EGF and TGF‐α in wound healing and repair (1991)

Wound healing is a localized process which involves inflammation, wound cell migration and mitosis, neovascularization, and regeneration of the extracellular matrix. Recent data suggest the actions of wound cells may be regulated by local production of peptide growth factors which influence wound cells through autocrine and paracrine mechanisms. Two peptide growth factors which may play important roles in normal wound healing in tissues such as skin, cornea, and gastrointestinal tract are the structurally related peptides epidermal growth factor (EGF) and transforming growth factor alpha (TGF-alpha). EGF/TGF-alpha receptors are expressed by many types of cells including skin keratinocytes, fibroblasts, vascular endothelial cells, and epithelial cells of the GI tract. In addition, EGF or TGF-alpha are synthesized by several cells involved in wound healing including platelets, keratinocytes, and activated macrophages. Healing of a variety of wounds in animals and patients was enhanced by treatment with EGF or TGF-alpha. Epidermal regeneration of partial thickness burns on pigs or dermatome wounds on patients was accelerated with topical application of EGF or TGF-alpha, and EGF treatment accelerated healing of gastroduodenal ulcers. EGF also increased tensile strength of skin incisions in rats and corneal incisions in rabbits, cats, and primates. Additional research is needed to better define the roles of EGF, TGF-alpha and their receptor in normal wound healing, to determine if alterations have occurred in the EGF/TGF-alpha system in chronic wounds, and optimize vehicles for effective delivery of peptide growth factors to wounds.
Integrated Millimeter-Wave Silicon Micromachined Filters (2000)

This paper describes the design and the fabrication of a new type of millimeter-wave micromachined band pass filters, using silicon waveguides. The main interest of these components is their ability to be integrated along with other MMICs using flip chip bonding techniques. The micromachining fabrication technique allows to maintain very good fabrication tolerances, while the resulting filters are very compact. The design methodology is presented along with two examples of two and four pole filters at 42 GHz.
Comparison of Chimpanzee and Human Leukocyte Ig-Like Receptor Genes Reveals Framework and Rapidly Evolving Genes (2001)

The leukocyte receptor complex (LRC) on human chromosome 19 contains related Ig superfamily killer cell Ig-like receptor (KIR) and leukocyte Ig-like receptor (LIR) genes. Previously, we discovered much difference in the KIR genes between humans and chimpanzees, primate species estimated to have approximately 98.8% genomic sequence similarity. Here, the common chimpanzee LIR genes are identified, characterized, and compared with their human counterparts. From screening a chimpanzee splenocyte cDNA library, clones corresponding to nine different chimpanzee LIRs were isolated and sequenced. Analysis of genomic DNA from 48 unrelated chimpanzees showed 42 to have all nine LIR genes, and six animals to lack just one of the genes. In structural diversity and functional type, the chimpanzee LIRs cover the range of human LIRs. Although both species have the same number of inhibitory LIRs, humans have more activating receptors, a trend also seen for KIRs. Four chimpanzee LIRs are clearly orthologs of human LIRs. Five other chimpanzee LIRs have paralogous relationships with clusters of human LIRs and have undergone much recombination. Like the human genes, chimpanzee LIR genes appear to be organized into two duplicated blocks, each block containing two orthologous genes. This organization provides a conserved framework within which there are clusters of faster evolving genes. Human and chimpanzee KIR genes have an analogous arrangement. Whereas both KIR and LIR genes can exhibit greater interspecies differences than the genome average, within each species the LIR gene family is more conserved than the KIR gene family.
Prevention of Renal Fibrin Deposition in Endotoxin-induced DIC through Inhibition of PAI-1 (2000)

Plasminogen activator inhibitor-1 (PAI-1) increases in endotoxemia thus possibly cooperating in altering the hemostatic balance in a prothrombotic direction. The effect of the inhibition of PAI-1 with the monoclonal antibody MA-33B8 was studied systemically and in kidneys in a lapine model of endotoxin-induced disseminated intravascular coagulation (DIC). The increase in plasmatic PAI activity in the control group (n = 9) was inhibited in the MA-33B8 treated rabbits (n = 5). Control rabbits showed renal fibrin deposits, whereas only one of the MA-33B8 rabbits did so. These results were confirmed immunohistochemically in kidneys as PAI-1 immunostaining was seen inside the glomeruli and larger vessels in the control group, whereas MA-33B8 rabbits showed a remarkable decrease, demonstrating that MA-33B8 successfully inhibited PAI-1 in the kidneys as well. Therefore evidence for the important role of PAI-1 in fibrin generation in endotoxin-induced DIC is presented, suggesting that strategies aiming at its reduction can be useful in this pathology.
A Survey of Deep Learning: Platforms, Applications and Emerging Research Trends (2018)

Deep learning has exploded in the public consciousness, primarily as predictive and analytical products suffuse our world, in the form of numerous human-centered smart-world systems, including targeted advertisements, natural language assistants and interpreters, and prototype self-driving vehicle systems. Yet to most, the underlying mechanisms that enable such human-centered smart products remain obscure. In contrast, researchers across disciplines have been incorporating deep learning into their research to solve problems that could not have been approached before. In this paper, we seek to provide a thorough investigation of deep learning in its applications and mechanisms. Specifically, as a categorical collection of state of the art in deep learning research, we hope to provide a broad reference for those seeking a primer on deep learning and its various implementations, platforms, algorithms, and uses in a variety of smart-world systems. Furthermore, we hope to outline recent key advancements in the technology, and provide insight into areas, in which deep learning can improve investigation, as well as highlight new areas of research that have yet to see the application of deep learning, but could nonetheless benefit immensely. We hope this survey provides a valuable reference for new deep learning practitioners, as well as those seeking to innovate in the application of deep learning.
Flüssig‐kristalline Polymere (1988)

Abstract Makromolekular aufgebaute Werkstoffe sind wegen ihrer vielseitigen Anwendbarkeit und der leichten Formgebung aus der Technik nicht mehr wegzudenken. Die rasante Entwicklung der makromolekularen Chemie der letzten Jahre hat gezeigt, wie die gezielte Modifikation der Monomer‐Bausteine zu Materialien mit neuen Anwendungsperspektiven führt. Im ersten Beitrag der Reihe über polymere Werkstoffe [1] wurde dargestellt, wie sich die Anwendungsbreite makromolekularer Werkstoffe durch Mischen von zwei Polymeren noch wesentlich erweitern läßt. Im vorliegenden Artikel soll die Rede von sogenannten flüssig‐kristallinen Polymeren sein, d. h. von Makromolekülen, bei denen ein gewisses Maß an Ordnung auch noch in der Schmelze vorliegt.
FGL chaperone-assembled fimbrial polyadhesins: anti-immune armament of Gram-negative bacterial pathogens (2007)

This review summarizes the current knowledge on the structure, function, assembly, and biomedical applications of the family of adhesive fimbrial organelles assembled on the surface of Gram-negative pathogens via the FGL chaperone/usher pathway. Recent studies revealed the unique structural and functional properties of these organelles, distinguishing them from a related family, FGS chaperone-assembled adhesive pili. The FGL chaperone-assembled organelles consist of linear polymers of one or two types of protein subunits, each possessing one or two independent adhesive sites specific to different host cell receptors. This structural organization enables these fimbrial organelles to function as polyadhesins. Fimbrial polyadhesins may ensure polyvalent fastening of bacteria to the host cells, aggregating their receptors and triggering subversive signals that allow pathogens to evade immune defense. The FGL chaperone-assembled fimbrial polyadhesins are attractive targets for vaccine and drug design.
Numerical analysis: an introduction (1998)

This is a text in numerical analysis which is taken to mean the branch of mathematics that develops and analyzes computational methods dealing with problems arising in classical analysis, approximations theory, the theory of equations, and ordinary differential equations. The topics in this book are presented with a view towards stressing basic principles and maintaining simplicity and teachability as far as possible. Topics that require a level of technicality that goes beyond the standard of simplicity imposed are referenced in bibliographic notes at the end of each chapter. This book does not cover numerical linear algebra, nor the numerical solution of partial differential equations, as the author takes the view that these are now separate disciplines. It is intended that the student has a good background in calculus and advanced calculus and some knowledge of linear algebra, complex analysis, and differential equations.
Efficiency of magnetic plane wave pumping of a ferrofluid through a planar duct (2011)

The efficiency of ferrohydrodynamic pumping of a ferrofluid through a planar duct by means of a running magnetic plane wave is studied to second order in the amplitude of the exciting current density. The rate of dissipation in the fluid is calculated from the first order magnetic field and magnetization. It turns out that the efficiency, defined as the ratio of net flow velocity to power input, is comparable in magnitude to that for Stokes peristaltic pumping. The theory for electrohydrodynamic pumping of a polar liquid by means of a running electric plane wave is shown to be nearly identical.
A Dynamically Reconfigurable Ambipolar Black Phosphorus Memory Device (2016)

Nonvolatile charge-trap memory plays an important role in many modern electronics technologies, from portable electronic systems to large-scale data centers. Conventional charge-trap memory devices typically work with fixed channel carrier polarity and device characteristics. However, many emerging applications in reconfigurable electronics and neuromorphic computing require dynamically tunable properties in their electronic device components that can lead to enhanced circuit versatility and system functionalities. Here, we demonstrate an ambipolar black phosphorus (BP) charge-trap memory device with dynamically reconfigurable and polarity-reversible memory behavior. This BP memory device shows versatile memory properties subject to electrostatic bias. Not only the programmed/erased state current ratio can be continuously tuned by the back-gate bias, but also the polarity of the carriers in the BP channel can be reversibly switched between electron- and hole-dominated conductions, resulting in the erased and programmed states exhibiting interchangeable high and low current levels. The BP memory also shows four different memory states and, hence, 2-bit per cell data storage for both n-type and p-type channel conductions, demonstrating the multilevel cell storage capability in a layered material based memory device. The BP memory device with a high mobility and tunable programmed/erased state current ratio and highly reconfigurable device characteristics can offer adaptable memory device properties for many emerging applications in electronics technology, such as neuromorphic computing, data-adaptive energy efficient memory, and dynamically reconfigurable digital circuits.
Hydrogels from polysaccharides. II. Beads with cellulose derivatives (1996)

The generation of hydrogels from solutions of cellulose ester derivatives of various types using an atomization device, in which the solution travels through air before phase inversion occurs in a nonsolvent, was unable to produce beads in spherical shape. Instead, irregularly shaped particles were formed. The cellulose derivatives included a series of cellulose esters with a high and low degree of substitution (DS) and with acyl substituents ranging in size from C3 to C12 (laurate). Starch was tested as a noncellulosic polysaccharide, and the list of cellulose derivatives included a fluorine containing ester. The formation of spherical hydrogel beads by this method became possible only when cellulose derivatives or starch were blended in solution with unmodified cellulose. The resulting beads had dynamic flow characteristics, for instance, linear velocity vs. pressure drop relationships, that closely followed the rule of mixing. An exception was cellulose laurate, which retained most of the strength of unblended cellulose even at 60% derivative content. The results suggest (a) that cellulose is needed for the formation of droplets with sufficiently high surface tension capable of withstanding the collision with the nonsolvent surface; (b) that cellulose derivatives require the presence of unmodified cellulose to attain sufficient gel strength; and (c) that waxy ester substituents provide the basis for hydrophobic interactions which contribute to gel strength retention. © 1996 John Wiley & Sons, Inc.
New considerations for travelling wave particle handling (2002)

Different small-scale devices for particle micro-handling using an AC electric field boundary wave were proposed by F.M. Moesner et. al. (1995). These devices, with various novel transportation and manipulation features, that instantly generate particle driving forces through electric field creation, have been designed and produced. In a further endeavour, the mechanisms of particle conveyance are subsequently validated in experiments. Particles on a thin protecting and insulating film interface above a series of encased and insulated parallel field electrodes become either tribo-electrically or induction charged through the application of balanced three- or six-phase voltages. The created nonuniform travelling field-wave conveys the charged particles perpendicular to the electrodes by repulsive forces in a hopping mode from electrode to electrode. In a temperature and humidity controlled environment, experiments surveying particle conveyance dynamics on these electric devices have been carried out with help of a high speed camera. The applied experimental voltages included triangular, ramp and two customized profiles. Various particle materials with diameters up to 400 /spl mu/m have been examined; metal, glass, and plastic spheres showed the best performances. The transient charge distribution on particles and on the activated electric device, which is responsible for the particle conveyance, has been inspected by a modified scanning electron microscope (SEM). Further, theoretical considerations underline the experimental findings.
Human Medullary Thyroid Carcinoma in Culture Provides a Model Relating Growth Dynamics, Endocrine Cell Differentiation, and Tumor Progression* (1984)

We used an unique model, human medullary thyroid carcinoma (MTC) in culture (the TT line), to study features of neuroendocrine-related biochemistry in relationship to growth, differentiation, and tumor progression. Tumor tissues from patients with virulent MTC contain a very heterogeneous distribution of cells staining for calcitonin (CT) and have a high ratio of intracellular L-dopa decarboxylase activity (DDC) to CT. We found, in a culture line of MTC derived from a patient with virulent disease, that the degree of the inverse relationship between DDC and CT and the heterogeneous cellular distribution of CT probably relate to the rate of cellular growth and the biochemical set of individual cell clones. During exponential growth of the parent TT cell line, intracellular DDC and CT varied. DDC increased by 70% and CT decreased by 40%. Single time-point measurements in 54 cell clones or highly enriched cell populations revealed a more dramatic variability for CT (15-fold) than for DDC (5-fold). During growth of the clones having the highest and lowest CT measurements, respectively, inverse dynamics between DDC and CT were again found. However, each clone maintained a distinct range of CT during the entire growth curve, with a 2- to 4-fold difference in CT between the two clones throughout. In the low producing CT clone, ratios between DDC and CT rose to greater than 1.0 during growth, a very high value found before this study only in MTC tissues from patients with virulent disease. Immunohistochemical staining for CT of parent cells and clones grown on embryonic chick skin revealed increased cellular heterogeneity for CT distribution during growth. The TT line provides a powerful tool to study neuroendocrine related biochemical events in relationship to growth, differentiation, and tumor progression in MTC. Our in vitro findings in the TT line well explain observations made previously in patients. We conclude that: (1) DDC, a neural property of MTC, is an early differentiation marker as compared to CT and that the differentiation status of MTC cells varies inversely with cell growth rate; and (2) in patients with MTC, the virulence of the tumor probably varies inversely with differentiation status. The inverse ratio of DDC to CT is probably determined in MTC by the proportion of rapidly growing cells and numbers of cell clones which have a poor ability for maturation.
From Platinum Blues to Rhodium and Iridium Blues (1999)

Tetrametallic rhodium and iridium blues, related to the well-known platinum blues, are formed by redox condensation of dinuclear pyrazolato rhodium and iridium complexes in different oxidation states. The metal atoms in these novel complexes, such as the cation [{Rh(μ-pz)(CNtBu)2}4]2+, have a fractional oxidation state of 1.5.
Conformation of the synaptobrevin transmembrane domain (2006)

The synaptic vesicle protein synaptobrevin (also called VAMP, vesicle-associated membrane protein) forms part of the SNARE (soluble N-ethylmaleimide sensitive factor attachment protein receptor) complex, which is essential for vesicle fusion. Additionally, the synaptobrevin transmembrane domain can promote lipid mixing independently of complex formation. Here, the conformation of the transmembrane domain was studied by using circular dichroism and attenuated total reflection Fourier-transform infrared spectroscopy. The synaptobrevin transmembrane domain has an alpha-helical structure that breaks in the juxtamembrane region, leaving the cytoplasmic domain unstructured. In phospholipid bilayers, infrared dichroism data indicate that the transmembrane domain adopts a 36 degrees angle with respect to the membrane normal, similar to that reported for viral fusion peptides. A conserved aromatic/basic motif in the juxtamembrane region may be causing this relatively high insertion angle.

Crystal and molecular structure of thieno[2″,3″:4′,5′]thieno[2′,3′-d]thieno-[3,2-b]thiophene as a hydrogen-poor heterocycle (1992)

The crystal and molecular structure of the polythiophene 4 and its charge-transfer complex with tetracyanoquinodimethane (TCNQ) have been determined. Crystal data: 4, C10H4S4, M= 252.38, monoclinic, P21/n, a= 11.462(1), b= 4.026(1), c= 10.437(1)Å, β= 103.77(1)°, V= 467.8(1)Å3, Z= 2, D= 1.792 g cm–3; 4·(TCNQ), C22H8N4S4, M= 456.60, triclinic, P, a= 7.533(1), b= 10.807(1), c= 7.094(2)Å, α= 90.12(2), β= 92.13(2), γ= 124.55(1)°, V= 475.1(2)Å3, Z= 1, D= 1.596 g cm–3. The molecules in the crystals of 4 are arranged in a zig-zag fashion along the diagonal line through the a and c axes, with notably short intermolecular S–S distances (3.482 and 3.526 Å). The occurrence of short S–S contacts, which are not observed in the lower homologues of the linearly-condensed polythiophenes 2 and 3, are discussed in terms of the low S : H ratio on the molecular periphery. A short S–S contact (3.604 Å) was also observed in the crystal of a 1 : 1 charge–transfer complex of 4 with TCNQ, which forms a mixed stack of donor and acceptor molecules.
Performance Study of a Vortex-Stabilized Arc Radiation Source (1965)

An extensive investigation of a vortex-stabilized arc radiation source has been made in which arc current, gas pressure, gas flow rate, and nozzle diameter were the prime variables. Both the total radiance and spectral distribution were measured. Within the experimental range investigated with argon as the arc gas, the radiance is proportional to the 1.6 power of the current, the 0.4 power of the pressure, and the 0.35 power of the gas flow rate and is inversely proportional to the 2.6 power of the nozzle diameter. The total radiance and spectral distribution are primarily functions of gas composition. Argon had the highest total radiance with a substantial radiation continuum and a superimposed broad line structure. Helium exhibited primarily a sharp line structure. Oxygen, air, and nitrogen had a substantial portion of radiant energy in the infrared. The maximum source radiance obtained with a vortex-stabilized argon arc was 5250 W cm−2 sr−1.
