description: The lower ($H_{c1}$) and upper ($H_{c2}$) critical fields of Mg$_{1-x}$Al$_{x}$B$_2$ single crystals (for $x = 0$, 0.1 and $\gtrsim 0.2$) have been deduced from specific heat and local magnetization measurements, respectively. We show that $H_{c1}$ and $H_{c2}$ are both decreasing with increasing doping content. The corresponding anisotropy parameter $Γ_{H_{c2}}(0) = H^{ab}_{c2}(0)/H^c_{c2}(0)$ value also decreases from $\sim 5$ in pure MgB$_2$ samples down to $\sim 1.5$ for $x \gtrsim 0.2$ whereas $Γ_{H_{c1}}(0)=H^c_{c1}(0)/H^{ab}_{c1}(0)$ remains on the order of 1 in all samples. The small and large gap values have been obtained by fitting the temperature dependence of the zero field electronic contribution to the specific heat to the two gap model for the three Al concentrations. Very similar values have also been obtained by point contact spectroscopy measurements. The evolution of those gaps with Al concentration suggests that both band filling and interband scattering effects are present.

description: Beam stripping losses of H- ion beams by interactions with residual gas and electromagnetic fields are evaluated. These processes play an important role in compact cyclotrons where the beam is produced on an internal ion source, and they operate under high magnetic field. The implementation of stripping interactions into the beam dynamics code OPAL provides an adequate framework to estimate the stripping losses for compact cyclotrons such as AMIT. The analysis is focused on optimizing the high energy beam current delivered to the target. The optimization is performed by adjusting parameters of the ion source to regulate the vacuum level inside the accelerator and minimize the beam stripping losses.

Studies on superovulation and embryo sexing in dairy cattle
Creators: name: Calder, Michele D.
Publisher: name: University of British Columbia

description: The presence of a dominant follicle has been shown to reduce response to superovulatory treatment. Studies were carried out to assess the superovulatory response to FSH/PGF2atreatment using ultrasound scanning and progesterone profiles in the absence of a dominant follicle. The first experiment examined the effect of initiating superovulatory treatment at Day 2 of the estrous cycle, before a dominant follicle was identifiable. Although adequate follicular development occurred after administration of superovulatory hormones, few animals demonstrated estrus and ovulation rates and the number of embryos recovered was low. In the second experiment, humanchorionic gonadotrophin (hCG) was used to remove the dominant follicle present at Day 7 of the estrous cycle prior to induction of superovulation on Day 9. Cows treated with hCG tended to have higher numbers of follicles, corpora lutea and embryos recovered after treatment, however values were not significantly different from control cows superovulated at mid-cycle. Because the cost of superovulation and embryo transfer is high, economically it may be necessary to produce only calves of the desired sex. Several methods have been used to select for calves of the desired sex, including: production of sexed semen; determination of fetal sex in early pregnancy; and detection and selection of the sex of preimplantation bovine embryos prior to embryo transfer. Two methods of selection of embryonic sex were investigated. Karyotyping was done to directly visualize the sex chromosomes of bovine preimplantation embryos. Previously, anti-H-Y antisera has been used in vitro and in vivo to select against male cells. Antibodies to H-Yantigen were produced in female mice after several weeks of immunization against male cells. Anti-H-Y antibody titre was assessed in enzyme-linked immunosorbent assays (ELISAs).Immunized females were then bred to study the effect of H-Y antibodies on litter size and sex ratio. Unexpectedly, increases in the male offspring were noted in the first litters of immunized females.
Relativistic Chiral Hartree-Fock description of nuclear matter with constraints from nucleon structure and confinement

description: We present a relativistic chiral effective theory for symmetric and asymmetric nuclear matter taken in the Hartree-Fock scheme. The nuclear binding is insured by a background chiral invariant scalar field associated with the radial fluctuations of the chiral quark condensate. Nuclear matter saturation is obtained once the scalar response of the nucleon generating three-body repulsive forces is incorporated. For these parameters related to the scalar sector and quark confinement mechanism inside the nucleon we make use of an analysis of lattice results on the nucleon mass evolution with the quark mass. The other parameters are constrained as most as possible by standard hadron and nuclear phenomenology. Special attention is paid to the treatment of the propagation of the scalar fluctuations. The rearrangement terms associated with in-medium modified mass and coupling constants are explicitly included to satisfy the Hugenholtz -Van Hove theorem. We point out the important role of the tensor piece of the rho exchange Fock term to reproduce the asymmetry energy of nuclear matter. We also discuss the isospin dependence of the Landau nucleon effective mass.

Women’s work and family roles in a bicultural context : the case of Indochinese refugees
Creators: name: Wing, Jennifer Lynn
Publisher: name: University of British Columbia
Year: 2008

description: This study examines women's work and family roles in a bicultural context. The Deacon and Firebaugh family resource management framework was used to develop a model to investigate (a) how women integrate two cultures' values towards work and family roles; (b) how orientations towards these roles affect perceptions of interrole compatibility; (c) how orientations towards these roles affect satisfaction with health, standard of living, job, and psychological well-being; and (d) how interrole compatibility perceptions affect satisfaction with health, standard of living, job, and psychological well-being. Data were from the third wave of an ongoing 10-year longitudinal study on refugee resettlement. All seventy-five women that comprised the sample held work and family roles. Measures were constructed to assess orientations towards work and family roles, perceptions of interrole compatibility, and involvement in each of the roles. Results found support for a typology of work and family role orientations which placed women into the categories of Assimilated, Integrated Type I, Integrated Type II, and Separated. The Assimilated and Integrated Type I group scored higher on interrole compatibility perceptions; the Assimilated group was found to have higher levels of satisfaction with their health and greater well-being than the other three groups. No support was found for the effects of interrole compatibility on satisfaction with health, standard of living, job, and well being. Results of these findings are discussed in terms of the model developed for the study, and in terms of the issues raised about acculturation and immigrant womens' experience with work and family roles.

description: Echo chambers in online social networks, whereby users' beliefs are reinforced by interactions with like-minded peers and insulation from others' points of view, have been decried as a cause of political polarization. Here, we investigate their role in the debate around the 2016 US elections on Reddit, a fundamental platform for the success of Donald Trump. We identify Trump vs Clinton supporters and reconstruct their political interaction network. We observe a preference for cross-cutting political interactions between the two communities rather than within-group interactions, thus contradicting the echo chamber narrative. Furthermore, these interactions are asymmetrical: Clinton supporters are particularly eager to answer comments by Trump supporters. Beside asymmetric heterophily, users show assortative behavior for activity, and disassortative, asymmetric behavior for popularity. Our findings are tested against a null model of random interactions, by using two different approaches: a network rewiring which preserves the activity of nodes, and a logit regression which takes into account possible confounding factors. Finally, we explore possible socio-demographic implications. Users show a tendency for geographical homophily and a small positive correlation between cross-interactions and voter abstention. Our findings shed light on public opinion formation on social media, calling for a better understanding of the social dynamics at play in this context.

description: Η παρούσα εργασία εξετάζει τόσο την ανατομική όσο και την χειρουργική αξία του συνδέσμου του Berry. Ως προς το πρώτο κομμάτι γίνεται εκτεταμένη αναφορά στη βιβλιογραφία και εξάγονται τα ανάλογα συμπεράσματα. Ως προς το δεύτερο σκέλος γίνεται μια συστηματική ανασκόπηση της βιβλιογραφίας με όλα τα κριτήρια των σύγχρονων κατευθυντήριων οδηγιών. Ο σύνδεσμος του Berry αποτελεί το πιο αξιόπιστο ανατομικό στοιχείο για την αναγνώριση του παλινδρόμου λαρυγγικού νεύρου σε σύγκριση με άλλες ανατομικές δομές καθώς έχει την πιο σταθερή σχέση με αυτό. Η χειρουργική αξία του συνδέσμου οφείλεται στο αυξημένο ποσοστό κακώσεων του νεύρου σε αυτή την ανατομική περιοχή κατά την χειρουργική θυρεοειδή - παραθυρεοειδών. Εξετάζεται η σχέση αυτή μέσα στο σύγχρονο πλαίσιο της νευροδιέγερσης με την ευρεία εφαρμογή που έχει σήμερα στην χειρουρική κεφαλής και τραχήλου. Ακολουθεί όλες τις προδιαγραφές τόσο του συστήματος PRISMA όσο και τις κατευθυντήριες οδηγίες των Henry et al (2016) πάνω στις ανατομικές συστηματικές ανασκοπήσεις.
description: The present study examines both the anatomical and surgical importance of Berry's ligament. At the first part there is an extensive review to the literature and the corresponding conclusions are drawn. Regarding to the second part there is a systematic review of the literature with all the criteria of the modern guidelines. The ligament of Berry is the most reliable anatomical landmark for the identification of the recurrent laryngeal nerve compared to other anatomical structures since it has the most stable relationship to it. The surgical importance of the ligament is due to the increased rate of nerve injuries in this anatomical area during thyroid - parathyroid surgery (66%). The study examines the relationship of Berry’s ligament and recurrent laryngeal nerve injury within the innovative concept of neuromonitoring in the head and neck surgery. It follows the guidelines of both PRISMA and the Henry et al (2016) systems on anatomical reviews and meta-analyses.

description: In the context of the ClearMind project, we measured the scintillating properties, as induced from from gamma ray interactions, of today available PbWO4 crystal. We measured scintillation s yields and time constants by measuring the signal shape measured on a fast photo-multiplier and deconvoluting it from the instrumental effects. For the doped crystals at room temperature, we measured a fast scintillation component, with time constants of 2 ns, 55 percent of the total light yield, and a slow component of 6 ns. We observe a significant increase of the light yield for the slow component when the temperature decreases and simultaneous increase of the time constants, but no increase in the fast component light yield. Our measurements reproduce the main qualitative features of PbWO4 crystals quoted in the literature. Quantitatively though, we measured significantly shorter time constants and larger light yields. This is explained by a rigorous treatment of the instrumental contributions in the measurements. Results are discussed and prospect for future developments, tailored for the ClearMind project, are presented.

description: The nonlinear mean-field dynamo due to a shear-current effect in a nonhelical homogeneous turbulence with a mean velocity shear is discussed. The transport of magnetic helicity as a dynamical nonlinearity is taken into account. The shear-current effect is associated with the ${\bf W} {\bf \times} {\bf J}$ term in the mean electromotive force, where ${\bf W}$ is the mean vorticity due to the large-scale shear motions and ${\bf J}$ is the mean electric current. This effect causes the generation of large-scale magnetic field in a turbulence with large hydrodynamic and magnetic Reynolds numbers. The dynamo action due to the shear-current effect depends on the spatial scaling of the correlation time $τ(k)$ of the background turbulence, where $k$ is the wave number. For Kolmogorov scaling, $τ(k) \propto k^{-2/3}$, the dynamo instability occurs, while when $τ(k) \propto k^{-2}$ (small hydrodynamic and magnetic Reynolds numbers) there is no the dynamo action in a sheared nonhelical turbulence. The magnetic helicity flux strongly affects the magnetic field dynamics in the nonlinear stage of the dynamo action. Numerical solutions of the nonlinear mean-field dynamo equations which take into account the shear-current effect, show that if the magnetic helicity flux is not small, the saturated level of the mean magnetic field is of the order of the equipartition field determined by the turbulent kinetic energy. Turbulence with a large-scale velocity shear is a universal feature in astrophysics, and the obtained results can be important for elucidation of origin of the large-scale magnetic fields in astrophysical sheared turbulence.

The model includes the transverse component of the initial parton distribution. We compare our results for pp collision to experimental data at RHIC energy. We repeat our calculation for the dAu collision and investigate the interplay between shadowing and multiple scattering. In central $]dAu collisions the influence of possible jet energy loss on cold nuclear matter is discussed and numerical results are displayed.

description: The electronic properties of bilayer graphene with a magnetic quantum dot and a magnetic quantum ring are investigated. The eigenenergies and wavefunctions of quasiparticle states are calculated analytically by solving decoupled fourth-order differential equations. For the magnetic quantum dot, in the case of a negative inner magnetic field, two peculiar characteristics of the eigenenergy evolution are found: (i) the energy eigenstates change in a stepwise manner owing to energy anticrossing and (ii) the quantum states approach zero energy. For the magnetic quantum ring, there is an angular momentum transition of eigenenergy as the inner radius of the ring varies, and the Aharonov--Bohm effect is observed in the eigenenergy spectra for both positive and negative magnetic fields inside the inner radius.

The origin of the ($B-L$)-conserving high singlet neutrino scale and the desired supersymmetry breaking terms is associated with dynamical supersymmetry breaking in the hidden sector.

description: Understanding collisions between ultracold molecules is crucial for making stable molecular quantum gases and harnessing their rich internal degrees of freedom for quantum engineering. Transient complexes can strongly influence collisional physics, but in the ultracold regime, key aspects of their behavior have remained unknown. To explain experimentally observed loss of ground-state molecules from optical dipole traps, it was recently proposed that molecular complexes can be lost due to photo-excitation. By trapping molecules in a repulsive box potential using laser light near a narrow molecular transition, we are able to test this hypothesis with light intensities three orders of magnitude lower than what is typical in red-detuned dipole traps. This allows us to investigate light-induced collisional loss in a gas of nonreactive fermionic $^{23}$Na$^{40}$K molecules. Even for the lowest intensities available in our experiment, our results are consistent with universal loss, meaning unit loss probability inside the short-range interaction potential. Our findings disagree by at least two orders of magnitude with latest theoretical predictions, showing that crucial aspects of molecular collisions are not yet understood, and provide a benchmark for the development of new theories.

description: Hawking's stable causality implies Sorkin and Woolgar's K-causality. The work investigates the possible equivalence between the two causality requirements, an issue which was first considered by H. Seifert and then raised again by R. Low after the introduction of K-causality. First, a new proof is given that a spacetime is stably causal iff the Seifert causal relation is a partial order. It is then shown that given a K-causal spacetime and chosen an event, the light cones can be widened in a neighborhood of the event without spoiling K-causality. The idea is that this widening of the light cones can be continued leading to a global one. Unfortunately, due to some difficulties in the inductive process the author was not able to complete the program for a proof as originally conceived by H. Seifert. Nevertheless, it is proved that if K-causality coincides with stable causality then in any K-causal spacetime the K future coincides with the Seifert future. Explicit examples are provided which show that the K^+ future may differ from the Seifert relation in causal spacetimes.

Research in databases PubMed, Medline and Scopus was performed in order to find available literature. Seven articles, published since the oldest available date until today, were chosen for further investigation. According to our findings, none of studies presented consistent outcomes; however, each separately suggested better rehabilitation of the patients, improved knee flexion and knee extension and fastest improvement of their walking ability. Further research is required in order to establish new combined protocols that aim to make the athletes rehabilitation faster and provide them a better quality of life.

description: We have investigated the dielectric anomalies associated with spin ordering transitions in the tetragonal spinel Mn$_3$O$_4$, using thermodynamic, magnetic, and dielectric measurements. We find that two of the three magnetic ordering transitions in Mn$_3$O$_4$ lead to decreases in the temperature dependent dielectric constant at zero applied field. Applying a magnetic field to the polycrystalline sample leaves these two dielectric anomalies practically unchanged, but leads to an increase in the dielectric constant at the intermediate spin-ordering transition. We discuss possible origins for this magnetodielectric behavior in terms of spin-phonon coupling. Band structure calculations suggest that in its ferrimagnetic state, Mn$_3$O$_4$ corresponds to a semiconductor with no orbital degeneracy due to strong Jahn-Teller distortion.

description: In preparation for a demonstration of optical stochastic cooling in the Cornell Electron Storage Ring (CESR) we have developed a particle tracking simulation to study the relevant beam dynamics. Optical radiation emitted in the pickup undulator gives a momentum kick to that same particle in the kicker undulator. The optics of the electron bypass from pickup to kicker couples betatron amplitude and momentum offset to path length so that the momentum kick reduces emittance and momentum spread. Nearby electrons contribute an incoherent noise. Layout of the bypass line is presented that accommodates optics with a range of transverse and longitudinal cooling parameters. The simulation is used to determine cooling rates and their dependence on bunch and lattice parameters for bypass optics with distinct emittance and momentum acceptance.

description: We describe AEGIS20 - a radio survey of the Extended Groth Strip (EGS) conducted with the Very Large Array (VLA) at 1.4GHz. The resulting catalog contains 1,123 emitters and is sensitive to ultraluminous starbursts to z<=1.3, well matched to the redshift range of the DEEP2 spectroscopic survey in this region. We use stacking techniques to explore the uJy-level emission from a variety of galaxy populations selected via conventional criteria - Lyman-break galaxies (LBGs), distant red galaxies (DRGs), UV-selected galaxies and extremely red objects (EROs) - determining their properties as a function of color, magnitude and redshift and their extinction-free contributions to the history of star formation. We confirm the familiar pattern that the star-formation-rate (SFR) density, SFRD, rises by at least ~5x from z=0-1, although we note highly discrepant UV- and radio-based SFR estimates. Our radio-based SFRs become more difficult to interpret at z>1 where correcting for contamination by radio-loud active galactic nuclei (AGN) comes at the price of rejecting luminous starbursts. Whilst stacking radio images is a useful technique, accurate radio-based SFRs for z>>1 galaxies require precise redshifts and extraordinarily high-fidelity radio data to identify and remove accretion-related emission.

We are a cell aren’t we? : art and language and the documenta index
Creators: name: Wood, William
Publisher: name: University of British Columbia

description: In 1972, "Documenta 5" was held in Kassel, West Germany, an exhibition of 160 artists under the theme "Questioning Reality: Today's Imagery." A section of this thematic exhibition presented conceptual art, including an installation called a Survey of the Art & Language Institute (1968-1972). This work comprised: eight filing cabinets containing writing by or published by the Art & Language group; photostats pinned to the walls listing relations of compatibility between each of the texts; posters with texts concerning the work and a lattice displaying the compatibility-relations between most of the texts. The texts in the files and on the poster discussed art practice using an obtuse language culled from analytic philosophy and information theory-the idiom associated with Art & Language. This is the first of several works by Art & Language which have come to be called indexes, this one now known as the Documenta Index. The group was formed as the Art & Language Press in 1968 by four art teachers and students in Coventry, England: Terry Atkinson, David Bainbridge, Michael Baldwin and Harold Hurrell. After 1969, they published Art-Language, a journal analyzing "the language-use of the art society," and quickly positioned themselves in the vanguard of conceptualism. Through recruiting new members and by extended associations with international artists, dealers, critics and curators, Art & Language became notables in the "art society" they critiqued, extenting their influence, expanding their numbers to 10, and re-naming themselves, for "Documenta 5", the Art & Language Institute. The Documenta Index represents a major shift in their programme, mixing the idea of textbased art theory with an attempt to out-maneuver an international exhibition by calling for extended audience participation. The Index also marked out external and internal problems with organizing and presenting group work-and attempted to negotiate an analytical standing for the association in the art market and social world of the early-seventies. It is the formation of the group, the formulation of its programme and its address to—and assumptions about-spectators which forms the major material for the study, with particular attention to the English art-college origins of the group and the aesthetic and social politics of the trans-Atlantic environment they came to operate within. By looking at the way in which the group constituted itself and was regarded by others, a picture emerges of how the Documenta Index came to exist, and why the type of openness in argument it presented—the dedication to pursue questions rather than resolve them in plastic form—both challenged and went unengaged in the atmosphere of the early-seventies. In conclusion, the contradictory aspects of the Index and the exhibition it was produced for are understood as representing both the possibilities of openness and the difficulties of presenting critical thought and a critical identity in the form of art.

description: We consider here scalar and electromagnetic perturbations for the Vaidya metric in double-null coordinates. Such an approach allows one to go a step further in the analysis of quasinormal modes for time-dependent spacetimes. Some recent results are refined, and a new non-stationary behavior corresponding to some sort of inertia for quasinormal modes is identified. Our conclusions can enlighten some aspects of the wave scattering by black holes undergoing some mass accretion processes.

description: The Event Horizon Telescope (EHT) is a very long baseline interferometer built to image supermassive black holes on event-horizon scales. In this paper, we investigate candidate sites for an expanded EHT array with improved imaging capabilities. We use historical meteorology and radiative transfer analysis to evaluate site performance. Most of the existing sites in the EHT array have median zenith opacity less than 0.2 at 230 GHz during the March/April observing season. Seven of the existing EHT sites have 345 GHz opacity less than 0.5 during observing months. Out of more than forty candidate new locations analyzed, approximately half have 230 GHz opacity comparable to the existing EHT sites, and at least seventeen of the candidate sites would be comparably good for 345 GHz observing. A group of new sites with favorable transmittance and geographic placement leads to greatly enhanced imaging and science on horizon scales.

description: Intercultural competence is essential in today’s globalized world, yet research on its development in short-term study abroad programs remains limited, particularly in Japan. While previous studies suggest that even short-term programs can foster intercultural competence, further validation is needed. Study abroad is widely regarded as a means to enhance intercultural competence, but research indicates that immersion alone is insufficient; structured interventions are essential for meaningful learning. This study aims to examine (1) how participation in a 10-day study abroad program in Japan affects students' intercultural competence and (2) what types of faculty interventions can enhance participants' intercultural development during such a program. The study involved 15 students from Purdue University who participated in a faculty-led program in Japan. Data were collected through pre- and post-program quantitative assessments using the Intercultural Development Inventory (IDI) and the Cultural Intelligence Scale (CQS), alongside qualitative data from participants’ daily reflections and a post-program survey.Quantitative results indicated statistically significant growth in intercultural competence as measured by the IDI; however, no similar growth was observed in the CQS. Qualitative analysis of daily reflections and post-program surveys revealed that intentional faculty interventions played a crucial role in enhancing students' intercultural development. Key activities included guided visits to cultural sites, interaction with Japanese college students, a one-day home visit, and daily reflections.The study reinforces previous research, demonstrating that well-structured short-term programs can foster intercultural competence. Furthermore, it underscores the essential role of faculty involvement and intentional interventions in maximizing the effectiveness of short-term study abroad experiences, ultimately supporting the growth of students' intercultural competence.

description: Context: We present 31.2 days of nearly continuous MOST photometry of the roAp star 10Aql. Aims:The goal was to provide an unambiguous frequency identification for this little studied star, as well as to discuss the detected frequencies in the context of magnetic models and analyze the influence of the magnetic field on the pulsation. Methods: Using traditional Fourier analysis techniques on three independent data reductions, intrinsic frequencies for the star are identified. Theoretical non-adiabatic axisymmetric modes influenced by a magnetic field having polar field strengths Bp = 0-5kG were computed to compare the observations to theory. Results: The high-precision data allow us to identify three definite intrinsic pulsation frequencies and two other candidate frequencies with low S/N. Considering the observed spacings, only one (50.95microHz) is consistent with the main sequence nature of roAp stars. The comparison with theoretical models yields a best fit for a 1.95Msun model having solar metallicity, suppressed envelope convection, and homogenous helium abundance. Furthermore, our analysis confirms the suspected slow rotation of the star and sets new lower limits to the rotation period (Prot>1 month) and inclination (i>30\pm10deg.). Conclusions:The observed frequency spectrum is not rich enough to unambiguously identify a model. On the other hand, the models hardly represent roAp stars in detail due to the approximations needed to describe the interactions of the magnetic field with stellar structure and pulsation. Consequently, errors in the model frequencies needed for the fitting procedure can only be estimated. Nevertheless, it is encouraging that models which suppress convection and include solar metallicity, in agreement with current concepts of roAp stars, fit the observations best.

description: The accurate identification and control of plasma instabilities is important for successful fusion experiments. First-principles simulations which can provide physics based instability information including the growth rate and mode structure are generally not fast enough for real-time applications. In this work, a deep-learning based surrogate model as an instability simulator has been developed and trained in a supervised manner with data from the gyrokinetic toroidal code (GTC) global electromagnetic simulations of the current driven kink instabilities in DIII-D plasmas. The inference time of the surrogate model of GTC (SGTC) is on the order of milliseconds, which fits the requirement of the DIII-D real-time plasma control system (PCS). SGTC demonstrates strong predictive capabilities for the kink mode instability properties including the growth rate and mode structure.
