Centre for Electronics

Online Teams Link Summary In many applications, the sensor array's geometrical layout is assumed to be fixed and given in advance. However, it is possible to change the geometrical layout of the array including adjacent sensor spacing and these additional spatial degrees of freedom (DOFs) can be exploited to improve the performance in terms of either beamforming or direction finding or both. With the development of compressive sensing (CS) or the sparsity maximization framework, a new CS...

Hernan Makse (City U New York): Can symmetry describe Biological (and Artificial) complexity?
Centre for Complex Systems

Symmetry is the cornerstone of theoretical physics, playing a crucial role across various scales. The pervasive presence of symmetries in the physical universe compels us to examine the question: if life arises as an emergent property from physical...

Seminar: Petr Jizba (Prague): Thermodynamics in Cosmology and Cosmology in Thermodynamics
Centre for Complex Systems

It is strongly expected that a new physical understanding of the role of entropy in the transition from thermodynamics to gravity should provide new ingredients and insights for modern cosmology and in particular for such pressing issues as dark...

Centre for Electronics

Online Teams Link Summary The concept of Cyber-Prosthesis redefines implantable devices not only as mechanical surrogates but also as bodycentric wireless nodes capable of sensing, storing, and transmitting biophysical information. Within this paradigm, the structural components of prosthetic implants—such as orthopedic fixtures, dental screws, stents, and heart valves—are converted into antenna systems operating in the UHF RFID band. These systems communicate through body tissues by...

Centre for Electronics

Online Teams Link Summary Although technical challenges are still daunting, the clinical utility of neuroprosthetics has increased dramatically over the past few years. This has been accomplished through the convergence of numerous disciplines, which have individually added fundamental understanding/capabilities to systems that interface with the human body to restore senses and movement, or treat prevalent diseases that have currently no foreseeable cure. In this talk, we will cover...

13:00 - 14:00
Seminar: Gadi Fibich (Tel Aviv U): Spreading Processes on Networks
Centre for Complex Systems

Spreading of innovations and epidemics is a classical problem. Traditionally, they have been analyzed using compartmental models (Bass, SI, …), which implicitly assume that all the individuals are homogeneous and connected to each other. To relax...

Seminar: Yotam Smilansky (U Manchester): Dynamics and resonances of hyperbolic tilings
Centre for Complex Systems

Substitution rules provide a classical method for constructing aperiodic tilings of Euclidean space. In my talk I will describe how they may additionally generate tilings of the hyperbolic upper-half space, extending constructions previously...

Seminar: Dibyajyoti Mohanta (New York State U): From Sequence-Specific Fluorescence Fingerprints to Aging in RNA Condensates: Dynamics of Heteropolymer Systems
Centre for Complex Systems

Heteropolymer systems provide a versatile framework for understanding biomolecular phenomena across scales. In this talk, we bridge two distinct domains: (1) optical DNA mapping (ODM), a technique for generating sequence-specific fluorescence ...

Peter Orbanz (UCL): Limit theorems for distributions invariant under a group of transformations
Centre for Complex Systems

Consider a large random structure -- a stochastic process on the line, a random graph, a random field on the grid -- and a function that depends only on a small part of the structure. Now use a family of transformations to 'move' the domain of the...

Seminar: Vittorio Loreto (La Sapienza): Exploring the Adjacent Possible: a mathematical lens on Innovation and Evolution
Centre for Complex Systems

New experiences continuously reshape our lives, whether through encounters with novel ideas, social interactions, or technological advancements. While some of these experiences occur randomly, many unfold through intricate chains of correlation and...

Seminar: Enrico Amico (U Birmingham): Higher-order connectomics of human brain function
Centre for Complex Systems

Traditional models of human brain activity often represent it as a network of pairwise interactions between brain regions. Going beyond this limitation, recent approaches have been proposed to infer higher-order interactions from temporal...
