Microbial degradation of dibenzofuran, fluorene, and dibenzo-p-dioxin by Staphylococcus auriculans DBF63 (1993)

Staphylococcus auriculans DBF63, which can grow on dibenzofuran (DBF) or fluorene (FN) as the sole source of carbon and energy, was isolated. Salicylic acid and gentisic acid accumulated in the culture broth of this strain when DBF was supplied as a growth substrate. Also, the formation of 9-fluorenol, 9-fluorenone, 4-hydroxy-9-fluorenone, and 1-hydroxy-9-fluorenone was demonstrated, and accumulation of 1,1a-dihydroxy-1-hydro-9-fluorenone was observed when this strain grew on FN. On the basis of these results, the degradation pathways of DBF and FN were proposed. The analogous oxidation products of dibenzo-p-dioxin were obtained by incubation with DBF-grown S. auriculans DBF63 cells.

SARSense: Analyzing air- and space-borne C- and L-band SAR backscattering signals to changes in soil and plant parameters of crops (2021)

The upcoming launch of the L-band Synthetic Aperture Radar (SAR) satellite mission Radar Observing System for Europe L-band SAR (ROSE-L) will enable multi-frequency SAR observations when combined with existing C-band satellite missions (e.g., Sentinel-1). Due to the different penetration depths of the SAR signals, multi-frequency SAR offers great potential for field-scale agricultural monitoring and the estimation of soil and plant parameters. The SARSense campaign, conducted between June and August 2019 at the Selhausen agricultural test site near Jülich, Germany, has yielded a comprehensive dataset that includes both air- and space-borne C- and L-band SAR data, extensive in-situ field measurements of soil and plant parameters as well as unmanned aerial systems (UAS)-based multispectral and thermal infrared measurements and cosmic neutron sensing observations. The study provides both, an insight into the strengths and limitations of the acquired dataset as well as an analysis of the different behaviour of C- and L-band backscattering on changing soil moisture and plant parameters for taproot crops and cereals.
Influence of pH in Obtaining Indium Tin Oxide Nanoparticles by Microwave Assisted Solvothermal Method (2018)

A systematic study about synthesis of In1-xSnxO2 (ITO) nanostructured crystals by microwave-assisted solvothermal method is reported. Different solutions using InCl3.4H2O and SnCl4.5H2O precursors in ethylene glycol solvent were prepared in distinct pHs (acid and basic ones). The syntheses were performed at 200 ºC using a heating rate of 50 ºC min-1 and soaking time of 30 minutes. All the synthesized powders were characterized by X-ray Diffraction (XRD) and Rietveld refinement to study the phase evolution as a function of pH. The materials synthesized in the pH ranging between 11.5 and 11.9 were further studied by field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) techniques. As ITO materials have many practical applications due to their transparency in the visible spectrum, UV-Vis spectroscopy analysis was performed to obtain the optical band gap and the respective optical window.

Various types of retrievable tools are available to offer a spectrum of possibilities.
Gap junctional uncoupling plays a trigger role in the antiarrhythmic effect of ischaemic preconditioning (2007)

Uncoupling of GJs prior to ischaemia either by PC or CBX preserves the electrical coupling of cells and results in an antiarrhythmic effect during a subsequent ischaemic insult, indicating that a partial closure of gap junctions may play a trigger role in the protection. In contrast, when CBX is administered in PC dogs the protection both against GJ uncoupling and arrhythmias is markedly attenuated, suggesting that the antiarrhythmic protection, at least in part, is mediated through GJs.
Development of Electrochemical Processes for Nitrene Generation and Transfer (2005)

An electrochemical strategy for running nitrogen-transfer reactions on chemically inert anode surfaces has been developed. The generation and trapping of highly reactive nitrene-transfer reagents can be accomplished under mild conditions on platinum electrodes. The key factor that accounts for the high levels of chemoselectivity in this process is the phenomenon of overpotential. We have found that molecules that are similar in terms of propensity toward oxidation can be differentiated on the basis of their affinity to a given electrode surface. Thereby, reactive species can be selectively generated in the presence of acceptor molecules of interest. Specifically, a wide range of structurally dissimilar olefins can be transformed into the corresponding aziridines in the presence of N-aminophthalimide. Likewise, nitrene generation in the presence of sulfoxides leads to their chemoselective transformation into the corresponding sulfoximines. In this paper we discuss the underlying mechanistic foundation of these reactions.
Oxide Transistors: Metal Oxide Transistors via Polyethylenimine Doping of the Channel Layer: Interplay of Doping, Microstructure, and Charge Transport (Adv. Funct. Mater. 34/2016) (2016)

Enhanced metal oxide (In2O3, IZO, IGZO) transistor performance via polyethylenimine (PEI) doping is demonstrated by J. Yu, M. J. Bedzyk, T. J. Marks, A. Fachetti, and co-workers on page 6179. PEI electron donating capacity combined with charge trapping and variation in the matrix film microstructure contribute, for proper PEI doping levels, to high electron mobility, optimal TFT off-currents, and optimal threshold voltages. This concept is promising for opto-electronic devices based on metal oxide films.
Robust pseudo-random coded colored structured light technique for 3D object model recovery (2008)

The paper discusses a new robust technique for the recovery of pseudo-random coded colored structured light patterns projected on 3D objects in uncooperative colored environments. It uses an iterative grid coloring algorithm that systematically shifts the colors assigned to the PRMVS symbols in order to increase the probability to visually recover elements of the grid projected on multi-colored 3D objects.
Premigration data anti-aliasing for reverse time migration (2015)

For this reason, while the vertical wave-propagation grid is chosen to be dense enough to hold the highest frequency content, a sparser than needed horizontal wave-propagation grid is often used to make high-frequency RTM affordable. As a result, the theoretically alias-free RTM operator suffers from aliasing issues when applied to high-frequency data with steep surface angles. To solve this aliasing issue, we propose first decomposing the input shot gathers of the common-shot RTM into the plane-wave domain using sparse inversion and then applying surface-angle-dependent anti-aliasing filters to individual plane-wave coefficients before transforming them back to the spatial domain. Using 2D synthetic and 3D field data examples, we demonstrate that our method allows RTM to migrate data with a frequency higher than the Nyquist frequency imposed by the horizontal wave-propagation grid without much suffering from aliasing problems.

Synthesis of Potential Glucosidase‐Inhibitors: D‐Xylopyranoside‐5‐spiro‐l′‐cyclopropanes (1990)

Abstract The synthesis of the D‐xylopyranose‐5‐spiro‐1′‐cyclopropane 5 , its methyl α‐D‐glycoside 7 and its benzyl β‐D‐glycoside 13 from D‐glucose is described, and their conformation in solution is discussed. A Königs ‐ Knorr glycosidation of 10 reveals the ionic intermediate of a 1, 1‐(dibromocyclopropyl)carboxonium ion type to be stable against opening of the cyclopropane ring. Very weak inhibition of saccharase was observed for the α‐D‐configurated methyl glycoside 7, whereas the β‐D‐configurated benzyl glycoside 13 did not inhibit emulsin.

Acetaminophen (Paracetamol) Metabolites Induce Vasodilation and Hypotension by Activating Kv7 Potassium Channels Directly and Indirectly (2020)

Direct and indirect activation of Kv7 channels by the APAP metabolite N-acetyl-p-benzoquinone imine decreases arterial tone, which can lead to a drop in blood pressure. Our findings provide a molecular mechanism and potential preventive intervention for the clinical phenomenon of intravenous APAP-dependent transient hypotension.
High-performance large air-gap capacitive wireless power transfer system for electric vehicle charging (2017)

This paper introduces a high-performance large air-gap capacitive wireless power transfer (WPT) module as part of a multi-modular capacitive WPT system for electric vehicle charging. This WPT module utilizes two pairs of metal plates separated by an air-gap as the capacitive coupler, incorporates L-section matching networks to provide gain and reactive compensation, and is driven by a GaN-based inverter operating at 6.78 MHz. The system achieves high efficiency and simplicity by eliminating the need for high-voltage capacitors, and instead utilizes the parasitic capacitances formed between the coupling plates and the vehicle chassis and roadway as part of the matching networks. This paper also presents a comprehensive design methodology for the capacitive WPT system that guarantees high performance by ensuring zero-voltage switching of the inverter transistors, and by selecting matching network component values to maximize efficiency under practical constraints on inductor quality factor and self-resonant frequency. Two prototype 6.78-MHz 12-cm air-gap capacitive WPT systems have been designed, built and tested. The first prototype with 625 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> coupling plate area transfers up to 193 W of power and achieves an efficiency greater than 90%, with a power transfer density of 3 kW/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .

RSSI-based Euclidean Distance algorithm for indoor positioning adapted for the use in dynamically changing WLAN environments and multi-level buildings (2010)

This paper presents positioning algorithms for WLAN environments based on RSSI-fingerprinting and Euclidean Distance (EDA). The adapted algorithms can be used in large and dynamically changing environments and multi-level buildings. Evaluation results show a median location estimation error (MLEE) of 2.12m. The discrete third spatial direction (floor level) was correctly estimated in 99% of cases. The calibration effort may be decreased by a factor of 4, if an increase of MLEE error from 2.12m to 2.69m is tolerated.
A Mup promoter-thymidine kinase reporter gene shows relaxed tissue-specific expression and confers male sterility upon transgenic mice. (1988)

A hybrid gene was made by fusing the 2.2-kilobase 5' promoter region of a mouse group 1 major urinary protein (Mup) gene to the coding region of the herpes simplex virus type 1 thymidine kinase gene (HSV tk) and introduced into the genomes of mice by microinjection. Transgenic G0 males were sterile, or when fertile did not transmit the foreign gene, and the transgenic male descendants of G0 females were also sterile. Seven "lines" were established by breeding from G0 females and their transgenic female descendants. Six lines expressed HSV thymidine kinase activity in the liver, and activity correlated perfectly with the presence of HSV tk RNA. In three of four lines examined, expression was lower in female than in male liver, and in these lines the same sex difference was observed in the rate of run-on transcription of the foreign genes in liver nuclei. When females of one of the sexually dimorphic lines were treated with testosterone, the levels of HSV tk RNA and thymidine kinase activity were increased, although not to male levels. In these aspects of liver expression, and also in a lack of expression in seven other tissues, the hybrid gene exhibits many of the characteristics of an endogenous group 1 Mup gene. However, the gene was also expressed (at high levels) in the preputial gland and testis, two tissues in which Mup genes are not expressed. The gene, when introduced into five of the seven lines, carried a copy of the Escherichia coli supF gene attached beyond the 3' end of the HSV tk gene, but this did not affect the overall expression pattern. All of the lines were male sterile and expressed HSV thymidine kinase in the testis, but one line showed no activity in the liver, and another showed none in the preputial gland. Testicular expression is therefore the likely cause of sterility. Data are described which suggest that the causes of misexpression in the preputial gland and testis are different. Since expression in each tissue occurred in several lines, the structure of the hybrid gene must be responsible in each case. Five intensively studied lines showed at least four consistently different patterns of relative expression in preputial gland, testis, male liver, and female liver. These differences do not correlate in any way with the copy number of the foreign gene in the different lines and must be due to some other aspect of line specific integration.

An Authentication Scheme for Ubiquitous Commerce: A Cognitive Agents Based Approach (2008)

Ubiquitous commerce services are the emerging area in ubiquitous computing. A ubiquitous commerce is a service requested according to the customers personal profile which typically include individual preferences, keeping the technical constraints of mobile device in use and the context of operating environment. An important issue of authentication in ubiquitous commerce platform is, "how does it determine who the mobile customer is, if requests are allowed to come in from various communication channels, devices, and contexts." We propose a transaction-based authentication scheme for ubiquitous commerce service using cognitive agents. The proposed approach of authentication is made less-intrusive to customer by, dynamically deploying authentication challenges based on three factors: ubiquitous commerce transaction sensitivity, context sensitivity, and beliefs on customer behaviors. The method has been simulated with a typical ubiquitous commerce application over in-house established wireless testbed, the results are time efficient and quite encouraging.

Synthesis of 6‐Mono‐6‐deoxy‐β‐cyclodextrins Substituted with Isomeric Aminobenzoic Acids. Structural Characterization, Conformational Preferences, and Self‐Inclusion as Studied by NMR Spectroscopy in Aqueous Solution and by X‐Ray Crystallography in the Solid State. (2004)

The synthesis, purification, and characterization of mono-6-modified-β-cyclodextrins bearing\nN-attached &lt;i&gt;o&lt;/i&gt;-, &lt;i&gt;m&lt;/i&gt;-, and &lt;i&gt;p&lt;/i&gt;-aminobenzoic acids (&lt;b&gt;2&lt;/b&gt;, &lt;b&gt;3&lt;/b&gt;, and &lt;b&gt;4&lt;/b&gt;, respectively) are presented. The structures\nin aqueous solution were investigated using one- and two-dimensional NMR spectroscopy. Detailed\nassignment of the spectra together with intramolecular NOE correlations revealed the way each\nof the isomeric appendages is positioned relative to the macrocyclic cavity. No self-inclusion is\nobserved. The &lt;i&gt;o&lt;/i&gt;-isomer &lt;b&gt;2&lt;/b&gt; turns inward over the top of the primary side and interacts with specific\nprotons of the substituted glucopyranose unit A and those of a neighboring unit. The &lt;i&gt;m&lt;/i&gt;-isomer &lt;b&gt;3\n&lt;/b&gt;displays two conformations, where the substituent resides above the primary side in a tilted manner\nand interacts either with the previous or the next unit. We propose that the carboxyl groups in\nboth &lt;b&gt;2&lt;/b&gt; and &lt;b&gt;3&lt;/b&gt; are localized through H-bonding with one or two, respectively, primary hydroxyl groups\nof the neighboring glucopyranose units. In a similar positioning of the aromatic ring of the &lt;i&gt;p&lt;/i&gt;-isomer\n&lt;b&gt;4&lt;/b&gt;, the hydrophilic carboxyl end is fully exposed to the aqueous environment. The X-ray structure\nof &lt;b&gt;4&lt;/b&gt; shows that the solution conformation has evolved such that in the crystalline state, the aromatic\nmoiety is inserted through its carboxyl part inside another CD where it establishes intermolecular\nH-bonds with inward-turned primary OH groups. Besides this stabilization, &lt;b&gt;4 &lt;/b&gt;forms parallel and\nantiparallel supramolecular chains in the crystal that are additionally stabilized by direct H-bonds.
Optimal Attack against Cyber-Physical Control Systems with Reactive Attack Mitigation (2017)

This paper studies the performance and resilience of a cyber-physical control system (CPCS) with attack detection and reactive attack mitigation. It addresses the problem of deriving an optimal sequence of false data injection attacks that maximizes the state estimation error of the system. The results provide basic understanding about the limit of the attack impact. The design of the optimal attack is based on a Markov decision process (MDP) formulation, which is solved efficiently using the value iteration method. Using the proposed framework, we quantify the effect of false positives and mis-detections on the system performance, which can help the joint design of the attack detection and mitigation. To demonstrate the use of the proposed framework in a real-world CPCS, we consider the voltage control system of power grids, and run extensive simulations using PowerWorld, a high-fidelity power system simulator, to validate our analysis. The results show that by carefully designing the attack sequence using our proposed approach, the attacker can cause a large deviation of the bus voltages from the desired set-point. Further, the results verify the optimality of the derived attack sequence and show that, to cause maximum impact, the attacker must carefully craft his attack to strike a balance between the attack magnitude and stealthiness, due to the simultaneous presence of attack detection and mitigation.
