An Integrated Framework to Recommend Personalized Retention Actions to Control B2C E-Commerce Customer Churn (2015)

Considering the level of competition prevailing in Business-to-Consumer (B2C) E-Commerce domain and the huge investments required to attract new customers, firms are now giving more focus to reduce their customer churn rate. Churn rate is the ratio of customers who part away with the firm in a specific time period. One of the best mechanism to retain current customers is to identify any potential churn and respond fast to prevent it. Detecting early signs of a potential churn, recognizing what the customer is looking for by the movement and automating personalized win back campaigns are essential to sustain business in this era of competition. E-Commerce firms normally possess large volume of data pertaining to their existing customers like transaction history, search history, periodicity of purchases, etc. Data mining techniques can be applied to analyse customer behaviour and to predict the potential customer attrition so that special marketing strategies can be adopted to retain them. This paper proposes an integrated model that can predict customer churn and also recommend personalized win back actions.
Enzyme-Linked Immunosorbent Assay for Quantifying Antigens of Dermatophagoides farinae and D. pteronyssinus (Acari: Pyroglyphidae) in House Dust Samples (1990)

Double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) using a monoclonal antibody as capture and detector antibodies was developed for quantifying antigens of Dermatophagoides farinae Hughes and D. pteronyssinus (Trouessart) mites contained in house dust samples. This monoclonal antibody was directed against mite antigens that were also reactive to immunoglobulin E antibody in all of 10 serum samples obtained from patients allergic to mites. Histological study using fluorescent antibody revealed that the monoclonal antibody was bound to the major part of the D. farinae mite body section including fecal matter and cuticles. The detection limit of the assay system was 0.17 microgram of soluble antigens of both mite species and the antigen amount corresponding to 0.5 mites per microplate well, whether in live or dead mites. This system did not react to antigens of Tyrophagus putrescentiae (Schrank) and Cheyletus malaccensis Oudemans. Slight inhibition of less than or equal to 21.3% was observed with nonspecific substances contained in house dust, such as wool, cotton, human dander, human hair, soil, and biscuit, but no direct ELISA reactions were obtained with any of these materials. In 49 house dust samples, ELISA was significantly correlated with the conventional microscopic observation method.
Magnetic resonance imaging of Achilles tendon ruptures (1989)

Preoperative magnetic resonance images of three acute Achilles tendon ruptures were correlated with the findings observed during surgical repair of the tendon. Specific comparisons were made regarding the condition (shredded, uniform, etc.) and orientation (antegrade, retrograde, etc.) of the torn fibers, and the width of the diastasis (with and without ankle flexion) between the ends of the tendon. Magnetic resonance imaging (MRI) accurately assessed all of these parameters.
Multi-stacked InAs/GaAs quantum dot structures and their photovoltaic characteristics (2003)

Multi-stacked InAs/GaAs quantum dot (QD) structures having various number of stacks were grown by molecular beam epitaxy (MBE) on n/sup +/-GaAs substrate. They were fabricated into Schottky barrier devices for photovoltaic characterizations. QDs at a slow growth rate of 0.01 ML/s were chosen for all samples in the whole experiment. Current-voltage (I-V) curves under AM1 solar simulator were measured. It was found that larger number of QD stacks gives more short-circuit current. Contribution to photovoltaic effects by multi-stacked InAs QDs in these matrix materials was confirmed by spectral response measurement, which shows that apart from the sharp drop of photo-response at the band edge of GaAs (/spl sim/0.9 /spl mu/m), spectral peak at 1.1-1.2 /spl mu/m, corresponding to quantized energy of InAs QDs, was observed from these multi-stacked QDs samples. Photocurrent measurement was conducted at 1.1 /spl mu/m wavelength by a band-pass filtered light source to see the correlation between photocurrent at this specific long wavelength and the QD stack numbers.

Potential Epidemic of Creutzfeldt–Jakob Disease from Human Growth Hormone Therapy (1985)

A DECADE after the demonstration that Creutzfeldt—Jakob disease could be accidentally transmitted from one person to another during brain or eye surgery,1 , 2 iatrogenic Creutzfeldt—Jakob disease has reappeared as a result of earlier therapy with human growth hormone, with the ominous possibility of a burgeoning epidemic.Within just a few months, three young adults in the United States have died from the disease, confirmed neuropathologically in two patients and clinically detected but unconfirmed in one3; an additional neuropathologically confirmed case has been identified in Great Britain.4 Salient data on these four cases are summarized in Table 1. (The details of both . . .
Analysis of linear predictive data such as speech by a class of single-layer connectionist models (1989)

Summary form only given: A class of single-layer connectionist models is analysed where the nonlinearity includes the logistic function commonly used in error back propagation analysis. It is shown that when the input data can be modelled by a linear predictive or autoregressive process, a solution exists for the weights which minimises the cost function and hence an output error cost function. This establishes the weight sets for single-layer connectionist models whose input data are linear predictive processes, such as speech. Comparisons are made with the equivalent error back propagation analysis and an alternative network structure is described. The method also suggests a form of connectionist vector quantisation (CVQ) for the analysis of speech. A number of experimental results are given. >
The lubrication of rollers (1958)

Abstract When lubricated rollers are run together they are separated by a hydrodynamically formed oil film. The thickness of this film has been measured by a capacitance method up to loads of 1000 Lb. per inch of face (1.76 x 103 dyn cm -1) for conditions of pure rolling and for conditions of rolling with sliding such as exist at the contacts of gear teeth. It has been found, at low loads, that the film thickness varies inversely with load and proportionately with speed, as simple hydrodynamic theory suggests, but that the actual thickness is approximately one-half of the theoretical thickness. At higher loads, of greater practical importance, the film thickness is shown to be of the order 1u (-4x10-5 in) which is greater than that predicted by simple theory. Experimental evidence is presented that this failure of the simple theory is due to the increased viscosity of the oil under pressure and to the deformation of the surfaces by the load. The film thickness, at practical loads, has been found to vary little with load, less than proportionately with speed but to vary greatly with the temperatures of the surfaces. Estimates of the temperature reached by the oil in its passage through the conjunction of the surfaces have been made from measurements of the electrical resistivity of the oil. This temperature, which depends upon load and the peripheral speeds and which may exceed 250° C, appears to have little influence upon the film thickness. From this it is argued that the film thickness is largely determined by the conditions, on the entry side of the conjunction, ahead of the region in which the viscous losses and heating of the oil become intense.
THE EUROPEAN TRAIN CONTROL SYSTEM IN THALES SIGNALLING SOLUTIONS (2008)

Rail signalling solutions designed by Thales integrate conventional signalling technology with advanced systems based on the European Train Control System (ETCS) standard. The degree of integration is classified according to the different levels defined in this standard. Level 1 is still based on light signals, but Eurobalises increasingly replace national intermittent train protection systems. Thales has provided equipment for several national level 1 projects. In level 2 a continuous train supervision is achieved. The Radio Block Centre (RBC) developed by Thales is responsible for the centralised protection of train movements for lines that are operated with level 2 equipment. It receives a train's position from its onboard unit and the trackside signalling information from the interlocking system. With this information and with the properties of the underlying track map it generates the movement authority for the train. In various European projects the interoperability of the Thales RBC with signalling equipment of other manufacturers has been proven.
PEITC reverse multi‐drug resistance of human gastric cancer SGC7901/DDP cell line (2013)

Gastric cancer is one of the leading causes of cancer death in the world and nearly all patients who respond initially to cisplatin later develop drug resistance, indicating multi-drug resistance is an essential aspect of the failure of treatment. Phenethyl isothiocyanate (PEITC) has been implicated in inhibiting metastasis of several types of human cancer. However, the effect and potential mechanism of PEITC reversed multi-drug resistance of human gastric cancer is not fully clear. We have identified the role of PEITC in multi-drug resistance reversal of human gastric cancer SGC7901/DDP cell line. PEITC inhibited cisplatin-resistant human SGC7901/DDP cell growth in a dose-dependent manner, causing increased apoptosis, ROS generation, glutathione depletion, accumulation of Rhodamine-123, decreased expression of P-glycoprotein and cell cycle arrest. mRNA and protein expression of the multi-drug resistance gene (MDR1), multi-drug resistance-associated protein (MRP1), excision repair cross-complementing gene 1 (ERCC1), survivin, and Mad2 was decreased, and phosphorylation of Akt and transcriptional activation of NF-κB were suppressed. PEITC may be useful as the therapeutic strategy for overcoming multi-drug resistance through suppressing the PI3K-Akt pathway in human gastric cancer.
Pitavastatin improves glycated hemoglobin in patients with poorly controlled type 2 diabetes (2016)

Pitavastatin decreases HbA1c in patients with type 2 diabetes with a higher baseline HbA1c level. The benefit on HbA1c was also observed in patients with previous use of atorvastatin.
Silicon/Metal Hybrid Nanosystem with Tailored Magnetic Properties in Two Characteristic Field Regions (2008)

Electrodeposition of ferromagnetic metal-nanostructures into a porous silicon (PS) matrix merges the electronic properties of a semiconductor and the ferromagnetic ones of the precipitated metal on one material level. The deposition is performed using a metal-salt solution as electrolyte and an applied pulsed current under cathodic conditions. The metal precipitation within a PS-template exhibiting unconnected mesopores with aspect ratios of about 1000 leads to nanostructures with a maximum elongation of a few microns (aspect ratio 100). The achieved hybrid system exhibits magnetic characteristics which drastically differ from the corresponding bulk materials. Magnetization measurements of this material show two characteristics, one at magnetic fields below the saturation magnetization MS of the deposited metals due to the spin-magnetism (e.g. MS (Ni)=0.62 T, MS (Co)=1.82 T) and another one at higher fields above MS which is assigned to a novel, recently intensively investigated magnetic contribution likely caused by spin-orbit interaction.

Person Re-identification by Deep Learning Multi-scale Representations (2017)

Existing person re-identification (re-id) methods depend mostly on single-scale appearance information. This not only ignores the potentially useful explicit information of other different scales, but also loses the chance of mining the implicit correlated complementary advantages across scales. In this work, we demonstrate the benefits of learning multi-scale person appearance features using Convolutional Neural Networks (CNN) by aiming to jointly learn discriminative scale-specific features and maximise multiscale feature fusion selections in image pyramid inputs. Specifically, we formulate a novel Deep Pyramid Feature Learning (DPFL) CNN architecture for multi-scale appearance feature fusion optimised simultaneously by concurrent per-scale re-id losses and interactive cross-scale consensus regularisation in a closed-loop design. Extensive comparative evaluations demonstrate the re-id advantages of the proposed DPFL model over a wide range of state-of-the-art re-id methods on three benchmarks Market-1501, CUHK03, and DukeMTMC-reID.

Secular and Seasonal Trends of Neospora Abortion in California Dairy Cows (1995)

This study was undertaken to determine if the proportion of dairy cow abortions attributable to Neospora sp. infection increased or occurred in a seasonal cycle during a 6-yr period. Abortions caused by Neospora sp. were tallied for all fetuses submitted to the Tulare branch of the California Veterinary Diagnostic Laboratory between January 1985 and December 1990. Regression analysis of 221 cases of Neospora among 762 fetuses submitted showed a weak increasing secular trend (P = 0.053, r2 = 0.05), with predicted monthly proportions at the beginning and end of the 6 yr of 0.16 and 0.33, respectively. Using a Kolmogorov-Smirnov-type statistic, comparison of the 12-mo distribution of Neospora sp. cases and a hypothetical distribution of cows at risk of aborting found about 16% of variation in cases was attributable to season (P < 0.01). More cases were found in winter than in summer and early fall. Results indicate that Neospora sp. abortion in California dairy cows is not new or recently emerging and that seasonally related factors influence some of the risk of abortion. Results suggest that Neospora sp. has contributed to the high dairy cow abortion rate for many years, and that seasonally varying exposures may predispose to transmission or recrudescence of infection.
Weight adaptation and oscillatory correlation for image segmentation (2000)

We propose a method for image segmentation based on a neural oscillator network. Unlike previous methods, weight adaptation is adopted during segmentation to remove noise and preserve significant discontinuities in an image. Moreover, a logarithmic grouping rule is proposed to facilitate grouping of oscillators representing pixels with coherent properties. We show that weight adaptation plays the roles of noise removal and feature preservation. In particular, our weight adaptation scheme is insensitive to termination time and the resulting dynamic weights in a wide range of iterations lead to the same segmentation results. A computer algorithm derived from oscillatory dynamics is applied to synthetic and real images and simulation results show that the algorithm yields favorable segmentation results in comparison with other recent algorithms. In addition, the weight adaptation scheme can be directly transformed to a novel feature-preserving smoothing procedure. We also demonstrate that our nonlinear smoothing algorithm achieves good results for various kinds of images.
Catheter-induced lesions of the right side of the heart. A one-year prospective study of 141 autopsies (1985)

We examined prospectively for one year the hearts from 141 consecutive autopsy cases in which a central catheter was present at the time of death. Three deaths were attributable to catheter use, two to perforation. Furthermore, mural thrombi were present in 33 (33%) of 99 patients with pulmonary arterial catheters and in 12 (29%) of 42 patients with central venous catheters. The incidence of pulmonary emboli or bacteremia was no greater in patients with thrombi than in those without. The use of central catheters may thus be complicated by perforation or the development of mural thrombi. Although the thrombi may embolize or may become infected, the incidence and clinical significance appear to be low. The incidence of catheter-related deaths in our autopsy population does not necessarily reflect the incidence in a population of living patients. (<i>JAMA</i>1985;253:791-795)
Introduction (2011)

Xenarchus of Seleucia is best known for his vigorous criticism of Aristotle's thesis that the celestial bodies are made of a special simple body, unique to them: the fifth substance, also known as the fifth body, fifth element, quinta essentia, or aither. However, his activity was not confined to the study of physics, let alone celestial physics. Although the surviving evidence is slim, and at times frustratingly so, there is no doubt that Xenarchus was concerned with issues of ethics and psychology as well as of physics. In this book I consider all areas of his activity in order to offer as complete a picture of Xenarchus as our sources permit.
A comparison of gravimetric techniques for measuring subsurface void signals (2001)

To demonstrate the potential of gravity gradiometry in the detection of underground structures or voids, an experiment was carried out at an underground missile launch facility at Vandenberg Air Force Base, California. Gravity data were collected using a LaCoste-Romberg Model G gravimeter and gravity gradient measurements were made using a vertical spin-axis Lockheed Martin developed arms control verification gravity gradiometer. After performing all necessary corrections, the data were compared to modelled signatures of the launch facility. Peak gravity and gravity gradient anomalies of approximately -75 µGal (1 µGal = 10-8 m s-1) and 30 E (1 E = 10-9 s-2) respectively were measured over the centreline of the largest capsule. The presence of the buried launch facility was apparent in both the observed gravity and gravity gradient data. The gravity gradients were unambiguous in resolving the underground facility's signature and thus revealing its location. In contrast, identifying the launch complex solely from the gravity anomaly data would have proven difficult due to a strong regional trend across the target area.}

A robust eye localization method for low quality face images (2011)

Eye localization is an important part in face recognition system, because its precision closely affects the performance of face recognition. Although various methods have already achieved high precision on the face images with high quality, their precision will drop on low quality images. In this paper, we propose a robust eye localization method for low quality face images to improve the eye detection rate and localization precision. First, we propose a probabilistic cascade (P-Cascade) framework, in which we reformulate the traditional cascade classifier in a probabilistic way. The P-Cascade can give chance to each image patch contributing to the final result, regardless the patch is accepted or rejected by the cascade. Second, we propose two extensions to further improve the robustness and precision in the P-Cascade framework. There are: (1) extending feature set, and (2) stacking two classifiers in multiple scales. Extensive experiments on JAFFE, BioID, LFW and a self-collected video surveillance database show that our method is comparable to state-of-the-art methods on high quality images and can work well on low quality images. This work supplies a solid base for face recognition applications under unconstrained or surveillance environments.
Cryosurgery for common skin conditions. (2004)

Cryosurgery is a highly effective treatment for a broad range of benign skin problems. With appropriate instruction and supervised experience, family physicians can master the technique quickly. Cryosurgery is best suited for use in patients with light skin and for treatment of lesions in most non-hair-bearing areas of the body. Spray methods include the timed spot freeze technique, the rotary or spiral pattern, and the paintbrush method. Benign skin lesions that are suitable for freezing include actinic keratosis, solar lentigo, seborrheic keratosis, viral wart, molluscum contagiosum, and dermatofibroma. Cryosurgery requires little time and fits easily into the physician's office schedule. Advantages of this treatment include a short preparation time, low risk of infection, and minimal wound care. In addition, cryosurgery requires no expensive supplies or injectable anesthesia, and the patient does not have to return for suture removal. Potential side effects include bleeding, blister formation, headache, hair loss, and hypopigmentation, but rarely scarring. Skin lesions often can be treated in a single session, although some require several treatments.
