Abstract: Protein homeostasis is tightly regulated by the ubiquitin proteasome pathway. Disruption of this pathway gives rise to a host of neurological disorders. Through whole exome sequencing (WES) in families with neurodevelopmental disorders, we identified mutations in PSMD12, a core component of the proteasome, underlying a neurodevelopmental disorder with intellectual disability (ID) and features of autism spectrum disorder (ASD). We performed WES on six affected siblings from a multiplex family with ID and autistic features, the affected father, and two unaffected mothers, and a trio from a simplex family with one affected child with ID and periventricular nodular heterotopia. We identified an inherited heterozygous nonsense mutation in PSMD12 (NM_002816: c.367C>T: p.R123X) in the multiplex family and a de novo nonsense mutation in the same gene (NM_002816: c.601C>T: p.R201X) in the simplex family …

Abstract: Serological detection of Neospora spp. was carried out on 445 Jordanian women with miscarriage, using the indirect fluorescent antibody test and N. caninum antigen. The type of hospital, age, cat and dog contact, raw meat and wild plant consumptions, number of miscarriages and stillbirths, were tested as risk factors for the seroprevalence using univariable and multivariable logistic regression analyses. At cutoff titers of 1:200 and 1:400 the seroprevalences of Neospora were 25% and 6% for IgG and 12% and 7% for IgM, respectively. Neospora-IgG-seropositivity was associated with having a dog in the household or in the immediate environment with odds ratios of 2.6 and 4.1 respectively, and had stillbirth with an odds ratio of 0.1. Neospora-IgM-seropositivity was associated with women with miscarriage visiting a private hospital. The current results provide serological and epidemiological evidence for the emerging zoonotic potential of Neospora species infection to be categorized as a level one zoonosis.

Research Title: On the Parallel Processing for Wireless Sensors Converged Network

Author: Qadri Jamal Al-Hamarsheh, Published Year: 2020

Abstract: This paper studies the capability of multi-parallel processing to be accommodated in machine-to-machine communications. A testbed convergence between the wireless sensor network and the wireless mobile network is performed. It deals with enhancing wireless mobile network performance. This testbed is divided into three stages; combating the peak-to-average power ratio problem, observing a real data making use of actual wireless sensors, and proposing multi-parallel processing communications. The mentioned testbed above is done in a realistic academic environment, where selected signals from those sensors are evaluated. Thus, a design improvement is detailed in terms of the peak-to-average power ratio and the efficient use of limited resources. In particular, the scope focuses on the mitigation of the nonlinear distortion and its effect on a bit error rate. The validation process is attained based on performing an extensive simulation. It is observing certain performance parameters such as the sensor lifetime, and the consumed energy. From the testbed simulation results, the proposed work shows promising results comparing to the conventional wireless sensor network. The delay reduction reaches around 85%, while the peak to average power ratio values has improved by 42.3%.

Research Title: Multiparallel Processing for Enhancing the V2V Clustering Performance

Abstract: In order to support the demand of the users in the new generation wireless systems (such as the smart interaction between the mobile devices and the mobile human), the resources of the intelligent the transportation system should be utilized efficiently. Thus, the network structure adaptation due to the rapid changes in such a communication process should be investigated. This is in addition to save the direct impact of network resources such as high-speed data transmission and data processing. Based on the Vehicular Ad hoc Network (VANET) standard and (IEEE 802.11p), two main propositions have been examined to attain the improvement in such intelligent systems performance. In this paper, we improved the QoS and proposed a clustering algorithm named MP-RC-MBOFDM. It groups the mobile nodes based on their speeds with some modified head assignments processes. This will be combined with a parallel-processing technique and a wavelet processing stage to optimize the transmitted power phenomenon. The simulation results of five main efficiency factors that have been involved; namely complementary cumulative distributions, bit rates, energy efficiency, the cluster head life time and the ordinary nodes reattaching-head average times; show the feasibility of the new proposition in the V2V data transmission.

Abstract: in this work, a comparison has been made among different proposed algorithms in order to improve the performance of a power consumption wireless network. They are used to combat one of the Orthogonal Frequency Division Multiplexing (OFDM) technique drawbacks, which are considered as a key technique in enhancing the new era of wireless systems' quality of service (QoS). Therefore, three different propositions have been investigated and covered by this work and classified as linear coding based, wavelet transformation based, PWM based. Furthermore, a MATLAB program has been run to check their performance and covers two different criteria; the curves of CCDF and the SER curves. This is in order to reduce the Peak-to-Average Power Ratio (PAPR) effect.

Abstract: In this work, a proposition has been studied in order to check the Terrestrial Digital Video Broadcasting (DVB-T) enhancement. It deals with overcoming the effect of the Peak-to-Average Power Ratio (PAPR) drawback on wireless systems? performances. For this purpose, a special averaging technique has been introduced in this work and consists of three different stages; signal's noise removal, adaptively peak detection, and averaging filtration, consequently. In order to check the work efficiency, a MATLAB simulation has been conducted at the same bandwidth and channel conditions to deals with both BER curves and CCDF curves. As a result, the proposed work shows promising results over the proposed work in the literature and over our previously published work. The proposed work gives extra immunity against the channel noise reaches up to 25% over the literature. Furthermore, it gives an extra 15% reduction in combatting the PAPR effect.
