Wavelength Conversion of Real-Time 100-Gb/s POLMUX RZ-DQPSK (2009)

We present efficient wavelength conversion of a polarization-multiplexed RZ–DQPSK channel through cascading in a lithium niobate waveguide. BER measurements confirm that this is a promising technique for signal processing in high-bit-rate phase-modulated formats.
Convergent Planning (2016)

We propose a number of “divergence metrics” to quantify the robustness of a trajectory to state uncertainty for under-actuated or under-sensed systems. These metrics are inspired by contraction analysis and we demonstrate their use to guide randomized planners toward more convergent trajectories through three extensions to the kinodynamic RRT. The first strictly thresholds action selection based on these metrics, forcing the planner to find a solution that lies within a contraction region over which all initial conditions converge exponentially to a single trajectory. However, finding such a monotonically contracting plan is not always possible. Thus, we propose a second method that relaxes these strict requirements to find “convergent” (i.e., low-divergence) plans. The third algorithm uses these metrics for postplanning path selection. Two examples test the ability of these metrics to lead the planners to more robust trajectories: a mobile robot climbing a hill and a manipulator rearranging objects on a table.
Bone mineral content in Canadian Eskimos. (1975)

Bone mineral content was measured using direct photon absorptiometry in the forearm bones of Canadian Eskimos in the northern Foxe Basin. The sample consisted of 177 children, 92 young adults and 66 older adults. Canadian Eskimo children had slightly lower bone mineral (4 to 5% ) than Alaskan Eskimo children, and much lower bone mineral (10 to 13% than U.S. Whites), but these group differences were commensurate with the lower weights of the Canadian children. Throughout adulthood Canadian Eskimo bone mineral was almost identical on the average with values for Alaskan Eskimos; the major differences were lower mineral-width ratios in the Canadian Eskimo males over 50 years of age. Thus the Canadian EskimoWhite differences paralleled the relative deficit demonstrated for Alaskan Eskimos in a previous study, with the exception that relative bone loss in elderly males seemed even greater in the Canadian than in the Alaskan group. Eskimo males had a bone loss of about 10% a decade, and Eskimo females about 15% a decade, beginning in the forties; this was about 5% per decade for both sexes greater than the aging bone loss seen in U.S. Whites, and the onset of the bone loss was a decade sooner in Eskimo males. The bone mineral content of North Alaskan Eskimos has been examined by us using direct photon absorptiometry (Mazess, 1970; Mazess and Mather, 1974). It was shown that Alaskan Eskimo children had a 5 to 10% lower bone mineral content than U.S. Whites, but this was consistent with their smaller body and bone size. Young Alaskan Eskimo adults (20-39 years) of both sexes were similar in bone measurements to U.S. Whites, but after age 40 the Alaskan Eskimos of both sexes had a relative deficit of from 10 to 15% compared to White standards. Aging bone loss, which is common in many populations (Dequeker, 1972; Garn, 1970; Garn et al. 1967), had an earlier onset and greater intensity in the Alaskan Eskimos. Other investigations on the skeletal remains of the Sadlermiut Eskimo have suggested that an early and rapid bone loss might prevail in Canadian Eskimos as well 1 Cosmic Medicine Laboratory, Department of Radiology, University of Wisconsin Hospital, Madison, Wisconsin 53706.

Mazess and Warren E. Mather (Mazess and Jones, 1972). The Sadlermiut, a population living over the past hundred years on Southampton Island in the northern Hudson Bay area, showed reduced bone weights and densities in older versus younger adults. It was therefore of great interest to examine the skeletal status of living Canadian Eskimos. This report describes the results of absorptiometric bone mineral determinations of Eskimos living in the Foxe Basin area quite close to the Southampton home of the Sadlermiut.
[A Resected Case of Rectal Metastasis from Gastric Cancer]. (2019)

An 82-year-oldwoman previously underwent total gastrectomy for gastric cancer at the age of 75 years. After 7 years of follow-up, a colonoscopy was performedto investigate the cause of constipation, which revealedan irregularity in the rectal submucosa. A colonoscopy-guidedbiopsy showedpoorly differentiatedad enocarcinoma, andthe immunohistochemical staining pattern showedMUC2(-), MUC5AC(+), CDX2(+), andCA1 25(-). FDG-PET showedintense uptake only at the rectum. Thus, laparoscopic high anterior resection was performed. Pathological findings showed that poorly differentiated adenocarcinoma and signet-ring cell carcinoma hadd evelopedmainly in the submucosa. In comparison with the immunohistological features of the previous gastric cancer, the rectal tumor hadsimilar morphological characteristics. The definitive diagnosis was rectal metastasis from gastric cancer. She has remained recurrence-free in the 20 months since this operation.
Entropy‐Driven Selectivity for Chain Scission: Where Macromolecules Cleave (2015)

We show that, all other conditions being equal, bond cleavage in the middle of molecules is entropically much more favored than bond cleavage at the end. Multiple experimental and theoretical approaches have been used to study the selectivity for bond cleavage or dissociation in the middle versus the end of both covalent and supramolecular adducts and the extensive implications for other fields of chemistry including, e.g., chain transfer, polymer degradation, and control agent addition are discussed. The observed effects, which are a consequence of the underlying entropic factors, were predicted on the basis of simple theoretical models and demonstrated via high-temperature (HT) NMR spectroscopy of self-assembled supramolecular diblock systems as well as temperature-dependent size-exclusion chromatography (TD SEC) of covalently bonded Diels-Alder step-growth polymers.
Uplink Physical Layer Design (2009)

The LTE uplink is based on Single-Carrier Frequency Division Multiple Access (SC-FDMA). Like the OFDM scheme used in the downlink, this multiple access scheme has the advantage of achieving intra-cell orthogonality even in frequency-selective channels. Additionally, the Peak-to-Average Power Ratio is lower than in the case of pure multicarrier transmission like OFDM, thanks to the single carrier property of SC-FDMA whereby in each symbol period, all the transmitted subcarriers carry a component of all the modulated data symbols. This chapter describes the main features of time- and frequency-domain signal generation techniques applicable to SC-FDMA, including the localized and distributed resource allocation. The particular parameterization used in LTE is explained, including the options considered for d.c. subcarrier handling. Additionally, a discussion of the merits and demerits of pulse-shaping is also provided.
Anomaly detection in information streams without prior domain knowledge (2011)

A key goal of information analytics is to identify patterns of anomalous behavior. Such identification of anomalies is required in a variety of applications such as systems management, sensor networks, and security. However, most of the current state of the art on anomaly detection relies on using a predefined knowledge base. This knowledge base may consist of a predefined set of policies and rules, a set of templates representing predefined patterns in the data, or a description of events that constitutes anomalous behavior. When used in practice, a significant limitation of information analytics is the effort that goes into defining and creating the predefined knowledge base and the need to have prior information about the domain. In this paper, we present an approach that can identify anomalies in the information stream without requiring any prior domain knowledge. The proposed approach simultaneously monitors and analyzes the data stream at multiple temporal scales and learns the evolution of normal behavior over time in each time scale. The proposed approach is not sensitive to the choice of the distance metric and hence is applicable in various domains and applications. We have studied the effectiveness of the approach using different data sets.
Isoindigo-Based Donor–Acceptor Conjugated Polymers for Air-Stable Nonvolatile Memory Devices (2015)

Nonvolatile resistive memory devices based on a new low bandgap donor-acceptor (D-A) conjugated polymer, poly((<i>E</i>)-6,6'-bis(2,3-dihydrothieno[3,4-<i>b</i>][1,4]dioxine-5-yl)-1,1'-bis(2-octyldodecyl)-[3,3'-biindolinyi-dene]-2,2'-dione) (PIDED), which are fabricated and operated in ambient air, are reported. The D-A conjugated polymer is synthesized from 2,3-dihydrothieno[3,4-<i>b</i>][1,4]dioxine and isoindigo as an electron donor and an electron acceptor, respectively, using CH-arylation polymerization. The devices show nonvolatile, unipolar resistive switching behaviors with a high on/off current ratio (∼10<sup>4</sup>), excellent endurance cycles (>200 cycles), and a long retention time (>10<sup>4</sup> s) in ambient air. These properties remain stable in ambient air over one year, demonstrating that the device performance is significantly unaffected by exposure to air as the isoindigo has strong electron-withdrawing character and the PIDED exhibits a high degree of crystallinity. This study may pave the way for use of practical nonvolatile organic memory devices operating in ambient air.
Segmented-core single-mode fiber optimized for bending performance (1988)

Both macrobending and microbending losses have been found to depend mainly on the mode field diameter of the fiber.1 In fibers of simple step-index design, it is possible to decrease the mode field diameter by increasing the delta of the core region; however, for large deltas, this can result in an undesirable increase in the cutoff and/or zero dispersion wavelengths. Using a segmented core design similar to that described by Bhagavatula et al.,2 the dependence of the cutoff and zero dispersion wavelengths on the delta of the core may be lessened. Thus a fiber with the same cutoff and zero dispersion wavelengths as a simple step-index design may be made with a lower mode-field diameter and hence a lower bending loss.
Inequity aversion resolves intertemporal social dilemmas (2018)

Groups of humans are often able to find ways to cooperate with one another in
complex, temporally extended social dilemmas. Models based on behavioral
economics are only able to explain this phenomenon for unrealistic stateless
matrix games. Recently, multi-agent reinforcement learning has been applied to
generalize social dilemma problems to temporally and spatially extended Markov
games. However, this has not yet generated an agent that learns to cooperate in
social dilemmas as humans do. A key insight is that many, but not all, human
individuals have inequity averse social preferences. This promotes a particular
resolution of the matrix game social dilemma wherein inequity-averse
individuals are personally pro-social and punish defectors. Here we extend this
idea to Markov games and show that it promotes cooperation in several types of
sequential social dilemma, via a profitable interaction with policy
learnability. In particular, we find that inequity aversion improves temporal
credit assignment for the important class of intertemporal social dilemmas.
These results help explain how large-scale cooperation may emerge and persist.
A VQ-based fast face recognition algorithm using optimized codebook (2008)

In this paper, we present a VQ-based fast face recognition algorithm using an optimized codebook. Previously, Chen et al. [16] proposed a novel codebook design method based on the systematic classification and organization of code patterns abstracted from facial images for reliable face recognition. In this paper, an improved codebook design method is proposed. Combined by a systematically organized codebook based on the classification of code patterns and another codebook created by Kohonen’s Self-Organizing Maps (SOM), an optimized codebook consisted of 2×2 codevectors for facial images is generated. We demonstrate the performance of our algorithm using publicly available AT&T database containing variations in lighting, posing, and expressions. Compared with the algorithms employing original codebook or SOM codebook separately, experimental results show face recognition using the optimized codebook is more efficient. The highest average recognition rate of 98.2% is obtained for 40 persons’ 400 images of AT&T database. A table look-up (TLU) method is also proposed for the speed up of the recognition processing in this paper. By applying this method in the quantization step, the total recognition processing time achieves only 28 msec, enabling real-time face recognition.

Experience With Endovascular Abdominal Aortic Aneurysm Repair in Nonagenarians (2006)

Endovascular AAA repair in nonagenarians is associated with a high rate of technical success and relatively low morbidity rate. Survival times following successful hospital discharge are significant. Suitable patients over 90 years of age may benefit from an endovascular AAA repair.
Teaching Manufacturing Process Design as a Means for Competitive Advantage in Chemical Process Industries (2020)

While manufacturing engineering curricula rightly borrows from both industrial engineering and mechanical engineering curricula, there is an increasing awareness in education that manufacturing engineering should be taught as a distinguishable engineering design activity. Doing so recognizes the potential for manufacturing engineering to drive deep sources of competitive advantage in product development through manufacturing innovation. This paper provides details on a pedagogy used to educate chemical engineers, without a background in discrete part manufacturing, about a design-oriented approach to manufacturing process selection, in the context of a four-day educational workshop on advancing chemical process innovations to market. The engineers were taught this manufacturing process design method in the context of designing and innovating chemical reactor components. E-books, in-lab process demonstrations, and spreadsheet cost models were all used as pedagogical tools to teach the method through a sequence of lectures, tutorials/laboratories, and class exercises. Survey results show that the chemical engineering participants scored the segment on selecting manufacturing processes higher than any other innovation segment in the four-day workshop. In-laboratory process demonstrations were scored high suggesting value in exposing chemical engineers to physical manufacturing processes during the workshop.
An EFSUMB Introduction into Dynamic Contrast- Enhanced Ultrasound (DCE-US) for Quantification of Tumour Perfusion Einführung des "Dynamic Contrast-Enhanced Ultrasound (DCE-US)" zur Quantifizierung der Tumorperfusion, EFSUMB-Statement (2012)

Dynamic Contrast Enhanced Ultrasound (DCE-US) is an imaging technique that utilizes microbubble contrast agents in diagnostic ultrasound. The EF- SUMB guidelines published in 2004, updated in 2008 and 2011 focused on the use of DCE-US, in- cluding essential technical requirements, training, investigational procedures and steps, guidance on image interpretation, established and recommen- ded clinical indications and safety considerations. However the quantification of images acquired with ultrasound contrast agents (UCAs) is not discussed in the guidelines. The purpose of this EFSUMB document is to provide some recommen- dations and descriptions of the quantification of ultrasound images, technical requirements for analysis of time-intensity curves (TICs), methodol- ogy for data analysis, and interpretation of the re- sults.

GEO Satellite Feeder Links and Terrestrial Full-Duplex Small Cells: A Case for Coexistence (2016)

The demand for wider bandwidths has motivated the need for wireless systems to migrate to higher frequency bands. In line with this trend is an envisaged deployment of Ka-band (or mmWave) cellular infrastructure. Further, to improve the spectral efficiency, developing full-duplex radio transceivers is gaining momentum. In view of this move, the paper proposes the possibility of reusing the satellite feeder uplink band in the full-duplex small cells. The motivation for such a reuse is two-fold :(a) there is virtually no interference from the small cells to the incumbent in-orbit satellite receiver, and (b) directive feeder antennas, with possibly additional isolation and processing causing negligible interference to the small cells. The presented interference analysis clearly supports the proposed coexistence.
Performance Evaluation of CBGNR, CBDGR Routing Protocol in WSN (2023)

Increasing the throughput of a wireless sensor network is a descriptive term for an efficient routing technique that creates an efficient network. Wireless Sensor Network is used to develop an efficient and authentic wireless network model. A WSN obtains information from a large network, where a small sensor node collects information from its chain and sends data to the master node. The lifetime of nodes depends on battery power and WSN data collection in chain form. In a wireless environment, it is not possible to supply extra power or recharge nodes. So here we will use a gateway node that has uninterrupted power. In the WSN routing protocol, it takes extra energy when a node changes its position in the network, making the throughput poor. Wireless sensor network WSN has some reason to reduce throughput and packet delivery. There are some reasons in the network for reducing throughput, such as the multi-hop path, the maximum number of hops, the maximum distance for each hop, and load density. In this paper, we have proposed an energy-efficient chainbased routing technique that minimizes the above problem. Our purpose-built technique achieves slightly better performance than both in terms of throughput, packet delivery, and power consumption
Data–driven Neural Feedforward Controller Design for Industrial Linear Motors (2019)

In this paper we consider the problem of feedforward controller design for industrial linear motors. These motors are safety-critical high-precision mechatronics systems that pose stringent requirements on the feedforward design: safe and predictable behavior for the desired motion profiles, tracking performance within the 10μm range in the presence of nonlinear friction and real-time implementation within the 1ms range. We investigate and compare several possibilities to design data- driven feedforward controllers using neural networks (NN) and we show that a two-step inverse estimation method is the most suitable approach, due to robustness to noisy data. We also show that basic knowledge about the system dynamics and the friction behavior can be exploited to design neural feedforward controllers with a simple structure, suitable for real-time implementation in industrial linear motors. The developed data-driven neural feedforward controllers are tested and compared with standard mass-acceleration feedforward and iterative learning controllers in realistic simulations.
