description: It has been a long-standing debate that why quantum mechanics uses complex numbers but not only real numbers. To address this topic, in recent years, the imaginarity theory has been developed in the way of quantum resource theory. However, the existing imaginarity theory mainly focuses on the quantum systems with finite dimensions. Gaussian states are widely used in many fields of quantum physics, but they are in the quantum systems with infinite dimensions. In this paper we establish a resource theory of imaginarity for bosonic Gaussian states. To do so, under the Fock basis, we determine the real Gaussian states and real Gaussian channels in terms of the means and covariance matrices of Gaussian states. Also, we provide two imaginary measures for Gaussian states based on the fidelity.

Markets, Morality, and the Media: The Election of 1884 and the Iconography of Progressivism

description: The victory of Democrat Grover Cleveland over Republican James G. Blaine in the presidential election of 1884 is one of those events in U.S. history that once commanded broad attention but has long since ceased to stir the blood. This was an epoch, after all, about which historians customarily play up the radical transformations being wrought by big business and downplay the influence of presidential administrations on public policy. In the conventional narrative—familiar to contemporaries, and updated a half century later for a generation of New Dealers by the journalist-turned-popular historian Matthew Josephson—greedy "robber barons" called the shots, while unscrupulous "politicos" did their bidding. This big-business-centric narrative has proved remarkably durable and helps explain why generations of historians have—misleadingly, in my view—borrowed a phrase from Mark Twain and called the period between the end of Congressional Reconstruction in 1877 and the emergence of the Progressive movement around 1900 the Gilded Age.
The Transnational Dimension of Statutory Interpretation – Tragically Overlooked in a Global Commercial Environment

Year: 2019

description: Recently, we came across a very well written and thoroughly researched article by Dharmananda and Firios entitled “Interpreting statutes and contracts: A distinction without a difference?”. The article made many excellent points and was very thought provoking – but it overlooked an aspect of legal interpretation which is central to the modern legal landscape, namely internationalisation. In all areas of law – arguably, especially in our field of commercial regulation – the regulatory effects of globalisation and harmonisation necessitate a different perspective on both statutory and contractual interpretation. We do not disagree with the paper’s overarching conclusion that there are important parallels between contractual and legislative interpretation – but we posit that in the formula to establish this point it becomes increasingly important to include the international dimension. Not all domestic statues should be seen in a solely domestic light.

description: Ineffective communication and omitting clinical information can occur during patient care. A particularly vulnerable period for this breakdown is during the transfer of care (handoff) from the operating room (OR) to the post-anesthesia care unit (PACU). It can jeopardize patient safety, compromise work efficiency, and decrease patient and staff satisfaction. Despite mandates for a handoff process by The Joint Commission (TJC), the American Association of Nurse Anesthesiology (AANA), and the American Society of Anesthesiologists (ASA), there continues to be a lack of consensus on a standardized handoff tool. Checklists have proven effective in healthcare crises and the aviation industry, assisting decision-making. The aims of this project were to revise the OR to PACU Anesthesia Handoff Report Checklist (OPAHRC) for clinical implementation using the Delphi method at Kaiser Permanente West Los Angeles (KPWLA). We recruited an expert panel of Certified Registered Nurse Anesthetists (CRNAs) to participate in two Delphi rounds. We received 31 responses from participants throughout a three month period. In an iterative process, we analyzed feedback after each round and edited the checklist based on expert opinion and group consensus. Qualitative results included five common themes for essential elements during an anesthesia handoff, and 68% of respondents (N=21) described the checklist as "concise and thorough as is." Quantitative data results included a greater than 50% consensus in all 20 Likert-scale questions. This high level of group consensus from the surveys supported the suitability of the OPAHRC for implementation at KPWLA. This tool can potentially improve the handoff process and patient safety.

description: In 1962 Dyson used a physically based, macroscopic argument to deduce the first two terms of the large spacing asymptotic expansion of the gap probability for the bulk state of random matrix ensembles with symmetry parameter β. In the ensuing years, the question of asymptotic expansions of spacing distributions in random matrix theory has shown itself to have a rich mathematical content. As well as presenting the main known formulas, we give an account of the mathematical methods used for their proofs, and provide some new formulas. We also provide a high precision numerical computation of one of the spacing probabilities to illustrate the accuracy of the corresponding asymptotics.

Human dietary and mobility patterns of a prehistoric population from Sigatoka, Fiji : a reconstruction using stable isotope analysis
Creators: name: Phaff, Brianne Nicole
Publisher: name: University of British Columbia
Year: 2012

description: This thesis will explore dietary change and human movement/migration patterns of prehistoric humans interred at the site of Sigatoka, Viti Levu, Fiji through the isotope analysis of human and faunal skeletal material. Our dataset includes human tooth enamel and bone collagen samples of 52 individuals interred at the western and eastern burial groups at Sigatoka, which span four discrete periods of occupation, as well as a series of faunal remains excavated from the site. The aim of this study was to investigate (1) the proportion of marine versus terrestrial protein fraction of the diet through an analysis of stable carbon (δ¹³C) and nitrogen (δ¹⁵N) values of human bone collagen; (2) the fraction of local versus foreign individuals at the site through an analysis of strontium (⁸⁷Sr/⁸⁶Sr) values in human tooth enamel; and (3) differences in diet in relation to sex, age, or place of birth through a comparison of isotopic values with previous osteological and mortuary analyses of the burials at Sigatoka. The results of our analyses suggest a diet consisting of mixed marine/terrestrial resources, and while the majority of individuals appear to be local, twelve individuals produced non-local strontium signatures relative to local bioavailable strontium values. Although no clear patterns of diet or mobility in relation to age, sex, or occupation period were revealed, our results imply that both marine and terrestrial resources played an important part in the subsistence strategies of prehistoric Fijians, and that some inter or intra-island migration was occurring.

description: The strong coherent coupling of quantum emitters to vacuum fluctuations of the light field offers opportunities for manipulating the optical and transport properties of nanomaterials, with potential applications ranging from ultrasensitive all-optical switching to creating polariton condensates. Often, ubiquitous decoherence processes at ambient conditions limit these couplings to such short time scales that the quantum dynamics of the interacting system remains elusive. Prominent examples are strongly coupled exciton-plasmon systems, which, so far, have mostly been investigated by linear optical spectroscopy. Here, we use ultrafast two-dimensional electronic spectroscopy to probe the quantum dynamics of J-aggregate excitons collectively coupled to the spatially structured plasmonic fields of a gold nanoslit array. We observe rich coherent Rabi oscillation dynamics reflecting a plasmon-driven coherent exciton population transfer over mesoscopic distances at room temperature. This opens up new opportunities to manipulate the coherent transport of matter excitations by coupling to vacuum fields.

description: Recent signs of a Standard Model-like Higgs at 125 GeV point towards large A-terms in the MSSM. This presents special challenges for gauge mediation, which by itself predicts vanishing A-terms at the messenger scale. In this paper, we review the general problems that arise when extending gauge mediation to achieve large A-terms, and the mechanisms that exist to overcome them. Using these mechanisms, we construct weakly-coupled models of low-scale gauge mediation with extended Higgs-messenger couplings that generate large A-terms at the messenger scale and viable mu/B_mu-terms. Our models are simple, economical, and complete realizations of supersymmetry at the weak scale.

First year site fidelity and survival in reintroduced captive-bred Vancouver Island marmots (Marmota vancouverensis)
Creators: name: Jackson, Cheyney L.
Publisher: name: University of British Columbia
Year: 2012

description: The Vancouver Island marmot is a critically endangered sciurid endemic to British Columbia, Canada. By 1997, the species had collapsed to fewer than 150 individuals in total. Between 2003 and 2010, 301 captive-bred marmots were implanted with radiotelemetry transmitters and released to new sites and extinct colonies to supplement the wild population. I evaluated reintroduction success based on three short-term measures: first season fidelity to release site, active season survival from release to hibernation, and overwinter survival through early spring. I used generalized linear mixed models to evaluate the influence of sex and age, release practices and procedures, and the local and landscape-level attributes of release habitats on site fidelity and survival. Results suggested that poor overwinter survival has been the limiting factor in first-year reintroduction success. In all years, overwinter survival was lower for newly released captive-bred marmots than for their wild or previously-released counterparts. Release date was the variable most predictive of success, but was positively associated to site fidelity and active season survival and negatively associated to overwinter survival. Release date was the only predictor for overwinter survival, whereas site fidelity was also negatively impacted by the presence of resident females at the release site. Active season survival was highest for females, 2-year olds, and marmots released to sites with talus. I discuss these results in the context of current release practices for Vancouver Island marmots, and make recommendations for future release candidates, site characteristics, and release procedures.

description: We review the non-trivial issue of the relativistic description of a quantum mechanical system that, contrary to a common belief, kept theoreticians busy from the end of 1920s to (at least) mid 1940s. Starting by the well-known works by Klein-Gordon and Dirac, we then give an account of the main results achieved by a variety of different authors, ranging from de Broglie to Proca, Majorana, Fierz-Pauli, Kemmer, Rarita-Schwinger and many others. A particular interest comes out for the general problem of the description of particles with \textit{arbitrary} spin, introduced (and solved) by Majorana as early as 1932, and later reconsidered, within a different approach, by Dirac in 1936 and by Fierz-Pauli in 1939. The final settlement of the problem in 1945 by Bhabha, who came back to the general ideas introduced by Majorana in 1932, is discussed as well, and, by making recourse also to unpublished documents by Majorana, we are able to reconstruct the line of reasoning behind the Majorana and the Bhabha equations, as well as its evolution. Intriguingly enough, such an evolution was \textit{identical} in the two authors, the difference being just the period of time required for that: probably few weeks in one case (Majorana), while more than ten years in the other one (Bhabha), with the contribution of several intermediate authors. Majorana's paper of 1932, in fact, contrary to the more complicated Dirac-Fierz-Pauli formalism, resulted to be very difficult to fully understand (probably for its pregnant meaning and latent physical and mathematical content): as is clear from his letters, even Pauli (who suggested its reading to Bhabha) took about one year in 1940-1 to understand it. This just testifies for the difficulty of the problem, and for the depth of Majorana's reasoning and results.

description: This paper reports the first ATLAS measurement of the $B_s^0 \to μμ$ effective lifetime. The measurement is based on the data collected in 2015-2016, amounting to 26.3 fb$^{-1}$ of 13 TeV LHC proton-proton collisions. The proper decay-time distribution of $58\pm13$ background-subtracted signal candidates is fit with simulated signal templates parameterised as a function of the $B_s^0$ effective lifetime, with statistical uncertainties extracted through a Neyman construction. The resulting effective measurement of the $B_s^0 \to μμ$ lifetime is $0.99^{+0.42}_{-0.07} \, (\text{stat.})\pm 0.17 \text{ (syst.)}\,\mathrm{ps}$ and it is found to be consistent with the Standard Model.

description: We show that there are two reasons why the partial width for the transition $Γ_1(Υ(3S)\rightarrow γχ_{b1}(1P))$ is suppressed. Firstly, the spin-averaged matrix element (m.e.) $\bar{I(3S|r|1P_J)}$ is small, being equal to 0.023 GeV$^{-1}$ in our relativistic calculations. Secondly, the spin-orbit splittings produce relatively large contributions, giving $I(3S|r|1P_2)=0.066$ GeV$^{-1}$, while due to large cancellation the m.e. $I(3S|r|1P_1)=-0.020$ GeV$^{-1}$ is small and negative; at the same time the magnitude of $I(3S|r|1P_0)=-0.063$ GeV$^{-1}$ is relatively large. These m.e. give rise to the partial widths: $Γ_2(Υ(3S)\rightarrow γχ_{b2}(1P))=212$ eV, $Γ_0(Υ(3S)\rightarrow γχ_{b0}(1P))=54$ eV, which are in good agreement with the CLEO and BaBar data, and also to $Γ_1(Υ(3S)\rightarrow γχ_{b1}(1P))=13$ eV, which satisfies the BaBar limit, $Γ_1(exp.) < 22$ eV.

description: We present experimental results obtained for a one-dimensional flow using high precision motion capture. The full pedestrians' trajectories are obtained. In this paper, we focus on the fundamental diagram, and on the relation between the instantaneous velocity and spatial headway (distance to the predecessor). While the latter was found to be linear in previous experiments, we show that it is rather a piecewise linear behavior which is found if larger density ranges are covered. Indeed, our data clearly exhibits three distinct regimes in the behavior of pedestrians that follow each other. The transitions between these regimes occur at spatial headways of about 1.1 and 3 m, respectively. This finding could be useful for future modeling.

description: The energetics of thin elongated ferromagnetic nano-islands is considered for some different shapes, aspect ratios, and applied magnetic field directions. These nano-island particles are important for artificial spin-ice materials. For low temperature, the magnetic internal energy of an individual particle is evaluated numerically as a function of the direction of a particle's net magnetization. This leads to estimations of effective anisotropy constants for (1) the easy axis along the particle's long direction, and (2) the hard axis along the particle's thin direction. A spin relaxation algorithm together with fast Fourier transform for the demagnetization field is used to solve the micromagnetics problem for a thin system. The magnetic hysteresis is also found. The results indicate some possibilities for controlling the equilibrium and dynamics in spin-ice materials by using different island geometries.

Private Enterprise, Public Good? Communications Deregulation as a National Political Issue, 1839-1851

description: Building on recent scholarship on social relationships and cultural norms, this essay shows how the study of national political issues can raise larger questions about American public life. In particular, it reveals that, even in the supposed heyday of laissez-faire, private enterprise remained a contested ideal. Not until the 1840s would public figures begin even to acknowledge the possibility that large-scale, nationwide enterprises, such as the postal system or the telegraph network, could be coordinated by institutions other than the federal government. The significance of this perceptual shift is often overlooked.

The Bootstrap Program for Defect CFT
Creators: name: Liendo Cordova, Pedro
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2019

description: Extended objects or "defects" are of fundamental importance in CFT, examples include boundaries, interfaces, and surface defects, and also Wilson and 't Hooft lines in gauge theories. In this talk we will give an overview of the bootstrap program applied to defect CFTs. We will present a version of crossing symmetry analogous to crossing symmetry for four-point functions in bulk CFTs, and explain how to constrain theories with it. Established results will be discussed, and also some open problems.
No coincidence of center percolation and deconfinement in SU(4) lattice gauge theory

description: We study the behavior of center sectors in pure SU(4) lattice gauge theory at finite temperature. The center sectors are defined as spatial clusters of neighboring sites with values of their local Polyakov loops near the same center elements. We study the connectedness and percolation properties of the center clusters across the deconfinement transition. We show that for SU(4) gauge theory deconfinement cannot be described as a percolation transition of center clusters, a finding which is different from pure SU(2) or pure SU(3) Yang Mills theory, where the percolation description even allows for a continuum limit.

Wilson loop correlators at strong coupling in $\mathcal{N}=2$ quiver gauge theories
Creators: name: Pini, Alessandro

Year: 2023
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider 4-dimensional $\mathcal{N} = 2$ superconformal quiver theories with $SU(N)^M$ gauge group and bi-fundamental matter and we evaluate correlation functions of $n$ coincident Wilson loops in the planar limit of the theory. Exploiting specific untwisted/twisted combinations of these operators and using supersymmetric localization, we are able to resum the whole perturbative expansion and find exact expressions for these correlators that are valid for all values of the 't Hooft coupling. Moreover, we analytically derive the leading strong coupling behaviour of the correlators, showing that they obey a remarkable simple rule. Our analysis is complemented by numerical checks based on a Padé resummation of the perturbative series.

Telegraph

description: The Electro Magnetic Telegraph—A Great Revolution Approaching.' So ran the headline of a glowing editorial that James Gordon Bennett featured in the New York Herald in May 1845. Though the country's first telegraph link—a forty-mile line between Washington, D.C., and Baltimore—had been open to the public on a fee-for-service basis for only a month, and while New York City had yet to be linked with the nation's capital, it seemed self-evident to Bennett that the new medium was destined to have 'the most extraordinary effects.' Prominent among them would be the rapid obsolescence of the handwritten letter. Now that the public had an alternative to the post office, Bennett predicted, the 'present system of epistolary correspondence' would be 'entirely revolutionized' and the 'mail system' entirely 'broken up.' Who in the future would bother to pen a handwritten letter that might take days to arrive, now that it had become possible to communicate immediately over the wires?
title: The fate of winter flounder larvae spawned in coastal waters of the Gulf of Maine
Creators: name: DeCelles, Greg

Subjects: Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Historically, winter flounder (Pseudopleuronectes americanus) in the Gulf of Maine were considered to be obligate estuarine spawners. This spawning strategy is thought to promote the formation of relatively isolated subpopulations of flounder in estuaries and bays along the coast. Recent evidence, however, has documented the presence of contingent groups of winter flounder that spawn in coastal, rather than estuarine habitats. Although it is likely that coastal spawning increases gene flow and connectivity between meta-populations, the transport of larvae originating in coastal waters has not been studied to date. To address this question, a coupled biophysical individual-based model is being used to track the transport and development of larvae spawned in three coastal regions of the Gulf of Maine. Velocity data generated by the Finite Volume Coastal Ocean Model (FVCOM) is being used to simulate the Lagrangian trajectory of each larva within the physical domain over a period of 60 days. Settlement success is calculated as the average time spent by each particle in suitable habitats (waters <20 m) over the last 18 days of its larval period, and success is averaged over all particles from each release site. Settlement areas have been delineated geographically, and connectivity matrices are being used to estimate rates of settlement success between spawning grounds and nursery areas. The results of this model will offer insight into the population structure of this species in the Gulf of Maine, and will improve the information available for spatially specific management of this species.
The Age of the Milky Way Inner Halo
Creators: name: Kalirai, Jason
Publisher: name: arXiv
Year: 2012
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The Milky Way galaxy is observed to have multiple components with distinct properties, such as the bulge, disk, and halo. Unraveling the assembly history of these populations provides a powerful test to the theory of galaxy formation and evolution, but is often restricted due to difficulties in measuring accurate stellar ages for low mass, hydrogen-burning stars. Unlike these progenitors, the "cinders" of stellar evolution, white dwarf stars, are remarkably simple objects and their fundamental properties can be measured with little ambiguity from spectroscopy. Here I report observations and analysis of newly formed white dwarf stars in the halo of the Milky Way, and a comparison to published analysis of white dwarfs in the well-studied 12.5 billion-year-old globular cluster Messier 4. From this, I measure the mass distribution of the remnants and invert the stellar evolution process to develop a new relation that links this final stellar mass to the mass of their immediate progenitors, and therefore to the age of the parent population. By applying this technique to a small sample of four nearby and kinematically-confirmed halo white dwarfs, I measure the age of local field halo stars to be 11.4 +/- 0.7 billion years. This age is directly tied to the globular cluster age scale, on which the oldest clusters formed 13.5 billion years ago. Future (spectroscopic) observations of newly formed white dwarfs in the Milky Way halo can be used to reduce the present uncertainty, and to probe relative differences between the formation time of the last clusters and the inner halo.

description: This chapter surveys the history of telecommunications from a global perspective and highlights three influential interpretative traditions. It has two parts. The first part defines “telecommunications” and sketches the main dimensions of four telecommunications networks over a two-hundred-year period—the optical telegraph, the electric telegraph, the landline telephone, and the mobile telephone (and its predecessor, the wireless telegraph). The second part shows how historical scholarship on topics in the history of telecommunications has been shaped by three intellectual traditions: the Large Technical Systems (LTS) approach; political economy; and the Social Construction of Technology (SCOT).
Effect of long-range hopping on dynamic quantum phase transitions of an exactly solvable free-fermion model: Nonanalyticities at almost all times

description: In this work, we investigate quenches in a free-fermion chain with long-range hopping which decay with the distance with an exponent $ν$ and has range $D$. By exploring the exact solution of the model, we found that the dynamic free energy is non-analytical, in the thermodynamic limit, whenever the sudden quench crosses the equilibrium quantum critical point. We were able to determine the non-analyticities of dynamic free energy $f(t)$ at some critical times $t^{c}$ by solving nonlinear equations. We also show that the Yang-Lee-Fisher (YLF) zeros cross the real-time axis at those critical times. We found that the number of nontrivial critical times, $N_{s},$ depends on $ν$ and $D$. In particular, we show that for small $ν$ and large $D$ the dynamic free energy presents non-analyticities in any time interval $Δt\sim1/D\ll1$, i.e., there are \emph{non-analyticities at almost all times}. For the spacial case $ν=0$, we obtain the critical times in terms of a simple expression of the model parameters and also show that $f(t)$ is non-analytical even for finite system under anti-periodic boundary condition, when we consider some special values of quench parameters. We also show that, generically, the first derivative of the dynamic free energy is discontinuous at the critical time instant when the YLF zeros are non-degenerate. On the other hand, when they become degenerate, all derivatives of $f(t)$ exist at the associated critical instant.
