Discrete Mathematics, 1991 A sequence \(a_ 0,\dots,a_ n\) is said to be log concave if \(a_{i- 1}a_{i+1}\leq a^ 2_ i\) for \(i=1,\dots,n-1\). In this note a log concave sequence is assumed to consist of positive real numbers. The main result of the authors shows how a log concave sequence generates a log supermodular function on the lattice \(\{(i,j)\mid\;0\leq i,j\leq n ...

In Situ Two‐Dimensional Residual Stress Characterization of Thin Films
Advanced Materials Technologies, EarlyView.An integrated in situ curvature metrology platform combining speckle‐based curvature optical metrology (SCOM) with multi‐beam optical sensors (MOS) enables spatially resolved two‐dimensional curvature mapping of thick sputtered coatings. The SCOM technique provides excellent agreement with MOS while providing an extended measurable curvature range ...

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract
Advanced Robotics Research, EarlyView.We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots
Advanced Robotics Research, EarlyView.This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

The Impact of Concave Coastline on Rainfall Offshore Distribution over Indonesian Maritime Continent
The Scientific World Journal, 2019 Indonesian Maritime Continent has the second longest coastline in the world, but the characteristics of offshore rainfall and its relation to coastline type are not clearly understood. As a region with eighty percent being an ocean, knowledge of offshore

Advanced Science, EarlyView.The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.
