‘The uses of ethnography in the science of cultural evolution’. Commentary on Mesoudi, A., Whiten, A. and K. Laland ‘Toward a unified science of cultural evolution’ [PDF]
, 2006 There is considerable scope for developing a more explicit role for ethnography within the research program proposed in the article. Ethnographic studies of cultural micro-evolution would complement experimental approaches by providing insights into the “

Red‐to‐Blue Upconversion Nanoparticles Catalyze Aqueous Radical Polymerization
Advanced Optical Materials, EarlyView.Encapsulation of a red‐to‐blue upconversion pair into polymer nanoparticles gives water‐stable heterogeneous nanocatalysts with distinguished stability. Red light irradiation of these nanocatalysts initiates aqueous polymerization of a series of acrylates with high conversion yields.

Probabilistic facial feature extraction using joint distribution of location and texture information [PDF]
, 2009 In this work, we propose a method which can extract critical points on a face using both location and texture information. This new approach can automatically learn feature information from training data.

Magnetic Field Driven Microrobot Based on Hydrogels
Advanced Robotics Research, EarlyView.Hydrogel‐based magnetic microrobots synergize remote magnetic control with the biocompatibility of flexible hydrogels, emerging as promising tools for minimally invasive biomedicine. This enables remotely controllable, untethered navigation within complex biological microenvironments.

Age Estimation Based on AAM and 2D-DCT Features of Facial Images
, 2015 This paper proposes a novel age estimation method - Global and Local feAture based Age estiMation (GLAAM) - relying on global and local features of facial images. Global features are obtained with Active Appearance Models (AAM).

Advanced Science, EarlyView.A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

An Opto‐Actuated Hydrogel for Cell Mechanoactuation and Real‐Time Force Monitoring
Advanced Science, EarlyView.Researchers developed a mechanoactuated hydrogel interface where nanomachines exert forces on adhesion receptors and allow monitoring of traction force responses in real time. They demonstrate reversible talin recruitment, enhanced F‐actin polymerization, and a reduction in cell traction force when force is locally applied to focal adhesions of ...
