- P&T修復における汚染物質除去の予測における5つの代理モデル(Kriging、Polynomial Interpolation、SVR、RF、DNN)のパフォーマンスを比較すること。
- P&T最適化を強化するために複数の代理モデルを組み合わせる可能性を探求すること。
- 地下水修復のためのマルチサロゲート最適化フレームワークを開発および評価すること。
主な方法:
- 5つの代理モデル(Kriging、Polynomial Interpolation、Support Vector Regression(SVR)、Random Forest(RF)、Deep Neural Network(DNN))を評価しました。
- 多様なP&Tスキーム全体での汚染物質除去効率に対するモデルの予測精度を評価しました。
- 遺伝的アルゴリズムと5つのモデルすべてを統合したマルチサロゲート最適化フレームワークを開発しました。
主要な成果:
- ディープニューラルネットワーク(DNN)は全体的に最も高い予測精度を示しましたが、単一のモデルがすべてのケースで一貫して優れているわけではありませんでした。
- 複数の代理モデルを組み合わせたフレームワークは、補完的な強みを活用しました。
- 最適化された修復スキームは、最適化されていないスキーム(残差19.2-21.7%)と比較して、優れた汚染物質除去(残差17.5%)を達成しました。
結論:
- 複数の代理モデルを組み合わせることで、ポンプ・アンド・トリート修復スキームの最適化に大きな利点が得られます。
- 開発されたマルチサロゲートフレームワークは、環境管理のための堅牢なツールを提供します。

Bioavailability Study Design: Single Versus Multiple Dose Studies
250
Bioavailability studies are essential for understanding how a drug is absorbed, distributed, metabolized, and excreted in the body. These studies assess the extent and rate at which the active pharmaceutical agent becomes available at the site of action. The design of bioavailability studies can involve single-dose or multiple-dose regimens, each with distinct advantages and limitations.Single-dose studies are the preferred approach due to their simplicity and reduced drug exposure for...

ATP Driven Pumps III: V-type Pumps
4.9K
V-type pumps are ATP-driven pumps found in the vacuolar membranes of plants, yeast, endosomal and lysosomal membranes of animal cells, plasma membranes of a few specialized eukaryotic cells, and some prokaryotes. They are also known as the V1Vo-ATPase, that couple ATP hydrolysis to transport protons against a concentration gradient.
The peripheral or cytosolic V1 domain with eight subunits is involved in ATP hydrolysis. The integral or transmembrane V0 domain containing at least five subunits...

ATP Driven Pumps II: P-type Pumps
6.4K
The P-type pumps are a large family of integral membrane transporter ATPases. They are divided into five major types based on substrate specificity, from I to V.
A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...

Pumped Concrete
395
Concrete in large quantities can be pumped across long distances for placing in inaccessible sites. This system comprises a hopper that receives concrete from a mixer, a pump to propel the concrete, and pipelines that facilitate its delivery.
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...

Group Design
10.7K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...
