description: Novel magnetic CoFe2O4-embedded MIL-101(Cr) with tetramethylammonium hydroxide (CoFe2O4/MIL-101T) was prepared through the facile hydrothermal method. Tetramethylammonium hydroxide acts as a template molecule and avoids the recrystallisation of terephthalic acid. The material was applied as the adsorbent in the magnetic solid-phase extraction (MSPE) process coupled with high-performance liquid chromatography to detect the five flame retardants in environmental water samples. Several parameters affecting MSPE efficiency were systematically investigated, such as MIL-101T content, material amount, desorption solvents, adsorption time, solution pH, theoretical maximum enrichment factor (EFmax) and the reusability. Under optimised conditions, good linearities were achieved for five flame retardants with correlation coefficients R2 > 0.9961. The limits of detections for analytes at the signal-to-noise ratio of three were 0.013–0.071 μg·L−1. This method was applied to the analysis of tap, pond, lake and river waters. The recoveries were in the range of 81.5 ± 3.2–107.0 ± 2.3% with the relative standard deviations ranging from 0.11% to 8.66% in four real water samples. The adsorption mechanism was the hydrophobic interaction between the material and the analytes besides pore adsorption action of the material.
Decentralized social media for scientists: Big Brother doesn't have to boss you around

description: The resilience of networks, such as the electrical grid or communication networks, requires to avoid bottleneck nodes whose failure compromises the whole network. This is true of the physical infrastructure, but also of the software and governance architecture of networks. Historically, the world wide web has developed as a decentralised network, defined by a communication protocol, but made of independently hosted websites connected by hyperlinks. Social media such as Twitter, however, have developed under a centralised governance, making their users dependent on central decisions. The takeover of Twitter by Elon Musk has brought increased interest for WWW-like alternatives, which are made of a myriad of independently-run but interconnected services. 

The Fediverse is the global network that all these services form together. In this talk, I will give both a global perspective on the organisation of this decentralised network and give a flavour of what a user may experience when using it, with an attention on the interests of a scientific researcher.

 

This talk is not be about why it matters but rather showing what the differences are, for you to decide what is best to do or not to do.

Size-waiting-time correlations in pulsar glitches

description: Few statistically compelling correlations are found in pulsar timing data between the size of a rotational glitch and the time to the preceding glitch (backward waiting time) or the succeeding glitch (forward waiting time), except for a strong correlation between sizes and forward waiting times in PSR J0537-6910. This situation is counterintuitive, if glitches are threshold-triggered events, as in standard theories (e.g. starquakes, superfluid vortex avalanches). Here it is shown that the lack of correlation emerges naturally, when a threshold trigger is combined with secular stellar braking slower than a critical, calculable rate. The Pearson and Spearman correlation coefficients are computed and interpreted within the framework of a state-dependent Poisson process. Specific, falsifiable predictions are made regarding what objects currently targeted by long-term timing campaigns should develop strong size-waiting-time correlations, as more data are collected in the future.

Stellar surveys

description: Over the last decades, rapid advances in technology and the resulting increasing number of large-scale photometric and spectroscopic surveys have helped to propel astronomy into a new data-rich era. During the past few years, our working group has exploited the available wealth of data for the study of chemically peculiar (CP) stars of the upper main sequence. The main focus has been on the analysis of the Ap/CP2 stars and the He-peculiar stars, which are often grouped together under the term of magnetic CP (mCP) stars. Due to the influence of a strong and organized magnetic field on the diffusion processes, mCP stars show a non-uniform distribution of chemical elements (chemical spots or belts) on their surfaces. Flux is redistributed in these spots, which results in strictly periodic light and spectral variations with the rotation period, which are well understood in terms of the oblique-rotator model in which the magnetic axis is oblique to the rotation axis. According to convention, photometrically variable mCP stars are referred to as alpha2 Canum Venaticorum (ACV) variables. In this talk, we review the capabilities of the following ground-based photometric surveys: - All Sky Automated Survey (ASAS-3) - Asteroid Terrestrial-impact Last Alert System (ATLAS) - The Kilodegree Extremely Little Telescope (KELT) - The Multi-site All-Sky CAmeRA (MASCARA) - Wide Angle Search for Planets (WASP) - The Zwicky Transient Facility (ZTF) Our data archival techniques and time series analysis methods can be applied to any other group of OBA stars. We furthermore describe our data analysis techniques and time series analysis, which can be applied to any other group of OBA stars. We also detail our efforts at discovering and classifying new mCP stars in the spectroscopic archives of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) using an automated procedure (Richard O. Gray's MKCLASS code) and manual classification. This approach can also be applied to the whole group of OBA stars.

description: We use full sky simulations, including the effects of foreground contamination and removal, to explore multi-tracer synergies between a SKA-like 21cm intensity mapping survey and a LSST-like photometric galaxy redshift survey. In particular we study ratios of auto and cross-correlations between the two tracers as estimators of the ratio of their biases, a quantity that should benefit considerably from the cosmic variance cancellation of the multi-tracer approach. We show how well we should be able to measure the bias ratio on very large scales (down to $\ell \sim 3$), which is crucial to measure primordial non-Gaussianity and general relativistic effects on large scale structure. We find that, in the absence of foregrounds but with realistic noise levels of such surveys, the multi-tracer estimators are able to improve on the sensitivity of a cosmic-variance contaminated measurement by a factor of $2-4$. When foregrounds are included, estimators using the 21cm auto-correlation become biased. However, we show that cross-correlation estimators are immune to this and do not incur in any significant penalty in terms of sensitivity from discarding the auto-correlation data. However, the loss of long-wavelength radial modes caused by foreground removal in combination with the low redshift resolution of photometric surveys, reduces the sensitivity of the multi-tracer estimator, albeit still better than the cosmic variance contaminated scenario even in the noise free case. Finally we explore different alternative avenues to avoid this problem.

Frenkel Excitons in Random Systems With Correlated Gaussian Disorder

Publisher: name: arXiv
Year: 1995
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: Optical absorption spectra of Frenkel excitons in random one-dimensional systems are presented. Two models of inhomogeneous broadening, arising from a Gaussian distribution of on-site energies, are considered. In one case the on-site energies are uncorrelated variables whereas in the second model the on-site energies are pairwise correlated (dimers). We observe a red shift and a broadening of the absorption line on increasing the width of the Gaussian distribution. In the two cases we find that the shift is the same, within our numerical accuracy, whereas the broadening is larger when dimers are introduced. The increase of the width of the Gaussian distribution leads to larger differences between uncorrelated and correlated disordered models. We suggest that this higher broadening is due to stronger scattering effects from dimers.

description: The outcome of the SAMPLE Experiment suggests that the strange-quark contribution to the nucleon magnetic moment, G_M^s(0), may be greater than zero. This result is very difficult to reconcile with expectations based on the successful baryon magnetic-moment phenomenology of the constituent quark model. We show that careful consideration of chiral symmetry reveals some rather unexpected properties of QCD. In particular, it is found that the valence u-quark contribution to the magnetic moment of the neutron can differ by more than 50% from its contribution to the Xi^0 magnetic moment. This hitherto unforeseen result leads to the value G_M^s(0) = -0.16 +/- 0.18 with a systematic error, arising from the relatively large strange quark mass used in existing lattice calculations, that would tend to shift G_M^s(0) towards small positive values.

description: Weak boson fusion is a copious source of intermediate mass Higgs bosons at the LHC. The additional very energetic forward jets in these events provide for powerful background suppression tools. We analyze the $H \to ττ$ decay mode for the Standard Model Higgs boson. A parton level analysis of the dominant physics backgrounds (mainly $Z \to ττ$ and Drell-Yan production of $τ$'s) and of reducible backgrounds (from $W+$ jet and $b\bar{b}$ production in association with two jets and subsequent leptonic decays) demonstrates that this channel allows the observation of $H \to ττ$ in a low background environment, yielding a significant Higgs signal with an integrated luminosity of about 30 fb$^{-1}$. The weak boson fusion process thus allows direct measurement of the $Hττ$ coupling.

description: A family of degenerate domain wall configurations, partially preserving supersymmetry, is discussed in a generalized Wess-Zumino model with two scalar superfields. We establish some general features inherent to the models with continuously degenerate domain walls. For instance, for purely real trajectories additional "integrals of motion" exist. The solution for the profile of the scalar fields for any wall belonging to the family is found in quadratures for arbitrary ratio of the coupling constants. For a special value of this ratio the solution family is obtained explicitly in terms of elementary functions. We also discuss the threshold amplitudes for multiparticle production generated by these solutions. New unexpected nullifications of the threshold amplitudes are found.

Photospheric response to a flare

description: Flares produce sudden and permanent changes in the horizontal photospheric magnetic field. In particular flares generally produce increased magnetic shear in the photospheric field along the neutral line. Recent observations show also that flares can produce sudden photospheric motion. We present a model for the observed changes as the response of the photosphere to a large-amplitude shear Alfvén wave propagating down from the corona on either side of the neutral line. The Alfvénic front is assumed to impact the photosphere close to the neutral line first, and then successively further away with time, such that the line of impact coincides with the flare ribbon. The wave introduces magnetic shear and velocity shear. The magnetic shear introduced at the photosphere has the same sign on either side of the neutral line, while the velocity shear has the opposite sign. We discuss the possibility that this process is responsible for particle acceleration in flares.

description: MitraClip transcatheter edge-to-edge repair is
used to treat mitral regurgitation (MR). While MR is
reduced, diastolic left ventricular flows are altered. An
in vitro left heart simulator was used to assess a porcine
mitral valve in the native, MR, and MR plus MitraClip cases.
Velocity, vorticity, and Reynolds shear stress (RSS) were
quantified by particle image velocimetry. Peak velocity
increased from 1.20 m/s for native to 1.30 m/s with MR.
With MitraClip, two divergent jets of 1.18 and 0.61 m/s
emerged. Higher vorticity was observed with MR than native and lessened with MitraClip. MitraClip resulted in shear layer formation and downstream vortex formation. Native RSS decreased from 33 Pa in acceleration to 29 Pa at peak flow, then increased to 31 Pa with deceleration. MR RSS increased from 27 Pa in acceleration to 40 Pa at peak flow to
59 Pa during deceleration. MitraClip RSS increased from 79 Pa in acceleration to 162 Pa during peak flow, then decreased to 45 Pa during deceleration. After MitraClip, two divergent jets of reduced velocity emerged, accompanied by shear layers and recirculation. Chaotic flow developed, resulting in elevated RSS magnitude and coverage. Findings help understand
consequences of MitraClip on left ventricular flow
dynamics.

description: We study string fragmentation in high multiplicity proton-proton collisions in a model where the string tension fluctuates. These fluctuations produce exponential pion spectra which are fitted to the transverse momentum distributions of charged particles for different multiplicities. For each multiplicity the so obtained hadronic slope parameter defines the magnitude of the string fluctuations which in turn determines the produced ratio of strange to light quarks. PYTHIA string decay simulations are used to convert each ratio of strange to light quarks to the appropriate ratio of strange hadrons to pions.

description: We present an analysis of the impact of spiral density waves (DWs) on the radial and surface density distributions of supernovae (SNe) in host galaxies with different arm classes. We use a well-defined sample of 269 relatively nearby, low-inclination, morphologically non-disturbed and unbarred Sa-Sc galaxies from the Sloan Digital Sky Survey, hosting 333 SNe. Only for core-collapse (CC) SNe, a significant difference appears when comparing their R25-normalized radial distributions in long-armed grand-design (LGD) versus non-GD (NGD) hosts, with that in LGD galaxies being marginally inconsistent with an exponential profile, while SNe Ia exhibit exponential surface density profiles regardless of the arm class. Using a smaller sample of LGD galaxies with estimated corotation radii (Rc), we show that the Rc-normalized surface density distribution of CC SNe indicates a dip at corotation. Although not statistically significant, the high CC SNe surface density just inside and outside corotation may be the sign of triggered massive star formation by the DWs. Our results may, if confirmed with larger samples, support the large-scale shock scenario induced by spiral DWs in LGD galaxies, which predicts a higher star formation efficiency around the shock fronts, avoiding the corotation region.

description: At sufficiently high temperature and density, quantum chromodynamics (QCD) is expected to undergo a phase transition from the confined phase to the quark-gluon plasma phase. In the Lagrangian lattice formulation the Monte Carlo method works well for QCD at finite temperature, however, it breaks down at finite chemical potential. We develop a Hamiltonian approach to lattice QCD at finite chemical potential and solve it in the case of free quarks and in the strong coupling limit. At zero temperature, we calculate the vacuum energy, chiral condensate, quark number density and its susceptibility, as well as mass of the pseudoscalar, vector mesons and nucleon. We find that the chiral phase transition is of first order, and the critical chemical potential is $μ_C =m_{dyn}^{(0)}$ (dynamical quark mass at $μ=0$). This is consistent with $μ_C \approx M_N^{(0)}/3$ (where $M_N^{(0)}$ is the nucleon mass at $μ=0$).

description: Theoretical analyses of the random energy model with only two states and its extension with a hierarchy of only two levels show that these models reproduce out-of-equilibrium phenomena observed in experiments of glassy materials; the rejuvenation effect (the chaos effect), i.e. the abrupt jump and subsequent relaxation of the out-of-phase susceptibility as if the system rejuvenates when the temperature is lowered, and the power-law relaxation of the two-time correlation function. Our results suggest that also in an assembly of small systems with relaxation times distributed broadly some of these interesting out-of-equilibrium phenomena can be observed.

Domain Walls and Theta Dependence in QCD with an Effective Lagrangian Approach

description: We suggest an anomalous effective Lagrangian which reproduces the anomalous conformal and chiral Ward identities and topological charge quantization in QCD. It is shown that the large N_c Di Vecchia-Veneziano-Witten effective chiral Lagrangian is locally recovered from our results, along with 1/N_c corrections, after integrating out the heavy "glueball" fields. All dimensionful parameters in our scheme are fixed in terms of the quark and gluon condensates and quark masses. We argue that for a certain range of parameters, metastable vacua appear which are separated from the true vacuum of lowest energy by domain walls. The surface tension of the wall is estimated, and the dynamics of the wall is discussed. The U(1) problem and the physics of the pseudo-goldstone bosons at different theta angles are addressed within the effective Lagrangian approach. Implications for axion physics, heavy ion collisions and the development of the early Universe during the QCD epoch are discussed.

description: This presentation summarized results from a proof-of-concept LiDAR survey and data processing, as well as long-term radon concentration monitoring in the Bozkov dolimite caves.

These caves are situated in a Lugian region, in the area geologically called the Krkonoše-Jizera crystalline unit. Carbonate rocks occur in discontinuous streaks and lenses in this area. The lens in which the Bozkov caves were formed is 300 m in length and has a maximum width of about 150 m. The cave is permeated by calcareous and siliceous dolomite lenses from the Silurian age, surrounded by phyletic shales. The bedrock below the underground areas is the major source of radon. The environment of caves is typically characterized by 100% humidity, and the number of aerosol particles is around 102 times lower than outside (but the number of free ions is higher). The concentration of radon in the Bozkov dolomite caves may reach levels tens of thousands Bq/m3. The methodology for effective dose from radon estimation for cave guides is based on integral radon activity concentration measurement cV,Rn (integral RAMARN detectors) and evidence of working hours spent in the underground. Continuous radon measurement has been taking place here since 2003, and the measured concentrations form a complete set of data that was processed for the purpose of estimating and predicting movements in the earth's crust.

Monitoring by integral monitors at basic communication (ventilation) nodes in the cave can also show how in-outside temperature changes affect air mass movements in a given cave, if we have a cave model available. 2 years ago, the continuous measurement was extended to a total of 7 positions in the cave system, and the measurement results allow a better understanding of the cave ventilation. The presented contribution introduces 3D cave system visualization (LiDAR technology), embedded in a geological environment following the results of in situ gamma spectrometry (surface above the cave) and continuous radon activity concentration measured by a set of TSR probes.
Constraining the population of intermediate mass black holes by gamma-ray data of the Fornax cluster

description: Recent studies of merging black holes suggest that the cosmological mass fraction of primordial black holes (PBHs) is not completely negligible. The mass of a PBH can be as massive as an intermediate mass black hole (IMBH). In this article, we assume that dark matter particles are thermal relic particles and they can self-annihilate. The dark matter around an IMBH may have formed a density spike so that the rate of dark matter annihilation would be greatly enhanced. Using the gamma-ray data of the Fornax cluster and assuming merging events in the cluster are not important, we show that the amount of IMBHs (including PBHs) is very sub-dominant compared with the amount of baryons and dark matter. The upper limit on the IMBH-to-baryon ratio is $\sim 7\times 10^{-4}$ for $m_{\rm DM} \le 10$ TeV.

ASTM F2245-16c

description: The paper studied the strength and deformation characteristics of a composite wing of a two-seater seaplane to get the certificate of airworthiness, which static testing is indispensable. The primary wing structure component includes upper and lower skins, leading edge, trailing edge, a root rib, and main spar. The main purpose of static testing is to examine the bending strength of the wing. The deformation of the wing and measured strain data were collected by a computer. The testing results show good agreement with the FE analysis results, and the bending strength of the wing is strong enough to support the limit loads (the maximum loads to the expected in-service) without detrimental and permanent deformation and without failure for at least 3s under the ultimate loads (limit loads multiplied by prescribed factors of safety), which meets the requirement of ASTM F2245-16c (Standard Specification for Design and Performance of a Light Sport Airplane).

description: In a recent paper Yang and Bodek extracted the free neutron structure function at large x by extrapolating the density dependence of the nuclear EMC ratios to the deuteron. We clarify why this approach is ill-defined for light nuclei, and introduces a large theoretical bias into the extraction of F_2n at large x.

First-principles theory of ferroelectric phase transitions for perovskites: The case of BaTiO3

description: We carry out a completely first-principles study of the ferroelectric phase transitions in BaTiO$_3$. Our approach takes advantage of two features of these transitions: the structural changes are small, and only low-energy distortions are important. Based on these observations, we make systematically improvable approximations which enable the parameterization of the complicated energy surface. The parameters are determined from first-principles total-energy calculations using ultra-soft pseudopotentials and a preconditioned conjugate-gradient scheme. The resulting effective Hamiltonian is then solved by Monte Carlo simulation. The calculated phase sequence, transition temperatures, latent heats, and spontaneous polarizations are all in good agreement with experiment. We find the transitions to be intermediate between order-disorder and displacive character. We find all three phase transitions to be of first order. The roles of different interactions are discussed.

description: Understanding the mechanisms responsible for the formation and growth of FtsZ polymers and their subsequent formation of the $Z$-ring is important for gaining insight into the cell division in prokaryotic cells. In this work, we present a minimal stochastic model that qualitatively reproduces {\it in vitro} observations of polymerization, formation of dynamic contractile ring that is stable for a long time and depolymerization shown by FtsZ polymer filaments. In this stochastic model, we explore different mechanisms for ring breaking and hydrolysis. In addition to hydrolysis, which is known to regulate the dynamics of other tubulin polymers like microtubules, we find that the presence of the ring allows for an additional mechanism for regulating the dynamics of FtsZ polymers. Ring breaking dynamics in the presence of hydrolysis naturally induce rescue and catastrophe events in this model irrespective of the mechanism of hydrolysis.

Large-scale Structure from Quantum Fluctuations in the Early Universe

description: A better understanding of the formation of large-scale structure in the Universe is arguably the most pressing question in cosmology. The most compelling and promising theoretical paradigm, Inflation + Cold Dark Matter, holds that the density inhomogeneities that seeded the formation of structure in the Universe originated from quantum fluctuations arising during inflation and that the bulk of the dark matter exists as slowing moving elementary particles (`cold dark matter') left over from the earliest, fiery moments. Large redshift surveys (such as the SDSS and 2dF) and high-resolution measurements of CBR anisotropy (to be made by the MAP and Planck Surveyor satellites) have the potential to decisively test Inflation + Cold Dark Matter and to open a window to the very early Universe and fundamental physics.
