Distinct distributions of myosin motor conformations during contraction of slow and fast skeletal muscle

The Journal of Physiology, EarlyView.
Abstract figure legend We recorded time‐resolved small‐angle X‐ray diffraction patterns from rat soleus muscles during fixed‐end twitch and tetanic contractions to investigate the structural basis of the lower fixed‐end force generated by these muscles compared with fast muscles, such as the mouse extensor digitorum longus (EDL).

Seismic Assessment Procedure for Exterior Reinforced Concrete Beam–Column Joints With Slab and Transverse Beams

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 8, Page 1655-1674, 10 July 2026.
ABSTRACT This article presents a capacity‐based assessment procedure for beam–column (b–c) joints of reinforced concrete frames with floor slabs and transverse beams. The procedure extends a previously proposed assessment methodology for determining the hierarchy of strengths and the sequence of events in symmetrically reinforced planar b–c joints.

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

Archaeometry, Volume 68, Issue 3, Page 298-310, June 2026.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Development of Initial Scantling Formulas for Submarine Deep Frames Based on Numerical Analysis

Journal of Marine Science and Engineering
Submarine structures are typically classified into pressure hulls and non-pressure hulls. The pressure hull is a critical component designed to withstand external pressure at operational depths while ensuring internal structural integrity.

Design, Fabrication and Test of Composite Curved Frames for Helicopter Fuselage Structure [PDF]

Aspects of curved beam effects and their importance in designing composite frame structures are discussed. The curved beam effect induces radial flange loadings which in turn causes flange curling.

Medium‐Cycle Fatigue Behavior of Three Metallic Materials and a Welded Steel Following Gaseous Hydrogen Soaking

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2395-2410, June 2026.
ABSTRACT This study investigates the impact of hydrogen soaking on the medium‐cycle fatigue behavior of various metallic materials commonly used in gas transmission pipelines. The tested materials include ex‐service gray cast iron, ex‐service X52 carbon steel, brass, and welded X52 carbon steel.

Issued as a Documentation Report on an Investigation of Field-Made Joints in Prestressed Reinforced Concrete Highway Girder Bridges, Project IHR-303, Phase 2 [PDF]

, 1977
A prototype bridge girder was designed, built, and tested. The 250 ft long two-span girder was made of 3 precast segments about 88, 74, and 88 ft in length. The segments were supported on 3 final and 2 temporary supports.

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

Journal of Anatomy, Volume 248, Issue 6, Page 1002-1025, June 2026.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...
