Effect of 1,4-naphthoquinone annelation on the conformational behavnniour of carbonyl- and methano-bridged cyclodecadiene derivatives (1991)

The Na2Cr2O7 oxidation of hexahydro-7,16-methanodinaphtho[2,3-a:2′,3′-f] cyclodecene derivative 2, produced two bis-(1,4-naphthoquinone)s, 7 and 9, and monoquinone compound 8. Benzonaphtho derivative 3 gave two 1,4-naphthoquinone derivatives, 10 and 11, on oxidation.Flexible compounds 7–11 showed temperature-dependent 1H NMR spectra due to equilibria among chair–boat, twin-chair, and boat–chair conformers, which were 1H NMR spectroscopically, characterized. A twin-chair conformer was detected in products 8, 9 and 10, but not in compounds 7 and 11. A broad absorption band due to an intramolecular C–T interaction in the twin-chair conformer was observed at λ∼ 400 nm in the electronic spectra of the monoquinones, 8 and 10, but not in the bis(quinone)9. Population of the twin-chair conformer increased with removal of the ester group on the bridgehead position. Reduction of the carbonyl group on the bridge also favoured the twin-chair conformation, indicating a repulsive interaction between the ester and the carbonyl group of the 1,4-naphthoquinone moiety. Upon irradiation with sunlight, compound 7 gave the [2 + 2]-photoadduct 15.
Highly power efficient, uncompromised performance cache design using dual-edged clock (2009)

Dynamic power dissipation is a major field where various researches have been held to reduce the energy consumption in present clocked systems. Here we discuss the various tiers of power management in design followed by a treatise on dynamic power dissipation in CMOS circuits and power efficient cache designs under research. We further propose a technique in reducing the clock frequency of circuits without compromising the performance. This is achieved by using a dual-edged clock for the operation, allowing the operating frequency to be halved, which immediately translates into a tremendous gain in power efficiency. The applications of this technique in processor caches are also studied. The designs proposed herein were implemented using Verilog HDL and the power requirements analyzed using Xilinx XPower 10.1. Experimental results and the conclusions drawn are included.
Multiple Myeloma Prognosis From PET Images: Deep Survival Losses and Contrastive Pretraining (2023)

Objective: Diagnosis and follow-up of multiple myeloma (MM) patients involve analyzing full body positron emission tomography (PET) images. Toward assisting the analysis, there has been an increased interest in machine learning methods linking PET radiomics with survival analysis. Despite deep learning’s success in other fields, its adaptation to survival faces several challenges. Our goal is to design a deep learning approach to predict the progression-free survival (PFS) of MM patients from PET lesion images. Methods: we study three aspects of such deep learning approach: 1) Loss Function: we review existing and propose new losses for survival analysis based on contrastive triplet learning; 2) Pretraining: we conceive two pretraining strategies to cope with the relatively small datasets, based on patch classification and triplet loss embedding; and 3) Architecture: we study the contribution of spatial and channel attention modules. Results: our approach is validated on data from two prospective clinical studies, improving the c-index over baseline methods, notably thanks to the channel attention module and the introduced pretraining methods. Conclusion and Significance: we propose for the first time an end-to-end deep learning approach, M2P2, to predict the PFS of MM patients from PET lesion images. We introduce two contrastive learning approaches, never used before for survival analysis.
The Vienna LTE simulators - Enabling reproducibility in wireless communications research (2011)

In this article, we introduce MATLAB-based link and system level simulation environments for UMTS Long-Term Evolution (LTE). The source codes of both simulators are available under an academic non-commercial use license, allowing researchers full access to standard-compliant simulation environments. Owing to the open source availability, the simulators enable reproducible research in wireless communications and comparison of novel algorithms. In this study, we explain how link and system level simulations are connected and show how the link level simulator serves as a reference to design the system level simulator. We compare the accuracy of the PHY modeling at system level by means of simulations performed both with bit-accurate link level simulations and PHY-model-based system level simulations. We highlight some of the currently most interesting research questions for LTE, and explain by some research examples how our simulators can be applied.
Circulations maritimes : l'Espagne et son empire (2011)

Les textes réunis dans cet ouvrage offrent une vision à la fois diverse et cohérente du fonctionnement des sociétés maritimes et marchandes au sein de la monarchie hispanique de l'époque moderne. La diversité est inhérente à l'hétérogénéité d'un empire sur lequel « le soleil ne se couchait jamais ». Pourtant, les modes de fonctionnement des multiples acteurs conviés par les divers auteurs sont non seulement relativement proches mais surtout étroitement dépendants les uns des autres. Surtout, leurs parcours rendent manifeste la première mondialisation réalisée au XVIe siècle dans le cadre de l'empire espagnol. C'est bien elle que tous les textes reflètent, expriment ou analysent, à leur manière et au-delà de la spécificité des études de cas proposées. Si cette première mondialisation renvoie aux inévitables processus de « métissages », des peuples autant que de leurs cultures ou de leurs religions, ses soubassements économiques et commerciaux restent essentiels à sa compréhension. Précisément, c'est l'étude des modalités de fonctionnement de cette économie-monde, pour reprendre l'expression braudélienne, qui constitue le cœur des réflexions développées dans cet ouvrage centrant la focale sur les acteurs de cette mondialisation économique de l'époque moderne. Au-delà de la diversité de situations concrètes qui renvoient à la prise en considération des enracinements factuels des divers exemples développés, les auteurs offrent une vision particulièrement homogène des pratiques marchandes et maritimes à partir des questionnements communs qu'ils mobilisent, à savoir une approche fondamentalement relationnelle centrée sur les acteurs, leurs stratégies et leurs réseaux.
The effect of residual impurity B or P on photovoltaic properties of amorphous silicon solar cells (1982)

The effect of residual impurity on the performance of a-Si:H solar cells has been studied in some detail. It is found that the electronic properties of the undoped layers are influenced by preparation processes; consequently an nip/sub. cell may be of ni(slightly B doped)p/sub. structure, a pin cell being pn/sup -/(slightly P doped)n. As compared to the pin/sub. cells, a higher open circuit voltage, which is virtually due to boron contamination of the i-layer, has been observed for the nip/sub. cells. Using special solar cell structures whose central regions were intentionally boron doped during preparation processes, the authors showed how the performance of a solar cell can be controlled by slightly boron doping its central region.
DAMAGE ANALYSIS OF RIGID PVC PIPE AND STEEL PIPE FOR COMMUNICATION (2020)

通信を支える地下管路では地震被害が一部発生しケーブルを傷つける可能性があるため，対策のための被害予測が重要となる．中でも旧仕様の鋼管，ビニル管において比較的被害が発生しやすいが，それぞれ被害の特徴が異なると考えられる．本稿では被害傾向を過去の地震から統計的に分析し，それぞれ様々な指標での傾向を把握した．結果として鋼管と硬質塩化ビニル管の被害率を比較すると地震動，亘長，地盤それぞれの指標において傾向に差があった．また，熊本地震を事例として被害箇所の特徴を確認すると，液状化や断層が見られた箇所では両管路ともに被害が発生していた．また鋼管のみに被害が集中している箇所においては管軸方向のひずみが，ビニル管のみに被害がある箇所では管軸直角方向の変状が確認され，統計的な傾向に反しない事例が確認された．
Design av Riskdatabas : En studie för effektivare hantering av risker (2013)

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks’ significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation. Furthermore, personal meetings were conducted within the framework of risk management.The study has resulted in development of relational models, one entity relationship model and one data model, which are essential for the database implementation. The modelling technique was based on an approach founded by Chen (1976). This modelling approach is still actively used in education and by developers within entity-relationship modelling and database design.The developed design supports the implementation of the data model in a risk repository, which eventually supports decision-making in risk management for businesses. A suggestion for further research has also emphasized the risk repository. The suggestion aims to increase the efficiency of the database of a computing system which enables cost estimates of potential risks that may occur.
Instrumentation and Developments (2005)

Mass spectrometry is one of the core components of modern proteomics. This central role is the direct result of continuous development and automation which mass spectrometry has experienced particularly over the last twenty years. The two ionization methods, ESI and MALDI together with two earlier ionization methods, FAB and 252Cf PD are described in some details. It has to be pointed out that on the instrumentation side there are a number of aspects, which are given a particular attention: • Ion analysis is one component, which has experienced the major development over the last 20 years. Such development has resulted in a number of new analyzers, which are playing a central role in today's proteomics. Among the emerging configurations described in this chapter are MALDI-TOF-TOF, linear ion trap-FT-ICR, and ion mobility-TOF. As well as these emerging configurations, an ample coverage of the well-established mass spectrometers such as the triple quadrupole, 3-D ion trap and quadrupole-TOF is also given. • On the detection side, the authors discuss the advantages and limitations of micro-channel plates (MCPs), which are still the favorite detectors for commercial mass spectrometers. The need to improve the performance of these detectors to meet emerging needs in proteomics is underlined. A detailed discussion of cryogenic detectors both superconducting tunnel junction and thermal and their possible use as an alternative to MCPs is also given. • The use of different MS data to search databases is another topic covered in this chapter. These data include MS-MS data generated by collision induced dissociation, peptide mass finger printing and post source decay. The capability of MALDI-TOF-TOF to generate high collision energy data and its influence on the accuracy of the search is also underlined. • The increasing use of multi-dimensional chromatography in conjunction with various MS configurations and its contribution to high throughput proteomic analysis is discussed. The advantages and limitations of this approach and its comparison with gel-based separation are also highlighted.
Nuclear-pumped lasing of 3He-Xe and 3He-Kr (1977)

Direct nuclear pumping of 3He-Xe and 3He-Kr has been achieved using the volumetric 3He(n,p)3H nuclear reaction. Lasing occurred at 2.027 μ and near 2.5 μ in Xe I and Kr I, respectively. The Xe transition has the lowest lasing flux threshold to date, 4×1015 n/cm2 sec. Scaling with both thermal flux and total pressure has been investigated.
Two new cave-dwelling Laemostenus (Antisphodrus) species from south-western Anatolia (Coleoptera, Carabidae) (2003)

Two new species of cave-dwelling species of Laemostenus are described from south-western Anatolia. One of them, L. (Antisphodrus) kestelensis Casale, Felix & Muilwijk, sp. n., was discovered by the Netherlands Biological Exploration to Turkey, nr. 7 in 1987. The only specimen known so far of the other species, L. (Antisphodrus) gasparoi Casale, sp. n., was collected in 1998. This latter specimen, with a description of its genitalia, was previously incorrectly attributed to L.
SARS-CoV-2 neutralizing antibody responses are more robust in patients with severe disease (2020)

We studied plasma antibody responses of 35 patients about 1 month after SARS-CoV-2 infection. Titers of antibodies binding to the viral nucleocapsid and spike proteins were significantly higher in patients with severe disease. Likewise, mean antibody neutralization titers against SARS-CoV-2 pseudovirus and live virus were higher in the sicker patients, by ∼5-fold and ∼7-fold, respectively. These findings have important implications for those pursuing plasma therapy, isolation of neutralizing monoclonal antibodies, and determinants of immunity.
Numerical simulation of SU-8 optical accelerometers (2006)

This contribution deals with the optimization of a new SU-8 optical accelerometer. Microaccelerometers became large-scale production devices the last 90's. Several working principles have been applied for acceleration sensing. However, most of them suffer from high cross-sensitivity to electromagnetic interferences (EMI) and they cannot be used under harsh/explosive atmospheres. Therefore, optical accelerometers can be used to avoid these drawbacks. We introduced a new integrated polymer optical accelerometer based on intensity modulation formed by a SU-8 polymer structure. The SU-8 polymer is used as structural material but also as optical waveguide. It consists of one mass adjoined to four beams, all of them made of SU-8. There are three aligned optical waveguides: one on the mass and two fixed to the substrate. Any applied acceleration will misalign the three waveguides; the losses show the acceleration level. The paper is focused on the numerical simulation of this device. It is a one-way sequentially coupled analysis. Firstly, a finite element method (FEM) simulation is done to calculate the mechanical sensitivity of the structure. In parallel, the beam profile at the waveguides is computed by using the non-uniform finite difference method (NU-FDM). Finally, the evolution of the light beam in the propagating axis of the waveguides is simulated using the beam propagation method (BPM) by introducing the results of the previous simulations as loads. The good agreement between the experimental results and the simulation demonstrates the feasibility of the sequential couple of the mechanical and optical fields by using the three different numerical methods
Construction of RSA cryptosystem over the algebraic field using ideal theory and investigation of its security (2000)

The RSA cryptosystem is extended to the algebraic field by using ideal theory. In this paper, we describe the generation algorithm of prime ideals, how to select a representative class using an ideal as modulus, and the algorithm to compute a representative element, for cyclotomic fields and quadratic fields. From here, an RSA cryptosystem can be constructed on cyclotomic fields and quadratic fields. To break completely the proposed cryptosystem, when the public key is a product of inert prime numbers, is the same as for the conventional RSA cryptosystem and its security is better against the Håstad attacks. © 2000 Scripta Technica, Electron Comm Jpn Pt 3, 83(8): 19–29, 2000
Theoretical Analysis on the Measurement Errors of Local 2D DIC: Part I Temporal and Spatial Uncertainty Quantification of Displacement Measurements (2015)

Abstract This paper presents a theoretical uncertainty quantification of displacement measurements by subset‐based 2D‐digital image correlation. A generalised solution to estimate the random error of displacement measurement is presented. The obtained solution suggests that the random error of displacement measurements is determined by the image noise, the summation of the intensity gradient in a subset, the subpixel part of displacement, and the interpolation scheme. The proposed method is validated with virtual digital image correlation tests.
Personalized visual aesthetics (2014)

How is visual information linked to aesthetic experience, and what factors determine whether an individual finds a particular visual experience pleasing? We have previously shown that individuals’ aesthetic responses are not determined by objective image features but are instead a function of internal, subjective factors that are shaped by a viewers’ personal experience. Yet for many classes of stimuli, culturally shared semantic associations give rise to similar aesthetic taste across people. In this paper, we investigated factors that govern whether a set of observers will agree in which images are preferred, or will instead exhibit more “personalized” aesthetic preferences. In a series of experiments, observers were asked to make aesthetic judgments for different categories of visual stimuli that are commonly evaluated in an aesthetic manner (faces, natural landscapes, architecture or artwork). By measuring agreement across observers, this method was able to reveal instances of highly individualistic preferences. We found that observers showed high agreement on their preferences for images of faces and landscapes, but much lower agreement for images of artwork and architecture. In addition, we found higher agreement for heterosexual males making judgments of beautiful female faces than of beautiful male faces. These results suggest that preferences for stimulus categories that carry evolutionary significance (landscapes and faces) come to rely on similar information across individuals, whereas preferences for artifacts of human culture such as architecture and artwork, which have fewer basic-level category distinctions and reduced behavioral relevance, rely on a more personalized set of attributes.
AC characteristics of Cr/p/sup +/a-Si:H/V analog switching devices (2000)

Experimental results on the ac characteristics of electro-formed Cr/p/sup +/ hydrogenated amorphous silicon (a-Si:H)/V thin film memory devices are presented. The impedance spectrum of the memory switching device has been measured over a wide frequency range from 1 Hz-32 MHz while keeping the ac voltage amplitude below 0.02 V. Simulation of the measured impedance spectrum using an equivalent circuit indicates that the capacitance associated with a conducting filament tends to increase as the memory resistance decreases. This is explained on the basis of an activated tunnelling mechanism. Charge transport is dominated by electron tunnelling via metallic particles in the filament, and hence small changes in interparticle spacing influences the tunnelling process considerately, leading to changes in both memory resistance and effective dielectric constant.
Distortion measurement of optical system using phase diffractive beam splitter (2019)

Traditional methods for distortion measurement of large-aperture optical systems are time-consuming and ineffective because they require each field of view to be individually measured using a high-precision rotating platform. In this study, a new method that uses a phase diffractive beam splitter (DBS) is proposed to measure the distortion of optical systems, which has great potential application for the large-aperture optical system. The proposed method has a very high degree of accuracy and is extremely economical. A high-precision calibration method is proposed to measure the angular distribution of the DBS. The uncertainty analysis of the factors involved in the measurement process has been performed to highlight the low level of errors in the measurement methodology. Results show that high-precision measurements of the focal length and distortion were successfully achieved with high efficiency. The proposed method can be used for large-aperture wide-angle optical systems such as those used for aerial mapping applications.
Electrical Properties of Heated Dielectrics. (1982)

Abstract : A method has been described which allows one to analyze complicated currents emanating from warmed dielectrics. This technique is easily applied for temperature waves of certain amplitude and frequency limits and permits an accurate assessment of dielectric materials being examined for specific applications, such as infrared detectors or vidicon targets, where it is necessary to know the current magnitude and relaxation properties as a function of temperature and temperature changes. The low-frequency temperature wave method is a direct dynamic measurement of the pyroelectric coefficient. This method eliminates the nedd for measurements of specific heats, dielectric constants, and radiation absorption coefficients as well as identifying the effects due to irreversible currents which occur when samples are heated at a constant rate.
Improved Intelligent Image Segmentation Algorithm for Mechanical Sensors in Industrial IoT: A Joint Learning Approach (2021)

The industrial Internet of Things (IoT) can monitor production in real-time by collecting the status of parts on the production line with cameras. It is easy to have bright and dark areas in the same image because of the smooth surfaces of mechanical parts and the unstable light source, which affects semantic segmentation’s performance. This paper proposes a joint learning method to eliminate the influence of illumination on semantic segmentation. Semantic image segmentation and image decomposition are jointly trained in the same model, and the reflectance image is used to guide the semantic segmentation task without the illumination component. Moreover, this paper adopts an enhanced convolution kernel to improve the pixel accuracy and BN fusion to enhance the inference speed, optimizing the model to meet real-time detection needs. In the experiments, a dataset of real gear parts was collected from industrial IoT cameras. The experimental results show that the proposed joint learning approach outperforms the state-of-the-art methods in the task of edge mechanical part detection, with about 4% pixel accuracy improvement.
Adducin Regulates Sarcomere Disassembly During Cardiomyocyte Mitosis (2020)

Abstract Recent interest in understanding cardiomyocyte cell-cycle has been driven by potential therapeutic applications in cardiomyopathy. However, despite recent advances, cardiomyocyte mitosis remains a poorly understood process. For example, it is unclear how sarcomeres are disassembled during mitosis to allow abscission of daughter cardiomyocytes. Here we identify adducin as a regulator of sarcomere disassembly during mammalian cardiomyocyte mitosis. α/γ-adducins are selectively expressed in neonatal mitotic cardiomyocytes, and their levels decline precipitously thereafter. Cardiomyocyte-specific overexpression of various splice isoforms and phosphoforms of α-adducin in-vitro and in-vivo identified Thr445/Thr480 phosphorylation of a short isoform of α adducin as a potent inducer of neonatal cardiomyocyte sarcomere disassembly. Concomitant overexpression of this α-adducin variant along with γ-adducin resulted in stabilization of the adducin complex and persistent sarcomere disassembly in adult mice, which is mediated by interaction with α-actinin. These results highlight an important mechanism for coordination of cytoskeletal morphological changes during cardiomyocyte mitosis.
