CoRR, 2020 Deep neural networks have become remarkably good at producing realistic deepfakes, images of people that (to the untrained eye) are indistinguishable from real images. Deepfakes are produced by algorithms that learn to distinguish between real and fake images and are optimised to generate samples that the system deems realistic.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Cladding-pumped Raman fiber with a W-type core designed for power scaling
, 2009 We design a cladding-pumped fiber Raman amplifier with a wavelength-filtering W-type core for the suppression of the 2nd-order Raman Stokes.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Intrinsic multichannel power control in cascaded power-equalizing erbium-doped fiber amplifiers [PDF]
, 2000 We numerically investigate the performance of a cascade of four-channel power-equalizing reflective erbium-doped fiber amplifiers (EDFAs). The EDFAs reflect different channels at different points so that different channels interact with partly different ...

A Micropower Electrocardiogram Amplifier [PDF]
IEEE Transactions on Biomedical Circuits and Systems, 2009 We introduce an electrocardiogram (EKG) preamplifier with a power consumption of 2.8 muW, 8.1 muVrms input-referred noise, and a common-mode rejection ratio of 90 dB. Compared to previously reported work, this amplifier represents a significant reduction in power with little compromise in signal quality. The improvement in performance may be attributed

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Tunable single-frequency ytterbium-sensitized erbium-doped fiber MOPA source with 150W (51.8 dBm) of output power at 1563 nm [PDF]
, 2005 A single-frequency, single-mode ytterbium-sensitized erbium-doped fiber master-oscillator power-amplifier generated 150 W of continuous-wave output power at 1563 nm with 33% slope efficiency and was tuned in the range of 1546 to 1566 nm at >125 ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
