Fast long lived renaming
The long-lived renaming problem appears in shared-memory systems where a set of threads need to register and deregister frequently from the computation, while concurrent operations scan the set of currently registered threads. Instances of this problem show up in concurrent implementations of …

Long-lived mesoscale convective systems over Eastern South Africa
… with there being little evidence of any long-term climatology studies of these systems over the region. A climatology of large, long-lived MCSs over eastern South Africa for the extended austral summer (September-April) from 1985-2008 is presented. On average, 63 MCSs occur here in …

Long lived states induced by extended illumination of carbonmonoxy-myoglobin
… slow down. The proteins are ""pumped"" to longer lived states. After waiting, the system resets, such that a photodissociation initiates regular, non-pumped, kinetics. I have measured the kinetics of the ""pumped"" states and the time course of the resetting, at various temperatures. …

Long-lived states induced by extended illumination of carbonmonoxy-myoglobin
Myoglobin is a heme-protein that binds small ligands, such as O$\sb2$ and CO. A photon of visible light absorbed by the protein can break the protein ligand bond. At low temperatures ($>$160K) the kinetics of recombination of photodissociated carbonmonoxy-myoglobin are non-exponential, having …

Experimental Investigation of Long-Lived "ZEKE" Rydberg States in Ultracold Argon
… ZEKE Rydberg states live orders of magnitude longer than low angular momentum states. We are reporting on our experimental investigation of these states in the ultracold regime and prospects for future studies in which external control of these states may be used to control ultracold plasma …

Probing the protein homeostasis mechanisms in long-lived naked mole-rats
… inhabitation and poikilothermy. It is the longest-living rodent, showing negligible senescence over the majority of its lifespan and high resistance to diseases such as cancer and neurodegeneration. This animal is therefore a compelling system for understanding ageing and age-related …

Studies Directed to the Development of Long Lived Palladium Membranes for Hydrogen Purification
<p>The focus of this study was to systematically investigate the variables involved in electroless deposition of palladium and palladium alloy membranes on a known porous stainless steel substrate, and apply the results to a new and novel porous stainless steel substrate. Different oxide pore and …

Genetic effects of persistent population bottlenecks on long-lived organisms with overlapping generations
… complexities when applying the models to long-lived organisms. This study developed an overlapping-generation model to study the genetic consequence of bottlenecks in long-lived organisms. This model is implemented in a computer simulation program, BottleSim, to serve as a tool to evaluate …

Dusty gust fronts and their contributions to long-lived convection in West Africa/
… to track these fronts' propagation over a much longer distance than the <80 km enabled by radar; gust fronts are shown to propagate over >1000 km (mean 750 km) and up to 24 hours, much further than has been previously demonstrated for large numbers of gust fronts. These gust fronts are often …

Searching for signs of hidden sectors at the LHC: long-lived particle methods and models
… These questions are solved in theories of new long-lived particles (LLPs) in hidden sectors, but in practice the current search program may miss key data, especially for MeV-GeV range masses of transverse-boosted LLPs. The high-luminosity Large Hadron Collider (HL-LHC) will produce more data …

Folding, stability and aggregation of the long-lived eye lens protein human gamma D crystallin
Human [gamma]D crystallin (H[gamma]D-Crys) is a monomeric, two domain, primarily P-sheet protein found in high concentrations in the human eye lens. H[gamma]D-Crys and other crystallins are found in insoluble protein inclusions associated with the eye disease cataract. H[gamma]D-Crys is expressed …

A Potential Long-lived Upper Cretaceous Paleodrainage System In The U.s. Southwestern Georgia-southeastern Alabama Region
… Piedmont-eastern Blue Ridge terranes. Mapping along the Coastal Plain unconformity near the Lower Chattahoochee River Valley indicates the presence of one or more large paleovalleys in the Upper Cretaceous sub-Coastal Plain surface that occupy a similar position to a paleodrainage system …

Population biology, dynamics and their implications for management of red bass: a large, long-lived reef fish
… identified that this species was potentially long-lived and slow-growing. Knowing this, the harvest of L. bohar by commercial fisheries is a cause for concern because populations of long-lived, slow growing species are typically more vulnerable to overfishing (e.g. Adams 1980; Musick 1999). …

Telomere Dynamics of Grey Seals (Halichoerus grypus) on Sable Island, Nova Scotia: a Long-Lived Marine Mammal Population Island
… with age is well documented, but rarely in long-lived mammals due to sampling difficulty. This study used an established qPCR assay to measure relative telomere length (rTL) in the grey seals (Halichoerus grypus) of Sable Island, Nova Scotia, a population of long-lived marine mammals …

A Search for Neutral Long-Lived Particles Decaying into Displaced Jets in the ATLAS Calorimeter in Proton-Proton Collisions at the LHC
A search for neutral long-lived particles (LLPs) decaying in the ATLAS hadronic calorimeter using 140 fb^-1 of proton proton collisions at √s = 13 TeV delivered by the LHC is presented. The analysis targets pair-produced LLPs where at least one LLP is produced with sufficiently low boost that its …

Observation of upsilon suppression, search for long-lived particles, and observation of B0s → micro + micro-- at the LHC with the CMS experiment
… In Chapter 5, a search is performed for long-lived particles decaying to a final state that includes a pair of leptons. The experimental signature is a distinctive topology consisting of a pair of charged leptons originating from a displaced secondary vertex. Events were collected with …
