Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality

open access: yesChemistry – A European Journal, EarlyView.
Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable

Induction and Confirmation Theory: An Approach based on a Paraconsistent Nonmonotonic Logic

open access: yesPrincípios, 2011
This paper is an effort to realize and explore the connections that exist between nonmonotonic logic and confirmation theory. We pick up one of the most wide-spread nonmonotonic formalisms – default logic – and analyze to what extent and under what ...

Complexity Results for Nonmonotonic Logics

open access: yesJournal of Logic and Computation, 1992
The paper provides complexity results for three problems of several nonmonotonic logics. Testing of existence of a fixed point and deciding whether a formula belongs to at least one fixed point are \(\Sigma^ P_ 2\)-complete. Deciding whether a formula belongs to all fixed points is \(\Pi^ P_ 2\)-complete.

A Multivariate Mixed‐Effects Regression Framework for Ground Motion Modeling: Integrating Parametric and Machine Learning Approaches

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Multivariate ground motion models (GMMs) that capture the correlation between different intensity measures (IMs) are essential for seismic risk assessment. Conventional GMMs are often developed using a two‐stage approach, where separate univariate models with predefined functional forms are fitted first, and correlation is addressed in a ...

From Empire to Aid: Analysing Persistence of Colonial Legacies in Foreign Aid to Africa

open access: yesJournal of International Development, EarlyView.
ABSTRACT For decades now, Western development agencies and donors have been castigated for their colonial biases in providing aid to Africa. It is well established that donors provide considerably more foreign aid to their former colonies relative to other countries.

Broke Autocrats, Broken Elections: Trade Shocks and Electoral Fraud in Autocracies

open access: yesEconomics &Politics, EarlyView.
ABSTRACT We argue that when terms‐of‐trade (ToT) shocks reduce resource rents, autocrats lose the fiscal capacity to sustain loyalty through patronage and increasingly rely on electoral manipulation as a survival strategy. We present a simple model in which rents finance patronage in normal times, while adverse shocks reduce the effectiveness of ...

“When life was in the home circle” in the conditional reasonings of Fregean mad-humans and logical penalists

open access: yesСлово.ру: балтийский акцент
We advocate an idea that a necessary condition for a dispute about truth amounts not to the carriers of non-ideal logical thought, but to a variety of approaches to reconstructing the logical form of conditional reasoning, which implies diversification ...

On cascade products of answer set programs

open access: yes, 2014
Describing complex objects by elementary ones is a common strategy in mathematics and science in general. In their seminal 1965 paper, Kenneth Krohn and John Rhodes showed that every finite deterministic automaton can be represented (or "emulated") by a ...

Financial Statement Information and Equity Value: The Role of Real Options Characteristics

open access: yesFinancial Management, EarlyView.
ABSTRACT This paper examines whether firm‐specific real options characteristics are equity value‐relevant beyond valuation estimates anchored in financial statements. Using extensive historical data for the United Kingdom, we assess and compare the forecast accuracy and explanatory power for stock prices of equity valuation models based on residual ...
