A unified calibration method of 3D laser profile measurement with different of laser-line lengths
Authors: Wu Xiaojun , Liu Bo , Li Peng , Liu Yunhui 
Published: March 2023

Purpose
Existing calibration methods mainly focus on the camera laser-plane calibration of a single laser-line length, which is not convenient and cannot guarantee the consistency of the results when several three-dimensional (3D) scanners are involved. Thus, this study aims to provide a unified step for different laser-line length calibration requirements for laser profile measurement (LPM) systems.

Design/methodology/approach
3D LPM is the process of converting physical objects into 3D digital models, wherein camera laser-plane calibration is critical for ensuring system precision. However, conventional calibration methods for 3D LPM typically use a calibration target to calibrate the system for a single laser-line length, which needs multiple calibration patterns and makes the procedure complicated. In this paper, a unified calibration method was proposed to automatically calibrate the camera laser-plane parameters for the LPM systems with different laser-line lengths. The authors designed an elaborate planar calibration target with different-sized rings that mounted on a motorized linear platform to calculate the laser-plane parameters of the LPM systems. Then, the camera coordinates of the control points are obtained using the intersection line between the laser line and the planar target. With a new proposed error correction model, the errors caused by hardware assembly can be corrected. To validate the proposed method, three LPM devices with different laser-line lengths are used to verify the proposed system. Experimental results show that the proposed method can calibrate the LPM systems with different laser-line lengths conveniently with standard steps.

Findings
The repeatability and accuracy of the proposed calibration prototypes were evaluated with high-precision workpieces. The experiments have shown that the proposed method is highly adaptive and can automatically calibrate the LPM system with different laser-line lengths with high accuracy.

Research limitations/implications
In the repeatability experiments, there were errors in the measured heights of the test workpieces, and this is because the laser emitter had the best working distance and laser-line length.

Practical implications
By using this proposed method and device, the calibration of the 3D scanning laser device can be done in an automatic way.

Social implications
The calibration efficiency of a laser camera device is increased.

Originality/value
The authors proposed a unified calibration method for LPM systems with different laser-line lengths that consist of a motorized linear joint and a calibration target with elaborately designed ring patterns; the authors realized the automatic parameter calibration.
A rapid method for measuring ATP + ADP + AMP in marine sediment
Authors: Orsi William D. 
Published: March 2023

AbstractIn this report, I describe a method for rapid measurement of total adenylate (ATP + ADP + AMP) in marine sediment samples for estimating microbial biomass. A simple ‘boil and dilute’ method is described here, whereby adding boiled MilliQ water to sediments increases the detection limit for ATP + ADP + AMP up to 100‐fold. The lowered detection limit of this method enabled the detection ATP + ADP + AMP in relatively low‐biomass sub‐seafloor sediment cores with 104 16S rRNA gene copies per gram. Concentrations of ATP + ADP + AMP correlated with 16S rRNA gene concentrations from bacteria and archaea across six different sites that range in water depth from 1 to 6000 m indicating that the ATP + ADP + AMP method can be used as an additional biomass proxy. In deep sea microbial communities, the ratio of ATP + ADP + AMP concentrations to 16S rRNA genes >1 m below seafloor was significantly lower compared to communities in the upper 30 cm of sediment, which may be due to reduced cell sizes and or lower ATP + ADP + AMP concentrations per cell in the deep sea sub‐seafloor biosphere. The boil and dilute method for ATP + ADP + AMP is demonstrated here to have a detection limit sufficient for measuring low biomass communities from deep sea sub‐seafloor cores. The method can be applied to frozen samples, enabling measurements of ATP + ADP + AMP from frozen sediment cores stored in core repositories from past and future international drilling campaigns.
Analysis of tax effort in WAEMU: How important are institutional/administrative reforms?
Authors: Diabaté Nahoussé , Koffi Mounoufié V. 
Published: March 2023

AbstractThis paper examines, in depth, the hypotheses explaining the tax effort of seven West African Economic and Monetary Union (WAEMU) countries over the period 1996–2018. The studies of Karakaplan and Kutlu were applied to the stochastic tax frontier model. This provides a new method for analyzing tax effort that solves potential endogeneity problems, especially those of income. This study confirms the positive impact of income, trade openness, urbanization, government capital spending and anticorruption on tax revenue mobilization, while the size of the agricultural sector has a negative impact on tax revenue. On the other hand, reforms of tax institutions have no effect on tax effort. The average tax revenue of the countries of the WAEMU is 11.34 and the average tax effort is estimated at 0.7901 over the period 1996–2018. Thus, these countries could achieve a tax revenue to GDP ratio of 13.72% if they fully exploit their potential.

AbstractChicken plumage colouration is an important trait related to productivity in poultry industry. Therefore, the genetic basis for pigmentation in chicken plumage is an area of great interest. However, the colour trait is generally regarded as a qualitative trait and representing colour variations is difficult. In this study, we developed a method to quantify and classify colour using an F2 population crossed from two pure lines: White Leghorn and the Korean indigenous breed Yeonsan Ogye. Using red, green, and blue values in the cropped body region, we identified significant genomic regions on chromosomes 33:3 160 480–7 447 197 and Z:78 748 287–79 173 793. Furthermore, we identified two potential candidate genes (PMEL and MTAP) that might have significant effects on melanin‐based plumage pigmentation. Our study presents a new phenotyping method using a computer vision approach and provides new insights into the genetic basis of melanin‐based feather colouration in chickens.

AbstractBackgroundConsolidation durvalumab after concurrent chemoradiation is the standard of care for unresectable stage III non‐small cell lung cancer (NSCLC) based on the PACIFIC trial. However, there have been reports in the literature suggesting the efficacy of the treatment differs in patients whose tumors harbor epidermal growth factor receptor (EGFR) mutations and in those with low programed death ligand‐1 (PD‐L1) expression. This study describes the survival outcomes for patients with unresectable stage III NSCLC treated with chemoradiation followed by durvalumab with a specific focus on EGFR mutation status and PD‐L1 expression.MethodsThis retrospective observational study was conducted across six sites in Greater Sydney, Australia. It included all patients diagnosed with unresectable stage III NSCLC treated with chemoradiation and who received at least one cycle of durvalumab between January 2018 and September 2021. Patients were stratified according to EGFR mutation status and PD‐L1 tumor proportion score (TPS) of 1%.ResultsOf the 145 patients included in the analysis, 15/145 (10%) patients harbored an EGFR mutation and 61/145 (42%) patients had PD‐L1 TPS of <1%. At a median follow‐up of 15.1 months from the start of durvalumab, median progression‐free survival (PFS) in EGFR mutant versus wild‐type patients was 7.5 and 33.9 months, respectively (hazard ratio [HR]: 2.7; 95% confidence intervals [95% CI] 1.2–5.7; p = .01). Overall survival (OS) was not different between EGFR mutant and wild‐type patients. There was no statistically significant difference in PFS (HR .7, 95% CI .4–1.7, p = .43) or OS (HR .5, 95% CI .4–4.7, p = .16) between patients with PD‐L1 TPS of <1% versus PD‐L1 TPS of ≥1%.ConclusionsOur data adds to the growing evidence that suggests consolidation durvalumab after definitive chemoradiation may not be as efficacious in patients with EGFR‐mutant tumors compared with EGFR wild‐type NSCLC.

Published: March 2023

AbstractBackgroundThe Breast Surgeons of Australia and New Zealand (BreastSurgANZ) Quality Audit (BQA) of Breast Cancer Care is a prospective population‐based database designed for annual audit of compliance with internally derived Quality Indicators (QI)s. While there is no international consensus for QIs, audit against an external international benchmark is possible through use of QIs defined by the 2017 European Society of Breast Cancer Specialists (EUSOMA) Guidelines.MethodsBQA data from 29,088 female patients between 1/1/2018 and 31/12/2019 were stratified by the EUSOMA definition of low‐volume hospitals (LVH <150 patients p.a.) and high‐volume hospitals (HVH ≥150 patients p.a.), and percentage compliance (±95% CI) with 14 mandatory EUSOMA QI sub‐parts were determined.ResultsANZ LVH met the quality threshold for 10, and HVH for 8 EUSOMA QI that assessed MDT, surgical approach, adjuvant radiotherapy in the LVH setting, avoidance of overtreatment, and use of endocrine therapy. ANZ did not meet the quality thresholds for QIs assessing use of neoadjuvant chemotherapy, and adjuvant radiotherapy in the HVH setting.ConclusionBreast cancer care in ANZ is comparable with an international standard. ANZ surgeons performed at a high standard in discussion of breast cancer patients by MDT, and appropriate use of adjuvant radiotherapy by LVH. Improvements can be made in completeness of data capture, and inclusion of genetic syndrome and Ki67% in data collection. Due to the rapid evolution of breast cancer treatments, there is need for contemporary update of QI relating to the use of neoadjuvant systemic therapies.
Testing the Social Function of Metacognition for Common‐Pool Resource Use
Authors: Fischer Helen , Wijermans Nanda , Schlüter Maja 
Published: March 2023

AbstractMetacognition, the ability to monitor and evaluate our own cognitive processes, confers advantages to individuals and their own judgment. A more recent hypothesis, however, states that explicit metacognition may also enhance the collective judgment of groups, and may enhance human collaboration and coordination. Here, we investigate this social function hypothesis of metacognition with arguably one of the oldest collaboration problems humans face, common‐pool resource use. Using an agent‐based model that simulates repeated group interactions and the forming of collective judgments about resource extraction, we show that (1) in “kind” environments (where confidence and judgment accuracy correlate positively), explicit metacognition may allow groups to reach more accurate judgments compared to groups exchanging object‐level information only; while (2) in “wicked” environments (where confidence and judgment accuracy correlate negatively), explicit metacognition may protect groups from the large judgment errors yielded by groups using metacognitive information for individual‐level learning only (implicit metacognition). With explicit metacognition, this research highlights a novel mechanism which, among others, provides a testable explanation of the often‐observed finding that groups all over the world communicate to enhance common property use.

AbstractBackgroundIncreasing access and better allocation of organs in the field of transplantation is a critical problem in clinical care. Limitations exist in accurately predicting allograft discard. Potential exists for machine learning to provide a balanced assessment of the potential for an organ to be used in a transplantation procedure.MethodsWe accessed and utilized all available deceased donor United Network for Organ Sharing data from 1987 to 2020. With these data, we evaluated the performance of multiple machine learning methods for predicting organ use. The machine learning methods trialed included XGBoost, random forest, Naïve Bayes (NB), logistic regression, and fully connected feedforward neural network classifier methods. The top two methods, XGBoost and random forest, were fully developed using 10‐fold cross‐validation and Bayesian optimization of hyperparameters.ResultsThe top performing model at predicting liver organ use was an XGBoost model which achieved an AUC‐ROC of .925, an AUC‐PR of .868, and an F1 statistic of .756. The top performing model for predicting kidney organ use classification was an XGBoost model which achieved an AUC‐ROC of .952, and AUC‐PR of .883, and an F1 statistic of .786.ConclusionsThe XGBoost method demonstrated a significant improvement in predicting donor allograft discard for both kidney and livers in solid organ transplantation procedures. Machine learning methods are well suited to be incorporated into the clinical workflow; they can provide robust quantitative predictions and meaningful data insights for clinician consideration and transplantation decision‐making.

AbstractSperm motility‐initiating substance (SMIS) is an oviductal protein critical for internal fertilization in urodeles. It contributes to the establishment of various reproductive modes in amphibians and is thus a unique research model for the gene evolution of gamete‐recognizing ligands that have diversified among animal species. In this study, a paralogous SMIS gene, smis2, was identified via the RNA sequencing of the oviduct of the newt, Cynops pyrrhogaster. The base sequence of the smis2 gene was homologous (˃90%) to that of the original smis gene (smis1), and deduced amino acid sequences of both genes conserved six cysteine residues essential for the cysteine knot motif. Furthermore, smis2 complementary DNA was identified in the oviduct of Cynops ensicauda, and the base substitution patterns also suggested that the smis gene was duplicated in the Salamandridae. Nonsynonymous/synonymous substitution ratios of smis1 and smis2 genes were 0.79 and 2.6, respectively, suggesting that smis2 gene evolution was independently driven by positive selection. Amino acid substitutions were concentrated in the cysteine knot motif of SMIS2. The smis2 gene was expressed in some organs in addition to the oviduct; in contrast, SMIS1 was only expressed in the oviduct. The SMIS2 protein was suggested to be produced and secreted at least in the oviduct and redundantly act in sperm. These results suggest that smis1 plays the original role in the oviduct, whereas smis2 may undergo neofunctionalization, which rarely occurs in gene evolution.

Published: March 2023

AbstractSARS‐CoV‐2 infection could disrupt the endocrine system directly or indirectly, which could result in endocrine dysfunction and glycaemic dysregulation, triggering transient or persistent diabetes mellitus. The literature on the complex relationship between COVID‐19 and endocrine dysfunctions is still evolving and remains incompletely understood. Thus, we conducted a review on all literature to date involving COVID‐19 associated ketosis or diabetic ketoacidosis (DKA). In total, 27 publications were included and analysed quantitatively and qualitatively. Studies included patients with DKA with existing or new onset diabetes. While the number of case and cohort studies was limited, DKA in the setting of COVID‐19 seemed to increase risk of death, particularly in patients with new onset diabetes. Future studies with more specific variables and larger sample sizes are needed to draw better conclusions.

Published: March 2023

AbstractBackground/AimThe extent of education regarding dental trauma within dental schools around the world is believed to be very diverse, but also largely unknown. The aim of this study was to analyze and depict the current curriculum regarding dental trauma education among all Canadian dental schools, in an effort to refine and consolidate the education system.MethodsA survey was conducted over a scheduled meeting with dental trauma Instructors from all 10 dental schools in Canada. Questions were categorized into three sections investigating the dental trauma curriculum, the examinations/assessments of students, and the clinical exposure provided to students during the course of their dental studies. Data were first analyzed individually, and then common findings were grouped together.ResultsA total of 17 instructors were interviewed. In 9 out of the 10 universities, dental trauma education remains fragmented with an overall mean of only 4 ± 5.2 h allocated to teaching dental trauma throughout the dental courses. Only one single university reported testing students following the completion of their dental trauma course, and only one university conducted a final examination dedicated separately to dental trauma only. All instructors reported a lack of ample exposure to trauma cases during clinical rotations.ConclusionsMany deficiencies exist in teaching dental trauma among Canadian universities. Due to low clinical exposure, students might be under‐prepared to clinically manage trauma cases. Also, the lack of unification in the curriculum creates confusion among students. Additional clinical exposure along with unification within, and between, dental schools could result in a more coherent and a better presented dental trauma curriculum.
Changing patterns of nest predation and predator communities along a tropical elevation gradient

Published: March 2023

AbstractTropical montane communities host the world's highest beta diversity of birds, a phenomenon usually attributed to community turnover caused by changes in biotic and abiotic factors along elevation gradients. Yet, empirical data on most biotic factors are lacking. Nest predation is thought to be especially important because it appears to be common and can change selective pressures underlying life history traits, which can alter competitive interactions. We monitored 2538 nests, 338 of which had known nest predators, to evaluate if nest predation changes along a tropical elevational gradient. We found that nest predation decreased with elevation, reflecting the loss of lowland predators that do not tolerate colder climates. We found different “super” nest predators at each elevation that accounted for a high percentage of events, suggesting that selection pressures exerted by nest predator communities may be less diffuse than has been hypothesized, at least for birds nesting in the understory.

AbstractBackground and purposeElevated plasma concentrations of neural cell adhesion molecule 1 (NCAM1) and p75 neurotrophin receptor (p75) in patients with peripheral neuropathy have been reported. This study aimed to determine the specificity of plasma concentration elevation of either NCAM1 or p75 in a subtype of Charcot–Marie–Tooth disease (CMT) and its correlation with pathologic nerve status and disease severity.MethodsBlood samples were collected from 138 patients with inherited peripheral neuropathy and 51 healthy controls. Disease severity was measured using Charcot–Marie–Tooth Neuropathy Score version 2 (CMTNSv2), and plasma concentrations of NCAM1 and p75 were analyzed by enzyme‐linked immunosorbent assay. Eight sural nerves from CMT patients were examined to determine the relation of histopathology and plasma NCAM1 levels.ResultsPlasma concentration of NCAM1, but not p75, was specifically increased in demyelinating subtypes of CMT (median = 7100 pg/mL, p < 0.001), including CMT1A, but not in axonal subtype (5964 pg/mL, p > 0.05), compared to the control (3859 pg/mL). CMT1A patients with mild or moderate severity (CMTNSv2 < 20) showed higher levels of plasma NCAM1 than healthy controls. Immunofluorescent NCAM1 staining for the sural nerves of CMT patients showed that NCAM1‐positive onion bulb cells and possible demyelinating Schwann cells might be associated with the specific increase of plasma NCAM1 in demyelinating CMT.ConclusionsThe plasma NCAM1 levels in demyelinating CMT might be a surrogate biomarker reflecting pathological Schwann cell status and disease progression.

AbstractWe aimed to evaluate the gender‐specific associations of malocclusion traits with oral health‐related quality of life (OHRQoL) among Finnish adults. Data were obtained from the Health 2000 Survey, Finland. Included participants (n = 3993) were ≥30 years old with OHRQoL and occlusion data. OHRQoL was measured using the 14‐item Oral Health Impact Profile (OHIP‐14). OHIP‐14 severity mean score, prevalence of impacts, and means of seven dimensions were outcomes. Explanatory variables were any malocclusion trait, increased overjet, negative overjet, open bite, deep bite, and crossbite/scissor bite. Logistic (prevalence) and cumulative (severity) regression models were adjusted for age, decayed teeth, deep periodontal pocket, occluding pairs, orthodontic treatment, and self‐perceived health. Gender modified the association between any malocclusion trait and OHRQoL, with the association being stronger in females. Females without any malocclusion trait (OR = 1.62, 95% CI = 1.14–2.28) or without crossbite/scissor bite (OR = 1.68, 95% CI = 1.16–2.43) had better OHRQoL (lower prevalence) than those with malocclusions. Males without increased overjet (OR 1.50, 95% CI = 1.04–2.17) had lower mean OHIP‐14 severity score than males with increased overjet, after adjustments. The association between psychological and physical disability and malocclusion traits was different between males and females. Gender differences in the impact of malocclusion traits should be considered when assessing orthodontic treatment need.
