Rotating array design for full polarimetric imaging (2016)

In this paper, a novel rotating array topology is proposed for full polarimetric imaging. The rotating array acquires three co-polarized signals at each spatial sampling point. After a simple algebraic manipulation, the full polarimetric signals in the HV polarization basis can be retrieved. Then the traditional polarimetric imaging algorithms can be applied to reconstruct the full polarimetric images. The proposed topology circumvents the polarization variations of the rotating array for signal acquisition. It is very attractive in some applications, for example, ground penetrating radar for tunnel boring machine. Finally, the imaging performances of the proposed array are validated by some numerical experiments.
Enhanced Climate Control of Semi-arid and Arid Greenhouses Equipped with Fogging Systems (2012)

The main objectives were (1) to develop, implement and validate control procedures that would make it possible to maintain year-round air temperature and humidity at levels suitable for crop cultivation in greenhouses operating in arid and semi-arid regions and (2) to investigate the influence of the operational flexibility of the fogging system on the performance of the system. With respect to the development of climate controllers, we developed a new control approach according to which ventilation is used to maintain the enthalpy of the greenhouse air and fogging is used to adjust the humidity ratio inside the greenhouse. This approach is suitable mostly for greenhouses equipped with mechanized ventilation, and in which the air exchange rate can be controlled with enough confidence. The development and initial validation of the controllers were performed in a small experimental greenhouses located at the Agricultural Research Organization and very good tracking were obtained for both air temperature and relative humidity (maximum mean deviations over a 10-min period with constant setpoints lower than 2.5oC and 5% relative humidity). The robust design approach used to develop the controllers made it possible to transfer successfully these controllers to a much larger semi-commercial greenhouse located in the much drier Arava region. After only minimal adjustments, which did not require lengthy dedicated experiments, satisfactory tracking of the temperature and humidity was achieved, with standard deviation of the tracking error lower than 1oC and 5% for temperature and relative humidity, respectively. These results should help promote the acceptance of modern techniques for designing greenhouse climate controllers, especially since given the large variety of greenhouse structures (shape, size, crop system), developing high performance site-specific controllers for each greenhouse is not feasible. In parallel to this work, a new cooling control strategy, which considers the contribution of humidification and cooling from the crop, was developed for greenhouses equipped with natural ventilation. Prior to the development of the cooling strategy itself, three evapotranspiration models were compared in terms of accuracy and reliability. The cooling strategy that has been developed controls the amount of fog introduced into the greenhouse as well as the percentage of vent openings based on the desired vapor pressure deficit (VPD) and enthalpy, respectively. Numerical simulations were used to compare the performance of the new strategy with a constant fogging rate strategy based on VPD, and on average, the new strategy saved 36% water and consumed 30% less electric energy. In addition, smaller air temperature and relative humidity fluctuations were achieved when using the new strategy. Finally, it was demonstrated that dynamically varying the fog rate and properly selecting the number of nozzles, yields additional water and electricity savings.

Randomized Optimal Design of Parallel Manipulators (2008)

This work intends to deal with the optimal kinematic synthesis problem of parallel manipulators under a unified framework. Observing that regular (e.g., hyper-rectangular) workspaces are desirable for most machines, we propose the concept of effective regular workspace, which reflects simultaneously requirements on the workspace shape and quality. The effectiveness of a workspace is characterized by the dexterity of the mechanism over every point in the workspace. Other performance indices, such as manipulability and stiffness, provide alternatives of dexterity characterization of workspace effectiveness. An optimal design problem, including constraints on actuated/passive joint limits and link interference, is then formulated to find the manipulator geometry that maximizes the effective regular workspace. This problem is a constrained nonlinear optimization problem without explicitly analytical expression. Traditional gradient based approaches may have difficulty in searching the global optimum. The controlled random search technique, as reported robust and reliable, is used to obtain an numerical solution. The design procedure is demonstrated through examples of a Delta robot and a Gough-Stewart platform.
Differential Strategies of Continuous Agri-Product Supply Chain Considering Consumer Perception of Eco-Quality (2023)

Considering the influence of the consumers’ perception of eco-quality (CPQ) on the dynamic strategies of the continuous agri-product supply chain, the paper examines a two-stage agri-product supply chain composed of a supplier and a retailer, where the supplier invests in eco-quality improvement and the retailer invests in advertising. Taking the CPQ, eco-quality and goodwill as ternary state variables, the paper formulates joint decision-making models of a continuous agri-product supply chain based on differential game theory. The paper has analyzed equilibrium strategies in decentralized and centralized scenarios, respectively, and further developed an advertising–eco-quality investment cost-sharing contract to coordinate the supply chain. Finally, comparative and numerical analyses have been conducted. The analyses results reveal that consumers’ perceptions of eco-quality and their goodwill preference towards an agri-product encourage the supplier and retailer to improve the eco-quality of the agri-product and the level of advertising. Indeed, the greater the impact of goodwill on demand, the higher level of the supplier’s eco-quality investment and the retailer’s advertising effort, and the higher the profits of the supply chain. The paper also finds that the proposed cost-sharing contract can achieve a Pareto improvement in the continuous agri-product supply chain system. Furthermore, the higher the consumer goodwill preference, the more motivated suppliers and retailers are to cooperate.
Widespread occurrence of bacterial thiol methyltransferases and the biogenic emission of methylated sulfur gases (1987)

A majority of heterotrophic bacteria isolated from soil, water, sediment, vegetation, and marine algae cultures methylated sulfide, producing methanethiol. This was demonstrated with intact cells by measuring the emission of methanethiol with a sulfur-selective chemiluminescence detector, and in cell extracts by detection of sulfide-dependent thiol methyltransferase activity. Extracts of two Pseudomonas isolates were fractionated by gel-filtration and ion-exchange chromatography, and with sulfide as the substrate a single peak of thiol methyltransferase activity was seen in each case. Extracts of several bacterial strains also contained thiol methyltransferase activity with organic thiols as substrates. Thus, S-adenosylmethionine-dependent thiol methyltransferase activities are widespread in bacteria and may contribute to biogenic emissions of methylated sulfur gases and to the production of methyl thioethers.

NMR‐Based Cross‐Link Densities in EPDM and EPDM/ULDPE Blend Materials and Correlation with Mechanical Properties (2022)

Abstract The role of cross‐linking in dictating the microstructural and mechanical properties in ethylene‐propylene‐diene‐monomer rubber (EPDM) and EPDM/ULDPE blends cross‐linked by different sulfur amounts is investigated by solid‐state 1 H time‐domain NMR spectroscopy and tensile‐tests. Analyses of spin‐spin relaxation time ( T 2 ), by combining free‐induction decay (FID), magic‐sandwich echo‐FID, and Hahn‐echo experiments demonstrate a reduction in crystal‐amorphous interface regions of pure ultralow‐density polyethylene (ULDPE) upon curative addition. The blends demonstrate a complete loss of these fractions due to curative‐induced plasticization and solvation by polyethylene segments of EPDM. Cross‐link densities, quantified by the magnitude of residual dipolar coupling constant ( D res ), arising from topological restrictions to segmental motions, are measured by multiple‐quantum experiments. The entanglement‐dominated EPDMs demonstrate a significant reduction in ultimate tensile properties with increasing D res . The analogous blends yield similar D res values up to 0.36 phr of free sulfur. Thereafter, a deviation from the cross‐linking trend of the EPDMs is observed with the blends approaching a cross‐linking limit, thus emphasizing the migration of additives to the amorphous phase of the ULDPE. From the additional contributions of solvation and complex entanglement scenarios in the blends, restoration and even significant enhancement in ultimate tensile strength are achieved. Limitations in applying the popular Mooney–Rivlin analysis are also briefly discussed.
Fault diagnostics in the differential brake control system using the analytical redundancy technique (2003)

This paper presents a novel analytical redundancy technique for fault diagnostics of a differential brake control system. The proposed diagnostic algorithm builds upon open loop and closed loop state estimators to generate residuals and identify failures. By judiciously utilizing the residual information, it is possible to detect faults at the component level rather than at the system level. In addition, robust and adaptive estimators are shown to effectively combat with two perennial nuisances of fault diagnostic algorithms: sensitivity to disturbance and false alarms. Hardware-in-the-loop simulation studies show how reliably the proposed diagnostic algorithm detects faults in the differential brake control system that is expected to play a crucial role in active vehicle safety.
Cost of presumptive source term Remedial Actions Laboratory for energy-related health research, University of California, Davis (1995)

A Remedial Investigation/Feasibility Study (RI/FS) is in progress at the Laboratory for Energy Related Health Research (LEHR) at the University of California, Davis. The purpose of the RI/FS is to gather sufficient information to support an informed risk management decision regarding the most appropriate remedial actions for impacted areas of the facility. In an effort to expedite remediation of the LEHR facility, the remedial project managers requested a more detailed evaluation of a selected set of remedial actions. In particular, they requested information on both characterization and remedial action costs. The US Department of Energy -- Oakland Office requested the assistance of the Pacific Northwest National Laboratory to prepare order-of-magnitude cost estimates for presumptive remedial actions being considered for the five source term operable units. The cost estimates presented in this report include characterization costs, capital costs, and annual operation and maintenance (O&M) costs. These cost estimates are intended to aid planning and direction of future environmental remediation efforts.
Joint Angular and Time Diversity of Multi-Antenna CDMA Systems in Wireless Fading Channels (2011)

In this paper, a multi-antenna based receiver structure for direct sequence code division multiple access (DS/CDMA) system is proposed. The proposed scheme exploits the excellent time resolution of a CDMA RAKE receiver and uses an antenna array beamforming structure to resolve multipath returns in both angular and time domains. A much higher diversity gain than that based only on the time domain diversity can be achieved. This work suggests a new space-time diversity paradigm, namely angular-time diversity, which differs from traditional Alamouti-type space-time coded schemes. The impairments caused by multipath and multiuser interference are analyzed. The performance of the proposed receiver in multipath fading channel is explicitly evaluated. An expression for uncoded system bit error probability is derived. Simulation results show the performance improvement in terms of BER due to the use of multi-antenna in the receiver, and the results illustrate that the multi-antenna based receiver works effectively in resolving multipaths in both angular and time domains to achieve performance improvement due to angular and time diversity gain provided by the multi-antenna system.

Flavor Chemistry (1989)

This chapter gives an overview of new trends and developments in flavor chemistry. One important development was made possible by advances in analytical methodology, that is, the identification of numerous compounds with known flavor characteristics. As more and more compounds are correlated with characteristic flavors, there is a trend to study flavor precursors and to explain how flavor is developed and released. Many of the newest developments in flavor chemistry are in the area of flavor production from plant and animal sources; this trend has come about because of the public's fear of the words "chemical" and "synthetic". In this chapter, words such as these are discussed in terms of the public's perception of them versus a chemist's viewpoint. Another new trend is to understand the chemical reactions involved in the processing and storage of foods in order to bring foods to consumers at optimum acceptability.
Phytotherapie bei chronischen unspezifischen Rückenschmerzen (2014)

Correction to: Phytotherapie bei chronischen unspezifischen RückenschmerzenZeitschrift für Komplementärmedizin 2014; 06(02): 26-30DOI: 10.1055/s-0034-1375943
Organotopic Organization of the Cervical Vagus Nerve (2022)

Abstract Despite detailed characterization of fascicular organization of somatic nerves, the functional anatomy of fascicles evident in human and large mammal cervical vagus nerve is unknown. The vagus nerve is a prime target for intervention in the field of electroceuticals due to its extensive distribution to the heart, larynx, lungs, and abdominal viscera. However, current practice of the approved vagus nerve stimulation (VNS) technique is to stimulate the entire nerve. This produces indiscriminate stimulation of non-targeted effectors and undesired side effects. Selective neuromodulation is now a possibility with a spatially-selective vagal nerve cuff. However, this requires the knowledge of the fascicular organization at the level of cuff placement to inform selectivity of only the desired target organ or function. We imaged function over milliseconds with fast neural electrical impedance tomography and selective stimulation, and found consistent spatially separated regions within the nerve correlating with the three fascicular groups of interest, suggesting organotopy. This was independently verified with structural imaging by tracing anatomical connections from the end organ with microCT and the development of an anatomical map of the vagus nerve. This confirmed organotopic organization. Here we show, for the first time, localized fascicles in the porcine cervical vagus nerve which map to cardiac, pulmonary and recurrent laryngeal function (N=4). These findings pave the way for improved outcomes in VNS as unwanted side effects could be reduced by targeted selective stimulation of identified organ-specific fascicles and the extension of this technique clinically beyond the currently approved disorders to treat heart failure, chronic inflammatory disorders and more.
Text Mining in Cybersecurity (2021)

The growth of data volume has changed cybersecurity activities, demanding a higher level of automation. In this new cybersecurity landscape, text mining emerged as an alternative to improve the efficiency of the activities involving unstructured data. This article proposes a Systematic Literature Review ( SLR ) to present the application of text mining in the cybersecurity domain. Using a systematic protocol, we identified 2,196 studies, out of which 83 were summarized. As a contribution, we propose a taxonomy to demonstrate the different activities in the cybersecurity domain supported by text mining. We also detail the strategies evaluated in the application of text mining tasks and the use of neural networks to support activities involving unstructured data. The work also discusses text classification performance aiming its application in real-world solutions. The SLR also highlights open gaps for future research, such as the analysis of non-English content and the intensification in the usage of neural networks.
A Glucose/O2 Biofuel Cell Using Recombinant Thermophilic Enzymes (2012)

The utilization of recombinant thermophilic enzymes to construct a glucose/O2 biofuel cell (BFC) workable in a wide temperature range with enhanced thermostability using thermophilic pyrroloquinoline quinone (PQQ) dependent glucose dehydrogenase (Tth-PQQGDH, active at even 100°C) and laccase (Tth-Lcs) has been studied to improve the thermostability of BFC. In this glucose/O2 biofuel cell system, electrodes were modified with single-walled carbon nanotubes (SWCNTs) based enzyme films. The resulting electrodes demonstrated enhanced biofuel-cell performance in wide temperature range, which allows them to be used at elevated temperatures.
Microfluidic assay for the on-chip electrochemical measurement of cell monolayer permeability (2019)

Cell monolayers, including endothelial cells lining the vasculature and blood-brain barrier, and epithelial cells lining the lung airways and gut, form a semipermeable barrier across which transport of biomolecules is tightly regulated. The assessment of barrier function is therefore critical in in vitro models of barrier-forming tissues, including microfluidic organ-on-a-chip models. Cell monolayer barrier function is commonly assessed using a fluorescent tracer-based permeability assay in both conventional Transwell and organ-on-a-chip models, but this method requires laborious manual sampling, bulky instrumentation and offline sample processing. In this work, we introduce a novel on-chip microfluidic permeability assay that replaces the traditional fluorescent tracer with an electroactive tracer. Similar to methods such as TEER, the electrochemical permeability assay eliminates the need for manual sampling and complex optical instrumentation. We validated the method by demonstrating close agreement between experimental and numerically-simulated diffusive and convective transport in the microfluidic device. Different electroactive tracers were screened for efficient electron transfer, stability and inertness relative to the cell monolayer. The assay was then used to measure the permeability of endothelial cells cultured under both static and flow culture conditions, and after exposure to a permeability mediator. In summary, the electrochemical permeability assay combines the simplicity of tracer-based permeability methods with the benefits of on-chip integration, which will ultimately facilitate the robust multiparametric characterization of barrier function in microfluidic organs-on-chips.
