Multidimensional Image Processing & Analysis in R/ripa/magick in the Context of Cryo-Em/tem/sem Images – an Insight Into 'R' Based Electron Microscopy(em) Image Processing Based on Mva.

Authors: Nirmal Tej Kumar
Comments: 3 Pages. Simple Technical Note on cryo-EM Image Processing using R Language

Researchers believe that an open-source programming language for statistical analysis “called R”,could certainly pave the way for solving demanding scientific applications like Cryo-EM image processing.As we see today, thousands of international scientists are participating in the R development community programs contributing towards the development of new tools and libraries.It is in this context,that the author intends to reap the benefits of R/RIPA/Magick Tools & Multivariate Analysis concept(MVA) to process Cryo-EM/TEM/SEM images.

Phase-Change Memory Devices

A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25] A research team from Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation. [24] Topological effects, such as those found in crystals whose surfaces conduct electricity while their bulk does not, have been an exciting topic of physics research in recent years and were the subject of the 2016 Nobel Prize in physics. [23] A new technique developed by MIT researchers reveals the inner details of photonic crystals, synthetic materials whose exotic optical properties are the subject of widespread research. [22] In experiments at SLAC, intense laser light (red) shining through a magnesium oxide crystal excited the outermost " valence " electrons of oxygen atoms deep inside it. [21] LCLS works like an extraordinary strobe light: Its ultrabright X-rays take snapshots of materials with atomic resolution and capture motions as fast as a few femtoseconds, or millionths of a billionth of a second. For comparison, one femtosecond is to a second what seven minutes is to the age of the universe. [20] A 'nonlinear' effect that seemingly turns materials transparent is seen for the first time in X-rays at SLAC's LCLS. [19] Leiden physicists have manipulated light with large artificial atoms, so-called quantum dots. Before, this has only been accomplished with actual atoms. It is an important step toward light-based quantum technology. [18]

Higher Order Logic (HOL) Based Analysis of Cryo-EM Images Using Multivariate Analysis,Automatic Data Refinement Libraries Involving Vector Spaces for the HOL-Scala-ImageJ-JikesRVM(JVM) Environment to Probe Nano-Bio Systems – A Technical Note.

Authors: Nirmal Tej Kumar
Comments: 5 Pages. Technical Note on cryo-EM Image Processing using HOL-SCALA/IMAGEJ/JIKESRVM

Cryo-Electron Microscopy(cryo-EM/Cryo-EM) : is a promising method for the imaging of macromolecules in the electron microscope, especially “single-particle” techniques are powerful and popular.As the title of this technical notes indicates it was proposed to probe the frontiers of “Nano-Bio” Systems by using HOL Platform and its associated mathematical concepts,algorithms and libraries to process Cryo-EM Images.

Cloud Quantum Computing

Authors: George Rajna
Comments: 54 Pages.

A team of researchers at Oak Ridge National Laboratory has demonstrated that it is possible to use cloud-based quantum computers to conduct quantum simulations and calculations. [34] Physicists have designed a new method for transmitting big quantum data across long distances that requires far fewer resources than previous methods, bringing the implementation of long-distance big quantum data transmission closer to reality. [33] A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). [32] In the race to build a computer that mimics the massive computational power of the human brain, researchers are increasingly turning to memristors, which can vary their electrical resistance based on the memory of past activity. [31] Engineers worldwide have been developing alternative ways to provide greater memory storage capacity on even smaller computer chips. Previous research into two-dimensional atomic sheets for memory storage has failed to uncover their potential—until now. [30] Scientists used spiraling X-rays at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) to observe, for the first time, a property that gives handedness to swirling electric patterns – dubbed polar vortices – in a synthetically layered material. [28] To build tomorrow's quantum computers, some researchers are turning to dark excitons, which are bound pairs of an electron and the absence of an electron called a hole. [27] Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics (MPQ) have now achieved a major breakthrough: they demonstrated the long-lived storage of a photonic qubit on a single atom trapped in an optical resonator.

[26] Achieving strong light-matter interaction at the quantum level has always been a central task in quantum physics since the emergence of quantum information and quantum control. [25]
