Influence des conditions climatiques sur un capteur d'allongement souple, compatible textile (2009)

Dans le cadre du développement de vêtements intelligents et de systèmes interactifs, il y a un besoin important d'évaluer les déformations des structures souples. Les capteurs d'allongement classiques (métalliques ou fibres optiques) étant mal adaptés aux textiles dans la mesure où ils ne sont ni très souples, ni très élastiques, nous avons développé une nouvelle génération de capteurs piezorésistifs basée sur un composite polymère conducteur. Ce composite, réalisé à partir d'un mélange en voie solvant de nano-particules de noir de carbone et d'une matrice polymère composeé d'un élastomère thermoplastique, est déposé directement sur un tissu. Le capteur obtenu est ainsi capable, via le changement de résistance électrique, de rendre compte de l'allongement de la structure support. La première partie de l'étude est dédiée à la réalisation des capteurs et à leur caractérisation électromécanique de base. L'étude de l'effet des conditions climatiques extérieures telles que la température (T) et l'humidité relative (HR) sur le capteur textile est ensuite plus particulièrement décrite. Les résultats obtenus à partir des cycles de simulation en T/HR dans une enceinte climatique sont exposés, analysés et discutés. Le but final de ce travail est de modéliser mathématiquement le comportement du capteur dans des conditions atmosphériques réelles et variables.
Relapse and Acquired Rifampin Resistance in HIV-Infected Patients with Tuberculosis Treated with Rifampin- or Rifabutin-Based Regimens in New York City, 1997-2000 (2005)

The risk for ARR among HIV-infected persons with TB did not depend on the rifamycin used but, rather, on the rifampin dosing schedule in the intensive phase of treatment.
Dependence of the He-Scattering Potential at Surfaces on the Surface-Electron-Density Profile (1980)

It is shown that the repulsive part of the He-surface interaction is given by an almost linear, surface-independent function of the surface electron density at the He site. This gives a very simple connection between the measured low-energy He-beam scattering potentials and the substrate electron densities. The scheme is applied to an analysis of the He-scattering potential outside Al.
The biology of Canadian weeds. 142. Camelina alyssum (Mill.) Thell.; C. microcarpa Andrz. ex DC.; C. sativa (L.) Crantz. (2009)

This paper summarizes biological information on three cruciferous weed species: Camelina alyssum, C. microcarpa and C. sativa. Camelina sativa, which had been gathered or cultivated as an oil seed for many centuries in Europe, was the first to reach North America as a weed, towards the mid-19th century, gradually spreading across the prairies, mainly in crops, to British Columbia and the Northwest Territory. The most common of the three species in North America, C. microcarpa, arrived in the late 19th century, and subsequently appeared at numerous crop and uncultivated sites across the country, probably in cargo as the railways expanded. Camelina alyssum appeared in the early 20th century at restricted sites on the prairies, mostly in Saskatchewan. All three species have diminished in importance as crop weeds in western Canada over the past few decades. This reduction could be related to increased weed control by herbicides. Herbicide-resistant biotypes have recently been reported in C. microcarpa. Camelina sativa has attracted renewed interest as an oil crop, because of an adaptation to various climatic conditions, low nutrient requirements and resistance to disease and pests. In Europe, where it is now widely grown, it has shown considerable potential in the food, animal feed, nutraceutical, paint, dye, cosmetic and biofuel industries. In North America, it is being grown on a trial basis mainly for its potential as a biofuel in Alberta, Saskatchewan, the Maritime Provinces, and the northern United States of America.Key words: Flat-seeded false flax, small-seeded false flax, large-seeded false flax, caméline alysson, caméline à petits fruits, caméline cultivée, weed biology
A discrete choice experiment to assess patients’ preferences for HIV treatment in the urban population in Colombia (2020)

<b>Aim:</b> This study aimed to assess patients' preferences for HIV treatment in an urban Colombian population.<b>Methods:</b> A Discrete Choice Experiment (DCE) was conducted. Urban Colombian HIV patients were asked to repetitively choose between two hypothetical treatments that differ in regard to five attributes 'effect on life expectancy', 'effect on physical activity', 'risk of moderate side effects, 'accessibility to clinic' and 'economic cost to access controls'. Twelve choice sets were made using an efficient design. A Mixed Logit Panel Model was used for the analysis and subgroup analyses were performed according to age, gender, education level and sexual preference.<b>Results:</b> A total of 224 HIV patients were included. All attributes were significant, indicating that there were differences between at least two levels of each attribute. Patients preferred to be able to perform all physical activity without difficulty, to have large positive effects on life expectancy, to travel less than 2 h, to have lower risk of side-effects and to have subsidized travel costs. The attributes 'effect on physical activity' and 'effects on life expectancy' were deemed the most important. Sub-analyses showed that higher educated patients placed more importance on the large positive effects of HIV treatment, and a more negative preference for subsidized travel cost (5% level).<b>Limitations:</b> A potential limitation is selection bias as it is difficult to make a systematic urban/rural division of respondents. Additional, questionnaires were partly administered in the waiting rooms, which potentially led to some noise in the data.<b>Conclusions:</b> Findings suggests that short-term efficacy (i.e. effect on physical activity) and long-term efficacy (i.e. effect on life expectancy) are the most important treatment characteristics for HIV urban patients in Colombia. Preference data could provide relevant information for clinical and policy decision-making to optimize HIV care.
Unprivileged Black-Box Detection of User-Space Keyloggers (2012)

Software keyloggers are a fast growing class of invasive software often used to harvest confidential information. One of the main reasons for this rapid growth is the possibility for unprivileged programs running in user space to eavesdrop and record all the keystrokes typed by the users of a system. The ability to run in unprivileged mode facilitates their implementation and distribution, but, at the same time, allows one to understand and model their behavior in detail. Leveraging this characteristic, we propose a new detection technique that simulates carefully crafted keystroke sequences in input and observes the behavior of the keylogger in output to unambiguously identify it among all the running processes. We have prototyped our technique as an unprivileged application, hence matching the same ease of deployment of a keylogger executing in unprivileged mode. We have successfully evaluated the underlying technique against the most common free keyloggers. This confirms the viability of our approach in practical scenarios. We have also devised potential evasion techniques that may be adopted to circumvent our approach and proposed a heuristic to strengthen the effectiveness of our solution against more elaborated attacks. Extensive experimental results confirm that our technique is robust to both false positives and false negatives in realistic settings.
Viral factors in influenza pandemic risk assessment (2016)

The threat of an influenza A virus pandemic stems from continual virus spillovers from reservoir species, a tiny fraction of which spark sustained transmission in humans. To date, no pandemic emergence of a new influenza strain has been preceded by detection of a closely related precursor in an animal or human. Nonetheless, influenza surveillance efforts are expanding, prompting a need for tools to assess the pandemic risk posed by a detected virus. The goal would be to use genetic sequence and/or biological assays of viral traits to identify those non-human influenza viruses with the greatest risk of evolving into pandemic threats, and/or to understand drivers of such evolution, to prioritize pandemic prevention or response measures. We describe such efforts, identify progress and ongoing challenges, and discuss three specific traits of influenza viruses (hemagglutinin receptor binding specificity, hemagglutinin pH of activation, and polymerase complex efficiency) that contribute to pandemic risk.
Late-onset familial Mediterranean fever in Japan (2019)

<b>Objectives:</b> Most patients with familial Mediterranean fever (FMF) have their first attack at age < 20 years. Information about late-onset (age ≥40 years) FMF is limited. We aimed to evaluate the demographic, clinical, and genetic characteristics of late-onset FMF patients in the Japanese population.<b>Methods:</b> We retrospectively analyzed 292 patients with FMF. Patients were divided into three groups according to age of disease onset: Group I, ≤19 years; Group II, 20-39 years; and Group III, ≥40 years.<b>Results:</b> Of 292 patients, 44 (15.1%) experienced their first attack at age ≥40 years. While high fever (97.7%) and arthritis (45.5%) were common symptoms in Group III patients, peritonitis (40.9%) and pleuritis (25.0%) were significantly lower than in other groups. The frequency of patients carrying p.M694I (18.2%), which is the most representative mutation in Japan, was significantly lower in Group III than in Group I. The response to colchicine therapy was good (95.1%) and similar in all groups.<b>Conclusions:</b> In Japan, more patients than expected had late-onset FMF. They had a milder form of disease, with less frequent peritonitis and pleuritis. The response to colchicine treatment was good. Clinicians should consider FMF for patients with unexplained recurrent febrile episodes, regardless of age.
Spektralanalysen des okulären Mikrotremors bei Hirnstammfunktionsstörungen (1987)

In 61 healthy and 79 patients the small involuntary movements were recorded using a piezoelecric strain gauge transducer mounted on a modified optical frame. The recording was followed by a spectralanalytic process with special programs. We used a detailed neurological examination for estimating the clinical condition of the patients. The spectral analysis of the ocular microtremor supplies results which correspond to the clinical condition in each case of the patients with increased central herniation. A irreversible loss of cerebral function (brain death) can also be documented. Patients with special clinical syndromes show tremograms which answer the probably extent of damage of (meso-)pontine parts. We investigated and discussed effects of the influence of central-nervous drugs, age-dependent relations, the significance of cardiovascular pulsations and questions and questions of the comparability of findings between both bulbi. The ocular microtremor shows burst-like components with a frequency peak between 60 and 90 oscillations per second. At present must be assessed that it could be a potential monitor of the function of the reticular (meso-)pontine formation.
Drift-free dynamic height sensor using MEMS IMU aided by MEMS pressure sensor (2008)

We demonstrate a low-cost, low-power, and small form factor solution to drift-free high-resolution vertical positioning by fusing MEMS accelerometers with MEMS barometric altimeter. In this system, the highly responsive but drift-prone aspect of the MEMS accelerometers is stabilized by barometric altimeter and high-fidelity height tracking is achieved. Typical vertical human movements such as walking up or down a staircase can be tracked in real-time with this system. The height tracking performance is benchmarked against a reference system using a tactical-grade IMU and an error analysis is performed.
Search for an excess in the production of four-jet events from e+e− collisions at =130–184 GeV (1998)

Events with four distinct jets from e+e− collisions, collected by the OPAL detector at centre-of-mass energies between 130 and 184 GeV, are analysed for a peak in the sum of dijet masses. This search is motivated by the ALEPH Collaboration's observation of a clear excess of events with dijet mass sums close to 105 GeV in data taken at centre-of-mass energies of 130 and 136 GeV in 1995. We have observed no significant excess of four-jet events compared to the Standard Model expectation for any dijet mass sum at any energy. Our observation is inconsistent with the excess observed by ALEPH in 1995. Upper limits are determined on the production cross-section as a function of the dijet mass sum.

Preparation of Novel Conductive Polymer Ligand-Coated Carbon Particles by Electropolymerization of Pyridylthiophene and Application as Metal Complex Catalysts for Oxygen Reduction (2006)

電解重合性を有する新しい配位性モノマーとして, 2-(3-チエニル) ピリジンを用いた流動層電解重合により, 配位子としてピリジル基を有する導電性高分子膜で被覆された炭素粒子を調製した. これを有機溶媒中に分散させ, 酢酸コバルトを用いた錯形成を行うことにより, 炭素粒子の表面にコバルト錯体を分散度高く修飾できることを見出した. 得られた修飾炭素粒子をNafion溶液に分散させ, 基板電極上にキャストすることにより擬似MEAを作製し, 溶存酸素の電解還元反応について検討した. 触媒担体として比表面積の大きいカーボンブラックを択び, 補助的な配位子としてピロールを用いた場合に, 貴な電位 (Ep=0.37V vs. SCE) および比較的高い反応選択度 (反応電子数n =3.1) で酸素の四電子還元が進行することが明らかになった. この活性は, コバルトポリピロール錯体修飾炭素粒子よりも高く, 塩基性度の高いピリジル基が活性点であるコバルトイオンの集積に寄与していることが示された. さらに, 得られた触媒を不活性ガス雰囲気下で熱処理することにより活性が著しく向上することが分かり, 燃料電池の新しいカソード触媒としての可能性が明らかになった.
Modeling Reverse Electro-Enhanced Dialysis for Integration with Lactic Acid Fermentation (2009)

Presently, economical and sustainability issues are the driving competitive forces behind improving process design and operation. Particularly, improvements in the sustainable production of commodity chemicals, such lactic acid, by fermentation are desirable when they are used as feedstock for production of polymers, e. g. polylactic acid (PLA). PLA can substitute hydrocarbon based polymers in several applications. It is well know that lactic acid production by fermentation is impaired by product inhibition at high lactate concentration in the cultivation broth. A continuous removal of lactate from the fermentation broth will diminish the inhibitory effect, and therefore increase productivity and product yield. Integrating separation and fermentation will also enable operation at higher cell densities, thereby providing additional enhanced productivity potential. Integration also moves the degrees of freedom for control, therefore a model based study of the design, control and optimization is desirable.
3D QSAR Methods:  Phase and Catalyst Compared (2007)

The programs Phase and Catalyst HypoGen are compared for their performance in determining three-dimensional quantitative structure-activity relationships. Eight sets of compounds with measured activity were collected from the public literature and partitioned into suitable training and test sets by an automated procedure. A range of models is built with each program, and suggested parameter variations are investigated. The models are assessed by their ability to predict the activity of compounds in the test set, and it is demonstrated that the performance of Phase is better than or equal to that of Catalyst HypoGen, with the data sets and parameters used here. Additionally, compounds in two of the data sets are overlaid on crystallographic structures of similar ligands in complex with the target receptor, in order to guide pharmacophore generation by the two programs, but the resulting models do not perform better.

Sensitivity and specificity of a new scoring system for diabetic macular oedema detection using a confocal laser imaging system (2001)

These data suggest that SCORE is potentially useful for detecting diabetic macular oedema in hospital diabetic patients.
High biological variation of serum hyaluronic acid and Hepascore, a biochemical marker model for the prediction of liver fibrosis (2012)

When using non-fasting serum samples, hyaluronic acid and to a lesser extent, the Hepascore model display large within-individual variations in both health and chronic liver disease. This information is critical for interpreting the significance of both single measurements and changes in serial measurements.
Proteomic tools to decipher microbial community structure and functioning (2014)

Recent advances in microbial ecology allow studying microorganisms in their environment, without laboratory cultivation, in order to get access to the large uncultivable microbial community. With this aim, environmental proteomics has emerged as an appropriate complementary approach to metagenomics providing information on key players that carry out main metabolic functions and addressing the adaptation capacities of living organisms in situ. In this review, a wide range of proteomic approaches applied to investigate the structure and functioning of microbial communities as well as recent examples of such studies are presented.
Intraventricular neuroepithelial tumors: surgical outcome, technical considerations and review of literature (2020)

Our surgical findings emphasize satisfactory complete resection throughout all entities. Surgical treatment can remain feasible, if institutional experience is given. Satisfying long-term survival and cure is possible by complete removal. Gross total resection should always be performed under function-remaining aspects due to mostly benign or slow growing nature of IVTs. Further data is needed to evaluate standard of care and alternative therapy options in rare cases of tumor recurrence or in case of patient collective not suitable for operative resection.
SENSOR VALIDATION IN DAMAGE LOCATING VECTOR METHOD FOR STRUCTURAL HEALTH MONITORING (2011)

The reliability of a structural health-monitoring system is very dependent on the quality of signals that are acquired and fed into the damage detection algorithm. Developed herein is an algorithm for sensor validation in the context of the damage locating vector (DLV) method for detecting damage in structures. Given the signals from ns sensors, ns combinatorial sets of signals from (ns - 1) sensors are formed. For each set, the change in the flexibility matrix relative to that of the reference or undamaged structure is computed and singular value decomposition is performed to estimate the number of nonzero singular values (NZV). The set that produces the smallest NZV is associated with healthy sensors whereas sensors that do not belong to that combination are suspected to be faulty. The performance of the proposed algorithm is illustrated using both simulated and experimental data obtained from a 3D modular truss structure monitored by sensors, some of which are faulty.
Security challenges and opportunities in adaptive and reconfigurable hardware (2011)

We present a novel approach to building hardware support for providing strong security guarantees for computations running in the cloud (shared hardware in massive data centers), while maintaining the high performance and low cost that make cloud computing attractive in the first place. We propose augmenting regular cloud servers with a Trusted Computation Base (TCB) that can securely perform high-performance computations. Our TCB achieves cost savings by spreading functionality across two paired chips. We show that making a Field-Programmable Gate Array (FPGA) a part of the TCB benefits security and performance, and we explore a new method for defending the computation inside the TCB against side-channel attacks.
Pyjamask: Block Cipher and Authenticated Encryption with Highly Efficient Masked Implementation (2020)

This paper introduces Pyjamask, a new block cipher family and authenticated encryption proposal submitted to the NIST lightweight cryptography standardization process. Pyjamask targets side-channel resistance as one of its main goal. More precisely, it strongly minimizes the number of nonlinear gates used in its internal primitive in order to allow efficient masked implementations, especially for high-order masking in software. Compared to other block ciphers, our proposal has thus among the smallest number of binary AND computations per input bit at the time of writing. Even though Pyjamask minimizes such an important criterion, it remains rather lightweight and efficient, thanks to a general bitslice construction that enables to computation of all nonlinear gates in parallel. For authenticated encryption, we adopt the provably secure AEAD mode OCB which has been extensively studied and has the benefit to offer full parallelization. Of course, other block cipher-based modes can be considered as well if other performance profiles are to be targeted. The paper first gives the specification of the Pyjamask block cipher and the associated AEAD proposal. We also provide a detailed design rationale for the block cipher which is guided by our aim of software efficiency in the presence of high-order masking. The security of the design is analyzed against most commonly known cryptanalysis techniques. We finally describe efficient (masked) implementations in software and provide implementation results with aggressive performances for masking of very high orders (up to 128). We also provide a rough estimation of the hardware performances which remain much better than those of an AES round-based implementation.
Repeated administration of adipose-derived mesenchymal stem cells added on beneficial effects of empagliflozin on protecting renal function in diabetic kidney disease rat (2023)

Combined ADMSCs-EMPA was superior to just one therapy for protecting kidney function and ultra-structural integrity in DKD rodents.
Tunable control of electromagnetically induced transparency in hybrid grapheme metamaterials (2018)

We propose a hybrid graphene/metamaterials device based on terahertz frequency. By placing the radiative and dark modes in the vertical and horizontal Si bars, we further demonstrate electromagnetically induced transparency (EIT), analogous to the atomic EIT. We theoretically investigate the strong interaction between graphene and EIT of the metamaterials. By varying the Fermi energy of graphene, the simulations show that graphene can actively modulate the transmission amplitude of EIT. Our results suggest that the demonstrated EIT in hybrid graphene metamaterials may offer new possibilities for applications in terahertz modulators and ultra-sensitive sensors.
