Online Kernel Learning with a Near Optimal Sparsity Bound (2013)

In this work, we focus on Online Sparse Kernel Learning that aims to online learn a kernel classifier with a bounded number of support vectors. Although many online learning algorithms have been proposed to learn a sparse kernel classifier, most of them fail to bound the number of support vectors used by the final solution which is the average of the intermediate kernel classifiers generated byonlinealgorithms. Thekeyideaoftheproposed algorithm is to measure the difficulty in correctly classifying a training example by the derivative of a smooth loss function, and give a more chance to a difficult example to
Towards Successful Realization of the LDACS Cybersecurity Architecture: An Updated Datalink Security Threat- And Risk Analysis (2019)

Currently Communication Navigation and Surveillance (CNS) in civil aviation are undergoing huge changes in the framework of the European SESAR and the US NextGEN research initiatives. One goal is to develop the Future Communication Infrastructure (FCI) for civil aviation, consisting of AeroMACs for airport communications, SatCOM for remote domains, and LDACS for long-range wireless digital communications. The trend towards digitalization is supposed to solve the problems of capacity shortage, frequency saturation and automated data processing. Due to the digitalization process in communication itself and especially in critical infrastructure a strong request for cybersecurity support was raised. Therefore, a threat-and-risk analysis for LDACS was performed resulting in a first cybersecurity architecture specification draft. This paper goes one step further, presenting a suitable set of algorithms and protocols for security support for LDACS. The set is evaluated performance and security wise to match the cybersecurity architecture specification identified in earlier work.
Novel Therapies for Crohn's Disease: Focus on Immunomodulators and Antibiotics (2006)

A number of new treatment modalities are being investigated for Crohn's disease. Many of them are promising, and some of these agents may be considered in treatment-refractory patients in the future. However, some of the agents reviewed here are not available in the US. Future studies need to be double-blinded and placebo- or other treatment-controlled in a more homogeneous patient population.
Cryogenic thin-film electron emitters (1974)

Thin-film electron emitters are described, which operate below 200°K and below a limiting critical applied voltage (νc) in a stable temperature-independent regime. Current-voltage characteristics and normal electron energy distributions are presented. Fabrication and operation criteria are outlined. Comparison with temperature-dependent emitters is made, and possible conduction mechanisms discussed briefly.
Network architecture for critical communications requirements (2002)

The authors describe the architecture, algorithms, protocols, and possible uses of a high-speed, demand-assigned network incorporating distributed restoration. Network features include the use of an adaptive, distributed restoration and provisioning algorithm, distributed databases and fiber-associated signaling links which increase the survivability and robustness of the system. The benefit of such a network architecture to users requiring high-speed digital services are that connections (perhaps connecting video or sensor information to collection locations) can be established on-demand, in a manner that bypasses parts of the public switched network (PSN). The restoration aspect of the architecture improves the reliability and survivability of these services in an economic way.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Lasing from dot-in-rod nanocrystals in planar polymer microcavities (2018)

Colloidal nanocrystals attract considerable attention in the field of light emitting devices thanks to their high fluorescence quantum yield, low amplified spontaneous emission (ASE) threshold, and spectral tunability <i>via</i> electronic structure engineering and surface functionalization. Combining polymer microcavities with colloidal nanocrystals as gain material promises a solution-based fabrication route to plastic laser cavities as well as applications in the field of smart flexible large area light sources and sensors. Here we demonstrate lasing from polymer microcavities embedding solution processable dot-in-rod (DiR) CdSe/CdS nanocrystals. Two highly reflective polymer dielectric mirrors are prepared by spin-coating of alternated layers of polyacrylic acid and poly(<i>N</i>-vinyl carbazole), with their photonic band gap tailored to the emission of the DiRs. The DiRs are enclosed in the polymer microcavity by drop-cast deposition on one mirror, followed by pressing the mirrors onto each other. We obtain excellent overlap of the ASE band of the DiRs with the photonic band gap of the cavity and observe optically pumped lasing at 640 nm with a threshold of about 50 μJ cm<sup>-2</sup>.
Caspase-dependent and -independent lipotoxic cell-death pathways in fission yeast (2008)

Understanding the mechanisms underlying lipid-induced cell death has significant implications in both cell biology and human diseases. Previously, we showed that fission-yeast Schizosaccharomyces pombe cells deficient in triacylglycerol synthesis display apoptotic markers upon entry into stationary phase. Here, we characterize the sequential molecular events that take place at the onset of cell death in S. pombe, including a surge of diacylglycerol, post-mitotic arrest, alterations in mitochondrial activities and in intracellular redox balance, chromatin condensation, nuclear-envelope fragmentation, and eventually plasma-membrane permeabilization. Our results demonstrated active roles of mitochondria and reactive oxygen species in cell death, and identified novel cell-death regulators--including metacaspase Pca1, BH3-domain protein Rad9, and diacylglycerol-binding proteins Pck1 and Bzz1. Most importantly, we show that, under different conditions and stimuli, failure to maintain intracellular-lipid homeostasis can lead to cell death with different phenotypic manifestations, genetic criteria and cellular mechanisms, pointing to the existence of multiple lipotoxic pathways in this organism. Our study represents the first in-depth analysis of cell-death pathways in S. pombe.
A system for aiding creative concept formation (1994)

This paper describes a system named AA1 (Articulation Aid 1) which aids human users in the formation of new concepts in the domain of engineering and science. From the viewpoint of concept formation, one main process of creation is divergent thinking in which broad alternatives are searched, and another process is convergent thinking in which a unique solution is sought. From the viewpoint of human activities, creation also includes the aspect of collaboration among people and the aspect of individual reflection, although they are interrelated. AA1, the system presented in this paper, supports divergent thinking during individual reflection. Engineers and scientists usually scrawl many notes on paper while exploring new possible concepts in the divergent thinking process. A system is needed to reflect the fragments of concepts that are not articulated yet and thereby stimulate the formation of new concepts. AA1 builds a two-dimensional space from the words the user provides. Looking at this space and other precedent spaces, the user can form new concepts little by little. The main feature of AA1 different, from existing hypermedia systems and CSCW systems is the strategy for building the space presented to the user. The system is as nonprescriptive as possible, but it gives stimulation for the user to form concepts that he could not by using only pencil and paper. Experimentation has shown that the space which AA1 displays can effectively help the user to build new concepts. The most prominent effect is that empty regions in the space automatically configured by the system often lead to new concepts.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Phase II trials of methylglyoxal-bis (guanylhydrazone) (1982)

Broad phase II trial of methylglyoxal-bi (guanylhydrazone) (MGBG) is under way at the Memorial Sloan-Kettering Cancer Center. Studies in renal cell carcinoma, lymphomas, and non-small-cell lung cancer are completed, and substantial numbers of patients with esophageal and head and neck cancer have been treated. Small numbers of patients with other solid tumors have also been entered into the study. MGBG has significant antineoplastic activity against lymphomas, with 16/40 heavily pretreated patients (40%) having partial remissions (PR) lasting 1 to 8+ months. MGBG has also demonstrated more modest activity in non-small-cell lung cancer, esophageal, and head and neck carcinoma; it appears to have little or no therapeutic value in renal cell cancer. Toxicities have been manageable, and included mild nausea and vomiting, diarrhea, mucositis, and myelosuppression. The dose-limiting toxicity, seen most frequently in those patients with impaired renal function, was lethargy and fatigue. MGBG has demonstrated activity in lymphomas, lung, esophageal, and head and neck cancer. Further trials of this agent are indicated, both alone and in combination.
In Vitro Activities of the Everninomicin SCH 27899 and Other Newer Antimicrobial Agents against <i>Borrelia burgdorferi</i> (1999)

The in vitro activity of the everninomicin antibiotic SCH 27899 against 17 isolates of Borrelia spp. was investigated. MICs ranged from 0.06 to 0.5 microg/ml. Time-kill studies with the B31 strain of B. burgdorferi demonstrated >/=3-log10-unit killing after 72 h with concentrations representing four times the MIC. The in vitro activity of four other newer antimicrobial agents, meropenem, cefepime, quinupristin-dalfopristin, and linezolid, was also tested against the B31 strain. Meropenem was the most potent of the latter agents, with an MIC of 0.125 microg/ml.
Digital RFI suppression in DMT-based VDSL systems (1998)

Abstract—In this paper, we propose a method for suppressing radio frequency interference (RFI) in discrete multitone (DMT) based very high bit rate digital subscriber line (VDSL) systems. The method operates in the frequency domain of a DMT system. First, we derive a model of how an unknown narrow-band RF signal is mapped onto the DMT carriers. Then, by measuring the RFI on a few unused DMT carriers we are able to subtract RFI estimates from every modulated subcarrier. Simulation results show that this method, applied to an RFI signal with the same average power as the VDSL signal, suppresses the RFI with 40–50 dB, which reduces the average SNR loss from about 20 to less than 0.3 dB. Index Terms—Discrete multitone (DMT), radio frequency interference (RFI), subscriber loops, very high bit rate digital subscriber line (VDSL). I.
[Relations between the physico-chemical properties, the chemical reactivity and the local-anesthetic activity/part 33: studies on the interactions of local-anesthetically active cinchocaine homologues with phospholipids (author's transl)]. (1975)

The general part consists of a review on nerve stimulus mechanism as well as the nerve structure and the function of nerve membrane as the site of action of local anesthetics. Furthermore a possibility of interaction between local anesthetics and the membrane components especially phospholipids is discussed. These phospholipids show interesting properties with respect to ions as well as local-anesthetics, which allow us to suppose that they are important participants in nervous stimulus transmission. In the experimental part two methods are described. The first deals with the measurement of electrical resistance as function of time at cephalin and cholesterin impregnated filter membrane in solutions of cinchocain homologues. An increase in the resistance with the increase in concentration of test substances was observed. The same was the effect of increasing chain length in alkoxy group where after butoxy derivative, a deformation of membrane was observed. In the second method the drug binding capacity of cephalin dispersed in aqueous medium was measured. Here, too, the increase in the binding capacity with the increase in alkoxy chain was observed. The large difference in free binding energy between two subsequent homologues is explained as the effect of increase in van der Waals' forces and hydrophobic interactions on one hand, and a change in colloidal form of cephalin dispersion on the other hand.
Konversion von Lambwellenmoden in CFK-Platten (2012)

Kurzfassung. Lambwellen eignen sich zur integrierten Bauteiluberwachung (SHM Structural Health Monitoring) von Faserverbundbauteilen. Sie konnen mit Hilfe piezoelektrischer Flachenaktoren angeregt und empfangen werden. Unter bestimmten Bedingungen konvertieren symmetrische und antisymmetrische Wellenmoden ineinander. Um die Konversionsprodukte zur Detektion oder gar Ortung von Defekten nutzen zu konnen, mussen die Konversionsbedingungen aufgeklart werden. Der Beitrag konzentriert sich zunachst auf Untersuchungsergebnisse zur lokalen, d.h. von Fehlstellen verursachten Modenkonversion und zeigt, unter welchen Voraussetzungen mit nutzbaren Konversionsprodukten zu rechnen ist. Daruber hinaus wird das von den Autoren unlangst erkannte Phanomen der schleichenden Modenkonversion (CMC Continuous Mode Conversion) vorgestellt und der aktuelle Erkenntnisstand dargelegt.
DSM vs. NSM (2008)

Comparisons between the merits of row-wise storage (NSM) and columnar storage (DSM) are typically made with respect to the persistent storage layer of database systems. In this paper, however, we focus on the CPU efficiency tradeoffs of tuple representations inside the query execution engine, while tuples flow through a processing pipeline. We analyze the performance in the context of query engines using so-called "block-oriented" processing -- a recently popularized technique that can strongly improve the CPU efficiency. With this high efficiency, the performance trade-offs between NSM and DSM can have a decisive impact on the query execution performance, as we demonstrate using both microbenchmarks and TPC-H query 1. This means that NSM-based database systems can sometimes benefit from converting tuples into DSM on-the-fly, and vice versa.
Corrosion effects in thin‐film photovoltaic modules (2003)

Abstract Electrochemical corrosion effects can occur in thin‐film photovoltaic (PV) modules that are fabricated on tin‐oxide‐coated glass when operating at high voltages and at elevated temperatures in a humid climate. The current study shows that this corrosion is associated with a delamination of the tin oxide layer from the glass, which is caused by sodium accumulation near the interface between the tin oxide and the glass and by the ingression of moisture into the PV module from the edges. This corrosion in thin‐film PV modules can be significantly reduced by altering the growth conditions of the tin oxide or by using zinc oxide as a transparent conductive oxide electrode.

[Changes in postural control mechanism after a long-time tilt]. (2002)

In order to investigate the time-dependent dynamics of otolith organ-spinomotor function, we analyzed postural control biomechanically, in eight healthy adult volunteers, using a dynamic posturography (EquiTest System), before and after a four-hours lateral head and body tilt (90 degrees). After the tilt, a half of the subjects exhibited some changes. Their equilibrium scores decreased; i.e., the dependence on their vestibular inputs decreased, but in contrast, those on the visual and the somatosensory inputs increased. These changes were diminished by repeating the tests along the time course. The present findings confirmed [correction of comfirmed] the importance of vestibular gravity information for the maintenance of delicate postural stability.

Cancellation of nonlinearities in bandpass QAM systems (1990)

An orthogonalized input-output characterization of nonlinear bandpass quadrature amplitude modulation systems with memory is developed. The orthogonal expansion is used with a nonlinear canceller structure to counteract the effect of nonlinear distortion introduced by high-power amplifiers at the transmitter. It is shown through simulations that when the transmitted symbols are known at the canceller, relatively simple structures can eliminate the effect of the nonlinearity. Even when the transmitted symbols are not known at the canceller, the improvement in performance with the nonlinear canceller, with respect to a linear receiver, is significant.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Optical network configuration methods considering end-to-end latency in data centers (2015)

In recent years, data centers have been required to manage ever-increasing amounts of data resulting from the explosive growth of data-intensive Internet services. Data centers must provide high performance while minimizing energy consumption. To achieve these objectives, optical network technology can be implemented in data center networks. Optical networks in large-scale data centers must be configured to transmit large amounts of data with minimal latency. In this paper, we propose data center network configurations that are designed to reduce end-to-end latency. We configure two data center optical networks by splitting switches into groups and subgroups. Full mesh networks are used to connect groups and subgroups, and to implement connections within subgroups. Based on evaluations conducted using simulations, the proposed networks show high performance against Torus networks, and show low configuration costs against FatTree networks.
Demonstration of cell‐mediated immunity to human neoplasms of various histological types (1971)

Abstract Peripheral blood lymphocytes from a total of 373 tumor patients were tested by either a colony inhibition or a cytotoxicity test for cell‐mediated immunity against human neoplasms of various histological types. Lymphocytes from 51 of 59 patients studied (88%) either reduced colony numbers formed by plated autochthonous tumor cells or were cytotoxic to them, and lymphocytes from 78 of 87 patients tested (89%) had a similar effect on allogeneic tumor cells of the same histological type as those of the lymphocyte donors. Evidence indicating antigenic cross‐reactivity between tumors of the same histological type was obtained for the following seven groups of neoplasms: malignant melanomas, carcinomas of the colon, breast, testis, endometrium and ovary, and various sarcomas. Lymphocytes affecting tumor cells had no effect on normal cells from the same patient, or on cells from other types of neoplasms than the target cells under study. The degree of cell‐mediated immunity, as detectable with the techniques employed, was approximately the same in patients having active neoplastic disease as in patients who were clinically symptom‐free. Eleven of 12 patients who were tested after having been symptom‐free for more than 2 years had a lymphocyte‐mediated anti‐tumor immunity.

FSANZ, which sets standards within Australia and New Zealand, was also represented.
Composition of Indian Curry Leaf Oil (1999)

Abstract The essential oil of Indian curry leaf (Murraya koenigii Spreng.) collected from two different places in India has been investigated for its composition by GC and GC/MS. The oils from the two places were found to contain mostly monoterpenes and oxygenated monoterpenes. The main constituents of the oil identified are α-pinene (19.0–19.7%), sabinene (31.8–44.8%), β-pinene (4.2–4.7%), α-terpinene (1.3–4.3%), β-phellandrene (6.5–7.9%), γ-terpinene (3–9-7.1%) and terpinen-4-ol (5.2–9-9%).
