Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet

Advanced Materials, EarlyView.
Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Body Height Changes from Vibration

Spine, 1987
A device for measuring body height is reported (SD, 1 mm). The change in body height before and after vibration and quiet sitting respectively was studied in eight men aged 22-44 years who were free of back pain. The vibration frequency was set at 5 Hz and the acceleration at 2 msec-2.

Body height in Turner's syndrome

Clinical Genetics, 1982
Disease‐specific growth curves for Turner's syndrome were calculated by means of 2nd order homogeneous differential equations with constant coefficients, taking different cytogenetical subtypes into account. Comparison of these growth curves between X‐monosomic (n=64) and 46,XX/45,X‐mixoploid (n = 20) patients reveals no differences, in contrast to the

Body Height Measurements in Images

Journal of Forensic Sciences, 2009
Abstract:  For any measurement of a person’s height in an image, a difference exists between the actual height of the person and the image measurement. In order to gain knowledge about statistical behavior of differences between actual and measured heights it is necessary to make reference recordings, e.g., of test persons under the same recording ...

The association of body height, height variability and inequality

Anthropologischer Anzeiger, 2016
Body height is associated with environmental conditions. It has been suggested that under poor conditions when inequality within a population increases, also the variability in height tends to increase. We studied the association of body height, within-country variability in height and geographic and historic origin in 767 growth studies carried out in

Body height changes with hyperextension

Clinical Biomechanics, 1996
OBJECTIVE: To automatize the lumbar physical examination with an acceptable rate of error. DESIGN: An external skin marker method for automatizing the physical examination was developed and its ability to discriminate between normal and abnormal subjects tested in a blind clinical trial.

Body weight/height relationship: Exponential solution

American Journal of Human Biology, 1989
AbstractRegression of weight (W) on height (H) in all higher primates is of exponential form W = a · exp(H · b) and is uniform for both nongrowing adults and growing children. Parameter a values are always close to 2.0 and b to 0.02. The exponential equation fits ontogenetic data better than the traditional allometric power curve.
