Universal construction of W_{p,q} algebras
, 1998 We present a direct construction of abstract generators for q-deformed W_N algebras. This procedure hinges upon a twisted trace formula for the elliptic algebra A_{q,p}(sl(N)_c) generalizing the previously known formulae for quantum groups.Comment ...

Hinges for origami-inspired structures by multimaterial additive manufacturing
Materials & Design, 2020 Recent studies demonstrate novel metamaterials featuring unique properties by combining origami-inspired designs with additive manufacturing. In particular, the use of flexural hinges endows distinct advantages towards miniaturization and fabrication ...

Structural behaviour of masonry arch with no-horizontal springing settlement [PDF]
, 2017 This paper presents a calculation procedure for assessing the structural integrity of a masonry arch with non-horizontal springing settlement. By applying the Principle of Virtual Work (PVW) to the deformed arch system, the procedure proposed herein ...

Self‐Folding Method Using a Linkage Mechanism for Origami Structures
Advanced Intelligent Systems, 2023 Origami is garnering attention in fields such as medical and electronic devices as this approach allows transitioning from a 2D to a 3D structure. Self‐folding method is effective for fabricating origami structures, but conventional strategy of self ...

Universal hinges and the bounds of sense [PDF]
, 2019 According to Danièle Moyal-Sharrock, Wittgenstein’s On Certainty presents a theory of hinges, and hinges have a role to play in a foundationalist epistemology (2013).

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Role of a "Local" Cosmological Constant in Euclidean Quantum Gravity [PDF]
, 1996 In 4D non-perturbative Regge calculus a positive value of the effective cosmological constant characterizes the collapsed phase of the system. If a local term of the form $S'=\sum_{h \epsilon \{h_1,h_2,...\} } \lambda_h V_h$ is added to the gravitational

Intein‐based modular chimeric antigen receptor platform for specific CD19/CD20 co‐targeting
Molecular Oncology, EarlyView.CARtein is a modular CAR platform that uses split inteins to splice antigen‐recognition modules onto a universal signaling backbone, enabling precise, scarless assembly without re‐engineering signaling domains. Deployed here against CD19 and CD20 in B‐cell malignancies, the design supports flexible multi‐antigen targeting to boost T‐cell activation and

Seismic Damage Detection of Moment Resisting Frame Structures Using Time-Frequency Features
Shock and Vibration, 2018 To detect seismic damage of moment resisting frame (MRF) structures, a data-driven method using the fractal dimension (FD) of time-frequency feature (TFF) of structural seismic dynamic responses at measured stories is extended and refined.
