Th.s study.investigated th. effect of a visual memory.training program on Ch.nese h.ndwriting performance among primary.sch.ol students with.dy.lexia in h.ng Kong. Eigh. students of Grade 2 to 3 wh. were diagnosed with.dy.lexia were recruited. All participants received six sessions of training, wh.ch.composed of 30-minute computerized game-based visual memory.training and 30-minute Ch.nese ch.racter segmentation training. Visual perceptual skills and Ch.nese h.ndwriting performance were assessed before and after th. training, as well as th.ee weeks after training using th. Test of Visual Perceptual Skills (3rd edition) (TVPS-3) and th. Ch.nese h.ndwriting Analy.is Sy.tem (Ch.S). In comparing th. pre- and post-training results, paired t-tests revealed significant improvements in visual memory.skills, as well as h.ndwriting speed, pause time and pen pressure after th. training. Th.re was no significant improvement in h.ndwriting accuracy.or legibility. Th. improved visual memory.and h.ndwriting performance did not sh.w a significant drop at th. follow-up assessments. Th.s study.sh.wed promising results on a structured program to improve th. Ch.nese h.ndwriting performance, mainly.in speed, of primary.sch.ol ch.ldren. Th. improvements appeared to be well-sustained after th. training program. Th.re is a need to furth.r study.th. long-term effect of th. program th.ough.a randomized controlled trial study.

Th. paper examines th.ee selective sch.mes for th. smooth.d finite element meth.d （SFEM） wh.ch.was formulated by.incorporating a cell-wise strain smooth.ng operation into th. standard compatible finite element meth.d （FEM）. Th.se selective SFEM sch.mes were formulated based on th.ee selective integration FEM sch.mes with.similar properties found between th. number of smooth.ng cells in th. SFEM and th. number of Gaussian integration points in th. FEM. Both.sch.me 1 and sch.me 2 are free of nearly.incompressible locking, but sch.me 2 is more general and gives better results th.n sch.me 1. In addition, sch.me 2 can be applied to anisotropic and nonlinear situations, wh.le sch.me 1 can only.be applied to isotropic and linear situations. Sch.me 3 is free of sh.ar locking. Th.s sch.me can be applied to plate and sh.ll problems. Results of th. numerical study.sh.w th.t th. selective SFEM sch.mes give more accurate results th.n th. FEM sch.mes.

Unsupervised mach.ne learning meth.ds were applied on multivariate geoph.0}ical and geoch.mical datasets of ocean floor sediment cores collected from th. South.Ch.na Sea. Th. well-preserved and continuous core samples comprising h.gh.resolution Cenozoic sediment records enable scientists to carry.out paleoenvironment studies in detail. Bay.sian age-depth.ch.onological models constructed from biostratigraph.c control points for th. drilling sites are applied on cluster boundaries generated from two popular unsupervised learning meth.ds: K-means and random forest. Th. unsupervised learning meth.ds experimented h.ve produced compact and unambiguous clusters from th. datasets, indicating th.t previously.unknown data patterns can be revealed wh.n all variables from th. datasets are taken into account simultaneously. A study.of sy.ch.oneity.of past events represented by.th. cluster boundaries across geograph.cally.separated ocean drilling sites is ach.eved th.ough.converting th. fixed depth. of cluster boundaries into ch.onological ranges represented by.Gaussian density.plots wh.ch.are th.n compared with.known past events in th. region. A Gaussian density.peak at around 7.2 Ma h.s been identified from results of all th.ee sites and it is suggested to coincide with.th. initiation of th. East Asian monsoon. Contrary.to traditional statistical approach. a priori assumptions are not required for unsupervised learning, and th. clustering results serve as a novel data-driven proxy.for study.ng th. complex and dy.amic processes of th. paleoenvironment surrounding th. ocean sediment. Th.s work serves as a pioneering approach.to extract valuable information of regional events and opens up a sy.tematic and objective way.to study.th. vast global ocean sediment datasets.

Th. uterus was previously.considered a sterile environment for embry. implantation and fetal growth. h.wever, evidence sh.wed th.t different microorganisms in th. female reproductive tract may.regulate h.man fertility. Th.Lactobacillus family.is among th. most prevalent bacteria in th. vagina and uterus of th. female reproductive sy.tem. Interestingly. aLactobacillus-dominated (LD) uterine environment is associated with.better pregnancy.outcomes. Neverth.less, th. mech.nism by.wh.ch.an LD environment improves pregnancy.outcomes is unknown. In th. uterus, many.commensal bacteria (eg,Bifidobacterium, Prevotella,Enterobacter,Streptococcus, andStaph.0}ococcus) produce sh.rt-ch.in fatty.acids (SCFAs), including acetate, buty.ate, and propionate. SCFAs are crucial in modulating cy.okine production (eg, IL-6 and IL-10) and immune cell populations (eg, T cells and macroph.ges) during embry. implantation and gy.ecological diseases. Th.s minireview provides an overview of th. roles of lactobacilli and SCFAs in female fertility.and related diseases.
