An Examination of Land Use Models, Emphasizing UrbanSim, TELUM, and Suitability Analysis (2008)

This work provides integrated transportation land use modeling guidance to practitioners in Texas regions of all sizes. The research team synthesized existing land use modeling experiences from metropolitan planning organizations (MPOs) across the country, examined the compatibility of TELUM’s and UrbanSim’s requirements with existing data sets, integrated both UrbanSim and a gravity-based land use modeling with an existing travel demand model (TDM), and examined the results of Waco and Austin land use model runs (with and without transportation and land use policies in place). A simpler, geographic information system (GIS)-based land use suitability analysis was also performed, for Waco, to demonstrate the potential value of such approaches. Finally, the knowledge gained from this research project was disseminated to practicing planners through a Resource Manual/Guidebook and two workshops.
Parallel discrete event simulation (1989)

This tutorial surveys the state of the art in executing discrete event simulation programs on a parallel computer. Specifically, we will focus attention on asynchronous simulation programs where few events occur at any single point in simulated time, necessitating the concurrent execution of events occurring at different points in time.We first describe the parallel discrete event simulation problem, and examine why it so difficult. We review several simulation strategies that have been proposed, and discuss the underlying ideas on which they are based. We critique existing approaches in order to clarify their respective strengths and weaknesses.
Recent advances in the determination of enantiomeric drugs and their metabolites in biological fluids by capillary electrophoresis‐mediated microanalysis (2003)

This review summarizes the recent developments in the application of electromigration techniques for the enantioselective analysis of drugs and metabolites in biological fluids. During the period covered by this review, it has been observed an increase in the use of negatively charged chiral selectors, particularly sulfobutyl ether-beta-cyclodextrin and sulfated-beta-cyclodextrin, and the combination of two different chiral selectors in the running buffer to obtain the resolution of drugs and their metabolites. Low detection limits as required for pharmacokinetic studies were obtained by using concentration techniques, including sample stacking procedures, and more sensitive detection systems, such as laser-induced fluorescence and mass spectrometry. Finally, the major points are discussed that can be considered to obtain reliable methods for enantioselective bioanalysis.
Antibodies to watch in 2016 (2015)

The number of novel antibody therapeutics that received first marketing approvals in 2015 met expectations, with 6 (alirocumab (Praluent®), evolocumab (Repatha®), daratumumab (Darzalex®), dinutuximab (Unituxin®), idarucizumab (Praxbind®), mepolizumab (Nucala®)) granted first approvals as of mid-November*. Seven novel antibody therapeutics (begelomab, brodalumab, elotuzumab, ixekizumab, necitumumab, obiltoxaximab, reslizumab) are in regulatory review, and thus a similar number, if not more, are projected to gain first approvals in 2016. Commercial late-stage antibody therapeutics development exceeded expectations by increasing from 39 candidates in Phase 3 studies as of late 2014 to 53 as of late 2015. Of the 53 candidates, transitions to regulatory review by the end of 2016 are projected for 8 (atezolizumab, benralizumab, bimagrumab, durvalumab, inotuzumab ozogamicin, lebrikizumab, ocrelizumab, tremelimumab). Other "antibodies to watch" include 15 candidates (bavituximab, bococizumab, dupilumab, fasinumab, fulranumab, gevokizumab, guselkumab, ibalizumab, LY2951742, onartuzumab, REGN2222, roledumab, romosozumab, sirukumab, Xilonix) undergoing evaluation in Phase 3 studies that have estimated primary completion dates in 2016. As evidenced by the antibody therapeutics discussed in this perspective, the biopharmaceutical industry has a highly active late-stage clinical pipeline that may deliver numerous new products to the global market in the near future. *See Note added in proof for updates through December 31, 2015.
Power Scaling of Cr2+:ZnSe Lasers (2001)

We describe continuous-wave, quasi-continuous-wave and gain-switched operation of moderate power Cr:ZnSe lasers. We have demonstrated CW output powers as high as 1.83 W, quasi-CW power of 3.6 W at 10% duty cycle, and 0.35 mJ gain- switched pulses at a repetition frequency of 1000 Hz.
Some New Methods of Precision X-Ray Spectrometry (1972)

Abstract Three novel methods of x-ray spectrometry have been developed in recent years at Texas Tech University. These are: 1. Three crystal spectrometer 2. Two curved crystal spectrometer 3. Spherically bent crystal spectrometer. In this paper the new design features, and experimental results will be discussed to indicate the usefulness of the new instruments. The three crystal spectrometer is a modified two crystal instrument. A third crystal is used to analyze the output of the two crystal spectrometer. The first two crystals are operated as a standard two crystal spectrometer. The third crystal is swept through the spectrum transmitted by the first two crystals for each setting of the first two crystals. The peak intensity of the third crystal sweep corresponds to the energy setting of the two crystal spectrometer, and is the intensity used to plot the spectral lines. The two curved crystal spectrometer utilizes two transmission spectrographs with radii having a 2:1 ratio in series, the crystal with the smaller radius being set so that its focal point falls on the Rowland circle of the larger radius crystal, This instrument has a very low background intensity and is suitable for precision scattering and diffraetion work. The spherically bent crystal spectrometer makes use of high light gathering power and high orders of reflection to allow high resolution studies of weak spectral lines. It also has the advantage of ease of alignment and operation.
The development of the alum‐amine process for the recovery of alumina from shale (1960)

Abstract Based on a review of the extensive published literature on the recovery of alumina from clays and shale, sufficient experimental work was done on a bench scale to establish a flow sheet whereby these materials might be treated for the recovery of cell‐grade alumina. The significant step in the processing is the recovery of potassium alum, and its purification by either recrystallization or liquid‐liquid extraction.

Glycosaminoglycans and Proteoglycans: Overlooked Entities? (2007)

Recent advances in the field of glycobiology have revealed a multitude of biologic processes that are controlled or influenced by glycosaminoglycans and proteoglycans. Altered synthesis of these macromolecules during PD has serious implications for the peritoneal transport of proteins, host defense, wound healing, inflammation, and fibrosis.
DNSSEC Signing Policy & Practice Statement Framework (2009)

This document presents a framework to assist writers of DNSSEC policy
and practice statements such as registry managers on both TLD and
secondary level, who have deployed DNSSEC. DNSSEC is a set of security
extensions to the DNS that allows validating DNS answers by to
establishing a 'chains of trust' from known public keys to the
data being validated. The aim of this framework is to describe an
overall policy for serving secured DNS data and key management. In
particular, the framework provides a comprehensive list of topics that
potentially (at the writer's discretion) needs to be covered in a
DNSSEC policy definition and practice statement.
Carrier diffusion degradation of modulation transfer function in charge coupled imagers (1974)

Expressions for the modulation transfer function due to minority carrier diffusion in charge coupled imagers are calculated, following the approach used by Crowell and Labuda. Both front and rear optical illumination of the charge coupled imager are considered; for the rear illumination case interference effects are included. The modulation transfer function for high energy electron excitation is also considered. In all cases, the expressions for the modulation transfer function have been evaluated using typical charge coupled imager parameters. The quantum efficiency predicted by the minority carrier diffusion model is also briefly discussed.
Gelcasting of silicon preforms for the production of sintered reaction-bonded silicon nitride (1995)

Gelcasting of silicon metal for the production of sintered reaction-bonded silicon nitride (SRBSN) was investigated in order to identify associated advantages over conventional forming techniques, i.e., die and isostatic pressing. Compacts were formed from identical powder mixtures by both gelcasting and pressing, and were nitrided and sintered to produce SRBSN ceramics using both conventional and microwave heating. Characterization of the samples included measurement of green density, green and nitrided pore structure, weight gain during nitridation, final density, microstructure, toughness, and flexural strength. It was found that a more uniform pore structure existed in the green gelcast samples. It is believed that this pore configuration aided in nitridation, and manifested itself in a more uniform final microstructure. In addition, improved mechanical properties were achieved in the gelcast samples. This improvement can be attributed to green microstructure homogeneity. An additional finding of this study was that microwave hearing combined with gelcast forming resulted in SRBSN materials with improved mechanical properties.
First Brazilian recommendation on physiotherapy with sensory motor stimulation in newborns and infants in the intensive care unit (2021)

Although all modalities have good ratings for pain or stress control, it is recommended that sensory motor stimulation procedures be tailored to the infant's specific needs and that interventions and be carried out by expert professionals.
Probing the Donor−Acceptor Proximity on the Physicochemical Properties of Porphyrin−Fullerene Dyads:  “Tail-On” and “Tail-Off” Binding Approach (2001)

A new approach of probing proximity effects in porphyrin-fullerene dyads by using an axial ligand coordination controlled "tail-on" and "tail-off" binding mechanism is reported. In the newly synthesized porphyrin-fullerene dyads for this purpose, the donor-acceptor proximity is controlled either by temperature variation or by an axial ligand replacement method. In o-dichlorobenzene, 0.1 M (TBA)ClO(4), the synthesized zincporphyrin-fullerene dyads exhibit seven one-electron reversible redox reactions within the accessible potential window of the solvent and the measured electrochemical redox potentials and UV-visible absorption spectra reveal little or no ground-state interactions between the C(60) spheroid and porphyrin pi-system. The proximity effects on the photoinduced charge separation and charge recombination are probed by both steady-state and time-resolved fluorescence techniques. It is observed that in the "tail-off" form the charge-separation efficiency changes to some extent in comparison with the results obtained for the "tail-on" form, suggesting the presence of some through-space interactions between the singlet excited zinc porphyrin and the C(60) moiety in the "tail-off" form. The charge separation rates and efficiencies are evaluated from the fluorescence lifetime studies. The charge separation via the singlet excited states of zinc porphyrin in the studied dyads is also confirmed by the quick rise-decay of the anion radical of the C(60) moiety within 20 ns. Furthermore, a long-lived ion pair with lifetime of about 1000 ns is also observed in the investigated zinc porphyrin-C(60) dyads.
Green Lewis acid catalysis in organic synthesis (2000)

Abstract New types of Lewis acids as water-stable catalysts have been developed. Metal salts such as rare earth metal triflates can be used in carbon_carbon bond-forming reactions in aqueous media. These salts can be recovered after the reactions and reused. Furthermore, Lewis acid_surfactant-combined catalysts, which can be used for reactions in water without using any organic solvents, have been also developed. Finally, Lewis acid catalysis in supercritical carbon dioxide has been successfully performed. These investigations will contribute to development of environmentally friendly Lewis acid catalysis.

Stabilization of lithium superionic conduction phase and enhancement of conductivity of LiBH4 by LiCl addition (2009)

LiBH 4 exhibits lithium superionic conduction accompanied by structural transition at around 390 K. Addition of LiCl to LiBH4 drastically affects both the transition and electrical conductivity: Transition from low-temperature (LT) to high-temperature (HT) phases in LiBH4 is observed at 370 K upon heating and the HT phase can be retained at 350–330 K upon cooling. Further, the conductivity in the LT phase is more than one or two orders of magnitude higher than that of pure LiBH4. These properties could be attributed to the dissolution of LiCl into LiBH4, suggested by in situ x-ray diffraction measurement.

Expert Learning System Network for Diagnosis of Breast Calcifications (1991)

Breast calcification diagnosis was studied by using clinical findings and computerized image processing of a mammogram in a network of trained expert learning systems (Outcome Advisor [OA]). The system was tested with records not used for training and performance was compared with radiologist. The network was 72% accurate in classifying clusters of calcifications as malignant or benign over a set of test cases radiologists had considered "hard-to-diagnose calcifications," and referred for biopsy. The radiologists had decided to conduct biopsy by selecting an equal number of positive and negative cases for the test group; thus the radiologists' performance with respect to categories of benign versus malignant was constrained to be 50/50. Statistical analysis shows only a 2% probability that the observed accuracy of 72% was a chance performance in recognizing whether a cluster is benign or malignant. The feasibility of developing a network of OAs for diagnosing breast cancer integrating digital image processing of mammograms is promising.
High-Efficiency Class-FE Tuned Power Amplifiers (2008)

The results of exact time domain analysis of the novel switched-mode tuned Class-FE power amplifiers with a parallel quarterwave transmission line are presented with analytical derivation of the optimum load network parameters. Effects of the quarterwave transmission line and collector capacitance on the current and voltage waveforms are discussed. A Class-FE power amplifier is based on the combination of a class-F operating mode with Class-E switching conditions, thus extending the Class-F operation to higher frequencies for driving signals with duty cycles D < 0.5. The ideal collector voltage and current waveforms demonstrate a possibility of 100% efficiency without overlapping between each other. A possibility of alternative load network implementation including a series quarterwave transmission line or lumped-element approximation is also considered. The switched-mode Class-FE power amplifiers with a quarterwave transmission line offer a new challenge for RF and microwave power amplification providing high-efficiency operation conditions.
Self-microemulsifying drug-delivery system for improved oral bioavailability of probucol: preparation and evaluation (2012)

The objective of our investigation was to design a self-microemulsifying drug-delivery system (SMEDDS) to improve the bioavailability of probucol. SMEDDS was composed of probucol, olive oil, Lauroglycol FCC, Cremophor EL, Tween-80, and PEG-400. Droplet sizes were determined. In vitro release was investigated. Pharmacokinetics and bioavailability of probucol suspension, oil solution, and SMEDDS were evaluated and compared in rats. Plasma drug concentration was determined by high-performance liquid chromatography. After administration of probucol suspension, plasma drug concentration was very low. Relative bioavailability of SMEDDS was dramatically enhanced in an average of 2.15- and 10.22-fold that of oil solution and suspension, respectively. It was concluded that bioavailability of probucol was enhanced greatly by SMEDDS. Improved solubility and lymphatic transport may contribute to the enhancement of bioavailability.

Control of paraffin deposition in production operations (1983)

Significant operating costs are incurred from treatments designed to remove waxy deposits from production tubing or squeeze treatments designed to inhibit wax deposition. The costs are further increased by formation damage and loss of production that may result from these treatments. Studies have shown that paraffin deposition can be prevented or greatly retarded by using chemical surfactants known as dispersants. Two specific surfactants were selected that proved to be very effective paraffin dispersants. One is oil soluble and the other is water soluble. These dispersants can be injected continuously into the well or they can be added in larger quantities in a batch treatment at specific time intervals. The choice of whether to use batch or continuous treatment is governed by the type and number of wells requiring treatment.
Effect of T5 and T6 Tempers on a Hot-Rolled WE43 Magnesium Alloy (2008)

The influence of T5 and T6 tempers at 523 K on the mechanical properties and microstructure of hot-rolled WE43 alloy has been studied. The microstructure of the alloy under various conditions was studied using an optical microscope, a transmission electron microscope, and a x-ray diffractometer. The mechanical properties were measured on a tensile testing system. The results show that the hot-rolled WE43 alloy has a substantially higher hardness and strength improvement than the cast WE43 alloy. The hot-rolled WE43 alloy with a T5 temper showed better properties than the alloy with a T6 temper because both strain hardening and age hardening increased the strength of the alloy. In addition, the size of the precipitates after a T5 temper was smaller than that after a T6 temper. The yield strength of the alloy parallel to the rolling direction was higher than that perpendicular to the rolling direction.
Improvement of some physiological responses of alfalfa (Medicago sativa L.) under in vitro salt stress using Triadimefon (2013)

This study was carried out to investigation the possibility of using Triadimefon (TRD) in order to decrease the adverse effects of salt stress on Medicago plant. Triadimefon is a member of Triazol compounds which enhances stress tolerance through physiological processes. Two cultivars of Medicago sitiva including Hamedani and Yazdi were used in this study. Plants were treated with 1, 2 and 4 mg/l TRD and 0, 100 and 140 mM NaCl. Salinity reduced fresh and dry weight of plants in both cultivars with the result of higher reduction in cv. Hamedani significantly. Salt stress also increased proline, MDA and H2O2 contents and also the activity of SOD and P5CS, and the level of P5CS ranscripts, while decreased the activity of CAT and POX in both cultivars. When plants were treated with TRD and NaCl, less proline, MDA and H2O2 accumulation occurred. Interaction of NaCl and TRD increased SOD but reduced P5CS and CAT activity. Both NaCl and TRD treatments increased P5CS transcription in cultivar Yazdi while showed less effect in Hamadani cultivar. Interaction of TRD and NaCl alleviated the negative effects of salt stress on plant growth, especially at 2 mg/l TRD. The results of the present study showed that 2 mg/l TRD was the most effective level to alleviate the negative effects of NaCl treatment on Medicago sativa plants.
Ion conduction in zwitterionic-type molten salts and their polymers (2001)

We synthesized a series of imidazolium cations containing covalently-bound anionic sites, such as sulfonate or sulfonamide groups. These zwitterionic imidazolium salts were found to form molten salts just like ordinary imidazolium salts. However, regardless of the high ion density, these ions cannot migrate along potential gradients induced in the bulk. This is a new and unique characteristic in molten salts. When other salts were added to this, the ions generated from the newly added salts were able to behave as carrier ions. The ionic conductivity of a pure molten salt was 10−9 S cm−1 at 25 °C, but jumped to 10−5 S cm−1 by adding an equimolar amount of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) at 50 °C. The zwitterionic salt having a sulfonamide group instead of sulfonate had an ionic conductivity of 10−4 S cm−1 at 50 °C after adding an equimolar amount of LiTFSI. These zwitterionic imidazolium salts having vinyl groups were synthesized and polymerized. In spite of their rubber-like properties they showed excellent ionic conductivities of around 10−5 S cm−1 at 50 °C following the addition of an equimolar amount of LiTFSI to the imidazolium cation unit.
