A hybrid transformer model for determination of partial discharge location in transformer winding (2007)

Partial discharges are well known as a source for insulation degradation in power transformers. A hybrid transformer model is introduced to simulate the transformer winding transient response. Transformer structural data is used to determine the hybrid model parameters. Calculations of the hybrid transient model parameters are based on the parameters of the lumped parameter equivalent transformer model and electromagnetic rules. Modern computation techniques and optimizations are employed beside this model for PD location using the multi conductor transmission line model and also to analyze its propagation aimed at achieving (i) more reliable simulation results (ii) less computational time (iii) accurate results for a wide range of frequency. The simulation results on a 66 kV, 25 MVA fully interleaved winding are presented. The measurement results on this winding are employed to validate this model
Activation of Ras by Grb2-SOS: Demonstrating an Assembly Role of SH3 Domains (2003)

The animation shows a schematic representation of the assembly role of SH3 domain-containing proteins using Grb2 as an example. Growth factor stimulation leads to the activation of receptor tyrosine kinases and to the phosphorylation of the receptor tail and the stimulation of phosphorylation of related adaptor proteins (not shown). The resultant phosphotyrosines form docking sites for the adaptor protein Grb2 (through its SH2 domain). The Grb2 SH3 domains bind proline-rich motifs in SOS, the guanine nucleotide exchange factor for Ras, recruiting SOS to the membrane and colocalizing it with Ras. The resultant stimulation of Ras activates a mitogen-activated protein kinase cascade, leading to cell growth and differentiation. The animation could be useful in demonstrating how different protein domains allow dynamic regulation of protein activity, protein assembly, and protein recruitment, allowing cells to respond to signals from their extracellular environment.

High resolution phase contrast electron microscopy:imaging of single atoms and “amorphous state” (1978)

Using very thin films of graphite crystals as support films, we demonstrated some bright-field CTEM images of single tungsten atoms and surface structures of the graphite films. Theoretical calculation on these objects using phase object approximation supported the validity of our interpretation of the images. We made a further investigation on the similar phase objects by utilizing a JEOL-UHP objective pole-piece (C s = 0.7mm) installed in a JEM-100B microscope. This lens gives an “interpretable resolution”, , of 2.6Å. Practically, however, the attainable resolution is restricted by chromatic aberration and illumination angle, barring operational faults. These parameters modify the ideal image transfer functions in the higher frequency region and thus become important for discussing the high resolution details. The resolution measured for the new lens from the optical diffractograms was around 3.2Å, which is slightly better than the value 3.8Å for our old lens (BLG-pole-piece, C s = 2.0mm).

Electronic Structure of Tetracyanonickelate(II) (2019)

Tetracyanonickelate(II) has been a poster child of ligand field theory for several decades. We have revisited the literature assignments of the absorption spectrum of [Ni(CN)4]2– and the calculated ordering of orbitals with metal d character. Using low-temperature single-crystal absorption spectroscopy and accurate ab initio and density functional quantum mechanical methods (NEVPT2-CASSCF, EOM-CCSD, TD-DFT), we find an ordering of the frontier d- and p-orbitals of xy < xz, yz < z2 < z < x2–y2 < x, y and assign the d-d bands in the absorption spectrum to 1A1g → 3B1g < 3Eg < 3A2g < 1B1g < 1Eg < 1A2g. While differing from all previous interpretations, our assignments accord with an MO model in which strong π-backbonding in the plane of the molecule stabilizes dxy more than out-of-plane bonding stabilizes dxz and dyz.
I-Module Technology: Evaluation and Evolution (2013)

This paper reports on the progress in development of i-module technology (interconnect-module) at imec. First we briefly reintroduce the concept, and elaborate its potential benefits. Then we report our latest results in investigating the route that is closest to industrial viability within this concept: based on industrial MWT cells and conventional soldering. Progress is discussed in terms of fabrication and performance of mini-modules, including extended reliability testing. This way we want to indicate its potential industrial relevance. After this, we propose a next step towards improving module manufacturing, by adapting the interconnect metallization: instead of soldering, as a typical cell-level process, it might make more sense to consider technologies more geared towards module-level processing. Here, we demonstrate how module-level screenprinting of a low-temperature curing Ag paste may interconnect several cells in a single process step. For this demonstration, we have used small IBC cells from imec’s high-efficiency baseline. Finally, an outlook indicates how imec envisages an evolution towards more and more module-level processing, culminating in an i2-module concept, where cell (backside) processing is carried out on module-level.

Whole-Genome Sequencing of Lactobacillus Species from Two Commercial Probiotic Products (2017)

Eight <i>Lactobacillus</i> strains, each intrinsically resistant to an antibiotic, were isolated from two commercial probiotic products. Whole-genome sequencing identified two efflux transporters, a multidrug and extrusion protein (MATE) efflux transporter, and LmrCD, which may contribute to their intrinsic antibiotic resistance and may therefore facilitate their survival in the intestinal microbiota following antibiotic therapy.
Students' success in solving mathematical problems depending on different representations (2022)

In order to solve mathematical problems, students often need to make the transition from one representation of mathematical concepts in those problem formulations to another representation. In this paper we explore the influence of the representations used in the problem formulation (problems with the same mathematical background with regards to solving easier or more complex equations and determining the unknown value of the proportion) on students' success in solving those problems. On a representative sample of 584 8th grade students, we tested whether there were differences in students' success in solving mathematical problems while using symbolic, graphic, or verbal representations in the formulations of problems belonging to different level of complexity. Results of this research indicate that there is significant impact of the representations of mathematical concepts used in problem formulation on students' success. Furthermore, the level of impact of using different representations in problem formulations depends on the level of the problem complexity when it comes to students' success in solving those problems.
Stability analysis of position and force control problems for robot arms (1990)

A stability analysis for robot manipulators under the influence of external forces is presented. Several control objectives are considered: rejecting the external force as a source of disturbance, complying to the external force as a generalized mass-spring-damper system, and actively controlling the external force when a dynamic model for the environment is available. An explanation of instability is given for the case in which the environment has flexibility and the gains are inappropriately chosen. When the environment is stiff in the force control subspace, robust stability can be achieved via the integral force feedback.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Conditional equivalence (2010)

A typical software module evolves through many versions over the course of its development. To maintain compatibility with module clients, it is crucial that a module’s behavior at its interface does not change in an undesirable manner across versions. The problem of introducing changes which break interface behavior remains one of the most daunting challenges in the maintenance of large software modules. Static equivalence checking of sequential programs is a useful mechanism to validate semantic equivalence across refactoring changes. However, most changes corresponding to bug fixes and feature additions change the behavior of programs; equivalence checking tools are of limited help in such cases. In this work, we propose the notion of conditional (partial) equivalence, a more practical notion of equivalence in which two versions of a program need only be semantically equivalent under a subset of all inputs. We provide a compositional method for checking conditional domain for synthesizing non-trivial conditions under which two programs are equivalent. Additionally, we propose a method called differential inlining to lazily construct summaries of behavioral differences along differential paths interprocedurally, for recursionfree programs. We discuss preliminary experience of a prototype implementation on a set of medium sized C benchmarks.

Inhibition of Swelling-Activated Cl−Currents by Functional Anti-ClC-3 Antibody in Native Bovine Non-Pigmented Ciliary Epithelial Cells (2005)

The results suggest that endogenous ClC-3 is involved in mediating I(Cl,swell) of native bovine NPE cells. The delayed stimulation of I(Cl,swell) by PDBu may reflect upregulation of swelling-activated Cl(-) channels of different subtypes, especially when the function of ClC-3 is blocked. This information will be useful in understanding the mechanisms controlling aqueous humor formation and thereby intraocular pressure.
A Family of 32 nm IA Processors (2010)

Westmere is the latest IA processor family for mobile, desktop and server market segments, implemented on Intel's second-generation high-k metal gate 32 nm process. Westmere not only increases core count, cache size, and frequency within the previous generation's power envelope, it also provides further improvements in power efficiency, feature set, and support for combo DDR3 and low voltage DDR3 despite using a thin gate technology.
A Novel Dual Three-Phase Permanent Magnet Synchronous Motor With Asymmetric Stator Winding (2016)

Although three-phase permanent magnet (PM) motors are dominant in industry, multi-phase PM synchronous motors present higher torque-to-weight ratios, better efficiency, and low torque ripple compared with three-phase conventional PM motors. These features make fault-tolerant multi-phase PM motors become attractive for safety-critical applications. In this paper, a novel PM multi-phase motor design with a dual three-phase asymmetric stator winding is proposed. The winding structure of the proposed motor is unconventional due to selected slot-pole combinations. Therefore, an asymmetric winding is needed. The detailed finite-element analysis of the proposed motor and a performance comparison between the conventional integer-slot (72-slot/12-pole motor) with symmetric winding and the unconventional fractional-slot (78-slot/12-pole motor) PM motors with asymmetric windings is performed to see the benefits of the proposed motor. It was shown that the novel unconventional multi-phase PM motor has excellent torque quality and slightly higher torque density levels.
Expression of myogenin during embryogenesis is controlled by Six/ sine oculis homeoproteins through a conserved MEF3 binding site (1998)

Myogenin, one of the MyoD family of proteins, is expressed early during somitogenesis and is required for myoblast fusion in vivo. Previous studies in transgenic mice have shown that a 184-bp myogenin promoter fragment is sufficient to correctly drive expression of a beta-galactosidase transgene during embryogenesis. We show here that mutation of one of the DNA motifs present in this region, the MEF3 motif, abolished correct expression of this beta-galactosidase transgene. We have found that the proteins that bind to the MEF3 site are homeoproteins of the Six/sine oculis family. Antibodies directed specifically against Six1 or Six4 proteins reveal that each of these proteins is present in the embryo when myogenin is activated and constitutes a muscle-specific MEF3-binding activity in adult muscle nuclear extracts. Both of these proteins accumulate in the nucleus of C2C12 myogenic cells, and transient transfection experiments confirm that Six1 and Six4 are able to transactivate a reporter gene containing MEF3 sites. Altogether these results establish Six homeoproteins as a family of transcription factors controlling muscle formation through activation of one of its key regulators, myogenin.

Design of a holographic tracking module for long-range retroreflector free-space systems (2016)

Weight reduction and low power consumption are key requirements in the next generation of unmanned aerial vehicles (UAVs). To communicate with an operator, a secured link between the UAV and a ground-based station is desirable. To realize these links, retroreflecting free-space optics is potentially attractive as it offers light weight and low complexity at the UAV. However, the base station requires a high-performance tracking module to enable a steady illumination of the UAV retroreflector. In this paper, we present the design and implementation of a tracking system, which consists of coarse tracking and holographic fine tracking modules working cooperatively. Using this system, experimental field trials were carried out by mounting a multiple-quantum-well-based modulated retroreflector on a commercial UAV. A 2 Mbps optical link was achieved with a bit error rate of ∼2×10<sup>-4</sup> at a link range of 300 m.
Nuclear compartmentalization of TERT mRNA and TUG1 lncRNA is driven by intron retention (2021)

The spatial partitioning of the transcriptome in the cell is an important form of gene-expression regulation. Here, we address how intron retention influences the spatio-temporal dynamics of transcripts from two clinically relevant genes: TERT (Telomerase Reverse Transcriptase) pre-mRNA and TUG1 (Taurine-Upregulated Gene 1) lncRNA. Single molecule RNA FISH reveals that nuclear TERT transcripts uniformly and robustly retain specific introns. Our data suggest that the splicing of TERT retained introns occurs during mitosis. In contrast, TUG1 has a bimodal distribution of fully spliced cytoplasmic and intron-retained nuclear transcripts. We further test the functionality of intron-retention events using RNA-targeting thiomorpholino antisense oligonucleotides to block intron excision. We show that intron retention is the driving force for the nuclear compartmentalization of these RNAs. For both RNAs, altering this splicing-driven subcellular distribution has significant effects on cell viability. Together, these findings show that stable retention of specific introns can orchestrate spatial compartmentalization of these RNAs within the cell. This process reveals that modulating RNA localization via targeted intron retention can be utilized for RNA-based therapies.
Drive system and readout characteristics of Micro-Reflector optical disc (2007)

This paper reviews the analyses and the experimental results of Micro-reflector optical disc system. In Micro-reflector optical disc, data are recorded on multiple virtual planes in a monolithic holographic medium. We have demonstrated the possibility of huge capacity from our analyses of readout characteristics of the Micro-reflector. In addition, we have developed the five-axis servo control system in order to achieve precise control of two counter-propagating light spots in recording media. Using this system, we succeeded in four-layer recording/readout.
QUAL: A microcomputer system for qualitative simulation (1990)

The field of qualitative simulation and reasoning is rapidly becoming a sought after means for modeling physical systems. However, much is yet to be explored within this field. The central feature of qualitative modeling is the use of qualitative variable descriptions and logic rules for manipulat ing variable values between systemic states. In this paper, the development and applica tion of a generic qualitative simulation environment named QUAL is provided. This environment assists the user in setting up a qualitative model, executing it, and forming a decision tree of the results. The use of qualitative reasoning in a microcom puter simulation context is presented and used to identify limitations of a purely qualitative modeling environment.
An Update on Natural Antileishmanial Treatment Options from Plants, Fungi and Algae (2021)

Efficient drugs for the treatment of leishmaniasis, which is classified as a neglected tropical disease, are sought for. This review covers potential drug candidates from natural plant, fungus and algae sources, which were described over the last six years. The identification of these natural antileishmanials often based on the knowledge of traditional medicines. Crucial insights into the activities of these natural remedies against Leishmania parasites and against infections caused by these parasites in laboratory animals or patients are provided and compared with selected former active examples published more than six years ago. In addition, immuno-modulatory natural antileishmanials and recent developments on combination therapies including natural products and approved antileishmanials are discussed. The described natural products revealed promising data warranting further efforts on the discovery and development of new antileishmanials based on patterns from nature.
Studies on PIVKA-X (1975)

The incorporation of 14C-glucosamine and 3H-leucine into PIVKA-X and factor X has been studied in Macaca mulatta by means of a monospecific precipitating antiserum. No difference in the incorporation into PIVKA-X and factor X was found. The half-lives of PIVKA-X and factor X were similar (about 30-35 h and 27-31 h respectively) indicating that the vitamin K-induced modifications did not alter the survival of protein. A Russell's-viper venom/cephalin test system for factor X was more sensitive to inhibition by PIVKA-X than was a tissue thromboplastin-based system.
On random walks of Pollard's rho method for the ECDLP on Koblitz curves (2011)

Pollard's rho method is the asymptotically fastest known attack for the elliptic curve discrete logarithm problem (ECDLP) except special cases. It works by giving a pseudo-random sequence defined by an iteration function and then detecting a collision in the sequence. We note that the number of iterations before obtaining a collision is significant for the running time of the rho method and depends on the choice of an iteration function. For many iteration functions suitable for the ECDLP on elliptic curves except Koblitz curves, the number of iterations before obtaining a collision had been investigated. In this paper, we propose a new iteration function on Koblitz curves which is an extension of the iteration function proposed by Gallant et al. and analyze the performance on our iteration function experimentally.
Image fusion for context enhancement and video surrealism (2004)

We present a class of image fusion techniques to automatically combine images of a scene captured under different illumination. Beyond providing digital tools for artists for creating surrealist images and videos, the methods can also be used for practical applications. For example, the non-realistic appearance can be used to enhance the context of nighttime traffic videos so that they are easier to understand. The context is automatically captured from a fixed camera and inserted from a day-time image (of the same scene). Our approach is based on a gradient domain technique that preserves important local perceptual cues while avoiding traditional problems such as aliasing, ghosting and haloing. We presents several results in generating surrealistic videos and in increasing the information density of low quality nighttime videos.
