Is Solar Minimum 24/25 Another Unusual One?
نویسندگان
چکیده
The solar minimum 23/24 is considered to be unusual because it exhibits features that differ notably from those commonly seen in pervious minima. In this letter, we analyze the polar magnetic field, potential-field solution of corona, and in-situ wind measurements see whether recent 24/25 another one. While dipolar configuration are during 22/23 earlier minima persist for about half a year after absolute cycle 24, corona has morphology more complex than simple dipole before minimum. fast streams less dominant 23/24. IMF strength, density mass flux historically low regained 24/25, but still do not reach level. From analysis Letter, seems only partially unusual, recovery may result enhancement field.

the term ‘Cartesian’ has suffered the same fate in certain circles (see below, n.3). 2 John Foster offers a discussion of a priori objections to dualistic psychophysical causation in Foster [1991], pp 158–185. He goes on (pp 185–201) to discuss causal closure and causal overdetermination as if they constituted empirical objections; as I argue below, I disagree with his categorisation, while acc...

One ROCK is not like another he mammalian rho kinases, ROCKI and ROCKII, control distinct cytoskeletal functions from distinct locations, report Yoneda et al. on page 443. ROCKI is required for formation of actin stress fibers and cell adhesion, whereas ROCKII is needed for phagocytosis. The ROCK proteins are major effectors of the Rho signaling pathway, controlling cell adhesion, motility, and...

Highly aligned Cu2O, Cu2O/CuO, Cu2O/CuO/TiO2 and Cu2O/TiO2 nanowires arrays on Au substrates were prepared by controlled air annealing of the electrodeposited Cu nanowires and furthered with dip coating. Photoelectrochemical investigations were carried out to determine their potential as photocathodes for water photo-reduction. The photocurrent of the Cu2O nanowires photocathode was found to be...

We investigate the complexity of an optimization problem in Boolean propositional logic related to information theory: Given a conjunctive formula over a set of relations, find a satisfying assignment with minimal Hamming distance to a given assignment that satisfies the formula (NearestOtherSolution, NOSol). We present a complete classification with respect to the relations admitted in the for...
متن کاملGenetically engineered phytoremediation: one man's trash is another man's transgene.
Plant-based environmental remediation, or phytoremediation, has been widely pursued in recent years as a favorable clean-up technology and is an area of intensive scientific investigation. For the vast majority of field applications, vegetative 'phyto-crops' are selected specifically for their capacity for site decontamination and not for additional concurrent or post-remediation utility. By co...
