Randomized trees for human pose detection (2008)

This paper addresses human pose recognition from video sequences by formulating it as a classification problem. Unlike much previous work we do not make any assumptions on the availability of clean segmentation. The first step of this work consists in a novel method of aligning the training images using 3D Mocap data. Next we define classes by discretizing a 2D manifold whose two dimensions are camera viewpoint and actions. Our main contribution is a pose detection algorithm based on random forests. A bottom-up approach is followed to build a decision tree by recursively clustering and merging the classes at each level. For each node of the decision tree we build a list of potentially discriminative features using the alignment of training images; in this paper we consider Histograms of Orientated Gradient (HOG). We finally grow an ensemble of trees by randomly sampling one of the selected HOG blocks at each node. Our proposed approach gives promising results with both fixed and moving cameras.
Cloning and sequencing of a gene for Mucor rennin, an aspartate protease from<i>Mucor pusillus</i> (1986)

The aspartate protease of Mucor pusillus (Mucor pusillus rennin; MPR) is a milk-clotting enzyme used in the cheese industry. The partial amino acid sequence of MPR was determined and oligonucleotide probes were synthesized for cloning of the MPR gene. A clone giving positive hybridization with the probes was selected from the cosmid library. Sequencing of the cloned DNA revealed an open reading frame of 1281 bp without introns which encodes 361 amino acids for the expected MPR with an NH2-terminal extension of 66 amino acids. MPR seems to be synthesized as a prepro enzyme.
The In-Plane Anisotropy of WTe2 Investigated by Angle-Dependent and Polarized Raman Spectroscopy (2016)

Tungsten ditelluride (WTe2) is a semi-metallic layered transition metal dichalcogenide with a stable distorted 1T phase. The reduced symmetry of this system leads to in-plane anisotropy in various materials properties. We have systemically studied the in-plane anisotropy of Raman modes in few-layer and bulk WTe2 by angle-dependent and polarized Raman spectroscopy (ADPRS). Ten Raman modes are clearly resolved. Their intensities show periodic variation with sample rotating. We identify the symmetries of the detected modes by quantitatively analyzing the ADPRS results based on the symmetry selection rules. Material absorption effect on the phonon modes with high vibration frequencies is investigated by considering complex Raman tensor elements. We also provide a rapid and nondestructive method to identify the crystallographic orientation of WTe2. The crystallographic orientation is further confirmed by the quantitative atomic-resolution force image. Finally, we find that the atomic vibrational tendency and complexity of detected modes are also reflected in the shrinkage degree defined based on ADPRS, which is confirmed by corresponding density functional calculation. Our work provides a deep understanding of the interaction between WTe2 and light, which will benefit in future studies about the anisotropic physical properties of WTe2 and other in-plane anisotropic materials.
Screening of Turkish Melon Accessions for Resistance to ZYMV, WMV and CMV (2010)

In the Çukurova University Department of Horticulture more than 350 melon accessions were collected from different ecological parts of Turkey which is located on the secondary genetic diversification center of this crop, and their characterization studies are near completion. Furthermore, evaluation studies of these materials have started. In the present study 67 melon accessions, sampled from this germplasm, were tested for resistance to zucchini yellow mosaic virus (ZYMV), Cucumber mosaic virus (CMV) and watermelon mosaic virus (WMV). After resistance tests made by mechanical inoculation, four accessions (‘CU 100’, ‘CU 287’, ‘CU 305’ and ‘CU 328’) were found resistant to ZYMV and three accessions (‘CU 305’, ‘C 264’, and ‘C 276’) to WMV. No resistant genotype was found to CMV.
Getting More from Segmentation Evaluation (2012)

We introduce a new segmentation evaluation measure, WinPR, which resolves some of the limitations of WindowDiff. WinPR distinguishes between false positive and false negative errors; produces more intuitive measures, such as precision, recall, and F-measure; is insensitive to window size, which allows us to customize near miss sensitivity; and is based on counting errors not windows, but still provides partial reward for near misses. 1

Substrate fed logic - An improved form of injection logic (1974)

A novel form of integrated injection logic is described which has significant advantages over its conventional counterpart in packing density and power-delay product. The structure is formed from two epitaxial layers on a heavily doped p type substrate. The p type epitaxial layer, which forms the base of the npn transistor, is lightly doped, allowing the fabrication of Schottky contacts. This gives rise to an extremely powerful multi-input, multi-output logic element on a single base land. The fundamental SFL structure has been successfully demonstrated. Gates and a ring oscillator have been operated and a reduction in power-delay product has been shown. A viable technology for Schottky Barrier Diodes has been demonstrated and an optimised structure has been designed.

Synthesis and pharmacological evaluation of N'-morpholinomethylurea derivatives with platelet antiaggregant activity. (1981)

In the attempt to prolong and stabilize the known antiaggregant activity of morpholinomethylurea (MMU) derivatives were prepared with carboxylic acids possessing antiaggregant, anti-inflammatory or hypolipemic activity. The results of the experiments showed the important anti-aggregant and hypolipemic activity of N-2-(p-chlorophenoxy)-isobutyryl-N'-morpholinomethylurea (plafibride, ITA 104). The results obtained seem to indicate that the activity of these new N-acyl-N'-MMU is due initially to the molecule per se although it cannot be totally ruled out that part of the pharmacodynamic effect of the MMU may depend on a prodrug-like behaviour.
Determination of the Optimal Delay between Sonications during Focused Ultrasound Surgery in Rabbits by Using MR Imaging to Monitor Thermal Buildup in Vivo (1999)

MR imaging can be used to monitor thermal buildup and its effects due to sequential, neighboring sonications in vivo to produce evenly shaped regions of tissue coagulation. The temperature information obtained from the monitoring can be used to optimize the intersonication delay for any set of ultrasound and tissue parameters.
The effect of hemodialysis, vitamin D metabolites and renal transplantation on the skeletal demineralization associated with renal osteodystrophy: a computerized histomorphometric analysis. (1986)

Twenty-three patients with end-stage renal failure treated by hemodialysis or transplantation were followed for up to 10 years. Sequential full thickness iliac crest bone biopsies were obtained to assess the effects on bone disease of hemodialysis, treatment with 1,25-dihydroxycholecalciferol [1,25-(OH)2D3] and 24,25-dihydroxycholecalciferol [24,25-(OH)2D3] and renal transplantation. The biopsies were analyzed by a computerized histomorphometric technique which allowed accurate measurements of calcified bone and osteoid areas. Serum aluminum and parathyroid hormone concentrations were also monitored. Hemodialysis was associated with a loss of calcified bone and an increase in osteoid areas. The progressive bone loss was arrested but not reversed following treatment with either 1,25-(OH)2D3 or 24,25-(OH)2D3. Osteoid area was unchanged or reduced following treatment with 1,25-(OH)2D3 in all but three patients who had serum aluminum concentrations in excess of 5 mumol/l. 24,25-(OH)2D3 was not effective in reducing osteoid area, and combined treatment with 1,25 and 24,25-(OH)2D3 had no effect beyond that expected with 1,25-(OH)2D3 alone. Bone biopsies showed loss of calcified bone and an increase in osteoid areas one year and more after successful renal transplantation in five patients. Nineteen of the 23 patients developed serum aluminum concentrations greater than 3 mumol/l, probably because of the use of oral aluminum hydroxide as a phosphate binding agent. In these patients serum parathyroid hormone concentrations greater than 600 pg/ml appeared to prevent the development of osteopenia.
Relationship Between Earth-Science Education and Spatial Visualization (1997)

The purpose of this study was to look for interrelations between the study of introductory geology courses and the development of spatial-visualization ability. The study was conducted among 32 undergraduate students during their first year of earth sciences study in the Hebrew University of Jerusalem. The students' spatial-visualization ability was measured at the beginning and at the end of the course by two different validated instruments. Pre- and post-geology scores were analyzed for any significant change and for correlation with final scores in the course. Results indicated that the students' spatial-visualization ability significantly improved after the first geology course was taken. Interviews revealed that the students claimed that only the earth-science courses required spatial-visualization skills. It is suggested that there is a two-way relationship between studying earth science and spatial-visualization skills. It seems that studying earth science itself might improve student spatial-visualization aptitude. The findings also support the notion that males develop better spatial-visualization skills.
A Scalable Architecture for Distributed Transmit Beamforming with Commodity Radios: Design and Proof of Concept (2013)

We describe a fully-wireless prototype of distributed transmit beamforming on a software-defined radio platform. Distributed beamforming is a cooperative transmission technique that can achieve orders of magnitude increases in range or energy efficiency of wireless communication systems. However, this technique requires precise synchronization of the radio frequency signal from each transmitter. The significance of our prototype is in demonstrating that this requirement can be satisfied using digital signal processing methods on commodity hardware with low-quality oscillators. Our synchronization approach scales to large numbers of transmitters: each transmitter runs independent algorithms based on periodically transmitted feedback packets from the receiver. A key simplification is the decoupling of the algorithms for frequency locking and beamsteering at each transmitter, even though both processes use the same feedback packets. Frequency locking employs an Extended Kalman filter to track the local oscillator offset between a transmitter and the receiver, using frequency offset measurements based on the feedback packet it waveform, while the phase adjustments for beamsteering are determined using a one-bit feedback algorithm based on the feedback packet it payload. Our prototype demonstrates that distributed transmit beamforming can be incorporated into wireless networks without requiring hardware innovations, and provides open-source building blocks for future research and development.
A multicast tree algorithm considering maximum delay bound for real-time applications (2002)

For many multimedia multicast applications, especially those requiring real-time traffic, it is important that the maximum delay bound requirement between any pair of group members be satisfied. Most studies on multicast routing have been based on a single multicast tree (a shortest path tree or a minimal Steiner tree) approach. By using only a single multicast tree for a multicast group, satisfying the maximum delay bound requirement is nearly impossible. To fulfill these requirement, we adopt the multiple multicast tree concept whose disadvantage is the high tree maintenance cost. Since the tree maintenance cost is proportional to the number of multicast trees for a multicast group, it is necessary to minimize the number of multicast trees. In this paper, we formulate the delay-bounded multicast tree (DBMT) problem whose main objectives are to satisfy an application's maximum delay bound among the group members and to minimize the number of multicast trees needed for a group communication. We categorize the DBMT problem according applications' needs into two subproblems, the shortest path tree-based DBMT (SPT DBMT) and the minimal Steiner tree-based DBMT (MST DBMT) problems. For the DBMT subproblems, we prove the NP-hardness and propose heuristic algorithms. For the performance analysis, simulations were performed.
<title>Comparative evaluation of optical and conventional approaches for array antenna beamforming</title> (1995)

Microwave radar array antennas generally employ a beamformer which functions as the interface between the array elements and the transmitter-receiver, distributing signals to the array elements on transmit, and coherently combining the elemental signal components on receive. A conventional beamformer typically consists of corporate feed manifolds comprised of waveguide or coaxial cables, stripline combiner circuits, etc. These manifolds grow increasingly large and heavy in proportion to the number of elements in the array. Optical bemaformers, which utilize manifolds made up of optical fibers, promise a lightweight and very compact alternative approach. In an optoelectronic implementation the electrical signals are first converted to a modulation on an optical carrier frequency, and then the distribution and combining manifolds are configured with optical fibers. This paper compared conventional and optical implementations for a large, dual band (S and UHF) radar array. A detailed dual band beamformer design is developed for each technology and the two designs are compared with respect to weight, volume and power consuption. Both designs meet the same set of dynamic range, noise figure, bandwidth, power output, and sidelobe weighting requirements.
Sequence Similarity Between the 73-Kilodalton Protein of Mammalian CPSF and a Subunit of Yeast Polyadenylation Factor I (1996)

The 3' ends of most eukaryotic messenger RNAs are generated by endonucleolytic cleavage and polyadenylation. In mammals, the cleavage and polyadenylation specificity factor (CPSF) plays a central role in both steps of the processing reaction. Here, the cloning of the 73-kilodalton subunit of CPSF is reported. Sequence analyses revealed that a yeast protein (Ysh1) was highly similar to the 73-kD polypeptide. Ysh1 constitutes a new subunit of polyadenylation factor I (PFI), which has a role in yeast pre-mRNA 3'-end formation. This finding was unexpected because in contrast to CPSF, PFI is only required for the polyadenylation reaction. These results contribute to the understanding of how 3'-end processing factors may have evolved.

Time-resolved hyperspectral single-pixel camera implementation for compressive wide-field fluorescence lifetime imaging (2016)

Single-pixel imaging based on compressive sensing theory has been a highlighted technique in the biomedical imaging field for many years. This interest has been driven by the possibility of performing microscopic or macroscopic imaging based on low-cost detector arrays, increased SNR (signal-to-noise ratio) in the acquired data sets and the ability to perform high quality image reconstruction with compressed data sets by exploiting signal sparsity. In this work, we present our recent work in implementing this technique to perform time domain fluorescence-labeled investigations in preclinical settings. More precisely, we report on our time-resolved hyperspectral single-pixel camera for fast, wide-field mapping of molecular labels and lifetime-based quantification. The hyperspectral single-pixel camera implements a DMD (Digital micro-mirror device) to generate optical masks for modulating the illumination field before it is delivered onto the sample and focuses the emission light signals into a multi-anode hyperspectral time-resolved PMT (Photomultiplier tube) to acquire spatial, temporal and spectral information enriched 4-D data sets. Fluorescence dyes with lifetime and spectral contrast are embedded in well plates and thin tissues. L-1 norm based regularization or the least square method, is applied to solve the underdetermined inverse problem during image reconstruction. These experimental results prove the possibility of fast, wide-field mapping of fluorescent labels with lifetime and spectral contrast in thin media.
Intermediate Data Caching Optimization for Multi-Stage and Parallel Big Data Frameworks (2018)

In the era of big data and cloud computing, large amounts of data are generated from user applications and need to be processed in the datacenter. Data-parallel computing frameworks, such as Apache Spark, are widely used to perform such data processing at scale. Specifically, Spark leverages distributed memory to cache the intermediate results, represented as Resilient Distributed Datasets (RDDs). This gives Spark an advantage over other parallel frameworks for implementations of iterative machine learning and data mining algorithms, by avoiding repeated computation or hard disk accesses to retrieve RDDs. By default, caching decisions are left at the programmer's discretion, and the LRU policy is used for evicting RDDs when the cache is full. However, when the objective is to minimize total work, LRU is woefully inadequate, leading to arbitrarily suboptimal caching decisions. In this paper, we design an algorithm for multi-stage big data processing platforms to adaptively determine and cache the most valuable intermediate datasets that can be reused in the future. Our solution automates the decision of which RDDs to cache: this amounts to identifying nodes in a direct acyclic graph (DAG) representing computations whose outputs should persist in the memory. Our experiment results show that our proposed cache optimization solution can improve the performance of machine learning applications on Spark decreasing the total work to recompute RDDs by 12%.
<i>In vitro</i>susceptibility patterns of<i>Aspergillus</i>and<i>Fusarium</i>species isolated from equine ulcerative keratomycosis cases in the midwestern and southern United States with inclusion of the new antifungal agent voriconazole (2009)

Based on in vitro evidence, voriconazole appears to be the most effective antifungal for initial treatment of equine keratomycosis in the midwestern and southern United States. Results are comparable with previous studies in that isolated fungi from equine keratomycosis cases showed consistently poor susceptibility to fluconazole. Organisms isolated in different geographic locations of the midwestern and southern United States appeared to have similar patterns of antifungal susceptibility.
A Ratiometric Fluorescence Imaging System for Surgical Guidance (2008)

A 3‐chip CCD imaging system has been developed for quantitative in vivo fluorescence imaging. This incorporates a ratiometric algorithm to correct for the effects of tissue optical absorption and scattering, imaging “geometry” and tissue autofluorescence background. The performance was characterized, and the algorithm was validated in tissue‐simulating optical phantoms for quantitative measurement of the fluorescent molecule protoporphyrin IX (PpIX). The technical feasibility to use this system for fluorescence‐guided surgical resection of malignant brain tumor tissue was assessed in an animal model in which PpIX was induced exogenously in the tumor cells by systemic administration of aminolevulinic acid (ALA).
