Field relations and petrology of the Rainbow Range shield volcano, west-central British Columbia
Creators: name: Bevier, Mary Lou
Publisher: name: University of British Columbia
Year: 2010

description: The Rainbow Range is a Late Miocene shield volcano (30 km diameter, 370 km³) whose stratiform flanks surround a complex central vent zone. Over a time span of 1-2 m.y., extrusion of highly fluid comendites and comenditic trachytes, along with minor mugearites and hawaiites, built up the gently sloping flanks. The viscosity of the peralkaline lavas was so low that their eruption produced a shield volcano rather than a composite cone. Comenditic trachytes (65.5 percent S10₂) are the lowest flows exposed on the north flank of the Rainbow Range. Chemical traits include high Na20 + K/jO (11 percent), moderately high AI₂O₃ (15 percent), low total iron as Fe₂0₃ (5 percent), and high Ba (300-1000 ppm). Thin flows of mugearite (54.9 percent Si0₂) rest on the comenditic trachytes. Comendites (68.7 percent Si02) uncon-formably overlie the mugearites and account for at least 75 percent of the volume of flows within the flank zone. These lavas are distinguished by lower AI2O3 (13 percent), higher total iron as Fe203 (7 percent), and extremely depleted Sr (1-10 ppm) and Ba (10-100 ppm). The termination of flank volcanic activity is recorded by the eruption of capping flows and related feeder dikes of hawaiite (50.1 percent Si0₂). Comenditic trachytes contain phenocrysts of anorthoclase (Or₂₅_₂₇), heden-bergite, and iron-titanium oxides in a groundmass of alkali feldspar, quartz, acmite, iron-titanium oxides, aenigmatite, and arfvedsonite. Comendites bear the phenocryst assemblage sanidine (Or₃₄_₃₇) + hedenbergite + fayalite + arfvedsonite set in a pilotaxitic groundmass of alkali feldspar, quartz, acmite, iron-titanium oxides, aenigmatite, and arfvedsonite. Continuous variation in major and trace element trends and feldspar compositions suggests that the hawaiite-mugearite-comenditic trachyte-comendite suite was derived from an alkali basalt parent, tapped several times as it underwent prolonged fractional crystallization in an intracrustal magma chamber. A best-fit mathematical model for the origin of the suite involves step-wise derivation of the lavas.in the order hawaiite > mugearite ? comenditic trachyte > comendite, with the main phases precipitating out in the order olivine, clinopyroxene, plagioclase, iron-titanium oxide, and alkali feldspar. Strontium isotopic evidence indicates that the peralkaline lavas were erupted soon after differentiation. The Rainbow Range and other peralkaline and alkaline volcanic centers of the Anahim volcanic belt are coeval.with calc-alkaline volcanic centers of the Pemberton volcanic belt. Together these belts outline the orientation and extent of the subducted Juan de Fuca plate during Late Miocene time. Volcanic activity in the Anahim belt may be related to a) an "edge effect" of the subducted Juan de Fuca plate, b) movement of the North American plate over a mantle hot spot at a rate of 2-3 cm/year, or c) an east-west trending rift zone.

description: The circular photogalvanic effect (CPGE) is the only possible quantized signal in Chiral Weyl and multi-fold semimetals with inversion and mirror symmetries broken. Here, we review CPGE in the chiral multifold semimetals in terms of classification of CPGE tensor, the quantization of CPGE from k.p effective model and topological semimetal RhSi family. Firstly, we give complete symmetric analysis of CPGE tensors for all nonmagnetic point groups, and get a table classifying matrix of response tensors. Secondly, the CPGE becomes a quantized response in the noncentrosymmetric topological semimetals, and depends on the Chern number of multifold fermions. Based on k.p effective model with linear dispersion, detailed derivations about the quantization of CPGE are given. Finally, according to ab-initio analysis for the quantized CPGE based on noninteracting electronic structures, we review previous reports and make new calculations for the chiral topological semimetals in RhSi family, which can be separated into two groups. The first group, including RhSi, PtAl and CoSi, can be the promising candidates to exhibit a quantized CPGE trace, while the second group includes PdGa, PtGa and RhSn without a quantization.

description: We propose generalized equilibria of a three-dimensional color-gradient lattice Boltzmann model for two-component two-phase flows using higher-order Hermite polynomials. Although the resulting equilibrium distribution function, which includes a sixth-order term on the velocity, is computationally cumbersome, its equilibrium central moments (CMs) are velocity-independent and have a simplified form. Numerical experiments show that our approach, as in Wen et al. [Phys. Rev. E 100, 023301 (2019)] who consider terms up to third order, improves the Galilean invariance compared to that of the conventional approach. Dynamic problems can be solved with high accuracy at a density ratio of 10; however, the accuracy is still limited to a density ratio of $1\,000$. For lower density ratios, the generalized equilibria benefit from the CM-based multiple-relaxation-time model, especially at very high Reynolds numbers, significantly improving the numerical stability.

description: Early and accurate severity assessment of Coronavirus disease 2019 (COVID-19) based on computed tomography (CT) images offers a great help to the estimation of intensive care unit event and the clinical decision of treatment planning. To augment the labeled data and improve the generalization ability of the classification model, it is necessary to aggregate data from multiple sites. This task faces several challenges including class imbalance between mild and severe infections, domain distribution discrepancy between sites, and presence of heterogeneous features. In this paper, we propose a novel domain adaptation (DA) method with two components to address these problems. The first component is a stochastic class-balanced boosting sampling strategy that overcomes the imbalanced learning problem and improves the classification performance on poorly-predicted classes. The second component is a representation learning that guarantees three properties: 1) domain-transferability by prototype triplet loss, 2) discriminant by conditional maximum mean discrepancy loss, and 3) completeness by multi-view reconstruction loss. Particularly, we propose a domain translator and align the heterogeneous data to the estimated class prototypes (i.e., class centers) in a hyper-sphere manifold. Experiments on cross-site severity assessment of COVID-19 from CT images show that the proposed method can effectively tackle the imbalanced learning problem and outperform recent DA approaches.

description: Background. Several of the intended Plasmodium falciparum vaccine candidate antigens are highly polymorphic and could render a vaccine ineffective if their antigenic sites were not represented in the vaccine. In this study, characterization of genetic variability was performed in major B and T-cell epitopes within vaccine candidate antigens in isolates of P. falciparum from Peru. Methods. DNA sequencing analysis was completed on 139 isolates of P. falciparum collected from endemic areas of the Amazon basin in Loreto, Peru from years 1998 to 2006. Genetic diversity was determined in immunological important regions in circumsporozoite protein (CSP), merozoite surface protein-1 (MSP-1), apical membrane antigen-1 (AMA-1), liver stage antigen-1 (LSA-1) and thrombospondin-related anonymous protein (TRAP). Alleles identified by DNA sequencing were aligned with the vaccine strain 3D7 and DNA polymorphism analysis and FST study-year pairwise comparisons were done using the DnaSP software. Multilocus analysis (MLA) was performed and average of expected heterozygosity was calculated for each loci and haplotype over time. Results. Three different alleles for CSP, seven for MSP-1 Block 2, one for MSP-1 Block 17, three for AMA-1 and for LSA-1 each and one for TRAP were identified. There were 24 different haplotypes in 125 infections with complete locus typing for each gene. Conclusion. Characterization of the genetic diversity in Plasmodium isolates from the Amazon Region of Peru showed that P. falciparum T and B cell epitopes in these antigens have polymorphisms more similar to India than to Africa. These findings are helpful in the formulation of a vaccine considering restricted repertoire populations. © 2008 Chenet et al; licensee BioMed Central Ltd.

description: We have implemented the linear response approximation of a method proposed to compute the electron transport through correlated molecules based on the time-independent Wigner function [P. Delaney and J. C. Greer, \prl {\bf 93}, 36805 (2004)]. The results thus obtained for the zero-bias conductance through quantum dot both without and with correlations demonstrate that this method is either quantitatively nor qualitatively able to provide a correct physical escription of the electric transport through nanosystems. We present an analysis indicating that the failure is due to the manner of imposing the boundary conditions, and that it cannot be simply remedied.

description: The acquisition of new skills and the further development of previous skills has always been one of the ideas behind the graduate recital. Along with new skills come the knowledge and experience necessary to affect the individual's own performance and the performance of those whom he teaches . In music education it is difficult to teach that which one has not yet experienced or mastered and the graduate recital helps to fulfill the experience requirement and give new insights into understanding all aspects of music as a listener, performer, and teacher.
The graduate recital traditionally draws its literature from all periods and representative forms . Because of the limited amount of literature available for the viola in some of these periods, it was necessary to use some transcriptions from the cello works of that period. The program Has selected in consultation with my viola instructor, Professor Ralph Watesky, and did conform to the established standards for graduate recitals.
The recital report is used as an opportunity for the performer to study in some detail the evolution of the musical forms that were represented on his recital. The study of form adds dimension to the music and enhances good performance. Appreciation for the works of each of the composers is developed by studying a representative work in detail for its musical structure. In addition to its historical and musicological significance, the life of the composer i s viewed with its joys and sorrows-- each phase in some way affecting the music that was written.
The development of the musical form, the life of each of the composers, and the analysis of the structural form of each composition are given here as recapitulation of the graduate recital.

description: There is a paradox in the standard model of cosmology. How can matter in the early universe have been in thermal equilibrium, indicating maximum entropy, but the initial state also have been low entropy (the "past hypothesis"), so as to underpin the second law of thermodynamics? The problem has been highly contested, with the only consensus being that gravity plays a role in the story, but with the exact mechanism undecided. In this paper, we construct a well-defined mechanical model to study this paradox. We show how it reproduces the salient features of standard big-bang cosmology with surprising success, and we use it to produce novel results on the statistical mechanics of a gas in an expanding universe. We conclude with a discussion of potential uses of the model, including the explicit computation of the time-dependent coarse-grained entropies needed to investigate the past hypothesis.

description: We aim to obtain a complete sample of redshift > 3.6 radio QSOs from FIRST sources having star-like counterparts in the SDSS DR5 photometric survey (r<=20.2). We found that simple supervised neural networks, trained on sources with SDSS spectra, and using optical photometry and radio data, are very effective for identifying high-z QSOs without spectra. The technique yields a completeness of 96 per cent and an efficiency of 62 per cent. Applying the trained networks to 4415 sources without DR5 spectra we found 58 z>=3.6 QSO candidates. We obtained spectra of 27 of them, and 17 are confirmed as high-z QSOs. Spectra of 13 additional candidates from the literature and from SDSS DR6 revealed 7 more z>=3.6 QSOs, giving and overall efficiency of 60 per cent. None of the non-candidates with spectra from NED or DR6 is a z>=3.6 QSO, consistently with a high completeness. The initial sample of z>=3.6 QSOs is increased from 52 to 76, i.e. by a factor 1.46. From the new identifications and candidates we estimate an incompleteness of SDSS for the spectroscopic classification of FIRST 3.6<=z<=4.6 QSOs of 15 percent for r<=20.2.

Abiotic ammonium formation in the presence of Ni-Fe metals and alloys and its implications for the Hadean nitrogen cycle

description: Experiments with dinitrogen-, nitrite-, nitrate-containing solutions were conducted without headspace in Ti reactors (200°C), borosilicate septum bottles (70°C) and HDPE tubes (22°C) in the presence of Fe and Ni metal, awaruite (Ni80Fe20) and tetrataenite (Ni50Fe50). In general, metals used in this investigation were more reactive than alloys toward all investigated nitrogen species. Nitrite and nitrate were converted to ammonium more rapidly than dinitrogen, and the reduction process had a strong temperature dependence. We concluded from our experimental observations that Hadean submarine hydrothermal systems could have supplied significant quantities of ammonium for reactions that are generally associated with prebiotic synthesis, especially in localized environments. Several natural meteorites (octahedrites) were found to contain up to 22 ppm Ntot. While the oxidation state of N in the octahedrites was not determined, XPS analysis of metals and alloys used in the study shows that N is likely present as nitride (N3-). This observation may have implications toward the Hadean environment, since, terrestrial (e.g., oceanic) ammonium production may have been supplemented by reduced nitrogen delivered by metal-rich meteorites. This notion is based on the fact that nitrogen dissolves into metallic melts. © 2008 Smirnov et al; licensee BioMed Central Ltd.

description: Background: The hepatitis B virus x gene (HBx) is a promiscuous transactivator implicated in the development of hepatocellular carcinoma (HCC). The present study was designed to investigate the molecular events regulated by HBx. Methods: Genomic and proteomic expression profiling was performed in Huh7 HCC cells transfected with HBx mutants with a C-terminal deletion. The gene and protein expression of wingless-type murine-mammary-tumour virus (MMTV) integration site family, member 5A (Wnt-5a) was validated by analyses of reverse transcription-polymerase chain reaction (RT-PCR), real-time RT-PCR, western blot and immunohistochemistry. Results: Differentially expressed genes and proteins were found in the transfected Huh7 HCC cells; most of them were involved in transcriptional regulation, although others including oncogenes or tumor suppressor genes, and molecules involved in cell junctions, signal transduction pathways, metabolism or the immune response were also observed. The expression of the Wnt-5a gene was elevated >10-fold in Huh7 cells transfected with the HBx 3′-30 amino acid deletion mutant. However, the expression was downregulated by the transfection with the HBx 3′-40 amino acid deletion mutant. The changes in Wnt-5a expression were also observed in human HCC tissues, compared with corresponding non-cancerous liver tissues. A negative correlation was found between the expression of Wnt-5a and HBx COOH mutations in HCC tissues. Conclusions: HBx mutants may participate in the development and progression of HCC, at least in part through the Wnt-5a pathway. © The Author 2008. Published by Oxford University Press.

Then, we obtain explicit expressions of these paremeters in terms of the mass of the scalar field (or, differently speaking, the mass of the additional scalar degree of freedom associated to a $f(R)$ theory) which can be used to constrain $f(R)$ gravity by means of current observations.

description: As discussed in this chapter, we develop a mean-field mathematical method to calculate the ground states of antiferromagnets and better understand the applied magnetic-field induced exotic properties. Within antiferromagnetic materials competitive and cooperative interactions exist leading to substance extraordinary magnetic states. Our calculations predict that applying a magnetic field to antiferromagnets can switch it from one magnetic state to another. These include antiferromagnetic ground state, spin-flop transition, spin-flopped state, spin-flip transition and spin-flipped state. Our framework successfully demonstrates these phase changes. With this, a map of all equilibrium magnetic ground states, as well as the respective equilibrium phase conditions, are derived. Our study provides insight into the origins of the various magnetic states.

description: The graduate recital provided an opportunity to reach a new level of performance, a deeper understanding and appreciation of the arts, and a wider knowledge of all aspects affecting one's proficiency as a musician and teacher.
The literature was selected to be representative of the various styles and periods and to feature the special characteristics of the solo instrument, The program for this recital was chosen and approved according to the established tradition of the department of music.
The study and preparation necessary for the performance of these works provided a valuable learning experience that constitutes the most important part of this project, The understanding that any challenge in performance ultimately leads back to a basic mechanical problem has developed an awareness of the importance of fundamentals, Hopefully, the results of this deeper insight will be seen in both teaching and performance.
To more fully understand the musical content of the works performed it was important to review the circumstances and the genius that produced these works, and to consider their place in music literature. and history.

Publisher: name: Utah State University
Year: 1970

description: The song cycle, Frauenliebe und-leben, by Robert Alexander Schumann was selected to be performed in recital and for purposes of this recital report.
Several objectives were to be accomplished in writing this paper. Among these was the intent to achieve a better understanding of the complete poetic and musical lyricism unique to Schumann's songs, particularly those composed in 1840, the period in which the Frauenliebe und-leben wee produced. In addition, an analysis of each of the eight songs in the cycle was undertaken to enable the performer and listener to have better technical understanding of the musical ideas invoked by Schumann and utilized in his songs. A cultural, political, and social overview of the Romantic Period of music during which this composer was working wee incorporated in this report. This portion was included with the purpose of adding understanding of existing attitudes and stylistic characteristics of this time in history.
The objectives generally discussed in the preceding paragraph involved research of an historical nature, supplemented by the individual dissection and analysis of each of the songs within the Frauenliebe und-leben song cycle.
The recital-report offered this student and performer of music a scholarly approach to musical research, allowing a broadening of personal growth and greater respect for the works of Robert Alexander Schumann.
Cache Creek and Nicola Groups near Ashcroft, British Columbia
Creators: name: Grette, Joan Frances
Publisher: name: University of British Columbia

description: Detailed mapping near the type area of the Cache Creek Group in southern British Columbia has led to significant changes in the distribution of Cache Creek and Nicola rocks. Much of what was called Cache Creek Group is now considered to be part of the Upper Triassic Nicola Group. Several criteria can be used to distinguish the two groups. These include: 1) lithologic differences, 2) fossil information, 3) structural style, and 4) metamorphic history. The Cache Creek Group is subdivided into three mappable, fault-bounded units and appears to be a tectonic melange over much of its extent. A deformational event produced isoclinal folds, a phyllitic foliation in some lithologies, and was accompanied by metamorphism with variable pressure-temperature conditions. Mineral assemblages support conditions from temperatures less than 250°C and pressures of 4 kb or less to transitional blueschist conditions: T = 350° C and P = 6 kb. In contrast, the Nicola Group is characterized by hydrothermal alteration and the lack of a pervasive secondary fabric. It does not have the blocks in a sheared matrix tectonostratigraphic style typical of the Cache Creek Group. The two units were brought together along the Martel Fault, probably a thrust, during late Lower or early Middle Jurassic time. Deformation and melange development in the Cache Creek Group predates this event. Distribution of Cache Creek and Nicola rocks and their relationship to each other during Upper Triassic time are still not clear.

The study of demographic characteristics and social relationships are approached by applying machine learning and modern deep-learning Natural Language Processing (NLP) techniques, combining social sciences with automatic text processing. More specifically, our main objective is to combine demographic inference and social analysis in order to detect young Basque Twitter users and to identify the communities that arise from their relationships or shared content. This social and demographic analysis will be entirely based on the~automatically collected tweets using NLP to convert unstructured textual information into interpretable knowledge.

description: Spin-dependent interaction in hadrons is considered in the approach of the QCD string. The string moment of inertia, which ensures the correct (inverse) Regge slope 2*pi*sigma, is found to suppress the spin-orbit interaction. For light quarks and moderate angular momenta the suppression constitutes around 25% whereas for large angular momenta the spin-orbit interaction is suppressed by the factor L^(-2/5). For heavy quarks the effect manifests itself as a string correction for the spin-dependent potential.

A “Humanities-Centered” History of Early AI: Herbert A. Simon and His Books

Year: 2021
Subjects: subject: 200599 Literary Studies not elsewhere classified

description: How should we regard the relationship between literature and artificial intelligence (AI)? Most scholarship in literary studies that examines AI does so by analyzing texts created by machines or by studying AI's representation in pulp science fiction and utopian and dystopian fiction. Some AI researchers have also suggested that books, art, television, and film have shaped the kinds of AIs scientists create. However, what has been less examined is how reading literature has influenced the scientists who invented such technologies. This dissertation fills a gap in literature and science studies by describing how literature played an influential role in the life and work of one of the founders of AI, Herbert A. Simon (b. 1916 – d. 2001). To do so, I created a novel archive of Simon's papers available at Carnegie Mellon University Libraries, totaling about 37,000 documents. I also compared Simon's writing andrelated documents to about 450 books from his library donated to Carnegie Mellon University after his death. My approach to analyzing the Herbert Simon Collection (HSC) adapts a process called "critical search" (Guldi). It combines traditional and digital approaches to self-reflexive search and text-data mining practices in historical archives for guided close reading. In reading for the significance of Simon's source texts, I also draw from citation analysis, theory analysis, and translation studies. Chapter One introduces the ongoing difficulties in tracing the influence of literature on contemporary science fields such as AI and presents the Simon case. Chapter Two describes ahistory of Simon's education as a reader, from his childhood to his training in political science at the University of Chicago. In Chapter Three, I read Simon's first book Administrative Behavior (AB), through the humanist lens of the ancient Greek and Roman tragedies he read, loved, andtranslated. Chapter Four describes how Simon "transmigrated" the individual he proposed in AB into his Logic Theorist program. Finally, in Chapter Four, I also narrate how Simon sought out a theory of free will in conversation with the author Jorge Luis Borges. I find that reading and translating imaginative literary texts activated Simon's receptivity to diverse methodological approaches and contributed to his wide-ranging impact as a researcher.Simon's scientific accomplishments, I argue, were profoundly shaped by his humanities and literary training. Understanding aspects of Simon's work from this perspective offers an alternative, humanities-centered history of early AI, focusing on the significance of literature inscientific and technological innovation.

description: Background: Simple sequence repeats (SSRs) of GACA/GATA have been implicated with differentiation of sex-chromosomes and speciation. However, the organization of these repeats within genomes and transcriptomes, even in the best characterized organisms including human, remains unclear. The main objective of this study was to explore the buffalo transcriptome for its association with GACA/GATA repeats, and study the structural organization and differential expression of the GACA/GATA repeat tagged transcripts. Moreover, the distribution of GACA and GATA repeats in the prokaryotic and eukaryotic genomes was studied to highlight their significance in genome evolution. Results: We explored several genomes and transcriptomes, and observed total absence of these repeats in the prokaryotes, with their gradual accumulation in higher eukaryotes. Further, employing novel microsatellite associated sequence amplification (MASA) approach using varying length oligos based on GACA and GATA repeats; we identified and characterized 44 types of known and novel mRNA transcripts tagged with these repeats from different somatic tissues, gonads and spermatozoa of water buffalo Bubalus bubalis. GACA was found to be associated with higher number of transcripts compared to that with GATA. Exclusive presence of several GACA-tagged transcripts in a tissue or spermatozoa, and absence of the GATA-tagged ones in lung/heart highlights their tissue-specific significance. Of all the GACA/GATA tagged transcripts, ∼30% demonstrated inter-tissue and/or tissue-spermatozoal sequence polymorphisms. Significantly, ∼60% of the GACA-tagged and all the GATA-tagged transcripts showed highest or unique expression in the testis and/or spermatozoa. Moreover, ∼75% GACA-tagged and all the GATA-tagged transcripts were found to be conserved across the species. Conclusion: Present study is a pioneer attempt exploring GACA/GATA tagged transcriptome in any mammalian species highlighting their tissue, stage and species-specific expression profiles. Comparative analysis suggests the gradual accumulation of these repeats in the higher eukaryotes, and establishes the GACA richness of the buffalo transcriptome. This is envisaged to establish the roles of integral simple sequence repeats and tagged transcripts in gene expression or regulation. © 2008 Srivastava et al; licensee BioMed Central Ltd.

description: A systematic analysis of knocking combustion at the knock limit in a single-cylinder research engine is conducted. Both experimental and numerical methods are used to investigate the physical phenomena involved in knocking combustion. While real gasoline fuel can be used directly in experimental studies, this is not feasible in numerical simulations. Here, surrogate fuels with a reduced number of components defined to match the desired properties, such as knock resistance, are employed. In this work, standard gasoline and three surrogate fuels are considered. Differences in composition complexity are covered by selecting isooctane and two toluene reference fuels (TRF) with ethanol addition, all of which exhibit negative temperature coefficient (NTC) behavior in which auto-ignition delay times increase with increasing temperature. Spark timing sweeps at two engine speeds show that the knock resistance of the fuels correlates with the respective research octane number (RON). Isooctane is found to have higher knock resistance and higher sensitivity to engine speed than standard gasoline. One of the two TRFs studied shows good agreement with gasoline in terms of combustion and knock characteristics. The lower knock resistance of the other TRF indicates a non-linear dependence between mixture composition and knock resistance. A strong relative increase in knock resistance at higher engine speeds suggests a possible influence of NTC behavior at lower engine speeds. In the subsequent model-based analysis, the fuel influence on combustion and auto-ignition is investigated, and the laminar burning velocities are found to correlate well with the observed heat durations. While auto-ignition may be triggered by a cool spot at the lower engine speed and at operating conditions within the NTC regime, auto-ignition at the higher engine speed is assumed to be initiated by hot spots. These different mechanisms for initiating auto-ignition were identified as a potential explanation for the different knock resistances observed.
Long-range forces : atmospheric neutrino oscillation at a magnetized detector

description: Among the combinations $L_e-L_μ$, $L_e-L_τ$ and $L_μ-L_τ$ any one can be gauged in anomaly free way with the standard model gauge group. The masses of these gauge bosons can be so light that it can induce long-range forces on the Earth due to the electrons in the Sun. This type of forces can be constrained significantly from neutrino oscillation. As the sign of the potential is opposite for neutrinos and antineutrinos, a magnetized iron calorimeter detector (ICAL) would be able to produce strong constraint on it. We have made conservative studies of these long-range forces with atmospheric neutrinos at ICAL considering only the muons of charge current interactions. We find stringent bounds on the couplings $ α_{eμ, eτ} \lapp 1.65 \times 10^{-53}$ at 3$σ$ CL with an exposure of 1 Mton$\cdot$yr if there is no such force. For nonzero input values of the couplings we find that the potential $V_{eμ}$ opposes and $V_{eτ}$ helps to discriminate the mass hierarchy. However, both potentials help significantly to discriminate the octant of $θ_{23}$. The explanation of the anomaly in recent MINOS data (the difference of $Δm^2_{32}$ for neutrinos and antineutrinos), using long-range force originated from the mixing of the gauge boson $Z^\prime$ of $L_μ-L_τ$ with the standard model gauge boson $Z$, can be tested at ICAL at more than 5$σ$ CL. We have also discussed how to disentangle this from the solution with CPT violation using the seasonal change of the distance between the Earth and the Sun.

description: We calculate the elliptic flow of thermal photons from Au+Au collisions at RHIC energies for a range of values for the formation time $τ_0$ but fixed entropy (or particle rapidity density). The results are found to be quite sensitive to $τ_0$. The $v_2$ for photons decreases as $τ_0$ decreases and admits a larger contribution from the QGP phase which has a smaller $v_2$. The elliptic flow coefficient for hadrons, on the other hand, is only marginally dependent on $τ_0$.

description: Critical Casimir interactions represent a perfect example of bath-induced forces at mesoscales. These forces may have a relevant role in the living systems as well as a role in the design of nanomachines fueled by environmental fluctuations. Since the thermal fluctuations are enhanced in the vicinity of a demixing point of a second-order phase transition, we can modulate the magnitude and range of these Casimir-like forces by slight changes in the temperature. Here, we consider two optical trapped colloidal beads inside a binary mixture. The Casimir interaction is controlled by warming the mixture by laser-induced heating, whose local application ensures high reproducibility. Once this two-particle system is warmed, the critical behavior of different observables allows the system to become its self-thermometer. We use this experimental scheme for analyzing the energetics of a critical colloidal system under a non-equilibrium-driven protocol. We quantify how the injected work can be dissipated to the environment as heat or stored as free energy. Indeed, our system allows us to use the fluctuation theorems framework for analyzing the performance of this critically driven toy model. Our work paves the way for future experimental studies on the non-equilibrium features of bath-induced forces and the design of critically driven nanosystems.
title: Ideal Family Size and Acceptable Contraceptive Devices: A Study of L.D.S. Student Attitudes at Utah State University
Creators: name: Weber, Robert Ray
Publisher: name: Utah State University

description: This study was undertaken because of the seemingly large families of the Mormons in Logan, Utah. Until this year I had never been in an area where Mormons made up a significant proportion of the population and had not realized the apparent difference in family size when compared to non-Mormons.
As a member of the Experienced Teacher Fellowship Program, I also had occasion to take two classes in Marriage and Family in the Family Life College at the University, and this also stirred my interest in the subject.
In the process of reviewing the literature on family size (fertility) and attitudes towards contraception, the conclusion was reached that Mormons do not fit the national norms with reference to these two areas. (They do seem to compare with Catholics and certain fundamentalists groups, however.)
The independent variable that seemed most relevant in an effort to understand the high fertility rate of this particular group was religious commitment. In this study and attempt has been made to find a significant relationship between high religious commitment and the expressed desire for large "ideal family size."
I also hypothesized (mainly by observation) that Mormon S.E.S. was not significant independent variable when considering attitudes towards contraception and family size. After gathering the data and analyzing it, this hypothesis seems incorrect.
Such intervening variables as age, sex, and urban-rural background differences were analyzed in this study to determine to what extent they were and influence.

description: Cancer is frequently considered to be a disease of the cell cycle; alterations in different families of cell cycle regulators cooperate in tumor development. Molecular analysis of human tumors has shown that cell cycle regulators are frequently mutated in human neoplasms, which underscores how important the maintenance of cell cycle commitment is in the prevention of human cancer. The regulatory pathways controlling cell cycle phases include several oncogenes and tumor suppressor genes which display a range of abnormalities with potential usefulness as markers of evolution or treatment response in epithelial ovarian cancer. This review summarizes the current knowledge about these aberrations in malignant tumors of the ovary. We sought to focus our attention on the genes involved in the development of tumors arising from the ovarian epithelium, which are the most common types of ovarian malignancies.
