Natural habitats are exposed to an increasing number of environmental stressors that cause important ecological consequences. However, the multifarious nature of environmental change, the strength and the relative timing of each stressor largely limit our understanding of biological responses to environmental change. In particular, early response to unpredictable environmental change, critical ...

Introduction: To investigate the effects of predictable and unpredictable external perturbations on cortical activity in healthy young and older adults. Methods: Twenty healthy older and 19 healthy young adults were exposed to predictable and unpredictable external perturbations, and their cortical activity upon postural recovery was measured using a 32-channel quantitative encephalography. Th...

One of primary reasons for the establishment of the ARM Southern Great Plains research site was to obtain long-term records of surface radiation data and the impact of clouds on these data (Stokes and Schwartz 1994). This research project focuses on the creation of a two-year climatology of the surface radiation budget and the impact of clouds on that budget. The period of analysis extends from...

Computational strain-design prediction accuracy has been the focus for many recent efforts through the selective integration of kinetic information into metabolic models. In general, kinetic model prediction quality is determined by the range and scope of genetic and/or environmental perturbations used during parameterization. In this effort, we apply the k-OptForce procedure on a kinetic model...

Genome-wide gene expression is re-programmed in response to external or internal factors such as environmental stress or genetic mutation, respectively, or as a function of endogenous processes such as cell proliferation or differentiation. Here we integrate expression profiling data that have been collected by our laboratory since 2001 and that interrogate more than 900 different experimental ...

Family businesses are an important factor for technological progress and high economic efficiency, determining a significant part of economic strength. At present, inside the European Monetary Union (EMU), there are efforts to reduce public debt to fulfill the criteria imposed by the Stability and Growth Pact (SGP), which are mandatory for members of the Euro zone. Due to these constraints, pub...

This paper present a study of the relationship between subglottal pressure (SGP) and intensity of the speech signal in the case of sustained French oral vowels with controlled pitch. The corpus is based on a male and a female subjects, the SGP is measured directly by tracheal puncture. The results show that the relationship between intensity and subglottal pressure varies when one considers the...

This paper introduces a new algorithm to detect aerosols and clouds based on micropulse lidar measurements. A semidiscretization processing technique is first used to inhibit the impact of increasing noise with distance. The value distribution equalization method which reduces the magnitude of signal variations with distance is then introduced. Combined with empirical threshold values, we deter...

The talk concerns minimax control problems for linear multidimensional parabolic systems with distributed uncertain perturbations and control functions acting in the Dirichlet boundary conditions. The underlying parabolic control system is functioning under hard/pointwise constraints on control and state variables. The main goal is to design a feedback control regulator that ensures the require...

Responses of shallow cumuli to large-scale temperature/moisture perturbations are examined through diagnostics of large-eddy simulations (LESs) of the undisturbed Barbados Oceanographic and Meteorological Experiment (BOMEX) case and a stochastic parcel model. The perturbations are added instantaneously and allowed to evolve freely afterward. The parcel model reproduces most of the changes in th...
