Surfaces in E3 invariant under a one parameter group of isometries of E3
Anais da Academia Brasileira de Ciências, 2000 We develop a convenient surface theory in E³ in order to apply it to the class of the surfaces invariant under a one-parameter group of isometries of E³.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Design of Differential Loudspeaker Line Array for Steerable Frequency-Invariant Beamforming
SensorsDifferential beamforming has attracted much research since it can utilize an array with a small aperture size to form frequency-invariant beampatterns and achieve high directional gains.

Admissibility of Invariant Tests for Means with Covariates [PDF]
Mathematical Methods of Statistics, 2019 For a multinormal distribution with a $p$-dimensional mean vector ${\mbtheta}$ and an arbitrary unknown dispersion matrix ${\mbSigma}$, Rao ([9], [10]) proposed two tests for the problem of testing $ H_{0}:{\mbtheta}_{1} = {\bf 0}, {\mbtheta}_{2} = {\bf 0}, {\mbSigma}~ \hbox{unspecified},~\hbox{versus}~H_{1}:{\mbtheta}_{1} \ne {\bf 0}, {\mbtheta}_{2} ={

On the invariant mean velocity profile for compressible turbulent boundary layers
, 2017 An invariant mean velocity profile is derived and validated by direct numerical simulations of compressible turbulent boundary layers (CTBL) for a range of Reynolds number, Mach number and wall temperature.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer
Molecular Oncology, EarlyView.Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Willmore-Like Tori in Killing Submersions
Advances in Mathematical Physics, 2018 The first variation formula and Euler-Lagrange equations for Willmore-like surfaces in Riemannian 3-spaces with potential are computed and, then, applied to the study of invariant Willmore-like tori with invariant potential in the total space of a ...

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Invariant surfaces with constant mean curvature in H2 x R
, 2008 We classify the profile curves of all surfaces with constant mean curvature in the product space H2 x R, which are invariant under the action of a 1-parameter subgroup of isometries.
