Lower (negative) bounds on the static electric susceptibility of non-equilibrium cubic crystals [PDF]

arXiv, 2023
We use a classical, microscopic model of point-like dipolarizable entities (a model that is standard in the case of positive polarizability) and investigate its behavior for simple cubic (sc), body-centered cubic (bcc), and face-centered cubic (fcc) crystals with one entity per primitive cell when the static polarizability of the entities is negative ...

A comparative study of circulating tumor cell isolation and enumeration technologies in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells were spiked into donor blood to evaluate the recovery rates of the following circulating tumor cell (CTC) enrichment technologies: CellMag™, EasySep™, RosetteSep™, Parsortix® PR1, and Parsortix® Prototype systems. Each method's advantages and disadvantages are described.

Symptom screening among HIV-infected pregnant women is acceptable and has high negative predictive value for active tuberculosis.

Clinical Infectious Diseases, 2011
We evaluated tuberculosis (TB) screening among 799 human immunodeficiency virus (HIV)-infected pregnant women in India. Eleven (1.4%) had active TB. The negative predictive value of screening using cough, fever, night sweats, or weight loss was 99.3 ...

High-sensitivity cardiac troponin T and copeptin assays to improve diagnostic accuracy of exercise stress test in patients with suspected coronary artery disease [PDF]

, 2014
Background: The average diagnostic sensitivity of exercise stress tests (ESTs) is lower than that of other non-invasive cardiac stress tests. The aim of the study was to examine whether high-sensitivity cardiac troponin T (hs-cTnT) or copeptin ...

Cell‐free and extracellular vesicle microRNAs with clinical utility for solid tumors

Molecular Oncology, EarlyView.
Cell‐free microRNAs (cfmiRs) are small‐RNA circulating molecules detectable in almost all body biofluids. Innovative technologies have improved the application of cfmiRs to oncology, with a focus on clinical needs for different solid tumors, but with emphasis on diagnosis, prognosis, cancer recurrence, as well as treatment monitoring.

Loss Aversion in Recommender Systems: Utilizing Negative User Preference to Improve Recommendation Quality [PDF]

CARS-BDA, at the 12th ACM International Conference on Web Search and Data Mining (WSDM), 2019, 2018
Negative user preference is an important context that is not sufficiently utilized by many existing recommender systems. This context is especially useful in scenarios where the cost of negative items is high for the users. In this work, we describe a new recommender algorithm that explicitly models negative user preferences in order to recommend more ...
