This paper presents a 2.45 GHz wake-up receiver front-end intended for use in sensor networks, and is designed to receive data modulated with on-off-keying. Manufactured in 65 nm CMOS it employs an uncertain IF structure with three phase passive mixer and high gain amplifier chain. With the modulation frequency response tailored to the detector behaviour, it achieves a sensitivity of -88 dBm at BE
Chromosomal instability is a known hallmark of many cancers. DNA polymerases represent a group of enzymes that are involved in the mechanism of chromosomal instability as they have a central function in DNA metabolism. We hypothesized that genetic variation in the polymerase genes may affect gene expression or protein configuration and by that cancer risk and clinical outcome. We selected four gen
This study explored frail older adults' overall experience of receiving health care and/or social services. Frail older adults with unstable health are dependent on the health care system because of the frequency of their contacts with it. More knowledge is needed about how they experience the health care and social services they receive. Interviews with 14 older adults (mean age = 81) revealed on
This paper presents the Gothenburg Population Panel (GOPP), a random sample of individuals who were living in Gothenburg at some point in time during the period 1915-1943. The individuals in the GOPP were searched for every fourth year in the registers of local tax authorities. The hit rate was high; 95 percent of the individuals and 87 percent of the possible observations in the initial master sa
We have used X-ray photoelectron spectroscopy to study the adsorption of L-cysteine on a rutile TiO2(110) surface at room temperature and -65 degrees C. For the molecules in direct contact with the surface our results suggest that the molecules bind dissociatively to the fivefold-coordinated Ti atoms of the surface through their deprotonated carboxylic groups. A second, dissociative interaction oc
Molecular classification of breast cancer (BC) identified diverse subgroups that encompass distinct biological behavior and clinical implications, in particular in relation to prognosis, spread, and incidence of recurrence. Basal-like breast cancers (BLBC) compose up to 15% of BC and are characterized by lack of estrogen receptor (ER), progesterone receptor (PR), and HER-2 amplification with expre
The Mar del Plata International Water Conference provided the first global assessment of the water sector. It was found that in most developing countries the state of water supply and sanitation services were deplorable. Consequently, a call for concerted action to improve coverage and efficiency of the water supply and sanitation sector was launched. This call resulted in the International Water
Objectives To investigate the capacity of Cerament (R), an injectable bone substitute, to guide bone generation from a cortical surface. Materials and method Cerament (R) was applied to the cortical surface of rat tibiae and investigated histologically after 3, 6 and 12 weeks, using a procedure similar to that performed in sham-operated rats. Results In both groups, the thickness of the bone corte
Recently, we constructed a focused antibody library tailored to interact with haptens. High functionality of this library was demonstrated, as specific binders could be retrieved to a range of different haptens. In the current study we have developed a mutagenesis and selection strategy in order to further fine-tune the hapten binding properties of these antibody fragments. Testosterone was chosen
This paper is a translation of my "Preference Utilitarianism by Way of Preference Change?", in which I revisit Richard Hare’s classical and much discussed argument for preference utilitarianism (Moral Thinking, 1981), which relies on the conception of moral deliberation as a process of thought experimentation, with concomitant preference change. The paper focuses on an apparent gap in Hare’s reaso
The subject of the thesis is the psychê, a Greek word whose closest equivalent is the Swedish “själ”, the English “soul”, the French “âme” and the German “Seele”. The meanings of these words are far from being the same. What is more, the Greek psychê has shifting meanings, both synchronically and diachronically speaking. We are faced with two problems: What does the word psychê designate and how i
Background: Hitherto, risk prediction models for preoperative ultrasound-based diagnosis of ovarian tumors were dichotomous (benign versus malignant). We develop and validate polytomous models (models that predict more than two events) to diagnose ovarian tumors as benign, borderline, primary invasive or metastatic invasive. The main focus is on how different types of models perform and compare. M
Obesity and associated metabolic disorders have been implicated in liver carcinogenesis; however, there are little data on the role of obesity-related biomarkers on liver cancer risk. We studied prospectively the association of inflammatory and metabolic biomarkers with risks of hepatocellular carcinoma (HCC), intrahepatic bile duct (IBD), and gallbladder and biliary tract cancers outside of the l
