Caking of soybean meal during storage and the resultant difficulty in discharging from storage bin is a practical problem in animal feed‐related industries. This study investigated the physicochemical factors related to soybean meal flowability and the effect of anticaking agents. Results showed the soybean meal had a D50 of 389.1 µm and a D90 of 1.098 µm. The equilibrium relative humidity of soybean meal at various ambient temperatures ranged from 57 % to 69 %. Moisture had a major influence on soybean meal flowability and the critical moisture content for loss of free flow capacity was around 17.81 % (wet basis, wb). Soybean meal was characterized as amorphous by X‐ray diffraction analysis, and its glass transition temperature is greatly affected by the moisture content. The addition of silicon dioxide helps keep soybean meal free flowing when stored at a relative humidity of 90 % and a temperature of 45 °C possibly due to its low affinity for moisture. Overall, moisture absorption is perceived as the main factor causing the occurrence of caking of soybean meal. [ABSTRACT FROM AUTHOR]

Introduction: Dyskeratosis congenita is a rare genetic disorder characterized by abnormalities of the skin, nails, and oral mucosa. Retinal involvement in this condition is uncommon. Here, we present a case of a young male patient diagnosed with presumptive cytomegalovirus retinitis, ultimately found to be concomitant with dyskeratosis congenita. Case Presentation: A non-HIV-infected young male with recurrent infections, including aspergillus pneumonia and pneumocystis pneumonia, presented with presumptive cytomegalovirus retinitis in both eyes. Systemic manifestations included cutaneous hyperpigmentation, nail dystrophy, and oral mucosal leukoplakia. Genetic testing revealed a mutation in the DKC1 gene. The final diagnosis was dyskeratosis congenita complicated by presumptive cytomegalovirus retinitis. Conclusion: Cytomegalovirus retinitis can serve as an ocular complication of dyskeratosis congenita. When a patient presents with cytomegalovirus retinitis, a comprehensive systematic examination should be conducted as it indicates severe immunodeficiency. [ABSTRACT FROM AUTHOR]

Compared with the uniform linear array (ULA) under the same physical array element, the coprime array can obtain a higher degree of freedom and a larger array aperture, so it has received extensive attention from scholars in recent years. Based on the idea of interference plus noise covariance matrix (INCM) reconstruction, this study proposed a robust adaptive beamforming algorithm using the coprime array. In the virtual array generated by the coprime array, the authors prove from the perspective of virtual signals that the constructed Toeplitz matrix is equivalent to a virtual ULA with more array elements. Subsequently, a high‐resolution subspace algorithm is used to estimate the direction of arrival (DOA) of the signals, and the estimated DOA is used to reconstruct the direction vector (DV) of the coprime array. Through the eigenvalue decomposition of the reconstructed Toeplitz matrix, the corresponding relationship between the eigenvalue and the power is deduced, and the signals and noise power are estimated using the eigenvalue. Finally, combine the DV of the desired signal and the reconstructed INCM to calculate the weight vector of the proposed algorithm. The simulation results prove the superiority and effectiveness of the algorithm. [ABSTRACT FROM AUTHOR]
