description: The juvenile form of neuronal ceroid Lipofuscinosis (JNCL) is the most common form within this group of rare lysosomal storage disorders, causing pediatric neurodegeneration. The genetic disorder, which is caused by recessive mutations affecting the CLN3 gene, features progressive vision loss, cognitive and motor decline, seizure episodes and other psychiatric conditions, leading to premature death. Animal models have traditionally aid the understanding of the disease mechanisms and pathology and are very relevant for biomarker research and therapeutic testing. Nevertheless, there is a need for establishing reliable and predictive human cellular models to study the disease. Since patient material, particularly from children, is scarce and difficult to obtain, we generated an engineered CLN3-mutant isogenic human induced pluripotent stem cell (hiPSC) line carrying the c.1054C→T pathologic variant, using state of the art CRISPR/Cas9 technology. To prove the suitability of the isogenic pair to model JNCL, we screened for disease-specific phenotypes in non-neuronal two-dimensional cell culture models as well as in cerebral brain organoids. Our data demonstrate that the solely introduction of the pathogenic variant gives rise to the classical hallmarks of JNCL in vitro. Additionally, we discovered an alteration of the splicing caused by this particular mutation. Next, we derived cerebral organoids and used them as a neurodevelopmental model to study the particular effects of the CLN3Q352X mutation during brain formation in the disease context. About half of the mutation carrying cerebral organoids completely failed to develop normally. The other half, which escaped this severe defect were used for the analysis of more subtle alterations. In these escapers whole-transcriptome analysis demonstrated early disease signatures, affecting pathways related to development, corticogenesis and synapses. Complementary metabolomics analysis confirmed decreased levels of cerebral tissue metabolites, some particularly relevant for synapse formation and neurotransmission, such as gamma-amino butyric acid (GABA). Our data suggests that a mutation in CLN3 severely affects brain development. Furthermore, before disease onset, disease associated neurodevelopmental changes, particular concerning synapse formation and function, occur.

description: With the advent of detectors with sub-keV sensitivities, atomic ionization has been identified as a promising avenue to probe possible neutrino electromagnetic properties. The interaction cross-sections induced by millicharged neutrinos are evaluated with the ab-initio multi-configuration relativistic random-phase approximation. There is significant enhancement at atomic binding energies compared to that when the electrons are taken as free particles. Positive signals would distinctly manifest as peaks at specific energies with known intensity ratios. Selected reactor neutrino data with germanium detectors at analysis threshold as low as 300 eV are studied. No such signatures are observed, and a combined limit on the neutrino charge fraction of | \numq | < 1.0 X 10^{-12} at 90% confidence level is derived.

description: We study the efficiency of random search processes based on L{é}vy flights with power-law distributed jump lengths in the presence of an external drift, for instance, an underwater current, an airflow, or simply the bias of the searcher based on prior experience. While Lévy flights turn out to be efficient search processes when relative to the starting point the target is upstream, in the downstream scenario regular Brownian motion turns out to be advantageous. This is caused by the occurrence of leapovers of L{é}vy flights, due to which L{é}vy flights typically overshoot a point or small interval. Extending our recent work on biased LF search [V. V. Palyulin, A. V. Chechkin, and R. Metzler, Proc. Natl. Acad. Sci. USA, DOI:10.1073/pnas.1320424111] we establish criteria when the combination of the external stream and the initial distance between the starting point and the target favors L{é}vy flights over regular Brownian search. Contrary to the common belief that L{é}vy flights with a L{é}vy index $α=1$ (i.e., Cauchy flights) are optimal for sparse targets, we find that the optimal value for $α$ may range in the entire interval $(1,2)$ and include Brownian motion as the overall most efficient search strategy.

description: A major challenge in the field of neurodegenerative diseases is the poor translation of pre-clinical models to clinical applications.  The human brain is an immensely complex structure, which makes it difficult to recapitulate its development, function and disorders. In the recent years, brain organoids derived from human induced pluripotent stem cells have risen as novel tools to study neurodegenerative diseases such as Parkinson’s disease (PD). PD is a multifactorial disorder, with aging, genetics and environmental factors as key etiological elements. The majority of the PD cases are idiopathic and proposed to result from a complex interaction between genetic predisposition and environmental exposure. Consequently, the identification of potentially disease causing environmental factors is of critical importance. Organoids, as complex multi-cellular tissue proxies, are an ideal tool to study cellular response to environmental changes. However, with increasing complexity of the system, usage of quantitative tools becomes challenging. This motivated us to develop an automated high-content image analysis pipeline for image-based cell profiling in the organoid system. Here, we introduce a neurotoxin-induced midbrain organoid system that recapitulates features of PD, representing a platform for machine-learning-assisted prediction of neurotoxicity in high-content imaging data. This model is a valuable tool for advanced in vitro PD modeling and for the screening of putative neurotoxic and neuroprotective compounds.

description: pypet (Python parameter exploration toolkit) is a new multi-platform Python toolkit for managing numerical simulations. Sampling the space of model parameters is a key aspect of simulations and numerical experiments. pypet is designed to allow easy and arbitrary sampling of trajectories through a parameter space beyond simple grid searches. pypet collects and stores both simulation parameters and results in a single HDF5 file. This collective storage allows fast and convenient loading of data for further analyses. pypet provides various additional features such as multiprocessing and parallelization of simulations, dynamic loading of data, integration of git version control, and supervision of experiments via the electronic lab notebook Sumatra. pypet supports a rich set of data formats, including native Python types, Numpy and Scipy data, Pandas DataFrames, and BRIAN(2) quantities. Besides these formats, users can easily extend the toolkit to allow customized data types. pypet is a flexible tool suited for both short Python scripts and large scale projects. pypet's various features, especially the tight link between parameters and results, promote reproducible research in computational neuroscience and simulation-based disciplines.

description: Conformally compactified (3+1)-dimensional Minkowski spacetime may be identified with the projective light cone in (4+2)-dimensional spacetime. In the latter spacetime the special conformal group acts via rotations and boosts, and conformal inversion acts via reflection in a single coordinate. Hexaspherical coordinates facilitate dimensional reduction of Maxwell electromagnetic field strength tensors to (3+1) from (4 + 2) dimensions. Here we focus on the operation of conformal inversion in different coordinatizations, and write some useful equations. We then write a conformal invariant and a pseudo-invariant in terms of field strengths; the pseudo-invariant in (4+2) dimensions takes a new form. Our results advance the study of general nonlinear conformal-invariant electrodynamics based on nonlinear constitutive equations.

description: Mitochondria as the main energy suppliers of eukaryotic cells are highly dynamic organelles that fuse, divide and are transported along the cytoskeleton to ensure cellular energy homeostasis. While these processes are well established, substantial evidence indicates that the internal structure is also highly variable in dependence on metabolic conditions. However, a quantitative mechanistic understanding of how mitochondrial morphology affects energetic states is still elusive.  To address this question, we here present an agent-based dynamic model using three-dimensional morphologies from electron microscopy tomography which considers the molecular dynamics of the main ATP production components. We apply our modeling approach to mitochondria at the synapse which is the largest energy consumer within the brain. Interestingly, comparing the spatiotemporal simulations with a corresponding space-independent approach, we find minor space dependence when the system relaxes toward equilibrium but a qualitative difference in fluctuating environments. These results suggest that internal mitochondrial morphology is not only optimized for ATP production but also provides a mechanism for energy buffering and may represent a mechanism for cellular robustness.
Transition from amplitude to oscillation death under mean-field diffusive coupling

description: We study the transition from amplitude death (AD) to oscillation death (OD) state in limit-cycle oscillators coupled through mean-field diffusion. We show that this coupling scheme can induce an important transition from AD to OD even in {\it identical} limit cycle oscillators. We identify a parameter region where OD and a novel {\it nontrivial} AD (NT-AD) state coexist. This NT-AD state is unique in comparison with AD owing to the fact that it is created by a subcritical pitchfork bifurcation, and parameter mismatch does not support but destroy this state. We extend our study to a network of mean-field coupled oscillators to show that the transition scenario preserves and the oscillators form a two cluster state.

description: The number of overseas finalists in the Business School of the University of Huddersfield has increased recently particularly from the European Union, including the new accession states. While the level of functional English of students is acceptable, they are inadequately prepared for study in English, given that they are expected to complete a final year dissertation that requires the acquisition of new skills. Student time in the final year is restricted and the main challenge is to provide useful learning opportunities within a limited timescale. A critical pragmatic approach has been adopted in developing a programme of writing skills support which enables students to adapt quickly to the demands of study at final year undergraduate level. The approach follows a pragmatic tradition but recognises the importance of critical skills and the necessity to practice of such skills. Quantitative research into student attendance and achievement indicates that this approach has had a positive impact while findings indicate that this approach to academic writing might be beneficial in similar settings.
Higher spin entanglement entropy from CFT

description: We consider free fermion and free boson CFTs in two dimensions, deformed by a chemical potential $μ$ for the spin-three current. For the CFT on the infinite spatial line, we calculate the finite temperature entanglement entropy of a single interval perturbatively to second order in $μ$ in each of the theories. We find that the result in each case is given by the same non-trivial function of temperature and interval length. Remarkably, we further obtain the same formula using a recent Wilson line proposal for the holographic entanglement entropy, in holomorphically factorized form, associated to the spin-three black hole in SL(3, R) x SL(3, R) Chern-Simons theory. Our result suggests that the order $μ^2$ correction to the entanglement entropy may be universal for W-algebra CFTs with spin-three chemical potential, and constitutes a check of the holographic entanglement entropy proposal for higher spin theories of gravity in AdS_3.

description: Spectroscopy of family gauge bosons is investigated based on a U(3) family gauge boson model proposed by Sumino. In his model, the family gauge bosons are in mass eigenstates in a diagonal basis of the charged lepton mass matrix. Therefore, the family numbers are defined by $(e_1,e_2, e_3)=(e, μ, τ)$, while the assignment for quark sector are free. For possible family-number assignments $(q_1, q_2, q_3)$, under a constraint from $K^0$-$\bar{K}^0$ mixing, we investigate possibilities of new physics, e.g. production of the lightest family gauge boson at the LHC, $μ^- N \rightarrow e^- N$, rare $K$ and $B$ decays, and so on.

Furthermore, we show that the conjecture holds in two dimensions provided that the boundary parameter is small.

description: In recent years, controlled dissipation has proven to be a useful tool for probing of a quantum system in the ultracold setup. In this paper we consider dynamics of bosons induced by a dissipative local defect. We address superfluid and supersolid phases close to half-filling that are ground states of an extended Bose-Hubbard Hamiltonian. To this end, we solve the master equation using the Gutzwiller approximation and find that in the superfluid phase repulsive nearest neighbour interactions can lead to enhanced dissipation processes. On the other hand, our mean-field approach indicates that the effective loss rates are significantly suppressed deep in the supersolid phase where repulsive nearest neighbour interactions play a dominant role. Our numerical results are explained by analytical arguments and in particular, in the limit of strong dissipation we recover the quantum Zeno effect.

title: Decadal variability of tropical cyclones in the Northern Hemisphere: natural variability or anthropogenic influence?
Creators: name: Loizou, Pinelopi
Publisher: name: University of Reading
Year: 2022

description: Understanding which environmental processes are responsible for driving the interannual and decadal variability of tropical cyclones (TCs) is important for providing TC impact-related mitigation and planning information to the responsible agencies and business. TC activity in the northern hemisphere is examined in IBTrACS, seven recent reanalyses and coupled and atmosphere-only simulations at various resolutions from HadGEM3-GC3.1. Drivers of TC activity are examined for the current climate, on decadal time scales and in scenarios of a warming climate. Different tools, including the standard power spectrum method, the wavelets, and the Empirical Teleconnections method are utilized. TC activity in the North Atlantic (NATL), characterized by high variability, is primarily influenced on interannual and decadal time scales by the Atlantic Multi-decadal Oscillation (AMO) via warm local Sea Surface Temperatures (SSTs). The primary driver for TC activity in the Eastern Pacific (EPAC) and Central Pacific (CPAC) regions under current climate conditions is the El-Niño Southern Oscillation (ENSO) with associated warm SSTs and weak Vertical Wind Shear (VWS) in the Pacific, whereas decadal variability is driven by both ENSO and AMO. Typhoon activity in the Western Pacific (WPAC) is found to be driven by more than one main driver in observations and the model. Variability of TC activity in the North Indian Ocean (NIND) is not linked significantly to the climate modes (ENSO, AMO, PDO) examined in the study. With a warming climate, ACE increases in NATL, EPAC, CPAC and WPAC and decreases for NIND. For EPAC there is a westward shift, while for WPAC there is a poleward shift in TC activity. Finally, a simple, open-source hurricane-catastrophe model is developed for assessing risk associated with hurricane winds for Bermuda and it is used to test the sensitivity of hurricane wind risk to variability of the frequency of events, particularly related to the AMO.

description: Abstract
Purpose: The prevalence of Covid-19 is an unprecedented challenge for health education systems, especially medical students (nursing and medical). Our aim is to evaluate the psychological impact of this outbreak on nursing and medical students studying at Guilan University of Medical Sciences. Design: This analytical-cross-sectional study was carried out in a convenient form in the second half of the year 2021 on nursing and medical internship students. Methods: Data required were gathered by Demographic Questionnaire, online COVID-19 Fear, and COVID-19 Anxiety Tools. Data were analyzed by SPSS software (version 16). The significance level of the tests was p˂0.05. Results: The mean total scores of fear and anxiety caused by COVID-19 were 14.22±4.31 and 8.28±6.64. There was a positive and significant correlation between the fear score and the total score of anxiety caused by COVID-19 (P=0.001, r=0.717); and a positive and significant correlation between fear scores and the score of the subscales of physical (P=0.001, r=0.521), and mental (P=0.001, r=0.717) anxiety. As well, there was a statistically significant relationship between the score of fear caused by COVID-19 and the variables of the female gender, occupation as a student, and the history of the development of COVID-19. There was a statistically significant relationship between the anxiety caused by COVID-19 and the variables of the female gender, occupation as a student, and educational major. Conclusions: Findings indicated that nursing and medical students were exposed to mental health problems due to fear and anxiety from the pandemic, and should undergo periodic mental health evaluations.

description: This study investigates how transcranial alternating current stimulation (tACS) affects cognitive performance across different chronotypes and genders. Using a semi-experimental design with 96 university students, researchers examined tACS's impact on executive functions and arousal vigilance during both optimal and non-optimal performance times. The study demonstrates that 10 Hz alpha frequency tACS applied to the DLPFC region particularly influences arousal during non-optimal times for both morning and evening chronotypes, with specific effects on executive function observed in morning chronotypes during non-optimal periods. These findings contribute to our understanding of how brain stimulation interventions interact with individual chronobiological differences, suggesting potential applications for cognitive enhancement that consider timing and personal chronotype.

description: In the simplest type-I seesaw leptogenesis scenario right-handed neutrino annihilation processes are absent. However, in the presence of new interactions these processes are possible and can affect the resulting $B-L$ asymmetry in an important way. A prominent example is provided by models with spontaneous lepton number violation, where the existence of new dynamical degrees of freedom can play a crucial role. In this context, we provide a model-independent discussion of the effects of right-handed neutrino annihilations. We show that in the weak washout regime, as long as the scattering processes remain slow compared with the Hubble expansion rate throughout the relevant temperature range, the efficiency can be largely enhanced, reaching in some cases maximal values. Moreover, the $B-L$ asymmetry yield turns out to be independent upon initial conditions, in contrast to the "standard" case. On the other hand, when the annihilation processes are fast, the right-handed neutrino distribution tends to a thermal one down to low temperatures, implying a drastic suppression of the efficiency which in some cases can render the $B-L$ generation mechanism inoperative.

description: The two-pion contribution from low energies to the muon magnetic moment anomaly, although small, has a large relative uncertainty since in this region the experimental data on the cross sections are neither sufficient nor precise enough. It is therefore of interest to see whether the precision can be improved by means of additional theoretical information on the pion electromagnetic form factor, which controls the leading order contribution. In the present paper we address this problem by exploiting analyticity and unitarity of the form factor in a parametrization-free approach that uses the phase in the elastic region, known with high precision from the Fermi-Watson theorem and Roy equations for $ππ$ elastic scattering as input. The formalism also includes experimental measurements on the modulus in the region 0.65-0.70 GeV, taken from the most recent $e^+e^-\to π^+π^-$ experiments, and recent measurements of the form factor on the spacelike axis. By combining the results obtained with inputs from CMD2, SND, BABAR and KLOE, we make the predictions $a_μ^{ππ, \LO}\,[2 m_π,\, 0.30 \gev]=(0.553 \pm 0.004) \times 10^{-10}$ and $a_μ^{ππ, \LO}\,[0.30 \gev,\, 0.63 \gev]=(133. 083 \pm 0.837)\times 10^{-10}$. These are consistent with the other recent determinations, and have slightly smaller errors.

description: Under the application of a force, a material will deform and, hence, the crystal lattice will experience strain. This induced strain will alter the electronic properties of the material. In particular, strain in graphene generates an artificial vector potential which, if spatially varying, admits a pseudo-magnetic field. Current theories for spatially varying strain use linear or finite strain theory whose derivation is based on small displacements of infinitesimal length vectors. Here we apply a differential geometry method to derive a strain theory for large displacements of finite length vectors. This method gives a finite displacement term whose contribution is comparable to that of the linear strain term. Further to this, we show that a 'domain wall'-like pseudo-magnetic field profile can be generated when a wide graphene ribbon is subjected to a pair of opposing point forces (point stretch). The resulting field is a function of the new finite displacement term only and displays a maximum strength of over three times that which is predicted by the linear strain theory. These results extend the current theories of strain, which are based on the transformation of infinitesimal length vectors, to finite length vectors, thus providing an accurate description of pseudo-magnetic field structures in strained materials.

description: AD-DMKDE is a novel anomaly detection method that combines density matrices (a mathematical formalism from quantum mechanics) and Fourier features. The method can be seen as an efficient approximation of Kernel Density Estimation (KDE) . AD-DMKDE was systematically compared against eleven state-of-the-art anomaly detection methods on a variety of benchmark data sets, showing competitive performance . The method uses optimization in order to find the parameters of data embedding. Its architecture can be easily implemented on GPU/TPU hardware. % . The prediction stage complexity of AD-DMKDE is constant relative to the training data size, in contrast with KDE, and it performs well in data sets with different anomaly rates

description: Providing quality medical education in Sudan faces challenges due to armed conflicts. This short communication explores practical solutions for ensuring the continuity of medical education during the conflict in the Sudanese context. Methods: A comprehensive literature review covered relevant articles published from 1915 to 2023. Four major databases (PubMed, Scopus, Web of Science, and Google Scholar) were searched using keywords related to medical education, war, armed conflict, and affected countries. Data synthesis identified common themes, challenges, and trends and suggested solutions for medical education in conflict zones. Case studies from Ukraine, Liberia, and Iraq were included for a comprehensive understanding. Results: Collaborative alliances among medical schools facilitate resource sharing and support. Engaging the Sudanese diaspora through virtual collaborations, mentorship programs, and faculty exchanges enhance educational experiences. Stable regions as educational hubs ensure uninterrupted academic progress for students from conflict-affected areas. Online and remote education, including asynchronous learning and social media platforms, overcome access barriers and fosters knowledge sharing. Ambulatory teaching provides practical experience and adaptability. Prioritizing faculty well-being and professional development through training and support is crucial. Emphasizing resilience and adaptability in student education prepare them for healthcare delivery in resource-limited settings. Research and innovation contribute to evidence-based strategies. International collaboration and support offer opportunities for knowledge exchange and infrastructure improvement. Conclusion: Implementing collaborative strategies and innovative approaches helps Sudanese medical schools overcome challenges during armed conflicts and maintain quality medical education. These solutions empower students and faculty, enhance resilience, and contribute to improving healthcare systems in post-war Sudan.

Z-Z' Mixing and Z-Mediated FCNCs in SU(3)_C x SU(3)_L x U(1)_X Models

description: Most of the existing analyses of FCNC processes in the 331 models, based on the gauge group SU(3)_C x SU(3)_L x U(1)_X, take only into account tree-level exchanges of a new heavy neutral gauge boson Z'. However due to the Z-Z' mixing also corresponding contributions from Z boson are present that are usually neglected. We calculate the impact of these contributions on Delta F=2 processes and rare K, B_s and B_d decays for different values of a parameter beta, which distinguishes between various 331 models and for different fermion representations under the SU(3)_L group. We find a general expression for the Z-Z' mixing in terms beta, M_Z, M_Z' and tan(bar{beta}), familiar from 2 Higgs Doublet models, that differs from the one quoted in the literature. We study in particular the models with beta=+-n/sqrt{3} with n=1,2 which have recently been investigated by us in the context of new data on B_{s,d}->mu^+ mu^- and B_d->K^*(K)mu^+ mu^-. We find that these new contributions can indeed be neglected in the case of Delta F=2 transitions and decays, like B_d->K^*mu^+mu^-, where they are suppressed by the small vectorial Z coupling to charged leptons. However the contributions of tree-level Z exchanges to decays sensitive to axial-vector couplings, like B_{s,d}->mu^+ mu^- and B_d->K mu^+ mu^-, and those with neutrinos in the final state, like b->s nu bar{nu} transitions, K^+->pi^+ nu bar{nu} and K_L->pi^0 nu bar{nu} cannot be generally neglected with size of Z contributions depending on beta, tan(bar{beta}) and M_Z'. We analyze for the first time the ratio epsilon'/epsilon in these models including both Z' and Z contributions. Our analysis of electroweak precision observables within 331 models demonstrates transparently that the interplay of NP effects in electroweak precision observables and those in flavour observables could allow in the future to identify the favourite 331 model.

Anomaly Detection
Quantum Machine Learning

description: Anomaly detection is an important task in several applications. Classical approaches, such as the isolation forest, suffer with high-dimensional data such as images. Deeper models, such as autoencoders, do not directly optimize an anomaly loss function, but exploit the proxy task by optimizing the reconstruction error. In this paper, we propose a new anomaly detection algorithm using autoencoders, adaptive Fourier features and density matrices. Autoencoders enable deep representation and can be coupled to other deep architectures such as convolutional neural networks. Adaptive Fourier features map the encoded representation to a higher dimension. Density matrices capture classical and quantum probability. The method produced a degree of normality based on density estimation and can be trained end-to-end using recent deep learning techniques. The method is on par with or outperforms other state-of-the-art methods. The novel method can be trained using gradient descent and graphics processing units (GPUs).

description: We provide a phenomenological formula which describes the low-frequency optical absorption of charge carriers in disordered systems with localization. This allows to extract, from experimental data on the optical conductivity, the relevant microscopic parameters determining the transport properties, such as the carrier localization length and the elastic and inelastic scattering times. This general formula is tested and applied here to organic semiconductors, where dynamical molecular disorder is known to play a key role in the transport properties. The present treatment captures the basic ideas underlying the recently proposed transient localization scenario for charge transport, extending it from the d.c. mobility to the frequency domain. When applied to existing optical measurements in rubrene FETs, our analysis provides quantitative evidence for the transient localization phenomenon. Possible applications to other disordered electronic systems are briefly discussed.
