Neurodegeneration with Brain Iron Accumulation: Two Additional Cases with Dystonic Opisthotonus
Creators: name: Mehta, Sahil

Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2019

description: Background: Specific phenomenology and pattern of involvement in movement disorders point toward a probable clinical diagnosis. For example, forehead chorea usually suggests Huntington’s disease; feeding dystonia suggests neuroacanthocytosis and risus sardonicus is commonly seen in Wilson’s disease. Dystonic opisthotonus has been described as a characteristic feature of neurodegeneration with brain iron accumulation (NBIA) related to PANK2 and PLA2G6 mutations. Case report: We describe two additional patients in their 30s with severe extensor truncal dystonia causing opisthotonic posturing in whom evaluation revealed the diagnosis of NBIA confirmed by genetic testing. Discussion: Dystonic opisthotonus may be more common in NBIA than it is reported and its presence especially in a young patient should alert the neurologists to a possibility of probable NBIA.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Single chlorophyll-a molecules, a vital resource for the sustenance of life on Earth, have been investigated by using scanning-tunneling-microscope manipulation and spectroscopy on a gold substrate at 4.6 K. The chlorophyll-a binds on Au(111) via its porphyrin unit while the phytyl-chain is elevated from the surface by a support of four CH3 groups. By injecting tunneling electrons from the STM-tip, we are able to bend the phytyl-chain, which enable switching of four molecular conformations in a controlled manner. Statistical analyses and structural calculations reveal that all reversible switching mechanisms are initiated by a single tunnelling-electron energy-transfer process, which induces bond rotation within the phytyl-chain.

description: We study the influence of a lossless material medium on the coherent storage and quantum state transfer of a quantized probe light in an ensemble of $Λ$-type atoms. The medium is modeled as uniformly distributed two-level atoms with same energy level spacing, coupling to a probe light. This coupled system can be simplified to a collection of two-mode polaritons which couple to one transition of the $Λ$-type atoms. We show that, when the other transition of $Λ$-type atoms is controlled by a classical light, the electromagnetically induced transparency can also occur for the polaritons. In this case the coherent storage and quantum transfer for photon states are achievable through the novel dark states with respect to the polaritons. By calculating the corresponding dispersion relation, we find the ensemble of the three-level atoms with $Λ$-type transitions may serve as quantum memory for it slows or even stops the light propagation through the mechanism of electromagnetically induced transparency. the corresponding dispersion relation, we find the ensemble of the three-level atoms with $Λ$-type transitions may serve as quantum memory for it slows or even stops the light propagation through the mechanism of electromagnetically induced transparency.

description: Weaving knots $W(p, n)$ of type $(p, n)$ denote an infinite family of hyperbolic knots which have not been addressed by the knot theorists as yet. Unlike the well-known $(p,n)$ torus knots, we do not have a closed-form expression for HOMFLY-PT and the colored HOMFLY-PT for $W(p,n)$. In this paper, we confine to a hybrid generalization of $W(3,n)$ which we denote as $\hat{W}_3(m,n)$ and obtain a closed-form expression for HOMFLY-PT using the Reshitikhin and Turaev method involving $\mathcal R$-matrices. Further, we also compute $[r]$-colored HOMFLY-PT for $W(3,n)$. Surprisingly, we observe that trace of the product of two dimensional $\hat{\mathcal{R}}$-matrices can be written in terms of an infinite family of Laurent polynomials $\mathcal{V}_{n,t}[q]$ whose absolute coefficients has an interesting relation to the Fibonacci numbers $\mathcal{F}_{n}$. We also computed reformulated invariants and the BPS integers in the context of topological strings. From our analysis, we propose that certain refined BPS integers for weaving knot $W(3,n)$ can be explicitly derived from the coefficients of Chebyshev polynomials of the first kind.

Metaphonological awareness and spelling ability
Creators: name: Roper, Catherine Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the present study was to investigate the relationship between metaphonological awareness and spelling ability. Twenty-five children in Kindergarten and Grades One and Two were asked to participate in two tasks of metaphonological awareness, one involving phoneme segmentation (Yopp,1988) and the other phoneme deletion (Rosner,1975). Children were also asked to provide self-generated spelling samples. Spelling samples were then analyzed according to a spelling assessment scheme developed for this study and based on the developmental spelling stages outlined by Beers and Beers (1981) and Gentry (1982). The major finding from this study is that some aspects of metaphonological ability are reliably and moderately related to spelling development. Other findings regard the characteristics of children's spelling errors observed in the course of developing the spelling assessment scheme.
High order finite volume schemes with IMEX time stepping for the Boltzmann model on unstructured meshes
Creators: name: Boscheri, Walter
name: Dimarco, Giacomo
Publisher: name: arXiv
Year: 2021
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: In this work, we present a family of time and space high order finite volume schemes for the solution of the full Boltzmann equation. The velocity space is approximated by using a discrete ordinate approach while the collisional integral is solved by spectral methods. The space reconstruction is realized by integrating the distribution function, describing the state of the system, over arbitrary shaped and closed control volumes using a Central Weighted ENO (CWENO) technique. Compared to other reconstruction methods, this approach permits to keep compact stencil sizes which is a remarkable property in the context of kinetic equations due to the considerable demand of computational resources. The full discretization is then obtained by combining the previous phase-space approximation with high order Implicit-Explicit (IMEX) Runge Kutta schemes. These methods guarantee stability, accuracy and preservation of the asymptotic state. Comparisons of the Boltzmann model with simpler relaxation type kinetic models (like BGK) is proposed showing the capability of the Boltzmann equation to capture different physical solutions. The theoretical order of convergence is numerically measured in different regimes and the methods are tested on several standard two-dimensional benchmark problems in comparison with Direct Simulation Monte Carlo results. The article ends with a prototype engineering problem consisting of a subsonic and a supersonic flow around a NACA 0012 airfoil. All test cases are run with MPI parallelization on several threads, thus making the proposed methods suitable for parallel distributed memory supercomputers.
Angular Diameter Distance Measurement with Galaxy Clustering in the Multipole Space
Creators: name: Cooray, Asantha
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The shape of the angular power spectrum of galaxies in the linear regime is defined by the horizon size at the matter-radiation equality. When calibrated by cosmic microwave background measurements, the shape of the clustering spectrum can be used as a standard ruler to estimate angular diameter distance as a function of redshift at which galaxy clustering is measured. We apply the proposed cosmological test of Cooray et al. (2001) to a recent set of luminous red galaxy angular clustering spectra from the Sloan Digital Sky Survey between redshifts of 0.2 and 0.6. Using the overall shape of the clustering power spectrum in the linear regime, w e measure comoving angular diameter distances to eight redshift bins by marginalizing over the bias factors that determine the overall amplitude of the clustering spectrum in each of the bins. The Hubble constant consistent with these distance estimates is 68.5^+6.7_-6.1 km s^-1 Mpc-1 at the 68% confidence level. We comment on the expected improvements with future surveys and the potential to measure dark energy parameters with this method.

description: Recently, deep Reinforcement Learning (RL) algorithms have achieved dramatically progress in the multi-agent area. However, training the increasingly complex tasks would be time-consuming and resources-exhausting. To alleviate this problem, efficient leveraging the historical experience is essential, which is under-explored in previous studies as most of the exiting methods may fail to achieve this goal in a continuously variational system due to their complicated design and environmental dynamics. In this paper, we propose a method, named "KnowRU" for knowledge reusing which can be easily deployed in the majority of the multi-agent reinforcement learning algorithms without complicated hand-coded design. We employ the knowledge distillation paradigm to transfer the knowledge among agents with the goal to accelerate the training phase for new tasks, while improving the asymptotic performance of agents. To empirically demonstrate the robustness and effectiveness of KnowRU, we perform extensive experiments on state-of-the-art multi-agent reinforcement learning (MARL) algorithms on collaborative and competitive scenarios. The results show that KnowRU can outperform the recently reported methods, which emphasizes the importance of the proposed knowledge reusing for MARL.

description: Background: The prevalence of dystonia varies worldwide. A prior report suggested a high prevalence of focal dystonia in the Faroese population, possibly reflecting a founder effect. During standardized neurological examination as part of an ongoing neuroepidemiologic study in the Faroe Islands, we noted an unusual phenomenon of thumb flexion during repetitive hand movements in a subset of subjects and sought to define its phenomenology. Methods: We requested commentary from a panel of dystonia experts regarding the phenomenology of the movements. These experts reviewed the videotaped neurological examination. Results: Among the experts, dystonia was the leading diagnosis. Alternate causes were considered, but deemed less likely. Discussion: Diagnosis of dystonia requires careful clinical assessment and consideration of associated features. We report a novel form of dystonia, not previously described to our knowledge, in this isolated population. Further studies of dystonia prevalence in the Faroe Islands are merited to characterize its burden in this population and its specific clinical characteristics.

description: We investigate ultrafast phonon dynamics in the Bi$_{1-x}$Sb$_{x}$ alloy system for various compositions $x$ using a reflective femtosecond pump-probe technique. The coherent optical phonons corresponding to the A$_{1g}$ local vibrational modes of Bi-Bi, Bi-Sb, and Sb-Sb are generated and observed in the time domain with a few picoseconds dephasing time. The frequencies of the coherent optical phonons were found to change as the Sb composition $x$ was varied, and more importantly, the relaxation time of those phonon modes was dramatically reduced for $x$ values in the range 0.5--0.8. We argue that the phonon relaxation dynamics are not simply governed by alloy scattering, but are significantly modified by anharmonic phonon-phonon scattering with implied minor contributions from electron-phonon scattering in a Weyl-semimetal phase.

description: Background: Primary orthostatic tremor (POT) remains a therapeutic conundrum. Various medication classes have been tried, yielding modest results at best. Case Report: A 62-year-old female with a 13-year history of POT, refractory to clonazepam up to 20 mg/day, was treated with perampanel 1–2 mg/day. She reported 90% subjective symptomatic improvement. Discussion: This case highlights the potential for use of perampanel, a novel AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptor antagonist for the treatment of POT. There has been one prior report citing its use for POT with complete resolution of symptoms. We encourage further studies to highlight its efficacy for POT.

Quantum dynamics of the dissipative two-state system coupled with a sub-Ohmic bath

description: The decoherence of a two-state system coupled with a sub-Ohmic bath is investigated theoretically by means of the perturbation approach based on a unitary transformation. It is shown that the decoherence depends strongly and sensitively on the structure of environment. Nonadiabatic effect is treated through the introduction of a function $ξ_k$ which depends on the boson frequency and renormalized tunneling. The results are as follows:(1) the non-equilibrium correlation function $P(t)$, the dynamical susceptibility $χ''(ω)$ and the equilibrium correlation function $C(t)$ are analytically obtained for $s\leq 1$; (2) the phase diagram of thermodynamic transition shows the delocalized-localized transition point $α_l$ which agrees with exact results and numerical data from the Numerical Renormalization Group; (3) the dynamical transition point $α_c$ between coherent and incoherent phase is explicitly given for the first time. A crossover from the coherent oscillation to incoherent relaxation appears with increasing coupling (for $α> α_c $, the coherent dynamics disappear); (4) the Shiba's relation and sum rule are exactly satisfied when $α\leq α_c $; (5) an underdamping-overdamping transition point $α_c^{*}$ exists in the function $S(ω)$. Consequently, the dynamical phase diagrams in both ohmic and sub-Ohmic case are mapped out. For $Δ\ll ω_c$, the critical couplings ($α_l, α_c$ and $α_c^{*}$) are proportional to $Δ^{1-s}$.

Evaluation of an automated on-line bedside nurse documentation system
Creators: name: Robinson, Carol J.
Publisher: name: University of British Columbia
Year: 2010

description: In recent years there has been an increased emphasis on source data capture, point-of-care systems or bedside computing in the health care industry. Many of those involved in health care have speculated that bedside computing could contribute to efficient, cost effective health care delivery. The purpose of this quasi-experimental study was to evaluate the effect of a bedside automated online nurse documentation system using a methodology designed to overcome some of the difficulties of previous studies. The first of four objectives was to determine the effect of the automated system on nurse productivity. The second objective was to determine the effect of the system on some nursing behaviours that have been predictors of quality of care. The third objective of the study was to evaluate nurse satisfaction with on-line bedside computing. Evaluation of the acceptance of the bedside computer by the patients and their satisfaction with their care was the final objective. The automated bedside-based nurse documentation system was implemented on a twenty-two bed Plastic Surgery unit in a quaternary care teaching hospital. The automated nurse documentation system was developed by the hospital over a three year period (1986-1989). Four bedside computers were placed in a four bed experimental room; a second four bed room was used as the control room. Two terminals with access to the bedside-based system were located at the nursing station. Sixteen full time registered nurses participated in the study. The nurses used the automated bedside system when documenting care for patients in the experimental room and the manual, nursing station based, paper system to document care for patients in the control room. Questionnaires and observations were used to collect data over the four months of the study (June through September, 1990). The results showed no increase in nurse productivity. The quality of care results showed more immediate documentation of the nurses' observations and interventions and more time spent viewing patient data in the experimental state. There was no significant difference between the control and experimental state in the nurses' reported ability to provide individualized care. The nurses expressed a general level of dissatisfaction with the on-line bedside-based system and a general dissatisfaction with documenting at the patient bedside. The nurses found the manual system to be significantly more convenient than the automated system. In addition, the nurses found the presentation of patient data to be significantly better in the manual system. There was no significant difference between the reported satisfaction of patients with their care and their feelings and attitudes about the use of computers by nurses and in health care in the control and experimental rooms. The results of the study lead the investigator to explore implications for implementation of bedside computing for nurses.

Year: 2019

description: Background: Functional movement disorders (FMDs) have been rarely described in the elderly population. Methods: This is a retrospective chart review of elderly patients with FMDs (onset >60 years) attending the movement disorders clinic at a tertiary care teaching institute in India. Results: Out of 117 patients diagnosed with FMD at our center, 18 patients had an onset after the age of 60 years. The male-to-female ratio was 10:8 and the duration of symptoms ranged from 1 day to 5 years. Social (10/18) and physical factors (5/18) with an evident temporal relationship with the onset of FMD were identified in 15 out of 18 patients. Six of them had a past history of depression, anxiety, or other psychiatric illnesses. The tremor was the most frequent phenomenology seen in 11 (61.1%) patients, followed by dystonia in seven (38.8%), choreoballism and tics in two each, and hemifacial spasm and functional gait in one each. Seven patients had more than one phenotype. Discussion: Tremor was the most frequent movement disorder seen in our patients with FMD. Surprisingly, tics (n = 2) and choreoballistic (n = 2) movements were also found in our patients with FMD, which has not been reported previously in an elderly population. Both physical and social factors were identified preceding the development of FMDs in majority of our patients. Keywords: Functional, movement disorders, elderly, tremor, entrainment.

Logarithmic Relaxation in a Kinetically Constrained Model

description: We present Monte Carlo simulations in a modification of the north-or-east-or-front model recently investigated by Berthier and Garrahan [J. Phys. Chem. B 109, 3578 (2005)]. In this coarse-grained model for relaxation in supercooled liquids, the liquid structure is substituted by a three-dimensional array of cells. A spin variable is assigned to each cell, with values 0 or 1 denoting respectively unexcited and excited local states in a mobility field. Change in local mobility (spin flip) for a given cell is permitted according to kinetic constraints determined by the mobilities of neighboring cells. In this work we keep the same kinetic constraints of the original model, but we introduce two types of cells (denoted as "fast'' and "slow'') with very different rates for spin flip. As a consequence, fast and slow cells exhibit very different relaxation times for spin correlators. While slow cells exhibit standard relaxation, fast cells display anomalous relaxation, characterized by a concave-to-convex crossover in spin correlators by changing temperature or composition. At intermediate state points logarithmic relaxation is observed over three time decades. These results display striking analogies with dynamic correlators reported in recent simulations on a bead-spring model for polymer blends.

description: A classical dynamical model that treats break-up stochastically is presented for low energy reactions of weakly-bound nuclei. The three-dimensional model allows a consistent calculation of breakup, incomplete and complete fusion cross sections. The model is assessed by comparing the breakup observables with CDCC quantum mechanical predictions, which are found to be in reasonable agreement. Through the model, it is demonstrated that the breakup probability of the projectile as a function of its distance from the target is of primary importance for understanding complete and incomplete fusion at energies near the Coulomb barrier.

Shape Bistability in Squeezed Chromonic Droplets

description: We study droplets of chromonic liquid crystals squeezed between parallel plates inducing degenerate tangential anchoring on the nematic director. In the coexistence regime, where droplets in the nematic phase are at equilibrium with the surrounding melt, our two-dimensional theoretical model predicts a regime of shape bistability for sufficiently large bipolar droplets, where tactoids (pointed shapes) and discoids (smooth shapes) coexist in equilibrium. This phenomenon has not yet been observed. Two-dimensional droplets of disodium cromoglycate (DSCG) have been the object of a thorough experimental study [Y.-K. Kim et al., J. Phys.: Condens. Matter 25, 404202 (2013)]. We show that our theory is in good quantitative agreement with these data and extract from them what promises to be a more accurate estimate for the isotropic surface tension at the nematic/melt interface of DSCG.

description: Background: Botulinum neurotoxin’s degree of effectiveness on upper limb tremor is subject to debate; although this treatment reduces the tremor’s amplitude, a clear functional benefit has not been demonstrated. The objective of this study was to assess the effect of botulinum neurotoxin type A treatment on activities of daily living and quality of life in patients with upper limb tremor. Methods: We retrospectively examined the medical records of 50 consecutive patients treated with botulinum neurotoxin for upper limb tremor that was refractory to oral medication. One month after the injection, the patient was evaluated according to the Quality of Life in Essential Tremor Questionnaire, and the Essential Tremor Embarrassment Assessment. Results: Full data sets were available for 38 patients suffering variously from essential tremor (n = 21), Holmes tremor secondary to a focal brain lesion (n = 8), idiopathic dystonic tremor (n = 4), primary writing tremor (n = 4), and Parkinson’s disease (n = 1). The Quality of Life Essential Tremor Questionnaire and the Essential Tremor Embarrassment Assessment scores improved significantly (p < 0.001) in the study population as a whole, and in the essential tremor and Holmes tremor subgroups. Discussion: Botulinum neurotoxin treatment of patients with upper limb tremor is associated with improved quality of life and activities of daily living, irrespective of the tremor’s etiology. Long-term treatment enables the physician to adjust the injection strategy to the patient’s needs. Our study was limited by its retrospective design. The results must therefore be confirmed in a prospective, double-blind, placebo-controlled, randomized clinical trial.

Extended double seesaw model for neutrino mass spectrum and low scale leptogenesis

description: We consider a variant of seesaw mechanism by introducing extra singlet neutrinos, with which we show how the low scale leptogenesis is realized without imposing the tiny mass splitting between two heavy Majorana neutrinos required in the resonant leptogenesis. Thus, we can avoid the so-called gravitino problem when our scenario is supersymmetrized. We show that an introduction of the new singlet fermion leads to a new contribution which can enhance the lepton asymmetry for certain range of parameter space. We also examine how both the light neutrino mass spectrum and relatively light sterile neutrinos of order a few 100 MeV can be achieved without being in conflict with the constraints on the mixing between the active and sterile neutrinos.

description: We consider the Laplacian in a domain squeezed between two parallel curves in the plane, subject to Dirichlet boundary conditions on one of the curves and Neumann boundary conditions on the other. We derive two-term asymptotics for eigenvalues in the limit when the distance between the curves tends to zero. The asymptotics are uniform and local in the sense that the coefficients depend only on the extremal points where the ratio of the curvature radii of the Neumann boundary to the Dirichlet one is the biggest. We also show that the asymptotics can be obtained from a form of norm-resolvent convergence which takes into account the width-dependence of the domain of definition of the operators involved.

description: Several European countries have suspended the inoculation of the AstraZeneca vaccine out of suspicion of causing deep vein thrombosis. In this letter we report some Fermi estimates performed using a stochastic model aimed at making a risk-benefit analysis of the interruption of the delivery of the AstraZeneca vaccine in France and Italy. Our results clearly show that excess deaths due to the interruption of the vaccination campaign injections largely overrun those due to thrombosis even in worst case scenarios of frequency and gravity of the vaccine side effects.
