Online template induction for machine-generated emails (2019)

In emails, information abounds. Whether it be a bill reminder, a hotel confirmation, or a shipping notification, our emails contain useful bits of information that enable a number of applications. Most of this email traffic is machine-generated, sent from a business to a human. These business-to-consumer emails are typically instantiated from a set of email templates, and discovering these templates is a key step in enabling a variety of intelligent experiences. Existing email information extraction systems typically separate information extraction into two steps: an offline template discovery process (called template induction) that is periodically run on a sample of emails, and an online email annotation process that applies discovered templates to emails as they arrive. Since information extraction requires an email's template to be known, any delay in discovering a newly created template causes missed extractions, lowering the overall extraction coverage. In this paper, we present a novel system called Crusher that discovers templates completely online, reducing template discovery delay from a week (for the existing MapReduce-based batch system) to minutes. Furthermore, Crusher has a resource consumption footprint that is significantly smaller than the existing batch system. We also report on the surprising lesson we learned that conventional stream processing systems do not present a good framework on which to build Crusher. Crusher delivers an order of magnitude more throughput than a prototype built using a stream processing engine. We hope that these lessons help designers of stream processing systems accommodate a broader range of applications like online template induction in the future.
Estrogen Receptor Gene Analysis in Estrogen Receptor-Positive and Receptor-Negative Primary Breast Cancer (1995)

The correlation reported previously, as well as our current findings, suggest that further investigations are warranted to understand the possible linkage of the ER gene locus to hereditary breast cancer.
Use case visual Bag-of-Words techniques for camera based identity document classification (2015)

Nowadays, automatic identity document recognition, including passport and driving license recognition, is at the core of many applications within the administrative and service sectors, such as police, hospitality, car renting, etc. In former years, the document information was manually extracted whereas today this data is recognized automatically from images obtained by flat-bed scanners. Yet, since these scanners tend to be expensive and voluminous, companies in the sector have recently turned their attention to cheaper, small and yet computationally powerful scanners: the mobile devices. The document identity recognition from mobile images enclose several new difficulties w.r.t traditional scanned images, such as the loss of a controlled background, perspective, blurring, etc. In this paper we present a real application for identity document classification of images taken from mobile devices. This classification process is of extreme importance since a prior knowledge of the document type and origin strongly facilitates the subsequent information extraction. The proposed method is based on a traditional Bagof-Words in which we have taken into consideration several key aspects to enhance recognition rate. The method performance has been studied on three datasets containing more than 2000 images from 129 different document classes.
Gradient based nonuniform subsampling for information-theoretic alignment methods (2005)

We examine the computation of information-theoretic image registration metrics and propose two (deterministic and stochastic) nonuniform subsampling methods for improving the efficiency. The proposed schemes attempt to use only the most relevant information as the basis of the computation. Both methods are shown to yield considerable improvement over the current practice of uniform subsampling. Theoretical and experimental evidence is provided.
Synthesis of 3,3- and 4,4-Alkyl-phenyl-substituted Pyrrolidin-2-one Derivatives (2009)

Syntheses of 3,3- and 4,4-alkyl-phenyl-substituted pyrrolidin-2-one derivatives are described. The final compounds were obtained by the reductive cyclization of relevant cyanoalkanoate esters using NaBH 4 and CoCl 2 ·6H 2 O. The obtained pyrrolidin-2-one derivatives are pharmacophoric fragments for the synthesis of various biologically active compounds.

MU-Type Multicore Fiber Connector (2013)

We have developed a 7-core-fiber connector. To maintain both the ferrule floating mechanism and precise alignment around the ferrule axis, we employed Oldham's coupling mechanism inside an MU-type connector plug housing and realized an average attenuation of 0.13dB and an average return loss of 48.2dB.
Antiproliferative activity of retinoic acid and some novel retinoid derivatives in breast and colorectal cancer cell lines of human origin. (1993)

Antiproliferative activities of all-trans-retinoic acid (RA, CAS 302-79-4) and some retinoid derivatives (all-trans-retinyl-beta-D-glucuronide (RYG), methyl-(1-O-retinoyl-beta-D-glucopyranoside) uronate (MRG), all-trans-retinoic acid beta-D-galactopyranosyl ester (RGA), and all-trans-retinoic acid beta-D-glucopyranosyl ester (RGU)) were determined by microculture tetrazolium assay (MTT assay) and cell counting by Coulter Counter (CC) in breast (MCF7, MDA MB 231) and colon (SW 948) cancer cell lines of human origin. RA, MRG, RGU, and RGA (5, 25 mumol/l) were significantly more growth-inhibitory in MCF7 cells, which are known to be cellular retinoic acid-binding protein (cRABP) and cellular retinol binding protein (cRBP) positive, than in MDA MB 231 cells which are cRABP and cRBP negative. RYG was active only in MDA MB 231 cells. RA, MRG, RGA and RGU (25 mumol/l) stimulated the proliferation of SW 948 cells as determined by CC, whereas the MTT assay indicated an inhibition of cell growth.
Influence of Li+, Na+ and K+ cation concentrations in X and Y zeolites on isotherms and heats of adsorption of propane and water (1979)

Heats of adsorption of propane and water vapour on X and Y zeolites with varying content of exchange cations Li+, Na+ and K+ were measured in a calorimeter at ≈ 20°C. Adsorption isotherms of propane on Li- and K-forms of X and Y zeolites were measured in the temperature range 0–130°C. They are described by the virial equation. Henry's constants Kns, p, 1 calculated according to this equation, change considerably on varying the type and concentration of exchange cations in the zeolites. A decrease in exchange cation concentrations in the zeolites results in a reduction in the amount adsorbed and in the heat of adsorption, not only for water, but also for propane. The decrease in the concentration of exchange cations apparently occurs first as a result of the removal of cations from the surface of the large cavities in the zeolites (from sites III).
A comparison of various DC-DC converters and their application to power factor correction (2003)

For rectifier circuits with power factor correction, boost converters are generally used, and as a result the output voltage becomes limited. To expand the controlled voltage range, buck-boost or Cuk converter types should be utilized. This paper presents a circuit configuration with power factor correction by a third type of buck boost converter, termed a canonical switching cell. Single phase power factor correction using a buck boost converter can control the output voltage over a wide range, because it has the ability to step-up and step-down the output voltage. Firstly, this paper compares the mechanisms of the power transmission and the characteristics based on the switching ripple of various converters, in which the Luo converter is added in discussion. Secondly, the canonical switching cell is applied to the single phase power factor correction. It is shown that this converter is suitable for power factor correction.

Application of N-terminally Truncated DNA Polymerase from Thermus thermophilus ( Tth Polymerase) to DNA Sequencing and Polymerase Chain Reactions: Comparative Study of  Tth and Wild-Type Tth Polymerases (1996)

N-Terminally truncated DNA polymerase from Thermus thermophilus (delta Tth polymerase) lacking 5'-3' exonuclease activity was used for DNA sequencing and polymerase chain reaction (PCR). In contrast to the high background of the sequencing ladder observed with the wild-type Tth polymerase, delta Tth polymerase gave readable sequencing patterns which extend up to more than 500 bases from the primer site on cycle sequencing and automated sequencing. The delta Tth polymerase was used for the standard and mutagenic PCR, and net amplification of the DNA and the mutations accumulated during PCR were analyzed. Under mutagenic PCR, the mutation rates were 7.0 x 10(-4) (Tth) and 8.3 x 10(-4) (delta Tth) per nucleotide per cycle of amplification, which were 4-9 times higher than the rates under standard PCR.
Influence of air-gap length and cross-section on magnetic circuit parameters (2014)

Air-gap is one of the most crucial part of magnetic circuits, especially in high power inductors. It significantly modifies parameters of magnetic devices by increasing of saturation current, linearizes B-H curve of magnetic circuit and causes decreasing of the inductance. Therefore, the optimal selection of a shape and dimensions of air-gap is very important from designing point of view. This paper is focused on the presentation of optimal dimensions of the air-gap with rectangular cross-section as a function of air-gap length and cross-section ratio. The COMSOL Multiphysics® software was used for simulation of the magnetic field distribution for chosen cases in the exemplary magnetic circuit. The AC/DC module was applied for the calculations. By varying of the geometry parameters optimal solutions for this kind of magnetic circuit are concluded. The presented results are dedicated to magnetic designers to prepare inductor cores designs optimally.
Fabrication of dielectric optical waveguides on AlTiC sliders for heat-assisted magnetic recording (2004)

In this paper we show the feasibility to integrate waveguide optics into magnetic recording sliders using current recording head manufacturing techniques. Thin film planar waveguides were deposited on ceramic substrates and structured to yield rectangular waveguides positioned on the front face of recording sliders that fly at 20 nm spacing over a glass disk. The thin film waveguide is equipped with a diffraction grating that allows light to be coupled into the waveguide and directed towards the air bearing surface. Optical properties of selected waveguide stacks are presented together with photographs of etched waveguide structures on AlTiC sliders.
Limiting the power consumption of main memory (2007)

The peak power consumption of hardware components affects their powersupply, packaging, and cooling requirements. When the peak power consumption is high, the hardware components or the systems that use them can become expensive and bulky. Given that components and systems rarely (if ever) actually require peak power, it is highly desirable to limit power consumption to a less-than-peak power budget, based on which power supply, packaging, and cooling infrastructure scan be more intelligently provisioned.
Solute Permeation Through Hydrogel Membranes (1980)

The permeabilities of water soluble nonelectrolytes and several hydrophobic steroids in poly(hydroxyethyl methacrylate) hydrogel films were determined. The effects of crosslinking and variations in equilibrium water content of the films, on the observed permeabilities, were investigated. For hydrophilic solutes the permeation and partition coefficients are consistent with transport via the "bulk-like" water regions of the hydrogel films. These "bulk-like" water regions probably exist within the porous regions of the film. Decreases in the "bulk-like" water via copolymerization or crosslinking reduce both the partition and permeation coefficients, indicating exclusion of hydrophilic solutes from non "bulk-like" water regions. For hydrophobic solutes, permeability coefficients are smaller and partition coefficients are much larger relative to the hydrophilic solutes. For the hydrophobic solutes modelistic analysis of the permeation and partition data indicate permeation occurs predominantly by a pore-type mechanism in poly(hydroxyethyl methacrylate) and by a partition mechanism in highly crosslinked poly(hydroxyethyl methacrylate) films. The porous flux was associated with the "bulk-like" water regions of the hydrogel films and the partition flux with the collective polymer matrix, "interfacial" and "bound" water region of the films.
LoST? Appearance-Invariant Place Recognition for Opposite Viewpoints using Visual Semantics (2018)

Human visual scene understanding is so remarkable that we are able to recognize a revisited place when entering it from the opposite direction it was first visited, even in the presence of extreme variations in appearance. This capability is especially apparent during driving: a human driver can recognize where they are when travelling in the reverse direction along a route for the first time, without having to turn back and look. The difficulty of this problem exceeds any addressed in past appearance- and viewpoint-invariant visual place recognition (VPR) research, in part because large parts of the scene are not commonly observable from opposite directions. Consequently, as shown in this paper, the precision-recall performance of current state-of-the-art viewpoint- and appearance-invariant VPR techniques is orders of magnitude below what would be usable in a closed-loop system. Current engineered solutions predominantly rely on panoramic camera or LIDAR sensing setups; an eminently suitable engineering solution but one that is clearly very different to how humans navigate, which also has implications for how naturally humans could interact and communicate with the navigation system. In this paper we develop a suite of novel semantic- and appearance-based techniques to enable for the first time high performance place recognition in this challenging scenario. We first propose a novel Local Semantic Tensor (LoST) descriptor of images using the convolutional feature maps from a state-of-the-art dense semantic segmentation network. Then, to verify the spatial semantic arrangement of the top matching candidates, we develop a novel approach for mining semantically-salient keypoint correspondences.
Reasoning for video-mediated group communication (2011)

In this paper we present an approach to the reasoning required to support multi-location, multi-camera group-to-group video communication, which we call orchestration. Orchestration is akin to virtual directing: it has to ensure that each location displays the most adequate shots from all the other available sources. Its input is low-level cues extracted automatically from the AV streams. They are processed to detect higher-level events that determine the state of the communication. Directorial decisions are then inferred, reflecting social communication as well as stylistic criteria. Finally, they are transformed into camera and editing commands, directly executable by the AV infrastructure. Here, we present the architecture of the Orchestrator and sketch our rule-based approach to reasoning.
Optic Nerve Hypoplasia and Maternal Diabetes Mellitus (1986)

Altitudinal visual field defects were discovered in four young women on routine eye or general physical examinations. This led to extensive investigations because three of them were falsely presumed to have acquired disorders of the central nervous system. In each case the defect appeared to result from congenital hypoplasia of the optic nerve associated with maternal diabetes mellitus. Congenital optic nerve hypoplasia should be included in the differential diagnosis of visual field defects even when they are discovered in adults. Hypoplasia consequent to maternal diabetes mellitus is apt to be associated with excellent visual acuity and is usually an isolated defect. The female offspring of diabetic mothers may be at greater risk than the male offspring for the development of this anomaly.
Therapeutic Strategies Impacting Cancer Cell Glutamine Metabolism (2013)

The metabolic adaptations that support oncogenic growth can also render cancer cells dependent on certain nutrients. Along with the Warburg effect, increased utilization of glutamine is one of the metabolic hallmarks of the transformed state. Glutamine catabolism is positively regulated by multiple oncogenic signals, including those transmitted by the Rho family of GTPases and by c-Myc. The recent identification of mechanistically distinct inhibitors of glutaminase, which can selectively block cellular transformation, has revived interest in the possibility of targeting glutamine metabolism in cancer therapy. Here, we outline the regulation and roles of glutamine metabolism within cancer cells and discuss possible strategies for, and the consequences of, impacting these processes therapeutically.

Security Analysis and Improvements on Two Homomorphic Authentication Schemes for Network Coding (2016)

Recently, based on the homomorphic signatures, the authentication schemes, such as homomorphic subspace signature (HSS) and key predistribution-based tag encoding (KEPTE), have been proposed to resist against pollution attacks in network coding. In this paper, we show that there exists an efficient multi-generation pollution attack on HSS and KEPTE. In particular, we show that using packets and their signatures of different generations, the adversary can create invalid packets and their corresponding signatures that pass the verification of HSS and KEPTE at intermediate the nodes as well as at the destination nodes. After giving a more generic attack, we analyze the cause of the proposed attack. We then propose the improved key distribution schemes for HSS and KEPTE, respectively. Next, we show that the proposed key distribution schemes can combat against the proposed multi-generation pollution attacks. Finally, we analyze the computation and communication costs of the proposed key distribution schemes for HSS and KEPTE, and by implementing experiments, we demonstrate that the proposed schemes add acceptable burden on the system.
VR's frames of reference (1999)

This paper describes a research study that investigated how designers can use frames of reference (egocentric, exocentric, and a combination of the two) to support the mastery of abstract multidimensional information. The primary focus of this study was the relationship between FORs and mastery; the secondary focus was on other factors (individual characteristics and interaction experience) that were likely to influence the relationship between FORs and mastery. This studys outcomes (1) clarify how FORs work in conjunction with other factors in shaping mastery, (2) highlight strengths and weaknesses of different FORs, (3) demonstrate the benefits of providing multiple FORs, and (4) provide the basis for our recommendations to HCI researchers and designers.

Implications of evolution metrics on software maintenance (2002)

In the context of a hypothesis attributing the slow progress in achieving major global software process improvement, in part, to overlooking the role of feedback in that process, the FEAST/1 project is studying the impact of feedback on software evolution. Amongst its activities the project is analysing metrics of the evolution of several industrial systems, ranging from a financial transaction system to a very large real time system. The similarities which have emerged from a comparison of evolution metrics from several systems, support conclusions reached in a 1970s study of OS/360 evolution. The latest results suggest some refinement of earlier conclusions but indicate that both the metrics and the conclusions derived from them must be taken into account in the planning and implementation of successful software maintenance. Papers discussing the FEAST/1 results may accessed via the FEAST web page [fwp98].
