This paper presents a High Gain, enhanced Bandwidth Patch antenna for 5G operations. The dual-band is achieved using an inset-fed feeding technique for the microstrip patch antenna, which operates at the 28/38GHz millimeter-wave band. The high gain of the patch is achieved by inserting two rectangular slots on the radiating element of the patch. The designed antenna Bandwidth is improved by incorporating three steps at the edge of the rectangular patch. The substrate used for the format is Rogers RT Duroid 5880, with a thickness of 0.508mm, loss tangent of 0.0009, and a relative permittivity constant of 2.2. Ansys HFSS software is used for the simulation. The design attained a maximum gain of 8.2dB and 7.8dB at 27.84GHz and 39.32GHz. The impedance bandwidth response of 1.46 and 4.27GHz at the respective resonating frequencies below the -10dB line of the parameters are achieved. A compact antenna is proposed with a size of 3.2x4.9x0.508 and has a high Gain with a wide Bandwidth at both bands. The proposed antenna has achieved a good performance within the operating bands, making it suitable for 5G applications.

A Compact High-Gain Microstrip Patch Antenna with Improved Bandwidth for 5G Applications

Collectively, rare genetic diseases affect a significant number of individuals worldwide. In this study, we have conducted whole-exome sequencing (WES) and identified underlying pathogenic or likely pathogenic variants in five children with rare genetic diseases. We present evidence for disease-causing autosomal recessive variants in a range of disease-associated genes such as DHH-associated 46,XY gonadal dysgenesis (GD) or 46,XY sex reversal 7, GNPTAB-associated mucolipidosis II alpha/beta (ML II), BBS1-associated Bardet–Biedl Syndrome (BBS), SURF1-associated Leigh Syndrome (LS) and AP4B1-associated spastic paraplegia-47 (SPG47) in unrelated affected members from Bangladesh. Our analysis pipeline detected three homozygous mutations, including a novel c. 863 G > C (p.Pro288Arg) variant in DHH, and two compound heterozygous variants, including two novel variants: c.2972dupT (p.Met991Ilefs*) in GNPTAB and c.229 G > C (p.Gly77Arg) in SURF1. All mutations were validated by Sanger sequencing. Collectively, this study adds to the genetic heterogeneity of rare genetic diseases and is the first report elucidating the genetic profile of (consanguineous and nonconsanguineous) rare genetic diseases in the Bangladesh population.

This work proposes a dual band microstrip fed patch antenna suitable for 5G mobile networks access. The antenna resonates at 28GHz and 38GHz frequency and requires large infrastructure for implementation. Dual band response is achieved by etching a semi-circular slot in the main radiator and introducing another resonator close to this slot which radiates electromagnetic energy. The proposed antenna has a satisfactory gain at both frequency bands and shows omnidirectional radiations and is useful for mobile users and is exclusively used for microwave technology applications.

Epidermodysplasia verruciformis (EV) is an extremely rare hereditary skin disease characterized by an abnormal susceptibility to the human papilloma virus (HPV) with an increased risk of cutaneous malignancy. Here we report the first female severe EV case in Bangladesh, a 10-year-old girl with a nonsense somatic mutation impacting ANKRD26 gene.

This paper has found out optimized value of design parameters of microstrip patch antenna (MPA) at 28 GHz and 38 GHz for 5G applications. Three design parameters namely: substrate element, substrate height and feeding technique have significant effect on antenna performance. If these are not suitably elected, the 5G requirements won't be covered. This work has found out the optimized value of substrate element, substrate height and feeding technique as design parameters for designing MPA at 28 GHz and 38 GHz which fulfill the 5G requirements. In addition, a comparative observation of antenna performance is done among the antennas which are designed based on these three design parameter values. Foam as substrate element, substrate height 0.5 mm and quarter wave transformer feeding technique have been found as the best performance provider at 28 GHz and 38 GHz frequency bands as per 5G requirement. In conclusion, Single element Antenna is designed on 28 GHz and 38 GHz using aforementioned best performance provider design parameter values.

Because of the immense necessity of displaying short messages on electronic devices the segmented display system has become greatly popular. Numerous research activities are done to represent English and Bengali letters on segmented display. On the other hand, no research work is found till now for Arabic letters. This paper brings an accurate and systematic segmentation method for Arabic letters. The points covered by each segment, the segments needed for each letter, the truth table for the letter, simplified expressions and the logic circuits of the segments are given. In this paper, we have generated all the Arabic letters with understandable and proper shapes. Also, the segment-to-letter ratio is found to be less comparatively.

There will be high energy wastage and CO 2 emissions will be increased in 5G network because of dense deployment of small cell base stations. This paper brings an efficient energy management technique for 5G green small cell network which switches on as such number of antennas from the array as needed. This is done by monitoring and counting the amount of data traffic within the area of the small cell. It is shown that the proposed scheme is capable to improve energy saving significantly. We have found that the scheme consumes up to 96.875% less energy than without energy management technique. Besides, the emission of CO 2 is reduced by 2.3166kg per day when the small cell is operated by a diesel power source and for all kinds of power sources on average CO 2 emission can be reduced by 1.612 kg per day.

Audio system for a classroom is one of the most important parts of effective teaching and learning process in modern ages due to indoor and outdoor noise level and articulation loss of delivered speeches at distant students. The knowledge of sound engineering is essential for designing an audio system for classrooms at all levels of education. In this paper, we have discussed a novel customized exploded cluster of speakers along with automatic volume control upon detection of students seated at individual coverage areas of each speaker. We have considered all the factors of the room along with a real-time calculation of all the equations set by sound engineers and found the values satisfactory with allowed levels prescribed by world health organization. Finally, we have implemented our proposed cluster of sound system and got expected outcomes, which can be undoubtedly installed for any classroom for healthy and comfortable sound for each student in the class.
