The banded portion of Drosophila melanogaster chromosome 4 exhibits euchromatic and heterochromatic characteristics. Reminiscent of heterochromatin, it contains a high percentage of repetitive elements, does not undergo recombination, and exhibits high levels of HP1 and histone-3 lysine-9 dimethylation. However, in the distal 1.2 Mb, the gene density is typical of euchromatin, and this region i...

Enterohemorragic Escherichia coli strains (EHEC) represent an important problem for public health in developed countries. Indeed, EHEC strains can infect humans via vegetal and animal food consumption and cause food poisoning with diarrhoeas, frequently accompanied by hemorrhagic colitis with, in 10 % of the cases, apparition of renal sequelae (Haemolytic Uraemic Syndrome) that can lead to deat...

The synergy between the reflected solar spectrum (Visible Near Infrared/ Short Wave Infrared or VSWIR) and the emitted spectrum (Thermal Infrared or TIR) for identifying plant species’ foliar chemistry has been largely unexplored. In the 2013 spring and summer seasons, fresh leaves from sixteen common shrub and tree species were sampled from locations ranging from the Sierra Nevada mountains, t...

Background: Infection with Escherichia coli O157:H7 rarely leads to bloody diarrhea and causes hemolytic uremic syndrome with renal failure that can be deadly dangerous. Intimin, translocated Intimin receptor (Tir), and enterohemorrhagic E. coli (EHEC) secreted protein A (EspA) proteins are the virulence factors expressed by locus of enterocyte effacement locus of EHEC. This bacterium needs Es...

This paper describes the overview of NTCIR-11 Temporal Information Access (Temporalia) task. This pilot task aims to foster research in temporal aspects of information retrieval and search. Temporalia is composed of two subtasks: Temporal Query Intent Classification (TQIC) and Temporal Information Retrieval (TIR) subtask. TQIC attracted 6 teams which submitted a total of 17 runs, while 6 teams ...

Finite-length delay-optimized multi-input multi-output (MIMO) equalizers that optimally shorten the impulse response memory of frequency-selective MIMO channels are derived. The MIMO equalizers are designed to minimize the average energy of the error sequence between the equalized MIMO channel impulse response and an MIMO target impulse response (TIR) with shorter memory. Two criteria for optim...

Type 3 secretion systems (T3SSs) are utilized by pathogenic Escherichia coli to infect their hosts and many proteins from these systems are affected by chaperones specific to T3SS-containing bacteria. Toward developing a recombinant vaccine against enterohaemorrhagic E. coli (EHEC), we expressed recombinant T3SS and related proteins from predominant EHEC serotypes in Nicotiana chloroplasts. Nic...

We present TIR-PTD spectroscopy, an IR-pump/VIS-probe method for the measurement of IR absorption spectra by means of photothermal deflectometry (PTD) enhanced by total internal reflection (TIR). It overcomes the limitations of IR spectroscopy for the study of opaque samples and allows molecular fingerprinting of IR-active liquids or solids. Another important advantage of the presented approach...
