Advanced Experiment Design Strategies for Drug Development

open access: yesAdvanced Intelligent Discovery, EarlyView.
Wang et al. analyze 592 drug development studies published between 2020 and 2024 that applied design of experiments methodologies. The review surveys both classical and emerging approaches—including Bayesian optimization and active learning—and identifies a critical gap between advanced experimental strategies and their practical adoption in ...

State Complexity of Testing Divisibility [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
Under some mild assumptions, we study the state complexity of the trim minimal automaton accepting the greedy representations of the multiples of m >= 2 for a wide class of linear numeration systems.

Operational Characterization of Divisibility of Dynamical Maps

open access: yes, 2016
Divisibility of dynamical maps turns out to be a fundamental notion in characterising Markovianity of quantum evolution, although the decision problem for divisibility itself is computationally intractable.

Tendon‐Driven Compliant Wheel‐Less Snake Robot for Undulatory Locomotion Using Conformable Ground Contacts

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a tendon‐driven compliant snake robot that uses globally applied vertical bending and axial twisting along its body to enable various gaits. Body deflection from compliance and weight passively generates the ground contact patterns required for locomotion.

Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

On an Arithmetic Inequality

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014
We obtain an arithmetic proof and a refinement of the inequality ϕ (nk) + σk(n) < 2nk, where n ≧ 2 and k ≧ 2. An application to another inequality is also provided.

On a divisibility problem [PDF]

open access: yesMathematica Bohemica, 2019
Let $p_1, p_2, \cdots$ be the sequence of all primes in ascending order. Using explicit estimates from the prime number theory, we show that if $ k \geq5 $, then (p_{k+1}-1)! \mid(\tfrac12 (p_{k +1} - 1))! p_ k!, which improves a previous result of

Characteristic Varieties of Hypersurface Complements [PDF]

open access: yes, 2016
We give divisibility results for the (global) characteristic varieties of hypersurface complements expressed in terms of the local characteristic varieties at points along one of the irreducible components of the hypersurface.

Enhancing Plateau Capacity of Binder‐Free and Self‐Supported Napkin‐Based Hard Carbon Anodes for Sodium‐Ion Batteries Via a Pre‐Oxidation Modulation Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Precise regulation of preoxidation time and carbonization temperature in biomass napkin‐derived hard carbon generates abundant closed pores and ultramicropores, significantly enhancing the capacity in the low‐potential plateau region (the high plateau capacity of 266 mAh g−1) and thereby achieving highly reversible sodium‐ion storage (395 mAh g−1 at 30
