PeMNet for Pectoral Muscle Segmentation

Simple Summary Deep learning has become a popular technique in modern computer-aided (CAD) systems. In breast cancer CAD systems, breast pectoral segmentation is an important procedure to remove unwanted pectoral muscle in the images. In recent decades, there are numerous studies aiming at developing efficient and accurate methods for pectoral muscle segmentation. However, some methods heavily rely on manually crafted features that can easily lead to segmentation failure. Moreover, deep learning-based methods are still suffering from poor performance at high computational costs. Therefore, we propose a novel deep learning segmentation framework to provide fast and accurate pectoral muscle segmentation result. In the proposed framework, the novel network architecture enables more useful information to be used and therefore improve the segmentation results. The experimental results using two public datasets validated the effectiveness of the proposed network. Abstract As an important imaging modality, mammography is considered to be the global gold standard for early detection of breast cancer. Computer-Aided (CAD) systems have played a crucial role in facilitating quicker diagnostic procedures, which otherwise could take weeks if only radiologists were involved. In some of these CAD systems, breast pectoral segmentation is required for breast region partition from breast pectoral muscle for specific analysis tasks. Therefore, accurate and efficient breast pectoral muscle segmentation frameworks are in high demand. Here, we proposed a novel deep learning framework, which we code-named PeMNet, for breast pectoral muscle segmentation in mammography images. In the proposed PeMNet, we integrated a novel attention module called the Global Channel Attention Module (GCAM), which can effectively improve the segmentation performance of Deeplabv3+ using minimal parameter overheads. In GCAM, channel attention maps (CAMs) are first extracted by concatenating feature maps after paralleled global average pooling and global maximum pooling operation. CAMs are then refined and scaled up by multi-layer perceptron (MLP) for elementwise multiplication with CAMs in next feature level. By iteratively repeating this procedure, the global CAMs (GCAMs) are then formed and multiplied elementwise with final feature maps to lead to final segmentation. By doing so, CAMs in early stages of a deep convolution network can be effectively passed on to later stages of the network and therefore leads to better information usage. The experiments on a merged dataset derived from two datasets, INbreast and OPTIMAM, showed that PeMNet greatly outperformed state-of-the-art methods by achieving an IoU of 97.46%, global pixel accuracy of 99.48%, Dice similarity coefficient of 96.30%, and Jaccard of 93.33%, respectively.
SwordNet: Chinese Character Font Style Recognition Network

Chinese characters have been created into many font styles in the long history, such as official script, running script, regular script and other standard computer font styles. Some famous calligraphers such as Ouyang Xun and Yan Zhenqing have produced many beautiful calligraphic works. Being able to detect and recognize these font styles quickly and accurately has many important applications in different use cases. In this paper, we present a sword-like model based on convolutional neural network with a sword structure to recognize font styles for Chinese characters. This model includes 15 convolutional layers. For each layer, we gradually increase the number of convolutional kernels to better extract the classification features of the input image.We use 4 downsampling layers in the model. For each downsampling operation, the length and width of the image become half of their original values while the number of channels gradually increases, leading to a sword-like shape. As a result, we name our model as SwordNet. We also created a Chinese font dataset called Nankai Chinese Font Style dataset, and made it available on Github. Using the above dataset, we compared the accuracy of our model with six other state-of-the-art network models. The experiments showed that SwordNet can achieve an average recognition accuracy of 99.03% in multiple experiments, while the other six models can only achieve accurary up to 94.91%. We concluded that SwordNet can perform better in font style recognition than other models.
Aqueous Allium sativum (garlic) extract ameliorated CdCl2- induced alterations in blood formation and spermatogenesis in albino rats

Purpose: To investigate the ameliorative effect of aqueous garlic extract (AGEx) on cadmium chloride (CdCl2-induced) alterations in the blood and testicles of rats. Methods: A total of 24 male rats (160 - 200 g), randomly assigned into 4 groups (A - D; n = 6), were used to investigate the claimed protective effect of AGEx on blood and spermatogenic tissues following CdCl2-intoxication in albino rats. The rats in Group A served as controls and were given 5 mg/mL of deionized water. Group B rats were given 300 mg/kg of AGEx. Group C rats were given 2 mg/kg of CdCl2. Rats in Group D first received 2 mg/kg of CdCl2, and 300 mg/kg of AGEx 2 h later. All treatments were done every 48 h for a period of six weeks. Results: CdCl2 administration to group C rats reduced (p < 0.05) haematocrit value (PCV), concentration of haemoglobin (Hb), red cells count (RBC), total leucocytes count (tWBC), eosinophil, neutrophil, testicular weights and sperm reserves; but elevated (p < 0.05) lymphocytes count compared with the controls. AGEx 300 mg/kg in group D rats significantly reversed (p < 0.05) the altered parameters compared with the controls. Conclusion: The results demonstrate that administration of aqueous Allium sativum (garlic) extract to male rats enhances spermatogenesis, and ameliorates testicular and haematological alterations induced by cadmium poisoning. Therefore, the spermatogenic principle in AGEx is a potential candidate for the clinical management of male infertility.
Heat Modulation of Intrinsic MR Contrasts for Tumor Characterization

Simple Summary Multi-parametric magnetic resonance imaging (MRI) is a paradigm that combines several MR imaging contrast types to provide added layers of information for the characterization of tissue types, including benign and malignant tumors. The approach detailed in this manuscript evaluates heat-induced changes in intrinsic MRI contrast types in vivo for tumor characterization. Specifically, the quantitative longitudinal relaxation time (T1), transverse relaxation time (T2), water proton chemical shift (CS), and apparent diffusion coefficient (ADC) were measured at various temperatures for benign and malignant tumors in rats. Results indicate that heat-induced changes in these intrinsic contrast types can potentially improve MR imaging visualization and characterization of tumor tissue. The approach detailed here may have a strong impact on real-time interventional procedures where tumor boundaries need to be accurately delineated to maximize positive therapeutic response for MRI-guided focal therapy. Abstract (1) Background: The longitudinal relaxation time (T1), transverse relaxation time (T2), water proton chemical shift (CS), and apparent diffusion coefficient (ADC) are MR quantities that change with temperature. In this work, we investigate heat-induced intrinsic MR contrast types to add salient information to conventional MR imaging to improve tumor characterization. (2) Methods: Imaging tests were performed in vivo using different rat tumor models. The rats were cooled/heated to steady-state temperatures from 26–36 °C and quantitative measurements of T1, T2, and ADC were obtained. Temperature maps were measured using the proton resonance frequency shift (PRFS) method during the heating and cooling cycles. (3) Results: All tissue samples show repeatable relaxation parameter measurement over a range of 26–36 °C. Most notably, we observed a more than 3.3% change in T1/°C in breast adenocarcinoma tumors compared to a 1% change in benign breast fibroadenoma lesions. In addition, we note distinct values of T2/°C change for rat prostate carcinoma cells compared to benign tissue. (4) Conclusion: These findings suggest the possibility of improving MR imaging visualization and characterization of tissue with heat-induced contrast types. Specifically, these results suggest that the temporal thermal responses of heat-sensitive MR imaging contrast mechanisms in different tissue types contain information for improved (i) characterization of tumor/tissue boundaries for diagnostic and therapy purposes, and (ii) characterization of salient behavior of tissues, e.g., malignant versus benign tumors.
Effect of sperm DNA fragmentation on blastocyst formation rate and subsequent IVF outcome

Background: Male infertility associated with sperm DNA alteration has raised a new issue in assisted reproduction techniques (ARTs). Methods: It was a retrospective analytical study on 250 cases of routine IVF/ICSI performed at Swagat ART Centre from January 2017 to January 2020. We divided the patient according to the sperm DNA fragmentation index (DFI) as normal DFI≤15%, n=95, a moderate DFI≤30%, n=89, and a high DFI group >30%, n=66. Oocytes of each patient were almost equally divided and fertilization method was adopted as half IVF half ICSI or only ICSI in poor quality (oligo, astheno, teratozoospermia or with two or all three defect and compared the fertilization, cleavage, embryo formation, blastocyst formation, pregnancy and early embryo formation rate among these six groups. Results: Fertilization, cleavage, embryo formation, and clinical pregnancy rates were reported as higher in ≤15% DFI group of both IVF and ICSI-ET (87.3±26.2, 77.7±26.1, 68.2±28.8, 50.8 in IVF and 78.3±17.8, 70.3±31.2, 67.2±28.8, 57.6 respectively). Significant differences (p<0.01) are observed among all six groups. Higher abortion rate is observed in high DFI group of both IVF and ICSI.Conclusions: High sperm DFI causes low blastocyst formation and pregnancy outcome. Higher abortion rate observed in high DFI group indicated need of further study.
Cyclin-Dependent Kinases and CTD Phosphatases in Cell Cycle Transcriptional Control: Conservation across Eukaryotic Kingdoms and Uniqueness to Plants

Cell cycle control is vital for cell proliferation in all eukaryotic organisms. The entire cell cycle can be conceptually separated into four distinct phases, Gap 1 (G1), DNA synthesis (S), G2, and mitosis (M), which progress sequentially. The precise control of transcription, in particular, at the G1 to S and G2 to M transitions, is crucial for the synthesis of many phase-specific proteins, to ensure orderly progression throughout the cell cycle. This mini-review highlights highly conserved transcriptional regulators that are shared in budding yeast (Saccharomyces cerevisiae), Arabidopsis thaliana model plant, and humans, which have been separated for more than a billion years of evolution. These include structurally and/or functionally conserved regulators cyclin-dependent kinases (CDKs), RNA polymerase II C-terminal domain (CTD) phosphatases, and the classical versus shortcut models of Pol II transcriptional control. A few of CDKs and CTD phosphatases counteract to control the Pol II CTD Ser phosphorylation codes and are considered critical regulators of Pol II transcriptional process from initiation to elongation and termination. The functions of plant-unique CDKs and CTD phosphatases in relation to cell division are also briefly summarized. Future studies towards testing a cooperative transcriptional mechanism, which is proposed here and involves sequence-specific transcription factors and the shortcut model of Pol II CTD code modulation, across the three eukaryotic kingdoms will reveal how individual organisms achieve the most productive, large-scale transcription of phase-specific genes required for orderly progression throughout the entire cell cycle.
Analysis Method of Bending Effect on Transmission Characteristics of Ultra-Low-Profile Rectangular Microstrip Antenna

With the advent of wearable communication devices, microstrip antennas have developed multiple applications due to their ultra-low-profile properties. Therefore, it is essential to analyze the problem of frequency shift and impedance mismatch when the antenna is bent. For the case of a rectangular patch antenna E-plane bent on the cylindrical surface, (1) this paper introduces the effective dielectric constant into the cavity model, which can accurately predict the resonance frequency of the antenna, and (2) according to the equivalent circuit model of the antenna resonance mode, the lumped element parameters are calculated based on the above effective dielectric constant, so that impedance characteristics and the S-parameter matching the port can be quickly constructed. From the perspective of circuit frequency characteristics, it explains the change in the transmission performance of the curved antenna. The experimental results show that the maximum difference between the experimental and theoretical calculation frequencies is less than 1%. These results verify the validity and applicability of the theory in the analysis of ultra-low-profile patch antennas and wearable electronic communication devices. It provides a theoretical basis for the fast impedance matching of patch antennas under different working conditions.

A Rapid Water Sliding Robot Optimized by Bionic Motion Trajectory

Water striders slide agilely and quickly on the water surface with the spatial elliptical rowing trajectory, it has attracted the research interest of scholars. But the existing bionic robots did not realize the level of it and generally suffer from slow speed and weak load capacity. Inspired by the trajectory of the water strider, the influence of its shape, size and velocity to the robot speed was analyzed by the numerical method. Based on the optimization parameters, the dexterous driving mechanism with a single motor is designed to achieve the spatial elliptical rowing trajectory within the restricted size and weight. The robot is manufactured with a mass and load capacity of 863 g and 600 g, respectively. The experiment of the sliding motion on the water was carried out. Its forward and turning speed are 625 mm/s and 45 /s respectively, and the speed/body length ratio is higher than the other similar robots. It also has been verified that the robot can slide in the disturbance environment with wind speed of 2.3 m/s and wave height of 210 mm.
Power Reduction in Punch-Through Current-Based Electro-Thermal Annealing in Gate-All-Around FETs

Device guidelines for reducing power with punch-through current annealing in gate-all-around (GAA) FETs were investigated based on three-dimensional (3D) simulations. We studied and compared how different geometric dimensions and materials of GAA FETs impact heat management when down-scaling. In order to maximize power efficiency during electro-thermal annealing (ETA), applying gate module engineering was more suitable than engineering the isolation or source drain modules.
Changes in foliage biomass of the genera Larix and Pinus along gradients of temperature and precipitation in Eurasia

Forest ecosystems are an essential part of the global carbon cycle and constitute a large fraction of the storage of terrestrial carbon. However, climate change may induce shifts in temperature and precipitation. These changes in temperature and precipitation have pronounced consequences for forest growth and carbon sequestration potential. This study addressed the comparative analysis of foliage biomass in the deciduous genus Larix spp. and the evergreen subgenus Pinus spp. in gradients of annual precipitation and winter temperature. The database for modeling involved 400 and 2,110 sample plots for Larch and Pine, respectively. Pine had reduced foliage biomass in dry conditions; however, an increase in foliage biomass was observed in moist conditions. On the contrary, regardless of conditions, Larix accumulated more foliage biomass. Interestingly, precipitation (100mm) increased Pine tree foliage biomass in warm regions. This positive trend of precipitation was observed for Larch in warm regions. We argue that these responses are related to the differences in physiology. In winter, Larch carries out only respiration. We discuss that these responses are due to the different status of tree needles in these two species. Understanding tree genera responses to rising temperature and shifts in precipitation regimes will enable us to improve predictions of the carbon storage potential in Eurasian forests.
