A microstrip antenna integration with a power amplifier is presented for the 60 GHz band. The antenna is a single layer 4×4 square patches array. The power amplifier is injection locked, designed in a 65 nm CMOS technology, with single-ended input and output signals. The integration is realized by means of bond wire connections. The antenna and the power amplifier are fabricated, characterized and

Autoimmune diseases (ADs) are associated with a number of B-cell neoplasms but the associations are selective in regard to the type of neoplasm and the conferred risks are variable. So far no mechanistic bases for these differential associations have been demonstrated. We speculate that developmental origin of B-cells might propose a mechanistic rationale for their carcinogenic response to autoimm

Idag tillhör persondatorerna våra käraste prylar, men så har det inte alltid varit. Kring 1980, då persondatorerna slog igenom i Sverige, sågs "datafrågorna" istället tillhöra samhällets stora utmaningar, tillsammans med bland annat energiförsörjningen och miljöfrågorna. Dessa datafrågor debatterades häftigt, och i fackpressen kritiserades särskilt Sveriges Television för att ge en alldeles för dy

Universal Serial Bus (USB) is a new interface standard for connecting peripheral devices to personal computers. A USB system consists of a host (typically a PC) and a number of peripherals with USB interfaces.In this thesis, we have investigated an alternative approach to the PC based system. We have developed a camera server which connects a USB camera directly to Ethernet. The server is an indep

We introduce a scalable observer architecture to estimate the states of a discrete-time linear-time-invariant (LTI) system whose sensors can be manipulated by an attacker. Given the maximum number of attacked sensors, we build on previous results on necessary and sufficient conditions for state estimation, and propose a novel multi-modal Luenberger (MML) observer based on efficient Satisfiability

Access to palliative care is unequally distributed across Sweden and thus does not meet the needs. The holistic perspective of palliative care is sometimes contrasted with the usual medical focus on organ failure and disease. Palliative consultation teams provide specialist palliative care competencies for staff caring for patients in primary care, nursing homes and in hospitals. Efforts to increa

Objective/Background The objective was to investigate renal outcomes following endovascular repair of thoraco-abdominal aortic aneurysms (TAAA) comparing fenestrations with branches for the renal arteries. Methods Renal outcomes following TAAA endovascular repair performed with renal branches were collected from five high volume European centers and compared with renal outcomes following TAAA endo

Introduction: Alzheimer's disease pathologies are common in dementia with Lewy bodies, but their clinical relevance is not clear. CSF biomarkers amyloid beta 1-42, total tau, and tau phosphorylated at threonine 181 reflect Alzheimer's disease neuropathology antemortem. In PD, low CSF amyloid beta 1-42 predict long-term cognitive decline, but little is known about these biomarkers as predictors for

Cervicogenic or cervical dizziness is debated as an entity. However, there exists both a physiologic basis and a multitude of clinical data to make such a disease concept at least possible and worth considering. In addition, the interaction of proprioceptive and vestibular mechanisms may amplify dizziness of other origin. Cervical pain and dizziness are both common symptoms and may coincide, and n

Prostate cancer (PCa) has a large familial component, but understanding of its genetic basis is fragmentary. Breast cancers may be associated with PCa, but whether this is true for other tumor types is poorly established. We used a novel approach to study familial associations of any type of cancer with PCa. We assessed the relative risk (RR) for all types of tumors as a function of the number of

Introduction: The development of neutralizing antibodies (inhibitors) against coagulation factor VIII (FVIII) is currently the most serious complication for patients with haemophilia A undergoing FVIII replacement therapy. Several genetic factors have been acknowledged as risk factors for inhibitor development. Aim: To analyze the influence of genetic factors on the nature of the humoral immune re

Background: Active surveillance (AS) is commonly used for men with low-risk prostate cancer (PCa). When life expectancy becomes too short for curative treatment to be beneficial, a change from AS to watchful waiting (WW) follows. Little is known about this change since it is rarely documented in medical records. Objective: To model transition from AS to WW and how this is affected by age and comor
