Objective: To build and validate a periprostatic fat magnetic resonance imaging (MRI) based radiomics nomogram for prediction of biochemical recurrence-free survival (bRFS) of patients with non-metastatic prostate cancer (PCa) receiving radical prostatectomy (RP).

Methods: A retrospective study was conducted on 356 patients with non-metastatic PCa who underwent preoperative mpMRI followed by RP treatment at our institution. Radiomic features were extracted from both intratumoral region and the periprostatic fat region, which were segmented on images obtained through T2-weighted imaging (T2WI) and apparent-diffusion coefficient (ADC) imaging.

Quantum mechanical effects in plasmonic sub-nanometer cavities formed by a tip and substrate structure.

Enhancing local field intensity through light field compression is one of the core issues in surface plasmon-enhanced spectroscopy. The theoretical framework for the nanostructure composed of a tip and a substrate has predominantly relied on classical electromagnetic models, ignoring the electron tunneling effect. In this paper, we investigate the plasmonic near-field characteristics in the sub-nanometer cavity formed by the tip and the substrate using a quantum-corrected model.

Inhibitory DNA Aptamer Tools against SOCS3-gp130 Interactions.

The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway plays a crucial role in transmembrane signal transduction, enabling cells to communicate with the extracellular environment, which requires precise regulation to prevent abnormal signaling outcomes. Within this complex pathway, suppressor of cytokine signaling 3 (SOCS3) acts as a pivotal negative regulator via binding to cytokine receptors. However, our understanding of the regulatory mechanisms governing SOCS3 interactions has been limited by the lack of suitable chemical probes.

High sensitivity strain and refractive index MZI-SPR sensing based on dual fiber winding structure.

Fiber strain and refractive index dual parameter sensor have enormous potential in the field of underwater structural health monitoring. This article proposes a strain and refractive index highly sensitive MZI-SPR composite sensor based on a dual fiber winding structure. By twisting single-mode fiber and multi-mode fiber, the two fibers are wound together to produce regular multiple bends.

Two distinct current systems in the ionosphere of Mars.

When the solar wind interacts with the ionosphere of an unmagnetized planet, it induces currents that form an induced magnetosphere. These currents and their associated magnetic fields play a pivotal role in controlling the movement of charged particles, which is essential for understanding the escape of planetary ions. Unlike the well-documented magnetospheric current systems, the ionospheric current systems driven by solar wind and atmospheric neutral winds have not been quantitatively observed, which constrains the quantification of energy transfer from stars to these planets.

Molecular diffusion in aqueous methanol solutions: The combined influence of hydrogen bonding and hydrophobic ends.

Although the nonmonotonic variation in the diffusion coefficients of alcohol and water with changing alcohol concentrations in aqueous solutions has been reported for many years, the underlying physical mechanisms remain unclear. Using molecular dynamics simulations, we investigated the molecular diffusion mechanisms in aqueous methanol solutions. Our findings reveal that the molecular diffusion is co-influenced by hydrogen bonding and the hydrophobic ends of methanol molecules.

Empowering the Sustainable Development of High-End Alloys via Interpretive Machine Learning.

The extensive use of scarce, expensive, and toxic elements in high-performance metal alloys restricts their sustainable development. Here we propose a novel alternative alloying-element design strategy that combines physicochemical-factor screening, a "black-box" interpretative method based on SHapley Additive exPlanation analysis, and sensitivity analyses of elemental influence. A "white-box" model of alloy compositions and properties is therefore established that enables the rational selection of abundant elements and the efficient designs of alloys with substitution for scarce alloying elements.

Study on the imbibition production mechanism and main controlling factors of low-permeability reservoir.

With high water cuts and high permeability reservoirs entering the middle and late stage, many old oil fields in China are facing the dilemma of oil and gas resource exhaustion, while low-permeability reservoir resources remain very rich. As an oil recovery technology, imbibition displacement plays an important role in the exploitation of low-permeability reservoirs and prolongs the production cycle of old oil fields. Based on the imbibition kinetic equation, the mechanism and process of oil displacement in imbibition recovery are explained in this paper.
