High-quality graphene via microwave reduction of solution-exfoliated graphene oxide (2016)

Efficient exfoliation of graphite in solutions to obtain high-quality graphene flakes is desirable for printable electronics, catalysis, energy storage, and composites. Graphite oxide with large lateral dimensions has an exfoliation yield of ~100%, but it has not been possible to completely remove the oxygen functional groups so that the reduced form of graphene oxide (GO; reduced form: rGO) remains a highly disordered material. Here we report a simple, rapid method to reduce GO into pristine graphene using 1- to 2-second pulses of microwaves. The desirable structural properties are translated into mobility values of >1000 square centimeters per volt per second in field-effect transistors with microwave-reduced GO (MW-rGO) as the channel material and into particularly high activity for MW-rGO catalyst support toward oxygen evolution reactions.
Quality of stormwater runoff from paved surfaces of two production sites (2006)

In order to investigate stormwater pollutant loads associated with different anthropic activities and the related pollutant build-up and wash-off processes, two pilot sites have been equipped in the Liguria Region (Italy) for monitoring first flush water quality in a gas station and an auto dismantler facility. TSS, COD, HCtot and heavy metals in dissolved form (Zn, Pb, Cu, Ni, Cd, Cr) have been analyzed during the monitoring campaign (started in February 2004). Stormwater flow and quality data collected in both production sites confirm that EMC values are significantly higher than those observed in an urban site. In the auto dismantler site, the EMC values for TSS, COD and HC largely exceed the standard values (EC 91/271). Contrary to urban surface runoff, scarce correlation between TSS and COD concentrations is observed in runoff from both production sites. The occurrence and nature of the pollutant load connected to first flush flows is discussed by inspection of the M(V)-curves that are provided for all monitored water quality parameters. Significant first flush phenomenon is evidenced for TSS and HC, while such clear behavior doesn't emerge for heavy metals. Hydrologic and climatic characteristics (ADWP, rainfall intensity/depth) appear to scarcely affect the build-up and wash-off processes.
Secure Integrated Sensing and Communication Downlink Beamforming: A Semidefinite Relaxation Approach With Tightness Guaranteed (2023)

Integrated sensing and communication (ISAC) is considered as a key solution toward spectrum congestion in future generations of wireless system. On the other hand, physical-layer security has recently regained attentions as network-layer encryption is becoming more challenging in 5G and beyond. This paper studies a multiuser MIMO beamforming design for ISAC with physical-layer security. Specifically, we consider a power minimization problem with signal-to-interference-plus-noise ratio constraints and with a Cramér-Rao-based sensing performance constraint. The problem is non-convex, but can in principle be approximated by semidefinite relaxation (SDR) which is a convex optimization-based scheme. The main contribution of this paper lies in showing that, with a nearly harmless modification, the problem can be exactly solved by SDR. Prior works showed that the same ISAC problem without physical-layer security can be solved by SDR, but the proof method therein appears to be inapplicable to our secure ISAC problem. Numerical results are presented to illustrate the efficiency of our SDR for solving the secure ISAC problem.

Manganese‐coated IRIS to document reducing soil conditions (2021)

Abstract Iron‐coated indicatorof reduction in soils (IRIS) devices have been used for nearly two decades to help assess and document reducing conditions in soils, and official guidance has been approved for interpreting these data. Interest in manganese (Mn)‐coated IRIS devices has increased because Mn oxides are reduced under more moderately reducing conditions than iron (Fe) oxides (which require strongly reducing conditions), such that they are expected to be better proxies for some important ecosystem services like denitrification. However, only recently has the necessary technology become available to produce Mn‐coated IRIS, and the need is now emerging for guidance in interpreting data derived from Mn IRIS. Ninety‐six data sets collected over a 2‐yr period from 40 plots at 18 study sites among eight states were used to compare the performance of Mn‐coated IRIS with Fe‐coated IRIS and to assess the effect of duration of saturation and soil temperature as environmental drivers on the reduction and removal of the oxide coating. It appears that the current threshold prescribed by the National Technical Committee for Hydric Soils for Fe‐coated IRIS is appropriate for periods when soil temperatures are warmer (&gt;11 °C), but is unnecessarily conservative when soil temperatures are cooler (5–11 °C). In contrast, Mn‐coated devices are particularly useful early in the growing season when soil temperatures are cool. Our data show that when using a threshold of 30% removal of Mn oxide coatings there is essentially 100% confidence of the presence of reducing soil conditions under cool (&lt;11 °C) conditions.
Origen anómalo de la coronaria izquierda en la arteria pulmonar: una serie de casos Anomalous origin of the left coronary artery: a series of cases (2009)

La anomalía de la arteria coronaria izquierda que nace en la arteria pulmonar (ALCAPA por su sigla en Inglés: anomalous left coronary artery from the pulmonary artery), es una enfermedad cardiaca congénita, de baja incidencia y de espectro clínico amplio. La principal forma de presentación es la falla cardiaca por miocardiopatía dilatada. Mediante la revisión de historias clínicas se recolectaron cinco casos consecutivos de ALCAPA, de los que se describen sus cuadros clínicos, así como su diagnóstico y tratamiento. Todos fueron dados de alta en mejores condiciones y asisten a controles periódicos. Estos casos ilustran al origen anómalo de la coronaria izquierda, como diagnóstico diferencial de la miocardiopatía dilatada.<br>Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a congenital cardiac anomaly with low incidence and a broad clinical spectrum. Its main form of presentation is congestive heart failure due to dilated cardiomyopathy. We reviewed clinical histories and collected 5 consecutive ALCAPA cases; its clinical symptoms, diagnosis and treatment were described. All five patients were discharged in better clinical conditions and continue attending to periodic medical follow-up. These cases illustrate the ALCAPA as part of the differential diagnosis of dilated cardiomyopathy.
Optimizing the High-Pass Filter Addition Technique for Image Fusion (2007)

Pixel-level image fusion combines complementary image data, most commonly low spectral-high spatial resolution data with high spectral-low spatial resolution optical data. The presented study aims at refining and improving the High-Pass Filter Additive (HPFA) fusion method towards a tunable and versatile, yet standardized image fusion tool. HPFA is an image fusion method in the spatial domain, which inserts structural and textural details of the higher resolution image into the lower resolution image, whose spectral properties are thereby largely retained. Using various input image pairs, workable sets of HPFA parameters have been derived with regard to high-pass filter properties and injection weights. Improvements are the standardization of the HPFA parameters over a wide range of image resolution ratios and the controlled trade-off between resulting image sharpness and spectral properties. The results are evaluated visually and by spectral and spatial metrics in comparison with wavelet-based image fusion results as a benchmark.
Distributed and Scalable Uplink Processing for LIS: Algorithm, Architecture, and Design Trade-Offs (2022)

The Large Intelligent Surface (LIS) is a promising technology in the areas of wireless communication, remote sensing and positioning. It consists of a continuous radiating surface located in the proximity of the users, with the capability to communicate by transmission and reception (replacing base stations). Despite its potential, there are numerous challenges from an implementation point of view, with the interconnection data-rate, computational complexity, and storage the most relevant ones. In order to address these challenges, hierarchical architectures with distributed processing techniques are envisioned to be relevant for this task, while ensuring scalability. In this work we perform algorithm-architecture codesign to propose two distributed interference cancellation algorithms, and a tree-based interconnection topology for uplink processing. We also analyze the performance, hardware requirements, and architecture trade-offs for a discrete LIS, in order to provide concrete case studies and guidelines for efficient implementation of LIS systems.
Synthesis of AuAg Alloy Nanoparticles from Core/Shell‐Structured Ag/Au (2009)

Monodisperse AuAg alloy nanoparticles (NPs) are made from core/shell Ag/Au NPs through Au and Ag diffusion in oleylamine. The composition of the alloy NPs is controlled by the Au shell thickness and the plasmonic absorptions can be tuned from 520 to 400 nm (see image). These alloy NPs have great potential as optical probes for biosensing and bioimaging, or as catalysts for CO oxidation.
Improvement of soft X-ray generations system based on laser compton scattering (2007)

A compact X-ray source is required in various fields such as biological science and material development. At Waseda University, a table-top size soft X-ray source based on laser Compton scattering has been developed. Using 1047 nm laser beam (Nd:YLF) and 4.6 MeV electron beam generated from a photo-cathode RF-gun, we had already succeeded in generating laser Compton X-rays [1]. The energies are within the "water window" region (250-500 eV) [2] which can be applied to biological studies. For good signal to noise (S/N) ratio and more photons, we remodeled our collision chamber and laser amplifier system. With these modifications, the X-ray photons detected by a micro channel plate (MCP) have increased tenfold to reach 312 /pulse. All the generated photons was estimated to be 3.28 x 104. Moreover, we succeeded in generating soft X-rays stably for more than 10 hours. Good S/N ratio stable X-rays have made it possible to observe the beam-laser interaction precisely.

The Architectural Features and Implementation Techniques of the Multicell CASSM (1979)

The architectural characteristics and the implementation techniques of a context addressed segment sequential memory system called CASSM are described. The system provides hardware support for many database management functions. It offers associative and parallel processing capabilities for the efficient retrieval and manipulation of data in large databases. The hardware is designed mainly to support a hierarchical model for database applications but also contains facilities for supporting a wide range of data searches and operations useful for other nonnumeric data processing applications. The software development of the assembly language CASAL and its assembler, the high-level nonprocedural language CASDAL and its compiler, the interface to the CASSM-user interface computer, etc., have been carried out for the system. The hardware design and implementation techniques have been verified using a one-cell prototype system and a simulator designed for testing the system in the multicell environment. The emphasis of this paper is in the detailed description of the hardware features and techniques used in the multicell CASSM system.
Mbd3, a Component of NuRD/Mi-2 Complex, Helps Maintain Pluripotency of Mouse Embryonic Stem Cells by Repressing Trophectoderm Differentiation (2009)

Embryonic stem cells (ES cells) can differentiate into cells derived from all three germ layers and extraembryonic tissues. While transcription factors such as, Oct4 and Nanog are well known for their requirements for undifferentiated ES cell growth, mechanisms of epigenetic repression of germ layer specific differentiation in ES cells are not well understood. Here, we investigate functions of Mbd3, a component of nucleosome remodeling and histone deacetylation complex (NuRD/Mi-2) in mouse ES cells. We find that compared to wild type ES cells, Mbd3 knockdown cells show elevated RNA expression of trophectoderm markers, including Cdx2, Eomesodermin, and Hand1. In parallel, these cells show an increased acetylation level of histone 3 in promoters of the respective genes, suggesting Mbd3 plays a role in repression of these genes in undifferentiated ES cells. However, these changes are not sufficient for definitive differentiation to trophectoderm (TE) in chimeric embryos. When further cultured in ES medium without LIF or in trophoblast stem (TS) cell medium, Mbd3 knockdown cells differentiate into TE cells, which express Cdx2 and, at later stages, trophoblast lineage specific marker Cadherin 3. These results suggest that Mbd3 helps restrict ES cells from differentiating towards the trophectoderm lineage and is an important epigenetic player in maintaining full pluripotency of mouse ES cells.
DC components in the AC networks containing AC/DC hybrid transmission lines (2016)

The use of hybrid AC/DC overhead transmission lines can help to increase the transport capacity of power lines. But the spatial proximity of DC and AC power circuits in the same right of way leads to the presence of additional DC components in the currents and voltages of the AC line. One of known effects caused by the presence of DC components in the AC networks is the DC saturation of transformers connected to the AC lines. The performance of power and instrument transformers under the influence of DC components may be altered. The influence of DC components on voltage and current transformers for a new planned AC/DC hybrid transmission line is considered in the paper. It is shown that the standard instrument transformers used in the AC power circuits are not significantly affected by the DC components caused by the operation of the DC line. The method for the estimation of the influence of the DC line operation on the instrument transformers in the AC power line is considered in the paper.
Unusual Conductive Behavior of (BEDT-TTF)3Cl2 Hydrate Salts (1996)

Abstract The ion-radical salt (BEDT-TTF)3Cl2*5H2O has been prepared through electro-crystallization using halocarbons as a solvent in the presence of an aliquot of water. The crystal structure was characterized by a multi-layered structure consists of organic layers of a donor stack and inorganic layers of hydrated chloride ions. When the resistivity was measured, the salt showed a rectifying effect. This effect may be caused by the external field-induced structural transition of chloride ions coupled with the change of a hydration scheme.
Synthesis and Antiviral Evaluation of Some 3′‐Fluoro Bicyclic Nucleoside Analogues (2004)

The synthesis of 3'-fluoro analogues of recently discovered highly potent anti-VZV furanopyrimidine deoxynucleosides (BCNAs) is herein reported, for both the alkyl and alkylphenyl series. The compounds are tested against a range of herpes viruses and display poor activity, strongly supporting the notion of the importance of the presence of a 3'-OH for antiviral activity.
Optimization of the av delay in cardiac resynchronization therapy using an implanted hemodynamic monitor (2005)

PURPOSE: Optimization of AV timing is important in heart failure(HF) patients treated with cardiac resynchronization therapy(CRT). An implanted hemodynamic monitor(IHM) can be used for continuous recording of cardiac filling pressures in HF patients. We hypothesized, that the IHM might be helpful in identifying the optimal AVdelay. METHODS:10 patients with heart failure, successfully treated by CRT(InSync III), (LVEF 249%, LVEDD 6411mm) were also implanted with an IHM (Chronicle, Medtronic Inc) that continuously records RV systolic/diastolic pressures and an estimation of the pulmonary artery diastolic pressure (PAD), reflecting left atrial filling pressures. The IHM consists of a memory device and a RV lead with a pressure sensor. First, AV delays were optimized by echo (Ritter method). Then, different AV-delays (50-190 ms) were randomly programmed using steps of 20 ms. The PAD was calculated as a 20s median, 40-60s after programming was changed. A low PAD value was considered optimal. Measurements were repeated 1 week later under the same conditions. The Mann-Whitney U test was used to compare differences within the groups. RESULTS: No adverse events were associated with dual device implant. One patient was excluded due to AF. Using the IHM, a U-shaped curve was obtained, indicating an optimal AV delay slightly longer as compared with echo. Shortening the AV interval resulted in increased PAD (Tab. 1). The relatively low PAD at +60 ms may be associated with fusion beats at longer AV-delays. These observations were consistent in the repeated tests. CONCLUSIONS: The IHM was helpful in identifying the optimal AV-delay in HF patients treated with CRT. In the future, a hemodynamic sensor may be incorporated in CRT devices for long-term recording of filling pressures and allow for hemodynamic device optimization during daily living activities.

STABILIZATION OF THERMAL NEUROCONTROLLERS (2004)

This work deals with the stabilization of neurocontrollers used in thermal applications. The control system can be reduced to an iterative, nonlinear map in time, and its linearization enables a stability analysis. For simple neural networks with few neurons, the eigenvalues can be analytically calculated in terms of the synaptic weights and biases. However, unless care is taken, usual training methods can drive the network to weights and biases such that the corresponding control system is unstable. A modified backpropagation training method is developed here to simultaneously minimize the target error and increase the dynamic stability of the system. Numerical computations are used to analyze the stability of realistic neural networks and their corresponding control systems. The techniques developed are used on an experimental heat-exchanger facility where the stability results are tested and validated.
Genome-wide association mapping reveals novel sources of resistance to northern corn leaf blight in maize (2015)

An association panel including 999 diverse lines was evaluated for resistance to NCLB in multiple environments, and a large number of resistant lines were identified and can be used as reliable resistance resource in maize breeding program. Genome-wide association study reveals that NCLB resistance is a complex trait which is under the control of many minor genes with relatively low effects. Pyramiding these genes in the same background is likely to result in stable resistance to NCLB.

Spectrum Resource Trading and Radio Management Data Sharing Based on Blockchain (2020)

Radio spectrum resource is a scarce resource. How to use the limited spectrum resource to provide users with the maximum communication opportunities is worth further study. In fact, the traditional “command and control” mode of spectrum management is very inefficient in the utilization of spectrum, resulting in a great waste of frequency resources. At the same time, in radio management, it is necessary to set up databases of different services to store different monitoring information. Although the system plays a certain control ability, the radio monitoring records form an island of information, and the information of each service does not circulate, which is not conducive to integrated management. In this paper, based on the current radio spectrum resources in dynamic spectrum sharing method of resource sharing, the spectrum value of trust transfer problem, and the information management system each other information, collaborative management difficulties and other issues, put forward a kind of spectrum sharing method based on blockchain and by business combining intelligent contract database, realize data sharing solution.

Single-Particle Spectroscopy of Gold Nanorods beyond the Quasi-Static Limit: Varying the Width at Constant Aspect Ratio (2010)

We have examined how the surface plasmon resonances (SPRs) of chemically grown gold nanorods with tunable widths and lengths evolve due to phase retardation. For nanorods with diameters d > 30 nm, the aspect ratio is not a sufficient parameter for determining the energy of the longitudinal SPR. To rigorously study the effects of the size, we performed correlated scanning electron microscopy and single-particle spectroscopy on broad gold nanorods that were chemically grown wider (d > 100 nm) and longer while maintaining the surface chemistry and hemispherical end-cap geometry as the slim rods we compared them to (d < 30 nm). At a low aspect ratio of 2.2, the longitudinal SPR of the broad nanorods significantly red-shifted and broadened as the width increased. In addition, broad gold nanorods with d >100 nm displayed higher order plasmon modes that were not observed for slim nanorods of similar aspect ratio. To measure the full spectrum of the largest nanorods, we implemented a new strategy for acquiring single-particle extinction spectra with an extended window of 500−1700 nm by combining a Si CCD camera and an InGaAs array detector. This experiment revealed that changing the width from 25 to 120 nm while maintaining an aspect ratio of only 3.1 caused the longitudinal dipole SPR to red shift 560 nm to 1300 nm. The spectroscopic studies were complemented by theoretical modeling using the discrete dipole approximation. While we found excellent agreement between the measured and predicted maxima of the longitudinal dipole SPR, the intensities of the multipolar plasmon modes were significantly enhanced in the single-particle spectra compared to calculations.
