Robust Copy-move Forgery Detection through Invariant Moment Features [PDF]
, 2016 The proposed scheme uses the invariant features extracted from each block to detect the copy-move forgery detection regions in a digital image. In the proposed scheme, an image is first divided into overlapping blocks.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS 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+.

Physical Review Research, 2022 The intensity and the features of sensory stimuli are encoded in the activity of neurons in the cortex. In the visual and piriform cortices, the stimulus intensity rescales the activity of the population without changing its selectivity for the stimulus ...

Some functions with a unique invariant mean
, 1981 In a large class of groups, we construct a function which has a unique invariant mean, but which is not Riemann-measurable.

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

Determination of means by invariance
Journal of Mathematical Analysis and Applications, 2006 If \(M\) is a mean on \(n\)-tuples, \({\mathbf x}=(x_1, \ldots ,x_n)\), and \(f\) a function of a real variable, then \(M\) is called invariant under \(f\) if \(M(f({\mathbf x}))= f(M({\mathbf x}))\), here \(f({\mathbf x})=(f(x_1),\ldots, f(x_n))\). If a mean is strictly monotonic, smooth and invariant under \(f(x) = x^r\), \(r>0\), and \(g(x) =\lambda

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Journal of Inequalities and Applications, 2018 Recently, Kittaneh and Manasrah (J. Math. Anal. Appl. 361:262–269, 2010) showed a refinement of the arithmetic–geometric mean inequality for the Frobenius norm. In this paper, we shall present a generalization of Kittaneh and Manasrah’s result. Meanwhile,
