08:30 - 09:30 Monthly SeminarFoundation of Physics Group Can nonlocal quantum correlations be shared by two or more observers? School PHYSICS Class A, Ground Floor, Farmanieh Building ... 12:00 - 13:15 Analysis SeminarFrames in Hilbert $C^*$-modules School MATHEMATICS Whether every Hilbert $C^*$-module over a $C^*$-algebra $A$ admits a frame, is an interesting open question in Hilbert $C^*$-module theory. In general, the response to this question is negative and every Hilbert $C^*$-module over a commutative $C^*$-algebra $A$ admits a frame if and only if $A$ is a finite dimensional $C^*$-algebra. Indeed, the conjecture is that every Hilbert $C^*$-module over a $C^*$-algebra $A$ admits a frame, if and only if $A$ is a $C^*$-algebra of compact operators. The main purpose of this talk is to give a partially affirmative response to this conjecture, by considering the Elliott-Kawamura categorical approach to ... 14:00 - 15:00 Weekly SeminarStatistical physics of medical diagnostics School NANO SCIENCES Statistical physics of medical diagnosticsStatistical physics has been widely used to extract macroscopic properties of a wide range of systems from their microscopic interaction models, yet it has not been employed to medical diagnostics. Given an initial subset of observed signs (symptoms, clinical and laboratory findings) with some prior knowledge about the patient (or a complex system like a biological cell), a diagnosis problem simply asks for the most probable diseases (or macrostates with specific phenotypes). An efficient and accurate diagnostic procedure is important specially in the early stages of diseases, where ... 14:00 - 16:00 SeminarOptimal localist and distributed coding of spatiotemporal spike patterns through STDP and coincidence detection School COGNITIVE SCIENCES Abstract: Repeating spatiotemporal spike patterns exist and carry information. Here we investigated how a single spiking neuron can optimally respond to one given pattern (localist coding), or to either one of several patterns (distributed coding, i.e. the neuron's response is ambiguous but the identity of the pattern could be inferred from the response of multiple neurons), but not to random inputs. To do so, we extended a theory developed in a previous paper (Masquelier 2017 Neuroscience), which was limited to localist coding. More specifically, we computed analytically the signal-to-noise ratio (SNR) of a multi-pattern-dete ... 14:00 - 15:00 Weekly SeminarCondensed Matter and Statistical Physics Group Statistical physics of medical diagnostics School PHYSICS Seminar Room (classroom A), Farmanieh Building, IPM ... |
