Electrochemomechanical deformation (ECMD) of PPyDBS in free standing film formation and trilayer designs

An investigation is reported into the electrochemomechanical deformation (ECMD) of polypyrrole (PPy) doped with dodecylbenzenesulfonate (DBS) in the form of freestanding films and deposited onto conductive substrates (chemically fixed poly-3,4-(ethylenedioxythiophene, PEDOT) based on PVdF (poly(vinylidenefluoride)). Linear actuation has been achieved starting from a trilayer bending actuator design with a stretchable middle layer. To allow evaluation of the proposed design, commercially available PVdF membranes were chosen as model material. For bending trilayer functionality, electronic separation of both electrode layers is essential, but in order to obtain linear actuation, the CP layers on either side are connected to form a single working electrode. The PPyDBS free standing films and PPyDBS deposited on PEDOT-PVdF-PEDOT were investigated by electrochemical methods (cyclic voltammetry, square wave potentials) in a 4-methyl-1,3-dioxolan-2-one (propylene carbonate, PC) solution of tetrabutylammonium trifluoromethanesulfonate (TBACF3SO3). This study also presents a novel method of utilizing scanning ion-conductance microscopy (SICM) to accurately examine the electrochemical redox behavior of the surface layer of the linear actuator using a micropipette tip.
Leadership Empowerment Values: A Literature Review

The purpose of this article is to conduct a literature review related to leadership empowerment viewed from 6 values, namely integrity, collaboration, agility, dedication, innovation and meaningfulness. This study is a literature review of related journals. The literature was collected from 50 journal articles from 2000 to 2021. Based on the results of the review, it is known that the value of integrity in leadership empowerment refers to honesty and consistency between values and behaviors adopted. Collaborative leadership empowerment is needed to foster an environment that supports collaboration at work. Agility in leadership is demonstrated through flexible leadership and can lift the capabilities of the staff, so that they can contribute to the development of the company in a more advanced direction. Dedicated leaders work selflessly, have confidence in what they are doing, the goals they want to achieve, and how to get there. Innovative leaders are leaders who are willing to learn and change, willing to invest in learning and changing existing mindsets of individuals, teams and organizations. Meaningful leadership is characterized by leadership that has quality intellectual, social and moral abilities and has a positive effect on employee work. In short, these six values contribute effectively towards the quality of good leaders.
Stability Analysis of Active Front End and Permanent Magnet Synchronous Generator With Back EMF-Based Sensorless Control for DC Marine Vessels

This article studies the influence of sensorless control on the permanent magnet synchronous generator (PMSG) and pulsewidth modulation (PWM) converter (active front end rectifier, AFE) system for dc marine vessels. Back EMF-based sensorless control is adopted in this article because the minimum speed of PMSG in a dc marine vessel is enough for obtaining a sufficient back EMF signal. First, the output impedance of “PMSG+AFE” system with a typical topology and controller is deduced by small-signal analysis. The stability analysis with constant power load (CPL) is analyzed, including the influence of sensorless control bandwidth on PMSG with a significant per-unit impedance value. Since the inductance parameter affects both the current control and sensorless control, the influence of error in the estimated inductance parameter on the stability of “PMSG+AFE” system is analyzed. To verify the proposed impedance model, output impedance is measured in the simulation and experiment. The stability analysis with the proposed impedance model and load impedance of CPL is provided in MATLAB, and simulation results and experimental measurements are given to verify the analysis.
LiDA: Language-Independent Data Augmentation for Text Classification

Developing a high-performance text classification model in a low-resource language is challenging due to the lack of labeled data. Meanwhile, collecting large amounts of labeled data is cost-inefficient. One approach to increase the amount of labeled data is to create synthetic data using data augmentation techniques. However, most of the available data augmentation techniques work on English data and are highly language-dependent as they perform at the word and sentence level, such as replacing some words or paraphrasing a sentence. We present Language-independent Data Augmentation (LiDA), a technique that utilizes a multilingual language model to create synthetic data from the available training dataset. Unlike other methods, our approach worked on the sentence embedding level independent of any particular language. We evaluated LiDA in three languages on various fractions of the dataset, and the result showed improved performance in both the LSTM and BERT models. Furthermore, we conducted an ablation study to determine the impact of the components in our method on overall performance. The source code of LiDA is available at https://github.com/yest/LiDA.
Origin and development of transient coronal holes

Solar transient coronal holes (TCHs) are short-lived (≤2 days) regions of dimmed X-ray intensity sometimes observed in association with coronal mass ejections. These features, first discovered from Skylab observations, can occur in magnetic unipolar regions on either side of the X-ray posteruptive arcades. They have been suggested as the magnetically open footpoints of associated transient flux ropes observed at 1 AU. We have used images from the Yohkoh Soft X-ray Telescope (SXT) to study the development of 19 TCH events obtained in a survey of 9 years of Yohkoh observations. We find that the boundaries of the TCHs are never static. The boundaries closer to the magnetic neutral line generally move away from it as the closed-loop X-ray arcades expand. In addition, previously closed coronal loops at the ends of the arcades often continue to expand and open on the outer boundaries of the TCHs. These processes typically last for hours. The arcade brightenings do not extend into the full areas of the TCHs. The TCHs tend to disappear only by a net contraction of the boundaries, rather than by brightening within their boundaries. The location of a TCH appears to coincide with a large-scale curvature of the magnetic neutral line or the occurrence of a nearby active region at one end of the coronal eruption. This distinguishes the formation of TCHs from the arcade development, suggesting that there is no requirement for a pair of TCHs or even any TCH to be formed in an eruptive event. The moving magnetic boundaries, uniformly dark interiors, and short lifetimes of TCHs pose significant problems for the interpretation that TCHs are footpoints of interplanetary magnetic flux ropes.
Mesoscale Data Assimilation for a Local Severe Rainfall Event with the NHM–LETKF System

AbstractThis study seeks to improve forecasts of local severe weather events through data assimilation and ensemble forecasting approaches using the local ensemble transform Kalman filter (LETKF) implemented with the Japan Meteorological Agency’s nonhydrostatic model (NHM). The newly developed NHM–LETKF contains an adaptive inflation scheme and a spatial covariance localization scheme with physical distance, and it permits a one-way nested analysis in which a finer-resolution LETKF is conducted by using the output of an outer model. These new features enhance the potential of the LETKF for convective-scale events. The NHM–LETKF was applied to a local severe rainfall event in Japan during 2012. Comparison of the root-mean-square errors between the model first guess and analysis showed that the system assimilated observations appropriately. Analysis ensemble spreads indicated a significant increase around the time torrential rainfall occurred, implying an increase in the uncertainty of environmental fields.
A CNN-LSTM Car-Following Model Considering Generalization Ability

To explore the potential relationship between the leading vehicle and the following vehicle during car-following, we proposed a novel car-following model combining a convolutional neural network (CNN) with a long short-term memory (LSTM) network. Firstly, 400 car-following periods were extracted from the natural driving database and the OpenACC car-following experiment database. Then, we developed a CNN-LSTM car-following model, and the CNN is employed to analyze the potential relationship between the vehicle’s dynamic parameters and to extract the features of car-following behavior to generate the feature vector. The LSTM network is adopted to save the feature vector and predict the speed of the following vehicle. Finally, the CNN-LSTM model is trained and tested with the extracted car-following trajectories data and compared with the classical car-following models (LSTM model, intelligent driver model). The results show that the accuracy and the ability to learn the heterogeneity of the proposed model are better than the other two. Furthermore, the CNN-LSTM model can accurately reproduce the hysteresis phenomenon of congested traffic flow and apply to heterogeneous traffic flow mixed with adaptive cruise control vehicles on the freeway, which indicates that it has strong generalization ability.
Forecast Advisory for the Late Fall Heavy Rainfall/Flood Event in Central Vietnam Developed from Diagnostic Analysis

AbstractThe formations of heavy rainfall/flood (HRF) events in Vietnam are studied from diagnostic analyses of 31 events during the period 1979–2009. HRF events develop from the cold surge vortices formed around the Philippines. These vortices’ speed, size, and rainfall, which evolve into HRF events, are enhanced distinguishably from non-HRF vortices, as they reach Vietnam. The HRF cyclone, the North Pacific anticyclone, and the northwestern Pacific explosive cyclone simultaneously reach their maximum intensities when the HRF event occurs. An HRF cyclone attains its maximum intensity by the in-phase constructive interference of three monsoon (30–60, 12–24, and 5 days) modes identified by the spectral analysis of zonal winds. The rainfall center of an HRF event is formed and maintained by the in-phase constructive interference of rainfall and convergence of water vapor flux anomalies, respectively, from three monsoon modes. Forecast times of regional models are dependent and constrained on the scale of the.
Free-space optical communication beam acquisition and tracking optimization with 8-segments PSD and small spot size

For Free Space Optical Communication (FSOC) systems, employed on moving platform or communicating with a moving remote terminal, the quality of the communication channel strongly depends upon the tracking performance. In these systems quadrant Position Sensitive Detectors (PSD) are commonly used for beam tracking. This paper presents the results of significantly improved performance in acquisition and tracking of the FSOC system using a custom made 8-segments PSD and minimizing the tracking spot size on the detector.
Response of a single-crystal diamond detector to fast neutrons

Bi-parametric (neutron time of flight and deposited energy) measurements using a Single-crystal Diamond Detector (4.5 × 4.5 × 0.5 mm3 active volume) were performed at the n_TOF neutron facility at CERN. The time structure of the neutron beam combined with the long flight path allowed for measurements of the diamond detector response to quasi monoenergetic neutrons in the energy range up to 40 MeV. Deposited energy spectra were compared to MCNPX simulations using different cross section libraries. The results can be used for the interpretation of Single-crystal Diamond Detector measurements of fast neutrons at spallation neutron sources.
The Study of Bundling Effects on Carbon Nanotubes GM Pressure Coefficients via ODA Functionalized Tubes

The study of carbon nanotubes(CNTs) G-Mode(GM) pressure coefficients, reflecting the stiff sp bond pressure dependence, is essential to the understanding of their extraordinary mechanical properties as well as fundamental mechanics. However, it is hindered by the availability of CNTs samples only as bundles or isolated with surfactants. Octadecylamine(ODA) functionalized CNTs are mostly of a single diameter and can be stably dispersed in 1, 2dichloroethane(DCE) and chloroform. Here we perform high pressure Raman spectroscopy on these tubes and obtain their experimental GM pressure coefficients, which are unaffected by surfactants, for individual CNTs and bundles. The G pressure coefficient for bundles is only about half of that for individual CNTs in DCE and is about two-thirds in chloroform. For bundles, the G− pressure coefficient is about one-third of G in DCE and about the same in chloroform. These results are beyond the framework of the current understanding on the GM pressure dependence.
Transcriptomic Analysis Provides Novel Insights into the Heat Stress-Induced Response in Codonopsis tangshen

Codonopsis tangshen Oliv (C. tangshen) is a valuable traditional Chinese medicinal herb with tremendous health benefits. However, the growth and development of C. tangshen are seriously affected by high temperatures. Therefore, understanding the molecular responses of C. tangshen to high-temperature stress is imperative to improve its thermotolerance. Here, RNA-Seq analysis was performed to investigate the genome-wide transcriptional changes in C. tangshen in response to short-term heat stress. Heat stress significantly damages membrane stability and chlorophyll biosynthesis in C. tangshen, as evidenced by pronounced malonaldehyde (MDA), electrolyte leakage (EL), and reduced chlorophyll content. Transcriptome analysis showed that 2691 differentially expressed genes (DEGs) were identified, including 1809 upregulated and 882 downregulated. Functional annotations revealed that the DEGs were mainly related to heat shock proteins (HSPs), ROS-scavenging enzymes, calcium-dependent protein kinases (CDPK), HSP-HSP network, hormone signaling transduction pathway, and transcription factors such as bHLHs, bZIPs, MYBs, WRKYs, and NACs. These heat-responsive candidate genes and TFs could significantly regulate heat stress tolerance in C. tangshen. Overall, this study could provide new insights for understanding the underlying molecular mechanisms of thermotolerance in C. tangshen.
First direct magnetic field measurements of an asteroidal magnetic field: DS1 at Braille

Deep Space 1 (DS1) is the first interplanetary spacecraft (s/c) using ion propulsion and aims at investigating the compatibility of innovative technology with scientific measurements. DS1 performed a successful flyby at the asteroid Braille on July 29th, 1999. This closest‐ever encounter allowed for the first time a direct measurement of an asteroidal magnetic field. The manifold magnetic disturbances caused by the ion propulsion onboard DS1, however, required an elaborate data processing scheme in order to extract the magnetic signature of Braille. Its successful application to the magnetometer data of the asteroid flyby reveals a magnetic moment of 2.1 · 1011Am² for Braille.
Morphology and Phylogeny of Lyophylloid Mushrooms in China with Description of Four New Species

The lyophylloid agarics are a group of ecologically highly diversified macrofungi, some of which are very popular edible mushrooms. However, we know little about lyophylloid species diversity in China. In this study, we described four new species from China: Lyophyllum atrofuscum, L. subalpinarum, L. subdecastes, and Ossicaulis sichuanensis. We conducted molecular phylogenetic analyses of Lyophyllaceae based on the nuclear ribosomal RNA gene (nLSU) and the internal transcribed spacer regions (ITS). Phylogenetic analyses by the maximum likelihood method and Bayesian inference showed that the four new species are unique monophyletic species. A key to the species of Lyophyllum from China and a key to Ossicaulis worldwide were given.
Loan Moratorium Announcements and Stock Market Reaction: An Event Study Analysis

Moratorium pinjaman telah menjadi talian hayat yang amat penting bagi ramai peminjam semasa pandemik COVID-19. Walaupun sejumlah besar dana telah diperuntukkan untuk membantu peminjam yang terjejas, kesan moratorium pinjaman terhadap bank masih tidak terjawab. Kajian ini bertujuan untuk mengkaji kesan pengumuman moratorium pinjaman terhadap saham bank Malaysia. Dengan menggunakan metodologi event study, kajian ini menunjukkan bahawa pelabur bank bertindak balas secara berbeza terhadap jenis moratorium pinjaman yang berlainan. Pelabur bank menyambut baik moratorium yang tidak mengetepikan faedah terakru dan meliputi kumpulan peminjam yang lebih luas. Kajian ini mencadangkan bahawa walaupun moratorium perlu diberikan kepada peminjam semasa mereka menghadapi kesukaran, kepentingan kewangan bank juga perlu dipertimbangkan. Oleh itu, moratorium pinjaman perlu disertakan pembayaran faedah terakru untuk memastikan prospek bank kekal stabil dari sudutpandangan pelabur.Alternate :Loan moratoriums have been a crucial lifeline defence for many borrowers during the unprecedented COVID-19 pandemic. Despite the massive amount of funds allocated to support affected borrowers, the impact on banks remains unexplored. This study aims to examine the impact of the loan moratorium announcements on Malaysian banks ' stocks. Utilising an event study methodology, this study shows that bank investors reacted differently to different types of loan moratoriums. Bank investors positively valued moratoriums that did not waive accrued interest and covered a broader group of borrowers. This study suggests that while moratoriums must be given to borrowers during difficult times, the financial interests of banks should also be considered. Hence, loan moratoriums should feature accrued interest payments to ensure the banks ' prospects remain stable from the investors' perspective.
Neighborhood Socioeconomic Status and Women’s Mental Health: A Longitudinal Study of Hurricane Katrina Survivors, 2005–2015

There is limited knowledge on the relationship between neighborhood factors and mental health among displaced disaster survivors, particularly among women. Hurricane Katrina (Katrina) was the largest internal displacement in the United States (U.S.), which presented itself as a natural experiment. We examined the association between neighborhood socioeconomic status (SES) and mental health among women up to 10 years following Katrina (N = 394). We also investigated whether this association was modified by move status, comparing women who were permanently displaced to those who had returned to their pre-Katrina residence. We used hierarchical linear models to measure this association, using data from the American Community Survey and the Gulf Coast Child and Family Health study. Neighborhood SES was created as an index which represented social and economic characteristics of participants’ neighborhoods. Mental health was measured using mental component summary (MCS) scores. Increased neighborhood SES was positively associated with mental health after controlling for age, race/ethnicity, economic positioning, time, and move status (19.6, 95% Confidence Interval: 5.8, 33.7). Neighborhood SES and mental health was also modified by move status. These findings underscore the need to better understand the impacts of socioeconomic conditions and health outcomes among women affected by natural disasters.
Whole-fornix endoscopic submucosal dissection for gastric mucosal adenocarcinoma

A 69-year-old man with a history of radiation therapy for gastric malignant lymphoma had undergone follow-up esophagogastroduodenoscopy (EGD) at a previous institution, and a superficial elevated lesion was found at the fornix. Examination of a biopsied specimen revealed well-differentiated adenocarcinoma. Endoscopic submucosal dissection (ESD) was attempted, but the procedure was stopped because Mallory–Weiss syndrome occurred in and around the lesion during endoscopic observation immediately before starting ESD. The patient was then referred to our hospital for further treatment. EGD at our institution revealed a huge superficial lesion occupying the whole fornix (▶Fig. 1). As no evidence of invasive cancer was found, we performed endoscopic resection. A multi-bending two-channel scope (GIF-2TQ260M; Olympus Medical Systems, Tokyo, Japan) was used because this device can closely approach the fornix. We performed traction-assisted ESD using the clip-and-line technique [1–4]. After performing a mucosal incision on the anterior side of the lesion using a FlushKnife BT (DK2618JB15; Fujifilm Medical, Tokyo, Japan) and an ITknife2 (KD-611L; Olympus Medical Systems), we grasped the anterior side of the specimen with the clip-and-line technique. The dissecting plane of the submucosal layer was distinctly observed by pulling the line (▶Fig. 2), and submucosal dissection was then easily performed. After creating a circumferential incision, a second clip-and-line procedure was applied to facilitate submucosal dissection of the anterior wall [5] (▶Fig. 3). Perforation occurred during dissection, but the defect was promptly closed by endoscopic clipping. Using a third clip-andline procedure on the greater curvature side of the specimen, the specimen was resected en bloc (▶Fig. 4, ▶Fig. 5). The pathological diagnosis of the resected specimen was an intramucosal adenocarcinoma with a diameter of 110×48mm.
Photometric studies of stars in ORI OB1 (belt)

Intermediate infrared and (V-I) photometry is presented for 14 reddened B- and A-type stars in Ori OB1 (Belt). From a color-difference analysis, R (the ratio of total-to-selective absorption) is found to be uniform across the subgroup, and calculated to be 3.1 +- 0.2. One star (HD 38087) does exhibit an abnormal reddening law which is probably due to the presence of an optically thin shell of circumstellar material. From UBV observations for 152 B- and A-type stars with no prior available three-color photometry, and existing UBV photometry for 203 additional B- and A-type stars, a variation in distance moduli of 0/sup m/. 2 +- 0/sup m/. 1 is observed between the stars in the Eastern part and those in the remainder of the Belt. The resultant H--R diagram shows that stars with (B-V)/sub 0/approx. =+0/sup m/. 3 still follow the ZAMS, which implies an age of at least 15 x 10/sup 6/ years. As the brighter stars must be much younger, this indicates that star formation in Ori OB1 (Belt) was a continuous process. From the ZAMS fitting method, an intrinsic distance modulus of 8/sup m/. 3 +- 0/sup m/. 4 is derived.
On the Non-Equilibrium Density of Geometric Mean Reversion

The geometric mean reversion process X([dot operator]) is well known to play a fundamental role in economic dynamic models. While it is known, at least sinceÂ Merton (1975), that the equilibrium distribution of geometric mean reversion, i.e. the distribution of X([infinity]), is a gamma distribution, an explicit expression for the non-equilibrium distribution, i.e. the distribution of X(t) for t
Effect of Fabrication Parameters on the Characteristics of Fresnel Lens and Piezoelectric Transducers

A two-mask fabrication process of a four-level Fresnel lens was used to evaluate its characteristics through investigating the effect of SU-8 photoresist on the profile of the focusing lens. A two-step deposition of ZnO films was applied to develop a feasible fabrication of a piezoelectric transducer with the structure Al/ZnO/Pt/Ti/SiO2/Si under reasonable conditions, which include deposition pressure of 0.7 Pa and 1.3 Pa, RF power of 100 W and 178 W, and sputtering gas ratio Ar:O2 = 1:3 and 1:1 for first and second step deposition, respectively. Highly c-axis textured ZnO films were successfully obtained through two-step deposition process.
