Wire bonding a die to a package has traditionally been performed using either aluminum or gold wire. Gold wire provides the ability to use a ball and stitch process. This technique provides more control over loop height and bond placement. The drawback has been the increasing cost of the gold wire. Lower cost Al wire has been used for wedgewedge bonds but these are not as versatile for complex ...

An atom attached to a micrometer-scale wire that is vibrating at a frequency ∼100 MHz and with displacement amplitude ∼1 nm experiences an acceleration magnitude ∼109 m s−2, approaching the surface gravity of a neutron star. As one application of such extreme noninertial forces in a mesoscopic setting, we consider a model two-path atom interferometer with one path consisting of the 100 MHz vibr...

A few previous reports have described cases wherein electrical wire cables were inserted into the male urethra and bladder. Electrical wire cables are available at home and are easy to insert. However, after they coil in the patient's bladder, they are difficult to remove. In February 2013, a 30-year-old man presented to the emergency room of SMG-SNU Boramae Medical Center with a urethral forei...

The effectiveness evaluation of flexible intramedullary nailing (FIN) and kirschner wire fixation (K-wire) used for MDJ fractures fixation have been described in multiple reports. But there have been few reports about comparison between FIN and K-wire in children with distal humeral MDJ fracture. In our retrospective study, Nineteen children received K-wire and twenty children received FIN, dur...

OBJECTIVE To determine potential effects of humidification on the volume of airway secretions in mechanically ventilated patients. METHODS Water vapor delivery from devices providing non-heated-wire humidification, heated-wire humidification, and heat and moisture exchanger (HME) were quantified on the bench. Then, patients requiring 24-hour mechanical ventilation were exposed sequentially to...

A polar coding scheme is introduced in this paper for the wire-tap channel. It is shown that the provided scheme achieves the entire rate-equivocation region for the case of symmetric and degraded wire-tap channel, where the weak notion of secrecy is assumed. For the particular case of binary erasure wire-tap channel, an alternative proof is given. The case of general non-degraded wire-tap chan...

Standard surgical repair of an intertrochanteric fracture, the most common hip fracture, requires accurate placement of a wire across the fracture using static fluoroscopic images. Wire navigation is fundamental to a number of orthopedic procedures. Directing and advancing the wire in the correct plane relies on both visual-spatial and psychomotor dexterity skills [1]. Underdeveloped skills cau...
