Impedance and Radiation Measurement Methodology for Ultra Miniature Antennas (2014)

This paper presents new measurement methodologies for ultra-miniature antennas. A first one is dedicated to the impedance measurement and the second one to the radiation measurement. Both methods are detailed focusing on an ultra-compact antenna design at 2.4 GHz, whose electrical dimensions, including the ground plane, are λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> /25×λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> /25×λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> /62.5. Given the very small antenna size compared to the wavelength, measurements by means of conventional coaxial cable can affect the characterization results. The issues related to the use of a feeding coaxial cable in both simulation and prototype measurements are first discussed. Then, specific methods to deduce the isolated antenna properties are proposed. Both methodologies rely on the use of electromagnetic simulation to compensate perturbations introduced by the measuring device.
Digital dielectrophoretic levitation (1991)

In this article we describe a computer-controlled active feedback dielectrophoretic (DEP) levitator and its measurement capabilities for characterizing single particles and particle chains (20–500 μm in length). Edge detection using a linear array of photodiodes is employed and an adaptive controller updates the voltage required for stable levitation at a rate of 4.7 kHz. Rms voltage fluctuations are typically less than 0.2% of the levitation voltage. The most precise data to date for the effective dipole moment of conducting particle chains up to four in length are presented along with experimental measurements of the effective dipole moment of two particle chains of unequal size as tests of accuracy and precision of the apparatus.
Application of magnetic particle tracking velocimetry to quadrupole magnetic sorting of porcine pancreatic islets (2011)

Magnetic isolation is a promising method for separating and concentrating pancreatic islets of Langerhans for transplantation in Type 1 diabetes patients. We are developing a continuous magnetic islet sorter to overcome the restrictions of current purification methods that result in limited yield and viability. In Quadrupole Magnetic Sorting (QMS) islets are magnetized by infusing superparamagnetic microbeads into islets' vasculature via arteries that serve the pancreas. The performance of the islet sorter depends on the resulting speed of the islets in an applied magnetic field, a property known as magnetophoretic mobility. Essential to the design and successful operation of the QMS is a method to measure the magnetophoretic mobilities of magnetically infused islets. We have adapted a Magnetic Particle Tracking Velocimeter (MPTV) to measure the magnetophoretic mobility of particles up to 1,000 µm in diameter. Velocity measurements are performed in a well-characterized uniform magnetic energy gradient using video imaging followed by analysis of the video images with a computer algorithm that produces a histogram of absolute mobilities. MPTV was validated using magnetic agarose beads serving as islet surrogates and subjecting them to QMS. Mobility distributions of labeled porcine islets indicated that magnetized islets have sufficient mobility to be captured by the proposed sorting method, with this result confirmed in test isolations of magnetized islets.
Analysis of Prediction Intervals for Non-Intrusive Estimation of Speech Clarity Index (2016)

We present an analysis of prediction intervals for a non-intrusive method to estimate the clarity index (C50). The method employed to estimate C50 is a data driven approach that extracts multiple features from a reverberant speech signal which are then used to train a bidirectional long-short term memory model which maps the feature space into the target C50 value. The prediction intervals are derived from the standard deviation of the per-frame C50 estimates. This approach was shown to provide a coverage probability of 80%, i.e. 80% of times the ground truth lies between the estimated intervals, where the interval bounds are computed by using 5.6 times the standard deviation of the per-frame estimates. This accuracy is shown to be consistent with other noisy reverberant environments.
A Collective Case Screening of the Zeolites made in Japan for High Performance NH3-SCR of NOx (2017)

Abstract Zeolites demonstrating better SCR of NOx performance due to wide temperature activity, hydrothermal stability and N2 selectivity have been identified under a joint research initiative by the Research Association of Automotive Internal Combustion Engines (AICE), Japan. Based on the AICE’s standards, over 25 zeolites with different structures and pore dimensions were investigated and their SCR efficiency and durability have been compared. While the performances of the top contenders cannot be related to a single parameter, the results suggest that the SAR, Cu quality/quantity, pore dimensions, diffusivity and acidity play a combined role in deciding the SCR activity and selectivity.
EBSeq: an empirical Bayes hierarchical model for inference in RNA-seq experiments (2013)

Motivation: Messenger RNA expression is important in normal development and differentiation, as well as in manifestation of disease. RNA-seq experiments allow for the identification of differentially expressed (DE) genes and their corresponding isoforms on a genome-wide scale. However, statistical methods are required to ensure that accurate identifications are made. A number of methods exist for identifying DE genes, but far fewer are available for identifying DE isoforms. When isoform DE is of interest, investigators often apply gene-level (count-based) methods directly to estimates of isoform counts. Doing so is not recommended. In short, estimating isoform expression is relatively straightforward for some groups of isoforms, but more challenging for others. This results in estimation uncertainty that varies across isoform groups. Count-based methods were not designed to accommodate this varying uncertainty, and consequently, application of them for isoform inference results in reduced power for some classes of isoforms and increased false discoveries for others. Results: Taking advantage of the merits of empirical Bayesian methods, we have developed EBSeq for identifying DE isoforms in an RNA-seq experiment comparing two or more biological conditions. Results demonstrate substantially improved power and performance of EBSeq for identifying DE isoforms. EBSeq also proves to be a robust approach for identifying DE genes.

Lets Make A Story Measuring MR Child Engagement (2021)

We present the result of a pilot study measuring child engagement with the Lets Make A Story system, a novel mixed reality, MR, collaborative storytelling system designed for grandparents and grandchildren. We compare our MR experience against an equivalent paper story experience. The goal of our pilot was to test the system with actual child users and assess the goodness of using metrics of time, user generated story content and facial expression analysis as metrics of child engagement. We find that multiple confounding variables make these metrics problematic including attribution of engagement time, spontaneous non-story related conversation and having the childs full forward face continuously in view during the story. We present our platform and experiences and our finding that the strongest metric was user comments in the post-experiential interview.
Subnuclear cyclin D3 compartments and the coordinated regulation of proliferation and immunoglobulin variable gene repression (2012)

Proliferation in response to mitogenic stimuli is associated with induction of a cascade of regulatory events that facilitates transit past the G 1 /S checkpoint into cell cycle.At the apex of this cascade are the D-type cyclins, including cyclin D1, cyclin D2, and cyclin D3, which bind and activate cyclin-dependent kinases 4 and 6 (CDK4/6).Cyclin D-CDK4/6 complexes initiate phosphorylation of the retinoblastoma protein (Rb) family members (Rb, p107, and p130), resulting in derepression of E2f transcription factors, the induction of additional cell cycle genes and transition through the G 1 checkpoint into S phase (Ciemerych and Sicinski, 2005).Although this model was initially established through analyses of cell lines, gene targeting revealed that the ubiquitous D-type cyclins are required only in the hematopoietic lineages and a few specialized peripheral tissues (Kozar et al., 2004;Malumbres et al., 2004).Within the hematopoietic lineages, the D-type cyclins provide unique functions.For example, Ccnd2 and Ccnd3, but not Ccnd1, are transcribed and the corresponding proteins are readily detected in B cell progenitors; however, only cyclin D3 is required for early B cell development and for the proliferation of pro-B and pre-B cells (Cooper et al., 2006).

A Polyoxovanadate as an Advanced Electrode Material for Supercapacitors (2014)

Polyoxovanadate Na(6)V(10)O(28) is investigated for the first time as electrode material for supercapacitors (SCs). The electrochemical properties of Na(6)V(10)O(28) electrodes are studied in Li(+) -containing organic electrolyte (1 M LiClO(4) in propylene carbonate) by galvanostatic charge/discharge and cyclic voltammetry in a three-electrode configuration. Na(6)V(10)O(28) electrodes exhibit high specific capacitances of up to 354 F g(-1). An asymmetric SC with activated carbon as positive electrode and Na(6)V(10)O(28) as negative electrode is fabricated and exhibits a high energy density of 73 Wh kg(-1) with a power density of 312 W kg(-1), which successfully demonstrates that Na(6)V(10)O(28) is a promising electrode material for high-energy SC applications.

Incorporating Uncertainty Into Path Planning for Minimally Invasive Robotic Neurosurgery (2021)

New robotics devices can provide minimally invasive access to deep lesions in the brain through small openings in the skull, which can reduce infection risk and improve recovery times when compared to larger craniotomies. Several groups have introduced semi and fully automatic path planning tools to optimize lesion access while avoiding damage to critical structures along the path. These tools utilize preoperative imaging and intraoperative neuronavigation to plan and execute lesion access. However, several factors can introduce uncertainty into path planning, including segmentation, patient-to-image registration, brain shift during surgery, and mechanical uncertainty in the robotic device during path following. Most systems handle uncertainty by adding a ‘safety margin’ (typically 2–3 mm) around structures to be avoided or around the path. However, safety margins are somewhat arbitrary. We propose using more rigorous models of uncertainty during path planning. We explore two sources of uncertainty in path planning, namely segmentation uncertainty and uncertainty due to brain shift, propose a method for computing brain shift uncertainty, show how to combine these uncertainties into a single risk volume, and provide clinical motivation by presenting our approach in the context of a path planning system for robotic neurosurgery designed for treating mesial temporal lobe epilepsy.
Usability Assessment of a Cable-Driven Exoskeletal Robot for Hand Rehabilitation (2019)

<b>Study design:</b> Case series. <b>Background:</b> Robot-assisted rehabilitation mediated by exoskeletal devices is a popular topic of research. The biggest difficulty in the development of rehabilitation robots is the consideration of the clinical needs. This study investigated the usability of a novel cable-driven exoskeletal robot specifically designed for hand rehabilitation. <b>Methods:</b> The study consists of three steps, including prototype development, spasticity observation, and usability evaluation. First, we developed the prototype robot <i>DexoHand</i> to manipulate the patient's fingers based on the clinical needs and the cable-driven concept established in our previous work. Second, we applied <i>DexoHand</i> to patients with different levels of spasticity. Finally, we obtained the system usability scale (SUS) and assessed its usability. <b>Results:</b> Two healthy subjects were recruited in the pre-test, and 18 patients with stroke and four healthy subjects were recruited in the formal test for usability. The total SUS score obtained from the patients and healthy subjects was 94.77 ± 2.98 (<i>n</i> = 22), indicating an excellent level of usability. The satisfaction score was 4.74 ± 0.29 (<i>n</i> = 22), revealing high satisfaction with <i>DexoHand</i>. The tension profile measured by the cables showed the instantaneous force used to manipulate fingers among different muscle tone groups. <b>Conclusions:</b> <i>DexoHand</i> meets the clinical needs with excellent usability, satisfaction, and reliable tension force monitoring, yielding a feasible platform for robot-assisted hand rehabilitation.
Why has the number of scientific retractions increased? (2015)

Background:The number of retracted scientific publications has risen sharply, but it is unclear whether this reflects an increase in publication of flawed articles or an increase in the rate at which flawed articles are withdrawn. Methods and Findings:We examined the interval between publication and retraction for 2,047 retracted articles indexed in PubMed.Time-to-retraction (from publication of article to publication of retraction) averaged 32.91 months.Among 714 retracted articles published in or before 2002, retraction required 49.82 months; among 1,333 retracted articles published after 2002, retraction required 23.82 months (p,0.0001).This suggests that journals are retracting papers more quickly than in the past, although recent articles requiring retraction may not have been recognized yet.To test the hypothesis that time-to-retraction is shorter for articles that receive careful scrutiny, time-to-retraction was correlated with journal impact factor (IF). Time-to-retraction was significantly shorter for high-IF journals, but only ,1% of the variance in time-toretraction was explained by increased scrutiny.The first

Zinc–Air Batteries Catalyzed Using Co3O4 Nanorod-Supported N-Doped Entangled Graphene for Oxygen Reduction Reaction (2021)

The work reported here deals with the development of an efficient non-platinum electrocatalyst for electrochemical oxygen reduction reaction (ORR) through a sequential pathway involving hydrothermal treatment followed by freeze-drying to build the desired structural architecture of the catalyst. The designed catalyst (Co3O4/ nitrogen-doped entangled porous 3D graphene (NEGF)), which contains Co3O4 nanorods anchored on the surface of three-dimensional (3D)-structured N-doped graphene, was found to display higher ORR activity during single-electrode testing and demonstrate a Zn–air battery (ZAB) system. Under the hydrothermal treatment at 180 °C, in the presence of ammonia, nitrogen was doped into the carbon framework of graphene, which subsequently formed a self-assembled entangled 3D structure of graphene after freeze-drying. The hydrothermal treatment and freeze-drying processes were found to play vital roles in tuning the morphological and structural features of the catalyst. The doped nitrogen, apart from its favorable contribution toward ORR, helped facilitate efficient dispersion of oxide nanorods on graphene. Co3O4/NEGF displayed remarkable ORR activity in 0.1 M KOH solution, as evident from the 60 mV onset potential shift compared to the state-of-the-art Pt/C catalyst and the Tafel slope value of 74 mV dec–1 vs 68 mV dec–1 for Pt/C. The ZAB fabricated by employing Co3O4/NEGF as the cathode catalyst was found to be an efficient competitor for the system based on the Pt/C cathode. This high performance has been credited to the controlled interplay of the governing factors such as the interfacial interactions leading to the efficient dispersion of metal oxide nanorods, increased catalyst surface area, the cooperative effect arising from the defects present in the N-doped porous 3D graphene, and the synergetic interactions operating in the system.
Low-Temperature Growth of AlN Films on Magnetostrictive Foils for High-Magnetoelectric-Response Thin-Film Composites (2021)

This study reports a strong ME effect in thin-film composites consisting of nickel, iron, or cobalt foils and 550 nm thick AlN films grown by PE-ALD at a (low) temperature of 250 °C and ensuring isotropic and highly conformal coating profiles. The AlN film quality and the interface between the film and the foils are meticulously investigated by means of high-resolution transmission electron microscopy and the adhesion test. An interface (transition) layer of partially amorphous Al<sub><i>x</i></sub>O<sub><i>y</i></sub>/AlO<sub><i>x</i></sub>N<sub><i>y</i></sub> with thicknesses of 10 and 20 nm, corresponding to the films grown on Ni, Fe, and Co foils, is revealed. The AlN film is found to be composed of a mixture of amorphous and nanocrystalline grains at the interface. However, its crystallinity is improved as the film grew and shows a highly preferred (002) orientation. High self-biased ME coefficients (α<sub>ME</sub> at a zero-bias magnetic field) of 3.3, 2.7, and 3.1 V·cm<sup>-1</sup>·Oe<sup>-1</sup> are achieved at an off-resonance frequency of 46 Hz in AlN/Ni thin-film composites with different Ni foil thicknesses of 7.5, 15, and 30 μm, respectively. In addition, magnetoelectric measurements have also been carried out in composites made of 550 nm thick films grown on 12.5 μm thick Fe and 15 μm thick Co foils. The maximum magnetoelectric coefficients of AlN/Fe and AlN/Co composites are 0.32 and 0.12 V·cm<sup>-1</sup>·Oe<sup>-1</sup>, measured at 46 Hz at a bias magnetic field (<i>H</i><sub>dc</sub>) of 6 and 200 Oe, respectively. The difference of magnetoelectric transducing responses of each composite is discussed according to interface analysis. We report a maximum delivered power density of 75 nW/cm<sup>3</sup> for the AlN/Ni composite with a load resistance of 200 kΩ to address potential energy harvesting and electromagnetic sensor applications.

Towards establishing human body-on-a-chip systems (2022)

Body-on-a-chip (BoC) platforms are established from multiple organs-on-chips (OoCs) to recapitulate the interactions between different tissues. Recently, Vunjak-Novakovic and colleagues reported the creation of a BoC system comprising four fluidically linked OoCs. Herein, the major innovations in their BoC system are discussed, followed by our future perspectives on enhancing the physiological relevance and scalability of BoCs for applications in studying disease mechanisms, testing potential therapeutics, and developing personalized medicine.
Automating the pharmacy: implementing Cerner's Millenium Pharmnet System (2002)

Cerner's Health Network Architecture (HNA) Millenium Pharmnet System was recently implemented at Metro Health Systems of Cleveland. This cutting-edge pharmacy management system has only been installed, with limited functionality, at one site in Canada: this was the first time it was installed in an American medical institution as well as employing the billing capability of the software. In order for this software to be successful, the entire Cerner HNA Millenium system had to be designed, installed, and maintained properly. The HNA Millenium system includes four distinct pieces: the front-end PC applications, the Cerner executables that access the Oracle relational database, the Oracle relational database itself, and the OpenVMS operating system and disks. The system began handling live pharmacy orders (conversion) in November of 1999 and is currently fully operational.

Unravelling the Nature of the Intrinsic Complex Structure of Binary‐Phase Na‐Layered Oxides (2022)

The layered sodium transition metal oxide, NaTMO<sub>2</sub> (TM = transition metal), with a binary or ternary phases has displayed outstanding electrochemical performance as a new class of strategy cathode materials for sodium-ion batteries (SIBs). Herein, an in-depth phase analysis of developed Na<sub>1-x</sub> TMO<sub>2</sub> cathode materials, Na<sub>0.76</sub> Ni<sub>0.20</sub> Fe<sub>0.40</sub> Mn<sub>0.40</sub> O<sub>2</sub> with P2- and O3-type phases (NFMO-P2/O3) is offered. Structural visualization on an atomic scale is also provided and the following findings are unveiled: i) the existence of a mixed-phase intergrowth layer distribution and unequal distribution of P2 and O3 phases along two different crystal plane indices and ii) a complete reversible charge/discharge process for the initial two cycles that displays a simple phase transformation, which is unprecedented. Moreover, first-principles calculations support the evidence of the formation of a binary NFMO-P2/O3 compound, over the proposed hypothetical monophasic structures (O3, P3, O'3, and P2 phases). As a result, the synergetic effect of the simultaneous existence of P- and O-type phases with their unique structures allows an extraordinary level of capacity retention in a wide range of voltage (1.5-4.5 V). It is believed that the insightful understanding of the proposed materials can introduce new perspectives for the development of high-voltage cathode materials for SIBs.
