Optical full Hadamard matrix multiplexing and noise effects: errata [PDF]

open access: yes, 2011
The model for Poisson random noise under Hadamard multiplexing is revised. The new model accounts for the variation of the Hadamard multiplexed measurements, as well as the previously considered variation due to Poisson fluctuations.

Robust dimethyl‐based multiplex‐DIA doubles single‐cell proteome depth via a reference channel

open access: yesMolecular Systems Biology, 2023
Single‐cell proteomics aims to characterize biological function and heterogeneity at the level of proteins in an unbiased manner. It is currently limited in proteomic depth, throughput, and robustness, which we address here by a streamlined multiplexed ...

Orbital Angular Momentum (OAM) Mode Mixing in a Bent Step Index Fiber in Perturbation Theory

open access: yesIEEE Photonics Journal, 2019
Within the framework of perturbation theory, we explore in detail the mixing of orbital angular momentum (OAM) modes due to a fiber bend in a step-index multimode fiber.

New multiplexing scheme for monitoring fiber optic Bragg grating sensors in the coherence domain

open access: yes, 1997
A new multiplexing scheme for monitoring fiber optic Bragg gratings in the coherence domain has been developed. Grating pairs with different grating distances are distributed along a fiber line, and interference between their reflections is monitored ...

Multiplexing MIM [PDF]

open access: yesDevelopmental Cell, 2010
Signaling circuits often coordinate cellular membranes and actin filaments at distinct sites to direct cell behavior. In this issue of Developmental Cell, Bershteyn et al. outline how the molecular scaffold protein, MIM, which bends membranes and binds actin filaments, is at the middle of one such circuit to regulate ciliogenesis.

Faces of a Changing Climate: Semi-Quantitative Multi-Mycotoxin Analysis of Grain Grown in Exceptional Climatic Conditions in Norway

open access: yesToxins, 2013
Recent climatological research predicts a significantly wetter climate in Southern Norway as a result of global warming. Thus, the country has already experienced unusually wet summer seasons in the last three years (2010–2012).
