—Longitudinal research is fundamentally important for understanding sustainable behavior change related to human health. This is particularly true for chronic illnesses, such as dementia and mental illness, where treatment is often measured in months and years over the long-term. For research on human-robot interaction (HRI) geared towards addressing such health-related issues, this presents a challenge in that many HRI studies (particularly in lab settings) are performed in a matter of minutes or at most hours. Given that reality, this suggests a need for innovative approaches to longitudinal research in HRI for such health-focused scenarios. Here, we argue that such methodological approaches to longitudinal HRI research should be grounded in existing models of behavior change (e.g. transtheoretical model) and leveraged via novel technology-enabled real-time sampling strategies for user activities outside of lab settings (e.g. ecological momentary assessment, EMA), all geared toward supporting data-driven methods for connecting robot behavior and human behavior over the long-term in in-the-wild settings.

Magnetic nanoparticles (MNPs) are widely used to facilitate magnetic particle imaging (MPI) which has the potential to become the leading diagnostic instrument for biomedical imaging. This comparative study assesses the effects of changing iron content and excitation frequency on point-spread function (PSF) representing the effect of magnetization reversal. PSF is quantified by features of interest for MPI: i.e. gradient amplitude and full-width-at-half-maximum (FWHM). A superparamagnetic quantifier (SPaQ) is used to assess differential magnetic susceptibility of two commercially available MNPs: Synomag ® -D50 and Synomag ® -D70. For both MNPs, the signal output depends on increase in drive field frequency and amount of iron oxide, which might be hampering the sensitivity of MPI systems that perform on higher frequencies. Nevertheless, there is a clear potential of Synomag ® -D for a stable MPI resolution, especially in case of 70 nm version, that is independent of either drive field frequency or amount of iron oxide.

Data acquisition in process industries usually takes place at each sampling. The disadvantage is that a considerable amount of data without new information about the state of the process is continuously transmitted and processed. This negatively affects the communication system and computational power, which is more critical nowadays given the number of variables measured, even in seconds. One solution concerns the event-driven paradigm, in which only relevant data according to a pre-defined criterion is forwarded for further processing. This work investigated the event-based threshold and delta methods in the context of fault detection. The data transmission rate was also analyzed. The well-know Tennessee Eastman problem (TEP) was used as a case study. The fault detection system was based on PCA (principal component analysis), which is widely used for this purpose in this benchmark. The results were compared with the commonly used time-based approach, for a fixed false alarm rate. The threshold rule provided similar results, but with much less data. For the delta rule, significant MDR (missed detection rate) gains of up to 74% were obtained for five of the six hard-to-detect faults, and of up to 69%, for two of the three very hard-to-detect faults. MDR values very close to zero were reached for two of the three intermediate detection faults and two of the hard-to-detect faults. The detection time was also evaluated. In this regard, considerably lower values were obtained for all intermediate detection faults, three of the hard-to-detect faults and all very hard-to-detect faults. In short, the delta method was able to improve fault detection performance, especially for hard-to-detect faults, with a considerably lower data transmission rate, around 20% on average. Event-driven data acquisition can be very attractive for process industries.

Figure 1. Our method obtains a high-quality 3D reconstruction from an RGB-D input sequence by training a multi-layer perceptron. In comparison to state-of-the-art methods like BundleFusion [3] or the theoretical NeRF [9] with additional depth constraints, our approach results in cleaner and more complete reconstructions. As can be seen, the pose optimization of our approach is key to resolving misalignment artifacts.

Serbian Sokol Societies were based on the idea of a new form of physical exercise originated in the Czech lands in the second half of the 19th century. After first initiatives, this idea soon spread to all Slavic as also countries where Slavic nations lived. That is how since 1907 this way of physical exercise appeared among Serbs who lived in America (USA). The Sokol idea in state of Pennsylvania started by the local Serbs in Steelton in the middle of 1912, when, following the initiative of the orthodox priest Teofil H. Stefanovic, they founded the Serbian Sokol Society. The subject of this research is Serbian Sokolism in America (USA) with the aim to explore when this society was founded, who took part in those and other activities until June 1914. During research authors used historical method.

A very important segment, which occurs as a result of welding, is the occurrence of residual stresses in welded structures. The effects of residual stresses can be beneficial or harmful to the structure, depending on their size, sign, and stress distribution in relation to the stresses caused by the external load itself. Therefore, the examination of residual stresses is very important because they significantly affect the formation and growth of cracks, the appearance of brittle fractures, material fatigue, etc. The paper presents the test procedure for measuring residual stresses by the method of "hole drilling" and the possibility of practical application of knowledge about residual stresses in order to improve the quality of machine parts and the structure itself.

The main objective of the research is to analyze the possibility of introducing the agro-ecological concept through appropriate agro-ecological measures in agricultural policy of Bosnia and Hercegovina. For this purpose, theoretical and empirical studies have been conducted. Theoretical research included analysis of the strategic and regulatory framework in the European Union and Bosnia and Hercegovina and analysis of the development of the concept of agro ecology. Empirical research has included surveying holders of agricultural holdings of subjects according to the Eco Stack project methodology. The survey results confirm that farmers are generally not familiar with the concept of agro ecology, but do apply some of the agro-environmental measures. On the basis of the research results, steps have been proposed to introduce a new model of support for the application of the agro-environmental concept and measures in the framework of agricultural policy of Bosnia and Hercegovina.
