Dn10, a New Gene Conferring Resistance to Russian Wheat Aphid Biotype 2 in Iranian Wheat Landrace PI 682675 (2018)

Russian wheat aphid [RWA, Diuraphis noxia (Mordvilko)] is a serious pest of wheat ( Triticum aestivum L.) and barley ( Hordeum vulgare L.) that causes heavy yield losses in many countries, and RWA biotype 2 (RWA2) is virulent to most RWA resistance genes. The objective of this study was to characterize a gene for resistance to RWA2 in Iranian landrace PI 682675, a single‐plant selection from PI 624151. F 2:3 and F 3:4 families derived from cross PI 682675 × Zhengyou 6 were used to map the resistance gene. PI 682675 carries a dominant resistance gene, Dn10 , flanked by simple sequence repeat markers Xgwm437 and Xwmc488 on chromosome 7DL. Physical mapping indicated that Dn10 resides in bin 7DL 0.1 to 0.77, whereas Dn2401 and Dn626580 that also confer resistance to RWA2 were physically mapped to 7DS. Allelism tests showed that Dn10 was located ∼17.4 cM from Dn2401 and 22.2 cM from Dn626580 . Dn10 is a new resistance gene that should be used widely in wheat breeding.

Motor impairment in Wilson's disease, II: slowness of speech (2009)

The maximal syllable production rate (MSPR) and the ability to reproduce a given target frequency in the 1 to 8 Hz range by repeating the short syllable "ta" was tested in 20 patients with Wilson's disease (WD) and 20 normal subjects. MSPR was significantly reduced in the WD-patients. In the 1 to 5 Hz range normal subjects as well as WD-patients tended to produce slightly higher frequencies than the target frequencies. This hastening was maximal in normals between 4 to 5 Hz whereas in the WD-patients hastening mainly occurred between 3 to 4 Hz. The test results showed a considerable variation across the patients. This variation can be interpreted on the basis of the theory of coupled oscillators. Comparison of speech and finger movements revealed a highly significant correlation between MSPR and the highest possible frequency of voluntary alternating index finger movements. As an application of the presented test treatment effects on speech movements were demonstrated.

Continuous-Wave Operation of Pure Blue AlGaN-Cladding-Free Nonpolar InGaN/GaN Laser Diodes (2010)

We present the first reported continuous-wave (CW) operation of pure blue AlGaN-cladding-free (ACF) nonpolar m-plane InGaN/GaN laser diodes (LDs). CW lasing was achieved at a wavelength of 461 nm and a threshold current density of 4.1 kA/cm2 for LDs with an InGaN-based separate confinement heterostructure (SCH) waveguide design. The devices showed a 9 nm/decade blue-shift of spontaneous emission wavelength with increasing current density, a characteristic temperature of 156 K, a red-shift with increasing stage temperature of 0.05 nm/K, and an estimated thermal impedance of 60 K/W.
Microminiature Monitor for Vital Electrolyte and Metabolite Levels of Astronauts (2004)

Ions, such as proton (pH) and potassium, play a crucial role in body fluids to maintain proper basic functioning of cells and tissues. Metabolites, such as glucose, control the energy available to the entire human body in normal as well as stress situations, and before, during, and after meals. These molecules diffuse easily between blood in the capillaries and the interstitial fluid residing between cells and tissues. We have developed and approach to monitoring of critical ions (called electrolytes) and glucose in the interstitial fluid under the human skin. Proton and potassium levels sensed using optode technology that translates the respective ionic concentrations into variable colors of corresponding ionophore/dye/polymeric liquid membranes. Glucose is monitored indirectly, by coupling through immobilized glucose oxidase with local pH that is then detected using a similar color scheme. The monitor consists of a tiny plastic bar, 100-200 microns wide and 1-2 mm long, placed just under the skin, with color changing spots for each analyte as well as blanks. The colors are read and translated into concentration values by a CCD camera. Direct optical coupling between the in vivo sensing bar and the ex vivo detector device requires no power, and thus eliminates the need for wires or optical fibers crossing the skin. The microminiature bar penetrates the skin easily and painlessly, so that astronauts could insert it themselves. The approach is fully compatible with telemetry in space, and thus, in vivo clinical data will be available real time in the Earth based command center once the device is fully developed. The information provided can be used for collecting hitherto unavailable vital data on clinical effects of space travel. Managing clinical emergencies in space with the sensor already in place should also become much more efficient than without a continuous monitor, as is currently the case. Civilian applications may include better glucose control of patients with moderate to severe diabetes: a growing health problem in the US and World-wide.
Protocols and stability analysis for energy harvesting TDMA systems with/without relaying (2013)

This paper deals with time-division multiple access (TDMA) in wireless networks with bursty data traffic and energy harvesting capabilities at the source nodes. Several TDMA-based transmission strategies that incorporate different levels of “as-sistance” for the energy-constrained sources are investigated and analyzed in terms of stable throughput. Specifically, we study the stability region for a TDMA policy with assistance of a) channel state information (CSI) at the sources, b) orthogonal relaying cooperation, c) cognitive radio relaying cooperation and d) full-duplex (FD) relaying cooperation. The transmission parameters associated with the proposed strategies are also optimized. We observe that CSI results in significant energy savings and enlarge the stability region of the network while FD cooperation, which exploits the multipacket reception characteristics of the channel, provides the best performance.
Using web search engines to improve text recognition (2008)

In this paper we introduce a framework for automated text recognition from images. We first describe a simple but efficient text detection and recognition method based on analysis of maximally stable extremal regions (MSERs) and simple template matching which allows to provide initial character recognition results. The main emphasis of the paper is on introducing a novel method for exploiting contextual information to improve the obtained recognition results. We propose to analyze the results of Web search engine queries on two levels of detail, which both allow to significantly improve the overall text recognition performance. The experimental evaluations on reference data sets prove that even based on a low quality single character recognition method the proposed Web search engine extension enables reasonable text recognition results.
Design and test of a 3D printed acoustic fresnel lens (2018)

Focused ultrasound has a variety of applications. High-intensity ultrasound is becoming a common tool in medicine for non-invasive interventions such as tissue ablation of cancer tumors. Low intensity focused acoustic waves can also be employed for other applications such as tissue stimulation, particle tweezing or imaging. In this work a preliminary study on the focusing properties of 3D printed acoustic lenses based on Fresnel zone plate theory was done. A finite element model was used to validate the design. A design was fabricated by means of 3D printing. Two measurement setups are were used to characterize the acoustic properties of the lens. Good qualitative agreement is observed between simulation and measurement data.
The TSC-PFed Architecture for Privacy-Preserving FL (2021)

In this paper we will introduce our system for trust and security enhanced customizable private federated learning: TSC-PFed. We combine secure multiparty computation and differential privacy to allow participants to leverage known trust dynamics which allow for increased ML model accuracy while preserving privacy guarantees and introduce an update auditor to protect against malicious participants launching dangerous label flipping data poisoning. We additionally introduce customizable modules into the TSC-PFed ecosystem which (a) allow users to customize the type of privacy protection provided and (b) provide a tiered participant selection approach which considers variation in privacy budgets.
Study of Temperature and Time Dependent Performance Alteration of Silver Ion-exchanged Waveguides in Glass (2020)

Single-mode glass waveguides for a wavelength of 1310 nm were designed in two different glasses with single-mode optical fiber coupling loss of 0.3 dB per interface. The temperature dependent diffusivity of both glasses is studied to explore the thermal alteration of the refractive index profile which can lead to less mode confinement and an increase in optical fiber coupling loss over time. For the model, diffusivity data is collected at higher temperature and extrapolated down to operation temperature range with a peak temperature of 110 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">o</sup> C. The data is verified with experimental data from long term experiments. We study the refractive index change of both glasses and the impact on optical performance over time. One of the selected glasses has almost no alteration and is meeting the data center lifetime requirements of five years. Waveguides were fabricated in both glasses and the lowest propagation loss was measured to be 0.048 dB/cm at a wavelength of 1310 nm.
Overview of Positioning in 5G New Radio (2019)

Accurate and real time location knowledge is an important requirement for various new services like e.g. emergency services, vehicular related use cases and factories of the future. 3GPP Rel-16 will specify positioning support for 5G New Radio (NR). A study item was concluded in March 2019 to investigate positioning support for NR Rel-16 and a follow up work item is in progress to specify positioning support for Rel-16. Several positioning solutions will be supported in 5G NR. The operation in higher carrier frequencies and utilization of massive antenna arrays provides additional degrees of freedom to improve the positioning accuracy compared to LTE. Rel-16 positioning is targeting to <; 3 meters positioning accuracy for some use cases. Next 3GPP Releases are expected to further specify methods for sub-meter accuracy and low latency. In this work an overview of the positioning work within 3GPP is given, highlighting both architectural and physical layer aspects.
A Complexed Sol-Gel (CSG) Approach to High Surface Area (HSA) Durable Ultra Active Platinum-Ruthenium Electro-Catalysts for Direct Methanol Fuel Cells (2014)

Direct Methanol Fuel Cell (DMFC) is a promising power source for continuous generation of energy without evolution of any toxic by-products and greenhouse gases. Pt-Ru has been the accepted gold standard anode electro-catalyst for DMFC, but significant advances are required to enhance its performance and stability. A complexed sol-gel (CSG) approach has been used to develop nanostructured powder materials. Herein we report a novel CSG process to synthesize nanoparticulate high specific surface area (HSA), completely unsupported Pt(Ru) based electro-catalyst exhibiting three fold higher electrochemically active surface area (ECSA) and ultra high electrochemical performance compared to commercially available Johnson Matthey Pt-Ru black catalyst, the currently accepted gold standard. Furthermore, in identical single full cell DMFC configuration tests for methanol oxidation, current and power densities ∼40% higher than that displayed by Johnson Matthey catalyst is achieved.

Spatiotemporal mask affects detection and Vernier acuity (1990)

Vernier acuity for abutting stimuli is almost independent of exposure duration providing the target remains equally visible i.e. if the effect of time on detection is accounted for (Hadani et al., 1984; Waugh and Levi, ARVO 1990). Recently Watt 1 reported that for a variety of spatial discrimination tasks using line stimuli, thresholds continue to improve with time at least until 1000 msec. However, in Watt's experimental paradigm, a random noise mask immediately followed presentation of the discrimination target. We measured foveal line detection and abutting line vernier thresholds with and without a random noise mask immediately following the stimulus. Stimuli were presented on a uniform background of 132 cd/m 2 . A self-paced rating-scale method of constant stimuli with feedback was used. The mask produced a significant increase in vernier thresholds for durations less than about 200 msec. However, it also increased detection thresholds over this range of durations. For masked vernier stimuli equated for visibility, no systematic effect of time on vernier acuity was found. These results suggest that for equally visible stimuli, no additional time is required to scan through a range of spatial filters in order to obtain the finest vernier thresholds.
Structural basis of LAIR1 targeting by polymorphic Plasmodium RIFINs (2021)

RIFIN, a large family of Plasmodium variant surface antigens, plays a crucial role in malaria pathogenesis by mediating immune suppression through activation of inhibitory receptors such as LAIR1, and antibodies with LAIR1 inserts have been identified that bind infected erythrocytes through RIFIN. However, details of RIFIN-mediated LAIR1 recognition and receptor activation have been unclear. Here, we use negative-stain EM to define the architecture of LAIR1-inserted antibodies and determine crystal structures of RIFIN-variable 2 (V2) domain in complex with a LAIR1 domain. These structures reveal the LAIR1-binding region of RIFIN to be hydrophobic and membrane-distal, to exhibit extensive structural diversity, and to interact with RIFIN-V2 in a one-to-one fashion. Through structural and sequence analysis of various LAIR1 constructs, we identify essential elements of RIFIN-binding on LAIR1. Furthermore, a structure-derived LAIR1-binding sequence signature ascertained >20 LAIR1-binding RIFINs, including some from P. falciparum field strains and Plasmodium species infecting gorillas and chimpanzees.

HbA1c testing is being performed on a substantial proportion of nondiabetic patients. On average, patients with diabetes in Alberta receive 1.5 HbA1c tests per year. However, we observed regional differences in the frequency of testing and variation in compliance with clinical practice guidelines.
A 1-MHz Relaxation Oscillator Core Employing a Self-Compensating Chopped Comparator Pair (2019)

An improved relaxation oscillator core is designed and fabricated in 0.35-μm CMOS process, occupying the area of 0.032 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and consuming around 160 μW while running at 1 MHz. Employing a self-compensating chopped comparator structure, the designed oscillator exhibits a significant improvement in the frequency stability and control linearity, at the same time retaining a fast start-up and having a minimal overhead in the power consumption and area. Measured on 8 test chips, the frequency variation against temperature is ±0.26% in the temperature range from -40 to 125 °C, and the line sensitivity is ±0.08 %/V with the supply voltage changing from 3.0 to 4.5 V. The typical distortion parameters of the control characteristic are HD <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> = -61.7 dB and HD <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> = -93.2 dB at △f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">osc</sub> = 500 kHz.

Synthesis of Cs3MnBr5 Green Phosphors Using an Eco-Friendly Evaporative Crystallization Process (2022)

Green (G) and red (R) light-emitting materials, such as quantum dots, perovskite nanocrystals, and inorganic phosphor powders, owing to their excellent optical characteristics, have attracted researchers' attention as color-conversion materials for lighting and display applications. However, these materials contain environmentally harmful elements, such as Pb or Cd, and/or they are synthesized using environmentally harmful synthetic approaches and conditions, involving the use of organic solvents, high pressure, high temperature, harsh atmosphere, and long reaction time. In this study, as an eco-friendly synthetic approach to synthesize lead-free Cs<sub>3</sub>MnBr<sub>5</sub> G powder phosphor, we suggest an evaporative crystallization process of aqueous reactant solution. This synthetic process does not use toxic elements or solvents and the crystallization process utilizes only low reaction temperature and short reaction time under air atmosphere conditions. We successfully synthesized Cs<sub>3</sub>MnBr<sub>5</sub> green powder phosphor, with excellent optical properties, by evaporative heating of a 200 nm syringe-filtered solution at 150 °C for 2 h. The synthesized Cs<sub>3</sub>MnBr<sub>5</sub> phosphors have a photoluminescence quantum yield of 66.3%, a peak wavelength of 520 nm, a narrow bandwidth of 38 nm, and a photoluminescence decay time of 0.34 ms under blue excitation. This phosphor is expected to be a useful alternative G-emitting material that can compete with commercial green quantum dots, perovskite nanocrystals, or inorganic phosphors.
Transcriptional Changes in the Hookworm, Ancylostoma caninum, during the Transition from a Free-Living to a Parasitic Larva (2008)

The Role of Interleukin-4 and Interleukin-13 in the Non-Immunologic Aspects of Asthma Pathogenesis (2003)

Bronchial asthma is a complex disease characterized by airway inflammation involving a Th2-cytokine, interleukin (IL)-13. A substantial body of evidence has accumulated pointing to the pivotal role of IL-13 in the pathogenesis of bronchial asthma. The evidence is categorized as (i) analyses of mouse models, (ii) expression of these cytokines in the bronchial lesions, and (iii) genetic association of the signaling molecules of these cytokines. In addition, the molecular mechanism of the signal transduction of IL-13 has also been well characterized. We have applied microarray analyses to human bronchial epithelial cultures to search for genes regulated by IL-13 and have identified a subset of disease-relevant genes by comparison with cDNA libraries derived from normal and asthmatic bronchial biopsies. Expression of squamous cell carcinoma antigen-1 (SCCA1) and SCCA2, the cysteine and serine protease inhibitors, respectively, was the highest in the bronchial epithelial cells stimulated by IL-4 and IL-13 and was augmented in the asthmatic cDNA library. Furthermore, serum levels of SCCA were also elevated in asthmatic patients. Taken together, it was supposed that SCCA may play some role in the pathogenesis of bronchial asthma, and measuring its serum level may be relevant for diagnosing or monitoring the status of bronchial asthma.
Floc structure and the role of cations (2001)

Cations have been found to influence the settling and dewatering characteristics of biological sludges. This research was directed at investigating the role of iron in floc stability of sensitivity to shear and in the response to anaerobic and aerobic digestion. Our data shows that iron may contribute to floc strength and it appears that the deterioration in sludge dewatering during anaerobic digestion is associated with the reduction and solubilization of iron. Further, it is the presence of proteins in solution that contributes to poor dewatering and to the demand for conditioning chemicals. The addition of iron for improving dewatering shows that iron may selectively coagulate solution proteins.
