Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Novel hierarchical identity-based encryption scheme from lattice
Tongxin xuebao, 2017 Aiming at the high complexity in user’s private key extraction and large expansion ratio of trapdoor size in previous hierarchical identity-based encryption (HIBE) schemes,a new HIBE scheme was proposed.The implicit extension method to improve preimage ...

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions
FEBS Letters, EarlyView.Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Efficient identification protocol provably secure in standard model
Tongxin xuebao, 2009 Based on the hardness assumption of the collusion attack algorithm with k traitors （K-CAA） in a gap Diffie-Hellman （GDH） group, a new and efficient identification protocol is proposed.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Efficient chosen-ciphertext secure proxy re-encryption scheme
Tongxin xuebao, 2013 In order to construct an efficient and chosen-chiphertext secure unidirectional re-encryption scheme in the standard model,a novel and efficient unidirectional proxy re-encryption scheme was proposed, and its chosen-ciphertext security in the adaptive ...

Frontiers in Astronomy and Space SciencesIt is postulated that the energy density of the (quantum) vacuum acts firstly as dark energy and secondly as a part of dark matter. Assisted by electric fields arising from a small charge mismatch in the cosmic plasma, it can condense on mass ...
