High dynamic range imaging

dose – no matter whether the patient has an unstable heart condition, cannot hold his breath, or is obese, very tall, poly-traumatized, or a moving child. Its unmatched innovations include a 78 cm gantry bore, 307 kg capacity, 2 x 100 kW, 2 m scan range, whole-organ perfusion coverage, and 75 ms temporal resolution. Pediatric chest & body CT. Without sedation. The SOMATOM Definition Flash scan speed resulted in a scan time of a fraction of a second for the whole chest and body, and we could…

Transmission electron microscopy, or TEM, is a variation of low field, high-powered electron microscopy. Created by Ernest Ruska and Max Knoll of the Berlin Technische Hochschule in 1931, the invention of this novel microscope allowed for the surpassing of the visible light resolution barrier. Since its inception, the TEM has become a resolution standard in the field of imagery, and further advances have led to the progression of high quality atomic viewing. The development of the electron…

As macromolecular machines, enzymes conduct their designated work in the confined and crowded spaces inside living cells. How does a protein work in such a condition? Functions of proteins are strongly dependent on their structural stability and dynamics while the (macro) molecular interactions are arguably affected by the complexity and diversity of their environments. To date, two interrelated cellular conditions — ‘macromolecular crowding’ resulted from the effect of volume exclusion by…

has Young’s modulus of about 1 TPa [Ref], shear modulus of 280 GPa [Ref], fracture strength of 130 GPa [Ref], thermal conductivity of 5000 W/mK [Ref], longitudinal sound velocity of 20Km/s [Ref], melting temperature of 4900 K [Ref] and also it has high electron mobility of 250,000 cm2/Vs [Ref] at room temperature. All these exceptional properties can be attributed due its 2D (two dimensional) honeycomb lattice of sp2-hybridized carbon atoms as shown in [Fig 1]. Due to the above said properties…

hyperpolarization occurs. The data in figures one through four support these claims. I agree with the author’s claims that ASAP 1 is a viable choice for experimentation of this nature because Figures one through four support the speed of data capture, dynamic range of reporting, large florescent volume, and real time results that give a clear indication of voltage…

Second, we further studied the continuous rotation dynamics of NP-dimers with increasing asymmetries, and observed a full transition picture from the conventional diffusive to superdiffusive rotation, and further to ballistic rotation. Because a better statistic is needed for revealing this transition picture, we performed the following experiments in the continuous e-beam imaging mode where each experiment could contain hundreds to thousands of data points. Presented in Fig. 4A are the typical…

The Machines - Why TransEnterix And Titan Medical Are Strong Buys? Nov. 2, 2015 10:15 AM ET | Includes: GOOG, ISRG, MZOR, TITXF, TRXC, YAMCF Disclosure: I am/we are long TRXC, TITXF. (More...) Summary Robotic industry compound annual growth rates range from 8% to 25% in personal, industrial, commercial, military and surgical market segments. Surgical robotics is the most attractive market segment to invest in our opinion. We discuss why. We discuss four stocks in the robotic surgery:…

50% limited in all motions, left lower extremity passive range of motion had spasticity at an Ashworth scale grading of 1+ meaning there was slight increase in tone followed by a catch that was continued throughout the rest of the range.10 Bohannon and Smith10 determined that the Modified Ashworth Scale is of approximately 87% agreeance between two clinicians, however it is reported more studies should be utilized. Lower extremity active range of motion was limited due to weakness and spasticity…

An inverted fluorescence microscope is an inverted compound light microscope equipped with modules to internally separate the different wavelengths of light, and direct them to respective detection channels. Its main components include a light source, an objective, a filter cube and a detection unit, which can be an eyepiece or a camera (Fig.1). Filter cube is a component which separates a fluorescence microscope from a light microscope. It consists of one excitation filter, one emission filter…

creating referable understanding models of any size, density, or complexity. This ability significantly increases the adaptive capacity of people and animals. Unlike the separate cognitive functions, advanced intelligence is the ability to solve a wide range of different tasks, including tasks which the subject faces for the first time in life. Education, cultural and social environment…
