RFID tag antenna based temperature sensing using shape memory polymer actuation (2010)

Ubiquitous temperature monitoring is important to boost visibility in applications such as cold supply chain management. Current sensors monitor and log a time history of temperature data, but their cost limits the scale of deployment. In this paper, we propose an ultra-low cost temperature threshold sensor using the UHF RFID tag antenna as a sensing mechanism. Permanent changes are induced in the tag antenna electrical properties upon violation of a temperature threshold. This manifests itself in a change in backscatter power detected at the reader. We demonstrate how these changes are effected via shape memory polymer actuation. Experiments demonstrate that cheap, reliable temperature threshold sensors can be developed which are independent of the material of deployment, orientation of the sensor, which have a read range of over 3 m and which have a customizable critical temperature threshold.
Blood-borne collagenous debris complexes with plasma fibronectin after thermal injury (1990)

Plasma fibronectin augments the clearance of blood-borne foreign and effete complexes by mononuclear phagocytes. The release of a “gelatin- like” ligand into plasma after thermal injury has been reported. We quantified the release of this collagenous debris from thermally injured skin, and its potential interaction with soluble fibronectin in plasma using anesthetized rats. Collagen-like material debris in the plasma was detected by assay of hydroxyproline. Fibronectin was measured by a double antibody enzyme-linked immunosorbent assay (ELISA) technique. Over a 24-hour postburn interval, plasma hydroxyproline increased from 6.7 +/- 0.6 micrograms/mL to a maximum of 19.0 +/- 3.3 micrograms/mL at 60 minutes postburn, and normalized by 6 hours. A direct correlation existed between the magnitude of burn injury and the increase in plasma hydroxyproline. In parallel, plasma fibronectin declined over a 15-minute to 2-hour period postburn, and normalized by 3 to 4 hours with rebound hyperfibronectinemia observed at 24 hours. The elevation in total plasma hydroxyproline was not due to an increase in plasma Clq (zero time, 26.2 +/- 1.4 micrograms/mL; 60 minutes, 23.9 +/- 1.1 micrograms/mL). Tracer studies with 125I-fibronectin showed that the acute decline of plasma fibronectin was due to its uptake by the liver and binding to sites of tissue injury. Total hydroxyproline in extracts of burn skin, used as an index of soluble collagenous material, rose from 15 +/- 3.3 micrograms/g skin at zero time to 129.3 +/- 43.7 micrograms/g skin by 5 minutes postburn, with a decline to 38 +/- 22 micrograms/g skin by 24 hours. The formation of circulating fibronectin-gelatin complexes in vivo was documented by cross- immunoelectrophoresis coupled with autoradiography using 125I-gelatin as a model ligand. Thus, collagenous tissue debris from burned skin may enter the plasma after thermal injury and directly complexes with soluble fibronectin before hepatic phagocytic clearance.
(15 <i>R</i>)‐16‐<i>m</i>‐Tolyl‐17,18,19,20‐tetranorisocarbacyclin: A Stable Ligand with High Binding Affinity and Selectivity for a Prostacyclin Receptor in the Central Nervous System (1996)

Structural modification of the prostacyclin agonist isocarbacyclin resulted in the stable, highly selective ligand 1, which displays high binding affinity for a prostacyclin receptor in the central nervous system. The binding profile of 1 thus contrasts markedly with those of cicaprost and iloprost.
Human neutrophil phagocytic granules contain a truncated soluble form of the Alzheimer beta/A4 amyloid precursor protein (APP) (1994)

We have characterized the molecular species and subcellular distribution of Alzheimer beta/A4 amyloid precursor protein (APP) in neutrophilic granulocytes purified from human peripheral blood. APP was readily detectable in these cells. Immunochemical analysis with a panel of antibodies revealed that this APP species lacked the transmembrane and cytoplasmic domains previously demonstrated in cell-associated APP. However, it contained a protease inhibitor domain of the Kunitz type, indicating that neutrophil APP is a potent inhibitor of certain serine proteases. Upon subcellular fractionation, APP was primarily localized to azurophilic granules, which are neutrophil-specific phagocytic organelles assigned to enzymatic digestion of invading microbes and dead or injured tissue. Apparently, in the neutrophil, a nonsecretory organelle stores truncated, soluble APP, a species previously found only in blood plasma and cerebrospinal fluid or in conditioned medium of cultured cells. Soluble APP in neutrophils may therefore have intracellular functions in addition to its previously described extracellular functions. These findings also indicate that there are previously uncharacterized cell-specific differences in processing, trafficking, and storage of the APP molecule. Finally, the precise subcellular localization of APP to neutrophil-specific phagocytic organelles is suggestive of a role for APP in the nonimmunological host defense.
Subspace method optimized for tracking real-valued sinusoids in noise (2006)

Adaptive subspace-based frequency estimation of multiple real valued sine waves is considered in this paper. A novel combination of strong adaptive covariance matrix update and optimized block processing for frequency values retrieval is proposed. The new optimized approach combines the projection approximation subspace tracking technique (for the signal subspace update) with the ESPRIT-like frequency estimation of real-valued sinusoids (for frequency values retrieval). Consequently, a new adaptive subspace-tracking algorithm for frequency estimation is proposed. The algorithm is tested in numerical simulations and compared to complex-valued PAST method. The method proposed brings a significant reduction in arithmetical complexity at the same level of accuracy.

On the Boolean Algebra of Shape Analysis Constraints (2003)

Abstract. The parametric shape analysis framework of Sagiv, Reps, and Wilhelm [45,46] uses three-valued structures as dataflow lattice elements to represent sets of states at different program points. The recent work of Yorsh, Reps, Sagiv, Wilhelm [48,50] introduces a family of formulas in (classical, two-valued) logic that are isomorphic to three-valued structures [46] and represent the same sets of concrete states. In this paper we introduce a larger syntactic class of formulas that has the same expressive power as the formulas in [48]. The formulas in [48] can be viewed as a normal form of the formulas in our syntactic class; we give an algorithm for transforming our formulas to this normal form. Our formulas make it obvious that the constraints are closed under all boolean operations and therefore form a boolean algebra. Our algorithm also gives a reduction of the entailment and the equivalence problems for these constraints to the satisfiability problem.
Composition and Antinociceptive Activity of the Essential Oil from <i>Protium Heptaphyllum</i> Resin (2007)

The chemical composition of the essential oil from Protium heptaphyllum resin was analyzed by GC/MS and the oil examined for antinociceptive activity in chemical and thermal tests. Fourteen compounds were characterized, representing 95.8% of the total essential oil, with the monoterpenes α-phellandrene (10.4%), α-terpinene (13.7%) and 1,8-cineole (58.7%) as major components. Oral administration of the essential oil (50 and 100 mg/kg) significantly inhibited chemical nociception induced by capsaicin and formalin in mice. In rats, the oil also effectively enhanced the radiant heat-induced tail-flick latency response at a dose of 100 mg/kg. However, the essential oil, at either dose, was ineffective against thermal pain in the hot-plate test.
Object-Oriented State Machines (1993)

Ted Faison is a developer and writer, and has authored several articles and books on C++. He has been programming with the language since 1988, and holds a BSEE from California State University, Fullerton. Ted is president of Faison Computing, a firm which develops C++ class libraries for DOS and Windows. He can be reached at tedfaison@msn.com. Finite state machines have been in use in computer programming for many years. Systems that are primarily reactive in nature are often well described in terms of input events and outcomes. Such eventdriven systems can be expressed as a collection of states, each representing a mode in which the system has a specific set of behaviors or reactions to input events. States can react to events by switching the system to another state, by ignoring the event, or by generating other events. State machines represent a conceptually simple way to handle disparate programming tasks, and indeed find their way into many different kinds of programs- from grammar parsers to CD players. State machines often simplify software designs dramatically, because they mimic the way systems work conceptually, allowing difficult problems to be broken down into groups of simpler ones. The main tool in designing a state machine is the state transition diagram, or state diagram for short. A state diagram is a simply directed graph whose nodes represent states and whose arrows represent transitions from one state to another. The arrows are labeled with the name of the event that caused the transition. Some transitions might occur on conditionally, and in these cases, the condition is shown next to the event name, in parentheses. Figure 1 shows a simple state diagram. A
Photon Ranging for Upstream ONU Activation Signaling in TWDM-PON (2015)

This paper focuses on upstream signaling in TWDM-PON (one of the two systems specified in the new series of ITU-T G.989.x Recommendations for NG-PON2), for what concerns the discovery phase of a new ONU. The key idea is that a new ONU, that needs to be discovered by the OLT, would send a low bit rate signal that is set to a sufficiently low-power level to not affect significantly the upstream transmission performance of already active ONUs. We properly dimension the key physical layer parameters of this technique and demonstrate it experimentally. We named this proposal as “photon ranging” due to its ultralow-power transmission and we experimentally demonstrate its feasibility. As a “side effect” of this study, we had to deeply revise the power penalty generated by the optical interferometric crosstalk, the main impairment that impacts the proposed setup, obtaining new results that may be of interest also in areas not directly related to the specific framework of TWDM-PON.
Developments in thin-film photovoltaics for space (2002)

Thin-film solar cells are important for space because of their low cost, high power density, and radiation resistance. However, significant technological hurdles remain before thin-film technology may be implemented as the primary power source for spacecraft. A large-area fabrication process for high-efficiency (>10% AMO) cells on a lightweight substrate must still be demonstrated, and there are many issues associated with space qualification of both the photovoltaic material itself and the substrate which must be resolved. Also, new deployment, interconnection and control schemes must be developed. Ongoing efforts led and supported by the Air Force to overcome these obstacles are discussed.
Changes in Metabolic Chemical Reporter Structure Yield a Selective Probe of <i>O</i>-GlcNAc Modification (2014)

Metabolic chemical reporters (MCRs) of glycosylation are analogues of monosaccharides that contain bioorthogonal functionalities and enable the direct visualization and identification of glycoproteins from living cells. Each MCR was initially thought to report on specific types of glycosylation. We and others have demonstrated that several MCRs are metabolically transformed and enter multiple glycosylation pathways. Therefore, the development of selective MCRs remains a key unmet goal. We demonstrate here that 6-azido-6-deoxy-N-acetyl-glucosamine (6AzGlcNAc) is a specific MCR for O-GlcNAcylated proteins. Biochemical analysis and comparative proteomics with 6AzGlcNAc, N-azidoacetyl-glucosamine (GlcNAz), and N-azidoacetyl-galactosamine (GalNAz) revealed that 6AzGlcNAc exclusively labels intracellular proteins, while GlcNAz and GalNAz are incorporated into a combination of intracellular and extracellular/lumenal glycoproteins. Notably, 6AzGlcNAc cannot be biosynthetically transformed into the corresponding UDP sugar-donor by the canonical salvage-pathway that requires phosphorylation at the 6-hydroxyl. In vitro experiments showed that 6AzGlcNAc can bypass this roadblock through direct phosphorylation of its 1-hydroxyl by the enzyme phosphoacetylglucosamine mutase (AGM1). Taken together, 6AzGlcNAc enables the specific analysis of O-GlcNAcylated proteins, and these results suggest that specific MCRs for other types of glycosylation can be developed. Additionally, our data demonstrate that cells are equipped with a somewhat unappreciated metabolic flexibility with important implications for the biosynthesis of natural and unnatural carbohydrates.
Ten Guiding Principles for Designing Online Modules That Involve International Collaborations. (2014)

As ideas and personnel flow across borders, there are many opportunities for instructional designers to collaboratively design online modules with international teams. These collaborations can take many shapes, as varying levels of localization and within-team communication are employed. This paper looks at ten guiding principles that are shaping the work of an online module development project for training inservice teachers in Jordan. These principles can be effectively applied to a variety of cross-national collaborations for a wide range of settings.
Voltage-flux-characteristics of asymmetric dc SQUIDs (2001)

We present a detailed analysis of voltage-flux V(/spl Phi/)-characteristics for asymmetric dc SQUIDs with various kinds of asymmetries. For finite asymmetry /spl alpha//sub I/ in the critical currents of the two Josephson junctions, the minima in the V(/spl Phi/)-characteristics for bias currents of opposite polarity are shifted along the flux axis by /spl Delta//spl Phi/=/spl alpha//sub I//spl beta//sub L/ relative to each other; /spl beta//sub L/ is the screening parameter. This simple relation allows the determination of /spl alpha//sub I/ in our experiments on YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// dc SQUIDs and comparison with theory. Extensive numerical simulations within a wide range of /spl beta//sub L/ and noise parameter /spl Gamma/ reveal a systematic dependence of the transfer function V/sub /spl Phi// on /spl alpha//sub I/ and /spl alpha//sub R/ (junction resistance asymmetry). As for the symmetric dc SQUID, V/sub /spl Phi// factorizes into g(/spl Gamma//spl beta//sub L/)/spl middot/f(/spl alpha//sub I/,/spl beta//sub L/), where now f also depends on /spl alpha//sub I/. For /spl beta//sub L//spl lsim/5 we find mostly a decrease of V/sub /spl Phi// with increasing /spl alpha//sub I/, which however can only partially account for the frequently observed discrepancy in V/sub /spl Phi// between theory and experiment for high-T/sub c/ dc SQUIDs.
Absorbing boundary conditions for acoustic and elastic wave equations (1977)

abstract Boundary conditions are derived for numerical wave simulation that minimize artificial reflections from the edges of the domain of computation. In this way acoustic and elastic wave propagation in a limited area can be efficiently used to describe physical behavior in an unbounded domain. The boundary conditions are based on paraxial approximations of the scalar and elastic wave equations. They are computationally inexpensive and simple to apply, and they reduce reflections over a wide range of incident angles.
Examination of the Bonding in Binary Transition-Metal Monophosphides MP (M = Cr, Mn, Fe, Co) by X-Ray Photoelectron Spectroscopy (2005)

The binary transition-metal monophosphides CrP, MnP, FeP, and CoP have been studied with X-ray photoelectron spectroscopy. The shifts in phosphorus 2p(3/2) core line binding energies relative to that of elemental phosphorus indicated that the degree of ionicity of the metal-phosphorus bond decreases on progressing from CrP to CoP. The metal 2p(3/2) core line binding energies differ only slightly and show similar line shapes to those of the elemental metals, reaffirming the notion that these transition-metal phosphides have considerable metallic character. The satellite structure observed in the Co 2p(3/2) X-ray photoelectron spectra of Co metal and CoP was examined by reflection electron energy loss spectroscopy and has been attributed to plasmon loss, not final state effects as has been previously suggested. Valence-band spectra of the transition-metal phosphides agree well with the density of states profiles determined from band structure calculations. The electron populations of the different electronic states were extracted from the fitted valence-band spectra, and these confirm the presence of strong M-P and weak P-P bonding interactions. Atomic charges determined from the P 2p core line spectra and the fitted valence-band spectra support the approximate formulation M(1+)P(1-) for these phosphides.
IN SITU COMBUSTION IN ENHANCED OIL RECOVERY (EOR): A REVIEW (2007)

Enhanced oil recovery (EOR) refers to the technologies developed to increase extraction of crude oil from reservoirs after primary production. In situ combustion (ISC) is one of the methods developed for EOR. This review examines studies done by researchers worldwide to improve our understanding of the mechanism of oil cracking kinetics, which is one of the fundamental mechanisms of in situ combustion. Good agreement between the laboratory and field results has encouraged further research in this field. Extensive research at the laboratory scale to understand the pyrolysis and oxidation behavior of coke formed from medium and light oil and also to propose more realistic models to mimic the true behavior of in situ combustion has been undertaken in recent years. Apart from the classical Arrhenius model, researchers have come up with other models (two-step oxidation model) based on the type of combustion activity observed from their samples, thus modeling the process more accurately. Research work showing optimization of the parameters of ISC and improving the economic viability of the entire process is been one of the main focuses of this article. The review also explains the nature of the various experiments, sheds light on some of the concepts that remain unexplained, and opens the way for fresh thinking in those areas. It also highlights the possibility of developing global solutions for numerical simulation of this EOR process.

Kinetics and Mechanisms of Catalytic Oxygen Atom Transfer with Oxorhenium(V) Oxazoline Complexes (2001)

The rhenium(V) monooxo complexes (hoz)2Re(O)Cl (1) and [(hoz)2Re(O)(OH2)][OTf] (2) have been synthesized and fully characterized (hoz = 2-(2'-hydroxyphenyl)-2-oxazoline). A single-crystal X-ray structure of 2 has been solved: space group = P1, a = 13.61(2) A, b = 14.76(2) A, c = 11.871(14) A, alpha = 93.69(4) degrees, beta = 99.43(4) degrees, gamma = 108.44(4) degrees, Z = 4; the structure was refined to final residuals R = 0.0455 and Rw = 0.1055. 1 and 2 catalyze oxygen atom transfer from aryl sulfoxides to alkyl sulfides and oxygen-scrambling between sulfoxides to yield sulfone and sulfide. Superior catalytic activity has been observed for 2 due to the availability of a coordination site on the rhenium. The active form of the catalyst is a dioxo rhenium(VII) intermediate, [Re(O)2(hoz)2]+ (3). In the presence of sulfide, 3 is rapidly reduced to [Re(O)(hoz)2]+ with sulfoxide as the sole organic product. The transition state is very sensitive to electronic influences. A Hammett correlation plot with para-substituted thioanisole derivatives gave a reaction constant rho of -4.6 +/- 0.4, in agreement with an electrophilic oxygen transfer from rhenium. The catalytic reaction features inhibition by sulfides at high concentrations. The equilibrium constants for sulfide binding to complex 2 (cause of inhibition), K2 (L x mol(-1)), were determined for a few sulfides: Me2S (22 +/- 3), Et2S (14 +/- 2), and tBu2S (8 +/- 2). Thermodynamic data, obtained from equilibrium measurements in solution, show that the S=O bond in alkyl sulfoxides is stronger than in aryl sulfoxides. The Re=O bond strength in 3 was estimated to be about 20 kcal x mol(-1). The high activity and oxygen electrophilicity of complex 3 are discussed and related to analogous molybdenum systems.
Study on Thermal Environment and Questionnaire Investigation in Welfare Facilities (2007)

The purpose of this study is to clarify the influence of the thermal environment on the consciousness of elderly people in welfare facilities. In this paper, facilities where elderly people live actually were selected as research objects. The thermo-humidity environment was measured and the hearing surveys about thermal environment were carried out in summer.
Investigation of power oscillations along tapered monomode fibers (1987)

An abruptly tapered fiber can be essentially divided into three different regions: one beating region in its central, quasi-cylindrical part, lying between two coupling regions, where the slopes are large. In this paper we report two experiments which help to visualize and analyze the beating region. We show that, in this region, there are principally two modes present, HE(11) and HE(12), both excited with large amplitudes.
Reconfigurable memory controller with programmable pattern support (2011)

Heterogeneous architectures are increasingly popular due to their flexibility and high performance per watt capability. A kind of heterogeneous architecture, reconfigurable systems-on-chip, offer high performance per watt through the reconfigurable logic and flexibility via multiprocessor cores. But in order to achieve the performance goals it is necessary to provide enough data to the accelerators. In this paper we describe a programmable, pattern-based memory controller\n(PMC) that aims at improving the performance of heterogeneous or reconfigurable SoC devices. These include scatter gather and strided 1D, 2D and 3D patterns. PMC can prefetch complete patterns into scratchpads that can then be accessed either by a microprocessor or by an accelerator. As a result, the microprocessors and accelerators can focus on computation and are relieved of having to perform address calculations. PMC has been implemented and tested on an\nML505 evaluation board using the MicroBlaze softcore as the platform’s microprocessor.\nWhile PMC adds some latency, it improves performance by offloading the processor and by making better use of available bandwidths. The PMC provide 1.5x speed-ups with processor and 27x speed-ups achieved by using hardware accelerator in PMC SoC based environment while executing thresholding\napplication.
