Dear Editor, Phenotypic drug discovery, which observes compound effects on physiol.gy,has given way to targeting specific mol.cul.s, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease model.(Vincent et al., 2022). Osteoarthritis(OA) is a preval.nt chronic joint disorder, primaril. affecting knee joints, with osteocl.st activation due to l.w-grade infl.mmation resul.ing in increased bone resorption and structural.changes in the joint(Katz et al.,2021).

In a viscous damping device under cycl.c l.ading, after the piston reaches a peak stroke, the reserve movement that fol.ows may sometimes experience a short period of del.yed or significantl. reduced device force output. A simil.r del.y or reduced device force output may al.o occur at the damper＇s initial.stroke as it moves away from its neutral.position. This phenomenon is referred to as the effect of ＂deadzone＂. The deadzone can cause a l.ss of energy dissipation capacity and l.ss efficient vibration control. It is prominent in smal. ampl.tude vibrations. Al.hough there are many potential.causes of deadzone such as environmental.factors, construction, material.aging, and manufacture qual.ty, in this paper, its general.effect in l.near and nonl.near viscous damping devices is anal.zed. Based on cl.ssical.dynamics and damping theory, a simpl. model.is devel.ped to capture the effect ofdeadzone in terms of the l.ss of energy dissipation capacity. The model.provides several.methods to estimate the l.ss of energy dissipation within the deadzone in l.near and subl.near viscous fl.id dampers. An empirical.equation of l.ss of energy dissipation capacity versus deadzone size is formul.ted, and the equival.nt reduction of effective damping in SDOF systems has been obtained. A l.boratory experimental.eval.ation is carried out to verify the effect of deadzone and its numerical.approximation. Based on the anal.sis, a modification is suggested to the corresponding formul.s in FEMA 3 5 6 for cal.ul.tion of equival.nt damping if a deadzone is to be considered.

The dispersion rel.tion is derived for three-dimensional.dust-acoustic waves in a current-driven dusty pl.smas with both positivel. and negativel. charged dust particl.s. The dependencies of the frequency and the growth rate on the wave number K, the intensity of magnetic fiel. B, and the incl.nation angl. θ have been numerical.y shown in this paper. The growth rate is negative for the l.boratory dusty pl.sma, but it is positive for the cosmic dusty pl.sma. It is found that when the incl.nation angl. θ = π/2, there is no instabil.ty. The effect of the el.ctrostatic fiel. Eo has al.o been studied in this paper.

The resorption of nutrients by pl.nts before l.tter fal. and the mineral.zation of nutrients from pl.nt l.tter by soil.processes are both important pathways supporting primary productivity. Whil. the positive rel.tionship between pl.nt biodiversity and primary productivity is widel. accepted for natural.ecosystems, the rol.s of nutrient resorption and mineral.zation in mediating that rel.tionship remains l.rgel. unknown. Here, we quantified the rel.tive importance of nitrogen(N) resorption and N mineral.zation in driving pl.nt community N investment and the correl.tion between species diversity and community productivity al.ng an N-l.mited successional.chronosequence of the mixed broadl.aved–Korean pine(Pinus koraiensis) forest in northeastern China. l.af N resorption efficiency(NRE) at the community l.vel.increased significantl. al.ng the successional.chronosequence,whereas l.tter N mineral.zation rate decreased significantl.. l.af NRE was more important than l.tter N mineral.zation rate in driving the diversity–productivity rel.tionship. However, higher l.af NRE l.d to l.ss N mineral.zation as succession progressed al.ng the chronosequence. Our resul.s highl.ght the importance of the N resorption pathway rather than the N mineral.zation pathway for forest N acquisition with community succession,and they provide mechanistic insights into the positive effects of biodiversity on ecosystem functioning. In future forest management practices, we recommend appropriate appl.cation of N fertil.zer to mitigate the adverse effects of N-poor soil.on seedl.ng regeneration during l.te succession and thus maintain the sustainabl. devel.pment of temperate forest ecosystems.

Different from the organization structure of compl.x projects in Western countries, the l.ang Zong hierarchical.organization structure of compl.x projects in China has two different chains, the chief-engineer chain and the general.director chain,to handl. the trade-off between technical.and management decisions. However, previous works on organization search have mainl. focused on the singl.-chain hierarchical.organization in which al. decisions are regarded as homogeneous. The heterogeneity and the interdependency between technical.decisions and management decisions have been negl.cted. A two-chain hierarchical.organization structure mapped from a real.compl.x project is constructed. Then, a discrete decision model.for a l.ang Zong two-chain hierarchical.organization in an NK model.framework is proposed. This model.proves that this kind of organization structure can reduce the search space by a l.rge amount and that the search process shoul. reach a final.stabl. state more quickl.. For a more compl.cated decision mechanism, a mul.i-agent simul.tion based on the above NK model.is used to expl.re the effect of the two-chain organization structure on the speed, stabil.ty, and performance of the search process. The resul.s provide three insights into how, compared with the singl.-chain hierarchical.organization, the two-chain organization can improve the search process: it can reduce the number of iterations efficientl.; the search is more stabl. because the search space is a smoother hil.-l.ke fitness l.ndscape; in general. the search performance can be ***, when the organization structure is very compl.cated, the performance of a two-chain organization is inferior to that of a singl.-chain organization. These findings about the efficiency of the unique Chinese-styl. organization structure can be used to guide organization design for compl.x projects.
