description: We present an overview of recent results and developments of the no-core shell model (NCSM), an ab initio approach to the nuclear many-body problem for light nuclei. In this approach, we start from realistic two-nucleon or two- plus three-nucleon interactions. Many-body calculations are performed using a finite harmonic-oscillator (HO) basis. To facilitate convergence for realistic inter-nucleon interactions that generate strong short-range correlations, we derive effective interactions by unitary transformations that are tailored to the HO basis truncation. For soft realistic interactions this might not be necessary. If that is the case, the NCSM calculations are variational. In either case, the ab initio NCSM preserves translational invariance of the nuclear many-body problem. In this review, we, in particular, highlight results obtained with the chiral two- plus three-nucleon interactions. We discuss efforts to extend the applicability of the NCSM to heavier nuclei and larger model spaces using importance-truncation schemes and/or use of effective interactions with a core. We outline an extension of the ab initio NCSM to the description of nuclear reactions by the resonating group method technique. A future direction of the approach, the ab initio NCSM with continuum, which will provide a complete description of nuclei as open systems with coupling of bound and continuum states, is given in the concluding part of the review.

Studies on the biosynthesis of trichothecin
Creators: name: Forrester, James McLeod
Publisher: name: University of British Columbia
Year: 2011

description: The derivation of trichothecin (28) from Ɣ-bisabolene (34) is discussed and the contradictory results of two research groups noted. Radioactive [symbol omitted]-bisabolol (35) was prepared by reaction of radioactive methyl magnesium iodide on ketone (42) which was prepared by a modification of a literature procedure. Thus Diels-Alder addition of isoprene (1) and acrylic acid gave acid (41). The structure of the lactone prepared by treatment of this acid with 98% formic acid is corrected to lactone (64) and not lactone (62). Bromide (38) was prepared by a literature procedure from methyl cyclopropyl ketone (44). Addition of the acid chloride of acid (41) to the Grignard complex of bromide (38) gave ester (70) which on treatment with ethereal methyl lithium solution followed by Jones oxidation gave ketone (42). Radioactive [symbol omitted]-bisabolol (34) was then prepared from ketone (42) by reaction with radioactive methyl magnesium iodide, and fed to Trichothecium roseum. Isolation of trichothecin (28) showed an incorporation of 0.014%. Degradation of trichothecin (28) to trichothecolone (29) showed a significant decrease in radioactivity, the significance of which is then discussed.

description: We perceive programs as single-pass instruction sequences. A single-pass instruction sequence under execution is considered to produce a behaviour to be controlled by some execution environment. Threads as considered in basic thread algebra model such behaviours. We show that all regular threads, i.e. threads that can only be in a finite number of states, can be produced by single-pass instruction sequences without jump instructions if use can be made of Boolean registers. We also show that, in the case where goto instructions are used instead of jump instructions, a bound to the number of labels restricts the expressiveness.

title: The Status of Metric Conversion in Industrial Education Programs in Utah With Recommendations for Statewide Training Programs
Creators: name: Brames, Thomas J.
Publisher: name: Utah State University
Year: 1975

description: The purpose of this study was to obtain information from Industrial Education teachers in Utah concerning their feelings and attitudes toward conversion to the Metric System in the United States and to determine their present familiarity with that system. The study was also designed to identify potential problem areas which would tend to influence educational programs on the Metric System for Industrial Education teachers in Utah.
A select sample of four-hundred twenty-three Industrial Education teachers representing over twenty occupational areas was chosen as the population for the study. Two-hundred ninety-seven usable questionnaires (70.2 per cent) were returned and tabulated as follows 1. the total group of Industrial Education teachers responding to the survey 2. each occupational area was tabulated separately, and 3. each occupational area was compared to the total group of Industrial Education teachers responding to the survey.
The study focused on obtaining answers to the five following questions:
1. How familiar are Industrial Education teachers in Utah with the base units of the Metric System?
2. Which subject area teachers have the least understanding of the base units of the Metric System?
3. Which sources of Metric System information have been of greatest value to Industrial Education teachers as sources of general and teaching information?
4. What types of educational programs would be appropriate for familiarizing Industrial Education teachers with the Metric System?
5. Which type s of metric information are currently being used by Industrial Education teachers in Utah?
The analysis of the data and the basic findings of the study warranted the following conclusions:
1 . Industrial Education teachers in Utah are in need of instruction in various portions of the Metric System of measurement. Electronics teachers as a group, do not need further instruction, since electronic s is already taught using metric terminology and measurement.
2. Woods teachers do not see the necessity for metric measurement in their occupation, nor do they see economic advantages in the conversion.
3. Curriculum guide s in Utah have been of little value to Industrial Education teachers in Utah, as sources of metric information.
4. Most subject area textbooks are not written in Metric terminology and are of little value to Industrial Education teachers as sources of metric information.
5. The Utah State Board of Education needs to provide additional guidance for Industrial Education programs on conversion to the Metric System of measurement.
6. General informational programs on the Metric System as well as specific instruction on the use and application of the Metric System of measurement are needed by Industrial Education teachers in Utah.

description: Given an oriented graph G, the modular flow polynomial counts the number of nowhere-zero Z_k-flows of G. We give a description of the modular flow polynomial in terms of (open) Ehrhart polynomials of lattice polytopes. Using Ehrhart-Macdonald reciprocity we give a combinatorial interpretation for the values of the modular flow polynomial at negative arguments which answers a question of Beck and Zaslavsky (2006). Our construction extends to Z_l-tensions and we recover Stanley's reciprocity theorem for the chromatic polynomial. Combining the combinatorial reciprocity statements for flows and tensions, we give an enumerative interpretation for positive evaluations of the Tutte polynomial of G.

title: Student Perceptions of the Environment at Utah State University
Creators: name: Cahoon, Clifford R.
Publisher: name: Utah State University
Year: 1975

description: The environment of Utah State University was studied by administering the College and University Environment Scales (CUES) to 299 sophomore, junior and senior students enrolled spring quarter 1975.
Scores on each scale for the university were: Practicality, 18; Scholarship, 17; Community, 19; Awareness, 22; and Propriety, 12. These figures indicate that USU has an environment which is not scholastically oriented but is open and free allowing students to develop and mature as individuals.
Differences between men and women and between in-state and out-of-state respondents were compared. Women tend to rate the university higher than men in scholarship, community, awareness and practicality and lower in propriety. In-state students rate it higher in scholarship, awareness and community than out-of-state students but lower in practicality and propriety.
The results back up the contention of C. R. Pace, author of CUES, that-women see a university in a better light than men. The difference between in-state student perceptions and out-of-state student perceptions are more difficult to analyze. Looking at the total response to the instrument, it appears that out-of-·state students have a strong reaction to the culture of Utah and react negatively to much of the behavior they see.

description: An N.M.R. study of the clathrate hydrates of SF₆, C₃H₆ and (CH₃)₂CO has been carried out to examine the type of motion a guest molecule undergoes in the clathrated cavity. ¹⁹F nuclear magnetic resonance spectra of Sulphur Hexafluoride Hydrate and Deuterate show isotropic rotation or reorientation about an axis at random of the SF₆molecule. ¹H magnetic resonance spectra of Cyclopropane Deuterate show highly restricted rotation up to 240°K, and then free rotation about C₃-axis at high temperatures. ¹H magnetic resonance spectra of Acetone Deuterate show that the CH₃-group is rotating even at 77°K, and self diffusion occurs at 172°K. The barrier hindering diffusion of the (CH₃)₂CO has been calculated and is 3.9 kcal/mole.
title: The Incidence of Child Abuse and Neglect in the Population at the Utah State Industrial School
Creators: name: Clark, Jeff
Publisher: name: Utah State University
Year: 1976

description: There has been some speculation that abuse/neglect may lead to later antisocial behavior by the abused/neglected child. It was the purpose of this project to determine the frequency of abuse/neglect in the population at the State Industrial School and to compare the types of crimes committed by abused/neglected delinquents with those delinquents not abused/neglected.
The subjects consisted of all the adolescents committed to the State Industrial School. During the research project, 159 adolescents were at the State Industrial School. Of those, 63 had data in their files indicating some form of abuse or neglect.
The findings of the study showed that significantly more abused/neglected delinquents commit authority protest crimes than other categories of crimes. Also, significantly more abused/neglected adolescents are found at the State Industrial School than those not abused/ neglected.
Weak Field Black Hole Formation in Asymptotically AdS Spacetimes

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We use the AdS/CFT correspondence to study the thermalization of a strongly coupled conformal field theory that is forced out of its vacuum by a source that couples to a marginal operator. The source is taken to be of small amplitude and finite duration, but is otherwise an arbitrary function of time. When the field theory lives on $R^{d-1,1}$, the source sets up a translationally invariant wave in the dual gravitational description. This wave propagates radially inwards in $AdS_{d+1}$ space and collapses to form a black brane. Outside its horizon the bulk spacetime for this collapse process may systematically be constructed in an expansion in the amplitude of the source function, and takes the Vaidya form at leading order in the source amplitude. This solution is dual to a remarkably rapid and intriguingly scale dependent thermalization process in the field theory. When the field theory lives on a sphere the resultant wave either slowly scatters into a thermal gas (dual to a glueball type phase in the boundary theory) or rapidly collapses into a black hole (dual to a plasma type phase in the field theory) depending on the time scale and amplitude of the source function. The transition between these two behaviors is sharp and can be tuned to the Choptuik scaling solution in $R^{d,1}$.

description: Aims. We investigate observations of the X-ray binary Cygnus X-1 with unusually high hardness and low flux. In particular, we study the characteristic frequencies seen in the PDS and the hardness-flux correlation within and between these observations. Methods. We analyse observations of Cyg X-1 during periods when the source reaches its highest hardness levels (> 1 for the 9-20 keV over 2-4 keV RXTE/PCA count ratios, corresponding to Gamma < 1.6). Using the relativistic precession model to interpret the PDS we estimate a value for the inner radius of the accretion disc. We also study the hardness-flux correlation. Results. In the selected observations, the characteristic frequencies seen in the power spectrum are shifted to the lowest end of their frequency range. Within a single observation, the hardness-flux correlation is very weak, contrary to the negative correlation normally observed in the hard state. We suggest that this could be interpreted as the inner disc boundary being at large radii (> 50 Rg), thereby requiring more time to adjust to a changing accretion rate than allowed by a single RXTE observation, and compare our findings to estimates of the viscous time scale responsible for small scale variability in the system.

title: “Touched by Time”: Geopolitical Themes of Estonian National Identity through Song Festivals
Creators: name: Hoggard, Mandy L.
Publisher: name: Utah State University
Year: 2016

description: Estonian national identity is defined by its centuries-long struggle forindependence and autonomy. This thesis examines this struggle and resulting identity through the lens of the laulupidu, or song festival, and its employment as a vehicle of political mobilization and re-constructor of Estonian history. Regarding folklore, in this case festivals and folk songs, as containers of the soul of the nation, I show how Estonians have produced and reproduced their national identity through the practice which they hold sacred: choral singing. I implemented a critical geopolitical approach coupled with Billig’s concepts of ‘hot’ and banal nationalism, and Paasi’s focus on independence, to study the 2014 song festival, entitled “Touched by Time. The Time to Touch.” Utilizing the song selection from the 2014 festival and comparing it against the programs from festivals ranging from 1869-2009 (from which selections were gleaned for the 2014 event), this thesis shows how Estonian national identity and historical memory are reconstructed through the symbolic choice of song.

The non-linear corrections result in shifts in the positions of the maximum, minima and nodes of the spectrum within the range of Baryon Acoustic Oscillations. These can be used in order to distinguish theories with different late-time variability of the equation of state.

title: Considering the Crossroads of Distance Education: The Experiences of Instructors as They Transitioned to Online or Blended Courses
Creators: name: Hoffman, David D.
Publisher: name: Utah State University
Year: 2016

description: In the short history of online education research, researchers studying teacher experiences regularly relied on anecdotal examples or small samples. This research sought to support and enhance previous findings concerning the best practices in online education through a nationwide survey of online and blended course instructors. The survey inquired about demographics (such as age, race, and gender), professional position(i.e. tenured professor), institution, department, and their initial and current feelings about teaching online education. It questioned if the respondents studied online as students,what resources administrators provided, their audience, length of instructional experience, and personal behaviors such as blogging or using social media. It also asked what they would want administrators to know, all with the intent to verify current beliefs about the best practices, discover additional possibilities, and find practices,demographics, and behaviors that may be associated or correlated with positive or negative experiences in online education. The study did not acquire enough responses to make generalizable statistical conclusions to the population of online instructors at the top higher educational institutions of the United States, yet the findings supported many of the established best practices in online education: establishing teacher presence, choosing the best content, establishing supportive class communities with interactive social activities, using variety, communicating expectations with students, beginning with clearly defined learning outcomes, making the course materials easily accessible and navigable for students, and emulating the best classroom pedagogies while acknowledging and adjusting for the differences. It also revealed six primary factors the participants felt impacted their positive or negative experiences in online learning: (a) the instructor’s impressions that they/the course succeeded or failed; (b) the quality or lack thereof of student responses and learning; (c) the amount of interaction with students in the course; (d) the perceived availability or unavailability of effective, helpful, and timely support from the institution, colleagues, and IT/technical department; (e) the level of reliability, ease-of-use, and functionality of the LMS or software; and (f) the attitude of the instructor about the medium, including the freedom of design and creation;Additionally, it revealed some instructor concerns about fair compensation for time and effort, particularly when beginning online instruction.

description: The decade-old formulation of the isolated horizon classically and within loop quantum gravity, and the extraction of the microcanonical entropy of such a horizon from this formulation, is reviewed, in view of recent renewed interest. There are two main approaches to this problem: one employs an SU(2) Chern-Simons theory describing the isolated horizon degrees of freedom, while the other uses a reduced U(1) Chern-Simons theory obtained from the SU(2) theory, with appropriate constraints imposed on the spectrum of boundary states `living' on the horizon. It is shown that both these ways lead to the same infinite series asymptotic in horizon area for the microcanonical entropy of an isolated horizon. The leading area term is followed by an unambiguous correction term logarithmic in area with a coefficient $-\frac32$, with subleading corrections dropping off as inverse powers of the area.

title: Examining the Utah 4-H Volunteer Program: The Effects of Donation and Motives in Relation to Volunteer Recruitment and Retention
Creators: name: Romney, Kelsey W.
Publisher: name: Utah State University
Year: 2016

description: Identifying the motivating factors for recruitment and retention of volunteers who are currently enrolled in Utah 4-H is essential to the maintenance of a successful program. This study aimed to determine if there were any specific volunteer motivators related to retention and recruitment and how those motivators related to the cultural demographics of Utah volunteers. Data were collected from 4-H volunteers across the state of Utah to gather baseline information about demographics and motivations. Results indicated that religious affiliation was not a strong indicator of volunteer recruitment but served as a strong motivator toward volunteer retention. The underlying motive of the 4-H volunteers, related to all types of involvement in the program, was an altruistic desire to help others.

description: The strong unique continuation property for Einstein metrics can be concluded from the well-known fact that Einstein metrics are analytic in geodesic normal coordinates. Here we give a proof of the same result that given two Einstein metrics with the same Ricci curvature on a fixed manifold, if they agree to infinite order around a point, then they must coincide, up to a local diffeomorphism, in a neighborhood of the point. The novelty of our method lies in the use of a Carleman inequality and thus circumventing the use of analyticity; thus the method is robust under certain non-analytic perturbations. As an example, we also show the strong unique continuation property for the Riemannian Einstein-scalar-field system with cosmological constant.

title: Exploiting Self-Organization in Bioengineered Systems: A Computational Approach
Creators: name: Davis, Delin
Publisher: name: Utah State University
Year: 2016

description: The productivity of bioengineered cell factories is limited by inefficiencies in nutrient delivery and waste and product removal. Current solution approaches explore changes in the physical configurations of the bioreactors. This work studies the possibilities of exploiting self-organizing vascular networks to support producer cells within the factory. A computational model simulates de novo vascular development of endothelial-like cells and the resultant network functioning to deliver nutrients and extract product from the cell culture. Microbial factories with vascular networks are evaluated for their scalability, robustness, and productivity compared to the cell factories without a vascular network. Initial studies demonstrate at least an order of magnitude increase in production is possible; the system can be scaled up, and that the self-organization of the efficient vascular network is robust. The work suggests that bioengineered multicellularity may offer efficiency improvements difficult to achieve with physical engineering approaches.
Climate change and a range-extending sea urchin : catastrophic-shifts and resilience in a temperate reef ecosystem
Creators: name: Ling, Scott
Publisher: name: University Of Tasmania
Year: 2023

description: The barrens-forming sea urchin Centrostephanus rodgersii (Diadematidae) has undergone recent poleward range-extension to eastern Tasmania. This thesis examines multiple processes influencing the shift from seaweed beds to sea urchin barrens and integrates the findings within the conceptual framework of catastrophic-shifts between the alternative reef states. This thesis identifies two processes acting to alter this temperate reef system: 1. Climate change - resulting in the poleward migration of a habitat-modifying species; and 2. Fishing - resulting in reduced ecosystem resilience. Examination of C. rodgersii population dynamics across the extension-region reveals that recent warming has led to a coastal regime where sea temperature is now suitable for C. rodgersii larval development. Furthermore, the timing of the sea urchins' arrival, age-structure and spatial distribution across the extension-region is consistent with patterns in sea temperature and dispersal potential driven by the EAC. As in the species historic range, C. rodgersii in eastern Tasmania is now found in association with barrens habitat; and field experimentation reveals that creation of barrens by this sea urchin results in local biodiversity loss in the order of ‚ÄövÑvÆ150 taxa that associate with Tasmanian seaweed beds. Furthermore, seaweed-sea urchin dynamics are observed to be broadly consistent with that observed from within the sea urchins' historical range, suggesting that the ecological importance of C. rodgersii will be similar across the extension-region. Field experiments identify the spiny lobster (Palinuridae) as the chief predator of C. rodgersii within the extension-region and trials inside/ outside Marine Protected Areas (where size and abundance of lobsters has recovered following cessation of fishing) demonstrate that C. rodgersii survival rates are decreased in the presence of large predatory lobsters. Indeed, the predatory interaction between lobsters and C. rodgersii is highly size-specific with only lobsters well above the harvested size-limit physically capable of predating on C. rodgersii. Importantly, such predatory capable lobsters have been functionally extirpated from much of the Tasmanian coastline due to intensive fishing for well over a century. The culmination of this thesis is that fishing, by removing large predators, equates to a reduction in ecosystem resilience and increased risk of catastrophic-shift in the face of changing climate.
title: An Examination of How Qualitatively Different Delayed Outcomes are Discounted
Creators: name: Friedel, Jonathan E.
Publisher: name: Utah State University
Year: 2016

description: Delay discounting is the process by which delayed outcomes lose value. Different types of delayed outcomes (e.g., food and money) lose value to different degrees. Higher degrees of delay discounting are related to a wide variety of psychosocial maladies. Chapter I provides context for the studies described in Chapters II-IV. Specifically, cigarette smokers routinely discount delayed money to a greater degree than nonsmokers. Chapters II and III explore the generality of the relation between cigarette smoking and delay discounting by examining how different types of delayed outcomes are discounted. The data presented in these chapters indicate that smokers show a pervasive tendency to steeply discount various types of outcomes when compared to nonsmokers. Across both smokers and nonsmokers, the degree to which a person discounts one delayed outcome is correlated with how they will discount other outcomes. The additive utility model is a recently proposed model of delay discounting that provides potential mechanisms of delay discounting to explain the findings of Chapters II and III. Chapter IV describes the results of empirical test of the additive utility model as it relates to qualitatively different delayed outcomes. In this study, the additive utility model described delay discounting data as well as a more standard model of delay discounting, the hyperbolic model. This study provides tentative support for the additive utility model of delay discounting as an explanatory model. Finally, Chapter V provides a summary of all three studies.

An examination of the frequency of dissociation in traumatic grief
Creators: name: Lum, GB

description: The study and treatment of pathological grief occurs in an environment in which there is no agreed set of criteria for pathological grief. The primary aim of this thesis is to determine whether or not a relationship exists between Traumatic Grief (TG), dissociation, and general psychological distress. The purpose of this study is to investigate if dissociation is more frequent in those bereaved that meet criteria for TG compared to those bereaved who do not. It also aims to establish if those bereaved with a history of traumatic life events dissociate more frequently and report greater general psychological distress than those with no history or with a history of lesser stressful life events. Participants who experienced bereavement were recruited from a newspaper article, self help groups, bereavement counselling services and first year psychology lectures. On the basis of their scores on the Inventory of Traumatic Grief and the Posttraumatic Stress Diagnostic Scale, 49 participants were divided into one of three clinical groups labelled Control, PTSD (Posttraumatic Stress Disorder) and TG+PTSD (Traumatic Grief and Posttraumatic Stress Disorder). The frequency of dissociative experiences, level of general psychological distress and degree of traumatic life experiences were measured from their responses to the Dissociative Experiences Scale, the General Health Questionnaire-28 and the Stressful Life Events Screening Questionnaire respectively. The findings showed that dissociative frequency and general psychological distress were found to be significantly greater in those who met symptom criteria for TG+PTSD. General psychological distress was also found to be greater in those who only met the symptom criteria for PTSD. No significant differences in the kind and quality of experiences of traumatic life events were found between the clinical groups, although the PTSD group showed a trend towards experiencing a greater severity of traumatic life events than did the Control. It was found that a history of multiple traumatic life events was associated with an increase in dissociative frequency and PTSD symptom severity. No association was found between the number of traumatic life events reported by participants and their level of general psychological distress. It is concluded that those with TG, when compared with other bereaved persons, have significantly more dissociative experiences. The results also indicate that dissociation and the severity of PTSD symptoms in the bereaved, is associated with a history of multiple, interpersonal traumatic life events. The findings of this thesis suggest that TG and PTSD may stem from the same psychological construct.
Studies on the afterglow of nitrogen and oxygen discharges

description: The reactions: [formulae omitted] have been studied here in a discharge flow system. Using two temperatures, the rate constant for wall deactivation was found to be 3.8 x 10² exp [fomula omitted] sec⁻¹. It was concluded that the deactivation was not diffusion controlled as previously suggested but controlled by the surface deactivation process on the walls. The rate constant for production of O₂(¹Σg＊) was found to be 6.7 x 10⁴ exp [formula omitted] litres mole⁻¹sec⁻¹, in reasonable agreement with the room temperature value determined by Arnold. An upper limit of 1.6 x 10⁴ litres mole⁻¹sec⁻¹ was obtained for the rate constant of the reaction: N + O₂ (¹Δg ) → NO + 0 showing that the reaction is considerably slower than expected from comparison with the analogous reaction of ground state oxygen. This is rationalized by showing that the two reactions require different transition states. Whilst studying the above reaction several surface catalysed glows from molecular nitrogen and nitric oxide were seen. These glows were found to require O₂ (¹Δg) for their production and not atomic oxygen as previously thought. Several qualitative and spectroscopic experiments were performed and in the light of the information gained various possible mechanisms are discussed.
The DODO Survey II: A Gemini Direct Imaging Search for Substellar and Planetary Mass Companions around Nearby Equatorial and Northern Hemisphere White Dwarfs

description: The aim of the Degenerate Objects around Degenerate Objects (DODO) survey is to search for very low mass brown dwarfs and extrasolar planets in wide orbits around white dwarfs via direct imaging. The direct detection of such companions would allow the spectroscopic investigation of objects with temperatures much lower (< 500 K) than the coolest brown dwarfs currently observed. These ultra-low mass substellar objects would have spectral types > T8.5 and so could belong to the proposed Y dwarf spectral sequence. The detection of a planet around a white dwarf would prove that such objects can survive the final stages of stellar evolution and place constraints on the frequency of planetary systems around their progenitors (with masses between 1.5 - 8 solar masses, i.e., early B to mid F). This paper presents the results of a multi-epoch J band common proper motion survey of 23 nearby equatorial and northern hemisphere white dwarfs. We rule out the presence of any common proper motion companions, with limiting masses determined from the completeness limit of each observation, to 18 white dwarfs. For the remaining five targets, the motion of the white dwarf is not sufficiently separated from the non-moving background objects in each field. These targets require additional observations to conclusively rule out the presence of any common proper motion companions. From our completeness limits, we tentatively suggest that < 5% of white dwarfs have substellar companions with effective temperatures > 500 K between projected physical separations of 60 - 200 AU.

Single-neutron excitations in A=135 nuclei
Creators: name: Ummel, Chad Conrad
Publisher: name: No Publisher Supplied
Year: 2023

description: The nuclear shell model is the foundational model of nuclear physics. It predicts single-particle and single-hole states above and below closed neutron and proton shells. Experimental measurements of nuclei near the shell closures yield important information on the evolution of nuclear structure away from stability and serve as empirical inputs for improved shell model calculations. In particular, neutron-transfer reactions can be used to probe the the single-neutron states of nuclei near the shell closures. 135Xe (Z=54, N=81) lies just one neutron below the N=82 closed shell. Using the (d,p) reaction on 134Xe, single-particle excitations of the unpaired 81st neutron in 135Xe were observed. This 134Xe(d,pg)135Xe measurement was performed at the ATLAS accelerator facility at Argonne National Laboratory, where the coupled GODDESS (Gammasphere-ORRUBA: Dual Detectors for Experimental Structure Studies) detectors were used to detect reaction protons and decay gamma rays in coincidence. This coincident measurement resulted in the identification of five previously unobserved single-neutron levels in 135Xe.
Minimal sets of non-resonant torus homeomorphisms

description: As was known to H. Poincare, an orientation preserving circle homeomorphism without periodic points is either minimal or has no dense orbits, and every orbit accumulates on the unique minimal set. In the first case the minimal set is the circle, in the latter case a Cantor set. In this paper we study a two-dimensional analogue of this classical result: we classify the minimal sets of non-resonant torus homeomorphisms; that is, torus homeomorphisms isotopic to the identity for which the rotation set is a point with rationally independent irrational coordinates.

description: In 1864,Waage and Guldberg formulated the "law of mass action." Since that time, chemists, chemical engineers, physicists and mathematicians have amassed a great deal of knowledge on the topic. In our view, sufficient understanding has been acquired to warrant a formal mathematical consolidation. A major goal of this consolidation is to solidify the mathematical foundations of mass action chemistry -- to provide precise definitions, elucidate what can now be proved, and indicate what is only conjectured. In addition, we believe that the law of mass action is of intrinsic mathematical interest and should be made available in a form that might transcend its application to chemistry alone. We present the law of mass action in the context of a dynamical theory of sets of binomials over the complex numbers.

Assessing the validity of two measures of psychopathy in an Australian undergraduate sample
Creators: name: McBain, Allison
Publisher: name: University Of Tasmania
Year: 2023

description: Psychopathy is a personality construct that holds a prominent position in psychology and psychiatry, particularly within forensic psychology. The aim of the present paper is to provide a review of the historical and theoretical conceptualisation of psychopathy and to evaluate the development and use of psychopathy assessment measures. A brief review of research findings into the relationship between psychopathy and criminality is presented as a means of highlighting the importance of the psychopathy construct particularly the implications it holds for mental health services and forensic services, as well as the general community. The present paper will also review the current criticisms relating to psychopathy research, in particular, around lack of research into noncriminal psychopathy and sex differences between the occurrences of psychopathy. Finally a discussion of the use of self-report measures for assessing noncriminal psychopathy will occur, focusing specifically on two measures; the Self-Report Psychopathy Scale ‚ÄövÑvÆ III and the Psychopathic Personality Inventory ‚ÄövÑvÆ Revised.
