MCMC and GLMs for estimating regression parameters: Evidence from non-life Egyptian insurance sector [PDF]
Journal of Humanities and Applied Social Sciences, 2019 Purpose – The purpose of this study is to estimate the linear regression parameters using two alternative techniques. First technique is to apply the generalized linear model (GLM) and the second technique is the Markov Chain Monte Carlo (MCMC) method ...

Advanced Science, EarlyView.A multi‐omics framework combining multitissue genome‐wide association studies, metabolomics, transcriptomics, proteomics, and functional validation uncovers the genetic basis of specialized metabolism in quinoa. The study identifies hundreds of metabolite‐associated loci, prioritizes candidate genes for saponin, betalain, and flavonoid biosynthesis ...

Advanced Science, EarlyView.CA9‐targeted PET imaging could be a noninvasive approach to characterize clear cell renal cell carcinoma and associated tumor biology. PET uptake correlates with tumor CA9 expression and is linked to angiogenic activity, immune remodeling, and metabolic reprogramming.

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws
Advanced Intelligent Discovery, EarlyView.The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Das fehlende Glied der Ferrocenophan‐Chemie: Isolierung eines Carba[1]Ferrocenophans
Angewandte Chemie, EarlyView.Die Synthese und Isolierung eines kristallinen Carba[1]Ferrocenophans wird berichtet. Ein einzelnes Kohlenstoffatom ist das bislang kleinste Verbrückungsmotiv, das in ein Ferrocenophan eingebaut werden konnte. Dies resultiert in einem Diederwinkel der Ebenen der Cyclopentadienylringe von 36.7°, was entsprechend die größte Abwinkelung relativ zu ...

A note on the turning point for the quadratic trend
Croatian Review of Economic, Business and Social Statistics, 2019 The quadratic trend is a statistical model described by the quadratic function. Finding its extremum (also called the vertex or the turning point) using differential calculus or completing the square method is very well known in the literature.

Unraveling G‐Quadruplex and i‐Motif Coexistence Within a Double‐Stranded DNA
Angewandte Chemie, EarlyView.The relative thermodynamic profiles of G‐quadruplex (G4), i‐Motif (iM), and the duplex counterpart tune the simultaneous G4 and iM formation within a double‐stranded (ds) DNA. ABSTRACT DNA can transiently fold into variable arrangements, which are expected to exploit regulatory functions. Guanine‐rich sequences can fold into G‐quadruplexes (G4s), while

An explorative study of tourism time series: Evidence from Slovenia and Croatia
Croatian Review of Economic, Business and Social Statistics, 2019 This paper investigates the long-term cointegration between tourism prices and domestic inflation in Croatia and Slovenia. Those two countries share a common economic history and statistical crispness in the 20th century, the time when Econometrics was ...

The Missing Link in Ferrocenophane Chemistry: Isolation of a Carba[1]Ferrocenophane
Angewandte Chemie International Edition, EarlyView.The synthesis and isolation of a crystalline carba[1]ferrocenophane is reported. A single carbon atom is the smallest bridging motif yet incorporated into a ferrocenophane, resulting in a dihedral angle between the cyclopentadienyl ring planes of 36.7°, which is the highest angular deflection from ferrocene's coplanarity observed so far.
