Application of techniques to identify coal-mine and power-generation effects on surface-water quality, San Juan River basin, New Mexico and Colorado (1987)

Numerous analytical techniques were applied to determine water quality changes in the San Juan River basin upstream of Shiprock , New Mexico. Eight techniques were used to analyze hydrologic data such as: precipitation, water quality, and streamflow. The eight methods used are: (1) Piper diagram, (2) time-series plot, (3) frequency distribution, (4) box-and-whisker plot, (5) seasonal Kendall test, (6) Wilcoxon rank-sum test, (7) SEASRS procedure, and (8) analysis of flow adjusted, specific conductance data and smoothing. Post-1963 changes in dissolved solids concentration, dissolved potassium concentration, specific conductance, suspended sediment concentration, or suspended sediment load in the San Juan River downstream from the surface coal mines were examined to determine if coal mining was having an effect on the quality of surface water. None of the analytical methods used to analyzed the data showed any increase in dissolved solids concentration, dissolved potassium concentration, or specific conductance in the river downstream from the mines; some of the analytical methods used showed a decrease in dissolved solids concentration and specific conductance. Chaco River, an ephemeral stream tributary to the San Juan River, undergoes changes in water quality due to effluent from a power generation facility. The discharge in the Chaco River contributes about 1.9% of the average annual discharge at the downstream station, San Juan River at Shiprock, NM. The changes in water quality detected at the Chaco River station were not detected at the downstream Shiprock station. It was not possible, with the available data, to identify any effects of the surface coal mines on water quality that were separable from those of urbanization, agriculture, and other cultural and natural changes. In order to determine the specific causes of changes in water quality, it would be necessary to collect additional data at strategically located stations. (Author 's abstract)
Dynamic Control of a Space Robot System With No Thrust Jets Controlled Base (1991)

In this paper we discuss dynamic control of a free-flying space robot system where the base attitude is not controlled by thrust jets. Without external forces and moments, the system is governed by linear and angular momentum conservation laws. We first derive the system dynamic formulations in joint space and in inertia space, based on Lagrangian dynamics. Then we discuss the fact that dynamics of a space robot system can not be linearly parameterized, as opposed to the case of a fixed-based robot. Revealing this property is significant since the linearity of parameterization has been used as a prerequisite for various adaptive and nonlinear control schemes currently used in the robot control. Based on the dynamic model of the space robot system, a simple linear control scheme is presented for the normal regulation problem for tasks in space, such as holding lights for illuminating objects or handing an astronaut tools in extra-vehicular activity. A globally stable dynamic control scheme is proposed for trajectory tracking applications, such as catching moving objects or structure inspection for the space station. The dynamic control algorithm exhibits a fast and accurate motion response even when the mass/ inertia ratio of the base with respect to the robot is low. The effectiveness of the proposed algorithms are demonstrated by simulation studies.
Long-Term Transgene Expression within the Anterior Pituitary Gland<i>in Situ</i>: Impact on Circulating Hormone Levels, Cellular and Antibody-Mediated Immune Responses<sup>1</sup> (2001)

Adenoviral vectors have been identified as useful tools for gene transfer to the pituitary gland with the aim of providing therapeutic treatments for pituitary diseases. Although successful adenovirus-mediated gene transfer to the pituitary has been shown, the duration of transgene expression, local immune responses and consequences on circulating pituitary hormone levels have not been investigated. These are critical not only for the successful implementation of these gene transfer techniques both for physiological and/or therapeutic applications but also for assessing the safety of these approaches. We have therefore assessed duration and levels of transgene expression 3 days, 14 days, 1, 2, and 3 months after delivery of adenoviruses expressing herpes simplex virus type 1 thymidine kinase (HSV1-TK), under the control of the major immediate early human cytomegalovirus (RAd-hCMV/TK) or human PRL (RAd-hPrl/TK) promoters, to the anterior pituitary (AP) gland in situ. The presence of vector genome and cellular immune infiltrates within the AP gland were also studied along with the levels of circulating anti-adenovirus neutralizing antibodies and AP hormones in sera. Ubiquitous or cell-type specific expression of HSV1-TK within the AP gland was seen from RAd-hCMV/TK and RAd-hPrl/TK respectively at all time points, although a reduction in expression was seen over time. PCR amplification of HSV1-TK specific sequences showed the persistence of adenoviral genomes for up to 3 months. Analysis of the AP showed the presence of a virus-induced inflammation that peaked around day 14 and was resolved between 2-3 months. ED1-positive macrophages, CD8-positive T-cells and CD161-positive NK cells were identified up to 1 month after virus administration. A virus-induced humoral immune response was also present as anti-adenovirus neutralizing antibodies were detected from 14 days after virus administration. Levels of circulating pituitary hormones were unaffected by virus administration with the exception of the stress hormone ACTH which was increased at 3 days but normalized by 14 days. In conclusion, our data indicates that adenovirus-mediated delivery to the AP gland in situ may be a useful tool for the treatment of pituitary diseases as no major cytotoxicity or disruption of AP hormonal functions are seen. Despite of this, further developments to this approach still need to be made to combat the reduced transgene expression seen over time and the induction of virus-induced immune responses.

AUTOMATED LANDMARK DETECTION ON X-RAY CEPIiALOGRAMS (1991)

Accurate, reliable, and reproducible data are crucial to research investigators and clinicians who evaluate growth and plan treatment on the basis of measurements from skull X-ray images. Automating the process of landmark location on these Xray images may produce higher quality data and improve data capture productivity. A method is proposed for automating landmark location and data extraction from craniofacial x-ray images using neural networks and match filtering techniques.
Density fluctuation in asymmetric nozzle plumes and correlation with far field noise (2001)

A comparative experimental study of air density fluctuations in the unheated plumes of a circular, 4-tabbed-circular, chevron-circular and 10-lobed rectangular nozzles was performed at a fixed Mach number of 0.95 using a recently developed Rayleigh scattering based technique. Subsequently, the flow density fluctuations are cross-correlated with the far field sound pressure fluctuations to determine sources for acoustics emission. The nearly identical noise spectra from the baseline circular and the chevron nozzles are found to be in agreement with the similarity in spreading, turbulence fluctuations, and flow-sound correlations measured in the plumes. The lobed nozzle produced the least low frequency noise, in agreement with the weakest overall density fluctuations and flow-sound correlation. The tabbed nozzle took an intermediate position in the hierarchy of noise generation, intensity of turbulent fluctuation and flow-sound correlation. Some of the features in the 4-tabbed nozzle are found to be explainable in terms of splitting of the jet in a central large core and 4 side jetlets.
The Neuroimaging and Clinical Spectrum of Neurofibromatosis 2 (1996)

Neurofibromatosis 2 (NF2) is an autosomal dominant disease predisposing to multiple tumors of the central and peripheral nervous system. Bilateral vestibular schwannomas are the hallmark of the disease. To define the clinical spectrum of the disease, we performed gadolinium-enhanced magnetic resonance imaging of the brain and spine as well as neurological, dermatological, and ocular examinations in 48 patients with NF2 diagnosed with the National Institutes of Health diagnostic criteria. Patients were ascertained from patient workshops and publications and from referral as a result of vestibular schwannoma surgery. Vestibular schwannomas were found in 46 patients (96%, 43 bilateral and 3 unilateral), spinal tumors were found in 43 (90%), posterior subcapsular cataracts were found in 30 (63%), meningiomas were found in 28 (58%), and trigeminal schwannomas were found in 14 (29%). The presenting symptoms included hearing loss or tinnitus in 15 patients (31%), multiple or nonspecific symptoms in 15 (31%), skin tumors in 12 (25%), and ocular symptoms in 6 (13%). When the complete spine was imaged, spinal tumors were more common in patients with NF2 than has previously been reported. This is a noteworthy finding, because spinal tumors are a major cause of NF2 morbidity and mortality.
Single-shot full-complex spectrum spectrometer-based OCT (2011)

An efficient technique of simultaneous obtaining of quadrature spectral components of interference signal in spectrometer-based OCT is proposed. The components are obtained in air-spaced non-polarization interferometer by partition of reference beam onto two parts and using an achromatic phase shifter. Several setups of phase sifter are described and compared.
The Crankshaft Phenomenon (1989)

We reviewed 40 spinal fusions done prior to Risser stage I for idiopathic and paralytic scoliosis to evaluate postoperative curve progression. The 39 patients who had posterior fusion alone had progressive angulation and rotation of the spine over the postoperative follow-up period. The more immature the patient, the greater the resultant progression. This progression is an inevitable consequence of continued anterior spinal growth in the presence of a posterior fusion, and occurs without pseudarthrosis or hardware failure. Younger patients may require anterior and posterior fusion to achieve stable correction.
MÖSSBAUER PROPERTIES OF SYNTHETIC ANALOGS OF ACTIVE SITES OF THE IRON-SULFUR PROTEINS (1974)

Mössbauer spectroscopy of the synthetic tetramers [Fe4S4(SR)4]2- (R = alkyl, aryl) and the corresponding trianions obtained by one-electron reduction, when compared with available data for 4-Fe and 8-Fe iron-sulfur proteins, shows that these tetramers are electronic analogs of the active sites of the proteins.
IMPACT OF POSITIVE BLADDER NECK MARGIN ON THE BIOCHEMICAL RECURRENCE AFTER RADICAL PROSTATECTOMY (2009)

Opinions about the optimal lymph node dissection (LND) template in prostate cancer differ. Drainage and dissemination patterns are not necessarily identical.To present a precise overview of the lymphatic drainage pattern and to correlate those findings with dissemination patterns. We also investigated the relationship between the number of positive lymph nodes (LN+) and resected lymph nodes (LNs) per region.Seventy-four patients with localized prostate adenocarcinoma were prospectively enrolled. Patients did not show suspect LNs on computed tomography scan and had an LN involvement risk of ≥10% but ≤35% (Partin tables) or a cT3 tumor.After intraprostatic technetium-99m nanocolloid injection, patients underwent planar scintigraphy and single-photon emission computed tomography imaging. Then surgery was performed, starting with a sentinel node (SN) procedure and a superextended lymphadenectomy followed by radical prostatectomy.Distribution of scintigraphically detected SNs and removed SNs per region were registered. The number of LN+, as well as the percentage LN+ of the total number of removed LNs per region, was demonstrated in combining data of all patients. The impact of the extent of LND on N-staging and on the number of LN+ removed was calculated.A total of 470 SNs were scintigraphically detected (median: 6; interquartile range [IQR]: 3–9), of which 371 SNs were removed (median: 4; IQR: 2.25–6). In total, 91 LN+ (median: 2; IQR: 1–3) were found in 34 of 74 patients. The predominant site for LN+ was the internal iliac region. An extended LND (eLND) would have correctly staged 32 of 34 patients but would have adequately removed all LN+ in only 26 of 34 patients. When adding the presacral region, these numbers increased to 33 of 34 and 30 of 34 patients, respectively.Standard eLND would have correctly staged the majority of LN+ patients, but 13% of the LN+ would have been missed. Adding the presacral LNs to the template should be considered to obtain a minimal template with maximal gain.This manuscript was invited based on the 2011 European Association of Urology meeting in Vienna.
Movement EEG classification using parallel Hidden Markov Models (2016)

In this contribution we examine the use and utility of parallel HMM classification in single-trial movement-EEG classification of index finger reaching and grasping movement. Parallel HMMs allow us to easily utilize the information contained in multiple channels. Using HMM classifier output in parallel from examined EEG channels we have been able to achieve as good a classification score as with single electrode results, further we do not rely on a single electrode giving persistently good results. Our parallel approach has the added benefit of not having to rely on small inter-session variability as it gives very good results with fewer classifier parameters being optimized. Without any classification optimization we can get a score improvement of 11.2% against randomly selected physiologically relevant electrode. If we use subject specific information we can further improve on the reference score by 1%, achieving a classification score of 84.2±0.7%.
Measured results of flashover characteristics of distribution line insulators for sustaining insulated cable (2008)

This paper describes experimental results of flashover characteristics of a medium voltage insulator to support an insulated cable using an impulse voltage generator. This experiment is targeted for direct lightning strokes to a distribution line. The lightning impulse voltage is applied to a cross arm to represent the direct lightning stroke. A flashover on the insulator occurs from the arm to the cable at first, and then the surface discharge develops along the cable. If the applied voltage is sufficiently high, the breakdown in the insulation of the cable occurs. This final stage corresponds to a line fault.
Dexamethasone and 8-bromo-cyclic AMP depress the incorporation of [3H]thymidine into mouse condylar cartilage by different pathways (1986)

We examined whether cyclic AMP (cAMP) affects the incorporation of [3H]thymidine into cartilage cells and, if so, whether this action could be related to the inhibitory effect of glucocorticoid hormones on the growth of ossifying cartilage. Incorporation of [3H]thymidine into trichloroacetic acid-precipitable material by mouse cartilage was measured concomitantly with the concentration of cAMP. Dexamethasone (1 mumol/l) significantly (P less than 0.05) depressed the incorporation of [3H]thymidine. The cAMP analogue 8-bromo-cAMP (0.01-1 mmol/l) also depressed the incorporation of the radionucleotide in a dose-dependent fashion. When various concentrations of 8-bromo-cAMP were added with dexamethasone (1 mumol/l), no apparent changes took place compared with the effect of dexamethasone alone. The phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine (0.2-1 mmol/l) elicited an inhibitory effect on [3H]thymidine incorporation and a stimulatory influence on cartilage cAMP concentrations. Dexamethasone, at doses (0.01-1 mumol/l) causing significant inhibition of [3H]thymidine incorporation, failed to increase cartilage levels of cAMP. It seems, therefore, that the depressive effect of dexamethasone on [3H]thymidine incorporation in condylar cartilage is not mediated through an increase of cAMP in the tissue.
Ensuring quality in process design: Tracing requirements to people and systems (2014)

Information systems are implemented to support business processes to enable efficiency through automation while maintaining the effectiveness of the process. The focus often is to reduce the cost and time in performing business processes. Business Processes automated using workflow systems often ignore the structure and responsibility of people who are integral to it. This paper introduces an approach to trace the quality required of the people and systems to their responsibilities, thereby highlighting the people centric view of processes. The responsibilities that people have, been further classified into Governance, Management, Administration and Knowledge work areas to ensure completeness and further responsibility delineation. The approach also builds in the mechanism to assign responsibilities to people and systems. This includes differentiation of the responsibilities as specific and generic; and their relationship with roles.

Hot-electron magnetophonon resonance in n-type germanium in pulsed high magnetic fields up to 40 T (1992)

Hot-electron magnetophonon resonances in n-type Ge samples have been investigated in pulsed high magnetic fields up to 40 T for B//I//(110), (111) and (100) directions at a fixed temperature of 20 K. Owing to the high magnetic fields, an observation of almost all resonance series of both intervalley and intravalley processes from the first harmonic number (Landau quantum number N=1) has become possible for the first time. The resonant cooling process of electrons was consistently understood by taking into account an initial energy distribution of electrons, anisotropy of the effective mass at each valley and the mobility change toward the current direction.
PERFORMANCE EVALUATION OF A CONVENTIONAL NAUTAMIXER APPLIED AS A DIRECT DRYER - EMPIRICAL MODEL (1991)

ABSTRCT This paper is the second part of (1)and it shows an attempt to define a suitable model, which would make it possible to predict the drying rate for pastelike and bulk materials in a conventional Nautamixer applied as a direct dryer. As it was shown in (1), (2), (3) all influential variables were studied, and from the results it can be seen that the system is highly complex. By means of system simplification an empirical model is defined, suitable for drying rate calculation for this type of dryer, in the accuracy range of ±25%. For the practical purpose, it seems that this simple model offers a reliable starting point for drying process design for similar systems.
