Abstract: Techniques for optimal device position for wireless communication are described, and may be implemented via a mobile device to identify an orientation in which to place a mobile device to achieve optimum wireless signal. Generally, the described techniques enable the mobile device to be dynamically calibrated for wireless communication by identifying signal attributes at multiple different device positions, and enabling the mobile device to be placed at a position that exhibits optimum wireless signal. Further, wireless tasks to be performed on a mobile device can be placed into a task queue and executed when the mobile device is detected at a location and/or position that exhibits optimum wireless signal.

Abstract: A linker peptide for constructing a fusion protein. The linker peptide comprises a flexible peptide and a rigid peptide. The flexible peptide consists of one or more flexible units. The rigid peptide consists of one or more rigid units. The flexible unit comprises two or more amino acid residues selected from Gly, Ser, Ala, and Thr. The rigid unit comprises a human chorionic gonadotropin ?-subunit carboxy-terminal peptide (CTP) bearing a plurality of glycosylation sites. The linker peptide can more effectively eliminate mutual steric hindrance of two fusion molecules, decreasing a reduction/loss of polymerization or activity resulting from improper folding of an active protein or a conformational change. On the other hand, the negatively charged, highly sialylated CTP can resist renal clearance, further prolonging a half-life of a fused molecule and enhancing bioavailability of a fused protein.

For instance, the described techniques enable a wireless device to be calibrated for wireless communication by identifying different obstruction states of a wireless device that correspond to ways that the wireless device is held (e.g., grasped) by a user in different scenarios.

Further, calibration can take into specific processes (e.g., applications) and specific users to calibrate an optimize wireless performance based on ways in which a user typically interacts with a process.
