Investigating the cell of origin and novel molecular targets in Merkel cell carcinoma: a historic misnomer

open access: yesMolecular Oncology, EarlyView.
This study indicates that Merkel cell carcinoma (MCC) does not originate from Merkel cells, and identifies gene, protein & cellular expression of immune‐linked and neuroendocrine markers in primary and metastatic Merkel cell carcinoma (MCC) tumor samples, linked to Merkel cell polyomavirus (MCPyV) status, with enrichment of B‐cell and other immune cell

Multi‐Level Electro‐Thermal Switching of Optical Phase‐Change Materials Using Graphene [PDF]

open access: yes, 2020
Reconfigurable photonic systems featuring minimal power consumption are crucial for integrated optical devices in real-world technology. Current active devices available in foundries, however, use volatile methods to modulate light, requiring a constant ...

Multistage optical switching networks

open access: yesJournal of Telecommunications and Information Technology, 2002
The backbone networks evolution to high-speed DWDM networks generates new problems for switching. This function element must be also based on optical technology.

Directional optical switching and transistor functionality using optical parametric oscillation in a spinor polariton fluid

open access: yes, 2017
Over the past decade, spontaneously emerging patterns in the density of polaritons in semiconductor microcavities were found to be a promising candidate for all-optical switching.

Two-photon absorption in microcavities for optical autocorrelation and sampling [PDF]

open access: yes, 2003
We have designed novel semiconductor microcavity structures for the enhancement of the two-photon absorption (TPA) photocurrent. We report a TPA autocorrelation technique for short optical pulses that uses the microcavity structure instead of a second ...

LIQUID CRYSTAL BASED OPTICAL SWITCHES [PDF]

open access: yesMolecular Crystals and Liquid Crystals, 2004
Optical switches using two electro-optical effects in liquid crystals are proposed and investigated for incorporation in a switch matrix for optical networks. These two devices employ selective reflection in cholesteric layers and total reflection at the border between glass and nematic liquid crystal.

Class IIa HDACs forced degradation allows resensitization of oxaliplatin‐resistant FBXW7‐mutated colorectal cancer

open access: yesMolecular Oncology, EarlyView.
HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

An ultra fast optical header replacement technology and its application for broadband optical packet switch. [PDF]

open access: yes, 2001
An optical header replacement technology based on Self Electro-optic Effect Devices (SEEDs) is presented. By using the measurement result of a 75 μm long SEED device, we simulate an 8 Gbps throughput is achievable.
