The Complex, Unique, and Powerful Imaging Instrument for Dynamics (CUPI2D) at the Spallation Neutron Source (invited).

The Oak Ridge National Laboratory is planning to build the Second Target Station (STS) at the Spallation Neutron Source (SNS). STS will host a suite of novel instruments that complement the First Target Station's beamline capabilities by offering an increased flux for cold neutrons and a broader wavelength bandwidth. A novel neutron imaging beamline, named the Complex, Unique, and Powerful Imaging Instrument for Dynamics (CUPI2D), is among the first eight instruments that will be commissioned at STS as part of the construction project.

Correcting thermal-emission-induced detector saturation in infrared spectroscopy.

We found that temperature-dependent infrared spectroscopy measurements (i.e., reflectance or transmittance) using a Fourier-transform spectrometer can have substantial errors, especially for elevated sample temperatures and collection using an objective lens.

Employment Trends in Rhode Island From 2011 to 2017 for Adults With Intellectual Disability and Developmental Disabilities.

This study reports on state-level data in Rhode Island on employment and non-work activities of adults with intellectual and developmental disabilities receiving services between 2011 and 2017. The goal was to examine the complex patterns of change over time in individual-level employment outcomes and the potential short-term impacts of a consent decree entered into by the state of Rhode Island to address integrated employment outcomes. Findings suggest that policy initiatives such as the consent decree can lead to reductions in reliance on facility-based work, but also highlight the importance of planning for the transition to competitive, integrated employment and not simply a shift toward non-work activities.

Examining the Impact of the SDLMI and Whose Future Is It? Over a Two-Year Period With Students With Intellectual Disability.

The purpose of this study was to examine self-determination outcome data in the year following a one-year cluster randomized controlled trial (C-RCT) comparing the impacts of a Self-Determined Learning Model of Instruction (SDLMI) only condition to a SDLMI + (SDLMI + WF) condition. Using multilevel B-spline model analysis with Bayesian estimation, we examined ongoing patterns of growth after the trial ended and all students were exposed to SDLMI + WF. The findings suggest that the inclusion of an additional year of outcome data provided additional insight into the impact of more intensive intervention conditions over time.

A Review of Driving Restrictions in Patients at Risk of Syncope and Cardiac Arrhythmias Associated with Sudden Incapacity: Differing Global Approaches to Regulation and Risk.

The ability to drive is a highly valued freedom in the developed world. Sudden incapacitation while driving can result in injury or death for the driver and passengers or bystanders. Cardiovascular conditions are a primary cause for sudden incapacitation and regulations have long existed to restrict driving for patients with cardiac conditions at high risk of sudden incapacitation.

Combined subpectoral implantation of a cardioverter defibrillator and breast augmentation surgery in a patient with Emery-Dreifuss muscular dystrophy.

We present the case of a 28-year-old female with Emery-Dreifuss muscular dystrophy and breast hypoplasia, who underwent implantation of a subpectoral defibrillator and bilateral breast augmentation during a single elective procedure at our institution.

Routine issuance of clinical magnets to patients receiving implantable defibrillators: retention of information and appropriateness of use.

Background: The application of a clinical magnet over an implantable cardioverter defibrillator (ICD) can be used to suspend tachycardia therapies in patients receiving recurrent or inappropriate shocks. In our institution, they have been routinely issued to patients undergoing ICD implantation during the past 5 years. The purpose of this survey was to investigate how well information concerning their use had been retained, and in what circumstances the magnets had been used.

Late failure of a single-coil transvenous implantable cardioverter-defibrillator lead associated with conductor separation.

Two patients with the same model of single-coil active fix implantable defibrillator lead presented with evidence of lead malfunction, in one case with an abrupt rise in pacing impedance and threshold and in the other with evidence of over-sensing. In both cases, the chest radiograph showed separation of conductors in the defibrillation lead from the main body of the lead.

An apparatus for the study of high temperature water radiolysis in a nuclear reactor: calibration of dose in a mixed neutron/gamma radiation field.

The cooling water of nuclear reactors undergoes radiolytic decomposition induced by gamma, fast electron, and neutron radiation in the core. To model the process, recombination reaction rates and radiolytic yields for the water radical fragments need to be measured at high temperature and pressure. Yields for the action of neutron radiation are particularly hard to determine independently because of the beta/gamma field also present in any reactor.
