L-Fuzzy Relations in Coq
… for reasoning and program execution using Coq, an interactive theorem prover based on Higher-Order Logic (HOL) with dependent types. This implementation can be used to specify and develop correct software based on L-fuzzy relations such as fuzzy controllers. We give an overview of lattices, …

Approximation Algorithms using Allegories and Coq
… language and interactive theorem prover Coq is used for the implementation purposes. This language is based on Higher-Order Logic (HOL) with dependent types which support both reasoning and program execution. In addition to the abstract theory, we provide the model of set-theoretic …

Correct-by-construction finite field arithmetic in Coq
… I describe the methodologies used to create a Coq framework that generates implementations of finite-field arithmetic routines along with proofs of their correctness, given nothing but the modulus.

Crafting certified elliptic curve cryptography implementations in Coq
… relies heavily on a proof assistant such as Coq and most techniques are explained through code snippets, every Coq feature is introduced and motivated when it is first used to accommodate a non-Coq-savvy reader.

Formally Verified Code Obfuscation in the Coq Proof Assistant
… specification and verification, by using the Coq Proof Assistant and IMP (a simple imperative language within it), to formulate what it means for a program's semantics to be preserved by an obfuscating transformation, and give formal machine-checked proofs that these properties hold. We …

Formal Verification of Relational Algebra Transformations in Fiat2 Using Coq
… that integrates formal verification via the Coq proof assistant. We focus on proving the correctness of several rewrite-based query optimizations commonly used in database engines. Specifically, we formalize and prove the correctness of algebraic rewrites involving combinations of filters, …

CoqIOA : a formalization of IO automata in the Coq proof assistant
… reuse of code and proofs. This thesis presents CoqIOA, a framework for reasoning about distributed systems in a compositional way. CoqIOA builds on the theory of input/output automata to support specification, proof, and composition of systems within the proof assistant. The framework's …

Extracting and optimizing low-level bytecode from high-level verified Coq
… the Gallina functional language used in the Coq proof assistant. MCQC translates pure and recursive functions into C++17, while compiling monadic effectful functions to imperative C++ system calls. With a series of memory and performance optimizations, MCQC combines verifiability with memory …

Biology of immature Culicoides variipennis ssp. australis (Coq.) (Diptera:Ceratopogonidae) at Saltville, VA
The larval and pupal biology of a unique population of gulicoides variipennis inhabiting the brine ponds of Saltville, VA was studied. Developmental threshold temperatures (OC) and thermal constants (Odays) for larvae and pupae were 9.6OC and 387Odays (larval stage) and 9.6OC and 3OOdays (pupal …

Reducing the cost of quality (COQ) through increased product reliability and reduced process variability
… is referred to as Dell's Cost Of Quality (COQ). A large percentage of Dell's COQ is spent by warranty-support and customer service organizations (Services). While the costs of defects most directly affects Dell through the expenditures in such Service organizations, the causes of are found …

On the Oxidative Half-Reaction of Plasmodium Falciparum Dihydroorotate Dehydogenase
… The lipophilic co-substrate ubiquinone (CoQ) is shown to partition into detergent micelles in a hydrophobic chain length-dependent manner. Additionally, the enzyme is shown to associate with liposomes, which is likely mediated by its hydrophobic N-terminal domain. This arrangement …

Structure-based theoretical characterisation of the redox-dependent titration behaviour of cytochrome bc1
… energy of electron transfer from coenzyme Q (CoQ) to cytochrome c to shift protons across the membrane. The chemical energy of reduced CoQ is thus converted into the energy of a proton motive force. The coupling between electron transfer and proton translocation is based on the Q-cycle …

The Effect of PDSS2, a Component of the Coenzyme Q Biosynthetic Pathway, on Murine Oocyte Embryo Development
… is the reduced availability of coenzyme Q (coQ), a component of the mitochondrial respiratory chain, as it has been previously shown that both transcript and protein expression of various coQ biosynthetic enzymes decrease in aged murine oocytes. To further explore the impact of coQ …

Evaluación preliminar de insecticidas químicos, botánicos y biológicos en el control de la mosquita del sorgo (Contarinia sorguicola Coq) y los rendimientos de granos en la variedad pinolero - 1
… de la mosquita del sorgo (Contarinia sorghicola Coq). Se realizó un experimento en el periodo comprendido entre los meses de septiembre a diciembre de 1996, en el Centro Nacional de Investigación Agropecuaria (CNIA/INTA), cuyos suelos pertenecen a la serie Sabana Grande con drenaje moderadamente …

Elucidating the mechanism of mitochondrial superoxide production in pro-inflammatory macrophages
… (AOX) to determine the influence of an oxidised CoQ pool on mitochondrial superoxide production. Using this approach, I demonstrated that LPS induced mitochondrial superoxide production is driven by an elevated proton motive force (∆p), measured as mitochondrial membrane potential (∆ψm), and a …

Investigating complex I dynamics and ROS production in ischaemia-reperfusion injury
… (∆p) in conjunction with a reduced coenzyme Q (CoQ) pool, with the required electrons deriving from succinate oxidation. ROS causes severe damage to cellular components, leading to cell death and ultimately to chronic inflammation. In order to expand our knowledge on the role and function of …
