Spacing-speed dependency on relative speeds to the adjacent lanes: a statistical test

, 2022
The spacing of a vehicle is the spatial separation between this vehicle and the vehicle ahead. It forms the basis of the fundamental diagram of traffic flow.

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Nacre‐inspired layered composite with excellent mechanical support and osteogenic potential for cervical interbody cage

BMEMat, EarlyView.
The cervical interbody cage needs to take both biomechanical and biological requirements into account. Here, a new‐style degradable, multicomponent, and bioinspired nacre‐like cervical interbody cage composite, which exhibits promising mechanical‐support‐related behavior and osteogenesis‐related potential, is designed and prepared.

Effect of microstructure on the cleavage fracture stress of high-speed railway wheel steel

工程科学学报, 2016
The microstructures with different grain sizes and pearlite interlamellar spacings of high-speed railway wheel steel with a carbon mass fraction of 0.54% were achieved by heat treatment at different austenitizing temperatures and cooling rates. Notched 3-

Unraveling Synergistic Regulation Mechanism in Nitrogen/Sulfur Co‐Doped Biomass‐Derived Hard Carbon Toward Durable Sodium‐Ion Battery Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nitrogen/sulfur co‐doping optimizes the electron and spatial structure of biomass‐derived hard carbon, and the anode demonstrates superior long‐term cycling stability over 2000 cycles, validating an improved “adsorption‐intercalation‐pore filling” mechanism.

Effect of the Interlamellar Spacing on Mechanical Properties of SWRS82B Wire Rod before and after Drawing

, 2010
The mechanical properties and microstructure of SWRS82B wire rods and drawn wire were studied. Wire rods were austenitized at 850°C~900°C and held at 500°C~600°C. The results show that the finer interlamellar spacing results in the higher yield strength,

Automatic measurement of pearlitic interlamellar spacing with computer image processing.

ISIJ International, 1990
For metallurgical studies or routine control of eutectoid steels, it is necessary to perform automatic measurement of pearlitic interlamellar spacing. Various methods, using a combined system of a scanning electron microscope (SEM) and an image analyzer (IA) have been compared and the optimum procedure has been studied.

Interplay Between Dispersion, Nucleation, and Crystallization in HDPE/Graphene Nanocomposites Processed Under Thermokinetic Conditions

Polymer Engineering &Science, EarlyView.
Thermokinetic processing controls graphene fragmentation and dispersion in HDPE, promoting heterogeneous nucleation and multistep crystallization. The balance between nucleation enhancement and chain mobility restriction governs the final crystalline structure and material performance.
