Control and Filtering for Discrete Linear Repetitive Processes with H infty and ell 2--ell infty Performance
No full textRepetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length. On each pass an output, termed the pass profile, is produced which acts as a forcing function on, and hence contributes to, the dynamics of the next pass profile. This can lead to oscillations which increase in amplitude in the pass to pass direction and cannot be controlled by standard control laws. Here we give new results on the design of physically based control laws for the sub-class of so-called discrete linear repetitive processes which arise in applications areas such as iterative learning control. The main contribution is to show how control law design can be undertaken within the framework of a general robust filtering problem with guaranteed levels of performance. In particular, we develop algorithms for the design of an H? and dynamic output feedback controller and filter which guarantees that the resulting controlled (filtering error) process, respectively, is stable along the pass and has prescribed disturbance attenuation performance as measured by and – norms
Participation of c-FLIP in NLRP3 and AIM2 inflammasome activation
No full textCellular FLICE-inhibitory protein (c-FLIP) is an inhibitor of caspase-8 and is required for macrophage survival. Recent studies have revealed a selective role of caspase-8 in noncanonical IL-1 beta production that is independent of caspase-1 or inflammasome. Here we demonstrated that c-FLIPL is an unexpected contributor to canonical inflammasome activation for the generation of caspase-1 and active IL-1 beta. Hemizygotic deletion of c-FLIP impaired ATP-and monosodium uric acid (MSU)-induced IL-1 beta production in macrophages primed through Toll-like receptors (TLRs). Decreased IL-1 beta expression was attributed to a reduced activation of caspase-1 in c-FLIP hemizygotic cells. In contrast, the production of TNF-alpha was not affected by downregulation in c-FLIP. c-FLIPL interacted with NLRP3 or procaspase-1. c-FLIP is required for the full NLRP3 inflammasome assembly and NLRP3 mitochondrial localization, and c-FLIP is associated with NLRP3 inflammasome. c-FLIP downregulation also reduced AIM2 inflammasome activation. In contrast, c-FLIP inhibited SMAC mimetic-, FasL-, or Dectin-1-induced IL-1 beta generation that is caspase-8-mediated. Our results demonstrate a prominent role of c-FLIPL in the optimal activation of the NLRP3 and AIM2 inflammasomes, and suggest that c-FLIP could be a valid target for treatment of inflammatory diseases caused by over-activation of inflammasomes

The species is easily distinguished from other species in C. gladiata complex due to the paler ground coloration of the wings and the more contrasting forewing medial region, the less curved transversal lines on both wings, and the medial part of the corpus bursae, which is incised with longitudinal wrinkles. Distribution and phenology. Endemic to Taiwan. The adults occur from June to August.Published as part of Wu, Shipher, Owada, Mamoru & Wang, Min, 2019, Review of Cidariplura Butler, 1879 (Lepidoptera, Erebidae, Herminiinae).

Nocardioides intraradicalis sp. nov., isolated from the roots of Psammosilene tunicoides W. C. Wu et C. Y. Wu
No full textA Gram-stain-positive, non-spore-forming and non-motile strain designated YIM DR1091Twas isolated from the roots of Psammosilene tunicoides W. C. Wu et C. Y. Wu collected from Gejiu, Yunnan, China. The taxonomic position of strain YIM DR1091 was investigated by polyphasic approaches. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain YIM DR1091Tis a member of the genus Nocardioides. Strain YIM DR1091Twas closely related to Nocardioides pyridinolyticus OS4T, Nocardioides caricicola YC6903T, Nocardioides hankookensis DS-30Tand Nocardioides aquiterrae GW-9Tand had a pairwise 16S rRNA gene sequence similarities of 97.6, 97.5, 97.2 and 97.2%, respectively. DNA:DNA relatedness values between strain YIM DR1091Tand related type strains JCM 10369T, JCM 17686T, JCM 15302Tand JCM 11813Twere found to be 44.9±1.7, 50.2±1.3, 46.8±0.9 and 43.0±0.2% respectively. The respiratory menaquinone for strain YIM DR1091Twas MK-8 (H4) while the major fatty acids (>5%) were iso-C16:0, C17:1ω8c，C17:0, iso-C15:0and iso-C14:0. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol and three unidentified phospholipids. Whole-cell hydrolysates contained mannose, ribose, glucose and galactose, along withLL-diaminopimelic acid as the diagnostic diamino acid in the peptidoglycan. The DNA G+C content was 74.6 mol%. Phenotypic, phylogenetic and chemotaxonomic data indicated that strain YIM DR1091Trepresents a novel species of the genus Nocardioides, for which the name Nocardioides intraradicalis sp. nov. is proposed. The type strain is YIM DR1091T(=JCM 30632T=CGMCC4.7251T).open

(2013) described C. shanmeii with the illustration of the holotype of C. shanmeii, however the illustrated structures in Wu et al. (2013: figs 37, 38, male; 64, female; 69, labial palpus; 80, male foreleg), actually belong to the new species, C. hbun sp. nov., described below. Diagnosis. Externally C. shanmeii and C. hbun are difficult to be separated, but the former species can be distinguished from the latter by the narrowed white forewing discocellular spot, rather than a wider and more yellowish-white spot; the costal process of the valva is digitiform rather than stouter and curved downwards; the distinctively shorter distal portion of valva rather than nearly equal in length as costal process; the digitiform, straight costal process rather than curved ventrally and tapering; the saccular process is extremely small and curved rather than robust and rod-like pointing parallelly with distal portion of valva; the ductus bursae is extremely narrowed compared to the moderate width of other species in the complex. Re-description. Due to the existence of specimens belonging to both C. shanmeii and C. hbun sp. nov. in the paratype series of C. shanmeii (sensu Wu & Owada, in Wu et al., 2013), we re-describe C. shanmeii herein to clarify the identity of that species.

Valva trifurcate, costal process, straight and digitiform, distal portion of valva broad, saccular process short, curved and digitiform. Juxta plate-like, transtilla indistinct. Aedeagus stout, straight, 1. 25 X longer than valva; vesica densly scobinate without cornutus. Female genitalia (Fig. 53)—Papillae anales membranous with short hair-like setae; both pairs of apophyses slender, moderate length; ductus bursae as long as corpus bursae, with a pair of slender lateral sclerites. Corpus bursae elliptical, basal half part surrounded by dense internal spinose patch; ductus seminalis arising from lateral base of corpus bursae, broadened and coiled basally. Distribution and phenology. Endemic to Taiwan. The adults occasionally occur from March to November.Published as part of Wu, Shipher, Owada, Mamoru & Wang, Min, 2019, Review of Cidariplura Butler, 1879 (Lepidoptera, Erebidae, Herminiinae).

Can one assess the pi character of a C-C bond with the help of the NMR spin-spin coupling constants?
No full textMeasured one-bond spin-spin coupling constants (SSCC) (1)J(CC) can be used to describe the nature of the C-C bond, provided one is able to separate the various coupling mechanisms leading to (1)J(CC). The Fermi-contact (FC) term probes the first order density at the positions of the coupling nuclei, whereas the noncontact terms (the paramagnetic spin orbit (PSO) and the spin-dipole (SD) terms) probe the pi character of the C-C bond (the diamagnetic spin orbit (DSO) term can mostly be neglected). A model is tested, in which the value of the FC(CC) term is estimated with the help of measured SSCCs (1)J(CH). The difference between the measured J(CC) and the estimated FC(CC) values, Delta(CC) = PSO(CC) + SD(CC) + DSO(CC), provides a semiquantitative measure of the pi character of a C-C multiple bond. The applicability and limitations of this approach are discussed by partitioning the four Ramsey terms of the SSCC (1)J(CC) into one- and two-orbital contributions. The FC, PSO, and SD terms of (1)J(CC) are explained and analyzed with regard to their relationship to other C-C bond properties. It is shown that empirical relationships between measured SSCCs and the s character of a bond need reconsideration
