Adaptive Secret Sharing for Color Images [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2011
A secret sharing model can secure a secret over multiple noise-like shadows and remain recoverable despite multiple shadow failures. Even if some of the shadows are compromised, the secret will not be revealed as long as the number of the compromised ...

The data shadow

open access: yesACM SIGCAS Computers and Society, 2017
This hypothetical story is about personal data which resides on the internet. It has its foundation in things which have happened. It raises serious questions about whether we should be more wary of, and whether there are things organisations and individuals could do to reduce the risks associated with data shadows.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Robust tracking of multiple objects in video by adaptive fusion of subband particle filters

open access: yesIET Computer Vision, 2018
Tracking of moving objects in video sequences is an important research problem because of its many industrial, biomedical, and security applications. Significant progress has been made on this topic in the last few decades.

Painting, science, and the perception of coloured shadows : the most beautiful blue

open access: yes, 2021
Many artists and scientists – including Buffon, Goethe, and Philipp Otto Runge – who observed the vividly coloured shadows that appear outdoors around dawn and dusk, or indoors when a candle burns under waning daylight, chose to describe their colours as

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Climbing shadows poems for children

open access: yes, 2019
"The poems in Climbing Shadows were inspired by a class of kindergarten children whom poet and playwright Shannon Bramer came to know over the course of a school year. She set out to write a poem for each child, sharing her love of poetry with them. This

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
