SAGTA: Semi-automatic Ground Truth Annotation in crowd scenes (2014)

Ground truth is crucial in the performance evaluation of algorithms. Nevertheless, it is a tedious and time-consuming task to annotate ground truth manually, especially in crowd scenes. In this paper, we propose a novel semi-automatic tool called SAGTA (Semi-automatic Ground Truth Annotation Tool), which can assist researchers to annotate pedestrians easily and quickly in crowd scenes. Firstly, users label pedestrians manually in a few key frames by drawing bounding boxes through the friendly GUI of SAGTA. Then, the annotations in the rest frames are coarsely estimated by automatically interpolating based on 3D linear motion assumption. Moreover, our tool refines the estimated annotations through using ORB feature matching. This coarse-to-fine method facilitates the annotation process efficiently. Afterwards, the refined annotations are manually verified and corrected to guarantee the accuracy of annotations. In addition, some extra information (such as density, trajectory and occlusion relationships) can be inferred automatically and visualized vividly. The proposed tool has been tested on PETS and real surveillance data sets. Experimental results demonstrate that SAGTA achieves superior performance in time cost than ViPER-GT, which is the widely used annotation tool.
Central nervous system depressants. 14. <i>As</i>‐triazino‐1,4‐benzodiazepines (1977)

Abstract Seven series of as ‐triazino[4,3‐ a ] [1,4]benzodiazepines were prepared which differed in the degree of unsaturation or the nature and position of oxygen function on the triazino ring. These were prepared by closing the triazino ring of appropriately substituted hydrazones from 2‐hydrazinobenzodiazepines or by condensing substituted hydrazines with 2‐thiobenzodiazepines. Most of these represent new ring systems. They were tested in a battery of tests designed to uncover central nervous system activities. Most of the activity was found in tests thought to be indicative of anxiolytic, hypnotic or sedative potential. Five of the series contained members more active than the standard, diazepam, and a few of the compounds were among the most potent benzodiazepines known. Some of the intermediate benzodiazepine hydrazones were also active.
Proposed Architecture to manage critical states predictions in IoT applications (2017)

In IoT applications, data from various sensors are processed and delivered in different structures and formats (JSON, XML, CSV etc) so a noSQL database is a good approach for a persistence layer. Analyzing sensors data evolutions could predict critical states in a system (infarction, stoke, hyperglycemic coma). The data analysis in noSQL databases is time-consuming and not effective in real time decision. This paper present a new layer as a persistence layer wrapper which will separate sensor data into two DBMS focused on different performances and purposes. All data will be stored in a noSQL database. Data used for critical states predictions will be selected and stored in a fast, SQL DBMS and adequate algorithms will be used to manage them.
Nonlinear filtering and smoothing: An introduction to martingales, stochastic integrals, and estimation (1984)

Most useful for graduate students in engineering and finance who have a basic knowledge of probability theory, this volume is designed to give a concise understanding of martingales, stochastic integrals, and estimation. It emphasizes applications. Many theorems feature heuristic proofs; others include rigorous proofs to reinforce physical understanding. Numerous end-of-chapter problems enhance the book's practical value.After introducing the basic measure-theoretic concepts of probability and stochastic processes, the text examines martingales, square integrable martingales, and stopping time
Design and evaluation of a DAMQ multiprocessor network with self-compacting buffers (1994)

This paper describes a new approach to implement Dynamically Allocated Multi-Queue (DAMQ) switching elements using a technique called buffers. This technique is efficient in that the amount of hardware required to manage the buffers is relatively small; it offers high performance since it is an implementation of a DAMQ. The first part of this paper describes the self-compacting buffer architecture in detail, and compares it against a competing DAMQ switch design. The second part presents extensive simulation results comparing the performance of a self-compacting buffer switch against an ideal switch including several examples of k-ary n-cubes and delta networks. In addition, simulation results show how the performance of an entire network can be quickly and accurately approximated by simulating just a single switching element.
Evaluation of phenotypic and functional stability of RAW 264.7 cell line through serial passages (2018)

Established cell lines are widely used in research, however an appealing question is the comparability of the cells between various laboratories, their characteristics and stability in time. Problematic is also the cell line misidentification, genetic and phenotypic shift or Mycoplasma contamination which are often forgotten in research papers. The monocyte/macrophage-like cell line RAW 264.7 has been one of the most commonly used myeloid cell line for more than 40 years. Despite its phenotypic and functional stability is often discussed in literature or at various scientific discussion panels, their stability during the consecutive passages has not been confirmed in any solid study. So far, only a few functional features of these cells have been studied, for example their ability to differentiate into osteoclasts. Therefore, in the present paper we have investigated the phenotype and functional stability of the RAW 264.7 cell line from passage no. 5 till passage no. 50. We found out that the phenotype (expression of particular macrophage-characteristic genes and surface markers) and functional characteristics (phagocytosis and NO production) of RAW 264.7 cell line remains stable through passages: from passage no. 10 up to passage no. 30. Overall, our results indicated that the RAW 264.7 cell line should not be used after the passage no. 30 otherwise it may influence the data reliability.
On-die CMOS leakage current sensor for measuring process variation in sub-90nm generations (2004)

This paper describes an on-die leakage current sensor in 1.2V, 90nm CMOS technology for accurately measuring process variation. Results based on measured leakage data show (i) higher signal-to-noise ratio and (ii) reduced sensitivity to supply and P/N skew variations compared to prior designs, while the proposed sensor only requires a single bias generator even for multi-bit resolution sensing. A 6-channel leakage current monitor testchip fabricated in 90nm dual-Vt CMOS is also described.
Spectrum analysis with a c.c.d. delay line (1977)

A novel form of c.c.d. spectrum analyser is described which functions by performing the discrete Fourier transform. The approach is based on the coherent-memory-filter principle and is well suited to Doppler processing. Results are given for a 10 kHz analyser with 200 Hz resolution.
A MEMS acoustic energy harvester (2006)

This paper presents the development of a micromachined acoustic energy harvester for aeroacoustic applications. The acoustic energy harvester employs a silicon-micromachined circular, piezoelectric composite diaphragm for electroacoustic transduction. Lumped element modeling, design, fabrication and characterization of a micromachined acoustic energy harvester prototype are presented. Experimental results indicate a maximum output power density of 0.34 µW cm−2 at 149 dB (ref. 20 µPa) and suggest a potential output power density, for this design, of 250 µW cm−2 with an improved fabrication process.
Dosimetry with a diamond operating as a resistor (1981)

A very pure diamond with contacts of graphite has a linear current-voltage characteristic when subjected to irradiation. The resistivity is inversely proportional to the dose rate and the sensitivity is extremely high for gamma- and X-rays and electron beams. It is concluded that diamond resistors are suitable for clinical radiation dosimetry. This conclusion is also based on earlier work in which diamonds were used as pinpoint counters.
Fluorescence Depolarization Measurements on Pyrene Butyric-Bovine Serum Albumin Conjugates (1967)

Learning Deep Object Detectors from 3D Models (2014)

Crowdsourced 3D CAD models are becoming easily accessible online, and can potentially generate an infinite number of training images for almost any object category.We show that augmenting the training data of contemporary Deep Convolutional Neural Net (DCNN) models with such synthetic data can be effective, especially when real training data is limited or not well matched to the target domain. Most freely available CAD models capture 3D shape but are often missing other low level cues, such as realistic object texture, pose, or background. In a detailed analysis, we use synthetic CAD-rendered images to probe the ability of DCNN to learn without these cues, with surprising findings. In particular, we show that when the DCNN is fine-tuned on the target detection task, it exhibits a large degree of invariance to missing low-level cues, but, when pretrained on generic ImageNet classification, it learns better when the low-level cues are simulated. We show that our synthetic DCNN training approach significantly outperforms previous methods on the PASCAL VOC2007 dataset when learning in the few-shot scenario and improves performance in a domain shift scenario on the Office benchmark.
Precise delay generation using coupled oscillators (1993)

A new delay generator based on a series of coupled ring oscillators has been developed; it produces precise delays with subgate delay resolution for chip testing applications. It achieves a delay resolution equal to a buffer delay divided by the number of rings. The coupling employed forces the outputs of a linear array of ring oscillators oscillating at the same frequency to be uniformly offset in phase by a precise fraction of a buffer delay. The buffer stage used in the ring oscillators is based on a source-coupled pair and achieves high supply noise rejection while operating at low supply voltages. Experimental results from a 2- mu m N-well CMOS implementation of the delay generator demonstrate that it can achieve an output delay resolution of 101 ps while operating at 141 MHz with a peak error of 58 ps.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Discovery of specific targeting ligands as the biomarkers for colorectal cancer (2018)

Aim: Targeted diagnosis and therapy for colorectal cancer (CRC) is limited by the lack of specific biomarkers. Our aim was to discover CRC-specific targeting ligands using a one-bead one-compound (OBOC) combinatorial library. Method: Samples of OBOC peptide libraries were color coded, mixed and incubated with commercially available human CRC cells (HT-29 and DLD-1). Libraries with compound beads that bound to CRC cells were selected for further screening. Compound beads that bound to both CRC cells were screened with human colonic epithelial cells to select beads that bound only to CRC cells but not to human colonic epithelial cells. Chemical structures of the positive peptides were determined by Edman chemistry. CRC-targeted imaging agents were developed by conjugation of CRC binding peptide with biotin through a hydrophilic linker and then complexed with streptavidin–Cy5.5. Immunohistochemistry studies were used to evaluate CRC detection efficacy. Targeting specificity was further tested with subcutaneous CRC xenografts in nude mice. Results: Two cyclic peptides, CRC-6 and CRC-9, composed of natural and unnatural amino acids, bind specifically to CRC cells with moderately high affinity and specificity. CRC-9 is able to detect CRC cells grown on chamber slides at the concentration of 1 µM after 30 min incubation. Tail vein injection of 1.8 nmol biotinylated peptide CRC-9, complexed with streptavidin–Cy5.5 (SA–Cy5.5), is able to target the subcutaneous CRC xenograft implants in nude mice. None of the two peptides showed cytotoxic effect on human blood cells, up to the concentration of 500 µM. Conclusion: CRC-9 has the potential to be developed as an effective biomarker for improving the management of CRC patients by enhancing the efficiency of detection and efficacy of targeting treatment.
Cardiac ryanodine receptor in metabolic syndrome: is JTV519 (K201) future therapy? (2012)

Metabolic syndrome is characterized by a combination of obesity, hypertension, insulin resistance, dyslipidemia, and impaired glucose tolerance. This multifaceted syndrome is often accompanied by a hyperdynamic circulatory state characterized by increased blood pressure, total blood volume, cardiac output, and metabolic tissue demand. Experimental, epidemiological, and clinical studies have demonstrated that patients with metabolic syndrome have significantly elevated cardiovascular morbidity and mortality rates. One of the main and frequent complications seen in metabolic syndrome is cardiovascular disease. The primary endpoints of cardiometabolic risk are coronary and peripheral arterial disease, myocardial infarction, congestive heart failure, arrhythmia, and stroke. Alterations in expression and/or functioning of several key proteins involved in regulating and maintaining ionic homeostasis can cause cardiac disturbances. One such group of proteins is known as ryanodine receptors (intracellular calcium release channels), which are the major channels through which Ca(2+) ions leave the sarcoplasmic reticulum, leading to cardiac muscle contraction. The economic cost of metabolic syndrome and its associated complications has a significant effect on health care budgets. Improvements in body weight, blood lipid profile, and hyperglycemia can reduce cardiometabolic risk. However, constant hyperadrenergic stimulation still contributes to the burden of disease. Normalization of the hyperdynamic circulatory state with conventional therapies is the most reasonable therapeutic strategy to date. JTV519 (K201) is a newly developed 1,4-benzothiazepine drug with antiarrhythmic and cardioprotective properties. It appears to be very effective in not only preventing but also in reversing the characteristic myocardial changes and preventing lethal arrhythmias. It is also a unique candidate to improve diastolic heart failure in metabolic syndrome.
Comprehensive Evaluation of Competitiveness of Listed Companies Using Artificial Neural Network (2010)

Based on the annual report data between 1995 and 2005 of all listed companies (LCs), the 25 initial financial indexes, widely used by experts and researchers aboard and at home, was deduced to 14 effective evaluation indicators using factor analysis and principal component analysis (PCA). The 14 evaluation indicators, covering five aspects for comprehensive evaluation of competitiveness of LC, retain 85% variance of the 25 initial indexes. An evaluation criteria system with 14 indicators for evaluating the competitiveness of LCs was thus put forward in this paper. Artificial neural networks (ANNs) were used to comprehensively evaluate the competitiveness of LC. The training set data, verification set data and testing set data were generated according to the evaluation criteria system for training, monitoring the training process on-line and judging the performance of the ANNs model. The verification set data was used to monitor the training process to escape from the over-training and the global minimum was reached eventually. The eleven LCs mainly related to communication and culture industries were comprehensively evaluated as examples. The case study results show that the criteria are reasonable and the process of establishing the ANNs model is reliable, feasible and proper.
The role of Auger recombination in the temperature-dependent output characteristics (T=∞) of p-doped 1.3 μm quantum dot lasers (2004)

Temperature invariant output slope efficiency and threshold current (T0=∞) in the temperature range of 5–75 °C have been measured for 1.3 μm p-doped self-organized quantum dot lasers. Similar undoped quantum dot lasers exhibit T0=69K in the same temperature range. A self-consistent model has been employed to calculate the various radiative and nonradiative current components in p-doped and undoped lasers and to analyze the measured data. It is observed that Auger recombination in the dots plays an important role in determining the threshold current of the p-doped lasers.
Adjoints and importance in rendering: An overview (2003)

This survey gives an overview of the use of importance, an adjoint of light, in speeding up rendering. The importance of a light distribution indicates its contribution to the region of most interest-typically the directly visible parts of a scene. Importance can therefore be used to concentrate global illumination and ray tracing calculations where they matter most for image accuracy, while reducing computations in areas of the scene that do not significantly influence the image. In this paper, we attempt to clarify the various uses of adjoints and importance in rendering by unifying them into a single framework. While doing so, we also generalize some theoretical results-known from discrete representations-to a continuous domain.

A semantic meta-modelling approach to schema transformation (1995)

This paper presents an intermediate meta-model that consists of a set of generic meta-classes that capture and describe the semantics of a variety of data models. A model is described by a set of intermediate model meta-classes (organized in the form of a directed acyclic graph (DAG) to achieve extensibility y), while irtst antes of these meta-classes are used to describe a schema in a given data model. The proposed approach supports dynamic meta-schema comparison and transformation by employing special-purpose transformation rules.
Magnetic Resonance Angiography of the Pelvis and Lower Extremities: Works in Progress (1992)

Two-dimensional time-of-flight (TOF) magnetic resonance angiography (MRA) of the lower extremities has recently been rediscovered as a technique that can be used to find small vessels in the foot and leg for surgical revascularization in patients with severe peripheral vascular disease. The purpose of this article is to acquaint the reader with some of the common problems that may be encountered in this imaging technique and to show their derivations and solutions were applicable. In addition, the authors show receiver operator curve analysis of one radiologist's ability to determine the location and patency of arteries using this technique to be outstanding (AZ, 0.9737). This represents a promising new technique for imaging the arterial system in patients with severe peripheral vascular disease.
Index Cache Consistency in Client-Server Database Systems (2006)

In this paper, we present an enhanced cacheconsistency (concurrency-control and replicamanagement) protocol and B±tree algorithms for clientserver database management systems in which the physical database is organized as a sparse (B±tree) index. We improve the concurrency-control and the callback-locking (for replica-management) protocols by augmenting these protocols with the U-locking protocol. In our cache-consistency protocol, concurrency control and replica management are performed at the page level. Our cache consistency protocol and B±tree algorithms improve concurrency in client-server database system.
Provenance-based Integrity Protection for Windows (2015)

Existing malware defenses are primarily reactive in nature, with defenses effective only on malware that has previously been observed. Unfortunately, we are witnessing a generation of stealthy, highly targeted exploits and malware that these defenses are unprepared for. Thwarting such malware requires new defenses that are, by design, secure against unknown malware. In this paper, we present Spif, an approach that defends against malware by tracking code and data origin, and ensuring that any process that is influenced by code or data from untrusted sources will be prevented from modifying important system resources, and interacting with benign processes. Spif is designed for Windows, the most widely deployed desktop OS, and the primary platform targeted by malware. Spif is compatible with all recent Windows versions (Windows XP to Windows 10), and supports a wide range of feature rich, unmodified applications, including all popular browsers, office software and media players. Spif imposes minimal performance overheads while being able to stop a variety of malware attacks, including Stuxnet and the recently reported Sandworm malware. An open-source implementation of our system is available.
Flagellar proteins and type III‐exported virulence factors are the predominant proteins secreted into the culture media of <i>Salmonella typhimurium</i> (1999)

We analysed all major proteins secreted into culture media from Salmonella typhimurium. Proteins in culture supernatants were collected by trichloroacetic acid precipitation, separated in SDS-polyacrylamide gels and analysed by amino acid sequencing. Wild-type strain SJW1103 cells typically gave rise to nine bands in SDS gels: 89, 67, 58, 52, 50, 42, 40, 35 and (sometimes) 28 kDa. A search of the sequences in the available databases revealed that they were either flagellar proteins or virulence factors. Six of them were flagella specific: FlgK or HAP1 (58 kDa), FliC or flagellin (52 kDa), FliD or HAP2 (50 kDa), FlgE or hook protein (42 kDa), FlgL or HAP3 (35 kDa) and FlgD or hook-cap protein (28 kDa). The other four bands were specific for virulence factors: SipA (89 kDa), SipB (67 kDa), SipC (42 kDa) and InvJ (40 kDa). The 42 kDa band was a mixture of FlgE and SipC. We also analysed secreted proteins from more than 30 flagellar mutants, and they were categorized into four groups according to their band patterns: wild type, mot type, polyhook type and master gene type. Virulence factors were constantly secreted at a higher level in all flagellar mutants except a deltamot (motAB deletion) mutant, in which the amounts were greatly reduced. A new morphological pathway of flagellar biogenesis including protein secretion is presented.
Recreating the Past (2015)

New results from the investigations I carried out during the last few years on ceramic material coming from one of the most important tholos tombs built in Protopalatial times (MM IB–MM IIB), namely the main tomb of Kamilari cemetery, have been crucial in understanding the chronology and function of those Mesara tholos tombs, which have yielded MM I–II ceramic. Despite the fact that it is widely agreed that the phenomenon of the Mesara tholos tombs continued from Prepalatial through Protopala...
