Qualitative Sociology, 2022 The basic practice of ethnography has essentially remained unchanged in hundreds of years. How has online life changed things? I contrast two transformative inventions, the telephone and the internet, with respect to their impact on fieldwork. I argue that our current era has created entirely new constraints and opportunities for ethnographic research.

The Superhilac Upgrade Project [PDF]
IEEE Transactions on Nuclear Science, 1985 This project will increase the uranium output of the Bevalac heavy-ion facility from the currently available 107 to 5×107 ions/pulse, allowing accurate Lamb shift measurements to be made in U90+ and U91+ with important applications to the testing of quantum electrodynamics and the development of an x-ray laser.

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Multi-Range Sequential Learning Based Dark Image Enhancement with Color Upgradation
Applied Sciences, 2023 Images under low-light conditions suffer from noise, blurring, and low contrast, thus limiting the precise detection of objects. For this purpose, a novel method is introduced based on convolutional neural network (CNN) dual attention unit (DAU) and ...

Advanced Functional Materials, EarlyView.Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Advanced Healthcare Materials, EarlyView.This work introduces a “cancer‐in‐a‐well” technology that recreates tumor heterogeneity in vitro using multitype spheroid arrays. Combining bioprinting/microdispensing with microstructured culture devices, the system improves drug screening and modeling of tumor complexity.

Use of ultrasound in petroleum residue upgradation
, 2009 Conventional processes for the upgradation of residual feedstocks, viz., thermal cracking and catalytic cracking are carried out in the temperature range of 400-520°C. Such high temperatures can in principle be substituted by acoustic cavitation.
