Examples of cylindrical Fano fourfolds [PDF]

open access: yes, 2016
International audienceWe construct 4 di erent families of smooth Fano fourfolds with Picard rank 1, which contain cylinders, i.e., Zariski open subsets of the form Z x A1, where Z is a quasiprojective variety. The affi ne cones over such a fourfold admit

Rationality and equivariant birational geometry of Fano varieties [PDF]

open access: yes
This thesis is about birational geometry of Fano varieties and their properties. Firstly, we study the rationality of Fano-Enriques threefolds, which are certain three-dimensional non-Gorenstein Fano varieties of index 1 with at most canonical ...

Uniformity of Vector Bundles of Finite Rank on Complete Intersections of Finite Codimension in a Linear ind-Grassmannian

open access: yesМоделирование и анализ информационных систем, 2015
A linear projective ind-variety X is called 1-connected if any two points on it can be connected by a chain of lines l1, l2, ..., lk in X, such that li intersects li+1.

Full counting statistics of Yu-Shiba-Rusinov bound states

open access: yesPhysical Review Research, 2023
With the help of scanning tunneling microscopy (STM) it has become possible to address single magnetic impurities on superconducting surfaces and to investigate the peculiar properties of the in-gap states known as Yu-Shiba-Rusinov (YSR) states.

On the Chow ring of certain Fano fourfolds

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2020
We prove that certain Fano fourfolds of K3 type constructed by Fatighenti–Mongardi have a multiplicative Chow–Künneth decomposition. We present some consequences for the Chow ring of these fourfolds.

Electromagnetically Induced Transparency in Symmetric Planar Metamaterial at THz Wavelengths

open access: yesPhotonics, 2015
We report the experimental observation and the evidence of the analogue of electromagnetically-induced transparency (EIT) in a symmetric planar metamaterial. This effect has been obtained in the THz range thanks to a destructive Fano-interference between

Neural network mechanisms underlying stimulus driven variability reduction. [PDF]

open access: yesPLoS Computational Biology, 2012
It is well established that the variability of the neural activity across trials, as measured by the Fano factor, is elevated. This fact poses limits on information encoding by the neural activity.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Fano 3-folds, K3 surfaces and graded rings [PDF]

open access: yes, 2002
Explicit birational geometry of 3-folds represents a second phase of Mori theory, going beyond the foundational work of the 1980s. This paper is a tutorial and colloquial introduction to the explicit classification of Fano 3-folds (Q-Fano 3-folds), a ...
