Laboratory Studies on Membrane Deoiling of Lecithin (2008)

Abstract Deoiling of lecithin using a nonporous membrane was examined in a favorable solvent (hexane) medium with soy and rice bran lecithins. During the membrane process, the acetone insoluble (AI) content of soy lecithin increased from 63.2 to 81.0% in a single step batch operation. The membrane exhibited an excellent selectivity since phospholipid (PL) reverse micelles formed in the system were rejected almost completely due to low solubility probably aided synergistically by size exclusion. Diafiltration achieved greater oil removal from lecithin as reflected in terms of higher AI and PL contents in the deoiled lecithin. In discontinuous diafiltration, the PL content increased from 33.3 to 85.5% in rice bran lecithin (150% dilution to feed) and 56.6 to 85.7% in soy lecithin (200% dilution), respectively. The simulated continuous diafiltration run showed slightly greater PL content in soy lecithin (91.3%) compared to discontinuous diafiltration (89.7%) besides offering higher productivity. The membrane showed a color reduction of ~60% in soy lecithin but there was no improvement in rice bran lecithin due to the retention of degradation products. The proposed integrated membrane process with nonporous (deoiling) and nanofiltration (solvent recovery) membranes could be an attractive preposition besides being an acetone free process.
XMET—An Unattended Meteorological Sensing System for Austere Environments (2020)

Abstract Accurate surface meteorological (MET) observations reported reliably and in near–real time remain a critical component of on-scene environmental observation systems. Presented is a system developed by Scripps Institution of Oceanography that allows for rapid, global deployment of ground-based weather observations to support both timely decision-making and collection of high-quality weather time series for science or military applications in austere environments. Named the Expeditionary Meteorological (XMET), these weather stations have been deployed in extreme conditions devoid of infrastructure ranging from tropical, polar, maritime, and desert environments where near continuous observations were reported. To date, over 1 million weather observations have been collected during 225 deployments around the world with a data report success rate of 99.5%. XMET had its genesis during Operation Iraqi Freedom (OIF), when the U.S. Marine Corps 3rd Marine Aircraft Wing identified an immediate capability gap in environmental monitoring of their operation area due to high spatiotemporal variability of dust storms in the region. To address the sensing gap, XMET was developed to be a portable, expendable, ruggedized, self-contained, bidirectional, weather observation station that can be quickly deployed anywhere in the world to autonomously sample and report aviation weather observations. This paper provides an overview of the XMETs design, reliability in different environments, and examples of unique meteorological events that highlight both the unit’s reliability and ability to provide quality time series. The overview shows expeditionary MET sensing systems, such as the XMET, are able to provide long-term continuous observational records in remote and austere locations essential for regional spatiotemporal MET characterization.

A behavioral model of a class of mixed hardware-software systems is presented. A codesign methodology for such systems is defined. The methodology includes hardware-software partitioning, behavioral synthesis, software compilation, and demonstration on a testbed consisting of a commercial central processing unit (CPU), field-programmable gate arrays, and programmable interconnections. Design examples that illustrate how certain characteristics of system behavior and constraints suggest hardware or software implementation are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis of Narrowly Size-Distributed Thermosensitive Poly(<i>N</i>-isopropylacrylamide) Nanocapsules in Inverse Miniemulsion (2010)

Narrowly size-distributed thermosensitive poly(N-isopropylacrylamide) (PNIPAM) nanocapsules with a hydrophilic core composed of an aqueous solution of cobalt tetrafluoroborate (CoTFB) were synthesized via a one-pot polymerization of N-isopropylacrylamide (NIPAM) and the cross-linking agent N,N′-methylene bis(acrylamide) (MBA) in inverse miniemulsion. CoTFB not only worked as template and lipophobe, but also promoted the dissolution of NIPAM in water by the formation of a complex between NIPAM and CoTFB. The formation of PNIPAM nanocapsules was verified by transmission electron microscopy (TEM) and atomic force microscopy (AFM). This is the first report to synthesize nanocapsules in inverse miniemulsion by following a phase separation mechanism as proposed by Tiarks et al. in direct miniemulsion [Tiarks, F.; Landfester, K.; Antonietti, M. Langmuir 2001, 17, 908−918]. The particle size distribution was narrowed by increasing the weight content of CoTFB, MBA, and water. The particle size of the nanocapsules could be conveniently tuned by varying the weight content of CoTFB and MBA. The as-prepared PNIPAM nanocapsules showed reversible thermosensitive properties. An ordered monolayer of PNIPAM nanocapsules could form by controlling the evaporation of apolar solvent, and moreover the size and thus interparticle distance of PNIPAM nanocapsules in the ordered arrays could be tuned by drying the sample under different temperatures below and above the lower critical solution temperature (LCST) of PNIPAM.
Sonata: Query-Driven Network Telemetry (2017)

Operating networks depends on collecting and analyzing measurement data. Current technologies do not make it easy to do so, typically because they separate data collection (e.g., packet capture or flow monitoring) from analysis, producing either too much data to answer a general question or too little data to answer a detailed question. In this paper, we present Sonata, a network telemetry system that uses a uniform query interface to drive the joint collection and analysis of network traffic. Sonata takes the advantage of two emerging technologies---streaming analytics platforms and programmable network devices---to facilitate joint collection and analysis. Sonata allows operators to more directly express network traffic analysis tasks in terms of a high-level language. The underlying runtime partitions each query into a portion that runs on the switch and another that runs on the streaming analytics platform iteratively refines the query to efficiently capture only the traffic that pertains to the operator's query, and exploits sketches to reduce state in switches in exchange for more approximate results. Through an evaluation of a prototype implementation, we demonstrate that Sonata can support a wide range of network telemetry tasks with less state in the network, and lower data rates to streaming analytics systems, than current approaches can achieve.
The Conceptual Processing of a Natural Language Query System (1991)

This paper is intended to present an ANI (Applicable, Natural, and Intelligent) system process, based on the intelligent human-computer interaction of the natural language query system of a database. This system is base on a conceptual graph's formalism, which expresses the knowledge from pragmatic perception. A mechanism comprises a chain of reasoning and the characteristics of the user in the query system. In addition, the goal and the constraints of the queries and the adequate alternatives methodology are also illustrated in this paper. It is believed that this innovative and processing approach in comparison with conventional prestructured query system are more applicable, natural, and intelligent to manipulate the DBMS for retriveng a precise information from a database.
A new modulation scheme for multitransmitter simulcast digital mobile radio communication (1980)

Many mobile radio communication systems require digital signaling simultaneously from multiple transmitters from the viewpoints of efficient frequency utilization and simplified receiver construction. A new modulation scheme intended to realize simulcast digital transmission is described. In this method, a modulation signal is made by superimposing a specific wave on an ordinary rectangular digital wave. The two conditions necessary for obtaining a diversity effect equivalent to the maximal-ratio combining are mathematically derived. The specific waves for the various transmitters may be sinusoidal waves having a frequency equal to the original bit rate, and phases which differ from one transmitter to another. In order to clarify the feasibility of this technique, experimental simulation tests have been performed in the 900-MHz band in a two-transmitter configuration. It is proved that this modulation scheme, in comparison with the carrier-frequency offset strategy, not only gives the same amount of improvement in digital signaling in an overlapped area, but also makes the allowable carrier frequency drift more than ten times larger.

Neuronal apoptosis induced by chemical hypoxia is a process regulated by HIF-1α stabilization early on and by ER stress activation at later stages. Our data also suggested that HIF-1α levels were regulated by ER stress.

Ion-exchanged glass waveguides with low birefringence for a broad range of waveguide widths (2005)

Optical communications networks require integrated photonic components with negligible polarization dependence, which typically means that the waveguides must feature very low birefringence. Recent studies have shown that waveguides with low birefringence can be obtained, e.g., by use of silica-on-silicon waveguides or buried ion-exchanged glass waveguides. However, many integrated photonic circuits consist of waveguides with varying widths. Therefore low birefringence is consequently required for waveguides having different widths. This is a difficult task for most waveguide fabrication technologies. We present experimental results on waveguide birefringence for buried silver-sodium ion-exchanged glass waveguides. We show that the waveguide birefringence of the order of 10(-6) for waveguide mask opening widths ranging from 2 to 10 microm can be obtained by postprocessing the sample through annealing at an elevated temperature. The measured values are in agreement with the values calculated with our modeling software for ion-exchanged glass waveguides. This unique feature of ion-exchanged waveguides may be of significant importance in a wide variety of integrated photonic circuits requiring polarization-independent operation.

Doppler echocardiographic estimation of left ventricular end-diastolic pressure after MI in rats (2002)

The spectral Doppler mitral flow pattern, alone or combined with tissue Doppler mitral annulus velocity, can be used to predict left ventricular (LV) filling pressure in humans, whereas invasive hemodynamic measurements are still required in the rat. This study was undertaken to assess whether LV end-diastolic pressure (LVEDP) can be estimated using Doppler echocardiography in the rat after myocardial infarction (MI). Thirty-seven rats (23 rats with MI after left coronary artery ligation and 14 sham-operated rats) were evaluated 3 mo after surgery with echo-Doppler and invasive hemodynamic measurements. Pulse wave spectral Doppler at the mitral valve tip was used to measure the E wave, the E wave deceleration time (DT), and the A wave; spectral Doppler tissue imaging was used to measure the early diastolic lateral mitral annulus velocity (E(a)). We found weak correlations between LVEDP and the peak velocity of the early mitral inflow (E), E/peak velocity of the late mitral inflow, and DT, and strong correlations with E(a) and especially with E/E(a) [R(2) = 0.89, LVEDP (in mmHg) = 0.987E/E(a) - 4.229]. Longitudinal followup of a subgroup of rats with MI revealed a marked rise of E/E(a) between days 7 and 21 in rats with heart failure only. We conclude that Doppler echocardiography can be used for serial assessment of LV diastolic function in rats with MI.
Scale equalization higher-order neural networks (2005)

This paper presents a novel approach, called scale equalization (SE), to implement higher-order neural networks. SE is particularly useful in eliminating the scale divergence problem commonly encountered in higher order networks. Generally, the larger the scale divergence is, the more the number of training steps required to complete the training process. Effectiveness of SE is illustrated with an exemplar higher-order network built on the Sigma-Pi network (SESPN) applied to function approximation. SESPN requires the same computation time as SPN per epoch, but it takes much less number of epochs to compete the training process. Empirical results are provided to verify that SESPN outperforms other higher-order neural networks in terms of computation efficiency.
Some Properties of LaNi5-xAlx Metal Alloys and the Diffusion Coefficient and Solubility of Hydrogen in Cyclohexane (1994)

Pressure-composition isotherms for hydrogen absorption and desorption have been measured for several alloys of the LaNi5-xAlx family at 298, 308, 323, 333, and 348 K, and the ΔHº and ΔSº of the hydride formation reaction were obtained. The equilibrium pressure is strongly related to the aluminum content in the alloy. Other specific properties which have been determined are the density of the metal alloys and the particle size distribution and surface area of the material after about 50 absorption/desorption cycles with pure hydrogen. Additionally, the solubility and the diffusion coefficient of hydrogen in cyclohexane have been measured, and the solubility of hydrogen in ethanol has been correlated with results available in the literature.
Recognition and Management of Inferior Wall Myocardial Infarctions and Right Ventricular Infarcts (2001)

Cardiovascular disease is a predominant health problem in the United States. Annually, more than 6 million people experience an acute myocardial infarction (MI). Right ventricular infarct (RVI) occurs in approximately one third of all patients who present with an inferior wall myocardial infarction (IWMI). The aggressive initial treatment of IWMI with RVI may improve morbidity and mortality. Thus, it is essential to understand the different modalities used to treat a right and left ventricular MI.
Heteronuclear Micro-Helmholtz Coil Facilitates µm-Range Spatial and Sub-Hz Spectral Resolution NMR of nL-Volume Samples on Customisable Microfluidic Chips (2016)

We present a completely revised generation of a modular micro-NMR detector, featuring an active sample volume of ∼ 100 nL, and an improvement of 87% in probe efficiency. The detector is capable of rapidly screening different samples using exchangeable, application-specific, MEMS-fabricated, microfluidic sample containers. In contrast to our previous design, the sample holder chips can be simply sealed with adhesive tape, with excellent adhesion due to the smooth surfaces surrounding the fluidic ports, and so withstand pressures of ∼2.5 bar, while simultaneously enabling high spectral resolution up to 0.62 Hz for H2O, due to its optimised geometry. We have additionally reworked the coil design and fabrication processes, replacing liquid photoresists by dry film stock, whose final thickness does not depend on accurate volume dispensing or precise levelling during curing. We further introduced mechanical alignment structures to avoid time-intensive optical alignment of the chip stacks during assembly, while we exchanged the laser-cut, PMMA spacers by diced glass spacers, which are not susceptible to melting during cutting. Doing so led to an overall simplification of the entire fabrication chain, while simultaneously increasing the yield, due to an improved uniformity of thickness of the individual layers, and in addition, due to more accurate vertical positioning of the wirebonded coils, now delimited by a post base plateau. We demonstrate the capability of the design by acquiring a 1H spectrum of ∼ 11 nmol sucrose dissolved in D2O, where we achieved a linewidth of 1.25 Hz for the TSP reference peak. Chemical shift imaging experiments were further recorded from voxel volumes of only ∼ 1.5 nL, which corresponded to amounts of just 1.5 nmol per voxel for a 1 M concentration. To extend the micro-detector to other nuclei of interest, we have implemented a trap circuit, enabling heteronuclear spectroscopy, demonstrated by two 1H/13C 2D HSQC experiments.
Preference-Based Rank Elicitation using Statistical Models: The Case of Mallows (2014)

We address the problem of rank elicitation assuming that the underlying data generating process is characterized by a probability distribution on the set of all rankings (total orders) of a given set of items. Instead of asking for complete rankings, however, our learner is only allowed to query pairwise preferences. Using information of that kind, the goal of the learner is to reliably predict properties of the distribution, such as the most probable top-item, the most probable ranking, or the distribution itself. More specifically, learning is done in an online manner, and the goal is to minimize sample complexity while guaranteeing a certain level of confidence.
Optimal Search on a Technology Landscape (1998)

Technological change at the #rm-level has commonly been modeled as random sampling from a #xed distribution of possibilities. Such models, however, typically ignore empirically important aspects of the #rm&apos;s search process,notably the observation that the present state of the #rm guides future innovation. In this paper we explicitly treat this aspect of the #rm&apos;s search for technological improvements by introducing a #technology landscape&quot; into an otherwise standard dynamic programming setting where the optimal strategy is to assign a reservation price to each possible technology. Search is modeled as movement,constrained by the cost of innovation, over the technology landscape. Simulations are presented on a stylized technology landscape while analytic results are derived using landscapes that are similar to Markov random #elds. We #nd that early in the search for technological improvements,if the initial position is poor or average,it is optimal to search far away on the technology l...

Wireless energy transmission for structural health monitoring embedded sensor nodes (2007)

In this paper, we present a feasibility study of using wireless energy transmission systems to provide a required power for structural health monitoring (SHM) sensor nodes. The goal of this study is to develop SHM sensing systems which can be permanently embedded in the host structure and do not require an on-board power sources. With this approach, the energy will be periodically delivered as needed to operate the sensor node, as opposed to being harvested as in the conventional approaches. The wirelessly transmitted microwave energy is captured by a microstrip patch antenna, and then transformed into DC power by a rectifying circuit and stored in a storage medium to provide the required energy to the sensor and transmitter. Based on the fact that recent networked sensor systems require power on the order of fractions of a watt, it is quite possible to operate such sensing devices completely from the captured wirelessly delivered energy. The method of designing and optimizing a wireless energy transmission system is discussed. This paper also summarizes considerations needed to design such energy delivery systems, experimental procedures and results, and additional issues that can be used as guidelines for future investigations.
Tamper resistance evaluation of PUF in environmental variations (2016)

The damage caused by counterfeits of semiconductors has become a serious problem. Recently, a physical unclonable function (PUF) has attracted attention as a technique to prevent counterfeiting. The present study investigates an arbiter PUF, which is a typical PUF. The vulnerability of a PUF against machine-learning attacks has been revealed. It has also been indicated that the output of a PUF is inverted from its normal output owing to the difference in environmental variations, such as the changes in power supply voltage and temperature. The resistance of a PUF against machine-learning attacks due to the difference in environmental variation has seldom been evaluated. The present study evaluated the resistance of an arbiter PUF against machine-learning attacks due to the difference in environmental variation. By performing an evaluation experiment using a simulation, the present study revealed that the resistance of an arbiter PUF against machine-learning attacks due to environmental variation was slightly improved. However, the present study also successfully predicted more than 95% of the outputs by increasing the number of learning cycles. Therefore, an arbiter PUF was revealed to be vulnerable to machine-learning attacks even after environmental variation.
Isolation and characterization of naphthalene biodegrading Methylobacterium radiotolerans bacterium from the eastern coastline of the Kingdom of Saudi Arabia (2016)

Abstract Bioremediation is based on microorganisms able to use pollutants either as a source of carbon or in co-metabolism, and is a promising strategy in cleaning the environment. Using soil contaminated with petroleum products from an industrial area in Saudi Arabia (Jubail), and after enrichment with the polycyclic aromatic hydrocarbon (PAH) naphthalene, a Methylobacterium radiotolerans strain (N7A0) was isolated that can grow in the presence of naphthalene as the sole source of carbon. M. radiotolerans is known to be resistant to gamma radiation, and this is the first documented report of a strain of this bacterium using a PAH as the sole source of carbon. The commonly reported Pseudomonas aeruginosa (strain N7B1) that biodegrades naphthalene was also identified, and gas chromatography analyses have shown that the biodegradation of naphthalene by M. radiotolerans and P. aeruginosa did follow both the salicylate and phthalate pathways.
