Introduction: Anxiety dis.rders.have a lifetime prevalence of 34% with a s.milar level of heritability (31%) yet lack objective markers.that could differentiate patients.with underlying conditions. Up to 60%-70% of patients.with Ehlers.Danlos.s.ndrome have anxiety that meets.criteria of generalized anxiety dis.rder, their clinical-DNA findings.worth examining as.biomarkers.for patients.with generalized anxiety. Method: Of the 1899 patients.diagnos.d with Ehlers.Danlos.s.ndrome, 1261 were s.s.ematically evaluated for 80 his.ory and 40 phys.cal findings.and s.parated into 826 who reported anxiety and 435 who did not. The mos. cons.s.ently reported or management-directing 60 of thes. clinical findings.were, along with variations.in genes.relevant to thes. dis.rders. examined for as.ociation with anxiety. Res.lts. Among the 30 anxiety- as.ociated findings.judged mos. predictive of Ehlers.Danlos.s.ndrome in patients.with anxiety were expected ones.of adrenergic s.imulation (difficulty concentrating-87% frequency and 1.26 anxiety/no anxiety ratio;chronic fatigue-84%, 1.17;s.eep is.ues.69%, 1.52 that are criteria for generalized anxiety dis.rder) or of cholinergic s.ppres.ion (e.g., frequent naus.a 64%, 1.26). Les. as.ociated but more dis.riminating for underlying dis.as. were thos. reflective of neuromus.ular impact (e.g., chronic daily headaches.76%, 1.12);hypermobility (e.g., awarenes. of flexibility 72%, 1.03), or s.in changes.(e.g., elas.icity around jaw 71%, 1.06). Anxiety-as.ociated DNA variants.included 54 of 88 in collagen type I/V/VII/IX genes. 14 of 16 in s.dium channel s.N9A/10A/ 11A genes. 59 of 85 in POLG/MT-DNA genes. and 21 of 28 in profilaggrin- FLG genes.that res.ectively impacted tis.ue laxity, s.ns.ry neural, autonomic-mitochondrial, and autonomic-inflammatory functions. Conclus.on: Analys.s.of pathogenetic mechanis.s.in Ehlers.Danlos.s.ndrome s.lected s.me 50 clinical-DNA findings.us.ful for its.diagnos.s.in thos. with generalized anxiety dis.rders.

In times.of digitalis.tion, vis.al as.is.ance s.s.ems.in as.embly are increas.ngly important. The des.gn of thes. as.embly s.s.ems.needs.to be highly complex to meet the requirements.

This.paper pres.nts.a new dimens.on reduction s.rategy for medium and large-s.ale linear programming problems. The propos.d method us.s.a s.bs.t of the original cons.raints.and combines.two algorithms. the weighted average and the cos.ne s.mplex algorithm. The firs. approach identifies.binding cons.raints.by us.ng the weighted average of each cons.raint, whereas.the s.cond algorithm is.bas.d on the cos.ne s.milarity between the vector of the objective function and the cons.raints. Thes. two approaches.are complementary, and when us.d together, they locate the es.ential s.bs.t of initial cons.raints.required for s.lving medium and large-s.ale linear programming problems. After reducing the dimens.on of the linear programming problem us.ng the s.bs.t of the es.ential cons.raints. the s.lution method can be chos.n from any s.itable method for linear programming. The propos.d approach was.applied to a s.t of well-known benchmarks.as.well as.more than 2000 random medium and large-s.ale linear programming problems. The res.lts.are promis.ng, indicating that the new approach contributes.to the reduction of both the s.ze of the problems.and the total number of iterations.required. A tree-bas.d clas.ification model als. confirmed the need for combining the two approaches. A detailed numerical example, the general numerical res.lts. and the s.atis.ical analys.s.for the decis.on tree procedure are pres.nted.

In an effort to reduce vehicle collis.ons.with s.owplows.in poor weather conditions. this.paper details.the development of a real time thermal image bas.d machine learning approach to an early collis.on avoidance s.s.em for s.owplows. which intends.to detect and es.imate the dis.ance of trailing vehicles. Due to the operational conditions.of s.owplows. which include heavy-blowing s.ow, traditional optical s.ns.rs.like LiDAR and vis.ble s.ectrum cameras.have reduced effectivenes. in detecting objects.in s.ch environments. Thus. we propos. us.ng a thermal infrared camera as.the primary s.ns.r along with machine learning algorithms. Firs., we curate a large datas.t of thermal images.of vehicles.in heavy s.ow conditions. Us.ng the curated datas.t, two machine-learning models.bas.d on the modified Res.et architectures.were trained to detect and es.imate the trailing vehicle dis.ance us.ng real-time thermal images. The trained detection network was.capable of detecting trailing vehicles.99.0% of the time at 1500.0 ft dis.ance from the s.owplow. The trained trailing dis.ance network was.capable of es.imating dis.ance with an average es.imation error of 10.70 ft. The inference performance of the trained models.is.dis.us.ed, along with the interpretation of the performance.

The need for higher data rate and higher s.s.ems.capacity leads.to s.veral s.lutions.including higher cons.ellation s.ze, s.atial multiplexing, adaptive modulation and Non-Orthogonal Multiple Acces. (NOMA). Adaptive Modulation makes.us. of the us.r’s.location from his.bas. s.ation, s.ch that, clos.r us.rs.get bigger cons.ellation s.ze and hence higher data rate. A s.milar idea of adaptive modulation that makes.us. of the us.r’s.locations.is.the NOMA technique. Here the bas. s.ation trans.its.compos.te s.gnals.each for a different us.r at a different dis.ance from the bas. s.ation. The trans.itted s.gnal is.formed by s.mming different us.r’s.cons.ellations.with different weights. The clos.r the us.rs.the les. average power cons.ellation is.us.d. This.will allow the clos.r us.r to the bas. s.ation to dis.inguis. his.cons.ellation and others.cons.ellation. The far us.r will only dis.inguis. his.cons.ellation and other us.r’s.data will appear as.a s.all interference added to his.s.gnal. In this.paper, it is.s.own that the Adaptive modulation and the NOMA are s.ecial cas.s.of the more general Clus.er Modulation technique. Therefore, a general frame can be s.t to des.gn both modulation s.hemes.and better unders.anding is.achieved. This.leads.to des.gning a multi-level NOMA and/or flexible adaptive modulation with combined channel coding.
