Images captured in low-light conditions often suffer from poor visibility and noise corruption. Low-light image enhancement (LLIE) aims to restore the brightness of under-exposed images. However, most previous LLIE solutions enhance images via global mapping without considering various degradations dark regions. Besides, these methods rely on convolutional neural networks for training, which have limitations capturing long-range dependencies. To this end, we construct a hybrid framework...

Using a data sample of $1.31 \times 10^{9}$ $J/\psi$ events accumulated with the BESIII detector, decay $J/\psi\to p\bar{p}\phi$ is studied via two modes, $\phi\to K^{0}_{S}K^{0}_{L}$ and K^{+}K^{-}$. The branching fraction measured to be $\mathcal{B}(J/\psi\to p\bar{p}\phi)=[5.23\pm0.06(\mbox{stat})\pm0.33(\mbox{syst})]\times10^{-5}$, which agrees well previously published measurement, but significantly improved precision. No evident enhancement near $p\bar{p}$ mass threshold, denoted as...
Using $2.92$ fb$^{-1}$ of electron-positron annihilation data collected at $\sqrt{s} = 3.773$~GeV with the BESIII detector, we report results a search for flavor-changing neutral current process $D^0\to\gamma\gamma$ using double-tag technique. We find no signal and set an upper limit $90\%$ confidence level branching fraction $B(D^0\to\gamma\gamma) < 3.8\times10^{-6}$. also investigate $D^0$-meson decay into two pions, obtaining $B(D^0\to\pi^0\pi^0)...

ABSTRACT Image segmentation software (SegSoftware) is a kind of DNN‐based image analysis that aims to recognize the shapes and categories instances according their implicit semantic information. SegSoftware frequently uses in safety‐critical fields. Therefore, we should provide adequate testing SegSoftware. Due high cost manually acquiring oracle for SegSoftware, employ metamorphic detect its erroneous behaviour. This paper proposes SegTest, method primarily addresses two major challenges...
A stagger-tuned wide-band transducer based on the principle of amplifier has been developed. number strip-shaped PZT-5A elements with different resonant frequencies were arranged according to tuning theory. The results experiments indicate that frequency response is very good over a fairly large range. bandwidth designed for range 2-3 MHz about 1.36 MHz, whereas single-element only 0.05 MHz. Moreover, as compared transducer, it gives far more abundant blood-flow information.< <ETX...
