Nutritive perfusion at donor site after microvascular fibula transfer (2003)

There are many reports on the versatility of the fibular flap, but only a few studies have reported on the morbidity, and none on the nutritive perfusion, of the donor site. This study describes for the first time the quantitative investigation of nutritive perfusion at the donor site after osteomyo-cutaneous fibula transfer. Tissue nutrition of the lower leg was measured in 25 patients by micro-lightguide spectrophotometry and laser Doppler flowmetry. In a standardized examination, hemoglobin oxygenation and blood flow of the donor leg and the contralateral leg (intraindividual control) were measured at the nutritive region of the peroneal artery (I), posterior tibial artery (II), and anterior tibial artery (III). In the operated leg, blood flow was significantly reduced in region I with the sacrificed peroneal artery, and significantly increased in region II and III, probably for compensation (P = 0.03). Decreased hemoglobin oxygenation and blood flow of the peroneal region at the donor site were without significance in comparison to the control leg (P = 0.55 and P = 0.35, respectively). Decreased nutritive perfusion at the donor site was below the threshold of clinical manifestation, and supports the low donor site morbidity following fibular grafting.
Resonant Mie Scattering (RMieS) correction of infrared spectra from highly scattering biological samples (2009)

Infrared spectra of single biological cells often exhibit the 'dispersion artefact' observed as a sharp decrease in intensity on the high wavenumber side of absorption bands, in particular the Amide I band at approximately 1655 cm(-1), causing a downward shift of the true peak position. The presence of this effect makes any biochemical interpretation of the spectra unreliable. Recent theory has shed light on the origins of the 'dispersion artefact' which has been attributed to resonant Mie scattering (RMieS). In this paper a preliminary algorithm for correcting RMieS is presented and evaluated using simulated data. Results show that the 'dispersion artefact' appears to be removed; however, the correction is not perfect. An iterative approach was subsequently implemented whereby the reference spectrum is improved after each iteration, resulting in a more accurate correction. Consequently the corrected spectra become increasingly more representative of the pure absorbance spectra. Using this correction method reliable peak positions can be obtained.

The platform is capable of fabricating extremely complex conductive circuits, strain and pressure sensors, stretchable wires, and wearable circuits with high yield and repeatability.
Fortifying Intrusion Detection Systems in Dynamic Ad Hoc and Wireless Sensor Networks (2014)

We investigate three aspects of dynamicity in ad hoc and wireless sensor networks and their impact on the efficiency of intrusion detection systems (IDSs). The first aspect is magnitude dynamicity, in which the IDS has to efficiently determine whether the changes occurring in the network are due to malicious behaviors or or due to normal changing of user requirements. The second aspect is nature dynamicity that occurs when a malicious node is continuously switching its behavior between normal and anomalous to cause maximum network disruption without being detected by the IDS. The third aspect, named spatiotemporal dynamicity, happens when a malicious node moves out of the IDS range before the latter can make an observation about its behavior. The first aspect is solved by defining a normal profile based on the invariants derived from the normal node behavior. The second aspect is handled by proposing an adaptive reputation fading strategy that allows fast redemption and fast capture of malicious node. The third aspect is solved by estimating the link duration between two nodes in dynamic network topology, which allows choosing the appropriate monitoring period. We provide analytical studies and simulation experiments to demonstrate the efficiency of the proposed solutions.
Hole-transport barrier and band bending at the indium tin oxide/polymer/p-AlGaN interface (2006)

Nonalloyed Ohmic contacts on p-AlGaN were achieved using a thin polymer film [i.e., poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(4-styrenesulfonate)] as an interlayer for the electronic modification of indium tin oxide/p-AlGaN contacts. The electronic properties were investigated by current-voltage measurements and x-ray photoelectron spectroscopy (XPS). According to XPS measurements, the authors found a slight reduction in the surface band bending of p-AlGaN following PEDOT coating and the disappearance of the barrier for hole transport at indium tin oxide/PEDOT/p-AlGaN interfaces.

Murine Cytomegalovirus (CMV) M33 and Human CMV US28 Receptors Exhibit Similar Constitutive Signaling Activities (2002)

Cellular infection by cytomegalovirus (CMV) is associated with very early G-protein-mediated signal transduction and reprogramming of gene expression. Here we investigated the involvement of human CMV (HCMV)-encoded US27, US28, and UL33 receptors as well as murine CMV-encoded M33 transmembrane (7TM) receptors in host cell signaling mechanisms. HCMV-encoded US27 did not show any constitutive activity in any of the studied signaling pathways; in contrast, US28 and M33 displayed ligand-independent, constitutive signaling through the G protein q (Gq)/phospholipase C pathway. In addition, M33 and US28 also activated the transcription factor NF-kappaB as well as the cyclic AMP response element binding protein (CREB) in a ligand-independent, constitutive manner. The use of specific inhibitors indicated that the p38 mitogen-activated protein (MAP) kinase but not the extracellular signal-regulated kinase 1/2-MAP kinase pathway is involved in M33- and US28-mediated CREB activation but not NF-kappaB activation. Interestingly, UL33-the HCMV-encoded structural homologue of M33-was only marginally constitutively active in the Gq/phospholipase C turnover and CREB activation assays and did not show any constitutive activity in the NF-kappaB pathway, where M33 and US28 were highly active. Hence, CMVs appear to have conserved mechanisms for regulating host gene transcription, i.e., constitutive activation of certain kinases and transcription factors through the constitutive activities of 7TM proteins. These data, together with the previous identification of the incorporation of such proteins in the viral envelope, suggest that these proteins could be involved in the very early reprogramming of the host cell during viral infection.
Prolonged survival of virulent Treponema pallidum (Nichols strain) in cell-free and tissue culture systems (1977)

Survival of Treponema pallidum was found to be prolonged in the presence of tissue culture. Of the 12 cultures studied, cottontail rabbit epithelium (Sf1Ep) supported T. pallidum for the longest time. In horizontal Leighton tubes with reduced medium and an atmosphere of 5% CO2 in N2, the 50% survival time (ST50) was 5 to 6 days for treponemes associated with monolayers of Sf1Ep cells. Comparable cell-free tubes had ST50 values of less than 4 days. In vertical Leighton tubes containing 6 ml of prereduced medium incubated aerobically, gradients of O2 tension and redox potential were established. Attachment and survival of T. pallidum were greatest at a depth of about 10 to 20 mm. Motility was between 70 and 95% in this area throughout the first 14 days of incubation. Occasionally, greater than 50% motility was observed for as long as 21 days. The redox potential and O2 tension in the optimal area of gradient cultures were reproduced by adjusting the medium depth in a shell vial culture system containing cells on a horizontal cover slip. Treponemes associated with the cell monolayer in both gradient and shell vial cultures were still virulent after 21 days in vitro. The dilution of testis extract and the concentration of T. pallidum were found to be important factors in survival of T. pallidum.
The use of miscanthus (Giganteus) as a plant fiber in concrete production (2011)

In this study, it was intended to study the useability of miscanthus, an energy plant in the production of concrete as a plant fiber in the city of Konya which is an agricultural city. It was thought that the concrete that is used in the production of structural elements can be strengthened and produced lighter by the use of miscanthus. The aggregates that are used in the experiments are supplied from Gocu village of Konya. Concrete specimen are produced in three types, namely cubic, cylindirical and beam. A total of 240 experiment specimens are produced from 21 different mixtures, out of these specimens, 105 are cubical with dimensions of 15 × 15 × 15 cm, 63 are cylindrical with dimensions of 15 × 30 cm, and 72 are beam. The granulometry of the aggregate was kept constant, and the concrete was produced with a water-cement ratio of 0.5, having 400, 350 and 300 kg/m3 cement dosages, and with various fiber ratios and styles (grinded, cut and as reinforcement). The produced specimens were kept in water for 28 days. For each different mixture, two cubic specimens are tested for compression on the 7thday, and on the 28th day, compression, splitting and bending tests are performed on three cubical, cylindrical and beam specimens, respectively. Moreover, the unit weight and consistency of fresh concrete, unit weight of hardened concrete and water absorption ratio are determined for every mixture. According to the results obtained from the experiments carried out, using grinded miscanthus as a concrete admixture has increased the strength of concrete in compression, tension and bending by 4 to 28, 9 to 25 and 4 to 9%, respectively. When miscanthus was embedded into the beams as reinforcement, around 2 to 6% increase was observed in the bending strength of the beams.

Assessment of impact of advanced energy transmission fluids on district heating and cooling systems (Phase 1) (1987)

Argonne National Laboratory (ANL), under sponsorship of the US Department of Energy (DOE) Office of Buildings and Community Systems, has embarked upon a comprehensive, long-range program to develop high-performance advanced energy transmission fluids for use in district heating and cooling (DHC) systems. ANL has the lead technical role in this DOE program. These advanced fluids will substantially reduce flow frictional losses and enhance energy transfer. In system enhancement scoping studies conducted by ANL, the fluids yielded potentially significant upfront capital equipment cost reductions by allowing the use of smaller pipes, pumps, heat exchangers, and storage tanks as well as reductions in operational costs. This report presents the first-phase results of assessment of impact of the advanced fluids on DHC systems. Future reports will focus on assessment of impact on hardware performance, capital eqiupment, and operation costs. 9 refs., 30 figs., 2 tab.

The Variation with Temperature of the Photoelectric Effect in Potassium Photoelectric Cells (1924)

Variation of Photoelectric Current with Temperature. The photoelectric current from pure potassium, in highly exhausted cells, is found, contrary to previous belief, to vary with the temperature, and in the sense of the temperature change. The temperature range investigated was from room temperature to the temperature of liquid air; the variation of the photoelectric current with temperature is negligible above 0°C but becomes greater the lower the temperature. The change in photoelectric current is greater the lower the frequency of the exciting radiation, and occurs in both the normal and selective photoelectric effects.Variation of Surface Work Function with Temperature. The variation of photoelectric current with temperature is shown to be in harmony with the supposition that the work function of the surface is altered. Such an alteration of the work function is shown experimentally by the occurrence of a bodily shift along the voltage axis of the voltage-current curve of a photo-sensitive cathode when the potassium, which is changed in temperature, is the anode. It is further checked by the change in the long wave-limit of photoelectric emission of the surface whose temperature is varied. On cooling potassium from +20° to −180°C its work function is increased by about 1/5 volt.
On the formation of epitaxial CoSi2 from the reaction of Si with a Co/Ti bilayer (1995)

In spite of much work, the formation of epitaxial CoSi2 from Ti/Co on (100) Si remains something of a mystery. It has been proposed that epitaxy occurs via the formation of an intermediate phase of CoSi with a (311) preferred orientation. In the absence of sufficient information it is impossible to validate or to invalidate the specific original claim. However, one shows that the formation of preferably oriented CoSi is not a necessary condition for the subsequent growth of epitaxial CoSi2. Careful measurements of diffraction intensities reveal the probable, temporary formation of a metastable form of CoSi2, based on a diamond cubic rather than the usual CaF2 structure.
Highly Efficient Red-Emitting Carbon Dots with Gram-Scale Yield for Bioimaging (2017)

Carbon dots (CDs) are a new class of photoluminescent (PL), biocompatible, environment-friendly, and low-cost carbon nanomaterials. Synthesis of highly efficient red-emitting carbon dots (R-CDs) on a gram scale is a great challenge at present, which heavily restricts the wide applications of CDs in the bioimaging field. Herein, R-CDs with a high quantum yield (QY) of 53% are produced on a gram scale by heating a formamide solution of citric acid and ethylenediamine. The as-prepared R-CDs have an average size of 4.1 nm and a nitrogen content of about 30%, with an excitation-independent emission at 627 nm. After detailed characterizations, such strong red fluorescence is ascribed to the contribution from the nitrogen- and oxygen-related surface states and the nitrogen-derived structures in the R-CD cores. Our R-CDs show good photostability and low cytotoxicity, and thus they are excellent red fluorescence probes for bioimaging both in vitro and in vivo.
Mechanisms of Reactive Oxygen Species–Dependent Downregulation of Insulin Receptor Substrate-1 by Angiotensin II (2005)

Thus, angiotensin II decreases IRS-1 protein levels in VSMCs via Src, PDK1, and reactive oxygen species-mediated phosphorylation of IRS-1 on Ser307 and subsequent proteasome-dependent degradation. These events impair insulin signaling and provide a molecular basis for understanding the clinical observation that angiotensin II type 1 receptor antagonists improve insulin resistance and its associated vasculopathies.
Francisco Romero (1891-1962) (1962)

La primacía filosófica -y aun pudiéramos decir la jefatura-, que Francisco Romero tuvo en la América Latina hasta su muerte, ha sido de reconocimiento unánime por parte de los que han tratado sobre la historia y las vicisitudes de la filosofía en la América de habla española. Tal primacía o jefatura la mantuvo desde su cátedra -abandonada por algún tiempo por razones de índole política-, y desde su amplia y fructuosa labor de publicista. Llegó a la filosofía tarde, (fue militar en su juventud), entusiasmado por las enseñanzas de Alejandro Korn, de quien fue el discípulo predilecto y a quien siempre tuvo reconocimiento de gratitud. La lectura de José Ortega y Gasset fue el otro impulso que recibió en su vocación filosófica. Pero no quiere decir esto que el fi1ósofo argentino, hubiera adherido incondicionalmente tanto a Korn como a Ortega y Gasset. Pues, pronto, por el camino que el pensador español mostró a los pueblos hispanos, se encaminó Romero al estudio y asimilación de la filosofía alemana. La meditación sobre Dilthey, Husserl, Scheler, Hartmann y, en general, sobre todo el pensamiento moderno alemán, desde Kant y Leibniz, le dio la savia que alimentó su propia reflexión. Todas sus obras, desde la primera -la Lógica- denuncian la fuerte influencia alemana. Y fue la filosofía alemana, continuando la labor que Ortega inició en España, la que más divulgó Romero entre los latinoamericanos en sus escritos, en su cátedra -donde formó un numeroso grupo de discípulos- y en la Biblioteca Filosófica que la Editorial Losada puso bajo su dirección.

Recent Advances in Convolutional Neural Networks (2015)

In the last few years, deep learning has led to very good performance on a variety of problems, such as visual recognition, speech recognition and natural language processing. Among different types of deep neural networks, convolutional neural networks have been most extensively studied. Leveraging on the rapid growth in the amount of the annotated data and the great improvements in the strengths of graphics processor units, the research on convolutional neural networks has been emerged swiftly and achieved state-of-the-art results on various tasks. In this paper, we provide a broad survey of the recent advances in convolutional neural networks. We detailize the improvements of CNN on different aspects, including layer design, activation function, loss function, regularization, optimization and fast computation. Besides, we also introduce various applications of convolutional neural networks in computer vision, speech and natural language processing.

Methods to Assay Inhibitors of DNA Gyrase and Topoisomerase IV Activities (2007)

DNA gyrase and DNA topoisomerase (topo) IV are the bacterial targets of coumarin and quinolone antimicrobial agents. Widespread resistance to clinically important antibiotics such as beta-lactams and macrolides has stimulated the development of novel gyrase and topo IV inhibitors especially against Streptococcus pneumoniae and other Gram-positive pathogens. Here, we describe how gyrase and topo IV activities are measured and how inhibitors of these enzymes may be assayed, focusing as a paradigm on DNA supercoiling by S. pneumoniae gyrase, DNA decatenation by S. pneumoniae topo IV, and DNA cleavage by both enzymes. These approaches provide mechanistic insight on inhibitor action and allow identification of dual gyrase/topo IV targeting agents that can minimize the emergence of bacterial resistance.

Spatial Variations in the Fermi Surface of Bi-2212 (2011)

A homojunction-structured amorphous indium gallium zinc oxide (a-IGZO) phototransistor that can detect visible light is reported. The key element of this technology is an absorption layer composed of hydrogen-doped a-IGZO. This absorption layer is fabricated by simple hydrogen plasma doping, and subgap states are induced by increasing the amount of hydrogen impurities. These subgap states, which lead to a higher number of photoexcited carriers and aggravate the instability under negative bias illumination stress, enabled the detection of a wide range of visible light (400-700 nm). The optimal condition of the hydrogen-doped absorption layer (HAL) is fabricated at a hydrogen partial pressure ratio of 2%. As a result, the optimized a-IGZO phototransistor with the HAL exhibits a high photoresponsivity of 1932.6 A/W, a photosensitivity of 3.85 × 10<sup>6</sup>, and a detectivity of 6.93 × 10<sup>11</sup> Jones under 635 nm light illumination.
