Position-dependent patterning of hair and non-hair cells in the Arabidopsis thaliana root epidermis is a powerful system to study the molecular basis of cell fate specification. Here, we report an epidermal patterning mutant affecting the ADENOSINE DIMETHYL TRANSFERASE 1A (DIM1A) rRNA dimethylase gene, predicted to participate in rRNA posttranscriptional processing and base modification. Consis...

We have isolated a single-copy gene from the plant Arabidopsis thaliana, called dbp, which encodes a lysine-rich, DNA-binding protein. The Dbp protein has a molecular weight and a composition resembling histone H1. When the dbp gene was expressed in bacteria, the protein product bound DNA nonspecifically. The dbp gene is expressed constitutively in all parts of the plant but is induced five tim...

over Bengal and the North-Western Provinces. In the latter place it is somewhat scarce in the hot weather, as it dries up by exposure to the powerful rays of the sun, but even then it can be found out there in shady places. In Bengal it is constantly found every where. Cows and rabbits are very fond of the leaves. In milking cows some people believe that it increases the secretion of milk. In t...

The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...

Due to their nature, Peer-to-Peer (P2P) systems are subject to a wide range of security issues. In this paper, we focus on a specific security property, called the root authenticity (or RA) property of the so-called structured P2P overlays. We propose a P2P architecture that uses Trusted Computing as the security mechanism. We formalize that system using a process algebra (CSP), then verify tha...

Complex diseases are caused by a multitude of factors that may differ between patients even within the same diagnostic category. A few underlying root causes nevertheless initiate development disease each patient. We therefore focus on identifying patient-specific disease, which we equate to sample-specific predictivity exogenous error terms in structural equation model. generalize from linear ...
