251 Mathews, V. JohnAdaptive, quadratic preprocessing of document images for binarizationAbstract-This paper presents an adaptive algorithm for preprocessing document images prior to binarization in character recognition problems. Our method is similar in its approach to the blind adaptive equalization of binary communication channels. The adaptive filter utilizes a quadratic system mod...1998
252 Beckerle, Mary C.Adhesion plaque protein, talin, is phosphorylated in vivo in chicken embryo fibroblasts exposed to the tumor-promoting phorbol esterTalin is a high molecular weight phosphoprotein that is localized at adhesion plaques. We have found that talin phosphorylation increases 3.0-fold upon exposure of chicken embryo fibroblasts to the tumor-promoting phorbol ester, phorbol 12-myristate 13-acetate.Talin; Vinculin; Chicken embryo fibroblasts1990
253 Symko, Orest GeorgeAdiabatic compressional cooling of He3By adiabatic compression of a two-phase mixture of liquid and solid He3, temperatures below 2.5 mK have been obtained. These are in the range expected for nuclear ordering in solid He3.He3; Adiabatic compressional cooling1969-03
254 Kestle, John R. W.; Walker, Marion L.Adjustment and malfunction of a programmable valve after exposure to toy magnetsInadvertent adjustments and malfunctions of programmable valves have been reported in cases in which patients have encountered powerful electromagnetic fields such as those involved in magnetic resonance imaging, but the effects of small magnetic fields are not well known. The authors present a ca...2004
255 McDaniel, SusanAdoption in Canada: A neglected area of data collection and researchFor some decades there has been in Canada, as in the United States, recurrent public interest in adoption. At various times this interest has been kindled by professional concern about unauthorized child placement and by the plight of children made homeless by war and other calamities. More recently...Canada; Adoption; Statistics1981
256 McDaniel, SusanAdoption policy in Great Britain and North AmericaThis paper has two purposes. First, to explore what existing adoption legislation may indicate about the meaning and function of adoption practices in North America and Great Britain. Second, to consider some possible policy implications revealed by clearer understanding of the social meaning of exi...Adoption law; Family; North America1984
257 Stringfellow, Gerald B.; Shurtleff, James KevinAdsorption and desorption of the surfactant Sb on GaInP grown by organometallic vapor phase epitaxyIt has been determined that ordering has a profound effect on the bandgap energy of many compound semiconductor alloys. Therefore, ordering must be controlled for devices such as solar cells, light emitting diodes and diode lasers. Since ordering depends on the surface properties during organomet...Time dependent surface photoabsorption (SPA); Compound semiconductor alloys2000
258 Miller, Jan D.Adsorption mechanisms in nonmetallic activation systemsAdsorption of lead and ferric iron on quurtz and alumina is presented as a function of pH. Only the hydrolyzed species of these metal ions, FeOHt+ and PbOH', adsorb significantly on each of these minerals. Zeta potentials of quartz were measured as a function of pH in the presence of various additio...Ferric iron; Quartz; Lead; Alumina; Adsorption; pH (Chemistry)1970
259 Normann, Richard A.; Jones, Kelly E.Advanced demultiplexing system for physiological stimulationA CMOS very large scale integration (VLSI) chip has been designed and built to implement a scheme developed for multiplexing/demultiplexing the signals required to operate an intracortical stimulating electrode array. Because the use of radio telemetry in a proposed system utilizing this chip may im...Electrode Array; Stimulation; Telemetry; Microelectrodes; Transistors1997
260 Williams, Clayton C.Advances in experimental technique for quantitative two dimensional dopant profiling by scanning capacitance microscopySeveral advances have been made toward the achievement of quantitative two-dimensional dopant and carrier profiling. To improve the dielectric and charge properties of the oxide-silicon interface, a method of low temperature heat treatment has been developed which produces an insulating layer with c...Doping; Scanning capacitance microscope; SCM1999
261 Martin, JimAerodynamic drag area of cyclists determined with field-based measuresAerodynamic drag is an important factor in the performance of competitive track and road cyclists. Recently we used wind-tunnel testing to validate a practical measure of aerodynamic drag derived from a field test. We present here instructions for performing the field test on a straight flat road or...2006-01-01
262 Hawkes, KristenAffluent hunters? Some comments in light of the Alyawara caseOur recent analysis (O'Connell and Hawkes in press) of plant food collecting among the Alyawara, a central Australian hunting group, shows that the cost of subsistence is sometimes quite high, far higher than the current conven. tional wisdom regarding hunters would suggest. We infer from available ...1981-01-01
263 Li, MinqiAfter neoliberalism: empire, social democracy, or socialism?Analyzes political doctrines such as imperialism, social democracy and socialism as a possible economic trend after the neoliberalism era.

264 Gondolo, PaoloAGAPE, a microlensing search in the direction of M31: status reportThe M31 galaxy in Andromeda is the nearest large galaxy after the Small and Large Magellanic Clouds. It is a giant galaxy, roughly 2 times as large as our Milky Way, and has its own halo. As pointed by some of us [1, 2] and independantly by A. Crotts [3], M31 provides a rich field of stars to searc...AGAPE; Andromeda Gravitational Amplification Pixel Experiment; Microlensing; MACHO; Massive compact halo objects1995
265 Gondolo, PaoloAGAPE: a search for dark matter in M31 by microlensing effects on unresolved starsM 31 is a very tempting target for a microlensing search of compact objects in galactic haloes. It is the nearest large galaxy, it probably has its own dark halo, and its tilted position with respect to the line of sight provides an unmistakable signature of microlensing. However most stars of M 31...M31; AGAPE; Pixel method; Galaxy; Halo; Cosmology; Gravitational lensing1997
266 Gondolo, PaoloAGAPE: andromeda gravitational amplification pixel experimentThe aim of the AGAPE (Andromeda Gravitational Ampli_x000C_cation Pixel Experiment), experiment which has been _x000C_rst proposed in June 1992 is to examine the distribution of massive astrophysical compact halo objects ((MACHO's) which possibly are in the galactic haloes and which could account for...AGAPE; Andromeda Gravitational Amplification Pixel Experiment; Microlensing; MACHO; Massive compact halo objects1997
267 Gondolo, PaoloAGAPEROS: searching for microlensing in the LMC with the pixel method. I. Data treatment and pixel light curves productionRecent surveys monitoring millions of light curves of resolved stars in the LMC have discovered several microlensing events. Unresolved stars could however signi _x000C_cantly contribute to the microlensing rate towards the LMC. Monitoring pixels, as opposed to individual stars, should be able to ...Data analysis techniques; Halo; Galaxies; Gravitational lensing; Pixel method; Large Magellanic Cloud; LMC1999
268 Gondolo, PaoloAgapeZ1: a large amplification microlensing event or an odd variable star towards the inner bulge of M31AgapeZ1 is the brightest and the shortest duration microlensing candidate event found to date in the Agape experiment. It occurred only 4200 from the centre of M31 at RA = 0h42m41:47s and Dec = 41°16'39.1" (J2000). Our photometry shows that the half intensity duration of the event is 5.3 days and ...AgapeZ1; Galaxy; Halo; Cosmology; Gravitational lensing; M31; Pixel method1999
269 Battin, Margaret P.Age rationing and the just distribution of health care: is there a duty to die?These lines express a view again stirring controversy: that the elderly who are irreversibly ill, whose lives can be continued only with substantial medical support, ought not to be given treatment; instead, their lives should be brought to an end. It should be recognized, as one contemporary politi...1987
270 Battin, Margaret P.Age-rationing and the just distribution of health care: Is there a duty to die?The author analyzes the argument that a policy involving distributive justice in the allocation of scarce health care resources, based on the strategy of rational self interest maximation under a veil of ignorance (Rawls/Daniels), would result in an age rationing system of voluntary, socially encour...Health care providers; Death; Euthanasia1987-01
