Wavelength exchange in a highly nonlinear dispersion-shifted fiber: theory and experiments (2002)

With a suitable arrangement of two pumps and two signals with respect to the zero-dispersion wavelength of a fiber, simultaneous wavelength exchange between two signals can be realized by four-wave mixing in the fiber. We have demonstrated near-complete wavelength exchange between two signals at 1573.4 and 1579.9 nm with two 0.25-W pumps in a 1-km-long highly nonlinear dispersion-shifted fiber. We also have evaluated the bit-error-rate performance of wavelength exchange with a 10-Gb/s signal, and obtained a power penalty of less than 1 dB for the exchanged signal.
Deficient repair of O6-methylguanine in lymphocytes from rheumatoid arthritis families may be an acquired defect. (1988)

Deficient repair of the premutagenic DNA lesion O6-methylguanine (O6-MeGua) has been reported in lymphocytes from patients with autoimmune diseases. This was confirmed in the present study of probands with rheumatoid arthritis (RA) and their families. We also noted a significant deficiency in 9/19 spouses (P less than 0.05) and a statistically non-significant deficiency of repair of O6-MeGua in 14/42 first and second degree relatives in comparison with healthy and non-autoimmune disease controls, respectively. A significant correlation of the repair status of O6-MeGua in DNA between individual probands with RA and respective spouses (P less than 0.01) and probands and respective family members (P less than 0.001) supported the idea that an environmental, transmissible agent could influence the expression of the protein, O6-methylguanine-DNA-transferase (O6-MT), involved in the repair of O6-MeGua. The present results, however, cannot entirely exclude an additional hereditary influence.
Principle of a Submerged Freeze Gripper for Microassembly (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> The development of reliable and repeatable strategies to manipulate and assemble microobjects lies in the efficiency, reliability, and precision of the handling processes. In this paper, we propose a thermal-based microgripper working in an aqueous medium. Manipulating and assembling in liquid surroundings can indeed be more efficient than in dry conditions. A comparative analysis of the impact of dry and liquid media on surface forces, contact forces, and hydrodynamic forces is shown. In addition, ice grippers represent flexible manipulation solutions. Nevertheless, when micromanipulation tasks are performed in air, capillary forces can drastically perturb the release. Our submerged freeze microgripper exploits the liquid surroundings to generate an ice droplet to catch microobjects, and to avoid capillary forces during the release. The thermal principle, the first microgripper prototype, an ice generation simulation, and the first tests are presented. The main objective is to validate the manipulation principle. Further research will be focused on control and optimization of the ice generation and the miniaturization of the system. </para>

A Phase II Immunochemotherapy Study with Alemtuzumab, Fludarabine, Cyclophosphamide, and Doxorubicin (Campath-FCD) in Peripheral T-Cell Lymphomas. (2006)

Abstract The majority of entities of peripheral (mature) T-cell lymphomas (PTCL) have an unfavourable prognosis as compared to aggressive B-cell lymphomas. This difference has become even more pronounced since the introduction of CD20 antibodies in B-cell lymphoma therapy. The purpose of the present study was to investigate the feasibility and efficacy of the combination of the monoclonal antibody alemtuzumab with chemotherapy consisting of fludarabine, cyclophosphamide and doxorubicin in PTCL. Patients were treated with alemtuzumab 3, 10, 30, 30 mg, days 1–4, fludarabine 25 mg/m2 days 2–4, cyclophosphamide 600 mg/m2 day 3, and doxorubicin 50 mg/m2 day 4. Initially, patients with primary diagnosis, with first relapse, or with primary refractory disease were included. Excluded were patients with primary cutaneous T-cell lymphomas and ALK-positive large cell anaplastic T-cell lymphomas. So far, 37 patients have been included and 30 are evaluable for response and toxicity: 13 patients with PTCL-unspecified, 9 with angioimmunoblastic lymphoma, two with ALK negative anaplastic large cell lymphoma, two with enteropathy-associated T-cell lymphoma, two with nasal-type NK-/T-cell lymphoma, one with an NK-cell lymphoma, and one with a T-PLL. 19/30 patients were enrolled with primary diagnosis of PTCL and 11/30 patients with relapse or refractory disease. The median age was 56 years (range 21–77); 69% of the patients had an intermediate high or high prognostic score according to the international prognostic index. In patients with primary diagnosis the remission rate was 63% (12/19; CR 58%, PR 5%), four patients were primary progressive, and three patients dropped out because of treatment associated complications. Of the 12 responding patients 10 are in ongoing remission at 2+, 2+, 3+, 6+, 12+, 14+, 26+, 27+, 38+, and 39+ months, respectively. Two patients relapsed after being in CR for 23 and 34 months, respectively. In the group of relapsed or refractory patients three CR and two PR (45% overall response) were observed. The main toxicity was leukocytopenia (65% grade III and IV of all evaluable treatment cycles), other grade III and IV toxicities included anemia (17%), thrombocytopenia (35%), infections (16%), pruritus/skin reactions (11%), nausea/emesis (6%), mucositis (4%), and cardiac toxicity (4%, two patients with relapsed disease after pre-treatment with CHOP-like regimens developed severe heart failure and died). 12 (40%) patients reactivated CMV, however, 10 without developing CMV-related disease. In conclusion, the combination is an effective first-line regimen for peripheral T-cell lymphoma, however, regarding the general outcome a longer follow-up period of a larger patient population is required. Because the results were not convincing in relapsed and refractory disease and because of two heart failures in this group, the study was closed for relapsed and refractory patients, but is ongoing for first-line treatment of peripheral T-cell lymphomas.
RETRACTED: Using Data Mining Methods for Predicting Sequential Maintenance Activities (2018)

A data mining approach is integrated in this work for predictive sequential maintenance along with information on spare parts based on the history of the maintenance data. For most practical problems, the simple failure of one part of a given piece of equipment induces the subsequent failure of the other parts of said equipment. For example, it is frequently observed in mining industries that, like many other industries, the maintenance of conventional equipment is carried out in sequence. Besides, depending on the state of parts of the equipment, many parts can be consumed and replaced. Consequently, with a group of spare parts consumed sequentially in various maintenance activities, it is possible to discover sequential maintenance activities. From maintenance data with predefined support or threshold values and spare parts information, this work determines the sequential patterns of maintenance activities. The proposed method predicts the occurrence of the next maintenance activity with information on the consumed spare parts. An industrial real case study is presented in this paper and it is well-noticed that our experimental results shed new light on the maintenance prediction using data mining.

Digging for data structures (2008)

Because writing computer programs is hard, computer programmers are taught to use encapsulation and modularity to hide complexity and reduce the potential for errors. Their programs will have a high-level, hierarchical structure that reflects their choice of internal abstractions. We designed and forged a system, Laika, that detects this structure in memory using Bayesian unsupervised learning. Because almost all programs use data structures, their memory images consist of many copies of a relatively small number of templates. Given a memory image, Laika can find both the data structures and their instantiations.We then used Laika to detect three common polymorphic botnets by comparing their data structures. Because it avoids their code polymorphism entirely, Laika is extremely accurate. Finally, we argue that writing a data structure polymorphic virus is likely to be considerably harder than writing a code polymorphic virus.

Potential column chromatography for ionic Ga-68. II: Organic ion exchangers as chromatographic supports. (1980)

A potential Ge-68 leads to Ga-68 generator system, based on the adsorption of Ge-68 from a dilute hydrofluoric acid eluent onto a commercially available organic anionexchange resin, is described. The distribution coefficients between the resin and dilute hydrofluoric acid were measured for germanium and gallium, and the breakthrough of germanium from a generator column determined. Using 0.01 N HF, the Kd values are 27 and greater than 4,000 for gallium and germanium, respectively. Gallium-68 can be quantitatively collected with 4 ml of 0.01 N HF. After neutralization, this provides a biologically safe concentration of NaF for injection. The breakthrough levels of germanium-68 remain lower than 10(-4) for up to 600 collections.
Gas Flow Sensing with a Piezoresistive Micro-Cantilever (2006)

This study exploits a bending-up cantilever caused by residual stress to manufacture a micro gas flow sensor. MEMS techniques are used to deposit a silicon nitride layer on a silicon wafer to create a piezoresistive structure. A platinum layer is deposited on the silicon nitride layer to form a resistor and the structure is then etched to form a freestanding micro-cantilever. When an airflow passes over the cantilever beam, a deformation of the resistor occurs. Variations in the airflow velocity are then determined by measuring the corresponding change in the resistance using an LCR meter. The experimental data indicate that the proposed gas flow sensor has a high sensitivity (0.0533 Omega/ms <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> ) and a high measurement limit (45 ms <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> ).
Polarization division multiple access with polarization modulation for LOS wireless communications (2011)

Abstract In this paper, we discuss a potential multiple access and modulation scheme based on polarized states (PS) of electromagnetic (EM) waves for line-of-sight (LOS) communications. The proposed scheme is theoretic different from the existing polar modulation for EDGE and WCDMA systems. We propose the detailed bit representation (modulation) and multiple access scheme using PS. Because of the inflexibility of polarization information in the time and frequency domains, as well as independence of frequency and space, the polarization information can be used independently for wireless communications, i.e., another independent resource domain that can be utilized. Due to the independence between the PS and the specific features of signals (such as waveform, bandwidth and data rate), the discussed polarization division multiple access (PDMA) and polarization modulation (PM) are expected to improve the spectrum utilization effectively. It is proved that the polarization filtering technique can be adopted in the PDMA-PM wireless communications to separate the multiuser signals and demodulate the bit information representing by PS for desired user. Some theoretical analysis is done to demonstrate the feasibility of the proposed scheme, and the simulation results are made to evaluate the performance of the suggested system.
Physicochemical Characterization of Hemicelluloses from Steamed Aspen and Birchwood (1999)

Abstract The three hemicellulosic preparations, isolated from aspen by steam treatment (without explosion) at 180°C, 190°C, and 200°C for lOmin. and two hemicellulosic fractions, extracted from birchwood by steam-explosion treatment at 190°C and 210°C for lOmin, were comprised mainly of acetyl- and 4-O-methylglucuronosyl substituted xylans. When aspen was steam-treated without explosion, the hemicelluloses, extracted by water, contained relatively higher amounts of associated lignin (14.6–26.6%). Treatment of birchwood by steam-explosion yielded hemicelluloses which contained relatively lower amounts of associated lignin (6.2–9.5%). All five hemicellulosic fractions had a lower degree of polymerization (DP, 44-63), with molecular-average weights ranging between 6610 and 9390.
Human Taste and Umami Receptor Responses to Chemosensorica Generated by Maillard-type <i>N</i><sup>2</sup>-Alkyl- and <i>N</i><sup>2</sup>-Arylthiomethylation of Guanosine 5′-Monophosphates (2014)

Structural modification of the exocyclic amino function of guanosine 5'-monophosphate (5'-GMP) by Maillard-type reactions with reducing carbohydrates was recently found to increase the umami-enhancing activity of the nucleotide upon S-N(2)-1-carboxyalkylation and S-N(2)-(1-alkylamino)carbonylalkylation, respectively. Since the presence of sulfur atoms in synthetic N(2)-alkylated nucleotides was reported to be beneficial for sensory activity, a versatile Maillard-type modification of 5'-GMP upon reaction with glycine's Strecker aldehyde formaldehyde and organic thiols was performed in the present study. A series of N(2)-(alkylthiomethyl)guanosine and N(2)-(arylthiomethyl)guanosine 5'-monophosphates was generated and the compounds were evaluated to what extent they enhance the umami response to monosodium L-glutamate in vivo by a paired-choice comparison test using trained human volunteers and in vitro by means of cell-based umami taste receptor assay. Associated with a high umami-enhancing activity (β-value 5.1), N(2)-(propylthiomethyl)guanosine 5'-monophosphate could be generated when 5'-GMP reacted with glucose, glycine, and the onion-derived odorant 1-propanethiol, thus opening a valuable avenue to produce high-potency umami-enhancing chemosensorica from food-derived natural products by kitchen-type chemistry.
An experimental system for processing movement information of vehicle (1978)

This paper presents a proposed experimental system for processing movement information of vehicle. Using self-contained on-line computing processor which computes position and heading angle (azimuth), trajectory of location of vehicle has been successfully displayed by an experimental system implemented. Principles of self-contained computing system are as follows: accurate digital moving pick-ups are set on both sides of vehicle wheels, accumulation of both sides data which are picked periodically is for distance measuring and subtraction of both sides data is for heading computation, self-contained processor computes the location and heading angle, and also presents location data on X-Y recorder and digital displays. Coordinate location and heading computations are performed by electronic hard-ware mechanization. Methods for reduction of induced errors are discussed and experimentally demonstrated.

Absorbance Linearity and Repeatability in Cylindrical Internal Reflectance FT-IR Spectroscopy of Liquids (1990)

This paper reports the results of a program aimed at eliminating the sources of performance variability and excessive nonlinearity that have limited the effectiveness of the cylindrical internal reflectance technique for use in quantitative FT-IR analysis. After discussing the various optical factors that can affect performance, it describes a new adjustment-free optical design which promises to eliminate those factors which lead to data unpredictability. Finally, it summarizes the results of a series of experiments carried out to test the effectiveness of the new design. These confirm the achievement of three significant improvements: an enhancement of band strengths by factors of typically 2.5 to 3, significantly improved absorbance linearity, and a high degree of data repeatability under varied experimental conditions.
The Comparative Study of Communist States (1982)

Communist states are a relatively recent phenomenon. Seventy years ago there were none at all; forty years ago there were only three, the USSR and two Asian outposts, Mongolia and Tuva; and as late as 1945 there were only five such states, located for the most part in Eastern Europe (Albania and Yugoslavia as well as the USSR) and also in Asia (North Vietnam and Mongolia, Tuva having in the meantime been absorbed by the USSR). Since then communist regimes have come into existence elsewhere in Eastern Europe (Bulgaria, Romania, Poland, Czechoslovakia, Hungary and the German Democratic Republic), in Latin America (Cuba), and also in Asia (China, North Korea, and most recently Laos and Kampuchea). As a result of these changes there were sixteen states which, at the beginning of the 1980s, could reasonably be classified as communist (Table 1.1). In addition a number of other states, particularly in the developing countries, have adopted some of the institutional features of the communist states such as a single ruling party or a centrally planned economy, and communist or workers' parties have come into existence in virtually every country of the world, some of them claiming independence of any of the existing ruling parties but all of them accepting the authority of Marxism—Leninism.
Correction of high‐order eddy current induced geometric distortion in diffusion‐weighted echo‐planar images (2004)

Diffusion-weighted images acquired with the echo-planar imaging technique are highly sensitive to eddy current induced geometric distortions that vary with the magnitude and direction of the diffusion sensitizing gradients. Such distortions cause misalignment of images acquired with different diffusion strengths and orientations. This in turn can result in errors when calculating maps of the apparent diffusion coefficient and diffusion tensor. Previous correction methods either require separate calibration data or only deal with low-order errors. In this study, we demonstrate a method that can correct for higher-order errors. The method relies on collecting pairs of images with diffusion sensitizing gradients reversed. This paired data are first corrected for shifts and linear distortion and then combined to cancel higher-order errors. All acquired data contribute to the final results. The method has been tested by simulation, on phantoms, on adult volunteers, and on neonatal brain examinations.
Histamine Release from Rat Peritoneal Mast Cells and Cat Paws Induced by Some Neuromuscular Blocking Agents (1971)

Abstract The capacity of some neuromuscular blocking agents to release histamine from rat peritoneal mast cells and cat paws has been investigated. Only nondepolarizing agents were effective in the concentration ranges used. The order of potency was tubocurarine, dimethyltubocurarine, toxiferine‐C, alcuronium, in contrast to published data on their corresponding order of neuromuscular blocking activity. In addition to histamine release, tubocurarine and dimethyltubocurarine induced the efflux of slow reacting substance (SRS) from perfused cat paws. The release evoked by tubocurarine or dimethyltubocurarine was reduced by potassium cyanide and lack of Ca ++ . It is concluded that the interonium distance in neuromuscular blocking agents may be critical for histamine releasing capacity.
