A compact and robust magnetic label  detector for biomedical assays  is implemented in 0.18-μm  CMOS.    No external magnet, reference sensor or baseline calibration is required.  Detection relies on the magnetic relaxation signature of a microbead label for improved tolerance to environmental variations and relaxed dynamic range requirement.

An equally important consideration is the computational efficiency in performing infer-ence in the high-dimensional setting. This high-dimensional structure precludes the usualglobal assumptions—namely, strong convexity and smoothness conditions—that underlie much of classical optimization analysis.

The matrix powers kernel, used in communication-avoiding Krylov subspace methods, requires runtime auto-tuning for best performance. We demonstrate how the SEJITS (Selective Embedded Just-In-Time Specialization) approach can be used to deliver a high-performance and performance-portable implementation of the matrix powers kernel to application authors, while separating their high-level concerns from those of auto-tuner implementers involving low-level optimizations. The benefits of delivering this kernel in the form of a specializer, rather than a traditional library, are discussed. Performance of the matrix powers kernel specializer is evaluated in the context of a communication-avoiding conjugate gradient (CA-CG) solver, which compares favorably to traditional CG.

This thesis demonstratesthe role of structured codes in several network and MIMO settings. In MIMO channels,structured codes can be used to improve receiver design.By using lattice codes in the physical layer and networkcodes in the network layer, the proposed scheme achieves the optimal distortion to within aconstant factor. Finally, structured codes can be used to e?ciently transmit channel state information when global channel state information is absent in networks.

Creating high-quality  tasks   today requires significant expertise,  which prevents novice users from receiving reasonable results without iterating multiple times over their description.Although expert tasks still perform comparably better, we show that novice users can receive higher quality results when being supported by a guided task specification interface.

For a complementary similarity analysis approach, we propose DStruct, a tool for detecting similar Android applications based on their directory structures. DStruct provides another method for performing similarity analysis to address problems in Android security, including determining if applications are pirated or contain instances of known malware.

Advances in research and technology are happening now more than ever in the biotechnology industry. Efficient methods for biological processes and better detection and treatment methods are constantly being sought by researchers. Collaboration among diffe rent fields of science and technology has brought us one step closer towards achieving this goal in this work. One such technology that has the capability of providing efficient methods and processes for biology is printed electronics. Printed electronics is an attractive paradigm for realization of biological microfluidic systems. The large area of these systems makes printing valuable from a cost perspective. Furthermore, since printing allows for easy integration of disparate materials on the same substrate through spatially-specific deposition, printed electronics is particularly useful for integration of diverse biological microfluidic functionality on the same substrate..This work has thus successfully revealed the potential of printed electronics in real-world biological applications and has also paved the way for exciting future research areas for this technology.
