Yoga as an integrative approach for prevention and treatment of oral cancer

International Journal of Yoga, 2018
Despite tremendous advancements in medicine, the number of oral cancer cases continues to increase, and the need for integrating alternate medicine or adopting an integrative approach has become a compelling cost-effective requirement for the management ...

Neural proximity, vascular remodeling, and perineural immune exclusion across the cervical neoplasia spectrum – a whole-slide, nerve-anchored spatial analysis of 135 cases

Polish Journal of Pathology
Cervical carcinogenesis unfolds within a complex tissue ecosystem. While epithelial biomarkers and HPV status inform risk, the contribution of local neural circuits and their relationship to angiogenesis and cytotoxic immunity remains insufficiently ...

Integration host factor is required for the DNA inversion that controls phase variation in Escherichia coli. [PDF]

Proceedings of the National Academy of Sciences, 1987
The on-and-off expression (phase variation) of type 1 fimbriae, encoded by fimA, in Escherichia coli is controlled by the inversion of a promoter-containing 314-base-pair DNA element. This element is flanked on each side by a 9-base-pair inverted, repeat sequence and requires closely linked genes for inversion.

Resolving soft X-ray photons with a high-rate hybrid pixel detector

Frontiers in Physics
Due to their high frame rates and dynamic range, large area coverage, and high signal-to-noise ratio, hybrid silicon pixel detectors are an established standard for photon science applications at X-ray energies between 2 keV and 20 keV.

Analysis of Factors Affecting Optical Performance of GaN-Based Micro-LEDs with Quantum Dots Films

Crystals, 2020
Optical performance in terms of light efficiency, color crosstalk and ambient contrast ratio were analyzed for blue GaN-based micro-light emitting diodes (micro-LEDs) combined with red/green quantum dots (QDs)-polymethyl methacrylate (PMMA) films.

Poisson inverse problems [PDF]

, 2006
In this paper we focus on nonparametric estimators in inverse problems for Poisson processes involving the use of wavelet decompositions. Adopting an adaptive wavelet Galerkin discretization, we find that our method combines the well-known theoretical ...

Cyclicity of a simple focus via the vanishing multiplicity of inverse integrating factors

Journal of Differential Equations, 2013
First we provide new properties about the vanishing multiplicity of the inverse integrating factor of a planar analytic differential system at a focus. After we use this vanishing multiplicity for studying the cyclicity of some simple foci of several classes of planar analytic differential systems.

The inverse integrating factor for some classes of n-th order autonomous differential systems

Journal of Mathematical Analysis and Applications, 2015
Consider an \(n\)-order autonomous differential system \[ \dot{x}=p(x), \eqno{(1)} \] where \(x=(x_1,x_2,\ldots,x_n) \in D \subseteq \mathbb{R}^n\) and \(p(x)=(p_1(x),p_2(x),\ldots,p_n(x))\), with \(p_i\in C^1(D, \mathbb R)\) functions in \(D\). The vector field associated to system (1) is denoted by \[ \mathcal{X}= \sum_{i=1}^n p_i(x) \frac{\partial}{\
