Jensen-type geometric shapes [PDF]
Annales Universitatis Paedagogicae Cracoviensis. Studia Mathematica, 2020 Abstract We present both necessary and sufficient conditions for a convex closed shape such that for every convex function the average integral over the shape does not exceed the average integral over its boundary. It is proved that this inequality holds for n-dimensional parallelotopes, n-dimensional balls, and convex ...

The statistical shape of geometric reasoning [PDF]
Scientific Reports, 2018 Abstract Geometric reasoning has an inherent dissonance: its abstract axioms and propositions refer to perfect, idealized entities, whereas its use in the physical world relies on dynamic perception of objects. How do abstract Euclidean concepts, dynamics, and statistics come together to support our intuitive geometric reasoning? Here,

Benchmarking End-to-end Learning of MIMO Physical-Layer Communication [PDF]
, 2020 End-to-end data-driven machine learning (ML) of multiple-input multiple-output (MIMO) systems has been shown to have the potential of exceeding the performance of engineered MIMO transceivers, without any a priori knowledge of communication-theoretic ...

, 1996 In this survey we consider geometric techniques which have been used to measure the similarity or distance between shapes, as well as to approximate shapes, or interpolate between shapes. Shape is a modality which plays a key role in many disciplines, ranging from computer vision to molecular biology.

Compression induced intercellular shaping for some geometric cellular lattices
Brazilian Archives of Biology and Technology, 2001 The wall perimeter fraction, which contact neighboring cells, was named compression ratio (alpha). A zero compression ratio indicates maximum intercellular (air) volume (vG, v/v) and neglectable contact among cells, while alpha=1 indicates complete ...

IEEE Access, 2021 An aggregating switch (SW) network offers cost-effective accommodation to Internet-of-Things (IoT) traffic by aggregating the traffic. In such a network, it is crucial to eliminate the discarded traffic caused by the simultaneous transmission of massive ...

Probabilistic Shaping for Finite Blocklengths: Distribution Matching and Sphere Shaping [PDF]
, 2019 In this paper, we provide for the first time a systematic comparison of distribution matching (DM) and sphere shaping (SpSh) algorithms for short blocklength probabilistic amplitude shaping.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
