A radiation detection system combining a single-sided silicon strip detector (SSSD) and a high-purity germanium (HPGe) COMPEX detector module together with its anti-Compton shield (ACS) was set up at Lund University for environmental sample measurements. This system enables high sensitivity ––-coincidence analysis, enhancing the identification level of radionuclides in environmental samples. A com
Purpose: High-risk colon cancer may benefit from preoperative chemotherapy (preCHT), but evidence on its short-term safety and outcome is limited. Population-based evidence before its incorporation into national guidelines is lacking. Methods: Patients with final weighted stage II–III colon cancer undergoing elective resection between 2007 and 2017 were identified in the Swedish Colorectal Cancer
Closed-form conditions for bound states in the continuum are derived for planar, cylindrical, and spherical cavities enclosed by metasurfaces with electric and magnetic response. While the combined response in lossless systems enables field confinement in arbitrarily small cavities, the gain-enabled bound states in the continuum are found to coalesce with a laser mode, leading to intriguing single
Given the increasing number of heterogeneous data stored in relational databases, file systems or cloud environment, it needs to be easily accessed and semantically connected for further data analytic. The potential of data federation is largely untapped, this paper presents an interactive data federation system (https://vimeo.com/319473546) by applying large-scale techniques including heterogeneo
This ESMO CPG provides key recommendations and algorithms for managing DLBCL, FL, HL, MCL, MZL, PCNSL and PTCL. •It covers epidemiology, diagnosis, staging, risk assessment, treatment of primary and refractory disease and follow-up. •Treatment algorithms for each lymphoma type are provided. •The author group encompasses a multidisciplinary group of experts from different institutions and countries
Objective: The aim of this study was to explore experiences and challenges in handling feedback and criticism among early career surgeons. Design: This study is part of a prospective, exploratory, longitudinal study evaluating surgical residents throughout residency. Semi-structured interviews were conducted with medical doctors applying to a locum or residency position in a surgical specialty. An
The rapid growth of smart logistics, driven by IoT devices and data-intensive applications, necessitates secure, scalable, and efficient computing frameworks. As the edge-fog-cloud (EFC) paradigm supports real-time data processing, it faces significant security threats and attacks, including privacy risks, data breaches, and unauthorized access. To address these security threats and attacks, block
The advent of AlphaFold and consumer large language models have elicited unprecedented development of artificial intelligence (AI). AI has had substantial impact in every area of research, including in molecular biology. This is principally in thanks to contributions to the Protein Data Bank and various genome sequence databases, providing an astronomical amount of data for model training. These d
Alzheimer’s disease (AD) is the most common neurodegenerative disorder, affecting millions worldwide. The clinical presentation of AD is heterogenous and often complicated by the presence of multiple co-pathologies, which can overlap with features of other neurodegenerative disorders, underscoring the need for tools to aid accurate and timely diagnosis. Biomarkers for AD span multiple modalities a
Background and purpose: Neuroblastoma is the most common extracranial solid tumour in children. Radiotherapy is commonly part of the multimodal treatment for high-risk patients. The aim of this study is to analyse doses to organs at risk (OAR) in comparative proton and photon treatment plans for children treated for neuroblastoma and report side effects. Patient/material and methods: All children
Populärvetenskaplig sammanfattning Supramolekylär kemi är en relativt ny gren av kemin som involverar stora kemiska strukturer/enheter. Ett exempel på en ”supramolekyl” man dagligdags träffar på är klorofyll. Klorofyll (Figur 1 till vänster) består av en metall (magnesium) och en större kolvätestruktur som kallas porfyrin. Porfyriner finns i många olika varianter och används ofta i olika biologiskDuring the time range of this project, various compounds were synthesized. All of them will be used to synthesize the final compounds 2 and 3. Consequently, the compounds will build up a supramolecular cavity, which will be used to study a catalytic epoxidation of olefins. The aim of the project was furthermore to gain experience in laboratory work.

Alfa Laval has been using its unique adhesive mixture for over 50 years for bonding of rubber gaskets to the corrugated plates used in their heat exchangers. The adhesive mix is designated GC6 and is composed out of an epoxy component and a phenolic component. GC6 has throughout the years shown exceptionally good performance in both adhesion to the rubber gasket and to the plate with minimal pre-t
Denna rapport innehåller en produktutvecklingsprocess som fokuserar på att integrera ett mjukstängningssystem för skjutdörrar i ett existerande skåp på IKEA. Enheten har idag vad som kallas för guider som håller skåpsdörrarna på plats. Målet är att skapa en enhet som besitter de viktigaste egenskaperna av en guide och av en mjukstängningsmekanism för att kunna ersätta den förstnämnda. Detta görs fThis master thesis includes a product development process focused on incorporating a soft closing system for sliding doors in an existing cabinet at IKEA. A soft closing system prevents the door from slamming into the furniture when closing it. The unit today has what is called guides, holding the cabinet doors in place. The aim is to create a device that possesses all of the crucial qualities of
We consider a technique involving Neural Networks in order to try to predict trends for cryptocurrencies such as Bitcoin, Ethereum etc. In that respect the project involves construction, design and training of a deep learning Neural Network based on historical trading data for these cryptocurrencies. Subsequently we apply this trained network in order to better understand its ability to possibly f
To optimize precision and accuracy of small dispensed volumes, a dispenser was built. A 96-well plate was loaded with four replicates of a linear pyranine dilution series to test the accuracy and precision of the dispenser machine. Three dilution series of pyranine (100-0 percent, 10-0 percent and 1-0 percent) were made. The results showed that the dispenser has very good accuracy and precision. T
