Design considerations, simulation and experimental results and layout of the power supply are presented. The power supply meets the design specifications over a reasonable span of input voltage and output load variations.
Visualization of Earthquake Trend Information from MuST Corpus (2007)

A system for extracting and visualizing trend information about earthquakes from tagged corpus, which is distributed by a Workshop on Multimodal Summarization for Trend Information (MuST), is proposed. The topic of earthquakes does not contain only temporal trends, which are main concerns of typical topics such as gas price and stock price movement, but also spatial trends including the seismicity of earthquakes. The proposed system employs the map of Japan for visualizing spatial trends, as well as bar and line charts for temporal trends. The system also focuses on swarm earthquakes, which are visualized with the combination of the map and bar chart visualizations. Furthermore, the system provides users with an interactive facility so that they can obtain several visualization results with intuitive operations such as mouse-click on the map. A prototype system is implemented, of which functionality is compared with existing earthquake database system. The merit of extracting earthquake trend information from newspaper articles is also considered.
Testable design and support tool for cell based test (2002)

The authors describe a testable design method and the corresponding support tool for testing large-scale cells embedded on LSIs. The testable design method requires very little extra hardware to increase testability. The support tool enables users to test the large-scale cells by using already prepared test patterns. Consequently, test generation, and fault simulation times are decreased.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Self-Configuring TDMA Protocols for Enhancing Vehicle Safety With DSRC Based Vehicle-to-Vehicle Communications (2007)

This paper presents a novel Medium Access Control protocol for inter-vehicular wireless networking using the emerging Dedicated Short Range Communication (DSRC) standards. The main contribution of the paper is the design of a self- configuring TDMA protocol capable of inter-vehicle message delivery with short and deterministic delay bounds. The proposed Vehicular Self-Organizing MAC (VeSOMAC) is designed to be vehicle location and movement aware so that the MAC slots in a vehicle platoon can be time ordered based on the vehicles' relative locations for minimizing the multi-hop delivery delay. A novel feature of VeSOMAC is its in-band control mechanism for exchanging TDMA slot information during distributed MAC scheduling. It is shown that by avoiding explicit timing information exchange, VeSOMAC can work without inter-vehicle time synchronization. The in-band control mechanism is also used for fast protocol convergence during initial network setup and topology changes due to vehicle movements. A simulation model has been developed for comparing VeSOMAC's performance with that of DSRC-recommended 802.11 MAC protocol for highway traffic safety applications.

Neue Cyclosporine aus <i>Tolypocladium inflatum</i>. Die Cyclosporine K–Z (1987)

Novel Cyclosporins from Tolypocladium inflatum . The Cyclosporins K–Z The fungus T. inflatum produces a plethora of oligopeptides, the cyclosporins, which exhibit remarkable biological activities. Cyclosporin A, the main metabolite, represents a potent immunosuppressant which opened new ways in the immunotherapy of bone marrow and organ transplantations. In addition to the already described cyclosporins A–I, we report now the isolation of the cyclosporins K–Z. The structural assignments of these novel congeners are based on chemical degradation, correlation reactions, mass spectra, and extensive analysis of 1 H‐ and 13 C‐NMR spectra. All cyclosporins are cyclic undecapeptides differing from each other by minor variations in the amino‐acid sequence. Comparison of the immunosuppressive and antifungal effects furnished new information concerning structure‐activity relationships.
Biochemical markers of bone turnover – uses and limitations (2014)

Bone turnover markers of resorption and formation are released during the process of bone remodelling. These markers have been extensively studied in a number of therapeutic trials of osteoporosis during the past decade. This has led to better understanding of their physiology, clinical applications and possible ways to optimize analytical techniques. Bone markers can complement the results of bone mineral density in the management of osteoporosis, but their use in clinical practice is challenged by pre-analytical and analytical variability. This review will discuss different types of bone markers, their limitations, use in different metabolic bone diseases and current recommendations from the International Osteoporosis Foundation and the International Federation of Clinical Chemistry and Laboratory Medicine bone marker standards working group.
Rapid charger for high repetition rate pulse generator (2004)

The design and operation of a command resonant charger feeding a high repetition rate pulse generator using an advanced pseudospark device is presented. An application - corona assisted flame ignition and combustion - is discussed briefly. This application requires operation of the pseudospark switch at 30 kV charging voltage and 1 kHz repetition rate. The charging time of the 6 nF / 30 kV quasi Blumlein pulse forming circuit capacitance is 50 /spl mu/s. Operation is burst mode, with maximum 100 pulses per burst.
Ba3Ga2N4 (1996)

The crystal structure of barium gallium nitride is based on a distorted cubic close packing of N atoms with three-quarters of the octa­hedral holes occupied by Ba atoms and one-quarter of the tetrahedral holes occupied by Ga atoms. The GaN4 tetrahedra share edges and form [GaN4/23−] chains which are isosteric to edge-sharing SiS2 tetra­hedra in the SiS2 structure.
Sharing sensitive information with privacy (2011)

Modern society is increasingly dependent on (and fearful of) massive amounts and availability of electronic information. There are numerous everyday scenarios where sensitive data must be — sometimes reluctantly or suspiciously — shared between entities without mutual trust. This prompts the need for mechanisms to enable limited (privacy-preserving) information sharing. A typical scenario involves two parties: one seeks information from the other, that is either motivated, or compelled, to share only the requested information. We define this problem as privacy-preserving sharing of sensitive information and are confronted with two main technical challenges: (1) how to enable this type of sharing such that parties learn no information beyond what they are entitled to, and (2) how to do so efficiently, in real-world practical terms. 
This dissertation presents a set of efficient and provably secure cryptographic protocols for privacy-preserving sharing of sensitive information. In particular, Private Set Intersection (PSI) techniques are appealing whenever two parties wish to compute the intersection of their respective sets of items without revealing to each other any other information (beyond set sizes). We motivate the need for PSI techniques with various features and illustrate several concrete variants that offer significantly higher efficiency than prior work. Then, we introduce the concepts of Authorized Private Set Intersection (APSI) and Size-Hiding Private Set Intersection (SHI-PSI). The former ensures that each set element is authorized (signed) by some mutually trusted authority and prevents arbitrary input manipulation. The latter hides the size of the set held by one of the two entities, thus, applying to scenarios where both set contents and set size represent sensitive information. 
Finally, we investigate the usage of proposed protocols in the context of a few practical applications. We build a toolkit for sharing of sensitive information, that enables (practical) privacy-preserving database querying. Furthermore, motivated by the fast-growing proliferation of personal wireless computing devices and associated privacy issues, we design a set of collaborative applications involving several participants willing to share information in order to cooperatively perform operations without endangering their privacy.
A Theory of Historical Change (2015)

Abstract This chapter presents the theory of historical change that guides the present analysis of the patterns of the Chinese past. The theory can be summarized in one sentence—the dialectic of competition and institutionalization is the major engine of historical change. This theory is based on two premises: first, humans are strongly inclined to compete for domination, individually and collectively; second, the means of humans competition may be ideological, political, economic, or military, or a fusion of several or all of these.
Ternary Neural Networks with Fine-Grained Quantization (2017)

We propose a novel fine-grained quantization (FGQ) method to ternarize pre-trained full precision models, while also constraining activations to 8 and 4-bits. Using this method, we demonstrate a minimal loss in classification accuracy on state-of-the-art topologies without additional training. We provide an improved theoretical formulation that forms the basis for a higher quality solution using FGQ. Our method involves ternarizing the original weight tensor in groups of $N$ weights. Using $N=4$, we achieve Top-1 accuracy within $3.7\%$ and $4.2\%$ of the baseline full precision result for Resnet-101 and Resnet-50 respectively, while eliminating $75\%$ of all multiplications. These results enable a full 8/4-bit inference pipeline, with best-reported accuracy using ternary weights on ImageNet dataset, with a potential of $9\times$ improvement in performance. Also, for smaller networks like AlexNet, FGQ achieves state-of-the-art results. We further study the impact of group size on both performance and accuracy. With a group size of $N=64$, we eliminate $\approx99\%$ of the multiplications; however, this introduces a noticeable drop in accuracy, which necessitates fine tuning the parameters at lower precision. We address this by fine-tuning Resnet-50 with 8-bit activations and ternary weights at $N=64$, improving the Top-1 accuracy to within $4\%$ of the full precision result with $<30\%$ additional training overhead. Our final quantized model can run on a full 8-bit compute pipeline using 2-bit weights and has the potential of up to $15\times$ improvement in performance compared to baseline full-precision models.
Aspect mining in the presence of the C preprocessor (2008)

In systems software, the C preprocessor is heavily used to manage variability and improve efficiency. It is the primary tool to model crosscutting concerns in a very fine-grained way, but leads to extremely tangled and scattered preprocessor code. In this paper, we explore the process of aspect mining and extraction in the context of preprocessor-driven systems. Our aim is to identify both opportunities (extracting conditional compilation into advice) and pitfalls (mining on unpreprocessed code) in migrating preprocessor code to aspects. We distill five trade-offs which give a first impression about the usefulness of replacing the preprocessor by aspects. Preprocessor-driven systems prove to be a real challenge for aspect mining, but they could become on the other hand one of the most promising applications of AOP.
Considerations in the development of nonhuman primate models of combination antiretroviral therapy for studies of aids virus suppression, residual virus, and curative strategies (2013)

Given the vagaries of each specific virus and host species, and cART regimen, each model will require further development and analysis to determine their appropriate application for addressing specific experimental questions.
The grand challenge: building evolutionary technologies (2002)

It is pointed out that many social scientists have repeatedly insisted that group work is not necessarily cooperative and have challenged the assumption that equality among participants is the best and most appropriate approach for group work. The authors accept these observations as a valid starting point and go one step further by describing three key attributes that computed-supported cooperative work (CSCW) technologies must have if they are to achieve wide-scale adoption. They call technologies that have these attributes evolutionary technologies, and the grand challenge is how to build these technologies. These attributes are a comprehensive foundation that supports an unlimited repertoire of human interaction forms, a natural, dynamic change mechanism, and logical starting defaults. To illustrate the concept of an evolutionary technology, the authors discuss several existing CSCW technologies that have some, but not all, of the attributes of an evolutionary technology. They then describe a prototype coordination technology that has all three attributes; it is considered to be an exemplary evolutionary technology.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Efficacy of reverse transcriptase-polymerase chain reaction screening for micrometastic disease in axillary lymph nodes of breast cancer patients. (1998)

Pathologic examination of axillary lymph nodes (ALNs) may miss micrometastases in 30 per cent of breast cancer patients. We have developed a multimarker reverse transcriptase-polymerase chain reaction (RT-PCR)-based screening method that detects histopathologically positive ALNs with a 5 per cent false-negative rate. The purpose of this study was to compare this RT-PCR methodology with histopathology with regard to sensitivity and cost. Pathologically negative ALNs from 35 breast cancer patients were re-evaluated by a single pathologist in a blinded fashion using serial sectioning with immunohistochemical staining. Histopathologic results were then compared with those of RT-PCR. Cost analysis was performed based on standard charges for these methods. RT-PCR identified micrometastases in 14 of 35 pathologically negative nodes. Serial sectioning and immunohistochemical staining identified micrometastases in two cases, with RT-PCR positive for one of these. The charge per specimen for performing routine histopathologic examination was $380, serial sectioning and immunohistochemical staining $787, and RT-PCR $125. RT-PCR appears to be more sensitive at detecting ALN micrometastasis than histopathologic examination even with serial sectioning and immunohistochemical staining. If micrometastatic breast cancer detected by RT-PCR proves to be clinically relevant, it could be a more effective screening methodology with significant cost savings as compared to currently available pathologic examinations.
A Methodology for Automatic Insertion of Selective TMR in Digital Circuits Affected by SEUs (2009)

In this paper, a methodology to perform automatic selective TMR insertion on digital circuits is presented, having as a constraint the required reliability level. Such reliability is guaranteed while reducing the area compared to TMR. In addition, a performance enhancement is proposed in order to guarantee a computation time feasible for this automatic selective TMR insertion methodology. It focuses on the choice of a starting point close enough to an optimal solution. The method consists in the analysis of the topological features of the target circuit which will help the optimization engine to identify those flip-flops more susceptible to be tripled depending on the showed sensitivity to SEUs.
Quantum dots light emitting devices on MEMS: microcontact printing, near-field imaging, and early cancer detection (2011)

Controlled patterning of light emitting devices on semiconductors and micro-electro-mechanical systems (MEMS) enables a vast variety of applications such as structured illumination, large-area flexible displays, integrated optoelectronic systems and micro-total analysis systems for real-time biomedical screening. We have demonstrated a series of techniques of creating quantum dot-based (QD) patterned inorganic light emitting devices at room temperature on silicon (Si) substrate. The innovative technology was translated to create localized QD-based light sources for two applications: (1) Three-dimensional scanning probe tip structures for near field imaging. Combined topographic and optical images were acquired using this new class of "self-illuminating" probe in commercial NSOM. The emission wavelength can be tuned through quantum-size effect of QDs. (2) Multispectral excitation sources integrated with microfluidic channels for tumor cell analyses. We were able to detect the variation of sub-cellular features, such as the nucleus-to-cytoplasm ratio, to quantify the absorption at different wavelength upon the near-field illumination of individual tumor cells towards the determination of cancer developmental stage.
A novel method for preparing vertically grown single-crystalline gold nanowires (2008)

A surfactant-free, template-less and seed-less method, namely the thermal-assisted photoreduction (TAP) process, has been developed to synthesize vertically grown Au nanowires (30–80 nm in diameter and about 2 µm in length) on the surface of thin film titanium dioxide (TiO2), which is locally excited by blackbody radiation. The Au nanowires thus produced are single-crystalline with a preferred growth direction. The electrical behavior investigated using a nanomanipulation device indicates that the Au nanowires possess an excellent electrical resistivity of about 3.49 × 10−8 Ω m.
Induction of MET by Ionizing Radiation and Its Role in Radioresistance and Invasive Growth of Cancer (2011)

IR induces overexpression and activity of the MET oncogene through the ATM-NF-κB signaling pathway; MET, in turn, promotes cell invasion and protects cells from apoptosis, thus supporting radioresistance. Drugs targeting MET increase tumor cell radiosensitivity and prevent radiation-induced invasiveness.
Chondroitin sulphate N-acetylgalactosaminyl-transferase-1 inhibits recovery from neural injury (2013)

Extracellular factors that inhibit axon growth and intrinsic factors that promote it affect neural regeneration. Therapies targeting any single gene have not yet simultaneously optimized both types of factors. Chondroitin sulphate (CS), a glycosaminoglycan, is the most abundant extracellular inhibitor of axon growth. Here we show that mice carrying a gene knockout for CS N-acetylgalactosaminyltransferase-1 (T1), a key enzyme in CS biosynthesis, recover more completely from spinal cord injury than wild-type mice and even chondroitinase ABC-treated mice. Notably, synthesis of heparan sulphate (HS), a glycosaminoglycan promoting axonal growth, is also upregulated in TI knockout mice because HS-synthesis enzymes are induced in the mutant neurons. Moreover, chondroitinase ABC treatment never induces HS upregulation. Taken together, our results indicate that regulation of a single gene, T1, mediates excellent recovery from spinal cord injury by optimizing counteracting effectors of axon regeneration--an extracellular inhibitor of CS and intrinsic promoters, namely, HS-synthesis enzymes.
Electrophoretic deposition of negatively charged tetratitanate nanosheets and transformation into preferentially oriented TiO2(B) film (2002)

A tetrabutylammonium–H2Ti4O9·xH2O intercalation compound was obtained by a guest exchange reaction between tetrabutylammonium hydroxide and an ethylammonium–H2Ti4O9·xH2O intercalation compound, and its dispersion state in aqueous and non-aqueous solutions were studied. Spontaneous exfoliation of H2Ti4O9·xH2O into colloidal nanosheets occurred when the tetrabutylammonium–H2Ti4O9·xH2O intercalation compound was dispersed in water, methyl alcohol, isopropyl alcohol, acetonitrile, N,N-dimethylformamide, dimethyl sulfoxide, and propylene carbonate, while exfoliation did not occur in tetrahydrofuran. A tetrabutylammonium–H2Ti4O9·xH2O film was obtained by a reassembly process by casting the colloidal suspension containing exfoliated nanosheets, while a H2Ti4O9·xH2O film was directly obtained by electrophoretic deposition. Thermal treatment of the electrophoretically deposited film led to an oriented TiO2(B) film with the (0k0) planes lying perpendicular to the substrate.
