Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

We developed computational de novo protein design methods capable of tackling several important areas of protein design. To disseminate these methods we present Protein WISDOM, an online tool for protein design (http://www.proteinwisdom.org). Starting from a structural template, design of monomeric proteins for increased stability and complexes for increased binding affinity can be performed.

There is a need to develop alternative prosthesis attachment due to limb loss attributed to vascular occlusive diseases and trauma. The goal of the work is to introduce an osseointegrated intelligent implant design system to increase skeletal fixation and reduce periprosthetic infection rates for patients needing osseointegrated technology.
FAQs
Physical energy models help estimate which amino acid arrangements are compatible with a desired protein structure. By assigning relative energetic favorability to candidate sequences or mutations, they support predictions about folding and stability. This gives the design process a quantitative basis for ranking alternatives, rather than relying only on sequence inspection or choosing variants without a structural rationale.
Sequence analysis contributes information about candidate amino acid sequences, while optimization algorithms search through possible sequence changes. Their combination helps connect particular sequence choices with predicted effects on folding, stability, binding, or catalytic activity. This is important because design decisions depend not only on a target structure or function, but also on comparing many possible sequence alternatives.
Structural biology supplies the structural perspective needed to judge whether a proposed amino acid sequence is consistent with a specified protein structure. In the design workflow, that perspective complements energy calculations and sequence analysis. It helps researchers focus computational searches on candidates whose predicted folding or stability is relevant to the structure or function being pursued.
Researchers first specify the protein structure or function they want to achieve, then use structural information, energy models, sequence analysis, and optimization algorithms to generate or modify candidate sequences. The resulting designs are evaluated and ranked according to predicted properties such as stability, binding, or catalytic activity. Selected candidates must then undergo laboratory testing.
The approach is useful when researchers need protein variants with particular structural or functional properties. Its applications include developing engineered enzymes, therapeutic proteins, biosensors, and other molecular tools. By prioritizing candidates computationally before laboratory work, it can reduce the number of experimental designs required and make protein engineering more efficient.
Laboratory validation determines whether predicted sequence changes produce the intended effects on folding, stability, binding, or catalytic activity. Comparing results with computational rankings can reveal useful sequence-function relationships, even when a design does not perform as expected. This experimental step remains essential because computational predictions guide candidate selection but do not replace biological testing.
