Improved photovoltaic MPPT algorithm adapted for unstable atmospheric conditions and partial shading (2009)

In this paper, we present and implement an improved maximum power point tracking (MPPT) algorithm for photovoltaic (PV) applications. The proposed algorithm incorporates an online current measurement and periodic interrupts to address certain challenges associated with rapidly changing insolation and partial shading. A new rule for updating the adaptive step-size is introduced for improving dynamic and steady-state responses. This rule exploits the first and second derivatives of power as a function of duty-cycle. The algorithm is implemented on a micro-controller, and the technical issues concerning the hardware design and implementation are discussed. Finally, we present both simulation and experimental results, under different irradiation schemes.
Combination external beam radiation and brachytherapy boost with androgen deprivation for treatment of intermediate‐risk prostate cancer (2011)

In a cooperative setting, combination of EBRT and transperineal prostate brachytherapy boost plus ADT resulted in excellent DFS with acceptable late toxicity for patients with intermediate-risk prostate cancer.
Winner of the 1988 NAASO Young Investigator Award. Regulation of fat cell adenylate cyclase in young Zucker (fa/fa) rats: alterations in GTP sensitivity of adenosine A1 mediated inhibition. (1990)

Lipolysis in rat adipocytes is controlled by the hormonally mediated stimulation and inhibition of adenylate cyclase. This dual regulation involves stimulatory (Gs) and inhibitory (Gi) GTP-binding proteins which control cAMP production in a GTP dependent manner. Adenosine, acting via the A1 receptor-Gi complex provides tonic regulation of adenylate cyclase and lipolysis in rat adipocytes. Adipocytes prepared from young obese Zucker (fa/fa) rats exhibit less stimulation (or greater inhibition) in response to adenosine deaminase, alone or in combination with lipolytic hormones, as compared with their lean littermates. Adenylate cyclase, measured in membranes prepared from obese adipocytes, showed decreased sensitivity to activation by low concentrations of GTP and was not inhibited by higher concentrations of the guanine nucleotide which, in lean control rats results in a biphasic activity curve. Adenosine A1 receptor binding, measured in these same membranes, demonstrated an increased sensitivity to activation by the GTP analogue, guanylyl imidodiphosphate. The presence of the analogue results in the dissociation of the receptor-Gi complex and conversion to the low affinity form in a greater proportion of receptors in the obese membranes. These results are consistent with an increased sensitivity to adenosine mediated inhibition of adenylate cyclase and lipolysis in the fat cells of the young obese (fa/fa) Zucker rat.
Miniature wireless photoplethysmography devices: integration in garments and test measurements (2012)

Wireless PPG devices were developed and embedded in everyday clothes (bandage, scarf, cycling glove and wrist strap) to monitor cardiovascular state of free-moving persons. The corresponding software for measurements also has been developed and tested in laboratory. Real-time measurements of PPG signals were taken in parallel with a professional ECG reference device, and high correlation was demonstrated.

This position paper first briefly reviews the basic concepts about cognitive radio (CR) technology, and then discusses the differentiating features of CR and the fundamental theories or principles behind CR, especially from the artificial intelligence and machine learning perspective. A survey on the state-of-the-art development on CR testbeds around the world is presented, which indicates the trend of future development. A lot of emerging research topics in various areas are also discussed, which could be further investigated in an innovative CR approach.
Placer Mining Silt and its Relation to Salmon and Trout on the Pacific Coast (1940)

Renewed activity in the placer gold mining country of the Pacific Coast States has raised the question of how much harm silt does to salmon and trout. The effect silt may have on migrating adult fish, on the selection of spawning places, and on the survival of fish food, is discussed. The conclusion is drawn that silt, whether from placer mining or natural erosion, is harmful to salmon and trout if it is heavy enough to form a layer on the stream bottom or if it persists during periods between floods.
Existence of Periodic Solutions to a Class of Second-order Neutral Differential Difference Equations (2003)

By means of variational structure and critical point theory, we give some criteria for the existence of periodic solutions to a class of second-order neutral differential difference equations as the following type x(t-τ)-x(t-τ)+f(t, x(t), x(t-τ), x(t-2τ))=0 with the boundary value condition x(0)=x(2kτ), x(0)=x(2kτ) where k is a given positive integer and τ is a positive number.
La investigaciÓn sobre la primera teología cristiana. Significado y alcance de la obra de A. Orbe (2004)

This article sums up the unique figure and the enormous literary production of Fr. A. Orbe, one of the most distinguished contemporary catholic scholars of the beginnings of Christian theology, been professor at the Gregorian University of Rome all his life. After a brief biographical browse, his methodological contribution to the readings of the theological works from the first centuries is evaluated. Analyzing successively the various contents of his research and the main works which came out of his pen, the wide range and the relevance his studies have to ancient philosophy studies, biblical exegesis and, as a consequence, dogmatics, is emphasized. His Christology studies of the first and second centuries, the anthropology of St. Ireneus and the Valentinian Studies are particularly worthy of interest for any subsequent research. It is not to forget - in the way they give us a more complete image of the author - his multiple and rich spiritual works.

Action that goes beyond the simple transfer of information for being a complex activity, which requires for its exercise the understanding of the educational phenomenon with holistic instructional planning vision as the north, of participation with mutual respect despite different opinions (Example in the directed discussion strategy), based on the seven basic principles of complex thinking.
Simultaneous motion parameter estimation and image segmentation using the EM algorithm (2002)

We propose and investigate a method to simultaneously segment an image in a sequence of images into regions of uncovered background, moving, and stationary pixels and estimate parameters of interest for the various regions. The basis of our method is the expectation-maximization (EM) algorithm for maximum-likelihood estimation. We view the intensity difference between image frames as the incomplete data and the intensity difference with the region identifier as the complete data.
Synergistic Interaction in the adsorbed mixed surfactants film of Sodium Dodecyl Sulfate and Cocamidopropyl Betaine on Liquid – Air Interfacial (2016)

In the present work, the critical micelle concentration (CMC) of the solution of Sodium dodecyl sulfate (SDS) as anionic surfactant, Cocamidopropyl Betaine (CAPB) as amphoteric surfactant, and their mixture have been determined using surface tension and conductivity measurements at a temperature range 293 -323 K. The adsorption and thermodynamic micellization parameters (?G?m, ?G?ads, ?max ,Amin,?cmc ) for individual surfactants was calculated. Rosen model which is focuses on the adsorbed mixed surfactant film at the air/solution interface was used to calculate the interaction parameter ( ?? ) at the interface and the activity coefficients g1 and g2. The results indicate that the CMC of the individual surfactants was affected by the temperature at the temperature range studied. Also, the results indicate a synergistic effect present at the air – solution mixed film of surfactants.
Erythrocytes transfused into patients with SLE and haemolytic anaemia lose complement receptor type 1 from their cell surface. (1987)

Erythrocyte complement receptor type 1 (CR1) shows a numerical deficiency in patients with SLE and with haemolytic anaemias. This receptor is a cofactor for the enzymatic degradation of C3b and is believed to play a role in the transport of immune complexes from the circulation to the reticulo-endothelial system. Erythrocyte CR1 was enumerated on cells which had been transfused into patients with SLE and haemolytic anaemias. In three patients with active disease up to 60% of CR1 was lost from erythrocytes during 5 days after blood transfusion and up to 410 molecules of C3 were deposited on these cells. These are the first in vivo data showing that CR1 may be lost from circulating erythrocytes. This acquired deficiency of CR1 on erythrocytes may have pathological consequences in patients with SLE.
Genome-Wide Analysis Reveals a Highly Diverse CD8 T Cell Response to Murine Cytomegalovirus (2006)

Human CMV establishes a lifelong latent infection in the majority of people worldwide. Although most infections are asymptomatic, immunocompetent hosts devote an extraordinary amount of immune resources to virus control. To increase our understanding of CMV immunobiology in an animal model, we used a genomic approach to comprehensively map the C57BL/6 CD8 T cell response to murine CMV (MCMV). Responses to 27 viral proteins were detectable directly ex vivo, the most diverse CD8 T cell response yet described within an individual animal. Twenty-four peptide epitopes were mapped from 18 Ags, which together account for most of the MCMV-specific response. Most Ags were from genes expressed at early times, after viral genes that interfere with Ag presentation are expressed, consistent with the hypothesis that the CD8 T cell response to MCMV is largely driven by cross-presented Ag. Titration of peptide epitopes in a direct ex vivo intracellular cytokine staining assay revealed a wide range of functional avidities, with no obvious correlation between functional avidity and the strength of the response. The immunodominance hierarchy varied only slightly between mice and between experiments. However, H-2(b)-expressing mice with different genetic backgrounds responded preferentially to different epitopes, indicating that non-MHC-encoded factors contribute to immunodominance in the CD8 T cell response to MCMV.
The characteristics and decodability of the Universal Product Code symbol (1975)

Optical scanning components of supermarket systems require machine-readable code. The need for industry-wide cooperation and standardization of a code and symbol was shown. The sources of decoding error in printed optical codes were discussed and a class of codes, the (n, k ) codes, relatively resistant to error, were presented. The UPC code is a (7, 2) code. The UPC code and a method of decoding it were described. Decodability depends on several parameters; their quantitative relationships and effects upon decodability are found in another paper.
Uranyl−Peroxide Interactions Favor Nanocluster Self-Assembly (2009)

Uranyl peroxide polyhedra are known to self-assemble into complex closed clusters with fullerene and other topologies containing as many as 60 polyhedra. Here clusters containing 20 uranyl pentagonal triperoxides have been isolated and characterized that assume the smallest possible fullerene topology consisting only of 12 pentagons. Oxalate has been used to crystallize fragments of larger uranyl peroxide clusters, and these fragments and other known structures indicate that the U-O(2)-U dihedral angle is inherently bent. Such bending is thought to be essential in directing the self-assembly of uranyl peroxide polyhedra into closed clusters.

A New Format of Streaming Media for Teaching (2012)

The streaming media for teaching has some special characteristics that are different from common VODs in entertainment applications, and also, the similar circumstances appear between common desktop computers and portable devices with capacitive touch display such as iPad. Therefore it is necessary to develop a new media format for teaching. Based on the ASF format, a new Streaming Media format for Teaching (TSM format) is proposed in this paper. TSM is more suitable for playing on portable devices that has capability of touch display. Several scenarios are selected to experiment TSM's features includes interface and controllers. Experiments show the proposed format is more reasonable, accurate and convenient for processing and playing media for education.
Flexible Fiber and Fabric Batteries (2018)

Abstract The rapid development of wearable electronics requires developing flexible and efficient energy storage systems. To this end, novel flexible fiber and fabric batteries attract increasing attention due to their combined superiorities in flexibility, weavability, and miniaturization compared with conventional bulky structures. Herein, the recent progress in the electrode fabrication, structure design, and battery performance of fiber and fabric batteries is summarized, and the possibility of battery textiles, challenges, and future directions to satisfy the requirement of the next‐generation flexible energy storage systems is also highlighted.
Altered lipoprotein metabolism in transgenic mice expressing low levels of a human receptor-binding-defective apolipoprotein E variant. (1994)

Transgenic mouse lines were produced that expressed low levels of a receptor-binding-defective variant of human apolipoprotein (apo) E, apoE(Arg112, Cys142). In transgenic mice, the human apoE was produced only by the kidney, whereas endogenous mouse apoE was produced mainly by the liver. The plasma concentration of the transgenic protein was about half that of endogenous apoE. The expression of transgenic apoE did not affect total plasma cholesterol and triglyceride levels, but the distribution of the human variant differed from that of endogenous apoE in the intermediate size and density range, where the transgenic protein accumulated selectively. Immunoblots of agarose gels of lipoprotein fractions showed that the transgenic protein occurred primarily on large alpha-migrating particles (HDL1). This phenomenon was not observed in transgenic mice expressing normal human apoE-3, which distributed like endogenous apoE, suggesting that the defective apoE variant perturbed HDL1 metabolism. In mice fed a high-fat, high-cholesterol diet, the transgenic apoE associated primarily with the apoB-containing lipoproteins. A significantly higher increase in very low density lipoprotein cholesterol was observed in fat-fed transgenics compared to fat-fed nontransgenic mice, suggesting a metabolic perturbation of apoB-containing lipoproteins. Thus, the receptor-binding-defective variant, apoE(Arg112, Cys142), expressed at low levels by the kidney, alters lipoprotein metabolism in transgenic mice, presumably by interfering with apoE-mediated removal of the lipoproteins from circulation.

Noise Suppression using a Perceptual Model for Wideband Speech Signals (2002)

An insulin mediator preparation was obtained from rat hepatocytes which had been treated with insulin. This preparation inhibited adenylate cyclase activity. It stimulated the activity of homogeneous preparations of both the cytosolic and membrane-bound forms of rat liver cyclic GMP-activated cyclic AMP phosphodiesterase. It failed to activate homogeneous preparations of both the peripheral plasma membrane and 'dense-vesicle' cyclic AMP phosphodiesterases. The insulin mediator preparation stimulated cyclic GMP-activated cyclic AMP phosphodiesterase activity in a dose-dependent fashion with a hill coefficient of 0.46. Insulin caused the dose-dependent production of mediator activity in intact hepatocytes with a Ka of 9 pM, although concentrations of insulin greater than 10 nM progressively reduced stimulatory activity.
Adaptive Naïve Bayesian Anti-Spam Engine (2007)

The problem of spam has been seriously troubling the Internet community during the last few years and currently reached an alarming scale. Observations made at CERN (European Organization for Nuclear Research located in Geneva, Switzerland) show that spam mails can constitute up to 75% of daily SMTP traffic. A naïve Bayesian classifier based on a Bag Of Words representation of an email is widely used to stop this unwanted flood as it combines good performance with simplicity of the training and classification processes. However, facing the constantly changing patterns of spam, it is necessary to assure online adaptability of the classifier. This work proposes combining such a classifier with another NBC (naïve Bayesian classifier) based on pairs of adjacent words. Only the latter will be retrained with examples of spam reported by users. Tests are performed on considerable sets of mails both from public spam archives and CERN mailboxes. They suggest that this architecture can increase spam recall without affecting the classifier precision as it happens when only the NBC based on single words is retrained.
Preparation of trichlorosilane from hydrogenation of silicon tetrachloride in thermal plasma (2010)

A new method of producing trichlorosilane by hydrogenation of silicon tetrachloride with assistance of DC charged thermo-plasma was proposed. We have studied the dependence of degree of disassociation and ionization of hydrogen on temperature, as well as the function of heat capacity, via which the optimal volume and H2: SiCl4 molar ratio were confirmed. A DC power of 50 kW was equipped and the highest yield of trichlorosilane was above 70%, with an average yield about 60% and minimum unit energy expenditure about 3.2 kWh/kg for SiHCl3. This process is possible to be industrialized.
Spectral Sensing of Adaptive Frequency Hopping signal for Cognitive Radio (2008)

The issue of dynamic spectrum scene analysis in any cognitive radio network becomes extremely complex when low probability of intercept, spread spectrum systems are present in environment. The detection and estimation become more complex if frequency hopping spread spectrum is adaptive in nature. In this paper, we propose two phase approach for detection and estimation of frequency hoping signals. Polyphase filter bank has been proposed as the architecture of choice for detection phase to efficiently detect the presence of frequency hopping signal. Based on the modeling of frequency hopping signal it can be shown that parametric methods of line spectral analysis are well suited for estimation of frequency hopping signals if the issues of order estimation and time localization are resolved. An algorithm using line spectra parameter estimation and wavelet based transient detection has been proposed which resolves above issues in computationally efficient manner suitable for implementation in cognitive radio. The simulations show promising results proving that adaptive frequency hopping signals can be detected and demodulated in a non cooperative context, even at a very low signal to noise ratio in real time.
[Analysis of patients with middle lobe and lingular syndrome complicated with nontuberculous mycobacterosis, chronic sinusitis, or bronchopulmonary tuberculosis]. (2001)

The clinical characteristics and chest CT scan findings in 77 cases of middle lobe and lingular syndrome, many of which were complicated with nontuberculous mycobacteriosis (21 cases, 27.3%), chronic sinusitis (16, 20.8%), or bronchopulmonary tuberculosis (11, 14.3%) are reported. Sixteen (76.2%) cases complicated with nontuberculous mycobacteriosis and 14 (87.5%) cases complicated with chronic sinusitis had granular shadows with dilated bronchi of both middle lobe and lingular in their chest CT scans. Granular shadows with a thickening of the bronchial wall or dilated bronchi were common characteristics of the chest CT scans of the patients with nontuberculous mycobacteriosis. However, cicatrization atelectasis of either middle lobe or lingular was the most common finding in patients with bronchopulmonary tuberculosis.
