Extra-Large-Pore Zeolites with Two-Dimensional Channels Formed by 14 and 12 Rings (2004)

Stable zeolites that have larger pore apertures and a three-dimensional pore topology are of interest because they could be used to adsorb larger molecules, particularly for application in oil refining. Several large-pore zeolitic materials with channels formed by openings of more than 12 rings are known, but all of them have a one-dimensional channel system that limits their use in catalysis. We report the synthesis and some characterizations of IM-12, a thermally stable germanium-containing zeolite that contains the first two-dimensional channel system with extra-large pores formed by 14- and 12-ring channels.
Comprehensive Phenotype of the p.Arg420his Allelic Form of Spinocerebellar Ataxia Type 13 (2013)

The p.Arg420His allelic form of spinocerebellar ataxia type 13 has been reported in a large Filipino kindred, as well as three European index cases, one with an affected offspring. Haplotype analysis has confirmed independent mutational events. All individuals share adult-onset, predominantly cerebellar signs and a slowly progressive course. However, a comprehensive phenotypic description has yet to be published on SCA13(p.Arg420His). In this study, we present the results of a detailed neurological clinical and diagnostic testing on 21 mutation-positive members of a four-generation Filipino family to further define this disease, aiding diagnosis and prognosis.
Wie können Tunten Sozialisten sein? (1975)

An den Vorstellungen dessen, was eine „Tunte" ist, sind die anti-homosexuellen Vorurteile der „Hetero-" wie der „Homosexuellen" auf ihren Begriff gebracht. Die ,,Vorurteile und Unwissenheit" der „Kommunisten und Sozialisten in Deutschland" (es fehlen in dieser Aufzählung Demokraten und Christen) sind aber in dem Artikel von „Thorsten Grar' und „Mimi Steglitz" vermutlich kaum angegriffen worden (l). Das erstens aus noch anzugebenden Gründen, die das Verhältnis von Sein und Bewußtsein, insbesondere den „Ursprungsort" verkehrter Bewußtseinsformen, betreffen. In diesem Zusammenhang wäre die Frage nach der politischen Bestimmung des Verhältnisses homosexueller Emanzipationsgruppen zu den Organisationen der Lohnarbeiter, vor allem der Gewerkschaften, schon im Ansatz sehr viel präziser zu diskutieren gewesen. Zweitens aus dem Grund der pseudonymen Veröffentlichung. Deshalb kann übrigens der Artikel von der Redaktionskonferenz der PROKLA nicht diskutiert worden sein (la). Eine pseudonyme Veröffentlichung ist problematisch, wenn der Schutz des Pseudonyms verlangt wird, weil die Autoren in der PROKLA veröffentlichen. Die Verfasser fürchteten kein „eventuelles Berufsverbot für Schwule", sondern das „Berufsverbot für ,Radikale' im öffentlichen Dienst" (2). Wer sagt hier was? Die Verinnerlichung dieser Fremdeinschätzung von PROKLA-Autoren denunziert sie aufgrund einer Identifikation mit einem Aggressor, den sich die Autoren für sich vorstellen können, dem sie sich aber als Sozialisten nicht beugen dürften. Die politische Begründung des Pseudonyms hat etwas mit Homosexualität zu tun, weil das Problem der Entwicklung des Selbstbewußtseins von Homosexuellen doch gerade darin besteht, das Bewußtwerden homosexueller Wünsche von dem Muster der Identifikation solchen Verlangens mit einem Aggressor oder Agressionen zu lösen, um so die Verselbständigung des isolierten Motivs der Homosexualität im Bewußtsein der Homosexuellen selber, ihre Borniertheit also, aufheben zu können. Das verdrängte homosexuelle Verlangen bedarf einer kontrollierenden Instanz, die über die Identifikation mit einem Aggressor die Aufrechterhaltung der Verdrängung garantiert.
Fast, automatic, and accurate catheter reconstruction in HDR brachytherapy using an electromagnetic 3D tracking system (2015)

The EM reconstruction was found to be more accurate and precise than the conventional methods used for catheter reconstruction in HDR-B. This approach can be applied to any type of catheters and applicators.
Planar InGaAs/InP photodiodes grown by metalorganic chemical vapor deposition (1985)

Planar InGaAs/InP heterostructure photodiodes have been fabricated from structures grown by atmospheric pressure metalorganic chemical vapor deposition. Diffused p-n junction devices of 75µm diameter have low dark currents (∼20nA at -10V), good quantum efficiencies of ∼50% (without AR coatings), and very high speed response (∼35ps).
Die Passionsgeschichte bei Matthus (1955)

Die Leidensgeschichte bei Matthus ist ein geeigneter Ausgangspunkt fr eine Diskussion ber synoptische Fragen und Probleme der Evangelienforschung. Das ist sie zunchst deshalb, weil das literarkritische Verhltnis hier besonders klar zu Tage liegt. Die Matthus-Passion steht der Markus-Passion sehr nahe. Alle Episoden des Markus-Berichtes finden sich auch bei Matthus, es fehlen nur ein paar kurze Notizen (Mark. xiv. 51 f.; xv. 21 b ) und dazu einige ausmalende Einzelheiten (Mark. xiv. 34, 7, 1215, 40, 569, 67; xv. 7, 445; xvi. 15) Noch bemerkenswerter ist, da die Ordnung und Reihenfolge innerhalb der Passionsgeschichte bei Matthus und Markus ohne Ausnahme dieselbe ist. In groem Umfange finden sich wrtliche oder beinahe wrtliche bereinstimmungen. Ein Vergleich mit Lukas und Johannes lt sofort erkennen, wie nahe Matthus and Markus zusammengehren. Bei ihnen liegen zwei Varianten eines and desselben Berichtes vor.
Implementation of a Mobile Platform Based on Fiber Bragg Grating Sensors for Automotive Traffic Monitoring (2020)

Instrumentation techniques, implementation and installation methods are major concerns in today's distributed and quasi-distributed monitoring applications using fiber optic sensors. Although many successful traffic monitoring experiments have been reported using Fiber Bragg Gratings (FBGs), there has been no standardized solution proposed so far to have FBG seamlessly implemented in roads. In this work, we investigate a mobile platform including FBG sensors that can be positioned on roads for the purpose of vehicle speed measurements. The experimental results prove the efficiency of the proposed platform, providing a perspective toward weigh-in-motion systems.
Mapping Putative B-Cell Zika Virus NS1 Epitopes Provides Molecular Basis for Anti-NS1 Antibody Discrimination between Zika and Dengue Viruses (2017)

B-cell epitope sequences from Zika virus (ZIKV) NS1 protein have been identified using epitope prediction tools. Mapping these sequences onto the NS1 surface reveals two major conformational epitopes and a single linear one. Despite an overall average sequence identity of ca. 55% between the NS1 from ZIKV and the four dengue virus (DENV) serotypes, epitope sequences were found to be highly conserved. Nevertheless, nonconserved epitope-flanking residues are responsible for a dramatically divergent electrostatic surface potential on the epitope regions of ZIKV and DENV2 serotypes. These findings suggest that strategies for differential diagnostics on the basis of short linear NS1 sequences are likely to fail due to immunological cross-reactions. Overall, results provide the molecular basis of differential discrimination between Zika and DENVs by NS1 monoclonal antibodies.
Techniques to minimize <i>DX</i> center deleterious effects in III-V device performance (1993)

The properties of deep donor states (DX centers) in III-V alloys are discussed in relation to their influence on device characteristics and performance. The techniques to avoid or minimize such deleterious effects in AlGaAs-based devices are discussed, along with their physical basis, and some guidelines for improved III-V device design are established. New results about the benefits of proper donor selection, the role of In alloying, the advantage of δ doping in layers and in modulation-doped devices, and the use of AlInAs and InGaP as alternative wide band-gap III-V alloys are presented.
Fast volume rendering using adaptive block subdivision (2002)

We propose a fast volume rendering scheme that greatly reduces ray-casting overheads by adaptive block subdivision. We first apply a uniform space subdivision for constructing the adaptively subdivided volume. Then we merge coherent uniform blocks to generate adaptive-sized blocks that are efficient for leaping space. To accomplish this, an efficient block merging algorithm based on a boundary following and scan-filling strategy is proposed. Experimental results show that our fast volume rendering scheme is superior to other schemes in constructing a data structure for fast rendering; due to its simple construction approach, construction speed is more than three times faster than a hierarchical data structure, the octree. A 25% to 70% performance gain in rendering time over the octree is also exhibited. The additional advantages of our scheme are a stable acceleration for animation and an associativity with a compression-based volume rendering.
Enzyme-Catalyzed Polymerizations of ε-Caprolactone:  Effects of Initiator on Product Structure, Propagation Kinetics, and Mechanism (1996)

Studies were undertaken to gain mechanistic information on lactone ring-opening polymerization reactions using porcine pancreatic lipase (PPL) as the catalyst and ε-caprolactone (ε-CL) as the monomer. Polymerizations were carried out at low water levels (0.13 mmol) and supplemented with either butanol or butylamine. Rates of monomer conversion, product molecular weight, total chain number, and chain end structure were determined by 1H NMR. In the presence of water alone, a maximum Mn of 7600 g/mol was obtained at 85% conversion, which decreased to 4200 g/mol as the reaction continued to 98% conversion. Reactions with butanol and butylamine at 100% conversion gave polymers with Mn values of 1900 and 1200 g/mol, respectively. For these three polymerizations, the total number of polymer chains increased with conversion due to a simultaneous increase in carboxylic acid chain ends. Within 4 h (∼26% monomer conversion), butylamine was completely consumed but only 37% of butanol reacted. Reactions with butylamine occurred predominantly by an enzyme-mediated route to form N-butyl-6-hydroxyhexanamide. This step was rapid relative to subsequent chain growth. In addition, the living or immortal nature of the polymerizations was assessed from plots of log{[M]0/[M]t} versus time and Mn versus conversion. These results indicate that termination and chain transfer did not occur, and we described the system as providing “controlled” polymerizations. Furthermore, an expression for the rate of propagation was derived from the experimental data which is consistent with that derived from the proposed enzyme-catalyzed polymerization mechanism. The absence of termination in conjunction with the relationship between molecular weight and the total concentration of multiple initiators suggests that ε-CL polymerization by PPL catalysis shares many features of immortal polymerizations.
APPLICATION, ECONOMICS AND CHOICE OF RADIATION SOURCES (1961)

In regard to the main field of applications of high-energy radiations (chemistry, biology, pharmaceutics, and food industrues), the properties of radiation sources available today are subjected to closer examination from a technical and economic standpoint. Electron accelerators, highpower x-ray equipment, and Co/sup 60/ sources of different capacity are discussed in detail whereas the remaining radiation sources, such as fission products, spent fuel elements, and reactors are only briefly mentioned. lt is also shown that the choice of a radiation source must not be based on merely economtc but on technical considerations also (auth)
Operability and Efficiency Performance of Ultra-Compact, High Gravity (g) Combustor Concepts (2006)

Future gas turbine engines are required to be more capable than their predecessors. This often implies severe demands on the engine that translate into increasing compressor and combustor exit temperatures, higher combustion pressures and higher fuel/air ratio combustors with greater turn-down ratios (wider operating limits between idle and maximum power conditions). Major advances in combustor technology are required to meet the conflicting challenges of improving performance, increasing durability and maintaining cost. Unconventional combustor configurations are one promising approach to address these challenges. Ultra-short combustors to minimize residence time, with special flame-holding mechanisms to cope with increased through-velocities are likely in the future. Engine cycles other than the standard Brayton cycle may also be used for special applications in order to avoid the use of excessive combustion temperatures, and to extract additional power from the system. This paper focuses on vortex-stabilized combustor technologies that can enable the design of compact, high-performance combustion systems. Compact combustors weigh less and take up less volume in space-limited turbine engine for aero applications. This paper presents a parametric design study of the Ultra-Compact Combustor (UCC), a novel design based on TVC work that uses high swirl in a circumferential cavity to enhance reaction rates via high cavity g-loading on the order of 3000 g’s. Increase in reaction rates translates to a reduced combustor volume. Three combustor geometric features were varied during experiments which included (1) high-g cavity flame-holding method, (2) high-g cavity to main airflow transport method, and (3) fuel injection method. Experimental results are presented for these combustor configurations and results have shown promise for advanced engine applications. Lean blowout fuel-air ratio limits at 25–50% the value of current systems were demonstrated. Combustion efficiency was measured over a wide range of UCC operating conditions. This data begins to build the design space required for future engine designs that may use these novel, compact, high-g combustion systems.
Optimization of the Synthesis of Nanostructured Tungsten-Molybdenum Bimetallic Oxide (2012)

nanoparticles were prepared through the Pechini process and were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), FT-IR spectrometer, and differential thermal analysis (TG-DSC) analyses. The polyesterification reaction, as the starting step, has a profound influence on the dispersion of the resulting nanoparticles. The molar ratios CA : TM = 2 and EG : CA = 1.5 are favorable for the preparation of nanoparticles having average particles size ranging from 2 to 9 nm. Meanwhile, the molar ratios CA : TM = 4 and EG : CA = 0.19 are favorable for the preparation of nanoparticles having an average particles size ranging from 11 to 29 nm. For the calcination step, increased calcination time (eight hours) at 500°C is advantageous for allowing the monometallic phases enough time to transform into the desired bimetallic phase.
APPROACHES TO BRAIN TUMORS IN CHILDREN (1999)

BACKGROUND- Over the course of a career, the neurologist and child neurologist will diagnose and participate in treating at least several children with brain tumors. The proliferation of neuro-oncology centers in larger medical centers lends to the referral of patients to those centers, sometimes a distance from home, where patients can receive state-of-the-art care. However, there continues to be a role for the non-subspecialist neurologist in caring for children with brain tumors, both during and after therapy is completed. The families will often look to a neurologist who does not have an affiliation with the larger medical centers for an opinion regarding treatment options. During treatment, the neurologist will often monitor anticonvulsant therapy; after treatment, the community neurologist will often provide care to that child for many years. REVIEW SUMMARY- New surgical techniques have made aggressive attempts at tumor removal safer than in the past. In some instances, less invasive surgical approaches will result in the same result, without the need for a craniotomy or ventriculoperitoneal shunt. Improvements in radiotherapy techniques will allow for increasingly conformal approaches to treating only the volume of tumor and brain intended, which will hopefully result in less cognitive toxicity. New medications for treating the most common malignant brain tumor in children, the medulloblastoma, have resulted in greatly improved survival and will allow for the radiotherapy close to be reduced to a more tolerable close. Aggressive approaches to delivering high-dose chemotherapy are still controversial, but the initial data in infants suggest that cognitive function is spared if radiotherapy can be delayed, although there is significant early treatment toxicity, as well as delayed second malignancies. CONCLUSION- There have been a number of advances in caring for children with brain tumors. Complete surgical excision without complication remains the major problem encountered for the child a low-grade neoplasm. For most high-grade tumors, disease control without unacceptable toxicity remains the goal for the future. In this article, I review recent advances in terms of pathogenesis and new concepts in pathology, as well as advances in brain tumor management.
Anwendung polarographischer O<sub>2</sub>‐Messungen auf die Veratmung von <i>n</i>‐Alkanen und deren Derivaten durch <i>Acinetobacter calcoaceticus</i> (1977)

Abstract Mit Hilfe einer polarographischen O 2 ‐Meßanordnung im geschlossenen System wurde die Fähigkeit von nicht‐wachsenden Zellen von Ac. calcoaceticus für die Veratmung von n ‐Alkanen und deren Derivaten untersucht. Die Bakterien waren auf Hexadecan kultiviert, in der logarithmischen Phase geerntet und 2 Std. lang zur Substratverarmung in C‐freiem Medium inkubiert worden. Die initialen Atmungsraten mit n ‐Alkanen als Substrat sinken vom Ende der log‐Phase an kontinuierlich ab. Mit steigender Tetradecan‐Konzentration folgen die Atmungsraten Sättigungskurven (bis etwa 2 · 10 −5 M), bei weiterer Erhöhung gibt es es ein Minimum (bei etwa 10 −4 M) und dann wieder einen erneuten Anstieg ohne erkennbare Sättigung. Bis zum Ende der Oxydation werden pro Mol Tetradecan etwa 10 Mol O 2 verbraucht; das entspricht einer Oxydation über das Acetat hinaus, aber nicht bis zu Kohlendioxid/Wasser. Die Atmungsraten steigen bei gleichen molaren Konzentrationen mit der Kettenlänge der Alkane an, und zwar stärker als es dem erhöhtem O 2 ‐Bedarf, der durch die Kettenverlängerung bedingt ist, entspricht. Es werden auch mittelkettige n ‐Alkane (bis herunter zum Hexan) veratmet, obwohl diese nicht als C‐Quelle genutzt werden können. Derivate der n ‐Alkane werden ebenfalls veratmet, nur l,ω‐Dibrom‐Alkane werden nicht umgesetzt. Für die Alkane sowie für die meisten der Derivate wird die Fähigkeit zur Oxydation durch Kultivierung auf n ‐Alkanen erst induziert. Alkanole und Alkanone können in geringerem Umfange allerdings auch nach Wachstum auf Acetat veratmet werden. Die Oxydation der Alkansäuren ist konstitutiv.
Correlating the Radiation Response of MOS Capacitors and Transistors (1984)

A new technique is presented for separating the threshold-voltage shift of an MOS transistor into shifts due to interface states and trapped-oxide charge. Using this technique, the radiation responses of MOS capacitors and transistors fabricated on the same wafer are compared. A good correlation is observed between p-substrate capacitors and n-channel transistors irradiated at 10 V, as well as between n-substrate capacitors and p-channel transistors irradiated at 0 V. These correlations were verified for samples having large variations in the amount of radiation-induced trapped holes and interface states. An excellent correlation is also observed between n-channel capacitors and n-substrate transistors irradiated under positive bias. The use of capacitors separately fabricated on control wafers for potential use in process development or monitoring is clearly demonstrated.

Thermal-wave transient behaviour (1986)

When a thermal wave is switched on, it takes some time until phase and magnitude have reached their final values. Numerical calculations are presented for the transient behaviour when a sinusoidal or square-wave temperature modulation is applied to the surface of a homogenous semi-infinite solid. The influence of sample depth, time, and modulation form is discussed.
Design and Evaluation of an Architecture for Ubiquitous User Authentication Based on Identity Management Systems (2011)

Nowadays, users consume digital services with their digital identities on a multitude of different devices, e.g. notebooks, smartphones or even TV sets. Hereby, users are faced with additional challenges, i.e., devices have different security levels and not all digital identities must be used on all devices. Identities used for home banking should not be used on an insecure device and business identities should only be used on business devices. Moreover, it should be possible to switch between devices in a seamless way without the need to reauthenticate again on each device. Therefore, we propose an architecture that integrates all user devices and exploits identity management systems for ubiquitous user authentication. The proposed architecture improves usability by reducing the number of manual authentication procedures, by relaying authentication to devices with appropriate input capabilities and by supporting the user in identity selection. Security is improved by the possibility to perform authentication on secure devices, the provisioning of short-lived tokens to in secure devices and the opportunity to perform multifactor authentication across devices. Our implementation is based on the Shibboleth IdM system and serves as proof-of-concept of our architecture. The conducted security evaluation confirms that our concept does not introduce additional security threats.
