Enhancement of Detection of Diabetic Retinopathy Using Harris Hawks Optimization with Deep Learning Model
1. Introduction:
Diabetes mellitus (DM) is a most important worldwide
health concern, which causes a range of long-term complete
impairments that have a significant influence on the patient
and society, as the illness usually upsets people in their best
fruitful ages. As per the latest alarming statistical facts released
by the International Diabetes Federation (IDF) Diabetes
Atlas 2021 document [1], there are 537 million (1 in
10) adults (aged 20–79 years) living with diabetes mellitus
worldwide in 2021. is number is anticipated to rise to 643
million (1 in 9 adults) by 2030 and 784 million (1 in 8 adults)
by 2045. Also, 81% (4 in 5 adults) with diabetes are living in
middle- and low-income countries. Around 6.7 million
deaths (1 every 5 seconds) occurred in 2021 due to DM. An
assessed 44% of adults (240 million) living with diabetes in
middle and low-income countries are left undiagnosed. In
2021, the global health expenditure caused by diabetes alone
is evaluated at USD 996 billion with an increase of 316% over
the last 15 years. Around 541 million (1 in 10) adults
worldwide have been positioned at high risk of emerging
type 2 diabetes due to diminished glucose tolerance levels.
e top 10 countries with the maximum number of people
with diabetes account for 68% of adults with diabetes [2].

A New Handover Management Model for Two-Tier 5G Mobile Networks Mohammad Arifin Rahman Khan1,*, Mohammed Golam Kaosar2, Mohammad Shorfuzzaman3 and Kire Jakimoski4
Abstract: There has been an exponential rise in mobile data traffic in recent
times due to the increasing popularity of portable devices like tablets, smartphones,
and laptops. The rapid rise in the use of these portable devices has
put extreme stress on the network service providers while forcing telecommunication
engineers to look for innovative solutions to meet the increased
demand. One solution to the problem is the emergence of fifth-generation
(5G) wireless communication, which can address the challenges by offering
very broad wireless area capacity and potential cut-power consumption. The
application of small cells is the fundamental mechanism for the 5Gtechnology.
The use of small cells can enhance the facility for higher capacity and reuse.
However, it must be noted that small cells deployment will lead to frequent
handovers of mobile nodes. Considering the importance of small cells in 5G,
this paper aims to examine a new resource management scheme that can work
to minimize the rate of handovers formobile phones through careful resources
allocation in a two-tier network. Therefore, the resource management problem
has been formulated as an optimization issue thatwe aim to overcome through
an optimal solution. To find a solution to the existing problem of frequent
handovers, a heuristic approach has been used. This solution is then evaluated
and validated through simulation and testing, during which the performance
was noted to improve by 12% in the context of handover costs. Therefore,
this model has been observed to be more efficient as compared to the existing
model.
