Filling Factor Dependence of the Fractional Quantum Hall Effect Gap [PDF]

Physical Review Letters, 2008
We directly measure the chemical potential jump in the low-temperature limit when the filling factor traverses the nu = 1/3 and nu = 2/5 fractional gaps in two-dimensional (2D) electron system in GaAs/AlGaAs single heterojunctions. In high magnetic fields B, both gaps are linear functions of B with slopes proportional to the inverse fraction ...

Restoration of above canopy reference hemispherical image from below canopy measurements for plant area index estimation in forests/ Metsa võrastiku läbipaistvuse mõõtmine digitaalsete poolsfäärikaamerate abil

Metsanduslikud Uurimused, 2013
Canopy gap fraction has been estimated from hemispherical images using a thresholding method to separate sky and canopy pixels. The optimal objective thresholding rule has been searched by many authors without satisfactory results due to long list of ...

Olive Crown Porosity Measurement Based on Radiation Transmittance: An Assessment of Pruning Effect

Sensors, 2016
Crown porosity influences radiation interception, air movement through the fruit orchard, spray penetration, and harvesting operation in fruit crops. The aim of the present study was to develop an accurate and reliable methodology based on transmitted ...

Evidence for Independent Heritability of the Glycation Gap (Glycosylation Gap) Fraction of HbA1c in Nondiabetic Twins [PDF]

Diabetes Care, 2006
OBJECTIVE—HbA1c (A1C) is substantially determined by genetic factors not shared in common with glucose. Fractions of the variance in A1C, the glycation gap (GG; previously called the glycosylation gap) and the hemoglobin glycosylation index, correlate with diabetes complications.

Extracting Leaf Area Index by Sunlit Foliage Component from Downward-Looking Digital Photography under Clear-Sky Conditions

Remote Sensing, 2015
The development of near-surface remote sensing requires the accurate extraction of leaf area index (LAI) from networked digital cameras under all illumination conditions.

Hard color-singlet exchange in dijet events in proton-proton collisions at $\sqrt{s} = 13$ TeV

SciPost Physics Proceedings, 2022
We present a measurement of events with two jets separated by a pseudorapidity gap (jet-gap-jet). The signature is expected from hard color-singlet exchange. The jets are reconstructed with the CMS detector. The highest $p_\text{T}$ jets have $p_\text{T}^

Radiobiological rationale for compensation for gaps in radiotherapy regimes by post-gap acceleration of fractionation

The British Journal of Radiology, 1990
Abstract It is now recognized that clonogenic tumour cells may repopulate vigorously during radiotherapy. Gaps in treatment schedules which lead to prolongation of overall treatment time may therefore cause sparing of tumour. Acute-responding normal tissues will also be spared if repopulation by surviving stem cells takes place. However,

Topological phases in gapped edges of fractionalized systems [PDF]

Physical Review B, 2013
Recently, it has been proposed that exotic one-dimensional phases can be realized by gapping out the edge states of a fractional topological insulator. The low-energy edge degrees of freedom are described by a chain of coupled parafermions. We introduce a classification scheme for the phases that can occur in parafermionic chains.

Effects of topography, soil type and forest age on the frequency and size distribution of canopy gap disturbances in a tropical forest [PDF]

Biogeosciences, 2013
Treefall gaps are the major source of disturbance in most tropical forests. The frequency and size of these gaps have important implications for forest ecosystem processes as they can influence the functional trait distribution of tree communities, stand-
