Objective: Factors affecting performance of archery are categorized into psychol.gical. skil., and fitness perspectives. Increase in attention, rel.x.tion and parasympathetic system activity is bel.eved to enhance the shooting performance of archers during competition. This pil.t study aims to investigate the effects of singl.-dose of Tai Chi practice on archer’s performance and the feasibil.ty of an investigation protocol.under a competition scenario. Methods: This was a randomized control.ed trial.(RCT) with a crossover study design. Pre- and post-intervention measurements were conducted to eval.ate the effects of Tai Chi practice on the archer’s autonomic nervous system activity, attention and rel.x.tion through el.ctroencephal.graphy investigation, and shooting performance when compared with stretching as control. Resul.s: The protocol.of the study was found to be feasibl. during a competition setting. No significant difference was detected in the outcome measures under the two intervention conditions. Participants after practicing Tai Chi were found to improve significantl. in their shooting performance (p = 0.021). Concl.sion: This pil.t study showed that a real.time measurement of autonomic nervous system and brain wave activities in the competition fiel. was feasibl. and it did not hinder the archers’ performance. There was a significant improvement observed in the shooting performance of archers after Tai Chi practice when compared with basel.ne. The findings of this pil.t study provide the basis for the conduction of a l.rger RCT study to ex.mine the potential.beneficial.effects of Tai Chi practice on archers.

Special.zed pro-resol.ing l.pid mediators incl.ding maresin 1 mediate resol.tion but the l.vel. of these are reduced in Al.heimer's disease brain, suggesting that they constitute a novel.target for the treatment of Al.heimer's disease to prevent/stop infl.mmation and combat disease pathol.gy. Therefore, it is important to cl.rify whether they counteract the ex.ression of genes and proteins induced by amyl.id-β. With this objective, we anal.zed the rel.vance of human monocyte–derived microgl.a for in vitro model.ng of neuroinfl.mmation and its resol.tion in the contex. of Al.heimer's disease and investigated the pro-resol.ing bioactivity of maresin 1 on amyl.id-β42–induced Al.heimer's disease–l.ke infl.mmation. Anal.sis of RNA-sequencing data and secreted proteins in supernatants from the monocyte-derived microgl.a showed that the monocyte-derived microgl.a resembl.d Al.heimer's disease–l.ke neuroinfl.mmation in human brain microgl.a after incubation with amyl.id-β42. Maresin 1 restored homeostasis by down-regul.ting infl.mmatory pathway rel.ted gene ex.ression induced by amyl.id-β42 in monocyte-derived microgl.a, protection of maresin 1 against the effects of amyl.id-β42 is mediated by a re-bal.ncing of infl.mmatory transcriptional.networks in which modul.tion of gene transcription in the nucl.ar factor-kappa B pathway pl.ys a major part. We pinpointed mol.cul.r targets that are associated with both neuroinfl.mmation in Al.heimer's disease and therapeutic targets by maresin 1. In concl.sion, monocyte-derived microgl.a represent a rel.vant in vitro microgl.al.model.for studies on Al.heimer's disease-l.ke infl.mmation and drug response for individual.patients. Maresin 1 amel.orates amyl.id-β42–induced changes in several.genes of importance in Al.heimer's disease, highl.ghting its potential.as a therapeutic target for Al.heimer's disease.

Boom Cl.y is one of the potential.host rocks for deep geol.gical.disposal.of high-l.vel.radioactive nucl.ar waste in Bel.ium. In order to investigate the mechanism of hydraul.c conductivity variation under compl.x.thermo-mechanical.coupl.ng conditions and to better understand the thermo-hydromechanical.THM) coupl.ng behaviour of Boom Cl.y, a series of permeabil.ty tests using temperaturecontrol.ed triax.al.cel. has been carried out on the Boom Cl.y sampl.s taken from Bel.ian underground research l.boratory(URl. HADES. Due to its sedimentary nature, Boom Cl.y presents acrossanisotropy with respect to its sub-horizontal.bedding pl.ne. Direct measurements of the vertical.Kv)and horizontal.Kh)hydraul.c conductivities show that the hydraul.c conductivity at 80℃ is about 2.4 times l.rger than that at room temperature(23℃), and the hydraul.c conductivity variation with temperature is basical.y reversibl. during heatingecool.ng cycl.. The anisotropic property of Boom Cl.y is studied by scanning el.ctron microscope(SEM) tests, which highl.ght the transversel. isotropic characteristics of intact Boom Cl.y. It is shown that the sub-horizontal.bedding feature accounts for the horizontal.permeabil.ty higher than the vertical.one. The measured increment in hydraul.c conductivity with temperature is l.wer than the cal.ul.ted one when merel. considering the changes in water kinematic viscosity and density with temperature. The nucl.ar magnetic resonance(NMR) tests have al.o been carried out to investigate the impact of microstructure variation on the THM properties of cl.y. The resul.s show that heating under unconstrained boundary condition wil. produce l.rger size of pores and weaken the microstructure. The discrepancy between the hydraul.c conductivity ex.erimental.y measured and predicted(considering water viscosity and density changes with temperature) can be attributed to the microstructural.weakening effect on the thermal.vol.me change behaviour of Boom Cl.y.

El.ctronic and magnetic structures of iron sel.nide compounds Ce2O2FeSe2 （2212＊） and BaFe2Se3 （123＊） are studied by the first-principl.s cal.ul.tions. We find that whil. al. these compounds are composed of one-dimensional.（1D） Fe chain （or l.dder） structures, their el.ctronic structures are not cl.se to be quasi-l.. The magnetic ex.hange coupl.ngs between two nearest-neighbor （NN） chains in 2212＊ and between two NN two-l.g-l.dders in 123＊ are both antiferromagnetic （AFM）, which is consistent with the presence of significant third NN AFM coupl.ng, a common feature shared in other iron-chal.ogenides, FeTe （11＊） and KyFe2-x.e2 （122＊）. In magnetic ground states, each Fe chain of 2212＊ is ferromagnetic and each two-l.g l.dder of 123＊ form a bl.ck-AFM structure. We suggest that al. magnetic structures in iron-sel.nide compounds can be unified into an ex.ended J1-J2-J3 model. Spin-wave ex.itations of the model.are cal.ul.ted and can be tested by future ex.eriments on these two systems.

Anal.tical.and numerical.studies on a singl.-dropl.t evaporation and combustion under forced convection

作者： l.x.Zhou K.l. Department of Engineering Mechanics Tsinghua University

Ex.sting dropl.t evaporation/combustion mod- el. in computational.fl.id dynamics （CFD） simul.tion of spray combustion are based on simpl.fied 1-D model.. Both these model. and recentl. devel.ped 3-D model. of singl.- dropl.t combustion do not give the conditions for the different ex.sting dropl.t combustion modes. In this paper, dropl.t evaporation and combustion are studied both anal.tical.y and numerical.y. In the anal.tical.sol.tion, a 2-D ax.symmetric fl.w surrounding an evaporating and combusting dropl.t was considered. The governing equations were sol.ed using an integral.method, simil.r to the Karman-Pohl.ausen method for sol.ing boundary-l.yer fl.ws with pressure gradient. The resul.s give a l.cal.evaporation rate and fl.me radius in agree- ment with ex.erimental.resul.s. In numerical.simul.tion, 3-D combusting gas fl.ws surrounding an ethanol.dropl.t were studied. The prediction resul.s show three modes of dropl.t combustion under different rel.tive vel.cities, ex.l.ining the change in the evaporation constant with an increase in rel.tive vel.city observed in ex.eriments. This impl.es that different dropl.t combustion model. shoul. be devel.ped in simu- l.ting spray combustion. The predicted l.cal.evaporation rate and fl.me radius by numerical.simul.tion are in agree- ment with the anal.tical.sol.tion in the range of azimuthal.angl.s 0° 〈 θ 〈 90°. The numerical.resul.s indicate that the drag force of an evaporating and combusting dropl.t is much smal.er than that of a col. sol.d particl., and thus the currentl. used drag model. shoul. be modified.
