Achieving QoS-based broadband wireless access means a lot for the people living in the information age. WiMAX has evolved now into a stage that we can say it can meet this demand. From among the various fields to study in this domain, call admission and scheduling are the strongest tools in our hand to ensure QoS. On the other side, exploiting mesh topology is a good technique to increase the netw
Biogenic silica (BSi) is used as a proxy by soil scientists to identify biological effects on the Si cycle and by palaeoecologists to study environmental changes. Alkaline extractions are typically used to measure BSi in both terrestrial and aquatic environments. The dissolution properties of volcanic glass in tephra deposits and their nanocrystalline weathering products are hypothesized to overla
Background: Irreversible electroporation (IRE) is a local tumor treatment. Thin needles are placed percutaneously around the tumor under ultrasound guidance. Short pulses of direct current sent through the tissue irreversibly increase cell membrane permeability leading to cell death. We report a phase I study assessing the safety of ultrasound guided percutaneous IRE in patients with localized pan
PURPOSE: To determine whether reproductive and hormonal risk factors for breast cancer associate with mammography attendance. METHODS: We linked data from the Malmö Diet and Cancer Study to the Malmö mammography register (Sweden, 1992-2009). We analyzed 11,409 women (age 44-72) who were free of breast cancer at study entry and a total of 69,746 screening invitations. Generalized Estimating Equatio
Detection turning points in unimodel has various applications to time series which have cyclic periods. Related techniques are widely explored in the field of statistical surveillance, that is, on-line turning point detection procedures. This paper will first present a power controlled turning point detection method based on the theory of the likelihood ratio test in statistical surveillance. Next
The purpose of the study was to explore the role of the physical environment for creative employees. The results are based on interviews with office-working digital artists. The physical work environment was considered to offer three types of support for creative work for the participants: functional, psychosocial, and inspirational. Creative processes would find better breeding ground if function
Objectives: To evaluate screening for retinopathy of prematurity (ROP) in Sweden and to investigate possible modifications of the present screening guidelines. Methods: Infants in Sweden with a gestational age (GA) of 31 weeks + 6 days or less are screened for ROP. Data from the Swedish national register for ROP (SWEDROP) during 2008 and 2009 were extracted and compared with a national perinatal q
The purpose of this paper is to present the optimal number of windows and window lengths using multiple window spectrogram for estimation of non-stationary processes with shorter or longer duration. Such processes could start in the EEG as a result of a stimuli, e.g. steady-state visual evoked potentials (SSVEP). In many applications the Welch method is used with standard set-ups for window length
Agricultural intensification in Europe has affected farmland bird populations negatively, both during summer and winter. Although the migratory period poses separate challenges on birds than breeding and wintering, the consequences of farming practices for birds during migration remain poorly investigated. We monitored abundance and species richness of migratory birds in autumn at matched pairs of
AIMS AND OBJECTIVES: To describe the patients' retrospective experiences of the information and support they received while on the heart or lung transplant waiting list. BACKGROUND: Patients differ in the way that they cope with the time spent waiting for a heart or lung transplant. Patients must already before the transplantation be taught about a new lifestyle, risk factors, medication, food res
Diabetes is a growing global problem, with hundreds of millions of people living with the disease worldwide. Diabetes can be divided into two major subtypes, autoimmune type 1 diabetes (T1D), and type 2 diabetes (T2D), which has stronger causal links in obesity, lifestyle, and age. Although immunity and inflammation are clearly defined in T1D, it is also understood that inflammation has a role in
Adoptive transfer of regulatory T cells (T(regs)) has been proposed for use as a cellular therapy to induce transplantation tolerance. Preclinical data are encouraging, and clinical trials with T(reg) therapy are anticipated. In this study, we investigate different strategies for the isolation and expansion of CD4(+) CD25(high) CD127(low) T(regs) from uraemic patients. We use allogeneic dendritic
Background Parathyroid surgery is an appropriate alternative for renal hyperparathyroidism (rHPT) in patients in whom medical therapy fails. European morbidity and outcome data for clearly defined cohorts, potentially reflecting contemporary clinical practice, remain scarce. Method Data were extracted from the EUROCRINE® database on all operations for secondary rHPT between 1 January 2015 and 31 D
Collective action by small-scale farmers can contribute significantly toward rural development. One important aspect that remains relatively neglected, especially in research set in Africa, is the role of farmer collectives in political processes. We study the local-level dynamics of a farmer-based organization mobilizing for agroecology and food sovereignty in Uganda. Through qualitative, collabo
The real-time interface chemistry between the lithium cobalt oxide (LCO) working electrode and the LiClO4/propylene carbonate (PC) electrolyte is investigated during lithiation/delithiation using dip-and-pull ambient pressure photoelectron spectroscopy (APXPS). The APXPS results appear to exhibit the seldom discussed Co2+ state in the LCO structure, where the operando measurements indicate electro
Global water scarcity requires innovative treatment solutions. This presentation explores three membrane-based concepts advancing from idea to pilot scale: stormwater harvesting with micro-/ultrafiltration (MF/UF), direct membrane filtration (DMF) for wastewater treatment, and a hybrid forward osmosis (FO), membrane distillation (MD), and nanofiltration (NF) system for seawater desalination.The EU
IntroductionGlobal water scarcity requires new approaches for water treatment. Membrane technology has proven itself as key technology for water treatment from seawater desalination with reverse osmosis to wastewater treatment with membrane bioreactors. In this presentation three new water treatment concepts based on membrane technology and their development from idea to pilot scale testing will b
Boron-doped diamond (BDD) films were synthesized via microwave plasma-enhanced chemical vapor deposition at five boron-to-carbon ratios to investigate dopant effects on perfluorooctanoic acid (PFOA) electrooxidation and electrode stability. Raman spectroscopy revealed that excessive boron (≥10k ppm) produced sp²-rich regions indicative of structural degradation. Electrodes optimized at ∼10k ppm bo
Acute hemolytic transfusion reaction (AHTR) is a rare but life-threatening complication of transfusion. We herein report a case of anti-Jkb IgM-related AHTR. Two hours after an 80-year-old man with myelodysplastic syndrome received a packed red blood cell (RBC) A+/Rh-/Jkb+/c- transfusion, he developed acute respiratory failure and a fever. Although he had tested negative in routine screening tests
Understanding the structure of metal-ligand complexes is essential for catalyst design, materials development, and biochemical modeling. Metal carbonyls are especially relevant due to their diverse structures and electronic features. Here, we benchmarked seventeen density functionals (B3LYP, BP86, CAM–B3LYP, M06, M06L, PBE, PBE0, r2SCAN, r2SCAN–3c, revPBE, revTPSS, RPBE, TPSS, TPSS0, TPSSh, (Formu
