Best Practices for Scientific Collaboration and Ethical Considerations When Working With Human Remains in Southeast Asia

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The roles and responsibilities we occupy as scientists working directly with human remains are diverse, requiring careful ethical consideration. In Southeast Asian contexts, it has been important for us experts and scholars to be in constant correspondence and collaboration, deriving scientific insights into human health, life histories, and ...

Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

The 2023 Flight of the Faint Intergalactic-medium Redshifted Emission Balloon

open access: yesThe Astrophysical Journal Supplement Series
The second iteration of the Faint Intergalactic-medium Redshifted Emission Balloon (FIREBall-2) is a UV multiobject spectrograph designed to detect emission from the circumgalactic and circumquasar medium at low redshifts ( z < 1).

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.

Autonomous spectrographic system to analyse the main elements of fireballs and meteors

open access: yesEarth, Planets and Space, 2018
We present a meteor observation system based on imaging CCD cameras, wide-field optics and a diffraction grating. This system is composed of two independent spectrographs with different configurations, which allows us to capture images of fireballs and ...

Photo‐responsive carbon dots for pyroptosis‐mediated anti‐tumor application

open access: yesResponsive Materials, EarlyView.
Photo‐responsive CDs generate ROS to induce tumor cell pyroptosis, thereby stimulating antitumor immunity. Abstract Pyroptosis refers to a kind of lytic programmed cell death, characterized by the release of pro‐inflammatory cytokines during the process. Owing to its immune response stimulation ability, pyroptosis has garnered considerable attention in

Investigation of the Gamma-Ray Bursts Prompt Emission Under the Relativistically Expanding Fireball Scenario

open access: yesThe Astrophysical Journal Letters
The spectral properties of a composite thermal emission arising from a relativistic expanding fireball can be remarkably different from the Planck function.

Search and Passage Are Decoupled for Migrating Trout Kelts at Multi‐Exit Dam

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Longitudinal and lateral river connectivity have been drastically reduced over time, with hydropower development as a major driver of fragmentation. While fishways are widely implemented to support upstream migration, downstream passage remains a major challenge.

Deepest ever photographed Geminid with small but non-negligible terminal mass

open access: yesAstronomy & Astrophysics
We report an instrumental observation of the very exceptional Geminid fireball that was observed in the scope of the Czech part of the European Fireball Network (EN) on 13 December, 2012 at 4h12m59.4s UT.
