Multiple-Symbol Differential Sphere Detection Aided Differential Space-Time Block Codes Using QAM Constellations [PDF]
, 2011 We propose Multiple-Symbol Differential Detection (MSDD) aided Differential Space-Time Block Codes (DSTBCs) using QAM. Our solution eliminates the requirement of high-complexity MIMO channel estimation and its pilot overhead, while mitigating the ...

Ree groups as automorphism groups of block designs
Examples and CounterexamplesA recent classification of flag-transitive 2-designs with parameters (v,k,λ) whose replication number r is coprime to λ gives rise to eight possible infinite families of 2-designs, some of which are with new parameters.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

On automorphism groups of block designs
, 1968 This paper studies the relationship between the point orbits and block orbits for groups on automorphisms of balanced incomplete block designs. For a prime p and a group on a design with parameters v, b, r, k, λ, with t point orbits, of lengths v1, …, vt,

A Regular D‑optimal Weighing Design with Negative Correlations of Errors
Acta Universitatis Lodziensis. Folia Oeconomica, 2019 The issues concerning optimal estimation of unknown parameters in the model of chemical balance weighing designs with negative correlated errors are considered. The necessary and sufficient conditions determining the regular D‑optimal design and some new

Low energy and area efficient quaternary multiplier with carbon nanotube field effect transistors
ETRI Journal, 2021 In this study, new multiplier and adder method designs with multiplexers are proposed. The designs are based on quaternary logic and a carbon nanotube field‐effect transistor (CNTFET). The design utilizes 4 × 4 multiplier blocks.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Generalization of Wei's urn design to unequal allocations in sequential clinical trials
Contemporary Clinical Trials Communications, 2016 Wei's urn design was proposed in 1987 for subject randomization in trials comparing m≥2 treatments with equal allocation. In this manuscript, two modified versions of Wei's urn design are presented to accommodate unequal allocations.
