The dendritic cell algorithm(DCA)is an excellent prototype for developing Machine Learning inspired by the function of the powerful natural immune *** many parameters increase complexity and lead to plenty of criticism in the signal fusion procedure of *** loss function of DCA is ambiguous due to its *** reduce the uncertainty,several researchers simplified the algorithm program;some introduced gradient descent to optimize parameters;some utilized searching methods to find the optimal parameter ***,these studies are either time-consuming or need to be revised in the case of non-convex *** overcome the problems,this study models the parameter optimization into a black-box optimization problem without knowing the information about its loss *** study hybridizes bayesian optimization hyperband(BOHB)with DCA to propose a novel DCA version,BHDCA,for accomplishing parameter optimization in the signal fusion *** BHDCA utilizes the bayesian optimization(BO)of BOHB to find promising parameter configurations and applies the hyperband of BOHB to allocate the suitable budget for each potential *** experimental results show that the proposed algorithm has significant advantages over the otherDCAexpansion algorithms in terms of signal fusion.

Holttumochloa has previously only been recorded from Malaysia. Here we describe and illustrate a new species, Holttumochloa hainanensis sp. nov., from the lowland montane forests of Diaoluo Mountain on the Island of Hainan, South China. Morphologically, H. hainanensis is similar to Holttumochloa korbuensis,but can be clearly distinguished from it in having larger culms covered by white wax, longer leaf blades,larger pseudospikelets and anthers. Furthermore, molecular phylogeny based on the nuclear gene GBSSI corroborates the identification of the new species and its affinity. The biogeographical significance of the new record of Holttumochloa in South China is also highlighted in this study.

Activation of antigen presenting cells(APC) is crucial in initiating inflammation and alloreaction during acute graftversus-host disease(aGVHD).Interleukin-1 receptor-associated kinase 1(IRAK1) regulates activation of *** of IRAK1 might decrease APC activation and *** tested this hypothesis by giving allotransplant mice a selective IRAK1 inhibitor ***-X-119-01 increased survival and decreased aGVHD of ***-X-119-01 decreased proportions of Th1 cells and Tc1 cells in the aGVHD model and in the in vitro mixed lymphocyte reaction(MLR).The IRAK1 inhibitor suppressed not only the alloreaction elicited from combined T-cell and APC,but also the activation of T-cell and APC ***1 inhibition did not impair granzyme B production in T cells or the allotransplant-related graft-versus-lymphoma(GVL) effect against A20 lymphoma *** conclusion,we show selective IRAK1 inhibition ameliorates murine aGVHD but preserves GVL effect.
