The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, EarlyView.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Searching for Rotational X‐Ray Modulation on TIC 277539431
Astronomische Nachrichten, EarlyView.ABSTRACT TIC 277539431, a fast rotating M7 dwarf, was detected to host the highest latitude flare to date at 81°$$ {81}^{{}^{\circ}} $$. Magnetic activity like stellar flares occurring at high latitude indicate occurrence of coronal loops at these latitudes on fully‐convective M dwarfs. In contrast, sunspots usually occur below 30°$$ {30}^{{}^{\circ}} $

Focused laser Doppler velocimeter [PDF]
, 1976 A system for remotely measuring velocities present in discrete volumes of air is described. A CO2 laser beam is focused by a telescope at such a volume, a focal volume, and within the focusable range, near field, of the telescope.

Listening to Hong Kong children's perspectives through pretend play
British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) has become an increasing concern in recent years. The issue has been regularly discussed by different stakeholders. However, the rising concern regarding quality in ECEC has not seriously taken into account children's perspectives.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT We describe the “skipping rope technique” for managing burr entrapment during rotational atherectomy. Sequential counterclockwise rotational force is applied to the drive shaft, generating alternative torque dynamics. This maneuver provides a safe method to disengage a stuck rotaburr, offering operators an additional strategy for this ...

Carbon Energy, EarlyView.Transition metal (TM) ions with empty eg orbitals induce single‐electron delocalization in Ni3+ to form the resonance structure of Ni─OO─TM through the high‐entropy effect. High‐nickel cathode materials with electron resonance structure have the advantages of improving thermodynamic stability, suppressing phase transitions, and mitigating lattice ...
