High dynamic range imaging

Roku has just released an entirely new fleet of streaming devices. These five new Roku Streaming devices will replace the previous Roku 1, 2, 3, and 4. The Roku Streaming Stick will continue to be the companies "portable offering." The new Roku players are broken down into three tiers. The top tier device is the Roku Ultra. The middle-tier streamers consist of the Roku Premier and Premier+. Rounding out the new devices in the entry level tier are the Roku Express and Express+. Roku has not only unleashed a deluge of streaming devices, but also some new functionality available in the Roku operating System. Furthermore, two of the devices support High Dynamic Range (HDR) video on HDR compatible TV 's. You can read about HDR video in this article,…

binding atoms to form molecules. The structural change of molecule is triggered by motion of electrons in the chemical bonds. Controlling this fast electron motion, in turn, allows to control the molecular structure change. Additionally, the ability to take snapshots of the electron motion dynamics will improve our…

Yongxin Zhao’s unique scientific contributions I have developed several enabling tools for optical imaging of biological systems, which are under two main themes: 1. Optogenetic indicators for neuronal activities; 2. Expansion Pathology, a novel imaging strategy for super-resolution imaging of archived clinical samples. For theme 1, I worked on optogenetic indicators for Ca2+ and voltage, two of the most significant types in neuroscience. I tackled the well-known challenge of engineering these…

diseases as it was known that some diseases change the mechanical properties of the tissues. This change results in increase in stiffness or elastic modulus of the tissue. Hence this phenomenon is the basis of Elastography imaging which depends on the mechanical properties of the tissue [1, 2]. There are three types of elastic modulus namely 1. Young’s Modulus denoted by E - It is the tendency of the object to deform along the axis when the opposing forces are applying along that axis. It…

Ultrafast Electron Microscopy has been demonstrated to be an effective table-top technique for imaging the temporally-evolving dynamics of matter with subparticle spatial resolution on the time scale of atomic motion. A stringent enhancement of the UEM temporal resolution is demanded for recording snapshots of the electron motion which will provide a real-time access to all microscopic motions outside the atomic core and radically change our insight into the workings of the microcosm. Here, we…

Research Statement Past research accomplishments. Probing the dynamics of neuronal activities is crucial to understand the complex mechanisms of the brain and related diseases. Thus, there are great demands on optogenetic indicators for neuronal activities. However, engineering desired optogenetic indicators is a well-known challenge, probably due to the delicate sensing mechanisms, and the lack of effective high-throughput screen. To tackle this, I developed several novel molecular evolution…

Medical image analysis plays a vital role in medical diagnosis is a broad area of education and research attention. Medical imaging techniques become a nature look with different characteristics depend upon the selection of modalities with the requirements ( Li Luo 2007). For example, CT offer supreme information on denser tissue with smaller amount distortion whereas Magnetic Resonance Image (MRI) offer superior information on soft tissue with supplementary distortion (Yong Yang et.al. 2010) …

Typically it consists of two conductive plates with a dielectric material in between them. For parallel plate capacitors, capacitance can be expressed as, C = [ (Aεoεr)/d ]. Where Cis the capacitance, A is the overlapping area of the two plates, εois the permittivity of free space, εr is the relative permittivity of the dielectric material and d is distance between the plates. Capacitive sensors can be made very small, which allows the construction of dense sensor arrays. In general, capacitive…

information, surveillance and target acquisition. It was realized that destruction of the enemy's means of command and control should be the prime tenet of military doctrine. The Gulf War demonstrated several high-tech weapon systems, surveillance and target acquisition and command and control systems. Historically, man has always attempted to extend the range and lethality of his weapons. In the post-modern age, technology breakthroughs are being achieved with increasing frequency and…
