In 1954, Cohen and Barner discovered that a thymine auxotrophic (thyA) mutant of Escherichia coli undergoes cell death in response to thymine starvation. This phenomenon, called thymineless death (TLD), has also been found in many other organisms, including prokaryotes and eukaryotes. Though TLD has been studied intensively, its molecular mechanism has not yet been explained. Previously we repo...

During early Drosophila embryogenesis, several zygotic gene products act to establish a posttranscriptional activity gradient of the morphogen DPP. Among these molecules, Tolloid, a putative metalloprotease related to BMP-1, enhances DPP function, while SOG, an ortholog of the Xenopus organizer Chordin, inhibits DPP function. Using epistasis tests and a Xenopus secondary axis induction assay, w...

The lack of privacy in DNS and DNSSEC is a problem that has only recently begun to see widespread attention by the Internet and research communities, and the solutions proposed so far only look at a narrow slice of the design space. In this paper we investigate a new approach for a privacy-preserving DNS mechanism that hides query information from root name servers and TLD registries. Our archi...

This work presents a system for detection and tracking humans (Parkinson disease patients in our special case) in their natural home environment observed by a static single color surveillance camera. The purposed method emloys modified TLD tracker. The modifications enable the TLD to track multiple objects of multiple different classes at a time. The TLD can newly benefit from an external objec...

In this work we report a study on the structure, optical and electrical properties of P, Sb and Al implanted ZnO thin films that had been produced by r.f. magnetron sputtering. The influence of the different replacing atoms on the structure and properties of the films has been explored. Looking for the best annealing conditions, two different annealing temperatures (300 degrees C and 500 degree...

Desde su creación en 1978 la Escuela de Adultos La Verneda-Sant Martí, situada uno los barrios más desfavorecidos y marginados Barcelona época, las Tertulias Literarias Dialógicas (TLD) han generado transformaciones sociales contextos diversos, diferentes países, con personas diferente nivel socioeconómico educativo distintas edades. entonces desafiado teorías racistas clasistas corrientes pens...

OBJECTIVE To examine the effectiveness and feasibility of an evidence-based treatment for weight loss in children. METHODS A total of 41 children who were overweight and their families were provided a modified version of the Traffic Light Diet (TLD) in an applied setting. Children who received treatment as usual (TAU) constituted a comparison sample. RESULTS Children receiving the modified ...

Efficient and equitable dispute resolution is key to avoiding systemic disturbance in the use and valorization of top level domain names (TLDs). Such dispute resolution is also important given the increasing number of clashes between TLD providers and managers and between trademark owners and generic (gTLD)-related registrants. ICANN policies/rules form the basis of gTLD-related second level do...

The application of ionizing radiations in different fields requires the use of equipment capable of detecting their presence or quantifying them. Detectors of the most different shapes, composition and characteristics are required to cover the full range of application of ionizing radiations. At present, thermoluminescent detectors (TLD) are the most widely employed for individual gamma monitor...
