Plant defenses against pathogens are tightly regulated through complex gene expression control mechanisms. The precise activation and repression of defense-related genes are crucial to balancing the trade-off between growth and immunity. Micro RNAs (miRNAs) play a well-established role in the local regulation of…

The optical system is one of the core components for star sensors, whose imaging quality directly influences the performance of star sensors for star detection, thereby determining the attitude control accuracy of spacecrafts. Here, we report a new type of optical system with a catadioptric structure and a large…

Orange (Citrus reticulata Blanco) peel contains a flavonoid glycoside hesperidin (HSD) as the primary component. HSD, upon enzymatic hydrolysis, forms hesperetin (HST) aglycone derivate. These two flavonoids have been predicted to have in-silico affinities for ACE2 and SARS-CoV-2 spike, crucial proteins in SARS-CoV-2…

The Hubble Space Telescope's mission is summarized, with special emphasis placed on the Space Telescope Science Institute's unique experience with Hubble's behavior as an astronomical telescope in the environment of low earth orbit for over two decades. Historical context and background are given, and the project's…

With an initial requirement to make observations a minimum of 5-10 years, Hubble Space Telescope (HST) has continued to operate well for 30 years. It has relied upon five servicing missions to repair and replace essential components. Since the final Space Shuttle mission 10 years ago it has avoided major breaks in its…

'Christophe Le Poncin-Lafitte' 'Mario Gai' 'Qi Zhaoxiang' 'Alberto Vecchiato'] The direct detection of gravitational waves by ground-based optical interferometers has opened a new window in astronomy. Besides, the sensitivity of these linear detectors to the direction of arrival of an incoming gravitational wave is…

Metal-based chalcogenides exhibit great promise for overall water splitting, yet their intrinsic catalytic reaction mechanisms remain to be fully understood. In this work, we employed operando X-ray absorption (XAS) and in situ Raman spectroscopy to elucidate the structure-activity relationships of low-crystalline…

The regulation of miRNA biogenesis and movement is essential for plant development and environmental responses. HASTY (HST), a karyopherin protein, has been implicated in miRNA biogenesis and movement, though its role in non-cell-autonomous miRNA movement remains unclear. Through a genetic screen, we identified that…

We describe $\texttt{stistools.barycentric_correction}$, a new Python utility for calculating barycentric timing corrections for HST/STIS observations. This tool replaces the deprecated $\texttt{stsdas.hst_calib.stis.odelaytime}$ IRAF function that was previously used for HST barycentric corrections. Our new utility…

'Toshihiro Fujii' 'Yutaka Komiyama' 'Satoshi Miyazaki' 'Tomoki Morokuma' 'Hitoshi Murayama' 'Masamune Oguri' 'Tsuyoshi Terai'] Extensive air showers induced from high-energy cosmic rays provide a window into understanding the most energetic phenomena in the universe. We present a new method for observing these showers…

finalities, and measurements Authors: Harley E. A. Bicas The paper starts discussing the teleological concept that eye motions - rotations and translations - serve to vision (which supports the notion that torsions are not voluntarily driven, since they do not contribute to expand the visual exploration of space). It…

Classical and quantum mechanics laws are rebuilt in the framework of new thermodynamics: Electrons condense to form the hot protons and cool protons (neutrons), and then construct the nucleus by the thermal difference force. An atom is an adiabatic electron-gas system. Heat is the sum of variations in kinetic energy…

Most co-orbital objects in the Solar system are thought to follow tadpole-type orbits, behaving as Trojans. However, most of Earth's identified co-orbitals are moving along horseshoe-type orbits. The current tally of minor bodies considered to be Earth coorbitals amounts to 18; of them, 12 are horseshoes, five are…

In the diagnosis of strabismus due to paralysis of the eye muscles, the Hess screen test and the Harms tangent screen test are used to measure the misalignment of the eyes in different gaze directions (motility analysis). Both examination methods use different procedures to define the gaze direction and coordinate…
