Barangay San Antonio 1, Noveleta, Cavite, still relies on manual and fragmented channels for incident reporting, emergency communication and response coordination. Such practices may hinder information flow, make it harder to check reports and limit the capability of barangay officials to see affected areas in emergency situations. This project developed Respondr, a geo-tagged barangay reporting and disaster response system to provide a localized web and mobile platform for residents, barangay officials, and administrators. Respondr lets residents send incident reports with description, photos and saved coordinates; track report status; view alerts and announcements; and view community locations on a map. Barangay officials can view incoming reports, update the lifecycle of the incident, add entries for response, manage alerts and announcements, monitor SMS logs, view analytics and manage vital mapped locations such as evacuation centers and community landmarks. Role-based access controls allow administrators to manage users and monitor system activity. The system was evaluated in terms of automated backend API tests, a full-stack manual regression matrix, production smoke and performance checks, a backend security review and a Technology Acceptance Model (TAM) user evaluation. Manual regression matrix completion had 100 passed cases out of 100 and automated backend API integration suite had 31 passed tests out of 31. Fifteen (15) participants took part in the TAM evaluation, 10 residents and 5 barangay officials. The results indicated high acceptance with a mean overall TAM of 4.81. These results show that Respondr met the functional requirements tested and the system was found useful and easy to use by users in enhancing the reporting of incidents, communication during disasters, and coordination of responses at the barangay level.

Topology-Selective Physical Memory: When Environmental History Acquires Chemical Consequences

Biological information is usually studied in systems that already possess replication, templating, or heredity. This work asks an earlier question: can a nonliving physical substrate selectively retain information about its environmental history, and can that retained history subsequently alter chemistry?
This paper introduces topology-selective physical memory (TSPM): the differential persistence of information about environmental history produced by the interaction architecture of a physical system. Using the 32-state, five-site energetic substrate of the Adaptive Mineral Encoding Framework (AMEF), environmental histories are written into physical state distributions and allowed to relax under explicit single-site Metropolis dynamics.
The model produces a four-stage architecture:
WRITE → FILTER → PRESERVE → EXECUTE
Interaction topology predicts which environmental directions persist. The favored (+,−,+,−,+) environmental direction is nearly collinear with the dominant cooperative eigenmode of the pairwise interaction matrix (|cos θ| = 0.9967). Across a 2,112-condition orientation sweep, coupling selectively enhances or suppresses memory depending on environmental direction rather than generically increasing persistence.
When favored and disfavored components are written simultaneously, differential relaxation progressively changes the composition of retained information. The ratio of their fractional retention reaches 2.07 after five Monte Carlo steps and 3.86 after ten, demonstrating topology-dependent filtering of a mixed environmental history.
A synthetic downstream readout further shows that retained historical information can alter later outcomes under identical external conditions. Scrambling the association between environmental history and retained physical state abolishes downstream historical information, demonstrating that the modeled effect depends on the history-state correspondence rather than heterogeneous state occupancy alone.
TSPM does not claim that physical memory, chemical memory, or mineral-carried environmental history are themselves new phenomena. Rather, it proposes a specific mechanism by which the internal interaction topology of a nonliving substrate can select which components of environmental history survive relaxation and remain available to influence subsequent chemistry.
Greigite (Fe₃S₄) is treated as a candidate experimental substrate rather than a demonstrated implementation. The numerical model uses DFT-informed toy parameters and dimensionless Monte Carlo time; the downstream chemical readout is hypothetical. The work therefore establishes a theoretical mechanism and falsifiable experimental prediction, not empirical demonstration of TSPM in greigite.
This study is a successor to the original Adaptive Mineral Encoding Framework and develops a distinct theory of selective physical memory rather than superseding the earlier work.
Central proposition: Information begins when history acquires consequences.

Osteomyelitis of the jaw bones is a serious infectious and inflammatory disease that may lead to extensive bone destruction and severe local or systemic complications if not diagnosed and treated in a timely manner. Early detection of the disease is essential for preventing its progression and improving treatment outcomes. This article discusses the main clinical and theoretical aspects of the development, diagnosis, and treatment of jaw osteomyelitis. Particular attention is given to the importance of clinical examination, laboratory investigations, microbiological testing, and modern imaging methods, including computed tomography, cone-beam computed tomography, and magnetic resonance imaging. The principles of conservative and surgical treatment, elimination of the primary source of infection, antibacterial therapy, and prevention of complications are also considered. An integrated and individualized approach to diagnosis and treatment can significantly improve the prognosis and quality of life of patients with osteomyelitis of the jaw bones.

Redacted Science is a 31-year longitudinal investigation into an unclassified, progressively adaptive human physiological condition characterized by endocrine disruption, autonomic instability, metabolic rewrites, gastrointestinal collapse patterns, immune misrecognition, and suspected fungal involvement. Drawing on decades of personal clinical data, symptom logs, laboratory findings, environmental exposures, and theoretical modeling, this work proposes that a currently unrecognized co-evolutionary mechanism may underlie certain chronic, multisystem conditions traditionally dismissed or misdiagnosed.
The project integrates first-person clinical observation with systems-level analysis, exploring themes such as disrupted pituitary signaling, aberrant fluid and electrolyte handling, altered red blood cell recognition, tissue apoptosis, adaptive metabolic suppression, and long-horizon disease progression. It also examines structural gaps in modern diagnostics, highlighting where standard medical tools fail to detect atypical physiological states. Part memoir, part scientific inquiry, Redacted Science presents a detailed narrative and theoretical framework intended to stimulate discussion and re-examination within medical, metabolic, and fungal biology research communities.Science IS redacted.
