On root frames in $${\mathbb {R}}^d$$
Sampling Theory, Signal Processing, and Data Analysis, 2023 \emph{A root frame} for $\mathbb{R}^d$ is a finite frame whose vectors form a root system. In this note we establish some elementary properties of this class of frames and prove that root frames constitute a subclass of scalable frames. In addition, we show that root frames are examples of a larger class of frames called \emph{eigenframes}.

New results on R(D) and R(D*) from Belle [PDF]
Proceedings of The 39th International Conference on High Energy Physics — PoS(ICHEP2018), 2019 Indications of lepton flavor universality violation in the decays \(B \to D^{(*)}\tau\nu\) have triggered substantial interest and could be a hint for new physics. Useful observables to probe new physics in these decays are the ratios of the branching fractions, \(R(D^{(*)}) \equiv \mathcal{B}(\bar{B} \to D^{(*)}\tau\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}

Geometric complexity of embeddings in $${\mathbb{R}^{d}}$$ R d [PDF]
Geometric and Functional Analysis, 2014 v2: an upper bound is established on refinement complexity for simplicial n-complexes in R^{2n}. Exponential lower bound is extended to a wider range of dimensions.

Complementary NAD+ replacement strategies fail to functionally protect dystrophin-deficient muscle
Skeletal Muscle, 2020 Background Duchenne muscular dystrophy (DMD) is a progressive muscle wasting disorder stemming from a loss of functional dystrophin. Current therapeutic options for DMD are limited, as small molecule modalities remain largely unable to decrease the ...

A note on duplication of R&D and R&D subsidies [PDF]
Economics Bulletin, 2004 We show that the presumed incompatibility of uncoordinated R&D and competition is not fundamental, but hinges on the nature of R&D spillovers. As a consequence, R&D subsidies may be more effective than previously thought.

Metabolism-driven in vitro/in vivo disconnect of an oral ERɑ VHL-PROTAC
Communications BiologyTargeting the estrogen receptor alpha (ERα) pathway is validated in the clinic as an effective means to treat ER+ breast cancers. Here we present the development of a VHL-targeting and orally bioavailable proteolysis-targeting chimera (PROTAC) degrader ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
