Functional and Local Renormalization Groups [PDF]

open access: yes, 2015
We discuss the relation between functional renormalization group (FRG) and local renormalization group (LRG), focussing on the two dimensional case as an example.

Summer aspect of phytoplankton communities in some Montenegrin lakes: Are there changes after more than two decades? [PDF]

open access: yesArchives of Biological Sciences, 2012
Qualitative and quantitative phytoplankton compositions of 10 Montenegrin lakes were investigated in the summer of 2007. The obtained results were compared with a previous study-period that was undertaken two decades ago.

Synthesis and Characterization of Cross-Linked Polymer–Silica Composite Particles with Multi-Functional Groups

open access: yesMaterials Proceedings, 2023
Two types of core-shell composite particles, each comprising an aromatic poly(esteramide) (PEA) having amide and hydroxyl groups combined with silica (SiO2), were synthesized.

Class group L-functions

open access: yesDuke Mathematical Journal, 1995
Let \(K = \mathbb{Q}(\sqrt{-D})\) be an imaginary quadratic field with class number \(h\), and let \(\chi\) be any one of the \(h\) characters of the class group of \(K\). Then the class group \(L\)-functions \(L_K (s,\chi)\) are defined as natural generalizations of the Dedekind zeta-function.

Synthesis of biodegradable polyesteramides with pendant functional groups [PDF]

open access: yes, 1992
Morpholine-2,5-dione derivatives having substituents with benzyl-protected carboxylic acid, benzyloxycarbonyl-protected amine and p-methoxy-protected thiol groups, respectively, were prepared in 29-58% yield by cyclization of the corresponding N-[(2RS ...

Global functional calculus for operators on compact Lie groups [PDF]

open access: yes, 2014
In this paper we develop the functional calculus for elliptic operators on compact Lie groups without the assumption that the operator is a classical pseudo-differential operator. Consequently, we provide a symbolic descriptions of complex powers of such

Harvested Microalgal Biomass from Different Water Treatment Facilities—Its Characteristics and Potential Use as Renewable Sources of Plant Biostimulation

open access: yesAgronomy, 2020
Surface characteristics, physicochemical properties, functional groups, and bioactive compounds of microalgal biomass (MB) samples harvested from various wastewater treatment facilities (WTFs) were investigated to evaluate the reuse feasibility of MB as ...

High functional diversity is related to high nitrogen availability in a deciduous forest - evidence from a functional trait approach [PDF]

open access: yes, 2010
The current study tested the assumption that floristic and functional diversity patterns are negatively related to soil nitrogen content. We analyzed 20 plots with soil N-contents ranging from 0.63% to 1.06% in a deciduous forest near Munich (Germany ...

A transference principle for general groups and functional calculus on UMD spaces [PDF]

open access: yes, 2008
We prove a transference principle for general (i.e., not necessarily bounded) strongly continuous groups on Banach spaces. If the Banach space has the UMD property, the transference principle leads to estimates for the functional calculus of the group ...

Using an affinity analysis to identify phytoplankton associations

open access: yesEcology and Evolution, 2022
Phytoplankton functional traits can represent particular environmental conditions in complex aquatic ecosystems. Categorizing phytoplankton species into functional groups is challenging and time‐consuming, and requires high‐level expertise in species ...
