An Unsupervised Machine Learning Paradigm for Artifact Removal from Electrodermal Activity in an Uncontrolled Clinical Setting (2021)

ABSTRACT Objective Electrodermal activity (EDA) reflects sympathetic nervous system activity through sweating-related changes in skin conductance. To enable EDA data to be used robustly in clinical settings, we need to develop artifact detection and removal frameworks that can handle the types of interference experienced in clinical settings. Methods We collected EDA data from 69 subjects while they were undergoing surgery in the operating room. We then built an artifact removal framework using unsupervised learning methods and informed features to remove the heavy artifact that resulted from the use of surgical electrocautery during the surgery and compared it to other existing methods for artifact removal from EDA data. Results Our framework was able to remove the vast majority of artifact from the EDA data across all subjects with high sensitivity (94%) and specificity (90%). In contrast, existing methods used for comparison struggled to be sufficiently sensitive and specific, and none effectively removed artifact even if it was identifiable. In addition, the use of unsupervised learning methods in our framework removes the need for manually labeled datasets for training. Conclusion Our framework allows for robust removal of heavy artifact from EDA data in clinical settings such as surgery. Since this framework only relies on a small set of informed features, it can be expanded to other modalities such as ECG and EEG. Significance Robust artifact removal from EDA data is the first step to enable clinical integration of EDA as part of standard monitoring in settings such as the operating room.
The role of dimensionality in the decay of surface effects (2013)

We computationally investigate the decay of surface effects in one-, two-, and three-dimensional materials using two-band tight-binding models. These general models facilitate a direct comparison between materials of differing dimensionality, which reveals that material dimensionality (not material-specific chemistry/physics) is the primary factor controlling the decay of surface effects. Our results corroborate more sophisticated, material-specific studies, finding that surface effects decay after ∼10, ∼25, and ≳ 100 layers in three-dimensional, two-dimensional, and one-dimensional materials, respectively. Physically, higher-dimensional materials screen surface effects more efficiently, as theoretically described by integration over each layer's Brillouin zone. Finally, we discuss several implications of these results.
Increased GlcNacation and decreased caveolin‐3 in cardiac myocyte caveolae during diabetes mellitus (2009)

Cardiomyopathy, independent of the vascular effects of hypertension or coronary artery disease, occurs in patients with diabetes mellitus (DM), thus suggesting that factors within cardiac myocytes contribute to DM‐associated cardiac remodeling. Caveolin‐3 (Cav‐3), a myocyte‐specific protein, localizes numerous molecules within caveolae (flask‐like invaginations of the membrane) and can modulate cardiac remodeling; Knockout of Cav‐3 in mice results in a cardiomyopathic phenotype. To test the hypothesis that post‐translational modification of caveolar proteins occur in DM, we assessed hearts from control or streptozotocin‐induced DM mice using fractionation/immunoblot analysis and electron microscopy (EM). We found that diabetic hearts have reduced Cav‐3 expression in caveolar fractions and increased O‐GlcNacation (a post‐translational modification) of caveolar‐resident proteins. EM revealed that diabetic hearts had disruption of cytoarchitecture with disorganized, rounded mitochondria and fewer caveolar invaginations. DM is thus associated with enhanced Glc‐Nacation of caveolar proteins and decreased expression of Cav‐3 in caveolae. Thus, therapies designed to enhance Cav‐3/caveolae expression are potentially novel approaches to limit DM‐associated cardiac remodeling.
A Comparison between Term-Independence Retrieval Models for Ad Hoc Retrieval (2021)

In Information Retrieval, numerous retrieval models or document ranking functions have been developed in the quest for better retrieval effectiveness. Apart from some formal retrieval models formulated on a theoretical basis, various recent works have applied heuristic constraints to guide the derivation of document ranking functions. While many recent methods are shown to improve over established and successful models, comparison among these new methods under a common environment is often missing. To address this issue, we perform an extensive and up-to-date comparison of leading term-independence retrieval models implemented in our own retrieval system. Our study focuses on the following questions: (RQ1) Is there a retrieval model that consistently outperforms all other models across multiple collections; (RQ2) What are the important features of an effective document ranking function? Our retrieval experiments performed on several TREC test collections of a wide range of sizes (up to the terabyte-sized Clueweb09 Category B) enable us to answer these research questions. This work also serves as a reproducibility study for leading retrieval models. While our experiments show that no single retrieval model outperforms all others across all tested collections, some recent retrieval models, such as MATF and MVD, consistently perform better than the common baselines.
Modeling of soft magnetic composites (2004)

The electromagnetic properties of soft magnetic composites (SMCs) are studied based on a finite element model. In this approach, SMCs are modeled as an infinite array of hexagonal cylinders in two dimensions. Each cylinder is assumed to be saturable pure iron coated with a thin layer of binder or insulation. The array is excited by a current sheet or imposed fluxes to generate static average saturation characteristics (B-H or /spl mu/-B curves). The effects of insulation thickness, particle size, composite; contact; porosity; fill base metal, contacts and porosity are evaluated by varying the parameters and geometric details of the model. In addition, preliminary studies of eddy current behavior were undertaken. They show that conductivity in SMC is not of typical nature.
Primary Electron Donor(s) in Isolated Reaction Center of Photosystem II from Chlamydomonas reinhardtii (2012)

Isolated reaction centers (RCs) from wild-type Chlamydomonas (C.) reinhardtii of Photosystem II (PSII), at different levels of intactness, were studied to provide more insight into the nature of the charge-separation (CS) pathway(s). We argue that previously studied D1/D2/Cytb559 complexes (referred to as RC680), with ChlD1 serving as the primary electron donor, contain destabilized D1 and D2 polypeptides and, as a result, do not provide a representative model system for the intact RC within the PSII core. The shapes of nonresonant transient hole-burned (HB) spectra obtained for more intact RCs (referred to as RC684) are very similar to P(+)QA(-) - PQA absorbance difference and triplet minus singlet spectra measured in PSII core complexes from Synechocystis PCC 6803 [Schlodder et al. Philos. Trans. R. Soc. London, Ser. B2008, 363, 1197]. We show that in the RC684 complexes, both PD1 and ChlD1 may serve as primary electron donors, leading to two different charge separation pathways. Resonant HB spectra cannot distinguish the CS times corresponding to different paths, but it is likely that the zero-phonon holes (ZPHs) observed in the 680-685 nm region (corresponding to CS times of ∼1.4-4.4 ps) reveal the ChlD1 pathway; conversely, the observation of charge-transfer (CT) state(s) in RC684 (in the 686-695 nm range) and the absence of ZPHs at λB > 685 nm likely stem from the PD1 pathway, for which CS could be faster than 1 ps. This is consistent with the finding of Krausz et al. [Photochem. Photobiol. Sci.2005, 4, 744] that CS in intact PSII core complexes can be initiated at low temperatures with fairly long-wavelength excitation. The lack of a clear shift of HB spectra as a function of excitation wavelength within the red-tail of the absorption (i.e., 686-695 nm) and the absence of ZPHs suggest that the lowest-energy CT state is largely homogeneously broadened. On the other hand, in usually studied destabilized RCs, that is, RC680, for which CT states have never been experimentally observed, ChlD1 is the most likely electron donor.

Coherent Detection of Electron Dephasing (2010)

We show that an Aharonov-Bohm ring with asymmetric electron injection can act as a coherent detector of electron dephasing. The presence of a dephasing source in one of the two arms of a moderately-to-highly asymmetric ring changes the response of the system from total reflection to complete transmission while preserving the coherence of the electrons propagating from the ring, even for strong dephasing. We interpret this phenomenon as an implementation of an interaction-free measurement.
Multiple Arousal Theory and Daily-Life Electrodermal Activity Asymmetry (2015)

Using “big data” from sensors worn continuously outside the lab, researchers have observed patterns of objective physiology that challenge some of the long-standing theoretical concepts of emotion and its measurement. One challenge is that emotional arousal, when measured as sympathetic nervous system activation through electrodermal activity, can sometimes differ significantly across the two halves of the upper body. We show that traditional measures on only one side may lead to misjudgment of arousal. This article presents daily life and controlled study data, as well as existing evidence from neuroscience, supporting the influence of multiple emotional substrates in the brain causing innervation on different sides of the body. We describe how a theory of multiple arousals explains the asymmetric EDA findings.
The tao of parallelism in algorithms (2011)

For more than thirty years, the parallel programming community has used the dependence graph as the main abstraction for reasoning about and exploiting parallelism in "regular" algorithms that use dense arrays, such as finite-differences and FFTs. In this paper, we argue that the dependence graph is not a suitable abstraction for algorithms in new application areas like machine learning and network analysis in which the key data structures are "irregular" data structures like graphs, trees, and sets.
The value of routine follow-up after treatment for head and neck cancer. A National Survey from DAHANCA (2013)

Only few relapses are found in asymptomatic patients at routine follow-up, with one silent recurrence detected per 99 visits. However, head and neck cancer survivors have a substantial need for management of sequelae. In this context, a centralized routine follow-up may still be worthwhile.

A Methodology for the Robust Estimation of the Radiation Pattern of Acoustic Sources (2019)

We propose a novel methodology for estimating the radiation pattern of acoustic sources, which is general enough as to be suitable for a wide variety of sources without the need of anechoic conditions of operation. Multiple plenacoustic cameras (which can be thought of as arrays of acoustic cameras) scan the source while keeping reflections and interferers at bay through deconvolution and windowing of the measured response. In the case of a moving source (e.g. a musical instrument while it is being played), the plenacoustic cameras are also used for tracking the position of the source. As for its orientation, we propose practical solutions for tracking that as well, whenever such information is not known in advance. Two experiments are conducted in order to validate the proposed solution. The former focuses on a commercial loudspeaker cabinet, whose radiation pattern is known in advance and can be used as groundtruth. The latter concerns violins, which exhibit an extremely rich and hard to predict acoustic behavior, due to their inherent structural and constructional complexity. Our method allows us to capture the radiation pattern of the instrument while it is being played, thus returning data corresponding to the natural timbre of the instrument, including the unavoidable acoustic shadow of the violinist's head. Experimental results confirm a relevant improvement in accuracy and robustness afforded by the adoption of dynamic plenacoustic solutions with respect to state-of-the-art techniques.

Gasoline Evaporative Emissions - Ethanol Effects on Vapor Control Canister Sorbent Performance (1995)

&lt;div class="htmlview paragraph"&gt;Tests were performed at the University of North Dakota Energy &amp;amp; Environmental Research Center (EERC) to compare the evaporation rate of 10 volume percent ethanol-blended gasoline (E10) with the evaporation rate of its base gasoline. Averaged results of the tests demonstrated that at 70°F (21.1 °C), the E10 fuel lost more total weight to evaporation than its base fuel, but less gasoline. The increased weight was due to ethanol, which was present in the E10 evaporative emissions at concentrations of about 13 weight percent. Subsequently, a test system was designed to investigate how the presence of ethanol in the evaporative emission affects the fuel evaporation canister sorbent performance. The system is equipped with a Fourier transform infrared spectrometer (FT-IR) to monitor sorbent breakthrough emission concentrations and compound types. Preliminary data obtained using sorbent from commercial canisters have shown that ethanol vapor breakthrough occurs significantly later than gasoline hydrocarbon vapor breakthrough.&lt;/div&gt;
In vitro aerosol delivery by vibrating mesh nebulizer (VMN) and pressurized metered dose inhaler (pMDI) using spacers in comparison with T adapters in mechanical ventilation. (2020)

<i>In vitro</i> performance of spacers were evaluated in comparison with T adapters in adult and paediatric mechanical ventilation models. With the ventilator set in volume controlled (VC) mode with adult breathing parameters, aerosol delivery by pMDI (Ventolin, GSK) was compared when using a spacer (CombiHaler<sup>®</sup>, Laboratoire optimHal-ProtecSom; Aerochamber MV<sup>®</sup>, AeroVent<sup>®</sup>&nbsp;and Aerochamber Mini<sup>®</sup>, Trudell Medical) instead of a T adapter (Intersurgical). Aerosol delivery by nebulization was compared when using a spacer instead of a T adapter (Aeroneb Solo<sup>®</sup> T piece, Aerogen).With the ventilator set in VC mode with peadiatric breathing parameters (corresponding to a child of 15kg weight), aerosol delivery by pMDI was compared when using a spacer (MinimHal<sup>®</sup>, Laboratoire OptimHal-ProtecSom) instead of a MDI adapter (Intersurgical) and aerosol delivery by nebulization was compared when using a spacer (MinimHal<sup>®</sup>) instead of a T adapter (Aeroneb Solo<sup>®</sup> peadiatric T piece). Using the adult model, Aerosol delivery by nebulization increased when using the spacer (42.75&nbsp;± 4.48 % vs 35.26&nbsp;± 7.44 %). Aerosol delivery by pMDI increased up to two or three-fold when using the spacer instead of an MDI adapter.Using the peadiatric model, aerosol delivery by nebulization was higher with the spacer than with the T&nbsp;piece (23.84&nbsp;± 7.72 % 15.06&nbsp;± 4.18 %). Aerosol delivery by pMDI increased by up to three-fold when using the spacer in comparison to the T adapter (9.45&nbsp;± 2.27 % vs 2.94&nbsp;± 0.34%). In this <i>in vitro</i> study, using a spacer instead of a T adapter with both a pMDI and a VMN increased drug delivery.
磁場-流体-機構連成解析と実験計画法を用いた形状最適化 (2021)

This paper presents the design optimization result of anchor shape with design of experiments (DOE) and magnetic-fluid-system co-simulation technology for designing a quieter high-pressure pump. Since the impact noise level increases with increasing valve impingement velocity, the objective of design optimization is to reduce the valve impingement velocity. In this study, we executed the DOE to simulate the anchor/core impingement velocity with oblique model and four design parameters. In addition, we also compared the impingement velocity results between which obtained by DOE and which obtained by original shape, evaluated the four design parameters with factor effect diagram and obtained following results. 1)The anchor impingement velocity which obtained by on two of nine models is slower than the original shape and. 2) The flat surface length(l2) of the anchor mostly affected the fluid force acting on the anchor in the oblique model. The length also mostly affected the solenoid force acting on the core and the anchor-core impingement velocity.
The RWTH system for statistical translation of spoken dialogues (2001)

This paper gives an overview of our work on statistical machine translation of spoken dialogues, in particular in the framework of the VERBMOBIL project. The goal of the VERBMOBIL project is the translation of spoken dialogues in the domains of appointment scheduling and travel planning. Starting with the Bayes decision rule as in speech recognition, we show how the required probability distributions can be structured into three parts: the language model, the alignment model and the lexicon model. We describe the components of the system and report results on the VERBMOBIL task. The experience obtained in the VERBMOBIL project, in particular a large-scale end-to-end evaluation, showed that the statistical approach resulted in significantly lower error rates than three competing translation approaches: the sentence error rate was 29% in comparison with 52% to 62% for the other translation approaches.

Theoretical Analysis of the Temperature–Field Phase Diagrams of Perovskite-Type Ferroelectrics (2008)

The temperature–field phase diagrams are discussed within the Landau theory for perovskite-type ferroelectrics, which undergo successive transitions of first order. The sequences of the cubic–tetragonal–orthorhombic–rhombohedral phases and the cubic–rhombohedral–orthorhombic–tetragonal phases are considered, and the field is applied along the [100], [110], or [111] direction. The topology of the phase diagrams obtained are found to depend much on the degree of the anisotropy of the Landau potential functions in the order parameter space. When the free energy function is nearly isotropic, the critical end points associated with all the possible ferroelectric phases, stabilized successively with decreasing temperature, appear at a certain field and temperature. Only the one associated with the highest temperature ferroelectric phase does that at a fairly high field. It is pointed out that the critical end points experimentally observed in the relaxor ferroelectrics like Pb(Mg 1/3 Nb 2/3 )O 3 suggests that the transition in the relaxor, if any, must be of first order.
Brace treatment of Colles' fracture (1989)

Twenty patients with Colles' fractures were treated with a functional brace that allows wrist motion. The result was compared with a similar group of patients treated with a plaster cast. Dorsal displacement of the fracture was less and wrist function was better in the brace group. Swelling of the hand during the early stages was observed in the brace group; and because this may necessitate brace adjustment, increased medical supervision is necessary for this period.
Chondrogenic Differentiation of Human Embryonic Stem Cells: The Effect of the Micro-Environment (2006)

We have previously induced differentiation of embryonic stem cells (ESC) to specific phenotypes by manipulating the culture conditions, including the use of indirect co-culture. In this study, we hypothesized that co-culture with primary chondrocytes can induce human embryonic stem cells (hESC) to differentiate towards the chondrocyte lineage. Co-cultures of hESC and chondrocytes were established using well inserts, with control comprising hESC grown alone or with fibroblasts. After 28 days, after removal of the chondrocyte inserts, hESC differentiation was assessed, by morphology, immunocytochemistry, and reverse transcription polymerase chain reaction. hESC, co-cultured or grown alone, were also implanted into SCID mice on a poly-D, L-lactide scaffold, harvested 35 days later and assessed in the same way. hESC co-cultured with chondrocytes formed colonies and secreted extracellular matrix containing glycosaminoglycans (GAG). Quantitative assay showed increased synthesis of sulfated GAG in co-culture as compared with control hESC grown alone for the same period (p < 0.0001). In addition, co-cultured hESC expressed Sox 9 and collagen type II, unlike control hESC. Co-culture with fibroblasts did not induce chondrogenic differentiation. The implanted constructs with co-cultured hESC contained significantly more type II collagen (p < 0.01), type I collagen (p < 0.05), total collagen (p < 0.01), and GAG (p < 0.01) than those with hESC grown alone. Thus, we show for the first time differentiation of hESC to chondrocytes. Our results confirm the potential of the culture micro-environment to influence ESC differentiation and could provide the basis for future generation of chondrogenic cells for use in tissue repair and increase our understanding of the mechanisms that direct differentiation.
