Underwater source localization in the presence of strong interference

The underwater localization of a broadband target in the presence of strong interference and noise has been widely investigated. A novel clutter suppression approach based on oblique projections is proposed, exploiting the prior information of the expected target response. The method uses a generalised likelihood ratio formulation to select the oblique projection best matching the measured data. T

Do Firm Support Increase Investments? Evidence from the Aquaculture and Fish Processing Sectors in Sweden

The European Union provides firm support to the maritime sector to reach the policy objectives in the Common Fisheries Policy. This paper analyzes to what extent the investment support to aquaculture and fish processing firms in Sweden increases firm investment activity. By doing so, the paper also quantifies the amount of investments that would have been undertaken also without support (deadweigh

A di‑iron(III) μ-oxido complex as catalyst precursor in the oxidation of alkanes and alkenes

The oxido-bridged diiron(III) complex [Fe2(μ-O)(μ-OAc)(DPEAMP)2](OCH3) (1), based on a new unsymmetrical ligand with an N4O donor set, viz. [2-((bis(pyridin-2-ylmethyl)amino)methyl)-6-((ethylamino)methyl)-4-methylphenol (HDPEAMP)], has been prepared and characterized by spectroscopic methods and X-ray crystallography. The crystal structure of the complex reveals that each Fe(III) ion is coordinate

Pulsed laser deposited transparent and conductive V-doped ZnO thin films

ZnO and vanadium-doped ZnO (0.7–4.1 at.%) thin films were deposited onto corning glass substrates by the pulsed laser deposition technique using a KrF excimer laser (λ = 248 nm). The films were deposited at 500 °C under an oxygen pressure of 1 Pa with a laser fluence of 2 J/cm2. The structural, morphological, optical and electrical properties as a function of the dopant atomic concentration were i

A Schumpeter Hotel? Surname Status Persistence in Sweden 1880-2016

Conventional social mobility research misses substantial inequalities of opportunity. To capture intergenerational persistence of family social status we need to move beyond parent-child associations in occupation or income. Models that incorporate surname group belonging show that families do not regress to a population mean at the speed implied by parent-child associations. Their mobility is fur

Arctic amplification modulated by Atlantic Multidecadal Oscillation and greenhouse forcing on multidecadal to century scales

Enhanced warming in the Arctic (Arctic amplification, AA) in the last decades has been linked to several factors including sea ice and the Atlantic Multidecadal Oscillation (AMO). However, how these factors contributed to AA variations in a long-term perspective remains unclear. By reconstructing a millennial AA index combining climate model simulations with recently available proxy data, this wor

Accurate prediction of B-form/A-form DNA conformation propensity from primary sequence : A machine learning and free energy handshake

DNA carries the genetic code of life, with different conformations associated with different biological functions. Predicting the conformation of DNA from its primary sequence, although desirable, is a challenging problem owing to the polymorphic nature of DNA. We have deployed a host of machine learning algorithms, including the popular state-of-the-art LightGBM (a gradient boosting model), for b

Transcriptional profiling demonstrates altered characteristics of CD8 + cytotoxic T-cells and regulatory T-cells in TP53-mutated acute myeloid leukemia

Background: Acute myeloid leukemia (AML) patients have limited effect from T-cell-based therapies, such as PD-1 and CTLA-4 blockade. However, recent data indicate that AML patients with TP53 mutation have higher immune infiltration and other immunomodulatory therapies could thus potentially be effective. Here, we performed the transcriptional analysis of distinct T-cell subpopulations from TP53-mu

Promoting nature-based solutions: Guideline for integrating ecosystem-based adaptation into municipal planning and governance

Det här dokumentet ger lokala politiker och tjänstemän ett processorienterat verktyg för att stärka förankringen (integreringen) av ekosystembaserad klimatanpassning i relevanta sektorer av kommunal verksamhet. Guiden presenterar systematiskt de nivåer och områden där förankring av ekosystembaserad klimatanpassning är viktigt, och möjliggör på så sätt planering och bedömning av åtgärder. Det övergThis guideline offers local government officers and local politicians process‐oriented assistance for integrating ecosystem‐based adaptation within relevant sectors of municipal administration with the aim of fostering sustainable urban development. It is thus an instrument to support leadership of this integration process. The levels and areas where integration of ecosystem‐based adaptation isrel

ADP-ribosylating adjuvant reveals plasticity in cDC1 cells that drive mucosal Th17 cell development and protection against influenza virus infection

Migratory dendritic cells expressing CD103 are the targets for mucosal vaccines. These belong to either of two lineage-restricted subsets, cDC1 or cDC2 cells, which have been linked to priming of functionally distinct CD4 T cells. However, recent studies have identified plasticity in cDC2 cells with overlapping functions with cDC1 cells, while the converse has not been reported. We genetically eng

Galectin-9 Signaling Drives Breast Cancer Invasion through Extracellular Matrix

Aberrations in glycan and lectin expression and function represent one of the earliest hallmarks of cancer. Among galectins, a conserved family of β-galactoside-binding lectins, the role of Galectin-9 in immune-tumor interactions is well-established, although its effect on cancer cell behavior remains unclear. In this study, we assayed for, and observed, an association between Galectin-9 expressio

Animal navigation: A noisy magnetic compass?

Diverse organisms use Earth’s magnetic field as a cue in orientation and navigation. Nevertheless, eliciting magnetic orientation responses reliably, either in laboratory or natural settings, is often difficult. Many species appear to preferentially exploit non-magnetic cues if they are available, suggesting that the magnetic sense often serves as a redundant or ‘backup’ source of information.
