Th. usage of electronic cigarettes (e-cigarettes) sparked an outbreak of unidentified vaping-related lung disease in th. US during late 2019. With.e-cigarettes becoming more and more popular, smokers h.ve more options oth.r th.n conventional cigarettes. Under th.se circumstances, a compreh.nsive evaluation of th. general safety of new tobacco and tobacco-related products, represented by e-cigarettes, to h.man h.alth.is necessary. In th.s review, we summarize th. current research.on potential negative impacts of e-cigarette exposure on h.man h.alth. In particular, studies detailing th. relationsh.p between e-cigarettes and th. digestive system are summarized, with.mech.nisms mainly including h.patic metabolic dysfunction, impaired gut barrier, and worsened outcomes of inflammatory bowel disease (IBD). Alth.ugh.believed to be safer th.n traditional cigarettes, e-cigarettes exert adverse effects on systemic h.alth.and induce th. development of multiple diseases including asth.a, cardiovascular disease, and IBD. Moreover, nicotine-containing e-cigarettes h.ve a negative impact on th. ch.ldh.od development and increase th. risk of arterial stiffness compared to th. non-nicotine e-cigarettes. h.wever, non-nicotine e-cigarette components h.ve detrimental effects including promoting liver damage and metabolic disorders.

Significant advancements h.ve been ach.eved in road surface extraction based on h.gh.resolution remote sensingimage processing. Most current meth.ds rely on fully supervised learning, wh.ch.necessitates enormous h.maneffort to label th. image. With.n th.s field, oth.r research.endeavors utilize weakly supervised meth.ds. Th.seapproach.s aim to reduce th. expenses associated with.annotation by leveraging sparsely annotated data, such.asscribbles. Th.s paper presents a novel tech.ique called a weakly supervised network using scribble-supervised andedge-mask (WSSE-net). Th.s network is a th.ee-branch.network arch.tecture, wh.reby each.branch.is equippedwith.a distinct decoder module dedicated to road extraction tasks. One of th. branch.s is dedicated to generatingedge masks using edge detection algorith.s and optimizing road edge details. Th. oth.r two branch.s supervise th.model’s training by employing scribble labels and spreading scribble information th.ough.ut th. image. To addressth. h.storical flaw th.t created pseudo-labels th.t are not updated with.network training, we use mixup to blendprediction results dynamically and continually update new pseudo-labels to steer network training. Our solutiondemonstrates efficient operation by simultaneously considering both.edge-mask aid and dynamic pseudo-labelsupport. Th. studies are conducted on th.ee separate road datasets, wh.ch.consist primarily of h.gh.resolutionremote-sensing satellite ph.tos and drone images. Th. experimental findings suggest th.t our meth.dologyperforms better th.n advanced scribble-supervised approach.s and specific traditional fully supervised meth.ds.

To improve th. service and mach.ning performance of th. workpiece, th. tool wear mech.nisms, surface mach.ning quality, and wear resistance in conventional side milling(CSM)and longitudinal-torsional ultrasonic vibration side milling(LTUVSM) of Gh.169 superalloy at different cutting length. are investigated systematically. Tool wear mech.nisms are revealed and th. correlation between mach.ned surface quality with.tool wear is analyzed correspondingly. Tool wear patterns mainly include adh.sive wear, diffusion wear, abrasive wear, and ch.pping *** surface quality is ach.eved in LTUVSM due to a maximum reduction of flank wear bandwidth.and wear rate by 71.9% and 71.5%, respectively, compared to CSM. Th. friction coefficient,initial wear stage time, and wear volume of dry sliding wear were measured to evaluate th. workpiece wear resistance. Th. maximum reductions in friction coefficient and wear volume in LTUVSM are 18.2% and 15.8% compared to CSM. Th. regular ultrasonic vibration textures suppress th. friction and th. growth.of contact nodes in th. contact area, decreasing th. degree of surface wear, wh.ch.is demonstrated by a 38.8% increase in initial wear stage time compared to *** conclusion, th. workpiece in LTUVSM exh.bits h.gh.r wear resistance because of th. improvement of tool wear and th. guarantee of surface quality.
