A secure group key management framework: design and rekey issues (2004)

In many secure group communication models, there exists a group manager that creates the group key and distributes it to every group member. Such group manager is responsible for changing and re-distributing (rekeying) the group key whenever it deems necessary. Many applications will require very fast rekeying so that it is not disruptive to their performance. In this paper, we present a generic software model for secure group key management. We present the main components along with their functionality and interactions. With emphasis on the rekey manager, we discuss two issues that critically impact the rekey time: establishment and maintenance of the logical key hierarchy (LKH), and the key packet construction for a changed key. We show that our novel idea of maintaining balanced LKH as B/sup +/ search tree greatly reduces the number of changed keys compared to an unbalanced LKH. In addition, we show that a rekey packet construction using simple XOR operations between keys instead of the usual encryption technique substantially reduces rekey time. We preformed experiments that demonstrate the effectiveness and feasibility of our approaches.
Cloning, expression, and purification of a catalytic fragment of moloney murine leukemia virus reverse transcriptase: Crystallization of nucleic acid complexes (1998)

Reverse transcriptase is an essential retroviral enzyme that uses RNA- and DNA-directed DNA polymerase activities as well as an RNaseH activity to synthesize a double-stranded DNA copy of the single-stranded RNA genome. In an effort to obtain high-resolution structural information regarding the polymerase active site of reverse transcriptase, we have pursued studies on a catalytic fragment from Moloney murine leukemia virus reverse transcriptase. DNA encoding the catalytic fragment, defined originally by limited proteolytic digestion, has been cloned, and the protein has been expressed and purified from Escherichia coli. The fragment obtained by limited proteolytic digestion and the bacterially expressed fragnment retain polymerase activity. Crystallization studies involving nucleic acid complexes with a catalytic fragment from both sources are reported, including variables screened to improve crystals and cryocooling. Three crystal forms of catalytic fragment-nucleic acid complexes have been characterized, which all contain at least two protein molecules in the asymmetric unit. As isolated, the catalytic fragment is monomeric. This analysis indicates that the enzyme dimerizes in the presence of nucleic acid.
Biological Cell Detachment from Poly(<i>N</i>-isopropyl acrylamide) and Its Applications (2009)

Over the past two decades, poly(N-isopropyl acrylamide) (pNIPAM) has become widely used for bioengineering applications. In particular, pNIPAM substrates have been used for the nondestructive release of biological cells and proteins. In this feature article, we review the applications for which pNIPAM substrates have been used to release biological cells, including for the study of the extracellular matrix (ECM), for cell sheet engineering and tissue transplantation, the formation of tumorlike spheroids, the study of bioadhesion and bioadsorption, and the manipulation or deformation of individual cells. The articles reviewed include submissions from our own group as well as from those performing research in the field worldwide.
Coseriu 的模式;交际能力的差异性与普遍性 (1994)

交际能力的概念构成了近年来语言教学思想的基础。说得直接一些,这个概念就是语言的熟练不仅仅意味着了解它的语音、句法、词法与语义,而且是指能够在实际的交际中得体地运用这些知识。运用这些知识还需要其他几方面的知识(例如何时对何人说什么的规则),同时也需要被称之为“控制”的能力或者是“运用的能力”。我们所讨论的知识可以是不言而喻的,
Advances in the Preparation of Fluorinated Isoquinolines: A Decade of Progress (2017)

Heterocyclic molecules incorporating fluorinated isoquinoline components are found in many medicinally and agriculturally important bioactive products as well as industrially impactful materials. Within the past decade, a variety of isoquinolinic ring assembly techniques has enabled the introduction of diverse fluorine-containing functionalities which can enhance potential bioactivity and industrial utility. This review examines recent noncatalyzed and transition metal catalyzed synthetic approaches to the assembly of isoquinoline derivatives that are ring-fluorinated and/or result in the incorporation of fluorine-containing functional groups. Specifically, efficient synthetic methods and regioselectivity in the incorporation of functional groups into isoquinoline ring systems are examined.
DYNACTIN (2004)

Dynactin is a multisubunit protein complex that is required for most, if not all, types of cytoplasmic dynein activity in eukaryotes. Dynactin binds dynein directly and allows the motor to traverse the microtubule lattice over long distances. A single dynactin subunit, p150Glued, is sufficient for both activities, yet dynactin contains several other subunits that are organized into an elaborate structure. It is currently believed that the bulk of the dynactin structure participates in interactions with a wide range of cellular structures, many of which are cargoes of the dynein motor. Genetic studies verify the importance of all elements of dynactin structure to its function. Although dynein can bind some membranous cargoes independently of dynactin, establishment of a fully functional dynein-cargo link appears to depend on dynactin. In this review, I summarize what is presently known about dynactin structure, the cellular structures with which it associates, and the intermolecular interactions that underlie and regulate binding. Although the molecular details of dynactin's interactions with membranous organelles and other molecules are complex, the framework provided here is intended to distill what is presently known and to be of use to dynactin specialists and beginners alike.

They Love New York: American, Continental, JetBlue and Delta Vie for the Keys to the City (2007)

This article about congestion in the key New York City aviation market focuses on the major airlines that use New York and how they intend to respond to anticipated requirements that traffic and activities be cut back to avoid increasing delays. American, JetBlue, Continental and Delta all consider the New York metropolitan region, and the three primary commercial airports that serve it—JFK, LaGuardia and Newark—central to their overall operations. Together the airports handled 107 million passengers in the most recent year for which records are available. Federal intervention at the direction of President George Bush suggests that the U.S. DOT and FAA will be getting involved in programs to ease the crowding. However, it is not clear how it would work. Possible scenarios are discussed, including FAA intervention in scheduling practices.

Subnetwork Root Cause Alarm Analysis - An Element Management Layer (eml) Operations Application (2005)

In response to the constant challenge to provide timely and efficient network management support for new technologies, architectures, and services as such advances become available for deployment, the telecommunications industry (equipment suppliers and networkhervice providers) are investigating alternatives to the traditional ways of viewing and organizing operations functions. The traditional telecommunications operations architecture has generally involved the use of management applications with a network-wide span of control residing in large centralized Operations Systems (OSs). These applications interact with basic operations functions in individual Network Elements (NEs). The evolution of Telecommunications Management Network (TMN) architecture work in standards and other industry efforts have proposed a multi-layered logical operations architecture based on the logical separation (classification) of operations functions in an Element Layer (EL), Element Management Layer (EML), Network Management Layer (NML), and higher layers. Bellcore has also described a target operations computing and communications architecture based on Intelligent Network Architecture (INA) and OSCATM principles for supporting the logical multi-layered architecture. This presentation describes the motivation and basic operations of an EML Fault Management application called Subnetwork Root Cause Alarm Analysis (RCAA). Subnetwork RCAA enables the processing of detailed alarms from NEs within a subnetwork and the reporting of summarized analysis results to network level surveillance applications residing in the NML. The RCAA results identify the root cause failure, characterize its severity, and portray its impact on the transport network. Supporting data required to enable the RCAA application is discussed. The use of the contract interface mechanism from INA for the reporting of RCAA results is briefly reviewed. A particular contract interface specification, using object-oriented information modeling techniques and Common Management Information Service Element / Open Systems Interconnection (CMISE/OSI) protocols is also described.
评《恐怖主义、合法性与权力:政治暴力行为的后果》 (1984)

过去10年内一个庞大的家庭工业连续不断地生产了大批研究恐怖主义的资料,大多数资料含糊其词,有的甚至很糟。这些资料中有的是通俗历史,有的是瞬间捕捉的新闻资料,有的进行惯常的特殊辩解,有著名人士的有见识的评论,也有雄心勃勃的人们进行的详尽研究。在所有这些研究中存在着两种主要倾向,一些人关心的是制定政策,另一些人则是一些利用特定学科工具、各怀特殊兴趣的学者。在政策方面,美国政府已经签署了成千上万页报告,大部分都是旧调重弹,往往很少是适用的。其中有机密文件,也有公开文
Computation of rotation minimizing frames (2008)

Due to its minimal twist, the rotation minimizing frame (RMF) is widely used in computer graphics, including sweep or blending surface modeling, motion design and control in computer animation and robotics, streamline visualization, and tool path planning in CAD/CAM. We present a novel simple and efficient method for accurate and stable computation of RMF of a curve in 3D. This method, called the double reflection method , uses two reflections to compute each frame from its preceding one to yield a sequence of frames to approximate an exact RMF. The double reflection method has the fourth order global approximation error, thus it is much more accurate than the two currently prevailing methods with the second order approximation error—the projection method by Klok and the rotation method by Bloomenthal, while all these methods have nearly the same per-frame computational cost. Furthermore, the double reflection method is much simpler and faster than using the standard fourth order Runge-Kutta method to integrate the defining ODE of the RMF, though they have the same accuracy. We also investigate further properties and extensions of the double reflection method, and discuss the variational principles in design moving frames with boundary conditions, based on RMF.
A six-direction absolute displacement sensor for time-delayed control based on quasi-zero-stiffness property (2016)

A novel six-direction sensor for absolute vibration motion is proposed in this study for the measurement of absolute motions by employing multi-direction quasi-zero-stiffness property. Scissor-like structures with pre-deformed springs are applied symmetrically in the proposed sensor. Based on the mathematical modeling of the proposed six-direction sensor, it is shown that the stiffness and damping properties of the sensor are adjustable nonlinear functions which are dependent on the structural parameters of scissor-like structures. And then, by utilizing bifurcation theory and perturbation method, the structural parameters are optimized for the improvement of measurement accuracy. For the realization of the approximate fixed point for a moving vibration object, the vibration from measurement object to the sensor is isolated, and thus the sensor could obtain the absolute motions. Utilizing the signals obtained by the proposed sensor directly, better vibration/suppression effectiveness is achieved. The results provide a novel and significant six-direction absolute motion measurement method by utilizing multi-direction quasi-zero-stiffness property with noticeable isolation performance only with passive elements.

Open user profiles for adaptive news systems (2007)

Over the last five years, a range of projects have focused on progressively more elaborated techniques for adaptive news delivery. However, the adaptation process in these systems has become more complicated and thus less transparent to the users. In this paper, we concentrate on the application of open user models in adding transparency and controllability to adaptive news systems. We present a personalized news system, YourNews, which allows users to view and edit their interest profiles, and report a user study on the system. Our results confirm that users prefer transparency and control in their systems, and generate more trust to such systems. However, similar to previous studies, our study demonstrate that this ability to edit user profiles may also harm the system.s performance and has to be used with caution.
Estrogen Deficiency–Mediated M2 Macrophage Osteoclastogenesis Contributes to M1/M2 Ratio Alteration in Ovariectomized Osteoporotic Mice (2017)

In this study, for the first time we discovered that the M1/M2 macrophage phenotype ratio is increased in bone marrow of ovariectomized (OVX) osteoporotic C57BL/6 mice. Considering estrogen is the main variable, we assumed that estrogen participated in this alteration. To determine whether and how estrogen contributes to the change of the M1/M2 ratio, we first isolated bone marrow macrophages (BMMs) from mice femur and stimulated the cells with lipopolysaccharide (LPS)/interferon γ (IFN-γ) for M1 polarization and interleukin 4 (IL-4)/IL-13 for M2 polarization. M1 and M2 macrophages were then exposed to RANKL stimulation, we found that M2 macrophage but not M1 macrophage differentiated into functional osteoclast leading to increased M1/M2 ratio. Intriguingly, 17β-estradiol (E2) pretreatment prevented osteoclastogenesis from M2 macrophages. By constructing shRNA lentivirus interfering the expression of different estrogen receptors in M2 macrophages, we found that estrogen protects M2 macrophage from receptor activator of nuclear factor κB ligand (RANKL) stimulation selectively through estrogen receptor α (ERα) and the downstream blockage of NF-κB p65 nuclear translocation. Animal studies showed that ERα selective agonist 4,4',4″-(4-propyl-[1H]-pyrazole-1,3,5-triyl) trisphenol (PPT) was able to replicate the therapeutic effects of E2 in treating osteoporotic OVX mice. Together, our findings reveal that estrogen deficiency-mediated M2 macrophage osteoclastogenesis leads to increased M1/M2 ratio in OVX mice. Reducing the M1/M2 ratio is a potential therapeutic target in treating postmenopausal osteoporosis. © 2017 American Society for Bone and Mineral Research.
Enhancement of durability of glass fiber-reinforced cement with PVA (2002)

The main thrust of this research was to determine the effectiveness of polyvinyl alcohol (PVA) powder in enhancing the durability of short GFRC materials. Accelerated aging of the materials was achieved through low-pressure steam curing in a moist chamber. The strength and ductility of GFRC were measured by the direct tension test, which showed that incorporation of PVA powder into GFRC could improve its mechanical behaviour and turn it from brittle to ductile. To investigate the mechanism of the tensile strength enhancement, the fiber-matrix interface was examined by polarizing optical microscopy and scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDAX). It was found that PVA powder tended to migrate to the fiber-matrix interfacial zone and thus prevented the accumulation of calcium hydroxide in this area. PVA film around the fiber resulted in a more ductile interfacial microstructure and better bonding between fiber and matrix, which should be responsible for enhancing the tensile property and preventing the aging of GFRC. Furthermore, PVA powder reduced the microhardness and brittleness at the interface.
Properties of Monoazo Disperse Dyes Derived from 3‐amino‐5‐nitro(2,1) benzisothiazole (1984)

Some disperse dyes based on 3‐amino‐5‐nitro(2, 1) enz‐isothiazole have been synthesised by coupling with derivatives of N‐phenyl‐β‐alanine or N‐(2‐cyano‐ethyljaniline. Spectral properties in the infra‐red and visible range of the dyes obtained were investigated. The visible spectra suggest the possibility of aggregation when the secondary amines were used as a coupling component. This probably has some influence on the intensity of the dyeings obtained. The dyes were found to have good fastness to light and dry‐heat treatment and very interesting colouristic properties.
Provision ground and plantation labour in four windward islands: Competition for resources during slavery (1991)

The role of the provision ground and internal marketing system in the context of plantation slavery has been a subject of increased interest during the last generation. A description and analysis of the provision-ground system in the four Windward Islands of Grenada, St Lucia, St Vincent and Tobago during the last 50 years of slavery offer insight into these large subjects. Three tentative conclusions are reached: first, echoing Mintz, that the provision-ground and internal marketing system provided an extensive stage, as in Jamaica, for slaves participation in independent activities; second, that the slaves attempts to exploit the potential of these activities inevitably created intense competition between themselves and plantation owners and managers for labour services and land resources; third, that slaves success in creating and defending corners of independent existence fostered the growth of attitudes to plantation labour and to independent activities which affected labour relations in the post-slavery period.
Nested Array for Antenna Deployment in Massive MIMO with Spectrum Efficiency (2016)

The nested array was firstly introduced to perform array processing with increased degrees of freedom using much fewer physical sensors In this paper, we apply nested array to antenna deployment in massive MIMO, which can tremendously reduce the number of antennas, and achieve the same performance. Besides, this deployment for massive MIMO has also spectrum efficiency. As a case study, we demonstrate that real-world LTE/LTE-A mobile service data traffic is quite fluctuating, and adaptive bandwidth allocation should be performed to increase spectrum efficiency.

간호사의 정서지능과 직무스트레스 -지방공립의료원을 중심으로- (2010)

Purpose: This study was done to identify the relationship between emotional intelligence (EI) and job stress of clinical nurses in small to medium-sized hospitals. Methods: Data were collected from a convenience sample of 152 nurses working in 4 local public hospitals in one district. EI was measured with the scale developed by Law, Wong, & Song (2004), and job stress with the scale by Choi, Kang, & Woo (2006). Data were analyzed with PASW (SPSS) 18.0, using descriptive statistics, t-test, ANOVA, Scheffe`` test, Pearson correlation coefficients, and multiple regression. Results: There were significant differences in EI according to work time, in self-emotional appraisal according to salary, in regulation of emotion according to marital status, age, work time, and salary. There were also significant differences in job stress including somatization, depression and anger according to marital status, work time, and salary. Correlation between EI and job stress was negative. EI explained 17.3% of variance in job stress. Conclusion: The findings indicate that to decrease job stress, nursing managers need to develop EI, especially self-emotional appraisal and regulation of emotion for nurses in their twenties and for unmarried nurses.

The compounds were screened for hypo/hyper glycemia activity, IR spectra of some 1-5-benzodiazepines were also studied.
Endoscopic Bladder Transection for Detrusor Instability (1987)

Eighteen patients with intractable detrusor instability were treated by endoscopic bladder transection. In two patients there was complete symptomatic relief. Two more were rendered continent but continued to complain of urgency and nocturia. The remaining 14 patients were not improved by the procedure. These results have caused us to abandon this operation as a treatment for detrusor instability.
