Dynamics and Lax-Phillips scattering for generalized Lamb models

, 2006
This paper treats the dynamics and scattering of a model of coupled oscillating systems, a finite dimensional one and a wave field on the half line. The coupling is realized producing the family of selfadjoint extensions of the suitably restricted self ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Oscillations of half-linear second order differential equations

Hiroshima Mathematical Journal, 1995
Let \(\varphi:\mathbb{R}\to\mathbb{R}\) be defined by \(\varphi(s)=|s|^{p-2}s\), with \(p>1\) a fixed number. We extend Sturm's comparison theorem of the linear differential equation \[ {\textstyle {\frac{d}{dt}}} [r(t)u'(t)]+ c(t)u(t)=0 \] to the nonlinear differential equation \[ {\textstyle {\frac{d}{dt}}} \{r(t)\varphi(u'(t))\}+ c(t)\varphi(u(t))=0,

Variational method and conjugacy criteria for half-linear differential equations [PDF]

Archivum Mathematicum, 2013
The authors analyse the conjugacy of the second order half-linear differential equation \[ -[r(t)\Phi (x')]'+c(t)\Phi (x) = 0, \quad \Phi (x) = |x|^{p-1} \operatorname {sgn}\,x, p>1 \] in the interval \([-a,a], a\in \mathbb {R}\) (\(r,c\) being continuous functions and \(r(t)>0\) for \(t \in [-a,a]\)).

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

The unified transform method for linear initial-boundary value problems: a spectral interpretation [PDF]

, 2014
It is known that the unified transform method may be used to solve any well-posed initial-boundary value problem for a linear constant-coefficient evolution equation on the finite interval or the half-line.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Hartman-type comparison theorems for half-linear differential equations of the second order

Electronic Journal of Qualitative Theory of Differential Equations, 2012
Comparison theorem of the Hartman type for a continuous family of nonlinear differential equations of the form $$ \big(p(t, \lambda)\varphi(u')\big)' + q(t,\lambda) \varphi(u) = 0, \lambda \geq 0, \quad \tag{ $\rm E_\lambda$}$$ where $ p \in \mathrm{C ...
