Optimal spectrum access for a rechargeable cognitive radio user based on energy buffer state (2015)

This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests energy from natural resources, e.g., solar, wind and acoustic noise. We propose a probabilistic access strategy by the SU based on the number of packets at its energy queue. In particular, when the energy queue is in a certain state, the SU probabilistically uses a total number of energy packets that is at most equal to the number of packets at its energy queue. The probability of using certain amount of energy in a given state is optimizable. We investigate the effect of the energy arrival rate, the amount of energy per energy packet, and the capacity of the energy queue on the SU throughput under fading channels.
Protecting agents from malicious hosts using TPM. (2009)

Software agents represent a promising computing paradigm. They are an elegant technology to solve problems that can not be easily solved in other way. The Scientific Community has proved that the use of the software agents approach simplifies the solution of difierent type of traditional computing problems. A proof of this is that several important applications exist based on this technology. It is clear that software agents have so many benefits, but unfortunately, a lack of the appropriate security mechanisms for systems based on them represents a barrier for the widespread use of this paradigm in the industry. The application of the current security mechanisms is not trivial for agent based system developers, since they usually are not security experts and consequently do not count on the appropriate expertise. This paper presents a new protection infrastructure solving the problem known as malicious host in mobile agent systems. This protection infrastructure implements a secure protocol to migrate agents from host to host relying in hardware elements, particularly it is based on the recent advances in Trusted Platforms Modules (TPM) computing. In order to provide an easy way of using the proposed infrastructure we provide it by means of an extension to the Java Agent Development framework (JADE). Finally, the migrating protocol presented has been validated using
Dynamics of proteins at air-water and oil-water interfaces using novel Langmuir trough methods (2007)

Spread monolayers of β-lactoglobulin and bovine serum albumin and adsorbed films of lysozyme and β-lactoglobulin were studied at the oil (n-tetradecane) -water (O-W) and air-water (A-W) interfaces. In general, spread monolayers were more expanded at the O-W interface than at the A-W interface. Desorption rates from monolayers increased greatly with increasing interfacial pressure, π, but were still quite low until typical equilibrium adsorption π were exceeded. Desorption rates as a function of the energy barrier to desorption were similar at both types of interface. Adsorption kinetics of lysozyme at the A-W interface were in agreement with measurements obtained via ellipsometry. Spread and adsorbed films of β-lactoglobulin were subjected to dilatational expansion. The dynamics of the change in π were slower at the O-W interface, but for both interfaces the dynamics of the in-film relaxation processes were quite fast, diffusion from the bulk aqueous phase accounting for the long time-scale of the relaxation back to the equilibrium π for adsorbed films. A new type of Langmuir trough was used for these measurements.
A membrane-associated form of C-reactive protein is the galactose-specific particle receptor on rat liver macrophages. (1990)

Rat liver macrophages express a galactose-specific receptor which mediates endocytosis of particles or neuraminidase-treated blood cells. From rat serum we now have isolated and purified a galactose-specific lectin by affinity chromatography. Comparative analysis of this serum galactose-binding protein with the galactose-particle receptor protein purified from rat liver macrophages and with C-reactive protein (CRP) reveals close relation or identity of these proteins. An apparent m.w. of 30,000 was determined for all three proteins by SDS-PAGE under reducing conditions and m.w. of about 130,000 by native PAGE. All three proteins exhibit the same pentameric, ring-shaped structure in electron microscopy after negative staining. Antibodies raised against the serum galactose-binding protein or against the macrophage receptor cross-react. A mAb specific for rat neo-CRP labels liver macrophages but not hepatocytes and reacts with the isolated protein in a Western blot assay. Furthermore, the galactose-particle receptor can be functionally replaced by purified CRP: the binding capacity for neuraminidase-treated E of receptor-depleted liver macrophages can be restored by preincubation with purified rat CRP. We therefore conclude that CRP occurs as a membrane-associated protein constitutively expressed on liver macrophages functioning as a receptor mediating galactose-specific binding of particulate ligands.
Towards a Practical Brønsted Acid Catalyzed and Hantzsch Ester Mediated Asymmetric Reductive Amination of Ketones with Benzylamine (2010)

We report the use of benzylamine as the amine component in Hantzsch ester mediated and chiral Brnsted acid catalyzed enantioselective reductive aminations of ketones. The method is noteworthy because the benzyl group is easily removable, and amine product purification is achieved through Hantzsch ester oxidation product removal via basic hydrolysis.
EFFECT OF TENDON RELEASE AND DELAYED REPAIR ON THE STRUCTURE OF THE MUSCLES OF THE ROTATOR CUFF (2004)

Musculotendinous retraction induced by tendon release is associated with profound changes in the structure and function of the affected muscle. Vascularization, intramuscular pressure, and individual fiber composition are not markedly affected, and muscle fibers do not appear to degenerate. However, muscle atrophy, infiltration by fat cells, and an increase of interstitial connective tissue lead to impairment of the physiological properties of the muscle. These changes were irreversible under the conditions of this experiment with the repair technique used.
Some problems in the analysis of spatial pattern (1976)

Measurement of spatial pattern is of interest in many fields of study including forestry, ecology, archaeology, geography, astronomy, etc. Some new methods for measuring various aspects of spatial patterns formed by point events in the plane, are proposed.Sampling a population in the plane is usually carried out using either quadrat counts or distance measurements. Only the latter are used in this Thesis, as the methods introduced are aimed at the plant biologist or forester studying patterns formed by trees in a forest stand, where distance sampling is the easiest.The first method introduced is a new conditioned distance ratio method for analysing spatial pattern, which attempts to place patterns on an envisaged regular/random/aggregation scale. Instead of using an index as with most previous methods, a histogram of certain distances is formed, and analysis is based on viewing and hypothesis testing of this histogram.Two new robust estimators of the density of a forest stand are described, which are unbiased for a wide range of spatial patterns. The first estimator has a coefficient which varies according to some quantitative feature of the spatial pattern. This is a new idea for obtaining robust estimators.What constitutes a clumped or sparse area within a spatial pattern is very subjective. A method for the defining and marking of such areas is described. A computer package is used for the actual drawing of the clumped and sparse areas.The final topic to be discussed is that of two species in the plane. The spectral theory of two-dimensional, bivariate point processes is given, and then used to study the relationship between two species cohabiting in the plane.All the methods described are used on data, some of which are simulated, the rest being the coordinates of real trees in a forest stand.
Dual recognition of herpes simplex viruses by TLR2 and TLR9 in dendritic cells (2006)

Dendritic cells (DCs) express multiple Toll-like receptors (TLR) in distinct cellular locations. Herpes simplex viruses (HSV) have been reported to engage both the surface TLR2 and intracellular TLR9 in conventional DCs. However, the contributions of these TLRs in recognition of HSV and the induction of proinflammatory cytokines in DCs remain unclear. Here, we demonstrate that a rare population of HSV, both in laboratory strains and in primary clinical isolates from humans, has the capacity to activate TLR2. This virus population is recognized through both TLR2 and TLR9 for the induction of IL-6 and IL-12 secretion from bone marrow-derived DCs. Further, we describe a previously uncharacterized pathway of viral recognition in which TLR2 and TLR9 are engaged in sequence within the same DC. Live viral infection results in two additional agonists of TLR2 and TLR9. These results indicate that in cells that express multiple TLRs, pathogens that contain multiple pathogen-associated molecular patterns can be detected in an orchestrated sequence and suggest that the innate immune system in DCs is optimized to linking uptake and degradation of pathogens to microbial recognition.
Lyme borreliosis in transgenic mice tolerant to Borrelia burgdorferi OspA or B. (1995)

The evolution of Lyme borreliosis in transgenic mice tolerant to Borrelia burgdorferi outer surface proteins (Osps) A or B was assessed to investigate the role of immunity to OspA or B in infection and pathogenesis of Lyme disease. Antibodies to OspA or B protect immunocompetent C3H/HeJ or C.B.17 severe combined immunodeficient (scid) mice from challenge with B. burgdorferi. Moreover, arthritis in infected C3H mice resolves with the rise of high titers of B. burgdorferi specific antibodies, including OspA and B, whereas disease persists in scid mice--suggesting that the regression of arthritis may be due to the development of borreliacidal OspA or B antibodies. To evaluate the course of Lyme borreliosis in OspA or B tolerant mice we developed transgenic mice that expressed OspA or B under control of the major histocompatibility complex (MHC) class I promoter. Mice carrying OspA or B transgenes on a C3H/HeJ (C3H, disease-susceptible) or C57BL/6 (B6, disease-resistant) background, immunized with OspA or B, did not mount a humoral or cellular immune response to OspA or B, respectively, but responded normally to other B. burgdorferi antigens. The evolution of Lyme borreliosis, including infection and the development of arthritis and carditis, was similar in transgenic and nontransgenic littermates suggesting that an OspA or B immune response is not singularly involved in either the genesis or regression of Lyme disease in C3H or B6 mice.
Field Validation of the Los Angeles Motor Scale as a Tool for Paramedic Assessment of Stroke Severity (2017)

Effects of Film Thickness of ALD-Deposited Al2O3, ZrO2 and HfO2 Nano-Layers on the Corrosion Resistance of Ti(N,O)-Coated Stainless Steel (2023)

The goal of this stydy was to explore the potential of the enhanced corrosion resistance of Ti(N,O) cathodic arc evaporation-coated 304L stainless steel using oxide nano-layers deposited by atomic layer deposition (ALD). In this study, we deposited Al<sub>2</sub>O<sub>3</sub>, ZrO<sub>2</sub>, and HfO<sub>2</sub> nanolayers of two different thicknesses by ALD onto Ti(N,O)-coated 304L stainless steel surfaces. XRD, EDS, SEM, surface profilometry, and voltammetry investigations of the anticorrosion properties of the coated samples are reported. The amorphous oxide nanolayers homogeneously deposited on the sample surfaces exhibited lower roughness after corrosion attack compared to the Ti(N,O)-coated stainless steel. The best corrosion resistance was obtained for the thickest oxide layers. All samples coated with thicker oxide nanolayers augmented the corrosion resistance of the Ti(N,O)-coated stainless steel in a saline, acidic, and oxidising environment (0.9% NaCl + 6% H<sub>2</sub>O<sub>2</sub>, pH = 4), which is of interest for building corrosion-resistant housings for advanced oxidation systems such as cavitation and plasma-related electrochemical dielectric barrier discharge for breaking down persistent organic pollutants in water.
Comparative Proteomic Analysis of Streptococcus suis Biofilms and Planktonic Cells That Identified Biofilm Infection-Related Immunogenic Proteins (2012)

Streptococcus suis (SS) is a zoonotic pathogen that causes severe disease symptoms in pigs and humans. Biofilms of SS bind to extracellular matrix proteins in both endothelial and epithelial cells and cause persistent infections. In this study, the differences in the protein expression profiles of SS grown either as planktonic cells or biofilms were identified using comparative proteomic analysis. The results revealed the existence of 13 proteins of varying amounts, among which six were upregulated and seven were downregulated in the Streptococcus biofilm compared with the planktonic controls. The convalescent serum from mini-pig, challenged with SS, was applied in a Western blot assay to visualize all proteins from the biofilm that were grown in vitro and separated by two-dimensional gel electrophoresis. A total of 10 immunoreactive protein spots corresponding to nine unique proteins were identified by MALDI-TOF/TOF-MS. Of these nine proteins, five (Manganese-dependent superoxide dismutase, UDP-N-acetylglucosamine 1-carboxyvinyltransferase, ornithine carbamoyltransferase, phosphoglycerate kinase, Hypothetical protein SSU05_0403) had no previously reported immunogenic properties in SS to our knowledge. The remaining four immunogenic proteins (glyceraldehyde-3-phosphate dehydrogenase, hemolysin, pyruvate dehydrogenase and DnaK) were identified under both planktonic and biofilm growth conditions. In conclusion, the protein expression pattern of SS, grown as biofilm, was different from the SS grown as planktonic cells. These five immunogenic proteins that were specific to SS biofilm cells may potentially be targeted as vaccine candidates to protect against SS biofilm infections. The four proteins common to both biofilm and planktonic cells can be targeted as vaccine candidates to protect against both biofilm and acute infections.

Impact and Sliding Wear Properties of Single Layer, Multilayer and Nanocomposite Physical Vapour Deposited (PVD) Coatings on the Plasma Nitrided Low-Alloy 42CrMo4 Steel (2012)

Current paper handles the comparison of impact wear and sliding wear properties of the hard PVD single layer TiN and Ti(C,N), multilayer (Ti,Al)N and nanocomposite FiVIc® coatings on the plasma nitrided low-alloy 42CrMo4 steel. All the studied coatings demonstrated a relatively high impact wear resistance at the low (104) and medium (105) number of impacts, however, all the studied coatings vanished at the high number of impacts (106). Most extensive wear among the coatings during the sliding wear test was observed for the (Ti,Al)N coating, the FiVIc® showed the least extensive wear; the most extensive wear of the counterbody (hardened steel ball) was registered for the (Ti,Al)N coating, the lowest – for the FiVIc® and Ti(C,N) coatings. The principle wear mechanism of coatings was tribooxidation and mild abrasion, of the counterbody – plastic deformation
IUI-TextVis 2015 (2015)

Analyzing text documents has been a key research topic in many areas. Countless approaches have been proposed to tackle this problem, and they are largely categorized into fully automated approaches (via statistical techniques) or human-involved exploratory ones (via interactive visualization). The primary purpose of this workshop is to bring together researchers from both sides and provide them with opportunities to discuss ways to harmonize the power of these two complementary approaches. The combination will allow us to push the boundary of text analytics. The detailed workshop schedule, proceedings, and agenda will be available at http://www.textvis.org.

Topical Ranibizumab inhibits inflammatory corneal hem‐ and lymphangiogenesis (2012)

Ranibizumab is a potent inhibitor of inflammatory corneal hemangiogenesis and lymphangiogenesis in vivo with a direct inhibitory effect on both endothelial cell types in vitro. This study for the first time demonstrates an inhibitory effect of Ranibizumab on lymphatic vessels which could have a wider range of clinical applications.
Autophagy in Atherosclerosis (2009)

Autophagy is a reparative, life-sustaining process by which cytoplasmic components are sequestered in double-membrane vesicles and degraded on fusion with lysosomal compartments. A growing body of evidence suggests that autophagy is stimulated in advanced atherosclerotic plaques by oxidized lipids, inflammation, and metabolic stress conditions. However, despite the increasing interest in autophagy in various pathophysiological situations such as neurodegeneration, cancer, and cardiac myopathies, the process remains an underestimated and overlooked phenomenon in atherosclerosis. As a consequence, its role in plaque formation and stability is poorly understood. Most likely, autophagy safeguards plaque cells against cellular distress, in particular oxidative injury, by degrading damaged intracellular material. In this way, autophagy is antiapoptotic and contributes to cellular recovery in an adverse environment. An interesting observation is that basal autophagy can be intensified by specific drugs. Excessively stimulated autophagic activity is capable of destroying major proportions of the cytosol, leading finally to type II programmed cell death that lacks several hallmarks of apoptosis or necrosis. Because atherosclerosis is an inflammatory disorder of the arterial intima, pharmacological approaches could be developed to stabilize vulnerable, rupture-prone lesions through selective induction of macrophage autophagic death.
Local Delivery of Human Tissue Kallikrein Gene Accelerates Spontaneous Angiogenesis in Mouse Model of Hindlimb Ischemia (2001)

HK gene delivery enhances the native angiogenic response to ischemia. Angiogenesis gene therapy with HK might be applicable to peripheral occlusive vascular disease.
Zero shot prediction of video quality using intrinsic video statistics (2014)

We propose a no reference (NR) video quality assessment (VQA) model. Recently, ‘completely blind’ still picture quality analyzers have been proposed that do not require any prior training on, or exposure to, distorted images or human opinions of them. We have been trying to bridge an important but difficult gap by creating a ‘completely blind’ VQA model. The principle of this new approach is founded on intrinsic statistical regularities that are observed in natural vidoes. This results in a video ‘quality analyzer’ that can predict the quality of distorted videos without any external knowledge about the pristine source, anticipated distortions or human judgments. Hence, the model is zero shot. Experimental results show that, even with such paucity of information, the new VQA algorithm performs better than the full reference (FR) quality measure PSNR on the LIVE VQA database. It is also fast and efficient. We envision that the proposed method is an important step towards making real time monitoring of ‘completely blind’ video quality feasible.
Unprecedented formation of η4-(vinylketene)iron complexes from η4-(diene)iron complexes and aromatic compounds in the presence of a Lewis acid (2015)

A novel and unprecedented formation of η(4)-(vinylketene)iron complexes from η(4)-(diene)iron complexes is described herein. Treatment of η(4)-(diene)iron complexes with a Lewis acid such as GaCl3 or AlCl3 in the presence of aromatic compounds under a CO atmosphere affords η(4)-(vinylketene)iron complexes via electrophilic aromatic substitution.
Associations between Acoustic Features of Maternal Speech and Infants’ Emotion Regulation following a Social Stressor (2021)

Abstract Caregiver voices may provide cues to mobilize or calm infants. This study examined whether maternal prosody predicted changes in infants’ biobehavioral state during the Still Face, a stressor in which the mother withdraws and reinstates social engagement. Ninety-four dyads participated in the study (infant age 4-8 months). Infants’ heart rate and respiratory sinus arrhythmia (measuring cardiac vagal tone) were derived from an electrocardiogram (ECG). Infants’ behavioral distress was measured by negative vocalizations, facial expressions, and gaze aversion. Mothers’ vocalizations were measured with spectral analysis and spectro-temporal modulation using a two-dimensional fast Fourier transformation of the audio spectrogram. High values on the maternal prosody composite were associated with decreases in infants’ heart rate (β=-.26, 95% CI: [-.46, -.05]) and behavioral distress (β=-.20, 95% CI: [-.38, -.02]), and increases in cardiac vagal tone in infants whose vagal tone was low during the stressor (1 SD below mean β=.39, 95% CI: [.06, .73]). High infant heart rate predicted increases in the maternal prosody composite (β=.18, 95% CI: [.03, .33]). These results suggest specific vocal acoustic features of speech that are relevant for regulating infants’ biobehavioral state and demonstrate mother-infant bi-directional dynamics.
Effects of Microgravity and Clinorotation on the Virulence of Klebsiella, Streptococcus, Proteus, and Pseudomonas (2016)

Abstract To evaluate effects of microgravity on virulence, we studied the ability of four common clinical pathogens— Klebsiella , Streptococcus , Proteus , and Pseudomonas —to kill wild type Caenorhabditis elegans ( C. elegans) nematodes at the larval and adult stages. Simultaneous studies were performed utilizing spaceflight, rotation in a 2D clinorotation device, and static ground controls. Nematodes, microbes, and growth media were separated until exposed to true or modeled microgravity, then mixed and grown for 48 hours. Experiments were terminated by paraformaldehyde fixation, and optical density measurements were used to assay residual microorganisms. Spaceflight was associated with reduced virulence for Klebsiella and Streptococcus , but had negligible effect on Enterococcus and Pseudomonas. Clinorotation generated very different results with all four organisms showing significantly reduced virulence. We conclude that clinorotation is not a consistent model of the changes that actually occur under microgravity conditions. Further, bacteria virulence is unchanged or reduced, not increased during spaceflight.
