A new look at spotlight mode synthetic aperture radar as tomography: imaging 3-D targets (1995)

A new 3D tomographic formulation of spotlight mode synthetic aperture radar (SAR) is developed. This extends the pioneering work of Munson et al. (1983), who first formally described SAR in terms of tomography but who made the simplifying assumption that the target scene was 2D. The present authors treat the more general and practical case in which the radar target reflectivities comprise a 3D function. The main goal is to demonstrate that the demodulated radar return data from a spotlight mode collection represent a certain set of samples of the 3D Fourier transform of the target reflectivity function and to do so using a tomographic paradigm instead of traditional range-Doppler analysis. They also show that the tomographic approach is useful in interpreting the reconstructed 2D SAR image corresponding to a 3D scene. Specifically, the well-known SAR phenomenon of layover is easily explained in terms of tomographic projections and is shown to be analogous to the projection effect in conventional optical imaging.

Formal and use-case driven requirement analysis in UML (2002)

We have recently proposed a formalization of the use of UML in requirement analysis. This paper applies that formalization to a library system as a case study. We intend to show how the approach supports a use case-driven, step-wised and incremental development in building models for requirement analysis. The actual process of building the models shows the importance and feasibility of the formalization itself.
Sampling Argentine stem weevil, <i>Listronotus bonariensis</i> (Kuschel), populations in pasture: The soil‐dwelling stages (1989)

Abstract Previously described sampling systems for the soil‐dwelling stages of the Argentine stem weevil, Listronotus bonariensis (Kuschel), are briefly reviewed. Sampling and extraction techniques developed and extensively tested by the authors are described. A manually operated 75 mm diam. soil corer was used for field sampling. A mechanical method was used for the rapid and large‐scale extraction of adult, pupal. and prepupal stages from soil cores. The method gives acceptable recovery rates for all these stages. Taylor's powerlaw analysis was performed on sample mean and variance estimates of adult and prepupal plus pupal stages, and used to develop numerical sampling equations. A sampling plan is described for sampling populations to attain specific levels of precision at different population densities.
Audio fingerprinting to identify multiple videos of an event (2010)

The proliferation of consumer recording devices and video sharing websites makes the possibility of having access to multiple recordings of the same occurrence increasingly likely. These co-synchronous recordings can be identified via their audio tracks, despite local noise and channel variations. We explore a robust fingerprinting strategy to do this. Matching pursuit is used to obtain a sparse set of the most prominent elements in a video soundtrack. Pairs of these elements are hashed and stored, to be efficiently compared with one another. This fingerprinting is tested on a corpus of over 700 YouTube videos related to the 2009 U.S. presidential inauguration. Reliable matching of identical events in different recordings is demonstrated, even under difficult conditions.

Synthesis of [99mTc]ethyjenedicysteine-colchicine for evaluation of antiangiogenic effect (1999)

Angiogenesis is in part responsible for tumor growth and the development of metastasis. Radiolabeled angiongenesis inhibitors would be useful to assess tumor microvasculature density. Colchicine (COL), a potent antiangiogenic agent, is known to inhibit microtubule polymerization and cell arrest at metaphase. This study aimed to develop 99mTc-labeled COL (EC-COL) using ethylenedicysteine (EC) as a chelator to assess tumor microvascular density. EC was conjugated to trimethylcolchicinic acid using N-hydroxysuccinimide and 1-ethyl-3-dimethylaminopropyl carbodiimide as coupling agents with a yield of 50-60%. In vivo stability was analyzed in rabbit serum at 0.5-4 h. Tissue distribution and planar imaging studies of [99mTc]EC-COL were evaluated in breast tumor-bearing rats at 0.5, 2 and 4 h. The data was compared to that using [99mTc]EC (control). The radiochemical yield of [99mTc]EC-COL was greater than 95%. [99mTc]EC-COL was stable in rabbit serum. In vivo biodistribution of [99mTc]EC-COL in breast tumor-bearing rats showed increased tumor-to-blood (0.52+/-0.12 to 0.72+/-0.07) and tumor-to-muscle (3.47+/-0.40 to 7.97+/-0.93) ratios as a function of time. Conversely, tumor-to-blood values showed a time-dependent decrease with [99mTc]EC over the same time period. Planar images confirmed that the tumors could be visualized clearly with [99mTc]EC-COL from 0.5 to 4 h. [99mTc]EC-COL may be useful to assess antiangiogenic and therapeutic effects during chemotherapy.
Clock Technology: The Next Frontier (2017)

Clocking of electrical circuit is a crucial issue since clock signal is used to establish the flow-of-time inside electronic world. Before, during and after the "Moore's law", flow-of-time is an eternal issue. Alongside processor, memory/storage and analog/ RF technologies, IC clocking could be regarded as the 4th major IC design technology. In the past several decades, clock is mostly used in the form of fixed-frequency with high frequency stability. For future system, however, this type of clock signal is not sufficient because its usage environment is not expected to be stationary but dynamic. To meet this challenge, innovation in IC clocking is required. This paper first discusses the difficulties in creating flow-of-time; then the two long-lasting problems in clock generation are identified, and then new challenges in the design of future system are summarized. Afterwards, the Time-Average-Frequency based flexible clock generator is introduced and its potential to confront these challenges is addressed. Several major issues in modern design are discussed. The paper concludes with a vision that, for electronic system to improve its information processing efficiency to next level, clock technology is the next frontier to be explored.

Imaging calcium signals <i>in vivo</i>: a powerful tool in physiology and pharmacology (2010)

The design and engineering of organic fluorescent Ca(2+) indicators approximately 30 years ago opened the door for imaging cellular Ca(2+) signals with a high degree of temporal and spatial resolution. Over this time, Ca(2+) imaging has revolutionized our approaches for tissue-level spatiotemporal analysis of functional organization and has matured into a powerful tool for in situ imaging of cellular activity in the living animal. In vivo Ca(2+) imaging with temporal resolution at the millisecond range and spatial resolution at micrometer range has been achieved through novel designs of Ca(2+) sensors, development of modern microscopes and powerful imaging techniques such as two-photon microscopy. Imaging Ca(2+) signals in ensembles of cells within tissue in 3D allows for analysis of integrated cellular function, which, in the case of the brain, enables recording activity patterns in local circuits. The recent development of miniaturized compact, fibre-optic-based, mechanically flexible microendoscopes capable of two-photon microscopy opens the door for imaging activity in awake, behaving animals. This development is poised to open a new chapter in physiological experiments and for pharmacological approaches in the development of novel therapies.
Communication Using Antennas Fabricated in Silicon Integrated Circuits (2007)

The feasibility of integrating compact antennas and required circuits for implementing wireless interconnections in foundry digital CMOS technologies has been demonstrated. A 3-mm long zigzag dipole antenna on a 20-Omega-cm substrate should have efficiency up to approximately 25% at 24 GHz and cost 1-2 cents. These antennas can be used to implement a radio for 100-kb/s communication up to about 10 m. By lowering the operation frequency to 5.8 GHz and using a monopole structure, which occupies approximately 30% more area, the communication range can be increased by three times or more. This technology, as well as in a true single-chip radio, can be used for intra- and inter-chip data communication, intra- and inter-chip clock distribution, beacons, radars, RFID tags, and contactless high-frequency testing.
Novel deletions of 14q11.2 associated with developmental delay, cognitive impairment and similar minor anomalies in three children (2007)

The minimal common deletion region on chromosome 14q11.2 is only approximately 35 kb (from 20.897 to 20.932, University of California at Santa Cruz (UCSC) Genome Browser; build hg18, March 2006) and includes only two genes, SUPT16H and CHD8, which are good candidate genes for the phenotypes. The non-recurrent breakpoints of these patients, the presence of normal copy number variants in the region and the local genomic structure support the notion that this region has reduced stability.
Angle Estimation With Polarization Filtering: A Single Snapshot Approach (2017)

When a monopulse radar is subjected to main-lobe barrage interference, the target and the interference source are both located within the 3 dB beamwidth of the radar; the target returns are subsumed by the interference, which results in incorrect detection, erroneous angle measurements, and tracking error. Based on a hybrid polarimetric monopulse radar with six channels, a new approach is presented for estimating the target angle from a single snapshot in the presence of main-lobe barrage interference. By means of polarization filtering and polarization synthesis of signals from multiple channels with two orthogonal polarizations, a new pair of sum and difference signals is formed that represents the angle difference between the target and the interference source. After standard monopulse processing of these new signals and additional compensation, the estimate of the target angle is derived with low computational complexity.
Reconstruction of a high resolution image from registration and restoration of low resolution images (2002)

In applications that demand highly detailed images, it is often not feasible nor sometimes possible to acquire images of such high resolution by just using hardware (high precision optics and charge coupled devices (CCDs)). Instead, image processing methods may be used to construct a high resolution image from multiple, degraded, low resolution images. It is assumed that the low resolution images have been sub-sampled and displaced by sub-pixel shifts. Therefore, the problem can be divided into three sub-problems: registration (estimating the shifts), restoration, and interpolation. This paper focuses on solving the first two sub-problems simultaneously, using the expectation-maximization (EM) algorithm. Experimental results are presented that demonstrate the effectiveness of this approach.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A 10-bit DAC with 2.9 μν low frequency noise for high performance MEMS capacitive accelerometer application (2015)

A high performance microelectromeachical systems(MEMS) capacitive accelerometer in seismic detection system requires a low noise programmable analog signal for gravitational acceleration cancellation. This paper presents a monotone 10-bit digital-to-analog converter (DAC) for this application. The proposed DAC which generates a low noise analog signal is used to cancel out gravitational acceleration during the accelerometer operating. The DAC was fabricated on a 0.5 um triple-well CMOS process. The measured 0.1 Hz to 10 Hz noise is about 2.9 uV.
Workload Prediction for Cloud Cluster Using a Recurrent Neural Network (2016)

Maximizing benefits from a cloud cluster with minimum computational costs is challenging. An accurate prediction to cloud workload is important to maximize resources usage in the cloud environment. In this paper, we propose an approach using recurrent neural networks (RNN) to realize workload prediction, where CPU and RAM metrics are used to evaluate the performance of the proposed approach. In order to obtain optimized parameter set, an orthogonal experimental design is conducted to find the most influential parameters in RNN. The experiments with Google Cloud Trace data set shows that the RNN based approach can achieve high accuracy of workload prediction, which lays a good foundation for optimizing the running of a cloud computing environment.
Design, Synthesis, and Initial Evaluation of High-Affinity Technetium Bombesin Analogues (1998)

Potent antagonists of bombesin-like peptides have shown great potential for applications in cancer therapy. A 99mTc-labeled agent capable of identifying patients who could benefit from these emerging therapies would have a great impact on patient management. This study involves the synthesis and initial evaluation of technetium diaminedithiolate analogues derived from the potent bombesin analogue Pyr-Gln-Lys-Leu-Gly-Asn-Gln-Trp-Ala-Val-Gly-His-Leu-Met-NH2 (Lys3-bombesin). We coupled two diaminedithiol (DADT) bifunctional chelating agents (BCAs 1 and 2) to the Lys3 residue at the N-terminal region that is not required for binding to the receptor. 99mTc labeling was performed by ligand exchange on addition of [99mTc]glucoheptonate to a solution of the adduct at room temperature. Two products were obtained from each adduct on analysis by HPLC. The major to minor product ratios of the 99mTc-labeled analogues were 3:1 for products from BCA 1 and 9:1 for the products from BCA 2. Macroscopic amounts of the 99Tc analogues were similarly prepared using [99Tc]glucoheptonate. In this case, the major to minor ratios were 2:1 for the products from both BCAs. For initial evaluation of the binding of the Tc-labeled peptides to bombesin receptors, the 99Tc analogues were used in vitro in competitive binding assays in rat brain cortex membranes against [125I-Tyr4]bombesin. Results of the in vitro assays showed that the inhibition constants (Ki) of the major and minor products were 3.5+/-0.7 and 3.9+/-1.5 nM, respectively, for the products from BCA 1; and 7.4+/-2.0 and 5.2+/-1.5 nM for the products derived from BCA 2, respectively. The high affinity exhibited by these technetium analogues is an indication of their potential for use in non-invasive in vivo biochemical characterization of cancers that possess receptors for bombesin.
Combined acoustic and pronunciation modelling for non-native speech recognition (2007)

In this paper, we present several adaptation methods for non-native speech recognition. We have tested pronunciation modelling, MLLR and MAP non-native pronunciation adaptation and HMM models retraining on the HIWIRE foreign accented English speech database. The ``phonetic confusion'' scheme we have developed consists in associating to each spoken phone several sequences of confused phones. In our experiments, we have used different combinations of acoustic models representing the canonical and the foreign pronunciations: spoken and native models, models adapted to the non-native accent with MAP and MLLR. The joint use of pronunciation modelling and acoustic adaptation led to further improvements in recognition accuracy. The best combination of the above mentioned techniques resulted in a relative word error reduction ranging from 46% to 71%.

Autonomously Contracting Human Cardiomyocytes Generated from Adult Pancreatic Stem Cells and Enhanced in Co-Cultures with Myocardial Biopsies (2006)

Myocardial regeneration with artificially applied cardiomyocytes is emerging as a promising issue of significant scientific and clinical impact. Nevertheless the source of cells for human cardiomyocyte differentiation especially from adult tissue is still unclear. We hypothesized that human pancreatic stem cells may differentiate into cardiomyocyte-like cells and may increase in number when co-cultured with myocardial tissue. Adult stem cells were harvested from pancreatic tissue of patients undergoing operative procedures including the pancreas. The cells were selected, cultured and passaged. To promote self-differentiation into cardiomyocytes, human pancreatic stem cells were co-cultered with biopsies of human myocardium. After co-culture and breeding, cells were phenotyped as well with respect to RNA, protein and cardiomyocyte specificity at the electron-microscopic level.Pancreatic stem cells have already differentiated spontaneously into cardiomyocyte-like cells performing netlike cell clusters with rare but distinct multilocular cellular autonomous contractions with a frequency of about 20 beats per minute. The number of contracting areas however could be enhanced by co-culture with human myocardial biopsies. On RNA and protein levels as well as in electron-microscopy, evidence for cardiomyocyte specificity is shown. To the best of our knowledge this is the first report demonstrating the feasibility of generating autonomously contracting cardiomyocyte-like cells from adult human pancreatic stem cells and their enhancement by myocardial co-culture. This procedure might prove to be an alternative source and method for myocardial regenerative medicine.
Role of Pulmonary Macrophages in Resistance to Experimental Metastasis (1986)

Intranasal inoculation of C3H/HeN mice with Propionibacterium acnes activates pulmonary macrophages but not splenic or peritoneal macrophages. When mice so treated were injected IV with tumor cells, no protection against the challenge was seen. Conversely, inoculation of C3H/HeN mice with P. acnes by the IP route activated splenic and peritoneal macrophages but not pulmonary macrophages. When mice with activated splenic and peritoneal macrophages were challenged with an IV injection of tumor cells, the mice demonstrated an increased resistance to the formation of pulmonary tumors. Thus, activation of splenic and peritoneal macrophages correlated better with protection against IV tumor challenge than activation of pulmonary macrophages. Experiments were done that demonstrated that the effect was not due to the augmentation of NK cell activity. The data are consistent with the conclusion that activated pulmonary macrophages alone are not effective in conferring resistance to pulmonary tumor nodule formation in this tumor model.
Water adsorption on activated carbons with different degrees of oxidation (1997)

A typical activated carbon, derived from olive stones, has been oxidized to different degrees with (NH 4 ) 2 S 2 O 8 and analysed by water vapour adsorption, immersion calorimetry, acid–base titration and temperature-programmed desorption of CO 2 and CO monitored by mass spectrometry. These techniques led to a coherent description of the surfaces and of their chemistry. The water adsorption isotherms, of type IV, were decomposed into type I and V contributions and analysed in terms of the Dubinin–Astakhov equation. The corresponding calculated enthalpies of immersion into water are in agreement with the experimental values. The number of carboxyl, lactone, phenol and basic groups identified by titration, can also be related to the parameters of the Dubinin–Astakhov equation and to the enthalpy of immersion into water. Finally, a good linear correlation is found between the amounts of CO 2 and CO desorbed from the surface, the enthalpies of immersion into water and the total number of sites identified on the surface.
FEPDS: A Proposal for the Extraction of Fuzzy Emerging Patterns in Data Streams (2020)

Nowadays, most data is generated by devices that produce data continuously. These kinds of data can be categorized as data streams and valuable insights can be extracted from them. In particular, the insights extracted by emerging patterns (EPs) are interesting in a data stream context as easy, fast, and reliable decisions can be made. However, their extraction is a challenge due to the necessary response time, memory, and continuous model updates. In this article, an approach for the extraction of EPs in data streams is presented. It processes the instances by means of batches following an adaptive approach. The learning algorithm is an evolutionary fuzzy system where previous knowledge is employed in order to adapt to concept drift. A wide experimental study has been performed in order to show both the suitability of the approach in combating concept drift and the quality of the knowledge extracted. Finally, the proposal is applied to a case study related to the continuous determination of the profiles of New York City cab customers according to their fare amount, in order to show its potential.
Marsilea quadrifolia L. (klaverbladvaren) nieuw voor Nederland (1999)

In 1998 Marsilea quadrifolia was observed for the first time in the Netherlands, on the bank of a sheet of water in a foreland of the river Waal, 190 km north of its nearest (former) localities, in a pioneer vegetation belonging to the association Eleocharito acicularis-Limoselletum, resembling its past occurrence in similar plant communities in Hungarian rice fields and in the Upper Rhine Valley. Two of the three specimens produced 20 sporocarps altogether. The new appearance of a European Red List species in the Dutch riverine area might be termed a striking and encouraging phenomenon which was made possible by a new kind of water and nature management.
Nanoscale magnetic sensing using spin qubits in diamond (2008)

The ability to sense nanotelsa magnetic fields with nanoscale spatial resolution is an outstanding technical challenge relevant to the physical and biological sciences. For example, detection of such weak localized fields will enable sensing of magnetic resonance signals from individual electron or nuclear spins in complex biological molecules and the readout of classical or quantum bits of information encoded in an electron or nuclear spin memory. Here we present a novel approach to nanoscale magnetic sensing based on coherent control of an individual electronic spin contained in the Nitrogen-Vacancy (NV) center in diamond. At room temperature, using an ultra-pure diamond sample, we achieve shot-noise-limited detection of 3 nanotesla magnetic fields oscillating at kHz frequencies after 100 seconds of signal averaging. Furthermore, we experimentally demonstrate nanoscale resolution using a diamond nanocrystal of 30 nm diameter for which we achieve a sensitivity of 0.5 microtesla / Hz<sup>1/2</sup>.
