On Maximum Entropy Density Estimation with Relaxed Moment Constraints [PDF]

open access: yesEntropy
We study Maximum Entropy density estimation on continuous domains under finitely many moment constraints, formulated as the minimization of the Kullback–Leibler divergence with respect to a reference measure.

Heteronomy of architecture. Between hybridation and contamination of knowledge

open access: yesTechne, 2021
«For a place to leave an impression on us, it must be made of time as well as space – of its past, its history, its culture» (Sciascia, 1987). Architecture is one the many disciplines which, due to their heteronomous nature, aspire to represent the ...

T-duality invariant approaches to string theory [PDF]

open access: yes, 2010
PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.

Fermionic T-duality and U-duality in type II supergravity [PDF]

open access: yes, 2011
PhDThis thesis deals with the two duality symmetries of N = 2 D = 10 supergravity theories that are descendant from the full superstring theory: fermionic T-duality and U-duality.

Multiderivative methods for nonlinear second order boundary value problems [PDF]

open access: yes, 1985
Second, fourth and sixth order methods are developed and analysed for the numerical solution of non-linear second order boundary value problems. The methods arise from a two-step recurrence relation involving exponential terms, these being replaced by ...

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
