In this paper, we present a model deformation approach based on a visual hull technique for improving 3D reconstruction. The proposed approach combines the exquisite 3D model derived by active acquisition methods and the constraints from the rough 3D model derived by passive methods. We take the advantages of active and passive methods to obtain a 3D model with the better quality. The clustering method is adopted to segment 3D models into several sub-models and we then match the sub-models individually via an iterative closest point algorithm. Three testing 3D models are used for evaluating the proposed approach. The results demonstrate the feasibility of the proposed approach.

Using a data-set from the ASEAN-5 countries over the January 2000–August 2013 period, this paper revisits the Granger causal nexus between the equity and foreign exchange markets by employing the bootstrap panel Granger causality approach developed by Kònya, which allows for both cross-sectional dependency and heterogeneity across countries. The results indicate a unidirectional causality from stock prices to exchange rates in Malaysia, the Philippines and Thailand and from exchange rates to stock prices in Indonesia. These findings have important implications for policy-makers and institutional investors who should rigidly monitor the dynamic linkages between stock price and exchange rate movements across the ASEAN-5 financial markets when making policy decisions and investing in these countries.

Angiotensin II (Ang II) is a very important cardiovascular disease inducer and may cause cardiac pathological hypertrophy and remodeling. We evaluated a Chinese traditional medicine, alpinate oxyphyllae fructus (AOF), for therapeutic efficacy for treating Ang II-induced cardiac hypertrophy. AOF has been used to treat patients with various symptoms accompanying hypertension and cerebrovascular disorders in Korea. We investigated its protective effect against Ang II-induced cytoskeletal change and hypertrophy in H9c2 cells. The results showed that treating cells with Ang II resulted in pathological hypertrophy, such as increased expression of transcription factors NFAT-3/p-NFAT-3, hypertrophic response genes (atrial natriuretic peptide [ANP] and b-type natriuretic peptide [BNP]), and Gαq down-stream effectors (PLCβ3 and calcineurin). Pretreatment with AOF (60–100 μg/mL) led to significantly reduced hypertrophy. We also found that AOF pretreatment significantly suppressed the cardiac remodeling proteins, metalloproteinase (MMP9 and MMP2), and plasminogen activator, induced by Ang II challenge. In conclusion, we provide evidence that AOF protects against Ang II-induced pathological hypertrophy by specifically inhibiting the insulin-like growth factor (IGF) II/IIR-related signaling pathway in H9c2 cells. AOF might be a candidate for cardiac hypertrophy and ventricular remodeling prevention in chronic cardiovascular diseases.

A series of nanocatalysts derived from immobilization of palladium nanoparticles (Pd NPs) into threedimensional (3D) tube-type architecture of nitrogen (N) functionalized and without functionalized mesoporouscarbon CMK-9 is developed by dual agents chemical reduction approach. Herein, for the first timeN-functionalized CMK-9 is explored as supports to immobilize Pd NPs and use as multifunctional catalystsfor Suzuki-Miyaura cross-coupling reaction, reduction of 4-nitrophenol and hydrodechlorinationof chlorobenzene. The Pd@N-CMK-9 catalysts show excellent activities with 100% conversion forSuzuki-Miyaura reaction between iodobenzene and phenylboronic acid and turnover frequency up to1992 h 1. When use as catalyst for reduction of 4-nitrophenol to 4-aminophenol, it delivers an outstandingrate constant of 4.22 10-2 s 1 with activity parameter of 51719 s-1g 1 with respect to only Pd content. The nanocatalysts also demonstrate 100% conversion of chlorobenzene to benzene within 1 h. Inaddition, the catalyst exhibits remarkable catalytic stability for several cycles without any significant lossof products. The excellent catalytic activities can be attributed to synergistic effect of uniformly dispersedPd NPs, favorable interaction between metal and support, and tubular interconnected mesoporous frameworkof N-functionalized CMK-9 that accelerate mass transportation. The present work signifies the versatilityof Pd@N-CMK-9 nanocatalysts for various catalytic reactions.
