Lattice Resonances in Periodic Arrays of Time‐Modulated Scatterers

Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
This work explores how periodic time modulation alters the collective optical behavior of periodic arrays of scatterers, shedding light on the critical role of collective effects in time‐varying photonic systems and unveiling new opportunities for amplification, active control, and nonreciprocal functionalities.

Mechanical Impedance Matching Using a Magnetic Linear Gear

Shock and Vibration, Volume 2017, Issue 1, 2017., 2017
As part of the Fp7 Clean Sky Project, a linear magnetic gear prototype, called Z‐transmitter, for aerospace application was designed, built, and tested. It demonstrates a maximum force capacity of 4700 N at 25°C and 4500 N at 90°C. Force ratio between slow and fast stages remains constant and equal to the design value: 7.0.

Wavelength‐Dependent Differential Amplification of Raman Scattering by Chiral Gold Nanorods for Multiplexed Encoding

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
The SERS spectra of reporter molecules adsorbed on chiral gold nanorods depends on the handedness of circularly polarized light (CPL‐SERS). The bisignate plasmonic CD spectra of chiral nanorods provides wavelength‐dependent CPL‐SERS. Selective discrimination of chiral nanorod handedness and different Raman reporters allow highly sensitive codification ...

Keyholes in MIMO‐OFDM: Train‐to‐Wayside Communications in Railway Tunnels

Wireless Communications and Mobile Computing, Volume 2017, Issue 1, 2017., 2017
One of the key challenges in railway engineering is how to provide passengers an efficient, secure, and safe service. To achieve this, operators and stakeholders demand robust and high‐capacity train‐to‐wayside broadband radio. Current radio technologies implement MIMO (Multiple‐Input Multiple‐Output) technology, whose use requires a good ...

Tailoring Chiral Gold Nanorods via Single‐Step Seed‐to‐Au(III) Ratio and Unlocking their Potential in Refractive Index Sensing

Advanced Optical Materials, Volume 13, Issue 34, December 2, 2025.
A single‐step tunable chiral growth of Au NRs with controllable circular dichrosim (CD) response is reported, and the application of narrow CD response for biosensing with superior Figures of Merit (FoM = RIS/linewidth) over conventional extinction‐based approach in sensitivity is demonstrated.

A Study of the Far Infrared Spectrum of N‐Acetyl‐D‐Glucosamine Using THz‐TDS, FTIR, and Semiempirical Quantum Chemistry Methods

Journal of Spectroscopy, Volume 2016, Issue 1, 2016., 2016
The far infrared spectrum of N‐acetyl‐D‐glucosamine has been studied by combining THz–TDS and FTIR characterization techniques with theoretical studies based on semiempirical quantum chemistry methods. A strong spectral peak at 60 cm−1 has been identified, which constitutes the main signature of the material in the terahertz band.

RNN‐DAS: A New Deep Learning Approach for Detection and Real‐Time Monitoring of Volcano‐Tectonic Events Using Distributed Acoustic Sensing

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract We present a novel Deep Learning model based on recurrent neural networks (RNNs) with long short‐term memory (LSTM) cells, designed as a real‐time volcano‐seismic signal recognition system for distributed acoustic sensing (DAS) measurements. The model was trained on an extensive database of volcano‐tectonic events derived from the co‐eruptive ...

Weighted Least Squares Based Detail Enhanced Exposure Fusion

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
Many recent computational photography techniques play a significant role to avoid limitation of standard digital cameras to handle wide dynamic range of the real‐world scenes, containing brightly and poorly illuminated areas. In many of these techniques, it is often desirable to fuse details from images captured at different exposure settings, while ...
