Phase Transition in Frequency Agile Radar Using Compressed Sensing (2020)

Frequency Agile Radar (FAR) has improved anti-jamming performance over traditional pulse-Doppler radars under complex electromagnetic circumstances. To reconstruct the range-Doppler information in FAR, many compressed sensing (CS) methods including standard and block sparse recovery have been applied. In this paper, we study phase transitions of range-Doppler recovery in FAR using CS. In particular, we derive the closed-form phase transition curves associated with block sparse recovery and complex Gaussian matrices, based on prior results of standard sparse recovery under real Gaussian matrices. Empirical simulations validate the obtained curves, which lead to tight bounds on the radar and target parameters that guarantee exact recovery of targets' range-Doppler information.
Photo-accelerated fast charging of lithium-ion batteries (2019)

Due to their exceptional high energy density, lithium-ion batteries are of central importance in many modern electrical devices. A serious limitation, however, is the slow charging rate used to obtain the full capacity. Thus far, there have been no ways to increase the charging rate without losses in energy density and electrochemical performance. Here we show that the charging rate of a cathode can be dramatically increased via interaction with white light. We find that a direct exposure of light to an operating LiMn<sub>2</sub>O<sub>4</sub> cathode during charging leads to a remarkable lowering of the battery charging time by a factor of two or more. This enhancement is enabled by the induction of a microsecond long-lived charge separated state, consisting of Mn<sup>4+</sup> (hole) plus electron. This results in more oxidized metal centers and ejected lithium ions are created under light and with voltage bias. We anticipate that this discovery could pave the way to the development of new fast recharging battery technologies.
Intersubband Polaritonics in Dielectric Metasurfaces (2020)

We experimentally demonstrate a metasurface that supports tailorable polaritons arising from strong coupling between Mie modes of dielectric nanoresonators and intersubband transitions of semiconductor quantum wells that are embedded inside the resonator.
High expression of the evolutionarily conserved α/β hydrolase domain containing 6 (ABHD6) in Ewing tumors (2009)

Despite improvements in the treatment of patients with Ewing family tumors (EFT), the prognosis for patients with advanced disease is still unsatisfactory. Recently, we identified lipase I as an EFT-associated gene that might be interesting for the development of new immunological or pharmacological treatment strategies. Lipase I is a member of the large protein superfamilies of alpha/beta hydrolases and serine hydrolases. In the present paper we describe high expression of another member of these superfamilies in EFT. By DNA microarray data base mining we found exceptional high expression of alpha/beta hydrolase domain containing 6 (ABHD6) in EFT but not in other sarcomas. Expression of ABHD6 in EFT correlated with expression of another EFT-associated gene, aristaless. Analysis of ABHD6-associated GGAA microsatellites revealed shorter microsatellites in EFT with lack of ABHD6 expression. ABHD6 homologues were found in varying chordata but not in other animal species. Based on homology modeling we predicted the 3D-structure of ABHD6, which shows high similarity with bacterial homoserine transacetylases. High expression of ABHD6 in EFT in comparison to normal tissues and other tumors suggests that ABHD6 might be an interesting new diagnostic or therapeutic target for EFT. However, knock down of ABHD6 in EFT cells did not inhibit tumor cell growth.
GETTING AT THE CRUX OF GLYCOLYTIC FLUX: DIRECT MEASUREMENT OF GLYCOLYSIS DURING AND AFTER EXERCISE (1999)

1156 During exercise, glycolysis occurs simultaneously with numerous other cellular processes and is thus difficult to quantify. During ischemic recovery from ischemic exercise, however, flux through the glycolytic pathway may be observed in isolation and measured directly. The purposes of this study were (1) to determine whether the initial post-exercise glycolytic flux is an accurate measure of the flux during exercise and (2) to characterize the time course of changes in flux at the start and end of exercise. Blood flow to subjects' dorsiflexor muscles was stopped via the inflation of a pneumatic cuff wrapped around the thigh. After intracellular oxygen stores were depleted, subjects performed rapid voluntary dorsiflexions while phosphorus-31 nuclear magnetic resonance spectra of the active muscle group were acquired. Glycolytic fluxes were computed from the observed changes in muscle pH and [phosphocreatine]. The flux was essentially unchanged from its basal level after 12 contractions but rose to 43% of its eventual steady-state rate by the 30th contraction. Conversely, post-exercise flux was initially equal to the flux calculated during exercise but declined to resting levels within 30 seconds of the end of exercise. We conclude that (1) initial post-exercise glycolytic flux is a direct, accurate measure of flux during voluntary exercise and that (2) there is a latency in the glycolytic response to changes in muscle activity.

III-V-on-Si/SiN lasers realized using micro-transfer-printing (2021)

Micro-transfer-printing (µTP) enables the intimate integration of diverse non-inherent functionalities on a target substrate and hence allows for the realization of complex photonic integrated circuits (PICs) with small footprint. By employing a polydimethylsiloxane (PDMS) elastomeric stamp with an array of posts, a large number of micro-components can be integrated on a target wafer in one transfer printing operation, which leads to substantial cost reduction of the resulting PICs. This paper discusses the use of µTP for the realization of III-V lasers on Si and SiN PICs and summarizes the recent progress that has been made in this field.
Finding Intermediary Topics Between People of Opposing Views: A Case Study (2015)

In micro-blogging platforms, people can connect with others and have conversations on a wide variety of topics. However, because of homophily and selective exposure, users tend to connect with like-minded people and only read agreeable information. Motivated by this scenario, in this paper we study the diversity of intermediary topics, which are latent topics estimated from user generated content. These topics can be used as features in recommender systems aimed at introducing people of diverse political viewpoints. We conducted a case study on Twitter, considering the debate about a sensitive issue in Chile, where we quantified homophilic behavior in terms of political discussion and then we evaluated the diversity of intermediary topics in terms of political stances of users.
Electrical properties and local structure ofn-type conducting amorphous indium sulphide (2004)

Abstract An n-type amorphous chalcogenide, In49S51, having a band gap of 1.9eV, has been found. The conductivity in as-prepared films was ∼10−4 S cm−1, which increased to 1 × 10−1 S cm−1 on post-annealing at 125°C in vacuum, accompanied by a reduction in the sulphur content of the films. TEM observations showed the amorphous nature of the films before and after annealing. Both Seebeck and Hall coefficients are negative, indicating that the major carriers are electrons. The Hall mobility can be as large as 26 cm2 V−1 s−1 at 300 K. No significant changes to the optical absorption were observed upon annealing. Analysis of the X-ray radial distribution function reveals that the sulphur atoms have four-fold coordination, making the structure more rigid than conventional amorphous chalcogenides in which the chalcogen is alloyed to elements of group IV or V of the periodic table. We tentatively associate the electron carrier generation with the formation of sulphur vacancies. Notes Email: satoru-narushima@agc.co.jp.

A Wireless EV Charging Topology With Integrated Energy Storage (2020)

This article presents a wireless power transfer topology based on inductive power transfer (IPT) with integrated supercapacitor (SC) energy storage. The proposed topology is suitable for dynamic charging of electric vehicles (EVs), where pulses of energy must be processed without placing excessive strain on the utility grid or the EV battery. This topology extends the functionality of a typical LCL-tuned bidirectional IPT system by adding the ability to store energy in an SC in a controlled manner. Operation of the system is described in terms of the switching patterns and control variables required to transfer energy between the input, output, and the SCs. A mathematical model that predicts the overall transfer of power between the input, output, and SCs is presented along with experimental results at a nominal power level of 3.8 kW to validate the model and the topology under a variety of typical operating conditions.

Insulin autoimmune syndrome (Hirata Disease) in European Caucasians taking α‐lipoic acid (2013)

This is the first report of LA-related IAS in Caucasians who possess the HLA-DRB1*04:03 allele, implicating this allele in the genetic susceptibility to IAS in Caucasians. The greater occurrence of the HLA-DRB1*04:03 allele in Caucasian and other populations, combined with the growing use of LA in developed countries, may be a future predictor of additional cases of IAS.
Ultrasound Sensor for Process and Fouling Monitoring in Emulsion Polymerization Processes (2022)

In order to produce emulsion polymerization in continuous systems, it is necessary to monitor the process very precisely. To do so as energy- and cost-efficiently as possible, monitoring of fouling is essential to perfectly adjust cleaning cycles. Therefore, an online measurement method is needed, which is not commercially available for these applications. In the present work a measuring system is developed, which can be integrated in continuous systems, and which can measure the fouling and evaluate it in real time. In addition, the reaction and substance properties in the process are to be monitored. The measurement system is realized with a single channel ultrasound echo measurement.
The Invention of WM382, a Highly Potent PMIX/X Dual Inhibitor toward the Treatment of Malaria (2022)

Drug resistance to first-line antimalarials-including artemisinin-is increasing, resulting in a critical need for the discovery of new agents with novel mechanisms of action. In collaboration with the Walter and Eliza Hall Institute and with funding from the Wellcome Trust, a phenotypic screen of Merck's aspartyl protease inhibitor library identified a series of plasmepsin X (PMX) hits that were more potent than chloroquine. Inspired by a PMX homology model, efforts to optimize the potency resulted in the discovery of leads that, in addition to potently inhibiting PMX, also inhibit another essential aspartic protease, plasmepsin IX (PMIX). Further potency and pharmacokinetic profile optimization efforts culminated in the discovery of <b>WM382</b>, a very potent dual PMIX/X inhibitor with robust <i>in vivo</i> efficacy at multiple stages of the malaria parasite life cycle and an excellent resistance profile.
Study of the Strong Coupling Constant UsingW+JetProcesses (1995)

The ratio of the number of $W+1$ jet to $W+0$ jet events is measured with the D0 detector using data from the 1992--93 Tevatron Collider run. For the $W\ensuremath{\rightarrow}e\ensuremath{\nu}$ channel with a minimum jet ${E}_{T}$ cutoff of 25 GeV, the experimental ratio is $0.065\ifmmode\pm\else\textpm\fi{}0.003\left(\mathrm{stat}\right)\ifmmode\pm\else\textpm\fi{}0.007\left(\mathrm{syst}\right)$. Next-to-leading order QCD predictions for various parton distributions agree well with each other and are all over 1 standard deviation below the measurement. Varying the strong coupling constant ${\ensuremath{\alpha}}_{s}$ in both the parton distributions and the partonic cross sections simultaneously does not remove this discrepancy.

This paper presents a compact 28 GHz vertically-polarized SIW-fed dipole for future 5G smartphones. The dipole is implemented using vias in standard PCB process to fit at the edge of the smartphone providing fan-beam in the elevation plane for wide coverage. Additional parasitic vias are employed in front of the dipole to serve as directors for enhanced gain achieving 7 dBi peak gain. Also a via fence is added surrounding the dipole to suppress back radiation. The fabricated prototype achieves 2.7 GHz matching bandwidth, 96% radiation efficiency, 16 dB front-to-back radiation ratio and 96° fan-beam coverage in the elevation plane.
Abstract 9: Temperature-responsive Cell Delivery Biopolymers for Cardiac Tissue Engineering (2015)

Background: Advances in cell therapy and material science have made tissue engineering a promising strategy for heart regeneration. We developed an injectable biomimetic reverse thermal gel (RTG) that is liquid at room temperature but gel-like at body temperature, with the ultimate goal of being able to serve as a vehicle for cell-based delivery (liquid) to targeted tissue areas (gel-phase at 37°C). In this study we tested the suitability of this biomimetic RTG on cell viability. Methods and results: We tested different biomimetic RTG systems with and without the chemical incorporation of lysine. In vitro 3D culture experiments were performed with neonatal rat ventricular myocytes (NRVM) by mixing 3x104 cells with 50 μl of polymeric solution and allowing gel formation at 37°C. The cultured cells were incubated for 21 days. For controls we used NRVMs plated on 2D traditional gelatin coated dishes. We found that the 3D polymeric matrix induces rapid coordinated contraction with improved functionality when compared with standard 2D-cultured NRVM. By immunostaining for the morphology of the sarcomere (alpha-actinin) and DAPI, we also observed that the 3D polymeric matrix stimulates cells to spread and form 3D syncytia. Conclusion: These proof-of-concept results demonstrate long-term cell viability in this unique biomimetic system and therefore provide feasibility of a polymeric cell delivery system that permits reversible liquid-to-gel transition at body temperature. These results offer potential for a tissue engineering approach to cardiac regeneration.
Numerical investigations on load transfer of mooring line considering chain–seabed dynamic interaction (2020)

Taut or semi-taut mooring lines are often used in deep-sea area to connect the floating structures to the anchors in the seabed. In previous studies, the quasi-static analysis method was adopted to assess the load transfer of the mooring line. However, the inertia effect of mooring line and chain–seabed dynamic interaction cannot be neglected in practice. In this paper, the soil strain rate effect was incorporated in the chain–seabed dynamic analyses, and the load transfer mechanism of mooring line was investigated based on the proposed model. The numerical model was firstly verified with the quasi-static analysis results and experimental data under dynamic condition, and then the contributions of different forces to the variations of line tension were evaluated. It is found that two factors (inertia force and soil resistance) have a great influence on the mooring line tension variation. The inertial effect is dominated under high-frequency condition, and the maximum line tension at the fairlead is larger than that under static condition. However, the tension at the pad-eye under dynamic condition always has a certain increase. The reason is that partial reverse soil resistance under dynamic condition increases the tension at the pad-eye.
Energy Saving Using Scenario Based Sensor Selection on Medical Shoes (2015)

Cost and energy have become the bottleneck of many medical embedded systems. It is mainly due to the fact that wireless medical devices used in wireless health applications normally employ a large number of sensors, which are both expensive as well as consuming a considerable amount of energy. In this paper, we have developed a cost and energy saving scheme by reducing the number of required sensors in the medical devices. We have used a popular medical shoe with 99 pressure sensors for demonstration. With the goal of reducing the number of required sensors without influencing the diagnose accuracy, we have proposed algorithms to select only a small subset of the sensors while still maintaining an almost same diagnostic performance compared to using all the 99 sensors. Our results indicate that on average, our sensor selection can save as much as 88% of the total sensors. We also analyze the effect of using the medical shoes under different scenarios on the results of sensor selection. For example, we have analyzed the scenarios of walking, jumping, running and slow walking. Based on our sensor selection algorithm, it turns out that there exists different subsets of sensors to best recover the diagnostic performances for different scenarios.

Nimesulide Improves the Symptomatic and Disease Modifying Effects of Leflunomide in Collagen Induced Arthritis (2014)

Nimesulide is a COX-2 inhibitor used for symptomatic relief of rheumatoid arthritis. Leflunomide is an anti-pyrimidine used to manage the progression of rheumatoid arthritis. Herein we studied the influence of nimesulide and leflunomide combination in terms of disease symptoms and progression using collagen-induced arthritis model in mice, as a model for rheumatoid arthritis. Collagen induced arthritis was induced by immunization with type II collagen. Assessment of joint stiffness and articular hyperalgesia were evaluated using a locomotor activity cage and the Hargreaves method, respectively. Disease progression was assessed via arthritic index scoring, X-ray imaging, myeloperoxidase enzyme activity and histopathologic examination. Nimesulide induced only transient symptomatic alleviation on the top of decreased leucocytic infiltration compared to arthritis group. However, nimesulide alone failed to induce any significant improvement in the radiological or pathological disease progression. Leflunomide alone moderately alleviates the symptoms of arthritis and moderately retarded the radiological and pathological disease progression. Combination of nimesulide and leflunomide significantly improved symptomatic (analgesia and joint stiffness) and arthritic disease progression (radiological, pathological and Myeloperoxidase enzyme activity) in collagen induced arthritis animal model.
Linear cyclic correlation approaches for blind identification of FIR channels (2002)

Blind fractionally spaced equalizers rely on output only samples taken at a rate higher than the symbol rate in order to estimate the channel taps. Simple methods for mixed phase FIR channel identification are developed by solving a linear system of equations formed by sample cyclic correlations of the received oversampled data sequence. In addition to computational simplicity over existing multivariate alternatives, the resulting linear algorithm is easily modified to yield asymptotically minimum variance weighted least squares channel estimators. A "deterministic" approach is also developed which requires only persistently exciting inputs and leads to closed form data based solutions. Comparisons and tools for performance analysis are also described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Phorbol-ester-induced Activation of the NF- B Transcription Factor Involves Dissociation of an Apparently Cytoplasmic NF- B/Inhibitor Complex (1988)

In eukaryotic cells, many genes respond in their rate of transcription to extracellular stimuli. Changes in gene expression in response to such agents as steroid hormones, growth factors, interferon, tumor promoters, heavy metal ions, and heat shock were shown to be modulated through distinct cis-acting DNA-sequence elements (for review, see Hatzopoulos et al. 1988). The most important sequences are those called enhancers (for review, see Schlokat and Gruss 1986), which display great positional flexibility with respect to the gene they control (Banerji et al. 1981; Fromm and Berg 1983), and promoters, which are confined to the 5′-noncoding region of the gene (for review, see McKnight and Tjian 1986). Both cis-acting elements contain multiple binding sites for sequence-specific DNA-binding proteins (for review, see Hatzopoulos et al. 1988; Wingender 1988). The demonstration of DNA-protein interaction in vivo (Ephrussi et al. 1985), in vitro competition experiments (Schoeler and Gruss 1985), and the mutational...
Atrial Tachycardias Encountered in the Context of Catheter Ablation for Atrial Fibrillation Part II: Mapping and Ablation (2009)

Over the past decade, there has been an exponential increase in the number of catheter ablation procedures performed for atrial fibrillation (AF). While for paroxysmal AF, proximal pulmonary vein isolation is sufficient in the majority of cases, ablation of persistent and longstanding AF requires an extensive surgical-like procedure. This approach is correlated with a high rate of AF termination; however, this is achieved at the cost of at least one atrial tachycardia (AT) during the index procedure or during the patient's follow-up in the vast majority of cases. As these ATs are often multiple, complex, and frequently more symptomatic than AF, they constitute the last and frequently the most difficult step in ablation for patients with persistent AF. This review concentrates on the practical approaches to the treatment of AT in the context of AF ablation and provides an algorithm that aims at facilitating mapping and ablation strategies using conventional electrophysiological tools.
