Transparent and heat-insulation bionic hydrogel-based smart window system for long-term cooling and waste heat collection
With the energy crisis and climate warming, the position of a new generation of smart windows is becoming increasingly important, and materials or systems that can have high blocking of near-infrared (NIR) and ultraviolet (UV) and high transmittance of visible light (VIS) are needed. Currently, it is difficult for smart heat-insulation materials to achieve high transmittance of VIS, good UV isolation, outstanding cooling and thermal insulation, and excellent waste heat collection. Here, we desi…

The Lyman-alpha and Continuum Origins Survey II: the connection between the escape of ionizing radiation and Lyman-alpha halos in star-forming galaxies
One of the current challenges in galaxy evolution studies is to establish the mechanisms that govern the escape of ionizing radiation from galaxies. In this work, we investigate the connection between Lyman Continuum (LyC) escape and the conditions of the Circumgalactic Medium (CGM), as probed by Ly$α$ halos (LAHs) in emission. We use Ly$α$ and UV continuum imaging data from the Lyman alpha and Continuum Origins Survey (LaCOS), targeting 42 nearby ($z \simeq 0.3$), star-forming galaxies with …

ExoPhoto: A Database of Temperature-Dependent Photodissociation Cross Sections
We present the ExoPhoto database (https://exomol.com/exophoto/), an extension of the ExoMol database, specifically developed to address the growing need for high-accuracy, temperature-dependent photodissociation cross section data towards short-UV wavelengths. ExoPhoto combines theoretical models from three major computational databases (ExoMol, UGAMOP and PhoMol) and experimental datasets from two experimental groups, providing extensive wavelength and temperature coverage. ExoPhoto currently …

Performance and radiation damage mitigation strategy for silicon photomultipliers on LEO space missions
Space missions require lightweight, low-power consuming, radiation-tolerant components. Silicon photomultipliers are increasingly used for detecting near-UV, optical, and infrared light in space due to their compact design, low cost, low power consumption, robustness, and high photo-detection efficiency, which makes them sensitive to single photons. Although SiPMs outperform traditional photomultiplier tubes in many areas, concerns about their radiation tolerance and noise remain. In this study…

Investigation of Martian UV Dayglow Emissions in the Southern Hemisphere during Solar Quiet-time Conditions: Insights from Multi-year MAVEN/IUVS Observations
The southern hemisphere of Mars possesses concentrated region of strong crustal magnetic fields (CMF), which generate localized magnetic anomalies that can influence atmospheric dynamics and energy deposition in the Martian thermospheric-ionospheric system. Although their effects on the atmosphere (>200 km) in the southern hemisphere are well documented, however their role in modulating the behavior of atmospheric plasma and neutrals below 200 km are poorly understood. The atmosphere at these a…

Unraveled origin of the multi-directional and super wide optical-response found on metal/n-Si

Unraveled origin of the multi-directional and super wide optical-response found on metal/n-Si
The optical responses for UV to NIR and muti-directional photo current have been found on Au (metal) on n-Si device. The unique phenomena have been unresolved since the first sample fabricated in 2007. The self organized sub-micron metal with various crystal faces was supposed to activate as an optical wave guide into Si surface. This, however, is insufficient to explain the unique features above. Thus, for more deep analysis, returning to consider the Si-band structure, indirect/direct transit…

Biden's record on covid
Saw a comment along the lines of: "seems unfair to criticise Biden's record on covid, while the situation now under Trump is so much worse".
But I don't think of them as separate. Biden's government _contributed_ to how covid stands under Trump.
If Biden's lot had taken the opportunity to educate people (at least the ones open to considering science findings) that
- it's airborne like smoke
- an empty room can hold infectious virus
- air filters, UV and fresh air reduce the levels of it
- masks work better the better they fit
- you can be infectious without/before symptoms
- you're fairly likely still to be infectious for 10 days, a few people longer
- current vaccines don't stop you catching it or transmitting it
- it can mess with your immune system so you're more likely to catch other things
- vaccinated people can still get Long Covid
- it's not "mild", it's just that the damage is quiet
then even if they hadn't done anything more to address the problem, people would be in a far better position to deploy their own common sense.
And unlike funding or laws, that investment in _knowledge_ is something it would be difficult for Trump's lot to roll back.
But Biden & co chose instead to play down the risks, and explicitly or implicitly mislead people (e.g. the 5-day quarantine, which contradicts the real infectious period).
So, yes it's worse now, but they _contributed_ to how it is now. They chose to encourage misapprehensions and confusion, and the effects of that choice are still playing out now.
Not letting them off the hook on the grounds of being comparatively "less bad", when they themselves laid some of the foundations of the current state of play.
