Like apoptosis, oncogene-induced senescence is a barrier to tumor development. However, relatively little is known about the signaling pathways mediating the senescence response. p38-regulated/activated protein kinase (PRAK) is a p38 MAPK substrate whose physiological functions are poorly understood. Here we describe a role for PRAK in tumor suppression by(More)
Semiconductor p-n junctions are essential building blocks for electronic and optoelectronic devices. In conventional p-n junctions, regions depleted of free charge carriers form on either side of the junction, generating built-in potentials associated with uncompensated dopant atoms. Carrier transport across the junction occurs by diffusion and drift(More)
We have experimentally determined the energies of the ground and first four excited excitonic states of the fundamental optical transition in monolayer WS_{2}, a model system for the growing class of atomically thin two-dimensional semiconductor crystals. From the spectra, we establish a large exciton binding energy of 0.32 eV and a pronounced deviation(More)
With the coming era of Big Data, hardware implementation of machine learning has become attractive for many applications, such as real-time object recognition and face recognition. The implementation of machine learning algorithms needs intensive memory access, and SRAM is critical for the overall performance. This paper proposes a new design of high speed(More)
Touchscreen technology plays an important role in the booming mobile devices market. Traditional touchscreen only provides 2D interactions with limited user experience. To overcome these limitations, we propose a novel 3D touch sensing system called the Airtouch system, which can recognize the movement of the finger in a 3-dimensional space. Half of the(More)
We report the results of systematic studies of plasmonic and photonic guided modes in large-area single-layer graphene integrated into a nanostructured silicon substrate. The interaction of light with graphene and substrate photonic crystals can be classified in distinct regimes depending on the relation of the photonic crystal lattice constant and the(More)
