description: (63)Cu-NMR measurements have been performed on two-leg hole-doped spin ladders Sr_{14-x}Ca_{x}Cu_{24}O_{41} single crystals (0-x-12) at several pressures up to the pressure domain where the stabilization of a superconducting ground state can be achieved. The data reveal marked decrease of the spin gap derived from Knight shift measurements upon Ca substitution and also under pressure and confirm the onset of low lying spin excitations around P_{c} as previously reported. The spin gap in Sr_{2}Ca_{12}Cu_{24}O_{41} is strongly reduced above 20 kbar. However, the data of an experiment performed at P=36 kbar where superconductivity has been detected at 6.7K by an inductive technique have shown that a significant amount of spin excitations remains gapped at 80K when superconductivity sets in. The standard relaxation model with two and three-magnon modes explains fairly well the activated relaxation data in the intermediate temperature regime corresponding to gapped spin excitations using the spin gap data derived from Knight shift experiments.The data of Gaussian relaxation rates of heavily doped samples support the limitation of the coherence lenght at low temperature by the average distance between doped holes. We discuss the interplay between superconductivity and the spin gap and suggest that these new results support the exciting prospect of superconductivity induced by the interladder tunnelling of preformed pairs as long as the pressure remains lower than the pressure corresponding to the maximum of the superconducting critical temperature.

description: Many methods for modeling functions over high-dimensional spaces assume global smoothness properties; such assumptions are often violated in practice. We introduce a method for modeling functions that display heterogeneity or contain discontinuities. The heterogeneity is dealt with by using a combination of Voronoi tessellation, to partition the input space, and separate Gaussian processes to model the function over different regions of the partitioned space. The proposed method is highly flexible since it allows the Voronoi cells to combine to form regions, which enables nonconvex and disconnected regions to be considered. In such problems, identifying the borders between regions is often of great importance and we propose an adaptive sampling method to gain extra information along such borders. The method is illustrated by simulated examples and an application to real data, in which we see improvements in prediction error over the commonly used stationary Gaussian process and other nonstationary variations. In our application, a computationally expensive computer model that simulates the formation of clouds is investigated, the proposed method more accurately predicts the underlying process at unobserved locations than existing emulation methods.

A Visible History: A Synthesis of Past, Present and Future Through the Evocation of Memory Within Historic Contexts

description: How can new spaces evoke the layers of memory associated with historic places and utilize them to envision anew? What are the spatial strategies involved with creating architecture rich in memory and how can a space which is cognizant of its physical and historical context serve as a tool for revitalization?
These questions could be used to investigate revitalization efforts in much of the cities and towns which line the Connecticut River Valley. Ultimately, solutions become directly rooted in the context to which they are set.
With the industrial village of Turners Falls as the setting, this thesis is based on an evaluation of the village’s contemporary and historic physical and social fabric. Through gaining an understanding of the nuanced history and memories associated with the village, a new cultural center is proposed and meant to serve as a beacon for the village’s budding arts community.
The design approach uses strategies of spatial complexity, tension and ambiguity to draw connections between the past and present in an effort to create a new space which is cognizant of its contemporary and historic context. A sensitivity to siting, tectonics and materiality serve to inform design decisions. Ultimately, the new space reconnects the town back to its history of making by creating a space for renewed innovation in the arts and its siting crafts a future rooted in a harmonious relationship between the village and its waterfront along the Connecticut River.

description: An accurate modelling of baryonic feedback effects is required to exploit the full potential of future weak-lensing surveys such as Euclid or LSST. In this second paper in a series of two, we combine Euclid-like mock data of the cosmic shear power spectrum with an eROSITA X-ray mock of the cluster gas fraction to run a combined likelihood analysis including both cosmological and baryonic parameters. Following the first paper of this series, the baryonic effects (based on the baryonic correction model of Schneider et al. 2019) are included in both the tomographic power spectrum and the covariance matrix. However, this time we assume the more realistic case of a $Λ$CDM cosmology with massive neutrinos, and we consider several extensions of the currently favoured cosmological model. For the standard $Λ$CDM case, we show that including X-ray data reduces the uncertainties on the sum of the neutrino mass by $\sim30$ percent, while there is only a mild improvement on other parameters such as $Ω_m$ and $σ_8$. As extensions of $Λ$CDM, we consider the cases of a dynamical dark energy model (wCDM), a $f(R)$ gravity model (fRCDM), and a mixed dark matter model ($Λ$MDM) with both a cold and a warm/hot dark matter component. We find that combining weak lensing with X-ray data only leads to a mild improvement of the constraints on the additional parameters of wCDM, while the improvement is more substantial for both fRCDM and $Λ$MDM. Ignoring baryonic effects in the analysis pipeline leads to significant false-detections of either phantom dark energy or a light subdominant dark matter component. Overall we conclude that for all cosmologies considered, a general parametrisation of baryonic effects is both necessary and sufficient to obtain tight constraints on cosmological parameters.

description: We have investigated moduli stabilization leading to hierarchical supersymmetry breakdown in racetrack models with two moduli fields simultaneously present in the effective racetrack superpotential. We have shown that stabilization of moduli occurs when a shift symmetry of the moduli space becomes gauged. This gauging results in a D-term contribution to the scalar potential that depends on moduli scalars. To break supersymmetry at a minimum created this way in the case where only a single combination of moduli is present in the superpotential one needs supergravity corrections. If the superpotential depends on two independent combinations of moduli, supersymmetry is broken by non-vanishing F-terms without supergravity terms. Some of the minima that we see correspond to a non-vanishing expectation value of the blowing-up modulus in the case of type IIB orientifold models. We point out that the mass of the gauge boson associated with gauged shift symmetry becomes naturally light in warped compactifications.

description: Purpose: To describe an arcuate retinopathy appearance in a familial cone-rod dystrophy and the underlying genetic cause. Methods: Retrospective case series of an affected three-generation family (eight affected members, eight unaffected members) Results: The proband, a 47-year-old male, noted significant visual loss since his early thirties. In addition to central macular atrophic changes, retinal examination was notable for peripapillary atrophy and an arcuate of drusenoid deep yellow lesions in the temporal macula. Spectral-domain optical coherence tomography in the area of the lesions showed regional outer neurosensory retina loss with nasal extension (forming a ring around the central retina) but no drusen. Full-field electroretinography revealed cone-rod dysfunction with an electronegative waveform. Fifteen other available family members were examined, and seven (age range 13–71 years old) showed variable expressivity for similar phenotypic findings, most notably the arcuate lesions in all but the oldest individual who had end-stage atrophy. Exome sequencing of the proband’s affected daughter uncovered a heterozygous CRX deletion [NM_000554.4: CRX: c.(100 + 1_101-1)_(c.900 + 1_?)del] that segregated with the disease. Conclusion: An unusual familial cone-rod dystrophy phenotype was associated with heterozygous CRX deletion, a pathogenic variant that had a presumed mechanism of haploinsufficiency. The consistent finding of arcuate temporal macular lesions among affected family members was striking, particularly given the variable expressivity previously associated with CRX-related retinopathy. Additional phenotypic studies are needed to assess how frequently this temporal arcuate retinopathy appearance occurs in individuals harboring a similar deletion who are not from the current family.
VIRTUALIZATION OF CLOSED-LOOP SENSOR NETWORKS

Publisher: name: University of Massachusetts Amherst
Year: 2017

description: The existing closed-loop sensor networks are based on architectures that are designed and implemented for one specific application and require dedicated sensing and computational resources. This prevents the sharing of these networks. In this work, we propose an architecture of virtualization to allow sharing of closed-loop sensor networks. We also propose a scheduling approach that will manage requests from competing applications and evaluate their impact on system utilization against utilization achieved by more traditional, dedicated sensor networks. These algorithms are evaluated through trace-driven simulations, where the trace data is taken from CASA’s closed-loop weather radar sensor network. Results from this evaluation show that the proposed scheduling algorithms applied in a shared network result in cost savings, that are the result of being able to multiplex applications onto a single network as opposed to running each application on an dedicated sensor network.

description: Salt River Project (SRP) proposes to construct a railroad transportation corridor from the proposed Fence Lake Coal Mine in Catron County, New Mexico, to the Coronado Generating Station in Apache County, Arizona. The original route of the Arizona corridor was surveyed by O’Brien and Dosh (1987). The New Mexico portion of the corridor and two reroutes along the New Mexico segment were inventoried in 1991 (Morris 1992). A third reroute, also on the New Mexico corridor, was inventoried in 1994 (Gilpin and Anduze 1994). Traditional cultural properties were addressed for the entire Fence Lake project area in Hart and Ferguson (1993). The inventory reported herein was for a fourth proposed reroute, a corridor 1.1 miles (5808 feet) long and 200 feet wide. The direct impact zone is 150 feet wide with a 50-foot-wide buffer zone on the north side. A fence line marks the corridor's southern boundary. The U.S. Department of the Interior (USDI), Office of Surface Mining, is the overall lead agency for the Fence Lake Coal Mine Project and the USDI, Bureau of Land Management, Las Cruces District, Socorro Resource Area, is the lead agency for cultural resources.
Inclusive Nucleon Decay Searches as a Frontier of Baryon Number Violation

description: Proton decay, and the decay of nucleons in general, constitutes one of the most sensitive probes of high-scale physics beyond the Standard Model. Most of the existing nucleon decay searches have focused primarily on two-body decay channels, motivated by Grand Unified Theories and supersymmetry. However, many higher-dimensional operators violating baryon number by one unit, $ΔB = 1$, induce multi-body nucleon decay channels, which have been only weakly constrained thus far. While direct searches for all such possible channels are desirable, they are highly impractical. In light of this, we argue that inclusive nucleon decay searches, $N \rightarrow X +$anything (where $X$ is a light Standard Model particle with an unknown energy distribution), are particularly valuable, as are model-independent and invisible nucleon decay searches such as $n \rightarrow$ invisible. We comment on complementarity and opportunities for such searches in the current as well as upcoming large-scale experiments Super-Kamiokande, Hyper-Kamiokande, JUNO, and DUNE. Similar arguments apply to $ΔB >1$ processes, which kinematically allow for even more involved final states and are essentially unexplored experimentally.

description: Beginning in the early 1980s, the government of Egypt embarked on an aggressive initiative to progressively change its centrally planned economy to a system more dependent on domestic and international markets. The agriculture and food sectors have taken the lead in the economic reforms. This paper investigates changes in Egyptian cropping patterns as an indicator of the 'success' of the transition toward a more market-oriented economy. First, trends in cultivated area and gross margins during the economic reforms are described. Responses of cropping patterns to changes in gross margins are then evaluated. A random effect distributed lag model with pooled cross-sectional time-series methods is used to examine the relationship for individual crops. Canonical correlation analysis provides a more general assessment of responsiveness of the overall cropping pattern.

description: We examine the formation and critical dynamics of topological defects via Kibble-Zurek mechanism in a (2+1)-dimensional quantum critical point, which is conjectured to dual to a Lifshitz geometry. Quantized magnetic fluxoids are spontaneously generated and trapped in the cores of order parameter vortices, which is a feature of type II superconductors. Time evolution of the average condensate is found to lag behind the instantaneous equilibrium value of the order parameter, a typical phenomenon in nonequilibrium dynamics. Scalings of vortex number density and the "freeze-out" time match the predictions from Kibble-Zurek mechanism. From these scalings, the dynamic and static critical exponents in the boundary field theory are found, at least at finite temperature, to be irrespective of the Lifshitz exponent in the bulk.

description: This paper uses duality theory to develop a model of European Community agriculture. The model is used to investigate the impact of the land set-aside provision of the recent package of reforms of the Common Agricultural Policy. We assume that producers chose output and variable input levels that maximize difference between revenue and variable cost. By including first-order conditions for the allocation of land across its uses, we impose that the observed allocations are profit-maximizing allocations. To overcome the problem of incorporating many outputs into an estimable production structure, we imposed a priori the restriction that the technology was weakly separable in major categories of outputs. With this restriction, it was possible to model production decisions in stages using consistent aggregates in the latter stages.

Demand and Price Analysis

description: The paper considers an industry transforming primary commodities (farm products) into processed commodities (food products). It focuses on the allocation of embedded characteristics (carbohydrate, protein, etc.) both across space and among commodities. The approach generates a spatial competitive market equilibrium of production, consumption, transformation, and trade for both primary and processed commodities, along with the spatial distribution of shadow prices for the product characteristics. The model provides a basis for analyzing the allocation and pricing of agricultural products, food products, and characteristics in spatial markets. The empirical usefulness of the model is illustrated in the context of regional resource allocation in the U.S. dairy sector.
Distinct Mechanisms Underlie Attraction Errors and Agreement with Coordination
Creators: name: Keung, Lap-Ching
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Previous research has suggested that attraction errors are not due to the proximity of the local noun and verb, as a more distant local noun can result in more errors than a nearer one (e.g., *The helicopter for the flights over the canyon are vs. *The helicopter for the flight over the canyons are; Franck, Vigliocco, & Nicol, 2002). However, the verb tends to agree in number with the nearer noun of a disjoined subject, suggesting that linear order can indeed play a role in agreement computation (e.g., The horse or the clocks are vs. The horses or the clock is; Haskell & MacDonald, 2005). In the present study, two experiments using a two-alternative forced-choice production paradigm and one experiment using eyetracking during reading directly compared agreement computation in the classic attraction configuration and when the subject is a coordinate phrase. The 2AFC experiments replicated both the lack of a linear distance effect in classic attraction and the presence of a linear order effect in disjunction agreement, which was also extended to conjunction agreement; when the second conjunct was singular, subjects frequently selected a singular verb. This order effect was also modulated by the presence or absence of additional material between the subject and verb. In the eyetracking experiment, a singular second conjunct both facilitated processing of a singular verb and inhibited processing of a plural verb. These results suggest that variable agreement with coordinate subjects is not a form of agreement attraction and that distinct theoretical treatments are required for two distinct phenomena.

title: 'In a lonely street' : 1940's Hollywood, film noir and the 'tough' thriller.
Creators: name: Krutnik, Frank S
Publisher: name: University of Kent
Year: 2022

description: This thesis is concerned with the debates and the problems bound within the concept of 'film noir', one of the most persistently 'mythologised' areas of Hollywood cinema. As I shall show 1 'film noir' was a tern generated within film criticism in order to identify and to account for a complex series of transformations within the Hollywood cinema of the 1940's, particularly around the area of the crime thriller. As I shall suggest, because it functioned as a blanket categorisation, the term has suffered from a mystification which has problematised many of the attempts to come to terms with the historical processes it initially described a problem only exacerbated by its extension to films produced since the early l9O's). This thesis will seek here to re-locate the phenomenon described by the term 'film noir' within Its cinematic and historical contexts. After a general introduction to the debates surrounding 'classical' Hollywood cinema, the genre system of production and the problems represented by the 'film noir', Section Two comprises an examination of the complex determination of the 'noir. phenomenon', suggesting how this resulted from a confluence of intermeshing 'aesthetic', social-cultural, institutional and industrial transformt1ons, Following this explication of the diversity of the determination of film noir, Section Three proposes that a large proportion of the crime thrillers so termed - j . the 'tough' thriller, a cinematic development of the recent 'hard-boiled' trend in American crime fiction - manifests a particularly obsessional representation of problems besetting masculine psychic and sexual identity, and masculine cultural/social authority. Working through the narrative logic of both some of the more famous and some of the more obscure of the 1940's 'film noir' thrillers - such films as 'THE STRANGER ON THE THIRD FLOOR, AMONG THE LIVING, THE MALTESE FALCON, THE WOMAN LN THE WINDOW, WHEN STRANGERS 1ARRY, DOUBLE INDE'UTITY, BLACK ANGEL, MILDRED PIERCE, DETOUR, THE KILLERS, THE BLUE DAHLIA, DEAD RECKONING, OUT OF THE PAST, LADY FROT SHANGHAI, and PITFALL - I will suggest that, despite the confusion which has accreted to the term in the past forty-five years, film noir can prove a valuable means of exploring both (a) the relationships between films and the multiple contexts for which and in which they are produced; and (b) the problems which beset any project of 'masculine consolidation' (with the 'tough' thrillers representing an extreme and much problematised form of hero-centred fiction). By bringing together debates on film history, industry, 'ideology', genre, and gender, it is hoped that this study may offer some suggestions for a much-- needed reorientation of this vital but perplexing 'genre'/period.

description: We report the detection of broad, high-velocity oxygen emission lines from the site of SN 1941C nearly eight decades after outburst, making it the oldest optically detected core-collapse supernova/youngest core-collapse supernova remnant with a well determined age. In contrast to the strongly blueshifted emission line profiles observed for all other late-time CCSNe thought to be due to dust extinction of rear hemisphere ejecta, SN 1941C's spectrum exhibits stronger redshifted than blueshifted emissions of [O I] 6300, 6364 A, [O II] 7319, 7330 A, and [O III] 4959, 5007 A. The oxygen emissions exhibit rest frame expansion velocities of -2200 to +4400 km/s. No other significant broad line emissions were detected including Halpha emission. We discuss possible causes for this unusual spectrum and compare SN 1941C's optical and X-ray luminosities to other evolved CCSNe.

description: Research identifies relationships among weekly alternative marketing arrangement (AMA) prices since the advent of mandatory price reporting in 2001. Relationships between cash prices and other AMA prices, both for fed cattle and hogs, changed little over the twelve years. For fed cattle, cash prices were closer to formula prices and negotiated grid prices than to forward contract prices. For hogs, cash prices were closer to swine market formula prices than to either other market formula prices or other purchase prices. Both for fed cattle and hogs, cash prices were above other AMA prices in upward moving markets and below other AMA prices in downward moving markets. However, there was no indication the thinning negotiated cash market adversely affected these relationships.
Combinatorial optimisation via highly efficient quantum walks
Creators: name: Marsh, Samuel

description: We present a highly efficient quantum circuit for performing continuous time quantum walks (CTQWs) over an exponentially large set of combinatorial objects, provided that the objects can be indexed efficiently. CTQWs form the core mixing operation of a generalised version of the Quantum Approximate Optimisation Algorithm, which works by `steering' the quantum amplitude into high-quality solutions. The efficient quantum circuit holds the promise of finding high-quality solutions to certain classes of NP-hard combinatorial problems such as the Travelling Salesman Problem, maximum set splitting, graph partitioning, and lattice path optimisation.

Variation of the cross section for e+e- --> W+H- in the Minimal Supersymmetric Standard Model

description: We study the loop-induced process e+e- --> W+H- in the Minimal Supersymmetric Standard Model (MSSM). This process allows the charged Higgs boson to be produced in e+e- collisions when its mass is larger than half the center-of-mass energy, so that e+e- --> H+H- is kinematically forbidden. By scanning over the MSSM parameters subject to experimental constraints we examine the range of values possible for this cross section. We find that, in regions of parameter space where this cross section is large enough to be of interest, the contributions from supersymmetric particles typically increase the cross section by 50-100% compared to the non-supersymmetric two Higgs doublet model result. Choosing a few typical MSSM parameter sets, we show the regions in the m_{H^{\pm}}-tan(beta) plane in which at least 10 W^{\pm}H^{\mp} events would be produced at the e+e- collider for m_{H^{\pm}} >= sqrt(s)/2. We also show that including radiative corrections to the MSSM Higgs sector has only a small effect on the cross section.

description: Coordinated motion of cilia is a fascinating and vital aspect of very diverse forms of eukaryotic life, enabling swimming and propulsion of fluid across cellular epithelia. There are many questions still unresolved, and broadly they fall into two classes. (i) the mechanism of how cilia physically transmit forces onto each other. It is not known for many systems if the forces are mainly of hydrodynamical origin, or if elastic forces within the cytoskeleton are important. (ii) In those systems where we know that forces are purely hydrodynamical, we do not have a framework for linking our understanding of how each cilium behaves in isolation to the collective properties of two or more cilia. In this work, we take biological data of cilia dynamics from a variety of organisms as an input for an analytical and numerical study. We calculate the relative importance of external flows versus internal cilia flows on cilia coupling. This study contributes to both the open questions outlined above: firstly, we show that it is, in general, incorrect to infer cilium–cilium coupling strength on the basis of experiments with external flows, and secondly, we show a framework to recapitulate the dynamics of single cilia (the waveform) showing classes that correspond to biological systems with the same physiological activity (swimming by propulsion, versus forming collective waves).This article is part of the theme issue ‘Unity and diversity of ciliary systems in locomotion and transport’.
Variability of Anthropogenic Gases: Nitrogen Oxides, Sulfur Dioxide, Ozone and Ammonia in Kathmandu Valley, Nepal
Creators: name: kiros, filimon
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Background: Kathmandu Valley is one of the largest and most polluted metropolitan regions in the Himalayan foothills. Rapidly expanding urban sprawl and growing fleet of vehicles, and industrial facilities such as brick factories across the valley have led to conditions where ambient concentrations of key gaseous air pollutants are expected to exceed Nepal’s National Ambient Air Quality Standards and World Health Organization guidelines.
Objectives: The aim of this study is to quantify the distribution of gaseous pollutants across the valley characterized by different emission sources, and also assess influence of meteorology in the region on the temporal variability and spatial distribution of these gases, including differences at sites upwind and/or downwind of three major cities in the Kathmandu Valley.
Methods: In order to understand the spatial variation of the trace gases in the Kathmandu Valley, passive samples of SO2, NOx, NO2, NH3, and O3 were simultaneously collected from fifteen locations between March and May 2013. A follow-up study during two separate campaigns in 2014 sampled these gases, except ammonia, one site at a time from thirteen urban, suburban and rural stationary sites.
Results: In 2013, urban sites were observed to have higher weekly averaged NO2 and SO2 (22.4 ± 8.1 µg/m3 and 14.5 ± 11.1 µg/m3, respectively) than sub-urban sites (9.2 ± 3.9 µg/m3 and 7.6 ± 2.8 µg/m3, respectively). Regions located within 3 km of brick factories exhibited higher SO2 concentrations (22.3 ± 14.7 µg/m3) than sites at least than 3 km away (5.8 ± 1.1 µg/m3). Increased NH3 levels were observed at sites downstream from polluted rivers (25.8 ± 5.5 µg/m3) compared to upstream sites (19.9 ± 3.6 µg/m3). Increased O3 was observed in rural locations (108.5 ± 31.4 µg/m3) compared to urban sites (87.1 ± 9.2 µg/m3) (ANOVA, p
Conclusions: Parallel to previous studies that found O3 levels that exceeded guideline, these results suggest that ground-level O3, as its levels frequently exceeded guidelines throughout the sampling periods, is an important concern throughout the valley. NH3 near polluted rivers, NO2 near high traffic activity and SO2 around brick factories are also important pollutants that need more intensive monitoring, primarily due to their importance in particulate matter formation chemistry.

description: The Roper state is extracted with valence overlap fermions on a $2+1$-flavor domain-wall fermion lattice (spacing $a = 0.114$ fm and $m_π = 330$ MeV) using both the Sequential Empirical Bayes (SEB) method and the variational method. The results are consistent, provided that a large smearing-size interpolation operator is included in the variational calculation to have better overlap with the lowest radial excitation. Similar calculations carried out for an anisotropic clover lattice with similar parameters find the Roper $\approx 280$ MeV higher than that of the overlap fermion. The fact that the prediction of the Roper state by overlap fermions is consistently lower than those of clover fermions, chirally improved fermions, and twisted-mass fermions over a wide range of pion masses has been dubbed a "Roper puzzle." To understand the origin of this difference, we study the hairpin $Z$-diagram in the isovector scalar meson ($a_0$) correlator in the quenched approximation. Comparing the $a_0$ correlators for clover and overlap fermions, at a pion mass of 290 MeV, we find that the spectral weight of the ghost state with clover fermions is smaller than that of the overlap at $a = 0.12$ fm and $0.09$ fm, whereas the whole $a_0$ correlators of clover and overlap at $a = 0.06$ fm coincide within errors. This suggests that chiral symmetry is restored for clover at $a \le 0.06$ fm and that the Roper should come down at and below this $a$. We conclude that this work supports a resolution of the "Roper puzzle" due to $Z$-graph type chiral dynamics. This entails coupling to higher components in the Fock space (e.g. $Nπ$, $Nππ$ states) to induce the effective flavor-spin interaction between quarks as prescribed in the chiral quark model, resulting in the parity-reversal pattern as observed in the experimental excited states of $N, Δ$ and $Λ$.
