Emerging strategies to target metastasis and therapy resistance in melanoma

Molecular Oncology, EarlyView.
Emerging studies propose new approaches to interfere with melanoma progression. In recognition of melanoma awareness month, at Molecular Oncology, we highlight recently published research articles, focusing on novel therapeutic targets driving metastatic spread and outlining different strategies to overcome resistance to BRAF inhibitors and anti‐PD‐1 ...

Miniature photonic-crystal hydrophone optimized for ocean acoustics

, 2010
This work reports on an optical hydrophone that is insensitive to hydrostatic pressure, yet capable of measuring acoustic pressures as low as the background noise in the ocean in a frequency range of 1 Hz to 100 kHz.

Influence of phase optic sensor to the DWDM network [PDF]

, 2015
This article deals with influence of phase optic sensor to the DWDM transmission. In DWDM network we use four lasers sources for data transmission on one optical fiber. Next one DFB laser is used for phase optical sensor on the same optical fiber.

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

Advanced Engineering Materials, EarlyView.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.
