Some Basic Theories of Random Normed Linear Spaces and Random Inner Product Spaces [PDF]
, 1999 首先提出随机度量空间定义的另一个提法，这提法不仅等价于原始的定义而且也使随机度量空间自动归入广义度量空间的框架，也考虑了关于拓扑结构的某些新的问题；循着同样的思路，对随机赋范空间的定义也作了新的处理并同时简化了随机赋范模的定义.其次本文也证明了一个E-范空间的商空间等距同构于一个典型的E-范空间；进一步，在概率赋范空间的框架下证明了一个概率赋伪范空间是伪内积生成空间的充要条件是它等距同构于一个E-内积空间，这回答了C.AlSInA与b.SCHWEIzEr等人新近提出的公开问题.最后 ...

PPO‐Based Reinforcement Learning for the Semi‐Active Vibration Control of MDOF Platform
AI &Innovation, EarlyView.ABSTRACT Aiming at the coupled vibration problem of a multi‐degree‐of‐freedom (MDOF) vibration isolation platform under eccentric excitation, this paper proposes a semi‐active vibration control strategy based on Proximal Policy Optimization (PPO) ‐based reinforcement learning (PPO RL).

Isomorphically isometric probabilistic normed linear spaces.
, 1979 Probabilistic normed linear spaces (briefly PNL spaces) were first studied by A. N. Serstnev in [1]. His definition was motivated by the definition of probabilistic metric spaces (PM spaces) which were introduced by K.

American Journal of Agricultural Economics, EarlyView.Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Some properties of continuous linear operator in topological vector PN spaces
, 2010 The notion of a probabilistic metric space corresponds to the situations when we do not know exactly the distance. Probabilistic Metric space was introduced by Karl Menger.

D-bounded sets in probabilistic normed spaces and in their products
, 2001 A sufficient, but not necessary, condition is given for the family of D-bounded subsets in a Probabilistic Normed space(briefly PN space)to be a linear space when it is endowed with suitably defined operations of addition and multiplication by a scalar ...

The topological structure of a certain Menger space
, 2007 In this paper we will reconsider the topological structure of Menger probabilistic normed spaces (briefly PN-spaces) under the t-norm M. We will prove that this topology is compatible with the topology induced by a countable and separating family of semi-

Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease
Annals of Neurology, EarlyView.Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

Convexity in quasi-metric spaces
, 2012 Includes abstract.Includes bibliographical references.The principal aim of this thesis is to investigate the existence of an injective hull in the categories of T-quasi-metric spaces and of T-ultra-quasi-metric spaces with nonexpansive ...

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...
