Factor-4 and 6 compression of cyclotomic subgroups of and

Journal of Mathematical Cryptology, 2010
Bilinear pairings derived from supersingular elliptic curves of embedding degrees 4 and 6 over finite fields 𝔽2m and 𝔽3m, respectively, have been used to implement pairing-based cryptographic protocols.

Constructing suitable parameters for pairing-based cryptography [PDF]

, 2021
Οι ̔ ̔ζευγισμοί ̓ ̓ παρουσιάστηκαν για πρώτη φορά από τον André Weil το 1940 και αρχικά χρησιμοποιήθηκαν ως μηχανισμός επίθεσης στο πρόβλημα διακριτού λογάριθμου σε ελλειπτικές καμπύλες. Περίπου 60 χρόνια μετά την ανακάλυψή τους, οι ζευγισμοί έχουν γίνει ένα από τα σπουδαιότερα αντικείμενα μελέτης στην κρυπτογραφία. ́Ενα από σημαντικότερα προβλήματα σε

A survey of fault attacks in pairing based cryptography

Cryptography and Communications, 2014
The latest implementations of pairings allow efficient schemes for Pairing Based Cryptography. These make the use of pairings suitable for small and constrained devices (smart phones, smart cards…) in addition to more powerful platforms.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Acoustic Fingerprints for Access Management in Ad-Hoc Sensor Networks

IEEE Access, 2020
Voice user interfaces can offer intuitive interaction with our devices, but the usability and audio quality could be further improved if multiple devices could collaborate to provide a distributed voice user interface.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
