A Novel Iterative Inter-Radar Interference Reduction Scheme for Densely Deployed Automotive FMCW Radars (2018)

Inter-radar interference will be a crucial problem when automotive FMCW radars are densely deployed for advanced driver assistance systems and automated driving cars. This paper proposes a novel iterative inter-radar interference reduction scheme to suppress inter-radar interference from multiple FMCW radars with various received level and chirp rate and shows performance evaluation results by computer simulation to validate the proposed scheme.
Low-frequency magnetic field detection with a magnetostrictive amorphous metal ribbon (1987)

A low-frequency magnetometer has been constructed by interfacing a transversely field-annealed amorphous metal ribbon to a resonating piezoelectric ceramic plate. Power spectrum measurements from 20 mHz to 1.0 Hz demonstrate a minimum detectable field of 8.7 pT/√Hz at 1.0 Hz with an approximate 1/f rise in the noise floor.
14.7 A 288µW programmable deep-learning processor with 270KB on-chip weight storage using non-uniform memory hierarchy for mobile intelligence (2017)

Deep learning has proven to be a powerful tool for a wide range of applications, such as speech recognition and object detection, among others. Recently there has been increased interest in deep learning for mobile IoT [1] to enable intelligence at the edge and shield the cloud from a deluge of data by only forwarding meaningful events. This hierarchical intelligence thereby enhances radio bandwidth and power efficiency by trading-off computation and communication at edge devices. Since many mobile applications are “always-on” (e.g., voice commands), low power is a critical design constraint. However, prior works have focused on high performance reconfigurable processors [2-3] optimized for large-scale deep neural networks (DNNs) that consume >50mW. Off-chip weight storage in DRAM is also common in the prior works [2-3], which implies significant additional power consumption due to intensive off-chip data movement.
Leptosphaeria biglobosa inhibits the production of sirodesmin PL by L. maculans (2022)

For the first time, L. biglobosa has been shown to inhibit the production of sirodesmin PL by L. maculans when interacting simultaneously with L. maculans either in vitro or in planta. This antagonistic effect of interspecific interaction may affect their coexistence and subsequent disease progression and management. © 2022 The Authors.

Physical attraction of Th9 cells is skin deep. (2015)

IL-9 was first identified as a growth factor for T cells and mast cells, and as an IL-2 cytokine family member with effects on hematopoietic progenitor cells and immune cells. The production of IL-9 by Th2 cells and by mast cells led to exploration of the role of IL-9 in allergic responses and parasite defense [see (1,2) for review]. Recent studies have resulted in identification of Th9 cells, a subset of CD4 Th cells that produce IL-9 and appear to be distinct from other CD4 T cell subsets (3,4). Thus, the identification of Th9 cells expanded the panel of CD4 Th subsets already including Th1, Th2, Th17, follicular helper T cells and regulatory T cells.
Extrinsic p-type doping of CuInSe/sub 2/ (1984)

Extrinsic p-type doping of CuInSe/sub 2/ crystals with phosphorous diffusion is demonstrated for the first time. The extrinsic doping experiments were performed by annealing the sample at 900/sup 0/C in a sealed tube under 0.01 atmosphere phosphorous vapor. The carrier concentration and the Hall mobility of the n-type as-grown CuInSe/sub 2/ crystals are 1.1 x 10/sup 17/ cm/sup -3/ and 954 cm/sup 2//V-s, respectively, and the n- to p-type conversion due to phosphorous diffusion results in the carrier concentration of 2.1 x 10/sup 17/ cm/sup -3/ and mobility of 9.1 cm/sup 2//V-s. The fabrication of a p-n junction on n-type CuInSe/sub 2/ crystals by extrinsic doping is explored. Preliminary results show that a p on n CuInSe/sub 2/ junction can be formed by this extrinsic doping process. Further extrinsic doping experiments on CuInSe/sub 2/ in both single crystals and thin films using other group V elements as acceptors by gas phase doping are proposed.
1H NMR-based metabolomic analysis of urine from preterm and term neonates (2011)

Metabolomics is a technique used to non-invasively determine metabolic status of an organism. Aim of our study was to analyze urinary metabolic profiles in term and preterm infants in order to identify gestational age-related metabolic differences and to predict metabolic maturity at birth. Twenty-six healthy term infants and 41 preterm infants were prospectively enrolled. A urine sample was collected non-invasively within the first hours of life. Samples were analyzed by proton nuclear magnetic resonance (1H NMR) spectroscopy and NMR urine spectra were analyzed by multivariate statistical analysis. Distinct metabolic patterns were found between term infants and preterm infants, as well as between preterm infants of 23-32 weeks' gestation and those of 33-36 weeks' gestation. Individual metabolites discriminating between these groups were hippurate, tryptophan, phenylalanine, malate, tyrosine, hydroxybutyrate, N-acetyl-glutamate, and proline. Metabolomic analysis revealed distinct urinary metabolic profiles in neonates of different gestational ages, and identified the discriminating metabolites. This holistic approach appears to be a promising tool for investigating newborn metabolic maturation over time, and might lead to a tailored management of neonatal disorders.
A resonant-clock 200MHz ARM926EJ-S<sup>TM</sup> microcontroller (2009)

An ARM926EJ-S <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TM</sup> microcontroller with a fully resonant clock distribution network and 16KB data and instruction caches has been implemented in 130nm bulk silicon. Workloads execute successfully across process and temperature corners, and at room temperature, typical-process chips run at clock speeds up to 200MHz with 1.2V supply. At resonance, the microcontroller core dissipates 0.23mW/MHz, recovering 85% of the energy in its clock distribution network. Total power savings range from 20% to 35%, depending on application workload and computation profile.
Amplitude spectrum based excitation model for HMM-based speech synthesis (2012)

This paper describes an excitation model based on amplitude spectrum for hidden Markov model (HMM)-based speech synthesis system (HTS). Residual signal obtained from inverse filtering is decomposed into periodic and aperiodic spectrums in frequency domain. Amplitude spectrum of half pitch period length is reserved as periodic component in synthesis stage and zero-phase criterion and pitch synchronous overlap add method (PSOLA) are adopted to reconstruct the residual signal. Before integrating this excitation model into HTS, these periodic spectrums are normalized and Linde-Buzo-Gray (LBG) algorithm is adopted to construct codebooks for every Mandarin final1. Then index parameters from these codebooks which are indicated as excitation information are taken into HTS training together with spectral, F0 and aperiodic parameters. Listening test showed that for female voice the analysis-synthesis result of the vocoder based on proposed excitation model is comparable with that of STRAIGHT and when integrating into HTS, the quality of generated speech is also improved.
The development of a solar powered residential heating and cooling system (1974)

A solar energy collector design is disclosed that would be efficient for both energy transfer and fluid flow, based upon extensive parametric analyses. Thermal design requirements are generated for the energy storage systems which utilizes sensible heat storage in water. Properly size system components (including the collector and storage) and a practical, efficient total system configuration are determined by means of computer simulation of system performance.
Method for Measuring the Properties of Liquid by a Single QCM at Different Temperatures (2018)

As an ultra-sensitive mass sensing device, quartz crystal microbalance (QCM) is widely used in gas phase and liquid phase. Previous research reported a novel theoretical model and a new method to separate measurement of density and viscosity of liquid only using a single QCM, based on the analysis of frequency response at room temperature. In this paper, current experimental results demonstrate the method for measuring properties of liquid by using a single QCM is valid at different temperatures.
Layered and Weighted Tree Matching Algorithm for Automatic Web Data Records Recognition (2013)

Automated web data record analysis and recognition is an important issue for improving the automation of web information extraction. Some typical methods perform similar data record analysis based on Simple Tree Matching (STM) algorithm. However, STM assigns elements the same weight and neglects the different impacts of different types of elements. Thus much noise would be induced during data record analysis, which eventually decreases the precision of data record recognition. This paper proposes a Layered and Weighted Tree Matching (LWTM) algorithm. First, we propose a layered filtering strategy to filter out potential noise elements. Then, we propose a weighted tree matching algorithm which assigns different weights for different types of HTML elements in terms of their importance for data record analysis. Further we combine the layered filtering strategy and the weighted tree matching algorithm to further improve the analysis results. Experimental results show that the proposed LWTM algorithm outperforms the STM-based methods.
Serum Iron:Ferritin Ratio Predicts Healthy Body Composition and Reduced Risk of Severe Fatty Liver in Young Adult Women (2017)

Dysregulated iron metabolism is associated with altered body composition and nonalcoholic fatty liver disease (NAFLD); however, mechanisms underlying this association remain undefined. We investigated this association in 117 women. Middle-aged women (≥45 years old (y)) were heavier and had lower serum iron, higher serum hepcidin, ferritin, and severe NAFLD incidence than young adult women (&lt;45 y). Age-adjusted linear regression analysis revealed that young adult women with the highest serum iron:ferritin ratio (Tertile 3) had a 5.08-unit increased percentage of muscle mass [β = 5.08 (1.48–8.68), p &lt; 0.001] and a 1.21-unit decreased percentage visceral fat mass [β = −1.21 (−2.03 to −0.39), p &lt; 0.001] compared with those with the lowest serum iron:ferritin ratio (Tertile 1; reference). The iron:ferritin dietary pattern, characterized by high consumption of beef, lamb, dairy products, fruits, and whole grains, and low consumption of refined carbohydrates (rice, noodles, and bread and pastries), and deep- and stir-fried foods, predicted a 90% [odds ratio: 0.10, 95% confidence interval: 0.02–0.47, p &lt; 0.001] reduced risk of mild vs. moderate and severe NAFLD in young adult women. Our findings suggest that the serum iron:ferritin ratio more accurately predicts body composition and reduced risk of severe fatty liver progression in young adult women compared to middle-aged women.
Predicting the Length of Stay in Neurosurgery with RuGPT-3 Language Model (2022)

In this study, we update the evaluation of the Russian GPT3 model presented in our previous paper in predicting the length of stay (LOS) in neurosurgery. We aimed to assess the performance the Russian GPT-3 (ruGPT-3) language model in LOS prediction using narrative medical records in neurosurgery compared to doctors' and patients' expectations. Doctors appeared to have the most realistic LOS expectations (MAE = 2.54), while the model's predictions (MAE = 3.53) were closest to the patients' (MAE = 3.47) but inferior to them (p = 0.011). A detailed analysis showed a solid quality of ruGPT-3 performance based on narrative clinical texts. Considering our previous findings obtained with recurrent neural networks and FastText vector representation, we estimate the new result as important but probably improveable.
Informatics in Radiology: Developing a Touchless User Interface for Intraoperative Image Control during Interventional Radiology Procedures (2012)

Review of prior and real-time patient images is critical during an interventional radiology procedure; however, it often poses the challenge of efficiently reviewing images while maintaining a sterile field. Although interventional radiologists can "scrub out" of the procedure, use sterile console covers, or verbally relay directions to an assistant, the ability of the interventionalist to directly control the images without having to touch the console could offer potential gains in terms of sterility, procedure efficiency, and radiation reduction. The authors investigated a potential solution with a low-cost, touch-free motion-tracking device that was originally designed as a video game controller. The device tracks a person's skeletal frame and its motions, a capacity that was adapted to allow manipulation of medical images by means of hand gestures. A custom software program called the Touchless Radiology Imaging Control System translates motion information obtained with the motion-tracking device into commands to review images on a workstation. To evaluate this system, 29 radiologists at the authors' institution were asked to perform a set of standardized tasks during a routine abdominal computed tomographic study. Participants evaluated the device for its efficacy as well as its possible advantages and disadvantages. The majority (69%) of those surveyed believed that the device could be useful in an interventional radiology practice and did not foresee problems with maintaining a sterile field. This proof-of-concept prototype and study demonstrate the potential utility of the motion-tracking device for enhancing imaging-guided treatment in the interventional radiology suite while maintaining a sterile field.

Recovery and purification of ionic liquids from solutions: a review (2018)

With low melting point, extremely low vapor pressure and non-flammability, ionic liquids have been attracting much attention from academic and industrial fields. Great efforts have been made to facilitate their applications in catalytic processes, extraction, desulfurization, gas separation, hydrogenation, electronic manufacturing, <i>etc.</i> To reduce the cost and environmental effects, different technologies have been proposed to recover the ionic liquids from different solutions after their application. This review is mainly focused on the recent advances of the recovery and purification of ionic liquids from solutions. Several methods for recovery of ionic liquids including distillation, extraction, adsorption, membrane separation, aqueous two-phase extraction, crystallization and external force field separation, are introduced and discussed systematically. Some industrial applications of ionic liquid recovery and purification methods are selected for discussion. Additionally, considerations on the combined design of different methods and process optimization have also been touched on to provide potential insights for future development of ionic liquid recovery and purification.
Glucuronidation of arachidonic and linoleic acid metabolites by human UDP-glucuronosyltransferases (2003)

Arachidonic acids (AA) and linoleic acids (LAs) are metabolized, in several tissues, to hydroxylated metabolites that are important mediators of many physiological and pathophysiological processes. The conjugation of leukotriene B4 (LTB4), 5-hydroxyeicosatetraenoic acid (HETE), 12-HETE, 15-HETE, and 13-hydroxyoctadecadienoic acid (HODE) by the human UDP-glucuronosyltransferase (UGT) enzymes was investigated. All substrates tested were efficiently conjugated by human liver microsomes to polar derivatives containing the glucuronyl moiety as assessed by mass spectrometry. The screening analyses with stably expressed UGT enzymes in HK293 showed that glucuronidation of LTB4 was observed with UGT1A1, UGT1A3, UGT1A8, and UGT2B7, whereas UGT1A1, UGT1A3, UGT1A4, and UGT1A9 also conjugated most of the HETEs and 13-HODE. LA and AA metabolites also appear to be good substrates for the UGT2B subfamily members, especially for UGT2B4 and UGT2B7 that conjugate all HETE and 13-HODE. Interestingly, UGT2B10 and UGT2B11, which are considered as orphan enzymes since no conjugation activity has so far been demonstrated with these enzymes, conjugated 12-HETE, 15-HETE, and 13-HODE. In summary, our data showed that several members of UGT1A and UGT2B families are capable of converting LA and AA metabolites into glucuronide derivatives, which is considered an irreversible step to inactivation and elimination of endogenous substances from the body.
Aerobic and anaerobic enrichment cultures highlight the pivotal role of facultative anaerobes in soil hydrocarbon degradation (2019)

Aliphatic and aromatic hydrocarbons are ubiquitous in the environment due to natural and anthropogenic processes. Under aerobic conditions hydrocarbons can be rapidly biodegraded but oxygenated environments often quickly become anaerobic when microbial respiration is coupled to contaminant oxidation. Most studies in literature usually focus on the initial microbial diversity of the hydrocarbon impacted environment and examine either aerobic or anaerobic conditions for enrichment. Hence, the aim of the present study was to enrich bacterial consortiums from two diesel impacted soil samples under both these conditions to assess the enrichment diversities and hydrocarbon degradation potentials. This would shed light upon how an environmental population shift would correlate to oxygen intrusion and depletion and still continue hydrocarbon degradation. Analysis of the 16S rRNA gene sequences showcases the different microbial populations that could emerge as the environmental factors change, resulting in different populations that are still capable of hydrocarbon degradation. Microbial diversity analysis also highlights the role of facultative anaerobic bacteria like Pseudomonas spp. and Citrobacter spp. in maintaining hydrocarbon degradation. This study shows that microorganisms capable of surviving under both oxic and anoxic (aerobic and anaerobic) conditions are the most crucial to the long term degradation of hydrocarbons in the environment.
Tumor-Derived Cell Culture Model for the Investigation of Meningioma Biology (2021)

Meningioma is the most common primary central nervous system tumor. Although mostly nonmalignant, meningioma can cause serious complications by mass effect and vasogenic edema. While surgery and radiation improve outcomes, not all cases can be treated due to eloquent location. Presently no medical treatment is available to slow meningioma growth owing to incomplete understanding of the underlying pathology, which in turn is due to the lack of high-fidelity tissue culture and animal models. We propose a simple and rapid method for the establishment of meningioma tumor-derived primary cultures. These cells can be maintained in culture for a limited time in serum-free media as spheres and form adherent cultures in the presence of 4% fetal calf serum. Many of the tissue samples show expression of the lineage marker PDG2S, which is typically retained in matched cultured cells, suggesting the presence of cells of arachnoid origin. Furthermore, nonarachnoid cells including vascular endothelial cells are also present in the cultures in addition to arachnoid cells, potentially providing a more accurate tumor cell microenvironment, and thus making the model more relevant for meningioma research and high-throughput drug screening.
Optically Transparent Polycrystalline Al 2 O 3 Produced by Spark Plasma Sintering (2007)

The spark plasma sintering (SPS) technique was used to produce mid‐infrared (IR) transparent alumina with the desired transmittance. An excellent transmittance of 85% has been obtained in a sample sintered at 1300°C for 5 min. The heating rate, sintering time, and annealing have a significant influence on IR transmittance. The improvement in transmission may be attributed to the progressive elimination of residual porosity when applying a slower heating rate, longer sintering time during SPS, and postsinter annealing. It is suggested that localized residual strain/stress at grain boundaries and oxygen vacancy concentration are other factors influencing the optical properties of the SPS‐sintered alumina.
Named data networking (2014)

Named Data Networking (NDN) is one of five projects funded by the U.S. National Science Foundation under its Future Internet Architecture Program. NDN has its roots in an earlier project, Content-Centric Networking (CCN), which Van Jacobson first publicly presented in 2006. The NDN project investigates Jacobson's proposed evolution from today's host-centric network architecture (IP) to a data-centric network architecture (NDN). This conceptually simple shift has far-reaching implications for how we design, develop, deploy, and use networks and applications. We describe the motivation and vision of this new architecture, and its basic components and operations. We also provide a snapshot of its current design, development status, and research challenges. More information about the project, including prototype implementations, publications, and annual reports, is available on named-data.net.
Tactile crescendos and sforzandos (2006)

Tactile icons (Tactons) are structured vibrotactile messages which can be used for non visual information display. Information is encoded in Tactons by manipulating vibrotactile parameters. This research investigates the possibilities of applying musical techniques to tactile icon design in order to define such parameters. Tactile versions of musical dynamics were created by manipulating the amplitude of vibrations to create increasing, decreasing, and level stimuli and an experiment was carried out to test perception of these stimuli. Identification rates of 92%-100% indicate that these tactile dynamics can be identified and distinguished from each other, and that tactile dynamics could be used in Tacton design.

Langerhans' cell histiocytosis (histiocytosis X) of bone a clinicopathologic analysis of 263 pediatric and adult cases (1995)

The clinical behavior of LCH of bone is often unpredictable; however, young age at diagnosis, hepatosplenomegaly, thrombocytopenia, and polyostotic (> or = 3 bones involved) disease are associated with a poor prognosis (P < 0.005). Recrudescence in children, but not in adults, strongly correlates with the presence of diabetes insipidus (P < 0.0005).
