Vehicle Longitudinal Control Using Discrete Markers (1994)

In this report, a hybrid observer is proposed as a method of estimating position and velocity of a vehicle when the primary output is a series of discrete magnetic markers placed along a roadway. For the preliminary studies, the vehicle was modeled as a pure inertial system with acceleration input. Two methods of determining the time "tk" at which the "k-th" marker is passed are discussed, and simulations using both methods are shown. Compensation for errors arising due to inaccurate measurement of this time is proposed and validated. A Proportional- Integral-Derivative (PID) controller acting on error signals from the hybrid observer is also developed and simulated. An "optimal" trajectory for marker advance/fallback and velocity change commands is calculated and verified in simulation, and its effects on the PID controller are discussed.
Vibrational coherence transfer in the ultrafast intersystem crossing of a diplatinum complex in solution (2018)

We investigate the ultrafast transient absorption response of tetrakis(μ-pyrophosphito)diplatinate(II), [Pt<sub>2</sub>(μ-P<sub>2</sub>O<sub>5</sub>H<sub>2</sub>)<sub>4</sub>]<sup>4-</sup> [hereafter abbreviated Pt(pop)], in acetonitrile upon excitation of its lowest singlet <sup>1</sup>A<sub>2u</sub> state. Compared with previously reported solvents [van der Veen RM, Cannizzo A, van Mourik F, Vlček A, Jr, Chergui M (2011) <i>J Am Chem Soc</i> 133:305-315], a significant shortening of the intersystem crossing (ISC) time (<1 ps) from the lowest singlet to the lowest triplet state is found, allowing for a transfer of vibrational coherence, observed in the course of an ISC in a polyatomic molecule in solution. Density functional theory (DFT) quantum mechanical/molecular mechanical (QM/MM) simulations of Pt(pop) in acetonitrile and ethanol show that high-lying, mostly triplet, states are strongly mixed and shifted to lower energies due to interactions with the solvent, providing an intermediate state (or manifold of states) for the ISC. This suggests that the larger the solvation energies of the intermediate state(s), the shorter the ISC time. Because the latter is smaller than the pure dephasing time of the vibrational wave packet, coherence is conserved during the spin transition. These results underscore the crucial role of the solvent in directing pathways of intramolecular energy flow.
ETBR: Extended Truncated Balanced Realization Method for On-Chip Power Grid Network Analysis (2008)

In this paper, we present a novel simulation approach for power grid network analysis. The new approach, called ETBR for extended truncated balanced realization, is based on model order reduction techniques to reduce the before the simulation. Different from the (improved) extended Krylov subspace methods EKS/IEKS [15, 2], ETBR performs fast truncated balanced realization on response Grammian to reduce the original system with the similar computation costs of EKS. ETBR also avoids the adverse explicit moment representation of the input signals. Instead, it uses spectrum representation of input signals by fast Fourier transformation. As a result, ETBR is more flexible for different types of input sources and can better capture the high frequency contents than EKS, and this leads to more accurate results especially for fast changing input signals. Experimental results on a number of large networks (up to one million nodes) show that, given the same order of the reduced model, ETBR is indeed more accurate than the EKS method especially for input sources rich in high-frequency components. ETBR also shows similar computation costs of EKS and less memory consumption than EKS.
Smart CMOS temperature sensors (2009)

Summery form only given. Smart sensors are systems in which sensors and dedicated interface electronics are integrated on the same chip, or at least in the same package. Due to the low-level analog output of typical sensors, designing interface electronics that ldquodoes no harmrdquo, i.e. does not impair sensor performance, is quite challenging, especially in today's mainstream CMOS technology, whose inherent precision is limited by 1/f noise and component mismatch. However, since most sensors are quite slow compared to transistors, dynamic techniques can often be used to trade speed or bandwidth for higher precision. Examples of such techniques are auto zeroing, chopping, dynamic element matching, switched-capacitor filtering and sigma-delta modulation. This paper describes the use of such dynamic techniques in the design and realization of state-of-the-art smart CMOS temperature sensors.

Study of Failure Pattern Among High-Risk Breast Cancer Patients With or Without Postmastectomy Radiotherapy in Addition to Adjuvant Systemic Therapy: Long-Term Results From the Danish Breast Cancer Cooperative Group DBCG 82 b and c Randomized Studies (2006)

Postmastectomy RT changes the disease recurrence pattern in high-risk breast cancer patients; fewer patients have LRR as first site of recurrence, and overall fewer patients have DM.
Morphogen-Based Chemical Flypaper for Agaricia humilis Coral Larvae (1994)

Larvae of the scleractinian coral Agaricia humilia settle and metamorphose in response to chemosensory recognition of a morphogen on the surfaces of Hydwlithon boergesenii and certain other crustose coralline red algae.The requirement of the larva for this inducer apparently helps to determine the spatial pattern of recruitment in the natural environment.Previous research showed that the inducer is associated with the insoluble cell wall fraction of the recruiting algae or their microbial epibionts, and that a soluble but unstable fragment of the inducing molecule can be liberated by limited hydrolysis, either with alkali or with enzymes specific for cell wall polysaccharides.We now show that the parent morphogen can be solubilized by gentle decalcification of the algal cell walls with the chelators EGTA or EDTA, suggesting that the morphogen may be a component of the calcified recruiting alga itself, rather than a product of any noncalcified microbial epibionts.The solubilized inducer is subsequently purified by hydrophobic-interaction and DEAE chromatography.The purified, amphipathic morphogen retains activity when tightly bound to beads of a hydrophobic-interaction chromatography resin, and this activity (tested with laboratory-reared larvae) is identical in the ocean and the laboratory.We have attached the purified, resin-bound inducer to surfaces coated with a silicone adhesive and thus produced a potent artificial recruiting substratum -i.e.. a morphogen-based chemical
Topoisomerase Inhibitors Addressing Fluoroquinolone Resistance in Gram-Negative Bacteria (2020)

Since their discovery over 5 decades ago, quinolone antibiotics have found enormous success as broad spectrum agents that exert their activity through dual inhibition of bacterial DNA gyrase and topoisomerase IV. Increasing rates of resistance, driven largely by target-based mutations in the GyrA/ParC quinolone resistance determining region, have eroded the utility and threaten the future use of this vital class of antibiotics. Herein we describe the discovery and optimization of a series of 4-(aminomethyl)quinolin-2(1<i>H</i>)-ones, exemplified by <b>34</b>, that inhibit bacterial DNA gyrase and topoisomerase IV and display potent activity against ciprofloxacin-resistant Gram-negative pathogens. X-ray crystallography reveals that <b>34</b> occupies the classical quinolone binding site in the topoisomerase IV-DNA cleavage complex but does not form significant contacts with residues in the quinolone resistance determining region.
Two graphical methods for planar contact problems (2002)

Graphical methods are often applied to planar mechanics problems, especially in the context of robotic manipulation, but there are limitations. In particular, the friction cone is an elegant representation of the set of forces generated by a single frictional contact, but there was previously no simple extension to problems of multiple frictional contacts. The paper shows a simple generalization of the friction cone to include multiple contacts. It demonstrates applications to dynamics problems and manipulation planning problems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Total Ankle Arthroplasty Accuracy and Reproducibility Using Preoperative CT Scan-Derived, Patient-Specific Guides (2014)

We have further demonstrated that final implant position is successfully guided by these patient-specific guides, with reproducibility of tibial component placement falling within 2 degrees of the intended target. This level of reproducibility suggests a promise for this technology, and it is hoped this level of accuracy will become the benchmark for the next generation of total ankle arthroplasty.
Patients’ and health care providers’ perspectives on quality of hemophilia care in the Netherlands: a questionnaire and interview study (2023)

Satisfaction with hemophilia care is high among persons with hemophilia in the Netherlands, although several potential improvements have been identified. Accentuating these is especially relevant in the current era of treatment innovations, in which we might focus less on other aspects of care.
Region-of-interest reconstruction on medical C-arms with the ATRACT algorithm (2012)

Between 2006 and 2008, the business volume of the top 20 orthopedic manufacturers increased by 30% to about $35 Billion. Similar growth rates could be observed in the market of neurological devices, which went up in 2009 by 10.9% to a volume of $2.2 Billion in the US and by 7.0% to 500 Million in Europe.* These remarkable increases are closely connected to the fact that nowadays, many medical procedures, such as implantations in osteosynthesis or the placement of stents in neuroradiology can be performed using minimally-invasive approaches. Such approaches require elaborate interoperative imaging technology. C-arm based tomographic X-ray region-of-interest (ROI) tomography can deliver suitable imaging guidance in these circumstances: it can offer 3D information in desired patient regions at reasonably low X-ray dose. Tomographic ROI reconstruction, however, is in general challenging since projection images might be severely truncated. Recently, a novel, truncation-robust algorithm (ATRACT) has been suggested for 3D C-arm ROI imaging. In this paper, we report for the first time on the performance of ATRACT for reconstruction from real, angiographic C-arm data. Our results indicate that the resulting ROI image quality is suitable for intraoperative imaging. We observe only little differences to the images from a non-truncated acquisition, which would necessarily require significantly more X-ray dose.
Plasticizer loss in a complex system (polyamide 12): Kinetics, prediction and its effects on mechanical properties (2019)

Plasticizer migration is a major concern for plasticized polymers because it leads to unwanted changes in mechanical properties and, in many cases, contamination of the environment. In cases of slow migration, it is of practical importance to be able to perform accelerated testing and estimate migration rates from high temperature experiments. Despite the importance, a critical evaluation of different ways of extrapolating mass loss data has hitherto not been reported. Therefore, in this article, three different methods (involving for the first time a master-curve approach to mass loss data) to estimate low temperature migration from high temperature data are presented and critically evaluated. The system chosen was a plasticized polyamide 12 pipe, an important component in vehicle fuel-line systems. This system was challenging since the lower part of the temperature range in which the material is used overlaps with the glass transition region. All three methods (using data at 80–145 °C) over-estimated, although to different extents, the low-temperature mass loss rate (60 °C). The main reason for the over-estimation was the partial overlap with the glass transition region. Hence, there is a built-in safety factor when predicting plasticizer loss over glass transition regions, and the predictions are conservative. It was observed that plasticizer loss and annealing effects were the main reasons for changes in mechanical properties (increase in flexural stiffness/strength) during ageing.

α4β1-dependent adhesion strengthening under mechanical strain is regulated by paxillin association with the α4-cytoplasmic domain (2005)

The capacity of integrins to mediate adhesiveness is modulated by their cytoplasmic associations. In this study, we describe a novel mechanism by which alpha4-integrin adhesiveness is regulated by the cytoskeletal adaptor paxillin. A mutation of the alpha4 tail that disrupts paxillin binding, alpha4(Y991A), reduced talin association to the alpha4beta1 heterodimer, impaired integrin anchorage to the cytoskeleton, and suppressed alpha4beta1-dependent capture and adhesion strengthening of Jurkat T cells to VCAM-1 under shear stress. The mutant retained intrinsic avidity to soluble or bead-immobilized VCAM-1, supported normal cell spreading at short-lived contacts, had normal alpha4-microvillar distribution, and responded to inside-out signals. This is the first demonstration that cytoskeletal anchorage of an integrin enhances the mechanical stability of its adhesive bonds under strain and, thereby, promotes its ability to mediate leukocyte adhesion under physiological shear stress conditions.
Compressive time-of-flight imaging (2017)

Time-of-flight (ToF) cameras are compact devices providing spatially and temporally resolved depth information. Possible applications include human-machine interaction in gaming industry or safety functions in automotive industry. In many applications, it is desirable to reduce the amount of data to be read out and transmitted from the ToF camera. Using standard ToF cameras, this can only be achieved by lowering the spatial or temporal resolution. In this paper we propose a compressive ToF camera design that allows to reduce the amount of data while keeping high spatial an temporal resolution.

224-ke Saturation signal global shutter CMOS image sensor with in-pixel pinned storage and lateral overflow integration capacitor (2017)

The required incorporation of an additional in-pixel retention node for global shutter complementary metal-oxide semiconductor (CMOS) image sensors means that achieving a large saturation signal presents a challenge. This paper reports a 3.875-μm pixel single exposure global shutter CMOS image sensor with an in-pixel pinned storage (PST) and a lateral-overflow integration capacitor (LOFIC), which extends the saturation signal to 224 ke, thereby enabling the saturation signal per unit area to reach 14.9 ke/μm. This pixel can assure a large saturation signal by using a LOFIC for accumulation without degrading the image quality under dark and low illuminance conditions owing to the PST.
Different proliferative response of human and chimpanzee lymphocytes after contact with human immunodeficiency virus type 1 gp120 (1994)

T cell functional defects are a common aspect of human immunodeficiency virus (HIV) infection. Moreover, it has been suggested that indirect mechanisms are involved in CD4+ cell depletion. Unresponsiveness to proliferative stimuli of lymphocytes incubated with HIV particles or with viral proteins is well documented. Nevertheless, drawing a clear picture of the anergy phenomenon is difficult because of several unresolved and controversial questions. Here we report that recombinant gp120 induces anergy in T helper lymphocytes cultured with different stimuli. The proliferative responses to interleukin (IL)-2, IL-4, IL-6, anti-CD2, anti-CD3 and phorbol 12-myristate 13-acetate are inhibited. Moreover, anergic cells show a different distribution in cell cycle phases as compared to control cells, leading us to suggest that the progression in the cell cycle is hampered and that a pre-mitotic block takes place. Furthermore, since chimpanzees are susceptible to HIV-1 infection without showing immunodeficiency signs, we analyzed the proliferation of chimpanzee lymphocytes without observing anergy in cells preincubated with gp120. Taken together, these results support the hypothesis that anergy plays an important role in HIV infection in vivo.

Near Real Time Discovery and Conversion of Open Source Information to a Reward Matrix (2014)

We describe a system model for determining decision making strategies based upon the ability to perform data mining and pattern discovery utilizing open source information to automatically predict the likelihood of reactions to specific events or situational awareness from multiple information sources. Within this paper, we discuss the development of a method for determining actionable information to efficiently propitiate manpower, equipment assets, or propaganda responses to multiple application case scenario experiments. In our experiments, we have integrated open source information linking to human sentiment and manipulated other user selectable interlinking relative probabilities for different reactions to different events based upon current knowledge generated from the situation or event. The goal of our solution, called GlobalSite, is to deliver trustworthy decision making analysis which evaluates situations and potential impacts of such decisions through acquired open source information becoming a vital tool for continuing mission operations, analyst information or other decision making scenarios.
Temperature-dependent quantum efficiency of Ga(N,As,P) quantum wells (2013)

The photoluminescence quantum efficiencies of a series of Ga(N,As,P)/GaP multiple quantum wells are analyzed. The external quantum efficiencies are derived from the absorbed and the emitted light intensities measured using an integrating sphere mounted inside a closed-cycle helium cryostat. By taking into account the device layer sequences as well as internal reflections and reabsorption, the internal quantum efficiencies yield values above 90% for all samples at cryogenic temperatures. The temperature-dependence of the quantum efficiencies as a function of active quantum well layer design reveal the internal interfaces as remaining growth challenge in these heterostructures.
On the Design of AI-powered Code Assistants for Notebooks (2023)

AI-powered code assistants, such as Copilot, are quickly becoming a ubiquitous component of contemporary coding contexts. Among these environments, computational notebooks, such as Jupyter, are of particular interest as they provide rich interface affordances that interleave code and output in a manner that allows for both exploratory and presentational work. Despite their popularity, little is known about the appropriate design of code assistants in notebooks. We investigate the potential of code assistants in computational notebooks by creating a design space (reified from a survey of extant tools) and through an interview-design study (with 15 practicing data scientists). Through this work, we identify challenges and opportunities for future systems in this space, such as the value of disambiguation for tasks like data visualization, the potential of tightly scoped domain-specific tools (like linters), and the importance of polite assistants.
Supplemental Material for Effects of Action Video Game Play on Cognitive Skills: A Meta-Analysis (2023)

The possibility that playing action video games is associated with enhancements in certain aspects of cognitive function has attracted significant interest from researchers in education, psychology, and neuroscience. Previous meta-analyses indicated an overall positive relationship between action video game play and cognitive skills. However, follow-up to this previous work is warranted, not only because the amount of data has grown significantly since previous meta-analyses were conducted, but also because previous work left several issues unresolved (e.g., certain meta-analytic procedures). We conducted a literature search using predefined keywords and inclusion criteria to identify studies that examined the relationship between action video game play and cognitive skills. Data from (a) 105 cross-sectional studies (221 effect sizes) and (b) 28 intervention studies with an active control group (91 effect sizes) were analyzed separately via meta-analytic models for dependent effect sizes with robust variance estimates for correlated and hierarchical effects (CHE) and small-sample corrections. Consistent with our hypotheses, action video game players outperformed nonvideo game players in the cross-sectional meta-analysis (large effect, g = 0.64, 95% CI [0.53, 0.74]). Action video game play was causally related to improvements in cognitive skills in the intervention meta-analysis (small effect, g = 0.30, 95% CI [0.11, 0.50]). Publication bias was detected in the cross-sectional data set, with sensitivity analysis showing high heterogeneous estimates of the average unbiased effect. Publication bias was not detected in the intervention data set, but sensitivity analyses also point to heterogeneity. No significant moderators were found for either data set; however, this may be limited by small sample sizes.
