Anti-Eavesdropping for Connected Cars
Authors: Kavaiya Sagar , Patel Dhaval
Published: March 2022

Physical layer security (PLS) is an essential way to provide security to users in wireless networks against active or passive attacks. The quantification of the provided security is measured through secrecy outage probability and outage probability. For cognitive vehicular networks (CVN), PLS can increase the amount of the quality of services in infotainment applications. Due to the broadcast nature of the wireless channels, it is challenging to achieve the perfect secrecy between the transmitting and receiving nodes. Furthermore, in CVN, when resources are being shared in an underlay manner, the need arises to find the highest and lowest achievable quantification of performance measures for poor fading scenarios. The knowledge of the maximum achievable performance helps to design and develop the anti eavesdropping solutions. In a particular direction, firstly, this paper finds the closed-form expressions of first-order secrecy metrics over multiple input multiple output 2x2 Nakagami-m channel for vehicular networks. The derived closed-form expressions are further utilized to find the upper and lower bounds of secrecy outage probability, and outage probability using the integral bound method for CVN. The derived bound provides the knowledge of the region over a valid signal-to-noise ratio for which the maximum and minimum achievable performance can exist. To restrict the amount of eavesdropping, the convex optimization-based approach is proposed. The optimization method helps secrecy metrics to remain in a specific region of the value. Therefore, the work provides insights over the classical approach and the information-theoretic approach. These works enhance the knowledge to prepare the anti-eavesdropping methods for connected cars. Moreover, the derived analytical expressions demonstrate the impact of the wireless medium on secrecy performance while the derived bound demonstrates the impact of the magnitude of wireless fading parameters.
An Optical Combination Method for Resolving Axial and Transverse Force Interference Using Tapered Fiber Bragg Grating
Authors: ABUSHAGUR ABDULFATAH ABUSHAGUR GHAITH , Bakar Ahmad Ashrif , Arsad Norhana
Published: March 2022

Crosstalk noise between the two force components
(axial and transverse) and temperature is always present when the fibre Bragg
grating (FBG) sensor technology is utilized in many sophisticated equipment. To
address this, we proposed a theoretical method that decouples the two force
components while eliminating the effect of temperature, using a combination of
modified FBGs and a bandwidth modulation mechanism. Our previous study showed
the first step in our continuous effort to prove the concept. In this study,
the second part of proving the decoupling approach while avoiding the
temperature effect is proved experimentally. In addition to the tapered FBG
(TFBG) in its neutral axis, a hollow shaft prototype that resembles the
construction of several medical surgery equipment is being developed further to
include a linear chirped FBG (CFBG) along its shaft's surface. The experimental
results demonstrate that the estimated axial and transverse force values are
consistent with their actual values, with RMS errors of less than 0.32 N and
less than 0.16 N, respectively, over the range of (0 N – 10 N). The presented
method can potentially be extended to small surgical instruments such as
ophthalmia’s needle and ablation catheter.

Published: March 2022

We explore compatibility of Ru with Al-Ge eutectic wafer bonding. We first present experiments to check for the presence of Ru ternary alloy poisoning inhibiting Al-Ge melting as well as evaluations of Al-Ge melt wettability on Ru and diffusion outcomes following bond-simulating anneals. Results show that Ru is stable with no observed microstructural changes or dissolution in the melt, indicating no ternary poisoning for the applied thermal budget. Ru was found to act as an effective barrier offering good melt wettability in all considered configurations with Al and Ge. From inspection of the binary constituents of Al-Ge-Ru we propose that Al-Ge eutectic melting temperature will decrease marginally for Ru contamination in a 1-2% range before a drastic increase in melting temperature (>10°C/% Ru) at higher Ru compositions. We then demonstrate wafer-level packaged 200 mm devices and MEMS with strong bond outcomes of devices bearing Ru contacts. We conclude that Ru has high compatibility with Al-Ge eutectic bonding.
Single Carrier Modulation Resource Allocation for Massive MIMO with Virtual Antennas
Authors: Kenney Brent , Majid Arslan , Moradi Hussein , Farhang-Boroujeny Behrouz
Published: March 2022

Today's Massive MIMO cellular operation is dominated by orthogonal frequency division multiplexing (OFDM) modulation. One of the advantages of OFDM is the flexibility to carve up the available spectrum into resource blocks (RBs) that can operate adjacent to one another.  Massive MIMO adds spatial multiplexing layers on top of the RBs, enabling the simultaneous operation of dozens of UEs.  Cyclic prefixed single carrier modulation (CP-SCM) is an alternative to OFDM that also benefits from massive MIMO and is useful as an OFDM alternative in specific scenarios.  However, until recently, no resource allocation method has been proposed for CP-SCM.  In this paper, we present a CP-SCM resource allocation scheme using virtual antennas in a massive MIMO time domain duplexed scenario.  By creating several virtual antennas for each physical antenna, the benefits of massive MIMO are achieved with a smaller physical antenna count.  Resources are quantized into data streams, and each user can be assigned a variable number of simultaneous streams.  This paper presents a detailed development and analysis of multi-stream processing (MSP) for both uplink detection and downlink precoding.  We also introduce heterogeneous MSP, where CP-SCM and OFDM signals can be processed in the same MSP framework.

ERDHEIM CHESTER disease (ECD) called also non-Langerhans Histiocytosis, is a rare illness, which can present various unusual clinical aspects. It is a Histiocytosis characterized by an infiltration of various tissues and organs, bones, retroperitoneum, pleuro-pulmonary sites, skin, and central nervous system. The most frequent central nervous system manifestations of ECD are diabetes insipidus, cerebellar syndromes, orbital lesions, and extra-axial masses involving the dura and here we report a rare case with spinal cord compression on the context of ERDHEIM CHESTER disease. Our work highlights another different clinical, radiological and pathological manifestation associated with ECD that should be considered.
Dry Eyes and Glaucoma: A Report of Sixty Eyes
Authors: Mohcine El mhadi , Meryem Boughanim , Aziz El ouafi , Said Iferkhass
Published: March 2022

Introduction: Glaucoma is an optic neuropathy defined by optic disc cupping, characteristic visual field defects, and often an increase in intraocular pressure. It remains a leading cause of irreversible blindness, with an estimated 60.5 million people affected worldwide. It is a chronic disease that frequently requires long-term treatment with topical ocular hypotensive eyedrops. The use of antiglaucoma medications has been associated with dry eye. Another reason for the correlation between glaucoma and dry eyes, is that prevalence for both increases with age. Patients and methods: Sixty eyes of 30 patients with medically treated primary open-angle glaucoma (POAG) were included in this study. Dry eye syndrome was searched with Schirmer test (less than 10 mm in 5 minutes) and tear break-up time (BUT: less than 10 seconds). Results: Forty-eight eyes medically treated primary open-angle glaucoma (80%) present dry eye syndrome, this is consistent with previously published literature. All the POAG patients with dry eyes, were medically treated with preserved glaucoma eye drop. They were compliant to their treatment, thinking their vision is blurry because their glaucoma is getting worse and they’re dealing with what they think is irreversible. After solving the dry eye syndrome, we effect a control of the Visual Field test, we can say that dry eye’s treatment can significantly improve reliability and visual field index of glaucoma patients undergoing visual field examination. Conclusion: this study shows that dry eye syndrome associated with glaucoma might lead to ocular discomfort and low-quality retinal images which can decreased compliance of treatment, and deteriorate the Visual field test results. Protecting the integrity of the ocular surface while treating ocular conditions like glaucoma is necessary.

Published: March 2022

Background: Primitive neuroectodermal tumors (PNETs) are highly malignant neoplasms arise from neuroectodermal cells that have cholinergic features. These tumours are closely related to osseous or extraosseous Ewing’s sarcomas, with which they share the same chromosomal abnormality. Over the last few years, PNETs have been increasingly reported to occur in various organs, which may be due to recent progress in immunohistochemical techniques. PNETs arising in the urinary bladder are extremely rare, but more frequent in older adults. Case presentation: A 16 years Moroccan men old, who consults for a total hematuria and dysuria evolving for 2 months in a context of deterioration of the general state. Cyst biopsy was performed. The morphological result in favor of an undifferentiated round cell tumor process infiltrating the bladder muscle, the immu-histochemical study was in favor of a round cell tumor of the Ewing sarcoma/PNET type. Pelvic Magnetic resonance imaging MRI revealed the presence of an endovesical process invading the left antero-inferior pre-vesical fat. We decided, after a multidisciplinary consultation meeting, to start with two cycles of neoadjuvant chemotherapy, then to propose locoregional treatment, either radiotherapy or partial resection. The patient was put on the VAC/IE protocol with a clear regression in tumor size after two cycles. Conclusion: Both clinician and pathologist must be aware of this rare entity during diagnosis and management. Surgery or radiotherapy supported with chemotherapy should be considered an option, especially in advanced disease. Studies of more cases of primary PNET of the urinary bladder with longer follow-up periods are needed to clarify the clinical features and treatment.

Background: Neuroendocrine neoplasms (NENs) are rare tumors .They are defined by the expression of specific biomarkers. Progress in pathological diagnosis has allowed a better identification and classification of these tumors. The 2019-revised World Health Organization (WHO) classification of tumors of endocrine organs classifies grade 3 gastroenteropancreatic neuroendocrine neoplasm (GEP-NENs) into well-differentiated neuroendocrine tumors (NET G3) and poorly differentiated neuroendocrine carcinomas (NEC G3). There are few reported cases of NET G3 occurring in the stomach. Case presentation: A 63-year- man who suffers from dysphagia and Melaena. Fibroscopy revealed a ulcero-budding process of the cardia. Pathologic examination concluded on NET well-differentiated grade 3. Surgical exploration showed peritoneal carcinomatosis and histologically confirmed liver metastases. He underwent chemotherapy with modified folfox 4 protocol for 3 months with satisfactory clinico-morphological response. Conclusion: A definite diagnosis of NET G3 or NEC G3 must be made to determine the appropriate treatment strategy for patients with GEP-NEN G3. the efficacy of treatments for G3 NETs appear modest, as evidenced by the short PFS observed, therefore, more effective therapies are needed with Further case reports and case series. Keywords: Neuroendocrine tumor G3, stomach, modified FOLFOX 4.

Published: March 2022

Background: The role of serum uric acid (SUA) levels as an independent risk factor for vascular disease has been questioned for decades. Epidemiological evidence shows that greater SUA levels may predict an increased risk of cardiovascular (CV) events, such as Stroke. Hyperuricemia has long been linked to cardiovascular illness, hypertension, metabolic syndrome, and kidney disease. Material and Methods: The study was conducted at Dhaka Medical College Hospital from July 2010 to December 2010. This study included one hundred first-time stroke patients, both male, and female (non-pregnant), who fulfill the inclusion criteria. It was a prospective observational study. A purposive sampling technique was used. Fifty-nine percent of the patients were male, and the rests were female. About 85% of them were Muslim. Result: The mean age of the patients was 62.3 years with an SD ± 9.078 years. Patients from the age group 51-60 years formed the main bulk, followed by 61-70 years group (36% and 33% respectively). The mean value of serum uric acid was found as 7.108 mg/dl (SD ± 2.292), which was clearly above the normal limit. The mean value of Random Blood Sugar was 7.45 mg/dl with SD ± 3.292 (n=86), and for Serum Creatinine, the mean and SD value were 0.898 and 0.2108, respectively, which are within the normal limit. Lipid profiles were checked in 93 patients. It was shown that the Cholesterol level was much higher than the normal value, but other parameters were somewhat normal and about half of the male respondents were hypertensive. The prevalence of hypertension in females was little more than their male counterparts. The study revealed that about 24% of all male stroke patients suffered from DM, whereas females were 17%. This difference was not statistically significant. Conclusion: Right-sided hemorrhagic CVD topped the tally in both sexes, followed by left-sided hemorrhagic CVD. The prevalence of Ischemic CVD was found to be a little lower. The present study ...........

Purpose: To compare the results of pupil dilation by an intracameral injection of preservative free 1% lidocaine with conventional topical mydriatics during phacoemulsification cataract surgery. Comparison was also done for simultaneous anaesthetic effect between intracameral lidocaine and topical mydriatics. Methods: A randomized, comparative interventional study was conducted. The study included 50 patients who underwent phacoemulsification and intraocular lens implantation surgery and were divided in two groups. One group was given topical mydriatics (25 eyes) preoperatively and other intracameral lidocaine (25 eyes) at commencement of surgery to dilate the pupil. The topical group received 3 drops of tropicamide 0.8% and phenylephrine 5% eye drops 15 minutes apart starting 45 minutes before surgery. The intracameral group received preservative-free lidocaine 1% (0.2 to 0.3 mL) injected just before the procedure began. In both groups, the horizontal pupil diameter was measured before and after pupil dilation using the same caliper. Total surgical time, need for a supplement mydriatic agent during the surgery and subjective surgical performance were recorded. Any adverse ocular and systemic effects between two groups were also compared. Results: The mean age, sex, cataract grading, baseline horizontal pupil diameter and mean surgerical time were similar between the topical and intracameral group. The mean pupil dilation was 4.62 ± 0.96 mm in the intracameral group and 4.76 ± 0.75 mm in the topical group. There was no statistically significant difference between the two groups (P value =0.57).There was no significant difference between groups in the overall subjective surgical performance (P=0.72). No patient in any group required supplementary intracameral mydriatic injection. Conclusion: Intracameral lidocaine is a safe, effective and reliable alternative to topical mydriatic for pupil dilation with added advantages of fast postoperative recovery and is also ....

Authors: Saisudha Dr. Domakonda , Vivekanand Dr. N. , Naseer Dr. Masrath
Published: March 2022

Introduction: Blood donor deferral means that an individual is not eligible to donate blood or blood components based on the criteria used to protect the health and safety of both donors and transfusion recipient. A prospective donor may be deferred at any point during the collection and testing process. This step is important in ensuring safe transfusion practices to the recipients and the health of the donor, This is a study to categorise the deferrals according to the reasons and to delineate the causes for deferral among the whole blood donors. Methodology: This was a descriptive cross sectional study performed at Department of transfusion medicine at Kamineni academy of medical sciences and research centre at LB nagar, Hyderabad .This study was performed from January 2018 to December 2020. The various reasons for deferral of the whole blood donors from the donations were collected from the donor deferral registry. Results: The donor deferral rates for the years 2018, 2019, 2020 were 8.3%, 7.9% and 4.3% respectively, out of the total donations the highest deferral rate was among the female population the common reason being anemia, the other causes for deferral being alcohol consumption and tattooing and medical causes. Conclusion: We observe from this study that the maximum number of deferrals among the female population were and the cause is preexisting anemia, it is important to advice and counsel the donors before the blood donation to avoid adverse reactions among the donors as well as the recipients, awareness programs and donor motivation programs must be implemented.

Published: March 2022

Background: It has long been recognized that blood bank institutions have an obligation to not only provide a safe product for patients, but also to protect the health and welfare of their donors and their staff. Quality control procedures are indispensable to en¬sure the reliability of the results provided by labora¬tories responsible for serological screening in blood banks. International recommendations on systems of quality management classify as a top component the inclusion of two types of control: (a) internal quality control (IQC) and (b) external quality control (EQC). Methods: A total of 300 donations were collected and screened for HBV, HCV, syphilis and HIV-1 using the enzyme inked immune sorbent assay. All initially reactive (IR) samples were retested in triplicate and, if repeatedly reactive (RR), consider as reactive. Results: The results showed that the sensitivity and specificity of the QCs in anti-B testing were 100% and 98.7%, respectively. The sensitivity and specificity of the QCs in testing, viral screening were all 99%. Therefore our QC products and methods are highly sensitive, specific, and reliable. Our study paves the way for the establishment of a uniform and standardized QC method for pre-transfusion compatibility testing in Sudan and other parts of the world. Conclusion: The implementation of screening for three viruses has improved blood safety in Sudan.

Penerapan PPh Pasal 23 Atas Jasa Boga Oleh Puskesmas Gondang Serta Prosedur Pemindahbukuan Pajak Karena Kesalahan Saat Penyetoran
Authors: Elsa Alfa Maharani Yhola  , Rifki Firdaus Sukma
Published: March 2022

AbstractThe research was carried out to see the application of the calculation and payment of Article 23 Income Tax for Catering Services implemented by the Gondang Health Center, also aimed at knowing the tax book-entry procedure due to an error when depositing or paying taxes. This research uses an internal secondary data analysis method, because the main focus comes from real data on tax payments by the Gondang Health Center. In addition, the researchers also applied short interviews and observations, both participant and non-participant observations were used because they were considered to produce more accurate, complete and timely data. Based on research, Gondang Health Center has calculated and paid Article 23 Income Tax properly and in an orderly manner, but has never inputted withholding evidence in the e-Bupot PPh 23 application on the website of the Directorate General of Taxes. This means that the Treasurer of the Gondang Health Center still has the task of learning how to input cut evidence in e-Bupot in order to prove accountability for the orderly implementation of tax obligations on the collection of the catering service tax that is subject to Article 23 Income Tax.

Abstrak

Penelitian dilaksanakan untuk melihat penerapan dalam penghitungan dan pembayaran PPh Pasal 23 atas Jasa Boga yang diterapkan oleh Puskesmas Gondang, juga bertujuan untuk mengetahui prosedur pemindahbukuan pajak karena kesalahan saat penyetoran atau pembayaran pajak. Penelitian ini menggunakan metode analisis data sekunder internal, karena fokus utamanya bersumber dari data riil penyetoran pajak oleh Puskesmas Gondang. Di samping itu, peneliti juga menerapkan wawanacara singkat dan observasi, baik observasi partisipan maupun observasi non-partisipan digunakan karena dianggap akan menghasilkan data yang lebih akurat, lengkap dan tepat waktu. Berdasarkan penelitian, Puskesmas Gondang telah melakukan penghitungandan pembayaran Pajak Penghasilan Pasal 23 dengan baik dan tertib, namun belum pernah melakukan input bukti potong dalam aplikasi e-Bupot PPh 23 di laman milik Direktorat Jendral Pajak. Hal ini berarti Bendahara Puskesmas Gondang masih memiliki tugas untuk belajar cara input bukti potong dalam e-Bupot demi membuktikan akuntabilitas atas tertibnya pelaksanaan kewajiban perpajakan atas pemungutan pajak jasa boga yang dikenakan PPh Pasal 23.
On Multisets, Interpolated Multiple Zeta Values and Limit Laws
Authors: Kuba Markus
Published: March 2022

In this work we discuss a parameter $\sigma$ on weighted $k$-element multisets of $[n]= \{1,\dots ,n\}$. The sums of weighted $k$-multisets are related to $k$-subsets, $k$-multisets, as well as special instances of truncated interpolated multiple zeta values. We study properties of this parameter using symbolic combinatorics. We (re)derive and extend certain identities for $\zeta^{t}_n(\{m\}_k)$. Moreover, we introduce random variables on the $k$-element multisets and derive their distributions, as well as limit laws for $k$ or $n$ tending to infinity.
Snarks with Resistance $n$ and Flow Resistance $2n$

We examine the relationship between two measures of uncolourability of cubic graphs – their resistance and flow resistance. The resistance of a cubic graph $G$, denoted by $r(G)$, is the minimum number of edges whose removal results in a 3-edge-colourable graph. The flow resistance of $G$, denoted by $r_f(G)$, is the minimum number of zeroes in a 4-flow on $G$. Fiol et al. [Electron. J. Combin. 25 (2018), $\#$P4.54] made a conjecture that $r_f(G) \leq r(G)$ for every cubic graph $G$. We disprove this conjecture by presenting a family of cubic graphs $G_n$ of order $34n$, where $n \geq 3$, with resistance $n$ and flow resistance $2n$. For $n\ge 5$ these graphs are nontrivial snarks.
Polyester materials for mRNA delivery

Published: March 2022

Messenger RNA (mRNA) has recently made important progress in clinical implementation, offering a promising therapeutic option for infectious disease and cancer. However, the nature of mRNA molecules rendered them poorly bioavailable and unstable in vivo, impeding their further clinical application. Therefore, safe and efficient delivery of mRNA therapeutics to the target site is crucial for their successful translation into the clinical setting. Various vectors have been explored for mRNA delivery. Among them, polyesters and their analogs, a family of biodegradable polymers, have exhibited great potential for mRNA delivery. In this short review, the authors briefly introduce mRNA therapeutics, their therapeutic applications and delivery challenges. The authors then presented the typical examples of polyester materials for mRNA delivery to highlight the current progress and discuss the challenges for the rational design of polyester based mRNA delivery vectors. The authors hope to provide a new insight for the design of biodegradable vectors for nucleic acids delivery, thereby promoting their further clinic translation.
