Maciej Wódkiewicz* The soil seed bank and seed germination capacity of Poa annua in the vicinity of the Polish Halina Galera* Antarctic Station (South Shetlands, Antarctica) were investigated. It was documented that Katarzyna J. Chwedorzewska† annual bluegrass can reproduce sexually and produce a functional seed bank of close to Irena Giełwanowska‡ and 5000 seeds/m under maritime Antarctic cond...

Background and purpose - The number of patients where shoulder hemiarthroplasty (SHA) is an option is still substantial. Descriptive analyses performed by the Swedish Shoulder Arthroplasty Registry (SSAR) showed that while patients receiving SHA designs, i.e. resurfacing hemi (RH) and stemmed hemi (SH), reported similar shoulder functionality and quality of life, the revision rate for RH (12%) ...

This work presents a variation of Naor’s strategic observable model (1969), by adding a component of customer heterogeneity induced by the location of customers in relation to the server. Accordingly, customers incur a “travel cost” which depends linearly on the distance of the customer from the server. The arrival of customers with distances less than x is assumed to be a Poisson process with ...

Orexin A and B are hypothalamic peptides involved in the control of food intake, sleep patterns, autonomic and neuroendocrine systems. The biological actions of orexins are mediated via two G-protein coupled receptors, termed orexin receptor 1 (OX1R) and orexin receptor 2 (OX2R). The present study analyzed mRNA and protein expressions of OX1R and OX2R in porcine hypothalamic structures engaged ...

Bitcoin and its underlying blockchain mechanism have been attracting much attention. One of their core innovations, Proof-of-Work (PoW), is notoriously inefficient which potentially motivates a centralization of computing power, defeating the original goal of decentralization. Proof-of-Stake (PoS) is later proposed to replace PoW. However, both PoW and PoS have different inherent advantages and...

Soft breakdown properties a€ected by photon energy during rapid thermal post-oxidation annealing (POA) of ultrathin gate oxide are investigated. Generally, breakdown can be classi®ed into normal hard breakdown (HBD) and soft breakdown (SBD). It was found that the occurrence of HBD and SBD depends on the process and stress ®eld. Samples with front and back sides illuminated by a tungsten±halogen...

Although the utility of analyzing behavioral experience effects on neural cytochrome oxidase (CO) activity is well recognized, the behavioral correlates of endogenous differences in CO activity have rarely been explored. In male leopard geckos (Eublepharis macularius), the incubation temperature experienced during embryogenesis (IncT) and age affect CO activity in the preoptic area (POA), an ar...

We consider the problem of designing network costsharing protocols with good equilibria under uncertainty. The underlying game is a multicast game in a rooted undirected graph with nonnegative edge costs. A set of k terminal vertices or players need to establish connectivity with the root. The social optimum is the Minimum Steiner Tree. We are interested in situations where the designer has inc...

In recent decades, most methods proposed for radiometric slope correction involved the backscattering intensity values in synthetic aperture radar (SAR) data. However, these methods are not fully applicable to quad-polarimetric SAR (PolSAR) matrix data. In this paper, we propose a three-step semi-empirical radiometric terrain correction approach for PolSAR forest area data. The three steps of t...
