Learning Crowdsourced User Preferences for Visual Summarization of Image Collections (2013)

In this paper we propose a novel approach to selecting images suitable for inclusion in the visual summaries. The approach is grounded in insights about how people summarize image collections. We utilize the Amazon Mechanical Turk crowdsourcing platform to obtain a large number of manually created visual summaries as well as information about criteria for image inclusion in the summary. Based on these large-scale user tests, we propose an automatic image selection approach, which jointly utilizes the analysis of image content, context, popularity, visual aesthetic appeal as well as the sentiment derived from the comments posted on the images. In our approach we do not describe images based on their properties only, but also in the context of semantically related images, which improves robustness and effectively enables propagation of sentiment, aesthetic appeal as well as various inherent attributes associated with a particular group of images. We discuss the phenomenon of a low inter-user agreement, which makes an automatic evaluation of visual summaries a challenging task and propose a solution inspired by the text summarization and machine translation communities. The experiments performed on a collection of geo-referenced Flickr images demonstrate the effectiveness of our image selection approach.
Designing an Adaptive Automation System for Human Supervision of Unmanned Vehicles: A Bridge from Theory to Practice (2008)

Careful consideration must be given to the implementation of automation into complex systems. Much research in adaptive automation has identified challenges for system implementation. A key focus of this research has surrounded the methods of automation invocation including critical events, measurement, and modeling techniques. However, little consideration has been given to selecting and implementing appropriate techniques for a given system as a guide to designers of adaptive automation. This paper proposes such a methodology. We demonstrate the use of this methodology by describing a case study about a system designed to support effective communication and collaboration between the commander and vehicle operator in an unmanned aerial vehicle (UAV) system.
Low-Complexity Polynomial Channel Estimation in Large-Scale MIMO With Arbitrary Statistics (2014)

This paper considers pilot-based channel estimation in large-scale multiple-input multiple-output (MIMO) communication systems, also known as “massive MIMO,” where there are hundreds of antennas at one side of the link. Motivated by the fact that computational complexity is one of the main challenges in such systems, a set of low-complexity Bayesian channel estimators, coined Polynomial ExpAnsion CHannel (PEACH) estimators, are introduced for arbitrary channel and interference statistics. While the conventional minimum mean square error (MMSE) estimator has cubic complexity in the dimension of the covariance matrices, due to an inversion operation, our proposed estimators significantly reduce this to square complexity by approximating the inverse by a L-degree matrix polynomial. The coefficients of the polynomial are optimized to minimize the mean square error (MSE) of the estimate. We show numerically that near-optimal MSEs are achieved with low polynomial degrees. We also derive the exact computational complexity of the proposed estimators, in terms of the floating-point operations (FLOPs), by which we prove that the proposed estimators outperform the conventional estimators in large-scale MIMO systems of practical dimensions while providing a reasonable MSEs. Moreover, we show that L needs not scale with the system dimensions to maintain a certain normalized MSE. By analyzing different interference scenarios, we observe that the relative MSE loss of using the low-complexity PEACH estimators is smaller in realistic scenarios with pilot contamination. On the other hand, PEACH estimators are not well suited for noise-limited scenarios with high pilot power; therefore, we also introduce the low-complexity diagonalized estimator that performs well in this regime. Finally, we also investigate numerically how the estimation performance is affected by having imperfect statistical knowledge. High robustness is achieved for large-dimensional matrices by using a new covariance estimate which is an affine function of the sample covariance matrix and a regularization term.

Laminin-induced retinoblastoma cell differentiation: possible involvement of a 100-kDa cell-surface laminin-binding protein. (1992)

Gene and protein expression of Y-79 retinoblastoma cells growing on poly(D-lysine) is switched from a photoreceptor-like to a conventional neuron-like pathway by the basement membrane glycoprotein laminin. Unlike other cell systems where laminin influences differentiation, Y-79 cells can neither attach to nor chemotactically respond to laminin. However, laminin increases attachment to poly(D-lysine). The laminin effects therefore seem to occur via an adhesion- and chemotaxis-independent mechanism. Moreover, these tumor cells do not exhibit high-affinity laminin binding, having only a single binding site of intermediate affinity. Laminin-Sepharose affinity chromatography of Y-79 cell surface proteins labeled with 125I revealed a single major radiolabeled 100-kDa protein eluted by 20 mM EDTA, with an electrophoretic behavior different from that of integrins. No other proteins were eluted under more stringent conditions. This material, which we call LBM-100 (100-kDa laminin-binding molecule), may be a "differentiative" laminin-binding protein through which laminin influences gene expression and development independently of attachment.
The Management of High Risk Prostate Cancer (2003)

Although analysis of current literature revealed that patients who have recurrence after primary therapy would benefit from radiotherapy, hormonal therapy, chemotherapy or a combination of therapies, additional prospective randomized studies are needed to support these findings.
Learning to score and summarize figure skating sport videos. (2018)

This paper focuses on fully understanding the figure skating sport videos. In particular, we present a large-scale figure skating sport video dataset, which include 500 figure skating videos. On average, the length of each video is 2 minute and 50 seconds. Each video is annotated by three scores from nine different referees, i.e., Total Element Score(TES), Total Program Component Score (PCS), and Total Deductions(DED). The players of this dataset come from more than 20 different countries. We compare different features and models to predict the scores of each video. We also derive a video summarization dataset of 476 videos with the ground-truth video summary produced from the great shot. A reinforcement learning based video summarization algorithm is proposed here; and the experiments show better performance than the other baseline video summarization algorithms.
Heuristics for weighted perfect matching (1980)

The problem of finding near optimal perfect matchings of an even number n of vertices is considered. When the distances between the vertices satisfy the triangle inequality it is possible to get within a constant multiplicative factor of the optimal matching in time O(n2 log K) where K is the ratio of the longest to the shortest distance between vertices. Other heuristics are analyzed as well, including one that gets within a logarithmic factor of the optimal matching in time O(n2 log n). Finding an optimal weighted matching requires t(n3) time by the fastest known algorithm, so these heuristics are quite useful. When the n vertices lie in the unit (Euclidean) square, no heuristic can be guaranteed to produce a matching of cost less than [equation] in the worst case. We analyze various heuristics for this case, including one that always produces a matching costing at most [equation]. In addition, this heuristic also finds a traveling salesman tour of the n vertices costing at most [equation]. A different one of the heuristics analyzed produces asymptotically optimal results. It is also shown that asymptotically optimal traveling salesman tours can be found in O(n log n) time in the unit square.
ZOOMM (2013)

We explore the challenges in expressing and managing concurrency in browsers on mobile devices. Browsers are complex applications that implement multiple standards, need to support legacy behavior, and are highly dynamic and interactive. We present ZOOMM, a highly concurrent web browser engine prototype and show how concurrency is effectively exploited at different levels: speed up computation performance, preload network resources, and preprocess resources outside the critical path of page loading. On a dual-core Android mobile device we demonstrate that ZOOMM is two times faster than the native WebKit based browser when loading the set of pages defined in the Vellamo benchmark.
Turbulent ‘polarization’ terms and the Balescu–Lenard operator (1982)

Certain unfamiliar terms in renormalized plasma turbulence theory are interpreted in terms of the familiar physics of the Balescu–Lenard collision operator. Specifically, it is argued that the so-called polarization parts of the operator which renormalizes the particle propagator are related to fluctuations of the Fokker–Planck coefficient which describes polarization drag, and to fluctuations of the effective dielectric function of the medium.
Spectral estimation in unevenly sampled space of periodically expressed microarray time series data (2007)

Preliminary observations on inducing homozygous gynogenesis in Northern pike [Esox lucius] using pressure shock (2004)

We induced homozygous gynogenesis in Northern pike (Esox lucius L.). The eggs obtained from two females and inseminated with UV inactivated milt were subjected to a pressure shock. The shock (600 atm, 3 min duration) was applied 60, 75, 90, 105, 120 or 135 min after activation of gametes. Application of the pressure shock resulted in interruption of the first mitotic division and gynogenetic larvae were obtained. The best results (5.20 0.7% of survival, expressed as average SD) were observed when the eggs from the first female (A) were subjected to a pressure shock 75 min after insemination. Shock applied 90 min after activation resulted in 3.51 2.4% of gynogenetic individuals. Pressure treatments applied 105, 120 or 135 min were ineffective. The results demonstrate that pressure shock can be applied to induce homozygous development in Northern pike. 1
The ageing athlete: screening prior to vigorous exertion in asymptomatic adults without known cardiovascular disease (2009)

The exercise electrocardiogram (ECG) is widely considered the best available test for screening asymptomatic adults without known cardiovascular (CV) disease prior to initiating a vigorous exercise programme due to its prognostic value, widespread availability and low cost. Observational studies have demonstrated an increased relative risk of CV events with positive screening exercise ECG tests in men with diabetes, advanced age, or multiple cardiac risk factors. Recent observational studies have not demonstrated similar prognostic value for exercise ECG testing in asymptomatic healthy women. Despite the predictive ability of exercise ECG testing in several groups, there have been no studies demonstrating a significant impact of screening on morbidity and mortality in completely asymptomatic patients, leading to significant discordance in consensus guidelines on screening. One prospective observational study is ongoing in Italy that may for the first time demonstrate the ability to decrease incident CV events using preparticipation screening exercise ECG testing in adult athletes with targeted exclusion from athletics. Until more conclusive data is available the authors currently recommend screening exercise ECG testing in asymptomatic men with diabetes and asymptomatic men over age 45 with two or more CV risk factors prior to initiating a vigorous exercise programme. Consideration should also be given to screening asymptomatic patients younger than 45 with particularly strong risk factor exposure or elderly patients with fewer than two risk factors.
The web survey network of sudden infant death syndrome and apparent life-threatening events in the Emilia-Romagna region (2004)

To survey epidemiology and to study the etiology of sudden infant death syndrome (SIDS) and apparent life threatening events (ALTE) in Emilia-Romagna, a web network was constituted. A regional supervisor and a steering committee plan the action of district and local co-ordinators. They keep contact with the Regional Office of Health Services. District and local co-ordinators collect clinical and laboratory and, in case of SIDS, also autopsy data. Records are communicated to the Regional Supervising Center by on-line software. From these data, future planning of care and of mass information as well as auditing of their efficacy can be carried out. The characteristics of the network that has just started to collect data, as well its future developmental aspects, are discussed.

Multilayer Perceptron Adaptive Dynamic Control for Trajectory Tracking of Mobile Robots (2006)

This paper presents a novel functional-adaptive dynamic controller for trajectory tracking of nonholonomic wheeled mobile robots. The controller is developed in discrete-time and employs a multilayer perceptron neural network for the estimation of the robot's nonlinear dynamic functions, which are assumed to be completely unknown. On-line weight tuning is achieved by employing the extended Kalman filter algorithm, based on a specifically formulated stochastic inverse dynamic identification model of the mobile base. A discrete-time dynamic control law employing the estimated functions is proposed and cascaded with a trajectory tracking kinematic controller. The performance of the complete system is analysed and compared by realistic simulations
ANODIZED LAYERS ON TITANIUM AND TITANIUM ALLOY ORTHOPEDIC MATERIALS FOR ANTIMICROBIAL ACTIVITY APPLICATIONS (1992)

ABSTRACT The development of a post operative infection following the implantation of a foreign material, such as a total joint prosthesis, is one of the most feared complications in orthopedic surgery. Prevention of such bacterial infections is best accomplished through the delivery of antibiotics as close to the implant as possible. A novel method has been developed to attach, retain and release antibiotics from titanium based materials. This technique consists of forming porous surface coatings by anodizing and using the surface chemical properties of the oxide coatings to attach antibiotics. Coatings with pores in the size range 0.1 to 10 urn have been formed in acid as well as basic solutions. The thickness, stoichiometry and morphology of the coatings have been characterized by Rutherford backscattering spectrometry and electron spectroscopy techniques. The isoelectric point of the coatings has been measured by a streaming potential technique. The attachment and retainment of gentamicin sulfate, a cationic antibiotic, to the coatings has been investigated using microbiological and streaming potential methods. In vitro test results have shown that the duration of antimicrobial activity on the surface of anodized materials is dependent on the porosity and isoelectric point of the coatings. Using microporous oxide coatings, it has been found that antimicrobial activity could be retained for almost two weeks.
A unified framework for mode filtering and the maximum <i>a posteriori</i> mode filter (1998)

A unified framework is presented for examining the performance of linear mode filtering algorithms. Two common mode filters, samples of the mode shapes and the pseudo-inverse of the mode shapes, are presented in this framework as a tradeoff between sensitivity to other modes and sensitivity to white noise. The maximum a posteriori mode filter is presented as an alternative which gracefully transitions between these extremes, and attains the minimum mean squared error when the modes to be estimated are well modeled as samples of a Gaussian random process. Numerical simulations in both shallow and deep water environments confirm the analytically derived properties of these mode filters.
Quality Test of Timed-Release Form of Iron Preparations (1977)

A test method to check the dissolution pattern of timed-release preparations is described. Rotation method of U. S. P. XIX was used as a dissolution tester. First, 900ml of dissolution medium containing 2.0ml of diluted HCl and 2.0g of NaCl in 1000ml was used. By exchanging 5 ml each of the medium with the same volume of the second solution (disintegration, J. P. IX) at the intervals of 10 min for the first 1hr and of 15 min for the subsequent 4 hrs, pH of the medium was designed to change gradually from 2.3 to 3.5 in the first 150 min, rapidly from 3.5 to 5.7 in the following 30 min, and gradually up to 6.5 after 300 min, volume of the medium being kept at a fixed level. The rotation rate of basket was 100 rpm. Under the above condition, dissolution curves of iron preparations in 5 dosage forms of different manufacturers were compared. Maximum dissolution percentage varied from 27 to 92% among samples. At about pH 4, precipitates were formed in the medium as a result of the decrease of solubility of iron into the medium. The rates of dissolution of 6 dosage forms in the same lot number in the first 120 min varied largely, from 5 to 20%.

Who and What Is a Mother? Maternity, Responsibility and Liberty (2012)

Motherhood is no longer a clear-cut concept. Is it a mere biological fact, or does it require a volitional component? This question is answered differently throughout Europe. The French regime of accouchement sous X is more oriented towards the second option. Conversely, the English system identifies parturition as the exclusive determinant for defining legal motherhood. This debate has an impact on the resolution of another issue, namely whether an individual, preeminently a child, has a right to know about his/her origins. The recognition of an absolute right of a woman to give birth anonymously evidently contravenes Franceâs obligation to protect the right to know oneâs origins, as enshrined in the UNCRC as well as in the ECHR. Furthermore, despite its laudable purpose, the French regime has proved unable to prevent tragic events, such as infanticide, abandonment and abortion. But does English law offer a solution that is more respectful of childrenâs rights? To all appearances, it does, but not substantially. The denial of accouchement sous X should not be viewed as enhancing the overall protection of childrenâs rights in England. By providing abortion on demand, a womanâs right to renounce maternity is fully protected and, therefore, the legalization of anonymous birth would be superfluous. In light of the complexity of the issue whether a child has the right to know his/her origins, categorical positions are not appropriate, since they implicitly postulate hierarchies of rights. To the contrary, the acknowledgement of the competing rights as equally fundamental makes it possible to achieve a fair equilibrium between the interests of all parties involved. In this balancing exercise, the reconceptualization of identity as child-centered has the potential to overcome the culturally-constructed dichotomy of biological connections/social bonds and, therefore, to realize the best interests of every child.
New concept combines offshore wind farms, mussel cultivation (2007)

Wind energy is the world’s most dynamically growing energy source. The first initiative toward an economy based on renewable energy resources in Germany was set by the governmental decision to gradually reduce the use of nuclear energy. Plans were promoted to implement large wind farms far out in the German North Sea and large areas within the coastal sea. As wind energy operations only take place above water surfaces, the idea was born to co-use these areas for offshore aquaculture.
Seasonal trends and nightly fluctuations of SWIR air-glow irradiance (2011)

It is well known that luminance from photo-chemical reactions of hydroxyl ions in the upper atmosphere (~85 km altitude) produces a significant amount of night time radiation in the short wave infra-red (SWIR) band with wavelength between 0.9 and 1.7 μm. This air glow has been proposed as an illumination source for obtaining imagery in the dark of night. By examining short term nightly fluctuations and long term seasonal trends in the ground level irradiance we hope to determine the source reliability for night time low light surveillance and imaging.
