Variable Magnetization Machine in Electrified Vehicle Application (2016)

SUMMARY This paper describes variable magnetization machines, which are capable of varying the magnetization state (MS) of permanent magnets during operation. A pulse current on the stator windings creates a magnetic field on the rotor; this can be used to manipulate the MS of the rotor magnets. Regulating the MS according to the machine operating condition can reduce machine losses. A proof‐of‐principle machine was designed and fabricated. A series of experiments was conducted to evaluate the torque–speed envelope and efficiency contours of the fabricated machine. A full‐scale machine was then designed with a modified magnetic circuit for application to an electric vehicle and evaluated using finite element analysis. A control strategy for the MS during machine operation is proposed, and the losses during a driving cycle with the strategy were evaluated.
Syntheses of Dichloroacetyl Derivatives of <i>p</i>-Nitrophenylalkylamines and their Related Compounds (1952)

In order to test their antiviral and antibacterial activities, dichloracetyl derivatives of p-nitrophenylalkylamines and their related compounds were prepared. Their physical constants and antibacterial activities are given in the Tables I and II, respectively.
Melanoma (1981)

Three instances of depigmentation occurring in children with congenital large nevocytic nevi are reported. Serologic studies for tumour-associated antigens to melanoma were performed by indirect immunofluorescence and complement fixation on these patients and others with benign melanocytic disorders. Positive reactivity in several children was observed. The small numbers studied and lack of uniformity of other testing methods leave open the question of relevance of such reactivity to malignant conversion or protection in congenital nevi.

Microwave characterization of low temperature cofired ceramic (2002)

The use of low temperature cofired ceramic (LTCC) materials for the manufacture of high performance microelectronic packages operating at very high frequencies has found widespread acceptance due to LTCC's durability, compactness and manufacturability. Extensive effort has been devoted to the characterization of the electrical performance of the dielectric and associated conductor materials to determine and predict performance when constructing electronic packages that operate over a broad band of frequencies from DC through high speed digital to the microwave and millimeter bands. This effort has focused on several different areas, including the effect of operating frequency on the bulk dielectric properties of the ceramic and the electrical properties of associated thick film materials, particularly conductors. The interaction of these materials during processing, has been investigated, to determine the interdependence of these characteristics, so that both design rules and processing guidelines for particular package configurations (such as microstrip and stripline) and applications may be optimized. The Ferro A6-M ceramic, has demonstrated low dielectric constant and low dielectric loss at a wide range of frequencies, is compatible with low cost, high performance conductor materials, such as silver, and may also be used in mixed metal configurations with combinations of gold and silver conductors, in applications where such an approach is necessary. This paper reviews some of the results which have been determined in electrical characterizations such as these and proposes new electrical evaluations that may prove useful in the future.
Aligner optimization increases accuracy and decreases compute times in multi-species sequence data (2017)

As sequencing technologies have evolved, the tools to analyze these sequences have made similar advances. However, for multi-species samples, we observed important and adverse differences in alignment specificity and computation time for bwa- mem (Burrows-Wheeler aligner-maximum exact matches) relative to bwa-aln. Therefore, we sought to optimize bwa-mem for alignment of data from multi-species samples in order to reduce alignment time and increase the specificity of alignments. In the multi-species cases examined, there was one majority member (i.e. <i>Plasmodium falciparum</i> or <i>Brugia malayi</i>) and one minority member (i.e. human or the <i>Wolbachia</i> endosymbiont <i>w</i>Bm) of the sequence data. Increasing bwa-mem seed length from the default value reduced the number of read pairs from the majority sequence member that incorrectly aligned to the reference genome of the minority sequence member. Combining both source genomes into a single reference genome increased the specificity of mapping, while also reducing the central processing unit (CPU) time. In <i>Plasmodium</i>, at a seed length of 18 nt, 24.1 % of reads mapped to the human genome using 1.7±0.1 CPU hours, while 83.6 % of reads mapped to the <i>Plasmodium</i> genome using 0.2±0.0 CPU hours (total: 107.7 % reads mapping; in 1.9±0.1 CPU hours). In contrast, 97.1 % of the reads mapped to a combined <i>Plasmodium-</i>human reference in only 0.7±0.0 CPU hours. Overall, the results suggest that combining all references into a single reference database and using a 23 nt seed length reduces the computational time, while maximizing specificity. Similar results were found for simulated sequence reads from a mock metagenomic data set. We found similar improvements to computation time in a publicly available human-only data set.
Quantitation of a transformation-sensitive, adhesive cell surface glycoprotein. Decrease of several untransformed permanent cell lines. (1977)

We have quantitated the transformation-sensitive, cell surface LETS glycoprotein on many untransformed cell types. By SDS-polyacrylamide gel electrophoresis, this trypsin-sensitive iodinatable glycoprotein comprises 1-3% of total cellular protein of the seven early passage cell types tested. In contrast, it constitutes less than 0.15% of the protein in four of six continuous cell lines. This decrease is reflected in alterations both in [14C]glucosamine labeling and in the immunofluorescent staining of early passage vs. these four permanent cell lines. These results help to clarify previous experiments in which CSP, a purified LETS protein, partially restored a fibroblastic phenotype to cells transformed by tumor viruses. These findings also indicate that a major decrease in this cell surface glycoprotein can occur in the establishment of a continuous cell line without resulting in cellular transformation.
<i>tert</i>-Butyl 3-oxo-2-oxa-5-azabicyclo[2.2.1]heptane-5-carboxylate (2008)

The title compound, C(10)H(15)NO(4), also known as N-tert-butyl-oxycarbonyl-allohydr-oxy-l-proline lactone, is quite similar to N-acetyl-allohydr-oxy-l-proline lactone [Lenstra, Petit & Geise (1979 ▶). Cryst. Struct. Commun. 8, 1023-1029], whereby both carbonyl groups point roughly in the same direction because of the trans conformation of the peptide bond.
Dehn-Sommerville relations, upper bound theorem, and levels in arrangements (1993)

In this note, we generalize the h-vector for simple, bounded convex polytopes [14] to the h-matrix for simple, bounded k-complexes. We observe that the h-matrix is invariant with respect to the defining linear function, and that the Dehn-Sommerville relations and McMullen's Upper Bound Theorem [13] for convex polytopes follow from the invariance ofthe 0-th row and column of this matrix. The invariance of the other entries in the h-matrix should, perhaps, be investigated more. One new consequence is that, given any non-degenerate linear function z, the number of local z-minima on the lth level of any d-dimensional arrangement is bounded by (l+d-1 / d-1) with exact equality if the l-th level is bounded and simple.
Cationic cyclocholamides; toroidal facial amphiphiles with potential for anion transport (2008)

Stabilising Rh–P coordination by phosphanylalkylcyclopentadienyl ligands (2003)

(Phosphanylalkyl/aryl)cyclopentadienyl complexes have been synthesised from lithiated 1,2,3,4-tetramethyl-5(2-P,P-dialkyl/arylphosphinoethyl)cyclopentadiene and [RhCl(CO)2]2; the electron donating properties of these ligands have been compared and the P–Rh interaction is shown to be stable under methanol carbonylation reaction conditions.
The curvature homogeneity bound for four-dimensional Lorentzian manifolds (2007)

We prove that a four-dimensional Lorentzian manifold that is curvature homogeneous of order 3, or $\\CH_3$ for short, is necessarily locally homogeneous. We also exhibit and classify four-dimensional Lorentzian, $\\CH_2$ manifolds that are not homogeneous. Our results imply that the Singer index for four-dimensional Lorentzian manifolds is greater or equal to 2.
Large-area YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-<i>x</i></sub>bolometers on Si substrates (1999)

We have developed YBa2Cu3O7-x (YBCO) thermometers for large-area (4 mm × 4 mm) electrical substitution bolometers. We passivated the YBCO with a thin Au layer and demonstrated a noise equivalent temperature of 4 nK Hz-1/2. We then used a resistor layer of NiCr alloy deposited directly on the thermometer to perform optical measurements of the bolometer in the cryostat. Optical measurements show an electrical noise equivalent power of 87 pW Hz-1/2 with a large thermal conductance of 1.87 × 10-3 W K-1. These thermometers may be used as a real-time measurement radiometer.
Photoelektrochemische Prozesse und Photokatalyse an Zinkoxid‐Suspensionen und Zinkoxid‐Deckschichten (1972)

Abstract Es wurden Photospannungen und Photoströme an ZnO‐Suspensionen im Kontakt mit Edelmetallelektroden sowie an ZnO‐Deckschichten auf metallischen Unterlagen untersucht. Die Deckschichten wurden durch Sinterung von ZnO‐Pulver oder durch anodische Oxidation von Zinkmetall hergestellt. Bei Bestrahlung mit UV‐Licht treten Photoströme und Photospannungen auf, die sich in Analogie zu Prozessen an ZnO‐Einkristallen deuten lassen. Die spektrale Abhängigkeit der Photoeffekte zeigt, daβ sich solche Schichten ähnlich wie amorphe Halbleiter verhalten. Entscheidend für das Reaktionsvermögen ist, wie bei den Einkristallen, die Erzeugung von Defektelektronen.
Integrated approach for smart implantable cardioverter defibrillator (ICD) device with real time ECG monitoring: use of flexible sensors for localized arrhythmia sensing and stimulation (2013)

Arrhythmias are the most common cause of death associated with sudden death and are common in US and worldwide. Cardiac resynchronization therapy (CRT), evolving from pacemakers and development of implantable cardioverter defibrillator (ICD), has been adopted for therapeutic use and demonstrated benefits in patients over the years due to its design and intricate functionality. Recent research has been focused on significant design improvement and efforts are dedicated toward device size reduction, weight and functionality in commercially available ICD's since its invention in the 1960's. Commercially available CRT-D has shown advancement on both clinical and technical side. However, improved focus is required on the device miniaturization, technologically supported and integrated wireless based system for real time heart monitoring electrocardiogram (ECG). In the present report a concise overview for the state-of-the art technology in ICDs and avenues for future development are presented. A unique perspective is also included for ICD device miniaturization and integration of flexible sensing array. Sensor array integration along with its capabilities for identifying localized arrhythmia detection and targeted stimulation for enhancing ICD device capabilities is reviewed.
A memory cell with single-electron and metal-oxide-semiconductor transistor integration (1999)

A single-electron transistor memory cell with metal-oxide-semiconductor field-effect transistor sensing has been fabricated in silicon-on-insulator material. The single-electron transistor, coupled to a memory node, is defined in the upper silicon layer. The memory node forms the gate of a metal-oxide-semiconductor field-effect transistor with its channel in the substrate silicon. At 4.2 K, there are two different states of the memory-node voltage, separated by the single-electron transistor Coulomb gap. These states are sensed at high-current output levels by the metal-oxide-semiconductor transistor. The metal-oxide-semiconductor transistor current also shows evidence of gate-dependent conductance oscillations in the coupled single-electron transistor.
Targeted disruption of mouse long-chain acyl-CoA dehydrogenase gene reveals crucial roles for fatty acid oxidation (1998)

Abnormalities of fatty acid metabolism are recognized to play a significant role in human disease, but the mechanisms remain poorly understood. Long-chain acyl-CoA dehydrogenase (LCAD) catalyzes the initial step in mitochondrial fatty acid oxidation (FAO). We produced a mouse model of LCAD deficiency with severely impaired FAO. Matings between LCAD +/− mice yielded an abnormally low number of LCAD +/− and −/− offspring, indicating frequent gestational loss. LCAD −/− mice that reached birth appeared normal, but had severely reduced fasting tolerance with hepatic and cardiac lipidosis, hypoglycemia, elevated serum free fatty acids, and nonketotic dicarboxylic aciduria. Approximately 10% of adult LCAD −/− males developed cardiomyopathy, and sudden death was observed in 4 of 75 LCAD −/− mice. These results demonstrate the crucial roles of mitochondrial FAO and LCAD in vivo .
No association between polymorphism in PEMT (V175M) and hepatic triglyceride content in the Dallas Heart Study (2006)

A nonsynonymous sequence variation (V175M) in PEMT, the gene encoding phosphatidylethanolamine N-methyltransferase, was recently reported in The FASEB Journal to be associated with nonalcoholic fatty liver disease (NAFLD) (1). The frequency of the 175M allele was significantly higher in 28 subjects with biopsy-confirmed NAFLD (23 Whites, 2 Blacks, 1 Hispanic, and 1 Asian) than in 59 subjects who had a normal hepatic triglyceride content (HTGC) by magnetic resonance imaging (MRI) (n=47) or by liver biopsy (n=12) (37 Whites, 14 Blacks, 3 Hispanics, 3 Asians, 1 Native American, and 1 Trinidadian, 67.9% vs. 40.7%; P<0.03). We analyzed the association between the V175M allele (~523 G>A) and hepatic triglyceride content (HTGC) in the Dallas Heart Study (DHS), a multiethnic population-based probability sample of Dallas County, Texas (2), in which ethnicity was self-reported. A total of 2349 Dallas Heart Study participants underwent proton magnetic resonance spectroscopy (1H-MRS) of the liver to quantify the HTGC after informed consent was obtained (3). Hepatic steatosis was defined as a HTGC exceeding the 95th percentile (HTGC>5.5%) when compared to healthy subjects with no evidence of hepatic disease (2). The alleles of the polymorphism were in Hardy Weinberg equilibrium (HWE) in all three ethnic groups (data not shown) and were not associated with HTGC or hepatic steatosis in any group, even after adjusting for BMI (Table 1). These data fail to support an association between the V175M allele and HTGC. 3.5 (2.2–6.2) 3.3 (2–6.1) 4.0 (2.4–8.3) 3.2 (1.8–5.4) 3.2 (1.9–5.1) 3.7 (2.2–6.7) 4.4 (2–10.6) 4.6 (2.8–10.9) 4.6 (3.1–13.4) 3.2 (2.7–3.9) 3.2 (2.5–4.4) 3.5 (2.6–5.0) 2.8 (2.4–3.8) 3.0 (2.5–3.8) 3.0 (2.5–3.8) 4.6 (3.8–6.2) 4.8 (3.7–6.4) 4.9 (3.6–6.2)

Analysis of Grain Production in Rice Plant. : I. Influence of nitrogen levels on light receiving coefficient and respiration rate. : II. Influence of nitrogen levels on light receiving coefficient and dry matter production. (1957)

Paddy rice plent, the variety Norin No. 29 were grown under various nitrogen conditions and several aspects concerning the dry matter production were observed. From the experimental results following conclusion was derived. The relationships between dry matter productivity and the factors constituting CO2 Assimilation ability of rice plants growing under community conditions and respiration have studied. In general, the dry matter productivity of the rice community can be expressed as follows : ΔW=k·L·S·p0-Rw (k=constant) where, ΔW denotes the dry matter produced per day, L, integrated intesety, S leaf area, p0, mean photosynthetic activity per leaf area under saturating light intensity, ρ, light-receiving coefficient, Rw, consumed dry matter by respiration.
Computational Modeling of the Seismic Performance of Beam-Column Subassemblies (2011)

Analytical studies are carried out to investigate the effectiveness of finite element modeling procedures in accurately capturing the nonlinear cyclic response of beam-column subassemblies. The analyses are performed using program VecTor2, employing only default or typical material constitutive models and behavior mechanisms in order to assess analysis capabilities without the need for special modeling techniques or program modifications. The specimens considered cover a wide range of conditions, and include interior and exterior seismically and non seismically designed beam-column subassemblies. It is shown that finite element analyses can achieve good accuracy in determining the strength, deformation response, energy dissipation, and failure mode of reinforced concrete beam-column subassemblies under seismic loading conditions.
Beiträge zur Konstitutionsaufklärung des Nocadamins. 10. Mitteilung über antibakterielle Stoffe (1951)

Abstract Bei der Hydrolyse von Nocardamin (C 9 H 14 O 3 N 2 , Smp. 184°), einem Antibiotikum aus einer Nocardia‐Art (Actinomycetaceae Buchanan), mit wässeriger Halogenwasserstoffsäure entsteht Bernsteinsäure und das Salz eines halogenhaltigen basischen Spaltstückes, C 5 H 13 ON 2 Hal, HHal. Dieses enthält eine primäre Amino‐ und wahrscheinlich eine Hydroxylamingruppe, mit denen die beiden Carboxylgruppen der Bernsteinsäure säureamidartig verknüpft sind. Durch Reduktion wird das basische Spaltstück der sauren Hydrolyse in Cadaverin übergeführt. Die von uns für Nocardamin ins Auge gefasste Konstitutionsformel Ia trägt diesen Befunden und den Ergebnissen verschiedener chemischer Umsetzungen, die mit dem basischen Spaltstück durchgeführt wurden, Rechnung. Nocardamin wäre auf Grund dieser Formulierung durch einen Trimethyleniminring (Azetidinring) und durch eine Hydroxylamingruppierung besonders gekennzeichnet. Der Azetidinring wäre damit u. W. in einem Naturprodukt erstmals aufgefunden worden. Über die endgültige Aufklärung der Struktur des Nocardamins hoffen wir später berichten zu können.
Electronic states and total energies in hydrogenated amorphous silicon (1982)

The effects of bulklike and surfacelike surroundings on the electronic density of states of a variety of Si-H bonding conformations in hydrogenated amorphous silicon are examined using the cluster Bethe-lattice approach. Firstly, we discover that two fundamentally different bonding patterns, with different consequences for the doping mechanism, are consistent with ultraviolet photoemission spectroscopy (UPS) data. These are (1) H atoms bonded in microcrystalline regions and (2) clusters of monohydrides (SiH) in a continuous random network. Our results suggest an experiment in which x-ray photoemission spectroscopy and UPS taken together should distinguish between (1) and (2) and hence contribute toward understanding doping. Secondly, by using the calculated densities of states, the energies of a number of conformations and dehydrogenation reactions are calculated with the use of an empirical bond-strength total-energy scheme. Our results agree with results from annealing experiments. We introduce an improvement in the Bethe-lattice method which permits efficient solution of a second-neighbor tight-binding Hamiltonian, and which is valid for $N\mathrm{th}$-neighbor interactions. We also estimate the Hubbard $U$, Stokes shifts, and electronic states associated with neutral and charged dangling bonds.
Generation and release of nitrotyrosine <i>O</i>-sulfate by HepG2 human hepatoma cells upon SIN-1 stimulation: identification of SULT1A3 as the enzyme responsible (2006)

In addition to serving as a biomarker of oxidative/nitrative stress, elevated levels of nitrotyrosine have been shown to cause DNA damage or trigger apoptosis. Whether the body is equipped with mechanisms for protecting against the potentially harmful nitrotyrosine remains unknown. The present study was designed to investigate the possibility that sulfation serves as a pathway for the metabolism/regulation of nitrotyrosine. Using metabolic labelling, nitrotyrosine O-[35S]sulfate was found to be produced and released into the medium of HepG2 human hepatoma cells labelled with [35S]sulfate in the presence of nitrotyrosine. To identify the enzyme(s) responsible for nitrotyrosine sulfation, a systematic study of all eleven known human cytosolic SULTs (sulfotransferases) was performed. Of the 11 enzymes tested, only SULT1A3 displayed sulfating activity toward nitrotyrosine. The pH-dependence and kinetic constants of SULT1A3 with nitrotyrosine or dopamine as substrate were determined. To examine whether the sulfation of nitrotyrosine occurs in the context of cellular physiology, HepG2 cells labelled with [35S]sulfate were treated with SIN-1 (morpholinosydnonimine), a peroxynitrite generator. Increments of nitrotyrosine O-[35S]sulfate were detected in the medium of HepG2 cells treated with higher concentrations of SIN-1. To gain insight into the physiological relevance of nitrotyrosine sulfation, a time-course study was performed using [3H]tyrosine-labelled HepG2 cells treated with SIN-1. The findings confirm that the bulk of free [3H]nitrotyrosine inside the cells was present in the unconjugated form. The proportion of sulfated [3H]nitrotyrosine increased dramatically in the medium over time, implying that sulfation may play a significant role in the metabolism of free nitrotyrosine.
