Virtual 3D tumor marking-exact intraoperative coordinate mapping improve post-operative radiotherapy
Radiation Oncology, 2011 The quality of the interdisciplinary interface in oncological treatment between surgery, pathology and radiotherapy is mainly dependent on reliable anatomical three-dimensional (3D) allocation of specimen and their context sensitive interpretation which ...

Delay-Coordinate Maps and the Spectra of Koopman Operators [PDF]
Journal of Statistical Physics, 2019 The Koopman operator induced by a dynamical system is inherently linear and provides an alternate method of studying many properties of the system, including attractor reconstruction and forecasting. Koopman eigenfunctions represent the non-mixing component of the dynamics. They factor the dynamics, which can be chaotic, into quasiperiodic rotations on

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Numerical conformal mapping onto a rectangle with applications to the solution of Laplacian problems
, 1988 Let F be the function which maps conformally a simple-connected domain onto a rectangle R, so that four specified points on are mapped Ω∂respectively onto the four vertices of R. In this paper we consider the problem of approximating the conformal map F,

Multicentric tracking of multiple agents by anterior cingulate cortex during pursuit and evasion
Nature Communications, 2021 Pursuit or evasion requires world-centric and agent-centric representation to coordinate navigation and motor control. The dorsal anterior cingulate cortex, which communicates bi-directionally with both the hippocampal complex and premotor areas serve a ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Time-delay coordinates and polynomial mappings
Advances in Mathematics, 2003 A simple model of a dynamical system is a diffeomorphism \(f: M \to M\) of a compact finite-dimensional manifold \(M\) as its state space. Consider the sequence of scalers \[ g(x), g(f(x)), g(f^2(x)),\dots, g(f^n(x)), \dots \] where \(g : M \to \mathbb R^1 \in C^\infty\), \(x \in M\) initial state and \(f^n\) represents the \(n\)-fold composition of ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
