Bootstrapping of FHE over the Integers with Large Message Space [PDF]

Security and Communication Networks, 2018
For the decryption of the fully homomorphic encryption (FHE) over the integers with the message space ZQ, Nuida and Kurosawa proposed a Q4λ-multiplicative-degree circuit to compute it at Eurocrypt 2015, where λ is the security parameter and the message size Q is a constant. Since the degree of the decryption circuit is polynomial in Q, the range of the

Bootstrap for integer‐valued GARCH(p, q) processes [PDF]

Statistica Neerlandica, 2021
AbstractWe consider integer‐valued processes with a linear or nonlinear generalized autoregressive conditional heteroscedastic models structure, where the count variables given the past follow a Poisson distribution. We show that a contraction condition imposed on the intensity function yields a contraction property of the Markov kernel of the process.

Local Search and the Evolution of World Models

Topics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

Improving GNSS Ambiguity Acceptance Test Performance with the Generalized Difference Test Approach

Sensors, 2018
In Global navigation satellite system (GNSS) data processing, integer ambiguity acceptance test is considered as a challenging problem. A number of ambiguity acceptance tests have been proposed from different perspective and then unified into the integer

A Clinical Prediction Model for Selective NT-proBNP Testing in Hypertension. [PDF]

J Clin Hypertens (Greenwich)
ABSTRACT N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) testing is recommended for pre‐heart failure (pre‐HF) screening. However, universal NT‐proBNP testing is infeasible and inefficient. We analyzed data from 4642 U.S. adults with hypertension in NHANES 1999–2004.

Mixed Taper Equations for African Mahogany Plantations ( Khaya grandifoliola C. DC.) Near Thinning and Clear-cut Ages [PDF]

Floresta e Ambiente
The present study aimed to develop taper equations for African mahogany trees in two important ages (near to thinning and near to clear-cut ages), using, respectively, 100 seven-year-old trees were scaled in Minas Gerais and 46 fourteen- and fifteen-year-

An Improved Ambiguity Resolution of Three Carriers in Precise Point Positioning

IEEE Access, 2018
Precise point positioning (PPP) is of great importance in fields requiring coordinates with high accuracy, such as geophysics, meteorology, and geodesy. Compared with relative positioning restricted by the length of baseline, PPP using a single receiver ...

Accounting for animal health in efficiency analysis: An application to Swedish dairy farms

American Journal of Agricultural Economics, EarlyView.
Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.
