Hierarchically Rough rGO/HAp Nanocoatings on SLM Ti–6Al–4 V Implants for Enhanced Biointegration

open access: yesSmall, EarlyView.
This study investigates HAp/rGO bioactive coatings on Ti‐6Al‐4V fixation implants fabricated by selective laser melting with systematically varied volumetric energy density to tailor the as‐built surface state. Composite coatings were deposited by electrophoretic deposition and characterized using micro‐CT, profilometry, FESEM/EDS, and detailed XPS to ...

Using modular timber structure as a proposal to reduce the carbon footprint in civil engineering.

open access: yesDrewno
Construction is responsible for a significant impact on environmental pollution, depending on the source, it is about 40% of global carbon dioxide emissions (Global Alliance for Building and Construction; International Energy Agency 2019).

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

open access: yesStructural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Optimizing the embodied carbon of the product stage of reinforced concrete columns

open access: yesStructural Concrete, EarlyView.
Abstract The construction sector faces urgent sustainability challenges. This study quantifies the potential for reducing embodied carbon in reinforced concrete columns by optimizing concrete strength and reinforcement ratios. The interplay between concrete compressive strength (20–90 MPa), reinforcement percentages (0.2%–2.0%), and embodied carbon ...

Cerebral Protection During Transcatheter Aortic Valve Implantation: An Updated Systematic Review and Meta‐Analysis

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundThe use of embolic protection devices (EPD) may theoretically reduce the occurrence of cerebral embolic lesions during transcatheter aortic valve implantation. Available evidence from single studies is inconclusive.

Mitigating Financial Barriers to Trauma Care in Cameroon Through Locally Designed Quality Improvement

open access: yesWorld Journal of Surgery, EarlyView.
In low‐ and middle‐income countries, trauma patients frequently face delays and inequities in care due to out‐of‐pocket payment requirements for basic medical supplies. In Cameroon, such financial barriers may impede timely emergency treatment and worsen outcomes.

Using large language models to analyze political texts through natural language understanding

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Large language models (LLMs) offer scalable alternatives to human experts when analyzing political texts for meaning, using natural language understanding (NLU). Qualitative NLU methods relying on human experts are severely limited by cost and scalability.
