Abstract Iron and phosphorus are essential nutrients that exist at low concentrations in surface waters may be co-limiting resources for phytoplankton growth. Here, we show deficiency increases the growth of iron-limited cyanobacteria ( Synechocystis sp. PCC 6803) through a PhoB-mediated regulatory network. We find PhoB, addition to its well-recognized role controlling phosphate homeostasis, also regulates key metabolic processes crucial cyanobacteria, including ROS detoxification iron...

As the fourth passive circuit component, a memristor is nonlinear resistor that can "remember" amount of charge passing through it. The characteristic "remembering" and non-volatility makes memristors great potential candidates in many fields. Nowadays, only few groups have ability to fabricate memristors, most researchers study them by theoretic analysis simulation. In this paper, we first analyse theoretical base characteristics then use simulation program with integrated emphasis as our...

Abstract Orange carotenoid protein (OCP) is a photoactive that participates in the photoprotection of cyanobacteria. There are 2 full-length OCP proteins, 4 N-terminal paralogs (helical [HCP]), and 1 C-terminal domain-like (CCP) found Nostoc flagelliforme, desert cyanobacterium. All HCPs (HCP1 to 3 HCP6) from N. flagelliforme demonstrated their excellent singlet oxygen quenching activities, which HCP2 was strongest quencher compared with others. Two OCPs, OCPx1 OCPx2, were not involved...

Multi-spectral Light Detection and Ranging (LiDAR) is an active sensor that can simultaneously obtain spatial geometric data multi-wavelength information, offering multi-attribute features for geoinformation products such as point cloud scene recognition. Despite these advantages, semantic segmentation of fine-grained scenes in multi-spectral LiDAR remains a challenging task, mainly due to the disordered arrangement large amount involved. In particular, it crucial extract high-quality from...

Gait-based person re-identification (Re-ID) is valuable for safety-critical applications, and using only 3D skeleton data to extract discriminative gait features Re-ID an emerging open topic. Existing methods either adopt hand-crafted or learn by traditional supervised learning paradigms. Unlike previous methods, we the first time propose a generic encoding approach that can utilize unlabeled representations in self-supervised manner. Specifically, introduce self-supervision reconstruct...

Unipolar memristive devices are an important kind of resistive switching devices. However, few circuit models them have been proposed. In this paper, we propose the SPICE modeling flux-controlled unipolar based on memristance versus state map.

Gravitational wave (GW) birefringence is a remarkable phenomenon that can be used to test the parity violation in gravity. By coupling fuzzy dark matter (FDM) scalar gravitational Chern-Simons term, we explore GW effects FDM background.
