The influence of grain boundaries on heat transfer through polycrystalline alumina has been investigated between 20° and 500°C. thermal conductivities small‐grained porous ceramics large‐grained dense have measured using the laser‐flash technique. Two methods developed to assess average resistance a boundary. first method is based comparison room‐temperature for that various sizes. This yields value 0.9 × 10 −8 m 2 ·K·W −1 . second method, particularly suitable ceramics, extrapolation...

We prove that mutation of cluster-tilting objects in triangulated 2-Calabi-Yau categories is closely connected with quivers potentials. This gives a close connection between 2-CY-tilted algebras and Jacobian associated show cluster-tilted are also they determined by their quivers. There similar results when dealing tilting modules over 3-CY algebras. The nearly Morita equivalence for shown to hold the finite length

PURPOSE Although immune checkpoint inhibitors (ICIs) have improved outcomes in certain patients with cancer, they can also cause life-threatening immunotoxicities. Predicting immunotoxicity risks alongside response could provide a personalized risk-benefit profile, inform therapeutic decision making, and improve clinical trial cohort selection. We aimed to build machine learning (ML) framework using routine electronic health record (EHR) data predict hepatitis, colitis, pneumonitis, 1-year...

The authors have assembled a compilation of exposure rate constants, ƒ-factors, and lead shielding thicknesses for more than 1,100 radionuclides described in ICRP Publication 107. Physical data were taken from well established reference sources mass-energy absorption coefficients air, attenuation coefficients, buildup factors other variables.The agreed favorably the most part with those investigators; thus this provides an up-to-date sizeable database these data, which are interest to many...

Abstract Peatlands contain a significant fraction of global soil carbon, but how these reservoirs will respond to the changing climate is still relatively unknown. A picture variations in peat organic matter chemistry aid our ability gauge peatland response climate. The goal this research test hypotheses that (a) carbohydrate content, an indicator reactivity, increase with latitude and decrease mean annual temperatures, (b) while aromatic recalcitrance, vary inversely, (c) elevation have...

Primary barriers to application of immune checkpoint inhibitor (ICI) therapy for cancer include severe side effects (such as potentially life threatening pneumonitis [PN]), which can cause the discontinuation treatment. Predicting patients may develop PN while on ICI would improve both safety and potential efficacy because treatments could be safely administered longer or discontinued before toxicity. Starting from a cohort 3,351 with who received previous at Vanderbilt University Medical...

Compressive sensing (CS) has been shown to enable dramatic acceleration of MRI acquisition in some applications. Being an iterative reconstruction technique, CS reconstructions can be more time-consuming than traditional inverse Fourier reconstruction. We have accelerated our by factors up 27 using a split Bregman solver combined with graphics processing unit (GPU) computing platform. The increases speed we find are similar those measure for matrix multiplication on this platform, suggesting...

Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) involves the acquisition of images before, during and after injection a agent. In order to perform quantitative modeling on resulting signal intensity time course, data must be acquired rapidly, which compromises spatial resolution, noise and/or field view. One approach that may allow for gains in temporal or resolution an individual image is use compressed sensing (CS) MRI. this study, we demonstrate accuracy extracted...

Background Computed tomography (CT) and spirometry are the current standard methods for assessing lung anatomy pulmonary ventilation, respectively. However, CT provides limited ventilation information only global measures of ventilation. Thus, a method that can enable simultaneous examination is clinical interest.

Introduction Benign and malignant myxoid soft tissue tumors have shared clinical, imaging, histologic features that can make diagnosis challenging. The purpose of this study is comparison the diagnostic performance a radiomic based machine learning (ML) model to musculoskeletal radiologists. Methods Manual segmentation 90 (45 myxomas 45 myxofibrosarcomas) was performed on axial T1, T2FS or STIR magnetic resonance imaging sequences. Eighty-seven from each modality were extracted. Five ML...

Differentiating benign and malignant myxoid soft-tissue tumors preoperatively can be challenging due to shared clinical, imaging, histologic features. Biopsy specimens are frequently described as "low-grade neoplasms" without or classification (ie, indeterminate). Our purpose is evaluate the prevalence prognosis of with an indeterminate diagnosis before resection. A retrospective review identified 439 patients a musculoskeletal tumor confirmed on final resection pathology. result (benign,...
