1. Brain dynamics underlying preserved cycling ability in patients with Parkinson’s disease and freezing of gaitTeja Ličen, Martin Rakuša, Nicolaas I. Bohnen, Paolo Manganotti, Uroš Marušič, 2022, pregledni znanstveni članek Opis: Parkinson’s disease (PD) is generally associated with abnormally increased beta band oscillations in the cortico-basal ganglia loop during walking. PD patients with freezing of gait (FOG) exhibit a more distinct, prolonged narrow band of beta oscillations that are locked to the initiation of movement at ∼18 Hz. Upon initiation of cycling movements, this oscillation has been reported to be weaker and rather brief in duration. Due to the suppression of the overall beta band power during cycling and its continuous nature of the movement, cycling is considered to be less demanding for cortical networks compared to walking, including reduced need for sensorimotor processing, and thus unimpaired continuous cycling motion. Furthermore, cycling has been considered one of the most efficient non-pharmacological therapies with an influence on the subthalamic nucleus (STN) beta rhythms implicative of the deep brain stimulation effects. In the current review, we provide an overview of the currently available studies and discuss the underlying mechanism of preserved cycling ability in relation to the FOG in PD patients. The mechanisms are presented in detail using a graphical scheme comparing cortical oscillations during walking and cycling in PD.

2. Digital twin in sport: from an idea to realizationLuka Lukač, Iztok Fister, Iztok Fister, 2022, izvirni znanstveni članek Opis: A digital twin is a virtual model to reflect a physical object and helps it by making proper decisions. The decision-making process is based on the same input data that the simulated physical object has access to. Due to exploiting artificial intelligence, the decision-making process of the digital twin is more sophisticated than that of the physical object. In this study, the digital twin is applied to the sports training domain, where it addresses those questions that have arisen during the implementation of interval cycling training sessions. Thus, the digital twin runs on a mobile device (i.e., the Raspberry Pi platform), with which a cycle is equipped and demonstrates user-friendliness, robustness, reliability, and accuracy. The interval training sessions are transferred to the mobile device in the form of the domain-specific language EasyTrain, ensuring higher expressive power and ease of use. During the implementation, the digital twin advises the athlete with predicted information obtained by a sophisticated prediction model via a screen. The results of a huge experimental work showed that the difference in the average efficiency of the interval training implementation between the two cyclists that performed the experiments is prominent, as the efficiency of the professional training surpassed 90%, while the amateur training efficiency barely achieved 70%.

3. Assessment of the innovation system in SMEs using innovation taxonomy and pondering methods : diplomsko delo univerzitetnega študijskega programa I. stopnjeAna Gallardo Gandarillas, 2021, diplomsko delo Opis: In this bachelor thesis, the different types of innovation within a company are studied and analysed. The companies studied are SMEs i.e. from 10 to 250 employees. Smaller companies are mainly confronted with the problem of resources and larger companies with their strategic orientation. We have studied the ten types of innovations according to Doblin (Doblin 2014), and we realise that they have a rather marketing-oriented focus, so we analyse five groups of innovations that we consider to be the key (marketing, product, organisational, business model and technological innovation). Five groups of innovations have been weighed on a scale from 0 to 100 % according to their importance to contribute to the economic success of the company. All groups have been weighted and ranked in order of priority to initiate the innovation process in the SME, starting with marketing, followed by product, technological, organisational and business model innovations. We found innovation process needs to be implemented as a continuous cyclical process. If the company wants to be successful, it is a continuous cycle model, which should never stop. Once a particular innovation is chosen, it will be studied and tested whether the investment can be successful. If so investment process will be executed, if not, the cycling process will start again until gives a positive result. This way one of the innovation is recognized as most important according to circumstances in SME involved at a certain moment.

4. Equivalences in biological and economical systems : peloton dynamics and the rebound effectHugh Trenchard, Matjaž Perc, 2016, izvirni znanstveni članek Opis: An interdisciplinary bridge is proposed between principles of collective behavior in biological systems, particularly bicycle pelotons, and the economic phenomenon called the rebound effect. Two main equivalencies are proposed between aspects of peloton dynamics and aspects of energy service efficiencies and the rebound effect. Firstly, a threshold whereby weaker cyclists, up to maximal capacities, sustain speeds of pacesetters by drafting; equivalent to a threshold whereby consumers will not exceed maximum allocated budgets for energy services, costs for which are externally determined. Secondly, a threshold of peloton dynamics whereby, below this threshold, weaker cyclists share costly non-drafting positions, whereas above this threshold cyclists cannot share these positions but can sustain pacesetter speeds. This is in turn equivalent to the threshold in the context of energy service efficiency, whereby consumers will increase spending to the limit indicated by the rebound magnitude but not to their maximum allocated budgets. These thresholds are a consequence of the model equations, and the latter threshold is explained by consumer apprehension that existing energy efficiencies could disappear or be negative, when consumers would be over budget. This partly explains long term rebound increase, whereby consumers increase consumption as confidence rises that cost savings due to energy service efficiency is stable.
