Security Of Mobile Radiological Sources: Overview Of Industry Applied Technologies, Ann M. Archer, Ashleigh Wickham

International Journal of Nuclear Security

Small radiological sources used in industrial settings recurrently require transit between job sites. Securing these sources, while stationary, can be addressed with standard security approaches and equipment. Transport of these sources increases the risk and complexity of managing and maintaining control of these sources. Implementing methodologies to securely monitor and locate sources improves response and resolution of anomalous events during transit. The Mobile Source Transit Security (MSTS) system was developed to improve security and provide situational awareness of these mobile sources throughout their job cycle. The MSTS development effort focused on creating a set of systems that could be successfully …

Alzheimer's disease (AD) is a neurodegenerative disease that commonly causes dementia. Identifying biomarkers for the early detection of AD is an emerging need, as brain dysfunction begins two decades before the onset of clinical symptoms. To this end, we reanalyzed untargeted metabolomic mass spectrometry data from 905 patients enrolled in the AD Neuroimaging Initiative (ADNI) cohort using MS-DIAL, with 1,304,633 spectra of 39,108 unique biomolecules. Metabolic profiles of 93 hydrophilic metabolites were determined. Additionally, we integrated targeted lipidomic data (4873 samples from 1524 patients) to explore candidate biomarkers for predicting progressive mild cognitive impairment (pMCI) in patients diagnosed with AD …


Phytoplankton Responses To Changing Irradiance And Carbon Fertilization, Alison Siersma Dec 2024

Phytoplankton Responses To Changing Irradiance And Carbon Fertilization, Alison Siersma

Graduate Theses and Dissertations (2019 - present)

Phytoplankton play a crucial role in marine ecosystems due to their innate ability to fix carbon. As atmospheric CO2 levels continue to rise from fossil fuel combustion, the resulting increase in dissolved CO2 and the concurrent decrease in ocean pH are likely to impact the phytoplankton community. The response of phytoplankton to elevated CO2 can vary significantly among species and environmental conditions (e.g. light, temperature, nutrient availability). To address these variations, an experiment was conducted using a controlled photobioreactor system, maintaining high and low light, constant temperature, nutrient levels, and two pCO2 concentrations. This study focused on two regionally relevant …

Zero-G Exercise Equipment, Charisse Biglete, Jake Brajevich, James Monroe, Ethan Siahpush

Mechanical Engineering

In a micro-gravitational environment, the body undergoes less loading than that found on Earth. This leads to muscular atrophy, Osteoporosis, decreases in protein synthesis, and various other undesirable outcomes. To prevent this, astronauts undergo a strict exercise regime to maintain their health. The current exercise equipment available for spacecraft is large, heavy, complicated to use, costly, and unsafe. There is a definite need for the re-engineering of the exercise equipment to be used by astronauts while in microgravity environments to rectify these issues.

Examining The Relationship Between Internalizing, Externalizing, And Psychotic Psychopathology At Five Levels Of Criminal Risk, Cooper Mitchell Sparks Dec 2024

Examining The Relationship Between Internalizing, Externalizing, And Psychotic Psychopathology At Five Levels Of Criminal Risk, Cooper Mitchell Sparks

Theses

Though it is well established that mental illness is not a primary risk factor for criminal justice involvement, the relationship between mental illness and criminal risk with justice-involved persons with mental illness is not well understood (Bonta, et al., 1998; Morgan, et al., 2010; Skeem, et al., 2014). Specifically, psychopathology has not been understood at different levels of criminal risk. Using the Five-Level Risk and Needs System for criminal risk (Hanson, et al., 2017), the current study aimed to identify mean differences between different domains of psychopathology (i.e., internalizing, externalizing, and psychotic psychopathology) across five levels of criminal risk.

A Focus On The Social Validity Of Treating Stereotypy Using Response Interruption And Redirection, Maggie Grace Ratcliff Dec 2024

A Focus On The Social Validity Of Treating Stereotypy Using Response Interruption And Redirection, Maggie Grace Ratcliff

Theses

Stereotypy refers to a class of operant repetitive motor and vocal responses with no readily apparent goal or purpose (Rapp & Vollmer, 2005; Singer, 2009; Wunderlich et al., 2023). Although most stereotypy is clinically insignificant and does not warrant treatment (i.e., nail biting, hair twirling), some stereotypy persists at a frequency or severity which interferes with skill acquisition, social interactions, and daily living skills. Stereotypy which persists at this level is considered clinically significant and is often the target of treatment (Wunderlich et al., 2023). A variety of evidence-based treatments for the reduction of stereotypy exist, though some neurodiversity advocates …

文德 : 中國文論尚德精神的理論基石, Xinglu Zhou Dec 2024

文德 : 中國文論尚德精神的理論基石, Xinglu Zhou

嶺南學報 Lingnan Journal of Chinese Studies

“文德”是中國文論之作家論的基點,貫穿數千年中國文論史,形成了尚德的中國文學傳统。“文人”在社會治理與文明傳承中擔任著重要的任務,因此對“文人”的道德品質有嚴格的要求,而文藝創作天然地崇尚超越規矩、擺脱束縛的精神自由,二者之間構成内在的衛突,於是衍生出“文人無行”的命題。傳统文學批評從正面强調“文德”,德爲主,文爲輔,主次鮮明。面對不同的社會文化現狀,基於不同的思想立場,對“文德”的理解不盡相同。或提倡士先器識而後文藝,或强調士人“不俗”的品格,或主張“性情之正”,以理正情,對情感的抒泄加以疏導和匡正。至明清時期標尚“志士”之詩文,心憂天下,關懷民瘼,個人情懷緊緊聯繫著社會苦難和時代劇變,傳统的“文德”論的内涵因時因地而發展變化,當前中國文論應該有新時代的“文德”論。

Literary Virtue is the basic point of the writer’s theory in Chinese literary theory. It runs through the history of Chinese literary theory for thousands of years and forms a Chinese literary tradition that advocates virtue. Literati played an important role in social governance and civilization inheritance. Therefore, there are particularly strict requirements for the moral quality of literati. Literary and artistic creation naturally advocates spiritual freedom that transcends rules and gets rid of constraints. The two constitute an inner conflict gave rise to the proposition that “literati lack morals”. Traditional literary criticism emphasizes Literary Virtue from the front, …

Estrogens promote binge alcohol drinking and contribute to sex differences in alcohol use disorder. However, the mechanisms are largely unknown. This study aims to test if estrogens act on 5-hydroxytryptamine neurons in the dorsal raphe nucleus (5-HTDRN) to promote binge drinking. We found that female mice drank more alcohol than male mice in chronic drinking in the dark (DID) tests. This sex difference was associated with distinct alterations in mRNA expression of estrogen receptor α (ERα) and 5-HT-related genes in the DRN, suggesting a potential role of estrogen/ERs/5-HT signaling. In supporting this view, 5-HTDRN neurons from naïve male mice had …

Exercise intolerance, a hallmark of heart failure with preserved ejection fraction (HFpEF) exacerbated by obesity, involves unclear mechanisms related to skeletal muscle metabolism. In a “2-hit” model of HFpEF, we investigated the ability of exercise therapy (voluntary wheel running) to reverse skeletal muscle dysfunction and exercise intolerance. Using state-of-the-art metabolic cages and a multiomic approach, we demonstrate exercise can rescue dysfunctional skeletal muscle lipid and branched-chain amino acid oxidation and restore exercise capacity in mice with cardiometabolic HFpEF. These results underscore the importance of skeletal muscle metabolism to improve exercise intolerance in HFpEF.

Endurance exercise training is known to reduce risk for a range of complex diseases. However, the molecular basis of this effect has been challenging to study and largely restricted to analyses of either few or easily biopsied tissues. Extensive transcriptome data collected across 15 tissues during exercise training in rats as part of the Molecular Transducers of Physical Activity Consortium has provided a unique opportunity to clarify how exercise can affect tissue-specific gene expression and further suggest how exercise adaptation may impact complex disease-associated genes. To build this map, we integrate this multi-tissue atlas of gene expression changes with gene-disease …

As of 2023, it is estimated that 6.7 million individuals in the United States live with Alzheimer’s disease (AD). Prior research indicates that AD disproportionality affects females; females have a greater incidence rate, perform worse on a variety of neuropsychological tasks, and have greater total brain atrophy. Recent research shows that hippocampal functional connectivity differs by sex and may be related to the observed sex differences in AD, and apolipoprotein E (ApoE) ε4 carriers have reduced hippocampal functional connectivity. The purpose of this study was to determine if the ApoE genotype plays a role in the observed sex differences in …

White matter hyperintensities (WMH) and infarcts found on magnetic resonance imaging (MR infarcts) are common biomarkers of cerebrovascular disease. In this review, we summarize the methods, publications, and conclusions stemming from the Alzheimer's Disease Neuroimaging Initiative (ADNI) related to these measures. We combine analysis of WMH and MR infarct data from across the three main ADNI cohorts with a review of existing literature discussing new methodologies and scientific findings derived from these data. Although ADNI inclusion criteria were designed to minimize vascular risk factors and disease, data across all the ADNI cohorts found consistent trends of increasing WMH volumes associated …
