Biodiversity and application of microalgae (1996)

The algae are a polyphyletic, artificial assemblage of O2-evolving, photosynthetic organisms (and secondarily nonphotosynthetic evolutionary descendants) that includes seaweeds (macroalgae) and a highly diverse group of microorganisms known as microalgae. Phycology, the study of algae, developed historically as a discipline focused on the morphological, physiological and ecological similarities of the subject organisms, including the prokaryotic bluegreen algae (cyanobacteria) and prochlorophytes. Eukaryotic algal groups represent at least five distinct evolutionary lineages, some of which include protists traditionally recognized as fungi and protozoa. Ubiquitous in marine, freshwater and terrestrial habitats and possessing broad biochemical diversity, the number of algal species has been estimated at between one and ten million, most of which are microalgae. The implied biochemical diversity is the basis for many biotechnological and industrial applications.
Combining Classifiers and Learning Mixture-of-Experts (2009)

Expert combination is a classic strategy that has been widely used in various problem solving tasks. A team of individuals with diverse and complementary skills tackle a task jointly such that a performance better than any single individual can make is achieved via integrating the strengths of individuals. Started from the late 1980’ in the handwritten character recognition literature, studies have been made on combining multiple classifiers. Also from the early 1990’ in the fields of neural networks and machine learning, efforts have been made under the name of ensemble learning or mixture of experts on how to learn jointly a mixture of experts (parametric models) and a combining strategy for integrating them in an optimal sense. The article aims at a general sketch of two streams of studies, not only with a re-elaboration of essential tasks, basic ingredients, and typical combining rules, but also with a general combination framework (especially one concise and more useful one-parameter modulated special case, called a-integration) suggested to unify a number of typical classifier combination rules and several mixture based learning models, as well as max rule and min rule used in the literature on fuzzy system.
An acoustic sensor based novel method for 2D localization of a robot in a structured environment (2015)

Differences in locality in a structured environment cause variations in the reflection of an emitted acoustic wave. This paper exploits the above principle to propose a novel method of robot localization on a 2D map. The work brings novelty by using a simple acoustic emitter and a receiver for robot localization as opposed to exteroceptive sensors such as lasers, cameras, sonars and electromagnetic sensors which are conventionally used. This method requires only one sound emitter and a receiver in addition to odometry data to assist 2D localization of any mobile platform located in a pre-explored structured environment. The paper demonstrates the method through simulation by using Finite Element Analysis to solve the Helmholtz partial differential equation of acoustic wave propagation on a 2D map, and using a particle filter to correct the odometry through acoustic observations. Results show that the proposed method can effectively correct the odometry of a mobile platform in a structured environment. When compared with conventional exteroceptive sensors, compact installation and cost effectiveness come as practical advantages when implementing this method.
Glass transition temperatures in binary polymer blends (2008)

Abstract Knowledge of the glass transition temperatures ( T g s) as function of composition reflects miscibility (or lack of it) and is decisive for virtually all properties of polymer‐based materials. In this article, we analyze single blend‐average and effective T g s of miscible polymer blends in full concentration ranges. Shortcomings of the extant equations are discussed to support the need for an alternative. Focusing on the deviation from a linear relationship, defined as Δ T g = T g − φ 1 T g,1 − φ 2 T g,2 (where φ i and T g, i are, respectively, the weight fraction and the T g of the i ‐th component), a recently proposed equation for the blend T g as a function of composition is tested extensively. This equation is simple; a quadratic polynomial centered around 2φ 1 − 1 = 0 is defined to represent deviations from linearity, and up to three parameters are used. The number of parameters needed to describe the experimental data, along with their magnitude and sign, provide a measure of the system complexity. For most binary polymer systems tested, the results obtained with the new equation are better than those attained from existing T g equations. The key parameter of the equation a 0 is related to parameters commonly used to represent intersegmental interactions and miscibility in binary polymer blends. © 2008 Wiley Periodicals, Inc.

Purification and some properties of a novel ethylene-forming enzyme produced by Penicillium digitatum (1989)

A novel ethylene-forming enzyme that forms ethylene from α-ketoglutarate was purified from the cell-free extract of Penicillium digitatum IFO 9372. The purified enzyme was confirmed to be homogenous on polyacrylamide disc gel electrophoresis, and the molecular weight of the enzyme consisting of a single polypeptide was estimated to be about 42 kDa by gel filtration column chromatography and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The presence of α-ketoglutarate, l-arginine, ferrous ion, dithiothreitol and oxygen were essential for the enzyme reaction. Substrate and cofactor specificity of the enzyme was highly specific for α-ketoglutarate and l-arginine, respectively. Some properties of the purified enzyme were surveyed and compared with those of the ethylene-forming system in higher-plants.
Frequency of ApoB and ApoE Gene Mutations as Causes of Hypobetalipoproteinemia in the Framingham Offspring Population (1998)

Hypobetalipoproteinemia (HBLP) is characterized by plasma concentrations of apolipoprotein B (apoB) and low density lipoprotein cholesterol (LDL-C) below the fifth percentile. Some forms of HBLP have been shown to be due to truncated forms of apoB-100. A total of 3873 subjects participating in the Framingham Offspring Study had LDL-C levels measured every 4 to 5 years throughout a 25-year period. Seventy-five subjects were identified with persistent HBLP, defined as an LDL-C <70 mg/dL on at least 2 observations, for a prevalence of 1.9% in this population. Compared with subjects with LDL- C >/=70 mg/dL, subjects with HBLP had significantly lower mean levels of total cholesterol, LDL-C, triglyceride, and apoB; higher levels of high density lipoprotein cholesterol; and a higher prevalence of the E2/E3 genotype: 38.7% versus 10.9% (P<0.001). Men with HBLP had a larger mean LDL particle size than did men with an LDL- C >/=70 mg/dL. One individual had a truncated apoB as a cause of HBLP, for a prevalence of 0.03%. Medical causes of HBLP included 2 cases of Crohn's disease, 1 of hemochromatosis, and 1 of hepatitis. Three subjects with HBLP developed coronary heart disease, for an incidence of 4% compared with 5% in those with an LDL- C >/=70 mg/dL (P=NS). The incidence of cancer was 8% in those with HBLP compared with 4% in those with an LDL-C >/=70 mg/dL (P=0.21). In conclusion, a truncated apoB was a rare cause of HBLP, whereas the E2/E3 genotype was a much more common cause. A large prospective study is needed to evaluate the incidence of cancer and atherosclerosis in subjects with HBLP.

Osmotic deswelling of weakly charged poly(acrylic acid) solutions and gels (1995)

Abstract The osmotic pressure of weakly charged aqueous poly(acrylic acid) (PAA) solutions and the swelling pressure PAA gels were studied by osmotic deswelling at different degrees of ionization (α). In solution, the osmotic pressure was found to scale linearly with concentration, whereas the scaling power of the swelling pressure of gels was higher (1.66). The effect of the ionization degree on the osmotic coefficient in PAA solutions was in agreement with the theory of Borue and Erukhimovich [ Macromolecules , 21 , 3240 (1988)]. Ionization increases the swelling capacity of the PAA gels until a plateau is reached at about 35% neutralization. The concentration at equilibrium swelling scales as C e ∼ α −0.6 . The contribution of the network to the gel swelling pressure is evaluated by subtracting the osmotic pressure of the polymer solution at the same concentration and degree of ionization. In swollen gels the extended network opposes swelling. As the gel is osmotically deswelled, a state of zero network pressure exists at a certain concentration, below which the network elasticity favors swelling. The crossover concentration shifts to lower values as the degrees of ionization increases. © 1995 John Wiley & Sons, Inc.

Dual-beam structured light vision system for 3D coordinates measurement (2008)

Recognition and identification of weld environment and seam dimensional position by computer vision is a key technology for developing advanced autonomous welding robot. In this paper, based on the robot laser curve seam tracking background we present our dual-beam structured light system that generates richer information than obtained only from one structured light system. Then the orthogonal Zernike moments edge detection is adopted to localize the centre of the light stripe. The obtained centre precision is subpixel. At the same time, the calibration of the CCD camera and the dual beam structured light is given. In the end, the application of the proposed system is shown and experiments have been implemented and results show that the approach is feasible.

Task Scheduling with Load Balancing on Automotive Multicore ECUs (2018)

In order to achieve greater performance with low power dissipation at moderate clock rate which is required to reduce the electromagnetic interference and compatibility issues with high speed processors, multicore processors have been implemented in automotive electronic control units(ECUs). Multicore processors enable the automobile manufacturers to add more functionality into one ECU rather than integrating more number of single functional ECUs. With the introduction of multicore processors in automotive ECUs, complexity in the design, development, and verification of the applications software have been increased tremendously. Even though both the hardware and software have parallelizability, there are certain design challenges such as: integrating various application software and scheduling the application tasks to balance the load across the cores. It requires to sequencing threads within the chained tasks, segregating those into thread sets and allocating to the available processing cores. In this paper, we address the problem of clustering numerous task threads and allocating them on multiple identical cores.We present a low-complexity modified heuristic algorithm to partition and build thread sets and map those on to cores so as to balance the load across the cores. It is observed that, minimum average load of the total load is distributed to each core to achieve a balanced load with task scheduling in simulating environment. The performance of the algorithm on dual core, tri core and quad core processors have been verified and compared to the same on single core processor.
Environmentally Acceptable Corrosion Inhibitor for Filter-Cake Removal System (2013)

Abstract The production of hydrocarbons with minimum drawdown pressure requires removal of the filter cake formed during overbalanced drilling. In such an operation, the delayed-breaker system used consists of an acid precursor that reacts slowly with water in the carrier brine and releases a strong organic acid, which dissolves the soluble part of the filter cake. However, exposure of downhole tools to acid at elevated temperature and pressure conditions can exacerbate the corrosion potential. Tool corrosion can lead to costly delays related to mechanical failure and workover operations. Corrosion inhibitors are used to help minimize the impact of acids on metals. Stringent environmental regulations have increased industry emphasis on environmentally acceptable corrosion inhibitors, which not only provide good corrosion protection, but can be disposed of easily with minimal impact on the environment. As an example, North Sea environmental regulations are considered the benchmark for ecotoxicity and biodegradability parameters. This study describes the corrosion protection potential of different food grade products. Experiments were conducted at 150 and 200°F using steel coupons and varying exposure times. Corrosion loss for different food grade products was less than 0.05 lbm/ft2 after 24 hr. No signs of pitting or crevice formation were observed on the metal coupons. After initial testing, products were screened for further investigation. Corrosion experiments conducted on steel grade metal with a food grade product from the legume family at 150°F resulted in a corrosion loss of 0.02 lbm/ft2 after seven days. Addition of corrosion inhibitor intensifier (CII), even at lower concentrations, enhanced the performance of inhibitors and made them suitable for higher-temperature applications. Corrosion experiments were also performed in the presence of calcium carbonate particles to simulate filter cake. Good inhibition was observed. A comparison of different food grade products applied as corrosion inhibitors and the practical limitations of these products is presented in this paper.
A Miniaturized, No-Moving-Parts Raman Spectrometer (1993)

A solid-state acousto-optic tunable filter (AOTF) is combined with krypton laser excitation (647 nm), holographic Raman filters, and photon-counting silicon avalanche photodiode (APD) detection to construct a miniaturized Raman spectrometer with no moving parts. The physically compact AOTF and the highly integrated APD provide a rugged, digitally controlled spectrometer of moderate spectral resolution and with a footprint comparable in size to a laboratory notebook. Instrument design details are considered and representative spectra are reported. Potential areas of application for this prototype Raman spectrometer are also discussed.
Measurement of phase-matching spectral phase by nonlinear spectral interferometry (2011)

We experimentally measured the phase-matching spectral phase of chirped quasi-phase matched gratings for the first time (to the best of our knowledge), which is essential in determining the nonlinear signal shape and domain distributions.
Low-Power Image Compression for Wireless Capsule Endoscopy (2007)

In the paper image compression algorithm suitable for wireless capsule endoscopy is proposed. In general, image compression is the best way to decrease the communication bandwidth and save the transmitting power. However due to power limitation and small size conditions traditional image compression techniques are not appropriate and dedicated ones are necessary. The proposed algorithm is based on integer version of discrete cosine transform (DCT) and entropy Huffman coder. Thanks to integer DCT application it has low complexity and power consumption. Additionally, the algorithm can provide lossless compression as well as high-quality lossy compression.
Buprenorphine vs Methadone Maintenance Treatment for Concurrent Opioid Dependence and Cocaine Abuse (1997)

The results support the superiority of higher daily buprenorphine and methadone maintenance doses vs lower doses for reducing illicit opioid use, but the results do not support the superiority of buprenorphine compared with methadone for reducing cocaine use.
Periodic binary sequences with very good autocorrelation properties (1985)

Computer searches were performed using both an 8086 microprocessor and a Cyber 750 mainframe to find repeated binary phase coded waveforms with very good matched and mismatched autocorrelation properties. The best results for every period up to 64 are given. Sequences with optimal peak sidelobes were discovered for each of these periods. These sequences have extensive applications in radar and communications, particularly in situations when there are very unfavorable signal-to-noise ratios. The best sequence of period 64 when processed using a mismatched filter giving no sidelobes has a reduction in the main lobe of less than 0.23 dB.
Estrogenic Potency of Food-Packaging-Associated Plasticizers and Antioxidants As Detected in ERα and ERβ Reporter Gene Cell Lines (2006)

This study presents the estrogenic potency of 21 food-packaging-associated compounds determined for the first time, using two transfected U2-OS (human osteoblasts devoid of endogenous estrogen receptors) estrogen receptor (ER) alpha and beta cell lines. Six plasticizers and three antioxidants were slightly estrogenic in the ERα cells. The model compounds bisphenol A and nonylphenol, one plasticizer [tris(2-ethylhexyl)trimellitate (TEHTM)], and two antioxidants (propyl gallate and butylated hydroxyanisole) were estrogenic in both ERα and ERβ cells. Compared to estradiol (E2), these compounds appeared to be relatively more estrogenic in the ERβ cells than in the ERα cells. Three sorbitol-based plasticizers activated neither ERα nor ERβ and may be good replacements of existing plasticizers. All responses were additive with the response of E2. This indicates that they may contribute to the total effects of the pool of estrogenic compounds humans are exposed to. The estrogenic potencies of these compounds, together with the suggested beneficial effect of ERβ-mediated responses and adverse ERα-mediated effects, support the importance of detecting characteristics for ERα and ERβ response separately in independent models, as done in the present study.

Treatment of Parkinson's disease with levodopa and Ro 4‐4602 (1971)

The authors report their experience over a 14 month period in the treatment of 20 parkinsonian patients with the combination of levodopa and an inhibitor of peripheral dopa decarboxylase, Ro 4‐4602. The results obtained are comparable to those previously reported from the same center with levodopa alone and, in fact, appear to offer distinct advantages. The average daily dose of levodopa required for satisfactory results (after 3 months of treatment) was reduced from 4.S Gm. of levodopa alone to SOD mg. on the combination. The maximum daily dose of Ro 4‐4602 recommended to obtain this effect is 200 mg.
P300 and Tracking Difficulty: Evidence For Multiple Resources in Dual‐Task Performance (1980)

ABSTRACT Subjects performed a visual tracking task while performing a concurrent task in which tones were covertly counted. The P300 component of the event‐related potentials elicited by the tones was examined to determine the extent to which its amplitude was affected by variations in the forcing‐function bandwidth, or difficulty, of the tracking task. P300 decreased in magnitude when tones were counted in conjunction with the performance of the tracking task, relative to a single‐task counting condition. Increasing tracking difficulty failed to reduce P300 amplitude further. A second experiment obviated the possibility that movement‐related potentials caused the P300 attenuation resulting from the introduction of the tracking task. In Experiment 3, subjects performed a reaction time task in conjunction with tracking in order to establish the validity of the tracking difficulty manipulation. The results are interpreted in terms of a theory of functionally‐specific processing resources.
