Elastic Coiling-up-Space Metamaterial
, 2021 Coiling up space is a metamaterial technique that utilizes a subwavelength labyrinthine structure to achieve a high refractive index. Despite the various advances in acoustics, the coiling-up-space technique cannot be used in the elastic case owing to ...

UMBILICAL COILING INDEX AND ITS RELATIONSHIP WITH PERINATAL OUTCOMES
International Journal of Advanced Research, 2022 Aim: To evaluate any adverse perinatal outcomes associated with abnormal coiling of umbilical cord. Introduction:The primary objective of antenatal and intrapartum fetal surveillance both in early and late pregnancy is to prevent fetal death. One of the most important parts of the fetoplacental unit is the umbilical cord.

Umbilical Coiling Index and Perinatal Outcome
MVP Journal of Medical Sciences, 2016 Objective(s): To study the association of umbilical coiling index and perinatal outcome. Method(s): One hundred and eighty five umbilical cords were examined. A coil is defined as a complete 360 degree spiral course of umbilical vessels around the Wharton's jelly.

Umbilical Coiling Index, A Predictor of Perinatal Outcome
International Journal of Research in Pharmaceutical Sciences, 2020 Umbilical cord (UC) represents the “life source”, or the “entry and exit” point of humans which is the only source of energy. It is essential for the development, well-being, and survival of the nourishing baby. The characteristic of the coiling of the umbilical cord makes the cord a structure that is both flexible and strong and provides resistance to

Umbilical cord coiling index as a marker of perinatal outcome
Indian Journal of Obstetrics and Gynecology Research, 2021 The umbilical cord is very important for the well-being and survival of the fetus, however this is susceptible to compressions, kinking, traction and torsion which may influence the perinatal outcome and an abnormal umbilical coiling index has been related to adverse fetal and pregnancy outcomes.

Measurement of a Broadband Negative Index with Space-Coiling Acoustic Metamaterials
Physical Review Letters, 2013 We report the experimental demonstration of broadband negative refractive index obtained in a labyrinthine acoustic metamaterial structure. Two different approaches were employed to prove the metamaterial negative index nature: one-dimensional extractions of effective parameters from reflection and transmission measurements, and two-dimensional prism ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
