    الوصف: Each year Telehealth and Medicine Today reaches out to journal board members, annual ConV2X Symposium speakers and ecosystem subject matter experts to share their views and perspectives for the near term in the telehealth and virtual care marketplace. The article presents insights into where authors anticipate market opportunities and gaps that must be addressed for the most appropriate and effective patient care programs globally and regionally for 2022.

    الوصف: The recently discovered two‐dimensional oxide quasicrystal (OQC) derived from BaTiO 3 on Pt(111) is the first material in which a spontaneous formation of an aperiodic structure at the interface to a periodic support has been observed. Herein, we report in situ low‐energy electron microscopy (LEEM) studies on the fundamental processes involved in the OQC growth. The OQC formation proceeds in two steps via of an amorphous two‐dimensional wetting layer. At 1170 K the long‐range aperiodic order of the OQC develops. Annealing in O 2 induces the reverse process, the conversion of the OQC into BaTiO 3 islands and bare Pt(111), which has been monitored by in situ LEEM. A quantitative analysis of the temporal decay of the OQC shows that oxygen adsorption on bare Pt patches is the rate limiting step of this dewetting process. image

    الوصف: What does it take for warnings about violent conflict and war to be listened to, believed and acted upon? Why are warnings from some sources noticed and largely accepted, while others are ignored or disbelieved? These questions are central to considering the feasibility of preventing harm to the economic and security interests of states. Challenging conventional accounts that tend to blame decision-makers' lack of receptivity and political will, the authors offer a new theoretical framework explaining how distinct 'paths of persuasion' are shaped by a select number of factors, including conflict characteristics, political contexts, and source-recipient relations. This is the first study to systematically integrate persuasion attempts by analysts, diplomats and senior officials with those by journalists and NGO staff. Its ambitious comparative design encompasses three states (the US, UK, and Germany) and international organisations (the UN, EU, and OSCE) and looks in depth at four conflict cases: Rwanda (1994), Darfur (2003), Georgia (2008) and Ukraine (2014).

    الوصف: The northern regions are warming more rapidly than the global mean. This may cause problems in boreal forests if pest insects expand their ranges north. In Finland, the Nun moth (Lymantria monacha (Linnaeus)) is a potential forest defoliator that has earlier occurred sparsely along the southern coast of the country, but that might become a significant pest as it is in Central Europe. In this study we describe the changes in distribution and abundance of L. monacha in Finland, analyze these in relation to changing climate, and discuss management implications for the situation of a potentially serious pest expanding its range rapidly to new areas. We used data from two long-term databases, the open access Insect Database (1960–2013), and Nocturna (1993–2013), the national monitoring scheme for night-flying moths. A trend of rising L. monacha abundances in Southern Finland since the 1990s was discernible in both datasets. Furthermore we found that the species has expanded its range from the southern coast northwards to approx. 63 °N, i.e. about 200 km, during two decades. To compare the development of the L. monacha population with climatic variables we calculated three temperature parameters, EminT – the minimum temperature during the egg stage of L. monacha in winter, LT – the average temperature for the larval stage, and PAT – the average temperature for the pupal and adult stage. Model selection methods using information criteria ranked highest models where L. monacha abundance was related to EminT and PAT. This indicates that the recent success of L. monacha in Finland may be related to higher winter survival of eggs or improved dispersal and reproduction success of adult moths. The experimentally confirmed median freezing temperature of L. monacha eggs is −29.5 °C. Minimum winter temperatures on the southwestern coast of Finland have not dropped below this lethal limit since 1987. This corresponds temporally well the L. monacha upswing starting in the 1990s. Furthermore, it was notable that the temperature during the larval period (May – June) did not increase during the last decades, which suggests that high early summer temperatures have not been necessary for the northward expansion of L. monacha. L. monacha is a major pest in coniferous forests in Central Europe, and may become a threat throughout its expanded range. We outline a multilevel monitoring programme that has proven efficient in L. monacha outbreak areas, and advocate risk reduction through forest conversion to mixed and ecologically stable stands.
