Abstract: For the new wireless systems and beyond, the intelligent transportation system is considered as one of the main features that could be covered in the new research topics. Furthermore, both high-speed data transmission and data processing play a crucial role in these generations. Our work covers two main propositions in order to attain an improvement in such intelligent systems performance. A clustering algorithm is proposed and presented for grouping mobile nodes based on their speeds with some modified head assignments processes. This will be combined with a parallel-processing technique that enhances the QoS. Mainly, this work concerns enhancing the V2V data transmission and the processing speed. Thus, a wavelet processing stage has been imposed to optimize the transmitted power phenomenon. In order to check the validity of such a proposition, five main efficiency factors have been investigated; namely complementary cumulative distributions, bit rates, energy efficiency, the lifetime of cluster head, and the ordinary nodes reattaching-head average times.

Abstract: An intelligent transportation system is considered as one of the main features of the new generation wireless systems, where both high-speed data transmission and processing play a crucial role. This work presents two propositions in order to attain the performance improvement for both data transmission and processing speed. Thus, the presented work consists of deriving a clustering algorithm based on a weighting algorithm for the head assignments processes and emphasizing the parallel-processing technique based on a variety of wavelet baby functions, respectively. Accordingly, both of the data transmission speed and power will be examined. In order to verify the findings, a simulation has been done and compared with the following clustering algorithms; namely DMAC, PC, DBC, and Lower-ID DCA. This comparison is based on the following factors; namely, efficiency factors involved in this investigation; namely complementary cumulative distributions, bit rates, energy efficiency, the cluster head lifetime and the ordinary nodes reattaching-head average times. The depicted results for the cluster head duration at 20 km/s show remarkable system stability based on both the clustering overhead and the cluster head duration. The attained improvements reach the53% and 88.4% over the DBC work and the Lowest-ID DCA work, respectively.

Abstract: Autonomous wheelchairs are important tools to enhance the mobility of people with disabilities. Advances in computer and wireless communication technologies have contributed to the provision of smart wheelchairs to suit the needs of the disabled person. This research paper presents the design and implementation of a voice-controlled electric wheelchair. This design is based on voice recognition algorithms to classify the required commands to drive the wheelchair. An adaptive neuro-fuzzy controller has been used to generate the required real-time control signals for actuating motors of the wheelchair. This controller depends on real data received from obstacle avoidance sensors and a voice recognition classifier. The wheelchair is considered as a node in a wireless sensor network in order to track the position of the wheelchair and for supervisory control. The simulated and running experiments demonstrate that, by combining the concepts of soft-computing and mechatronics, the implemented wheelchair has become more sophisticated and gives people more mobility.

Abstract: A cross-sectional study was carried out on a sample of 379 horses to determine the seroprevalence of Neospora spp. in Jordan using the indirect fluorescent antibody test. Five variables, namely locality (n= 10), climatic zone (n= 4), age group (n= 3), gender, and breed were tested as risk factors for Neospora–immunoglobulin (Ig) G seropositivity at four cutoff titers (1: 50, 1: 200, 1: 400, and 1: 800) using univariate and multivariate logistic regression analyses. A total of 122 (32%; 95% CI: 28, 37) sera samples had anti-Neospora–IgG at a cutoff titer of 1: 50. Increased Neospora–IgG seropositivity was found in horses in three localities (Madaba, Zarka, and Petra) and was associated with the following variables: cool temperate climate; age> 14 years; and female gender. Seropositivity was found among horses from Madaba at all cutoff titers, Zarka at titers> 1: 200, and Petra at titers< 1> 14 years were found to be associated with seropositivity at titers≥ 1: 200. Female gender was associated with high seropositivity at> 1: 800.

Research Title: Homozygous TAF1C variants are associated with a novel childhood-onset neurological phenotype

Abstract: TATA‐box binding protein associated factor, RNA polymerase I subunit C (TAF1C) is a component of selectivity factor 1 belonging to RNA polymerase I (Pol I) transcription machinery. We report two unrelated patients with homozygous TAF1C missense variants and an early onset neurological phenotype with severe global developmental delay. Clinical features included lack of speech and ambulation and epilepsy. MRI of the brain demonstrated widespread cerebral atrophy and frontal periventricular white matter hyperintensity. The phenotype resembled that of a previously described variant of UBTF, which encodes another transcription factor of Pol I. TAF1C variants were located in two conserved amino acid positions and were predicted to be deleterious. In patient‐derived fibroblasts, TAF1C mRNA and protein expression levels were substantially reduced compared with healthy controls. We propose that the variants impairing TAF1C expression are likely pathogenic and relate to a novel neurological disease. This study expands the disease spectrum related to Pol I transcription machinery, associating the TAF1C missense variants with a severe neurological phenotype for the first time.

Abstract: The conventional SC transdermal insulin injections may create some obstacles to be the preferred technique for diabetic patients, such as pain, needle phobia, skin irritation, bruising at the injection site, and skin hardness, etc. For this purpose, this study has been conducted on "A survey on the potential awareness for the delivery of insulin using transdermal microneedle array in Jordan" involving a sample size of 400 diabetic patients. The questionnaire consists of 17 questions that asked for some problems associated with the conventional SC transdermal injections, a brief introduction for MN technology and acceptance of microneedle patches in the future. Data analysis was carried out using SPSS version 23. It was found that 75.3% of the sample population used insulin on a regular basis and 39.3% was needle phobic. In conclusion, 85.5% of patients preferred to use microneedle for insulin delivery for controlling glucose levels. More clinical trials should be performed to develop microneedle technologies for insulin delivery.

Abstract: Background and Aim: The beta toxin is causing the most severe Clostridium perfringens-related diseases. This work was dedicated to developing a vaccine against beta toxin using C. perfringens type C (NCTC 3180). Materials and Methods: The crude toxoid harvest contained 710 limits of flocculation (Lf)/mL. The vaccine was formulated. Each 1 mL of the final vaccine product contained at least 50 Lf/mL of beta toxoids, 0.2 mL 3% aluminum hydroxide gel (equivalent to 5.18 mg of aluminum), <0>0.05). Conclusion: The research showed a procedure for the manufacturing process of the vaccine against C. perfringens beta toxins with a feasible quantity and the vaccine described here showed to be effective in eliciting levels of neutralizing antibodies higher than required by international standards. In addition, the vaccine was stable up to 30 months. Thus, it may represent an effective and safe for preventing C. perfringens-related diseases in rabbits and cattle, although further studies to prove its efficacy in the field on other farm animals are still needed.

Abstract: Background: Increased attention has been focused on the continuous development and improvement of mesalamine colonic specific delivery systems, for the effective treatment of inflammatory bowel diseases; thus enhancing therapeutic efficacy and reducing potential side effects. Mesalamine is a class IV drug, according to the Biopharmaceutics Classification System, used usually to treat inflammation associated with colon related diseases such as Crohn’s disease and ulcerative colitis. Main text An ideal colon targeting system aims to deliver a therapeutic agent, selectively and effectively, to the colon. This system should ideally retain the drug release in the upper GI tract (stomach and small intestine); while trigger the drug release in the colon. Several approaches have been used to fabricate formulations to achieve a colon specific delivery of mesalamine such as; time dependent, pH responsive, enzymatic/microbial responsive and ultrasound mediated approaches. This overview outlines the recent advances in mesalamine-colon delivery approaches for the potential treatment of ulcerative colitis and Crohn’ disease. Conclusion: A combined pH-time dependent delivery system can improve mesalamine colonic drug delivery via employing carriers capable of retarding mesalamine release in the stomach and delivering it at predetermined time points after entering the intestine. The existence of specific enzymes, produced by various anaerobic bacteria present in the colon advocates the advantage of designing enzyme sensitive systems and combining it with pHtime dependent system to improve mesalamine colonic delivery. The use of ultrasound has shown promises to effectively treat inflammatory bowel diseases.
