Title: DNA Rendering of Polyhedral Meshes at the Nanoscale

Abstract: The presentation will concentrate over the newly introduced algorithmic design scheme for DNA-based 3D polyhedral nanostructures. The technique introduces a way of tracing a long DNA scaffold strand through these structures, using a "one helix per edge" principle, thus enabling the design of structures that could not previously be realized before. The fully automated design process takes arbitrary polygonal mesh designs and converts them to molecular designs suitable for DNA nanostructure folding. A routing algorithm, based on Eulerian paths, and a relaxation simulation, are used to traverse the scaffold across the edges of the triangulated meshes. Both the fundamental design methods as well as concrete examples and their experimental implementations will be presented.

"Perspectives of feature selection in bioinformatics: from relevance to causal inference"

Abstarct: A major goal of the scientific activity is to model real phenomena by studying the dependency between entities, objects or more in general variables. Sometimes the goal of the modeling activity is simply predicting future behaviors. Sometimes the goal is to understand the causes of a phenomenon (e.g. a disease). Finding causes from data is particular challenging in bioinformatics where often the number of features (e.g. number of SNPs or microarray probes) is huge with respect to the number of samples. In this context, even when experimental interventions are possible, performing thousands of experiments to discover causal relationships between thousands of variables is not practical. Dimensionality reduction techniques have been largely discussed and used in bioinformatics to deal with the curse of dimensionality. However, most of the time these techniques focus on improving prediction accuracy, neglecting causal aspects. This talk will discuss a major open issue : may feature selection techniques be useful also for causal feature selection? Is prediction accuracy compatible with causal discovery? Some results based on an information theory approach will be used to illustrate the issue.

TUCS Distinguished Lecture Series

         Title: “Standing on the Shoulders of a Giant: One Person’s Experience of Turing’s Impact”

         Host: Ion Petre, Åbo Akademi and Turku Centre for Computer Science

Abstract: The talk will briefly describe three of Turing’s major achievements, in three different fields: computability, biological modeling and artificial intelligence.  Interspersed with this, I will explain how each of them directly motivated and inspired me to work on a number of topics over a period of 30 years, the results of which can all be viewed humbly as extensions and generalizations of Turing’s pioneering and ingenious insights.

Title: “Design and Implementation of Adaptive Stream Mining Systems using Lightweight Dataflow Graphs”

Host: Prof. Johan Lilius, Åbo Akademi University

 

Abstract: With the increasing need for accurate mining and classification from multimedia data content, and the growth of such multimedia applications in mobile and distributed architectures, stream mining systems require increasing amounts of flexibility, extensibility, and adaptivity for effective deployment. In this talk, I will present a novel approach to address this challenge. This approach rigorously integrates foundations of dataflow modeling for high-–level signal processing system design, and adaptive stream mining based on dynamic topologies of classifiers. In particular, I will introduce a new design environment, called the lightweight dataflow for dynamic data driven adaptive systems (LiD4E) environment. LiD4E provides formal semantics, rooted in dataflow principles, for design and implementation of a broad class of multimedia stream mining topologies. I will demonstrate the utility of these new design methods on an energy–constrained, multi–mode stream mining system for face detection.

This work is joint with Kishan Sudusinghe, Inkeun Cho, and Mihaela van der Schaar.

Title: "Looking for Computers in the Biological Cell. After Twenty Years"

Host: Ion Petre, Åbo Akademi and Turku Centre for Computer Science

Abstract: A glimpse on natural computing is carried out, with an autobiographical eye, hence with some details about DNA computing and membrane computing. Besides (types of) problems and results (applications included), some research directions are mentioned which need further efforts. Then the question is raised whether or not "we dream too much" in this area, of bio-inspired computing. Some "impossibility theorems" as those of R. Gandhy and M. Conrad are mentioned.

CV: Gheorghe Paun is a researcher in the Institute of Mathematics of the Romanian Academy, Bucharest. Interested in formal language theory, automata theory, mathematical linguistics, DNA computing, and membrane computing. Long research stages in Germany, Finland, The Netherlands, Canada, Spain, Japan, many visits in universities from other countries (over 100 collaborators from all these countries). Several of his books, written alone or in collaboration, became standard references, e.g., in regulated rewriting, Marcus contextual grammars, grammar systems, DNA computing, membrane computing. This last research area was initiated by him, in 1998, see TUCS Technical Report No. 208, November 1998, www.tucs.fi) and it was soon considered by ISI as a "fast emerging research area of computer science". A comprehensive coverage of the domain is "The Oxford Handbook of Membrane Computing", 2010, edited by Gh. Paun, G. Rozenberg, A. Salomaa.

Gh. Paun is a member of the Romanian Academy and of Academia Europaea.

New course: Logic for High School Mathematics

Special course in Computer Science

Special course in Mathematics

Lectures: Wednesdays 14 - 16.

Excercises: Wednesdays 13 - 14.

Course duration: April 1 - May 27

Place: ICT House, room B3040  (Cobol)

Lecturer: Ralph-Johan Back

The course starts on April 1, at 14, in Cobol . More information about the course is given on the course web page: http://users.abo.fi/backrj/HighSchoolLogic/

 

The course is intended for M.Sc and Ph.D. students in Mathematics, Computer Science and Computer Engineering. Lectures are in English,  but assignments can be done in Finnish, Swedish or English.

Course description: Mathematics is based on logic. But logic is not really used in practice in high school mathematics.  A course on logic may be offered in the curriculum, but it is usually taught as a separate course, focusing on the foundations of mathematics, rather than seeing logic as a  tool  that can be used in all mathematics throughout high school. Our aim in this course is to show how logic can be used as a highly practical tool for solving mathematical problems in high school and first year university courses. We base our approach on structured derivations,  a new format for presenting mathematical calculations, proofs and general derivations. We show how  the use of logic in combination with structured derivations allows us to present clear and easily understandable solutions to rather complicated mathematical problems. We will present the basics of  propositional calculus and predicate calculus in this course, and show how these reasoning tools can be used in typical high school problem solving.  Our aim is also to present a simple general reasoning framework that we hope will clear up much of the conceptual mess that many students experience when trying to understand the underlying logic behind informal mathematical argumentations.  The last part of the course treats some more advanced topics, like induction proofs and the epsilon-delta method.

Organising of INFORTE.fi courses

Inforte.fi program started operating originally in 2001.During this wholeperiod, the Inforte.fi program has however maintained its standing as a stat- wide program for ICT professionals. It is designed to offer networking and education events to PhD students and professionals working in Finnish companies, polytechnics and public administration. Invited speakers are some of the top international researchers or industry representatives in their field. Inforte.fi’s member university departments will annually organize about 12 workshops and seminars on diverse areas of ICT. The main areas of focus are:

These intensive events can be used as tools for professional education, or as parts of doctoral education. Inforte.fi program delivers certificates of participation, and participants negotiate how these achievements can be included in their studies with their home universities. Inforte.fi events are a way to connect you with other ICT professionals and academics in your field, and build important social networks. Inforte.fi events allow you to update your knowledge and keep on track with the latest scientific and practical knowledge in the ICT field.

HOW TO COME ALONG?

Anyone within the member departments can suggest an event. We hope that the event is in line with our main areas of focus. If you have something in mind, contact the Inforte.fi staff and let’s start planning the event!

Inforte.fi’s member university departments are:

ABOUT ORGANIZING INFORTE.FI EVENTS

The organizer’s payment for organizing an one-day event is 250 € and for a two-day event 500 €. The organizer has to send the Inforte.fi staff his or hers separate tax card or otherwise the Finnish tax authorities will take off 60 % taxes from the payment. Inforte.fi staff will send the organizer a travelling expenses claim form and a bank and personal information form. The travelling expenses claim form needs to be filled only if needed, but the bank and personal information form needs to be filled always. The Inforte.fi office will organize morning coffee with something small to bite to the events, but lunch and afternoon coffee can be bought at participant’s own expense. The organizer can however buy his/her and the speaker’s lunch and afternoon coffee and reimburse those expenses from the Inforte.fi office with the travelling expense claim. Also one feasible dinner with the speaker is allowed to reimburse with the travelling expense claim. However when using the travelling expenses claim, the organizer needs to send all of the original documents and receipts to Inforte.fi office (the address is at the bottom of this document).

The speaker’s payment Inforte.fi pays 120 € / lecturing hour and 60 € / group work hour at most. Lecturing fee is considered salary by Finnish tax office. Because the work is done in Finland, the Finnish tax authorities will automatically take off approximately 35 % taxes. In addition, it is mandatory to take off around 4 % other social security and pension contribution payments from the fee. This will happen automatically - no fee can be paid without these deductions.In addition to travel expenses and accommodation Inforte.fi will pay the speaker daily allowance. Daily allowance is 39 euros or 18 euros per travelling day. Inforte.fi will calculate the daily allowances. Inforte.fi does not cover meal expenses according to receipts. The fee and travel expenses will be paid separately and it may take approximately a month until the payment is on the speaker’s bank account.

The speaker’s travelling and accommodation

Inforte.fi pays for the speakers travelling and accommodation expenses and helps with the arrangements regarding these. If the Inforte.fi event will be merged with other activities in Finland (e.g. seminars) or during the trip, Inforte.fi will pay only a part of the expenses. If the speaker decides to book the trip independently, he/she needs to be in contact with the Inforte.fi staff because only travelling in Economy class will be accepted as expenses. Inforte.fi will book the hotel for the speaker.

Date and other important information about the event

The date of the event has to be agreed on in good time and the Inforte.fi staff has to be informed about it immediately after that. In addition to this the Inforte.fi staff will need the following information as soon as possible:

Remote access

The organizer has to agree with the speaker if participants can be included in the event with remote access. If both sides agree that it can be handled, the organizer has to find out that with what kind of system the speaker is used to and whether the remote access is possible to organize at the event location.
