Authors: Imai Hisanori , Tetsumoto Akira , Yamada Hiroko , Nakamura Makoto 
Published: December 2020

AbstractThe present study aimed to identify the factors regulating aspiration rate (AR) of backflush needles and to compare those factors across various backflush needles from different manufacturers. The 27-gauge (27G), 25-gauge, and 23-gauge backflush needles from four different manufacturers, Alcon, MedOne, VitreQ, and DORC, were used for this experiment. AR was measured at four different aspiration vacuum levels: 100, 200, 400, and 650 mmHg. AR was significantly increased as the aspiration vacuum level increased when both aspirating balanced salt solution (BSS) and ethylene glycol; however, 27G products from VitreQ and MedOne were unable to aspirate ethylene glycol at the low aspiration vacuum level of 100 mmHg. When aspirating BSS at the high aspiration vacuum level of 650 mmHg, a smaller gauge number generally resulted in a significantly higher AR. AR, inner diameter, and cross-sectional area in Alcon products were significantly larger in any gauge, and the shaft length of Alcon products was significantly shorter than those of other manufacturers’ products in any gauge. Cross-sectional area negatively correlated with the degree of shaft deflection (r2 = 0.21, p = 0.042). These results imply that AR differs significantly among backflush needles and among companies depending on the shaft cross-sectional area.

Purpose
For cochlear implant users, the ability to use the telephone is often seen as an important landmark during rehabilitation and an indicator of cochlear implant benefit. The goal of this study was to develop a short questionnaire exploring the ability to use the telephone in cochlear implant users, named Telislife, and test it in a group of experienced users.

Method
This prospective multicenter study was based on the completion of self-administrated questionnaires. The Telislife includes 20 items using a 5-point Likert scale for answers. Speech recognition scores were obtained with monosyllabic word lists at 70 dB HL. Quality of life was evaluated with the Nijmegen Cochlear Implant Questionnaire. This study included 55 adult patients wearing a cochlear implant for over 1 year.

Results

The Telislife questionnaire showed excellent reliability (Cronbach's α = .91). A significant correlation was found between Telislife scores and Nijmegen Cochlear Implant Questionnaire scores (
r
= .69,
p
< .001) and speech recognition scores (
r
= .35,
p
= .007).

Conclusion
Given significant correlations between Telislife scores and both speech recognition and quality of life and given its short form, the Telislife questionnaire appears to be a reliable tool to evaluate cochlear implant outcomes in clinical practice.

Linear functional state bounding for positive singular systems with unbounded delay and disturbances varying within a bounded set
Authors: Sau Nguyen Huu 
Published: December 2020

AbstractIn this paper, the linear functional state bounding problem, which is considered in [25], is extended to the singular system with unbounded delay. Firstly, some conditions are presented to guaranteed positivity, regularity, impulse‐free, and the component‐wise bound for the state vector of the singular system without disturbance. Then, based on the results obtained and by using state transformations, the smallest component‐wise ultimate bound of the state vector of the singular system with bounded disturbances is derived. By using the new technique, some sufficient conditions were proposed given in terms of the linear programming/Hurwit matrix/spectral abscissa for linear functional state bounding problems of the singular system with unbounded delay. Finally, a numerical example is given to illustrate the obtained results.
Candidate bus selection for dynamic VAR planning towards voltage stability enhancement considering copula‐based correlation of wind and load uncertainties
Authors: Chi Yuan , Xu Yan , Zhang Rui 
Published: December 2020

AbstractAs a critical step of VAR planning, candidate bus selection can significantly reduce the scale of the planning problem without impairing the optimality of the planning decisions. A novel candidate bus selection method is proposed considering not only the capacity sensitivity of candidate buses, but also the correlation among uncertainties of wind power generation and load demands. First, two metrics are proposed for different sensitivity analysis purposes to evaluate voltage performance in the post‐contingency stage comprehensively, considering the extent of the voltage deviation and voltage recovery time simultaneously. Then, D‐vine copulas are constructed systematically and employed to generated correlated operational scenarios for the dependent variable sensitivity analysis based on Kucherenko indices. Morris screening method is used for the independent capacity sensitivity analysis of the candidate buses. Finally, a 2‐dimensional candidate bus selection process is proposed for the decision‐makers to determine the candidate buses flexibly. The proposed method is tested on a modified Nordic 74‐bus system with an industry‐standard complex load model. Simulation results verify the effectiveness and accuracy of the proposed method.
Mechanical defect identification for gas‐insulated switchgear equipment based on time‐frequency vibration signal analysis

Published: December 2020

AbstractMechanical defect is an important reason for the failure of gas‐insulated switchgear (GIS) equipment. Based on the time‐frequency characteristic vibration signal analysis on five kinds of mechanical defects, a novel intelligent algorithm model combining complementary ensemble empirical mode decomposition (CEEMD) and genetic algorithm improved kernel fuzzy mean clustering (GAKFCM) was proposed to identify the mechanical defect type. First, the mechanical defect platform and detection system were built. Then CEEMD and IMF sensitivity factors were used to analyse the time‐frequency signal of five kinds of vibration defects, and the feature extraction was performed on the processed vibration signals. Finally, the mechanical vibration defect recognition model was established based on the GAKFCM algorithm and its validity was verified. Results show that the developed detection system can detect mechanical vibration signals sensitively. Singular values, frequency band lines and entropy can reflect the energy attenuation and distribution differences for different type of mechanical defect vibration signals. The proposed GAKFCM clustering model combining the above vibration feature parameters can effectively find and diagnose the mechanical defect of GIS equipment. Its recognition accuracy reaches 96.74%, especially for the loose contact seat bolts and poor contact failures of the disconnector.
A new recognition algorithm for high‐voltage lines based on improved LSD and convolutional neural networks

Published: December 2020

AbstractWith the development of high‐voltage transmission and artificial intelligence technology, unmanned line inspection has become the inevitable trend of current electric power inspection. A new recognition algorithm for high‐voltage lines is proposed based on colour (Red, Green, Blue) RGB image to support the unmanned line inspection. Firstly, in order to solve the problem of missing weak edges in image edge detection, an improved Canny algorithm is proposed. Fourier transform Gaussian filter is introduced to enhance the high‐frequency signal of the image, which makes the extracted edge information more complete. At the same time, an improved line segment detector (LSD) algorithm is developed to extract the high‐voltage line. The complementary edge information of the three channels of the colour RGB image is analyzed, and the calculation formula of the horizontal line angle is improved, which greatly reduces the possibility of false detection and missed detection in the high‐voltage line extraction. In addition, the convolution neural network (CNN) is used to accurately recognize the extracted high‐voltage lines, which reduces the interference of non–high‐voltage lines. Simulation results show that the proposed algorithm has high recognition accuracy and strong robustness in the complex environment.
Identifying the degree of genetic interactions using Restricted Boltzmann Machine—A study on colorectal cancer

Published: December 2020

AbstractThe phenomenon of two or more genes affecting the expression of each other in various ways in the development of a single character of an organism is known as gene interaction. Gene interaction not only applies to normal human traits but to the diseased samples as well. Thus, an analysis of gene interaction could help us to differentiate between the normal and the diseased samples or between the two/more phases any diseased samples. At the first stage of this work we have used restricted Boltzmann machine model to find such significant interactions present in normal and/or cancer samples of every gene pairs of 20 genes of colorectal cancer data set (GDS4382) along with the weight/degree of those interactions. Later on, we are looking for those interactions present in adenoma and/or carcinoma samples of the same 20 genes of colorectal cancer data set (GDS1777). The weight/degree of those interactions represents how strong/weak an interaction is. At the end we will create a gene regulatory network with the help of those interactions, where the regulatory genes are identified by using Naïve Bayes Classifier. Experimental results are validated biologically by comparing the interactions with NCBI databases.

Context. The ESA Rosetta mission has allowed for an extensive in situ study of the comet 67P/Churyumov-Gerasimenko. In measurements performed by the ram gauge of the COmet Pressure Sensor (COPS), observed features are seen to deviate from the nominal ram gauge signal. This effect is attributable to the sublimation of the volatile fraction of cometary icy particles containing volatiles and refractories.
Aims. The objective of this work is to investigate the volatile content of icy particles that enter the COPS ram gauge.
Methods. We inspected the ram gauge measurements to search for features associated with the sublimation of the volatile component of cometary particles impacting the instrument. All the sublimation features with a high-enough signal-to-noise ratio were modelled by fitting one or more exponential decay functions. The parameters of these fits were used to categorise different compositions of the sublimating component.
Results. Based on features that are attributable to ice sublimation, we infer the detection of 73 icy particles containing volatiles. Of these, 25 detections have enough volatile content for an in-depth study. From the values of the exponential decay constants, we classified the 25 inferred icy particles into three types, interpreted as different volatile compositions, which are possibly further complicated by their differing morphologies. The available data do not give any indication as to which molecules compose the different types. Nevertheless, we can estimate the total volume of volatiles, which is expressed as the diameter of an equivalent sphere of water (density of 1 g cm−3). This result was found to be on the order of hundreds of nanometres.

Aims. We report on ESPRESSO high-resolution transmission spectroscopic observations of two primary transits of the highly irradiated, ultra-hot Jupiter-sized planet, WASP-76b. We investigated the presence of several key atomic and molecular features of interest that may reveal the atmospheric properties of the planet.
Methods. We extracted two transmission spectra of WASP-76b with R ≈ 140 000 using a procedure that allowed us to process the full ESPRESSO wavelength range (3800–7880 Å) simultaneously. We observed that at a high signal-to-noise ratio, the continuum of ESPRESSO spectra shows ‘wiggles’, which are likely caused by an interference pattern outside the spectrograph. To search for the planetary features, we visually analysed the extracted transmission spectra and cross-correlated the observations against theoretical spectra of different atomic and molecular species.
Results. The following atomic features are detected: Li I, Na I, Mg I, Ca II, Mn I, K I, and Fe I. All are detected with a confidence level between 9.2 σ (Na I) and 2.8 σ (Mg I). We did not detect the following species: Ti I, Cr I, Ni I, TiO, VO, and ZrO. We impose the following 1 σ upper limits on their detectability: 60, 77, 122, 6, 8, and 8 ppm, respectively.
Conclusions. We report the detection of Li I on WASP-76b for the first time. In addition, we confirm the presence of Na I and Fe I as previously reported in the literature. We show that the procedure employed in this work can detect features down to the level of ~0.1% in the transmission spectrum and ~10 ppm by means of a cross-correlation method. We discuss the presence of neutral and singly ionised features in the atmosphere of WASP-76b.

Authors: Liu Shi , Cheng Yongjun , Zhang Song Bin 
Published: December 2020

Aims. The primary motivation of this paper is to provide accurate atomic properties of F-like ions with Z = 20−30, including energy levels, line strengths, static dipole polarizabilities, and lifetimes. In addition, a detailed analysis is also carried out to explore the convergence and uncertainties of our results.
Methods. Large-scale B-spline relativistic configuration interaction calculations are carried out to generate the atomic properties of F-like ions. The radial parts of one-electron Dirac orbitals are obtained from the relativistic self-consistent field procedure in which the Breit Interaction and QED corrections (vacuum polarization and self-energy terms) are also included. A numerical method, called Emu CI, is adopted to decrease the size of CI matrix significantly without loss of much accuracy.
Results. Energy levels and line strengths for electric-dipole (E1), electric-quadrupole (E2), and magnetic-dipole (M1) transitions are provided for the 250 lowest levels of each system, showing a good agreement with available theoretical and experimental information. The static dipole polarizabilities and lifetimes for the ten lowest states are also reported. A statement for the convergence and uncertainties of our results is presented.

Published: December 2020

Significance
Microcrystal electron diffraction (MicroED) is an electron cryo-microscopy (cryoEM) method for determining structures using submicron crystals. Until now, determining structures of membrane proteins by MicroED required that the protein crystals be in a solution amenable to standard cryoEM blotting and vitrification protocols. Here, we show that membrane protein microcrystals grown in a viscous bicelle mixture can become amenable to MicroED analyses by using modified blotting procedures combined with focused ion-beam milling. Our findings provide a basis for solving membrane protein structures using crystals embedded in a viscous media by MicroED.
Interpretation of focus in Haitian Creole
se-clefts
Authors: Walker-Cecil Kezia , Destruel Johnson Emilie 
Published: December 2020

Abstract
While past literature on Haitian Creole focus
structures primarily concentrates on predicate clefts (see DeGraff, 1995; Glaude & Zribi-Hertz,
2012; Harbour,
2008; Lefebvre,
1990), few authors use empirical data to justify proposed
interpretations of clefts. In this paper, we empirically test which
interpretations are available in se-clefts,
expanding on previous work on clefts in Haitian Creole and other
languages. Our first experiment investigates the influence of
predicate gradability (Harbour,
2008) and syntactic structure (Glaude & Zribi-Hertz, 2012) on
predicate cleft interpretation, using a felicity judgment task.
Prior work on Haitian se-clefts has not discussed
the exhaustive inference, an inference conveyed in similar clefts
cross-linguistically (see Destruel et al., 2015; Horn, 1981). Our second experiment examines
the exhaustivity inference in both predicate and nominal
se-clefts, comparing Haitian speakers’
judgments to results from similar clefts in other languages,
particularly French, via a forced-choice task adapted from Onea and Beaver (2011).
Me gohtaba ehta linguaji barranquenha
Authors: Garrett Jordan 
Published: December 2020

Abstract
The villa of Barrancos, Portugal, has a
multilingual population that in addition to European Portuguese and
Spanish also speaks an autochthonous contact variety, Barranquenho.
Previous research on several phonological and morphosyntactic
properties suggest Barranquenho is a mixed language albeit not a
prototypical one. The current study analyzes 895 tokens of object
clitics taken from a corpus of 20 native-speaker interviews and
examines their placement, morphology and distribution in specific
constructions. Results suggest that Barranquenho speakers possess a
mixed clitic system containing both Spanish and Portuguese-like
properties. The data also suggest a more Spanish-like placement
pattern; one that is sensitive to finiteness rather than the
presence/absence of various operators or morphophonological (PF)
restrictions when interpreted in light of current approaches to the
syntax of clitics. Moreover, this study has implications for
existing typological models of contact varieties and point to future
research regarding the application of syntactic models to these
approaches.
Donepezil and Cognitive Remediation Therapy to Augment Treatment of Alcohol use Disorder Related Mild Cognitive Impairment (AUD-MCI): An Open Label Pilot Study with Historical Controls
Authors: Bell Morris D. , Pittman Brian , Petrakis Ismene , Yoon Gihyun 
Published: December 2020

Background Pharmacological and psychosocial interventions have only modest efficacy for Alcohol Use Disorder (AUD), and continued alcohol use has brain effects on neurocognition, which place heavy drinkers at increased risk of early onset dementia. The most common neurocognitive deficits are in the domains of executive function and memory, and these deficits may impact AUD treatment outcomes. AUD related Mild Cognitive Impairment (AUD-MCI) is a diagnosis in DSM-V and ICD-10. Donepezil, a cholinesterase inhibitor, is currently FDA approved for treatment of dementia, and recent preclinical research suggests anticholinesterase agents may treat alcoholism. Another approach to cognitive recovery is Cognitive Remediation Therapy (CRT). Recent research supports CRT efficacy in schizophrenia and related disorders, and some research suggests that CRT could improve neurocognition in substance abuse disorders (SUDs). This is the first report of an open-label clinical trial that combined donepezil with CRT to improve neurocognitive and clinical outcomes in the early phase of AUD recovery. Methods Eleven older male US Veterans with AUD-MCI as determined by Level II neurocognitive criteria and who had recently relapsed participated in an open-label trial of 13 weeks of donepezil combined with CRT. They were compared with matched historical control samples on neurocognitive and clinical outcomes. Results Participants had excellent adherence to donepezil and CRT. Neurocognitive improvements were highly significant on a composite score of learning and memory and executive function measures ( p < .0001) and was significantly better than historical matched controls ( p < .001). On a Clinical Global Impression scale, 90.9% of participants had a good clinical recovery compared with 59.5% of historical matched controls ( p <.052). Conclusions AUD-MCI has not received much research attention but is of considerable public health importance. Findings in this open-label trial of donepezil + CRT should encourage further investigation into the clinical benefit of this combined treatment for AUD-MCI.
