Cost and Yield Estimation-A New TCAD Component (1994)

A methodology to include cost and yield estimation in a comprehensive TCAD model of semiconductor processing is presented. The underlying idea is that a process recipe used to drive TCAD simulators contains a complete set of information about the process. If it is combined with empirical equipment data, a set of models can be constructed to describe cost as a function of the process recipe and equipment data. This paper presents a user-configurable cost modeling tool tightly integrated with TCAD simulators, enabling the user to study related and important questions of cost and yield not covered by traditional TCAD tools.
Metamaterial and Metastructural Architectures for Novel C4ISR Devices and Sensors (2015)

Abstract : We have developed novel metamaterial devices and metastructures with new electronic and optoelectronic (OE) properties and used them to design and fabricate devices, such as slow-light, low-loss waveguides, terahertz modulators, and wideband radio frequency (RF) antennas with new functionalities. These devices will provide basic building blocks for future chip-scale semiconductor-integrated OE circuits and provide new capabilities over a wide range of frequencies from microwaves, terahertz, and into the infrared in Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance systems. We focused on 3 different types of metamaterial devices as basic building blocks. These are low-loss, slow-light, hollow-core metastructure waveguides for chip-scale-integrated OE/RF photonic circuit; metamaterial devices for terahertz communication/sensing/imaging; and tunable RF metamaterials. Some of our major accomplishments in this area of study include developing and demonstrating the world s first silicon-based slow-light metastructure hollow-core waveguide, developing and demonstrating new tunable terahertz metamaterial devices, and designing and fabricating terahertz metastructure hollow-core waveguide. The DSI project has resulted in 14 publications, 1 US patent, 1 invention disclosure, and 1 press release.
Synthesis, Structure, and Optical Properties of Pt(II) and Pd(II) Complexes with Oxazolyl- and Pyridyl-Functionalized DPPM-Type Ligands: A Combined Experimental and Theoretical Study (2014)

New square-planar complexes [Pt(1(-H))2] (2a) [1(-H) = (oxazolin-2-yl)bis(diphenylphosphino)methanide] and [Pd(1(-H))2] (2b), of general formula [M{(Ph2P)2C---C---NCH2CH2O}2] (M = Pt, 2a; M = Pd, 2b), result from deprotonation of 2-{bis(diphenylphosphino)methyl}oxazoline (1) at the PCHP site. The new, functionalized dppm-type ligand 4-{bis(diphenylphosphino)methyl}pyridine, (Ph2P)2CH(4-C5H4N) (4), was prepared by double lithiation and phosphorylation of 4-picoline. In the presence of NEt3, the reactions of 2 equiv of 4 with [PtCl2(NCPh)2] and [Pd(acac)2] (acac = acetylacetonate) afforded [Pt(4(-H))2] (5a) [4(-H) = bis(diphenylphosphino)(pyridin-4-yl)methanide] and [Pd(4(-H))2] (5b), of general formula [M{(Ph2P)2C(4-C5H4N)}2] (M = Pt, 5a; M = Pd, 5b), respectively. In the absence of base, the reactions of 2 equiv of 4 with [PtCl2(NCPh)2] and [PdCl2(NCPh)2] afforded (5a·2HCl) (6a) and (5b·2HCl) (6b), respectively, in which the PCHP proton of 4 has migrated from carbon to nitrogen to give a pyridinium derivative of general formula [M{(Ph2P)2C(4-C5H4NH)}2]Cl2 (M = Pt, 6a; M = Pd, 6b). The complexes 3a, 5a·2MeOH, and 6b·4CH2Cl2 have been structurally characterized by X-ray diffraction. The absorption/emission properties of the Pt(II) complexes 2a and 5a and the Pd(II) complexes 2b and 5b have been investigated by UV-vis spectroscopy and theoretical analysis based on density functional theory. The UV-vis absorption spectra of the neutral complexes recorded in dilute N,N'-dimethylformamide solutions are dominated by intense spin-allowed intraligand transitions in the region below 350 nm. The complexes exhibit charge-transfer bands between 350 and 500 nm. The experimental and theoretical absorption spectra agree qualitatively and point to two low-lying ligand-to-metal charge transfer states that contribute to the bands observed between 350 and 500 nm. The complexes are emissive in frozen solutions at 77 K, in the pure solid state, and when doped into films of poly(methyl methacrylate) but are nonemissive in solution. A red shift is observed when Pt(II) is replaced by Pd(II).
Observation of the Dynamics of a Focal Spot Using a Long-Pulse Linear Induction Accelerator (2020)

A diagnostic has been developed to study the focusing dynamics of a high-power electron beam on a target. The diagnostic uses a pinhole camera to observe bremsstrahlung from the converter target. A data acquisition system yields images of the beam focal spot with a frame duration of 20 ns and an almost unlimited recording duration. The focal spot dynamics of a linear induction accelerator with an energy of 1.5 MeV, a current of 1.2 kA and a pulse duration of 350 ns were studied. The focal spot was found to be disrupted within the first 100 ns of the pulse. Defocusing has a complex 3-D character. The feasibility of additional cleaning of the target using an accelerator pre-pulse was shown. Stable beam focusing for up to 200 ns was demonstrated.
Concept for fast breast cancer ultrasound screening in addition to mammography – first clinical results (2019)

In breast cancer screening, x-ray mammography is the standard imaging modality. For clarification of suspicious findings, handheld ultrasound (US) is used as an adjunct modality. It is so far not included in screening due to the lack of standardization, high costs and the risk of increased false positives within screening population. First attempts to standardize US with automated breast US are still not completely fulfilling clinical needs, e.g. workflow and reading are claimed not to be fast enough. Therefore, various groups introduced new concepts of fast US screening, providing standardized images in the same orientation as the mammography images, leading to a speed-up of reading and reporting.To acquire US images in an x-ray mammography environment, an automated breast US transducer was inserted into a modified compression paddle. After mammography or tomosynthesis, an automated breast US scan was performed. We investigated new concepts to optimize workflow speed and approaches to achieve nearly full US coverage of the breast in a clinical study.We successfully integrated automated US scanning in a clinical workflow with less than one minute for the additional scan. Compared to the workflows of automated breast US and handheld US, the proposed scanning concept provides a high time and cost saving potential. Preliminary results indicate a high breast area coverage of the US scan. The first clinical results of our method demonstrated a proof of concept for a technical solution to include US screening into the standard breast cancer screening workflow. The standard workflow is changed minimally and the additional time investment is low since no patient repositioning or system adjustments are needed between both scanning modalities.
Cu‐Catalyzed Enantioselective Conjugate Additions of Alkyl Zinc Reagents to UnsaturatedN‐Acyloxazolidinones Promoted by a Chiral Triamide Phosphane (2003)

A chiral triamide phosphane promotes highly efficient and enantioselective Cu-catalyzed conjugate additions of alkyl zinc compounds to unsaturated oxazolidinones (see scheme). The resulting β-alkyl chiral oxazolidinones are readily converted into synthetically useful carbonyl compounds not accessible by alternative catalytic methods.

Novel Contrast Mechanisms at High Field 1 (2008)

This article reviews the technical principles of novel contrast mechanisms for musculoskeletal imaging. Ultrashort echo-time imaging allows the visualization of fast T2 relaxing tissue components that are not directly detectable by standard magnetic resonance imaging. This offers several new applications, especially in musculoskeletal imaging, to visualize these tissue components directly. Magnetization transfer techniques, which have been successfully applied to assess demyelinization processes in white brain matter, for example, can be used to detect the integrity of the collagen network of cartilage, and they may help for the detection of early cartilage degradations. Finally, diffusion-weighted imaging represents a further technique to detect bone marrow pathologies or indicate collagen degradation and water content in cartilage. The technical details and implementation techniques of these dedicated imaging modalities are demonstrated and reviewed in this article, and some clinical examples are presented.
Experimental and quantum‐chemical studies of 15N NMR coordination shifts in palladium and platinum chloride complexes with pyridine, 2,2′‐bipyridine and 1,10‐phenanthroline (2006)

A series of Pd and Pt chloride complexes with pyridine (py), 2,2'-bipyridine (bpy) and 1,10-phenanthroline (phen), of general formulae trans-/cis-[M(py)2Cl2], [M(py)4]Cl2, trans-/cis-[M(py)2Cl4], [M(bpy)Cl2], [M(bpy)Cl4], [M(phen)Cl2], [M(phen)Cl4], where M = Pd, Pt, was studied by 1H, 195Pt, and 15N NMR. The 90-140 ppm low-frequency 15N coordination shifts are discussed in terms of such structural features of the complexes as the type of platinide metal, oxidation state, coordination sphere geometry and the type of ligand. The results of quantum-chemical NMR calculations were compared with the experimental 15N coordination shifts, well reproducing their magnitude and correlation with the molecular structure.
Palladium catalytic system for inhibition of O-arylation type reaction and regioselective direct arylation at C2 of phenols (2011)

The palladium-catalysed arylation of free OH phenol derivatives proceeds regioselectively either at C2 or at OH with a variety of electron-deficient aryl bromides or heteroaryl bromides. The nature of the base was found to be crucial to control the regioselectivity of the reaction. In the presence of potassium acetate, the direct arylation at C2 is favoured; whereas, under the same reaction conditions, the use of potassium carbonate gave selectively the O-arylation type products.

Cardiac catheterization, cardiac surgery, and the newborn infant-1969. (1969)

Surgical successes in newborn infants with critical cardiac defects challenge pediatricians, pediatric cardiologists, and thoracic surgeons to recognize, diagnose, and correct these lesions. The report of Varghese and his colleagues documenting the management of 100 consecutive infants with apparently life-threatening cardiac malformations will be of interest to all concerned. Such newborn infants present formidable problems. The difficulties of recognizing which infant has a naturally fatal lesion, the suddenness and rapidity with which the clinical course may shift downwards, the logistics of transferring a sick infant to a center equipped and staffed for emergency cardiac catheterization and emergency surgery, the technical difficulties of miniaturizing equipment for cardiac catheterization and cardiac surgery, and the inherent risks of diagnostic catheterization and cardiac surgery in seriously ill babies are sobering obstacles.
Surface-Enhanced Raman Spectroelectrochemistry of TTF-Modified Self-Assembled Monolayers (2015)

Surface-enhanced Raman spectroscopy (SERS) was used to monitor the response of a self-assembled monolayer (SAM) of a tetrathiafulvalene (TTF) derivative on a gold film-over-nanosphere electrode. The electrochemical response observed was rationalized in terms of the interactions between TTF moieties as the oxidation state was changed. Electrochemical oxidation to form the monocation caused the absorbance of the TTF unit to coincide with both the laser excitation wavelength and the localized surface plasmon resonance (LSPR), resulting in surface-enhanced resonance Raman scattering (SERRS). The vibrational frequency changes that accompany electron transfer afford a high-contrast mechanism that can be used to determine the oxidation state of the TTF unit in an unambiguous manner.

Design-time application mapping and platform exploration for MP-SoC customised run-time management (2007)

In an Multi-Processor system-on-Chip (MP-SoC) environment, a customized run-time management layer should be incorporated on top of the basic Operating System services to alleviate the run-time decision-making and to globally optimise costs (e.g. energy consumption) across all active applications, according to application constraints (e.g. performance, user requirements) and available platform resources. To that end, to avoid conservative worst-case assumptions, while also eliminating large run-time overheads on the state-of-the-art RTOS kernels, a Pareto-based approach is proposed combining a design-time application and platform exploration with a low-complexity run-time manager. The design-time exploration phase of this approach is the main contribution of this work. It is also substantiated with two real-life applications (image processing and video codec multimedia). These are simulated on MP-SoC platform simulator and used to illustrate the optimal trade-offs offered by the design-time exploration to the run-time manager.
Oronasal or Intramuscular Immunization with a Thermo-Attenuated ASFV Strain Provides Full Clinical Protection against Georgia 2007/1 Challenge (2022)

African swine fever (ASF) is a contagious viral disease of suids that induces high mortality in domestic pigs and wild boars. Given the current spread of ASF, the development of a vaccine is a priority. During an attempt to inactivate the Georgia 2007/1 strain via heat treatment, we fortuitously generated an attenuated strain called ASFV-989. Compared to Georgia, the ASFV-989 strain genome has a deletion of 7458 nucleotides located in the 5'-end encoding region of MGF 505/360, which allowed for developing a DIVA PCR system. <i>In vitro</i>, in porcine alveolar macrophages, the replication kinetics of the ASFV-989 and Georgia strains were identical. <i>In vivo</i>, specific-pathogen-free (SPF) pigs inoculated with the ASFV-989 strain, either intramuscularly or oronasally, exhibited transient hyperthermia and slightly decreased growth performance. Animals immunized with the ASFV-989 strain showed viremia 100 to 1000 times lower than those inoculated with the Georgia strain and developed a rapid antibody and cell-mediated response. In ASFV-989-immunized pigs challenged 2 or 4 weeks later with the Georgia strain, no symptoms were recorded and no viremia for the challenge strain was detected. These results show that the ASFV-989 strain is a promising non-GMO vaccine candidate that is usable either intramuscularly or oronasally.

Multi-Gaussian fitting for the assessment of left ventricular ejection time from the Photoplethysmogram (2012)

The Left ventricular ejection time (LVET) is one of the primary surrogates of the left ventricular contractility and stroke volume. Its continuous monitoring is considered to be a valuable hypovolumia prognostic parameter and an important risk predictor in cardiovascular diseases such as cardiac and light chain amyloidosis. In this paper, we present a novel methodology for the assessment of LVET based the Photoplethysmographic (PPG) waveform. We propose the use of Gaussian functions to model both systolic and diastolic phases of the PPG beat and consequently determine the onset and offset of the systolic ejection from the analysis of the systolic phase 3(rd) derivative. The results achieved by the proposed methodology were compared with the algorithm proposed by Chan et al. [1], revealing better estimation of LVET (15.84 ± 13.56 ms vs 23.01 ± 14.60 ms), and similar correlation with the echocardiographic reference (0.73 vs 0.75).

Analysis of 4500 V double trench MOS controlled thyristor (2002)

Novel high voltage MOS controlled thyristor (MCT) structures are proposed and analysed. It was found that the double trench MCT(DTMCT) increases the turn-off capability by a factor of 4 and reduces the turn-off loss by a factor of 5 compared with single trench gate MCT(TMCT) while both have a forward blocking voltage of 4500 V. These results, combined with the excellent forward current carrying capability provided by thyristor operation, are encouraging for the DTMCT to be developed for very high voltage low loss applications.
Origin of the Thermoreversible fcc-bcc Transition in Block Copolymer Solutions (2004)

The thermoreversible fcc-bcc transition in concentrated block copolymer micellar solutions is shown to be driven by decreases in the aggregation number as the solvent penetrates the core, leading to a softer intermicelle potential. Small-angle neutron scattering measurements in a dilute solution are used to quantify the temperature-dependent micellar characteristics. The observed phase boundary is in excellent agreement with recent simulations of highly branched star polymers.
Detrimental Impact of Na Upon Rb Postdeposition Treatments of Cu(In,Ga)Se2 Absorber Layers (2021)

Postdeposition Treatment In article number 2100390, Jessica de Wild and co-workers performed a RbF postdeposition treatment on AlOx back-passivated Cu(In,Ga)Se2 solar cells. It is found that Na present at the AlOx/Mo back contact inhibits Rb diffusion into the absorber layer. A detrimental redistribution of the alkali follows, leading to an injection barrier at the front and reduction of the acceptor concentration in the bulk.

Event shape variables measured using multijet final states in proton-proton collisions at $$ \sqrt{s}=13 $$ TeV (2018)

A bstract The study of global event shape variables can provide sensitive tests of predictions for multijet production in proton-proton collisions. This paper presents a study of several event shape variables calculated using jet four momenta in proton-proton collisions at a centre-of-mass energy of 13 TeV and uses data recorded with the CMS detector at the LHC corresponding to an integrated luminosity of 2.2 fb −1 . After correcting for detector effects, the resulting distributions are compared with several theoretical predictions. The agreement generally improves as the energy, represented by the average transverse momentum of the two leading jets, increases.
Principle and applications of asymmetric crosstalk-resistant adaptive noise canceller (2003)

This paper analyzes the performance of the crosstalk-resistant adaptive noise canceller (CTRANC). The CTRANC system's symmetric structure causes inconsistent performance when treating noise coming from different incident angles. To solve this problem, an asymmetric CTRANC (ACTRANC) structure using a delay unit on the primary channel is proposed. The ACTRANC allows flexible alignment of the noise source with the sensor array in advanced communication applications such as adaptive noise cancellation, acoustic echo cancellation and adaptive beamforming.
