Distributed algorithms for solving coupled semidefinite programs (SDPs) commonly require many iterations to converge. They also put high computational demand on the computational agents. In this paper we show that in case the coupled problem has an inherent tree structure, it is possible to devise an efficient distributed algorithm for solving such problems. The proposed algorithm relies on predic

Claudin-2 promotes breast cancer liver metastasis by enabling seeding and early cancer cell survival. We now demonstrate that the PDZ-binding motif of Claudin-2 is necessary for anchorage-independent growth of cancer cells and is required for liver metastasis. Several PDZ domain-containing proteins were identified that interact with the PDZ-binding motif of Claudin-2 in liver metastatic breast can

PURPOSE: The aim of this study was to describe long-term adjustment to life with an ileal pouch-anal anastomosis after surgery for ulcerative colitis, to investigate the relationship of pouch function to adjustment, and to explore factors affecting quality of life.METHODS: A total of 369 patients treated between 1982 and 1993 were included in the study. Questionnaires designed to assess bowel (pou

The inverse of the standard estimate of covariance matrix is frequently used in the portfolio theory to estimate the optimal portfolio weights. For this problem, the distribution of the linear transformation of the inverse is needed. We obtain this distribution in the case when the sample size is smaller than the dimension, the underlying covariance matrix is singular, and the vectors of returns a

Many cryptographic primitives rely on word rotations (R) and xor (X) to provide proper mixing. We give RX-system mixing a very general treatment and deduce some theoretical results on related probability distributions. Pure RX-systems are easy to break, so we show how to apply our theory to a more complex system that uses RX operations in combination with S-boxes. We construct an impractical (key

An ensemble of LDPC convolutional codes with parity-check matrices composed of permutation matrices is considered. The convergence of the iterative belief propagation based decoder for terminated convolutional codes in the ensemble is analyzed for binary-input output-symmetric memoryless channels using density evolution techniques. We observe that the structured irregularity in the Tanner graph of

It is becoming more and more common to exercise regularly, and with this new fitness trend follows more exercise applications to our smartphones. Applications aiming to help us exercise by structuring and logging our training. The user experience for these applications can be a little bit dull, since most of the applications depend on the user following instructions and entering input of the resul

Although invasive species are recognized as a major threat to freshwaters, little is known about how future climate warming will affect the success of invaders. Ecosystems are also often simultaneously impacted by multiple, potentially interacting, invading species and the management of species invasions can be incredibly difficult. Sensitive methods such as environmental DNA (eDNA) metabarcoding,

In this thesis, we present and study a few approaches for constructing controllers for uncertain systems, using a combination of classical control theory and modern machine learning methods. The thesis can be divided into two subtopics. The first, which is the focus of the first two papers, is dual control. The second, which is the focus of the third and last paper, is multiple-input multiple-outp

High-energy proton-proton collisions such as the ones happening at the LHC can result in the formation of the QGP, a state of matter similar to the early Universe's. One property of the QGP is strangeness enhancement, leading to the formation of strange flavoured particles such as $\Xi$, $\Lambda$ or $K$. The aim of this thesis is to study the production mechanism of a strangeness-balanced tri

Polymers have existed in the manufacturing scenario for a long time now. However, the surprising part is that the data for metal cutting is still being incorporated for machining of polymers. Polymers are often machined using the tools on the data available for soft materials like aluminum. There is little research done in the domain of machinability of polymers to find out the best cutting combin
