Dolphin: An Actor-Oriented Database for Reactive Moving Object Data Management
Yiwen Wang, VIvek Shah, Marcos Antonio Vaz Salles, Claudia Bauzer Medeiros, Julio Cesar dos Reis & Yongluan Zhou
Novel reactive moving object applications require solutions to support object reactive behaviors as a way to
query and update dynamic data. While moving object scenarios have long been researched in the context of
spatio-temporal data management, reactive behavior is usually left to end-user implementations. However,
it is not just a matter of hardwiring reactive constraints: the required solutions need to satisfy tight lowlatency
computation requirements and be scalable. This emerging class of applications builds on...

Hence, Translation services are essential for various sectors....
Bound Quantum Mechanics, Classical Mechanics and Flow/Flux Scheme
Francesco R. Ruggeri
In a previous note (1), we argued that both free particle quantum and classical mechanics follow from an energy flow/flux scheme based on: d/dx (partial) A(x,t) = p ((1a)) and d/dt (partial) A(x,t) = -E ((1b)) A(x,t) turns out to be the classical action tL(v) (L=Lagrangian) with x/t=v and the above hold for both the relativistic and nonrelativistic cases. We further argued that ((1a)) and ((1b)) lead to two sets of solutions, one classical...

Proof of Fermat Last Theorem based on successive presentations of pairs of odd numbers
Yuri K. Shestopaloff
A simpler proof of Fermat Last Theorem (FLT), formulated by Fermat in 1637, is suggested. The initial equation x^n + y^n = z^n is considered not in natural, but in integer numbers. It is subdivided into four equations based on parity of terms and their powers. All cases converge to one equation, which is studied using presentation of pairs of odd integers with a successively increasing presentation factor of 2^r. At each presentation level, the...

We demonstrate how and why an electron’s 4π full rotation returning to its initial state quantum characteristic measured in the lab frame is a special relativity effect. Keywords: . © The Authors 2021.
News Sharing Networks Expose Information Polluters on Social Media
Bao Tran Truong, Oliver Melbourne Allen & Filippo Menczer
The dataset includes networks constructed from COVID-related tweets for detecting low-credibility accounts.
We provide three CSV files, corresponding to three networks: the misinformation retweet, the bipartite news-sharing, and the news co-sharing network. All files are tab-separated edge lists; Node labels indicate their credibility: high, low, or unknown (0, 1, and -1 respectively). An account score is a weighted mean of shared domain scores. Binary labels are provided for sources, rather than scores, to comply with...

Center-of-Mass, Schrodinger Bound State and Hydrodynamics
Francesco R. Ruggeri
There have been various derivations of the Schrodinger equation in the literature (e.g. (1)) based on hydrodynamics (continuity and conservation of momentum equations) with the added assumption that a velocity field u(x,t) = d/dx S(x,t) where S(x,t) is a new field. Furthermore a mathematical transformation Wv= sqrt(d(x,t)) exp(i S(x,t)) is used leading to the new function Wv(x). In (2) we compared the bound state Schrodinger scenario to the hydrodynamic equations in (1). In...

Modification of Fermi-Dirac/Bose-Einstein Distributions Based on Pure State Entropy?
Francesco R. Ruggeri
In a previous note (1) we argued that for a wavefunction W(x,t)= Sum over n an exp(iEnt) Wn(x), the entropy for a particle in a box with infinite potential walls from (2) is: S/(-k)= Sum over n |anan| ln |anan| ((1)) and should be modified to: S/(-k)= Sum over n |anan| ln|anan| + |anan| Sp(n,L) + |anan| Sx(L) ((2)) where Sp and Sx are the pure state momentum and spatial entropies i.e Sp/-k...

Hernández Sánchez, Jordi Peña-Casanova, J Roquer González, Anna Padrós Fluvià & Victor Puente Periz
Summary: Introduction: The analysis of the core biomarkers of Alzheimer's Disease (AD) in the cerebrospinal fluid (CSF) is recommended in the clinical units where it is available. Because of the absence of universal validated values, the determination of specific cut-off points for each center and its population is recommended. The main objective of the CORCOBIA study was to determine the cut-off points of core AD CSF biomarkers for several centers (Parc de Salut Mar,...

Introducing Multi-dimensional Currency Systems
We show how fundamental concepts in multidimensional currencies can underpin next-generation governance capabilities for complex marketplaces and commercial ecosystems. The addition of non-monetary parameters in an nD currency system can help regulate the use of the currency itself, as well as give rise to novel properties that could influence the policy and evolution of the associated ecosystem. We show, for example, how a 2D currency that has energy as its non-monetary component gives rise to...
Microclimate temperature variations from boreal forests to the tundra
Juha Aalto, Vilna Tyystjärvi, Pekka Niittynen, Julia Kemppinen, Tuuli Rissanen, Hilppa Gregow & Miska Luoto
Microclimate varies greatly over short horizontal and vertical distances, and timescales. This multi-level heterogeneity influences terrestrial biodiversity and ecosystem functions by determining the ambient environment where organisms live in. Fine-scale heterogeneity in microclimate temperatures is driven by local topography, land and water cover, snow, and soil characteristics. However, their relative influence over boreal and tundra biomes and in different seasons, has not been comprehensively quantified. Here, we aim to 1) quantify temperature variations measured at...
Ideal Gas Law, Quantum Thermodynamics and Pure Bound States
Francesco R. Ruggeri
In (1) the ideal gas result P V (to the power gamma) = constant ((1)) where gamma=cp/cv=5/3 is applied to a pure quantum bound state for a particle in a box with infinite potential walls and it is seen that ((1)) is a constant just as in the case of an ideal gas. This, however, depends on the result PV=nRT. {An ideal gas, however, follows from a Maxwell-Boltzmann distribution which is linked to the equipartition...
Crazy Representations of Natural Numbers From 200001 to 220000
Inder J. Taneja
During past years author worked with representations of numbers in terms of 1 to 9 and 9 to 1. These representations called as crazy representations, and are done from 0 to 200000. For details see the references. This work brings natural numbers from 200001 to 220000 written in ascending and descending orders of 1 to 9 and 9 to 1. The numbers are obtained by using basic operations along with factorial. Few numbers are by...
Modeling the transplacental transfer of small molecules: A case study on poly/perfluorinated substances (PFAS)
Dimitri Abrahamsson, Adi Siddharth, Joshua F. Robinson, Anatoly Soshilov, Sarah Elmore, Vincent Cogliano, Carla Ng, Elaine Khan, Randolph Ashton, Weihsueh A. Chiu, Lauren Zeise & Tracey J. Woodruff
Background: Despite their large numbers and widespread use, very little is known about the extent to which per- and polyfluoroalkyl substances (PFAS) are transferred to the fetus during pregnancy. Objective: The aim of our study is to develop computational approaches that can be used to evaluate the extent to which PFAS can cross to cross the placenta and partition to cord blood. Methods: We collected experimental values of the central tendency of concentration ratio between...
