Chaotic response of global climate to long-term solar forcing variability

open access: yes, 2009
It is shown that global climate exhibits chaotic response to solar forcing variability in a vast range of timescales: from annual to multi-millennium. Unlike linear systems, where periodic forcing leads to periodic response, nonlinear chaotic response to

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

An Inverse Approach for Finding Graphs with a Failed Zero Forcing Number of k

open access: yesMathematics, 2023
For a given a graph G, the zero forcing number of G, Z(G), is the smallest cardinality of any set S of vertices on which repeated applications of the forcing rule results in all vertices being included in S.

The Density Probability Distribution in Compressible Isothermal Turbulence: Solenoidal versus Compressive Forcing

open access: yes, 2008
The probability density function (PDF) of the gas density in turbulent supersonic flows is investigated with high-resolution numerical simulations. In a systematic study, we compare the density statistics of compressible turbulence driven by the usually ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Forcing Pulsations by Means of a Siren for Gas Turbine Applications

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2020
A siren is a robust fast-valve that generates effective flow pulsations and powerful noise levels under well-controlled conditions. It operates under the inlet flow conditions of a gas turbine combustor.

Di-Forcing Polynomials for Cyclic Ladder Graphs CLn

open access: yesMathematics, 2023
The cyclic ladder graph CLn is the Cartesian product of cycles Cn and paths P2, that is CLn=Cn×P2, (n≥3). The di-forcing polynomial of CLn is a binary enumerative polynomial of all perfect matching forcing and anti-forcing numbers.

Frequency locking of modulated waves

open access: yes, 2010
We consider the behavior of a modulated wave solution to an $\mathbb{S}^1$-equivariant autonomous system of differential equations under an external forcing of modulated wave type.

Forced Sterilization

open access: yesVoices in Bioethics, 2022
Photo by Renè Müller on Unsplash INTRODUCTION Forced sterilization of women around the globe is a human rights violation and bioethical concern. In the past, countries enacted laws to forcibly sterilize women deemed unfit to procreate. Although many of these laws have been retracted, the practice persists under the guise of public health. More recently,

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
