The spread of infections and rot are crucial factors in the decrease tomato production. Accurately segmenting affected tomatoes real-time can prevent illnesses. However, environmental surface features affect segmentation accuracy. This study suggests an improved YOLOv8s-Seg network to perform effective fruit, color, features. feature fusion capability algorithm was by replacing C2f module with RepBlock (stacked RepConv), adding SimConv convolution (using ReLU function instead SiLU as...

An ultrasensitive refractive index (RI) sensor based on enhanced Vernier effect is proposed, which consists of two cascaded fiber core-offset pairs. One pair functions as a Mach-Zehnder interferometer (MZI), the other with larger core offset low-finesse Fabry-Perot (FPI). In traditional Vernier-effect sensors, an insensitive to environment change used sensing reference. Here in proposed sensor, interference fringes MZI and FPI shift opposite directions ambient RI varies, same direction...

Abstract In tomato producing fields, automated large-area detection method is critical for fruit health monitoring and harvesting. However, due to the limited feature information included in tomatoes, across long distances results more missing or incorrect detections. To address this issue, research proposes an improved YOLOv8 network, RSR-YOLO, long-distance identification of fruits. Firstly, paper designs a partial group convolution (PgConv) furthermore innovative FasterNet (IFN) module...

In this work, characteristics bionic surface delicate water-trapping microstructures...

Consider revising medium temperature used LM35 sensor, what is an economic and feasible method. This study mainly researches the applicability of sensor in soil testing field. Selected based on theoretical equation between output voltage Celsius temperature; introduced correction coefficient, carried through calibration experiment sensor; further more, it applied to potted rice's detection. The results show that, each coefficient different from others, but these numerical are close 1, linear...

MicroRNAs refer to small RNA molecules that destroy the messenger by binding on them inhibiting production of protein. However, role miR-155 in uveal melanoma metastasis remains largely unknown. In this study, we found was upregulated both cells and tissues. Transfection mimic into led an increase cell growth invasion; contrast, inhibition resulted opposite effects. Also, identified Nedd4-family interacting protein 1 as a direct target miR-155, expression inhibited miR-155. Furthermore,...

Reducing machinery surface friction resistance can improve the efficiency of energy utilization. The lotus leaf, as everyone knows, has a strong capacity for self-cleaning and hydrophobicity. In this paper, bionic leaf was prepared in large-area, its drag reduction performance studied by both numerical simulation experimental analysis. Experimental results showed that maximum rate 6.29% which appeared at velocity 3 m s-1. contact state between liquid changed from Cassie to Wenzel with...

To enhance the power conversion efficiency (PCE) and stability of all-polymer solar cells (all-PSCs), a new precursor solution based on an in situ chemical reaction nanomolybdenum powder (Mo), hydrogen peroxide (H2O2), ammonia (NH3·H2O) was developed for preparing MoO3 hole transport layer (HTL) all-PSCs. The results showed that PCE PM6:PY-IT HTL were better than those PEDOT:PSS layer. further understand relationship between device performance, ultrafast photophysical processes all-PSCs...

Abstract Underwater machinery withstands great resistance in the water, which can result consumption of a large amount power. Inspired by character that loach could move quickly mud, drag reduction mechanism Paramisgurnus dabryanus is discussed this paper. Subjected to compression and scraping water sediments, not only secrete lubricating mucus film, but also importantly, retain its well from losing rapidly through surface micro structure. In addition, it has been found flexible deformations...

Interest in the influence of musical training on executive functions (EFs) has been growing recent years. However, relationship between and EFs remains unclear. By dividing into inhibitory control, working memory, cognitive flexibility, this study systematically examined its association with children, further verified whether there was a sensitive period for music EFs. In Experiment 1, musically trained untrained children were asked to complete Go/No-go, Stroop, Continuous Performance,...

To explore the drying characteristics of soybean dregs and a nondestructive moisture content test method, in this study, were dried with hot air (80 °C), was measured using water status analyzed low-field nuclear magnetic resonance (LF-NMR) prediction models built validated. The results revealed that contents 0.57 0.01 g/g(w.b.), respectively, after for 5 7 h. effective diffusivity increased decrease content; it ranged from 5.27 × 10-9 to 6.96 10-8 m2·s-1. Soybean contained bound (T21),...

Patients with hepatocellular carcinoma (HCC) surgically resected are at risk of recurrence; however, the factors recurrence remain poorly understood. This study intended to establish a novel machine learning model based on clinical data for predicting early HCC after resection.A total 220 patients who underwent resection were enrolled. Classification models developed predict recurrence. The standard deviation, recall, and precision used assess model's accuracy identify efficiency...

The drag reduction design of underwater vehicles is great significance to saving energy and enhancing speed. In this paper, the characteristics Paramisgurnusdabryanus loach was explored using 3D ultra-depth field microscopy observe arrangement scales. Then, a geometric model established parameterized. A simulated sample processed by computer numerical control (CNC) machining tested through flow channel bench. pressure drop data were collected sensors, rate consequently calculated. test...

It has been reported that thoron levels in China are above the world average and may therefore make a significant contribution to natural background radiation dose. We conducted pilot study of concentrations both radon progeny during spring 2006 Beijing area, China. A new type portable 24 h integrating monitor with CR-39 detector was used survey. Seventy dwellings eight outdoor sites were measured For country houses built red bricks slurry, equilibrium equivalent (EEC) 1.02 ± 0.48 16.41 9.02...
