Spontaneous symmetry breaking of (1+1)-dimensional $\phi^4$ theory in light-front field theory (II)

open access: yes, 1993
We discuss spontaneous symmetry breaking of (1+1)-dimensional $\phi^4$ theory in light-front field theory using a Tamm-Dancoff truncation. We show that, even though light-front field theory has a simple vacuum state which is an eigenstate of the full ...

YIPFα1A expression is regulated by multilayered molecular mechanisms

open access: yesFEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Truncation and activation of GSK-3β by calpain I: a molecular mechanism links to tau hyperphosphorylation in Alzheimer's disease

open access: yesScientific Reports, 2015
Abnormal hyperphosphorylation of tau is pivotally involved in the pathogenesis of Alzheimer's disease (AD) and related tauopathies. Glycogen synthase kinase 3β (GSK-3β) is a primary tau kinase that is most implicated in tau pathology in AD.

Quotients of dilworth truncations

open access: yesJournal of Combinatorial Theory, Series B, 1990
Sufficient conditions are given for an elementary quotient of the k-th Dilworth truncation of a matroid M to be the k-th Dilworth truncation of a quotient of M. As special cases, contractions of Dilworth truncations and principal truncations by connected flats of Dilworth truncations are characterised as Dilworth truncations of certain matroids.

The C‐terminal region of KIF26B is indispensable for nephron progenitor condensation and kidney formation in mice

open access: yesFEBS Open Bio, EarlyView.
KIF26B plays an important role in kidney development. We engineered mice lacking the C‐terminal region of KIF26B and found severe kidney defects, including bilateral renal agenesis, similar to full Kif26b knockout mice. The mutation disrupted nephron progenitor condensation and reduced Gdnf‐Wnt11 signaling, showing that the KIF26B C‐terminal region is ...

Inference for shared-frailty survival models with left-truncated data [PDF]

open access: yes
Shared-frailty survival models specify that systematic unobserved determinants of duration outcomes are identical within groups of individuals. We consider random-effects likelihood-based statistical inference if the duration data are subject to left ...

Conceptualizing resistance to the Americanization of finance in advanced economy states: The case of the Canadian-dollar system

open access: yesFinance and Society
This article derives four propositions for conceptualizing resistance to the Americanization of finance in advanced economy states. Resistance entails truncation of market-based financial innovations in line with political profit-sharing arrangements ...

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

open access: yesFEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

On truncations for weakly ergodic inhomogeneous birth and death processes

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2014
We investigate a class of exponentially weakly ergodic inhomogeneous birth and death processes. We consider special transformations of the reduced intensity matrix of the process and obtain uniform (in time) error bounds of truncations. Our approach also

Mincing words: Balancing recovery and deletion in word truncation

open access: yesGlossa, 2018
Brazilian Portuguese exhibits word truncation: e.g., the word cruzeiro ‘cruise’ results in the truncated form cruza, where the vowel -a is added to the truncated stem cruz-. Gonçalves (2011) claims that truncated words preserve the onset of the rightmost
