Comptonization, the X-ray-radio correlation and the long-term periodicity in the chi-states of GRS 1915+105 [PDF]
, 2002 We analyzed 139 chi-state observations of GRS 1915+105 with RXTE from 1997 to 2000 and found i) that the observations fall into two groups with different Comptonization behavior, ii) that the slope of the hard X-ray component correlates with the radio ...

Exploring DNA Functionalization Techniques for Silver Nanoparticles
Advanced Materials Interfaces, EarlyView.This study evaluates four functionalization methods—salt‐aging, pH‐assisted, freezing‐directed, and microwave‐assisted—for attaching DNA strands to 20 nm silver nanoparticles (AgNPs). The resulting DNA‐AgNP conjugates are characterized and colloidal stability and DNA loading are assessed.

Nonlinear estimation in turbulent channel flows [PDF]
arXivWe design a nonlinear estimator for channel flows at $Re_{\tau}=180$ and $590$. The nonlinear estimator uses a linear estimator structure based on the linearised Navier-Stokes equations and explicitly calculates the nonlinear forcing from the estimated velocities in physical space. The goal is to use the velocities at one wall-normal height to estimate

On the number of semi-magic squares of order 6 [PDF]
arXiv, 2018 We present an exact method for counting semi-magic squares of order 6. Some theoretical investigations about the number of them and a probabilistic method are presented. Our calculations show that there are exactly $94\,590\,660\,245\,399\,996\,601\,600$ such squares up to reflections and rotations.

Advanced Materials Interfaces, EarlyView.A novel class of thermo‐responsive surfactants is developed for stabilizing and on‐demand demulsifying water‐in‐oil droplets in microfluidic systems. These surfactants enable temperature‐triggered recovery of cell‐laden hydrogel microgels without chemical demulsifiers. The approach offers a biocompatible and scalable solution for applications in tissue
