Background: Most current approaches in forest science and practice require information about structure and growth of individual trees rather than- or in addition to- sum and mean values of growth and yield at forest stand level as provided by classic experimental designs. By inventing the wheel design, Nelder provided the possibility to turn to the individual tree as basic information unit. such trials provide valuable insights into the dependency of growth on stand density at particular ***: Here, we present an extension of the original design and evaluation by Nelder.(i) We established Nelder wheels along an environmental gradient through Europe in atlantic climate in Belgium and Germany, Mediterranean climate in Italy, continental climate in Hungary as well as on high land climate in Mexico. such disjunct Nelder wheels along an environmental gradient can be regarded and analysed as a two-factor design with the factors of site condition and stand density.(ii) We present an advanced statistical approach to evaluate density dependent growth dynamics of trees planted in form of the Nelder design, which considers spatio-temporal autocorrelation.(iii)We prove the usefulness of the methods in improving ecological theory concerning density related productivity,trade-offs between facilitation and competition, and allometric relations between size ***: First evaluations based on remeasured Nelder wheels in oak(Quercus robur L.) show a size growth differentiation during the first observation period. In particular, height growth is accelerated under higher competition indicating facilitation effects. We detect furthermore a high variability in allometric ***: the proposed design, methods, and results are discussed regarding their impact on forest practice,model building, and ecological theory. We conclude that the extended Nelder approach is highly efficient in providing currently lacking individual tree level information.

Information schema constructs for defining warehouse databases of genotypes and phenotypes of system manifestation features

引用

Frontiers of Information Technology & Electronic Engineering 2016年第9期17卷 862-884页

作者： shahab POURTALEBI Imre horváth Faculty of Industrial Design Engineering Delft University of Technology

Our long-term objective is to develop a software toolbox for pre-embodiment design of complex and heterogeneous systems, such as cyber-physical systems. the novelty of this toolbox is that it uses system manifestation features(sMFs) for transdisciplinary modeling of these systems. the main challenges of implementation of the toolbox are functional design- and language-independent computational realization of the warehouses, and systematic development and management of the various evolving implements of sMFs(genotypes, phenotypes, and instances). therefore, an information schema construct(IsC) based approach is proposed to create the schemata of the associated warehouse databases and the above-mentioned sMF implements. IsCs logically arrange the data contents of sMFs in a set of relational tables of varying semantics. In this article we present the IsCs necessary for creation of genotypes and phenotypes. they increase the efficiency of the database development process and make the data relationships transparent. Our follow-up research focuses on the elaboration of the sMF instances based system modeling methodology.

In this paper we propose a method to construct probability measures on the space of convex bodies. For this purpose, first, we introduce the notion of thinness of a body. then we show the existence of a measure with the property that its pushforward by the thinness function is a probability measure of truncated normal distribution. Finally, we improve this method to find a measure satisfying some important properties in geometric measure theory.

Biological treatment of chicken feather waste for improved biogas production

A two-stage system was developed which combines the biological degradation of keratin-rich waste with the production of biogas. Chicken feather waste was treated biologically with a recombinant Bacillus megaterium strain showing keratinase activity prior to biogas production. Chopped, autoclaved chicken feathers （4%, W/V） were completely degraded, resulting in a yellowish fermentation broth with a level of 0.51 mg/mL soluble proteins after 8 days of cultivation of the recombinant strain. During the subsequent anaerobic batch digestion experiments, methane production of 0.35 Nm3/kg dry feathers （i.e., 0.4 Nm3/kg volatile solids of feathers）, corresponding to 80% of the theoretical value on proteins, was achieved from the feather hydrolyzates, independently of the pre- hydrolysis time period of 1, 2 or 8 days. Cultivation with a native keratinase producing strain, Bacillus licheniformis resulted in only 0.25 mg/mL soluble proteins in the feather hydrolyzate, which then was digested achieving a maximum accumulated methane production of 0.31 Nm3/kg dry feathers. Feather hydrolyzates treated with the wild type B. megaterium produced 0.21 Nm3 CH4/kg dry feathers as maximum yield.

systematic exploration of signal-based indicators for failure diagnosis in the context of cyber-physical systems

Malfunction or breakdown of certain mission critical systems(MCss) may cause losses of life, damage the environments, and/or lead to high costs. therefore, recognition of emerging failures and preventive maintenance are essential for reliable operation of MCss. there is a practical approach for identifying and forecasting failures based on the indicators obtained from real life processes. We aim to develop means for performing active failure diagnosis and forecasting based on monitoring statistical changes of generic signal features in the specific operation modes of the system. In this paper, we present a new approach for identifying emerging failures based on their manifestations in system signals. Our approach benefits from the dynamic management of the system operation modes and from simultaneous processing and characterization of multiple heterogeneous signal sources. It improves the reliability of failure diagnosis and forecasting by investigating system performance in various operation modes, includes reasoning about failures and forming of failures using a failure indicator matrix which is composed of statistical deviation of signal characteristics between normal and failed operations, and implements a failure indicator concept that can be used as a plug and play failure diagnosis and failure forecasting feature of cyber-physical systems. We demonstrate that our method can automate failure diagnosis in the MCss and lend the MCss to the development of decision support systems for preventive maintenance.

three research papers were published recently to compare the virological properties of the Omicron variant with the earlier variants of concern(VOC).1,2,3 the sARs-CoV-2 B.1.1.529 variant,Omicron,was first detected in south Africa in October 2021 and has spread rapidly;within three months,it appeared in more than 87 countries.4 During the surveillance of the epidemiological data and mutations of earlier COVID-19 variants and Omicron,significant differences were revealed mainly in the reproduction rate and hospitalization.

the use of consecutive feeding was applied to investigate the response of the microbial biomass to a second addition of substrates in terms of biodegradation using batch tests as a promising alternative to predict the behavior of the process. Anaerobic digestion（AD） of the slaughterhouse waste（sB） and its co-digestion with manure（M）, various crops（VC）, and municipal solid waste were evaluated. the results were then correlated to previous findings obtained by the authors for similar mixtures in batch and semi-continuous operation modes. AD of the sB failed showing total inhibition after a second feeding. Co-digestion of the sB ＋ M showed a significant improvement for all of the response variables investigated after the second feeding, while co-digestion of the sB ＋ VC resulted in a decline in all of these response variables. similar patterns were previously detected, during both the batch and the semi-continuous modes.
