description: Aim of the study is the early diagnosis of the Developmental dysplasia of the hip(DDH) and the follow up monitoring by ultrasonography. 500 hips, of 250 newborns and infants up to 6 months of age, with at-risk-factors or positive clinical findings of DDH were examined sonographically. The first section of the study includes general considerations in hip sonography of DDH(Etiology and causative factors, embryology, pathology, physical and radiological findings), a brief review of the history of the hip sonography, a detailed description of the various morphological and dynamic sonographic methods and the imaging of the normal hip. The second section includes the material and methods as well as an analysis of sonographic findings in neonates. Our results are discussed in correlation with the international literature according to the technique of hip sonography, the age-related changes of the hip with regard to sonography, the reliability of the method, the usefulness as a regular or selective screening test, the determination of the timing of initial examination or screening, and the management of patients. Prevention of late-diagnosed case of DDH is discussed as well as the possibility of over diagnosis and unnecessary treatment due to the sensitivity of the method. Sonography is very useful for the detection of developmental dysplasia of the hip and can demostrate abnormalities not found on clinical examination
Platelet monoamine oxidase type B (MAO-B) activity in psychopathy
Creators: name: Gretton, Heather Margaret
Publisher: name: University of British Columbia
Year: 2011

description: Studies of platelet MAO-B activity have revealed a link between low platelet activity and psychiatric syndromes characterized by an inability to control impulses and to anticipate future consequences of behavior (Oreland, 1980; Gottfries, von Knorring, & Oreland, 1980). These characteristics are fundamental to the construct of psychopathy, and we might therefore expect that psychopathy is associated with low MAO activity. Indeed, some investigators have suggested that low platelet MAO-B activity is a potential marker for vulnerability to psychopathy (Schalling, Asberg, Edman, & Oreland, 1987). However, no study to date has directly examined the association between platelet MAO activity and psychometrically-sound indices of psychopathy. The present study measured platelet MAO-B activity in a sample of 54 male offenders, assessed with the Psychopathy Checklist-Revised (PCL-R; Hare, 1991). PCL-R scores were not significantly related to level of platelet MAO activity. The results are discussed in terms of methodological issues involved in conducting biochemical research.

description: The 2019 European Parliament elections seemingly fostered concerted political action among radical right parties (RRPs) to fortify their positions and mobilize publics on a pan-European scale. Digital platforms provide central infrastructure for networks among political actors and user interactions on the ground. Our study, therefore, investigates the intra- and transnational networking on Twitter established by RRPs’ strategic communication and user interactions. To understand how distinct political and media-related opportunity structures align with different intensities, types, and meanings of digital connections, we investigate the salience, actor types, and geographical scopes as well as the functions of digital connections within and across Twitter networks in Austria, France, Germany, Italy, Poland, and Sweden during the EP election campaigns. Our results indicate the influence of parties’ structural power position on networked communication: The ecologies around RRPs in government reflect their integration in national discourses and competition. The networks of RRPs in opposition display a self-referential campaign ecology for the promotion and distribution of candidates, content, and positions. Transnationality in these networks is structured by EU-level collaboration and driven by civil society and political entrepreneurs, who appear keener to mobilize across borders.
Lagrangian pair dispersion in upper-ocean turbulence in the presence of mixed-layer instabilities

description: Turbulence in the upper ocean in the submesoscale range (scales smaller than the deformation radius) plays an important role for the heat exchange with the atmosphere and for oceanic biogeochemistry. Its dynamics should strongly depend on the seasonal cycle and the associated mixed-layer instabilities. The latter are particularly relevant in winter and are responsible for the formation of energetic small scales that extend over the whole depth of the mixed layer. The knowledge of the transport properties of oceanic flows at depth, which is essential to understand the coupling between surface and interior dynamics, however, is still limited. By means of numerical simulations, we explore the Lagrangian dispersion properties of turbulent flows in a quasi-geostrophic model system allowing for both thermocline and mixed-layer instabilities. The results indicate that, when mixed-layer instabilities are present, the dispersion regime is local from the surface down to depths comparable with that of the interface with the thermocline, while in their absence dispersion quickly becomes nonlocal versus depth. We then identify the origin of such behavior in the existence of fine-scale energetic structures due to mixed-layer instabilities. We further discuss the effect of vertical shear on the Lagrangian particle spreading and address the correlation between the dispersion properties at the surface and at depth, which is relevant to assess the possibility of inferring the dynamical features of deeper flows from the more accessible surface ones.

description: We present approximative solutions to the neutrino evolution equation calculated by different methods. In a two neutrino framework, using the physical parameters which gives the main effects to neutrino oscillations from nu{e} to another flavors for L=3000Km and E=1GeV, the results for the transition probability calculated by using series solutions, by to take the neutrino evolution operator as a product of ordered partial operators and by numerical methods, for a linearly and sinusoidally varying matter density are compared. The extension to an arbitrary density profile is discussed and the evolution operator as a product of partial operators in the three neutrino case is obtained.

description: The 11-year solar cycle is the dominant pattern of solar activity reflecting the oscillatory dynamo mechanism in the Sun. Solar cycles were directly observed since 1700, while indirect proxies suggest their existence over a much longer period of time but generally without resolving individual cycles and their continuity. Here we reconstruct individual cycles for the last millennium using recent 14C data and state-of-the-art models. Starting with the 14C production rate determined from the so far most precise measurements of radiocarbon content in tree rings, solar activity is reconstructed in three physics-based steps: (1) Correction of the 14C production rate for the changing geomagnetic field; (2) Computation of the open solar magnetic flux; and (3) Conversion into sunspot numbers outside of grand minima. Solar activity is reconstructed for the period 971-1900 (85 individual cycles). This more than doubles the number of solar cycles known from direct solar observations. We found that lengths and strengths of well-defined cycles outside grand minima are consistent with those obtained from the direct sunspot observations after 1750. The validity of the Waldmeier rule is confirmed at a highly significant level. Solar activity is found to be in a deep grand minimum when the activity is mostly below the sunspot formation threshold, during about 250 years. Therefore, although considerable cyclic variability in 14C is seen even during grand minima, individual solar cycles can hardly be reliably resolved therein. Three potential solar particle events, ca. 994, 1052 and 1279 AD, are shown. A new about 1000-year long solar activity reconstruction, in the form of annual (pseudo) sunspot numbers with full assessment of uncertainties, is presented based on new high-precision 14C measurements and state-of-the-art models, more than doubling the number of individually resolved solar cycles.

description: Single electron spins in quantum dots are attractive for quantum communication because of their expected long coherence times. We propose a method to create entanglement between two remote spins based on the coincident detection of two photons emitted by the dots. Local nodes of several qubits can be realized using the dipole-dipole interaction between trions in neighboring dots and spectral addressing, allowing the realization of quantum repeater protocols. We have performed a detailed feasibility study of our proposal based on tight-binding calculations of quantum dot properties.

description: An appropriate gauge-invariant framework for the treatment of magnetized curvature and entropy modes is developed. It is shown that large-scale magnetic fields, present after neutrino decoupling, affect curvature and entropy perturbations. The evolution of different magnetized modes is then studied across the matter-radiation transition both analytically and numerically. From the observation that, after equality (but before decoupling) the (scalar) Sachs-Wolfe contribution must be (predominantly) adiabatic, constraints on the magnetic power spectra are deduced. The present results motivate the experimental analysis of more general initial conditions of CMB anisotropies (i.e. mixtures of magnetized adiabatic and isocurvature modes during the pre-decoupling phase). The role of the possible correlations between the different components of the fluctuations is partially discussed.

description: Many organic chemical reactions are governed by potential energy surfaces that have a region with the topographical features of a caldera. If the caldera has a symmetry then trajectories transiting the caldera region are observed to exhibit a phenomenon that is referred to as dynamical matching. Dynamical matching is a constraint that restricts the way in which a trajectory can exit the caldera based solely on how it enters the caldera. In this paper we show that bifurcations of the critical points of the caldera potential energy surface can destroy dynamical matching even when the symmetry of the caldera is not affected by the bifurcation.

description: Based on the catalog of merging galaxies in the Early Data Release (EDR) of the Sloan Digital Sky Survey (SDSS), the differences of star formation history between merging galaxies and field galaxies are studied statistically by means of three spectroscopic indicators the 4000-Å break strength, the Balmer absorption-line index, and the specific star formation rate. It is found that for early-type merging galaxies the interactions will not induce significant enhancement of the star-formation activity because of its stability and lack of cool gas. On the other hand, late-type merging galaxies always in general display more active star formation than field galaxies on different timescales within about 1Gyr. We also conclude that the mean stellar ages of late-type merging galaxies are younger than those of late-type field galaxies.

description: In the context of damage to DNA by low-energy electrons, we carry out calculations of electron scattering from tetrahydrofuran and phosphoric acid, models of the subunits in the DNA backbone, as a first step in simulating the electron capture process that occurs in the cell. In the case of tetrahydrofuran, we also compare with previous theoretical and experimental data. A comparison of the shape of the resonant structures to virtual orbitals is also performed to gain insight into the systematic connections with electron scattering from similar molecules and dissociative electron attachment experiments.

Calculations can reproduce well the $α$-decay widths of excited states in $^{8}$Be, $^{12}$C and $^{20}$Ne. For the nucleus $^{10}$Be, we discussed the $α$-decay widths with different shapes or decay modes, in order to understand the very different decay widths of two excited states. The widths of $^{6}$He decay from $^{12}$Be and $α$ decays from $^{13,14}$C are predicted, which could be useful for future experiments.

description: Background: Dystonia is a movement disorder with high heterogeneity regarding phenotypic appearance and etiology that occurs in both sporadic and familial forms. The etiology of the disease remains unknown. However, there is increasing evidence suggesting that a small number of gene alterations may lead to dystonia. Although pathogenic variants to the familial type of dystonia have been extensively reviewed and discussed, relatively little is known about the contribution of single-nucleotide polymorphisms (SNPs) to dystonia. This review focuses on the potential role of SNPs and other variants in dystonia susceptibility. Methods: We searched the PubMed database for peer-reviewed articles published in English, from its inception through January 2018, that concerned human studies of dystonia and genetic variants. The following search terms were included: “dystonia” in combination with the following terms: 1) “polymorphisms” and 2) “SNPs” as free words. Results: A total of 43 published studies regarding TOR1A, BDNF, DRD5, APOE, ARSG, NALC, OR4X2, COL4A1, TH, DDC, DBH, MAO, COMT, DAT, GCH1, PRKRA, MR-1, SGCE, ATP1A3, TAF1, THAP1, GNAL, DRD2, HLA-DRB, CBS, MTHFR, and MS genes, were included in the current review. Discussion: To date, a few variants, which are possibly involved in several molecular pathways, have been related to dystonia. Large cohort studies are needed to determine robust associations between variants and dystonia with adjustment for other potential cofounders, in order to elucidate the pathogenic mechanisms of dystonia and the net effect of the genes.

description: We perform a Bayesian analysis of the maximum mass $M_{\rm TOV}$ of neutron stars with a quark core, incorporating the observational data from tidal deformability of the GW170817 binary neutron star merger as detected by LIGO/Virgo and the mass and radius of PSR J0030+0451 as detected by \nicer. The analysis is performed under the assumption that the hadron-quark phase transition is of first order, where the low-density hadronic matter described in a unified manner by the soft QMF or the stiff DD2 equation of state (EOS) transforms into a high-density phase of quark matter modeled by the generic "Constant-sound-speed" (CSS) parameterization. The mass distribution measured for the $2.14 \,{\rm M}_{\odot}$ pulsar, MSP J0740+6620, is used as the lower limit on $M_{\rm TOV}$. We find the most probable values of the hybrid star maximum mass are $M_{\rm TOV}=2.36^{+0.49}_{-0.26}\,{\rm M}_{\odot}$ ($2.39^{+0.47}_{-0.28}\,{\rm M}_{\odot}$) for QMF (DD2), with an absolute upper bound around $2.85\,{\rm M}_{\odot}$, to the $90\%$ posterior credible level. Such results appear robust with respect to the uncertainties in the hadronic EOS. We also discuss astrophysical implications of this result, especially on the post-merger product of GW170817, short gamma-ray bursts, and other likely binary neutron star mergers.

description: The hydrodynamic response of the inviscid small shearing box model of a midplane section of a rotationally supported astrophysical disk is examined. An energy functional ${\cal E}$ is formulated for the general nonlinear problem. It is found that the fate of disturbances is related to the conservation of this quantity which, in turn, depends on the boundary conditions utilized: ${\cal E}$ is conserved for channel boundary conditions while it is not conserved in general for shearing box conditions. Linearized disturbances subject to channel boundary conditions have normal-modes described by Bessel Functions and are qualitatively governed by a quantity $Σ$ which is a measure of the ratio between the azimuthal and vertical wavelengths. Inertial oscillations ensue if $Σ>1$ - otherwise disturbances must in general be treated as an initial value problem. We reflect upon these results and offer a speculation.

description: Η μελέτη εστιάζεται σε δύο επίπεδα του μοντέλου ISO/OSI, ζεύξης και δικτύου. Αρχικά, μελετήθηκε το πρωτόκολλο πολλαπλής πρόσβασης ΕΥ-ΝΡΜΑ. Με στόχο την βελτίωση της αποδοτικότητας, σχεδιάστηκαν δύο πρωτόκολλα που μεταβάλλουν το μηχανισμό ανάθεσης προτεραιοτήτων. Επίσης, προτάθηκε εκτιμητής του προσφερόμενου φορτίου. Το προσαρμοστικό ΕΥ-ΝΡΜΑ με μεταβλητή αποκομιδή βελτιώνει περαιτέρω την αποδοτικότητα, προσθέτοντας ένα επιπλέον επίπεδο προσαρμοστικότητας, ενώ τέλος αξιολογήθηκε και το πρωτόκολλο και το πρωτόκολλο EDCF. Στο επίπεδο δικτύου, ποσοτικοποιήθηκε η σημασία των κατανεμημένων πυλών σε ένα κυψελοποιημένο δίκτυο, ενώ προτάθηκε πρωτόκολλο πολλαπλής πρόσβασης που επιτρέπει την ενεργοποίησή τους. Επίσης, προτάθηκε το πρωτόκολλο δρομολόγησης SNLSR, το οποίο χρησιμοποιεί τους αριθμούς ακολουθίας για την μείωση της πλεονάζουσας πληροφορίας τοπολογίας που εκπέμπεται στο δίκτυο
description: This study focuses on two layers of the ISO/OSI networking stack and namely the data link and the network layer. The behaviour of the medium access protocol EYNPMA was studied via both analytical and numerical means. Aiming at improving the efficiency, two protocols based on EY-NPMA have been designed(EY-NPMA/TP and EY-NPMA/ZP), which allow the dynamic upgrading of the priority levels of a subset of the network population. Also, a mechanism for estimating the offered load was designed and evaluated(adaptive EY-NPMA). Adaptive EY-NPMA with variable yield further improves the protocol efficiency by allowing the interaction between the elimination and the yield phases. Finally, the performance of the EDCF protocol was evaluated using numerical methods, while it was also compared with EY-NPMA and EY-NPMA/ZP. In the network layer, the value of distributed gateways was quantified in a clustered ad hoc network, while a medium access protocol which enables their usage was designed and evaluated. Also, the SNLSR routing protocol was proposed, which uses sequence numbers in order to reduce the transmission of redundant topology information in the network

description: We study dynamic fluctuation effects of $YBa_2Cu_3O_{7-δ}$ thin films in zero field around $T_c$ by doing frequency-dependent microwave conductivity measurements at different powers. The length scales probed in the experiments are varied systematically allowing us to analyze data which are not affected by the finite thickness of the films, and to observe single-parameter scaling. DC current-voltage characteristics have also been measured to independently probe fluctuations in the same samples. The combination of DC and microwave measurements allows us to precisely determine critical parameters. Our results give a dynamical scaling exponent $z=1.55\pm0.15$, which is consistent with model E-dynamics.

description: We study the elastic response of concentrated suspensions of rigid wire frame particles to a step strain. These particles are constructed from infinitely thin, rigid rods of length $L$. We specifically compare straight rod-like particles to bent and branched wire frames. In dense suspensions the wire frames are frozen in a disordered state by the topological entanglements between their arms. We present a simple, geometric method to find the scaling of the elastic stress with concentration in these glassy systems. We apply this method to a simple 2D model system where a test particle is placed on a plane and constrained by a random distribution of points with number density $ν$. Two striking differences between wire frame and rod suspensions are found: 1) The linear elasticity per particle for wire frames is very large, scaling like $ν^2 L^4$, whereas for rods it much smaller and independent of concentration. 2) Rods always shear thin but wire frames shear harden for densities less than $\sim \sqrt{K/k_B T L^4}$, where $K$ is the bending modulus of the particles. The deformation of wire frames is found to be important even for small strains, with the proportion of deformed particles at a particular strain, $γ$, being given by $(νL^2)^2 γ^2$. Our results agree well with a simple simulation of the 2D system.

Merging the Pathophysiology and Pharmacotherapy of Tics

description: Background: Anatomically, cortical-basal ganglia-thalamo-cortical (CBGTC) circuits have an essential role in the expression of tics. At the biochemical level, the proper conveyance of messages through these circuits requires several functionally integrated neurotransmitter systems. In this manuscript, evidence supporting proposed pathophysiological abnormalities, both anatomical and chemical is reviewed. In addition, the results of standard and emerging tic-suppressing therapies affecting nine separate neurotransmitter systems are discussed. The goal of this review is to integrate our current understanding of the pathophysiology of Tourette syndrome (TS) with present and proposed pharmacotherapies for tic suppression. Methods: For this manuscript, literature searches were conducted for both current basic science and clinical information in PubMed, Google-Scholar, and other scholarly journals to September 2018. Results: The precise primary site of abnormality for tics remains undetermined. Although many pathophysiologic hypotheses favor a specific abnormality of the cortex, striatum, or globus pallidus, others recognize essential influences from regions such as the thalamus, cerebellum, brainstem, and ventral striatum. Some prefer an alteration within direct and indirect pathways, whereas others believe this fails to recognize the multiple interactions within and between CBGTC circuits. Although research and clinical evidence supports involvement of the dopaminergic system, additional data emphasizes the potential roles for several other neurotransmitter systems. Discussion: A greater understanding of the primary neurochemical defect in TS would be extremely valuable for the development of new tic-suppressing therapies. Nevertheless, recognizing the varied and complex interactions that exist in a multi-neurotransmitter system, successful therapy may not require direct targeting of the primary abnormality.

description: We propose an active mechanism for coupling the quantized mode of a nanomechanical resonator to the persistent current in the loop of a superconducting Josephson junction (or phase slip) flux qubit. This coupling is independently controlled by an external coupling magnetic field. The whole system forms a novel solid-state cavity quantum electrodynamics (QED) architecture in the strong coupling limit. This architecture can be used to demonstrate quantum optics phenomena and coherently manipulate the qubit for quantum information processing. The coupling mechanism is applicable for more generalized situations where the superconducting Josephson junction system is a multi-level system.We also address the practical issues concerning experimental realization.

description: Ambipolar transport is a commonly occurring theme in semimetals and semiconductors. Here we present an analytical formulation of the conductivity for a two-band system. Electron and hole carrier densities and their respective conductivities are mapped into a two-dimensional unit-less phase space. Provided that one of the carrier densities is known, the dimensionless phase space can be probed through magnetoresistance measurements. This formulation of the two-band model for conductivity is applied to magnetoresistance experiments on Ca$_3$Ru$_2$O$_7$. While previous such measurements focused on the low-temperature limit, we cover a broad temperature range and find negative magnetoresistance in an intermediate interval below the electronic transition at 48 K. The low-temperature magnetoresistance in Ca$_3$Ru$_2$O$_7$ is consistent with a two-band structure. However, the model fails to describe the full temperature and magnetic field dependence. Negative magnetoresistance found in an intermediate temperature range is, for example, not captured by this model. We thus conclude that the electronic and magnetic structure in this intermediate temperature range render the system beyond the most simple two-band model.

description: Handball goalie's elbow affects quite a number of players. The purpose of this study was a)the presentation of a complete picture of the syndrome in high performance goalkeeprs b)the introduction of a program of muscular strengthening which aims at the prevention and management of the syndrome c)the examination of the influence of the program on the subjective sense of aggravation in absence from training and in the intensity of pain of athletes. 16 goalkeepers were randomly divided into two groups of equal number(study-control). Players completed a specific questionnaire and underwent a procedure where they had to evaluate the intensity of pain as well as being subjected to various measurements. The study group followed a three-month program of muscular strenghtening. On the completion of the program the initial procedures were repeated for both groups. After another three months the subjective sense of aggravation the absence from training and the intensity of pain were recorded for both groups. The players who participated in the program had a statistically decrease in both the intensity of pain and in the absence from training(p<0.05). In addition there was a tendency for the subjective sense of aggravation to be reduced which however was not statistically significant. In conclusion the specific program can be used as a measure for the prevention and management of the syndrome

description: We study the elastic properties and mechanical stability of viral capsids under external force-loading with computer simulations. Our approach allows the implementation of specific geometries corresponding to specific phages such as $ϕ$29 and CCMV. We demonstrate how in a combined numerical and experimental approach the elastic parameters can be determined with high precision. The experimentally observed bimodality of elastic spring constants is shown to be of geometrical origin, namely the presence of pentavalent units in the viral shell. A criterion for capsid breakage is defined, which explains well the experimentally observed rupture. From our numerics we find for the dependence of the rupture force on the Föppl-von Kármán (FvK) number a crossover from $γ^{2/3}$ to $γ^{1/2}$. For filled capsids high internal pressures lead to a stronger destabilization of viruses with a buckled ground state than unbuckled ones. Finally, we show how our numerically calculated energy maps can be used to extract information about the strength of protein-protein interactions from rupture experiments.
