A 5-mm Untethered Crawling Robot via Self-Excited Electrostatic Vibration

The grand challenge toward the miniaturization of untethered robots is the lack of a proper actuation system that can effectively transform the limited onboard energy into an untethered movement of the whole body. Here, in this article, we present an insect scale, 5-mm-long, and 9.4 mg in body mass untethered crawling robot powered by a 37 mg onboard ceramic capacitor. With high electromechanical efficiency by utilizing self-excited electrostatic vibration, the prototype device can be directly powered by an onboard capacitor without any boost or frequency conversion circuitry, and forward movements have been achieved at an average moving speed of 5.9 mm/s for 1.68 s. The maneuverability of locomotion from solid ground to water and different moving directional controls via the leg designs have been demonstrated for the advancements in the field of millimeter-scale robotics research.
Numerical investigation to predict fatigue damage response in high-modulus asphalt mixture: a coupled damage-visco-elastoplastic approach

ABSTRACT In this paper, fatigue response under cyclic loading of a high-modulus asphalt mixture (EME14) is numerically investigated based on a coupling approach between damage mechanics and visco-elastoplasticity. The DBN (Di Benedetto-Neifar) model along, an isotropic damage, and a fatigue damage law are adopted to implement both visco-elastoplastic and damage constitutive equations. A set of laboratory experiments are conducted to calibrate the numerical model parameters. In the small deformation domain, complex modulus test results (complex modulus and viscosity) were experimentally fitted based on the 2S2P1D model. Direct tension parameters (stress levels in tension and in compression) were identified through the Di Benedetto viscoplastic criterion. Then, the experimental results of the fatigue test were interpreted to evaluate the damage amount associated with each cycle N and accordingly processed by the DGCB method, developed at the ENTPE (École Nationale des Travaux Publics de l’Etat), to eliminate parasitic effects commonly present in fatigue tests. Hence, a MATLAB program was implemented for uniaxial tension and compression load to estimate damage and fatigue modulus. The consistency between the numerical model outcomes and the experimental measurements showcased the capability of our coupling approach to accurately predict fatigue response under cyclic loading of a high-modulus asphalt mixture (EME14).
Public responses to COVID-19 information from the public health office on Twitter and YouTube: implications for research practice

ABSTRACT We collected tweets directed at the official Twitter account of the Canadian Public Health Office as well as comments on a Canadian Public Health Office press conference posted to YouTube. We used a mixed method corpus-assisted discourse analysis approach to categorize and analyze these data. We found key differences between comments on each platform, namely differences in tone and sarcasm in YouTube comments, and more balance in Twitter mentions. Findings suggest that studying public responses to health information on one platform in isolation does not provide an accurate picture. To generate a fuller picture of misinformation, researchers should conduct studies across digital platforms using diverse methods. This research could influence how studies of health communication and public opinion are approached in the future.
Popular culture at work: how emerging adults’ favorite celebrity can influence future career aspirations and work ethic

ABSTRACT The influence of celebrities on career aspirations has received little attention in vocational anticipatory socialization research. Two studies examined the potential role of a favorite celebrity or fictional character on emerging adults’ career aspirations and work ethic. Differences in celebrity versus fictional characters were examined. Both homophily and wishful identification predict the influence of celebrities and fictional characters on career aspirations. Additionally, wishfully identifying with celebrities was found to significantly predict participant work ethic.
Love mode surface acoustic wave and impedance sensors for water toxicity sensing

Clean water supply systems and infrastructure require periodic testing of water samples to maintain water quality. To enable this, toxicity tests need to be rapid, accurate, portable, and low cost to provide affordable water security especially in developing countries. Qualitative and quantitative measurement of contaminants in water is classically done by standard analytic chemical methods, which are time‐consuming, labor‐intensive, expensive, and cannot be performed easily outside the laboratory. An alternative to these methods is cell‐based sensors, which can detect the presence of a wide range of toxicants by monitoring the cell states.
Synthesis and characterization of vanadium doped TiO2 for the visible light-driven photocatalytic activity

V-doped TiO2 nanoparticles (NPs) was synthesized by a sol-gel hydrolysis method using titanium butoxide (Ti(OBu)4) and vanadyl acetylacetonate (VO(acac)2) as a precursor and dopant, respectively. The effects of different V : Ti ratios on the crystal structure, band gap energy and photocatalytic activity have been investigated. The photocatalytic activity of V-doped TiO2 NPs was evaluated using UV-vis absorption spectroscopy through degradation of a methyleneblue (MB) solution under visible light irradiation. Characterization by Raman and X-ray diffraction pattern shows that V was doped effectively and oxygen vacancies and various defects or Ti3+ centers were formed. Energy dispersive X-ray (EDX) and X-ray photoelectron spectroscopy (XPS) results indicated the presence of V in the TiO2. The band gap energy of V-doped TiO2 NPs was determined to be 2.3 eV, with a distinct red-shift confirmed by diffuse reflectance spectroscopy (DRS). The photocatalytic activity of V-doped TiO2 NPs exhibited highly enhanced visible-light-induced photocatalytic performance compared with pure TiO2 NPs.
The effects of a multimodal music program on young children’s facial expressions during controlled singing tasks

Understanding children’s emotional perceptions of creative tasks can contribute to the optimal design of music programs. Little is known of how young children perceive vocal tasks, and whether music training changes their emotional perceptions. This research examined children’s facial expressions while performing vocal imitation and improvisation tasks before and after music training. Young children (N=79) aged four to six years were randomly assigned to a multimodal music program, Lego training, or a no-treatment control group. Their facial expressions while performing the tasks were analyzed, and learning outcomes were assessed by measuring participants’ pitch accuracy and improvisation skills at pre-and post-training. The results yielded no significant differences among the groups’ facial expressions. There was, however, a significant main effect of time such that participants showed more Surprise while performing vocal improvisation tasks. While participants in the multimodal music program scored higher on measures of pitch accuracy and improvisation skill, it may be necessary to increase the duration of early childhood music programs to reduce their feelings of apprehension when performing vocal improvisation tasks.
Stapedotomy for fenestral otosclerosis: long term audiovestibular outcomes and complications

Abstract Objectives Otosclerosis is a progressive disease of the otic capsule characterised by disordered bone remodelling with abnormal resorption and neoformation of the temporal bone. Fenestral (or stapedial) otosclerosis is the most frequent form, when the focus of demineralisation involves the stapes footplate and the oval window. Stapedotomy and stapedectomy are indisputably the two main stapes surgery techniques for otosclerosis. The aims of this article are to evaluate the outcome of stapedotomy in terms of long-term audiological results and possible onset of late audiovestibular complications. Methods This retrospective study included 63 patients who underwent primary stapedotomy for treatment of conductive hearing loss due to otosclerosis with more than 15 years postoperative follow-up. Results We compared the preoperative results with the long-term stapedotomy results and observed an improvement of the pure tone average (PTA) for air conduction (AC) of 10.6 ± 7.6 dB and an average air/bone gap (ABG) improvement of 22.6 ± 5.7 dB. A surgical revision was necessary in two cases (3%). Complications included tinnitus in 5 cases and a temporary hypogeusia in two patients (3%); in the immediate postoperative period, 6 patients (10.2%) complained of vertigo. Conclusions Our results provide further evidence of the validity of stapedotomy as the reference technique for the surgical treatment of fenestral otosclerosis.
Effect of Supervision on the Actions of Implementing Nurses in the Implementation of Patient Safety at PTPN IV Kebun Laras Hospital, Simalungun Regency

The goal of patient safety is one of the requirements that must be applied to the patient safety program in all hospitals. The implementation of patient safety programs is influenced by behavioral factors, namely the actions of nurses. The implementation of patient safety goals at PTPN IV Kebun Laras Hospital, Simalungun Regency is still not maximally implemented, seen from the actions of nurses, namely there are still incidents that endanger patients (KTD and KNC), and not all nurses behave in accordance with SOPs in implementing patient safety goals. The research used observational analytic method with cross sectional design. The samples were 62 nurses. The results showed that supervision variable had an effect on the actions of implementing nurses in the implementation of patient safety at PTPN IV Kebun Laras Hospital, Simalungun Regency. Keywords: Supervision, Nurses, Patient Safety.
Outcome after total knee arthroplasty with or without patellar resurfacing

Background: Patellar resurfacing in total knee arthroplasty has had its defenders and detractors. There seems to be a great difference in patellar resurfacing between countries and patellar resurfacing is still controversial. Some surgeons resurface the patella routinely, others not at all, and a third group prefers selective resurfacing. Therefore, in this prospective and randomised study, we compared the outcome after total knee arthroplasty with or without patellar resurfacing.Methods: In this study 50 cases (100 knees) were selected and each case was followed up for 2 years. In each case, one knee was operated by TKA with patellar resurfacing and the other by TKA with patellar non-resurfacing. Patients were followed-up for a period of 2 years and clinical and functional outcome of both knees was measured and compared by the help of knee society score (KSS) and VAS score.Results: There was statistically significant difference between the patellar resurfacing and non-resurfacing group with regard to knee society score, pain score and visual analogue score (VAS), with the patellar resurfacing having better scores. There was no significant difference in the functional scores between the 2 groups. Range of motion was complication rate was comparable in both the groups. However, there was no case of reoperation nor was there any complication related to the patellar implant. Conclusions: Patellar resurfacing in TKA leads to less post-operative persisting knee pain, and also leads to better outcome in terms of walking without pain, using stairs without pain and rest pain as compared to TKA without patellar resurfacing.
DAN‐Conv: Depth aware non‐local convolution for LiDAR depth completion

Sparse LiDAR depth completion is a beneficial task for many robotic applications. It commonly generates a dense depth prediction from a sparse depth map and its corresponding aligned RGB image. This image-guided depth completion task mainly has two challenges: sparse data processing and multi-modality data fusion. In this letter, they are dealt with by two novel solutions: (1) To efficiently process sparse depth input, a Depth Aware Non-local Convolution (DAN-Conv) is proposed. It augments the spatial sampling locations of a convolution operation. Specifically, DAN-Conv constructs a non-local neighbourhood relationship by exploiting the intrinsic correlation among observable depth pixels. In particular, it can readily replace standard convolution without introducing additional network parameters. (2) A Symmetric Co-attention Module (SCM) is proposed to fuse and enhance features from depth and image domain. It estimates the importance of complementary features by the co-attention mechanism. Finally, a neural network built on DANConv and SCM is proposed. It achieves competitive performance on the challenging KITTI depth completion benchmark. Comparing to approaches with approximate accuracy, this lightweight network requires significantly fewer learnable parameters.
How Celebrity Endorsement Influences Consumer’s Purchase Intention of Fashion Products on Instagram

This purpose of this study is to assess the effectiveness of celebrity endorsement in marketing fashion products on social media in Indonesia. This study examines five attributes: familiarity, congruity, physical appearance, trustworthiness, and expertise. Research was conducted using the quantitative method with analytic observation and cross-sectional studies. Data obtained were managed descriptively and analytically using SPSS with multiple regression analysis. The result of our regression analysis showed three attributes that positively impact consumer’s purchase intention; familiarity with the celebrity, trustworthiness of the celebrity; and the expertise of the celebrity in giving recommendation. This quantitative study was conducted with a small number of samples, using a specific celebrity and product type. Studies using different celebrities and product categories may have different outcomes. Therefore, we cannot generalized the result of this study given the said limitation. This research was conducted to help management choose the right marketing tool and the best celebrity based on the result of this study to help management meet their marketing strategy objectives.
The affordances of PAR for a school-community partnership to enhance learner support in socio-economically challenged communities

Although complex reasons exist for the poor state of education in socio-economically challenged communities in South Africa, improving parental support to learners is one approach to buffer contextual adversities. Yet, historically, collaboration between school and parent has been problematic. We hypothesized that a participatory action research approach might be useful to develop positive relations between teachers and parents. We report on the benefits of a PAR project undertaken by seven community parents and five teachers to enhance learner support in a primary school situated in a low-income area. Thematic analysis of focus group interviews with participants, triangulated by transcriptions of a final project workshop, revealed that participation in the PAR process enabled i) the development of contextually relevant content for an educational programme; ii) change in the assumptions of parents and teachers about their respective roles in supporting the child; iii) the personal/technical skills development of participants; and iv) positive outcomes beyond the project. The insights gain from this study highlight the benefits of PAR to enable schools to harness the wealth of knowledge and skills that exist in their community to enhance learner support and improve the quality of teaching and learning.
Spatiotemporal Variations of Spring Indices in China and Their Physical Mechanisms

Spring indices refer to the onset date of Spring, which quantify the phenological events in Spring. The average spring index (Avg‐SI) is defined as the average of the first leaf index (the date of early spring) and the first bloom index (the date of late spring) in this study. This study calculated the Avg‐SI in China for 2,780 weather stations during 1951–2014. The long‐term mean Avg‐SI suggested that the spring onset gradually delayed with the increase of latitudes and altitudes. The long‐term trend indicated earlier onset of spring in nearly all sub‐regions in China. The spatiotemporal variations of Avg‐SI were analyzed using the empirical orthogonal functions (EOF) method. The first EOF mode suggested a homogenous pattern across China. This mode is closely linked to the Atlantic Multidecadal Oscillation (AMO), which impacts the atmospheric circulation and temperature across Eurasia. Warm phase of AMO is associated with positive geopotential height (HGT) anomalies and warmer spring in China. The second EOF mode suggested a north‐south zonal pattern, which is linked to the Arctic Oscillation (AO) and the East Asian Trough Strength. Positive phases of AO lead to positive HGT anomalies over the northern China but negative HGT anomalies over the southern China. Together they lead to a weaker East Asian Trough and less cold air intrusions to the northern China, which in turn cause earlier onset of spring in this region.
Conjugated Oligomers as Fluorescence Marker for the Determination of the Self-Healing Efficiency in Mussel-Inspired Polymers

Within the current study, a novel approach for the detailed determination of the scratch healing efficiency in mussel-inspired polymer films is presented. For this purpose, a sensor molecule was incorporated into a self-healing polymer network based on reversible zinc–histidine interactions. The fluorescence of the sensor molecule was monitored enabling a detailed depth- and time-resolved determination of the healing efficiency by means of confocal laser scanning microscopy (CLSM). Finally, this concept represents an efficient and detailed approach for the determination of the scratch self-healing efficiency in polymer films and can also be applied for other scratch self-healing systems, which are based on reversible dynamic bonds.
Organic matter in carbonaceous chondrite lithologies of Almahata Sitta: Incorporation of previously unsampled carbonaceous chondrite lithologies into ureilitic regolith

The Almahata Sitta (AhS) meteorite is a unique polymict ureilite. Recently, carbonaceous chondritic lithologies were identified in AhS. Organic matter (OM) is ubiquitously found in primitive carbonaceous chondrites. The molecular and isotopic characteristics of this OM reflect its origin and parent body processes, and are particularly sensitive to heating. The C1 lithologies AhS 671 and AhS 91A were investigated, focusing mainly on the OM. We found that the OM in these lithologies is unique and contains primitive isotopic signatures, but experienced slight heating possibly by short‐term heating event(s). These characteristics support the idea that one or more carbonaceous chondritic bodies were incorporated into the ureilitic parent body. The uniqueness of the OM in the AhS samples implies that there were large variations in primitive carbonaceous chondritic materials in the solar system other than known primitive carbonaceous chondrite groups such as CI, CM, and CR chondrites.
Self-assembly of hydroxyapatite with polyelectrolyte as a green flame retardant for poly(vinyl alcohol)

Here, we present a multifunctional bio-based polyelectrolyte multilayer-coated hydroxyapatite (HAP@CS@LSF) as a green flame retardant through layer-by-layer inspired assembly using hydroxyapatite, chitosan, and lignosulfonate. The electrostatic interactions deposited the chitosan/lignosulfonate coating on the surface of hydroxyapatite. Subsequently, this multifunctional flame retardant was used to enhance thermal properties, flame retardancy, and mechanical properties of poly(vinyl alcohol). The addition of HAP@CS@LSF to poly(vinyl alcohol) thermally stabilized the poly(vinyl alcohol) composites and resulted in a higher char yield. Furthermore, hydroxyapatite played a critical role and generated synergies with chitosan and lignosulfonate to improve fire safety of poly(vinyl alcohol). Meanwhile, the poly(vinyl alcohol) composites exhibited superior enhancements in tensile strength than that of pure poly(vinyl alcohol).
PERFORMANCE BANK BNI SYARIAH DI MASA PANDEMI COVID-19

The performance of Islamic banks during the Covid-19 pandemic has had an impact on the financial soundness of Islamic Banks. Islamic Banks in Indonesia should restructure the Financing (PYD) which results in the acquisition of revenue and net profit received by the bank. The aims of this study are to analyze the soundness of Bank BNI Syariah using the CAMEL, RGEC method, the level of cost efficiency and profitability. Then also measured the potential for BNIS bankruptcy with the Altman Z-Score model. The potential risk of bankruptcy in Islamic Banks is very possible if bank management during the Covid-19 pandemic are not carried out properly and professionally. Secondary data is used during the period 2015 to 2020 to analyze the performance of Islamic Banks before the pandemic and during the pandemic. The results of the CAMEL and RGEC analysis show that soundness conditions varied from "Not Very Good" to "Very Good" from 2015 to 2020. In 2020 the soundness condition of BNIS is "Fairly Good". Meanwhile, the Altman Z-Score shows that BNIS is experiencing a “Not Bankrupt” condition, the level of bank efficiency is “High” and at analysis of profitability as reflected by the ROA ratio, ROE during the pandemic has decreased.
Assessment of rice threshing technology characteristics for enhanced rice sector development in Senegal

Understanding the technology characteristics desirable to farmers to increase the adoption of improved technologies remains a high-priority research issue in sub-Saharan Africa (SSA). The study aimed to quantify farmers’ demand and assessment of the characteristics of rice threshing technologies to enhance the adoption of innovations in Senegal. A multistage sampling technique was used to collect primary data from 318 rice farmers in the Senegal River Valley. Three indexes (demand, supply and attainment) of technology characteristics were estimated to assess farmers’ perceptions of the characteristics of three threshing techniques (traditional, ASI thresher and combine harvester-thresher). The results showed that of the eleven selected characteristics, time savings (0.95), labour savings (0.94) and grain quality (0.93) were farmers’ key demand. The ASI thresher and combine harvester-thresher met farmers’ needs well in terms of the attributes of grain quality and production capacity. However, users of the traditional technique reported low levels of perceived usefulness, and users of the combine harvester-thresher reported low levels of ease of use. Women labour usefulness is a trade-off for advancement in threshing technologies in pursuance of rice sector improvement, implying that efforts towards developing gender-friendly threshers are required. The variables estimated in this study offer policy considerations for development of the rice production system in Senegal. The originality of this paper is its use of a combination of take-the-best theory, the technology acceptance model and an indexing approach to reveal specific characteristics for the development of best-fit mechanization equipment, mainly improved threshers for rice sector development in SSA.
