Abstract

The use of transparent test/source masses can benefit future measurements of Newton's gravitational constant $G$. Such transparent test mass materials can enable nondestructive, quantitative internal density gradient measurements using optical interferometry and allow in-situ optical metrology methods to be realized for the critical distance measurements often needed in a $G$ apparatus. To confirm the sensitivity of such optical interferometry measurements to internal density gradients it is desirable to conduct a check with a totally independent technique. We present an upper bound on possible internal density gradients in lead tungstate (PbWO$_4$) crystals using a Talbot-Lau neutron interferometer on the Cold Neutron Imaging Facility (CNIF) at NIST. We placed an upper bound on a fractional atomic density gradient in two PbWO$_{4}$ test crystals of ${1 \over N}{dN \over dx}<0.5 \times 10^{-6}$ cm$^{-1}$. This value is about two orders of magnitude smaller than required for $G$ measurements. We discuss the implications of this result and of other nondestructive methods for characterization of internal density inhomogeneties which can be applied to test masses in $G$ experiments., Comment: 10 pages, 8 figures, submitted to Classical and Quantum Gravity

Abstract

A major step towards the understanding of intrinsic properties of nano-objects depends on the ability to obtain assemblies of nanoparticles of a given size with reduced size dispersion and a well defined shape. The control of these parameters is a fundamental challenge. In this newsletter, we present a new method to tailor in an easy way both size and shape characteristics of nanoparticles by using laser irradiation in the nanosecond regime., Comment: 1 page, 1 figure

The objective of this retrospective observational study was to study the long-term outcome of exercise capacity and quality of life during management of patients with COPD treated by home-based PR.Methods: Home-based PR was administered to 211 patients with COPD (mean age, 62.3±11.1 years; mean forced expiratory volume in 1 second, 41.5%±17.7%). Home-based PR was chosen because of the distance of the patient’s home from the PR center and the patient’s preference. Each patient was individually managed by a team member once a week for 8 weeks with unsupervised continuation of physical exercises on the other days of the week according to an individual action plan. Exercise conditioning, therapeutic patient education, and self-management were included in the PR program. The home assessment comprised evaluation of the patient’s exercise capacity by a 6-minute stepper test, Timed Up and Go test, ten times sit-to-stand test, Hospital Anxiety and Depression score, and quality of life (Visual Simplified Respiratory Questionnaire, VQ11, Maugeri Respiratory Failure 28).Results: No incidents or accidents were observed during the course of home-based PR. The 6-minute stepper test was significantly improved after completion of the program, at 6 months and 12 months, whereas the Timed Up and Go and ten times sit-to-stand test were improved after PR and at 6 months but not at 12 months. Hospital Anxiety and Depression and quality of life scores improved after PR, and this improvement persisted at 6 months and 12 months.Conclusion: Home-based PR for unselected patients with COPD is effective in the short term, and this effectiveness is maintained in the medium term (6 months) and long term (12 months). Home-based PR is an alternative to outpatient management provided all activities, such as exercise conditioning, therapeutic education, and self-management are performed.

Abstract

The Localized Surface Plasmon resonance (LSPR) of metallic nanoparticles (NPs) is strongly dependent on their local environment and on their constituent-material dielectric functions. Thus, chemical modifications occurring at their vicinity, or directly within the NPs may be optically monitored. Moreover, Ag-based NPs may display a well-defined LSPR strongly sensitive to small variations of the surrounding. In this respect, Ag-based NPs (produced by laser vaporization) containing another reactive metal have been investigated. The first illustration deals with iron-silver NPs investigated through TEM observations, in situ optical spectroscopy and Monte Carlo simulations, leading us to conclude that iron and silver initially adopt a segregated configuration with a silver-enriched surface. During oxidation, iron likely diffuses throughout the silver shell, leading to an Ag@Fe3O4 configuration, while an inverse process may occur during annealing under a reducing atmosphere [1].We also performed optical and environmental TEM characterizations on In-Ag NPs. Optical spectra show LSPRs in the UV range down to 310 nm for as prepared NPs. A NP deposition at elevated temperatures even results in an LSPR

Abstract

International audience; Objectives Data are scarce regarding the potential clinical differences between non-late onset schizophrenia (NLOS, i.e., disorder occurring before 40 years of age), late-onset schizophrenia (LOS, occurring between ages 40 and 60 years) and very-late-onset schizophrenia-like psychosis (VLOSLP, occurring after 60 years of age). Furthermore, previous research compared LOS patients with non-age matched NLOS patients. In this study, we sought to examine potential clinical differences between patients of similar age with LOS and NLOS. Methods/Design This is a cross-sectional multicentre study that recruited in- and outpatients older adults (aged >= 55 years) with an ICD-10 diagnosis of schizophrenia or schizoaffective disorder with NLOS and LOS. Sociodemographic and clinical characteristics, comorbidity, psychotropic medications, quality of life, functioning, and mental health care utilization were drawn for comparison. Results Two hundred seventy-two participants (79.8%) had NLOS, 61 (17.9%) LOS, and 8 (2.3%) VLOSLP. LOS was significantly and independently associated with greater severity of emotional withdrawal and lower severity of depression (all p < 0.05). However, the magnitude of these associations was modest, with significant adjusted odds ratios ranging from 0.71 to 1.24, and there were no significant between-group differences in other characteristics. Conclusion In an age-matched multicenter sample of elderly patients with schizophrenia, older adults with LOS were largely similar to older adults with NLOS in terms of clinical characteristics. The few differences observed may be at least partially related to symptom fluctuation with time. Implications of these findings for pharmacological and nonpharmacological management is yet to be determined.

Abstract

The severity of psychopathology has a strong negative impact on quality of life (QoL) among older adults with schizophrenia spectrum disorder. However, because these subjects generally experience multiple psychiatric symptoms, it remains unclear whether decreased QoL in this population is due to specific symptoms (e.g., hallucinations), specific dimensions of psychopathology (e.g., negative symptoms), a general psychopathology dimension representing the shared effect across all psychiatric symptoms, or a combination of these explanations. Data were derived from the Cohort of individuals with Schizophrenia Aged 55 years or more (CSA) study, a large (N = 353) multicenter sample of older adults with schizophrenia spectrum disorder recruited from French public-sector psychiatric departments. We used structural equation modeling to examine the shared and specific effects of psychiatric symptoms on QoL, while adjusting for sociodemographic characteristics, general medical conditions, global cognitive functioning and psychotropic medications. Psychiatric symptoms and QoL were assessed face-to-face by psychiatrists using the Brief Psychiatric Rating Scale (BPRS) and the Quality of Life Scale (QLS). Among older adults with schizophrenia spectrum disorder, effects of psychiatric symptoms on QoL were exerted mostly through a general psychopathology dimension (β = − 0.43, p

Abstract

© 2018 Elsevier Inc. Objective: To determine the percentage of children with nonalcoholic fatty liver disease (NAFLD) in whom intervention for low-density lipoprotein cholesterol or triglycerides was indicated based on National Heart, Lung, and Blood Institute guidelines. Study design: This multicenter, longitudinal cohort study included children with NAFLD enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Nonalcoholic Steatohepatitis Clinical Research Network. Fasting lipid profiles were obtained at diagnosis. Standardized dietary recommendations were provided. After 1 year, lipid profiles were repeated and interpreted according to National Heart, Lung, and Blood Institute Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction. Main outcomes were meeting criteria for clinically actionable dyslipidemia at baseline, and either achieving lipid goal at follow-up or meeting criteria for ongoing intervention. Results: There were 585 participants, with a mean age of 12.8 years. The prevalence of children warranting intervention for low-density lipoprotein cholesterol at baseline was 14%. After 1 year of recommended dietary changes, 51% achieved goal low-density lipoprotein cholesterol, 27% qualified for enhanced dietary and lifestyle modifications, and 22% met criteria for pharmacologic intervention. Elevated triglycerides were more prevalent, with 51% meeting criteria for intervention. At 1 year, 25% achieved goal triglycerides with diet and lifestyle changes, 38% met criteria for advanced dietary modifications, and 37% qualified for antihyperlipidemic medications. Conclusions: More than one-half of children with NAFLD met intervention thresholds for dyslipidemia. Based on the burden of clinically relevant dyslipidemia, lipid screening in children with NAFLD is warranted. Clinicians caring for children with NAFLD should be familiar with lipid management.

Abstract

© 2018 AGA Institute Background & Aims: Focal zone 1 steatosis, although rare in adults with nonalcoholic fatty liver disease (NAFLD), does occur in children with NAFLD. We investigated whether focal zone 1 steatosis and focal zone 3 steatosis are distinct subphenotypes of pediatric NAFLD. We aimed to determine associations between the zonality of steatosis and demographic, clinical, and histologic features in children with NAFLD. Methods: We performed a cross-sectional study of baseline data from 813 children (age

Abstract

A methodology for determining the temperature dependence of Young’s modulus and Poisson’s ratio of polymer foams core materials is presented. The design of the test specimen is described in detail, covering the parasitic effects resulting from departures from the uniform strain condition. The measurement approach is based on a non-contact technique so that the behaviour of the complaint foam is not modified by the attachment of strain gauges or extensometers. Firstly experiments are conducted at room temperature and then at elevated temperatures in a thermal chamber. Readings are taken through an optical window using a standard digital camera. Digital image correlation is used to obtain the strains.
