H204M — watermarking for media (2000)

Security has become one of the most significant problems for spreading new information technology. Beside cryptographic solutions digital watermarking methods offer several protection possibilities. H204M — Watermarking for Media is a joined project at GMD-IPSI (German National Research Center for Information Technology) and the German broadcast archive DRA funded by the German government to classify, evaluate and improve digital watermarking techniques. Today a wide variety of techniques has been proposed but it is quite difficult to classify the approaches and measure their quality. Our intention in this project is to discuss the main watermarking parameter and to present a media independent classification scheme as a basis for quality evaluation. Furthermore one outstanding goal of the project is practical testing of existing techniques in a real scenario at the DRA with the content-management provider tecmath AG. Practical experiences are an essential basis for better design approaches. To date, such integration of watermarking algorithm into content management systems are not evaluated. In parallel a group was established initiated by Fabien Petitcolas to offer a public automated watermarking evaluation service: StirMark Benchmark. In our paper we present the H204M project scenario, first results of the media-independent classification scheme and the StirMark Benchmark evaluation service.
Adaptive Educational Gameplay within Smart Multipurpose Interactive Learning Environment (2007)

Modern technologies have brought many innovations into the system of education. Learners now have an opportunity to educate with the help of electronic materials often provided by web-based infrastructures. Although the majority of learners - especially children or teenagers - find studying from such materials less exciting than playing today's popular computer games that, however, lack signs of education. In this paper, we describe an innovative concept of three-dimensional interactive educational games that combine the excitement and looks of popular computer games with the educational potential of electronic study materials. One of the key issues is adaptability (games are also playable by handicapped users) and adaptivity according to learners' level of knowledge. Together with automatic generation of educational games based on metadata provided by authors of educational materials, we enable the creation of educational games that have many shapes reflecting learners' needs.
Fundamentals of Enzymology: The Cell and Molecular Biology of Catalytic Proteins (1999)

Since the publication of the second edition of Fundamentals of Enzymology in 1989 there has been a large increase in the knowledge of several aspects of enzymology, not least the rapid acceleration of structural characterization of enzymes and the development of the field of bioinformatics. This edition places appropriate emphasis on this knowledge and consolidates the strengths of the previous editions. As before, the book gives an all-round view of the field including enzyme purification and characterization, enzyme structure (including information on World Wide Web sites), enzyme kinetics, the mechanisms and control of enzyme action, enzyme folding, how enzymes act in vivo, enzyme synthesis and degradation, and also clinical and industrial applications of enzymology. Throughout the book, the integration of these themes is stressed. This book is intended for second or third (fourth in Scotland) year undergraduates on biochemistry/molecular biology courses.
Guided tour of handoff steering for bandwidth in indoor venues (2015)

With the advancement and development for more than two decades, WiFi has become an indispensable infrastructure in most of indoor venues. Indoor localization using this pre-existing infrastructure has been studied in the literature and is proven practically feasible, which mostly relies on WiFi fingerprints and the corresponding radiomap database. Since the radiomap essentially tells which APs are available and how strong their signals are at positions in the venue, this information can usefully utilized to “steer” to a better AP for the purpose of increasing the user throughput, which we call Guided Tour of Handoff Steering (GUT) in this paper. This steering is not much different from a conventional handoff, but it does not need an expensive scanning process owing to the radiomap, thus some additional handoffs are allowed than conventional handoffs. This leads to higher throughput, because a client can switch to a better AP whenever available. Based on an extensive experiment in a large-scale indoor venue of 119,685m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> with 1,734 APs, it is observed that GUT achieves as much as 84% higher throughput, but the number of handoffs increases only a few. This result supports that the handoff steering is not as expensive as the conventional handoff in terms of latency and traffic.

Revista Horizontes: prensa y sociedad en la Guayana del siglo XIX (2010)

El presente estudio pretende determinar la funcion social de las publicaciones periodicas en la Guayana del siglo XIX, mostrando el sistema de valores que se tenia con respecto a las mismas y analizando a su vez a la prensa como un texto que se interrelaciona con los demas componentes de su contexto social y cultural, colocando el enfasis en las tres unidades fundamentales de toda historia de la comunicacion: autor, obra, lector. Asi, la revista Horizontes (1899-1914), organo del Centro Cientifico Literario de Ciudad Bolivar, revista cultural de mayor importancia en la region, llamada en su momento �El Cojo Ilustrado de Guayana�, nos permitira acercarnos a las practicas culturales del siglo XIX en relacion con la caracterizacion de sus generos (revistas), tipos (intelectuales) e instituciones (centros literarios), intentando hacer una �pintura viva� de la dinamica cultural guayanesa y su relacion con las practicas culturales nacionales y continentales. Asi, el fin ultimo y general de la siguiente investigacion es desentranar las intimas relaciones que existen entre la comunicacion y el desarrollo social
Sorting by hashing and inserting (1989)

Address calculation sorting method is discussed by Kronmal & Tartar (Proc. ACM Nat'l Conf 21). Generally collision resolution is done by chaining, where the records are inserted in ordered linked lists with heads defined as array of pointers. Then the linked lists are merged in the original array. For uniformly distributed lists and careful choice of a hash function the algorithm works quite efficiently and is faster than other sorting methods. Our comparisons show that the algorithm works more than twice as fast as Quick Sort. The disadvantage with this method is that it needs extra space for 2N records. Also it is not an in place sort.
Effects of moisture on thermal and mechanical properties of nylon‐6,6 (1989)

Abstract This study examined the moisture absorption and other properties of nylon‐6,6 as a function of mold temperature and annealing effects. Moisture absorption was seen to decrease as the temperature of molding and annealing increased with a predictable effect on mechanical and thermal properties: namely, increased moisture absorption indicated lower strength, stiffness, but higher ductility and impact resistance. Thermal analysis by differential scanning calorimetry indicated that with an increase in moisture absorption in the nylon‐6,6 a broadening of the melting endotherm is observed, suggesting a typical plasticizing effect of water on the nylon‐6,6. This study suggests that molding conditions of a nylon‐6,6 material may ultimately effect the levels of crystallinity in the final part and establish a relationship between the amount of absorbed water for a given nylon product and its processing variables.
Hierarchical Schemes for Adaptive Routing and Flow Control in Large Computer Networks (1983)

Recent advances in the general theory of multivariable and large-scale systems have contributed to the development of hierarchical control schemes where the overall decision-making task is distributed over a number of hierarchical levels. Use of such a hierarchical framework for the design of control schemes at the transport level in large computer communication networks can result in several beneficial features such as information aggregation for reduction in data storage requirements, capability of handling multiple objective functions in performance optimization, better adaptivity to variations in load and network topology and possibility of integrating routing and flow control functions for a more efficient control of traffic congestion. This paper outlines the development of two hierarchical schemes for routing and flow control that have recently been developed within such a framework.
Treatment of cats with ocular disease attributable to herpesvirus infection: 17 cases (1983–1993) (1995)

Medical records of 17 cats with ocular disease attributable to herpesvirus injection were reviewed. Herpesvirus infection was confirmed by a positive result on an immunofluorescent antibody test or by detection of dendritic corneal ulcers. Cats were 3 months to 23 years old (mean, 4.8 years). Sex or breed predilections were not evident. Vaccination history was available for 13 cats, 9 of which had been adequately vaccinated against feline viral rhinotracheitis, calici, and panleukopenia viruses. Six cats had a history of respiratory tract disease. Twelve cats were tested for FeLV, and 3 had positive results; 7 cats were tested for feline immunodeficiency virus, with 1 positive result. The most common ocular abnormality seen was conjunctivitis (13/17 cats), followed by dendritic corneal ulcers (10/17 cats). Keratitis was detected in 6 of 17 cats, and nondendritic corneal ulcers in 3 of 17 cats. Corneal sequestra were evident on initial examination or developed during the follow-up period in 4 of 17 cats. Keratoconjunctivitis sicca was diagnosed in 2 of 17 cats, and anterior uveitis was evident in 1 of 17 cats. All cats had 2 or more clinical ocular abnormalities associated with herpesvirus infection. Treatment with topically applied antiviral medications was instituted in 14 cats, including idoxuridine in 7, vidarabine in 4, and trifluridine in 3. Antibiotics were used topically in 10 cats, and atropine was used in 3 cats. Topical administration of corticosteroids was used in 2 cats. Recombinant human alpha-interferon was given orally to 3 cats in conjunction with topical administration of antiviral agents. In addition to medical treatment, 4 cats were treated surgically.(ABSTRACT TRUNCATED AT 250 WORDS)
Aesthetic and auditory enhancements for multi-stream information sonification (2008)

Sonification is an emerging modality of information representation, the auditory equivalent of visualization employing non-speech sound to display attributes of form, pattern, recurrence and trends in abstract data. Like data-art or visual and auditory art-forms driven by data content directly mapped to their rendering, sonification shares the goal of aesthetic representation (auditory graphing) in a way to better and more accessibly convey the message to broader consumer audiences. Often, the simple re-contextualization of dense abstract data in an auditory graph (or sonification) is sufficient to highlight long-term trends, to hear regularities (patterns) and anomalies in periodicity of time-series data and to assimilate very subtle and fine transformations. Sonification is also optimal for certain working or ambient situations that are visually rich or visually saturated, when we seek to command topical and peripheral attention with relevant cues. Auditory display is also an alternative to visualization for people with visual impairments. Exploring the premise that sonification should be both aesthetic and informative, i.e. listenable, attractive and engaging, this paper summarises the findings of 3 experiments conducted to determine ways to better represent and access dense information mapped on to more than one concurrent stream of information. Specifically, we show evidence that spatialization of informative events coinciding in time can be more clearly distinguished and that timbre (or tone colour / tone quality) characteristics can serve to further reinforce spatial and stream separation. These findings combine to develop comprehensible methods for representing complex data-sets. We consider human cognition, auditory perception and audio reproduction technologies that each influence the ability to display information sonically.
Improved acoustic modeling with the SPHINX speech recognition system (1991)

The authors report recent efforts to further improve the performance of the SPHINX system for speaker-independent continuous speech recognition. They adhere to the basic architecture of the SPHINX system and use the DARPA resource management task and training corpus. The improvements are evaluated on the 600 sentences that comprise the DARPA February and October 1989 test sets. Several techniques that substantially reduced SPHINX's error rate are presented. These techniques include dynamic features, semicontinuous hidden Markov models, speaker clustering, and the shared distribution modeling. The error rate of the baseline system was reduced by 45%.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Evaluation of biomatrix hydroxyapatite ocular implants with technetium-99m-MDP. (1993)

Hydroxyapatite ocular implants appear to offer excellent cosmetic reconstruction with lower rates of infection and extrusion compared to other integrated implants. However, vascularization of the implant needs to be established before the artificial eye is attached to the implant. Technetium-99m-methylene diphosphonate (MDP) scintigraphy can be utilized as a noninvasive method for determining the vascularity of the hydroxyapatite ocular implants. A case is presented in which 99mTc-MDP uptake in the implant was deemed sufficient for further surgical intervention.
Group of Targets Recognition Method in Battlefield Based on Cluster Thought (2007)

To meet the fast decision-making of modern warfare,an algorithm for group of targets recognition in battlefield is proposed,which is based on cluster thought.By cluster method of dissimilarity analysis,this algorithm makes use of the characteristic measure of location,speed and direction of targets to recognize groups of targets in battlefield.The advantage of the algorithm is its low complexity,much higher recognition accuracy rate and much more robust handling for outlier.The algorithm can satisfy the real time requirement in battlefield.Simulation experiments demonstrate that the algorithm can accurately recognize the group of targets in battlefield with higher probability and provide direct support for fast decision-making of battle and programming of tactics.

A dual source photon beam model used in convolution/superposition dose calculations for clinical megavoltage x‐ray beams (1997)

A realistic model of photon beams generated by clinical linear accelerators has been incorporated in a convolution/superposition method to compute dose distributions in photon treatment fields. In this beam model, a primary photon source represents photons directly from the target, and an extra-focal photon source represents scattered photons from the primary collimator and the flattening filter. Monte Carlo simulation was used to study clinical linear accelerators producing photon beams. From the output of the Monte Carlo simulation, the fluence and spectral distributions of each photon component, as well as the geometrical characteristics of each photon source with respect to its distance to the isocenter and its source distribution, were analyzed. These quantities were used to reproduce realistic photon distributions in treatment fields, and thus to compute dose distributions using the convolution method. Our results showed that compared to the primary photon fluence, the extra-focal photon fluence from the primary collimator and the flattening filter was 11%-16% at the isocenter, among which 70% was contributed by the flattening filter. The variation of extra-focal photons in different treatment fields was predicted accurately by accounting for the finite size of the extra-focal source. Compared to measurements, dose distributions in photon treatment fields, including those of asymmetric jaw settings and at different SSDs were calculated accurately, particularly in the penumbral region, by using the convolution method with the new dual source photon beam model.
A Novel Signaling Axis of Matriptase/PDGF-D/β-PDGFR in Human Prostate Cancer (2010)

Increasing evidence indicates the significance of platelet-derived growth factor receptor-β (β-PDGFR) signaling in prostate cancer (PCa). Accordingly, preclinical studies suggest the potential of β-PDGFR as a therapeutic target in metastatic PCa. However, a ligand responsible for β-PDGFR activation in PCa was unknown, and recent clinical trials with imatinib mesylate showed limited success due to normal tissue toxicity. Similarly, in spite of mounting evidence indicating the significance of matriptase in PCa, little is known about its substrates or molecular actions during PCa progression. Here, we identified PDGF-D as a ligand for β-PDGFR in PCa and discovered matriptase as its regulator. Matriptase activates PDGF-D by proteolytic removal of the CUB domain in a 2-step process, creating a hemidimer, followed by growth factor domain dimer (GFD-D) generation. Matriptase can deactivate PDGF-D by further proteolytic cleavage within the GFD, revealing its biphasic regulation. Importantly, PDGF-D/matriptase colocalization is accompanied with β-PDGFR phosphorylation in human PCa tissues. This study unveiled a novel signaling axis of matriptase/PDGF-D/β-PDGFR in PCa, providing new insights into functional interplay between serine protease and growth factor signaling networks.
α‐Fe<sub>2</sub>O<sub>3</sub> Nanotubes in Gas Sensor and Lithium‐Ion Battery Applications (2005)

Templated arrays of α-Fe2O3 nanotubes, produced using an alumina membrane, exhibit enhanced sensitivity to ethanol and hydrogen as well as enhanced electrochemical activity in lithium-ion batteries. The nanotubes, characterized by uniform size and shape (see Figure), possess a high specific surface area, leading to electrochemical activities much higher than that of bulk or nanoparticulate α-Fe2O3.
Ternary Organic Solar Cells Based on a Wide-Bandgap Polymer with Enhanced Power Conversion Efficiencies (2019)

A low-bandgap acceptor (ITIC) was added to a binary system composed of a wide-bandgap polymer (PBT-OTT) and an acceptor (PC<sub>71</sub>BM) to increase the light harvesting efficiency of the associated organic solar cells (OSCs). A ternary blend OSC with an acceptor ratio of PC<sub>71</sub>BM:ITIC = 8:2 was found to exhibit a power conversion efficiency of 8.18%, which is 18% higher than that of the binary OSC without ITIC. This improvement is mainly due to the enhanced light absorption and optimized film morphology that result from ITIC addition. Furthermore, an energy level cascade forms in the blend that ensures efficient charge transfer, and bimolecular and trap-assisted recombination is suppressed. Thus the use of ternary blend systems provides an effective strategy for the development of efficient single-junction OSCs.
ARC-1779, a PEGylated aptamer antagonist of von Willebrand factor for potential use as an anticoagulant or antithrombotic agent. (2009)

Archemix Corp's ARC-1779 is an optimized, second-generation, PEGylated aptamer that exerts a novel antithrombotic action through targeting the A1 domain of activated von Willebrand factor (vWF) and inhibiting the binding of platelet receptor glycoprotein Ib, thus reducing platelet adhesion, aggregation and thrombus growth in arterial beds. By inhibiting vWF-dependent arterial thrombogenesis, ARC-1779 has potential therapeutic benefit in acute coronary syndromes and von Willebrand's disease, as well as in vWF-related platelet disorders such as thrombotic thrombocytopenic purpura (TTP) and other thrombotic microangiopathies. As an aptamer, the actions of ARC-1779, unlike other antiplatelet agents, can be readily reversed by binding to a complementary sequence of oligonucleotides; this ability offers potential therapeutic benefit in surgery. In phase I and II clinical trials, ARC-1779 has exhibited favorable pharmacokinetic, pharmacodynamic and safety properties in healthy individuals and patients with TTP. At the time of publication, phase II trials in patients with TTP and thrombosis were ongoing or recruiting patients. Further phase II and III trials are necessary and highly anticipated to establish the therapeutic potential of ARC-1779 as an antithrombotic agent.
Requirements-based testing of real-time systems: Modeling for testability (1985)

Requirements validation depends largely on the techniques used for specification, so the augmented finite-state machine (FSM) model used to capture the external behavior of a real-time system is central to the environment. Therefore, this paper describes the validation techniques used and explores those aspects of the specification model that facilitate test generation and execution using the behavioral description. We refer to this theme as requirements modeling for testability. Our thesis is: although an FSM or an augmented FSM may be relatively limited in its ability to capture the whole range of practical systems' behaviors, it is adequate for real-time systems in which sequential computations dominate. The FSM model should be preferred for applications in which high reliability is a primary concern; expressive power can be traded off to ensure quality.
Assessment of athletic health care facility surfaces for MRSA in the secondary school setting. (2010)

Methicillin-resistant Staphylococcus aureus (MRSA) was once largely a hospital-acquired infection, but increasingly, community-associated MRSA (CA-MRSA) is causing outbreaks among otherwise healthy people in athletic settings. Secondary school athletic trainers, student athletes, and the general student population may be at elevated risk of MRSA infection. To identify the prevalence of MRSA on surfaces in high school athletic training settings, 10 rural high school athletic training facilities and locker rooms were sampled for MRSA. Results showed 90% of facilities had two or more positive MRSA surfaces, while one school had no recoverable MRSA colonies. Of all surfaces tested (N=90), 46.7% produced a positive result. From this limited sample, it is evident that significant exposure opportunities to MRSA exist in athletic training clinics and adjacent facilities for both the patient and the clinician. Furthermore, the findings point to the need for community hygiene education about skin and soft tissue infections like MRSA.
