Abstract
Owing to the intermittent and randomness of solar radiation, high-penetration photovoltaic (PV) energy injected into power distribution systems will inevitably change the magnitude and direction of the power flow, thus causing problems such as voltage violation of the point of common coupling (PCC) and further having a hazardous influence on consumers’ electricity quality. And the communication construction of China’s distribution systems is now relatively weak, difficultly integrating multiple voltage regulation equipment. To improve consumers’ voltage quality at the PCC, a coordinated control method based on active and reactive power of local inverter is proposed. This method can realize the economic regulation of the voltage at the PCC through reactive compensation and active reduction, which can maximumly assure the voltage magnitude at the PCC within limits (including upper and lower limits) and maximize the utilization capacity of PV inverter. Based on Matlab/Simulink, simulation results in different scenarios show the effectiveness of the proposed method.

Abstract
In the weld quality inspection system based on machine vision and computer image processing, according to the principle of laser triangulation, a line laser is used to project structured light on the weld surface, and the weldment moves uniformly in a straight line on the moving platform. At the same time, the CMOS camera captures the structured light image and transmits it to the industrial computer through Gigabit Ethernet. The image is denoised by the median filtering algorithm on the industrial computer, then the image is segmented by the maximum inter-class error (Otus) method, and the image is binarized according to the threshold value. Then the center of the stripe is extracted by constructing four direction templates, and the 3D model is reconstructed by curve fitting. After the completion of the image processing, the geometric size of the weld is measured by mathematical formula. After the weld seam measurement is completed, the weld seam is transversely cut off at the same position, measured by manual method, and then the data measured by the two methods are compared. Through repeated measurements and comparisons of weld width, residual height and back forming, the precision of the system meets the practical requirements. The weld forming varies with the welding parameters within a certain range, but changes little and has good stability.

Published: November 2019

Abstract
For the large variety of shopping malls, supermarkets, cafeterias and other places, customers need to spend a lot of time looking for goods. Due to this, a smart shopping guide is designed based on PLC. The robot mainly uses the CPU 224 controller to control the motor to drive at a speed of 1 m/s, and the DC brushless motor can load 75 kg of goods at a constant speed. If the distance between the pedestrian and the robot exceeds the allowable range, the CPU will execute the interrupt program and the robot will stop moving to avoid the pedestrian until the pedestrian completely walks out of the maximum allowable range. The sensor could not detect the pedestrian, and the CPU controlled robot continued to work. After testing, this robot can reduce the time spent by customers in finding goods, which greatly saves manpower and material resources.

Abstract

BACKGROUND
Previous studies implicated cardiotonic steroids, including Na/K-ATPase inhibitor marinobufagenin (MBG), in the pathogenesis of preeclampsia (PE). We demonstrated that MBG induces fibrosis via mechanism involving inhibition of Fli1, a nuclear transcription factor and a negative regulator of collagen-1 synthesis. We hypothesized that PE blockade of increased MBG with antibody would lessen the fibrosis of umbilical arteries and lower the blood pressure in rats with PE.

METHODS
We tested 36 pregnant Sprague-Dawley rats in which 12 were made hypertensive by 1.8% Na supplementation (days 6–19 of gestation), 12 pregnant rats served controls. At day 19, PE rats received one intraperitoneal injection of polyclonal anti-MBG-4 antibody (0.5 ug/ml) for 4 hours.

RESULTS
PE was associated with higher blood pressure (117 ± 2 vs. 107 ± 2 mm Hg; P &lt; 0.01), plasma MBG levels (1.54 ± 0.34 vs. 0.49 ± 0.11 nmol/L; P &lt; 0.01), protein excretion (26 vs. 12 mg/24 hours), sFlt-1 (3-fold), decrease in Fli1 (7-fold) and increase in collagen-1 in aorta (4-fold) vs. control rats (all P &lt; 0.01). In 12 rats treated with polyclonal anti-MBG-4 antibody blood pressure dropped (93 ± 3 mm Hg) and Fli1 was decreased much less (2-fold; P &lt; 0.01 vs. nontreated rats).

CONCLUSIONS
These results demonstrate that in experimental PE elevated MBG level is implicated in umbilical fibrosis via suppression of Fli1.

AbstractBlack rockfish (Sebastes schlegelii) is an economically important viviparous marine teleost in Japan, Korea, and China. It is characterized by internal fertilization, long-term sperm storage in the female ovary, and a high abortion rate. For better understanding the mechanism of fertilization and gestation, it is essential to establish a reference genome for viviparous teleosts. Herein, we used a combination of Pacific Biosciences sequel, Illumina sequencing platforms, 10× Genomics, and Hi-C technology to obtain a genome assembly size of 848.31 Mb comprising 24 chromosomes, and contig and scaffold N50 lengths of 2.96 and 35.63 Mb, respectively. We predicted 39.98% repetitive elements, and 26,979 protein-coding genes. S. schlegelii diverged from Gasterosteus aculeatus ∼32.1-56.8 million years ago. Furthermore, sperm remained viable within the ovary for up to 6 months. The glucose transporter SLC2 showed significantly positive genomic selection, and carbohydrate metabolism-related KEGG pathways were significantly up-regulated in ovaries after copulation. In vitro suppression of glycolysis with sodium iodoacetate reduced sperm longevity significantly. The results indicated the importance of carbohydrates in maintaining sperm survivability. Decoding the S. schlegelii genome not only provides new insights into sperm storage; additionally, it is highly valuable for marine researchers and reproduction biologists.
Learning most with least effort: subtitles and cognitive load
Authors: Baranowska Karolina 
Published: November 2019

AbstractThe article reports a study investigating the effects of different subtitling conditions on cognitive load, incidental vocabulary learning, and comprehension. In the study, 63 Polish intermediate learners of English were asked to watch a movie clip and subsequently to answer comprehension questions, take a vocabulary knowledge test, and fill in a self-reported cognitive load questionnaire. They were divided into three groups: one group watched the clip with Polish subtitles, one with English subtitles, and one without subtitles. The findings indicate that intralingual (L2) subtitles assist learners in vocabulary acquisition more than interlingual (L1) subtitles. Moreover, both types of subtitles lower cognitive load, which is accompanied by greater comprehension of the material presented. The results of the study offer some practical implications for EFL teachers and learners.
Btn2 is involved in the clearance of denatured proteins caused by severe ethanol stress in Saccharomyces cerevisiae
Authors: Kato Sae , Yoshida Masashi , Izawa Shingo 
Published: November 2019

ABSTRACT
Saccharomyces cerevisiae shows similar responses to heat shock and ethanol stress. Cells treated with severe ethanol stress activate the transcription of HSP genes and cause the aggregation of Hsp104-GFP, implying that severe ethanol stress as well as heat shock causes the accumulation of denatured proteins in yeast cells. However, there is currently no concrete evidence to show that severe ethanol stress causes protein denaturation in living yeast cells. In the present study, we investigated whether severe ethanol stress causes protein denaturation, and confirmed that a treatment with 10% (v/v) ethanol stress resulted in the accumulation of insoluble proteins and ubiquitinated proteins in yeast cells. We also found that increased denatured protein levels were efficiently reduced by the ubiquitin–proteasome system after the elimination of ethanol. Since our previous findings demonstrated that the expression of Btn2 was induced by severe ethanol stress, we herein examined the importance of Btn2 in protein quality control in cells treated with severe ethanol stress. btn2∆ cells showed a significant delay in the clearance of denatured proteins during the recovery process. These results provide further insights into the effects of severe ethanol stress on yeast proteostasis and the contribution of Btn2 to the efficient clearance of denatured proteins.

Published: November 2019

Abstract
As one of the world’s fastest aging countries, China’s growing prevalence of Alzheimer’s and related dementias (ADRD) poses concerns among older adults. Lack of knowledge about ADRD and excessive worries about ADRD can cause cumulative stress and threaten physical and psychological well-being of older adults. We conducted a randomized controlled trial to examine the effectiveness of a Brain Fitness Intervention (BFI) on the knowledge and worries about Alzheimer’s at three senior residential care facilities in China. Ninety older adults aged 60 and above underwent randomization. Fifty participants in the intervention group received eight weekly BFI sessions, including Tai Chi exercise, experiential learning, and group discussions. The primary outcomes were the changes from baseline to Week 8 in the scores on the ADRD knowledge scale (ranging 5–50) and worry scale (ranging 5–45). Twenty-seven participants withdrew from the study. Intent-to-treat analysis showed that the estimated mean change in knowledge on ADRD was 4.26 in the treatment group and -1.52 in the control group (p &lt; 0.001). The estimated mean change in worries about ADRD was -10.25 in the treatment group and -2.9 in the control group (p &lt; 0.001). Results remained robust in sensitivity analysis adjusting for study sites and baseline characteristics. Heterogeneity analysis showed that the treatment effect became stronger with the increase of age. Findings support the effectiveness of BFI in increasing ADRD knowledge and reducing worries among Chinese older adults. Future trials with larger sample sizes will be needed for more conclusive results.
MY MESSAGE: CUSTOMIZED VISUAL CUES FOR PERSONS WITH DEMENTIA USING ADAPTIVE DISPLAY TECHNOLOGY
Authors: Skrajner Michael , Zeisel John , Gorzelle gregg , Albright Tom , Gepshtein Sergei 
Published: November 2019

Abstract
The My MESSAGE™ (MM) intervention visually conveys individualized messages to persons with dementia (PWD) on adaptive electronic displays in strategic locations activated by an approaching individual. MM aims to improve quality of life (QoL) and reduce challenging behaviors, especially repetitive questioning and wayfinding difficulties. For example, for a PWD who repeatedly asks when his/her daughter will visit, the monitors display a reassuring message, such as, “I love you and will visit soon.” A PWD who has trouble finding his/her bedroom, receives directions on the monitor. MM was tested in a Phase 1 STTR. The sample consisted of 22 PWD: 10 in Experimental Group (EG) and 12 in Control Group (CG). MM had positive immediate impacts on EG participants, with 100% exhibiting positive affect, 80% reduced agitation, 60% reduced anxiety, and 50% improved mood. MM had positive longer-term/generalized impacts on PWD, as well. For the CG, QoL (based on the Dementia Quality of Life Scale) tended to decline from baseline to post-treatment for the CG (p=0.053); with no decline in the EG. Agitation (based on the Cohen-Mansfield Agitation Inventory) tended to increase in the CG (p=0.057); no change was found in the EG. There was a significant decrease in neuropsychiatric symptoms (based on the Neuropsychiatric Inventory-Nursing Home) for the EG (p=.040); no change was detected for the CG. The results suggest that MM is worthy of further development and evaluation in a planned Phase 2 study.

Published: November 2019

Abstract
Older adults commonly experience disturbed sleep such as difficulty initiating or maintaining sleep. Older adults who experience impaired sleep are at increased risk for cognitive decline or developing Alzheimer’s disease (AD). Research has shown that people with AD experience changes in sleep patterns, however, these changes are not well characterized. To better understand sleep in an older adult population with and without AD, the present study aimed to describe and compare objective sleep characteristics in both. Participants were older adults (126 with and 41 without AD) who wore an ActiGraph GT9X monitor on their non-dominant wrist for 7 days in a free-living environment. Results suggest that, compared to those without AD, participants with AD spent significantly more time in bed, t (165) = -4.37, p = .001), slept for longer durations, t (165) = -2.39, p = .044), and had less efficient sleep, t (165) = 2.71, p = .007. Participants with AD also had significantly greater sleep onset latency, more time awake after sleep onset, longer awakening lengths, and tended to arise later in the morning (all p ≤ .016). No differences were found between the groups in age, bedtime, or the number of awakenings during the night. These findings add to our understanding of the sleep disturbances experienced by older adults with and without AD. Significant group differences suggest that interventions may be necessary in treating sleep disturbances for older adults with and without AD. Future studies should examine sleep longitudinally to understand risk factors related to AD.
TASK-SPECIFIC METACOGNITIVE ACCURACY DECLINES ACROSS THE DEMENTIA-ALZHEIMER’S TYPE SPECTRUM

Abstract
Subjective cognitive complaints (SCCs) remain part of the diagnostic criteria for amnestic mild cognitive impairment (aMCI), the prodromal stage of dementia - Alzheimer’s type (DAT), despite weak relationships between self-reported and objectively-measured functioning. Most metacognitive measures focus on ratings of global retrospective memory rating only; greater subtlety in measurement of SCCs is required. Similarly, it is critical to identify the disease stage at which the clinical utility of SCCs is nullified by impaired insight. This study aims to evaluate group differences in (a) task-specific metacognitive ratings, and (b) the accuracy of these ratings in individuals diagnosed as cognitively intact (CI), with aMCI, or with DAT. 99 older adults (M-age = 69.43, SD-age = 6.98; M-edu = 15.54, SD-edu = 2.47; CI: n = 50, aMCI: n = 34, DAT: n = 15) enrolled in the University of Michigan Memory and Aging Project rated their performance on the Object Location Touchscreen Task (OLTT), an ecologically valid memory measure. One-way analysis of variance (ANOVA) revealed that individuals with aMCI-multiple domain or DAT rated their memory performance similarly to CI individuals, though the aMCI-single domain group rated themselves as more impaired. Bivariate Pearson’s r correlations demonstrated a decline in the strength of the relationship between task-specific metacognitive ratings and actual OLTT memory performance with increasing diagnostic severity. These findings suggest a decline in insight on task-specific memory ratings across the DAT spectrum, and call into question the use of self-reported SCCs as a diagnostic tool in later stages of disease progression.

Published: November 2019

Abstract
To address the characteristics of Alzheimer’s disease and related dementias (ADRD) that complicate end-of-life (EOL), we created and validated a dementia-specific EOL planning instrument. This instrument can be used to facilitate discussions and provide documentation of EOL values and care preferences prior to loss of decisional capacity. Instrument development used a mixed-method design that included: a) conducting a series of focus groups (healthy adults, persons with early-stage ADRD, and dementia caregivers) to develop and confirm content, comprehensiveness, and usability, b) evaluation by content experts to verify instrument utility in clinical practice; and c) conducting a national survey of healthy older adults and adults with early-stage ADRD to evaluate instrument psychometric properties. We describe the expansion of the instrument from survey tool into a user-friendly guide: “The LEAD Guide” or Life-Planning in Early Alzheimer’s and Dementias Guide. We describe the utility of the LEAD Guide for persons planning ahead for the possibility of ADRD, those with MCI and their families, for providers to use with patients and families, and for researchers studying the EOL preferences and values of persons in these populations. Instructions specific to each user group are health literacy appropriate, and include a glossary of terms. Age-friendly graphic design and availability in both print and e-versions enhance utility. The LEAD Guide can be utilized to help inform EOL care decisions and ensure that they align with the patient’s values and may serve as the basis of an intervention to support choice in persons with dementia.
ARE YOU READY FOR CHANGE? FACTORS ASSOCIATED WITH COMMITMENT TO CHANGE IN CLINICAL PRACTICE

Published: November 2019

Abstract
Commitment to Change (CTC) has been shown to be an effective performance measure of continuing professional development (CPD) training, in that 50-67% of providers choosing CTC also made behavioral changes in clinical practice (Domino et al. 2011; Perkins et al., 2007). However, very little is known about the factors that are associated with a learner committing to practice change. This study presents findings from a retrospective observational study that compared trends across various health profession, demographics, and activity-type categories to identify learner characteristics that may lead to higher CTC responses. Learner data from 2014 -2017 was obtained from two different continuing education office databases. The combined dataset contained 68,365 evaluations from 26,508 learners, of which 22.8% wrote a CTC. At both sites, CTC was more likely if the activity was enduring or charged a fee and less likely for an RSS (p&lt;0.001). Results indicate that CTC varies based on provider demographics, such as profession and specialty. Allied health providers (32.4-37.5%) and health educators (36%) were most likely to make a commitment, followed by nurses (28.6%), physicians (23.9%), pharmacists (14.9%), and dentists (9.1%). Physician specialties and provider region also varied with the highest CTC by geriatricians (50%) and occupational medicine providers (42.3%) and the lowest rates of CTC found in the southeast region. Results of the study will help inform the development and implementation of future CPD in order to successfully engage learners in committing to change clinical practices.
