Strategic Prototyping Technology Adoption in Startups: Framework, Challenges, and Opportunities

Startups use prototyping to develop and validate their products and business models. For startups, it is important to have a good knowledge of relevant adoption factors, to make decisions regarding which prototyping technology to adopt. In this article, we identify such factors based on our practical experiences of startups in various industries. We define a research framework, describe challenges

Management of urban floods based on tolerable consequences in an uncertain future

Precipitation is intrinsically associated with high uncertainty, which is exacerbated exponentially over time—especially concerning climate change. However, the current design practice in urban drainage infrastructure remains firmly bound to deterministic assumptions regarding the design load. This approach is too simplified—focusing only on the return period of the design event—and ignores the co

Frame Analysis

Erving Goffman’s book Frame Analysis (1974) differs from several of his other texts (e.g. the praised books The Presentation of Self in Everyday Life, Encounters, Stigma and Asylums) in that it is probably read because of Goffman’s reputation rather than because it is considered to have an indispensable message. Frame Analysis doesn’t seem to be a book that you must read. It lacks the heuristic ch

A Comparison of TDD and FDD Massive MIMO Systems Against Smart Jamming

Frequency division duplex (FDD) massive multiple-input multiple-output (MIMO) systems introduce a large overhead in downlink channel estimation in contrast to the time division duplex (TDD) mode. This overhead results in a considerable spectral efficiency (SE) gap between the FDD and TDD modes. In this paper, we consider the performance of the TDD and FDD massive MIMO systems with a spatially corr

Identification of a Catalytic Nucleophile-Activating Network in the endo - α -N- Acetylgalactosaminidase of Family GH101

Bifidobacterium longum endo-α-N-acetylgalactosaminidase (GH101), EngBF, is highly specific toward the mucin Core 1 glycan, Galβ1-3GalNAc. Apart from the side chains involved in the retaining mechanism of EngBF, Asp-682 is important for the activity. In the crystal structures of both EngBF and EngSP (from Streptococcus pneumoniae), we identified a conserved water molecule in proximity to Asp-682 an

Predicting the Redshift of Gamma-Ray Loud AGNs Using Supervised Machine Learning. II

Measuring the redshift of active galactic nuclei (AGNs) requires the use of time-consuming and expensive spectroscopic analysis. However, obtaining redshift measurements of AGNs is crucial as it can enable AGN population studies, provide insight into the star formation rate, the luminosity function, and the density rate evolution. Hence, there is a requirement for alternative redshift measurement

Human well-being and per capita energy use

Increased wealth and per capita energy use have transformed lives and shaped societies, but energy poverty remains a global challenge. Previous research has shown positive relationships among metrics of health and happiness and economic indices such as income and gross domestic product and between energy use and human development. To our knowledge, however, no comprehensive assessment has examined

Asking about Social Circles Improves Election Predictions Even with Many Political Parties

Traditionally, election polls have asked for participants' own voting intentions. In four elections, we previously found that we could improve predictions by asking participants how they thought their social circles would vote. A potential concern is that the social-circle question might predict results less well in elections with larger numbers of political options because it becomes harder to ac

Amplified wintertime Barents Sea warming linked to intensified Barents oscillation

In recent decades, the Barents Sea has warmed more than twice as fast as the rest of the Arctic in winter, but the exact causes behind this amplified warming remain unclear. In this study, we quantify the wintertime Barents Sea warming (BSW, for near-surface air temperature) with an average linear trend of 1.74 °C decade-1 and an interdecadal change around 2003 based on a surface energy budget ana

Quantitative evaluation of the tibiofemoral joint cartilage by T2 mapping in patients with acute anterior cruciate ligament injury vs contralateral knees : results from the subacute phase using data from the NACOX study cohort

Objective: Immediate cartilage structural alterations in the acute phase after an anterior cruciate ligament (ACL) rupture may be a precursor to posttraumatic osteoarthritis (PTOA) development. Our aim was to describe changes in cartilage matrix in the subacute phase of the acutely ACL-injured knee compared to the contralateral uninjured knee. Design: Participants (n = 118) aged 15–40 years with a

Freely available artificial intelligence for pelvic lymph node metastases in PSMA PET-CT that performs on par with nuclear medicine physicians

Purpose: The aim of this study was to develop and validate an artificial intelligence (AI)-based method using convolutional neural networks (CNNs) for the detection of pelvic lymph node metastases in scans obtained using [18F]PSMA-1007 positron emission tomography-computed tomography (PET-CT) from patients with high-risk prostate cancer. The second goal was to make the AI-based method available to

Effects of Increasing Salinity by Drip Irrigation on Total Grain Weight Show High Yield Potential of Putative Salt-Tolerant Mutagenized Wheat Lines

Twenty-three lines from a mutagenized Bangladeshi BARI Gom-25 wheat population that included previously identified salt-tolerant lines, and the BARI Gom-25 control variety, were cultivated in a drip-irrigated salinity test field at Salt Farm Texel, Netherlands, to assess their performance during salt stress in European climatic conditions. Lines were tested at irrigation salinity levels of 1, 4, 8

Outcomes of relapsed/refractory diffuse large B-cell lymphoma and influence of chimaeric antigen receptor T trial eligibility criteria in second line—A population-based study of 736 patients

Several recently published trials investigate novel therapies for relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL). To estimate the benefit of these therapies in the real-world setting, comprehensive data on patients treated in clinical routine are needed. We report outcomes for 736 R/R DLBCL patients identified among all curatively treated DLBCL patients in Sweden in the period 2007–
