In this work, a proposed Multi-Fused Residual Convolutional Neural Network (MFuRe-CNN) with Auxiliary Fusing Layers (AuxFL), a Fusion Residual Block (FuRB) both with Alpha Dropouts (αDO) diagnosed various endoscopic images of gastrointestinal (GI) conditions or diseases. The proposed MFuRe-CNN handled four cases, including colons with ulcerative colitis, polyps, esophagitis, and a healthy colon, sourced from...

The study described a mentoring program of a state-funded research and its effects on research and reflective practices to graduate students. Participatory Action Research (PAR), designed as a methodical and program framework, engaged nine mentors (researchers of a state-funded research) and 29 graduate students (purposively invited) to training-based mentoring (workshops and field work), small group...

In this study, a metal–organic framework (MOF) adsorbent from recycled polyethylene terephthalate (PET) bottles was developed to effectively remove Eriochrome Black T (EBT) dye present in synthetic wastewater. A sustainable, “greener” route of MOF synthesis was adopted involving microwave-enabled depolymerization of PET to terephthalic acid (TPA) and conversion of the latter to its organic salt...

Depression is one of the most common mental health disorderswith over 264 million people suffering from it. Improvement in screening depressive disorders can lead to earlier treatment. However, some of the depression screening tools today have constraints and could be difficult to administer due to a lack of cooperation between patient and professional. It is...

This research illustrates a DC–DC buck converter with a pulse width modulation (PWM) feedback control loop and capable of power supply voltage range from VDD to 2.5× VDD, which is equivalent to 5–14 V. It is a single chip with area of 1.379 × 0.813 mm2 using 0.5 µm HV CMOS process, where high voltage (HV) MOSFETs, a Dead-time detector, a...

Agriculture is one of the most important sectors of any country, especially the Philippines. Pechay is the sixth-ranking crop for agricultural production in Batangas, according to the Philippine Statistics Authority (PSA). However, pechay is constantly threatened by different pests, such as the occurrence of cutworm (Spodoptera litura), which primarily feeds on its leaves, stalks, and...

Pest infestation is one of the serious problems of the agricultural sector in crop production and may even pose health hazards to humans. Aphis fabae, normally known as black bean aphid, is one of the main culprits that predominantly damage growing crops particularly beans, celery, and peas and may carry diseases as they multiply. Kakawate...

Mercury (Hg2+) ion is considered as one of the most lethal heavy-metal contaminants accounting for its extreme persistence, bioaccumulation, and toxicity. The objective of this study is to synthesize hybrid carbon quantum dots (h-CQDs) for the detection of Hg2+ ion in purified water and simulated seawater using ratiometric fluorescence assay between blue carbon quantum dots(b-CQDs)...

The demand for clean and safe water together with increasingly strict environmental regulations in both developed and developing countries has necessitated the need for a highly efficient yet low-cost water treatment technology to prevent the negative effects of pollutants on the human health and the environment. Nanotechnology holds great potential as a novel and promising...

Drones, or Unmanned Aerial Vehicles (UAVs), are already being utilized to help people in need worldwide. In this report, the authors designed an unmanned vehicle composed of a flight mechanism & power supply, frame, and different payloads for different missions. These also include the design of different landing gears that are mechanically replaceable depending on...
