A second, natural alternative approach to QKD protocols is to use continuous-variable (CV) systems [83-95]. In general, thanks to the use of an infinite-dimensional Hilbert space, CV systems can transfer more information per signal compared with qubit-based approaches and rely on cheaper technological implementations; this advantage can be ...

Astronomical Times. There are two widely used time standards. One is the rotation of the earth, and the other is the frequency of atomic oscillations (mainly the cesium-133 atom). The earth's rotation is not uniform. Its rate exhibits both periodic changes and long term drifts on the order of a second per year.

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for November, 2021 was +0.08 deg. C, down substantially from the October, 2021 value of +0.37 deg. C. The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).
Type of ball mills, centrifugal and planetary mills, are devices used to rapidly grind materials to colloidal fineness (approximately 1 μm and below) by developing high grinding energy via centrifugal and/or planetary action.

activation was carried out in planetary mill AGO-2 (acceleration of 40 g) with steel vials and steel balls of 8 mm in diameter [6] as well as in flow centrifugal mill of continuous action [2, 3, 13]. In the case of AGO-2, ball mass to sample mass ratio was 20:1, the activation time was varied from 5 to 15 minutes.
Courtesy: Letstute As per physics and mechanics, there are mainly 4 types of motion, i.e. Rotary Motion: A special type of motion in which the object is on rotation around a fixed axis like, a figure skater rotating on an ice rink.; Oscillatory Motion: A repeating motion in which an object continuously repeats in the same motion again and again like a swing.

Twenty-five years ago, the underlying genetic cause for one of the most common and devastating inherited diseases in humans, spinal muscular atrophy (SMA), was identified. Homozygous deletions or, rarely, subtle mutations of SMN1 cause SMA, and the copy number of the nearly identical copy gene SMN2 inversely correlates with disease severity. SMA has become a …

Continuous deodorizers are the best option for high-capacity plants running on a single feedstock (which is how most refining plants operate nowadays). The main advantages are the moderate investment costs, potentially high heat recovery and easy maintenance. An overview of the various configurations can be found in the literature [5,6].

12%Laboratory planetary mills have been widely used by researchers studying effects of mechanochemical activation. These mills are usually of the batch type (they need periodic loading-unloading). Scaling up of the planetary mills was considered to be intrinsically impossible. In the recent years successful technical solutions for the problem of continuous …

In a Logix5000 controller, the continuous task operates as a background task at the lowest priority. It uses any CPU time that remains after the controller executes the other tasks. Like the continuous task, a periodic task executes all of its code from top to bottom. However, when a periodic task completes its scan, it waits a pre-

You can use the value and description keywords to define pipeline-level (global) variables that are prefilled when running a pipeline manually.. In pipelines triggered manually, the Run pipelines page displays all top-level variables with a description and value defined in the .gitlab-ci.yml file. The values can then be modified if needed, which overrides the value for that single pipeline run.
