is also that of all functions of the form (1 + x2)-2N-c+lQ(x) where Q is a polynomial of degree 4N 2 or lower, the conditions determining the above formula for any a and N are the same as those determining Harper's formula for (using "k" and "n" in the meaning given them in [1]) k = a + 2N -2, n = 2N.

Thermostable neutral metalloprotease from Geobacillus sp. EA1 does not share thermolysin's preference for substrates with leucine at the P1′ position

open access: yesFEBS Letters, EarlyView.
Knowing how proteases recognise preferred substrates facilitates matching proteases to applications. The S1′ pocket of protease EA1 directs cleavage to the N‐terminal side of hydrophobic residues, particularly leucine. The S1′ pocket of thermolysin differs from EA's at only one position (leucine in place of phenylalanine), which decreases cleavage ...

Discrete generalized functions

open access: yesJournal of Mathematical Analysis and Applications, 1972
A mapping from the Gaussian integers into the complex numbers is called a discrete function. Duffin [I] has studied properties of discrete functions. In his study, Duffin makes use of certain types of operators which we will call Duffin operators. More precisely, an operator F mapping the collection il of all discrete functions into itself is a Duffin ...

On generating functions of Hausdorff moment sequences [PDF]

open access: yes, 2014
The class of generating functions for completely monotone sequences (moments of finite positive measures on $[0,1]$) has an elegant characterization as the class of Pick functions analytic and positive on $(-\infty,1)$. We establish this and another such

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Some remarks regarding the $(p,q)-$Fibonacci and Lucas octonion polynomials

open access: yesUniversal Journal of Mathematics and Applications, 2018
We investigate the $(p,q)-$Fibonacci and Lucas octonion polynomials. The main purpose of this paper is using of some properties of the $(p,q)-$ Fibonacci and Lucas polynomials. Also for present some results involving these octonion polynomials, we obtain

A Note on Bi-Orthogonal Polynomials and Functions

open access: yesFluids, 2020
The theory of orthogonal polynomials is well established and detailed, covering a wide field of interesting results, as, in particular, for solving certain differential equations.

On positive generalized functionals

open access: yesJournal of Functional Analysis, 1987
Given a Gaussian space (\({\mathcal N}^*,{\mathcal B},d\mu)\), where \({\mathcal N}^*\) is the dual of a real nuclear space \({\mathcal N}\), B its topological \(\sigma\)-algebra and \(d\mu\) a Gaussian measure on \({\mathcal B}\), we construct spaces of test functionals on \({\mathcal N}^*\) as follows.

Theta functions and Hodge numbers of moduli spaces of sheaves on rational surfaces

open access: yes, 1998
Let (S,H) be a rational algebraic surface with an ample divisor. We compute generating functions for the Hodge numbers of the moduli spaces of H-stable rank 2 sheaves on S in terms of certain theta functions for indefinite lattices that were introduced ...

C‐mannosylation promotes ADAMTS1 activation and secretion in human testicular germ cell tumor NEC8 cells

open access: yesFEBS Letters, EarlyView.
C‐mannosylation is a unique form of protein glycosylation. In this study, we demonstrated that ADAMTS1 is C‐mannosylated at Trp562 and Trp565 in human testicular germ cell tumor NEC8 cells. We found that C‐mannosylation of ADAMTS1 is essential for its secretion, processing, enzymatic activity, and ability to promote vasculogenic mimicry. These findings
