Mljet (Latin: Melita) is eighth island in Croatia by size, one of the largest south Dalmatian islands and Dubrovnik archipelago’s largest island. Due to its beauty and living standard, the island of Mljet has a rich but insufficiently explored history. The remains of a Roman palace in Polače, according to which the place got its Slavicized name, bear witness of a strong Roman influence and the period of progress of the island of Mljet. The palace in Polače is certainly the most important Roman-period monument on the island. It was built as a villa rustica. Together with Diocletian’s Palace in Split, it represents the largest Roman monument on the entire territory of Dalmatia. The port in Polače is quite hidden and as such offered protection to ships and served as dilivery port for agricultural produce from the entire Roman empire. In the Roman period, this palace served as a headquarters of island’s governor, military, administration and clergy. All previous research suggest that this settlement  was inhabited from 1st to 11th century with all the features of an ancient and early  medieval town. Using previously analyzed sources and available literature, the paper tries to point out the importance and position of the island during the Roman  period. Particular attention was paid to the analysis of two legal acts - the charter of the German army chief and the barbarian king of Italy Odoacer, from the second  half of the 5th century and the fragment of the testament of an unknown testator  from the mid VI century, within which, in the period of a century, is mentioned the  same amount of yield (earnings) from the island of Mljet.

Approximate entropy (ApEn) and sample entropy (SampEn) have been previously used to quantify the regularity in centre of pressure (COP) time-series in different experimental groups and/or conditions. ApEn and SampEn are very sensitive to their input parameters: m (subseries length), r (tolerance) and N (data length). Yet, the effects of changing those parameters have been scarcely investigated in the analysis of COP time-series. This study aimed to investigate the effects of changing parameters m, r and N on ApEn and SampEn values in COP time-series, as well as the ability of these entropy measures to discriminate between groups. A public dataset of COP time-series was used. ApEn and SampEn were calculated for m = {2, 3, 4, 5}, r = {0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5} and N = {600, 1200} (30 and 60 s, respectively). Subjects were stratified in young adults (age < 60, n = 85), and older adults (age ≥ 60) with (n = 18) and without (n = 56) falls in the last year. The effects of changing parameters m, r and N on ApEn and SampEn were investigated with a three-way ANOVA. The ability of ApEn and SampEn to discriminate between groups was investigated with a mixed ANOVA (within-subject factors: m, r and N; between-subject factor: group). Specific combinations of m, r and N producing significant differences between groups were identified using the Tukey’s honest significant difference procedure. A significant three-way interaction between m, r and N confirmed the sensitivity of ApEn and SampEn to the input parameters. SampEn showed a higher consistency and ability to discriminate between groups than ApEn. Significant differences between groups were mostly observed in longer (N = 1200) COP time-series in the anterior-posterior direction. Those differences were observed for specific combinations of m and r, highlighting the importance of an adequate selection of input parameters. Future studies should favour SampEn over ApEn and longer time-series (≥ 60 s) over shorter ones (e.g. 30 s). The use of parameter combinations such as SampEn (m = {4, 5}, r = {0.25, 0.3, 0.35}) is recommended.

Studying the hazel flowering was carried out in agro-ecological conditions of the Banja Luka in the period from December to March during 2010/2011 and 2011/2012. The study was conducted on 13 hazel cultivars in two orchards. In the first orchard, the following four cultivars were observed: ‘Tankoljuskasti’, ‘Multiflora’, ‘Merveille de Bollwiller’and ‘Tonda Gentile Romana’, whilst the second orchard included the following: ‘Hall’s Giant’, ‘Gustav’s Zellernuss’, ‘Istrian Round’, ‘Avellana’, ‘Romai’, ‘Apolda’, ‘Ludolph’s Zellernuss’, ‘Imperiale de Trebizonde’and ‘Jean’s’. Phenological observations of the development of flowering phenophase with the aforementioned cultivars were monitored every three days in both years. In 2010/2011 the blooming of male and female inflorescence of the observed hazel cultivars lasted from late December to mid-March in total. The presence and pollen germination was proven to be a limiting factor for a successful pollination and fruit set in 2011. Namely, the pollen of cultivars: ‘Hall’s Giant’, ‘Istrian Round’, ‘Ludolph’s Zellernuss’, ‘Avellana’, ‘Imperiale de Trebizonde’ and ‘Romai’ did not germinate, and with ‘Gustav’s Zellernuss’, pollen germination was very low (7,22%). In ‘Apolda’, ‘Jean’s’, ‘Merveille de Bollwiller’, ‘Tonda Gentile Romana’, ‘Multiflora’ and ‘Tankoljuskasti’ pollen germination ranged between 28,57-81,69%. In 2011/2012 the flowering of male and female inflorescence of the observed hazel cultivars started 30 to 45 days later than the previous year i.e., female inflorescence of all the observed cultivars bloomed in early and mid-March, except in ‘Tankoljuskasti’, in which female inflorescence bloomed in late January and early February. Male inflorescence of ‘Tankoljuskasti’, ‘Hall’s Giant’ and ‘Gustav’s Zellernuss’ bloomed in the second half of January and early February, and in all other cultivars in mid-March. Pollen germination in 2012 proved to be a limiting factor for ‘Apolda’ and ‘Romai’, as their pollen did not germinate, as well as for ‘Hall’s Giant’ and ‘Jean’s’ where pollen germination was below 5%. For other cultivars, pollen germination was very good and ranged from 37,24 (‘Merveille de Bollwiller’) to 73,97% (‘Multiflora’). Based on the analysis of dynamics of blooming and pollen germination of 13 hazel cultivars in two years, the monitoring of pollen germination and strategy of artificial pollination must be adopted as a basic approach to control hazel fertility in the conditions of the Banja Luka region.

This paper is motivated by the control of robot teams by a human. Control challenges arise because i) typically, the team needs to achieve multiple control objectives, shared between the robot team and the human, in order to accomplish a task, ii) robust stability needs to be guaranteed to facilitate the safe interaction with the human and the apriori unknown environment. The concept of passivity has been successfully applied for robust stabilization of robotic systems, however, not in the context of shared control in human-robot team interaction. In this paper we propose a novel control approach which decouples the robot team dynamics into multiple subsystems, each having a different control objective. The proposed control law, suitable for the interaction of the robot team with the human or environment, guarantees passivity of the subsystems. The approach is illustrated in a simulation.

Abstract This paper aimed to investigate metaphorical images used by master’s students in order to gain an insight into their schemata for thinking about the process of master’s thesis writing. Semistructured interviews on the topic of master’s thesis writing with three students coming from humanities, social sciences and natural sciences served as a corpus from which the data were extracted. The paper analysed participants’ unconscious use of metaphorical language in their narratives, mirroring their perception of the thesis writing process. The results revealed that the participants’ personal experience revolves around the concept of journey as the central image they share and the journey metaphor, along with a group of related specific metaphors, serves to illustrate the complexity of the writing process itself.

Abstract This study estimates the present and future distribution potential of 12 thermophilic and rare tree species for Europe based on climate-soil sensitive species distribution models (SDMs), and compares them to the two major temperate and boreal tree species (Fagus sylvatica and Picea abies). We used European national forest inventory data with 1.3 million plots to predict the distribution of the 12 + 2 tree species in Europe today and under future warming scenarios of +2.9 and +4.5 °C. The SDMs that were used to calculate the distributions were in a first step only given climate variables for explanation. In a second step, deviations which could not be explained by the climate models were tested in an additional soil variable-based model. Site-index models were applied to the found species distribution to estimate the growth performance (site index) under the given climate. We find a northward shift of 461 km and 697 km for the thermophilic species over the regarded time period from 2060 to 2080 under a warming scenario of 2.9 °C and 4.5 °C, respectively. Potential winners of climatic warming have their distribution centroid below 48°N. Fagus sylvatica and Picea abies will lose great parts of their potential distribution range (approx. 55 and 60%, respectively). An index of area gain and growth performance revealed Ulmus laevis, Quercus rubra, Quercus cerris and Robinia pseudoacacia as interesting alternatives in managed temperate forests currently dominated by F. sylvatica and P. abies. The 12 investigated species are already in focus in forestry and it has been shown that the changing climate creates conditions for a targeted promotion in European forests. Nevertheless, area winners exhibited lower growth performances. So, forest conversion with these warm-adapted species goes hand in hand with loss of overall growth performance compared to current species composition. So, the results are a premise for a further discussion on the ecological consequences and the consistency with forest socio-economic goals and conservation policies.

The Paediatric Rheumatology European Society (PReS) has over many years, developed a portfolio of educational activities to address increasing educational needs of workforce and support young clinicians to acquire skills to develop new knowledge and deliver clinical care in the future. These educational activities aim to facilitate growth of paediatric rheumatology and ultimately improve the clinical care for children and families. This article describes the current portfolio of PReS educational activities and their relevance to the international paediatric rheumatology community.

Introduction: Epilepsy is a disease that affects more than 50 million people worldwide. This most common chronic neurological disorder, which actually represents impairment of some brain structures, makes the patients suffering from epilepsy victims of environmental stigma, which, due to ignorance, is considered them to be mentally ill. Aim: The aim of the study was to examine the demographic data of epilepsy patients, disease duration, frequency of seizures and type of therapy (mono/polytherapy), determine the existence of depressive symptomatology in patients with epilepsy and to examine predictive gender significance, degree of education, employment status, type of epileptic seizure on the presence of stigma. Patients and methods: The sample consisted of 100 respondents, both sexes, treated in the Epilepsy Outpatient Clinic of the Clinic for Neurology of the Clinical Center of the University of Sarajevo, selected randomly. All respondents fulfilled the Mini Mental Status Test. Patients who met the required score (27 and more of a total of 30) performed a test to evaluate the possible presence of depressive affective disorder with Back’s Depression Scale. They also responded to the questionnaire of the revised version of Epilepsy Stigma Scale. Results: The mean age of the respondents was 37.46±11.9 years. Men are on average older 40.84±11.9 years, than women 34.69±11.2 in the tested sample, and the difference shown is statistically significant, p=0.009. The difference in the frequency of respondents by status of employment is statistically significant, χc2=50.4; p=0.0001. According to Beck’s Depression Scale, a total of 15 respondents were without a stigma, a total of 51 respondents felt mild stigma, and 34 respondents felt high level of stigma, 18 of which (52.9%) with score ≤9, 2 (5.9%) score 10-15, 4 (11.8%) had a score of 16-19, 4 (11.8%) score of 20-29, while 6 (17.6%) had a score of ≥30. The degree of depression and the degree of stigma are in correlation, p=0.011. The time without epileptic seizures was approximately 6 (3-8) months for respondents without stigma, in respondents with mild stigma 4 (3-6) months and respondents with high stigma 6 (4-9) months. The mean time without epileptic seizures is statistically significantly different in relation to the degree of stigma, p=0.026 Conclusion: The results of this study showed that poor control of epileptic seizures and the presence of depression had a significant predictive value for the development of the stigma. Therefore, in addition to establishing good control over epileptic manifestations, it is extremely important to pay attention to psychological changes, to raise awareness in the community, to continuously carry out education, in order to have the best outcomes in treatment of a patient with epilepsy.
