Single Image Reflection Separation via Component Synergy

The reflection superposition phenomenon is complex and widely distributed in the real world, which derives various simplified linear and nonlinear formulations of the problem. In this paper, based on the investigation of the weaknesses of existing models, we propose a more general form of the superposition model by introducing a learnable residue term, which can effectively capture residual information during decomposition, guiding the separated layers to be complete. In order to fully capitalize on its advantages, we further design the network structure elaborately, including a novel dual-stream interaction mechanism and a powerful decomposition network with a semantic pyramid encoder. Extensive experiments and ablation studies are conducted to verify our superiority over state-of-the-art approaches on multiple real-world benchmark datasets.

Band structures of II-VI semiconductors using Gaussian basis functions with separable ab initio pseudopotentials: Application to prediction of band offsets

We describe the implementation of a separable pseudopotential into the dual space approach for ab initio density-functional calculations using Gaussian basis functions. We apply this Gaussian dual space method (GDS/DFT) to the study of II-VI semiconductors (II=Zn, Cd, Hg; VI=S, Se, Te, Po). The results compare well with experimental data and demonstrate the general transferability of the separable pseudopotential. We also introduce a band-consistent tight-binding (BC-TB) model for calculating the bulk contributions to the valence-band offsets (VBO’s). This BC-TB approach yields good agreement with all-electron ab initio GDS/DFT results. Comparisons between BC-TB results of VBO obtained with and without p-d coupling demonstrate quantitatively the importance of d electrons and cation-d–anion-p coupling in II-VI systems. Agreement between ab initio results and experimental results is excellent

Technology Transition in the National Air Transportation System: Market Failure and Game Theoretic Analysis with Application to ADS-B

Air traffic demand is increasing, but capacity is constrained by an antiquated air traffic control (ATC) infrastructure. The number of air traffic passengers in the U.S. is expected to grow from 738 million in 2005 to 1 billion in 2015. The number of commercial airline flights is expected to grow from 13 million in 2005 to 15 million in 2015. [22] Figure 1-1 shows the growth in air traffic demand in the United States in recent years.This research was funded by the Federal Aviation Administration's Surveillance and Broadcast Services program under contract DTFA01-C-00030

First principles studies of band offsets at heterojunctions and of surface reconstruction using Gaussian dual-space density functional theory

The use of localized Gaussian basis functions for large scale first principles density functional calculations with periodic boundary conditions (PBC) in 2 dimensions and 3 dimensions has been made possible by using a dual space approach. This new method is applied to the study of electronic properties of II–VI (II=Zn, Cd, Hg; VI=S, Se, Te, Po) and III–V (III=Al, Ga; V=As, N) semiconductors. Valence band offsets of heterojunctions are calculated including both bulk contributions and interfacial contributions. The results agree very well with available experimental data. The p(2 × 1) cation terminated surface reconstructions of CdTe and HgTe (100) are calculated using the local density approximation (LDA) with two-dimensional PBC and also using the ab initio Hartree–Fock (HF) method with a finite cluster. The LDA and HF results do not agree very well

The Impact of Executive Compensation on Real Earnings Management - A Case Study of Chinese Listed Companies

Financial reporting is increasingly becoming a focus of attention in the development of capital markets. The importance of accounting earnings information is also becoming more and more prominent as it provides the basis for economic decisions made by shareholders, creditors and other stakeholders of the company, and his importance is becoming more and more prominent. Real earnings management is the manipulation of corporate sales revenue, production costs and discretionary expenses through the construction of real trading activities for specific purposes, which are relatively hidden, difficult to detect and materially harmful to the business. In a business, the separation of ownership and operation of the business can lead to an inconsistency of interests between the principal and the agent, resulting in agency problems. This can be mitigated by a policy of compensation incentives for executives to maximize their own interests and reduce the likelihood of earnings management. This paper uses pay incentives for executives as an entry point to explore the impact of executive pay levels and the executive pay gap on true earnings management. Data from listed companies in the SSE 50 and FTSE 50 from 2018-2020 are selected to study the impact of executive compensation on real earnings management. The test results show that both executive pay level and executive pay gap are negatively related to the level of real earnings management, the higher the level of executive pay, the lower the level of real earnings management, and the larger the executive pay gap, the lower the level of real earnings management, indicating that the remuneration incentive mechanism in China plays a significant role The higher the level of executive compensation, the lower the level of real earnings management. The negative relationship between executive compensation, executive pay gap and real earnings management is more pronounced in state-owned enterprises than in non-state-owned enterprises, probably because senior managers in non-state-owned enterprises need to maximize corporate profits and face less pressure from the state and society to regulate them harshly.

Fish consumption and CHD mortality: an updated meta-analysis of seventeen cohort studies

Objective Results of studies on fish consumption and CHD mortality are inconsistent. The present updated meta-analysis was conducted to investigate the up-to-date pooling effects. Design A random-effects model was used to pool the risk estimates. Generalized least-squares regression and restricted cubic splines were used to assess the possible dose–response relationship. Subgroup analyses were conducted to examine the sources of heterogeneity. Setting PubMed and ISI Web of Science databases up to September 2010 were searched and secondary referencing qualified for inclusion in the study. Subjects Seventeen cohorts with 315 812 participants and average follow-up period of 15·9 years were identified. Results Compared with the lowest fish intake (\u3c1 serving/month or 1–3 servings/month), the pooled relative risk (RR) of fish intake on CHD mortality was 0·84 (95 % CI 0·75, 0·95) for low fish intake (1 serving/week), 0·79 (95 % CI 0·67, 0·92) for moderate fish intake (2–4 servings/week) and 0·83 (95 % CI 0·68, 1·01) for high fish intake (\u3e5 servings/week). The dose–response analysis indicated that every 15 g/d increment of fish intake decreased the risk of CHD mortality by 6 % (RR = 0·94; 95 % CI 0·90, 0·98). The method of dietary assessment, gender and energy adjustment affected the results remarkably. Conclusions Our results indicate that either low (1 serving/week) or moderate fish consumption (2–4 servings/week) has a significantly beneficial effect on the prevention of CHD mortality. High fish consumption (\u3e5 servings/week) possesses only a marginally protective effect on CHD mortality, possibly due to the limited studies included in this group

Anti-tumor effects of CIK combined with oxaliplatin in human oxaliplatin-resistant gastric cancer cells in vivo and in vitro

<p>Abstract</p> <p>Background</p> <p>Drug resistance remains a great challenge in the treatment of gastric cancer. The goal of this study was to explore the anti-tumor effects and mechanism of cytokine-induced killer (CIK) cell combined with oxaliplatin (L-OHP) in human oxaliplatin-resistant gastric cancer cells.</p> <p>Methods</p> <p>After producing oxaliplatin-resistant gastric cancer cells, cell morphology, growth and doubling time were observed, followed by detection of cell cycle distribution and apoptosis, drug sensitivity (e.g., L-OHP) and expression of P-gp and livin. MTT assay, in vivo pharmacodynamics and pathomorphology experiments were used to detect killing activities of CIK combined with L-OHP.</p> <p>Results</p> <p>Compared with parental gastric cancer cells, oxaliplatin-resistant gastric cancer cells in S phase were reduced and cell apoptosis rate was increased (P < 0.05), the inhibition rate of 10 chemotherapeutics on oxaliplatin-resistant gastric cancer cells was significantly lower and the expression of P-gp was significantly higher (P < 0.05). However, there was no significant difference in livin expression between parental gastric cancer cells and oxaliplatin-resistant gastric cancer cells (P > 0.05). The in vitro killing activity of CIK combined with L-OHP on parental cells and oxaliplatin-resistant cells were significantly enhanced compared with L-OHP or CIK alone. And it showed greater synergetic effects against oxaliplatin-resistant cells compared with parental cells (P < 0.05). In addition, survival rate, abdominal circumference and pathomorphology results revealed stronger in vivo anti-tumor effects when the two therapies were combined.</p> <p>Conclusions</p> <p>The mechanism of oxaliplatin-resistant cell secondary multidrug resistance was correlated with the variation of cell cycle distribution, extension of doubling time and upregulation of P-gp expression. The synergistic effect of CIK in combination with L-OHP on killing activity against oxaliplatin-resistant cells was shown in vivo and in vitro.</p
