Energy Harvesting Modulation for Integrated Control State and Energy Transfer in Industrial IoT (2022)

With the development of wireless communications, the technology of industrial Internet of Things (IIoT) has been considered as a candidate for the next generation of mobile communications, which could provide automatic services for the smart factory. Massive low-power devices are swarming into the scenario for providing network intelligence. These energy-thirsty devices all require efficient control state delivery. In this letter, an energy harvesting modulation (EHM) scheme is proposed for integrated control state and energy transfer (ICSET) towards these low-power devices. The performance of wireless energy transfer (WET) and wireless control state transfer (WCST) are also analysed theoretically. The ICSET performance is optimized by ensuring the control reliability. Simulation results validate the theoretical analysis. They also demonstrate that an appropriate time slot number within a period should be selected to increase the effective control rate, while ensuring the energy harvesting performance and the control reliability of IIoT.
Myocyte cell loss and myocyte cellular hyperplasia in the hypertrophied aging rat heart. (1990)

To determine the effects of age on the myocardium, the functional and structural characteristics of the heart were studied in rats at 4, 12, 20, and 29 months of age. Mean arterial pressure, left ventricular pressure and its first derivative (dP/dt), and heart rate were comparable in rat groups up to 20 months. During the interval from 20 to 29 months, elevated left ventricular end-diastolic pressure and decreased dP/dt indicated that a significant impairment of ventricular function occurred with senescence. In the period between 4 and 12 months, a reduction of nearly 19% in the total number of myocytes was measured in both ventricles. In the subsequent ages, similar decreases in myocyte cell number were found in the left ventricle, whereas in the right ventricle, the initial loss was fully reversed by 20 months. Moreover, from 20 to 29 months, a 59% increase in the aggregate number of myocytes occurred in the right ventricular myocardium. In the left ventricle, a 3% increment was also seen, but this small change was not statistically significant. These estimations of myocyte cellular hyperplasia, however, were complicated by the fact that cell loss continued to take place with age. The volume fraction of collagen in the tissue, in fact, progressively increased from 8% and 7% at 4 months to 16% and 22% at 29 months in the left and right ventricles, respectively. In conclusion, myocyte cellular hyperplasia tends to regenerate the ventricular mass being lost with age in the adult mammalian rat heart.
Spintronics Technology Solutions for Interferometric Thermal-Electromagnetic Sensing (2022)

Hybrid electromagnetic (EM) and thermal imaging using spintronic technologies is proposed for sensing circuits and systems in near-field and far-field from DC (Switching-Power) to mmWave frequencies. High resolution spintronic sensors capable of detecting magnetic fields ranging from few tens of mT (milli-Tesla) down to tens of pT (pico-Tesla) are demonstrated spanning about 10 orders of magnitude in dynamic range. A configurable Agile Front-End-Module LNA (AFEM) is combined with spintronics probe-array sensors providing adjustable 80 dB of dynamic range for subsequent processing of MIMO correlations in time and frequency domains. The proposed hybrid EM-Thermal sensing solution is applied to mmWave beamforming modules demonstrating the possibility of extracting power-density and energy-density metrics as a function of beamforming angles. An infrared (IR)-Visual dual-camera is introduced together with augmented reality (AR) based on 3D non-uniform spatial-sampling. Porting of chemically functionalized spintronic sensing materials into advanced FD-SOI platforms is proposed using advanced MRAM/SRAM process technologies.

Seismic MWD: Drilling in time, on time, it's about time (2005)

Since the dawn of logging-while-drilling (LWD) in the 1980s, the industry has wanted a reliable while-drilling borehole seismic measurement. However, a number of technical roadblocks prohibited its realization until recently. These difficulties included the nature and required accuracy of the measurement, timing issues, sensors, automation, and the lack of an electrical connection between the downhole tools and the surface in a while-drilling configuration.
Circulating microRNAs as markers for prediction of heart failure medical treatment outcome (2013)

Purpose: Chronic heart failure (HF) is a major worldwide health care problem. Despite significant improvement of mortality and morbidity with medical therapy, not all patients respond well to the treatment. This "lack of response" has not been adequately explored and currently no biomarker is available to indicate which patient will respond medical treatment non-responders. As circulating microRNAs have been described as potential biomarkers in various heart diseases, we explored the role circulating microRNAs as potential biomarkers of HF and as predictors of treatment outcome. Methods: MicroRNA arrays were performed from plasma of 9 healthy controls, 10 HF treatment Non-responders, and 10 HF treatment Responders at 6-month follow up. HF treatment "Non-responders" was defined as death, re-hospitalization for HF, and/or reduction of left ventricular end-systolic volume of <10% in 6 months despite standard HF medication therapy. Then we selected 15 microRNAs with significant changes for further validation by quantitative real-time PCR assays with the plasma samples from another 17 healthy controls, 13 Non-responders and 13 Responders at 6-month follow up. Finally, we determined the diagnostic accuracy of these candidate microRNAs. Results: Our results showed that 3 of 5 microRNAs previously reported in HF patients (miR -423-5p, -320a, -17, -92a, and -22) failed to predict the treatment outcome. We identified 7 fibrosis- and inflammation-related microRNAs (including miR -27b, -221, -222, -140-3p, -155, -29b, and -31) were altered in HF patients. More importantly, they were able to predict the HF patients as receiver operator characteristics (ROC) curve analysis demonstrated higher predictive power of these 7 microRNAs within the HF registry, when comparing to healthy controls (AUC >0.87, P<0.01). After 6-month treatment, the plasma levels of these 7 microRNAs were altered in the Responders (P<0.05) as their levels did not show any significant changes in Non-responders. Analyses from comparison of ROC (AUC>0.90 for Responder and AUC<0.55 for Responder at 6-month follow up, P<0.05) and the Wilcoxon matched pairs test (P<0.05) confirmed the ability of these 7 microRNAs to discriminate the treatment Non-responders and Responders [PCY1] Conclusion: We identified 7 microRNAs (miR -27b, -221, -222, -29b, -31, -140-3p, and -155) as the effective biomarkers for HF and they possess a high discriminatory ability to distinguish HF treatment Non-responders from Responders. Our studies suggest that these 7 microRNAs are putative effective biomarkers of HF and of predicting treatment Non-responders.

Gene expression studies of hepatitis virus-induced woodchuck hepatocellular carcinoma in correlation with human results (2007)

The lack of good molecular markers for diagnosis as well as treatment assessment has rendered the hepatocellular carcinoma (HCC) a major challenge in health care. In this study, woodchucks were used as an animal model for hepatitis virus-induced HCC, and gene expression studies were performed using a human oligonucleotide microarray. An analysis approach combing supervised significant analysis of microarray (SAM), prediction analysis of microarray (PAM), and unsupervised hierarchical cluster methodologies statistically determined 211 upregulated and 78 downregulated genes between liver cancer and non-cancer liver tissues, and demonstrated > or = 93% accuracy in classifying the tissue samples. RT-PCR results confirmed the differential expression of selected sequenced woodchuck genes (SAT, IDH3B, SCD) in the microarray. Our study showed that differentially expressed genes were involved in transcription, RNA splicing, translation, cell cycle, metabolism, protein folding and degradation, apoptosis, immune response, metal binding, etc. Interestingly, some genes were involved with signaling pathways such as Ras/MAPK (MAPKAP1), Src-dependent pathways (CSK), hedgehog signaling pathway (HHIP), while Wnt signaling pathway may not be dominant in woodchuck HCC as shown by the downregulation of beta-catenin (TNNB1) and the upregulation of CXXC4 and CSNK2B. Numerous genes found in this study were also differentially expressed in human HCC and many other human cancers including breast, prostate and lung cancers, etc., serving as tumor suppressors, promoters, prognostic markers or chemotherapy targets. In conclusion, this study has demonstrated the robustness of the data analysis and the potential of using human microarrays on woodchuck samples. In particular, some of the differentially expressed genes in the woodchuck HCC can be further explored for possible molecular imaging targets or biological markers in human HCC.
Imagining Artificial Intelligence Applications with People with Visual Disabilities using Tactile Ideation (2017)

There has been a surge in artificial intelligence (AI) technologies co-opted by or designed for people with visual disabilities. Researchers and engineers have pushed technical boundaries in areas such as computer vision, natural language processing, location inference, and wearable computing. But what do people with visual disabilities imagine as their own technological future? To explore this question, we developed and carried out tactile ideation workshops with participants in the UK and India. Our participants generated a large and diverse set of ideas, most focusing on ways to meet needs related to social interaction. In some cases, this was a matter of recognizing people. In other cases, they wanted to be able to participate in social situations without foregrounding their disability. It was striking that this finding was consistent across UK and India despite substantial cultural and infrastructural differences. In this paper, we describe a new technique for working with people with visual disabilities to imagine new technologies that are tuned to their needs and aspirations. Based on our experience with these workshops, we provide a set of social dimensions to consider in the design of new AI technologies: social participation, social navigation, social maintenance, and social independence. We offer these social dimensions as a starting point to forefront users' social needs and desires as a more deliberate consideration for assistive technology design.

Boundary Layer Ingestion Benefit of the D8 Transport Aircraft (2017)

This paper presents the experimental assessment of the aerodynamic benefit of boundary layer ingestion for an advanced design civil transport aircraft, the D8 "double bubble," carried out from 2010 to 2015 as part of a NASA Phase 2 Program. A back-to-back comparison of non-boundary layer ingesting and boundary layer ingesting versions of the D8 was conducted using 1:11-scale powered models in the NASA Langley 14- by 22-foot subsonic tunnel. The aerodynamic benefit of boundary layer ingestion, as quantified by the difference in mechanical flow power required with boundary layer ingestion relative to the non-boundary layer ingesting case, was measured using two different methods to be 8.6% at the simulated cruise condition when the same propulsors are used on the two configurations. The benefit is found to be insensitive to the various modeling and processing assumptions. A detailed error analysis shows that the benefit has an uncertainty fraction of 0.21 and a 95% confidence interval fraction of 0.035, thus giving high confidence to these results. This work represents the first measurement of boundary layer ingestion performance improvements for a realistic civil aircraft configuration and provides a proof-of-concept for the use of boundary layer ingestion to improve fuel efficiency of subsonic transports.
Online and in situ monitoring of environmental pollutants: electrochemical biosensing of cadmium (2000)

Online sensitive monitoring of gene expression is essential for understanding microbial life and microbial communities, especially under stress-inducing conditions, such as the presence of environmental pollutants. We describe here a novel use of promoter-based electrochemical biosensing for online and in situ monitoring of gene expression in response to pollutants. As a model system, we used a cadmium-responsive promoter from Escherichia coil fused to a promoterless lacZ gene, which was monitored using an electrochemical assay of beta-galactosidase activity. This whole-cell biosensor could detect, within minutes, nanomolar concentrations of cadmium in water, sea water and soil samples, and it can be used for continuous online and in situ monitoring.
Isolated central nervous system relapses in patients with high-risk neuroblastoma. Clinical presentation and prognosis: experience of the Polish Pediatric Solid Tumors Study Group. (2021)

Abstract Although isolated central nervous system (CNS) relapses are rare, they may become a serious clinical problem in intensively treated patients with high-risk neuroblastoma (NBL). The aim of the study is presentation, assessment of incidence and the clinical course of isolated CNS relapses. Retrospective analysis involved 848 NBL patients treated from 2001 to 2019 at 8 centers of the Polish Pediatric Solid Tumors Study Group (PPSTSG). Group characteristics at diagnosis, treatment and patterns of relapse were analyzed. Observation was completed in December 2020. We analyzed 286 high risk patients, including 16 infants. Isolated CNS relapse, defined as presence of a tumor in brain parenchyma or leptomeningeal involvement, was found in 13 patients (4.5%, 8.4% of all relapses), all of them were stage 4 at diagnosis. Isolated CNS relapses seem to be more common in young patients with stage 4 MYCN amplified NBL, and in this group they may occur early during the first line therapy. The only or the first one symptom may be bleeding into CNS, especially in younger children, even without clear relapse picture on imaging, or the relapse may be clinically asymptomatic and found on routine screening. Although incidence of isolated CNS relapses is not statistically significantly higher in patients after immunotherapy, their occurrence should be carefully monitored, especially in intensively treated infants, with potential disruption of brain-blood barrier.
Ambient- and low-temperature synchrotron x-ray diffraction study of BaFe2As2and CaFe2As2at high pressures up to 56 GPa (2011)

We report on high-pressure powder synchrotron x-ray diffraction studies on $M$Fe${}_{2}$As${}_{2}$ ($M$$=$Ba, Ca) over a range of temperatures and pressures up to about 56 GPa using a membrane diamond-anvil cell. Our data indicate a phase transition to a collapsed tetragonal phase in both compounds upon compression. The data at 300 K are measured in both pressure-increasing and -decreasing cycles. Our measurements show that at 300 K in the Ba compound, the transition occurs at 27 GPa, which is much higher than the transition pressure of 1.7 GPa in the Ca compound. At low temperature, we could obtain data only in the pressure-increasing cycle, therefore a precise transition pressure is not identified. At a low temperature of 33 K, the transition to the tetragonal phase in the Ba compound starts, upon compression, at about 29 GPa, which is much higher than the transition pressure of 0.3 GPa at 40 K as known in the case of the Ca compound. The much higher transition pressure in the Ba compound may be due to its larger unit-cell volume at ambient pressure. It is important to note that the transition in both compounds occurs when they are compressed to almost the same value of the unit-cell volume and attain similar ${c}_{t}/{a}_{t}$ ratios. We also show that the FeAs${}_{4}$ tetrahedra are much less compressible and more distorted in the collapsed tetragonal phase than their nearly regular shape in the ambient pressure phase. We present a detailed analysis of the pressure dependence of the structures as well as equations of state in these important BaFe${}_{2}$As${}_{2}$ and CaFe${}_{2}$As${}_{2}$ compounds.
Divergent selection for sprouting resistance in spring wheat (1995)

The development of sprouting‐resistant spring‐wheat ( Triticum aestivum L.) cultivars is a major breeding objective in many wheat‐producing regions. Sprouting resistance is thought to be associated with delayed maturity. The primary objective of this study was to measure the reciprocal effects of selection for sprouting resistance and maturity. Two experiments were conducted over a 3–4‐year period in Saskatoon, Canada. In the first experiment, two populations of hard red spring wheat were subjected to divergent selection (k = 10%) for maturity. In the second experiment, six populations derived from crosses between two sprouting‐resistant, late‐maturing, white‐grained cultivars (‘AUS1293’ and ‘AUS1408’) and three early maturing, red–grained cultivars (‘Park’, ‘PT516’ and ‘Roblin’), were subjected to divergent selection (k = 10%) for sprouting resistance. Selection for earliness reduced sprouting resistance in one population but had no effect in the second. For both populations, earlier maturity was associated with higher test weight but lower grain yield. In the second experiment, selection for increased sprouting resistance was effective, with realized heritabilities averaging 0.74. Increased sprouting resistance was associated with a slight delay (1–2.5 days) in time to spike emergence in four out of six populations, but had little effect on time to maturity in most populations. There was a trend towards redder grain in the sprouting‐resistant selections. The recovery of sprouting‐resistant, early maturing segregants was relatively low, averaging less than 10% over the six populations. In conclusion, selection for increased sprouting resistance can result in delayed maturity, but the magnitude of that delay will vary among populations.
Integrated Microelectromechanical Process and Circuit Technology (2002)

Abstract : Duke University in partnership with Carnegie Mellon University and the MCNC MEMS Technology Applications Center has performed a research effort to develop new technologies in the area of integrated microelectromechanical systems (MEMS). The research in Integrated Microelectromechanical Process and Circuit Technology (IMPACT) was organized and structured to promote key advancements in MEMS that leveraged state-of-the-art technologies. The goals of the program were based on the need to decouple circuit and process design activities, and thereby promote a common 'front-end' to MEMS design tools, as has been done in the integrated circuit arena. Specifically, the goal of IMPACT was to develop a circuit-level design capture and optimization tool set for MEMS technology having a beneficial impact comparable to that of physical-level schematic capture and layout tools developed for IC technology.
A Copper‐ and Phosphine‐Free Nickel(II)‐Catalyzed Method for C−H Bond Alkynylation of Benzothiazoles and Related Azoles (2018)

Abstract A phosphine‐free nickel(II)‐catalyzed method for the C(2)−H bond alkynylation of (benzo)thiazoles, (benz)imidazoles, and oxazoles is described. Well‐defined and air‐stable (Phen)NiCl 2 catalyst efficiently catalyzes the coupling of diverse azoles with alkynyl bromides without the use of a copper co‐catalyst, and the method tolerates synthetically important functional groups. Preliminary mechanistic studies on this Ni II ‐catalyzed alkynylation emphasize the homogeneous nature of the catalyst, and rule out a radical manifold for the reaction. The synthetic utility of this Ni‐catalyzed method is demonstrated by further functionalizing the alkynylated benzothiazoles to 3‐methyl‐2‐(alkynyl)benzo[ d ]thiazolium salts that are known DNA cleaving agents.

LEO Satellite Constellations for 5G and Beyond: How Will They Reshape Vertical Domains? (2021)

The rapid development of communication technologies in the past decades has provided immense vertical opportunities for individuals and enterprises. However, conventional terrestrial cellular networks have unfortunately neglected the huge geographical digital divide, <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</sup> ince high-bandwidth wireless coverage is concentrated in urban areas. To meet the goal of “connecting the unconnected,” integrating low Earth orbit (LEO) satellites with the terrestrial cellular networks has been widely considered as a promising solution. In this article, we first introduce the development roadmap of LEO <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sa</sup> tellite constellations (SatCons), including early attempts in LEO satellites with the emerging LEO constellations. Further, we discuss the unique opportunities of employing LEO SatCons for the delivery of integrating 5G networks. Specifically, we present their key performance indicators, which offer important guidelines for the design of associated enabling techniques, and then discuss the potential impact of integrating LEO SatCons with typical 5G use cases, where we engrave our vision of various vertical domains reshaped by LEO SatCons. Technical challenges are finally provided to specify future research directions.

Theory of Pairing Vibrations (1970)

The bootstrap theory is applied to the case of pairing vibrations; an approximation used by Dang and Klein in their treatment of pairing is shown to be consistent with the bootstrap theory. A modified Tamm-Dancoff approximation is described. The numerical results for ${\mathrm{Ni}}^{58,60,62}$ are compared with the exact solutions and with the results of Dang and Klein.
