Experimental identification of rigid body inertia properties using single-rotor unbalance excitation (2009)

This article proposes a new experimental method for the identification of rigid body inertia properties. The test structure is suspended in an elastic wire and excited by a single-rotor unbalance actuator. Unlike a conventional shaker or impulse actuator, the proposed actuator can be rigidly attached to the test structure, whereby accurate alignment is made relatively easy. Moreover, because of a sensorless single-rotor design, the actuator can be built at minimal cost. Both the excitation force and the rotation frequency required as feedback to control the actuator are derived from the structure's acceleration response signal; as a result, the experiment requires no sensors other than one accelerometer. The acceleration response measurements are used in an identification algorithm based on models of the unknown rigid body inertia properties and of the suspension properties. In the process of identifying the inertia properties, the suspension model prevents errors otherwise caused by suspension and gravity effects. The proposed method was applied to two test cases: a beam structure and an assembled motorcycle frame and engine. In both cases, accurate rigid body properties could be identified.
Rattlers or oxygen vacancies: Determinant of high temperature plateau thermal conductivity in doped pyrochlores (2013)

High temperature plateau thermal conductivity (kmin) remains poorly understood despite its crucial importance in thermal insulation components at elevated temperature. We report In/Sc doped La2Zr2O7 pyrochlores with rattlers and oxygen vacancies and their effects on heat transport. Rattlers can dramatically flatten k-T curves at very low doping level; whereas, oxygen vacancies are very effective in reducing kmin, particularly when comparing compounds with considerably varied levels of them. Oxygen vacancies generate an electrostatic repulsion force among cations surrounding them, resulting in stronger lattice anharmonicity and weaker bonds, which is the underlying reason of them being the determinant of kmin.
A Staff Dialogue on Phase I Trials: Psychosocial Issues Faced by Patients, Their Families, and Caregivers (1998)

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital, founded The Kenneth B. Schwartz Center to be housed at Massachusetts General Hospital (MGH). He created this center to advance the hopes, goals, and ideas expressed in his article, “A Patient's Story,” published in the July 16, 1995 issue of the Boston Globe Magazine. The Schwartz Center is a non-profit organization dedicated to strengthening the relationship between patients and caregivers and to supporting and advancing “compassionate health care delivery in which caregivers, patients and their families relate meaningfully to one another in a way that provides hope to the patient, support to caregivers and sustenance to the healing process.” One of the Center's major projects is the sponsoring of the Schwartz Center Rounds, a monthly, multidisciplinary forum in which caregivers discuss a specific cancer patient and the important psychosocial issues faced by the patient, family and caregivers. The forum allows caregivers to reflect on their experiences with patients and to gain support and insight from fellow staff members. Kenneth B. Schwartz The following case discussion was addressed at the January 1998 Schwartz Center Rounds. In this article, the case will be presented, followed by verbatim dialogue from the rounds and a subsequent discussion of the relevant issues with emphasis on staff psychosocial issues. J.T. was a 43-year-old man who developed adenocarcinoma of the lung and was treated at MGH. He died while participating in a phase I trial, resulting in marked frustration and distress among his caregivers. Staff questioned whether cancer patients entering phase I trials and their families receive unbiased information about the possible risks and benefits of the trial. They were also concerned about whether or not patients and their families really understand the physical and emotional risks of a trial. Moreover, they addressed whether patients are presented with alternatives to enrolling in a phase I trial, such as palliative care. Despite all these concerns, caregivers are reconciled to the belief that patients do value the opportunity to participate in phase I trials, in that they can contribute hope and meaning to other patients' struggles with cancer.
Evaluation of Management of Pig Farms Using Balance Score Card (2020)

Korean hog farms have been scaled up in the past decade. Even though, hog farms measure the management performance with just productivity or profitability. There is an evaluation system that gives positive effect on business performance by using both financial and non-financial evaluation indices. This study selects Key Performance Indicators (KPI) suitable for hog farms based on Kaplan & Norton s Balance Score Card (BSC). Using the Structural Equation Model (SEM), we analyze the relationships between financial and non financial perspectives. The results show that the learning and growth perspective has a positive effect on customer perspective and internal business process perspective respectively. Internal business process perspective has a positive effect on customer perspective and financial perspective respectively. The learning and growth perspective has a positive effect on financial perspective indirectly via the internal business process.
Fast optical channel recovery in field demonstration of 100-Gbit/s Ethernet over OTN using real-time DSP (2011)

A field trial of 100-Gbit/s Ethernet over an optical transport network (OTN) is conducted using a real-time digital coherent signal processor. Error free operation with the Q-margin of 3.2 dB is confirmed at a 100 Gbit/s Ethernet analyzer by concatenating a low-density parity-check code with a OTN framer forward error correction, after 80-ch WDM transmission through 6 spans x 70 km of dispersion shifted fiber without inline-dispersion compensation. Also, the recovery time of 12 msec is observed in an optical route switching experiment, which is achieved through fast chromatic dispersion estimation functionality.
Suppression Method for Harmonic Magnification of DC Circuit in Large-Scale Inverter System (2005)

In a large-scale inverter system that uses a semiconductor switching device, a rectifier and an inverter are connected through a DC circuit. In this circuit, the harmonic magnification phenomenon is often induced by the inductance of distribution wires and the condenser to absorb the harmonic voltage and current. To suppress this harmonic magnification phenomenon, we propose a new suppression method to use the initial phase of the carrier wave. When some inverters operate in parallel at the same frequency, such as the inverters to drive LSM, it is possible to reduce the specific harmonic component of the total inverter input current due to PWM control by changing the phase of the carrier wave of each inverter. We studied a method of suppressing the magnification phenomenon of the specific harmonic near the resonant frequency of the DC circuit by using this principle and confirmed its performance by the digital simulation.
Phospholipase A 2 inhibitor–loaded micellar nanoparticles attenuate inflammation and mitigate osteoarthritis progression (2021)

Treating osteoarthritis (OA) remains a major clinical challenge. Despite recent advances in drug discovery and development, no disease-modifying drug for knee OA has emerged with any notable clinical success, in part, due to the lack of valid and responsive therapeutic targets and poor drug delivery within knee joints. In this work, we show that the amount of secretory phospholipase A<sub>2</sub> (sPLA<sub>2</sub>) enzyme increases in the articular cartilage in human and mouse OA cartilage tissues. We hypothesize that the inhibition of sPLA<sub>2</sub> activity may be an effective treatment strategy for OA. To develop an sPLA<sub>2</sub>-responsive and nanoparticle (NP)-based interventional platform for OA management, we incorporated an sPLA<sub>2</sub> inhibitor (sPLA<sub>2</sub>i) into the phospholipid membrane of micelles. The engineered sPLA<sub>2</sub>i-loaded micellar NPs (sPLA<sub>2</sub>i-NPs) were able to penetrate deep into the cartilage matrix, prolong retention in the joint space, and mitigate OA progression. These findings suggest that sPLA<sub>2</sub>i-NPs can be promising therapeutic agents for OA treatment.
Poor prognosis for existing monitors in the intensive care unit (1997)

Efforts to develop intelligent monitoring systems have more potential to deliver significantly improved patient care by initially targeting especially weak areas in ICU monitoring, such as pulse oximetry reliability.
A Comparison of Two Zinc Hydride Catalysts for Terminal Alkyne C–H Borylation/Hydroboration and the Formation of 1,1,1-Triborylalkanes by Tandem Catalysis Using Zn–H and B–H Compounds (2020)

The synthesis of 1,1,1-triborylalkanes from terminal alkynes and pinacolborane (HBPin) is reported. This transformation proceeds via initial Zn-catalyzed alkyne C–H borylation, which can be achieved using a NacNacZnH complex. Combinations of a NacNacZn-alkynyl formed via C–H zincation of a terminal alkyne and HBPin exist in equilibrium with the alkynyl-BPin and NacNacZnH. The consumption of NacNacZnH by irreversible reaction with a terminal alkyne evolving H2 is essential for driving alkyne C–H borylation to completion. The alkynyl-BPin compounds undergo hydroboration catalyzed by Zn–H complexes at raised temperatures with a {7DIPP}ZnH(NTf2) complex (7DIPP = 1,3-bis(2,6-diisopropylphenyl)-4,5,6,7-tetrahydro-1H-1,3-diazepin-3-ium-2-ide) a more active catalyst for hydroboration than a NacNacZnH complex. Calculations indicate the {7DIPP}Zn–H congener has a more pronounced biphilic character than that of NacNacZnH (greater electrophilicity at Zn while maintaining a basic hydride). Of the two hydroboration steps, the hydroboration of alkynylBPin is catalyzed by Zn–H complexes, while the hydroboration of 1,1-diborylalkenes is catalyzed more effectively by B–H-containing species, including boranes formed in situ from HBPin. These observations led to a one-pot protocol being developed for converting terminal alkynes into 1,1,1-triborylalkanes that utilizes {7DIPP}ZnPh(NTf2) as a precatalyst for the formation of 1,1-diborylated alkenes with subsequent addition of BH3-THF as catalyst for the final step.
Joint Source/Channel Coding for JPEG2000 Codestream Transmission over Fading Channels (2006)

The embedded codestream structures and a variety of progressive image compression methods provided by JPEG2000 make it attractive for image transmission purposes. A three-level, hybrid optimization scheme is proposed for JPEG2000 compressed images over a correlated block fading channel with a cyclic redundancy check code (CRC) and a rate-compatible punctured convolution (RCPC) code. It combines forward error correction (FEC) and JPEG2000 error resilience (ER) mechanisms to minimize the end-to-end image distortion according to channel conditions. The proposed scheme employed a finite-state Markov channel model to simulate the channel. It has the complexity less than O (R <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) for a special JPEG2000 codestream, where R is the number of available channel code rates. Simulation results show a significant improvement about 0.7-1.3 dB over the based two-level scheme in quality of received images
Temperature effects on emission of quantum dots embedded in polymethylmethacrylate (2010)

We successfully used CdSe/ZnS quantum dots (QDs) as a dopant within a polymethylmethacrylate (PMMA) matrix. This doped material was used in the fabrication of a microstructured polymer optical fiber whose photoluminescence was characterized. A detailed analysis of the emission properties of the QDs as a function of temperature is presented, with the temperature dependence of this emission broken into components to show contributions from the thermo-optic effect of the PMMA and the temperature-dependence of the bandgap of the QDs.
Swimming Microrobot Optical Nanoscopy (2016)

Optical imaging plays a fundamental role in science and technology but is limited by the ability of lenses to resolve small features below the fundamental diffraction limit. A variety of nanophotonic devices, such as metamaterial superlenses and hyperlenses, as well as microsphere lenses, have been proposed recently for subdiffraction imaging. The implementation of these micro/nanostructured lenses as practical and efficient imaging approaches requires locomotive capabilities to probe specific sites and scan large areas. However, directed motion of nanoscale objects in liquids must overcome low Reynolds number viscous flow and Brownian fluctuations, which impede stable and controllable scanning. Here we introduce a new imaging method, named swimming microrobot optical nanoscopy, based on untethered chemically powered microrobots as autonomous probes for subdiffraction optical scanning and imaging. The microrobots are made of high-refractive-index microsphere lenses and powered by local catalytic reactions to swim and scan over the sample surface. Autonomous motion and magnetic guidance of microrobots enable large-area, parallel and nondestructive scanning with subdiffraction resolution, as illustrated using soft biological samples such as neuron axons, protein microtubulin, and DNA nanotubes. Incorporating such imaging capacities in emerging nanorobotics technology represents a major step toward ubiquitous nanoscopy and smart nanorobots for spectroscopy and imaging.
Towards The Creation Of The Future Fish Farm (2023)

A fish farm is an area where fish raise and bred for food. Fish farm environments support the care and management of seafood within a controlled environment. Over the past few decades, there has been a remarkable increase in the calorie intake of protein attributed to seafood. Along with this, there are significant opportunities within the fish farming industry for economic development. Determining the fish diseases, monitoring the aquatic organisms, and examining the imbalance in the water element are some key factors that require precise observation to determine the accuracy of the acquired data. Similarly, due to the rapid expansion of aquaculture, new technologies are constantly being implemented in this sector to enhance efficiency. However, the existing approaches have often failed to provide an efficient method of farming fish. This work has kept aside the traditional approaches and opened up new dimensions to perform accurate analysis by adopting a distributed ledger technology. Our work analyses the current state-of-the-art of fish farming and proposes a fish farm ecosystem that relies on a private-by-design architecture based on the Hyperledger Fabric private-permissioned distributed ledger technology. The proposed method puts forward accurate and secure storage of the retrieved data from multiple sensors across the ecosystem so that the adhering entities can exercise their decision based on the acquired data. This study demonstrates a proof-of-concept to signify the efficiency and usability of the future fish farm.
Reader emotion classification of news headlines (2009)

Emotion classification of text is very important in applications like emotional text-to-speech (TTS) synthesis, human computer interaction, etc. Past studies on emotion classification focus on the writer's emotional state conveyed through the text. This research addresses the reader's emotions provoked by the text. The classification of documents into reader emotion categories has novel applications. One of them is to integrate reader emotion classification into a Web search engine to allow users to retrieve documents that contain relevant contents and at the same time produce proper emotions. Another is for Web sites to organize contents according to reader emotion categories and provide users a convenient browse. In this paper, we explore sentence level emotion classification. Firstly, we extract news headlines and related reader emotion information from the Web. Then we classify news headlines into reader emotion categories using support vector machine (SVM), and examine classification performance under different feature settings. Experiments show that certain feature combinations achieve good results.
Synthesis of robust delay-fault-testable circuits: theory (1992)

The authors give a comprehensive theoretical framework for the analysis and synthesis of delay-fault-testable combinational logic circuits. For each of the common models of delay-fault testability, robust gate-delay faults and robust path-delay faults, they provide the necessary and sufficient conditions for complete testability under that model for two-level circuits. The authors describe the conditions in terminology common to two-level minimization and show their relationship to properties produced by two-level minimizers. Similar conditions for multilevel networks are presented. It is shown that constrained algebraic factorization is required to retain complete gate-delay-fault testability beginning from a two-level network. The authors present preliminary experimental results using these synthesis techniques.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
The ANTHEM representation formalism for the alphabetic index of ICD. (1995)

This paper describes a formalism in which the knowledge of the Alphabetic Index of ICD is expressed unambiguously in the ANTHEM prototype. The Alphabetic Index may be viewed as a collection of hypotheses on which ICD-codes should be tried first for a given diagnostic expression. The hypotheses generation can be based upon characteristics of the semantic representation of the diagnostic expression. The formalism is described using an "operational" semantics by referring to the processes that have to operate on the expressions in the knowledge base. A close integration between a sound linguistic model of diagnostic expressions and the formalism itself is realized.
Quiet New Particle Formation in the Atmosphere (2022)

Atmospheric new particle formation (NPF) has been observed to take place in practice all around the world. In continental locations, typically about 10–40% of the days are so-called NPF event days characterized by a clear particle formation and growth that continue for several hours, occurring mostly during daytime. The other days are either non-event days, or days for which it is difficult to decide whether NPF had occurred or not. Using measurement data from several locations (Hyytiälä, Järvselja, and near-city background and city center of Budapest), we were able to show that NPF tends to occur also on the days traditionally characterized as non-event days. One explanation is the instrument sensitivity towards low number concentrations in the sub-10 nm range, which usually limits our capability to detect such NPF events. We found that during such days, particle formation rates at 6 nm were about 2–20% of those observed during the traditional NPF event days. Growth rates of the newly formed particles were very similar between the traditional NPF event and non-event days. This previously overlooked phenomenon, termed as quiet NPF, contributes significantly to the production of secondary particles in the atmosphere.
Sensitivity Analysis of the QT and JTpeak Intervals from a High-resolution Human Left-ventricular Wedge Model (2017)

There is an interest in looking at sub-intervals of the QT in the Comprehensive in-vitro Proarrhythmia Assay (CiPA) initiative. Here, we performed a sensitivity analysis of JTpeak and T-wave morphology (TWM) parameters computed on transmural ECGs, generated by a highresolution human left-ventricular wedge model, with a modified version of the ten Tusscher 2006 cardiac cell model, with respect to the block of the slow and rapid potassium channels (IKs and IKr), and the late sodium channel (NaL), from 0% to 90%. Moreover, we simulated the effects of Dofitilide and Ranolazine. TWM parameters were QT interval (QT), T-peak to T-end (TpTe), T amplitude (Tamp), J to T-peak (JTpeak), Flatness Score (FS), Asymmetry Score (AS), average APD90 (APD90avg), APD Dispersion (APD90Disp) and standard deviation of the repolarization times (s ). Sensitivities were computed as the percentage variation normalized at 50% block and they varied across ion channels and amount of block. QT interval, JTpeak and APD90avg performed similarly across channels (0.29). TpTe and s provided similar sensitivities (0.80 for both IKr and NaL, and 0.13 for IKs). AS resulted with the highest sensitivity to NaL block (8.35). Morover, the wedge model was capable to simulate the effects of the drugs. In conclusion, TWM parameters reflected ion channel alterations with different proportions.
Joint Minimum DL-UL Rate Maximization for Cell-Free Massive MIMO (2021)

In cell-free massive multiple-input multiple-output (MIMO) systems, the beamforming strategies at the base stations (BSs) and user equipments (UEs) can be computed building on bi-directional training. However, the precoding/decoding optimization in the downlink (DL) and in the uplink (UL) generally requires two separate bi-directional training phases, which can be wasteful in the case of short scheduling blocks. This paper proposes a framework to reduce the bi-directional training overhead by considering a common beamforming training strategy for both DL and UL when the UEs to be served in the two directions are the same. In doing so, we consider the problem of maximizing the (weighted) minimum DL-UL rate among all the UEs. Numerical results show that, in scenarios with short scheduling blocks, the proposed framework outperforms the case where the DL and UL beamforming strategies are computed individually via two separate bi-directional training phases thanks to the reduced training overhead. Even more substantial gains are observed with respect to the case with a single bi-directional training phase, where the DL (resp. UL) beamforming strategies are reused in the UL (resp. DL).
On design methods for sampled-data systems (2005)

In this paper we compare, via example, the standard approaches to sampled-data design with recently developed direct design methods for these hybrid systems. Simple intuitive examples are used to show that traditional design heuristics provide no performance guarantees whatsoever. Even when the sampling rate is a design parameter that can be chosen as fast as desired, using design heuristics can lead to either severe performance degradation or extreme over-design. These effects are apparently well-known to practitioners, but may not be widely appreciated by the control community at large. The paper contains no new theoretical results and is intended to be of a tutorial nature.
