This work treats the estimation of the chromagram for harmonic audio signals using a block sparse reconstruction framework. Chroma has been used for decades as a key tool in audio analysis, and is typically formed using a Fourier-based framework that maps the fundamental frequency of a musical tone to its corresponding chroma. Such an approach often leads to problems with tone ambiguity, which we

The effect of temperature on the adiabatic laminar burning velocities of CH4 + air and H-2 + air flames was analyzed. Available measurements were interpreted using correlation S-L = S-LO (T/T-o)(alpha). Particular attention was paid to the variation of the power exponent a with equivalence ratio at fixed ( atmospheric) pressure. Experimental data and proposed empirical expressions for a as a funct

Background: Vietnam introduced the Health Care Fund for the Poor in 2002 to increase access to health care and reduce the financial burden of health expenditure faced by the poor and ethnic minorities. It is often argued that effects of financing reforms take a long time to materialize. This study evaluates the short-term impact of the program to determine if pro-poor financing programs can achiev

The Novato L6 chondrite fragmental breccia fell in California on 17 October 2012, and was recovered after the Cameras for Allsky Meteor Surveillance (CAMS) project determined the meteor's trajectory between 95 and 46 km altitude. The final fragmentation from 42 to 22 km altitude was exceptionally well documented by digital photographs. The first sample was recovered before rain hit the area. First

Popular Abstract in Swedish När patienten lämnar sjukhuset och återvänder hem efter en operation för kolorektal cancer (tjocktarm och ändtarm) innebär det en stor omställning. De är inte återställda efter den stora bukoperationen och upplever olika symtom som smärta, tarmbesvär och stor trötthet. Eftersom vårdtiderna blir allt kortare har deras återhämtning bara påbörjats på sjukhuset och de kommeThe overall aim of this thesis is to study the experiences of patients and next of kin with regard to information and information needs after being discharged after colorectal cancer surgery. The aim was also to study factors related to this. Different methods were combined in this explorative study in order to obtain diverse types of data. Patients who had undergone surgery for colorectal cancer

While pattern formation is studied in various areas of biology, little is known about the noise leading to variations between individual realizations of the pattern. One prominent example for de novo pattern formation in plants is the patterning of trichomes on Arabidopsis leaves, which involves genetic regulation and cell-to-cell communication. These processes are potentially variable due to, e.g

Background: Osteoarthritis of the knee involving predominantly the medial tibiofemoral compartment is common in older people, giving rise to pain and loss of function. Many people experience progressive worsening of the disease over time, particularly those with varus malalignment and increased medial knee joint load. Therefore, interventions that can reduce excessive medial knee loading may be be

The incidence of the most common fracture types in Iceland is reported based on individual data from the Reykjavik Study 1967-2008. Time trend is reported for the major osteoporotic fractures (MOS) 1989-2008. This study aims to assess the incidence of all fractures in Iceland, with emphasis on the rate of hip fractures, and compare the incidence with other populations as well as examine the secula

Fractional exhaled nitric oxide is elevated in allergen-provoked asthma. The cellular and molecular source of the elevated fractional exhaled nitric oxide is, however, uncertain.

This paper presents one approach to the absorption and scattering of light from aggregates of primary particles. The primary particles are sphere like and small compared to the wavelength, whereas the aggregate can be large compared to the wavelength. This situation applies to when soot particles formed in flames are measured using methods based on laser light. The method presented in this work, c

Den brittiske filosofen och matematikern Alfred North Whitehead har i ett av sina mer berömda citat sagt att den västerländska filosofihistorien är en serie fotnoter till Platon. På samma sätt kan retorikhistorien sägas vara en serie fotnoter till Aristoteles Retorik. När nu detta inflytelserika verk för första gången finns tillgängligt på svenska kan det vara på sin plats att säga något om detta

ALICE is the heavy-ion experiment at the CERN Large Hadron Collider. The experiment continuously took data during the first physics campaign of the machine from fall 2009 until early 2013, using proton and lead-ion beams. In this paper we describe the running environment and the data handling procedures, and discuss the performance of the ALICE detectors and analysis methods for various physics ob

The purpose of the present study is to determine the feasibility of estimating respiratory information from the built-in pressure sensors of a dialysis machine. The study database consists of simultaneous recordings of pressure signals and capnographic signals from 6 patients during 7 hemodialysis treatment sessions. Respiration rates were estimated using respiratory induced variations in the beat

Imaging is an integral part of an aortic program. Careful preoperative planning is essential to successful evaluation and treatment of aortic pathology. Computed tomography angiography (CTA) is the dominant modality for such preoperative planning. The use of a dedicated workstation for 3D postprocessing is very favorable and is considered mandatory when treating complex aortic pathology. Intraoper

Disaster recovery after the Indian Ocean tsunami in 2004 led to a number of challenges and raised issues concerning land rights and housing reconstruction in the affected countries. This paper discusses the resistance to relocation of fishing communities in Chennai, India. Qualitative research methods were used to describe complexities in the debate between the state and the community regarding re

Popular Abstract in Swedish β-celler producerar insulin som frisätts när blodsockret höjs, t.ex. efter en måltid. Patienter med diabetes saknar de insulinproducerande β-cellerna eller har nedsatt känslighet för insulin. För de patienter som saknar insulin kan det vara svårt att reglera blodsockernivåerna i blodet trots dagliga injektioner med insulin, varför transplanterbara insulinproducerande β-Organogenesis of epithelial organs requires interaction between epithelial and mesenchymal tissues. During pancreas development, mesenchyme-derived structures induce specification, growth and differentiation of pancreatic epithelial cells. For instance, notochord, endothelial cells, and pancreatic mesenchyme are essential for the development of the pancreas. N-cadherin deficient-embryos suffer fro

The liquid argon calorimeter is a key component of the ATLAS detector installed at the CERN Large Hadron Collider. The primary purpose of this calorimeter is the measurement of electron and photon kinematic properties. It also provides a crucial input for measuring jets and missing transverse momentum. An advanced data monitoring procedure was designed to quickly identify issues that would affect

The interactions between DNA and a number of different cationic surfactants, differing in headgroup polarity, were investigated by electric conductivity measurements and fluorescence microscopy. It was observed that, the critical association concentration (cac), characterizing the onset of surfactant binding to DNA, does not vary significantly with the architecture of the headgroup. However, compa

In 1914 Professor Nathan Soderblom was elected archbishop of the Church of Sweden. His consecration took place in Uppsala Cathedral just months after the beginning of World War I. In 1925, he convened an ecumenical meeting in Stockholm that came to shape the ecumenical movement for decades to come. The peace question remained at the heart of his episcopate as long as it lasted. In this article, An
