description: EZ Cnc, or EPIC 212182292, is a non-Blazhko RRab variable star located in the field of K2 Campaign 16. Its atmospheric parameters ($T_{\rm eff}$, $\log{g}$, [M/H]) and radial velocities are measured from the 55 high-quality LAMOST medium-resolution spectra. The fundamental frequency of pulsation is derived as $f=1.8323(17)$ d$^{-1}$ from the K2 light curves. The amplitude ratios $R_{21} = 0.5115(15), 0.490(8)$, $R_{31} = 0.3249(20), 0.279(7)$ and Fourier phase differences $φ_{21}=2.7550(20), 2.764(16)$, $φ_{31}=5.7194(25), 5.719(31)$ are determined from the Fourier decomposition of K2 light curve and LAMOST radial velocity curve, respectively. Through the constraints of the parameters, four optimal models are obtained in a time-dependent turbulent convection model survey for EPIC 212182292. The parameters of EPIC 212182292 are derived as $M=0.48\pm0.03$ M$_{\odot}$, $L = 42\pm2$ L$_{\odot}$, $T_{\rm eff}=6846\pm50$ K, $\log{g}=2.79\pm0.01$ dex, and $Z = 0.006\pm0.002$, respectively. The precisely determined parameters for RRab variable stars like EPIC 212180092 might help to better understand the period-luminosity relationship of RR Lyrae stars.

description: We investigate the relationship between the nested organization of mutualistic systems and their robustness against the extinction of species. We establish that a nested pattern of contacts is the best possible one as far as robustness is concerned, but only when the least linked species have the greater probability of becoming extinct. We introduce a coefficient that provides a quantitative measure of the robustness of a mutualistic system.

Growth without capitalism : agrarian change in the peasant economy of Sri Lanka
Creators: name: Kumara, G. A. Kumudu Kusum
Publisher: name: University of British Columbia
Year: 2011

description: This study examines the impact of capital on the small peasant economy of Sri Lanka which has been dominated by paddy cultivation, the consequent processes of agrarian change in the peasant society and the impact of these changes on the lives of the peasantry. The persistence of peasant agriculture throughout the developing world has posed a challenge to classical theories of the development of capitalism in agriculture which considered peasant production or Simple Commodity Production as a transitional phenomenon doomed to disappear. Recent interpretations of theories on Simple Commodity Production however, argue that peasant forms of production can and likely will survive within capitalist social formations, and therefore the analysis of the dynamics of agrarian change has to focus on historically specific situations. Pursuing the latter view, this study identifies the role of the State, class structure, and the role of agro-ecological imperatives as key factors influencing agrarian change in Sri Lanka. While existing agrarian relations in the peasant sector have not become a barrier to the growth of productive forces in the peasant economy, this growth has not necessarily led to the disintegration of the peasantry, despite a certain amount of differentiation among them. While the dynamism manifested in the emergence of a small stratum of rich peasants and rural entrepreneurs may indicate the possibility of capitalist development in the peasant sector in some areas of the country, the overall situation within the peasant economy indicates the possibility of paddy agriculture reaching its advanced stages within the form of peasant production itself. In the event of such a possibility, it is the problem of underemployed labour in the peasant sector which will become the agrarian question of Sri Lanka.

description: Background: Patients with essential tremor (ET) have an increased prevalence of hearing loss, and depression is a confounding issue for both conditions. We assessed hearing loss in non‐depressed ET patients and controls using a questionnaire and audiometric tests. Methods: The study included 34 patients with ET and 45 volunteers were included. Both groups were asked if they had hearing loss, and pure tone audiometry, speech recognition threshold, tympanogram, short increment sensitivity index (SISI), tone decay, and otoacoustic emission audiological tests were conducted. Results: Seventeen subjects (50.0%) in the patient group answered “yes” to the question “Do you have hearing loss?” compared to one (2.2%) subject in the control group (p<0.001). The tone decay values of the right ear at 4,000 Hz were higher in the patient group. The number of subjects in which the otoacoustic emissions could not be obtained in the right ear was higher in the ET patients (p = 0.005). Discussion: The results support the presence of a cochlear pathology in ET and may indicate that ET and sensorineural hearing loss may be components of a common disease process.

description: We generalize the scattering theory of quantum shot noise to include the full spin-density matrix of electrons injected from a spin-filtering or ferromagnetic electrode into a quantum-coherent nanostructure governed by various spin-dependent interactions. This formalism yields the spin-resolved shot noise power for different experimental measurement setups--with ferromagnetic source and ferromagnetic or normal drain electrodes--whose evaluation for the diffusive multichannel quantum wires with the Rashba (SO) spin-orbit coupling shows how spin decoherence and dephasing lead to substantial enhancement of charge current fluctuations (characterized by Fano factors $> 1/3$). However, these processes and the corresponding shot noise increase are suppressed in narrow wires, so that charge transport experiments measuring the Fano factor $F_{\uparrow \to \uparrow \downarrow}$ in a ferromagnet/SO-coupled-wire/paramagnet setup also quantify the degree of phase-coherence of transported spin--we predict a one-to-one correspondence between the magnitude of the spin polarization vector and $F_{\uparrow \to \uparrow \downarrow}$.

Year: 2015

description: Background: Psychogenic or functional movement disorders (PMDs) pose a challenge in clinical diagnosis. There are several clues, including sudden onset, incongruous symptoms, distractibility, suggestibility, entrainment of symptoms, and lack of response to otherwise effective pharmacological therapies, that help identify the most common psychogenic movements such as tremor, dystonia, and myoclonus. Methods: In this manuscript, we review the frequency, distinct clinical features, functional imaging, and neurophysiological tests that can help in the diagnosis of uncommon presentations of PMDs, such as psychogenic parkinsonism, tics, and chorea; facial, palatal, and ocular movements are also reviewed. In addition, we discuss PMDs at the extremes of age and mass psychogenic illness. Results: Psychogenic parkinsonism (PP) is observed in less than 10% of the case series about PMDs, with a female–male ratio of roughly 1:1. Lack of amplitude decrement in repetitive movements and of cogwheel rigidity help to differentiate PP from true parkinsonism. Dopamine transporter imaging with photon emission tomography can also help in the diagnostic process. Psychogenic movements resembling tics are reported in about 5% of PMD patients. Lack of transient suppressibility of abnormal movements helps to differentiate them from organic tics. Psychogenic facial movements can present with hemifacial spasm, blepharospasm, and other movements. Some patients with essential palatal tremor have been shown to be psychogenic. Convergence ocular spasm has demonstrated a high specificity for psychogenic movements. PMDs can also present in the context of mass psychogenic illness or at the extremes of age. Discussion: Clinical features and ancillary studies are helpful in the diagnosis of patients with uncommon presentations of psychogenic movement disorders.

description: Surface termination is known to play an important role in determining the physical properties of materials. It is crucial to know how surface termination affects the metal-insulator transition (MIT) of V$_2$O$_3$ films for both fundamental understanding and its applications. By changing growth parameters, we achieved a variety of surface terminations in V$_2$O$_3$ films that are characterized by low energy electron diffraction (LEED) and photoemission spectroscopy techniques. Depending upon the terminations, our results show MIT can be partially or fully suppressed near the surface region due to the different filling of the electrons at the surface and sub-surface layers and change of screening length compared to the bulk. Across MIT, a strong redistribution of spectral weight and its transfer from high-to-low binding energy regime is observed in a wide-energy-scale. Our results show total spectral weight in the low-energy regime is not conserved across MIT, indicating a breakdown of `sum rules of spectral weight', a signature of a strongly correlated system. Such change in spectral weight is possibly linked to the change in hybridization, lattice volume ({\it i.e.,} effective carrier density), and spin degree of freedom in the system that happens across MIT. We find that MIT in this system is strongly correlation-driven where the electron-electron interactions play a pivotal role. Moreover, our results provide a better insight in understanding the electronic structure of strongly correlated systems and highlight the importance of accounting surface effects during interpretation of the physical property data mainly using surface sensitive probes, such as surface resistivity.

Year: 2015

description: Background: The sensory trick or geste antagoniste is a cardinal feature of cervical dystonia. Patients are often aware of their tricks, using them to their advantage to temporarily improve dystonic symptoms. The typical sensory trick must be internally generated by the patient in order to be effective, and external mechanical pressure alone may not be sufficient. Methods: We present a case description. We present and demonstrate a new clinical phenomenon in patients with cervical dystonia, which we call "closing the loop". Discussion: We discuss the possible mechanisms underlying this finding.

description: Considering the scale dependent effective spacetimes implied by the functional renormalization group in d-dimensional Quantum Einstein Gravity, we discuss the representation of entire evolution histories by means of a single, (d + 1)-dimensional manifold furnished with a fixed (pseudo-) Riemannian structure. This "scale-space-time" carries a natural foliation whose leaves are the ordinary spacetimes seen at a given resolution. We propose a universal form of the higher dimensional metric and discuss its properties. We show that, under precise conditions, this metric is always Ricci flat and admits a homothetic Killing vector field; if the evolving spacetimes are maximally symmetric, their (d + 1)-dimensional representative has a vanishing Riemann tensor even. The non-degeneracy of the higher dimensional metric which "geometrizes" a given RG trajectory is linked to a monotonicity requirement for the running of the cosmological constant, which we test in the case of Asymptotic Safety.

description: High degree of preservation of spin states during energy relaxation processes mediated by optical phonons is demonstrated in a single quantum dot. Optical-phonon resonance and relevant suppression of spin relaxation are clearly identified as dip structures in photoluminescence excitation spectra probed by the positive trion emission. The absence of continuum states makes this observation possible under the cross-circularly polarized detection with respect to a circularly polarized pumping. Consequently, distinguishably high degree of circular polarization up to ~0.85 is achieved without applying external magnetic field at the optical-phonon resonance. Rate equation analysis reveals that the spin-flip probability during energy relaxation is restricted to less than 7.5%. It is also indicated that the spin flip time of the positive trion ground state is extended by more than 3 times compared with that of neutral exciton ground state. This corresponds to the spin flip time longer than 11 ns for the positive trion ground state. The influence of nuclear polarization to the present measurements is also discussed.

description: Background: Blepharospasm is a focal cranial dystonia, which could be idiopathic in origin or secondary to an underlying disorder that commonly impairs quality of life. Botulinum toxin (BoNT) injections have become the treatment of choice; however, a less favorable response to BoNT is expected in secondary blepharospasm. No studies have been conducted comparing outcomes between blepharospasm cohorts. We therefore aim to compare BoNT outcomes in primary and secondary blepharospasm subjects. Methods: A retrospective review of 64 blepharospasm subjects receiving BoNT therapy was conducted. Demographics, BoNT treatment schedules, duration of BoNT therapy, and side effects were recorded. Outcome measures were duration of benefit, peak‐dose benefit recorded with the Clinical Global Impressions Scale (CGIS), and related side effects. Results: No difference was found between the two cohorts regarding duration of benefit from treatment (primary 9.47 weeks vs. secondary 9.63 weeks, p = 0.88). Perceived peak‐dose benefit was more commonly reported as “very much improved” in secondary patients, but this was not significant (p = 0.13). Higher BoNT dosages were required in both groups over time, with a mean increase of 20.5% in primary and 26.5% in secondary blepharospasm. Ptosis (8%) and diplopia (6%) were the most common reported side effects. Mean follow‐up in years was similar between groups, 3.6 years for primary vs. 2.4 years for secondary blepharospasm (p = 0.17). Discussion: BoNT injections were effective with comparable benefits seen in both primary and secondary blepharospasm populations. Clinicians should be aware of the similar benefit from BoNT reported in secondary blepharospasm patients. The average duration of benefit in this cohort was comparable with previous reports.

The Impact of Sampling and Rule Set Size on Generated Fuzzy Inference System Predictive Accuracy: Analysis of a Software Engineering Data Set

description: Software project management makes extensive use of predictive modeling to estimate product size, defect proneness and development effort. Although uncertainty is acknowledged in these tasks, fuzzy inference systems, designed to cope well with uncertainty, have received only limited attention in the software engineering domain. In this study we empirically investigate the impact of two choices on the predictive accuracy of generated fuzzy inference systems when applied to a software engineering data set: sampling of observations for training and testing; and the size of the rule set generated using fuzzy c-means clustering. Over ten samples we found no consistent pattern of predictive performance given certain rule set size. We did find, however, that a rule set compiled from multiple samples generally resulted in more accurate predictions than single sample rule sets. More generally, the results provide further evidence of the sensitivity of empirical analysis outcomes to specific model-building decisions.

description: Background: While current research suggests that genetic factors confer the greatest risk for the development of tic disorders, studies of environmental factors are relatively few, with a lack of consistent risk factors across studies. Our aim is to analyze the association of tic disorders with exposure to prenatal and perinatal morbidity. Methods: This was a nested case–control study design. Cases and controls were selected and identified from a mainstream, school-based sample. The diagnosis of tic disorders was assigned by a movement disorder neurologist using ‘Diagnostic and statistical manual of mental disorders, 4th edition, text revision’ criteria, and neuropsychiatric comorbidities were screened using the Spanish computerized version of the Diagnostic Interview Schedule for Children Predictive Scale. Information regarding the exposure to pre-perinatal risk factors was collected by a retrospective review of the birth certificates. Logistic regression analyses were then performed to test the association of tic disorders with pre-perinatal risk factors. Results: Out of 407 participants, complete pre-perinatal data were available in 153 children (64 with tics and 89 without tics);. After adjusting for family history of tics, neonatal respiratory distress syndrome, body mass index, prenatal infection, and coexisting comorbid neuropsychiatric disturbances, tic disorders were associated with prenatal exposure to tobacco (odds ratio [OR] = 3.07, 95% confidence interval [CI] 1.24–7.60, p = 0.007), and cesarean section (OR = 5.78, 95% CI 1.60–20.91, p = 0.01). Discussion: This nested case–control study of children with tic disorders demonstrates higher adjusted odds for tics in children with exposure to cesarean delivery and maternal smoking. Longitudinal, population-based samples are required to confirm these results.

description: Background: Alien hand syndrome (AHS) is a disorder of involuntary, yet purposeful, hand movements that may be accompanied by agnosia, aphasia, weakness, or sensory loss. We herein review the most reported cases, current understanding of the pathophysiology, and treatments. Methods: We performed a PubMed search in July of 2014 using the phrases “alien hand syndrome,” “alien hand syndrome pathophysiology,” “alien hand syndrome treatment,” and “anarchic hand syndrome.” The search yielded 141 papers (reviews, case reports, case series, and clinical studies), of which we reviewed 109. Non‐English reports without English abstracts were excluded. Results: Accumulating evidence indicates that there are three AHS variants: frontal, callosal, and posterior. Patients may demonstrate symptoms of multiple types; there is a lack of correlation between phenomenology and neuroimaging findings. Most pathologic and functional imaging studies suggest network disruption causing loss of inhibition as the likely cause. Successful interventions include botulinum toxin injections, clonazepam, visuospatial coaching techniques, distracting the affected hand, and cognitive behavioral therapy. Discussion: The available literature suggests that overlap between AHS subtypes is common. The evidence for effective treatments remains anecdotal, and, given the rarity of AHS, the possibility of performing randomized, placebo‐controlled trials seems unlikely. As with many other interventions for movement disorders, identifying the specific functional impairments caused by AHS may provide the best guidance towards individualized supportive care.

description: We present a detailed description of the experiment realising for the first time a protective measurement, a novel measurement protocol which combines weak interactions with a ``protection mechanism'' preserving the measured state coherence during the whole measurement process. Furthermore, protective measurement allows finding the expectation value of an observable, i.e. an inherently statistical quantity, by measuring a single particle, without the need of any statistics. This peculiar property, in sharp contrast with the framework of traditional (projective) quantum measurement, might constitute a groundbreaking advance for several quantum technology related fields.

description: The notion of hypothetical bias (HB) constitutes, arguably, the most fundamental issue in relation to the use of hypothetical survey methods. Whether or to what extent choices of survey participants and subsequent inferred estimates translate to real-world settings continues to be debated. While HB has been extensively studied in the broader context of contingent valuation, it is much less understood in relation to choice experiments (CE). This paper reviews the empirical evidence for HB in CE in various fields of applied economics and presents an integrative framework for how HB relates to external validity. Results suggest mixed evidence on the prevalence, extent and direction of HB as well as considerable context and measurement dependency. While HB is found to be an undeniable issue when conducting CEs, the empirical evidence on HB does not render CEs unable to represent real-world preferences. While health-related choice experiments often find negligible degrees of HB, experiments in consumer behaviour and transport domains suggest that significant degrees of HB are ubiquitous. Assessments of bias in environmental valuation studies provide mixed evidence. Also, across these disciplines many studies display HB in their total willingness to pay estimates and opt-in rates but not in their hypothetical marginal rates of substitution (subject to scale correction). Further, recent findings in psychology and brain imaging studies suggest neurocognitive mechanisms underlying HB that may explain some of the discrepancies and unexpected findings in the mainstream CE literature. The review also observes how the variety of operational definitions of HB prohibits consistent measurement of HB in CE. The paper further identifies major sources of HB and possible moderating factors. Finally, it explains how HB represents one component of the wider concept of external validity.

Nous n'avons pas trouve beaucoup de icones a honore d'Eustathe(seulement une miniature et quelques autres). Nous avons examine sa fete dans les Synaxaires, les Typiques, etc. de l'Eglise orthodoxie, depuis le 9e siecle. En examinant la vie d'Eustathie d'Antioche nous avons fait beuacoup des propositions aux sujets ou les savants ne sont pas d'accord. De plus nous avons donne des solutions en utilisant le Droit Canon. Nous avons presente les ouvrages et l'ensiegnement dogmatique du Pere, avec beaucoup des elements nouveaux
description: In this Doctorate, we have presented, for the first time, approximately 150 Hymns of the Church which are dedicated to saint Eustathius of Antioche, from 14 manuscripts inedits(Mount Athos, National Library of the Greece, patriarchate of Alaxadria, Mount Sinai, Library of Oxford, Library of Marciani), from 12th to 15th century. We have also presented a Liturgy, which is concidered to have been written by saint Eustathius, from a manuscript Syriac(13 century). Additionally, we have include in our work some icons of the Saint, and we have compare them with a description of his characteristics ohysiognostical in a text of the 13 century and we have proved that there is less resemblance between the description in it and the icans. As far as saint Eustathius's life is concerning, we have examined thoroughly every step of it and as we have given logical explanation of his life is that we tried to find solutions on equivocal issues, with the utilization of the "Droit Canon" by which it was easy enough to come to specific results. Despite of the proficiency on the examination of saint Eustathius's book and his Theology, we tried to approach these subjects from an other point of view and we have presented very intersting inferences, specifically on issues which have been set for the first time

description: Στη διατριβή αυτή μελετάται το δισδιάστατο ανάλογο του κώδικα. Για το λόγο αυτό, εισάγεται το δισδιάστατο διπλοβαθμωτό μονοειδές που αντιστοιχεί στο μονοειδές λέξεων. Αποδεικνύεται ότι μια γλώσσα εικόνων C είναι κώδικας ακριβώς όταν το παραγόμενο διπλοβαθμωτό μονοειδές Co είναι ελεύθερο, δηλ. αν και μόνο αν το Co είναι οριζόντια, κατακόρυφα και κυκλικά ευσταθές. Eπιπλέον εδραιώνεται μια ασθενής εκδοχή εικονοκωδίκων, τα ΒΔ προθεματικά σύνολα, η οποία αποτελεί η γενίκευση των προθεματικών συνόλων λέξεων. Στο τελευταίο εισάγεται η έννοια της τετραπολικής σχέσης απαραίτητης για τον ορισμό του τετραπολικού αυτομάτου, το οποίο αναγνωρίζει δισδιάστατες γλώσσες. Ορίζονται σειρές εικόνων και τετραπολικά αυτόματα με βάρη, των οποίων οι συμπεριφορές είναι εικονοσειρές. Τέλος, δίνεται ένας χαρακτηρισμός των εικονοκωδίκων με τη βοήθεια των εικονοσειρών
description: In this thesis the two-dimensional analog of code is studied. For this reason, the two-dimensional doubly-ranked monoid is introduced which corresponds to the word monoid. It is proved that a picture language C is a code exactly when the generated doubly-ranked monoid C is free, i.e. if and only if C is horizontally, vertically and circularly stable. Moreover a weak version of the well-known defect theorem is established and a class of picture codes is defined, the NW-prefix sets, which constitutes the generalization of word prefix sets. In the last chapter the notion of quadrapolic relation is introduced, necessary for the definition of the quadrapolic automaton which recognizes two-dimensional languages. Pictures series and weighted quadrapolic automata are defined, whose behaviors are picture series. last but not least, a characterization of picture codes through picture series is given

description: In this paper, we formulate two new classes of black hole solutions in higher curvature quartic quasitopological gravity with nonabelian Yang-Mills theory. At first step, we consider the $SO(n)$ and $SO(n-1,1)$ semisimple gauge groups. We obtain the analytic quartic quasitopological Yang-Mills black hole solutions. Real solutions are only accessible for the positive value of the redefined quartic quasitopological gravity coefficient, $μ_{4}$. These solutions have a finite value and an essential singularity at the origin, $r=0$ for space dimension higher than $8$. We also probe the thermodynamic and critical behavior of the quasitopological Yang-Mills black hole. The obtained solutions may be thermally stable only in the canonical ensemble. They may also show a first order phase transition from a small to a large black hole. In the second step, we obtain the pure quasitopological Yang-Mills black hole solutions. For the positive cosmological constant and the space dimensions greater than eight, the pure quasitopological Yang-Mills solutions have the ability to produce both the asymptotically AdS and dS black holes for respectively the negative and positive constant curvatures, $k=-1$ and $k=+1$. This is unlike the quasitopological Yang-Mills theory which can lead to just the asymptotically dS solutions for $Λ>0$. The pure quasitopological Yang-Mills black hole is not thermally stable.

Noncooperative games of information sharing and investment : theories and applications
Creators: name: Kao, Jennifer L.
Publisher: name: University of British Columbia
Year: 2011

description: The thesis considers the effects of public policy with respect to disclosure on rivalrous competition in duopolies. Principal contributions to the stochastic oligopoly theories of information sharing include imbedding an investment stage in the standard noncooperative two-stage information sharing/output (pricing) games under a wide range of assumptions about effects of investment or distributions of returns, and investigating the extent to which altering the usual preference assumption to allow risk aversion may affect information choice. At an information sharing level, it is established that, besides being sensitive to the type of competition and the nature of information asymmetries, as previously reported in the literature, private incentives to disclose also depend importantly on both the impact of investment and risk preferences. In this regard, equilibrium levels of investment are shown to be affected nontrivially by variance effects from investment, risk attitude of decision makers, as well as the type of industry rivalry. Also characterized are the welfare orderings obtained as a consequence of these varying disclosure effects on the decisions and hence profits of competing firms. If alternative accounting practices are distinguishable along the informativeness dimension, then, at an abstract level, the analysis can be seen as approaching the study of many accounting issues from a distinctly different perspective than the familiar tax or wealth transfer viewpoints. The principal contributions to the accounting literature include identifying the impact of disclosure rules or rule changes on industry, consumers, and society as a whole, and offering insights to the accounting policy makers concerning the results of disclosure regulation.

description: A Langmuir film is a molecularly thin film on the surface of a fluid; we study the evolution of a Langmuir film with two co-existing fluid phases driven by an inter-phase line tension and damped by the viscous drag of the underlying subfluid. Experimentally, we study an 8CB Langmuir film via digitally-imaged Brewster Angle Microscopy (BAM) in a four-roll mill setup which applies a transient strain and images the response. When a compact domain is stretched by the imposed strain, it first assumes a bola shape with two tear-drop shaped reservoirs connected by a thin tether which then slowly relaxes to a circular domain which minimizes the interfacial energy of the system. We process the digital images of the experiment to extract the domain shapes. We then use one of these shapes as an initial condition for the numerical solution of a boundary-integral model of the underlying hydrodynamics and compare the subsequent images of the experiment to the numerical simulation. The numerical evolutions first verify that our hydrodynamical model can reproduce the observed dynamics. They also allow us to deduce the magnitude of the line tension in the system, often to within 1%. We find line tensions in the range of 200-600 pN; we hypothesize that this variation is due to differences in the layer depths of the 8CB fluid phases.

description: The cool white dwarf WD 1856+534 was found to be transited by a Jupiter-sized object with a mass at or below 14 M$_{\rm{Jup}}$. We used the GTC telescope to obtain and analyse photometry and low resolution spectroscopy of six transits of WD 1856+534 b, with the intention to derive the slope of the transmission spectrum, towards an eventual detection of Rayleigh scattering of the particles in its atmosphere. Such a slope, assuming a cloud-free atmosphere dominated by Rayleigh scattering, could be translated into an estimation of the mass of WD 1856+534 b. However, the resultant transmission spectrum is essentially flat, and therefore permits only the determination of lower mass limits of 2.4 M$_{\rm{Jup}}$ at the 2-$σ$ level, or 1.6 M$_{\rm{Jup}}$ at 3-$σ$. These limits have implications for some of the proposed formation scenarios for the object. We elaborate on the potential effects of clouds and hazes in our estimations, based on previous studies of Jupiter and Titan. In addition, we detected an H$α$ absorption feature in the combined spectrum of the host white dwarf, that leads to the assignation of a DA classification and allows derivation of an independent set of atmospheric parameters. Furthermore, the epochs of five transits were measured with sub-second precision, which demonstrates that additional objects more massive than $\approx$5 M$_{\rm{Jup}}$ and with periods longer than $O(100)$ days could be detected through the light travel time effect

description: Cet article propose un modèle de type GARCH (Generalized Autoregressive Conditional Heteroskedasticity) pour bien prévoir la Valeur-à-Risque quotidienne du marché boursier marocain. Cette approche, dite paramétrique, excelle dans la prévision de la Valeur-à-Risque grâce à sa capacité à modéliser la volatilité dynamique des rendements sur le marché. Elle capte ainsi la nature changeante de la volatilité au fil du temps et s'ajuste de manière plus sensible aux chocs soudains.

description: Background: Tetrabenazine is a monoamine depleter with a well-documented effect against chorea associated with Huntington disease (HD). There is a paucity of data about how reduction in chorea relates to better performance on motor, gait, cognitive, and psychiatric assessments. Methods: We designed an open label tetrabenazine withdrawal study to test performance using validated scales. The following instruments were used to assess cognitive, behavioral, and motor function in 10 patients with documented HD: The Montreal Cognitive Assessment, Beck Depression Inventory II, Dynamic Gait Index (DGI), Jebsen Hand Test, Timed 25-foot walk, Berg Balance Test (BBT), QuickDASH, and the Unified Huntington Disease Rating Scale (UHDRS) Motor, Stroop Color Word, Behavioral Assessment, Functional Checklist, and Independence Scale. Results: Subjects performed significantly better while on tetrabenazine as measured by the DGI (p = 0.041), BBT (p = 0.007), and the UHDRS Total Motor (p = 0.009), Maximum Chorea (p = 0.005), and Stroop Color-Word tests (p = 0.028). Discussion: This pilot study demonstrates tetrabenazine's potential effects beyond improvement in chorea.

description: We present the discovery of 24 pulsars in 15 Globular Clusters (GCs) using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). These include the first pulsar discoveries in M2, M10, and M14. Most of the new systems are either confirmed or likely members of binary systems. M53C, NGC6517H and I are the only three pulsars confirmed to be isolated. M14A is a black widow pulsar with an orbital period of 5.5 hours and a minimum companion mass of 0.016 \Ms. M14E is an eclipsing binary pulsar with an orbital period of 20.3 hours. With the other 8 discoveries that have been reported elsewhere, in total 32 GC pulsars have been discovered by FAST so far. In addition, We detected M3A twice. This was enough to determine that it is a black widow pulsar with an orbital period of 3.3 hours and a minimum companion mass of 0.0125 \Ms.
