Complexity And Entanglement In Quantum Gravity
… model, a theory of near-extremal black hole microstates. We find that this complexity grows linearly for a time exponential in the entropy, modulo a caveat concerning global obstructions to the growth of the distance function along geodesics, which we do not rule out. This constitutes a …

Automated Detection And Quantification Of Pain Using Electroencephalography
… biomarker using EEG was developed using EEG microstates to evaluate their specificity to pain compared to rest and two non-rest conditions evoking similar responses. Multifractal analyses on the microstate sequence showed that microstate interactions during pain were significantly more stable …

Magnetochemische Analyse und Modellierung von d N -, 4f 7 - und 5f N -Systemen mit dem Computerprogramm CONDON
… by CONDON using of the full basis of microstates, whereby the magnetically relevant parameters are optimized. In summary, the computer program CONDON can be regarded as an excellent tool for the clarification of the magnetic properties of a plethora of metal complexes. This thesis …

A theoretical analysis of interstitial hydrogen : pressure-composition-temperature, chemical potential, enthalpy and entropy
… in terms of the change in its accessible microstates. A connection is also made between the entropy and electronic states of interstitial hydrogen. However, our model indicates that this connection is too small to account for experimental results. Therefore, a conclusion is made that the …

Spatial Organization of Multicellular Living Systems
… as a pair of quantities to define the local microstates of multicellular living systems. In chapter 3, we develop configurational fingerprints based on these local structures, and extract two parameters, namely the volumetric and shear order parameters, that are reflective of the transitions …

Pulsed out of awareness: EEG alpha oscillations represent a pulsed inhibition of ongoing cortical processing
… exerts its inhibitory role through alternating microstates of inhibition and excitation. Chapter 4 and Chapter 5 discuss evidence that this pulsed inhibition can be entrained to rhythmic stimuli in the environment, such that preferential processing occurs for stimuli at predictable moments, …

Investigation of the effect of hydroxycitric acid on urinary calcium oxalate risk factors for kidney stone formation in artificial urine: theoretical modelling and in vitro crystallisation experiments
… were too close to resolve and that several microstates were in rapid exchange. Similarly, for the metal complexes, several species were found to be in rapid exchange. Crystallisation experiments were conducted in artificial urine, to determine the effect of HCA on the thermodynamics and …

Fracture mechanics in the semigrand canonical ensemble
… generate a sufficiently large number of possible microstates in the semigrand canonical ensemble, and associated energy and bond fluctuations. The SGCMC approach permits identifying the full phase diagram of brittle fracture for harmonic and non-harmonic bond potentials, analogous to the …

Hangry Minds, Unhealthy Choices: EEG Microstate Dynamics as Predictors of Goal-Dependent Dietary Self-Control
… shorter average durations of dominant EEG microstates—reflecting more unstable neural dynamics—were associated with healthier food choices and greater goal-dependent regulatory success, captured in their ability to flexibly reduce taste considerations when health goals were activated. …

Tracking brain dynamics across transitions of consciousness
… methods of phase-lag brain connectivity and EEG microstates in a group of healthy subjects, a unique microstate is identified, whose increased duration predicts behavioural unresponsiveness to auditory stimuli during drowsiness. This microstate also uniquely captures an increase in frontoparietal …

Sorption in disordered porous media
… of the relative degeneracy (the number of microstates that have the same value of some macroscopic variables) in the systems that are too large to be handled exactly. The methods, based on a restricted infinite temperature sampling, obtain equidegenerate surfaces and the degeneracy gradient …

Soliton Scattering on Obstructions in Relativistic Theories
… transformation to smooth geometries describing microstates of the D1-D5-KK monopole system in type IIB supergravity compactified on a six-torus, and obtain solutions with an additional momentum charge. We study the supersymmetric and near-core limits of this construction.
