In this paper, we investigate the distributional properties of the estimated tangency portfolio (TP) weights assuming that the asset returns follow a matrix variate closed skew-normal distribution. We establish a stochastic representation of the linear combination of the estimated TP weights that fully characterizes its distribution. Using the stochastic representation we derive the mean and variaIn this paper, we investigate the distributional properties of the estimated tangency portfolio (TP) weights assuming that the asset returns follow a matrix variate closed skew-normal distribution.

This paper presents an overview of animals depicted within the Swedish con-cession area of Gebel el-Silsila and Shatt el-Rigal, spanning the Prehistoric to the early Islamic period. It includes commentaries on stylistic, technical and chronological phases of the rock art, and present an overview of distribution patterns as well as a relative taxonomic morphology for the more frequent motifs.

Inflation began to increase rapidly towards the end of 2021 and remained elevated throughout 2022. Higher energy prices contributed significantly to the increase in inflation. However, core-inflation, excluding the direct contribution of energy prices, was also significantly above the European Central Bank’s inflation target.

The final day of the conference opened with Albin Thörn Cleland’s presentation, “Hidden Choral Stimuli: The Role of Accent in Aristophanes’ Refrains”. His paper examined the interplay of pitch accent, metre and musical melody across metrically identical refrains in pre-Hellenistic Ancient Greek lyric poetry, an aspect that has long remained relatively obscure and misunderstood. Building on Conser

Wind-abraded cobbles (ventifacts) and aeolian sand are known from the sandy-gravelly coastal areas of south-western Sweden, especially in association with raised deltas. Ventifacts are recorded on at least two different stratigraphic levels, at some sites atop glaciofluvial sediment, at other sites atop littoral deposits, and in some places at both levels, while aeolian sand usually forms a surfic

At temperate latitudes, altricial birds and their nestlings need to handle night temperatures well below thermoneutrality during the breeding season. Thus, energy costs of thermoregulation might constrain nestling growth, and low nocturnal temperatures might require resources that parents could otherwise have invested into nestlings during the day. To manipulate parental work rate, we performed brAt temperate latitudes, altricial birds and their nestlings need to handle night temperatures well below thermoneutrality during the breeding season.

06-methylated guanine dinucleotides were used to study the influence of hydrogen bonding on the specific binding of the antitumor drug cDDP, cis-PtCl2(NH3)2, to DNA. In this interaction, the guanine-06 site appears to be important in explaining the preference for a pGpG-N7(1),N7(2) chelate, which results from H-bridge formation with the ammine ligand of cDDP.

Vägar är en onekligen central del i vårt globala samhälle. De betyder kontakt och förflyttning för oss, men för djuren är dem ofta hinder vilket kan leda till att habitat fragmenteras och att djur isoleras. När djuren isoleras kan de inte nå nya resurser eller nya habitat, eller hitta en partner. Detta kan innebära att djuren får sämre överlevnadschanser och svårare att fortplanta sig. I värsta faHabitat fragmentation is a common problem in relation with road infrastructure which leads to mortality, isolation of animal populations, and has a negative effect on biodiversity. Animal crossings have been implemented in many countries and are a useful tool to mitigate these problems but they are expensive to build. This thesis explores the methodological approaches used to evaluate how wildlife

The main focus of this Master Thesis is the development and evaluation of an actuation system that controls a variable compressor for the automotive industry. This variation allows the compressor to produce different boost pressures on demand. Before the development process could start a theoretical analysis of the different forces acting on the system were conducted. These analyses consisted of a

A number of methods for measuring moisture transport properties of cementitious materials were compared in a series of experiments. Two OPC mortars with two water-binder-ratios were wet cured for six months and used to produce specimens as discs with different thicknesses and diameters. The cup methods were easy to use, reliable and fairly rapid but need a stable, surrounding, CO2-free climate, ho
