Channel based adaptive resource allocation at the MAC layer in UMTS TD-CDMA systems (2002)

We propose a scheduling strategy at the MAC level for the TDD/TCDMA UMTS third generation air interface. More precisely, we consider the uplink of a single-cell pedestrian outdoor scenario. Within this context we investigate the advantage of scheduling the different services that can be offered to the system, characterized by different quality and delay requirements, taking both the service priority and the channel state into account. The characteristics of the TDD/TCDMA transmission system, the power control algorithm and a frequency selective fading channel are considered in our approach, which is semi-analytical and allows the evaluation of the statistics of the frame error rate and the average transmitted power per data unit, which is a measure of efficiency from the energy management point of view. The performance of the scheduling algorithm we propose is compared to a more traditional scheduling approach which takes only the priority of services into account.
Security as a Service (SasS): Securing user data by coprocessor and distributing the data (2010)

In the world of computing, security and privacy issues are a major concern and cloud computing is no exception to these issues. In this paper we outline a security protocol called as Security as a Service (SasS). We provide a mechanism for achieving maximum security by leveraging the capabilities of a processor called a cryptographic coprocessor. Further we enhance the security of the encrypted data by distributing the data within the cloud, i.e. we divide the user data into pieces called as chunks. SasS protocol gives the user a chance to define the security of their data, by leaving the option of dividing the data into chunks in the user's hand. Based on the user requirement data will be made into chunks. Each chunk after encryption will be stored in a separate database. In this way we provide the maximum security to a user data. To our best knowledge, for the first time security is offered as a service to the user.
PP.38.13 (2015)

Objective: To explore the association between childhood risk factors and arterial stiffness in adulthood. Design and method: A baseline survey was carried out in 4623 school children aged 6–15 years in rural areas of Hanzhong city, Shaanxi in 1987. According to three measurements of systolic blood pressure (SBP) in 1987,1989 and 1992, high blood pressure group (HBP group) was defined as SBP equal or more than 75 percentile at same age and gender, with SBP < 50 percentile as normal blood pressure group (NBP group). The cohort were followed up again 26-years later(in 2013), At the same time, Blood biochemistry indexes were measured, including fasting glucose, uric acid and blood lipid. Brachial-ankle pulse wave velocity (baPWV) was recorded by noninvasive automatic waveform analyzer. Results: The follow-up rate was 71.6%. HBP group versus NBP group had higher incidence of hypertension (39.5% vs.18.0%, P = 0.001) and baPWV [(1337.2 ± 198.3) vs. (1271.7 ± 204.3) cm/s, P = 0.028] in this follow-up period. Correlation analysis indicated that the follow-up baPWV was positively correlated with childhood SBP and SBP, DBP, body mass index, heart rate, TC, LDL-C, TG, fasting glucose, uric acid in adulthood (all P < 0.05). In stepwise multivariate regression analysis, gender, family history of hypertension, SBP at both baseline and follow-up, fasting glucose and uric acid in adulthood were independent predictive factors of baPWV in adults. Conclusions: Higher SBP in children and adolescents, family history of hypertension and male gender may increase the risk of developing long-term arterial stiffness.
A new bacterial sphingophospholipid containing 3-aminopropane-1,2-diol (1972)

1. A new sphingophospholipid has been isolated from the bacterial fraction of sheep rumen contents. 2. This new lipid has been characterized as a ceramide phosphate moiety esterified to 3-aminopropane-1,2-diol through the primary alcohol group. 3. Mass spectrometry has shown the intact lipid to contain a vicinal hydroxyl amino grouping, and oxidation with periodate converts it quantitatively into a new phospholipid which is probably ceramide phosphorylglycolaldehyde. 4. The sphingophospholipid contains a mixture of saturated long-chain bases mainly with branched-chain alkyl groups, which are typical of a microbial origin. 5. A Gram-negative bacterium isolated from rumen contents contains about 30% of the new lipid in its phospholipids when grown in pure culture.
Decreased expression of heat shock protein 70 mRNA and protein after heat treatment in cells of aged rats. (1990)

The effect of aging on the induction of heat shock protein 70 (HSP70)-encoding gene expression by elevated temperatures was studied in cultures of lung- or skin-derived fibroblasts from young (5 mo) and old (24 mo) male Wistar rats. Although the kinetics of the heat shock response were found to be similar in the two age groups, we observed lower levels of induction of HSP70 mRNA and HSP70 protein in confluent primary lung and skin fibroblast cultures derived from aged animals. Additional experiments with freshly excised lung tissue showed a similar age-related decline in the heat-induced expression of HSP70.

Inter-vehicle information-fusion with shared perception information (2014)

Developing concepts for cooperative awareness was subject of several international research programs in the past years 2. The main concept for cooperative awareness is the communication of localization information enriched by situation specific content by meanwhile standardized messages like the Cooperative Awareness Message (CAM) in Europe or the Basic Safety Message (BSM) in the US. The concept of cooperative perception extends the state of the art concept of cooperative awareness by integrating perception information from infrastructure perception systems (IPS) <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> and vehicle perception systems (VPS) in the ego-vehicles environment model. In this paper three variants of the Covariance Intersection (CI) method used for state fusion in an Inter-Vehicle Information-Fusion (IV-IF) System are compared. The goal is to figure out which CI method out of the selection is the best choice for an active road safety application described in a recent publication, which was developed within the research project Ko-PER (cooperative perception).
Synthesis, Activity, and Molecular Modeling of New 2,4-Dioxo-5-(naphthylmethylene)-3-thiazolidineacetic Acids and 2-Thioxo Analogues as Potent Aldose Reductase Inhibitors (1998)

A series of 2,4-dioxo-5-(2-naphthylmethylene)-3-thiazolidineacetic acids and 2-thioxo analogues have been prepared as aldose reductase inhibitors. In vitro inhibitory activities of bovine lens aldose reductase were determined by a conventional method. 1-Naphthyl-substituted derivatives of the 2-thioxo series were the more potent inhibitors (IC50 congruent with 10 nM) with similar activity to that of Epalrestat. Structural analysis, especially by X-ray crystallography of two selected compounds, and molecular modeling comparisons with Zopolrestat were performed. These results provide explanations of the good activity of the inhibitor, the preference for 1-naphthyl-substituted compounds, and the nature of molecular interactions in these systems.
Reading board for magnetographs (1926)

This recording board was designed and constructed for use with the magnetograms obtained from the Eschenhagen variometer at the Toolangi Magnetic Observatory. The board is 30′′×12½×1′′ and carries a straight edge S which can move laterally through a distance of 1 inch. When the clamping nut C is released S can be traversed by hand, the rod R sliding freely in a hole bored in the end of S . When C is clamped to R , S is traversed by means of the nut N .
Imaging a BQM-74E Target Drone Using Coherent Radar Cross Section Measurements (1997)

ince the early 1980s and the advent of the modern computer, digital radar imaging has developed into a mature field. In this article, the specific problem of imaging a rotating target with a stationary radar is reviewed and built upon. The relative motion between the rotating target and the stationary radar can be used to create a circular synthetic aperture for imaging the target. Typically, an image is reconstructed by first reformatting the raw data onto a two-dimensional grid in the spatial frequency domain (commonly referred to as k-space) and then inverting into the spatial domain using a Fourier transform. This article focuses on a less popular reconstruction paradigm, tomographic processing, which can be used to coherently reconstruct the image incrementally as data become available. Both techniques suffer from sidelobe artifacts. It is shown that one-dimensional adaptive windowing can be applied during the reconstruction phase to reduce sidelobe energy while preserving mainlobe resolution in the image plane. The algorithms are applied to real and simulated radar cross section data.
Bis(allyl)ruthenium(IV) Complexes Containing Water‐Soluble Phosphane Ligands: Synthesis, Structure, and Application as Catalysts in the Selective Hydration of Organonitriles into Amides (2010)

The novel mononuclear ruthenium(IV) complexes [RuCl(2)(eta(3):eta(3)-C(10)H(16))(L)] [L=(meta-sulfonatophenyl)diphenylphosphane sodium salt (TPPMS) (2a), 1,3,5-triaza-7-phosphatricyclo[3.3.1.1(3, 7)]decane (PTA) (2b), 1-benzyl-3,5-diaza-1-azonia-7-phosphatricyclo[3.3.1.1(3, 7)]decane chloride (PTA-Bn) (2c), 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane (DAPTA) (2d), and 2,4,10-trimethyl-1,2,4,5,7,10-hexaaza-3-phosphatricyclo[3.3.1.1(3, 7)]decane (THPA) (2e)] have been synthesized by treatment of the dimeric precursor [{RuCl(mu-Cl)(eta(3):eta(3)-C(10)H(16))}(2)] (C(10)H(16)=2,7-dimethylocta-2,6-diene-1,8-diyl) (1) with two equivalents of the corresponding water-soluble phosphane. Reaction of 1 with one equivalent of the cage-type diphosphane ligand 2,3,5,6,7,8-hexamethyl-2,3,5,6,7,8-hexaaza-1,4-diphosphabicyclo[2.2.2]octane (THDP) allowed also the high-yield preparation of the dinuclear derivative [{RuCl(2)(eta(3):eta(3)-C(10)H(16))}(2)(mu-THDP)] (2f). All these new complexes have been analytically and spectroscopically (IR and multinuclear NMR) characterized. In addition, the structure of 2b, 2c, 2d, and 2f was unequivocally confirmed by X-ray diffraction methods. Complexes 2a-f are active catalysts for the selective hydration of nitriles to amides in pure aqueous medium under neutral conditions. The wide scope of this catalytic transformation has been evaluated by using the most active catalysts [RuCl(2)(eta(3):eta(3)-C(10)H(16))(THPA)] (2e) and [{RuCl(2)(eta(3):eta(3)-C(10)H(16))}(2)(mu-THDP)] (2f). Advantages of using MW versus conventional thermal heating are also discussed.
Dynamic interaction networks in a hierarchically organized tissue (2010)

Intercellular (between cell) communication networks maintain homeostasis and coordinate regenerative and developmental cues in multicellular organisms. Despite the importance of intercellular networks in stem cell biology, their rules, structure and molecular components are poorly understood. Herein, we describe the structure and dynamics of intercellular and intracellular networks in a stem cell derived, hierarchically organized tissue using experimental and theoretical analyses of cultured human umbilical cord blood progenitors. By integrating high-throughput molecular profiling, database and literature mining, mechanistic modeling, and cell culture experiments, we show that secreted factor-mediated intercellular communication networks regulate blood stem cell fate decisions. In particular, self-renewal is modulated by a coupled positive-negative intercellular feedback circuit composed of megakaryocyte-derived stimulatory growth factors (VEGF, PDGF, EGF, and serotonin) versus monocyte-derived inhibitory factors (CCL3, CCL4, CXCL10, TGFB2, and TNFSF9). We reconstruct a stem cell intracellular network, and identify PI3K, Raf, Akt, and PLC as functionally distinct signal integration nodes, linking extracellular, and intracellular signaling. This represents the first systematic characterization of how stem cell fate decisions are regulated non-autonomously through lineage-specific interactions with differentiated progeny.
Facile Phenylboronate Modification of Silica by a Silaneboronate (2012)

Macroscopic and colloidal silica surfaces were readily modified with alkoxysilaneboronate, IV, yielding silica surfaces with covalently bonded phenylboronic acid groups. XPS and neutron activation confirmed the presence of boron. The ability of these surfaces to specifically interact with polyols was demonstrated with polyol-coated latex and ARS, a dye that specifically couples to boronic acid groups immobilized on colloidal or macroscopic silica. This is a new, direct approach for introduction of phenylboronic acid groups onto silica surfaces.
Modellversuche an isolierter Epidermis zur Prüfung der Permeabilität der menschlichen Haut und der Kinetik des Penetrationsvorganges (1971)

Abstract Bei den mit Lösungen von Salicylsäure und Resorcin in Wasser und organischen Lösungsmitteln an isolierter Epidermis durchgeführten Untersuchungen hat sich gezeigt, daß für das Ausmaß der Penetration einer Substanz ihre effektive Konzentration in der Hornschicht entscheidend ist, die ihrerseits durch den Verteilungskoeffizienten bestimmt wird. Bei hohen Konzentrationen zeigen die organischen Lösungsmittel ein unterschiedliches Verhalten. Während z. B. beim Äthanol die Penetration aus wäßriger Lösung kontinuierlich zunimmt, weist die Penetration des Propanols bei einer Konzentration von etwa 50% ein Maximum auf und fällt danach stark ab. Die Salicylsäure übt auf das Penetrationsvermögen von organischen Lösungsmitteln einen penetrationsfördernden, das Resorcin einen penetrationshemmenden Einfluß aus.
Specific glycosaminoglycans support the inhibition of thrombin by plasminogen activator inhibitor 1 (1993)

In the absence of accessory components, plasminogen activator inhibitor 1 (PAI-1) rapidly forms equimolar, inactive complexes both with tissue-type (t-PA) and with urokinase-type (u-PA) plamsinogen activator. In the presence of either the glycoprotein vitronectin or the glycosaminoglycan heparin, PAI-1 is endowed with additional, efficient thrombin-inhibitory properties (Ehrlich et al., 1990, 1991a). Here, we have investigated the interaction between PAI-1, thrombin, and glycosaminoglycans in more detail. Inhibition of thrombin by PAI-1 was quantitatively analyzed in the presence of a wide range of concentrations of heparin, heparan sulfate, dermatan sulfate, chondroitin 4-sulfate, chondroitin 6-sulfate, keratan sulfate, and hyaluronic acid by measuring residual amidolytic activity. In addition, a qualitative analysis was performed by determining the formation of SDS-stable, equimolar complexes between thrombin and PAI-1 in the presence of various glycosaminoglycans. Heparin, at concentrations between 0.1 and 1 microgram/mL, significantly promoted thrombin inhibition by PAI-1 as well as SDS-stable complex formation. Suboptimal inhibition was observed with dermatan sulfate, chondroitin 4-sulfate, and heparan sulfate at concentrations that are at least 1 order of magnitude higher than that required for optimal inhibition in the presence of heparin. Virtually no inhibition of thrombin and SDS-stable complex formation was detected with any of the other glycosaminoglycans at concentrations between 0.1 and 1 microgram/mL.(ABSTRACT TRUNCATED AT 250 WORDS)

Molecular Design and Polymer Structure Control Based on Polymer Crystal Engineering. Topochemical Polymerization of 1,3-Diene Mono- and Dicarboxylic Acid Derivatives Bearing a Naphthylmethylammonium Group as the Countercation (2000)

The topochemical polymerization of the alkylammonium salts of (Z,Z)-, (E,Z)-, and (E,E)-1,3-diene mono- or dicarboxylic acids, i.e., of the muconic and sorbic acid derivatives, is described from the viewpoint of polymer crystal engineering. Not only the (Z,Z)- but also the (E,E)-derivatives polymerize to give a high molecular weight polymer in the crystalline state under UV irradiation when a naphthylmethylammonium moiety is introduced to these monomers as the countercation. NMR spectroscopy confirms the formation of the stereoregular meso- or erythro-diisotactic-trans-2,5-polymer during the polymerization, irrespective of the configuration of the monomers and the structure of the substituents. The single-crystal structure analysis of the naphthylmethylammonium salt of sorbic acid reveals the stacking of the diene moieties in the columns formed in the crystals, favorable for the topochemical polymerization. The photopolymerization reactivity and the stereochemistry of the resulting polymers are determined by the molecular packing in the crystals during the topochemical polymerization of the diene monomers.
The missing links : financial systems that work for the majority (1995)

In April 1995, ninety leaders of finance ministries, central banks, financial institutions, international development agencies, and Women's World Banking (WWB) participated in the WWB Global Policy Forum in India, to build actions that would open financial systems to the world's poor majority. The purpose was to pull together public and private financial leaders with the power to transform local and global financial systems in ways that will open access to millions of low income entrepreneurs. During the Policy Forum, leaders arrived at consensus on the approaches and actions needed, and committed to moving the recommendations into practice.
Time, pH, and size dependency of silver nanoparticle dissolution: the road to equilibrium (2017)

Oxidative dissolution has large implications for the environmental fate and toxicity of silver nanoparticles (AgNPs).
Propagation of electromagnetic stochastic beams in anisotropic turbulence (2014)

The effects of anisotropic, non-Kolmogorov turbulence on propagating stochastic electromagnetic beam-like fields are discussed for the first time. The atmosphere of interest can be found above the boundary layer, at high (more than 2 km above the ground) altitudes where the energy distribution among the turbulent eddies might not satisfy the classic assumption represented by the famous 11/3 Kolmogorov's power law, and the anisotropy in the direction orthogonal to the Earth surface is possibly present. Our analysis focuses on the classic electromagnetic Gaussian Schell-model beams but can either be readily reduced to scalar and/or coherent beams or generalized to other beam classes. In particular, we explore the effects of the anisotropic parameter on the spectral density, the spectral degree of coherence and on the spectral degree of polarization of the beam.
The Matricellular Protein Periostin Is Required for Sost Inhibition and the Anabolic Response to Mechanical Loading and Physical Activity (2009)

Periostin (gene Postn) is a secreted extracellular matrix protein involved in cell recruitment and adhesion and plays an important role in odontogenesis. In bone, periostin is preferentially expressed in the periosteum, but its functional significance remains unclear. We investigated Postn(-/-) mice and their wild type littermates to elucidate the role of periostin in the skeletal response to moderate physical activity and direct axial compression of the tibia. Furthermore, we administered a sclerostin-blocking antibody to these mice in order to demonstrate the influence of sustained Sost expression in their altered bone phenotypes. Cancellous and cortical bone microarchitecture as well as bending strength were altered in Postn(-/-) compared with Postn(+/+) mice. Exercise and axial compression both significantly increased bone mineral density and trabecular and cortical microarchitecture as well as biomechanical properties of the long bones in Postn(+/+) mice by increasing the bone formation activity, particularly at the periosteum. These changes correlated with an increase of periostin expression and a consecutive decrease of Sost in the stimulated bones. In contrast, mechanical stimuli had no effect on the skeletal properties of Postn(-/-) mice, where base-line expression of Sost levels were higher than Postn(+/+) and remained unchanged following axial compression. In turn, the concomitant injection of sclerostin-blocking antibody rescued the bone biomechanical response in Postn(-/-) mice. Taken together, these results indicate that the matricellular periostin protein is required for Sost inhibition and thereby plays an important role in the determination of bone mass and microstructural in response to loading.
Harmful and beneficial antibodies in immune thrombocytopenic purpura. (1994)

Two facts support the definition of idiopathic thrombocytopenic purpura (ITP) as an immune disorder. First, antibodies against platelets, which often appear after a viral infection, provoke the increased elimination of these cells. Viral disease may change the complex immune response of the host at different levels. In chronic ITP, the consequences of the dysregulated immune system are autoantibodies, primarily against platelet glycoprotein IIb/IIIa. Second, pooled immunoglobulins from healthy blood donors may influence the imbalanced immune response in ITP. The initial study dose of 5 x 0.4 g of intact 7S IgG/kg body weight can now be reduced to 2 x 0.4 g/kg body weight in the majority of patients. The possible mechanisms of action of intravenous immune globulin (IVIG) are reviewed and updated in this article. The combination of effects on the humoral and cellular immune responses using IVIG in concert with cytokines may open up new therapeutic possibilities.
