An Auto-Verification Method of Security Events Based on Empirical Analysis for Advanced Security Monitoring and Response (2014)

국내 사이버공격 대응 전담조직(CERT)들은 탐지패턴 기반의 보안장비(IDS, TMS 등)를 활용하여 사이버 침해공격에 대한 탐지 대응을 수행하고 있다. 특히, 공공 연구기관의 경우 국가정보원(NIS) 내 국가사이버안전센터(NCSC)를 중심으로 30여개의 부문 보안관제 센터가 구축 운영되고 있으며, 주로 침해위협수집시스템(TMS)을 활용하여 사이버 공격에 대한 탐지 분석 대응을 수행하고 있다. 그러나 현재의 보안관제 체계에서는 대량의 보안이벤트가 보안장비에 의해 발생되고 있을 뿐만 아니라, 보안관제 요원이 보안이벤트에 대한 실제 공격여부를 판단하기 위해서는 추가적인 분석 작업을 수행해야 하므로 보안이벤트 전체에 대한 대응이 현실적으로 불가능한 실정이다. 또한 현재의 보안관제 업무는 보안관제 요원이 보유한 전문지식 및 경험에만 전적으로 의존하고 있기 때문에 특정 보안이벤트에만 분석이 집중되는 업무편중 현상이 발생하며, 이로 인해 기존에 알려지지 않은 새로운 해킹 공격기술에 대한 대응능력이 부족하다. 따라서 본 논문은 실시간 보안관제 및 침해대응 활동의 효율성을 극대화하고 대규모 해킹공격에 대한 조기대응 역량을 강화하기 위해 실제 해킹공격에 대한 실증적 분석에 기반한 대용량 보안이벤트 자동검증 방법을 제안한다. Domestic CERTs are carrying out monitoring and response against cyber attacks using security devices(e.g., IDS, TMS, etc) based on signatures. Particularly, in case of public and research institutes, about 30 security monitoring and response centers are being operated under National Cyber Security Center(NCSC) of National Intelligence Service(NIS). They are mainly using Threat Management System(TMS) for providing security monitoring and response service. Since TMS raises a large amount of security events and most of them are not related to real cyber attacks, security analyst who carries out the security monitoring and response suffers from analyzing all the TMS events and finding out real cyber attacks from them. Also, since the security monitoring and response tasks depend on security analyst's know-how, there is a fatal problem in that they tend to focus on analyzing specific security events, so that it is unable to analyze and respond unknown cyber attacks. Therefore, we propose automated verification method of security events based on their empirical analysis to improve performance of security monitoring and response.
Adapting a message-driven parallel application to GPU-accelerated clusters (2008)

Graphics processing units (GPUs) have become an attractive option for accelerating scientific computations as a result of advances in the performance and flexibility of GPU hardware, and due to the availability of GPU software development tools targeting general purpose and scientific computation. However, effective use of GPUs in clusters presents a number of application development and system integration challenges. We describe strategies for the decomposition and scheduling of computation among CPU cores and GPUs, and techniques for overlapping communication and CPU computation with GPU kernel execution. We report the adaptation of these techniques to NAMD, a widely-used parallel molecular dynamics simulation package, and present performance results for a 64-core 64-GPU cluster.
Fast Preparation of <i>W</i> States for Hot Trapped Ions (2005)

A scheme is presented for generating W states for three or four trapped ions in thermal motion. The scheme works in the regime, where the Rabi frequency of the laser field is on the order of the trap frequency, resulting a fast entanglement speed, which is of importance in view of decoherence.
Myelin/oligodendrocyte glycoprotein (MOG) expression is associated with myelin deposition (1996)

We investigated the onset of expression of the myelin/oligodendrocyte glycoprotein (MOG) mRNA and protein in the developing mouse central nervous system. In situ hybridization on brain sections at different stages of embryonic and postnatal development showed that MOG transcripts were first detected at birth in the medulla oblongata. During the first week after birth, cells expressing MOG mRNA were located in the ventral longitudinal funiculus. During the second postnatal week, the pattern of MOG mRNA expression extended rostrally to the mid-forebrain regions and reached completion by the beginning of the third week. MOG transcription was delayed by several days with respect to myelin basic protein (MBP), and it appeared that while the MBP probe labeled both non-myelinating and myelinating oligodendrocytes, only the latter were MOG-positive. In vitro, immunocytochemical analysis of MOG protein expression, performed on myelinating cultures derived from mouse brain embryos at 15 days of gestation, confirmed the strict restriction of MOG expression to myelinating oligodendrocytes. In particular, oligodendrocytes lining up their processes along axons, but not yet having started to deposit a myelin sheath, were still MOG negative. However, in the same cultures, pseudo-myelinating oligodendrocytes (i.e., cells not associated with neurites, but forming whorls of myelin-like figures) were MOG positive. Similarly, rat CG4 cells, an oligodendrocyte-like cell line, expressed MOG only after they had extended sheet-like processes, which suggested that the activation of MOG transcription depends more on an intrinsic oligodendroglial maturation program of myelination than on a neuronal signal.
Identification of a Copper-Responsive Two-Component System on the Chromosome of <i>Escherichia coli</i> K-12 (2000)

Using a genetic screen we have identified two chromosomal genes, cusRS (ylcA ybcZ), from Escherichia coli K-12 that encode a two-component, signal transduction system that is responsive to copper ions. This regulatory system is required for copper-induced expression of pcoE, a plasmid-borne gene from the E. coli copper resistance operon pco. The closest homologs of CusR and CusS are plasmid-borne two-component systems that are also involved in metal responsive gene regulation: PcoR and PcoS from the pco operon of E. coli; CopR and CopS from the cop operon, which provides copper resistance to Pseudomonas syringae; and SilR and SilS from the sil locus, which provides silver ion resistance to Salmonella enterica serovar Typhimurium. The genes cusRS are also required for the copper-dependent expression of at least one chromosomal gene, designated cusC (ylcB), which is allelic to the recently identified virulence gene ibeB in E. coli K1. The cus locus may comprise a copper ion efflux system, because the expression of cusC is induced by high concentrations of copper ions. Furthermore, the translation products of cusC and additional downstream genes are homologous to known metal ion antiporters.
The Effect of TEOS/MTES Ratio on the Structural and Dielectric Properties of Porous Silica Films (2003)

This paper presents the results of the characterization of porous silica films used as intermetal dielectrics. The films were fabricated via sol-gel process using tetraethyl orthosilicate (TEOS) and methyltriethoxysilane (MTES) as precursors with acid and base as catalysts. Several advanced techniques such as transmission electron microscopy, specular X-ray reflectivity, Fourier transform infrared spectroscopy, nitrogen adsorption, thermal gravimetric, and differential thermal analysis have been employed to obtain information on the structural properties of the films and reaction mechanisms involved in the sol-gel process of such dielectrics. The characterization results show the effects of the TEOS/MTES ratio on the development of the porosity, pore size, and pore interconnectivity of the films, which reflects the influence of different mechanisms of hydrolysis and condensation of silica precursors in different pH conditions and the existence of covalently bonded organic ligands on the pore structure. An inherently low dielectric constant of around 2.0 was realized for about 60% porosity in the silica films. The pore sizes were less than 10 nm with majority of pores being closed-cells. © 2003 The Electrochemical Society. All rights reserved.
Device Circuit Co-Design Issues in Vertical Nanowire CMOS Platform (2012)

In this letter, we investigate the effect of device and layout parasitics on circuit performance of vertical nanowire (VNW) CMOS technology. We evaluate the effect of source-drain extension ( <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">S</i> / <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">D</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ext</sub> ) scaling and device asymmetry on device and circuit performances for 15 nm VNW CMOS. It is seen that, due to reduced series resistance, circuit delay continues to improve with <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">S</i> / <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">D</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ext</sub> down to 10 nm, despite increased parasitic capacitances. Also, we show that asymmetry between top and bottom electrodes plays a strong role in determining circuit delay, while layout-dependent parasitics are of secondary importance. The results show that delay is increased by 65% with top electrode as source, which is attributed to increase in series resistance and gate-drain overlap capacitances. The comparison of VNW and FinFET CMOS shows nearly 40% delay reduction, highlighting excellent potential of VNW CMOS for 15 nm and below technology nodes.
Guidelines for statistically based sampling reduction (2002)

Presented are general guidelines, with examples, for sample reduction and monitor elimination in a high-volume manufacturing environment. Although statistical soundness is never overlooked, this focus on sampling is from a practical point of view. That is, can we have this level of sampling indefinitely and still run a profitable operation? Examples are taken from a factory where comprehensive sample reduction has led to substantial cost savings.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Thin film memories (1959)

THE STORAGE ELEMENTS in thin film memories are deposited magnetic nickel-iron films, 2000Å thick. The films show a direction of preferred magnetization (Figure 1) chosen to be at a 30 ° angle to the drive conductor. Each film can be compared with a magnetic dipole having two stable states N and P.
Inheritance of the shared epitope and long‐term outcomes of rheumatoid arthritis among community‐based Caucasian females (1998)

Multiple HLA-DRB1 alleles encoding a shared epitope (SE) at amino acid positions 70–74 are associated with susceptibility and severity of rheumatoid arthritis (RA). We examined the relationship between the number and DRB1 genotype of SE alleles inherited and long-term outcomes of 180 community-based, Caucasian female RA patients followed annually for up to 12 years. Outcomes examined were physician assessment of RA course; annual measures of pain, function, and number of painful joint groups; history of joint surgery; and resource utilization. Models accounted for correlation among serial observations for the same patient and adjusted for patient age and disease stage. We examined two genetic models: a SE model in which patients were classified according to the number of SE copies inherited and a genotype model in which patients were categorized into one of six groups based on the inherited DRB1 genotype. We used likelihood ratio tests to compare these genetic models and to compare alternative model specifications. Our results demonstrate strong associations between inheritance of the SE and long-term outcomes of community-based Caucasian females with RA. However, the pattern of results is not consistent across the outcomes. An additive model of risk is apparent for history of joint surgery and RA hospitalization. In contrast, a near reversal of this pattern is apparent for function, joint pain, pain rating, and RA physician visits. Finally, although the genotype model did not appear to be a better predictive model for RA outcomes overall, it did reveal some striking heterogeneity of SE alleles that was masked by the more parsimonious SE model. For example, the odds ratio (OR) for joint surgery for patients with 2 SE copies (OR = 3.16) reflects an average of 2 very different ORs when patients are further categorized according to genotype groups 4 and 5 (OR = 1.3 and 11.9, respectively).

Meningeal Carcinomatosis (1981)

We reviewed 33 cases of meningeal carcinomatosis seen at the Mount Sinai Hospital, New York, from 1970 through 1979. The major sources of meningeal disease were carcinoma of the breast (21 cases), carcinoma of the lung (five), and malignant melanoma (five). Seventy-eight percent of the patients had widespread metastases at the time of neurologic diagnosis. A combination of radiotherapy and intrathecal administration of methotrexate was the most successful treatment, and 14 of 22 treated patients showed at least symptomatic improvement; however, mean survival in the most improved group was still less than six months.
Prevalence of carbapenem resistant bacterial strains isolated from different clinical samples: study from a tertiary care hospital in Kathmandu, Nepal (2017)

Background Carbapenems are considered as drugs of choice for the treatment of the infections caused by drug resistant bacteria. However, in the recent years the prevalence of carbapenem resistant gram negative bacteria has increased significantly. The main objective of this study was to determine the prevalence of carbapenemase producing gram negative bacteria among all the clinical isolates.Material and methods A total of 3246 non-repeated, different clinical specimens from patients attending Kathmandu Model Hospital, from July 2013 to January 2014 were cultured and the gram negative bacterial isolates obtained were subjected to identification with the help of colony morphology, Gram’s stain and conventional biochemical tests. Kirby-Bauer disk diffusion technique was used to perform antimicrobial susceptibility testing. Phenotypic confirmation of carbapenemase and AmpC beta-lactamase production was done by combined disc method.Results 890 samples showed the growth of bacterial pathogens. Out of total 769 gram negative bacteria, 57 were found to be carbapenem resistant. Of which, highest number (47) of the isolates were found to be metallo-β lactamase (MBL) producers. Six bacterial isolates produced both (Klebsiella pneumoniae carbapenemase) KPC and MBL, whereas only one isolate was found to be positive for both MBL and AmpC. Three bacterial strains showed carbapenem resistance due to over production of AmpC β-lactamase.Conclusion Among carbapenem resistant gram negative bacteria, MBL was present as the major enzyme responsible for resisting carbapenem antibiotics.
Obstacle recognition using region-based color segmentation techniques for mobile robot navigation (2006)

This work has been performed in conjunction with the ECE Department's autonomous vehicle entry in the 2006 Intelligent Ground Vehicle Competition (www.igvc.org). The course to be traversed in the competition consists of a lane demarcated by paint lines on grass along with other challenging artifacts such as a sandpit, a ramp, potholes, colored tarps, and obstacles set up using orange and white construction barrels. In this paper an enhanced obstacle detection and mapping algorithm based on region-based color segmentation techniques is described. The main purpose of this algorithm is to detect obstacles which are not properly identified by the LADAR (Laser Detection and Ranging) system optimally mounted close to the ground, due to "shadowing" occasionally resulting in bad navigation decisions. On the other hand, the camera that is primarily used to detect the lane lines is mounted at 6 feet. In this work we concentrate on the identification of orange/red construction barrels. This paper proposes a generalized color segmentation technique which is potentially more versatile and faster than traditional full or partial color segmentation approaches. The developed algorithm identifies the shadowed items within the camera's field of vision and uses this to complement the LADAR information, thus facilitating an enhanced navigation strategy. The identification of barrels also aids in deleting bright objects from images which contain lane lines, which improves lane line identification.

An efficient siRNA‐mediated gene silencing in primary human monocytes, dendritic cells and macrophages (2014)

Mononuclear phagocytes (MP) comprise monocytes, macrophages (MΦ) and dendritic cells (DC), including their lineage-committed progenitors, which together have an eminent role in health and disease. Lipid-based siRNA-mediated gene inactivation is an established approach to investigate gene function in MP cells. However, although there are few protocols dedicated for siRNA-mediated gene inactivation in primary human DC and MΦ, there are none available for primary human monocytes. Moreover, there is no available method to perform comparative studies of a siRNA-mediated gene silencing in primary monocytes and other MP cells. Here, we describe a protocol optimized for the lipid-based delivery of siRNA to perform gene silencing in primary human blood monocytes, which is applicable to DCs, and differs from the classical route of siRNA delivery into MΦs. Along with this protocol, we provide a comparative analysis of how monocytes, DC and MΦ are efficiently transfected with the target siRNA without affecting cell viability, resulting in strong gene knockdown efficiency, including the simultaneous inactivation of two genes. Moreover, siRNA delivery does not affect classical functions in MP such as differentiation, phagocytosis and migration, demonstrating that this protocol does not induce non-specific major alterations in these cells. As a proof-of-principle, a functional analysis of hematopoietic cell kinase (Hck) shows for the first time that this kinase regulates the protease-dependent migration mode in human monocytes. Collectively, this protocol enables efficient gene inactivation in primary MP, suggesting a wide spectrum of applications such as siRNA-based high-throughput screening, which could ultimately improve our knowledge about MP biology.
The Deployment Pipeline (2012)

The ultimate goal of a software development process is the deployment of a quality piece of software. A deployment pipeline includes many aspects of software development that are rarely focused on by a development team. The proper development process should include as little manual testing and configuration as possible, while still confirming all of the functional and non-functional requirements that the system must satisfy. The business users, who are the most knowledgeable about the functional and non-functional requirements, also need to be directly involved in writing those tests. All dependencies should be known and managed consistently, with the objective of having a releasable application after every commit. This provides for a stable application, reliable development and production environments, consistent releases, and a product that meets a larger number of business goals.
Context learning can improve user interaction (2005)

Current computer applications lack user context and do not learn to use this context to improve user interaction. In this paper we present Sycophant, a context learning calendar application program which learns a mapping from user-related contextual features to application actions. In this preliminary work, Sycophant achieves good accuracy in learning this mapping. In addition, we find that including external context such as the presence or absence of motion and speech provides better performance in learning accurate mappings.
PIEZOCONE PENETRATION TESTING IN ATLANTIC PIEDMONT RESIDUUM: DISCUSSION AND CLOSURE (2002)

A discussion of an earlier paper with the aforementioned title by K.A. Finke, P.W. Mayne, et al., published in this journal (Volume 127, Number 1, January 2001), is given. The discusser commends the authors for using a dual-element piezocone penetrometer in their research in order to determine soil properties and pore pressure distribution around the cone. The discussion focuses on reported results of piezocone soundings, performed by the authors at the Opelika test site in the Piedmont residuum, which consists of silts/clayey silts and clayey fine sands. Closure from the authors is also provided.
Development of an ELISA for Autoantibodies to Prothrombin Showing their Prevalence in Patients with Lupus Anticoagulants (1995)

Some lupus anticoagulants (LA) have been shown to be directed against phospholipid-bound prothrombin. While developing an ELISA to detect anti-prothrombin autoantibodies in patient serum or plasma, no or very low signal was observed using human prothrombin immobilized on plain polystyrene plates. In contrast, the same LA-positive samples bound specifically to prothrombin coated on gamma-irradiated plates, depending on the radiation dose, in the absence of added calcium and phospholipid. Optimization of the assay required the addition of 0.1% Tween 20 to the buffers. Antibody specificity for immobilized prothrombin was ascertained by competition using liposome-bound prothrombin, since fluid-phase prothrombin competed poorly. Seventy-seven of 139 patients (55.4%) with LA related to a variety of underlying diseases possessed anti-prothrombin antibodies (27 IgG, 35 IgM and 15 both isotypes), either isolated or more often associated with anti-beta 2 glycoprotein I (beta 2GPI) antibodies. These included 67-71% of the patients with systemic lupus erythematosus and related disorders, primary antiphospholipid antibody syndrome or drug-induced LA (autoimmune groups), but only 19-20% of those with infection or malignancy (p < 0.001). As previously shown for anti-beta 2GPI antibodies, IgG2 was the predominant IgG subclass reactive with prothrombin. Thus, autoimmune patients with LA have a high incidence of antibodies to beta 2GPI and prothrombin, the binding of which could similarly require high antigen density and/or exposure of cryptic epitopes resulting from protein interaction with an irradiated (i.e. more anionic) polystyrene surface.
