Lovász-Schrijver PSD-operator on Claw-Free Graphs [PDF]
arXiv, 2016 The subject of this work is the study of $\LS_+$-perfect graphs defined as those graphs $G$ for which the stable set polytope $\stab(G)$ is achieved in one iteration of Lov\'asz-Schrijver PSD-operator $\LS_+$, applied to its edge relaxation $\estab(G)$. In particular, we look for a polyhedral relaxation of $\stab(G)$ that coincides with $\LS_+(\estab(G)

Advanced Materials Interfaces, EarlyView.This study introduces an approach for creating liquid‐like slippery surfaces (LLS) on various substrates. An epoxy‐silicon (EpSi) coating is applied, plasma‐activated, and immersed in an organosilane solution, forming siloxane chains. The resulting LLS exhibits ultra‐low ice adhesion, high transparency, self‐cleaning, and anti‐staining properties ...

Flow physics of planar bistable fluidic oscillator with backflow limbs
AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract Fluidic oscillators (FOs) are used in a variety of applications, including process control and process intensification. Despite the simple design and operation of FOs, the fluid dynamics of FOs exhibit rich complexities. The inherently unstable flow, jet oscillations, and resulting vortices influence mixing and other transport processes.

Orthogonal Point Location and Rectangle Stabbing Queries in 3-d [PDF]
arXiv, 2018 In this work, we present a collection of new results on two fundamental problems in geometric data structures: orthogonal point location and rectangle stabbing. -We give the first linear-space data structure that supports 3-d point location queries on $n$ disjoint axis-aligned boxes with optimal $O\left( \log n\right)$ query time in the (arithmetic ...

AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract Lignin‐rich stream from lignocellulosic ethanol production was converted into biocrude by continuous hydrothermal liquefaction (HTL) while hydrogen was produced by aqueous phase reforming (APR) of the HTL aqueous by‐product. The effects of Na2CO3 and NaOH were investigated both in terms of processability of the feedstock as well as yield and ...

Stabbing Rectangles by Line Segments - How Decomposition Reduces the Shallow-Cell Complexity [PDF]
arXiv, 2018 We initiate the study of the following natural geometric optimization problem. The input is a set of axis-aligned rectangles in the plane. The objective is to find a set of horizontal line segments of minimum total length so that every rectangle is stabbed by some line segment.

Advanced Materials Interfaces, EarlyView.In this work, wide‐field (>1 mm2) frequency‐domain thermoreflectance (FDTR) hyperspectral imaging is used to image subsurface indium bump bonds 50 µm below the surface. Thermal analysis with Monte Carlo uncertainty propagation is used to evaluate bump quality, while a trained deep neural network (can rapidly reconstruct bump geometry contact area maps.
