Information &Functional Materials, EarlyView.A new molecular cocrystal shows D‐A alternative molecular stacking, cyan‐blue photoluminescence with lifetime of 19.76 ns, and two‐photon absorption enabled emission under laser excitation between 720 and 880 nm. Theoretical calculations reveal its static dipole moment of 2.84 D, CT character in the ground, S1, and S2 excited states, and the TPA ...

Quantum mechanics of an electron in a homogeneous magnetic field and a singular magnetic flux tube
, 2000 The eigenvalue problem of the Hamiltonian of an electron confined to a plane and subjected to a perpendicular time-independent magnetic field which is the sum of a homogeneous field and an additional field contributed by a singular flux tube, i.e.

Irrigation and Drainage, EarlyView.ABSTRACT Flow rates for applying nutrient solutions in hydroponic systems are empirically known, yet uncertainties remain regarding whether brackish water affects the optimal flow rate and, consequently, biomass production and allocation. This study evaluated whether variations in application flow rate affect coriander biomass when brackish water is ...

Coupled three-form dark energy
, 2013 Cosmology with a three-form field interacting with cold dark matter is considered. In particular, the mass of the dark matter particles is assumed to depend upon the amplitude of the three-form field invariant.

Early Autonomic Burden in Prodromal Parkinson's Disease Predicts Cognitive Impairment
Movement Disorders, EarlyView.Abstract Background Autonomic dysfunction is a known contributor to cognitive impairment in Parkinson's disease (PD), but its impact during prodromal stage is unknown. Objective The aim was to determine whether early autonomic burden predicts incident cognitive impairment in prodromal PD.

Superexchange in the quarter- filled two- leg ladder system NaV2O5
, 2000 A theory of superexchange in the mixed valent layer compound NaV2O5 is presented which provides a consistent description of exchange both in the disordered and charge ordered state. Starting from results of band structure calculations for NaV2O5 first an
