INTRODUCTION: Remote unsupervised cognitive assessments have the potential to complement and facilitate cognitive assessment in clinical and research settings. METHODS: Here, we evaluate the usability, validity, and reliability of unsupervised remote memory assessments via mobile devices in individuals without dementia from the Swedish BioFINDER-2 study and explore their prognostic utility regardi

Many species rely on celestial cues as a reliable guide for maintaining heading while navigating. In this paper, we propose a method that extracts the Milky Way (MW) shape as an orientation cue in low-light scenarios. We also tested the method on both real and synthetic images and demonstrate that the performance of the method appears to be accurate and reliable to motion blur that might be caused

The tunneling dynamics of a magnetic Dy164 quantum gas in an elongated or pancake skewed double-well trap is investigated with a time-dependent extended Gross-Pitaevskii approach. Upon lifting the energy offset, different tunneling regimes can be identified. In the elongated trap and for sufficiently large offset, the different configurations exhibit collective macroscopic tunneling. For smaller o

This paper derives theoretical results for adaptive bias in Doherty amplifiers and presents the design and measurements of an integrated adaptive bias circuit tailored for high peak-to-average high bandwidth signals. Fundamental equations for output power, impedance, and efficiency of the complete Doherty amplifier are derived. Even with ideal transistor models, the Doherty amplifier is fundamenta

Sheep wool was used in the production of textiles across Europe from prehistoric times onwards, but its origins remain unclear. Textiles are rarely preserved in the archaeological record, but further indirect evidence supports their use, such as the study of textile tools, osteology, and terminology. Moreover, new analytical methods, such as protein and DNA analysis, enable the identification of w

Recent years have seen the dominance of neoclassical, marginalist and welfarist schools of Competition Law and Economics being challenged more vigorously than ever [See two major collecting works on fairness in economics in: Fennell and McAdams (2013) and Cappelen and Tungodden (2019)]. Although the core assumptions of the neoclassical school regarding overt reliance on rationality and efficiency

Purpose: We present a comprehensive investigation into the organizational, social, and ethical impact of implementing digital breast tomosynthesis (DBT) as a primary test for breast cancer screening in Italy. The analyses aimed to assess the feasibility of DBT specifically for all women aged 45–74, women aged 45–49 only, or those with dense breasts only. Methods: Questions were framed according to

High racial disparities between Europeans and Africans and high skill premiums are recurrent themes in the literature on inequality in colonial Africa. However, their determinants and effects on inequality remain underexplored. This paper investigates wage inequality, skill premiums, and racial discrimination in British Tanganyika from c. 1920 to 1960. It provides first estimates for wage inequali

This study explores the efficacy of horizontally polarised shear (SH) waves in ultrasonic inspection of concrete-embedded steel liner plates, focusing on corrosion detection. SH-waves are found to significantly improve the localisation and potential dimensional assessment of embedded plate-like structures compared to com- pressional (P) waves, as evidenced by SH C-scans. Anomalies corre- sponding

Young people have been prominent climate advocates globally and they are also becoming increasingly visible in global climate politics. They have participated in Conferences of the Parties (COPs) to the United Nations Framework Convention on Climate Change (UNFCCC) since COP1 in 1995. While recent studies have started to examine the representativeness and participation of youth at the COPs, we sti

Purpose: The purpose of this study was to investigate whether the lesion risk score provided by an AI system is influenced by the selection of exposure parameters. Methods: A breast phantom which contains a lesion, was imaged with digital mammography with different imaging conditions. The tube voltage, the dose level and the anode-filter combination were varied based on an exposure obtained with a

Digital breast tomosynthesis (DBT) has become a standard screening tool for breast cancer. However, its diagnostic performance is still limited compared to contrast-enhanced MRI, especially in women with dense breasts. Ultrafast dynamic contrast-enhanced (UF DCE) MRI and diffusion-weighted imaging (DWI) offer a shorter scanning time than conventional MRI and have shown promise in previous studies.

Many forms of small-size radars suffer from minor clock oscillations due to crystalline impurities in their internal clocks, causing time-varying clock offsets between the transmitter and the receivers. This offset causes a bias and an increased variance in the positioning of close-range targets, limiting the achievable accuracy well beyond the expected estimation limitations. This performance is

This paper develops an adaptive grid two-dimensional (2-D) direction-of-arrival (DOA) estimation technique employing an integrated dictionary framework. In contrast to using a traditional grid over distinct angles, combined angle information atoms are adopted to construct the dictionary, using a SPICE-based noise power estimate to select the active regions. To compensate for off-grid bias effects,

The tumor microenvironment (TME) is composed of various cellular components such as tumor cells, stromal cells including fibroblasts, adipocytes, mast cells, lymphatic vascular cells and infiltrating immune cells, macrophages, dendritic cells and lymphocytes. The intricate interplay between these cells influences tumor growth, metastasis and therapy failure. Significant advancements in breast canc

The importance of reducing environmental impacts has gained speed in the contemporary global context. Stabilization/Solidification (S/S) has become a practical method for handling polluted dredged sediments to make them usable as a construction material. This study aims to evaluate the environmental and economic impacts of a 48,586 m2 port, with stabilized dredged sediment, by focusing on the prod

This report uses highly detailed data from Statcast from the 2015–2023 seasons to explore and identify the key factors influencing on-base percentage in the American top league, Major League Baseball. On-base percentage is simply the percentage of times a player gets on base, and can be achieved in multiple ways. It is an important metric in baseball, as without getting on base, you cannot score.

Prebiotics are complex carbohydrates that are selectively fermented by beneficial gut bacteria, resulting in the production of health-promoting metabolites, such as organic acids like lactic acid, acetic acid, intermediates for butyrate and propionate. Baobab (Adansonia digitata) fruit contains many small seeds, often used for oil production. It’s by-product, baobab seed press cake, is rich in lig
