A Top-Down Method for Estimating the Market Value of Creative Work to AI Systems: Evidence from the Reddit-Google Licence

Google reportedly pays Reddit \$60 million a year for data access covering both model pre-training and the grounding of live answers. This paper uses that disclosed price, together with a top-down valuation method emerging from the data-economics literature, to estimate the share...

Late diagnosis of OHVIRA syndrome — case series and literature review

OBJECTIVES: The aim of this study was to present three adult cases of obstructed hemivagina, and ipsilateral renal anomaly (OHVIRA) syndrome diagnosed in different gynecological centers in Poland. The clinical presentations, diagnostic imaging, surgical treatment, and outcomes we...

FGF12, a FoxO1-downregulated gene, promotes the survival of trophoblast cells in gestational diabetes mellitus: a preliminary study

OBJECTIVES: Gestational diabetes mellitus (GDM) is a common pregnancy complication associated with adverse maternal and fetal outcomes. Although the prevalence of GDM is high, the molecular mechanisms involved in GDM-related placental dysfunction remain poorly understood. This st...

Laparoscopic suture pectopexy for advanced stage vaginal vault prolapse: a feasible alternative to synthetic mesh (Biyik’s modification)

OBJECTIVES: The aim of the study is to evaluate the safety and feasibility of using a nonabsorbable suture instead of synthetic mesh in laparoscopic pectopexy. MATERIAL AND METHODS: Women diagnosed with symptomatic Pelvic Organ Prolapse Quantification (POP-Q) stage III and IV vag...

Unraveling the hormonal causality in postpartum depression: findings from a two-sample Mendelian randomization study

OBJECTIVES: Postpartum depression (PPD) profoundly affects maternal health and disrupts mother-infant bonding, with lasting effects on infant development. The causal roles of hormones that change most dramatically during the perinatal period, including estradiol, cortisol, and pr...

The expression of lysophosphatidic acid and C-reactive protein in the course of the vulvar squamous cell carcinoma and the vulvar lichen sclerosus

OBJECTIVES: In the course of the study the differences regarding both C-reactive protein immune-expression and Lysophosphatidic Acid immune-expression between the stages and histologic grades of the vulvar cancer and the differences between the group of patients diagnosed with li...

Ovarian volume in premenarchal girls — a reference guide for routine pelvic ultrasonography

OBJECTIVES: To provide reference values for ovarian volume in healthy premenarchal girls for use in routine pelvic ultrasonography interpretation. MATERIAL AND METHODS: A retrospective analysis of 170 healthy girls aged 0 to 11 years who underwent pelvic ultrasound examinations b...

Comparative performance of four risk of malignancy indices (RMI) in predicting ovarian malignancy: a large retrospective cohort study

OBJECTIVES: To compare the predictive performance of four risk of malignancy index (RMI) in patients with adnexal masses. MATERIAL AND METHODS: This retrospective study included 703 patients who underwent surgery for adnexal masses. Preoperative ultrasonographic findings, menopau...

Evaluation of the INTERGROWTH-21st fetal growth standards in a single-center cohort of uncomplicated pregnancies in Poland

OBJECTIVES: To evaluate the applicability of the INTERGROWTH-21st prescriptive fetal growth standards for thirdtrimester biometry and estimated fetal weight (EFW) assessment in a Polish population. MATERIAL AND METHODS: This retrospective single-center cohort study included 594 u...

Arithmetic methods for exploring archaeological source provenance using geochemistry – a short reply

In this reply, we respond to the comment by Pearce and colleagues regarding our recently proposed arithmetic method for assessing geochemical similarity between lithic artefacts and potential source outcrops. We thank the authors for their critique, which highlights several impor...

Epistemic Payoff Dependence: Roko's Basilisk and the Structure of Self-Referential Threats

Roko's Basilisk is a thought experiment about a future superintelligent Artificial Intelligence (AI) that punishes those who were aware of its possible creation but did not contribute to building it. Most existing analyses interpret it as a problem of decision theory or rationali...

Time Field Theory (TFT): Axiomatic Foundation, Dynamics and Classical Gravitational Tests — Version 2.0 (Perfect Circle Postulate and Periodic Self-Consistency Ontology)

This paper presents Version 2.0 of Time Field Theory (TFT), which reconstructs the entire axiomatic foundation from the kinematic level to the ontological level of periodic self-consistency and the perfect circle postulate. Starting from three core axioms of stable periodic oscil...

The MOND Acceleration Scale as a de Sitter Curvature Scale: Gauged SO(4,1) Gravity Reduces a0 = c^2 sqrt(Lambda/32pi) to a Single Free Number

Galaxy dynamics organize around an acceleration scale a0 ~ 1e-10 m/s^2 that numerically coincides with c*sqrt(Lambda) and cH0. This paper develops the hypothesis that the coincidence is structural -- that a0 is a de Sitter curvature scale, a0 = c^2*sqrt(Lambda/32pi) = (c/2)*sqrt(...

Quantitative verification of treatment delivery accuracy utilizing deep inspiration breath hold (DIBH) for left-sided breast irradiation

Abstract Purpose: To assess the treatment delivery accuracy of left-sided breast irradiation using the deep inspiration breath hold (DIBH) technique via Gamma passing rate (GPR) analysis. Methods: Thirteen patients with left-sided breast cancer who had previously undergone volume...

Comparison of TG-43 and advanced collapsed cone engine dose calculations in cervical HDR brachytherapy with plastic and metallic applicators

Abstract Purpose: Conventional brachytherapy treatment planning based on the TG-43 formalism assumes a homogeneous water medium and neglects the effects of applicator materials and tissue heterogeneities. This study aimed to investigate the clinical impact of Model-Based Dose Cal...

Comparison and Reliability of Inertial Sensor-Based Gait Data Acquisition Across Three Shank-Mounted Smartphone Configurations in Older Adults

About the Project This dataset was collected within the Spine Interactive project. The aim was to examine whether IMU time series recorded with three different smartphones are comparable during 2-minute treadmill walking trials in older adults. The devices were an iPhone 15 Pro,...

Recombination drives genome evolution in outbreak-related Legionella pneumophila isolate

Legionella pneumophila is a strictly environmental pathogen and the etiological agent of legionellosis. It is known that non-vertical processes have a major role in the short-term evolution of pathogens, but little is known about the relevance of these and other processes in envi...

Referral Mechanics: A Framework for Communication and Reality

Referral Mechanics presents a detailed approach to referral within a Two-Track Language Model, where words, ideas, and mental images operate as a self-contained script, independent of human intent to access their core counterparts. Human intent, social conditioning, and props ste...

Negative Dwell Times as Resolvent Derivatives: A Structural Operator-Theoretic Explanation of 𝑻𝑻=𝒕𝒈

A structural operator-theoretic account of negative group delays and post-selected excitation times in resonant atomic media. Within a scalar Lorentzian propagation model, the excitation time and the optical delay are shown to be parameter derivatives of the same frequency-resolv...
