This record presents Release 1.0 of the IPCRF Version 1.2 Public Historical Back-Test Evidence Collection, a coordinated set of four retrospective case studies evaluating the Integrated Project Controls and Risk Forecasting Framework (IPCRF) using publicly available historical records from major U.S. transit capital projects.
The collection applies the frozen IPCRF Version 1.2 methodology without retrospectively changing thresholds, weights, formulas, or action bands to fit known project outcomes. Each case reconstructs only those indicators that can be supported by contemporaneous public records, while unavailable or definition-incompatible variables are retained as unavailable rather than inferred or fabricated.
The four cases provide complementary evidence. Case Study 1, involving NYCT ADA Station Improvements at 149 St–Grand Concourse and Tremont Av, identified a Critical Finish Slippage signal before the original baseline completion date and before substantially greater schedule deterioration became evident. Case Study 2, involving Dulles Corridor Metrorail Phase 2, demonstrated cross-domain divergence in which cost indicators remained comparatively stable while schedule, change, and contractor-performance indicators showed materially greater stress. Case Study 3, involving East Side Access / Grand Central Madison, produced auditable cost, schedule, float, access, and interface warning signals while also exposing an important Version 1.2 missing-data governance ambiguity that prevented promotion of the available indicator results into formal complete domain scores. Case Study 4, involving the Canarsie Tube / L Project Tunnel Rehabilitation, serves as a favorable-outcome control case and produced predominantly Low or Watch results on the reconstructable indicators rather than severe warnings.
Taken together, the four cases provide an initial real-world empirical evidence base for evaluating the behavior of selected IPCRF indicators across materially different project-delivery conditions. The collection supports examination of indicator sensitivity, cross-domain warning patterns, schedule-recovery margin, constructability and interface constraints, missing-data discipline, and potential discrimination between adverse and favorable outcomes.
This collection does not establish universal predictive validity, calibrated false-positive or false-negative rates, causal accuracy, agency-specific calibration, or full six-domain operational validation of IPCRF. Complete Project Delivery Risk Scores (PDRS) and Forecast Confidence Scores (FCS) are not claimed where the Version 1.2 data-completeness requirements cannot be satisfied using the available public record.
Each case study is preserved as a separate Zenodo research object with its own DOI, technical report, reproducibility materials, machine-readable data, source-provenance documentation, and README. This umbrella record provides the collection-level context and links the four case studies as a single version-controlled historical evidence series.

This work examines the needs of family caregivers of older adults with dementia, with particular attention to caregiver burden, emotional well-being, quality of life, and the challenges of balancing paid work with caregiving responsibilities.
The study involved 50 family caregivers and 50 people with dementia aged over 65. It explored caregivers’ experiences through measures of burden, depression, anxiety, quality of life, and social adjustment, alongside assessments of the care recipients’ cognitive status and ability to carry out daily activities.
The findings draw attention to the burden experienced by family caregivers, particularly those who also have paid employment. By considering both caregivers’ well-being and the needs of the people they care for, this work offers a basis for developing support tailored to families living with dementia.

The enhanced oil recovery mechanisms in fractured reservoirs are complex and not fully understood. It is technically challenging to quantify the related driving forces and their interaction in the matrix and fractures medium. Gravity and capillary forces play a leading role in the recovery process of fractured reservoirs. This study aims to quantify the performance of EOR methods in fractured reservoirs using dimensionless numbers. A systematic approach consisting of the design of experiments, simulations, and proxy-based optimization was used in this work. The effect of driving forces on oil recovery for water injection and several EOR processes such as gas injection, foam injection, water-alternating gas (WAG) injection, and foam-assisted water-alternating gas (FAWAG) injection was analyzed using dimensionless numbers and a surface response model. The results show that equilibrium between gravitational and viscous forces in fracture and capillary and gravity forces in matrix blocks determines oil recovery performance during EOR in fractured reservoirs. When capillary forces are dominant in gas injection, fluid exchange between fracture and matrix is low; consequently, the oil recovery is low. In foam-assisted water-alternating gas injection, gravity and capillary forces are in equilibrium conditions as several mechanisms are involved. The capillary forces dominate the water cycle, while gravitational forces govern the gas cycle due to the foam enhancement properties, which results in the highest oil recovery factor. Based on the performed sensitivity analysis of matrix–fracture interaction on the performance of the EOR processes, the foam and FAWAG injection methods were found to be more sensitive to permeability contrast, density, and matrix block highs than WAG injection.

Computational functionalism leaves open what fixes the character of experience, which process possesses it, how it causes behavior, and how a subject can know it. This paper defends the centered-knowledge thesis: for a phenomenal center, phenomenal character is identical to the complete organization of the distinctions available at that causal locus, their access relations, and the transitions they can govern. Because the same centered states constitute phenomenal differences and produce comparison, memory, judgment, report, and action, the thesis explains epistemic contact with one’s experience, answers the causal demand of the meta-problem, excludes functionally identical zombies, and derives the explanatory gap from the exclusivity of occupation: to occupy one complete state is to occupy no other. Organizational invariance, substrate independence, and multiple realizability follow from the identity rather than entering as separate principles, and the substitution level turns them into a criterion for replacement, emulation, and upload fidelity. Causal access individuates the subject, explains binding, unity, and privacy, and permits nested and overlapping centers. The same boundary that individuates a subject also limits what it can know: present centered knowledge underdetermines history, program, substrate, and world, and physics appears to any observer as structure and dynamics because only these cross a point of view’s boundary. The identity’s natural limit, advanced as a separable hypothesis, is that phenomenality begins with the first causally usable distinction. Comparisons with global-workspace, higher-order, and integrated-information theories yield contrasting attributions, and tests are proposed. Experience is what structured knowledge is like for the process that possesses it.
