Optimal significance tests in simultaneous equation models [PDF]
Consider testing the null hypothesis that a single structural equation has specified coefficients. The alternative hypothesis is that the relevant part of the reduced form matrix has proper rank, that is, that the equation is identified. The usual linear

This paper provides a principled account of why dimensionless invariants must arise in any admissible representation of a closure-first relational ontology. In the Coherence-Relational Blockworld (cRBW) framework, reality is identified with a single globally admissible relational structure, while representations introduce arbitrary descriptive elements

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Indexing images of buildings based on geometrical invariant Hough descriptors [PDF]
, 2012 A CBIR system for retrieving images with specific buildings from databases is proposed in this paper. We exploit the parallelism invariance property of the line features of buildings in images in the derivation of two new geometrically invariant linear ...

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control
FEBS Open Bio, EarlyView.Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.
