Thermionic Fuel Element Test Rig: Testing of Single Cell Thermionic Fuel Element Technology (1994)

The Thermionic Fuel Element Test Rig is designed for non‐nuclear testing of individual single cell thermionic fuel elements utilizing electric heaters as a part of the Thermionic System Evaluation Test (TSET) Facility, at the New Mexico Engineering Research Institute (NMERI), in Albuquerque, New Mexico. The test rig was purchased from the Republic of Russia and assembled jointly by Russian and American specialists from JV Inertek, a Russian Corporation and the New Mexico Strategic Alliance (Air Force Phillips Laboratory, Sandia National Laboratory, Los Alamos National Laboratory, and the University of New Mexico). Initial certification testing and system qualifications testing were completed in December 1992. In the fall of 1993, US personnel completed certification as operators of the test rig and conducted additional testing to verify previous results. The testing is being funded by the Ballistic Missile Defense Organization (BMDO) and is being executed by the Air Force Phillips Laboratory.
Early gold weight eyelid implantation for facial paralysis (1990)

Facial paralysis can result in serious keratopathy because of corneal exposure and inadequate lacrimation. Thirty-seven patients underwent thirty-eight gold weight upper lid implants to rehabilitate paralysis of the eyelid from various causes. When indicated, implantation was combined with lower lid ectropion repair, medial canthoplasty or brow lift. Because of encouraging results in patients with longstanding facial paralysis, "early" implantation (within 1 month of paralysis) was offered to patients with severe lagophthalmos in whom (1) a severe neural injury was documented at the time of transtemporal surgery or (2) delayed, incomplete return of function was expected. Gold weight implantation resulted in excellent eyelid closure, protection, and cosmesis. There were no infections or extrusions. Lagophthalmos and exposure keratitis resolved or were significantly improved in all patients, and most were able to dispense with eyedrops and salves. Visual acuity improved in 95% of patients--a benefit even those without preoperative keratitis often achieved. A mild worsening of one patient's pre-existing astigmatism developed, which resolved after reimplantation with a lighter weight. The implant is easily removed from those patients who, having undergone early implantation, eventually recover adequate function. Gold weight loading has become our procedure of choice for eyelid rehabilitation.

Fixed Points of a Coupled Order System in 1/n Expansion (1977)

A critical behavior of a coupled order system in φ4-theory is investigated. Two fields φ1 and φ2 have components, and their numbers are given by n and m, respectively. The interaction of two fields is represented as g2 φ12 φ22. The fixed points and the critical exponent η are studied in the large n and large m limit. The relation of a present model to an anisotropic n-vector model is also discussed.
Temperature threshold in the screening of bacterial infections in young infants with hypothermia (2022)

Young infants with SBI and IBI presented with lower temperatures than infants without infections. However, there was no temperature threshold to reliably identify SBI or IBI. Further research incorporating clinical and laboratory parameters, in addition to temperature, may help to improve risk stratification for these vulnerable patients.

Polypeptide linkages and resulting structural features as powerful chromogenic factors in the Lowry phenol reaction. Studies on a glycoprotein containing no Lowry phenol-reactive amino acids and on its desialylated and deglycosylated products (1978)

With bovine serum albumin as the reference standard, the armadillo salivary-gland glycoprotein, although containing no chromogenic amino acids and only small amounts of colour-yielding peptides [Chou & Goldstein (1960) Biochem. J. 75, 100-115], is highly reactive in the Lowry phenol protein assay [Wu & Pigman (1977) Biochem. J. 161, 37-47]. After desialylation and Smith degradation of the glycoprotein, the Lowry phenol value increased by 13 and 30% respectively, which suggests that both sialic acid and N-acetylhexosamine exert shielding effects in this reaction. Acid hydrolysis for 30 min decreased the Lowry phenol value by more than 45%, which indicates that the peptide linkages and steric features affect the Lowry phenol reactivity. After hydrolysis for up to 6h, the remaining Lowry phenol value of the partially hydrolysed core protein paralleled the amount of unhydrolysed peptides, inferring that both acid-sensitive and acid-resistant chromophoric peptides are fairly evenly distributed along the whole polypeptide chain. As with bovine serum albumin, more than 80% of the colour yield obtained in the Lowry phenol assay with this glycoprotein is Cu2+-dependent.
Membrane Technology (2017)

Abstract Membrane separation is based on selective transport through the membrane. Increasingly, membrane technology has developed and is currently being used in a broad range of industrial applications. This article provides an overview of the fundamentals of membrane technology, the fabrication of various membranes, and the use of membranes in scaled‐up modules of various geometries for industrial applications. Different membrane processes are introduced: (i) microfiltration and ultrafiltration; (ii) nanofiltration and reverse osmosis (extended to forward osmosis); (iii) pervaporation, as stand‐alone processes or in hybrid configuration and in membrane reactors; (iv) dialysis, particularly for medical use; (v) electrodialysis and derived processes using selective or bipolar membranes; (vi) gas permeation for hydrogen and carbon dioxide separation. The use of membranes in energy‐related applications includes the development of pressure‐retarded osmosis, reverse electrodialysis, fuel cells, and microbial fuel cells. The emerging use of membrane contactors (membrane distillation, membrane absorption) is described as a combination of a classical separation, enhanced with membranes to improve drastically the mass transfer.
Civionics — A New Paradigm in Design, Evaluation, and Risk Analysis of Civil Structures (2007)

This article discusses the reasons why civil engineers are very conservative in the design of new structures and the evaluation of existing structures. It is argued that structural health monitoring (SHM) will assist in providing data that could be used to fine-tune the calibration of load and strength factors leading to more efficient and economical designs and better utilization of the strengths of existing structures. For major changes in design, construction, and evaluation to be accepted, it is necessary that innovative structures be monitored for their health so that the required data bank can be developed. To assist in achieving this goal, civil engineers in Canada are developing a new discipline, which integrates civil engineering and electrophotonics under the combined term `civionics'.
Fully integrated micromachined inductors with electroplated anisotropic magnetic cores (2002)

Batch fabricated, integrated magnetic devices incorporating magnetically anisotropic cores are investigated. These devices are realized using low temperature processes and electroplating techniques. Three different geometries of inductors, each possessing two core materials, permalloy (NiFe) and supermalloy (NiFeMo), are presented. The cores have been rendered magnetically anisotropic by application of a magnetic field during electrodeposition, resulting in an easy and hard axis orientation. In addition, some cores consist of a two-layer electrodeposit separated by a polyimide film lamination. At low frequencies (less than 100 kHz), the easy axis devices have higher inductances than the hard axis devices. However, the hard axis devices have better performance at higher frequency due to a far less steep falloff of material permeability as a function of frequency in the hard direction.

An observation of the Galactic center hard X-ray source, 1E 1740.7-2942, with the Caltech coded-aperture telescope (1993)

The Galactic center region hard X-ray source 1E 1740.7-2942 has been observed with the Caltech Gamma-Ray Imaging Payload (GRIP) from Alice Springs, Australia, on 1988 April 12 and on 1989 April 3 and 4. We report here results from the 1989 measurements based on 14 hr of observation of the Galactic center region. The observations showed 1E 1740.7-2942 to be in its normal state, having a spectrum between 35 and 200 keV characterized by a power law with an exponent of -2.2 +/- 0.3 and flux at 100 keV of (7.0 +/- 0.7) x 10 exp -5 sq cm s keV. No flux was detected above 200 keV. A search for time variability in the spectrum of 1E 1740.7-2942 on one hour time scales showed no evidence for variability.
A CD‐Spectroscopic Alternative to Methylation Analysis of Oligosaccharides: Reference Spectra for Identification of Chromophoric Glycopyranoside Derivatives (1990)

Abstract A microscale method for identifying the monosaccharide units and their linkages in oligosaccharides is presented. Sugar components are identified by UV and CD spectroscopy of chromophoric degradation products. CD spectral data for approximately 150 different glycopyranoside components are provided for use as reference spectra in the identification of unknown derivatives. Procedures for the conversion of oligosaccharides to monosaccharide subunits bearing 4‐bromobenzoate and 4‐methoxycinnamate chromophores have been developed based on acetolysis/bromination reactions for glycosidic cleavage of per (bromobenzoylated) oligosaccharides. The method offers an alternative means to conventional methylation analysis of oligosaccharides.
High performance low-bandgap (0.8 eV) single junction GaInNAsSb solar cells incorporating Au-based back surface reflectors (2021)

Low-bandgap GaInNAsSb single junction solar cells incorporating a planar Au back surface reflector for enhancing the photocurrent generation are reported. In particular, a 700 nm thick GaInNAsSb junction with a bandgap of 0.78 eV (corresponding to 6.2% N) incorporating the back reflector exhibited a short-circuit current density of 15.2 mA/cm2 for AM1.5D (1000 W/m2) illumination, when placed underneath a GaAs-filter mimicking the operation of a multijunction architecture. The corresponding external quantum efficiency represents the highest external quantum efficiency reported so far for dilute nitride solar cells with bandgaps below 0.8 eV. Electrical simulations reveal that the relatively high value of the quantum efficiency is attributed to a low p-type carrier concentration and partially to the varying doping level in the GaInNAsSb region. Moreover, the absorption coefficients for low-bandgap GaInNAsSb materials are estimated and used in a comprehensive optical analysis to understand the photon harvesting performance of the solar cells with reflector. The analysis reveals incomplete absorption in the GaInNAsSb layers for the double-pass configuration enabled by the planar back reflector pointing to the need for deploying more advanced structured reflectors. However, the structures exhibited high collection efficiencies laying the foundation for further improvements of the quantum efficiency values. Moreover, the low-bandgap dilute nitride solar cells show potential to meet the current-matching requirements in next-generation multijunction devices with five or more junctions, thus being a prospective alternative for replacing Ge as the bottom junction.

Genetic algorithm design of complexity-controlled time-series predictors (2003)

A genetic algorithm that designs artificial neural networks for time-series prediction encodes the structure and the weight magnitudes in a novel genome representation. This allows the genetic algorithm to perform training and complexity control simultaneously, thus directly addressing the problems of generalization and overfitting of data in the evolution of the network. Modified genetic crossover and modified mutation operations are introduced to increase population diversity and improve speed of convergence. Well performing neural networks were evolved automatically for time-series prediction of atmospherically-perturbed light waves in adaptive optics and the time series used in the 1998 Leuven predictor competition.
The Politics of the Soul (2022)

This book takes the form of intellectual histories of eight major representative figures of the twentieth century, who inherited and responded to the spiritual problematic left by Nietzsche. With each figure offering very different ethical and spiritual positions, all shed light on what we mean when we talk confusedly around the topics of politics and religion. With portraits of Max Weber, Georg Lukács, T.S. Eliot, W.H. Auden, Sigmund Freud, Carl Jung, George Orwell and Hannah Arendt, the author explores the "latent" content of their worldview—the moral (or immoral) intention of their intellectual project. In each of the case studies, the aim is to move toward an understanding of their ultimate values, to get at their particular picture of the soul, as well as the implications of this vision for religion and politics. As such, The Politics of the Soul will appeal to scholars of sociology and social theory, religion, philosophy, political theory and cultural studies.
Surface states and persistent photocurrent in a GaN heterostructure field effect transistor (2006)

AlGaN/GaN heterostructure field effect transistors subject to UV illumination exhibit persistent photoconductivity both in the gate leakage and in the drain current. Time decay modelling of the gate photocurrent enables us to extract the surface potential transient. Simultaneous measurements of drain and gate currents indicate that (i) the gate leakage current negatively charges surface states, (ii) the large change in surface potential induced by UV illumination is responsible for the change in drain current in these devices. We present a detailed analytical model describing the gate and drain current decay transients, following UV illumination, in terms of surface potential modulation due to charging and discharging of surface traps. It is also found that for constant illumination and drain bias voltage conditions the change in the two-dimensional electron gas density is nearly constant independent of the gate bias. Using a previously measured mobility–carrier density relation we determine quantitatively the drain current transient.

Perpetual Motion Machine (2008)

Ever since the first century A.D. there have been relative descriptions of known devices as well as manufactures for the creation of perpetual motion machines. Although physics has led, with two thermodynamic laws, to the opinion that a perpetual motion machine is impossible to be manufactured, inventors of every age and educational level appear to claim that they have invented something entirely new or they have improved somebody else's invention, which will function henceforth perpetually! However the fact of the failure in manufacturing a perpetual motion machine till now, it does not mean that countless historical elements for these fictional machines become indifferent. The discussion on every version of a perpetual motion machine on the one hand gives the chance to comprehend the inventor's of each period level of knowledge and his way of thinking, and on the other hand, to locate the points where this perpetual motion machine clashes with the laws of nature and that's why it is impossible to have been manufactured or have functioned. The presentation of a new perpetual motion machine has excited our interest to locate its weak points. According to the designer of it the machine functions with the work produced by the buoyant force
Esterification of ethylenediaminetetraacetic acid (1972)

Abstract The esterification of ethylenediaminetetraacetic acid (EDTA) in a hot acidic medium gives rise to impure products. The impurities have been identified and shown to be esters of various acids: nitrilotriacetic acid; iminodiacetic acid; piperazine‐1,4‐diacetic acid; N‐methylethylenediaminetriacetic acid; N,N‐ and N,N′ ‐dimethylethylenediaminediacetic acids and 2‐ketopiperazine‐1,4‐diacetic acid. The reactions for the formation of these impurities are discussed and a method for the preparation of pure esters of EDTA is described. Details of some crystalline derivatives, 1 H‐n.m.r. and infrared spectra of a series of esters of EDTA are presented. The determination of the molecular weights of the esters by saponification is discussed.
Effects of hypoxia on granulocytic‐monocytic progenitors in rats. Role of bone marrow stroma (2000)

Hemorrhagic shock leads to hypoxia and is associated with bone marrow (BM) failure. Hemorrhagic shock is also a predisposing factor in immune dysregulation. Since the BM is the major organ of immune cells in the adult, its failure following hemorrhagic shock may explain the increased susceptibility to infection. The in vitro evidence indicates that hypoxia mediates altered functions in BM stroma. Since similar hematopoietic alterations are reported in hypoxia and hemorrhagic shock, hypoxia alone could be a representative model to study BM responses during hemorrhagic shock. In this study, we use an animal model to dissect the hematopoietic effects of hypoxia. We subjected rats to hypoxia, and at days 1 and 5 post-hypoxia we determined the numbers of granulocytic–monocytic progenitors (CFU-GM) in the BM. We found significant increase (P < 0.05) in CFU-GM at day 1 and a downward trend by day 5. Enhanced BM cellularity could not explain the increase in CFU-GM by day 1. BM stromal cells mediated most of the stimulatory effects by hypoxia. CFU-GM was inversely proportional to bioactive TGF-β and directly proportional to IL-1. Compared to normoxic rats, IL-6 production was suppressed in BM cells from hypoxic rats. The results show that hypoxia alone initiate a stimulatory response in CFU-GM progenitors. These effects are at least partially mediated through the BM stroma. In the absence of a second insult, CFU-GM reverts to baseline. The data also suggest that hypoxia mediates complex responses that include cytokine production. These results add to the current understanding of hematopoietic responses by hypoxia and adds to the mechanisms of immune dysfunctions following hemorrhagic shock. Am. J.

Topical administration of the mithocondrial PTP opening inhibitor CoQ10 prevents apoptotic cell death induced by UVC-irradiation in rat's corneas and rabbit's retinas. (2008)

We have previously demonstrated in vitro that ubiquitous free radical scavenger coenzyme Q10 prevents keratocyte apoptosis induced by excimer laser irradiation more efficiently than other antioxidants. We showed that its anti apoptotic property is independent of its free radical scavenging ability and is related to direct inhibition of PTP (permeability transition pore) opening and mitochondrial depolarization. Here, we demonstrate in vivo, that CoQ10 can efficiently protect rat's corneas and rabbit's retinas irradiated with UVC. Therefore, we propose application of CoQ10 as countermeasure to prevent micro radiation-induced eye damage during interplanetary space exploration.
Iontophoretic Application of Adenine Arabinoside Monophosphate to Herpes Simplex Virus Type 1-Infected Hairless Mouse Skin (1978)

Several antiviral agents were applied topically or by iontophoresis to hairless mouse skin inoculated with herpes simplex virus type 1 (HSV-1), and the chemotherapeutic effectiveness was evaluated. Topical application of iododeoxyuridine, arabinoside A, and adenine arabinoside monophosphate (ara-AMP) moderately decreased the average lesion score, number of mice with paralysis, and number of mice dying in HSV-1-infected animals. Also, the mean survival time was moderately prolonged by topical application of those antiviral agents. When ara-AMP was applied by cathodal (-) iontophoresis to the HSV-1-infected skin, the average lesion score, number of mice with paralysis, and number of mice dying were greatly decreased. Furthermore, the mean survival time of mice was highly increased by cathodal (-) iontophoresis of ara-AMP. The therapeutic efficacy of ara-AMP iontophoresis was much superior to the topical application of iododeoxyuridine, arabinoside A, and ara-AMP. These data suggest that ara-AMP iontophoresis would be the method of choice for the management of HSV-1 skin lesions in hairless mice.
A Novel Wideband Spectrum Sensing System for Distributed Cognitive Radio Networks (2011)

A significant challenge of cognitive radio (CR) is to perform wideband spectrum sensing in a fading environment. In this paper, a novel multi-rate sub-Nyquist spectrum detection(MSSD) system is introduced for cooperative wideband spectrum sensing in a distributed CR network. Using only a few sub- Nyquist samples, MSSD is able to sense the wideband spectrum without full spectrum recovery. Specifically, given the low spectral occupancy, sub-Nyquist sampling is performed in each sampling channel and a test statistic is formed by using sub-Nyquist samples from multiple sampling channels. Furthermore, the use of different sub-Nyquist sampling rates is proposed to improve the system detection performance, and the performance of MSSD over both non-fading and Rayleigh fading channels is analyzed. Numerical results show that MSSD can considerably improve the wideband spectrum sensing performance in a fading scenario, with a relatively low implementation complexity and a low computational complexity.
