Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Tachyonic inflation in loop quantum cosmology
European Physical Journal C: Particles and Fields, 2019 A tachyon field might be responsible for cosmological inflation at an early time and contribute to cosmological dark matter at a later time. We investigate tachyonic inflation by analyzing a tachyon field with different potentials in the framework of ...

Universal features of quantum bounce in loop quantum cosmology
Physics Letters B, 2017 In this Letter, we study analytically the evolutions of the flat Friedmann–Lemaitre–Robertson–Walker (FLRW) universe and its linear perturbations in the framework of the dressed metric approach in loop quantum cosmology (LQC). Assuming that the evolution

Alignment of the Starlings: Learning With Generative AI
Future Humanities, Volume 4, Issue 1, May 2026.ABSTRACT I will argue that answers to normative questions concerning the place of generative AI in learning rest on answers to ontological questions regarding (1) precisely what is happening when a human ‘interacts’ with generative AI and (2) What is distinctive about organic learning as opposed to currently existing ‘machine learning’ (3) What is the ...

Advanced Intelligent Systems, Volume 8, Issue 1, January 2026.This perspective article considers what computations optical computing can and should enable. Focusing upon free‐space optical computing, it argues that a codesign approach whereby materials, devices, architectures, and algorithms are simultaneously optimized is needed.

Data‐Driven Review on Aerogels and Polymeric Aerogels
Angewandte Chemie, Volume 137, Issue 28, July 7, 2025.A review goes to data‐driven. An exhaustive literature survey provides an overview of research status on aerogels, a category of highly porous solids with unique physicochemical properties. Statistical/data‐driven analysis tells us positive/negative aspects; aerogels have a promising potential to contribute to emerging energy/environmental issues ...

Annalen der Physik, Volume 538, Issue 1, January 2026.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Loop quantum cosmology: II. Volume operators [PDF]
Classical and Quantum Gravity, 2000 Volume operators measuring the total volume of space in a loop quantum theory of cosmological models are constructed. In the case of models with rotational symmetry an investigation of the Higgs constraint imposed on the reduced connection variables is necessary, a complete solution of which is given for isotropic models; in this case the volume ...
