title: Investigation of Concrete Electrical Resistivity As a Performance Based Test
Creators: name: Malakooti, Amir
Publisher: name: Utah State University
Year: 2017

description: The purpose of this research project was to identify the extent that concrete resistivity measurements (bulk and/or surface) can be used as a performance based lab test to improve the quality of concrete in Utah bridge decks. By allowing UDOT to specify a required resistivity, concrete bridge deck quality will increase and future maintenance costs will decrease.
This research consisted of two phases: the field phase and the lab phase. In the field phase, concrete samples were gathered from local concrete producers in Utah. These concrete samples were made with common concrete mixes used in bridge decks across the state of Utah. Testing multiple mix designs allowed the research team to investigate several variations of concrete constituents, for instance, water to cement ratio, common Utah supplementary cementitious materials, curing type, and aggregate type. Mechanical and durability testing was performed on concrete of different ages. These tests included strength, surface resistivity, bulk resistivity, rapid chloride permeability, and freeze and thaw tests.
In the lab phase, one of the field mixes was selected as the control mix. This mix was then duplicated in the lab in order to see the performance differences of each mix in the controlled and field experiments. In addition, changes were made to the lab control mix, to see the effect of different materials on the resistivity and durability of concrete.
title: Rancher Perceptions of Ecosystem Services from Rangelands of the Intermountain West
Creators: name: York, Elisabeth C.
Publisher: name: Utah State University
Year: 2017

description: Rangelands within the Great Basin are responsible for the provision of multiple resources that humans depend on for a variety of reasons. Ranchers in this region are dependent on public lands to remain economically viable in their cattle operations. As a majority of land in this region is publically owned, there are varying interests at play in what should and could be the focus of management. Ranchers are charged with implementing strategies aimed at conserving these landscapes and their motivations for what to manage may significantly influence resource provision from Intermountain West ecosystem.
In this study, I sought to understand what resources ranchers manage and why ranchers manage for certain resources. I also sought to understand operational characteristics which allow or inhibit them from managing for a suite of resources. My study population was ranchers throughout the Intermountain West who depend on public lands to graze their cattle. I utilized interviews as well as mail-in surveys to broadly understand what ranchers value about rangelands. From both qualitative and quantitative data, I found that ranchers make management decisions to encourage productivity, maintain a ranching legacy and remain autonomous in their operation. Managing to encourage these three ideals could ensure that their operations remain viable for their family in the future. I also found that based on size of operation, how active ranchers are on their operation, and how income dependent they are on their operation contribute to managing for more and a certain type of resource.
Overall, this research was designed to encourage management for a suite of resources on rangeland landscapes. Ranchers seem to manage most highly for resources directly beneficial to their operation. By educating and incentivizing ranchers to manage more broadly for resources that benefit a broader public on public lands which we all hold claim to, resilience of both human communities as well as the ecosystem itself will be enhanced.
title: The Influence of Varying Fiber Stacking Sequence on the Tensile, Impact, and Water Absorption Properties of Unidirectional Flax/E-Glass Fiber Reinforced Epoxy Composite
Creators: name: Al-Edhari, Mohammed F.
Publisher: name: Utah State University
Year: 2017

description: This thesis includes the study of the mechanical performance of two different types of fibers reinforced hybrid composites. Two kinds of fibers, natural fiber (flax) and synthetic fiber (E-glass), are used to reinforce epoxy resin. To evaluate the effective properties of the hybrid composites, a micromechanical analysis of the structure genome (SG) of a unidirectional fiber hybrid composites is performed using nite element analysis (FEA). Both fibers are assumed to be circular and packed in a hexagonal pattern. The effects of varying volume fractions and fiber locations, of the two fibers, on the elastic properties of the hybrid composites are studied using FEA. Rule of hybrid mixtures (RoHM) and Halpin-Tsai equations, which are analytical equations, are used as a preliminary prediction of the elastic constants of the hybrid composites. Then, the comparison is made between FEA and analytical results. The predicted elastic constants through numerical homogenization are in good a agreement with analytical results. The effect of changing fiber locations on the tensile strength of hybrid composite is investigated using tensile tests. Impact strength of single fiber composites and ax/glass fiber hybrid composites, in which various stacking sequences of ax and glass fibers are used, are obtained using Charpy impact tests. Moisture absorption test was performed by immersing single fiber composites and various stacking sequences of hybrid composites in deionized water at room temperature for a week. To investigate the effect of water absorption on the tensile properties of composite, tensile test was done on various stacking sequences of the hybrid composite. FEA and analytical equations showed that Young's and shear moduli increased and the axial Poison's ratio decreased linearly with the glass fiber content. Also, FEA showed that changing fiber locations have no effect on the effective properties of the hybrid composite. However, changing fiber stacking sequences showed a significant effect on tensile strength, impact strength, and water absorption properties of the hybrid composites. It was concluded that better design of the hybrid composite was achieved when glass fibers placed on the extreme positions and flax fibers in the middle. Positive hybrid effect is achieved from hybridization of E-glass fiber with flax fiber.

description: Protein solubilization for two-dimensional electrophoresis (2DE) has to break molecular interactions to separate the biological contents of the material of interest into isolated and intact polypeptides. This must be carried out in conditions compatible with the first dimension of 2DE, namely isoelectric focusing. In addition, the extraction process must enable easy removal of any nonprotein component interfering with the isoelectric focusing. The constraints brought in this process by the peculiar features of isoelectric focusing are discussed, as well as their consequences in terms of possible solutions and limits for the solubilization process.

description: Oppositely charged drops have long been assumed to experience an attractive force that favors their coalescence. In this fluid dynamics video we demonstrate the existence of a critical field strength above which oppositely charged drops do not coalesce. We observe that appropriately positioned and oppositely charged drops migrate towards one another in an applied electric field; but whereas the drops coalesce as expected at low field strengths, they are repelled from one another after contact at higher field strengths. Qualitatively, the drops appear to `bounce' off one another. We directly image the transient formation of a meniscus bridge between the bouncing drops.

title: Exploring the Relationship Between the Use of a Selected Phonics Curriculum and the Oral Reading Fluency and Nonsense Word Fluency Scores of First-grade Students
Creators: name: Day, Bryce B.
Publisher: name: Utah State University
Year: 2017

description: The purpose of this quantitative study was to examine the effects, if any, of a supplemental phonics curriculum, Saxon Phonics, on the reading achievement of first-grade students in one mountain-west, semirural, school district. The design was casual-comparative and ex post facto, and answered the questions: (1) Do students taught using a traditional basal program and students taught using both the traditional basal program and a supplemental phonics program (control vs. treatment) differ on selected end-of-year reading achievement scores (i.e., portions of the DIBELS Next assessment—nonsense word fluency [NWF], oral reading fluency [ORF], and accuracy [ACC])? (2) do any possible interactions among selected variables (i.e., instructional program, gender, and beginning-of-year reading level) exist related to performance differences on end-of-year reading achievement scores among students receiving reading instruction with or without a supplemental phonics program? The independent variables were the instructional program Saxon Phonics, a traditional/basal reading curriculum and the reading levels of low, medium, and high. The dependent variables were oral reading fluency, accuracy and nonsense word fluency, measured by the DIBELS Next assessment. The 2014-2015 and 2015-2016 DIBELS Next data were collected from the school district database upon approval from the Institutional Review Board in January of 2017. A mixed effects model was utilized to explore the relationship between use of the selected supplemental phonics curriculum and selected reading achievement scores of first-grade students. Results revealed that there was no significant difference between the control and treatment groups, though there was a statistically significant improvement of low readers in the treatment group over the control group.

description: During infections, Staphylococcus aureus is exposed to hypochlorous acid (HOCl) and hypothiocyanous acid (HOSCN), which are produced by the neutrophil myeloperoxidase as potent antimicrobial killing agents. In this work, we applied RNAseq transcriptomics, Brx-roGFP2 biosensor measurements, and phenotype analyses to investigate the stress responses and defense mechanisms of S. aureus COL toward HOSCN stress. Based on the RNAseq transcriptome profile, HOSCN exerts strong thiol-specific oxidative, electrophile, and metal stress responses as well as protein damage in S. aureus, which is indicated by the strong induction of the HypR, TetR1, PerR, QsrR, MhqR, CstR, CsoR, CzrA, AgrA, HrcA, and CtsR regulons. Phenotype analyses of various mutants in HOSCN-responsive genes revealed that the HOSCN reductase MerA conferred the highest resistance toward HOSCN stress in S. aureus COL, whereas the QsrR and MhqR electrophile stress regulons do not contribute to protection. Brx-roGFP2 biosensor measurements and bacillithiol (BSH)-specific Western blot analyses revealed a strong oxidative shift of the bacillithiol redox potential (EBSH) and increased S-bacillithiolations in S. aureus, indicating that BSH is oxidized to bacillithiol disulfide (BSSB) under HOSCN stress. While the ΔmerA mutant was delayed in recovery of the reduced EBSH, overproduction of MerA in the ΔhypR mutant enabled faster recovery of EBSH due to efficient HOSCN detoxification. Moreover, both MerA and BSH were shown to contribute to HOSCN resistance in growth assays. In summary, HOSCN provokes a thiol-specific oxidative, electrophile, and metal stress response, an oxidative shift in EBSH and increased S-bacillithiolation in S. aureus.

description: We present both analytically and numerically the consistent analysis from the Affleck-Dine (AD) dynamics to the subsequent semiclassical evolution in both gravity-mediated and gauge-mediated models. We obtain analytically the elliptic motions in the AD dynamics as the analogy of the well-known Kepler-problem, and by solving the equations of motion in a lattice, we find that the semiclassical evolution goes through three distinct stages as a nonequilibrium process of reheating the Universe: pre-thermalisation, bubble collisions and thermalisation. We report that the second stage of our case lasts rather long compared to the second stage of the reheating case, and the thermalisation process is unique due to the presence of ``thermal Q-balls''.

description: Monte Carlo simulations are widely used in nuclear physics to model experimental systems. In cases where there are significant unknown quantities, such as energies of states, an iterative process of simulating and fitting is often required to describe experimental data. We describe a Bayesian approach to fitting experimental data, designed for data from a $^{12}$Be(d,p) reaction measurement, using simulations made with GEANT4. Q-values from the $^{12}$C(d,p) reaction to well-known states in $^{13}$C are compared with simulations using BayesOpt. The energies of the states were not included in the simulation to reproduce the situation for $^{13}$Be where the states are poorly known. Both cases had low statistics and significant resolution broadening owing to large proton energy losses in the solid deuterium target. Excitation energies of the lowest three excited states in $^{13}$C were extracted to better than 90 keV, paving a way for extracting information on $^{13}$Be.

description: We examine the rare decays $B_s\to l^+l^-$ and $B\to Kl^+l^-$ in the framework of the topcolor-assisted technicolor ($TC2$) model. The contributions of the new particles predicted by this model to these rare decay processes are evaluated. We find that the values of their branching ratios are larger than the standard model predictions by one order of magnitude in wide range of the parameter space. The longitudinal polarization asymmetry of leptons in $B_s \to l^+l^-$ can approach $\ord(10^{-2})$. The forward-backward asymmetry of leptons in $B \to Kl^+l^-$ is not large enough to be measured in future experiments. We also give some discussions about the branching ratios and the asymmetry observables related to these rare decay processes in the littlest Higgs model with T-parity.

title: Emotional Experience During Couple Support Interactions: The Role of Attachment Anxiety and Avoidance
Creators: name: Lachmar, E. Megan
Publisher: name: Utah State University
Year: 2017

description: The Marriage and Family Therapy clinic at Utah State University conducted a study called the Relationship Checkup in which couple data was collected in an initial 2-hour session and feedback was provided for them in a follow-up 1-hour session. This checkup included completing self-report surveys, having an in-person interview, as well as couple interactions. The current study was carried out within the context of this broader relationship checkup, focusing on the couple support interactions, in which partners discussed a personal issue they would like to change about themselves.
Although a substantial amount of attention has been given to the role of attachment during couple conflict, much less attention has been given to social support processes. Yet the purpose of therapy is not only to diminish disruptive conflict but also to enhance positive relationship processes, making a greater understanding of social support processes crucial to the therapy process.
The results of this study indicate that partners with higher levels of avoidant attachment perceived they were receiving and providing less support. This reveals that couple therapists may need to assist these partners in reaching out and providing support. Additionally, results show that for women, discussing a personal issue soothed them physiologically. Therefore, rather than focusing on couple conflict, couples therapists can also build positive relationship interactions through couple social support.

description: Silver staining detects proteins after electrophoretic separation on polyacrylamide gels. Its main positive features are its excellent sensitivity (in the low nanogram range) and the use of very simple and cheap equipment and chemicals. The sequential phases of silver staining are protein fixation, then sensitization, then silver impregnation, and finally image development. Several variants of silver staining are described here, which can be completed in a time range from 2 h to 1 day after the end of the electrophoretic separation. Once completed, the stain is stable for several weeks.

description: Fast radio bursts (FRBs) are very energetic pulses of unknown physical origin. These can be used to study the intergalactic medium (IGM) thanks to their dispersion measure (DM). The DM has several contributions that can be measured (or estimated), including the contribution from the host galaxy itself, DM_host. In this work, we empirically estimate DM_host for a sample of 12 galaxy hosts, using a direct method based solely on the properties of the host galaxies themselves (DM_host_dir). We use VLT/MUSE observations of the FRB hosts for estimating DM_host_dir. The method relies on estimating the DM contribution of both the FRB host galaxy's interstellar medium and its halo separately. For comparison purposes, we also provide an alternative indirect method to estimate DM_host based on the Macquart relation (DM_host_mq). We find an average = 80+/-11 pc/cc with a standard deviation of 38 pc/cc (in the rest-frame) based on our direct method, with a systematic uncertainty of 30%. We report positive correlations between DM_host and both the stellar masses and the star-formation rates of their host galaxies. In contrast, we do not find any strong correlation between DM_host and neither redshift nor the projected distances to the FRB hosts centers. Finally, we do not find any strong correlation between DM_host_dir and DM_host_mq, although their average values are consistent. Our reported correlations could be used to improve the priors used in establishing DM_host for individual FRBs. Similarly, such correlations and the lack of a strong redshift evolution can be used to constrain models for the progenitor of FRBs. However, the lack of a DM_host_dir and DM_host_mq correlation indicates that there may still be contributions to the DM of FRBs not included in our modeling, e.g. large DMs from the FRB progenitor and/or intervening large-scale structures not accounted for in DM_host_mq.

description: Uridine diphosphate N-acetylglucosamine 2-epimerase (GNE) is a key enzyme in the sialic acid biosynthesis pathway. Sialic acids are primarily terminal carbohydrates on glycans and play fundamental roles in health and disease. In search of effective GNE inhibitors not based on a carbohydrate scaffold, we performed a high-throughput screening campaign of 68,640 drug-like small molecules against recombinant GNE using a UDP detection assay. We validated nine of the primary actives with an orthogonal real-time NMR assay and verified their IC50 values in the low micromolar to nanomolar range manually. Stability and solubility studies revealed three compounds for further evaluation. Thermal shift assays, analytical size exclusion, and interferometric scattering microscopy demonstrated that the GNE inhibitors acted on the oligomeric state of the protein. Finally, hydrogen-deuterium exchange mass spectrometry (HDX-MS) revealed which sections of GNE were shifted upon the addition of the inhibitors. In summary, we have identified three small molecules as GNE inhibitors with high potency in vitro, which serve as promising candidates to modulate sialic acid biosynthesis in more complex systems.

description: Particle sensing in optical tweezers systems provides information on the position, velocity and force of the specimen particles. The conventional quadrant detection scheme is applied ubiquitously in optical tweezers experiments to quantify these parameters. In this paper we show that quadrant detection is non-optimal for particle sensing in optical tweezers and propose an alternative optimal particle sensing scheme based on spatial homodyne detection. A formalism for particle sensing in terms of transverse spatial modes is developed and numerical simulations of the efficacy of both quadrant and spatial homodyne detection are shown. We demonstrate that an order of magnitude improvement in particle sensing sensitivity can be achieved using spatial homodyne over quadrant detection.

title: Direct Effects of Warming Increase Woody Plant Abundance in a Subarctic Wetland
Creators: name: Carlson, Lindsay G.
Publisher: name: Utah State University
Year: 2017

description: Climate change is expected to continue to cause large increases in temperature in Arctic and sub-Arctic ecosystems which has already resulted in changes to plant communities; for example, increased shrub biomass and range. It is important to understand how warmer temperatures could affect the plant community in a wetland system because this region provides crucial high-quality forage for migratory herbivores during the breeding season. One mechanism by which warming could cause change is directly, where warming influences the vital rates of a species; these effects may be either positive or negative. Warmer temperatures may also affect a species indirectly, by impacting neighboring plants which compete with, or facilitate that species. Altering interspecific interactions may affect the abundances of the surrounding species. Recent research shows these ‘indirect’ effects which are mediated by biotic interactions may be important enough to reverse ‘direct’ effects of climate change in some plant communities. Furthermore, herbivores have been shown to mediate the effects of warming, in some systems, even preventing shrub expansion. However, the abundance of herbivores may change because of climate change so it is important to understand the role of herbivores in mitigating climate change effects to inform management strategy. Therefore, we aimed to determine the importance of direct and indirect effects of warming on this plant community while considering changing herbivore pressures.
We conducted a two-year field experiment in the coastal wetlands of western Alaska to investigate how warming and herbivory will impact the abundances of two common species, a sedge and a dwarf shrub. We used the results from the experiment to predict the equilibrium abundances of the two species under different climate and herbivory scenarios and determine the contribution of direct and indirect effects to predicted community change.
The sedge, Carex ramenskii, remained dominant in under ambient conditions, but the dwarf shrub, Salix ovalifolia, became dominant in warmed treatments. Herbivory mediated some of the effects of warming; where grazing was present community composition did not change as much as where it was not grazed. Results suggest that in the absence of goose herbivory, a 2°C increase could cause a shift from sedge to woody plant dominance on the coast of western Alaska. However, if grazing pressure by geese continues at the present rate, it may help retain the current community composition, though herbivory pressure was not sufficient to entirely reverse the effect of warming. Finally, we found that direct effects were more important than indirect effects in causing changes to this plant community.

description: Commemorating the 60th anniversary of diplomatic ties, the article analyzes public health governance during the COVID-19 pandemic in the EU and South Korea. Shifting focus from traditional national security to a more people-centered understanding, the article employs the human security framework to examine nuances of the global health crisis. Through this theoretical lens, the research empirically compares and contrasts the EU’s and South Korea’s differing strategies battling COVID-19 from the pandemic’s inception to the mass vaccination rollouts. While the EU’s early approach was initially marked by slower responsiveness and border closures, South Korea stood out for its swift counter-epidemic measures, leveraging technological innovations and public–private partnerships. Yet once vaccination campaigns started, South Korea had to catch up with Europe. The article chronologically presents its findings, identifying a mutual convergence in approaches with the Omicron’s emergence. In conclusion, the article distills seven key lessons from the pandemic management: the significance of independent public health institutions, the role of digitalization and transparency in fostering public trust, the shared responsibility to bridge the vaccination gap and invest in robust public health systems, and the paradigm shift towards human security combined with the resurgence of state which has to be balanced with safeguarding individual liberties and a collective global action. In addition, the article underscores potential avenues for a strengthened EU-South Korea collaboration to enhance global health governance beyond the confines of major geopolitical rivalries.

Publisher: name: Utah State University

description: Electric vehicles represent a major accomplishment in the energy and transportation industry. Unfortunately, they are restricted to a small travel range because of limited battery life. Successful integration of wireless power transfer (WPT) systems into the infrastructure would remove the range restrictions of EVs. To successfully integrate this technology, several requirements must be met. First, the embedment process cannot interfere with the electrical performance of the inductive power transfer (IPT) system. Second, the presence of the IPT system in the pavement structure cannot negatively affect the roadway’s lifespan.
Several systems were directly embedded in roadway materials. The electrical properties of the systems were monitored during the embedment process. Then modifications were made to the IPT systems to optimize the embedment process. These modifications were then applied to a full scale IPT system which is being used to dynamically charge EVs.
To test the structural performance of the systems, tensile stresses were applied to the pads to simulate traffic loading conditions. These tensile stresses were applied under cyclic loading conditions to simulate fatigue conditions found in roadways. The number of cycles, and stress at failure was recorded an analyzed. The electrical properties of the IPT pads was also measured and analyzed during the fatigue loading conditions.

description: During the COVID-19 pandemic, a sizable proportion of employees conducted home-based telework to contain virus spreading. This situation made it possible to investigate the relationship between telework and job characteristics. Many positive and negative associations between telework and job characteristics have been proposed in the literature, but most studies relied on cross-sectional data as well as narrow samples (e.g. employees voluntarily choosing to telework). Repeated measures designs investigating the association between telework intensity and job characteristics using less selective samples are currently rare. To address this research gap, we collected data at two time points in Germany during the COVID-19 pandemic (n = 479) and investigated if change in telework intensity was associated with change in 19 job characteristics using structural equation modeling. Our analyses showed that—in contrast to several prior cross-sectional studies—telework intensity had a small to moderate association with only two out of the 19 job characteristics: Work scheduling and decision-making autonomy. Hence, the study challenges the previously assumed manifold positive and negative associations between telework intensity and job characteristics and adds to the debate about the role of telework intensity as an antecedent of work design. Future studies should investigate the generalizability of the findings to non-pandemic work contexts.
Storytelling and Videogames. An interdisciplinary appro- ach to interactive multimedia models for children
Creators: name: Antoniazzi, Anna
Publisher: name: Studi sulla Formazione
Year: 2013

description: Although scientific literature, since long time, underlines the importance of storytelling and games as essential cognitive and educational moments, current studies and researches are largely resting over a separate analysis of games and storytelling, establishing a hierarchy among them which crowns one or the other likewise from time to time. It is therefore necessary developing and tuning up methods and educational model that will allow us to develop the natural attitude of human mind to place all information inside one context and one set.

description: We consider a general anisotropic massive SU(N) fermionic model, and investigate its quantum integrability. In particular, by regularizing singular operator products, we derive a system of equations resulting in the S-matrix and find some non-trivial solutions. We illustrate our findings on the example of a SU(3) model, and show that the Yang-Baxter equation is satisfied in the massless limit for all coupling constants, while in the massive case the solutions are parameterized in terms of the exceptional solutions to the eight-vertex model.

Studies related to the synthesis of bisindole alkaloids of the Indole-Indoline type
Creators: name: Treasurywala, Adi Minoo
Publisher: name: University of British Columbia
Year: 2010

description: The first part of this thesis describes the synthesis of 3,4- functionalized cleavamine templates bearing a C₁₈- carbomethoxy group. Thus hydroboration of 18β-carbomethoxycleavamine (29) produced two epimeric alcohols; 18α- and 18β -carbomethoxydihydrocleavamin -3 -ol (56 and 57). These compounds could be interconverted by using boron trifluoride etherate in benzene. One of these compounds (56) could be oxidized to the corresponding C₃ ketone which is a key intermediate for future work. The second part describes the research in the area of the so-called dimerization reaction. The generality of a procedure which had been used before was tested. When the chloroindolenine of 4(3-dihydrocleavamine and 18-carbomethoxy-43-dihydrocleavamine were each treated with vindoline in 1.5% methanolic hydrogen chloride,good yields of dimeric products were obtained. These materials have been shown by X-ray to be epimeric at C₁₈, to the natural dimers vincristine (VCR) and vinblastine (VLB). When these conditions were applied to the chloro- indolenines of 18β -carbomethoxycleavamine arid the 18α - and 18β -carbomethoxy-cleavaminols (56 and 57),good yields of dimers did not result. A detailed study, which has illuminated the mechanism of this reaction, was thus undertaken. As a result of this study, an improved procedure for the dimerization of such sensitive cleavamine templates was discovered. The insight gained from this study has permitted changes in the reaction conditions which have resulted in the isolation of two dimeric products from a single dimerization reaction. Previously, only one dimer had resulted from such reactions stereoselectively. Several new and exciting other approaches to the coupling of the indole and dihydroindole portions have been explored. Some of these have uncovered novel and useful avenues for eventually achieving the synthesis of the natural dimers such as VLB, VCR leurosine and leurosidine.

description: This article offers initial theorizing on an understudied phenomenon in the workplace: the meeting after the meeting (MATM). As an informal and unscheduled event, the MATM takes place outside managerial control and has potentially far-reaching consequences. However, our current knowledge of the MATM relies primarily on practitioner observations, and conceptual work that integrates the MATM into the larger meeting science literature is missing. This article fills this gap by outlining key defining features of the MATM that can be used to structure future research. Moreover, and based on theorizing concerning the affect-generating nature of meetings, we develop an affect-based process model that focuses on the antecedents and boundary conditions of the MATM at the episodic level and shines light on meetings as a sequential phenomenon.
Supersymmetric Dark Matter Candidates

description: After reviewing the theoretical, phenomenological and experimental motivations for supersymmetric extensions of the Standard Model, we recall that supersymmetric relics from the Big Bang are expected in models that conserve R parity. We then discuss possible supersymmetric dark matter candidates, focusing on the lightest neutralino and the gravitino. In the latter case, the next-to-lightest supersymmetric particle is expected to be long-lived, and possible candidates include spartners of the tau lepton, top quark and neutrino. We then discuss the roles of the renormalization-group equations and electroweak symmetry breaking in delimiting the supersymmetric parameter space. We discuss in particular the constrained minimal extension of the Standard Model (CMSSM), in which the supersymmetry-breaking parameters are assumed to be universal at the grand unification scale, presenting predictions from a frequentist analysis of its parameter space. We also discuss astrophysical and cosmological constraints on gravitino dark matter models, as well as the parameter space of minimal supergravity (mSUGRA) models in which there are extra relations between the trilinear and bilinear supersymmetry-breaking parameters, and between the gravitino and scalar masses. Finally, we discuss models with non-universal supersymmetry-breaking contributions to Higgs masses, and models in which the supersymmetry-breaking parameters are universal at some scale below that of grand unification. http://cambridge.org/us/catalogue/catalogue.asp?isbn=9780521763684

title: A Two Sample Test of the Reliability Performance of Equipment Components
Creators: name: Coleman, Miki Lynne
Publisher: name: Utah State University
Year: 1972

description: The purpose of this study was to develop a test which can be used to compare the reliability performances of two types of equipment components to determine whether or not the new component satisfies a given feasibility criterion.
Two types of tests were presented and compared: the fixed sample size test and the truncated sequential probability ratio test. Both of these tests involve use of a statistic which is approximately distributed as F.
This study showed that the truncated sequential probability ratio test has good potential as a means of comparing two component types to see whether or not the reliability of the new component is at least a certain number of times greater than the reliability of the old component.

Almost 2 years into the COVID-19 pandemic: an update on parental stress, parent mental health, and the occurrence of child maltreatment

description: Increased parental stress, poorer mental health, and an increase in the occurrence of child maltreatment (CM) have been reported in earlier phases of the COVID-19 pandemic. However, data from later phases of the pandemic are not yet available. We conducted a cross-sectional, representative survey among 1087 parents (48.8% female; mean age 41.72 years, SD = 9.15) in Germany in December 2021. Data were compared to a previous representative sample, assessed in August 2020 (N = 1024), and to normative scores of the outcome measures. Predictors for the occurrence of CM were analyzed by logistic regression. Pandemic-related stress and general stress were higher and physical and mental health were poorer in the December 2021 sample than in the August 2020 sample. Occurrence rates of CM varied between 5 and 56%. Verbal emotional abuse (n = 607, 56%), witnessing domestic violence (n = 446, 41%), and emotional neglect (n = 435, 40%) were most frequently reported. For these subtypes, parental risk for alcohol abuse (OR 2.1–2.7) and parental recent experience of violence (OR 2.1–5.1) were the strongest predictors. Across all subtypes of CM, parents reporting child maltreatment showed poorer scores on all stress outcomes, with medium–large-effect sizes. Results confirm a high burden within the families, almost 2 years into the pandemic. Occurrence rates of a broad spectrum of CM subtypes raise further concerns for the well-being of children. Family-oriented intervention efforts are needed to stabilize families and provide targeted support. Longitudinal studies are needed for a description of families at risk for poorer outcomes.
Flickering around the outburst cycle in Kepler dwarf novae

description: Taking advantage of the unparallel quantity and quality of high cadence Kepler light curves of several dwarf novae, the strength of the flickering and the high frequency spectral index of their power spectra are investigated as a function of magnitude around the outburst cycle of these systems. Previous work suggesting that the flickering strength (on a magnitude scale) is practically constant above a given brightness threshold and only rises at fainter magnitudes is confirmed for most of the investigated systems. As a new feature, a hysteresis in the flickering strength is seen in the sense that at the same magnitude level flickering is stronger during decline from outburst than during the rise. A similar hysteresis is also seen in the spectral index. In both cases, it can qualitatively be explained under plausible assumptions within the DIM model for dwarf nova outbursts.
