description: Graphene oxide (GO) membranes are considered promising for water purification applications. We synthesized a novel GO membrane using inorganic silane as a cross linker. Briefly, a pH 3 GO solution was filtrated through polyethersulfone (PES) membrane supports by vacuum filtration. The GO layers deposited on the PES supports were subsequently soaked in a saturated sodium metasilicate solution for crosslinking and stabilization. As a final step, the readily stabilized GO membranes were transferred into a 10% H2SO4 solution for further stabilization. The GO membrane exhibits unique rejection properties to uncharged organic species (~ 85%) and ionic species (~6%). A high water flux of 39 L/m2/h and a reasonable back solute flux of 0.011 mol/m2/h were observed with 0.25M trisodium citrate dehydrate (TSC) as draw solution in forward osmosis (FO). The GO membrane also demonstrates some interesting Janus effects and enables directional water gating (by blocking the permeation in one direction while allowing the permeation in the other direction).

description: The instrumental advances made in this new era of 4-meter class solar telescopes with unmatched spectropolarimetric accuracy and sensitivity, will enable the study of chromospheric magnetic fields and their dynamics with unprecedented detail. In this regard, spectropolarimetric diagnostics can provide invaluable insight into magneto-hydrodynamic (MHD) wave processes. MHD waves and, in particular, Alfvénic fluctuations associated to particular wave modes, were recently recognized as important mechanisms not only for the heating of the outer layers of the Sun's atmosphere and the acceleration of the solar wind, but also for the elemental abundance anomaly observed in the corona of the Sun and other Sun-like stars (also known as first ionisation potential; FIP) effect. Here, we take advantage of state-of-the-art and unique spectropolarimetric IBIS observations to investigate the relation between intensity and circular polarisation (CP) fluctuations in a sunspot chromosphere. Our results show a clear link between the intensity and CP fluctuations in a patch which corresponds to a narrow range of magnetic field inclinations. This suggests the presence of Alfvénic perturbations in the sunspot.

description: The observable line shape of the spontaneous emission depends on the procedure of atom's excitation. The spectrum of radiation emitted by a two-level atom excited from the ground state by a pi pulse of the resonant pump field is calculated for the case when the Rabi frequency is much larger than the relaxation rate. It is shown that the central part of the spectral distribution has a standard Lorentzian form, whereas for detunings from the resonance that are larger than the Rabi frequency the spectral density falls off faster. The shape of the wings of the spectral line is sensitive to the form of the pi pulse. The implications for the quantum Zeno effect theory and for the estimates of the duration of quantum jumps are discussed.

description: The macroscopic magnetic characterization of the Mn(II) - nitronyl nitroxide free radical chain (Mn(hfac)2(R)-3MLNN) evidenced its transition from a 1-dimensional behavior of ferrimagnetic chains to a 3-dimensional ferromagnetic long range order below 3 K. Neutron diffraction experiments, performed on a single crystal around the transition temperature, led to a different conclusion : the magnetic Bragg reflections detected below 3 K correspond to a canted antiferromagnet where the magnetic moments are mainly oriented along the chain axis. Surprisingly in the context of other compounds in this family of magnets, the interchain coupling is antiferromagnetic. This state is shown to be very fragile since a ferromagnetic interchain arrangement is recovered in a weak magnetic field. This peculiar behavior might be explained by the competition between dipolar interaction, shown to be responsible for the antiferromagnetic long range order below 3 K, and exchange interaction, the balance between these interactions being driven by the strong intrachain spin correlations. More generally, this study underlines the need, in this kind of molecular compounds, to go beyond macroscopic magnetization measurements.

Magnetically regulated disk-formation in the inner 100 au region of the Class 0 young stellar object OMC-3/MMS~6 resolved by JVLA and ALMA

description: We have carried out polarization calibration for archival JVLA ($\sim$9 mm) full polarization observations towards the Class 0 young stellar object (YSO) OMC-3/MMS 6 (also known as HOPS-87), and then compared with the archival ALMA 1.2 mm observations. We found that the innermost $\sim$100 au region of OMC-3/MMS 6 is likely very optically thick (e.g., $τ\gg$1) at $\sim$1 mm wavelength such that the dominant polarization mechanism is dichroic extinction. It is marginally optically thin (e.g., $τ\lesssim$1) at $\sim$9 mm wavelength such that the JVLA observations can directly probe the linearly polarized emission from non-spherical dust. Assuming that the projected long axis of dust grains is aligned perpendicular to magnetic field (B-field) lines, we propose that the overall B-field topology resembles an hourglass shape, while this "hourglass" appears $\sim$40$^{\circ}$ inclined with respect to the previously reported outflow axis. The geometry of this system is consistent with a magnetically regulated dense (pseudo-)disk. Based on the observed 29.45 GHz flux density and assuming a dust absorption opacity $κ^{abs}_{29.45\,GHz}=$0.0096 cm$^{2} $g$^{-1}$, the derived overall dust mass within a $\sim$43 au radius is $\sim$14000 $M_{\oplus}$. From this case study, it appears to us that some previous 9 mm surveys towards Class 0/I YSOs might have systematically underestimated dust masses by one order of magnitude, owing to that they assumed the too high dust absorption opacity ($\sim$0.1 cm$^{2}$ g$^{-1}$) for $\sim$9 mm wavelengths but without self-consistently considering the dust scattering opacity.

description: We perform transmission spectroscopy on single quantum dots and examine the effects of a resident carriers spin, the incident laser spot size, polarization, and power on the experimental contrast. We demonstrate a factor of 4 improvement in the maximum contrast by using a solid immersion lens to decrease the spot area. This increase yields a maximum signal to noise ratio of 2000 Hz-1/2, which will allow for MHz detection frequencies. We anticipate that this improvement will allow further investigation of spectral fluctuation and open up the feasibility for an all-optical read-out of an electron spin in a quantum dot.

I examined the holotype and additional specimens of Torbda takachihoensis Momoi, 1966, and concluded that this species should be transferred from Torbda to Pterocryptus. The character states of this species are completely accorded with the generic character states of Pterocryptus proposed by Townes (1970) and Gupta & Gupta (1983), e.g., pleural carina of propodeum present between anterior transverse carina and hind coxa (Fig. 2B) (absent in Torbda) and T1 without a pair of triangular teeth at base (Fig. 2G). In this study, I transferred generic position of this species below.

description: The proper determination of soil moisture on different scales is important for applications in a variety of fields. We aim to develop a high-level soil moisture product with high temporal and spatial resolution by assimilating the multilayer soil moisture product SCATSAR-SWI (Scatterometer Synthetic Aperture Radar Soil Water Index) into the surface model SURFEX. In addition, we probe the impact of the findings on the Numerical Weather Prediction (NWP) in Austria. The data assimilation system consists of the NWP model AROME and the SURFEX Offline Data Assimilation, which provide atmospheric forcing and soil moisture fields as mutual input. To address the known sensitivity of the employed simplified Extended Kalman Filter to the specification of errors, we compute the observation error variances of the SCATSAR-SWI locally using Triple Collocation Analysis and implement them into the assimilation system. The verification of the forecasted 2 m temperature and relative humidity against measurements of Austrian weather stations shows that the actual impact of the local error approach on the atmospheric forecast is slightly positive to neutral compared to the standard error approach, depending on the time of the year. The direct verification of the soil moisture analysis against a gridded water balance product reveals a degradation of the unbiased root mean square error for small observation errors.

description: We examine the implications of several recently derived conditions [Hillery and Zubairy, Phys. Rev. Lett. 96, 050503 (2006)] for determining when a two-mode state is entangled. We first find examples of non-Gaussian states that satisfy these conditions. We then apply the entanglement conditions to the study of several linear devices, the beam splitter, the parametric amplifier, and the linear phase-insensitive amplifier. For the first two, we find conditions on the input states that guarantee that the output states are entangled. For the linear amplifier, we determine in the limit of high and no gain, when an entangled input leads to an entangled output. Finally, we show how application of two two-mode entanglement conditions to a three-mode state can serve as a test of genuine three-mode entanglement.

Remarks. Momoi (1966) used the length of postpetiole for the separation this species from P. uchidai, while this character states shows intraspecific variation. This species resembles P. uchidai and can be distinguished by the following combination of character states in female: posterior margin of T2–T7 with white band (Fig. 10I) (without white band in P. uchidai); T1 2.1–2.2 times as long as maximum width (1.9–2.0 times in P. uchidai); hind TS1 2.1 times as long as TS2 (2.3 times in P. uchidai). On the other hand, no difference between the males of P. takachihoensis and P. uchidai is recognizable and thus further comparison with molecular data of them are necessary.

description: Brownian ratchet has emerged as a promising tool for understanding motion mechanism of molecules and proteins, and dynamically manipulating particles in non-equilibrium thermodynamics state. Here, we propose and experimentally demonstrate a new type of optical Brownian ratchets, which is generated by using controllable phase profiles in holographic optical trapping system. The potential energy profiles are dynamically switched in on-off mode, controlled by Labview software. Experimental results reveal that not only high speed but also large step distance can be easily achieved in Brownian ratchet, in which the average velocity of forward motion is about 28 μm/s and step distance is about 42 μm. More importantly, its motion path, step distance and velocity can be easily changed by manipulating its holograms, which exhibits high flexibility, easy control and excellent capability. This technique provides new opportunities for exploring non-equilibrium dynamics at the nanoscale level, and developing novel nanoparticle manipulation.

Accuracy of slow-roll formulae for inflationary perturbations: implications for primordial black hole formation

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We investigate the accuracy of the slow-roll approximation for calculating perturbation spectra generated during inflation. The Hamilton-Jacobi formalism is used to evolve inflationary models with different histories. Models are identified for which the scalar power spectra computed using the Stewart-Lyth slow-roll approximation differ from exact numerical calculations using the Mukhanov perturbation equation. We then revisit the problem of primordial black holes generated by inflation. Hybrid-type inflationary models, in which the inflaton is trapped in the minimum of a potential, can produce blue power spectra and an observable abundance of primordial black holes. However, this type of model can now be firmly excluded from observational constraints on the scalar spectral index on cosmological scales. We argue that significant primordial black hole formation in simple inflation models requires contrived potentials in which there is a period of fast roll towards the end of inflation. For this type of model, the Stewart-Lyth formalism breaks down. Examples of such inflationary models and numerical computations of their scalar fluctuation spectra are presented.

description: We describe the methodology applied for the retrieval of global LAI, FAPAR and FVC from Advanced Very High Resolution Radiometer (AVHRR) onboard the Meteorological-Operational (MetOp) polar orbiting satellites also known as EUMETSAT Polar System (EPS). A novel approach has been developed for the joint retrieval of three parameters (LAI, FVC, and FAPAR) instead of training one model per parameter. The method relies on multi-output Gaussian Processes Regression (GPR) trained over PROSAIL EPS simulations. A sensitivity analysis is performed to assess several sources of uncertainties in retrievals and maximize the positive impact of modeling the noise in training simulations. We describe the main features of the operational processing chain along with the current status of the global EPS vegetation products, including details about its overall quality and preliminary assessment of the products based on intercomparison with equivalent (MODIS, PROBA-V) satellite vegetation products.

description: Consider a binary tree, to the vertices of which are assigned independent Bernoulli random variables with mean $p\leq1/2$. How many of these Bernoullis one must look at in order to find a path of length $n$ from the root which maximizes, up to a factor of $1-ε$, the sum of the Bernoullis along the path? In the case $p=1/2$ (the critical value for nontriviality), it is shown to take $Θ(ε^{-1}n)$ steps. In the case $p<1/2$, the number of steps is shown to be at least $n\cdot\exp(\operatorname {const}ε^{-1/2})$. This last result matches the known upper bound from [Algorithmica 22 (1998) 388--412] in a certain family of subcases.

This opens for me the following questions: how does the act of inviting and collaborating in the shoreline, and then surrendering to the outcomes, manifest physically, spiritually, and psychologically in the filmmaking process? How do these invited variables transform the observer and the celluloid? These questions are important for me as an artist who is re-situating myself in my practice. I’m relearning how to be a filmmaker; as a restorative art form and as a way to understand, and contribute to, the world in which I create. I'm opening the camera and myself to possibilities of re-imprinting, unlearning and responding in new ways. In this slowing down to see and listen more deeply, is there potential for creative re-integration through immersion in place and material practice? How can we consider acts of reciprocity in our creative work with natural elements? When I consider the shoreline and its inhabitants as teachers and partners in my making, what does that do to the hierarchy of filmmaking outside of the film industry? Through material engagement, I'm exploring forms of renewal and restoration in collaboration with the sea, discovering ways of making films with the ocean using seaweed and seawater. The shoreline begins to function as a space of potentiality and transformation. Perhaps it is in response to big picture, urgent topics that I’m opening a tiny lens on more intimate collaborators. Maybe there are connections to the macro through the micro. I'm wondering how we will be changed if we acknowledge this Earth as the knower and ourselves as discoverable. How will surrendering to the timeless patience of the sea change my ways of making?

description: Health monitoring is essential to enable timely and appropriate care for newborns. However, this is limited in low-to-middle-income countries due to insufficient resources and health staff. This thesis examines accessible newborn health monitoring. It develops software to monitor heart and lung health using digital stethoscopes and video cameras. From this, estimating vital signs and automated health assessments are performed.
Distribution of an Ohmic current in the close vicinity of a quantum point contact

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We present the essential findings of the screening theory of the integer quantum Hall effect (IQHE) considering a quantum point contact (QPC). Our approach is to solve the Poisson and the Schroedinger equations self-consistently, taking into account electron interactions, within a Hartree type approximation for a two dimensional electron gas (2DEG) subject to high perpendicular magnetic fields. The Coulomb interaction between the electrons separates 2DEG into two co-existing regions, namely quasi-metallic compressible and quasi-insulating incompressible regions, which exhibit peculiar screening and transport properties. In the presence of an external current, we show that this current is confined into the incompressible regions where the drift velocity is finite. In particular, we investigate the distribution of these incompressible strips and their relation with the quantum Hall plateaus considering a quasi 1D constriction, i.e. a QPC.
A pilot study to assess nursing faculty knowledge of "Stop the bleed": a population health initiative
Creators: name: Curley, Linda J.
Publisher: name: No Publisher Supplied
Year: 2021

description: Purpose of Project: This project aimed to determine if educating nursing faculty about the Stop the Bleed Initiative (STBI) through an online video would increase awareness and knowledge and determine barriers to participants taking the STBI training course. Methodology: The purpose of this project was achieved by educating nursing faculty about the Stop the Bleed Initiative (STBI). This goal was achieved by utilizing an online video followed by a short Qualtrics survey. Participating nursing faculty answered questions beginning with demographics, prior knowledge, and previous training in STBI. More responses requested were barriers to taking the training course, whether they characterized the education as valuable, whether they planned to disseminate the knowledge to students, and whether they believed the training could positively affect health outcomes. Results: The results demonstrated that participants found the education valuable and determined it could positively affect health outcomes. Barriers were identified in the responses, as well as additional remarks. Implications for practice: Educating nursing faculty utilizing an online video was determined to have the potential to positively affect health outcomes. The education of nursing faculty to recognize life-threatening bleeding and immediately respond with pressure or wound packing or the placement of a tourniquet may improve trauma patient health outcomes.

description: The electrical coupling between myocytes and fibroblasts and the spacial distribution of fibroblasts within myocardial tissues are significant factors in triggering and sustaining cardiac arrhythmias but their roles are poorly understood. This article describes both direct numerical simulations and an asymptotic theory of propagation and block of electrical excitation in a model of atrial tissue with myocyte-fibroblast coupling. In particular, three idealised fibroblast distributions are introduced: uniform distribution, fibroblast barrier and myocyte strait, all believed to be constituent blocks of realistic fibroblast distributions. Primary action potential biomarkers including conduction velocity, peak potential and triangulation index are estimated from direct simulations in all cases. Propagation block is found to occur at certain critical values of the parameters defining each idealised fibroblast distribution and these critical values are accurately determined. An asymptotic theory proposed earlier is extended and applied to the case of a uniform fibroblast distribution. Biomarker values are obtained from hybrid analytical-numerical solutions of coupled fast-time and slow-time periodic boundary value problems and compare well to direct numerical simulations. The boundary of absolute refractoriness is determined solely by the fast-time problem and is found to depend on the values of the myocyte potential and on the slow inactivation variable of the sodium current ahead of the propagating pulse. In turn, these quantities are estimated from the slow-time problem using a regular perturbation expansion to find the steady state of the coupled myocyte-fibroblast kinetics. The asymptotic theory gives a simple analytical expression that captures with remarkable accuracy the block of propagation in the presence of fibroblasts.

Energy efficiency of gas separation by Pressure Swing adsorption
Creators: name: McLean, Christopher Ross
Publisher: name: University of British Columbia
Year: 2009

description: Pressure Swing Adsorption (PSA) is a method of separating a mixture of gases into its various components. Cyclic pressure and flow variations, in the presence of a selectively adsorbent material, are used to concentrate one species or group of species at one end of an adsorbent filled vessel, while the other species or group of species is concentrated at the other end. When PSA is used in separating gases, the necessity of gas pressurization and depressurization implies that the process can become very energy intensive. This is especially true in low capacity systems that require small compressors and/or vacuum pumps. There are many ways in which traditional PSA processes have been modified in order to reduce the amount of pressurization energy that is lost. One method is to use high pressure gas from one adsorbent bed to pressurize another adsorbent bed. This "equalization" recovers some of the energy used to initially compress the gas. However, as the gas is throttled from one bed to the other, irreversibilities are introduced into the process. In this thesis, the irreversibilities that are due to throttling are separated from those which are inherent in the PSA process and cannot be removed. The work required to produce a certain amount of gas by various simple PSA cycles is compared to the reversible work required to produce that amount of gas, based on the availability (or exergy) of the gas. The ratio of the reversible work to the actual work required for the PSA cycle is defined as the second law efficiency, and is compared for three cycles: the Four-Step cycle, the Ideal Four-Step cycle, and the Ideal Three-Step cycle. The irreversible expansion of gas through throttling valves is shown to account for the majority of the energy losses of the Four-Step cycle. Useful work (represented by the increase in availability of the product and exhaust) is found to be very small compared with the work required by the cycles. The true bed losses, inherent in the PSA process, are found to be similar in magnitude to the useful work, but much less than the energy lost by the throttling irreversibilities. The work required per mole of product to separate the gases decreases as the pressure ratio increases, and the second law efficiency increases with pressure ratio. For the cycle with no energy recovery, the second law efficiency varies widely with the selectivity ratio. A high selectivity ratio (implying a low separation factor) implies more work is required for the separation and the second law efficiency is lower. For the cycles with full recovery of the expansion energy, the work required and the second law efficiency are relatively independent of the selectivity ratio. The equilibrium based semi-analytical results are confirmed by the use of a numerical "Multiple-Cell" model. This model is also used to show that diffusion does not affect the second law efficiency of a cycle when energy recovery is present.

description: Rydberg-atom quantum simulators are of keen interest because of their possibilities towards high-dimensional qubit architectures. Here we report three-dimensional conformation spectra of quantum-Ising Hamiltonian systems with programmed qubit connections. With a Rydberg-atom quantum simulator, various connected graphs, in which vertices and edges represent atoms and blockaded couplings, respectively, are constructed in two or three-dimensional space and their eigenenergies are probed during their topological transformations. Star, complete, cyclic, and diamond graphs, and their geometric intermediates, are tested for four atoms and antiprism structures for six atoms. Spectroscopic resolution (dE/E) less than 10% is achieved and the observed energy level shifts and merges through structural transformations are in good agreement with the model few-body quantum-Ising Hamiltonian.

description: Recently, a reconsideration of Drell-Yan cross sections at moderate energies and masses has suggested the possibility of relevant enhancements of the cross sections in some kinematical regions. If confirmed, these predictions could largely affect the planning of Drell-Yan experiments aimed at transverse spin measurements after 2010. More in general, the problem is present of a precision measurement of the $τ$ dependence of Drell-Yan cross sections. Here we discuss the feasibility of such a measurement within short time at the COMPASS apparatus, and its relevance for the PANDA experiment.
