ANN-based optimized design of doubly reinforced rectangular concrete beams based on multi-objective functions

open access: yesJournal of Asian Architecture and Building Engineering, 2023
In the structural engineering field, multi-objective optimization is a difficult task as demands of objective functions in structural designs are sometimes conflicting, such as costs and structural weight.

UFO – The Universal FeynRules Output [PDF]

open access: yesComputer Physics Communications, 2012
We present a new model format for automatized matrix-element generators, the so- called Universal FeynRules Output (UFO). The format is universal in the sense that it features compatibility with more than one single generator and is designed to be flexible, modular and agnostic of any assumption such as the number of particles or the color and Lorentz ...

Unraveling the Molecular Mechanisms Underlying Spontaneous Multipolar Mitosis Through CIN‐seq

open access: yesAdvanced Science, Volume 13, Issue 40, 17 July 2026.
Multipolar mitosis, a hallmark of chromosomal instability (CIN), drives tumor heterogeneity but is challenging to study in live cells. Using CIN‐seq, a single‐cell multiomics method, we profiled rare CIN events and identified mechanisms associated with viable multipolar mitosis, including PTEN attenuation, Rho GTPase‐driven cytokinesis failure, and ...

Geological Revolutions in the Late 20th and Early 21st Centuries: Plate Tectonics, Extraterrestrial Impacts, and Snowball Earth

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT During the late 20th and early 21st century three conceptual revolutions reordered our understanding of the history of the Earth: The spread of plate tectonic theory from the 1960s onward which brought geology the first meaningful theory for building mountains and the migration of continents; the rebirth of catastrophism in 1980 with the ...

Da Gud blev til en lille grøn mand fra Rummet

open access: yesReligionsvidenskabeligt Tidsskrift, 1992
The International Raëlian Movement, founded by the French journalist Claude Vorlihon (Raël) in 1974, is one of the best consolidated UFO-cults, now present in more than 40 countries.

Stabilized diverse HIV-1 envelope trimers for vaccine design

open access: yesEmerging Microbes and Infections, 2020
One of the major goals in HIV-1 vaccine development is to achieve properly folded and stabilized envelope glycoprotein (Env) trimers that mimic the native Env on the mature virion.

Endophyte‐induced systemic spatial reprogramming of metabolism in Populus trichocarpa roots under drought

open access: yesNew Phytologist, Volume 251, Issue 1, Page 438-454, July 2026.
Summary Beneficial, facultative endophytes help plants thrive in challenging environments by altering their host's metabolism, but how these cellular scale metabolic changes propagate to the systems biology scale is unknown. In this work, we employed a high‐resolution chemical imaging approach to map metabolic changes at the Populus trichocarpa root ...

Sociale medier som læringsredskaber

open access: yesDansk Universitetspaedagogisk Tidsskrift, 2011
Kan sociale medier anvendes som læringsredskaber til støtte for sociale, kollaborative processer, der er udfordrende og motiverende, og som samtidig understøtter (fremmedsprogs)tilegnelsen?Artiklen diskuterer eksempler på fagdidaktiske udfordringer i ...

From image-based detection to parameter-based prediction of UFO events in KSTAR

open access: yesNuclear Fusion
Plasma disruption prediction is a central challenge for reliable tokamak operation, yet the predictive value of intermediate off-normal phenomena, particularly UFO (unidentified flying object) events that may precede or trigger disruptions, remains ...

A method for detecting the presence of organic fraction in nucleation mode sized particles [PDF]

open access: yesAtmospheric Chemistry and Physics, 2005
New particle formation and growth has a very important role in many climate processes. However, the overall knowlegde of the chemical composition of atmospheric nucleation mode (particle diameter ...
