To investigate the role of pollen-specific RALFs in another plant species, we combined gene expression data with phylogenetic and biochemical studies to identify candidate orthologs in maize (Zea mays). We show that Clade IB ZmRALF2/3 mutations, but not Clade III ZmRALF1/5 mutations, cause cell wall instability in the sub-apical region of the growing pollen tube. ZmRALF2/3 are mainly located in the cell wall and are partially able to complement the pollen germination defect of their Arabidopsis orthologs AtRALF4/19. Mutations in ZmRALF2/3 compromise pectin distribution patterns leading to altered cell wall organization and thickness culminating in pollen tube burst. Clade IB, but not Clade III ZmRALFs, strongly interact as ligands with the pollen-specific Catharanthus roseus RLK1-like (CrRLK1L) receptor kinases Zea mays FERONIA-like (ZmFERL) 4/7/9, LORELEI-like glycosylphosphatidylinositol-anchor (LLG) proteins Zea mays LLG 1 and 2 (ZmLLG1/2) and Zea mays pollen extension-like (PEX) cell wall proteins ZmPEX2/4. Notably, ZmFERL4 outcompetes ZmLLG2 and ZmPEX2 outcompetes ZmFERL4 for ZmRALF2 binding. Based on these data, we suggest that Clade IB RALFs act in a dual role as cell wall components and extracellular sensors to regulate cell wall integrity and thickness during pollen tube growth in maize and probably other plants.","lang":"eng"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1532-298X"],"issn":["1040-4651"]},"publication_status":"epub_ahead","status":"public","keyword":["Cell Biology","Plant Science"],"type":"journal_article","article_type":"original","tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png"},"_id":"14726","extern":"1","ddc":["580"],"date_updated":"2024-01-03T12:43:41Z","quality_controlled":"1","publisher":"Oxford University Press","oa":1,"doi":"10.1093/plcell/koad324","date_published":"2023-12-23T00:00:00Z","date_created":"2024-01-02T11:19:37Z","day":"23","publication":"The Plant Cell","has_accepted_license":"1","year":"2023","article_number":"koad324","title":"The RALF signaling pathway regulates cell wall integrity during pollen tube growth in maize","author":[{"first_name":"Liang-Zi","last_name":"Zhou","full_name":"Zhou, Liang-Zi"},{"first_name":"Lele","last_name":"Wang","full_name":"Wang, Lele"},{"last_name":"Chen","full_name":"Chen, Xia","first_name":"Xia"},{"id":"f43371a3-09ff-11eb-8013-bd0c6a2f6de8","first_name":"Zengxiang","full_name":"Ge, Zengxiang","orcid":"0000-0001-9381-3577","last_name":"Ge"},{"first_name":"Julia","full_name":"Mergner, Julia","last_name":"Mergner"},{"last_name":"Li","full_name":"Li, Xingli","first_name":"Xingli"},{"first_name":"Bernhard","last_name":"Küster","full_name":"Küster, Bernhard"},{"first_name":"Gernot","last_name":"Längst","full_name":"Längst, Gernot"},{"full_name":"Qu, Li-Jia","last_name":"Qu","first_name":"Li-Jia"},{"last_name":"Dresselhaus","full_name":"Dresselhaus, Thomas","first_name":"Thomas"}],"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Zhou, Liang-Zi, Lele Wang, Xia Chen, Zengxiang Ge, Julia Mergner, Xingli Li, Bernhard Küster, Gernot Längst, Li-Jia Qu, and Thomas Dresselhaus. “The RALF Signaling Pathway Regulates Cell Wall Integrity during Pollen Tube Growth in Maize.” The Plant Cell.

Any algorithm that fixes happy leaves—as all known approximation algorithms for the problem do—has approximation factor at least 4/3. Furthermore, the two best-known 2-approximation algorithms have approximation factor exactly 2. 3. A generalized problem—weighted coloured token swapping—is NP-complete on trees, but solvable in polynomial time on paths and stars.

In the forefront of the current solution is the idea of separating the execution of the updates encoded in a block from the ordering of blocks. In order to achieve this, a new class of protocols called rollups has emerged. Rollups have as input a total ordering of valid and invalid transactions and as output a new valid state-transition.\r\nIf we study rollups from a distributed computing perspective, we uncover that rollups take as input the output of a Byzantine Atomic Broadcast (BAB) protocol and convert it to a State Machine Replication (SMR) protocol. BAB and SMR, however, are considered equivalent as far as distributed computing is concerned and a solution to one can easily be retrofitted to solve the other simply by adding/removing an execution step before the validation of the input.\r\nThis “easy” step of retrofitting an atomic broadcast solution to implement an SMR has, however, been overlooked in practice. In this paper, we formalize the problem and show that after BAB is solved, traditional impossibility results for consensus no longer apply towards an SMR. Leveraging this we propose a distributed execution protocol that allows reduced execution and storage cost per executor (O(log2n/n)) without relaxing the network assumptions of the underlying BAB protocol and providing censorship-resistance. Finally, we propose efficient non-interactive light client constructions that leverage our efficient execution protocols and do not require any synchrony assumptions or expensive ZK-proofs."}],"oa_version":"Preprint","volume":13950,"publication_status":"published","publication_identifier":{"issn":["1611-3349"],"isbn":["9783031477539"],"eissn":["0302-9743"],"eisbn":["9783031477546"]},"language":[{"iso":"eng"}]},{"abstract":[{"text":"Redox flow batteries (RFBs) rely on the development of cheap, highly soluble, and high-energy-density electrolytes.

Here, an investigation of nitrogen-rich fused heteroaromatic quinones was carried out to explore avenues for electrolyte development. These quinones were synthesized and screened by using electrochemical techniques. The most promising candidate, 4,8-dioxo-4,8-dihydrobenzo[1,2-d:4,5-d′]bis([1,2,3]triazole)-1,5-diide (−0.68 V(SHE)), was tested in both an asymmetric and symmetric full-cell setup resulting in capacity fade rates of 0.35% per cycle and 0.0124% per cycle, respectively. In situ ultraviolet-visible spectroscopy (UV–Vis), nuclear magnetic resonance (NMR), and electron paramagnetic resonance (EPR) spectroscopies were used to investigate the electrochemical stability of the charged species during operation. UV–Vis spectroscopy, supported by density functional theory (DFT) modeling, reaffirmed that the two-step charging mechanism observed during battery operation consisted of two, single-electron transfers. The radical concentration during battery operation and the degree of delocalization of the unpaired electron were quantified with NMR and EPR spectroscopy.","lang":"eng"}],"oa_version":"Published Version","main_file_link":[{"url":"https://doi.org/10.1021/acsaem.3c02223","open_access":"1"}],"month":"12","publication_status":"epub_ahead","publication_identifier":{"eissn":["2574-0962"]},"language":[{"iso":"eng"}],"ec_funded":1,"_id":"14733","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","keyword":["Electrical and Electronic Engineering","Materials Chemistry","Electrochemistry","Energy Engineering and Power Technology","Chemical Engineering (miscellaneous)"],"status":"public","date_updated":"2024-01-08T09:03:01Z","ddc":["540"],"department":[{"_id":"StFr"}],"oa":1,"quality_controlled":"1","publisher":"American Chemical Society","year":"2023","has_accepted_license":"1","publication":"ACS Applied Energy Materials","day":"28","date_created":"2024-01-05T09:20:48Z","doi":"10.1021/acsaem.3c02223","date_published":"2023-12-28T00:00:00Z","project":[{"call_identifier":"H2020","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413"}],"citation":{"ista":"Jethwa RB, Hey D, Kerber RN, Bond AD, Wright DS, Grey CP. 2023.

Cu3SbSe4 is a promising p-type TE material based on relatively earth abundant elements. However, the challenge lies in its poor electrical conductivity. Herein, an efficient and scalable solution-based approach is developed to synthesize high-quality Cu3SbSe4 nanocrystals doped with Pb at the Sb site. After ligand displacement and annealing treatments, the dried powders are consolidated into dense pellets, and their TE properties are investigated. Pb doping effectively increases the charge carrier concentration, resulting in a significant increase in electrical conductivity, while the Seebeck coefficients remain consistently high. The calculated band structure shows that Pb doping induces band convergence, thereby increasing the effective mass. Furthermore, the large ionic radius of Pb2+ results in the generation of additional point and plane defects and interphases, dramatically enhancing phonon scattering, which significantly decreases the lattice thermal conductivity at high temperatures. Overall, a maximum figure of merit (zTmax) ≈ 0.85 at 653 K is obtained in Cu3Sb0.97Pb0.03Se4. This represents a 1.6-fold increase compared to the undoped sample and exceeds most doped Cu3SbSe4-based materials produced by solid-state, demonstrating advantages of versatility and cost-effectiveness using a solution-based technology.","lang":"eng"}],"acknowledgement":"Y.L. acknowledges funding from the National Natural Science Foundation of China (NSFC) (Grants No. 22209034), the Innovation and Entrepreneurship Project of Overseas Returnees in Anhui Province (Grant No. 2022LCX002).
