description: Measurements of the transverse Hall resistance are widely used to investigate electron transport, magnetization phenomena, and topological quantum states. Owing to the difficulty of probing transient changes of the transverse resistance, the vast majority of Hall effect experiments are carried out in stationary conditions using either dc or ac currents. Here we present an approach to perform time-resolved measurements of the transient Hall resistance during current-pulse injection with sub-nanosecond temporal resolution. We apply this technique to investigate in real-time the magnetization reversal caused by spin-orbit torques in ferrimagnetic GdFeCo dots. Single-shot Hall effect measurements show that the current-induced switching of GdFeCo is widely distributed in time and characterized by significant activation delays, which limit the total switching speed despite the high domain-wall velocity typical of ferrimagnets. Our method applies to a broad range of current-induced phenomena and can be combined with non-electrical excitations to perform pump-probe Hall effect measurements.

description: We consider two conformal defects close to each other in a free theory, and study what happens as the distance between them goes to zero. This limit is the same as zooming out, and the two defects have fused to another defect. As we zoom in we find a non-conformal effective action for the fused defect. Among other things this means that we cannot in general decompose the two-point correlator of two defects in terms of other conformal defects. We prove the fusion using the path integral formalism by treating the defects as sources for a scalar in the bulk.

description: Synthetic cannabinoid metabolites with a 5F-4OH pentyl side chain are of great interest, and several synthetic methods have been developed for the synthesis of these types of metabolites in the literature, which is either lengthy or inappropriate for upscaling. Herein, a straightforward method has been developed and reported for the synthesis of a key intermediate in four steps with an overall yield of 49% on a multigram scale, and its application in the synthesis of nine potential metabolites of synthetic cannabinoids with a 5F-4OH pentyl side chain.

description: We present an occultation of the central X-ray emitting region in the Seyfert Galaxy NGC 1365. This extreme spectral variation (from Compton-thin to reflection-dominated and back to Compton-thin in four days) has been caught in a ten days Chandra monitoring campaign consisting of six short (15 ks) observations performed every two days. We discuss the implications of this occultation within the scenario of a Compton-thick cloud crossing the line of sight of the X-ray source. We estimate a source size R<10^14 cm and a distance of the cloud from the source D<10^16 cm. This direct measurement confirms the theoretical expectations of an extremely compact X-ray source, and shows that the Compton-thick circumnuclear gas is located at a distance from the center on the scale of the Broad Line Region.

Children's pain on the first post-operative day
Creators: name: Miller, Lori-Mae
Publisher: name: University of British Columbia
Year: 2010

description: A review of the literature identified that few research studies have been published which examined the post-operative pain of children, particularly those between the ages of 4 and 7 years. As a result, theoretical literature has been the major contributor to the understanding of the concept of children's post-operative pain. Therefore, the purpose of this study was to describe the post-operative pain of hospitalized children aged 4 to 7 years on the first postoperative day, through a self-reported measure of pain intensity levels as well as descriptions of the children's overt behaviours used to express pain. Data were gathered on the pain intensity levels (using the PCT) and overt behaviours of 11 children between the ages of 4 and 8 years on the first post-operative day between the hours of 0800 and 2000. In addition, data regarding parental presence and the administration of analgesics were also collected for these children. Findings related to pain intensity scores provided the basis for three important conclusions. First, all of the children were able to place a value on their pain using the PCT. Second, all of the children were experiencing some degree of post-operative pain possibly related to the lack of consistent administration of analgesia. Third, parental presence did not influence the pain intensity scores reported by the children. Findings related to the overt behaviours exhibited by children also provided the basis for three important conclusions. First, the most frequent behaviours identified were not those normally associated with feelings of pain. The researcher believed that this lack of expected response was as a result of the children's ability to adapt and cope with the pain. Second, behavioural measurement of pain may not be a reliable and valid measure of post-operative pain. Third, parental presence or absence did not influence the overt behaviours exhibited.

description: Owing to recent advances in laser technology, it has become important to investigate fundamental laser-assisted processes in very powerful laser fields. In the present work and within the framework of laser-assisted quantum electrodynamics (QED), electron-proton scattering was considered in the presence of a strong electromagnetic field of circular polarization. First, we present a study of the process where we only take into account the relativistic dressing of the electron without the proton. Then, in order to explore the effect of the proton dressing, we fully consider the relativistic dressing of the electron and the proton together and describe them by using Dirac-Volkov functions. The analytical expression for the differential cross section (DCS) in both cases is derived at lowest-order of perturbation theory. As a result, the DCS is notably reduced by the laser field. It is found that the effect of proton dressing begins to appear at laser field strengths greater than or equal to $10^{10}~\text{V/cm}$ and it therefore must be taken into account. The influence of the laser field strength and frequency on the DCS is reported. A comparison with the Mott scattering and the laser-free results is also included.

description: An unprecedented method for the synthesis of 2-(prop-2-yn-1-ylidene)-2,3-dihydro-1,4-thiazepines from N-(2,4-pentadiynyl) β-enaminones is reported. Upon treatment with Lawesson’s reagent, N-(2,4-pentadiynyl) β-enaminones were thionated to furnish N-(2,4-pentadiynyl) β-enaminothiones, which immediately underwent 7-exo-dig cyclization to generate 2-(prop-2-yn-1-ylidene)-2,3-dihydro-1,4-thiazepines in one-pot. A general trend was observed for various N-(2,4-pentadiynyl) β-enaminones and cyclization proceeded with broad functional group tolerance. This operationally easy method may provide quick access to a library of functionalized 1,4-thiazepines in the field of pharmaceutical chemistry.

description: We present Keck laser guide star observations of two T2.5 dwarfs - 2MASS J11061197+2754225 & 2MASS J14044941-3159329 - using NIRC2 on Keck-II and find 2MASS J14044941-3159329 to be a 0.13" binary. This system has a secondary that is 0.45 mags brighter than the primary in J-band but 0.49 mags fainter in H-band and 1.13 mags fainter in Ks-band. We use this relative photometry along with near-infrared synthetic modeling performed on the integrated light spectrum to derive component types of T1 for the primary and T5 for the secondary. Optical spectroscopy of this system obtained with Magellan/LDSS-3 is also presented. This is the fourth L/T transition binary to show a flux reversal in the 1-1.2 micron regime and this one has the largest flux reversal. Unless the secondary is itself an unresolved binary, the J-band magnitude difference between the secondary and primary shows that the J-band "bump" is indeed a real feature and not an artifact caused by unresolved binarity.

description: A series of 5,7-dibromo-2-benzoylbenzofurans were synthesized by the Rap–Stoermer condensation of 5,7-dibromosalicylaldehyde with diverse phenacyl bromides and evaluated for in-vitro antibacterial activities against methicillin-sensitive Staphylococcus aureus (MSSA) ATCC 29213, methicillin-resistant Staphylococcus aureus (MRSA) ATCC 43300, and MRSA ATCC 33591 by agar dilution method. The synergistic effects were determined by using the agar dilution checkerboard assay. The derivatives bearing carboxylic acid functional groups exhibited reasonable activity against MRSA strains with the best MIC = 32 µg/mL (9b, 9d). Moreover, the additive or synergistic interactions against MRSA strains was observed in six combinations (1b + cefuroxime/gentamicin, 1c + ciprofloxacin/gentamicin, 9b + gentamicin, and 9c + ciprofloxacin) with the fractional inhibitory concentration index (FICI) values in the range of 0.375–1.0. Significantly, the MICs of these antibiotics were reduced 2–4-fold. The results of the MTT assay illustrated the low mammalian cell cytotoxicity of these potent compounds.

description: A new series of α-substituted aromatic/heteroaromatic amino bisphosphonates have been synthesized by the three component condensation of diversely substituted amines with dialkyl phosphites and triethyl orthoformate without catalyst and solvent under microwave irradiation conditions. All the synthesized compounds were screened for their in vitro antibacterial, antifungal, antioxidant activity and molecular docking studies. The results revealed that among the synthesized compounds 3e, 3f, 3i and 3j showed high antibacterial, antifungal activity when compared to the standard drugs. Computational docking studies were made on the test compounds to predict how several amino bisphosphonates bind to DNA ligase. The bioactive compounds 3e and 3f have stronger inhibiting activity on human DNA ligase enzyme when compared with standard antibiotic ciprofloxacin. The compounds 3e, 3f, 3i and 3j showed better DPPH, NO and H2O2 scavenging activity.
The relationship of belief in control and commitment to life to cancer patients' inclination to use unproven cancer therapies
Creators: name: Skinn, Barbara Jean
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to explore the relationship of belief in control and commitment to life to the adult cancer patient's inclination to use unproven cancer therapies. A convenience sample of 40 lung cancer patients completed the Wallston's Multidimensional Health Locus of Control Scale, Crumbaugh's Purpose in Life Scale, Hiratzka's Alternative Therapy Scale, and a patient information sheet. The majority of participants exhibited a strong internal locus of control orientation and a strong commitment to life. Belief in control, commitment to life, and the degree of inclination to use unproven cancer therapies were not significantly associated. However, age was negatively correlated with inclination to use unproven cancer therapies. The majority of participants had heard of five or more unproven cancer remedies, and exhibited a strong inclination to use these unorthodox therapies. The most frequently used unproven therapies were anti-medicines - imagery, faith-healing, megadose vitamins, and taheebo. The rising popularity of these anti-medicines has been reported in the literature. The findings were discussed in relation to theoretical expectations, other research studies, and the methodological problems inherent in the study. Implications of the findings for nursing practice, theory, and education were suggested. Recommendations for further nursing research were made.

description: We study in detail a recently proposed mechanism for producing non-thermal dark photon dark matter at the end of inflation in the mass range $μ\,{\rm eV} \lesssim m \lesssim 10\,{\rm TeV}$. A tachyonic instability induced by a rolling inflaton leads to the coherent production of dark (abelian) gauge bosons with a peak in the power spectrum corresponding to the Hubble scale at the end of inflation. As the Universe expands after inflation the dark photons redshift and, at some point in their cosmic evolution, they obtain a mass. We focus in particular on the case where the dark photons are relativistic at the time their mass is generated and examine the associated cosmic evolution to compute the relic abundance today. We also examine the late time power spectrum demonstrating explicitly that it preserves the peak generated at the end of inflation. We show that the peak corresponds to small physical scales today, $\ell_{\rm today} \sim {\rm cm} - 100\,{\rm km}$, with large density fluctuations at $\ell_{\rm today}$ leading to a clumpy nature for the dark photon dark matter. We also discuss potential phenomenology and future directions, briefly commenting on the non-relativistic case.

description: Massive stars can shed material via steady, line-driven winds, eruptive outflows, or mass-transfer onto a binary companion. In the case of single stars, the mass is deposited by the stellar wind into the nearby environment. After the massive star explodes, the stellar ejecta interact with this circumstellar material (CSM), often-times resulting in bright X-ray line emission from both the shock-heated CSM and ejecta. The amount of material lost by the progenitor, the mass of ejecta, and its energetics all impact the bulk spectral characteristics of this X-ray emission. Here we present a grid of core-collapse supernova remnant models derived from models for massive stars with zero age main sequence masses of $\sim$ 10 - 30 M$_\odot$ evolved from the pre-main sequence stage with wind-driven mass-loss. Evolution is handled by a multi-stage pipeline of software packages. First, we use mesa (Modules for Experiments in Stellar Astrophysics) to evolve the progenitors from pre-main sequence to iron core collapse. We then use the Supernova Explosion Code (snec) to explode the mesa models, and follow them for the first 100 days following core-collapse. Finally, we couple the snec output, along with the CSM generated from mesa mass-loss rates, into the Cosmic-Ray Hydrodynamics code (ChN) to model the remnant phase to 7000 years post core-collapse. At the end of each stage, we compare our outputs with those found in the literature, and we examine any qualitative and quantitative differences in the bulk properties of the remnants and their spectra based on the initial progenitor mass, as well as mass-loss history.

Average optimality for continuous-time Markov decision processes in polish spaces

description: This paper is devoted to studying the average optimality in continuous-time Markov decision processes with fairly general state and action spaces. The criterion to be maximized is expected average rewards. The transition rates of underlying continuous-time jump Markov processes are allowed to be unbounded, and the reward rates may have neither upper nor lower bounds. We first provide two optimality inequalities with opposed directions, and also give suitable conditions under which the existence of solutions to the two optimality inequalities is ensured. Then, from the two optimality inequalities we prove the existence of optimal (deterministic) stationary policies by using the Dynkin formula. Moreover, we present a ``semimartingale characterization'' of an optimal stationary policy. Finally, we use a generalized Potlach process with control to illustrate the difference between our conditions and those in the previous literature, and then further apply our results to average optimal control problems of generalized birth--death systems, upwardly skip-free processes and two queueing systems. The approach developed in this paper is slightly different from the ``optimality inequality approach'' widely used in the previous literature.

description: We show how formal and rigid geometry can be used in the theory of complex singularities, and in particular in the study of the Milnor fibration and the motivic zeta function. We introduce the so-called analytic Milnor fiber associated to the germ of a morphism f from a smooth complex algebraic variety X to the affine line. This analytic Milnor fiber is a smooth rigid variety over the field of Laurent series C((t)). Its etale cohomology coincides with the singular cohomology of the classical topological Milnor fiber of f; the monodromy transformation is given by the Galois action. Moreover, the points on the analytic Milnor fiber are closely related to the motivic zeta function of f, and the arc space of X. We show how the motivic zeta function can be recovered as some kind of Weil zeta function of the formal completion of X along the special fiber of f, and we establish a corresponding Grothendieck trace formula, which relates, in particular, the rational points on the analytic Milnor fiber over finite extensions of C((t)), to the Galois action on its etale cohomology. The general observation is that the arithmetic properties of the analytic Milnor fiber reflect the structure of the singularity of the germ f.

description: Commutator methods are applied to get limiting absorption principles for the discrete standard and Molchanov-Vainberg Schrödinger operators $H_{\mathrm{std}}= Δ+V$ and $H_{\mathrm{MV}} = D+V$ on $\ell^2(\mathbb{Z}^d)$, with emphasis on $d=1,2,3$. Considered are electric potentials $V$ satisfying a long range condition of the type: $V-τ_j ^κV$ decays appropriately for some $κ\in \mathbb{N}$ and all $1 \leq j \leq d$, where $τ_j ^κ V$ is the potential shifted by $κ$ units on the $j^{\text{th}}$ coordinate. More comprehensive results are obtained for specific small values of $κ$, such as $κ=1,2,3,4$. In this article, we work in a simplified framework in which the main takeaway appears to be the existence of bands where a limiting absorption principle holds, and hence absolutely continuous (a.c.) spectrum, for $κ>1$ and $Δ$ (resp.\ $κ>2$ and $D$). Other decay conditions for $V$ arise from an isomorphism between $Δ$ and $D$ in dimension 2. Oscillating potentials are natural examples in application.

description: We analyze the exclusive rare $B \to K^{(*)} \ell^+ \ell^-$, $B \to K^{(*)} ν\bar ν$ and $B \to K^* γ$ decays in the Applequist-Cheng-Dobrescu model, which is an extension of the Standard Model in presence of universal extra dimensions. In particular, we consider the case of a single universal extra dimension. We study how spectra, branching fractions and asymmetries depend on the compactification parameter 1/R, and whether the hadronic uncertainty due to the form factors obscures or not such a dependence. We find that, using present data, it is possible in many cases to put a sensible lower bound to 1/R, the most stringent one coming from $B \to K^* γ$. We also study how improved experimental data can be used to establish stronger constraints to this model.

description: The Search for Extraterrestrial intelligence (SETI) is a scientific and cultural effort seeking evidence of intelligent life beyond earth. Radio SETI observes the radio spectrum for ''technosignatures" that could be produced by an advanced ET society. This work models radio SETI as an end-to-end system, and focuses on narrow-band intentional transmissions. We look at strategies to maximize the expected number of detections per year (DPY) of search. Assuming that ET civilizations will be associated with star systems, we want to maximize the number of stars that may be observed at one time. Assuming a representative star density, this requires maximizing the search volume in a cone defined by the detection range and field of view (FOV). The parameter trades are modified from the case where one simply maximizes signal-to-noise ratio. Instead, a joint optimization between FOV and sensitivity is needed. Some implications: 1) Instead of focusing on the terrestrial microwave window of 1-10 GHz, frequencies below 1 GHz may be optimal for detection rate due to the larger field of view; 2) Arrays of smaller dishes should be favored compared to a single dish of equivalent area; 3) Aperture arrays are desirable due to their large potential FOV. Many radio telescopes under development will provide both high sensitivity and large FOV, and should offer much improved SETI detection rates. Still higher DPY is needed, however, to achieve results in reasonable time horizons, which should be possible by greatly expanding computation capability to the next-generation wide-FOV antenna arrays.

description: Based on the latest experimental data of $B \to ππ$ and $πK$ modes, a model-independent analytical analysis is presented. The CP-averaged branching ratio difference $ΔR = R_c - R_n$ in $B\to πK$ decays with $R_c = 2Br(π^0K^-)/Br(π^-\bar{K}^0)$ and $R_n =Br(π^+K^-)/2Br(π^0\bar{K}^0)$ is reduced though it remains larger than the prediction from the standard model(SM) as both measured $R_n$ and $R_c$ are enhanced, which indicates that a room for new physics becomes smaller. The present data of $ππ$ decay reduce the ratio $|C/T|$ from the previous value of $|C/T|\simeq 0.8 $ to $|C/T| \simeq 0.65$, which is still larger than the theoretical estimations based on QCD factorization and pQCD. Within SM and flavor SU(3) symmetry, the current $πK$ data also diminish the ratio $|C'/T'|$ from the previous value $|C'/T'| \simeq 2$ to $|C'/T'| \simeq 1.16$ with a large strong phase $δ_{C'} \simeq -2.65$, while its value remains much larger than the one extracted from the $ππ$ modes. The direct CP violation $A_{CP}(π^0\bar{K}^0)$ is predicted to be $A_{CP}(π^0\bar{K}^0) = -0.15\pm0.03$, which is consistent with the present data. Two kinds of new effects in both strong and weak phases of the electroweak penguin diagram are considered. It is found that both cases can reduce the ratio to $|C'/T'| = 0.40\sim 0.80$ and lead to roughly the same predictions for CP violation in $π^0 K^0$.

description: In this paper, we study jumps of nonlinear DAEs caused by inconsistent initial values. First, we propose a simple normal form called the index-1 nonlinear Weierstrass form (INWF) for nonlinear DAEs. Then we generalize the notion of consistency projector for linear DAEs to the nonlinear case. By an example, we compare our proposed nonlinear consistency projectors with two existing consistent initialization methods to show that the two existing methods are not coordinate-free, i.e., the consistent points calculated by the two methods are not invariant under nonlinear coordinates transformations. Next we propose a singular perturbed system approximation for nonlinear DAEs, which is an ordinary differential equation (ODE) with a small perturbation parameter, we show that the solutions of the proposed perturbation system approximate both the jumps resulting from the nonlinear consistency projectors and the $\mathcal C^1$-solutions of the DAE. At last, we use a numerical simulation of a nonlinear DAE model arising from an electric circuit to illustrate the effectiveness of the proposed singular perturbed system approximation of DAEs.

description: We have developed a method to measure the mirror reflectivity of telescopes. While it is relatively easy to measure the local reflectivity of the mirror material, it is not so straightforward to measure the amount of light that it focuses in a spot of a given diameter. Our method is based on the use of a CCD camera that is fixed on the mirror dish structure and observes simultaneously part of the telescope's focal plane and the sky region around its optical axis. A white diffuse reflecting disk of known reflectivity is fixed in the telescopes focal plane. During a typical reflectivity measurement the telescope is directed to a selected star. The CCD camera can see two images of the selected star, one directly and another one as a spot focused by the mirror on the white disk. The ratio of the reflected starlight integrated by the CCD from the white disk to the directly measured one provides a precise result of the product of (mirror area x mirror reflectivity).
description: This method was first presented as a poster at the Cherenkov 2005 meeting "Towards a Network of Atmospheric Cherenkov Detectors VII" in April 2005, Palaiseau, France. Accepted by Astroparticle Physics

Thermodynamic consistency of liquid-gas lattice Boltzmann simulations

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Lattice Boltzmann simulations have been very successful in simulating liquid-gas and other multi-phase fluid systems. However, the underlying second order analysis of the equation of motion has long been known to be insufficient to consistently derive the fourth order terms that are necessary to represent an extended interface. These same terms are also responsible for thermodynamic consistency, i.e. to obtain a true equilibrium solution with both a constant chemical potential and a constant pressure. In this article we present an equilibrium analysis of non-ideal lattice Boltzmann methods of sufficient order to identify those higher order terms that lead to a lack of thermodynamic consistency. We then introduce a thermodynamically consistent forcing method.

Optimal regularity of Fourier integral operators with one-sided folds

Subjects: subject: Analysis of PDEs (math.AP)

description: We obtain optimal continuity in Sobolev spaces for the Fourier integral operators associated to singular canonical relations, when one of the two projections is a Whitney fold. The regularity depends on the type, $k$, of the other projection from the canonical relation ($k=1$ for a Whitney fold). We prove that one loses $(4+\frac{2}{k})^{-1}$ of a derivative in the regularity properties. The proof is based on the $L^2$ estimates for oscillatory integral operators.

description: Die Zielsetzung der Arbeit besteht in der Etablierung filmischer Naturerfahrung im Diskurs einer ökologischen Ästhetik. Wegweisend für die Studie ist die Verknüpfung phänomenologischer Filmtheorie mit dem Philosophieentwurf von Gernot Böhme, der das leibliche Empfinden als essenzielles Moment menschlicher Naturzugehörigkeit begreift. Ausgehend von den somatisch-affektiven Anteilen der Filmrezeption werden deren Dynamiken hinsichtlich der Konstitution von Naturbildern erschlossen. Als kulturelle Praktik des gesellschaftlichen Lebens nehmen Filme unmittelbar Einfluss auf die Genese ästhetischer Vorstellungen, die das Verhältnis des Menschen zu sich selbst und seiner Umwelt mitbestimmen. Der Einbezug des menschlichen Leibes in den filmischen Sinnbildungsprozess ist aus dem Blickwinkel der ökologischen Ästhetik von zentraler Bedeutung für individuelle und kollektive Naturkonzeptionen. Über die Verschränkung von ökologischer, phänomenologischer und rezeptionsästhetischer Forschung soll anhand der (im)mediaten, filmischen Erfahrung eine anschlussfähige Perspektive für die konkrete Umsetzung einer ökologischen Naturästhetik eröffnet werden.

(ii) The OC does not affect our results.

description: The motion of a mechanical resonator is intrinsically decomposed over a collection of normal modes of vibration. When the resonator is used as a sensor, its multimode nature often deteriorates or limits its performance and sensitivity. This challenge is frequently encountered in state-of-the-art optomechanical sensing platforms. We present a mechanical design strategy that ensures that optomechanical measurements can retrieve information on a single mechanical degree of freedom, and implement it in a sliced photonic crystal nanobeam resonator. A spectral design approach is used to make mechanical symmetries robust against practical disorder. The effectiveness of the method is evaluated by deriving a relevant figure of merit for continuous and pulsed measurement application scenarios. The method can be employed in any mechanical design that presents unwanted spurious mechanical modes. In the nanobeam platform, we experimentally show an increase of the signal to noise ratio of the mode of interest over the first spurious mode by four orders of magnitudes.
