Model-based registration for assessment of spinal deformities in idiopathic scoliosis (2013)

Detailed analysis of spinal deformity is important within orthopaedic healthcare, in particular for assessment of idiopathic scoliosis. This paper addresses this challenge by proposing an image analysis method, capable of providing a full three-dimensional spine characterization. The proposed method is based on the registration of a highly detailed spine model to image data from computed tomography. The registration process provides an accurate segmentation of each individual vertebra and the ability to derive various measures describing the spinal deformity. The derived measures are estimated from landmarks attached to the spine model and transferred to the patient data according to the registration result. Evaluation of the method provides an average point-to-surface error of 0.9 mm ± 0.9 (comparing segmentations), and an average target registration error of 2.3 mm ± 1.7 (comparing landmarks). Comparing automatic and manual measurements of axial vertebral rotation provides a mean absolute difference of 2.5° ± 1.8, which is on a par with other computerized methods for assessing axial vertebral rotation. A significant advantage of our method, compared to other computerized methods for rotational measurements, is that it does not rely on vertebral symmetry for computing the rotational measures. The proposed method is fully automatic and computationally efficient, only requiring three to four minutes to process an entire image volume covering vertebrae L5 to T1. Given the use of landmarks, the method can be readily adapted to estimate other measures describing a spinal deformity by changing the set of employed landmarks. In addition, the method has the potential to be utilized for accurate segmentations of the vertebrae in routine computed tomography examinations, given the relatively low point-to-surface error.
A Data-Driven Method for Predicting Capacity Degradation of Rechargeable Batteries (2019)

Rechargeable batteries supply numerous devices with electric power and are critical part in a variety of applications. An accurate monitoring and prediction of capacity degradation is directly related to making timely decision as to when a battery should be replaced, so that power disruption of the system it supplies power to is avoided. We propose a methodology for predicting capacity of a battery over future time horizon. The proposed method is based on training data consisting of occasional measurements, taken under the same conditions, of capacity and charge/discharge voltage/current of a certain number of batteries sharing the same chemistry and manufacturer, that otherwise undergo different usage patterns. In the operational/online stage, capacity degradation over future time horizon of a test battery cell of unknown state of health and previous usage pattern is predicted based on its capacity and voltage/current measurements over one charge/discharge cycle and the training dataset. The experimental validation reveals that the proposed method predicts capacity of a test battery cell over prediction time horizon of few hundred days of battery's operation with relative prediction error below 1%.

Latching shock sensors for health monitoring and quality control (2005)

The ability to monitor shock level is important for missile health monitoring to predict the performance after storage and eliminate potentially damaged units. Shock sensing is also of interest for monitoring the handling conditions of fragile shipments and providing a measure of unit-level quality control not currently available. A MEMS bi-polar single axis latching shock sensor has been developed with the goal of monitoring shock events and with the potential to "wake up" other sensing circuitry after a shock event occurs. An important feature of the sensor is that power is only consumed when a shock event occurs, making it suitable for long-term remote monitoring applications. The shock sensor has been designed, fabricated and characterized. High volume, low unit cost production will be enabled through the use of standard MEMS fabrication technologies such as DRIE and SOI wafer processing.
Streaming Layered Encoded Video Using Peers (2005)

Peer-to-peer video streaming has emerged as an important means to transport stored video. The peers are less costly and more scalable than an infrastructure-based video streaming network which deploys a dedicated set of servers to store and distribute videos to clients. In this paper, we investigate streaming layered encoded video using peers. Each video is encoded into hierarchical layers which are stored on different peers. The system serves a client request by streaming multiple layers of the requested video from separate peers. The system provides unequal error protection for different layers by varying the number of copies stored for each layer according to its importance. We evaluate the performance of our proposed system with different copy number allocation schemes through extensive simulations. Finally, we compare the performance of layered coding with multiple description coding.
Parathymosin alpha: a peptide from rat tissues with structural homology to prothymosin alpha. (1985)

A peptide, parathymosin alpha, containing approximately equal to 105 amino acid residues, has been isolated from rat thymus, and the sequence of the first 30 residues at the NH2 terminus has been determined. In this region, it shows 43% structural identity with thymosin alpha 1 and prothymosin alpha. The common sequences do not include residues 2-9, which accounts for the poor reactivity of parathymosin alpha with an antibody directed against this epitope in thymosin alpha 1. Parathymosin alpha appears to modulate the action of prothymosin alpha in protecting sensitive strains of mice against opportunistic infection with Candida albicans.
Magnonic Holographic Memory: From Proposal to Device (2015)

In this paper, we present recent developments in magnonic holographic memory devices exploiting spin waves for information transfer. The devices comprise a magnetic matrix and spin wave-generating/detecting elements placed on the edges of the waveguides. The matrix consists of a grid of magnetic waveguides connected via cross junctions. Magnetic memory elements are incorporated within the junction, while the read-in and read-out are accomplished by the spin waves propagating through the waveguides. We present the experimental data on spin-wave propagation through NiFe and yttrium iron garnet Y <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> Fe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> (FeO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> ) <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> (YIG) magnetic crosses. The obtained experimental data show prominent spin-wave signal modulation (up to 20 dB for NiFe and 35 dB for YIG) by the external magnetic field, where both the strength and the direction of the magnetic field define the transport between the cross arms. We also present the experimental data showing parallel read-out of two magnetic memory elements via spin-wave interference. The recognition between the four possible memory states is achieved via proper adjustment of the phases of the interfering spin waves. All experiments are done at room temperature. Magnonic holographic devices aim to combine the advantages of magnetic data storage with wave-based information transfer. We present estimates on the spin-wave holographic devices performance, including power consumption and functional throughput. According to the estimates, the magnonic holographic devices may provide data processing rates higher than 1 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">18</sup> b/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /s while consuming 0.15 mW.

Abstract 17025: Stable in vivo Ventricular Pacing Created by Tbx18-induced Pacemaker Cells Upon Inhibition of Epithelial-to-mesenchymal Transformation in an Ambulatory Rat Model of Complete Atrioventricular Block (2017)

Introduction: We have previously demonstrated conversion of ventricular cardiomyocytes to induce pacemaker cells (iPMs) by TBX18. However, the iPMs’ automaticity waned over time due to epithelial-to-mesenchymal transformation (EMT)-mediated cell detachment, collaterally activated by TBX18. We hypothesized that inhibitions of EMT with direct myocardial gene transfer of TBX18 can induce stable biological pacing in a rat model of complete atrioventricular block (CAVB). Methods: A rat model of CAVB was created by ablating the AV node area with a high-frequency electrosurgical generator. Upon CAVB, adenoviral gene transfer of human TBX18 was performed to the LV apex. In another group of TBX18-injected rats, an osmotic pump was implanted for peritoneal release of an inhibitor of EMT, A83. Control animals were implanted with an A83-osmotic pump, but injected with a GFP adenovirus. Animal were followed for 3 wks by telemetry and weekly ECG. Results: Immediately upon CAVB, control rats’ heart rate dropped from 352±40 to 102±38 bpm (n=15). The CAVB rats were sustained by slow junctional rhythm which persisted from wk1 (132±19) through wk4 (134±22). TBX18-injected rats’ mean ventricular rate increased from 165±46 (d1) to 186±35 bpm at wk1 but began wavering, 179±46 at wk2 and 167±44 at wk3. In contrast, TBX18-injected rats with EMT inhibition exhibited stable biological pacing at rates significantly higher than control and TBX18-only rats; 171±41 (d1), 157±35 (wk1), 176±54 (wk2), and 231±33 (wk3). TBX18-only group showed non-sustained ectopic beats that often competed with junctional escape beats. In contrast, TBX18-injected rats with EMT inhibition demonstrated highly-organized, sustained ventricular beats that often approach the sinus rate. With EMT inhibition, the TBX18-transduced myocardium was restricted to the injection site, similar to the GFP. Without EMT inhibition, however, TBX18-transduced myocardium appeared to spread away from the injection site. Conclusions: Stable, TBX18-mediated biological pacing in vivo can be achieved by simultaneous inhibition of EMT. The iPMs, with suppressed EMT, retain cell-cell coupling and synchronous pacing, and may allow the iPMs to better overcome the source-to-sink mismatch in ventricular myocardium.
