Authors: Xing Bowen , Zhang Lan , Li Cai , Chen Xiao 
Published: July 2021

Abstract
In order to solve the problem of the traditional Canny edge detection algorithm, due to the inaccurate selection of the threshold value, the recognition rate is low in the fish edge detection process. This paper proposes an adaptive Canny edge detection algorithm. The image enhancement is carried out by using automatic color scale, and the optimal recognition of underwater fish target is completed. The experimental results show that the improved algorithm and edge contour are more complete, which proves the effectiveness of the fish density recognition method.

Published: July 2021

Abstract
Mooring system is an important factor affecting the safety and motion law of floating body. It is very important to study the hydrodynamic characteristics of different mooring methods for offshore safety engineering and stability analysis of mooring system. Taking oc4 as a floating body hydrodynamic model and considering the combined action of wind, wave and current, the hydrodynamic characteristics and system stability of taut and catenary mooring mode are compared and analyzed respectively. In addition, the differences and variation rules of dynamic response of floating body under different mooring conditions are explored and summarized. Combined with the time-domain analysis theory and simulation results, the coupled motion equations of taut and catenary mooring system are improved, and the corresponding relationship between slow drift motion and different mooring modes is summarized. It provides an important theoretical basis and support for the research of time domain variation law of mooring system and marine safety control.

Published: July 2021

Abstract
This paper presents new modeling techniques for evaluating the performance of photovoltaic (PV) panels, vertical-axis wind turbines (VAWT), and horizontal-axis wind turbines (HAWT). Two methods are implemented to evaluate and simulate the designed models based on actual data points from various manufacturing manuals. The first technique is based on curve fitting while the artificial neural network (ANN) is the second method. The developed models can predict the operating performance characteristics of PV, VAWT and HAWT based only on the demand power. Hence, it can easily assist the designer to select a suitable unit before the installation process. The PV model can predict the short circuit current, open circuit voltage, voltage and current at maximum power, module efficiency and the module cost for a power range from 5W to 350W per module. Moreover, the wind turbine models can predict the cut-in wind speed, rated speed, rotor diameter, rotor speed, hub height and the turbine cost for a power range of 0.1kW to 100kW for VAWT and from 0.5kW to 8000kW for HAWT. The results show that the ANN method provides a higher match with the actual data compared to the curve fitting method. The models are conducted via Matalb/Simulink.
High-frequency validation of predictions for energy production from large solar PV plants
Authors: Castelletto Stefania , Boretti Alberto 
Published: July 2021

AbstractThe solar energy source is characterized by variability, intermittency, and unpredictability. The annual average direct normal irradiance and global horizontal irradiance only gives a rough estimation of the amount of energy that can be harvested by a solar photovoltaic plant. It is however also relevant to quantify the variability of the energy production, which is not only the result of alternating daylight and night time but also to accept variability from one day to another due to weather and seasonality. A design that permits a more stable controllable output is preferable because it reduces the need for external energy storage by batteries. Here we quantify the coefficient of variability of existing photovoltaic plants, and compare it with the coefficient of variability of the resource, to validate solar PV plant models.

Abstract
Indonesia currently is facing an energy crisis due to depletion of oil reserves and rapid growth in conventional energy consumption. The declining fossil energy potential especially oil and gas has encouraged the government to put new renewable energy (NRE) as the main priority to maintain energy security for national supply in the future. NRE in Indonesia is generated from bioenergy power, hydro power, solar power, tidal power, wind power, and potential. However, NRE utilization in Indonesia is only about 11% from the total potential. This study assesses the hydropower production capacity of Ayung River Basin, the biggest Basin in Province of Bali. The assessment is carried out by utilizing global data that can be easily accessed. It was found that there are several potential mini-hydropower locations around the Ayung River Basin, with the biggest potential is around 2 MW.

Authors: Yanli Sun , Chao Li 
Published: July 2021

Abstract
The “fourteenth fiveyear plan” period is the key period for China to cross the high income threshold and tackle the key problems of reform, and it is also the key period for China to continue to transform the old and new kinetic energy. In this period, the pace of new urbanization in China is gradually accelerating, and it is becoming a powerful engine of China’s economic growth and social development. The new urbanization strategy will leverage a new round of development of the construction industry and become a new growth point of the construction industry. The traditional construction industry is at the cost of consuming a lot of natural resources and causing heavy environmental burden. As a technological innovation with innovative significance in changing the mode of production, prefabricated building is an important way of energy conservation and emission reduction, and its development prospect is very broad. However, due to the relatively deep practice of prefabricated building based on the market environment has just started, the targeted research on energy conservation and emission reduction is not sufficient or even blank. Taking a project in Shenyang City of Liaoning Province as an example, this paper establishes the calculation formula of carbon emission of concrete prefabricated and cast-in-place residential buildings by using the emission factor method, calculates and compares the differences of carbon emission of the two kinds of buildings in the production stage, transportation stage and construction stage, and puts forward the corresponding carbon reduction measures of prefabricated buildings in each stage, so as to provide a powerful reference for the healthy and rapid development of other low-carbon buildings in China theoretical basis and practical guidance of the project.
Precedents and Chinese Judges: An Experiment
Authors: Liu John Zhuang , Klöhn Lars , Spamann Holger 
Published: July 2021

Abstract
We experimentally study the decision-making process of judges in China, where judges are specifically prohibited from citing prior decisions as the basis for their judgments, and where, in past surveys, most judges explicitly stated that precedent played at most a marginal role in their decisions. In an experiment resembling real-world judicial decision making, we find, however, that precedent seems to have a significant influence on the decisions of the participating Chinese judges. Indeed, judges spend more time reading prior cases than statutes, and they typically read precedents before they access the statutes. On the other hand, judges rarely mention the precedent in their reasons. Our findings suggest that the Chinese judiciary operates much more similarly to its homologues in the United States and elsewhere than their written opinions and much folklore would suggest.

Published: July 2021

AbstractJoint attention is important for children’s language development. We report two meta-analyses that demonstrate that the congruency in hearing status between parent and child affects the establishment and maintenance of joint attention. Dyads consisting of hearing parents and children with hearing loss, achieve fewer and briefer moments of joint attention in comparison to dyads of hearing parents and hearing children and dyads of deaf parents and deaf children. The theoretical and practical implications of these differences are discussed and placed in the context of two narrative syntheses. The first one focusing on parental strategies used to achieve and maintain moments of joint attention and the second one on the relation between joint attention and spoken language proficiency. We also expect that this review may serve as the start of quest towards a more detailed description (taxonomy) and operationalization of joint attention in the context of hearing loss.
Proteasome inhibitor-induced coronary vasospasm in multiple myeloma: a case report
Authors: Mikhail Philopatir , Rogers James , Forsyth Cecily , Ford Thomas J 
Published: July 2021

Abstract

Background
Coronary vasospasm is an increasingly recognized cause of myocardial infarction or myocardial ischaemia in patients without obstructive coronary artery disease. A thorough medication review may identify drugs or toxins that could trigger coronary vasospasm. This case provides mechanistic insight into the off-target effect of proteasome inhibition leading to coronary vasospasm in a patient referred with chest pain consistent with typical angina.

Case summary
A 72-year-old lady presented with anginal chest pain at rest with electrocardiogram evidence of myocardial ischaemia who was referred for invasive coronary angiography. This demonstrated minor coronary disease without an obstructive lesion. Vasoreactivity testing revealed diffuse coronary vasospasm of the left anterior descending artery. Carfilzomib was identified as the trigger for coronary vasospasm. Symptoms resolved without recurrence after appropriate treatment including cessation of the triggering agent.

Conclusion
Coronary spasm is a rare but important adverse reaction to proteasome inhibitors. This case supports the clinical utility of invasive coronary vasoreactivity testing in patients with ischaemia with no obstructive coronary artery disease.

Background
During the COVID-19 pandemic, the healthcare delivery systems have undergone significant alterations to prioritize access to care for patients affected by the novel coronavirus, while treatments and check-ups for chronic patients have often been postponed. Among chronic patients, people with a left ventricular assist device (LVAD) have been particularly affected by the COVID-19 pandemic since they require frequent medical check-ups to detect any initial complications. So far, no studies investigating the lived experiences of LVAD patients during the COVID-19 pandemic have been conducted.

Purpose
This study explored the lived experiences of people with an LVAD during the COVID-19 pandemic.

Methods
A qualitative analysis was conducted based on the interpretative phenomenological analysis (IPA) methodology. Eight men with an LVAD (median age 72.5, range 65-82 years) participated in audio-recorded, semi-structured, in-depth interviews exploring changes in their daily lives during the pandemic and how they responded to them. Journaling and triangulation were used to enhance the rigour of the study.

Results
Two main themes were extracted from the data: psychological distress and moving forward. Initially, LVAD patients experienced distress because they feared being infected and were worried that they could not receive adequate treatment in case of emergency due to changes in the healthcare delivery system. However, they employed different coping strategies (i.e. taking control of their health, keeping a positive attitude, seeking support) that allowed them to deal with this difficult situation and to move forward.

Conclusions
This study provides the first insights into the experiences of LVAD patients during the COVID-19 pandemic. Our findings could help clinicians identify LVAD patients’ needs and develop targeted interventions.

Background. Men remain at a higher risk of developing cardiovascular disease (CVD) than women and behavioral risk factor modification is an important preventive measure. However, engaging men in behavior change interventions is challenging. eHealth interventions have the potential to address this gap, though their effectiveness for reducing CVD risk in men is unclear.
Purpose. To conduct a systematic review and meta-analysis to evaluate the effectiveness of eHealth interventions for reducing CVD risk in men.
Methods. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and principles laid out by the Cochrane Handbook for Systematic Reviews of Interventions. A search of published randomised controlled trials (RCTs) with no date restrictions up to July 2020 was conducted across five electronic databases: Cochrane Central register of Controlled Trials (CENTRAL), Medline, CINAHL Plus, PsycINFO and SCOPUS. Reference lists of relevant systematic reviews and meta-analyses were manually searched for additional trials not identified during the database search. Eligible studies were RCTs that focused on the use of eHealth to improve a minimum of two major CVD related risk factors in males aged 18 years or older.
Results. A total of 3168 records were retrieved from the online database search, with nine trials meeting the inclusion criteria following screening and full-text assessment. Study quality ranged from low to unclear, with one trial at a high risk of bias. Compared to those in a control group or receiving printed materials, participants randomised to an eHealth intervention had statistically significant improvements in BMI (Z=-2.75, p = 0.01), body weight (Z=-3.25, p = 0.01), waist circumference (Z=-2.30, p = 0.02) and systolic (Z=-3.57, p = 0.01) and diastolic (Z=-3.56, p = 0.01) blood pressure. Though less evident, there were also improvements in physical activity and diet in favour of the intervention group.
Conclusion. This was the first systematic review and meta-analysis conducted on the effectiveness of eHealth interventions for reducing CVD risk in men. This review suggests that eHealth interventions can reduce CVD risk in adult men through behavior change. However, we were unable to determine the association between intervention characteristics and outcomes. Also, overall, participant adherence to the intervention was poor. Both of these issues should be considered in future studies.
The C-terminal region of yeast ubiquitin–protein ligase Not4 mediates its cellular localization and stress response

Published: July 2021

ABSTRACT
Transient modification of the environment involves the expression of specific genes and degradation of mRNAs and proteins. How these events are linked is poorly understood. CCR4-NOT is an evolutionary conserved complex involved in transcription initiation and mRNA degradation. In this paper, we report that the yeast Not4 localizes in cytoplasmic foci after cellular stress. We focused our attention on the functional characterization of the C-terminus of the Not4 protein. Molecular dissection of this region indicates that the removal of the last 120 amino acids, does not affect protein localization and function, in that the protein is still able to suppress the thermosensitivity observed in the not4Δ mutant. In addition, such shortened form of Not4, as well its absence, increases the transcription of stress-responsive genes conferring to the cell high resistance to the oxidative stress. On the contrary, the last C-terminal 211 amino acids are required for proper Not4 localization at cytoplasmic foci after stress. This truncated version of Not4 fails to increase the transcription of the stress genes, is more stable and seems to be toxic to cells undergoing oxidative stress.
Transcriptomic markers of fungal growth, respiration and carbon-use efficiency

Published: July 2021

ABSTRACT
Fungal metabolic carbon acquisition and its subsequent partitioning between biomass production and respiration, i.e. the carbon-use efficiency (CUE), are central parameters in biogeochemical modeling. However, current available techniques for estimating these parameters are all associated with practical and theoretical shortcomings, making assessments unreliable. Gene expression analyses hold the prospect of phenotype prediction by indirect means, providing new opportunities to obtain information about metabolic priorities. We cultured four different fungal isolates (Chalara longipes, Laccaria bicolor, Serpula lacrymans and Trichoderma harzianum) in liquid media with contrasting nitrogen availability and measured growth rates and respiration to calculate CUE. By relating gene expression markers to measured carbon fluxes, we identified genes coding for 1,3-β-glucan synthase and 2-oxoglutarate dehydrogenase as suitable markers for growth and respiration, respectively, capturing both intraspecific variation as well as within-strain variation dependent on growth medium. A transcript index based on these markers correlated significantly with differences in CUE between the fungal isolates. Our study paves the way for the use of these markers to assess differences in growth, respiration and CUE in natural fungal communities, using metatranscriptomic or the RT-qPCR approach.
RiceTSV2encoding threonyl-tRNA synthetase is needed for early chloroplast development and seedling growth under cold stress

Published: July 2021

AbstractThreonyl-tRNA synthetase (ThrRS), one of the aminoacyl-tRNA synthetases (AARSs), plays a crucial role in protein synthesis. However, the AARS functions on rice chloroplast development and growth were not fully appraised. In this study, a thermo-sensitive virescent mutant tsv2, which showed albino phenotype and lethal after the 4-leaf stage at 20°C but recovered to normal when the temperatures rose, was identified and characterized. Map-based cloning and complementation tests showed that TSV2 encoded a chloroplast-located ThrRS protein in rice. The Lys-to-Arg mutation in the anticodon-binding domain hampered chloroplast development under cold stress, while the loss of function of the ThrRS core domain in TSV2 fatally led to seedling death regardless of growing temperatures. In addition, TSV2 had a specific expression in early leaves. Its disruption obviously resulted in the downregulation of certain genes associated with chlorophyll biosynthesis, photosynthesis, and chloroplast development at cold conditions. Our observations revealed that rice nuclear-encoded TSV2 plays an important role in chloroplast development at the early leaf stage under cold stress.
