Antibacterial and antifungal LDPE films for active packaging (2014)

Active antimicrobial packaging is a promising form of active packaging that can kill or inhibit microorganism growth in order to maintain product quality and safety. One of the most common approaches is based on the release of volatile antimicrobial agents from the packaging material such as essential oils. Due to their highly volatile nature, the challenge is to preserve the essential oils during the high‐temperature melt processing of the polymer, while maintaining high antimicrobial activity for a desired shelf life. This study suggests a new approach in order to achieve this goal. Antimicrobial active films are developed based on low‐density polyethylene (LDPE), organo‐modified montmorillonite clays (MMT) and carvacrol (used as an essential oil model). In order to minimize carvacrol loss throughout the polymer compounding, a pre‐compounding step is developed in which clay/carvacrol hybrids are produced. The hybrids exhibit a significant increase in the d‐spacing of clay and enhanced thermal stability. The resulting LDPE/(clay/carvacrol) films exhibit superior and prolonged antibacterial activity against Escherichia coli and Listeria innocua , while polymer compounded with pure carvacrol loses the antibacterial properties within days. The films also present an excellent antifungal activity against Alternaria alternata , used as a model plant pathogenic fungus. Furthermore, infrared spectroscopy analysis of the LDPE/(clay/carvacrol) system displayed significantly higher carvacrol content in the film as well as a slower out‐diffusion of the carvacrol molecules in comparison to LDPE/carvacrol films. Thus, these new films have a high potential for antimicrobial food packaging applications due to their long‐lasting and broad‐spectrum antimicrobial efficacy. Copyright © 2014 John Wiley & Sons, Ltd.
Continuous cardiac output by femoral arterial thermodilution calibrated pulse contour analysis: Comparison with pulmonary arterial thermodilution (1999)

Femoral artery pulse contour CO correlates well with both COpa and COa even during substantial variations in vascular tone and hemodynamics. Additionally, CO determined by arterial thermodilution correlates well with COpa. Thus, COa can be used to calibrate COpc.

A high-performance MAC protocol for consumer broadband satellite systems (2009)

In this paper, an extended version of the CRDSA protocol proposed in and is presented. The enhanced CRDSA protocol, dubbed CRDSA++, extends the original CRDSA concept to more than two replicas (e.g. 4 or 5) and exploits power fluctuations in the received signal to further boost the performance of the CRDSA protocol. The paper provides a wide range of performance and sensitivity analysis with respect to the number of replicas and power unbalance. It is shown that a packet loss ratio (PLR) below 10-4 can be achieved with a normalized throughput in excess of 1 packet per slot. This represents a remarkable performance for an open loop random access (RA) scheme without any kind of access control over a medium shared by a large population of terminals. Finally, the paper also provides a preliminary discussion on the implementation aspects of the CRDSA++ RA scheme, as well as on the integration aspects with a DAMA protocol to support a wider range of service scenarios with improved MAC layer performance.

Response to Comment on "Synthesis of Ultra-Incompressible Superhard Rhenium Diboride at Ambient Pressure" (2007)

Dubrovinskaia et al . question our demonstration that rhenium diboride (ReB 2 ) is hard enough to scratch diamond. Here, we provide conclusive evidence of a scratch through atomic force microscopy depth profiling and elemental mapping. With high hardness, high-bulk modulus, and the ability to withstand extreme differential stress, ReB 2 and related materials should be investigated regardless of their cost, which is not prohibitive.
<i>Speech Processing and Synthesis Toolboxes</i> (2000)

According to the preface for this text, it ''...is based on material presented during the first semester of the postgraduate Masters Course in Sound and Vibration Studies at the Institute of Sound and Vibration Research in the University of Southampton, UK.'' At 518 pages and with a significant breadth of coverage, that first semester must be rather challenging. Nonetheless, having read this text at length, I intend to hand it to my own students with the simple directive, ''Read this.'' Paraphrasing the preface, the first semester of the ISVR Masters Course targets students with little or no prior knowledge of acoustics. Many of us find ourselves in the same situation when introducing new students to acoustics here in the U.S., and it is that application that this text serves most admirably.

1-Substituted-5-hydroxymethylimidazoles were prepared through green desulfurization of their 2-mercapto derivatives by the treatment of 30% hydrogen peroxide in the presence of a catalytic amount of transition metal catalysts.
Reduced burning and stinging associated with topical application of lactic acid 10% with strontium versus ammonium lactate 12%. (2013)

Burning and/or stinging is one of the most common concerns expressed by patients using topical therapies for treatment of dermatologic disorders. Topical lactic acid preparations often are used to treat dry scaly skin. In this study, we compared the level of burning/stinging reported by participants with application of lactic acid cream 10% containing strontium versus ammonium lactate lotion 12% and cetearyl alcohol lotion. The mean rating of burning/stinging reported for lactic acid cream 10% with strontium and cetearyl alcohol lotion was lower than ammonium lactate lotion 12% (P<.0001). Based on the study results, lactic acid cream 10% with strontium causes less burning/stinging than ammonium lactate lotion 12%.

Molecular Cloning of Plant Spermidine Synthases (1998)

Four cDNAs for spermidine synthase (SPDS), which converts the diamine putrescine to the higher polyamine spermidine using decarboxylated S-adenosylmethionine as the co-factor, were isolated from Nicotiana sylvestris, Hyoscyamus niger, and Arabidopsis thaliana. When the N.sylvestris SPDS cDNA was expressed in a SPDS-deficient E. coli mutant, the recombinant protein showed high SPDS activity, but did not have any spermine synthase activity. The plant SPDSs have molecular masses of about 34 kDa, possess the co-factor binding motifs which have been proposed for S-adenosylmethionine, and are more homologous in amino acid sequence to tobacco putrescine N-methyltransferase (PMT) than to SPDSs from mammals and E. coli. The SPDS gene is expressed in root, stem, and leaf in N.sylvestris, whereas the PMT gene is expressed only in root. The potential evolution of plant SPDS and PMT, and their evolutionary relationships with animal SPDS are discussed.
Effect of 1,25(OH)2D3 on the growth and apoptosis of breast cancer cell line MCF-7. (2000)

1,25(OH)2D3 can inhibit cell growth with G0/G1 arrest, enhance the proliferation inhibition action of adriamycin, and induce apoptosis which may result from the down-regulation of the anti-apoptotic bcl-2 protein.
Curcumin Inhibits Melanogenesis in Human Melanocytes (2011)

Plant derived compounds, as potentially safe and effective skin lightening agents (SLAs), have attracted great attention from many researchers. Curcumin is a plant-derived polyphenol, which has been reported to suppress melanogenesis in B16 melanoma cells. However, little is known about whether curcumin affects melanogenesis in cultured human melanocytes. In addition, the molecular mechanism for the antimelanogenic effects of curcumin remains largely unknown. The present study assessed the effects of curcumin on melanin synthesis, cellular tyrosinase activity, the expression of melanogenesis-related proteins (microphthalmia-associated transcription factor (MITF), tyrosinase, tyrosinase-related protein 1 and 2 (TRP-1, TRP-2)), and activation of melanogenesis-regulating signals including phosphatidylinositol 3-kinase (PI3K)/Akt/ glycogen synthase kinase 3 (GSK 3β), extracellular signal-regulated kinase (ERK) and p38 MAPK in human melanocytes. The results showed that the melanin content and tyrosinase activity, as well as the expression of melanogenesis-related proteins in human melanocytes, were significantly inhibited by curcumin in a dose dependent manner. In addition, PI3K/Akt/ GSK 3β, ERK and p38 MAPK were activated by curcumin, while inhibitors of these signals attenuated the inhibitory effects of curcumin on melanogenesis. These results suggest that curcumin inhibits melanogenesis in human melanocytes through activation of Akt/GSK 3β, ERK or p38 MAPK signaling pathways.
Agent-based Integration of General-Purpose Tools (1996)

Agent-Based Software Integration (ABSI) entails the development of intelligent soft-ware agents and knowledge-sharing protocols that enhance interoperability of multiple software packages. Although some past ABSI projects reported in the literature have been concerned with the integration of relatively large software frameworks from separate engi-neering disciplines, the discussion in this paper concerns the integration of general-purpose software utilities and hand-crafted tools. With such smaller-scale ABSI projects, it may be difficult to justify the expense of constructing an overall ontology for the application. There are cases, however, when the project involves general-purpose tools that manipulate the same general entity types (such as files) but at different levels of abstraction. In such cases it is appropriate to have ontologies appropriate for the general usage of each tool and constraint descriptions that enable the ontological specifications to be mapped across the various levels of abstraction. This paper discusses issues associated with this type of ABSI project and describes an example information management application associated with university course administration. For the information management application presented the key issues are the provision of standard agent wrappers for standard desktop infor-mation management tools and the design of standard ontologies describing information stored in relational databases as well as in structured text files. Examples of a conceptual model describing such a database ontology are presented in connection with the example application. It also suggested that a general planning agent, distinct from the notion of a facilitator agent, be employed in this context to assist in the use of various agents to manipulate information and move items from one data format to another. 1

Delta radiance transfer (2012)

Modular Radiance Transfer (MRT) is a recent technique for computing approximate direct-to-indirect transport. Scenes are dynamically constructed by warping and connecting simple shapes and compact transport operators are only precomputed on these simple shapes. MRT ignores fine-scale transport from "clutter" objects inside the scene, and computes light transport with reduced dimensional operators, which allows extremely high performance but can lead to significant approximation error. We present several techniques to alleviate this limitation, allowing the light transport from clutter in a scene to be accounted for. We derive additional low-rank delta operators to compensate for these missing light transport paths by modeling indirect shadows and interreflections from, and onto, clutter objects in the scene. We retain MRT's scene-independent precomputation and augment its scene-dependent initialization with clutter transport generation, resulting in increased accuracy without a performance penalty. Our implementation is simple, requiring a few small matrix-vector multiplications that generate a delta lightmap added to MRT's output, and does not adversely affect the performance benefits of the overall algorithm.
Diverse radar pulse-train with favourable autocorrelation and ambiguity functions (2003)

A coherent train of identical linear-FM pulses is a popular radar signal, mainly due to its good range and Doppler resolution. One of its drawbacks is the relatively high autocorrelation function (ACF) sidelobes. We show how to completely remove most of the sidelobes by diversifying the pulses through overlaying them with orthogonal coding. The technique applies to any other type of pulses - analog or digital.
Dynamic mechanical analysis of fiber reinforced composites (1980)

Abstract Dynamic mechanical and thermal properties were determined for unidirectional epoxy/glass composites at various fiber orientation angles. Resonant frequency and relative logarithmic decrement were measured as functions of temperature. In low angle and longitudinal specimens, a transition was observed above the resin glass transition temperature which was manifested mechanically as anadditional damping peak and thermally as a change in the coefficient of thermal expansion. The new transition was attributed to a heterogeneous resin matrix induced by the fiber. The temperature span of the glass‐rubber relaxation was found to broaden with decreasing orientation angle, reflecting the growth of fiber contribution and exhibiting behavior similar to that of Young's modulus. The change in resonant frequency through the glass transition was greatest for samples of intermediate fiber angle, demonstrating behavior similar to that of the longitudinal shear modulus.
The specific capsular polysaccharide of <i>Streptococcus pneumoniae</i> type 9V (1981)

The specific capsular polysaccharide produced by Streptococcus pneumoniae type 9V (American type 68) is composed of D-glucuronic acid (1 part), D-galactose (1 part), 2-acetamido-2-deoxy-D-mannose (1 part), D-glucose (2 parts), and O-acetyl (1.6 parts). Methylation, periodate oxidation, optical rotation, and nuclear magnetic resonance studies, and partial hydrolysis showed that the polysaccharide is an unbranched high molecular weight linear polymer of a partially O-acetylated pentasaccharide repeating unit having the structure indicated below. (Formula: see text).
Identifying Good Training Data for Self-Supervised Free Space Estimation (2016)

This paper proposes a novel technique to extract training data from free space in a scene using a stereo camera. The proposed technique exploits the projection of planes in the v-disparity image paired with Bayesian linear regression to reliably identify training image pixels belonging to free space in a scene. Unlike other methods in the literature, the algorithm does not require any prior training, has only one free parameter, and is shown to provide consistent results over a variety of terrains without the need for any manual tuning. The proposed method is compared to two other data extraction methods from the literature. Results of Support Vector classifiers using training data extracted by the proposed technique are superior in terms of quality and consistency of free space estimation. Furthermore, the computation time required by the proposed technique is shown to be smaller and more consistent than that of other training data extraction methods.
SOMATIC HYPERMUTATION OF IMMUNOGLOBULIN GENES (1996)

The relationship between somatic hypermutation and affinity maturation in the mouse is delineated. Recent work on the anatomical and cellular site of this process is surveyed. The molecular characteristics of somatic hypermutation are described in terms of the region mutated and the distinctive patterns of nucleotide changes that are observed. The results of experiments utilizing transgenic mice to find out the minimum cis-acting sequences required to recruit hypermutation are summarized. The hypothesis that V gene sequences have evolved in order to target mutation to certain sites but not others is discussed. The use that different species make of somatic hypermutation to generate either the primary or secondary B cell repertoire is considered. Possible molecular mechanisms for the hypermutation process and future goals of research are outlined.

Low levels of low molecular weight insulin-like growth factor-binding protein in patients with polycystic ovarian disease (1989)

Insulin-like growth factors IGF-I and IGF-II are bound to specific binding proteins in serum. The lower mol. wt binding protein (IGF-BP) has been detected in various tissues, including secretory endometrium and preovulatory follicles of the ovary. This group studied the circulating levels of IGF-BP in the serum of 23 patients with polycystic ovarian disease (PCOD) and found that one-third of them have a subnormal level. In comparison with PCOD patients with a normal level, those with a subnormal level had a higher degree of obesity and a tendency to be more hirsute. They also had a higher serum insulin concentration and testosterone/sex hormone-binding globulin (SHBG) ratio, but lower serum SHBG concentration than those with a normal IGF-BP level. PCOD is the second abnormal clinical condition, after insulinoma, in which subnormal serum IGF-BP concentrations have been reported. The significance of low serum IGF-BP levels to pathophysiology of PCOD remains to be elucidated by studies on local interaction between IGF-BP and insulin in the polycystic ovary.
<b>Lexikon der antiken Gestalten in den deutschen Texten des Mittelalters</b>. Hg. von Manfred Kern und Alfred Ebenbauer. 2003 (2004)

Dieses Lexikon verspricht, „erstmals einen systematischen Überblick über die in der mittelalterlichen deutschen Literatur von ca. 1050 bis 1350 genannten mythologischen und historischen Gestalten der griechisch-römischen Antike“ zu bieten (S. IX). Seine ausführlichen Begründungen dieses Ziels und einzelner Auswahlverfahren rücken historische Gegebenheiten, Kontextualisierungen und Funktionalisierungen ins Bewußtsein, verzichten dagegen dankenswerterweise auf bloße Kontinuitätsnachweise als Rechtfertigung der Anlage des Werks. Es geschieht im Sinne der behandelten Epoche, wenn nicht versucht wird, mythologische, historische und literarische Gestalten scharf voneinander abzuheben. Auch werden die Gegenstände des Lexikons in der Einleitung ausführlich unter mögliche mittelalterliche Perspektivierungen gerückt, etwa indem auf unterschiedliche mittelalterliche Nachahmungen, Deutungen oder Einordnungen der Antike eingegangen wird, so daß zum Beispiel rhetorische, typologische und realhistorische Muster oder Betrachtungsweisen als Möglichkeiten nebeneinander erscheinen.
A survey of DCRSi and D-2 technology (2002)

The DCRSi and D-2 advanced digital rotary-scan-recording digital formats require uniquely different technologies to achieve their performance requirements. The DCRSi is a transverse-scan format developed for use in general-purpose digital instrumentation recording applications under both benign and environmentally extreme conditions. The D-2 is a helical-scan format developed for use by the professional television industry to support the production and on-air broadcasting of program material for the studio environment. To satisfy their respective market needs, each product provides data rates in excess of 100 Mb/s and utilizes high-density recording techniques to achieve acceptable record times on conveniently sized cassettes. The DCRSi and D-2 tape formats, and the key technologies used to implement the current series of products, are surveyed. The selection of the D-2 platform as the basis for future development of a high-performance computer data peripheral is reviewed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Fibrosis is not just fibrosis - basement membrane modelling and collagen metabolism differs between hepatitis B- and C-induced injury (2016)

The main parameters to determine extracellular matrix biomarker levels are inflammation, fibrosis, and type of viral insult. Compared to CHC, CHB appears to induce a higher basement membrane turnover. This suggests that there are aetiology-dependent molecular signatures in liver fibrosis that could have pathogenic and diagnostic implications.
Linear estimation theory applied to the reconstruction of a 3-D vector current distribution (1990)

Linear estimation theory incorporating statistical a priori knowledge is applied to the inverse problem of reconstructing a static 3-D vector source field from another 3-D vector measurement field. The motivation for this development is to reconstruct 3-D electric current distributions from a set of magnetic measurements. Such a capability would be useful for the clinical determination of neural currents, for example. A simulation is presented to demonstrate the reconstruction of a class of simple nonbiological source objects, and to show the dependence of these reconstructions on the data taking configuration and the statistical a priori knowledge that is incorporated into the reconstruction process.
