- For digital circuits with ultra-low power consumption,floating-gate circuits have been considered to be a techniquepotentially better than standard static CMOS circuits.By having a DC offset on the floating gates, theeffective threshold voltage of the floating-gate transistoris adjusted and the speed and power performance can bealtered. In this paper the basic performance related propertiessuch as power, delay, power-delay product (PDP),and energy-delay product (EDP) for floating-gate circuitsoperating in subthreshold are investigated. Based on circuitsimulations in a 120nm process technology, it isshown that for the best case, the power can be reducedapproximately by one order of magnitude at the expenseof increased delay, while the PDP is more or less constantin comparison to static CMOS. The EDP can be reducedby two orders of magnitude at the expense of reducednoise margins.

- Denna presentation handlar om poesins möjlighet att erbjuda en annan väg framåt, i relation till den kristid vi lever i, som yttras sig i relation till klimat, till kommunikation, politik m.m. Poesins fokus på diversitet och samtidighet ger denna möljlighet, vilket i föredraget visas genom analyser av Cia Rinnes transmediala och flerspråkiga verk "Notes for Soloists/Sounds for Soloists" och Athena Farrokhzads "Sommar i P1" från 2014, betraktat som en poetisk performance.

Ida Börjel and the Politics of Form
- 2011

Ingår i: "Norlit 2011. Conference on Literature and Politics", 2011-08-05, Roskilde, Denmark.

Konferensbidrag (refereegranskat)abstract
- The paper studies the political implications of linguistic and literary conventions, through theorists like Jean-Jacques Lecercle, Jacques Rancière, and Marjorie Perloff. My touchstone will be the poetry of Swedish contemporary poet Ida Börjel. What is focused in Börjel’s writing is her tendencies to use “found objects”, and to question the representational function of language, as its primary function. These tendencies correspond well to e.g. Rancière’s thoughts on literature and its relation to life, as well as to Lecercle’s discussions on the barriers between what is inside language’s conventions, and what is left outside (“the remainder”). The paper dwells on certain political dimensions of theories like theirs, from a perspective which might, at least to a certain extent, be described as culture-semiotic: What ideologies come with a certain semiotic understanding, with certain linguistic conventions? And what ideologies surface when these conventions, this understanding, is questioned in one way or the other? Concepts like parataxis and language materialism will be crucial to my discussion, since these concepts (or at least certain facets of them) stress functions of language and literature which are not representational. Lecercle’s theories on “the remainder” of language prove very effective when applied not specifically as linguistic tools primarily, but as tools for literary analysis. Especially when one approaches a literature which tries to scrutinize, and even transgress, its own boundaries and conventions – as does Börjel’s. This concept also proves a useful complement in relation to Rancière’s more qualitative concept of the “political”, and its relationship to literature specifically. Rancière speaks mainly of the novel, and Lecercle mainly of language (in more general terms). Within the habitat of Marjorie Perloff’s theories of experimental poetry, these two theoretical perspectives can find an environment where literary form and politics have a lot to say to each other. And the outcome of such a discussion would have relevance when it comes to the relationship between such politically radiant pairs as nature and culture, or ecology and economy.

Similar outcome with an invasive strategy in men and women with Non ST-Elevation Acute Coronary Syndromes
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Gender differences in benefit from an early invasive strategy in patients with Non ST-elevation Acute Coronary Syndromes (NSTE ACS) have been debated and results are conflicting. Some studies have even indicated harm for women associated with a routine invasive strategy. Method: We included 46 455 patients ( 14 819 women (32%) and 31 636 men (68%)) from The Register of Information and Knowledge about Swedish Heart Intensive care Admissions (RIKS-HIA), with a diagnosis of either unstable angina pectoris or non-ST-elevation myocardial infarction. All patients were admitted to intensive coronary care units in Sweden, between 2000 and 2006, and followed for 1 year. Adjustment for baseline differences between the genders was made. Results: In the non-invasive strategy arm relative risk (RR) of death was (women vs. men) 1.02 (95% CI, 0.94-1.11) and in the invasive strategy arm 1.12 (95% CI, 0.96-1.29). After adjustment for baseline differences between the genders with propensity score and discharge medication there was a trend towards lower mortality among women, RR 0.90 (95% CI, 0.82-0.99) in the early non-invasive group but still no difference in the early invasive cohort RR 0.90 (95% CI, 0.76-1.06). Results were similar with the combined end-point death/MI. The risk reduction with an invasive strategy was similar in women (RR 0.46 (95% CI 0.38-0.55)) and men (RR 0.45 (95% CI 0.40-0.52). Conclusion: In this large cohort of patients with NSTE ACS, reflecting real life management, women and men had similar outcome and similar benefit with an early invasive strategy.
