title: Empirical Validation of Fractal Time Coherence in the GAL-2™ System — 24-Hour Continuous Run (San Juan, PR, Nov 2025)

description: This dataset presents the verified 24-hour continuous operation of the GAL-2™ (Global Alignment Layer | Fractal Time) system conducted in San Juan, Puerto Rico, in November 2025.

 

The experiment demonstrates empirical coherence between digital time and solar-based UT1 references without reliance on NTP, GNSS, or external atomic clocks. The system sustained drift-free performance throughout a 24-hour period, achieving 0 ms mean drift and ±0.2 ms variance, aligning with IERS ΔUT1 benchmarks.

 

Dataset contents:

• Full drift log (drift_logs/gal2_drift_log.jsonl)

• Integrity proof (sha256.txt)

• Run summary (summary_20251103T183100Z.txt)

• Endpoint specifications (README_Proof_of_24h_Run.txt)

 

Purpose:

This release supports independent verification and simulation by external researchers and organizations (e.g., xAI) studying drift correction, high-precision synchronization, and AI-coherent timing models.

 

Public API reference (for simulation):

/status → health info (public)

/time → drift-corrected fractal timestamp (requires API key)

 

Result:

Verified fractal coherence between internal τ·Φ·Ψ³ alignment and terrestrial solar time.

 

Keywords: fractal time, coherence, time synchronization, leap seconds, ΔUT1, drift correction, precision timing, AI systems, GAL-2, San Juan Puerto Rico.

description: This verified dataset presents the outcomes of the GAL-2™ Solstice 2025 Stress Test—a 30-minute continuous alignment run executed through the AWS-hosted GAL-2™ (Global Alignment Layer | Fractal Time) API.

 

The primary objective was to evaluate GAL-2™’s real-time drift correction and stability under simulated solstice conditions (UTC emulation: 2025-12-21T00:00:00Z), in preparation for independent laboratory replication.

 

The system maintained continuous alignment for 1,800 seconds (approximately 30 minutes) with 1 Hz sampling and zero error accumulation, demonstrating a stable fractal-based time reference that surpasses the limitations of NTP/PTP.

title:  Machine learning predictors for chronic lymphocytic leukemia (CLL) patients obtaining benefit from the addition of obinutuzumab (O) to acalabrutinib (A)

description: Chronic Lymphocytic Leukemia (CLL) is a type of cancer that affects the blood and bone marrow, commonly seen in older adults. It involves the slow accumulation of white blood cells, leading to impaired immunity and other complications. Traditionally, treatment options include chemotherapy and targeted therapies (cancer treatments that use drugs to precisely identify and attack specific types of cancer cells). Chemotherapy works by using powerful drugs to kill rapidly dividing cells like cancer cells. Targeted therapies work by attacking specific features of cancer cells, like proteins or genes that help them grow, while causing less harm to normal cells.

Recent clinical studies, particularly the ELEVATE-TN trial, have shown that combining the targeted therapies acalabrutinib and obinutuzumab provides significant progression-free survival (PFS - how long a patient lives with the cancer without it getting worse) benefits compared to other treatments. However, while this combination has shown promise, adding obinutuzumab also introduces additional side effects. Prior analyses sought to identify which CLL patient groups benefit most from this combination but did not consider all potential genetic factors.

This study aims to identify which CLL patients benefit the most from combining acalabrutinib with obinutuzumab. By using machine learning—a type of artificial intelligence that finds patterns in large datasets—the study will analyze clinical and genetic information to create a model that predicts treatment response. This will help doctors decide whether adding obinutuzumab is the right choice for individual patients, reducing unnecessary side effects and improving treatment outcomes.

To conduct this research, data from past clinical trials will be analyzed. These trials included patients who received acalabrutinib, either alone or with obinutuzumab. The study will use machine learning methods to examine patient characteristics such as age, blood test results, and genetic markers (specific changes in a patient’s genes, such as IGHV and TP53 mutations, that may affect how their cancer behaves or responds to treatment). By testing the model on different parts of the data, researchers will ensure it provides reliable predictions. The key outcomes measured will be PFS and overall survival (OS - how long people live after being diagnosed with CLL, regardless of the cause of death).

Ultimately, this research seeks to develop an "Optimal Responder Profile" - a way to determine which patients are most likely to benefit from the combination therapy. This will help improve personalized treatment approaches for CLL, leading to better patient care and fewer unnecessary side effects.

description: "This dataset contains raw and processed results from a series of usability and performance evaluations conducted on the Virtual Patient Simulator (VPS) tutor and student platforms. The data were collected across three main strands: (1) student usability tests, including pre- and post-questionnaires on user experience and interface interaction; (2) tutor usability tests, capturing perceptions of system usability, digital tool familiarity, and teaching alignment; and (3) student performance tests, comprising pre- and post-assessment scores from controlled learning experiments comparing VPS against traditional instruction. Altogether, the dataset provides quantitative measures (e.g., Likert-scale responses, test scores) and qualitative feedback (e.g., reported difficulties and suggestions for improvement), enabling replication of reported analyses and secondary research on educational technology usability and effectiveness."
