3D molecular phenotyping of cleared human brain tissues with light-sheet fluorescence microscopy
Communications Biology, 2022 An optimized clearing approach, named SHORT, applied to thick sections of human cortical tissue allows reconstruction of large portions of the tissues using light-sheet fluorescence microscopy, by performing multicolor immunostaining and multirounds.

Nature Communications, 2022 By using laser tweezers, the authors show that a single α-catenin molecule does not resist force on F-actin. However, clustering of multiple molecules and force applied toward F-actin pointed end engage a molecular switch in α-catenin, which unfolds and ...

Assessing brain state and anesthesia level with two-photon calcium signals
Scientific Reports, 2023 Brain states, such as wake, sleep, or different depths of anesthesia are usually assessed using electrophysiological techniques, such as the local field potential (LFP) or the electroencephalogram (EEG), which are ideal signals for detecting activity ...

Theory and Applications of Categories, 2022 In 2017, Bauer, Johnson, Osborne, Riehl, and Tebbe (BJORT) showed that the Abelian functor calculus provides an example of a Cartesian differential category. The definition of a Cartesian differential category is based on a differential combinator which directly formalizes the total derivative from multivariable calculus. However, in the aforementioned

Radiative corrections to the semileptonic and hadronic Higgs-boson decays H -> W W/Z Z -> 4 fermions [PDF]
, 2006 The radiative corrections of the strong and electroweak interactions are calculated for the Higgs-boson decays H -> WW/ZZ -> 4f with semileptonic or hadronic four-fermion final states in next-to-leading order. This calculation is improved by higher-order

Procedural embodiment and magic in linear equations [PDF]
, 2008 How do students think about algebra? Here we consider a theoretical framework which builds from natural human functioning in terms of embodiment – perceiving the world, acting on it and reflecting on the effect of the actions – to shift to the use of ...

Autofluorescence enhancement for label-free imaging of myelinated fibers in mammalian brains
Scientific Reports, 2021 Analyzing the structure of neuronal fibers with single axon resolution in large volumes is a challenge in connectomics. Different technologies try to address this goal; however, they are limited either by the ineffective labeling of the fibers or in the ...

A Linear Network Code Construction for General Integer Connections Based on the Constraint Satisfaction Problem [PDF]
, 2015 The problem of finding network codes for general connections is inherently difficult in capacity constrained networks. Resource minimization for general connections with network coding is further complicated.
