Grain boundary and texture evolution of TiB/Ti–2Al–6Sn titanium matrix composite under electroshocking treatment

This work used electroshocking treatment (EST) plus external loading to regulate the microstructure of titanium matrix composites (TMCs). The external loading was 0.3 MPa. After EST plus external loading with 0.3 MPa, the α was reduced to 2...

The Biomechanical Characteristics of Swallowing in Tracheostomized Patients with Aspiration following Acquired Brain Injury: A Cross-Sectional Study

Objectives: Investigate the biomechanical characteristics in tracheostomized patients with aspiration following acquired brain injury (ABI) and further explore the relationship between the biomechanical characteristics and aspiration. Metho...

Effect of Tunnel Ventilation on Hydrogen Dispersion From Leaks in Hydrogen Fuel Cell Trucks

ABSTRACT The widespread adoption of hydrogen fuel cell trucks (HFCTs) depends on addressing hydrogen safety concerns, particularly in confined spaces like tunnels, where effective ventilation is crucial to prevent accumulation during leaks....

Development of Representative Urban Driving Cycles for Congested Traffic Conditions in Guayaquil Using Real-Time OBD-II Data and Weighted Statistical Methods

Standardized driving cycles such as the FTP-75 fail to represent traffic conditions in cities like Guayaquil, where high congestion and varied driving behaviors are not captured by external models. This study aimed to develop representative...

Flexural Behaviour of Corroded RC Beams Strengthened with CFRCM: Refined Modelling, Parametric Analysis, and Design Assessment

Reinforced concrete (RC) beams strengthened with carbon-fabric-reinforced cementitious matrix (CFRCM) systems have shown potential for restoring flexural performance, yet their effectiveness under different corrosion levels remains insuffic...

Hybrid Dynamic Traffic Model for Freeway Flow Analysis Using a Switched Reduced-Order Unknown-Input State Observer

This paper introduces a new methodology for reconstructing vehicle densities of freeway segments by utilizing the limited data collected by traffic-counting sensors and developing a macroscopic traffic stream model formulated as a switched ...

TEMPERATURE OF SLIDING SURFACES OF INTERNAL COMBUSION ENGINES BY THE TEMPER COLORS OF WEAR PARTICLES

The present study examines the temper colors of the wear particles retained by the oil filter by optical microscope. The temperature of the sliding surfaces inside engines can be determined by the temper colors of the wear particles. Becaus...

Dependence of Freeze-Out Parameters on Collision Energies and Cross-Sections

We analyzed the transverse momentum spectra (pT) reported by the NA61/SHINE and NA49 experiments in inelastic proton–proton (pp) and central Lead–Lead (Pb−Pb), Argon–Scandium (Ar−Sc), and Beryllium–Beryllium (Be−Be) collisions with the Blas...

Influence of size effect on springback and thickness distribution of hydroformed ultra-thin metallic bellows

Ultra-thin metallic bellows are critical components in new energy vehicles and aerospace applications, yet their forming precision is significantly challenged by size effects when the wall thickness is reduced to the mesoscopic scale. This ...

Integrated-Hybrid Framework for Connected and Autonomous Vehicles Microscopic Traffic Flow Modelling

In this study, a novel traffic flow modeling framework is proposed considering the impact of driving system and vehicle mechanical behavior as two different units on the traffic flow. To precisely model the behavior of Connected and Autonom...

Semi-Resolved CFD-DEM Study on the Influence of ‘Surface Energy’ Factors on the Deposition of Lignin Particles in Ceramic Membrane Pores

This study adopted a semi‑analytical CFD‑DEM coupling method to simulate the movement and deposition of lignin particles in ceramic membrane pores, with the aim of elucidating the microscopic mechanisms of membrane fouling. The movement of ...

Investigation of the Friction Performance of G3000 (Variant), GG20, and GG15 (High Carbon) Cast Brake Discs Using the SAE J2522 Procedure

This study compares the friction performance of three commonly used cast brake disc materials in the automotive industry: the G3000 variant, GG20, and GG15 (high carbon content). Samples were tested on an inertia dynamometer following the S...

Additive roles of antiferromagnetically coupled elements in the magnetic proximity effect in the GdFeCo/Pt system

Abstract Interfacial magnetic interactions between different elements are the origin of various spin-transport phenomena in multi-elemental magnetic systems. We investigate the coupling between the magnetic moments of the rare-earth, transi...

To Be or Not to Be: Alicante-8, a Cluster or Not?

Recent surveys have uncovered new young massive clusters that host dozens of red supergiants (RSGs) near the inner Galaxy. However, many of them have still not been fully studied. Using Very Large Telescope/X-shooter near-infrared spectra, ...

Transient measurement of phononic states with covariance-based stochastic spectroscopy

Deuteron photodisintegration by polarized photons in the region of the d⁎(2380)

We report the first large-acceptance measurement of the beam–spin asymmetry for deuteron photodisintegration (γ→d→pn) in the photon energy range 420...

Pt and CoB trilayer Josephson $$\pi $$ π junctions with perpendicular magnetic anisotropy

Abstract We report on the electrical transport properties of Nb based Josephson junctions with Pt/Co $$_{68}$$ 68 B $$_{32}$$ 32 /Pt ferromagnetic barriers. The barriers exhibit perpendicular magnetic anisotropy, which has the main advantag...

Volcanic Pozzolan from the Phlegraean Fields in the Structural Mortars of the Roman Temple of Nora (Sardinia)

In this paper, we discuss the presence of volcanic pozzolans in the structural mortars of the Roman Temple of Nora in Sardinia (3rd c. AD), represented by pyroclastic rocks (pumices and tuffs) employed as coarse and fine aggregates. The pro...

Natural Earth Pigments as Geological Polymineral Systems: A Structured Approach to Provenance and Degradation Assessment in Heritage Science

Natural earth pigments are polymineral materials whose present composition may differ from the source because of selection, grinding, heating, mixing, binder incorporation, and later alteration. This study develops a structured method for s...
