Adaptive strategy for one-sided communication in MPICH2
… we describe the design and implementation of an adaptive approach for all three synchronization mechanisms defined in MPI: fence, post-start-complete-wait, and lock-unlock. We evaluate our implementation with both micro benchmarks and the Graph500 benchmark to demonstrate the performance impact …

An adaptive strategy for providing dynamic route guidance under non-recurrent traffic congestion
… advantage of pursuing system optimal routing strategy, which is more essential under abnormal traffic conditions such as non-recurrent congestion and natural disaster. However user compliance could be a problem under such a strategy, particularly when some of equipped drivers are urged not to …

SHORT-CHAIN FATTY ACIDS INDUCED AUTOPHAGY SERVES AS AN ADAPTIVE STRATEGY FOR RETARDING MITOCHONDRIA-MEDIATED APOPTOTIC CELL DEATH
… that propionatetriggered autophagy serves as an adaptive strategy for retarding mitochondria-mediated apoptotic cell death, whereas application of an autophagy inhibitor (Chloroquine) is expected to enhance the therapeutic efficacy of SCFAs in inducing colon tumor cell apoptosis.

The Effects of Vegetation on Ecosystem Services Provisioning by Stormwater Bioretention
… suites of traits that reflect underlying plant adaptive strategies, emergent landscape-scale factors like pattern, and ecological attributes like nativeness. The first chap- ter reviews key topics like stormwater bioretention, ecosystem services provisioning, and vegetative characteristics …

Exploring Life History Strategies in Adolescence; Attachment, Personality, and Bullying
… of Evolutionary Theory, termed Life History Strategy (LHS), to the study of bullying. The current study aimed to highlight the relationship between environmental pressures, slow and fast LHS, and bullying subtypes. A sample of 261 participants (125 males and 135 females) between the ages of …

Nonadaptive lossy encoding of sparse signals
… a sparse signal is optimally encoded through an adaptive strategy that finds and encodes the signal's representation in the sparsity-inducing basis. This thesis examines how much the distortion rate (D(R)) performance of a nonadaptive encoder, one that is not allowed to explicitly specify the …

Stress and sociality in a patrilocal primate: Do female spider monkeys tend-and-befriend?
Stress provokes an adaptive strategy that mobilizes the body for acute physical challenges. However, chronic stress has detrimental effects that can reduce health and reproductive fitness. Thus, coping mechanisms are valuable in reducing chronic stress. One such mechanism, the “tend-and-befriend” …

Adaptive observations : idealized sampling strategies for improving numerical weather prediction
The purpose of adaptive observations is to use information about individual atmospheric situations to identify regions where additional observations are likely to improve weather forecasts of interest. The observation network could be adapted for a wide range of forecasting goals, and it could be …

Factors influencing equal-loudness level contours
… set-up on the results can be reduced using an adaptive procedure. By enhancing the complexity of the adaptive strategy, it is possible to minimize the effects of starting level on the resulting PSE. It is demonstrated that a procedure of four interleaved tracks is sufficient to gain …

Planning for the Future in the Face of Climate Change Uncertainty: Three Econometric Techniques Applied to the Challenges Facing Energy, Water, and Recreation Demand
… change. The first paper investigates a potential adaptive strategy to counteract warming stream waters through stream intervention projects. Using novel non-parametric matching estimation techniques it is shown that these intervention projects have positive effects on homeowners that are near to …

Water resource management by the ancient Maya of Yucatan, Mexico
… resource management on a regional scale as an adaptive strategy that enabled the ancient Maya to inhabit a seemingly forbidding environment. Using the latest computer technology, Geographic Information Systems, and Global Positioning System data collectors, we spent nine months gathering data …

Reproductive Biology of Alligator Snapping Turtles: Behavior, Reproductive Investment, and Nest Predation
… lacked visual stimuli. The conspicuous nesting strategy employed by M. temminckii is discussed as a potential evolutionarily adaptive strategy to disguise the exact location of the clutch from predators.

Multidimensional Quadrature
… The majority of the work is based upon an adaptive approach. One exception is a program which generates a sequence of product rules from the one dimensional Patterson family of formulae and applies these rules iteratively over a hypercube type region of integration. A basic adaptive …

Parallel Sparse Linear Algebra for Homotopy Methods
… with the sequence of such systems. The proposed adaptive strategy of GMRES(k) allows tuning of the restart parameter k based on the GMRES convergence rate for the given problem. Adaptive GMRES(k) is shown to be superior to several other iterative techniques on analog circuit simulation problems …

The physiological consequences of loss of tRNA thiolation in Saccharomyces cerevisiae
… This decrease in tRNA thiolation may be an adaptive strategy used by cells under specific growth conditions, and is an example of the condition specific modulation of tRNA modification levels

Disclosing new worlds? : Strategic management, styles and meaning
… of post-agile strategic practice, which I call adaptive, to address this loss. Consistent with Heideggerian philosophy, I utilise a transformative disclosure methodology and a literary, paradigmatic case reading method to address the questions: Why is agile strategic management so unsatisfying? …

Situational Affordances and Psychopathy: Examining Contextual Influences on Exploitative Behavior in Economic Games
… with the view that psychopathic traits are more adaptive in environments characterized by transient, short-term relationship but incur significant costs in environments characterized by stable, long-term relationships. In sum, this dissertation provides a nuanced understanding of psychopathy as a …

Autonomous wireless smart sensor for monitoring of railroad bridges
… remote data retrieval and post-processing. An adaptive strategy combining an event-based scheme, scheduled rendezvous framework, and preemptive multitasking operation is implemented in the proposed system. The robust monitoring strategy is designed to detect and monitor both train-crossing and …
