description: Magnetic properties of the substitution series Ru$_{1-x}$Cr$_x$Cl$_3$ were investigated to determine the evolution from the anisotropic Kitaev magnet $α$-RuCl$_3$ with $J_{\rm eff} = 1/2$ magnetic Ru$^{3+}$ ions to the isotropic Heisenberg magnet CrCl$_3$ with $S = 3/2$ magnetic Cr$^{3+}$ ions. Magnetization measurements on single crystals revealed a reversal of the magnetic anisotropy under doping, which we argue to arise from the competition between anisotropic Kitaev and off-diagonal interactions on the Ru-Ru links and approximately isotropic Cr-Ru and isotropic Cr-Cr interactions. In addition, combined magnetization, ac susceptibility and specific-heat measurements clearly show the destabilization of the long-range magnetic order of $α$-RuCl$_3$ in favor of a spin-glass state of Ru$_{1-x}$Cr$_x$Cl$_3$ for a low doping of $x\backsimeq0.1$. The corresponding freezing temperature as a function of Cr content shows a broad maximum around $x\backsimeq0.45$.

description: An overview of the authors results is given. Property C for ODE is defioned, It is proved that the pair of Sturm-Liouville operators has property C. This property is applied to many inverse problems. Some well-known results, such as uniqueness of the recovery of the potential from scattering data, from the spectral function and from two spectra are proved in a new short way based on property C. Many new results are obtained. In particular, it is proved that a compactly supported potential can be uniquely recovered from the phase shift of s-wave alone, known at all energies, without knowledge of bound states and norming constants. The fixed-energy phase shifts known at some values of the angular momentum determine a compactly supported potential uniquely. Mixed data inverse problems are studied. Analysis of the Newton-Sabatier procedure is given. It is shown that this procedure is a parameter-fitting procedure rather than an inversion method. Other results on inverse problems are obtained.

description: Genus Monoxia LeConte, 1865
Monoxia LeConte, 1865: 221
(type species Galleruca angularis LeConte, 1859, by subsequent designation of Blake 1939).
Remarks
This genus contains 15 described species, distributed from Canada to Guatemala. See Fig. 35 for a habitus illustration. See Blake (1939) for a key to the species. However, realize that one species from Texas has been named subsequent to that key, and the generic placement of the old species from Guatemala warrants reevaluation (Riley 2020). All species of Monoxia are rather similar to each other, although easily separating into two groups, those with slender, dorsoventrally flattened aedeagi, and those with more robust aedeagi. Whereas most of the species have bifid claws in the male and simple claws in the female, the anomalous species M. schizonycha Blake, 1939 has bifid claws in both genders. Four species formerly included in the genus are herein transferred to Yingabruxia gen. nov.

description: Raman measurements in the 1.5 - 20 cm-1 energy range were performed on single crystals of Sr_{14-x}Ca_xCu_{24}O_{41}. A quasielastic scattering peak (QEP) which softens with cooling is observed in the polarization parallel to the ladder direction for samples with x = 0, 8 and 12. The QEP is a Raman fingerprint of pinned collective density wave excitations screened by uncondensed carriers. Our results suggest that transport in metallic samples, which is similar to transport in underdoped high-T_c cuprates, is driven by a collective electronic response.

description: We continue here the analysis of the previous paper of the Wheeler-DeWitt constraint operator for four-dimensional, Lorentzian, non-perturbative, canonical vacuum quantum gravity in the continuum. In this paper we derive the complete kernel, as well as a physical inner product on it, for a non-symmetric version of the Wheeler-DeWitt operator. We then define a symmetric version of the Wheeler-DeWitt operator. For the Euclidean Wheeler-DeWitt operator as well as for the generator of the Wick transform from the Euclidean to the Lorentzian regime we prove existence of self-adjoint extensions and based on these we present a method of proof of self-adjoint extensions for the Lorentzian operator. Finally we comment on the status of the Wick rotation transform in the light of the present results.

description: Computational uncertainty quantication in a probabilistic setting is a special case of a parametric problem. Parameter dependent state vectors lead via association to a linear operator to analogues of covariance, its spectral decomposition, and the associated Karhunen-Loève expansion. From this one obtains a generalised tensor representation. The parameter in question may be a tuple of numbers, a function, a stochastic process, or a random tensor field. The tensor factorisation may be cascaded, leading to tensors of higher degree. When carried on a discretised level, such factorisations in the form of low-rank approximations lead to very sparse representations of the high dimensional quantities involved. Updating of uncertainty for new information is an important part of uncertainty quantification. Formulated in terms or random variables instead of measures, the Bayesian update is a projection and allows the use of the tensor factorisations also in this case.

description: It was recently shown that a coherent oscillation of an axion can cause an efficient parametric resonance, leading to a prominent emission of the gravitational waves (GWs). In this paper, conducting the Floquet analysis, we investigate the parametric resonance instability, which potentially triggers the emission of the GWs from axions. Such a resonance instability takes place, when the time evolution of the background field significantly deviates from the harmonic oscillation. Therefore, the resonance instability cannot be described by the Mathieu equation, whose stability/instability chart is well known. In this paper, introducing an explicitly calculable parameter $\tilde{q}$, which can be used to classify different types of the parametric resonance described by the general Hill's equation, we investigate the stability/instability chart for the general Hill's equation. This can also apply to the case where the background oscillation is anharmonic. We show that the flapping resonance instability, which takes place for $\tilde{q}=O(1)$, typically leads to the most significant growth of the inhomogeneous modes among the self-resonance instability. We also investigate whether the flapping resonance takes place for the cosine potential or not.

description: An ASTM International subcommittee on Respiratory Protection, F23.65 is currently developing a consensus standard for assessing respirator fit capability (RFC) criteria of half-facepiece air-purifying particulate respirators. The objective of this study was to evaluate if the test methods being developed for half-facepiece respirators can reasonably be applied to nonpowered full-facepiece–air-purifying respirators (FF–APR). Benchmark RFC test data were collected for three families of FF–APRs (a one-size-only family, a two-size family, and a three-size family). All respirators were equipped with P100 class particulate filters. Respirators were outfitted with a sampling probe to collect an in-mask particle concentration sample in the breathing zone of the wearer. Each of the six respirator facepieces was tested on the National Institute for Occupational Safety and Health 25-subject Bivariate Panel. The RFC test assessed face seal leakage using a PortaCount fit test. Subjects followed the corresponding Occupational Safety and Health Administration-accepted fit test protocol. Two donnings per subject/respirator model combination were performed. The panel passing rate (PPR) (number or percentage of subjects in the panel achieving acceptable fit on at least one of two donnings) was determined for each respirator family at specified fit factor passing levels of 500, 1,000, and 2,000. As a reasonable expectation based on a previous analysis of alpha and beta fit test errors for various panel sizes, the selected PPR benchmark for our study was >75%. At the fit factor passing level of 500 obtained on at least one of two donnings, the PPRs for three-, two-, and one-size families were 100, 79, and 88%, respectively. As the fit factor passing criterion increased from 500 to 1,000 or 2,000, PPRs followed a decreasing trend. Each of the three tested families of FF–APRs are capable of fitting ≥75% of the intended user population at the 500 fit factor passing level obtained on at least one of two donnings. The methods presented here can be used as a reference for standards development organizations considering developing RFC test requirements.

description: The purpose of this study was to assess African American parents’ and caregivers’ perceptions about ADHD, diagnosis, treatment, and outcomes to determine if and/or how those views may affect diagnosis and treatment rates among African American youth. ADHD prevalence is increasing overall in the US across all races/ethnicities, but ADHD diagnosis and treatment rates are still low among African American youth compared to White youth. While African American youth may be more greatly affected by the disorder than White youth, there is a gap in understanding why some parents seek help for their child’s ADHD related behaviors, while others do not. African American parents and primary caregivers of boys ages 5-14 who attended an afterschool program in Harlem, New York City, participated in a cross-sectional design interview study with 43 participants. Transcripts were audio-recorded, transcribed and analyzed using an inductive approach. Highlights of findings included parents’ and caregivers’ discomfort using medication to treat ADHD, concerns about labeling/stigma and misconceptions about ADHD, diagnosis, and treatment. Implications for practice included the need for: disseminating accurate and relevant information, improving understanding about proven and promising non-pharmacological treatment methods and addressing discriminatory practices in ADHD treatment. Recommendations for research include creating and evaluating culturally sensitive treatment approaches, exploring why certain families are misinformed about ADHD, finding effective ways to correct misconceptions, and testing alternative ways to educate healthcare and education professionals on how best to work with African American and other underserved communities.

description: The primary purpose of this study was to investigate the subjective and objective career success perceptions of music school graduates who now identify as professional musicians. This study approached that purpose in four ways. First, the study examined how musicians conceptualized success compared to the literature. Second, the study investigated how musicians conceptualize how success is shown in themselves relative to how it appears in others. Third, the study examined if and how musicians attribute the success that they have achieved in their careers to the institutional preparation they received at academic institutions. Fourth, the study investigated the possibility that geography may play a role in sculpting the perceptual values and qualifiers of success in musicians. This study was informed by the literature surrounding the area of careers, career success, career development as it pertains to musicians, and career success as it pertains to musicians. A survey was the research tool utilized for this descriptive study, and the survey was constructed and facilitated via Qualtrics Software. The survey included 26 Likert-type questions and seven open-ended questions. The sample population used for this study was 326 participants from the New York City Chapter of the American Federation of Musicians Union. The data that was collected from the survey was organized, analyzed, and synthesized to discover emerging themes and answers to the guiding research questions. The findings of this study suggest that musicians understand and value the points of the comparison that those outside of the field of music may use to value and evaluate their own careers. The findings of this study also suggest that musicians may perceive some of the underlying components that make up career success differently in themselves that they do in others. Further, support is provided in this dissertation for the understanding that objective career success and subjective career success are linked in a way that is underrepresented in the literature, and thus is underrepresented in the discussion of the two concepts.

description: The ohmic decay of magnetic fields confined within the crust of neutron stars is considered by incorporating the effect of space-time curvature produced by the intense gravitational field of the star. It is shown that general relativistic effect reduces the magnetic field decay rate substaintially and specially at the late time of the evolution the decay rate decreases by several orders of magnitude when compared with the case without the relativistic effect.

description: The Astrophysical Multimessenger Observatory Network (AMON) has been built with the purpose of enabling near real-time coincidence searches using data from leading multimessenger observatories and astronomical facilities. Its mission is to evoke discovery of multimessenger astrophysical sources, exploit these sources for purposes of astrophysics and fundamental physics, and explore multimessenger datasets for evidence of multimessenger source population AMON aims to promote the advancement of multimessenger astrophysics by allowing its participants to study the most energetic phenomena in the universe and to help answer some of the outstanding enigmas in astrophysics, fundamental physics, and cosmology. The main strength of AMON is its ability to combine and analyze sub-threshold data from different facilities. Such data cannot generally be used stand-alone to identify astrophysical sources. The analyses algorithms used by AMON can identify statistically significant coincidence candidates of multimessenger events, leading to the distribution of AMON alerts used by partner observatories for real-time follow-up that may identify and, potentially, confirm the reality of the multimessenger association. We present the science motivation, partner observatories, implementation and summary of the current status of the AMON project.

description: Employee engagement is a topic that has been widely studied over the course of the past 30 years.  Its potential value to healthcare organizations has only begun to be recognized within the most recent decade.  Numerous studies have been conducted which demonstrate that increased employee engagement contributes to improved patient outcomes, including decreased mortality and hospital acquired conditions as well as increased patient experience scores.  Despite the plethora of literature available documenting the drivers of, barriers to, and outcomes associated with employee engagement hospitals have struggled to gain traction in increasing their scores.  Many experts in employee engagement posit that this could be due to a lack of consistent conceptualization of the phenomenon.
           This qualitative descriptive study was conducted to understand the perceived attitudes and behaviors of the nurses who are engaged in their work from the perspective of both their peers and leaders.  Sixteen total participants were interviewed utilizing a semi-structured interview guide with questions that were derived from Arnold Bakker’s evidence-based model of work engagement.  Content analysis was utilized to identify themes and sub-themes from each of the participant group’s responses to each of the questions.  There were minimal differences in the responses of the direct-care RNs as compared to the nurse leaders regarding their perceptions of the engaged nurse.  Resulting themes were then synthesized and four overarching themes identified. Overarching themes were personal style, extra-role behavior, commitment to the patient, and leadership.
           Participant responses supported Bakker’s model, but highlighted the engaged nurse’s personality as a significant and widely overlooked contributor to engagement.  By recognizing the personal attributes inherent to the engaged nurse hospitals may better understand the traits important to the recruitment of nurses who are more likely to be engaged in their work.  Effective recruitment and retention of a highly engaged workforce will allow organizations to benefit from the extra-role work often demonstrated by the engaged nurse and realize improved patient outcomes as a result.

description: The envelope of the red supergiant VY CMa has long been considered an extreme example of episodic mass loss that is possibly taking place in other cool and massive evolved stars. Recent submm observations of the envelope revealed massive dusty clumps within 800 mas from the star which reinforce the picture of drastic mass-loss phenomena in VY CMa. We present new ALMA observations at an angular resolution of 0.1" and at an unprecedented sensitivity that reveal further details about the dusty clumps. We resolve more discrete features and identify a submm counterpart of a more distant Clump SW known from visual observations. The brightest clump, named C, is resolved in the observations. Gas seen against the resolved continuum emission of clump C produces a molecular spectrum in absorption. Except for SW Clump, no molecular emission is found to be associated with the dusty clumps and we propose that the dusty structures have an atypically low gas content. We attempt to reproduce the properties of the dusty clumps through three-dimensional radiative-transfer modeling. Although a clump configuration explaining the observations is found, it is not unique. A very high optical depth of all clumps to the stellar radiation make the modeling very challenging and requires unrealistically high dust masses. It is suggested that the dusty features have substructures, e.g. porosity, that allows deeper penetration of stellar photons within the clumps than in a homogeneous configuration. A comparison of the estimated clumps ages to variations in the stellar visual flux for over a century suggests that the mechanism responsible for their formation is not uniquely manifested by enhanced or strongly diminished visual light. The study demonstrates that the dusty mass-loss episodes of VY CMa are indeed unparalleled among all known non-explosive stars. The origin of these episodes remains an unsolved problem.

description: Despite progress made over the past decade, women in medicine are underrepresented in advanced academic leadership positions. This qualitative case study explored the perceptions of full-time women faculty at one large urban academic medical center regarding leadership trajectories within academic medicine, comparing those who are and those who are not in institutionally-defined leadership roles. The purpose of the research was to explore participants’ perceptions of the characteristics of effective leadership, how they view their own leadership potential, what motivates them to (or not to) seek leadership positions, what facilitators and challenges they may face in seeking such positions, what rewards and sacrifices they may have experienced on their career paths, and how and what they learned in the process. In-depth, semi-structured interviews were conducted with 27 full-time women faculty members of one large urban academic medical center. The participants were recruited based on leadership positions, years in practice and specialties. Several key findings emerged from the interviews. First, all participants described interpersonal skills as important elements of effective leadership in academic medicine. Second, women described gender biases in the workplace as challenges on their career paths. Also, work-life balance and the unique demands placed on working mothers were discussed. Third, mentoring relationships were perceived as facilitators of career advancement. Also, a majority of participants described having an interest in and self-efficacy toward leadership. Fourth, women described focusing their learning on acquiring organizational and administrative skills, through a combination of informal and formal learning. Most of the learning described was incidental and unplanned. Experiences were important for the incremental development of leadership proficiency. Women engaged in reflection to improve performance and to evaluate self. The benefits of engaging in communities of practice were described.
Use of locally sourced moss, lichen and vascular plant propagules for the revegetation of mineral disturbances in a boreal climate

description: Mosses, lichens and low ericaceous shrubs are the dominant component of the barrens vegetation around Mary’s Harbour, Labrador. In 2004, an experiment was undertaken near this town where propagules (fragments, seeds, spores, etc.) of mosses, lichens and vascular plants, obtained from nearby donor sites, were spread thinly onto experimental plots that were set up on four disturbed, bare mineral soil areas. The plots were covered with grass mulch, and low doses of bone meal fertilizer were applied. Reintroduction plots were compared to control plots in order to see if reintroducing local plants propagules accelerates the recovery of vegetation. Data collected after one, two and five years showed that vegetation establishment was better on plots where propagules were introduced than on control plots. Five years after the onset of the experiment, mosses (mainly Polytrichaceae), fruticose and foliose lichens and seedlings of ericaceous shrubs and other woody species were well established on the plots where plant material had been spread. Control plots, in contrast, had a lower moss cover, fewer shrubs and seedlings, and generally lacked lichens.

The aim of this thesis is to explore new methods and tools, from both algorithmic and analytical perspectives, that are useful to solve such problems.
In Chapter 1 and 2, we introduce some techniques of asymptotic analysis that are relatively new to queueing applications in order to give more accurate probabilistic characterization of queueing models with large scale and complicated structure. In particular, Chapter 1 gives the first functional large deviation result for infinite-server system with general inter-arrival and service times. The functional approach we use enables a nice description of the whole system over the entire time horizon of interest, which is important in real problems. In Chapter 2, we construct a queueing model for the so-called limit order book that is used in main financial markets worldwide. We use an asymptotic approach called multi-scale modeling to disentangle the complicated dependence among the elements in the trading system and to reduce the model dimensionality. The asymptotic regime we use is inspired by empirical observations and the resulting limit process explains and reproduces stylized features of real market data. Chapter 2 also provides a nice example of novel applications of queueing models in systems, such as the electronic trading system, that are traditionally outside the scope of queueing theory.
Chapter 3 and 4 focus on stochastic simulation methods for performance evaluation of queueing models where analytic approaches fail.
In Chapter 3, we develop a perfect sampling algorithm to generate exact samples from the stationary distribution of stochastic fluid networks in polynomial time. Our approach can be used for time-varying networks with general inter-arrival and service times, whose stationary distributions have no analytic expression. In Chapter 4, we focus on the stochastic systems with continuous random fluctuations, for instance, the workload arrives to the system in continuous flow like a Levy process. We develop a general framework of simulation algorithms featuring a deterministic error bound and an almost square root convergence rate. As an application, we apply this framework to estimate the stationary distributions of reflected Brownian motions and the performance of our algorithm is better than existing prevalent numeric methods.

description: The presence of dark matter substructure will boost the signatures of dark matter annihilation. We review recent progress on estimates of this subhalo boost factor---a ratio of the luminosity from annihilation in the subhalos to that originating the smooth component---based on both numerical $N$-body simulations and semi-analytic modelings. Since subhalos of all the scales, ranging from the Earth mass (as expected, e.g., the supersymmetric neutralino, a prime candidate for cold dark matter) to galaxies or larger, give substantial contribution to the annihilation rate, it is essential to understand subhalo properties over a large dynamic range of more than twenty orders of magnitude in masses. Even though numerical simulations give the most accurate assessment in resolved regimes, extrapolating the subhalo properties down in sub-grid scales comes with great uncertainties---a straightforward extrapolation yields a very large amount of the subhalo boost factor of $\gtrsim$100 for galaxy-size halos. Physically motivated theoretical models based on analytic prescriptions such as the extended Press-Schechter formalism and tidal stripping modeling, which are well tested against the simulation results, predict a more modest boost of order unity for the galaxy-size halos. Giving an accurate assessment of the boost factor is essential for indirect dark matter searches and thus, having models calibrated at large ranges of host masses and redshifts, is strongly urged upon.

description: Lexical tones have presented great difficulties for second language learners whose native language is non-tonal. A number of recent studies suggest categorical-like perception of lexical tones by native Mandarin speakers. Can native speakers of non-tonal languages acquire categorical representations of lexical tones? Are there any differences between L1 and L2 tone perceptions? This study investigates brain responses to lexical tone categorization for three groups of adult listeners: 1) native English speakers who had no exposure to Mandarin before age 17, but took advanced Mandarin courses as adults; 2) naïve English speakers; and 3) native Mandarin speakers. Two tonal continua were derived from natural speech through interpolation within two tonal contrasts (Tone 1/Tone 4; Tone 2/Tone 3).  Firstly, category boundaries were examined through classic identification and discrimination tasks. Secondly, high-density electroencephalography (EEG) was used to record brain responses while participants listened to tones in two oddball paradigms: across-category and within-category. If perception of lexical tones is categorical, cross-category deviants are expected to elicit larger ERP responses (specifically, mismatch negativity (MMN) and P300) than within-category deviants. Both behavioral and ERP results indicate that lexical tones are perceived categorically by native Chinese speakers but not by inexperienced English speakers. Although English learners of Chinese demonstrated categorical perception in behavioral tasks, their ERP response did not differ between within- and across-category conditions, however, significantly greater P300 responses were observed. Acoustic cues and characteristics of L2 phonological learning in adulthood are discussed.

Delocalization of Wannier-Stark ladders by phonons: tunneling and stretched polarons

description: We study the coherent dynamics of a Holstein polaron in strong electric fields. A detailed analytical and numerical analysis shows that even for small hopping constant and weak electron-phonon interaction, polaron states can become delocalized if a resonance condition develops between the original Wannier-Stark states and the phonon modes, yielding both tunneling and `stretched' polarons. The unusual stretched polarons are characterized by a phonon cloud that {\em trails} the electron, instead of accompanying it. In general, our novel approach allows us to show that the polaron spectrum has a complex nearly-fractal structure, due to the coherent coupling between states in the Cayley tree which describes the relevant Hilbert space. The eigenstates of a finite ladder are analyzed in terms of the observable tunneling and optical properties of the system.

Perfect Simulation and Deployment Strategies for Detection

Publisher: name: Columbia University
Year: 2015
Subjects: Operations research

description: This dissertation contains two parts. The first part provides the first algorithm that, under minimal assumptions, allows to simulate the stationary waiting-time sequence of a single-server queue backwards in time, jointly with the input processes of the queue
      (inter-arrival and service times).
      The single-server queue is useful in applications of DCFTP (Dominated Coupling From The Past), which is a well known protocol for simulation without bias from steady-state distributions. Our algorithm terminates in finite time assuming only finite mean of the
      inter-arrival and service times. In order to simulate the single-server queue in stationarity until the first idle period in finite expected termination time we require the existence of finite variance. This requirement is also necessary for such idle time (which is a natural
      coalescence time in DCFTP applications) to have finite mean. Thus, in this sense, our algorithm is applicable under minimal assumptions.
      The second part studies the behavior of diffusion processes in a random environment.
      We consider an adversary that moves in a given domain and our goal is to produce an optimal  strategy to detect and neutralize  him by a given deadline. We assume that the target's dynamics follows a diffusion process whose parameters are informed by available intelligence information. We will dedicate one chapter to the rigorous formulation of the detection problem, an introduction of several frameworks that can be considered when applying our methods, and a discussion on the challenges of finding the analytical optimal solution. Then, in the following  chapter, we will present our main result, a large deviation behavior of the adversary's survival probability under a given strategy. This result will be later give rise to asymptotically efficient Monte Carlo algorithms.

description: We derive a closed formula for the matrix elements of the volume operator for canonical Lorentzian quantum gravity in four spacetime dimensions in the continuum in a spin-network basis. We also display a new technique of regularization which is state dependent but we are forced to it in order to maintain diffeomorphism covariance and in that sense it is natural. We arrive naturally at the expression for the volume operator as defined by Ashtekar and Lewandowski up to a state independent factor.

description: We study the distribution of the interstellar neutral (ISN) gas density and the pick-up ion (PUI) density of hydrogen, helium, neon, and oxygen in the heliosphere for heliocentric distances from inside 1 au up to the solar wind termination shock (TS), both in and out of the ecliptic plane. We discuss similarities and differences in the large-scale structures of the ISN gas and PUIs formed in the heliosphere between various species. We discuss the distribution of ISN gas and PUI densities for two extreme phases of the solar activity cycle, it is the solar minimum and the solar maximum. We identify the location of the ISN gas density cavity of various species. We study the relative abundance ratios of Ne/O, H/He, Ne/He, and O/He for ISN gas and PUIs densities and their variation with location in the heliosphere. We also discuss the modulation of relative abundance ratios of ISN gas and PUIs along the TS. We conclude that the preferable locations for detection of He$^+$ and Ne$^+$ PUIs are in the downwind hemisphere within 1~au, whereas for H$^+$ and O$^+$ PUIs the preferable locations for detection are for distances from Jupiter to Pluto orbits.
