description: In order to explain the observed anomalies in the measurements of $R_{D^{(*)}}$ and $R_{J/ψ}$, a variety of new-physics (NP) models that contribute to $b\to cτ^-{\barν}$ have been proposed. In this paper, we show how CP-violating observables can be used to distinguish these NP models. Because ${\vec p}_τ$ cannot be measured (the decay products of the $τ$ include the undetected $ν_τ$), obtaining the angular distribution of ${\bar B}^0\to D^{*+}τ^{-}{\barν}_τ$ is problematic. Instead, we focus here on ${\bar B}^0\to D^{*+}(\to D^0 π^+)μ^- {\barν}_μ$. This process may also receive contributions from the same NP, and LHCb intends to measure the CP-violating angular asymmetries in this decay. There are two classes of NP models that contribute to $b\to cμ^-{\barν}_μ$. These involve (i) a $W'$ (two types) or (ii) a leptoquark (LQ) (six types). The most popular NP models predict no CP-violating effects, so the measurement of nonzero CP-violating symmetries would rule them out. Furthermore these measurements allow one to distinguish the $W'$ and LQ models, and to differentiate among several LQ models.

description: Suppose G is a real reductive Lie group in Harish-Chandra's class. We propose here a structure for the set Π_u(G) of equivalence classes of irreducible unitary representations of G. (The subscript u will be used throughout to indicate structures related to unitary representations.) We decompose Π_{u}(G) into disjoint subsets with a (very explicit) discrete parameter set Λ_u: Π_u(G) = \bigcup_{λ_u \in Λ_u} Π_u^{λ_u}(G). Each subset is identified conjecturally with a collection of unitary representations of a certain subgroup G(λ_u) of G. (We will give strong evidence and partial results for this conjecture.) In this way the problem of classifying Π_u(G) would be reduced (by induction on the dimension of G) to the case G(λ_u) = G.

description: We report an upper bound on the strain amplitude of gravitational wave bursts in a waveband from around 800Hz to 1.25kHz. In an effective coincident observing period of 62 hours, the prototype laser interferometric gravitational wave detectors of the University of Glasgow and Max Planck Institute for Quantum Optics, have set a limit of 4.9E-16, averaging over wave polarizations and incident directions. This is roughly a factor of 2 worse than the theoretical best limit that the detectors could have set, the excess being due to unmodelled non-Gaussian noise. The experiment has demonstrated the viability of the kind of observations planned for the large-scale interferometers that should be on-line in a few years time.

description: The article seeks to establish the origins of two early-eighteenth-century buildings in the village of Charlton, West Sussex. These are the `Great Room' or `Dome' (the first Fox Hall), which no longer stands, and the Duke of Richmond's hunting-lodge (the second Fox Hall), which survives. The paper is a development on a short article published in Country Life on 17 January 2002, which sought to place the hunting-lodge in context and to attribute it to the architect Roger Morris. The article presented here additionally surveys all known details of the Great Room, or first Fox Hall, an early exercise by the great scholar-patron Richard Boyle, third Earl of Burlington. It also investigates the question of its location. Both buildings are looked at within the context of the early history of hunting, of the patronage of the first two Dukes of Richmond, and of the Palladian movement in architecture. Use is made of the unpublished notes prepared by the late Charlotte Haslam for the Landmark Trust, together with a fresh look at maps in the West Sussex Record Office, some of which have been redated. The article thus draws together previous discussion about the two buildings, combining with new information to give a picture of how the two buildings related to each other.
Noise Optimization for High-Bandwidth Ion Channel Recordings

description: Single-molecule measurements often exhibit weak signals and fast kinetics, making them particularly challenging to record with high fidelity. This thesis presents an analysis of voltage-clamp current recordings of single ion channels, and concludes that considerable improvements in signal-to-noise ratios can be achieved by minimizing all parasitic capacitances associated with these measurements. A custom integrated amplifier in a 0.13-micron complementary metal oxide semiconductor (CMOS) process is designed for high-bandwidth ion channel recordings, and systems are designed to closely incorporate this amplifier with solid-state nanopore sensors, lipid membranes, and biological ion channels. The low capacitance of these integrated platforms reduces noise at high frequencies, enabling signals to be measured up to ten times faster than had been previously achieved. In addition to improving signal quality, the small physical size of these integrated systems portends the arrival of massively parallel high-performance ion channel recording systems for drug discovery and biomolecular sensing applications.

description: Recent experiments with strongly interacting, driven Rydberg ensembles have introduced a promising setup for the study of self-organized criticality (SOC) in cold atom systems. Based on this setup, we theoretically propose a control mechanism for the paradigmatic avalanche dynamics of SOC in terms of a time-dependent drive amplitude. This gives access to a variety of avalanche dominated, self-organization scenarios, prominently including self-organized criticality, as well as sub- and supercritical dynamics. We analyze the dependence of the dynamics on external scales and spatial dimensionality. It demonstrates the potential of driven Rydberg systems as a playground for the exploration of an extended SOC phenomenology and their relation to other common scenarios of SOC, such as e.g. in neural networks and on graphs.

description: It is shown that there exists an on-shell light cone gauge where half of the fermionic components of the super vector potential vanish, so that part of the superspace flatness conditions becomes linear. After reduction to $(1+1)$ space-time dimensions, the general solution of this subset of equations is derived. The remaining non-linear equations are written in a form which is analogous to Yang equations, albeit with superderivatives involving sixteen fermionic coordinates. It is shown that this non-linear part may, nevertheless, be solved by methods similar to powerful technics previously developed for the (purely bosonic) self-dual Yang Mills equations in four dimensions.

Noise Robust Pitch Tracking by Subband Autocorrelation Classification

description: Speech pitch tracking is one of the elementary tasks of the Computational Auditory Scene Analysis (CASA). While a human can easily listen to the voiced pitch in highly noisy recordings, the performance of automatic speech pitch tracking degrades in unknown noisy audio conditions. Traditional pitch trackers use either autocorrelation or the Fourier transform to calculate periodicity, which works well for clean recordings. For noisy recordings, however, the accuracy of these pitch trackers degrades in general. For example, the information in parts of the frequency spectrum may be lost due to analog radio band transmission and/or contain additive noise of various kinds. Instead of explicitly using the most obvious features of autocorrelation, we propose a trained classier-based approach, which we call Subband Autocorrelation Classification (SAcC). A multi-layer perceptron (MLP) classier is trained on the principal components of the autocorrelations of subbands from an auditory filterbank. The output of the MLP classifier is temporally smoothed to produce the pitch track by finding the Viterbi path of a Hidden Markov Model (HMM). Training on various types of noisy speech recordings leads to a great increase in performance over state-of-the-art algorithms, according to both the traditional Gross Pitch Error (GPE) measure, and a proposed novel Pitch Tracking Error (PTE) which more fully reflects the accuracy of both pitch estimation/extraction and voicing detection in a single measure. To verify the generalization and specificity of SAcC, we test SAcC on a real world problem that has a large-scale noisy speech corpus. The data is from the DARPA Robust Automatic Transcription of Speech (RATS) program. The experiments on the performance evaluation of SAcC pitch tracking confirm the generalization power of SAcC across various unknown noise conditions and distinct speech corpora. We also report the use of SAcC output adds a significant improvement to a Speaker Identification (SID) system for RATS as well, suggesting the potential contribution of SAcC pitch tracking in the higher-level tasks.
Noise, sound and objecthood: the politics of representation in avant-garde music

description: This essay offers both a historical analysis of twentieth century avant-garde practices relating to representation in music, and a prescriptive model for contemporary methods of composition. I address the taxonomy problem in classical music, clarifying the ontological divide identified by German musicologist Michael Rebhahn Contemporary Classical music and New Music.
      I demonstrate how neoliberalism has developed a Global Style (Foster 2012) of "Light Modernity,” evident in both contemporary architecture and music alike. The central problem facing composition today is the fetishization of materials, ultimately derived from music's refusal to allow the question of representation to be addressed.
      I argue that composers have largely sought to define noise as sound-in-itself, eliminating the possibilities of representation in the process. Proposing instead that composers should strive to tackle representation head-on in the 21st century, I show how Jacques Rancière provides a model in which noise and sound—representation and abstraction—function in a conjoined, yet non-homogenized aesthetic regime. Governed by what he calls the "pensiveness of the image,” it allows for a renewed art form that rejects repetition and neoliberalism, re-connecting to the spirit of the avant-garde without slavishly echoing either its outmoded aesthetics or dogmatic philosophies.

description: Steering of magnetic nano-/microhelices by a rotating magnetic field is considered as a promising technique for controlled navigation of tiny objects through viscous fluidic environments. It has been recently demonstrated that simple geometrically achiral planar structures can also be steered efficiently. Such planar propellers are interesting for practical reasons, as they can be mass-fabricated using standard micro/nanolithography techniques. While planar magnetic structures are prone to in-plane magnetization, under the effect of an in-plane rotating magnetic field, they exhibit, at most, propulsion due to spontaneous symmetry breaking, i.e., they can propel either parallel or anti-parallel to the rotation axis of the field depending on their initial orientation. Here we demonstrate that actuation by a conically rotating magnetic field (i.e., superposition of in-plane rotating field and constant field orthogonal to it) can yield efficient unidirectional propulsion of planar and magnetized in-plane structures. In particular, we found that a highly symmetrical V-shape magnetized along its symmetry axis which exhibits no net propulsion in in-plane rotating field, exhibits unidirectional in-sync propulsion with a constant (frequency-independent) velocity when actuated by the conically rotating field.

Non-Bayesian Inference and Prediction

description: In this thesis, we first propose a coherent inference model that is obtained by distorting the prior density in Bayes' rule and replacing the likelihood with a so-called pseudo-likelihood. This model includes the existing non-Bayesian inference models as special cases and implies new models of base-rate neglect and conservatism. We prove a sufficient and necessary condition under which the coherent inference model is processing consistent, i.e., implies the same posterior density however the samples are grouped and processed retrospectively. We show that processing consistency does not imply Bayes' rule by proving a sufficient and necessary condition under which the coherent inference model can be obtained by applying Bayes' rule to a false stochastic model. We then propose a prediction model that combines a stochastic model with certain parameters and a processing-consistent, coherent inference model. We show that this prediction model is processing consistent, which states that the prediction of samples does not depend on how they are grouped and processed prospectively, if and only if this model is Bayesian. Finally, we apply the new model of conservatism to a car selection problem, a consumption-based asset pricing model, and a regime-switching asset pricing model.
Selenium monitoring and management : new mines
Creators: name: Chapman, Peter M.
Publisher: name: The University of British Columbia
Year: 2009

description: Selenium is a contaminant of particular concern for coal, phosphate, uranium and some precious and base metal mines. Regulators require reasonable assurances that environmental risks will be detected and ameliorated. Proponents require reasonable assurances regarding potential future liabilities. Provision of such assurances requires: identification of receptors of potential concern (for monitoring and investigative studies); generic and specific guiding principles; a three-tiered strategy (potential risk of impact? → realistic risk of impact? → any necessary management actions?); and, adaptive management. Primary levels of protection should be based on both appropriate whole body tissue (not water) guidelines (the present BC interim tissue guideline value does not appear to be appropriate), and background data (which can be naturally elevated). Background data should be used, where appropriate, as site-specific initial guidelines within the tiered strategy.

description: The ubiquitin-proteasome system is essential to all eukaryotes and has been shown to be critical to parasite survival as well, including Plasmodium falciparum, the causative agent of the deadliest form of malarial disease. Despite the central role of the ubiquitin-proteasome pathway to parasite viability across its entire life-cycle, specific inhibitors targeting the individual enzymes mediating ubiquitin attachment and removal do not currently exist. The ability to disrupt P. falciparum growth at multiple developmental stages is particularly attractive as this could potentially prevent both disease pathology, caused by asexually dividing parasites, as well as transmission which is mediated by sexually differentiated parasites. The deubiquitinating enzyme PfUCHL3 is an essential protein, transcribed across both human and mosquito developmental stages. PfUCHL3 is considered hard to drug by conventional methods given the high level of homology of its active site to human UCHL3 as well as to other UCH domain enzymes. Here, we apply the RaPID mRNA display technology and identify constrained peptides capable of binding to PfUCHL3 with nanomolar affinities. The two lead peptides were found to selectively inhibit the deubiquitinase activity of PfUCHL3 versus HsUCHL3. NMR spectroscopy revealed that the peptides do not act by binding to the active site but instead block binding of the ubiquitin substrate. We demonstrate that this approach can be used to target essential protein-protein interactions within the Plasmodium ubiquitin pathway, enabling the application of chemically constrained peptides as a novel class of antimalarial therapeutics.

description: We study unimodular gravity in the context of cosmology, particularly some interesting consequences that might be able to describe the background cosmology and the late cosmic acceleration. We focus our attention on the hypothesis of \textit{non conservation of the energy momentum tensor}. This characteristic has an interesting outcome: we can obtain a modified Friedmann equation along with the acceleration equation and also new fluid equations related to a third order derivative of the scale factor, known in cosmography as the jerk parameter. As a consequence of this theory, it seems that radiation and the cosmological constant are intimately related, in agreement with what some authors have called the third coincidence problem. Their connection is the parameter $z_{ini}$, which has a value of $11.29$ and coincide with the reionization epoch. As a result, we are able to explain the late acceleration as a natural consequence of the equations, associating the new fluid to radiation and, thus, eliminating the need for another component (i.e. dark energy). Finally, we interpret the results and discuss the pros and cons of using the cosmological constant under the hypothesis of non conservation of the energy momentum tensor in the unimodular gravity scenario.

description: The study analyzed the socioeconomic determinants influencing the willingness of the agriculture undergraduates to participate in agripreneurship in Northwest, Nigeria. The study employed a questionnaire to obtain primary data. A multistage sampling technique was used to select 150 respondents from the universities under study. Both descriptive and inferential statistics were used for data analysis. Results show that a majority of the participants were male (68.7%), single (90%), within 21-25 years of age (52.6%), and had no any other tangible occupation (57.3%) besides study. Willingness to participate in agripreneurship was found to be positive among the respondents but not as primary occupation. Family economic status (ranked first) was the major socioeconomic determinants influencing the willingness of agriculture undergraduates to participate in agripreneurship. Examination of the relationship between selected socioeconomic determinants and willingness to participate in agripreneurship revealed a positive significant relationship with gender, community background, family background, family economic status, as well as with ethnicity. This clearly suggests that a number of socioeconomic determinants have considerable influence over willingness of agriculture undergraduates to participate in agripreneurship. The study, then, carries the implication that university agriculture training should be streamlined with today’s realities so as to stimulate the willingness for agripreneurship.

Results from X-ray structure analysis at different temperatures revealed in the case of 1 that the transition from a gradual to a cooperative SCO with a 5 K wide hysteresis is due to an increase of the short intermolecular contacts, which exceed a certain threshold for the cooperative effect. In the case of compound 2 an incomplete spin transition with a 4 K wide hysteresis was observed. The low temperature [small chi]MT product remains constant at a value typical for a mixed HS/LS state in stepwise spin transitions. A quantitative correlation between the cooperative effects of 12 monomer and polymer iron(ii) SCO complexes and their structural properties derived from X-ray structure analysis, the so-called crystal contact index, CCI, is introduced.

Chaotic eigenstates give rise to an equilibrium occupation number distribution in close agreement with the Bose-Einstein distribution despite the small number of particles ($n=2$). However, the corresponding temperature differs from that derived from the standard Canonical Ensemble. On the other side, an acceptable agreement with the latter is restored by artificially randomizing the model. Different definitions of temperature are then discussed and compared .

description: What role does ethical theory play in everyday deliberation? On the ideal view, agents are taken to have an overriding commitment to a theory that dictates the obligatory, permissible, and forbidden actions in every conceivable situation. I argue that the ideal view imposes undesirable psychological burdens, whereas a non-ideal view—on which agents act according to the norms of their local practices and appeal to theory only when those norms prove insufficient to resolve particular problems—does not. Inspired by J. S. Mill, I develop one non-ideal theory for practices of regret, toleration, punishment, and partiality.

description: In this paper we study hermitian kernels invariant under the action of a semigroup with involution. We characterize those hermitian kernels which realize the given action by bounded operators on a Krein space. Applications to the GNS representation of *-algebras associated to hermitian functionals are given. We explain the key role played by the Kolmogorov decomposition in the construction of Weyl exponentials associated to an indefinite inner product and in the dilation thoery of hermitian maps on C*-algebras.

 DOMINICAN REPUBLIC: Independencia Province, Duvergé, Vila Barrancoli; 7 July 2018, 1521 PDT; B. A. Roy. Host: Heteropoda venatoria Linnaeus (Sparassidae), juvenile [det. A. Tosto and R. C. West]. The wasp is grasping the immobilized huntsman spider midway on its right pedipalp with her mandibles, while pulling it backwards, dorsal side upward, vertically up a debarked upright post with a natural cavity part way up. Two other photographs show the spider positioned inside of the cavity, apart from the wasp. It is unknown whether the wasp placed the spider in the cavity in order to rest, after the strenuous prey transport, or whether she put it there in order to lay an egg on its abdomen and conceal it with debris (Roy 2021).

description: The Unemployed Workmen Act 1905 was the turning point in dealing with the unemployed. it marked the transition from a system based on charity and local relief works to one in which the state accepted responsibility for tackling unemployment as a national issue. The Act was a failure and did little for the unemployed, but Brighton used it to better effect than any other town. This is an account of how the Act was implemented in Brighton, and of how a group of councillors campaigned against the Act while at the same time using it on behalf of the men they represented.

description: We present exact calculations of the zero-temperature partition function $Z(G,q,T=0)$ and ground-state degeneracy $W(\{G\},q)$ for the $q$-state Potts antiferromagnet on a number of families of graphs $G$ for which (generalizing $q$ from ${\mathbb Z}_+$ to ${\mathbb C}$) the boundary ${\cal B}$ of regions of analyticity of $W$ in the complex $q$ plane is noncompact, passing through $z=1/q=0$. For these types of graphs, since the reduced function $W_{red.}=q^{-1}W$ is nonanalytic at $z=0$, there is no large--$q$ Taylor series expansion of $W_{red.}$. The study of these graphs thus gives insight into the conditions for the validity of the large--$q$ expansions. It is shown how such (families of) graphs can be generated from known families by homeomorphic expansion.

Interrogating Cuban Womanhood in Norge Espinosa Mendoza’s La virgencita de bronce
Creators: name: Ford, Katherine
Publisher: name: Skenè. Journal of Theatre and Drama Studies

description: La virgencita de bronce (2004), from Cuban playwright Norge Espinosa Mendoza uses actors and puppets to dramatize the classic novel Cecilia Valdés, in the process questioning the classic Cuban myth and definitions of Cuban womanhood. Cecilia Valdés is a pivotal figure in Cuban culture, since the days that Cirilo Villaverde first wrote the novel (1839) and Norge Espinosa Mendoza’s La virgencita de bronce, written at the request of the important Teatro de las Estaciones in the small city of Matanzas, gives the Cuban stage the opportunity to interrogate the national canon developed around Cecilia Valdés in an innovative way.

description: Electrostatic correlations play an important role in physics, chemistry and biology. In plasmas they lead to thermodynamic instability similar to the liquid-gas phase transition of simple molecular fluids. For charged colloidal suspensions the electrostatic correlations are responsible for screening and colloidal charge renormalization. In aqueous solutions containing multivalent counterions they can lead to charge inversion and flocculation. In biological systems the correlations account for the organization of cytoskeleton and the compaction of genetic material. In spite of their ubiquity, the true importance of electrostatic correlations has become fully appreciated only quite recently. In this paper, I will review the thermodynamic consequences of electrostatic correlations in a variety of systems ranging from classical plasmas to molecular biology.

Laughing Bodies, Bodies in Pain: How Humour Approaches Torture in Two Works by Eduardo Rovner

description: Torture is a uniquely difficult experience to represent accurately. Nevertheless, we continually struggle to understand, deal with, and preserve the memory of torture. It is paramount to our human societies that the voices of those who were tortured are heard. The transmission of affect in theatre pieces that deal with torture deserves closer attention, in particular in order to understand how dark humour can communicate trauma and torture. Ultimately, laughter and torture are both bound up in the languages of the body and implicate the physical as well as the psychological. As J.M. Bernstein notes, extreme pain and other limit conditions, like laughter, imply our recognition of the instinctual, out of control body. In the theatre, we experience these affective transmissions as a temporary community, which allows for an inquiry into the role of the group, or those who witness torture as an ephemeral community and who also take part in laughter together. Both Concierto de aniversario [Birthday Concert] (1983) and ¿Una foto…? [A Photo?] (1977) by Eduardo Rovner expose and explore this intersection between the laughing body and the tortured body. These works, which deal with both physical torture and psychological manipulation of Argentine citizens during the military dictatorship (1976-83), employ strong applications of the grotesque and absurd which rely on humour. The Argentine tradition of the grotesco criollo places enjoyment and displeasure in direct contact, a process which creates emotional knowledge. This article aims at establishing the value of emotional knowledge when recording the event and aftermath of torture.

description: India has emerged as a key player with a high potential to develop a biomass and biobased economy due to its large geographic size and the massive amounts of agricultural and non agricultural biomass produced. India has joined hands with Europe to synchronize its efforts to create and facilitate the development of a biobased economy in this country. This paper aims to examine common research and development actions between the European Union (EU) and India to facilitate the development of these biobased economies. As a base, a thorough study has been performed considering the biomass potential and current status of the bioeconomy in both the EU and India based on the distillation of a series of 80 potential recommendations. The recommendations were grouped into four major categories: (1) biomass production, (2) by-products/waste, (3) biorefineries and (4) policy, market, and value-added products. A questionnaire was designed and distributed to key stakeholders belonging to: academia, industry, and policymakers in both India and the EU. A total of 231 responses were received and analyzed, based on the key recommendations made for the essential research and development topics that are of prime importance to develop biobased economies in both the EU and India. The findings of this study suggest recognizing the value-added contributions made by biobased products such as: food, feed, valuable materials and chemicals in both regions. It is important to reduce the overall process costs and minimize the environmental impacts of such a biobased economy.

description: Mass drug administration (MDA) is the main counter-transmission strategy of the Global Programme to Eliminate Lymphatic Filariasis. In endemic countries, there are areas where MDA is not required. However, there is no standard approach in these areas, and studies are important to evaluate the epidemiological status. This study aimed to investigate lymphatic filariasis and strategies developed for its control in an area where MDA is not required. Together with the 2018 morbidity evaluation, a survey was conducted using point-of-care immunochromatographic test-AD12 tests for diagnostic screening in an area where MDA is not required. The methodology also included desk research based on Health Department reports of the control activities for lymphatic filariasis during 2003–2016. Among the 934 cases investigated in 2018, there was a 0.64% prevalence of circulating filarial antigen positive, comprising five adults and one 2-year-old child. Six patients aged 39–63 years had filarial disease. Fourteen surveys have already been conducted as control activities, and since 2009, there have been no positive cases. This study showed that the prevalence of antigenemia decreased from 2.97% in 2003 to 0.64% in 2018. Moreover, the transmission of filariasis infection was under control in this area. Our study provides insights into the surveillance phase by identifying areas of low transmission and where MDA is not required. Although we have not identified cases of filarial infection, there is a need to provide services that will provide assist those already affected with morbidity and help reduce and prevent disability.
