Decoupling Fabrication From Encoding: DNA‐Addressable Template Microparticles for Large, User‐Defined Optical Barcode Libraries

Advanced Science, EarlyView.
A universal hydrogel microparticle template with five DNA‐addressable domains decouples particle fabrication from barcode writing. Contact‐free multilaminar flow lithography produces >106 templates/h, and post‐fabrication domain‐selective hybridization converts one batch into large, user‐defined optical barcode libraries with robust decoding and re ...

A Review of Techniques for Implementing Elliptic Curve Point Multiplication on Hardware

Journal of Sensor and Actuator Networks, 2020
Cryptography is considered indispensable among security measures applied to data concerning insecure means of transmission. Among various existent algorithms on asymmetric cryptography, we may cite Elliptic Curve Cryptography (ECC), which has been widely

TECTB Variants Reveal Tectorial Membrane Vulnerability in Dominant Non‐Syndromic Hearing Loss

Advanced Science, EarlyView.
TECTB is a non‐collagenous protein of the tectorial membrane – an extracellular matrix of the cochlea. This study identifies dominant missense variants in TECTB linked to human hereditary deafness in two unrelated families. Genetically engineered mice homozygous for one of the variants are profoundly deaf, whereas heterozygous mice have normal hearing ...

Fast Programming of in‐Plane Hyperbolic Phonon Polariton Optics through Van der Waals Crystals Using the Phase‐Change Material In3SbTe2

Advanced Science, EarlyView.
Launching structures for in‐plane hyperbolic polaritons in α‐MoO3 are optically programmed through already deposited flakes into the phase‐change material In3SbTe2. Precise alignment with the flake's crystal axes, focusing of polaritons by an optically programmed disk, and a first experimental realization toward a nanocavity for in‐plane hyperbolic ...

Reversible, Chemically Gated FRET via Ligand‐Activated Acceptors

Advanced Science, EarlyView.
Fluorogen binding turns the compact FAST tag into a tunable FRET acceptor, with ligand chemistry programming spectral overlap and excited‐state lifetimes. Fluorescence‐lifetime imaging reads out energy transfer through the shortened donor lifetime, while simply adding or washing out the dye switches FRET on and off, reversibly mapping the supramodular ...

Phase-Image-Encryption-Based Elliptic Curve and Double-Random-Phase Encoding

Engineering Proceedings
In this paper, we proposed an enhanced asymmetric cryptosystem scheme for image encryption using a combination of Elliptic Curve and Fourier transformations. Our proposed encryption and decryption process is highly secure with a smaller key size compared

Multimodal Imaging of Hypoxia, Metabolism and pH in Feline Sarcoma Using Hyperpolarized 13C MRI and PET

Advanced Science, EarlyView.
This work presents a clinically deployable simultaneous PET/MRI workflow which integrates hyperpolarized 13C imaging of metabolism and extracellular pH with [18F]FMISO PET to characterize hypoxia, acidosis, and metabolic reprogramming in feline sarcoma.

SE-Enc: A Secure and Efficient Encoding Scheme Using Elliptic Curve Cryptography

IEEE Access, 2019
Many applications use asymmetric cryptography to secure communications between two parties. One of the main issues with asymmetric cryptography is the need for vast amounts of computation and storage.

IMPLEMENTATION OF BLOM’S KEY PREDISTRIBUTION SCHEME BY USING ELLIPTIC CURVE CRYPTOGRAPHY

Malaysian Journal of Computing, 2021
Cryptography, along with its various methods is used to serve the security communication purpose. Cryptography is said to be secure if the encryption key is hard to break by the attacker.
