description: We apply the Hybrid-Multi-Determinant method using the recent chiral two-body interactions of Entem-Machleidt-Nosyk (EMN) without renormalization to few nuclei up to A=48. Mostly we use the bare fifth order NN interaction N4LO-450. For ${}^{24}Mg$ and ${}^{48}Cr$ the excitation energies of the $2^+_1$ states are far larger than the corresponding experimental values.

description: Background: Hereditary spastic paraplegias (HSPs) are a clinically and genetically heterogeneous group of neurological diseases, which typically present with progressive lower extremity weakness and spasticity causing progressive walking difficulties. Complicating neurological or extraneurological features may be present. Case Report: We describe a 19-year-old male who was referred because of an action tremor of the hands; he later developed walking difficulties. Callosal atrophy was present on his cerebral magnetic resonance imaging scan, prompting genetic testing for SPG11, which revealed homozygous mutations. Discussion: The clinical features, differential diagnosis and management of SPG11, the most common form of autosomal recessive complicated HSP with a thin corpus callosum are discussed.

description: We study quantum information inequalities and show that the basic inequality between the quantum variance and the metric adjusted skew information generates all the multi-operator matrix inequalities or Robertson type determinant inequalities studied by a number of authors. We introduce an order relation on the set of functions representing quantum Fisher information that renders the set into a lattice with an involution. This order structure generates new inequalities for the metric adjusted skew informations. In particular, the Wigner-Yanase skew information is the maximal skew information with respect to this order structure in the set of Wigner-Yanase-Dyson skew informations. Key words and phrases: Quantum covariance, metric adjusted skew information, Robertson-type uncertainty principle, operator monotone function, Wigner-Yanase-Dyson skew information.

description: Background: Whereas structural abnormalities in the cerebellum have been associated with essential tremor (ET), the contribution of vascular disease via white matter hyperintensities (WMHs) and strokes has not been examined. In this study, we explored these potential associations and hypothesized that ET would be associated with greater overall WMH volume, greater cerebellar WMH volume and greater infarct presence. Methods: In a cross-sectional magnetic resonance imaging (MRI) study of 540 community-dwelling elderly persons in northern Manhattan, New York, brain measures of total WMH volume and regional WMH volume were derived from T2-weighted FLAIR-weighted MR images. Presence of cerebral infarcts on MRI was determined as well. Results: Total WMH volume was greater among 33 ET cases than 507 controls in both univariate (OR=1.41, p=0.038) and fully adjusted analyses (OR=1.44, p=0.03). Cerebellar WMH volume was associated with marginally increased odds of ET in a univariate model (OR=1.52, p=0.11) and significantly increased odds in a fully adjusted multivariate model (OR=1.74, p=0.049). Temporal lobe WMH volume was associated with significantly increased odds of ET in both univariate (OR=3.36, p<0.001) and fully adjusted models (OR=3.73, p<0.001). Large strokes were significantly more common in cases than controls in unadjusted analyses (OR=3.04, p=0.02) and marginally in adjusted analyses (OR=2.56 - 2.57, p=0.045 - 0.056). The distribution of strokes did not differ by diagnosis. Discussion: MRI data in this study indicated that ET was associated with greater total WMH volume, greater cerebellar WMH volume and possibly more strokes. Cerebrovascular disease could play a role in the development of ET.

Year: 2012

description: Background: Essential tremor (ET) is the most common tremor disorder. ET has classically been viewed as a benign monosymptomatic condition. Yet over the past 10 years, a growing body of evidence indicates that this is a progressive condition that is clinically heterogeneous, and may be associated with a variety of different features. Large epidemiological studies such as the Neurological Disorders of Central Spain (NEDICES), a longitudinal, population-based survey, have contributed significantly to the changing view of the disease. Our aim is to review some of the main results of NEDICES within the larger framework of the epidemiology of ET. Methods: Data for this review were gathered from all our articles published up to October 2011 regarding NEDICES study and “Essential Tremor”. Results: We have published 18 articles up to October 2011. The prevalence, incidence, and mortality of ET were analyzed in this cohort. In addition, ET was found to be associated with increased frailty and low morale, as well as with a series of non-motor manifestations, including cognitive deficits, mild cognitive impairment, dementia, depressive symptoms, and hearing impairment. Finally, the link between ET and Parkinson's disease (PD) was formally quantified in the NEDICES study, which demonstrated that the risk of developing incident PD was 4.3 times higher in prevalent ET cases than in age-matched controls without ET. Conclusions: This review highlights the contributions of NEDICES towards the advancement of current knowledge of the epidemiology and clinical features of ET, and emphasizes the importance of population-based studies towards the understanding of complex, ageing-related diseases.

description: In this work, we demonstrate a massive intrinsic exchange bias (3 kOe) in epitaxial CoFe2O4(111) thin films deposited on Al2O3(0001) substrates. This exchange bias is indicative of intrinsic exchange or a ferromagnetic material combined with an antiferromagnet. The analysis of structure, magnetism and electronic states corroborate that there is an interfacial layer CoO between the CoFe2O4(111) thin film and the Al2O3(0001) substrate. The power-law thickness dependence of the intrinsic exchange bias verifies its interfacial origin. This work suggests interfacial engineering can be an effective route for achieving large exchange bias.

description: The present thesis aims at studying the liquid - liquid membrane - based solvent extraction and consists of the understanding of the mass transfer mechanism, the process design and the development of criteria for the performance optimization upon the selection of the operating conditions. In order to study mass transfer in membrane modules, the following case is considered: parallel flow through a bundle of hollow fibers with simultaneous solute diffusion from an aqueous feed phase (flowing in the shell side) to an organic solvent (flowing in the fiber lumen). The study is focused on the shell side mass transfer and in particular on the effect of the fiber packing fraction, φ. For the class of problems considered here, i.e. liquid systems characterized by sufficiently large Schmidt numbers, Sc, a laminar flow boundary layer solution is obtained for the mass transfer rate to the outer fiber surface. To assess the aforementioned closed - form equation, two model flow fields are considered: flow along a single fiber, placed symmetrically in a tube (Model I) and flow along hypothetical annular elements or cells (each one surrounding a fiber) (Model II). According to this analysis (for the shell side), the Sherwood number, Shw, dependence on Reynolds number, Rew, and on fiber packing fraction, φ, is derived. By combining the closed - form equation for the shell side mass transfer with known expressions for the diffusion through the membrane pores as well as for the lumen side mass transfer, a predictive model is obtained for the solute concentrations at both exit streams (aqueous and organic phases), depending on several physico - chemical parameters
On the multiscale behaviour of stellar activity and rotation of the planet host Kepler-30

description: Kepler-30 is a unique target to study stellar activity and rotation in a young solar-like star accompanied by a compact planetary system. We use about 4 years of high-precision photometry collected by the Kepler mission to investigate the fluctuations caused by photospheric convection, stellar rotation, and starspot evolution as a function of the timescale. Our main goal is to apply methods for the analysis of timeseries to find the timescales of the phenomena that affect the light variations. We correlate those timescales with periodicities in the star as well as in the planetary system. We model the flux rotational modulation induced by active regions using spot modelling and apply the MFDMA in standard and multiscale versions for analysing the behaviour of variability and light fluctuations that can be associated with stellar convection and the evolution of magnetic fields on timescales ranging from less than 1 day up to about 35 days. The light fluctuations produced by stellar activity can be described by the multifractal Hurst index that provides a measure of their persistence. The spot modeling indicates a lower limit to the relative surface differential rotation of $ΔΩ/Ω\sim 0.02\pm 0.01$ and suggests a short-term cyclic variation in the starspot area with a period of $\sim 34$ days, virtually close to the synodic period of 35.2 days of the planet Kepler-30b. By subtracting the two timeseries of the SAP and PDC Kepler pipelines, we reduce the rotational modulation and find a 23.1-day period close to the synodic period of Kepler-30c. This period also appears in the multifractal analysis as a crossover of the fluctuation functions associated with the characteristic evolutionary timescales of the active regions in Kepler-30 as confirmed by spot modelling. These procedures and methods may be greatly useful for analysing current TESS and future PLATO data.

description: This thesis deals with the retrieval and mining of musical data in wired and wireless environments, which is stimulated by the need for increased efficiency in the retrieval as well as mining of non-obvious information from the previously mentioned musical data in a plethora of different systems that manage the continuously increasing volume of the musical data. In detail, the thesis focuses on the process of information from symbolic music data and the retrieval of acoustical music pieces. As far as the symbolic data concerned, the methods presented herein collect structural elements based on which new methods for the representation, as well as the genre classification of the musical information are derived. As for the bulky acoustic data, the thesis focuses on indexing for their faster retrieval and methods for their retrieval in wired and wireless peer-to-peer networks

description: Quantum error correcting codes protect quantum computation from errors caused by decoherence and other noise. Here we study the problem of designing logical operations for quantum error correcting codes. We present an automated procedure which generates logical operations given known encoding and correcting procedures. Our technique is to use variational circuits for learning both the logical gates and the physical operations implementing them. This procedure can be implemented on near-term quantum computers via quantum process tomography. It enables automatic discovery of logical gates from analytically designed error correcting codes and can be extended to error correcting codes found by numerical optimizations. We test the procedure by simulation on classical computers on small quantum codes of four qubits to fifteen qubits and show that it finds most logical gates known in the current literature. Additionally, it generates logical gates not found in the current literature for the [[5,1,2]] code, the [[6,3,2]] code, and the [[8,3,2]] code.

description: Background: Both hypothyroidism and Hashimoto's thyroiditis (HT) can rarely be associated with cerebellar ataxia. Severe essential tremor (ET) as well as bilateral thalamic deep brain stimulation (DBS) may lead to subtle cerebellar signs. Case Report: We report a 74-year-old male with hypothyroidism and a 20-year history of ET who developed cerebellar ataxia after bilateral thalamic DBS. Extensive workup revealed elevated thyroid stimulating hormone and thyroperoxidase antibody titers confirming the diagnosis of HT. Discussion: Our case demonstrates multiple possible causes of cerebellar ataxia in a patient, including hypothyroidism, HT, chronic ET, and bilateral thalamic DBS. Counseling of patients may be appropriate when multiple risk factors for cerebellar ataxia coexist in one individual.

description: This paper proposes a general enhancement to the Normalizing Flows (NF) used in neural vocoding. As a case study, we improve expressive speech vocoding with a revamped Parallel Wavenet (PW). Specifically, we propose to extend the affine transformation of PW to the more expressive invertible non-affine function. The greater expressiveness of the improved PW leads to better-perceived signal quality and naturalness in the waveform reconstruction and text-to-speech (TTS) tasks. We evaluate the model across different speaking styles on a multi-speaker, multi-lingual dataset. In the waveform reconstruction task, the proposed model closes the naturalness and signal quality gap from the original PW to recordings by $10\%$, and from other state-of-the-art neural vocoding systems by more than $60\%$. We also demonstrate improvements in objective metrics on the evaluation test set with L2 Spectral Distance and Cross-Entropy reduced by $3\%$ and $6\unicode{x2030}$ comparing to the affine PW. Furthermore, we extend the probability density distillation procedure proposed by the original PW paper, so that it works with any non-affine invertible and differentiable function.

The generalized partition functions, internal energies, free energies and temperature factor (or Debye-Waller factor) are calculated. It has also been observed that the temperature factor is dependent on the non-extensive parameter q which behaves like a scale parameter in the harmonic oscillator model. As $q\to 1$, we also show that these approximations agree with the result of Gaussian network model.

Blepharospasm with Anterocollis: A Distinctive Subphenotype of Segmental Craniocervical Dystonia
Creators: name: Waln, Olga
name: LeDoux, Mark S.
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2011

description: Background: Dystonia of the eyelids often spreads to affect other muscles in the craniocervical region. Certain blepharospasm-plus subphenotypes may be clinically unique. Methods: Seven subjects with the subphenotype of late-onset blepharospasm with apraxia of eyelid opening and anterocollis were identified from a database of over 1800 patients with primary dystonia. Results: Blepharospasm was the first affected site in 6/7 subjects followed by spread of the disease to the cervical muscles. Although 4 patients also had other forms of dystonia (laryngeal, lower face), none showed spread outside the craniocervical region. Family history of dystonia was present in 4/7. No mutations were identified in THAP1 or TOR1A. Overall, blepharospasm was difficult to treat, typically requiring both myectomy and substantial doses of botulinum toxin into the pretarsal orbicularis oculi muscles. In one subject, anterocollis markedly improved after deep brain stimulation. Discussion: Delineation and characterization of craniocervical dystonia subphenotypes may serve to guide genetic and therapeutic studies, in addition to clinical interventions. The blepharospasm with apraxia of eyelid opening and anterocollis subphenotype can be therapeutically challenging.

description: Evolving networks with a constant number of edges may be modelled using a rewiring process. These models are used to describe many real-world processes including the evolution of cultural artifacts such as family names, the evolution of gene variations, and the popularity of strategies in simple econophysics models such as the minority game. The model is closely related to Urn models used for glasses, quantum gravity and wealth distributions. The full mean field equation for the degree distribution is found and its exact solution and generating solution are given.

"Zuwachs unsrer existenz" : the quest for Being in J.M.R. Lenz
Creators: name: O'Regan, Inge Brigitta
Publisher: name: University of British Columbia
Year: 2011

description: Jakob Michael Reinhold Lenz (1751-1792), whose plays have been acclaimed as the prototype of the modern drama of Brecht and Durrenmatt, is a controversial figure who rose to prominence on the German literary scene in the early seventeen seventies. Among Lenz's theoretical writings is the influential essay "Anmerkungen ubers Theater," in which he introduces his innovative dramatic theories and describes the independent protagonists he envisions for the German stage. In the same essay, he demands "Zuwachs unsrer Existenz" (a heightened awareness of existence) from contemporary drama. However, in marked contrast to the "Anmerkungen," the protagonists of his two most prominent plays, Der Hofmeister (1774) and Die Soldaten (1776), are self-alienated, ontologically insecure individuals who seem victims of the socio-political realities of their times. Not surprisingly, critics are divided in their opinion as to what the contradictions in Lenz's oeuvre signify. Lenz was a student of Immanuel Kant's between 1768 and 1770, a time when the latter was formulating ideas that would find their full expression years later in his critical philosophy. In 1770, Kant presented his inaugural address "de mundi sensibilis atque intelligibilis forma et principiis" (On the Form and Principles of the Sensible and Intelligible World) to the assembled faculty and students of KCnigsberg Academy, among them J.M.R. Lenz. It is in the inaugural dissertation that Kant introduces his thesis of the individual as an inhabitant of two "worlds," the noumenal and the phenomenal, a central concept in his first critique, Kritik der reinen Vernunft, which would be published in 1781. This study examines Lenz's thoughts as they surface in his theoretical essays and his major plays and puts forward the thesis that it is Kant's division of the self into an intelligible and a sensible realm which prompts Lenz's call for "Zuwachs unsrer Existenz." Lenz's quest is fuelled, furthermore, by his acute awareness of the ontological insecurity of the individual self, an awareness which seems to anticipate the thought of Kierkegaard. The overriding purpose of this thesis is, through a reevaluation of Lenz's theoretical and dramatic works, to elucidate this eighteenth-century writer's quest for authentic being, a quest that he considered to be the individual's most urgent task.

description: Chiral monopoles are hedgehoglike structures in local chiral condensates in QCD. These monopoles are (i) made of quark and gluon fields; (ii) explicitly gauge-invariant; and (iii) they carry quantized and conserved chromomagnetic charge. We argue that the chiral condensate vanishes in a core of the chiral monopole while the density of these monopoles increases with temperature wiping out the quark condensate in quark-gluon plasma. We suggest that the dynamics of the chiral monopoles is responsible for the chiral symmetry restoration in high temperature phase of QCD. We also argue that the chiral monopoles are unlikely to be associated with confining degrees of freedom. In our approach the chiral symmetry restoration and the color deconfinement in QCD are not necessarily related to each other and the corresponding transitions may occur at different temperatures.

description: Background: Although voice tremor is one of the most commonly-noted clinical features of essential tremor (ET), there are nearly no published data on the handicap associated with it. Methods: The Voice Handicap Index (VHI) was self-administered by participants enrolled in a research study at Columbia-University Medical Center. The VHI quantifies patients' perceptions of handicap due to voice difficulties. Data from 98 ET cases were compared to data from 100 controls and 85 patients with another movement disorder (Parkinson’s disease, PD). Results: Voice tremor was present on examination in 25 (25.5%) ET cases; 12 had mild voice tremor (ETMild VT) and 13 had marked voice tremor (ETMarked VT). VHI scores were higher in ET cases than controls (p=0.02). VHI scores among ETMarked VT were similar to those of PD cases; both were significantly higher than controls (p<0.001). The three VHI subscale scores (physical, functional, emotional) were highest in ETMarked VT, with values that were similar to those observed in PD. Conclusions: The voice handicap associated with ET had multiple (i.e., physical, functional, and emotional) dimensions. Moreover, ET cases with marked voice tremor on examination had a level of self-reported voice handicap that was similar to that observed in patients with PD.

description: Αντικείμενο της παρούσας διατριβής είναι η ανίχνευση βλαβών σε κατασκευές και συγκεκριμένα σε ράβδους και πλάκες με τη χρήση κυματικής διάδοσης. Οι μέθοδοι ανάλυσης που χρησιμοποιήθηκαν ήταν η κατανομή Smoothed pseudo-Wigner(SPWD), ο συνεχής μετασχηματισμός κυματιδίων(CWT) και ο μετασχηματισμός Hilbert-Huang(HHT). Οσον αφορά στις ράβδους αναλύθηκαν σήματα εγκάρσιων κυμάτων που προέκυψαν είτε μέσω προσομοίωση είτε από πειρατικές μετρήσεις. τα θεωρητικά σήματα προέκυψαν μέσω μοντελοποίησης της ράβδου με βάση το μοντέλο Euler-Bernoulli. Σκοπός της ανάλυσης ήταν αρχικά η μελέτη της διασποράς που παρουσιάζει η εγκάρσια κυματική διάδοση σε ράβδο χωρίς ρωγμή και στη συνέχεια η ανίχνευση των χαρακτηριστικών μιας ρωγμής που εισήχθη στη ράβδο. Τόσο ο υπολογισμός της ταχύτητας ομάδας όσο και η ανίχνευση της ρωγμής έγιναν με μεγάλη ακρίβεια. Παράλληλα έγινε και μια σύγκριση των παραπάνω τριών μεθοδολογιών(SPWD,CWT,HHT) στην αποτελεσματικότητά τους να αναλύσουν σήματα κυματικής διάδοσης. Η μέθοδος SPWD αποδείχθη η καταλληλότερη στην ανάλυση εγκάρσιων κυμάτων. Στην περίπτωση της πλάκας η κυματική διάδοση είναι πιο σύνθετη, αφού διεγείρονται δύο κύριοι τύποι κυμάτων, τα επιφανειακά κύματα Rayleigh και τα κύματα Lamb(συμμετρικό και αντισυμμετρικό). Η μελέτη των χαρακτηριστικών της ρωγμής έγινε με χρήση των κυμάτων Rayleigh, τα οποία δεν παρουσιάζουν διασπορά, με πολύ καλή ακρίβεια
description: The goal of this phd thesis is damage detection in structures using wave propagation. The time-frequency representations used for analysing the waves are the Smoothed pseudo-Winger distribution(SPWD), the continuous wavelet transform(CWT) and the Hilbert-Huand transform(HHT). The transverse waves propagating in a beam were analysed in two particular cases; theoretical and experimental waves. The analysis aimed at two particular cases; theoretical and experimental waves. The analysis aimed at two aspects; first the study of the dispersion characteristics appearing in transverse wave propagation in a beam without cracks. And second, the detection of a crack that was introduced to the beam. The group velocity curve and the characteristics of the crack were calculated with very good accuracy. Furthermore, the effectiveness of the three above-mentioned time-frequency methods(SPWD, CWT, HHT) in analysing wave signals was compared and SPWD appeared to be the appearence of surface Rayleigh waves and Lamb waves. The identification of crack characteristics was performed using the non-dispersive Rayleigh waves with very good accuracy

description: Background: There is an increasing awareness that patients with essential tremor (ET) may exhibit non-motor features, including cognitive dysfunction. Yet there are surprisingly few data in ET on the association, if any, between cognitive dysfunction and motor dysfunction (i.e., tremor severity). Establishing links between the cognitive and motor features of ET would imply that the two share a common underlying pathogenic process. Recent neuroimaging data support this notion. Methods: ET cases were enrolled in a clinical–pathological study at Columbia University Medical Center, New York. The Folstein Mini-Mental State Examination (FMMSE) and Modified Mini Mental Status Examination (mMMSE) were administered. Action tremor was rated with a total tremor score (TTS). Results: There were 161 ET cases (mean age 83.9±5.7 years, median FMMSE 28, median mMMSE 50). The FMMSE and mMMSE were inversely correlated with the TTS (r = −0.22, p = 0.005; and r = −0.17, p = 0.029). The association, while statistically significant, was modest in magnitude. In linear regression models that adjusted for age, gender, and education, the association between cognitive test scores and TTS remained robust (p<0.001). After excluding 68 (42.2%) cases taking ET medications with potential cognitive side effects, results remained unchanged. Conclusions: Each of the two cognitive test scores was associated with tremor severity such that greater cognitive dysfunction occurred in cases with more marked tremor. These data support recent imaging data, which suggest that the cerebellar neurodegeneration underlying ET may be involved in the expression of cognitive symptoms in ET.
