Retouched notches at Combe Grenal (France) and the Reduction Hypothesis
, 2015 A detailed attribute analysis of notched flakes from upper layers of Combe Grenal, a key site in the debates about the nature of Middle Paleolithic assemblage variation in France, is used to evaluate the applicability to Combe Grenal of the reduction ...

Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Notches in animal teeth - artifical or natural/pathological?
, 1998 Animal teeth with notches at the root are sometimes found in archeological contexts. The notches are often considered to have been artificially engraved and the teeth regarded as artifacts of personal adornment.

Advanced Materials, EarlyView.Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

Use of J-integral to predict static failures in sharp V-notches and rounded U-notches
, 2008 In the present paper, the physical meaning of JV (namely, the classic J-integral applied to either sharp V-notch) is discussed. Consider a Cartesian reference frame having the x-axis parallel to the notch bisector, each mode of JV, for a given circular ...

Advanced Materials, EarlyView.Inspired by Acorus calamus leaves, a heterogeneous eutectic skin integrates an aligned fibrous network within a hydrophobic eutectogel matrix. This hierarchical architecture triggers strain‐induced crystallization to achieve exceptional mechanical toughness and durable wet adhesion.

Data‐Efficient Electromagnetic Surrogate Solver Through Dissipative Relaxation Transfer Learning
Advanced Optical Materials, EarlyView.Dissipative relaxation transfer learning (DIRTL) enables data‐efficient training of electromagnetic surrogate solvers by pretraining data generated with artificial material loss before fine‐tuning on target lossless data. The framework suppresses resonant outlier effects during early training, allowing effective adaptation to high‐amplitude resonances ...

Elastic stress distributions in finite size plates with edge notches
, 1998 In fatigue crack growth analysis it is essential to know the stress distributions in the neighbourhood of stress raisers. If such distributions ahead of the uncracked notch are known, stress intensity factors may be obtained via the weight function or ...
