Multi-Source Transfer Learning via Ensemble Approach for Initial Diagnosis of Alzheimer's Disease.

Alzheimer's disease (AD) is one of the most common progressive neurodegenerative diseases, and the number of AD patients has increased year after year with the global aging trend. The onset of AD has a long preclinical stage. If doctors can make an initial diagnosis in the mild cognitive impairment (MCI) stage, it is possible to identify and screen those at a high-risk of developing full-blown AD, and thus the number of new AD patients can be reduced.

Development of Femoral Head Interior Supporting Device and 3D Finite Element Analysis of its Application in the Treatment of Femoral Head Avascular Necrosis.

Background: The aim of this study was to develop and perform the 3D finite element analysis of a femoral head interior supporting device (FHISD).

Material And Methods: The 3D finite element model was developed to analyze the surface load of femoral head and analyze the stress and strain of the femoral neck, using the normal femoral neck, decompressed bone graft, and FHISD-implanted bone graft models.

Results: The stress in the normal model concentrated around the femoral calcar, with displacement of 0.

A family of three-dimensional 3d-4f and 4d-4f heterometallic coordination polymers based on mixed isonicotinate and 2-sulfobenzoate ligands: syntheses, structures and photoluminescent properties.

Hydrothermal reactions of isonicotinic acid (Hina), 2-sulfobenzoic acid (H(2)sba), d-block metal salts and lanthanide oxides/hydroxides yielded 17 three-dimensional (3D) 3d-4f and 4d-4f heterometallic coordination polymers (HCPs). They are formulated as [LaAg(sba)(ina)(2)](n) (1), [Ln(2)Ag(2)(sba)(2)(ina)(4)(H(2)O)(2)](n) [Ln = Pr (2), Nd (3), Sm (4), Eu (5), Gd (6), Tb (7), Dy (8), Ho (9), Er (10)] and [Ln(2)Cu(2)(sba)(2)(ina)(4)(H(2)O)(2)](n) [Ln = La (11), Pr (12), Nd (13), Sm (14), Eu (15), Gd (16), Tb (17)]. Their structures were characterized by single crystal X-ray diffraction, powder X-ray diffraction (XRD), infrared (IR) spectroscopy, elemental analysis (EA), and thermogravimetric analysis (TGA).

Bis(4H-1,2,4-triazol-3-yl)disulfane.

The title compound, C(4)H(4)N(6)S(2), was synthesized by the reaction of 3-mercapto-1H-1,2,4-triazole with sodium hydrox-ide in ethanol. The mol-ecule possesses a crystallographically imposed twofold axis. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains along the c axis.
