Smart Contract Negotiation in Cloud Computing (2017)

A smart contract is the formalisation of an agreement, whose terms are automatically enforced by relying on a transaction protocol, while minimising the need of intermediaries. Such contracts not only specify the service and its quality but also the possible changes at runtime of the terms of agreement. Although smart contracts provide a great deal of flexibility, analysing their compatibility and reaching agreements with this level of dynamism is considerably more challenging, due to the freedom of clients and providers in formulating needs/offers. We introduce a formal language to specify interactions between offers and requests and present a methodology for the autonomous negotiation of smart contracts, which analyses the cost and the necessary changes for reaching an agreement. Moreover, we describe a set of experiments that provides insights on the relative cost of dynamism in negotiating smart contracts and compare the request/offer matching rates of our solution with related works.
Destination Prediction by Trajectory Distribution-Based Model (2017)

In this paper, we propose a new method to predict the final destination of vehicle trips based on their initial partial trajectories. We first review how we obtained clustering of trajectories that describes user behavior. Then, we explain how we model main traffic flow patterns by a mixture of 2-D Gaussian distributions. This yielded a density-based clustering of locations, which produces a data driven grid of similar points within each pattern. We present how this model can be used to predict the final destination of a new trajectory based on their first locations using a two-step procedure: we first assign the new trajectory to the clusters it most likely belongs. Second, we use characteristics from trajectories inside these clusters to predict the final destination. Finally, we present experimental results of our methods for classification of trajectories and final destination prediction on data sets of timestamped GPS-Location of taxi trips. We test our methods on two different data sets, to assess the capacity of our method to adapt automatically to different subsets.

The program and its source code were made available as open-source software on the internet.
Wide-Wavelength InGaAs/InP PIN Photodiodes Sensitive From 0.7 To 1.55 um (1989)

We have demonstrated for the first time a wide-wavelength InGaAs/InP PIN photodiode for optical communication systems working area the 0.7 to 1.55 um wavelength region. The diode has a planar structure with InP/InGaAs/InP double-hetero epitaxial wafer grown by chloride VPE. To obtain high-sensitivity to 0.7 um wavelength light, it has a very thin InP cap layer (0.06 um) and a shallow p-n junction (0.27 um) is formed in the InGaAs layer. Quantum efficiencies for 0.78 um and 1.3 um wavelengths are 76% and 81%, respectively. Dark current and capacitance are as low as 30 pA and 0.53 pF at 5V. Frequency response is flat up to 1 GHz over 5V at 0.78 um.
Improved multistage decoding of multilevel codes for digital radio mondiale (drm) (2005)

The new digital radio standard Digital Radio Mondiale (DRM) uses multilevel coding as channel coding. A very effective decoding algorithm is the iterative multi- stage decoder (MSD). In our paper we analyze different implementations of the MSD utilizing hard-decision with different metrics. The performance of these implementa- tions is evaluated by computer simulations. Additionally, an MSD with soft-decision (Max-Log-MAP) is investigated and serves as a benchmark for the hard-decision algorithms.
Galaxy M 31 (1964)

In his report "Radio map of the Andromeda galaxy" (24 July, p. 389), John M. MacLeod reported the results of observing the nearby galaxy M 31 with the new University of Illinois radio telescope. At about the same time a paper of mine appeared in the Astrophysical Journal (139, p. 1045) analyzing the spiral structure of M 31. Putting the results of the two investigations together now reveals an unexpected and intriguing puzzle.
Modulating Mucin Hydration and Lubrication by Deglycosylation and Polyethylene Glycol Binding (2015)

A key property of mucin glycoproteins is their exceptional capacity to hydrate and lubricate surfaces. In vivo, mucins assemble into mucus hydrogels that cover the epithelium and protect it from dehydration and shear stress. A better understanding of the origin of these properties could lead to new treatment strategies for patients with poor mucus coverage, defective mucus production, or glycosylation as caused by Sjögren syndrome, dry eye, or in the case of certain bacterial infections. In this work, mucin coatings are used to show that mucin‐associated glycans are essential for the formation of such hydrated and lubricating layers. Native mucins are compared with deglycosylated mucins by analyzing their hydration and it is shown that their lubricative potential in the boundary and mixed lubrication regime is linked to the hydration. The removal of glycans from the mucin results in a 3.5‐fold decrease in hydration and an increase in friction by two orders of magnitude. This loss of function is countered by grafting polyethylene glycol (PEG) molecules to defective mucins through lectin–glycan interactions. This lectin‐PEG conjugation restores hydration and improves lubrication of the partially deglycosylated mucin coatings. Thus, local complementation of defective mucus layers could prove to be a useful new treatment strategy.
Mode of Action and Biochemical Characterization of REP8839, a Novel Inhibitor of Methionyl-tRNA Synthetase (2005)

Aminoacyl-tRNA synthetases have attracted interest as essential and novel targets involved in bacterial protein synthesis. REP8839 is a potent inhibitor of MetS, the methionyl-tRNA synthetase in Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA), and in Streptococcus pyogenes. The biochemical activity of REP8839 was shown by specific inhibition of purified S. aureus MetS (50% inhibitory concentration, <1.9 nM). Target specificity was confirmed by overexpression of the metS gene in S. aureus, resulting in an eightfold increase in the MIC for REP8839. Macromolecular synthesis assays in the presence of REP8839 demonstrated a dose-dependent inhibition of protein synthesis and RNA synthesis in S. pneumoniae R6, but only protein synthesis was affected in an isogenic rel mutant deficient in the stringent response. Strains with reduced susceptibility to REP8839 were generated by selection of strains with spontaneous mutations and through serial passages. Point mutations within the metS gene were mapped, leading to a total of 23 different amino acid substitutions within MetS that were located around the modeled active site. The most frequent MetS mutations were I57N, leading to a shift in the MIC from 0.06 microg/ml to 4 microg/ml, and G54S, resulting in a MIC of 32 microg/ml that was associated with a reduced growth rate. The mutation prevention concentration was 32 microg/ml in four S. aureus strains (methicillin-sensitive S. aureus and MRSA), which is well below the drug concentration of 2% (20,000 microg/ml) in a topical formulation. In conclusion, we demonstrate by biochemical, physiologic, and genetic mode-of-action studies that REP8839 exerts its antibacterial activity through specific inhibition of MetS, a novel target.
Fast, accurate power measurement and optimization for microprocessor platforms (2015)

Power and energy consumption have become important for all computers, but the tools used to measure and optimize power on physical hardware lag far behind performance focused tools. Existing measurement apparata have low analog bandwidth, do not explicitly correlate power data with processor activity, and are not explained in sufficient detail to quantify uncertainty in their data. We present the design, implementation, and application of Jouler’s Loupe, a measurement device that overcomes these obstacles and enables a new generation of fast, fundamentally sound energy-efficiency-focused tools. We demonstrate substantial opportunity for energy-focused software optimizations on a mobile CPU core.
EnVision: A Web-Based Tool for Scientific Visualization (2009)

Scientific visualization is the process of transforming raw numeric data into a visual form, and is a key element of computational science. While many tools exist, they are unnecessarily difficult to use. This complexity increases time to insight and inhibits casual inquiry. The complexity derives from the need to support arbitrarily formatted data and many visualization algorithms. EnVision addresses both sources of complexity. Its design is predicated on two key insights. First, though the number of data file formats is unbounded, the structure of any one can be described using a small number of parameters. Second, the set of visualization algorithms applicable to a given type of data is small, and the subset used within a specific scientific discipline is smaller. EnVision utilizes domain-specific knowledge and user-directed semi-automation to dramatically simplify data importation and visualization algorithm selection. Its Web-based interface facilitates access to remote hardware resources and provides a collaborative visualization environment.
Learning to Predict Ego-Vehicle Poses for Sampling-Based Nonholonomic Motion Planning (2018)

Sampling-based motion planning is an effective tool to compute safe trajectories for automated vehicles in complex environments. However, a fast convergence to the optimal solution can only be ensured with the use of problem-specific sampling distributions. Due to the large variety of driving situations within the context of automated driving, it is very challenging to manually design such distributions. This paper introduces therefore a data-driven approach utilizing a deep convolutional neural network (CNN): Given the current driving situation, future ego-vehicle poses can be directly generated from the output of the CNN allowing to guide the motion planner efficiently towards the optimal solution. A benchmark highlights that the CNN predicts future vehicle poses with a higher accuracy compared to uniform sampling and a state-of-the-art A*-based approach. Combining this CNN-guided sampling with the motion planner Bidirectional RRT* reduces the computation time by up to an order of magnitude and yields a faster convergence to a lower cost as well as a success rate of 100 % in the tested scenarios.
Flexibility and phase transitions of polymers (2003)

Abstract It is shown, that both the mobility of polymers as well their transition temperatures (glass transition and crystallization) depend on the “flexibility” of simple bonds, i.e., on their ability to promote by energetically stimulated rotations conformational changes to release stresses. The polymer class specific interdependence between melting temperature, T m and glass temperature, T g , suggests that the “flexibility” of polymers depends additionally on the probability of interactions between sequences of polymer chains. Interaction between polymer chain sequences controls at the same time the ordering necessary for crystallization. Characteristic of polymers is thus the dependence of both transition temperatures on the “mass/'flexible bond” of the monomeric (repeating) unit, μ/ρ. This experimentally observed polymer class specific behavior is reflecting the similar probabilities of interaction within a given class of polymers. © 2003 Wiley Periodicals, Inc.

Perforating collagenosis (2008)

A 55-year-old man presented with a three-week history of pruritic, erythematous papules with hyperkeratotic dells on the dorsum of the left hand, which was preceded by swelling, redness and itching. Histopathologic examination showed an acanthotic epidermis with a central invagination filled with a plug composed of parakeratotic debris, collagen, and inflammatory cells. These findings are consistent with acquired reactive perforating collagenosis, which is most frequently reported in patients with pruritus and underlying diabetes mellitus or chronic renal insufficiency. Topical and oral retinoids and topical and intralesional glucocorticoids have been reported to be effective in some patients in case series.

Devonian Gametophytes with Anatomically Preserved Gametangia (1980)

The oldest anatomically preserved and physiologically apparently independent gametophytes are described from the Lower Devonian of Scotland. These gametophytes have upright, leafless axes with terminally borne, bowl-shaped game-tangiophores. The antheridia are stalked and their walls are multicellular. The archegonia are clustered in groups on common bases.
Fuzzy-junction organic light-emitting devices (2002)

A “fuzzy-junction” organic light-emitting device (OLED) containing a graded organic–organic interface is reported. Such graded junction is effectively produced utilizing interdiffusion through an ultrathin interfacial fusing layer sandwiched between two functional layers. With a glass transition temperature (Tg) lower than remaining layers, this fusing layer permits smooth interdiffusion and mixing of neighboring layers by annealing above its Tg. With appropriate material combinations, fuzzy-junction OLEDs thus prepared exhibit both reduced voltage and enhanced emission efficiency in comparison with conventional abrupt-junction devices. As an instance, a green fluorescent OLED with such fuzzy junction shows a high peak power efficiency of ∼20 lm/W, substantially higher than ∼14 lm/W of a corresponding abrupt-junction device.
Prefetching techniques for STT-RAM based last-level cache in CMP systems (2014)

Prefetching is widely used in modern computer systems to mitigate the impact of long memory access latency by paying extra cost in memory and cache accesses. However, the efficacy of prefetching significantly degrades in the memory hierarchy using the emerging spin-transfer torque random access memory (STT-RAM) as last-level cache (LLC) due to the long write access latency. In this work, we propose two orthogonal but complimentary techniques to improve the prefetching efficacy of STT-RAM based LLC in chip multi-processor (CMP) systems, namely, request prioritization (RP) and hybrid local-global prefetch control (HLGPC). Simulation results show that by combining these two techniques, we can achieve 6.5%~11% system performance improvement and 4.8%~7.3% LLC energy saving in a quadcore system with a 2MB~8MB STT-RAM based LLC, compared to the system with only basic prefetching.
Wavelength dependent reflectance functions (1994)

A wavelength based bidirectional reflectance function is developed for use in realistic image synthesis. A geodesic sphere is employed to represent the BRDF, and a novel data structure is used to store this description and to recall it for rendering purposes. A virtual goniospectrophotometer is implemented by using a Monte Carlo ray tracer to cast rays into a surface. An optics model that incorporates phase is used in the ray tracer to simulate interference effects. An adaptive subdivision technique is applied to elaborate the data structure from rays scattered into the hemisphere above the surface. The wavelength based BRDF and virtual goniospectrophotometer are utilized to analyze and make pictures of thin films, idealized pigmented materials, and pearlescent paints.
Growth Mode of Copper Films Electrodeposited on Silicon from Sulfate and Pyrophosphate Solutions (1999)

The electrodeposition of thin copper films on silicon substrates from copper pyrophosphate and copper sulfate solutions, without the addition of additives or hydrofluoric acid, is presented. The copper films obtained from these two solutions have different characteristics. Cyclic voltammetry was performed in order to investigate the silicon/electrolyte interface. This provides an explanation why the copper pyrophosphate solution is more favorable for electrodepositing copper on a semiconductor substrate. The copper films obtained with the pyrophosphate solution, having thicknesses ranging from 20 to 280 nm, were characterized in detail. They are homogeneous, exhibit a metallic luster, and show good adhesion. The topography was examined by atomic force microscopy, providing the root-mean-square roughness and the average grain size on the surface. The grain size values are compared with the average value of the scattering coherence length determined by X-ray diffraction. The kinetic roughening of the copper deposits was investigated by dynamic scaling behavior and compared to previous studies. (C) 1999 The Electrochemical Society. S0013-4651(98)08-028-8.

Digallic acid from <i>Pistascia lentiscus</i> fruits induces apoptosis and enhances antioxidant activities (2011)

The antioxidant and apoptotic activities of digallic acid, isolated from the fruits of Pistascia lentiscus, were investigated. The study demonstrated that digallic acid possessed pro-apoptotic effects, as shown by provoking DNA fragmentation of K562 cells. It also revealed a significant antioxidant potential and effective scavenging activity against 2,2-diphenyl-1-picrylhdrazyl (DPPH·) and O₂·⁻ radicals, and reduced cupric ions. We conclude that this integrated approach to apoptotic and antioxidant assessment may be useful to maximize the beneficial effects associated with using P. lentiscus derivatives as medicinal and dietary compounds.
Silicon incorporation into chemical vapor deposition diamond: A role of oxygen (1997)

The suppression effect of oxygen on Si incorporation in homoepitaxial diamond films grown by microwave assisted chemical vapor deposition is investigated by secondary ion mass spectrometry. The Si depth profile in the multilayered diamond films continuously synthesized with different oxygen addition shows that Si incorporation decreases with increasing oxygen addition into the plasma. A change in the interfacial composition at the quartz glass due to oxygen-promoted surface chemistry may be the origin of this suppression effect.
Quality management manual for the production of high quality cassava flour (2006)

The high quality cassava flour (HQCF) industry has just started to evolve in Africa and elsewhere. The sustainability of the growing industry, the profitability of small- and medium-scale enterprises (SMEs) that are active in the industry and good-health of consumers can best be guaranteed through the adoption of proper quality and food safety procedures. Cassava processing enterprises involved in the productionof HQCF must therefore be commited to the quality and food safety of the HQCF. They must have the right technology, appropriate processing machhinery, standard testing instruments and the necessary technical expertise. This quality manual was therefore developed to guide small- to medium-scale cassava in the design and implematation of Hazard Analysis Critical Control Point (HACCP) system and Good manufacturing Practices (GMP) plans for HQCF production. It describes the HQCF production methods, and explanins in practical terms the concept of HACCP/QACCP quality system and procedure for aplication to HQCF production. The procedures described in this manual should help cassava processing enterprises to implement the HACCP/QACCP system from the point of root delivery through every processing operation to marketing of high quality cassava flour ensuring that the microbiological, physical and chemical standards of the product are met. It is expected that the use of this manual will facilitate the development of thé cassava processing sub-sector, assist in making HQCF meet the quality and safety limits of all categories of end users and make HQCF compete favorably with imported products. It will also aid regulatory agencies in different cassava-growing countries to set achievable quality objectives for HQCF.
