101 Capecchi, Mario R.Personal view of gene targetingGene targeting provides the means for creating strains of mice with mutations in virtually any gene.1 First, the desired mutation is introduced into a cloned copy of the chosen gene by standard recombinant DNA technology. The mutation is then transferred to the genome of a pluripotent mouse embryo-d...1995
102 Horch, Kenneth W.Perspectives on new electrode technology for stimulating peripheral nerves with implantable motor prosthesesAbstract-The limits of present electrode technology are being reached in current motor prostheses for restoring functional movement in paralyzed people. Improved devices require electrodes and stimulation methods that will activate muscles selectively and independently with less implanted hardwa...Paralysis; Prostheses; Electrodes1995
103 Vardeny, Zeev ValentinePhotoresponse and electroresponse of polymers light emitting diodesWe have studied the photoresponse and electroresponse of light emitting diodes (LEDs ) made from a variety of soluble conducting polymers sandwiched between indium tin oxide (ITO) and metals including calcium, aluminum and copper.

105 Brunvand, Erik L.Precise exception handling for a self-timed processorSelf-timed systems structured as multiple concurrent processes and communicating through self-timed queues are a convenient way to implement decoupled computer architectures.

108 Orr, Douglas B.Program specialization using the OMOS systemAbstraction and modularity provide many software engineering benefits. Hiding details of module internals can, however, prevent system implementors from being able to provide anything but a highly general implementation of a given module. We describe OMOS, a programmable linker/loader and system s...OMOS system; Program specialization; Modularity; Linker/loader; Modules1995
109 Williams, Clayton C.; Huang, YufengQuantitative two-dimensional dopant profile measurement and inverse modeling by scanning capacitance microscopyQuantitative dopant profile measurements are performed on a nanometer scale by scanning capacitance microscopy (SCM). An atomic force microscope is used to position a nanometer scale tip at a semiconductor surface, and local capacitance change is measured as a function of sample bias. A new feedback...Dopant profile; Capacitance change; Scanning capacitance microscopy; Feedback control1995
110 Carter, John B.Reducing consistency traffic and cache misses in the avalanche multiprocessorFor a parallel architecture to scale effectively, communication latency between processors must be avoided. We have found that the source of a large number of avoidable cache misses is the use of hardwired write-invalidate coherency protocols, which often exhibit high cache miss rates due to exces...Consistency traffic; Cache misses; Parallel architecture; Communication latency1995
111 Kestle, John R. W.Reduction of hemorrhage risk after stereotactic radiosurgery for cavernous malformationsThe benefits of radiosurgery for cavernous malformations are difficult to assess because of the unclear natural history of this vascular lesion, the inability to image malformation vessels, and the lack of an imaging technique that defines "cure." The authors selected for radiosurgery 47 patients w...Cavernous malformation; Gamma knife; Stereotactic radiosurgery1995
112 Kestle, John R. W.Relationship of intraoperative electrophysiological criteria to outcome after selective functional posterior rhizotomyAt British Columbia's Children's Hospital, the criteria used in selective functional posterior rhizotomy (SFPR) evolved in three distinct phases. In Phase 1 the electrophysiological criteria for abnormality included a low threshold to a single stimulation, a sustained response to 50-Hz stimulation, ...Selective posterior rhizotomy; Electrophysiological criteria; Intraoperative electrical stimulation1995
113 Zhdanov, MichaelResistivity imaging by time domain electromagnetic migration (TDEMM)One of the most challenging problems of electrical geophysical methods is the interpretation of time domain electromagnetic (TDEM) sounding data in the areas with the horizontally inhomogeneous geoelectrical structures. This problem is of utmost importance in mining exploration and environmental stu...1995
114 Diener, Marissa L.Role of prenatal expectations in parents' reports of infant temperamentThe associations were examined among parents' characteristics, their prenatal expectations for and postpartum perceptions of infant temperament, and observers' ratings of temperament. During pregnancy and at 3 months postpartum, 70 primiparous women and their husbands completed several mood and anx...1995
115 Sobh, Tarek M.Sensor-based distributed control scheme for mobile robotsIn this paper we present a sensor-based distributed control scheme for mobile robots. This scheme combines centralized and decentralized control strategies. A server-client model is used to implement this scheme where the server is a process that caries out the commands to be executed, and each clie...Sensor-based; Distributed control scheme1995

117 Hibler, Michael J.Separating presentation from interface in RPC and IDLsIn RPC-based communication, we term the interface the set of remote procedures and the types of their arguments; the presentation is the way these procedures and types are mapped to the target language environment in a particular client or server, including semantic requirements. For example, pres...RPC-based communication; IDL; Presentation; Interface1995
118 Williams, Clayton C.Shear force microscopy with capacitance detection for near-field scanning optical microscopyShear force microscopy is very useful for distance regulation in near-field scanning optical microscopy (NSOM). However, the optical method used to detect the shear force can cause problems when imaging photosensitive materials, i.e., the shear force detection beam can optically pump the sample. We ...Shear force microscopy; Atom force microscope; AFM; Capacitance sensing1995
119 Kestle, John R. W.Simple risk predictions for arteriovenous malformation hemorrhageWE PRESENT A simple risk prediction formula for arteriovenous malformation hemorrhage.

123 Stringfellow, Gerald B.Surface photo-absorption studies of the chemical structure of GaInP grown by organometallic vapor phase epitaxyThe surface structure of Ga0.52In0.48P was studied by surface photoabsorption. An absorption peak due to P dimers on Ga0.52In0.48P was observed at 400 nm, shorter than for InP (430 nm). From comparison with results for GaAs and InP, the data are interpreted to indicate that at a tertiarybutylphos...Absorption peak; Ordering; Substrate orientation1995
