Uterine artery waveform as a predictor of pregnancy outcome in women with underlying renal disease. (1994)

To investigate the use of uterine artery flow velocity waveforms in predicting gestational hypertension (GH), preeclampsia (PE) and intrauterine growth retardation (IUGR), Colour Doppler ultrasound of the uterine arteries was performed at 19-24 weeks gestation in 51 women with known renal disease. On four consecutive waveforms, peak systolic (A), end-diastolic (B) and early diastolic (C) velocities were measured. Resistance index (RI) was calculated as (A-B)/A, and the severity of the waveform notch expressed as the AC ratio (A/C). Gestational hypertension was defined as a blood pressure (BP) > or = 140/90 mmHg with an increase of at least 15 mmHg in diastolic BP. PE included women with gestational hypertension and proteinuria > 300 mg/24 h or a doubling of early gestation protein excretion. IUGR was defined as a birthweight less than the 10th percentile for gestation. RI and/or AC ratio in 14 women (27%) exceeded the 90th percentile for gestational age of our low risk control population. Of the women with an abnormal test, 11 (79%) developed complications, 8 (57%) developed GH or PE, 3 (21%) IUGR alone, 2 (14%) GH and IUGR, and in one women intrauterine fetal death of an IUGR infant occurred, and 3 (21%) had an uncomplicated pregnancy. Of the women with a normal test, 34 (92%) had an uncomplicated pregnancy, and only 3 (8%) developed GH or IUGR. In summary, uterine artery waveform indices at 19-24 weeks gestation may be useful for the prediction of pregnancy complications in woman with underlying renal disease.
Collusion-Resistant digital video watermarking for copyright protection application (2016)

In this paper, a frame-by-frame blind video watermarking technique, which is resistant against collusion attack, is proposed. Collusion attack is the main problem in video watermarking for copyright protection. Whereby in this attack, colluders try to estimate and remove the watermark by comparing with as many as watermarked materials. To address the collusion attack in this work, each frame is assigned a different watermark. Since each frame has a unique watermark, it is impossible for the attack to estimate it. To achieve the required robustness as well as maintaining the quality, a combination of Block Truncation Coding (BTC), Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) techniques is used. The results show that the proposed method is robust against all types of collusion attack, and at the same time, the quality of the video is maintained at a satisfactory level.
Low-power object counting with hierarchical neural networks (2020)

Deep Neural Networks (DNNs) achieve state-of-the-art accuracy in many computer vision tasks, such as object counting. Object counting takes two inputs: an image and an object query and reports the number of occurrences of the queried object. To achieve high accuracy, DNNs require billions of operations, making them difficult to deploy on resource-constrained, low-power devices. Prior work shows that a significant number of DNN operations are redundant and can be eliminated without affecting the accuracy. To reduce these redundancies, we propose a hierarchical DNN architecture for object counting. This architecture uses a Region Proposal Network (RPN) to propose regions-of-interest (RoIs) that may contain the queried objects. A hierarchical classifier then efficiently finds the RoIs that actually contain the queried objects. The hierarchy contains groups of visually similar object categories. Small DNNs at each node of the hierarchy classify between these groups. The RoIs are incrementally processed by the hierarchical classifier. If the object in an RoI is in the same group as the queried object, then the next DNN in the hierarchy processes the RoI further; otherwise, the RoI is discarded. By using a few small DNNs to process each image, this method reduces the memory requirement, inference time, energy consumption, and number of operations with negligible accuracy loss when compared with the existing techniques.
Protein-tyrosine Phosphatase 1B Antagonized Signaling by Insulin-like Growth Factor-1 Receptor and Kinase BRK/PTK6 in Ovarian Cancer Cells* (2013)

Ovarian cancer, which is the leading cause of death from gynecological malignancies, is a heterogeneous disease known to be associated with disruption of multiple signaling pathways. Nevertheless, little is known regarding the role of protein phosphatases in the signaling events that underlie the disease; such knowledge will be essential to gain a complete understanding of the etiology of the disease and how to treat it. We have demonstrated that protein-tyrosine phosphatase 1B (PTP1B) was underexpressed in a panel of ovarian carcinoma-derived cell lines, compared with immortalized human ovarian surface epithelial cell lines. Stable restoration of PTP1B in those cancer cell lines substantially decreased cell migration and invasion, as well as proliferation and anchorage-independent survival. Mechanistically, the pro-survival IGF-1R signaling pathway was attenuated upon ectopic expression of PTP1B. This was due to dephosphorylation by PTP1B of IGF-1R β-subunit and BRK/PTK6, an SRC-like protein-tyrosine kinase that physically and functionally interacts with the IGF-1R β-subunit. Restoration of PTP1B expression led to enhanced activation of BAD, one of the major pro-death members of the BCL-2 family, which triggered cell death through apoptosis. Conversely, inhibition of PTP1B with a small molecular inhibitor, MSI-1436, increased proliferation and migration of immortalized HOSE cell lines. These data reveal an important role for PTP1B as a negative regulator of BRK and IGF-1Rβ signaling in ovarian cancer cells.
3D-tracking of head and hands for pointing gesture recognition in a human-robot interaction scenario (2004)

We present our approach for visual tracking of head, hands and head orientation. Given the images provided by a calibrated stereo-camera, color and disparity information are integrated into a multi-hypotheses tracking framework in order to find the 3D-positions of the respective body parts. Based on the hands' motion, an HMM-based approach is applied to recognize pointing gestures. We show experimentally, that the gesture recognition performance can be improved significantly by using visually gained information about head orientation as an additional feature. Our system aims at applications in the field of human-robot interaction, where it is important to do run-on recognition in real-time, to allow for robot's egomotion and not to rely on manual initialization.
3D face reconstruction in a binocular passive stereoscopic system using face properties (2012)

In this paper, we introduce a novel approach for face stereo reconstruction in passive stereo vision system. Our approach is based on the generation of a facial disparity map, requiring neither expensive devices nor generic face models. It consists of incorporating face properties in the disparity estimation to enhance the 3D face reconstruction. An algorithm based on the Active Shape Model (ASM) is proposed to acquire 3D sparse estimation of the face with a high confidence. Using sparse estimation as guidance and considering the face symmetry and smoothness, the dense disparity is completed. Experimental results are presented to demonstrate the reconstruction accuracy of the proposed method.
An active learning design project for a junior-level kinematics and dynamics class (2003)

This paper describes a design and modeling experience that was added to a junior-level, mechanical engineering class (Kinematics and Dynamics). Students were tasked to design, build, model and demonstrate an apparatus that met the following criteria: (1) demonstrated one or more concepts developed in class; (2) had one or more attributes that could be varied; (3) took into account all parameters (intended and unintended) affecting the apparatus output, and (4) would be interesting to students 14 years of age and older. The last requirement ensured that the projects could be demonstrated meaningfully to high school groups visiting our campus. Students completed individual, post-project questionnaires, and reported that their understanding of concepts such as friction, impact, momentum, and projectile motion was enhanced as they constructed and tested their devices. Furthermore, most now understand that "real-world" problems often cannot be solved through the simple application of the analytical approaches presented in their textbooks.
Second Language Vocabulary Acquisition: An Experimental Study with Turkish EFL Learners (2008)

This study investigates the two types of second language vocabulary learning in an experimental design. 21 Turkish EFL learners were divided into two treatment groups. The definition group learned vocabulary through definitions of the words whereas a context group learned through a reading text. The vocabulary learning levels were checked through both recognition and recall tasks with post-tests given just after the treatment and retention-tests given two weeks after the treatment. The results of the 2X2 Mixed design AOVA showed that the context group outperformed the definition group in both recognition and recall tasks for both post-test and retention test.
Agent-based decentralized traffic signal timing (2017)

In this paper we discuss a multi-agent cooperative approach for decentralized, coordinated traffic systems. Intersection controllers are equipped with agents, i.e., autonomous software systems which are capable of communicating and cooperating with one another to achieve an individual or global goal. Our approach is based on real-world traffic parameters and constraints, and is meant to be implemented in existing traffic systems with minimal changes. Experimental results show that the agent-based approach outperforms the traditional pre-timed and actuated modes when traffic is heavy.

New Avenue of Research: Antiepileptic Drug and Estradiol Neuroprotection in Epilepsy (2008)

Current epilepsy therapy is symptomatic using antiepileptic drugs. This therapy suppresses seizures but does not prevent or cure epilepsy. Treatment strategies that could interfere with the process leading to epilepsy (epileptogenesis) would have significant benefits over the current approach. Neuronal damage contributing to restructuralization of the neuronal networks (especially in the hippocampus during temporal lobe epilepsy) is one of the significant components of ongoing epileptogenesis. Thus, treatment strategies alleviating seizure induced neuronal damage may become significant players against the deteriorating process of epileptogenesis. Current antiepileptic drugs, especially valproic acid, have some neuroprotective potential. However, frequently this potential is either insufficient or the side effects of long-term therapy cancel out the benefits. The attention is therefore aimed at different classes of drugs with already established neuroprotective potential. Steroid hormones are under investigation, especially two groups of these compounds: beta-estradiol and the selective estrogen receptor modulators--SERM. In low doses, beta-estradiol has neuroprotective potency in neurodegenerative diseases. However, its use in seizure-induced neuroprotection is confounded by the common perception of proconvulsant features of estrogens. Here, we review that both proconvulsant and neuroprotective features apply only under specific conditions and may be separated by therapy taking into account the dosage paradigm, timing, sex of the subjects and their gonadal hormone status. Several studies have demonstrated that beta-estradiol has indeed potency to protect neurons from seizure-induced damage. Additional studies are required to further elucidate the effects, exact conditions, and especially mechanisms of action of beta-estradiol in seizure-induced neuroprotection since new specific SERM may help to avoid some undesirable effects.
Leveraging Large Corpora Using Internet Search for Question Answering (2016)

In this experiment, we measure the potential contribution of internet search to question answering. The task is to correctly answer Jeopardy! questions, and for doing so we use our existing question answering system, "Watsonsim", the architecture of which follows the original IBM Watson. We compare the answering precision and recall with and without internet search data from Microsoft's Bing. To accommodate the new sources we included several additional procedures, in particular merging candidate answers with similar meaning, and removing any candidate answers which are forbidden. The experiments show the potential of the internet search to improve question answering in terms of both the accuracy and recall: the top rank accuracy increased by around 14%, reaching 20% precision, compared to only 6% precision when using local search, and the recall improved by 20%, reaching 52%, up from 32% using only local search engines. Tweaks to better handle web results later raised top-rank accuracy an additional 21%, reaching 41% precision, and raised recall by another 19%, to reach 71% recall. The overall conclusion of our experiments was to show that in question answering, a network enabled system can compensate for a smaller corpus and provide reasonably good answers.
Magnetocaloric and magnetoresistance properties in Co-based (Co<sub>0.402</sub>Fe<sub>0.201</sub>Ni<sub>0.067</sub>B<sub>0.227</sub>Si<sub>0.053</sub>Nb<sub>0.05</sub>)<sub>100−x</sub>Cu<sub>x</sub> (x=0–1) glassy alloys (2016)

The magnetocaloric and magnetoresistance properties of amorphous Co-based (Co0.402Fe0.201Ni0.067B0.227Si0.053Nb0.05)100−xCux (x = 0, 0.5, 0.75 and 1) ribbons were investigated. Cu additions changed the crystallisation temperature (Tx) and the Curie temperature (TC). The saturation magnetisation (Ms) and coercivity (Hc) for alloys were in the range of 65.51–38.49 emu/g and 1.99–6.84 A/m, respectively. Under an applied magnetic field change of 2.2 T, the (−ΔSM)max for (Co0.402Fe0.201Ni0.067B0.227Si0.053Nb0.05)100−xCux with x = 0, 0.5, 0.75 and 1 are 0.77, 0.71, 0.89 and 0.67 Jkg−1 K−1, respectively. The values of refrigeration capacity (RC) for the as-spun glassy alloys are comparable with those of previously studied Fe-based metallic glasses such as Fe80B10Zr9Cu1, (Fe0.76B0.24)96Nb4 and Fe82Ni2Zr6B10. In addition, the maximum magnetoresistance (MR) values for (Co0.402Fe0.201Ni0.067B0.227Si0.053Nb0.05)100−xCux with x = 0, 0.5, 0.75 and 1 are found to be 110, 38, 23 and 1% around the Curie temperatures under an applied magnetic field change of 1 T, respectively. With good RC, negligible hysteresis due to very low coercivity values and large magnetoresistance, these Co-based amorphous alloys can be used as the high temperature magnetic refrigerants and multifunctional applications working in the temperature range of 450–600 K.
Scalable <i>in situ</i> single-cell profiling by electrophoretic capture of mRNA (2022)

Methods to spatially profile the transcriptome are dominated by a trade-off between resolution and throughput. Here, we developed a method named EEL FISH that can rapidly process large tissue samples without compromising spatial resolution. By electrophoretically transferring RNA from a tissue section onto a capture surface, EEL speeds up data acquisition by reducing the amount of imaging needed, while ensuring that RNA molecules move straight down towards the surface, preserving single-cell resolution. We applied EEL on eight entire sagittal sections of the mouse brain and measured the expression patterns of up to 440 genes to reveal complex tissue organisation. Moreover, EEL enabled the study of challenging human samples by removing autofluorescent lipofuscin, so that we could study the spatial transcriptome of the human visual cortex. We provide full hardware specification, all protocols and complete software for instrument control, image processing, data analysis and visualization.
Design of high-performance adaptive objective lens with large optical depth scanning range for ultrabroad near infrared microscopic imaging (2015)

We report on the theory and design of adaptive objective lens for ultra broadband near infrared light imaging with large dynamic optical depth scanning range by using an embedded tunable lens, which can find wide applications in deep tissue biomedical imaging systems, such as confocal microscope, optical coherence tomography (OCT), two-photon microscopy, etc., both in vivo and ex vivo. This design is based on, but not limited to, a home-made prototype of liquid-filled membrane lens with a clear aperture of 8mm and the thickness of 2.55mm ~3.18mm. It is beneficial to have an adaptive objective lens which allows an extended depth scanning range larger than the focal length zoom range, since this will keep the magnification of the whole system, numerical aperture (NA), field of view (FOV), and resolution more consistent. To achieve this goal, a systematic theory is presented, for the first time to our acknowledgment, by inserting the varifocal lens in between a front and a back solid lens group. The designed objective has a compact size (10mm-diameter and 15mm-length), ultrabroad working bandwidth (760nm - 920nm), a large depth scanning range (7.36mm in air) - 1.533 times of focal length zoom range (4.8mm in air), and a FOV around 1mm × 1mm. Diffraction-limited performance can be achieved within this ultrabroad bandwidth through all the scanning depth (the resolution is 2.22 μm - 2.81 μm, calculated at the wavelength of 800nm with the NA of 0.214 - 0.171). The chromatic focal shift value is within the depth of focus (field). The chromatic difference in distortion is nearly zero and the maximum distortion is less than 0.05%.

An open framework for foundational proof-carrying code (2007)

Today's software systems often use many different computation features and span different abstraction levels (e.g., user code and runtime-system code). To build foundational certified systems, it is hard to have a single verification system supporting all computation features. In this paper we present an open framework for foundational proof-carrying code (FPCC). It allows program modules to be specified and certified separately using different type systems or program logics. Certified modules (i.e., code and proof) can be linked together to build fully certified systems. The framework supports modular verification and proof reuse. It is also expressive enough so that invariants established in specific verification systems are preserved even when they are embedded into our framework. Our work presents the first FPCC framework that systematically supports interoperation between different verification systems. It is fully mechanized in the Coq proof assistant with machine-checkable soundness proof.

Analysis of cost and accuracy of alternative strategies for Enterobacteriaceae identification (1976)

Analysis of the cost of time and material required for the diagnosis of Enterobacteriacea isolates indicated that a conventional 17-tube (20-test) setup costs $7.98 per isolated identified. Using the API 20E, a similar identification cost $3.02. A conventional 7-tube (10-test) setup cost $3.60, whereas the comparable cost by 30% while increasing the number of isolate identified correctly by 3%. Other strategres using the API 20E or a deoxyribounclease test were also evaluated for cost and accuracy.
Functional analysis of NTF-1, a developmentally regulated Drosophila transcription factor that binds neuronal cis elements. (1989)

In an effort to characterize sequence-specific transcription factors that regulate gene expression during Drosophila development, we identified and purified a novel DNA-binding activity (NTF-1). The purified protein consists of several polypeptides that bind selectively to a functionally important cis-control element of the Ultrabithorax (Ubx) promoter and to the neurogenic elements of both the dopa decarboxylase (Ddc) and fushi tarazu (ftz) promoter/enhancer regions. Purified NTF-1 activates transcription in vitro in a binding site-dependent manner through upstream sequences of the Ubx promoter. A cDNA clone encoding the open reading frame of NTF-1 was isolated, and the deduced primary amino acid sequence of NTF-1 includes a glutamine-rich region reminiscent of the transcriptional activation domains found in Sp1 but no recognizable DNA-binding domain. NTF-1 expression is temporally regulated during embryonic development. In addition, in situ hybridization experiments revealed that NTF-1 is transcribed in a spatially restricted pattern in the embryo, with the highest level of expression observed in the epidermis and a subset of cells in the CNS. Expression of the NTF-1 cDNA in mammalian cells yields a protein that displays DNA-binding and transcriptional activities indistinguishable from that of the collection of proteins isolated from Drosophila embryos. These findings suggest that NTF-1 is a member of a family of developmentally regulated transcription factors that may be involved in directing the expression of genes such as Ubx, Ddc, and ftz in neuronal cells.
