New chemotherapeutic compounds are needed to combat multidrug-resistant Mycobacterium tuberculosis (Mtb), which remains a serious public-health challenge. Decaprenylphosphoryl-β-D-ribose 2'-epimerase (DprE1 enzyme) has been characterized as an attractive therapeutic target to address this urgent demand. Herein, we have identified a new class of DprE1 inhibitors benzothiazinethiones as antituber...

We present results and first epoch parsec-scale images from a monitoring program on five γ–ray loud blazars selected on the basis of their total flux density variability. We observed 0048−097, 0235+164, 0954+658, 1510−089 and 1749+096 with the Very Long Baseline Array simultaneously at 8.4 GHz and 22 GHz. Comparison between our high quality images and previous results from the literature sugges...

In 1999, the highly compact and variable BL Lac object AO 0235+164 was identified as the highest brightness temperature active galactic nucleus observed with the VLBI Space Observatory Programme (VSOP), with TB > 5.8× 1013K (Frey et al. 2000). The sub-milliarcsec radio structure of this source has been studied with dualfrequency (1.6 and 5GHz), polarization-sensitive VSOP observations during 20...

We examine the power of constant depth circuits with sigmoid (i.e. smooth) threshold gates for computing boolean functions. It is shown that, for depth 2, constant size circuits of this type are strictly more powerful than constant size boolean threshold circuits (i.e. circuits with linear threshold gates). On the other hand it turns out that, for any constant depth d, polynomial size sigmoid t...

In this paper we briefly present the design of a distributed relational data base system. Then, we discuss experimental observations of the performance of that system executing both short and long commands. Conclusions are also drawn concerning metrics that distributed query processing heuristics should attempt to minimize. Lastly, we comment on architectures which appear viable for distributed...

We report the results of a non-LTE Fe, O and Mg abundance analysis of the carbon-nitrogen-rich ultrametal-poor giants CS 29498–043 and CS22949–037. The abundance of oxygen has been derived from measurements of the oxygen triplet at 7771–5 Å in high resolution spectra obtained with KeckI/HIRES and the forbidden line [O i] 6300 Å detected in the TNG/SARG spectra of CS 29498-043. Detailed non-LTE ...

Rootstock adequacy and planting density are necessary for new grapevine varieties in regions. The objective of this work was to select the rootstock that confers best productive performance ‘Vermentino’ variety, adjust ideal spacing combination. experimental design used randomized blocks a 5x3 factorial scheme, which treatments studied consisted combination five rootstocks (‘101-14 Mgt’, ‘Harmo...
