Fiber-Based SERS-Fluidic Polymeric Platforms for Improved Optical Analysis of Liquids
Bioengineering, 2023 Downsizing surface-enhanced Raman spectroscopy (SERS) within microfluidic devices has opened interesting perspectives for the development of low-cost and portable (bio)sensors for the optical analysis of liquid samples. Despite the research efforts, SERS-

A Perfect Lens for Ballistic Electrons: A Kane's Model [PDF]
Photonics and Nanostructures - Fundamentals and Applications 12,
pp. 9-15, 2014, 2013 The analogy between electromagnetic waves and ballistic electrons within the Kane's model is developed and subsequently applied to a theoretical description of a quantum version of a metamaterial planar lens. Restrictions imposed on the perfect lens and the poor man's lens by available semiconductor band structures are discussed.

Sharing the burden : on the division of parental care and vocalizations during incubation [PDF]
, 2019 In species with biparental care, individuals only have to pay the costs for their own parental investment, whereas the contribution of their partner comes for free. Each parent hence benefits if its partner works harder, creating an evolutionary conflict

Lens coloboma treated with lens surgery [PDF]
BMJ Case Reports, 2015 A 5-year-old boy was referred to our clinic due to an abnormal visual acuity test at school. His corrected visual acuity was counting fingers in the left eye. A nasal side deficiency of the lens substituted by a membrane was found. Lens coloboma was diagnosed. After making a 3 mm limbal incision, the colobomatous lens was removed by anterior continuous

Strong Noise Rejection in VLC Links under Realistic Conditions through a Real-Time SDR Front-End
Sensors, 2023 One of the main challenges in the deployment of visible light communication (VLC) in realistic application fields, such as intelligent transportation systems (ITSs), is represented by the presence of large background noise levels on top of the optical ...

Differentiation state-specific mitochondrial dynamic regulatory networks are revealed by global transcriptional analysis of the developing chicken lens. [PDF]
, 2014 The mature eye lens contains a surface layer of epithelial cells called the lens epithelium that requires a functional mitochondrial population to maintain the homeostasis and transparency of the entire lens.
