Abstract To address the central question of how climate change influences tree growth within context global warming, we used dendroclimatological analysis to understand reactions four major boreal species – Populus tremuloides, Betula papyrifera, Picea mariana , and Pinus banksiana climatic variations along a broad latitudinal gradient from 46 54°N in eastern Canadian forest. Tree‐ring chronologies 34 forested stands distributed at 1° interval were built, transformed into principal...
Recently, the minimization of a sum two convex functions has received considerable interest in variational image restoration model. In this paper, we propose general algorithmic framework for solving separable problem from point view fixed algorithms based on proximity operators (Moreau 1962 C. R. Acad. Sci., Paris I 255 2897–99). Motivated by proximal forward–backward splitting proposed Combettes and Wajs (2005 Multiscale Model. Simul. 4 1168–200) operator (FP2O) denoising (Micchelli et al...
High‐resolution climate proxy records covering the last two millennia on Qinghai‐Tibetan Plateau are scarce yet essential to evaluation of patterns, synchroneity and spatial extent past climatic changes including those in Medieval Warm Period (MWP) Little Ice Age (LIA). Here we present a 2326‐year tree‐ring chronology Sabina przewalskii Kom. for Dulan area northeastern Plateau. We find that annual growth rings mainly reflect variations regional spring precipitation. The greatest change...
The CO 2 fertilization hypothesis stipulates that rising atmospheric has a positive effect on tree growth due to increasing availability of carbon. objective this paper is compare the recent literature related both field -enriched experiments with trees and empirical dendrochronological studies detecting effects in tree-rings. This will allow evaluation responses enrichment by combining evidence from ecophysiology tree-ring research. Based considerable experimental direct (increased...
This paper addresses two problems in linear discriminant analysis (LDA) of face recognition. The first one is the problem recognition human faces under pose and illumination variations. It well known that distribution images with different pose, illumination, expression complex nonlinear. traditional methods, such as LDA, will not give a satisfactory performance. second small sample size (S3) problem. occurs when number training samples smaller than dimensionality feature vector. In turn,...
Adaptive filtering algorithms operating in reproducing kernel Hilbert spaces have demonstrated superiority over their linear counterpart for nonlinear system identification. Unfortunately, an undesirable characteristic of these methods is that the order filters grows linearly with number input data. This dramatically increases computational burden and memory requirement. A variety strategies based on dictionary learning been proposed to overcome this severe drawback. In literature, there no...
Nonthermal plasma (NTP) systems combined with the supported metal catalyst is a promising method to enable CO2 valorisation under mild conditions. However, insight into relationships between microstructure and catalytic performance NTP conditions still lacking. Herein, Ru nanoparticles (NPs) on ZSM-5 zeolites different zeolite morphologies (i.e., nanocrystals, nanosheets conventional large crystals) NPs locations externally supported, internally encapsulated combination of two) obtained by...
Gut Akkermansia muciniphila (Akk) has been implicated in impacting immunotherapy or oncogenesis. This study aims to dissect the Akk-associated tumor immune ecosystem (TIME) by single-cell profiling coupled with T cell receptor (TCR) sequencing. We adopted mouse cancer models under anti-PD-1 immunotherapy, combined oral administration of three forms Akk, including live pasteurized Akk (Akk-past), its membrane protein Amuc_1100 (Amuc). show that is most effective activation CD8 cells rescuing...
The finite volume element method (FVE) is a discretization technique for partial differential equations. This paper develops energy error estimates general self-adjoint elliptic boundary value problems with FVE based on triangulations, which there exist linear spaces, and very type of control volumes (covolumes). this are also optimal but the restriction conditions covolumes given in [R.

Abstract Many problems arising in image processing and signal recovery with multi-regularization constraints can be formulated as minimization of a sum three convex separable functions. Typically, the objective function involves smooth Lipschitz continuous gradient, linear composite nonsmooth function, function. In this paper, we propose primal-dual fixed point (PDFP) scheme to solve above class problems. The proposed algorithm for three-block is symmetric fully splitting scheme, only...
Abstract The world's hydrological cycle is believed to intensify with global warming, yet current climate models have only a limited ability assess moisture responses at regional scales. Tree‐ring records are valuable source of information for understanding long‐term, regional‐scale changes, particularly large regions such as the Tibetan Plateau (TP), where observational data short and sparse. Here, we present new ring‐width chronology developed from Qilian Juniper ( Sabina przewalskii )...
Abstract In this paper, we present a new approach, based on mixed model procedure, to quantify the tree‐ring‐based growth‐climate relationship of trembling aspen along latitudinal gradient from 46 54 °N in eastern Canada. This approach allows breaking down growth response into general intersite and local climatic responses, analyzing variations absolute ring width as well interannual tree growth. The final also integrates nonclimatic variables such soil characteristics occurrence insect...
The radiative transfer equation (RTE) occurs in a wide variety of applications. In this paper, we study discrete-ordinate discontinuous Galerkin methods for solving the RTE. numerical are formed two steps. first step, discrete ordinate technique is applied to discretize integral operator angular variable, resulting semidiscrete hyperbolic system. second spatial method A stability and error analysis performed on methods. Some examples included demonstrate convergence behavior
Immediate phenotypic variation and the lagged effect of evolutionary adaptation to climate change appear be two key processes in tree responses warming. This study examines these components types growth models for predicting 2010–2099 diameter four major boreal species Betula papyrifera, Pinus banksiana, Picea mariana, Populus tremuloides along a broad latitudinal gradient eastern Canada under future projections. Climate-growth response 34 stands over nine latitudes were calibrated...
This paper investigates energy allocation in underwater acoustic nodes powered by harvesting. Our goal is to maximize the expected total amount of delivered data over a finite time slots. Two scenarios are considered for different knowledge levels channel state information (CSI). In one scenario, transmitter receives CSI at end each transmission epoch and we consider problem sensing transmission. second delayed after multiple slots, while only considered. The modeled as finite-state Markov...
