Maser is an acronym for microwave amplification by stimulated emission of radiation; in astronomy mega-masers are masers in galaxies that are ≥ 10(6) times more luminous than typical galactic maser sources. Observational studies of mega-masers can help us to understand their origins and characteristics. More importantly, mega-masers can be used as diagnostic tracers to probe the physical proper...

We designed a protein ladder (hereafter referred to as "Mega-tag") that contains 14 of the most commonly used epitope tags fused to molecular weight markers. The Mega-tag ladder can be simultaneously visualized when anti-tag antibodies are used to detect epitope-tagged recombinant proteins in Western blots. The logarithm of molecular weights and relative mobility of the Mega-tag protein ladder ...

PURPOSE The most common γ-aminobutyric-acid (GABA) editing approach, MEGA-PRESS, uses J-editing to measure GABA distinct from larger overlapping metabolites, but suffers contamination from coedited macromolecules (MMs) comprising 40 to 60% of the observed signal. MEGA-SPECIAL is an alternative method with better MM suppression, but is not widely used primarily because of its relatively poor spa...

Classical automated theorem proving of today is based on ingenious search techniques to find a proof for a given theorem in very large search spaces—often in the range of several billion clauses. But in spite of many successful attempts to prove even open mathematical problems automatically, their use in everyday mathematical practice is still limited. The shift from search based methods to mor...

In this study, a minimal submaximal element of LIT(X) (the lattice of all intuitionistic topologies for X, ordered by inclusion) is determined. Afterwards, a new contractive property, intuitionistic mega-connectedness, is defined. We show that the submaximality and mega-connectedness are not complementary intuitionistic topological invariants by identifying those members of LIT(X) which are int...

Economic globalization has been accompanied by a growing spatial imprint of freight distribution on the landscape, particularly for intermodal terminals such as ports, airports and railyards, but also for logistical activities, namely distribution centers. Economies that have relied on globalization to promote growth, China been the most eloquent example, have relied extensively on major interm...

The Senate Finance Committee’s hearing on July 28, 2021 -- Building Bipartisan Retirement Legislation: How Can Congress Help? spotlighted “mega-IRAs”: individual retirement accounts with balances of $5 million or more. An analysis by the Joint Committee Taxation in advance 28 found that number taxpayers mega-IRAs now exceeds 28,000. followed a June report nonprofit investigative journalism orga...
