description: Chronic stress in early childhood can have negative implications for future life outcomes. This thesis analyzes the relationships between chronic loneliness, perceptions of crime, childhood instability, and classroom behaviors in children. To answer this research question, web scraping was used on Twitter to collect tweets related to the perception of crime in Elkhart, Indiana between June 2016 and May 2019. Topic modeling was conducted on the Twitter data to explore the evolution of topics over time. Crime offense data was collected from an FBI database to analyze actual crime rates in 2016 and 2018. A dataset from the CAPS educational program in Elkhart, Indiana was used to analyze relationships between chronic loneliness, delay of gratification, childhood instability, and other early childhood factors. Logistic and linear regression was conducted on the CAPS data to analyze relationships between the variables. The results indicate that: (i) the perception of crime in the community does not align with actual crime rates, and (ii) no significant relationship exists between childhood instability factors and self-regulation skills in children within the study. This thesis emphasizes the need for policy interventions in early childhood to alleviate chronic stressors that arise from internal and external instability factors in a child’s life. In turn, these interventions will allow for the improvement of future life outcomes in children with social instability.

description: To describe a series of eight adult patients with primary orbital sarcoma and to review the existing literature on orbital sarcoma and post-irradiation sarcoma. Report of eight cases and literature review. We report eight cases of primary orbital sarcoma, three of which were radiation-induced. Only one patient had a history of retinoblastoma. The most common presentations were painful proptosis and reduced vision. Most tumours arose in the extraconal compartment. The overall median age at diagnosis was 50 years. The pathology comprised a diverse group of tumours. Treatment and outcome varied between patients and their clinical circumstances. Adult primary orbital sarcomas are rare. They can comprise a variety of tumour types and are difficult to treat. Irradiation is a significant risk factor, and the incidence of post-irradiation sarcoma of the orbit may be increasing due to the widespread use of radiotherapy and improved survival of patients with cancer. Post-irradiation sarcoma should be considered in the differential diagnosis of an orbital space-occupying lesion in a patient with a history of radiotherapy.

description: We are interested in the distribution of Wishart samples after forgetting their scaling factors. We call such a distribution a projective Wishart distribution. We show that projective Wishart distributions have strong links with the affine-invariant geometry of symmetric positive definite matrices in the real case or Hermitian positive definite matrices in the complex case. First, the Fr{é}chet mean of a projective Wishart distribution is the covariance parameter, up to a scaling factor, of the corresponding Wishart distribution. Second, in the case of 2 by 2 matrices, the densities have simple expressions in term of the affine-invariant distance.

description: Merkel cell carcinoma of the eyelid (MCCE) is a rare yet aggressive neuroendocrine tumour associated with significant morbidity and mortality. This study aimed to investigate survival trends and demographic factors related to MCCE, 2000–2019, using the Surveillance, Epidemiology, and End Results (SEER) Program. Cases were analysed by demographic parameters, disease properties, and survival. Statistical analyses were performed via a dedicated computerized software package. A total 349 cases of MCCE were identified, accounting for 2% of all MCC cases in the United States during that time. Of note, the incidence of MCCE remained stable over the study period (p = .35). Female patients accounted for 56% of the cases, and males for 44%. White patients accounted for 90.8% of the the cases, and Black patients for 2.9%. MCCE incidence increased with age, with the majority of patients age 85+ (p < .05). Incidence was greatest in metropolitan areas and among those with median incomes >$75,000/year. Income correlated with likelihood of MCCE diagnosis (p < .05). Analysis of 5-year survival data showed 20% of the patients died due to MCCE within 5 years of diagnosis. Of these, the majority died within one year of diagnosis. Consistent with previous reports, most patients were white, female, and age 85+.Incidence correlated with metropolitan environments and median income. While most patients did not die from MCCE, majority of recorded deaths occurred within one year of diagnosis.

subject: Rhesus Macaque

description: In zoos, recommendations for transferring animals between institutions are made based on the capacity of individual institutions, the current genetic distribution of the ex situ population of the species, and the long-term sustainability of the population. These types of human-induced dispersal have the potential to destabilize not only the social group receiving a novel individual, but the social group from which the transferred individual was removed and are often, therefore, contrary to the conservation aims of population management in zoos. Removal of individuals that manage group conflict has been shown to be deleterious to group stability and cohesion; however, identifying such individuals has been difficult. Third-party intervention has been described as an important mechanism for maintaining group stability in group living primates. An individual’s personality, rank, and power style have been shown to be predictors of successful intervention. This assessment provides analytical results for the distribution and importance of individual roles, particularly dissipaters of social conflict, within rhesus macaque social networks. In this assessment, 36 individuals from 6 different half-acre field cages were identified from a social network dataset based on the count of third-part interventions in non-kin conflicts. For each cage, the top three dissipaters and top three individuals with no dissipation were selected for biobehavioral assessment. The BioBehavioral Assessment program is designed to characterize temperament, emotionality, and behavioral and physiological responsiveness to novel environments and data have been used in multiple studies to understand the causes and consequences of variation in individual temperament and behavioral responsiveness. This assessment identifies individual factors leading to conflict dissipation: temperament determined within-troop and in a novel environment, behavioral and physiological responses to stress, and individual and group-level network measures. This study also demonstrated that conflict dissipaters differed from other interveners because they were posed to behaviorally and physiologically cope better with the stress of unpredictability; that specific social roles were based on individual attributes which influence how the troop agreed on the dominance status of that individual, which also contributed to a successful intervention; and suggested that males engaging in conflict appeared to play a role in dissipation, whereas female engagement in non-kin conflict was seemingly more complex and requires continued investigation

description: The multitude of flowers frames used in American mourning culture of the nineteenth century up to World War I have left behind a vivid, visual history of the changing perceptions about death. This thesis will explore how funeral flower frames reveal an emotional and cultural shift from fears of hellfire and damnation, to a concept of restful sleep for the redeemed soul and hope of being reunited in a better place. The use of flowers at funerals evolved from a way to mask the physical and sensory ugliness of death to messages of religious and sentimental beauty, to individualized and symbolic representations of the deceased, and finally to conventional tokens for the funeral director to use decoratively. This thesis will explore the relationship between the presence of wire flower frames at funerals and the changing perceptions of death throughout the nineteenth century and up to World War I.

description: In view of the emerging technologies in the virtual reality industry, VR provides a practical platform to train people in a safe and time-saving manner through serious virtual training tasks. Recent researches validate the effectiveness of virtual training, especially, it has been proved that personalized training in virtual reality is efficient enough to emphasize users' specific skills. Inspired by the recent works that automatically synthesize different training scenarios to achieve different personalized training targets through optimization techniques that can be applied to substitute manual configuration. My dissertation focuses on three interdisciplinary areas including personalized wheelchair training, exertion-aware path generation, and construction safety training. We first introduce an optimization-based approach for automatically generating virtual scenarios for wheelchair training in virtual reality. We then illustrate a novel approach for generating paths with desired exertion properties. After this, we will present a novel approach to synthesize construction safety training scenarios to train the users on how toproficiently inspect the potential hazards within the construction sites in virtual reality. In the end, we will draw a conclusion on existing research results and prospect the future trend of synthesizing personalized training scenarios in virtual reality.
Role Of Gas In Supporting Global Spiral Structure In Galaxies

Subjects: Discs in galaxies

description: It is well-known that the two-armed spiral density wave in a galactic disk would be destroyed by group transport within about a billion years, as shown in a classic paper by Toomre. We include the low-velocity dispersion component, namely gas, along with stars in the formulation of the density wave theory, and obtain the dispersion relation for this coupled system. We show that the inclusion of gas makes the group transport slower, thus allowing the pattern to persist longer – for several billion years. Though still less than the Hubble time, this allows the spiral structure to be more long-lived. Further, we study NGC 6946, NGC 2997, and M 51, and show that the inclusion of gas is essential to get a stable density wave for the observed values of pattern speeds for these galaxies. Thus, the inclusion of even a small amount of gas (~ 15820 % by mass) has a significant dynamical effect on the value of pattern speed allowed, and hence on the secular evolution of a galactic disc.
First records of Phylloscopus collybita brevirostris (Strickland, 1837) and Ph. c. caucasicus (Loskot, 1991) in north-western Europe
Creators: name: de Knijff, Peter
Publisher: name: Zenodo

description: Six subspecies of the Common Chiffchaff Phylloscopus collybita are usually recognised, of which three are known to occur in North-western Europe: collybita, abietinus, and tristis. Based on DNA sequences, the taxa brevirostris and caucasicus are recorded from North-western Europe for the first time. Both taxa occur at the south-eastern edges of the species’ breeding range, in the Middle East and the Caucasus, respectively. Movements outside the breeding season of these two taxa have been largely undescribed. A single brevirostris in Germany concerned a spring record, whereas five caucasicus in the Netherlands and Germany were recorded during late autumn.  Based on published information, neither the genetic variation in the mitochondrial (mtDNA) ND2 gene (Raković et al. 2019), nor in the mtDNA CYTB gene (Helbig et al. 1996, Marova et al. 2021) enabled a reliable differentiation of brevirostris from caucasicus. Here we describe in some detail how the additional mtDNA-fragments do facilitate the identification of brevirostris and caucasicus unequivocally.

description: This is a legal study of the arrangements made in eight European countries to secure the enforcement of social rights. It is a study carried out as a response to the overall bEUcitizen research interest in potential barriers to a EU-citizenship. The aim of the study is to investigate the possibilities and impediments for EU-citizens in Denmark, Estonia, Germany, Poland, the Netherlands, Spain, Sweden and the United Kingdom to enforce their (moral and/or legal) social rights in the fields of education, health care, housing and social assistance. Our focus is on redress mechanisms. It is a study that is comparative in several dimensions (between rights, between citizens, between countries and potentially also between different legal levels). Results indicate that if rights are provided and ifredress is offered, we have in the countries studied found no formal hindrances that discriminate against mobile EU-citizens. This said, we also learn that extra-procedural hindrances are a reality and that they create barriers especially problematic to mobile EU-citizens but also to EU-citizens living in their native countries. We conclude that the EU-citizenship project would gain from an exploration of new and innovative means of creating systems and institutions for the provision of basic, fundamental, social protection to secure life, dignity and means of social inclusion to all its citizens, no matter where in Europe they live or work. Europe is a region of welfare states and it is a barrier to the fulfilment of a well-functioning EU-citizenship not to fully recognise this fact.
title: Rapid and Precise Tumor Classification: A Neural Network Approach for Malignant and Benign Tumor Distinction
Creators: name: Peng, Kenneth
Publisher: name: George Mason University
Year: 2023

description: The early and accurate diagnosis of cancer significantly impacts the effectiveness of treatment strategies. Traditional diagnostic methods, while effective, are often time-consuming and may not always reach optimal accuracy. We aim to demonstrate the application of a neural network model, developed using TensorFlow that is able to distinguish between malignant (cancerous) and benign (non-cancerous) tumors, addressing the critical need for rapid and precise diagnosis in oncological care. Utilizing a large dataset containing categories consisting of the mean, standard error (SE), and worst (or largest) measurements of each major tumor characteristic, we preprocessed the data to separate features from labels and split it into training and testing sets. We developed the model on Google Colab, then tested and trained through thousands of epochs before finalizing on a model that is monitored through metrics including loss (binary cross entropy) and accuracy. The final neural network accurately predicted tumor diagnosis (whether it is malignant or benign) with an accuracy rate of 99.12%, and only having a loss (the measure of error in prediction) of 0.0468, showcasing both high reliability and precision in its predictions.

description: As an embodied and spatial medium, virtual reality is proving an attractive proposition for robot teleoperation in hazardous environments. This paper examines a nuclear decommissioning scenario in which a simulated team of semi-autonomous robots are used to characterise a chamber within a virtual nuclear facility. This study examines the potential utility and impact of sonification as a means of communicating salient operator data in such an environment. However, the question of what sound should be used and how it can be applied in different applications is far from resolved. This paper explores and compares two sonification design approaches. The first is inspired by the theory of cognitive metaphor to create sonifications that align with socially acquired contextual and ecological understanding of the application domain. The second adopts a computationalist approach using auditory mappings that are commonplace in the literature. The results suggest that the computationalist approach outperforms the cognitive metaphor approach in terms of predictability and mental workload. However, qualitative data analysis demonstrates that the cognitive metaphor approach resulted in sounds that were more intuitive, and were better implemented for spatialisation of data sources and data legibility when there was more than one sound source.

I2R Glove Bag for the preparation of an in-situ lithium battery cell

Publisher: name: Zenodo
Year: 2005

description: Lithium ion batteries are assembled in an inert atmosphere to prevent 1) metallic lithium from reacting with oxygen, nitrogen, and humidity in air and 2) LiPF6, the electrolyte, reacting with humidity in air. Battery laboratories are equipped with stationary glove boxes and allow for an easy and safe assembly of such batteries.  A new situation arises when battery researchers have to assemble batteries at locations where no suitable glove box is available. The batteries had to be assembled and tested at a synchrotron. The only way to perform this task without corruption of the batteries or its parts was using an I2R Glove Bag. The glove bag was connected to an argon bottle. Cell assembly took only few minutes and occurred in walking distance from the beamline at the synchrotron where measurements took place. When the cell was opened after characterization at the synchrotron, the lithium metal showed no apparent traces of corrosion, proof that the glove bag provided safe (dry, no oxygen, no nitrogen) environment for the sensitive lithium metal and LiPF6.

description: The  HALOGAS  (Hydrogen  Accretion  in  LOcal  GAlaxieS)  survey  with the Westerbork  Synthesis  Radio  Telescope  is  the  most  sensitive  systematic survey of the diffuse neutral hydrogen component in nearby spiral galaxies so far.  The  5-sigma  column  density  sensitivity  reached for the sample of 22 galaxies is ~10^19 atoms cm^-2 over the typical line width of the neutral gas in our target galaxies. The 3D observations are sensitive enough to perform detailed  kinematical  and  dynamical  analyses  of  the  extended  (vertical)  disk structure of our targets. Additionally, we are able to provide a census of the complete  cold  neutral  cloud  population  above  the  mass  detection  limit  for individual objects of 10^5 solar masses on average. Our results are relevant in the context of theories describing star formation feedback on the gaseous interface of the galaxy disks with their surroundings, as well as gas accretion from  the  intergalactic  medium.  Most  notably,  we  find  that  the  presence  of anomalous,  slowly  rotating  extraplanar  gas  is  related  to  the  star  formation surface density. I will present the consequences of our observations for the current accretion in local galaxies, and discuss the implied constraints on the accretion process more generally.

description: Non-charge based logic in single-hole spin of semiconductor quantum dots (QDs) can be controlled by anisotropic gate potentials providing a notion for making next generation solid-state quantum devices. In this study, we investigate the isotropic and anisotropic behavior of phonon mediated spin relaxation of heavy-hole spin hot spots in QDs. For the electron spin in isotropic QDs, hot spots are known to be always present due to the Rashba spin-orbit coupling. But for heavy holes in isotropic dots, we show that the occurrences of spin hot spots are sensitive to the bulk g-factor. The hot spot for Rashba coupling in InAs and GaSb dots arises because these materials possess negative bulk g-factor, while that for the Dresselhaus coupling in GaAs and InSb dots is found due to their positive bulk g-factor. For anisotropic QDs, on the other hand, the spin hot spot is universally present due to their broken in-plane rotational symmetry. Further, the increasing electric field, that strengthens the Rashba coupling, is shown to cover a wide range of magnetic field by the hot spots. Results demonstrate that the magnetic field, choice of dot materials and size anisotropy can act as effective control parameters which can be experimentally used to design the device for detecting the phonon mediated heavy-hole spin-relaxation behavior of III-V semiconductor QDs.

description: For individuals with alternative academic careers, obtaining the skill set necessary to keep collaborative projects afloat and headed in the right direction is essential. Alternative academic careers are often made or broken on the success or failure of such collaborative projects. Success can mean a path to additional funding opportunities and, sometimes, increased institutional security. Project failure can mean unemployment at the end of a term contract. Unfortunately, most people with graduate degrees in the humanities have no explicit or formal preparation in managing collaborative projects, large or small. Given this situation, as a community, alternative academics must consider more concrete methods for transmitting good project management skills and techniques to potential employees. This essay will offer some thoughts on effective project management, effective project managers, and some ways that we might transform graduate education in the humanities to convey more of these necessary skills.
The Morphology And Kinematics Of Neutral Hydrogen In The Vicinity Of Z=0 Galaxies With Milky-Way Masses – A Study With The Illustris Simulation

description: We  analyze  the  properties  of  the  circumgalactic  gas  (CGM)  around  120 galaxies with stellar and dark matter halo masses similar to that of the Milky Way.  We  focus  on  the  morphology  and  kinematics  of  the  neutral  hydrogen component  of  the  CGM  and  how  this  depends  on  the  ratio  of  gas-to-stellar mass  within  the  optical  radius.  In  gas-rich  galaxies,  gas  temperatures  rise monotonically from center of the halo out to the virial radius. Average neutral gas column densities remain higher than 10**19 atoms cm−2 all the way from the center of the galaxy out to radii of 50-70 kpc. In gas-poor galaxies with fg < 0.1, gas temperatures remain fixed at ~10^6 K from the edge of the disk out to  radii  of  100  kpc.  The  column  density  of  neutral  gas  drops  below  1019 atoms  cm−2  at  radii  of  10  kpc.  The  neutral  gas  distributions  are  also more asymmetric in gas-poor galaxies. Most of these trends can be explained by  the  fact  that  in  the  Illustris  simulation,  gas-poor  galaxies  with  Milky  Way masses have massive (108Mo) black holes that accrete at few percent of Eddington, and that energy is being dumped into the halo at large (100 kpc) radii in the form of bubbles of hot gas in these systems. We also find that the circumgalactic  gas  rotates  coherently  about  the  center  of  the  galaxy  with  a maximum  rotational  velocity  of  around  200  km/s.  In  gas-rich  galaxies,  the average coherence length of the rotating gas is 40 kpc, compared to 10 kpc in gas-poor  galaxies.  In  the  most  gas-rich  systems,  the  CGM  can  rotate coherently over scales of 70-100 kpc. We discuss our results in the context of recent observations of the CGM in low mass galaxies via UV absorption-line spectroscopy and deep 21cm observations of edge-on spiral galaxies.

description: Abstract

This research is motivated by the conditions of the implementation of the death penalty in Indonesia, if we look at the practical order, there are still various problems related to the phenomenon of the delay in the implementation of the death penalty for so long and without any legal certainty which of course must be improved immediately, especially in terms of the time of execution or implementation of the death penalty. This study aims to discuss the basic idea of the implementation of the death penalty, the causes of the waiting period in the implementation of the death penalty, and the steps of the prosecutor's office in realizing legal certainty in the implementation of the death penalty. This research is a type of normative legal research or doctrinal research using the Legislative, Conceptual, Historical, and Philosophical Approaches which are analyzed using qualitative descriptive legal methods so that the level of synchronization of laws and regulations can be found. This research covers the scope of research that describes, examines and analyzes and finds general legal theories and laws and regulations on the Role of Prosecutors in the Implementation of the Death Penalty in Indonesia. The results of this study indicate that the government can maintain the death penalty in the Criminal Code to provide a higher preventive effect from disturbances to legal order. Several reasons that can be the cause of the waiting period in the implementation of the death penalty, namely the prisoner has made a request for the convict while pregnant, clemency and extraordinary legal efforts. The formulation of the probationary period regulated in Article 100 of Law Number 1 of 2023 is part of the government's solution to overcome legal certainty regarding the phenomenon of the waiting period for the death penalty in Indonesia. The suggestion that the author can provide from this study is that there needs to be legal clarity in regulating the waiting period before the death penalty is carried out. When the last legal effort has been implemented, the government must be limited by the maximum time. In addition, we hope that the regulations related to the death penalty need to be moderated with the existence of a new Criminal Code (KUHP) which may be a middle ground for the polemic of the waiting period for the death penalty.
Regularizing stock return covariance matrices via multiple testing of correlations

description: This paper develops a large-scale inference approach for the regularization of stock return covariance matrices. The framework allows for the presence of heavy tails and multivariate GARCH-type effects of unknown form among the stock returns. The approach involves simultaneous testing of all pairwise correlations, followed by setting non-statistically significant elements to zero. This adaptive thresholding is achieved through sign-based Monte Carlo resampling within multiple testing procedures, controlling either the traditional familywise error rate, a generalized familywise error rate, or the false discovery proportion. Subsequent shrinkage ensures that the final covariance matrix estimate is positive definite and well-conditioned while preserving the achieved sparsity. Compared to alternative estimators, this new regularization method demonstrates strong performance in simulation experiments and real portfolio optimization.
title: Measurements of the Opposition Effect in the Visible and Near-Infrared Using an Improvised Imaging Spectropolarimeter

description: Spectropolarimetry is a remote sensing technique that combines both spectral and polarimetric measurements. It is already well-established in the astronomical community as an indispensable tool, permitting characterization of dust clouds and stars, and enhancing observations of planetary bodies. One such noteworthy phenomenon is the opposition effect, wherein a planetary body such as the Moon exhibits a surge in reflected intensity as the phase angle—an angle between the Sun, the Moon, and the observer—decreases to below approximately five degrees. Astronomical and laboratory investigations into the opposition effect reveal that the light of this surge often has a polarized component. The terrestrial remote sensing community is starting to develop an interest in spectropolarimetry. Spectral and polarimetric measurements alone, while useful in their diverse applications, stand to benefit from the added dimensionality that spectropolarimetric measurements provide. Examples of applications that benefit from spectropolarimetric measurement include environmental monitoring, search & rescue, and countering denial and deception techniques. To that end, an improvised imaging spectropolarimeter sensitive in the visible and near-infrared spectrum has been developed by attaching a linear polarization filter to a SOC700 hyperspectral imaging system for use in further development of spectropolarimetric applications. The results of three research objectives are reported upon. First, validation of the operation of the improvised imaging spectropolarimeter and the resulting data calibration and processing techniques, including generating Stokes parameter imagery, is successfully completed. Second, demonstrating that the improvised system is capable of observing the opposition effect in a laboratory setting is also confirmed. Third, the improvised system is used to characterize various materials—including rare earth element oxides and ultra-high performance concrete—in various phase angle geometries, with the intent of determining whether the polarized component of the opposition effect yields sufficient additional information for material detection and identification.

description: Flow estimation plays an important role in the control and navigation of autonomous underwater robots. It is challenging for underwater robots because of the complex and dynamic fluid environment. Scientists and engineers have been making great efforts in improving flow estimation capability of underwater robots over the past years. There are two main methods to sense the flow field: (1) using flow sensors to measure flow fields directly; and (2) assimilating other sensor measurements (e.g, pressure) through flow estimation algorithms to estimate the flow field. Since the existing flow measurement equipment, such as pitometer log, is hulking, research about using on board sensors to do the flow estimation has attracted more and more attention. However, most of these algorithms can only be used for a specified shape of underwater vehicle. This thesis presents a novel flow estimation approach that assimilates distributed pressure measurements through coalescing recursive Bayesian estimation and flow model reduction using proper orthogonal decomposition (POD). The proposed flow estimation approach does not rely on any analytical flow model and is thus applicable to many and various complicated flow fields for arbitrarily shaped underwater robots while most of the existing flow estimation methods apply only to well-structured flow fields with simple robot geometry. This thesis also analyzes and discusses the flow estimation design in terms of reduced order model accuracy, relationship with conventional flow parameters, and distributed senor placement. To demonstrate the effectiveness of the proposed distributed flow estimation approach, two simulation studies, one with a circular-shaped robot and one with a Joukowskifoil- shaped robot, are presented. The application of flow estimation in closed-loop angle-ofattack regulation is also investigated through simulation.
title: Narrative Agents as a Reporting Mechanism for Agent-Based Models

subject: Agent-Based Modeling

description: Agent-Based Modeling (ABM) is an approach for building computer models of social situations where computer agents interact with each other within a computer-generated environment. The agents have limited information and the environment can change, simulating complex situations, and interactions between agents and the environment can result in unexpected “emergent” behaviors. One value of ABMs is that they allow for collection of all details of the characteristics and behavior over time of every individual agent and the environment, theoretically enabling the analysis of micro-level interactions between individuals and within small groups. In practice, however, the volume of raw data generated by each run of a model (thousands of which might be done to test a range of parameters) makes it difficult to identify unusual interactions, and analysis of models ends up being done by aggregating data and reporting overall trends. This thesis explores using computer-generated narratives describing the behavior of an individual agent as an alternate method for evaluating the micro-level behavior of an ABM. In addition, approaches are demonstrated for identifying the agents whose narratives are most worth the time to read.
