Design and FPGA implementation of a FMCW radar baseband processor (2012)

This paper presents a base band processor design for frequency-modulation-continuous-waveform (FMCW) radar systems, which are capable of identifying the Doppler frequency from the spectrum distance calculation. Besides the FFT computing kernel and constant false alarm rate (CFAR) signal detection module, the system is further enhanced with functions like pulse identification, clutter cancellation and frequency resolution interpolation features. A control microprocessor is employed to coordinate the operations of basic function modules in different working phases. The design meet the system specs requiring a false alarm rate P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">fa</sub> ≤ 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> , a detection rate P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> ≥ 0.95 and a distance resolution of 1m. The entire design is implemented in a Xilinx Virtex-IV FPGA.

TiNy Threads: A Thread Virtual Machine for the Cyclops64 Cellular Architecture (2005)

This paper presents the design and implementation of a thread virtual machine, called TNT (or TiNy-Threads) for the IBM Cyclops64 architecture (the latest Cyclops architecture that employs a unique multiprocessor-on-a-chip design with a very large number of hardware thread units and embedded memory) - as the cornerstone of the C64 system software. We highlight how to achieve high efficiency by mapping (and matching) the TNT thread model directly to the Cyclops ISA features assisted by a native TNT thread runtime library. Major results of our experimental study demonstrate good efficiency, scalability and usability of our TNT model/implementation.
Cloning, expression, and characterization of cDNAs encoding Arabidopsis thaliana squalene synthase. (1995)

We have isolated and characterized two overlapping cDNA clones for Arabidopsis thaliana squalene synthase. Their nucleotide sequences contained an open reading frame for a 410-amino acid polypeptide (calculated molecular mass, 47 kDa). The deduced amino acid sequence of the Arabidopsis polypeptide was significantly homologous (42-44% identical) to the sequences of known squalene synthases of several species, from yeast to man, but it was much less homologous to that of tomato phytoene synthase. To express the Arabidopsis enzyme in Escherichia coli, the entire coding region was subcloned into an expression vector. A cell-free extract of E. coli transformed with the recombinant plasmid, in the presence of NADPH and Mg2+, efficiently converted [14C]farnesyl diphosphate into squalene. On the other hand, in the absence of NADPH and the presence of Mn2+, the cell-free extract formed dehydrosqualene as a secondary product. Another E. coli extract expressing mouse squalene synthase showed the same activity as the Arabidopsis enzyme. Therefore, both the structure and reaction mechanism of squalene synthases are markedly conserved in taxonomically remote eukaryotes.

A Database Architecture and Version Control for Group Work (1994)

In order to progress team cooperative work, it is desirable that each member can not only refer to the shared resouwes, but also maintain his/her own private resources. In our previow paper, we proposed a database system in which wers could maintain private data in their own private work spaces and use the shared data in a shared work space. In this paper, we propose a data management model where private and shared versions can be bound easily. Assume that, a user creates certain data and migrates a copy of the data to the shared work space. When the creator improves the data in the shared work space, he/she often refers the private versions left an the private work space. It is important to provide the whole history of versions.
Truncation Error Evaluation Method for Minimal Cut Set-Based Fault Tree Analysis (2005)

The minimal cut set approach is extensively used in probabilistic safety assessments. Truncation neglecting low-probability cut sets is usually applied to determine the minimal cut sets of a manageable size. The errors in the calculated top event probability due to the truncation are not usually known. A truncation error evaluation method, which is based on the Monte Carlo simulation technique and the characteristics of coherent reliability systems, is proposed in this paper. This method can be easily applied to the most problems in probabilistic safety assessments and does not require much computation time. The applicability and accuracy of the proposed method are also described.
Low Temperature Oxidation of Metals and Semiconductors (1984)

The growth of oxide films on metals and semiconductors at low temperatures has been interpreted using the Cabrera‐Mott theory which assumes a uniform oxide structure. Kinetic data taken from the literature were introduced into the Ghez integration of the Cabrera‐Mott equation. Results were found to correlate with a division of oxides into network formers, intermediates, and modifiers. The network formers and intermediates were best fit by inverse logarithmic kinetics (Cabrera‐Mott), while the modifiers appeared to follow direct logarithmic kinetics. Values of activation energy for ion movement, the number of potentially mobile ions, and the self‐induced voltage across the oxide have been derived for the network forming and intermediate oxides. These values are compared with those obtained from other experiments.
Dye Tracers Define Differential Endothelial and Smooth Muscle Coupling Patterns Within the Arteriolar Wall (1995)

Dye tracers were chosen, based on net charge, chemical structure, and reactive groups, to test for the existence of and to provide novel insight into channel selectivities of junctional pathways connecting smooth muscle and endothelial cells of the arteriolar wall. Dyes were injected into individual smooth muscle or endothelial cells of hamster cheek pouch arterioles using microiontophoresis. Coupling, independent of tracer net charge, was seen both within and between cell layers. Endothelial cells were well coupled by all of the tested dyes. Smooth muscle junctions appeared less effective in dye transfer than endothelial junctions. Lucifer yellow was confirmed to be a poor tracer of smooth muscle gap junctions, and remarkably this dye and other related sulfate-containing molecules interfered with dye movement through smooth muscle but not endothelial junctions. Myoendothelial junctions showed a striking polarity of dye movement, with dye transfer from endothelial to smooth muscle cells but little or no transfer in the reverse direction. Because the dyes have size and charge characteristics similar to those of known cellular second messengers, these findings have important implications for cell-cell signaling in the vessel wall.
Fine-Grained Trust Assertions for Privacy Management in the Social Semantic Web (2013)

Social Web applications are engineered around users sharing personal information with their connected peers. They provide generic privacy settings which user specify with whom their information can be shared. However, this does not model the real world where one might trust someone with specific personal data but not with other data. Therefore, trust has to be taken into consideration when applying privacy settings. In our previous work, we modelled fine-grained privacy preferences without asserting trust. In this work, we add trust to our Privacy Preference Framework to provide more fine-grained enforcement of access control when sharing information. This ensures that users' personal information is accessed only by the intended third parties.
B7-H3, B7-H4, Foxp3 and IL-2 expression in cervical cancer: Associations with patient outcome and clinical significance (2016)

The aim of this study was to determine the expression of B7-H3, B7-H4, Foxp3 and IL-2 in cervical cancer tissues, and evaluate the corresponding clinical significance. The expression of B7-H3, B7-H4, Foxp3 and IL-2 in 108 cervical cancer specimens was detected using immunohistochemistry, and their relationship with clinicopathologic parameters was determined. B7-H3, B7-H4 and Foxp3 had high levels of expression in cervical cancer cells (72.22, 80.56, and 91.56%, respectively). B7-H3 levels were only significantly associated with tumor size (P=0.013), while B7-H4, Foxp3 and IL-2 levels were significantly associated with International Federation of Gynecology and Obstetrics (FIGO) stage (P=0.023, 0.014 and 0.036, respectively) and tumor size (P=0.045, 0.010 and 0.021, respectively). Their expression levels were not correlated with age, histologic type, differentiation and lymph node metastasis (all P>0.05). Cox regression multivariate analysis confirmed that B7-H3 or B7-H4 overexpression was an independent prognostic factor. In addition, there were significant positive relationships between the expression of B7-H3 and B7-H4 with Foxp3 (P<0.001). In contrast, the expression of B7-H3 and B7-H4 was negatively correlated with IL-2 (P<0.05). B7-H3, B7-H4 and Foxp3 may be useful biomarkers in patients with cervical cancer for predicting treatment.
A Reconfigurable Applcation Specific Instruction Set Processor for Viterbi and Log-MAP Decoding (2006)

Future mobile and wireless communications networks require flexible modem architectures with high performance. This paper presents a dynamically reconfigurable application specific instruction set processor (dr-ASIP) for the application domain of channel coding in wireless communications systems: FlexiTreP. It features Viterbi and Log-MAP decoding for support of binary convolutional codes and binary as well as duobinary turbo codes. The FlexiTreP can support more than 10 current wireless communication standards. Furthermore, its flexibility allows for adaptation to future systems. It consists of a specialized pipeline and a dedicated communication and memory infrastructure. Simulation and synthesis results obtained for Log-MAP and Viterbi applications demonstrate maximum throughput of 200 and 133 Mbps, respectively
Thermoforming: A Plastics Processing Guide (1987)

FROM THE FOREWORDDr. Gruenwald has indicated the desirable properties of polymerics for differing applications; thus, his text is especially useful for polymer chemists who must tailor plastic materials for specific groups of applications. Engineers in extruding and calendering film and sheet will benefit from the intimate relationships elucidated between processing parameters imposed upon stocks employed in thermoforming and the products thereof. Mold designers are provided with a complete guide that will enable them to avoid the less obvious pitfalls and wasted effort so often experienced in the evolution of molds for (especially) complex parts.. Quite likely, Dr. Gruenwald's suggestions willl lead to considerable benefits to those who read and practice by this remarkable exposition of thermoforming technology. Robert K.

Use of thiourea to increase the solubility of membrane proteins in two‐dimensional electrophoresis (1998)

The separation of membrane proteins by high-resolution two-dimensional electrophoresis was carried out. At high loads, these proteins are prone to precipitation, resulting in poor resolution. It is shown here that the use of thiourea, previously described for focusing in immobilized pH gradients, can be extended to conventional isoelectric focusing. As thiourea inhibits acrylamide polymerization, a modified photopolymerization system must be used. These modifications result in higher solubility of proteins during IEF, thereby increasing the resolution and capacity of the two-dimensional gels.
cis elements that contribute to geminivirus transcriptional regulation and the efficiency of DNA replication (1997)

The A genomic component of the geminivirus tomato golden mosaic virus (TGMV) contains a 5' intergenic sequence that includes the overlapping AL61 promoter and positive-strand origin of DNA replication. The TGMV AL1 protein negatively regulates its own transcription and mediates origin recognition by binding to a repeated motif shared by the AL61 promoter and the viral origin. We examined a series of truncated or mutated 5' intergenic regions in transient expression and replication assay to identify other DNA sequences that contribute to TGMV promoter and origin function. These experiments revealed that negative regulation of the AL61 promoter is complex, involving multiple cis-acting sequences and the AL1 and AL4 proteins, which acted through different DNA elements. We also found that mutation of the TATA box motif in the AL61 promoter reduced overall transcriptional activity and AL1-mediated repression, confirming the importance of this sequence in promoter function. Mutation of a G-box consensus sequence was highly detrimental to AL61 transcription and abolished AL1 sensitivity, suggesting that AL1 interferes with transcriptional activation. Cotransfection experiments showed that the TATA box and G-box motif mutations also impaired viral DNA replication in the presence of a wild-type origin but had no effect in its absence, demonstrating that these transcriptional motifs also function as replication efficiency elements.
A METHOD FOR DETERMINING THE UTILISATION OF GLUCOSE BY MYCOPLASMAS (1975)

A technique for measuring glucose utilisation by mycoplasmas, in which the disappearance of glucose is monitored by the glucose-oxidase method, is proposed as an alternative to the pH method. For maximum reliability the number of organisms in the test suspension must exceed a critical minimum value. Differences in efficiency of glucose utilisation were demonstrated between species of Mycoplasma and Acholeplasma.
Human Motion Tracking by Combining View-based and Model-based Methods for Monocular Video Sequences (2003)

사람의 동작을 믿을 수 있게 따라가는 것은 감시용 비디오나 사람과 컴퓨터간의 사용자 인터페이스 개발에 있어서 필수적이다. 이 논문은 모습 기반법(appearance-based method)과 모델 사용법을 혼용하여 사람을 추적하는 새로운 방법에 관한 논문이다. 하나의 비디오 입력이 화소 단위 및 물체 단위로 처리된다. 화소 단위의 처리에 있어서 개별 화소색을 분류하는 훈련방법으로, 가우스 혼합 모델(Gaussian mixture model)을 사용하였다. 물체 단위의 처리에 있어서 사람 몸에 대한 삼차원 모델링을 하고, 모델 몸체를 투사면(projection plane)에 투사시켰다. 투사된 몸체와 배경을 제외한 영상과 계산 기하 방법을 사용하여, 화소보다 작은 단위로 겹쳐지는 면적을 계산하였다. 우리의 방법은 정방향 기구학 (forward kinematics)을 사용하므로 역방향 기구학(inverse kinematics)을 사용하는 방법과 달리 계산 결함(singularity)을 갖지 않는다. 이 논문에서는 사람의 동작을 추적하기 위한 문제를 비선형 방정식 문제로 바꾸었다. 비선형 방정식의 비용 함수는 전경(foreground)의 영상 실루엣(silhouette)과 투사된 삼차원 모델 몸체의 실루엣의 겹쳐지는 면적이다. 화소 단위의 영상을 화소를 하나의 면적으로 계산함으로써, 겹쳐지는 면적에 대한 실수 단위의 계산은 계산 기하를 사용하였다. 이 논문의 방법은 다양한 사람 동작을 인식하기 위하여 사용되었다. 비디오에 나타나는 사람 동작 추적은 매우 우수하다. Reliable tracking of moving humans is essential to motion estimation, video surveillance and human-computer interface. This paper presents a new approach to human motion tracking that combines appearance-based and model-based techniques. Monocular color video is processed at both pixel level and object level. At the pixel level, a Gaussian mixture model is used to train and classily individual pixel colors. At the object level, a 3D human body model projected on a 2D image plane is used to fit the image data. Our method does not use inverse kinematics due to the singularity problem. While many others use stochastic sampling for model-based motion tracking, our method is purely dependent on nonlinear programming. We convert the human motion tracking problem into a nonlinear programming problem. A cost function for parameter optimization is used to estimate the degree of the overlapping between the foreground input image silhouette and a projected 3D model body silhouette. The overlapping is computed using computational geometry by converting a set of pixels from the image domain to a polygon in the real projection plane domain. Our method is used to recognize various human motions. Motion tracking results from video sequences are very encouraging.
Comparative reductions of hepatitis A virus, enteroviruses and coliphage MS2 in miniature soil columns (1995)

The reduction of viruses in wastewater and other contaminated waters in the subsurface or soil environment is an important public health consideration for land disposal of wastes and the use of ground sources as water supplies. Because of the lack of information on the comparative reductions of different viruses in soils receiving wastes, we determined the reductions of hepatitis A virus (HAV), poliovirus 1, echovirus 1 and the indicator virus MS2 in 10-cm deep, miniature soil columns dosed twice weekly with 2.5 cm of water or wastewater and incubated at 5 or 25°C for 16 weeks. The soils studied were coarse sand, loamy sand, clay loam and organic muck. By examination of column effluents, few or no viruses were detected in clay loam column effluents, with &gt;99.98% virus reductions under all conditions tested. In organic muck columns virus reductions ranged from 30-98%, with greater reductions at 25°C than at 5°C and greater reductions of enteroviruses than either HAV or MS2. In the sandy soil columns viruses were retained generally better in loamy sand than in coarse sand. Overall, poliovirus was reduced the most and echovirus the least. In coarse sand, mean virus reductions ranged from a low of about 50% for echovirus at 5° to a high of about 99.4% for poliovirus at 25°. In loamy sand, mean virus reductions ranged from a low of about 60% for echovirus at 5° to a high of 99.997% for poliovirus at 25°. Virus reductions were greater in sandy soil columns dosed with groundwater than with wastewater. The appreciable breakthroughs of viruses in column effluents of organic muck and coarse sand soils indicate that these soil types may be unsuitable for land application of wastewater under some hydrogeological conditions.
Thixotropy of Alginate Gels (1956)

Abstract Thixotropy was observed on the gels formed by the addition of the suitable amounts of cupric chloride, barium chloride, lead nitrate, calcium chloride, cadmium sulfate, zinc sulfate and nickel sulfate to the solutions of sodium alginate. The setting time of the thixotropic gels was observed to change with the amount of the electrolyte added, the ageing time of the gels, the degree of polymerization of sodium alginate used and pH of the system. The thixotropic behavior was observed to change also with the volume of the system. Furthermore, it was found that thixotropy was observed when about 25–54% of the total alginate ions combine with cupric ions, whereas the combination of more than half of the total alginate ion results in nonthixotropic gelation. The thixotropic gel could be formed also by the addition of sodium alginate to the once precipitated copper alginate.
A tunable bandpass sigma-delta A/D conversion for mobile communication receiver (2002)

A channel selective A/D convertor for mobile communication receiver using /spl Sigma//spl Delta/ modulation is presented. For input signals with different frequencies and relative small bandwidth, the bandpass /spl Sigma//spl Delta/ convertor could serve both the roles of tuning and A/D conversion at the same time. The issues of sensitivity of the parameters to the channel selection and channel error tolerance level in terms of inband noise, which are associated with the implementation of channel selective /spl Sigma//spl Delta/ A/D converter in mobile communication environment, are discussed. All the simulation and calculation are based on the simplified second order bandpass structure, and their results have given some indication to the trade-off between sensitivity and the overdesign necessary to meet the system sensitivity requirement.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Dehydrooligopeptides. XVII. Practical Syntheses of All of the Diastereomers of <i>N</i>,<i>N</i>-Protected 2,3-Diaminobutanoic Acids from <scp>l</scp>- and <scp>d</scp>-Threonine Derivatives (1995)

Abstract Syntheses of all of the diastereomers of 2,3-diaminobutanoic acids, found in some peptide antibiotics and toxins, were accomplished. The four isomers were derived mainly through two pathways including SN2 inversions of the β-substituent of l- or d-threonine derivatives. The various protecting groups and effective nucleophiles for the SN2 inversion were examined.
Healthcare professional and patient perceptions of a new prefilled insulin pen versus vial and syringe (2012)

The importance of firm quotes and rapid executions: Evidence from the January 1994 SOES rules changes (1997)

Nasdaq's Small Order Execution System (SOES) allows orders to be submitted by computer, thereby assuring rapid execution at quoted prices. We examine trading in the 20 largest Nasdaq stocks around the time of a rule change that reduced the largest SOES trades from 1000 to 500 shares. We show that SOES trades contain information about short-term price movements and that SOES trading declined dramatically with the rule change. However, quoted and effective spreads were unaffected by the rule change.
Complementary and Alternative Medicine for Major Depressive Disorder (2010)

Participants in CAM trials were more likely to be female and to have a lower placebo-response rate compared to those in standard antidepressant trials for MDD. Trials of standard antidepressants and CAM therapies were composed of patients with similar depression severity.
