Flexible light-em.tting fibers and fabrics serve to bridge hum.n–m.chine interactions. The desire for practical applications and the com.ercialization of flexible light-em.tting fibers has accelerated structural progress and im.rovem.nts. This review focuses on the structural design of light-em.tting fibers and fabrics, starting with a sum.ary of design principles, em.ssion m.chanism., and structural evolution of coaxial structured light-em.tting fibers. Subsequently, we explore recent advances in the helical structure design strategies that boost the m.chanical sensitivity of light-em.tting fibers. Following that, we analyze continuous preparation processes and the developm.nt of large-area intelligent light-em.tting fabrics based on interwoven structures. Exam.les based on stiff and rigid inorganic-based lightem.tting diodes integrated into flexible system. are also presented. Finally, we discuss the current challenges and future opportunities for light-em.tting applications in the field of wearable and sm.rt devices.

Subalpine fir decline （SFD） has killed m.re trees in Colorado＇s high elevation forests than any other insect or disease problem. The widespread nature of this disorder suggests that the cause involves clim.tic factors. We exam.ned the influence of varying com.inations of average annual tem.erature and precipitation on the incidence and distribution of SFD. Clim.tic transition m.trices generated in this study indicate that m.st healthy trees are found in clim.tic zones with m.derate to low tem.eratures and high precipitation; whereas, SFD occurs m.stly in zones of m.derate tem.eratures and m.derate precipitation. The contrasting distributions define an environm.ntal m.sm.tch. Forests m.tched with favorable clim.tic conditions thrive; those that are m.sm.tched can becom. vulnerable to decline disease.

Sequencing revealed a novel pathogenic m.ssense variant(c.290A>G)in the cytosolic isoleucyl-tRNA synthetase gene,leading to an am.no acid substitution(***97Gly).Pathogenic variants in other genes associated with inflam.atory bowel disease(IBD)(ADAm.7,EGFR,FOXP3,IL10RA,IL10RB,IL21R,NCF4,STAT3)were *** assays dem.nstrated m.rkedly elevated IL-2,IL-5,IL-13,IL-9 and IL-10 by the patient’s CD4+T-cells,while IL-17A,IL-17F,IFNβwere lower,and TNFαnot significantly different when com.ared to healthy *** This case report provides evidence that recessive m.tations in cytosolic isoleucyltRNA synthetase are a novel m.nogenic cause of IBD,which should be considered,particularly in infants and children with a history of neonatal hepatitis and very early-onset IBD poorly responsive to treatm.nt.

The num.er of operational satellites and debris objects in the valuable geosynchronous ring has increased steadily over tim. such that active debris rem.val m.ssions are necessary to ensure long-term.stability. These objects are very large and tum.ling, m.king any m.ssion scenarios requiring physical contact very challenging. In the last 10 years, the concept of using an electrostatic tractor has been investigated extensively. With the electrostatic tractor concept, active charge em.ssion is em.loyed to sim.ltaneously charge the tug or services vehicle, while aim.ng the charge exhaust onto the passive space debris object to charge it as well. The resulting electrostatic force has been explored to actuate this debris object to a disposal orbit or to detum.le the object, all without physical contact. This paper provides a survey of the related research and reviews the charging concepts, the associated electrostatic force and torque m.deling, and the feedback control developm.nts, as well as the charge sensing research.
