Adaptive electric potential sensors for smart signal acquisition and processing

Current applications of the Electric Potential Sensor operate in a strongly (capacitively) coupled limit, with the sensor physically close to or touching the source. This mode of operation screens the sensor effectively from the majority of external noise. To date however the full capability of these sensors operating in a remote mode has not been realised outside of a screened environment (Faraday cage). This paper describes the results of preliminary work in tailoring the response of the sensors to particular signals and so reject background noise, thereby enhancing both the dynamic range and signal to noise ratio significantly.
Design, synthesis and cytotoxic evaluation of 2-amino-4- aryl-6-substituted pyridine-3,5-dicarbonitrile derivatives

Purpose: To synthesize novel pyridine derivatives and evaluate their efficiency as potent inhibitors of cyclin dependent kinase 2 (CDK2) enzyme for cancer therapy.Methods: Pyridine scaffold were synthesized using one-pot multicomponent condensation reaction of arylidine with different primary amines. The cytotoxic potential of the new compounds was assessed using various cell lines. Furthermore, molecular docking studies based on the crystal structure of CDK2 was carried out to determine the possible binding modes that influence the anticancer activities.Results: The results indicate that one-pot multicomponent reaction generated a series of functionalized pyridines with good yield. In vitro cytotoxicity study revealed superior cytotoxicity of the designed compounds against prostate and cervical cancer cell lines compared to 5-fluorouracil (standard anticancer compound) with half-maximal inhibitory concentration (IC50) values of 0.1 – 0.85 and 1.2 –74.1 μM, respectively. Finally, molecular modeling simulation of the newly synthesized compounds showed that they fit well and are stabilized into CDK2 active site via hydrogen bonding and hydrophobic interactions.Conclusion: The results indicate that the newly synthesized pyridine can exert potent anticancer activity presumably via inhibition of CDK2. However, this will need to be confirmed in in vivo studies.
Analysis into intentional electromagnetic interference of electronic systems

Electronic systems are susceptible to electromagnetic wave interaction. These waves generate undesired cunents and voltages in electronic circuits, which are added to the n0n11al signals and at a certain level will interfere with the nonnal operation of the circuit. A new threat for military and civil systems, in the higher frequency spectrum, are high power microwave (HPM) and ultra wide-band (UWB) sources. These sources generate electromagnetic fields, ranging from kilowatts to gigawatts, in short pulses with fast rise times. Intense electromagnetic fields are known to cause damage in many electronic systems. In general, the frequencies range from 200 MHz up to 5 GHz. An attack with this kind of systems is an example of intentional electromagnetic interference (IEMI). HPM and UWB waveforms are not easy to predict. Cunently there is no standard for design, testing and countermeasures available. Research is the only way to provide sufficient insight into the coupling of these signals and interaction in electronic systems. High power microwave energy can penetrate electronic systems through the "Front door" (antennas) or the "Back door" (cables and apertures). Permanent damage to electronic systems is generally caused by them1al effects or electrical breakdown in the circuits. It can be concluded that electronic is sensitive for the energy contents and / or peak value of the HPM field. To develop protection measures it is very important to know the sensitivity of electronic equipment for these kind of signals. When a trend is noted this can be used for setting up HPM test methods at appropriate field levels. In order to study coupling into systems, appropriate models are used to model the housing of a real piece of 19" IT equipment to determine the possible resonant frequencies. The housing is modeled as an enclosure with two small apertures. The frequencies which are calculated analytically and defined in the frequency and time domain measurements are very close. The resonance frequencies calculated by using FDTD are a somewhat lower. An existing system, on which the model is based, is tested for susceptibility. Some frequencies of interference are lower than the numerical and measured resonance frequencies. An impOliant issue for future research is to investigate the cause of that difference. When using plane-wave excitation within FDTD, by using the scattering fommlation, it has been recognized that numerical etTors were present. FlIliher analysis is recommended. It is observed that the amplitude (of the resonance frequencies) depends on
A Probabilistic Inventory Analysis of Biomass for the State of Texas for Cellulosic Ethanol

A Probabilistic Inventory Analysis of Biomass for the State of Texas for Cellulosic Ethanol. (May 2009) Matthew Alan Gleinser, B.S., Texas A&M University, College Station Chair of Advisory Committee: Dr. James Richardson Agricultural and forestry wastes for the use of creating cellulosic ethanol were inventoried for each county in Texas. A simple forecast was created for each of the agricultural wastes and then a multivariate empirical distribution was used to simulate the range of biomass available by county and district. The probability that a district could support a 25, 50, 75, or 100 million gallon cellulosic ethanol plant is estimated from the Monte Carlo simulation results. Biomass in Texas is concentrated in the Northern and Eastern areas of the state. The areas of South and West Texas have little to no biomass available to use for cellulosic ethanol. The North East, South East, and Upper Coast districts include forestry waste that increase the amount of available biomass. With 100 percent certainty the North East and South East districts can support four 100 million gallon cellulosic ethanol plants each. The research found that there is more than enough biomass to support numerous cellulosic ethanol plants in Texas, and decision makers can use the results of this study to identify regions of low and high risk for available biomass from agricultural and forestry waste.
Influence of nitrogen on the growth and yield of cotton under salinity stress

Abstract Mineral nutrient supplementation is a vital strategy to detoxify the lethal effects of salinity stress induced by sodium chloride. To explore the role of mineral nutrition (nitrogen), a hydroponic experiment was carried out for the whole growing season to find out the effects of different levels of nitrogen (0.25, 2.5, and 5 mmol·L−1 N) on the growth and yield of upland cotton genotypes (salt-tolerant, ST, Z9807 and salt-sensitive, SS, Z0102) exposed to salt stress (200 mmol·L−1 NaCl). Salt stressed cotton genotypes exhibited a marked reduction in growth traits and dry biomass accumulation. Nitrogen confirmed its positive role by ameliorating the detrimental effects of salt stress on significant levels when supplied at 2.5 mmol·L−1 as compared to 5 mmol·L−1. Nitrogen application at 5 mmol·L−1 concentration suggestively increased all the morphological and physiological traits under the non-saline environment. Nitrogen at 2.5 mmol·L−1 progressively improved the root morphology of both tolerant and sensitive genotypes and ensured better nitrogen uptake under saline conditions. Besides, nitrogen supplementation at 2.5 mmol·L−1 proved beneficial in positively enhancing the photosynthetic pigment biosynthesis (3.05- and 4.14-fold for TChl, 1.72- and 2.06-fold for Car, and 2.84- and 2.96-fold for An for ST and SS), nitrogen content (9.26- and 11.19- fold for ST and SS), and the seed cotton yield (7.20 times in ST and 7.25 times in SS) of cotton genotypes as compared to the salinity treatment alone. Conclusively, the study results evidenced that nitrogen at moderate concentration can be advantageous in preventing NaCl induced damage.

Complete genome sequencing and comparative genomic analysis of Lactobacillus acidophilus C5 as a potential canine probiotics

Abstract Lactobacillus acidophilus is a gram-positive, microaerophilic, and acidophilic bacterial species. L. acidophilus strains in the gastrointestinal tracts of humans and other animals have been profiled, but strains found in the canine gut have not been studied yet. Our study helps in understanding the genetic features of the L. acidophilus C5 strain found in the canine gut, determining its adaptive features evolved to survive in the canine gut environment, and in elucidating its probiotic functions. To examine the canine L. acidophilus C5 genome, we isolated the C5 strain from a Korean dog and sequenced it using PacBio SMRT sequencing technology. A comparative genomic approach was used to assess genetic relationships between C5 and six other strains and study the distinguishing features related to different hosts. We found that most genes in the C5 strain were related to carbohydrate transport and metabolism. The pan-genome of seven L. acidophilus strains contained 2,254 gene families, and the core genome contained 1,726 gene families. The phylogenetic tree of the core genes in the canine L. acidophilus C5 strain was very close to that of two strains (DSM20079 and NCFM) from humans. We identified 30 evolutionarily accelerated genes in the L. acidophilus C5 strain in the ratio of non-synonymous to synonymous substitutions (dN/dS) analysis. Five of these thirty genes were associated with carbohydrate transport and metabolism. This study provides insights into genetic features and adaptations of the L. acidophilus C5 strain to survive the canine intestinal environment. It also suggests that the evolution of the L. acidophilus genome is closely related to the host’s evolutionary adaptation process.
In diverse conditions, intrinsic chromatin condensates have liquid-like material properties

Eukaryotic nuclear DNA is wrapped around histone proteins to form nucleosomes, which further assemble to package and regulate the genome. Understanding of the physical mechanisms that contribute to higher order chromatin organization is limited. Previously, we reported the intrinsic capacity of chromatin to undergo phase separation and form dynamic liquid-like condensates, which can be regulated by cellular factors. Recent work from Hansen, Hendzel, and colleagues suggested these intrinsic chromatin condensates are solid in all but a specific set of conditions. Here we show that intrinsic chromatin condensates are fluid in diverse solutions, without need for specific buffering components. Exploring experimental differences in sample preparation and imaging between these two studies, we suggest what may have led Hansen, Hendzel, and colleagues to mischaracterize the innate properties of chromatin condensates. We also describe how liquid-like in vitro behaviors can translate to the locally dynamic but globally constrained movement of chromatin in cells.
Towards greater understanding of success and survival of lean systems

The purposes of this research are to remove some of the confusion surrounding the characterisation of lean systems; to delve deeper into the human issues associated with lean; and to explore the complexity of an established lean system to identify issues which affect its success and ongoing continuance. Using the mixed methods of literature analysis, semi-structured interviews and document analysis, we examine the lean implementation in one site of an international car manufacturer. We claim several contributions for the work. First, we produce a literature-based taxonomy defining the core dimensions of lean – this gives managers a clear roadmap for lean implementation. A second contribution is a detailed delineation of the human issues of lean, from which managers can follow our set of themes to guide their managerial efforts. Finally, we provide insights into the inner workings of a lean system showing several examples of the delicate balances and tensions which exist. Perhaps none is as significant as the issue of its long term survival, which our findings suggest may be at risk. This serves as a warning signal to managers to be on constant lookout for signs of faltering or failure.
On the stability of complex ions in ionic liquid Ion sources

Ionic liquids are molten salts at room temperature that consist of positive and negative ions. These liquids can be used in electrosprays to produce ion beams. Ionic liquid ion source (ILIS) beams typically consist of single ions and solvated ions. It has been observed that solvated ions are not always stable and can break up into lighter ions midflight. Past experiments show that the stability of solvated ions depends on the molecular composition of the ionic liquid. Based on these results, it has been hypothesized that the stability of solvated ions increases with increasing molecular complexity of the ions. The focus of this work is to test this hypothesis by characterizing ionic liquids of different molecular complexities under controlled conditions. A time of flight mass spectrometer and a retarding potential analyzer were developed specifically for this purpose. The ion beam composition and energy distribution were measured at various temperatures and source voltages for each ionic liquid. With some exceptions, the observed trend was in agreement with the results of past experiments and with the hypothesis. The exceptions to the expected trend may have resulted from the limitations of the detectors. The data from this work can be used to test the hypothesis with moderate confidence. Future study requires improvements to the detectors, namely the retarding potential analyzer, so that the hypothesis can be evaluated more conclusively. Thesis Supervisor: Paulo C.

Reactive Navigation of an Unmanned Aerial Vehicle With Perception-Based Obstacle Avoidance Constraints

In this article, we propose a reactive constrained navigation scheme, with embedded obstacles avoidance for an unmanned aerial vehicle (UAV), for enabling navigation in obstacle-dense environments. The proposed navigation architecture is based on a nonlinear model predictive controller (NMPC) and utilizes an onboard 2-D LiDAR to detect obstacles and translate online the key geometric information of the environment into parametric constraints for the NMPC that constrain the available position space for the UAV. This article focuses also on the real-world implementation and experimental validation of the proposed reactive navigation scheme, and it is applied in multiple challenging laboratory experiments, where we also conduct comparisons with relevant methods of reactive obstacle avoidance. The solver utilized in the proposed approach is the optimization engine (OpEn) and the proximal averaged Newton for optimal control (PANOC) algorithm, where a penalty method is applied to properly consider obstacles and input constraints during the navigation task. The proposed novel scheme allows for fast solutions while using limited onboard computational power, which is a required feature for the overall closed-loop performance of a UAV and is applied in multiple real-time scenarios. The combination of built-in obstacle avoidance and real-time applicability makes the proposed reactive constrained navigation scheme an elegant framework for UAVs that is able to perform fast nonlinear control, local path planning, and obstacle avoidance, all embedded in the control layer.
Electromechanical impedance based debond localisation in a composite sandwich structure

An electromechanical impedance (EMI) based structural health monitoring (SHM) approach is proposed for the localisation of skin-core debonds in composite sandwich structure (CSS). Towards this, laboratory experiments and numerical simulations of EMI in a CSS with core to bottom face-sheet debond have been carried out using a network of piezoelectric transducers (PZTs). The frequency-domain analysis of the registered EMI signals shows that the presence of inter-facial debonds in the CSS significantly influences the conductance magnitudes of the registered EMI data. It was also noticed that the conductance magnitudes of the signals are dependent on the debond-to-PZT distances. In all the study cases, an agreement between the simulation and experimental results is observed. Eventually, a simulated SHM approach is proposed that uses a debond detection algorithm to calculate the changes in conductance magnitudes to effectively locate such debonds in CSS. The study is further extended for the detection of debonds at different locations in the CSS, including a debond located at the edge to assess the potential of the proposed SHM approach.
Charge‐injection theory of bipolar junction transistors

A physical theory of the bipolar junction transistor which provides closed‐form solutions for current/voltage relations for generalized bias conditions is introduced. Included are the new concepts of emitter and collector collection efficiency. Both emitter and collector regions are treated symmetrically to allow for accurate treatment of operation in both the saturation region and the forward‐active region, as well as the reverse‐active region. There are six components each of emitter and collector current, resulting from inclusion of emitter injection efficiency, surface recombination at the pn junction peripheries, and bulk base recombination as well as finite minority‐carrier collection efficiency. Direct comparison between theory and experiment over the entire transistor operating range from deep saturation where IC=0 continuously into the forward‐active region where VCE is much greater than the thermal voltage VT shows excellent agreement.A physical theory of the bipolar junction transistor which provides closed‐form solutions for current/voltage relations for generalized bias conditions is introduced.

Visual Odometry and 3D Mapping in Indoor Environments

This paper presents a robust state estimation and 3D environment modeling approach that enables Micro Aerial Vehicle (MAV) operating in challenging GPS-denied indoor environments. A fast, accurate and robust approach to visual odometry is developed based on Microsoft Kinect. Discriminative features are extracted from RGB images and matched across consecutive frames. A robust least-square estimator is applied to get relative motion estimation. All computation is performed in real-time, which provides high frequency of 6 degree-of-freedom state estimation. A detailed 3D map of an indoor environment is also constructed.
