During the sudden stratospheric warming (SSW) event in 2013, we investigated American low latitude around 75°W. We used 12 Global Positioning System (GPS) receivers, a pair of magnetometers, and NASA Thermosphere Ionosphere Mesosphere Energetics Dynamics (TIMED) satellite airglow instrument to unveil total electron content (TEC), inferred vertical drift, changes neutral composition, respectivel...

‎ In the present article‎, ‎we study some categorical properties of the category {$bf‎ Cpo_{Sep}$-$S$} of all {separately strict $S$-cpo's}; cpo's equipped with‎ a compatible right action of a separately strict cpo-monoid $S$ which is‎ strict continuous in each component‎. ‎In particular‎, we show that this category is reflective and coreflective in the‎ category of $S$-cpo's‎, ‎find the free a...

Abstract We discovered a new growth mode of dust grains to kilometer-size bodies in protoplanetary disks that evolve via viscous accretion and magnetically driven disk winds (MDWs). solved an approximate coagulation equation with time-evolving consist both gas solid components using one-dimensional model. With grain growth, all particles initially drift inward toward the central star due drag f...

This paper introduces the logics of super-strict implications, where a implication is strengthening C.I. Lewis' strict that avoids not only paradoxes material but also those implication. The semantics implications obtained by (normal) relational for We consider all are based on frames modal in cube. it shown connexive they validate Aristotle's Theses and (weak) Boethius's Theses. A proof-theore...

A problem of performance enhancement for multiple frequencies estimation is studied. First, we consider a basic gradientbased estimation approach with global exponential convergence. Next, we apply dynamic regressor extension and mixing technique to improve transient performance of the basic approach and ensure non-strict monotonicity of estimation errors. Simulation results illustrate benefits...
