AbstractInfrared solar cells are more effective than normal bandgap solar cells at reducing the spectral loss in the near-infrared region, thus also at broadening the absorption spectra and improving power conversion efficiency. PbS colloidal quantum dots (QDs) with tunable bandgap are ideal infrared photovoltaic materials. However, QD solar cell production suffers from small-area-based spin-coating fabrication methods and unstable QD ink. Herein, the QD ink stability mechanism was fully investigated according to Lewis acid–base theory and colloid stability theory. We further studied a mixed solvent system using dimethylformamide and butylamine, compatible with the scalable manufacture of method-blade coating. Based on the ink system, 100 cm2 of uniform and dense near-infrared PbS QDs (~ 0.96 eV) film was successfully prepared by blade coating. The average efficiencies of above absorber-based devices reached 11.14% under AM1.5G illumination, and the 800 nm-filtered efficiency achieved 4.28%. Both were the top values among blade coating method based devices. The newly developed ink showed excellent stability, and the device performance based on the ink stored for 7 h was similar to that of fresh ink. The matched solvent system for stable PbS QD ink represents a crucial step toward large area blade coating photoelectric devices.

Identifying Key Crop Growth Models for Rain-Fed Potato (Solanum tuberosum L.) Production Systems in Atlantic Canada: A Review with a Working Example
Authors: Islam Mohammad , Li Sheng 
Published: October 2023

AbstractThe selective use of potato crop models is a key factor in increasing potato production. This requires a better understanding of the synergies and trade-off of crop management while accounting for the controlling effects of potato genetic and agro-climatic factors. Over the years, crop modeling for potato has relied on historical data and traditional management approaches. Improved modeling techniques have recently been exploited to target specific yield goals based on historical climatic records, future climate uncertainties and weather forecasts. However, climate change and new sources of information motivate better modeling strategies that might take advantage of the vast sources of information in the spectrum of actual, optimal and potential yield and potato management methodologies in a more systematic way. In this connection, two questions warrant interest: (i) how to deal with the variability of crop models relevant to their structure, data requirement and crop-soil-environmental factors, (ii) how to provide robustness to the selection process of a model for specific applications under unexpected change of their structure, data requirement and climatic factors. In this review, the different stages of potato model development are described. Thirty-three crop growth models are reviewed and their usage and characteristics are summarized. An overview of the literature is given, and a specific example is worked out for illustration purposes to identity key models suitable for potato management in the Atlantic provinces of Canada. Based on a categorical principal component analysis (CatPCA) procedure three potato models representing three principal components (PCs) were identified which will be useful for future potato production and yield simulation in this geographic area.

Published: October 2023

AbstractThe locoregional distribution patterns of lymphatic malformations (LM) in the upper extremity have not been described in the scientific literature. Twelve patients were diagnosed with a LM in their upper extremities between 1998 and 2021 at our center. In all cases, these were isolated malformations. Nine patients (75%) presented an ulnar distribution pattern of the LM, two (16.7%) presented a radial distribution pattern, and one (8.3%) presented involvement of both territories. We found no statistically significant differences in any sociodemographic or clinical variable between patients with ulnar or radial LM distribution patterns. In this work, we found that the ulnar distribution pattern was more frequent than the radial distribution pattern in upper extremity LM. Furthermore, we observed that LM in the radial territory appeared as lesions limited to the distal segment of the upper limb (thumb and distal radius). This is a small retrospective case series and therefore, these findings should be interpreted with caution. Larger sample size studies are necessary to validate and characterize this finding.

Published: October 2023

AbstractRenal dysfunction is a common complication of MM and is associated with poor prognosis, particularly when progressive. Early identification of renal dysfunction is essential for prompt treatment for disease control and restoration of renal function. Urinary insulin-like growth factor-binding protein 7 (IGFBP-7), urinary tissue inhibitor of matrix metalloproteinase 2 (TIMP-2), and serum transgelin levels were measured using enzyme-linked immunosorbent assays and evaluated as biomarkers for the prediction of renal impairment in patients with multiple myeloma. U IGFBP-7/creatinine ratio, U TIMP2/creatinine ratio, and serum transgelin levels were higher in patients with MM than healthy controls, and predicted renal insufficiency in MM. Serum transgelin, urinary IGFBp7, and TIMP2 levels may have utility as biomarkers of renal tubular injury and predict future renal impairment in patients with MM.

Published: October 2023

AbstractSecondary school staff are often tasked with delivering mental health content to students, yet there has been little research on staff confidence to do so. Given the responsibility placed on staff to support student mental health, reliable and valid measures are needed to facilitate assessment of teacher confidence in the classroom and evaluation of the impact of interventions designed to enhance teacher confidence and ultimately support the delivery of mental health interventions in schools. This study aimed to examine the psychometric properties of the Teacher Confidence Scale for Delivering Mental Health Content (TCS-MH) and the What Worries Me Scale (WWMS), both developed by Linden and Stuart (2019) and previously tested on a sample of elementary school teachers. Within this paper we examine the factor structure, reliability, and validity of these measures in a large sample (N = 644) of secondary school staff. Exploratory factor analysis suggested that each scale had a single factor structure with all original items retained. This was further supported with confirmatory factor analysis. Examination of the reliability of both scales found that they had good internal consistency. Finally, through correlation analyses, both measures demonstrated satisfactory convergent and discriminant validity from mental health knowledge, mental health stigma, general anxiety, and teacher efficacy. Both the TCS-MH and the WWMS show great promise as measures of secondary school staff confidence to deliver mental health content.
Analysis of using the modified centring plates with eccentric points for geodetic measurements
Authors: Kwinta Andrzej , Gargula Tadeusz 
Published: October 2023

AbstractMany engineering structures require high measurement accuracy. Their displacement and deformation are determined from the results of special measurements. For the measurements to be accurate, a properly constructed and marked survey network is necessary. The long-term stability of survey points can be ensured by marking (installing) them on solid rock or special triangulation pillars. Accurate and repeatable instrument positioning and premarking over the points is ensured by centring plates. Centring plates with eccentric points can be used when a survey involves several instruments. The article presents the results of measurements and computations done using centring plates with eccentric points. The measurements were conducted in a metrology laboratory. The sought points were premarked with prisms and reflective targets. The measuring methods were angular intersection, linear intersection, and linear-angular measurements. We computed coordinates for the measured points, and the results were compared to their known directory values. The results demonstrate that centring plates with eccentric points can be employed in engineering surveys.

Abstract
The palaeofloristic study of Gondwana sediments recovered from Religara area, South Karanpura Basin illustrates the macrofloral diversity in the area. Three distinct megafloral assemblages I, II, III are reported from freshly exposed coaly shale and carbonaceous shale layers of lower Barakar, upper Barakar and Raniganj formations of the basin. The assemblage comprises 72 species and thirteen genera of which 28 are newly reported species, which clearly exemplifies the macrofloral diversity over Permian Period in the studied area. The retrieved floral assemblages justified the existence of two interrelated ecosystems i.e., terrestrial and marshy. A gradual shifting of leaf morphology in reticulate leaves of order Glossopteridales illustrates biostratigraphic age as well as the shifting of climate during the deposition of sediments. The dominance of narrow mesh Glossopteris flora with the presence of typical Karharbari flora in the lowermost fossil horizon, illustrating the biostratigraphic age as late Artinskian (lower Barakar Formation). Likewise, the middle and upper floristic zones are dominated by Glossopteris of intermediate mesh form and broad mesh form suggesting biostratigraphic age as Kungurian (upper Barakar) and Wordian-Changhsingian (Raniganj) respectively. Deposition of in-situ Vertebraria depicts the autochthonous coal deposits and existence of some patches of palaeosol in the investigated location. The present investigation aims to infer the biostratigraphy, palaeoclimate, palaeoenvironment, palaeovegetational reconstruction of the basin during late Artinskian –Kungurian and Wordian- Changhsingian times.

Abstract
In this paper, preliminary studies on the failure analysis of hybrid composite materials utilizing acoustic emission and machine learning are presented. The main purpose of this study was to analyze the possibilities of using machine learning techniques as a way to better cluster the data obtained from acoustic emission. In this paper, we focus on data preparation, feature extraction (Laplacian score), determination of cluster number (Caliński–Harabasz, Silhouette, and Davies–Bouldin), and testing three clustering techniques, namely K-means, fuzzy C-means, and spectral clustering. The dataset was obtained by testing fiber metal laminates—composites consisting of metal and composite layers. Two experimental tests were realized on pre-cracked rectangular specimens—one with loading in mode I and one with loading in mode II (DCB—double cantilever beam and ENF—end-notch flexural test). Elastic waves were recorded during these tests via an acoustic emission system. Preliminary studies show that the proposed method can be used successfully to cluster data obtained in this way. The obtained dataset was split into 3 clusters (for the ENF test) and 5 clusters (DCB test). In the next stages of the research campaign, based on the presented results, we intend to change the approach to semi-supervised by running additional single-cause damage tests to enhance the achieved results and enable easier damage recognition.
A dual-path instance segmentation network based on nuclei contour in histology image

Published: October 2023

AbstractAccurate segmentation of nuclei in histology images is essential for digital pathology. However, previous work should have considered integrating nuclei contour information into network learning. The main problems are (1) nuclei contour information needs to be fully considered, resulting in inaccurate spatial location of nuclei. (2) Small nuclei in dense regions or irregularly shaped nuclei cannot be segmented. (3) Mainstream networks consider more long-distance semantic information and larger receptive fields and do not consider the fusion of feature maps with different semantics. To solve the above problems, we have proposed a contour-based dual-path instance segmentation network. Firstly we reconstructed the nuclei contour information using algorithms and morphological manipulations. Provide input for subsequent contouring networks. Then we designed a dual-path network. It can extract nuclei features and contour features independently in the encoding stage and fuse the feature maps at different scales in the decoding stage. In the decoding stage, we use the attention module with a newly designed fusion mechanism, which allows us to fuse different semantics of feature maps for simple and efficient fusion. Finally, using the watershed algorithm, we use the network segmentation results to get the instance segmentation results of the nuclei. We used four publicly available datasets, including Kumar, CPM-15, CPM-17, and TNBC, which contain the nuclei of many organs and different forms of nuclei in the human body. Compared with the mainstream methods, we obtained the best AJI metrics, which are 0.656,0.717, and 0.602. In conclocess can effectively improve the performance of the nuclei instance segmentation network. It can accurately locate the scattered nuclei in space with small segmented nuclei in dense regions.
Financial integration and economic growth: directional heterogeneity and threshold effect
Authors: Chen Chao , Kim Yoonbai 
Published: October 2023

AbstractDespite voluminous studies, the growth effects of international financial integration remain unresolved. Recent studies have shown that the effects depend on a wide variety of factors including the level of economic and financial development, the type of financial flows (debt or equity), the direction of flows (inflows or outflows), and the existence of the investment or saving constraint with the economy. In this paper, we implement a model that embodies double threshold effects where the thresholds are defined in terms of (i) per capita GDP and (ii) the economic growth rate. The results support the single threshold of the growth rate, which is expected to capture the existence of the investment or saving constraint with the economy. We find that developed and slowly developing economies are likely to benefit from capital outflows for higher investment incomes whereas emerging economies with growth rate higher than 3.4—5.7 percent can successfully take advantage of financial integration and resulting capital inflows. The findings are robust to changes in variable definition, model specification and data selection.

Abstract

Objective:
The study clarified differences in understanding and satisfaction between face-to-face and online training on radiation emergency medical preparedness (REMP) training.

Methods:
The training was held at Hirosaki University between 2018 and 2022, with 46 face-to-face participants and 25 online participants.

Results:
Face-to-face training was significantly more understandable than online for the use of the Geiger counter (P < 0.05), but the educational effect of virtual reality (VR) was not significantly different from the actual practice. For the team exercise of taking care of the victims, online resulted in a significantly higher understanding (P < 0.05).

Conclusions:
Interactive exercises can be done online with equipment sent to learners, and VR is also as effective. The use of videos was more effective for first-timers to learn the practical process from a bird’s-eye view, especially for team-based medical procedures.

Published: October 2023

AbstractObjective:To determine the effectiveness of active, upper-room, germicidal ultraviolet (GUV) devices in reducing bacterial contamination in patient rooms in air and on surfaces as a supplement to the central heating, ventilation, and air conditioning (HVAC) air handling unit (AHU) with MERV 14 filters and UV-C disinfection.Methods:This study was conducted in an academic medical center, burn intensive care unit (BICU), for 4 months in 2022. Room occupancy was monitored and recorded. In total, 402 preinstallation and postinstallation bacterial air and non–high-touch surface samples were obtained from 10 BICU patient rooms. Airborne particle counts were measured in the rooms, and bacterial air samples were obtained from the patient-room supply air vents and outdoor air, before and after the intervention. After preintervention samples were obtained, an active, upper-room, GUV air disinfection system was deployed in each of the patient rooms in the BICU.Results:The average levels of airborne bacteria of 395 CFU/m3 before GUV device installation and 37 CFU/m3 after installation indicated an 89% overall decrease (P < .0001). Levels of surface-borne bacteria were associated with a 69% decrease (P < .0001) after GUV device installation. Outdoor levels of airborne bacteria averaged 341 CFU/m3 in March before installation and 676 CFU/m3 in June after installation, but this increase was not significant (P = .517).Conclusions:Significant reductions in air and surface contamination occurred in all rooms and areas and were not associated with variations in outdoor air concentrations of bacteria. The significant decrease of surface bacteria is an unexpected benefit associated with in-room GUV air disinfection, which can potentially reduce overall bioburden.
Effects of integral length scale variations on the stall characteristics of a wing at high free-stream turbulence conditions
Authors: Thompson C. , Biler H. , Symon S. , Ganapathisubramani B. 
Published: October 2023

The effect of variations in the integral length scale of incoming free-stream turbulence on a NACA0012 wing is investigated with the use of force, moment and particle image velocimetry measurements. At a chord-based Reynolds number (

$Re = U_\infty c/\nu$

where c is the chord length,

$U_\infty$

is the free-stream velocity and

$\nu$

is the kinematic viscosity) of

$2\times 10^5$

, an active grid generates turbulence intensities of 15 % at normalised integral length scales ranging from 0.5

$c$

to 1

$c$

. The introduction of turbulence improves the time-averaged performance characteristics of the wing by delaying stall and increasing the peak lift coefficient. It is found that for half-chord integral length scales, the magnitude of the fluctuations in forces and moments is larger than that of full-chord integral length scales, as the former amplifies the naturally occurring unsteadiness in the flow (when there is no free-stream turbulence). The increase in magnitude is ascribed to a larger density of smaller-scale vortices within the separated flow and wake region of the wing.
Cross-Cultural Perceptions of Technology and Magic in the Ghost Dance, Boxer Uprising, and Maji Maji Rebellion
Authors: McEnroe Sean F. 
Published: October 2023

AbstractThis article explores the widespread phenomenon of anti-colonial movements that relied on magical rituals for protection against European weapons. It examines both the beliefs of the magical practitioners themselves, and those of colonizing observers whose fascination with stories of “primitive magic” contributed to their contrasting self-representations as superior beings in possession of technological wonders. North America’s Ghost Dance movement, China’s Boxer Rebellion, and East Africa’s Maji Maji uprising took place on three different continents but occurred almost simultaneously. The cases come from a narrow period of time, roughly 1890 to 1910, during a peak of colonial violence all over the world.
