A modified version of the standard A.L.F DNA sequencer (Pharmacia, Uppsala) is described that allows the separation of up to 1000 bases per clone. Fragments were resolved at single peak resolution up to 700 bases. The raw data accuracy was >99.7%, resulting in an overall error rate of <0.01% for the final sequence after sequencing both DNA strands. The modifications include 60 cm thermostatic a...
Abstract—In this paper, a planar monopole antenna for UltraWideband (UWB) communications with a notched behavior in the two sub-bands UNII1 and UNII2 of the Wireless Local Area Network (WLAN) band is presented. The antenna geometry is described by means of a spline curve and a rectangular slot. Numerical and experimental results are reported to assess the effectiveness of the proposed design in...
Using molecular dynamics with an accurate many-body potential for metallic Tantalum, we studied crack propagation in a pre-notched nano-slab under uniaxial strain in a [100] direction. We study dislocation emission from the crack tip for various strain rate and temperatures, focusing on the influence of the local temperature at the crack tip on the propagation of the crack. We find a close conn...
Serial electrocardiographic (E.C.G.) recordings were taken in seven patients suffering from intracranial conditions, for which their intracranial pressure was directly and continuously monitored with a Konigsberg extradural transducer. The E.C.G. changes observed in patients with raised intracranial pressure were prominent U waves, ST-T segment changes, notched T waves, and shortening and prolo...
In this study, the fatigue behavior of composite patched and non-patched Al 5083 aluminum plates was numerically investigated. Aluminum with semi-circular notched (2, 3 4 mm long cracked) "V" (30°, 45° 60° angled) were used in analyzes. Mechanical properties plate, DP460 type adhesive produced by 3M [0°]8 glass fiber reinforced patch material for study. The Finite Element Method applied numeric...
A 55 year old male with a history of frequent symptomatic episodes of paroxysmal atrial fibrillation (AF) for four years was referred to us for catheter ablation. He had earlier tried flecainide and sotalol. However he was unresponsive to both of them. The echocardiogram was normal. Figure 1, left panel demonstrates his baseline electrocardiogram. The relatively slow rate and regularity of this...
A 69-year-old Korean man was admitted to emergency room with complaints of abdominal pain, vomiting, and diarrhea. Laboratory tests revealed eosinophilia, anemia, hypoproteinemia, and hyponatremia. The gastric mucosa showed whitish mottled and slightly elevated lesions on the body angle of antrum. Microscopically, chronic gastritis with incomplete intestinal metaplasia was observed. Many adult ...
The fatigue behaviour of injection moulded short fibre reinforced polymers depends upon fibre orientation, as shown in experiments conducted with notched specimens injected through different injection gates. The different fatigue behaviour is related to the different local elastic properties, as determined by the different fibre orientation patterns, resulting into different strain distribution...
Two kinds of band-notched ultra wide-band slot antennas are proposed. Printed on a dielectric substrate of FR4 with relative permittivity of 4.4 and fed by a 50 Ω microstrip line, the proposed antennas introduce semicircular annular strips to reject the frequency band (5.15–5.85 GHz) limited by IEEE802.11a. The parameters which affect the performance of the antennas in terms of its frequency do...
