Nature Photonics, 2010 Few-cycle light pulses are important for attosecond science and extremely nonlinear optics. Alfred Leitenstorfer from the University of Konstanz spoke to Nature Photonics about how erbium-doped fibre laser technology can generate single-cycle pulses at telecommunications wavelengths.

Clocks & SleepIndividuals with neurodevelopmental disorders (NDDs) often experience sleep disturbances and are frequently exposed to light during nighttime hours. Our previous studies using the Contactin-associated protein-like 2 (Cntnap2) knockout (KO) mouse model of

, 2022 The past decade has witnessed a sharp rise of interest in coherent terahertz (THz) light sources for applications in condensed-matter physics. These sources are a powerful tool for studying collective excitations in solid-state systems: THz light can directly couple to low-energy excitations on the meV-scale such as the collective excitations of spins ...

Heavy and Light Paths and Hamilton Cycles
SSRN Electronic Journal, 2022 Given a graph $G$, we denote by $f(G,u_0,k)$ the number of paths of length $k$ in $G$ starting from $u_0$. In graphs of maximum degree 3, with edge weights $i.i.d.$ with $exp(1)$, we provide a simple proof showing that (under the assumption that $f(G,u_0,k)=ω(1)$) the expected weight of the heaviest path of length $k$ in $G$ starting from $u_0$ is at ...

The Annual Cycling of Nighttime Lights in India [PDF]
Remote Sensing, 2021 India is known to have unstable power supply, and many locations show an annual cycle in VIIRS Nighttime Light (VNL). In this study, autocorrelation function (ACF) analysis is used to identify the annual cycling in VNL. Two fundamentally different classification techniques are proposed to classify the ACF profile into one of the three arch types, i.e.,

Towards single-cycle attosecond light from accelerators [PDF]
, 2019 The Free-Electron Laser (FEL) is a cutting-edge, accelerator-based instrument that has the potential to provide simultaneous access to the spatial and temporal resolution of the atomic world. In a FEL, ultra-short electron bunches from an accelerator are

Visual opsins: Physiological alteration promoted by led light
Journal of Photochemistry and Photobiology, 2023 Rods are the most sensitive cells to light present in the retina, being therefore responsible for dim light vision. Light photons captured by the retina stimulate rhodopsin, promoting phototransduction mechanisms that end up sending the information to ...

Light Regulates the Cell Cycle in Zebrafish [PDF]
Current Biology, 2003 The timing of cell proliferation is a key factor contributing to the regulation of normal growth. Daily rhythms of cell cycle progression have been documented in a wide range of organisms. However, little is known about how environmental, humoral, and cell-autonomous factors contribute to these rhythms.

On light cycles in plane triangulations
Discrete Mathematics, 1999 A graph \(H\) is said to be light in the class of graphs \({\mathcal G}\) if there exists a positive integer \(k\) such that each graph \(G\in{\mathcal G}\) that contains an isomorphic copy of \(H\) contains a subgraph \(K\) isomorphic to \(H\) that satisfies the inequality \(\deg_G(v)\leq k\), for all vertices \(v\) of \(K\).
