The Impact of Hollow Wear on the Stability of High-Speed Railway Vehicles
Applied SciencesHollow wear on wheels is a common form of surface damage often observed in high-velocity vehicles. It is widely recognized that hollow wear of the wheel tread degrades the dynamic performance of rail vehicles, especially in the issue commonly referred to

Refinements on higher order Weil–Oesterlé bounds via a Serre type argument
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract Weil's theorem gives the most standard bound on the maximum number of points Nq(g)$N_q(g)$ of a curve of genus g$g$ over a finite field Fq$\mathbb {F}_q$. This bound was improved by Ihara and Oesterlé for larger genus. A recent point of view allows one to recover these bounds by solving a sequence of semi‐definite programs, and the first two ...

Piezo-Potential Generation in Capacitive Flexible Sensors Based on GaN Horizontal Wires
Nanomaterials, 2018 We report an example of the realization of a flexible capacitive piezoelectric sensor based on the assembly of horizontal c¯-polar long Gallium nitride (GaN) wires grown by metal organic vapour phase epitaxy (MOVPE) with the Boostream® technique

Pinwheels in symplectic rational and ruled surfaces and non‐squeezing of rational homology balls
Journal of Topology, Volume 19, Issue 3, September 2026.Abstract We use almost toric fibrations and the symplectic rational blow‐up to determine when certain Lagrangian pinwheels, which we call liminal, embed in symplectic rational and ruled surfaces. The case of L2,1$L_{2,1}$‐pinwheels, namely Lagrangian RP2s$\mathbb {R}P^2{\rm s}$, answers a question of Kronheimer in the negative, exhibiting a symplectic ...

Correlation of ultrasound measured testicular volume with waist circumference, hip circumference, waist-hip ratio and conicity index in Nigerian adults [PDF]
, 2018 Background: Accurate testicular volume measurement is one way to assess testicular function. Some obese males exhibit altered levels of circulating sex steroids; decreased levels of total testosterone (T) and sex hormone binding globulin (SHBG) and ...

Land Degradation &Development, Volume 37, Issue 14, Page 10387-10404, 30 August 2026.ABSTRACT The Yellow River Basin is a critical region for ecological conservation and sustainable development in China. It also serves as a core area for carbon emissions across various functional zones of construction land. Accurately understanding carbon emissions from various types of construction land in the Yellow River Basin is crucial for China ...

Wear of double crown systems: electroplated vs. casted female part
Journal of Applied Oral Science, 2012 OBJECTIVES: The wear of telescopic crowns is a common problem often reducing the patient's satisfaction with the denture and resulting in a renewal of the denture. The study aims to compare the wear behavior of conical crowns using electroplated copings (
