Linearization through Narrowband Feedback: Problems and Solutions (2014)

An adaptive predistorter is an effective technique to compensate for the nonlinear distortion of power amplifiers. To enable broadband communications, the bandwidth of communication systems has been continuously increased. With these increases in bandwidth, frequency distortions due to limitations in the bandwidth of the predistorter's building blocks can no longer be ignored. Such distortions are important factors that deteriorate a predistorter's linearization performance. Two main problems directly related with linearization through the narrow feedback path have been the subject of investigation in this study: predistorter's performances degradation due to feedback signal bandwidth restrictions and selection of appropriate predistorter architecture suitable for the linearization through narrowband feedback path. Also, in this study we propose a new predistorter architecture based on the inverse modeling for the power amplifier model that is robust against feedback signal bandwidth restrictions. Simulation and experimental results show that with the proposed predistorter architecture, the required feedback signal bandwidth can be reduced approximately to 1.15 times of the transmitting signal bandwidth with minimal degradations in the linearization performances.
A Tribute to Robert Roy Henry—The Classic “Academic Triple Threat”: Accomplished Researcher, Inspiring Teacher, and Compassionate Clinician (2020)

Robert (Bob) Roy Henry was born 12 March 1950 in Winnipeg, Manitoba, Canada, to Ken and Paula (nee Baldwin) Henry. His father was a train engineer and his mother a homemaker from Kent, England. Bob was raised in Transcon, a small town outside the city where most people joined the railway to make a living, and that is what his future looked like also. Bob and his wife, Denine McBeth, first met as teenagers. She was 16 and a cheerleader from a rival high school; he was 17 and owned a motorcycle.



Robert R. Henry, MD



The year following high school graduation he was able to find work at Manitoba Steel as a laborer. It was this experience that convinced him to pursue his education at the University of Winnipeg. Bob had a natural thirst for knowledge and thrived in the academic environment. During the course of his studies, he was in line for an academic excellence award (Canada’s recognition of students with outstanding achievements). However, Bob knew it would require another year at the University of Winnipeg and his interests had changed. He decided against pursuing the academic distinction and instead applied to and was accepted at the University of Manitoba in the field of medicine in 1971, graduating in 1975.

In 1973 he and Denine were married, and 2 years later their first son, Ryan, was born. During that time he was the president of the interns and residents’ association of Manitoba. After he graduated, he thought seriously of pursuing a specialty in cardiology at the University of Manitoba Health Science Centre. Unfortunately, on 11 September 1976, Bob, Denine, and Ryan were involved in a serious car accident that left …
Cemented and ingrowth fixation of the Miller-Galante prosthesis. Clinical and roentgenographic comparison after three- to six-year follow-up studies. (1990)

One hundred thirty-nine cemented and 132 cementless Miller-Galante total knee prostheses were followed between three and six years (average, 43-44 months). The fixation technique was based on patient age, bone quality, and ability to delay full-weight bearing. Clinical follow-up studies were possible on 116 cemented knees. Fifteen knees were lost because of death before the three-year follow-up study, and eight knees required component removal. One hundred twenty-three cementless knees were available for clinical follow-up studies; there were three deaths, and six failures required component removal. No cemented failure was due to fixation, and three cementless failures were due to lack of tibial ingrowth in two and pain of undetermined etiology in one. Preoperative knee scores were slightly significant with cemented knees averaging 48 points and cementless knees averaging 52 points. A similar significant difference was maintained at the final follow-up study. No significant differences were noted for pain, limp, or support scores. Average range of motion was similar in the two groups. Radiolucent lines about the femoral component were rare. Cementless tibial radiolucencies were partial in up to 20% of examined zones, and complete tibial tray radiolucency was seen in only three patients. No correlation between radiolucency and knee scores was seen.

DNA Migration and Separation on Surfaces with a Microscale Dielectrophoretic Trap Array (2007)

We studied the surface migration of DNA chains driven by a dc electric field across localized dielectrophoretic traps. By adjusting the length scale of the trap array, separation of a selected band of DNA was accomplished with a scaling exponent between mobility and number of base pairs similar to that obtained in capillary electrophoresis. We then provided a model, which predicts the trapping and extension of DNA chains at a dielectrophoretic trap responsible for the surface mobility and separation.
Functional Supramolecular Polymers (2012)

Supramolecular polymers can be random and entangled coils with the mechanical properties of plastics and elastomers, but with great capacity for processability, recycling, and self-healing due to their reversible monomer-to-polymer transitions. At the other extreme, supramolecular polymers can be formed by self-assembly among designed subunits to yield shape-persistent and highly ordered filaments. The use of strong and directional interactions among molecular subunits can achieve not only rich dynamic behavior but also high degrees of internal order that are not known in ordinary polymers. They can resemble, for example, the ordered and dynamic one-dimensional supramolecular assemblies of the cell cytoskeleton and possess useful biological and electronic functions.

Jitter Mitigation in High-Frequency Bandpass-Sampling OFDM Radios (2009)

This paper presents a new way to address and mitigate sampling jitter in high-frequency bandpass-sampling OFDM radio receivers. Baseband model for mapping the sampling jitter to certain type of phase noise is first presented, and stemming from this model, state-of-the-art phase noise mitigation techniques are then proposed to remove the jitter- induced signal distortion. Performances of the proposed jitter mitigation techniques are analyzed with extensive computer simulations in high-speed bandpass sampling multicarrier system context. In the link performance simulations, both additive white Gaussian noise (AWGN) and extended ITU-R vehicular A multipath (eVehA) radio channel types are used, combined with realistic sampling clock and jitter modelling.

Nonuniversal critical behavior in disordered pseudospin-1 systems (2019)

It is well known that for ordinary one-dimensional (1D) disordered systems, the Anderson localization length $\ensuremath{\xi}$ diverges as ${\ensuremath{\lambda}}^{m}$ in the long-wavelength limit ($\ensuremath{\lambda}\ensuremath{\rightarrow}\ensuremath{\infty}$) with a universal exponent $m=2$, independent of the type of disorder. Here, we show rigorously that pseudospin-1 systems exhibit nonuniversal critical behavior when they are subjected to 1D random potentials. In such systems, we find that $\ensuremath{\xi}\ensuremath{\propto}{\ensuremath{\lambda}}^{m}$ with $m$ depending on the type of disorder. For binary disorder, $m=6$ and the fast divergence is due to a super-Klein-tunneling effect. When we add additional potential fluctuations to the binary disorder, the critical exponent $m$ crosses over from 6 to 4 as the wavelength increases. Moreover, for disordered superlattices, in which the random potential layers are separated by layers of background medium, the exponent $m$ is further reduced to 2 due to the multiple reflections inside the background layer. To obtain the above results, we developed an analytic method based on a stack recursion equation. Our analytical results are in excellent agreement with the numerical results obtained by the transfer-matrix method. For pseudospin-1/2 systems, we find both numerically and analytically that $\ensuremath{\xi}\ensuremath{\propto}{\ensuremath{\lambda}}^{2}$ for all types of disorder, same as ordinary 1D disordered systems. Our analytical method provides a convenient way to obtain easily the critical exponent $m$ for general 1D Anderson localization problems.
Rotation Stability of the Cachet Angle-Supported Phakic Intraocular Lens (2013)

The study findings suggest that AcrySof Cachet angle-supported PIOLs offer moderate 1-year rotational stability. Because this type of IOL also corrects myopia effectively, it appears to be a good treatment option for myopic eyes. However, the rotation that occurs makes it unsuitable for cylinder corrections.

Insights into the Parting Limit for De-Alloying from Reconsideration of Atomistic Considerations (2007)

The parting limit for de-alloying of a homogeneous binary alloy is shown to be plausibly related to a kind of high- density percolation threshold. Kinetic Monte Carlo simulations are used to establish the relevant thresholds with and without surface diffusion.
Extensive longitudinal immune profiling reveals sustained innate immune activaton in COVID-19 patients with unfavorable outcome (2020)

COVID-19 differs substantially between individuals, ranging from mild to severe or even fatal. Heterogeneity in the immune response against SARS-COV-2 likely contributes to this. Therefore, we explored the temporal dynamics of key cellular and soluble mediators of innate and adaptive immune activation in relation to COVID-19 severity and progression. Forty-four patients with a PCR-proven diagnosis of COVID-19 were included. Extensive cellular (leukocytes and T-lymphocyte subsets) and serological immune profiling (cytokines, soluble cell surface molecules, and SARS-CoV-2 antibodies) was performed at hospital admission and every 3-4 days during hospitalization. Measurements and disease outcome were compared between patients with an unfavorable (IC admission and/or death) and favorable (all others) outcome. Patients with an unfavorable outcome had higher leukocyte numbers at baseline, mostly due to increased neutrophils, whereas lymphocyte and monocyte numbers were reduced. CRP, IL-6, CCL2, CXCL10, and GM-CSF levels were higher at baseline in the unfavorable group, whereas IL-7 levels were lower. SARS-CoV-2 antibodies were more frequently absent in the unfavorable group. Longitudinal analysis revealed delayed kinetics of activated CD4 and CD8 T-lymphocyte subsets in the unfavorable group. Furthermore, whereas CRP, IL-6, CXCL10, and GM-CSF declined in the favorable group, these cytokines declined with delayed kinetics, remained increased, or even increased further in the unfavorable group. Our data indicate a state of increased innate immune activation in COVID19-patients with an unfavorable outcome at hospital admission, which remained over time, as compared with patients with a favorable outcome.
Distributed Sequential Detection for Gaussian Shift-in-Mean Hypothesis\n Testing (2014)

This paper studies the problem of sequential Gaussian shift-in-mean\nhypothesis testing in a distributed multi-agent network. A sequential\nprobability ratio test (SPRT) type algorithm in a distributed framework of the\n\\emph{consensus}+\\emph{innovations} form is proposed, in which the agents\nupdate their decision statistics by simultaneously processing latest\nobservations (innovations) sensed sequentially over time and information\nobtained from neighboring agents (consensus). For each pre-specified set of\ntype I and type II error probabilities, local decision parameters are derived\nwhich ensure that the algorithm achieves the desired error performance and\nterminates in finite time almost surely (a.s.) at each network agent. Large\ndeviation exponents for the tail probabilities of the agent stopping time\ndistributions are obtained and it is shown that asymptotically (in the number\nof agents or in the high signal-to-noise-ratio regime) these exponents\nassociated with the distributed algorithm approach that of the optimal\ncentralized detector. The expected stopping time for the proposed algorithm at\neach network agent is evaluated and is benchmarked with respect to the optimal\ncentralized algorithm. The efficiency of the proposed algorithm in the sense of\nthe expected stopping times is characterized in terms of network connectivity.\nFinally, simulation studies are presented which illustrate and verify the\nanalytical findings.\n

The Challenge of Predicting the Shear Strength of Very Thick Slabs (2015)

Different building codes, such as the American Association of State Highway and Transportation Officials Load and Resistance Factor Design (AASHTO LRFD) and American Concrete Institute 318, provide different estimates for shear strength. This makes it difficult to evaluate the shear capacity of large structures. In this article, engineers predicted the load magnitude that would cause failure in shear spans. It was found that traditional shear design methods can overestimate the strength of very thick slabs without shear reinforcement. It is therefore recommended that a least the minimum shear reinforcement is used in very thick slabs.

Uncertainty guided semi-supervised segmentation of retinal layers in OCT\n images (2021)

Deep convolutional neural networks have shown outstanding performance in\nmedical image segmentation tasks. The usual problem when training supervised\ndeep learning methods is the lack of labeled data which is time-consuming and\ncostly to obtain. In this paper, we propose a novel uncertainty-guided\nsemi-supervised learning based on a student-teacher approach for training the\nsegmentation network using limited labeled samples and a large number of\nunlabeled images. First, a teacher segmentation model is trained from the\nlabeled samples using Bayesian deep learning. The trained model is used to\ngenerate soft segmentation labels and uncertainty maps for the unlabeled set.\nThe student model is then updated using the softly segmented samples and the\ncorresponding pixel-wise confidence of the segmentation quality estimated from\nthe uncertainty of the teacher model using a newly designed loss function.\nExperimental results on a retinal layer segmentation task show that the\nproposed method improves the segmentation performance in comparison to the\nfully supervised approach and is on par with the expert annotator. The proposed\nsemi-supervised segmentation framework is a key contribution and applicable for\nbiomedical image segmentation across various imaging modalities where access to\nannotated medical images is challenging\n
Asymmetric synthesis of 2,3-methanoleucine stereoisomers from common intermediates (2000)

2,3-Methanoamino acids are useful probes for studying the bioactive conformation of peptides and for investigating the effect of local conformational constraints on the activity of peptidomimetics. We synthesized all four stereoisomers of Cbz-protected 2,3-methanoleucine for incorporation into peptidomimetic inhibitors of calpain. While the synthesis of 2,3-methanoamino acids has been previously reported, our procedure offers a versatile route in which the pair of diastereomers of each geometric isomer was synthesized from a common intermediate.

Tachykinin Receptor Assays (1998)

Abstract The tachykinins are a family of peptides (including Substance P, neurokinin A and neurokinin B) that mediate a wide variety of biological activities, and smooth muscle contraction following stimulation of the tachykinin receptors has been well characterized, making isolated smooth muscle is a preferred tissue in which to study tachykinin receptors and their ligands. Three receptor subtypes have been isolated and cloned, and the protocols in this unit provide precise instruction on ligand‐binding assays using isolated tissues bearing the various subtypes (NK1, NK2 or NK3). A plethora of representative data illustrate expected results, so the investigator can compare and validate data obtained from test compounds.
