Surviving severe traumatic brain injury in Denmark: incidence and predictors of highly specialized rehabilitation
No full textLene Odgaard,1 Ingrid Poulsen,2 Lars Peter Kammersgaard,2 Søren Paaske Johnsen,3 Jørgen Feldbæk Nielsen,1 1Hammel Neurorehabilitation Center and University Research Clinic, Aarhus University, Aarhus, Denmark; 2Department of Neurorehabilitation, TBI and Research Unit on Brain injury rehabilitation (RUBRIC), Glostrup Hospital, Copenhagen University, Copenhagen, Denmark; 3Department of Clinical Epidemiology, Aarhus University Hospital, Aarhus, Denmark Purpose: To identify all hospitalized patients surviving severe traumatic brain injury (TBI) in Denmark and to compare these patients to TBI patients admitted to highly specialized rehabilitation (HS-rehabilitation). Patients and methods: Patients surviving severe TBI were identified from The Danish National Patient Registry and The Danish Head Trauma Database. Overall incidence rates of surviving severe TBI and incidence rates of admission to HS-rehabilitation after severe TBI were estimated and compared. Patient-related predictors of no admission to HS-rehabilitation among patients surviving severe TBI were identified using multivariable logistic regression. Results: The average incidence rate of surviving severe TBI was 2.3 per 100,000 person years. Incidence rates of HS-rehabilitation were generally stable around 2.0 per 100,000 person years. Overall, 84% of all patients surviving severe TBI were admitted to HS-rehabilitation. Female sex, older age, and non-working status pre-injury were independent predictors of no HS-rehabilitation among patients surviving severe TBI. Conclusion: The incidence rate of hospitalized patients surviving severe TBI was stable in Denmark and the majority of the patients were admitted to HS-rehabilitation. However, potential inequity in access to HS-rehabilitation may still be present despite a health care system based on equal access for all citizens.

LP Decoding Excess over Symmetric Channels
No full textWe consider the problem of Linear Programming (LP) decoding of binary linear codes. The LP excess lemma was introduced by the first author, B. Ghazi, and R. Urbanke (IEEE Trans. Inf. Th., 2014) as a technique to trade crossover probability for 'LP excess' over the Binary Symmetric Channel. We generalize the LP excess lemma to discrete, binary-input, Memoryless, Symmetric and LLR-Bounded (MSB) channels. As an application, we extend a result by the first author and H. Audah (IEEE Trans. Inf. Th., 2015) on the impact of redundant checks on LP decoding to discrete MSB channels. © 2015 IEEE
A Sobolev estimate for radial lp-multipliers on a class of semi-simple lie groups
No full textLet G be a semi-simple Lie group in the Harish-Chandra class with maximal compact subgroup K. Let ΩK be minus the radial Casimir operator. Let 1 4 dim(G/K) < SG < 1 2 dim(G/K), s ∈ (0, SG] and p ∈ (1,∞) be such that(1 p - 1 2 )< s 2SG . Then, there exists a constant CG,s,p > 0 such that for every m ∈ L∞(G) ∩ L2(G) bi-K-invariant with m ∈ Dom(Ωs K) and Ωs K(m) ∈ L2SG/s(G) we have, (0.1) ∥Tm : Lp(G) → Lp( G)∥ ≤ CG,s,p∥Ωs K(m)∥ L2SG/s(G), where Tm is the Fourier multiplier with symbol m acting on the noncommutative Lp-space of the group von Neumann algebra of G. This gives new examples of Lp-Fourier multipliers with decay rates becoming slower when p approximates 2.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Analysi
Stability properties of stochastic maximal Lp-regularity
No full textIn this paper we consider Lp-regularity estimates for solutions to stochastic evolution equations, which is called stochastic maximal Lp-regularity. Our aim is to find a theory which is analogously to Dore’s theory for deterministic evolution equations. He has shown that maximal Lp-regularity is independent of the length of the time interval, implies analyticity and exponential stability of the semigroup, is stable under perturbation and many more properties. We show that the stochastic versions of these results hold
PROPAGATION OF LP//0//1 AND LP//1//1 MODES IN COUPLED OPTICAL FIBERS.
No full textThe author studied the propagation of the fundamental mode, called the LP//0//1 mode, of a single-mode optical fiber and the LP//1//1 mode, the next higher-order mode, in two long lengths of fiber coupled together. This was done by launching light having a wavelength below the cut-off wavelength of the fiber. The effect of lateral misalignment at the coupled junctions was investigated. The results are explained in terms of excitation of the modes at this junction
Life of a Yellow Kid: an audiovisual electro-pop LP
No full textThe basis of this project is to compose, record, produce and mix an eleven song album (LP) with a visualizer, logo and design for each track. The author designed all of the artworks for the songs and LP and produced videos and content for said LP. Also, the author combined all of his influences from electronic music and other genres to create something new to expand the limits of electronic music. This album was influenced by works of artists like Madeon, Porter Robinson, Louis The Child, Urboi, Medasin, Fred Again.. and The Weeknd. Song-writing, recording, sound design, creative production techniques, mixing, graphic design and audiovisual production were the skills and tools necessary for the completion of this LP. The main focus of the LP was to combine different genres of music, like Electro-pop, UK Garage, Pop, House and Drum and Bass. Also this album is about personal experiences of the author and it covers different feelings throughout the LP, creating a sunset literally and figuratively within the album.

Positive Definite Functions for the Class Lp(G
No full textTitle: Positive Definite Functions for the Class Lp(G), Author: Shaunkat A. Warsi, Location: ThodeThis thesis contains four main theorems on Positive definite functions for the class Lp(G) over compact and locally compact groups. Information as to how the class P(F) varies with F is provided by those theorems. Some topological properties of the set P(Lp) ∩ Lq have been considered. Two results analogous to those of E. Hewitt and H. A. Naimark have also been proved.ThesisMaster of Science (MS
Resolvent Estimates in (weighted) Lp spaces for the Stokes Operator in Lipschitz Domains
No full textRecently, by Z. Shen, resolvent estimates for the Stokes operator were established in Lp(Ω) when Ω is a Lipschitz domain in Rd, with d≥3 and |1/p-1/2|<1/(2d)+ε. This result implies that the Stokes operator generates a bounded analytic semigroup in Lp(Ω) in the case that Ω is a three-dimensional Lipschitz domain and 3/2-ε<p<3+ε. To fully understand the work of Z. Shen, a lot of background information is needed. In this thesis the resolvent estimates are studied in detail in the case d=3. In the end the results of Shen are extended to resolvent estimates in Lp(w,Ω), where Ω is a three-dimensional Lipschitz domain, |1/p-1/2|<1/6, and w∈A2p/3∩RH3/(3-p) is a weight function that belongs to an intersection of a Muckenhoupt weight class and satisfies a reverse Hölder inequality
