description: Using Landau level spectroscopy, we determine the temperature dependence of the energy band gap in zirconium pentatelluride (ZrTe$_5$). We find that the band gap reaches $E_g=(5 \pm 1)$ meV at low temperatures and increases monotonously when the temperature is raised. This implies that ZrTe$_5$ is a weak topological insulator, with non-inverted ordering of electronic bands in the center of the Brillouin zone. Our magneto-transport experiments performed in parallel show that the resistivity anomaly in ZrTe$_5$ is not connected with the temperature dependence of the band gap.

description: We develop and apply the position angle-only shear estimator of Whittaker et al. (2014) to realistic galaxy images. This is done by demonstrating the method on the simulations of the GREAT3 challenge (Mandelbaum et al. 2014b), which include contributions from anisotropic PSFs. We measure the position angles of the galaxies using three distinct methods - the integrated light method, quadrupole moments of surface brightness, and using model-based ellipticity measurements provided by IM3SHAPE. A weighting scheme is adopted to address biases in the position angle measurements which arise in the presence of an anisotropic PSF. Biases on the shear estimates, due to measurement errors on the position angles and correlations between the measurement errors and the true position angles, are corrected for using simulated galaxy images and an iterative procedure. The properties of the simulations are estimated using the deep field images provided as part of the challenge. A method is developed to match the distributions of galaxy fluxes and half-light radii from the deep fields to the corresponding distributions in the field of interest. We recover angle-only shear estimates with a performance close to current well-established model and moments-based methods for all three angle measurement techniques. The Q-values for all three methods are found to be Q~400. The code is freely available online at http://www.jb.man.ac.uk/~mbrown/angle_only_shear/.

description: Transition metal nitrides (TMNs) exhibit fascinating physical properties that hold great potential in future device applications. To stack two-dimensional TMNs with other functional materials that have dissimilar orientations and symmetries requires to separate epitaxial TMNs from the growth substrates. However, the lattice constants of TMNs are not compatible with those of most sacrificial layers, leading to a great challenge to fabricate high-quality single crystalline TMN membranes. In this letter, we report the application of a water-soluble BaO sacrificial layer as a general approach to create freestanding TMN membranes. Taken CrN as an example, the relatively small lattice mismatch and identical cubic structure between BaO and CrN ensure the growth of heterostructures. Millimeter-size CrN membrane allows us to directly observe the planar-view of atomic structure and to correlate its electronic state with intrinsic transport properties. Our work provides the opportunity to fabricate freestanding TMN membranes and the ability to transfer them to arbitrary substrates. The integration of TMN membranes with other materials will stimulate further studies in the emergent phenomena at heterointerfaces.

The lifespan for 3-dimensional quasilinear wave equations in exterior domains
Creators: name: Metcalfe, Jason
name: Helms, John
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Abstract This article focuses on long-time existence for quasilinear wave equations with small initial data in exterior domains. The nonlinearity is permitted to fully depend on the solution at the quadratic level, rather than just the first and second derivatives of the solution. The corresponding lifespan bound in the boundaryless case is due to Lindblad, and Du and Zhou first proved such long-time existence exterior to star-shaped obstacles. Here we relax the hypothesis on the geometry and only require that there is a sufficiently rapid decay of local energy for the linear homogeneous wave equation, which permits some domains that contain trapped rays. The key step is to prove useful energy estimates involving the scaling vector field for which the approach of the second author and Sogge provides guidance.
Revisiting thermodynamic topologies of black holes

description: In the generalized off-shell free energy landscape, black holes can be treated as thermodynamic topological defects. The local topological properties of the spacetime can be reflected by the winding numbers at the defects, while the global topological nature can be classified by the topological number which is the sum of all local winding numbers. We propose that the winding numbers can be calculated via the residues of isolated one-order pole points of characterized functions constructed from the off-shell free energy. Using the residue method, we show that the topologies of black holes can be divided into three classes with the topological numbers being -1, 0, and 1, respectively, being consistent with the results obtained in [Phys. Rev. Lett. 129, 191101 (2022)] by using the topological current method. Moreover, we point out that standard defect points, generation and annihilation points, and critical points can be distinguished by coefficients of the Laurent series of the off-shell characterized function at those singular points.

title: Practices of care in the recovery assemblage: an empirical study of drug services in Liverpool and Athens
Creators: name: Theodoropoulou, Eleni

description: Practices of care in the recovery assemblage: an empirical study of drug services in Liverpool and Athens Author: Eleni Theodoropoulou This thesis empirically explores the practices of care emerging in two drug recovery services: Genie in the Gutter (Liverpool) and 18 ano (Athens). Thinking with the Deleuzo-Guattarian assemblage, I follow the flows of the service-users’ desires, from their initial encounter with substances to the transformations enabled through their encounter with the recovery assemblage. Throughout this complex and non-linear narrative, the focus is not on the consumption of substances, nor on abstention, but on the body’s desire to increase its power of acting, and accordingly on the encounters and connections that enhance or block the flow of this desire. Following this line of thought, I argue that it is not the lack of the substance that holds the recovery assemblage together, but the production of connections that enhance a body’s power of acting. Therefore, recovery becomes a practice of collective care, entangled with a body’s capacity to affect and be affected. The oral (interviews) and visual (photovoice) methods deployed are connection-building devices, specifically producing, enhancing and accounting for the connection built between the two fieldsites, between the researcher and the services, and the researcher and the service-users. The data produced drive the unpacking of the human and nonhuman encounters that constitute the recovery assemblage in all its complexity. Overall, the aim of this thesis is to methodologically and empirically demonstrate that policy can be practised otherwise. The outcome of the analysis of the lived experiences of the service-users is a call for the dismissal of policy as an intervention coming from outside, and its reconstitution as a practice, emerging organically through the affective relations produced inside the recovery assemblage. I argue that the practices of care unfolded in this account are policy in practice. Furthermore, by closely attending to the affective relationships produced in the recovery assemblage, we can enhance our understanding of drug using realities, of the desires invested in drug use and recovery, and of the ways in which societies fail those whose desires clash with established systems of thought. Finally, this thesis contributes to the sociology of health and illness by expanding the body of work that mobilises Deleuze to empirically challenge wellbeing as a stable state and individual matter.
The Entire Virial Radius of the Fossil Cluster RXJ1159+5531: I. Gas Properties

description: Previous analysis of the fossil-group/cluster RXJ1159+5531 with X-ray observations from a central Chandra pointing and an offset-North Suzaku pointing indicate a radial intracluster medium (ICM) entropy profile at the virial radius ($R_{\rm vir}$) consistent with predictions from gravity-only cosmological simulations, in contrast to other cool-core clusters. To examine the generality of these results, we present three new Suzaku observations that, in conjunction with the North pointing, provide complete azimuthal coverage out to $R_{\rm vir}$. With two new Chandra ACIS-I observations overlapping the North Suzaku pointing, we have resolved $\gtrsim$50\% of the cosmic X-ray background there. We present radial profiles of the ICM density, temperature, entropy, and pressure obtained for each of the four directions. We measure only modest azimuthal scatter in the ICM properties at $R_{\rm 200}$ between the Suzaku pointings: 7.6\% in temperature and 8.6\% in density, while the systematic errors can be significant. The temperature scatter, in particular, is lower than that studied at $R_{\rm 200}$ for a small number of other clusters observed with Suzaku. These azimuthal measurements verify that RXJ1159+5531 is a regular, highly relaxed system. The well-behaved entropy profiles we have measured for RXJ1159+5531 disfavor the weakening of the accretion shock as an explanation of the entropy flattening found in other cool-core clusters but is consistent with other explanations such as gas clumping, electron-ion non-equilibrium, non-thermal pressure support, and cosmic ray acceleration. Finally, we mention that the large-scale galaxy density distribution of RXJ1159+5531 seems to have little impact on its gas properties near $R_{\rm vir}$.

description: The numerous idealizations that are involved in the exact microscopic statistical description of complex (dusty) plasmas are discussed in detail. The two prevailing approaches in the Klimontovich description of dusty plasmas are reviewed in a pedagogical manner. The continuous phase space approximation is introduced, within which the more rigorous treatment should collapse to the more heuristic treatment. The plasma Klimontovich equations are shown to be identical, but there are marked differences in the dust Klimontovich equations whose origin is analyzed in depth.

Cascading effects of predator richness

Year: 2008

description: Biologists have long known that predators play a key role in structuring ecological communities, but recent research suggests that predator richness - the number of genotypes, species, and functional groups that comprise predator assemblages - can also have cascading effects on communities and ecosystem properties. Changes in predator richness, including the decreases resulting from extinctions and the increases resulting from exotic invasions, can alter the composition, diversity, and population dynamics of lower trophic levels. However, the magnitude and direction of these effects are highly variable and depend on environmental context and natural history, and so are difficult to predict. This is because species at higher trophic levels exhibit many indirect, non-additive, and behavioral interactions. The next steps in predator biodiversity research will be to increase experimental realism and to incorporate current knowledge about the functional role of predator richness into ecosystem management.

description: The major challenge to stewardship of protected areas is to decide where, when, and how to intervene in physical and biological processes, to conserve what we value in these places. To make such decisions, planners and managers must articulate more clearly the purposes of parks, what is valued, and what needs to be sustained. A key aim for conservation today is the maintenance and restoration of biodiversity, but a broader range of values are also likely to be considered important, including ecological integrity, resilience, historical fidelity (ie the ecosystem appears and functions much as it did in the past), and autonomy of nature. Until recently, the concept of "naturalness" was the guiding principle when making conservation-related decisions in park and wilderness ecosystems. However, this concept is multifaceted and often means different things to different people, including notions of historical fidelity and autonomy from human influence. Achieving the goal of nature conservation intended for such areas requires a clear articulation of management objectives, which must be geared to the realities of the rapid environmental changes currently underway. We advocate a pluralistic approach that incorporates a suite of guiding principles, including historical fidelity, autonomy of nature, ecological integrity, and resilience, as well as managing with humility. The relative importance of these guiding principles will vary, depending on management goals and ecological conditions.
title: Battle in the Blood Development of a Mobile Game to Increase Uptake of HIV Services Among Young Key Populations in the Philippines: Mixed Methods Case Study
Creators: name: Hemingway, Charlotte
Publisher: name: University of Liverpool Repository
Year: 2021

description: Background While progress has been made against the UNAIDS 90-90-90 targets, public health gains made in the adult population continue to elude adolescent and young key populations. Progress is not the same in all countries with the Philippines experiencing a sharp rise in HIV infections among young key populations with limited uptake of testing and treatment services. Behaviour change is key to addressing these issues and interventions targeted at this cohort need to be relevant and engaging to successfully compete for their attention, change perceptions, and encourage positive health-related behaviour. The advent and popularity of mobile gaming in the Philippines position digital behaviour change games as a promising platform. Through gameplay, users can traverse a carefully constructed narrative, exposing them to new perspectives around HIV and increasing knowledge of early signs of HIV infection, risk behaviours and available testing and treatment services. While the use of digital games for HIV prevention and detection has rapidly increased in recent times, little is known about game development and effectiveness in low and middle-income (LMIC) contexts. In addition, evidence through randomized control trial design of the effectiveness of games underpinned by cognitive theories of behaviour change is weak, denoting a need to re-think the contribution of these games to the health development field and how we evaluate them. Study Aim To explore the contribution and limitations of a tailored digital game for health aimed at improving HIV-related knowledge, attitudes and practices among young key populations in the Philippines. Objectives 1. To identify appropriate learning objectives and theoretically driven game design relating to HIV prevention and control among young key populations in the Philippines. 2. To develop a playable and acceptable behaviour change game targeted at young key populations in the Philippines. 3. To assess demand and reach of the game among target users. 4. To explore the effect of the game on cognitive and social determinants of HIV service use and behaviour.

description: We study the zero-temperature phase diagram of a one-dimensional array of QED cavities where, besides the single-photon hopping, an additional coupling between neighboring cavities is mediated by an N-type four-level system. By varying the relative strength of the various couplings, the array is shown to exhibit a variety of quantum phases including a polaritonic Mott insulator, a density-wave and a superfluid phase. Our results have been obtained by means of numerical density-matrix renormalization group calculations. The phase diagram was obtained by analyzing the energy gaps for the polaritons, as well as through a study of two-point correlation functions.

title: Trans-editing of Saudi-related News by the British Press: Positioning and Agency
Creators: name: Alsallum, Eithar
Publisher: name: University of Liverpool Repository
Year: 2026

description: Translation is usually perceived as an ‘invisible’ part of journalists’ daily routine at the foreign desks of newspapers. Despite the key socio-political role played by translation in international news production, the contributors behind this complex process have received scant attention from scholars in Translation Studies. The present research explores the role played by institutional and individual agents in positioning Saudi news in the British press through multiple processes of ‘trans-editing’, a term coined in 1989 by Stetting. The study examines three quality British newspapers—The Guardian, The Independent and The Telegraph—to investigate how their social dispositions shaped their trans-editing of Saudi-related news during a period of reform from August 2015 to July 2016. This thesis proposes a combined conceptual framework of Bourdieu’s theory of social practice and analytical tools from an appraisal framework and Pedersen’s ‘Venutian scale’ framework. The thesis investigates contributing agents within each institution (journalists) and outside institutional settings (cited Twitter users), analysing them in terms of their collective and individual forms of habitus, accumulated and exchanged forms of capital and the space to where they function, i.e. field. To support this analysis, the thesis assembled a unique dataset of English-language hard news reports taken from the three broadsheets as well as institutional documents. These were supplemented by original semi-structured interviews with the most prolific journalists. The findings generated by the analysis suggest that the collective forms of newspapers’ habitus dominate the trans-editing process over individual habituses. The authorial power of each individual journalist is associated with their positions within their parent institutions as senior journalists have more space to exhibit distinguishing trans-editing strategies compared to newcomers. The findings also reveal a common tendency towards distancing Saudi Arabia through trans-editing, but the extent to which news is domesticated or foreignised is linked to the accumulated linguistic capital of journalists. Ultimately, this study shows that the invisibility of trans-editing can be observed more in the context of translation from Arabic into English, compared to other language pairs, due to the hegemonic status of English in news reporting, which means that trans-editing from Arabic is not a field on its own, but rather an activity within the British journalistic field and therefore needs to be perceived as a social practice in the broader context of news production.

description: Filaments have been studied in detail through observations and simulations. A range of numerical works have separately investigated how chemistry and diffusion effects, as well as magnetic fields and their structure impact the gas dynamics of the filament. However, non-ideal effects have hardly been explored thus far. We investigate how non-ideal magnetohydrodynamic (MHD) effects, combined with a simplified chemical model affect the evolution and accretion of a star-forming filament. We modeled an accreting self-gravitating turbulent filament using lemongrab, a one-dimensional (1D) non-ideal MHD code that includes chemistry. We explore the influence of non-ideal MHD, the orientation and strength of the magnetic field, and the cosmic ray ionization rate, on the evolution of the filament, with particular focus on the width and accretion rate. We find that the filament width and the accretion rate are determined by the magnetic field properties, including the initial strength, the coupling with the gas controlled by the cosmic ray ionization rate, and the orientation of the magnetic field with respect to the accretion flow direction. Increasing the cosmic-ray ionization rate leads to a behavior closer to that of ideal MHD, reducing the magnetic pressure support and, hence, damping the accretion efficiency with a consequent broadening of the filament width. For the same reason, we obtained a narrower width and a larger accretion rate when we reduced the initial magnetic field strength. Overall, while these factors affect the final results by approximately a factor of~2, removing the non-ideal MHD effects results in a much greater variation (up to a factor of~7). The inclusion of non-ideal MHD effects and the cosmic-ray ionization is crucial for the study of self-gravitating filaments and in determining critical observable quantities, such as the filament width and accretion rate.

SOCP relaxation bounds for the optimal subset selection problem applied to robust linear regression

description: This paper deals with the problem of finding the globally optimal subset of h elements from a larger set of n elements in d space dimensions so as to minimize a quadratic criterion, with an special emphasis on applications to computing the Least Trimmed Squares Estimator (LTSE) for robust regression. The computation of the LTSE is a challenging subset selection problem involving a nonlinear program with continuous and binary variables, linked in a highly nonlinear fashion. The selection of a globally optimal subset using the branch and bound (BB) algorithm is limited to problems in very low dimension, tipically d<5, as the complexity of the problem increases exponentially with d. We introduce a bold pruning strategy in the BB algorithm that results in a significant reduction in computing time, at the price of a negligeable accuracy lost. The novelty of our algorithm is that the bounds at nodes of the BB tree come from pseudo-convexifications derived using a linearization technique with approximate bounds for the nonlinear terms. The approximate bounds are computed solving an auxiliary semidefinite optimization problem. We show through a computational study that our algorithm performs well in a wide set of the most difficult instances of the LTSE problem.

description: As an obligate intracellular parasite, Kaposi sarcoma-associated herpesvirus (KSHV) relies on the host cell machinery to meet its needs for survival, viral replication, production, and dissemination of progeny virions. KSHV is a gammaherpesvirus that is associated with three different malignancies: Kaposi sarcoma (KS), and two B cell lymphoproliferative disorders, primary effusion lymphoma (PEL) and multicentric Castleman’s disease. KSHV viral proteins modulate the cellular phosphatidylinositol-3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) signaling pathway, which is a ubiquitous pathway that also controls B lymphocyte proliferation and development. We review the mechanisms by which KSHV manipulates the PI3K/AKT/mTOR pathway, with a specific focus on B cells.

description: Spectroscopic observations of stars in young open clusters have revealed evidence for a dichotomous distribution of stellar rotational velocities, with 10-30% of stars rotating slowly and the remaining 70-90% rotating fairly rapidly. At the same time, high-precision multiband photometry of young star clusters shows a split main sequence band, which is again interpreted as due to a spin dichotomy. Recent papers suggest that extreme rotation is required to retrieve the photometric split. Our new grids of MESA models and the prevalent SYCLIST models show, however, that initial slow (0-35% of the linear Keplerian rotation velocities) and intermediate (50-65% of the Keplerian rotation velocities) rotation are adequate to explain the photometric split. These values are consistent with the recent spectroscopic measurements of cluster and field stars, and are likely to reflect the birth spin distributions of upper main-sequence stars. A fraction of the initially faster-rotating stars may be able to reach near-critical rotation at the end of their main-sequence evolution and produce Be stars in the turn-off region of young star clusters. However, we find that the presence of Be stars up to two magnitudes below the cluster turnoff advocates for a crucial role of binary interaction in creating Be stars. We argue that surface chemical composition measurements may help distinguish these two Be star formation channels. While only the most rapidly rotating, and therefore nitrogen-enriched, single stars can evolve into Be stars, slow pre-mass-transfer rotation and inefficient accretion allows for mild or no enrichment even in critically rotating accretion-induced Be stars. Our results shed new light on the origin of the spin distribution of young and evolved B-type main sequence stars.

On many benchmark datasets, the MCM generalizes better than SVMs and uses far fewer support vectors than the number used by SVMs. In this paper, we describe a neural network based on a linear dynamical system, that converges to the MCM solution. The proposed MCM dynamical system is conducive to an analogue circuit implementation on a chip or simulation using Ordinary Differential Equation (ODE) solvers. Numerical experiments on benchmark datasets from the UCI repository show that the proposed approach is scalable and accurate, as we obtain improved accuracies and fewer number of support vectors (upto 74.3% reduction) with the MCM dynamical system.

title: Human Rights and British Foreign Policy, c. 1977-1997: An Intellectual Biography of David Owen
Creators: name: Grealy, David

description: In the rapidly expanding historiography on human rights and their growing presence within international relations during the second half of the twentieth century, British foreign policy perspectives remain largely underappreciated. Focussing on David Owen’s sustained engagement with the related concepts of human rights and humanitarianism from his tenure as UK Foreign and Commonwealth Secretary to his influential role in lobbying the New Labour Government of Tony Blair as a member of the Carnegie Commission on Preventing Deadly Conflict, this thesis addresses this striking omission by exploring the relationship between international human rights promotion and British foreign policy between c. 1977-97. Consequently, this thesis contributes to ongoing historiographical debates surrounding the elevation of human rights considerations within foreign policy decision making, examining how Owen’s advocacy reflected broader trends concerning the contested ‘breakthrough’ of human rights during the 1970s and their influence in international relations thereafter. The thesis finds that while there is much to support the notion, well-established within the existing literature, that the 1970s constituted a pivotal moment in the history of human rights, a preoccupation with the identification of such epochal ruptures risks overlooking the ways in which human rights ideas had been shaped by earlier developments and continued to evolve subsequently. Furthermore, in the process of highlighting the fragmented and highly contingent nature of human rights history, this thesis underscores the need to be attentive to the creation of distinctive human rights “vernaculars” that reflected the ideas that historical actors brought to them, and the political purposes they intended to serve by articulating their claims in the language of human rights. By bringing these issues and debates into focus through the lens of Owen’s long-standing commitment to human rights, this thesis also offers a fresh perspective on one of the most recognisable, albeit enigmatic, parliamentarians in recent British history. Both within the confines of Whitehall and without, Owen’s advocacy served to alter the course of British foreign policy at key junctures during the late Cold War and early post-Cold War periods, and provides a unique prism through which to interrogate the intersections between Britain’s enduring search for a distinctive ‘role’ in the world and the development of the international human rights regime during the period in question.

description: Currently, the telehealth monitoring field has gained huge attention due to its noteworthy use in day-to-day life. This advancement has led to an increase in the data collection of electrophysiological signals. Due to this advancement, electrocardiogram (ECG) signal monitoring has become a leading task in the medical field. ECG plays an important role in the medical field by analysing cardiac physiology and abnormalities. However, these signals are affected due to numerous varieties of noises, such as electrode motion, baseline wander and white noise etc., which affects the diagnosis accuracy. Therefore, filtering ECG signals became an important task. Currently, deep learning schemes are widely employed in signal-filtering tasks due to their efficient architecture of feature learning. This work presents a deep learning-based scheme for ECG signal filtering, which is based on the deep autoencoder module. According to this scheme, the data is processed through the encoder and decoder layer to reconstruct by eliminating noises. The proposed deep learning architecture uses a modified ReLU function to improve the learning of attributes because standard ReLU cannot adapt to huge variations. Further, a skip connection is also incorporated in the proposed architecture, which retains the key feature of the encoder layer while mapping these features to the decoder layer. Similarly, an attention model is also included, which performs channel and spatial attention, which generates the robust map by using channel and average pooling operations, resulting in improving the learning performance. The proposed approach is tested on a publicly available MIT-BIH dataset where different types of noise, such as electrode motion, baseline water and motion artifacts, are added to the original signal at varied SNR levels.
title: The Manufacture of Official Roman Silver Coinage and Blanks Between AD193 and AD270

description: This thesis addresses the lack of microstructural data for Roman silver coins which has impeded our understanding of the methods used in their manufacture. In particular, many questions remain about the silvering technologies used to conceal the debased nature of Roman silver minted in the third century AD. Previous investigations into Roman silver coinage have focused on determining episodes of debasement by identifying the fineness and weights of different issues and precise elemental profiles can now be achieved using minimally destructive techniques. Comparatively, few studies have looked at the methods used to manufacture the coins. Destructive microstructural analysis is often necessary to establish the minting technologies employed by ancient moneyers. Since ancient coins are precious objects with both intrinsic and cultural value, they are often subject to strict sampling regulations. The limited access to coins for destructive analysis is the main reason for the shortage of microstructural data for Roman silver coins. For this investigation, a group of 36 Roman silver coins, minted between AD193 and AD270, were investigated using optical microscopy (OM) and scanning electron microscopy (SEM). Complementary elemental data were acquired using energy dispersive spectroscopy (EDS) and mass plasma atomic emission spectroscopy (MP-AES). Experiments were carried out to explore specific aspects of the minting process related to the different potential silvering technologies. The blanks created in the experimental castings provided microstructural data, acquired under controlled conditions, which were then compared to the ancient examples. The study revealed that silver-copper alloy blanks were artificially enriched using repetitive cycles of oxidation and blanching. Inverse segregation of the silver-rich eutectic phase was found to play no role in artificially enriching the surfaces of silver-copper alloy blanks. The investigation found that the surfaces of later quaternary alloy blanks introduced sometime between Valerian and Gallienus joint reign (AD253-260) and Gallienus sole reign (AD260-268), were artificially enhanced by a direct form of enrichment. The exudation of these white-metals creates a white-metal coating. A comparison of the ancient quaternary alloy coins and the experimental blanks revealed many shared microstructural features characteristic of direct enrichment. The evidence put forward in this thesis delivers an answer to this long-standing question. The application of heat to a cast quaternary alloy blank promotes segregation of the silver, tin and lead to the surface.

description: Three alleles of the Drosophila melanogaster vermilion (v) gene are suppressed by recessive mutations at the suppressor of sable [su(s)], gene. Previous work has established that these alleles have identical insertions of the 412 retrotransposon in the 5'-untranslated region of the gene. Despite the transposon insertion in an exon, v mutants accumulate trace amounts of apparently wild-type-sized transcripts in a su(s)+ background, and the level of v transcript accumulation is increased by su(s) mutations. Here, we have characterized transcripts from a suppressible v mutant in both su(s)+ and su(s)- backgrounds by S1 nuclease protection experiments and sequence analysis of polymerase chain reaction (PCR) generated cDNA clones. We find that transposon sequences are imprecisely eliminated from v mutant transcripts by splicing at donor and acceptor sites located near the ends of the 412 retrotransposon. Four different 5' donor sites are alternatively spliced to a single 3' acceptor site. The implications of this finding are discussed in relation to possible functions of the su(s)+ gene product.

description: The STE11 gene of Saccharomyces cerevisiae is one of several genes required for mating between two haploid cell types of this yeast. Its product is required for response to a signal that causes arrest of the mitotic cell cycle in the G1 phase and induction of mating-type-specific genes. The nucleotide sequence of the STE11 gene was determined. The predicted amino acid sequence shows homology to the protein kinase family. We demonstrate that the STE11 product has kinase catalytic activity and that this activity is required for its in vivo functions.

description: We consider $Z'$s in heterotic string derived models and study $Z'$ resonant production at the TeV scale at the Large Hadron Collider (LHC). We use various kinematic differential distributions for the Drell-Yan process at NNLO in QCD to explore the parameter space of such models and investigate $Z'$ couplings. In particular, we study the impact of $Z$-$Z'$ kinetic-mixing interactions on forward-backward asymmetry ($A_{FB}$) and other distributions at the LHC.
