The spin polarization in centrosymmetric molybdenum disulfide (MoS2) bulk crystal is recorded by helicity dependent photocurrent exposed as elliptically polarized terahertz (THz) emission. We assign this observation to hidden spin polarization due to the local Dresselhaus effect induced by the molybdenum atomic site asymmetry. This spin polarization induces ultrafast optically controlled circular
We present a framework for measurement dimension reduction in Gaussian filtering, defined in terms of a linear operator acting on the measurement vector. This operator is optimized to minimize the Cramér-Rao bound of the estimate's mean squared error (MSE), yielding a measurement subspace from which elements minimally worsen the filter MSE performance, as compared to filtering with the original me
Ultra-reliable, low-latency communication (URLLC) is being developed to support critical control applications over wireless networks. Exploiting spatial diversity through relays is a promising technique for achieving the stringent requirements of URLLC, but coordinating relays reliably and with low overhead is a challenge. Adaptive relay selection techniques have been proposed as a way to simplify
We study the propagation and diffusion of electric charge fluctuations in the Bjorken hydrodynamic model with both white and Catteneo noise using purely numerical methods. We show that a lattice of noise fluctuations is required to fully calculate the two-point correlators of charge. We introduce a numerical procedure to solve the stochastic differential equations that arise from the charge conser
Finding life on a planet other than the Earth would easily be one of the greatest discoveries of all time, particularly so if it is found outside our Solar System. To do so, we must understand the conditions required for life to emerge and develop. Whilst an enormous amount of research has gone into understanding the requirements for life on Earth to have spontaneously arisen and then evolved, muc
The paper will present preliminary findings of my ongoing PhD thesis. The thesis aims atexploring the interplay of spatial and social life of migrants in public spaces and how thisrelates to the construction of relational, multiple, flexible, multi-scalar places of belonging.The thesis investigates how migrants, through the transgression of new territories, producenew meanings between the home cou
Manufacturing of biopharmaceuticals is a costly and time consuming process due to its inherent complexity and variability. The downstream process is the most expensive part and it involves multiple non-trivial steps. Continuous integrated manufacturing is a new concept that is encouraged by authorities. The advantages include uninterrupted operation, automation, consistent product quality, lower rManufacturing of biopharmaceuticals is a costly and time consuming process due to its inherent complexity and variability.

We investigated the change in terminus position between 1985 and 2015 of 17 marine-terminating glaciers that drain into Disko and Uummannaq Bays, West Greenland, by manually digitizing over 5000 individual frontal positions from over 1200 Landsat images. We find that 15 of 17 glacier termini retreated over the study period, with ~80% of this retreat occurring since 2000. Increased frequency of Lan
Eukaryotic microbes (protists) that occupy low-oxygen environments often have drastically different mitochondrial metabolism compared to their aerobic relatives. A common theme among many of anaerobic protists is the serial loss of components of the electron transport chain (ETC). Here, we discuss the diversity of the ETC across the tree of eukaryotes and review hypotheses for how ETCs are modifie
One phenomenon causing issues for language learners in the form of cross-linguistic influence (CLI) is translation ambiguity (Eddington & Tokowicz, 2013). Translation ambiguity refers to a situation where word meanings are different in a speaker’s languages. To give an example, Swedish does not lexicalize any difference between TO LEND and TO BORROW, whereas this distinction is made in English
The transport of neutrons in long beamlines at spallation neutron sources presents a unique challenge for Monte-Carlo transport calculations. This is due to the need to accurately model the deep-penetration of high-energy neutrons through meters of thick dense shields close to the source and at the same time to model the transport of low- energy neutrons across distances up to around 150 m in leng
Unfair work distribution is common in project-based learning with teams of students. One contributing factor is that students are differently skilled developers. To mitigate the differences in a course with group work, we introduced mandatory programming lab sessions. The intervention did not affect the work distribution, showing that more is needed to balance the workload. Contrary to our goal, t
As Netscape co-founder Marc Andreessen famously remarked in 2011, software is eating the world - becoming a pervasive invisible critical infrastructure. Data on the distribution of software use and development in society is scarce, but we compile results from two novel surveys to provide a fuller picture of the role software plays in the public and private sectors in Sweden, respectively. Three ou
The quark gluon plasma produced in ultrarelativistic heavy-ion collisions at the Large Hadron Collider (LHC) can be studied by measuring the modifications of jets formed by hard scattered partons which interact with the medium. We studied these modifications via angular correlations of jets with charged hadrons for jets with momenta 20
Background: A previous study has indicated poorer narrative ability during retelling in 5-year-olds with unilateral cleft lip and palate (UCLP) as a group, compared to peers without UCLP. Aim: To investigate if there are any differences between 5-year-olds with and without UCLP in narrative ability during retelling. Methods: A total of 83 children participated, 51 with UCLP and 32 without. They ha
