A uniform experimental design(UED)is an extremely used powerful and efficient methodology for designing experiments with high-dimensional inputs,limited resources and unknown underlying models.A UED enjoys the following two significant advantages:(i)It is a robust design,since it does not require to specify a model before experimenters conduct their experiments;and(ii)it provides uniformly scatter design points in the experimental domain,thus it gives a good representation of this domain with fewer experimental trials(runs).Many real-life experiments involve hundreds or thousands of active factors and thus large UEDs are *** large UEDs using the existing techniques is an NP-hard problem,an extremely time-consuming heuristic search process and a satisfactory result is not *** paper presents a new effective and easy technique,adjusted Gray map technique(AGMT),for constructing(nearly)UEDs with large numbers of four-level factors and runs by converting designs with s two-level factors and n runs to(nearly)UEDs with 2^(t−1)s four-level factors and 2tn runs for any t≥0 using two simple transformation *** justifications for the uniformity of the resulting four-level designs are given,which provide some necessary and/or sufficient conditions for obtaining(nearly)uniform four-level *** results show that the AGMT is much easier and better than the existing widely used techniques and it can be effectively used to simply generate new recommended large(nearly)UEDs with four-level factors.

A carbuncle cure for the harten-Lax-van Leer contact(hLLc)scheme using a novel velocity-based sensor

引用

Applied Mathematics and Mechanics(English Edition) 2021年第9期42卷 1259-1278页

作者： U.S.VEVEK B.ZANG T.h.NEW Department of Mechanical Materials and Aerospace EngineeringUniversity of LiverpoolLiverpool L693BXUnited Kingdom Department of Aerospace Engineering University of BristolBristol BS81TRUnited Kindgdom School of Mechanical and Aerospace Engineering Nanyang Technological University50 Nanyang AvenueSingapore 639798Singapore

A hybrid numerical flux scheme is proposed by adapting the carbunclefree modified harten-Lax-van Leer contact(hLLcM) scheme to smoothly revert to the harten-Lax-van Leer contact(hLLc) scheme in regions of shear. This hybrid scheme, referred to as the hLLcT scheme, employs a novel, velocity-based shear sensor. In contrast to the non-local pressure-based shock sensors often used in carbuncle cures, the proposed shear sensor can be computed in a localized manner meaning that the hLLcT scheme can be easily introduced into existing codes without having to implement additional data structures. Through numerical experiments, it is shown that the hLLcT scheme is able to resolve shear layers accurately without succumbing to the shock instability.

Animal Nutrition 2019年第1期5卷 22-31页

作者： Vasileios Paraskeuas Konstantinos c.Mountzouris Department of Nutritional Physiology and Feeding Agricultural University of Athens

The present study assessed the effects of cereal type and the inclusion level of a phytogenic feed additive(PFA) on broiler ileal and cecal gut microbiota composition, volatile fatty acids(VFA) and gene expression of toll like receptors(TLR), tight junction proteins, mucin 2(MUc2) and secretory immunoglobulin A(sIgA). Depending on cereal type(i.e. maize or wheat) and PFA inclusion level(i.e. 0, 100 and 150 mg/kg diet), 450 one-day-old male broilers were allocated in 6 treatments according to a 2 × 3 factorial arrangement with 5 replicates of 15 broilers each, for 42 d. Significant interactions(P 0.05) between cereal type and PFA were shown for cecal digesta Bacteroides and clostridium cluster XIVa, ileal digesta propionic and branched VFA, ileal s IgA gene expression, as well as cecal digesta branched and other VFA molar ratios. cereal type affected the cecal microbiota composition. In particular, wheat-fed broilers had higher levels of mucosa-associated Lactobacillus(P_(cT)= 0.007) and digesta Bifidobacterium(P_(cT)cteria(P_(cT)= 0.004) and clostridia clusters I, IV and XIVa(P_(cT) 0.05),compared with maize-fed ones. In addition, cereal type gave differences in fermentation intensity(P_(cT)= 0.021) and in certain individual VFA molar ratios. Wheat-fed broilers had higher(P 0.05) ileal zonula occluden 2(ZO-2) and lower ileal and cecal TLR2 and sIgA levels, compared with maize-fed broilers. On the other hand, PFA inclusion at 150 mg/kg had a stimulating effect on microbial fermentation at ileum and a retarding effect in ceca with additional variable VFA molar patterns. In addition, PFA inclusion at 100 mg/kg increased the ileal mucosa expression of claudin 5(cLDN5)(PPFA= 0.023) and MUc2(PPFA= 0.001) genes, and at 150 mg/kg decreased cecal TLR2(PPFA= 0.022) gene expression compared with the un-supplemented controls. In conclusion, cereal type and PFA affected in combination and independently broiler gut microbiota compositio
