Scene boundary detection via video self-similarity analysis (2002)

We present a novel framework for analyzing video using self-similarity. Video scenes are located by analyzing inter-frame similarity matrices. The approach is flexible to the choice of similarity measure and is robust and data-independent because the data is used to model itself. We present the approach and its application to scene boundary detection. This is shown to dramatically outperform a conventional scene-boundary detector that uses a histogram-based measure of frame difference.
Magnetic Moments of Some Octahedral Complexes of Iridium (1954)

Magnetic susceptibilities of Na2IrCl6, Na3IrCl6·2H2O, and (NH4)2Ir(H2O)Cl5 were determined for these solids and for aqueous solutions 0.6f in the complex compound and 1f in HCl by the Gouy method. Na2IrCl6 is paramagnetic in the solid state and in solution, with a magnetic moment corresponding to one unpaired 5d electron and to d2sp3 covalent Ir–Cl bonds. The two iridium (III) complexes are diamagnetic, corresponding likewise to d2sp3 bond formation.

Deformable MR Prostate Segmentation via Deep Feature Learning and Sparse Patch Matching (2015)

Automatic and reliable segmentation of the prostate is an important but difficult task for various clinical applications such as prostate cancer radiotherapy. The main challenges for accurate MR prostate localization lie in two aspects: (1) inhomogeneous and inconsistent appearance around prostate boundary, and (2) the large shape variation across different patients. To tackle these two problems, we propose a new deformable MR prostate segmentation method by unifying deep feature learning with the sparse patch matching. First, instead of directly using handcrafted features, we propose to learn the latent feature representation from prostate MR images by the stacked sparse auto-encoder (SSAE). Since the deep learning algorithm learns the feature hierarchy from the data, the learned features are often more concise and effective than the handcrafted features in describing the underlying data. To improve the discriminability of learned features, we further refine the feature representation in a supervised fashion. Second, based on the learned features, a sparse patch matching method is proposed to infer a prostate likelihood map by transferring the prostate labels from multiple atlases to the new prostate MR image. Finally, a deformable segmentation is used to integrate a sparse shape model with the prostate likelihood map for achieving the final segmentation. The proposed method has been extensively evaluated on the dataset that contains 66 T2-wighted prostate MR images. Experimental results show that the deep-learned features are more effective than the handcrafted features in guiding MR prostate segmentation. Moreover, our method shows superior performance than other state-of-the-art segmentation methods.
Smart heating and air conditioning scheduling method incorporating customer convenience for home energy management system (2013)

A Home Energy Management System (HEMS) is expected to be vital for saving energy costs considering the time-varying price of electric power in a smart home environment. Studies on various energy resources such as energy storage systems and fuel cells in a smart home environment are required for HEMS development. In the area of the HEMSs, however, there exists very limited research on heating and air conditioning scheduling incorporating customer convenience. This paper presents a smart heating and air conditioning scheduling method for HEMS that considers customer convenience as well as characteristics of thermal appliances in a smart home environment. The prototype software based on the proposed method for HEMS is also implemented.
International Assessment of Research and Development in Brain-Computer Interfaces. WTEC Panel Report (2007)

Brain-computer interface (BCI) research deals with establishing communication pathways between the brain and external devices. BCI systems can be broadly classified depending on the placement of the electrodes used to detect and measure neurons firing in the brain: in invasive systems, electrodes are inserted directly into the cortex; in noninvasive systems, they are placed on the scalp and use electroencephalography or electrocorticography to detect neuron activity. This WTEC study was designed to gather information on worldwide status and trends in BCI research and to disseminate it to government decision makers and the research community. The study reviewed and assessed the state of the art in sensor technology, the biotic/abiotic interface and biocompatibility, data analysis and modeling, hardware implementation, systems engineering, functional electrical stimulation, noninvasive communication systems, and cognitive and emotional neuroprostheses in academic research and industry.
Aryl Diazonium <i>versus</i> Iodonium Salts: Preparation, Applications and Mechanisms for the Suzuki–Miyaura Cross‐Coupling Reaction (2011)

Abstract This review gives an overview of the use of unusual diazonium and iodonium salts as electrophiles for the Suzuki–Miyaura reaction. The discussion mainly focuses, with a critical view, on catalytic systems developed with these electrophiles. The review also discusses their general properties and preparation as well as mechanistic aspects. A last and brief comparison of diazonium versus iodonium salts, by highlighting advantages and drawbacks of both, gives the reader an understandable resumé.
Integrating logic and object-oriented programming (1991)

Method representation in most object-oriented programing languages is too procedural and less declarative and expressive. Logic programming with declarative semantics can contribute a lot to the expressiveness of representing methods. Therefore, it is very desirable to combine logic programming and object-oriented programming to get the advantages of both. LogiC++ that integrates logic and object-oriented programming is designed primarily based on C++. However, methods in a LogiC++ program can be represented by Prolog Horn clauses. In this paper, we describe a compiler that takes a LogiC++ program as input and produces an equivalent C++ program as the output. The C++ program can then be compiled by a C++ compiler.
A DNA Origami Nanorobot Controlled by Nucleic Acid Hybridization (2014)

A prototype for a DNA origami nanorobot is designed, produced, and tested. The cylindrical nanorobot (diameter of 14 nm and length of 48 nm) with a switchable flap, is able to respond to an external stimulus and reacts by a physical switch from a disarmed to an armed configuration able to deliver a cellular compatible message. In the tested design the robot weapon is a nucleic acid fully contained in the inner of the tube and linked to a single point of the internal face of the flap. Upon actuation the nanorobot moves the flap extracting the nucleic acid that assembles into a hemin/G-quadruplex horseradish peroxidase mimicking DNAzyme catalyzing a colorimetric reaction or chemiluminescence generation. The actuation switch is triggered by an external nucleic acid (target) that interacts with a complementary nucleic acid that is beard externally by the nanorobot (probe). Hybridization of probe and target produces a localized structural change that results in flap opening. The flap movement is studied on a two-dimensional prototype origami using Förster resonance energy transfer and is shown to be triggered by a variety of targets, including natural RNAs. The nanorobot has potential for in vivo biosensing and intelligent delivery of biological activators.

Strong Inference: rationale or inspiration? (2006)

John Platt's article "Strong Inference" (1964) suggested a general and effective method of scientific investigation. It describes a disciplined strategy of falsification of multiple, clearly formulated hypotheses that is used more regularly in some scientific fields than in others. Platt urged that strong inference be more widely and more systematically applied, particularly in slower-moving fields of science. The article has influenced integrative biological fields since its publication, ranging from ecology to psychology, and has had a substantial following in some of the social sciences. It has also evoked severe criticism for its idealization of certain fields as exemplars and for its imperfections in historiography and philosophy of science. I argue here that the article was more an inspirational tract than the development of a formal scientific methodology. Although both Platt's critics and his adherents appeared to take the article far too seriously, its influence has transcended its limitations.
Recurrent Network Model of the Neural Mechanism of Short-Term Active Memory (1991)

Two decades of single unit recording in monkeys performing short-term memory tasks has established that information can be stored as sustained neural activity. The mechanism of this information storage is unknown. The learning-based model described here demonstrates that a mechanism using only the dynamic activity in recurrent networks is sufficient to account for the observed phenomena. The temporal activity patterns of neurons in the model match those of real memory-associated neurons, while the model's gating properties and attractor dynamics provide explanations for puzzling aspects of the experimental data.

A Novel Meteorological Sensor Data Acquisition Approach Based on Unmanned Aerial Vehicle (2017)

Meteorological sensor data acquisition is critical for various applications and researches. Currently, meteorological sensor data monitoring and acquisition mainly relies on the automatic weather station (AWS), wireless sensor network, satellites, and airborne remote sensing, etc. However, these conventional methods have some insuperable deficiencies. Recent advances in the unmanned aerial vehicle (UAV) for scientific use make drones easily overcome some of the paucity generated by these means. UAV as a sensor bearing platform can be used to collect sensor data in a more responsive, timely, three dimensional, and cost-effective manners. By implementing sensor network alike methods, drones can simulate the mobile ad-hoc networks in a mission and reduce the communication energy cost between each sensor node. This paper first demonstrates the feasibility of this approach, then proposes a sensor bearing framework aiming to bridge UAV remote sensing technique and customised meteorological sensor. A system prototype is developed and some real-world field tests indicate the application of the proposed framework is practical.
Reentrant and nonreentrant mechanisms contribute to arrhythmogenesis during early myocardial ischemia: results using three-dimensional mapping. (1987)

The present study assessed the mechanisms responsible for the initiation and maintenance of premature ventricular complexes (PVCs) and ventricular tachycardia (VT) during early ischemia using a unique computerized mapping system capable of recording simultaneously from 232 individual intramural sites. In the chloralose-anesthetized cat, during normal sinus rhythm prior to ischemia, ventricular activation was rapid with a total activation time of 25 +/- 2 msec. Five minutes after occlusion of the left anterior descending (LAD) coronary artery, activation was delayed during sinus rhythm (64 +/- 6 msec) (p less than 0.001 vs. control) and was characterized by slow conduction in the same plane and block in both the same plane and in the endocardial-to-epicardial direction. In 76% of cases (16 of 21), initiation of single PVCs and the first beat of VT occurred through intramural reentry. In all but one case, initiation occurred in the subendocardium, adjacent to the site of delayed subendocardial and midmyocardial activation of the preceding sinus beat. The activation time of the sinus beat preceding the PVC or VT was significantly prolonged (149 +/- 7 msec, p less than 0.001 vs. sinus beats during ischemia not followed by a PVC or VT) with most of the delayed activity occurring in the subendocardium and midmyocardium, a finding that would not have been apparent by epicardial mapping alone. The length of the reentrant pathway ranged from 1.8-3.0 cm. Marked delay was a necessary, but not a sufficient, condition for reentry to occur since, in some cases, delays as large as 220 msec was found without initiation of reentry or the occurrence of nonreentrant PVCs or VT. Maintenance of VT by intramural reentry arose in either the subendocardium or the subepicardium and was primarily dependent on the continued presence of marked transmural delay (159 +/- 8 msec). In contrast, in 24% of cases (5 of 21), initiation of the first beat of VT arose in either the subendocardium or subepicardium by a mechanism other than reentry as evidenced by the lack of intervening electrical activity between the end of the preceding sinus beat and the initiation of the ectopic beat. The preceding sinus beat was characterized by delay (129 +/- 12 msec) comparable to that of sinus beats preceding reentrant ectopic beats (p = NS), but the marked delay was distant from the site of nonreentrant initiation. Ventricular tachycardia could be initiated by one mechanism (reentrant or nonreentrant) and maintained or terminated by another mechanism.(ABSTRACT TRUNCATED AT 400 WORDS)
PACTOS SOBRE SUCESIÓN FUTURA O SUCESIÓN CONTRACTUAL EN LA LEGISLACIÓN FRANCESA Y ESPAÑOLA ARAGONESA (2008)

Los pactos sobre la sucesion futura fueron reprobados por el Derecho Romano, pero durante los siglos XIV y siguientes gozaron de aceptacion en Europa, puesto que resultaban eficaces para vincular los bienes familiares a un solo heredero, conservando el patrimonio familiar intacto. El codigo civil frances, heredero de la Revolucion, los prohibio porque eran una amenaza a la igualdad que debia imperar entre los hijos en la reparticion de las herencias paterna y materna. Ademas se juzgo inmoral contratar sobre la sucesion eventual de alguien que aun vive. La influencia francesa quedo plasmada en los codigos que siguieron su ejemplo y la prohibicion se generalizo. Sin embargo, hoy en dia asistimos al proceso contrario, porque al discutirse la legalidad de las normas que imponen la igualdad de las legitimas, en circunstancias que los herederos pueden encontrarse en situaciones muy diversas, estos pactos, en especial los de renuncia a una eventual sucesion por parte de un heredero presuntivo, mayor de edad, resultan utiles para permitirle a un testador asignar con preferencia sus bienes a hijos incapacitados o a su conyuge. En 2006 fueron legalizados en el codigo civil frances.
A new ZCS-ZVS-PWM boost converter with unity power factor operation (2002)

This paper introduces the self-resonance concept as a new way to obtain power converters without switching losses. Using this new approach, a self-resonant ZCS-ZVS-PWM boost power converter is presented. It is suitable for high switching frequency, high power operation and wide range of power. The converter control is done by using PWM technique, with constant frequency operation. The complete theoretical analysis and simulation results for the self-resonant PWM boost power converter, operating without power factor correction, are presented. Moreover, experimental results for this new boost converter, operating with unity power factor, support the validity of this new approach. >
