The observation of the transient sky through a multitude astrophysical messengers hasled to several scientific breakthroughs these last two decades thanks fast evolution ofthe observational techniques and strategies employed by astronomers. Now, it requiresto be able coordinate multi-wavelength multi-messenger follow-up campaign withinstruments both in space on ground jointly capable scanning large fraction thesky with high imaging cadency duty cycle. In optical domain, key challengeof wide...
In this paper, we report the detection and follow-ups of a super stellar flare GWAC\,181229A with an amplitude $\Delta R\sim$9.5 mag on M9 type star by $\text{SVOM/GWAC}$ dedicated follow-up telescopes. The estimated bolometric energy $E_{bol}$ is $(5.56-9.25)\times10^{34}$ ergs, which places event to be one most powerful flares ultracool stars. magnetic strength inferred (3.6-4.7) kG. Thanks sampling cadence 15 seconds, new component near peak time very steep decay detected in $R$-band...
Abstract Biofiltration is an effective technology for the treatment of gaseous waste. However, a biofiltration system needs bioreactor large volume and it slow to adapt fluctuating concentrations in waste gas. To overcome these disadvantages, bench‐scale integrating biofilter adsorption unit gases containing o ‐xylene was investigated this study. The packed with granule active carbon (GAC). results showed that 90% could be removed at inlet concentration below 900 mg/m 3 . maximum elimination...
Abstract The discovery of spectral type transition active galactic nuclei (AGNs), the so-called “changing-look” (CL) phenomenon, challenges widely accepted AGN paradigm, not only in orientation-based unified model, but also standard disk model. In past decades, a couple nearby repeat changing-look (CL-AGNs) have been identified. Here we report spectroscopic observations UGC 3223 over course 18 yr, from 2001 onwards. Combining spectrum taken 1987 by Stirpe, witnessed its transitions <?CDATA...
Abstract Multiwavelength simultaneous observations are essential to the constraints on origin of fast radio bursts (FRBs). However, it is a significant observational challenge due nature FRBs as transients with millisecond duration, which occur randomly in sky regardless time and position. Here, we report search for short-time optical Ground-based Wide Angle Camera (GWAC) archived data associated FRB 20181130B, were detected by Five-hundred-meter Aperture Spherical Telescope recently...
This study focuses on improving short-term power load forecasting, a critical aspect of system planning, control, and operation, especially within the context China’s "dual-carbon" policy. The integration renewable energy under this policy has introduced complexities such as nonlinearity instability. To enhance forecasting accuracy, VMD-SE-BiSATCN prediction model is proposed. improves computational efficiency reduces errors by analyzing reconstructing sequence component complexity using...
LS I +61$^{\circ}$ 303 is one of around ten gamma-ray binaries detected so far which has a spectral energy distribution dominated by MeV-GeV photons. It located at distance 2 kpc and consists compact object (black hole or neutron star) in an eccentric orbit 10-15 $M_{\odot}$ Be star, with orbital period 26.496 days. The binary modulates the emission ranging from radio to TeV energies. A second, longer, modulation 1667 days (the super-orbital period) also been observations. VERITAS imaging...
