This paper considers the security aspect of the robust zero-bit watermarking technique ‘Broken Arrows’(BA), which was invented and tested for the international challenge BOWS-2. The results of the first episode of the challenge showed that BA is very robust. Last year, we proposed an enhancement so-called AWC, which further strengthens the robustness against the worst attack disclosed during th...

Left/right asymmetric features of animals are either randomly distributed on either the left or right side within a population ("antisymmetries") or found stereotypically on one particular side of an animal ("directional asymmetries"). Both types of asymmetries can be found in nervous systems, but whether the regulatory programs that establish these asymmetries share any mechanistic features is...

Information about nutrient availability is assessed via largely unknown mechanisms to drive developmental decisions, including the choice of Caenorhabditis elegans larvae to enter into the reproductive cycle or the dauer stage. In this study, we show that CMK-1 CaMKI regulates the dauer decision as a function of feeding state. CMK-1 acts cell-autonomously in the ASI, and non cell-autonomously i...

Distributed constraint satisfaction problems (DisCSPs) are composed of agents, each holding its own variables, that are connected by constraints to variables of other agents. Due to the distributed nature of the problem, message delay can have unexpected effects on the behavior of distributed search algorithms on DisCSPs. This has been shown in experimental studies of asynchronous backtracking ...

The diversity of sensory cilia on Caenorhabditis elegans neurons allows the animal to detect a variety of sensory stimuli. Sensory cilia are assembled by intraflagellar transport (IFT) kinesins, which transport ciliary precursors, bound to IFT particles, along the ciliary axoneme for incorporation into ciliary structures. Using fluorescence microscopy of living animals and serial section electr...

The deterioration of soil physical properties had led to a decrease in soil–water availability facility agriculture. Thus, an experiment was set up with five treatments 0% (CK, No additives), 3% biochar (BA3, Mass ratio), earthworm manure (QA3), 5% (BA5), and (QA5) investigate the effects on hydraulic characteristics under greenhouse conditions. including bulk density (BD) total porosity (TP) w...

To ensure safe passage blind travellers utilize mobility aids such as the white cane to preview space their body will move through. Augmented canes (AWC) have increased this range reduce collisions, but consequently incurred lower walking speeds. The literature has blamed slowdown on AWC provided alerts that are additional feedback, unnecessary, too complex, and anticipatory of users. Two withi...

Animals track fluctuating stimuli over multiple timescales during natural olfactory behaviors. Here, we define mechanisms underlying these computations in Caenorhabditis elegans. By characterizing neuronal calcium responses to rapidly fluctuating odor sequences, we show that sensory neurons reliably track stimulus fluctuations relevant to behavior. AWC olfactory neurons respond to multiple odor...

We present resolvent-based learning as a new nogood learning method for a distributed constraint satisfaction algorithm. This method is based on a look-back technique in constraint satisfaction algorithms and can efficiently make effective nogoods. We combine the method with the asynchronous weakcommitment search algorithm (AWC) and evaluate the performance of the resultant algorithm on distrib...
