Improving P2P live-content delivery using SVC (2010)

P2P content delivery techniques for video transmission have become of high interest in the last years. With the involvement of client into the delivery process, P2P approaches can significantly reduce the load and cost on servers, especially for popular services. However, previous studies have already pointed out the unreliability of P2P-based live streaming approaches due to peer churn, where peers may ungracefully leave the P2P infrastructure, typically an overlay networks. Peers ungracefully leaving the system cause connection losses in the overlay, which require repair operations. During such repair operations, which typically take a few roundtrip times, no data is received from the lost connection. While taking low delay for fast-channel tune-in into account as a key feature for broadcast-like streaming applications, the P2P live streaming approach can only rely on a certain media pre-buffer during such repair operations. In this paper, multi-tree based Application Layer Multicast as a P2P overlay technique for live streaming is considered. The use of Flow Forwarding (FF), a.k.a. Retransmission, or Forward Error Correction (FEC) in combination with Scalable video Coding (SVC) for concealment during overlay repair operations is shown. Furthermore the benefits of using SVC over the use of AVC single layer transmission are presented.
Mask blank particle inspection in vacuum environments (2002)

The mask blank surface inspection system for the electron beam mask writing system (EB mask writer) has developed. This system, that has the small vacuum chamber attachable to EB mask writer, inspects a mask blank that is just before EB writing in vacuum environments. It can inspect whole area of the 230mm mask at 0.3micrometer sensitivity. It also can perform fast inspection by applying the original scanning algorithm for the laser beam. It has the wide detective range from 0.3 to 2.0 micrometers of particle size. It can distinguish sizes of particles in that range. The auto focus function is most important factor for maintaining the sensitivity.
Hydrothermische Behandlung von Stärke in Gegenwart von Maltosesirup. Teil 1. Einfluß auf DSC-Parameter und die Konsistenz von Kartoffelstärkegelen (1998)

Eine hydrothermische Modifizierung von Kartoffelstärke bei Wasserüberschuß in Gegenwart von Maltosesirup erlaubt eine gezielte Veränderung von Verkleisterungs- und Geleigenschaften bei weitgehender Erhaltung der granulären Struktur. Die Temperung in Maltosesirup bewirkt einen starken Rückgang der Heißkonsistenz und eine Erhöhung der Brabender-Konsistenz während der Haltephase bei 96°C. 3,3%ige Stärkekleister solcher Proben ergeben bei einer Brabender-Endtemperatur von 50°C Nachdickungswerte von ca. 2300 BE. Die Temperung von Kartoffelstärke in Maltosesirup steigert die Brabender-Endkonsistenz auf etwa das Doppelte bei Ausbeuteverlusten von < 10%. Gelelastizitätsuntersuchungen ergaben sag-Werte von ca. 20%. Gelkegel mit 3,3% Kartoffelstärke, modifiziert in 6%igem Maltosesirup bis zu einer Endtemperatur von 56°C, erreichen sag-Werte von 17%. Die Alkali-Brabender-Zeit steigt in diesen Proben um das 4fache an und die DSC-Quellungstemperatur Tmax erreicht Werte, die um 5,5 bis 8 K erhöht sind. Die Temperung von Kartoffelstärke in Maltosesirup ermöglicht durch kurzzeitige Energie einsparende Temperung Eigenschaftsveränderungen an Kartoffelstärken vorzunehmen, die ein breites industrielles Einsatzspektrum eröffnen. Hydrothermal treatment of starch in presence of maltose syrup. Part 1. Effect on DSC Parameters and consistency of potato starch gels A hydrothermal modification of potato starch at water excess in presence of maltose syrup permits distinct changes of properties as paste consistency, gelatinization and gelation behaviour preserving the granular structure at the same time. Annealing in maltose syrup causes a drastic decrease in hot past consistency and an increase in consistency during the keeping phase at 96°C. 3.3% starch in pastes of such samples produces a set back of about 2300 BU at a Brabender final temperature of 50°C. Annealing of potato starch in maltose syrup doubles Brabender final consistency with minimal loss in yield (< 10%). Modified patterns show a gel elasticity of about 20%-sag measured in ridgelimeter. Gel bevels composed of 3.3% annealed starch modified in 6%ical maltose syrup up to a final temperature of 56°C are characterized by sag values of 17%. The alkaline stability measured in Brabender viscograph rises 4 fold in these samples and show a shift of the DSC swelling temperature Tmax of 5.5 to 8 K. Annealing of potato starch in maltose syrup makes it possible to alter properties within a short time at very low energy consumption offering broad industrial application.

An IoT Based Disaster Response Solution for Ocean Environment (2020)

This paper discusses the importance of an emergency response system for the ocean disasters that affect the life of the fisher community. Ocean emergencies can vary from the extreme climatic conditions, collision between boats and ships as well as other unexpected health emergencies that may be faced by the older fishermen while at the ocean. We discuss the challenges in implementing disaster response activities in ocean scenarios and propose an IoT solution for the fisher community to help them during emergencies as well as to maintain frequent communication with the shore. This paper also presents how this IoT solution can bring a change in the fishermen’s life and how our solution can be used when they are in danger. We also proposed a partial-context aware algorithm that helps to monitor the fishing vessel movements and how this algorithm can help during an emergency.
Distortion Measures in MPEG-Compressed Domain for Multidimensional Transcoding (2005)

In order to find the optimal combination of spatio-SNR-temporal transcoding operations, we need to measure the distortion due to the transcoding operations. In this paper, we develop computational methods to calculate the distortion by using only the information extracted directly from the input bitstream through a minimum decoding process in the DCT domain. The objective of our distortion modeling is to estimate the multidimensional distortion before the entire transcoding process
Theory of the heat of solution of hydrogen in Al and Mg using nonlinear screening (1976)

A theory of the heat of solution of hydrogen in simple metals is developed and results are presented for the cases of aluminum and magnesium. The electronic contribution to the heat of solution is treated within the framework of local pseudopotential theory and is based on linear screening. For the proton contribution it is necessary to use nonlinear theory for the screening of the proton and a convenient framework for this is the density functional formalism with exchange and correlation corrections included approximately. The calculated value of the heat of solution for aluminum is 0.45 eV which compares favorably with the experimental value of 0.66 eV. The result for magnesium, -0.05 eV, is also in reasonable agreement with the experimental value of 0.25 eV bearing in mind that the hydrogen heat of solution is obtained as the difference of two energies of about 15 eV. The energy has also been investigated as a function of the position of the proton in the lattice. Calculated energy barriers are used to estimate proton diffusion parameters.
Glycerol-Ester Hydrolase from Human Small Intestine and Its Possible Role in the Degradation of Neutral Lipids (1977)

A glycerol-ester hydrolase has been characterized and partially purified (23-fold) from human small intestine. A pancreatic origin was excluded through the use of an immunoserum directed against human pancreatic juice, while a pharyngeal (gastric) origin was unlikely owing to the optimum pH range of activity of the gastric enzyme as compared to that of the intestinal enzyme. The glycerol-ester hydrolase is mainly active toward short-and medium-chain di- and triglycerides and toward micellar long-chain monoglycerides. A role in the absorption of neutral lipids, mainly in pathological situations, is postulated.
Robotics Workforce Training, Offshore Energy Transformation (2023)

Abstract There is an increasing demand for robotics systems in production, inspection, and maintenance in the energy industry from offshore to onshore, to reduce operating costs and lower the risk of exposing humans to hazardous environments. However, a gap exists between existing workforce expertise and technologies that are developing rapidly. The deployment of robots requires the engineer to have rich experience in production and sufficient understanding of the robotic multidisciplinary system so they can identify and deploy the robot in the use case that can maximize the robot's efficiency. The nature of robotics and automation presents a challenge to the workforce since the existing workforce's background, in specific engineering disciplines or business, hinders them from adapting and then keeping up with the transition to robotic (not normally manned) operations. Directed by the University of Houston, the Subsea Systems Institute (SSI) is developing, in collaboration with Sprint Robotics, the National Robotarium (UK) and the Society of Underwater Technology (SUT), a robotic training program. The objective is to upskill and reskill the energy industry personnel (offshore and onshore) to meet the emerging industry demand for multidisciplinary robotics expertise. This group is collaborating to fill the gap between required knowledge and application in the energy industry by identifying the necessary knowledge and skillsets, and then developing an adaptable modular program with use cases to train the existing workforce. The SSI led effort will adjust to the differing needs that drive the adoption of this evolving technology, including engineers and scientists and other stakeholders such as managers, influencers, and the public.
Mechanistic studies on the formal aza-Diels–Alder reactions of N-aryl imines: evidence for the non-concertedness under Lewis-acid catalysed conditions (2004)

The reaction of a para-methoxyaniline, ethyl glyoxalate-derived imine with a series of dienes has resulted in products, which initially suggest the operation of different modes of aza-Diels-Alder reaction. However, a more likely explanation is that a common reaction mechanism is operating, involving a step-wise Lewis-acid catalysed process, which only appears to behave similarly to alternative concerted cycloaddition reactions.
Genetic linkage and association between chromosome 1q and working memory function in schizophrenia (2002)

Schizophrenia is substantially heritable, but specific susceptibility genes remain to be identified. Progress in this endeavor has been hindered by non-Mendelian transmission patterns, probable genetic heterogeneity, and an inability to detect premorbid and nonpenetrant carriers of predisposing genes. To circumvent these complexities, this study employed quantitative measures of liability, or "endophenotypes," within a sample of twins discordant for schizophrenia, drawn from the relatively genetically isolated population of Finland. A region on the distal portion of chromosome 1 has shown evidence for linkage to schizophrenia in two prior studies using Finnish patient samples. To elucidate further the nature and location of this potential susceptibility gene, linkage and association analyses were carried out across the chromosome 1 region of interest using quantitative neuropsychological measures of liability. Analyses with a composite measure of liability yielded suggestive evidence for linkage at marker D1S2833 (P = 0.04). Follow-up analyses of the individual trait measures showed that the Visual Span subtest of the Wechsler Memory Scale (WMS), an indicator of spatial working memory function, was uniquely sensitive to marker D1S2833 (P = 0.007). Association analysis confirmed that allelic variation in D1S2833 is associated with variation in spatial working memory performance as measured by the Visual Span subtest (P = 0.003), the significance of which was confirmed in an analysis of 10,000 Monte Carlo permutations. These data support the utility of this approach and provide evidence for a gene affecting spatial working memory function in schizophrenia patients and their unaffected co-twins.
Tivantinib (ARQ 197) efficacy is independent of MET inhibition in non‐small‐cell lung cancer cell lines (2014)

MET targeted therapies are under clinical evaluation for non-small-cell lung cancer (NSCLC) patients. Tyrosine kinase inhibitors (TKI) against MET have varying degrees of specificity. Tivantinib (ARQ 197) is reported to be a non-ATP competitive selective MET inhibitor. We aimed to compare the activity of tivantinib to established MET TKIs in a panel of NSCLC cell lines characterized by their MET dependency and by different relevant genotypes. A549, H3122, PC9 and HCC827, their respective resistant clones PC9 GR4 and HCC827 GR6 and the MET amplified cell lines H1993 and EBC-1 were treated in vitro with tivantinib, crizotinib or PHA-665752. Crizotinib and PHA-665752 showed growth inhibition restricted to MET dependent cell lines. The pattern of activity was related to MET inhibition and downstream signaling inhibition of AKT and ERK1/2, resulting in G0/G1 cycle arrest and apoptosis. In contrast, tivantinib possessed more potent anti-proliferative activity that was not restricted to only MET dependent cell lines. Tivantinib did not inhibit cellular MET activity or phosphorylation of downstream signaling proteins AKT or ERK1/2 in either MET dependent or independent cell lines. Cell cycle analysis demonstrated that tivantinib induced a G2/M arrest and induced apoptosis. Tivantinib but not crizotinib effected microtubule dynamics, disrupting mitotic spindles by a mechanism consistent with it functioning as a microtubule depolymerizer. Tivantinib activity is independent of MET signaling in NSCLC and suggests alternative mechanisms of action that should be considered when interpreting the results from on-going clinical studies.

A Novel Mechanism of Alternative Promoter and Splicing Regulates the Epitope Generation of Tumor Antigen CML66-L (2004)

This report describes the difference in the epitope generation of two isoforms of self-tumor Ag CML66 and the regulation mechanism. We identified a new CML66 short isoform, termed CML66-S. The previously identified long CML66 is referred to as CML66-L. CML66-S shares the C terminus with CML66-L but has its unique N terminus. CML66-S is predominantly expressed in testis, but is also expressed in very low levels in tumor cells, whereas CML66-L is expressed in tumor cells and testis. Differential expression of CML66-L and CML66-S in tumor cells resulted from regulation at transcription, although alternative splicing also participated in the generation of the isoforms. In addition, Ab titers to a CML66-L peptide were significantly higher than that to CML66-S peptide in the sera from patients with tumors. Finally, the Abs to full-length CML66-L in the sera from patients with tumors were correlated with the Abs in the sera from these patients to CML66-L-38, which is a fusion protein with a CML66-L-specific N terminus. This suggests that the CML66-L isoform is mainly responsible for the epitope generation. Our studies have identified the alternative promoter in combination with alternative splicing as a novel mechanism for regulation of the epitope generation of a self-tumor Ag.
Privacy-Preserving Matching of DNA Profiles. (2008)

In the last years, DNA sequencing techniques have advanced to the point that DNA identification and paternity testing has become almost a commodity. Due to the critical nature of DNA related data, this causes substantial privacy issues. In this paper, we introduce cryptographic privacy enhancing protocols that allow to perform the most common DNAbased identity, paternity and ancestry tests and thus implement privacy-enhanced online genealogy services or research projects. In the semi-honest attacker model, the protocols guarantee that no sensitive information about the involved DNA is exposed, and are resilient against common forms of measurement errors during DNA sequencing. The protocols are practical and efficient, both in terms of communication and computation complexity. 1
A rapid co-culture stamping device for studying intercellular communication (2016)

Regulation of tissue development and repair depends on communication between neighbouring cells. Recent advances in cell micro-contact printing and microfluidics have facilitated the in-vitro study of homotypic and heterotypic cell-cell interaction. Nonetheless, these techniques are still complicated to perform and as a result, are seldom used by biologists. We report here development of a temporarily sealed microfluidic stamping device which utilizes a novel valve design for patterning two adherent cell lines with well-defined interlacing configurations to study cell-cell interactions. We demonstrate post-stamping cell viability of >95%, the stamping of multiple adherent cell types, and the ability to control the seeded cell density. We also show viability, proliferation and migration of cultured cells, enabling analysis of co-culture boundary conditions on cell fate. We also developed an in-vitro model of endothelial and cardiac stem cell interactions, which are thought to regulate coronary repair after myocardial injury. The stamp is fabricated using microfabrication techniques, is operated with a lab pipettor and uses very low reagent volumes of 20 μl with cell injection efficiency of >70%. This easy-to-use device provides a general strategy for micro-patterning of multiple cell types and will be important for studying cell-cell interactions in a multitude of applications.
Correlation length of ultrasonic speckle in anisotropic random media: Application to coherent echo detection (1998)

In a recent paper [Derode and Fink, J. Acoust. Soc. Am. 101, 690–704 (1997)], a technique for studying spatial coherence properties of backscattered speckle noise by means of a transducers array was described. In this paper another approach is presented. Here, a single transducer, focusing inside a scattering medium, is moved in a plane; correlation is studied between signals acquired in two different positions. A study investigates how the correlation function of the medium determines that of the speckle noise. This is applied to fully or partially incoherent media, and media with anisotropic scatterer distribution such as unidirectional and cross-ply composites; we show that it is possible to extract information about the medium from a measurement of the backscattered field correlation length. The influence of correlation length on defect detection is discussed. Experimental as well as theoretical results are presented, they are found in good agreement.

Terpenes from Eunicea Laciniata and Plexaurella Nutans (2006)

A new 7,8–epoxydolabella–3(E)–12(18)–diene (1), diterpenoid together with three known compounds were isolated from a Honduras gorgonian Eunicea laciniata. The relative stereochemistry of 1 was established by spectroscopic studies and the antiprotozoal and antimicrobial activities of dolabellane diterpenoids 2–4 are reported. Three known cadinane type sesquiterpenes were also isolated from Honduras gorgonian Plexaurella nutans.
Ten‐year experience of recombinant activated factor VII use in surgical patients with congenital haemophilia with inhibitors or acquired haemophilia in Japan (2014)

Patients with congenital haemophilia with inhibitors or acquired haemophilia are at risk of bleeding complications during surgery. In these patients, replacement therapy for the missing coagulation factor is ineffective, and a bypassing agent such as recombinant activated factor VII (rFVIIa) is required to manage bleeding. To evaluate the safety and haemostatic efficacy of rFVIIa treatment in Japanese patients with congenital haemophilia with inhibitors to FVIII/FIX or acquired haemophilia undergoing surgery. Postmarketing surveillance data from May 2000 to March 2010 were analysed to assess the haemostatic efficacy of 38 procedures in 22 patients with congenital haemophilia A, 13 procedures in seven patients with congenital haemophilia B, and five procedures in five patients with acquired haemophilia. Postoperative bleeding control was judged to be effective (bleeding was stopped completely or reduced considerably) for 34/38 procedures (89%) in patients with congenital haemophilia A, 10/13 procedures (77%) in patients with congenital haemophilia B, and 4/5 procedures (80%) in patients with acquired haemophilia. Tranexamic acid was used concomitantly for 36/56 procedures (64%). Safety was analysed for 66 procedures in 37 patients. Adverse effects potentially related to rFVIIa treatment included mild superficial thrombophlebitis, mild decrease in platelet count, and mild elevation of the serum alanine transaminase level in one patient each. All adverse effects resolved without treatment. Administration of rFVIIa provided adequate haemostasis without serious adverse effects in the majority of cases. The efficacy and safety data in Japanese patients were similar to previously published data from other countries.
