The determined λ1 and λ5 values differed noticeably from the ICRP values, whereas the λ4 value was comparable to that of the ICRP. Compared with the ICRP reference model, the Korean model, in which the Korean-specific transfer coefficients were adopted, predicted noticeably lower thyroidal uptake and faster decrease of thyroidal iodine. In addition, the predicted cumulative activities of radioiodine in the thyroid were substantially lower (40 to 80 %) than those predicted by the ICRP model. The Korean model developed in this study demonstrates that the iodine biokinetics for Koreans (i.e. high-iodine-consuming population) obviously differ from that predicted by the ICRP model. Hence, the Korean model may serve to improve the accuracy of thyroid dose estimation for Koreans and will lead to practical changes in matters concerned with radiological protection.

The main objective of this research is to record both sensory and motor information from the ascending and descending tracts within the spinal cord for decoding the hindlimb kinematics during walking on the treadmill.

Two different experimental paradigms (i.e., active and passive) were used in the current study. During active experiments, five cats were trained to walk bipedally while their hands kept on the front frame of the treadmill for balance or to walk quadrupedally. Dihydromyricetin During passive experiments, the limb was passively moved by the experimenter. Local field potential (LFP) activity was recorded using a microwire array implanted in the dorsal column (DC) and lateral column (LC) of the L3-L4 spinal segments. The amplitude and frequency components of the LFP formed the feature set and the elastic net regularization was used to decode the hindlimb joint angles.

The results show that there is no significant difference between the information content of the signals recorded from the DC and LC regions durhe movement and ascending neural signals as the feedback information for control of the movement.In order to examine what lessons radiological emergency management may offer to the Covid-19 pandemic management and vice versa, a series of three online webinars were conducted with leading experts, scholars and practitioners from a wide range of disciplines essential for emergency management and long-term risk governance. The first webinar debated the lessons we are learning from the Covid-19 pandemic for radiological risk communication, the second explored issues around longer-term outcomes of a crisis and how to balance these with short-term actions whilst the third focused on the key challenges of the ‘transition phase’, using learning from Chernobyl (1986) and Fukushima Daichii (2011) accidents. This paper reviews the discussion and provides valuable lessons for the radiation protection community. Results of the discussion indicated that i) non-radiological and non-epidemiological consequences of emergencies, e.g. psychological (mental health), societal and economic, should not be underestimated; ii) multidisciplinary expertise is imperative for communication efforts and for effective emergency management, including decision-making in the application of protective measures; iii) stakeholder engagement, including the involvement of the potentially affected population, should be encouraged from an early stage and iv) trust is increased if policy-makers and main science agencies show a unified voice.

The aim of this study was to solve one of the current limitations for the characterization of the brain network in the Alzheimer’s disease (AD) continuum. Nowadays, frequency-dependent approaches have reached contradictory results depending on the frequency band under study, tangling the possible clinical interpretations.

To overcome this issue, we proposed a new method to build multiplex networks based on canonical correlation analysis (CCA). Our method determines two basis vectors using the source and electrodelevel frequency-specific network parameters for a reference group, and then project the results for the rest of the groups into these hyperplanes to make them comparable. It was applied to (i) synthetic signals generated with a Kuramoto-based model; and (ii) a resting-state EEG database formed by recordings from 51 cognitively healthy controls, 51 mild cognitive impairment subjects, 51 mild AD patients, 50 moderate AD patients, and 50 severe AD patients.

Our results using synthetic signals showeng the limitations of possible frequency-specific conflicts. Additionally, our method supposes a novel approach for the construction and analysis of multiplex networks during AD continuum.The article summarizes the data on the number of conversion therapy legal bans aimed at changing sexual orientation and gender identity in countries around the globe; the content and the form of such prohibitions, the scope of their action by territorial criterion and the nature of the prohibition itself are analyzed; the draft laws, which are intended to legalize such bans in the national and territorial regime are studied; the thematic case law of individual countries is partly examined; countries where conversion therapy is promoted and explicitly authorized by public authorities are considered. According to the results of the study of more than half a hundred legal documents, the information obtained is distributed and organized into the following categories national and regional prohibition of conversion therapy, direct and non-direct prohibition of conversion therapy; ban in different parts of the world. The content highlights the characteristics of the existing prohibitions, such as the name of the delict; year of entry into force of the relevant legal act; prohibition of sexual orientation and/or gender identity activities; the circle of persons subjected to the prohibition; the circle of persons protected by the prohibition; peculiarities. The results of the study showed that there are currently 15 countries in the world (14 United Nations and 1 outside the United Nations) where conversion therapy is prohibited. Among them 5 countries have direct nationwide bans; 6 countries have non-direct nationwide bans; 3 countries have direct regional bans; 1 country has an non-direct regional ban. Conversion therapy is prohibited in 6 countries in the Americas; 1 Asian country; 4 European countries; 4 Oceania countries.
