According to news reporting originating from Vitoria, Brazil, by NewsRx correspondents, research stated, "Even though artific ial intelligence and machine learning have demonstrated remarkable performances in medical image computing, their accountability and transparency level must be improved to transfer this success into clinical practice. The reliability of mac hine learning decisions must be explained and interpreted, especially for suppor ting the medical diagnosis." Our news editors obtained a quote from the research from the Department of Infor matics, "For this task, the deep learning techniques' black-box nature must some how be lightened up to clarify its promising results. Hence, we aim to investiga te the impact of the ResNet-50 deep convolutional design for Barrett's esophagus and adenocarcinoma classification. For such a task, and aiming at proposing a t wo-step learning technique, the output of each convolutional layer that composes the ResNet-50 architecture was trained and classified for further definition of layers that would provide more impact in the architecture. We showed that local information and high-dimensional features are essential to improve the classifi cation for our task."

Motion optimi zation of structural parameters and corresponding motion workspaces verification can be adopted to evaluate motion range and ability. Experiments can be utilize d to verify the rationality of theoretical modeling and optimization simulation of bionic scorpion robot arm. Experimental results illustrate that it is evident to demonstrate that the motion behaviors of bionic scorpion robot arm can be ve rified to be consistent with three key states of virtual theoretical motions. Th e key joints possessing minor errors may also be utilized to illustrate the rela tively excellent dynamic motions existing in bionic scorpion robot arm."

According to news reporting out of Madhya Pradesh, India, by NewsRx edito rs, research stated, "Hydraulic cylinders with higher stages of extraction are e xtensively used in earthmoving and heavy machines due to their longer stroke, sh orter retracted length, and high-end performance." Our news journalists obtained a quote from the research from Indian Institute of Technology Indore: "The rigorous and long hours of operations make cylinders pr one to internal leakage, which visually remains unnoticeable. This paper present s the conceptualization and realization of a newly developed 210 bar high-pressu re hydraulic test rig actuated by a two-stage hydraulic cylinder. Experiments ha ve been carried out to acquire pressure signals for two different leakage condit ions (3% and 5% for moderate and severe leakages res pectively) in the ramp wave motion of the cylinder. A decline in the working pre ssure and the piston velocity by approximately 10% and 45% for these leakage conditions respectively is noted. The time-frequency analysis infers these signals contain low-frequency components."

According to news reporting out of Nanjing, People's Republic of China, by NewsRx editors, research stated, "Spontaneous intracerebral hemorrhage (ICH) accounts for up to 20% of all strokes and results in 40% mortality at 30 days. Although conservative medical management is still the stan dard treatment for ICH patients with small hematoma, patients with residual hema toma 15 mL after surgery are associated with better functional outcomes and surv ival rates." Our news journalists obtained a quote from the research from the Nanjing Univers ity of Chinese Medicine, "This study reported our clinical experience with using Robotic Stereotactic Assistance (ROSA) as a safe and effective approach for ste reotactic ICH aspiration and intra-clot catheter placement. A retrospective anal ysis was conducted of patients with spontaneous ICH who underwent ROSA-guided IC H aspiration surgery. ROSA-guided ICH surgical techniques, an aspiration and int ra-clot catheter placement protocol, and a specific operative workflow (pre-oper ative protocol, intraoperative procedure and postoperative management) were empl oyed to aspirate ICH using the ROSA One Brain, and appropriate follow-up care wa s provided. From September 14, 2021 to May 4, 2022, a total of 7 patients were i ncluded in the study. Based on our workflow design, ROSA-guided stereotactic ICH aspiration effectively aspirated more than 50% of hematoma volume (or more than 30 mL for massive hematomas), thereby reducing the residual hemat oma to less than 15 mL. The mean operative time of entire surgical procedure was 1.3 ± 0.3 h, with very little perioperative blood loss and no perioperative com plications. No patients required catheter replacement and all patients' function al status improved."

According to news reporting from Macao, People's Republic of China, by NewsRx journalists, research stated, "In semiconductor manufacturing, multi-spac e process modules (PMs) are adopted in some cluster tools for wafer processing. With multi-space PMs, a PM can have multiple wafers concurrently." Financial supporters for this research include Science And Technology Developmen t Fund (Fdct), Macau Sar. The news editors obtained a quote from the research from Macau University of Sci ence and Technology: "Also, the internal chamber in a PM should rotate to make t he robot able to load/unload a wafer into/from a space in the PM. This means tha t the wafer staying time in PMs is affected by both the rotation operations of t he internal chambers of PMs and the robot tasks. Thus, minimizing the wafer dela y time is quite challenging. In this work, for cluster tools with single-arm rob ots and two-space PMs, efforts are made for wafer delay minimization in scheduli ng the tools. Specifically, a two-wafer backward strategy is presented to operat e the tools in a steady state. Then, the workloads of each processing step and t he robot are analyzed."
