A new class of convolutional codes, called skew convolutional codes, that extends the class of classical fixed convolutional codes, is proposed. Skew convolutional codes can be represented as periodic time-varying convolutional codes but have a description as compact as fixed convolutional codes. Designs of generator…

Linear complementary dual codes (or codes with complementary duals) are codes whose intersections with their dual codes are trivial. We study binary linear complementary dual [n, k] codes with the largest minimum weight among all binary linear complementary dual [n, k] codes. We characterize binary linear complementary…

'Yu-Hsin Hung'] A novel dual-message QR code is proposed for carrying two individual messages that can be read by standard QR code readers: one from a close range and the other from a large distance. By exploring the module value determining the rule of typical QR code readers, we designed two-state module blocks that…

Maximum distance separable (MDS) self-dual codes have useful properties due to their optimality with respect to the Singleton bound and its self-duality. MDS self-dual codes are completely determined by the length $n,$ so the problem of constructing q-ary MDS self-dual codes with various lengths is a very interesting…

In this paper, we study self-dual codes over Z2 × (Z2 + uZ2), where u 2 = 0. Three types of self-dual codes are defined. For each type, the possible values α, β such that there exists a code C ⊆ Z α 2 ×(Z2+uZ2) β are established. We also present several approaches to construct self-dual codes over Z2 × (Z2 + uZ2).…

As far as we know, there is no decoding algorithm of any binary self-dual [40, 20, 8] code except for the syndrome decoding applied to the code directly. This syndrome decoding for a binary self-dual [40, 20, 8] code is not efficient in the sense that it cannot be done by hand due to a large syndrome table. The purpose…

In this work, extension theorems are generalized to self-dual codes over rings and as applications many new binary self-dual extremal codes are found from self-dual codes over F2m + uF2m for m = 1, 2. The duality and distance preserving Gray maps from F4 + uF4 to (F2 + uF2) 2 and F 4 2 are used to obtain self-dual…

This paper considers a scenario for multi-input multi-output (MIMO) communication systems when perfect channel state information at the transmitter (CSIT) is given while the equivalent channel state information at the receiver (CSIR) is not available. Such an assumption is valid for the downlink multi-user MIMO systems…

Experimental dissection of clonal dynamics in complex tissues requires barcoding systems that are scalable, compatible with different analytical platforms, providing phenotypic and spatial resolution. Here we introduce X-CODE, a dual-expressed RNA barcoding system designed to enable high-complexity clonal tracking…

Let F2 denote the finite field of order 2. Codes over F2 are called binary and all codes in this note are binary. The dual code C ⊥ of a code C of length n is defined as C ⊥ = {x ∈ F n 2 | x · y = 0 for all y ∈ C}, where x · y is the standard inner product. A code C is called self-dual if C = C ⊥. A self-dual code C is…

'Simon B. Eickhoff' 'Robert Langner'] Difficulties in performing two tasks at once can arise from several sources and usually increase in advanced age. Tasks with concurrent bimodal (e.g., manual and oculomotor) responding to single stimuli consistently revealed crosstalk between conflicting response codes as a…

In this article, we study the algebraic structure of double cyclic codes of length (m, n) over F 4 and we give a necessary and sufficient condition for a double cyclic code over F 4 to be reversible. Also, we determine the algebraic structure of double cyclic codes of length (m, n) over F 4 + vF 4 with v 2 = v…

Quaternion orthogonal designs (QODs) have been used to design STBCs that provide improved performance in terms of various design parameters. In this paper, we show that all QODs obtained from generic iterative construction techniques based on the Adams-Lax-Phillips approach have linear and decoupled decoders which…

Crosstalk between conflicting response codes contributes to interference in dual-tasking, an effect exacerbated in advanced age. Here, we investigated (1) brain activity correlates of such response-code conflicts, (2) activity modulations by individual dual-task performance and related cognitive abilities, (3)…

Recent studies have begun to examine bilingual cognition from more nuanced, experienced-based perspectives. The present study adds to this body of work by investigating the potential impact of code-switching on bilinguals’ inhibitory control abilities. Crucially, our bilingual participants originated from a…

Understanding how neurons encode multiple simultaneous stimuli is a fundamental question in neuroscience. We have previously introduced a novel theory of stochastic encoding patterns wherein a neuron’s spiking activity dynamically switches among its constituent single-stimulus activity patterns when presented with…

Photoswitches exhibiting large structural variation, visible light responsiveness, and multifunctionality are important for both chemistry and bionics research. However, beyond the limited variety of functional motifs, removing high-energy UV light in photoactivatable systems remains a challenge. Herein, we report a…

A dual-site extension is proposed to the previously derived ideal adsorbed solution theory analytical solution for two coadsorbing single-site BET isotherms. The proposed dual-site BET (DSBET) isotherm model is described in detail, along with multiple possible simplifications for real systems, including modeling humid…

Lineage trees of embryonic development contain much subtle information about the embryogenetic process. One type of information is contained in how the order of nodes are sorted at each level of the tree. Sorting of lineage trees is accomplished using a specific criterion for all levels (each representing a division…

Bayesian optimization (BO) has become increasingly important for experimental optimization across scientific domains, yet implementing BO pipelines requires significant programming expertise and familiarity with specialized frameworks. This creates a barrier for domain experts who could benefit from BO but lack the…
