Analysis of the amplitude form of the quantum hash function
Учёные записки Казанского университета: Серия Физико-математические науки, 2023 In this article, the properties of quantum hash functions are further explored. Previous findings show that so-called small-bias sets (special subsets of the set of elements of a cyclic group) generate a “phase” quantum hash function. Here, it was proved

Ship resistance in random ice field of small ice floes made of the substitute material
Zhongguo Jianchuan Yanjiu, 2022 ObjectivesThis study focuses on the feasibility of a ship resistance model test in an ice field of small ice floes made of substitute material in order to reveal the resistance components and thereby provide technical support for the design of ice-going ...

On Quantum Collision Resistant Function [PDF]
Uchenye Zapiski Kazanskogo Universiteta. Seriya Fiziko-Matematicheskie Nauki, 2021 In the classical hashing theory, collision is a coincidence of the values of a function with different arguments. This paper formulates a quantum analogue of the collision property. A variant of formalization of the concept of quantum function resistant to collisions was proposed.

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose A set of treatment planning strategies were designed and retrospectively implemented for locally advanced, non‐small cell lung cancer (NSCLC) patients in order to minimize cardiac dose without compromising target coverage goals. Methods Retrospective analysis was performed for 20 NSCLC patients prescribed to 60–66 Gy that received a ...

A small footprint couch‐top support device for image‐guided radiotherapy of heavy patients
Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose Patients with body weights close to or above 400 lbs present unique challenges in radiation therapy since the weight limit of most treatment couches decreases as the couch‐top extends toward the treatment gantry. The purpose of this work was to develop a small footprint couch‐top support platform to safely perform image‐guided ...

Strong accumulators from collision-resistant hashing [PDF]
International Journal of Information Security, 2008 Accumulator schemes were introduced in order to represent a large set of values as one short value called the accumulator. These schemes allow one to generate membership proofs, that is, short witnesses that a certain value belongs to the set. In universal accumulator schemes, efficient proofs of non-membership can also be created.

Flexural Behavior of Bidirectionally Graded Lattice
Advanced Engineering Materials, EarlyView., 2023 An experimental study of the bending behavior of bidirectional body‐centered cubic lattice beams is conducted in comparison to uniform and unidirectional counterparts of electron beam melted SS 316 L. Experimental results are used to develop and validate a finite element model which is subsequently used to conduct parametric studies to assess the ...

On the origin and the amplitude of T-square resistivity in Fermi liquids [PDF]
Annalen Der Physik 534, 2100588.(2022), 2021 In 1937, Baber, Landau and Pomeranchuk postulated that collisions between electrons generates a contribution to the electric resistivity of metals with a distinct T$^2$ temperature dependence. The amplitude of this term is small in common metals, but dominant in metals hosting either heavy carriers or a low concentration of them.
