De onstuitbare opmars van de N.V. Zuid-Korea

'Goud en Indianen' is een tijdens de reis bijgehouden journaal, met daarin opgenomen brieven over de communicatie tussen de schepen en de verhoren van gevangen genomen Spanjaarden en inheemse bevolking, die een uniek inzicht geven in het verloop van deze vrijwel onbekende expeditie.

Remco Breuker en Annette van Soest bespreken elke maand achtergronden bij het nieuws over Noord- en Zuid-Korea. Hoe machtig is Kim Jong-un nou echt? Zal Noord-Korea ooit zijn kernwapenarsenaal afbouwen? En hoeveel invloed hebben Zuid-Koreaanse multinationals op het Koreaanse schiereiland? Remco Breuker…

Technologische vooruitgang heeft impact op ons dagelijks leven. Ze zijn ook door regeringen ingezet om de grensbeveiliging te beheren, vooral bij controversiële grensovergangen. Hekken, hittesensoren, hittecamera’s, drones en andere hoogtechnologische apparatuur die momenteel worden getest, produceren…

The class-imbalance problem is a challenging classification task and is frequently encountered in real-world applications. Various techniques have been developed to improve the imbalanced classification performance theoretically and practically.

The thesis deals with the study of giant radio galaxies (GRGs), which are radio galaxies of megaparsec sizes.

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.

Neuraminidases are enzymes that cleave glycosidic linkages of sialic acid. These enzymes are involved in influenza infections as well as in many cellular processes in mammals and micro-organisms.

Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.

The interest of this thesis lies in spin transport in normal metals and superconducting half-metallic junctions.

Security is key to survival for any living organism: life is full of perils and threats, both physically, environmentally, and societally. Security challenges such as terrorism, natural disasters, and cybercrime rank among the most pressing issues of our time, affecting the security and safety of millions…

Zuid-Korea is hot and happening! Het land verovert de wereld met haar populaire cultuur: muziek, dans, mode, dramaseries, film en eten. Maar wat is de Korean Wave eigenlijk?

Van onderwijs tot een verrijkende ervaring

Wil je Oost-Azië echt begrijpen, dan kun je niet om Korea heen. Bij Koreastudies in Leiden ontdek je de fascinerende mengeling van eeuwenoude tradities en moderne leefgewoonten door de cultuur, geschiedenis en taal intensief te bestuderen.

The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

Het belangrijkste doel van dit onderzoek is om de steden van het Romeinse Nabije Oosten in de keizertijd in kaart te brengen, met een focus op locatie, stadsgrootte en stedelijke kenmerken, om de vorm van het stedelijke systeem en de niveaus van integratie te bestuderen.

Corruption, integrity (or a lack thereof…) and public values are near omnipresent elements in public administration and politics of all times. Cases of corrupt public officials and politicians continuously emerge. Strangely enough, however, it often remains unknown what actually occurred, how something…

IoT technology poses serval opportunities to supply chains. This thesis employs grey correlation and forecasting models, system dynamics, agent-based modeling, and ex-ante LCA to investigate and quantify the opportunities and risks of IoT-enabled sustainable supply chain operations from both industrial…

In previous studies at our laboratory it was demonstrated that drug exposure of HepG2 cells can lead to an altered TNFα-induced NF-κB oscillatory phenotype, concurrent with a synergistically increased sensitivity for TNFα-induced apoptosis.

There is an increasing amount of attention on EU and its Member States contributions to implementation of two landmark agreements: the Paris Climate Agreement and the UN Agenda 2030 with Sustainable Development Goals (SDGs). Absent from the current literature is an analysis of the political effect of…

The largest genus within the Phyllanthaceae family is a group called Phyllanthus L. Recent studies have shown, that Phyllanthus is paraphyletic with the genera Glochidion, Breynia and Synostemon nested within it.

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

This thesis advances automata learning, a key area in computer science, with applications in software verification, biological analysis, and autonomous technologies. It explores three main themes: first, it introduces a passive learning algorithm for generating compact probabilistic models from positive…
