Heuristic Rules for the Dynamic Pricing Problem

Organizations and Markets in Emerging Economies, 2023
This paper is devoted to the development of heuristics for the dynamic pricing problem. A discrete time model of dynamic pricing on the fixed time horizon is proposed. It is applicable to products that satisfy two properties: 1) product value expires at

Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

Molecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

Research on the Causes and Countermeasures of the Pink Tax Phenomenon in the Context of Big Data [PDF]

SHS Web of Conferences
Although gender-based price discrimination (“Pink Tax”) has gained significant attention, existing research lacks a thorough exploration of the underlying mechanisms driving this phenomenon, particularly from the perspective of informational gaps.

Barter for price discrimination [PDF]

International Journal of Industrial Organization, 2004
We study barter as a discriminatory instrument in oligopoly with asymmetric information. Buyers (producers of final goods) differ in the quality of their products. Sellers (producers of inputs) use barter as a screening device: the higher quality buyers pay in cash while the lower quality ones pay in kind. Barter, identified with non-monetary contracts

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

RaMBat: Accurate identification of medulloblastoma subtypes from diverse data sources with severe batch effects

Molecular Oncology, EarlyView.
To integrate multiple transcriptomics data with severe batch effects for identifying MB subtypes, we developed a novel and accurate computational method named RaMBat, which leveraged subtype‐specific gene expression ranking information instead of absolute gene expression levels to address batch effects of diverse data sources.

Parallel imports, innovations and national welfare: The role of the sizes of the income classes and national markets for health care. [PDF]

, 2008
This paper shows that regardless of any intra-country income differences, parallel imports result in a lower level of health-care innovation but, contrary to popular as well as conventional theoretical wisdom, a lower price in the Third World compared to

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...
