Novel Vascular‐Adaptive Liquid Metal Microspheres Enable Visualized Arterial Embolization Therapy
Advanced Science, EarlyView.We present drug‐loaded liquid metal microspheres (X‐MEN) as a novel agent for image‐guided arterial embolization. With inherent radiopacity and superior deformability, X‐MEN enables real‐time monitoring and conforms tightly to irregular vessels. This approach ensures precise, long‐lasting embolization without recanalization, addressing critical ...

Foreign exchange reserves in a credit constrained economy [PDF]
International Economics, 2012 cet article traite du rôle des réserves de change en tant qu’épargne de précaution dans un cadre de marché imparfait, dû à la présence de contraintes de crédit déterminées de façon endogène. nous montrons que le coût de détention des réserves est plus élevé en présence de contraintes sur le crédit, en raison de l’effet de levier de la dette ...

Bankarstvo, 2023 The research answered the question of what affects BH foreign exchange reserves and what is the lower limit of the optimal level of foreign exchange reserves of the Central Bank of Bosnia and Herzegovina (CBBH). We defined excess foreign exchange reserves as the difference between the balance of foreign exchange reserves and the lower limit of the ...

The Cost of Holding Foreign Exchange Reserves [PDF]
, 2020 Recent studies that have emphasized that the costs of accumulating reserves for self-insurance purposes have overlooked two potentially important side effects. First, the impact of the resulting lower spreads on the service costs of the stock of sovereign debt, which could substantially reduce the marginal cost of holding reserves. Second, when reserve
