description: We study the mixing of the Gluino-Glue operator in ${\cal N}$=1 Supersymmetric Yang-Mills theory (SYM), both in dimensional regularization and on the lattice. We calculate its renormalization, which is not only multiplicative, due to the fact that this operator can mix with non-gauge invariant operators of equal or, on the lattice, lower dimension. These operators carry the same quantum numbers under Lorentz transformations and global gauge transformations, and they have the same ghost number. We compute the one-loop quantum correction for the relevant two-point and three-point Green's functions of the Gluino-Glue operator. This allows us to determine renormalization factors of the operator in the $\overline{\textrm{MS}}$ scheme, as well as the mixing coefficients for the other operators. To this end our computations are performed using dimensional and lattice regularizations. We employ a standard discretization where gluinos are defined on lattice sites and gluons reside on the links of the lattice; the discretization is based on Wilson's formulation of non-supersymmetric gauge theories with clover improvement. The number of colors, $N_c$, the gauge parameter, $β$, and the clover coefficient, $c_{\rm SW}$, are left as free parameters.

description: Οι ψυχολογικές τεχνικές όπως ο καθορισμός στόχων, η νοερή απεικόνιση, η αυτο-ομιλία και οι προαγωνιστικές ρουτίνες μπορούν να βελτιώσουν την απόδοση των αθλητών και αθλητριών. Στην καλαθοσφαίριση οι προαγωνιστικές ρουτίνες αποτελούν μια από τις πιο ευρέως χρησιμοποιούμενες τεχνικές. Σκοπός της παρούσας έρευνας ήταν να εξετάσει τη σχέση των προαγωνιστικών ρουτινών και ευστοχίας κατά την εκτέλεση ελευθέρων βολών σε αγώνες πρωταθλήματος Α1 γυναικών στην καλαθοσφαίριση. Συνολικά στην έρευνα συμμετείχαν 87 αθλήτριες σε σύνολο 24 αγώνων καλαθοσφαίρισης Α1 κατηγορίας γυναικών (πρωταθλήματος και κυπέλου). Για την καταγραφή των δεδομένων χρησιμοποιήθηκε βιντεοανάλυση και για τη στατιστική ανάλυση η μη παραμετρική μέθοδος του χ2 test (chi-square) με το επίπεδο σημαντικότητας να ορίζεται στο p < .05. Σε γενικές γραμμές, τα αποτελέσματα δεν έδειξαν στατιστικά σημαντική σχέση μεταξύ προαγωνιστικών ρουτινών και ευστοχίας κατά την εκτέλεση ελευθέρων βολών. Ωστόσο στατιστικά σημαντική σχέση παρουσιάστηκε στη δεύτερη βολή του δεύτερου ζεύγους βολών. Τα αποτελέσματα συζητούνται με βάση τη βιβλιογραφία στις προαγωνιστικές ρουτίνες και δίνονται πρακτικές συμβουλές και προτάσεις για μελλοντικές έρευνες.
description: Psychological techniques such as goal-setting, imagery, self-talk and pre-performance routines can enhance athletes’ performance. In basket-ball one of the most used techniques is the pre-performance routines. Thus, the purpose of this study was to examine the relationship between pre-performance routines and accuracy in performing free-throw in A1 league women in basketball. Eighty seven female athletes participated in the study, from 24 basketball games of A1 league (league and cup). Video analysis was used for the identification of the pre-performance routines and the non parametric χ2 (chi-square) test for the analysis of the data. In general, the results did not show significant relationship between pre-performance routine and accuracy in performing free-throw (3 free-throws). But statistically significant relationship was presented in the last free-throw. The results are discussed based on pre-performance routines’ literature and practical advice and suggestions are given for future research.

Comparison of cell line dilutions and the number of fusion-supporting reads divided by the total read depth for the SureSelect XT HS Custom Panel (Agilent) v4.0.1.46 (A) and v4.1.1.5 (B). Depicted are the gene fusion-supporting reads divided by the total read depth of the 10%, 20%, 50%, 80% and 90% tumor cell dilutions of the eight cell lines. For each cell line, except the RT4 cells, a regression line and the coefficient of determination (R2) is shown. In the RT4 cells in v4.0.1.46 the fusion was only called in the 80% and 90% dilution and in v4.1.1.5 the fusion was only called in one direction by the TACC3 gene and not the FGFR3 gene in the 50%, 80% and 90% dilution. Thus, the values are not corresponding to the other values as they are much higher.

description: One of humanity's earliest mathematical inquiries might have involved the geometric patterns in plants. The arrangement of leaves on a branch, seeds in a sunflower, and spines on a cactus exhibit repeated spirals, which appear with an intriguing regularity providing a simple demonstration of mathematically complex patterns. Surprisingly, the numbers of these spirals are pairs of Fibonacci numbers consecutive in the series 1, 2, 3, 5, 8, 13, 21, 34, 55... obeying a simple rule 1+2=3, 2+3=5, 5+8=13 and so on. This article describes how physics helps to clarify the origin of this fascinating behavior by linking it to the properties of deformable lattices growing and undergoing structural rearrangements under stress.
The similarities and differences of men’s and women’s personal work networks

description: Although network analysis has proven a useful approach to the study of organizations and organizational behavior, very little research has been done on the issue of gender differences in personal work networks. While there is considerable conventional wisdom about how men and women associate with their colleagues in the workplace, the matter still requires scientific scrutiny. The purpose of this thesis is to provide much needed descriptive evidence about the ways and extent to which the personal work networks of men and women managers or supervisors differ, and to illustrate how promotions impact such networks. Two separate studies comprise the thesis. The first study considered the personal work networks of men and women supervisors or managers who had not undergone formal career transitions in the previous 12 months. Network characteristic data were generated through a questionnaire returned by 242 individuals, representing three large Canadian companies in the banking, forestry, and insurance industries. Multiple regression was used to test for gender differences and company moderator effects. Contrary to the common assumption currently found in the literature that there are gender differences in personal work networks, this study found that differences in men’s and women’s association patterns at work were more likely in their expressive, rather than instrumental, networks. Though managers and supervisors were more likely to form homophilous ties, and men had networks of greater density, the results suggested that men and women had comparable instrumental work networks. The expressive networks, however, exhibited greater gender differences. Significant differences included the gender, location, the density, and the frequency of contact of these expressive ties. The second study considered the personal work networks of men and women supervisors or managers who had recently been promoted. Network characteristic data were generated through a questionnaire returned by 33 individuals working for a leading Canadian bank; however, possibly because of sampling deficiencies, no significant instrumental or expressive network differences were identified. Moreover, there were no differences in the turnover of individuals in men’s and women’s instrumental and expressive networks following promotions. A discussion regarding the status and future of personal work network research concludes the thesis.
A Goldilocks Higgs

description: If the Higgs is not a CP eigenstate, it can couple to a topological 4-form sector which yields a complex vacuum structure. In many of the Higgs vacua electroweak symmetry is unbroken. In just as many it breaks when the 4-form flux is large enough. For a fixed value of flux, the symmetry breaking vacua have a smaller vacuum energy than the symmetric ones, where the difference is quantized because it is set by the 4-form flux. This leads to the possibility that there is a value of the 4-form flux for any UV contributions to the Higgs vev that automatically cancels it down to the right value, $\sim$ TeV, if the 4-form charges are quantized in the units of the electroweak scale. This would still leave the cosmological constant which could be selected anthropically.

description: Interferometric observations of two well-known Be stars, gamma Cas and phi Per, were collected and analyzed to determine the spatial characteristics of their circumstellar regions. The observations were obtained using the Navy Prototype Optical Interferometer equipped with custom-made narrowband filters. The filters isolate the H-alpha emission line from the nearby continuum radiation, which results in an increased contrast between the interferometric signature due to the H-alpha-emitting circumstellar region and the central star. Because the narrowband filters do not significantly attenuate the continuum radiation at wavelengths 50 nm or more away from the line, the interferometric signal in the H-alpha channel is calibrated with respect to the continuum channels. The observations used in this study represent the highest spatial resolution measurements of the H-alpha-emitting regions of Be stars obtained to date. These observations allow us to demonstrate for the first time that the intensity distribution in the circumstellar region of a Be star cannot be represented by uniform disk or ring-like structures, whereas a Gaussian intensity distribution appears to be fully consistent with our observations.

description: A minimal central bank credibility, with a non-zero probability of not renegning his commitment ("quasi-commitment"), is a necessary condition for anchoring inflation expectations and stabilizing inflation dynamics. By contrast, a complete lack of credibility, with the certainty that the policy maker will renege his commitment ("optimal discretion"), leads to the local instability of inflation dynamics. In the textbook example of the new-Keynesian Phillips curve, the response of the policy instrument to inflation gaps for optimal policy under quasi-commitment has an opposite sign than in optimal discretion, which explains this bifurcation.

description: We report a homebuilt ultra-high-vacuum (UHV) rotating sample manipulator with cryogenic cooling. The sample holder is thermally anchored to a built-in cryogenic cold head through flexible copper beryllium strips, permitting continuous sample rotation. A similar contact mechanism is implemented for the electrical wiring to the sample holder for thermometry. The apparatus thus enables continuous sample rotation at regulated cryogenic temperatures in a UHV environment. We discuss the potential applications of this apparatus for cryogenic sputtering.

description: Stellar magnetic activity provides substantial information on the magnetic dynamo and the coronal heating process. We present a catalog of X-ray activity for about 6000 stars, based on the $Chandra$ and $Gaia$ DR2 data. We also classified more than 3000 stars as young stellar objects, dwarf stars, or giant stars. By using the stars with valid stellar parameters and classifications, we studied the distribution of X-ray luminosity ($L_X$) and the ratio of X-ray-to-bolometric luminosities ($R_X$), the positive relation between $L_X$, $R_X$, and hardness ratio, and the long-term X-ray variation. This catalog can be used to investigate some important scientific topics, including the activity-rotation relation, the comparison between different activity indicators, and the activities of interesting objects (e.g., A-type stars and giants). As an example, we use the catalog to study the activity-rotation relation, and find that the young stellar objects, dwarfs, and giants fall on a single sequence in the relation $R_X$ versus Rossby number, while the giants do not follow the relation $R_X$ versus $P_{\rm rot}^{-2}R^{-4}$ valid for dwarfs.

description: Sufficiently strong inter-site interactions in extended-Hubbard and XXZ spin models result in dynamically-bound clusters at neighboring sites. We show that the dynamics of these clusters in two-dimensional lattices is remarkably different and richer than that of repulsively-bound on-site clusters in gases without inter-site interactions. Whereas on-site pairs move in the same lattice as individual particles, nearest-neighbor dimers perform an interacting quantum walk in a different lattice geometry, leading to a peculiar dynamics characterized by more than one time scale. The latter is general for any lattice geometry, but it is especially relevant in triangular and diamond lattices, where dimers move resonantly in an effective kagome and Lieb lattice, respectively. As a result, dimers experience partial quasi-localization due to an effective flat band, and may move slower than longer clusters. This surprising link between anomalously slow quantum walk dynamics in these models and flat-band physics may be readily observed in experiments with lanthanide atoms.

description: CH2 transitions between 68 and 71 GHz were first detected toward the Orion-KL and W51 Main SFRs. Given their upper level energies of 225 K, they were thought to arise in dense, hot molecular cores near newly formed stars. However, this has not been confirmed by further observations of these lines and their origin has remained unclear. Generally, there is a scarcity of observational data for CH2 and, while it is an important compound in the astrochemical context, its actual occurrence in astronomical sources is poorly constrained. The present study, along with other recent observations of the Orion region we report, rule out the possibility of an association with gas that is both hot and dense. We find that the distribution of the CH2 emission closely follows that of the [CII] 158 um emission, while CH2 is undetected toward the hot core itself. The observations suggest, rather, that its extended emission arises from hot but dilute layers of PDRs and not from the denser parts of such regions as in the case of the Orion Bar. This hypothesis was corroborated by comparisons of the observed CH2 line profiles with those of CRRLs, well-known PDR tracers. In addition, we report the detection of the 70 GHz fine- and hfs lines of o-CH2 toward the W51E, W51M, W51N, W49N, W43, W75N, DR21, and S140 SFRs, and three of the fine- and hfs lines between 68-71 GHz toward W3 IRS5. Furthermore, using a non-LTE radiative transfer analysis, we can constrain the gas temperatures and H2 density to 163 K and 3.4e3 cm^-3, respectively. This analysis confirms our hypothesis that CH2 originates in warm and dilute PDR layers. Our analysis suggests that for the excitation conditions under the physical conditions that prevail in such regions, these lines are masering, with weak level inversion. The resulting amplification of the lines' spontaneous emission greatly aids in their detection.

description: We report study of magnetization, resistivity, magnetoresistance and specific heat of the pyrochlore Iridate (Eu1-xNdx)2Ir2O7 with x=0.0, 0.5 and 1.0, where spin orbit coupling, electronic correlation, magnetic frustration and Kondo scattering coexists. Metal insulator transition temperature (T_MI) decrease with increase in Nd content but always coincides with magnetic irreversibility temperature (field induced moment). Resistivity below T_MI do not fit with either activated (gap) or to any power law (gapless) dependence. The Curie constant show surprising result, that Nd induces singlet correlation (reduction of para-moment) in Ir sublattice. Magnetoresistance is negative at low temperatures below 10 K and increases strongly with increase in x and vary quadratically with field switching over to linear dependence above 50 kOe. Low temperature specific heat shows Schottky peak, coming from Nd moments, showing existence of doublet split in Nd energy level, arising from f-d exchange interaction. All materials show presence of a linear specific heat in the insulating region. The coefficient of linear specific heat for x= 0.0 does not vary with external magnetic field but varies superlinearly for x = 1.0 materials. We argue that linear specific heat probably rules out weakly correlated phases like Weyl fermions. We propose that with the introduction of Nd at Eu site the system evolves from chiral spin liquid with gapless spinon excitations with a very small charge gap to Kondo type interaction superposed on chiral spin liquid coexisting with long range antiferromagnetic ordering. Huge increase of magnetoresistance with increase in Nd concentrations shows importance of Kondo scattering in the chiral spin liquid material by rare earth moments.

description: We present a general sufficiency condition for the presence of multipartite entanglement in thermal states stemming from the ground state entanglement. The condition is written in terms of the ground state entanglement and the partition function and it gives transition temperatures below which entanglement is guaranteed to survive. It is flexible and can be easily adapted to consider entanglement for different splittings, as well as be weakened to allow easier calculations by approximations. Examples where the condition is calculated are given. These examples allow us to characterize a minimum gapping behavior for the survival of entanglement in the thermodynamic limit. Further, the same technique can be used to find noise thresholds in the generation of useful resource states for one-way quantum computing.

description: The one-parametric Wang-Landau (WL) method is implemented together with an extrapolation scheme to yield approximations of the two-dimensional (exchange-energy, field-energy) density of states (DOS) of the 3D bimodal random-field Ising model (RFIM). The present approach generalizes our earlier WL implementations, by handling the final stage of the WL process as an entropic sampling scheme, appropriate for the recording of the required two-parametric histograms. We test the accuracy of the proposed extrapolation scheme and then apply it to study the size-shift behavior of the phase diagram of the 3D bimodal RFIM. We present a finite-size converging approach and a well-behaved sequence of estimates for the critical disorder strength. Their asymptotic shift-behavior yields the critical disorder strength and the associated correlation length's exponent, in agreement with previous estimates from ground-state studies of the model.

description: We consider the non-linear classical field theory which results from adding to the Maxwell's Lagrangian the contributions from the weak-field Euler-Heisenberg Lagrangian and a non-uniform part which involves derivatives of the electric and magnetic fields. We focus on the electrostatic case where the magnetic field is set to zero, and we derive the modified Gauss law, resulting in a higher order differential equation. This equation gives the electric field produced by stationary charges in the higher order non-linear electrodynamics. Specializing for the case of a point charge, we investigate the solutions of the modified Gauss law and calculate the correction to the Coulomb law.

description: The debate on decolonizing monuments has provoked a great deal of covering and shrouding of public sculptures. This paper looks at three examples and shows how textile interventions alter a monument’s visibility and, as products of (post)colonial trade or communal handicraft, add semantic layers. Ranging from The Kudzu Project’s marking of Confederate monuments in Charlottesville, VA, through the covering of the Robert Milligan statue by protesters in London, to a curated artwork by Joiri Minaya in Hamburg, the examples span both geographical regions and the recent history of the debate. The paper proposes that textile ephemerality questions concepts of history embedded in the traditional materiality of public sculptures and provides a model for imagining other practices of commemoration.

description: We study the propagation of solitons on complex chains built by inserting finite graphs at two sites of an unbranched chain. We compare numerical findings with the results of an analytical linear approximation scheme describing the interaction of large-fast solitons with non-local topological defects on a chain. We show that the transmission properties of the solitons strongly depend on the structure of the inserted graph, giving a tool to control the soliton propagation through the choice of pertinent graphs to be attached to the chain.

description: We present a compact \textit{in-situ} electromagnet with an active cooling system for the use in ultra-high vacuum environments. The active cooling enhances the thermal stability and increases the electric current that can be applied through the coil, promoting the generation of homogeneous magnetic fields, required for applications in real-time deposition experiments. The electromagnet has been integrated into a reflectance difference magneto-optic Kerr effect (RD-MOKE) spectroscopy system that allows the synchronous measurement of the optical anisotropy and the magneto-optic response in polar MOKE geometry. Proof of principle studies have been performed in real-time during the deposition of ultra-thin Ni films on Cu(110)-(2$\times$1)O surfaces, corroborating the extremely sharp spin reorientation transition above a critical coverage of 9 monolayers and demonstrating the potential of the applied setup for real-time and \textit{in-situ} investigations of magnetic thin films and interfaces.

description: We present the quantitative rest-frame B morphological evolution and galaxy merger fractions at 0.2 < z < 1.2 as observed by the All-wavelength Extended Groth Strip International Survey (AEGIS). We use the Gini coefficent and M_20 to identify major mergers and classify galaxy morphology for a volume-limited sample of 3009 galaxies brighter than 0.4 L_B^*, assuming pure luminosity evolution of 1.3 M_B per unit redshift. We find that the merger fraction remains roughly constant at 10 +/- 2% for 0.2 < z < 1.2. The fraction of E/S0/Sa increases from 21+/- 3% at z ~ 1.1 to 44 +/- 9% at z ~ 0.3, while the fraction of Sb-Ir decreases from 64 +/- 6% at z ~ 1.1 to 47 +/- 9% at z ~ 0.3. The majority of z < 1.2 Spitzer MIPS 24 micron sources with L(IR) > 10^11 L_sun are disk galaxies, and only ~ 15% are classified as major merger candidates. Edge-on and dusty disk galaxies (Sb-Ir) are almost a third of the red sequence at z ~ 1.1, while E/S0/Sa makeup over 90% of the red sequence at z ~ 0.3. Approximately 2% of our full sample are red mergers. We conclude (1) the galaxy merger rate does not evolve strongly between 0.2 < z < 1.2; (2) the decrease in the volume-averaged star-formation rate density since z ~ 1 is a result of declining star-formation in disk galaxies rather than a disappearing population of major mergers; (3) the build-up of the red sequence at z < 1 can be explained by a doubling in the number of spheroidal galaxies since z ~ 1.2.

description: Much smoother surfaces and significantly improved superconducting properties of relatively thick YBa2Cu3O7 (YBCO) films have been achieved by introducing a multilayered structure with alternating main YBCO and additional NdBCO layers. The surface of thick (1 microm) multilayers has almost no holes compared to YBCO films. Critical current density (Jc) have been drastically increased up to a factor > 3 in 1 microm multilayered structures compared to YBCO films over entire temperature and applied magnetic filed range. Moreover, Jc values measured in thick multilayers are even larger than in much thinner YBCO films. The Jc and surface improvement have been analysed and attributed to growth conditions and corresponding structural peculiarities.

description: We extend the formula for correlation functions of scalar field theories in terms of quantum $A_{\infty}$ algebras, presented in arXiv:2203.05366, to incorporate Dirac fields. We use a description that is analogous to string field theory, and the formula for correlation functions takes the same form for both scalar fields and Dirac fields. We prove that correlation functions from our formula satisfy the Schwinger-Dyson equations in the free theory. The proof for interacting theories is presented in the companion paper arXiv:2305.13103 by one of the authors. We also explain the relation of our formula to the definition of correlation functions in the approach by Costello and Gwilliam based on factorization algebras.

description: Recent observational studies identified a foreground stellar sub-structure traced by red clump (RC) stars (~ 12 kpc in front of the main body) in the eastern regions of the Small Magellanic Cloud (SMC) and suggested that it formed during the formation of the Magellanic Bridge (MB), due to the tidal interaction of the Magellanic Clouds. Previous studies investigated this feature only up to 4.0 deg from the centre of the SMC due to the limited spatial coverage of the data and hence could not find a physical connection with the MB. To determine the spatial extent and properties of this foreground population, we analysed data from the Gaia data release 2 (DR2) of a ~ 314 sq. deg region centred on the SMC, which cover the entire SMC and a significant portion of the MB. We find that the foreground population is present only between 2.5 deg to ~ 5-6 deg from the centre of the SMC in the eastern regions, towards the MB and hence does not fully overlap with the MB in the plane of the sky. The foreground stellar population is found to be kinematically distinct from the stellar population of the main body with ~ 35 km/s slower tangential velocity and moving to the North-West relative to the main body. Though the observed properties are not fully consistent with the simulations, a comparison indicates that the foreground stellar structure is most likely a tidally stripped counterpart of the gaseous MB and might have formed from the inner disc (dominated by stars) of the SMC. A chemical and 3D kinematic study of the RC stars along with improved simulations, including both tidal and hydro-dynamical effects, are required to understand the offset between the foreground structure and MB.

description: The generalized Langevin equation is a model for the motion of coarse-grained particles where dissipative forces are represented by a memory term. The numerical realization of such a model requires the implementation of a stochastic delay-differential equation and the estimation of a corresponding memory kernel. Here we develop a new approach for computing a data-driven Markov model for the motion of the particles, given equidistant samples of their velocity autocorrelation function. Our method bypasses the determination of the underlying memory kernel by representing it via up to about twenty auxiliary variables. The algorithm is based on a sophisticated variant of the Prony method for exponential interpolation and employs the Positive Real Lemma from model reduction theory to extract the associated Markov model. We demonstrate the potential of this approach for the test case of anomalous diffusion, where data are given analytically, and then apply our method to velocity autocorrelation data of molecular dynamics simulations of a colloid in a Lennard-Jones fluid. In both cases, the VACF and the memory kernel can be reproduced very accurately. Moreover, we show that the algorithm can also handle input data with large statistical noise. We anticipate that it will be a very useful tool in future studies that involve dynamic coarse-graining of complex soft matter systems.

description: We study the complete one-loop contributions to the chromagnetic dipole moment $Δκ$ of the top quark in the Standard Model, two Higgs doublet models, topcolor assited technicolor models (TC2), 331 models and extended models with a single extra dimension. We find that the SM predicts $Δκ= - 0.056$ and that the predictions of the other models are also consitent with the constraints imposed on $Δκ$ by low-energy precision measurements.

Adult and infant perception of an English phonetic distinction
Creators: name: Pegg, Judith E.
Publisher: name: University of British Columbia
Year: 2009

description: Previous research has revealed that very young infants discriminate most speech contrasts with which they are presented whether the contrasts are native or non-native while adults have difficulty discriminating non-native speech contrasts but easily discriminate those contrasts holding meaningful (phonemic) status in their native language. Several studies have shown that this reorganization in phonetic perception from language-general perception to language-specific perception occurs at about 10 to 12 months: infants this age attend only to native phonemic contrasts. It is of interest to determine if exposure to a phonetic variant plays an important role in influencing perception. We know from previous research that absence of exposure does not always lead to a lack of discrimination. This thesis was designed to determine if exposure per se maintains discriminability. To this end English-speaking adults and infants were tested using a phonetic distinction that does not hold phonemic status in English but does occur in English. This distinction involves the phonetic variants [da] and the stop produced following /s/ transcribed as [ta]. When tested in an identification procedure, English-speaking adults identify both [da] and (s)[ta] as members of one English phonemic category (i.e. [da]). When tested in a discrimination procedure and a category change procedure, adults discriminate (s) [ta] from [da] (albeit not as well as would be expected for a native phonemic contrast). With respect to infants, 6- to 8-month-olds discriminate this distinction revealing further support for broad-based phonetic perception at this age. However, 10- to 12-month-old infants do not discriminate, suggesting that the native phonemic status of the contrast (but not exposure) is the important factor in the reorganization. Discussion centers around how these results add to the existing literature and why infants of 10- to 12-months would fail to discriminate a native phonetic distinction.
