Ein Beitrag zur Beurteilung verschleißfester Nickel‐Bor‐Silicium‐Hartlegierungen (1977)

Abstract Nickel‐Bor‐Silizium‐Legierungspulver werden als Oberflächenbeschichtungsmaterialien zum Verschleiß‐ und Korrosionsschutz verarbeitet. Sie sollen nach dem Aufbringen auf Eisenbasiswerkstoffe bereits ihre Gebrauchseigenschaften besitzen, die jedoch stark vom thermodynamischen Gleichgewichtszustand und damit von dem volumenmäßigen Verhältnis der Nickelmatrix zu den eingelagerten Hart‐phasen bestimmt werden. Zur Abschätzung der Gebrauchseigenschaften ist es deshalb nötig, die Phasenverhältnisse in Abhängigkeit der Gleichgewichtstemperatur und der Aufmischung mit dem jeweiligen Grundwerkstoff zu kennen.
3D Foveated Visualization on the Web (2007)

Recent developments in Internet technology, combined with the computerisation of hospital radiology departments, allow the remote viewing of medical data images. Generally, however, medical images are data intensive and the transmission of such images over a network can consume large amounts of network resources. Previous work by Liptay et al, 6 presented an interactive, progressive program (implemented in JAVA and requiring a web browser) that allowed the transmission of multi-resolution JPEG image data using various ROI (Region of Interest) strategies in order to minimise Internet bandwidth requirements. This work handled both 2D and 3D image data, but 3D data was treated as a sequence of 2D images, where each 2D image had to be individually requested by the system. The work described in this paper replaces the representation of 3D data as a 2D JPEG image sequence with a single block of lossy 3D image data compressed using wavelets. In a similar fashion, 2D image data is wavelet co...
Intelligent Hydrogels Via Gamma‐Ray Induced Polymerization of Micellar Monomer Solutions and Microemulsions (2010)

Abstract Summary: Intelligent hydrogels were prepared upon polymerization of micellar aqueous comonomer solutions and microemulsions containing the cationic surfactant monomer 11‐acryloyloxyundecyltrimethylammonium bromide (AUTMAB) and N‐isopropylacrylamide (NIPAM). A chemically and physically cross‐linked network structure is formed consisting of blocks of P‐NIPAM and P‐AUTMAB. The P‐AUTMAB blocks act as physical cross‐linking units improving the mechanical stability of the gel. While pure P‐NIPAM hydrogels are disrupted under low compression, gels polymerized from micellar solution or microemulsion can be reversibly compressed. The presence of AUTMAB in the gel increases the swelling up to a factor of 30 compared with the pure P‐NIPAM gel. Rapid and reversible swelling is observed for hydrogels with an AUTMAB content up to 2.5 wt.‐%.
Talking with an APL via DDE (1993)

Shared variables and auxiliary processors are well-known techniques for connecting alien applications to APL. The use of APL in the PC windowing multitasking environment of MS Windows, which incorporates a messaging model for interprocess communications, requires some new approaches to the implementation of shared variable and auxiliary processor support. This paper presents a shared variable interface to MS Windows graphics written in Microsoft C and a simple charting package called TinyPlot written in Dyalog APL for Windows (Dyalog APL/W). The purpose of this paper is to demonstrate and investigate the Dyalog APL/W shared variable and auxiliary processor facilities, and to offer observations and conclusions about the benefits, limitations, and potential of the Dynamic Data Exchange interface generally.
Efficient Photometric Alignment for Around View Monitor System (2019)

Around view monitor system has become a typical advanced driver-assistance system. Nevertheless, due to the differences between the lenses and sensors, the output image of around view monitor system inevitably has the visible brightness difference at the overlapping area of the images, and there are still obvious seams in the image mosaic. Photometric alignment aims to match the brightness of images under different illumination conditions and can be used to eliminate seams in the stitching image. The existing photometric alignment methods are mainly based on the gain compensation of three RGB channels, which not only increase the computational complexity but also affect the quality of output image. This paper proposes a new photometric alignment algorithm based on brightness channel and image fusion technology. Experimental results demonstrate that the seams in the final bird's-eye view are smoothly compensated.
Circulating sphingolipid biomarkers in models of type 1 diabetes (2010)

Alterations in lipid metabolism may contribute to diabetic complications. Sphingolipids are essential components of cell membranes and have essential roles in homeostasis and in the initiation and progression of disease. However, the role of sphingolipids in type 1 diabetes remains largely unexplored. Therefore, we sought to quantify sphingolipid metabolites by LC-MS/MS from two animal models of type 1 diabetes (streptozotocin-induced diabetic rats and Ins2(Akita) diabetic mice) to identify putative therapeutic targets and biomarkers. The results reveal that sphingosine-1-phosphate (So1P) is elevated in both diabetic models in comparison to respective control animals. In addition, diabetic animals demonstrated reductions in plasma levels of omega-9 24:1 (nervonic acid)-containing ceramide, sphingomyelin, and cerebrosides. Reduction of 24:1-esterfied sphingolipids was also observed in liver and heart. Nutritional stress via a high-fat diet also reduced 24:1 content in the plasma and liver of mice, exacerbating the decrease in some cases where diabetes was also present. Subcutaneous insulin corrected both circulating So1P and 24:1 levels in the murine diabetic model. Thus, changes in circulating sphingolipids, as evidenced by an increase in bioactive So1P and a reduction in cardio- and neuro-protective omega-9 esterified sphingolipids, may serve as biomarkers for type 1 diabetes and represent novel therapeutic targets.
Disseminated infection due to<i>Mycobacterium bovis</i>after intravesical BCG instillation (2014)

Intravesical bacillus Calmette-Guerin (BCG) instillation has been adopted for the treatment of patients with superficial bladder cancer. Severe adverse events due to local instillation of BCG are uncommon, with an overall rate of serious complications of less than 5%. We report the case of an immunocompetent adult patient with multi-system effects, namely pneumonitis, granulomatous hepatitis and meningitis, who responded well to standard treatment for Mycobacterium bovis. This case highlights the importance of a thorough assessment of this type of patient.
"How I do it: utilization of high-pressure sealants in aortic reconstruction" (2009)

In major aortic reconstructive procedures the need for anastomotic sealing performance, reinforcement of friable tissues, and adhesion prevention should not be underrated. High-pressure surgical sealants represent an important surgical adjunct, and the author has found the use of both PEG sealant and BSAG glue advantageous in aortic reconstruction and repair.
NMR Detection with an Atomic Magnetometer (2005)

We demonstrate detection of NMR signals using a noncryogenic atomic magnetometer and describe several novel applications of this technique. A nuclear spin-precession signal from water is detected using a spin-exchange-relaxation-free potassium magnetometer. We also demonstrate detection of less than 10(13) 129Xe atoms whose NMR signal is enhanced by a factor of 540 due to Fermi-contact interaction with K atoms. The possibility of using a multichannel atomic magnetometer for fast 3D magnetic resonance imaging is also discussed.
Energy Efficient Hydraulic Hybrid Drives (2009)

Energy efficiency of propulsion systems for cars, trucks and construction machineries has become one of the most important topics in today’s mobile system design, mainly because of increased fuel costs and new regulations about engine emissions, which is needed to save the environment. To meet the increased requirements on higher efficiency and better functionality, components and systems have been developed over the years. For the last ten years the development of hybrid systems can be divided into two major technologies, electric hybrids and hydraulic hybrids. Today, there is a hard competition between these two branches. Therefore, it is interesting to compare these two technologies to figure out their individual capabilities. This paper will discover the advantages of hydraulic hybrid systems over electric hybrids and how to succeed with the hybrid system design. One obvious advantage with hydraulic hybrid systems is that they create a unique opportunity to optimize the engine loading at all speeds. About the power density, hydraulic machines have around 5 times higher density than electric machines. This gives the opportunity to use direct hydraulic drive and remove mechanical gearings needed in an electric hybrid system. This fact has a large impact on the system overall efficiency. By using hydraulic accumulators, a part of the potential load energy can be reused, which make it possible to design a system with improved endurance compared with a similar one without such devices. This kind of regenerative capabilities increase the power supply capability. The additional power can be used to improve the performance of the system, without increasing the primary engine power. Another advantage of using a hydraulic accumulator is that its round-trip efficiency is higher than for an electric battery, especially at frequent acceleration and braking.
A Model of Exchange Rate Pass-Through (1987)

Exchange rate pass-through is the phenomenon whereby changes in the value of foreign exchange are reflected in changes in import prices. This paper presents a model in which firms are price setters who anticipate exchange rate changes. In equilibrium, firms' strategies incorporate expectations about the exchange rate consistently and are best responses to the strategies of all others in the world market. It is shown that exchange rate changes give rise to import price changes, but the degree of exchange rate pass-through depends upon domestic and foreign market structures and the exchange rate regime. In general, exchange rate pass-through is higher if the home market is monopolistic or if the foreign market is competitive. The paper concludes with an examination of disaggregated Japanese manufacturing price indices, and it shows that the degree of exchange rate pass-through was indeed correlated with industry concentration during the most recent period of the yen's depreciation against the dollar.
Remembering Sugihara, Re-framing Japan in Europe: Holocaust Era Altruism and the Politics of Cultural Memory (2006)

Cornell University This paper is a comparison of two museums dedicated to the Japanese diplomat to Lithuania during World War II, Sugihara Chiune. Credited with having written over 6,000 visas to save the lives of Jews fleeing German occupied Poland into Lithuania, Sugihara is regarded in Europe, in Japan, and within the Jewish community as a whole as an altruistic person. This study is not an inquiry into the merits of Sugihara’s action, but rather a study of how the process of memorializing, narrativizing and celebrating the life of Sugihara in two vastly different museums is part of a larger project of selective cultural memory on the part of various Japanese organizations and institutions. This paper situates the themes of altruism and heroism in the larger process of cultural memory, to see how such themes operate to advance other projects of collective memory. The case of Sugihara is fascinating precisely because the vastly differing processes of cultural memory of the Holocaust―in Lithuania, in Japan, and in a wider post-World War II, post Holocaust Jewish Diaspora each have different ways of constructing, disseminating and consuming narratives of altruism. This paper is based on fieldwork in Kaunas and Vilnius, Lithuania, in 2003, 2004 and again in 2005 and in Japan in 2005.
Obstacle Recognition Based on Machine Learning for On-Chip LiDAR Sensors in a Cyber-Physical System (2017)

Collision avoidance is an important feature in advanced driver-assistance systems, aimed at providing correct, timely and reliable warnings before an imminent collision (with objects, vehicles, pedestrians, etc.). The obstacle recognition library is designed and implemented to address the design and evaluation of obstacle detection in a transportation cyber-physical system. The library is integrated into a co-simulation framework that is supported on the interaction between SCANeR software and Matlab/Simulink. From the best of the authors' knowledge, two main contributions are reported in this paper. Firstly, the modelling and simulation of virtual on-chip light detection and ranging sensors in a cyber-physical system, for traffic scenarios, is presented. The cyber-physical system is designed and implemented in SCANeR. Secondly, three specific artificial intelligence-based methods for obstacle recognition libraries are also designed and applied using a sensory information database provided by SCANeR. The computational library has three methods for obstacle detection: a multi-layer perceptron neural network, a self-organization map and a support vector machine. Finally, a comparison among these methods under different weather conditions is presented, with very promising results in terms of accuracy. The best results are achieved using the multi-layer perceptron in sunny and foggy conditions, the support vector machine in rainy conditions and the self-organized map in snowy conditions.
Highly coherent thermal emission obtained by plasmonic bandgap structures (2008)

We demonstrate an extraordinary quasimonochromatic thermal emission with high spatial coherence length (lc&gt;2400λ) and a quality factor Q=2320 at radiation frequencies that are much smaller than the plasma frequency of metal (ω≪ωp). This emission is achieved by forming a plasmonic bandgap, which is obtained by a periodic structure on a metallic surface. Such a structure modifies the dynamics of the surface wave and results in a van Hove singularity [Van Hove, Phys. Rev. 89, 1189 (1953)] in the spectral density of states while maintaining a large coherence length.
Mitochondrial Fusion in Human Cells Is Efficient, Requires the Inner Membrane Potential, and Is Mediated by Mitofusins (2002)

Mitochondrial fusion remains a largely unknown process despite its observation by live microscopy and the identification of few implicated proteins. Using green and red fluorescent proteins targeted to the mitochondrial matrix, we show that mitochondrial fusion in human cells is efficient and achieves complete mixing of matrix contents within 12 h. This process is maintained in the absence of a functional respiratory chain, despite disruption of microtubules or after significant reduction of cellular ATP levels. In contrast, mitochondrial fusion is completely inhibited by protonophores that dissipate the inner membrane potential. This inhibition, which results in rapid fragmentation of mitochondrial filaments, is reversible: small and punctate mitochondria fuse to reform elongated and interconnected ones upon withdrawal of protonophores. Expression of wild-type or dominant-negative dynamin-related protein 1 showed that fragmentation is due to dynamin-related protein 1-mediated mitochondrial division. On the other hand, expression of mitofusin 1 (Mfn1), one of the human Fzo homologues, increased mitochondrial length and interconnectivity. This process, but not Mfn1 targeting, was dependent on the inner membrane potential, indicating that overexpressed Mfn1 stimulates fusion. These results show that human mitochondria represent a single cellular compartment whose exchanges and interconnectivity are dynamically regulated by the balance between continuous fusion and fission reactions.
Towards incremental learning of task-dependent action sequences using probabilistic parsing (2011)

We study an incremental process of learning where a set of generic basic actions are used to learn higher-level task-dependent action sequences. A task-dependent action sequence is learned by associating the goal given by a human demonstrator with the task-independent, general-purpose actions in the action repertoire. This process of contextualization is done using probabilistic parsing. We propose stochastic context-free grammars as the representational framework due to its robustness to noise, structural flexibility, and easiness on defining task-independent actions. We demonstrate our implementation on a real-world scenario using a humanoid robot and report implementation issues we had.
Enhancing Phosphorescence and Electrophosphorescence Efficiency of Cyclometalated Pt(II) Compounds with Triarylboron (2010)

Abstract A synthetic strategy for the preparation of cyclometalated platinum(II) acetylacetonate (acac) complexes functionalized with triarylboron is achieved. This method is used to synthesize a series of triarylboron‐functionalized phosphorescent Pt(acac) compounds, which are characterized by NMR spectroscopy, X‐ray crystallography, and theoretical calculations. These complexes exhibit a range of bright phosphorescent colors spanning the green to red region of the visible spectrum ( λ max = ∼520–650 nm) in solution and the solid state. Functionalization with a triarylboron group leads to significant enhancement in quantum yield for several of these complexes relative to the non‐borylated Pt(II) parent chromophores, which may be attributed to the increased mixing of 1 MLCT and 3 LC states. The phosphorescent enhancement, electron transport capabilities, and steric bulkiness offered by the triarylboron group can be used to significantly enhance the performance of electrophosphorescent devices based on Pt(II) emitters. A high efficiency green electrophosphorescent device is fabricated with a maximum external quantum efficiency of 8.9%, luminance efficiency of 34.5 cd A −1 , and power efficiency of 29.8 lm W −1 , giving significantly improved performance over control devices in which the Pt(II) emitter lacks the boron functionality.

A comparison of Taiwanese sign language and manually coded Chinese: word length and short-term memory capacity (2019)

Taiwanese Sign Language (TSL) is the natural language among deaf communities in Taiwan. Manually Coded Chinese (MCC) is the official instructional language. Previous studies have shown that the deaf students have great difficulty in comprehending stories in MCC, plausibly due to greater word length in MCC, which in turn may impair recall of MCC words. In Study I, deaf and hearing signers produced signs for 100 words in both MCC and TSL, and the word length was calculated for each sign pairs. It was found that MCC words were greater in length than the TSL words, whether produced by a hearing or a deaf signer. In Study II, the short-term memory capacity in the deaf signers was compared between word lists in TSL and in MCC. The participants were 44 senior high students in the deaf school and 20 deaf adults. The results showed that for deaf students and adults, the short-term memory capacity was inferior for the MCC list than for the TSL list, confirming our hypothesis.
Comparison of Different Open Addressing Hashing Algorithms. (2003)

Hash functions are among the oldest and most widely used data structures in computer science. Different hash functions exist. So, it is very important to compare their performance. In this paper, we introduced our new hash function which was proposed recently in [1], and compared its performance with two different open addressing hashing algorithms: double hashing and exponential hashing. Double hashing is a widely-used hash function, which offers good performance. Exponential hashing, proposed by Smith et al [2], has been shown through experimental analysis to be superior to double hashing when the data elements are not uniformly distributed. The good performance of exponential hashing is due to its ability of spreading the table elements more randomly than double hashing. While exponential hashing has some desirable characteristics, Smith points out that it produces less than full probe length on 1/2 of the table elements. This is undesirable since it could potentially lead to insertion and search failures. Our new hash function has the ability of spreading the table elements randomly, and produces full probe length on all the table elements at the same time. From this point of view, our new hash function combines the strength of both double hashing and exponential hashing with their weakness eliminated. Experimental results are presented to support our claims, which is followed by some theoretic analysis.
A Microscopic View of Laser Ablation (1998)

Recent applications of the breathing sphere model for molecular dynamics simulations of laser ablation of organic solids have yielded detailed microscopic data of the processes involved. The results to date include a prediction of a fluence threshold for ablation, an explanation for the presence of clusters in the plume and a consistent analytical description of the velocity distribution for both matrix molecules and heavier analyte molecules in matrix-assisted laser desorption. In this paper we review the approach and the basic physical picture that emerges from the simulations, present new results, and discuss future prospects for microscopic simulations of laser ablation.
Cloning of a complementary deoxyribonucleic acid encoding the murine homolog of the very low density lipoprotein/apolipoprotein-E receptor: expression pattern and assignment of the gene to mouse chromosome 19. (1994)

We report the cloning of a complementary DNA for the mouse homolog of the very low density lipoprotein (VLDL)/apolipoprotein-E receptor (VLDLR), the deduced amino acid sequence of the protein, and the mapping of the gene encoding the receptor to mouse chromosome 19. Northern hybridization revealed that the VLDLR messenger RNA (mRNA) is most abundant in skeletal muscle, heart, kidney, and brain. It was also detected in lung and in low levels in liver, but it was not found in spleen or testes. Levels of VLDLR mRNA in mouse placenta increased from days 8-18 of gestation. The VLDLR mRNA was induced in 3T3-L1 cells undergoing differentiation into adipocytes. The increase in VLDLR mRNA paralleled the rise in lipoprotein lipase and hormone-sensitive lipase mRNAs. However, VLDLR and low density lipoprotein receptor-related protein were increased in the presence of retinoic acid, whereas the induction of lipoprotein lipase and hormone-sensitive lipase mRNAs was inhibited. Our observations demonstrate regulated expression of the VLDLR gene in placenta and adipocytes, where the receptor protein may play roles in the uptake of triglyceride-rich particles for storage of lipid (adipocytes) or for lipid transport to the fetus (placenta). The availability of a murine complementary DNA probe and the knowledge of the map position of the VLDLR gene in the mouse genome will facilitate studies on the function and regulation of this protein.
