Optimized Hybrid Deep Learning Framework for Early Detection of Alzheimer's Disease Using Adaptive Weight Selection.

Background: Alzheimer's disease (AD) is a progressive neurological disorder that significantly affects middle-aged and elderly adults, leading to cognitive deterioration and hindering daily activities. Notwithstanding progress, conventional diagnostic techniques continue to be susceptible to inaccuracies and inefficiencies. Timely and precise diagnosis is essential for early intervention.

Bis(2-meth-oxy-anilinium) hexa-bromido-stannate(IV) dihydrate.

The asymmetric unit of the title compound, (C7H10NO)2[SnBr6]·2H2O, contains one cation, one half-dianion and one lattice water mol-ecule. The [SnBr6](2-) dianion, located on an inversion center, exhibits a highly distorted octa-hedral coordination environment, with Sn-Br bond lengths ranging from 2.2426 (9) to 3.

Bis(3-aza-niumylprop-yl)aza-nium hexa-chlorido-bis-muthate(III) monohydrate.

The asymmetric unit of the title compound, (C6H20N3)[BiCl6]·H2O, consists of a triprotonated bis-(3-aza-niumylprop-yl)aza-nium cation, two halves of an octahedral [BiCl6](3-) anion, each of the Bi(III) atoms lying on an inversion centre, and a water mol-ecule. In the crystal, the anions and water mol-ecules are linked by O-H⋯Cl hydrogen bonds, forming chains running parallel to [0-11]. The anionic chains and the cations are further linked into a three-dimensional network by N-H⋯Cl and N-H⋯O hydrogen-bond inter-actions.

Tris(N,N-di-methyl-anilinium) hexa-bromido-stannate(IV) bromide.

In the title compound, (C8H12N)3[SnBr6]Br, the anilinium N atom of one of the three unique cations exhibits flip-flop disorder with an 0.60:0.40 occupancy ratio.
