Effects of Cluster Particle Correlations on Local Parity Violation Observables [PDF]

, 2010
We investigate effects of cluster particle correlations on two- and three-particle azimuth correlator observables sensitive to local strong parity violation. We use two-particle angular correlation measurements as input and estimate the magnitudes of the

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Borehole Azimuth Correction Method Considering the Effect of Underground Magnetic Veins

Shiyou huagong gaodeng xuexiao xuebao
In order to improve the accuracy of magnetic azimuth measurement,it is often necessary to establish a more accurate local geomagnetic model to obtain precise magnetic declination information.Compared with global geomagnetic model, local geomagnetic model

Sun tracking solar energy collector [PDF]

, 1978
A parabolic reflector is supported so that it can track the sun. The support for this reflector comprises an azimuth frame supported on two wheels and a central pivotal point which are positioned in a substantially triangular configuration. On top of the

Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges

Advanced Functional Materials, EarlyView.
Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).

Archaeoastronomical object on Tuzluk Mount in the Elbrus region (Northern Caucasus) [PDF]

Archaeoastronomy and Ancient Technologies, 2019
The article presents the results of a study of an object of four megaliths (outcrops) of fairly regular forms on the top of Mount Tuzluk. Outcrops are separated by mutually intersecting passages, forming a shape similar to a cruciform with orientation to

Measurement technique for the determination of antenna directivity [PDF]

, 1969
Measurement of great circle patterns requires rotation in azimuth with discrete rotation in elevation. This technique eliminates a set of slip-rings and rotary joints and permits the use of larger models since only continuous azimuth rotation is ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

Advanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.
