A method for diagnosing potential faults reflected in operational data for a turbine engine includes the steps of generating a diagnostic pattern for the operational data and comparing the diagnostic pattern with a plurality of historical patterns, to thereby identify one or more likely potential faults reflected in the operational data. The diagnostic pattern comprises a plurality of scalars. Each scalar represents an arithmetic relationship between values of the operational data and values predicted by a baseline thermodynamic model. Each historical pattern is linked to one or more specific faults.

Flanking sequences may optionally be attached at one or both the carboxy-terminal and amino-terminal ends of the peptide in covalent association with adjacent framework regions. Compositions containing such antibodies or fragments thereof are useful in therapeutic and diagnostic modalities.

System, method and apparatus for carrying out isometric exercises for either diagnostic purposes or therapeutic purposes. When employed in a diagnostic mode, the instrument is programmed to carry out standardized diagnostic regimens and during such regimens provides both visual and aural cues, carries out mathematical computations of force values and provides recordation of diagnostic data in archival memory. When employed in a therapeutic mode the apparatus may only be programmed within mandated therapeutic parameter limitations. During therapeutic trials, the user is visually and aurally cued throughout the test sequence and the therapeutic data evolved during the regimen is recorded and recoverable from archival memory.

The invention discloses a diagnosis marker suitable for an early-stage esophageal squamous cell cancer diagnosis and a screening method of the diagnosis marker. Twenty five kinds of serum metabolic markers and ten relevant metabolic pathways are discovered; through the combination of the twenty five kinds of serum metabolic markers, the diagnosis marker used for an esophagus cancer diagnosis can be obtained. The screening method of the diagnosis marker has high operability; the diagnosis marker can be used for building a diagnosis model; the diagnosis model has the advantages of good effect, high sensitivity and good specificity, is suitable for a late-stage esophagus cancer diagnosis and is also suitable for the early-stage esophagus cancer diagnosis. The diagnosis model built by adopting the diagnosis marker provided by the invention has the advantages that the diagnosis can be realized only through blood sampling; the noninvasive effect is achieved; the cost is low; the modern internal invasive diagnosis mode can be well replaced; the pain of a patient is greatly reduced; in addition, the diagnosis speed is high; convenience is realized; the required time is short; the work efficiency is improved; the early discovery and early treatment of an esophagus cancer can be favorably realized; good clinic use and popularization value is realized.

Antibodies or fragments thereof having at least two CDR regions replaced or fused with biologically active peptides are described. Compositions containing such antibodies or fragments thereof are useful in therapeutic and diagnostic modalities.

A method to initiate a remote diagnostic mode in a network terminal includes determining whether a received signal corresponds to a command to initiate a remote diagnostic mode, and setting the network terminal in a remote diagnostic mode in accordance with the result of the determining. An authentication procedure may be performed prior to setting the network terminal in the remote diagnostic mode, for increased security.

The invention discloses a method for pylorus and ileocecal valve positioning through wireless capsule endoscope images. When a wireless capsule endoscope is used for examination, the starting point and the stopping point of the small intestine are accurately found so that the workload of a doctor for viewing the images can be reduced, and missed diagnosis is reduced. According to the method, a deep learning thought serves as a technical core, a transfer learning strategy is also used, and a convolution neural network algorithm in a deep learning model is used for building an area image classifier; features of the wireless capsule endoscope images are obtained through automatic learning by means of training of the model, and then an area image identification result sequence is analyzed through an area positioning algorithm, so that pylorus and ileocecal valve positioning in the wireless capsule endoscope images is achieved. The method makes up for the blank of an existing capsule endoscope in the field of intelligent identification and accurate positioning, the working intensity of a doctor is greatly reduced, the working efficiency and the diagnosis rate are improved, the practicalvalue of the capsule endoscope in the clinical diagnosis of digestive tract diseases is further promoted, and a more efficient and more standard diagnosis mode is formed.

A system for diagnosis and treatment of breathing disorders in a patient, comprises a flow generator supplying an air flow to an airway of a patient via a flow path, a venting arrangement moveable between (i) a closed position in which the flow path is substantially sealed between the flow generator and the patient's airway and (ii) an open position in which the flow path is open to an ambient atmosphere, a sensor detecting data corresponding to flow through the patient's airway, and a processing arrangement controlling operation of the venting arrangement and the flow generator, wherein, in a diagnostic mode, the processing arrangement maintains the venting arrangement in the open position and in a therapeutic mode, the processing arrangement maintains the venting arrangement in the closed position and controls the flow generator to supply to the patient's airway via the flow path a calculated therapeutic pressure.

As medical imaging becomes more affordable, and the diversity of diagnostic modalities and therapeutic treatments increase, the amount of data being stored increases, and the problem becomes even more critical. One approach to improve retrieval efficiency of images is to employ semantics to establish a defined set of search and classification terms. However, such semantic systems still require the user to make a selection of the most appropriate term or terms to classify a report or image, and the accuracy of the results are thus dependent on the skill and knowledge of the classifier. According to a first aspect of the invention, a retriever is provided for retrieving a medical image having a searchable attribute, the retriever being configured to interface with a semantic database and an image database, and wherein the searchable attribute is determined by segmenting the medical image, using the anatomical model.

The application embodiment provides a vehicle diagnosis method, a diagnosis terminal and a diagnosis box; the vehicle diagnosis method comprises the following steps: the diagnosis terminal determinesa diagnosis type to which a to-be-diagnosed vehicle belongs according to a received diagnosis command, and further determines a target diagnosis mode of the needed diagnosis box according to the diagnosis type when the to-be-diagnosed vehicle is diagnosed; the diagnosis terminal obtains the present diagnosis mode of the diagnosis box; if said two diagnosis modes are different, the diagnosis terminal sends a diagnosis mode switching command to the diagnosis box so as to remind the diagnosis box to switch the target diagnosis mode, thus enabling the diagnosis terminal to diagnose the to-be-diagnosed vehicle via the diagnosis box working in the target diagnosis mode. The method integrates the diagnosis box that supports new model diagnosis standards and old model diagnosis standards with diagnosis software, thus automatically selecting a proper diagnosis mode according to the to-be-diagnosed vehicle model, preventing frequently switching of the diagnosis modes and diagnosis software of the diagnosis box, and improving the diagnosis efficiency.
