Asian Economic Integration - Perspectives from a Chinese Scholar
Full text linkSince the 1990s, regional economic integration has become an unstoppable trend throughout the world. As the most telling feature of that, regional trade agreements (RTAs) have expanded explosively in the past fifteen years (see figure 1). According to the latest WTO data, the number of RTAs of all kinds (including those in implementation or to be signed) had reached almost 300 by the end of 2005. 250 of them have been notified to WTO, among which 130 were notified after January 1995, with most signed recently. So far, 173 RTAs have been notified to WTO and taken effect. It is assessed that there are still over 70 RTAs which havent been notified to WTO but about to come into effect.Asian Economic Integration

It can generate photogenerated carriers that actively participate in photocatalytic reactions. Strategies such as molecular catalysts, doping, ligands, junctions, and band edge adjustment enhance photon utilization. Current applications focus on simple reactions, necessitating further exploration into complex reactions with selectivity challenges. This study emphasizes designing semiconductor-based nanomaterials for photocatalysis, optimizing structure configurations, and understanding the relationship between structure and chemical reaction mechanisms. In this study, we have developed a high-performance photocatalyst for C-C coupling of benzyl alcohol and dry reforming of methane. In the former part, CdS-based photocatalyst for synthesizing HB with precisely controlled surface properties and structure, achieving high selectivity for HB synthesis by C-C coupling of benzyl alcohol. We employed strategies such as cysteamine passivation and Pt deposition to address issues related to photogenerated charge trapping and recombination, thereby enhancing the photocatalytic capability of CdS. With optimized Pt/CdS NSs as the photocatalyst, we investigated the impact of the Pt/CdS heterostructure on intermediate reactions, which in turn altered product selectivity. Specifically, excessive Pt suppresses the electron-induced benzaldehyde-to-intermediate reaction by consuming electrons for competing hydrogen evolution reaction (HER), leading to high selectivity toward benzaldehyde. In contrast, bare CdS without Pt suffers from insufficient charge supply for BzOH conversion due to the charge recombination issue, which promotes the subsequent conversion of HB to its derivatives. Notably, when Pt is precisely loaded to avoid dominant HER competition, the overall reaction rate increases, maintaining high selectivity towards HB and ensuring faster conversion of BzOH to HB rather than subsequent conversions of HB into its derivatives, thereby maximizing the HB yield. Subsequently, we have developed a photocatalyst that achieves a 93.4% conversion of 0.24 mmol BzOH with 85.3% selectivity toward HB under solar simulator irradiation (AM 1.5G). In the latter part, we studied the dry reforming of methane by using Cu-loaded TiO2. We investigated the impact of loaded Cu on the adsorption of reactants and reaction mechanisms. Specifically, the reversible Cu2+/Cu+ couple help with the oxygen exchange between CH4 and CO2, which is the driven force for the reaction. This work is expected to offer instructive guidance on rationally designing the photocatalyst.한국과학기술원 :생명화학공학과

A coupled meshless technique/molecular dynamics approach for deformation characterization of monocrystalline metal
No full textThis paper presents a multiscale study using the coupled Meshless technique/Molecular Dynamics (M2) for exploring the deformation mechanism of mono-crystalline metal (focus on copper) under uniaxial tension. In M2, an advanced transition algorithm using transition particles is employed to ensure the compatibility of both displacements and their gradients, and an effective local quasi-continuum approach is also applied to obtain the equivalent continuum strain energy density based on the atomistic poentials and Cauchy-Born rule. The key parameters used in M2 are firstly investigated using a benchmark problem. Then M2 is applied to the multiscale simulation for a mono-crystalline copper bar. It has found that the mono-crystalline copper has very good elongation property, and the ultimate strength and Young's modulus are much higher than those obtained in macro-scale
FPGA Acceleration of 3D FDTD for Multi- Antennas Microwave Imaging Using HLS
Full text linkMicrowave Imaging (MI) for biomedical applications has attracted attention due to its harmless radiation compared to X-ray or MRI. One of the commonly used computing methods in MI is Finite Difference Time Domain (FDTD), which is executed several times in iterative loops, hence resulting in a high execution time. Although several hardware accelerators for FDTD have been recently introduced, they are not specifically designed for MI applications. In particular, only simple absorbing boundary conditions have been investigated, and the impact of dispersive materials on FDTD has not been considered. In this paper, we propose a multi-FPGA accelerator for 3D FDTD that is integrated in an MI algorithm, with Convolutional Perfectly Matched Layer (CPML) boundary conditions and an exact model for dispersive materials. By using High Level Synthesis (HLS), we obtain an optimized hardware accelerator that uses an efficient blocking method to reduce the data transfer time between external and local memories. We propose two alternative architectures that trade off performance and resource usage. In addition, our code, being developed at a high level, can also be run on GPUs whenever necessary. The results show that our multi-FPGA accelerator is superior to three similar GPU-based designs in terms of execution time and power consumption
Uncovering Plagiarism - Author Profiling at PAN
Full text link[ES] PAN is a yearly workshop and evaluation lab on uncovering plagiarism, authorship, and social software misuse. Since 2009, PAN has been organizing benchmark activities on uncovering plagiarism, authorship, and social software misuse . An additional task - author profiling - has also recently been proposed. Author profiling, instead of focusing on individual authors, studies how language is shared by a class of people. Author profiling is a problem of growing importance in applications in forensics, security and marketing. For instance, a person working in the area of forensic linguistics may need to know the linguistic profile of a suspected text message (language used by a certain type of person) and identify characteristics (with language as evidence). Similarly, from a marketing viewpoint, companies may be interested in determining, through the analysis of blogs and online product reviews, what types of people like or dislike their products.Rosso, P.; Rangel Pardo, FM.
