The purpose of this article is to research the existence of solutions for fractional periodic boundary value problems with p(t)-Laplacian operator. In this regard, the article needs to establish a continuation theorem corresponding to the above problem. By applying the continuation theorem, a new existence result for the problem is obtained, which enriches existing literature. In addition, we provide an example to verify the main result.

Using the spectral energy density method, we predict the phonon scattering mean lifetimes of polycrystalline graphene (PC-G) having polycrystallinity only along the -axis with seven different misorientation (tilt) angles at room temperature. Contrary to other studies on PC-G samples, our results indicate a strong dependence of the thermal conductivity (TC) on the tilt angles which we attribute to careful preparation of our grain boundaries-based samples without introducing any local strains and ensuring periodic boundary conditions for the supercells along the and axes. We also show that the square of the group velocity components along and axes and the phonon lifetimes are uncorrelated and the phonon density of states are almost the same for all samples with different tilt angles.

This paper presents the preparation of the parental experimental alloy, featuring a standard composition of TiYZrFeNiMn, via the vacuum induction melting technique. Subsequently, the TiYZrFeNiMn alloy, with an addition of 2 wt% Ni, underwent mechanical ball milling to yield a TiFe-based composite for experimental purposes. The results of the experimental tests indicate that the composite alloy's phase composition comprises the TiFe primary phase, with a minor quantity of ZrMn phase segregated on the surface of the primary TiFe phase, as well as Ni phase.

Gas-water distribution is significant in the determination of hydrocarbon accumulation mechanisms in gas reservoirs, especially for the exploitation of tight sandstone reservoirs. One of such examples are the gas reservoirs in the Yishan Slope in China, where the internal relationship between gas-water distribution is poorly understood. The pattern and controlling factors for gas-water distribution in tight sandstones gas reservoirs in the Yishan Slope have been examined from macro (such as sedimentary and anticlinal structures) and micro (such as pore throat size, heterogeneity) perspectives, using data from rock eval pyrolysis, sedimentary structure, sediment diagenesis, gas migration, mercury injection experiments, and well logs.

Introduction: Mucinous Cystadenocarcinoma (MCA) of the breast remains a relatively rare condition, and to date, there is no systematic summary of its imaging manifestations. Therefore, this report presents a detailed account of the diagnosis and treatment of mucinous cystadenocarcinoma in a 40-year-old woman, with a particular focus on imaging findings. Additionally, we conducted a comprehensive literature review on this disease and summarized its key imaging features.

Transcranial neurosurgery assisted by endoscopy and intraoperative ultrasound (IOUS) has become an effective approach for real-time visualization and guidance during tumor resection. This study explores the application of these techniques in falcine meningioma (FM) resection, assessing their feasibility and safety. Eleven FM patients underwent transcranial endoscopic resection with IOUS assistance.
