Collateralization of the Body in the Central Sahara: On Forms and Effects

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT This article tracks a transporter along the route linking Tripoli to the Saharan town of Ghadames in post‐2011 Libya, asking what secures an obligation when the institutions that normally underwrite it (offices, courts, recognized names) have receded. I distinguish the debt, the sum owed, from the security pledged to answer for it: what may be

Ultra‐Tough Hybrid Supramolecular Gelatin Hydrogels

open access: yesSmall, EarlyView.
Tannic acid‐mediated coacervation compacts gelatin into a dense supramolecular network while generating an acidic microenvironment that activates pre‐embedded bis‐oxazoline crosslinkers. The resulting hybrid hydrogel combines covalent stabilization with reversible energy dissipation, producing high strength, extreme extensibility, substantial toughness,

Engineering Flexible Nanofibrous Hydroxyapatite Scaffolds With Tunable Degradation and Mechanical Properties for Bone Regeneration

open access: yesSmall, EarlyView.
Conventional hydroxyapatite ceramics are brittle and poorly resorbable, limiting their use in bone repair. To overcome these limitations, flexible scaffolds are fabricated using ceramic nanofibers as structural building blocks. Adjusting nanofiber characteristics allows modulating the mechanical properties and degradation, providing a versatile ...

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

open access: yesSmall, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

From section to structure: Assessing the impact of localized corrosion on reinforced concrete beams

open access: yesStructural Concrete, EarlyView.
Abstract The structural behavior of reinforced concrete (RC) elements affected by localized corrosion represents a major challenge for ensuring structural safety and for the proper design of strengthening interventions. The effects of localized corrosion on the flexural behavior of RC beams remain a topic of debate within the scientific community.

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

open access: yesStructural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

Testing and modeling reinforced 3D concrete printing

open access: yesStructural Concrete, EarlyView.
Abstract 3D Concrete Printing (3DCP) provides several advantages, including construction productivity and sustainability, although the presence of cold joints reduces structural performance, particularly in zones subjected to tensile stresses. In addition, it is difficult to reinforce 3DCP structures with conventional steel rebars, generally used to ...

Contribution of dowel action to interfacial shear transfer in flat joints with unbonded posttensioned bars for precast segmental bridges

open access: yesStructural Concrete, EarlyView.
Abstract Dry joints are widely used in precast segmental bridge construction because they simplify assembly and accelerate erection. Incorporating fasteners crossing flat dry joints represents an innovative configuration for this type of connection.

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges

open access: yesBritish Journal of Pharmacology, EarlyView.
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...
