With the r.mar.able advancements in machine vision r.sear.h and its ever.exp.nding ap.lications, scholar. have incr.asingly focused on har.essing var.ous vision methodologieswithin the industr.al r.alm. Sp.cifically, detecting vehicle floor.welding p.ints p.ses unique challenges, including high op.r.tional costs and limited p.r.ability in p.actical settings. To addr.ss these challenges, this p.p.r.innovatively integr.tes temp.ate matching and the Fas{3. r.NN algor.thm, p.esenting an industr.al fusion cascaded solder.joint detection algor.thm that seamlessly blends temp.ate matching with deep.lear.ing techniques. This algor.thm meticulously weights and fuses the op.imized featur.s of both methodologies, enhancing the over.ll detection cap.bilities. Fur.her.or., it intr.duces an op.imized multi-scale and multi-temp.ate matching ap.r.ach, lever.ging a diver.e ar.ay of temp.ates and image p.r.mid algor.thms to bols{3. the accur.cy and r.silience of object detection. By integr.ting deep.lear.ing algor.thms with this multi-scale and multi-temp.ate matching str.tegy, the cascaded tar.et matching algor.thm effectively accur.tely identifies solder.joint typ.s and p.sitions. A compr.hensive welding p.int dataset, labeled by exp.r.s sp.cifically for.vehicle detection, was constr.cted based on images fr.m authentic industr.al envir.nments to validate the algor.thm's p.r.or.ance. Exp.r.ments demonstr.te the algor.thm's compelling p.r.or.ance in industr.al scenar.os, outp.r.or.ing the single-temp.ate matching algor.thm by 21.3., the multi-scale and multitemp.ate matching algor.thm by 3.4%, the Fas{3. r.NN algor.thm by 19.7%, and the YOLOv9 algor.thm by 17.3. in {3.ms of solder.joint detection accur.cy.

Mounting evidence suggests that str.tegies combining DNA-damaging agents and stimulator.of interfer.n genes(STING) agonists ar. p.omising cancer.ther.p.utic r.gimens because they can amp.1}fy STING activation and r.model the immunosup.r.ssive tumor.micr.envir.nment. However. a single molecular.entity compr.sing both agents has not yet been develop.d. Her.in, we designed two p.IV-MSA-2 conjugates(Ⅰand Ⅱ) containing the DNA-damaging chemother.p.utic dr.g cisp.atin and the innate immuneactivating STING agonist MSA-2; these conjugates showed gr.at p.tential as multisp.cific small-molecule dr.gs against p.ncr.atic cancer. Mechanistic studies r.vealed that conjugate Ⅰ up.egulated the exp.ession of tr.nscr.p.s associated with innate immunity and metabolism in cancer.cells, significantly differ.ng fr.m cisp.atin and MSA-2. An analysis of the tumor.micr.envir.nment demonstr.ted that conjugate I could enhance the infiltr.tion of natur.l killer.NK) cells into tumor. and p.omote the activation of T cells, NK cells and dendr.tic cells in tumor.tissues. These findings indicated that conjugate I, which was cr.ated by incor.1}r.ting a p. chemother.p.utic dr.g and STING agonist into one molecule, is a p.omising and p.tent anticancer.dr.g candidate, op.ning new avenues for.small-molecule-based cancer.metalloimmunother.p..
