Witt kernels of quadratic forms for multiquadratic extensions in characteristic 2 [PDF]

open access: yes, 2014
Let $F$ be a field of characteristic $2$ and let $K/F$ be a purely inseparable extension of exponent $1$. We show that the extension is excellent for quadratic forms. Using the excellence we recover and extend results by Aravire and Laghribi who computed

Lag synchronization and scaling of chaotic attractor in coupled system [PDF]

open access: yes, 2012
We report a design of delay coupling for lag synchronization in two unidirectionally coupled chaotic oscillators. A delay term is introduced in the definition of the coupling to target any desired lag between the driver and the response. The stability of

Quasi-Steady State Time Model of Fire Smoke Transmission in Long-Narrow Spaces

open access: yesShanghai Jiaotong Daxue xuebao, 2022
Transport time lag is a crucial characteristic of fire spreading in fire early stage, which determines the activation time of the fire detector. To clarify the quantitative relationship between the delay behavior and the quasi-steady state of smoke ...

Transition from anticipatory to lag synchronization via complete synchronization in time-delay systems [PDF]

open access: yes, 2005
The existence of anticipatory, complete and lag synchronization in a single system having two different time-delays, that is feedback delay $\tau_1$ and coupling delay $\tau_2$, is identified.

Evaluation of classification and decision trees in predicting daily precipitation occurrences

open access: yesWater Supply, 2022
Due to the heterogeneous distribution of precipitation, predicting its occurrence is one of the primary and basic strategies to prevent possible disasters and their damages.

”Lagen”: ett användbart fokus för religionsinkluderande exphil?

open access: yesNorsk Filosofisk Tidsskrift, 2022
Artikeln är ett personligt, religionsvetenskapligt inlägg i debatten om exphil-ämnets innehåll. Två argument utvecklas. För det första att exphil bör inkludera religionsvetenskap och universitetsteologi, eftersom dessa två humanistiska ämnen är delaktiga

The changing X-ray time lag in MCG-6-30-15 [PDF]

open access: yes, 2014
MCG-6-30-15 is one of the most observed Narrow Line Seyfert 1 galaxies in the X-ray band. In this paper we examine the X-ray time lags in this source using a total of 600 ks in observations (440 ks exposure) taken with the XMM-Newton telescope (300 ks in

Normal sleep bouts are not essential for C. elegans survival and FoxO is important for compensatory changes in sleep [PDF]

open access: yes, 2018
Additional file 6: Decreased lag-2 function does not slow vulval development. The progeny of wild type and lag-2(q420) animals raised at 25.5 °C were selected at the L4 stage, prior to lethargus entry. Vulval eversion was scored after 3 h; the percentage

The effects of hemodynamic lag on functional connectivity and behavior after stroke [PDF]

open access: yes, 2015
Stroke disrupts the brain's vascular supply, not only within but also outside areas of infarction. We investigated temporal delays (lag) in resting state functional magnetic resonance imaging signals in 130 stroke patients scanned two weeks, three months
