Non-iterative approach for fast and accurate vanishing point detection (2009)

We present an algorithm that quickly and accurately estimates vanishing points in images of man-made environments. Contrary to previously proposed solutions, ours is neither iterative nor relies on voting in the space of vanishing points. Our formulation is based on a recently proposed algorithm for the simultaneous estimation of multiple models called J-Linkage. Our method avoids representing edges on the Gaussian sphere and the computations and error measures are done in the image. We show that a consistency measure between a vanishing point and an edge of the image can be computed in closed-form while being geometrically meaningful. Finally, given a set of estimated vanishing points, we show how this consistency measure can be used to identify the three vanishing points corresponding to the Manhattan directions. We compare our algorithm with other approaches on the York Urban Database and show significant performance improvements.
Inheritance of a Radiation-induced Light Sensitive Mutant of Cucumber1 (1972)

Abstract A mutation with a pleiotropic effect was obtained from progeny of cucumber seed exposed to 16,000 rads of gamma radiation. Mutants were marked in the seedling stage by pale color and reduced size of cotyledons. Leaves of mutant plants had normal color but the plants grew slowly. Height of plant, length of internodes and petioles, size of flower, leaves, and fruit were noticeably smaller than normal plants. The mutation was recessive and monogenic. Maternal effects were not evident and no linkage was detected with a gene affecting cotyledon bitterness. The mutants were affected by high light intensity, and regardless of plant age, became senescent and died within 7 days following exposure to full sunlight. The gene is designated ls (light sensitive).

An overview of the roles and responsibilities of Chinese medical colleges in body donation programs (2013)

The use of human tissue is critical for gross anatomy education in the health professions. Chinese medical colleges have faced a shortage of anatomical specimens over the past decade. While body donation plays an important role in overcoming this gap, this practice has only recently been introduced in China, and the donation rate is relatively low and fraught with a number of difficulties. In the past, traditional Chinese culture focused on preserving the human body intact, which often limited body donation. In recent years, the public has become more open toward body donation. At Nanjing Medical University, only 20 bodies were donated in 2001. After the university became involved in an organized body donation program, this number increased to 70 donated bodies per year (2007 to 2012). This article describes and reviews Chinese medical colleges as a special case study among body donation programs, particularly in terms of the multiple responsibilities and roles that such institutions must assume in the course of adopting these programs. Medical colleges in China must serve as advocates, coordinators, builders, managers, educators, and beneficiaries in undertaking body donation programs. It is important for medical colleges to recognize these pluripotent roles and educate the public in order to promote body donation programs. This case study may also effectively guide and encourage Chinese medical colleges in refining their own body donation programs in the future.
Locating and Tracking of Human Faces with Neural Networks (1994)

Effective Human--to--Human communication involves both auditory and visual modalities, providing robustness and naturalness in realistic communication situations. Recent efforts at our lab are aimed at providing such multimodal capabilities for human-machine communication as well by introducing gesture, character and speech recognition, eye-tracking and lipreading. Most of the visual modalities require a stable image of a speaker&apos;s face. In this technical report a connectionist face tracker is proposed that manipulates camera orientation and zoom, to keep a person&apos;s face located at all times in an image sequence. The system operates in real time and can adapt rapidly to different lighting conditions, different cameras and faces, making it robust against environmental variability. Extensions and integration of the system with a multimodal interface will be presented.

An Approach for Cloud Resource Risk Prediction (2012)

The resource risk management is a key issue in cloud computing, which is directly related to the reliability and security of the cloud computing platform. In the cloud bank model [1], almost all resources come from messes of cloud resource providers, who are distributed on the Internet. This feature caused some special resource risk types that didn‘t occur in the enterprise private cloud, such as the resource default risk caused by people or machines. Analyzed the features of cloud computing and the cloud bank model, this paper delivers a cloud resource risk prediction model, which is based on mathematical statistics. This method advances the risk management strategy from the accident response to the beforehand prediction.
Challenging legacies: rearticulating 'honour' and 'the child' (2011)

In this paper I trace the combined origins and variations of the trope of ‘honour’ and the figure of ‘the child’: from medieval Europe to contemporary postcolonial contexts. What remains constant are the cultural and political agendas fulfilled in the name of the child, in particular as a warrant fuelling religious and racialised persecution. This background to child protection poses considerable challenges to educationalists and advocates for children. However, engaging with these gives rise, I argue, to positive strategies for change: firstly, to illuminate the wider agendas constellated around ‘the child’ – and so better identify whose ‘honour’ (and whose interests) is at stake; secondly, to attend to the gendered and cultural dynamics that surround children, including their interplay with questions of national identity and cultural reproduction; thirdly, a feminist and social justice perspective to questions of culture and honour neither exonerates violence in the name of cultural respect, nor ignores the complexity of power relations through which such evaluations are made.
Optimization of the LCLS X-Ray FEL Output Performance in the Presence of Strong Undulator Wakefields (2006)

The Linac Coherent Light Source (LCLS) Free-Electron Laser will operate in the wavelength range of 1.5 to 15 Angstroms. Energy loss due to wakefields within the long undulator can degrade the FEL process by detuning the resonant FEL frequency. The wakefields arise from the vacuum chamber wall resistivity, its surface roughness, and abrupt changes in its aperture. For LCLS parameters, the resistive component is the most critical and depends upon the chamber material (e.g. Cu) and its radius. To study the expected performance in the presence of these wakefields, we make a series of start-to-end simulations with tracking codes PARMELA and ELEGANT and time-dependent FEL simulation codes Genesis 1.3 and Ginger. We discuss the impact of the wakefield on output energy, spectral band-width, and temporal envelope of the output FEL pulse, as well as the benefits of a partial compensation obtained with a slight z dependent taper in the undulator field. We compare these results to those obtained by decreasing the bunch charge or increasing the vacuum chamber radius. We also compare our results to those predicted in concurrent analytical work.
Paraphrase Generation for Semi-Supervised Learning in (2019)

Semi-supervised learning is an efficient way to improve performance for natural language processing systems. In this work, we propose Para-SSL, a scheme to generate candidate utterances using paraphrasing and methods from semi-supervised learning. In order to perform paraphrase generation in the context of a dialog system, we automatically extract paraphrase pairs to create a paraphrase corpus. Using this data, we build a paraphrase generation system and perform one-to-many generation, followed by a validation step to select only the utterances with good quality. The paraphrase-based semi-supervised learning is applied to five functionalities in a natural language understanding system. Our proposed method for semi-supervised learning using paraphrase generation does not require user utterances and can be applied prior to releasing a new functionality to a system. Experiments show that we can achieve up to 19% of relative slot error reduction without an access to user utterances, and up to 35% when leveraging live traffic utterances.
Studies on Isocyanides and Related Compounds: A Novel Synthesis of Pyrroles via Ugi Reaction (1994)

A series of N-substituted 1,3-diaryl-4-cyano-2,5-dihydro-5-oxopyrrole-2-carboxamides 9 is obtained by reacting arylglyoxal anils 6 with isocyanides 3 and cyanoacetic acid (2). Compounds 9 react quickly with diazomethane to give N-substituted 1, 3-diaryl-4-cyano-5-methoxypyrrole-2-carboxamides 12.
Derivative Traces in Infrared Fourier Transform Spectroscopy (1970)

The principles of derivative spectrophotometry have been known for many years, and a variety of instrumentation for producing the first and higher differentials of absorption spectra has been described.1–21 However, despite the advantages of the techniques for intensifying minor changes in spectra, the separation of overlapping bands, or for band sharpening, derivative traces have not been used to a significant extent in infrared spectroscopy.
¿Qué hace que un sujeto se convierta en testigo?: Una reflexión sobre la noción de carrera testimonial (2018)

En el año 2011, los investigadores Jacques Walter y BéatriceFleury, de la Universidad de Metz (Francia), iniciaron un programa de investigación internacional e interdisciplinario titulado “Carreras testimoniales. Los [procesos de] ‘devenir-testigos’ de conflictos de los siglos XX y XXI”. El programa reunió a académicos de Francia, Alemania, España, Ucrania, Armenia, Ruanda, Canadá y Argentina para pensar de qué manera las sociedades elaboraban sus memorias ante conflictos sangrientos y hechos traumáticos. El texto que se publica aquí, traducido por Antonia García Castro, sintetiza los resultados del mencionado proyecto. En particular, permite presentar la noción de “carrera testimonial”, examinando sus posibilidades y límites para la investigación.
Biological therapies for inflammatory bowel disease: controversies and future options (2009)

Over the last few years, advances in understanding the pathogenesis of inflammatory bowel disease, together with progress in biotechnology, have led to the availability of several biological drugs that have dramatically changed the therapeutic approach to these disorders. Indeed, several molecules targeting crucial inflammatory cytokines, blocking T-cell activation/proliferation or the recruitment of inflammatory cells into the inflamed bowel, have been discovered and commercialized. However, the increasing use of biological agents has raised some concerns regarding their short- and long-term safety. This review offers a critical evaluation of the efficacy and safety of biological agents in the management of both Crohn's disease and ulcerative colitis. In addition, promising therapeutic options are discussed.
Melatonin effects on sleep, mood, and cognition in elderly with mild cognitive impairment (1998)

The effects of immediate-release melatonin on circadian rest-activity profiles, cognition, and mood were investigated in ten elderly individuals with self-reported sleep-wake disturbances. Melatonin (6 mg), administered 2 hr before habitual bedtime, enhanced the rest-activity rhythm and improved sleep quality as observed in a reduction in sleep onset latency and in the number of transitions from sleep to wakefulness. However, total sleep time was not significantly increased nor was wake within sleep significantly reduced. The ability to remember previously learned items improved along with a significant reduction in depressed moods. No side effects or contraindications were reported by any of our participants during the 10 day trials. These data suggest that melatonin can safely improve some aspects of sleep, memory, and mood in the elderly in short-term use.
On A Design of Crossroad Switches for Low-Power On-Chip Communication Architectures (2006)

As the number of cores on a chip increases, power consumed by the communication structures takes significant portion of the overall power-budget. We first propose a novel 2D segmented interconnect architecture, which uses crossroad switches to dynamically construct a dedicated communication path between any two cores. We then present two application-specific bus operation schemes (normal mode and lease line mode). Each switch may operate with a "lease line", which can dynamically offer a dedicated path between two highly-communicative cores for a specific period according to the application characteristics. Finally, we present a concept of wrappers to help designers use our crossroad architecture as communication backbone. We take the JPEG and MPEG4 reference codes as our case studies and experimental results show the power consumptions can be saved if we dynamically control NoC switches when the behavior of the embedded software is well-known.
All Chemical Vapor Deposition Growth of MoS<sub>2</sub>:h-BN Vertical van der Waals Heterostructures (2015)

Vertical van der Waals heterostructures are formed when different 2D crystals are stacked on top of each other. Improved optical properties arise in semiconducting transition metal dichalcogenide (TMD) 2D materials, such as MoS2, when they are stacked onto the insulating 2D hexagonal boron nitride (h-BN). Most work to date has required mechanical exfoliation of at least one of the TMDs or h-BN materials to form these semiconductor:insulator structures. Here, we report a direct all-CVD process for the fabrication of high-quality monolayer MoS2:h-BN vertical heterostructured films with isolated MoS2 domains distributed across 1 cm. This is enabled by the use of few-layer h-BN films that are more robust against decomposition than monolayer h-BN during the MoS2 growth process. The MoS2 domains exhibit different growth dynamics on the h-BN surfaces compared to bare SiO2, confirming that there is strong interaction between the MoS2 and underlying h-BN. Raman and photoluminescence spectroscopies of CVD-grown MoS2 are compared to transferred MoS2 on both types of substrates, and our results show directly grown MoS2 on h-BN films have smaller lattice strain, lower doping level, cleaner and sharper interfaces, and high-quality interlayer contact.
High-order perceptrons for decoding error-correcting codes (2003)

The authors prove that the single-error correcting (2/sup n/-1, 2/sup n/-1-n) Hamming code and its extended single-error correcting/double-error detecting (2/sup n/, 2/sup n/-1-n) code can be decoded by low-complexity single-layer perceptrons which use high-order polynomials as their discriminant functions. It is illustrated that multiple-error correcting codes can be decoded by two-layer networks with high-order perceptrons in the first layer and linear perceptrons in the second layer.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Energy-efficient data centers: a close-coupled row solution. (2008)

The predominant architecture for cooling data centers since the inception of the mainframe has been raised floor air delivery from perimeter computer room air handlers (CRAH). In this approach, CRAHs are placed around the perimeter of the room, and they distribute cold air through a raised floor with perforated floor tiles or vents to direct the air into the room. At lower densities (1 to 5 kW/rack) adequate cooling is provided to sensitive IT equipment, despite the mixing of air throughout the room.
Representation and matching of articulated shapes (2004)

We consider the problem of localizing the articulated and deformable shape of a walking person in a single view. We represent the non-rigid 2D body contour by a Bayesian graphical model whose nodes correspond to point positions along the contour. The deformability of the model is constrained by learned priors corresponding to two basic mechanisms: local non-rigid deformation, and rotation motion of the joints. Four types of image cues are combined to relate the model configuration to the observed image, including edge gradient map, foreground/background mask, skin color mask, and appearance consistency constraints. The constructed Bayes network is sparse and chain-like, enabling efficient spatial inference through sequential Monte Carlo sampling methods. We evaluate the performance of the model on images taken in cluttered, outdoor scenes. The utility of each image cue is also empirically explored.

Molecular and Cellular Imaging with Targeted Contrast Ultrasound (2005)

Molecular imaging is an expanding field that involves the noninvasive detection of cellular and molecular mediators of disease using a range of imaging modalities. Molecular imaging using contrast-enhanced ultrasound relies on the detection of novel site-targeted ultrasound contrast agents. Gas-filled encapsulated microbubbles provide a sensitive and high-resolution ultrasound contrast agent, and site-targeted imaging is facilitated by the manipulation of the shell surface of these microbubbles. Nonmicrobubble agents such as immunoliposomes and small nanoemulsion agents have also been developed for targeting purposes. These contrast agents are retained within regions of a specific pathophysiological process, thereby allowing noninvasive phenotypic characterization of tissue. Since microbubbles are pure intravascular tracers, they provide an optimal agent to assess molecular processes occurring on the vascular endothelial surface. Accordingly, the pathologic states that have been targeted include inflammation, angiogenesis associated with ischemia and neoplasms, and thrombus formation. This review describes: 1) the potential clinical and research uses for targeted imaging; 2) strategies that have been employed for the creation of site-targeted ultrasound contrast agents; 3) the unique challenges for imaging targeted ultrasound contrast agents; and 4) initial results and experience in the imaging of molecular events in animal models of disease.
28 YEARS OF PRODUCTION AT CERRO PRIETO GEOTHERMAL FIELD (2000)

On the eve of celebrating the 30 th anniversary of starting electrical production from the Cerro Prieto Geothermal field a new stage of development is taking place by adding 100 MW to its 620 MW installed capacity. Although this field has been producing for almost 30 years, reservoir conditions such as pressure and temperature remain as high as 200 bar and 300°C in a large part of the reservoir. Cerro Prieto can thus be considered not only as the largest Mexican geothermal fields but as one of the oldest and most reliable geothermal systems in the world.
Efficacy of UV Treatment in the Management of Bacterial Adhesion on Hard Surfaces (2011)

The efficacy of UV treatment to control bacterial adhesion onto hard surfaces was investigated in laboratory conditions. The major characteristics necessary for biofilm formation like extracellular polymeric substance (EPS) production, carbohydrate and protein concentration in EPS, and adhesion ability onto hard surface were studied using two bacterial strains isolated from marine biofilms. The results showed that there was a considerable difference between the control and UV treated bacterial cultures in their viability, production of EPS, and adhesion ability. The protein and carbohydrate concentration of the EPS and the adhesion of bacterial cells to surface were also considerably reduced due to UV treatment. This study indicates that treatment of water with UV light may be used to control biofilm development on hard surfaces.
The Beginnings of Disengagement (1996)

Historically, strategic overstretch has generally only been recognized after the fact. An intentional overextension would tend to run counter to any notion of rational behavior. In almost every other case of strategic overstretch, it took a major war to force a state to reduce its commitments. In the case of the USSR, however, it wasn’t a global armed conflict but rather a change within the domestic political system that led the Soviet leadership to realize that they had overextended themselves in their Cold War against the United States.
