Multivitamins were widely used health supplements that replenished essential nutrients in the human body. Despite their popularity， the impact of multivitamins on the cognitive function of older adults remained unclear and contentious. This study offered a comprehensive review and meta-analysis of research published until June 2024， analyzing the effects of multivitamins on various cognitive functions in individuals aged 65 and older. We included ten randomized controlled trials encompassing 13，600 participants from multiple databases. These studies evaluated the impact of multivitamins on reasoning， memory， learning， visual perception， idea production， cognitive speed， psychomotor abilities， and higher cognitive functions. Our meta-analysis revealed that multivitamins significantly enhanced delayed free recall (SMD = 0.09， 95% Ci: [0.05， 0.13]， p ial effects on immediate free recall (SMD = 0.85， 95% Ci: [-0.18， 1.90]， p = 0.11)， idea production (SMD = -0.00， 95% Ci: [-0.04， 0.03]， p = 0.86)， or cognitive speed (SMD=0.34， 95% Ci: [-0.07， 0.74]， p = 0.11). Thus， while multivitamins facilitated delayed free recall， they did not significantly improve other cognitive functions in older adults.

时间与金钱是两种重要的资源类型,人们在绿色消费的过程中不可避免地会受到这两种资源对认知思维和决策行为的影响。然而,目前对于资源类型影响绿色消费行为的具体机制仍不明确。本研究将时间与金钱引发的认知差异引入绿色消费,一方面,基于解释水平理论与人类价值观,分析了时间资源如何促进绿色消费,以及金钱资源如何抑制绿色消费。另一方面,分别从个体、企业以及产品层面出发,结合实验法探究时间与金钱资源影响绿色消费的边界条件,并引入情绪响应水平、环保自我担当以及感知产品有效性作为中介变量,构建资源类型影响绿色消费的理论模型。研究结论将有助于发挥时间与金钱资源在促进绿色消费过程中的积极作用,同时也为企业利用资源线索引导绿色消费提供了新的思路。

The Japanese movie“0.5mm”connects the life clips between the nursing-care helper Sawa and several old people in the form of a road movie,highlighting many thought-provoking social problems,and revealing how the elements of emotional abuse hidden between the old people and their relatives and friends affect people’s dignity and decency,and at the same time trying to offset the persecution from the emotional abuse with the warm kindness between the elderly and the care *** film’s implicit description of emotional abuse and explicit display of good deeds are blended in the quiet and mysterious narrative character,achieving the effect of synchronizing the artistic narrative rhythm with the flow of life,reflecting the unique aesthetic characteristics of Japanese films.

The stable switching phenomenon of a diffusion mussel-algae system with two delays and half saturation constant is studied. The stability of positive equilibrium and the existence of Hopf bifurcation on two-delay plane are investigated by calculating the stability switching curves. The normal form on the central manifold near Hopf bifurcation point is also derived. it can find that two different delays can induce the stable switches which cannot occur with the same delays. Through numerical simulations, the region of complete stability of system increases with the increase of half-saturation constant, indicating that the half-saturation constant contributes to the stability of system. in addition, double Hopf bifurcations may occur due to the intersection of bifurcation curves. These results show that two different delay and half-saturation constant have important effects on the system. The numerical simulation results validate the correctness of the theoretical analyses.

This paper aims to construct a two-grid scheme of fully discretized expanded mixed finite element methods for optimal control problems governed by parabolic integro-differential equations and discuss a priori error estimates. The state variables and co-state variables are discretized by the lowest order Raviart-Thomas mixed finite element, and the control variable is approximated by piecewise constant functions. The time derivative is discretized by the backward Euler method. Firstly, we define some new mixed elliptic projections and prove the corresponding error estimates which play an important role in subsequent convergence ***, we derive a priori error estimates for all variables. Thirdly, we present a two-grid scheme and analyze its convergence. in the two-grid scheme, the solution of the parabolic optimal control problem on a fine grid is reduced to the solution of the parabolic optimal control problem on a much coarser grid and the solution of a decoupled linear algebraic system on the fine grid and the resulting solution still maintains an asymptotically optimal accuracy. At last, a numerical example is presented to verify the theoretical results.

A numerical study based on a two-dimensional two-phase SPH(Smoothed Particle Hydrodynamics) model to analyze the action of water waves on open-type sea access roads is presented. The study is a continuation of the analyses presented by chen et al.(2022), in which the sea access roads are semi-immersed. in this new configuration, the sea access roads are placed above the still water level, therefore the presence of the air phase becomes a relevant issue in the determination of the wave forces acting on the structures. indeed, the comparison of wave forces on the open-type sea access roads obtained from the single and two-phase SPH models with the experimental results shows that the latter are in much better agreement. So in the numerical simulations, a two-phase δ-SPH model is adopted to investigate the dynamical problems. Based on the numerical results, the maximum horizontal and uplifting wave forces acting on the sea access roads are analyzed by considering different wave conditions and geometries of the structures. in particular, the presence of the girder is analyzed and the differences in the wave forces due to the air cushion effects which are created below the structure are highlighted.
