Aufstiegskarrieren in der Schweiz (2010)

Jede historische Epoche bringt ihre ganz eigenen und typischen Biographiemuster hervor. Diese entstehen in Abhängigkeit von demographischen und ökonomischen Bedingungen, werden geformt von den institutionellen Strukturen, in welchen sich die Individuen bewegen und den Entscheidungen, die die Akteure an den Scheidepunkten ihrer Biographie treffen. Gemäß Martin Kohli hat die Biographie nie eine fundamentalere Rolle gespielt als in den modernen Gesellschaften (Kohli, 1985). Mit dem demographischen Wandel, der Standardisierung der Familienzyklen und der Rationalisierung von Arbeit verwandelt die Moderne den Lebenslauf in eine eigene soziale Institution (Kohli, 1985). Deshalb müssen wir Modernisierung immer auch als ein Prozess der Institutionalisierung des Lebenslaufs verstehen.
357 SKIN TEST REACTIVITY OF SHRIMP-ALLERGIC SUBJECTS TO INHALANT AND OTHER FOOD ALLERGENS (2005)

<h3>Rationale</h3> Shrimp is a major seafood consumed in the U.S. and also an important seafood allergen. The major shrimp allergen is the muscle protein tropomyosin, which is present in other inhaled and ingested allergens. Thus, it was of interest to determine potential sensitivity of shrimp-allergic subjects to these other allergens. <h3>Methods</h3> Shrimp-allergic subjects were recruited by advertisement. 58 subjects (25 male, 33 female) ages 18-63, with definitive histories of shrimp allergy, as determined by questionnaire, were selected. Subjects were skin prick tested (ST) with aeroallergen and shellfish food extracts from Hollister-Stier; positive ST was determined by wheal with flare. IgE antibody responses to shrimp were measured by CAP-RAST. <h3>Results</h3> 37/58 (64%) subjects were ST positive to at least 1 of the 2 shrimp extracts tested, 41 (71%) were positive to either crab, lobster, crawfish, or oyster, 51 (88%) to either cockroach or dust mite, 19 (33%) to tree pollens, and 14 (24%) to grass pollens. Of the 37 subjects ST positive for shrimp, 35 (96%) were positive to crab, lobster, or crawfish. 36 (97%) reacted to either cockroach or dust mite. Of the 58 original subjects, 28 (48%) had undetectable IgE to shrimp (class 0) on CAP-RAST analysis. Of the 37 shrimp ST positive subjects, only 10 (27%) had no detectable IgE to shrimp. <h3>Conclusions</h3> Shrimp-allergic subjects showed significant reactivity to other shellfish, the greatest was to lobster (89%), the least to oysters (43%). Significant reactivity was observed to cockroach and dust mite extracts which is probably due in part to cross reactivity of invertebrate tropomyosin allergens. Better understanding of food and aeroallergen cross-reactivity should help improve diagnosis and therapy of food allergy.
Trypanosoma cruzi-induced suppression of human peripheral blood lymphocytes activated via the alternative (CD2) pathway (1990)

Coculture of blood forms of Trypanosoma cruzi with human peripheral blood mononuclear cells stimulated with anti-CD2(2) and anti-CD2(3) monoclonal antibodies, i.e., via an antigen-independent pathway of T-lymphocyte activation, resulted in marked immunosuppression compared with that in parallel cultures in which parasites were absent. This effect was evidenced by a decreased lymphoproliferative capacity, a significant reduction in the proportion of cells expressing interleukin-2 receptors, and a significant diminution in the cell surface density of this receptor.
Weight cycling in a very low‐calorie diet programme has no effect on weight loss velocity, blood pressure and serum lipid profile (2006)

The present study refutes the hypothesis that repeated dieting makes further dieting efforts more difficult.

Genetic polymorphisms of the cancer related gene andHelicobacter pylori infection in Japanese gastric cancer patients: An age and gender matched case-control study (1996)

BACKGROUND Gastric cancer is a multistage process, each caused by numerous factors. The objective of this study was to elucidate the risk factors for gastric cancer by using molecular epidemiologic techniques and serum markers. METHODS Serum pepsinogen I levels, pepsinogen I/pepsinogen II (I/II) ratios, serum IgG antibody against Helicobacter pylori (H. pylori), and genetic polymorphisms of cytochrome p450 2E1 (CYP2E1), glutathione-S-transferase M1 (GSTM1), and L-myc protooncogenes were analyzed in 82 persons with gastric cancer and in 151 age- and sex-matched controls, who were selected from 208 gastric cancer patients and 375 noncancer patients, respectively. Statistical analysis was performed to elucidate which risk factors for gastric cancer were contributing the most to gastric carcinogenicity. RESULTS Serum pepsinogen I level (odds ratio [OR] = 1.81; 95% confidence interval [CI], 1.04–3.16) and pepsinogen I/II ratios (OR = 3.09; 95% CI, 1.74–5.49) were significantly associated with gastric cancer risk in a case–control study. Seropositivity of serum IgG antibody against H. pylori (OR = 1.25; 95% CI, 0.84–1.85) and specific genotypes of a L-myc genetic polymorphism (OR = 1.33; 95% CI, 0.59–2.99) were more commonly observed in gastric cancer cases, but this was not statistically significant. Specific genotypes of the CYP2E1 RsaI polymorphism and GSTM1 gene deletion were not associated with gastric cancer. CONCLUSIONS Atrophic mucosal change, indicated by serum pepsinogen levels, is possible a risk factor for gastric cancer. H. pylori infection and genetic polymorphisms of CYP2E1, L-myc, and GSTM1 genetic polymorphisms were not risk factors in this study. Cancer 1996;77:1654-61.
Simulation of the head-related transfer functions using cloud computing (2013)

Due to the complexity of measurements for obtaining individual head-related transfer functions (HRTFs), numerical simulations offer an attractive alternative for generating large HRTF data bases. In this study, HRTFs are simulated using a fast multipole boundary element method (BEM). The BEM is well suited for the HRTF simulations. Namely, only the surface of the model geometry is discretized which simplifies the pre-processing compared to other full-wave simulation methods (such as finite element and finite difference methods). The BEM is formulated in frequency domain and the model is solved separately for each frequency. Since a large number of frequencies is needed in wide-band HRTF simulations, the BEM simulation greatly benefits from distributed (or parallel) computing. That is, a single computing unit takes care of a single frequency. In this study, a distributed BEM using cloud computing is introduced. Simulations are computed in a public cloud (Amazon EC2) using a realistic head and torso geometry (3D laser scanned geometry of Bruel & Kjaer HATS 4128 mannequin). The frequency range of the simulations is from 20 to 20000 Hz. The feasibility of cloud computing for simulating HRTFs is examined and first analysis results for the simulated HRTFs are shown.
Neuronal intracellular pH directly mediates nitric oxide-induced programmed cell death (1999)

Neuronal injury is intricately linked to the activation of three distinct neuronal endonucleases. Since these endonucleases are exquisitely pH dependent, we investigated in primary rat hippocampal neurons the role of intracellular pH (pH(i)) regulation during nitric oxide (NO)-induced toxicity. Neuronal injury was assessed by both a 0.4% Trypan blue dye exclusion survival assay and programmed cell death (PCD) with terminal deoxynucleotidyl transferase nick-end labeling (TUNEL) 24 h following treatment with the NO generators sodium nitroprusside (300 microM), 3-morpholinosydnonimine (300 microM), or 6-(2-hyrdroxy-1-methyl-2-nitrosohydrazino)-N-methyl-1-hex anamine (300 microM). The pH(i) was measured using the fluorescent probe BCECF. NO exposure yielded a rapid intracellular acidification during the initial 30 min from pH(i) 7.36 +/- 0.01 to approximately 7.00 (p <.0001). Within 45 min, a biphasic alkaline response was evident, with pH(i) reaching 7.40 +/- 0.02, that was persistent for a 6-h period. To mimic the effect of NO-induced acidification, neurons were acid-loaded with ammonium ions to yield a pH(i) of 7.09 +/- 0.02 for 30 min. Similar to NO toxicity, neuronal survival decreased to 45 +/- 2% (24 h) and DNA fragmentation increased to 58 +/- 8% (24 h) (p <.0001). Although neuronal caspases did not play a dominant role, neuronal injury and the induction of PCD during intracellular acidification were dependent upon enhanced endonuclease activity. Furthermore, maintenance of an alkaline pH(i) of 7.60 +/- 0.02 during the initial 30 min of NO exposure prevented neuronal injury, suggesting the necessity for the rapid but transient induction of intracellular acidification during NO toxicity. Through the identification of the critical role of both NO-induced intracellular acidification and the induction of the neuronal endonuclease activity, our work suggests a potential regulatory trigger for the prevention of neuronal degeneration.
Excitation of Microwave Vortices by Ferrite Disks: the Near-Field and Far-Field Application Problems (2006)

Abstract- A small FMR ferrite disk strongly perturbs the cavity field. Graphical representation of the Poynting vector shows that due to the vortex structure the absorption cross-section of a ferrite particle can be much bigger than its geometrical cross-section. Spectral properties of magnetic oscillations in a ferrite disk show unique vortex structures for MS-wave functions. Index Terms- microwave vortices, ferromagnetic resonance, MS-wave oscillations
Analysis of Proportional Fair Scheduling Under Bursty On-Off Traffic (2017)

Proportional fair scheduling (PFS) has been adopted as a standard solution for fair resource allocation in modern wireless cellular networks. With the emergence of heterogeneous networks with widely varying user loads, it is of great importance to characterize the performance of PFS under bursty traffic, which is the case in most wireless streaming and data transfer services. In this letter, we provide the first analytical solution to the performance of PFS under bursty on-off traffic load. We use the Gaussian approximation model to derive a closed-form expression of the achievable user data rates. In order to further improve the accuracy of our baseline analytical solution for multi-cell networks, we design a hybrid approximation by employing multi-interference analysis. The simulation results verify that our model guarantees extremely low data rate estimation error, which is further insensitive to changes in session duration, traffic load and user density.
Battery-aware localization in wireless networks (2009)

An important mechanism to conserve energy and extend the battery life of low-power wireless networks is to increase the sleep-cycle of the nodes. However, increasing sleep-cycles can have unintended consequences on the application performance. Therefore, it is important to understand the impact of various sleep-cycle parameters on the performance of any given application. In this paper, we analyze the relationship between the sleep-cycle period and the accuracy of the localization application. We show that the sleep-cycle period has an exponential relationship with many of the parameters that impact localization accuracy. In general, such relationships lend themselves especially well to energy efficient system-level design of location dependent applications. Finally, to demonstrate the validity of our analysis, using an IEEE 802.11 based localization system, we present a set of experimental results that show the relationships between the sleep-cycle and the measurements accuracies in the localization systems.
THREE POSSIBLE ORIGINS FOR THE GAS LAYER ON GJ 1214b (2010)

We present an analysis of the bulk composition of the MEarth transiting super Earth exoplanet GJ 1214b using planet interior structure models. We consider three possible origins for the gas layer on GJ 1214b: direct accretion of gas from the protoplanetary nebula, sublimation of ices, and outgassing from rocky material. Armed only with measurements of the planet mass (M_p=6.55+/-0.98 M_{earth}), radius (R_p=2.678+/-0.13 R_{earth}), and stellar irradiation level, our main conclusion is that we cannot infer a unique composition. A diverse range of planet interiors fits the measured planet properties. Nonetheless, GJ 1214b's relatively low average density (rho_p=1870+/-400 kg m^{-3}) means that it almost certainly has a significant gas component. Our second major conclusion is that under most conditions we consider GJ 1214b would not have liquid water. Even if the outer envelope is predominantly sublimated water ice, the envelope will likely consist of a super-fluid layer sandwiched between vapor above and plasma (electrically conductive fluid) below at greater depths. In our models, a low intrinsic planet luminosity (<~2TW) is needed for a water envelope on GJ 1214b to pass through the liquid phase.
Biomedical Exploitation of Chitin and Chitosan via Mechano-Chemical Disassembly, Electrospinning, Dissolution in Imidazolium Ionic Liquids, and Supercritical Drying (2011)

Recently developed technology permits to optimize simultaneously surface area, porosity, density, rigidity and surface morphology of chitin-derived materials of biomedical interest. Safe and ecofriendly disassembly of chitin has superseded the dangerous acid hydrolysis and provides higher yields and scaling-up possibilities: the chitosan nanofibrils are finding applications in reinforced bone scaffolds and composite dressings for dermal wounds. Electrospun chitosan nanofibers, in the form of biocompatible thin mats and non-wovens, are being actively studied: composites of gelatin + chitosan + polyurethane have been proposed for cardiac valves and for nerve conduits; fibers are also manufactured from electrospun particles that self-assemble during subsequent freeze-drying. Ionic liquids (salts of alkylated imidazolium) are suitable as non-aqueous solvents that permit desirable reactions to occur for drug delivery purposes. Gel drying with supercritical CO(2) leads to structures most similar to the extracellular matrix, even when the chitosan is crosslinked, or in combination with metal oxides of interest in orthopedics.
Fusion mass-splicing for optical fibres by discharge heating (1981)

A mass-splicing technique for tape-unit silica fibres based on discharge fusion is demonstrated. Five pairs of fibres are simultaneously fused and spliced together by the heat from the electric discharge between two pairs of electrodes. The average splice loss for 50 μm-core graded-index fibres is 0.22 dB.

Fuzzy Spatial Relationships and Mobile Agent Technology in Geospatial Information Systems (2002)

This chapter discusses an integrated work in the definition and implementation of sets of fuzzy spatial relationships concerning topology and direction. We present our basic approach to defining these relationships as an extension to previous work in temporal relations. We also discuss several extensions to this approach that include refinements and alternate definitions. Two implementations are also described, one in a C++, Oracle database environment and another utilizing the expert system shell Fuzzy Clips. Finally we discuss the integration of this querying approach in an agent-based framework. Agent technology has become a leading implementation paradigm for distributed and complex systems, and has recently garnered much interest from researchers in the area of spatial databases. Agents offer many advantages with respect to intelligence abilities and mobility that can provide solutions for issues related to uncertainty in spatial data, such as those of spatial relationships.
Dynamic ATM satellite networking (1998)

ATM offers two major benefits to telecom operators. The first is that a single network can carry many different traffic types, with various grades of service, multiplexed together. The second is that end-to-end managed services over a managed network can be provided using a combination of in-channel and overlay techniques. Dynamic ATM networking as opposed to static, implies the use and management of soft and switched virtual paths and circuits as opposed to permanent virtual paths and circuits. This paper describes work done at BT Laboratories on ATM signalling and SVCs over satellite and progress made on network management in the satellite environment. (5 pages)
Tropomyosin Inhibits the Glutaraldehyde-Induced Cross-Link between the Central 48-kDa Fragment of Myosin Head and Segment 48-67 in Actin Subdomain 2 (1994)

The glutaraldehyde-induced cross-linking of the F-actin-myosin head (S1) complex, previously described [Bertrand et al. (1988) Biochemistry 27, 5728-5736], was investigated in the presence of tropomyosin (Tm) alone or associated with troponin (Tn), at a Tm-Tn/actin/S1 molar ratio of 1:7:3. Among the two acto-S1 cross-linked products with apparent masses of 165 and 200 kDa generated in the absence of the regulatory proteins, only the 165-kDa adduct was formed in the presence of Tm. An identical result was obtained with and without Tn regardless of the presence of Ca2+ and/or Mg(2+)-ADP. The abolition of the 200-kDa cross-linked acto-S1 species was independent of the S1/actin ratio since even a 3-fold excess of S1 over actin, sufficient for fully turning on the thin filament, could not restore the 200-kDa covalent complex. In addition, the acto-S1 contacts cross-linked in either the 165- or 200-kDa product were not involved in the Ca(2+)-linked regulation of the acto-S1 ATPase activity, as the enzymatic activities of both types of complexes were regulated to the same extent by Ca2+/EGTA, in the presence of the regulatory proteins. Cross-linking experiments performed with [14C]glutaraldehyde showed that both covalent complexes were composed of 1 mol of actin bound to 1 mol of S1 heavy chain. The use of proteolytic actin or S1 derivatives together with the direct proteolysis of the acto-S1 covalent adducts revealed that Tm abolished the cross-link between the central 48-kDa fragment of the S1 heavy chain and Lys50 of actin subdomain 2 that is responsible for the formation of the 200-kDa entity, while it did not affect the cross-link between the S1 heavy chain segment of residues 636-642 and Arg28 of actin that generates the 165-kDa derivative. These results provide experimental clues for the interaction of S1 with actin subdomain 2 and show that this contact is implicated in the weak acto-S1 binding state. Furthermore they demonstrate the ability of Tm to affect the structure of actin subdomain 2 even in the presence of S1 bound in the rigor state.
Fault Isolation and TEM Study in State-of-Art Thin-Film Transistors (2015)

Abstract In this work, we discussed the fault isolation method for the Thin-Film Transistor (TFT). Many defects in the TFT can be directly observed by optical microscope; however, some defects are not visible in either optical microscope or SEM making the fault isolation effort very challenging. We demonstrated that OBIRCH can be used to find defect locations in TFT failures for leakage and shorts. The TFT is so fragile that the laser power and biasing voltage have to be very carefully controlled to avoid damaging the TFT. After identifying the defect location by OBIRCH hot spot detection, the defect was successfully captured with TEM analysis.
A Kernel Based Rejection Method For Supervised Classification (2007)

In this paper we are interested in classification problems with a performance constraint on error probability. In such problems if the constraint cannot be satisfied, then a rejection option is introduced. For binary labelled classification, a number of SVM based methods with rejection option have been proposed over the past few years. All of these methods use two thresholds on the SVM output. However, in previous works, we have shown on synthetic data that using thresholds on the output of the optimal SVM may lead to poor results for classification tasks with performance constraint. In this paper a new method for supervised classification with rejection option is proposed. It consists in two different classifiers jointly optimized to minimize the rejection probability subject to a given constraint on error rate. This method uses a new kernel based linear learning machine that we have recently presented. This learning machine is characterized by its simplicity and high training speed which makes the simultaneous optimization of the two classifiers computationally reasonable. The proposed classification method with rejection option is compared to a SVM based rejection method proposed in recent literature. Experiments show the superiority of the proposed method.
