Predicting Nonlinear Distortion in Common-Emitter Stages for Amplifier Design Using Volterra Series (2002)

In this paper we present a method for predicting nonlinear distortion in electronic circuits using the Volterra series. Simple expressions for the distortion in a Common-Emitter stage are determined. Designers may use these expressions to get a quick insight in both qualitative and quantitative aspects of the distortion. Also predictors are given for the maximum distortion in different situations.
From map images to geographic names (2014)

Map labels provide valuable geographic information by annotating geographic phenomenona with text descriptions. However, many interesting and useful maps are only available as images and hence this information is not readily accessible in a Geographic Information System (GIS). Previous work on text recognition in maps considers maps as a special type of image to be processed using Optical Character Recognition (OCR) techniques and does not pay attention to the typical workflows in a GIS. As a result, to convert map labels into machine-readable text, a user has to switch between OCR and GIS software, transform the detected text locations from the image coordinates (in OCR) to the map coordinates (in GIS), and apply data import/export procedures. This tedious process limits the opportunity to access text information in maps. This paper presents ArcStrabo, an integration of our previous text recognition work and a GIS, which uses a GIS user interface, workflows, and data types to enable efficient training of text recognition algorithms for converting map labels to a table of geographic names. We show that ArcStrabo facilitates map digitization processes, eliminates the need for GIS users to learn additional OCR tools, and does not require manual data export/import procedures between GIS and OCR software.
One Thousand Liver Transplants The Lessons Learned (1994)

Despite unfavorable donor characteristics (obesity, cause of death, age, hypotension), most organs function well and should not be refused based on history alone. The older and high-risk patient (renal failure, ventilator dependence, portal vein pathology, and so on) is routinely transplanted with good success. Despite liberalization of both donor and recipient criteria, patient survival after liver transplant is improved, use of hospital resources is maximized, and cost reduction is achieved.

Target detection from MPEG video based on low-rank filtering in the compressed domain (2010)

There are advantages of using the motion vector obtained from the MPEG video coding to perform target of interest
identification in the field. In practice, however, environment noise, time-varying, and uncertainty factors affect their
performance reliably and accurately detecting targets of interest. In this paper, we proposed a novel low rank filtering
based on L 1 norm in order to straighten up single rogue or outliers that might show up fairly often. Finally, a simple
average smoothing filter was applied to reduce vector quantization noise. By using the low rank filtering based on L 1 
norm, the dominant motion vectors from the MPEG video coding can be extracted appropriately with respect to target
operational responses and can be used for robust identification of moving target. The performance of the proposed
approach was evaluated based on a set of experimental camera motion. The motions, including pan, tilt, and zoom, was
computed from the motion vectors, and the residual vectors which are not described by the camera motion are regarded
as generated by moving blobs. Events, as a result, can be detected from these moving blobs. It is demonstrated that the
approach yields very promising results where motion vectors obtained from the MPEG video coding can be used
efficiently to detect and identify moving target in the field.
Circuit Theory for Analysis and Design of Spintronic Integrated Circuits (2011)

We present a theoretical and a numerical formalism for analysis and design of spintronic integrated circuits (SPINICs). The formalism encompasses a generalized circuit theory for spintronic integrated circuits based on nanomagnetic dynamics and spin transport. We propose an extension to the Modified Nodal Analysis technique for the analysis of spin circuits based on the recently developed spin conduction matrices. We demonstrate the applicability of the framework using an example spin logic circuit described using spin Netlists.
Endothelium-derived semaphorin 3G attenuates ischemic retinopathy by coordinating β-catenin–dependent vascular remodeling (2021)

Abnormal angiogenesis and regression of the diseased retinal vasculature are key processes associated with ischemic retinopathies, but the underlying mechanisms that regulate vascular remodeling remain poorly understood. Here, we confirmed the specific expression of semaphorin 3G (Sema3G) in retinal endothelial cells (ECs), which was required for vascular remodeling and the amelioration of ischemic retinopathy. We found that Sema3G was elevated in the vitreous fluid of patients with proliferative diabetic retinopathy (PDR) and in the neovascularization regression phase of oxygen-induced retinopathy (OIR). Endothelial-specific Sema3G knockout mice exhibited decreased vessel density and excessive matrix deposition in the retinal vasculature. Moreover, loss of Sema3G aggravated pathological angiogenesis in mice with OIR. Mechanistically, we demonstrated that HIF-2α directly regulated Sema3G transcription in ECs under hypoxia. Sema3G coordinated the functional interaction between β-catenin and VE-cadherin by increasing β-catenin stability in the endothelium through the neuropilin-2 (Nrp2)/PlexinD1 receptor. Furthermore, Sema3G supplementation enhanced healthy vascular network formation and promoted diseased vasculature regression during blood vessel remodeling. Overall, we deciphered the endothelium-derived Sema3G-dependent events involved in modulating physiological vascular remodeling and regression of pathological blood vessels for reparative vascular regeneration. Our findings shed light on the protective effect of Sema3G in ischemic retinopathies.

Effects of Gamma Radiation on Bone-Marrow Stromal Cells (2010)

The effects of in vitro irradiation on proliferation and hematopoietic supportive functions of stromal cells were studied. To assess the effects of radiation on stromal cells proliferation, marrow cells were exposed to a single dose of gamma radiation. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed that stromal cell proliferation was significantly suppressed after radiation in a dose-dependent manner. Stromal layers obtained from irradiated marrow cells failed to establish adherent layers after 6, 8, or 10 Gy of radiation. To assess the functions of stromal cells that survived radiation, stromal layers derived from irradiated marrow cells were cocultured with freshly isolated autologous hematopoietic cells and assayed for their capacity to support prolonged granulocyte–macrophage progenitors (CFU-GM) production. Stromal layers derived from 2-Gy-irradiated marrow cells resulted in similar CFU-GM production as control cells, while stromal layers derived from 4- to 10-Gy-irradiated marrow cells significantly decreased CFU-GM production. To study the influence of radiation on hematopoietic supportive capacity in established stromal layers, stromal layers generated from non-irradiated marrow cells were irradiated and cocultured with freshly isolated autologous hematopoietic cells. Established stromal layers irradiated up to 10 Gy sustained prolonged CFU-GM production, suggesting that hematopoietic stromal supportive functions remained intact at this dose of radiation. In conclusion, our results indicated that proliferation of stromal cells and bone-marrow stromal layer formation from stromal cells are sensitive to radiation in vitro, while established bone-marrow stromal layer originating from stromal cells is relatively resistant to radiation. Data generated may have implications in future bone-marrow transplantation research.
Health Talk: Understanding Practices of Popular Professional YouTubers (2022)

Practices related to health are circulated widely on YouTube. With a health psychology perspective, we present a study to understand health and wellbeing-related practices of a group of popular, professional YouTubers from the audio-visual content they produce. We first identify, via polytextual thematic analysis, six thematic health-related categories, and use them to label a set of 2500 YouTube videos. Agreement among three independent annotators was acceptable for these health-related categories. We then present an analysis of speech transcriptions and visual content, demonstrating that distinctive patterns exist for these health-related categories. These include linguistic markers and specific scene types and objects. Finally, with an interpretability focus, we study the feasibility of classifying health-related video categories in a binary setting, and compare performance across features, finding best accuracy for linguistic features (74-87%), and various patterns of linguistic and visual relevance used for the classification of health categories. The results shows promise to support mixed-methods research in health psychology, combining manual analysis and data-driven methods. More generally, our work contributes to the understanding of current health practices shared and promoted on social video.

Video Surveillance of Medication Intake (2006)

In the context of the growing proportion of seniors in the western world population and the efforts provided in home care services, we have developed a computer vision system for monitoring medication intake. The system detects automatically medication intake using a single low-cost webcam. Person detection and tracking over the video sequence is done using color-based techniques while the recognition of the medication intake activity is performed using our main contribution, a three-level scenario model. Experimental results in controlled conditions are shown and we discuss improvements to our system.
Single-mode vertical-cavity surface-emitting lasers grown under accurate real-time optical control (2002)

Summary form only given. We applied an optical real-time growth control technique: TDOR (tunable dynamic optical reflectometry) to grow GaAs/AlGaAs-based VCSELs. TDOR control consists of exploiting reflectivity interferences measured on the growing multilayer with a tunable optical source. Prior to the growth, a set of optimal wavelengths corresponding to the successive layers to be controlled, is calculated within the tunable laser emission range. For each optimal wavelength, a reflectivity extremum is observed when the aimed corresponding layer thickness is attained, thus allowing a direct use of the reflectometry signal for effusion cells shutters synchronisation. For VCSELs, the influence of both the QWs in the cavity and the numerous graded composition layers inserted at each DBR interface have been taken into account in TDOR modelling, as well as the different substrate temperatures applied during growth. After growth, the structures have been processed using RIE to define mesas, BCB for planarization and finally selective lateral oxidation of an AlAs layer near the cavity in order to form a buried oxide aperture.
Genomic Sequence and Transcriptional Analysis of a 23-Kilobase Mycobacterial Linear Plasmid: Evidence for Horizontal Transfer and Identification of Plasmid Maintenance Systems (2001)

Linear plasmids were unknown in mycobacteria until recently. Here, we report the complete nucleotide sequence of 23-kb linear plasmid pCLP from Mycobacterium celatum, an opportunistic pathogen. The sequence of pCLP revealed at least 19 putative open reading frames (ORFs). Expression of pCLP genes in exponential-phase cultures was determined by reverse transcriptase PCR (RT-PCR). Twelve ORFs were expressed, whereas no transcription of the 7 other ORFs of pCLP was detected. Five of the 12 transcribed ORFs detected by RT-PCR are of unknown function. Sequence analysis revealed similar loci in both M. celatum pCLP and the Mycobacterium tuberculosis chromosome, including transposase-related sequences. This result suggests horizontal transfer between these two organisms. pCLP also contains ORFs that are similar to genes of bacterial circular plasmids involved in partition (par operon) and postsegregational (pem operon) mechanisms. Functional analysis of these ORFs suggests that they probably carry out similar maintenance roles in pCLP.

Electrical and Thermal Properties of Spinels (2005)

The properties of spinel oxides were studied in an effort to identify a potential solid oxide fuel cell (SOFC) interconnect coating which can hinder chromium oxide growth and evaporation as well provide acceptable electrical conductivity. Transition metal spinels based on aluminum, chromium, manganese and iron were examined. The electrical conductivities were measured in air from 500 to 800°C by the standard four-probe DC method. Additionally, the thermal expansion coefficients of some samples were measured in air from room temperature to 1000°C. The stoichiometric aluminates, chromites and manganites have thermal expansion coefficients that lie consistently in the 7–9 ppm/K range. Thermal expansion coefficients of the ferrites are in the 11–13 ppm/K range, and their conductivities are generally 0.1–10 S/cm. Conductivities of the aluminates are all less than 10−2 S/cm. Among the potential candidates for SOFC interconnect coatings, Co2MnO4 has a conductivity of 55 S/cm at 800°C and a thermal expansion coefficient of 9.7 ppm/K and CuFe2O4 has a conductivity of 9.1 S/cm at 800°C and a thermal expansion coefficient of 11.2 ppm/K. The ternary spinel oxides of CuMn2−xCrxO4 (x = 0.2, 0.6, 0.8 and 1.0) and Co2Mn0.5Cr0.5O4 are also acceptable in terms of their electrical conductivities and thermal expansion coefficients.
SOLIDS CIRCULATION IN SPOUTED AND SPOUT-FLUID BEDS WITH DRAFT-TUBES (1990)

Abstract A 20 cm semi-cylindrical spout-fluid bed with a draft-tube has been used to investigate the effect of various physical parameters on the solids circulation rate, A new method has been developed by which these data can be easily and accurately collected. Equations are presented which can be used to predict the maximum attainable solids circulation rate and the spouting velocity required to achieve this maximum for the unit operating in spouting mode. The circulation trends are shown to be a direct result of the phenomena of entrainment and jetting occurring in the entrainment zone investigated visually with a video camera. Preliminary gas bypassing experiments were also performed which show the ability to almost eliminate spout gas bypassing to the annulus with appropriate auxiliary gas addition.

Penicillium expansum versus antagonist yeasts and patulin degradation in vitro (2007)

Taking into account the preliminary antagonistic/biodegradation property showed by Pichia membranifaciens and Sporobolomyces roseus, which decreased the initial patulin concentration of 588.4 to 290.0 µg/mL, ability of P. ohmeri 158 in biocontrol against Penicillium expansum and patulin decrease in vitro was performed. The culture supernatant of P. ohmeri 158 was effective against 66.17% micelial growth, indicating antibiosis related with the killer phenomenon. The initial patulin concentration of 223 µg in the presence of P. ohmeri 158 cells was decreased over 83% of the original concentration, when incubated at 25ºC/2 days and &gt; 99% after 5 days incubation time, with undetectable patulin level after 15 days. The initial pH 4.0 decreased to pH 3.3 along 15 days experiment, suggesting that patulin decrease was an active process and a consequence of yeast metabolism. The results suggested that P. ohmeri 158 could be a promising alternative for the inhibition of P. expansum growth and patulin degradation.

Fast and accurate scan registration through minimization of the distance between compact 3D NDT representations (2012)

Registration of range sensor measurements is an important task in mobile robotics and has received a lot of attention. Several iterative optimization schemes have been proposed in order to align three-dimensional (3D) point scans. With the more widespread use of high-frame-rate 3D sensors and increasingly more challenging application scenarios for mobile robots, there is a need for fast and accurate registration methods that current state-of-the-art algorithms cannot always meet. This work proposes a novel algorithm that achieves accurate point cloud registration an order of a magnitude faster than the current state of the art. The speedup is achieved through the use of a compact spatial representation: the Three-Dimensional Normal Distributions Transform (3D-NDT). In addition, a fast, global-descriptor based on the 3D-NDT is defined and used to achieve reliable initial poses for the iterative algorithm. Finally, a closed-form expression for the covariance of the proposed method is also derived. The proposed algorithms are evaluated on two standard point cloud data sets, resulting in stable performance on a par with or better than the state of the art. The implementation is available as an open-source package for the Robot Operating System (ROS).
Compact robotics perception system based on a laser range finder coupled with silicon micromirrors (2003)

A compact perception system—originally developed for real-time acquisition of 3-D images for robotics applications—is presented. For distances up to 12 m, the resolution is about 2 cm at a rate of 5 images/s, with a field of view better than m20 deg. The setup is based on a specifically designed phase-shift laser range finder coupled with two micromachined silicon mirrors with a size of 4×4 mm. A sensor gives the Cartesian position of the laser spot. Data obtained from scanning are stored in numerical form in a 4096 10-bit words RAM. This design intends to provide a device with as many silicon components as possible, in view of achieving a very large integration in the near future. We describe the current device and analyze experimental results.
Fatty acids of canola Brassica campestris var candle seed and oils at various stages of refining (1981)

Abstract Fatty acids of oil of a current variety of canola Brassica campestris var Candle, at 3 stages of commercial production and refining, were compared with authentic seed oils, and with the oil of B. napus var Tower. The proportion of cis‐ 9, cis‐ 12, trans‐ 15 and trans‐ 9 , cis‐12, cis‐lS‐octadecatrienoates relative to the all‐cis isomer was lower than that previously observed in processed oils. The minor C 14 , C 15 , C 17 fatty acids previously documented for Tower were also found in the same proportions in the Candle oil. The proportion of 22:1ω7 isomer (1.1% of a total 1.2% 22:1) was intermediate to that of a high erucic variety (0.9% out of 23% 22:1) and the very low 22:1 Tower (2.3% out of 0.1% 22:1). Thus the proportion of ω7 isomers is governed by total 22:1 present.
Study on Detection Technique for Jetting Failure of Piezo-Driven Inkjet Heads (2008)

In recent years inkjet technology has a wide range of application including Flat Panel Display and Semiconductors. As compared with consumer appliances, industrial inkjet requires higher specifications in terms of dot placement accuracy and droplet volume uniformity. The stability of inkjet is a major requirement and then an in-situ monitoring system for inkjet condition is strongly required to prevent inferior products. In piezo-driven inkjet heads, the piezo actuators can be used as sensors to detect jetting failures caused by air bubbles. This might be the key technology to improve the reliability of the inkjet process. In this paper, we propose the model of jetting failure detection system and point out how the modification of the inkjet driving circuit for better jetting performance influences on the detection results. The prototype of the jetting failure detection system is developed and used to validate the detection algorithm both in time and frequency domain. This prototype and detection algorithm can realize the in-situ monitoring for all jetting due to high-speed system configuration.
