Discovery and Biosynthesis of Celluxanthenes, Antibacterial Arylpolyene Alkaloids From Diverse Cellulose‐Degrading Anaerobic Bacteria

open access: yesAngewandte Chemie, EarlyView.
The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

Study of fluoroquinolones resistance in rifampicin‐resistant tuberculosis patients in Beijing: Characteristics, trends, and treatment outcomes

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We collected the clinical isolates from all patients with pulmonary TB in Beijing from January 2016 to December 2021, A total of 8,512 clinical isolates were collected, and 261 RR‐TB strains were screened. We conducted the drug sensitivity tests and sequencing for LFX and MFX. The MICs of the strains were mainly distributed at 0.25 μg/mL for both drugs,

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota

open access: yesAngewandte Chemie, EarlyView.
Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

SYNOPTIC CONDITIONS THAT TRIGGERED ABSOLUTE MINIMUM TEMPERATURES IN THE PRAHOVA CORRIDOR BETWEEN 1961-2007 [PDF]

open access: yesAerul şi Apa: Componente ale Mediului, 2013
In order to identify and describe the synoptic conditions which produced the waves of cold in the Prahova Corridor, the absolute minimum air temperatures in the cold semester of the year were analysed for the period 1961-2007 with homogenous data of the ...

[Review of] Jamake Highwater. The Sun, He Dies [PDF]

open access: yes, 1984
How do we ever own our history? How do we ever come to grips with our fairy tales of that history? How do we ever rationalize genocide? The Sun, He Dies makes us ask.

On the Optimality of Trees Generated by ID3 [PDF]

open access: yesarXiv, 2019
Since its inception in the 1980s, ID3 has become one of the most successful and widely used algorithms for learning decision trees. However, its theoretical properties remain poorly understood. In this work, we introduce a novel metric of a decision tree algorithm's performance, called mean iteration statistical consistency (MIC), which measures ...

Performance Analysis and Efficient Execution on Systems with multi-core CPUs, GPUs and MICs [PDF]

open access: yesarXiv, 2015
We carry out a comparative performance study of multi-core CPUs, GPUs and Intel Xeon Phi (Many Integrated Core - MIC) with a microscopy image analysis application. We experimentally evaluate the performance of computing devices on core operations of the application. We correlate the observed performance with the characteristics of computing devices and
