data visualization is the process of transforming data, information, and knowledge into visual form, making use of humans’ natural visual capabilities which reveals relationships in data sets that are not evident from the raw data, by using mathematical techniques to reduce the number of dimensions in the data set while preserving the relevant inherent properties. in this paper, we formulated d...

in recent years, the needs of the internet are felt in lives of all people.  accordingly, many studies have been done on security in virtual environment. old technics such as firewalls, authentication and encryption could not provide internet security completely; so, intrusion detection system is created as a new solution and a defense wall in cyber environment. many studies were performed on d...

the emergency medical centers are very helpful since they reduce the number of death and injuries by getting to the scenes of accidents and dealing with the case immediately. as saving one's life is the prime goal in these centers, any findings and techniques which will improve the services and ease achieving the goal will be highly welcomed. the first and the major factor in giving this kind o...

this paper considers identical parallel machines scheduling problem with past-sequence-dependent setup times, deteriorating jobs and learning effects, in which the actual processing time of a job on each machine is given as a function of the processing times of the jobs already processed and its scheduled position on the corresponding machine. in addition, the setup time of a job on each machin...

background: the protein hormone granulocyte colony-stimulating factor (gcsf) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. methods: an efficient process was developed for heterologous expression of human gcsf in e. coli bl21 (de3). the feeding rate was adjusted to achieve the maximum attainable specific growth rate under crit...

background: acute myeloid leukemia (aml) is an immunophenotypically heterogeneous malignant disease, in which cd34 positivity is associated with poor prognosis. osteopontin (opn) plays different roles in physiologic and pathologic conditions like: survival, metastasis and cell protection from cytotoxic and apoptotic stimuli. due to anti-apoptotic effect of opn in normal and malignant cells, sil...

background: granulocyte colony stimulating factors (gcsf) are high cost agents commonly recommended for primary and secondary prophylaxis of chemotherapy-induced neutropenia and febrile neutropenia. gcsfs have been shown to be beneficial in some patient subgroups, although they are probably overused in clinical settings. the american society of clinical oncology (asco) guidelines summarize curr...

The performance of the MAX -MIN ant system (MMAS) in dynamic optimization problems (DOPs) is sensitive to the colony size. In particular, a large colony size may waste computational resources whereas a small colony size may restrict the searching capabilities of the algorithm. There is a trade off in the behaviour of the algorithm between the early and later stages of the optimization process. ...

honeybee is a pollinator that has prominent role in agriculture products and nourishment for human. so, the most number of studies like genetic improvement were done on honeybee. recent advances in knowledge of molecular genetics of bee emphasize the potential for using genetic markers to select favored traits. this research was done to determine polymorphism of loci of first foraging age (aff)...

Birdsong is culturally transmitted, and geographical variations of song have been found in several songbird species. There evidence that such dialects contribute to reproductive isolation through variation female preference. In the wild, there no report consistent populations zebra finches. However, under laboratory conditions, we were able artificially create different colony-wide dialects. th...
