Modeling water flow in cropped soils: water uptake by plant roots
Environment International, 1995Co-Authors: T.c. Janz, R.j. StonierAbstract:Abstract The Richards' equation is used as the Basic Paradigm for water flow in unsaturated soils. An empirical sink term is included to represent the uptake of water by the plant roots. This sink term incorporates a concept termed Evaporation Front which represents the drying upper layers and the subsequent ineffectual roots in this zone during surface evaporation. The Richards' equation is solved numerically by expressing the model in finite-difference form using the Crank-Nicolson method. The resulting water profiles are compared with field data.

Its own reward: lessons to be drawn from the reversed-reward contingency Paradigm
Animal Cognition, 2009Co-Authors: Eran M. ShiffermanAbstract:This is a review of the reversed-reward contingency (RRC) Paradigm in animals and the cognitive functions on which it is founded. I shall present the RRC Basic Paradigm and the ensuing modifications it underwent, the animals tested, the results obtained and the analyses offered within the literature. Then I would the claim that RRC is a case of a compound cognitive behavior, one that is the result of interactions between three other cognitive functions: crude numerical assessment and economic choice (uniting value assignment and behavioral inhibition). I will present data concerning these three fields and will demonstrate how they are both affecting and affected by the findings of the RRC scheme. RRC is treated here as a test case for a broader type of analysis, one which, hopefully, will show that in order to fully understand composite and complex behavior we need to meticulously explore its building blocks and their dynamic interplay.

Protecting thermodynamic stability of protein: The Basic Paradigm against stress and unfolded protein response by osmolytes.
International journal of biological macromolecules, 2021Co-Authors: Gurumayum Suraj Sharma, Snigdha Krishna, Sheeza Khan, Tanveer Ali Dar, Khurshid Alam Khan, Laishram Rajendrakumar SinghAbstract:Organic osmolytes are known to play important role in stress protection by stabilizing macromolecules and suppressing harmful effects on functional activity. There is existence of several reports in the literature regarding their effects on structural, functional and thermodynamic aspects of many enzymes and the interaction parameters with proteins have been explored. Osmolytes are compatible with enzyme function and therefore, can be accumulated up to several millimolar concentrations. From the thermodynamic point of view, osmolyte raises mid-point of thermal denaturation (Tm) of proteins while having no significant effect on ΔGD° (free energy change at physiological condition). Unfavorable interaction with the peptide backbone due to preferential hydration is the major driving force for folding of unfolded polypeptide in presence of osmolyte. However, the thermodynamic basis of stress protection and origin of compatibility Paradigm has been a debatable issue. In the present manuscript, we attempt to elaborate the origin of stress protection and compatibility Paradigm of osmolytes based on the effect on thermodynamic stability of proteins. We also infer that protective effects of osmolytes on ΔGD° (of proteins) could also indicate its potential involvement in unfolded protein response and overall stress biology on macromolecular level.

A framework for the deployment of adaptable web service compositions
Service Oriented Computing and Applications, 2007Co-Authors: Luciano Baresi, Elisabetta Di Nitto, Carlo Ghezzi, Sam GuineaAbstract:The Basic Paradigm of service-oriented architectures—publication, discovery, and use—can be interpreted in different ways. Current technologies assume a static and rigid approach: UDDI was conceived with the idea of a centralized repository for service publication and BPEL only supports design–time bindings between the orchestrated workflow and the external services. The trend, however, is towards more flexibility and dynamism. The single centralized repository is being substituted by dedicated repositories that cooperate and exchange information about stored services on demand. Design–time compositions are complemented by mechanisms to allow for the selection and binding of services at runtime.

Anomalous Cosmic Rays: Messengers from the Outer Heliosphere
Space Science Reviews, 2001Co-Authors: Horst FichtnerAbstract:In this review much of the current knowledge about the physics of anomalous cosmic rays is surveyed. These energetic particles are, most probably, accelerated at the so-called heliospheric shock which terminates the supersonic solar wind expansion. After a presentation of the general scenario embracing a description of the heliosphere, the Basic Paradigm explaining the existence of anomalous cosmic rays and the relevant observations, the main problems connected to the physics of this particular cosmic-ray component are identified and discussed in detail. To this end, the characteristics of the progenitor as well as descendant particle populations, i.e. interstellar neutral atoms, pick-up ions, and energetic neutral atoms, and those of galactic cosmic rays are described from an observational as well as a theoretical perspective, as far as they are related to heliospheric research. The relevance of heliospheric physics is pointed out as a vital link between Basic (plasma) physics and (extra-heliospheric) astrophysics as well as a test bed for astrophysical concepts.
