Opportunities and Challenges of Peer-to-Peer Internet Video Broadcast (2007)

There have been tremendous efforts and many technical innovations in supporting real-time video streaming in the past two decades, but cost-effective large-scale video broadcast has remained an elusive goal. Internet protocol (IP) multicast represented an earlier attempt to tackle this problem but failed largely due to concerns regarding scalability, deployment, and support for higher level functionality. Recently, peer-to-peer based broadcast has emerged as a promising technique, which has been shown to be cost effective and easy to deploy. This new paradigm brings a number of unique advantages such as scalability, resilience, and effectiveness in coping with dynamics and heterogeneity. While peer-to-peer applications such as file download and voice-over-IP have gained tremendous popularity, video broadcast is still in its early stages, and its full potential remains to be seen. This paper reviews the state-of-the-art of peer-to-peer Internet video broadcast technologies. We describe the basic taxonomy of peer-to-peer broadcast and summarize the major issues associated with the design of broadcast overlays. We closely examine two approaches - tree-based and data-driven - and discuss their fundamental tradeoff and potential for large-scale deployment. Lastly, we outline the key challenges and open problems and highlight possible avenues for future directions.
Feature Extraction and Classification from Boundary Representation (2003)

In the paper, an algorithm for explicit feature extraction and classification from boundary representation is presented. It operates in two phases: the topological and the geometrical. While the topological part is just an adaptation of an already known algorithm, the geometrical part represents an original and new solution. In this part, the algorithm manipulates with features filled by material and the empty ones. The algorithm classifies extracted features into eight classes. It successfully and efficiently handles voids, nested features and many cases of mutual feature intersections. The time complexity depends on input data, and never exceeds O(n^2).
Design, Fabrication, and Characterization of a High-Heating-Efficiency 3-D Microheater for Catalytic Gas Sensors (2012)

In this paper, a novel 3-D microheater has been developed in order to improve the performance of catalytic gas sensors. The 3-D microheater consists of a platinum heater embedded in a concave-shaped membrane which was formed in twice wet-chemical anisotropic etching with photoresist-spray-coating-based liftoff process. Based on the 3-D microheater, a catalytic gas sensor with a paired detector and compensator was developed by sol–gel process, introducing <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\gamma-\hbox{Al}_{2}\hbox{O}_{3}$</tex></formula> -supported 15-wt <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\%$</tex></formula> Pd as catalyst. Finite element method analysis results suggest that sensitivity of the catalytic gas sensor can be improved by loading more catalyst on the active area and concentrating more combustion heat inside the concave-shaped membrane. Test results indicate that a high heating efficiency has been achieved. Power per active area of the 3-D microheater is only half or less than that of current 2-D microheaters.

Statistical analysis of SSB phase noise test results (2003)

Statistical analysis results are reported of recent phase noise measurements on a production lot of 100 MHz to 111.25 MHz oscillators using third overtone SC-cut quartz crystals. The test results are from a lot of 262 units of 10 different frequencies. The results show the statistical variations of the close-in phase noise measurements of both the crystal and the completed oscillator. Phase noise is reviewed at 10 Hz to 40 MHz offset from the carrier and analyzed in detail at 100 Hz offset where crystal noise is critical to the noise performance of the oscillator. The final results show a significant improvement over previously reported production-run data. Measured noise readings as low as -136 dBc/Hz at 100 Hz with limited process capability greater than -140 dBc/Hz are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Scheduling to Minimize Average Completion Time: Off-Line and On-Line Approximation Algorithms (1997)

In this paper we introduce two general techniques for the design and analysis of approximation algorithms for 𝒩𝒫-hard scheduling problems in which the objective is to minimize the weighted sum of the job completion times. For a variety of scheduling models, these techniques yield the first algorithms that are guaranteed to find schedules that have objective function value within a constant factor of the optimum. In the first approach, we use an optimal solution to a linear programming relaxation in order to guide a simple list-scheduling rule. Consequently, we also obtain results about the strength of the relaxation. Our second approach yields on-line algorithms for these problems: in this setting, we are scheduling jobs that continually arrive to be processed and, for each time t, we must construct the schedule until time t without any knowledge of the jobs that will arrive afterwards. Our on-line technique yields constant performance guarantees for a variety of scheduling environments, and in some cases essentially matches the performance of our off-line LP-based algorithms.
Immunochemotherapy of Visceral Leishmaniasis: A Pilot Trial of Sequential Treatment with Recombinant Interferon-γ and Pentavalent Antimony (1993)

The clinical, parasitological, hematological, and serological evolution of visceral leishmaniasis in Brazilian patients was assessed during treatment with human recombinant interferon-gamma (rIFN-gamma; 0.1 mg/m2 i.m. days 1-14) followed by pentavalent antimony (Sbv; 10 mg/kg days 22-28). At day 30, 6 patients had improved, 2 had slightly improved, and 1 patient had deteriorated. IFN-gamma was well tolerated in the dose tested and may be very effective as an adjunct to conventional therapy with antimony.
Optimal peer selection for P2P downloading and streaming (2005)

In a P2P system, a client peer may select one or more server peers to download a specific file. In a P2P resource economy, the server peers charge the client for the downloading. A server peer's price would naturally depend on the specific object being downloaded, the duration of the download, and the rate at which the download is to occur. The optimal peer selection problem is to select, from the set of peers that have the desired object, the subset of peers and download rates that minimizes cost. In this paper we examine a number of natural peer selection problems for both P2P downloading and P2P streaming. For downloading, we obtain the optimal solution for minimizing the download delay subject to a budget constraint, as well as the corresponding Nash equilibrium. For the streaming problem, we obtain a solution that minimizes cost subject to continuous playback while allowing for one or more server peers to fail during the streaming process. The methodologies developed in this paper are applicable to a variety of P2P resource economy problems.
Low-noise sigma-delta capacitance-to-digital converter for Sub-pF capacitive sensors with integrated dielectric loss measurement (2008)

A sigma-delta capacitance-to-digital converter (CDC) with a resolution down to 19.3 aF at a bandwidth of 10 kHz, corresponding to a noise level of 0.2 aF/√Hz, is presented. An integrated dielectric loss measurement circuit by means of two parallel channels with different integration times offers a complex permittivity measurement in a single-chip solution. The achieved dielectric loss angle resolution is as low as 0.3° for a material density ratio of 0.55 %. A test chip with two converter blocks including two 2nd order and two 4th order modulators has been produced in the austriamicrosystems AG C35B3C0 0.35 μm DPTM CMOS process, operating at a single 3.3 V supply. Applications of this circuit include mass measurement and analysis of material compositions.

Design and comparison of command shaping methods for controlling residual vibration (2003)

The authors evaluate a signal generation technique for commanding high-performance machines to move without exciting residual vibration. This time-domain input-shaping technique works like a filter that is designed to eliminate decaying sinusoidal resonance responses. It is compared to a variety of filtering techniques and is shown to perform more effectively than any of them. In particular, frequency-domain filter design techniques are less effective for shaping vibration-reducing inputs to systems. The three-impulse shaping sequence offers significant performance advantages in that moves require less time and result in little or no residual vibration. In addition, the response is not sensitive to variations in the system parameters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Riociguat for chronic thromboembolic pulmonary hypertension and pulmonary arterial hypertension: a phase II study (2010)

We assessed the therapeutic potential of riociguat, a novel soluble guanylate cyclase stimulator, in adults with chronic thromboembolic pulmonary hypertension (CTEPH; n = 42) or pulmonary arterial hypertension (PAH; n = 33) in World Health Organization (WHO) functional class II/III. In this 12-week, multicentre, open-label, uncontrolled phase II study, patients received oral riociguat 1.0-2.5 mg t.i.d. titrated according to systemic systolic blood pressure (SBP). Primary end-points were safety and tolerability; pharmacodynamic changes were secondary end-points. Riociguat was generally well tolerated. Asymptomatic hypotension (SBP <90 mmHg) occurred in 11 patients, but blood pressure normalised without dose alteration in nine and after dose reduction in two. Median 6-min walking distance increased in patients with CTEPH (55.0 m from baseline (390 m); p<0.0001) and PAH (57.0 m from baseline (337 m); p<0.0001); patients in functional class II or III and bosentan pre-treated patients showed similar improvements. Pulmonary vascular resistance was significantly reduced by 215 dyn·s·cm(-5) from baseline (709 dyn·s·cm(-5); p<0.0001). 42 (56%) patients were considered to have experienced drug-related adverse events (AEs; 96% mild or moderate). Dyspepsia, headache and hypotension were the most frequent AEs. Study discontinuation because of AEs was 4%. These preliminary data show that riociguat has a favourable safety profile and improves exercise capacity, symptoms and pulmonary haemodynamics in CTEPH and PAH. Randomised controlled trials are underway.

On-Line Optimization of a Crude Distillation Unit with Constraints on Product Properties (2002)

The optimization of chemical processes has gained immense importance in the present day. This work is aimed at the on-line optimization of an industrial crude distillation unit (CDU). A nonlinear, steady-state CDU model has been developed in-house for this purpose. Model tuning parameters in the form of vaporization efficiencies were incorporated to minimize the discrepancy between the measured and simulated column parameters on-line. The crude feed composition, represented by the true boiling point (TBP) curve, is known to vary with time. A procedure was developed to back-calculate the TBP curve using on-line plant data. Finally, the objective function was formulated to simultaneously maximize the net achievable profit and set the product properties within a user-specified range. The entire scheme was tested using real plant data off-line, but the problem formulation is suitable for supervisory-level on-line optimization without further modifications. It is shown that substantial increases in profitability can be achieved using supervisory on-line optimization.

The Fuzzy Job-Shop Scheduling Based on Improved Genetic Algorithm (2007)

To improve the performance of the existing genetic algorithms for job shop scheduling problem and speed up searching for optimal scheduling solution, this paper analyzes the difficulty and characteristics of the operation-based coding and designs a new crossover, which is based on the job. As illustrative numerical examples, both 6times6 and 10 times 10 job-shop scheduling problems are considered. Through the comparative simulations with position-based crossover, the feasibility and effectiveness of the proposed crossover are demonstrated.
[Component removal from whole blood by means of gravity sedimentation]. (1994)

Our aim was to establish a new method for the separation of long-term storable blood components (red blood cells in additive solution and frozen plasma) from whole blood by a gravity sedimentation technique with hydroxyethyl starch. This investigation should offer a cheap and technically simple method of blood separation as an alternative to whole blood storage, valuable for autologous blood to extend the presurgical donation period. Although the separation of 8 whole blood units was successful, this method cannot be recommended for routine application. It is still too complicated, difficult to standardize and too time-consuming. Additionally, the cell contamination of the plasma is too high.
A new VLSI decoupling circuit for suppressing radiated emissions from multilayer printed circuit boards (2002)

This paper presents a new decoupling circuit for multi-power-terminal VLSIs to suppress strong radiated emissions caused by power plane resonance of multilayer printed circuit boards (PCBs). This circuit is based on a previous /spl pi/-network filter consisting of two capacitors and one power trace. The power trace, designed in agreement with transmission line theory, was used in place of the ferrite bead inductor of a conventional /spl pi/-network filter. The new circuit has been so designed that when a number of them are applied in combination to a multi-power-terminal VLSI, they can share capacitors, thus reducing the total number of capacitors required. Both calculated and measured high-frequency characteristics of power buses in PCBs show that in wide-band frequencies this new circuit isolates a VLSI, the source of switching noise, from power distribution buses, which would otherwise resonate that switching noise. Measurements of emissions from PCBs mounted with a 208-pin VLSI demonstrate that this circuit reduces emission levels more effectively than does conventional capacitor-only decoupling circuit.
Crown Ethers Enable Room-Temperature Synthesis of CsPbBr<sub>3</sub> Quantum Dots for Light-Emitting Diodes (2018)

The synthesis of all-inorganic cesium lead halide perovskite quantum dots (QDs) typically requires high temperatures, stringent conditions, large quantities of surface ligands, and judicious purification steps to overcome ligand-induced charge injection barriers in optoelectronic devices. Low-temperature syntheses generally require lower ligand concentrations but are severely limited by the low solubility of the Cs precursor. We describe an innovative and general approach employing crown ethers under ambient conditions to overcome these solubility limitations. The crown ethers facilitate complete dissolution of the CsBr precursor, rendering CsPbBr3 QD inks practical for device fabrication. The resultant light-emitting diodes (LEDs) displayed bright green emission, with a current efficiency and external quantum efficiency of 9.22 cd A–1 and 2.64%, respectively. This represents the first LED based on CsPbBr3 QDs prepared at room temperature. Lastly, the crown ethers form core–shell structures, opening new avenues to exploit their strong coordination strength.

How the Sequence of a Gene Specifies Structural Symmetry in Proteins (2015)

Internal symmetry is commonly observed in the majority of fundamental protein folds. Meanwhile, sufficient evidence suggests that nascent polypeptide chains of proteins have the potential to start the co-translational folding process and this process allows mRNA to contain additional information on protein structure. In this paper, we study the relationship between gene sequences and protein structures from the viewpoint of symmetry to explore how gene sequences code for structural symmetry in proteins. We found that, for a set of two-fold symmetric proteins from left-handed beta-helix fold, intragenic symmetry always exists in their corresponding gene sequences. Meanwhile, codon usage bias and local mRNA structure might be involved in modulating translation speed for the formation of structural symmetry: a major decrease of local codon usage bias in the middle of the codon sequence can be identified as a common feature; and major or consecutive decreases in local mRNA folding energy near the boundaries of the symmetric substructures can also be observed. The results suggest that gene duplication and fusion may be an evolutionarily conserved process for this protein fold. In addition, the usage of rare codons and the formation of higher order of secondary structure near the boundaries of symmetric substructures might have coevolved as conserved mechanisms to slow down translation elongation and to facilitate effective folding of symmetric substructures. These findings provide valuable insights into our understanding of the mechanisms of translation and its evolution, as well as the design of proteins via symmetric modules.
Introduction to API Standard 541, 4/sup th/ edition-form-wound squirrel cage induction motors-larger than 500 horsepower (2003)

API Standard 541 is the premier large induction motor specification, originally created for refining service, but now applied by many companies in a wide range of industries. The 4/sup th/ edition of this Standard has been released, and has many changes and improvements over previous editions. This paper reviews the significant changes relative to the 3/sup rd/ edition. In addition, major specification requirements that distinguish API 541 motors from motors that simply meet NEMA requirements are reviewed as well.
