Relojería cortesana del siglo XVI. Vuelve a España el reloj de Hans de Evalo (2008)

In order to confirm the presence and determine the frequency of human immunodeficiency virus, type 1 (HIV-1) infection prior to antibody production, 23 healthy women with histories of repeated unprotected sexual exposure to HIV-1 infected hemophiliacs were tested for evidence of HIV-1 infection. Female subjects were tested for HIV-1 antibody (enzyme immunoassay [EIA] and Western blot), HIV-1 serum antigen, HIV-1 DNA gag sequences by the polymerase chain reaction, and HIV-1 virus isolation from peripheral mononuclear cells. Twenty-two of 23 (96%) women were negative by all HIV-1 assays. One woman was positive by all the HIV-1 assays including an EIA screening test for HIV-1 antibody. These preliminary results suggest that the frequency of HIV-1 infection in antibody-negative sexual partners of HIV-1 infected individuals is probably very low.
CEREAL BASED FUNCTIONAL BEVERAGES: A REVIEW (2018)

Whole grains may be processed efficiently and innovatively to create products that would be considered as healthy. A multigrain functional beverage using whole grains like barley, oats, buckwheat and red rice can be prepared. Multigrains that contain whole grains are rich in vitamins B. complex carbohydrates (starch and fiber), and minerals. The complex carbohydrates, specifically soluble fiber, help in the slow and sustained release of energy whereas the B-vitamins and minerals facilitate metabolism. Whole grains are also plentiful in phenolic compounds which have antioxidant capacities. This review deals with the application of different cereals used in the preparation of beverages.
Comparative effects of three carcinogens on human, rat and mouse hepatocytes (1989)

Ultrastructural changes commonly observed in liver cells of rodents exposed to carcinogens in vivo can be induced in hepatocytes exposed to carcinogens in vitro. Human, rat and mouse hepatocytes in primary culture were treated with actinomycin D, aflatoxin B1 (AFB1) and dimethylnitrosamine (DMN). These cultured hepatocytes were examined for ultrastructural alterations following carcinogen exposure for 24 h. Similar to the effects on liver cells in vivo, the most prominent change was a segregation of the nucleolar components. Human, rat and mouse hepatocytes, dosed with 7.9 X 10(-8) M actinomycin D, developed nucleolar segregation in 86%, 98% and 55% of cells, respectively. When incubated with 3.2 X 10(-6) M AFB1, 60% of human and 84% of rat hepatocytes developed nucleolar segregation. However, exposures of mouse hepatocytes less than or equal to 3.2 X 10(-5) M of AFB1 failed to induce segregation of the nucleolus. DMN administered at a dose of 2.0 X 10(-2) M caused segregation in 11% of the rat hepatocytes and in 60% of the mouse hepatocytes. Distinct nucleolar segregation did not occur in human hepatocytes until they were exposed to a concentration of 5.0 X 10(-2) M DMN (31%). Actinomycin D, AFB1, DMN, as well as other compounds that bind to DNA and interfere with template activity cause nucleolar segregation. Morphologic changes observed in cultured rat and mouse hepatocytes correlate well with in vivo experiments with regard to the relative sensitivity of rats and mice to toxicological effects of these carcinogens. Thus, hepatocyte cultures may provide a realistic system to determine the sensitivity of human liver cells to carcinogens.
Secure Broadcast with One-Time Signatures in Controller Area Networks (2013)

Broadcast authentication in Controller Area Networks (CAN) is subject to real time constraints that are hard to satisfy by expensive public key primitives. For this purpose the authors study here the use of one-time signatures which can be built on the most computationally efficient one-way functions. The authors use an enhancement of the classical Merkle signature as well as the more recently proposed HORS signature scheme. Notably, these two proposals offer different trade-offs, and they can be efficiently paired with time synchronization to reduce the overhead caused by the re-initialization of the public keys, which would otherwise require expensive authentication trees. The authors do outline clear bounds on the performance of such a solution and provide experimental results on development boards equipped with Freescale S12X, a commonly used automotive grade micro-controller. The authors also benefit from the acceleration offered by the XGATE co-processor available on S12X derivatives which significantly increases the computational performances.

The Measurement and Analysis of Chaotic Music (1959)

This paper presents the measurement and analysis of chaotic signals which is constituted by the resonant Chua's circuit. The signals are recorded by using the amplifier and speakers when the resonance occurs. We apply the Gold wave audio software to record the chaotic signals. At first, we analyze the chaotic signals generated by existing low-loss inductance and loss less inductance. The loss less inductance is implemented by an operational amplifier. We also measure the signals with single loop and double scroll. Finally, we add external signal to the existing low-loss inductance, loss less inductance for measurement and analysis.
Differential effect of the rd mutation on rods and cones in the mouse retina. (1978)

The retinas of rd/rd C57BL/6J-rd le mice have been examined by light and electron microscopy to determine whether rod cell degeneration precedes cone cell degeneration. In all regions of the eye, a rapid rod degeneration precedes a much slower cone degeneration. Only about 2% of the rods remain in the posterior region at postnatal day 17, and none by the day 36. By contrast, at least 75% of the cone nuclei remain at day 17. Although most of these slowly disappear, about 1.5% of the original population of cone nuclei in the posterior retina is still present at 18 months of age. A central to peripheral temporal gradient of degeneration exists, such that some rod nuclei persist in the far periphery up to day 47, but none is found at day 65. About 5% of the cone nuclei are still present in the far periphery at 18 months of age.
Polypropylene matrix composites reinforced with pre‐stressed glass fibers (1998)

Abstract Thermoplastic matrix composites have recently emerged as promising engineering materials because of their desirable properties such as high service temperatures, high impact resistance, and processing advantages. However, residual stresses in composites introduced during fabrication are cited as one of the most significant problems in the processing of composites. In some instances these stresses have been shown to significantly degrade the strength of the material, resulting in matrix cracking, debonding, reduced fracture toughness, and delamination. In this work, studies have been carried out on glass fiber reinforced polypropylene composites formed by compression molding process from co‐mingled fabrics. The fibers were pre‐stressed during the process to produce high performance composite products with low residual microstresses, which are harmful to the properties of the composite. Mechanical tests showed that pre‐stress can increase the tensile, flexural and interlaminar shear properties of the composites, and there exists an optimum pre‐stress level to gain best properties for each external loading condition.
DIET, OBESITY, AND RISK OF FATAL PROSTATE CANCER1 (1984)

Findings described in this report are for 6,763 white male Seventh-day Adventists who completed a dietary questionnaire in 1960. Between 1960 and 1980 mortality data were collected on cohort members. Overweight men had a significantly higher risk of fatal prostate cancer than men near their desirable weight. The predicted relative risk of fatal prostate cancer was 2.5 for overweight men. Suggestive positive associations were also seen between fatal prostate cancer and the consumption of milk, cheese, eggs, and meat. There was an orderly dose-response between each of the four animal products and risk. The predicted relative risk of fatal prostate cancer was 3.6 for those who heavily consumed all four animal products. The results of this study and others suggest that animal product consumption and obesity may be risk factors for fatal prostate cancer.
Coiling of viscous jets (2004)

A stream of viscous fluid falling from a sufficient height onto a surface forms a series of regular coils. I use a numerical model for a deformable fluid thread to predict the coiling frequency as a function of the thread's radius, the flow rate, the fall height, and the fluid viscosity. Three distinct modes of coiling can occur: viscous (e.g. toothpaste), gravitational (honey falling from a moderate height) and inertial (honey falling from a great height). When inertia is significant, three states of steady coiling with different frequencies can exist over a range of fall heights. The numerically predicted coiling frequencies agree well with experimental measurements in the inertial coiling regime.
Aqueous Recovery from Cotton Swabs of Organic Explosives Residue Followed by Solid Phase Extraction (1999)

Abstract A common procedure for processing cotton swabs containing organic explosives residue involves soaking the cotton in acetone or other organic solvent to extract the explosives, followed by direct analysis of the resulting sample solution using chromatography—mass spectrometry (LC- or GC-MS). A water-based procedure was developed to solve problems arising from co-extraction of sample matrix. Common nitro-organic explosives were extracted from cotton into water; the explosives were isolated by solid phase extraction, using a poly-N-vinylpyrrolidone-divinylbenzene sorbent; samples were screened by LC-UV; and the presence of explosives was confirmed by LC- or GC-MS and fast GC-TEA (EGIS). Explosives residue samples were generated by mixing standards in motor oil on aluminum foil, by detonating four different bombs (C-4, a dynamite, a binary explosive, and TNT) hidden inside suitcases filled with clothing, and by handling a plastic explosive (Semtex H). Ninety-six paired samples were processed by the two procedures (acetone-based and water-based). The water extraction/SPE process was just as effective in recovering organic explosives from cotton swabs, and it better rejected the sample matrix, giving much greater selectivity with all samples except clothing. Water-based samples were screened with high accuracy by LC-UV, and the LC-UV and LC-MS semi-quantitative results were highly correlated.

Citrus peel as a source of functional ingredient: A review (2016)

Citrus plants belonging to the family Rutaceae which include fruits such as orange, mandarin, lime, lemon, sour orange and grapefruitappear as a well known promising source of multiple beneficial nutrients for human beings. Processing of citrus by-products potentially represents a rich source of phenolic compounds and dietary fibre, owing to the large amount of peel produced. These citrus fruit residues, which are generally discarded as waste in the environment, can act as potential nutraceutical resources. Due to their low cost and easy availability such wastes are capable of offering significant low-cost nutritional dietary supplements. The utilization of these bioactive rich citrus residues can provide an efficient, inexpensive, and environment friendly platform for the production of novel nutraceuticals or for the improvement of older ones. This review systematically summarized the potential components present in citrus peel, which generally discarded as waste.

Delta‐sigma oscillators: versatile building blocks (1997)

Delta–sigma modulators have long been used in signal-processing applications to simplify arithmetic operations. Their ability to trade bandwidth for quantization levels has been exploited to reduce hardware requirements and speed up computations. This paper will introduce a class of circuits called delta–sigma oscillators which use this property to efficiently generate spectrally pure analogue signals. Subsequently we will show how this approach can be extended to generate various multitone signals such as AM and FM signals. Delta–sigma modulators with various noise-shaping properties are at the core of these new designs. Owing to their small-silicon-area requirements and digital implementation, delta–sigma oscillators have been identified as an important building block for built-in self-test schemes for mixed-signal circuits and systems. They are also envisioned to be useful building blocks for various control and communication system applications. © 1997 by John Wiley & Sons, Ltd.
Digital Microfluidic Sampler for a Portable Capillary Electropherograph (2009)

A new sample introduction/analysis approach was developed by combining a digital microfluidic (DMF) device with a portable capillary electrophoresis (CE) analyzer based on short separation capillary and contactless conductivity detection. The DMF sample injection was performed by transporting sample and buffer droplets in succession under the CE capillary inlet end allowing the capillary to be immersed into the sample/buffer droplet, and CE separation was performed by applying a high voltage between the (grounded) buffer droplet and CE outlet reservoir. Electrowetting on dielectric (EWOD) phenomenon was used for droplets actuation. With the use of the DMF sampler, CE separation of a mixture of vitamins was achieved. A droplet evaporation process with simultaneous concentration of sample in the droplet was monitored. It was found that the concentration process closely followed the theoretically predicted function.
Interspecies Cross-Reactivity of Monoclonal Antibodies Directed Against Human Sperm Antigens (1984)

Monoclonal antihuman sperm antibodies were used to study the surface antigens of sperm from man, monkey (Macaca mulatta), dog, rabbit, bull and mouse. Quantitative absorption results indicate some of the antibodies cross-react with sperm of all the species tested while three recognized determinants were unique to the human sperm. These reactions were sperm-specific since no cross-reactivity was observed with somatic tissue from human and mouse. In the indirect immunofluorescence test, monoclonal antibodies MA1 and MA4 recognize antigenic determinants which appear within the mouse testis during spermatogenesis and are present on the acrosome and mid-piece sperm regions, respectively, of the species tested. MA2 reacted diffusely with the acrosome of human and monkey sperm only. In contrast, MA3 had a speckled acrosomal staining pattern reacting only with human sperm. Antibodies MA5 and MA6 were also specific for human sperm, binding to the equatorial and tail regions. Live human and monkey sperm were agglutinated and immobilized by MA1 but only immobilized by MA2 . With the Western blot technique, human sperm antigens of approximately 84,000, 240,000, 30,000 and 71,000 daltons were identified by antibodies MA1 , MA3 , MA4 and MA5 , respectively. An acrosomal antigen of approximately 82,000 daltons present on both bull and mouse sperm was identified by MA1 . Antibody MA4 , in turn, identified at 28,000-dalton mouse sperm antigen and a 35,000- to 37,000-dalton antigen present on the midpiece of bull sperm.
On the Resolution Function for Digitally Stabilized Nuclear Spectrometers (1970)

A comprehensive control theory of digitally stabilized nuclear spectrometers has provided a quantitative basis for the optimal selection of various system parameters. The theoretical predictions are compared with measured resolution functions for a stabilized Ge(Li) photon spectrometer. Implications for stabilizer design will be discussed.
Low-cost broadband circularly polarized probe-fed patch antenna for WLAN base station (2003)

Operation with CP (circular polarization) requires no strict orientation between the transmitter and the receiver for wireless communications, and is very suitable for applications in wireless local area network (WLAN) to overcome multipath fading problems and enhance system performance. However, for practical applications in the 2.4 GHz WLAN band (2400-2484 MHz), a wide CP bandwidth (larger than about 3.5%) is required. For this purpose, we demonstrate a novel and simple broadband circularly polarized patch antenna comprising a corner-truncated square patch, an L-shaped ground plane, and a single probe feed. The proposed antenna can be easily constructed at low cost, and have an impedance bandwidth (1:1.5 VSWR) of about 30%, a CP bandwidth (3 dB axial ratio) of about 10.4% and a gain level of 8.5 dBi or larger within the CP bandwidth. The obtained CP performance is among the best that have been reported for single-feed single-element patch antennas.
Improved generalization through learning a similarity metric and kernel size (2005)

Nearest-neighbour interpolation algorithms have many useful properties for applications to learning, but they often exhibit poor generalization. In this paper, it is shown that much better generalization can be obtained by using a variable interpolation kernel in combination with conjugate gradient optimization of the similarity metric and kernel size. The resulting method is called variable-kernel similarity metric (VSM) learning. It has been tested on a number of standard classification data sets, and on these problems it shows better generalization than backpropagation and most other learning methods. An important advantage is that the system can operate as a black box in which no model minimization parameters need to be experimentally set by the user. The number of parameters that must be determined through optimization are orders of magnitude less than for backpropagation or RBF networks, which may indicate that the method better captures the essential degrees of variation in learning.
“What's American About America?”: A Structuralist Approach (1980)

The quotation marks in my title offer homage to John A. Kouwenhoven for a stimulating essay he published under that name more than twenty years ago. In it he brought under one intuitive umbrella such diverse Americana as the Manhattan skyline, the gridiron town plan, the skyscraper, jazz, the Constitution, Mark Twain's writing, Walt Whitman's Leaves of Grass , assembly-line production, and chewing gum. What united them all, he felt, was their embodiment of process—the ongoing changingness that was the essence of America. Brilliant as the essay may be, it remains inspired journalism because Kouwenhoven had no method to propose except his own cultivated intuition. In this essay I shall speak of several of the same American phenomena but in a context intended to meet the need for a theory and a method to guide the complex business of making sense of American distinctiveness.
Free-space optical interconnects using connectivity-enhanced, mesh-based networks (1994)

We discuss the potential of using free-space optical methods to implement a class of connectivity-enhanced mesh-based networks. As shown, the unique advantages that the free-space optics can offer, including large power fan-out per node capability, and the ability for spatial-angular multiplexing make it possible for connectivity-enhanced mesh-based networks to be efficiently implemented. In our presentation, two switching models, one for nonblocking point-to-point switching and the other for nonblocking broadcast switching, are described for their optical implementations. Some proof-of-principle experimental results are presented.
Endoscopic hematoma evacuation in patients with spontaneous supratentorial intracerebral hemorrhage (2014)

With the introduction of the minimally invasive techniques and the evolution of the neuroendoscope and hemostatic agents, the median operative time and blood loss have been significantly decreased. Although the hematoma evacuation rates were similar between the endoscope (90%) and craniotomy (85%) groups, the median intensive care unit stay was decreased from 11 days to 6 days due to reduced surgical invasiveness. This represents an important advancement in treating spontaneous supratentorial ICH, and provides a measured preview of the promising results that can be expected in the future.

A new method of decoupling for gradient systems in MRI (2013)

A set of external coils is designed to eliminate the induced voltage in shim coils caused by the changing current in the gradient coils. By placing the external coil near the line which supplies the current for the gradient coil in a certain way and inserting it into the circuit of shim coils, a induced voltage which has the same wave form with the induced voltage in the shim coil is generated and consequently the coupling between the shim coil and the gradient coil is eliminated. Moreover, the induced voltages of various shim coils are simulated and the parameter of one external coil is determined by the result of the simulation.
Pathologic changes of mammillary body in clinical and experimental brain hemorrhage. (1993)

The histomorphologic changes of the mammillary bodies (MB) in 31 patients and 8 spontaneously hypertensive rats with brain hemorrhage were studied by light and electron microscopy. The results showed that the frequency of the ischemic change neurons in medial nucleus in MB is much higher than that in hippocampal CA1 section and multiplicated double-deck or multistratum basal lamina formed a network or branch pattern, which indicate that MB may be of important function.
