Photosynaptic organic field-effect transistors (OFETs) represent a viable pathway to develop bionic optoelectronics. However, the high operating voltage and current of traditional photosynaptic OFETs lead huge energy consumption greater than that real biological synapses, hindering their further development in new-generation visual prosthetics artificial perception systems. Here, fully solution-printed OFET (FSP-OFET) with substantial reduction is reported, where source Schottky barrier...
Organic photodetectors, as an emerging wearable photoplethysmographic (PPG) technology, offer exciting opportunities for next-generation photonic healthcare electronics. However, the mutual restraints among photoresponse, structure complexity, and fabrication cost have intrinsically limited development of organic photodetectors ubiquitous health monitoring in daily activities. Here, effective route to dramatically boost performance with a solution-processed integration circuit application is...

Abstract We present the first search for pulsed CH maser emission potentially stimulated by PSR~J1644$-$4559, conducted using ultra-wide-bandwidth low-frequency receiver on Murriyang, CSIRO's Parkes Radio Telescope. Observations targeted three $\Lambda$-doublet transitions at 3264, 3335, and 3349 MHz, with a variability timescale of 78 ms. detected ten features 3335 seven 3264 during both pulsar-ON pulsar-OFF phases. The observed velocities align OH absorption reported previous study,...

Automatic cleaning of carbon blocks based on machine vision is currently an important aspect industrial intelligent applications. The recognition block types and center point localization are the core contents this task, but existing instance segmentation algorithms perform poorly in task. This paper proposes algorithm improved YOLOv8 (YOLOv8-HDSA), which achieves highly accurate edge segmentation. YOLOv8-HDSA designs a Selective Reinforcement Feature Fusion Module (SRFF) that utilizes...
Abstract The properties of host galaxies associated with fast radio bursts (FRBs) provide critical information for inferring the progenitors and radiation mechanisms these bursts. We report on galaxy repeating FRB 20190520B, a dwarf at spectroscopic redshift z = 0.241 stellar mass (6.2 ± 0.8) × 10 8 M ⊙ . emission-line ratios suggest that ionized gas is powered by star formation. total H α -traced formation rate (SFR) 0.70 0.01 yr −1 , metallicity <mml:math...
Understanding the molecular gas content in interstellar medium (ISM) is crucial for studying star formation and galaxy evolution. The CO-to-H_2 (X_ CO) C i -to-H_2 CI) conversion factors are widely used to estimate mass galaxies. However, these depend on many environmental parameters ISM, such as metallicity, cosmic-ray ionization rate, far-ultraviolet (FUV) radiation field, particular, low-metallicity ISM that found at large galactocentric radii early-type This work investigates dependence...
Abstract We investigated H i absorption toward a single pulsar, PSR J1644−4559, and its variability over timescales from days to years, using Murriyang, CSIRO’s Parkes Radio Telescope. Our 19 epochs of spectral observations, spanning 1.2 yr with intervals as short 1 day, provide the most comprehensive cadence coverage for monitoring date. identified two significant detections tiny-scale atomic structure (TSAS) spatial scales ranging lower limit ∼11 au an upper 165 au, both exhibiting...

Narrow-band-gap Sn-Pb perovskites have emerged as one of the most promising solution-processed near-infrared (NIR) light-detection technologies, with key figure-of-merit parameters already rivaling those commercial inorganic devices, but maximizing cost advantage optoelectronic devices depends on ability to fast-speed production. However, weak surface wettability perovskite inks and evaporation-induced dewetting dynamics limited solution printing uniform compact films at a high speed. Here,...

The cosmic-ray ionization rate (CRIR, $\zeta_2$) is one of the key parameters controlling formation and destruction various molecules in molecular clouds. However, current most commonly used CRIR tracers, such as H$_3^+$, OH$^+$, H$_2$O$^+$, are hard to detect require presence background massive stars for absorption measurements. In this work, we propose an alternative method infer diffuse clouds using abundance ratios OH/CO HCO$^+$/CO. We have analyzed response chemical abundances CO, OH,...
Since 1996, a hybrid experiment consisting of the emulsion chamber and burst detector array Tibet-II air-shower has been operated at Yangbajing (4300 m above sea level, 606 g/cm2) in Tibet. This can detect cores, called events, accompanied by air showers excess about 100 TeV. We observed 4300 events during 690 days operation selected 820 proton-induced with its primary energy 200 TeV using neural network method. Using this data set, we obtained spectrum protons range from to 1000 The...

Two mutants of the enzyme rhodanese that replace Arg-186 with Leu (R186L) or Lys-249 Ala (K249A) were prepared to test suggestions these residues are involved in catalysis and structure. The predominant effect R186L was functional, Km for sulfur donor, thiosulfate, increased from 3.7 mM 73 a modest decrease Vmax (672 IU/mg 576 IU/mg). However, K249A virtually inactive using but it active thiosulfonates such as p-toluene-, 2-aminoethane-, ethanethiosulfonate, compounds could be demonstrated...
