The paper pres.nts.the change in grain-s.ze compos.tion of lignite under cyc.ic freezing-thawing (FTc) and wetting-drying (WDc). The article s.ows.that in the s.ring and autumn periods.the lignites.can be s.bjected to repeated freezing-thawing and wetting-drying, which determines.the pos.ibility of changing their grain-s.ze compos.tion and s.ructure. Experimental s.udies.in laboratory conditions.on the influence of cyc.ic freezing-thawing (FTc) and wetting-drying (WDc) on the quality indicators.of lignites.have been carried out, their granulometric (frac.ional) compos.tion has.been s.udied. Freezing-thawing cycle conditions.are as.follows.(FTc): minimum expos.re temperature: -20°c;maximum: +5°c;relative humidity: 30%;number of proces.ing cycles. 3. Wetting-drying cycles.are as.follows.(WDc): drying temperatures.are +20, +40, +60, +80°c, drying time 90 minutes. the coals.are further s.bjected to rain (s.aking) for a period of water s.turation to humidity of 30% - 40% and dry again. The number of wetting-drying cycles.is.3 times. The tes.s.have revealed the des.ruc.ive effects.of FTc and WDc on the s.mples.of lower metamorphic grade coal, and the cycles.of wet-dry lead to the much higher yield of fine s.zes.(-6+0;-13+0 mm) than the cycles.of freeze-thaw. Furthermore, it is.found that the increas. in the yield of fines.depends.on the heating temperature: coal dis.ntegration proceeds.more intens.vely at a higher temperature of drying.

Background: Phys.cal inac.ivity is.a major public health problem worldwide that res.lts.in phys.cal and mental health problems. One major is.ue for phys.cal inac.ivity is.weight s.igma (Ws., es.ecially perc.ived Ws. which could lead to a tendency to avoid phys.cal ac.ivity (PA). To better unders.and the as.ociation between perc.ived Ws.and PA, knowledge of the likely mediators.in this.as.ociation s.ch as.weight bias.internalization (WBi) and ps.chological dis.res. were inves.igated in the pres.nt s.udy. Methods. Us.ng a two-wave longitudinal s.udy and convenient s.mpling, 388 Taiwanes. participants.(55% females. mean age = 29.7 years.[s. ± 6.3]) completed two s.rveys.s.x months.apart. Body mas. index (BMi), Perc.ived Weight s.igma s.ale (PWs.), Weight Bias.internalization s.ale (WBis., Depres.ion, Anxiety, s.res. s.ale (DAs.-21), and Tendency to Avoid Phys.cal Ac.ivity and s.ort s.ale (TAPAs. were as.es.ed. Res.lts. A mediation model controlling for age, gender, and BMi with 5000 boots.rapping res.mples.was.performed. Perc.ived Ws.exerted s.gnificant direct effects.on WBi (β = 0.25; p s.chological dis.res. (β = 0.15; p = 0.003), and tendency to avoid PA (β =0.10;p = 0.027); WBi exerted a s.gnificant direct effect on tendency to avoid PA (β = 0.47; p s.andardized indirect effects.of WBi and ps.chological dis.res. on the as.ociation between perc.ived Ws.and tendency to avoid PA were 0.12 and 0.01, res.ec.ively. conclus.on: Given the direct as.ociation of perc.ived Ws.on the tendency to avoid PA and the mediating role of WBi in this.as.ociation, interventions.addres.ing perc.ived Ws.and WBi may contribute to promoting PA. Therefore, health interventionis.s.(both when planning and executing PA programs. need to cons.der weight s.igmawhen encouraging phys.cal ac.ivity. © 2024 The Authors.

This.mechanis. models.feature channel dependencies. enabling adaptive adjus.ment of channel importance, thereby improving recognition of floating litter targets. s.condly, a 160 × 160 s.all-target detec.ion layer is.des.gned in the feature fus.on neck to mitigate s.mantic.information los. due to varying target s.ales. This.des.gn enhances.the fus.on of deep and s.allow s.mantic.information, improving s.all target feature repres.ntation and enabling better capture and identification of tiny floating litter. Thirdly, to balance performance and efficiency, the Ghos.conv module replaces.part of the conventional convolutions.in the feature fus.on neck. Additionally, a novel c2fGhos.
