This paper reviews the NTIRE 2020 challenge on real image denoising with focus newly introduced dataset, proposed methods and their results. The is a new version of previous 2019 that was based SIDD benchmark. collected validation testing datasets, hence, named SIDD+. has two tracks for quantitatively evaluating performance in (1) Bayer-pattern rawRGB (2) standard RGB (sRGB) color spaces. Each track ~250 registered participants. A total 22 teams, proposing 24 methods, competed final phase...
Dynamin 1 (dyn1) is required for clathrin-mediated endocytosis in most secretory (neuronal and neuroendocrine) cells. There are two modes of Ca 2+ -dependent catecholamine release from single dense-core vesicles: full-quantal (quantal) subquantal adrenal chromaffin cells, but their relative occurrences impacts on total secretion remain unclear. To address this fundamental question neurotransmission area using both sexes animals, here we report the following: (1) dyn1-KO increased quantal...
In this paper, we are concerned with the boundedness of all solutions and existence quasi-periodic for second order differential equations \[ x^{\prime \prime } + g(x) = e(t), \] where 1-periodic function $e(t)$ is a smooth $g(x)$ satisfies sublinearity: \operatorname {sign}(x)\cdot g(x)\to +\infty ,\quad g(x)/x\to 0 \quad {as} |x|\to .
Oblique stripe noise widely appears in remote sensing images after image correction, exhibiting arbitrary tilt angles and parallel distribution. Due to its randomness lengths, oblique increases the difficulty of detection compared vertical or horizontal noise. For first time, we propose a group synthesis algorithms combining imaging mechanisms deep learning. To get controllable synthetic data for training model, two sample augmentation methods are presented by correction's with new linear...
The adrenal gland protein AD‐004 like (ADLP) from Caenorhabditis elegans was cloned and expressed in Escherichia coli . Enzyme assays showed that ADLP has special adenylate kinase (AK) properties, with ATP dATP as the preferred phosphate donors. In contrast to all other AK isoforms, AMP dAMP were substrates of ADLP; CMP, TMP shikimate acid also good substrates. Subcellular localization studies a predominant nuclear for this protein, which is different AK1–AK5, but similar human AK6. These...
We study the second order estimate for unique solution near boundary to singular Dirichlet problem -?u = b(x)g(u); u > 0; x ? ?, u|?? 0, where is a bounded domain with smooth in RN, g C1((0,?),(0?)), decreasing on (0,?) lim s?0+ g(s) 1 and normalized regularly varying at zero index (? 1), b C?(??) (0 < positive may be vanishing boundary. Our analysis based Karamata regular variation theory.
In this paper, we consider the system \[ \dot x=a(t)y^{2m+1}+f_1(x,y,t),\quad y=-b(t)x^{2n+1}+f_2(x,y,t),\] where $m,n\in \mathbf {Z}_+$, $m+n\ge 1$, $a(t)$ and $b(t)$ are continuous, even 1-periodic in time variable $t$; $f_1$ $f_2$ real analytic a neighbourhood of origin $(0,0)$ $(x,y)$-plane continuous $t$. We also assume that above is reversible with respect to involution $G\colon (x,y)\mapsto (-x,y)$. A sufficient necessary condition for stability Liapunov sense equilibrium $(x,y)=(0,0)$ given.
4D ultrasound images of human fetal heart are important for medical applications such as evaluation function and early diagnosis congenital diseases. However, due to the high noise low contrast characteristics in images, denoising enhancements important.In this paper, a special method framework enhancing is proposed. It consists 4D-NLM (non-local means) image sequence, which takes advantage context similar information neighboring denoise target image, an called Adaptive Clipping Each...
With the complexity of IC design increasing, it becomes an emergent issue to reduce cost and short time-t o-market design. In this paper, we propose a high-level synthesis method for Reconfigurable Operator Array. The compiler ReCom is proposed synthesize abstract description low-level hardware description. Meantime, three languages are implement efficiently. To prove advantage method, chose 2 dimension 8bit s DCT algorithm as example which consumes 1500 operators, sum configuration...
In this paper, we describe and analyze a new two-step frequency estimation algorithm for pilot symbol assisted modulation (PSAM) systems with non-uniform pattern. The burst structure includes some consecutive pilots at the beginning of each sparse ones over burst. Compared FFT-based (Fast Fourier Transform based) algorithm, its computational complexity is reduced greatly. It facilitates large offsets high accuracy. Its range about plusmn20% rate accuracy close to Cramer-Rao bound (CRB) low...
In this paper, we describe and analyze an efficient non-date-aided (NDA) symbol timing recovery algorithm named the quadratic approximation (QA) algorithm. Compared with tone filtering (TF) algorithm, presented here is low-complexity. It requires only one multiplication per burst. Its performance better than that of TF in terms estimated standard deviation sensitivity to frequency offsets
