A Review on Soft Error Correcting Techniques of Aerospace-Grade Static RAM-Based Field-Programmable Gate Arrays.

Aerospace-grade SRAM-based field-programmable gate arrays (FPGAs) used in space applications are highly susceptible to single event effects, leading to soft errors in FPGAs. Additionally, as FPGAs scale up, the difficulty of correcting soft errors also increases. This paper proposes that performing soft error sensitivity analysis on FPGAs can help target the more sensitive areas for detection and correction, thereby improving the efficiency of soft error repair.

Evasion strategies of porcine reproductive and respiratory syndrome virus.

During the co-evolution of viruses and their hosts, viruses have developed various strategies for overcoming host immunological defenses so that they can proliferate efficiently. Porcine reproductive and respiratory syndrome virus (PRRSV), a significant virus to the swine industry across the world, typically establishes prolonged infection diverse and complicated mechanisms, which is one of the biggest obstacles for controlling the associated disease, porcine reproductive and respiratory syndrome (PRRS). In this review, we summarize the latest research on how PRRSV circumvents host antiviral responses from both the innate and adaptive immune systems and how this virus utilizes other evasion mechanisms, such as the manipulation of host apoptosis and microRNA.

Genesis of Superlow Friction in Strengthening Si-DLC/PLC Nanostructured Multilayer Films for Robust Superlubricity at Ultrahigh Contact Stress.

Diamond-like carbon (DLC) films have significant potential to provide solutions for the friction reduction and the lubricity problem of mechanical moving friction pairs. However, the realization of excellent lubrication or even superlubricity and long lifetime under heavy loading conditions is still a great challenge, which is crucial for the applications of DLC in harsh environments. Here, we construct a group of property-strengthening Si-DLC/PLC multilayer films that could withstand ultrahigh contact stresses and achieve robust superlubricity.

Vesicular stomatitis virus glycoprotein suppresses nuclear factor kappa-B- and mitogen-activated protein kinase-mediated pro-inflammatory responses dependent on sialic acids.

Vesicular stomatitis (VS), characterized by vesicular lesions, produces significant economic losses in livestock industry. Infection by its causative agent, VS virus (VSV), has been previously shown to be mediated by the glycoprotein (G) during attachment, endocytosis and membrane fusion. In the current study, we revealed a novel role of VSV G protein in negative regulation of host cell pro-inflammatory responses.

IFI16 Inhibits Porcine Reproductive and Respiratory Syndrome Virus 2 Replication in a MAVS-Dependent Manner in MARC-145 Cells.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a single-stranded positive-sense RNA virus, and the current strategies for controlling PRRSV are limited. Interferon gamma-inducible protein 16 (IFI16) has been reported to have a broader role in the regulation of the type I interferons (IFNs) response to RNA and DNA viruses. However, the function of IFI16 in PRRSV infection is unclear.

Porcine reproductive and respiratory syndrome virus induces interleukin-1β through MyD88/ERK/AP-1 and NLRP3 inflammasome in microglia.

Porcine reproductive and respiratory syndrome virus (PRRSV) infection which caused severe reproductive failure and respiratory disorders in swine is accompanied with severe nervous symptoms. Our previous studies demonstrated that microglia, the resident innate immune cells in central nervous system (CNS), could support PRRSV infection and replication in vitro. And PRRSV infection led to the increased expressions of large amounts of proinflammatory cytokines and chemokines which contributed to neuropathogenesis of PRRSV.

Characterization of the interaction between recombinant porcine aminopeptidase N and spike glycoprotein of porcine epidemic diarrhea virus.

Porcine epidemic diarrhea (PED) has caused huge economic losses to the global pork industry. Infection by its causative agent PED virus (PEDV), an Alpha-coronavirus, was previously proven to be mediated by its spike (S) glycoprotein and a cellular receptor porcine aminopeptidase N (pAPN). Interestingly, some recent studies have indicated that pAPN is not a functional receptor for PEDV.

High-resolution transcript profiling reveals shoot abscission process of spruce dwarf mistletoe Arceuthobium sichuanense in response to ethephon.

Arceuthobium (dwarf mistletoes) are hemiparasites that may cause great damage to infected trees belonging to Pinaceae and Cupressaceae. Currently, dwarf mistletoe control involves the use of the ethylene-producing product ethephon (ETH), which acts by inducing dwarf mistletoe shoot abscission. However, the process by which ETH functions is mostly unknown.

Molecular epidemiology of outbreak-associated pseudorabies virus (PRV) strains in central China.

In several parts of China, there have been a large number of pseudorabies (PR) outbreaks which have devastated many swine farms even though the herds had been previously immunized with gE-deleted vaccines (Bartha-K61). The emergence of these outbreak-associated PRV strains might indicate that Bartha-K61 vaccine could not provide effective protection and poses challenges for current serologic diagnostics of anti-PRV antibodies. Here, we performed phylogenetic analyses based on partial gE, gB, and gC genes to provide information about the molecular epidemiology, diagnostics, and immune protection in these outbreak-associated PRV strains.
