Fair Peer Assignment Scheme for Peer-to-Peer File Sharing
( Chih-lin Hu ),( Da-you Chen ),( Yi-hsun Chang ),( Yu-wen Chen ) 한국인터넷정보학회 2010 KSII Transactions on Internet and Information Syst Vol.4 No.5
The reciprocal virtue of peer-to-peer networking has stimulated an explosion of peer population and service capacity, ensuring rapid content distribution in peer-to-peer networks. Critical issues such as peer churn, free riding, and skewed workload significantly affect performance results such as service agility, fairness, and resource utilization. To resolve these problems systematically, this study proposes a peer assignment scheme that supports fair peer-to-peer file sharing applications. The proposed scheme exploits the peer duality of both server-oriented peer capacity and client-oriented peer contribution. Accordingly, the system server can prioritize download requests and appropriately assign server peers to uploading file objects. Several functional extensions, including peer substitution and elimination, bandwidth adjustment, and distributed modification, help cope with subtle situations of service starvation and download blocking, and hence make the system design robust and amenable. Simulation results show this design is examined under both centralized and distributed peer-to-peer environments. Performance results confirm that the proposed mechanisms are simple but effective in maintaining service agility and fairness, without loss of overall service capacity in peer-to-peer files sharing systems.

A P2P-to-UPnP Proxy Gateway Architecture for Home Multimedia Content Distribution
( Chih-lin Hu ),( Hsin-cheng Lin ),( Yu-feng Hsu ),( Bing-jung Hsieh ) 한국인터넷정보학회 2012 KSII Transactions on Internet and Information Syst Vol.6 No.1
Deploying advanced home networking technologies and modern home-networked devices in residential environments provides a playground for new home applications and services. Because home multimedia entertainment is among the most essential home applications, this paper presents an appealing home media content sharing scenario: home-networked devices can discover neighboring devices and share local media content, as well as enormous amounts of Internet media content in a convenient and networked manner. This ideal scenario differs from traditional usages that merely offer local media content and require tedious manual operations of connection setup and file transfer among various devices. To achieve this goal, this study proposes a proxy gateway architecture for home multimedia content distribution. The proposed architecture integrates several functional mechanisms, including UPnP-based device discovery, home gateway, Internet media provision, and in-home media content delivery. This design addresses several inherent limitations of device heterogeneity and network interoperability on home and public networks, and allows diverse home-networked devices to play media content in an identical and networked manner. Prototypical implementation of the proposed proxy gateway architecture develops a proof-of-concept software, integrating a BitTorrent peer-to-peer client, a UPnP protocol stack, and a UPnP AV media server, as well as media distribution and management components on the OSGi home gateway platform. Practical demonstration shows the proposed design and scenario realization, offering users an unlimited volume of media content for home multimedia entertainment.

A Novel Mobile Content Delivery Scenario with Simple Double-Key Secure Access Control
Chih-Lin Hu,Chien-An Cho 보안공학연구지원센터 2009 International Journal of Security and Its Applicat Vol.3 No.1
Under the convergence of fixed and mobile network systems, modern networked devices are often equipped with multiple connectivity modules so that users can access various information services, by means of portable information devices, anytime and anywhere over ubiquitous Internet access connectivity. In this paper, we present a novel secure mobile content delivery mechanism where networked devices in a vicinity can discover each other, transfer media contents in a convenient, networked method instead of ordinary transfer method that involves unfriendly manual operations of connection setup and file transfer. Its design integrates several significant components, including device discovery, mobile content delivery and double-key secure access control, which are able to alleviate several inherent limitations in wireless and mobile networks. It thus enables mobile handheld devices to escape from mobility confinement and to transfer media contents in an efficient, energy-saving and secure manner.

Graphite-based selectorless RRAM: improvable intrinsic nonlinearity for array applications
Chen, Ying-Chen,Hu, Szu-Tung,Lin, Chih-Yang,Fowler, Burt,Huang, Hui-Chun,Lin, Chao-Cheng,Kim, Sungjun,Chang, Yao-Feng,Lee, Jack C. The Royal Society of Chemistry 2018 Nanoscale Vol.10 No.33
<P>Selectorless graphite-based resistive random-access memory (RRAM) has been demonstrated by utilizing the intrinsic nonlinear resistive switching (RS) characteristics, without an additional selector or transistor for low-power RRAM array application. The low effective dielectric constant value (<I>k</I>) layer of graphite or graphite oxide is utilized, which is beneficial in suppressing sneak-path currents in the crossbar RRAM array. The tail-bits with low nonlinearity can be manipulated by the positive voltage pulse, which in turn can alleviate variability and reliability issues. Our results provide additional insights for built-in nonlinearity in 1<I>R</I>-only selectorless RRAMs, which are applicable to the low-power memory array, ultrahigh density storage, and in-memory neuromorphic computational configurations.</P>

Discontinuation Rate of Newly Prescribed Donepezil in Alzheimer's Disease Patients in Asia
박기형,양영순,Chen Christopher,심용수,Domingueze Jacqueline C.,이찬녕,강경훈,김희진,정슬기,정지향,Hong Zhen,윤수진,Zhang Zhen-Xin,김은주,장재원,Li Yansheng,Xu Yun,Lin Yu-Te,Qu Qiumin,Hu Chaur-Jong,Chou Chih-Ho,Fan Dongsheng,Kandiah N 대한신경과학회 2021 Journal of Clinical Neurology Vol.17 No.3
Background and Purpose The rate of donepezil discontinuation and the underlying reasons for discontinuation in Asian patients with Alzheimer’s disease (AD) are currently unknown. We aimed to determine the treatment discontinuation rates in AD patients who had newly been prescribed donepezil in routine clinical practice in Asia. Methods This 1-year observational study involved 38 institutions in seven Asian countries, and it evaluated 398 participants aged 50–90 years with a diagnosis of probable AD and on newly prescribed donepezil monotherapy. The primary endpoint was the rate of donepezil discontinuation over 1 year. Secondary endpoints included the reason for discontinuation, treatment duration, changes in cognitive function over the 1-year study period, and compliance as assessed using a clinician rating scale (CRS) and visual analog scale (VAS). Results Donepezil was discontinued in 83 (20.9%) patients, most commonly due to an adverse event (43.4%). The mean treatment duration was 103.67 days in patients who discontinued. Among patients whose cognitive function was assessed at baseline and 1 year, there were no significant changes in scores on the Mini-Mental State Examination, Montreal Cognitive Assessment, and Trail-Making Test–Black and White scores, whereas the Clinical Dementia Rating score increased significantly (p<0.001). Treatment compliance at 1 year was 96.8% (306/316) on the CRS and 92.6±14.1% (mean±standard deviation) on the VAS. Conclusions In patients on newly prescribed donepezil, the primary reason for discontinuation was an adverse event. Cognitive assessments revealed no significant worsening at 1 year, indicating that continuous donepezil treatment contributes to the maintenance of cognitive function.
