Fisk- och skaldjursbestånd i hav och sötvatten 2017 : Resursöversikt
- 2017
-
Reports (other academic/artistic)abstract
- I rapporten kan du ta del av bedömningen som görs av situationen för bestånd som regleras inom ramen för EU:s gemensamma fiskeripolitik (GFP). Bedömningarna baseras på det forskningssamarbete och den rådgivning som sker inom det Internationella Havsforskningsrådet (ICES).De bestånd som förvaltas nationellt baseras på de biologiska underlagen, och rådgivningen i huvudsak på den forskning och övervakning samt analys som bedrivs av Institutionen för akvatiska resurser vid Sveriges lantbruksuniversitet (SLU Aqua) samt yrkesfiskets rapportering.Rapporten omfattar 41 fiskarter och sju skaldjursarter.Nytt för i år är att vi även beskriver fritidsfisket mer utförligt. Det fisket får allt större betydelse för utvecklingen av många av Sveriges bestånd av fisk- och skaldjur, till exempel sötvattens- och kustlevande arter som abborre, gädda, gös, lax, röding och öring, liksom marina arter som torsk och hummerÖversikten är utarbetad av SLU Aqua på uppdrag av Havs- och vattenmyndigheten.

Systemic Inflammation in Preclinical Ulcerative Colitis
- 2021

Journal article (peer-reviewed)abstract
- Background & Aims: Preclinical ulcerative colitis is poorly defined. We aimed to characterize the preclinical systemic inflammation in ulcerative colitis, using a comprehensive set of proteins.Methods: We obtained plasma samples biobanked from individuals who developed ulcerative colitis later in life (n = 72) and matched healthy controls (n = 140) within a population-based screening cohort. We measured 92 proteins related to inflammation using a proximity extension assay. The biologic relevance of these findings was validated in an inception cohort of patients with ulcerative colitis (n = 101) and healthy controls (n = 50). To examine the influence of genetic and environmental factors on these markers, a cohort of healthy twin siblings of patients with ulcerative colitis (n = 41) and matched healthy controls (n = 37) were explored.Results: Six proteins (MMP10, CXCL9, CCL11, SLAMF1, CXCL11 and MCP-1) were up-regulated (P < .05) in preclinical ulcerative colitis compared with controls based on both univariate and multivariable models. Ingenuity Pathway Analyses identified several potential key regulators, including interleukin-1β, tumor necrosis factor, interferon-gamma, oncostatin M, nuclear factor-κB, interleukin-6, and interleukin-4. For validation, we built a multivariable model to predict disease in the inception cohort. The model discriminated treatment-naïve patients with ulcerative colitis from controls with leave-one-out cross-validation (area under the curve = 0.92). Consistently, MMP10, CXCL9, CXCL11, and MCP-1, but not CCL11 and SLAMF1, were significantly up-regulated among the healthy twin siblings, even though their relative abundances seemed higher in incident ulcerative colitis.Conclusions: A set of inflammatory proteins are up-regulated several years before a diagnosis of ulcerative colitis. These proteins were highly predictive of an ulcerative colitis diagnosis, and some seemed to be up-regulated already at exposure to genetic and environmental risk factors.

Monte Carlo simulation of vertical MESFETs in 2H, 4H and 6H-SiC
- 2001

In: Diamond and related materials. - 0925-9635 .- 1879-0062. ; 10:3-7, s. 1283-1286

Journal article (peer-reviewed)abstract
- The 4H-SiC static induction transistor (SIT) is a very competitive device for high frequency and high power applications (3-6 GHz range). The large breakdown voltage and the high thermal conductivity of 4H-SiC allow transistors with extremely high current density at high voltages. The SIT transistor shows better output power capabilities but the unity current-gain frequency is lower compared to a MESFET device. In this work we show, using a very accurate numerical model, that a compromise between the features given by the SIT structure and the ordinary MESFET structure can be obtained using the vertical MESFET structure. The device dimension has been selected very aggressively to demonstrate the performance of an optimized technology. We also present results from drift-diffusion simulations of devices, using transport parameters obtained from the Monte Carlo simulation. The simulations indicate that 2H-SiC is superior to both 4H and 6H-SiC for vertical devices. For lateral devices, 2H-SiC is slightly faster compared to an identical 4H-SiC device

The Effect of Different Transport Models in Simulation of High Frequency 4H-SiC and 6H-SiC Vertical MESFETs
- 2001
-
In: Solid-State Electronics. - 0038-1101 .- 1879-2405. ; 45:5, s. 645-653
-
Journal article (peer-reviewed)abstract
- A full band Monte Carlo (MC) study of the high frequency performance of a 4H-SiC Short channel vertical MESFET is presented. The MC model used is based on data from a full potential band structure calculation using the local density approximation to the density functional theory. The MC results have been compared with simulations using state of the art drift-diffusion and hydrodynamic transport models. Transport parameters such as mobility, saturation velocity and energy relaxation time are extracted from MC simulations

Sustainability Jam Sessions for vision creation and problem solving
- 2015
-
In: Journal of Cleaner Production. - : Elsevier. - 0959-6526 .- 1879-1786. ; 98, s. 29-35
-
Journal article (peer-reviewed)abstract
- This article presents a concept for creating arenas where expertise from certain branches of industry can interact with sustainability professionals and researchers to address and solve sustainability challenges. The concept Sustainability Jam Session (SJS) builds upon the idea of conducting creative meetings between professionals in “jam sessions,” similar to those associated primarily with music and improvisation. Approaches such as these have been used in the IT sector over the past decades, but this is the first attempt to apply it in the area of sustainability. SJS's were tested at the 2012 Greening of Industry Network Conference (GIN2012) and here we report our experiences from arranging six SJS's at the conference.A typical process of an SJS includes a preparatory phase, the actual jam, and documentation and follow up. The preparatory phase mainly involves identifying hosts and topics to be addressed at the SJS, followed by attracting participants. The jam is started by an introduction of the topics, a technical visit (if appropriate), and a problem-solving workshop, ending with a wrap-up reporting. Thorough documentation is necessary for following up the results of the SJS and preparing for implementation of the identified solutions.We conclude that skill, structure, setting, and surrender of control, as well as finding “red and hot” topics for the jams are the key factors for successful SJS's.Based on our experiences from GIN2012, we recommend other research conferences in the sustainability field use SJS's if the intention is to boost the interaction between the conference and the host region or non-academic organizations in general. We also suggest that a similar approach can be used in regional development for creating an infrastructure for learning and transformation towards sustainability and initiatives for open innovation.

Conference paper (other academic/artistic)abstract
- A commercial FDTD simulation software is the basis of an ongoing parallelization project. In the first phase of the project the work is aiming at optimization of the program on shared memory computers. In this paper we present the initial methods of parallelization with the achieved performance on a Sun Fire 15K NUMA computer. The achieved results are discussed, together with the possible paths to improve the speedup.

Parallel FDTD calculation efficiency on computers with shared memory architecture
- 2007

Conference paper (peer-reviewed)abstract
- Fast parallel processing of the FDTD method is becoming very important, and its efficiency on different multiprocessor computer architectures should be carefully examined. Is it possible to have the same versatile parallel FDTD simulator working efficiently on a set of very different computer architectures? In contrast to distributed memory systems, shared memory systems can be built with a variety of memory configuration types (and subtypes) as well as combined with distributed memory systems. The paper focuses on viability of different shared memory architectures for parallel FDTD processing. Our analysis concerns the processing method suitable for both shared and distributed memory systems. The results of experiments comparing parallel processing efficiency on different shared memory machines are presented.
