| 976 |  | Baehr, Wolfgang | Calcium-sensitive regions of GCAP1 as observed by chemical modifications, fluorescence, and EPR spectroscopies | Guanylyl cyclase-activating proteins are EF-hand Ca(2+)-binding proteins that belong to the calmodulin superfamily. They are involved in the regulation of photoreceptor membrane-associated guanylyl cyclases that produce cGMP, a second messenger of vertebrate vision. Here, we investigated changes in ... | Amino Acid Motifs; Cyclic N-Oxides; EF Hand Motifs | 2001 |

| 983 |  | McElreath, Richard | Can females gain additional paternal investment by mating with multiple males? a game theoretic approach | Although females may require only one mating to become inseminated, many female animals engage in costly mating with multiple males. One potential benefit of polyandrous mating is gaining parental investment from multiple males. We developed two game theoretic models to explore this possibility. Our... | Female multiple mating; Polyandry; Nonprocreative mating; Paternal investment; Mating benefits; Mating strategy | 2001-11 |

| 985 |  | Codding, Brian F.; Robert, Heidi; Eckerle, William; Brewer, Simon C.; Medina, Ishmael; Vemon, Kenneth Blake; & Spangler, Jerry S. | Can we reliably detect adaptive responses of hunter-gatherers to past climate change? Examining the impact of Mid-Holocene drought on Archaic settlement in the Basin-Plateau Region of North America | Climatic change appears to influence major patterns in human history. However, confirming the association between climatic events and adaptive human responses is not straightforward given the potential for spurious correlations and uncertainty in the timing of events. Here we leverage theory from be... | behavioral ecology; climate change resilience; environmental archaeology; dates as data | 2024 |
| 986 |  | Gondolo, Paolo | Can WIMP spin dependent couplings explain DAMA data, in light of null results from other experiments? | We examine whether the annual modulation found by the DAMA dark matter experiment can be explained by Weakly Interacting Massive Particles (WIMPs), in light of new null results from other experiments. CDMS II has already ruled out most WIMP-nucleus spin-independent couplings as an explanation for DA... | WIMP; Weakly interacting massive particles; DAMA; CDMS II; Parameter space | 2004-12 |
| 987 |  | Chuaqui, Miguel Basim | Canto Repartido | El Canto Repartido (The Shared Out Song) takes its title from a poem in the collection Las Uvas y el Viento (The Grapes and the Wind) by the Chilean poet Pablo Neruda.

| 988 |  | Bhanu, Bir | CAOS an approach to robot control | Control systems which enable robots to behave intelligently is a major issue in todays process of automating factories.

| 989 |  | Furse, Cynthia M. | Capacitance and inductance sensor circuits for detecting the lengths of open- and short-circuited wires | The length of an open- or short-circuited wire is linearly proportional to the capacitance or inductance of the wire, respectively. Several types of simple and inexpensive circuits are introduced to measure these values. Open-circuited (capacitance) measurements are very effective. Short-circuited ... | Aging aircraft wire; Capacitance sensors; Fault detection; Inductance sensors | 2009-08 |
| 990 |  | Stevens, Kenneth | Capacitive ionic current measurement in a polymer-electrolyte transistor | Organic transistors that use dissolved ions to conduct current are able to reproduce the current-voltage characteristics of semiconductor transistors.

| 991 |  | Friedrich, Frances | Capacity demands of automatic processes in semantic priming | In three experiments, we examined the effects of prime-target stimulus onset asynchrony (SSA) and the proportion of related primes and targets (relatedness proportion, or RP) on semantic priming when the prime was either named or was searched for a specific letter . In Experiment 1, with an RP of .... | Semantic priming; stimulus onset asynchrony | 1994 |
| 992 |  | Miller, Jan D.; Lin, Chen-Luh | Capillary network model for filter cake based on pore structure analysis | Dewatering of fine coal by continuous filtration involves filter cake formation and removal of surface moisture by drawing air through the capillaries of the cake.

| 993 |  | Thalos, Mariam G. | Capitalization in the St. Petersburg Game: why statistical distributions matter | In spite of its infinite expectation value, the St. Petersburg game is not only a gamble without supply in the real world, but also one without demand at apparently very reasonable asking prices. We offer a rationalizing explanation of why the St. Petersburg bargain is unattractive on both sides (to... | 2013-01-01 | |
| 994 |  | Jorgensen, Erik; Schuske, Kimberly R. | CAPS and syntaxin dock dense core vesicles to the plasma membrane in neurons | Docking to the plasma membrane prepares vesicles for rapid release.

| 996 |  | Lighty, Joann; Sarofim, Adel F. | Carbon dioxide effects on metal vaporization during coal combustion | Coal combustion products may take one of two forms. Residual ash (> 1 micron) is formed by particle shrinkage and breaking during combustion. Some material will vaporize and later recondense. During recondensation, these molecules have a high affinity for submicron particles because of the large sur... | Coal combustion products; Metal vaporization; Carbon dioxide; Residual ash | 2001 |
| 997 |  | Ehleringer, James R. | Carbon isotope discrimination and water relations of oak hybrid populations in southwestern Utah | The evergreen oak Quercus turbinella and the deciduous Q. gambelii form natural hybrids in southwestern Utah and northern Arizona.
