Paper-Based Bimodal Sensor for Electronic Skin Applications (2017)

We present the development of a flexible bimodal sensor using a paper platform and inkjet printing method, which are suited for low-cost fabrication processes and realization of flexible devices. In this study, we employed a vertically stacked bimodal device architecture in which a temperature sensor is stacked on top of a pressure sensor and operated on different principles, allowing the minimization of interference effects. For the temperature sensor placed in the top layer, we used the thermoelectric effect and formed a closed-loop thermocouple composed of two different printable inks (conductive PEDOT:PSS and silver nanoparticles on a flexible paper platform) and obtained temperature-sensing capability over a wide range (150 °C). For the pressure sensor positioned in the bottom layer, we used microdimensional pyramid-structured poly(dimethylsiloxane) coated with multiwall carbon nanotube conducting ink. Our pressure sensor exhibits a high-pressure sensitivity over a wide range (100 Pa to 5 kPa) and high-endurance characteristics of 10<sup>5</sup>. Our 5 × 5 bimodal sensor array demonstrates negligible interference, high-speed responsivity, and robust sensing characteristics. We believe that the material, process, two-terminal device, and integration scheme developed in this study have a great value that can be widely applied to electronic skin.
Ablation of Iqgap2 protects from diet-induced hepatic steatosis due to impaired fatty acid uptake (2011)

These observations identify a novel property of the putative GTPase-activating protein IQGAP2 in LCFA uptake in vitro and in vivo, and implicate IQGAP2 in an intracellular signaling pathway necessary for functional fatty acid uptake, lipid processing, and, possibly, glucose homeostasis.
Killing rates exerted by caspofungin in 50 % serum and its correlation with in vivo efficacy in a neutropenic murine model against Candida krusei and Candida inconspicua (2013)

Killing rates (K) of 1-32 µg ml(-1) caspofungin were determined in RPMI-1640 and in 50 % serum using time-kill methodology against three Candida krusei (MICs of all three isolates 0.25 µg ml(-1) in RPMI-1640 and 2 µg ml(-1) in serum) and three Candida inconspicua clinical isolates (MIC ranges 0.06-0.12 µg ml(-1) in RPMI-1640 and 0.25-0.5 µg ml(-1) in serum), against C. krusei ATCC 6258 and against one C. krusei isolate that was resistant to echinocandins (MIC 8 µg ml(-1) in RPMI-1640 and 32 µg ml(-1) in serum). In RPMI-1640, the highest mean K values were observed at 4 (-1.05 h(-1)) and 16 (-0.27 h(-1)) μg ml(-1) caspofungin for C. krusei and C. inconspicua clinical isolates, respectively. In 50 % serum, mean K value ranges at 1-32 and 4-32 µg ml(-1) concentrations for C. inconspicua and C. krusei were -1.12 to -1.44 and -0.42 to -0.57 h(-1), respectively. While K values against C. krusei in RPMI-1640 and 50 % serum were comparable, serum significantly increased the killing rate against C. inconspicua (P<0.0003 for all tested concentrations). In a neutropenic murine model, daily caspofungin at 1, 2, 3, 5 and 15 mg kg(-1) significantly decreased the fungal tissue burden of C. inconspicua in the kidneys (P<0.05-0.001). Against C. krusei, doses of 3, 5 and 15 mg kg(-1) caspofungin were effective (P<0.05-0.01). All effective doses were comparably efficacious for both species. Only the highest 15 mg kg(-1) caspofungin dose was effective even against the echinocandin-resistant C. krusei isolate. In 50 % serum, killing was concentration independent at effective concentrations (≥4 and ≥1 µg ml(-1) for C. krusei and C. inconspicua, respectively), suggesting that the efficacy of dose escalation is questionable. These in vitro results were also supported by the murine model.
Comorbidity and risk of infection among patients with hip fracture: a Danish population-based cohort study (2023)

Comorbidity is an important risk factor for infection up to 1 year after hip fracture surgery.
Control of gene expression by a mobile recombinational switch. (1980)

Transposable recombinational switches may play important roles in the evolution of bacterial populations by increasing flexibility in the control of expression of particular genes and thereby maintaining heterogeneity in clones of cells growing in a uniform environment. Experiments reported here show that Tn5-112, a deletion derivative of kanamycin-resistance transposon Tn5, can function as such a mobile recombinational switch. The internal deletion in Tn5-112 removes transcription termination signals and permits transcription initiated within the element to continue into nearby bacterial genes. Consequently, in one orientation Tn5-112 stimulates distal gene expression, whereas in the other orientation the normal polarity imposed by wild-type Tn5 intervenes and distal gene expression is not stimulated. Because Tn5-112 contains terminal inverted repeats, intramolecular recombination can invert the Tn5-112 element and alter gene expression. Tn5-112 is transposition deficient. Its mobility derives from the recessive nature of the transposition deficiency and, in this study, from the possibility of homologous recombination which permits its placement in either orientation at any site occupied by nother Tn5 element.

A 10-b 500MS/s CMOS cascaded folding A/D converter with a hybrid calibration and a prevision error correction logic (2011)

In this paper, a 10-b 500 MS/s A/D converter (ADC) with a hybrid calibration and a new error correction logic is discussed. The proposed ADC employs a single-channel cascaded folding-interpolating architecture whose folding rate (FR) is 25 and interpolation rate (IR) is 8. In order to overcome the disadvantage of offset error, at the open-loop amplifier, a hybrid self-calibration circuit is proposed. Further, a novel prevision digital error correction logic (DCL) for folding ADC is also described. The ADC prototype using 130 nm 1P6M CMOS has a DNL of ±0.8 LSB and an INL of ±1.0 LSB. The measured SNDR is 52.34-dB and SFDR is 62.04-dBc when the input frequency is 78.15 MHz at 500 MS/s conversion rate. The SNDR of the ADC is 7-dB higher than the same circuit without the proposed calibration. The effective chip area is 1.55 mm and the power dissipates 300 mW including peripheral circuits at 1.2/1.5 V power supply.
Low-Latency and Resource-Efficient Service Function Chaining Orchestration in Network Function Virtualization (2019)

Recently, network function virtualization (NFV) has been proposed to solve the dilemma faced by traditional networks and to improve network performance through hardware and software decoupling. The deployment of the service function chain (SFC) is a key technology that affects the performance of virtual network function (VNF). The key issue in the deployment of SFCs is proposing effective algorithms to achieve efficient use of resources. In this article, we propose an SFC deployment optimization (SFCDO) algorithm based on a breadth-first search (BFS). The algorithm first uses a BFS-based algorithm to find the shortest path between the source node and the destination node. Then, based on the shortest path, the path with the fewest hops is preferentially chosen to implement the SFC deployment. Finally, we compare the performances with the greedy and simulated annealing (G-SA) algorithm. The experiment results show that the proposed algorithm is optimized in terms of end-to-end delay and bandwidth resource consumption. In addition, we also consider the load rate of the nodes to achieve network load balancing.

Stability analysis of single loop control systems with saturation and antireset-windup circuits (1983)

"Reset-windup" appears when regulators with integral action are used with saturating actuators. Antireset-windup (ARW) circuits are in practice used in most standard control equipment today. Their design is based on intuition and simulation. This paper presents analysis of systems with ARW circuits based on nonlinear stability theory. The analysis gives possibilities to compare the performance of different ARW circuits. It predicts the system response adequately without need for extensive simulations.
Effects in 94 GHz Orientation-Selected PELDOR on a Rigid Pair of Radicals with Non-Collinear Axes (2009)

For aromatic organic radicals, pulsed electron-electron double resonance (PELDOR) experiments at high magnetic fields provide information not only about the distance between the paramagnetic species but also about their relative orientation. However, the three-dimensional biradical structure is encoded in a complex pattern of orientation-selected PELDOR traces and the execution of the experiment is generally aggravated by constraints posed by the available hardware and the intrinsically low modulation depth observed. We present a 94 GHz PELDOR experiment performed with a commercial spectrometer and probe heads that permit separation of pump and detection frequencies up to 150 MHz. The setup is employed to examine the orientation selections on a general case of rigid biradicals with non-collinear g axes. The interacting radicals, a tyrosyl radical (Y122·) located in the β2 subunit and an 3-aminotyrosyl radical (NH2Y731·) located in the α2 subunit, are generated by Escherichia coli ribonucleotide reductase with a 3-aminotyrosine (NH2Y) site specifically incorporated into α2 in the presence of cytidine 5′-diphosphate and adenosine 5′-triphosphate. The experimental designs as well as some characteristic features of the observed modulation pattern are discussed.
Evaluation of collection and preservation techniques for urinary cytology. (1981)

To decrease cellular degeneration and promote standardization of methods, the optimal conditions for urinary cytology need to be established. In separate experiments under controlled conditions, dissociated malignant human and benign rat bladder cells were collected and suspended in urine supernate at pH 4.5, 6.0 and 8.0. One-half of each suspension was added to an equal volume of 50% methanol, and aliquots were than examined at 1/2, 2, 24 and 72 hours for preservation of nuclear and cytoplasmic morphology and staining reactions. Cytologic detail was better preserved at pH 4.5, with little difference between fixed and unfixed specimens. Cellular morphology progressively deteriorated with increasing pH and prolonged storage. Fixation after collection improve preservation in urine of pH greater than 4.5. The pH of the first voided morning urine can be lowered by the ingestion of 1 gm of vitamin C at bedtime, improving cellular preservation both before and after voiding. These methods, if widely adopted, will improve the preservation of urine samples and reduce the variations in collection and preservation of specimens at different institutions.
The hydrogen bonding of cytosine with guanine: Calorimetric and 1H‐NMR analysis of the molecular interactions of nucleic acid bases (1987)

Abstract The enthalpy of hydrogen‐bond formation between guanine (G) and cytosine (C) in o ‐dichlorobenzene and in chloroform at 25°C has been determined by direct calorimetric measurement. We derivatized 2′‐deoxyguanosine and 2′‐deoxycytidine at the 5′‐ and 3′‐hydroxyls with triisopropylsilyl groups; these groups increase the solubility of the nucleic acid bases in nonaqueous solvents. Such derivatization also prevents the ribose hydroxyls from forming hydrogen bonds. Consequently, hydrogen‐bond formation in our system is primarily between the bases, and to a lesser extent, between base and solvent, and can be measured directly with calorimetry. To obtain the data on base‐pair formation, we first took into account the contributions from self‐association of each base, and where possible, have determined the Δ H of self‐association. From isoperibolic titration calorimetry, our measured Δ H of C 2 formation in chloroform is −1.7 kcal/mol of C. Our measured Δ H of C:G base‐pair formation in o ‐dichlorobenzene is −6.65 ± 0.32 kcal/mol. Since o ‐dichlorobenzene does not form hydrogen bonds, the Δ H of C:G base‐pair formation in this solvent represents the Δ H of the hydrogen‐bonding interaction of C with G in a nonassociating solvent. In contrast, our measured Δ H of C:G base‐pair formation in chloroform is −5.77 ± 0.20 kcal/mol; thus, the absolute value of the enthalpy of hydrogen bonding in the C:G base pair is greater in o ‐dichlorobenzene than in chloroform. Since chloroform is a solvent known to form hydrogen bonds, the decrease in enthalpic contribution to C:G base pairing in chloroform is due to the formation of hydrogen bonds between the bases and the solvent. The Δ H of hydrogen bonding of G with C reported here differs from previous indirect estimates: Our measurements indicate the Δ H is 50% less in magnitude than the Δ H based on spectroscopic measurements of the extent of interaction. We have also observed that the enthalpy of hydrogen bonding of C with G in chloroform is greater when G is in excess than when C is in excess. This increased heat is due to the formation of C:G n &gt; 1 complexes that we have observed using 1 H‐nmr. Although C:G 2 structures have previously been observed in triple‐stranded polymeric nucleic acids, higher order structures have not been observed between C and G monomers in nonaqueous solvents until now. By using monomers as a model system to investigate hydrogen‐bonding interactions in DNA and RNA, we have obtained the following results: A direct measurement of the Δ H of hydrogen bonding in the C:G complex in two nonaqueous solvents, and the first observation of C:G n &gt; 1 complexes between monomers. These results reinforce the importance of hydrogen bonding in the stabilization of various nucleic acid secondary and tertiary structures.
Effect of Porosity Gradient in Gas Diffusion Layer on Cell Performance With Thin-Film Agglomerate Model in Cathode Catalyst Layer of a PEM Fuel Cell (2011)

A one-dimensional, steady-state, two-phase, isothermal numerical simulations were performed to investigate the effect on cell performance of a PEM fuel cell under non-uniform porosity of gas diffusion layer. In the simulation, the non-uniform porosity of gas diffusion layer was taken into account to analyze the transport phenomena of water flooding and mass transport in the gas diffusion layer. The porosity of the gas diffusion layer is treated as a linear function. Furthermore, the structure of the catalyst layer is considered to be a cylindrical thin-film agglomerate. Regarding the distribution analysis of liquid water saturation, oxygen concentration and water concentration depend on the porosity of gas diffusion layer. In the simulation, the εCG and εGC represent the porosity of the interfaces between the channel and gas diffusion layer and the gas diffusion layer and the catalyst layer, respectively. The simulation results indicate that when the (εCG, εGC) = (0.8, 0.4), higher liquid water saturation appears in the gas diffusion layer and the catalyst layer. On the contrary, when the (εCG, εGC) = (0.4, 0.4), lower liquid water saturation appears. Once the liquid water produced by the electrochemical reaction and condensate of vapor water may accumulate in the open pores of the gas diffusion layer and reduced the oxygen transport to the catalyst sites. This research attempts to use a thin-film agglomerate model, which analyze the significant transport phenomena of water flooding and mass transport under linear porosity gradient of gas diffusion layer in the cathode of a PEM fuel cell.
On forward-adaptive versus forward/backward-adaptive SISO algorithms for Rayleigh fading channels (2001)

Two types of soft-input soft-output (SISO) algorithms have previously been proposed for iterative decoding of concatenated codes applied over fading channels; forward-adaptive algorithms exploit the dependency between the present symbol interval and past symbol intervals, while forward/backward-adaptive algorithms take both the past and the future into account. Numerical results presented for interleaved serially concatenated continuous phase modulation (CPM) over the Rayleigh fading channel indicate that the performance of forward-adaptive algorithms approaches the performance of forward/backward-adaptive algorithms when a long channel-memory depth is exploited.
La inmigración sudamericana en Italia. Efectos sobre el mercado de trabajo (2010)

Las migraciones sudamericanas no son las más numerosas ni las más preocupantes para el gobierno italiano y, quizás por ese motivo, no son las más estudiadas. Sin embargo, desde la década de 1970, las economías sudamericanas, en su mayoría, pasaron de ser receptoras de inmigrantes a expulsoras de su propia fuerza de trabajo, siendo Italia uno de los principales destinos elegidos. En qué trabajan los inmigrantes sudamericanos, cómo y en qué contribuyen a la economía italiana es uno de los interrogantes que busca elucidar este trabajo. El disparador para desarrollarlo fue un afiche de la campaña de gobierno del 2008 de la Liga Nord. En la gráfica se veía un indio Sioux y el texto rezaba: "ellos sufrieron la inmigración primero", haciendo alusión a los efectos negativos de la inmigración. Fue mi interés analizar estos efectos en lo económico y en lo social, restringiéndolo a la población de nuestro subcontinente. El artículo se basa en una experiencia personal de un año de residencia en el país como investigadora, trabajadora flexibilizada, italiana de segunda generación y partícipe de una red de contactos informales que movilizaron este análisis. Se identifica la coexistencia de una división del mercado laboral mediante una complementariedad de trabajos utilizando diferentes formas de acceso, trayectorias, y características en general. Para el segmento que ocupan los nativos se imponen barreras explícitas o no, que se traducen en exclusión. Éstas, se configuran en función de una tipificación que se hace del "otro", en particular los inmigrantes, como no apto, incapaz de realizar esa tarea, o poco "presentable".
Simulating Management Effects on Phosphorus Loss from Farming Systems (2007)

A process-level soil phosphorus (P) model including surface and subsurface components was incorporated into the Integrated Farm System Model (IFSM). Model evaluation indicated that sediment losses were adequately estimated compared to observed data for a corn production system in Texas. In a further evaluation, sediment losses simulated for a wide range in cropping systems and tillage practices were similar to those predicted by the current state-of-the art erosion estimation model (WEPP). Total P losses were accurately predicted when manure P was applied at suitable rates of less than 250 kg P ha-1, but at higher application rates overestimation of P loss was found. Compared to observed data, soluble P loss was underestimated and sediment P loss was overestimated, but this was primarily due to a difference in the differentiation between soluble and sediment P between the modeling and experimental studies. To illustrate the use of the model, IFSM simulations were performed to evaluate the effects of manure handling and tillage systems on P loss from farms in Pennsylvania. For a 100-cow dairy farm, a manure handling strategy that used a 6-month storage and application by injection decreased total P loss by 19% compared to daily surface application, but annual farm net return was decreased by $57/cow. Compared to conventional tillage with a moldboard plow, use of conservation tillage and no-till systems reduced total P loss by 46% and 57%, respectively, with small increases in farm profitability. Reduced tillage increased soluble P loss, suggesting that conservation and no-till systems should be combined with practices such as manure injection to reduce all forms of P loss. The enhanced IFSM containing the soil P model provides a tool for whole-farm analysis of management effects on P loss along with other environmental and economic considerations.
Intensity and polarization of light emitted in slow ion-atom collisions (1996)

We study the intensity and polarization of light emitted during slow ion-atom collisions. We describe the nuclei as moving along classical trajectories while the electronic rearrangement is treated using time-dependent molecular orbitals. The intensity of emitted light is calculated from the diatomic time-dependent dipole. We evaluate the diatomic dipole matrix elements involving 1s, 2s, and 2p traveling atomic orbitals suitable for time-dependent collision studies. We calculate the intensity and the polarization of light emitted in p + H(1s) collisions at kinetic energies from 10 to 1000 eV, for several impact parameters, changing over time. The emitted intensity goes through a maximum as the collision energy increases and lasts between 10 and 1 fs; the polarized light components parallel and perpendicular to the incoming beam direction show pronounced dependences on impact parameters and time. © 1996 John Wiley & Sons, Inc.
Multiaccess interference whitening for TH-BPSK IR-UWB systems (2012)

Interference mitigation using an interference-plus-noise whitening matched filter (WMF) for impulse radio ultrawide bandwidth (IR-UWB) systems in additive white Gaussian noise channels is considered. It is observed that a WMF receiver can improve the error probability performance of IR-UWB systems without adding undue complexity burden to the receiver structure. The signal-to-interference-plus noise ratio (SINR) of the WMF receiver is shown to be superior to that of the conventional matched filter receiver for all the examined values of the signal-to-noise ratio. The SINR gain of the WMF over the CMF is observed to approach 2 dB for large signal-to-noise ratio values.
