Tools for climate change adaptation in water management - inventory and assessment of methods and tools
This report summarizes an inventory of methods and tools for assessing climate change impacts, vulnerability and adaptation options, focusing on the water sector. Two questions are central: What are the opportunities for international applications of Dutch methods and tools? And: Which methods and tools available abroad are suitable for application in The Netherlands
Antiproton-proton partial-wave analysis below 925 MeV/c
A partial-wave analysis of all antiproton-proton scattering data below 925
MeV/c antiproton laboratory momentum is presented. The method used is adapted
from the Nijmegen phase-shift analyses of pp and np scattering data. The
Nijmegen 1993 antiproton-proton database, consisting of 3646 antiproton-proton
scattering data, is presented and discussed. The best fit to this database
results in chi^2_min/Ndata = 1.043. The pseudovector coupling constant of the
charged pion to nucleons is determined to be (f_c)^2 = 0.0732(11) at the pion
pole, where the error is statistical.Comment: Report THEF-NYM 93.02 42 pages REVTeX, 7 separate postscript figures

FarmBot RFID Integration
The purpose of this project is to assist the company FarmBot improve their product by adding RFID tracking to the FarmBot robot. RFID tracking will allow the robot to select and pick up tool heads without any user interference
Partial-Wave Analyses of all Proton-Proton and Neutron-Proton Data Below 500 MeV
In 1993 the Nijmegen group published the results of energy-dependent
partial-wave analyses (PWAs) of the nucleon-nucleon (NN) scattering data for
laboratory kinetic energies below Tlab=350 MeV (PWA93). In this talk some
general aspects, but also the newest developments on the Nijmegen NN PWAs are
reported. We have almost finished a new energy-dependent PWA and will discuss
some typical aspects of this new PWA; where it differs from PWA93, but also
what future developments might be, or should be.Comment: Presentation at the 19th European Conference on Few-Body Problems in

The Status of the Pion-Nucleon Coupling Constant
A review is given of the various determinations of the different piNN
coupling constants in analyses of the low-energy pp, np, pbarp, and pi-p
scattering data. The most accurate determinations are in the energy-dependent
partial-wave analyses of the NN data. The recommended value is f^2 = 0.075 . A
recent determination of f^2 by the Uppsala group from backward np cross
sections is shown to be model dependent and inaccurate, and therefore
completely uninteresting. We also argue that an accurate determination of f^2
using pp forward dispersion relations is not a realistic option.Comment: 19 pages, latex2e with a4wide.sty, more information is available at

Deuteron Dipole Polarizabilities and Sum Rules
The scalar, vector, and tensor components of the (generalized) deuteron
electric polarizability are calculated, as well as their logarithmic
modifications. Several of these quantities arise in the treatment of the
nuclear corrections to the deuterium Lamb shift and the deuterium hyperfine
structure. A variety of second-generation potential models are used and a
(subjective) error is assigned to the calculations. The zero-range
approximation is used to analyze a subset of the results, and a simple
relativistic version of this approximation is developed.Comment: 14 pages, LaTex - submitted to Physical Review
Mechanisms and outcomes of Autonomous Sensory Meridian Response
People who experience autonomous sensory meridian response (ASMR) report a complex emotional response of calming, tingling sensations that originate around the crown of the head in response to a specific subset of somatosensory and/or audio-visual triggers. Recently, the authenticity of these experiences has been established. This thesis aimed to build on prior work to further characterise both state and trait ASMR in terms of classification, empathic abilities and electrophysiological neural correlates. In Chapter 1 a brief review of the current literature is described, followed by an introductory methodology chapter.
Chapter 3 introduces a novel data-driven tool that is able to capture both state and trait ASMR, whilst also identifying potential respondents who report experiencing ASMR but who would otherwise fail a follow-up confirmation (e.g., negative associated affect). Using this data-driven approach in respondent classification allows a more comprehensive profiling of how participants respond to ASMR stimuli. This raises the potential to better understand mechanisms and broader traits associated with sub-groups of ASMR-responders in the future.
I further unpack the relationship between ASMR and empathy in Chapter 4. Results show that ASMR responders perform better at tasks designed to measure emotion identification capabilities. These findings systematically delineate the relationship between ASMR and empathy and show the importance of investigating subcomponents of the empathic process in order to fully explain the nature of individual differences in empathic response.
In Chapter 5 I sought to provide source-level signatures of oscillatory changes induced by this phenomenon and investigate potential decay effects — oscillatory changes in the absence of self-reported ASMR. Altogether, I showed the robust changes in the patterns of dynamical brain oscillations associated with an ASMR tingling experience. Further, I demonstrated the longlasting effects of ASMR across a wide range of brain regions and oscillatory powers.
Together, I propose a neural model of ASMR based on the principles of stochastic resonance and synchronisation in Chapter 6. Using testable hypotheses, I hope this model builds on prior work and progresses our understanding of the neurological basis of ASMR and the role neural noise in sensory processing in general
