All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

open access: yesAdvanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

The Development of Grain Farming

Problems in Economics, 1984
The task of grain farming is to satisfy the country's ever greater needs for high-quality food and fodder grain, to create necessary state grain reserves, and to provide reserves for its export. These tasks can be achieved by increasing the gross harvest through higher yields; making better use of resources; securing the harvest against loss to the ...

Development of Grain Avalanches

Physical Review Letters, 2002
We present a new theoretical approach aimed to describe the dynamical properties of avalanches. Starting from simple microscopic considerations, we propose an analytical derivation accounting for the avalanche growth as a function of time. The solution resembles very closely recent experimental observations.

Albumins and globulins in developing maize grains

Biochimie, 1987
Quantitative and qualitative (amino acid composition) changes of albumins and globulins in developing grain of normal and opaque-2 (o2) maizes were examined in proteins extracted sequentially with water and 0.5 M NaCl, and isolated by salting out with trichloroacetic acid.

Structure and development of cereal grains

2023
The grains of cereals are single-seeded fruit. They have similar patterns of development with the mature grain being composed of the triploid endosperm tissue and diploid embryo surrounded by tissues of maternal origin, notably the testa (seed coat) and pericarp (fruit coat). The embryo comprises the embryonic axis (which develops to form the seedling)

The inheritance of ?-amylases in developing barley grain

Biochemical Genetics, 1973
Three types of β-amylase isozyme pattern (Sdd, Sde, and Sdf) were observed in the doughy endosperm stage of ripening barley grains. From crosses between Sdd and Sdf types, it was concluded that these phenotypes are controlled by a pair of codominant alleles.
