A 1.83 $\mu$J/Classification, 8-Channel, Patient-Specific Epileptic Seizure Classification SoC Using a Non-Linear Support Vector Machine (2015)

A non-linear support vector machine (NLSVM) seizure classification SoC with 8-channel EEG data acquisition and storage for epileptic patients is presented. The proposed SoC is the first work in literature that integrates a feature extraction (FE) engine, patient specific hardware-efficient NLSVM classification engine, 96 KB SRAM for EEG data storage and low-noise, high dynamic range readout circuits. To achieve on-chip integration of the NLSVM classification engine with minimum area and energy consumption, the FE engine utilizes time division multiplexing (TDM)-BPF architecture. The implemented log-linear Gaussian basis function (LL-GBF) NLSVM classifier exploits the linearization to achieve energy consumption of 0.39 μ J/operation and reduces the area by 28.2% compared to conventional GBF implementation. The readout circuits incorporate a chopper-stabilized DC servo loop to minimize the noise level elevation and achieve noise RTI of 0.81 μ Vrms for 0.5-100 Hz bandwidth with an NEF of 4.0. The 5 × 5 mm (2) SoC is implemented in a 0.18 μm 1P6M CMOS process consuming 1.83 μ J/classification for 8-channel operation. SoC verification has been done with the Children's Hospital Boston-MIT EEG database, as well as with a specific rapid eye-blink pattern detection test, which results in an average detection rate, average false alarm rate and latency of 95.1%, 0.94% (0.27 false alarms/hour) and 2 s, respectively.
Semiconductor Mode-Locked Laser for High-Speed OTDM Transmission (2006)

Das Ziel dieser Arbeit ist die Untersuchung von modengekoppelten Halbleiterlasern für die Anwendung als Sender Pulsquelle in einem optischen Zeitmultiplex (OTDM) System mit Datenraten von bis zu 640 Gbit/s mit Amplitudenmodulation (OOK) oder differentieller Phasenmodulation (DPSK). Bis zu dieser Arbeit wurden Halbleiterlaser nicht für Datenraten über 160 Gbit/s und in Transmissionsexperimenten mit dem DPSK Modulationsformat eingesetzt. Mit den Halbleiterlasern wurden Pulsfolgen mit einer Wiederholrate von 10 GHz oder 40 GHz mit geringem Phasen- und Amplitudenrauschen erzeugt. Dabei wurden Halbleiterlaser in externer Kavität und in monolithischer Kavität betrachtet. Verbesserte Rauscheigenschaften der erzeugten Pulsfolgen wurden auf Kosten der Pulsbreite der generierten Pulsfolge erreicht. Ein modulares Konzept bestehend aus den unabhängigen Einheiten Pulserzeugung, Pulsverkürzung und Pulsformung wurde aufgebaut, um eine Pulsquelle zur Erzeugung von Pulsen im Subpikosekundenbereich mit geringerem Phasenrauschen zu erhalten. Die von dem modularen Pulsgenerator erzeugte Pulsfolge bestand aus Pulsen mit einer Pulsbreite von 0.4 ps und einen Signal-zu-Rausch-Kontrast von mehr als 40 dB. Das Phasenrauschen σ(rms) konnte in Einseitenbandmessungen [Frequenzbereich 100 Hz, 10 MHz] auf unter 100 fs verringert werden. Die erzeugte 10 bzw. 40 GHz Pulsfolge wurde zu einer Datenrate von 640 Gbit/s in einer Polarisationsebene und auf einer Wellenlänge gemultiplexed. Eine Verwendbarkeit der generierten Pulsfolge für eine Übertragung auf einer Faserstrecke von 160 km Länge wurde bestätigt. Die Untereinheiten des modular aufgebauten Pulsgenerators können unabhängig voneinander eingesetzt werden, die Pulsquelle zur Erzeugung von Pulsfolgen mit einer Wiederholrate von 10 bzw. 40 GHz, die Pulskompression zur Verkürzung der Pulsbreite von mehr als 3 ps auf unter 0.5 ps und der Pulsformer zum Entfernen von Pulssockeln bzw. zur Erhöhung des Signal-zu-Rausch-Kontrasts auf über 40 dB. Die Phasenstabilität der erzeugten rauscharmen Pulsfolgen blieb bei der Pulskompression und der Erhöhung des Signal-zu-Rausch-Kontrasts durch nichtlineare Fasereffekte erhalten. Die Verwendbarkeit der modularen Pulserzeugung für einen DPSK Transmitter wurde in einer back-to-back Messung eines 320 Gbit/s DPSK Datensignal nachgewiesen. Die erreichten Fehlerraten in der back-to-back Konfiguration erlauben auch eine Erhöhung der Datenrate auf 640 Gbit/s, sofern Verfahren zur "forward error correction" verwendet werden.

Resource-Activity Critical-Path Method for Construction Planning (2003)

In this paper, a practical method is developed in an attempt to address the fundamental matters and limitations of existing methods for critical-path method (CPM) based resource scheduling, which are identified by reviewing the prior research in resource-constrained CPM scheduling and repetitive scheduling. The proposed method is called the resource-activity critical-path method (RACPM), in which (1) the dimension of resource in addition to activity and time is highlighted in project scheduling to seamlessly synchronize activity planning and resource planning; (2) the start/finish times and the floats are defined as resource-activity attributes based on the resource-technology combined precedence relationships; and (3) the “resource critical” issue that has long baffled the construction industry is clarified. The RACPM is applied to an example problem taken from the literature for illustrating the algorithm and comparing it with the existing method. A sample application of the proposed RACPM for planning a footbridge construction project is also given to demonstrate that practitioners can readily interpret and utilize a RACPM schedule by relating the RACPM to the classic CPM. The RACPM provides schedulers with a convenient vehicle for seamlessly integrating the technology/process perspective with the resource use perspective in construction planning. The effect on the project duration and activity floats of varied resource availability can be studied through running RACPM on different scenarios of resources. This potentially leads to an integrated scheduling and cost estimating process that will produce realistic schedules, estimates, and control budgets for construction.

Using historical data from source code revision histories to detect source code properties (2006)

In this dissertation, we describe several techniques for using historical data mined from the source code revision histories of software projects to determine important properties of the source code. These properties are then used to improve the results of various bug-finding techniques as well as to provide documentation to the developer. We describe a method to mine source code revision histories, in this case CVS repositories, to extract relevant information to be fed into a static source code bug finder for use in improving the results generated by the bug finding tool. We apply this technique to the CVS repositories of two widely used open source software projects, Apache httpd and Wine. We show how source code revision history can be used to reduce false positives from a static source code checker that identifies the misuse of values returned from a function call. A method of mining source code revision histories for the purpose of learning about project specific idioms is then discussed. Specifically, we show how source code revision history can be used to identify patterns of calling sequences that describe how functions in the software should be used in relation to each other. With this data, we are able to find bugs in the source code, document API usage and identify refactoring events. In short, this dissertation shows that it is possible to automatically determine meaningful properties of the source code from studying source code changes cataloged in the software revision history.
Polymerase Chain Reaction Examination of Urine for Rapid Detection of Mycobacterium Tuberculosis in the Genitourinary Tract (2001)

OBJECTIVE: For rapid detection of Mycobacterium tuberculosis existence in the genitourinary tract a polymerase chain reaction was established to examine urine bacteria. MATERIALS AND METHODS: By using 3 DNA primers (MPB, INS, and Pt)and the PCR method, totally 50 specimens of urine(12 cases of definitive TB, 19 cases of suspicious TB, and 19 cases of ordinary UTI), 2 specimens of local discharge, and 3 specimens of resected tissues were analyzed. RESULTS: The positive detection rates of the 3 DNA primers, MPB, INS, and Pt, in definitive TB patients(true-positive rate)were 88.3%, 75.0%, and 41.7%; in suspicious TB patients(diagnostic rate)were 31.6%, 42.1%, and 26.3%; and in UTI patients(false-positive rate)were 15.8%, 36.8%, and 10.5%. MBP-nested PCR had the highest diagnostic power for TB infection in urine with an acceptable false-positive rate. The INS probe is not suitable for detection because both its high true-and false-positive rate were high, while the Pt probe had the lowest false-positive rate but also a low true- positive rate. Only l out of 17 cases (11.8%) showed a positive smear examination and TB culture, respectively. Interestingly, 4 patients after anti-TB triple therapy still had a positive PCR reaction in their urine. CONCLUSIONS: These results provide us with an early diagnosis of M. tuberculosis infection in the genitourinary tract which can improve the treatment outcome of patients by using MPB-nested PCR. However, more-sensitive primers should be developed in the future for increasing the diagnostic rate.
Operative risks in patients with colorectal cancer. (1985)

This study emphasizes the risks in the operative treatment of patients with colorectal cancer. In dissecting our overall operative mortality of 7.4 per cent in consecutive patients over a 5-year period, three factors influencing the outcome were identified. These were the age of the patient, the stage of the disease, and the availability of preoperative bowel preparation by mechanical cleansing and antibiotic suppression of the colonic bacterial flora. Earlier diagnosis and elective resection of prepared bowel offers marked improvement in the operative risk for patients with colorectal cancer.

DATE OF CONFINEMENT PREDICTION FROM SERUM DIAMINE OXIDASE DETERMINATION IN EARLY PREGNANCY (1976)

A reliable assessment of the date of confinement is often important in early pregnancy. In many pregnancies the menstrual history is in doubt or the size of the uterus does not correspond to the last menstrual period. During early pregnancy the rise of serum diamine oxidase (DAO) is confined within narrow limits to certain weeks of gestation. In a series of 189 patients from the 6th to 16th week of pregnancy, the date of confinement was estimated by enzyme determination, and was also calculated by Naegel's formula. Dating by serum DAO was found to be more accurate than the menstrual history, and this technique is recommended for use in routine clinical practice.
A Rubber-Like Protein in Insect Cuticle (1960)

ABSTRACT The cuticle of arthropods is complex and varies enormously in structure, properties and composition even within the same species (cf. Richards, 1951). However, the mechanical behaviour is dominated by materials in the solid state of matter so that the mature cuticles hitherto described in the literature may be classed as solid cuticle. It was therefore surprising to find that certain patches of the exoskeleton in many insects exhibit long-range reversible elasticity of the rubber-like type. This paper describes three examples of rubber-like cuticle from locusts (Orthoptera) and dragonflies (Odonata). Similar structures have been found in all winged insects hitherto examined (Weis-Fogh, unpublished). Essentially the present survey is a qualitative analysis of the material basis for the rubber-like properties of three selected samples, based upon simple tests and techniques. The main conclusion is that the characteristic elasticity is caused by a peculiar protein, called resilin, which differs from other structural proteins also in respect of amino-acid composition (Bailey & Weis-Fogh, 1961). Resilin is insoluble in all solvents which do not break peptide bonds and since it is located as an integral part of the highly organized cuticle it is necessary to analyse the three samples in detail as to structure and many other properties. Only in this way is it permissible to conclude that the elasticity depends on only one type of substance and to characterize it in general terms.
Thiophene/Phenylene/Thiophene-Based Low-Bandgap Conjugated Polymers for Efficient Near-Infrared Photovoltaic Applications (2009)

We have prepared thiophene/phenylene/thiophene (TPT)-based low bandgap conjugated polymers exhibiting tunable energy levels and investigated their application in solar cells. By incorporating various electron-withdrawing comonomers through Stille coupling reactions, we obtained TPT-based donor/acceptor copolymers having bandgaps ranging from 1.0 to 1.8 eV. We compared the absorption spectra, electrochemistry, field effect hole mobility, and photovoltaic properties of these low bandgap TPT derivatives with those of poly(3-hexylthiophene) (P3HT). The absorption coefficients of the thin films fell in the range from 0.77 × 105 to 1.4 × 105 cm−1. These materials displayed sufficiently high hole mobilities (>10−3 cm2 V−1 s−1) for efficient charge extraction and good fill-factors for organic photovoltaic applications. Electrochemical studies indicated desirable HOMO/LUMO levels, with a good correlation between the HOMO energy levels and the open circuit voltage (Voc) when the polymers were blended with fullerene derivative as an electron acceptor. Power conversion efficiencies of up to 4.3% were achieved under AM 1.5G simulated solar light (100 mW cm−2). Our findings suggest that TPT derivatives presenting suitable electron-withdrawing groups are promising photovoltaic materials.

Introduction to the quagga routing suite (2014)

Off-the-shelf routing products are often constrained by being designed to meet specific needs, in terms of both software and hardware. Networking professionals may face problems that require customization of software, or additional processing facilities or data storage, which are not provided for by those products. The Quagga Routing Suite provides implementations of several common routing protocols, distributed over multiple processes communicating via IPC, and support for their development, with source code provided under a modification-friendly license. Quagga can help networking professionals build such custom solutions, in combination with other open source software packages. Quagga also provides a path for network researchers to increase the visibility of their work, making it available to a wider community for potential testing and use, increasing the impact of that research.

Cerebrospinal fluid Aβ<sub>42</sub> levels and <i>APP</i> processing pathway genes in Parkinson's disease (2015)

In addition, results of this exploratory investigation suggest that an APP SNP and an APH1B SNP are marginally associated with PD CSF Aβ42 levels in APOE ɛ4 noncarriers. Further hypotheses generated include that decreased CSF Aβ42 levels are in part driven by genetic variation in APP processing genes. Additional investigation into the relationship between these findings and clinical characteristics of PD, including cognitive impairment, compared with other neurodegenerative diseases, such as AD, are warranted. © 2015 International Parkinson and Movement Disorder Society.

Regulated expression of chimaeric genes containing the 5′-flanking regions of human growth hormone-related genes in transiently transfected rat anterior pituitary tumor cells (1987)

The expression and hormonal regulation of chimaeric genes containing the 5'-flanking regions of the normal human growth hormone (hGH-1), the variant hGH (hGH-2) and chorionic somatomammotropin (hCS-1) genes fused to the chloramphenicol acetyl transferase (CAT) gene has been examined after transient transfection into cultured rat pituitary (GC), and non-pituitary (HeLa and Rat 2) tumor cells. As assessed by levels of CAT activity, the hGH-1 and hCS-1 gene hybrids were expressed at 5- to 25-fold higher levels in GC cells than in HeLa or Rat 2 cells. The hGH-2 gene hybrid was expressed at very low levels in all 3 cell types. Triiodothyronine treatment of transiently transfected GC cells had little effect on CAT activity from the hGH-1 gene hybrid but increased CAT activity from the hCS-1 gene hybrid. A slight but significant increase in CAT expression was detected with both genes after dexamethasone treatment. The data indicate that elements present on the hGH-1 and hCS-1 genes' 5'-flanking DNA are required for the efficient expression of these genes in GC cells.
Analyzing source code identifiers for code reuse using NLP techniques and WordNet (2017)

Massive amount of source codes are available free and open. Reusing those open source codes in projects can reduce the project duration and cost. Even though several Code Search Engines (CSE) are available, finding the most relevant code can be challenging. In this paper we propose a framework that can be used to overcome the above said challenge. The proposed solution starts with a Software Architecture (Class Diagram) in XML format and extracts information from the XML file, and then, it fetches relevant projects using three types of crawlers from GitHub, SourceForge, and GoogleCode. Then it finds the most relevant projects among the vast amount of downloaded projects. This research considers only Java projects. All java files in every project will be represented in Abstract Syntax Tree (AST) to extract identifiers (class names, method names, and attributes name) and comments. Action words (verbs) are extracted from comments using Part of Speech technique (POS). Those identifiers and XML file information need to be analyzed for matching. If identifiers are matched, marks will be given to those identifiers, likewise marks will be added together and then if the total mark is greater than 50%, the .java file will be considered as a relevant code. Otherwise, WordNet will be used to get synonym of those identifiers and repeat the matching process using those synonyms. For connected word identifiers, camel case splitter and N-gram technique are used to separate those words. The Stanford Spellchecker is used to identify abbreviated words. The results indicate successful identification of relevant source codes.
