Interfacing spherical harmonics and room simulation algorithms (2012)

Room acoustic simulation by using geometrical acoustics is usually implemented with binaural receivers. Wave models such as FEM are easily applicable with binaural interfaces as well. This way, however, the signals are restricted to a specific set of HRTF, and a tedious task is to adapt the results to a proper reproduction system with very limited possibilities of listener individualization. With a more general interface such as spherical harmonics, room acoustic spatial data could be created in intermediate solutions. In post-processing this can lead to various binaural representations or to reproduction with Ambisonics (Dalenbäck, ICA 1995). In this paper it is discussed how standard routines in geometrical acoustics must be changed in order to implement multi-channel spherical microphone arrays. Furthermore, the corresponding output data can be multi-channel time signals or temporal SH coefficients or any other suitable spectral format. The amount of data and signal processing affects CPU time and memory. The discussion therefore is focused on feasibility and on consequences on the real-time performance on the one hand, and on the spatial quality of the room response, on the other.

Microwave plasma sources for use in space plasma physics experimentation (2002)

Summary form only given. We have developed two microwave plasma sources most useful in approximating ionospheric space plasma environments because of the low electron temperatures (<2 eV) and adjustable densities (10/sup 4/-10/sup 8/ cm/sup -3/). Both of these sources employ conventional microwave oven magnetrons and are easy to construct and exhibit stable operation over a wide range of neutral gas flow rates and electron densities. Although the production mechanism of the plasma is the same in both cases (microwave cavity resonance), the designs of the two sources are quite different. We report on the use of these types of sources in space plasma experimentation in the Space Physics Simulation Chamber (SPSC) at the Naval Research Laboratory. We will describe construction of these sources and improvements to the design, including an increased surface area to provide a more uniform plasma across the available experimental area.

Experiences in Commissioning of Cold Rolling Mill Flatness Control Systems (1992)

Flatness control in metal strip rolling involves dealing with the measurement, control, display and performance analysis of a distributed function rather than a scalar variable. Solutions for each of these issues are discussed and a number of novel ideas presented. A brief history of cold rolling flatness control system development is provided, followed by a discussion of the motivation for a small domestic automation company to enter the export market in this area. The approach adopted in commissioning a number of sophisticated model-based systems is described and the level of improvement achieved is outlined.
Modification of ASTM F 1671-97a, Resistance of Materials to Penetration by Blood-Borne Pathogens, for Use with Elastomeric Materials (2000)

Abstract A modification to ASTM F 1671-97a, Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Blood-Borne Pathogens Using Phi-X174 Bacteriophage Penetration as a Test System, was developed to allow evaluation of elastomeric materials having small tears. The original method provides for a flat, open-mesh support screen to prevent expansion of such materials. While natural latex rubber specimens with open, laser-drilled holes ⩾1 µm fail this test by allowing virus penetration, nitrile-butadiene rubber specimens with small tears (20 to 45 µm) pass. A stainless steel wire cloth support screen with a hemispherical-like dome, in lieu of the flat screen, provided controlled expansion and allowed detection of defective specimens with tears. The data also suggest a similar modification to enhance ASTM F 1670-97, Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Synthetic Blood.
Objects, Motions, and Paths: Spatial Language in Children With Williams Syndrome (2003)

Abstract The acquisition of spatial language is often assumed to be built upon an early-emerging system of nonlinguistic spatial knowledge. We tested this relationship by examining spatial language in children with Williams syndrome (WS), a rare genetic disorder that gives rise to severe nonlinguistic spatial deficits together with relatively spared language. Twelve children with WS, 12 normally developing mental-age matched children, and 12 normal adults described 80 videotaped motion events. Children with WS showed substantial control over key linguistic components of the motion event, including appropriate semantic and syntactic encoding of Figure and Ground objects, Manner of Motion, and Path. The expression of Path, although surprisingly spared, was more fragile among children with WS in contexts plausibly related to their nonlinguistic spatial deficit. The results show strong preservation of the formal aspects of spatial-linguistic knowledge and suggest that the nonlinguistic spatial deficits shown by children with WS have, at most, limited effects on their spatial language. These findings have implications for the relationship between spatial language and other aspects of spatial cognition.
Exclusion of <i>PTEN</i>, <i>CTNNB1</i>, and <i>PTCH</i> as candidate genes for Birt-Hogg-Dube syndrome (2002)

In 1977, Birt, Hogg, and Dube described a kindred in which 15 of 70 members over three generations exhibited multiple, small, grey skin coloured, dome shaped papules distributed over the face, neck, and upper trunk inherited in an autosomal dominant pattern.1 Histological examination of these lesions showed fibrofolliculomas, trichodiscomas, and acrochordons. This triad has become known as Birt-Hogg-Dube (BHD) syndrome. Since the initial report, other cases have been described.2–13

The cutaneous manifestations of BHD, which typically appear during the third or fourth decade of life, have been associated with renal carcinoma,2,5 spontaneous pneumothorax,2,6 and colonic polyps.3,4 Toro et al 2 recently reported three extended kindreds in whom renal neoplasms and BHD segregated together. Two kindreds had renal oncocytomas and a third had a variant of papillary renal cell carcinoma. Renal neoplasms can be familial or sporadic. Four types of familial renal neoplasms have been well described: (1) clear cell renal carcinoma associated with haemangioblastomas of the brain, spine, and eye owing to mutations in the von Hippel-Lindau (VHL) disease tumour suppressor gene,4 (2) clear cell renal carcinoma associated with constitutional, balanced translocations involving the short arm of chromosome 3,15–17 (3) papillary renal cell carcinoma associated with germline mutations in the tyrosine kinase domain of the MET proto-oncogene,18 and (4) renal oncocytoma.19

In this study, we report an extended family that we evaluated for PTEN , CTNNB1 , and PTCH as candidate genes for BHD and renal cancer. These genes were selected for study because mutations in each are associated with a disorder that has clinical features that overlap BHD and because each of these disorders carries an increased risk for internal malignancy. We used a candidate gene approach. We first performed sequencing analysis, but no mutations …
Group C Rotavirus Infection and Infiltration (1990)

We recently found many cases of gastroenteritis involving older children and sometimes other members of their families. We suspected epidemiological infiltration of an atypical rotavirus (RV). PAGE analysis of 130 cases in 1985 and 1986 revealed that the RNA profiles were similar to that of group C RV in 12 cases. We performed IEM analysis on one of the strains and found it to be group C. The group C RV was detected for 2 months toward the end of the outbreak of group A RV infection. The ages of the group C RV infected patients were 4 years or older. We also studied the prevalence of antibody to group C in the stored sera that had been collected since 1971. Antibody was seldom found in the sera of patients under 3 years of age but it was found in 20-40% of those who were 4 years or older. The clinical manifestations of the group C RV infection were similar to those of group A, except that body temperature was slightly lower and other symptoms were generally milder.

A voltage-controlled oscillator for a 300 MHz high-temperature transceiver realized in 0.5 μm SOS technology (2002)

This paper presents a study of the design of a 300-MHz voltage-controlled oscillator (VCO) implemented in a 0.5-/spl mu/m Silicon-On-Sapphire (SOS) CMOS technology. The circuit is designed for use in a frequency synthesizer in a high-temperature (200/spl deg/C) transceiver. Several issues relating to high-temperature applications as well as the overall system architecture are presented. The design of the VCO is emphasized in this paper, but a programmable divider, phase detector/charge pump and loop filter were also designed for use in closed-loop tests of the VCO and are briefly discussed. Prototyping and testing procedures are discussed and the results of the prototyped circuits are evaluated.

Can Automated Scoring Surpass Hand Grading of Students' Constructed Responses and Error Patterns in Mathematics? (2007)

A unique online parsing system that produces partial­credit scoring of students’ constructed responses to mathematical questions is presented. The parser is the core of a free college readiness website in mathematics. The software generates immediate error analysis for each student response. The response is scored on a continuous scale, based on its overall correctness and the fraction of correct elements. The parser scoring was validated against human scoring of 207 real­world student responses (r = 0.91). Moreover, the software generates more consistent scores than teachers in some cases. The parser analysis of students’ errors on 124 additional responses showed that the errors were factored into two groups: structural (possibly conceptual), and computational (could result from typographical errors). The two error groups explained 55% of students’ scores variance (structural errors: 36%; computational errors: 19%). In contrast, these groups explained only 33% of the teacher score variance (structural: 18%; computational: 15%). There was a low agreement among teachers on error classification, and their classification was weakly correlated to the parser’s error groups. Overall, the parser’s total scoring closely matched human scoring, but the machine was found to surpass humans in systematically distinguishing between students’ error patterns.

Chemistry of dimethyl sulfide in the equatorial Pacific atmosphere (1996)

A field study of the chemistry of dimethyl sulfide (DMS) was conducted on the island of Kiritimati (Christmas Island) during July and August, 1994. This island is located at 2°N, 157°W approximately 2000 km south of Hawaii. We obtained a very repeatable diurnal variation for both DMS and sulfur dioxide (SO 2 ) during two 5‐day and one 2‐day experiments. Near sunrise DMS was about 200 pptv. It decreased to about 120 pptv by late afternoon. During the daytime SO 2 increased from about 20 pptv to about 75 pptv. At night DMS increased and SO 2 decreased almost linearly. About 62% of the DMS was converted to SO 2 . DMS was emitted from the ocean at an average flux of 3.7 × 10 13 molecules m −2 s −1 . The average dry deposition velocity of SO 2 was 6.8 mm sec −1 . Most of the SO 2 appeared to be lost to the ocean although a comparable but not significantly larger flux to aerosol cannot be ruled out. Dimethyl sulfoxide was in the range 10 to 50 pptv with a mean of about 25 pptv. Dimethyl sulfone was in the range 0 to 15 pptv with a mean of about 3 pptv. There was no diurnal trend in either species. A much smaller fraction of the DMS was converted to dimethyl sulfone than dimethyl sulfoxide.
Effect of Flue Gas Desulfurization Residue on Plant Establishment and Soil and Leachate Quality (2001)

Effects on soil quality and crop establishment after incorporation of flue gas desulfurization by-product (FGD) into soil as an amendment was assessed in a mesocosm study. Mesocosm units received applications equivalent to 0, 2.5, 5.0, 7.5, and 10% FGD residue [0, 25, 50, 75, and 100 tons acre(-1)]. Germination, biomass production, and elemental composition of corn (Zea mays L. var. Dekalb DK-683), soybean [Glycine max (L.) Merr. var. Haskell Pupa 94], radish (Raphanus sativus L. var. Sparkler), and cotton (Gossypius hirsutus L. var. Deltapine 51) were determined. The quality of leachates and soil were also determined periodically. Flue gas desulfurization residue did not affect germination and all application rates stimulated aboveground biomass. Plants grown in FGD-amended soil contained significantly elevated tissue concentrations of As, B, Se, and Mo. The FGD residue elevated surface soil pH from 5.5 (Control) to 8.1 (at 10% FGD). Leachate pH was unaffected by FGD, but salinity rose sharply with increasing application rates of FGD. Leachates contained higher concentrations of B, with small increases in Se and As. Flue gas desulfurization residue application caused an increase in total B, As, Mo, Se, and extractable Ca in the soil, but decreased Mn and Zn. Using FGD residues could have beneficial effects on crop establishment without detrimental effects on soil or leachate quality, at an optimum rate of approximately 2.5%. This material could alleviate surface acidity, and B and Mo deficiencies in plants.
Identifying the Recognition Site for Selective Trapping of <sup>99</sup>TcO<sub>4</sub><sup>–</sup> in a Hydrolytically Stable and Radiation Resistant Cationic Metal–Organic Framework (2017)

Effective and selective removal of <sup>99</sup>TcO<sub>4</sub><sup>-</sup> from aqueous solution is highly desirable for both waste partitioning and contamination remediation purposes in the modern nuclear fuel cycle, but is of significant challenge. We report here a hydrolytically stable and radiation-resistant cationic metal-organic framework (MOF), SCU-101, exhibiting extremely fast removal kinetics, exceptional distribution coefficient, and high sorption capacity toward TcO<sub>4</sub><sup>-</sup>. More importantly, this material can selectively remove TcO<sub>4</sub><sup>-</sup> in the presence of large excesses of NO<sub>3</sub><sup>-</sup> and SO<sub>4</sub><sup>2-</sup>, as even 6000 times of SO<sub>4</sub><sup>2-</sup> in excess does not significantly affect the sorption of TcO<sub>4</sub><sup>-</sup>. These superior features endow that SCU-101 is capable of effectively separating TcO<sub>4</sub><sup>-</sup> from Hanford low-level waste melter off-gas scrubber simulant stream. The sorption mechanism is directly unraveled by the single crystal structure of TcO<sub>4</sub><sup>-</sup>-incorporated SCU-101, as the first reported crystal structure to display TcO<sub>4</sub><sup>-</sup> trapped in a sorbent material. A recognition site for the accommodation of TcO<sub>4</sub><sup>-</sup> is visualized and is consistent with the DFT analysis results, while no such site can be resolved for other anions.
Coacervation of Hydrophobically Modified Polyanions by Association with Nonionic Surfactants in Water (2002)

Complexes of random copolymers of sodium 2-(acrylamido)-2-methylpropanesulfonate and N-dodecylmethacrylamide (DodMAm) (poly(A/Dx), where x denotes the mol % content of DodMAm) and n-dodecyl hexa(ethylene glycol) monoether (C12E6) exhibited a liquid−liquid phase separation (coacervation) when poly(A/Dx) with x ≈ 50 mol % and C12E6 were mixed in water in the presence of a sufficiently high concentration of added NaCl ([NaCl]). Phase diagrams obtained by turbidimetric titrations indicated that coacervation occurred only within a limited concentration regime both for the polymer and surfactant. Coacervation occurred more easily at higher [NaCl]; [NaCl] should be higher than ca. 0.2 M at 25 °C for coacervation to occur. The cloud points of a mixture of poly(A/D48) and C12E6 at varying [NaCl] suggested that the dominant effects of added NaCl were the shielding effect of electrostatic repulsion between sulfonate moieties in poly(A/D48) at lower [NaCl] and an enhancement of hydrophobic interaction caused by added salt at higher [NaCl]. From the intra- and interpolymer nonradiative energy transfer and quasielastic light scattering data, it was concluded that as the concentration of either of the three components (i.e., polymer, surfactant, and salt) is increased toward a phase boundary for coacervation, the size of poly(A/D48)−C12E6 soluble complexes, in which C12E6 micelles act as cross-linking junctions of different polymer chains, increases gradually at first and then abruptly near the phase boundary, ending up with coacervation at a higher concentration of the component. On the basis of these experimental data, we discussed a possible mechanism for the coacervation of poly(A/D48) with C12E6.
Schwannoma-derived growth factor promotes the neuronal differentiation and survival of PC12 cells. (1992)

Schwannoma-derived growth factor (SDGF) was initially isolated from schwannoma cells as a mitogen for glial cells and fibroblasts. The present data show that SDGF causes the morphological and molecular differentiation of rat PC12 cells in a manner similar to, but distinguishable from nerve growth factor (NGF). It also promotes PC12 survival in serum-free conditions. SDGF induced changes include neurite outgrowth and the induction of the mRNAs for GAP-43 and transin, proteins which are highly expressed in axons. In addition, both SDGF and NGF induce the transcription factor, NGFI-A. The time course of the response to SDGF is similar to that for NGF. Gap-43 mRNA induction by both SDGF and NGF is inhibited by dexamethasone, but dexamethasone has no effect on NGFI-A mRNA synthesis. These observations show that SDGF has a differentiation and survival promoting effect on PC12 cells in addition to its mitogenic activity on glial cells and fibroblasts.
