Accretion flow and jet in the hard state of MAXI J1820+070
Creators: name: Zdziarski, Andrzej
Publisher: name: Zenodo
Year: 2021

description: A number of results on the accretion flow and the jet in the hard state of MAXI J1820+070 have been obtained. The accretion disc is found to have the inner radius of some tens of gravitational radii, Rg. The hot accretion flow, emitting hard X-rays, overlaps with the disc, and is stratified, consisting of at least two components with different spectral slopes. The harder component dominates the bolometric luminosity and is located downstream of the softer one. The electron distribution of the harder component is hybrid, consisting of mildly relativistic Maxwellian electrons followed by a power law tail. The spectra measured by NuSTAR and INTEGRAL extend up to ~2 MeV. This results in copious e± pair production in photon-photon collisions. The equilibrium pair density in the hot flow still remains low due to its relatively large optical depth. However, pairs are likely to be produced in the jet base, providing the electrons for the jet synchrotron emission. The jet parameters are determined based on the spectral and timing results of the large multiwalength campaign described in Tetarenko et al. 2021 (MNRAS, 504, 3862). The initial part of the jet forms a magnetically-dominated acceleration and collimation zone. The jet starts emitting above z0~104Rg. Its synchrotron emission by power-law electrons is partially self-absorbed up to the break frequency of ~(2−3)1013Hz. The half-opening angle is Θ ≈ 1−1.5°, the bulk Lorentz factor is G ≈ 1.8−4, and the magnetic field strength at z0 is B ≈ 104G. The jet power depends on the uncertain pair abundance, but it can be as large as its maximum value of Pj ≈ Ṁc2, where Ṁ is the accretion rate.

description: X-ray reflectivity studies demonstrate the condensation of a monovalent ion at the electrified interface between electrolyte solutions of water and 1,2-dichloroethane. Predictions of the ion distributions by standard Poisson-Boltzmann (Gouy-Chapman) theory are inconsistent with these data at higher applied interfacial electric potentials. Calculations from a Poisson-Boltzmann equation that incorporates a non-monotonic ion-specific potential of mean force are in good agreement with the data.

description: We have performed x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD) studies of the diluted ferromagnetic semiconductor Zn$_{1-\textit{x}}$Cr$_\textit{x}$Te doped with iodine (I) or nitrogen (N), corresponding to electron or hole doping, respectively. From the shape of the Cr $2p$ absorption peak in the XAS spectra, it was concluded that Cr ions in the undoped, I-doped and lightly N-doped samples are divalent (Cr$^{2+}$), while Cr$^{2+}$ and trivalent (Cr$^{3+}$) coexist in the heavily N-doped sample. This result indicates that the doped nitrogen atoms act as acceptors but that doped holes are located on the Cr ions. In the magnetic-field dependence of the XMCD signal at the Cr $2p$ absorption edge, ferromagnetic behaviors were observed in the undoped, I-doped, and lightly N-doped samples, while ferromagnetism was considerably suppressed in heavily N-doped sample, which is consistent with the results of magnetization measurements.

description: Air filtration serves to reduce concentrations of particles in indoor environments. Most standalone, also referred to as portable or in-room, air filtration systems use HEPA filters, and cost generally scales with the clean air delivery rate. A “do-it-yourself” lower-cost alternative, known as the Corsi-Rosenthal Box, that uses MERV-13 filters coupled with a box fan has been recently proposed, but lacks systematic performance characterization. We have characterized the performance of a five-panel Corsi-Rosenthal air cleaner using both research-grade instrumentation (an aerodynamic particle sizer, APS) and a low-cost particle sensor. Measurements of size-resolved and overall decay rates of aerosol particles larger than 0.5 microns emitted into rooms of varying size with and without the air cleaner allowed for determination of the apparent clean air delivery rate—both as a function of size and integrated across particle sizes for a number-weighted median particle diameter of 1.2 ± 0.12 microns. The measurements made in the different rooms produced similar results, demonstrating the robustness of the method used. The size-integrated effective clean air delivery rate increases with fan speed, from about 600 to 850 ft3 min−1 (1019 to 1444 m3 h−1) as determined with the APS. The low-cost sensor yields similar clean air delivery rates as the APS, demonstrating a method by which others who lack access to research-grade instruments can determine the effectiveness of Corsi-Rosenthal Boxes that use components that differ from those used here. Overall, our results demonstrate that our Corsi-Rosenthal air cleaner efficiently reduces suspended particle concentrations in indoor environments.

description: Oil-based cuttings (OBCs) produced by shale gas exploitation are classified as hazardous waste. Their appropriate utilization and disposal is a key issue that urgently needs to be resolved. A single-phase microemulsion (SPM) has ultra-low interfacial tension and strong solubilization ability. In view of this, based on an analysis of the characteristics of OBCs, SPMs have been selected for their cleaning. The effects of microemulsion components and other conditions on the cleaning efficacy have been explored, as well as the deoiling mechanism and the recycling efficiency of the SPM. Our results have shown that sodium dodecylbenzene sulfonate (SDBS), n-butanol, water, and white oil in appropriate proportions can form an effective SPM. The oil content (OC) of OBCs after cleaning was reduced from 11.89% (±0.32%) to 1.13% (±0.02%) when the proportions of the aforementioned components of the SPM were 14.3%, 14.3%, 66.6%, and 4.8%, respectively. The OC of the residue further decreased to 0.28% (±0.05%) after a second cleaning with an alkaline solution. The optimum SPM conditions for cleaning OBCs were identified as a stirring speed of 200 rpm, a temperature of 30 °C, a cleaning time of 30 min, and a solid to liquid mass to volume ratio of 1:4. The main mechanism whereby the SPM cleans the OBCs is that the former reduces the combined work and adhesion work required for the removal of oil droplets from the cuttings, so that the adhesive oil is easily gathered up. Furthermore, the gathered oil phase is solubilized by the SPM.
Path representation of su(2)_k states II: Operator construction of the fermionic character and spin-1/2--RSOS factorization

description: This is the second of two articles (independent of each other) devoted to the analysis of the path description of the states in su(2)_k WZW models. Here we present a constructive derivation of the fermionic character at level k based on these paths. The starting point is the expression of a path in terms of a sequence of nonlocal (formal) operators acting on the vacuum ground-state path. Within this framework, the key step is the construction of the level-k operator sequences out of those at level-1 by the action of a new type of operators. These actions of operators on operators turn out to have a path interpretation: these paths are precisely the finitized RSOS paths related to the unitary minimal models M(k+1,k+2). We thus unravel -- at the level of the path representation of the states --, a direct factorization into a k=1 spinon part times a RSOS factor. It is also pointed out that since there are two fermionic forms describing these finite RSOS paths, the resulting fermionic su(2)_k characters arise in two versions. Finally, the relation between the present construction and the Nagoya spectral decomposition of the path space is sketched.

description: We present an analytical formalism for the description of Blazhko RR Lyrae light curves in which employ a treatment for the amplitude and frequency modulations in a manner similar to the theory of electronic signal transmitting. We assume monoperiodic RR Lyrae light curves as carrier waves and modulate their amplitude (AM), frequency (FM), phase (PM), and as a general case we discuss simultaneous AM and FM. The main advantages of this handling are the following: (i) The mathematical formalism naturally explains numerous light curve characteristics found in Blazhko RR Lyrae stars such as mean brightness variations, complicated envelope curves, non-sinusoidal frequency variations. (ii) Our description also explains properties of the Fourier spectra such as apparent higher-order multiplets, amplitude distribution of the side peaks, the appearance of the modulation frequency itself and its harmonics. In addition, comparing to the traditional method, our light curve solutions reduce the number of necessary parameters. This formalism can be applied to any type of modulated light curves, not just for Blazhko RR Lyrae stars.

What pp SUSY limits mean for future $e^+e^−$ colliders

Year: 2021

description: 14th Annual Meeting of the Helmholtz Alliance "Physics at the Terascale", Hamburg, Germany, 23 Nov 2021 - 24 Nov 2021
description: It is well-known that $e^+e^−$ colliders have the power to with certainty exclude or discover any SUSY model that predicts a Next to lightest SUSY particle (an NLSP) that has a mass up to slightly below the half the centre-of-mass energy of the collider. Here, we present an estimation of the power of present and future hadron colliders to extend the reach of searches for SUSY, with particular emphasis whether it can be claimed that either discovery or exclusion is {\it guaranteed} in a region of LSP and NLSP masses - no set of values of the other SUSY could change the conclusion. A scan over SUSY parameter space was done, only requiring that the NLSP was a bosino - the hardest case - with mass not larger than a few TeV. The mass-spectrum, cross-sections and decay branching ratios found in this region were confronted with projections of sensitivity at future hadron colliders. In our conclusions we weigh in the maturity of the analysis the projections are based upon. The conclusion is that although future hadron colliders have a large discovery-reach, i.e. potential to discover {\it some} SUSY model, hardly any models with low-to-medium LSP-NLSP mass-differences can be excluded with certainty. The models that are expected to be excluded/discovered are, on one hand, those with mass-differences larger than those allowed by models with GUT-scale M1-M2 unification, and on the other hand, a tiny region where the mass-difference is so small that the NLSP decays in the tracking volume of the detectors. Excluding the latter possibility does not, however, allow to exclude the possibility of a Wino or Higgsino LSP: at any value of the LSP mass, we could identify models where the NLSP lifetime would be too short for a signal to be seen.

description: Aerial suspension is an important process to link potential sources of particles to atmospheric transport. For contaminants like radioactive particles, pesticides or spores aerial suspension is especially relevant. We present a method that can visually quantify the suspension potential of particles in an idealized surface atmosphere system. The suspension potential of an airflow was assessed by quantifying fluorescent microplastic particles on a glass plate and exposing them to an incrementally increasing erosive wind force. In this first application of the method, we demonstrate its utility across a range of microplastic particles with regard to shape, size and polymer composition, and to detect two distinct regimes with different suspension rates. It can yield statistically robust estimates for the suspension potential of suspended fractions of up to 2500 particles at a mean areal number density of 2.6 particles per mm2. The mean wind speed at 2.7 cm height reached up to 5.2 ms−1 with a corresponding friction velocity of 0.51 ms−1. Copyright © 2021 American Association for Aerosol Research

description: Biofuel combustion is an important source of particulate light absorbing organic carbon (OC), also known as brown carbon (BrC). We applied spectrophotometry to characterize methanol-extracted BrC from emission tests of “real-world” biofuel combustion in India and Malawi, including wood stoves (‘traditional’, ‘improved’ and ‘chimney’) and artisanal charcoal kilns. Average mass absorption coefficient (MACbulk,λ) of extracted BrC was highest for ‘traditional’, followed by ‘improved’, ‘chimney’, and ‘charcoal’, at near-ultraviolet to blue wavelengths, with this order reversed for BrC absorption Angstrom exponent (AAE). MACbulk,λ in UV wavelengths was positively correlated with the elemental carbon to organic aerosol ratio (EC/OA), though the correlation was weaker than that observed in laboratory cookstove samples. BrC imaginary refractive indices (k) were anti-correlated with wavelength dependence (w), thus less wavelength dependent BrC had higher light absorptivity. MACbulk,λ correlated with the fraction of OC evolving at higher temperature steps in thermo-optical analysis, consistent with a link between BrC absorptivity and OC volatility, and suggesting that BrC absorption may be parameterized using existing OC data. Modeling analyses showed that BrC makes a strong contribution to overall absorption (average of 48% to 80% at 365 nm), and a strong negative correlation between EC/OA and the relative contribution of BrC to total aerosol (BrC + BC) light absorption; the latter trend is dominated by quantity versus optical properties of BrC. The estimated direct radiative effect of BrC is approximately equal to that of BC for biofuel combustion emissions in India, highlighting the importance of BrC in the climate energy budget.
Exact two-time correlation and response functions in the one-dimensional coagulation-diffusion process by the empty-interval-particle method

description: The one-dimensional coagulation-diffusion process describes the strongly fluctuating dynamics of particles, freely hopping between the nearest-neighbour sites of a chain such that one of them disappears with probability 1 if two particles meet. The exact two-time correlation and response function in the one-dimensional coagulation-diffusion process are derived from the empty-interval-particle method. The main quantity is the conditional probability of finding an empty interval of n consecutive sites, if at distance d a site is occupied by a particle. Closed equations of motion are derived such that the probabilities needed for the calculation of correlators and responses, respectively, are distinguished by different initial and boundary conditions. In this way, the dynamical scaling of these two-time observables is analysed in the longtime ageing regime. A new generalised fluctuation-dissipation ratio with an universal and finite limit is proposed.

description: The purpose of this study is to understand the effect of essential surgical design parameters on collateral and cruciate ligaments behavior for a Bone-Patellar-Tendon-Bone (BPTB) anterior cruciate ligament reconstruction (ACL-R) surgery. A parametric finite element model of biomechanical experiments depicting the ACL-R surgery associated with a global sensitivity analysis was adopted in this work. The model parameters were six intraoperative variables, two-quadrant coordinates of femoral tunnel placement, femoral tunnel sagittal and coronal angles, graft pretension, and the joint angle at which the BPTB graft is tensioned (fixation angle). Our results indicated that cruciate ligaments (posterior cruciate ligament (PCL) and graft) were mainly sensitive to graft pretension (23%), femoral tunnel sites (56%), and the angle at which the surgeon decided to fix the graft (14%). The collateral ligaments (medial and lateral) were also affected by the same set of surgical parameters as the cruciate ligaments except for graft pretension. The output data of this study may help to identify a better role for the ACL-R intraoperative variables in optimizing the knee joint ligaments’ postsurgical functionality.
Evidence for the neuromotor simulation hypothesis in action prediction
Creators: name: Mulligan, Desmond
Publisher: name: University of British Columbia
Year: 2016

description: The overarching aim of this thesis was to further understand the processes and internal representations involved in predicting action outcomes, by manipulating information sources during learning and prediction. Growing evidence suggests that the human motor system is activated during action observation, such that motor representations are invoked, through simulative processes that help facilitate an understanding of the unfolding action. In this work, we employed a design that manipulated visual and motor influences during learning and prediction, to try to understand; a) the types of internal representations acquired during practice, and b) how, and under what conditions, these representations are activated during prediction, and, more specifically, the conditions under which action prediction can come about through either visual- or motor-based mechanisms. In Experiment 1 we found that a group that learned to throw darts without vision of the action performed as well, on a post-practice prediction task, as a group that practiced with full vision. These results suggested that motor practice was key to learning the skill, and vision appeared not to be important. However, it was unclear whether motor representations were formed during practice, and then simulated during action prediction, or that visual representations were formed during practice and later compared to the visual input through a perceptual matching process. In Experiment 2 we found that an incongruent secondary motor task interfered with the prediction process, reducing prediction accuracy of experts to the level of a novice with no motor experience with the task. These results implied that motor system activation was responsible for prediction accuracy, by simulating established motor representations within the observer. In Experiment 3, results showed that a group that trained physically, significantly improved their prediction accuracy, but performed at a pre-training level while engaging in an effector-specific, incongruent secondary motor task during prediction. In contrast, a perceptually trained group also significantly improved their prediction accuracy after practice, but did not exhibit any modulation of prediction accuracy while engaged in the secondary motor task. These results suggest that action prediction can be mediated by different processes, one motor-based and one visually-based, depending on type of training.

description: The energy-momentum conservation laws for general reduced-fluid (e.g., gyrofluid) models are derived by Noether method from a general reduced variational principle. The reduced canonical energy-momentum tensor (which is explicitly asymmetric and has the Minkowski form) exhibits polarization and magnetization effects associated with dynamical reduction. In particular, the asymmetry in the reduced canonical momentum-stress tensor produces a non-vanishing reduced intrinsic torque that can drive spontaneous toroidal rotation in axisymmetric tokamak plasmas.

title: sRNARFTarget: a machine learning-based approach for sRNA target prediction
Creators: name: Naskulwar, Kratika
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Bacterial small regulatory RNAs (sRNAs) play a vital role in the regulation of gene expression in bacteria. sRNAs regulate gene expression by interacting with mRNAs or proteins. Bacterial sRNAs are involved in various processes, such as environmental stress response, metabolism, and virulence. We need to identify the mRNAs and/or proteins that these sRNAs interact with, to understand the functional roles of sRNAs. These mRNAs or proteins are called targets of the sRNAs. There are several computational tools available for sRNA target prediction; however, these tools have a high number of false positives, and the most accurate tool requires sRNA sequence conservation across bacteria. As a result of this research project, a machine-learning-based method (sRNARFTarget) for sRNA target prediction applicable to any bacterium or sRNA has been developed. In this thesis, we show that sRNARFTarget substantially outperforms current non-comparative genomics-based methods in terms of running time and ranking of true interactions.

description: Research on secondhand electronic cigarette (ECIG) aerosol exposure using aerosol monitors has demonstrated that ECIG use can generate high concentrations of particulate matter (PM) and impact indoor air quality. However, quantifying indoor air PM concentrations using real-time optical monitors with on-site calibration specifically for different PM exposures has not been established. Therefore, the ECIG aerosol filter correction factors were calculated for different PM sizes (PM1, PM2.5, and PM10) and different aerosol optical monitors, the MiniWRAS, pDR, and SidePak. ECIG aerosol generation was achieved using five ECIGs representing three ECIG types, disposable, pod-mod, and box mod. The aerosol size distribution by mass was measured for the five ECIGs during PM generation. Compared to the discrete filter measurements, the MiniWRAS performed the best when the concentrations were low, followed by the pDR and SidePak. The average PM concentrations and correction factor ranges for the different ECIGs were 323-1,775 µg/m3 and 0.64-6.01 for the MiniWRAS, 1,388-13,365 µg/m3 and 0.41-0.80 for the pDR, and 4,632-55,339 µg/m3 and 0.13-0.20 for the SidePak, respectively. The mass median diameter ranged from 0.41 and 0.62 µm, and most particles generated from the ECIGs were smaller than 1 µm. This study demonstrates that aerosol size distribution varies between ECIGs. Likewise, the correction factors developed for the real-time aerosol monitors are specific to the ECIG used. Thus, these data can help improve ECIG aerosol exposure measurement accuracy.

description: Link prediction is an open problem in the complex network, which attracts much research interest currently. However, little attention has been paid to the relation between network structure and the performance of prediction methods. In order to fill this vital gap, we try to understand how the network structure affects the performance of link prediction methods in the view of clustering. Our experiments on both synthetic and real-world networks show that as the clustering grows, the precision of these methods could be improved remarkably, while for the sparse and weakly clustered network, they perform poorly. We explain this through the distinguishment caused by increased clustering between the score distribution of positive and negative instances. Our finding also sheds light on the problem of how to select appropriate approaches for different networks with various densities and clusterings.

description: We present in this Letter experimental results on the bidimensional flow field around a cylinder penetrating into dense granular matter together with drag force measurements. A hydrodynamic model based on extended kinetic theory for dense granular flow reproduces well the flow localization close to the cylinder and the corresponding scalings of the drag force, which is found to not depend on velocity, but linearly on the pressure and on the cylinder diameter and weakly on the grain size. Such a regime is found to be valid at a low enough "granular" Reynolds number.

We use generalized factorization and $SU(3)_F$ symmetry to relate such modes to correspondent $B$ decay channels. We discuss the feasibility of the measurements in the various channels, stressing the importance of comparing different determinations of $β_s$ in view of the hints of new physics effects (NP) recently emerged in the $B_s$ sector. Finally, adopting a general parametrization of NP contributions to the decay amplitudes, we discuss how to experimentally constrain new physics parameters.

description: The purpose of this study is to understand the effect of essential surgical design parameters on collateral and cruciate ligaments behavior for a Bone-Patellar-Tendon-Bone (BPTB) anterior cruciate ligament reconstruction (ACL-R) surgery. A parametric finite element model of biomechanical experiments depicting the ACL-R surgery associated with a global sensitivity analysis was adopted in this work. The model parameters were six intraoperative variables, two-quadrant coordinates of femoral tunnel placement, femoral tunnel sagittal and coronal angles, graft pretension, and the joint angle at which the BPTB graft is tensioned (fixation angle). Our results indicated that cruciate ligaments (posterior cruciate ligament (PCL) and graft) were mainly sensitive to graft pretension (23%), femoral tunnel sites (56%), and the angle at which the surgeon decided to fix the graft (14%). The collateral ligaments (medial and lateral) were also affected by the same set of surgical parameters as the cruciate ligaments except for graft pretension. The output data of this study may help to identify a better role for the ACL-R intraoperative variables in optimizing the knee joint ligaments’ postsurgical functionality.

description: Introduction: Unilateral posterior crossbite with functional shift is a relatively common condition. Spontaneous correction occurs in ~17% of the cases and mixed dentition slow maxillary expansion demonstrated 84% stability in permanent dentition. The purpose of this study was to evaluate palatal symmetry, dimensions and molar angulation changes following slow maxillary expansion during the mixed dentition compared to untreated controls. Methodology: 30 subjects treated with a Haas-type slow maxillary expansion appliance for unilateral posterior crossbite with a functional shift were compared to 30 control subjects matched for dental age, gender and dental classification. Records were taken at T1= before expansion and at T2= after expansion. Palatal width, surface area, volume and molar angulations measured on digitized models. Palatal surface area and volume divided into anterior, middle and posterior parts then split into crossbite and non-crossbite sides by the midpalatal plane to measure symmetry. Student’s t-test assessed the differences between the groups. Results: Mean intercanine width increase from T1-T2 was 4.65mm, while the intermolar width increase was 4.76mm. The mean increase in the surface area from T1-T2 was 127.05 mm2, while for the controls it was 10.35mm2. The mean palatal volume increased by 927.55mm3 for the treated sample while for the controls it increased by 159.89 mm3. At T1, significant differences between the crossbite and noncrossbite sides were only present in the anterior halves of the controls in surface area and volume. At T2, difference was only present in the surface area of the treated sample in the middle halves. The first permanent molar showed an increase in the buccal and distal inclination after treatment while in controls it showed a decrease. The increase in the buccal inclination was greater on the treated crossbite side. Conclusions: Expansion across the canines and first permanent molars was almost similar. Palate was symmetric before expansion and became asymmetric after expansion in the middle halves. The first permanent molars tipped buccally and distally following expansion with significant tipping on the crossbite side buccally. Our method of molar angle measurement does not require radiation and allows measurement of each individual molar’s angulation.

description: The method based on microscopic theory of nuclear reactions has been applied for the analysis of parity violating effects in a few-body systems. Different parity violating and parity conserving asymmetries and their dependence on neutron energy have been estimated for $n + ^3He \rightarrow ^3H + p$ reaction. The estimated effects are in a good agreement with available exact calculations.

description: Is there a low-density region ('gap') between water and a hydrophobic surface? Previous X-ray/neutron reflectivity results have been inconsistent because the effect (if any) is sub-resolution for the surfaces studied. We have used X-ray reflectivity to probe the interface between water and more hydrophobic smooth surfaces. The depleted region width increases with contact angle and becomes larger than the resolution, allowing definitive measurements. Large fluctuations are predicted at this interface; however, we find that their contribution to the interface roughness is too small to measure.

description: A variety of phenomena connected with the formation of a dinuclear complex is observed in the heavy ion collisions at low energies. The dinuclear system model allows us to analyze the experimental data and to interpret them by comparison of the partial capture, fusion and evaporation residue cross sections measured for the different reactions leading to the same compound nucleus. The comparison of theoretical and experimental values of the mass and angular distributions of the reaction products gives us a detailed information about reaction mechanism forming the observed yields. The observed very small cross sections of the evaporation residues may be explained by the strong fusion hindrance and/or instability of the heated and rotating compound nucleus and smallness of its survival probability. The fusion hindrance arises due to competition between complete fusion and quasifission while the smallness of survival probability is connected with the decrease of the fission barrier at large excitation energy and angular momentum of compound nucleus.

description: We review the infrared behavior of interacting bosons at zero temperature. After a brief discussion of the Bogoliubov approximation and the breakdown of perturbation theory due to infrared divergences, we present two approaches that are free of infrared divergences -- Popov's hydrodynamic theory and the non-perturbative renormalization group -- and allow us to obtain the exact infrared behavior of the correlation functions. We also point out the connection between the infrared behavior in the superfluid phase and the critical behavior at the superfluid--Mott-insulator transition in the Bose-Hubbard model.
