title: The Identification and Magnitude Estimation of Occupational Stressors in the Industrial Hygiene Profession
Creators: name: Hinch, Judith
Publisher: name: Old Dominion University Libraries
Year: 1994

description: The industrial hygiene professional is responsible for the evaluation and control of hazards in the workplace. Job stress has been identified as a factor affecting the health, safety and productivity of workers and can be considered a workplace hazard.

This study involved the development of an instrument to identify and quantify sources of stress within a give profession. The industrial hygiene profession was chosen, though the method can be, and has been, used to evaluate stress in other groups of individuals. The method involved the identification of the most significant sources of stress by surveying a small number of the group. Then, the top 36 stressors were listed and one was selected to be a mid-point stressor. A questionnaire was developed in which subjects were asked to rate each stressor for intensity on a scale of zero to 1000 compared to the mid-point stressor. Also, the subjects were asked to give a rating for frequency: how often each item had been a source of stress to them in the last six months. In addition, the questionnaire contained demographic questions and selected items from the National Institute for Occupational Safety and Health (NIOSH) Generic Job Stress Questionnaire.

The instrument was mailed, with stamped, addressed return envelope to 500 randomly selected members of the American Industrial Hygiene Association (AIHA).

From the 212 respondents, the stressors were ranked according to their mean intensity and frequency ratings. Then, by combining intensity and frequency values, an estimation of relative importance that the most important sources industrial hygiene professional are was obtained, indicating of job stress to the 1) workload/not enough time, 2) paperwork, 3) lack of organizational communication, 4) administrative duties, 5) responsibility for legal compliance, 6) interruptions, and 7) making decisions involving human health. In addition, certain demographic variables were found to be significant for stress responses: a higher salary corresponded to higher stress. Generally, a lower age corresponded to lower stress. Stress peaked at age 50 to 55, however, and lower stress was noticed for those over age 55. Stress varied by type of employer and job description, also.

description:
Fluorophores containing donor, ? linker, and acceptor units are gaining importance in the field of organic chemistry, especially showing fluorescence at near-infrared region. Herein, we report the synthesis and optical properties of donor-?-acceptor fluorophores containing indole, benzo[e]indole, and benzothiazole as donor units. The cyanoacetic acid/ malononitrile were used as acceptor units. The Vilsmeier Haack linker substituted with different functional groups such as hydrogen, t-butyl and phenyl at the 4th position was the as ?-linker. The chlorine at meso-position was replaced with various nucleophiles such as piperidin-4-ylmethanol and pyridine-4-thiol. The fluorophores showed absorbance and emission maxima in NIR region (?abs =645 - 825 nm and ?em = 784 - 828 nm) with and high molar extinction coefficients and photothermal stability. The fluorophores had Stokes shift of 6  143 nm and quantum yield of 7 - 20%. The biodistribution of the synthesized fluorophores were studied in collaboration with Dr. Hak Soo Choi.

description: The Community of Practice (CoP) in Engineering and Social Justice seeks to expand the conversation about engineers’ professional and ethical responsibilities to include engineering as a sociotechnical field and considerations of social justice. Engineers typically receive training that enables them to recognize their professional and ethical responsibilities in broader environmental and societal contexts. However, both "professionalism" and "ethics" are often too narrowly construed to address considerations of social justice. This CoP aims to expand our thinking about engineering as a sociotechnical practice and ways that engineers can develop engineering solutions that respect society and all its members. This webinar discusses plans to achieve these aims. The webinar is a conversation between the OEC Fellows leading this CoP.

description: During the training of networks for distance metric learning, minimizers of the typical loss functions can be considered as "feasible points" satisfying a set of constraints imposed by the training data. To this end, we reformulate distance metric learning problem as finding a feasible point of a constraint set where the embedding vectors of the training data satisfy desired intra-class and inter-class proximity. The feasible set induced by the constraint set is expressed as the intersection of the relaxed feasible sets which enforce the proximity constraints only for particular samples (a sample from each class) of the training data. Then, the feasible point problem is to be approximately solved by performing alternating projections onto those feasible sets. Such an approach introduces a regularization term and results in minimizing a typical loss function with a systematic batch set construction where these batches are constrained to contain the same sample from each class for a certain number of iterations. Moreover, these particular samples can be considered as the class representatives, allowing efficient utilization of hard class mining during batch construction. The proposed technique is applied with the well-accepted losses and evaluated on Stanford Online Products, CAR196 and CUB200-2011 datasets for image retrieval and clustering. Outperforming state-of-the-art, the proposed approach consistently improves the performance of the integrated loss functions with no additional computational cost and boosts the performance further by hard negative class mining.

Publisher: name: Georgia State University
Year: 2022

description:
As a chronic disease, deaths caused by cancer are estimated to increase to 11.5 million by 2030. Patient response to treatment and chances of survival improves significantly when cancer is diagnosed at an early stage. MRI is a superior imaging modality but is limited due to the low relaxation rates of current contrast agent. Dr. Jenny Yangs lab engineered a protein-based MRI contrast agent with high relaxation rates. hProca32.collagen contains two cysteine residues and must be refolded to form intra-strand disulfide bonds, which is necessary for its activity. In this thesis, the purification and refolding of hProca32 were optimized to yield a pure protein that is approximately 80% monomer. Various formulation conditions are reported, which allow hProca32.collagen to have a good collagen-binding affinity (1.3 M). It exhibits good relaxivity values (30 and 42 mM-1s-1 for r1 and r2, respectively), which are 10-fold greater than clinically available contrast agents.

description: The bright soft X-ray transient Nova Muscae 1991 was intensively observed during its entire 8-month outburst using the Large Area Counter (LAC) onboard the Ginga satellite. Recently, we obtained accurate estimates of the mass of the black hole primary, the orbital inclination angle of the system, and the distance. Using these crucial input data and Ginga X-ray spectra, we have measured the spin of the black hole using the continuum-fitting method. For four X-ray spectra of extraordinary quality we have determined the dimensionless spin parameter of the black hole to be a/M = 0.63 (-0.19, +0.16) (1 sigma confidence level), a result that we confirm using eleven additional spectra of lower quality. Our spin estimate challenges two published results: It is somewhat higher than the value predicted by a proposed relationship between jet power and spin; and we find that the spin of the black hole is decidedly prograde, not retrograde as has been claimed.

description: Fetal neuroinflammation and prenatal stress (PS) may contribute to lifelong neurological disabilities. Astrocytes and microglia, among the brain's non-neuronal glia cell populations, play a pivotal role in neurodevelopment, predisposition to and initiation of disease throughout lifespan. One of the most common neurodevelopmental disorders manifesting between 1-4 years of age is autism spectrum disorder (ASD). A pathological glial-neuronal interplay is thought to increase the risk for clinical manifestation of ASD in at-risk children, but the mechanisms remain poorly understood and integrative, multi-scale models are needed. We propose a model that integrates the data across the scales of physiological organization, from genome to phenotype, and provides a foundation to explain the disparate findings on the genomic level. We hypothesize that via gene-environment interactions, fetal neuroinflammation and PS may reprogram glial immunometabolic phenotypes that impact neurodevelopment and neurobehavior. Drawing on genomic data from the recently published series of ovine and rodent glial transcriptome analyses with fetuses exposed to neuroinflammation or PS, we conduct an analysis on the Simons Foundation Autism Research Initiative (SFARI) Gene database. We confirm 21 gene hits. Using unsupervised statistical network analysis, we then identify six clusters of probable protein-protein interactions mapping onto the immunometabolic and stress response networks and epigenetic memory. These findings support our hypothesis. We discuss the implications for ASD etiology, early detection, and novel therapeutic approaches. We conclude with delineation of the next steps to verify our model on the individual gene level in an assumption-free manner.

description: We propose inducing Bose-Einstein condensation of magnons in a magnetic insulator by a heat flow oriented toward its boundary. At a critical heat flux, the oversaturated thermal gas of magnons accumulated at the boundary precipitates the condensate, which then grows gradually as the thermal bias is dialed up further. The thermal magnons thus pumped by the magnonic bulk (spin) Seebeck effect must generally overcome both the local Gilbert damping associated with the coherent magnetic dynamics as well as the radiative spin-wave losses toward the magnetic bulk, in order to achieve the threshold of condensation. We quantitatively estimate the requisite bias in the case of the ferrimagnetic yttrium iron garnet, discuss different physical regimes of condensation, and contrast it with the competing (so-called Doppler-shift) bulk instability.

description: "Gomus" is a Latin word translated as "earth", referring not to the planet itself, but to its upper, fertile layer. It becomes fertile due to the decomposition of organic matter - leaves, grass, animal remains and their metabolic products. Only 5% of the total mass of biohumus is enough for soil fertility. Forming these percentages is not easy. It takes 100 years to create a 10 cm layer. Man-made pollution, unintended use of land slows down the process even more, makes the soil dead.

description: The region of Southern Louisiana stretching from Baton Rouge to New Orleans, along the Mississippi River, is nicknamed Cancer Alley, due to the disproportionately high cancer rates observed within the region. This thesis is a narrative literature review that analyzes the scientific literature and the raw data that have been published regarding some of the major causes of this pathology, as well as the link between said causes and the existence of Cancer Alley. Specifically, this analysis finds that the large presence of the petrochemical industry within this region, and the consequent sustained environmental pollution on part of petrochemical plants, contributes to the disparate outcomes in cancer incidence that are observed within Cancer Alley. Moreover, the analysis finds that these disparities occur quite heavily along racial and socioeconomic lines, with the brunt of the burden being borne by predominantly low-income and predominantly-Black neighborhoods, where air toxins such as benzene and formaldehyde have a higher presence. The analysis also finds that the petrochemical industry partakes in said environmental pollution with relative impunity, due to the industry’s size and political power, which renders residents powerless against the industry’s lobby. The findings of this analysis could prove significant in that they may spark some level of discussion that will not only politically empower marginalized communities that are victimized by environmental injustice, but may also lead to safety and environmental regulations on the petrochemical industry within the region.

description: We present MDP Playground, a testbed for Reinforcement Learning (RL) agents with dimensions of hardness that can be controlled independently to challenge agents in different ways and obtain varying degrees of hardness in toy and complex RL environments. We consider and allow control over a wide variety of dimensions, including delayed rewards, sequence lengths, reward density, stochasticity, image representations, irrelevant features, time unit, action range and more. We define a parameterised collection of fast-to-run toy environments in OpenAI Gym by varying these dimensions and propose to use these to understand agents better. We then show how to design experiments using MDP Playground to gain insights on the toy environments. We also provide wrappers that can inject many of these dimensions into any Gym environment. We experiment with these wrappers on Atari and Mujoco to allow for understanding the effects of these dimensions on environments that are more complex than the toy environments. We also compare the effect of the dimensions on the toy and complex environments. Finally, we show how to use MDP Playground to debug agents, to study the interaction of multiple dimensions and describe further use-cases.

title: Human Immunodeficiency Virus (HIV)/Hepatitis B Virus (HBV) Risk Perception Related to Needlestick Injuries at a Medical School in Norfolk, Virginia
Creators: name: Hartman, Ronald B.
Publisher: name: Old Dominion University Libraries
Year: 1996

description: A limited number of studies have been conducted to assess the perceptions of risk of medical students and residents for acquiring Human Immunodeficiency Virus (HIV) or Hepatitis B Virus (HBV) via percutaneous (needlestick) injuries while performing clinical training. The purpose of this study is to investigate these perceptions of risk, and to determine whether there is an association between a high perception of risk and a low incidence of needlestick injury. The method of investigation was a four-page survey questionnaire. The instrument was investigated for reliability by use of a pilot study with a small group of medical students and residents at a medical school in Norfolk, Virginia. The survey instrument was then redesigned accordingly, and administered by anonymous mailings to 351 medical students in their third and fourth year of study, and all residents in their first and second year of residency. Questions asked included demographics, level of training, and number of needlestick (hollow-needle) injuries or other sharps injuries (e.g., suture needles and suture blades). The majority of questions asked each individual to rate their degree of concern or their personal perception of risk of acquiring HIV /HBV from needlestick or other "sharps" injuries received during clinical phases of their training. Questions also addressed their personal beliefs about occupational transmission of these bloodborne pathogens, and use of protective barriers. All were measured on a Likert scale where the student was asked to indicate his/her agreement or disagreement with each statement, where 1 = "strongly disagree" to 4 = "strongly agree." Questionnaires were returned anonymously by the students via self-addressed stamped envelopes to the investigator. The response rate was 37%. All data was collected, stored, and analyzed using the Statistical Package for the Social Sciences (SPSSx).

It was found that the independent variable of risk perception scores was not associated with the number of needlestick injuries, the dependent variable, and that by itself, only the independent variable of study year was significantly associated with the number of needlestick injuries. Additionally, a statistically significant difference was found between the non-reporting and reporting behaviors of the study population. Rates of nonreporting ranged 44 - 75% for needlestick injuries. Because the non-reporting rates of the medical students and residents under study were significantly high, it is recommended that additional education programs be established, and measures taken which will reduce or change the perception that a needlestick injury or body fluid splash is of little consequence.

description: The optical counterpart of the black-hole soft X-ray transient Nova Muscae 1991 has brightened by $Δ{V}\approx0.8$ mag since its return to quiescence 23 years ago. We present the first clear evidence that the brightening of soft X-ray transients in quiescence occurs at a nearly linear rate. This discovery, and our precise determination of the disk component of emission obtained using our $simultaneous$ photometric and spectroscopic data, have allowed us to identify and accurately model archival ellipsoidal light curves of the highest quality. The simultaneity, and the strong constraint it provides on the component of disk emission, is a key element of our work. Based on our analysis of the light curves, and our earlier measurements of the mass function and mass ratio, we have obtained for Nova Muscae 1991 the first accurate estimates of its systemic inclination $i=43.2^{+2.1}_{-2.7}$ deg, and black hole mass $M=11.0^{+2.1}_{-1.4}\ M_\odot$. Based on our determination of the radius of the secondary, we estimate the distance to be $D=4.95^{+0.69}_{-0.65}$ kpc. We discuss the implications of our work for future dynamical studies of black-hole soft X-ray transients.

description: We investigated the dynamical behaviors of bimodular continuous attractor neural networks, each processing a modality of sensory input and interacting with each other. We found that when bumps coexist in both modules, the position of each bump is shifted towards the other input when the intermodular couplings are excitatory and is shifted away when inhibitory. When one intermodular coupling is excitatory while another is moderately inhibitory, temporally modulated population spikes can be generated. On further increase of the inhibitory coupling, momentary spikes will emerge. In the regime of bump coexistence, bump heights are primarily strengthened by excitatory intermodular couplings, but there is a lesser weakening effect due to a bump being displaced from the direct input. When bimodular networks serve as decoders of multisensory integration, we extend the Bayesian framework to show that excitatory and inhibitory couplings encode attractive and repulsive priors, respectively. At low disparity, the bump positions decode the posterior means in the Bayesian framework, whereas at high disparity, multiple steady states exist. In the regime of multiple steady states, the less stable state can be accessed if the input causing the more stable state arrives after a sufficiently long delay. When one input is moving, the bump in the corresponding module is pinned when the moving stimulus is weak, unpinned at intermediate stimulus strength, and tracks the input at strong stimulus strength, and the stimulus strengths for these transitions increase with the velocity of the moving stimulus. These results are important to understanding multisensory integration of static and dynamic stimuli.

description: First-principles calculations are made for the primary pyroelectric coefficients of wurtzite GaN and ZnO. The pyroelectricity is attributed to the quasiharmonic thermal shifts of internal strains (internal displacements of cations and anions carrying their Born effective charges). The primary (zero-external-strain) pyroelectricity dominates at low temperatures, while the secondary pyroelectricity (the correction from external thermal strains) becomes comparable with the primary pyroelectricity at high temperatures. Contributions from the acoustic and the optical phonon modes to the primary pyroelectric coefficient are only moderately well described by the corresponding Debye function and Einstein function respectively.

Body length 2.4–4.0 mm; epicuticle with microdenticles; middle-sized, smooth clothing setae; antennae with 20–23 antennomeres; sensillum of third antennomere in dorsal position; short (ma, la) and long (lp), poorly barbed notal macrosetae; marginal setae short and smooth or with a few apical barbs; 1+1 short ma macrosetae on I–VII urotergites, 1+1 la, 1+1 lp on V–VII urotergites, 1+1 mp, 3+3 lp on VIII urotergite and 1+1 mp, 5+5 lp on IX abdominal segment; male with two separated areas of glandular g 1 -setae; cerci covered in long macrosetae with distal barbs and a few clothing setae but with swollen latero-interior macrosetae on proximal articles.
Habitat and distribution
Soil-dwelling species with a preference for the upper layers of the soil (O and A horizons). It extends from the centre and west of the Pyrenees towards the Basque and the Cantabrian Mountains (Denis 1932b; Condé & Mathieu 1957; Sendra & Jiménez 1983). The presence of this species outside those regions should be further revised with new material (Blesić 1984, 1987, 1988, 1992, 1997 b, 1998a, 1998 b, 2000b; Ionescu 1955; Christian 2003).

description: Image processing concepts can visualize the different anatomy structure of the human body. Recent advancements in the field of deep learning have made it possible to detect the growth of cancerous tissue just by a patient's brain Magnetic Resonance Imaging (MRI) scans. These methods require very high accuracy and meager false negative rates to be of any practical use. This paper presents a Convolutional Neural Network (CNN) based transfer learning approach to classify the brain MRI scans into two classes using three pre-trained models. The performances of these models are compared with each other. Experimental results show that the Resnet-50 model achieves the highest accuracy and least false negative rates as 95% and zero respectively. It is followed by VGG-16 and Inception-V3 model with an accuracy of 90% and 55% respectively.

description: With the domination of music broadcasting through the internet, detecting audio problems on sound files became more important. Essentia and other similar sound libraries enabled to detect audio problems automatically, which made the detection process faster, cheaper, and more accurate. These algorithms were mostly applied on music files which are usually recorded with adequate equipment in studio environment, and afterwards that are mixed and mastered. But there are many types of sounds other than music that can be recorded and uploaded to web. Freesound is a web platform that has currently the largest collection of sounds that are recorded in different environments, using different equipment, and tagged with suitable keywords. FSD50K is the dataset that includes 51,197 carefully annotated sounds gathered from Freesound Platform.
 In this study, five of the mostly used automatic audio problem detection algorithms were selected. These are discontinuity, gap, click, hum, and clipping problems. Using Essentia, these algorithms were applied on FSD50K. Some bugs in the algorithms were detected and fixed, or some limitations were identified in their usage. For each audio problem, the sound classes that have the most problematic audio file percentages were detected.
 Besides these already implemented algorithms, a detection algorithm for asymmetry, that is another property of sound, and which does not always have to be a problem, was implemented and results were analyzed.
 An audio analyzer was implemented and added to Freesound Platform that allows users to filter the sound they are looking for based on whether the sound is problematic or not, according to the audio problem detection algorithms tested in the study.

Non-Reciprocal Wave Propagation in Spatiotemporal Periodic Structures
Creators: name: Trainiti, Giuseppe

Publisher: name: arXiv
Year: 2016
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We study longitudinal and transverse wave propagation in beams with elastic properties that are periodically varying in space and time. Spatiotemporal modulation of the elastic properties breaks mechanical reciprocity and induces one-way propagation. We follow an analytic approach to characterize the non-reciprocal behavior of the structures by analyzing the symmetry breaking of the dispersion spectrum, which results in the formation of directional band gaps and produces shifts of the First Brilloin Zone limits. This approach allows us to relate position and width of the directional band gaps to the modulation parameters. Moreover, we identify the critical values of the modulation speed to maximize the non-reciprocal effect. We numerically verify the theoretical predictions by using a finite element model of the modulated beams to compute the transient response of the structure. We compute the two-dimensional Fourier transform of the collected displacement fields to calculate numerical band diagrams, showing excellent agreement between theoretical and numerical dispersion diagrams.

description: We use high resolution N-Body simulations to study the concentration and spin parameters of dark matter haloes in the mass range $10^8\, {\rm M}_{\odot}\, h^{-1} < {\rm M} < 10^{11}\, {\rm M}_{\odot}\, h^{-1}$ and redshifts $5{}5$ concentration$-$mass ($c(M)$) relation that is almost flat and well described by a simple power-law for both NFW and Einasto fits. The intrinsic scatter around the mean relation is $Δc_{\rm{vir}}{\sim1}$ (or 20 per cent) at $z=5$. We also find that the analytic model proposed by Ludlow et al. reproduces the mass and redshift-dependence of halo concentrations. Our best-fit Einasto shape parameter, $α$, depends on peak height, $ν$, in a manner that is accurately described by $α{=}0.0070ν^2{+}0.1839$. The distribution of the spin parameter, $λ$, has a weak dependence on equilibrium state; $λ$ peaks at roughly ${\sim}0.033$ for our relaxed sample, and at ${\sim}0.04$ for the full population. The spin--virial mass relation has a mild negative correlation at high redshift.

description: We study, by means of a Monte Carlo simulator, the hot phonon effect on the relaxation dynamics in photoexcited graphene and its quantitative impact as compared to considering an equilibrium phonon distribution. Our multi-particle approach indicates that neglecting the hot phonon effect significantly underestimates the relaxation times in photoexcited graphene. The hot phonon effect is more important for a higher energy of the excitation pulse and photocarrier densities between $1$ and $3\times 10^{12} \mathrm{~cm}^{-2}$. Acoustic intervalley phonons play a non-negligible role, and emitted phonons with wavelengths limited up by a maximum (determined by the carrier concentration) induce a slower carrier cooling rate. Intrinsic phonon heating is damped in graphene on a substrate due to additional cooling pathways, with the hot phonon effect showing a strong inverse dependence with the carrier density.
