Assessment and Diagnostic Standards of Apraxia of Speech in Chinese-Speaking Adults and Children: A Scoping Review
Authors: Wong Eddy Chun Ho , Wong Min Ney , Velleman Shelley L.
Published: November 2022

Purpose:

Apraxia of speech (AOS) and childhood apraxia of speech (CAS) are motor-based speech disorders that have been well studied in Indo-European languages. There is limited understanding of these disorders in speakers of Sino-Tibetan languages, such as Chinese. The purpose of this study is to review methods used in research studies for the assessment and diagnosis of AOS and CAS in Chinese speakers.

Method:

This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Articles with a focus on AOS or CAS in Chinese speakers were systematically searched in seven English and six Chinese databases. Three reviewers performed independent screening, data extraction, and quality assessment after obtaining 100% agreement on the prescreening exercise. A qualitative analysis was conducted to rate the quality of diagnoses, ranging from high (Level I) to low (Level III), with Level IV assigned to studies for which the appropriate rating was unclear due to insufficient evidence.

Results:

Twenty-eight AOS articles and five CAS articles were identified. A variety of assessment and diagnostic methods were reported. No study of Chinese speakers with AOS or CAS received a rating of Level I. The highest level achieved was Level IIIa for both AOS and CAS studies.

Conclusions:

There is no reliable and valid test or method for the diagnosis of AOS or CAS in Chinese speakers. The current gold standard of diagnosis is based upon expert perceptual judgment. Further single-language and cross-linguistic investigations of AOS and CAS and the future development of assessment and diagnostic methods are recommended.

Context. Weak lensing and clustering statistics beyond two-point functions can capture non-Gaussian information about the matter density field, thereby improving the constraints on cosmological parameters relative to the mainstream methods based on correlation functions and power spectra.

Aims. This paper presents a cosmological analysis of the fourth data release of the Kilo Degree Survey based on the density split statistics, which measures the mean shear profiles around regions classified according to foreground densities. The latter is constructed from a bright galaxy sample, which we further split into red and blue samples, allowing us to probe their respective connection to the underlying dark matter density.

Methods. We used the state-of-the-art model of the density splitting statistics and validated its robustness against mock data infused with known systematic effects such as intrinsic galaxy alignment and baryonic feedback.

Results. After marginalising over the photometric redshift uncertainty and the residual shear calibration bias, we measured for the full KiDS-bright sample a structure growth parameter of $ S_8\equiv \sigma_8 \sqrt{\Omega_{\mathrm{m}}/0.3}=0.73^{+0.03}_{-0.02} $ that is competitive and consistent with two-point cosmic shear results, a matter density of Ωm = 0.27 ± 0.02, and a constant galaxy bias of b = 1.37 ± 0.10.

The prevalence of stunting in Indonesia was still high at 24.4% based on the 2021 Indonesian Nutritional Status Study, while at 20.9% in Central Java. Policymakers need to make quick and practical decisions to support the creation of an environment that empowers communities in stunting prevention. This current study aimed to describe the cause and effect of stunting and various applicable models of community empowerment in various regions of Indonesia to prevent stunting cases. This study used a qualitative method and focus group discussions (FDG) for data collection. It was conducted in mid-2022. The participants were the technical officers of the provincial government, National Population and Family Planning Board (BKKBN), non-government organizations, nutritionists, child health experts and academicians, as many as 2 participants from each organization selected by the purposive sampling method. The FGD results showed several good practices in some regions. One initiative to replicate is providing stunting prevention training for cadres and mothers of childbearing age and health promotion programs for prospective brides at least three months before marriage. Besides, forming a team for collecting data on prospective brides, and improving the existing recording system is required to reduce stunting prevalence.

Metabolisches Syndrom und gastrointestinale Krebsvorsorge
Authors: Scherübl Hans
Published: November 2022

Krebs und Herzkreislauferkrankungen sind die beiden führenden Todesursachen beim metabolischen Syndrom. Je mehr Komponenten des metabolischen Syndroms (MetS) vorliegen, umso stärker steigt das gastrointestinale (GI) Krebsrisiko. Das MetS ist ursächlich mit Adenokarzinomen der Speiseröhre, des Magens, des Pankreas, der Gallenwege, der Leber und des Dickdarms assoziiert. Das MetS erhöht die GI-Krebssterblichkeit bis zum 2,4-fachen. Bei adipösen MetS-Patienten kann die dauerhafte Gewichtsreduktion das GI-Krebsrisiko senken. Dem MetS vorzubeugen, es effektiv zu behandeln sowie regelmäßig an der GI-Krebsvorsorge teilzunehmen ist wichtig und verringert das Risiko, an GI-Karzinomen zu erkranken und daran zu versterben.

Published: November 2022

Background and study aims Percutaneous liver biopsy is traditionally done on the right lobe of the liver. Endoscopic ultrasound-guided liver biopsy (EUS-LB) can be performed on either the left or right lobe or as a combined bi-lobar biopsy. Earlier studies did not compare the benefit of bi-lobar biopsies to single-lobe biopsy for reaching a tissue diagnosis. The current study compared the degree of agreement of pathological diagnosis between the left lobe of the liver compared to right-lobe and with bi-lobar biopsy.

Patients and methods Fifty patients fulfilling the inclusion criteria were enrolled in the study. EUS-LB with a 22G core needle was performed separately on both the liver lobes. Three pathologists, who were blinded to the site of biopsy independently reviewed the liver biopsies. Sample adequacy, safety, and concordance of pathological diagnosis between left- and right-lobe biopsy of the liver were analyzed.

Results The pathological diagnosis was made in 96 % of patients. Specimen lengths from the left lobe and the right lobe were 2.31 ± 0.57 cm and 2.28 ± 0.69 cm, respectively (P = 0.476). The respective number of portal tracts were 11.84 ± 6.71 versus 9.58 ± 7.14; P = 0.106. Diagnosis between the two lobes showed substantial (κ = 0.830) concordance. Left-lobe (κ value 0.878) and right-lobe (κ = 0.903) biopsies showed no difference when compared with bi-lobar biopsies. Adverse events were observed in two patients, both of whom had biopsies of the right lobe.

Conclusions EUS-guided left-lobe liver biopsy is safer than right-lobe biopsy with similar diagnostic yield.
Fast fabrication and judgement of tip-enhanced Raman spectroscopy-active tips

Published: November 2022

The quality of the scanning tip is crucial for tip-enhanced Raman spectroscopy (TERS) experiments towards large signal enhancement and high spatial resolution. In this work, we report a controllable fabrication method to prepare TERS-active tips by modifying the tip apex at the atomic scale, and propose two important criteria to in-situ judge the tip's TERS activity for tip-enhanced Raman measurements. One criterion is based on the downshift of the first image potential state to monitor the coupling between the far-field incident laser and near-field plasmon; the other is based on the appearance of the low-wavenumber Raman peaks associated with an atomistic protrusion at the tip apex to judge the coupling efficiency of emissions from the near field to the far field. This work provides an effective method to quickly fabricate and judge TERS-active tips before real TERS experiments on target molecules and other materials, which is believed to be instrumental for the development of TERS and other tip-enhanced spectroscopic techniques.
Internal quantum reference frames for finite Abelian groups
Authors: Höhn Philipp A. , Krumm Marius , Müller Markus P.
Published: November 2022

Employing internal quantum systems as reference frames is a crucial concept in quantum gravity, gauge theories, and quantum foundations whenever external relata are unavailable. In this work, we give a comprehensive and self-contained treatment of such quantum reference frames (QRFs) for the case when the underlying configuration space is a finite Abelian group, significantly extending our previous work [M. Krumm, P. A. Höhn, and M. P. Müller, Quantum 5, 530 (2021)]. The simplicity of this setup admits a fully rigorous quantum information–theoretic analysis, while maintaining sufficient structure for exploring many of the conceptual and structural questions also pertinent to more complicated setups. We exploit this to derive several important structures of constraint quantization with quantum information–theoretic methods and to reveal the relation between different approaches to QRF covariance. In particular, we characterize the “physical Hilbert space”—the arena of the “perspective-neutral” approach—as the maximal subspace that admits frame-independent descriptions of purifications of states. We then demonstrate the kinematical equivalence and, surprising, dynamical inequivalence of the “perspective-neutral” and the “alignability” approach to QRFs. While the former admits unitaries generating transitions between arbitrary subsystem relations, the latter, remarkably, admits no such dynamics when requiring symmetry-preservation. We illustrate these findings by example of interacting discrete particles, including how dynamics can be described “relative to one of the subystems.”
Flower-like disk resonator for gyroscopic application
Authors: Gu Liutao , Zhang Weiping , Lu Haolin , Wu Yuting , Fan Chongyang
Published: November 2022

In this paper, we propose a novel, flower-like disk resonator (FDR). The structure is made up of concentrically meander-shaped rings that are interconnected by straight beams, which have the potential to provide lower resonant frequency, lower frequency split, higher quality factor (Q), and longer decay time (τ). In comparison to the traditional ring-like disk resonator (RDR), the FDR has better immunity to crystal orientation error and fabrication errors owing to its all-linear structure. The prototype of this design is manufactured by silicon on insulator fabrication technique. The frequency response test and quality factor test are implemented at room temperature and under vacuum (5 Pa) using a readout circuit with feed-through cancellation. The results show that the frequency split of the FDR is less than 7.7 Hz without electrostatic tuning. The Q and τ are 21 883 and 0.69 s, respectively. With the same structure parameters, the resonant frequency and frequency split are decreased by 39.1% and 70.2%, and the Q and τ are greatly improved by 63.8% and 172%, respectively, compared to the RDR.

Authors: Shi Zongqian , Fu Guiling , Wang Kun , Cao Ziyang
Published: November 2022

Numerical investigation was carried out on the evolution of inhomogeneous energy deposition of polarity effects in negative polarity electrical explosion of aluminum wire in vacuum. First, radial electric field distribution of the aluminum wire was simulated. The results showed that the initial electric field near electrodes was much smaller than that in the middle of the wire. A model of electrical wire explosion based on ZEUS-EW with artificial limitation on breakdown time of the aluminum wire was used to simulate the behavior of inhomogeneous energy deposition of the polarity effect. The complete evolution process of electrical explosion of the aluminum wire with inhomogeneous energy deposition was further explored and qualitatively divided into three stages according to the simulation results. Finally, the influence of some factors on the inhomogeneous energy deposition simulation was investigated. This study provides some help for a better understanding of the polarity effect in the process of wire explosion.
A density functional theory study of twin T-graphene as an anode material for Na-ion-based batteries
Authors: Majidi Roya , Ayesh Ahmad I.
Published: November 2022

The potential features of twin T-graphene for anodic applications are studied. The adsorption energy, energy barrier, maximum storage capacity, and electronic properties are calculated by density functional theory. It is found that Na adsorption on twin T-graphene is an exothermic process. The twin T-graphene shows a high calculated specific capacity for Na atoms compared to graphite and other two-dimensional carbon allotropes. A relatively slight diffusion energy barrier guarantees fast charging as well as discharging process in Na-ion batteries based on twin T-graphene. A transition between semiconducting and metallic properties, as a vital condition for ion diffusion on the anode material, is observed during the adsorption process. The charge exchange between the Na atom to the sheet leads to ionic interaction between the adsorbed atom and the host sheet, which is necessary for the reversibility of Na adsorption on the twin T-graphene sheet in the batteries. Our calculations suggest that twin T-graphene is an appropriate anode material for use in Na-ion batteries.
Flow transitions in triple-helical microchannel involving novel parallel flow patterns

Published: November 2022

Triple-helical microchannel (THM) constitutes a unique configuration for implementing parallel flows with enhanced interfacial mass transfer through torsion-induced advection in the bulk phases. Key operational aspects include identifying stable regimes of parallel flow with respect to phase flow rates and characterizing the flow intensification achieved through secondary flow. The current work investigates two-phase flow, typical in liquid–liquid extraction operation, inside THM over a wide range of flow rates. Flow visualization and allied image analysis revealed a sequential flow transition with increasing ratio of organic to aqueous flow rates (qO/qA): from one stable “arc” helical parallel flow regime for qO/qA<1 to an intermittent slug flow regime and finally to another “clip” helical parallel flow regime for qO/qA≥1. The transition is theoretically explained based on different interfacial and instability phenomena, and the effects of centrifugal forces. The parallel flow regimes were exclusively assessed by evaluating the flow fields based on phase contours obtained experimentally and quantifying the secondary flow intensification based on Dean number in individual phases. Results establish greater stability of the clip parallel flow regime based on the higher organic phase capillary number and also greater flow intensification in this regime based on Dean number. Overall, the analysis elucidates two-phase parallel flow operation in THM, unfolding novel phenomena and physics.
Design and development of a novel piezoelectric caudal fin-like underwater thruster with a single vibration mode
Authors: Liu Rui , Zhao Heng , Wang Liang , Jin Jiamei , Wu Yifeng
Published: November 2022

The flapping-motion of the caudal fin allows the fish to swim with high efficiency and mobility, particularly in terms of persistence, propulsion, and acceleration. This has led to theoretical and practical research on the development of robotic caudal fin thrusters that offer similar properties and performance. However, the current caudal fin thrusters are driven by electromagnetic motors, which require a transmission system that makes them difficult to miniaturize, and need protection against water intrusion. To address these issues, this paper proposes a novel piezoelectric caudal fin thruster with a fully open structure that has no chambers in any of its parts. The converse, piezoelectric effect and direct friction drive principle are used to make a rotation unit for the piezoelectric actuator drive and achieve a reciprocating motion that makes the caudal fin flap. The proposed piezoelectric caudal fin thruster has an open and simple structure. It has a weight of 30 g, a length of 89 mm, and a thrust of 0.07 N. It is easy to miniaturize and is lighter, smaller, and more efficient than previously reported caudal fin thrusters that were based on ionic polymer–metal composites and shape memory alloys. Experimental results verified the effectiveness of the proposed design, which can be easily scaled up or down in size depending on the operating situation.
Unified calculation of multi-energy flow for integrated energy system based on difference grid
Authors: Liang Ziwen , Mu Longhua
Published: November 2022

The comprehensive utilization of electricity, gas, and heat energy is an important way of energy transformation. However, different energy forms follow different physical laws, which brings great challenges to the collaborative analysis and optimization of the integrated energy system (IES). In this paper, a unified time-domain model of IES is developed based on the two-port network equivalence theory. First, the unified linear equations for IES are derived according to the basic dynamic models of electricity, gas, and heat networks. Second, a unified model of the multi-energy branch based on the finite difference scheme is proposed. The complex internal information of the branch is transformed into equivalent transfer matrixes of initial and boundary conditions. Finally, combined with the network topological equations, a multi-energy flow calculation model is established. Numerical simulation results show that the proposed modeling method has higher computational efficiency than the traditional finite difference method.
Engineering Models for Wind Turbine Computations
Authors: Bangga Galih
Published: November 2022

In any wind turbine design process, the calculations of the blade loads and rotor performance serve as the foundations of the analyses. In practice, these activities are carried out using simplified methods commonly called “engineering models.” We have learned the basic of wind energy aerodynamics in Chap. 2 and now we will learn further about the fundamental aspects of engineering models in this chapter, which covers two major aspects. The first part deals with the formulations of the momentum theory and the steady blade element momentum (BEM) theory. The analyses are further elaborated in the second part, which deals with the unsteady BEM modeling. Several latest improvements of the modeling strategies are presented in this chapter. Finally, the last part of the chapter deals with the vortex line method and its characteristics.

Women in Signs
Authors: Topacio Katrina Ninfa M.
Published: November 2022

Although gaining momentum in research, the issue of gender representations in the Linguistic Landscape demands
more attention. Hence, this study aims to explore the issue of language and gender in the LL of the red-light district (RLD) of
Ermita-Malate, Manila, using frameworks from semiotics, multimodality, and feminist stylistics. Particularly, it seeks to answer
questions on verbal and non-verbal choices in sign production, and the role of women in the process of interpretation, production,
and function of these signs in the RLD. The linguistic and multimodal analysis reveals that the RLD Ermita-Malate, Manila,
features linguistic diversity, and that language and image choice support the highly consumerist activities observed in the area.
A more in-depth feminist reading of the texts also reveals that women’s role in sign production is limited to the commodification
of their images whose function is highly symbolical and imaginative.
EpCAM proteolysis and release of complexed claudin-7 repair and maintain the tight junction barrier
Authors: Higashi Tomohito , Saito Akira C. , Fukazawa Yugo , Furuse Mikio , Higashi Atsuko Y. , Ono Masahiro , Chiba Hideki
Published: November 2022

TJs maintain the epithelial barrier by regulating paracellular permeability. Since TJs are under dynamically fluctuating intercellular tension, cells must continuously survey and repair any damage. However, the underlying mechanisms allowing cells to sense TJ damage and repair the barrier are not yet fully understood. Here, we showed that proteinases play an important role in the maintenance of the epithelial barrier. At TJ break sites, EpCAM–claudin-7 complexes on the basolateral membrane become accessible to apical membrane-anchored serine proteinases (MASPs) and the MASPs cleave EpCAM. Biochemical data and imaging analysis suggest that claudin-7 released from EpCAM contributes to the rapid repair of damaged TJs. Knockout (KO) of MASPs drastically reduced barrier function and live-imaging of TJ permeability showed that MASPs-KO cells exhibited increased size, duration, and frequency of leaks. Together, our results reveal a novel mechanism of TJ maintenance through the localized proteolysis of EpCAM at TJ leaks, and provide a better understanding of the dynamic regulation of epithelial permeability.

Positive longitudinal magnetoconductivity induced by chiral magnetic effect in mercury selenide
Authors: Lonchakov Alexander T , Bobin Semyon B
Published: November 2022

A negative longitudinal magnetoresistance without any sign of saturation was found in a non-centrosymmetric Weyl semimetal (WSM) candidate mercury selenide in an electron concentration range of 5.5 × 1015–1.7 × 1017 cm−3 and a temperature range of 0.33–150 K. The magnitude of the effect varies with a sample from

≈

10% up to

≈

30% in a magnetic field of 12 T at T = 150 K. Moreover, the positive contribution to magnetoconductivity has a characteristic quadratic dependence on the magnetic field, increasing with a charged center concentration at T = 150 K. The most likely explanation for the discovered longitudinal magnetoconductivity feature lies in the chiral magnetic effect, which is inherent to WSMs. The role of the Dyakonov–Perel mechanism in inter-nodal spin relaxation is discussed in regard to HgSe.

Plasmonic structures can help enhance optical activity in the ultraviolet (UV) region and therefore enhancing photocatalytic reactions and the detection of organic and biological species. Most plasmonic structures are composed of Ag or Au. However, producing structures small enough for optical activity in the UV region has proved difficult. In this study, we demonstrate that aluminium nanowires are an excellent alternative. We investigated the plasmonic properties of the Al nanowires as well as the optoelectronic properties of the surrounding a − Si matrix by combining scanning transmission electron microscopy imaging, electron energy loss spectroscopy and electrodynamic modelling. We have found that the Al nanowires have distinct plasmonic modes in the UV and far UV region, from 0.75 eV to 13 eV. In addition, simulated results found that the size and spacing of the Al nanowires, as well as the embedding material were shown to have a large impact on the type of surface plasmon energies that can be generated in the material. Using electromagnetic modelling, we have identified the modes and illustrated how they could be tuned further.
Current status of diagnostic reference levels in interventional cardiology
Authors: Sanchez Roberto M , Siiskonen Teemu , Vano Eliseo
Published: November 2022

Interventional cardiology provides indisputable benefits for patients but uses a substantial amount of ionising radiation. The diagnostic reference level (DRL) is the tool recommended by the International Commission on Radiological Protection to optimise imaging procedures. In this work, a review of studies dealing with radiation dose or recommending DRL values for interventional cardiology since 2010 is presented, providing quantitative and qualitative results. There are many published papers on coronary angiography (CA) and percutaneous coronary intervention. The DRL values compiled for different continental regions are different: the DRL for CA is about 35 Gy cm2 for Europe and 83 Gy cm2 for North America. These differences emphasise the need to establish national DRLs considering different social and/or economic factors and the harmonisation of the survey methodology. Surveys with a large amount of data collected with the help of dose management systems provide more reliable information with less chance of statistical bias than those with a small amount of data. The complexity of procedures and improvements in technology are important factors that affect the radiation dose delivered to patients. There is a need for additional data on structural and electrophysiological procedures. The analysis of paediatric procedures is especially difficult because some studies present results split into age bands and others into weight bands. Diagnostic procedures are better described, but there is a great variety of therapeutic procedures with different DRL values (up to a factor of nine) and these require a dedicated review.
A novel method for determining water saturation of porous media in relative permeability measurement using DPT
Authors: Shen Shaicheng , Fang Zhiming , Li Xiaochun
Published: November 2022

Relative permeability is essential for understanding porous media’s gas and water seepage characteristics and establishing production schedules in practical engineering applications. However, the movable water is too small to be detected in ultra-lowpermeability rocks, and it is difficult to determine the water saturation in the relative permeability measurement accurately. In this study, a differential pressure transducer (DPT) was applied to self-developed apparatus to quantify displaced water precisely. The results indicate that: (a) both the permeability and the relative permeability measurement results show high stability in repeatability tests with the application of DPT. (b) The final cumulative water flow data measured by the DPT is reliable; the relative error of the electronic balance and DPT value was less than 4%. (c) This self-developed instrument can obtain the relative permeability curve for ultra-low permeability rocks, such as tight sandstone and anthracite coal. Although there are limitations, this technique provides an economical and reliable pathway for studying the seepage characteristics of gas and water in ultra-low permeability rocks.
A passive and wireless smart washer for monitoring bolt pretightening force
Authors: Keke Guo , Yongfeng Zhao , Wenlian Wang
Published: November 2022

For the improvement of the safe operation of specific structures, it is crucial to monitor the bolt pretightening force. Conventional approaches frequently call for complicated systems that are challenging to install and cumbersome to operate in order to produce precise measurements. It is suggested that a passive wireless smart washer be used to track bolt pretightening force. The smart washer is installed together with the bolts, and a handheld terminal can be used at any moment to detect the tightening force of many bolts. Pretightening force and strain sensing are obtained by the washer structure, and the circuit in the washer obtains energy via a printed antenna to start the acquisition of a signal based on Near Field Communication technology. The data is then sent to the terminal for visualization and analysis. The prototype’s experimental findings demonstrate that the smart washer can keep track of the bolt’s pretightening force both during and after tightening.

We employed the effective-field theory with correlations to study the hysteresis and thermodynamic properties of a bilayer graphene-like ring with edge decorated by a ferrimagnetic mixed-spin (2, 5/2) Ising model. The temperature dependence of magnetization, susceptibility, internal energy and specific heat of the system are illustrated in detail. As well, we depict the hysteresis behaviors and phase diagram with various parameters. The results showed the significance of the anisotropy, the magnetic field as well as the exchange coupling in controlling hysteresis behaviors and various magnetic quantities. The possibility of rich multiple-loop hysteresis and reentrant behaviors are found, sensitive to the competition among the physical parameters.
Electrical characteristics of (AgNPs-PVA)-based Schottky diode and its application as a low-voltage varistor devices
Authors: Khalil R
Published: November 2022

In this report, we studied the influence of silver nanoparticles (AgNPs) on the electrical conductivity of Polyvinyl Alcohol (PVA) as a semiconductor nanocomposites active layer. Here, the Schottky junction is constructed by mechanically pressing a copper (Cu) electrode onto a AgNPs-PVA nanocomposite, which shows rectification behavior at room temperature. The synthesis of silver nanoparticles (AgNPs) was achieved by the physical reduction of silver nitrate using an ultraviolet lamp. The nanocomposite films were created using a casting technique. An ultraviolet spectrophotometer (UV–vis), which displayed maximum absorbance at 430 nm, was used to confirm the synthesis of AgNPs and carry out the optical band gap. The charge carrier transport properties of AgNPs-PVA film were investigated by using impedance spectroscopy and I–V measurements. Then, AC impedance analysis was used to determine grain and grain boundary resistances; current-voltage analysis enabled the barrier height (Φ) to be determined. Moreover, the metal/semiconductor (Cu/AgNPs-PVA) Schottky barrier was confirmed as an equivalent circuit model via the Nyquist plot. Based on thermoionic emission theory, the characteristic I–V induced rectifying Schottky behavior can be understood. Moreover, the AgNPs-PVA nanocomposite exhibited hysteresis behavior under multiple repetitive measurements. For low voltage varistor devices, the nonlinear behavior may be completely utilized.

In this work, a two dimensional (2D) axisymmetric fluid model for an atmospheric pressure plasma jet (APP jet) driven by a 8 kV voltage pulse with a repetition frequency of 50 kHz has been investigated. The aim is to identify the physical phenomena taking place in a cold plasma jet at atmospheric pressure assuming an argon pathway in the air. This model is a platform for future works where the simulated reactor will be used for different plasma jet applications. It is built through the coupling between plasma discharge and flow physics using COMSOL@ Multi-physics software. The simulation results showed that the high value of the electric field in the head of the plasma jet channel attracts free electrons and ensures its propagation to around 1cm of length with an electron density of 1020 m−3. We have also shown that electrons in the neutral zone of the plasma (channel) have a lower temperature compared to electrons in electrostatic sheaths (channel boundaries), although, their temperature remains remarkably higher than neutrals and ions ones. The total electric current calculated by the proposed model takes a maximum value of 7.71 mA. This value increases with increasing tube reactor diameter which changes the reactor equivalent capacity.
How general is the strong cosmic censorship bound for quasinormal modes?
Authors: Konoplya R.A. , Zhidenko A.
Published: November 2022

Hod's proposal claims that the least damped quasinormal mode of a black hole must have the imaginary part smaller than half of the surface gravity at the event horizon.
The Strong Cosmic Censorship in General Relativity implies that this bound must be even weaker: half of the surface gravity at the Cauchy horizon. The appealing question is whether these bounds are limited by the Einstein theory only?
Here we will present numerical evidence that once the black hole size is much smaller than then the radius of the cosmological horizon, both the Hod's proposal and the strong cosmic censorship bound for quasinormal modes are satisfied for general spherically symmetric black holes in an arbitrary metric theory of gravity. The low-lying quasinormal frequencies have the universal behavior in this regime and do not depend on the near-horizon geometry, but only on the asymptotic parameters: the value of the cosmological constant and black hole mass.
Constraining scale dependent growth with redshift surveys
Authors: Denissenya Mikhail , Linder Eric V.
Published: November 2022

Ongoing and future redshift surveys have the capability to
measure the growth rate of large scale structure at the
percent level over a broad range of redshifts, tightly
constraining cosmological parameters. Beyond general
relativity, however, the growth rate in the linear density
perturbation regime can be not only redshift dependent but
scale dependent, revealing important clues to modified gravity.
We demonstrate that a fully model independent approach of binning
the gravitational strength G
eff (k,z) matches
scalar-tensor results for the growth rate fσ
8(k,z) to
0.02%–0.27% rms accuracy. For data of the quality of
the Dark Energy Spectroscopic Instrument (DESI) we find the
bin values can be constrained to 1.4%–28%. We also
explore the
general scalar-tensor form, constraining the amplitude and
past and future scalaron mass/shape parameters.
Perhaps most interesting is the strong complementarity
of low redshift peculiar velocity data with DESI-like
redshift space distortion measurements, enabling
improvements up to a factor 6–7 on 2D joint confidence
contour areas.
Finally, we quantify some issues with gravity
parametrizations that do not include all the key physics.
The velocity-dependent J-factor of the Milky Way halo: does what happens in the galactic bulge stay in the galactic bulge?
Authors: Kiriu Kenny , Kumar Jason , Runburg Jack
Published: November 2022

We consider the angular distribution of the photon signal which could arise
from velocity-dependent dark matter annihilation within the Galactic bulge. We find that, for the
case of Sommerfeld-enhanced annihilation, dark matter annihilation within the bulge is
dominated by slow speed particles which never leave the bulge, allowing one to find a simple
analytic relationship between the dark matter profile within the Galactic bulge and the angular
distribution. On the other hand, for the case p- or d-wave annihilation, we find that
the small fraction of high-speed particles which can leave the bulge provide a significant,
often dominant, contribution to dark matter annihilation within the bulge. For these scenarios,
fully understanding dark matter annihilation deep within the Galactic bulge, and the angular distribution of
the resulting photon signal, requires an understanding of
the dark matter profile well outside the bulge. We consider the Galactic Center excess in
light of these results, and find that an explanation of this excess in terms of p-wave
annihilation would require the dark matter profile within the bulge to have a much steeper
profile than usually considered, but with uncertainties related to the behavior of the profile
outside the bulge.

CASA, the Common Astronomy Software Applications, is the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA), and is frequently used also for other radio telescopes. The CASA software can handle data from single-dish, aperture-synthesis, and Very Long Baseline Interferometery (VLBI) telescopes. One of its core functionalities is to support the calibration and imaging pipelines for ALMA, VLA, VLA Sky Survey, and the Nobeyama 45 m telescope. This paper presents a high-level overview of the basic structure of the CASA software, as well as procedures for calibrating and imaging astronomical radio data in CASA. CASA is being developed by an international consortium of scientists and software engineers based at the National Radio Astronomy Observatory (NRAO), the European Southern Observatory, the National Astronomical Observatory of Japan, and the Joint Institute for VLBI European Research Infrastructure Consortium (JIV-ERIC), under the guidance of NRAO.

Published: November 2022

The real-time measurement of optical activity is of great significance for studying the chemical reactions of chiral molecules. In this study, we have built a set of linear common path optical weak measurement chiral sensor system in frequency domain, and the optical sensitivity of the system feasibly reaches 1524 for activity. Using this system, we have realized the state measurement of the ultrafast alkaline hydrolysis reaction of gluconolactone under different concentrations of catalyst. This study shows that the optical weak measurement chiral sensor can well monitor and compare the degree of hydrolysis reaction, and partly reflect the approximate change of the optical rotation in the real-time process of hydrolysis. Optical weak measurement chiral sensing does not require separation and labeling molecules, and has great application potential for the production and development of chiral compounds, especially chiral drugs.

We present a mechanism for improving the sensitivity of microwave (MW) electric field (E-field) measurement using dual-MW-dressed electromagnetically induced transparency in a 5S

85Rb atomic coherent system. An auxiliary MW (A-MW) field is introduced into the MW E-field measurement system, which consists of a probe, coupling lasers, and a target MW (T-MW) field. When the A-MW field frequency is tuned to be the same as the T-MW field and its power is adjusted to a suitable range, the T-MW field strength can be read out effectively. Finally, the sensitivity of MW E-field measurement is improved by about two orders of magnitude compared to that without an A-MW field. In addition, this mechanism is proven to be applicable for all frequency bands covered by Rydberg energy levels. This work opens up a novel pathway for the realization of high-sensitivity MW E-field measurement with Rydberg atoms.
