Utilize Signal Traces from Others? A Crowdsourcing Perspective of Energy Saving in Cellular Data Communication (2014)

With the tremendous growth in wireless network deployment and increasing use of mobile devices, e.g., smartphones and tablets, improving energy efficiency in such devices, especially with communication driven workloads, is critical to providing a satisfactory user experience. Studies show that signal strength plays an important role on energy consumption of cellular data communications. While energy consumption can be minimized by accurately predicting signal strengths and reacting to it in real-time, the dynamic nature of wireless environments makes signal strengths highly unpredictable. In this paper, after analyzing in detail the signal strength variation and its impact on energy consumption, we propose to use crowdsourcing approach to optimize mobile devices' energy efficiency by utilizing signal strength traces reported/shared by other users/devices in cellular networks. Via a comprehensive measurement study, we observe that signal strength traces collected from different devices are pseudo-identical, and they even exhibit similar threshold-based behaviors in the relationship between signal strength and device power consumption. Based on our observations, we propose a predictive scheduling algorithm that: (i) selects the right set of signal strength traces based on its location, (ii) applies a filter to smooth out signal strengths and hide abrupt changes, (iii) digitizes the signal strength to “good” and “bad” areas, and (iv) schedules transmissions based on power-throughput characteristics to optimize the transmission energy efficiency. To demonstrate the efficacy of the proposed algorithms, we prototype the crowdsourcing-based predicative scheduling algorithm on Android-based smartphones. Our experiment results from real-life driving tests demonstrate that, by leveraging others' signal traces, mobile devices can save energy up to 35 percent compared to the conventional opportunistic scheduling, i.e., schedule transmissions only based on instantaneous channel conditions.
Potassium, calcium et magnésium dans la nutrition de l'ananas en Guinée. III. Influence sur la qualité du fruit (1961)

Faisant suite à l'exposé du plan et du déroulement de cette étude (Fruits, vol. 16, n¼ 2, p. 49-56), puis à celui des effets sur le rendement agronomique (Fruits, vol. 16, n¼ 3, p. 113-121), le présent article traite de l'influence du potassium, du calcium et du magnésium sur: - l'aspect extérieur des fruits (grosseur, forme, coloration de l'écorce) - les caractéristiques physiques et mécaniques de la chair (diamètre du coeur, texture, coloration interne, "remplissement" des yeux, rendement en jus) - les plus importants des caractères chimiques et organoleptiques (extrait sec, acidité, rapport extrait sec/acidité, parfum, saveur). On souligne le fait que les formules d'engrais devant conduire au rendement maximum coïncident avec l'obtention de la meilleure qualité sur les points essentiels de celle-ci. Deux développements dépassent le cadre des conclusions propres à l'essai étudié. L'un présente une mise au point sur le problème de la définition du poids moyen optimum. L'autre apporte des précisions nouvelles sur un point d'intérêt capital: les relations entre la saveur réelle des fruits et les déterminations chimiques habituelles (extrait sec et acidité)

Protein-Protein Interactions in the Tetraspanin Web (2005)

Tetraspanins are evolutionarily conserved membrane proteins that tend to associate laterally with one another and to cluster dynamically with numerous partner proteins in membrane microdomains. Consequently, members of this family are involved in the coordination of intracellular and intercellular processes, including signal transduction; cell proliferation, adhesion, and migration; cell fusion; and host-parasite interactions.
Elastomeric lag damper effects on flap-lag stability in forward flight (1994)

The effect of a new 'differential equation based' elastomeric lag damper model is examined on shaft-fixed flaplag stability in forward flight. The nonlinear elastomeric damper is modeled using a combination of linear and nonlinear springs and dashpots, and is characterized completely by a nonlinear constitutive differential equation. Since damper description is not based on the frequencyand amplitudedependent complex modulus components, it can conveniently be used in a variety of operating conditions, including multi-frequency excitations, varying rotor speeds, and different equilibrium conditions. For propulsive trim calculations, the nonlinear damper equation is solved simultaneously with the rotor and fuselage equilibrium relations, with the equilibrium damper response being accurately determined. Flaplag stability is calculated in the rotating frame about the propulsive trim condition using Floquet theory. For this, the perturbation damper equation is solved along with the linearized blade flap and lag equations, with damper-force appearing as a separate state. The elastomeric damper has a stabilizing influence on blade lag damping. Neglecting the equilibrium damper response overpredicts lag damping by 100%. Neglecting the cyclic components of equilibrium damper response (with collective included), overpredicts hingeless blade lag damping, but can accurately predict articulated blade lag damping up to advance ratios of 0.3. Lag damping decreases as disk load increases, more so for hingeless blades.
STAT3 mutations indicate the presence of subclinical T-cell clones in a subset of aplastic anemia and myelodysplastic syndrome patients (2013)

Large granular lymphocyte leukemia (LGL) is often associated with immune cytopenias and can cooccur in the context of aplastic anemia (AA) and myelodysplastic syndromes (MDS). We took advantage of the recent description of signal transducer and activator of transcription 3 (STAT3) mutations in LGL clonal expansions to test, using sensitive methods, for the presence of these mutations in a large cohort of 367 MDS and 140 AA cases. STAT3 clones can be found not only in known LGL concomitant cases, but in a small proportion of unsuspected ones (7% AA and 2.5% MDS). In STAT3-mutated AA patients, an interesting trend toward better responses of immunosuppressive therapy and an association with the presence of human leukocyte antigen-DR15 were found. MDSs harboring a STAT3 mutant clone showed a lower degree of bone marrow cellularity and a higher frequency of developing chromosome 7 abnormalities. STAT3-mutant LGL clones may facilitate a persistently dysregulated autoimmune activation, responsible for the primary induction of bone marrow failure in a subset of AA and MDS patients.

Interruption of Onchocerca volvulus Transmission in the Abu Hamed Focus, Sudan (2013)

Abu Hamed, Sudan, the northernmost location of onchocerciasis in the world, began community-directed treatment with ivermectin (CDTI) in 1998, with annual treatments enhanced to semiannual in 2007. We assessed the status of the parasite transmission in 2011 entomologically, parasitologically, and serologically. O-150 pool screening showed no parasite DNA in 17,537 black flies collected in 2011 (95% confidence interval upper limit [95% CI UL] = 0.023). Skin microfilariae, nodules, and signs of skin disease were absent in 536 individuals in seven local communities. Similarly, no evidence of Onchocerca volvulus Ov16 antibodies was found in 6,756 school children ≤ 10 years (95% CI UL = 0.03%). Because this assessment of the focus meets the 2001 World Health Organization (WHO) criteria for interrupted transmission, treatment was halted in 2012, and a post-treatment surveillance period was initiated in anticipation of declaration of disease elimination in this area. We provide the first evidence in East Africa that long-term CDTI alone can interrupt transmission of onchocerciasis.

Transient Ru-methyl formate intermediates generated with bifunctional transfer hydrogenation catalysts (2012)

Desorption electrospray ionization (DESI) coupled to high-resolution Orbitrap mass spectrometry (MS) was used to study the reactivity of a (β-amino alcohol)(arene)RuCl transfer hydrogenation catalytic precursor in methanol (CH(3)OH). By placing [(p-cymene)RuCl(2)](2) on a surface and spraying a solution of β-amino alcohol in methanol, two unique transient intermediates having lifetimes in the submillisecond to millisecond range were detected. These intermediates were identified as Ru (II) and Ru (IV) complexes incorporating methyl formate (HCOOCH(3)). The Ru (IV) intermediate is not observed when the DESI spray solution is sparged with Ar gas, indicating that O(2) dissolved in the solvent is necessary for oxidizing Ru (II) to Ru (IV). These proposed intermediates are supported by high-resolution and high mass accuracy measurements and by comparing experimental to calculated isotope profiles. Additionally, analyzing the bulk reaction mixture using gas chromatography-MS and nuclear magnetic resonance spectroscopy confirms the formation of HCOOCH(3). These results represent an example that species generated from the (β-amino alcohol)(arene)RuCl (II) catalytic precursor can selectively oxidize CH(3)OH to HCOOCH(3). This observation leads us to propose a pathway that can compete with the hydrogen transfer catalytic cycle. Although bifunctional hydrogen transfer with Ru catalysts has been well-studied, the ability of DESI to intercept intermediates formed in the first few milliseconds of a chemical reaction allowed identification of previously unrecognized intermediates and reaction pathways in this catalytic system.
Rare [(NHC)<sub>2</sub>Ni-OH]-Type Terminal Nickel Hydroxo and [(NHC)<sub>2</sub>Ni]-Type Complexes of<i>N</i>/<i>O</i>-Functionalized N-Heterocyclic Carbenes as Precatalysts for Highly Desirable Base-Free Michael Reactions in Air at Ambient Temperature (2009)

Highly convenient base-free Michael reaction of β-dicarbonyl, β-keto ester, and α-cyano ester compounds with activated ethylene compounds in air at ambient temperature catalyzed by a series of new nickel complexes, 1b−4b, of N/O-functionalized N-heterocyclic carbenes (NHC) are reported. Quite interestingly, of these nickel complexes, 1b and 2b were found to be of the [(NHC)2Ni-OH] type bearing a terminal [Ni-OH] moiety and are among the few known structurally characterized examples of monomeric terminal [Ni-OH] complexes. Compounds 3b and 4b, on the other hand, were found to be of the commonly encountered [(NHC)2Ni]-type complexes. More significantly, both the [(NHC)2Ni-OH]-type complexes 1b and 2b and the [(NHC)2Ni]-type complexes 3b and 4b were synthesized using same synthetic methodology by sheer modulation of the N-substituents on the N-heterocyclic carbene ring by the reaction of the imidazolium chloride salts with NiCl2·6H2O in the presence of K2CO3 as a base.
Pacifist's guide to optical computers (1991)

Optical algebraic processors can perform complex calculations in parallel and at high speeds. However, they commonly suffer from a low analog accuracy which hinders their widespread application. Error detection and correction codes provide one technique for improving the accuracy of optical algebraic processors. The use of these codes would allow some of the errors that may occur during a computation to be detected and possibly corrected. This paper describes the results of various computer simulations of optical matrix-vector multipliers employing error-correction codes. It discusses the application of convolutional codes to optical matrix-vector multipliers along with several block codes. Both binary and nonbinary codes are not employing error-correction codes. Also, the type of noise, whether signal-independent or signal-dependent, has a significant effect on the performance of a matrix-vector multiplier employing an error code. The encoding and decoding operations required for the error codes can be performed optically.
Optical neural network with autonulling bridge cells using a nearest-neighbor interconnection scheme (2003)

A cellular neural network (CNN) using autonulling bridge networks as the unit cells is discussed. This system uses phototransistors as optically controlled transducers in the unknown branch of the bridge. When incorporated either as an input to a CNN or as an integral part of a CNN, the phototransistor-bridge cell (PBC) offers a means to detect small signal changes on large background levels in real-time. It also enables the reduction of noise using the interconnection techniques established for CNNs. The inherent properties of the bridge network also contribute to noise reduction. The stability of the stand-alone PBC is discussed, and PSPICE simulations are conducted for a single PBC and a 4*4 array of PBCs with nearest-neighbor interconnection.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Digital analysis of the electroencephalogram, the blood pressure wave, and the electrocardiogram (1972)

The electroencephalogram (EEG), the blood pressure wave, and the electrocardiogram (ECG), produce patterns that the eye of the physician has empirically correlated with important aspects of health. Digital computer techniques for the recognition of these patterns are made particularly difficult by the realities of pattern context sensitivity, frequent signal artifact, real-time operation, finite storage limitations, and reasonable cost. Evaluations of these techniques are handicapped by the absence of absolute standards, the wide signal variability associated with pathologic states, and the sheer mechanics of comparison with human analysis. Computer analysis of the EEG has been directed toward monitoring sleep and certain pathologic states, leaving the more difficult problem of diagnosis to the trained neurologist. Automatic pattern recognition of the blood pressure wave has been implemented with straightforward techniques for diagnostic use in the cardiac catheterization laboratory and for monitoring in the intensive care unit. Computer analysis of the ECG has been directed toward morphological and rhythm diagnosis, having great potential utility in clinical heart stations, and toward rhythm monitoring, a most practical application arising in coronary intensive care units. Promising systems are emerging, but years of evaluation and adjustment will be necessary to meet the need for both accuracy and economy.
Significance of formants from difference spectrum for speaker identification (2006)

In this paper, we describe a prototype speaker identification system using auto-associative neural network (AANN) and formant features. Our experiments demonstrate that formants extracted from difference spectrum perform significantly better than formants extracted from normal spectrum for the task of speaker identification. We also demonstrate that formants from difference spectrum provide comparable speaker identification performance with that of features such as weighted linear predictive Cepstral coefficients and Mel-Frequency Cepstral coefficients. Finally, we combine the results of formant based system and linear predictive Cepstral coefficients based system to achieve 100% identification performance.
Vibration Absorption Control of Industrial Robots by Acceleration Feedback (1983)

This paper describes an electrical control method of absorbing arm vibrations of industrial robots. Arm vibration problems are divided into two categories: resonance vibration phenomenon depending on actuator velocity and transient oscillations caused by acceleration change of actuators. Because resonance frequency of an industrial robot changes more than double due to the arm posture, mechanical vibration absorbing methods may not be easily utilized. The method applied in this paper is to compose dampers as electric manners by utilizing arm acceleration feedback to actuators of an industrial robot. Acceleration sensors are attached on three axes which construct a robot arm. Acceleration signals are fed back to the corresponding actuators passed through phase compensation circuits. By experiments applied to an industrial robot, this method has been proved to be effective in eliminating both resonance and transient vibrations. According to this control, a smart motion industrial robot which does not have resonance characteristics and operates speedily and smoothly has been realized.
Synchronization for dynamic blending of motions (2004)

In this paper we present a new real-time synchronization algorithm. In dynamic environments, motions need to be continuously adapted to obtain realistic animations. We propose an advanced time warping algorithm to synchronize such motions. This algorithm uses the sequence of support phases of the motions. It also takes into account the priority associated to each motion. It is based on an algebraic relation to detect incompatible motions and to select elements of the sequence to be enlarged. The resulting time warping function can be non-derivable so it is corrected by using a cardinal spline interpolation. In this paper, we demonstrate that our algorithm always finds at least one solution. This synchronization module is part of a complete animation engine called MKM already used in production.
