  1. 1. The Impact of Targeted Memory Reactivation on Declarative Memory During Slow-Wave Sleep : A Systematic Review

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Julia Lundgren; [2023]
    Keywords : targeted memory reactivation; TMR; sleep; slow-wave sleep; SWS;

    Abstract : The method targeted memory reactivation (TMR) uses specific stimulation when subjects are completing tasks and during sleep. The TMR process is known to influence the consolidation of declarative memories. The aim of this thesis is to conduct a systematic review on the effects of TMR on declarative memory consolidation during slow-wave sleep (SWS). READ MORE

  3. 2. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Author : Qianhui Liu; [2022]
    Keywords : Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Abstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  4. 3. Koopman mode analysis of the side-by-side cylinder wake

    University essay from KTH/Mekanik

    Author : Jimmy Röjsel; [2017]
    Keywords : Bluff body; wake flow; Side-by-side cylinder wake; Flip-op instability; Modal analysis; Koopman operator; Koopman mode decomposition;

    Abstract : In many situations, fluid flows can exhibit a wide range of temporal and spatial phenomena. It has become common to extract physically important features, called modes, as a first step in the analysis of flows with high complexity. READ MORE

  5. 4. Catch the dream Wave : Propagation of Cortical Slow Oscillation to the Striatum in anaesthetised mice

    University essay from KTH/Beräkningsbiologi, CB

    Author : Tiago Ferreira; [2014]
    Keywords : Cortex; Striatum; anaesthesia; slow oscillation; spontaneous activity; ketamine; in vivo; up states; wavelet; MUA; high-gamma range; MSNs;

    Abstract : Under anaesthesia or in deep sleep, different parts of the brain have a distinctive slow oscillatory activity, characterised by states of high membrane potential and intensive spiking activity, the Up-states; followed by hyperpolarisation and quiescence, the Down-states. This activity has been previously described in vitro and in vivo in the cortex and the striatum, across several species. READ MORE

  6. 5. "Imaging with CBCT and 4D-CT of objects moving with respiratory motions"

    University essay from Medicinsk strålningsfysik (tills m KI); Fysikum

    Author : Elias Lindbäck; [2012]
    Keywords : Medical Physicist; Radiotherapy; SBRT; CBCT; 4D-CT; Sjukhusfysik; Strålbehandling; SBRT; CBCT; 4D-CT;

    Abstract : AB S TRACT purpose : To further investigate the effects of respiratory motions on CBCT imaging, as well as 4D-CT examinations, with a future goal of using obtained results to implement new methods for individual margins and daily matching procedures into routine clinical practice. background : Since the implementation of CBCT combined with modern accelerators, a higher degree of accuracy has been made possible in RT.
