Arc plasma heat flow cutting, as a novel thermal cutting technology, shows excellent application prospects in the field of material processing. To achieve the control of heat and jet during the arc heat flow cutting proc...

Background: High tibial osteotomy (HTO) surgical accuracy may be improved by using CT-based pre-operative planning and patient-specific cutting guides (PSCGs). This randomized exploratory study aimed to assess the feasib...

ObjectiveCurrently, the insufficient full-element digitization and the prevalence of “data silos” in fully mechanized mining faces (FMMF) result in poor cutting precision and operational instability of shearers under...

Abstract Objective The relationship between muscle function recovery and biomechanical alterations after anterior cruciate ligament reconstruction (ACLR) during high-risk movements remains unclear. This study aimed to in...

This study proposes a deep-hole directional blasting technology based on polymer energy charge packages for roof cutting and pressure relief as a solution to difficult roadway support and poor stability of coal pillars d...

Electrochemical cutting with internal electrolyte jetting is a high-efficiency and high-precision machining technology suitable for cutting workpieces with a thickness exceeding 1 mm. In this process, a metal tube with...

Abstract The high-temperature rock drilling is a key process in the exploitation of the hot-dry-rock (HDR) geothermal energy. Understanding the abrasive characteristics of HDR is critical for drilling efficiency and cost...

Abstract This paper presents a four-wheel differential-drive (4WD) autonomous platform that consolidates grass cutting, collection, leaf crushing, and precision seeding through modular, quick-release toolheads. A vertica...

This study presents pioneering research addressing the challenge of surrounding rock control in gob-side entry retaining by roof cutting under the conditions of a gently inclined coal seam with an extra-thick main roof r...

Against the background of global climate change, increasingly severe drought stress exerts a significant impact on plant growth and yield. This study aimed to clarify the leaf anatomical structure, physiology and biochem...

In underground mining and tunneling projects, directional fracture-controlled blasting is critical for precise tunnel formation and reducing over- and under-excavation. However, the presence of well-developed joints in r...

ObjectiveTo improve the rock-breaking efficiency and durability of drill bits in the theoretical research on the optimal design of drill bits, the key is to systematically reveal both the rock-breaking mechanisms of poly...

ObjectiveLimestone water hazards in coal seam floors represent one of the two primary categories of mine water hazards in China. Limestone aquifers are generally characterized by abundant static water reserves and consid...

Abstract Accurate specimen preparation is essential for biomechanical push-out testing of bone–implant interfaces. A common source of error arises when implants such as pins or screws are not cut exactly perpendicular ...

Abstract Contrast enhancement technique is a prevalent problem in aiding interpretation of Magnetic Resonance Imaging (MRI) images. A low contrast MRI image may prove to be problematic in identifying medical problems suc...

Abstract The increasing availability of positional data in invasion sports like football drives the development of advanced performance metrics. Two widely adopted examples are space control, which quantifies spatial inf...

This study aims to analyze and understand the integration of digital competences into official curricula in Europe during the early years of basic education. The research utilized document analysis, systematically and ca...

Ultimate Frisbee, a high intensity noncontact sport, poses significant injury risks due to the dynamic demands of sprinting, cutting, and jump landings. These injuries negatively impact athletic performance and carry pot...

Abstract Abdominal aortic aneurysm (AAA) is a common cardiovascular disease resulting in high mortality rate due to rupture. Intraluminal thrombus (ILT) is involved in AAA progression via both biomechanically protective ...

Abstract In this study, aluminium (Al) matrix composites reinforced with 0, 5, and 10 vol% silicon carbide (SiC) particles were fabricated by direct hot-pressing under 35 MPa pressure at 600 °C for a holding time of 5...

Nearly Zero Energy Buildings (NZEBs) are pivotal in addressing the escalating energy and environmental challenges of hot climates, where extreme cooling demands and reliance on fossil fuels intensify carbon footprints. T...

Abstract Superalloy is the only utilizable material for underground coal gasification channel joint. In this research, the high temperature gas flow erosion wear behavior of superalloy with strengthened layer by boronizi...

Abstract Congestion pricing effectively manages road travel demand but raises affordability concerns for lower-income groups. This study evaluates potential implementations of cordon pricing in downtown San Francisco and...
