Design for Manufacturing and Design Process Technology Co-Optimization (2020)

The ecosystem has historically featured so-called integrated device manufacturers spanning both integrated circuit (IC) design and manufacturing functions, as well as semiconductor foundries that produce chips for fabless design companies. The unsung hero of the arduous challenge to keep IC performance on track has been and continues to be a heterogeneous set of computationally intensive computer-aided design methodologies collectively known as design technology co-optimization or design tor manufacturing. Fundamental to the economics of semiconductor manufacturing and its relationship to electronic design is the concept of metal–oxide–semiconductor field-effect transistor device scaling, sometimes referred to as Dennard scaling. The goal of the fab process, of course, is to manufacture a given integrated circuit chip with as high a yield as possible, and to do so immediately upon introduction into manufacturing. Dose can serve as a proxy for a variety of different manufacturing process excursions, such as postexposure bake time and temperature.
Pushing the Limits of Clingo’s Incremental Grounding and Solving Capabilities in Practical Applications (2023)

Incremental techniques aim at making it possible to improve the performance of the grounding and solving processes by reusing the results of previous executions. Clingo supports both incremental grounding and incremental solving computations. In order to leverage incremental computations in clingo, the incremental fragments of ASP programs must satisfy certain safety-related conditions. In a number of problem domains and reasoning tasks, these conditions can be satisfied in a fairly straightforward way. However, we have observed that in certain practical applications, satisfying the conditions becomes more challenging, to the point that it is sometimes unclear how or even if it is possible to leverage incremental computations. In this paper, we report our findings, and ultimate success, with the use of incremental grounding and solving techniques in one of these challenging cases. We describe the domain, which is linked to a large practical application, discuss the challenges we faced in attempting to leverage incremental computations, and then describe the techniques that we developed, in particular at the level of methods for encoding the domain knowledge and of algorithms supporting the intended interleaving of grounding and solving. We believe that our findings may provide valuable information to practitioners facing similar challenges and ultimately increase the adoption of clingo’s incremental capabilities for complex practical applications.
Mechanical characteristics and mechanism of the triboluminescence of fluorescent molecular crystals (1980)

The mechanical characteristics of triboluminescence (TL) from coumarin, acenaphthene, resorcinol, phenanthrene, and m-aminophenol crystals are studied. The TL spectra of these crystals resemble their fluorescence spectra. The TL appears concurrently with the sudden force decreases in the fracture regions of the force vs compression curves of the crystals. The decay time of TL from the motion of a single crack is of the order of a microsecond. The dependence of the TL intensity on time, impact velocity, the applied stress, and the crystal dimensions is discussed quantitatively using a phenomenological theory based on the movement and interaction of cracks in the crystals. No systematic correlation of the normalized TL intensity with the photoluminescence efficiency, charge produced during crystal fracture, or the experimental fracture stress is found. No considerable differences are found between the TL intensities of crystals grown in argon and in nitrogen atmospheres when they are crushed inside argon-stripped liquid or in air. Triboluminescence is an intrinsic property of the crystals and is discussed in terms of the piezoelectrification produced during the movement of cracks in the crystals.
Throughput Analysis and User Barring Design for Uplink NOMA-Enabled Random Access (2020)

Being able to accommodate multiple simultaneous transmissions on a single channel, non-orthogonal multiple access (NOMA) appears as an attractive solution to support massive machine type communication (mMTC) that faces a massive number of devices competing to access the limited number of shared radio resources. In this paper, we first analytically study the throughput performance of NOMA-based random access (RA), namely NOMA-RA. We show that while increasing the number of power levels in NOMA-RA leads to a further gain in maximum throughput, the growth of throughput gain is slower than linear. This is due to the higher-power dominance characteristic in power-domain NOMA known in the literature. We explicitly quantify the throughput gain for the very first time in this paper. With our analytical model, we verify the performance advantage of the proposed NOMA-RA scheme by comparing with the baseline multi-channel slotted ALOHA (MS-ALOHA), with and without capture effect. Despite the higher-power dominance effect, the maximum throughput of NOMA-RA with four power levels achieves over three times that of the MS-ALOHA. However, our analytical results also reveal the sensitivity of load on the throughput of NOMA-RA. To cope with the potential bursty traffic in mMTC scenarios, we propose adaptive load regulation through a practical user barring algorithm. By estimating the current load based on the observable channel feedback, the algorithm adaptively controls user access to maintain the optimal loading of channels to achieve maximum throughput. When the proposed user barring algorithm is applied, simulations demonstrate that the instantaneous throughput of NOMA-RA always remains close to the maximum throughput confirming the effectiveness of our load regulation.

Sensorless control of three phase switched reluctance motor drives using an approximate inductance model (2017)

The use of position sensors in switched reluctance motor drives presents disadvantages of decreased reliability and increased cost. This paper proposes a full speed range sensorless control method in order to simply address these issues. The rotor position, during running operation is estimated through a simplified model for the relationship between phase inductance for given current and rotor angle. Means of improving this model are also proposed. For position estimation at standstill, pulse injection is employed. The estimation of the phase standstill inductances is used in order to obtain the initial rotor position. The proposed method does not require a detailed knowledge of magnetic characteristics of the motor nor additional hardware. Simulation and experimental results demonstrate the satisfactory accuracy of rotor position estimation with an error of only 0.5 degrees under high load conditions.
Bridging the Gap between Zeolites and Dense Silica Polymorphs: Formation of All‐Silica Zeolite with High Framework Density from Natural Layered Silicate Magadiite (2023)

A silica zeolite (RWZ-1) with a very high framework density (FD) was synthesized from highly crystalline natural layered silicate magadiite, bridging the gap between the two research areas of zeolites and dense silica polymorphs. Magadiite was topotactically converted into a 3D framework through two-step heat treatment. The resulting structure had a 1D micropore system of channel-like cavities with an FD of 22.1 Si atoms/1000 Å<sup>3</sup> . This value is higher than those of all other silica zeolites reported so far, approaching those of silica polymorphs (tridymite (22.6) and α-quartz (26.5)). RWZ-1 is a slight negative thermal expansion material with thermal properties approaching those of dense silica polymorphs. It contributes to the creation of a new field on microporous high-density silica/silicates. Synergistic interactions are expected between the micropores with molecular sieving properties and the dense layer-like building units with different topologies which provide thermal and mechanical stabilities.
G0301401 Method for Fatigue Life Evaluation in Aluminium Alloy Welding using Strain Singularity Parameters (2015)

Welded structures are widely used for construction machines, automobiles, railway vehicles, etc. In these structures, the welded parts are generally the weakest points. In particular, the toes of welded and the tops of non-welded and welded cracks become causes of welding fractures because these are stress concentration points. Thus, a method for fatigue life evaluation that can evaluate these stress concentration points in a lump is required. In this study, a new evaluation method for welded parts using strain singularity parameters was developed. The conclusions are as follows: (a) Comparing strain approximation equation Δε = H_εr^<-λε> (Δε: Amplitude of elastic strain, r: Distance from stress concentration part, H_ε: Magnitude of strain singularity, λ_ε: Broadening of strain singularity) to the strain distribution of test specimens calculated using elastro-plastic analysis, the strain singularity parameters H_ε and λ_ε were derived. Using the parameters and fatigue life data that was obtained from the fatigue testing of V-groove specimens (Simulated crack length: 3-8 mm, non-offsetted), a fatigue-life surface was derived. The equation of the surface was logN=-5.3146logH_ε-4.3048λ_ε+21.6888. (b)After comparing the fatigue life calculated by the fatigue-life surface equation and the fatigue life derived by all types of specimens fatigue testing, the calculated fatigue life had approximately good agreement with the fatigue life derived in the test.
The European CRT Survey: 1 Year (9–15 Months) Follow-Up Results (2011)

Outcomes including death and hospitalization in this European CRT survey were consistent with results from clinical trials of CRT. At 1 year follow-up, most patients who received a CRT device considered their symptoms improved compared with their pre-implant assessment. Although prospective, this is an observational study of successful CRT implantations, and outcomes in subgroup analyses must be interpreted with appropriate conservatism.
Drawing Causal Inference from Big Data (2015)

This colloquium was motivated by the exponentially growing amount of information collected about complex systems, colloquially referred to as “Big Data”. It was aimed at methods to draw causal inference from these large data sets, most of which are not derived from carefully controlled experiments. Although correlations among observations are vast in number and often easy to obtain, causality is much harder to assess and establish, partly because causality is a vague and poorly specified construct for complex systems. Speakers discussed both the conceptual framework required to establish causal inference and designs and computational methods that can allow causality to be inferred. The program illustrates state-of-the-art methods with approaches derived from such fields as statistics, graph theory, machine learning, philosophy, and computer science, and the talks will cover such domains as social networks, medicine, health, economics, business, internet data and usage, search engines, and genetics. The presentations also addressed the possibility of testing causality in large data settings, and will raise certain basic questions: Will access to massive data be a key to understanding the fundamental questions of basic and applied science? Or does the vast increase in data confound analysis, produce computational bottlenecks, and decrease the ability to draw valid causal inferences?
Heat resistance and flammability of high performance fibres: A review (2002)

Abstract The heat and flame resistance of high performance fibres are reviewed according to the literature data. The performance is discussed considering the physical and chemical structure of the fibres. Some selected high performance fibres are then evaluated using the cone calorimeter as a fire model to provide realistic data on the fire behaviour of the fibres. They are also examined in terms of heat resistance using combined TGA/DSC. The results are discussed and compared with literature data. Heterocyclic rigid‐rod polymers (poly (p‐phenylene‐2,6‐benzobisoxazole or PBO (Zylon ® ) and poly(2,6‐diimidazo (4,5‐b:4′,5′‐e) pyridinylene‐1,4 (2,5‐dihydroxy) phenylene or PIPD (M5)) exhibit the best performance (little or contribution to fire, low smoke and good heat resistance) and offer a good combination between heat and flame resistance and mechanical properties.

Insights into the elastic properties of RE-i-MAX phases and their potential exfoliation into two-dimensional RE-i-MXenes (2020)

The recent discovery of quaternary MAX phases with chemical in-plane order allowed the addition of nontraditional MAX phase elements, such as rare-earth elements. In the present study, first-principles calculations are performed to investigate the electronic structure, elastic and hardness response, and bonding strengths of the novel $\mathrm{RE}\text{\ensuremath{-}}i\text{\ensuremath{-}}\mathrm{MAX}$ phases with the formula ${({\text{Mo}}_{2/3}{\text{RE}}_{1/3})}_{2}\text{AlC}$. The Voigt-Reuss-Hill bulk, shear, and Young's moduli are compared along the series of RE = Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, and Lu, and the global trend is found to depend on the unit cell volume. Nanoindentation experiments on Ho-based single crystals result in moduli that are within 10% of predicted values and a hardness of $\ensuremath{\sim}10$ GPa. The computation of the projected density of states, projected crystal orbital Hamilton population, and integrated projected crystal orbital Hamilton population, reveals that the bonding of Mo and RE atoms with the Al atoms are weaker than those with the C atoms, suggesting the exfoliation of $\mathrm{RE}\text{\ensuremath{-}}i\text{\ensuremath{-}}\mathrm{MAX}$ into two-dimensional $\mathrm{RE}\text{\ensuremath{-}}i$-MXenes to be feasible. Such a possibility to form two-dimensional crystals is further confirmed by the computation of the exfoliation energies, which demonstrates the process to be easier as the RE atomic mass decreases.
Friction stir scribe welding technique for dissimilar joining of aluminium and galvanised steel (2017)

Friction stir scribe technology, a derivative of friction stir welding, was applied for the dissimilar lap welding of an aluminium alloy and galvanised mild steel sheets. During the process, the rotating tool with a cobalt steel scribe first penetrated the top material – aluminium – and then the scribe cuts the bottom material – steel. The steel was displaced into the upper material to produce a characteristic hook feature. Lap welds were shear tested, and their fracture paths were studied. Welding parameters affected the welding features, including hook height, which turned out to be highly related to fracture position. Therefore, in this paper, the relationships among welding parameters, hook height, joint strength and fracture position are presented. In addition, the influence of zinc coating on joint strength was also studied.
Pseudo-random modulation for multiple 3D time-of-flight camera operation (2013)

3D time-of-flight depth cameras utilize modulated light sources to detect the distance to objects as phase information. A serious limitation may exist in cases when multiple depth time-of-flight cameras are imaging the same scene simultaneously. The interference caused by the multiple modulated light sources can severely distort captured depth images. To prevent this problem and enable concurrent 3D multi-camera imaging, we propose modulating the camera light source and demodulating the received signal using sequences of pulses, where the phase of each sequence is varied in a pseudo-random fashion. The proposed algorithm is mathematically derived and proved by experiment.
Choice and interoperation in protocol enactment (2007)

Protocols describe interactions among agents and thus underlie the engineering of multiagent systems. However, protocols are enacted by agents in physical systems. In particular, considerations of communication models and how distributed agents are able to make compatible choices would greatly affect whether a protocol may in fact be enacted successfully. The objective of this paper is to study the conceptual underpinnings of protocol enactment in multiagent systems. It seeks to characterize the operationalization of agents so as to determine whether and when agents may be interoperable.
Heterofunctionalized Cavitands by Macrocyclization of Sequence-Defined Foldamers (2019)

Macrocyclic hosts have long been the workhorses of molecular recognition. Despite the widespread use of container-shaped molecules as synthetic receptors, an efficient preparation of cavitands bearing multiple functional groups has not been realized. This Letter describes a new cavitand derived from a sequence-defined oligoamide foldamer scaffold. A solid-phase synthesis approach is reported, which enables the display of multiple chemically diverse functional groups on the cavitand rim.

Venomics Reveals Venom Complexity of the Piscivorous Cone Snail, Conus tulipa (2019)

The piscivorous cone snail <i>Conus tulipa</i> has evolved a net-hunting strategy, akin to the deadly <i>Conus geographus</i>, and is considered the second most dangerous cone snail to humans. Here, we present the first venomics study of <i>C. tulipa</i> venom using integrated transcriptomic and proteomic approaches. Parallel transcriptomic analysis of two <i>C. tulipa</i> specimens revealed striking differences in conopeptide expression levels (2.5-fold) between individuals, identifying 522 and 328 conotoxin precursors from 18 known gene superfamilies. Despite broad overlap at the superfamily level, only 86 precursors (11%) were common to both specimens. Conantokins (NMDA antagonists) from the superfamily B1 dominated the transcriptome and proteome of <i>C. tulipa</i> venom, along with superfamilies B2, A, O1, O3, con-ikot-ikot and conopressins, plus novel putative conotoxins precursors T1.3, T6.2, T6.3, T6.4 and T8.1. Thus, <i>C. tulipa</i> venom comprised both paralytic (putative ion channel modulating α-, ω-, μ-, δ-) and non-paralytic (conantokins, con-ikot-ikots, conopressins) conotoxins. This venomic study confirms the potential for non-paralytic conotoxins to contribute to the net-hunting strategy of <i>C. tulipa.</i>
Chiral Balls: Knotted Structures with Both Chirality and Three-dimensional Rotational Symmetry (2019)

Knots have been put forward to explain various physical phenomena because of their topological stability. Nevertheless, few works have reported on the exotic symmetry properties that certain knots possess. Here we reveal an exceptional form of symmetry for a family of knots that are both chiral and three-dimensional (3-D) rotationally symmetric about every axis of a standard Cartesian coordinate system. We call these unique knotted structures chiral balls. To demonstrate the unprecedented physical characteristics exhibited by these unique structures, we study the electromagnetic scattering properties of a representative conductive chiral ball. In particular, a characteristic mode analysis is performed to investigate the intrinsic scattering properties of this chiral ball. With both chirality and 3-D rotational symmetry, the chiral ball is shown to exhibit an extraordinary isotropic circularly polarized scattering property, which has not been previously reported for any known electromagnetic structures. Because of their unique properties, chiral balls are expected to not only have a profound impact on the fields of electromagnetics and optics but also far beyond.
Col4a3-/- Mice on Balb/C Background Have Less Severe Cardiorespiratory Phenotype and SGLT2 Over-Expression Compared to 129x1/SvJ and C57Bl/6 Backgrounds (2022)

Alport syndrome (AS) is a hereditary renal disorder with no etiological therapy. In the preclinical <i>Col4a3<sup>-/-</sup></i> model of AS, disease progression and severity vary depending on mouse strain. The sodium-glucose cotransporter 2 (SGLT2) is emerging as an attractive therapeutic target in cardiac/renal pathologies, but its application to AS remains untested. This study investigates cardiorespiratory function and SGLT2 renal expression in <i>Col4a3<sup>-/-</sup></i> mice from three different genetic backgrounds, 129x1/SvJ, C57Bl/6 and Balb/C. male <i>Col4a3<sup>-/-</sup></i> 129x1/SvJ mice displayed alterations consistent with heart failure with preserved ejection fraction (HFpEF). Female, but not male, C57Bl/6 and Balb/C <i>Col4a3<sup>-/-</sup></i> mice exhibited mild changes in systolic and diastolic function of the heart by echocardiography. Male C57Bl/6 <i>Col4a3<sup>-/-</sup></i> mice presented systolic dysfunction by invasive hemodynamic analysis. All strains except Balb/C males demonstrated alterations in respiratory function. SGLT2 expression was significantly increased in AS compared to WT mice from all strains. However, cardiorespiratory abnormalities and SGLT2 over-expression were significantly less in AS Balb/C mice compared to the other two strains. Systolic blood pressure was significantly elevated only in mutant 129x1/SvJ mice. The results provide further evidence for strain-dependent cardiorespiratory and hypertensive phenotype variations in mouse AS models, corroborated by renal SGLT2 expression, and support ongoing initiatives to develop SGLT2 inhibitors for the treatment of AS.
