Fractional derivative models for ultrasonic characterization of polymer and breast tissue viscoelasticity (2009)

The viscoelastic response of hydropolymers, which include glandular breast tissues, may be accurately characterized for some applications with as few as 3 rheological parameters by applying the Kelvin-Voigt fractional derivative (KVFD) modeling approach. We describe a technique for ultrasonic imaging of KVFD parameters in media undergoing unconfined, quasi-static, uniaxial compression. We analyze the KVFD parameter values in simulated and experimental echo data acquired from phantoms and show that the KVFD parameters may concisely characterize the viscoelastic properties of hydropolymers. We then interpret the KVFD parameter values for normal and cancerous breast tissues and hypothesize that this modeling approach may ultimately be applied to tumor differentiation.

Detection of Hypoglycemia With the GlucoWatch Biographer (2001)

The results show that as the low-glucose alert level of the biographer is increased, the number of true positive alerts (alarm sounds and blood glucose < or = 3.9 mmol/l) and false positive alerts (alarm sounds but blood glucose >3.9 mmol/l) increased. When analyzed as a function of varying low-glucose alert levels, the results show receiver operator characteristic curves consistent with a highly useful diagnostic tool. Setting the alert level from 1.1 to 1.7 mmol/l above the level of concern is likely to optimize the trade-off between true positives and false positives for each user. When the same blood glucose data are analyzed for typical monitoring practices (two or four measurements per day), the results show that fewer hypoglycemic events are detected than those detected with the biographer.
[Facioscapulohumeral muscular dystrophy (FSHD)]. (1997)

Facioscapulohumeral muscular dystrophy (FSHD; MIM 158900) is one of the major forms of muscular dystrophy, and is inherited in an autosomal dominant fashion. In most patients with FSHD, deletion of 3.3 kb tandemly repeated units within the EcoRI fragment, as detected by p13E-11 (D4F104S1) on chromosome 4q35, is associated with the disease (FSHD1A or 4q35-FSHD). Rare (< 5%) 4q35-unlinked FSHD (FSHD1B) is also known, and therefore genetic heterogeneity exists among FSHD. Recent studies based on the distinction of 4q35 EcoRI fragments from those of 10q26 improved the reliability of molecular diagnosis of the disease (> 95% accuracy). However, gene for FSHD1A has not been identified yet. Identification of the FSHD gene and characterization of the gene product are waited on tiptoe with expectation.
Investigations into the operation of a microstrip-fed uniplanar quasi-Yagi antenna (2000)

A parameter investigation into the broadband operation of a microstrip-fed uniplanar quasi-Yagi antenna using a full-wave electromagnetic field analysis is performed. In this study parameters that mostly affect this antenna's design frequency and operational bandwidth are identified. For experimental verification a Ku-band prototype antenna is fabricated and its return loss and radiation patterns are presented.
Identification of Stretch Reflex Dynamics from Closed-Loop Data**Supported by the Natural Sciences and Engineering Research Council of Canada through grant NSERC-RPGIN 238939-2010. (2015)

The torque and angle data used to identify models of limb impedance are usually generated under closed-loop conditions. In many cases, the joint position is controlled using a powerful position servo, so that the joint interacts with a very stiff environment. Under these conditions, the data may be treated as if they had been obtained in open-loop conditions. When experiments are performed under compliant conditions, the effects of feedback can no longer be ignored. A closed-loop identification algorithm which identifies a finite impulse response model of joint admittance has previously been developed, and used to estimate the admittance of the elbow joint under a variety of experimental conditions. The approach was based on prediction error minimization, and identified the FIR system model with an ARMA noise model. The experimental input was chosen to minimize the effects of reexes, so that the system would be very nearly linear. Standard correlation based tests were used to validate the resulting models. In this paper, we use two simulation models of the human ankle joint together with a typical experimental apparatus. The actuator was configured so that it could create both stiff and compliant environments, which allowed for the simulation of a broad range of joint dynamics experiments. In one case, a linear model was used, while the other included a nonlinear model of the stretch reex. Data from both simulations was processed using the closed-loop linear identification methods described above. Significant differences were noted between the models obtained from the linear and nonlinear simulations. Thus, the presence of the reex pathway biased the linear identification. However, the standard correlation based model tests suggested that the linear model structures were appropriate in both cases. The residuals appeared to be white noise, and not causally correlated with the input torque. High-order correlation based tests, normally used in the validation of parametric nonlinear models, revealed the presence of unmodeled nonlinearities in the system. This analysis is then applied to experimental data from a study on elbow compliance.

Entanglement-Induced Two-Photon Transparency (1997)

The rate of absorption of entangled photon pairs is linear in the photon-flux density. We demonstrate that the two-photon absorption cross section is a nonmonotonic function of the entanglement time; it vanishes for certain energy-level configurations and values of the entanglement time. This entanglement-induced two-photon transparency arises from the coherent summation of transition-amplitude contributions over the finite entanglement time. As an example, the entangled two-photon cross section for the $1S\ensuremath{-}2S$ electronic transition in atomic hydrogen is obtained.

Influenza virus enhances exposure of CEACAM6 receptor in intestinal cells. (2015)

&lt;p&gt;Caco-2 cells were infected with PR8 at 0.2 and 0.8 MOI and maintained for 4, 6 and 24 hrs at 37°C. Cells were then fixed and samples were incubated with anti-HA to assess viral infection or anti-CEACAM6 Abs to detect antigen expression in PR8 infected cell and in the control cell (Mock-I), (see &lt;a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117005#sec002" target="_blank"&gt;Methods&lt;/a&gt;).

Characterization of the complex 7q21.3 rearrangement in a patient with bilateral split‐foot malformation and hearing loss (2009)

We report on complex rearrangements of the 7q21.3 region in a female patient with bilateral split-foot malformation and hearing loss. G-banding karyotype was 46,XX,t(7;15)(q21;q15),t(9;14)(q21;q11.2)dn. By fluorescence, in situ hybridization (FISH), Southern hybridization, and inverse PCR, the 7q21.3 translocation breakpoint was determined at the nucleotide level. The breakpoint did not disrupt any genes, but was mapped to 38-kb telomeric to the DSS1 gene, and 258- and 272-kb centromeric to the DLX6 and DLX5 genes, respectively. It remains possible that the translocation would disrupt the interaction between these genes and their regulatory elements. Interestingly, microarray analysis also revealed an interstitial deletion close to (but not continuous to) the 7q21.3 breakpoint, indicating complex rearrangements within the split-hand/foot malformation 1 (SHFM1) locus in this patient. Furthermore, a 4.6-Mb deletion at 15q21.1-q21.2 adjacent to the 15q15 breakpoint was also identified. Cloning of the deletion junction at 7q21.3 revealed that the 0.8-Mb deletion was located 750-kb telomeric to the translocation breakpoint, encompassing TAC1, ASNS, OCM, and a part of LMTK2. Because TAC1, ASNS, and OCM genes were located on the reported copy number variation regions, it was less likely that the three genes were related to the split-foot malformation. LMTK2 appeared to be a potential candidate gene for SHFM1, but no LMTK2 mutations were found in 29 individuals with SHFM. Further LMTK2 analysis of SHFM patients together with hearing loss is warranted.
Cyclic Fatigue and Creep Resistance Testing of the PUMA SystemTM (2022)

Category: Ankle; Basic Sciences/Biologics; Trauma Introduction/Purpose: The PUMA System (Panther Orthopedics, Sunnyvale, CA) is an FDA cleared. superelastic, nitinol based fixation device for the ankle syndesmosis which provides stabilization without over-compression or loosening due to creep from cyclic loading. Objective The objective of this study was to test resistance to lengthening (creep) of the PUMA System in cyclic fatigue testing. Methods: Five PUMA System devices, each having a nitinol Body consisting of six layers, were cycle-tested between 20/40 pounds per cubic foot (lb/ft 3 ) polyurethane foam Bone Blocks (Figure 1).[1] The PUMA System devices were set up with an initial device Active Length of approximately 66 millimeters (mm) between their polyether ether ketone (PEEK) Anchor buttons. All devices were tightened to a minimum of 11.1 Newtons (2.5 pounds force) and cycled at 5 cycles per second (5 Hz) for 4500 cycles to 2.4 mm displacement. Device Active Length was recorded pre- and post-testing. Devices were visually inspected for any break in the 30 nitinol layers. [1] ASTM F1839: Standard Specification for Rigid Polyurethane Foam for Use as a Standard Material for Testing Orthopedic Devices and Instruments. Results: None of the 30 layers incorporated in the 5 PUMA System TM device Bodies failed due to cyclic fatigue. Also, there was little-to-no difference between pre- and post-testing Active Length ( Figure 2 ). More specifically an average increase of only 0.2% in length with a with a Standard Deviation of 0.16% evidences no significant creep (Table 1). Conclusion: The PUMA System TM allows for ankle syndesmosis repair with an implant that experiences no significant creep as demonstrated in cyclic-fatigue testing under challenging displacement cycle testing.
Twist, tilt and stretch: From isometric Kelvin cells to anisotropic cellular materials (2020)

Simple geometric distortions applied to the isometric Kelvin cell structures, (the tetrakaidecahedron), are shown to result in equivalent materials with anisotropic Hooke's tensors. The equivalent material models are estimated using a recently published inversion method where the 21 independent elastic constants of the Hooke's tensor are identified. In these cell geometries, some of the faces of the Kelvin cell have been twisted and/or tilted. Numerical experiments suggest that the equivalent material models of the distorted cells exhibit variations in compression, shearing, shear-compression and shear-shear coupling moduli, which are shown to be continuous functions of the degree of twist and tilt applied. When twist and tilt are combined, it is demonstrated that full anisotropy in the elastic properties may be generated. A rotational symmetry without symmetry planes, but having either a tetragonal or a monoclinic elastic symmetry is discussed. Four cell geometries, one isometric and three distorted, were manufactured using masked stereolithography 3D printing technology and measured in a laboratory compression set-up. Results from numerical simulations are compared to the experimental in terms of the compressive modulus.
A conserved proline residue in Dothideomycete Avr4 effector proteins is required to trigger a Cf‐4‐dependent hypersensitive response (2015)

CfAvr4, a chitin-binding effector protein produced by the Dothideomycete tomato pathogen Cladosporium fulvum, protects the cell wall of this fungus against hydrolysis by secreted host chitinases during infection. However, in the presence of the Cf-4 immune receptor of tomato, CfAvr4 triggers a hypersensitive response (HR), which renders the pathogen avirulent. Recently, several orthologues of CfAvr4 have been identified from phylogenetically closely related species of Dothideomycete fungi. Of these, DsAvr4 from Dothistroma septosporum also triggers a Cf-4-dependent HR, but CaAvr4 and CbAvr4 from Cercospora apii and Cercospora beticola, respectively, do not. All, however, bind chitin. To identify the region(s) and specific amino acid residue(s) of CfAvr4 and DsAvr4 required to trigger a Cf-4-dependent HR, chimeric and mutant proteins, in which specific protein regions or single amino acid residues, respectively, were exchanged between CfAvr4 and CaAvr4 or DsAvr4 and CbAvr4, were tested for their ability to trigger an HR in Nicotiana benthamiana plants transgenic for the Cf-4 immune receptor gene. Based on this approach, a single region common to CfAvr4 and DsAvr4 was determined to carry a conserved proline residue necessary for the elicitation of this HR. In support of this result, a Cf-4-dependent HR was triggered by mutant CaAvr4 and CbAvr4 proteins carrying an arginine-to-proline substitution at this position. This study provides the first step in deciphering how Avr4 orthologues from different Dothideomycete fungi trigger a Cf-4-dependent HR.
Adaptive Multi-Sensor Information Fusion For Autonomous Urban Air Mobility Operations (2021)

View Video Presentation: https://doi.org/10.2514/6.2021-1115.vid An adaptive method is developed to iteratively fuse the information provided by multiple sensors to enable autonomous urban air mobility type operations. First, noisy and bias corrupted IMU readings are processed as soon as they arrive using kinematic equations represented in the vehicle's body frame. To correct the systems drift resulting from the integration, an information content measure is introduced to decide on the environment. For the cluttered environment the information provided by environmental sensors is counted as reliable and the drift correction as accurate. For the open space, the GPS data is counted as reliable, and the drift correction is done based on the GPS readings. The measurement noise effects are minimize using Iterated Extended Kalman Filter framework. The algorithm is implemented in the in-house developed FlightDeckz simulation environment using an IMU model, simulated video recorded from a camera mounted on the vehicle (for the purpose of this study, outside scenery was generated with XPlane), which flies in an urban environment, and GPS data generated from the environment's digital map.
Acute-onset chronic inflammatory demyelinating polyneuropathy after COVID-19 infection and subsequent ChAdOx1 nCoV-19 vaccination (2021)

SARS-COV-2 predominantly results in a respiratory illness. However, it has also been associated with a wide range of neurological disorders including a broad range of immune neuropathies. These immune neuropathies associated with SARS-COV2 infection include Guillain-Barré syndrome (GBS), recurrent GBS and exacerbation of pre-existing chronic inflammatory demyelinating polyneuropathy (CIDP). We describe a case with acute-onset CIDP presenting with three relapses of demyelinating polyradiculoneuropathy, the third relapse occurring in the 8 week of illness following a previous COVID-19 infection and a recent COVID-19 vaccination with ChAdOx1 nCoV-19 and high COVID-19 antibody level. In our knowledge, this is the ever reported case of acute-onset CIDP associated with COVID-19 vaccine and high COVID-19 antibody level.
A framework for ATM via satellite (2002)

This paper describes an ATM-based satellite network. The ATM requirements and the basic design of the network are outlined. In particular, a simple MAC layer is proposed in which ATM service classes are mapped onto MF-TDMA uplink access methods. This paper shows that different qualities-of-service can be provided by using a combination of fixed (for signaling), demand and free assignment (for data).
Hot carrier effects in trench-based integrated power transistors (2009)

This paper reports for the first time on anomalous hot carrier effects observed in vertically integrated trench-based (TB-MOS) power transistors. The avalanche current reaches a maximum at intermediate drain voltage, and decreases for increasing drain voltage. The hot carrier lifetime of the transistors yields a minimum at intermediate drain voltage, and not at the maximum drain voltage. Charge pumping experiments enable to locate the degradation in the TB-MOS. A degradation model is proposed.
Myositis: Immunologic Contributions to Understanding Cause, Pathogenesis, and Therapy (1995)

The myositis syndromes, the most common forms of which are polymyositis and dermatomyositis, are defined by idiopathic chronic inflammation in skeletal muscle. Although initially described more than a century ago, these diseases are so rare and heterogeneous that we have only a limited understanding of their causes and treatment. Recently, autoimmune responses to nuclear and cytoplasmic autoantigens that are unique to patients with myositis, the myositis-specific autoantibodies, have proved clinically useful in helping predict signs and symptoms of myositis, immunogenetics, responses to therapy, and prognosis. We summarize this new information on the variety and nature of these autoantibodies, their target epitopes, and their possible use in identifying causes, pathogenetic mechanisms, and better therapies for these increasingly recognized disorders.
Gene Profiling Changes in Cytoskeletal Proteins During Clinical Recovery After Left Ventricular–Assist Device Support (2005)

Discovering cellular protein‐protein interactions: Technological strategies and opportunities (2018)

The analysis of protein interaction networks is one of the key challenges in the study of biology. It connects genotypes to phenotypes, and disruption often leads to diseases. Hence, many technologies have been developed to study protein-protein interactions (PPIs) in a cellular context. The expansion of the PPI technology toolbox however complicates the selection of optimal approaches for diverse biological questions. This review gives an overview of the binary and co-complex technologies, with the former evaluating the interaction of two co-expressed genetically tagged proteins, and the latter only needing the expression of a single tagged protein or no tagged proteins at all. Mass spectrometry is crucial for some binary and all co-complex technologies. After the detailed description of the different technologies, the review compares their unique specifications, advantages, disadvantages, and applicability, while highlighting opportunities for further advancements.

Bandwidth and information in the design and analysis of polarimeters (2015)

Polarimeters operate by making polarization-dependent alterations in the intensity of the optical ﬁeld. Modulated polarimeters introduce controlled ﬂuctuations as a function of time, spatial position, wavelength, angle of incidence, or any other independent variable. These ﬂuctuations create channels in frequency space that can be used to carry the polarimetric information. Since polarimeters are then inherently multiplexed information systems, issues of noise, bandwidth, channel cross-talk, and system conditioning become immediately important. This paper reviews much of the work over the past two decades on polarimeter design, and presents some of the most recent work on hybrid and non-periodic modulation schemes that hold out potential for maximizing system bandwidth.
