Piese de metal, os, sticlă şi piatră descoperite în cetatea de la Caraşova-Grad (com. Caraşova, jud. Caraş-Severin)

open access: yesMateriale și Cercetări Arheologice, 2011
During the archaeological excavations made in Caraşova-Grad fortress (comm. Caraşova, Caraş-Severin County) in 1998, 2000 and 2001, a relatively great number of metal, glass, bone and stone items was discovered. The majority of these items were not found

Activation of NF‐κB Signaling by Optogenetic Clustering of IKKα and β

open access: yesAdvanced Biology, EarlyView.
This study presents an optogenetic approach for graded clustering of eGFP‐fused proteins using an eGFP‐specific nanobody and engineered Cryptochrome 2 variants. The method enables potent, reversible activation of NF‐κB signaling via endogenous pathways, as confirmed by RNA sequencing. This versatile system provides a spatially and temporally controlled

The Effect of Elastic–Plastic Mismatch and Interface Proximity on the Fracture Toughness of Ti‐TiN Thin Films

open access: yesAdvanced Engineering Materials, EarlyView.
Multilayering of TiN film with metallic Ti film is adopted to enhance the fracture resistance of TiN thin films. Plastic dissipation within Ti with process zone size of ≈250 nm, along with elastic–plastic mismatch driven changes to crack driving force enhances the crack growth resistance by ten times, enabling physics informed design of optimized ...

Lower Bounds for the Complexity of Monadic Second-Order Logic

open access: yes, 2010
Courcelle's famous theorem from 1990 states that any property of graphs definable in monadic second-order logic (MSO) can be decided in linear time on any class of graphs of bounded treewidth, or in other words, MSO is fixed-parameter tractable in linear

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

La couverture des toits des châteaux savoyards aux xiiie et xive siècles : un patchwork de matériaux

open access: yesArchéologie Médiévale
The accounts of castellenies and tolls of the county of Savoy and to a lesser extent those of the Dauphiné abound, for the 13th and 14th centuries, with a wealth of information relating to the repairs and renewal of the roofs of the castral buildings ...
