SimE: A Knowledge Graph Embedding Model to Encode Self-Similar Structures Through Algebraic and Geometric Transformations

open access: yesIEEE Access
Knowledge Graphs (KGs), with their intricate hierarchies and semantic relationships, present unique challenges for graph representation learning, necessitating tailored approaches to effectively capture and encode their complex structures into useful ...

Characterizing haploinsufficiency of SHELL gene to improve fruit form prediction in introgressive hybrids of oil palm

open access: yesScientific Reports, 2017
The fundamental trait in selective breeding of oil palm (Eleais guineensis Jacq.) is the shell thickness surrounding the kernel. The monogenic shell thickness is inversely correlated to mesocarp thickness, where the crude palm oil accumulates. Commercial

Development of Nuclear DNA Markers for Applications in Genetic Diversity Study of Oil Palm-Pollinating Weevil Populations

open access: yesInsects, 2023
The oil palm-pollinating weevil (Elaeidobius kamerunicus Faust) was introduced from Cameroon, West Africa, to Malaysia in 1981, and subsequently, to other oil palm-growing countries as well. This study aims to develop a set of robust E.

Mehr als nur ein biochemischer Puffer: Tris als Designer und Regulator einer Metall–Oxo‐Assemblierung

open access: yesAngewandte Chemie, EarlyView.
Tris(hydroxymethyl)aminomethan – schematisch als Oktopus dargestellt – wirkt gleichzeitig als Alkoxy‐Ligand, Chelator und strukturleitender Puffer und programmiert in Wasser die Speziation, die Nukleation und die Heterometall‐Insertion von Polyoxometallaten. ZUSAMMENFASSUNG Polyoxometallate (POMs; molekulare Metall–Oxo‐Cluster) werden typischerweise in

MOFs als neue katalytische Plattform für kovalente adaptive Netzwerke: Katalyse trifft Verstärkung

open access: yesAngewandte Chemie, EarlyView.
Eine neu entwickelte, heterogene, katalytische Plattform für kovalente adaptive Netzwerke (CANs) wird vorgestellt. Dies wird erreicht durch die Immobilisierung von Basen mit geringem Molekulargewicht auf metallorganischen Gerüstverbindungen (MOFs). Der erhaltene Katalysator UiO‐TBD profitiert von der hohen Beladungskapazität von MOFs und demonstriert ...

Pd‐Catalyzed C─C Bond Borylation of Biphenylenes Leading to Tri‐Ortho‐Substituted Biaryls

open access: yesChemistry – A European Journal, EarlyView.
Palladium‐catalyzed ring‐opening C─C borylation of 1‐substituted biphenylenes yields a range of o,o,o′‐trisubstituted biaryls with two ortho‐boryl groups via selective cleavage of the least hindered C─C bond. The resulting diborylated products are readily amenable to sequential, site‐selective postfunctionalization.

Calcium isotopic composition of high-latitude proxy carrier Neogloboquadrina pachyderma (sin.) [PDF]

open access: yes, 2009
The accurate reconstruction of sea surface temperature (SST) history in climate-sensitive regions (e.g. tropical and polar oceans) became a challenging task in palaeoceanographic research.
