title: That Hidden Country: The Travels of Jacob Singleton, A Novel
Creators: name: Earp, James
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Thomas Jefferson believed, or wanted to believe, that mammoths foraged the grasslands of the continental American interior. This was not an uncommon belief among the learned in Jefferson’s time and place, so it is not altogether remarkable that Jefferson did charge Meriwether Lewis and William Clark, when they led the Corps of Discovery to the Oregon coast, with keeping an eye out for signs of the living mammoth. This novel attempts an aesthetically viable narrative synthesis of American myths in several layers, the top layer being, in the words of cultural critic Cintra Wilson, a ‘‘ripping yarn’’ in the traditions of Alexander Dumas, James Fenimore Cooper, Jules Verne, Arthur Conan Doyle, Edgar Rice Burroughs, and more recently, George Macdonald Fraser and Larry McMurtry. Other literary influences include the fictions of C. S. Lewis and John Gardner.Beginning with a fictive treatment of the Lewis & Clark expedition, the narrative frame transitions to a reversal of Burroughs’ Tarzan stories, in which a young African American becomes the Tarzan figure, adventuring in a remote ice age wilderness in post-colonial North America. Within this admittedly outlandish scenario, I’m exploring a dramatic reduction of the war for independence, along with the themes of exploration, subjugation, courage, corruption, and the overlap between racism and speciesism. Though the novel initially presents a ‘‘Disneyesque’’ take on its settings and characters (particularly of Thos. Jefferson), these darken as they progress, leading readers to consider the American stories they are willing or unwilling to accept, against those upon which they insist.
title: Increasing Genetic Testing Rates to Improve Early Detection and Prevention of Breast and Ovarian Cancer in Women
Creators: name: Durrant, Makensey
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Screening rates for cancer related genetic mutations are low in the primary care setting, despite evidence-based guidelines recommending screening in all patients who meet criteria. Genetic mutations, such as the breast cancer susceptibility 1 and 2 (BRCA1/2) gene mutations, drastically increase breast and ovarian cancer risk in patients. The United States Preventive Services Task Force (USPSTF) and the National Comprehensive Cancer Network (NCCN) provide evidence-based guidelines on criteria for genetic testing in women at risk for breast and ovarian cancer related gene mutations. Primary care providers (PCPs), including advanced practice registered nurses (APRNs), are at the front lines of preventative care in the community and should participate in preventative genomic care. Increased adherence to evidence-based guidelines promotes improved patient safety and outcomes. The purpose of this Doctor of Nursing Practice (DNP) project was to increase genetic testing rates to improve early detection and prevention of breast and ovarian cancer in women. This was accomplished through a quality improvement project at a women’s health primary care outpatient clinic. A new practice protocol was introduced that incorporated evidence-based guidelines for both cancer risk assessment and genetic testing. After the Cancer Risk Assessment and Genetic Testing Protocol (CRA/GT- Protocol) was implemented, baseline genetic testing rates were compared to intervention phase genetic testing rates to evaluate usefulness of the protocol. Results demonstrated that the protocol was successful at reducing practice barriers to genetic testing and created a more stable cancer risk assessment system. Further research and interventions are needed to continue to reduce barriers to genetic testing in primary care to promote early detection and prevention of cancer.

description: The aim of this study is to analyze the Earth habitability with respect to the direct exposition of the Earth atmosphere to the solar wind along the Suns evolution on the main sequence including the realistic evolution of the space weather conditions and the Earth magnetic field. The MHD code PLUTO in spherical coordinates is applied to perform parametric studies with respect to the solar wind dynamic pressure and the interplanetary magnetic field intensity for different Earth magnetic field configurations. Quiet space weather conditions may not impact the Earth habitability. On the other hand, the impact of interplanetary coronal mass ejections (ICME) could lead to the erosion of the primary Earth atmosphere during the Hadean eon. A dipolar field of 30 microT is strong enough to shield the Earth from the Eo-Archean age as well as 15 and 5 microT dipolar fields from the Meso-Archean and Meso-Proterozoic, respectively. Multipolar weak field period during the Meso-Proterozoic age may not be a threat for ICME-like space weather conditions if the field intensity is at least 15 microT and the ratio between the quadrupolar (Q) and dipolar (D) coefficients is Q/D <= 0.5. By contrast, the Earth habitability in the Phanerozoic eon (including the present time) can be hampered during multipolar low field periods with a strength of 5 microT and Q/D >= 0.5 associated to geomagnetic reversals. Consequently, the effect of the solar wind should be considered as a possible driver of Earth's habitability.

description: Wireless Sensor Networks need to be organized for efficient data collection and lifetime maximization. In this paper, we propose a novel routing structure, namely k-DAG, to balance the load of the base station's neighbours while providing the worst-case latency guarantee for data collection, and a distributed algorithm for construction a k-DAG based on a SPD (Shortest Path DAG). In a k-DAG, the lengths of the longest path and the shortest path of each sensor node to the base station differ by at most k. By adding sibling edges to a SPD, our distributed algorithm allows critical nodes to have more routing choices. The simulation results show that our approach significantly outperforms the SPD-based data collection approach in both network lifetime and load balance.

title: Selective Serotonin Reuptake Inhibitor (SSRI) Induced Apoptosis of Human Osteoblasts
Creators: name: Doucette, Kimberly
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants. Recent research has shown that SSRIs can effect bone metabolism; however, the exact mechanism is not fully known. The purpose of this study was to determine the effects on human osteoblasts (G -292) following exposure to varying concentrations of the four most commonly prescribed SSRIs including: citalopram (Celexa), fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil). Specifically, we assessed viability, caspase activity (Caspase 3/7, 8 and 9), bcl-2 expression and bax expression. Our results show that cell viability was effected by all drugs, except citalopram, in a concentration dependent manner. Caspase 3/7 activity was increased at 50 μM for sertraline and 80 μM for fluoxetine and paroxetine. Results for caspase 8 and caspase 9 activity were inconclusive. Bcl-2 protein expression appeared to increase at 50 μM in citalopram and fluoxetine and decreased in sertraline and paroxetine; however, experiments were not sufficient to determine statistical significance. Citalopram appears to have less effects on bone metabolism compared to other SSRIs. This preliminary in vitro study suggests citalopram is the antidepressant of choice for treating patients who are also at risk for altered bone homeostasis, including osteoporosis.

description: We study the effect of one-side metallization of a uniform ferromagnetic thin film on its spin-wave dispersion relation in the Damon-Eshbach geometry. Due to the finite conductivity of the metallic cover layer on the ferromagnetic film the spin-wave dispersion relation may be nonreciprocal only in a limited wave-vector range. We provide an approximate analytical solution for the spin-wave frequency, discuss its validity and compare it with numerical results. The dispersion is analyzed systematically by varying the parameters of the ferromagnetic film, the metal cover layer and the value of the external magnetic field. The conclusions drawn from this analysis allow us to define a structure based on a 30 nm thick CoFeB film with an experimentally accessible nonreciprocal dispersion relation in a relatively wide wave-vector range.

title: Revisiting the Smartphone and Learning Inventory (SALI): Perspectives of Preservice Teachers
Creators: name: Daleiden, Bridget
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: The implications of the presence and usage of smartphone technology in learning contexts are not fully understood. Self-regulated learning (SRL) theory offers a theoretical framework in which smartphone use can be explored. Researchers have recently developed a measure of smartphone use while studying, the Smartphone and Learning Inventory (SALI) (Hartley et al., 2020b). The present study is an exploratory qualitative analysis designed to compare open-ended responses to the 3-factor structure of the SALI. A thematic analysis of open-ended responses from a sample of preservice teachers was conducted. The purpose of the current research is to explore themes that may represent experiences related to smartphone use while studying, as well as smartphone-related multitasking behaviors. Key findings are discussed in terms of their implications for the future development of the SALI.

title: Sight Deprivation and Metabolic Effects During the YMCA Bench Press Test
Creators: name: Cruz, Kyle
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Several studies have investigated the effect of sensory deprivation, particularly sight. However, very few have demonstrated the impact of sight deprivation while exercising to cadence blindfolded. This study aimed to determine exercise performance during a common muscular endurance evaluation, the YMCA Bench Press Test (YBPT), while blindfolded compared to a sighted condition. Twenty-five healthy participants (11 male, 14 female, 168 ± 7.7cm, 68 ± 11.7kg, 23 ± 7.5% fat mass) were recruited from the University of Nevada, Las Vegas student populations and communities. After a YBPT familiarization session, participants completed testing in a counterbalanced order, following the same procedures. A paired-samples t-test was used to determine whether there was a statistically significant difference between sighted and blindfolded conditions. There was a difference in the number of repetitions performed wearing a blindfold, 31.48 ± 14.08 compared to not wearing a blindfold, 30.6 ± 14.2, (t(24) = 2.397, p = .025, d= .479). Wearing a blindfold elicited an increase in total kilograms lifted, 753.6 ± 375.4, compared to not wearing a blindfold, 725.7 ± 364.7, t(24) = 2.514, p = .019, d=0.503. Small ES were noted for heart rate during PRE, INTRA, and POST at d=.21, d=.28, and d=.37, respectively. ES was small for PRE VE, d=.21, PRE RER, d=.29, POST VO2, d=.25, and POST VCO2, d=.24. While the blindfold condition did not affect metabolism, performance measures were enhanced. These findings provide evidence that increases in repetitions and overall workload occur while wearing a blindfold during muscular endurance testing (YBPT).Keywords: blindfold, VO2, weight lifting, muscular endurance

description: Background: his paper contains four research contributions made by psychology students within the theoretical framework of Self-Determination Theory. Method: The aim was to investigate the relation between dysfunctional eating behaviors and some related variables, such as basic psychological needs, psychological control, alcohol abuse, body self-esteem, relation anxiety, emotional dysregulation, restrained and emotional eating in 322 adolescents. For each of the variables to be investigated, specific self-report scales were administered. Results: The studies show how satisfaction/frustration of basic psychological needs and emotional dysregulation affect the eating behavior of adolescents. Relationship anxiety, lower satisfaction of basic needs, along with changes in body image, lead to alcohol abuse and emotional eating, especially in females who report higher scores in emotional eating than male adolescents. Conclusions: Further implications of these results for understanding the dysfunctional eating behaviors in adolescents are discussed in the conclusions section of this paper.

description: Virtual YouTubers (VTubers) are avatar-based livestreamers that are voiced and played by human actors. VTubers have been popular in East Asia for years and have more recently seen widespread international growth. Despite their emergent popularity, research has been scarce into the interactions and relationships that exist between avatarized VTubers and their viewers, particularly in contrast to non-avatarized streamers. To address this gap, we performed in-depth interviews with self-reported VTuber viewers (n=21). Our findings first reveal that the avatarized nature of VTubers fosters new forms of theatrical engagement, as factors of the virtual blend with the real to create a mixture of fantasy and realism in possible livestream interactions. Avatarization furthermore results in a unique audience perception regarding the identity of VTubers - an identity which comprises a dynamic, distinct mix of the real human (the voice actor/actress) and the virtual character. Our findings suggest that each of these dual identities both individually and symbiotically affect viewer interactions and relationships with VTubers. Whereas the performer's identity mediates social factors such as intimacy, relatability, and authenticity, the virtual character's identity offers feelings of escapism, novelty in interactions, and a sense of continuity beyond the livestream. We situate our findings within existing livestreaming literature to highlight how avatarization drives unique, character-based interactions as well as reshapes the motivations and relationships that viewers form with livestreamers. Finally, we provide suggestions and recommendations for areas of future exploration to address the challenges involved in present livestreamed avatarized entertainment.

Creators: name: Clontz, Torrie
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Over 605,000 patients will suffer an ST-segment elevated myocardial infarction in the United States each year. The gold-standard definitive treatment for this is percutaneous coronary angioplasty or the ballooning open and stenting of the blockage. The American Heart Association has set the evidence-based gold standard of 90-minutes from identification of blockage to reperfusion of heart muscle. In a health system in Las Vegas, NV, this goal is frequently missed due to lack of protocols in place to expedite patients towards definitive treatment. The purpose of this evidence-based practice change is to reduce STEMI patient morbidity and mortality via a nursing intervention. The PICOT question addressed by this project is: in STEMI patients, does the use of emergency room nurse-managed protocol improve Door-to-Reperfusion time? Evidence for this practice change involves the use of protocols in hospital systems that improved reperfusion times, and the use of protocols during off hours when reperfusion times lag the most. Delays in ambulance transport were also addressed as this provides opportunities to improve EMS to ER communication and throughput. Despite this evidence, there remains a paucity of research regarding the nurse role in reducing Door-to-Reperfusion time. The clinical implications of the evidence show that creating a process or protocol will reduce Door-to-Reperfusion times and thus STEMI patient morbidity and mortality. It is therefore not a reach to infer that a nurse-driven protocol can achieve this goal and that is what this evidence-based practice change seeks to attain.

description: Cognitive radio technology would enable a set of secondary users (SU) to opportunistically use the spectrum licensed to a primary user (PU). On the appearance of this PU on a specific frequency band, any SU occupying this band should free it for PUs. Typically, SUs may collaborate to reduce the impact of cognitive users on the primary network and to improve the performance of the SUs. In this paper, we propose and analyze the performance of virtual reservation in collaborative cognitive networks. Virtual reservation is a novel link maintenance strategy that aims to maximize the throughput of the cognitive network through full spectrum utilization. Our performance evaluation shows significant improvements not only in the SUs blocking and forced termination probabilities but also in the throughput of cognitive users.

description: The aim of this study is to analyze the effect of the neutral beam injector (NBI) operation regime on the saturation phase of the Alfven Eigenmodes (AEs) in DIII-D plasma. The analysis is done using the linear and nonlinear versions of the gyro-fluid code FAR3d. A set of parametric analyses are performed modifying the nonlinear simulation EP \b{eta} (NBI injection power), EP energy (NBI voltage) and the radial location of the EP density profile gradient (NBI radial deposition). The analysis indicates a transition from the soft (local plasma relaxation) to the hard MHD (global plasma relaxation) limit if the simulation EP \b{eta} >= 0.02, leading to bursting MHD activity caused by radial AEs overlapping. MHD bursts cause an enhancement of the EP transport showing ballistic-like features as avalanche-like events. Simulations in the soft MHD limit show an increment of the EP density gradient as the EP \b{eta} increases. On the other hand, there is a gradient upper limit in the hard MHD limit, consistent with the critical-gradient behavior. AEs induce shear flows and zonal current leading to the deformation of the flux surfaces and the safety factor profile, respectively, particularly strong for the simulation in the hard MHD limit. Simulations in the hard MHD regime show a decrease of the AE frequency in the saturation phase; this is caused by the destabilization of a transitional mode between a 9/3-10/3 TAE and a 9/3 RSAE that may explain the AE frequency down-sweeping observed in some DIII-D discharges. Reducing the EP energy in the nonlinear simulations leads to a weakening of the plasma perturbation. On the other hand, increasing the EP energy causes the opposite effect. Nonlinear simulations of off-axis NBI profiles indicate a lower plasma perturbation as the EP density gradient is located further away from the magnetic axis.

description: Background: The influence of parenting strategies and family functioning was extensively analysed in the study of the healthy development of adolescents. Self-determination theory expands this study by suggesting that at the basis of an optimal development there is the satisfaction of basic psychological needs. The aim of this study was to investigate the relation between family functioning and some related variables, such as intrinsic motivation, basic psychological needs, well-being and parental educational practices. Methods: 140 parents with their 70 teenagers took part to this research. For each of the variables to be investigated, specific self-reports were administered. Results: Results found that adolescent self-perceived well-being was related to supportive parental practices and to a better family functioning. Furthermore, basic psychological needs have been found fundamental for the well-being both in parents than in adolescents. Conclusions: The strength of this study lies in having considered family units, investigating the same variables in both parents and children, and finding satisfaction of basic psychological needs to be related to positive well-being outcomes across generations. The practical implications of these findings are discussed.

description: We have measured dissociative recombination of HCl+ with electrons using a merged beams configuration at the heavy-ion storage ring TSR located at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. We present the measured absolute merged beams recombination rate coefficient for collision energies from 0 to 4.5 eV. We have also developed a new method for deriving the cross section from the measurements. Our approach does not suffer from approximations made by previously used methods. The cross section was transformed to a plasma rate coefficient for the electron temperature range from T=10 to 5000 K. We show that the previously used HCl+ DR data underestimate the plasma rate coefficient by a factor of 1.5 at T=10 K and overestimate it by a factor of 3.0 at T=300 K. We also find that the new data may partly explain existing discrepancies between observed abundances of chlorine-bearing molecules and their astrochemical models.

Creators: name: Chenes, Christina
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Richard Danielpour’s (b.1956) song cycle Spirits in the Well (1998) uses four poems penned by Toni Morrison (1931-2019), specifically for Danielpour’s musical setting. Spirits in the Well remains virtually unknown to the general public and artists, as it has never been professionally recorded, despite having been frequently performed by famed soprano Jessye Norman (1945-2019). This document introduces singers to Spirits in the Well by offering a performance guide to the song cycle; it presents information on the text, musical style, structure, form, technical vocal challenges, and dramatic demands that this work places on a singer. Brief background information is provided for both Danielpour and Morrison, as well as a discussion of their contributions and writing styles within their respective fields. In addition, the song cycle’s premiere, performance history, and critical reception are examined.

description: Owing to the variety of possible charge and spin states and to the different ways of coupling to the environment, paramagnetic centres in wide band-gap semiconductors and insulators exhibit a strikingly rich spectrum of properties and functionalities, exploited in commercial light emitters and proposed for applications in quantum information. Here we demonstrate, by combining synchrotron techniques with magnetic, optical and \emph{ab initio} studies, that the codoping of GaN:Mn with Mg allows to control the Mn$^{n+}$ charge and spin state in the range $3\le n\le 5$ and $2\ge S\ge 1$. According to our results, this outstanding degree of tunability arises from the formation of hitherto concealed cation complexes Mn-Mg$_k$, where the number of ligands $k$ is pre-defined by fabrication conditions. The properties of these complexes allow to extend towards the infrared the already remarkable optical capabilities of nitrides, open to solotronics functionalities, and generally represent a fresh perspective for magnetic semiconductors.

title: Towards Highly Sensitive Capacitance Measurements of a Quantum Anomalous Hall Phase in Van Der Waal Heterostructures
Creators: name: Cerminara, Kayla
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: One of the pioneering achievements in condensed matter physics of the 20th century is the observation of the quantum Hall e↵ect (QHE) in which the Hall resistance in a two-dimensional (2D) sample takes on quantized values in the presence of a strong perpendicular magnetic field. The precise quantization of the hall resistance to one part in a billion has provided a practical, worldwide resistance standard. A long-standing goal has been to realize a similar state of matter but without the need of a strong quantizing magnetic field. The quantum anomalous Hall e↵ect (QAHE) is such a state that is predicted to exist in 2D materials with intrinsic magnetism and strong spin orbit coupling. Very few materials have these inherent properties, but new materials can be synthetically engineered by stacking and combining 2D layers into heterostructures with desired characteristics. In this thesis, we work toward combining graphene and few-layer graphene with materials that exhibit strong spin orbit coupling (molybdenum disulfide) with the goal of realizing a robust QAHE. To ascertain the presence of a zero-field gap in the electronic spectrum of the material, a benchmark of the QAHE, we implement a highly sensitive capacitance measurement technique. We present theoretical background on the quantum Hall e↵ects and capacitance measurements to begin. We then present fabrication and measurements of four devices, two incorporating single layer graphene and two with bilayer graphene. Our work opens the door to prospective devices with utility in spintronics and topological quantum computing.

description: We report the experimental observation of anisotropic diffusion of polystyrene particles immersed in a lyotropic liquid crystal with two different anchoring conditions. Diffusion is shown to obey the Stokes-Einstein law for particle diameters ranging from 190 nm up to 2 micron. In the case of prolate micelles, the beads diffuse four times faster along the director than in perpendicular directions. In the theory part we present a perturbative approach to the Leslie-Ericksen equations and relate the diffusion coefficients to the Miesovicz viscosity parameters.We provide explicit formulas for the cases of uniform director field and planar anchoring conditions which are then discussed in view of the data. As a general rule, we find that the inequalities ηb < ηa < ηc, satisfied by various liquid crystals of rodlike molecules, imply Dpar > Dperp.

description: Psychosocial conditions are prevalent in pediatric oncology patients (Kahalley et al., 2013). Family and social support are essential aspects of a patient's health care outcomes (Merck & McElfresh, 2019). Anxiety and depression are common in pediatric oncology patients due to trauma during treatment (Pao & Kazak, 2015). These patients also can have preexisting developmental or behavioral conditions before starting treatment. Treatment side effects can also cause cognitive and behavioral changes (Nixon, 2014b). Nurses should be knowledgeable and confident in their ability to care for patients' psychosocial health and development. The purpose of this Doctor of Nursing Practice (DNP) project is to develop, implement, and evaluate a sustainable program for pediatric oncology nursing staff to increase their knowledge and confidence of family-centered psychosocial care principles with the intent to improve patient care and reduce patient suffering. This project's intervention was to develop a sustainable program to educate pediatric oncology nurses on family-centered psychosocial care. Measurement of the outcome variables, knowledge and confidence, was done before and after the intervention. Descriptive statistics were used for demographic data, displayed as frequencies and percentages. Data from this project's knowledge and confidence assessments were analyzed using a paired t-test and Wilcoxon signed rank test respectively. Qualitative response questions were pooled and assessed for common themes. Statistical analysis revealed that the intervention was effective at improving nurse knowledge and confidence in psychosocial care of pediatric oncology patients. Additional resources were generated after the intervention based on needs identified in the surveys. The results of this project will be disseminated to national publishing groups in hopes of making it available to nurses across the nation.

description: The Braille system has been used by the visually impaired for reading and writing. Due to limited availability of the Braille text books an efficient usage of the books becomes a necessity. This paper proposes a method to convert a scanned Braille document to text which can be read out to many through the computer. The Braille documents are pre processed to enhance the dots and reduce the noise. The Braille cells are segmented and the dots from each cell is extracted and converted in to a number sequence. These are mapped to the appropriate alphabets of the language. The converted text is spoken out through a speech synthesizer. The paper also provides a mechanism to type the Braille characters through the number pad of the keyboard. The typed Braille character is mapped to the alphabet and spoken out. The Braille cell has a standard representation but the mapping differs for each language. In this paper mapping of English, Hindi and Tamil are considered.

title: Political Discussion and Disagreement: Seeking Validation Through News Media
Creators: name: Carmona, Michael
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: This study explores how often individuals discuss politics with family/friends and acquaintances, how often individuals are exposed to disagreement during those discussions, the strategies they use to respond to political disagreement, and the use of news media following those disagreements. Through the lens of Uses and Gratifications theory, this study examined these elements through an online survey of U.S. adults. The results of this study did not support Hopmann’s, Bjarnøe’s, and Wonneberger’s findings about the relationship between the frequency of political disagreement and the strategies for responding to that disagreement. This study highlights how the discussions and disagreements we have about politics can affect why we use the news.

description: We describe a general materials design approach that produces large orbital energy splittings (orbital polarization) in nickelate heterostructures, creating a two-dimensional single-band electronic surface at the Fermi energy. The resulting electronic structure mimics that of the high temperature cuprate superconductors. The two key ingredients are: (i) the construction of atomic-scale distortions about the Ni site via charge transfer and internal electric fields, and (ii) the use of three component (tri-component) superlattices to break inversion symmetry. We use {\it ab initio} calculations to implement the approach, with experimental verification of the critical structural motif that enables the design to succeed.

Dark matter as a ghost free conformal extension of Einstein theory

description: We discuss ghost free models of the recently suggested mimetic dark matter theory. This theory is shown to be a conformal extension of Einstein general relativity. Dark matter originates from gauging out its local Weyl invariance as an extra degree of freedom which describes a potential flow of the pressureless perfect fluid. For a positive energy density of this fluid the theory is free of ghost instabilities, which gives strong preference to stable configurations with a positive scalar curvature and trace of the matter stress tensor. Instabilities caused by caustics of the geodesic flow, inherent in this model, serve as a motivation for an alternative conformal extension of Einstein theory, based on the generalized Proca vector field. A potential part of this field modifies the inflationary stage in cosmology, whereas its rotational part at the post inflationary epoch might simulate rotating flows of dark matter.

Detecting orbital angular momentum through division-of-amplitude interference with a circular plasmonic lens

description: We demonstrate a novel detection scheme for the orbital angular momentum (OAM) of light using circular plasmonic lens. Owing to a division-of-amplitude interference phenomenon between the surface plasmon waves and directly transmitted light, specific intensity distributions are formed near the plasmonic lens surface under different OAM excitations. Due to different phase behaviors of the evanescent surface plasmon wave and the direct transmission, interference patterns rotate as the observation plane moves away from the lens surface. The rotation direction is a direct measure of the sign of OAM, while the amount of rotation is linked to the absolute value of the OAM. This OAM detection scheme is validated experimentally and numerically. Analytical expressions are derived to provide insights and explanations of this detection scheme. This work forms the basis for the realization of a compact and integrated OAM detection architect that may significantly benefit optical information processing with OAM states.

description: We investigated the dispersion of nuclear spin waves in Nd$_2$CuO$_4$ by using neutron spin-echo spectroscopy at millikelvin temperatures. Our results show unambiguously the existence of dispersion of nuclear spin waves in Nd$_2$CuO$_4$ at T = 30 mK. A fit of the dispersion data with the spin wave dispersion formula gave the Suhl-Nakamura interaction range to be of the order of 10 Å.
Chemistry of the Sagittarius Dwarf Galaxy: a Top-Light IMF, Outflows and the R-Process

description: From chemical abundance analysis of stars in the Sagittarius dwarf spheroidal galaxy (Sgr), we conclude that the alpha-element deficiencies cannot be due to the Type Ia supernova (SNIa) time-delay scenario of Tinsley (1979). Instead, the evidence points to low [alpha/Fe] ratios resulting from an initial mass function (IMF) deficient in the highest mass stars. The critical evidence is the 0.4 dex deficiency of [O/Fe], [Mg/Fe] and other hydrostatic elements, contrasting with the normal trend of r-process [Eu/Fe]r with [Fe/H]. Supporting evidence comes from the hydrostatic element (O, Mg, Na, Al, Cu) [X/Fe] ratios, which are inconsistent with iron added to the Milky Way (MW) disk trends. Also, the ratio of hydrostatic to explosive (Si, Ca, Ti) element abundances suggests a relatively top-light IMF. Abundance similarities with the LMC, Fornax and IC 1613, suggest that their alpha-element deficiencies also resulted from IMFs lacking the most massive SNII. For such a top-light IMF, the normal trend of r-process [Eu/Fe]r with [Fe/H], as seen in Sgr, indicates that massive Type II supernovae (>30Msun) cannot be major sources of r-process elements. High [La/Y] ratios, consistent with leaky-box chemical evolution, are confirmed but ~0.3 dex larger than theoretical AGB predictions. This may be due to the 13C pocket mass, or a difference between MW and Sgr AGB stars. Sgr has the lowest [Rb/Zr] ratios known, consistent with low-mass (~2Msun) AGB stars near [Fe/H]=-0.6, likely resulting from leaky-box chemical evolution. The [Cu/O] trend in Sgr and the MW suggest that Cu yields increase with both metallicity and stellar mass, as expected from Cu production by the weak s-process in massive stars. Finally, we present an updated hfs line list, an abundance analysis of Arcturus, and further develop our error analysis formalism.
