Combined laser-based X-ray fluorescence and particle-induced X-ray emission for versatile multi-element analysis

open access: yesScientific Reports, 2021
Particle and radiation sources are widely employed in manifold applications. In the last decades, the upcoming of versatile, energetic, high-brilliance laser-based sources, as produced by intense laser–matter interactions, has introduced utilization of ...

Linearizing Nonlinear Optics [PDF]

open access: yesEPJ Web of Conferences, 2019
Fourier nonlinear optics merges the simplicity of linear optics with the power of nonlinear optics to achieve a decoupling of frequencies, amplitudes and phases in nonlinear processes - enabling first deep UV shaping at 207nm.

Withania somnifera Root Extract Inhibits Mammary Cancer Metastasis and Epithelial to Mesenchymal Transition [PDF]

open access: yes, 2013
Though clinicians can predict which patients are at risk for developing metastases, traditional therapies often prove ineffective and metastatic disease is the primary cause of cancer patient death; therefore, there is a need to develop anti-metastatic ...

Peak power & average power scaling via fourier domain OPA (FOPA) [PDF]

open access: yesEPJ Web of Conferences, 2019
FoTaking advantage of pulse shortening upon amplification, we demonstrate 2.5TW pulses (30mJ, 2 cycle, 1.8 μm) based on TiSa pumping, while for boosting average power we utilize a 500W Yb platform for pump and seed pulses.

Enhanced laser-driven proton acceleration using nanowire targets

open access: yesScientific Reports, 2021
Laser-driven proton acceleration is a growing field of interest in the high-power laser community. One of the big challenges related to the most routinely used laser-driven ion acceleration mechanism, Target-Normal Sheath Acceleration (TNSA), is to ...

Homodyne Solid-State Biased Coherent Detection of Ultra-Broadband Terahertz Pulses with Static Electric Fields

open access: yesNanomaterials, 2021
We present an innovative implementation of the solid-state-biased coherent detection (SSBCD) technique, which we have recently introduced for the reconstruction of both amplitude and phase of ultra-broadband terahertz pulses.

Full recovery of ultrafast waveforms lost under noise

open access: yesNature Communications, 2021
Extracting weak, ultrafast single-shot waveforms from a noisy background has critical uses in many applications. Here, the authors present a method to enhance signals and recover arbitrary waveforms from very noisy backgrounds by manipulating the ...

Downregulation of 26S proteasome catalytic activity promotes epithelial-mesenchymal transition. [PDF]

open access: yes, 2016
The epithelial-mesenchymal transition (EMT) endows carcinoma cells with phenotypic plasticity that can facilitate the formation of cancer stem cells (CSCs) and contribute to the metastatic cascade.

Environment-Aware Knowledge Distillation for Improved Resource-Constrained Edge Speech Recognition

open access: yesApplied Sciences, 2023
Recent advances in self-supervised learning have allowed automatic speech recognition (ASR) systems to achieve state-of-the-art (SOTA) word error rates (WER) while requiring only a fraction of the labeled data needed by its predecessors. Notwithstanding,
