A Deep Learning Enabled Multi-Class Plant Disease Detection Model Based on Computer Vision

In this paper, a deep learning enabled object detection model for multi-class plant disease has been proposed based on a state-of-the-art computer vision algorithm. While most existing models are limited to disease detection on a large scale, the current model addresses the accurate detection of fine-grained, multi-scale early disease detection. The proposed model has been improved to optimize for both detection speed and accuracy and applied to multi-class apple plant disease detection in the real environment. The mean average precision (mAP) and F1-score of the detection model reached up to 91.2% and 95.9%, respectively, at a detection rate of 56.9 FPS. The overall detection result demonstrates that the current algorithm significantly outperforms the state-of-the-art detection model with a 9.05% increase in precision and 7.6% increase in F1-score. The proposed model can be employed as an effective and efficient method to detect different apple plant diseases under complex orchard scenarios.
Prevalence of resistant Staphylococcus aureus strains in frozen meat and their control using phytosynthesized selenium nanoparticles

Staphylococcus aureus continually threatens the safety of meat products, especially the multidrug-resistant (MDR) strains. The screening of MDR S. aureus prevalence in marketed meat products in Saudi Arabia was conducted via molecular identification of resistance genes (cfr, gyrA, and gyrB) that occurred in isolated bacteria. The green phytosynthesis of selenium nanoparticles (Se-NPs) was also conducted, using the fruits’ extract of Phyllanthus Emblica (PeE), for their evaluation as antibacterial nanocomposites against MDR S. aureus isolates. The prevalence percentage (PP) of S. aureus in meat samples was 14.2%, where the MDR S. aureus prevalence was 9.2%. The highest prevalence of S. aureus isolates was attained from minced meat samples, whereas the highest PP for multidrug-resistant (MDR) S. aureus was recorded from sausages samples. The PeE-synthesized Se-NPs had negative charges, spherical shapes, and well-disperssion with mean diameters of 11.98 nm. The anti- S. aureus activities of PeE, phytosynthesized Se-NPs, and their composite (PeE/Se-NPs) were proved qualitatively and quantitatively against the different standard and MDR strains, the antibacterial action of PeE/Se-NPs was the strongest. The treatment of MDR S. aureus with PeE/Se-NPs led to severe cells’ lyses/explosion after 8 h of exposure. The nanocomposites from PeE/Se-NPs are recommended for controlling MDR S. aureus in meat.
Hirnantia Fauna from the Condroz Inlier, Belgium: another case of a relict Ordovician shelly fauna in the Silurian?

Abstract. The end-Ordovician mass extinction, linked to a major glaciation, led to deep changes in Hirnantian–Rhuddanian biotas. The Hirnantia Fauna, the first of two Hirnantian survival brachiopod-dominated communities, characterizes the lower–mid Hirnantian deposits globally, and its distribution is essential to understand how the extinction took place. In this paper, we describe, illustrate, and discuss the first macrofossiliferous Hirnantia Fauna assemblage from Belgium, occurring in the Tihange Member of the Fosses Formation at Tihange (Huy), within the Central Condroz Inlier. Six fossiliferous beds have yielded a low-diversity, brachiopod-dominated association. In addition to the brachiopods (Eostropheodonta hirnantensis, Plectothyrella crassicosta, Hirnantia sp., and Trucizetina? sp.), one trilobite (Mucronaspis sp.), four pelmatozoans (Xenocrinus sp., Cyclocharax [col.] paucicrenulatus, Conspectocrinus [col.] celticus, and Pentagonocyclicus [col.] sp.), three graptolites (Cystograptus ancestralis, Normalograptus normalis, and ? Metabolograptus sp.), together with indeterminate machaeridians and bryozoans were identified. The graptolite assemblage, from the Akidograptus ascensus-Parakidograptus acuminatus Biozone, indicates an early Rhuddanian (Silurian) age, and thus, an unexpectedly late occurrence of a typical Hirnantia Fauna. This Belgian association may represent an additional example of relict Hirnantia Fauna in the Silurian, sharing characteristics with the only other known from Rhuddanian rocks at Yewdale Beck (Lake District, England), although reworking has not been completely ruled out. The survival of these Hirnantian taxa into the Silurian might be linked to delayed post-glacial effects of rising temperature and sea-level, which may have favored the establishment of refugia in these two particular regions that were paleogeographically close during the Late Ordovician–early Silurian.

Phase-sensitive radar as a tool for measuring firn compaction

Abstract Firn compaction models inform mass-balance estimates and paleo-climate reconstructions, but current models introduce key uncertainties. For example, models disagree on the dependence of density and compaction on accumulation rate. Observations of compaction to test these models are rare, partly because in situ methods for measuring englacial strain are time-consuming and expensive. Moreover, shallow measurements may confound strain due to compaction with strain due to ice-sheet flow. We show that phase-sensitive radio-echo sounder (pRES) systems, typically deployed to measure sub-shelf melting or ice-sheet deformation, can be used to measure firn compaction and test firn models. We present two complementary methods for extracting compaction information from pRES data, along with a method for comparing compaction models to pRES observations. The methods make different assumptions about the density structure and vary in their need for independent density measurements. Compaction profiles computed from pRES data collected on three ice rises in West Antarctica are largely consistent with measured densities and a physics-based model. With their minimal logistic requirements, new pRES systems, such as autonomous pRES, could be inexpensively deployed to monitor firn compaction more widely. Existing phase-sensitive radar data may contain compaction information even when surveys targeted other processes.
Community satisfaction with Enhanced Community Health Workers Activities in Mukono District, Uganda

Background Although the community health workers’ (CHWs) / volunteer health teams’ (VHTs) work is widely appreciated, some households do resist their interventions, and figures of authority sometimes question their manner and ability. Despite critical shortage of health workers’ world-over, little has been done to explore whether community health workers satisfy the people they serve. To fill this VHT training and support gap, Omni Med Uganda, a local Non-Governmental Organization in Uganda, has been implementing an enhanced hybrid VHT program since 2008. This study aimed at assessing community satisfaction with the CHW activities involved the enhanced CHW program. Materials and methods A cross-sectional study was employed. Qualitative data was collected from 217 participants using semi-structured questionnaires. Descriptive statistics such as frequencies, proportions, and means were performed for socio-demographic characteristics, Community satisfaction, and CHW activities. Prevalence Ratios (PR) were used to determine association between Community satisfaction and enhanced CHW activities. Results Majority of the respondents 81.1% (176/217) reported that the performance of the CHWs was satisfactory to maintain their health and that of their families. CHW activities such as confirming sick persons (APR:1.26 :95%CI (1.01–1.44), mobilization for cook stove building, (APR: 1.18: 95%CI (1.04–1.34), and monthly visits at participant’s homes (APR: 1.17: 95%CI (1.01–1.35) were positively associated with community satisfaction. Conclusion Enhancement of CHW activities should be considered during CHW programs. However, CHW performance should also be considered because community satisfaction does not imply high performance by CHWs and adherence to health interventions by the community.
Interactions between Food Environment and (Un)healthy Consumption: Evidence along a Rural-Urban Transect in Viet Nam

There is limited evidence on food environment in low and middle-income countries (LMICs) and the application of food environment frameworks and associated metrics in such settings. Our study examines how food environment varies across an urban-peri-urban-rural gradient from three sites in North Viet Nam and its relationship with child undernutrition status and household consumption of processed food. By comparing three food environments, we present a picture of the food environment in a typical emerging economy with specific features such as non-market food sources (own production and food transfers) and dominance of the informal retail sector. We combined quantitative data (static geospatial data at neighborhood level and household survey) and qualitative data (in-depth interviews with shoppers). We found that across the three study sites, traditional open and street markets remain the most important outlets for respondents. Contrary to the common concern that urban households are the major consumers of processed foods, peri-urban and rural areas on average had higher consumption of ultra-processed foods than in urban areas. The low price levels of processed foods and the presence of processed foods even among the traditional convenience stores, those in closest proximity to the rural households, offer potential explanations of this result. Regarding undernutrition, low retail diversity and a household’s dependence on own production have important implications for the high prevalence of child undernutrition in rural areas. Our findings add to the current discussion on the critical role of the food environment on nutrition, such as the potential link between economic marginalization and access to food, and the role of food supply channels in consumption of processed foods.
Impact of Jordanelle Dam on sedimentological and ecohydrological regimes of the Provo River, Utah, USA

ABSTRACT The impact of large dams primarily built in the 1950s and 1960s has been extensively studied; more recent dam construction often occurs alongside habitat restoration activities, which have the potential to mitigate impacts. Jordanelle Dam on the Provo River, constructed in 1992, is economically and ecologically important to the region. This study aims to elucidate the effects of the dam on the sediment distribution and mobility of the river to inform future management of the system. Due to decreased flows, gravels (D16, D50) downstream of the dam are generally larger and subsurface grains are significantly coarser (p < 0.05), than those upstream of the dam. Further, the flow required to mobilize sediment is larger downstream of the dam and occurs rarely, leading to less mobile sediment and a more stable channel. The reduced mobility of sediment below the dam has decreased channel complexity. Much of the mobile sediment below the dam may be supplied from an unaltered river reach, rather than upstream mobilization. This sediment is vital to trout habitat, an important aspect of the recreation economy of the region. Monitoring changes in grain size distribution below the dam is necessary to prevent the loss of this valuable resource through diminished spawning habitat.
Liquid Force and Rupture Distance between Two Particles

The study of liquid force has a special meaning to industrial manufacturing. By taking the liquid bridges between equal and unequal particles as objects, the liquid force-displacement curves were measured and recorded by using a novel Nano UTM T150 tensile system. The influences of diameter, diameter ratio, liquid volume, and the surface tension on the liquid force-distance curve, the maximum liquid force, and rupture distance were compared and sorted. The results show that the maximum liquid force and rupture distance both increase with the increase in liquid volume, particle diameter, diameter ratio, and surface tension. The diameter plays a decisive role in determining the value of the maximum liquid force compared with surface tension and liquid volume, which only influence the force value in a local range. The rupture distance shows a positive correlation with liquid volume and surface tension and a negative correlation with the diameter or diameter ratio. The maximum liquid force between unequal particles is about half of the sum of the force between the equal spheres of larger and smaller size in that system.
Autoimmunity Is a Significant Feature of Idiopathic Pulmonary Arterial Hypertension

Rationale Autoimmunity is believed to play a role in idiopathic pulmonary arterial hypertension (IPAH). It is not clear whether this is causative or a bystander of disease and if it carries any prognostic or treatment significance. Objectives To study autoimmunity in IPAH using a large cross-sectional cohort. Methods Assessment of the circulating immune cell phenotype was undertaken using flow cytometry, and the profile of serum immunoglobulins was generated using a standardized multiplex array of 19 clinically validated autoantibodies in 473 cases and 946 control subjects. Additional glutathione S-transferase fusion array and ELISA data were used to identify a serum autoantibody to BMPR2 (bone morphogenetic protein receptor type 2). Clustering analyses and clinical correlations were used to determine associations between immunogenicity and clinical outcomes. Measurements and Main Results Flow cytometric immune profiling demonstrates that IPAH is associated with an altered humoral immune response in addition to raised IgG3. Multiplexed autoantibodies were significantly raised in IPAH, and clustering demonstrated three distinct clusters: “high autoantibody,” “low autoantibody,” and a small “intermediate” cluster exhibiting high concentrations of ribonucleic protein complex. The high-autoantibody cluster had worse hemodynamics but improved survival. A small subset of patients demonstrated immunoglobulin reactivity to BMPR2. Conclusions This study establishes aberrant immune regulation and presence of autoantibodies as key features in the profile of a significant proportion of patients with IPAH and is associated with clinical outcomes.
Measuring dimensions of perceived business success among Malaysian and Bangladeshi SME owners

PurposeThe purpose of this study is to examine the perceptions of Malaysian and Bangladeshi retail small- and medium-sized enterprise (SME) business owners on the key elements of business growth.Design/methodology/approachThe construct measurements have all been taken from previous researches. The data were gathered from retail SMEs in Malaysia and Bangladesh in order to evaluate entrepreneurs' perception towards the essential elements of a business performance. Structural equation modeling (SEM) with PLS-technique, specifically Smart-PLS Version 3.2. 4, was used to accomplish the study's objectives and analyze the measurements, as well as the structural model.FindingsAccording to the findings, Malaysian and Bangladeshi SMEs have different perspectives toward the dimensions of their business performance. For example, Malaysian retail SME owners consider business growth and financial results to be the most important aspects of their success. Retailers consider financial performance to be less critical than non-financial performance when it comes to their business's success. Owners of Bangladeshi retail SMEs, on the other hand, see efficiency relative to competition, and that non-financial performance is the key component to achieving business success. In the sense of Bangladeshi SMEs, market development and financial results are seen as less significant in attaining success.Research limitations/implicationsSince this research was only conducted in Malaysia and Bangladesh, it did not cover a large number of countries. The sample size was limited; therefore, the findings of this study cannot be applied to the entire population of Malaysian and Bangladeshi retail SMEs due to the non-probability sampling technique.Practical implicationsThe findings of this study show that entrepreneurs or business owners in the retail sector in Malaysian and Bangladeshi SMEs view the attributes of their business performance differently.Originality/valueThis study adds to the rising context of entrepreneurship by examining SME owners' perception of main business performance dimensions in the scope of Asian retail SMEs.
Determining the relative risk of hospitalisation and surgery of fall injury patients

ABSTRACT Falls are one of the most common cause of nonfatal and fatal injuries in the U.S. costing over an estimated $54 billion annually. A significant percentage of patients presenting to hospital emergency departments (ED) for falls are hospitalised. This paper analyzes a regional hospital data pertaining to adults presenting to the ED because of falls. We use patient demographics and medical conditions to help identify patients at risk for immediate undesirable outcomes after a fall. Furthermore, we determine the relative risk of patient hospitalisation and surgery and their characteristics. Our results indicate that older patient’s, patients arriving by ambulance, patients with higher severity levels and patients with pre-existing comorbidities were at a higher relative risk of hospitalisation and surgery. Furthermore, patients with medical conditions pertaining to femur and tibia fractures, pelvis, renal failure, ambulatory dysfunction, and cellulitis, among others, and non-Hispanic whites were at a much higher relative risk of hospitalisation and surgery.
Defect-engineered ring laser harmonic frequency combs

A monochromatic wave that circulates in a nonlinear and dispersive optical cavity can become unstable and form a structured waveform. This phenomenon, known as modulation instability, was encountered in ﬁber lasers, optically pumped Kerr microresonators and, most recently, in monolithic ring quantum cascade lasers (QCLs). In ring QCLs, the instability led to generation of fundamental frequency combs—optical ﬁelds that repeat themselves once per cavity round trip. Here we showthat the sameinstability may alsoresult inself-starting harmonic frequency combs—waveforms that repeat themselves multiple times per round trip, akin to perfect soliton crystals in ring Kerr microresonators. We can tailor the inter-mode spacing of harmonic frequency combs by placing two minute defects with a well-deﬁned separation between them along the ring waveguide. On-demand excitation of frequency comb states with few powerful modes spaced by hundreds of gigahertzmayﬁndtheiruseinfuturesub-terahertzgenerators.
Recurvature and movement processes of tropical cyclones over the Bay of Bengal

Active bimodal tropical cyclones (TCs) are embedded in nonuniform flows over the Bay of Bengal (BoB). More than half of the TCs that occurred from 1990 to 2019 recurved from their original path due to the influence of 500–300 hPa steering flows. Premonsoon TCs have a tendency to turn right and make landfall on the right‐side coastal areas of the BoB. On the other hand, most of the TCs that occurred in the postmonsoon season crossed the left coast or east coast of India, despite being left or right from their path. The simulation shows that Cyclone Roanu (2016) was driven by a warm, moist, unstable southwesterly that was blocked and diverted by the hot, dry stable air masses of northerlies and northwesterlies. As a result, the TC moved along the dry–moist boundary, keeping a constant distance of ∼400 km between the eye and dryline. Conversely, the combined steering of moist southeasterly and southward‐moving upper‐level westerly jets controlled the track of postmonsoon Cyclone Madi (2013), encompassing a left turn of ∼150°. In addition to the primary steering mechanism, TC vortex propagation can be explained by the strong vertical shear (>30 m·s−1) offered by the dryline during the premonsoon period and near the monsoon trough in the postmonsoon period. This vertical shear causes the upper‐level anticyclone to tilt downshear, resulting in the forward motion of the TC vortex. The deep convection and associated mesovortices, especially those that are more prominent along the dryline, additionally influence asymmetric diabatic heating, contributing to the advection of TC potential vorticity.
Holes in the spinous processes of woolly mammoth vertebrae: spatial and temporal distribution, and the causes of pathology formation

The latest data on holes in the spinous processes of the vertebrae of woolly mammoths, a rare pathology, are presented. This was identified at 19 sites of northern Eurasia. Such destructive changes are recorded ca. 34–12k 14C a bp, and only two sites dated to >50k and >41k 14C a bp. The main hypotheses about hole formation are: vertebral abnormalities; bone infections; genetic traits; and unfavourable geochemical environment. The pathology occurred in mammoths of all age groups, and could have arisen at the embryonic stage. There are two types: classic holes associated with osteolytic changes; and very rarely tumour‐like lesions. The most likely cause of the lesions is alimentary osteodystrophy caused by chronic mineral starvation. The aetiology of this disease is usually associated with a deficiency or excess of macro‐ and microelements in the geochemical landscape, and through forage and water this leads to a severe metabolic disorder. Analysis of palaeopathological data shows two waves of geochemical stress in animals, ca. 26–18k and ca. 16–12k 14C a bp. Therefore, the woolly mammoth extinction can be viewed as a non‐linear function, with two peaks of high mortality corresponding to the Last Glacial Maximum and the Lateglacial.
‘But I feel more at home in the Deaf world even if I can talk’: D/deaf adolescents’ experiences of transitioning from a mainstream school to a Deaf school in Sweden

ABSTRACT Since the late 1990s, the majority of D/deaf students enter schooling in a mainstream setting. Little has been written about their experiences and how a change in school settings impacts their learning and social identity. In this study, semi-structured interviews have been conducted with nine students, and the results show that their time in a mainstream school setting has led them to construct a marginal or negative social identity, but after transitioning to a Deaf school, the social identity has shifted towards a positive one. According to students, this is due to feelings of belonging as equal members of the social group where they are given the opportunity to develop language skills that allow them to communicate without restrictions. The students also report improvement in academic achievements as a result of the sign bilingual school setting. Parents and D/deaf students need to experience the different language settings to make an informed decision.
