Shift in the Light Quality of Night Interruption Affects Flowering and Morphogenesis of Petunia hybrida

open access: yesPlants, 2023
Petunia hybrida Hort. “Easy Wave Pink”, a qualitative long-day plant (LDP), was investigated to study the effects of the night interruption light (NIL) provided by light-emitting diodes (LEDs) quality shifting on the morphogenesis, blooming, and ...

Dual-Wavelength Terahertz Metasurfaces with Independent Phase and Amplitude Control at Each Wavelength

open access: yesScientific Reports, 2016
We have designed, fabricated and characterized dual-wavelength metasurfaces that function at two assigned terahertz wavelengths with independent phase and amplitude control at each wavelength.

Olaparib synergy screen reveals Exemestane induces replication stress in triple‐negative breast cancer

open access: yesMolecular Oncology, EarlyView.
Screening 166 FDA‐approved anticancer drugs identifies the aromatase inhibitor Exemestane as a synergistic partner of PARP inhibitor Olaparib in BRCA‐proficient triple‐negative breast cancer. Exemestane induces ROS‐mediated replication stress, enhancing DNA damage and apoptosis alongside Olaparib.

A Quantum Yield Map for Synthetic Eumelanin [PDF]

open access: yes, 2005
The quantum yield of synthetic eumelanin is known to be extremely low and it has recently been reported to be dependent on excitation wavelength. In this paper, we present quantum yield as a function of excitation wavelength between 250 and 500 nm ...

A Machine Learning Specklegram Wavemeter (MaSWave) Based on a Short Section of Multimode Fiber as the Dispersive Element

open access: yesSensors, 2023
Wavemeters are very important for precise and accurate measurements of both pulses and continuous-wave optical sources. Conventional wavemeters employ gratings, prisms, and other wavelength-sensitive devices in their design.

Wavelength-multiplexed quantum networks with ultrafast frequency combs [PDF]

open access: yesNature Photonics, 2013
Highly entangled quantum networks (cluster states) lie at the heart of recent approaches to quantum computing1,2. Yet the current approach for constructing optical quantum networks does so one node at a time3,4,5, which lacks scalability.

Understanding and measuring mechanical signals in the tumor stroma

open access: yesFEBS Open Bio, EarlyView.
This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

Effect of wavelength dependence of nonlinearity, gain, and dispersion in photonic crystal fiber amplifiers

open access: yes, 2005
Photonic crystal fibers are used in fiber amplifiers and lasers because of the flexibility in the design of mode area and dispersion. However, these quantities depend strongly on the wavelength.

Ultrafast wavelength jumping and wavelength adjustment with low current using monolithically integrated FML for long-reach UDWDM-PON [PDF]

open access: yes, 2016
Ultrafast wavelength jumping at optical network units (ONUs) for an access network with frequency modulated lasers (FMLs) is demonstrated. This FML consists of an intracavity tunable phase section and filtering gain section. It provides a total of 4.2 nm

Impact of optical wavelength on the reliability of photoplethysmography-based heart rate measurements outside of controlled laboratory environments

open access: yesCurrent Issues in Sport Science
Introduction The effectiveness of heart rate (HR) measurements via photoplethysmography (PPG) depends on the wavelength of light used. Typical PPG sensors use green, red, or infrared light, each penetrating the skin to different depths (Ray et al ...
