Forcing the Wheel

Order, 2023
Abstract Over the past 10 years, there has been considerable interest in exploring questions connecting dimension for posets with graph theoretic properties of their cover graphs and order diagrams, especially with the concepts of planarity and treewidth.

Contributions of Heating and Forcing to the High-Latitude Lower Thermosphere: Dependence on the Interplanetary Magnetic Field [PDF]

Journal of Astronomy and Space Sciences, 2010
To better understand the physical processes that maintain the high-latitude lower thermospheric dynamics, we have identified relative contributions of the momentum forcing and the heating to the high-latitude lower thermospheric winds depending on the ...

Observations of diurnal and spatial variability of radiative forcing by equatorial deep convective clouds [PDF]

, 2004
From geostationary satellite observations of equatorial Africa and the equatorial east Atlantic during May and June 2000 we explore the radiative forcing by deep convective cloud systems in these regions. Deep convective clouds (DCCs) are associated with

Flower bud development of almond cultivars based on three different methods

Folia Horticulturae, 2023
Flower bud development of fruit trees plays a key role in their climatic adaptation. It is closely related to dormancy release that determines winter frost susceptibility. Detailed characterisation of flower bud development of 25 almond (Prunus amygdalus

A Model in Which Well-Orderings of the Reals Appear at a Given Projective Level

Axioms, 2022
The problem of the existence of analytically definable well-orderings at a given level of the projective hierarchy is considered. This problem is important as a part of the general problem of the study of the projective hierarchy in the ongoing ...

Radiative forcing in the 21st century due to ozone changes in the troposphere and the lower stratosphere [PDF]

, 2003
Radiative forcing due to changes in ozone is expected for the 21st century. An assessment on changes in the tropospheric oxidative state through a model intercomparison ("OxComp'') was conducted for the IPCC Third Assessment Report (IPCC-TAR).

Energy budget constraints on historical radiative forcing [PDF]

, 2020
Radiative forcing is a fundamental quantity for understanding anthropogenic and natural drivers of past and future climate change1, yet significant uncertainty remains in our quantification of radiative forcing and its model representation2,3,4.

The Use of Organic Nano-Supplements of Fertilizer for Lily Forcing Period

Advances in Horticultural Science, 2019
Lilium is one of the most important ornamental plants after roses, carnations and chrysanthemum in the world that is requested as potted of cut flowers. It is so important to consider its quality along with its production rate in terms of yield (quantity)

On the Countering of Free Vibrations by Forcing: Part I—Non-Resonant and Resonant Forcing with Phase Shifts

Applied Mechanics, 2022
The question addressed is whether the free oscillations of a continuous system can be suppressed, or at least the total energy reduced, by applying external forces, using as example the linear undamped transverse oscillations of a uniform elastic string.
