Oxygenic photosynthesis is Earth's dominant metabolism, having evolved to harvest the largest expected energy source at the surface of most terrestrial habitable zone planets. Using CO2 and H2O-molecules that are expected to be abundant and widespread on habitable terrestrial planets-oxygenic photosynthesis is plausible as a significant planetary process with a global impact. Photosynthetic O2 ...

In the classical approach to digital topology (see e.g. [12] and [13]), graph theoretic tools are used for structuring Z, namely the well-known binary relations of 4-adjacency and 8-adjacency. But neither 4adjacency nor 8-adjacency itself allows an analogue of the Jordan curve theorem (cf. [9]) and, therefore, one has to use a combination of the two adjacencies. To overcome this disadvantage, a...

Anomaly detection in multivariate time series is an important research direction, which helps to improve the security of industrial systems by detecting abnormally unreliable devices. Multivariate (MTS) anomalies not only need pay attention correlation between different but also consider abnormal changes relationship variables. Once influence two variables that each other ignored, it will likel...

Three serological tests for candidiasis, agar gel diffusion (AGD-1), whole cell agglutination (AGGL-1), and latex agglutination (LAT), were evaluated by six laboratories with 100 coded sera. In addition, each of six laboratories performed a test of its choice, either the AGD-2, the AGD-3, the AGGL-2, or one of three counterimmunoelectrophoresis (CEP) methods (CEP-1, CEP-2, and CEP-3). Results a...

MOTIVATION Transcription factor binding sites (TFBSs) are typically short in length, thus search with a profile model from known TFBSs produces many false positives. When combined with additional information, gene expression data in this article, sensitivity and specificity of TFBS search can be improved significantly. RESULTS By modifying our previous REFINEMENT approach, we developed dPatte...

We introduce a method for analyzing small interfering RNA (siRNA) genetic screens based entirely on off-target effects. Using a screen for members of the Wnt pathway, we demonstrate that this method identifies known pathway components, some of which are not present in the screening library. This technique can be applied to siRNA screen results retroactively to confirm positives and identify gen...

Geometric Hashing is a well-known technique for object recognition. This paper proposes a novel method aimed at improving the performance of Geometric Hashing in terms of robustness toward occlusion and clutter. To this purpose, it employs feature descriptors to notably decrease the amount of false positives that generally arise under these conditions. An additional advantage of the proposed te...

Ding et al [DNRS97] propose a stream generator based on several layers. We present several attacks. First, we observe that the non-surjectivity of a linear combination step allows us to recover half the key with minimal effort. Next, we show that the various bytes are insufficiently mixed by these layers, enabling an attack similar to those on two-loop Vigenere ciphers to recover the remainder ...

Positive Health, Dignity, and Prevention (PHDP) is a term for HIV prevention interventions with people living with HIV (PLHIV). PHDP has also been called positive prevention, prevention with positives, prevention by positives, and prevention for positives. In general, PHDP activities focus on achieving four main goals: (1) keeping PLHIV physically healthy; (2) keeping PLHIV mentally and psychol...
