Tentative Phase Relationships in the System CaHfTi 2 O 7 ‐Gd 2 Ti 2 O 7 with up to 15 mol% Additions of Al 2 TiO 5 and MgTi 2 O 5 (2002)

The phase relationships in the CaHfTi 2 O 7 ‐Gd 2 Ti 2 O 7 (zirconolite‐pyrochlore) pseudobinary system were investigated, after heating at 1500°C, because of their importance in the design of pyrochlore‐rich titanate ceramics for immobilization of impure surplus plutonium. Up to 15 mol% of MgTi 2 O 5 and Al 2 TiO 5 were added to CaHfTi 2 O 7 ‐Gd 2 Ti 2 O 7 compositions to elucidate the effects of divalent and trivalent impurities on the phase stability within these systems. From X‐ray diffractometry analysis, scanning electron microscopy, and energy dispersive X‐ray spectrometry, phase formation and compositional stability limits were evaluated. The main phases observed in these systems were pyrochlore, perovskite, and polytypes of zirconolite. The formation of the 2 M ‐, 4 M ‐, and 3 O ‐zirconolite polytypes was dependent on the amount of aluminum or magnesium present. In the magnesium system, a large area of pyrochlore‐only was observed, which indicated that divalent impurities of appropriate ionic size could be readily incorporated in the eightfold site of the pyrochlore. The locations of the tentative phase boundaries are discussed with respect to the chemical composition.

Optical Receiver With Widely Tunable Sensitivity in BiCMOS Technology (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> A monolithically integrated optical receiver with voltage-controlled sensitivity in 0.6-<formula formulatype="inline"><tex>$\mu$</tex></formula>m BiCMOS technology is presented. The transimpedance variations are achieved by varying the control voltage of the voltage-controlled resistor changing its equivalent resistance. The optical receiver design is based on a P-intrinsic-N photodiode and on a mixed current-mode and voltage-mode approach, by using a current conveyor and a voltage amplifier. Thanks to the current-mode signal processing, the bandwidth of the optical receiver is independent of the photodiode capacitance. A linearity error smaller than 2.92%, a sensitivity dynamic range of 83.2 (38.4 dB), an offset voltage smaller than 0.56 mV, a power consumption less than 4.7 mW, and a bandwidth up to 205.5 MHz are achieved. </para>
Deamination of bicyclo[2.2.2]octan-2-yl- and bicyclo[3.2.1]octan-2-yl-amines. Evidence for classical precursors of non-classical carbonium ions (1984)

Bicyclo[2.2.2]octan-2-yl- and exo-bicyclo[3.2.1]octan-2-yl-amines have been deaminated in acetic acid by nitrous acid and via their N-phenyltriazenes; their ethyl N-nitrosocarbamates have also been solvolysed in ethanol. Product distributions by a given method from the structurally Isomeric starting materials are similar to each other and to the common product distribution obtained from bicyclo[2.2.2]-octane-2-yl and exo-bicyclo[3.2.1]octan-2-yl toluene-p-sulphonates. Each amine gives, however, a small but unmistakable excess of the structurally unrearranged product compared (in the case substitution) with the distribution obtained from the solvolysis of the corresponding bicyclo-octyl toluene-p-sulphonates. Each amine gives, however, a small but unmistakable excess of the structurally unrearranged product compared (in the case of substitution)with the distribution obtained from the solovolysis of the corresponding bicyclo-octyl toluene -p-sulphonates. endo-Bicyclo[3.2.1]octan-2-ylamine has also been deaminated in acetic acid by nitrous acid and via its ethyl N-nitrosocarbamate in ethanol. The product ratios of these reactions are characteristically different from those of the isomeric amines but, as far as substitution is concerned, are similar to what is obtained from endo-bicyclo[3.2.1]octan-2-yl toluene-p-sulphonate. A common mechanism describe all the deaminative reactions. We propose that classicalcarbonium ions are the initial products of fragmentation of diazo-intermediates. These are intercepted to only a small extent to give products structurally and sterochemically characteristic of the original amines; to an even smaller extent they rearrange to isomeric classical carbonium ions is rearrangement to non-classical isomers. From both classic carbonium ion is produced as has been implicated in the solvolysis of the corresponding toluene-p-sulphonates. endo-Bicyclo[3.2.1]octan-2-ylamine deamination gives rise to an isomeric symmetrical non-classical carbonium ion, the same one that intervenes in the solvolysis of endo-bicyclo[3.2.1]octan-2-yl toluene-p-sulphonate. Symmetrical and unsymmetrical non-classical carbonium ions once formed give product ratio largely independent of their origins or modes of formation although the symmetrical one appears to undergo a small extent of isomerization to the (more stable) unsymmetrical species. These result are contrasted with those obtained from simple carbocyclic system (without branching at the β-carbon)in which deamination and toluene-p-sulphonate solovolysis give characteristically different and unrelated product distributions.
TOTUM-854 PREVENTS L-NAME-INDUCED ARTERIAL HYPERTENSION IN MICE (2021)

Objective: Arterial Hypertension (HTA) is a major cause of premature death worldwide, with an estimated global prevalence of 1.13 billion people. Polyphenolic compounds have been shown promising effects in the context of HTA management. We have developed Totum-854 (T-854), a polyphenol-rich botanical composition to reduce the risk of developing AHT. We assessed the chronic effect of T-854 on preventing the development of N(G)-Nitro-L-arginine-methyl ester (L-NAME)-induced AHT in mice. Design and method: Twelve-week-old C57Bl6/J mice were divided into 3 groups: Control (n = 11), L-NAME (n = 11), and L-NAME + T-854 (n = 11). L-NAME (100 mg/kg/day) was dissolved in drinking water. Mice were gavaged once a day for three weeks with either T-854 (450 mg/kg) or vehicle. The arterial pressure was assessed using the CODA® Tail-Cuff System every week for three weeks. Effects of T-854 on in vitro angiotensin-converting enzyme (ACE) activity was also assessed by a HPLC-UV method. Results: Body weight evolution was not significantly different between the 3 groups over the study period. As expected, L-NAME increased systolic (SBP; from 105 ± 3 to 130 ± 1 mmHg, p &lt; 0.0001), diastolic (DBP; from 77 ± 3 to 97 ± 2 mmHg, p &lt; 0.0001) and mean (MBP; from 86 ± 3 to 108 ± 2 mmHg, p &lt; 0.0001) blood pressure along the 3 weeks of treatment. Interestingly, in T-854-supplemented mice, SBP was significantly reduced from the first week of supplementation and DBP and MDP from the second week of supplementation. After three weeks of supplementation, T-854 lowered the SBP by 16% (p &lt; 0.0001), the DBP by 20% (p &lt; 0.05) and the MBP by 18 % (p &lt; 0.01), in comparison to L-NAME mice. Moreover, in vitro experiments showed an inhibitory effect of T-854 on ACE activity. Conclusions: In conclusion, this study showed that T-854 prevents L-NAME-induced HTA in mice. ACE inhibition may partly explain the preventive effects of T-854 on HTA development in this model. T-854 is a promising new approach for the prevention of HTA.
Rule-based NOTAM &amp; Weather notification (2011)

Today, commercial airline pilots need to consider various sources of information during flight operation. The documentation is both available on paper or within a digital medium. The extensive amount of information is neither prioritized nor filtered, and therefore lead to information overflow. The consideration of all relevant information from the various sources is performed without electronic support and may potentially lead to misinterpretation of the context. It is also challenging to merge and evaluate all delivered information regarding specific phases of flight as well as unforeseen adversarial scenarios. Jeppesen, integrator for world wide aeronautical information and provider for airborne and ground systems such as Electronic Flight Bags (EFB) and dispatch systems, and Technische Universität Braunschweig, with its Institute for Flight Guidance, have jointly developed a rule-based weather and NOTAM notification system. In order to develop a cockpit notification system, a generic data format has been established that copes with all necessary message types used in commercial and general aviation. The paper discusses the rules and definitions required for the implementation of the concepts described above. It presents possible solutions for the integration into the airline cockpit workflow with the following key objectives: · Development of a concept of business rules for the Rule Based NOTAM and Weather Notification System · Connection of real-time NOTAM and weather source data to a data-driven EFB charting application to apply the business rules · Depiction of relevant NOTAM and weather information as notification to the pilots.
Estimation of Absolute Scale in Monocular SLAM Using Synthetic Data (2020)

This paper addresses the problem of scale estimation in monocular SLAM by estimating absolute distances between camera centers of consecutive image frames.These estimates would improve the overall performance of classical (not deep) SLAM systems and allow metric feature locations to be recovered from a single monocular camera.We propose several network architectures that lead to an improvement of scale estimation accuracy over the state of the art.In addition, we exploit a possibility to train the neural network only with synthetic data derived from a computer graphics simulator.Our key insight is that, using only synthetic training inputs, we can achieve similar scale estimation accuracy as that obtained from real data.This fact indicates that fully annotated simulated data is a viable alternative to existing deep-learning-based SLAM systems trained on real (unlabeled) data.Our experiments with unsupervised domain adaptation also show that the difference in visual appearance between simulated and real data does not affect scale estimation results.Our method operates with low-resolution images (0.03 MP), which makes it practical for real-time SLAM applications with a monocular camera.

Predictive Control Method With Future Zero-Sequence Voltage to Reduce Switching Losses in Three-Phase Voltage Source Inverters (2014)

This paper proposes a predictive control method with zero-sequence voltage injection to efficiently reduce the switching losses of three-phase voltage source inverters (VSIs). In the proposed predictive control method, three-phase future voltage references modified by a zero-sequence voltage injection are generated to clamp one of the three legs with the largest load current. Furthermore, the future zero-sequence voltage, which is produced online with the future voltage and current references in every sampling period, optimally adjusts the clamping duration on each leg, depending on the load angle. In addition, the proposed method selects the zero vector on the basis of the polarity of the future zero-sequence voltage to reduce the switching losses. Using a predefined cost function, the proposed predictive control scheme chooses one optimal voltage state closest to the future voltage references modified by the zero-sequence voltage injection. Therefore, the proposed predictive control method can perform load current control and minimize the switching losses of the VSI under any load condition regardless of the load angle.
MICROAEROSOL ADMINISTRATION OF SYNTHETIC BETA-GAMMA-DIPALMITOYL-L-ALPHA-LECITHIN IN THE RESPIRATORY DISTRESS SYNDOME: A PRELIMINARY REPORT. (1964)

Synthetic L-alpha-lecithin was administered by inhalation to 11 infants suffering from respiratory distress. The L-alpha-lecithin was delivered by microaerosolization, at a concentration of 0.25% in a mixture of equal volumes of propylene glycol and water. This was done with the aim of decreasing the alveolar surface tension. In eight of the treated infants who survived, the respiratory distress was alleviated. The results are inconclusive but they justify further investigation.
A Simple, Cleated DNA Walker That Hangs on to Surfaces (2017)

We designed and demonstrated a single-legged or unipedal walker that has a "cleat" that allows it to persistently associate with a track and make autonomous decisions about movement. The walker is highly processive over long periods of time, as shown by its movement over a microparticle surface suffused with substrate. The simple design can be readily optimized on the basis of simple energetic considerations. The walker can be used for signal amplification and should prove especially valuable for programming amorphous computations within chemical reaction networks.
Concomitant Rib Fractures and Minor Liver or Spleen Injuries in Blunt Trauma: What is the Potential for Missed Diaphragmatic Injuries? (2010)

Nonoperative management (NOM) of blunt liver or spleen injuries (LSI) is widely accepted, but diaphragmatic injuries (DI) can be elusive. We hypothesize that rib fractures and minor LSI (RF+ minor LSI) are associated with DI. Patients with blunt injury undergoing exploratory laparotomy between January 1, 2000, and December 31, 2007, were identified from our registry. The association between injury variables and DI was examined with logistic regression. Organ Injury Scores of the liver and spleen of Grade I/II were defined as "minor." A potentially nonoperative (PNO) patient had a rib fracture and minor LSI but no bowel injury or hypotension (systolic blood pressure less than 90 mmHg). The incidence of DI was 7.5 per cent (53 of 705) overall but 20 per cent (seven of 35) in patients with RF + minor LSI. Nineteen PNO patients had four (21.1%) DIs. RF + LSI (3.26 [1.74-6.12], P < 0.001) and motor vehicle collisions (4.93 [2.36-10.32], P < 0.001) were independently associated with DI. The incidence of laparotomy in all critically ill blunt injury patients (n = 2177) decreased significantly (P = 0.003). RF + minor LSI are associated with DI even when there are no other operative injuries. Because NOM is increasingly accepted, the potential for missed DI exists. When high-quality imaging is not available or is equivocal, further studies should be considered.
High phase-transition temperature for β-AgI to α-AgI and an explanation of the memory effect (1991)

The AgI thermal transition of the \ensuremath{\beta} phase (wurtzite structure) to the \ensuremath{\alpha} phase (body-centered-cubic structure) occurred at a higher temperature (162 \ifmmode^\circ\else\textdegree\fi{}C) than that previously reported (\ensuremath{\sim}147 \ifmmode^\circ\else\textdegree\fi{}C). It is believed that this higher temperature is the result of these gelatin-grown \ensuremath{\beta}-phase microcrystals being unusually free of included \ensuremath{\gamma} phase and other crystal defects that would serve as \ensuremath{\alpha}-phase nucleation sites. Introducing defects into these grains catalyzed this transition at the lower temperature. Having two distinct phase-transition temperatures explains the memory effect that has been reported in some AgI microcrystalline samples.
Dehydrogenative Synthesis of Imines from Alcohols and Amines Catalyzed by a Ruthenium N-Heterocyclic Carbene Complex (2011)

A new method for the direct synthesis of imines from alcohols and amines is described where hydrogen gas is liberated. The reaction is catalyzed by the ruthenium N-heterocyclic carbene complex [RuCl2(IiPr)(p-cymene)] in the presence of the ligand DABCO and molecular sieves. The imination can be applied to a variety of primary alcohols and amines and can be combined with a subsequent addition reaction. A deuterium labeling experiment indicates that the catalytically active species is a ruthenium dihydride. The reaction is believed to proceed by initial dehydrogenation of the alcohol to the aldehyde, which stays coordinated to ruthenium. Nucleophilic attack of the amine affords the hemiaminal, which is released from ruthenium and converted into the imine.
Multipath packet switch using packet bundling (2003)

The basic concept of packet bundling is to group smaller packets into larger packets based on, e.g., quality of service or destination within the packet switch.This paper presents novel applications of bundling in packet switching.The larger packets created by bundling are utilized to extend switching capacity by use of parallel switch planes.During the bundling operation, packets will experience a delay that depends on the actual implementation of the bundling and scheduling scheme.Analytical results for delay bounds and buffer size requirements are presented for a specific scheduling algorithm, and compared to simulation results.
The issues of transport multiplicity and energetics pertaining to methotrexate efflux in L1210 cells addressed by an analysis of cis and trans effects of inhibitors. (1991)

Studies are described addressing the controversial issue of the multiplicity of efflux routes for [3H]MTX in L1210 cells. We examined efflux multiplicity under conditions that do and do not maintain cellular ATP at the physiological level. In ATP-replete cells, the results delineate a probenecid-, bromosulfophthalein-, and verapamil-inhibitable route that accounts for nearly 90% of [3H]MTX efflux. Efflux of [3H]MTX by this route is inhibited by bromosulfophthalein in the trans orientation only, inhibited by probenecid only when present simultaneously in the cis and trans orientation and inhibited by verapamil only in the cis orientation. The remaining efflux of this folate analogue in ATP-replete cells appears to be mediated by the one-carbon, reduced folate system (MTX influx route), in that it is not inhibited by bromosulfophthalein or verapamil but is inhibited by the N-hydroxysuccinimide ester of MTX, a specific inhibitor of MTX influx, and a 10-fold higher concentration of probenecid than that required to inhibit ATP-dependent efflux. Under these conditions, MTX did not trans-stimulate [3H]MTX efflux. Also, no evidence was obtained for a putative bromosulfophthalein-insensitive, probenecid-inhibitable route for [3H]MTX efflux. In cells depleted to the extent of 90-95% of their ATP by 60-min incubation in medium in the absence of D-glucose and with 10 mM sodium azide, overall efflux of [3H]MTX was markedly reduced and appears to be mediated solely by the MTX influx route. Influx of [3H]MTX was both cis and trans inhibited by probenecid, and efflux under these conditions was markedly inhibited by the N-hydroxysuccinimide ester of MTX and trans-stimulated by MTX. Overall, the results of these studies are consistent with a model for methotrexate transport in L1210 cells derived [Dembo et al., J. Membrane Biol., 78: 9-17, 1984] in the authors' laboratory based solely upon a kinetic analysis of [3H]MTX influx and efflux in ATP-replete and depleted L1210 cells. As such, these new results identify a single ATP-dependent efflux route as the bromosulfophthalein-, probenecid-, and verapamil-inhibitable route in L1210 cells under conditions that maintain ATP levels at maximum.
Agency and Motivation in Adulthood and Old Age (2018)

This review addresses conceptual and empirical research about how individual agency and motivation influences development during adulthood and old age. The major life-span approaches to individual agency and developmental regulation are discussed, with a focus on the motivational theory of life-span development. Developmental agency unfolds through action cycles of pursuing long-term goals for optimal development. Individuals differ in their capacity to regulate their goal engagements effectively within the age-graded structure of opportunities and constraints in their life courses. We discuss a set of research examples about specific developmental challenges, such as transition to adulthood, biological aging, illness, and societal transformation, and show how individuals, as agents in their own development, navigate change for better or worse. We conclude with suggestions for future research.

Accuracy Assessment of Steady and Unsteady Multistage High Pressure Compressor Simulations (2019)

Abstract In this paper a comparison of the performance parameters and flow characteristics of a mature commercial high bypass engine’s 9-stages high pressure compressor (HPC) with steady-state mixing-plane (RANS) and unsteady RANS (URANS) CFD is carried out. The investigation is based on a numerical model of the CFM56-5C engine’s HPC which is installed on the Airbus A340-300 aircraft. The compressor under investigation features the so called 3D blading which is the first of two performance improvement packages available. An experimental engine of this type equipped with extensive additional instrumentation is in use by Lufthansa Technik to deliver detailed experimental data of the gas path. Experimental results have been discussed in previous works of the authors. In order to provide long-term forecasts of an engine’s state the aforementioned CFD model has been included into a multilevel engine model. To be able to evaluate the significance and applicability of the CFD results into such model, it is of great interest to which extent and level of detail it can deliver accurate performance predictions. From the comparison of both steady-state and unsteady simulation results it is found that overall compressor performance only differs negligibly while stage performance can differ significantly. It is depicted that among the stator vanes of the front stages local supersonic flow and flow separation can occur. These are not captured by the steady-state simulation to the same degree a time resolved simulation does. In rear stages differences fade and unsteady methods tend to predict better stage performance which may be due to favourable effects of rotor-stator interaction.
On Quantum Integers and Rationals (2015)

We introduce the notions of quantum characteristic and quantum flatness for arbitrary rings. More generally, we develop the theory of quantum integers in a ring and show that the hypothesis of quantum flatness together with positive quantum characteristic generalizes the usual notion of prime positive characteristic. We also explain how one can define quantum rational numbers in a ring and introduce the notion of twisted powers.
Optimizing the aqueous phase synthesis of CdTe quantum dots using mixed-ligands system and their applications for imaging of live cancer cells and tumors in vivo (2013)

Quantum dots (QDs) exhibit unique optical properties including size-tunable fluorescence, superior brightness, broad absorption and tiny emission bandwidth. These properties have made QDs promising candidates for bioimaging and biosensing applications. In this work, CdTe QDs were synthesized in aqueous phase using both mercaptopropionic acid (MPA) and Cysteine (Cys) as capping agents. Growth kinetics and optical properties of the resulted QDs were found to be dependent on both species and concentration of surfactant molecules. Considering the distinct nature and advantages of MPA and Cys, a mixed-ligands system was proposed as a potential approach to fabricate QDs with specific optical property and functions for in vitro and in vivo bioimaging applications.
