description: Chaotic transport is a subject of paramount importance in a variety of problems in plasma physics, specially those related to anomalous transport and turbulence. On the other hand, a great deal of information on chaotic transport can be obtained from simple dynamical systems like two-dimensional area-preserving (symplectic) maps, where powerful mathematical results like KAM theory are available. In this work we review recent works on transport barriers in area-preserving maps, focusing on systems which do not obey the so-called twist property. For such systems KAM theory no longer holds everywhere and novel dynamical features show up as non-resistive reconnection, shearless curves and shearless bifurcations. After presenting some general features using a standard nontwist mapping, we consider magnetic field line maps for magnetically confined plasmas in tokamaks.

description: Background: Tissue‐based research has recently led to a new patho‐mechanistic model of essential tremor (ET)—the cerebellar degenerative model. We are not aware of a study that has reviewed the current neuroimaging evidence, focusing on whether the studies support or refute the neurodegenerative hypothesis of ET. This was our aim. Methods: References for this review were identified by searches of PubMed (1966 to February 2014). Results: Several neuroimaging methods have been used to study ET, most of them based on magnetic resonance imaging (MRI). The methods most specific to address the question of neurodegeneration are MRI‐based volumetry, magnetic resonance spectroscopy, and diffusion‐weighted imaging. Studies using each of these methods provide support for the presence of cerebellar degeneration in ET, finding reduced cerebellar brain volumes, consistent decreases in cerebellar N‐acetylaspartate, and increased mean diffusivity. Other neuroimaging techniques, such as functional MRI and positron emission tomography (PET) are less specific, but still sensitive to potential neurodegeneration. These techniques are used for measuring a variety of brain functions and their impairment. Studies using these modalities also largely support cerebellar neuronal impairment. In particular, changes in 11C‐flumazenil binding in PET studies and changes in iron deposition in an MRI study provide evidence along these lines. The composite data point to neuronal impairment and likely neuronal degeneration in ET. Discussion: Recent years have seen a marked increase in the number of imaging studies of ET. As a whole, the combined data provide support for the presence of cerebellar neuronal degeneration in this disease.

description: Recently, intensive studies have revealed fascinating physics, such as charge density wave and superconducting states, in the newly synthesized kagome-lattice materials $A$V$_3$Sb$_5$ ($A$=K, Rb, Cs). Despite the rapid progress, fundamental aspects like the magnetic properties and electronic correlations in these materials have not been clearly understood yet. Here, based on the density functional theory plus the single-site dynamical mean-field theory calculations, we investigate the correlated electronic structure and the magnetic properties of the KV$_3$Sb$_5$ family materials in the normal state. We show that these materials are good metals with weak local correlations. The obtained Pauli-like paramagnetism and the absence of local moments are consistent with recent experiment. We reveal that the band crossings around the Fermi level form three groups of nodal lines protected by the spacetime inversion symmetry, each carrying a quantized $π$ Berry phase. Our result suggests that the local correlation strength in these materials appears to be too weak to generate unconventional superconductivity, and non-local electronic correlation might be crucial in this kagome system.

description: Background: Dystonia is a heterogeneous hyperkinetic disorder. The anatomical location of the dystonia helps clinicians guide their evaluation and treatment plan. When dystonia involves masticatory, lingual, and pharyngeal muscles, it is referred to as oromandibular dystonia (OMD). Methods: We identified patients diagnosed with OMD in a Movement Disorders Clinic and Laryngeal Movement Disorders Clinic from a single institution. Demographic, etiological, clinical, and therapeutic information was retrospectively reviewed for patients with jaw‐opening (O‐OMD) and jaw‐closing (C‐OMD) OMD. Results: Twenty‐seven patients were included. Their average age of onset was in the sixth decade of life and there was a female predominance. Etiological factors linked in this study to OMD included a family history of dystonia or essential tremor, occupation, cerebellar disease, a dental disorder, and tardive syndrome. Clinically, patients with C‐OMD presented with more prominent feeding difficulties, but seemed to respond better to therapy than those with O‐OMD. In addition to the known benefits of botulinum toxin therapy, patients who described sensory tricks obtained benefit from the use of customized dental prosthesis. Discussion: This works provides useful information on potential etiological factors for OMD and its response to therapy, and highlights the potential benefit of dental prosthesis for the treatment of OMD.

description: Background: Vivid descriptions of the phenomenology of focal task‐specific dystonia (FTSD) date back to the late nineteenth century. Methods: In this review, I summarize the natural history, phenomenology, and treatment of FTSD, focusing on nineteenth‐century neurologists' descriptions of the phenomenology, etiology, treatment, and mechanism. Results: Examining these texts through a twenty‐first‐century lens, the “modern” ideas of a dystonic endophenotype, disordered physiology, and dystonic metabolic networks actually appeared in these texts more than a century ago. Discussion: By incorporating these ideas with recent investigations, I present a new conceptual model for understanding this mysterious malady.

description: Background: The objective of this study was to identify important attributes associated with the triad of symptoms (cognition, emotional–behavioral, and motor) of Huntington's disease (HD) from patient, caregiver, and medical provider perspectives to facilitate development of a new disease‐specific, health‐related quality of life (HRQOL) instrument. Methods: We conducted a targeted literature review of HD and HRQOL instruments, expert surveys, and patient and caregiver phone‐based interviews to extract information on the symptoms and issues most relevant to the HD symptom triad (HD triad). The data collected from these sources were used to generate themes and subdomains and to develop an integrated schema that highlights the key dimensions of the triad. Results: The search identified the following areas: emotional functioning/behavioral changes (e.g., positive emotions, sadness/depression); cognitive functioning (e.g., memory/learning, attention/comprehension); physical functioning (e.g., motor functioning, medication); social functioning (e.g., leisure, interpersonal relationships); end‐of‐life concerns/planning; and gene testing. Fifteen individuals diagnosed with HD and 16 HD caregivers, recruited from several Huntington's Disease Society of America support group networks, completed phone interviews. Nineteen US medical providers who specialize in HD completed the online survey. Twenty‐six subdomains of the HD symptom triad (seven cognition, 12 emotional–behavioral, and seven motor) emerged relatively consistently across patient, caregiver, and provider samples. These included movements/chorea, memory impairment, depression, and anxiety. Discussion: Based on an integrated, mixed‐methods approach, important HD triad symptom were identified and organized into a guiding schema. These patient‐, caregiver‐, and provider‐triangulated data served as the basis for development of a HD‐specific HRQOL instrument, the HD‐PRO‐TRIAD™.

description: Background: Non‐motor symptoms (NMS) in Parkinson's disease (PD) differ from those in essential tremor (ET), even before a definitive diagnosis is made. It is not clear whether patient's knowledge of the diagnosis and treatment influence their subsequent reporting of NMS. Methods: 1 year after a clinical and instrumental diagnosis, we compared the motor impairment (Movement Disorders Society (MDS)‐Unified Parkinson's Disease Rating Scale‐III) and non‐motor symptoms (NMSQuest) in PD (n = 31) and ET (n = 21) patients. Results: PD patients reported more NMS than did the ET patients (p = 0.002). When compared to their baseline report, at follow‐up, PD patients reported less nocturia (p = 0.02), sadness (p = 0.01), insomnia (p = 0.02), and restless legs (p = 0.04) and more nausea (p = 0.024), unexplained pain (p = 0.03), weight change (p = 0.009), and daytime sleepiness (p = 0.03). When compared to their baseline report, ET patients reported less loss of interest (p = 0.03), anxiety (p = 0.006), and insomnia (p = 0.02). Differences in reported weight change (p<0.0001) and anxiety (p = 0.001) between PD and ET patients were related to pharmacological side effects or to a reduction in the ET individuals. Discussion: The reporting of NMS is influenced by subjective factors, and might vary with the patient's knowledge of the diagnosis or the effectiveness of treatment.

description: We study the phase-locking transition of two coupled low-dimensional superfluids, either two-dimensional superfluids at finite temperature, or one-dimensional superfluids at zero temperature. We find that the superfluids have a strong tendency to phase-lock. The phase-locking is accompanied by a sizeable increase of the transition temperature $T_{c}$ (in 2D systems) of the resulting double-layer superfluid to thermal Bose gas transition, compared to the Kosterlitz-Thouless temperature $T_{KT}$ of the uncoupled 2D systems, which suggests a plausible way of observing the Kibble-Zurek mechanism in two-dimensional cold atom systems by rapidly varying the tunneling rate between the superfluids. If there is also interaction between atoms in different layers present we find additional phases, while no sliding phase, characterized by order or quasi long range order (QLRO) either in the symmetric or the antisymmetric sector of the system.

description: The direct and indirect boundary element methods, accelerated via the fast multipole method, are applied to numerical simulation of room acoustics for large rooms of volume $\sim 150$ $m^{3}$ and frequencies up to 5 kHz on a workstation. As the parameter $kD$ (wavenumber times room diameter) is large, stabilization of the previously developed FMM algorithms is required for accuracy. A stabilization scheme is one of the key contribution of this paper. The computations are validated using well-known image source solutions for shoebox shaped rooms. Computations for L-shaped rooms are performed to illustrate the ability to capture diffractions. The ability to model in-room baffles, and boundary openings (doors/windows) is also demonstrated. The largest case has $kD>1100$ with a discretization of size 6 million elements. The performance of different boundary integral formulations was compared, and their rates of convergence using a preconditioned flexible GMRES were found to be substantially different. These promising results suggest a path to efficient simulations of room acoustics via high performance boundary element methods.

description: We introduce a generalization of local density of states which is "windowed" with respect to position and energy, called the windowed local density of states (wLDOS). This definition generalizes the usual LDOS in the sense that the usual LDOS is recovered in the limit where the position window captures individual sites and the energy window is a delta distribution. We prove that the wLDOS is local in the sense that it can be computed up to arbitrarily small error using spatial truncations of the system Hamiltonian. Using this result we prove that the wLDOS is well-defined and computable for infinite systems satisfying some natural assumptions. We finally present numerical computations of the wLDOS at the edge and in the bulk of a "Fibonacci SSH model", a one-dimensional non-periodic model with topological edge states.

description: Background: Several genes associated with dystonia have been identified. A mutation in one of these, THAP1 (DYT6), is linked to isolated dystonia. The aim of this study was to assess the prevalence of THAP1 gene mutations and the clinical characteristics of patients with these mutations in a clinical population in Brazil. Methods: Seventy‐four patients presenting with dystonia involving the cervical muscles and without mutations in the TOR1A (DYT1) gene or any other movement disorders were recruited at a movement disorders clinic between June 2008 and June 2009. All the patients underwent clinical examination and were screened for mutations of the THAP1 gene. Results: Three patients had the novel p.Gln97Ter THAP1 nonsense mutation in heterozygosis. One of them had no family history of dystonia. Symptoms in this patient first appeared in his right arm, and the condition progressed to the generalized form. The other two patients belonged to the same family (cousins). Symptoms in the first patient started in her right arm at the age of 18 years and the condition progressed to the segmental form. The second patient, who carried the p.Arg169Gln missense mutation, developed dystonia in her left arm at the age of 6 years. The condition progressed to generalized dystonia. Discussion: We conclude that THAP1 mutations are also a cause, albeit uncommon, of segmental and generalized dystonia in the Brazilian population.

description: Our scoping review aims to assess what legal, ethical, and socio-technical factors contribute or inhibit the success of national eHealth system implementations. In addition, our review seeks to describe the characteristics and benefits of eHealth systems. We conducted a scoping review of literature published in English between January 2000 and 2020 using a keyword search on five databases; PubMed, Scopus, Web of Science, IEEEXplore, and ProQuest. After removal of duplicates, abstract screening and full-text filtering, 86 articles were included from 8276 search results. We identified 17 stakeholder groups, 6 eHealth Systems areas, and 15 types of legal regimes and standards. In-depth textual analysis revealed challenges mainly in implementation, followed by ethico-legal and data related aspects. Key factors influencing success include promoting trust of the system, ensuring wider acceptance amongst users, reconciling the system with legal requirements and ensuring an adaptable technical platform. Results revealed support for decentralised implementations because they carry less implementation and engagement challenges than centralised ones. Simultaneously, due to decentralised systems interoperability issues, federated implementations (with a set of national standards) might be preferable. This study identifies the primary socio-technical, legal and ethical factors that challenge and contribute to the success of eHealth system implementations. This study also describes the complexities and characteristics of existing eHealth implementation programs, and surmises suggested guidance for resolving the identified challenges.

description: Data Champions (DCs) are volunteers who advise members of the research community at the University of Cambridge on proper handling of research data. In this, they promote good research data management (RDM) and support FAIR (Findable, Accessible, Interoperable, and Re-usable) research principles. DCs can be researchers (including graduate students), data managers, IT professionals, librarians, or data scientists. The programme is therefore an innovative way of cultivating good data practices across the University, including at the Yusuf Hamied Department of Chemistry where there is effectively a DC ‘hub’. Ultimately the DCs aim to influence a change from the existing, more closed research culture at the University to an open one. One example of trying to influence this change has been through an innovative and fun project to create DC cartoons for use as an advocacy tool for good practice in RDM. DCs undertook a stakeholder analysis exercise to try and work out: a) why RDM is of value to different stakeholders; b) their possible objections to RDM; and c) what responses a DC could formulate to these objections. The idea behind this was that if a DC was stuck in a lift, or sat next to someone at a college dinner or a meeting for example, and is having a conversation with them about RDM, and that person raised an objection to it, this could be rebutted with a suitable response prepared in advance. This presentation discusses the project timeline, and the challenges involved in creating a range of postcards featuring cartoon scenarios where DCs have an opportunity to advocate good practice in RDM.

description: We present a competition on text block segmentation within the framework of the International Conference on Pattern Recognition (ICPR) 2020. The main goal of this competition is to automatically analyse the structure of historical newspaper pages with a subsequent evaluation of the participants’ algorithms performance. In contrast to many existing segmentation methods, instead of working on pixels, the present study has a focus on clustering baselines/text lines into text blocks. Therefore, we introduce a new measure based on a baseline detection evaluation scheme. But also common pixel-based approaches could participate without restrictions. Working on baseline level addresses directly the application scenario where for a given image the contained text should be extracted in blocks for further investigations. We present the results of three submissions. The experiments have shown that text blocks can be reliably detected both on pages with a simple layout and on pages with a complex layout.

description: We develop a simple description of models where electroweak symmetry breaking is triggered by a light composite Higgs, which emerges from a strongly-interacting sector as a pseudo-Goldstone boson. Two parameters broadly characterize these models: m_rho, the mass scale of the new resonances and g_rho, their coupling. An effective low-energy Lagrangian approach proves to be useful for LHC and ILC phenomenology below the scale m_rho. We identify two classes of operators: those that are genuinely sensitive to the new strong force and those that are sensitive to the spectrum of the resonances only. Phenomenological prospects for the LHC and the ILC include the study of high-energy longitudinal vector boson scattering, strong double-Higgs production and anomalous Higgs couplings. We finally discuss the possibility that the top quark could also be a composite object of the strong sector.

description: Background: Few valid, disease‐specific measures of health‐related quality of life (HRQOL) capture the spectrum of symptoms associated with Huntington's disease (HD). The HD‐PRO‐TRIAD™ is a new, HD‐specific, patient‐reported outcome (PRO) instrument of the HD symptom triad (cognitive decline, emotional/behavioral dyscontrol, and motor dysfunction) designed for clinical research and practice. The objective was to validate the HD‐PRO‐TRIAD™ through a cross‐sectional sample of individuals with HD and caregivers. Methods: Development of the HD‐PRO‐TRIAD™ has been described elsewhere. A total of 132 individuals with HD and 40 HD caregivers, comprising 29 dyads, participated in the cross‐sectional psychometric validation of this instrument. Participants provided responses to the HD‐PRO‐TRIAD™ and other HRQOL and disease severity instruments (EuroQOL 5D, Short Form 12, Neuro‐QOL Item Banks, PROMIS Global Health, and self‐reported Unified Huntington's Disease Rating Scale Total Functional Capacity and Independence Scales). Internal consistency, construct validity, and patient–caregiver proxy consistency were evaluated. Results: Internal consistency of the three domains and overall HD‐PRO‐TRIAD™ instrument was supported by Cronbach's alpha values ≥0.94. Construct validity was supported by significant correlations between HD‐PRO‐TRIAD™ domain scores and other measures of the same domains (e.g., significant positive correlations between HD‐PRO‐TRIAD™ Anxiety with Neuro‐QOL Anxiety), as well as slightly weaker but still strong correlations with other HRQOL instruments (e.g., HD‐PRO‐TRIAD™ Anxiety and UHDRS Independence; all p<0.01). Consistency between patient self‐report and caregiver proxy report was supported by an intra‐class correlation coefficient ≥0.92 for all three domains and the overall instrument. Discussion: These data indicate that HD‐PRO‐TRIAD™ is a reliable and valid HRQOL instrument that captures the typical triad of HD symptoms.

description: We systematically analyze total reaction cross sections of carbon isotopes with N=6--16 on a $^{12}$C target for wide range of incident energy. The intrinsic structure of the carbon isotope is described by a Slater determinant generated from a phenomenological mean-field potential, which reasonably well reproduces the ground state properties for most of the even $N$ isotopes. We need separate studies not only for odd nuclei but also for $^{16}$C and $^{22}$C. The density of the carbon isotope is constructed by eliminating the effect of the center of mass motion. For the calculations of the cross sections, we take two schemes: one is the Glauber approximation, and the other is the eikonal model using a global optical potential. We find that both of the schemes successfully reproduce low and high incident energy data on the cross sections of $^{12}$C, $^{13}$C and $^{16}$C on $^{12}$C. The calculated reaction cross sections of $^{15}$C are found to be considerably smaller than the empirical values observed at low energy. We find a consistent parameterization of the nucleon-nucleon scattering amplitude, differently from previous ones. Finally, we predict the total reaction cross section of $^{22}$C on $^{12}$C.

Cotton duck canvas and the gray flannel suit : the material dialectics of American formalism
Creators: name: Steiner, Shep
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is concerned with art and culture in America from 1948 to 1955, primarily a period bound shift in the aesthetic practice of modernism which would result in the stain painting of Morris Louis. The purpose of this thesis is to trace the shift in cultural values which would promote the emergence and development of this new paradigm, that is to link a wider social and cultural progenesis of change to its formal articulation upon a highly aestheticized abstract canvas. Clement Greenberg's position in these negotiations is crucial. For him, the formal qualities of stain painting resonated and were linked to the larger cultural field of a vital and prospering new order. Intense color, "openness", and their implication of anonymity, united to become the signification of a particular kind of potential, translated as optimism, which he felt the moment possessed. This investigation will focus on the formal properties of stain painting as the elements of a project closely related to the politics of Greenberg himself; that indeed a generative stylistics for stain painting, specifically Louis' 1954 "Veil" series, is coupled to a distinct political culture at that time being elaborated. The historically specific framework of this thesis attempts to reconcile some of the inconsistencies in the reception of stain painting -- its lack thereof in the early 1950s, and its ultimate acceptance and critical acclaim by the 1960s. This thesis contends that the formal qualities of stain painting were a vection for the politics of a core group of Cold War intellectuals involved in an affirmative project for capitalism. That is any meaning — and hence too wider success — impersonality might have had, gained resonance only as the politics of this core of intellectuals themselves gained in power. To investigate these issues this study probes the complexities and the key position in the debate on popular culture. In an America of heightened consummerism and Cold War tensions what emerges as crucial is a reconception of the individual, of avant garde practice and of modernity itself.

description: An analysis of continuum antenna temperatures observed in the Green Bank Telescope (GBT) spectrometer bandpasses is presented for observations toward SgrB2(N-LMH). Since 2004, we have identified four new prebiotic molecules toward this source by means of rotational transitions between low energy levels; concurrently, we have observed significant continuum in the GBT spectrometer bandpasses centered at 85 different frequencies in the range of 1 to 48 GHz. The continuum heavily influences the molecular spectral features since we have observed far more absorption lines than emission lines for each of these new molecular species. Hence, it is important to understand the nature, distribution, and intensity of the underlying continuum in the GBT bandpasses for the purposes of radiative transfer, i.e. the means by which reliable molecular abundances are estimated. We find that the GBT spectrometer bandpass continuum is consistent with optically-thin, non thermal (synchrotron) emission with a flux density spectral index of -0.7 and a Gaussian source size of ~143" at 1 GHz that decreases with increasing frequency as nu^(-0.52). Some support for this model is provided by high frequency Very Large Array (VLA) observations of SgrB2.

description: Background: Hemimasticatory Spasm is a very rare disorder. Case report: A 62-year-old woman consulted with 30 years of unusual involuntary twitches in preauricular region and spasms that hamper jaw opening. During the spasms she cannot open her mouth for several seconds. At physical examination we observed hypertrophy of the masseter and temporalis muscles, shared features with Hemimasticatory Spasm. She was treated with botulinum toxin type A with excellent response. Discussion: Hemimasticatory Spasm is a rare movement disorder, but given the excellent response to botulinum toxin type A treatment, it should be considered in the spectrum of facial spasms.

Cosmological particle production in quantum gravity

description: Quantum theory of a test field on a quantum cosmological spacetime may be viewed as a theory of the test field on an emergent classical background. In such a case, the resulting dressed metric for the field propagation is a function of the quantum fluctuations of the original geometry. When the backreaction is negligible, massive modes can experience an anisotropic Bianchi type I background. The field modes propagating on such a quantum-gravity-induced spacetime can then unveil interesting phenomenological consequences of the super-Planckian scales, such as gravitational particle production. The aim of this paper is to address the issue of gravitational particle production associated to the massive modes in such an anisotropic dressed spacetime. By imposing a suitable adiabatic condition on the vacuum state and computing the energy density of the created particles, the significance of the particle production on the dynamics of the universe in Planck era is discussed.

description: Αντικείμενο της διδακτορικής διατριβής αποτελεί η συμβολή του μεταβολικού παράγοντα τριμεταζιδίνη(ΤΡΜ) στη μείωση της μυοκαρδιακής νέκρωσης που προκαλείται κατά τη διάρκεια αορτοστεφανιαίας παράκαμψης και αγγειοπλαστικής καθώς και στην πρόγνωση των ασθενών αυτών σε χρονικό ορίζοντα τριών μηνών. Μελετήθηκαν 100 ασθενείς, 51 ασθενείς που υποβλήθηκαν σε αγγειοπλαστική(27 ασθενείς έλαβαν ΤΡΜ ενώ 24 ασθενείς αποτέλεσαν την ομάδα ελέγχου) και 49 ασθενείς με αορτοστεφανιαία παράκαμψη(23 ασθενείς έλαβαν ΤΡΜ ενώ 26 ασθενείς ήταν η ομάδα ελέγχου). Οι ασθενείς έλαβαν ΤΡΜ 20mgr τρεις φορές ημερησίως για 15 τουλάχιστον ημέρες προ της επέμβασης επαναιμάτωσης και για 3 μήνες μετά. Στο σύνολο των ασθενών λήφθηκε λεπτομερές ιστορικό. Η έκταση της προκαλούμενης μυοκαρδιακής νέκρωσης εκτιμήθηκε με την καταγραφή των επιπέδων τροπονίνης Ι και Cu-MB προ της επέμβασης, 6ωρες, 24 και 48 ώρες μετά. Κάθε ασθενής υποβλήθηκε σε υπερηχογραφικό έλεγχο, πριν καθώς και έναν και 3 μήνες μετά. Η χορήγηση ΤΡΜ είχε ως αποτέλεσμα τη μείωση της προκαλούμενης μυοκαρδιακής νέκρωσης και τη βελτίωση της συνολικής (κλάσμα εξώθησης) και περιοχικής συσταλτικότητας της αριστερής κοιλίας, όμως δεν είχε θετική επίδραση στην πρόγνωση
description: The aim of this study is to evaluate whether. The administration of trimetazidine(TRM) in patients before and after revascularization procedures minimizes PCI/CABG induced myocardial damage. Hundred patients were included in this study; 51 patients who underwent PCI(27 patients received TRM while 24 patients did not) and 49 patients who underwent CABG(23 patients received TRM) while 26 patients did not). Patients received 20mg TRM orally every 8hours, started 15 days before revascularization and continued 3 months afterwards. A detailed history was taken from each patient. Serum troponine I and CU-MB levels were measured before, 6hours, 24 and 48hours after in order to detect the size of myocardial damage caused. 2D cardiac echo was performed in each patient before, one and 3 months after revascularization. Statistical analysis showed that TRM administration minimizes myocardial damage caused ADL improves Grobal(EF) and regional wall motion of LV, but don't affect patients' prognosis

description: Using the solitonic solution-generating technique we rederived the one-rotational five-dimensional black ring solution found by Emparan and Reall. The seed solution is not the Minkowski metric, which is the seed of $S^2$-rotating black ring. The obtained solution has more parameters than the Emparan and Reall's $S^1$-rotating black ring. We found the conditions of parameters to reduce the solution to the $S^1$-rotating black ring. In addition we examined the relation between the expressions of the metric in the prolate-spheroidal coordinates and in the canonical coordinates.

description: Background: For unclear reasons, many Tourette syndrome (TS) children report near‐complete tic remission by young adulthood. Immature maturation of brain networks, observed with resting‐state functional MRI (rs‐fc‐MRI) in adolescents and adults with TS, might evolve to a mature pattern in adults who experience tic improvement or remission. We explored the feasibility of testing this hypothesis in our population of young adult TS males, each with prior clinical assessments completed during childhood as part of a separate TS Association Genetics Consortium study. Methods: A total of 10 TS males (off tic suppressing drugs for at least 6 months) aged 19–32 years, mean follow‐up interval 7.5 (2 to 13) years, and 11 neurologically normal controls were enrolled and underwent 3‐Tesla structural and rs‐fc‐MRI sequences. Results: The mean change in Yale Global Tic Severity Scale (YGTSS) was −31.5% (total) and −26.6% (YGTSS motor+vocal). Two subjects reported resolution of tic‐related disability, with drops from mean 45 to 16.5 (YGTSS‐total) and 25 to 11.5 (YGTSS motor+vocal.). Rs‐fc‐MRI revealed significantly increased connectivity between the ipsilateral anterior and mid cingulate cortex and striatum, increased connectivity between local connections, and decreased connectivity between more distant connections; representing an immature connectivity pattern. Discussion: Similar to previous reports, we found immature patterns of functional connectivity in adult TS subjects. Despite a lack of complete tic remission, two subjects exhibited dramatic drops in tic severity that correlated with tic‐related disability improvement. More work is needed to elucidate the mechanism of such dramatic improvement in TS.
