Community context and pCO2 impact the transcriptome of the “helper” bacterium Alteromonas in co-culture with picocyanobacteria
Authors: Barreto Filho Marcelo Malisano , Lu Zhiying , Walker Melissa , Morris J Jeffrey 
Published: November 2022

Abstract
Many microbial photoautotrophs depend on heterotrophic bacteria for accomplishing essential functions. Environmental changes, however, could alter or eliminate such interactions. We investigated the effects of changing pCO2 on gene transcription in co-cultures of 3 strains of picocyanobacteria (Synechococcus strains CC9311 and WH8102 and Prochlorococcus strain MIT9312) paired with the ‘helper’ bacterium Alteromonas macleodii EZ55. Co-culture with cyanobacteria resulted in a much higher number of up- and down-regulated genes in EZ55 than pCO2 by itself. Pathway analysis revealed significantly different transcription of genes involved in carbohydrate metabolism, stress response, and chemotaxis, with different patterns of up- or down-regulation in co-culture with different cyanobacterial strains. Gene transcription patterns of organic and inorganic nutrient transporter and catabolism genes in EZ55 suggested resources available in the culture media were altered under elevated (800 ppm) pCO2 conditions. Altogether, changing transcription patterns were consistent with the possibility that the composition of cyanobacterial excretions changed under the two pCO2 regimes, causing extensive ecophysiological changes in both members of the co-cultures. Additionally, significant downregulation of oxidative stress genes in MIT9312/EZ55 cocultures at 800 ppm pCO2 were consistent with a link between the predicted reduced availability of photorespiratory byproducts (i.e., glycolate/2PG) under this condition and observed reductions in internal oxidative stress loads for EZ55, providing a possible explanation for the previously observed lack of “help” provided by EZ55 to MIT9312 under elevated pCO2. If similar broad alterations in microbial ecophysiology occur in the ocean as atmospheric pCO2 increases, they could lead to substantially altered ecosystem functioning and community composition.
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.
Metabolisches Syndrom und gastrointestinale Krebsvorsorge
Authors: Scherübl Hans 
Published: November 2022

ZusammenfassungKrebs 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.

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

Abstract
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.

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

Abstract
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.

Abstract
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

Abstract
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

Abstract
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

Abstract
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.
Study on the magnetic and hysteresis behaviors in a bilayer graphene-like ring with edge decorated
Authors: Shi Kai-Le , Quan Xing-Wei , Jiang Wei 
Published: November 2022

Abstract
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

Abstract
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.
