This paper aims to ask the question whether, in Husserl’s perspective, all consciousness is intentional and to explore the alternatives. Thus, we have proceeded to a thorough analysis of Husserl’s texts concerning temporality and the rather bizarre type of intentionality that it implies. The examining of this intentionality that Husserl calls “longitudinal intentionality” has brought us to the conclusion that its intentional character incomprehensible unless we change our very concept of intentionality which cannot be anymore that of an object-relation, as it were defined in the Logical Investigations. It is, therefore, the very limit of intentionality that is revealed by our questioning the time-consciousness in Husserl. [less ▲]

D’optique philosophique, cet ouvrage est une mise en perspective de deux auteurs que tout semble séparer : Edmond Husserl, père d’une phénoménologie transcendantale de la conscience, et André Leroi-Gourhan, ethnologue et préhistorien. Une fois opérées les mises au point méthodologiques de rigueur, un dialogue s’établit entre Husserl et Leroi-Gourhan autour des « objets de la préhistoire » : ossements, cailloux taillés, traces d’ocre, de feu, d’habitats, objets gravés ou peints. Procédant par « zigzags », de la phénoménologie à la préhistoire et inversement, Bénédicte de Villers entend se tenir au plus près de la matérialité de ces objets préhistoriques et les décrire. En même temps, ceux-ci s’avèrent les seuls indices de subjectivités humaines d’autrefois et de leurs cultures. L’ambivalence des objets de la préhistoire constitue donc aussi toute leur richesse. L’« ontologie préhistorique » qui se construit dans ces pages, à la croisée des perspectives phénoménologiques et préhistoriques, vise ainsi à poser d’une façon originale la question de la « différence anthropologique » et des origines de l’homme.

Huygens is ESA’s main contribution to the joint NASA/ESA/ASI Cassini/Huygens mission to Saturn and its largest moon Titan. The Probe, delivered to the interface altitude of 1270 km above the surface by NASA/JPL Cassini orbiter, entered the dense atmosphere of Titan on 14 January 2005 and landed on the surface after a descent under parachute of slightly less than 2.5 hours. Huygens continued to function after landing for more than 3 hours. Data was transmitted and successfully recovered by Cassini continuously during the parachute descent and for 72 minutes on the surface. Although the Huygens attitude reconstruction based on the flight engineering parameters was not foreseen during the development phase (no gyros were included), a rough descent under parachute and indications of an anomaly in the probe spin direction make the engineering dataset valuable in the frame of the ADRS (Huygens Attitude Determination and Reconstruction Subgroup) as a complement to the scientific measurements. In addition, several scientific teams have a strong interest in understanding the orientation of the probe for interpreting their data, as DISR (Descent Imager and Spectral Radiometer) and HASI-PWA (Huygens Atmospheric Structure Instrument-Permeability, Wave and Altimetry). In this paper we describe the engineering parameters used for the Probe attitude reconstruction (Clausen et al., 2002), namely the radio link AGC (Automatic Gain Control), RASU and CASU (Radial and Central Accelerometer Sensor Units) and RAU (Radar Altimeter Unit). We explain the methodology applied to indirectly infer the attitude information from the measurements of these sensors. We also discuss and present the reconstructed information related to attitude: spin rate and azimuthal position (during the atmospheric descent), and landing orientation. Tip and tilt implications are still being worked at the time of writing. Preliminary data on their behavior is presented. [less ▲]

This paper presents three HVDC modulation strategies to improve transient stability in an interconnected power system. AC variables such as rotor speeds, voltage phasors, and tieline power flows are used as input to the controller that modifies the power flow settings through the HVDC-links. The proposed techniques are tested on the IEEE 24-Bus reliability test system and critical clearing times obtained for several contingencies are analyzed. The paper shows that HVDC modulation can lead to substantial improvement in transient stability. [less ▲]

BACKGROUND: The effectiveness of intra-articular hyaluronic acid (IAHA) injection for knee osteoarthritis (KOA) is debated. OBJECTIVES: To evaluate the effect of IAHA for patients with KOA by analysing data from trials of IAHA versus placebo with low risk of bias, to provide the highest level of evidence. METHODS: A systematic review and meta-analysis was conducted. Randomised controlled trials (RCTs) with a low risk of bias (adequate randomisation and concealment and double-blind design) that investigated IAHA versus placebo (saline solution) injection were eligible. The primary efficacy measure was pain intensity and secondary outcome function at 3 months. The treatment effect was summarised with the standardised mean difference (SMD) calculated from differences in means of pain and function measures between treatment and control groups at 3 months. Trials were pooled by a random-effects model with DerSimonian and Laird weights. Statistical heterogeneity was explored by a visual exploration of forest plots and the I(2) statistic. RESULTS: A total of eight RCTs (2 199 randomised patients) met our inclusion criteria. IAHA significantly reduced the pain intensity (SMD=-0.21, 95% CI (95% CI) -0.32 to -0.10) and improved function (SMD=-0.12, 95% CI -0.22 to -0.02). Trials showed no heterogeneity. CONCLUSIONS: This meta-analysis of high-quality trials of IAHA versus placebo shows that IAHA provides a moderate but real benefit for patients with KOA. [less ▲]

Hyaluronan (HA) is a glycosaminoglycan synthesized directly into the extracellular matrix by three hyaluronan synthases (HAS1, HAS2, and HAS3). HA is abundantly synthesized by keratinocytes but its epidermal functions remain unclear. We used culture models to grow human keratinocytes as autocrine monolayers or as reconstructed human epidermis (RHE) to assess HA synthesis and HAS expression levels during the course of keratinocyte differentiation. In both the models, epidermal differentiation downregulates HAS3 mRNA expression while increasing HAS1 without significant changes in hyaluronidase expression. HA production correlates with HAS1 mRNA expression level during normal differentiation. To investigate the regulation of HAS gene expression during inflammatory conditions linked to perturbed differentiation, lesional and non-lesional skin biopsies of atopic dermatitis (AD) patients were analyzed. HAS3 mRNA expression level increases in AD lesions compared with healthy and non-lesional skin. Simultaneously, HAS1 expression decreases. Heparin-binding EGF-like growth factor (HB-EGF) is upregulated in AD epidermis. An AD-like HAS expression pattern is observed in RHE incubated with HB-EGF. These results indicate that HAS1 is the main enzyme responsible for HA production by normal keratinocytes and thus, must be considered as an actor of normal keratinocyte differentiation. In contrast, HAS3 can be induced by HB-EGF and seems mainly involved in AD epidermis [less ▲]

Introduction: Recently, the viscoelastic properties of hyaluronic acid on liquid connective tissue have been proposed for the treatment of tendinopathies. Some fundamental studies show encouraging results on hyaluronic acid’s ability to promote tendon gliding and reduce adhesion as well as to improve tendon architectural organisation. Some observations also support its use in a clinical setting to improve pain and function. This literature review analyses studies relating to the use of hyaluronic acid in the treatment of tendinopathies. Methods: This review was constructed using the Medline database via Pubmed, Scopus and Google Scholar. The keywords hyaluronic acid, tendon and tendinopathy were used for the research. Results: In total, 27 articles (in English and French) on the application of hyaluronic acid to tendons were selected for their relevance and scientific quality, including eight for the 'in vitro' part, three for the 'in vivo' animal part and six for the human section. Conclusions: Preclinical studies demonstrate encouraging results: HA permits tendon gliding, reduces adhesions, creates better tendon architectural organisation and limits inflammation. These laboratory observations appear to be supported by limited but encouraging short-term clinical results on pain and function. However, controlled randomised studies are still needed. [less ▲]

This paper addresses the problem of computing an exact and effective representation of the set of reachable configurations of a linear hybrid automaton. Our solution is based on accelerating the state-space exploration by computing symbolically the repeated effect of control cycles. The computed sets of configurations are represented by Real Vector Automata (RVA), the expressive power of which is beyond that of the first-order additive theory of reals and integers. This approach makes it possible to compute in finite time sets of configurations that cannot be expressed as finite unions of convex sets. The main technical contributions of the paper consist in a powerful sufficient criterion for checking whether a hybrid transformation (i.e., with both discrete and continuous features) can be accelerated, as well as an algorithm for applying such an accelerated transformation on RVA. Our results have been implemented and successfully applied to several case studies, including the well-known leaking gas burner, and a simple communication protocol with timers. [less ▲]
