Deficits on the Clock Drawing Test in Parkinson’s Disease

Parkinson’s Disease (PD) is a progressive neurodegenerative disorder that affects 1% of the world population over the age of 65—anywhere from four to six million people (National Parkinson Foundation, 2010). Although most people identify PD as a movement disorder, cognitive deficits are also present. Poor performance on tasks such as set shifting, internal control of attention, and sequencing is commonly reported by PD patients (Stout & Johnson, 2005), as are visual and verbal memory impairments (Moody, Bookheimer, Vanek, & Knowlton, 2004). Visuospatial skills are also problematic, including depth perception, spatial orientation, and spatial organization (Bowen, Burns, Brady, & Yahr, 1972)

Multilateral Economic Ties of Mongolia with its Asian Trading Partners in period of 2011-2021

This article gives insight of main aspects of Mongolian’s economy related to its Asian Trading Partners namely China, India, South Korea and Japan in period of 2011-2021. To give more clarity about the main trading partners of Mongolia there are two countries: China and Russia, but the author focuses only on the Asian trading partners. The main goal is to popularise still not well known economy of Mongolia and to see how it was developed in analysed period of 2011-2022. As the methodology of the research the author used empirical analysis based mainly on Macrobond data which also has access to Mongolian Statistics Office data and also to available world reports such OECD, UNCTAD. Besides that, the article was consulted with Mongolian Ambassador in Poland and it was enriched this way with his best knowledge regarding economy and Mongolia international trade and investment policy. The interesting aspect which was raised by the author in this article was the future state of economy of Mongolia after pandemic of SARSCoV-2 and impact of the restrictions imposed on Russia due to the war on Ukrain

Output Regulation for Systems on Matrix Lie-group

This paper deals with the problem of output regulation for systems defined on matrix Lie-Groups. Reference trajectories to be tracked are supposed to be generated by an exosystem, defined on the same Lie-Group of the controlled system, and only partial relative error measurements are supposed to be available. These measurements are assumed to be invariant and associated to a group action on a homogeneous space of the state space. In the spirit of the internal model principle the proposed control structure embeds a copy of the exosystem kinematic. This control problem is motivated by many real applications fields in aerospace, robotics, projective geometry, to name a few, in which systems are defined on matrix Lie-groups and references in the associated homogenous spaces
