In Search of the Module in the Architectural Design of the ‘Hellenistic’ House in Nea Paphos, Cyprus

Études et Travaux (Institute des Cultures Méditerranéennes et Orientales de l'Académie Polonaise des Sciences), 2021
Ancient Graeco-Roman architecture was designed with the application of mathematical harmony as a key compositional principle used in planning the dimensions and proportions of particular elements, larger parts of buildings or whole edifices.

GRAVITY: the Calibration Unit

, 2014
We present in this paper the design and characterisation of a new sub-system of the VLTI 2nd generation instrument GRAVITY: the Calibration Unit. The Calibration Unit provides all functions to test and calibrate the beam combiner instrument: it creates ...

State-of-the-art active optical techniques for three-dimensional surface metrology: a review [Invited].

Journal of The Optical Society of America A-optics Image Science and Vision, 2020
This paper reviews recent developments of non-contact three-dimensional (3D) surface metrology using an active structured optical probe. We focus primarily on those active non-contact 3D surface measurement techniques that could be applicable to the ...

Vectorial Doppler metrology

Nature Communications, 2021
The Doppler effect is a universal wave phenomenon that has spurred a myriad of applications. In early manifestations, it was implemented by interference with a reference wave to infer linear velocities along the direction of motion, and more recently ...

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties

Advanced Functional Materials, EarlyView.
High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

Spin squeezing, entanglement and quantum metrology with Bose-Einstein condensates

, 2012
Squeezed states, a special kind of entangled states, are known as a useful resource for quantum metrology. In interferometric sensors they allow to overcome the "classical" projection noise limit stemming from the independent nature of the individual ...

Heisenberg Limit Superradiant Superresolving Metrology [PDF]

, 2014
We propose a superradiant metrology technique to achieve the Heisenberg limit super-resolving displacement measurement by encoding multiple light momenta into a three-level atomic ensemble.

Overcoming Debye Length Limitations in Electrolyte‐Gated Transistor Biosensors Using Nanoscale‐Grooved Oxide Semiconductors Fabricated by Thermal Nanoimprint Lithography

Advanced Functional Materials, EarlyView.
Nanoscale‐grooved indium gallium oxide (IGO) semiconductors, patterned via thermal nanoimprint lithography (NIL) using CD/DVD templates, are integrated into electrolyte‐gated transistor biosensors to overcome Debye length limitations. Precisely engineered concave–convex nanostructures modulate local electrostatic potentials, extend the effective Debye ...
