Enantioselektive Protonierung von Enolaten und Enolen (1996)

Abstract Enantioselektive Protonierung, eine bis vor kurzem im großen und ganzen übersehene Reaktion, hat sich in den letzten fünf Jahren zu einem Forschungsgebiet mit intensiven Aktivitäten entwickelt. Der erreichte Fortschritt ergänzt und erweitert jenen, der beim Verständnis von Enolatstrukturen und ‐reaktivitäten erzielt worden ist. Die konzeptionelle Einfachheit und Attraktivität enantioselektiver Protonierungen ergeben sich aus der Tatsache, daß der chirale Protonendonor durch eine extraktive Aufarbeitung in seiner ursprünglichen protonierten Form wiedergewonnen wird. Enantioselektive Protonierungen wurden zur Synthese von Aminosäuren, entzündungshemmenden Verbindungen (2‐Arylpropionsäuren) und auch von Duftstoffen wie dem auch industriell auf diesem Weg zugänglichen ( S )‐α‐Damascon angewendet.

Experimental Detection and Reception Performance for Uplink Underwater Acoustic Communication Using a Remote, In-Air, Acousto-Optic Sensor (2006)

Covert communications between underwater and aerial platforms would increase the flexibility of surface and air vehicles engaged in undersea warfare by providing a new netcentric warfare communications capability and could have a variety of commercial and oceanographic applications. Research into an acousto-optic sensor shows promise as a means for detecting acoustic data projected toward the water surface from a submerged platform. The laser-based sensor probes the water surface to detect perturbations caused by an impinging acoustic pressure field. Experimental studies were conducted to demonstrate acousto-optic sensor feasibility for obtaining accurate phase preserved recordings of communication signals across the air-water interface. The recorded surface velocity signals were transferred to an acoustic communications receiver that used conventional acoustic telemetry algorithms such as adaptive equalization to decode the signal. The detected, equalized, and decoded bit error rate performance is presented for hydrostatic and more realistic, hydrodynamic water surface conditions
Secreted Euryarchaeal Microhalocins Kill Hyperthermophilic Crenarchaea (2001)

Few antibiotics targeting members of the archaeal domain are currently available for genetic studies. Since bacterial antibiotics are frequently directed against competing and related organisms, archaea by analogy might produce effective antiarchaeal antibiotics. Peptide antibiotic (halocin) preparations from euryarchaeal halophilic strains S8a, GN101, and TuA4 were found to be toxic for members of the hyperthermophilic crenarchaeal genus Sulfolobus. No toxicity was evident against representative bacteria or eukarya. Halocin S8 (strain S8a) and halocin R1 (strain GN101) preparations were cytostatic, while halocin A4 (strain TuA4) preparations were cytocidal. Subsequent studies focused on the use of halocin A4 preparations and Sulfolobus solfataricus. Strain TuA4 cell lysates were not toxic for S. solfataricus, and protease (but not nuclease) treatment of the halocin A4 preparation inactivated toxicity, indicating that the A4 toxic factor must be a secreted protein. Potassium chloride supplementation of the Sulfolobus assay medium potentiated toxicity, implicating use of a salt-dependent mechanism. The utility of halocin A4 preparations for genetic manipulation of S. solfataricus was assessed through the isolation of UV-induced resistant mutants. The mutants exhibited stable phenotypes and were placed into distinct classes based on their levels of resistance.
Effect of process mixing on the size distribution and mean diameter of the thiol-triacrylate microcapsules (2014)

An important limitation in the development of the microparticles is the difficulty to develop a precise size distribution. Microparticles have a wide spread applicability in different fields including medical, pharmaceutical, textile, cosmetics, pesticide, printing industry, etc. The large and growing impact of microencapsulation in different fields of technology has made this process important. Microparticle size is a primary determinant of control release mechanism and the reaction kinetics and also impacts the allowable routes of administration, The main objective of this research work is to evaluate the effect of the process mixing on the size and size distribution of the trithiol-triacrylate microparticles prepared via dispersion polymerization using the primary amine catalyzed addition of trithiol to triacrylate. The influence of several synthesis parameters such as, the stirring rate, oscillation frequency and amplitude, surfactant concentration in the aqueous phase on the size distribution of the microparticles has been investigated. A comparison between the reactor with three blades propeller and oscillatory reactor in terms of particle size distribution and energy dissipation per unit mass has been reported. A laboratory investigation has been performed to identify the most suitable reactor based on the desired size distribution of the micropartcles. The experimental results indicate that oscillatory reactor is more suitable to achieve small particle size and narrow size distribution.
Microwave Acoustic Devices for Pulse Compression Filters (1969)

The ability of devices based on the phenomena of magnetoelastic waves, acoustic bulk waves, acoustic surface waves, and the optoacoustic interaction to fulfill the requirements for a dispersive filter for a pulse compression RADAR are reviewed. The performance and current limitations of devices that use techniques employing these effects are described. The discussion is generally limited to devices which have been operated in the frequency range above 100 MHz. For comparison, other solid-state techniques that do not employ acoustic waves which can be used to make dispersive filter are described.

Population and pedigree studies reveal a lack of association between the dopamine D2 receptor gene and alcoholism (1990)

Using the dopamine D<sub>2</sub>receptor clone λhD2G1, Blum et al recently found that the D<sub>2</sub>/<i>Taq</i>I allele (A1) was present in 69% of 35 deceased alcoholics but in only 20% of an equal number of controls. To assess this association further, we evaluated the D<sub>2</sub>/Taq I polymorphism and a single-strand conformation polymorphism detected by polymerase chain reaction and nondenaturing gel electrophoresis (PCR-SSCP) of the 3' noncoding region of the D<sub>2</sub>receptor gene. We studied 40 unrelated white alcoholics, 127 racially matched controls, and two white pedigrees. The Schedule for Affective Disorders and Schizophrenia—Lifetime Version (SADS-L) clinical diagnostic interviews were rated blindly by two clinicians. The SADS-L interviews and other data were then used to ascertain diagnoses according to the<i>Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition (DSM-III-R)</i>criteria. Alcoholics were subtyped according to age of onset, severity, presence of antisocial personality, and family history. No significant differences in either D<sub>2</sub>/<i>Taq</i>I or PCR-SSCP allele frequencies were observed between alcoholics, subpopulations of alcoholics, or controls. The PCR-SSCP polymorphism provided independent information against linkage at the D<sub>2</sub>receptor locus. Several recombinants between the D<sub>2</sub>/<i>Taq</i>I locus and alcoholism were observed in two white families with an alcoholic parent who possessed the A1 allele. This study does not support a widespread or consistent association between the D<sub>2</sub>receptor gene and alcoholism. (<i>JAMA</i>. 1990;264:3156-3160)
Model calculations of superlubricity of graphite (2004)

In this paper, friction between a finite, nanometer-sized, rigid graphite flake and a rigid graphite surface is analyzed theoretically in the framework of a modified Tomlinson model. Lateral forces are studied as a function of orientational misfit between flake and surface lattices, pulling direction of the flake, flake size and flake shape. The calculations show that the orientation dependence of the friction provides information on the contact size and shape. We find good agreement between the calculations and the experimental results, discussed in a recent publication by Dienwiebel et al. [M. Dienwiebel, G. S. Verhoeven, N. Pradeep, J. W. M. Frenken, J. A. Heimberg, and H. W. Zandbergen, Phys. Rev. Lett. 92, 126101 (2004)].
[Superficial temporal artery-middle cerebral artery anastomosis in a patient of temporal arteritis with internal carotid artery occlusion: a case report]. (2012)

Temporal arteritis is a rare systemic autoimmune disease and the arteritic process in this case of temporal arteritis involved large and medium-size arteries. Temporal arteritis with internal carotid artery (ICA) occlusion is very rare. We report a case of temporal arteritis with ICA occlusion following superficial temporal artery (STA) -middle cerebral artery (MCA) anastomosis, together with steroid therapy. A 73-year-old female presented with a headache, visual disturbance of left side, and suppression of activity. Left STA was inflammatory and overswelling. Magnetic resonance angiography (MRA) and angiography revealed occlusion of the left internal carotid artery (ICA) at the cervical portion and lowering of vascular reserve on PAO SPECT. Diagnosis as temporal arteritis was conclusive due to the clinical presentation, laboratory studies, and left temporal artery biopsy, so steroid pulse therapy was initiated. Inflammation of left STA disappeared after steroid therapy, but left ICA occlusion on angiography and lowering of vascular reserve on SPECT remained for 3 months afterwards. Because of this, STA-MCA anastomosis was performed. There were no complications after the operation and the donor artery has been patent for two years. Temporal arteritis with ICA occlusion that requires extracranial-intracranial bypass (EC-IC bypass) is very rare. STA-MCA anastomosis with steroid therapy is effective for the prevention of cerebral infarction.
A Tensor‐based Measure for Estimating Blood Damage (2004)

Implantable ventricular assist devices give hope of a permanent clinical solution to heart failure. These devices, both pulsatile- and continuous-flow, are presently used as medium-term bridge to heart transplant or recovery. While long-term use of continuous-flow axial and centrifugal pumps is being explored, the excessive level of blood damage in these devices has emerged as a design challenge. Blood damage depends both on shear stress and exposure time, and device designers have relied traditionally on global space- and time-averaged estimates from experimental studies to make design decisions. Measuring distributions of shear stress levels and the blood cell's exposure to these conditions in complex rotary pump flow is difficult. On the other hand, computational fluid dynamics (CFD) is now being used as a tool for designing viable devices, offering more detailed information about the flow field. A tensor-based blood damage model for CFD analysis is proposed here. The model estimates the time- and space-dependent strain experienced by individual blood cells and correlates it to blood damage data from steady shear flow experiments. The blood cells are modeled as deforming droplets and their deformation is tracked along the pathlines of a computed flow. The model predicts that blood cells in a rapidly fluctuating shear flow can sustain high shear stress levels for very short exposure time without deforming considerably. In the context of mechanical modeling of the implantable Gyro blood pump being developed at Baylor College of Medicine, this suggests that blood cells traversing regions of highly fluctuating shear stress rapidly may not hemolyze significantly.
Biometrics-based Data Link Layer Anonymous Authentication in VANETs (2013)

The vehicular ad-hoc network (VANET) aims to make road traffic safer and more efficient. Security and privacy are two important but somewhat contradictory objectives. On the one hand, vehicle-to-vehicle (V2V) authentication requires drivers to present some individual credentials. On the other hand, drivers need privacy protections on their identities, physical locations, and other contextual information. No sensitive information should be unnecessarily exposed during the authentication phase. Therefore, anonymous authentication is expected to play a critical role in VANET. In this paper, we propose a novel biometrics-based anonymous mutual authentication with provable link-layer location privacy preservation. During its authentication phase, two vehicles negotiate their temporary session key and generate two temporary MAC addresses. These two addresses, instead of the real ones, are used in all future communication frames. We further protect the biometric privacy with the help of a biometric encryption technique. Our analysis and simulation results show that the protocol is superior and lightweight with strong security and privacy protection.
Multi-Criteria Decision Making Based Logistics Brokerage Agents (2003)

In this paper we deal with the logistics brokerage process in which a logistics agent intermediates between vehicle owners and shippers for matching empty vehicles and freights. Based on the Multi-Criteria Decision Making (MCDM) methodology, the proposed agent system matches the most preferred empty vehicle to the shipper and the most preferred freight to the vehicle owner. In the proposed agent system, an MCDM based sensitivity analysis is also used for supporting decision makers under negotiations. Among various MCDM methodologies, Analytic Hierarchy Process (AHP) is utilized in this paper. Although AHP is one of the most popular MCDM methodologies, AHP needs a number of pair-wise comparisons for assessing alternatives and hence may give excessive decision making burden to the decision makers. In this paper, in order to reduce the decision making burden, a preference function based estimation method is proposed. We can expect that the MCDM based logistics brokerage agent can be used as an efficient and effective tool for e-logistics marketplaces on the internet.
Visage: a user interface environment for exploring information (2002)

Visage is a prototype user interface environment for exploring and analyzing information. It represents an approach to coordinating multiple visualizations, analysis and presentation tools in data-intensive domains. Visage is based on an information-centric approach to user interface design which strives to eliminate impediments to direct user access to information objects across applications and visualizations. Visage consists of a set of data manipulation operations, an intelligent system for generating a wide variety of data visualizations (SAGE) and a briefing tool that supports the conversion of visual displays used during exploration into interactive presentation slides. This paper presents the user interface components and styles of interaction that are central to Visage's information-centric approach.
Safety and Efficacy of Glycerol and Amino Acids in Combination With Lipid Emulsion for Peripheral Parenteral Nutrition Support (1992)

The safety and efficacy of administering lipid emulsion with ProcalAmine, a glycerol-based parenteral nutrition solution, for peripheral nutrition has not been previously studied. Thirty-four patients recovering from major trauma or surgery were studied while receiving a peripheral parenteral nutrition regimen of either ProcalAmine with 10% lipid emulsion (group 1) or ProcalAmine with 20% lipid emulsion (group 2) for up to 5 days postinjury. Daily dose was 45 mL/kg ProcalAmine, providing 1.35 g of amino acids/kg and 1.35 g of glycero/kg, and 500 mL/day lipid emulsion. The mean daily nitrogen balance was -0.3 g/day in group 1 and -4.1 g/day in group 2. There was no progressive accumulation of circulating glycerol, and urinary glycerol excretion was minimal (less than 0.2 g/day), indicating effective utilization of glycerol as an energy substrate. Our finding that nitrogen balance was better with 10% fat emulsion suggests a limitation in fat utilization in this setting. Both regimens were well tolerated; there were no adverse clinical reactions and no occurrences of phlebitis in either group.
Red-light photosensitized cleavage of DNA by (l-lysine)(phenanthroline base)copper(ii) complexes (2005)

Ternary copper(II) complexes [Cu(l-lys)B(ClO4)](ClO4)(1-4), where B is a heterocyclic base, viz. 2,2'-bipyridine (bpy, 1), 1,10-phenanthroline (phen, 2), dipyrido[3,2-d:2',3'-f]quinoxaline (dpq, 3) and dipyrido[3,2-a:2',3'-c]phenazene (dppz, 4), are prepared and their DNA binding and photo-induced DNA cleavage activity studied (l-lys =l-lysine). Complex 2, structurally characterized by X-ray crystallography, shows a square-pyramidal (4 + 1) coordination geometry in which the N,O-donor l-lysine and N,N-donor heterocyclic base bind at the basal plane and the perchlorate ligand is bonded at the elongated axial site. The crystal structure shows the presence of a pendant cationic amine moiety -(CH2)4NH3+ of l-lysine. The one-electron paramagnetic complexes display a d-d band in the range of 598-762 nm in DMF and exhibit cyclic voltammetric response due to Cu(II)/Cu(I) couple in the range of 0.07 to -0.20 V vs. SCE in DMF-Tris-HCl buffer. The complexes having phenanthroline bases display good binding propensity to the calf thymus DNA giving an order: 4 (dppz) > 3 (dpq) > 2 (phen)>> 1 (bpy). Control cleavage experiments using pUC19 supercoiled DNA and distamycin suggest major groove binding for the dppz and minor groove binding for the other complexes. Complexes 2-4 show efficient DNA cleavage activity on UV (365 nm) or visible light (694 nm ruby laser) irradiation via a mechanistic pathway involving formation of singlet oxygen as the reactive species. The amino acid l-lysine bound to the metal shows photosensitizing effect at red light, while the heterocyclic bases are primarily DNA groove binders. The dpq and dppz ligands display red light-induced photosensitizing effects in copper-bound form.
