Apparatus and methods for deactivating bronchial nerves and smooth muscle extending along a bronchial branch of a mammalian subject to treat asthma and related conditions. An electromechanical transducer (11) is inserted into the bronchus as, for example, by advancing the distal end of a catheter (10) bearing the transducer into the bronchial section to be treated. The electromechanical transducer emits unfocused mechanical vibratory energy of one or more ultrasonic frequencies so as to heat tissues throughout a relatively large target region (13) as, for example, at least about 1 cm³ encompassing the bronchus to a temperature sufficient to inactivate nerves but insufficient to cause rapid ablation or necrosis of organic tissues. The treatment can be performed without locating or focusing on individual bronchial nerves.

Pseudo-random numbers (PRNs) generated by a PRN generator are mapped to predefined number ranges or target ranges. The target range may be smaller or larger than the range of the PRN generator. Mapping to a smaller target range may include generating PRNs (e.g., integers) from a particular bit-input stream (e.g., 32-bit) having a uniform distribution across the range of numbers; selecting an optimal subset of the generated PRNs to map; and mapping the selected PRNs to a corresponding number in a target range such that the mapped numbers are uniformly distributed across the target range. Mapping to a larger target range may include generating uniformly distributed PRNs; applying a generation function to the PRNs to generate uniformly distributed packed numbers; and applying a mapping function to map selected packed numbers to the target range such that the mapped numbers are uniformly distributed.

Techniques for aiding user input with a graphical user interface (GUI) are disclosed. A target object among various command regions of the GUI is predicted, e.g., substantially before the cursor reaches any of the regions. The command region corresponding to the predicted target object is enlarged to facilitate user selection of the predicted target object. Enlarging the predicted target object may cause the target object to overlap and/or occlude nearby command regions. After a first target object is predicted, the prediction may be changed based on updated cursor movements. By using predictive target enlargement, users are given early visual feedback about the target, and are given a larger target to acquire, thereby allowing them to be faster and less precise (their mouse direction can wander) yet still acquire their desired result.

A method of forming a sputtering target assembly is described that involves explosively bonding a target grade plate and a backing plate member to form a bonded preform having dimensions such that a large target or several target assemblies can be obtained. The method includes optionally partitioning the bonded preform into a plurality of sputtering target assemblies. An interlayer can optionally be disposed between the target grade plate and the backing plate member before bonding. A bond quality test sample can be produced by the method. The sputtering target assemblies, the bonded preform, and the bond quality test sample are further described.

• • (a) a non-magnetic substrate having a surface; and
  • (b) a layer stack formed over the substrate surface, comprising in overlying sequence from the substrate surface:
    • (i) a magnetically soft underlayer;
    • (ii) an interlayer structure for crystallographically orienting a layer of a perpendicular magnetic recording material formed thereon; and
    • (iii) at least one crystallographically oriented magnetically hard perpendicular recording layer;
  • wherein the magnetically soft underlayer is sputter-deposited at a sufficiently large target-to-substrate spacing and at a sufficiently low gas pressure selected to provide the underlayer with a smooth surface having a low average surface roughness Ra below about 0.3 nm, as measured by Atomic Force Microscopy (AFM).

An apparatus for slitting a running paperboard web includes a thin high speed rotary slitting blade that is plunged through the moving web and into a slot between a pair of anvil rollers supporting the web on the opposite side. Because the slitting blade and the anvil rollers are vertically separated and pre-positioned before order change, an adjustment apparatus is provided to spread the anvil rollers axially apart to provide an open gap with a large target for blade edge when it is plunged through the web and into the slot. The anvil rollers are then closed against the opposite faces of the blade for running operation. Preferably, the anvil rollers are mounted on brackets hinged together below the rollers to move the opposite upper edges of the rollers between the opened and closed position in the manner of a clam shell. The anvil roller assembly is also adjustable in the machine direction to compensate for reduction in rotary slitting blade diameter with blade wear.

A pattern from a patterning device is applied to a substrate by a lithographic apparatus. The applied pattern includes product features and metrology targets. The metrology targets include large targets and small targets which are for measuring overlay. Some of the smaller targets are distributed at locations between the larger targets, while other small targets are placed at the same locations as a large target. By comparing values measured using a small target and large target at the same location, parameter values measured using all the small targets can be corrected for better accuracy. The large targets can be located primarily within scribe lanes while the small targets are distributed within product areas.

The present invention provides a method and apparatus for detecting the noncovalent binding of a potential ligand (such as a drug candidate) to a target, e.g. a biochemical macromolecule such as a protein. The method is based on the Taylor dispersion of an initially sharp boundary between a carrier solution, and an analyte solution that contains the potential ligand(s) and the target. Dispersion profiles of one or more potential ligands are monitored by mass spectrometry at the exit of the laminar flow tube. Potential ligands will usually be relatively small molecules that have large diffusion coefficients. In the absence of any noncovalent interactions in solution, very steep dispersion profiles are expected for these potential ligands. However, a ligand that binds to a large target in solution, will show an apparent diffusion coefficient that is significantly reduced, thus resulting in a more extended dispersion profile. Noncovalent binding can therefore be detected by monitoring dispersion profiles of potential ligands in the presence and in the absence of the target. In contrast to other mass spectrometry-based methods for detecting noncovalent interactions, this method does not rely on the preservation of specific noncovalent interactions in the gas phase. This method has an excellent sensitivity and selectivity, therefore it can be used for testing multiple potential ligands simultaneously. The method is therefore useful for the high throughput screening of compound libraries.

The invention discloses a traffic sign detection method in automatic driving based on a YOLOv3 network, and belongs to the field of traffic sign detection. The method solves the problems that an existing YOLOv3 network target detection algorithm is not high in detection precision and the detection speed cannot meet the real-time requirement. According to the invention, an improved loss function isprovided, so that the influence of a large target error on a small target detection effect is reduced, and the detection accuracy of a small-size target is improved. An improved activation function is provided, a negative value is reserved, meanwhile, changes and information propagated to the next layer are reduced, and the robustness of the algorithm to noise is enhanced. The real frames in thetraffic sign data set are clustered by using a K-means algorithm to realize the pre-fetching of a target frame position and accelerate convergence of the network. The detection precision mAP of the traffic sign detection model on a test set reaches 92.88%, the detection speed reaches 35FPS, and the requirement for real-time performance is completely met. The method can be applied to the field of traffic sign detection.

Method and apparatus for performing automatic implied attribution is described, and in particular implied attribution in connection with a campaign. The campaign can be a marketing campaign in which actions (offer cells) are aimed at a contact group and behaviors are monitored within a defined evaluation period. By this method, the behaviors of the contact group can be attributed to the offer cells The method allows the monitoring of multiple behaviors for any number of offer cells for any number of contact groups. Contact groups can be obtained by any query process. The behaviors of a larger target group can also be implied where a link can be established between the contact group and the target group. Also described is a system for performing implied attribution, where the system can be software running on a general purpose computer.

A method is disclosed for the direct synthesis of double stranded DNA molecules of a variety of sizes and with any desired sequence. The DNA molecule to be synthesis is logically broken up into smaller overlapping DNA segments. A maskless microarray synthesizer is used to make a DNA microarray on a substrate in which each element or feature of the array is populated by DNA of a one of the overlapping DNA segments. The complement of each segment is also made in the microarray. The DNA segments are released from the substrate and held under conditions favoring hybridization of DNA, under which conditions the segments will hybridize to form duplexes. The duplexes are then separated using a DNA binding agent which binds to improperly formed DNA helixes to remove errors from the set of DNA molecules. The segments can then be hybridized to each other to assemble the larger target DNA sequence.
