Design and Fabrication of Diplexer using Lumped Elements (2012)

In this study, the diplexer used a separator or a combine of signals was designed and its characteristics were investigated. The diplexer consists of two fixed tuned bandpass filter such as low pass filter(LPF) and high pass filter(HPF) sharing a common part and was simulated. The diplexer with micro-strip structure was fabricated. The LPF of diplexer has insertion loss of -0.4 dB, return loss of -30 dB and 1.6 GHz cut-off frequency and HPF has insertion loss of -0.8 dB, return loss of -30 dB and 1.9 GHz cut-off frequency, respectively.
Semantic segmentation guided feature point classification and seam fusion for image stitching (2021)

Image stitching can be employed to stitch images taken from different times, perspectives, or devices into a panorama with a wider view. However, the imaging specification of images to be stitched is strict. If the imaging specification is not satisfied, artefacts caused by inaccurate alignment and unnatural distortion will occur. Semantic segmentation can solve the classification problem at the pixel level; however, image stitching significantly depends on the accuracy of feature points. Therefore, this paper proposes an image stitching algorithm based on semantic segmentation to guide feature point classification and seam fusion. First, the images are recognized by a cascade semantic segmentation network, and the image feature points are classified. Thereafter, the corresponding homography transformations are calculated using different class feature points, and the best homography mapping for the entire target image is selected. Finally, a seam-cutting algorithm based on semantic segmentation is used to compute the seam, and a feathering Poisson fusion with distance transformation is used to eliminate artefacts and light differences. Experiments show that the algorithm can generate transitional natural and perceptual stitching results even under the influence of perspective and light differences.

An Empirical Evaluation of NVM Express SSD (2015)

Emerging Non-Volatile Memory (NVM) technology with high throughput and scalability has considerable attraction in cloud and enterprise storage systems. The industry and academic communities made the NVMe specification to elicit the highest performance on NVM devices. While the technology is commercially viable, it is important to consider the performance of NVM devices with NVMe specification according to different I/O configurations and analyze workloads on the storage to exploit better performance. This paper presents the features and results of our performance study on a recent NVM express solid state drive (NVMe SSD) developed by Samsung electronics. It is a flash-based PCIe attached SSD built to follow NVMe specification. The maximum throughput is 2.5GB/s and 800MB/s for reading and writing 4KB, respectively. We analyze the performance of NVMe SSD in terms of different performance metrics with microbenchmarks and database workloads.
Alloys, Shape Memory (2006)

Abstract A shape memory alloy is a metallic substance that has a memory for shape combined with superelasticity. The mechanisms of a nickel‐titanium alloy’s shape memory effect and superelasticity are described based on thermally induced or stress induced martensite phase transformations. The thermomechanical characteristics, corrosion properties, and biocompatibility of Ni‐Ti shape memory alloys are reviewed for the design of shape memory devices. Manufacturing methods, including refining, processing, shape memory programming, and transformation temperature range measuring methods are summarized for practical applications. Finally, some applications in medical devices are reviewed as examples of current trends in the use of shape memory alloys.
Evaluation of 172 candidate polymorphisms for association with oligozoospermia or azoospermia in a large cohort of men of European descent (2010)

The associations reported in this study are promising, but much larger genome-wide studies will be necessary to confidently validate these SNPs and identify novel SNPs associated with male infertility.
Catecholaminergic polymorphic ventricular tachycardia: RYR2 mutations, bradycardia, and follow up of the patients (2005)

CPVT patients with RYR2 mutation have bradycardia regardless of the site of the mutation, which could direct molecular diagnosis in (young) patients without structural heart disease presenting with syncopal events and a slow heart rate but with normal QTc at resting ECG. Treatment with beta blockers has been very effective in our CPVT patients during initial or short term follow up. Given the risk of sudden death and the efficacy of beta blocker therapy, the identification of large numbers of RYR2 mutations thus calls for genetic screening, early diagnosis, and subsequent preventive strategies.
Evidence That the v- <i>sis</i> Gene Product Transforms by Interaction with the Receptor for Platelet-Derived Growth Factor (1985)

A scheme for partial purification of biologically active v-sis-coded protein from cells transformed with simian sarcoma virus (SSV) has made possible a functional comparison of the transforming protein with platelet-derived growth factor (PDGF). The SSV-transforming gene product is capable of specifically binding PDGF receptors, stimulating tyrosine phosphorylation of PDGF receptors, and inducing DNA synthesis in quiescent fibroblasts. Each of these activities was specifically inhibited by antibodies to different regions of the v-sis gene product. Moreover, viral infection of a variety of cell types revealed a strict correlation between those cells possessing PDGF receptors and those susceptible to transformation by SSV. These findings provide evidence that SSV-transforming activity is mediated by the interaction of a virus-coded mitogen with PDGF receptors.
Iterative Soft Decoding of Reed–Solomon Codes (2004)

This letter presents an iterative decoding method for Reed-Solomon (RS) codes. The proposed algorithm is a stochastic shifting based iterative decoding (SSID) algorithm which takes advantage of the cyclic structure of RS codes. The performances of different updating schemes are compared. Simulation results show that this method provides significant gain over hard decision decoding and is superior to some other popular soft decision methods for short RS codes.
An Group-based Security Protocol for Machine Type Communications in LTE-Advanced (2013)

사람이 개입할 필요 없이 기기 및 사물들을 셀룰러 망(cellular network)으로 연결하여 언제 어디서나 다양한 서비스를 제공하는 MTC(Machine Type Communications)는 차세대 통신의 주요 이슈로 고려되고 있다. 현재, 다수의 MTC 단말들이 동시적으로 망에 접속하려고 하면 각 MTC 단말들은 독립적인 접근 인증 절차를 수행해야 된다. 이로 인해 LTE-Advanced 네트워크에서 인증 시그널링(authentication signaling) 혼잡(congestion)과 부하(overload)의 문제가 야기된다. 본 논문은 그룹 기반의 인증 프로토콜과 키 관리 프로토콜을 제안한다. 그룹 단위로 MTC 단말들을 관리하기 위해 제안하는 프로토콜은 그룹 리더(leader)를 선출하고, 리더만이 코어 망(core network)과의 인증에 참여한다. 인증이 완료된 후, 그룹 리더는 이진트리(binary tree)를 구성하여 나머지 구성원(member)들과 MME(Mobility Management Entity)를 관리한다. 마지막으로 제안 프로토콜 분석은 제안하는 프로토콜이 MTC 단말들과 코어 망 사이에서 발생되는 인증 시그널링을 줄여줄 수 있을 뿐만 아니라 효율적으로 MTC 단말들을 관리할 수 있음도 보여준다. MTC(Machine Type Communications), providing a variety of services anytime and anywhere by connecting the cellular network to the machine and things without human intervention, is being considered as a major challenge of the next-generation communications. Currently, When a massive MTC devices simultaneously connect to the network, each MTC device needs an independent access authentication process. Because of this process, authentication signaling congestion and overload problems will cause in LTE-Advanced. In this paper, we propose a group-based authentication protocol and a key management protocol. For managing the MTC devices as group units, the proposed protocol elects a group leader and authentications only once with the core network. After the authentication is completed, a group leader manages the rest members and MME(Mobility Management Entity) by constructing a binary tree. Finally, the propose protocol analysis show that the proposed protocol not only can reduces the authentication signaling which generated in between the MTC devices and the core network but also can manages the MTC devices, efficiently.
Increased Expression of the NK Cell Receptor KLRG1 by Virus-Specific CD8 T Cells during Persistent Antigen Stimulation (2005)

The killer cell lectin-like receptor G1 (KLRG1) is a natural killer cell receptor expressed by T cells that exhibit impaired proliferative capacity. Here, we determined the KLRG1 expression by virus-specific T cells. We found that repetitive and persistent antigen stimulation leads to an increase in KLRG1 expression of virus-specific CD8+ T cells in mice and that virus-specific CD8+ T cells are mostly KLRG1+ in chronic human viral infections (human immunodeficiency virus, cytomegalovirus, and Epstein-Barr virus) but not in resolved infection (influenza virus). Thus, by using KLRG1 as a T-cell marker, our results suggest that the differentiation status and function of virus-specific CD8+ T cells are directly influenced by persistent antigen stimulation.

Improving endurance of autonomous aerial vehicles through intelligent service-station placement (2012)

A limitation of small-scale, autonomous, vertical take-off and landing (VTOL) vehicles is their relatively short flight time. This hinders their broad applicability for many commercial applications. In previous work, we present the design and implementation of ISLANDS, an autonomous self-leveling landing platform for VTOL vehicles, along with an initial approach to their placement in the field of work. In this paper, we present several new approaches for improved station placement in a field of work of arbitrary shape and size, given sensor characteristics and the nature of the application. We present these algorithms in the context of a generic survey application, but they generalize to many other applications such as search and rescue, traffic monitoring, and environment monitoring.
Analysis of head movement when viewing a wide-viewing-angle display (2015)

We assumed that both viewing distance and position would be affected by the distribution of when a person viewed a high-definition image from a short distance. We measured subjects' gaze movements as they viewed an image from two viewing distances 0.75H (51cm; H is the display height), and 1.5H (102cm), as well as from three viewing positions (center, right and left). Results revealed that while there was little difference in the location of mean gazing point, it tended to gather around the display center at every viewing distance and viewing location. This tendency was indicated by the amount of head rotation, 0.75H. Although this was larger than 1.5H, when we analyzed head movement components against gaze movement components, the difference was small. It was suggested that eye movement alone resolved the enlargement of visual field caused by short-distance viewing.

Pre-existing Immunity and Passive Immunity to Adenovirus 5 Prevents Toxicity Caused by an Oncolytic Adenovirus Vector in the Syrian Hamster Model (2009)

We have used Syrian hamsters to examine the role of pre-existing immunity to adenovirus (Ad) 5 in the toxicity of the oncolytic Ad vector INGN 007. Groups of hamsters were or were not immunized with Ad5. Half the hamsters were immunosuppressed using cyclophosphamide (CP), then injected intravenously (i.v.) with 3x the maximum tolerated dose (MTD) of INGN 007 (in immunocompetent hamsters), and toxicity and vector replication in the liver were quantitated. In nonimmunized immunocompetent hamsters, toxicity was observed early but the hamsters recovered by day 6 after vector injection. In nonimmunized immunosuppressed hamsters, the vector was lethal by 3 days. Pre-existing neutralizing antibody (NAb) prevented liver infection and hepatotoxicity in both immunocompetent and immunosuppressed hamsters. In another study, passive immunization of immunosuppressed hamsters 1 day before a lethal dose (1x MTD) of INGN 007 prevented liver infection and replication, but immunization 1 day after vector administration was barely effective. When immunosuppressed hamsters were passively immunized 1 day after injection of 1/3rd the MTD of INGN 007, then significant protection was observed against liver infection and toxicity. Therefore, serum NAb are sufficient to prevent oncolytic Ad vector liver infection and toxicity. We saw no evidence that pre-existing immunity was associated with increased vector toxicity.
Field measurement of the electroseismic response (1975)

Abstract The electroseismic response is a change in apparent resistivity induced by seismic excitation. It can be measured under field conditions with a conventional Wenner array and an explosive seismic source. In coastal plain sedimentary rocks near Gordon, Georgia, a Wenner array with 9-m electrode spacing measured a change in voltage of 100 to 300 mu v per mm/sec of 15 hz vertical particle velocity at the surface. The response correlates best with the Rayleigh surface waves and compressional body waves. By assuming a layered medium which is excited uniformly by a seismic disturbance, we can use a Taylor series expansion of the voltage expression for a Wenner array in terms of layer resistivities to obtain estimates of the perturbations of the resistivities in the layers.
Arthrography and computed arthrotomography study of seventy patients with primary glenohumeral osteoarthritis. (1995)

Seventy patients with primary glenohumeral osteoarthritis underwent roentgenographic and computed tomography studies. Glenohumeral joint space loss and a normal acromiohumeral space were the roentgenographic inclusion criteria. Women made up 61% of the sample. The dominant shoulder was affected in 95% of cases and both shoulders in 41%. Mean age at first evaluation was 65 years. Arthrography showed a tear confined to the supraspinatus tendon in 16 cases (23%); no patients had tears involving more than one tendon. Computed tomography demonstrated glenoid retroversion (mean 16 degrees) but was unable to differentiate primary glenoid dysplasia from wear due to osteoarthritis. Posterior subluxation of the humeral head was found in 28 cases (40%) but was not consistently correlated with the presence of glenoid retroversion.
Interstitial ultrasound applicators with internal cooling for controlled high temperature thermal therapy (2002)

The use of internally-cooled, direct-coupled interstitial ultrasound applicators as a means of providing controlled and directed high temperature thermal therapy was investigated. Prototype applicators were constructed using tubular ultrasound sources (1.5-2.5 mm OD) with transducers sectored for 90/spl deg/, 200/spl deg/, and 360/spl deg/ active acoustic zones. Effective cooling of the transducer surface was accomplished by the internal flow of chilled air or an integrated water mechanism. Thermal performance of the applicators was characterized through high temperature heating trials in-vivo (porcine thigh muscle and liver) and in-vitro (bovine liver) with varied sonication time and power. In general, internal cooling provided greatly enhanced thermal penetration and improved control of directional heating. This demonstrated ability to control and direct the extent of thermal coagulation shows great potential for treatment of localized tumors in sites such as prostate, brain, and liver.
<title>Optimal subpixel-level IR frame-to-frame registration</title> (1991)

Current image registration approaches tend to operate independently on each of the frames of data that are to be registered, significantly degrading performance. In this approach, however, all the frames are matched simultaneously to a reference frame, thus utilizing in a global manner the information contained in all of them. It is shown that this approach, optimal in the minimum-variance sense, provides important registration gains over current procedures.
DPPTAM: Dense piecewise planar tracking and mapping from a monocular sequence (2015)

This paper proposes a direct monocular SLAM algorithm that estimates a dense reconstruction of a scene in real-time on a CPU. Highly textured image areas are mapped using standard direct mapping techniques [1], that minimize the photometric error across different views. We make the assumption that homogeneous-color regions belong to approximately planar areas. Our contribution is a new algorithm for the estimation of such planar areas, based on the information of a superpixel segmentation and the semidense map from highly textured areas. We compare our approach against several alternatives using the public TUM dataset [2] and additional live experiments with a hand-held camera. We demonstrate that our proposal for piecewise planar monocular SLAM is faster, more accurate and more robust than the piecewise planar baseline [3]. In addition, our experimental results show how the depth regularization of monocular maps can damage its accuracy, being the piecewise planar assumption a reasonable option in indoor scenarios.
[Changes in the transcription activity of c-myc genes and heat shock proteins (HSP 70) after incubation of mouse plasmacytoma cells with dexamethasone]. (1990)

The transcription of genes c-myc and hsp70 following inhibition of plasmacytoma cells proliferation by glucocorticoid hormone dexamethasone has been investigated. The dynamics of [3H] thymidine incorporation into the plasmacytoma cells DNA after incubation with dexamethasone has been studied. It declines after 8-35 h incubation with dexamethasone. The transcriptional activity of c-myc gene decreased after 3-12 h of incubation with hormone and restored to the original level at 24-30 h. The level of transcription of hsp 70 gene decreased after 12-48 h of introduction of hormone. Heat-shock treatment resulted in decrease of c-myc expression and to some increase of the transcription of hsp 70 gene. So, the dynamics of transcriptional activity of the genes c-myc and hsp70 are different and independent.

An analysis of the Cray-1 computer (1978)

The Cray-1 is an extremely high-speed computer, intended to be used for large floating-point scientific computations. However, it is a well-balanced machine that can gracefully be used on a wide class of problems. The machine has two major architectural innovations: (1) 128 backup registers which represent a new layer in the memory hierarchy, essentially a programmer or compiler-managed cache, and (2) 8 vector registers holding up to 64 words each, and operated on by vector instructions. In this paper, we will describe the entire machine, discuss efficient ways to use the 656+ programmer-accessible registers, and discuss some of the design shortcomings.
Glassy Liquid-Crystal Films with Opposite Chirality as High-Performance Optical Notch Filters and Reflectors (2000)

Glass-forming liquid crystals combine the ability of liquid crystals to self-organize and that of polymers to undergo glass transition (instead of crystallization) upon cooling. Here is reported the synthesis and implementation of novel right- and left-handed chiral-nematic glass-forming liquid crystals in optical notch filters and reflectors, which have various applications in liquid-crystal displays. The observed attenuation of incident unpolarized light in 3.7 optical density units is the highest ever accomplished with organic and polymeric materials.
