<title>Detection, location, and identification of building occupants using a robot-mounted through-wall radar</title> (2000)

We have assembled, programmed, and demonstrated a robot- mounted motion-detection radar suitable for through-wall operation. Our radar, which employs pulse-Doppler techniques, is designed to look through building walls and locate moving targets. The radar's signal-processing algorithms use both time-domain and frequency-domain clues to classify detected motion as arising from: (1) the ambient background; (2) mechanical motion; or (3) human activity. In the case of human motion, our routines also attempt to identify the occupant's particular activity, e.g., resting, walking, talking.

Real-time transcription system for simultaneous subtitling of Japanese broadcast news programs (2000)

There are strong demands to expand captioned broadcasting for TV news programs in Japan. However, keyboard entry of captioned manuscripts for news programs cannot keep pace with the speed of speech because Japanese use ideographic characters. To realize simultaneous subtitling of Japanese news programs, a real-time speech recognition system to handle broadcast news transcription has been developed. Experiments showed that word recognition error rate of the system for studio announcer speech is 2.8% in the real-time recognition and the error rate can reduce to 0.8% by manual correction with an average total delay of 10.4 seconds.
On Automated Trust Computation in IoT with Multiple Attributes and Subjective Logic (2020)

Developing automated trust mechanisms has become crucial for overcoming perceptions of uncertainty and risk by people using IoT services. Things are increasingly communicating with each other and trust in the data they deliver depends on several factors such as the links they use to communicate and the environment. This points to a need for a trust management method for "things" that considers the communication among them, environmental and security-related factors, and the net-work topology but without human intervention. To address these challenges, we propose a trust management framework that automatically computes the trust of "things". We use Multi-Attribute Decision Making (MADM) and Evidence-Based Subjective Logic (EBSL) in a trust network of "things" to take into account the uncertainty in trust values. We propose new normalization for non-monotonic attributes in MADM. We present an algorithm for automatic trust computation and evaluate its effectiveness using synthetic data and sampling from real datasets.
Novel zero-voltage and zero-current-switching (ZVZCS) full bridge PWM converter using transformer auxiliary winding (2002)

A novel zero voltage and zero current switching (ZVZCS) full bridge (FB) PWM converter is proposed to improve the demerits of the previously presented ZVZCS-FB-PWM converters such as use of lossy components or additional active switches. A simple auxiliary circuit which includes neither lossy components nor active switches provides ZVZCS conditions to primary switches, ZVS for leading-leg switches and ZCS for lagging-leg switches. Many advantages including simple circuit topology, high efficiency, and low cost make the new converter attractive for high power (>1 kW) applications. The operation, analysis, features and design considerations are illustrated and verified on a 2.5 kW, 100 kHz IGBT based experimental circuit.
Embedded Si Fan Out: A Low Cost Wafer Level Packaging Technology without Molding and De-Bonding Processes (2017)

Advanced packaging technology plays more and more important role for device miniaturization, system integration, and performance enhancement. Among many new packaging technologies, fan-out wafer level packaging (FOWLP) aroused more interests and showed the advantages of higher number of I/Os, integration flexibilities, low cost, and small form factor due to the elimination of substrate. However, FOWLP using epoxy mold compound (EMC) material faces a number of technical challenges such as warpage wafer handling, difficult to fabricate fine-pitch redistribution layer (RDL), and reliability issues for large package due to the CTE mismatch between chip and EMC. In addition, for high performance SiP, advanced FOWLP with multilayer fine-pitch RDLs, excellent alignment accuracy, shortest interconnect routing between dies, and ultra small form factor was required. In this paper, the development of a wafer level embedded silicon fan-out, named eSiFO technology was reported. For eSiFO package, the known good dies are embedded in the cavities formed on silicon wafer and the micro-scale gap between the dies and cavities is filled by epoxy material. An almost entire silicon surface was constructed as the fan-out area for RDL and BGA. The process is simple comparing with standard FOWLP since there is no molding, temporary bonding and de-bonding process. The key advantage is that the CTE for dies and silicon wafer is same and there is no warpage issue during manufacturing which results in good packaging yield. An eSiFO package with size of 3.3×3.3mm, one layer RDL and 50 BGAs was successfully demonstrated. The results proved that the process of eSiFO was simple and suitable for high density system integration with ultra low profile. Various reliability tests were carried out to study the package reliability and no failure was found. The simulation results show that for the same package, eSiFO has lower thermal stress than FOWLP using EMC.
Properties of terpenyl polyurethane acrylate resin through UV-thermal dual curing (2014)

Photo-heat dual curable terpenyl polyurethane acrylate resins were prepared by terpenyl hydroxy polyester and prepolymer of isophorone diisocyanate( IPDI) with pentaerythritol triacrylate( PETA). Molecular structures were identified by Fourier transform infrared spectrum( FT-IR),and thermal stabilities were characterized by the thermogravimetric analysis( TGA). The effects of UV curing time,thermal curing temperature and film thickness on gel content were investigated. Results indicated that properties of photo-heat curing films were superior to that of photo curing films except the flexibility,the pencil hardness increased from F to 2H,the adhesion increased from 2 degree to 0 degree. The solvent resistance and mechanical properties could be improved at different degrees. Terpene maleic anhydride( TMA) increased the thermal stability of the films.
Extraction of Propionic Acid Using Different Extractants (Tri-<i>n</i>-butylphosphate, Tri-<i>n</i>-octylamine, and Aliquat 336) (2008)

Reactive extraction of propionic acid from aqueous solution containing 0.05 to 0.4 kmol/m3 acid using tri-n-butylphosphate (TBP) (organophosphorous compound), tri-n-octylamine (TOA) (tertiary amine), and Aliquat 336 (quaternary amine) as extractants in 1-octanol was studied. The comparison among the different categories of extractants was made. The order of extraction power was found to be TOA > Aliquat 336 > TBP with KE values of 25.67, 3.58, and 2.36 m3/kmol, respectively. The highest value of equilibrium complexation constant (25.67 m3/kmol) and distribution coefficient (14.09) of TOA suggested it to be the best extractant among the three. The greatest support to highest recovery was also due to the choice of diluent for the system. 1-Octanol was an active diluent which provided good solvation of the acid-extractant complexes. In all the extractions (1:1) acid-extractant complexes were formed with loading ratios less than 0.5, except in Aliquat where values higher than 0.5 were also obtained. This led to the definition of an another equilibrium constant (KE(2:1)) as (2:1) acid−Aliquat complexes were formed, with the value of KE(2:1) = 26.54 (m3/kmol)2.

Single-Walled Carbon Nanotubes Enhance the Efficiency and Stability of Mesoscopic Perovskite Solar Cells (2017)

Carbon nanotubes are 1D nanocarbons with excellent properties and have been extensively used in various electronic and optoelectronic device applications including solar cells. Herein, we report a significant enhancement in the efficiency and stability of perovskite solar cells (PSCs) by employing single-walled carbon nanotubes (SWCNTs) in the mesoporous photoelectrode. It was found that SWCNTs provide both rapid electron transfer and advantageously shifts the conduction band minimum of the TiO<sub>2</sub> photoelectrode and thus enhances all photovoltaic parameters of PSCs. The TiO<sub>2</sub>-SWCNTs photoelectrode based PSC device exhibited a power conversion efficiency (PCE) of up to 16.11%, while the device fabricated without SWCNTs displayed an efficiency of 13.53%. More importantly, we found that the SWCNTs in the TiO<sub>2</sub> nanoparticles (TiO<sub>2</sub> NPs) based photoelectrode suppress the hysteresis behavior and significantly enhance both the light and long-term storage stability of the PSC devices. The present work provides important guidance for future investigations in utilizing carbonaceous materials for solar cells.
Improvised 3-0 Polypropylene Plug for the Glaucoma Drainage Tube During Phacoemulsification (2008)

Overfiltration through a preexisting glaucoma drainage tube can make subsequent phacoemulsification surgery more challenging due to a dangerously shallow anterior chamber. The author improvised a 3-0 polypropylene plug to occlude the implant tube during phacoemulsification in two patients with uveitic glaucoma and a prior Baerveldt glaucoma drainage device. The improvised plug safely and effectively maintained the anterior chamber during phacoemulsification. A 3-0 polypropylene suture can be tied, trimmed, and inserted into a glaucoma drainage implant tube, in select cases, to maintain the anterior chamber during cataract surgery.
Liver transplantation using uncontrolled non–heart-beating donors under normothermic extracorporeal membrane oxygenation (2009)

Because of the organ shortage, non-heart-beating donors have been proposed as a possible source of grafts for orthotopic liver transplantation (OLT). Despite the widespread use of controlled non-heart-beating donors, there are only a few published studies reporting the outcomes with uncontrolled non-heart-beating donors (UNHBDs). A prospective case-control study on adult patients undergoing OLT was designed. We used normothermic extracorporeal membrane oxygenation (NECMO) in all UNHBDs. Matching 2:1 ratio comparison was performed between a study group (UNHBDs) and a brain death donor (BDD) control group. Between January 2006 and March 2008, a total of 60 patients were included: 20 in the UNHBD group and 40 in the control group. The incidence of ischemic cholangiopathy was 5% (n = 1) for the UNHBD group and 0% for the BDD group (P = 0.15). The rate of primary nonfunction was 10% (n = 2) in UNHBD recipients and 2.5% (n = 1) in BDD recipients (P = 0.21), with graft loss in all of them. Three patients were retransplanted in the UNHBD group (15%), 2 of them because of primary nonfunction and 1 because of ischemic cholangiopathy; no patient was retransplanted in the control group (P = 0.012). After a mean follow-up of 330.4 +/- 224.9 days, 1-year cumulative patient survival was 85.5% for the UNHBD group and 87.5% for the BDD group (P = 0.768). One-year cumulative graft survival was 80% in the UNHBD group and 87.5% in the BDD group (P = 0.774). In conclusion, UNHBDs under NECMO are a potential source of organs for OLT with encouraging outcomes potentially comparable to those obtained with BDDs.
PIV Study of Nanoparticle Fluidization (2006)

Degussa Aerosil R974 powder, with a primary particle size of 12 nm, was fluidized using nitrogen in a glass vessel of 46 mm square cross-section. The settling velocities of the nanoparticle aggregates were obtained through PIV (particle image velocimetry) analysis of images of nanoparticle aggregates recorded with a high-resolution digital CCD camera. The results enable improved understanding of fluidization characteristics of nano-sized particles.

It is possible to prepare, evaluate, and ship DMEK grafts loaded inside a glass carrier and viewing chamber. The ability to evaluate tissues after processing allows for adherence to the Eye Bank Association of America Medical Standards, and for surgeons to receive the most accurate tissue information.
Organ Procurement and Transplantation Network/United Network for Organ Sharing Histocompatibility Committee Collaborative Study to Evaluate Prediction of Crossmatch Results in Highly Sensitized Patients (2009)

The above results showed that with the advent of solid phase immunoassays, HLA antibodies can now be accurately detected resulting in prediction of crossmatch outcome. This should facilitate organ allocation and prevents shipment of organs to distant incompatible recipients.
Low-power thermal isolation for environmentally resistant microinstrumfnts (2005)

This paper reports the design and analysis of a generic thermal isolation platform that can support a variety of MEMS devices and isolate them from the environment. The platform provides high thermal isolation from the environment by employing long meandering and hollow support metal beams. This isolation is needed for low power (<10mW) micro oven controlled constant temperature operation over a -50/spl sim/70 /spl deg/C temperature range. These beams also provide mechanical support. Optimal selection of the thermal and mechanical characteristics of these beams depends on many factors including beam materials, shape and structure, and the number of electrical signals. Metal only, meandering and hollow beams provide the highest thermal isolation and mechanical stiffness. The combination of the isolation platform batch fabrication process and wafer level instrument transfer/assembly onto the platform enables its broad and cost effective application.
High-grade clear cell renal cell carcinoma has a higher angiogenic activity than low-grade renal cell carcinoma based on histomorphological quantification and qRT–PCR mRNA expression profile (2007)

Clear cell renal cell carcinoma (CC-RCC) is a highly vascularised tumour and is therefore an attractive disease to study angiogenesis and to test novel angiogenesis inhibitors in early clinical development. Endothelial cell proliferation plays a pivotal role in the process of angiogenesis. The aim of this study was to compare angiogenesis parameters in low nuclear grade (n=87) vs high nuclear grade CC-RCC (n=63). A panel of antibodies was used for immunohistochemistry: CD34/Ki-67, carbonic anhydrase IX, hypoxia-inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF). Vessel density (MVD - microvessel density), endothelial cell proliferation fraction (ECP%) and tumour cell proliferation fraction (TCP%) were assessed. mRNA expression levels of angiogenesis stimulators and inhibitors were determined by quantitative RT-PCR. High-grade CC-RCC showed a higher ECP% (P=0.049), a higher TCP% (P=0.009), a higher VEGF protein expression (P<0.001), a lower MVD (P< 0.001) and a lower HIF-1alpha protein expression (P=0.002) than low-grade CC-RCC. Growth factor mRNA expression analyses revealed a higher expression of angiopoietin 2 in low-grade CC-RCC. Microvessel density and ECP% were inversely correlated (Rho=-0.26, P=0.001). Because of the imperfect association of nuclear grade and ECP% or MVD, CC-RCC was also grouped based on low/high MVD and ECP%. This analysis revealed a higher expression of vessel maturation and stabilisation factors (placental growth factor, PDGFB1, angiopoietin 1) in CC-RCC with high MVD, a group of CC-RCC highly enriched in low nuclear grade CC-RCC, with low ECP%. Our results suggest heterogeneity in angiogenic activity and vessel maturation of CC-RCC, to a large extent linked to nuclear grade, and, with probable therapeutic implications.
Levodopa‐induced dyskinesia in Parkinson disease: Current and evolving concepts (2018)

Levodopa-induced dyskinesia is a common complication in Parkinson disease. Pathogenic mechanisms include phasic stimulation of dopamine receptors, nonphysiological levodopa-to-dopamine conversion in serotonergic neurons, hyperactivity of corticostriatal glutamatergic transmission, and overstimulation of nicotinic acetylcholine receptors on dopamine-releasing axons. Delay in initiating levodopa is no longer recommended, as dyskinesia development is a function of disease duration rather than cumulative levodopa exposure. We review current and in-development treatments for peak-dose dyskinesia but suggest that improvements in levodopa delivery alone may reduce its future prevalence. Ann Neurol 2018;84:797-811.
Polyphenolics profile and antioxidant properties of<i>Raphanus sativus</i>L. (2011)

Raphanus sativus, a common cruciferous vegetable has been attributed to possess a number of pharmacological properties. Antioxidant and radical scavenging activity of R. sativus root extracted with solvents of varying polarity were evaluated using different model systems. Polyphenolic content was estimated to be in the range 13.18-63.54 mg g⁻¹ dry weight, with a considerable amount being obtained with polar solvents. High-performance liquid chromatography analysis indicated the presence of an array of polyphenolics. Catechin was found to be the most abundant phenolic compound in water extract and sinapic acid, the predominant phenolic compound in methanolic, ethyl acetate and hexane extracts. The methanolic extract showed significant ferric reducing ability, moderate metal chelating activity and strong radical scavenging activity. The methanolic extract could be successfully utilised as an ingredient in functional foods. However, water extract could be more pertinent to human nutrition as it contained a significant amount of catechin, which was comparable to traditional sources like green and black tea.
Stimulation of tumour growth by wound-derived growth factors (1999)

The goal of this work was to determine the molecular basis for the induction of tumour vascularization and progression by injury. Magnetic resonance imaging (MRI) studies demonstrated that administration of wound fluid derived from cutaneous injuries in pigs reduced the lag for vascularization and initiation of growth of C6 glioma spheroids, implanted in nude mice, and accelerated tumour doubling time. The former effect can be attributed to the angiogenic capacity of wound fluid as detected in vivo by MRI, and in vitro in promoting endothelial cell proliferation. The latter effect, namely the induced rate of tumour growth, is consistent with the angiogenic activity of wound fluid as well as with the finding that wound fluid was directly mitogenic to the tumour cells, and accelerated growth of C6 glioma in spheroid culture. Of the multiple growth factors present in wound fluid, two key factors, heparin-binding epidermal growth factor (EGF)-like growth factor (HB-EGF) and platelet-derived growth factor (PDGF), were identified as the dominant mitogens for C6 glioma, and inhibition of their activity using specific neutralizing antibodies suppressed the mitogenic effect of wound fluid on DNA synthesis in C6 glioma. This study suggests that the stimulatory effect of injury on tumour progression can possibly be attenuated by therapeutic targeting directed against a limited number of specific growth factors.
PTEN Regulates RANKL- and Osteopontin-stimulated Signal Transduction during Osteoclast Differentiation and Cell Motility (2003)

PTEN (also known as MMAC-1 or TEP-1) is a frequently mutated tumor suppressor gene in human cancer. PTEN functions have been identified in the regulation of cell survival, growth, adhesion, migration, and invasiveness. Here, we characterize the diverse signaling networks modulated by PTEN in osteoclast precursors stimulated by RANKL and osteopontin (OPN). RANKL dose-dependently stimulated transient activation of Akt before activation of PTEN, consistent with a role for PTEN in decreasing Akt activity. PTEN overexpression blocked RANKL-activated Akt stimulated survival and osteopontin-stimulated cell migration while a dominant-negative PTEN increased the actions of RANKL and OPN. PTEN overexpression suppressed RANKL-mediated osteoclast differentiation and OPN-stimulated cell migration. The PTEN dominant-negative constitutively induced osteoclast differentiation and cell migration. Our data demonstrate multiple roles for PTEN in RANKL-induced osteoclast differentiation and OPN-stimulated cell migration in RAW 264.7 osteoclast precursors.
