Metabolic processing of proteins during renal passage

description: The underlying mechanism of albuminuria has generally been attributed to a loss of glomerular permselectivity, involving a loss of charge selectivity and/or the formation of large pores in the glomerular capillary wall (GCW). Contrary to this, studies have shown that the GCW is not significantly charge or conformation selective, and that the mechanisms of albuminuria are centred at the post-filtration processing events. Despite this body of evidence highlighting the importance of post- filtration processing of albumin, there are ongoing controversies in the literature regarding the mechanisms of albuminuria. This thesis aims to address these controversies and re-examines the renal processing of proteins, in particular albumin, and low molecular weight proteins (LMWP). Although studies have shown the contrary, albuminuria, or increased fractional clearance (FC) of albumin, in nephrotic states is still being attributed to glomerular permeability dysfunction. A portion of this thesis re-examines this issue and presents studies confirming that charge selectivity does not govern the FC of albumin, and that large pores in the GCW do not account for albuminuria. In the same manner, hypoalbuminemia, or increased albumin loss from the plasma, is thought to be controlled by mechanisms centred at the GCW. A large portion of this thesis focuses on the plasma elimination of albumin and re-evaluates the issue of glomerular permselectivity. The studies presented demonstrate that increased plasma clearance of albumin, with accompanying increase in urinary excretion, is not due to increased glomerular permeability, but rather, is associated with post-filtration processing events. The majority of studies on renal function and proteinuria have been performed on albumin. There are no similar studies on LMWP. The LMWP have not been examined since the very early studies performed more than 30 years ago using ex- vivo techniques. A section of this thesis examines the renal processing of LMWP in- vivo, in comparison studies with albumin. Although it has generally been assumed that all proteins are processed by the same mechanism in the kidney, this thesis demonstrates differential renal processing of albumin as compared to LMWP. This finding has great impact on the interpretation of proteinuria and its underlying mechanisms, and provides plausible explanation why low molecular weight proteinuria and albuminuria are entirely separate processes. Finally, this thesis discusses the findings that highlight the important and under- estimated role of post-filtration processing events in the mechanisms of albuminuria and hypoalbuminemia. This has great clinical implication, as it is important for clinicians to distinguish albuminuria that gives rise to clinically significant hypoalbuminemia, from albuminuria with no associated hypoalbuminemia.

description: PSR J1023+0038 is the first millisecond pulsar that was ever observed as an optical and UV pulsar. So far, it is the only optical transitional millisecond pulsar. The rotation- and accretion-powered emission mechanisms hardly individually explain the observed characteristics of optical pulsations. A synergistic model, combining these standard emission processes, was proposed to explain the origin of the X-ray/UV/optical pulsations. We study the phase lag between the pulses in the optical and X-ray bands to gain insight into the physical mechanisms that cause it. We performed a detailed timing analysis of simultaneous or quasi-simultaneous observations in the X-ray band, acquired with the XMM-Newton and NICER satellites, and in the optical band, with the fast photometers SiFAP2 (mounted at the 3.6 m Telescopio Nazionale Galileo) and Aqueye+ (mounted at the 1.8 m Copernicus Telescope). We estimated the time lag of the optical pulsation with respect to that in the X-rays by modeling the folded pulse profiles with two harmonic components. Optical pulses lag the X-ray pulses by $\sim$ 150 $μ$s in observations acquired with instruments (NICER and Aqueye+) whose absolute timing uncertainty is much smaller than the measured lag. We also show that the phase lag between optical and X-ray pulsations lies in a limited range of values, $δϕ\in$ (0 $-$ 0.15), which is maintained over timescales of about five years. This indicates that both pulsations originate from the same region, and it supports the hypothesis of a common emission mechanism. Our results are interpreted in the shock-driven mini pulsar nebula scenario. This scenario suggests that optical and X-ray pulses are produced by synchrotron emission from the shock that formed within a few light cylinder radii away ($\sim$ 100 km) from the pulsar, where its striped wind encounters the accretion disk inflow.

description: No studies to date have considered the effectiveness of fact-based directions relative to other enhanced forms of directions in terms of comprehension and application of legal principles. Furthermore, little is known about the effects of fact-based directions in realistic simulated jury settings. The research project sought to compare four forms of instructions: (1) standard; (2) plain language; (3) checklist; (4) fact-based in terms of comprehension and application of legal concepts. The research project utilised a sample of 1007 adults who had been called for jury service in the Victorian County and Supreme Courts over a twelve month period. Participants were tested in groups of 10-12 and engaged in a realistic one day simulated trial including deliberation. Testing of participants occurred at three time points- pre-trial, pre-deliberation, and where time allowed, at post-deliberation. Results indicated that comprehension of directions was significantly higher in all modified (plain language, checklist, fact-based) instructional types compared to standard instructions at the pre-deliberation stage of trial. Findings around application of law were mixed. At the pre-deliberation stage, participants receiving fact-based instructions had significantly higher scores on true/false application questions compared with participants in other conditions at the pre-deliberation stage, whereas there were no significant differences between conditions for multiple choice application. However, opportunistic testing of a limited number of participants following deliberation revealed that participants in the fact-based condition had significantly higher scores on multiple-choice application items. The results support previous findings on plain language instructions and comprehension and support the use of revisions such as checklists, question-trails and restructuring of the charge more generally. Participants provided with fact-based directions scored better on tests of comprehension than participants receiving standard instructions. Participants provided with fact-based directions also scored significantly higher on tests of true/false application than participants in all other conditions. Finally, instruction type was found to interact with deliberation, with participants receiving fact-based directions scoring far higher than participants in all other conditions at the post-deliberation

description: Magnetic field generation in three-dimensional Rayleigh-Bénard convection of an electrically conducting fluid is studied numerically by fixing the Prandtl number at $P=0.3$ and varying the Rayleigh number (Ra) as a control parameter. A recently reported route to hyperchaos involving quasiperiodic regimes, crises and chaotic intermittent attractors is followed, and the critical magnetic Prandtl number ($P_m^c$) for dynamo action is determined as a function of Ra. A mechanism for the onset of intermittency in the magnetic energy is described, the most beneficial convective regimes for dynamo action in this transition to weak turbulence are identified, and the impact of intermittency on the dependence of $P_m^c$ on Ra is discussed.

description: The pressure-strain interaction describes the rate per unit volume that energy is converted between bulk flow and thermal energy in neutral fluids or plasmas. The term has been written as a sum of the pressure dilatation and the collisionless analogue of viscous heating referred to as ${\rm Pi-D}$, which isolates the power density due to compressible and incompressible effects, respectively. It has been shown that ${\rm Pi-D}$ can be negative, which makes its identification as collisionless viscous heating troubling. We argue that an alternate decomposition of pressure-strain interaction can be useful for interpreting the underlying physics. Since ${\rm Pi-D}$ contains both normal deformation and shear deformation, we propose grouping the normal deformation with the pressure dilatation to describe the power density due to converging/diverging flows, with the balance describing the power density purely due to shear deformation. We then develop a kinetic theory interpretation of compression, normal deformation, and shear deformation. We use the results to determine the physical mechanisms that can make ${\rm Pi-D}$ negative. We argue that both decompositions can be useful for the study of energy conversion in weakly collisional or collisionless fluids and plasmas, and implications are discussed.

description: Orientational order, encoded in anisotropic fields, plays an important role during the development of an organism. A striking example of this is the freshwater polyp Hydra, where topological defects in the muscle fiber orientation have been shown to localize to key features of the body plan. This body plan is organized by morphogen concentration gradients, raising the question how muscle fiber orientation, morphogen gradients and body shape interact. Here, we introduce a minimal model that couples nematic orientational order to the gradient of a morphogen field. We show that on a planar surface alignment to a radial concentration gradient can induce unbinding of topological defects, as observed during budding and tentacle formation in Hydra, and stabilize aster/vortex-like defects, as observed at a Hydra's mouth. On curved surfaces mimicking the morphologies of Hydra in various stages of development -- from spheroid to adult -- our model reproduces the experimentally observed reorganization of orientational order. Our results suggest how gradient alignment and curvature effects may work together to control orientational order during development and lays the foundations for future modeling efforts that will include the tissue mechanics that drive shape deformations.

description: Parental imprisonment can cause many problems for the family left behind, including difficulty organising childcare, loss of family income, trouble maintaining contact with the imprisoned parent, stigma, and home, school and neighbourhood moves. Children and parents can be distressed by the separation. Children may respond by acting out or becoming withdrawn, anxious or depressed. We conducted an exhaustive search for studies that examined children's antisocial behaviour and mental health after parental imprisonment. We found 16 studies with appropriate evidence. These studies all showed that children of prisoners are more likely than other children to show antisocial and mental health problems. However, it was unclear whether parental imprisonment actually caused these problems. They might have been caused by other disadvantages in children's lives that existed before parental imprisonment occurred. Children of prisoners are a vulnerable group. More research is required to determine whether or not parental imprisonment causes an increase in child antisocial behaviour and mental health problems.

description: In weakly collisional and collisionless magnetized plasmas, the pressure-strain interaction describes the rate of conversion between bulk flow and thermal energy density. In this study, we derive an analytical expression for the pressure-strain interaction in a coordinate system with an axis aligned with the local magnetic field. The result is eight groups of terms corresponding to different physical mechanisms that can contribute to the pressure-strain interaction. We provide a physical description of each term. The results are immediately of interest to weakly collisional and collisionless magnetized plasmas and the fundamental processes that happen therein, including magnetic reconnection, magnetized plasma turbulence, and collisionless shocks. The terms in the field-aligned coordinate decomposition are likely accessible to measurement with satellite observations.

description: To understand the X-ray emission of active galactic nuclei (AGNs), we explored the optical-to-X-ray variation correlation of a radio-loud quasar (RLQ) SDSS J121426.52+140258.9 (hereafter J1214+1402) with multi-epoch observations of Swift and XMM-Newton telescopes. With the historical multi-band data, we found that the infrared to X-ray flux of RLQ J1214+1402 should not be dominated by the beamed jet emission. The Swift optical/UV and X-ray light curves showed that J1214+1402 has two optical states with low flux before 2014 April 08 and high flux after 2014 June 11, but has no significant X-ray variations during the time range between 2007 March 09 and 2014 August 04. This result was supported by the XMM-Newton observations in the overlapped time with Swift. Interestingly, the early XMM-Newton data prior to the Swift time presents two unusual emission epochs when J1214+1402 has relatively low optical fluxes but has the brightest X-ray fluxes. The overall independence of optical-to-X-ray variation seems hard to be described by the disk-corona model. With the X-ray spectral fitting, we find that the soft X-ray excess in J1214+1402 appears only during the high optical state when the X-ray emission is at low state. The soft X-ray excess in J1214+1402 is difficult to be explained by the ionized accretion disk, instead, it may be related to the warm corona.

description: The expected volume of data from the third-generation gravitational waves (GWs) Einstein Telescope (ET) detector would make traditional GWs search methods such as match filtering impractical. This is due to the large template bank required and the difficulties in waveforms modelling. In contrast, machine learning (ML) algorithms have shown a promising alternative for GWs data analysis, where ML can be used in developing semi-automatic and automatic tools for the detection, denoising and parameter estimation of GWs sources. Compared to second generation detectors, ET will have a wider accessible frequency band but also a lower noise. The ET will have a detection rate for Binary Black Holes (BBHs) and Binary Neutron Stars (BNSs) of order 1e5 - 1e6 per year and 7e4 per year respectively. In this work, we explore the possibility and efficiency of using convolutional neural networks (CNNs) for the detection of BBHs mergers in synthetic GWs signals buried in gaussian noise. The data was generated according to the ETs parameters using open-source tools. Without performing data whitening or applying bandpass filtering, we trained four CNN networks with the state-of-the-art performance in computer vision, namely VGG, ResNet and DenseNet. ResNet has significantly better performance, detecting BBHs sources with SNR of 8 or higher with 98.5% accuracy, and with 92.5%, 85%, 60% and 62% accuracy for sources with SNR range of 7-8, 6-7, 5-6 and 4-5 respectively. ResNet, in qualitative evaluation, was able to detect a BBHs merger at 60 Gpc with 4.3 SNR. It was also shown that, using CNN for BBHs merger on long time series data is computationally efficient, and can be used for near-real-time detection.

description: Blind quantum computation protocols allow a user to delegate a computation to a remote quantum computer in such a way that the privacy of their computation is preserved, even from the device implementing the computation. To date, such protocols are only known for settings involving at least two quantum devices: either a user with some quantum capabilities and a remote quantum server or two or more entangled but noncommunicating servers. In this work, we take the first step towards the construction of a blind quantum computing protocol with a completely classical client and single quantum server. Specifically, we show how a classical client can exploit the ambiguity in the flow of information in measurement-based quantum computing to construct a protocol for hiding critical aspects of a computation delegated to a remote quantum computer. This ambiguity arises due to the fact that, for a fixed graph, there exist multiple choices of the input and output vertex sets that result in deterministic measurement patterns consistent with the same fixed total ordering of vertices. This allows a classical user, computing only measurement angles, to drive a measurement-based computation performed on a remote device while hiding critical aspects of the computation.

description: We use ${\cal N}=2^*$ and cascading gauge theory holographic models to extract the general features of the gravitational susceptibility $κ$ of strongly coupled nonconformal quark-gluon plasma. We show that in theories with a relevant coupling constant the gravitational susceptibility is renormalization scheme dependent. We propose to use its temperature derivative, i.e., $\frac{dκ}{d\ln T}$, as a scheme-independent characteristic of a QGP. Although $κ$ is a thermodynamic quantity, its critical behavior can be drastically distinct in the vicinity of seemingly identical thermal phase transitions.

description: In this paper we simulate the cyclic circularly-polarised pulses of the ultra-cool dwarf TVLM513-46546, observed with the VLA at 4.88 and 8.44 GHz on May 2006, by using a 3D model of the auroral radio emission from the stellar magnetosphere. During this epoch, the radio light curves are characterised by two pulses left-hand polarised at 4.88 GHz, and one doubly-peaked (of opposite polarisations) pulse at 8.44 GHz. To take into account the possible deviation from the dipolar symmetry of the stellar magnetic field topology, the model described in this paper is also able to simulate the auroral radio emission from a magnetosphere shaped like an offset-dipole. To reproduce the timing and pattern of the observed pulses, we explored the space of parameters controlling the auroral beaming pattern and the geometry of the magnetosphere. Through the analysis of the TVLM513-46546 auroral radio emission, we derive some indications on the magnetospheric field topology that is able to simultaneously reproduce the timing and patterns of the auroral pulses measured at 4.88 and 8.44 GHz. Each set of model solutions simulates two auroral pulses (singly or doubly peaked) per period. To explain the presence of only one 8.44 GHz pulse per period, we analyse the case of auroral radio emission limited only to a magnetospheric sector activated by an external body, like the case of the interaction of Jupiter with its moons.

We find that: (a) 12 of our 18 stars show emission lines, despite not being associated with an H II region, suggestive of stellar activity (e.g., mass loss, accretion, binary star interaction), which is consistent with previous predictions of enhanced activity at low metallicity; (b) 6 are Be stars, which are the first to be spectroscopically studied at such low metallicity -- these Be stars have unusual panchromatic SEDs; (c) for stars well-fit by the TLUSTY non-local thermodynamic equilibrium (non-LTE) models, the photometric and spectroscopic values of T_eff and log(g) agree to within ~0.01 dex and ~0.18 dex, respectively, indicating that NUV/optical/NIR imaging can be used to reliably characterize massive (M ~ 8-30 M_sun) main sequence star properties relative to optical spectroscopy; (d) the properties of the most massive stars in H II regions are consistent with constraints from previous nebular emission line studies; and (e) 13 stars with M>8 M_sun are >40 pc from a known star cluster or H II region. Our sample comprises ~50% of all known massive stars at Z < 10% Z_sun with derived stellar parameters, high-quality optical spectra, and panchromatic photometry.

description: This letter proposes an analytical framework to evaluate the coverage performance of a cellular-connected unmanned aerial vehicle (UAV) network in which UAV user equipments (UAV-UEs) are equipped with directional antennas and move according to a three-dimensional (3D) mobility model. The ground base stations (GBSs) equipped with practical down-tilted antennas are distributed according to a Poisson point process (PPP). With tools from stochastic geometry, we derive the handover probability and coverage probability of a random UAV-UE under the strongest average received signal strength (RSS) association strategy. The proposed analytical framework allows to investigate the effect of UAV-UE antenna beamwidth, mobility speed, cell association, and vertical motions on both the handover probability and coverage probability. We conclude that the optimal UAV-UE antenna beamwidth decreases with the GBS density, and the omnidirectional antenna model is preferred in the sparse network scenario. What's more, the superiority of the strongest average RSS association over the nearest association diminishes with the increment of GBS density.

Genetic characterisation of Emerin and Lamin A in zebrafish models of Emery-Dreifuss muscular dystrophy

Subjects: Uncategorized

description: Emery-Dreifuss muscular dystrophy (EDMD) is a mild muscular dystrophy, which is characterised by specific muscle degeneration, joint contractures and cardiac conduction defects. Mutations in genes encoding LINC (LInker of Nucleoskeleton and Cytoskeleton) components contribute to about 40% of EDMD cases. The LINC complex is an evolutionarily conserved structure at the nuclear envelope (NE), which physically connects the nucleus to cytoplasm and regulates nucleokinesis. Exactly how defects in the NE generate the pathology evident in this disease remains unclear. There are two major hypotheses about the cause of EDMD: the first suggests that EDMD is caused by nuclear structural disruptions due to mechanical stress, while the other one proposes that some muscle specific aberrant signalling events lead to EDMD. This thesis examined the cellular basis of EDMD pathogenesis using zebrafish models. Our study established a number of zebrafish models of EDMD by inactivation of LINC components Emerin and Lamin A, and uncovered a series of EDMD-related pathologic events in mutant contexts at different developmental stages. I discovered that abnormal Notch signalling can be the primary pathogenic factor of the disease, which leads to aberrant somite segmentation and subsequent tissue specific defects in the Emerin and Lamin A deficient zebrafish. Taking advantage of the zebrafish model, I investigated the in vivo dynamics of Emerin and Lamin A at the NE. We showed that the molecular activities of Emerin and Lamin A are altered at the NE in the context of EDMD, which is in line with findings of mammalian cells in vitro. In addition, I discovered an unexpected novel “Emerin bridge” phenomenon, that EGFP-Emerin filaments from one nucleus dynamically interact with the adjacent nucleus within individual muscle fibres, implying the presence of intermolecular dynamics undefined at the NE. The results of this study can provide insights in the molecular basis of EDMD pathogenesis and be of direct therapeutic relevance.

description: We have performed ground-based transmission spectroscopy of the hot Jupiter HAT-P-18b using the ACAM instrument on the William Herschel Telescope (WHT). Differential spectroscopy over an entire night was carried out at a resolution of $R \approx 400$ using a nearby comparison star. We detect a bluewards slope extending across our optical transmission spectrum which runs from 4750 to 9250Å. The slope is consistent with Rayleigh scattering at the equilibrium temperature of the planet (852K). We do not detect enhanced sodium absorption, which indicates that a high-altitude haze is masking the feature and giving rise to the Rayleigh slope. This is only the second discovery of a Rayleigh scattering slope in a hot Jupiter atmosphere from the ground, and our study illustrates how ground-based observations can provide transmission spectra with precision comparable to the Hubble Space Telescope.

A Scheme to fabricate magnetic graphene-like cobalt nitride CoN4monolayer proposed by first-principles calculations

description: We propose a scheme to fabricate the cobalt nitride CoN4 monolayer, a magnetic graphene-like two-dimensional material, in which all Co and N atoms are in a plane. Under the pressure above 40 GPa, the bulk CoN4 is stabilized in a triclinic phase. With the pressure decreasing, the triclinic phase of CoN4 is transformed into an orthorhombic phase, and the latter is a layered compound with large interlayer spacing. At ambient condition, the weak interlayer couplings are so small that single CoN4 layer can be exfoliated by the mechanical method.

description: We introduce a notion of ellipticity of complexes of linear pseudodifferential operators acting on sections of $A$-Hilbert bundles over smooth manifolds, $A$ being a $C^*$-algebra. We prove that the cohomology groups of an $A$-elliptic pseudodifferential complex in finitely generated projective $A$-Hilbert bundles over a compact manifold are norm complete finitely generated $A$-modules if the images of the associated Laplacians are closed. This establishes a Hodge theory for these structures.

description: With the convergence of banking services and mobile technologies, users are able to conduct banking services at any place and at any time through mobile banking. This is, therefore; mobile banking has a vital advantage for customers. The main purpose of this study is to assess the practice of mobile banking and its challenges in Commercial Bank of Ethiopia. In so doing, the research used the extended TAM Model, which deals with the factors influencing the practice of mobile banking i.e., Convenience (perceived usefulness and perceived ease of use), perceived trust, perceived risk, perceived cost. Moreover, the research used infrastructure as independent variable to examine its effect of the practice of mobile banking. Data for the study was collected through closed ended questionnaire which were distributed for 330 respondents and analysis of findings are done based on 313 complete responses. The study employed mean, frequency and t-test extracted from SPSS for analysis. Accordingly, the research has found that customers in the CBE perceived that mobile banking service is useful and easy to use. Customers who are using mobile banking service (86.9%) perceives that cost and risk doesn't affect the practice of mobile banking, whereas, 13.1% of the customers who are not using mobile banking perceives that risk and cost are barriers to use the mobile banking service. In addition, customers at CBE perceive that infrastructure is the most critical factor for the customer to use mobile banking service. Furthermore, the t-test result shows all variables considered have a significant effect on the practice of mobile banking as their probability values are less than 5%.
