Positive Effects of a Short-Term Dog-Assisted Intervention for Soldiers With Post-traumatic Stress Disorder—A Pilot Study

Post-traumatic stress disorder (PTSD) is diagnosed in 3% of German and 14–16% of US military following deployment abroad. The treatment of PTSD in soldiers is often challenging and thus new, additional interventions supporting traditional trauma therapy are employed, like animal-assisted interventions (AAI). In this pilot study, 29 soldiers with PTSD received four sessions of 3 h once a week of dog-assisted intervention in addition to inpatient standard treatment at the military hospital, while the control group of 31 soldiers with PTSD received standard treatment only. The dog-assisted intervention sessions included a walk, different play and grooming activities and just relaxing together toward the end. What was new in our approach was that the AAI sessions were delivered by military personnel, military dog-handlers with their own dogs (either military or privately owned). Data on psychiatric symptoms, perceived stress, work and social life, and the therapeutic relationship were answered before the first AAI session, during the days following the last AAI session, 1 month later, and 3 months later. Only the intervention group also answered a questionnaire on trauma confrontation, consumption of alcohol/drugs, mental wellness, and perceived stress each week during intervention. Analyses showed a trend for worse values in work and social adjustment in the control group and a significant trend toward better values in the intervention group. On the other parameters differences between control and intervention group were not significant. The mental wellness of the intervention group improved over the 4 weeks of therapy, particularly regarding the ability to experience joy. There was no clear trend for perceived stress, but the relationship to the dog handler improved significantly over the course of the intervention. This is noteworthy in patients with PTSD who usually have difficulties trusting others, especially new people. Keeping in mind that the AAI took place only four times, our findings point toward the value of dog-assisted interventions. With a longer treatment period the positive effects and trends might become more distinct.
On the Expressive Power of Deep Diagonal Circulant Neural Networks

In this paper, we study deep diagonal circulant neural networks, that is deep neural networks in which all weight matrices are the product of diagonal and circulant ones. We show that these networks outperform the recently introduced deep networks with other types of structured layers. Besides introducing principled techniques for training these models, we provide theoretical guarantees regarding their expressivity. Indeed, we prove that the function space spanned by diagonal circulant networks of bounded depth includes the one spanned by dense networks with specific properties on their rank. We conduct a thorough experimental study to compare the performance of deep diagonal circulant networks with state of the art models based on structured matrices and with dense models. We show that our models achieve better accuracy than their structured alternatives while required 2x fewer weights as the next best approach. Finally we train deep diagonal circulant networks to build a compact and accurate models on a real world video classification dataset with over 3.8 million training examples.
Amplification of the CD24 Gene Is an Independent Predictor for Poor Prognosis of Breast Cancer

CD24 is a glycosyl-phosphatidyl-inositol linked glycoprotein expressed in a broad range of cell types including cancer cells. Although it is overexpressed in nearly 70% of human cancers, copy number variation of the CD24 locus has not been reported for any cancer. Here, we analyzed the genomics, transcriptomics, and clinical data of 1082 breast cancer (BRCA) samples and other cancer samples from the clinically annotated genomic database, The Cancer Genome Atlas (TCGA). The GISTIC2 method was applied to stratify the CD24 copy number, and Cox regression was performed to compare hazard ratio (HR) of CD24 overexpression, amplification and other traditional prognosis features for overall survival (OS). Our data demonstrated that CD24 amplification strongly correlated with its mRNA overexpression as well as TP53 mutant, cancer proliferation and metastasis features. In particular, CD24 amplification was enriched in basal-like subtype samples and associated with poor clinical outcome. Surprisingly, based on the univariate Cox regression analysis, CD24 overexpression (HR = 1.62, P = 0.010) and copy number amplification (HR = 1.79, P = 0.022) was more relevant to OS than TP53 mutant, mutation counts, diagnosis age, and BRCA subtypes. And based on multivariate survival analysis, CD24 amplification remained the most significant and independent predictor for worse OS (HR = 1.88, P = 0.015).
Motor Imagery of Speech: The Involvement of Primary Motor Cortex in Manual and Articulatory Motor Imagery

Motor imagery refers to the phenomenon of imagining performing an action without action execution. Motor imagery and motor execution are assumed to share a similar underlying neural system that involves primary motor cortex (M1). Previous studies have focused on motor imagery of manual actions, but articulatory motor imagery has not been investigated. In this study, transcranial magnetic stimulation (TMS) was used to elicit motor-evoked potentials (MEPs) from the articulatory muscles [orbicularis oris (OO)] as well as from hand muscles [first dorsal interosseous (FDI)]. Twenty participants were asked to execute or imagine performing a simple squeezing task involving a pair of tweezers, which was comparable across both effectors. MEPs were elicited at six time points (50, 150, 250, 350, 450, 550 ms post-stimulus) to track the time course of M1 involvement in both lip and hand tasks. The results showed increased MEP amplitudes for action execution compared to rest for both effectors at time points 350, 450 and 550 ms, but we found no evidence of increased cortical activation for motor imagery. The results indicate that motor imagery does not involve M1 for simple tasks for manual or articulatory muscles. The results have implications for models of mental imagery of simple articulatory gestures, in that no evidence is found for somatotopic activation of lip muscles in sub-phonemic contexts during motor imagery of such tasks, suggesting that motor simulation of relatively simple actions does not involve M1.
Comparative Susceptibility Study Against Pathogens Using Fermented Cranberry Juice and Antibiotics

In the present study, unfermented and fermented cranberry juice in combination with the Antibiotics vancomycin and tigecycline were tested for their antimicrobial activity. Cranberry juice was fermented with a recently isolated potentially probiotic Lactobacillus paracasei K5. The tested strains selected for this purpose were Enterococcus faecalis, E. faecium, Enterobacter cloacae and Staphylococcus aureus. The methods followed were the determination of zones inhibition, Minimum Inhibitory Concentration (MIC) and Fractional Inhibitory Concentration Index (FICI). Tigecycline together with fermented juice exhibited larger Zones of Inhibition (ZOI) in strains of E. faecium (65 ± 4.8 mm) compared to the respective ZOI with tigecycline and unfermented juice (no zone). The same outcome was also obtained with E. cloacae. Vancomycin together with fermented juice exhibited larger ZOI in strains of E. faecium (28 ± 2.2 mm) compared to the respective ZOI with vancomycin and unfermented juice (24 ± 2.3 mm). The lowest MIC values were recorded when tigecycline was combined with fermented cranberry juice against S. aureus strains, followed by the same combination of juice and antibiotic against E. cloacae strains. FICI revealed synergistic effects between fermented juice and tigecycline against a strain of E. faecium (A2020) and a strain of E. faecalis (A1940). Such effects were also observed in the case of fermented juice in combination with vancomycin against a strain of S. aureus (S18), as well as between fermented juice and tigecycline against E. cloacae (E1005 and E1007) strains. The results indicate that the antibacterial activity of juice fermented with the potentially probiotic L. paracasei K5 may be due to synergistic effects between some end fermentation products and the antibiotic agents examined.
Expanders, exact crossed products, and the Baum–Connes conjecture

We reformulate the Baum-Connes conjecture with coefficients by introducing a new crossed product functor for C*-algebras. All confirming examples for the original Baum-Connes conjecture remain confirming examples for the reformulated conjecture, and at present there are no known counterexamples to the reformulated conjecture. Moreover, some of the known expander-based counterexamples to the original Baum-Connes conjecture become confirming examples for our reformulated conjecture.

The Effects of Technology Shocks on Hours and Output: A Robustness Analysis

We analyze the effects of neutral and investment-specific technology shocks on hours and output. Long cycles in hours are captured in a variety of ways. Hours robustly fall in response to neutral shocks and robustly increase in response to investment specific shocks. The percentage of the variance of hours (output) explained by neutral shocks is small (large); the opposite is true for investment specific shocks. `News shocks' that generically change expectations about future productivity, are uncorrelated with the estimated technology shocks.
Sex Differences in Mental Rotation Strategyl2

SztnZJ1ZaJ}'. -\'V'hen humans decide whether two visual stimuli are identical or mirror images of each other and one of the stimuli is rotated with respect to the other, the time discrimination takes usually increases as a rectilinear function of the orientation disparity. On the average, males perform this mental rotation at a faster angular speed than females. This experiment required the rotation of both mirror-image-different and non-mirror-different stimuli. The polygonal stimuli were presented in either spatially unfiltered, high-pass or low-pass filtered versions. All stimulus conditions produced mental rotation-type effects but with graded curvilinear trends. Women rotated faster than men under all conditions, an infrequent outcome in mental rotation studies. Overall, women yielded more convexly curvilinear response functions than men. For both sexes the curvilinearity was more pronounced under the non-mirrordifferent, low-pass stimulus condition than under the mirror different, high-pass stimulus condition. The results are considered as supporting the occurrence of two different mental rotation strategies and as suggesting that the women were predisposed to use efficiently an analytic feature rotation strategy, while the men were predisposed to employ efficiently a holistic pattern rotation strategy. It is argued that the overall design of this experiment promoted the application of an analytic strategy and thus conferred an advantage to the female participants.
POLYNOMIAL REPRESENTATIONS FOR n-TH ROOTS IN FINITE FIELDS

Computing square, cube and n-th roots in general, in finite fields, are important computational problems with significant applications to cryptography. One interesting approach to computational problems is by using polynomial representations. Agou, Deléglise and Nicolas proved results concerning the lower bounds for the length of polynomials representing square roots modulo a prime p. We generalize the results by considering n-th roots over finite fields for arbitrary n > 2.
A Brief Report on Voice Mismatch Effects in Verb Phrase Ellipsis and Sluicing *

The research reported here is part of a larger project investigating similarities and differences among varieties of ellipsis constructions, including VP ellipsis, Sluicing, Pseudogapping, Gapping and NP ellipsis. Merchant (2008), and more recently Tanaka (2011), have claimed that while VP ellipsis (VPE) can tolerate a mismatch in voice between antecedent and ellipsis site, Pseudogapping and Sluicing cannot. Merchant derives this from the claim that the [VOICE] feature is within the Pseudogapping and Sluicing ellipsis sites but is above the VPE ellipsis site, so the value of [VOICE] is relevant to the former but not the latter. We present the results of a Magnitude Estimation experiment (Bard et al., 1996) examining this prediction in VP Ellipsis (1) and Sluicing (2).
International Journal of C 2009 Institute for Scientific Numerical Analysis and Modeling Computing and Information Well Flow Models for Various Numerical Methods

Numerical simulation of fluid flow and transport processes in the subsurface must account for the presence of wells. The pressure at a gridblock that contains a well is different from the average pressure in that block and different from the flowing bottom hole pressure for the well [17]. Various finite difference well models have been developed to account for the difference. This paper presents a systematical derivation of well models for other numerical methods such as standard finite element, control volume finite element, and mixed finite element methods. Numerical results for a simple well example illustrating local grid refinement effects are given to validate these well models. The well models have particular applications to groundwater hydrology and petroleum reservoirs.
Rehydration of Zn-a1 Layered Double Hydroxides

Rehydration is shown to be straightforward for the reconstruction of polyoxometallate-pillared layered double hydroxides. Zn-A1 hydrotalcite-like minerals were prepared with Zn/A1 ratios of 1 to 5 by coprecipitation at pH 7. Good crystallinity was obtained for samples with Zn/Al ratios above 2. Thermal decomposition was achieved by calcining the samples at 300 to 900 ~ The calcined samples were exposed to decarbonated water, with or without hydrothermal treatment to evaluate reconstruction of the hydrotalcite-like minerals by rehydration. Restoration of the hydrotalcite-like structure was found to be independent of the Zn/A1 ratios for samples calcined between 300 and 400 ~ however, a second phase, aluminum hydroxide or zinc oxide, was generally detected. A spinel phase, formed during the calcination of samples at temperatures above 600 ~ inhibited reconstruction of the hydrotalcite-like phase. The rehydrated hydrotalcite-like minerals had Zn/A1 ratios close to 2, irrespective of the chemistry of the starting material.
Nonstandard Lorentz space forms

In their recent paper [8], Kulharni and Raymond show that a closed 3-manifold which admits a complete Lorentz metric of constant curvature 1 (henceforth called a complete Lorentz structure) must be Seifert fibered over a hyperbolic base. Furthermore on every such Seifert fibered 3-manifold with nonzero Euler class they construct such a Lorentz metric. Moreover the Lorentz structure they construct has a rather strong additional property, which they call "standard": A Lorentz structure is standard if its causal double cover possesses a timelike Killing vector field. Equivalently, it possesses a Riemannian metric locally isometric to a left-invariant metric on SL(2, R). Kulkarni and Raymond asked if every closed 3-dimensional Lorentz structure is standard. This paper provides a negative answer to this question (Theorem 1) and a positive answer to the implicit question raised in [8, 7.1. 1] (Theorem 3). Theorem 1. Let M3 be a closed 3-manifold which admits a homogeneous Lorentz structure and satisfies Hι{M\ R) Φ 0. Then there exists a nonstandard complete Lorentz structure on M. In [8] it is shown that the unit tangent bundle of a closed surface admits a homogeneous Lorentz structure. Therefore we obtain: Corollary 2. There exists a complete Lorentz structure on the unit tangent bundle of any closed surface F of genus greater than one which is not standard. The homogeneous Lorentz structures are all classified in [8]. A circle bundle of Euler number j over a closed surface F, χ(F) < 0, has a homogeneous structure if and only if j\χ(F) (an analogous statement holds when M has singular fibers, i.e. when F is an orbifold). We also show: Theorem 3. Let M3 be a 3-manifold which admits a complete Lorentz structure. Then M3 is not covered by a product F X Sι, Fa closed surface. Theorem 3 implies that the Euler class of the Seifert fiber structure of M3 is nonzero.
A modified Galerkin/finite element method for the numerical solution of the Serre‐Green‐Naghdi system

A new modified Galerkin/finite element method is proposed for the numerical solution of the fully nonlinear shallow water wave equations. The new numerical method allows the use of low‐order Lagrange finite element spaces, despite the fact that the system contains third order spatial partial derivatives for the depth averaged velocity of the fluid. After studying the efficacy and the conservation properties of the new numerical method, we proceed with the validation of the new numerical model and boundary conditions by comparing the numerical solutions with laboratory experiments and with available theoretical asymptotic results.

An experimental study of workflow and collaborative document authoring in medical research

Workflow is asynchronous technology widely used in the automation of organisational processes. Workflow provides benefits such as greater eflciency in an organisation, better worker productivity and greater process control. Synchronous collaborative authoring tools are technologies that allow a group of dispersed authors to write a document at the same time. These tools are beneficial in assisting authors to write some proportion, if not all, of a document simultaneously. This paper presents findings from an experiment combining both workflow and collaborative authoring tools in a medical research environment. Studies investigating the combination of these tools are few, resulting in a lack of understanding of how this combination can effectively assist organisations in document-based processes. Overall, the combined workflow/collaborative authoring solution was found effective in the generation of a medical research paper.
NEUTRON ACTIVATION ANALYSIS OF MANGANESE, IRON AND ZINC IN A RODENT MODEL OF DYSMYELINATION

Transition metals have been suggested to play a pivotal role in the pathogenesis of numerous neurological disorders. They serve critical roles in the central nervous system (CNS) as essential cofactors, catalysts, secondary messengers and modulators of genes, enzymes and receptor activity. Manganese (Mn), iron (Fe) and zinc (Zn) are some of the essential metals for normal CNS development and function. Each must be present at specific levels to avoid deficiencies or toxic excess. The research in this thesis investigates the role of transition metals in diseases in which myelin is lost in the central nervous system (CNS). A loss of myelin is termed demyelination, and an example of a disease with prominent demyelination is multiple sclerosis. An incomplete formation of myelin sheaths is termed dysmyelination. This thesis focused on the measurements of manganese, iron and zinc concentrations in a rodent model of dysmyelination; the Long Evans Shaker (les) rat. The Long Evans Shaker (les) rat is a fragile, severely dysmyelinated rodent model with body tremors at a young age and severe ataxia in older rats. The mutation causing the severe dysmyelination in these rats is transmitted as an autosomal recessive trait. With a lifespan of 4 to 5 months, the les rat is markedly deficient in myelin in the CNS, where most axons are entirely naked and the remaining ones are surrounded by a loosely woven, thin myelin sheath. In this thesis we studied alterations in manganese, iron and zinc transition metal levels in 3 and 16-week-old les rats and their age-matched control counterparts. Using neutron activation analysis (NAA), manganese measurements were made in the brain, spinal cord and visceral organs using an existing protocol, while a new assay was developed for iron and zinc measurements that were made in the spinal cord tissues. The higher trend in manganese concentration observed within the 3 and 16 week old les rats in comparison to the controls, where there was a significant increase (p<0.05) observed in the 16 week old les cerebellum, supports evidence suggesting that manganese levels are associated with astrogliosis. Whereas for iron and zinc, which were measured in the spinal cord tissues, there was also an overall increase in the levels of these metals in the les mutant strain when compared to the controls; however, only significant increases in zinc concentration within the 16 week old les spinal cords were observed. The overall trend in increased iron in the …

Les chauffeurs du dimanche : un examen empirique des effets des stéréotypes négatifs sur les réactions au volant des conducteurs âgés en contexte de simulation

This thesis wished to investigate the existence of stereotypes pertaining to older drivers (Experiment 1 and 2) and their influence on the simulated driving performance of older adults (Experiment 3). In Experiments 1 and 2, participants viewed 12 clips of driving reactions created using a driving simulator (i.e., four clips of older drivers‘ unsafe behaviours, four clips of younger adults‘ unsafe behaviours, and four clips of appropriate driving behaviours). In Experiment 1, 61 participants rated how representative the behaviours were of a typical younger, middle-aged or older driver. Older drivers‘ unsafe behaviours were rated as more representative of the older driver, while young adults‘ unsafe behaviours were perceived as more representative of the younger driver than the other two age groups. Appropriate driving behaviours were rated as more representative of the middle-aged driver than the young and older driver. Consequently, older drivers‘ stereotypes include specific unsafe behaviours and seem to be predominantly negative. In Experiment 2, 68 participants indicated whether the observed behaviours were representative or not of the typical older driver and answered an open-ended question in regards to the main features associated to the older driver. Older drivers‘ unsafe behaviours were deemed more representative of the older driver, than younger drivers‘ unsafe behaviours. Appropriate driving behaviours were also found to be representative of the typical older driver. These results reveal that while negative features are mainly linked to the older drivers, positive aspects are also present. In Experiment 3, 61 older drivers aged 65 years and above completed a simulated driving task, either under Stereotype Threat (i.e., objective of the study explicitly stated that they were overrepresented in statistics pertaining to on-road accidents) or not (neutral objective). Participants in the Stereotype Threat condition who
