Article Synopsis
- * It identifies that surface pits, ranging in size and depth, are influenced by factors such as substrate annealing temperature and the alloy composition of InAlAs.
- * A model is proposed linking the formation of these surface pits and composition clusters to local strain fields near threading dislocations affecting the incorporation of In adatoms during growth.

Article Synopsis
- Crouzon syndrome, which affects 1 in 25,000-31,000 newborns, is rarely linked with optic canal stenosis, a condition that can affect vision.
- A 6-year-old boy with Crouzon syndrome underwent multiple surgeries but experienced worsening vision, leading to the discovery of optic canal stenosis via MRI and confirmed by 3D CT.
- After surgical decompression of the optic canals, the patient's vision improved, suggesting that addressing optic canal stenosis can be beneficial even after prolonged symptoms.
The strategy for the synthesis of substituted [(3-nitro-1-1,2,4-triazol-1-yl)--azoxy]furazans 4-7, in which the distal nitrogen of the azoxy group is bonded to the nitrogen atom of the azole ring, includes, firstly, the reaction of 1-amino-3-nitro-1-1,2,4-triazole with 2,2,2-trifluoro--(4-nitrosofurazan-3-yl)acetamide in the presence of dibromisocyanuric acid followed by removing of the trifluoroacetyl protecting group to afford aminofurazan (4). Transformation of the amino group in the latter made it possible to synthesize the corresponding nitro (5), azo (6), and methylene dinitramine (7) substituted furazans. The compounds synthesized are thermally stable (decomposition onset temperatures 147-228 °C), exhibit acceptable densities (1.

Objective: Morphological study of Tc and Pc roles in GBM.
