Approximately 30% of pregnancies after implantation end up in spontaneous abortions, and 50% of them are caused by chromosomal abnormalities. However, the spectrum of genomic copy number variants （CnVs） in products of conception （POC） and the underlying gene- dosage-sensitive mechanisms causing spontaneous abortions remain largely unknown. In this study, array comparative genornic hybridiza- tion （aCGH） analysis was performed as a salvage procedure for 128 POC culture failure （POC-CF） samples and as a supplemental procedure for 106 POC normal karyotype （POC-nk） samples. Chromosomal abnormalities were detected in 10% of POC-CF and pathogenic CnVs were detected in 3.9% of POC-CF and 5.7% of POC-nk samples. Compiled results from this study and relevant case series through a literature review demonstrated an abnormality detection rate （ADR） of 35% for chromosomal abnormalities in POC-CF samples, 3.7% for pathogenic CnVs in POC-CF samples, and 4.6% for pathogenic CnVs in POC-nk samples. Ingenuity Pathway Analysis （IPA） was performed on the genes from pathogenic CnVs found in POC samples. The denoted primary gene networks suggested that apoptosis and cell proliferation pathways are involved in miscarriage. In summary, a similar spectrum of cytogenomic abnormalities was observed in POC culture success and POC-CF samples. A threshold effect correlating the number of dosage-sensitive genes in a chromosome with the observed frequency of autosomai trisomy is proposed. A rationalized approach using firstly fluorescence in situ hybridization （FISH） testing with probes of chromosomes X/Y/ 18, 13/21, and 15/16/22 for common aneuploidies and polyploidies and secondly aCGH for other cytogenomic abnormalities is recommended for POC-CF samples.

One of the most important methods that finds usefulness in various applications, such as searching historical manuscripts, forensic search, bank check reading, mail sorting, book and handwritten notes transcription, is handwritten character recognition. The common issues in the character recognition are often due to different writing styles, orientation angle, size variation(regarding length and height), etc. This study presents a classification model using a hybrid classifier for the character recognition by combining holoentropy enabled decision tree(HDT) and deep neural network(Dnn). In feature extraction, the local gradient features that include histogram oriented gabor feature and grid level feature, and grey level co-occurrence matrix(GLCM) features are extracted. Then, the extracted features are concatenated to encode shape, color, texture, local and statistical information, for the recognition of characters in the image by applying the extracted features to the hybrid classifier. In the experimental analysis, recognition accuracy of 96% is achieved. Thus, it can be suggested that the proposed model intends to provide more accurate character recognition rate compared to that of character recognition techniques used in the literature.

Donald J. Cram, the great UCLA chemist, received the nobel Prize for his discoveries about host-guest complexes . Both theoretical and experimental studies have been conducted about the nature and strength of interactions between the host and guest molecules. The concepts of constrictive binding （the activation energy of the binding process） and intrinsic binding （the free energy difference between the complex and the free host and guest molecules） were introduced to characterize different binding properties （Figure 1）

The formation and propagation of nonlinear dust acoustic waves（DAWs） as solitary and solitary/shock waves in an unmagnetized, homogeneous, dissipative and collisionless dusty plasma comprising negatively charged micron sized dust grains in the presence of free and trapped electrons with singly charged non-thermal positive ions is discussed in detail. The evolution characteristics of the solitary and shock waves are studied by deriving a modified korteweg–de Vries–Burgers（mkdV–Burgers） equation using the reductive perturbation method. The mkdV–Burgers equation is solved considering the presence（absence） of dissipation. In the absence of dissipation the system admits a solitary wave solution, whereas in the presence of dissipation the system admits shock waves（both monotonic and oscillatory） as well as a combination of solitary and shock wave solutions. Standard methods of solving the evolution equation of shock（solitary） waves are used. The results are discussed numerically using standard values of plasma parameters. The findings may be useful for better understanding of formation and propagation of waves in astrophysical plasma.
