Burden of rotavirus and adenovirus gastroenteritis in children and adults hospitalized in two geo-climatically different provinces of Sri Lanka.

Acute gastroenteritis is common in infants and children of Sri Lanka. There is limited information on the burden of rotavirus gastroenteritis in infants and children in Sri Lanka but none in adults. Adenovirus gastroenteritis is not previously reported in Sri Lanka.

On the principle of reciprocity in inelastic electron scattering.

In electron microscopy the principle of reciprocity is often used to imply time reversal symmetry. While this is true for elastic scattering, its applicability to inelastic scattering is less well established. From the second law of thermodynamics, the entropy for a thermally isolated system must be constant for any reversible process.

Impact of Socio-Demographics and Knowledge, Attitudes, and Practices (KAP) on Misconceptions of Metformin Use in Diabetes: A Potential Myth and Disbelief in South Asia.

Background: The influence of misconceptions and related socio-demographics on metformin use could hamper adherence to medications. This study aimed to assess the rates and causes of metformin non-adherence and to investigate knowledge, attitudes, and practices (KAP) on misconceptions of metformin use including the association with socio-demographic variables.

Methods: An observational analytical cross-sectional study was conducted at the diabetes clinic of Karapitiya Teaching Hospital in Galle, Sri Lanka.

Modelling dynamical 3D electron diffraction intensities. II. The role of inelastic scattering.

The strong interaction of high-energy electrons with a crystal results in both dynamical elastic scattering and inelastic events, particularly phonon and plasmon excitation, which have relatively large cross sections. For accurate crystal structure refinement it is therefore important to uncover the impact of inelastic scattering on the Bragg beam intensities. Here a combined Bloch wave-Monte Carlo method is used to simulate phonon and plasmon scattering in crystals.

Modelling dynamical 3D electron diffraction intensities. I. A scattering cluster algorithm.

Three-dimensional electron diffraction (3D-ED) is a powerful technique for crystallographic characterization of nanometre-sized crystals that are too small for X-ray diffraction. For accurate crystal structure refinement, however, it is important that the Bragg diffracted intensities are treated dynamically. Bloch wave simulations are often used in 3D-ED, but can be computationally expensive for large unit cell crystals due to the large number of diffracted beams.
