Despite being targets of intervention practice and research for over 60 years, autistic people have been left out of the conversation. Until recently, nearly no research or implementation work has sought the input of autistic people in regard to the design of interventions and, more importantly, how the goals for such interventions are prioritized and determined. This reframe has profound implications for autism-focused interventions and research, most of which have aimed to reduce or eliminate autism symptoms, with variable empirical support (Bottema-Beutel, 2023).

Objectives: In the United States, autistic individuals experience disproportionate physical and mental health challenges relative to non-autistic individuals, including higher rates of co-occurring and chronic conditions and lower physical, social, and psychological health-related quality of life. The Autism Intervention Research Network on Physical Health (AIR-P) is an interdisciplinary, multicenter research network for scientific collaboration and infrastructure that aims to increase the life expectancy and quality of life for autistic individuals, with a focus on underserved or vulnerable populations. The current paper describes the development of the AIR-P Research Agenda.

Background: People with disabilities and chronic health conditions rely on a range of services and supports to complete daily tasks, maintain health, and participate in the community. Preliminary research suggests the COVID-19 pandemic greatly disrupted these services and this population may be particularly susceptible to unemployment.

Objective: Describe employment and service disruptions for individuals with disabilities and chronic health conditions during the onset of community-based spread of COVID-19 in the United States.

Autistic adults commonly experience mental health conditions. However, research rarely involves autistic adults in deciding priorities for research on mental healthcare approaches that might work for them. The purpose of this article is to describe a stakeholder-driven project that involved autistic adults in co-leading and designing research about priorities to address mental health needs.

Autistic adults have more health problems then their same-aged peers. Yet little research has been conducted that focuses on addressing these health problems. In order to guide future research, it is important to know what intervention studies have been done to improve health outcomes among autistic adults.

Cooling of beams of gold ions using electron bunches accelerated with radio-frequency systems was recently experimentally demonstrated in the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. Such an approach is new and opens the possibility of using this technique at higher energies than possible with electrostatic acceleration of electron beams. The challenges of this approach include generation of electron beams suitable for cooling, delivery of electron bunches of the required quality to the cooling sections without degradation of beam angular divergence and energy spread, achieving the required small angles between electron and ion trajectories in the cooling sections, precise velocity matching between the two beams, high-current operation of the electron accelerator, as well as several physics effects related to bunched-beam cooling.

A simple, analytically correct algorithm is developed for calculating "pencil" relativistic beam coordinates using the signals from an ideal cylindrical particle beam position monitor (BPM) with four pickup electrodes (PUEs) of infinitesimal widths. The algorithm is then applied to simulations of realistic BPMs with finite width PUEs. Surprisingly small deviations are found.

Background/aim: Besides late diagnosis, tumor metastasis and cancer relapse are the main reasons for the poor prognosis of patients with head and neck cancer. Several investigations have shown that tumor is of heterogeneous molecularity consisting of several subpopulations, with a broad range of biological behaviors. The ability and potential of tumor to infiltrate into vessels and into neighbouring organs, as well as the resistance to chemotherapeutical cancer therapy may be caused by cancer stem cells (CSCs).

Background: Hyperthyroidism in Graves' disease (GD) is often associated with the production of autoantibodies (TRAb) to the thyrotropin receptor (TSHR). Current manual second generation TRAb assays demonstrate high clinical sensitivity, but are labor-intensive and time consuming. Until recently, technical difficulties prevented the availability of an automatic TRAb assay.

A gas fluorescence beam profile monitor has been implemented at the relativistic heavy ion collider (RHIC) using the polarized atomic hydrogen gas jet, which is part of the polarized proton polarimeter. RHIC proton beam profiles in the vertical plane of the accelerator are obtained as well as measurements of the width of the gas jet in the beam direction. For gold ion beams, the fluorescence cross section is sufficiently large so that profiles can be obtained from the residual gas alone, albeit with long light integration times.

The determination of renal antigens in the urine with an immunoassay, based on monoclonal antibodies (moabs), is a noninvasive test system for the analysis and monitoring of renal injury. New moabs allowing an immunohistologic dissection of the human nephron were generated by a direct intrasplenic immunization of mice with pathologic urine samples. A sandwich enzyme immunoassay was developed to quantitate renal cell membrane antigens in the urine samples.
