Using dynamic sets to reduce the aggregate latency of data access (1997)

Many users of large distributed systems are plagued by high latency when accessing remote data. Latency is particularly problematic for the critical application of search and retrieval, which tends to access many objects and may suffer a long wait for each object accessed. Existing techniques like caching, inferential prefetching, and explicit prefetching are not suited to search, are ineffective at reducing latency for search applications, or greatly increase the complexity of the programming model. This dissertation shows that extending the file system interface to support a new abstraction called dynamic sets can address the problem of latency for search without incurring the penalties of the other techniques. A dynamic set is a lightweight and transitory collection of objects with well-defined semantics. An application creates a dynamic set on-demand to hold the objects it wishes to process. Adding dynamic sets to the system&apos;s interface results in two benefits. First, creation of a...

Chia Seed ( <i>Salvia hispanica</i> L.) as a Source of Proteins and Bioactive Peptides with Health Benefits: A Review (2019)

The consumption of chia seed (Salvia hispanica L.) has increased in recent years due its high content of omega-3 fatty acids and dietary fiber. This seed also has a high concentration of proteins and essential amino acids, becoming a promising source of bioactive peptides. The objective of this review was to identify the composition and the beneficial effects of chia seeds (S. hispanica L.), their proteins, peptides, and their potential impact on human health. The UniProt database was used to identify the chia proteins and their amino acid sequences. The BIOPEP database was used to analyze the peptides's bioactive potential. A total of 20 proteins were cataloged in chia seed, 12 of those were involved in the regular metabolic processes of the plant cells. However, eight proteins were specifically related to production and storage of plant lipids, thus explaining the high concentration of lipids in chia seeds (around 30%), especially omega-3 fatty acids (around 20%). The analyses of amino acid sequences showed peptides with bioactive potential, including dipeptidyl peptidase-IV inhibitors, angiotensin-converting enzyme inhibitors, and antioxidant capacity. These results correlated with the main health benefits of whole chia seed in humans such as antioxidant capacity, and hypotensive, hypoglycemic, and anticholesterolemic effects. Such relation can be associated with chia protein and peptide compositions and therefore needs further investigation in vitro and in vivo.

On the use of a dielectric matching layer for ultra wideband medical applications (2012)

Ultra wideband (UWB) radio signals have gained significant attention for emerging medical applications. Communication with medical implanted sensors and actuators, biomedical radar, microwave imaging, and microwave hyperthermia are some examples of said applications. All these diagnostic and therapeutic methods necessitate the propagation of electromagnetic (EM) waves toward or from the human body. In such scenarios, a segment of the wave propagation path is inside the human body and the other segment is outside, i.e., in the free-space. This geometry creates an impedance mismatch between the two propagation environments, which results in inefficient power transmission of the EM wave. In order to improve the EM wave coupling to/from the body, a matching layer of dielectric material with the appropriate permittivity value can be used. This paper analyzes the effect of a single layer of dielectric material on the propagation of a UWB wave through the human chest in the 100--1000 MHz frequency range. Path loss models for different matching layer materials were obtained and a guideline for selecting the appropriate permittivity value is presented.

Alkyl Passivation and Amphiphilic Polymer Coating of Silicon Nanocrystals for Diagnostic Imaging (2010)

A method to produce biocompatible polymer-coated silicon nanocrystals for medical imaging is shown. Silica-embedded Si nanocrystals are formed by HSQ thermolysis. The nanocrystals are then liberated from the oxide and terminated with Si-H bonds by HF etching, followed by alkyl monolayer passivation by thermal hydrosilylation. The Si nanocrystals have an average diameter of 2.1 nm ± 0.6 nm and photoluminesce with a peak emission wavelength of 650 nm, which lies within the transmission window of 650-900 nm that is useful for biological imaging. The hydrophobic Si nanocrystals are then coated with an amphiphilic polymer for dispersion in aqueous media with the pH ranging between 7 and 10 and an ionic strength between 30 mM and 2 M, while maintaining a bright and stable photoluminescence and a hydrodynamic radius of only 20 nm. Fluorescence imaging of polymer-coated Si nanocrystals in biological tissue is demonstrated, showing the potential for in vivo imaging.
Symmetry Breaking with a Slant: Topological Defects after an Inhomogeneous Quench (1999)

We show that in second-order phase transformations that are induced by an inhomogeneous quench the density of topological defects is drastically suppressed as the velocity with which the quench propagates falls below a threshold velocity. This threshold is approximately given by the ratio of the healing length to relaxation time at freeze-out, which is the instant when the critical slowing down results in a transition from the adiabatic to the impulse behavior of the order parameter.
The human mRNA encoding the Goodpasture antigen is alternatively spliced (1993)

The noncollagenous (NC1) domain of the human collagen alpha 3(IV)-chain is the primary target of autoantibodies produced in Goodpasture syndrome and, therefore, has been designated as the Goodpasture antigen. In this report, we show that Goodpasture antigen mRNA undergoes processing to at least two alternatively spliced forms in a variety of human tissues, resulting in the exclusion of sequence encoded by either one or two exons. Interestingly, no alternatively spliced forms were observed in bovine or rat tissues. The derived amino acid sequences of the two variant mRNA forms are identical and significantly shorter than that arising from the complete Goodpasture antigen mRNA. They lack the carboxyl-terminal region contributing to the formation of the Goodpasture epitope and all but one of the cysteines found in the complete form. These sequence characteristics suggest that, if translated, the variant Goodpasture antigen is likely to be defective in triple helix formation and no longer reactive with Goodpasture autoantibodies. Although each tissue expressing Goodpasture antigen displayed a specific mRNA pattern, the complete form was always the most abundant and was present at levels apparently unrelated to whether or not the organ of origin is a potential target in Goodpasture syndrome. Furthermore, the antigen sequence was identical in the kidneys of normal and Goodpasture-affected individuals, and no major differences in the expression of the complete and spliced forms were observed.
Autoxidation and Antioxidants. Basic Principles and New Developments (1974)

Abstract There is no doubt that liquid-phase hydrocarbon autoxidation is one of the most thoroughly understood reactions in organic chemistry. Our knowledge of the elementary reactions involved in this process is so complete that it should be possible to calculate, with a reasonable degree of precision, the overall rate of autoxidation of a hydrocarbon or mixture of hydrocarbons, provided, of course, that the rate of chain initiation can be estimated. It should also be possible to make a reasonable intelligent guess at the stability of a solid system, with the reservations appropriate to the change of phase. With regard to inhibition, there is probably not a great deal of room for further improvement in the inherent efficiency of H-atom donating antioxidants. This is because a decrease in the strength of the X—H bond makes the hydrogen more susceptible to abstraction by molecular oxygen. Radical scavenging transition metal complexes also suffer from the limitation that the more reactive the complex is to ROO the more reactive it will be to O 2 . There may, of course, be further improvements in the efficiency of preventative antioxidants, particularly multi-functional antioxidants with the ability to decompose hydroperoxides and peroxides by several non-radical mechanisms and also scavenge free-radicals.
Synthesis of piperidine derivatives with a quinazoline ring system as potential antihypertensive agents. (1986)

A series of piperidine derivatives with a 2-oxo-1, 2, 3, 4-tetrahydro-quinazoline or 2, 4-dioxo-1, 2, 3, 4-tetrahydroquinazoline ring at the 4-position were prepared and tested for antihypertensive activity. Among the compounds tested, 1-[2-hydroxy-2-(3, 4-methylenedioxyphenyl)ethyl]-4-(2, 4-dioxo-1, 2, 3, 4-tetrahydro-3-quinazolinyl)piperidine (20) and 1-[2-(4-chlorophenyl)-2-hydroxyethyl]-4-(2-oxo-1, 2, 3, 4-tetrahydro-3-quinazolinylmethyl)piperidine (30) produced relatively strong hypotension in the spontaneously hypertensive rat model.
Dual-edge late-transition detector for testing the metastability effect in flip-flops (2005)

A method for determination of the metastability parameters W and /spl tau/ of flip-flops is described. The presented late-transition detector (LTD) allows for the estimation of metastability effects appearing at both types of propagation times in flip-flops (t/sub pl.H/ and t/sub pHL/) and calculation of two relevant measures of the mean time between failures (MTBF), which can be combined into a single value. The method is illustrated with the tests of four types of programmable logic devices. We used the PC-controlled test setup with dedicated test fixtures, HP-IB interface, and HP VEE software.
Porous Gold Nanospheres by Controlled Transmetalation Reaction: A Novel Material for Application in Cell Imaging (2005)

Hollow shell nanostructures have numerous potential applications due to their interesting optical and electronic properties, which can be tuned by varying their shape, size, and shell thickness. In this paper we describe a simple galvanic replacement reaction (transmetalation reaction) involving sacrificial silver nanoparticles and Au(III) ions using a dialysis membrane. The dialysis membrane acts as a partial barrier that provides excellent control over the kinetics of reaction. This process results in the formation of porous gold nanospheres that improve the fluorescence in cell staining by offering an enhanced surface area for binding of the fluorescent dye, propidium iodide (PI). Such porous nanostructures could be ideal candidates for applications such as catalysis, enzyme immobilization, and drug delivery.
FETAL PLASMA STEROIDS IN RELATION TO PARTURITION (1974)

Summary Total plasma corticosteroid levels were measured by a competitive protein‐binding technique in matched umbilical arterial and venous samples obtained from 234 infants immediately following vaginal delivery. Both arterial and venous levels were related to the gestational age of the infant at delivery, rising to a peak at 37 to 38 weeks gestational age and thereafter declining. Corticosteroid levels were generally less in infants delivered following oxytocin‐induced (or augmented) labour than in those delivered following spontaneous labour. The mean umbilical arterial levels (±S.E.) of plasma corticosteroids at 38 to 40 weeks were 213.2 ± 16.3 ng./ml. for the spontaneous labour group and 171.9 ± 12.3 ng./ml. for the oxytocin‐induced and augmented group. The corresponding mean venous levels were 242.9 ± 14.8 ng./ml. and 227.4 ± 13.2 ng./ml. The mean plasma corticosteroid level in four fetuses spontaneously miscarried at 17 to 20 weeks was 65.0 ± 21.6 ng./ml. The results suggest that the human fetal adrenal may have an active role in fetal maturation and the initiation of labour.

Finding the direction of a sound source using a vector sound-intensity probe (1993)

Good spatial resolution of a sound source can be achieved with the four closely spaced pressure transducers in a vector sound-intensity probe. In contrast, a receiving array generally requires an extensive distribution of transducer elements. Experimental results are presented that demonstrate the ability of a vector probe to determine the direction of a sound source in water, both without and with noise interference. Measurements of the sound-intensity vector, or sound-power flux, were performed using the cross-spectral method. Spectral subtraction and averaging over the frequency range of a source were found to be effective tools for determining the direction of a source when there is uncorrelated interference and background noise.

The level of persistent, bioaccumulative, and toxic (PBT) organic micropollutants contamination of Lagos soils (2013)

Lagos is a highly urbanized coastal city, with several water channels linking the Lagos lagoon, a major source of seafoods to the people of Lagos and its environs. Contamination of Lagos soil with persistent bioaccumulative and toxic organic micropullutants (PBTs) would not only affect the non-target species residing in the soil, but also a concern that the chemicals could find their way into the lagoon via soil run-off and leaching. Soil samples were collected from three busy areas of Lagos and analyzed for polychlorinated biphenyls (PCBs), organochlorine pesticides (OCS), and polycyclic aromatic hydrocarbons (PAHs). Gas chromatography with mass selective detector (GC/MSD) was used for the analyses. Iddo had the highest percent (%) organic carbon content of 39.39% with highest total PAHs of 2,706.93 ng/g. The highest total PCBs of 23.63 ng/g was found in Apapa. PCB 74 was the only PCB found in all the soils and ranged between 3.55 and 23.64 ng/g at two locations in Apapa. PBTs found in highest concentrations were naphthalene (1,625.10 ng/g) at Iddo, p,p’DDE (117.98 ng/g) at Okobaba, and PCB 74 (23.63 ng/g) at Apapa 1. The levels of PBTs in Lagos soils are hereby presented.

Myeloid leukaemogenicity and transmission of the HPRS-103 strain of avian leukosis virus. (1992)

The HPRS-103 strain of avian leukosis virus (ALV) was isolated recently from meat-type chickens and represents a new envelope subgroup. Its oncogenicity has been studied in three meat-type and five Leghorn strains of chickens. In the meat-type strains, the virus, following embryonal inoculation, induced an overall incidence of 27% myelocytic myeloid leukosis (myelocytomatosis) and 12% renal adenomas, with long median latent periods. Amongst the Leghorn lines, these tumors occurred with similar incidence in line 0, but with lower or zero incidences in the other lines. A variety of other tumours occurred with low incidence. Embryonal infection resulted in a permanently tolerant viraemic state with shedding of ALV group specific (gs)-antigen to egg albumen; contact infection resulted mainly in the development of non-shedder birds with serum virus-neutralising antibodies. Contact infection in a meat-type line was associated with the development of transient or permanent viraemia in some birds, and a low tumour incidence. A viraemic phase was not detected following contact infection in a Leghorn line and no tumours developed. The long latent period between embryo infection and tumour mortality, apparently differing from the consequences of infection with acutely transforming ALVs, and the inability of HPRS-103 ALV to transform cultured bone marrow cells, suggests that this virus may lack a viral oncogene and exert its oncogenic properties by some other mechanism such as promoter insertion activation of a cellular oncogene.

Shape-controlled assembly of luminescent dumbbell-like CdTe–cystine nanocomposites (2007)

A shape perfect luminescent dumbbell with size up to several microns was prepared by incorporating CdTe quantum dots (QDs) into locally created L-cystine matrices, and the photoluminescence of the shaped dumbbells can be easily tailored by reaction time. The growth mechanism was thoroughly investigated. This work not only gives a potential application in optical devices, but also gives a deep insight on the assembly mechanism of nanomaterials into micron-size objects.
Femtosecond erbium-doped optical fiber amplifier (1990)

A gain of 9 dB has been obtained in an erbium-doped optical fiber amplifier for input pulses with a peak power of 30 W, an average power of 30 μW (−15.2 dBm), and a pulse width of 260 fs. When the input peak power is increased in the soliton power regime, an adiabatic soliton narrowing occurs due to the optical gain. By increasing the pump power further, an optical gain enhanced soliton self-frequency shift dominates, which is due to the excitation of high-order soliton. Thus, soliton narrowing from 250 to 60 fs is observed.
Wide bandgap semiconductor transistors for microwave power amplifiers (2000)

Explores the RF power performance of microwave amplifiers fabricated from wide bandgap semiconductor transistors and demonstrates that microwave power amplifiers fabricated from 4H-SiC and AlGaN/GaN transistors offer superior RF power performance, particularly at elevated temperatures. Theoretical models predict room temperature RF output power on the order of 4-6 W/mm and 10-12 W/mm, with power-added efficiency (PAE) approaching the ideal values for class A and B operation, available from 4H-SiC MESFETs and AlGaN/GaN HFETs, respectively. All calculations were thoroughly calibrated against dc and RF experimental data. The simulations indicate operation at elevated temperature at least up to 5000/spl deg/C is possible. The RF output power capability of these devices compares very favorably with the 1 W/mm available from GaAs MESFETs. The wide bandgap semiconductor devices will find application in power amplifiers for base station transmitters for wireless telephone systems, HDTV transmitters, power modules for phased-array radars, and other applications. The devices are particularly attractive for applications that require operation at elevated temperature.
Discrete Determinants in Transfer RNA for Editing and Aminoacylation (1997)

During translation errors of aminoacylation are corrected in editing reactions which ensure that an amino acid is stably attached to its corresponding transfer RNA (tRNA). Previous studies have not shown whether the tRNA nucleotides needed for effecting translational editing are the same as or distinct from those required for aminoacylation, but several considerations have suggested that they are the same. Here, designed tRNAs that are highly active for aminoacylation but are not active in translational editing are presented. The editing reaction can be controlled by manipulation of nucleotides at the corner of the L-shaped tRNA. In contrast, these manipulations do not affect aminoacylation. These results demonstrate the segregation of nucleotide determinants for the editing and aminoacylation functions of tRNA.
