As physical distancing is a core measure of containing the spread of COVID-19, this pandemic is a crisis that has uprooted social interaction. While current research mainly focuses on crises as a challenge for entrepreneurial ventures and potential regulatory response mechanisms, we complement this research by addressing the question of how crises in general—and COVID-19's physical distancing meas

STUDY DESIGN: We retrospectively analyzed Spinal Instability Neoplastic Score (SINS) in 110 patients with prostate cancer operated for metastatic spinal cord compression (MSCC). OBJECTIVE: We aimed to investigate the association between SINS and clinical outcomes after surgery for MSCC in patients with prostate cancer. SUMMARY OF BACKGROUND DATA: The SINS is a useful tool for assessing tumor-relat

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

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

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.

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

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

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 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

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

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

COVID-19 pandemic has showed the world more than ever the relevance of green and public spaces for the fulfilment of human rights in urban settings. The role they will play in post-pandemic socio-environmental recovery will be central, particularly in highly densified cities of the Global South.

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,

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

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

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
