description: We develop a method in which the electronic densities of small fragments determined by Kohn-Sham density functional theory (DFT) are embedded using stochastic DFT to form the exact density of the full system. The new method preserves the scaling and the simplicity of the stochastic DFT but cures the slow convergence that occurs when weakly coupled subsystems are treated. It overcomes the spurious charge fluctuations that impair the applications of the original stochastic DFT approach. We demonstrate the new approach on a fullerene dimer and on clusters of water molecules and show that the density of states and the total energy can be accurately described with a relatively small number of stochastic orbitals.

description: We define a new topological invariant of line arrangements in the complex projective plane. This invariant is a root of unity defined under some combinatorial restrictions for arrangements endowed with some special torsion character on the fundamental group of their complements. It is derived from the peripheral structure on the group induced by the inclusion map of the boundary of a tubular neigborhood in the exterior of the arrangement. By similarity with knot theory, it can be viewed as an analogue of linking numbers. This is an orientation-preserving invariant for ordered arrangements. We give an explicit method to compute the invariant from the equations of the arrangement, by using wiring diagrams introduced by Arvola, that encode the braid monodromy. Moreover, this invariant is a crucial ingredient to compute the depth of a character satisfying some resonant conditions, and complete the existent methods by Libgober and the first author. Finally, we compute the invariant for extended MacLane arrangements with an additional line and observe that it takes different values for the deformation classes.

Assessing Cervical Dislocation as a Humane Euthanasia Method in Mice
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Research investigators often choose to euthanize mice by cervical dislocation (CD) when other methods would interfere with the aims of a research project. Others choose CD to assure death in mice treated with injected or inhaled euthanasia agents. CD was first approved for mouse euthanasia in 1972 by the AVMA Panel on Euthanasia, although scientific assessment of its humaneness has been sparse. Here we compared 4 methods of spinal dislocation–3 targeting the cervical area (CD) and one the thoracic region–in regard to time to respiratory arrest in anesthetized mice. Of the 81 mice that underwent CD by 1 of the 3 methods tested, 17 (21%) continued to breathe, and euthanasia was scored as unsuccessful. Postmortem radiography revealed cervical spinal lesions in 5 of the 17 cases of unsuccessful CD euthanasia. In addition, 63 of the 64 successfully euthanized mice had radiographically visible lesions in the high cervical or atlantooccipital region. In addition, 50 of 64 (78%) mice euthanized successfully had radiographically visible thoracic or lumbar lesions or both. Intentionally creating a midthoracic dislocation in anesthetized mice failed to induce respiratory arrest and death in any of the 18 mice subjected to that procedure. We conclude that CD of mice holds the potential for unsuccessful euthanasia, that anesthesia could be valuable for CD skills training and assessment, and that postmortem radiography has minimal promise in quality-control assessments.

description: In order to study the phase diagram from a microscopic viewpoint, we have measured wTF- and ZF-$μ^+$SR spectra for the Sr$_{1-x}$Ca$_x$Co$_2$P$_2$ powder samples with $x=0$, 0.2, 0.4, 0.5, 0.6, 0.8, and 1. Due to a characteristic time window and spatial resolution of $μ^+$SR, the obtained phase diagram was found to be rather different from that determined by magnetization measurements. That is, as $x$ increases from 0, a Pauli-paramagnetic phase is observed even at the lowest $T$ measured (1.8~K) until $x=0.4$, then, a spin-glass like phase appears at $0.5\leq x\leq0.6$, and then, a phase with wide field distribution probably due to incommensurate AF order is detected for $x=0.8$, and finally, a commensurate $A$-type AF ordered phase (for $x=1$) is stabilized below $T_{\rm N}\sim80~$K. Such change is most likely reasonable and connected to the shrink of the $c$-axis length with $x$, which naturally enhances the magnetic interaction between the two adjacent Co planes.

Exploring climate change adaptation in the Mongolian steppes using an Ecosystem Services approach

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: In dryland regions of the world, the risks from climate change of severe impacts on pastureland ecosystems, and local livelihoods dependent on them, are high. Improving climate change adaptation to support local livelihoods and sustain natural ecosystems in these regions is needed. The Mongolian steppes are a substantial dryland region that is experiencing faster climate change than most other regions of the world. This thesis explores climate adaptation challenges and opportunities in the pasturelands of the northeast Mongolian steppes, where nomadic herding is the predominant use of the landscape. In the process, it investigates ways in which ecosystem services approaches can contribute to local environmental decision-making in rural areas in developing economies. A mixed methods approach, consisting of in-depth interviews with nomadic herders and with key informants from the local municipalities and natural resources management organisations, focus group discussions, a survey of nomadic herder households, and a policy workshop in the national capital, were used to investigate climate change impacts on local livelihoods and pastureland ecosystem services. The study explores herders’ experience of climate change impacts on key ecosystem services: changing water availability, changing quantity and quality of pasture, and livelihoods changing as a result. The study shows that traditional knowledge has and is continuing to play a key role in adapting to environmental variability - traditional herd management practices, collective institutions, and mobility strategies all contribute substantially. However, nomadic communities are facing unprecedented climate risks that threaten their livelihoods. Possibilities for future adaptation are explored. The study found that the traditional understanding of the relationship between nomads and the pasturelands, which is governed by “baigaliin khishig”- commitment to benefiting from nature without altering its structure - resonates with western ecosystem services thinking. This study highlights that an ecosystem services approach can contribute to local environmental management in ways that support climate change adaptation, if it leverages traditional ecosystem services thinking. The research adds significantly to the ecosystem services literature by contributing a local, rural, developing world case study from the drylands.

description: The emergency department (ED) is a critical setting for the treatment of patients with opioid misuse. Detecting relevant clinical profiles allows for tailored treatment approaches. We sought to identify and characterize subphenotypes of ED patients with opioid-related encounters. A latent class analysis was conducted using 14,057,302 opioid-related encounters from 2016 through 2017 using the National Emergency Department Sample (NEDS), the largest all-payer ED database in the United States. The optimal model was determined by face validity and information criteria-based metrics. A three-step approach assessed class structure, assigned individuals to classes, and examined characteristics between classes. Class associations were determined for hospitalization, in-hospital death, and ED charges. The final five-class model consisted of the following subphenotypes: Chronic pain (class 1); Alcohol use (class 2); Depression and pain (class 3); Psychosis, liver disease, and polysubstance use (class 4); and Pregnancy (class 5). Using class 1 as the reference, the greatest odds for hospitalization occurred in classes 3 and 4 (Ors 5.24 and 5.33, p < 0.001) and for in-hospital death in class 4 (OR 3.44, p < 0.001). Median ED charges ranged from USD 2177 (class 1) to USD 2881 (class 4). These subphenotypes provide a basis for examining patient-tailored approaches for this patient population.

description: We study the effects of irradiating water with 3 MeV protons at high doses by observing the motion of charged polystyrene beads outside the proton beam. By single-particle tracking, we measure a radial velocity of the order of microns per second. Combining electrokinetic theory with simulations of the beam-generated reaction products and their outward diffusion, we find that the bead motion is due to electrophoresis in the electric field induced by the mobility contrast of cations and anions. This work sheds light on the perturbation of biological systems by high-dose radiations and paves the way for the manipulation of colloid or macromolecular dispersions by radiation-induced diffusiophoresis.
The Medical Home: Locus of Physician Formation

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Family medicine is currently undergoing a transformation and, amid such change, the medical home has emerged as the new polestar. This article examines the medical home through the lens of philosopher Alasdair MacIntyre and offers a perspective, informed by Hubert Dreyfus and Peter Senge, about medical homes as practical sites of formation for family physicians. The intellectual past of family medicine points to contextually sensitive patient care as a practice that is particular to the discipline, with the virtue of “placing patients within contexts over time” as a commonly held virtue. Dreyfus provides a model of knowledge and skill acquisition that is relevant to the training of family physicians in practical wisdom. In this model, there is a continuum from novice to more advanced stages of professional formation that is aided by rules that not only must be learned, but must be applied in greater contextually informed situations. Senge’s emphasis on learning organizations— organizations where people are continually learning how to learn together—presents a framework for evaluating the extent to which future medical homes facilitate or retard the formation of family physicians.

description: We investigate the timescales of evolution of stellar coronae in response to surface differential rotation and diffusion. To quantify this we study both the formation time and lifetime of a magnetic flux rope in a decaying bipolar active region. We apply a magnetic flux transport model to prescribe the evolution of the stellar photospheric field, and use this to drive the evolution of the coronal magnetic field via a magnetofrictional technique. Increasing the differential rotation (i.e. decreasing the equator-pole lap time) decreases the flux rope formation time. We find that the formation time is dependent upon the geometric mean of the lap time and the surface diffusion timescale. In contrast, the lifetime of flux ropes are proportional to the lap time. With this, flux ropes on stars with a differential rotation of more than eight times the solar value have a lifetime of less than two days. As a consequence, we propose that features such as solar-like quiescent prominences may not be easily observable on such stars, as the lifetimes of the flux ropes which host the cool plasma are very short. We conclude that such high differential rotation stars may have very dynamical coronae.

description: The derivation of a quantum Markovian model for an opto-mechanical system consisting of a quantum mechanical mirror interacting with quantum optical input fields via radiation pressure is difficult problem which ultimately involves the scattering process of quantum stochastic calculus. We show that while the scattering process may be approximated in a singular limit by regular processes using different schemes, however the limit model is highly sensitive to how the approximation scheme is interpreted mathematically. We find two main types of stochastic limits of regular models, and illustrate the origin of this difference at the level of one particle scattering. As an alternative modelling scheme, we consider models of mirrors as non-trivial dielectric medium with a boundary that is itself quantized. Rather than treating the plane waves for the electromagnetic field, we take the actual physical modes and quantize these. The input-output formalism is then obtained in the far zone where the plane wave approximation is valid. Several examples are considered, and the quantum stochastic model is derived. We also consider the quantum trajectories problem for continual measurement of the reflect output fields, and derive the stochastic master equations for homodyning and photon counting detection to estimate the mirror observables.

description: BACKGROUND: the clinical utility of the prehypertension label is questionable. We sought to estimate how often patients with prehypertension are being told about it by their primary care clinicians.

METHODS: we conducted a cross-sectional study of adult patients visiting practices within the North Carolina Family Medicine Research Network in summer 2008. Non-hypertensive patients were asked whether a doctor or other health care provider had ever told them they had "prehypertension"; a subsample of patients with measured blood pressure (BP) in the prehypertension range was asked the same question.

RESULTS: of 1008 non-hypertensive patients, 1.9% indicated being told they had prehypertension. Among a subsample of 102 patients with measured BP in the prehypertension range, 2.0% indicated being told they had prehypertension.

CONCLUSION: few patients who probably have prehypertension are being told about it by clinicians.

description: A highly stereoselective synthesis of 11-acetoxy-4-deoxyasbestinin D (1) has been completed in 26 linear steps. The synthesis hinges on a selective glycolate aldol addition to establish the C-2 stereocenter, a ring-closing metathesis reaction to complete the oxonene, and an intramolecular Diels-Alder cycloaddition to establish the relative configuration at C-1, C-10, and C14. This initial total synthesis of an asbestinin also serves to confirm the absolute configuration of this sub-class of the C2-C11-cyclized cembranoid natural products.

description: BACKGROUND AND AIM: There is no gold-standard and considerable heterogeneity in outcome measures used to evaluate treatments for opioid use disorder (OUD) along the opioid treatment cascade. The aim of this study was to develop the US National Institute on Drug Abuse (NIDA) National Drug Abuse Treatment Clinical Trials Network (CTN) opioid use disorder core outcomes set (OUD-COS). DESIGN: Four-round, e-Delphi expert panel consensus study and plenary research group discussion and targeted consultation. SETTING: United States. PARTICIPANTS: A panel of 25 members including clinical practitioners, clinical researchers and administrative staff from the CTN, the network's affiliated clinical and community sites and the NIDA Centre for the CTN. MEASUREMENTS: From a pool of 24 candidate items in four domains (biomedical/disease status; behaviors, symptoms and functioning; opioid treatment cascade; and morbidity and mortality), the panel completed an on-line questionnaire to rank items with defined specification on a 9-point scale for importance, with a standard 70% consensus criterion. FINDINGS: After the fourth round of the questionnaire and subsequent discussion, consensus was reached for five outcomes: two patient-reported (global impression of improvement and incident non-fatal overdose); one clinician-reported (illicit/non-medical drug toxicology); and two from administrative records (duration of treatment and fatal opioid poisoning). CONCLUSIONS: An e-Delphi consensus study has produced the US National Institute on Drug Abuse (NIDA) National Drug Abuse Treatment Clinical Trials Network opioid use disorder core outcomes set (version 1) for opioid use disorder treatment efficacy and effectiveness research.

We consider an initial minimum-uncertainty Gaussian wave-packet, and find that its long term dynamics displays the universal phenomena of spontaneous collapse and quantum revival. We estimate the timescales associated with these phenomena based on very general arguments for various materials, whose carrier dynamics is described either by the Schrödinger equation or by the Dirac equation.

description: A single-pot three-component coupling reaction of silylglyoxylates (1), terminal alkynes, and aldehydes in the presence of ZnI2 and Et3N is presented. The products of the reaction, densely functionalized silyl-protected glycolate aldols (2), can be converted to the corresponding acetonides (3) in a one-pot deprotection/ketalization sequence. A variety of terminal alkynes and aldehydes can be successfully employed to give a range of highly functionalized, fully protected 1,2-diols in good yields and moderate diastereoselectivities. Mechanistic experiments suggest that the zinc acetylide reacts with the silylgyloxylate (1) in a chemoselective manner. Using an unoptimized (+)-N-methylephedrine and Zn(OTf)2 system, silyl-deprotected adduct 2 was formed in 64% ee and 89:11 dr.

description: A general strategy for the rapid structural analysis of DNA binding ligands is described as it was applied to the study of RT29, a new benzimidazole-diamidine compound containing a highly twisted diphenyl ether linkage. By combining the existing high-throughput fluorescent intercalator displacement (HT-FID) assay developed by Boger et al. and a high-resolution (HR) host-guest crystallographic technique, a system was produced that was capable of determining detailed structural information pertaining to RT29-DNA interactions within ~ 3 days. Our application of the HT-HR strategy immediately revealed that RT29 has a preference for four-base pair, A/T-rich sites (AATT) and a similar tolerance and affinity for three A·T-base pair sites (such as ATTC) containing a G·C base pair. Based on these selectivities, oligonucleotides were designed and the host-guest crystallographic method was used to generate diffraction quality crystals. Analysis of the resulting crystal structures revealed that the diphenyl ether moiety of RT29 undergoes conformational changes that allow it to adopt a crescent shape that now complements the minor groove structure. The presence of a G·C base pair in the RT29 binding site of ATTC did not overly perturb its interaction with DNA - the compound adjusted to the nucleobases that were available through water-mediated interactions. Our analyses suggest that the HT-HR strategy may be used to expedite the screening of novel minor groove binding compounds leading to a direct, HR structural determination.

description: Collaboration among researchers is an essential component of the modern scientific enterprise, playing a particularly important role in multidisciplinary research. However, we continue to wrestle with allocating credit to the coauthors of publications with multiple authors, since the relative contribution of each author is difficult to determine. At the same time, the scientific community runs an informal field-dependent credit allocation process that assigns credit in a collective fashion to each work. Here we develop a credit allocation algorithm that captures the coauthors' contribution to a publication as perceived by the scientific community, reproducing the informal collective credit allocation of science. We validate the method by identifying the authors of Nobel-winning papers that are credited for the discovery, independent of their positions in the author list. The method can also compare the relative impact of researchers working in the same field, even if they did not publish together. The ability to accurately measure the relative credit of researchers could affect many aspects of credit allocation in science, potentially impacting hiring, funding, and promotion decisions.

Gender-based Systematics in HST Proposal Selection

description: Proposal success rates are calculated for HST Cycles 11 through 21 as a function of the gender of the Principal Investigator (PI). In each cycle, proposals with male PIs have a higher success rate, with the disparity greatest for Cycles 12 and 18. The offsets are small enough that they might be ascribed to chance for any single cycle, but the consistent pattern suggests the presence of a systematic effect. Closer inspection of results from Cycles 19, 20 and 21 shows that the systematic difference does not appear to depend on the geographic origin of the proposal nor does it depend on the gender distribution on the review panels. Segregating proposals by the seniority of the PI, the success rates by gender for more recent graduates (Ph.d. since 2000) are more closely comparable. There is also a correlation between success by gender and the average seniority of the review panel for Cycles 19 and 20, but not Cycle 21. We discuss these results and some consequent changes to the proposal format and additions to the HST TAC orientation process.

description: The evolution of global binary black holes variables such as energy or linear momentum are mainly obtained by applying numerical methods near coalescence, post-Newtonian (PN) expansions, or a combination of both. In this paper, we use a fully relativistic formalism presented several years ago that only uses global variables defined at null infinity together with the gravitational radiation emitted by the source to obtain the time evolution of such variables for binary black holes (BBH) systems. For that, we use the Rochester catalog composed of 776 BBHs simulations. We compute the final velocity, radiated energy, and intrinsic angular momentum predicted by the dynamical equations in this formalism for nonspinning, aligned and antialigned spins, and several different precessing configurations. We compare obtained values with reported values in numerical simulations. As BBHs parameter space is still not completely covered by numerical simulations, we fit phenomenological formulas for practical applications to the radiated energy and final velocities obtained. Also, we compare the fits with reported values. In conclusion, we see that our formulae and correlations for the variables described in this work are consistent with those found in the general literature.

description: The electronic properties of graphene are described by a Dirac Hamiltonian with a fourfold symmetry of spin and valley. This symmetry may yield novel fractional quantum Hall (FQH) states at high magnetic field depending on the relative strength of symmetry breaking interactions. However, observing such states in transport remains challenging in graphene, as they are easily destroyed by disorder. In this work, we observe in the first two Landau levels (v<6) the composite-fermion sequences of FQH states at p/(2p+1) between each integer filling factor. In particular, odd numerator fractions appear between v=1 and v=2, suggesting a broken valley symmetry, consistent with our observation of a gap at charge neutrality and zero field. Contrary to our expectations, the evolution of gaps in a parallel magnetic field suggests that states in the first Landau level are not spin-polarized even up to very large out of plane fields.
Enantioselective Total Synthesis of FD-891

Year: 2006

description: The enantioselective synthesis of FD-891 has been achieved with a longest linear sequence of 21 steps. The synthetic strategy involves the use of aldol additions of a chlorotitanium enolate of N-acylthiazolidinethiones as the key reaction to establish 6 of the 10 stereogenic centers. A key cross-metathesis and a late-stage Julia olefination serve to assemble three key subunits.

description: Mental health concerns have been well studied among youth experiencing homelessness, yet few studies have explored factors that contribute to well-being in this population. The current cross-sectional study examined rates and correlates of well-being among youth experiencing homelessness. This is a descriptive, secondary analysis of the baseline data from a clinical intervention study. Ninety-nine youth (aged 16-25) who were experiencing homelessness were recruited in Chicago. Approximately 40% of the sample reported average or above average well-being relative to existing benchmarks. Having medical insurance, a mobile phone, and a history of more severe childhood trauma were unique cross-sectional predictors of worse well-being (all ps < 0.034). A significant portion of our sample experienced well-being. Having access to certain resources may be counterintuitive indicators of poorer well-being among youth experiencing homelessness, perhaps because they are indicators of greater need or increased social comparison among these youth.

description: The reactivity of iron atoms, clusters and nanoparticles (nZVI) is of increasing interest owing to their important practical applications, ranging from the steel industry to water remediation technologies. Here, we provide an overview of computational methods and models that can be applied to study nZVI reactions and discuss their benefits and limitations. We also report current progress in calculations through recent examples treating the reactivity of nZVI particles. Finally, we consider the potential use of highly accurate methods with favorable scaling (such as quantum Monte Carlo or random phase approximation), which are currently considered too computationally expensive but are expected to become more amenable in the future as computer power increases.

description: We present the results of an experimental study of pattern formation in horizontally oscillating granular suspensions. Starting from a homogeneous state, the suspension turns into a striped pattern within a specific range of frequencies and amplitudes of oscillation. We observe an initial development of layered structures perpendicular to the vibration direction and a gradual coarsening of the stripes. However, both processes gradually slow down and eventually saturate. The probability distribution of the stripe width approaches a nonmonotonic steady-state form which can be approximated by a Poisson distribution. We observe similar structures in MD simulations of soft spherical particles coupled to the motion of the surrounding fluid.

description: The l-menthone-derived TADDOL phosphite 6b catalyzes highly enantioselective conjugate additions of acyl silanes to α,β-unsaturated amides. p-Methoxybenzoyl cyclohexyldimethylsilane adds to a variety of N,N-dimethyl acrylamide derivatives in the presence of the lithium salt of 6b. In many instances the α-silyl-γ-ketoamide product undergoes facile enantioenrichment (to 97–99% ee) upon recrystallization. Desilylation with HF·pyr affords the formal Stetter addition products. Baeyer–Villiger oxidation of the desilylated γ-ketoamides affords useful ester products. An X-ray diffraction study of 6b reveals that the isopropyl group of the menthone ketal influences the position of the syn-pseudoaxial phenyl group in the TADDOL structure. Through a crossover experiment, the silicon migration step in the reaction mechanism is shown to be strictly intramolecular.
