Middle Ear Myoclonus: Two Informative Cases and a Systematic Discussion of Myogenic Tinnitus
Creators: name: Ellenstein, Aviva
name: Yusuf, Nadia
name: Hallett, Mark
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2013

description: Background: The term middle ear myoclonus (MEM) has been invoked to explain symptoms of tinnitus presumably caused by the dysfunctional movement of either of the two muscles that insert in the middle ear: tensor tympani and stapedius. MEM has been characterized through heterogeneous case reports in the otolaryngology literature, where clinical presentation is variable, phenomenology is scarcely described, the pathogenic muscle is usually not specified, natural history is unknown, and the presumptive definitive treatment, tensor tympani or stapedius tendon lysis, is inconsistently effective. It is not surprising that no unique acoustogenic mechanism or pathophysiologic process has been identified to explain MEM, one of several descriptive diagnoses associated with the complicated disorders of myogenic tinnitus. Methods: Here, we explore MEM from the neurologist’s perspective. Following the detailed descriptions of two informative cases from our clinic, we systematically evaluate the different mechanisms and movement disorder phenomena that could lead to a diagnosis of MEM. Results: From a functional neuroanatomic perspective, we explain how tensor tympani MEM is best explained as a form of peritubal myogenic tinnitus, similar to the related disorder of essential palatal tremor. From a pathogenic perspective, we discuss how MEM symptomatology may reflect different mechanical and neurologic processes. We emphasize the diagnostic imperative to recognize when myogenic tinnitus is consistent with a psychogenic origin. Discussion: Both individual patient care and further elucidation of MEM will rely on more detailed clinical characterization as well as multidisciplinary input from neurology, otolaryngology, and dentistry.

description: Solar activity in all its varied manifestations is driven by the magnetic field. Particularly important for many purposes are two global quantities, the Sun's total and open magnetic flux, which can be computed from sunspot number records using models. Such sunspot-driven models, however, do not take into account the presence of magnetic flux during grand minima, such as the Maunder minimum. Here we present a major update of a widely used simple model, which now takes into account the observation that the distribution of all magnetic features on the Sun follows a single power law. The exponent of the power law changes over the solar cycle. This allows for the emergence of small-scale magnetic flux even when no sunspots are present for multiple decades and leads to non-zero total and open magnetic flux also in the deepest grand minima, such as the Maunder minimum, thus overcoming a major shortcoming of the earlier models. The results of the updated model compare well with the available observations and reconstructions of the solar total and open magnetic flux. This opens up the possibility of improved reconstructions of sunspot number from time series of cosmogenic isotope production rate.
Tic Modulation Using Sensory Tricks
Creators: name: Gilbert, Rebecca Wolf
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2013

description: Background: A sensory trick, or geste antagoniste, is defined as a physical gesture (such as a touch on a particular body part) that mitigates the production of an involuntary movement. This phenomenon is most commonly described as a feature of dystonia. Here we present a case of successful modulation of tics using sensory tricks. Case Report:: A case report and video are presented. The case and video demonstrate a 19-year-old male who successfully controlled his tics with various sensory tricks. Discussion: It is underappreciated by movement disorder physicians that sensory tricks can play a role in tics. Introducing this concept to patients could potentially help in tic control. In addition, understanding the pathophysiological underpinnings of sensory tricks could help in the understanding of the pathophysiology of tics.

description: The hyperfine splittings in heavy quarkonia are studied using new experimental data on the di-electron widths. The smearing of the spin-spin interaction is taken into account, while the radius of smearing is fixed by the known $J/ψ-η_c(1S)$ and $ψ(2S)-η'_c(2S)$ splittings and appears to be small, $r_{ss} \approx 0.06$ fm. Nevertheless, even with such a small radius an essential suppression of the hyperfine splittings ($\sim 50%)$ is observed in bottomonium. For the $nS b\bar b$ states $(n=1,2,...6)$ the values we predict (in MeV) are 28, 12, 10, 6, 6, and 3, respectively. In single-channel approximation for the $3S$ and $4S$ charmonium states the splittings 16(2) MeV and 12(4) MeV are obtained.

An investigation into the developmental differences between reading delayed and successful reading students
Creators: name: Loy, Richard Douglas
Publisher: name: University of British Columbia
Year: 2011

description: Some school psychologists have made a practice of using adverse incidents in a child's early development as the basis for diagnosing children's reading difficulties and attributing those incidents to a possible organic base. However, the previous research has not been wholely supportive of a link between developmental history concerns and the acquisition of reading related skills. Thus, this research was intended to determine which incidents in the reported developmental history provided the best predictors of later reading difficulty. The developmental history form from the U.B.C. Education Clinic was used as the data gathering instrument and requested parental information about the child's family background, pregnacy and birthing factors, acquisition of developmental milestones, and health history. This instrument was chosen as it is uniformly completed by the U.B.C. school psychology students. This research was also intended to determine which areas of the form were the most effective in predicting later reading difficulties. Obtained samples of successful reading students (n=28) and delayed readers (n=35) were compared in terms of the significant incidents reported in their developmental histories. Results did substantiate some of the previous research in terms of the family background characteristics, pregnancy and birth concerns, and developmental milestone profile, previously associated with later reading difficulty. No significant incidents were noted in the health history section though it was concluded that valuable information appeared in all sections of the current developmental history form. However, this research design did not allow for predictive statistics as initially intended due to the qualitative nature of the data collected.

description: Relativistically moving dielectric perturbations can be used to manipulate light in new and exciting ways beyond the capabilities of traditional nonlinear optics. Adiabatic interaction with the moving front modulates the wave simultaneously in both space and time, and manifests a front-induced transition in both wave vector and frequency yielding exotic effects including non-reciprocity and time-reversal. Here, we introduce a technique called SLIPSTREAM, Spacetime Light-Induced Photonic STRucturEs for Advanced Manipulation. The technique is based on the creation of relativistic fronts in a semiconductor-filled planar waveguide by photoexcitation of mobile charge carriers. Here we demonstrate the capabilities of SLIPSTREAM for novel manipulation of THz light pulses through relativistic front-induced transitions. In the sub-luminal front velocity regime, we generate temporally stretched THz waveforms, with a quasi-static field lasting for several picoseconds tunable with the front interaction distance. In the super-luminal regime, the carrier front outpaces the THz pulse and a time-reversal operation is performed via a front-induced intra-band transition. We anticipate our platform will be a versatile tool for future applications in the THz spectral band requiring direct and advanced control of light at the sub-cycle level.
Shell Shock: Psychogenic Gait and Other Movement Disorders - A Film Review
Creators: name: Moscovich, Mariana
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2013

description: Background: The psychological pressure on soldiers during World War I (WWI) and other military conflicts has resulted in many reported cases of psychogenic gait as well as other movement disorders. In this paper, psychogenic movement disorders captured in the WWI film footage “War Neuroses” is reanalyzed. Methods: Two movement disorders specialists re-examined film images of 21 WWI patients with various and presumed psychogenic manifestations, pre- and post treatment. The film was recorded by Arthur Hurst, a general physician with an interest in neurology. Results: All 21 subjects were males, and all presented with symptoms relating to war trauma or a psychological stressor (e.g., being buried, shrapnel wounds, concussion, or trench fever). The most common presenting feature was a gait disorder, either pure or mixed with another movement disorder (15), followed by retrograde amnesia (2), abnormal postures (pure dystonia) (1), facial spasm (1), head tremor (1), “hyperthyroidism-hyperadrenalism” (1). Nineteen patients received treatment, and the treatment was identified in nine cases. In most cases, treatment was short and patients improved almost immediately. Occupational therapy was the most common treatment. Other effective methods were hypnosis (1), relaxation (1), passive movements (2), and probable “persuasion and re-education” (6). Discussion: The high success rate in treating psychogenic disorders in Hurst's film would be considered impressive by modern standards, and has raised doubt in recent years as to whether parts of the film were staged and/or acted.

description: Background: Sydenham's chorea (SC) is the most common type of acquired chorea in childhood. In some cases, symptoms (most commonly described in terms of neurological signs) last up to 2 years, and many cases relapse. This report describes the clinical course in terms of functional abilities following diagnosis of SC. Case report: Standardized assessments across the domains of activity and participation were administered following diagnosis, prior to and following treatment with haloperidol to measure treatment response and identify occupational therapy intervention needs. SC was observed to significantly reduce the child's participation and independence in activities of daily living. In this case, the standardized assessments administered highlighted difficulties with both motor and process skills. At 1 week after commencing haloperidol, both motor and process skills had improved. Clinically significant changes in self-care and mobility were noted with less improvement with handwriting. At 9 weeks, most symptoms and functional difficulties had resolved. Discussion: Given the process difficulties detected in this case, and the possibility of enduring symptoms, the use of functional assessments is advocated in the routine management of SC. These findings illustrate the potential for motor and non-motor sequelae in acute childhood movement disorders and related functional disabling consequences.

description: Metal-organic frameworks (MOFs), which are self-assemblies of metal ions and organic ligands, provide a tunable platform to search a new state of matter. A two-dimensional (2D) perfect kagome lattice, whose geometrical frustration is a key to realizing quantum spin liquids, has been formed in the $π$-${d}$ conjugated 2D MOF [Cu$_{3}$(C$_{6}$S$_{6}$)]$_{n}$ (Cu-BHT). The recent discovery of its superconductivity with a critical temperature $T_{\rm c}$ of 0.25\,kelvin raises fundamental questions about the nature of electron pairing. Here, we show that Cu-BHT is a strongly correlated unconventional superconductor with extremely low superfluid density. A nonexponential temperature dependence of superfluid density is observed, indicating the possible presence of superconducting gap nodes. The magnitude of superfluid density is much smaller than those in conventional superconductors, and follows the Uemura's relation of strongly correlated superconductors. These results imply that the unconventional superconductivity in Cu-BHT originates from electron correlations related to spin fluctuations of kagome lattice.

description: Le financement bancaire des activités agricoles au Mali face à la capacité de remboursement des agriculteurs ruraux. Pour mieux étayer notre travail, nous avons pris le cas de la Banque Nationale de Développement Agricole du Mali (BNDA) comme champ d’étude. La question centrale  est de savoir si les produits et services offerts par la BNDA sont en adéquation avec le niveau de revenu de la population rurale au Mali. Afin de mener à bien notre recherche, nous avons adopté un positionnement interpretativiste accompagné de démarche qualitative. Nos outils de recueil de données sont : l’observation participante, l’entretien et la revue documentaire. Nous avons dégagé comme résultat que les produits et services offerts par la BNDA sont en adéquation avec le niveau de revenu des populations rurales. Cela étant, nous avons toutefois formulé quelques recommandations qui pourraient bénéficier à la BNDA dans sa mission de financement pour le développement du secteur agricole. Comme principales recommandations l’accent devra être mis sur le pouvoir de louer à bail des matériels agricoles, des entrepôts et des installations de transformation et de pouvoir s’appuyer non seulement sur le recensement agricole, mais aussi sur une analyse plus approfondie de la structure et de la santé institutionnelles des coopératives de producteurs.

description: We consider a multigravity approach to spacetime foam. As an application we give indications on the computation of the cosmological constant, considered as an eigenvalue of a Sturm-Liouville problem. A variational approach with Gaussian trial wave functionals is used as a method to study such a problem. We approximate the equation to one loop in a Schwarzschild background and a zeta function regularization is involved to handle with divergences. The regularization is closely related to the subtraction procedure appearing in the computation of Casimir energy in a curved background. A renormalization procedure is introduced to remove the infinities together with a renormalization group equation.

Year: 2013

description: Background:Adult-onset focal lower extremity (LE) dystonia is rare, but there have recently been a number of case series that have reported an idiopathic variant triggered during ambulation. Methods:We describe nine patients with idiopathic, focal task-specific LE dystonia. We conducted a comparative analysis that included our cohort and several recently published case series to further characterize the disorder. Results:A total of 48 patients (37 female, 11 male) were compared. The average age of onset was 48 years; 36 patients had distal extremity involvement (75%), 5 proximal (10%), and 7 both proximal and distal (15%). Among 33 patients in which the dystonic side was known, 20 were affected on the left (61%). Inversion of the foot with flexion of one or more toes was the most prevalent pattern in those with distal extremity involvement. Discussion:This is a novel task-specific dystonia triggered during ambulation that is often misdiagnosed as an orthopedic or psychogenic issue.

description: Tom Bridgeland constructed explicit stability conditions on K3 surfaces. This paper attempts to shed more light on these particular examples, especially on the hearts of the underlying t-structures. We prove that two K3 surfaces X and X' are derived equivalent if and only if there exist complexified polarizations B+iw and B'+iw' such that the associated abelian categories A(B+iw) and A(B'+iw') are equivalent. We study in detail the minimal objects of A(B+iw) and investigate stability under Fourier-Mukai transform.

REM Sleep Behavior Disorder and Prodromal Neurodegeneration - Where are We Headed?
Creators: name: Postuma, Ronald B

Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2013

description: Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by loss of normal atonia during REM sleep, such that patients appear to act out their dreams. The most important implication of research into this area is that patients with idiopathic RBD are at very high risk of developing synucleinmediated neurodegenerative disease (Parkinson's disease [PD], dementia with Lewy bodies [DLB], and multiple system atrophy), with risk estimates that approximate 40–65% at 10 years. Thus, RBD disorder is a very strong feature of prodromal synucleinopathy. This provides several opportunities for future research. First, patients with REM sleep behavior disorder can be studied to test other predictors of disease, which could potentially be applied to the general population. These studies have demonstrated that olfactory loss, decreased color vision, slowing on quantitative motor testing, and abnormal substantia nigra neuroimaging findings can predict clinical synucleinopathy. Second, prospectively studying patients with RBD allows a completely unprecedented opportunity to directly evaluate patients as they transition into clinical neurodegenerative disease. Studies assessing progression of markers of neurodegeneration in prodromal PD are beginning to appear. Third, RBD are very promising subjects for neuroprotective therapy trials because they have a high risk of disease conversion with a sufficiently long latency, which provides an opportunity for early intervention. As RBD research expands, collaboration between centers will become increasingly essential.

description: The Zeeman effect is of limited utility for probing the magnetism of the quiet solar chromosphere. The Hanle effect in some spectral lines is sensitive to such magnetism, but the interpretation of the scattering polarization signals requires taking into account that the chromospheric plasma is highly inhomogeneous and dynamic (i.e., that the magnetic field is not the only cause of symmetry breaking). Here we investigate the reliability of a well-known formula for mapping the azimuth of chromospheric magnetic fields directly from the scattering polarization observed in the \ion{Ca}{2}~8542~Å\, line, which is typically in the saturation regime of the Hanle effect. To this end, we use the Stokes profiles of the \ion{Ca}{2}~8542~Å\, line computed with the PORTA radiative transfer code in a three-dimensional (3D) model of the solar chromosphere, degrading them to mimic spectropolarimetric observations for a range of telescope apertures and noise levels. The simulated observations are used to obtain the magnetic field azimuth at each point of the field of view, which we compare with the actual values within the 3D model. We show that, apart from intrinsic ambiguities, the method provides solid results. Their accuracy depends more on the noise level than on the telescope diameter. Large-aperture solar telescopes, like DKIST and EST, are needed to achieve the required noise-to-signal ratios using reasonable exposure times.

description: Background: Post-stroke movement disorders occur in up to 4% of stroke patients. The movements can be complex and difficult to classify, which presents challenges when attempting to understand the clinical phenomenology and provide appropriate treatment. Case Report: We present a 64-year-old male with an unusual movement in the arm contralateral to his ischemic stroke. The primary feature of the movement was an involuntary elevation of the arm, occurring only when he was walking. Discussion: The differential diagnosis includes dystonia, spontaneous arm levitation, synkinesis, and spasticity. We discuss each of these diagnostic possibilities in detail.

Detection of nutrient stress in Douglas-fir seedlings using spectroradiometer data
Creators: name: Bracher, Grant Allan
Publisher: name: University of British Columbia
Year: 2011

description: Narrow-band spectral reflectance measurements in the visible and near-infrared region of the spectrum were investigated for the detection of nutrient deficiencies, and estimating the foliar concentrations of nitrogen, phosphorus, sulphur, and total chlorophyll. One-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were treated with 24 nutrient solutions containing nitrogen, phosphorus and sulphur levels ranging from 1 to 400 mg/L. After one growing season, newly matured needles were harvested, spectral reflectance measured from 400 to 1100 nm, and foliar samples analyzed for nutrient and chlorophyll levels. Several nutrient deficiencies were diagnosed. There were no unique changes in spectral reflectance which could be attributed to a specific nutrient deficiency; rather changes in reflectance were non-specific responses influenced by how varying nutrient levels affected total chlorophyll concentration. All deficiencies caused decreases in total chlorophyll, thus demonstrating the value of total chlorophyll as an indicator of nutrient stress. Correlation coefficients were calculated describing the degree of association between foliar nitrogen, phosphorus, sulphur and total chlorophyll, and the following spectral parameters: the wavelength of the red edge, percent spectral reflectance at 554 and 630 nm (red rise), and 15 vegetation indices (VIs). VIs were first determined using combinations of spectral reflectances at 480, 554, 800 nm and the wavelength of the red well (674 nm; called red well VIs), and then recalculated using red rise (called red rise VIs) rather than red well measurements to see if greater correlation with foliar constituents could be obtained. Although the use of red rise measurements in the calculation of VIs 1, 2, 3, 12 and 14 resulted in higher correlation coefficients, differences between coefficients were seldom statistically significant. Red well and red rise VI15 were most correlated with the needle nitrogen content of individual Douglas-fir, red rise VI10 with phosphorus, and spectral reflectance at 554 nm and red well VI15 with total chlorophyll. These parameters proved useful indicators of relative nitrogen, phosphorus and total chlorophyll content. None of the VIs or other spectral parameters followed the same relationship with foliar sulphur for the sulphur, nitrogen and phosphorus treatments; consequently, none were deemed suitable for sulphur estimation.

description: Digital contact tracing can limit the spread of infectious diseases. Nevertheless, there remain barriers to attaining sufficient adoption. In this study, we investigate how willingness to participate in contact tracing is affected by two critical factors: the modes of data collection and the type of data collected. We conducted a scenario-based survey study among 220 respondents in the United States (U.S.) to understand their perceptions about contact tracing associated with automated and manual contact tracing methods. The findings indicate a promising use of smartphones and a combination of public health officials and medical health records as information sources. Through a quantitative analysis, we describe how different modalities and individual demographic factors may affect user compliance in providing four key pieces of information to contact tracing.

Συμπερασματικά, η βόσκηση γιδιών και προβάτων μέχρι το όριο της κανονικής χρήσης δημιούργησε επιθυμητές συνθήκες για το λαγό και επομένως θεωρείται ότι η διττή εκμετάλλευση των λιβαδικών οικοσυστημάτων, κτηνοτροφική και θηραματική, είναι εφικτή
description: The purpose of this research was to investigate if goats, sheep and brown have can coexist in a typical Mediterranean rangeland, by studying their feeding habits as well as the effects of grazing intensity by livestick on habitat use by brown haves. Diet composition was estimated by microhistorical analysis of faeces and habitat use using the pellet-count method. The diet composition of livestock was dissimilar in relation with that of hare. Hare used more intensively the moderately grazed pastures with the lowest quantity of standing biomass. Conclusively, goats and sheep grazing, under the threshold of proper use, created favorable conditions for hare and thus, it is considered that dual exploitation of range ecosystems, livestock and game is attainable

description: Βασικός στόχος της διατριβής είναι ο προσδιορισμός των παραγόντων που επηρεάζουν και τον τρόπο επίδρασης στην απόδοση εξαγωγών των ελληνικών οινοποιητικών επιχειρήσεων. Παράλληλα γίνεται μία προσπάθεια ομαδοποίησης των συγκεκριμένων επιχειρήσεων με βάση αντιλήψεις της διοίκησης για τη συχνότητα εμφάνισης ενός αριθμού εξαγωγικών εμποδίων. Δεδομένα συγκεντρώνονται μέσω ταχυδρομικής έρευνας σε ελληνικές διερευνητικές επιχειρήσεις και η επεξεργασία τους πραγματοποιείται με την εφαρμογή διερευνητικής παραγοντικής και επιβεβαιωτικής παραγοντικής ανάλυσης. Για την επίτευξη του βασικού στόχου της έρευνας καθώς και για την ομαδοποίηση των επιχειρήσεων εφαρμόζονται η ανάλυση διαδρομών και η ανάλυση σε συστάδες αντίστοιχα. Κύριο συμπέρασμα είναι ότι οι ελληνικές οινοποιητικές επιχειρήσεις θα πρέπει να εκμεταλλευθούν το ανταγωνιστικό εξαγωγικό τους πλεονέκτημα(που αφορά την εξαγωγική τους ικανότητα, την προσαρμογή προϊόντος, την ανταγωνιστική τιμή, την υποστήριξη προς το διανομέα και τη γνώση των εξαγωγικών δικτύων διανομής) σε ένα ιδιαίτερα εχθρικό και ανταγωνιστικό περιβάλλον και μέσω της ανταλλαγής πληροφοριών και της συνεργασίας με τα δίκτυα διανομής στο εξωτερικό να επιτύχουν υψηλά επίπεδα απόδοσης εξαγωγών. Η ομαδοποίηση έχει ωε αποτέλεσμα τη δημιουργία τριών ομάδων επιχειρήσεων : δραστήριοι ανταγωνιστικοί εξαγωγείς, διερευνητικοί-μειονεκτικοί εξαγωγείς και προσαρμοστικοί-διαλλακτικοί εξαγωγείς. Η ανάλυση κια συζήτηση των αποτελεσμάτων γίνεται βάσει της θεωρίας εξαγωγικού μάρκετινγκ
description: The main objective of the proposed dissertation is to identify the determinants of export performance of Greek wine firms. A endeavor is also made to classify wine firms based on managerial perceptions about the frequency of appearance of export impediments. Primary data are collected through a mail syrvey of Greek wine firms involved in exports and are analysed via exploratory factor analysis ans confirmatory factor analysis. Additionally, path analysis is applied to achieve the main objective of the study, whereas clyster analysis is used to categorise wine firms. Findings demostrate that wine firms should exploit their export competitive advantage(in terms of export competence, product adaptation, competitive price, support to the distributor & export channel knowledge) in a hostile & competitive external environment and through an integrated relationship with distributors abroad to attain optimal levels of export perfomance. Moreover, Greek wine firms are classiffied as : active-competitive exporters, exploratory-disadvantegeous exportes & adaptive-conciliatory exporters. The results are discussed based on export management literature. Theoretical & managend implications possible research avenues are drawn

description: Game dynamics in which three or more strategies are cyclically competitive, as represented by the rock-scissors-paper game, have attracted practical and theoretical interests. In evolutionary dynamics, cyclic competition results in oscillatory dynamics of densities of individual strategists. In finite-size populations, it is known that oscillations blow up until all but one strategies are eradicated if without mutation. In the present paper, we formalize replicator dynamics with players that have different adaptation rates. We show analytically and numerically that the heterogeneous adaptation rate suppresses the oscillation amplitude. In social dilemma games with cyclically competing strategies and homogeneous adaptation rates, altruistic strategies are often relatively weak and cannot survive in finite-size populations. In such situations, heterogeneous adaptation rates save coexistence of different strategies and hence promote altruism. When one strategy dominates the others without cyclic competition, fast adaptors earn more than slow adaptors. When not, mixture of fast and slow adaptors stabilizes population dynamics, and slow adaptation does not imply inefficiency for a player.

description: Background: The aim was to elucidate clinical trial efficacy, safety, and dosing practices of abobotulinumtoxinA (ABO) treatment in adult patients with blepharospasm and hemifacial spasm. To date, most literature reviews for blepharospasm and hemifacial spasm have examined the effectiveness of all botulinum neurotoxin type A products as a class. However, differences in dosing units and recommended schemes provide a clear rationale for reviewing each product separately. Methods: A systematic literature review was performed to identify randomized controlled trials and other comparative clinical studies of ABO in the treatment of blepharospasm and hemifacial spasm published in English between January 1991 and March 2015. Medical literature databases (PubMed, Cochrane library, EMBASE) were searched. A total of five primary publications that evaluated ABO for the management of blepharospasm and hemifacial spasm were identified and summarized. Results: Data included 374 subjects with blepharospasm and 172 subjects with hemifacial spasm treated with ABO. Total ABO doses ranged between 80 and 340 U for blepharospasm and 25 and 85 U for hemifacial spasm, depending on the severity of the clinical condition. All studies showed statistically significant benefits for the treatment of blepharospasm and hemifacial spasm. ABO was generally well tolerated across the individual studies. Adverse events considered to be associated with ABO treatment included: ptosis, tearing, blurred vision, double vision, dry eyes, and facial weakness. Discussion: These data from 5 randomized clinical studies represents the available evidence base of ABO in blepharospasm and hemifacial spasm. Future studies in this area will add to this evidence base.

description: Background: Focal treatment of Parkinson’s disease tremor by botulinum toxin type A incobotulinumtoxinA (BoNT-A) injections has been inadequately investigated and at best provides modest relief with significant muscle weakness. Complexity of multi-joint tremulous movements results in non-individualized dosing regimens. This 38-week open-label study used kinematic technology to guide muscle selection and improve efficacy of incobotulinumtoxinA (BoNT-A) injections for Parkinson’s disease tremor. Methods: Participants (n=28) attended study visits at weeks 0, 6, 16, 22, 32, and 38, and were injected with BoNT-A at weeks 0, 16, and 32. During each visit, clinical tremor scales, the Unified Parkinson’s Disease Rating Scale (UPDRS) and the Fahn–Tolosa–Marin (FTM), and kinematic assessments were conducted. Participants performed rest and postural scripted tasks with motion sensors placed over the wrist, elbow, and shoulder joints where tremor was quantified by angular root mean square (RMS) amplitude in multiple degrees of freedom at each joint. Injection parameters were determined using the clinician’s interpretation of which muscles would contribute to the upper limb tremor biomechanics analyzed kinematically. Results: Kinematic measures of tremor amplitude allowed detailed segmentation of tremor into directional components at each arm joint permitting a statistically significant decrease in mean UPDRS item 20 (rest tremor) at week 16 (p=0.006) and at week 32 (p=0.014), and in FTM tremor severity scores at week 6 (p=0.024). Ten participants perceived mild muscle weakness following the third treatment, which did not interfere with performing activities of daily living. Discussion: Kinematics is a simple method for standardizing assessments and treatment of upper limb Parkinson’s disease tremor, thereby personalizing tremor therapy and optimizing the effect of BoNT-A injections for Parkinson’s disease tremor.

description: We present measurements of the fourth and fifth cumulants of the distribution of transmitted charge in a tunable quantum dot. We investigate how the measured statistics is influenced by the finite bandwidth of the detector and by the finite measurement time. By including the detector when modeling the system, we use the theory of full counting statistics to calculate the noise levels for the combined system. The predictions of the finite-bandwidth model are in good agreement with measured data.

description: Τα δασικά οικοσυστήματα αλλά και οι φυσικοί πόροι γενικώτερα, σήμερα περισσότερο από ποτέ βρίσκονται στο επίκεντρο της κοινής γνώμης. Το Δασολόγιο το οποίο θεσμοθετήθηκε τη δεκαετία του 1970, είναι ένα έμπρακτο παράδειγμα του ενδιαφέροντος που υπάρχει για την καταγραφή του δασικού πλούτου της χώρας μας. Αντικείμενο έρευνας στη παρούσα διατριβή αποτέλεσε η διερεύνηση της δυνατότητας χρησιμοποίησης εξελιγμένων δορυφορικών δεδομένων και της επεξεργασίας τους με νέες τεχνικές για την εξαγωγή πληροφοριών, ικανών να χρησιμοποιηθούν για την κατάρτιση του δασολογίου. Η ευρύτερη περιοχή μελέτης ήταν το Πανεπιστημιακό δάσος Ταξιάρχη στο Ν. Χαλκιδικής. Οι δορυφορικές εικόνες μετά τη διόρθωσή τους, συγχωνεύτηκαν με σκοπό τη βελτίωση της χωρικής ανάλυσης της πολυφασματικής εικόνας. Μετά τη διερεύνηση της βέλτιστης κλίμακας και των ιδανικών παραθύρων για την ποσοτικοποίηση της χωρικής αυτοσυσχέτισης, πραγματοποιήθηκαν ταξινομήσεις για τη διάκριση δάσους-δασικής έκτασης και πολυγώνων βλάστησης. Η ανάλυση αποδείχτηκε ικανοποιητική, για την επίτευξη των στόχων, ενώ υπάρχουν περιθώρια βελτίωσης
description: Forest ecosystems and natural resources in general, today more than over are in focus at the public. Dasologio which was originally in introduced in the legislation during the 1970 decade it is a proof about the concern and the attention paid to forest ecosystems in our country. Objective of this thesis was the evaluation of the possible use advanced satellite data and their processing with new techniques in order to extract informations for the compiling of Dasologio. The study area was the University forest of Taxiarhi, in the Perfecture of Halkidiki. The satellite data after its pre-processing, were merged in order to enhance the spatied resolution of the multispectral image. After determining the optimal spatial resolution and the optimal window size for producing texture images, dassifications were vegetations polygons.
