Hereditary Optic Neuropathy (Leber\u27s Hereditary Optic Neuropathy)

open access: yes, 2022
Hereditary Optic Neuropathy - A hereditary optic neuropathy is caused by a genetic variant (or mutation) that causes dysfunction of the neurons (nerve cells) which form the optic nerve.

Past, present and future of local crop evolution

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Shear behaviour and theoretical model of large shear key dry joints in precast concrete segmental bridges using advanced monitoring

open access: yesStructure and Infrastructure Engineering
Keyed dry joints are commonly utilised in segmental bridges for shear stress transmission. The aim of this study is to explore the shear behaviour and capacity of large shear key dry joints.

Performance-based optimization for strut-tie modeling of structural concrete

open access: yes, 2002
Conventional trial-and-error methods are not efficient in developing appropriate strut-and-tie models in complex structural concrete members. This paper describes a performance-based optimization (PBO) technique for automatically producing optimal strut ...

Chemical diversity and phylogenetic insights into Hawaiian ʻākia (Wikstroemia) species used in traditional fishing practices

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...

PDA‐Engineered 3D‐Printed Polymer–ZrO2 Hybrid Scaffolds Enabling Enhanced Radiopacity, Photothermal Therapy, and Cell Migration Modulation

open access: yesSmall, EarlyView.
A multifunctional 3D‐printed polymer–ZrO2 scaffold is developed to provide intrinsic radiopacity, photothermal responsiveness, and surface bioactivity. Reinforcement with ZrO2 enables real‐time x‐ray visibility and mechanical robustness, while a polydopamine coating facilitates near‐infrared‐triggered drug release and modulates cell migration, thereby ...

Hierarchically Engineered Nanocellulose‐Halloysite Composite Foams for Integrated Thermal Insulation and Intrinsic Fire Resistance

open access: yesSmall, EarlyView.
Hierarchically engineered cellulose‐based nanocomposite foams integrate thermal insulation, mechanical robustness, hydrophobicity, and intrinsic flame retardancy. A multiscale hybrid network enables efficient heat and mass transport suppression, promoting char formation and self‐extinguishing behavior without toxic additives.

Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

open access: yesSmall Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures

open access: yesStructural Concrete, EarlyView.
Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐
