description: Mass loss rates for the tenuous, hot winds of cool stars are extremely difficult to measure, yet they are a crucial ingredient in the stars' rotational evolution. We present a new method for measuring these mass loss rates in young, rapidly-rotating stars. These stars are known to support systems of "slingshot prominences" fed by hot wind material flowing up from the stellar surface into the summits of closed magnetic loop structures. The material gathers and cools near the co-rotation radius until its density becomes large enough that it is visible as a transient absorption feature in the hydrogen Balmer lines and strong resonance lines such as Ca II H \&\ K. Here we present the key insight that the sonic point usually lies well below the condensation region. The flow at the wind base is therefore unaffected by the presence of an overlying prominence, so we can use the observed masses and recurrence times of the condensations to estimate the mass flux in the wind. These measurements extend the relationship between mass loss rate per unit surface area and X-ray flux to span 5 orders of magnitude. They demonstrate no evidence of the suspected weakening of stellar mass loss rates at high X-ray flux levels.

description: O Movimento Empresa Júnior (MEJ) é constituído por empresas e empresários juniores que compartilham características e valores de fomento ao empreendedorismo, ao desenvolvimento pessoal e profissional e à capacidade de transformar o país. Imaginase que, em razão desta identidade, as empresas juniores (EJs) tendem à desburocratização, entretanto, identificou-se que as estratégias de crescimento do MEJ relacionam-se às dimensões burocráticas discutidas por Hall (1961). Este estudo objetivou a verificação da relação entre o nível de burocratização e o desempenho das empresas juniores do Nordeste sob a ótica de Menegassi (2007). Foi realizada uma pesquisa descritiva com método survey em 27 empresas juniores a fim de testar sete hipóteses que identificavam a associação entre as dimensões burocráticas e o desempenho das EJs. Como resultado, verificou-se que as empresas juniores apresentam um nível intermediário de burocratização e que não há correlação entre o desempenho e as dimensões burocráticas.

description: Introduction: Theory of mind (ToM) has been established as one of the most investigated and pronounced social cognitive deficits in schizophrenia. Yet, knowledge on whether measures of ToM can be used and compared across cultures is sparse. In this study, we used two simple, non-verbal ToM tests in patients with schizophrenia and non-clinical controls from China and Denmark to investigate whether culture has an impact on ToM performance. Methods: Sixty-six patients with schizophrenia (35 Chinese) and 67 matched non-clinical controls (38 Chinese) from China and Denmark were tested with Brünés Picture Sequencing Task and Animated Triangles Task. We compared three models for each outcome variable in order to investigate which model best fitted the data: the first model included group (controls, patients) as a predictor variable, the second included group and nationality (Chinese, Danish), and the third included both predictors and their interaction. Results: On most ToM subtests, culture seemed to play a role. Only performance on Brüne’s 1st order ToM were best described as similar in both countries. The second model had the best fit for most of the subtests indicating that the difference between patients and controls in China and Denmark, respectively, is similar. Conclusions: Caution to cultural differences should be taken when comparing ToM in Asian and Western patients with schizophrenia as well as healthy individuals.

description: Continuum models for the spatial dynamics of growing cell populations have been widely used to investigate the mechanisms underpinning tissue development and tumour invasion. These models consist of nonlinear partial differential equations that describe the evolution of cellular densities in response to pressure gradients generated by population growth. Little prior work has explored the relation between such continuum models and related single-cell-based models. We present here a simple stochastic individual-based model for the spatial dynamics of multicellular systems whereby cells undergo pressure-driven movement and pressure-dependent proliferation.We show that nonlinear partial differential equations commonly used to model the spatial dynamics of growing cell populations can be formally derived from the branching random walk that underlies our discrete model. Moreover, we carry out a systematic comparison between the individual-based model and its continuum counterparts, both in the case of one single cell population and in the case of multiple cell populations with different biophysical properties. The outcomes of our comparative study demonstrate that the results of computational simulations of the individual-based model faithfully mirror the qualitative and quantitative properties of the solutions to the corresponding nonlinear partial differential equations. Ultimately, these results illustrate how the simple rules governing the dynamics of single cells in our individual-based model can lead to the emergence of complex spatial patterns of population growth observed in continuum models.

By analyzing data from Altmetric.com and YouTube's API, it assesses how YouTube video features relate to citation impact. Initial results suggest that videos citing scientific publications and garnering high engagement-likes, comments, and references to other publications-may function as a filtering mechanism or even as a predictor of impactful research.

Year: 2021

description: Purpose: Pulmonary aspiration is an anesthesia-related complication that carries significant morbidity and mortality. The current preventive strategy against aspiration is the nothing by mouth (NPO) guidelines, yet there are a variety of situations that decrease the reliability of this evaluation tool. Gastric ultrasound (GUS) is a non-invasive technique to determine the prandial status in a patient with a questionable NPO status, however this is a tool that is not readily utilized in daily practice. The goal is to determine if a thirty-minute comprehensive, didactic virtual lecture with hands-on demonstration will increase anesthesia providers competency and confidence in using GUS. Method: In this prospective, quasi-experimental pretest-posttest study, we gave 117 anesthesia providers at a state’s professional biannual virtual conference and doctorly-prepared nurse anesthesia residents at a monthly program meeting a 30-minute virtual didactic lecture on the GUS examination along with a demonstration. Participant’s confidence and competence in image recognition and identification of the gastric antrum’s contents before and after the intervention was assessed through pre- and post-intervention tests.Results: After a single comprehensive 30-minute virtual lecture and demonstration, anesthesia providers and Resident Registered Nurse Anesthetists (RRNAs) are able to quickly increase their confidence and competence in gastric ultrasound image recognition. Implications: GUS image recognition is easily learned and can be an invaluable tool to the anesthesia provider. Obtaining baseline knowledge may increase the likelihood of participants to use this tool in their practice.

description: We analyse the mass density distribution in the centres of galaxies across five orders of magnitude in mass range. Using high-quality spiral galaxy rotation curves and infrared photometry from SPARC, we conduct a systematic study of their central dark matter fraction ($f_{\rm DM}$) and their mass density slope ($α$), within their effective radius. We show that lower-mass spiral galaxies are more dark matter dominated and have more shallow mass density slopes when compared with more massive galaxies, which have density profiles closer to isothermal. Low-mass ($M_{\star} \lesssim 10^{10}\, \rm M_{\odot}$) gas-rich spirals span a wide range of \fdm\ values, but systematically lower than in gas-poor systems of similar mass. With increasing galaxy mass, the values of \fdm\ decrease and the density profiles steepen. In the most massive late-type gas-poor galaxies, a possible flattening of these trends is observed. When comparing these results to massive ($M_{\star} \gtrsim 10^{10}M_{\odot}$) elliptical galaxies from SPIDER and to dwarf ellipticals from SMACKED, these trends result to be inverted. Hence, the values of both $f_{\rm DM}$ and $α$, as a function of $M_{\star}$, exhibit a U-shape trend. At a fixed stellar mass, the mass density profiles in dwarf ellipticals are steeper than in spirals. These trends can be understood by stellar feedback from a more prolonged star formation period in spirals, causing a transformation of the initial steep density cusp to a more shallow profile via differential feedback efficiency by supernovae, and by galaxy mergers or AGN feedback in higher-mass galaxies.

description: The Coulomb drag effect arises due to electron-electron interactions, when two metallic conductors are placed in close vicinity to each other. It manifests itself as a charge current or voltage drop induced in one of the conductors, if the current flows through the second one. Often it can be interpreted as an effect of rectification of the non-equilibrium $quantum$ noise of current. Here, we investigate the Coulomb drag effect in mesoscopic electrical circuits and show that it can be mediated by $classical$ fluctuations of the circuit collective mode. Moreover, by considering this phenomenon in the context of the full counting statistics of charge transport we demonstrate that not only the noise power, but also the third cumulant of current may contribute to the drag current. We discuss the situations, where this contribution becomes dominant.

Respiratory Patterns Classification using UWB Radar

Subjects: Respiratory pattern classification
Shapelet transform

description: Radar-based respiration monitoring has been increasingly popular among researchers in biomedical fields during the last decades since it is a contactless monitoring technique. It is very convenient for subjects because it does not impose any restrictions on subjects or require their cooperation. Meanwhile, recognizing alternations in respiratory patterns is an important early clue of the diagnosis of several cardiorespiratory diseases. Thus, a study of biomedical radar-based respiration monitoring and respiratory pattern classification is carried out in this thesis. Radar-based respiration monitoring technology has a shortcoming that the collected respiratory signal will be easily distorted by the body movement of the monitoring subjects or disturbed by environment noise because of the contactless measurement attribute. This shortcoming limits the application of the respiratory pattern classification model, that is, the existing models cannot be applied automatically since the distorted respiratory signal needs to be manually filtered out ahead of the classification. In this study, a new respiratory pattern classification strategy, which can be implemented full-automatic, is proposed. In this strategy, a class “moving” is introduced to classify the distorted signal, and the sampling window length is shortened to reduce the effect caused by the signal distortion. A performance requirement for the continuous respiratory pattern classification is also proposed based on its expected function that can alert the occurrence of the abnormal breathing patterns. Several models which can meet the proposed performance requirement are developed in this thesis based on the state-of-the-art pattern classification technique and the time-series-based shapelet transform algorithm. The proposed models can classify four breathing patterns including eupnea, Cheyne Stokes respiration, Kussmaul breathing and apnea. A radar-collected respiratory signal database is built in this study, and a respiration simulation model which can generate breath samples for pattern classification is developed in this thesis. The proposed models were tested and validated in batch and stream processing manner with independently collected data and continuously collected data, respectively.

Spinor-Helicity Formalism for Massless Fields in AdS${}_4$

Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this letter we suggest a natural spinor-helicity formalism for massless fields in AdS${}_4$. It is based on the standard realization of the AdS${}_4$ isometry algebra $so(3,2)$ in terms of differential operators acting on $sl(2,\mathbb{C})$ spinor variables. We start by deriving the AdS counterpart of plane waves in flat space and then use them to evaluate simple scattering amplitudes. Finally, based on symmetry arguments we classify all three-point amplitudes involving massless spinning fields. As in flat space, we find that the spinor-helicity formalism allows to construct additional consistent interactions compared to approaches employing Lorentz tensors.

description: We investigate the effective rheology of two-phase flow in a bundle of parallel capillary tubes carrying two immiscible fluids under an external pressure drop. The diameter of each tube varies along its length and the corresponding capillary threshold pressures are considered to be distributed randomly according to a uniform probability distribution. We demonstrate through analytical calculations that a transition from a linear Darcy regime to a non-linear behavior occurs while decreasing the pressure drop $ΔP$, where the total flow rate $\langle Q \rangle$ varies with $ΔP$ with an exponent $2$. This exponent for the non-linear regime changes when a lower cut-off $P_m$ is introduced in the threshold distribution. We demonstrate analytically that, in the limit where $ΔP$ approaches $P_m$, the flow rate scales as $\langle Q \rangle \sim (|ΔP|-P_m)^{3/2}$. We have also provided some numerical results in support to our analytical findings.

description: Recent experimental demonstrations of quantum coherence of the charge and flux states of Josephson junctions show that the quantum Josephson dynamics can be used to develop scalable quantum logic circuits. In this work, I review the basic concepts of Josephson tunneling and Josephson-junction qubits, and discuss two problems of this tunneling motivated by quantum computing applications. One is the theory of photon-assisted resonant flux tunneling in SQUID systems used to demonstrate quantum coherence of flux. Another is the problem of quantum measurement of charge with the SET electrometer. It is shown that the SET electrometer at the Coulomb blockade threshold is the quantum-limited detector with energy sensitivity reaching $\hbar/\sqrt{3}$ in the resonant-tunneling regime.

description: The purpose of the research was a comparative evaluation of production and economic results of agricultural farms according to area, production direction and intensity of production. The agricultural farms were situated in the Przysucha district (Masovian Voivodship). Results were compared between farms classified as different production directions. Research was carried out in 100 agricultural farms located on light soils – rye complexes. The evaluation was carried out using selected production and economic indices. Information and source data from farms were acquired using direct interviews in the form of a questionnaire. Research objects were intentionally selected from farms from the Przysucha district. Farms were divided into groups with the help of particular evaluation criteria, such as: production specialization, farm area size and intensity of production. On the basis of the research conducted, it was stated that achieving better results depended primarily on the chosen production direction. Orchards and vegetable farms, classified as small farms, due to their type of production, were more intense and achieved a higher value of global commodity production per 1 ha of UAA and production commodity. Relations discovered by the research concern farm specialization and how a farm functions in specified organizational as well as economic conditions.
Effects of Growth Orientations and Epitaxial Strains on Phase Stability of HfO$_2$ Thin Films

description: The discovery of ferroelectricity in both pure and doped HfO$_2$-based thin films have revitalized the interest in using ferroelectrics for nanoscale device applications. To take advantage of this silicon-compatible ferroelectric, fundamental questions such as the origin of ferroelectricity and better approach to controlled realization of ferroelectricity at the nanoscale need to be addressed. The emergence of robust polarization in HfO$_2$-based thin films is considered as the cumulative effect of various extrinsic factors such as finite-size effects and surface/interface effects of small grains, compressive stress, dopants, oxygen vacancies, and electric fields. The kinetic effects of phase transitions and their potential impacts on the emergence of ferroelectricity in HfO$_2$ at the nanoscale are not well understood. In this work, we construct the transition paths between different polymorphs of hafnia with density functional theory calculations and variable-cell nudged elastic band technique. We find that the transition barriers depend strongly on the mechanical boundary conditions and the transition from the tetragonal phase to the polar orthorhombic phase is a fast process kinetically under clamping. The effects of growth orientations and epitaxial strains on the relative stability of different phases of HfO$_2$ are investigated. The two orthorhombic phases, polar $Pca2_1$ and non-polar $Pbca$, become thermodynamically stable in (111)-oriented thin films over a wide range of epitaxial strain conditions. This work suggests a potential avenue to better stabilize the ferroelectric phase in HfO$_2$ thin films through substrate orientation engineering.

description: We present the next-to-leading order calculation of two four-jet event shape variables, the D parameter and acoplanarity differential distributions. We find large, more than 100% radiative corrections. The theoretical prediction for the D parameter is compared to L3 data obtained at the Z peak and corrected to hadron level.

description: Flatbands with extremely narrow bandwidths on the order of a few mili-electron volts can appear in twisted multilayer graphene systems for appropriate system parameters. Here we investigate the electronic structure of a twisted bi-bilayer graphene, or twisted double bilayer graphene, to find the parameter space where isolated flatbands can emerge as a function of twist angle, vertical pressure, and interlayer potential differences. We find that in twisted bi-bilayer graphene the bandwidth is generally flatter than in twisted bilayer graphene by roughly up to a factor of two in the same parameter space of twist angle $θ$ and interlayer coupling $ω$, making it in principle simpler to tailor narrow bandwidth flatbands. Application of vertical pressure can enhance the first magic angle in minimal models at $θ\sim 1.05^{\circ}$ to larger values of up to $θ\sim 1.5^{\circ}$ when $ P \sim 2.5$~GPa, where $θ\propto ω/ \upsilon_{F}$. Narrow bandwidths are expected in bi-bilayers for a continuous range of small twist angles, i.e. without magic angles, when intrinsic bilayer gaps open by electric fields, or due to remote hopping terms. We find that moderate vertical electric fields can contribute in lifting the degeneracy of the low energy flatbands by enhancing the primary gap near the Dirac point and the secondary gap with the higher energy bands. Distinct valley Chern bands are expected near $0^{\circ}$ or $180^{\circ}$ alignments.

description: Deviations from randomicity in In(x)Ga(1-x) As semiconductor alloys induced by elastic effects are investigated within the Keating potential. Our model is based on Monte Carlo simulations on large (4096 atoms) supercells, performed with two types of boundary conditions: Fully periodic boundary conditions represent the bulk, while periodic boundary conditions along the x and y directions and a free surface in the z direction simulate the epitaxial growth environment. We show that In-In correlations identified in the bulk tend to be enhanced in the epitaxially grown samples.

description: We analyse the role which the distance scale $ξ_K = v_F/T_K$ plays in the single-impurity Kondo problem using renormalization group improved perturbation theory. We derive the scaling functions for the local spin susceptibility in various limiting cases. In particular, we demonstrate exactly that the non-oscillating part of it should be short-range, i.e., vanish for distances $r \gg 1/k_F$ and show explicitly that the interior of the screening cloud {\it does not} exhibit weak coupling behavior.

description: Objective: A novel ECG classification algorithm is proposed for continuous cardiac monitoring on wearable devices with limited processing capacity. Methods: The proposed solution employs a novel architecture consisting of wavelet transform and multiple LSTM recurrent neural networks. Results: Experimental evaluations show superior ECG classification performance compared to previous works. Measurements on different hardware platforms show the proposed algorithm meets timing requirements for continuous and real-time execution on wearable devices. Conclusion: In contrast to many compute-intensive deep-learning based approaches, the proposed algorithm is lightweight, and therefore, brings continuous monitoring with accurate LSTM-based ECG classification to wearable devices. Significance: The proposed algorithm is both accurate and lightweight. The source code is available online [1].

description: High real-space-resolution atomic pair distribution functions of La_(1-x)Ca_(x)MnO_3 (x=0.12, 0.25 and 0.33) have been measured using high-energy x-ray powder diffraction to study the size and shape of the MnO_6 octahedron as a function of temperature and doping. In the paramagnetic insulating phase we find evidence for three distinct bond-lengths (~ 1.88, 1.95 and 2.15A) which we ascribe to Mn^{4+}-O, Mn^{3+}-O short and Mn^{3+}-O long bonds respectively. In the ferromagnetic metallic (FM) phase, for x=0.33 and T=20K, we find a single Mn-O bond-length; however, as the metal-insulator transition is approached either by increasing T or decreasing x, intensity progressively appears around r=2.15 and in the region 1.8 - 1.9A suggesting the appearance of Mn^{3+}-O long bonds and short Mn^{4+}-O bonds. This is strong evidence that charge localized and delocalized phases coexist close to the metal-insulator transition in the FM phase.

description: The level-$1$ integrable highest weight modules of $U_q(\widehat{sl}_2)$ admit a level-$0$ action of the same algebra. This action is defined using the affine Hecke algebra and the basis of the level-$1$ module generated by components of vertex operators. Each level-$1$ module is a direct sum of finite-dimensional irreducible level-$0$ modules, whose highest weight vector is expressed in terms of Macdonald polynomials. This decomposition leads to the fermionic character formula for the level-$1$ modules.

The likely Fermi detection of the Be X-ray binary GRO J1008-57: hint for gamma-ray production in neutron-star X-ray binaries

description: In our search for gamma-ray emission from Be X-ray binaries from analysis of the data obtained with the Large Area Telescope (LAT) on board the Fermi Gamma-Ray Space Telescope, we find likely detection of GRO J1008-57. The binary has an orbital period of 249.48 days, and it is only significantly detected in its orbital phase 0.8--0.9 (>4 sigma). Further light curve analysis indicates that the detection is probably largely due to an emitting event in one orbital cycle around year 2012--2013, following a giant X-ray outburst of the source. This property of having occasional gamma-ray emitting events is similar to that seen in another high-mass X-ray binary 4U 1036-56. However, models considering possible gamma-ray emission from an accreting neutron star have difficulty in explaining the observed 10^{34} erg s^{-1} luminosity of the source, unless the distance was largely over-estimated. Further observational studies are required, in order to more clearly establish the high-energy emission properties of GRO J1008-57 or similar high-mass X-ray binaries and find clues for understanding how gamma-ray emission is produced from them.

description: A method to treat a N-component percolation model as effective one component model is presented by introducing a scaled control variable $p_{+}$. In Monte Carlo simulations on $16^{3}$, $32^{3}$, $64^{3}$ and $128^{3}$ simple cubic lattices the percolation threshold in terms of $p_{+}$ is determined for N=2. Phase transitions are reported in two limits for the bond existence probabilities $p_{=}$ and $p_{\neq}$. In the same limits, empirical formulas for the percolation threshold $p_{+}^{c}$ as function of one component-concentration, $f_{b}$, are proposed. In the limit $p_{=} = 0$ a new site percolation threshold, $f_{b}^{c} \simeq 0.145$, is reported.

description: Low-scale leptogenesis is most efficient in the limit of an extreme mass degeneracy of right-handed neutrino flavours. Two variants of this situation are of particular interest: large neutrino Yukawa couplings, which boost the prospects of experimental scrutiny, and small ones, which may lead to large lepton asymmetries surviving down to T < 5 GeV. We study benchmarks of these cases within a "complete" framework which tracks both helicity states of right-handed neutrinos as well as their kinetic non-equilibrium, and includes a number of effects not accounted for previously. For two right-handed flavours with GeV-scale masses, Yukawa couplings up to $|h| \sim 0.7 \times 10^{-5}$ are found to be viable for baryogenesis, with $ΔM/M \sim 10^{-8}$ as the optimal degeneracy. Late-time lepton asymmetries are most favourably produced with $ΔM/M \sim 10^{-11}$. We show that the system reaches a stationary state at T < 15 GeV, in which lepton asymmetries can be more than $10^3$ times larger than the baryon asymmetry, reach flavour equilibrium, and balance against helicity asymmetries.

Improved Determination of $α(M_{\rm Z}^2$) and the Anomalous Magnetic Moment of the Muon

description: We reevaluate the hadronic contribution to the running of the QED fine structure constant \aqed at $s=M_{\rm Z}^2$. We use data from \ee\ annihilation and $τ$ decays at low energy and at the $q\bar{q}$ thresholds, where resonances occur. Using so-called spectral moments and the Operator Product Expansion (OPE), it is shown that a reliable theoretical prediction of the hadronic production rate $R(s)$ is available at relatively low energies. Its application improves significantly the precision on the hadronic vacuum polarization contribution. We obtain \daqedhZ $=(277.8\pm2.6)\times10^{-4}$ yielding $α^{-1}(M_{\rm Z}^2)=128.923\pm0.036$. Inserting this value in a global electroweak fit using current experimental input, we constrain the mass of the Standard Model Higgs boson to be $M_{\rm Higgs}=129^{+103}_{-62}~{\rm GeV}$. Analogously, we improve the precision of the hadronic contribution to the anomalous magnetic moment of the muon for which we obtain $a_μ^{\rm had}=(695.1\pm7.5)\times 10^{-10}$.

description: The slow, dense winds observed in evolved asymptotic giant branch (AGB) stars are usually attributed to a combination of dust formation in the dynamical inner atmosphere and momentum transfer from stellar photons interacting with the newly formed dust particles. Wind models calculated with the DARWIN code, using this mass-loss scenario, have successfully produced outflows with dynamical and photometric properties compatible with observations, for both C-type and M-type AGB stars. Presented here is an overview of the DARWIN models currently available and what output these models produce, as well as future plans.
