Stabilisation d'ions Fe2+ dans le réseau de smectites ferrifères de synthèse (1998)

Smectites were synthesized from gels containing the cations: Si4+, Al3+, Fe2+, Mg2+, Na+ or Si4+, Al3+, Fe2+, Na+. Gels were prepared at 25°C in reducing conditions (glove box with nitrogen circulation, oxygen partial pressure = 10−6 atm). During synthesis, performed at 200°C for 41 days in teflon coated steel bombs put in a furnace, gas exchanges occur between bombs and laboratory atmospheres. The synthetic smectites are ferric beidellites with a Fe2+/Fetotal ratio ranging from 0 to 0.2. The octahedral Fe2+ ions in smectites appear stable over several months. Des smectites ont été synthétisées à partir de gels contenant les cations Si4+, Al3+, Fe2+, Mg2+, Na+ ou Si4+, Al3+, Fe2+, Na+, préparés en milieu réducteur à 25°C (boîte à gants à circulation d'azote, pression partielle d'oxygène = 10−6 atm). Durant la synthèse réalisée à 200°C pendant 41 jours dans des réacteurs en acier chemisé teflon, placés dans une étuve, des échanges de gaz se font entre les réacteurs et l'atmosphère du laboratoire. Les smectites synthétisées sont des beidellites ferrifères, dont le rapport Fe2+/Fetotal varie de 0 à 0,2. Les ions Fe2+ stabilisés dans les octaèdres des smectites ne s'oxydent pas au bout de plusieurs mois.
Reweighted LP decoding for LDPC codes (2010)

We introduce a novel algorithm for decoding binary linear codes by linear programming. We build on the LP decoding algorithm of Feldman et al. and introduce a post-processing step that solves a second linear program that reweights the objective function based on the outcome of the original LP decoder output. Our analysis shows that for some LDPC ensembles we can improve the provable threshold guarantees compared to standard LP decoding. We also show significant empirical performance gains for the reweighted LP decoding algorithm with very small additional computational complexity.

“Design and Development of Tractor Drawn Subsurface Manure and Seed Applicator” (2021)

Organic farming is now recognized as the best known alternative to the conventional agriculture, where cultivation and raising of crops and best quality of food is grown without any harm to the soil health, environmental and to the human being and microorganism present in the soil. Efficient organic nutrient supply to plant in adequate quantities to sustain most plant growth and yield while minimizing the environmental affected by the use of large quantities of inorganic fertilizers and pesticides which reduces the soil characteristics and productivity. Vermicom post is the major alternatives for organic farming with higher plant nutrients. Therefore, a tractor drawn subsurface manure and seed applicator was designed and developed in Farm Machinery and Power Engineering Department, G.B.P.U.A&amp; T Pantnagar, Uttara khand for placement of vermicom post (organic manure) at a depth of 50 to 200 mm below the soil surface. Firstly the frame for vermicom post and seed hopper was fabricated according to the desired capacity of vermicom post manure hopper. Six rectangular orifices were provided for delivery of manure at the middle of the bottom surface of the manure hopper. A counter shaft was fixed on the frame which was driven by the ground wheel and rotated the horizontal screw conveyor shaft of the manure hopper as well as seed hopper shaft by means of chain - sprocket arrangement. The velocity ratios between the ground wheel and the manure and fluted roller shaft were 2:1. The manure hopper shaft and fluted roller shaft were rotated at 14, 35 and 41 rpm when tractor forward speed 2, 4 and 6 km/h, respectively. Two depth control side wheels were provided below the frame to adjust the depth of cut of machine in field operation. A furrow opener was designed to penetrate into the soil at the desired depth and placed the vermicom post and seed below the soil surface.
Feature-Based Image Patch Approximation for Lung Tissue Classification (2013)

In this paper, we propose a new classification method for five categories of lung tissues in high-resolution computed tomography (HRCT) images, with feature-based image patch approximation. We design two new feature descriptors for higher feature descriptiveness, namely the rotation-invariant Gabor-local binary patterns (RGLBP) texture descriptor and multi-coordinate histogram of oriented gradients (MCHOG) gradient descriptor. Together with intensity features, each image patch is then labeled based on its feature approximation from reference image patches. And a new patch-adaptive sparse approximation (PASA) method is designed with the following main components: minimum discrepancy criteria for sparse-based classification, patch-specific adaptation for discriminative approximation, and feature-space weighting for distance computation. The patch-wise labelings are then accumulated as probabilistic estimations for region-level classification. The proposed method is evaluated on a publicly available ILD database, showing encouraging performance improvements over the state-of-the-arts.
Alkalization is responsible for antibacterial effects of corroding magnesium (2015)

Magnesium alloys are presently investigated as potential medical implant materials for temporary applications. Magnesium has been reported to have antibacterial activities and could therefore be used to prevent antibiotic treatment-resistant bacterial implant infections. For characterizing the effects of magnesium on infectious bacteria, bioluminescent S. aureus or P. aeruginosa were employed. The proliferation of both types of bacteria was suppressed in the presence of metallic magnesium and also in aqueous magnesium corrosion extracts. Of the two soluble corrosion products, magnesium ions were well tolerated while antibacterial activities correlated with increased pH levels of the supernatants. The alkaline pH alone was sufficient for the antibacterial effects which were completely abolished when the pH of the corrosion supernatants was neutralized. These results demonstrate that pH increases are necessary and sufficient for the antibacterial activity of metallic magnesium. In an animal model magnesium implants showed an enhanced but variable resistance to bacterial colonization.
Parenchymal volume analysis to assess longitudinal functional decline following partial nephrectomy (2023)

Longitudinal renal function following PN generally follows the normal ageing process. Significant renal comorbidities, age, warm ischaemia, and ipsilateral parenchymal atrophy were the most important predictors of ipsilateral functional decline following establishment of NBGFR.
From Painting to Widgets, 6-DOF and Bimanual Input Beyond Pointing (2019)

This chapter presents an approach to designing expressive three-dimensional (3D) user interfaces that make use of handheld input devices tracked in 3D space to go beyond a simple pointing metaphor. It considers a series of three examples that build upon each other to demonstrate how sophisticated 6-degree-of-freedom, beyond-pointing, bimanual virtual reality (VR) user interfaces can be built upon this framework. Although event-based user interfaces are common in desktop computing, there are several important nuances in VR. The state machine design pattern that developers suggest for programming VR interfaces helps programmers to track and respond appropriately to changes in context. The user interface to select curves must be flexible and controlled enough that users are able to indicate their desired selection regardless of the particular texture. The chapter describes how to implement contextual constraints to improve control of 3D User Interfaces.
Abstract 16907: Modification of Hemeoxygenase-1 Expression Enhances the Therapeutic Potency of CD34+ Cells in Ischemic Tissue Repair (2011)

The potency of cell-based therapy in ischemic tissue repair is limited by low viability and retention of transplanted cells. The hemeoxygenase system catabolizes heme cleavage and has been shown to exert cytoprotection via its anti-oxidative, -apoptotic, -inflammatory properties. HO-1, inducible in various pathologic states, has been shown to influence progenitor cell biology. We hypothesized that HO-1 over-expression enhances the therapeutic potency of CD34+ cells for ischemic tissue repair. CD34+ from healthy donors were enriched from the peripheral blood mononuclear cell fraction of healthy donors after G-CSF mobilization (Isolex 300i). Adenoviral transduction of HO-1/GFP or GFP led to a substantial increase of HO-1 expression (HO-1/18s RNA expression: 62-fold increase, protein expression: 20-fold increase; n=3). After allowing 48 hrs for target gene expression, CD34+ cells were FACS-sorted for GFP followed by overnight recovery in-vitro. A low-therapeutic dose (10^5 cells/kg) of HO-1+/GFP+ (HO-1) or GFP+ (GFP) CD34+ cells was locally injected into the border zone after complete ligation of the left coronary artery in 8-week-old, male nude mice (saline control: 2x 15 μl). At day 28, LV ejection fraction of mice treated with HO-1 over-expressing CD34+ cells was significantly improved (fractional shortening: saline 19±2%, HO-1 30±1%, GFP 24±1%; n=6-8/group, P&lt;0.01). This functional improvement can be explained by a preservation of the border-zone: the number of lectin+ capillaries was increased (lectin staining: saline 73±5/hpf, HO-1 99±4/hpf, GFP 79±7/hpf; n=7-8/group, P&lt;0.01) with the use of HO-1 modified CD34+ cells while lectin+/alpha-smooth-muscle actin+ structures indicative for resistance vessels remained unchanged (P=ns). Apoptosis of resident myocardial cells was attenuated (TUNEL staining: saline 69±5/hpf, HO-1 31±3, GFP 54±9, P&lt;0.05). As a result, the infarct size in mice treated with HO-1 modified cells was reduced (Masson-trichrome staining: saline 39±1%, HO-1 36±2%, GFP 42±1%; n=6-8/group, P&lt;0.05). Ongoing studies are addressing the underlying mechanism(s) on cellular basis as well as the clinical relevance. Conclusion: HO-1 gene modification enhances the therapeutic potency of CD34+ in ischemic tissue repair.
LP‐O: High‐Contrast‐Ratio Broad‐Angle LC Polarizing Beamsplitter (1998)

Abstract An efficient, broadband polarizing beam splitter based on birefringence of liquid crystals suitable for projection and communication systems was developed. Large aperture (about 2″), broad band (450nm–800nm or 1,000nm–1,800nm), wide acceptance angle (±10°), high splitting efficiency (contrast better than of 3,000:1 for the transmitted channel and 200:1–2,000:1 for the reflected one) with polarization axes matching the prism entrance and exit were achieved. Specially designed beveled edges contribute to beam splitter mechanical stability and manufacturability. The contrast remains better than 200:1 over the visible range at 45°C. Enhanced contrast for s‐polarization is obtained in a version that incorporates two reflecting surfaces within the prism. The device, used simultaneously as polarizer, analyzer, and combiner, is suitable for compact efficient high intensity image projector.
Inactivation of P. digitatum spore on Citrus unshiu by APDBD on driving roller conveyor (2014)

Defect structure and electrical properties of CaO-stabilized ZrO2 (2011)

The cubic fluorite-type solid solution of ZrO₂ containing 15 mole % CaO has been prepared by the hot-pressing process. The effects of annealing on the change.of lattice parameter, electrical properties, and density of the solid solution have been investigated. The lattice parameter of the cubic solid solution was found to depend on the heat treatment of the specimens. The decrease of lattice parameter with annealing temperature and time has been interpreted either in terms of the removal of interstitial oxygen ions from the." lattice or in terms of the inhomogeneous distribution of the CaO in the ZrO₂ lattice. The activation energy for conduction was also found to depend on the heat treatment of the specimens. The variation of activation energy with annealing temperature has been interpreted in terms of pairing and clustering of the oxygen vacancies with the substitutional Ca ions in the solid solution. The minimum activation energy obtained in the present investigation corresponded to the theoretically predicted activation energy for the migration of oxygen vacancies.
Semantic Vectors: a Scalable Open Source Package and Online Technology Management Application. (2008)

This paper describes the open source SemanticVectors package that efficiently creates semantic vectors for words and documents from a corpus of free text articles. We believe that this package can play an important role in furthering research in distributional semantics, and (perhaps more importantly) can help to significantly reduce the current gap that exists between good research results and valuable applications in production software. Two clear principles that have guided the creation of the package so far include ease-of-use and scalability. The basic package installs and runs easily on any Java-enabled platform, and depends only on Apache Lucene. Dimension reduction is performed using Random Projection, which enables the system to scale much more effectively than other algorithms used for the same purpose. This paper also describes a trial application in the Technology Management domain, which highlights some user-centred design challenges that we believe are also key to successful deployment of this technology. 1.
The complement cascade as a mediator of tissue growth and regeneration (2010)

Recent evidence has demonstrated that the complement cascade is involved in a variety of physiologic and pathophysiologic processes in addition to its role as an immune effector. Research in a variety of organ systems has shown that complement proteins are direct participants in maintenance of cellular turnover, healing, proliferation and regeneration. As a physiologic housekeeper, complement proteins maintain tissue integrity in the absence of inflammation by disposing of cellular debris and waste, a process critical to the prevention of autoimmune disease. Developmentally, complement proteins influence pathways including hematopoietic stem cell engraftment, bone growth, and angiogenesis. They also provide a potent stimulus for cellular proliferation including regeneration of the limb and eye in animal models, and liver proliferation following injury. Here, we describe the complement cascade as a mediator of tissue growth and regeneration.

An Uncommon Carboxyl‐Decorated Metal–Organic Framework with Selective Gas Adsorption and Catalytic Conversion of CO2 (2017)

A new three-dimensional (3D) framework, [Ni(btzip)(H<sub>2</sub> btzip)]⋅2 DMF⋅2 H<sub>2</sub> O (1) (H<sub>2</sub> btzip=4,6-bis(triazol-1-yl)isophthalic acid) as an acidic heterogeneous catalyst was constructed by the reaction of nickel wire and a triazolyl-carboxyl linker. Framework 1 possesses intersected 2D channels decorated by free COOH groups and uncoordinated triazolyl N atoms, leading to not only high CO<sub>2</sub> and C<sub>2</sub> H<sub>6</sub> adsorption capacity but also significant selective capture for CO<sub>2</sub> and C<sub>2</sub> H<sub>6</sub> over CH<sub>4</sub> and CO in 273-333 K. Moreover, 1 reveals chemical stability toward water. Grand Canonical Monte Carlo simulations confirmed the multiple CO<sub>2</sub> - and C<sub>2</sub> H<sub>6</sub> -philic sites. As a result of the presence of accessible Brønsted acidic COOH groups in the channels, the activated framework demonstrates highly efficient catalytic activity in the cycloaddition reaction of CO<sub>2</sub> with propylene oxide/4-chloromethyl-1,3-dioxolan-2-one/3-butoxy-1,2-epoxypropane into cyclic carbonates.
Comparative genomics allowed the identification of drug targets against human fungal pathogens (2011)

Our data show that the comparative genomics analysis of eight fungal pathogens enabled the identification of four new potential drug targets. The preferred profile for fungal targets includes proteins conserved among fungi, but absent in the human genome. These characteristics potentially minimize toxic side effects exerted by pharmacological inhibition of the cellular targets. From this first step of post-genomic analysis, we obtained information relevant to future new drug development.
Aerosolized aqueous dust extracts collected near a drying lake trigger acute neutrophilic pulmonary inflammation reminiscent of microbial innate immune ligands (2022)

Lung inflammatory responses to Salton Sea dusts are similar to acute innate immune responses, raising the possibility that microbial components are entrained in the dust, promoting inflammation. This effect highlights the health risks at drying terminal lakes from inflammatory components in dust emissions from exposed lakebed.

A lot of attention is paid to the development of dental caries resulting from nutritional anomalies.
Symmetric Coupling For Eddy Current Problems (2000)

In this paper a novel symmetric FEM-BEM-coupling for the E-based eddy current model is derived in a rigorous fashion. To that end the properties of potentials and boundary integral operators arising from a Stratton-Chu-type representation formula for the electric field in the nonconducting region are thoroughly analyzed in a Hilbert-space setting. It yields a variational problem with symmetric bilinear form that is coercive in the natural function spaces. Unknowns are the electric field inside the conductor and the equivalent surface current related to the magnetic field. Existence and uniqueness of solutions, and the convergence of conforming a finite element -- boundary element Galerkin discretizations immediately follow. In particular, schemes based on curl-conforming edge elements and divergence-conforming surface elements are examined.
Fractional Catalytic Pyrolysis of Hybrid Poplar Wood (2010)

Fractional catalytic pyrolysis is a selective in situ conversion of biopolymers into desired products. Fractional catalytic pyrolysis was used to convert the lignin fraction of hybrid poplar wood into high yields of cresols and phenols while the carbohydrate fraction was selectively converted into gaseous products. Ground air-dried biomass was fractionally pyrolyzed at 450−500 °C in a 2-in fluidized bed reactor. The total liquid, gas, and char/coke yields were 33%, 53%, and 12.5%, respectively. The low viscosity liquid products consisted of almost pure phenolics with minor carbohydrate decomposition products. The major liquid components were phenol, cresols, methyl substituted phenols, and small fractions of indene and substituted naphthalenes. The carbon and oxygen contents and high heating value (HHV) of the oil were 71%, 21%, and 30.5 MJ/kg, respectively. About 90 wt % of the gaseous products was carbon monoxide and carbon dioxide, and the rest was a mixture of hydrocarbons.
Myosin heavy chain of immature soleus muscle grafts adapts to hyperthyroidism more than to physical activity (1996)

The interaction of hyperthyroidism and the elements of physical activity on early regeneration of muscle grafts was investigated. Soleus muscle grafts were studied 15 days after graft operations in eu- and hyperthyroid rats. Hypotheses were tested regarding the adaptation of the myosin heavy chain (MHC) profile of grafts and nongrafted control muscles and whether the effect of hyperthyroidism would predominate over the opposing influence of recruitment and mechanical load on MHC of grafts. Denervation and myectomy of synergist muscles were employed to manipulate the elements of physical activity. Denervation decreased the expression of type I MHC, and hyperthyroidism furthered the shift toward a "fast" isoform profile. For example, in denervated grafts, type IIb was undetected in euthyroid rats and accounted for 31% of MHC in hyperthyroid rats. Compared with control muscles, grafts in the denervated and innervated-normal load groups demonstrated greater plasticity because the adaptive response of MHC to thyroid status was more pronounced. Hyperthyroidism predominated over the opposing influence of the elements of physical activity on the regulation of MHC expression in innervated plus overload grafts. For example, type I MHC was 86% of MHC profile of innervated plus overload grafts in euthyroid rats and was only 49% in hyperthyroid rats. In conclusion, a heightened plasticity for grafts was evidenced in denervated and innervated tissues, and the regulation of MHC by thyroid hormone predominated over that due to the elements of physical activity.
