Sinusitis is a common disease caused by a virus or bacteria, with 84% to 91% of cases caused by a viral pathogen. However, physicians prescribe antibiotics for this disease in 85% of all cases. GPX Medical is a company working on the development of a medical device which, by means of absorption spectroscopy, can determine whether the disease is caused by virus or bacteria supporting, thus, the doc
In response to the pressures of predation, parasitism and competition for limited resources, several groups of (mainly) tropical bees and wasps have independently evolved a nocturnal lifestyle. Like their day-active (diurnal) relatives, these insects possess apposition compound eyes, a relatively light-insensitive eye design that is best suited to vision in bright light. Despite this, nocturnal be
Microsoft Word - BTBU Fredrik ht18.docx Travel Report by Fredrik, autumn semester 2018 • Why did you apply to your host university? I have had an interest in China since my first visit in 2008. I had a feeling that I have to go back there one day and now I had the opportunity to do so. Not for traveling but to study and experience more of Beijing. BTBU was the only university in Beijing that I cou

Many insect-pollinated plants use floral scent signals to attract and guide the effective pollinators, and temporal patterns of their floral scent emission may be tuned to respond to the pollinator's activity and pollination status. In the intimate nursery pollination mutualism between monoecious Glochidion trees (Phyllanthaceae) and Epicephala moths (Gracillariidae), floral scent signals mediate

Cyber-Physical Systems (CPS) are integral to critical infrastructure, but their interconnected nature exposes them to sophisticated cyber threats. Traditional security mechanisms primarily focus on detecting direct manipulations of control signals or sensor data, leaving them vulnerable to more subtle attack vectors. This paper introduces a novel optimisation framework for modelling and executing

Syftet med projektet har varit att utveckla Certecklockan till ett bärbart tidshjälpmedel. Certecklockan är ett tidshjälpmedel som mäter tiden i längd, detta för att hjälpa personer med kognitiva funktionshinder att få en bättre tidsuppfattning. I början av projektet hade vi ett antal olika förslag så som armbandsur, något att hänga runt halsen, mobiltelefon mm. Men vi kom till slut fram till att The aim of this project was to develop the Certec Clock into a portable time aid. The Certec Clock measures time in length to help people with cognitive limitations gain a better perception of the concept of time. At the beginning of the project, we came up with a variety of ideas including a wristwatch, a necklace watch and a mobile phone. We reached the conclusion that a handheld computer was th
It is beneficial for both investors and companies to avoid the detrimental consequences of overpricing during an initial public offering (IPO). Prospectuses are an important source of information for potential investors. Through Latent Dirichlet Allocation (LDA) we extract topics from the summary section of prospectuses S-1 for companies holding an IPO in the U.S. in 2019-2020. We represent the un
Den amerikanska staden Phoenix ligger omgiven av berg i Sun Valley, Arizona. Klimatet är varmt och glest utspridda kaktusar står som eldgafflar mot skyn. Tänk på en typisk Vilda Västern-film så får du en förnimmelse av vad som kännetecknar Phoenix omgivningar. Trots ökenlika förhållanden bor där idag 1,3 miljoner invånare. Befolkningstillväxten tog fart på allvar luftkonditioneringen introducerade

Quantum Cascade Lasers (QCLs) have since their invention in 1994 become a crucial source for mid-infrared and THz radiation. Mid-infrared QCLs have achieved room temperature operation while THz QCLs have not. As such, simulations are an important tool in order to achieve a THz QCL operational at room temperature. This work uses a simulation package based on a nonequilibrium Green’s function model
Objective: The present study addresses the problem of estimating the respiratory rate from the mor- phological ECG variations in the presence of atrial fibrilla- tory waves (f-waves). The significance of performing f-wave suppression before respiratory rate estimation is investi- gated. Methods: The performance of a novel approach to ECG-derived respiration, named “slope range” (SR) and de- signed
Popular Abstract in Swedish Personer som arbetar med joniserande strålning inom t.ex. sjukvård, kärnteknik och forskning använder så kallade dosimetrar för att registrera hur mycket joniserande strålning (vilken stråldos) personen blivit utsatt för under ett arbetspass eller en arbetsmånad. Den stråldos som en dosimeter mäter ger ett mått på risken för eventuella sena hälsoeffekter i form av en ökIn the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. To make accurate assessments of the radiological consequences of an emergency situation, methods of re
Based on spectra from F and G dwarf stars, we present elementalabundance trends in the Galactic thin and thick disks in the metallicityregime -0.8< [Fe/H < +0.4. Our findings can besummarized as follows. 1) Both the thin and the thick disks show smoothand distinct abundance trends that, at sub-solar metallicities, areclearly separated. 2) For the alpha -elements the thick disk showssignatures of c
In marked contrast with the ideal error-free feedback assumption that is common in the literature, practical systems are likely to have severely bandwidth-limited, error-prone feedback channels. We consider the scenario where feedback from the receiver is used by the transmitter to select the best antenna, out of many available antennas, for data transmission. Feedback errors cause the transmitter
The single-aliquot regenerative-dose (SAR) protocols used in retrospective dosimetry for optically stimulated luminescence measurements have been mainly developed for archaeological and geological dating of quartz and feldspar. The aim in this study is to find a read-out protocol that can generate the most reproducible signal for household salt (NaCl) at absorbed doses below 100 mGy. The relation
Background: The Epidermal Growth Factor Receptor (EGFR) activated Extracellular-signal Regulated Kinase (ERK) pathway is a critical cell signalling pathway that relays the signal for a cell to proliferate from the plasma membrane to the nucleus. Deregulation of the EGFR/ERK pathway due to alterations affecting the expression or function of a number of pathway components has long been associated wi
