Kinematic characteristics of elite men's 50 km race walking. [PDF]
, 2013 Race walking is an endurance event which also requires great technical ability, particularly with respect to its two distinguishing rules. The 50 km race walk is the longest event in the athletics programme at the Olympic Games.

Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions
Advanced Materials, EarlyView.This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

The communicative advantage: how kinematic signaling supports semantic comprehension
Psychological Research, 2019 Humans are unique in their ability to communicate information through representational gestures which visually simulate an action (eg. moving hands as if opening a jar).

Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity
Advanced Materials Interfaces, EarlyView.Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation
Advanced Materials Technologies, EarlyView.Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

RESEARCH ON THE KINEMATICS OF A MECHANISM WITH A TRIAD AS A COMPONENT
Romanian Journal of Petroleum & Gas TechnologyThe structural approach to mechanisms from the perspective of component kinematic groups shows that as the class of component groups increases, the complexity of the mechanisms that contain them also increases. From this perspective, it is obvious that solving problems related to the kinematics of these mechanisms also becomes much more difficult to ...

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control
Advanced Materials Technologies, EarlyView.A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Kinematic research of spatial four]link not Assurian mechanism
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 Relevance of the research is caused by the need to explore new mechanisms that differ in structure from the Assyrians ones, for their subsequent usage in engineering practice. The main aim of the study is to study and development the universal method for
