Pinpointing the distinctive impacts of ten cover crop species on the resident and active fractions of the soil microbiome (2023)

Cover crops are used in agriculture to minimize soil erosion, prevent nutrient leaching and increase soil organic matter content. Cover crops can also be grown to stimulate the soil microbial community to improve soil biological conditions. Despite their widespread use, little is known about the impact of different cover crop species on the composition and activity of the soil microbiome. Here we investigate the effect of distinct cover crop species on the rhizosphere microbiome and characterize both the resident (ribosomal (r)DNA-based) and the potentially active (rRNA-based) fractions of the bacterial, fungal, protist and metazoan communities in the cover crops rhizosphere. We conducted a field experiment using 70-l bottomless containers in which we grew ten monocultures of commonly used cover crop species belonging to five plant families, and an unplanted control treatment (fallow). The total DNA and RNA were extracted from soil and the bacterial, fungal, protistan and metazoan communities were characterized using Illumina MiSeq sequencing. We found that all cover crop species significantly impacted the resident and the potentially active microbial communities in their rhizospheres. Cover crops exerted distinct selection strengths on the native microbial communities. For individual cover crops, the impacts on the resident and the potentially active microbial communities differed while showing similar overall tendencies. Oilseed radish (Brassicaceae) was shown to provoke the strongest microbial shifts, in part attributable to a promotion of the bacterial family Pseudomonadaceae and a repression of Microascaceae in the rhizosphere. Lentil (Fabaceae) induced a widespread stimulation of fungal taxa, including Trichocomaceae and fungal members of the Glomerales order, whereas black oat and hybrid ryegrass (both Poaceae) gave rise to relatively mild changes in the soil microbial communities. Analyses of rRNA-based rhizobiome data revealed that, except for phacelia, all cover crops induced an increase in microbial network complexity as compared to the fallow control. Data presented here provide a broad baseline for the effects of cover crops on four organismal groups, which may facilitate future cover crop selection to advance soil health.
High-power broadband Yb-free clad-pumped EDFA for L-band DWDM applications (2013)

We demonstrated high-power broadband Yb-free clad-pumped erbium-doped fiber amplifier (EDFA) using commercial available low-cost 976 nm multimode diodes. An output power +33 dBm with less than ±1 dB natural gain flatness over a gain bandwidth of 33 nm (1570.3-1603.3 nm) was obtained using a new double-clad erbium-doped fiber which has a large core diameter of 17 μm and low NA of 0.11. The saturated output power, net gain, noise figure, and optical power conversion efficiency of the clad-pumped EDFA were characterized, and system impact of LP11 mode and four-wave-mixing nonlinearity were also evaluated.
Effect of general anesthesia on syncytiotrophoblast plasma membranes from human placenta. (1988)

This investigation shows that a general anesthetic produces similar effects in vivo and in vitro. Anesthesia with a barbituric drug, Thiopental, induces an increase in membrane fluidity and a decrease in the activity of acetylcholinesterase in syncytiotrophoblast plasma membranes (SPM) obtained from placentas after caesarean section. The same effects can be reproduced in vitro after anesthetic addition to the isolated plasma membranes. Morphological and freeze-fracturing studies also suggest that membrane protein components are affected by anesthetics.
The Epstein-Barr virus immediate-early gene product, BMLF1, acts in trans by a posttranscriptional mechanism which is reporter gene dependent (1989)

In DNA cotransfection experiments, the Epstein-Barr virus immediate-early gene product, BMLF1, stimulated the chloramphenicol acetyltransferase (CAT) activity of both latent and productive EBV promoters linked to CAT. This BMLF1-induced increase in CAT activity was out of proportion to the effect on CAT mRNA, suggesting a posttranscriptional mechanism. Furthermore, when growth hormone was used as a reporter gene instead of CAT, BMLF1 no longer functioned. Thus, the BMLF1 effect was reporter-gene dependent. The effect of the BMLF1 gene product does not then appear to be directed at promoter activation, but instead may function to increase the level of an as yet unidentified protein(s) required for Epstein-Barr virus infection.
Reproduction of Reflective and Fluorescent Components using Eight-band Imaging (2015)

We propose a method for relighting fluorescent objects using a multiband image system. Fluorescence is often present in everyday articles and its optical properties make it harder to reproduce than pure reflectance. Decomposing colors into separate fluorescent and reflective components is required for accurate color reproduction. In our method, bi-spectral images are captured using an eight-band camera and an eight-band lighting system for the decomposition. First, spectral reflectance of the object is estimated. Next, the multiband image of the fluorescent components under relighting illumination is generated from the weighted linear combination of the captured fluorescent images. The weight of each band is calculated from the spectral transmittance of each band-pass filter attached to the lighting system, and the spectral power distributions (SPD) of the illumination during image capturing and relighting. Finally, a relighted image is reproduced by composing reflective and fluorescent component images. Experimental evaluations show that the spectral reflectance and SPD of fluorescent components are accurately estimated and relighting images are well reproduced.
Embryonal Masses Induced at High Temperatures in Aleppo Pine: Cytokinin Profile and Cytological Characterization (2020)

Aleppo pine (Pinus halepensis Mill.), a native species of the Mediterranean region, has been suggested as a species that when introduced in degraded areas could facilitate the long-term colonization and expansion of late-successional species. Due to climate changes, plants need to withstand extreme environmental conditions through adaptation and changings in developmental pathways. Among other paths, plants undergo changes in developmental pathways controlled by phytohormones. At the same time, somatic embryogenesis has been widely used as a model to understand the mechanisms involved in plant response to different stresses. In this study, in order to induce a strong effect of temperature stress on plants regenerated from somatic embryos, higher temperatures (40 °C for 4 h, 50 °C for 30 min, and 60 °C for 5 min) than the control (23 °C) were applied during the induction stage of somatic embryogenesis in Pinus halepensis. A morphological characterization of the embryogenic cultures showed small differences in the number of starch grains, lipid bodies, and phenolic compounds between treatments. Results showed that high temperatures (60 °C) led to higher rates at the maturation stage of somatic embryogenesis when compared to the control (23 °C), strengthening the productivity through the increase in the number of somatic embryos obtained. Finally, analysis of endogenous concentration of cytokinins showed that different conditions applied during the initiation phase of somatic embryogenesis led to different hormonal profiles; isoprenoid cytokinins showed a clear defined pattern with the higher total hormone concentration being found in embryonal masses induced at 50 °C for 30 min, while different aromatic cytokinins presented different individual responses to the treatments applied. These differences corroborate the idea that cytokinins could be potential regulators of stress–response processes during initial steps of somatic embryogenesis.
MSE-Based Transceiver Designs for Full-Duplex MIMO Cognitive Radios (2015)

We study two scenarios of full-duplex (FD) multiple-input-multiple-output cognitive radio networks: FD cognitive ad hoc networks and FD cognitive cellular networks. In FD cognitive ad hoc networks (also referred as interference channels), each pair of secondary users (SUs) operate in FD mode and communicate with each other within the service range of primary users (PUs). Each SU experiences not only self-interference but also interuser interference from all other SUs, and all SUs generate interference on PUs. We address two optimization problems: one is to minimize the sum of mean-squared errors (MSE) of all estimated symbols, and the other is to minimize the maximum per-SU MSE of estimated symbols, both of which are subject to power constraints at SUs and interference constraints projected to each PU. We show that these problems can be cast as a second-order cone programming, and joint design of transceiver matrices can be obtained through an iterative algorithm. Moreover, we show that the proposed algorithm is not only applicable to interference channels but also to FD cellular systems, in which a base station operating in FD mode simultaneously serves multiple uplink and downlink users, and it is shown to outperform HD scheme significantly.

A Case Study in the Development of Collaborative Customer Care: Concept and Solution. (1999)

We describe the concept of Web-based collaborative customer care and our experience designing a proof of concept solution for a real-world customer. The paper describes the requirements for collaborative customer care and the features of the implemented system. They differ from the requirements for workgroup collaboration due to differences in users, tasks and goals, and context of use. We also discuss the design process with a focus on how particular design activities revealed key requirements for integrating collaborative customer care into the business&amp;apos; organizational and information systems infrastructures. We found the use of concrete methods and artifacts to be effective techniques for discovering design requirements for this new technology. KEYWORDS collaboration, customer care, QOC, system design, scenarios, Web. 1. INTRODUCTION Synchronous collaboration tools have typically been designed to support workgroups. For example, consider shared writing tools (Ellis 1991, Olson 19...
Immune Responses in Macaques to a Prototype Recombinant Adenovirus Live Oral Human Papillomavirus 16 Vaccine (2014)

Immunization with human papillomavirus (HPV) L1 virus-like particles (VLPs) prevents infection with HPV. However, the expense and logistical demands of current VLP vaccines will limit their widespread use in resource-limited settings, where most HPV-induced cervical cancer occurs. Live oral adenovirus vaccines have properties that are well-suited for use in such settings. We have described a live recombinant adenovirus vaccine prototype that produces abundant HPV16 L1 protein from the adenovirus major late transcriptional unit and directs the assembly of HPV16 VLPs in tissue culture. Recombinant-derived VLPs potently elicit neutralizing antibodies in mice. Here, we characterize the immune response to the recombinant after dual oral and intranasal immunization of pigtail macaques, in which the virus replicates as it would in immunized humans. The immunization of macaques induced vigorous humoral responses to adenovirus capsid and nonstructural proteins, although, surprisingly, not against HPV L1. In contrast, immunization elicited strong T-cell responses to HPV VLPs as well as adenovirus virions. T-cell responses arose immediately after the primary immunization and were boosted by a second immunization with recombinant virus. T-cell immunity contributes to protection against a wide variety of pathogens, including many viruses. The induction of a strong cellular response by the recombinant indicates that live adenovirus recombinants have potential as vaccines for those agents. These studies encourage and will inform the continued development of viable recombinant adenovirus vaccines.

RSR13, a Synthetic Allosteric Modifier of Hemoglobin, Improves Myocardial Recovery Following Hypothermic Cardiopulmonary Bypass (1999)

These results indicate that in the setting of hypothermic cardiopulmonary bypass, RSR13 improves recovery of myocardial mechanical and metabolic function compared with standard hypothermic BC. Findings from this study suggest that RSR13-BC, by decreasing hemoglobin oxygen affinity, improves oxidative metabolism and preserves cellular morphology, resulting in significantly improved contractile recovery on reperfusion.

<title>Microfabricated devices for sizing DNA and sorting cells</title> (1998)

We have microfabricated devices to size and sort microscopic biological objects, ranging from cells to single molecules of DNA. Sizing is accomplished by fluorescent excitation and detection. The devices are fabricated in a silicone elastomer using a replica method. Single molecules of DNA have been sized to 10 percent accuracy, and manipulation of E. Coli cells has been demonstrated.
Influence of depressed-index outer ring on evanescent tunneling loss in tapered double-cladding fibers (2008)

A tapered fiber with a depressed-index outer ring is fabricated and dispersion engineered to generate a widely tunable (1250-1650 nm) fundamental-mode leakage loss with a high cutoff slope (-1.2 dB/nm) and a high attenuation for stop band (>50 dB) by modification of both waveguide and material dispersions. The higher cutoff slope is achieved with a larger cross angle between the two refractive index dispersion curves of the tapered fiber and surrounding optical liquids through the use of depressed-index outer ring structures in double-cladding fibers.
Influence of surface properties and antecedent environmental conditions on particulate-associated metals in surface runoff (2020)

Particulate-associated trace metals have been regarded as an important pollution source for urban surface runoff. Cd, Pb, Cu, Zn and total solids (TS) washed off two different surfaces (low-elevated facade and road surfaces) under two kinds of antecedent environmental conditions (dry and snow-melting) were determined in this study. Wet-vacuuming sweeping (WVS) and surface washing (SW) methods, representing the maximum pollution potential and common rainfall-induced wash-off condition respectively, were used to collect the particulate matters. The result shows that the wash-off concentrations of trace metals were found in the order of Cd (2.28 ± 2.08 μg/l) < Pb (435.85 ± 412.61 μg/l) < Cu (0.93 ± 0.61 mg/l) < Zn (2.52 ± 2.30 mg/l). The snow-melting process had a considerable influence on the wash-off concentrations of the trace metals on both road and facade surfaces. It reduced >38% and >79% of metals and TS concentrations in the facade surface and road surface runoff respectively. The wash-off concentrations of Cd, Cu, and Zn on the road surface 45-780% higher than those on the facade surfaces. The sensitivity analysis based on the Bayesian network indicates that the wash-off concentrations of metals were mainly dependent on the antecedent environmental conditions or the surface properties while the sampling methods had a minor influence. Therefore, to accurately model the pollutant migration in the surface runoff requires an improving method considering different surfaces and antecedent environment conditions.

Results from an x-band synthetic aperture radar collection in Antarctica (2007)

In January, 2006, the New York Air National Guard requested that Sandia National Laboratories develop an X-band synthetic aperture radar to use for an experiment to detect crevasses in Antarctica. Sandia provided a MiniSAR radar that was modified to operate at X-band. Data was collected with this system in the Antarctic summer of 2006. The results from this data collection are presented in this paper.
Magnetic Field Analysis of Asymmetric, High-Pass Imaging Structures Based on Theoretical Current Distributions (1994)

Magnetic flux density contours developed by quadraturedriven, Nuclear Magnetic Resonance (NMR) radio frequency coils are investigated. Experimental data is obtained from symmetric and asymmetric structures of both circular and elliptical cross section. Said field profiles are analytically analyzed via a voltage- current transmission matrix model, utilizing an equivalent lumped- element circuit representation and yielding acceptable correlation with experimental data. In the worst case, for the elliptical asymmetric structure, the predicted magnetic flux density values agree to within 23.5% at most for measured values of the NMR flip angle . In the best case, for the circular symmetric structure, the predicted magnetic flux density values agree to within 7.4% at most for measured values of the NMR flip angle.
Electrical tree inhibition by voltage stabilizers (2012)

Electrical treeing is one of the main degradation mechanisms in polymer dielectrics at highly divergent electric fields and can, if initiated, cause dielectric breakdown as soon as an electrical tree channel has bridged the insulation. One way of increasing resistance to electrical treeing is the addition of certain organic additives such as polycyclic aromatic compounds or benzophenone-like structures. These additives act as voltage stabilizers that are believed to capture high energy electrons and dissipate their energy, preventing degradation of the polymer matrix by the impact of “hot electrons”. In this study, a benzil type compound is evaluated as voltage stabilizer in a superclean cross-linked polyethylene compound used for high voltage cable applications. The stabilizing effect of the additives is measured using test objects of wire-plane electrode geometry in ramped AC voltage experiments. For determining tree initiation conditions, optical detection is used and correlated to voltage measurements. In this way, the initiation voltage of each single tree is determined. Results show that the investigated voltage stabilizer raises the electrical tree inception level significantly. The stabilizing effect is dependent on voltage ramp rate and using a lower ramp rate results in a more pronounced effect of the stabilizer.

High Temperature Operation AlGaN/GaN HFET with a low on-state resistance, a high breakdown voltage and a fast switching capacity (2006)

Improved characteristics of an AlGaN/GaN HFET are reported. We introduced new fabrication processes using Ti/AlSi/Mo ohmic electrode and a low refractive index SiN <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> to decrease the contact resistance and gate leakage current. The AlGaN/GaN HFET showed low a specific resistance of 6.3 mOmegacm <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> and a high breakdown voltage of 750 V. We investigated switching characteristics of an AlGaN/GaN HFET. The small turn-on delay of 7.2 nsec, which was 1/10 of Si MOSFET, was measured. The switching operation of the HFET showed no significant degradation up to 225degC
Alkali-induced crumpling of Ti3C2Tx(MXene) to form 3D porous networks for sodium ion storage (2018)

We present a novel strategy for constructing three-dimensional (3D) porous Ti3C2Tx (MXene) networks by alkali-induced crumpling of Ti3C2Tx nanosheets. The 3D porous Ti3C2Tx networks display high capacity and outstanding rate performance as anode materials for sodium-ion batteries.
A Single-Input/Binaural-Output Antiphasic Speech Enhancement Method for Speech Intelligibility Improvement (2021)

Improving intelligibility of a speech signal of interest from its observations (with a single microphone) corrupted by additive noise has long been a challenging problem. Motivated by important findings achieved in the psychoacoustic field, we propose in this work a deep learning based method to render the noise and desired speech in the perceptual space such that the perception of the desired speech is least affected by the noise. Specifically, we adopt the temporal convolutional network (TCN) based structure to map the single-channel noisy observations into two binaural signals, one for the left ear and the other for the right ear. The TCN is trained in such a way that the desired speech and noise will be perceived to be in opposite directions when the listener listens to the binaural signals. This antiphasic binaural presentation enables the listener to better distinguish the desired speech from the annoying noise for improved speech intelligibility. The modified rhyme test is performed for evaluation and the results justify the superiority of the proposed method for speech intelligibility improvement.
