The daily dynamic potential accessibility by car in London on Wednesdays
Journal of Maps, 2017 The map presented in this paper shows the effect of congestion on daily accessibility in the London metropolitan area on Wednesdays. Because of its dynamic nature, it is challenging to both calculate the effects of this phenomenon and to represent it ...

, 1988 This paper attempts to reconcile the various abstract notions of “category of partial maps” which appear in the literature. First a particular algebraic theory (p-categories) is introduced and a representation theorem proved.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Studying Cartographic Game Maps: Video Game Maps Matter.
Interaction Design and Architecture(s)Maps are critical elements of video games that provide an alternative representation of the game world. While navigation is considered an essential function of game maps, they play additional selective roles in and have multiple functions that ...

Elementary examples of essential phantom mappings
Rad Hrvatske akademije znanosti i umjetnosti. Matematičke znanosti, 2015 It is known that essential phantom mappings (of the second kind) between connected CW-complexes do exist. However, it appears that in the literature there are few explicit examples of such mappings. One usually finds descriptions of the domain and the codomain and an existence proof that the set of homotopy classes of mappings from the domain to the ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Inactivation of the Neurospora crassa Gene Encoding the Mitochondrial Protein Import Receptor MOM19 by the Technique of ''Sheltered RIP'' [PDF]
, 1994 We have used a technique referred to as ``sheltered RIP'' (repeat induced point mutation) to create mutants of the mom-19 gene of Neurospora crassa, which encodes an import receptor for nuclear encoded mitochondrial precursor proteins.

Maps on essentially infinite idempotent operators
Journal of Mathematical Analysis and Applications, 2012 Let \(X\) be an infinite-dimensional real or complex Banach space, and \({\mathcal I}(X)\) be the set of all idempotents in the algebra \(B(X)\) of all bounded linear operators on \(X\). In [Stud. Math. 169, No. 1, 21--44 (2005; Zbl 1088.47030)], \textit{P.
