We use femtosecond transient absorption spectroscopy to study chlorophyll (Chl)-Chl energy transfer in the peridinin-chlorophyll protein (PCP) reconstituted with mixtures of either chlorophyll b (Chlb) and Chld or Chla and bacteriochlorophyll a (BChla). Analysis of absorption and transient absorption spectra demonstrated that reconstitution with chlorophyll mixtures produces a significant fraction
OBJECTIVE-To report the incidence of sight-threatening vascular lesions in type 2 diabetic subjects without retinopathy after adopting a 3-year interval screening program. RESEARCH DESIGN AND METHODS-In all, 1,691 type 2 diabetic subjects with no detectable retinopathy in two 50 degrees red-free fundus photographs were scheduled for follow-up with photography 3 years later. Age at diabetes diagnos
This paper presents a wideband CMOS power amplifier intended for cellular handset applications. The circuit exploits injection locking to achieve a power gain of 20.5dB from a single stage amplifier. The maximum output power of 29dBm, with a peak drain- and power-added-efficiency (PAE) of 66% and 64%, respectively, occurs at a center frequency of 2GHz with a 3V supply. A cross-coupled cascode topo
Three young men were trapped in a car at the bottom of a canal at two meters depth, after losing control of their vehicle. They were brought up by rescue divers and found in cardiac arrest. One of three patients had return of spontaneous circulation (ROSC), at 47 min after the accident. This sole survivor had the longest submersion time of the three and he received continued mechanical chest compr
Delivery of fetuses with intrauterine growth restriction (IUGR) with abnormal umbilical artery blood flow in the second trimester represents a clinical dilemma. So far, no evidence based management protocols are available adressing when to deliver these fetuses. The high risk of hypoxia and fetal death has to be balanced against that of extreme preterm birth with associated morbidity. The clinical
The particle formation and growth events observed at a semirural background site in Denmark were analyzed based on particle number size distribution data collected during the period from February 2005 to December 2010. The new particle formation (NPF) events have been classified visually in detail according to 3D daily plots in combination with an automatic routine. A clear seasonal variation was
The immediate environment of handset antennas, including the casings and the users holding the handsets, has a strong impact on the radio channel in mobile communication. In this paper we investigate a composite channel method that synthetically combines double-directional measurements of the userless propagation channel with measured super-antenna patterns, i.e., patterns of the combined antenna-
Microscopic colitis (MC) often debuts around or after menopause and is divided into lymphocytic- and collagenous colitis. The aim of this study was to examine whether factors influencing sex hormone levels differed between subgroups of MC as well as between patients and controls. A self-administered questionnaire about parity was completed which included questions surrounding age at first childbir
Ostreopsis ovata is a benthic dinoflagellate that produces palytoxin and its analogues. Since the end of the 1990s, toxic blooms of O. ovata have been recorded in many tropical and temperate marine waters. These blooms often kill benthic invertebrates and cause health problems for humans. We hypothesize that increases in seawater temperature might induce these blooms. A strain of O. ovata isolated
Analyses assessed the degrees to which personality accounts for associations between marital quality and parenting and mediates genetic contributions to these relationships. Participants included 318 male and 544 female same-sex twin pairs from the Twin and Offspring Study in Sweden. All twins completed self-report measures of marital quality and personality (anxiousness, aggression, sociability).
The crustal segment Volgo-Uralia is the least known part of the East European Craton. Its crystalline crust is hidden beneath a thick Neoproterozoic to Phanerozoic cover but disclosed by thousands of drill holes. In conjunction with the recent "Tatseis" reflection seismic profile, we conducted the first isotopic study of the Bakaly granitoid block in eastern Volgo-Uralia, which represents a subsur
Spatial multiplexing using Massive MIMO has been shown to have very promising properties, including large gains in spectral efficiency and several orders of magnitude lower transmit power, as compared to today's access schemes. The properties of massive MIMO have been studied mostly for theoretical channels with independent and identically distributed (i.i.d.) complex Gaussian coefficients. To eff
Prefetching is a well known concept for CPUs but for GPUs it is fairly unexplored. The memory management of a GPU plays a crucial role in its performance, and cache prefetching has the potential to lower the overall latency. This thesis compares different types of prefetching methods for GPUs and remaking some CPU prefetchers to fit the GPU architecture. All these prefetchers were then put inside
Hanöbukten och dess invånare Vattenkvaliteten i Hanöbukten har försämrats de senaste åren. Detta är ett aktuellt ämne som berör alla buktens invånare, land- som vattenlevande. Regeringen har nyligen insett allvaret i situationen och har delegera till Havs- och vattenmyndigheten att göra en större utredning för att gå till botten med problemet. Fågeldöd, sjuk och mager fiskar samt minskade fångste
This research explores the interplay between strategic communication and legitimacy in United Nations (UN) peacekeeping missions, focusing on the United Nations Stabilization Mission in the Democratic Republic of Congo (MONUSCO) and addresses the challenge of maintaining and establishing legitimacy through strategic communication during crises. The study specifically investigates the use of strate
Cancer är en otrevlig sjukdom, som drabbar många människor. Man söker ständigt nya och bättre sätt att bota patienter eller åtminstone lindra sjukdomens framfart. Ett vanligt sätt att behandla cancer är med strålning. Strålningen kan bestå av sk fotoner. Fotoner är samma slags partiklar som t.ex. vanligt ljus. Skillnaden är att de fotoner som används vid strålbehandling av cancer har högre energi "Purpose: The aim of this study was to investigate whether inversely planned intensity modulated radiation therapy (IMRT), using the clinical radiotherapy equipment at hand in our department, renders any advantages regarding dose distribution over conventional radiotherapy for head and neck cancer patients in the ARTSCAN (Accelerated RadioTherapy of Squamous cell Carcinoma in the head And Nec
