net effects may be higher than the earlier PLANCK bounds. In the process, the dark energy, as a cosmological constant decays into creation of dark matter. The diagnostics for the three-component, spatially homogeneous tachyonic scalar field are discussed in detail. The components of the field with perturbed equation of state are taken to interact mutually and the conservation of energy for individual components gets violated. We study mainly the $O_{m}(x)$ diagnostics with the observed set of $H(z)$ values at various redshifts, and the dimensionless state-finders for these interacting components. This analysis provides a strong case for the interacting dark energy in our model.

description: We analyze an AC-driven dimer chain connected to a strongly biased electron source and drain. It turns out that the resulting transport exhibits fingerprints of topology. They are particularly visible in the driving-induced current suppression and the Fano factor. Thus, shot noise measurements provide a topological phase diagram as a function of the driving parameters. The observed phenomena can be explained physically by a mapping to an effective time-independent Hamiltonian and the emergence of edge states. Moreover, by considering quantum dissipation, we determine the requirements for the coherence properties in a possible experimental realization. For the computation of the zero-frequency noise, we develop an efficient method based on matrix-continued fractions.
title: Studies in Mice and Patients to Understand the Role of Tau Pathology in Driving Neurodegeneration After Traumatic Brain Injury
Creators: name: Vegliante, Gloria
Publisher: name: The Open University
Year: 2025

description: Traumatic brain injury (TBI) is a global public health issue that afflicts 55 million people worldwide. It represents a huge burden for the health system, and a leading cause of injury-related death and disability, with devastating impact on individuals and society. TBI is a complex disease characterised by dynamic pathophysiological adaptive and maladaptive processes that may predispose to chronic neurodegeneration and increase risk of dementia later in life including Alzheimer’s disease (AD). However, the mechanisms driving the transition from the acute biomechanical impact to late neurodegeneration still need to be fully addressed.

 The development of progressive proteinopathies is a shared feature of dementia and TBI. In particular, tau pathology has sparked our interest being a hallmark of AD and pathognomonic feature of chronic traumatic encephalopathy. In the present study we document the presence of tau pathology in human brain contusion samples surgically removed early after severe TBI in patients. We provide evidence that human TBI-induced tau (tauTBI) has self-templating properties and spreads throughout the brain causing a widespread tau pathology that is associated with synaptic dysfunction and cognitive impairment. Moreover, we show that tauTBI can be horizontally transmitted to naïve mice by intracerebral inoculation, causing memory deficits. Thus, human tauTBI holds prion-like properties, suggesting a mechanism by which an acute biomechanical impact may predispose to neurodegeneration in patients. We also show an impairment of proteostatic mechanisms in chronic TBI mice, thus further contributing to tau accumulation later in life. Interestingly, tau deficiency reduces the physiological cognitive aged-related decline in mice. Finally, we exploit the C. elegans model to demonstrate that the bio-inspired multitarget hexapeptide Aβ1-6A2V(D), acting against amyloid β and tau, could represent an innovative pharmacological approach to counteract pathological aggregates formation and mitigate the progression of dementia and post-traumatic neurodegenerative processes.

title: Exploring the role of deadwood in the forest soil carbon cycle
Creators: name: Shannon, Victoria
Publisher: name: University of Reading
Year: 2022

description: Deadwood is an important part of forest ecosystems, holding ~5% of global forest carbon, and providing other ecosystem services such as habitat for biodiversity, natural flood management, and production of woodfuel. Threshold volumes of deadwood, usually >20 m3 ha-1 , are aimed for, to help preserve biodiversity. The carbon stocks held in deadwood are now included as a pool to report in carbon inventories such as the Global Forest Resource Assessment. However, the exact contribution of deadwood from woodlands in Great Britain is unknown, with estimates of carbon stocks being based on simplistic calculations, assuming all deadwood is uniform and that volumes do not change over time. Additionally, there is little research into how volumes and carbon stocks vary between factors such as woodland type, origin, and management. In this work, we aimed to quantify the effects of these factors and ascertain how this compares to other forest floor materials. We also aimed to identify whether significant fluxes of dissolved organic carbon (DOC) were released from deadwood during decomposition, and whether this ‘primed’ soil microbes. This was carried out from plot scale experiments to national scale using data from the National Forest Inventory. We conclude that across GB, an average deadwood volume of 26 m3 ha-1 occurred. However, this significantly differed between countries in GB, woodland type, and management practices. Carbon stocks were calculated with wood density and carbon concentrations specific to tree species and decay class, which proved to significantly differ when compared to the standard calculation used for national reporting. Changes to wood density significantly affected the overall carbon stocks reported, while carbon concentration did not. It is possible deadwood provides a significant source of DOC into underlying soil, producing as much DOC per g material as leaf litter, though overall fluxes depend on the volume of deadwood present. The fate of DOC released by deadwood is currently unknown as there is no evidence that it causes a priming effect on soil microbes, and further study is required to ascertain whether deadwood derived DOC is strongly minerally-associated, or recalcitrant.

description: In this article, changes occur in the child's body and psychology during the transition from kindergarten to school education. It begins the period of adaptation. In this process, the child faces a number of difficulties. The process of passing the game makes it difficult for the child to perceive the learning process himself. In these cases, the cooperation between parents and the preschool educational institution is very important, and the creation of a common educational environment between the preschool educational organization and the school is one of the factors affecting the adaptation of the elementary school student in the society. About the continuity of kindergarten and school work, the problem of adapting the first grader to new educational conditions and the role of child psychologists, teachers, doctors and scientists in this field occupy a special place in solving this problem the word goes.

description: Schizophrenia is a severe, debilitating, chronic disease that is accompanied by morphologic changes within the brain. However, it is unclear to what extent alterations of grey and white matter in schizophrenia are linked to the disease itself, or whether they are a consequence of neuroleptic treatment. Typical and atypical antipsychotics exert differential effects on brain structure. Moreover, atypical antipsychotics may have distinct profiles with respect to grey matter in schizophrenic patients. Findings on drug-induced grey matter changes are heterogeneous due to variation in stage of illness, duration of treatment and use of multiple antipsychotics. Using voxel-based morphometry applied to high-resolution magnetic resonance images, we show that monotherapy with the atypical agent quetiapine (mean daily dose = 445 mg ± 200 s.d.) may induce structural brain changes in first-episode schizophrenia patients (N = 20) within 21 d of treatment. Specifically, we demonstrate longitudinal macroscopic changes (i.e. grey matter increases) in the left amygdalohippocampal region that were predicted by drug plasma levels but not daily doses. These structural alterations were accompanied by a clinical improvement of schizophrenic symptoms. Comparison with healthy controls (n = 30) showed that grey matter amount in the respective amygdalar region was significantly reduced in unmedicated first-episode schizophrenia patients. These findings suggest that drug-induced neuroplastic changes in schizophrenia can occur quickly and are dependent on pharmacokinetics.

description: Forward inference techniques such as sequential Monte Carlo and particle Markov chain Monte Carlo for probabilistic programming can be implemented in any programming language by creative use of standardized operating system functionality including processes, forking, mutexes, and shared memory. Exploiting this we have defined, developed, and tested a probabilistic programming language intermediate representation language we call probabilistic C, which itself can be compiled to machine code by standard compilers and linked to operating system libraries yielding an efficient, scalable, portable probabilistic programming compilation target. This opens up a new hardware and systems research path for optimizing probabilistic programming systems.

description: Two-dimensional carbon nanomaterials ranging from single-layer graphene to defective structures such as chemically reduced graphene oxide were studied with respect to their use in electrodes and sensors. Their electrochemical properties and utility in terms of fabrication of sensing devices are compared. Specifically, the electrodes have been applied to reductive amperometric determination of hydrogen peroxide. Low-defect graphene (SG) was obtained through mechanical exfoliation of natural graphite, while higher-defect graphenes were produced by chemical vapor deposition (CVDG) and by chemical oxidation of graphite and subsequent reduction (rGO). The carbonaceous materials were mainly characterized by Raman microscopy. They were applied as electrode material and the electrochemical behavior was investigated by chronocoulometry, cyclic voltammetry, electrochemical impedance spectroscopy and amperometry and compared to a carbon disc electrode. It is shown that the quality of the graphene has an enormous impact on the amperometric performance. The use of carbon materials with many defects (like rGO) does not result in a significant improvement in signal compared to a plain carbon disc electrode. The sensitivity is 173 mA center dot M-1 center dot cm(-2) in case of using CVDG which is about 50 times better than that of a plain carbon disc electrode and about 7 times better than that of rGO. The limit of detection for hydrogen peroxide is 15.1 mu M (at a working potential of -0.3 V vs SCE) for CVDG. It is concluded that the application of two-dimensional carbon nanomaterials offers large perspectives in amperometric detection systems due to electrocatalytic effects that result in highly sensitive detection.

Minimal ancilla mediated quantum computation

description: Schemes of universal quantum computation in which the interactions between the computational elements, in a computational register, are mediated by some ancillary system are of interest due to their relevance to the physical implementation of a quantum computer. Furthermore, reducing the level of control required over both the ancillary and register systems has the potential to simplify any experimental implementation. In this paper we consider how to minimise the control needed to implement universal quantum computation in an ancilla-mediated fashion. Considering computational schemes which require no measurements and hence evolve by unitary dynamics for the global system, we show that when employing an ancilla qubit there are certain fixed-time ancilla-register interactions which, along with ancilla initialisation in the computational basis, are universal for quantum computation with no additional control of either the ancilla or the register. We develop two distinct models based on locally inequivalent interactions and we then discuss the relationship between these unitary models and the measurement-based ancilla-mediated models known as ancilla-driven quantum computation.

description: Using the Green's function representation technique, the late time behavior of localized scalar field distributions on Schwarzschild spacetimes is studied. Assuming arbitrary initial data we perform a spectral analysis, computing the amplitude of each excited quasi-bound mode without the necessity of performing dynamical evolutions. The resulting superposition of modes is compared with a traditional numerical evolution with excellent agreement; therefore, we have an efficient way to determine final black hole wigs. The astrophysical relevance of the quasi-bound modes is discussed in the context of scalar field dark matter models and the axiverse.

description: It is known that individual metal atoms on insulating ionic films can occur in several different (meta) stable charge states, which can be reversibly switched in a controlled fashion. Here we show that the diffusion of gold adatoms on NaCl thin films depends critically on their charge state. Surprisingly, the anionic species has a lower diffusion barrier than the neutral one. Furthermore, for the former we observe that the diffusion atop a bilayer of NaCl is strongly influenced by the interface between NaCl and the underlying copper substrate. This effect disappears for a trilayer of NaCl. These observations open the prospect of controlling the diffusion properties of individual metal atoms on thin insulating films.
Measurements of the t t-bar charge asymmetry using the dilepton decay channel in pp collisions at sqrt(s) = 7 TeV

description: The t t-bar charge asymmetry in proton-proton collisions at sqrt(s) = 7 TeV is measured using the dilepton decay channel (ee, e mu, or mu mu). The data correspond to a total integrated luminosity of 5.0 inverse femtobarns, collected by the CMS experiment at the LHC. The t t-bar and lepton charge asymmetries, defined as the differences in absolute values of the rapidities between the reconstructed top quarks and antiquarks and of the pseudorapidities between the positive and negative leptons, respectively, are measured to be Ac = -0.010 +/- 0.017 (stat.) +/- 0.008 (syst.) and Ac[lep] = 0.009 +/- 0.010 (stat.) +/- 0.006 (syst). The lepton charge asymmetry is also measured as a function of the invariant mass, rapidity, and transverse momentum of the t t-bar system. All measurements are consistent with the expectations of the standard model.
