How to Navigate in Different Environments and Situations: Lessons From Ants
Frontiers in Psychology, 2018 Ants are a globally distributed insect family whose members have adapted to live in a wide range of different environments and ecological niches. Foraging ants everywhere face the recurring challenge of navigating to find food and to bring it back to the

Characterization of image sets: the Galois Lattice approach [PDF]
, 2003 This paper presents a new method for supervised image classification. One or several landmarks are attached to each class, with the intention of characterizing it and discriminating it from the other classes.

DEL‐1 is an Endogenous Senolytic Protein that Inhibits Senescence‐Associated Bone Loss
Advanced Science, EarlyView.Senescent bone marrow stromal cells accumulate in the aging bone microenvironment, promoting bone degeneration. DEL‐1, an endogenous secreted protein, acts as a natural senolytic that selectively eliminates these cells. By engaging a β3 integrin/CD73/adenosine/p38 MAPK/BCL‐2 pathway, DEL‐1 counters aging‐related bone loss, revealing promising ...

Towards a Landmark-Based Pedestrian Navigation Service Using OSM Data
ISPRS International Journal of Geo-Information, 2017 With the advent of location-aware smartphones, the desire for pedestrian-based navigation services has increased. Unlike car-based services where instructions generally are comprised of distance and road names, pedestrian instructions should instead ...

Advanced Science, EarlyView.Polycarbonate nanogels enable lipid‐free delivery of anti‐MFAP‐5 siRNA into cancer‐associated fibroblasts (CAF) in hepatocellular carcinoma. In a cirrhotic murine model, this approach silences MFAP‐5, reduces fibroblast activation, and suppresses tumor growth by inhibiting NOTCH/Hes1‐driven angiogenesis. CAF‐targeted MFAP‐5 RNAi and conserved signaling

Precision Editing of NLRS Improves Effector Recognition for Enhanced Disease Resistance
Advanced Science, EarlyView.Precision engineering of plant NLR immune receptors enables rational design of enhanced pathogen resistance through mismatched pairing, domain swapping, and targeted mutagenesis. These approaches achieve multi‐fold expansion in recognition breadth while minimizing autoimmunity risks and fitness penalties.

Influence of Landmarks on Wayfinding and Brain Connectivity in Immersive Virtual Reality Environment
Frontiers in Psychology, 2017 Spatial navigation is influenced by landmarks, which are prominent visual features in the environment. Although previous research has focused on finding advantages of landmarks on wayfinding via experimentation; however, less attention has been given to ...
