The Light Dark Matter Experiment (LDMX) is a fixed target experiment that will search for dark matter, but is still in the development phase. An important aspect for the experiment is the discrimination of signal and background events. Here this signal and background discrimination is inspected using a machine learning technique called a Boosted Decision Tree (BDT). This is done using Monte Carlo
This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. The thesis focuses on pulse characterization, through use of frequency-resolved optical gating (FROG), of
Cerebral Palsy (CP) has an impact on muscles and movement. This happens due to brain damage before the age of two years. Either sometimes before birth, during childbirth or after birth. According to hjarnfonden.se, 200 children are added annually in Sweden with CP. People living with CP have these weaknesses for the rest of their lives. CP is not progressive disorder, that means brain damage can’
This report summarizes the classification systems for surface lining materials in Europe and Japan. There is also a part including a discussion on differences, similarities and possible ways to link the two different systems together. In June 1994, an important agreement was made between the member countries in the European Community. The agreement stated that all member countries should have the
The thesis deals with matters relating to neglected diseases and the lack of pharmaceutical R&D for the same diseases. Everybody is entitled to the right to health and subsequently the right to access to medicines, however not everyone has been receiving the benefits of this right. Currently there is an unsatisfying market-driven system, that can be changed by new and innovative approaches, su
With increasing migration to urban areas, Kenya is a country in change with new and challenging problems. Nairobi has a high population growth but a far from equal socio-economic development. As Nairobi continues to grow, so do the slum areas within the city and the slum Kibera has grown to be one of the largest in Africa. Due to the large economic differences within Nairobi I suggest that some pe
Floods and wildfires are two critical hazards that impose substantial direct and indirect costs to society, including the resource needs of rescue services. Their occurrence is strongly linked to meteorological conditions, playing a fundamental role in hazard development and assessment. These hazards are notably distinguishable due to opposing weather requirements, wet conditions for floods and dr
The formation and evolution of coastal dunes result from a complex interplay of eco-morphodynamic processes. State-of-the-art models can simulate aeolian transports and morphological dune evolution under certain conditions. However, a model combining these processes for coastal engineering applications was not yet available. This study aims to develop a predictive tool for dune development to info
Biochemical differences between sexes can also be seen in non-sexual organs and may affect organ functions and susceptibility to diseases. It has been shown that there are sex-biased visual perceptions and impairments. Abundance differences of eye proteins could provide explanations for some of these. Exploration of the ocular proteome was performed to find sex-based protein abundance differences
Suppose (f,X, μ) is a measure preserving dynamical system and φ: X → R a measurable function. Consider the maximum process Mn := max{X1, ,Xn}, where Xi = φ ○ fi-1 is a time series of observations on the system. Suppose that (un) is a non-decreasing sequence of real numbers, such that μ(X1 > un) → 0. For certain dynamical systems, we obtain a zero- one measure dichotomy for μ(Mn ≤ un i.o.) dependin
Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using 139 fb^{-1} of pp collision data at sqrt[s]=13 TeV with the ATLAS detector at the Large Hadron Collider. Searches targeting pure-wino chargino pair production, pure-wino chargino-neutralino production, or Higgsino production decaying via standard model W, Z, or h bosons are combine
Measured ice crystal concentrations in natural clouds at modest supercooling (temperature ~>−10°C) are often orders of magnitude greater than the number concentration of primary ice nucleating particles. Therefore, it has long been proposed that a secondary ice production process must exist that is able to rapidly enhance the number concentration of the ice population following initial primary ice
Deep learning has allowed for remarkable progress in many medical scenarios. Deep learning prediction models often require 105–107 examples. It is currently unknown whether deep learning can also enhance predictions of symptoms post-stroke in real-world samples of stroke patients that are often several magnitudes smaller. Such stroke outcome predictions however could be particularly instrumental i
Middle managers often find themselves in a challenging position: They have to impress different audiences in somewhat incompatible ways and represent and enact managerial ideals and expectations that may be detrimental to their work identities. This study explores role distancing as an alluring coping strategy. Role distancing – acts that express separateness between the individual and the enacted
International reference materials such as International Standard reagents facilitate quality assurance of essential biopharmaceutical products and related in vitro diagnostic tests. Standardization of antibody and DNA measurements and harmonization of laboratory procedures are key to the success of cancer prevention strategies through screening methods as well as for development and implementation
We compared the Q10 relationship for root-derived respiration (including respiration due to the root, external mycorrhizal mycelium and rhizosphere microorganisms) with that of mainly external ectomycorrhizal mycelium and that of bulk soil microorganisms without any roots present. This was studied in a microcosm consisting of an ectomycorrhizal Pinus muricata seedling growing in a sandy soil, and
OBJECTIVE: To evaluate the diagnostic potential of cerebrospinal fluid (CSF) levels of tau and beta-amyloid protein ending at amino acid 42 (Abeta42) as biomarkers for Alzheimer disease (AD) in clinical practice. DESIGN: A 1-year prospective study. SETTING: Community population-based sample of all consecutive patients admitted for investigation of cognitive symptoms to the Pitea River Valley Hospi
