The crystal phase of a catalyst support, such as TiO2, significantly contributes to the activity and stability metal-loaded catalysts by modifying metal–support interactions. However, effect on hydrogen spillover-induced hydrodeoxygenation (HDO) is relatively less understood, although spillover reducible oxide support could play crucial role in HDO providing additional active sites. guaiacol was investigated confirming synergetic when pristine rutile anatase TiO2 were added Ru-loaded while...

The physically mixed Co/TiO 2 and WO 3 /TiO catalysts exhibited excellent catalytic performance in the hydrodeoxygenation of guaiacol, deactivated catalyst could be successfully regenerated after magnetic separation.

Abstract Hydrodeoxygenation (HDO) of lignin-derived pyrolysis oil has received significant attention as a potential technology for replacing conventional petroleum-based fuels and chemicals. Ru-based HDO catalysts are in the limelight since they exhibit excellent catalytic activity while being cost-effective compared to other noble metal-based catalysts. Various studies have reported used its model compounds, variety strategies been utilized tune properties enhance performance advance...

*† ‡ § ** The demand for realistic autonomous virtual humans is increasing, with potential application to prototype design and analysis a reduction in cycle time cost. In addition, that function independently, without input from user or database of animations, provide convenient tool biomechanical studies. However, development such avatars limited. this paper, we capitalize on the advantages optimization-based posture prediction humans. We extend approach by incorporating multi-objective...

Deriving insights from the global production network (GPN) framework, we examine recent development of liquid crystal display (LCD) industry in South Korea. Using GPN focus on role national state as an active inter-scalar mediator dynamic strategic coupling process between leading firms and local actors globalizing regional development. We argue that was crucial coordinating localized growth factors with external to create develop LCD industry. This achievable because legacy developmental...

This paper introduces a novel surgical robot for single-incision laparoscopic surgeries. The system includes the cone-type remote center-of-motion (RCM) mechanism and two articulated instruments having flexible linkage-driven elbow. RCM mechanism, which has revolute joints one prismatic joint, is designed to maintain stationary point at apex of cone shape. By placing on incision area, allows instrument explore abdominal area through small point. have six joints, including an elbow pitch make...

This paper develops a signal optimization algorithm that aims to equalize queue growth rates across links in oversaturated urban roadway networks and thus postpones spillbacks form at the localized sections of networks. The performance this is evaluated by simulating traffic conditions with optimized settings on an idealized 3 network under various demand scenarios. simulation experiments show can delay distributing queues over upstream would otherwise be underused. findings from also...

Recent progress in genetic manipulation of pigs designated for xenotransplantation ha6s shown considerable promise on xenograft survival primates. However, modification multiple genes donor by knock-out and knock-in technologies, aiming to enhance immunological tolerance against transplanted organs the recipients, has not been evaluated health issues pigs. We produced transgenic Massachusetts General Hospital piglets knocking-out α-1,3-galactosyltransferase (GT) gene simultaneously...

Shared mobility is a service that allows users to share various transportation modes and use them with reservations when necessary. It started private automotive car-sharing ride-sharing services. Currently, it operates on wider range, including personal devices such as electric bicycles scooters. The purpose of this study derive direction for providing future shared services through analysis factors affecting the usage intention both current prospective users. survey targets 753 citizens...

The unstructured-textual crash descriptions recorded by police officers is rarely utilized, despite containing detailed information on traffic situations. This lack of utilization mainly due to the difficulty in analyzing text data, as there currently no innovative methodology for extracting meaningful from it. Given limitations and challenges descriptions, this study developed a classify significant words unstructured data that describe scenarios into standardized data. Ultimately, natural...

In this paper we examine the role of Korean government in creating university – industry linkages and promoting universities as knowledge providers regional innovation systems. We investigate different types universities' roles capital region Seoul noncapital regions. argue that policy is main determinant drives to play provider for industrial innovation. This has also brought about differences way participate activities outside region. context, regions act a backbone managing networks well...

Mobility as a service (MaaS) integrates various transportation modalities and connects these to enable users travel from departure points destination points. The objectives of this study were analyze the factors influencing intention use MaaS determine direction for implementation service. Hence, utilized an ordered probit model marginal effect analysis. Specifically, survey was conducted based on citizens living in Gyeonggi-do, South Korea, prepare logical operation measures customized...

Long-Term Evolution (LTE) is a fourth-generation mobile communication technology implemented throughout the world. It means of smartphones that send and receive all private date individuals. M2M, IOT, etc., are base technologies will be used in future cyber However, identification parameters, such as International Mobile Subscriber Identity (IMSI), Radio Network Temporary Identities (RNTI), initial attach section for accessing LTE network presented with vulnerability being exposed clear...

Estimated travel speed based on spot measurements from detectors has been used as a proxy to actual speed. Recently, speeds become available vehicles with onboard electronic devices provide section times. As result, two different can be estimated for freeway at time interval: takes the average of collected each detector within interval, and is using sampled vehicles' journey over section. This paper compares difference between both kinematic wave theory observations traffic states. The...

The authors create a weekly investor sentiment index for Korea using Internet search volume, which directly reflects almost every household's concerns about the market. In addition, they analyze how affects aggregate market and investors' trading behavior. results show that predicts positive future return reversal after 3 weeks, temporary increase in volatility, shift fund preferences from equity funds to money reverses weeks. Furthermore, an authors' coincides with individuals selling...
