Abstract The global photonics market has grown very rapidly in recent years and reached 733 billion US dollars 2019. European industry also had a sharp increase (from € 76 B 2015 to 103 2019), outperforming EU GDP by three times. Moreover, the proven be quite resilient effects of Covid‐19 crisis. In fact, already present various high‐end next‐generation products, technology long‐term driver gro...
To better understand the decay of vertically polarised fast kink modes of coronal loops by the mechanism of wave tunneling, simulations are performed of fast kink modes in straight flux slabs which have Alfvén speed profiles which include a tunneling region. The decay rates are found to be determined by the mode number of the trapped mode and the thickness of the tunneling region. Two analytica...
BACKGROUND/AIMS Chicken skin mucosa (CSM), surrounding colorectal adenoma, is an endoscopic finding with pale yellow-speckled mucosa; however, its clinical significance is unknown. This study aimed to evaluate the prevalence and clinical characteristics of CSM, and the association between colorectal carcinogenesis and CSM. METHODS This cross-sectional study was performed in 733 consecutive pa...
Evidence for two spectroscopically different dimers of light-harvesting complex I from green plants.
A preparation consisting of isolated dimeric peripheral antenna complexes from green plant photosystem I (light-harvesting complex I or LHCI) has been characterized by means of (polarized) steady-state absorption and fluorescence spectroscopy at low temperatures. We show that this preparation can be described reasonably well by a mixture of two types of dimers. In the first dimer about 10% of a...
Background: To study the reliability of a single Widal test and to find out the diagnostic significance of ‘O’ and ‘H’ agglutinin titre in the diagnosis of typhoid fever. Methods: Community-based case-control study conducted from Jan 2001 to June 2007. The blood samples were collected from the medical and out door department of Sir Ganga Ram Hospitals, Lahore. The diagnostic value of an acute p...
