description: In this summary of the application of Dyson-Schwinger equations to the theory and phenomenology of hadrons, some deductions following from a nonperturbative, symmetry-preserving truncation are highlighted, notable amongst which are results for pseudoscalar mesons. We also describe inferences from the gap equation relating to the radius of convergence of a chiral expansion, applications to heavy-light and heavy-heavy mesons, and quantitative estimates of the contribution of quark orbital angular momentum in pseudoscalar mesons; and recapitulate upon studies of nucleon electromagnetic form factors.

description: Molecular Dynamics simulations of crystallization in a supercooled liquid of Lennard-Jones particles with different range of attractions shows that the inclusion of the attractive forces from the first, second and third coordination shell increases the trend to crystallize systematic. The bond-order $Q_6$ in the supercooled liquid is heterogeneously distributed with clusters of particles with relative high bond-order for a supercooled liquid, and a systematic increase of the extent of heterogeneity with increasing range of attractions. The onset of crystallization appears in such a cluster, which together explains the attractive forces influence on crystallization. The mean square displacement and self-diffusion constant exhibit the same dependence on the range of attractions in the dynamics and shows, that the attractive forces and the range of the forces plays an important role for bond-ordering, diffusion and for crystallization.

description: Extensive excavations at the Late Neolithic settlement of Makriyalos in North Greece recovered various contexts of food preparation and consumption, providing a unique opportunity to investigate social interaction through food consumption in the LN community. The investigation focuses on the social context of food preparation and consumption, contrasting the daily household level of consumption with that in community (feasting) context, through study of the morphological, technological and stylistic variability of ceramic vessels, examination of their spatial distribution and chemical analysis of associated organic remains. Evidence for the diet of the inhabitants of Makriyalos, derived from macroscopic analysis of food remains and the study of human bones is also considered. The results of pottery study combined with biochemical analysis indicate considerable differences within the community in food behaviour, suggesting a complex picture concerning social identities of the Makriyalos inhabitants. An active negotiation between individuals and community was at play in Makriyalos, indicating that social differentiation in the Neolithic society may have been expressed in more subtle ways than the archaeologists usually expect

description: Markov networks are popular models for discrete multivariate systems where the dependence structure of the variables is specified by an undirected graph. To allow for more expressive dependence structures, several generalizations of Markov networks have been proposed. Here we consider the class of contextual Markov networks which takes into account possible context-specific independences among pairs of variables. Structure learning of contextual Markov networks is very challenging due to the extremely large number of possible structures. One of the main challenges has been to design a score, by which a structure can be assessed in terms of model fit related to complexity, without assuming chordality. Here we introduce the marginal pseudo-likelihood as an analytically tractable criterion for general contextual Markov networks. Our criterion is shown to yield a consistent structure estimator. Experiments demonstrate the favorable properties of our method in terms of predictive accuracy of the inferred models.
A neuroanatomical analysis of the distribution of histopathologic lesions in alzheimer's disease
Creators: name: Beach, Thomas Gerald
Publisher: name: University of British Columbia
Year: 2011

description: The thesis was designed to address two major questions about the pathogenesis of Alzheimer's disease. These are: one, does Alzheimer's disease "spread" throughout the brain along neuroanatomical pathways? And two, can the histopathological lesions of Alzheimer's disease be the result of degeneration of a single neuronal system? The investigation began by comparing the pattern of cerebral gliosis in Alzheimer's disease (AD) with that seen in normal aging. This was done using an immunoperoxidase stain for glial fibrillary acidic protein (GFAP) to reveal astrocytic gliosis within whole-hemisphere sections. Gliosis was most severe, and most consistently seen, in the cerebral cortex and hippocampus. Subcortical nuclei were inconsistently affected. Within the cortex, the laminae which are most severely affected are II, III and V. Distinct bands of gliosis were present in these laminae in at least some cortical areas in every AD brain. The pattern of gliosis within area 17, the primary visual area, was anomalous in that there was the a thin band of gliosis at the border between layers IVc and V. This was matched by a line of senile plaques at the same site, revealed using an enhanced Bielschowsky stain. Such a precise disposition implies a neuronal origin for these plaques, but there is no known afferent system which is concentrated along this line. Specific afferent systems to layers IVc and V of area 17 were then examined histologically for evidence of morphological relationships to senile plaques. Only cholinergic elements were in obvious relation to senile plaques; in addition, only cholinergic elements showed evidence of depletion and morphological abnormality. In the last part of the thesis, the distribution of amyloid ß-protein (AßP) in area 17 was studied using an immunoperoxidase method. This was found to differ substantially from the distribution of senile plaques, with obvious bands of dense staining in layers I and IVc, layers that did not possess significantly larger numbers of plaques as seen with the enhanced Bielschowsky method. Acetylcholinesterase-positive fibres within area 17 were co-distributed with AßP to layers I and IVc, providing further evidence that amyloid may be formed at cholinergic fibres. The results of this thesis are most compatible with the hypothesis that Alzheimer's disease represents a primary degeneration of the cholinergic system of the nucleus basalis of Meynert. A review of the literature suggests that current opinion relegating the cholinergic degeneration to a secondary role is not adequately substantiated.

description: We investigate the structural, electronic and magnetic properties of the full Heusler compounds Mn$_2$YSn (Y = Mo, Nb, Zr) by first-principles density functional theory using the generalized gradient approximation. It is found that the calculated lattice constants are in good agreement with the theoretical values. We observe that the Cu$_2$MnAl-type structure is more stable than the Hg$_2$CuTi type. The calculated total magnetic moments of Mn$_2$NbSn and Mn$_2$ZrSn are 1 $μ_{\text{B}}$ and 2 $μ_{\text{B}}$ at the equilibrium lattice constant of 6.18 Åand 6.31 Å, respectively, for the Cu$_2$MnAl-type structure. Mn$_2$MoSn have a metallic character in both Hg$_2$CuTi and Cu$_2$MnAl type structures. The total spin magnetic moment obeys the Slater-Pauling rule. Half-metal exhibits 100% spin polarization at the Fermi level. Thus, these alloys are promising magnetic candidates in spintronic devices.

Bimodal Infrared Colors of the M87 Globular Cluster System: Peaks in the Metallicity Distribution

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: The globular cluster (GC) systems of many galaxies reveal bimodal optical color distributions. Based on stellar evolutionary models and the bimodal colors and metallicities of Galactic GCs this is thought to reflect an underlying bimodal metallicity distribution. However, stars at many different phases of stellar evolution contribute to optical light. The I-H color is a much cleaner tracer of metallicity because it primarily samples the metallicity sensitive giant branch. Therefore, we use deep HST-NICMOS H, and WFPC2 optical observations, of M87 GCs to study their metallicity distribution. The M87 clusters are bimodal in I-H, for which there is no known physical explanation other than a bimodal metallicity distribution. Moreover, the two modes defined by the B-I and I-H colors are comprised of roughly the same two sets of objects, confirming that optical colors also primarily trace the metallicity. This is inconsistent with a recent suggestion based on one model of metallicity effects on the horizontal branch that bimodality arises from an underlying unimodal metallicity distribution due to a specific color-metallicity relation. We also find no discernable variation in the peak colors of the M87 GCs out to roughly 75 kpc due to the declining ratio of red-to-blue GCs, as implied by this model. Similarly, there is no evidence that the bimodal peaks are bluer for systems with large blue-to-red GC ratio. Our observations confirm that the primary cause of bimodality in cluster systems is an underlying bimodal metallicity distribution, and not the specific color-metallicity relationship defined by this horizontal branch model.

description: Ransomware is a malicious class of software that utilises encryption to implement an attack on system availability. The target's data remains encrypted and is held captive by the attacker until a ransom demand is met. A common approach used by many crypto-ransomware detection techniques is to monitor file system activity and attempt to identify encrypted files being written to disk, often using a file's entropy as an indicator of encryption. However, often in the description of these techniques, little or no discussion is made as to why a particular entropy calculation technique is selected or any justification given as to why one technique is selected over the alternatives. The Shannon method of entropy calculation is the most commonly-used technique when it comes to file encryption identification in crypto-ransomware detection techniques. Overall, correctly encrypted data should be indistinguishable from random data, so apart from the standard mathematical entropy calculations such as Chi-Square, Shannon Entropy and Serial Correlation, the test suites used to validate the output from pseudo-random number generators would also be suited to perform this analysis. he hypothesis being that there is a fundamental difference between different entropy methods and that the best methods may be used to better detect ransomware encrypted files. The paper compares the accuracy of 53 distinct tests in being able to differentiate between encrypted data and other file types. The testing is broken down into two phases, the first phase is used to identify potential candidate tests, and a second phase where these candidates are thoroughly evaluated. To ensure that the tests were sufficiently robust, the NapierOne dataset is used. This dataset contains thousands of examples of the most commonly used file types, as well as examples of files that have been encrypted by crypto-ransomware.

description: The bulk polarization is a $\mathbb{Z}_2$ topological invariant characterizing non-interacting systems in one dimension with chiral or particle-hole symmetries. We show that the bulk polarization can always be determined from the single-particle entanglement spectrum, even in the absence of symmetries that quantize it. In the symmetric case, the known relation between the bulk polarization and the number of virtual topological edge modes is recovered. We use the bulk polarization to compute Chern numbers in 1D and 2D, which illuminates their known relation to the entanglement spectrum. Furthermore we discuss an alternative bulk polarization that can carry more information about the surface spectrum than the conventional one and can simplify the calculation of Chern numbers.

description: Background: The frontiers of clinical medicine constantly expand as a result of the innovative efforts of visionary researchers and keen observations of seasoned clinicians. In medicine, rarely has a therapeutic agent been found efficacious in the management of so many symptoms and in such a relatively short time as botulinum toxin. One of the most notable contributions of botulinum toxin therapy in clinical medicine is in the field of movement disorders. Methods: The English literature was searched using the Yale search engine including but not limited to PubMed and Ovid. The search includes articles from January 1 1980 to March 1 2016. Results: A total of 2055 articles were identified. Of these, 132 met the criteria for this review. Discussion: This historical review highlights early and seminal contributions that have introduced the application of botulinum toxins in the field of movement disorders and provides evidence-based contributions that have established botulinum toxin as an effective treatment for abnormal movements.

The physical condition required to satisfy the specific symmetry relation $f^{\rm xc}_{s\bar s}(ζ) = f^{\rm xc}_{\bar s s}(ζ)$ is derived and examined for simple ferromagnetic-nonmagnetic structure by taking the electrochemical potential into account. The condition is then applied to several composite systems useful in spintronics applications such as the magnetic system with net spin polarization.

Electromagnetic polarizabilities of the nucleon and properties of the $σ$-meson pole contribution

Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The $t$-channel contribution to the difference of electromagnetic polarizabilities of the nucleon, $(α-β)^t$, can be quantitatively understood in terms of a $σ$-meson pole in the complex $t$-plane of the invariant scattering amplitude $A_1(s,t)$ with properties of the $σ$ meson as given by the quark-level Nambu--Jona-Lasinio model (NJL). Equivalently, this quantity may be understood in terms of a cut in the complex $t$-plane where the properties of the $σ$ meson are taken from the $ππ-> σ-> ππ$, $γγ-> σ-> ππ$ and $N\bar{N} -> σ-> ππ$ reactions. This equivalence may be understood as a sum rule where the properties of the $σ$ meson as predicted by the NJL model are related to the $f_0(600)$ particle observed in the three reactions. In the following we describe details of the derivation of $(α-β)^t$ making use of predictions of the quark-level NJL model for the $σ$-meson mass.

Orthostatic Tremor and Orthostatic Myoclonus: Weight-bearing Hyperkinetic Disorders: A Systematic Review, New Insights, and Unresolved Questions
Creators: name: Hassan, Anhar
name: Van Gerpen, Jay A
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2016

description: Background: Orthostatic tremor (OT) and orthostatic myoclonus (OM) are weight-bearing hyperkinetic movement disorders most commonly affecting older people that induce “shaky legs” upon standing. OT is divided into “classical” and “slow” forms based on tremor frequency. In this paper, the first joint review of OT and OM, we review the literature and compare and contrast their demographic, clinical, electrophysiological, neuroimaging, pathophysiological, and treatment characteristics. Methods: A PubMed search up to July 2016 using the phrases “orthostatic tremor,” “orthostatic myoclonus,” “shaky legs,” and “shaky legs syndrome” was performed. Results: OT and OM should be suspected in older patients reporting unsteadiness with prolonged standing and/or who exhibit cautious, wide-based gaits. Surface electromyography (SEMG) is necessary to verify the diagnoses. Functional neuroimaging and electrophysiology suggest the generator of classical OT lies within the cerebellothalamocortical network. For OM, and possibly slow OT, the frontal, subcortical cerebrum is the most likely origin. Clonazepam is the most useful medication for classical OT, and levetiracetam for OM, although results are often disappointing. Deep brain stimulation appears promising for classical OT. Rolling walkers reliably improve gait affected by these disorders, as both OT and OM attenuate when weight is transferred from the legs to the arms. Discussion: Orthostatic hyperkinesias are likely underdiagnosed, as SEMG is often unavailable in clinical practice, and thus may be more frequent than currently recognized. The shared weight-bearing induction of OT and OM may indicate a common pathophysiology. Further research, including use of animal models, is necessary to better define the prevalence and pathophysiology of OT and OM, in order to improve their treatment, and provide additional insights into basic balance and gait mechanisms.

description: Reduced forms, such as linking, reduction, and assimilation, are widely used in spoken English and are the main reasons that affect the listening comprehension of learners of English as a Second Language (ESL), as pointed out by many researchers (e.g. Wong et al., 2015; Field, 2003). Shadowing is a listening technique which requires learners to track the heard speech and vocalize it in real time (Tamai, 2002). It reinforces learners’ phonological coding and their speech perception, particularly by training the phonological loop in the working memory (Baddeley, 2007). The primary goal of this study is to investigate the perception of reduced forms through shadowing on improving ESL learners’ listening comprehension.

Αντίθετα, μέσα από την αυτοβιογραφία του ακολουθεί μία αντίστροφη διαδρομή, δεν ενδιαφέρεται για τον ημερολογιακό χρόνο αλλά για τον φυσικό χρόνο ο οποίος βιώνεται ταυτόχρονα με τον βιολογικό. Αποτυπώνει τα στάδια μετάβασης από τον συλλογικό χρόνο του κοινωνικού ανθρώπου- ο οποίος διασπάται ανάμεσα στον ατομικό του χρόνο και τον χρόνο των εξωτερικών κοινωνικών του επαφών-στον προσωπικό του χρόνο, μοναδικό υποκατάστατο ανάμεσα στον φυσικό και πλασματικό χρόνο. Η αποκατάσταση της ενότητας του ατομικού παρελθόντος, παρόντος και μέλλοντος και η επιθυμία του για την αιωνιότητα τον οδηγεί στην κατάργηση του χρόνου
description: Through his political works, Jean-Jacques Rousseau stresses the stages of transition from personal time of primitive man to collective time of man within society. According to the writer, the equation of ideas with attitudes transformed conventional collective time into variable time, so he suggests that customs should be equated for the purposes of establishing collective time, thus transforming it into real time. Through his creative imagination he unites the collective past, present and future : in reference to calendar time he concludes that civil law is the only substitute for natural law. On the contrary, through his autobiography, he follows a reverse course and shows an interest not in calendar time but in physical and spiritual time, which are experienced simultaneously with biological time. He imprints the stages of transition from collective time of social man, which is divided between personal time and time dedicated to external relationships, to personal time, which is the only substitute between physical and fictions time. The restoration of unity among the personal past, prsent and future and his desire for eternity leads him to the abolition of time

description: We report on the direct detection of a close companion to HD 160934, a young active star, SB1 spectroscopic binary, and suggested member of the AB Doradus moving group. High angular resolution at the Calar Alto 2.2m telescope was achieved by means of the Lucky Imaging technique, allowing direct imaging close to the diffraction limit in the SDSS z' band. Our results are combined with pre-discovery HST archive data, own UBVRI broadband photometry, published JHK magnitudes, and available radial velocity measurements to constrain the physical properties of the HD 160934 close binary. We suggest that the direct detection may be identical to the spectroscopically discovered companion.

description: We investigate the cosmological evolution of the system of a Dirac-Born-Infeld field plus a perfect fluid. We analyze the existence and stability of scaling solutions for the AdS throat and the quadratic potential. We find that the scaling solutions exist when the equation of state of the perfect fluid is negative and in the ultra-relativistic limit.

description: For a class of one-dimensional Schrodinger operators with polynomial potentials that includes Hermitian and PT-symmetric operators, we show that the zeros of scaled eigenfunctions have a limit disctibution in the complex plane as the eigenvalues tend to infinity. This limit distribution depends only on the degree of potential and on the boundary conditions.

description: Background: The aim was to compare the occurrence of post-injection dysphagia in parkinsonism-related cervical dystonia (PRCD) versus cervical dystonia (CD) of other etiologies (non-PRCD). A secondary objective was to explore potential clinical differences between PRCD and non-PRCD and their respective responses to botulinum toxin (BoNT). Methods: A cross-sectional chart review was carried out of patients treated for CD with Onabotulinumtoxin A at the University of Florida. We collected demographic information, dose of BoNT injected, patient-reported presence of dysphagia as a side effect, patient-perceived duration of benefit and efficacy according to the Clinical Global Impression Scale (CGIS). Results: Of the 144 patients included, 24 patients were diagnosed with PRCD and 120 were diagnosed as non-PRCD. Data analysis showed no significant differences in number of weeks of benefit from BoNT (PRCD 9.1±3.7 versus non-PRCD 9.4±3.7 weeks, p = 0.830), BoNT dosage (PRCD 235.0±95.6 versus non-PRCD 263.7±101.3 units, p = 0.181), median CGIS score (median = 2 or “much improved” for both groups, p = 0.88), or the presence of dysphagia after BoNT (PRCD 17% versus non-PRCD 19 %, p = 0.753, n = 132). In a subgroup analysis of the non-PRCD group, patients who experienced dysphagia were older than those who did not (63.9±8.9 years versus 58.1±14.4 years, p = 0.02). Discussion: Despite an increased baseline risk of dysphagia in patients with PRCD, BoNT appears to be equally safe and equally beneficial in PRCD and non-PRCD patients.

description: (Abridged) We compared the quantified morphological properties of 37 intermediate redshift MgII absorption selected galaxies to the properties of the absorbing halo gas, observed in the spectra of background quasars. The galaxy morphologies were measured using GIM2D modeling of Hubble Space Telescope WFPC-2 images and the absorbing gas properties were obtained from HIRES/Keck and UVES/VLT quasar spectra. We found a 3.1 sigma correlation between galaxy morphological asymmetries normalized by the quasar-galaxy projected separations, A/D, and the MgII rest-frame equivalent widths. Saturation effects cause increased scatter in the relationship with increasing W_r(2796). We defined a subsample for which the fraction of saturated pixels in the absorption profiles is f_sat<0.5. The correlation strengthened to 3.3 sigma. We also find a paucity of small morphological asymmetries for galaxies selected by MgII absorption as compared to those of the general population of field galaxies, as measured in the Medium Deep Survey. The K-S probability that the two samples are drawn from the same galaxy population is ruled out at a 99.8% confidence level. The A/D-W_r(2796) correlation suggests a connection between the processes that perturb galaxies and the quantity of gas in their halos, normalized by the impact parameter. Since the perturbations are minor, it is clear that dramatic processes or events are not required for a galaxy to have an extended halo; the galaxies appear "normal". We suggest that common, more mild processes that populate halos with gas, such as satellite galaxy merging, accretion of the local cosmic web, and longer-range galaxy-galaxy interactions, consequently also induce the observed minor perturbations in the galaxies.

description: Background: Deutetrabenazine, an inhibitor of vesicular monoamine transporter type 2 (VMAT2) depletes presynaptic dopamine and is useful in the treatment of hyperkinetic movement disorders. This study explored the safety, tolerability, and preliminary efficacy of deutetrabenazine in adolescents with moderate-to-severe tics associated with Tourette syndrome (TS). Methods: In this open-label study of 12–18-year-old patients with TS-related tics, deutetrabenazine was titrated up to 36 mg/day over 6 weeks to adequately suppress tics without bothersome adverse effects (AEs), followed by maintenance at optimal dose for 2 weeks. An independent blinded rater assessed tic severity using the Yale Global Tic Severity Scale (YGTSS), which was the primary outcome measure. Secondary outcome measures included the TS Clinical Global Impression (TS-CGI) and TS Patient Global Impression of Change (TS-PGIC). Results: Twenty-three enrolled patients received deutetrabenazine and had at least 1 post-baseline YGTSS assessment. The mean (SD [standard deviation]) baseline YGTSS Total Tic Severity Score (TTS) was 31.6 (7.9) and had decreased by 11.6 (8.2) points at week 8, a 37.6% reduction in tic severity (p<0.0001). The TS-CGI score improved by 1.2 (0.81) points (p<0.0001) and the TS-PGIC results at week 8 indicated that 76% of patients were much improved or very much improved compared with baseline. The mean (SD) daily deutetrabenazine dose at week 8 was 32.1 (6.6) mg (range 18–36 mg). One week after withdrawal of deutetrabenazine, the TTS scores increased by 5.6 (8.4) points, providing confirmation of the drug effect. No serious or severe adverse events were reported. Discussion: The results of this open-label 8-week study suggest that deutetrabenazine is safe and associated with improvement in tic severity in adolescents with TS and troublesome tics.

description: Surmounting the complexities in analyzing the mechanical parameters of concrete entails selecting an appropriate methodology. This study integrates an artificial neural network (ANN) with a novel metaheuristic technique, namely satin bowerbird optimizer (SBO) for predicting uniaxial compressive strength (UCS) of concrete. For this purpose, the created hybrid is trained and tested using a relatively large dataset collected from the published literature. Three other new algorithms, namely Henry gas solubility optimization (HGSO), sunflower optimization (SFO), and vortex search algorithm (VSA) are also used as benchmarks. After attaining a proper population size for all algorithms, Utilizing various accuracy indicators, it was shown that the proposed ANN-SBO not only can excellently analyze the UCS behavior, but also outperforms all three benchmark hybrids (i.e., ANN-HGSO, ANN-SFO, and ANN-VSA). In the prediction phase, the correlation indices of 0.87394, 0.87936, 0.95329, and 0.95663, as well as mean absolute percentage errors of 15.9719, 15.3845, 9.4970, and 8.0629%, calculated for the ANN-HGSO, ANN-SFO, ANN-VSA, and ANN-SBO, respectively, manifested the best prediction performance for the proposed model. Also, the ANN-VSA achieved reliable results as well. In short, the ANN-SBO can be used by engineers as an efficient non-destructive method for predicting the UCS of concrete.

description: Background: Autosomal dominant congenital mirror movements (CMM) is a neurodevelopmental disorder characterized by early onset involuntary movements of one side of the body that mirror intentional movements on the contralateral side; these persist throughout life in the absence of other neurological symptoms. The main culprit genes responsible for this condition are RAD51 and DCC. This condition has only been reported in a few families, and the molecular mechanisms linking RAD51 mutations and mirror movements (MM) are poorly understood. Methods: We collected demographic, clinical, and genetic data of a new family with CMM due to a truncating mutation of RAD51. We reviewed the literature to identify all reported patients with CMM due to RAD51 mutations. Results: We identified a heterozygous nonsense mutation c.760C>T (p.Arg254∗) in eight subjects: four with obvious and disabling MM, and four with a mild phenotype. Including our new family, we identified 32 patients from 6 families with CMM linked to RAD51 variants. Discussion: Our findings further support the involvement of RAD51 in CMM pathogenesis. Possible molecular mechanisms involved in CMM pathogenesis are discussed.
