Stray Light Correction Algorithm for High Performance Optical Instruments: The Case of Metop-3MI

Stray light is a critical aspect for high performance optical instruments. When stray light control by design is insufficient to reach the performance requirement, correction by post-processing must be considered. This situation is encountered for example in the case of the Earth observation in-strument 3MI, whose stray light properties are complex due to the presence of many ghosts dis-tributed on the detector array. We implement an iterative correction method and discuss its con-vergence properties. Spatial and field binning can be employed to reduce the computation time but at the cost of a decreased performance. Interpolation of the stray light properties is required to achieve high performance correction. For that, two methods are proposed and tested. The first interpolate the stray light in the field domain while the second applies a scaling operation based on a local symmetry assumption. Ultimately, the scaling method is selected and a stray light reduction by a factor of 58 is obtained at 2σ (129 at 1σ) for an extended scene illumination.
H∞ model following control of linear parameter‐varying descriptor systems

The topic of H∞ model following control of linear parameter‐varying (LPV) descriptor systems is considered in this article. The main objective of using the H∞ model following control system is to ensure that the outputs of the LPV descriptor system track robustly the reference model outputs in the presence of bounded energy disturbances. The H∞ model following control system consists of three subsystems: an LPV feedforward controller, an LPV reference model, and an LPV H∞ descriptor dynamic output‐feedback controller. The design matrices of these three subsystems are obtained by solving a set of tractable LPV matrix equations and inequalities. Two descriptor systems: an electrical circuit and a DC motor with an unbalanced disc are modeled as LPV descriptor systems and then used to show the design steps. The simulation results show the effectiveness of the proposed H∞ model following control system.

Analgesic effect of photobiomodulation after placement of elastomeric separators: randomized controlled clinical trial

Objective: Pain resulting from the positioning of elastomeric separators is a strong reason for abandoning orthodontic treatment. So, this study aims to verify the analgesic effects of photobiomodulation (PBM) in participants submitted to orthodontics with elastomeric separators. Methods: Participants were individuals who received separators on the mesial and distal surfaces of the first molars. They were randomly separated into two groups: an experimental group that received photobiomodulation (PBM) (n=22) and a placebo group (n=22). After the positioning of the separators, the PBM group received one application of PBM (2 J of energy applied in 20 seconds per point, adding up to 12 J per molar (6 J on the vestibular surface and 6 J on the lingual surface) over the cervical portion and the apical third of the tooth. Pain was measured one hour after placement, with the aid of a visual analog scale (VAS). Statistical analysis involved the Mann-Whitney, Fisher’s Exact and chi-square tests. Results: Reports of severe pain only occurred in the placebo group. However, a larger percentage of the individuals in the PBM group reported feeling moderate pain compared to this same intensity in the placebo group. No significant differences among groups were found with regards to reports of mild pain and no pain. An association was found between pain and the female sex in both groups. Conclusion: Significant difference was found in severe pain sensitivity when PBM was applied after the positioning of elastomeric separators, favoring the irradiated participants. Thus, PBM may be a useful tool in orthodontic treatment. Clinical Trials Reference Number (www.ClinicalTrials.gov), NCT03939988.
Pimarane Diterpenoids from Aerial Parts of Lycopus lucidus and Their Antimicrobial Activity

The ethyl acetate fraction obtained from aerial parts of L. lucidus was subjected for isolation of new bioactive compounds, which enabled isolation of five new pimarane-type diterpenoids, namely, 3β, 8β, 12β, 18-tetrahydroxy pimar-15-ene (10), 7α, 8β, 12β, 18-tetrahydroxy pimar-15-ene (11), 3β, 8β, 11β, 12α, 18-pentahydroxy pimar-15-ene (12), 12β acetoxy, 8β, 3β, 18-trihydroxy pimar-15-ene (13), and 3β acetoxy, 8β, 12β, 18-trihydroxy pimar-15-ene (14), along with nine known compounds. The structures were elucidated by spectroscopic analysis and comparison with literature data. The isolated new pimarane diterpenoids were examined for antimicrobial activity against Gram-negative and Gram-positive bacteria strains. Among them, the compound 3β, 8β, 12β, 18-tetrahydroxy pimar-15-ene (10) was most effective, exhibiting minimum inhibitory concentration (MIC) values of 15.62 µg/mL against Staphylococcus epidermidis, 31.25 µg/mL against Staphylococcus aureus, 62.5 µg/mL against Pseudomonas aeruginosa, and 125 µg/mL against Escherichia coli.
Identifying key trains and their reasonable ratios in high-speed rail timetables

ABSTRACT A key train plays an important role in the rail timetable. The unreasonable key trains' layout greatly influences the normal train-running order, thus affecting the quality of the high-speed rail (HSR) timetable. This article studies the probability produced by train paths for overcoming bottlenecks and identifies key trains in the HSR timetable by means of predicting the conflicts using triangular fuzzy numbered workflow nets, that is, key trains have greater effect on other trains and need to pay close attention to them. In addition, stimulations results that were performed with the HSR dispatching system illustrate the conclusion. Moreover, under certain capacity requirements, this article calculates reasonable key trains' ratio for different combinations of speed in a HSR timetable. This research demonstrates that (1) low-speed (Class B) trains are key trains in the HSR timetable and (2) when trains of 350 km/h and 250 km/h run on the same line, the key trains (250 km/h) ratio of the Beijing-Shanghai HSR should be less than 10%. Currently, for trains running on the Beijing-Shanghai HSR, whose speeds are 300 km/h and 250 km/h, the key trains (250 km/h) ratio should be no more than 20%.
Effect of a Rehabilitation Program on the Quality of Life of Patients with Lower Limb Amputation

Lower limb amputation (LLA) is usually performed as a life saving procedure to remove all infected, pathologic, or ischemic tissue. Irrespective of the cause of LLA, it has a significant and dramatic change in a person’s life which has an effect on quality of life of patients due to the physical activity limitations immediately after amputation and long-term implications in different aspects of life. Objective: Determine the effect of a rehabilitation program on the quality of life for patients with lower limb amputation. Setting: This study was conducted in Surgical Units and Vascular Unit, Department of Surgery, Alexandria Main University and Alexandria Vascular Center (AVC). Subjects: The study subjects were included 50 adult patients with unilateral major LLA, able to communicate effectively and agreed to participate in the study. Tools: Two tools were used for data collection: Preoperative and Postoperative Lower Limb Amputation Assessment Tool and Short Form 36 (SF-36) Health Survey Questionnaire. Results: The study showed that patients in the study group who received the rehabilitation program had higher scores of SF36 health domains than those in the control group who received routine hospital care. In addition, there was a statistical significant difference between the two groups in relation to overall quality of life. Conclusion: It can be concluded that mean scores of SF36 health domains improved significantly in the study group compared to control group after applying the rehabilitation program. Recommendations: The rehabilitation program should be considered as an integral part in the hospital routine care of patients with LLA.
Relationship among Materialism, Attitudes Regarding Money, Peer Influence and Satisfaction with Life in Chilean Adolescents

Materialism has been recognized as an important variable in postmodern societies; however, most of the studies on this concept have focused on the adult population. The aim of the present study is to determine the possible association between materialism and life satisfaction, and the possible mediating role of attitudes towards money and peer influence in this association, in a sample of Chilean adolescents. A sample of 1325 Chilean secondary school students completed a questionnaire measuring materialism, attitudes in regards with money, susceptibility to peer influence, and satisfaction with life. First, a confirmatory factor analysis was conducted to validate the scalers. Secondly, a theoretical model was tested using Hayes (2013) SPSS macro, PROCESS. The theoretical model included materialism as the predictor variable, satisfaction with life as the predicted variable, and attitudes towards money and susceptibility to peer influence as mediator variables. Results indicate that materialistic attitudes regarding money strengthens a negative relation between materialism and satisfaction with life. This tendency is not observed in susceptibility to peer influence despite being positively associated with materialism and attitudes regarding money. These findings suggest that the variables materialism and attitudes regarding money play a relevant role in the life satisfaction of Chilean adolescents.
How Cells Deal with the Fluctuating Environment: Autophagy Regulation under Stress in Yeast and Mammalian Systems

Eukaryotic cells frequently experience fluctuations of the external and internal environments, such as changes in nutrient, energy and oxygen sources, and protein folding status, which, after reaching a particular threshold, become a type of stress. Cells develop several ways to deal with these various types of stress to maintain homeostasis and survival. Among the cellular survival mechanisms, autophagy is one of the most critical ways to mediate metabolic adaptation and clearance of damaged organelles. Autophagy is maintained at a basal level under normal growing conditions and gets stimulated by stress through different but connected mechanisms. In this review, we summarize the advances in understanding the autophagy regulation mechanisms under multiple types of stress including nutrient, energy, oxidative, and ER stress in both yeast and mammalian systems.

PERFORMANCE OF SOME EGYPTIAN CLOVER CULTIVARS AND THEIR TOLERANCE TO DODDER INFESTATION

Dodder parasite (Cuscuta planiflora. L) is the main obstacle which causes drastic yield losses in Egyptian forage clover crop in Egypt, accompanied with seed contamination by dodder seeds due to their similarity in size and shape to clover seeds. The present study aimed to determine the magnitude of yield losses due to dodder infestation and to estimate the degree of tolerance of some important Egyptian clover cultivars to dodder infection. Five forage clover cultivars, namely Gemmeza 1, Giza 6, Sakha 4, Helaly and Serw were tested to determine the magnitude of yield losses in these cultivars to dodder infestation and their degree of dodder tolerance under five dodder artificial infestation rates, 0, 0.01, 0.02, 0.03 and 0.04 g/pot of dodder seeds carried out in two pot experiments during 2015/2016 and 2016/ 2017 winter seasons in complete randomized block design. Under dodder infestation rates at 0.01, 0.02, 0.03 and 0.04 g/pot the dry forage yield of clover losses were estimated by 32.6,37.9,47.8 and 54.4%, respectively, in 2016 season, and 31.8,46.6,54.6 and 63.7%,, respectively, in 2017 season as compared with the yield of clover free from dodder infestation. The effect of interaction between clover cultivars X dodder seeding infestation rate (g/pot) show that studied cultivars namely Gemmeza 1, Giza 6, Helaly, and Sakha 4 had the lowest infestation rates under 0.01-0.02g/pot of dodder seeds accompanied with increases in fresh and dry weight forage /pot, stem weight and stem length and high tolerance index (70-73%) with Sakha 4compared to El Serw 1 cultivar with the lowest tolerance index (26.1-32.9%), and can be classified as susceptible cultivar to dodder infestation. Such results suggest that breeders can select highest tolerant cultivars of clover under artificial infestation rates accompanied with decrease in dodder infestation %.
Characterization of the Complete Chloroplast Genome of the Dragonhead Herb, Dracocephalum heterophyllum (Lamiaceae), and Comparative Analyses with Related Species

Dracocephalum heterophyllum (Lamiaceae: tribe Mentheae) is an annual aromatic herb native to East Asia with a long record of human uses, including medicinal, alimentary, and ornamental values. However, no information is available about its molecular biology, and no genomic study has been performed on D. heterophyllum. Here, we report the complete chloroplast (cp) genome of D. heterophyllum and a series of comparative genomic analyses between this and closely related species of Lamiaceae. Results indicated that the cp genome has a typical circular structure of 150,869 bp in length, consisting of a long single-copy (LSC) region with 82,410 bp, a short single-copy (SSC) region with 17,098 bp, and two inverted repeat (IR) regions of 51,350 bp. A total of 133 genes were identified, including 37 tRNA genes, 8 rRNA genes and 88 protein-coding genes, with a GC content of 37.8%. The gene content, organization, and GC values observed here were similar to those of other Dracocephalum species. We detected 99 different simple sequence repeat loci, and the codon usage analysis revealed a preferential use of the Leu codon with an A/U ending. Comparative analysis of cp genome sequences revealed five highly variable regions with remarkably higher Pi values (>0.03). The mean Ka/Ks between D. heterophyllum and three other Dracocephalum species ranged from 0.01079 (psbB) to 1.0497 (ycf2). Two cp genes, ycf2 and rps11, were proven to have high ratios of Ka/Ks, implying that cp genes may had undergone positive selection in the evolutionary history. We performed multiple sequence alignments using the cp genome of 22 species and constructed maximum likelihood (ML) and Bayesian trees, and found that D. heterophyllum were more closely related to D. moldavica and D. palmatum. In addition, the phylogenetic relationships between Dracocephalum and other members of Lamiaceae were consistent with previous results. These results are valuable for further formulating effective strategies of conservation and management for species in Dracocephalum, as well as providing a foundation for future research on the genetic resources of Dracocephalum.
Working From Home and Corporate Real Estate

We examine how corporate real estate market participants adjust to the anticipated take-off of teleworking. We develop an indicator of the exposure of counties to teleworking in France by combining teleworking capacity with incentives and frictions to its deployment. We study how this indicator relates to prices and quantities in the corporate real estate market. We find that for offices in counties more exposed, the Covid-19 crisis has led to(1) higher vacancy rates, (2) less construction, (3) lower prices. Our findings reveal that teleworking has already an impact on the office market. Furthermore, forward-looking indicators suggest that market participants are anticipating a deeper shift to teleworking in the coming years.
Nocturnal dexmedetomidine for prevention of delirium in critically ill surgical patients: a randomized control trial protocol

Background: Nocturnal or postoperative dexmedetomidine has been shown to reduce the incidence of delirium in critically ill surgical patients without an increase in any complications. However, it is not clear whether dexmedetomidine has preventive effect against delirium in the patients with high risk of postoperative delirium (POD) since no previous studies have clearly emphasized high-risk surgical patients. Method: In this single-center, double-blind, randomized controlled trial, we randomize 114 high risk POD patients defined by developed predictive scores and admitted to surgical intensive care units (SICUs) into 2 groups: nocturnal dexmedetomidine (9 pm – 6 am) and placebo. The outcomes were incidence of POD, delirium-free days, secondary delirium-related complications and concerned complications including hypotension and bradycardia. Other treatments apart from intervention are standardized. Intention to treat analysis is used to analyze all data. Hypothesis: We hypothesize that nocturnal dexmedetomidine giving to high-risk POD patients admitted to SICUs postoperatively would (1) reduce incidence of POD (2) improve delirium-free days (3) reduce secondary delirium-related complications (4) show no difference in hypotension and bradycardia between groups. Ethics and dissemination: The trial receives ethic approval from Siriraj Institutional Review Board. We plan to disseminate the results in peer-reviewed critical care medicine or anesthesiology-related journals, conferences nationally and internationally. Trial registration: TCTR20210217001

Lessons and Recommendations from a Pentobarbital Shortage: US and Canada 2021

Simple Summary Pentobarbital sodium is a common animal euthanasia drug in the United States and Canada, as well as in other countries with access to it. A shortage of the drug in 2021 created a dilemma for those needing to perform the euthanasia procedure in animals facing negative welfare conditions. The reason for the shortage was attributed to chemical production issues. The veterinary community worked together to conserve what euthanasia drug was available, and to identify alternative methods that could be quickly implemented, while still adhering to safety and efficacy requirements. Through collaborative efforts, useful guidelines were created and shared with a variety of animal industries to ensure euthanasia procedures could still be facilitated when necessary. While pentobarbital sodium has increased in availability in 2022, lessons have been learned to support animal care should the shortage occur again. Abstract In 2021, a shortage in the supply of the euthanasia drug pentobarbital sodium affected animal care professionals around the world, including in the United States and Canada. Pentobarbital sodium is the drug of choice for companion animal euthanasia in both countries. The decreased availability of pentobarbital sodium affected a number of animal care industries, forcing conservation of the drug and the use of alternative methods and other agents to facilitate humane death for all manner of animal species. Veterinary medical groups, laboratory research institutions, and the animal sheltering industry worked together to identify the best path forward to maintain routine euthanasia practices and to protect the welfare of animals. This article aims to explore the reasons behind the shortage and to highlight the necessary responses and adjustments made in order to continue providing euthanasia services in North America. Recommendations for handling future pentobarbital shortages are included.
Effects of bacitracin zinc, potassium diformate and lauric acid on duodenal digestive functions, intestinal morphology and caecal microflora of broilers

This study investigated the effects of bacitracin zinc, potassium diformate and lauric acid on duodenal digestive functions, intestinal morphology and caecal microflora of broilers. A total of 240 male broilers were randomly allotted to four treatments consisting of five replicates with 12 birds per replicate. The dietary treatments were CON group (basal diet), ANT group (basal diet + 40 mg/kg bacitracin zinc), KDF group (basal diet + 1 000 mg/kg potassium diformate), and LA group (basal diet + 500 mg/kg lauric acid). The results showed that the chymotrypsin activity was significantly enhanced on days 21 and 42 in KDF group compared with CON group (P < 0.05), but there were no effects on the activities of trypsin and amylase (P > 0.05). No differences in digestive enzyme activities were found between ANT and LA groups (P > 0.05). Compared with CON group, the villus length and the villus-to-crypt ratio were significantly increased on days 21 and 42, and the crypt depth was significantly decreased in ANT, KDF and LA groups (P < 0.05). Compared with CON group, the supplementation of LA increased the relative abundance of Faecalibacterium on day 21 and the relative abundance of Bacillus on day 42 in caecum, while the supplementation of KDF increased the relative abundance of Faecalibacterium and decreased the relative abundance of Dorea on day 42 in caecum (P < 0.05). In conclusion, the supplementation of KDF enhanced the chymotrypsin activity. Dietary KDF and LA maintained the intestinal morphology by improving the villus length and the villus-to-crypt ratio and decreasing the crypt depth, and regulated the caecal microflora.
