A system and method lets a user create or import ontologies and create databases and related application software. These databases can be specially tuned to suit a particular need, and each comes with the same error-detection rules to keep the data clean. Such databases may be searched based on meaning, rather than on words-that-begin-with-something. And multiple databases, if generated from the same basic ontology can communicate with each other without any additional effort. Ontology management and generation tools enable enterprises to create databases that use ontologies to improve data integration, maintainability, quality, and flexibility. Only the relevant aspects of the ontology are targeted, extracting out a sub-model that has the power of the full ontology restricted to objects of interest for the application domain. To increase performance and add desired database characteristics, this sub-model is translated into a database system. Java-based object-oriented and relational application program interfaces (APIs) are then generated from this translation, providing application developers with an API that exactly reflects the entity types and relations (classes and methods) that are represented by the database. This generation approach essentially turns the ontology into a set of integrated and efficient databases.

One embodiment of the present invention is a system and method of encouraging customers to review purchased items. Customers are provided with review requests a predetermined amount of time after the customer has purchased an item or had the item delivered. The predetermined amount of time is related to an estimated time it will take the customer to evaluate the item. The reviews may include textual reviews that are presented to other customers and/or item ratings that are used to generate personal recommendations.

Embodiments of the invention provide novel systems, software and methods for gathering information about online entities and for identifying, evaluating and scoring such entities. Merely by way of example, the trustworthiness of an online entity, such as a domain, can be evaluated based information known about other online entities (e.g., the owner of the domain, other domains) associated with that domain. In an aspect of the invention, for example, publicly-available data (and, in some cases, other data) can be obtained and correlated to reveal previously-unknown associations between various online entities, despite, in some cases, the attempts of those entities to obscure such associations. This can facilitate the evaluation of such entities. For instance, if a new domain is registered, there generally is little basis on which to evaluate the trustworthiness of that domain (other than facially-apparent characteristics, such as the domain name itself), since it has not yet begun operating. By ascertaining the domain's association with other online entities, however, information known about the reputation and/or behavior of those entities can be used to inform an evaluation of the domain.

Systems and methods for noninvasive assessment of cardiac tissue properties and cardiac parameters using ultrasound techniques are disclosed. Determinations of myocardial tissue stiffness, tension, strain, strain rate, and the like, may be used to assess myocardial contractility, myocardial ischemia and infarction, ventricular filling and atrial pressures, and diastolic functions. Non-invasive systems in which acoustic techniques, such as ultrasound, are employed to acquire data relating to intrinsic tissue displacements are disclosed. Non-invasive systems in which ultrasound techniques are used to acoustically stimulate or palpate target cardiac tissue, or induce a response at a cardiac tissue site that relates to cardiac tissue properties and/or cardiac parameters are also disclosed.

A flexible medical intubation instrument provided for placement into an animal or human patient comprises a catheter with at least a pair of longitudinally extending lumens or channels including a sensor and/or actuator channel and a working channel. In the sensor/actuator channel is provided a fixed or slideably removable sensor cable having a sensor for sensing a characteristic or condition including any of the following: a visual sensor for optical viewing, a chemical sensor, a pH sensor, a pressure sensor, an infection sensor, an audio sensor, or a temperature sensor. The sensors are coupled by the sensor/actuator cable through light transmission, electric current, or radio transmission to a viewing instrument or other output device such as a meter or video screen for displaying the condition that is sensed within the body of the patient while the flexibility of the composite structure comprising the catheter and cable enable the entire instrument to flex laterally as it moves through curved passages or around obstructions during insertion or removal. While making observations through the sensor channel, the working channel simultaneously functions as a drain or an irrigation duct, a feeding tube, or to provide a passage for the insertion of one or a succession of surgical devices such that the catheter serves as a protective artificial tract or liner as surgical devices are inserted and removed through it in succession so as to minimize tissue trauma, infection, and pain experienced by the patient. The instrument can be used in urology, as well as a visually directed nasogastric tube, as a visually directed external gastrostomy tube, or as a visually directed internal gastric tube or percutaneous endoscopic gastrostomy tube and in other applications.

Some embodiments of this disclosure relates to systems and methods for imaging a patient's vasculature. For example, near infrared (NIR) light can be used to illuminate a target area and light that is reflected or scattered from the target area can be used for generate an image of the target area. In some embodiments, the system can be configured such that the image shows the presence, absence, or extent of infiltration or extravasation in the target area. The system can be configured to document that presence, absence, or extend of infiltration or extravasation at an infusion site. In some embodiments, an imaging system can be mounted onto a patient so that the imaging system can monitor an infusion site, and the imaging system can be configured to automatically detect the presence of infiltration or extravasation.

Techniques, hardware, and software are provided for quantification of extensional features of structures of an imaged subject from image data representing a two-dimensional or three-dimensional image. In one embodiment, stenosis in a blood vessel may be quantified from volumetric image data of the blood vessel. A profile from a selected family of profiles is fit to selected image data. An estimate of cross sectional area of the blood vessel is generated based on the fit profile. Area values may be generated along a longitudinal axis of the vessel, and a one-dimensional profile fit to the generated area values. An objective quantification of stenosis in the vessel may be obtained from the area profile. In some cases, volumetric image data representing the imaged structure may be reformatted to facilitate the quantification, when the structural feature varies along a curvilinear axis. A mask is generated for the structural feature to be quantified based on the volumetric image data. A curve representing the curvilinear axis is determined from the mask by center-finding computations, such as moment calculations, and curve fitting. Image data are generated for oblique cuts at corresponding selected orientations with respect to the curvilinear axis, based on the curve and the volumetric image data. The oblique cuts may be used for suitable further processing, such as image display or quantification.

Methods for classifying plants by remote sensing and image analysis technology are presented. These methods are useful for evaluating plants and for selecting plants for a plant breeding program which has as its goal to selectively alter phenotype. The methods combine the newer techniques of remote sensing technology to obtain indirect correlates of the traits of interest, with classical pedigree breeding strategies. Thermal and infrared reflectance measures of plant canopies are examples of energy values measured by remote sensing, used to indirectly predict the selected traits.

An implantable medical device and method are provided for assessing autonomic tone and risk factors associated with arrhythmias and, based on this assessment, an early recurrence of ventricular tachycardia or ventricular fibrillation is predicted. Specifically, changes in R—R interval, heart rate variability, patient activity, and myocardial ischemia are measured prior to and after a detected an arrhythmia episode. A recurrence score is calculated as a weighted sum of measured parameters and compared to a prediction criterion. The prediction criterion may be a preset threshold score or an individualized episode template based on previously calculated recurrence scores associated with recurring episodes. Stored parameters and episode-related data may be downloaded for offline analyses for optimizing prediction criteria and monitoring patient status.
