Evolutionary game theory for physical and biological scientists. II. Population dynamics equations can be associated with interpretations (2014)

The use of mathematical equations to analyse population dynamics measurements is being increasingly applied to elucidate complex dynamic processes in biological systems, including cancer. Purely 'empirical' equations may provide sufficient accuracy to support predictions and therapy design. Nevertheless, interpretation of fitting equations in terms of physical and biological propositions can provide additional insights that can be used both to refine models that prove inconsistent with data and to understand the scope of applicability of models that validate. The purpose of this tutorial is to assist readers in mathematically associating interpretations with equations and to provide guidance in choosing interpretations and experimental systems to investigate based on currently available biological knowledge, techniques in mathematical and computational analysis and methods for in vitro and in vivo experiments.

Potential on energy saving in a modular base station (2012)

The paper introduces a potential in power consumption savings in a novel modular wireless base station, being the fundamental part of the concept SAfRAN (Scalable Architecture for Resource Adaptable Network). One aspect of the concept presented in this paper is the energy saving approach using plurality of radio resources from a system bandwidth and transmitting different radio resource subsets by two or more transmitters. Because solely base station resources required for transmission are activated, the base station consumes only as much power as it is necessary to serve actual traffic. We present simulation results of macro base stations based on various modular designs and investigate their potential impact on energy consumption in comparison to a monolithic base station. Beyond energy efficiency we had in mind requirements to provide coverage on the fly, performance on the fly and bandwidth on the fly. For this we combined clustering, scalability and floating coverage approach.
Cloning of bovine RANTES mRNA and its expression and regulation in ovaries in the periovulatory period (1999)

RANTES may be one of the chemoattractants involved in stimulating eosinophils and macrophages to migrate selectively into bovine dominant follicles and into developing corpora lutea. We sequenced a 736 bp fragment of the bovine RANTES mRNA encoding the complete protein and defined the ovarian source of RANTES mRNA. As demonstrated by competitive RT-PCR, follicle-derived macrophages showed a 100-1000 times higher RANTES mRNA level compared to unpurified granulosa cells or follicle-derived fibroblasts. By means of in situ hybridization, RANTES mRNA positive macrophages were located in the former thecal layer of the developing corpora lutea.
Murine Endothelial Cell Lines as Models of Tumor Endothelial Cells (2004)

Identification of appropriate models for in vivo and in vitro preclinical testing of inhibitors of tumor angiogenesis and progression is vital to the successful development of anticancer therapeutics. Although the focus is on human molecular targets, most preclinical in vivo efficacy testing occurs in mice. The goal of the current studies was to identify a murine endothelial cell line to model tumor endothelium for studying the antiangiogenic activity of therapeutic compounds in vitro. In situ hybridization was performed on three s.c. grown syngeneic murine tumors (B16 melanoma, Lewis lung carcinoma, and CT26 colon carcinoma) to assess expression of murine homologs of human tumor endothelial cell markers in the vasculature of these tumor models. Seven murine endothelial cell lines were characterized for expression of the murine homologs of recognized endothelial cell surface markers as well as for tumor endothelial cell surface markers. The seven murine endothelial cell lines had similar generation times and five of the seven lines were able to form tubes on Matrigel. Real-time-PCR and flow cytometry analysis were used to evaluate relative mRNA and protein expression of murine homologs of several recognized endothelial cell surface markers in the seven cell lines. The expression of the mRNA for the murine homologs of five tumor endothelial cell surface markers was also evaluated. The 2H11 cell line expressed all five of the tumor endothelial cell surface markers as well as several well-recognized endothelial cells markers. The 2H11 cell line responds to known and novel antiangiogenic agents by inhibition of proliferation and tube formation. These cells can be used in in vitro angiogenesis assays for evaluating the potential antiangiogenic properties and interspecies cross-reactivity of novel compounds.
MEMS-Based Diagnostics for Turbulent Shear Flows. (1997)

Abstract : The objective of this section of the research is to develop hardware for fast processing of charge coupled display (CCD) images. This hardware will take digital CCD output and process it at the same output data rate of the CCD. The result is processed images at the maximum rate possible with a CCD camera. In particular, the hardware will perform convolutions of the input images with a digitally stored convolution kernal matrix, such as are needed for image spatial filtering and neural networks. A hardware test chip has been completed, characterized, and has been used to process images. This chip does not contain the digital front end necessary to connect directly to a CCD data stream but does demonstrate all of the critical analog components of the image processor. The test chip will be integrated with a shift register in a later chip fabrication to produce a fully functional image processor chip capable of connection to the data stream directly output from a CCD or similar row-wise serial output imaging device.

PHYSICAL PROPERTIES AND STRUCTURAL CHARACTERISTICS OF POLYMERS RESULTING FROM $sub 4$POST-EFFECT$sub 4$ POLYMERIZATION. Final Report, March 1, 1962-October 31, 1963 (1963)

Post-effect polymerization is being used to examine the mechanisms and kinetics of vinyl polymerization. The extent of polymerization and viscosity and the average molecular weight as functions of initiating dose and posteffect time at room temperature were observed. Methyl methacrylate was the monomer used in all experiments. Radiation doses up to 8.73 x 10/sup 5/ rads and post-effect times up to 194 hours were employed. A low-temperature method for quenching and transfer of viscous sample s were developed. (auth)
Neuromorphic active vision used in simple navigation behavior for a robot (2003)

We explore a neuromorphic robot vision controller which actively extracts sparse information to control the basic navigation behavior of a robot. We investigate the interaction of active vision and the robot's behavior with the objective of avoiding obstacles. A neural map recurrently connected to an active attention pointer uses edge-enhanced visual data as input. The output of the neural network is a population vector representation which contains information about the location of potential obstacles and is used to generate motor control signals. The neural network architecture which we simulated numerically is suitable for an implementation in analog VLSI technology.
REMOVAL OF NATURAL HUMAN XENOANTIBODIES TO PIG VASCULAR ENDOTHELIUM BY PERFUSION OF BLOOD THROUGH PIG KIDNEYS AND LIVERS (1993)

We have examined the nature of the binding of human xenoantibodies to pig liver and kidney vascular endothelium. Our results demonstrate that human serum contains IgM and IgG xenoantibodies that bind to pig vascular endothelium, and that the pattern of antibody binding is similar for both livers and kidneys. Immunohistochemical analysis of pig kidneys after perfusion with human blood demonstrated the binding of both IgM and IgG xenoantibodies, complement (C3), and fibrinogen to the vascular and glomerular endothelium. An ELISA assay of the perfusate after perfusion of 500 ml of human blood through a single pig kidney for 60 min demonstrated a significant reduction in the amount of human IgM (67%) and IgG (55%) binding to pig aortic endothelium. Similar perfusion experiments conducted with pig livers were associated with minimal immunohistochemical evidence of the binding of human xenoantibodies to liver vascular endothelium. Immunofluorescence staining for IgM, IgA, C3, and C1q was negative or minimally positive in the liver vascular endothelium. Sinusoidal endothelium were weakly positive for IgG and fibrinogen. The perfusion of the pig liver with human blood was, however, associated with a significant reduction in the subsequent binding of IgM and IgG to pig kidney vascular endothelium. Pig liver perfusion was also responsible for the removal of both IgM and IgG xenoantibodies capable of reacting with pig aortic endothelium, as measured by an ELISA assay of the perfusate. These results suggest that both pig kidney and livers are capable of absorbing the xenoantibodies that may be responsible for mediating a hyperacute rejection of pig xenografts and that the distribution of the target antigens for these antibodies is similar in the two organs.
Cortical Correlates of Acquired Deafness to Dissonance (2003)

Patient I.R., who had bilateral lesions in the auditory cortex but intact hearing, did not distinguish dissonant from consonant musical excerpts in behavioral testing. We additionally found that the electrical brain responses did not differentiate musical intervals in terms of their dissonance/consonance, consistent with the idea that this phenomenon depends on the integrity of cortical functions.
A geometric approach to root finding in GT(q/sup m/) (1989)

The problem of finding roots in F of polynomials in F(x) for F=GF(q/sup m/), where q is a prime or prime power and m is a positive integer greater than 1 is considered. The problem is analyzed by making use of the finite affine geometry AG(m,q). A new method is proposed for finding roots of polynomials over finite extension fields. It is more efficient than previous algorithms when the degree of the polynomial whose roots are to be found is less than dimension m of the extension field. Implementation of the algorithm can be enhanced in cases in which optimal normal bases for the coefficient field are available.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<title>Needs, requirements, and new proposals for ultra-high-speed video cameras in Japan</title> (1995)

A questionnaire was distributed to scientists and engineers all over Japan to compile information on conventional and potential application of high-speed videography and special conditions associated with using them in practice. The distribution of the required frame rate shows that existing high-speed videocameras of 10<SUP>3</SUP> to 10<SUP>4</SUP> pps cover only 30-40% of the potential usages, while existing image-converter multiframing cameras of 10<SUP>6</SUP> to 10<SUP>7</SUP> pps cover more than 90%. It is, however, clear from the authors' experiences that dynamic recognition, which is supported by videocameras but not by multiframing cameras, is an essential and very powerful tool in scientific and engineering research. New concepts to produce high-speed videocameras of 10<SUP>5</SUP> to 10<SUP>7</SUP> pps are therefore presented.
Polymer Lamellae as Reaction Intermediates in the Formation of Copper Nanospheres as Evidenced by In Situ X‐ray Studies (2020)

Abstract The classical nucleation theory (CNT) is the most common theoretical framework used to explain particle formation. However, nucleation is a complex process with reaction pathways which are often not covered by the CNT. Herein, we study the formation mechanism of copper nanospheres using in situ X‐ray absorption and scattering measurements. We reveal that their nucleation involves coordination polymer lamellae as pre‐nucleation structures occupying a local minimum in the reaction energy landscape. Having learned this, we achieved a superior monodispersity for Cu nanospheres of different sizes. This report exemplifies the importance of developing a more realistic picture of the mechanism involved in the formation of inorganic nanoparticles to develop a rational approach to their synthesis.
Centrally mediated effect of 17β-estradiol on parasympathetic tone in male rats (1999)

The following experiments were conducted to determine if peripherally administered estrogen has an effect on central autonomic tone and whether this change in tone results in an alteration in cardiovascular reflex control. Male Sprague-Dawley rats were anesthetized with thiobutabarbitol sodium (50 mg/kg) and instrumented to record blood pressure, heart rate, and vagal parasympathetic or renal sympathetic efferent nerve activity. Additional rats were instrumented to test the sensitivity of the cardiac baroreflex using intravenous injections of phenylephrine hydrochloride (0.025, 0.05, 0.1 mg/kg) or sodium nitroprusside (0. 0025, 0.005, 0.01 mg/kg) and plotting the cardiovascular responses. Intravenous injection of estrogen (10(-4), 10(-2), and 10(-1) mg/kg) produced a significant increase in vagal efferent activity and in baroreflex sensitivity. The bilateral microinjection of an estrogen receptor antagonist, ICI-182,780 (1 pM, 50 nl/side) into the nucleus ambiguus blocked both the estrogen-induced increase in vagal efferent activity and baroreflex sensitivity. These results demonstrate that in male rats estrogen acts centrally to enhance baroreflex sensitivity by increasing parasympathetic efferent tone.

Adaptive Source Localization by Mobile Agents (2006)

The problem of source localization has assumed increased importance in recent years. Applications include locating the source of a cellular phone signal, sensor localization or satellite localization. In this paper we formulate a continuous time adaptive localization algorithm that permits a mobile agent to estimate the location of a stationary source using only the measured distance from the source. The algorithm is shown to be exponentially asymptotically stable, under a persistent excitation condition that has an intuitively appealing interpretation. Exponential asymptotic stability indicates the ability of the algorithm to track modest movements of the source.
TIONets: triangular interconnection of optical networks (2002)

We propose a multihop network called TIONet or triangular interconnection of optical networks. The graph is examined from routing and scaling approaches. A store and forward routing scheme is assumed.
Dual functions of a small regulatory subunit in the mitochondrial calcium uniporter complex (2016)

Mitochondrial Ca(2+) uptake, a process crucial for bioenergetics and Ca(2+) signaling, is catalyzed by the mitochondrial calcium uniporter. The uniporter is a multi-subunit Ca(2+)-activated Ca(2+) channel, with the Ca(2+) pore formed by the MCU protein and Ca(2+)-dependent activation mediated by MICU subunits. Recently, a mitochondrial inner membrane protein EMRE was identified as a uniporter subunit absolutely required for Ca(2+) permeation. However, the molecular mechanism and regulatory purpose of EMRE remain largely unexplored. Here, we determine the transmembrane orientation of EMRE, and show that its known MCU-activating function is mediated by the interaction of transmembrane helices from both proteins. We also reveal a second function of EMRE: to maintain tight MICU regulation of the MCU pore, a role that requires EMRE to bind MICU1 using its conserved C-terminal polyaspartate tail. This dual functionality of EMRE ensures that all transport-competent uniporters are tightly regulated, responding appropriately to a dynamic intracellular Ca(2+) landscape.
Proteomic study of human bronchial epithelial cells exposed to SiC nanoparticles (2011)

The presented work proposes an optimized methodology for the study of cell exposure to nanomaterials at protein level. The study was investigated on proteins extracted from human bronchial epithelial cells exposed and non-exposed to silicon carbide nanoparticles (SiC). The analytical strategy was based on high resolution measurement using Fourier transform mass spectrometer 9.4 T. The methodology proposed succeeds in identifying over 300 proteins; most of the identified proteins are present in both exposed and non exposed cells to SiC nanoparticles. More interestingly, cytokines as Macrophage migration inhibitory factor protein could be identified only in the cells exposed to SiC nanoparticles indicating cell inflammatory response.

Propriedades do Algoritmo LMS Operando em Precisão Finita (2005)

This paper presents a new model for the behavior of the LMS algorithm when implemented in finite precision. The adaptive filter coefficients are modelated as a Markov chain and the matrix of transition probabilities are determined for the one-dimensional case. The linearization used in other models available in the literature are eliminated. Using these results, conditions on the step size for convergence to the optimum steady-state solution are determined. Algorithm behaviors not seen in the infinite precision case can be clearly identified with the proposed model. Monte Carlo simulation results ilustrate the quality of the proposed model.
Method of Probe Measurement in N<sub>2</sub>/SiH<sub>4</sub> Microwave Plasma (1994)

It has been clarified that probe current decreases linearly with increasing deposition time of a SiN film on a probe. From this result, a probe current-voltage characteristic without any deposition of the SiN film can be extrapolated from some probe current-voltage characteristics of different deposition times of the SiN film. It has been clarified that the 450 Å SiN film deposited on the probe can be removed by ion bombardment with -200 V applied to the probe for 220 s in the pure N 2 plasma ( T e \fallingdotseq13,000 K, n e \fallingdotseq5.0×10 9 cm -3 ). By repeating these two methods, it is clear that repeated ordinary probe measurement is possible in the N 2 /SiH 4 plasma. By using this method, the spatial distributions of electron temperature and electron density are measured in the N 2 /SiH 4 plasma in the deposition chamber of a double-tubed coaxial-line type microwave plasma chemical vapor deposition (MPCVD) system.
Viscosity of Liquid Fe-Cu-Si Alloy Formed in New Melting Process for Domestic Waste Incineration Residue (2001)

A new melting system is being developed to solve the problems in the treatment of ash from municipal waste incinerators. The viscosity of liquid Fe–Cu–Si ternary melt has been measured in the present work by the oscillation crucible technique in the temperature range from 1523 to 1673 K in order to obtain the basic information on the fluidity of the typical alloy system generated in the ash melting furnace. The relation between the viscosity of Fe–Cu–Si ternary alloys and 1⁄T can be expressed by Arrhenius-type formula in the temperature range from 1523 to 1673 K . Viscosity of the alloy is in the range of 5 to 7 mPa·s in the composition range of 0∼5 mass%Cu and 10∼20 mass%Si at 1723 K . These values are approximately double of that in pure Cu melt at 1723 K . From the result obtained, the appropriate condition is discussed for the operation of the melting furnace for ash from municipal solid waste incinerator.
High-pressure magnetostrictive pump development: a comparison of prototype and modeled performance (2004)

Current efforts to extend the mission profile of Unmanned Aerial Vehicles (UAVs) have highlighted the need for scalable linear actuators. Typically, electrical power and control are specified for their high specific performance and ease of maintenance and replacement. Electro-Hydraulic Actuators (EHAs) provide the advantages of electrical power and control along with the proven reliability, robustness and graceful failure modes of hydraulic actuation. Current EHA technology, however, is not scalable to the degree required for projected UAVs and extension to other markets and applications. This paper will describe the measured and theoretical performance of a magnetostrictive hydraulic pump developed for one such EHA as part of the DARPA Compact Hybrid Actuator Program (CHAP). This work will focus on prototype pump designs utilizing a resonant magnetostrictive piston driver. The numerous design and operational parameters that have been tested and studied in an effort to produce an optimized pump design will be discussed. In particular, the measured and predicted performance of the resonant structure and fluidics will be compared and contrasted for several pump designs. The paper will also examine the interdependence of pump parameters and the balance required to produce a viable design with the required performance characteristics.
