A search is performed for localized excesses in the low-mass dijet invariant mass distribution, targeting a hypothetical new particle decaying into two jets and produced in association with either a high transverse momentum photon or a jet. The search uses the full Run 2 data sample from LHC proton-proton collisions collected by the ATLAS experiment at a center-of-mass energy of 13 TeV during 2015

The ALICE experiment was proposed in 1993, to study strongly-interacting matter at extreme energy densities and temperatures. This proposal entailed a comprehensive investigation of nuclear collisions at the LHC. Its physics programme initially focused on the determination of the properties of the quark–gluon plasma (QGP), a deconfined state of quarks and gluons, created in such collisions. The AL

Mechanisms of chemotherapy resistance in childhood cancer Cancer is a group of diseases in which cells start to divide uncontrollably, until they start to invade other tissues. Neuroblastoma is the third most common early childhood cancer. It develops in the sympathetic nervous system, and it is most often found in the adrenal gland. High-risk neuroblastoma is challenging to treat and has poor pr

MORC2 (Microorchidia CW type Zinc Finger protein 2) is a GHKL (gyrase, heat shock protein 90, histidine kinase, MutL) ATPase involved in chromatin remodeling and is highly conserved in eukaryotes. Mutations in the ATPase domain of MORC2 are known to cause neurodevelopmental disorders. MORC2 is recruited by the HUSH complex to target long, intronless transcription units such as LINE-1 retrotranspos

Cancer immunotherapy employs the patients' own immune system to eradicate the tumor. The success of immunotherapies largely depends on an immune cell population, called T cells. T cells have the capacity to differentiate between healthy and malignant cells based on mutations that are displayed on the surface of cancer cells. After recognition of the tumor cell, T cells induce killing. However,

This paper forms part of a broader study on the design of an unconventional, high speed, switched reluctance machine (SRM), for automotive traction applications making use of soft magnetic composite (SMC) material. The aim is to have this machine operate at a fundamental frequency of up to 4 kHz. Another characteristic is that switched reluctance machines tend to be operated in deep saturation a l

This article presents the first thermal experiments conducted on a novel cooling concept applied to a high speed switched reluctance machine topology for traction applications. By circulating the coolant in between the coils and the stator poles the winding and the stator iron are virtually thermally decoupled. A test motorette is used to demonstrate the potential of the cooling concept at current

This paper deals with the performance evaluation of a high speed axial flux switched reluctance motor for automotive traction applications. The motor makes use of a novel axial flux segmented rotor topology. The main aim of the design is to push the continuous power density as high as possible. The high speed nature of the design and the resulting high electrical frequency, as well as the machine

The purpose of this article is to describe and analyse the growth in food aid in Sweden, and how it affects the non-profit organisations providing it. The particular type of food aid in focus is large-scale collaborations between charitable non-profit organisations and the food industry, through which food surplus is turned into food aid for people in food insecurity. The first examples of such fo
