A novel survivable WDM passive optical networks (2008)

We propose a novel survivable wavelength-division multiplexed-passive optical network (WDM-PON) based on an N × N cyclic array waveguide grating (AWG) and reflective semiconductor optical amplifiers (RSOAs). ONUs are grouped and connected with extra connection fibres (CFs). Protection resources are provided mutually in ONU pairs. The characteristics of the proposed survivable WDM-PON and wavelength routing scheme are analyzed. Experiments of 10- Gb/s downstream and 1.25-Gb/s upstream transmission experiments are demonstrated to verify our proposed scheme.
Interleukin-6, a reliable prognostic factor for ischemic stroke. (2014)

The evidence from the present study suggests that IL-6 contributes to determination of severity of ischemic stroke. In addition, IL-6 concentrations affect clinical outcomes in ischemic stroke.
On radial basis functions (2019)

Many sciences and other areas of research and applications from engineering to economics require the approximation of functions that depend on many variables. This can be for a variety of reasons. Sometimes we have a discrete set of data points and we want to find an approximating function that completes this data; another possibility is that precise functions are either not known or it would take too long to compute them explicitly. In this snapshot we want to introduce a particular method of approximation which uses functions called radial basis functions. This method is particularly useful when approximating functions that depend on very many variables. We describe the basic approach to approximation with radial basis functions, including their computation, give several examples of such functions and show some applications.
Metallic Magnetic Superlattices (1992)

Artificially made, ordered material systems are a pillar of late-20th-century advanced technology. In principle, metallic magnetic superlattices—also called magnetic multilayers—should exhibit more new and interesting physical effects than any other artificially made material system. This gives them the potential for many technological advances in information storage and retrieval and in the synthesis of new magnets for a variety of applications.
Low-voltage low-power CMOS design (2016)

Minimal power dissipation is one of the main characteristics of portable devices, smart sensor networks and nodes, medical equipments, etc. The best choice is the sub threshold CMOS regime, where supply voltage is lower than threshold voltage of MOS transistor. In this paper it is shown that in sub threshold CMOS regime, dissipation is influenced by transistor threshold voltage, beside supply voltage and CMOS technology parameters. It is shown that by decreasing threshold voltage the total dissipation increases. An energy efficient design means multiple-threshold CMOS. The analytic model of CMOS inverter dissipation is confirmed with simulations of 1-bit adder in P Spice, with implementation of 90 nm CMOS technology parameters.
Acute respiratory distress syndrome: Low-stretch ventilation improves survival (2000)

In a recent major study, patients with acute respiratory distress syndrome or acute lung injury were randomly assigned to have their respirators set to deliver tidal volumes of either 6 mL/kg or a more-traditional 12 mL/kg. Mortality in the low-tidal-volume group was 31.0%, compared with 39.8% in the traditional-tidal-volume group, a 22% difference (P = .007).
A low-voltage high-swing colpitts VCO with Inherent tapped capacitors based dynamic body bias technique (2017)

A low-voltage high-swing voltage-biased Colpitts voltage-controlled oscillator (VCO) is proposed for wireless applications. A small capacitive voltage divide factor is chosen to enhance the output swing and improve the phase noise performance. To further enhance the negative resistance, and thus decrease the start-up time, the bulk terminals of the gm-boosting transistors are dynamic-biased by the low-swing nodes provided by the inherent tapped capacitors in Colpitts VCOs. Due to the switching operation mode of the gm-boosting transistors and the absence of common-mode nodes for the switching transistors, the flicker noises up-conversion is largely suppressed. Designed in a 0.18-μm CMOS process, the postlayout simulation results show that it provides a phase noise of -127.66 dBc/Hz at 1 MHz offset centered at 3.76 GHz and a figure-of-merit (FoM) of 192.4 dBc/Hz while dissipating 4.71 mW from a 0.6 V supply. The tuning range is 17% (from 3.28 GHz to 3.89 GHz) and the 1/f <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> phase noise corner is only 60 kHz.
Simple power distribution load forecasting method based on fuzzy modelling (2002)

During the last three and a half decades various load forecasting methods have been created. However, these methods cannot forecast future loads in case of severe lack of data, when only few loads are measured in nonconsecutive years. This paper presents two simple methods developed specially to handle such a situation: a simple trending method and a method based on fuzzy modelling. Fuzzy modelling is carried out using a subtractive fuzzy clustering algorithm and recursive least-squares estimator. Both load forecasting methods are illustrated by a numerical example.
The development of assays for the detection of fibrin(ogen)olysis based on COOH-terminal A alpha chain epitopes (1994)

The COOH-terminal two-thirds of the fibrinogen A alpha chain is a substrate for both factor XIIIa and plasmin and is, therefore, a source of structural markers for the clinical detection of fibrin(ogen)olysis. Monoclonal antibodies (MoAbs) that bind to epitopes within this region (F-102, A alpha 563–578; F-103, A alpha 259–276) have been applied towards the development of two sensitive and specific enzyme-linked immunosorbent assays (ELISAs). The first assay, a capture (F-102)-tag (F-103) ELISA, measures plasma fibrinogen molecules whose A alpha chains are intact. The second assay, a solution phase competitive ELISA based on MoAb F-102, quantifies circulating COOH-terminal A alpha chain degradation products (A alpha FDPs), among the earliest peptides released from fibrinogen during plasmin-mediated fragment X formation. This assay features a novel preliminary plasma absorption step on concanavalin A to recover A alpha FDPs (if present in the sample) in a milieu free of immunologically cross-reactive fibrinogen. Both ELISAs use highly purified fibrinogen as the assay standard for quantitation. In control plasmas, circulating A alpha FDPs accounted for less than 2% of their respective intact fibrinogen A alpha chain concentration, suggesting a physiologic low level of proteolysis occurring at the extreme COOH-terminal portion of the molecule. Plasma A alpha FDPs were elevated (2.3% to 7.8% of their respective intact fibrinogen A alpha chain concentration) in a group of plasma from patients with documented, high serum FDPs (21 to 41 micrograms/mL). Application of the two ELISAs to characterize the course of A alpha chain proteolysis during thrombolytic therapy (TIMI phase 1) indicated that A alpha FDPs were a very early marker of the lytic state (detectable 15 minutes after treatment had been initiated), and that streptokinase and recombinant tissue plasminogen activator appeared to produce significantly different A alpha chain degradation profiles.

Comorbid Disease and Cancer: The Need for More Relevant Conceptual Models in Health Services Research (2005)

Theadverseconsequencesofcomorbidityposeamajor clinical challenge in the care of older cancer patients. While the burden of comorbidity is clearly a major prognostic factor for long-term survival, the underlying mechanisms are not well understood. Health services research that focuses on specific comorbidities and their effects in a cancer patient’s clinical trajectory can produce new insights into the optimal diagnosis, treatment, and long-term surveillance of cancer patients with comorbid disease. This information can then be used to design interventions that improve prognosis. We propose a conceptual model of comorbidity and cancer that can guide this research. The model illustrates the potential impact of a specific comorbidity at multiple points of a patient’s clinical trajectory, from cancer detection through diagnosis and treatment. Comorbid illness is a significant concern in patients with cancer. 1,2 For example, patients with severe underlying chronic obstructive pulmonary disease are not good candidates for resection of a lung malignancy, and therefore their chance of cure is decreased. 3,4 Similarly, a diagnosis of congestive heart failure precludes some cancer treatments. 5,6 Comorbid disease is also a competing cause of death. This is particularly true for older patients with cancer, who comprise the majority of new cancers diagnosed.
An efficient power routing technique to resolve the current crowding effect in the power grid structure of gate arrays (2002)

This paper is the first report on the detrimental current crowding effect in the power grid structure of gate arrays. Innovative solutions to the problems are described. The proposed power routing technique utilizes flexible metalization with respect to the power pad locations. The resulting structure improves gate utilization and prevents metal electromigration. The CAD physical design flow for implementation in a 0.5 /spl mu/m CMOS sea-of-gate array is described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

[Characteristics of isolated cardiomyocytes of the left regions of the human heart in hypertrophy]. (1983)

Study of the DNA content in nuclei and of the number of polynuclear cardiomyocytes in the left auricula atrii and the left ventricle wall in the operation and biopsy material of patients with mitral valvular disease showed hypertrophy to be accompanied by polyploidization and division of the nuclei as well as division of cardiomyocytes themselves.
A 94 GHz differential radiometer for observations of diffuse sky emission (1991)

The design and performance of a portable 94 GHz differential radiometer is discussed. The antenna system is an off-axis paraboloid-hyperboloid combination with a field of view of about 50 arcmin. All mirrors are made of carbon fiber coated with silver. Beam switching is obtained by wobbling sinusoidally the primary (parabolic) mirror. This radiometer was used in Antarctica (Italian Base, Terra Nova Bay, −74 S, +164 E) to make measurements to the diffuse sky emission at mm wavelengths. In future, we are also planning to use the antenna, together with a more sensitive detector, to make measurements of the cosmic background radiation anisotropy (CBR).
Motion pattern based video classification using support vector machines (2003)

Semantic classification is an effective approach to the management of vast digital video data. We propose a new semantic classification scheme based on motion patterns. With such a scheme, the motion patterns in video clips can be effectively mapped to semantic conceptions. Motion texture (see Ma, Y.F. and Zhang, H.J., "Motion Texture: A New Representation for Video Content", Technical Report, Microsoft Research, 2001) is employed as motion pattern descriptor, which can be extracted from shots or video clips. By using kernel support vector machines (SVMs), we have devised an optimized multi-class classifier to link low level features with conceptions. Experimental results indicate that our approach is an effective solution for motion pattern based semantic video classification.
Initial adduct formation by 1,4-benzoquinones in liquid ammonia to give 4-amino-4-hydroxycyclohexa-2,5-dienones and 3,6-diamino-3,6-dihydroxycyclohexa-1,4-dienes (1984)

N.m.r. spectra (1H and 13C) of fresh solutions of 1,4-benzoquinone and substituted (mainly chloro-and methyl-)1,4-benzoquinones in liquid ammonia at 240 K correspond to adduct formed by nucleophilic addition to the carbon of the carbonyl group (4-amino-4-hydroxycyclohexa-2,5-dienones). In quinones where the two carbonyl group are not equivalent (namely mono-, 2,6-di-, and tri-chloro and the corresponding methyl-substituted 1,4-benzoquinones) this attack is always at the carbonyl which has the greater number of ortho-substituents. Solutions of 2,3-di-,2,5-di, and tri-chloro-1,4-benzoquinone also show other absorptions which correspond to smaller concentrations of the corresponding diadducts (3,6-diamino-3,6-dihydroxycyclohexa-1,4-dienes).On cooling from 240 to 220 K these latter absorptions intensify at the expense of those due to the monoadducts.The adducts are relatively stable at 220K, persisting for many hours and, in the case of 1,4-benzoquinone itself, for several days. From fresh solutions the initial quinone may be recovered in all cases.
Semantic Web Recommendation application (2012)

This paper focuses on a semantically-enhanced Social Web Recommendation application, called Taste It! Try It! It is a mobile restaurants' review and recommendation application based on a Linked Data source and integrated with a social network. The application is consuming Linked Data (while creating the reviews), producing semantic annotations (about the reviewed entities), and then, querying the gathered data in order to offer personalized recommendations.
Introduction: The Euphoric Politics of Postmodern Barcelona (2012)

Woody Allen's 2008 film Vicky Cristina Barcelona depicts Barcelona as a charming and cosmopolitan city. Foreigners find its fusion of European sophistication and Mediterranean lifestyle irresistible. The city is so appealing that it seems to have engendered the series of sexual encounters, romantic scenes, and artistic impulses experienced by the characters. It is true that, given the empty aestheticism and lack of social significance of his recent films, Allen could have set the movie in, say, Bagdad, and still manage to portray a group of affluent individuals only worried about their sexual dissatisfaction and their cultural taste. However, Barcelona seemed to serve especially well as a delightful and nonconflictive setting.
Method for providing live content during playback of recorded streams in personal video recorders (2006)

Personal video recorders provide the facility of recording live broadcast streams thus users can replay their recordings whenever they want. However, during playback of those recorded streams, users are isolated from the live content (e.g., latest news) in which they might be interested. In this paper, we propose an MPEG-2 transport stream compatible method which can inform the user about live content that's in user interest area during playback. The method-specific structures, algorithms and an implementation on a Linux platform are presented in the paper
A high-throughput memory-based VLC decoder with codeword boundary prediction (2000)

In this paper, we present a high-throughput memory-based VLC decoder with codeword boundary prediction. The required information for prediction is added to the proposed branch models. Based on an efficient scheme, these branch models and the Huffman tree structure are mapped onto memory modules. Taking the prediction information, the decompression scheme can determine the codeword length before the decoding procedure is completed. Therefore, a parallel-processor architecture can be applied to the VLC decoder to enhance the system performance. With a clock rate of 100 MHz, a dual-processor decoding process can achieve decompression rate up to 72.5 Msymbols/s on the average. Consequently, the proposed VLC decompression scheme meets the requirements of current and advanced multimedia applications.

Influence of Altered Gut Microbiota Composition on Aging and Aging-Related Diseases (2018)

The gut microbiota forms a large community that coexists with all species, including humans and rodents. Genome projects have been conducted by many researchers in nearly every country to better understand and treat diseases that lead to death in humans. However, the gut microbiota is known as a "second genome" because it includes microbes, genomic DNA, proteins, and metabolites. A large number of studies have revealed the importance of the gut microbiota. In elderly people, the diversity of the gut microbiota is reduced and there is an increased incidence of degenerative diseases, including Alzheimer's and Parkinson's, and decreased cognitive and memory functions. However, the administration of pre/probiotics can help to improve the symptoms of these diseases. Therefore, we believe that the gut microbiota is important for maintaining homeostasis and diversity, as well as for avoiding gastrointestinal tract-derived diseases and improving health in the elderly population.
Onions: A Source of Unique Dietary Flavonoids (2007)

Onion bulbs (Allium cepa L.) are among the richest sources of dietary flavonoids and contribute to a large extent to the overall intake of flavonoids. This review includes a compilation of the existing qualitative and quantitative information about flavonoids reported to occur in onion bulbs, including NMR spectroscopic evidence used for structural characterization. In addition, a summary is given to index onion cultivars according to their content of flavonoids measured as quercetin. Only compounds belonging to the flavonols, the anthocyanins, and the dihydroflavonols have been reported to occur in onion bulbs. Yellow onions contain 270–1187 mg of flavonols per kilogram of fresh weight (FW), whereas red onions contain 415–1917 mg of flavonols per kilogram of FW. Flavonols are the predominant pigments of onions. At least 25 different flavonols have been characterized, and quercetin derivatives are the most important ones in all onion cultivars. Their glycosyl moieties are almost exclusively glucose, which is mainly attached to the 4′, 3, and/or 7-positions of the aglycones. Quercetin 4′-glucoside and quercetin 3,4′-diglucoside are in most cases reported as the main flavonols in recent literature. Analogous derivatives of kaempferol and isorhamnetin have been identified as minor pigments. Recent reports indicate that the outer dry layers of onion bulbs contain oligomeric structures of quercetin in addition to condensation products of quercetin and protocatechuic acid. The anthocyanins of red onions are mainly cyanidin glucosides acylated with malonic acid or nonacylated. Some of these pigments facilitate unique structural features like 4′-glycosylation and unusual substitution patterns of sugar moieties. Altogether at least 25 different anthocyanins have been reported from red onions, including two novel 5-carboxypyranocyanidin-derivatives. The quantitative content of anthocyanins in some red onion cultivars has been reported to be approximately 10% of the total flavonoid content or 39–240 mg kg−1 FW. The dihydroflavonol taxifolin and its 3-, 7-, and 4′-glucosides have been identified in onions. Although the structural diversity of dihydroflavonols characterized from onions is restricted compared with the wide structural assortment of flavonols and anthocyanins identified, they may occur at high concentrations in some cultivars. From bulbs of the cultivar “Tropea”, 5.9 mg of taxifolin 7-glucoside and 98.1 mg of taxifolin have been isolated per kilogram of FW.
