Letters or the Autobiography of Writing (1988)

When one writes, it can well get And that is not just the ink, which spreads itself out on the paper, on the white of the paper about which Kafka says that it comes to no end: it burns out one's eyes and that is why one writes. Seldom has there been a love which so plays itself out on paper as Kafka's love toward Milena, or is it not perhaps that there is no love without paper? When someone speaks, it gets light. As it was with the threeyear-old child, whom Freud recollects once having heard speak out of a dark room: Auntie, talk to me; I'm afraid because it's so dark. The objection of the Aunt, How would that help? You can't even see me, is thus dismissed by the child: That doesn't matter; when someone speaks, it becomes light, an answer which leads Freud to assume that the child is not afraid of dark-
Interfaces for coupled liquid‐phase separation/mass spectrometry techniques. An update on recent developments (2002)

An update is presented covering the latest developments in the interfacing of liquid-phase separation systems and mass spectrometers. The interfacing devices presented are those developed for continuous-flow matrix-assisted laser desorption/ionization, micro- and nano-liquid chromatography/masspectrometry (MS), capillary electrophoresis/MS and on-chip separation technologies/MS. From the information that can be found in the most recent literature on the topic, it is evident that the trend towards the miniaturization of separation and interface devices is gaining ground. This can be rationalized by the substantial gains in sensitivity for the detection and study of extremely low levels of analytes and especially of high molecular mass biopolymers.
A multi-module battery system based on MODBUS for a hybrid aircraft (2012)

Embry-Riddle Aeronautical University (ERAU) team built a gas/electric hybrid aircraft, called EcoEagle, to enter the NASA-funded Green Flight Challenge in 2011. The battery system for EcoEagle consists of multiple battery modules in parallel. Each battery module has a fully functional battery management system (BMS), which is connected to a data bus controlled by a master controller. In this paper, we describe some topics of the design and implementation of the battery system. First, we discuss the structure of the battery system and the advantages of using multiple battery modules to build the battery system. Then, we briefly describe the functions of the BMS of each battery module. Finally, we demonstrate how to use simple MODBUS functions to setup the communications between the master controller and the BMSs to implement various functions of the battery system.

A Genetic Algorithm to Minimize the Total Tardiness for M-Machine Permutation Flowshop Problems (2012)

The m-machine, n-job, permutation flowshop problem with the total tardiness objective is a common scheduling problem, known to be NP-hard. Branch and bound, the usual approach to finding an optimal solution, experiences difficulty when n exceeds 20. Here, we develop a genetic algorithm, GA, which can handle problems with larger n. We also undertake a numerical study comparing GA with an optimal branch and bound algorithm, and various heuristic algorithms including the well known NEH algorithm and a local search heuristic LH. Extensive computational experiments indicate that LH is an effective heuristic and GA can produce noticeable improvements over LH.
Long‐term (48 weeks) effectiveness, safety, and tolerability of erenumab in the prevention of high‐frequency episodic and chronic migraine in a real world: Results of the EARLY 2 study (2021)

Long-term (48-week) erenumab treatment provides sustained effectiveness, safety, and tolerability in real-life patients with HFEM or CM with ≥3 prior preventive treatment failures. The dose of 140 mg was required in most patients along the study and should be taken into consideration as the starting dose. Allodynia (in HFEM), male sex, and baseline migraine frequency (in CM) might represent positive responsiveness predictors. Conversely, psychiatric comorbidities and multiple prior preventive treatment failures could be negative predictors in patients with CM.
The role of Trivelpiece–Gould waves in antenna coupling to helicon waves (2000)

It is well known that the simple theory of helicon waves, in which the electron mass me is neglected, is valid only if Ez also vanishes, a condition which is not satisfied in experiment. Exact solutions of cold plasma theory with finite me and Ez predict the existence of additional highly damped Trivelpiece–Gould (TG) modes (H-TG theory), which can greatly modify the nature of helicon discharges. However, most experiments have been explained using only the simple theory for which the helicon waves are undamped. In that case, antenna-plasma-coupling calculations predict infinite resonances. To avoid this problem theorists have set Ez=0 and included finite me effects (the TE-H theory). By comparing the TE-H theory with exact (i.e., closed form) solutions for uniform density, the role of TG modes has been clarified. To do so for nonuniform density, a new algorithm is developed to treat the case of high magnetic fields, when the wave equation becomes singular. The results show that, though the wave patterns are not greatly affected by TG modes except at low magnetic fields or near the radial boundary, the kz spectrum and radial profile of the energy deposition are greatly modified. In particular, the peaks in the TE-H-mode spectrum, which lead to predictions of erroneously high antenna loading, are suppressed and broadened by the TG modes which also produce high edge absorption. Both the TE-H and exact theories give maximum antenna loading for 12me(ω/k)2≈10–100 eV, in contrast to several hundred electron volts predicted by the simple theory.
A Self‐Powered, Sub‐nanosecond‐Response Solution‐Processed Hybrid Perovskite Photodetector for Time‐Resolved Photoluminescence‐Lifetime Detection (2016)

A self-powered,solution-processed perovskite photodetector with sub-nanosecond response time is presented. Eliminating charge trapping and removing the constraints from the resistance-capacitance constant increases the response speed, which enables them to be applied in a homemade, time-resolved photoluminescence system that successfully resolves the decay process of typical fluorescence and phosphorescent materials with a recombination lifetime from several nanoseconds to microseconds.
A truncated protein kinase domain of the large subunit of herpes simplex virus type 2 ribonucleotide reductase (ICP10) expressed in Escherichia coli. (1991)

The amino-terminal domain of the large subunit of herpes simplex virus type 2 ribonucleotide reductase (ICP10) contains a serine/threonine-specific protein kinase that has characteristics of a growth factor receptor (Chung, T. D., Wymer, J. P., Smith, C. C., Kulka, M., and Aurelian, L. (1989) J. Virol. 63, 3389-3398; Chung, T. D., Wymer, J. P., Kulka, M. Smith, C. C., and Aurelian, L. (1990) Virology 179, 168-178). To characterize this protein kinase (PK) domain further we constructed a bacterial expression vector (pJL11) containing DNA sequences encoding ICP10 amino acid residues 1-445. Bacteria containing pJL11 were induced to express a 29-kDa protein (designated pp29la1) that represents a truncated portion of the ICP10-PK domain (includes PK catalytic motifs I-V) as demonstrated by immunoprecipitation with antibodies that recognize different antigenic domains, competition studies with extracts of ICP10-positive eukaryotic cells, and peptide mapping.pp29la1 has autophosphorylating and transphosphorylating activity for calmodulin. The enzyme is activated by Mn2+ but not by Mg2+ ions, and autophosphorylation is inhibited by histone. It differs from the authentic ICP10-PK in that phosphorylation is specific only for threonine.
Microlocal Analysis of the X-Ray Transform with Sources on a Curve (2003)

Load Distribution Algorithm Based on Transcoding Time Estimation for Distributed Transcoding Servers (2010)

As a result of improvements in wireless communication technologies, a multimedia data streaming service can be provided for mobile clients such as PDAs and cellular phones. Because mobile devices have low computing power and work on a low network bandwidth, a transcoding technology is needed to adapt the original streaming media for mobile environments. To provide quality of service, original encoded media are transcoded within limited time and transmitted to clients without ceasing and jittering phenomena. In particular, when large-scale mobile clients demand streaming services, load distribution methods among distributed transcoding servers have a tremendous impact on the total number of quality of service streams. In this paper, a new load distribution method is proposed based on transcoding time estimation with transcoding servers' information, movie information and target transcoding bit-rate. In experiments, the proposed method produces the best performance scalability according to the increase of transcoding servers.
Mobile-Phone Antenna Design (2012)

This paper is a survey of internal antennas in mobile phones from 1997 to 2010. It covers almost 60 GSM and 3G handsets, ranging from the first GSM handset with an internal antenna to the current Nokia, Sony-Ericsson, Motorola, and Apple handsets. The paper discusses different types of mobile-phone antennas, feeding structures, active antennas, isolation, and antenna loading techniques. This paper examines different design techniques for mobile-phone antennas, and the limitations of antenna design due to manufacturing technologies and the effect of handset materials. Antenna performance parameters, including S parameters, radiation efficiency, SAR, and TRP/TIS are reported for the surveyed handsets. The effective antenna volume for every antenna is calculated, in order to determine the average volume/space required for each antenna type and the corresponding performance. Some of the handsets are further simulated using commercial electromagnetic simulators to illustrate the electromagnetic-field distributions. This paper summarizes the antenna design parameters as a function of handset performance, and presents a short summary of design procedure.

Purification and Characterization of Two Isozymes of Chlorophyllase from Mature Leaves of Chenopodium album (1997)

Chlorophyllase (Chlase) was purified from mature leaves of Chenopodium album, and its enzymatic properties were investigated. Chlase was extracted from acetone powder of C. album and purified by the following chroma-tographic procedures: hydrophobic chromatography, Con A Sepharose, Heparin affinity chromatography, Mono Q ion-exchange chromatography, and gel-filtration. Con A Sepharose affinity chromatography and gel-filtration were the most effective steps on the purification. On Mono Q chromatography, the Chlase preparation separated into two major and one minor fractions that exhibited Chlase activity. The two major Chlases were purified to homogeneity. Their molecular masses were estimated as 41.3 kDa and 40.2 kDa by SDS-PAGE. The optimum pH and Km values of these two Chlases were similar. Their N-terminal amino acid sequences were almost identical except for a deletion in the tenth amino acid residue in one of the Chlase; there was no homologous protein detected by database search.

Improving the Performance of Iris Recogniton System Using Eyelids and Eyelashes Detection and Iris Image Enhancement (2006)

Iris recognition gets more and more attention for its high accuracy rate. However, the iris images are often occluded by eyelids and eyelashes partly and if these noises can't be removed the performance of iris recognition system will be degraded badly. On the other hand low contrast and non-uniform brightness will also increase the difficulty of feature extraction and matching. In this paper an efficient method for eyelids and eyelashes detection and iris image enhancement is described which includes two parts mainly. In the first part, eight eyelids/eyelashes models are presented and different model corresponds to different eyelids and eyelashes type. The real eyelids/eyelashes areas can be detected by comparing the variation of every sub-block of each eyelids/eyelashes model. The second part is iris enhancement, in this part the background illumination of the normalized iris image is estimated and subtracted from it. Then histogram equalizing and viener filtering are implemented to enhance the normalized iris image. In order to evaluate the necessity of this method an iris recognition algorithm based on 1D gabor filter is developed and results are encouraging in CASIA 1.0 iris images sets.
Generic Programming for High Performance Numerical Linear Algebra (2004)

We present a generic programming methodology for expressing data structures and algorithms for high-performance numerical linear algebra. As with the Standard Template Library #14#, our approach explicitly separates algorithms from data structures, allowing a single set of numerical routines to operate with a wide variety of matrix types, including sparse, dense, and banded. Through the use of C++ template programming, in conjunction with modern optimizing compilers, this generality does not come at the expense of performance. In fact, writing portable high-performance codes is actually enabled through the use of generic programming because performance critical code sections can be concentrated into a small number of basic kernels. Two libraries based on our approach are described. The Matrix Template Library #MTL# is a high-performance library providing comprehensive linear algebra functionality. The IterativeTemplate Library, based on MTL, extends the generic programming a...

CSEM data uncertainty analysis for 3D inversion (2009)

Inaccurate navigation can be an important source of measurement errors in CSEM data. Improved algorithms for estimating receiver orientation yield values for the uncertainty in the resulting angles. We show how linear error propagation analysis can be used for improved 3D inversion by accounting for such uncertainty in the data weighting scheme.
A tightly coupled finite field arithmetic hardware in an FPGA-based embedded processor core for elliptic curve cryptography (2008)

This work presents the implementation of a tightly-coupled hardware architectural enhancement to the Altera FPGA-based Nios II embedded processor. The goal is to accelerate finite field arithmetic operations in the binary fields of F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">163</sup> and F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">193</sup> , for application in a high-performance embedded system implementing elliptic-curve cryptography (ECC). The concept is to augment the embedded processor with a few custom instructions for fast finite field arithmetic operations. Instead of a co-processor, hardware acceleration of the arithmetic operation is provided by custom logic tightly coupled to the processor core and directly controlled by the instruction stream. This concept, which may be considered as a hardware-software codesign approach, is evaluated by prototyping an elliptic curve cryptosystem (ECC) on an Altera Stratix FPGA development board. Experimental results show that for the point multiplication operation, which is the core operation in an ECC computation, the implementation with custom instructions and tightly-coupled hardware is about 50% faster than the coprocessor based hardware.
Fast LBP Face Detection on Low-Power SIMD Architectures (2014)

This paper presents an embedded implementation of a face detection method based on boosted LBP features for Single Instruction Multiple Data (SIMD) architectures. The implementation exploits parallelism and data reuse in the detection algorithm and is integrated into CogniVue's Gen-1 APEX platform, which uses a SIMD design and is extremely energy efficient. The proposed embedded face detection system runs at 5 VGA frames per second, while providing similar accuracy to the PC version of the LBP face detection algorithm included in the OpenCV library.
Principles of distributed feedback and distributed Bragg-reflector lasers (1974)

Wave propagation in periodic waveguides is analyzed by decomposing the eigen Bloch waves into traveling-wave components. It is shown that the principal components consist of a primary forward wave, a primary backward wave, and their Bragg-scattered secondary waves. One important parameter is the coupling constant <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</tex> due to Bragg scattering, which relates the secondary wave to the respective primary wave. Laser threshold condition is then obtained by applying the continuity of tangential <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</tex> and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">H</tex> at the two boundaries. The results thus obtained are general and applicable to thin-film lasers with various waveguide structures. The laser threshold condition of thin-film Bragg lasers is expressed in terms of two effective reflection coefficients for easy comparison with conventional lasers. For appreciable reflection, a significant change either in the propagation constant or in the coupling constant is required. Two basic types of thin-film Bragg lasers are distributed-feedback (DFB) lasers in which Bragg scattering is confined to the active medium and distributed-Bragg-reflector (DBR) lasers in which Bragg scattering is limited to regions beyond the active medium. The threshold gain, frequency control, and mode selectivity for both types are analyzed and the analyses are applied to GaAs and Nd lasers. It is shown that DBR lasers should have a lower threshold gain and a better mode selectivity than DFB lasers. For distributed-feedback effect to play a significant role in thin-film Bragg lasers, the product kL <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">int</inf> must be greater than unity where <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">K</tex> is the distributed-feedback coefficient and L <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">int</inf> is the interaction length. Advantages for having periodic structures outside the active medium so as to relax constraints on <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</tex> and L <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">int</inf> are also discussed.
