Scattering rate calculations in two-dimensional $\mathrm{Si}∕{\mathrm{Si}}_{1\ensuremath{-}x}{\mathrm{Ge}}_{x}$ systems have typically been restricted to rectangular Ge profiles at interfaces between layers. Real interfaces, however, may exhibit diffuse Ge profiles either by design or as a limitation of the growth process. It is shown here that alloy disorder scattering dramatically increases with Ge interdiffusion in (100) and (111) $n$-type quantum wells, but remains almost constant in (100) $p$-type heterostructures. It is also shown that smoothing of the confining potential leads to large changes in subband energies and scattering rates, and a method is presented for calculating growth process tolerances.
Regulation of the Formyl Peptide Receptor 1 (FPR1) Gene in Primary Human Macrophages (2012)

The formyl peptide receptor 1 (FPR1) is mainly expressed by mammalian phagocytic leukocytes and plays a role in chemotaxis, killing of microorganisms through phagocytosis, and the generation of reactive oxygen species. A large number of ligands have been identified triggering FPR1 including formylated and non-formylated peptides of microbial and endogenous origin. While the expression of FPR1 in neutrophils has been investigated intensively, knowledge on the regulation of FPR1 expression in polarized macrophages is lacking. In this study we show that primary human neutrophils, monocytes and resting macrophages do express the receptor on their cell surface. Polarization of macrophages with IFNγ, LPS and with the TLR8 ligand 3M-002 further increases FPR1 mRNA levels but does not consistently increase protein expression or chemotaxis towards the FPR1 ligand fMLF. In contrast, polarization of primary human macrophages with IL-4 and IL-13 leading to the alternative activated macrophages, reduces FPR1 cell surface expression and abolishes chemotaxis towards fMLF. These results show that M2 macrophages will not react to triggering of FPR1, limiting the role for FPR1 to chemotaxis and superoxide production of resting and pro-inflammatory M1 macrophages.

The use of fatty acid methyl ester analysis (FAME) for the identification of heterotrophic bacteria present on three mural paintings showing severe damage by microorganisms (1999)

Mural paintings in Carmona (Spain), Herberstein (Austria) and Greene (Germany), showing visible deterioration by microorganisms, were sampled to investigate the biodiversity of the heterotrophic bacteria present. Four hundred twenty-eight bacterial strains were isolated from which 385 were characterized by fatty acid methyl ester analysis (FAME). The isolates were grouped into 41 clusters on the basis of their FAME profiles, 20 isolates remained ungrouped. The majority (94%) of the isolates comprised the Gram-positive bacteria and the main clusters were identified as Bacillus sp., Paenibacillus sp., Micrococcus sp., Arthrobacter sp. and Staphylococcus sp. Other clusters contain nocardioform actinomycetes and Gramnegative bacteria, respectively. A cluster of the latter contained extreme halotolerant bacteria isolated in Herberstein. The FAME profiles of this cluster showed a high similarity with Halomonas.

Properties of all YBa2Cu3O7 Josephson edge junctions prepared by <i>in</i> <i>situ</i> laser ablation deposition (1991)

Thin-film YBa2Cu3O7-YBa2Cu3O7 edge junctions of 0.4×10 μm2 cross section were prepared in situ by a multistep laser ablation deposition process. The fabrication time was about 3 h and the yield of good devices was 50%. Typical junctions reached zero resistance at 72 K and had a critical current density Jc of 300 A/cm2 at 70 K. Their Jc as a function of temperature increased slowly with decreasing temperature down to 65 K and much faster below it. In the region of low Jc we observed suppression of the critical current by a magnetic field. Under microwave radiation clear Shapiro steps were observed whose magnitude versus the microwave field agreed qualitatively with the resistively shunted junction model of a current biased junction.
Selbsteinstellende klassische Regler mit Fuzzy-Logik (1994)

Selftuning of classical PI-controllers for processes without known mathematical models is achieved by applying heuristic fuzzy rules. Step changes of the reference input are used to assess control performance in terms of overshoot, rise time and settling time of the step response. Similar to the strategy of an experienced plant operator, a fuzzy logic «supervision and tuning module» can conclude from these features, which changes of the controller parameters will improve control behaviour. The concept was tested in simulation series with Matlab/Simulink. Results show the benefits of the proposed fuzzy tuning module applied to 8 different simulated test plants
Association between Transcriptional Activity, Local Chromatin Structure, and the Efficiencies of Both Subpathways of Nucleotide Excision Repair of Melphalan Adducts (2009)

The repair of melphalan-induced N-alkylpurine monoadducts and interstrand cross-links was examined in different repair backgrounds, focusing on four genes (beta-actin, p53, N-ras, and delta-globin) with dissimilar transcription activities. Adducts were found to be substrates for both global genome repair (GGR) and transcription-coupled repair (TCR), with TCR being less efficient than GGR. In nucleotide excision repair-deficient cells, adducts accumulated to similar levels in all four genes. The repair efficiency in different gene loci varied in a qualitatively and quantitatively similar way in both GGR-deficient and TCR-deficient backgrounds and correlated with transcriptional activity and local chromatin condensation. No strand-specific repair was found in GGR(+)/TCR(+) cells, implying that GGR dominated. Adducts were lost over two sharply demarcated phases: a rapid phase resulting in the removal within 1 hour of up to approximately 80% of the adducts, and a subsequent phase with t(1/2) approximately 36 to 48 hours. Following pretreatment of cells with alpha-amanitin, the rate of transcription, the state of chromatin condensation, and the repair efficiencies (both TCR and GGR) of the transcribed beta-actin, p53, and N-ras genes became similar to those of the nontranscribed delta-globin gene. In conclusion, a continuous, parallel variation of the state of transcription and local chromatin condensation, on one hand, and the rates of both GGR and TCR, on the other hand, have been shown.
Effect of frame size on energy consumption in wireless image sensor networks (2012)

Wireless sensor networks composed of camera-enabled source nodes can provide visual information of an area of interest, potentially enriching monitoring applications. While few bytes can represent scalar data, even low-resolution still images may require thousand of bytes, turning data fragmentation into a relevant design issue. Different optimization approaches have been proposed in recent years to achieve energy saving in wireless image sensor networks. However, the impact of image fragmentation upon the adopted MAC technology has been neglected in most cases. In this work we investigate the effect of frame size on image transmissions over wireless sensor networks, linking the maximum frame size, the useful payload and the frame error rate effects. Additionally, we discuss different approaches for transmissions of DWT-based encoded images and the impact of inserting application-specific information into the frame header. We believe that our discussions can contribute to the advance of the design of wireless image sensor networks.
Aspirin and aspirin‐caffeine in postpartum pain relief (1978)

In two double-blind randomized, balanced, single oral dose studies with 140 women, a combination of 800 mg aspirin and 64 mg caffeine (aspirin-caffeine) was compared to 650 mg aspirin and to placebo. In patients with moderate to severe uterine or episiotomy pain, there was greater analgesic response with active drugs when the initial pain intensity was more severe. In patients with severe episiotomy pain, aspirin-caffeine was more effective than 650 mg aspirin (p less than 0.05) at the second and third hours. There was no difference between analgesic effects of aspirin and aspirin-caffeine in women with severe uterine pain.
Role of Binding Site Loops in Controlling Nitric Oxide Release:  Structure and Kinetics of Mutant Forms of Nitrophorin 4<sup>,</sup> (2004)

Nitrophorins are ferric heme proteins that transport nitric oxide (NO) from blood-sucking insects to victims. NO binding is tighter at lower pH values, as found in the insect salivary gland, and weaker at the pH of the victim's tissue, facilitating NO release and subsequent vasodilation. Previous structural analyses of nitrophorin 4 (NP4) from Rhodnius prolixus revealed a substantial NO-induced conformational change involving the A-B and G-H loops, which rearrange to desolvate the distal pocket and pack nonpolar residues against the heme-ligated NO. Previous kinetic analyses revealed a slow, biphasic, and pH-dependent NO release, which was proposed to be associated with loop movements. In this study, we created NP4 mutants D30A and D30N (A-B loop), D129A/L130A (G-H loop), and T121V (distal pocket). Eight crystal structures were determined, including complexes with NO, NH(3), and imidazole, to resolutions as high as 1.0 A. The NO-induced conformational change is largely abolished in the loop mutants, but retained in T121V. Kinetic analyses using stopped-flow spectroscopy revealed the pH dependence for NO release is eliminated for D129A/L130A, considerably reduced for D30A and D30N, but retained for T121V. NO association rates were increased 2-5-fold for T121V, but were unchanged in the loop mutants. Taken together, our findings demonstrate that the pH dependency for NO release is linked to loop dynamics and that solvent reorganization is apparently rate-limiting for formation of the initial iron-nitrosyl bond. Interestingly, the multiphasic kinetic behavior of rNPs was not affected by mutations, and its cause remains unclear.
Influence of erythropoietin on microvesicles derived from mesenchymal stem cells protecting renal function of chronic kidney disease (2015)

There was a dose-dependent increase in the level of EPO-MVs within the range of 1-100 IU/ml EPO. Although both MSC-MVs and EPO-MVs protect the kidney from fibrosis-related damage, there is a superior effect of EPO-MVs.
Movie2Comics: Towards a Lively Video Content Presentation (2012)

As a type of artwork, comics is prevalent and popular around the world. However, despite the availability of assistive software and tools, the creation of comics is still a labor-intensive and time-consuming process. This paper proposes a scheme that is able to automatically turn a movie clip to comics. Two principles are followed in the scheme: 1) optimizing the information preservation of the movie; and 2) generating outputs following the rules and the styles of comics. The scheme mainly contains three components: script-face mapping, descriptive picture extraction, and cartoonization. The script-face mapping utilizes face tracking and recognition techniques to accomplish the mapping between characters' faces and their scripts. The descriptive picture extraction then generates a sequence of frames for presentation. Finally, the cartoonization is accomplished via three steps: panel scaling, stylization, and comics layout design. Experiments are conducted on a set of movie clips and the results have demonstrated the usefulness and the effectiveness of the scheme.

In accordance with the broad scope of the book's contents, physicists at universities, research institutes and in industry, physics students, and even physicians will benefit greatly from it.
Representation of non-manifold objects through decomposition into nearly manifold parts (2003)

ABSTRACT In our previous work [2], we have shown that a non-manifold,mixed-dimensional object described by simplicial complexes canbe decomposed in a unique way into regular components, all be-longing to a well-understood class. Based on such decomposition,we deﬁne here a two-level topological data structure for represent-ing non-manifold objects in any dimension: the ﬁrst level repre-sents components; while the second level represents the connectiv-ity relation among them. The resulting data structure is compactand scalable, allowing for the efﬁcient treatment of singularitieswithout burdening well-behaved parts of a complex with excessivespace overheads. Categories and Subject Descriptors I.3.5 [ Computer Graphics ]: Computational Geometry and ObjectModeling; I.3.6 [ Computer Graphics ]: Metodologies and Tech-niques General Terms Data structures Keywords Non-manifold modeling, simplicial complexes 1. INTRODUCTION A manifold object [with boundary] is a subset of the Euclideanspace for which the neighborhood of each point is locally equiv-alent [either] to an open ball [or to a closed half-space]. Objectsthat do not fulﬁll this property at one or more points are called
Performance evaluation of server virtualization in data center applications (2010)

One of the important targets in new generation data centers is minimizing the cost through efficient use of available resources. Virtualization is a new technology that provides an opportunity for extension of independent virtual resources based on available physical systems. This paper evaluates performance of virtualized versus non-virtualized servers in data center applications. We have presented a tile based evaluation based on heterogeneous workloads to compare several key parameters and demonstrate effectiveness of virtualization techniques. Moreover, we have evaluated the virtualized server models using V-Motion techniques and maximum sever consolidation. Results of evaluation for different criteria confirm that server virtualization technique has high throughput and CPU usage as well as good performance with noticeable agility. Experimental results which are obtained through our prototype model demonstrate that server virtualization can significantly reduces resource consumption while improves system performance. Obtained results certify that server virtualization can be a strategic decision for saving the investment, increasing service performance and creating new virtual environments.
Cell Phone Use While Driving: Risk Implications for Organizations (2014)

Cell phones and smartphones have become valuable tools for personal convenience and safety, as well as for conducting business and increasing productivity. In December 2013, the number of cell phone subscriber connections in the U.S. reached 335.6 million [4], representing a penetration level of more than 100% of the total U.S. population. In addition to personal convenience and safety, many people use their cell phones while driving, to leverage commute time. The latest U.S. National Highway Traffic Safety Administration (NHTSA) survey estimated that the percentage of vehicles whose drivers were using either handheld or hands-free phones was 9% at a typical daylight moment, and the percentage of drivers text-messaging or visibly using handheld devices increased significantly from 0.9% in 2010 to 1.3% in 2011 [16].
[Progressing myopia in children: does it need treatment or not?]. (2005)

The purpose of the case study was to evaluate the remote consequences of a complex of laser and repeated surgical sclerorestorative procedures made in progressing myopia and its complications. Three hundred and forty-six children, aged 8-10, with rapidly progressing uncomplicated myopia of 4.25 to 9.5 D were shared between 2 groups. Two hundred and forty patients of the experimental group were made sclerorestorative procedures and transscleral low-energy laser stimulation of the ciliary muscle by means of infrared laser MACDEL-09. No such treatment was applied to patients of the control group. When indicated, preventive laser coagulation of the retina was made in both groups. The dynamic 10-year follow-up over the status of refraction and eye bottom showed that the complex scheme of repeated sclerorestorative procedures and low-energy laser treatment combined with preventive peripheral laser coagulation of the retina cut the rate of progressing myopia and prevented peripheral vitreoretinal dystrophy and retinal detachment in children and teenagers with progressing myopia.

Design of a multi-band antenna (2019)

The aim of this final year project is to design one printed bow-tie dipole multiband antenna operating frequency range between 900MHz~2.7GHz under three conditions (air, above a conducting ground at height h, in a cavity-backed). The process of solving the challenge which we faced in antenna design is also a learning process. The antenna design need consider a lot of parameters like: substrate materials type used, feeding scheme and dimensions of the antenna, reflection coefficient and antenna gain, radiation patterns. The designed antenna is constructed and simulated by ANSYS High-Frequency Structural Simulator (HFSS) and simulation results under three different conditions also need to be discussed and analyzed. The most important aim of this final year project is to get better antenna performance by varying the antenna structural dimension or adjust the height between antennas to conducting ground.
Simulations of the Effects of Diagenesis on the Evolution of Sandstone Porosity (2004)

Abstract Automated image analysis and image processing techniques make possible the simulation of sandstone diagenesis and prediction of pore system modification. Diagenetic processes in real rocks are simulated using a combination of element X-ray maps and backscattered electron images. Processes can also be simulated for computer-generated sand packs by image analysis and image processing. Compaction is simulated by moving grain centers closer together; overgrowth-type cementation is simulated by dilation of free grain surfaces; mineral dissolution is simulated by selective removal of specific minerals identified by the combination of element X-ray maps and backscattered electron images. The original and modified images can be processed and analyzed to reveal all the parameters needed to predict permeability using a Kozeny-Carman type equation. The computer modeling and image analysis approach can also be used to determine the specific effects of various diagenetic processes on porosity. The results are encouragingly realistic by reference to the few available well-characterized empirical datasets.

Electric Heating of I-84 in Ladd Canyon, Oregon (2006)

When highway grades in mountainous areas and superelevation on curved sections are combined with adverse winter weather conditions, these sections of highway can become particularly hazardous for large truck traffic. This report covers the design and installation of a system of electric heating cables in a problem section of interstate highway in eastern Oregon. The area has winter weather conditions severe enough to cause treacherous traction conditions in spite of treatment with sand and magnesium chloride. The heating system covers a bridge deck that transitions to a steep uphill grade while making a superelevated turn and continues for 7,700 ft (2,347 m) up the incline. A section of the report discusses problems with the system and planned upgrades and changes.
Studies of Immunity to <i>Fasciola hepatica</i>: Acquired immunity in cattle, sheep and rabbits following natural infection and vaccine procedures (1967)

Investigations of acquired immunity to Fasciola hepatica in calves, sheep and rabbits are described. With injections of extracts of imma- ture parasites retarded growth of the challenge infection was observed between the 6th and 7th week. Following a previous experience of a natural infection or viable fluke implants, retardation and reduced take of the challenge infection were observed. Considerable individual variation was present and the level of significance between treatment and control groups was low.
