description: Four point functions of general N=4 1/2-BPS primary fields, satisfying the next-next-to-extremality condition Δ_{1}+Δ_{2}+Δ_{3}-Δ_{4}=4 are studied at large N and strong coupling. We apply new techniques to evaluate the effective couplings in supergravity, and confirm that the four derivative couplings arising in the five-dimensional supergravity vanish on-shell. We then show that the four point amplitude resulting from supergravity naturally splits into a "free" and an interactive part which resembles an effective quartic interaction. The precise structure agrees with superconformal symmetry and supports the conjecture formulated by Dolan, Osborn and Nirschl regarding the strongly coupled form of four point correlators of chiral primary operators. We also evaluate the amplitude in large N free field SYM theory and discuss the results in the context of the correspondence.

description: We present a three-pointing study of the molecular gas in the starburst nucleus of M82 based on 190 - 307 GHz spectra obtained with Z-Spec at the Caltech Submillimeter Observatory. We present intensity measurements, detections and upper limits, for 20 transitions, including several new detections of CS, HNC, C2H, H2CO, and CH3CCH lines. We combine our measurements with previously-published measurements at other frequencies for HCN, HNC, CS, C34S, and HCO+ in a multi-species likelihood analysis constraining gas mass, density and temperature, and the species' relative abundances. We find some 1.7 - 2.7 x 10^8 M_sun of gas with n_H2 between 1 - 6 x 10^4 cm^-3 and T > 50 K. While the mass and temperature are comparable to values inferred from mid-J CO transitions, the thermal pressure is a factor of 10 - 20 greater. The molecular interstellar medium is largely fragmented and is subject to ultraviolet irradiation from the star clusters. It is also likely subject to cosmic rays and mechanical energy input from the supernovae, and is warmer on average than the molecular gas in the massive star formation regions in the Milky Way. The typical conditions in the dense gas in M82's central kpc appear unfavorable for further star formation; if any appreciable stellar populations are currently forming, they are likely biased against low mass stars, producing a top-heavy initial mass function.

description: Measurements of the superconducting transition temperature, T_c, under hydrostatic pressure via bulk AC susceptibility were carried out on several concentrations of phosphorous substitution in BaFe_2(As_{1-x}P_x)_2. The pressure dependence of unsubstituted BaFe_2As_2, phosphorous concentration dependence of BaFe_2(As_{1-x}P_x)_2, as well as the pressure dependence of BaFe_2(As_{1-x}P_x)_2 all point towards an identical maximum T_c of 31 K. This demonstrates that phosphorous substitution and physical pressure result in similar superconducting phase diagrams, and that phosphorous substitution does not induce substantial impurity scattering.

Selling English in South Korea : the marketing of English and uses of foreigners in the English as a foreign language industry
Creators: name: DeChamplain, Jessica
Publisher: name: University of British Columbia
Year: 2017

description: This thesis examines the private English as a Foreign Language (EFL) industry in the Republic of Korea, herein called South Korea, focusing on the messages that are conveyed about the English language through hagwon advertisements and the roles and positioning of foreign (non-Korean) teachers within hagwons. I analyse the messages contained within various forms of marketing to discuss the discourses that surround the English language, foreign so-called native English speaker teachers (NESTs), and the ability of Koreans to learn the English language well, or not. This thesis discusses issues associated with the native/non-native speaker dichotomy, the native speaker fallacy, and the global spread of the English language as it pertains to the South Korean market that is incredibly education-focused and test-based, where parents and students are always seeking opportunities for social mobility. In particular, I examine how stereotypes associated with native English-speaking teachers (NESTs) and non-native English-speaking teachers (NNESTs) shape the discourses and advertising choices of hagwons. I argue that specific choices are made in advertising depending on the target age of students, and that these choices will include foreign teachers only when those involved in creating such advertisements wish to reference the positive discourses attached to them. There is also a strong association in South Korea that persists between race and language learning ability, which has long been disproven by anthropologists but is nonetheless seemingly perpetuated by marketing that continues to reference it. Finally, I explore possibilities for the future in an industry that has seen significant changes in the preceding decades, taking into account declining birth rates and increasing the English language knowledge of South Koreans.

description: We obtain magnetic black-hole solutions in arbitrary $n(\ge 4)$ even dimensions for an action given by the Einstein-Gauss-Bonnet-Maxwell-$Λ$ pieces with the $F^4$ gauge-correction terms. This action arises in the low energy limit of heterotic string theory with constant dilaton and vanishing higher form fields. The spacetime is assumed to be a warped product ${\ma M}^{2} \times {\ma K}^{n-2}$, where ${\ma K}^{n-2}$ is a $(n-2)$-dimensional Einstein space satisfying a condition on its Weyl tensor, originally considered by Dotti and Gleiser. Under a few reasonable assumptions, we establish the generalized Jebsen-Birkhoff theorem for the magnetic solution in the case where the orbit of the warp factor on ${\ma K}^{n-2}$ is non-null. We prove that such magnetic solutions do not exist in odd dimensions. In contrast, in even dimensions, we obtain an explicit solution in the case where ${\ma K}^{n-2}$ is a product manifold of $(n-2)/2$ two-dimensional maximally symmetric spaces with the same constant warp factors. In this latter case, we show that the global structure of the spacetime sharply depends on the existence of the gauge-correction terms as well as the number of spacetime dimensions.

description: Motional heating of ions in micro-fabricated traps is a challenge hindering experimental realization of large-scale quantum processing devices. Recently a series of measurements of the heating rates in surface-electrode ion traps characterized their frequency, distance, and temperature dependencies, but our understanding of the microscopic origin of this noise is still vague. In this work we develop a theoretical model for the electric field noise which is associated with a random distribution of adsorbed atoms on the trap electrode surface. By using first principle calculations of the fluctuating dipole moments of the adsorbed atoms we evaluate the distance, frequency and temperature dependence of the resulting electric field fluctuation spectrum.Our theory calculates the noise spectrum beyond the standard scenario of two-level fluctuators, by incorporating all the relevant vibrational states. The $1/f$ noise is shown to commence at roughly the frequency of the fundamental phonon transition rate and the $d^{-4}$ dependence with distance of the ion from the electrode surface is established.

title: Machine learning state evaluation in prismata
Creators: name: Campbell, Rory
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Strategy games are a unique and interesting testbed for AI protocols due their complex
 rules and large state and action spaces. Recent work in game AI has shown that
 strong, robust AI agents can be created by combining existing techniques of deep
 learning and heuristic search. Heuristic search techniques typically make use of
 an evaluation function to judge the value of a game state, however these functions
 have historically been hand-coded by game experts. Recent results have shown
 that it is possible to use modern deep learning techniques to learn these evaluation
 functions, bypassing the need for expert knowledge.
 In this thesis, we explore the implementation of this idea in Prismata, an online
 strategy game by Lunarch Studios. By generating game trace training data with
 existing state-of-the-art AI agents, we are able to use a Machine Learning (ML)
 approach to learn a new evaluation function. We trained several evaluation models
 with various parameters in order to compare prediction time with prediction accuracy.
 To evaluate the strength of our learned model, we ran a tournament between
 AI players which differ only in their state evaluation strategy. The results of this
 tournament demonstrate that our learned model when combined with the existing
 Prismata Hierarchical Portfolio Search system, produces a new AI agent which is
 able to defeat the previously strongest agents. A subset of the research presented
 in this thesis was the subject of a publication in the Artificial Intelligence and Interactive
 Digital Entertainment (AIIDE) 2019 Strategy Games Workshop [1].

description: Methods are developed for constructing spectral representations of cold (barotropic) neutron-star equations of state. These representations are faithful in the sense that every physical equation of state has a representation of this type, and conversely every such representation satisfies the minimal thermodynamic stability criteria required of any physical equation of state. These spectral representations are also efficient, in the sense that only a few spectral coefficients are generally required to represent neutron-star equations of state quiet accurately. This accuracy and efficiency is illustrated by constructing spectral fits to a large collection of "realistic" neutron-star equations of state.

description: The aim of the present study was to assess and compare the effect of increasing exercise levels of thirty-six trained Dutch Warmblood horses fed a isoenergetic high versus low fiber content on the circulating Thyroid hormones (THs): triiodothyronine (T3), thyroxine (T4), free triiodothyronine (fT3) and free thyroxine (fT4) concentrations. The training schedule was carried out in three consecutive phases, according to three exercise levels (light, medium and medium-heavy) performed on trainingsmill. Each phase lasted 4 weeks. At week 4 of each phase a standardized exercise test (SET) on treadmill was performed. Blood samples were collected at rest (baseline values), and after 15, 30 and 60 min after SET, according to different phases. Horses were randomly distinguished in two groups of 18 subjects. One group of horses was fed a high fiber diet (HF group) and one group was fed a low fiber diet (LF group). Results showed that in basal conditions diet influenced significantly fT3 values, with the highest concentration in HF, and fT4 values with the highest concentrations in LF group. The time influenced significantly THs in both groups, with the highest values at June for T3, and at October for T4, fT3 and fT4. A significant correlation between T4 and fT4 was observed in basal conditions. In exercise conditions, diet influenced only fT4 values, with thehighest concentrations in LF group. The time influenced significantlyT4 andfT4 concentrations, with the highest values at 15 min for fT4 and at 30 min for T4 values and the lowest values at 60 min for both hormones. Significant correlations between T3 and fT3, as well as T4 and fT4 were observed in exercise conditions. The evaluation of THs output, according to diet contents, could mirror a quantitative and qualitative interplay between thyroid function and increasing exercise level of trained horses.

description: Sexual health is a fundamental component of human well-being. Any disease threating human well-being may also impair both male and female sexual life. The most common “non-communicable diseases” (NCDs) in the world are strictly associated with sexual dysfunctions as they share most risk factors and pathogenetic mechanisms. Chronic low-grade inflammation, together with oxidative stress and endothelial dysfunction, represents a common predisposing pathological condition for both chronic diseases and sexual dysfunctions. Mediterranean diet, based on high intake of plant-based foods, olive oil as the main source of fat, low-to-moderate intake of fish, dairy products, and poultry, low consumption of red or processed meat, and low to- moderate consumption of wine with meals has showed several beneficial effects on cardio-metabolic and sexual health. The adoption of healthy lifestyles, including Mediterranean dietary pattern and regular physical activity helps reducing inflammation, endothelial dysfunction, and oxidative stress – all of which are desirable target to achieve for a better health and sexual life.

description: We study systems of few two-component fermions interacting via short-range interactions within a harmonic-oscillator trap. The dominant interactions, which are two-body, are organized according to the number of derivatives and defined in a two-body truncated model space made from a bound-state basis. Leading-order (LO) interactions are solved for exactly using the formalism of the No-Core Shell Model, whereas corrections are treated as many-body perturbations. We show explicitly that next-to-LO and next-to-next-to-LO interactions improve convergence as the model space increases. We present results at unitarity for three- and four-fermion systems, which show excellent agreement with the exact solution (for the three-body problem) and results obtained by others methods (in the four-body case). We also present results for finite scattering lengths and non-zero range of the interaction, including (at positive scattering length) observation of a change in the structure of the three-body ground state and extraction of the atom-dimer scattering length.

title: Selling the republican ideal: state communication in the Dutch Golden Age
Creators: name: der Weduwen, Arthur
Publisher: name: University of St Andrews
Year: 2018

description: This study seeks to describe the public communication practices of the authorities in the Dutch Golden Age. It is a study of ‘state communication’: the manner in which the authorities sought to inform their citizens, publicise their laws, and engage publicly in quarrels with their political opponents. These communication strategies underpinned the political stability of the seventeenth-century Dutch Republic. Concerned about their decorous appearance, the regents who ruled the country always understated the extent to which they relied on the consent of their citizens. The regents shared a republican ideal which dismissed the agency of popular consent; but this was an ideal, like so many ideals in the Dutch Republic, which existed in art and literature, but was not practised in daily life. The practicalities of governance demanded that the regents of the Dutch Republic adopt a sophisticated system of communication. The authorities employed town criers and bailiffs to speed through town and country to repeat proclamations; they instructed ministers to proclaim official prayer days at church; and they ensured that everywhere, on walls, doors, pillars and public boards, one could find the texts of ordinances, notices and announcements issued by the authorities. In the seventeenth-century Dutch Republic, politics was not the prerogative of the few. That this was due to the determined efforts of the authorities has never been appreciated. Far from withholding political information, the regents were finely attuned to the benefit of involving their citizens in the affairs of state. The Dutch public was exposed to a wealth of political literature, much of it published by the state. The widespread availability of government publications also exposed the law to prying, critical eyes; and it paved the way to make the state, and the bewildering wealth of legislation it communicated, more accountable.

Enhanced actuation and fabrication methods for integrated digital microfluidic systems
Creators: name: Salem, Mohamed Yafia Okba
Publisher: name: University of British Columbia
Year: 2017

description: Introducing a practical digital microfluidic (DMF) platform has been always an important goal that can facilitate and broaden the use of DMF systems in various applications on a regular basis. In particular, a desired DMF platform may be the one which is fabricated easily and is also affordable, portable, battery powered, and user friendly. It should perform DMF operations reliably, accept mass-produced replaceable chips and can be readily integrated into a post processing station as well. Accordingly, the development of a practical DMF platform with these characteristics is the main target of this research. Specifically, the research has enhanced DMF systems through i) improved and novel actuation mechanisms, ii) cost-effective rapid prototyping techniques, and iii) full system integration. First, detailed experimental and numerical characterization of droplet morphology is performed to insinuate useful design and prototyping tips for enhanced DMF devices. Since droplet transport predominantly depends on the gap height, a major objective of the thesis is understanding the motion dynamics of a droplet at different gap heights. The characterization of the droplet behaviour in different regimes led to enhancing the actuation process in DMF systems. In addition, a variable gap size actuation (VGSA) mechanism is integrated into the DMF system to optimize DMF operations including droplet transport, splitting, dispensing and merging in real time. Consequently, the DMF operations can be performed reliably by adjusting the optimum operating conditions. Second, for rapid prototyping DMF chips, a new fabrication method is presented in which the electrodes are generated using screen printing. As a batch fabrication technique, the proposed screen printing approach is advantageous to the widely reported DMF electrode fabrication methods in terms of fabrication volume, time, and cost. In addition, a laser scribing technique is introduced as a low-cost, rapid and facile method for fabricating laser scribed graphene electrodes for DMF systems. Third, an ultraportable, low-cost, and modular DMF platform was successfully integrated with a smartphone that is used as a high-level controller. A colorimetric assay for pH value detection is introduced to demonstrate the performance of the device as a microscope and a post processing station.

description: We consider the process of scattering of Galactic cosmic-ray electrons and protons off of dark matter with the radiation of a final-state photon. This process provides a novel way to search for Galactic dark matter with gamma rays. We argue that for a generic weakly interacting massive particle, barring effects such as co-annihilation or a velocity-dependent cross section, the gamma-ray emission from cosmic-ray scattering off of dark matter is typically smaller than that from dark matter pair-annihilation. However, if dark matter particles cannot pair-annihilate, as is the case for example in asymmetric dark matter scenarios, cosmic-ray scattering with final state photon emission provides a unique window to detect a signal from dark matter with gamma rays. We estimate the expected flux level and its spectral features for a generic supersymmetric setup, and we also discuss dipolar and luminous dark matter. We show that in some cases the gamma-ray emission might be large enough to be detectable with the Fermi Large Area Telescope.

Due to its compatibility with the Quantum Action Principle, the linearly broken BRST symmetry can be directly converted into a suitable set of useful Slavnov-Taylor identities. As a consequence, it turns out that the renormalization aspects of the Gribov-Zwanziger theory can be addressed by means of the cohomology of a nilpotent local operator

Consequently, the aim of this study is to describe macroscopic changes and histopathological findings documented in lung tissue of these patients. Moreover, the need of an optimised autopsy protocol and the application of ancillary techniques, such as immunohistochemistry (IlHC), in situ hybridization (ISH), PCR-based assay and electron microscopy, have to be recorded in order to assess the presence of COVID-19 virus-like particles in lung tissue, although the risk of autolytic changes as well the incorrect interpretation of artefacts should be cautiously considered.

Originally approved as monotherapy, olaparib is also approved to be administered in combination with bevacizumab in patients whose cancer is associated with homologous recombination deficiency (HRD), defined by either a BRCA1/2 mutation and/or genomic instability. In phase III trials, olaparib monotherapy significantly improved progression-free survival (PFS) relative to placebo (SOLO-1), as did olaparib plus bevacizumab relative to placebo plus bevacizumab (PAOLA-1), in patients with advanced ovarian cancer who had responded to platinum-based chemotherapy. In PAOLA-1, improvements in PFS with olaparib plus bevacizumab were not seen in patients with HRD-negative tumours relative to placebo plus bevacizumab. Both olaparib monotherapy and olaparib in combination with bevacizumab had generally manageable tolerability profiles. Olaparib, alone or in combination with bevacizumab, is a useful option for the first-line maintenance treatment of adults with HRD-positive, advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response to first-line, platinum-based chemotherapy.

description: Caustic and foreign body ingestions represent a fairly frequent occurrence in children and a major concern both for families and clinicians, as it can range from non-significant to life-threatening events, leading to severe sequelae. Despite the efforts across the years to ensure safer environment and child-proof products packages, the number of new cases remains high.Most cases occur in developing countries, where preschoolers and children are less supervised, and storage of household products is often inadequate. The purpose of this paper is to perform an updated overview of the correct approach to a child with caustic or foreign body ingestion, providing an immediate practical application for the physicians.

Induction of the antigen presentation machinery using novel small molecules

description: The immune system is crucial in the prevention and eradication of cancer. However, cancer genomes mutate more frequently than healthy cells and a commonly acquired phenotype is reduced expression of the antigen presentation machinery (APM) that is required for immunosurveillance. This phenotype can allow cancer cells to become invisible to the immune system and metastasize with limited inhibition. Since this phenomenon is seen across a wide variety of cancers discovering methods to reverse this immune evasion could lead to the development of widely applicable therapeutics. A compound, S-(+)-curcuphenol was previously identified as a novel candidate for restoring expression of the APM, however, its synthesis is greatly hindered due to chirality. Therefore, I investigated the ability of curcuphenol analogues to induce expression of the major histocompatibility complex I (MHC-I) in a murine metastatic lung carcinoma cell line in vitro. Two derivatives of curcuphenol, P02-113 and P03-97-1, showed improved outcomes in vitro and I further evaluated them in vivo, as anti-cancer therapeutics. Both compounds reduced tumour burden and increased immune cell infiltration into tumours. To explore a potential mechanism of P02-113 and P03-97-1, I evaluated them for histone deacetylase (HDAC) inhibition based on structural similarity to established HDAC inhibitors. Upon examination I observed a completely novel effect of enhanced class I/II HDAC activity. Furthermore to identify if this effect was direct and to uncover which HDAC enzymes were being affected, I evaluated individual HDAC enzymes. I discovered that HDAC8 was inhibited by both P02-113 and P03-97-1, however, the activities of HDAC 5 and 10 were enhanced upon treatment. While the field of cancer immunotherapy has grown, few therapeutics have been identified to target loss of immunogenicity through the up-regulation of the APM. In this thesis two analogues of curcuphenol P02-113 and P03-97-1 have been identified that up- regulate the APM in vitro and reduce tumour burden in vivo. With these effects P02-113 and P03-97-1 hold great potential as future therapeutics for cancers exhibiting an immunodeficient phenotype through loss of the APM. As well these compounds present ii the first class II HDAC enhancers, as they increase the enzymatic activity of HDAC 5 and 10.

description: The recent bankruptcies of large joint stock companies in U.S. and Europe shook investors across the world and underlined the importance of failure prediction both in academia and industry. It now seems more necessary than ever to develop early warning systems that can help to prevent or avert corporate default. These systems facilitate the selection of firms to collaborate with or invest in.
title: ‘Not my kind of food’: Dietary polarisation on the transition towards sustainable diets
Creators: name: Davis, Tessa Abigail
Publisher: name: University of Glasgow
Year: 2023

description: Across 3 pre-registered projects, we analysed the relationship between food representations and dietary behaviour to better understand why shifting towards sustainable diets is so difficult. Specifically, we investigated how polarised omnivores and vegans cognitively represent and publicly present meat and plant-based foods. For each project, food descriptions were coded according to whether they contained features about consuming and enjoying food (e.g. ‘rich’, ‘indulgent’, ‘treat’), or to aspects independent of the consumption situation (e.g. ‘healthy’, ‘protein’, ‘eco-friendly’). In Project 1 (NStudy1 = 852; NStudy2 = 3104), Instagram posts about meat foods were described in hashtags with more rewarding consumption language than posts about plant-based foods, which were instead described with more situation independent language – especially identity-focused discourse (e.g. ‘vegan community’). In Project 2 (NExp. 1 = 220; NExp. 2 = 843), participants described ingroup foods (meat dishes for omnivores; plant-based dishes for vegans) with more rewarding consumption features than outgroup foods (plant-based dishes for omnivores; meat dishes for vegans). In contrast, omnivores used more situation independent features for outgroup foods, and vegans more social and political context language (e.g. ‘animal abuse’). In Project 3 (NExp. 1 = 82; NExp. 2 = 913), when trying to make a plant-based dish appealing to omnivores in a hypothetical social media setting, participants used more rewarding consumption language than when appealing to vegans. Despite people thinking about in-group foods in terms of rewarding consumption, plant-based foods are not publicly described in this way, even by vegans. As reward expectations drive food choices, this typical presentation of plant-based foods can hinder mainstream consumer transitions towards sustainable food choices and strengthen dietary group polarisation.
title: Eigenvalue Optimization with respect to Shape‐Variations in Electromagnetic Cavities

description: The article considers the optimization of eigenvalues in electromagnetic cavities by means of shape variations. The field distribution and its frequency in a radio‐frequency cavity are governed by Maxwell's eigenvalue problem. To this end, we utilize a mixed formulation by Kikuchi (1987) and a mixed finite element discretization by means of Nédélec and Lagrange elements. The shape optimization is based on the method of mappings, where a Piola transformation is utilized to assert conformity of the mapped spaces. We derive the derivatives by the use of adjoint calculus for the constraining Maxwell eigenvalue problem. In two numerical examples, we demonstrate the functionality of this method.

description: An adiabatic cycle of parameters in a quantum system can yield the quantum anholonomies, nontrivial evolution not just in phase of the states, but also in eigenvalues and eigenstates. Such exotic anholonomies imply that an adiabatic cycle rearranges eigenstates even without spectral degeneracy. We show that an arbitrarily large quantum circuit generated by recursive extension can also exhibit the eigenvalue and eigenspace anholonomies.

Effect of genistein on the expression of testicular steroidogenic and drug-metabolizing enzymes in adult male Sprague-Dawley rats

description: There is increasing concern that human exposure to endocrine disruptors with estrogenic activities can adversely affect male reproductive health. Genistein is a plant-derived xenoestrogen that exhibits the ability to bind to estrogen receptors. Humans are exposed to genistein through the consumption of soybeans and processed soy products. The present study aims to investigate on the effect of genistein on the expression of testicular steroidogenic and drug-metabolizing enzymes. Thirty-seven adult male Sprague-Dawley rats were randomized into 6 groups and received vehicle (10%DMSO/90%PEG-400, v/v), genistein at 4, 40 or 400 μmol/kg/day, bisphenol A (BPA) at 200 μmol/kg/day or 17β-estradiol benzoate (EB) at 0.4 μmol/kg/day, subcutaneously, for 14 days. One day after the last treatment, rats were killed, their liver and testes were immediately excised and weighed, and the blood was collected. Body weight gain during the treatment period and serum testosterone levels were measured. Expression of CYP1B1, CYP2A1, CYP17A1, microsomal epoxide hydrolase (mEH), CYP oxidoreductase (POR), and 3β-hydroxysteroid dehydrogenase (HSD3β) in testicular microsomes was determined by immunoblot analysis. Histological examination of testis was performed by immunohistochemical analysis and H&E staining. The results showed that treatment with genistein did not affect body weight gain but treatment with BPA or EB decreased body weight gain relative to the vehicle-treated group. Liver and testis weights and serum testosterone levels were unaffected by treatment with genistein, BPA or EB. Testicular protein levels of CYP2A1, CYP17A1 and mEH but not HSD3β were decreased following treatment with genistein at 40 or 400 μmol/kg/day, BPA at 200 μmol/kg/day or EB at 0.4 μmol/kg/day. Testicular POR expression was decreased at the highest dosage of genistein (400 μmol/kg/day), BPA or EB. Testicular CYP1B1 protein levels appeared to decrease in response to treatment with genistein or BPA, but the differences, when compared to vehicle group, were not statistically significant. The testicular CYP1B1 protein level was reduced following treatment with EB. No histological changes were seen in testis regardless of the treatment given. In summary, genistein selectively suppressed expression of testicular CYP2A1, CYP17A1, mEH and POR enzymes without altering the histology of testis in adult male rats.

description: We have investigated charge dynamics and electronic structures for single crystals of metallic layered nickelates, R2-xSrxNiO4 (R=Nd, Eu), isostructural to La2-xSrxCuO4. Angle-resolved photoemission spectroscopy on the barely-metallic Eu0.9Sr1.1NiO4 (R=Eu, x=1.1) has revealed a large hole surface of x2-y2 character with a high-energy pseudogap of the same symmetry and comparable magnitude with those of underdoped (x<0.1) cuprates, although the antiferromagnetic interactions are one order of magnitude smaller. This finding strongly indicates that the momentum-dependent pseudogap feature in the layered nickelate arises from the real-space charge correlation.

description: We present a reliable algorithm to evaluate quantum discord for general two--qubit states, amending and extending an approach recently put forward for the subclass of X--states. A closed expression for the discord of arbitrary states of two qubits cannot be obtained, as the optimization problem for the conditional entropy requires the solution to a pair of transcendental equations in the state parameters. We apply our algorithm to run a numerical comparison between quantum discord and an alternative, computable measure of non-classical correlations, namely the geometric discord. We identify the extremally non-classically correlated two--qubit states according to the (normalized) geometric discord, at fixed value of the conventional quantum discord. The latter cannot exceed the square root of the former for systems of two qubits.
