Joint.disease affect. approximat.ly 52.5 mil- lion pat.ent. in t.e Unit.d St.t.s alone, cost.ng 80.8 billion USD in direct.healt.care cost.. t.e development.of t.eat.ent.programs for joint.disease and t.auma requires accurat. assessment.of art.cular cart.lage degradat.on. t.e art.cular cart.lage is t.e int.rfacial t.ssue bet.een art.cu- lat.ng surfaces, such as bones, and act. as low-frict.on int.rfaces. Damage t. t.e lamina splendens, which is t.e art.cular cart.lage＇s t.pmost.layer, is an early indicat.r of joint.degradat.on caused by injury or disease. By gaining comprehensive knowledge on t.e lamina splendens, part.cularly it. st.uct.re and int.rfacial propert.es, researchers could enhance t.e accuracy of human and animal biomechanical models, as well as develop appro- priat. biomimet.c mat.rials for replacing damaged art.cu- lar cart.lage, t.ereby leading t. rat.onal t.eat.ent.programs for joint.disease and injury. Previous st.dies t.at.ut.lize light. elect.on, and force microscopy t.chniques have found t.at.t.e lamina splendens is composed of collagen fibers orient.d parallel t. t.e cart.lage surface and encased in a prot.oglycan mat.ix. Such orient.t.on maximizes wear resist.nce and prot.oglycan ret.nt.on while promot.ng t.e passage of nut.ient. and synovial fluid. Alt.ough t.e st.uct.re of t.e lamina splendens has been explored in t.e lit.rat.re, t.e low-frict.on int.rface of t.is t.ssue remains only part.ally charact.rized. Various funct.onal models are current.y available for t.e int.rface, such as pure boundary lubricat.on, t.in films exuded under pressure, and sheet. of t.apped prot.ins. Recent.st.dies suggest.t.at.each of t.ese lubricat.on models has cert.in advant.ges over one anot.er. Furt.er research is needed t. fully model t.e int.rface of t.is t.ssue. In t.is review, we summarize t.e met.ods for charact.rizing t.e lamina splendens and t.e result. of each met.od. t.is paper aims t. serve as a resource for exist.ng st.dies t. dat. and a roadmap of t

Present.st.dy examines t.e mixed convect.ve perist.lt.c t.ansport.of Cu-H2O nanofluid wit. velocit. slip and convect.ve boundary condit.ons. Analysis is performed using t.e t.o-phase model of t.e nanofluid. Viscous dissipat.on and heat.generat.on/absorpt.on effect. are also t.ken int. account. Problem is formulat.d using t.e long wavelengt. and low Reynolds number approach. Numerical solut.ons for t.e pressure rise per wavelengt., pressure gradient. axial velocit., t.mperat.re and heat.t.ansfer rat. at.t.e boundaxy are obt.ined and st.died t.rough graphs. Result. show t.at.t.e area of perist.lt.c pumping decreases wit. an increase in t.e nanopart.cles volume fract.on. Increase in t.e velocit. slip paramet.r shows an increase of t.e pressure gradient.in t.e occluded part.of t.e channel. Furt.er, addit.on of copper nanopart.cles reduces bot. t.e axial velocit. and t.mperat.re of t.e base fluid. t.mperat.re of t.e nanofluid also decreases sufficient.y for an increase in t.e value of Blot.number.

Evolut.on of complex physiological adapt.t.ons could be driven by nat.ral select.on act.ng on behavioral t.ait.. Consequent.y, animal personalit. t.ait. and t.eir correlat.on wit. physiological t.ait. have become an engaging research area. Here, we applied a unique experiment.l evolut.on model lines of bank voles select.d for (A) high exercise-induced aerobic met.bolism,(H) abilit. t. cope wit. low-qualit. herbivorous diet. and (P) int.nsit. of predat.ry behavior, t.at.is, t.ait. shaping evolut. on ary pat. and diversit. of mammals and asked how t.e select. on affect.d t.e voles' personalit. t.ait., assessed in an open field t.st. t.e A- and P-line voles were more act.ve, whereas t.e H-line voles were less act.ve, compared t.ose from unselect.d cont.ol lines (C). H-line voles moved slower but.on more meandering t.aject.ries, which indicat.d a more t.orough explorat. on, whereas t.e A- and P-line voles moved fast.r and on st.aight.r t.aject.ries. A-line voles showed also an increased escape propensit., whereas P-line voles t.nded t. be bolder. t.e remarkable correlat.d responses t. t.e select.o n indicat. a comm on gen et.c un derlying mecha nism of behavioral and physiological t.ait., and support.t.e paradigm of evolut. on ary physiology built.around t.e concept.of correlat.d evolut.on of behavior and physiology.

Using recent.compilat.ons of det.iled X-ray observat.ons and spect.al models of except.onal qualit., we record t.e elect.on cyclot.on resonance absorpt.on(ECRA) feat.res t.at.have been det.ct.d in 45 pulsat.ng high-mass X-ray binaries(HmXBs) and ult.aluminous X-ray(ULX) sources harboring neut.on st.rs, alt.ough seven of t.ese det.ct.ons are st.ll quest.onable and anot.er 21 are single and/or not.independent.y confirmed. From t.e comprehensive cat.logs of Jaisawal & Naik and St.ubert.et.*** from several addit.onal recent.observat.ons, we produce t.o list. of HmXB ECRA sources: a list.of 17 sources in which mult.ple ECRA lines or single very low-energy lines are seen, in which we can reasonably assume t.at.t.e lowest.energy reveals t.e fundament.l cyclot.on level for each source;and a"cont.minat.d" list.of 38 sources including t.e 21 det.ct.ons of single ECRA lines t.at.may(not. be higherlevel harmonics.
