On the design of wearable and epidermal antennas for emerging medical applications (2017)

Recent years have witnessed rapid growth in medical applications based on wearable devices and sensors, which is attributed mainly due to the progress in wireless technologies and antennas. As the mobility and compactness of medical devices are becoming more demanding, wearable wireless sensors and antennas become an important candidate with their compact size, light weight, and ease of integration into clothes for Body Area Networks (BANs). This paper presents a state-of-the-art survey of the recent advances in wearable and epidermal antennas for medical applications, with emphasis on how flexible and light materials and textiles have a major effect on their design. While miniaturization and protecting the body against electromagnetic waves is of utter importance, the use of Electromagnetic Band Gap (EBG) structures is also emphasised. Some of the design challenges of wearable and epidermal antennas are highlighted as well.
Tri-Map Self-Validation Based on Least Gibbs Energy for Foreground Segmentation (2014)

The Bayesian framework forms a solid foundation for image segmentation. With this as a basis, an image is modeled as a Markov random field (MRF) with observations incorporated with a given tri-map. Although MRF-based methods have proved successful in interactive or supervised foreground segmentation, high-quality segmentation can be obtained only when the tri-map is sufficiently discriminative. We argue that the least Gibbs energy can be formulated as a goal function of a tri-map and can be a powerful means of validating the separability of predefined feature distributions. Further, we propose a split-and-validate strategy for decomposing the complex problem into a series of tractable subproblems, and suboptimal tri-map optimization is gradually achieved by making decisions between cluster-level operations. The splitting is determined by a novel combination of Bregman hierarchical clustering and an information theoretic method for realizing non-parametric clustering. We have evaluated our method against the Oxford Flower 17 and Caltech-UCSD Bird 200 benchmarks and show the superiority of tri-map self-validation in unsupervised foreground segmentation tasks.
Application of Composite Materials in High Pressure Technology (2014)

In recent years, the application of composite materials for high pressure technology has been on the rise. The use of composites allows reducing the weight, improving shape optimization, promoting ease of handling, and also increasing the vessel’s mechanical, impact, and corrosion behavior. This paper provides an overview of the research work conducted in recent years on application of composite materials in design and development of pressure vessels. The research work on composite materials, especially on structural health monitoring and self-healing would contribute to a continued growth of the applications of composite pressure vessels.

Non-Orthogonal Multiple Access for mmWave Drone Networks with Limited\n Feedback (2018)

Unmanned aerial vehicle (UAV) base stations (BSs) can be a promising solution\nto provide connectivity and quality of service (QoS) guarantees during\ntemporary events and after disasters. In this paper, we consider a scenario\nwhere UAV-BSs are serving large number of mobile users in a hot spot area\n(e.g., in a stadium). We introduce non-orthogonal multiple access (NOMA)\ntransmission at UAV-BSs to serve more users simultaneously considering user\ndistances as the available feedback for user ordering during NOMA formulation.\nWith millimeter-wave (mmWave) transmission and multi-antenna techniques, we\nassume UAV-BS generates directional beams and multiple users are served\nsimultaneously within the same beam. However, due to the limitations of\nphysical vertical beamwidth of the UAV-BS beam, it may not be possible to cover\nthe entire user region at UAV altitudes of practical relevance. During such\nsituations, a beam scanning approach is proposed to maximize the achievable sum\nrates. We develop a comprehensive framework over which outage probabilities and\nrespective sum rates are derived rigorously and we investigate the optimal\noperational altitude of UAV-BS to maximize the sum rates using our analytical\nframework. Our analysis shows that NOMA with distance feedback can provide\nbetter outage sum rates compared to orthogonal multiple access.\n

Are there socio-economic inequalities in utilization of predictive biomarker tests and biological and precision therapies for cancer? A systematic review and meta-analysis (2020)

These novel results indicate that there are socio-economic inequalities in predictive biomarker tests and biological and precision therapy utilization. This requires further investigation to prevent differences in outcomes due to inequalities in treatment with biological and precision therapies.
A Conserved Aromatic Lock for the Tryptophan Rotameric Switch in TM-VI of Seven-transmembrane Receptors (2009)

The conserved tryptophan in position 13 of TM-VI (Trp-VI:13 or Trp-6.48) of the CWXP motif located at the bottom of the main ligand-binding pocket in TM-VI is believed to function as a rotameric microswitch in the activation process of seven-transmembrane (7TM) receptors. Molecular dynamics simulations in rhodopsin demonstrated that rotation around the chi1 torsion angle of Trp-VI:13 brings its side chain close to the equally highly conserved Phe-V:13 (Phe-5.47) in TM-V. In the ghrelin receptor, engineering of high affinity metal-ion sites between these positions confirmed their close spatial proximity. Mutational analysis was performed in the ghrelin receptor with multiple substitutions and with Ala substitutions in GPR119, GPR39, and the beta(2)-adrenergic receptor as well as the NK1 receptor. In all of these cases, it was found that mutation of the Trp-VI:13 rotameric switch itself eliminated the constitutive signaling and strongly impaired agonist-induced signaling without affecting agonist affinity and potency. Ala substitution of Phe-V:13, the presumed interaction partner for Trp-VI:13, also in all cases impaired both the constitutive and the agonist-induced receptor signaling, but not to the same degree as observed in the constructs where Trp-VI:13 itself was mutated, but again without affecting agonist potency. In a proposed active receptor conformation generated by molecular simulations, where the extracellular segment of TM-VI is tilted inwards in the main ligand-binding pocket, Trp-VI:13 could rotate into a position where it obtained an ideal aromatic-aromatic interaction with Phe-V:13. It is concluded that Phe-V:13 can serve as an aromatic lock for the proposed active conformation of the Trp-VI:13 rotameric switch, being involved in the global movement of TM-V and TM-VI in 7TM receptor activation.

Translational value of mechanical and vasomotor properties of mouse isolated mesenteric resistance‐sized arteries (2015)

Mice are increasingly used in vascular research for studying perturbations and responses to vasoactive agents in small artery preparations. Historically, small artery function has preferably been studied in rat isolated mesenteric resistance-sized arteries (MRA) using the wire myograph technique. Although different mouse arteries have been studied using the wire myograph no establishment of optimal settings has yet been performed. Therefore, the purposes of this study were firstly to establish the optimal settings for wire myograph studies of mouse MRA and compare them to those of rat MRA. Second, by surveying the literature, we aimed to evaluate the overall translatability of observed pharmacological vasomotor responses of mouse MRA to those obtained in rat MRA as well as corresponding and different arteries in terms of vessel size and species origin. Our results showed that the optimal conditions for maximal active force development in mouse MRA were not significantly different to those determined in rat MRA. Furthermore, we found that the observed concentration-dependent vasomotor responses of mouse MRA to noradrenaline, phenylephrine, angiotensin II, sarafotoxin 6c, 5-hydroxytryptamine, carbachol, sodium nitroprusside, and retigabine were generally similar to those described in rat MRA as well as arteries of different sizes and species origin. In summary, the results of this study provide a framework for evidence-based optimization of the isometric wire myograph setup to mouse MRA. Additionally, in terms of translational value, our study suggests that mouse MRA can be applied as a useful model for studying vascular reactivity.

Ameliorative effect of chlorpromazine hydrochloride on visceral hypersensitivity in rats: possible involvement of 5‐HT2A receptor (2017)

Background and Purpose Visceral hypersensitivity is responsible for pathogenesis of irritable bowel syndrome (IBS). Therefore, its prevention can help avoid abdominal pain and discomfort in IBS. To find candidate drugs for visceral hypersensitivity, we screened existing medicines for their ability to prevent visceral sensitivity induced by colorectal distension (CRD) in rats and identified chlorpromazine, a typical antipsychotic drug, as a candidate compound. In this study, we investigated the effect of chlorpromazine on visceral hypersensitivity. Experimental Approach Visceral sensitivity (visceromotor response) was monitored by measuring the electrical activity of the abdominal external oblique muscle contraction in response to CRD using a barostat apparatus. Visceral hypersensitivity was induced by a colonic instillation of sodium butyrate or acetic acid in neonates. Key Results Oral administration of chlorpromazine suppressed butyrate‐induced visceral hypersensitivity to CRD. Interestingly, atypical antipsychotic drugs, quetiapine and risperidone, ameliorated butyrate‐induced visceral hypersensitivity, whereas the typical antipsychotic drugs, haloperidol and sulpiride, did not. Pharmacological analysis using specific inhibitors showed that a selective 5‐HT 2A receptor antagonist, ketanserin, suppressed butyrate‐induced visceral hypersensitivity, whereas a selective dopamine D 2 receptor antagonist, L‐741626, did not. Furthermore, the 5‐HT 2A receptor agonist AL‐34662 stimulated visceral sensitivity to CRD in healthy control rats but not in butyrate‐treated rats. These findings suggest that increased 5‐HT levels in the colon contribute to the induction of visceral hypersensitivity. Conclusions and Implications Our results indicate that chlorpromazine ameliorates visceral hypersensitivity and that the 5‐HT 2A receptor is a potential therapeutic target for treating abdominal pain and discomfort in IBS.
Nano Carbon Doped Polyacrylamide Gel Electrolytes for High Performance Supercapacitors (2021)

Novel polyacrylamide gel electrolytes (PGEs) doped with nano carbons with enhanced electrochemical, thermal, and mechanical properties are presented. Carboxylated carbon nanotubes (fCNTs), graphene oxide sheets (GO), and the hybrid of fCNT/GO were embedded in the PGEs to serve as supercapacitor (SC) electrolytes. Thermal stability of the unmodified PGE increased with the addition of the nano carbons which led to lower capacitance degradation and longer cycling life of the SCs. The fCNT/GO-PGE showed the best thermal stability, which was 50% higher than original PGE. Viscoelastic properties of PGEs were also improved with the incorporation of GO and fCNT/GO. Oxygen-containing functional groups in GO and fCNT/GO hydrogen bonded with the polymer chains and improved the elasticity of PGEs. The fCNT-PGE demonstrated a slightly lower viscous strain uninform distribution of CNTs in the polymer matrix and the defects formed within. Furthermore, ion diffusion between GO layers was enhanced in fCNT/GO-PGE because fCNT decreased the aggregation of GO sheets and improved the ion channels, increasing the gel ionic conductivity from 41 to 132 mS cm<sup>-1</sup>. Finally, MnO<sub>2</sub>-based supercapacitors using PGE, fCNT-PGE, GO-PGE, and fCNT/GO-PGE electrolytes were fabricated with the electrode-specific capacitance measured to be 39.5, 65.5, 77.6, and 83.3 F·g<sup>-1</sup>, respectively. This research demonstrates the effectiveness of nano carbons as dopants in polymer gel electrolytes for property enhancements.

Injectable Biodegradable Multimodal Mammography Marker (2019)

Introducing temporary markers for imaging studies is an idea, which in the proper clinical settings can be advantageous for patient compliance and in selected cases where a permanent marker is nondesirable. Hence, we developed injectable marker formulation using a biodegradable "pasty polymer" of poly(ricinoleic acid-<i>co</i>-sebacic acid) (PSA:RA) containing iodixanol and iron oxide as contrast agents that can serve as a visual marker for the region suspected to have tumor growth. The goal of this work is to noninvasively evaluate the visibility, shape, and degradation of the injectable PSA:RA formulation using magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound (US). Prescreening of the marker formulation was performed under MRI and CT scanning using agar gel phantom models with poly(l-lactide-<i>co</i>-ε-caprolactone) (PCL:LA) solid inserts (clips) that contained varying combinations of the contrast agents. The contrast agent combination with the PCL:LA clip that had the best visibility in both MRI and CT was selected and additionally tested as in PSA:RA formulation. Further, we evaluated the PSA:RA marker placement in bovine liver and poultry muscles. The PSA:RA formulation is predictable with good MRI, CT, and US visibility and shows no <i>in vivo</i> systemic toxicity symptoms when implanted subcutaneously in mice. Further, the advantage of PSA:RA formulation is its undefined shape and ease of injecting through a small gauge needle, making it possible to reach into the regions of the body.

Using artificial intelligence for CyanoHAB niche modeling: discovery and visualization of Microcystis–environmental associations within western Lake Erie (2014)

Cyanobacterial harmful algal blooms (CyanoHABs), mainly composed of the genus Microcystis, occur frequently throughout the Laurentian Great Lakes. We used artificial neural networks (ANNs) involving 31 hydrological and meteorological predictors to model total phytoplankton (as chlorophyll a) and Microcystis biomass from 2009 to 2011 in western Lake Erie. Continuous ANNs provided modeled-measured correspondences (and modeling efficiencies) ranging from 0.87 to 0.97 (0.75 to 0.94) and 0.71 to 0.90 (0.45 to 0.88) for training–cross-validation and test data subsets of chlorophyll a concentrations and Microcystis biovolumes, respectively. Classification ANNs correctly assigned up to 94% of instances for Microcystis presence–absence. The influences of select predictors on phytoplankton and CyanoHAB niches were visualized using biplots and three-dimensional response surfaces. These then were used to generate mathematical expressions for the relationships between modeled CyanoHAB outcomes and the direct and interactive influences of environmental factors. Based on identified conditions (∼40 to 50 μg total phosphorus (TP)·L −1 , 22 to 26 °C, and prolonged wind speeds less than ∼19 km·h −1 ) underlying the likelihood of occurrence and accumulation of phytoplankton and Microcystis, a “target” concentration of 30 μg TP·L −1 appears appropriate for alleviating blooms. ANNs generated robust ecological niche models for Microcystis, providing a predictive framework for quantitative visualization of nonlinear CyanoHAB–environmental interactions.
Disruptive mutations in TANC2 define a neurodevelopmental syndrome associated with psychiatric disorders (2019)

Postsynaptic density (PSD) proteins have been implicated in the pathophysiology of neurodevelopmental and psychiatric disorders. Here, we present detailed clinical and genetic data for 20 patients with likely gene-disrupting mutations in TANC2-whose protein product interacts with multiple PSD proteins. Pediatric patients with disruptive mutations present with autism, intellectual disability, and delayed language and motor development. In addition to a variable degree of epilepsy and facial dysmorphism, we observe a pattern of more complex psychiatric dysfunction or behavioral problems in adult probands or carrier parents. Although this observation requires replication to establish statistical significance, it also suggests that mutations in this gene are associated with a variety of neuropsychiatric disorders consistent with its postsynaptic function. We find that TANC2 is expressed broadly in the human developing brain, especially in excitatory neurons and glial cells, but shows a more restricted pattern in Drosophila glial cells where its disruption affects behavioral outcomes.
Polycrystalline anatase titanium dioxide microring resonators with negative thermo-optic coefficient (2015)

We fabricate polycrystalline anatase TiO2 microring resonators with loaded quality factors as high as 25,000 and average losses of 0.58&#x2009;&#x2009;dB/mm in the telecommunications band. Additionally, we measure a negative thermo-optic coefficient dn/dT of &#x2212;4.9&#xB1;0.5&#xD7;10&#x2212;5&#x2009;&#x2009;K&#x2212;1. The presented fabrication uses CMOS-compatible lithographic techniques that take advantage of substrate-independent, non-epitaxial growth. These properties make polycrystalline anatase a promising candidate for the implementation of athermal, vertically integrated, CMOS-compatible nanophotonic devices for nonlinear applications.
The design, fabrication and evaluation of a MEMS PZT cantilever with an integrated Si proof mass for vibration energy harvesting (2008)

A microelectromechanical system (MEMS) piezoelectric energy harvesting device, a unimorph PZT cantilever with an integrated Si proof mass, was designed for low vibration frequency and high vibration amplitude environment. Pt/PZT/Pt/Ti/SiO2 multilayered films were deposited on a Si substrate and then the cantilever was patterned and released by inductively coupled plasma reactive ion etching. The fabricated device, with a beam dimension of about 4.800 mm × 0.400 mm × 0.036 mm and an integrated Si mass dimension of about 1.360 mm × 0.940 mm × 0.456 mm produced 160 mVpk, 2.15 μW or 3272 μW cm−3 with an optimal resistive load of 6 kΩ from 2g (g = 9.81 m s−2) acceleration at its resonant frequency of 461.15 Hz. This device was compared with other demonstrated MEMS power generators.
