description: We study the dispersive readout of a qubit in the ultimate limit of a single-photon probe. The use of a single-photon probe avoids the errors due to nonorthogonality of coherent states. A photodetector is used in the scheme we consider. The dynamics of the system is studied using the Heisenberg-Langevin equations. We treat the counter-rotating terms in the Hamiltonian perturbatively, which leads to the Bloch-Siegert shift in the resonator frequency. It is shown how this can improve the readout. The theory of photon transport through the qubit and the resonator it couples to is provided while taking the effect of the counter-rotating terms into account. To calculate the readout contrast, we use two approaches. The first one neglects the qubit relaxation and allows us to derive a compact expression for the contrast. Also, we obtain simple estimates for the system parameters to maximize the contrast. The second approach accounts for the qubit relaxation, which allows us to further improve the contrast. We demonstrate that for a readout time of 1$μ$s, a contrast of more than 75% can be achieved for an ideal detector and single-photon source.

description: In an aging society, it is necessary to detect the cognitive decline of individuals at an early stage using simple measurement methods. This makes early health care possible for those affected. The aim of the study was to develop a classifier for cognitive state in older adults with and without mild cognitive impairment (MCI) based on kinematic parameters of linear and curvilinear aiming arm movements. In a group of 224 older adults over 80 years of age (cognitively healthy and MCI), the movement duration and intersegment intervals of linear and curvilinear arm movements of 20 cm were recorded. Movement duration was significantly longer in the curvilinear condition than in the straight movement, and MCI participants required significantly more time than cognitively healthy participants. Post-hoc analysis on the fluidity of movement in the curvilinear condition showed that MCI men had significantly longer inter-segmental intervals than non-MCI men. No difference was found in women. Based on the inter-segmental intervals, a simple classifier could be developed that correctly classified 63% of the men. In summary, aiming arm movements are only conditionally suitable as a classifier for cognitive states. For the construction of an ideal classifier, age-related degeneration of cortical and subcortical motor areas should be considered.

METER IN FRENCH AND ITALIAN OPERA, 1809–1859
Creators: name: Shea, Nicholas
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Current and historical methods of metric analysis often assume that the first beat of a metric group is stronger than the second. This, however, is not the case in all repertoires. For example, a study by William Rothstein (2011) demonstrates that Verdi’s midcentury operas often place emphasis on even-numbered beats. This paper shows this metric trend to be even more prevalent in a corpus of 208 nineteenth-century operatic excerpts, (1809-1859).
I present a formal model that classifies phrases according to anacrusis length and prosodic accent, showing where large-scale metric accents fall within a phrase. This model produces three metric types which align with Rosthstein’s (2011) previous work. Compositional and historical features (e.g., language, premiere date, librettist, etc.) were tracked alongside type in order to determine whether preferences for certain metric forms were more prevalent in certain contexts. This indeed was the case. For instance, use of even-emphasis meter increases over time, even though odd-emphasis meter remains most common. Individual composers also show a significantly distinguishable preference toward each type of meter. These results not only confirm that the highest concentration of even-emphasis meter occurs in Verdi’s midcentury operas (Rothstein 2011), but that Verdi is the primary user of this type overall. I also demonstrate that language and composer nationality do not significantly affect an excerpt's metric type; only Verdi shows distinction in these areas. With this finding, I argue against using nationalist language to identify metric types and instead propose suggestions that better-reflect an updated understanding of nineteenth-century metric conventions.

Islamophobia, Anti-Semitism, and Censorship: Reflections on Religious and Political Radicalism in John Adams’s The Death of Klinghoffer
Creators: name: Smith, Allison R
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: The issue of anti-Semitism in John Adams’s 1991 opera, The Death of Klinghoffer, has been widely discussed by scholars such as Richard Taruskin, Robert Fink, and others. For instance, Taruskin asserts that Adams favors the Palestinians through musical grandiosity and by describing them as “men of ideals.” However, this fails to consider the possibility that Adams intended to portray an evenhanded view of diverse religious groups. Through close readings of the libretto and select numbers from Klinghoffer, such as the “Chorus of Exiled Palestinians,” the “Chorus of Exiled Jews,” and the “Aria of the Falling Body,” my thesis maintains that Adams treats both sides equally. Although he depicts each group differently through a contrasting approach to text, orchestration, and texture, he nevertheless does not favor one group over the other. Additionally, a close reading of the “Aria of the Falling Body” provides Adams’s possible solution to this conflict – reconciliation between religious communities. Adams does so through portraying Leon Klinghoffer as a scapegoat. This aria is sung by Leon Klinghoffer’s body after he is sacrificed by the Palestinian hijackers – his sacrifice ensured the safety of the remaining passengers on board. Adams thus presents Klinghoffer as religious commentary – not only by vividly depicting the warring religious communities – but also by offering a solution to a centuries-old conflict.
Creating A Community A New Ecological, Economical, and Social Path to Uniting a Community

description: Humans are evolutionarily programmed to respond positively to nature, and maintaining a connection to it is necessary to the health and well being of every individual while we collectively stride for the goal of sustainability. This Thesis proposal will examine land and water restoration through the service of a sustainable community center. Environmentally low impact, organic, and vernacular design will be investigated as a means to heal, site and community with various techniques of resilient applications.
The area of research is the Blackstone River Valley, once the heart of America’s first industrial revolution. Canals, factories and mills bordered the shores of the Blackstone River and left the land and water with a legacy of pollution. The Blackstone River was once known as the most polluted waterway in the country, with extensive toxic sediment that continues to require remediation. The Thesis is located on the former Fisherville Mill site, a brownfield-designated area in the town of Grafton, Massachusetts. This design will be a possible prototype for other mill sites within the Blackstone River Valley by re-inserting an environmental and economic component into the site. The goal will be to return a degraded location into a site that will allow the community to reinvest in a spirit of reverence for their land and water.

description: Majority of the text modelling techniques yield only point-estimates of document embeddings and lack in capturing the uncertainty of the estimates. These uncertainties give a notion of how well the embeddings represent a document. We present Bayesian subspace multinomial model (Bayesian SMM), a generative log-linear model that learns to represent documents in the form of Gaussian distributions, thereby encoding the uncertainty in its co-variance. Additionally, in the proposed Bayesian SMM, we address a commonly encountered problem of intractability that appears during variational inference in mixed-logit models. We also present a generative Gaussian linear classifier for topic identification that exploits the uncertainty in document embeddings. Our intrinsic evaluation using perplexity measure shows that the proposed Bayesian SMM fits the data better as compared to the state-of-the-art neural variational document model on Fisher speech and 20Newsgroups text corpora. Our topic identification experiments show that the proposed systems are robust to over-fitting on unseen test data. The topic ID results show that the proposed model is outperforms state-of-the-art unsupervised topic models and achieve comparable results to the state-of-the-art fully supervised discriminative models.

At leading order, the observables are completely determined in terms of the known excitation energy of the first excited state of $Λ_c$. At next-to-leading order in the combined expansion all heavy baryon observables can be expressed in a model-independent way in terms of two experimentally measurable quantities. We list predictions at leading and next-to-leading order.

A Combined Historical and Sedimentological Reconstruction of Extratropical Cyclone Derived Coastal Flooding in Boston, MA
Creators: name: Stromer, Zachary D
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Many flood risk assessments are based on instrumental records less than a century in length. Sedimentary and historical archives provide the opportunity to extend flood records by several centuries to millennia. In doing so these longer flood records provide opportunities for improving upon current flood risk assessment and gaining additional insight on the various climatic and geomorphic processes that drive changes in flood frequency. Such a reconstruction has not been attempted previously for Boston, MA where extratropical cyclones (ETC) are currently the dominant mechanism of coastal flooding. Here, we present both a historical reconstruction of extreme storm tides to affect Boston Harbor, and an independent geologic assessment of extreme flooding based on flood deposits preserved within the sediments of Bartlett Pond, a back-barrier coastal pond located 60 kilometers south of Boston.
The historical reconstruction presented here identifies events of extreme flooding back to 1723, which are temporally consistent with overwash deposits identified from the sedimentary analysis at Bartlett Pond. Bartlett Pond is beyond the influence of significant dredging, landfill and dam projects within Boston Harbor. The consistency between extreme flood occurrences in Boston and Bartlett Pond therefore suggest that these man-made alterations have had a minimal impact on extreme flooding to the harbor. Additional modeling work is necessary however to provide confirmation on this initial finding. While flooding associated with the Blizzard of 1978 appears to be an anomaly in the modern instrumental record, our new historical/sedimentological record identify 6 additional events of similar size since European colonization, suggesting an under-assessment of the risk of these types of extreme events for Boston by as much as 300%. Additionally, the 1000 yr Bartlett Pond sedimentary reconstruction appears to show an increase in overwash frequency over the last 300 – 500 years when compared to the 500 years prior. A similar increase in ETC flooding has been observed in nearby sedimentological archives from the Gulf of Maine and could possibly be explained by variations in the North Atlantic Oscillation (NAO) and/or changes in sea surface temperature.

description: The Leggett collective excitations for a two-band Fermi gas with s-wave pairing and Josephson interband coupling in the BCS-BEC crossover at finite temperatures are investigated within the Gaussian pair fluctuation approach. Eigenfrequencies and damping factors for Leggett modes are determined in a nonperturbative way, using the analytic continuation of the fluctuation propagator through a branch cut in the complex frequency plane, as in Phys. Rev. Lett. 122, 093403 (2019). The treatment is performed beyond the low-energy expansion, which is necessary when the collective excitation energy reaches the pair-breaking continuum edge. The results are applied in particular to cold atomic gases at the orbital Feshbach resonance and in a regime far from BEC, which can be relevant for future experiments.

description: Within a perturbative scalar QED model recently considered by Brodsky et al., we study how leading-twist Coulomb rescatterings affect the Drell-Yan cross section at small x = x_{target}, and compare to the case of deep inelastic scattering at small x_{B}. We show that in the range where the transverse momentum transferred to the target is large compared to its minimal value $\sim \morder{x}$, Coulomb rescatterings affect the DIS cross section but not the Drell-Yan production rate. This illustrates that the leading-twist parton distribution functions become non-universal when cross sections which are differential in target-related particles are considered.

description: A new sesquiterpene (Prosoterpene, 1) and eleven reported compounds (2–12) of several classes, such as flavonoids, alkaloids, phenolic acids, and long-chain alcohols, were isolated from the BuOH extract of Prosopis africana (Guill. & Perr.) Taub. Compounds 2–10 were reported for the first time from this plant. Isomers 11 and 12 were separated for the first time. Extensive spectroscopic techniques and literature comparisons were used to characterise their structures. Furthermore, compounds 3, 5–8, and 10–12 were performed for anti-glycation and cytotoxicity activities. Compound 3 (quercetin-3-O-α-L-rhamnoside) exhibited moderate anti-glycation activity. All tested compounds were non-cytotoxic against MCF-7 (breast cancer), NCI-H460 (lung cancer), Hela (cervical cancer), and BJ (normal human fibroblast) cell lines.
Storytelling and Values in a Family Business – An Ethnonarrative Study of the Hotel Queen Sophia
Creators: name: Jacquemot, Nicolas
Publisher: name: University of Leicester
Year: 2019
Subjects: Uncategorized

description: Values are the bedrock of family business culture and have great power to shape behaviours, decisions and priorities in these companies. Notwithstanding this, previous research has been unable to fully explain, how values are perceived and passed on in family firms. Additionally, scholars have not yet thoroughly explored the role of storytelling, for values transmission in family companies. Research in this area is important to better understand how values affect ownership, management and work in family firms. This thesis, based on an ethnographic case study of a Swedish hotel, investigates how values are conveyed through storytelling in a family-run business. It also examines how storytelling uncovers different perceptions of values – and how the notion of “family” occurs within the stories. Fieldwork was carried out during a sixmonth period and included participant observation and thirty-three semistructured interviews. Narrative analysis was used to interpret the findings, which reveal that the family and their firm are closely intertwined; the company’s values are strongly linked to the family. It also shows how storytelling plays an important role in transmitting values in the family business. This research makes a substantial contribution to existing knowledge. Firstly, it shows how values are disclosed and passed on in a family business. This increases knowledge of the process through which values are conveyed through storytelling and offers a thorough understanding of the complexity of this process. Secondly, this research reveals how the values of the organisation are embraced and exhibited – i.e. personified – in different ways. It suggests that this personification of values is linked to autonomy, which adds important knowledge to family business, and hospitality, research. Thirdly, this study makes a vital methodological contribution. The ethnonarrative approach and its focus on storytelling allowed for a deeper understanding of how values are conveyed, perceived and personified in family business.

description: We consider a dynamical membrane world in a space-time with scalar bulk matter described by domain walls. Using the solutions to Einstein field equations and Israel conditions we investigate the possibility of having shortcuts for gravitons leaving the wall and returning subsequently. As it turns out, they usually appear under mild conditions. In the comparison with photons following a geodesic inside the brane, we verify that shortcuts exist. For some Universes they are small, but there are cases where shortcuts are effective. In these cases we expect them to play a significant role in the solution of the horizon problem.

description: Transient response of the spin Peltier effect (SPE) in a Pt/yttrium iron garnet junction system has been investigated by means of a lock-in thermoreflectance method. We applied an alternating charge current to the Pt layer to drive SPE through the spin Hall effect, and measured the AC response of the resultant SPE-induced temperature modulation at frequencies ranging from 10 Hz to 1 MHz. We found that the SPE-induced temperature modulation decreases with increasing the frequency when the frequency is >1 kHz. This is a characteristic feature of SPE revealed by the high frequency measurements based on the lock-in thermoreflectance, while previous low frequency measurements showed that the SPE signal is independent of the frequency. We attribute the decrease of the temperature modulation to the length scale of the SPE-induced heat current; by comparing the experimental results with one-dimensional heat conduction calculations, the length scale of SPE is estimated to be 0.94 μm.

description: This article describes the background and conceptual foundations for the creation of autonomous water management authorities, which would be public organizations for residents of an area defined by economic and social considerations and covering an area framed by watershed divides. These authorities would have administrative and financial autonomy and the powers enabling them to conserve, protect and develop water and soil resources in the watersheds in their sphere of influence for the public good. Using the case of Peru as an example, we describe the nature of local, single-purpose governments, justify the need for creating them, and propose -for the case of natural resources- the establishment of a specific type of local government: autonomous authorities.

Electronic and Steric Effects on C–H Activation at Ir and Rh Half-Sandwich Complexes

description: A range of cyclometallated phenylpyridine, phenylNHC and benzylNHC Ir(III) and Rh(III) half-sandwich complexes and their respective ligands have been synthesised. All new compounds were characterised by 1H and 13C NMR spectroscopy, mass spectrometry and several complexes have been structurally characterised by X-ray crystallography. DFT calculations (carried out by the group of Prof. S. A. Macgregor, Heriot-Watt University) are also discussed in Chapter three.Chapter one introduces mechanisms of C–H activation particularly key mechanistic studies on carboxylate-assisted AMLA and CMD mechanisms with Pd(II), and Ir(III) and Rh(III) half-sandwich complexes. Chapters two, three and four describe studies of steric and electronic effects on cyclometallation via AMLA C–H activation at Ir(III) and Rh(III) and Chapter five summarises the overall conclusions. Intermolecular competition experiments with phenylpyridines showed that cyclometallation reactions were faster with electron-donating substituents (Chapter two). However, the thermodynamic selectivity favoured electron withdrawing substituents. Intramolecular competition experiments with phenylimidazolium salts (Chapter three) were difficult to interpret. Under most of the conditions studied, imidazolium C–H activation is rate limiting and phenyl C–H activation was not under kinetic control. DFT calculations suggest that HOAc/chloride exchange as well as the C–H activation step could be contributing to the selectivity. The use of benzylimidazolium salts (Chapter four) which form six-membered metallacycles allowed observation of kinetic selectivity which showed very little electronic preference with no clear trend. For all ligands studied the thermodynamically more stable complexes are formed by cyclometallation on the ring substituted with the more electron-withdrawing group. The meta-substituted ligands are sensitive to steric effects with a thermodynamic preference for the para-isomers except for R = F. All of the experimental work and full characterisation of ligands and complexes are given in Chapter six.

Tarsal claw IV: 0.15. Epigynum length: 0.275. copulatory ducts separated at midpoint, reaching top of primary lobe apex; copulatory ducts constriction located basally; primary pores not visible; stalk short, procurved, joining the primary lobe at the aperture of the dictynoid pore; dictynoid pore triangular; primary lobe light-bulb shaped; secondary lobe present, positioned ventro-basally from the primary lobe; fertilization canal very long, reaching over the dictynoid pore; fertilization duct internally attached to the primary lobe base.
 Distribution. Only reported from the type locality: Amazing Maze Cave (Pecos County, Texas, Fig. 137).
 Remarks. Male unknown. The holotype vial contained the female holotype and one prosoma. Gertsch (1992) considered Cicurina (Cicurella) mirifica as an eyed taxon, along with other epigean species. Examination of the type however suggested that eyes are not functional and the species is clearly a troglobite. See also Cicurina (Cicurella) delrio.

Next-to-leading order corrections to W+2 jet and Z+2 jet production at hadron colliders

description: We report on QCD radiative corrections to the processes p pbar --> W + 2 jets and p pbar --> Z + 2 jets at the Tevatron. These processes are included in the Monte Carlo program MCFM, which allows the calculation of any infra-red finite variable at next-to-leading order. Due to a better theoretical description of jets at next-to-leading order, some distributions exhibit significant corrections. As expected, the unphysical dependence of theoretical predictions upon the renormalization and factorization scales is greatly reduced compared to leading order. As an example of the predictions that may now be made with MCFM, we present a next-to-leading order estimate of the heavy flavor content of jets produced in association with vector bosons.

description: In the context of quantum metrology, optical cavity-QED platforms have primarily been focused on the generation of entangled atomic spin states useful for next-generation frequency and time standards. Here, we report a complementary application: The use of optical cavities to generate non-classical states of light for electric field sensing below the standard quantum limit. We show that cooperative atom-light interactions in the strong collective coupling regime can be used to engineer generalized atom-light cat states which enable quantum enhanced sensing of small displacements of the cavity field even in the presence of photon loss. We demonstrate that metrological gains of 10-20 dB below the standard quantum limit are within reach for current cavity-QED systems operating with long-lived alkaline-earth atoms.

Cheliceral promargin right side with 3 teeth (2 large, 1 small), left side likewise; retromargin right side with 4 denticles (3 large, 1 small), left side with 6 denticles (2 large, 4 small). Leg I: total length: 5.65; femur: 1.60; with long transverse slit, bearing medial, shallow indentation; atrium rectangular, almost intruded by slightly rounded dorsal plate, atrial aperture small; bursa enlarged, not fused; copulatory ducts touching at midpoint, reaching slightly over primary lobe apex; copulatory ducts constriction located medially; primary pores visible (1 seen); stalk short, recurved, joining the primary lobe at the aperture of the dictynoid pore; dictynoid pore large, rounded; primary lobe ear-shaped; secondary lobe absent; fertilization canal short, externally positioned from dictynoid pore; fertilization duct medially attached to the primary lobe base.
 Distribution. Known from two caves in Bexar County (Fig. 134): Elm Spring Cave (=Grubbs Cave ES), and Grubbs Cave No. 23, 8 km NE Helotes.
 Remarks. Male unknown. The exact location of cave no 23 could not be verified and is only approximate (Fig. 134), while Elm Spring Cave is now partially sealed with concrete for safety, and is not accessible. This makes the reassessment of the validity of that species by recollection impossible in the actual conditions. In addition, the specimen from Grubbs Cave No. 23, 8 km NE Helotes could not be located and examined to confirm the occurrence of Cicurina (Cicurella) neovespera in that cave. However, the locality is included in Fig. 134 based on Cokendolpher’s (2004a) record and indicated by an open symbol.

description: The inside of a fusion energy device is one of the most challenging environments known about, with temperatures exceeding 100,000,000 °C in the centre of the plasma. The Heating by Induction to Verify Extremes (HIVE) testing facility at the UK Atomic Energy Authority (UKAEA) uses high heat flux experiments to research and develop plasma-facing components which experience the most severe thermal loads in such a machine. Induction heating is used to deliver up to 20 MW/m2 of surface power to a component while high-pressure coolant passes through it. Performing these experiments is expensive due to their high-power usage and the setup time required by technicians. It is imperative therefore that each experiment provides as much insight as possible about a component’s performance. Experimental parameters, such as induction coil design, frequency or power, are decided based on the memories, experience and gut-feeling of an experienced operator. In the era of High-Performance Computing (HPC), Big Data and Machine Learning (ML) the optimal parameters can be deduced utilising these methods. Moreover, ML algorithms have proved to be excellent at gaining insight from high-dimensional data, which is a common struggle for the human mind. A fully automated Virtual Twin (VT) of HIVE has been developed using VirtualLab, an open-source package created by the authors used to perform virtual experiments. Simulation results provide data points across the parameter space which VirtualLab’s ML routine can use to gain valuable insight, including the optimal experimental parameters. Utilising VirtualLab’s multi-node and High Throughput Computing (HTC) capabilities, a large number of simulations are performed for a variety of experimental parameters in a very short space of time, allowing rapid iterations of the engineering design cycle. This is an example of human-machine collaboration guiding, but not making, decisions which is becoming an increasingly important and useful tool in a wide variety of fields.
The Optimization of Offshore Wind Turbine Towers Using Passive Tuned Mass Dampers
Creators: name: YILMAZ, ONUR CAN
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: Increasing energy demand and carbon emissions have driven the development of alternative energy solutions. One promising technology is wind energy. Wind energy technology developments has advanced substantially since the 1980s. Offshore wind turbines have become a major research focus, due to the promising offshore wind resource. However, challenges in offshore wind energy have arisen due to the additional wave loading and strong wind loads. Structural control systems have been implemented and researched in order to decrease dynamic response of these systems. The previous studies were successful at decreasing fatigue loads in the tower and support structure of offshore wind turbines. Giving these results, it is still unknown if the reduced loading enabled by structural control systems can allow for reduced material costs in the major structural components.
This research examines on an offshore wind turbine's tower-monopile structure by adding several configurations of passive tuned mass dampers, while simultaneously reducing the thickness of the structure in order to reduce costs. A range of candidate tower-monopile systems are created, and simulated in FAST-SC with and without passive tuned mass dampers. Fatigue and ultimate loads are calculated and analyzed. A variety of design criteria are considered including fatigue and ultimate loads, as well as local and global buckling. The results demonstrate that the tower-monopile thickness may be reduced up to 6.2% and still satisfy all design criteria.
Canonical analysis with no second-class constraints of $BF$ gravity with Immirzi parameter

description: In this paper we revisit the canonical analysis of $BF$ gravity with the Immirzi parameter and a cosmological constant. By examining the constraint on the $B$ field, we realize that the analysis can be performed in a Lorentz-covariant fashion while utterly avoiding the introduction of second-class constraints during the whole process. Finally, we make contact with the description of the phase space of first-order general relativity in terms of canonical variables with manifest Lorentz covariance subject to first-class constraints only recently introduced.

Correcting the Minimization Bias in Searches for Small Signals
Creators: name: Rolke, Wolfgang A.
name: Lopez, Angel M.
Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We discuss a method for correcting the bias in the limits for small signals if those limits were found based on cuts that were chosen by minimizing a criterion such as sensitivity. Such a bias is commonly present when a "minimization" and an "evaluation" are done at the same time. We propose to use a variant of the bootstrap to adjust the limits. A Monte Carlo study shows that these new limits have correct coverage.
