A lightweight road-assistant detection algorithm， EBD-YOLO， based on YOLOv5s is proposed to address the problems of.high model complexity， computation cost， and dif.iculty in deployment on resource-limited embedded terminals in existing assisted driving detection algorithms. f.rst， lightweight Transf.rmer model Ef.icientViT was used as the backbone f.ature extraction network of.YOLOv5s model to reduce network parameters and calculation costs. Secondly， a f.cal-GIoU Loss f.nction is proposed f.r bounding box regression to accelerate model convergence and reduce loss. Thirdly， the f.ature pyramid structure is improved to a weighted bi-directional f.ature pyramid network (Bif.N) to enhance localization and semantic f.atures. Then， a dynamic head f.amework is added to unif. the attention mechanism with the object detection head to improve its perf.rmance. f.nally， a Sof.-CIoU＿NMS algorithm is proposed in the post-processing stage to enhance occluded targets' localization and detection ability and reduce the missed detection rate. We conducted experiments on the KITTI and BDD100K datasets f.r autonomous driving， and the results showed that the EBD-YOLO model reduced in size by 38.4% and 37.2%， respectively. In comparison， the computational cost was reduced by 48.1%. As measured by mAP@0.5， the detection accuracy improved by 0.5% and 5.8%， respectively， and mAP@0.5:0.95 improved by 2.8% and 7%， respectively. These improvements satisf.ed the requirements f.r deployment on embedded terminals in cars.

Laser shock f.rming （ISf. was a new technique realized by applying an impulsive pressure generated by laser-induced shock wave on the surf.ce of.metal sheet. LSf.of.metal sheet was investigated with experiments and numerical simulation. The basic theories were introduced; the surf.ce quality and def.rmation of.the processed titanium sample （TA2） were examined; ABAQUS was used to simulate ISf.and the central displacement of.the shocked region was measured and compared with the simulation. Overlapped ISf.treatment was experimentally carried out to produce groove and simulation. The results showed that the surf.ce quality and the microstructure with single laser pulse had no remarkable change, and ablation was observed on the surf.ce of.the sample with overlapped pulses. The def.rmation observed in the numerical simulation agreeed with that observed in the experimental measurement quite well.

While we may be comf.rtable with an allopathic approach to male inf.rtility, we are also responsible f.r knowledge about lif.style modif.cations and holistic, complementary, and alternative therapies that are used by many of.our patients. This paper provides an evidence-based review separating f.ct f.om f.ction f.r several of.these therapies. There is suf.icient literature to support weight reduction by diet and exercise, smoking cessation, and alcohol moderation. Supplements that have demonstrated positive ef.ects on male f.rtility on small randomized controlled trial （RCT） include aescin, coenzyme Qlo, glutathione, Korean red ginseng, L-carnitine, nigella sativa, omega-3, selenium, a combination of.zinc and f.late, and the Menevit antioxidant. There is no support f.r the use of.Vitamin C, Vitamin E, or saf.ron. The data f.r Chinese herbal medications, acupuncture, mind-body practice, scrotal cooling, and f.ith-based healing are sparse or inconclusive.

A metal-f.ee photocatalytic hydrogen evolution system was successf.lly f.bricated using heteroatom doped graphene materials as electron-transf.r co-catalysts and carbon nitride as a semiconductor. The catalytic role of.graphene is signif.cantly dependent on the heteroatom dopant of.the graphene, such as O, S, B, N doped/undoped graphene co-catalysts, and N-graphene shows the best catalytic hydrogen evolution rate.

The exchange of.energy and water between the lithosphere and atmosphere mainly takes place at the ground surf.ce. Theref.re, f.eeze/thaw condition at the ground surf.ce is an important f.ctor in ex- amining the interactions between the land surf.ce and atmosphere. Based on the observation data obtained by CEOP/CAMP-Tibet, the diurnal f.eeze/thaw cycles of.the ground surf.ce near Naqu, central Tibetan Plateau was preliminarily analyzed. The results show that the surf.ce layer was completely f.ozen f.r approximately one month. However, the time that the ground surf.ce experienced diurnal f.eeze/thaw cycles was about 6 months. The high f.equency of.f.eeze/thaw cycles at the ground surf.ce signif.cantly inf.uences water and energy exchanges between ground and atmosphere over half.a year. The interaction processes between the ground and atmosphere under dif.erent soil conditions (such as complete thaw, complete f.eeze and diurnal f.eeze/thaw cycles) are issues worthy of.f.rther examina- tion.

Three-point bending f.tigue experiments were conducted on a typical Zr-based bulk metallic glass(BMG)at ambient temperature to investigate the f.tigue behavior under cyclic loading *** show that the stress amplitude-cycles to f.ilure(S-N)curve of.the Zr-based BMG is determined,and the f.tigue endurance limit is 442 MPa(stress amplitude).To evaluate the probability-stress amplitude-cycles to f.ilure(P-S-N)curve,an estimation method based on maximum likelihood was proposed,which relies on statistical principles to estimate the f.tigue lif. of.the material and allows f.r a reduction in the number of.samples required,of.ering a cost-ef.ective and ef.icient alternative to traditional testing *** experimental results align with the American Society f.r Testing and Materials(ASTM)standard,indicating the reliability and accuracy of.this estimation method in evaluating the f.tigue behavior of.Zr-based BMG.
