Relation between Long-term Activity and Luminosity of the Pre- and Post-novae CT Ser and V446 Her
We show a relation of the pre- and post-nova activity of CT Ser (nova 1948) and V446 Her (nova 1960), known to have remarkably similar orbital periods P _orb . We use both photographic and CCD photometric observations.

The redox‐sensitive transcriptional repressor ZmMS1 coordinates reactive oxygen species homeostasis and lipid allocation for pollen exine and anther cuticle formation. Loss or precocious expression of ZmMS1 causes male sterility. Constitutive overexpression induces dwarfism and semi‐sterility. These findings enable flexible maize male‐sterility systems

Shape of Water: Power Dynamics for Supply Chain Resilience
ABSTRACT The world is facing climate change‐driven disruptions such as extreme weather events, which affect nature as well as firms and their supply chains. Nonetheless, little is known about how supply chain players shape their socioecological resilience, including from a power perspective.

On the Origin of Episodic Accretion in Dwarf Novae
We show that dwarf nova disks in quiescence have rather low magnetic Reynolds number, of order 10^3. Numerical simulations of magnetized accretion disks suggest that under these conditions magnetohydrodynamic turbulence and the associated angular momentum transport is sharply reduced.

A SPOT STRUCTURE OF ACCRETION DISK OF U GEMINORUM
On the basis of modelling of emission lines of dwarf novae U Gem, conclusion is made, that the observed orbital phase change of model parameters of a accretion disk can not be explained in frameworks of Keplerian velocity field in a disk.

Multipoint covalent immobilization of laccase on a modified carbon paper electrode. Robust biointerface with operational stability under chemical, thermal, mechanical, electrical, and storage stress conditions. The practical implementation of enzyme bioelectrodes is limited by the inherent lability of proteins, which require mild conditions to maintain

AbstractWe have summarized the current understanding and recently obtained findings about WZ Sge-type dwarf novae. We also reviewed the historical development of the understanding of these objects, provided the modern criteria, and reviewed the past research in relation to superhumps, early superhumps, and the outburst mechanism. We regard the presence

Characterization of Dwarf Novae Using SDSS Colors [PDF]
We have developed a method for estimating the orbital periods of dwarf novae from the Sloan Digital Sky Survey (SDSS) colors in quiescence using an artificial neural network.

Abstract Scilla s.l. (Asparagaceae: Scilloideae) represents a notable Mediterranean geophyte radiation, yet genus delimitation in subtribe Hyacinthinae has long suffered from inconsistent and conflicting generic concepts. A limited set of informative morphological characters and recurrent shifts in circumscription have repeatedly hindered progress ...

The EUVE Observations of Dwarf Novae [PDF]
In the standard theory of dwarf novae in outburst, the boundary layer region between the inner edge of the accretion disk and the white dwarf surface radiates primarily in the extreme ultraviolet. Using EUVE, observers have been able to obtain spectra with sufficient spectral resolution to characterize accurately the emission from several dwarf novae ...
