Background and Aim: In a Bimodal fitting, one ear is stimulated acoustically with a hearing aid and the other is stimulated electrically with a cochlear implant. This paper provides a brief summary of the concept of Bimodal fitting, binaural hearing and its importance, the hearing benefits of binaural hearing in Bimodal fitting, candidacy and hearing aid adjustment in Bimodal fitting cases. Recent Findings: Researches have shown that Bimodal fitting offers a wide range of hearing benefits over unilateral cochlear implants, such as better speech perception in noise, better musical perception, and a better understanding of pitch and tone perception and naturalness of sound perception. Conclusion: Considering the binaural hearing advantages in Bimodal fitting users, it can be concluded that users of unilateral cochlear implants who have measurable residual hearing in their non-implanted ear can use a hearing aid in that ear and enjoy binaural hearing advantages. The hearing aid should be fitted in a way to complement the information obtained through cochlear implantation.

Background and Aim: Difficulty in perception of speech in noise is one of the main complaints of hearing-impaired people. Due to profound hearing loss in cochlear implant (CI) users, they need higher signal-to-noise ratio for a better perception. Bimodal fitting is a preferred way for CI users because it prevents auditory nerve degeneration, is a complement of frequency range at the opposite ear, an is less invasive to provide binaural hearing. Acceptable noise level (ANL), as a reliable test to assess noise tolerance, has not yet been used in comparing children with Bimodal hearing and CI. This study aimed to determine whether Bimodal fitting can help CI children tolerate more noise. Methods: This descriptive-analytical study was conducted on 13 children with unilateral CI and Bimodal hearing. Audiometry test was performed at aided and non-aided conditions. Then, their noise tolerance was assessed by the Persian version of ANL test. Results: Bimodal hearing resulted in statistically significant increase in ANL. The mean of ANL at unilateral CI and Bimodal hearing conditions were 6. 15±, 2. 90 and 4. 77±, 1. 70, respectively. Conclusion: Bimodal fitting lead to more noise tolerance in unilateral CI children due to the combination of binaural summation and binaural release from masking.

The petrology of Bimodal magmatism of Desu series in Horjand area, a rather disorder diapir like complexes of Desu sedimentary-igneous series (Early Cambrian) can be found. In the field studies, it was found that the igneous rocks of the series are mostly basic and felsic lavas which are accompanied by small intrusive bodies. In this area, Bimodal magmatism happened. These igneous rocks are in two basic and acidic families and have no intermediate components. The basic rocks are mostly basalts with some microgabbro and monzo-gabbro which are in fact intrusive category of basalt. Acidic rocks are mostly trachytes and trachylatites with some microsyenites. The additive natural trend of major, minor and trace elements phases in melt shows not only the genetical relationship between these two categories but also a compositional gap between them. The geochemical- petrological discrimination diagrams show transitionally-alkaline or transalkali parent magma for the complex.

We consider the real polynomials of degree d + 1 with a fixed point of multiplicity d ≥,2. Such polynomials are conjugate to fa, d(x) = axd(x −,1) + x, a ∈,R \ {0}. In this family, the point 0 is always a non-hyperbolic fixed point. We prove that for given d, d ′, , and a, where d and d ′,are positive even numbers and a belongs to a special subset of R−, , there is a ′,< 0 such that fa, d is topologically conjugate to fa′, , d′, . Then we extend the properties that we have studied in case d = 2 to this family for every even d > 2.

Bimodal imaging combines two imaging modalities in order to benefit from their advantages and compensate the limitations of each modality. This technique could accurately detect diseases for diagnostic purposes. Nanoparticles simultaneously offer diagnostic data via various imaging modalities owing to their unique properties. Moreover, Bimodal nanoprobes could be incorporated into theranostic systems for the design of multifunctional agents. Magnetic resonance imaging (MRI) and computed tomography (CT) are frequently used as noninvasive imaging modalities. These powerful, noninvasive diagnostic techniques used for the imaging of soft and hard tissues, respectively. However, MRI has low sensitivity and is not suitable for the imaging of bony structures. On the other hand, low soft tissue contrast is a major limitation of CT. Therefore, the development of various contrast agents that are proper for Bimodal MRI/CT nanoprobes could largely influence modern medicine. This review aimed to specifically focus on the imaging properties of Bimodal MRI/CT nanoprobes and their biomedical applications.
