description: We systematically study the extension of the Supersymmetric Standard Model (SSM) by an anomaly-free discrete gauge symmetry Z_N. We extend the work of Ibanez and Ross with N=2,3 to arbitrary values of N. As new fundamental symmetries, we find four Z_6, nine Z_9 and nine Z_18. We then place three phenomenological demands upon the low-energy effective SSM: (i) the presence of the mu-term in the superpotential, (ii) baryon-number conservation upto dimension-five operators, and (iii) the presence of the see-saw neutrino mass term LHLH. We are then left with only two anomaly-free discrete gauge symmetries: baryon-triality, B_3, and a new Z_6, which we call proton-hexality, P_6. Unlike B_3, P_6 prohibits the dimension-four lepton-number violating operators. This we propose as the discrete gauge symmetry of the Minimal SSM, instead of R-parity.

description: The pressure dependence of the critical temperature $T_c$ and upper critical field $H_{c2}(T)$ has been measured up to 19 GPa in the layered superconducting material 2H-NbSe$_2$. Relating the behavior of $H_{c2}(T)$ to Fermi surface parameters, we find that the electron phonon coupling of the 2D Nb 4d derived bands shows a peak at 5 GPa when the charge density wave (CDW) order is suppressed. On the other hand, $T_c(P)$ shows a bell shaped curve with a maximum at 10.5 GPa, well above the pressure for the suppression of the CDW order. Changes in the band structure produce this shift in the maximum of $T_c(P)$, demonstrating that 2H-NbSe$_2$ shows important differences with respect to other compounds where $T_c$ has a maximum in the temperature-density phase diagram shaped by the suppression of another, non-superconducting, ground state.

description: Reducing measurement errors in multi-qubit quantum devices is critical for performing any quantum algorithm. Here we show how to mitigate measurement errors by a classical post-processing of the measured outcomes. Our techniques apply to any experiment where measurement outcomes are used for computing expected values of observables. Two error mitigation schemes are presented based on tensor product and correlated Markovian noise models. Error rates parameterizing these noise models can be extracted from the measurement calibration data using a simple formula. Error mitigation is achieved by applying the inverse noise matrix to a probability vector that represents the outcomes of a noisy measurement. The error mitigation overhead, including the the number of measurements and the cost of the classical post-processing, is exponential in $εn$, where $ε$ is the maximum error rate and $n$ is the number of qubits. We report experimental demonstration of our error mitigation methods on IBM Quantum devices using stabilizer measurements for graph states with $n\le 12$ qubits and entangled 20-qubit states generated by low-depth random Clifford circuits.

description: We consider a class of one-dimensional chains of weakly coupled many level systems. We present a theory which predicts energy diffusion within these chains for almost all initial states, if some concrete conditions on their Hamiltonians are met. By numerically solving the time dependent Schroedinger equation, we verify this prediction. Close to equilibrium we analyze this behavior in terms of heat conduction and compute the respective coefficient directly from the theory.

How to be ordinary: To what extent do normative narratives of the family influence the friendship-making practices of female same-sex parents?
Creators: name: Hooley, Zara
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: As Finch and Mason (1999) and Morgan (1996) assert, studies of intimate family life can reveal wider patterns of social change. In their 2002 monograph on LGBT families, Weeks et al investigated how LGBT individuals constructed families within the context of significant changes in the cultural and political landscape of everyday life. They discuss the non-heterosexual family as pioneers of “experiments in living” (2002, p.vii), who have impacted on traditional notions of family, and pushed the boundaries of acceptable formulations of kinship and intimacy. At a similar time, Beck and Beck-Gernsheim (2002) and Giddens (1991) were suggesting that there has been a shift away from normative family models rooted in a relationship to economic capital and reproduction. This shift away from traditional family forms has often been used as evidence to suggest that structural understandings of normative behaviour are being unravelled and that a more progressive and liberal understanding of family is emerging (Silva and Smart, 1999).In this research, I use the setting of friendship-making post-transition to parenting to challenge the ideas above. By examining how friendly connections to others were made, it was possible to investigate when female same-sex parents were allowed to feel ordinary and included in parenting spaces.I conducted this research taking a qualitative approach, interviewing parents in 12 households. This led to 23 individual semi-structured interviews, and 10 follow-up couple interviews. I asked participants to draw metaphorical maps of their social worlds, and used these maps as stimulus during the interview process.This research extends the literature on how LGBTQ+ people experience the social spaces and social support around parenting (Taylor 2009b; Woodford et al. 2010; Ryan-Flood 2005; Hicks and McDermott 1999; Speziale and Gopalakrishna 2004; Gabb 2008; Gartrell et al. 1996, 1999, 2000 and 2005). In this thesis I challenge the idea of a loosening of normative models of family, by providing evidence of the importance of the structural binds of gender in the formation of the social networks of female same-sex parents. Far from the proliferation of identities discussed by Giddens (1991); mothers in this study demonstrate that their marginalised positions in relation to genetic connection, birth giving status and dual motherhood are still operating within highly gendered constraints.

description: The so-called Mixed Feedback Loop (MFL) is a small two-gene network where protein A regulates the transcription of protein B and the two proteins form a heterodimer. It has been found to be statistically over-represented in statistical analyses of gene and protein interaction databases and to lie at the core of several computer-generated genetic networks. Here, we propose and mathematically study a model of the MFL and show that, by itself, it can serve both as a bistable switch and as a clock (an oscillator) depending on kinetic parameters. The MFL phase diagram as well as a detailed description of the nonlinear oscillation regime are presented and some biological examples are discussed. The results emphasize the role of protein interactions in the function of genetic modules and the usefulness of modelling RNA dynamics explicitly.

description: The open charm strong decay widths and certain ratio of branching fractions of a charmed strange baryon $Ξ_c(2970)$ are calculated in a $^3P_0$ model. The results are compatible with the latest experimental data. The theoretical ratio of decay branching fractions $R = \mathcal{B} [ Ξ_{c}(2970)^+ \rightarrow Ξ_c(2645)^{0}π^{+} ] / \mathcal{B} [ Ξ_{c}(2970)^+ \rightarrow Ξ_c^{\prime0}π^{+}] \approx 1.0$. The spin-parity $J^P = 1/2^+$ and $3/2^+$ for different assignments are analyzed. From the results of our calculation, $Ξ_{c}(2970)$ can be interpreted as a $2S$-wave state with $J^P(s_l) = 1/2^+(0)$. The distinguishing between the 2S-wave $n_ρ$- and $n_λ$-excitation states and between states with $s_l = 0$ and $s_l = 1$ and between states with total spin $1/2$ and $3/2$($s_l = 1$) are also discussed.

description: A phenomenological analysis of the distribution of Wilson loops in SU(2) Yang-Mills theory is presented in which Wilson loop distributions are described as the result of a diffusion process on the group manifold. It is shown that, in the absence of forces, diffusion implies Casimir scaling and, conversely, exact Casimir scaling implies free diffusion. Screening processes occur if diffusion takes place in a potential. The crucial distinction between screening of fundamental and adjoint loops is formulated as a symmetry property related to the center symmetry of the underlying gauge theory. The results are expressed in terms of an effective Wilson loop action and compared with various limits of SU(2) Yang-Mills theory.

description: Photoelectron momentum microscopy is an emerging powerful method for angle-resolved photoelectron spectroscopy (ARPES), especially in combination with imaging spin filters. These instruments record kx-ky images, typically exceeding a full Brillouin zone. As energy filters double-hemispherical or time-of-flight (ToF) devices are in use. Here we present a new approach for momentum mapping of the full half-space, based on a single hemispherical analyzer (path radius 225 mm). Excitation by an unfocused He lamp yielded an energy resolution of 7.7 meV. The performance is demonstrated by k-imaging of quantum-well states in Au and Xe multilayers. The alpha-square-aberration term (alpha: entrance angle in the dispersive plane) and the transit-time spread of the electrons in the spherical field are studied in a large pass-energy (6 to 660 eV) and angular range (alpha up to about 7°). It is discussed how the method circumvents the preconditions of previous theoretical work on the resolution limitation due to the alpha-square-term and the transit-time spread, being detrimental for time-resolved experiments. Thanks to k-resolved detection, both effects can be corrected numerically. We introduce a dispersive-plus-ToF hybrid mode of operation, with an imaging ToF analyzer behind the exit slit of the hemisphere. This instrument captures 3D data arrays I(EB,kx,ky), yielding a gain up to N^2 in recording efficiency (N being the number of resolved time slices). A key application will be ARPES at sources with high pulse rates like Synchrotrons with 500 MHz time structure.

description: We report on magnetic properties of cubic compound Cu3TeO6 studied by $ac$ and $dc$ susceptibility and neutron powder diffraction for the first time. A novel magnetic lattice, three dimensional spin web, composed of almost planar regular hexagons of Cu2+, S =1/2 spins, defines the properties of Cu3TeO6. The behavior of the magnetic susceptibility in the paramagnetic state at approximately 170 K is suggestive for a competition between local anisotropies of Cu2+ hexagons. The resulting frustration is weaker than the antiferromagnetic nearest-neighbor interaction which leads to a collinear (or slightly canted) spin arrangement (k=0,0,0) and formation of magnetic domains below TN=61 K.

description: We present a set of long-range Bethe ansatz equations for open quantum strings on AdS_5 x S^5 and demonstrate that they diagonalize bosonic su(2) and sl(2) sectors of the theory in the near-pp-wave limit. Results are compared with energy spectra obtained by direct quantization of the open string theory, and we find agreement in this limit to all orders in the 't Hooft coupling lambda = g_YM^2 N_c. We also propose long-range Bethe ansaetze for su(2) and sl(2) sectors of the dual N=2 defect conformal field theory. In accordance with previous investigations, we find exact agreement between string theory and gauge theory at one- and two-loop order in lambda, but a general disagreement at higher loops. It has been conjectured that the sudden mismatch at three-loop order may be due to long-range interaction terms that are lost in the weak coupling expansion of the gauge theory dilatation operator. These terms are thought to include interactions that wrap around gauge-traced operators, or around the closed-string worldsheet. We comment on the role these interactions play in both open and closed sectors of string states and operators near the pp-wave/BMN limit of the AdS/CFT correspondence.

description: Hard X-ray properties of beamed AGN have been published in the 105-month Swift/BAT catalog, but there have not been any studies carried out so far on a well-defined, radio-selected sample of low-peaked blazars in the hard X-ray band. Using the statistically complete MOJAVE-1 sample, we aim to determine the hard X-ray properties of radio-selected blazars, including the enigmatic gamma-ray-faint type. Also, we aim to determine the contribution of radio-selected low-peaked blazars to the diffuse CXB. We determined photon indices, fluxes, and luminosities in the range of 20 keV - 100 keV of blazars and other extragalactic jets from the MOJAVE-1 sample, derived from the 105-month Swift/BAT survey. We calculated log N-log S distributions and the luminosity functions. The majority of the MOJAVE-1 blazars are found to be hard X-ray emitters albeit many at low count rates. The log N-log S distribution for the hard X-ray emission of radio-selected blazars is clearly non-Euclidean, in contrast to the radio flux density distribution. Approximately 0.2% of the CXB in the 20 keV - 100 keV band can be resolved into MOJAVE-1 blazars. The peculiar log N-log S distribution disparity might be attributed to different evolutionary paths in the X-ray and radio bands, as tested by luminosity-function modeling. X-ray variability can be ruled out as the dominant contributor. Low-peaked blazars constitute an intrinsically different source population in terms of CXB contribution compared to similar studies of X-ray-selected blazars. The hard X-ray flux and spectral index can serve as a good proxy for the gamma-ray detection probability of individual sources. Future observations combining deep X-ray survey, for example, with eROSITA, and targeted gamma-ray observations with CTA can benefit strongly from the tight connection between these high-energy bands for the different blazar sub-classes.

description: Multi-Stable Equilibrium Systems are mechanical systems, possibly composed of subsystems described by other energy domains (i.e. electrical, magnetic, chemical, hydraulic, pneumatic, etc.), that has more than one statically stable equilibrium state. A stable equilibrium is defined as a state in which the system has minimum potential energy. The key aspect of the MSE systems is that they can act as passive structures for the vast majority of time, only requiring actuation to move among stable positions or about the current equilibrium point. This characteristic feature of MSE systems puts it into a unique position of advantage to be used in fulfilling the designers’ requirement within the constraints of available energy and space. They give a great variety and flexibility to the designer to come up with more novel and efficient designs. MSE systems find many applications in the area of Micro-Electro Mechanical Systems (MEMS), especially in optical fibers. The heuristic and stochastic search algorithms used in automating the synthesis of such complex systems are capable of searching large areas in short period of time within the constraints of the problem as a part of design automation methodology. This thesis proposes a system to generate compliant multi-stable equilibrium devices using concepts of topological optimization. The software developed produces very interesting results and promises to be a great start for a field of immense potential

We spatially resolve the central region which consists of three prominent molecular emission cores. A hypercompact (HC) H$_{\rm {II}}$ region (Core A) and two molecule-rich cores (Core B and Core C) are identified using the moment zero images of the H30$α$ line and a CH$_{3}$OH line, respectively. Various oxygen-bearing complex organic molecules (COMs), such as (CH$_{3}$)$_{2}$CO and CH$_{3}$OCHO, have been detected toward the positions of Core B and Core C, while nitrogen-bearing species, CH$_{3}$CN, HC$_{3}$N and its $^{13}$C isotopologues, have been detected toward all of the cores. We discuss the formation mechanisms of H$_{2}$CO by comparing the spatial distribution of C$^{18}$O with that of H$_{2}$CO. The $^{33}$SO emission, on the other hand, shows a ring-like structure surrounding Core A, and it peaks on the outer edge of the H30$α$ emission region. These results imply that SO is enhanced in a shock produced by the expanding motion of the ionized region.

description: Multi-peaked localized stationary solutions of the discrete nonlinear Schrodinger (DNLS) equation are presented in one (1D) and two (2D) dimensions. These are excited states of the discrete spectrum and correspond to multi-breather solutions. A simple, very fast, and efficient numerical method, suggested by Aubry, has been used for their calculation. The method involves no diagonalization, but just iterations of a map, starting from trivial solutions of the anti-continuous limit. Approximate analytical expressions are presented and compared with the numerical results. The linear stability of the calculated stationary states is discussed and the structure of the linear stability spectrum is analytically obtained for relatively large values of nonlinearity.

description: Domain adaptation aims to transfer knowledge from a domain with adequate labeled samples to a domain with scarce labeled samples. Prior research has introduced various open set domain adaptation settings in the literature to extend the applications of domain adaptation methods in real-world scenarios. This paper focuses on the type of open set domain adaptation setting where the target domain has both private ('unknown classes') label space and the shared ('known classes') label space. However, the source domain only has the 'known classes' label space. Prevalent distribution-matching domain adaptation methods are inadequate in such a setting that demands adaptation from a smaller source domain to a larger and diverse target domain with more classes. For addressing this specific open set domain adaptation setting, prior research introduces a domain adversarial model that uses a fixed threshold for distinguishing known from unknown target samples and lacks at handling negative transfers. We extend their adversarial model and propose a novel adversarial domain adaptation model with multiple auxiliary classifiers. The proposed multi-classifier structure introduces a weighting module that evaluates distinctive domain characteristics for assigning the target samples with weights which are more representative to whether they are likely to belong to the known and unknown classes to encourage positive transfers during adversarial training and simultaneously reduces the domain gap between the shared classes of the source and target domains. A thorough experimental investigation shows that our proposed method outperforms existing domain adaptation methods on a number of domain adaptation datasets.

description: In an effort to counteract adverse consumer reaction to genetically engineered foods, the biotechnology industry has shifted attention to deriving and promoting foods that have been genetically modified to have benefits for the consumer. However, is it uncertain whether this strategic shift will be successful at changing consumer perception of biotechnology. To provide an initial investigation into the issue, we surveyed 270 Mississippi State students. Results suggest that these consumers were more accepting of corn chips that had been modified to increase shelf life as opposed to increasing farmer yields; however, willingness-to-pay premiums for these value-added corn chips were extremely small relative to corn ships that contained no genetically engineered corn. Results also suggest students were more accepting of genetically engineered foods when sold by agribusinesses with high levels of brand equity or store loyalty.

description: This paper studies the dynamical evolution of young stellar clusters with $N$ = 100 - 1000 members. We use N-body simulations to explore how evolution depends on system size $N$ and the initial conditions. Motivated by recent observations of extremely young systems, this study compares subvirial and virial starting states. Multiple realizations of equivalent cases (100 simulations per case) are used to build up a robust statistical description of these systems, e.g., distributions of closest approaches, mass profiles, and distributions of radial locations. These results provide a framework from which to assess the effects of these clusters on star and planet formation. The distributions of radial positions are used in conjunction with distributions of FUV luminosities (also calculated here) to determine the radiation exposure of circumstellar disks. The distributions of closest approaches are used in conjunction with scattering cross sections (calculated here from $10^5$ scattering experiments) to determine the probability of solar system disruption. We also use the nearby cluster NGC 1333 as a test case. Our main conclusion is that clusters in this size range have only a modest effect on forming planetary systems: Interaction rates are low so that the typical solar system experiences a single encounter within 1000 AU. Radiation exposure is low, with median FUV flux $G_0$ = 900, so that photoevaporation of disks is only important beyond 30 AU. Given the low interaction rates and modest radiation levels, we suggest that solar system disruption is a rare event in these clusters.

description: Abstract: The historical development of media and communication is a complex and multifaceted process reflecting changes in socio-economic, political and technological conditions. This development began with ancient forms of information transmission, such as oral storytelling and handwritten documents. The invention of the printing press by Johannes Gutenberg in the mid-15th century was a revolutionary step that ushered in the era of mass production of books and newspapers, greatly expanding access to information. In the 19th century, the telegraph and telephone made a qualitative leap in the speed and scope of communication, allowing messages to be transmitted over long distances in a matter of minutes.

description: Graph representation learning has emerged as a powerful technique for addressing real-world problems. Various downstream graph learning tasks have benefited from its recent developments, such as node classification, similarity search, and graph classification. However, prior arts on graph representation learning focus on domain specific problems and train a dedicated model for each graph dataset, which is usually non-transferable to out-of-domain data. Inspired by the recent advances in pre-training from natural language processing and computer vision, we design Graph Contrastive Coding (GCC) -- a self-supervised graph neural network pre-training framework -- to capture the universal network topological properties across multiple networks. We design GCC's pre-training task as subgraph instance discrimination in and across networks and leverage contrastive learning to empower graph neural networks to learn the intrinsic and transferable structural representations. We conduct extensive experiments on three graph learning tasks and ten graph datasets. The results show that GCC pre-trained on a collection of diverse datasets can achieve competitive or better performance to its task-specific and trained-from-scratch counterparts. This suggests that the pre-training and fine-tuning paradigm presents great potential for graph representation learning.

description: Current deep-learning based methods do not easily integrate to clinical protocols, neither take full advantage of medical knowledge. In this work, we propose and compare several strategies relying on curriculum learning, to support the classification of proximal femur fracture from X-ray images, a challenging problem as reflected by existing intra- and inter-expert disagreement. Our strategies are derived from knowledge such as medical decision trees and inconsistencies in the annotations of multiple experts, which allows us to assign a degree of difficulty to each training sample. We demonstrate that if we start learning "easy" examples and move towards "hard", the model can reach a better performance, even with fewer data. The evaluation is performed on the classification of a clinical dataset of about 1000 X-ray images. Our results show that, compared to class-uniform and random strategies, the proposed medical knowledge-based curriculum, performs up to 15% better in terms of accuracy, achieving the performance of experienced trauma surgeons.

description: Wine producers have their products evaluated at various wine exhibitions for the purpose of receiving awards that can be displayed on the bottles. This contribution introduces an approach to estimate optimal prices for wine exhibition awards. A case study has been employed in cooperation with a major Czech wine company to investigate the practical usefulness of the method. Estimating the relative importance of selected wine exhibitions as award origins and determining the partial utilities of selected awards (medals) is based on a conjoint experiment. Price equivalents and markups can be derived based on consumer preferences.

description: In this work, we introduce a three-stroke quantum engine with a single-qubit work-ing substance whose cycle consists of two strokes arise due to performing two distinctgeneral quantum measurements and it is completed by thermalization through contactwith a finite temperature thermal reservoir. It is demonstrated that energy is importedinto the engine by first measurement channel and work (usefulenergy) is extracted fromit, in a frictionless isentropic manner, by the second measurement channel. It is par-ticularly shown that the engine is capable to have perfect efficiency. In continuation,we equip the the engine cycle with two additional adiabatic strokes. As illustrated,the presence of adiabatic strokes in the cycle provide an improved lower bound for theparametrized efficiency range of the engine.

description: Over the past decade, the private sector has rapidly built up an array of private food standards to assure quality and safety in a fiercely competitive market. These private standards have sometimes been to fill in for missing public standards, especially for safety, and to differentiate products and build reputation, for both quality and safety. Moreover, private standards are increasingly related to meta-management systems assuring both quality and safety at all levels of a chain, enforcing and certifying the implementation of process standards. The privatization of standards has been important for both buyers and suppliers in the chain. They tend to be formulated and imposed by buyers (retailers and processors), and are key to their cost control and reputation with consumers, thus overall competitiveness. They are imposed on suppliers, who often find that the standards imply very substantial outlays for reporting, new equipment, and training. The lucky - a relatively small subset of the original set of suppliers - tend to find that meeting the standards, with formal certification in hand, benefits their business, opens new opportunities. The excluded tend to find themselves relegated to waning and unprofitable markets. The above points concerning the determinants and effects of the formulation and implementation of private standards are illustrated with cases from the dairy, coffee, wheat products, and coconut product chains in Brazil.

description: It has been recently shown that the electroweak baryogenesis mechanism is feasible in Standard Model extensions containing extra fermions with large Yukawa couplings. We show here that the lightest of these fermionic fields can naturally be a good candidate for cold dark matter. We find regions in the parameter space where the thermal relic abundance of this particle is compatible with the dark matter density of the Universe as determined by the WMAP experiment. We study direct and indirect dark matter detection for this model and compare with current experimental limits and prospects for upcoming experiments. We find, contrary to the standard lore, that indirect detection searches are more promising than direct detection ones, and they already exclude a portion of the parameter space.

description: Conjoint analysis was used to explore consumer preferences for food products that are the product of genetically modified organisms (GMOs). The results of a cluster analysis indicated that consumers fell into three homogeneous groups based on their preference for a branded, low-priced, or GMO-free product. There were some differences between the segments based on the sociodemographic characteristics of age, education, and income. However, consumers in the segment that wished to avoid GMOs were most easily distinguished from consumers in the other two segments based on their high level of risk averseness and belief that GMOs do not positively affect the quality or safety of food products. Implications for food marketers and policymakers are discussed.
