Size-dependent Energy gap in Some Semiconductor Nanomaterials [PDF]

Kirkuk Journal of Science
This research discusses how the variation in band gap with the change of particle size nano level for CdS, GaAs, InN, and InP has been measured theoretically from a model based on energy differences between nanoparticles and their corresponding bulks ...

Canopy gaps in two virgin beech forest reserves in Slovakia

Journal of Forest Science, 2005
The formation, size distribution and percentage of gaps in two virgin deciduous forests are presented in two case studies. Gaps are defined as openings in the canopy above 2/3 of stand height.

Effects of gap size and within-gap position on seedlings establishment in silver fir stands

iForest - Biogeosciences and Forestry, 2008
The conversion of pure conifer plantations into stands with heterogeneous structure and composition is a current silvicultural challenge in Italy. A silvicultural system aiming to the regeneration of natural forests by means of openings in the canopy ...

Gap-Size-Dependent Effective Phase Transition in Metasurfaces of Closed-Ring Resonators

Crystals, 2021
We theoretically investigate a metal-to-insulator transition in artificial two-dimensional (2D) crystals (i.e., metasurfaces) of tightly coupled closed-ring resonators.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Impacts of the gap size between two bluff bodies on the flow field within the gap [PDF]

, 2017
When two bluff bodies is in close tandem, i.e, the distance between blocks D is less than half of the height of the body H, the flow field is very similar to that in the gap between tractor and trailer in a truck, and hence understanding such a flow ...

Size-Dependent Band-Gap and Molar Absorption Coefficients of Colloidal CuInS2 Quantum Dots

, 2018
The knowledge of the quantum dot (QD) concentration in a colloidal suspension and the quantitative understanding of the size-dependence of the band gap of QDs are of crucial importance from both applied and fundamental viewpoints.

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Beam-Size-Invariant Spectropolarimeters Using Gap-Plasmon Metasurfaces [PDF]

, 2017
Metasurfaces enable exceptional control over the light with surface-confined planar components, offering the fascinating possibility of very dense integration and miniaturization in photonics.

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
