Self-diffusion of nonspherical particles fundamentally conflicts with effective sphere models

Modeling diffusion of nonspherical particles presents an unsolved and considerable challenge, despite its importance for the understanding of crowding effects in biology, food technology and formulation science. A common approach in experiment and simulation is to map nonspherical objects on effective spheres to subsequently use the established predictions for spheres to approximate phenomena for

Adaptive Event-Triggered Consensus of Multiagent Systems on Directed Graphs

This article systematically studies consensus of linear multiagent systems (MASs) on directed graphs through adaptive event-triggered control. It presents innovative adaptive event-triggered state-feedback protocols with novel composite event-triggering conditions. Two specific designs in terms of different event-triggering conditions and laws of adaption are first discussed for linear MASs on str

Cerebrospinal fluid biomarkers of glial and axonal injury in cervical spondylotic myelopathy

OBJECTIVE Degenerative cervical spondylotic myelopathy (CSM) is a major cause of spinal cord dysfunction with an unpredictable prognosis. Βiomarkers reflecting pathophysiological processes in CSM have been insufficiently investigated. It was hypothesized that preoperative cerebrospinal fluid (CSF) biomarker levels are altered in patients with CSM and correlate with neurological status and outcome.

Performance analysis of daily global solar radiation models in peru by regression analysis

Solar radiation (Rs) is one of the main parameters controlling the energy balance at the Earth’s surface and plays a major role in evapotranspiration and plant growth, snow melting, and environmental studies. This work aimed at evaluating the performance of seven empirical models in estimating daily solar radiation over 1990–2004 (calibration) and 2004–2010 (validation) at 13 Peruvian meteorologic

Stadsdelar som nav för omställning - vad kan vi lära av berättelsen om Augustenborg?

Städer, och framför allt stadsdelar, är nyckelplatser för att tillhandahålla en uppbyggd miljö med direkta kopplingar till sociala och miljömässiga frågor. De ses i allt högre grad som platser för strategiska åtgärder i en omställning till hållbarhet och resiliens, med stora möjligheter till grundläggande samhällsförändringar. Inramningen (så kallad framing) på stadsdelsnivå av problem och lösning

Simulations of light collection in long tapered CsI(Tl) scintillators using real crystal surface data and comparisons to measurement

Simulation results for light transport in long tapered CsI(Tl) crystals using look-up tables (LUTs) are presented. The LUTs were derived from the topography of a polished and a lapped surface of a CsI(Tl) crystal measured with atomic force microscopy. Simulations with different combinations of polished and lapped surfaces were performed, to extract the non-uniformity of light collection depending

Breast cancer in young women. Aspects of heredity and contralateral disease.

Breast cancer is the most commonly diagnosed cancer among women in Sweden, as well as worldwide. In Sweden, 8,288 women were diagnosed with invasive breast cancer in 2019, out of whom approximately 1.5% were younger than 35 years of age. Although breast cancer is relatively uncommon in young women, they tend to be diagnosed with more aggressive tumors at a more advanced stage, and have a poorer pr

Pro-IL-1β Is an Early Prognostic Indicator of Severe Donor Lung Injury During Ex Vivo Lung Perfusion

BACKGROUND: Ex vivo lung perfusion (EVLP) is used to evaluate and recondition extended criteria donor lungs for transplantation. Interleukin-1β (IL-1β) has been identified as a prognostic indicator of nonrecovery during EVLP. This may be an effect of inflammasome activation or cellular necrosis following donation and graft preservation. Delineating the mechanism of IL-1β release is required. METHO

Burkitt Lymphoma International Prognostic Index

PURPOSE: Burkitt lymphoma (BL) has unique biology and clinical course but lacks a standardized prognostic model. We developed and validated a novel prognostic index specific for BL to aid risk stratification, interpretation of clinical trials, and targeted development of novel treatment approaches. METHODS: We derived the BL International Prognostic Index (BL-IPI) from a real-world data set of adu

Environmental degradation, human rights and unsustainable peace in Northern Uganda

The armed conflict between 1986 and 2007 in Northern Uganda had profound impacts on human rights and on the degradation of the natural environment. Unfortunately, peacetime did not revert this. On the contrary, the consolidation of extractive supply chains is bringing environmental deterioration to another scale while social conflicts are emerging among ethnic groups, local communities, families,

Predictive utilities of lipid traits, lipoprotein subfractions and other risk factors for incident diabetes : A machine learning approach in the Diabetes Prevention Program

Introduction Although various lipid and non-lipid analytes measured by nuclear magnetic resonance (NMR) spectroscopy have been associated with type 2 diabetes, a structured comparison of the ability of NMR-derived biomarkers and standard lipids to predict individual diabetes risk has not been undertaken in larger studies nor among individuals at high risk of diabetes. Research design and methods C

Changing trends of contact allergens in Thailand : A 12-year retrospective study

BACKGROUND: Contact allergen prevalences often change. Continual surveillance is necessary to detect trends in sensitization rates and emerging allergens.OBJECTIVE: To identify the prevalence of, and trends in, the positive reactions to each allergen in the baseline series during a 12-year period in Thailand.METHODS: The medical records of 2803 patients who underwent patch testing at the Contact D

Methylchloroisothiazolinone and/or Methylisothiazolinone Contact Allergies in Thailand

BACKGROUND: Methylchloroisothiazolinone, in combination with methylisothiazolinone (MCI/MI), and MI alone are common preservatives. The incidences of MCI/MI and MI-alone contact allergies have risen markedly worldwide, leading to changes in their use in products.OBJECTIVES: The aim of the study was to determine the incidences of positive patch test reactions and factors associated with MCI and/or

Contact allergy to hair cosmetic allergens in Thailand

BACKGROUND: Hair cosmetics such as hair dyes, bleaching, waving, and cleansing products are composed of numerous chemical ingredients. Allergic reactions to these contact allergens, other than p-phenylenediamine, are rarely reported.OBJECTIVES: To study the incidence of patch test reactions to hair cosmetic allergens and identify the factors associated with hair cosmetic allergy in Thailand.METHOD

Water damages in HVAC, tap water and sewage systems in cold climates

Water damages in buildings in the Nordic countries results in costs amounting to several billion Euros each year as well as a great deal of unpleasantness. The vast majority of the water damages cost in Sweden is caused by leaks from buildings services in the form of piping such as tap water, sewage, drainage and heating, as well as through insufficiently waterproof layers in wet rooms. The econom
