Rompre (2011)

Les amies de Variations John Holloway Rompre 1. Rompre. Nous voulons rompre. Nous voulons crer un monde nouveau. Maintenant. Rien de plus banal, rien de plus vident. Rien de plus simple. Rien de plus difficile. Rompre. Nous voulons rompre. Nous voulons briser le monde tel qu'il est. Un monde d'injustices, de guerres, de violences, de discriminations, de Gaza et de Guantnamo. Un monde de milliardaires avec un milliard de gens qui vivent et meurent de faim. Un monde dans lequel l'humanit s'annihile elle-mme, massacre les formes non humaines de vie et dtruit les conditions de sa propre existence. Un monde gouvern par l'argent, gouvern par le capital. Un monde de frustrations et de gaspillage des possibilits. Nous voulons crer un monde nouveau. Nous protestons ; bien sr, nous protestons. Nous protestons contre la guerre, contre l'utilisation croissante de la torture dans le monde ; nous protestons contre la transformation de toute forme de vie en marchandise vendre et acheter, nous protestons contre le traitement inhumain des immigrs, nous protestons contre la destruction du monde dans l'intrt des profits. Nous protestons et nous faisons davantage. Nous le faisons et nous devons le faire. Si nous protestons seulement, nous permettons aux puissants de mettre en avant leur ordre du jour. Si tout ce que nous faisons consiste s'opposer ce qu'ils essaient de faire, alors nous ne faisons simplement que nous mettre dans leurs pas. Rompre signifie que nous faisons davantage que cela,
K-swaps: cooperative negotiation for solving task-allocation problems (2009)

In this paper, we study distributed algorithms for cooperative agents that allow them to exchange their assigned tasks in order to reduce their team cost. We define a new type of contract, called K-swaps, that describes multiple task exchanges among multiple agents at a time, which generalizes the concept of single task exchanges. We design a distributed algorithm that constructs all possible K-swaps that reduce the team cost of a given task allocation and show that each agent typically only needs to communicate a small part of its local computation results to the other agents. We then demonstrate empirically that K-swaps can reduce the team costs of several existing task-allocation algorithms significantly even if K is small. 1
The CsdA cysteine desulphurase promotes Fe/S biogenesis by recruiting Suf components and participates to a new sulphur transfer pathway by recruiting CsdL (ex‐YgdL), a ubiquitin‐modifying‐like protein (2009)

Cysteine desulphurases are primary sources of sulphur that can eventually be used for Fe/S biogenesis or thiolation of various cofactors and tRNA. Escherichia coli contains three such enzymes, IscS, SufS and CsdA. The importance of IscS and SufS in Fe/S biogenesis is well established. The physiological role of CsdA in contrast remains uncertain. We provide here additional evidences for a functional redundancy between the three cysteine desulphurases in vivo. In particular, we show that a deficiency in isoprenoid biosynthesis is the unique cause of the lethality of the iscS sufS mutant. Moreover, we show that CsdA is engaged in two separate sulphur transfer pathways. In one pathway, CsdA interacts functionally with SufE-SufBCD proteins to assist Fe/S biogenesis. In another pathway, CsdA interacts with CsdE and a newly discovered protein, which we called CsdL, resembling E1-like proteins found in ubiquitin-like modification systems. We propose this new pathway to allow synthesis of an as yet to be discovered thiolated compound.
Genovo: De Novo Assembly for Metagenomes (2011)

Next-generation sequencing technologies produce a large number of noisy reads from the DNA in a sample. Metagenomics and population sequencing aim to recover the genomic sequences of the species in the sample, which could be of high diversity. Methods geared towards single sequence reconstruction are not sensitive enough when applied in this setting. We introduce a generative probabilistic model of read generation from environmental samples and present Genovo, a novel de novo sequence assembler that discovers likely sequence reconstructions under the model. A nonparametric prior accounts for the unknown number of genomes in the sample. Inference is performed by applying a series of hill-climbing steps iteratively until convergence. We compare the performance of Genovo to three other short read assembly programs in a series of synthetic experiments and across nine metagenomic datasets created using the 454 platform, the largest of which has 311k reads. Genovo's reconstructions cover more bases and recover more genes than the other methods, even for low-abundance sequences, and yield a higher assembly score.

Portable Haptic Interface with Active Functional Design (1999)

Haptic rendering is the process of computing and generating forces in response to user interactions with virtual objects. The interaction modality of haptic feedback gains more and more of importance for simulation tasks in virtual environments. However there are only very few portable haptic interfaces, with which the user can experience in a natural way the sensation of force feedback. The scope of this paper is to present a new portable haptic interface using shape memory alloy wires as actuators. Shape memory alloys (SMA), and especially the nickel-titanium compositions, offer a number of engineering properties available in no other material. The ability to respond with significant force and motion to small changes in ambient temperature and the capability to convert heat energy into mechanical work provide the designer with a new array of possibilities. Beside some application specific characterization of the actuator material with respect to energy consumption and dynamic behavior for loading, the mechanical layout of the interface is discussed in detail. To realize a light and compact design of the interface, a flexure hinge is considered as an essential part of interface.
Resection of Calcified Aortic Heart Leaflets In Vitro by Q-Switched 2 µm Microsecond Laser Radiation (2014)

The Q-switched Tm:YAG laser system showed promising results in cutting calcified aortic valves, by transmitting sufficient energy through a small flexible fiber. Catheter-based removal of aortic valve calcification may help to improve TAVI technology.
Interferometric measuring system for cone inspection on shop-floor level (2015)

Small and precise cones are one of the most important functional surfaces for valve seats of today's modern common rail injection systems for Diesel engines. We have investigated two concepts of interferometric systems for industrial examination of small-size conical geometries: white-light-interferometer with an endoscopic probe and a special formmeasuring- machine with an interferometric stylus. Endoscopic probes are critical for small and deep drillings, and the optical layout becomes very complex and expensive. To increase the universality of small size cone measuring systems, we followed the concept of a special scanning form measuring machine using a single-measuring-point interferometric stylus. We have performed first measurements and repeatability tests on the shop floor. Based on standard capability evaluation (Cgk and Cg) we have achieved the following measuring system capabilities: angle T&lt; 0.07°, roundness T&lt;0.3 μm, Pt Value &lt;0.3 μm.
Tri‐fold process integration leveraging high‐ and low‐temperature plasmas: From biomass to fertilizers with local energy and for local use (2021)

Abstract In the present study, a series of thermochemical equilibrium modeling was conducted to assess the thermodynamic potential of biomass conversion to ammonia using thermal and nonthermal plasma at small‐ and large‐scale production. The system was designed and evaluated for five different locations in Australia including the Northern Territory, South Australia, Western Australia, and New South Wales using local biomass feedstock. The equilibrium modeling showed that the pathway of biomass to biomethane using an anaerobic digestion reactor, biomethane to hydrogen using a thermal plasma reactor, followed by conversion of hydrogen to ammonia via a nonthermal plasma reactor is a plausible route, by which the exergy efficiency of the process can be as high as ~60%. It is identified that the thermal plasma reactor required two distinct zones at 3000°C &lt; T &lt; 4000°C and 1500°C &lt; T &lt; 2500°C. The first zone aims at converting electric energy into very high temperature thermal flow while the second one enables to split methane molecules into solid carbon and hydrogen. The new ammonia process is also assessed from the viewpoint of the current industrial transformation, being accelerated by the post‐COVID economy, which moves toward local, resilient, integrated and self‐sufficient production under the umbrella of an emerging fractal economy. With respect to local production, the developed process is designed for a quick response to farm use and on‐time production in view of the demands of modern ICT‐sensor based precision agriculture. The proposed process was found to be flexible (“resilient”) against production scale, geographical location, price and type of feedstock, and source of renewable energy. The system was found to be flexible against different feedstock such as spent grape marc, mustard seed, bagasse, piggery and poultry. The system can be self‐sustained up to ~80% at T = 3500°C; with the thermal plasma reactor‐zone 2 producing the electricity requirements for the nonthermal plasma via a steam turbine power block. Finally, the system it is investigated to which degree the system is adaptable to local production, self‐sufficient, and circulatory.
What Did I Ask You to Do, by When, and for Whom? (2017)

Request management occurs at an intersection of CSCW and personal information management (i.e., to-do management), with particular emphasis on social relationships and organizational accountability. We explore diverse work practices and representations for person-to-person requests in organizations, detailing the scatter of communications channels, difficulty of aggregation and prioritization, differences due to context, and the sometimes extraordinary effort and passion that knowledge workers expend on this part of their work, as well as the compassion with which they view their colleagues' efforts. We close with a proposal for the study of socially implicated objects in physical and/or virtual organizations, and implications for the design of services to support request management.
Studio sulla disidratazione e decomposizione di decavanadati mediante spettri IR (1974)

The stabilizing effect of water on the decavanadate ion has been studied by IR spectroscopy on a number of decavanadates at different dehydratation levels. The results suggest particular relations existing in decavanadate stabilization by protonation in aqueous solution and by hydratation in solids. &#13;\nThe polyanion needs at least 2 water molecules in order to be stabilized. When they are removed, it decomposes giving products Whose nature depends on the type of the cations used.
Releasing the A3 pulley and leaving flexor superficialis intact increases pinch force following the Zancolli lasso procedures to prevent claw deformity in the intrinsic palsied finger (2002)

Objective estimates of fingertip force magnitude following surgery to prevent digital metacarpophalangeal (MCP) hyperextension (clawing) in cases of paralysis of the hand's intrinsic muscles will assist clinicians in setting realistic expectations for post-operative pinch strength. We used a cadaveric/optimization approach to predict and confirm the maximal biomechanically possible fingertip force in the intrinsic palsied hand before and after two popular tendon transfer methods to the volar plate of the MCP joint. Both surgeries were also evaluated after release of the A3 pulley-a modification predicted by our published computer model of the forefinger to increase fingertip force magnitude. We predicted maximal static fingertip force by mounting eight fresh cadaveric hands on a frame, placing their forefinger in a functional posture (neutral abduction, 45 degrees of flexion at the MCP and proximal interphalangeal joints, and 10 degrees at the distal interphalangeal joint) and pinning the distal phalanx to a 3D dynamometer. We pulled on individual tendons with tensions up to 25% of maximal isometric force of their associated muscle and measured fingertip force and torque output. Using these measurements, we predicted the optimal combination of tendon tensions that maximized palmar force (analogous to pinch force, directed perpendicularly from the midpoint of the distal phalanx, and in the plane of finger flexion-extension) for four cases: (i) the non-paretic case (all muscles available), (ii) intrinsic palsied hand (no intrinsic muscles functioning), (iii) transfer of flexor superficialis tendon to the volar plate of the MCP (Zancolli lasso) in the intrinsic palsied hand, and (iv) leaving flexor superficialis intact and transferring a tendon of comparable strength to the volar plate of the MCP in the intrinsic palsied hand. Lastly, we applied these optimal combinations of tension to the cadaveric tendons and measured fingertip output. With the A3 pulley intact, the maximal palmar force in cases (ii)-(iv) averaged 48 +/- 23% SD (non-paretic = 100%; case (iv) (61 +/- 25%) > cases (ii) and (iii) (43 +/- 23% and 39 +/- 19%, respectively), p < 0.05). Releasing the A3 pulley significantly increased the average palmar force in cases (ii)-(iv) (73 +/- 42%, p < 0.05), with no significant differences among them. Thus, releasing the A3 pulley may improve palmar force magnitude when it is necessary to transfer the digit's own flexor superficialis tendon to the volar plate of the MCP to prevent clawing in the intrinsic palsied hand.
Development, characterization and toxicological evaluations of phospholipids complexes of curcumin for effective drug delivery in cancer chemotherapy (2014)

The purpose of this study was to prepare and characterize the complexes between curcumin (CU) phosphatidylcholine (PC) and hydrogenated soya phosphatidylcholine (HSPC) and to evaluate their anticancer activity. These CU-PC and CU-HSPC complexes (CU-PC-C and CU-HSPC-C) were evaluated for various physical parameters like Fourier transform infrared spectroscopy, melting point, solubility, scanning electron microscopy and the in vitro drug release study. These data confirmed the formation of phospholipids complexes. The in vitro hemolysis study showed that the complex was non-hemolytic. The anti-cancer potential of the complexes was demonstrated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay in MCF-7 cell line. This increase may be due to the amphiphilic nature of the complexes, which significantly enhances the water and lipid solubility of the CU. Unlike the free CU (which showed a total of only 90% drug release at the end of 8 h), complex showed around 40-60% release at the end of 8 h in dissolution studies. It showed that (when given in equimolar doses) complexes have significantly decreased the amount of CU available for absorption as compared with CU-free drug. Both CU-PC-C and CU-HSPC-C were found to be non-toxic at the dose equivalent to 2000 mg/kg of body weight of CU in the toxicity study. Acute and subacute toxicity studies confirmed the oral safety of the formulation. A series of genotoxicity studies was conducted, which revealed the non-genotoxicity potential of the developed complexes. Thus, it can be concluded that the phospholipid complexes of CU may be a promising candidate in cancer therapy.
Dynamic Mechanisms with Martingale Utilities (2017)

We study the dynamic mechanism design problem of a seller who repeatedly sells independent items to a buyer with private values. In this setting, the seller could potentially extract the entire buyer surplus by running efficient auctions and charging an upfront participation fee at the beginning of the horizon. In some markets, such as Internet advertising, participation fees are not practical since buyers expect to inspect items before purchasing them. This motivates us to study the design of dynamic mechanisms under successively more stringent requirements that capture the implicit business constraints of these markets. We first consider a periodic individual rationality constraint, which limits the mechanism to charge at most the buyer’s value in each period. While this prevents large upfront participation fees, the seller can still design mechanisms that spread a participation fee across multiple initial auctions. These mechanisms have the unappealing feature that they provide close-to-zero buyer utility in earlier auctions in exchange for higher utility in later auctions. To address this problem, we introduce a martingale utility constraint, which imposes the requirement that from the perspective of the buyer, the next item’s expected utility is equal to the present one’s. Our main result is providing a dynamic auction satisfying martingale utility and periodic individual rationality whose loss in profit with respect to first-best (full extraction of buyer surplus) is optimal up to polylogarithmic factors. The proposed mechanism is a dynamic two-tier auction with a hard floor and a soft floor that allocates the item whenever the buyer’s bid is above the hard floor and charges the minimum of the bid and the soft floor.

DIRECT SOLUTIONS OF THE MAXWELL EQUATIONS EXPLAIN OPPOSITION PHENOMENA OBSERVED FOR HIGH-ALBEDO SOLAR SYSTEM OBJECTS (2009)

Several spectacular backscattering effects observed for particulate planetary surfaces have been interpreted in terms of the effect of weak localization (WL) of electromagnetic waves. However, the interference concept of WL explicitly relies on the notion of phase of an electromagnetic wave and is strictly applicable only when particles forming the surface are widely separated. Therefore, one needs a definitive quantitative proof of the WL nature of specific optical effects observed for densely packed particulate media. We use numerically exact computer solutions of the Maxwell equations to simulate electromagnetic scattering by realistic models consisting of large numbers of randomly positioned, densely packed particles. By increasing the particle packing density from zero to ∼40%, we track the onset and evolution of the full suite of backscattering optical effects predicted by the low-density theory of WL, including the brightness and polarization opposition effects (BOE and POE). We find that all manifestations of WL, except the circular polarization ratio and POE, are remarkably immune to packing-density effects. Even POE can survive packing densities typical of planetary regolith surfaces. Our numerical data coupled with the results of unique observations at near-backscattering geometries demonstrate that the BOE and POE detected simultaneously for high-albedo solar system objects are caused by the effect of WL.
Lightly-Supervised Attribute Extraction (2007)

Web search engines can greatly benefit from knowledge about attributes of entities present in search queries. In this paper, we introduce lightly-supervised methods for extracting entity attributes from natural language text. Using these methods, we are able to extract large numbers of attributes of different entities at fairly high precision from a large natural language corpus. We compare our methods against a previously proposed pattern-based relation extractor, showing that the new meth-ods give considerable improvements over that baseline. We also demonstrate that query expansion using extracted attributes improves retrieval performance on un-derspecified information-seeking queries. 1 Attributes in Web Search Web search engines receive numerous queries requesting information, often focused on a specific entity, such as a person, place or organization. These queries are sometimes general requests, such as “bio of George Bush, ” or specific requests, such as “new york mayor. ” Accurately identifying the entity (new york) or related attributes (mayor) can improve search results in several ways [1].

Gas‐Grain Processes for the Formation of CH4and H2O: Reactions of H Atoms with C, O, and CO in the Solid Phase at 12 K (1998)

The reactions of H atoms with C, O, CO, and CH3CN in solid phase at 12 K were investigated by temperature-programmed mass spectrometry. In the reaction of H atoms with C atoms trapped in the CO matrix, H atoms migrate in the CO matrix and react with trapped C atoms selectively to form CH4. D2O was the major product from the reactions of D atoms with O atoms trapped in a N2O matrix. CH4 was found to be one of the final products from the reactions of H atoms with solid CO. The precursor for the formation of CH4 may be the CH2OH radical. No products were detected from the reaction of H atoms with CH3CN, suggesting that the nitrile group is not amenable to the hydrogenation reactions by H atoms at 12 K. When CH4 molecules are trapped in matrices such as CH3OH and H2O, the desorption of CH4 is greatly suppressed, i.e., from ~50 K for neat CH4 to ~100 K for CH4 in the CH3OH matrix and to ~150 K for CH4 in the H2O matrix.
