A striking and unexpected biochemical phenotype was found in an insertion mutant line in the model plant Arabidopsis thaliana. One of two investigated insertion mutant lines in the gene encoding the phosphate transporter PHT4;1 demonstrated a prominent loss of trienoic fatty acids, whereas the other insertion line was indistinguishable from wild type in this aspect. We demonstrate that the loss...

Cochlear implants have become a standard treatment for many with severe to profound sensorineural hearing loss. However, delicate cochlear structures can be damaged during surgical insertion, which can lead to loss of residual hearing and decreased implant effectiveness. We propose a magnetic guidance concept in which a magnetically tipped cochlear implant is guided as it is inserted into the c...

This paper reports an Ultra wideband pass filter with a center frequency of 3.96 GHz and 3 dB bandwidth of 1584 MHz. The filter design is based on transversal signal interference principle implemented by means of transmission lines.The features of this filter include low insertion loss, sharp rejection along with simple design approach. Also, comparison of simulation and measured filter paramet...

This paper reports our progress in developing parallel coupled-line filters based on Si-based VLSI backend interconnects for millimeter-wave applications. The resonant frequency of this coupled-line filter increases with increasing spacing-gap and with increasing IDM thickness. By using high resistivity substrate, the parallel coupled-line band-pass filter is extremely effective in reducing sub...

Abstract A proposed schematic design for surface acoustic wave resonator (SAWR) is introduced in this paper. A simplified equivalent model for both one and two port 433MHz SAWR is built. Scattering parameters of the proposed design is extracted and compared with a commercial one of the same resonant frequency. Advanced system design tool is nominated to give the main parameters like Impedance a...

Attenuation characteristics of a planar silicon-clad ion exchange glass waveguide structure are investigated theoretically at the optical wavelength of 0.6328 μm. An oscillatory behaviour of the attenuation curves is noticed in the proposed four layer structure. It is observed that by varying the thickness of silicon cladding layer, the TE or TM propagating modes may be selectively attenuated. ...

Ochrobactrum intermedium is an opportunistic human pathogen belonging to the alpha 2 subgroup of proteobacteria. The 16S rDNA sequences of nine O. intermedium isolates from a collection of clinical and environmental isolates exhibited a 46-bp insertion at position 187, which was present in only one sequence among the 82 complete or partial 16S rDNA sequences of Ochrobactrum spp. available in da...

Recently, the demand for communication has been growing rapidly. Hence, optical multistage network technologies are more appreciated nowadays. A double-layer network is a strictly nonblocking network, and it has the lowest system insertion loss of nondilated networks. A Beneš network is a rearrangeably nonblocking network, and it has the same system insertion loss as a double-layer network. We ...

OBJECTIVE The aim of this study was to evaluate changes in bone conduction thresholds before, during and after total stapedectomy. STUDY DESIGN Prospective clinical study. METHODS In 27 ears of 26 patients undergoing stapedectomy under local anesthesia, bone conduction was measured before surgery, during surgery under open oval window conditions, and after the insertion of a steel wire conn...

Neuromuscular block results in the loss of muscular tone in the upper airway, which might contribute to the increased postoperative airway morbidity followed by ProSeal laryngeal mask airway (PLMA) insertion. We compared the pharyngolaryngeal discomfort exerted by the PLMA according to the neuromuscular block. One hundred sixty patients undergoing surgery for breast disease or inguinal hernia w...
