Parallel Detection for Efficient Video Analytics at the Edge (2021)

Deep Neural Network (DNN) trained object detectors are widely deployed in many mission-critical systems for real time video analytics at the edge, such as autonomous driving and video surveillance. A common performance requirement in these mission-critical edge services is the near real-time latency of online object detection on edge devices. However, even with well-trained DNN object detectors, the online detection quality at edge may deteriorate for a number of reasons, such as limited capacity to run DNN object detection models on heterogeneous edge devices, and detection quality degradation due to random frame dropping when the detection processing rate is significantly slower than the incoming video frame rate. This paper addresses these problems by exploiting multi-model multi-device detection parallelism for fast object detection in edge systems with heterogeneous edge devices. First, we analyze the performance bottleneck of running a well-trained DNN model at edge for real time online object detection. We use the offline detection as a reference model, and examine the root cause by analyzing the mismatch among the incoming video streaming rate, video processing rate for object detection, and output rate for real time detection visualization of video streaming. Second, we study performance optimizations by exploiting multi-model detection parallelism. We show that the model-parallel detection approach can effectively speed up the FPS detection processing rate, minimizing the FPS disparity with the incoming video frame rate on heterogeneous edge devices. We evaluate the proposed approach using SSD300 and YOLOv3 on benchmark videos of different video stream rates. The results show that exploiting multi-model detection parallelism can speed up the online object detection processing rate and deliver near real-time object detection performance for efficient video analytics at edge.
A Dual-Axis Liquid Micro Rate Gyroscope Using an Electro-Conjugate Fluid (2011)

We propose a novel dual-axis liquid micro rate gyroscope using an electro-conjugate fluid (ECF). The ECF is a dielectric fluid which works here as a smart fluid generating a powerful jet flow (ECF jet) under a strong DC electric field. The driving principle of this gyroscope using an ECF is based on that of a conventional gas rate sensor. In our previous study, a single-axis liquid micro rate gyroscope using an ECF was proposed and the performance of this gyroscope was investigated by experiments. The proposed gyroscope becomes much thinner than a dual-axis gyroscope composed of two single-axis liquid micro rate gyros. This paper describes the design of the proposed gyroscope and the investigation for the improvement of its performance. As a result of experiments, we obtained the optimized main dimension and lower driving voltage (decline by 49%). Additionally, we confirmed that there was not cross talk in the proposed gyroscope.
Nitro-oxidized carboxylated cellulose nanofiber based nanopapers and their PEM fuel cell performance (2022)

Sustainable and highly proton conductive nanopapers were prepared from carboxycellulose nanofibers and applied in PEM fuel cells.
Septal deviation in neonates. (1989)

Deviated nasal septum (DNS) is believed to occur in neonates following the trauma of birth processes. The present prospective study was undertaken to evaluate the relationship of intrauterine and parturition processes with neonatal septal dislocations. The neonates were subjected to a series of tests to assess presence and extent of deviated septum within the first 48 hours. A statistically significant correlation was demonstrable between the incidences of septal deviations with intra uterine fetal positions and mode of delivery.

Modification of Physical Characteristics of Microcrystalline Cellulose by Codrying with β-Cyclodextrins (1998)

In an attempt to modify the physical properties of microcrystalline cellulose (MCC), the slurry form of this material was codried with beta-cyclodextrin (beta-CD). MCC slurry was blended with beta-CD at concentrations of 10%-50% w/w as a dried mass relative to MCC. The mixtures were then granulated with water and codried at 60 degrees C for 12 h or until a constant weight was reached. Codried granules were pulverized, and the fraction between 61 and 150 microns in size was reserved. The powder and tableting properties of the codried products were compared to those of various grades of MCC and the corresponding components and physical mixtures. The results showed that the products of MCC codried with beta-CD significantly improved the flowability of MCC powder. It is probable that the improved flowability was due to the more rounded shape of particles formed with this codried process, which was confirmed by SEM photographs. Moreover, the compactibility and disintegration properties of tablets produced from the codried products were even better than those using MCC alone, physical mixtures, or various grades of MCC. MCC in a slurry form was more efficient than the existing MCC products in achieving these results, which is postulated to be due to the greater amount of water required and the higher solubility of beta-CD in water promoting the interaction between beta-CD and MCC during granulation. In conclusion, MCC codried with beta-CD provides a useful excipient for direct compression.
Synthesis of artificial receptors as potential candidates for recognition and binding of pterin analogs (1995)

Abstract Open chain podands 2a‐c and macrocycles 2d‐e have been synthesized as potential candidates for 4‐aminopterin recognition and binding, featuring Hbonding characteristics and “stacking interaction” 2e. Preliminary binding studies between 6, 7 , and 8 (simpler analogs of the above 2a‐e ) as “bosts” and appropriate “guests”, showed that carbamates 2a and 2e are the most promising receptors for 4‐aminopterin binding.
p53 immunostaining in combined type small cell lung cancer (1995)

Abnormalities of the p53 oncogene in lung cancer have recently been reported to be more frequent in small cell lung cancer (SCLC) than in non-small cell lung cancer (non-SCLC), but their status in combined type SCLC is as yet unknown. In this study, immunohistochemical analysis using a polyclonal antibody against p53 protein was performed in 12 surgically resected specimens of combined type SCLC. Immunoreactivity of the p53 protein was found in 5 (42%) of the 12 cases, and the immunostaining pattern of the p53 protein in areas of the non-small cell carcinoma type was the same as in those of the small cell carcinoma type. Thus, it seems that the incidence of p53 abnormalities in combined type SCLC is slightly lower than in ordinary type SCLC. It is also suggested that abnormalities of the p53 oncogene in this histological type may not be a specific event related to the morphological difference between small cell carcinoma and non-small cell carcinoma.
MRI‐guided noninvasive ultrasound surgery (1993)

In this study, the feasibility of using magnetic resonance imaging (MRI) to detect tissue necrosis induced by focussed ultrasound beams was investigated. It was shown that lesions produced in dog's thigh muscle in vivo were clearly visible in T2-weighted images and that the lesion dimensions measured from the images correlated with the postmortem measurements of the visible tissue damage. It was also shown that the sonications can be done in the magnet and that the lesions are visible immediately after the sonications with increasing image contrast as a function of time. These results showed that MRI can be used to direct and monitor on-line noninvasive ultrasound surgery. This may have a major impact in future patient treatments.
Eye detection method robust to facial pose changes for eye input device (2011)

In this paper, we propose an eye detection method that is robust to facial poses changes using edge directional features and a particle filter. To estimate the boundary between the iris and sclera or eyelid, the gradient intensities are calculated by four directional Prewitt filters in four regions. The likelihood used in the particle filter is obtained by averaging the gradient intensities for the specific direction in the four regions and the upper eyelid area. Moreover, incorrect detection is avoided by using the eye distance and the roll angle of the face, derived from the positional information of both eyes. From experimental results, the average detection rates of both eyes for roll, yaw, and pitch angles of the face are more than 90% by using rejection function for incorrect eye detection. In addition, the rejection function provides the 2.8%, 4.3%, and 5.3% increment in average detection rates of both eyes for roll, yaw, and pitch facial angles, respectively. The proposed eye detection method is therefore robust to facial pose changes.
Entanglement Spectroscopy of non-Abelian Anyons (2018)

We study the entanglement spectrum of topological systems hosting non-Abelian anyons. Similar to energy levels of a Hamiltonian, the entanglement spectrum is organized into symmetry multiplets. We find that the ratio between different eigenvalues within one multiplet is universal and is determined by the anyonic quantum dimensions. This result is a consequence of the conservation of the total topological charge. For systems with non-Abelian topological order, this generalizes known degeneracies of the entanglement spectrum, which are hallmarks of topological states. Experimental detection of these entanglement spectrum signatures may become possible using multi-copy schemes allowing to measure quantum entanglement and its symmetry-resolution. We discuss such a protocol explicitly in the context of Majorana wires.
<title>Top-down guided eye movements: peripheral model</title> (2001)

Eye movements are an important aspect of human visual behavior. The temporal and space-variant nature of sampling a visual scenes requires frequent attentional gaze shifts, saccades, to fixate onto different parts of an image. Fixations are often directed towards the most informative regions in the visual scene. We introduce a model and its simulation that can select such regions based on prior knowledge of similar scenes. Having representations of scene categories as probabilistic combination of hypothetical objects, i.e., prototypical regions with certain properties, it is possible to assess the likely contribution of each image region to the successive recognition process. The regions are obtained by segmenting low-resolution images using the normalized cut algorithm. Based on low-level features, such as average color, size, position, regions are clustered into a small set of hypothetical objects. Using conditions probabilities for each object given the scene category, the model can then predict the informative value of the corresponding region and initiate a sequential spatial information-gathering algorithm analogous to an eye movement saccade to a new fixation. The article demonstrates how the initial hypothesis determines the next region of interest to visit and how these scene hypotheses are affected by sequentially visiting each new image region.
Additive manufacturing of complex objects using refractory matrix materials (2023)

A method for the manufacture of a three-dimensional object using a refractory matrix material is provided. The method includes the additive manufacture of a green body from a powder-based refractory matrix material followed by densification via chemical vapor infiltration (CVI). The refractory matrix material can be a refractory ceramic (e.g., silicon carbide, zirconium carbide, or graphite) or a refractory metal (e.g., molybdenum or tungsten). In one embodiment, the matrix material is deposited according to a binder-jet printing process to produce a green body having a complex geometry. The CVI process increases its density, provides a hermetic seal, and yields an object with mechanical integrity. The residual binder content dissociates and is removed from the green body prior to the start of the CVI process as temperatures increase in the CVI reactor. The CVI process selective deposits a fully dense coating on all internal and external surfaces of the finished object.

Self-Assembly of Dendrimers by Slippage (2002)

[reaction: see text] A dendrimer with rotaxane-like characteristics has been assembled under thermodynamic control from complementary wedge-shaped precursors by slippage in CH(2)Cl(2). The driving force for the self-assembly process is the molecular recognition that exists as a result of [N(+)-H.O] and [C-H.O] hydrogen bonds between an NH(2)(+) center in one Fréchet-type benzyl ether wedge and a dibenzo[24]crown-8 unit that links the other two such wedges.
Improving refractive index sensing by tailoring the lineshape and measuring the phase of plasmonic resonances (2012)

Plasmon resonances are known to exhibit a large sensitivity to the local refractive index. In order to establish an accurate measurement of the resonance wavelength position, it is beneficial if the resonance linewidth is narrow. We have been tailoring the lineshape of plasmonic resonances using symmetry breaking and the excitation of Fano resonances and by measuring the phase of the resonances. Substantial improvements are reported.
Clothing Recognition in the Wild using the Amazon Catalog (2019)

The emergence of online influencers, the explosion of video content, and the massive amount of movie collections have served as an advertising vehicle for the fashion industry. This trend has created the need for automated methods that recognize people's outfit in such image and video collections. However, existing computer vision solutions for fashion recognition require an enormous amount of labeled data for training, which is prohibitively expensive. In this work, we propose an approach to build clothing recognition models for real-world scenarios. Our approach exploits images from the Amazon Catalog as training data. By using the catalog data as an additional training source, we boost the recognition accuracy on the challenging real world images of the DeepFashion dataset achieving stateof-the-art performance. We introduce the first dataset for clothing recognition in movies. In this scenario, we find that the use of catalog data for training becomes even more crucial, as it provides an accuracy boost of 10%.
Improved Mechanical Properties of Chemically Amplified, Positive Tone, Polynorbornene Dielectric (2014)

The mechanical properties of an aqueous developed, chemically amplified, polynorbornene-based permanent dielectric have been investigated. The previously reported hexafluoroisopropanol norbornene and tert-butyl ester norbornene copolymer has been modified via two routes to improve the mechanical properties of the polymer and enable thick-film deposition. First, a third monomer, butyl norbornene (ButylNB) was added to the polymer backbone. The inclusion of 24 mol% ButylNB lowered the elastic modulus from 2.64 to 2.35 GPa and raised the dielectric constant from 2.78 to 3.48. The second approach added a lowmolecular weight, plasticizing additive in the copolymer formulation. Many additives were immiscible with the resin or did not affect the mechanical properties. Trimethyololpropane ethoxylate (TMPEO) was found to be a miscible additive that improved mechanical properties and could participate in crosslinking the final dielectric material. TMPEO interacted with the PAG, lowering its decomposition temperature. An optimal formulation and processing scheme were determined. A formulation with 10 pphr TMPEO was measured to have a dielectric constant of 2.94, an elastic modulus of 1.95 GPa, a sensitivity at 365 nm of 175 mJ/cm2, and a contrast of 4.36.
Rapid Coating Process Generates Omniphobic Dentures in Minutes to Reduce C. albicans Biofouling (2018)

Localized infections caused by biofilm formation on dentures pose a serious health risk for patients, especially the elderly, as they can lead to complications such as pneumonia. Daily enzymatic denture cleaners do not fully prevent biofilm formation on dentures. Here we developed a rapid coating process to apply a liquid repellent surface to dentures in ∼5 min and demonstrated a significant 225-fold reduction of <i>Candida albicans</i> adhesion over 6 days, compared to uncoated dentures. This rapid coating process could be applied to dentures and other dental devices chair-side and allow the research community to quickly and easily generate ominphobic surfaces.
Spatial and spectral filtering on focal plane arrays (2018)

This article describes new imaging capabilities and technologies developed for infrared focal plane arrays (FPAs) at SCD. One of the new technologies is the patterning of the back surface of the FPA, whose front surface is bonded to a silicon readout integrated circuit (ROIC). Another is the hybridization of a spectral filter to the same back surface. Increased image resolution has been achieved by using an opaque mask on the backside of the FPA with small central apertures. The reduced fill factor of the sensor leads to lower crosstalk between neighboring pixels and a higher Nyquist frequency. A highly detailed multi-mega pixel image is obtained when the sensor is micro-scanned relative to the imaging optics. Spectral filtering was achieved by hybridization of a designated filter to the backside of the FPA. The filter was glued to the FPA with high accuracy achieving single pixel resolution. System implementation of these SWIR sensor cameras has been demonstrated at imec and is reported in this paper. First results are reported for a continuously varying monolithic filter deposited onto the FPA, which has a high spectral dispersion. We report electro-optical measurements on several different sensors and describe some of their key parameters.
Contemporary utilization trends of systemic chemotherapy for upper tract urothelial carcinoma (UTUC). (2016)

441 Background: There is currently no consensus regarding the use of systemic therapy (ST) for surgically-treated patients with invasive UTUC. Using a large national cancer registry, our objective was to assess temporal trends in utilization of ST for stage II-IV UTUC undergoing definitive resection. Methods: The National Cancer Database (NCDB) was queried for all patients surgically treated (nephroureterectomy, segmental resection) for stage II-IV UTUC from 1998-2012. Temporal trends in receipt of ST [neoadjuvant (NAT), adjuvant (AT), or unknown timing (UKT)] were assessed using chi square analyses. After exclusion of patients receiving NAT or UKT, adjusting for patient and clinicopathologic characteristics, multivariable logistic models were used to examine the association between clinicopathologic characteristics and receipt of ST within 9 months of resection. Kaplan Meier analyses and stratified log-rank tests were performed comparing overall survival (OS) between patients receiving ST &lt; 9 months and those who did not. Results: Of 7,629 patients identified over the study period, 24.1% of patients surgically treated for stage II-IV UTUC received any ST (NAT: 1.44%, AT: 19.11%, UKT: 3.51%). Utilization of any ST significantly increased from 1998-2012 (20.2% vs. 28.7%, p &lt; 0.0001). Following adjustment, patients of increased age (61-70 years: OR 0.62 [CI 0.42-0.91], 71+ years: OR 0.26 [CI 0.17-0.38]) were less likely to receive ST, and patients with high grade (OR 2.46 [CI 1.95-3.09]), Stage III (OR 4.75 [CI 3.89-5.79]), and Stage IV (OR 9.37 [CI 7.49-11.74]) disease were more likely to be treated with ST. When restricted to stage III-IV disease, receipt of ST &lt; 9 months was significantly associated with improved OS after adjustment for age, grade, and charlson index (p &lt; 0.002). Conclusions: In hospitals reporting to the NCDB, while utilization has significantly increased from 1998-2012, less than one third of patients surgically treated for stage II-IV UTUC receive ST. In addition to unmeasured characteristics (decline of renal function following surgery), the lack of explicit guidelines and prospective evidence may contribute to limited use of systemic treatment.
