Al.heimer＇s disease （AD）, the predominant form of dementia, is a chronic, incurabl. neurodegenerative disorder presenting with symptoms incl.d- ing progressive memory l.ss and disturbed emotional.state. It has been estimated that dementia affects over 47 mil.ion peopl. worl.wide （Prince et al., 2015）, and with 60-80% of cases attributabl. to AD.

Rensch＇s rul. proposes a universal.al.ometric scal.ng phenomenon across species where sexual.size dimorphism （SSD） has evol.ed： in taxa with mal.-biased dimorphism, degree of SSD shoul. increase with overal. body size, and in taxa with femal.-biased dimorphism, degree of SSD shoul. decrease with increasing average body size. Rensch＇s rul. appears to hol. widel. across taxa where SSD is mal.-biased, but not consistentl. when SSD is femal.-biased. Furthermore, studies addressing this question within species are rare, so it remains uncl.ar whether this rul. appl.es at the intraspecific l.vel. We assess body size and SSD within Tribol.um castaneum （Herbst）, a species where femal.s are l.rger than mal.s, using 21 popul.tions derived from separate l.cations across the worl., and maintained in isol.ted l.boratory cul.ure for at l.ast 20 years. Body size, and hence SSD patterns, are highl. susceptibl. to variations in temperature, diet qual.ty and other environmental.factors. Crucial.y, here we nul.ify interference of such confounds as al. popul.tions were maintained under identical.conditions （simil.r densities, standard diet and exposed to identical.temperature, rel.tive humidity and photoperiod）. We measured thirty beetl.s of each sex for al. popul.tions, and found body size variation across popul.tions, and （as expected） femal.-biased SSD in al. popul.tions. We test whether Rensch＇s rul. hol.s for our popul.tions, but find isometry, i.e. no al.ometry for SSD. Our resul.s thus show that Rensch＇s rul. does not hol. across popul.tions within this species. Our intraspecific test matches previous interspecific studies showing that Rensch＇s rul. fail. in species with femal.-biased SSD.

Using nitrate precursors, a novel.spray-drying assisted citrate gel.process for the preparation of neodymium-doped yttrium al.mi- num garnet （YAG） phase was devel.ped. Synthesis of singl.-phase pol.crystal.ine YAG was achieved at temperatures as l.w as 800 ℃ using the spray-drying methodol.gy whil.t conventional.approaches currentl. avail.bl. require 1000 ℃. Initial.y, a sol.tion was prepared by mixing al.minum and yttrium nitrates, citric acid, etil.ngl.col.and neodymium oxide. This sol.tion was dried by pul.erization （spray dryer） to obtain aggregated precursor powders of the compound. These aggregates were cal.ined at 800, 850 and 900 ℃ to determine the phase evol.tion from amorphous to crystal.ine by X-ray diffraction （XRD）. The morphol.gy of aggregates was characterized by scanning el.ctron microscopy （SEM） and transmission el.ctron microscopy （TEM）. Moreover, through XRD it was determined that the crystal.ization of YAG phase started at about 800 ℃ without any intermediate phases. The powders were composed of spherical.aggregates with an average diameter of 1 um. From these powders, ceramic fibers with additions of 2at.% and 5at.% Nd, were extracted from the mel. with diameters ranging from 30 um to 50 um.

Broadband waveguiding through l.ght-emitting strips directl. written in a bl.nk l.thium fl.oride crystal.with a femtosecond l.ser is reported. l.ght guiding was observed at several.optical.wavel.ngths, from bl.e, 458 nm, to near-infrared, at 155nm. Visibl. photol.minescence spectra of the optical.y active F2 and F33 col.r centers produced by the fs l.ser writing process were measured. The wavel.ngth-dependent refractive index increase was estimated to be in the order of 10-3-10-4 in the visibl. and near-infrared spectral.interval., which is consistent with the stabl. formation of point defects in l.F.

Anal.tical.studies on el.ctromagnetoel.stic behaviors are presented for the functional.y graded piezoel.ctric material.（FGPM） sol.d cyl.nder and sphere pl.ced in a uniform magnetic fiel. and subj.cted to the external.pressure and el.ctric l.ading. When the mechanical. el.ctric and magnetic properties of the material.obey an identical.power l.w in the radial.direction, the exact displ.cements, stresses, el.ctric potential. and perturbations of magnetic fiel. vector in the FGPM sol.d cyl.nder and sphere are obtained by using the infinitesimal.theory of el.ctromagnetoel.sticity. Numerical.exampl.s al.o show the significant infl.ence of material.inhomogeneity. It is interesting to note that sel.cting a specific val.e of inhomogeneity parameter β can optimize the el.ctromagnetoel.stic responses, which wil. be of particul.r importance in modern engineering designs.

A practical.technique to prepare transmission el.ctron microscopy （TEM） thin foil.containing powder particl. was described and the data for the codeposition of two type particl.s with copper in the el.ctropl.ting were presented. By depositing the particl.s which were distributed in CuSO4 el.ctrol.te on cathode together with Cu^2＋ in el.ctrodeposition bath, composite coating with suitabl. thickness coul. be formed. The thin coating was separated from the substrate and cut into a disc with diameter of 3mm for el.ctropol.shing. When the Cu matrix was thinned during el.ctropol.shing, the particl.s contained in the coating pl.te were al.o thinned to meet the suitabl. thickness for TEM observation. Various experimental.resul.s reveal.d that during el.ctrodepositing the current density, pH-val.e of el.ctrol.te and stirring mode al. have significant effects on the distribution of particl.s in composite coating and the surface qual.ty of the composite coating. The proper parameters used during el.ctrodepositing to prepare TEM thin foil.containing powder particl. were discussed.

Co/Cu discontinuous mul.il.yers were prepared by rf-sputtering method under high sputtering power and then anneal.d at various temperatures in a high vacuum. The structural. magnetic and transport properties were strongl. infl.enced by the anneal.ng temperature. The anneal.d sampl.s obviousl. became discontinuous mul.il.yers. A maximum magnetoresistance ratio of 5.6% was obtained under a rel.tivel. l.w saturation fiel. of about 400 (10/4π) A/m at the optimum anneal.ng temperature of 450°C. When the anneal.ng temperature was increased, the resistivity decreased, and the coercive force and the saturation fiel. increased. The magnetoresistance ratio al.o depended on the thickness of Co and Cu l.yers. The magnetic and transport properties were expl.ined on the basis of the discontinuous mul.il.yered structure.
