摘要:
A ball striking device, such as a golf club head, includes a face having a ball striking surface configured for striking a ball and a body connected to the face and extending rearwardly from the face. The body has an impact-influencing structure positioned adjacent at least one peripheral edge of the face. A majority of a force generated by impact with a ball is absorbed by the impact-influencing structure, and a majority of a response force generated by the head upon impact with the ball is generated by the impact-influencing structure. The face may have increased stiffness as compared to existing faces, and may include a stiffening structure to create the increased stiffness. In one embodiment, the face may have a stiffness proximate the geometric center that is from about 4,600-5,600 lb-in2.

Certain examples provide systems and methods for analysis and graphical visualization of healthcare services data. Certain examples provide a healthcare services analysis and visualization system. The system includes a data store to store data related to healthcare services provided in at least one geographic region. The system also includes a processor to retrieve and sort data from the data store based on one or more criteria, analyze the sorted data, and transform the sorted data into a geographical map representation of the healthcare services data. The system includes a user interface to display the geographical map representation of the healthcare services data and facilitate user review and interaction with the geographical map representation and the underlying healthcare services data.

A well system is provided and configured for local and/or global control of a well. The well system may comprise one or more controllable downhole devices. Each of the downhole devices may include a telemetry module, an energy module configured to at least power an actuator, a controller communicably coupled to the telemetry module and one or more sensors, and a controllable component coupled to the actuator. The well system may further include a surface controller comprising a desired state input device configured to accept a desired state and then provide the desired state to the controller via the telemetry module. The controller may compare the desired state to an actual state determined by a sensor and instruct the actuator to adjust the controllable component such that the actual state approaches the desired state. The downhole device may operate autonomously after the initial setting of the desired state.

The mechanism of the UV light-induced reaction between the indole moiety of tryptophan and chloroform, and the structure of the modified tryptophan and polypeptides including such modified tryptophan residues. The excited indole moiety, which is formed upon UV light irradiation, emits a solvated electron which initiates a series of events that yield fluorescent derivatives that have CHO group covalently bound to the indole moiety. These derivatives are herein referred to as formyltryptophan, and are relatively stable. Similar reactions are observed when 5-hydroxytryptophan, 5-fluorotryptophan, or N-methylindolacetate are used in place of tryptophan, or when other haloalkanes, such as trichloracetic acid, trichlorethanol, trichlorethane, bromoform, and iodoactetate are used in place of chloroform. The derivatives can be used in a variety of applications in fluorescence spectroscopy, and for nuclear magnetic resonance, X-ray crystallography, infra-red spectroscopy, circular dicroism and mass spectroscopy. Additionally, the UV light-induced reaction between the indole moiety of tryptophan and haloalkanes can be used to prepare derivatives of tryptophan for chemical cross-linking studies of proteins and peptides.

A flexible mounting base to hold a sensor at an infusion site, the sensor being a removable in vivo sensor for monitoring analyte concentration level in a patient, such as blood glucose (BG) level. The mounting base comprises a flexible adhesive that anchors the flexible sensor set at an infusion site to provide stability for the sensor set in a convenient and comfortable manner. Placement of the mounting base onto the patient's skin causes the insertion needle to pierce the skin for transcutaneous placement of the cannula with the sensor therein. The insertion needle can then be withdrawn to leave the cannula and sensor at the selected insertion position, with the distal segment of the sensor being exposed to patient extracellular fluid via apertures formed in the cannula.

摘要:
An electrical current is passed through a thermistor to raise its temperature above the temperature of oil flowing in pulses past the thermistor. A change is measured in the temperature of the thermistor occurring with respect to one or more of the pulses. A level of oil flow is determined corresponding to the measured change in temperature. A signal is issued based on the determined flow level.
