ATMOSFEAR: Horror of nature and the nature of horror in Algernon Blackwood

open access: yesOrbis Litterarum, EarlyView.
Abstract The impact that the stories of Algernon Blackwood (1869–1951) have had on the literature of the uncanny can hardly be overestimated. However, there is almost no research on Blackwood's life and work. Against the background of a presentation of themes and motifs of Blackwood's narrative œuvre, this article develops a characteristic of his ...

QUASAT: An orbiting very long baseline interferometer program using large space antenna systems [PDF]

open access: yes, 1985
QUASAT, which stands for QUASAR SATELLITE, is the name given to a new mission being studied by NASA. The QUASAT mission concept involves a free flying Earth orbiting large radio telescope, which will observe astronomical radio sources simultaneously with

Debiasing piecewise deterministic Markov process samplers using couplings

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract Monte Carlo methods—such as Markov chain Monte Carlo (MCMC) and piecewise deterministic Markov process (PDMP) samplers—provide asymptotically exact estimators of expectations under a target distribution. There is growing interest in alternatives to this asymptotic regime, in particular in constructing estimators that are exact in the limit of ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental 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 ...

Negative Thermal Expansion in Metastable PbVO3: High‐Pressure Synthesis, Advances, and Perspectives

open access: yescMat, Volume 2, Issue 4, December 2025.
ABSTRACT Most materials expand on heating; however, some materials show the opposite trend, in which the overall volume contracts upon heating, a phenomenon known as negative thermal expansion (NTE). Materials exhibiting NTE are highly valued for their unique ability to tailor thermal expansion, especially in achieving zero thermal expansion when ...

Direct Data‐Driven State‐Feedback Control of Linear Parameter‐Varying Systems

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 35, Issue 16, Page 6955-6977, 10 November 2025.
ABSTRACT The framework of linear parameter‐varying (LPV) systems has shown to be a powerful tool for the design of controllers for complex nonlinear systems using linear tools. In this work, we derive novel methods that allow us to synthesize LPV state‐feedback controllers directly from only a single sequence of data and guarantee stability and ...

Astronomical observations with the University College London balloon borne telescope [PDF]

open access: yes
The characteristics of a telescope system which was developed for high altitude balloon astronomy are discussed. A drawing of the optical system of the telescope is provided. A sample of the signals recorded during one of the flights is included.
