No surgery on a non-torus 2-bridge knot yields a reducible 3-manifold as shown in Theorem 2(a) in [7] by A. Hatcher and W. Thurston. Dehn surgeries on 2-bridge knots are already well studied by M. Brittenham and Y.-Q. Wu in [2]. See also [11]. On 2-bridge links of 2-components, Wu showed in [13, Theorem 5.1 and Remark 5.5] the following theorem. The universal covering space of a laminar 3-manif...

A diagonal surface in a link exterior M is a properly embedded, incompressible, boundary incompressible surface which furthermore has the same number of boundary components and same slope on each component of ∂M . We derive a formula for the boundary slope of a diagonal surface in the exterior of a 2-bridge link which is analogous to the formula for the boundary slope of a 2-bridge knot found b...

After anaphase onset, animal cells build an actomyosin contractile ring that constricts the plasma membrane to generate two daughter cells connected by a cytoplasmic bridge. The bridge is ultimately severed to complete cytokinesis. Myriad techniques have been used to identify proteins that participate in cytokinesis in vertebrates, insects, and nematodes. A conserved core of about 20 proteins a...

A new high-sensitive magnetic sensor which is referred to a symmetric response magnetoresistance (SRMR) proposed. This uses giant (GMR) elements have field response. An ac with frequency f applied the GMR in order modulate small detecting field. Due of MR element, carrier signal converted 2f and . By using full bridge circuit, where two pairs opposite phase field, components can be eliminated a...

general kind of encroachment of river is constructing a bridge on it. purpose of encroachment of river is occupation part of river and flood plain for constructing bridge. often being economical of bridge innovation affirmated that most of encroachment take place to river and flood plain, which this encroachment can be in form of embankment in flood plain of river or into the main bed of river ...

Rapidly deployable mobile bridges are of direct relevance to military and civilian agencies. The US Army uses such bridges in a broad range of applications including assault, tactical, and general communication. Civilian use extends from temporary infrastructure improvements during natural disasters to planned situations that are equally critical. This paper describes a modular bridge system de...

Continuous rigid frame bridge is a common type of bridge in California, where is a seismically active areas. Main structural features of the bridge, including asymmetry, hinge structure, concretion of girder and piers affect the seismic response of the bridge significantly. In order to evaluate the safety of the bridge under earthquake, the nonlinear models of girder, limiting steels in hinge, ...

This work is dedicated to constructing a multi-scale structural health monitoring system to monitor and evaluate the serviceability of bridges based on the Hadoop Ecosystem (MS-SHM-Hadoop). By taking the advantages of the fault-tolerant distributed file system called the Hadoop Distributed File System (HDFS) and high-performance parallel data processing engine called MapReduce programming parad...

Heavy movable bridges have different design, operation and maintenance characteristics compared to fixed bridges. This is mainly due to the complex interaction between their structural, mechanical and electrical systems. Movable bridges are viable options in certain terrain conditions and their unique operation provides versatility. At the same time, their intricate interrelation also produces ...
