1. 1. What difference does a week make? : An empirical analysis evaluating the effect of induction of labor in gestational week 41 among births in Sweden

   Master-uppsats, Uppsala universitet/Nationalekonomiska institutionen

   Författare :Angelica Eriksson; [2023]
   Nyckelord :Induction of labor; Quasi-experiment; Staggered treatment adoption; DiD imputation; QALY; Health economics;

   Sammanfattning : This thesis examines the relationship between gestational age and stillbirths, focusing on the effect of maternal age. Prolonged pregnancies have been associated with an increased risk of stillbirth, prompting the exploration of labor induction as a preventive measure. LÄS MER

3. 2. Exploratory analysis of immunological responses in wild and laboratory mice

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

   Författare :Ilia Alekseev; [2023]
   Nyckelord :;

   Sammanfattning : The use of mice as a model organism in biomedical research is widespread due to their similarities with humans in anatomy and physiology. However, the genetic isolation of inbred strains from natural populations raises concerns about the reliability of these models. LÄS MER

4. 3. Predicting Chronic Kidney Disease using a multimodal Machine Learning approach

   Magister-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Aakruti Mishra; Navaneeth Puthiyandi; [2023]
   Nyckelord :Chronic kidney disease; Multimodal approach; ROCKET; Random Forest; XGBoost; MIMIC-III database; Data imbalance; Temporal and static modalities; Soft voting;

   Sammanfattning : Chronic Kidney Disease (CKD) is a common and dangerous health condition that requires early detection and treatment to be effective. Current diagnostic methods are time-consuming and expensive. In this research, we hope to construct a predictive model for CKD utilizing a combination of time series and static variables for early detection of CKD. LÄS MER

5. 4. Iterative full-genome phasing and imputation using neural networks

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Människans evolution

   Författare :Lotta Rydin; [2022]
   Nyckelord :Machine learning; Genotype data; U-Net; Convolutional neural networks;

   Sammanfattning : In this project, a model based on a convolutional neural network have been developed with the aim of imputing missing genotype data. This model was based on an already existing autoencoder that was modified into a U-Net structure. The network was trained and used iteratively with the intention that the result would improve in each iteration. LÄS MER

7. 5. Imputing connections of random gene networks from time series data using ANNs

   Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

   Författare :Sofia Andersson; [2022]
   Nyckelord :artificial neural networks; ANNs; gene regulatory networks; GRNs; imputation; gene regulatory network imputation; GRN imputation; CNNs; convolutional neural network; randomly generated networks; ternary classification; binary classification; network inference; Physics and Astronomy;

   Sammanfattning : This thesis presents the architecture of a convolutional neural network which is trained to impute the connections of randomly generated gene regulatory networks under varying amounts of regularisation. The generated gene networks are simulated from 10 different starting conditions for each set of connections in order to obtain multiple time series. LÄS MER
