Abstract Flow boiling in open microchannels offers highly efficient heat transfer performance and has attracted increasing attention in the fields of heat transfer and thermal management of electronic devices in recent years. However, the continuous rise in power density of electronic components imposes more stringent requirements on the heat transfer capability of microchannel flow boiling. HFE-7100, a dielectric coolant with favorable thermophysical properties, has become a focal point of research for enhancing flow boiling performance in open microchannels. The flow boiling heat transfer performance of HFE-7100 was investigated in this study by fabricating micro-nano composite structures… More >

Abstract Introduction: Partial gland ablation (PGA) using high intensity focal ultrasound (HIFU) is an alternative to active surveillance for low to intermediate risk localized prostate cancer. This pilot study assessed quality of life (QoL) outcomes during the implementation of PGA HIFU at our institution.
Materials and methods: We prospectively enrolled 25 men with a diagnosis of localized low/intermediate risk prostate cancer who elected to undergo PGA-HIFU in a pilot study at our institution between 2013 and 2016. Patients underwent pre-treatment mpMRI and transrectal ultrasound-guided biopsies. The primary endpoints were impact on patient-reported functional outcomes (erectile, urinary function, QoL)… More >

Abstract Standard treatment approaches for localized prostate cancer remain limited to active surveillance, radiotherapy, and radical prostatectomy. We present a case of transition zone prostate cancer that was treated with holmium laser enucleation of the prostate, a procedure that is normally reserved for the management of benign prostatic hyperplasia.

Abstract Introduction: Local disease recurrence following focal therapy (FT) for prostate cancer may be due to failure to eradicate focal disease or development of disease in the untreated prostate (in- and out-of-field recurrences). Several studies suggest in-field contrast enhancement (CE) on post treatment multi-parametric (mp) MRI between 6-12 months following FT indicates residual disease. The present study assesses the incidence and oncologic implications of early CE observed following primary partial gland cryoablation (PPGCA).
Material and methods: The surveillance protocol for men enrolled in our prospective outcomes study following PPGCA included mpMRI at 6-12 months, 2 years, 3.5 years,… More >

Abstract Surgical ablation (SA) has become an essential rhythm-control strategy for managing tachyarrhythmias in patients with congenital heart disease. Atrial tachyarrhythmias, such as atrial flutter and atrial fibrillation, are prevalent in congenital heart disease, affecting up to 50% of patients, and pose significant risks, including increased morbidity and mortality. Ventricular tachyarrhythmias, though less common, can lead to sudden cardiac death, particularly in conditions like Tetralogy of Fallot. Prior studies suggested that SA for tachyarrhythmias in patients with congenital heart disease offers significant benefits, including superior long-term rhythm control compared to catheter ablation (CA). Atrial tachyarrhythmia burden… More > Graphic Abstract

Abstract Brain tumors pose a significant threat to human lives and have gained increasing attention as the tenth leading cause of global mortality. This study addresses the pressing issue of brain tumor classification using Magnetic resonance imaging (MRI). It focuses on distinguishing between Low-Grade Gliomas (LGG) and High-Grade Gliomas (HGG). LGGs are benign and typically manageable with surgical resection, while HGGs are malignant and more aggressive. The research introduces an innovative custom convolutional neural network (CNN) model, Glioma-CNN. GliomaCNN stands out as a lightweight CNN model compared to its predecessors. The research utilized the BraTS 2020 More >

Abstract Introduction: A common indication for benign prostate hyperplasia (BPH) therapies is failure to improve with medical therapy. However, pivotal Federal Drug Administration (FDA) registered randomized clinical trials (RCTs) for minimally invasive surgical therapies (MISTs) are designed to be compared to either sham or placebo while off medical therapy at baseline, and as an alternative to medical therapy. There are few if any RCTs reporting the MISTS efficacy in patients with true medical therapy failure. We report on the efficacy of robotic water jet ablation therapy (RWT) and TURP in patients who have failed to improve with… More >

Abstract The ablation of ultra-high-temperature ceramics (UTHCs) is a complex physicochemical process including mechanical behavior, temperature effect, and chemical reactions. In order to realize the structural optimization and functional design of ultra-high temperature ceramics, a coupled thermo-chemomechanical bond-based peridynamics (PD) model is proposed based on the ZrB₂ ceramics oxidation kinetics model and coupled thermomechanical bond-based peridynamics. Compared with the traditional coupled thermo-mechanical model, the proposed model considers the influence of chemical reaction process on the ablation resistance of ceramic materials. In order to verify the reliability of the proposed model, the thermomechanical coupling model, damage model and… More >

Abstract The reactor pressure vessels (RPV), a typical kind of axisymmetric structures, usually serve under high temperature and pressure conditions. The numerical analysis of the mechanical behaviors of these structures plays a dominant role for their structural design, advanced manufacture and safety assessment in practical engineering applications[1-2]. However, the extremely conditions bring great challenges for the numerical analysis of structures undergo ablation, plastic, damage and even fracture during an accident[3]. Based on the superior performance of peridynamics model in predicting fracture behaviors [4-7], a coupled axisymmetric non-ordinary state-based peridynamics (CA-NOSB-PD) model is proposed in this work… More >
