description: ßIV-spectrin is a protein of the spectrin family which is involved in the organization of the cytoskeleton structure and is found in high quantity in the axon initial segment and the nodes of Ranvier. Together with ankyrin G, ßIV-spectrin is responsible for the clustering of KCNQ2/3-potassium channels and NaV-sodium channels. Loss or reduction of ßIV-spectrin causes a destabilization of the cytoskeleton and an impairment in the generation of the action potential, which leads to neuronal degeneration. Furthermore, ßIV-spectrin has been described to play an important role in the maintenance of the neuronal polarity and of the diffusion barrier. ßIV-spectrin is also located in the heart where it takes an important part in the structural organization of ion channels and has also been described to participate in cell signaling pathways through binding of transcription factors. We describe two patients with a severe form of ßIV-spectrin deficiency. Whole-exome sequencing revealed the homozygous stop mutation c.6016C>T (p.R2006*) in the SPTBN4 gene. The phenotype of these patients is characterized by profound psychomotor developmental arrest, respiratory insufficiency and deafness. Additionally one of the patients presents with cardiomyopathy, optical nerve atrophy, and mitochondrial dysfunction. This is the first report of a severe form of ßIV-spectrin deficiency with hypertrophic cardiomyopathy and mitochondrial dysfunction.

Multi-scale models for fibre/matrix size effects in thin ply composite laminates
Creators: name: Nourmohammadi, Nastaran
Publisher: name: University of Limerick
Year: 2022
Subjects: Engineering

description: Heterogeneous materials can show size-dependent behaviour under bending in which stiffness can increase or decrease by decreasing size. In other words, while the elastic modulus calculated by the rule of mixtures can predict the tensile behaviour of these materials well, it can overestimate or underestimate their bending behaviour. Composite materials are inherently heterogeneous due to a mismatch of fibre/matrix geometry and material properties. While idealised models assume uniform fibre spacing, realised fibre spacing may be irregular due to perturbations in material quality and processing characteristics. Such variations add more parameters necessary for modelling heterogeneity in composites. Due to emerging spread-tow thin-ply technology that enables manufacturing of plies as thin as 20µm, greater variability in fibre distributions can be expected. Success in manufacturing various thicknesses of composite plies provides the need to quantify a potential size effect under bending. Indeed, the common assumption of a fibre/matrix cube (unit cell) as a representative volume element (RVE) repeated through-thickness a ply loses its validity for thin-ply composites. As a result, the cross-section of a thin composite ply should be considered as an RVE and analysed for modelling its bending behaviour. To address this problem, Euler-Bernoulli beam theory was used to calculate the bending stiffness of the cross-section with different fibre/matrix models for both uniform and non-uniform fibre spacing. An effective bending modulus is defined as the ratio of bending stiffness of heterogeneous media to the second moment of area of an equivalent homogenised cross-section. In order to quantify the size effect, a modulus variation parameter, R, is defined as the relative difference between the bending and tensile modulus. Results show that there is a maximum value of R ' 10% for a ply with three fibres and it is increasing significantly for the non-uniform fibre spacing case (R = 80%). To verify the accuracy of analytical results, finite-element analysis was used for comparison purposes. As analysing heterogeneous composite plies is computationally expensive, homogenisation through micropolar theory was done by determining a bending characteristic length responsible for the size effect. Furthermore, the significant influence of the detected size effect at the ply level on the overall bending behaviour of laminate was validated.

description: In the present study, the essential oil (EO) of Annona exsucca DC. or Rollinia exsucca was extracted by hydrodistillation, and the identification and quantification of volatile compounds were performed by GC-MS and GC-FID. A. exsucca leaves were collected from the Magalhães Barata, northeast of the State of Pará (Brazil) in March and September of 2019. Moreover, we used computational approaches to evaluate possible biological targets for the major compounds of the EO. In the sample obtained in March, 50 compounds were identified, with hydrocarbon sesquiterpenes being the predominant ones with the content of 80.52%. In the sample collected in September, 58 compounds were identified, and the chemical class of hydrocarbon monoterpenes and sesquiterpenes were the dominant ones with contents of 43.36 and 31.29%, respectively. Computational methods demonstrated that some major compounds have potential biological activity against some strains of pathogenic bacteria, as well as against molecular targets involved in cancer development.

description: We study the allocation of indivisible goods that form an undirected graph and quantify the loss of fairness when we impose a constraint that each agent must receive a connected subgraph. Our focus is on well-studied fairness notions including envy-freeness and maximin share fairness. We introduce the price of connectivity to capture the largest gap between the graph-specific and the unconstrained maximin share, and derive bounds on this quantity which are tight for large classes of graphs in the case of two agents and for paths and stars in the general case. For instance, with two agents we show that for biconnected graphs it is possible to obtain at least $3/4$ of the maximin share with connected allocations, while for the remaining graphs the guarantee is at most $1/2$. In addition, we determine the optimal relaxation of envy-freeness that can be obtained with each graph for two agents, and characterize the set of trees and complete bipartite graphs that always admit an allocation satisfying envy-freeness up to one good (EF1) for three agents. Our work demonstrates several applications of graph-theoretic tools and concepts to fair division problems.

description: Conditioned pain modulation (CPM) allows to investigate endogenous pain modulation and its clinical outcomes. Although co-activation of emotions has been shown to affect CPM, the impact of ‘threat,’ which may accompany CPM stimulation itself, has been mostly neglected. A critical factor for the threat level of the conditioning stimulus (CS) may be its predictability. 38 healthy participants (18 female) took part in a CPM study with pressure stimulation on the leg (blood-pressure cuff) serving as CS and heat stimulation on the forearm (contact thermode; CHEPS) serving as test stimulus (TS). While CS varied in intensity and –as operationalisation of threat– in temporary predictability, TS was kept constant. CPM effects were studied by EEG parameters (N2P2) and pain ratings. We found a significant CPM effect when considering N2P2, with low CS predictability augmenting CPM inhibition; in contrast, a surprisingly facilitatory CPM effect occurred in pain ratings (in the high CS predictability condition). The threat manipulation was only partially successful because CS intensity increased the threat ratings but not -as intended- CS predictability. Correlations between subjective and psychophysiological CPM responses were low. The differing CPM effects in subjective and psychophysiological responses, with both inhibitory and facilitatory effects, is puzzling but has already been observed earlier. The consideration of the CPM stimulation as major threat that is emotionally active is theoretically clearly justifiable but the operationalisation by means of different levels of CS predictability as in the present study might not have been ideal. Thus, further attempts of experimental verification are warranted.

description: One undescribed lignan, one new natural product, along with fourteen known compounds, were isolated from the roots of Ficus hirta. The structures of the isolates were elucidated by comprehensive spectroscopic technologies, including UV, IR, HRESIMS, and NMR. The absolute configuration of 1 was determined by comparison of experimental and calculated ECD data. The cytotoxicity of all the compounds against HeLa and HepG2 cell lines was evaluated and compound 7 showed considerable cytotoxic effect towards HepG2 cells. Also, the apoptotic effect of 7 on HepG2 cells and the effect of 7 on the key proteins (p-JNK and p-p38) in MAPK (Mitogen-activated protein kinases) pathways were studied by flow cytometry and western blotting experiment. As a result, compound 7 induced the apoptosis of HepG2 cells, and dose-dependently increased the phosphorylation of JNK and p38. Thus, 7 might trigger HepG2 cells apoptosis via JNK/p38 MAPK signaling pathway.

description: We experimentally study the factors that influence the span in frequency combs derived from the crystalline whispering gallery mode resonators. We observe that cavity dispersion plays an important role in generation of combs by cascaded four wave mixing process. We observed combs from the resonators with anomalous dispersion and nearly zero dispersion at the pump wavelength. In addition, the comb generation efficiency is found to be affected by the crossing of modes of different families. The influence of Raman gain is discussed as well as the role of cavity diameter and pump power. Copyright 2014 California Institute of Technology. Government sponsorship acknowledged.

description: These are lecture notes for a short winter course at the Department of Mathematics, University of Coimbra, Portugal, December 6--8, 2018. The course was part of the 13th International Young Researchers Workshop on Geometry, Mechanics and Control. In three lectures I trace the work of three heroes of mathematics and mechanics: Euler, Poincaré, and Arnold. This leads up to the aim of the lectures: to explain Arnold's discovery from 1966 that solutions to Euler's equations for the motion of an incompressible fluid correspond to geodesics on the infinite-dimensional Riemannian manifold of volume preserving diffeomorphisms. In many ways, this discovery is the foundation for the field of geometric hydrodynamics, which today encompasses much more than just Euler's equations, with deep connections to many other fields such as optimal transport, shape analysis, and information theory.

description: We discuss the onset of the thermalization process in high-energy heavy-ion collisions from a weak coupling perspective, using classical-statistical real-time lattice simulations as a first principles tool to study the pre-equilibrium dynamics. Most remarkably, we find that the thermalization process is governed by a universal attractor, where the space-time evolution of the plasma becomes independent of the initial conditions and exhibits the self-similar dynamics characteristic of wave turbulence. We discuss the consequences of our weak coupling results for the thermalization process in heavy-ion experiments and briefly comment on the use of weak coupling techniques at larger values of the coupling.

description: We present the results of large hybrid (kinetic ions - fluid electrons) simulations of particle acceleration at non-relativistic collisionless shocks. Ion acceleration efficiency and magnetic field amplification are investigated in detail as a function of shock inclination and strength, and compared with predictions of diffusive shock acceleration theory, for shocks with Mach number up to 100. Moreover, we discuss the relative importance of resonant and Bell's instability in the shock precursor, and show that diffusion in the self-generated turbulence can be effectively parametrized as Bohm diffusion in the amplified magnetic field.

Strong and nonmonotonic temperature dependence of Hall coefficient in superconducting K$_x$Fe$_{2-y}$Se$_2$ single crystals

description: In-plane resistivity, magnetoresistance and Hall effect measurements have been conducted on quenched K$_x$Fe$_{2-y}$Se$_2$ single crystals in order to analysis the normal-state transport properties. It is found that the Kohler's rule is well obeyed below about 80 K, but clearly violated above 80 K. Measurements of the Hall coefficient reveal a strong but non-monotonic temperature dependence with a maximum at about 80 K, in contrast to any other FeAs-based superconductors. With the two-band model analysis on the Hall coefficient, we conclude that a gap may open below 65 K. The data above 65 K are interpreted as a temperature induced crossover from a metallic state at a low temperature to an orbital-selective Mott phase at a high temperature. This is consistent with the recent data of angle resolved photoemission spectroscopy. These results call for a refined theoretical understanding, especially when the hole pockets are absent or become trivial in K$_x$Fe$_{2-y}$Se$_2$ superconductors.

description: Risk is an unavoidable truth and government offices, intentional and business associations are liable to some type of risk. Indeed, even with rigid administrative controls are emergency clinic and local area pharmacies not resistant from dangers of risk. Associations that neglect to oversee risks viably can confront disastrous results. Studies of bioethics challenge predominant conceptualizations of morals as global regularising standards. They observationally point out that ethics are profoundly logical, operating distinctively across local settings as actors make daily decisions. Associations have strong impacts on ethical decision-making as standards, qualities, and routines shape how medical care professionals oversee ethical issues. Practice is oftentimes coordinated around projects, and projects could be regarded as a work approach to fundamentally identify or tackle issues. A project could be the presentation of a new pharmacy service such as smoking ending, or experimenting with a novel method of communication for a particular patient group in the pharmacy for instance migraine patients. A project has the accompanying attributes; concerns numerous people, necessitates vigilant preparation, occurs throughout a characterised timeframe, has a distinct end point, and is regularly a pilot study for a larger study.

Evolving provably explainable fuzzy pattern tree classifiers using grammatical evolution
Creators: name: Murphy, Aidan
Publisher: name: University of Limerick
Year: 2022
Subjects: Engineering

description: The central hypothesis of this thesis is that Fuzzy Pattern Trees (FPTs) can be considered a powerful explainable artificial intelligence (XAI) technique and that highly accurate FPTs can be evolved using Grammatical Evolution (GE), an evolutionary computation technique. While no single definition of what constitutes an XAI system is agreed upon, we investigate the suitability of a system to be deemed as XAI based on four core criteria: transparency, accuracy, trustworthiness and the ability to incorporate domain knowledge. We start with a bottom-up system to identify useful subtrees, i.e., building blocks, in a GE run, which were subsequently made available for later generations. While this improved the performance, the complicated and unintuitive nature of the full solutions found using GE were not useful for XAI. We then pivot strategy and aim to create an intrinsically interpretable model. Specifically, we evolved FPTs using GE, which we call FGE. We systematically explore their ability to satisfy the core criteria, described above. We first show FGE meets the accuracy requirement and investigate the effect ensemble methods have on performance, improving it in half of benchmarks. Parsimony pressure was shown to reduce the size of the trees with no compromise in performance. Next, the transparency and trustworthiness of FPTs are directly investigated by a domain expert. This is done using a selection of real work benchmark problem sets. Models with sensible logic, as judged by the expert, outperform models with poor logic, validating that FGE creates interpretable models.

description: This paper introduces DGNet, a novel deep framework that exploits object gradient supervision for camouflaged object detection (COD). It decouples the task into two connected branches, i.e., a context and a texture encoder. The essential connection is the gradient-induced transition, representing a soft grouping between context and texture features. Benefiting from the simple but efficient framework, DGNet outperforms existing state-of-the-art COD models by a large margin. Notably, our efficient version, DGNet-S, runs in real-time (80 fps) and achieves comparable results to the cutting-edge model JCSOD-CVPR$_{21}$ with only 6.82% parameters. Application results also show that the proposed DGNet performs well in polyp segmentation, defect detection, and transparent object segmentation tasks. Codes will be made available at https://github.com/GewelsJI/DGNet.

description: A lot of branching ratios of the exclusive $c \to d/s\ellν_\ell$ ($\ell=e,μ$) decays have been quite accurately measured by CLEO-c, BELLE, BABAR, BES(I,II,III), ALEPH and MARKIII collaborations. We probe the R-parity violating supersymmetric effects in the exclusive $c \to d/s\ellν_\ell$ decays. From the latest experimental measurements, we obtain new upper limits on the relevant R-parity violating coupling parameters within the decays, and many upper limits are obtained for the first time. Using the constrained new parameter spaces, we predict the R-parity violating effects on the observables, which have not been measured or have not been well measured yet. We find that the R-parity violating effects due to slepton exchange could be large on the branching ratios of $D_{d/s}\to eν_e$ decays and the normalized forward-backward asymmetries of $D_{u/d}\to π/K \ellν_\ell$ as well as $D_s\to K \ellν_\ell$ decays, and all branching ratios of the relevant semileptonic $D$ decays are sensitive to squark exchange couplings. Our results in this work could be used to probe new physics effects in the leptonic decays as well as the semileptonic decays, and will correlate with searches for direct supersymmetric signals at LHC and BESIII.

The effect of macromodel uncertainties on microlensing modelling of lensed quasars

description: Cosmological gravitational microlensing has been proven to be a powerful tool to constrain the structure of multiply imaged quasars, especially the accretion disc and central supermassive black-hole system. However, the derived constraints on models may be affected by large systematic errors introduced in the various stages of modelling, namely, the macromodels, the microlensing magnification maps, and the convolution with realistic disc profiles. In particular, it has been known that different macromodels of the galaxy lens that fit the observations equally well, can lead to different values of convergence, $κ$, and shear, $γ$, required to generate magnification maps. So far, 25 microlensed quasars have been studied using microlensing techniques, where each system has been modelled and analyzed individually, or in small samples. This is about to change due to the upcoming synoptic all-sky surveys, which are expected to discover thousands of quasars suitable for microlensing studies. In the present study we investigate the connection between macromodels of the galaxy lens and microlensing magnification maps throughout the parameter space in preparation for future studies of large statistical samples of systems displaying microlensing. In particular, we use 55,900 maps produced by the GERLUMPH parameter survey (available online at http://gerlumph.swin.edu.au ) and identify regions of parameter space where macromodel uncertainties ($Δκ$,$Δγ$) lead to statistically different magnification maps. Strategies for mitigating the effect of $Δκ$,$Δγ$ uncertainties are discussed in order to understand and control this potential source of systematic errors in accretion disc constraints derived from microlensing.

description: A fundamental result in cake cutting states that for any number of players with arbitrary preferences over a cake, there exists a division of the cake such that every player receives a single contiguous piece and no player is left envious. We generalize this result by showing that it is possible to partition the players into groups of any desired sizes and divide the cake among the groups, so that each group receives a single contiguous piece and no player finds the piece of another group better than that of the player's own group.
A new perspective on the interstellar cloud surrounding the Sun from UV absorption line results

description: We offer a new, more inclusive, picture of the local interstellar medium, where it is composed of a single, monolithic cloud that surrounds the Sun in all directions. Our study of velocities based on Mg II and Fe II ultraviolet absorption lines indicates that the cloud has an average motion consistent with the velocity vector of gas impacting the heliosphere and does not behave like a rigid body: gas within the cloud is being differentially decelerated in the direction of motion, and the cloud is expanding in directions perpendicular to this flow, much like the squashing of a balloon. The outer boundary of the cloud is in average 10 pc away from us but is highly irregular, being only a few parsecs away in some directions, with possibly a few extensions up to 20 pc. Average H I volume densities vary between 0.03 and 0.1 cm-3 over different sight lines. Metals appear to be significantly depleted onto grains, and there is a steady increase in this effect from the rear of the cloud to the apex of motion. There is no evidence that changes in the ionizing radiation influence the apparent abundances. Additional, secondary velocity components are detected in 60 % of the sight lines. Almost all of them appear to be interior to the volume holding the gas that we identify with the main cloud. Half of the sight lines exhibit a secondary component moving at about - 7.2 km/s with respect to the main component, which may be the signature of an implosive shock propagating toward the cloud's interior.

On the Definition of Black Holes: Bridging the Gap Between Black Holes and Singularities

description: A novel perspective on defining black holes designed to be more broadly applicable outside of asymptotically flat spacetimes, in the context of classical general relativity, is presented, discussed, and characterized. The construction formalizes the heuristic idea that black holes are the "past Cauchy development of the set of singularities". As such, the formulation depends in a critical way on the identification of singularities, which has been treated in the literature through various boundary constructions. While many of the known boundary constructions (e.g. Schmidt's b-boundary or Geroch's g-boundary) could in principal be cited as underlying one's notion of a black hole, well-known topological concerns leads us to take the perspective that Scott and Szekeres' abstract boundary provides the most natural choice. The framework is utilized to put forward a general, non-IVP formulation of the Weak Cosmic Censorship Conjecture.

description: We study a neural network framework for the numerical evaluation of a set of Feynman integrals that appear in the perturbative description of a binary system in GeneralRelativity. We show that such a machine learning approach improves the convergence of the Monte Carlo algorithm for high precision evaluation of multi-dimensional integrals compared to traditional algorithms. In particular, we use a neural network to improve the importance sampling. For a set of representative two-, three-, and four-loop integrals, that appear for example in the computation of the scattering angle for a binary encounter, we provide a quantitative comparison between the Monte Carlo integrator VEGAS and i-flow, an integrator based on neural network sampling. Furthermore, we present novel analytic results for static integrals relevant in the low-velocity limit.

description: The present study investigated the temporal distribution, accumulation, speciation and potential ecological risk of heavy metals in the sediment of an urban Yundang Lagoon catchment (YLC) at Xiamen in China. Total heavy metals concentration of Cr, Mn, Ni, Cu, Zn, As, Cd and Pb showed a significant seasonal variation in the sediment. Therefore, the average total metals concentration of Cr, Mn, Ni, Cu, Zn, As, Cd and Pb was 61.95, 529.95, 28.03, 64.95, 351.22, 10.29, 1.38 and 56.30 mg/kg for spring; 66.78, 501.22, 30.55, 67.72, 326.42, 10.91, 0.89 and 58.12 mg/kg for summer; 64.87, 472.80, 24.09, 66.26, 323.40, 5.51, 0.64 and 58.68 mg/kg for autumn; 82.36, 1589.05, 27.27, 82.64, 369.31, 11.79, 0.60 and 562.24 mg/kg for winter, respectively. Temporal metals speciation indicates a considerable seasonal variation of metal fraction concentrations. Igeo values have indicated considerable seasonal variation of pollution sources in the sediment of YLC. The temporal pollution load index indicates that winter sediment has the highest pollution load than other seasons.

description: Simple schematic showing the basic construction parameters of the FlyBox activity monitor, based on a design by Araujo et al., 2020.
 The FlyBox was constructed primarily from 1/2" plywood, spraypainted matt black to reduce light reflection. All joints were sealed with black silicone to prevent light penetration. The lid is hinged, and includes a latching mechanism which prevents the box from being opened accidentally during experiments. Gaps in the lid were sealed with foam weather stripping to prevent light penetration. In the lower compartment, ~2" wide holes were drilled on either side and enclosed by 90-degree black PVC elbow connectors. This provided ventilation to the lower compartment, keeping the infrared spotlight cool while preventing light penetration into the lower compartment. A 1/8" thick piece of clear acrylic panel was used to separate the upper and lower compartments, while still allowing the infrared spotlight to illuminate the mosquito plate from below. Infrared illumination from the spotlight was diffused using a lighting diffuser film sheet.

description: The spallation neutrons were produced by the irradiation of Pb with 250 MeV protons. The Pb target was surrounded by water which was used to slow down the emitted neutrons. The moderated neutrons in the water bath were measured by using the resonance detectors of Au, Mn and In with Cd cover. According to the measured activities of the foils, the neutron flux at different resonance energy were deduced and the epithermal neutron spectra were proposed. Corresponding results calculated with the Monte Carlo code MCNPX were compared with the experimental data to check the validity of the code.
