Light-induced torque at multipolar plasmon resonance
… on the enhanced mechanical effects arising at multipolar plasmon resonance of a subwavelength plasmonic resonator. We perform Finite Difference Time Domain (FDTD) simulation and show that the discrete rotational symmetry of the resonator determines the possible output modes in angular momentum …

Exotic Phenomena Emerging from Localized Multipolar Degrees of Freedom
… for exotic macroscopic quantum phenomena. Multipolar moments, higher order generalizations of the familiar dipole, present a unique avenue for the discovery of a variety of exotic and novel phases of matter. These anisotropic charge and magnetization densities provide additional internal …

Fragmentation in International Financial Regulation: Rethinking Financial Regulation for a Multipolar World
International standard-setting bodies emerged as the central response to the intensification of cross-border activities. However, shortcomings in their design, the growing fragmentation of markets, and contextual changes – such as the US’ hostility towards multilateralism, the impacts of Brexit, …

Extracting Security from the Global South: Multipolar Control and Dependency in the Field of Critical Raw Materials
Οι κρίσιμες πρώτες ύλες (Critical Raw Materials – CRMs) έχουν μετατοπιστεί από ένα τεχνικό ζήτημα εφοδιασμού σε κεντρικό πεδίο οικονομικής στρατηγικής και πολιτικής ασφάλειας στο πλαίσιο της πράσινης και ψηφιακής μετάβασης. Η παρούσα διπλωματική εξετάζει πώς οι μεγάλες δυνάμεις επιδιώκουν να …

Mechanisms and Consequences of Chromosomal Instability in Malignant tumours
… and was also associated with the presence of multipolar mitoses. In contrast to cells having undergone anaphase bridging, daughter cells from these multipolar mitotic figures were observed not to form clones in culture, possibly because of the severe aneuploidy which is the result of …

Role of ICAM-1, a cell adhesion molecule, in morphological changes of BV2 microglial cell
… changes, from the round shape to bipolar or multipolar (spread) shape, according to time course. The treatment of LPS (1 ㎍/ml) influenced their morphological change at earlier time, no longer than 6 hrs. LPS treatment increased the numbers of cells into spread form with short and large …

Using Microscopy to Examine Mechanisms of Cell Division
… revealed that in cells depleted of TPX2, multipolar spindles formed by progressive spindle pole fragmentation. Consistent with structural role for TPX2 in the spindle, I found that while normal bipolar spindles resistant to collapse to monopolar spindles after inhibition of the mitotic …

Helical waves in Earth's outer core
… to a state of disorganised flow accompanied by a multipolar field. This transition is commonly termed the \emph{dipolar-multipolar} transition, and the collapse of the dipole occurs when the \emph{`local'} Rossby number \citep[as introduced by][]{christensen2006} is greater than $0.1$. Separately, …

Molecular Engineering of Dipolar and Octupolar Non-Linear Optical Materials for Next-Generation Telecommunications
… the author employed for charge density analyses. Multipolar modelling of experimental charge densities of the subject NLO materials forms an integral part of this thesis. Topological analysis is applied to these electronic structures, using the quantum theory of atoms in molecules (QTAIM), from …

Response of periodic systems to electromagnetic fields: multipole expansion, microscopic charge-current density, polarization and magnetization
… effects that arise due to higher order multipolar response. First, I evaluate the interaction constants that describe the collective radiative interactions between nanoparticles in magneto-electric quadrupolar arrays, in an approach that gives the radiative damping in an exact analytic …

The Role of Transcription Factors in Regulating Adult Neurogenesis after Excitotoxic Brain Injury
… Previous work identified SVZ-derived bipolar and multipolar cells within the lesioned striatum. I characterised and quantified migration and differentiation of retrovirally-labelled SVZ-derived green fluorescent protein (GFP) cells within the lesioned striatum. In addition to neuroblasts, …

The effect of spindle geometry on the establishment of merotelic kinetochore attachment and chromosome mis-segregation
… centrosomes, which lead to the assembly of multipolar spindles during early mitosis when attachments between kinetochores and microtubules are forming. Supernumerary centrosomes facilitate the formation of merotelic attachments, in which a single kinetochore binds microtubules from more than …

The Southern Strategy: the People's Republic of China and Its Operations in Latin America
The People's Republic of China strives for a multipolar world that is not dominated by the United States. An international arena no longer controlled by the United States could one day allow China greater freedom of action to fulfill its goals. In order to make the world more malleable to China's …

The People's Republic of China's Preeminent Power Ambitions: An Assessment of Its Maritime Efforts
… power in Asia and thus become a major power in a multipolar world. In contemporary history, lessons learned from the fall of the Soviet Union, the 1991 Gulf War, the war in Kosovo, and the revolution in military affairs have also affected China's evolving strategic and military doctrines Through a …

The Rise of China: Economic Expansion, Military Modification and the Belt and Road Initiative
… and geopolitics. I analyze China's vision of a multipolar world and how it contrasts with the current global order and how this fuels rivalry with the U.S. and other powers. China's rise is very controversial because this directly challenges the U.S.'s role as the dominant global power. The …

Multipole Symmetries and Many Body Physics
… studies the many body physics of systems with multipolar conservation laws --- systems which conserve both a total charge and various multipole moments thereof. These conservation laws place constraints on the way in which particles can move, and carry important ramifications for both quantum …
