Data Quality Assessment for Electrical Equipment Condition Monitoring (2022)

In recent years, with the rapid development of industrial informatization, the amount of data collected and to be processed in various fields is increasing day by day. In the era of big data, data is the carrier of information. During the process of data acquisition, dirty data may be generated due to factors such as personnel errors and equipment failures. Low-quality data can affect application reliability and lead to wrong decisions, therefore effective measures are required to be taken to guarantee data quality. Data quality assessment is an important part. At present, the quality assessment methods of some industrial data only stay in the theoretical framework, lack of concrete operating methods based on reality. In this paper, a data quality assessment system method is proposed for data of electrical equipment condition monitoring based on analytic hierarchy process. Specific rules will be designed according to data characteristics and internal connection to assess data quality from different dimensions such as integrity, accuracy, and uniqueness.
Comicolorization: Semi-Automatic Manga Colorization (2017)

We developed "Comicolorization", a semi-automatic colorization system for manga images. Given a monochrome manga and reference images as inputs, our system generates a plausible color version of the manga. This is the first work to address the colorization of an entire manga title (a set of manga pages). Our method colorizes a whole page (not a single panel) semi-automatically, with the same color for the same character across multiple panels. To colorize the target character by the color from the reference image, we extract a color feature from the reference and feed it to the colorization network to help the colorization. Our approach employs adversarial loss to encourage the effect of the color features. Optionally, our tool allows users to revise the colorization result interactively. By feeding the color features to our deep colorization network, we accomplish colorization of the entire manga using the desired colors for each panel.
Collective versus local measurements on two parallel or antiparallel spins (2000)

We give a complete analysis of covariant measurements on two spins. We consider the cases of two parallel and two antiparallel spins, and we consider both collective measurements on the two spins and measurements that require only local quantum operations and classical communication (LOCC). In all cases we obtain the optimal measurements for arbitrary fidelities. In particular, we show that if the aim is to determine as accurately as possible the direction in which the spins are pointing, it is best to carry out measurements on antiparallel spins (as already shown by Gisin and Popescu), second best to carry out measurements on parallel spins, and worst to be restricted to LOCC measurements. If the aim is to determine as accurately as possible a direction orthogonal to that in which the spins are pointing, it is best to carry out measurements on parallel spins, whereas measurements on antiparallel spins and LOCC measurements are both less suitable but equivalent.
Phase Behavior of a Poly(ethylene oxide)-block- Poly(isoprene) Copolymer in Aqueous Solutions: From Liquid to Solid State (2002)

The phase behavior and structures of a poly(ethylene oxide-block-isoprene) diblock, having a volume fraction of poly(ethylene oxide), fPEO, of 0.64, have been determined as a function of polymer concentration in water, and of temperature between 5 and 80 °C, using rheology and small/wide-angle X-ray scattering. Sol−gel boundaries were established by rheometry whereas small-angle X-ray scattering was employed to identify the lyotropic phases. For concentrations of diblock below 15 wt %, a liquid-like structure is obtained. Above 25 wt % copolymer in water, a lamellar morphology is observed which exhibits, for the pure sample, an order−disorder transition at 190 °C. Between these two concentrations a face-centered cubic (fcc) structure is adopted. As the concentration of copolymer is increased in the fcc regime, the size of the spheres increases before to transform directly into a lamellar morphology.
Cloud in a cloud for cloud education (2012)

The proper education of engineers will be crucial for the continued development of cloud technologies. We have developed a cloud called edubase Cloud for information technology education. In this paper, we discuss how edubase Cloud supports cloud educational materials through a case study and how effective it is for educating cloud engineers.
Some experiments at high supersonic speeds on the aerodynamic and boundary-layer transition characteristics of high-drag bodies of revolution (1957)

Report presenting measurements made at Mach numbers of 4.0 and 8.3 of the drag, static stability, damping in pitch, and boundary-layer transition characteristics of several high-drag bodies of revolution that might be used for high-speed entry into the earth's atmosphere. The static stability was found to be high with centers of pressure as far aft as 91 percent of the length from the nose. Results regarding the force and moment data, boundary-layer transition, a comparison of roughness height to boundary-layer thickness, other causes of boundary-layer instability, and Reynolds numbers for high-speed entry into the Earth's atmosphere are provided.
Low optical insertion-loss and vacuum-pressure all-fiber acetylene cell based on hollow-core photonic crystal fiber (2006)

We report a novel and easy-to-implement hollow-core photonic crystal fiber cell fabrication technique based on helium diffusion through silica. The formed gas cells combine low optical insertion loss (1.8 dB) and vacuum acetylene pressure (microbar regime). The estimates of the final gas pressure, using both Voigt interpolation and electromagnetically induced transparency, show a good match with the initial fitting pressure.
Development and Evaluation of a Car Navigation System Providing a Bird's-Eye View Map Display (1996)

&lt;div class="htmlview paragraph"&gt;A new map display technique has been developed for car navigation systems that presents a bird's-eye view of three-dimensional map images. This view allows both detailed and wide-area information to be presented simultaneously in a single screen display. It provides drivers with a reassuring feeling while driving along their route because the two types of information can guide them accurately to their destination. The results of evaluation tests have confirmed the effectiveness of this technique. On the other hand, some aspects requiring further improvement were also identified. This paper discusses how the technique was developed and describes the tests conducted to evaluate its effectiveness along with the results obtained.&lt;/div&gt;

Kinematics of the Beating Heart (1980)

We introduce a new approach to the quantification of myocardial strain. It utilizes the theoretical frame work of kinematics and can thus account for the large time-varying displacements present in the intact beating heart. For arbitrary small segments of myocardium, we show how these displacements can be described completely by a rotation tensor and a stretch tensor. We demonstrate the physiologic meaning of this analysis in an anesthetized dog. An epicardial region was seen to exhibit a local twist quantified by the rotation tensor and a segmental shortening quantified by the stretch tensor.
[Biochemical characterization of an immune serum which specifically marks neurons in neurofibrillary degeneration in Alzheimer's disease]. (1986)

We have raised an antiserum which is labelling specifically neurofibrillary tangles of Alzheimer's disease. We show here that anti-tangles detects on immunoblots exclusively Tau, a set of proteins that promote microtubule assembly. Conversely, an anti Tau detects histologically Alzheimer tangles. Accordingly, neurofibrillary tangles are very likely composed of aggregated Tau proteins, due to an anomaly of microtubular protein synthesis or to a general suffering of certain pyramidal neurons leading to an elective aggregation of Tau.
DisCoverage: A new paradigm for multi-robot exploration (2010)

The main aspect in multi-robot exploration is the efficient coordination of a group of robots. Inspired by previous results on the coverage problem, we propose a novel, frontier-based approach for multi-robot exploration. This approach merges the step of choosing appropriate target points with the step of planning a collision-free path. This is achieved by optimizing an objective function consisting of distance and orientation costs as well as an estimated information gain. The optimization yields motion control laws directly solving the exploration task. Using a Voronoi partition of the environment ensures, that each robot autonomously creates and optimizes the objective function to obtain a collision-free path in a distributed fashion. Simulations demonstrate the effectiveness of our approach.
Munc18-1 Tuning of Vesicle Merger and Fusion Pore Properties (2011)

The release of hormones and neurotransmitters, mediated by regulated exocytosis, can be modified by regulation of the fusion pore. The fusion pore is considered stable and narrow initially, eventually leading to the complete merger of the vesicle and the plasma membranes. By using the high-resolution patch-clamp capacitance technique, we studied single vesicles and asked whether the Sec1/Munc18 proteins, interacting with the membrane fusion-mediating SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins, affect fusion pore properties. Munc18-1 mutants were transfected into lactotrophs to affect the interaction of Munc18-1 with syntaxin1 (Synt1) (R39C), Rab3A (E466K), and Mints (P242S). Compared with wild-type, Munc18-1 E466K increased the frequency of the fusion event. The latter two mutants increased the fusion pore dwell-time. All the mutants stabilized narrow fusion pores and increased the amplitude of fusion events, likely via preferential fusion of larger vesicles, since overexpression of Munc18-1 R39C did not affect the average size of vesicles, as determined by stimulated emission depletion (STED) microscopy. Single-molecule atomic force microscopy experiments revealed that wild-type Munc18-1, but not Munc18-1 R39C, abrogates the interaction between synaptobrevin2 (Syb2) and Synt1 binary trans-complexes. However, neither form of Munc18-1 affected the interaction of Syb2 with the preformed binary cis-Synt1A-SNAP25B complexes. This indicates that Munc18-1 performs a proofing function by inhibiting tethering of Syb2-containing vesicles solely to Synt1 at the plasmalemma and favoring vesicular tethering to the preformed binary cis-complex of Synt1A-SNAP25B. The association of Munc18-1 with the ternary SNARE complex leads to tuning of fusion pores via multiple and converging mechanisms involving Munc18-1 interactions with Synt1A, Rab3A, and Mints.
Subnormothermic Preservation in Somah: A Novel Approach for Enhanced Functional Resuscitation of Donor Hearts for Transplant (2014)

Organ preservation at 4°C results in temporally irreversible injury to cellular structure and function. This study was designed to evaluate the possibility of storing hearts at ambient temperatures in novel organ preservation solution Somah to prevent damage and preserve optimum function by maintaining cellular energy over the temperature range of storage. Porcine hearts were stored in Celsior at 4°C and Somah at 4°C, 13°C and 21°C for 5 h thereafter reperfused and reanimated in vitro for 3 h. Heart weights, histopathology, ultrastructure and 2-dimensional echocardiography (2D-Echo) assessments showed preservation of structure in Somah groups. Tissue high-energy phosphate levels in Somah groups after storage were significantly greater than the Celsior hearts (p < 0.05) and highest in the 21°C Somah hearts. Upon reperfusion, myocardial O2 consumption and lactate levels quickly achieved steady state in 21°C hearts, but were delayed in Somah 4/13°C groups and severely depressed in the Celsior group. Inotrope and electroconversion requirements were inversely related to storage temperature. In vitro 2D Echo demonstrated a discordantly attenuated function in the Celsior group, moderate functionality in 4°C Somah group and superior reestablishment of performance in the Somah higher temperature groups. Hearts stored in Somah at 21°C were metabolically and functionally superior to any other groups.
High-Voltage-Tolerant I/O Circuit Design for USB 2.0-Compliant Applications (2007)

We present design strategies of high-voltage tolerant I/O circuits for interfaces of 3.3 V or higher. The test vehicle is a USB 2.0-compliant I/O circuit. This is a challenging example because USB 2.0 requires substantial over-voltage tolerance from -IV to 5.25 V. In addition, USB 2.0 requires continuous monitoring of this condition and protection when no power is present. The proposed concept is demonstrated in a 90 nm CMOS process.
Electrochemical Impedance Spectroscopy Study into the Effect of Titanium Dioxide Added to the Alkaline Manganese Dioxide Cathode (2011)

A combination of step potential electrochemical spectroscopy (SPECS) and electrochemical impedance spectroscopy (EIS) has been used to examine the effect of anatase titanium dioxide added to the alkaline manganese dioxide electrode. The inclusion of titanium dioxide was found to improve performance by lowering the resistance to charge transfer at the MnO2/electrolyte/graphite interface. Furthermore, a consideration of mass transport processes within the electrode indicates that titanium ions may become incorporated into the γ-MnO2 lattice upon cycling, impacting H+/e− mass transport.
Identifying Opportunities for Byte-Addressable Non-Volatile Memory in Extreme-Scale Scientific Applications (2012)

Future exascale systems face extreme power challenges. To improve power efficiency of future HPC systems, non-volatile memory (NVRAM) technologies are being investigated as potential alternatives to existing memories technologies. NVRAMs use extremely low power when in standby mode, and have other performance and scaling benefits. Although previous work has explored the integration of NVRAM into various architecture and system levels, an open question remains: do specific memory workload characteristics of scientific applications map well onto NVRAMs' features when used in a hybrid NVRAM-DRAM memory system? Furthermore, are there common classes of data structures used by scientific applications that should be frequently placed into NVRAM?In this paper, we analyze several mission-critical scientific applications in order to answer these questions. Specifically, we develop a binary instrumentation tool to statistically report memory access patterns in stack, heap, and global data. We carry out hardware simulation to study the impact of NVRAM for both memory power and system performance. Our study identifies many opportunities for using NVRAM for scientific applications. In two of our applications, 31% and 27% of the memory working sets are suitable for NVRAM. Our simulations suggest at least 27% possible power savings and reveal that the performance of some applications is insensitive to relatively long NVRAM write-access latencies.

[Two cases of colonic diverticular bleeding in which the combination of a planned marking clip and dynamic computed tomography was useful for identification of the bleeding site]. (2014)

We experienced two cases of shock secondary to colonic diverticular bleeding. Both patients showed signs of shock after each episode of melena; however, the bleeding site could not be initially identified because multiple diverticula were present and the bleeding spontaneously ceased during each examination. Therefore, we subsequently performed planned clipping and dynamic computed tomography scanning of the area surrounding the potential bleeding sites to look for signs of vascular leakage and to determine the clip location. The use of this method enabled us to successfully identify the bleeding site in both cases. Thus, this method can be useful in identifying the site of colonic diverticular bleeding that may cause shock.
Wireless erasure networks with feedback (2008)

Consider a lossy packet network of queues, communicating over a wireless medium. This paper presents a throughput-optimal transmission strategy for a unicast network when feedback is available, which has the following advantages: It requires a very limited form of acknowledgment feedback. It is completely distributed, and independent of the network topology. Finally, communication at the information theoretic cut-set rate requires no network coding and no rateless coding on the packets. This simple strategy consists of each node randomly choosing a packet from its buffer to transmit at each opportunity. However, the packet is only deleted from a nodepsilas buffer once it has been successfully received by the final destination.
SEPARATION AND DETERMINATION OF ALKYLFURYLSILANE ISOMERS FOR HPLC (2010)

In this paper are presented optimal conditions of chromatographic separation of two isomers: γ-(chloropropyl)-3-furyldimethylsilane and [2-chloro(1-methyl)ethyl](3′-furyl)dimethylsilane. These isomers show the ability of modification of the surface of silica gel. In the investigation were tested three stationary phases and three mobile phases: dichloromethane, methanol, and a mixture of dichloromethane and hexane (80/20, v/v), in different flow intensities. An application of octadecyl stationary phase, which is recommended as a standard phase, did not yield separation of the isomers, independently of composition and flow of a mobile phase. Better results, but with asymmetric peaks have been obtained on the octyl phase. Finally, aryl chemically bonded phases permitted acquiring good separation of the isomers in a time shorter than 25 min. The best separation factor (1.11) has been obtained on the chemically bonded aryl phase using dichloromethane with flow of 0.1 mL · min−1. Therefore, the best selectivity in separation of above mentioned compounds exhibited the aryl chemically bonded phase.
Assessing the implementation of user-centred design standards on assistive technology for persons with visual impairments: A systematic review (2023)

Abstract Despite scientific and technological advances in the field of assistive technology (AT) for people with visual impairment (VI), technological designs are frequently based on a poor understanding of the physical and social context of use, resulting in devices that are less than optimal for their intended beneficiaries. To resolve this situation, user-centred approaches in the development process of AT have been widely adopted in recent years. However, there is a lack of systematization on the application of this approach. This systematic review registered in PROSPERO (CRD42022307466), assesses the application of the ISO 9241-210 human-centred design principles in allegedly “user-centred designed” AT developments for persons with VI (see S1 PROSPERO Protocol). The results point to a wide variation of the depth of understanding of user needs, a poor characterization of the application of the User Centred Design (UCD) approach in the initial design phases or in the early prototyping, and a vague description of user feedback and device iteration. Among the principles set out in ISO 9241-210, the application of 5.6: “the design team includes multidisciplinary skills and perspectives” is the one for which the least evidence is found. The results show there is not enough evidence to fully assess the impact of UCD in 1. promoting innovation regarding AT products and practices, and 2. Judging if AT produced following such standards is leading to better user access, wellbeing outcomes and satisfaction. To address this gap it is necessary to, first, generate better implementation of UCD in AT development and second, to strengthen evidence regarding the implementation and outcomes of using UCD for AT. To better engage with the realities of persons with VI, we propose capacity building across development teams regarding UCD, its principles and components; better planning for UCD implementation; and cross-fertilization across engineering disciplines and social and clinical science.

3D tomography of cells in micro-channels (2017)

We combine confocal imaging, microfluidics and image analysis to record 3D-images of cells in flow. This enables us to recover the full 3D representation of several hundred living cells per minute. Whereas 3D confocal imaging has thus far been limited to steady specimen, we overcome this restriction and present a method to access the 3D shape of moving objects. The key of our principle is a tilted arrangement of the micro-channel with respect to the focal plane of the microscope. This forces cells to traverse the focal plane in an inclined manner. As a consequence, individual layers of passing cells are recorded which can then be assembled to obtain the volumetric representation. The full 3D information allows for a detailed comparisons with theoretical and numerical predictions unfeasible with e.g.\ 2D imaging. Our technique is exemplified by studying flowing red blood cells in a micro-channel reflecting the conditions prevailing in the microvasculature. We observe two very different types of shapes: `croissants' and `slippers'. Additionally, we perform 3D numerical simulations of our experiment to confirm the observations. Since 3D confocal imaging of cells in flow has not yet been realized, we see high potential in the field of flow cytometry where cell classification thus far mostly relies on 1D scattering and fluorescence signals.
Phase II Trial of Pemetrexed and Bevacizumab in Patients With Recurrent or Metastatic Head and Neck Cancer (2011)

The addition of bevacizumab to pemetrexed resulted in promising efficacy outcomes in SCCHN. Bleeding events were frequent but some may have been due to natural history of disease. Polymorphisms in MTHFR may offer potential for treatment individualization.
Conformationally constrained nucleoside phosphonic acids – potent inhibitors of human mitochondrial and cytosolic 5′(3′)-nucleotidases (2014)

This work describes novel in vitro inhibitors of human mitochondrial (mdN) and cytosolic (cdN) 5'(3')-deoxynucleotidases. We designed a series of derivatives of the lead compound (S)-1-[2-deoxy-3,5-O-(phosphonobenzylidene)-β-d-threo-pentofuranosyl]thymine bearing various substituents in the para position of the benzylidene moiety. Detailed kinetic study revealed that certain para substituents increase the inhibitory potency (iodo derivative; K = 2.71 μM) and some induce a shift in selectivity toward cdN (carboxy derivative, K = 11.60 μM; iodoxy derivative, K = 6.60 μM). Crystal structures of mdN in complex with three of these compounds revealed that various para substituents lead to two alternative inhibitor binding modes within the enzyme active site. Two binding modes were also identified for cdN complexes by heteronuclear NMR spectroscopy.
