this paper examines the transport analysis, including both heat transfer and mass transfer, in hybrid nanofluid flow containing gyrotactic microorganisms towards a curved oscillatory surface. the influence of magnetic fields is also inspected in terms of their physical characteristics. to depict the phenomena of transport, modified versions of both Fick's and Fourier's laws are used. Additionally, the characteristics of both heterogeneous and homogeneous chemical reactions are also incorporated. Utilizing a curvilinear coordinate system, the flow problem is formulated as partial differential equations(PDEs)for momentum, concentration, microorganism field, and energy. An analytical solution to the obtained flow equations is achieved utilizing the homotopy analysis method(HAM).the effects of significant flow parameters on the pressure and microorganism fields, velocity, oscillation velocity, concentration, and temperature distributions are shown via graphs. Furthermore, the variations in skin friction, mass transfer rate, heat transfer rate, and local motile number due to different involved parameters are presented in tables and are analyzed in detail. Graphical results indicate that the curves of velocity and temperature fields are enhanced as the values of the solid volume fraction variables *** is also verified that the concentration rate field decreases as the values of the homogeneous reaction strength parameter and the radius of curvature parameter increase, and it increases with the Schmidt number and the heterogeneous reaction strength *** outcomes show a favorable response of the motile number to advanced values of the Peclet number, the Schmidt number, the microorganism difference parameter, and the bio-convective Lewis number.

the three-phase-lag(tPL) heat conduction model is an accurate representation of the actual heat transfer process. It would be interesting to investigate how the tPL model affects the thermal fracture behavior when there are defects existing in the medium. this paper aims to analyze the thermoelastic responses of two collinear cracks within a functionally graded half-space under thermal loadings by means of the tPL model. the thermoelastic problem is transformed into a series of singular integral equations using the integral transformation methods. the transient temperature and stress intensity factors(SIFs) are obtained through the application of Chebyshev *** effects of crack spacing and non-homogeneous parameters on the transient thermoelastic responses are presented, and the results of the tPL model are compared with those of the Fourier model, Cattaneo and Vernotte(CV) model, and dual-phase-lag(DPL)model. It is shown that crack spacing and non-homogeneous parameters have important effects on the thermoelastic responses, and the fluctuation phenomenon under the tPL model is the most pronounced due to the existence of the thermal displacement lag term.

A scheme based on irregular V-shaped silicon nanoantennas is proposed to optimize transverse unidirectional scattering under plane wave irradiation. traditional methods of designing regular shapes offer fewer parameters and higher search efficiency. However, due to the limitations of regular shapes, it is challenging to meet high-precision design requirements. Irregular shape design allows for a broader range of adjustments, but the complexity of shape parameters leads to lower search efficiency and a higher likelihood of converging to local optima.

to learn the subgroup structure generated by multidimensional interaction, we propose a novel multiview subgroup integration technique based on tensor decomposition. Compared to the traditional subgroup analysis that can only handle single-view heterogeneity, our proposed method achieves a greater level of homogeneity within the subgroups, leading to enhanced interpretability and predictive power. For computational readiness of the proposed method, we build an algorithm that incorporates pairwise shrinkage-encouraging penalties and ADMM techniques. theoretically, we establish the asymptotic consistency and normality of the proposed estimators. Extensive simulation studies and real data analysis demonstrate that our proposal outperforms other methods in terms of prediction accuracy and grouping consistency. In addition, the analysis based on the proposed method indicates that intergenerational care significantly increases the risk of chronic diseases associated with diet and fatigue in all provinces while only reducing the risk of emotion-related chronic diseases in the eastern coastal and central regions of China.

经典抗焦虑抑郁药物-度洛西汀为带状疱疹后神经痛(postherpetic neuralgia,PHN)的一线治疗药物。本研究首次提出在带状疱疹出疱急性期预防性口服度洛西汀有望预防PHN的发生,纳入疼痛VAS评分≥4、带状疱疹出疱72 h内的750例病人,随机分为对照组和度洛西汀组。对照组接受常规临床治疗,度洛西汀组在常规治疗基础上口服度洛西汀。主要结局指标为12周时PHN的发生率。次要结局指标包括3、4、8周VAS评分>0的人数,以及4、8、12周VAS评分≥3的人数、生活质量评分、病人总体变化评分、睡眠质量评分等。结果表明,度洛西汀组的PHN发生率与对照组相比无显著差异,度洛西汀组第3、4、8周VAS评分>0的人数,以及4、8和12周VAS评分≥3的人数显著少于对照组。度洛西汀组病人的生活质量评分、病人总体变化评分、睡眠质量评分均显著优于对照组。虽然本研究为阴性结果,但预防性口服度洛西汀仍可以避免5.9%的带状疱疹病人发展成为PHN,因此具有一定的临床意义。
