Behçet’s disease (BD) is a multi-systemic vasculitis characterized by attacks of acute inflammation, which can affect multiple area of the body. Neurological involvement known as “neuro-Behcet’s” (NB) is rare and is one of the main causes of long-term morbidity and mortality. The aim of our work was to study the epidemiological, clinical, paraclinical and therapeutic characteristics of patients with BD with neurological involvement. We conducted a retrospective study of NB patients in the Neurology and Internal Medicine departments of the Military Instruction Hospital of Tunis. We collected 35 patients from a population of 150 patients with BD. Neurological manifestations had inaugurated the BD in 55% of the cases. Ninety-four percent of patients had central nervous system involvement and 6% had peripheral polyradiculoneuritis. Parenchymal involvement occurred in 85% of cases and non-parenchymal NB in 3% of cases. Brain magnetic resonance imaging (MRI) showed predominant demyelinating lesions in periventricular and brain stem in 15 patients, a pseudotumor appearance in 3 patients, and vascular lesions in 2 patients. All patients received corticosteroid and 30 patients were treated with immunosuppressive therapy. Three patients had received an immunomodulatory treatment by anti- TNF alpha. The outcome was unfavorable in patients with diffuse disease, brain stem damage, spinal cord injury, polyradiculoneuropathy and mixed impairment. Neurological manifestations of BD are various and are typically of poor outcomes with a high mortality and heavy sequelae. The prognosis depends on parenchymal involvement and time to initiate treatment.

Published: April 2024

Background: The underlying bone framework always determines the soft tissue contours. Numerous aetiologies are linked to tooth loss, which frequently causes abnormalities of the alveolar ridge. Alveolar bone changes in volume as a result of physiologic bone remodelling after tooth extraction, which impacts the way how edentulous area is treated with prosthetic rehabilitation. By limiting the natural post-extraction resorption process, socket preservation methods following tooth extraction will lessen the need for additional ridge augmentation techniques before implant placement while maintaining the existing bone. Case Report: Two male patients, ages 36 and 32, were referred for the extraction of their severely deteriorated first molars in the mandible and for the placement of dental implants to restore the area. Patients were identified as having periodontitis and root caries respectively. In one example, the socket was promptly grafted with Platelet Rich Fibrin with xenograft, and in the other with a collagen sponge, after the irreparable tooth was “atraumatically” excised without creating a flap. After suturing the region, a periodontal dressing was applied and no membrane was employed. Conclusion: After six months, the ridge’s architecture was preserved, and clinical examination showed outstanding soft tissue healing. At six months, a clinical and radiological follow-up evaluation demonstrated consistent and positive outcomes. This article discusses and emphasises the significance of socket preservation after tooth extraction utilising different biomaterials in different case scenarios.

Biomarkers are measurable indicators of a biological state or condition. In the context of COVID-19, biomarkers can be used to diagnose the disease, monitor its progression, and evaluate the effectiveness of treatments. One common biomarker for COVID-19 is the presence of viral RNA in a patient’s respiratory samples, as detected by Reverse Transcription Polymerase Chain Reaction (RT-PCR) tests. Antibody tests, which detect antibodies against the SARS-CoV-2 virus in a patient’s blood, can also be used as biomarkers, although they may not be as reliable in the early stages of infection. Other biomarkers that have been studied in the context of COVID-19 include proinflammatory cytokines, such as interleukin-6 (IL-6), which are known to be elevated in patients with severe disease. There are also several biomarkers being studied for their potential use as indicators of disease severity or risk of progression to severe disease. It’s important to note that biomarkers are changing rapidly as more research is being done on COVID-19, and new biomarkers are being discovered and characterized.
Using the Gut Antigen HA86 as a Biomarker for Hyalomma Tick Bites, the Principal Vectors of the Crimean-Congo Hemorrhagic Fever Virus
Authors:   Department of Virology, Institut Pasteur de Dakar, Dakar 12900, Senegal, Mhamadi Moufid
Published: April 2024

Hyalomma ticks are the principal vectors of the Crimean-Congo hemorrhagic fever virus. Antibody responses and the viral genome, are usually used for virus surveys. These markers cannot assess the role of ticks in the burden of CCHFV. It has been documented that tick bites induce a host immunological response, and numerous antigens have been described. To note, the gut protein Bm86 of Boophilus micropulus induces such an immune response, and several orthologues have been identified. Furthermore, a cross-immunological response against orthologues was reported. Based on these findings, we hypothesized that the Bm86 of Hyalomma ticks could serve as a biomarker of exposure to Hyalomma tick bites. For this purpose, 2432 ticks, 435 human and 480 animal sera, collected in Agnam (Northern Senegal) between February 2021 and April 2022 for arbovirus and viral hemorrhagic fever surveys were used. We found that the development of HA86 IgG in livestock sheep is influenced by exposure to Hyalomma ticks. Additionally, the anti-HA86 antibodies did not persist for more than 2 months, and no cross-HA86 response wasn’t detected between Hyalomma and Rhipicephalus species. These results suggest that HA86, could be used as a biomarker for Hyalomma tick bites.

Antibiotics are secondary metabolites produced by micro-organisms which act against other organisms. The producing organisms are protected from its harm by various methods. These are life-saving miracle drugs which are used not only for human diseases but also as growth promoters in animal husbandry, agriculture, food processing etc. This has made bacteria resistant to these miracle drugs which has hampered human health especially the high-risk patients like immune-compromised, organ transplants, HIV or even Corona infected patients causing increase in fatality rates. To put in the words of Johusa Lederberg “Antibiotic resistance as a phenomenon is, in itself, not surprising. Nor is it new. It is, however, newly worrying, because it is accumulating and accelerating, while the world’s tools for combating it decrease in power”. Therefore, now the time has come to decide between more trade and human life. The review discusses these aspects along with different ways which has increased drug resistance.

Published: April 2024

This seminar paper reviews reproduction and production performance of one–humped camels. Camels are strongly tolerant to punitive and more hostile climatical and environmental determinants unlike most other animals. They are defined to be ship of desert particularly dromedarian camel. There are three main species, even though there is some controversial, namely C. bacterian, C. one-humped (dromedarian) and C. ferus. They get full maturity at the age range of 3 to 5 years old. Rutting is a special sign for that the bull reached full maturity, it develops a very unique feature that is the dulla (a soft and balloon like tissue that develops in oral cavity during peak maturity). In case of female, it can give first birth at age of 5 years old usually with a single calf which means very rare twining. Camel is mainly kept for milk production, which valuable for human food in the arid environment of camel keeping countries. Camel has the ability to produce milk of good composition and quantity for human consumption even when water is severely restricted. Milk is the main sources of nutrition for pastoralists, neonates calves and provides all essential nutrients for growth and development, e.g. proteins, minerals, carbohydrates, fatty acids, growth factors, immune modulators, etc Camels have high milk yield and comparatively long milk service period for both their calves and human. Additionally, they highly prefer to consume halophilic plants such as Atriplex which is believed to qualify more the milk. Despite from milk, camels also provide meat as well as hides.

Problems and prospects in forecasting the stocks of pacific salmon in Khabarovsk Region
Authors: Ostrovsky V. I.
Published: April 2024

Methods for forecasting the stocks of pacific salmon in Khabarovsk Region are considered. Errors of the forecasts based on theoretical parent-offspring models are associated with variability in weather conditions on the spawning grounds. The progeny dynamics is modeled much better when weather factors are assimilated into the single- factor models. The errors reduction would be expected for multifactor models, assuming that they will be based on reliable data on the number of parents and offspring, though this condition seems questionable in the face of a growing shortage of qualified observers and modelers.

Trawl surveys on juvenile pink salmon in fall season provide crucial information for forecasting their returns because of lower mortality of the juveniles in this season compared to their mortality during downstream migration in rivers or in the early marine period. Surveys by two research vessels give an opportunity to cover vast are- as in a short time and to exclude repeated counts of actively migrating fish on adjacent transects. The surveys in the Bering and Okhotsk Seas in the fall of 2023 were well planned and done, so the main aggregations of pink salmon in the offshore areas were assessed, ensuring good reliability of the data on this species abundance used for forecasting pink salmon adults returns and catch. Two regional groupings of juvenile pink salmon in the Okhotsk Sea were differentiated in mixed catches using the EM clustering method; the ratio of the «northern» and «southern» groupings was 40:60%. The total counted abundance of juvenile pink salmon was 0.33.109 ind. in the Bering Sea and 1.40.109 ind. in the Okhotsk Sea that allowed to expect preliminary the returns of approximately 100.106 ind. to the Bering Sea rivers and 208.106 ind. to the Okhotsk Sea rivers in 2024.

La pandemia declarada de manera global por la COVID-19 ha alterado varias de las dinámicas del mundo académico. En su comienzo se pensaba, con fundamento en el desarrollo tecno científico alcanzado por la humanidad, que la pandemia era un asunto que se resolvería en poco tiempo; por lo que muchas instituciones educativas simplemente optaron por cerrar el acceso a sus campus y esperar su resolución. Es más, incluso tras los aislamientos obligatorios, algunos campus continuaron cerrados para docentes y estudiantes. Como consecuencia se forzó la enseñanza virtual sin tener, en todos los casos, la preparación e infraestructura necesarias.

The results of real-time observations of the oxidation-reduction potential (ORP) in groundwater from two wells in the Kultuk area from December 2023 to March 2024 are presented. Variations of this parameter show reorganizations, accompanied by short episodes of single earthquakes and longer intervals of earthquake series in the central part of the Baikal Rift System. A change from low to high ORP values accompanies the general transition from strong to weak earthquakes. The uneven variations in ORP of the monitoring stations are suggested to associate with piezoelectric effects that arise when seismic waves act on quartz of the ordered tectonite structures in different active structures of the South Baikal basin: in its marginal Obruchev fault and in the axial Kultuk tectonic step.

Real-time groundwater monitoring on a shore of Lake Baikal reveals peculiar effects in the form of quasi-periodic negative ORP pulses with varying time intervals and a decrease in ORP relative to the background during the week of February 2024. We perform an express analysis of the observed effects and pay attention to their occurrence during increasing air temperature. At the beginning of the observation interval, we determine the regime of initial ORP pulses, which occur in conditions of a slightly increasing air temperature, then the middle one in a conventionally-optimal regime in conditions of significant warming, and the final regime of retrograde evolution in cooling conditions. The revealed regularities in changes of pauses between pulses and amplitudes of ORP reductions relative to the background form the basis for the analysis of ongoing effects.

A review of lunar studies is given that indicate the isotope crisis of the Earth mega-impact hypothesis and the removal of emerging contradictions by a competing model of the origin of the Earth-Moon binary system from a gas-dust cloud. The simultaneous solidification of the magma ocean of the Moon with the solidification of the magma ocean in the global ASITA heterogeneity of the Earth 4.54–4.44 billion years ago is substantiated. From the model of the Earth–Moon binary system, the solidification of the ASITA magma ocean is assumed to precede the solidification of the rest of the Earth. It is concluded that the Earth's crust consolidated at different times after the solidification of the magma ocean: in ASITA – 4.31 billion years ago and in the rest of the Earth – with a delay of up to 3.82 billion years ago.

In an era of Artificial Intelligence (AI), governments around the world are advancing their digital footprints, and using AI to achieving their objectives of effective and efficient public service delivery and citizens engagement. Knowledge Graph (KG), a constituent AI technology, has proven to be the means through which a government can use to manage the complexity of an e-Government instance, and realize its objective. One area in e-Government that KG is used to address, is the challenge of automated composition of web services, where web services are created and maintained by one government department, but is used by another, in an integrated and interoperable manner. Service composition is the combination of two or more web services to create a composite service in order to accomplish a task. In this paper, we present a KG-based approach for automatically composing web services in an e-Government context. Our aim is to advance the e-Government objective of effective and efficient public service delivery and citizens engagement, given a complex e-Government. We focus on creating a Service Dependency Graph (SDG), which captures the semantic relationships between the services, and we further describe the services with QoS characteristics, and then we create a weighted graph based on these two descriptions. We then adapted the Uniform Cost Search algorithm to find the shortest path between a start node and a goal node. We implement our algorithm, and carried-out experiments to obtain execution times, and we compared our results with benchmark results of comparable experimental setup. The difference in execution times of the service composition task is dependent on factors such as the design of the composition model, the complexity of the composition graph, and the hardware and software environments. Our research approach affords us the means to analyze and design our model; and validate and evaluate our work. Our model and the development approach help to achieve the e-Government goals of efficient and effective service delivery and citizens engagement.

Penelitian ini untuk meningkatkan integritas nilai budaya pada peradaban NU dalam membangkitkan Era baru, menganalisis, memahami dan melihat gerakan yang dilakukan NU dalam membangun Era yang unggul serta bentk-bentuk penerapan nilai budaya yang diberikan NU kepada masyarakat khususnya generasi penerus. Kerangka teorii yang digunakan dari Nobert Elias dan F Ratzel. Nobert Elias mendalami kesosialan yaitu struktur sosial, dinamika sosial, dan kebudayaan. F Ratzel menjelaskan pentingnya adanya difusi pada masyarakat. Metode penelitian penulisan ini berupa jenisnya Kualitatif deskritif, dilakukan cara menggambarkan penelitian terkait gerakan NU tanpa menghilangkan unsur nilai budaya pada peradaban ormas. Dan metodenya yaitu narrative research, metode ini digunakan membantu untuk memahami, analisis serta mengevaluasi suatu kisah. Pendekatan yang diterapkan dari August Comte teorinya yaitu dinamika sosial dan statika sosial. Teknik pengumpulan data dilakukan menggunakan dua metode yaitu studi pustaka dan dokumen. Serta analisis data menggunakan beberapa teknik yaitu reduksi data, penyajian data, dan kesimpulan.

Hasil dan pembahasan mengungkapkan bahwa gerakan NU dalam membangkitkan peradaban era baru melahirkan satu kesatuan dengan konsep-konsep disertai dakwah kekhasan yaitu dakwah yang diteruskan oleh para ulama dahulu. Untuk merealisasikan gerakan NU dalam membangkitkan peradaban di Era Baru, ormas harus bergerak sesuai langkah-langkahnya seperti gerakan pemikiran NU terkait penyebaran ajaran Islam (gerakan keagamaan), gerakan politik, bergerak di bidang ekonomi, dan gerakan pada ranah sosial. Penerapan nilai Budaya yang dilakukan NU terhadap era baru. NU menempatan kepercayaan dengan sub-dominan bertujuan agar terdorongnya semua aspek kehidupan masyarakat yang diwarnai dengan ajaran agama, termasuk dorongan sistem kepercayaan yang ikut ikut mengkonverensi kepercayaan dan budaya. Terakhir yaitu dampak positif dan negatif dari pengembangan gerakan NU di era baru, NU berupaya melestarikan nilai-nilai budaya yang menjadi ciri khas organisasi, sehingga nilai budaya yang diterapkan yaitu Islam Nusantara tidak luntur dan hilang di Era Baru. Dampak negatifnya Demi menjaga dan melestarikan nilai budaya NU bergerak maju tanpa penyesuaian dari kelompok aliran agama lainnya, sehingga hal tersebut menjadi ciri khas yang bersangkutan, bahwa NU memiliki nilai kebudayaan yang berbeda dari aliran lainnya. Kesimpulannya NU menerapkan nilai budaya ke dalam integritasnya, berkembang dengan merujuk penninggalan ulama dahulu, hal ini dikarenakan sebagian pemikiran NU merupakan kekayaan identitas dari lembaga. NU memunculkan suatu gerakan berupa strategi dalam menghadapi globalisasi dimasyarakat, dirumuskan dalam bentuk tujuh strategi kebudayaan (saptawikrama) Islam Nusantara.konsep ini lahir saat rakernas PBNU.

Process calculi and the verification of security protocols
Authors: Boreale Michele , Gorla Daniele
Published: April 2024

Recently there has been much interest towards using formal methods in the analysis of security protocols. Some recent approaches take advantage of concepts and techniques from the field of process calculi. Process calculi can be given a formal yet simple semantics, which permits rigorous definitions of such concepts as ``attacker``, ``secrecy`` and ``authentication``. This feature has led to the development of solid reasoning methods and verification techniques, a few of which we outline in this paper.
CAPSL and MuCAPSL
Authors: Millen Jonathan K. , Denker Grit
Published: April 2024

Secure communication generally begins with a~connection establishment phase in which messages are exchanged by client and server protocol software to generate, share, and use secret data or keys. This message exchange is referred to as an authentication or key distribution cryptographic protocol. CAPSL is a formal language for specifying cryptographic protocols. It is also useful for addressing the correctness of the protocols on an abstract level, rather than the strength of the underlying cryptographic algorithms. We outline the design principles of CAPSL and its integrated specification and analysis environment. Protocols for secure group management are essential in applications that are concerned with confidential authenticated communication among coalition members, authenticated group decisions, or the secure administration of group membership and access control. We will also discuss our progress on designing a new extension of CAPSL for multicast protocols, called MuCAPSL.
New approach to computer aided design of coupled resonator filters
Authors: Kozakowski Piotr , Mrozowski Michał
Published: April 2024

A gradient based optimization technique along with a new definition of cost function is applied to synthesis of coupled resonators filters. The cost function is defined using location of zeros and poles of the filter`s transfer function. The topology of the structure is enforced on each step of optimization and its physical dimensions are used as independent variables.
On a method to improve correlation properties of orthogonal polyphase spreading sequences
Authors: Wysocki Beata J.
Published: April 2024

In this paper, we propose a simple but efficient method for improving correlation properties of polyphase spreading sequences for asynchronous direct sequence code division multiple access (DS CDMA) applications. The proposed method can be used to reduce the mean square value of aperiodic crosscorrelation or the mean square value of aperiodic autocorrelation, the maximum value of aperiodic crosscorrelation functions, merit factor or other properties of the sequence set. The important feature of the method is that while it modifies correlation properties of the sequence set, it preserves sequence orthogonality for perfect synchronization, if this is the property of the original sequence set.
Blind frequency offset estimation for overlap PCC-OFDM systems in presence of phase noise
Authors: Shentu Jinwen , Armstrong Jean
Published: April 2024

This paper presents a technique for frequency offset estimation for polynomial cancellation coded orthogonal frequency division multiplexing with symbols overlapped in the time domain (overlap PCC-OFDM) in the presence of phase noise. The frequency offset estimator is designed based on the subcarrier pair imbalance (SPI) caused by frequency offset. The estimation is performed in the frequency domain at the output of the receiver discrete Fourier transform (DFT). No training symbols or pilot tones are required. Simulations show that this estimator is an approximately linear function of frequency offset. Phase noise does not significantly affect the variance performance of the estimator.

Near fields of elliptic dielectric lenses
Authors: Boriskin Artem V. , Marciniak Marian
Published: April 2024

The focusing properties of an elliptic dielectric cylinder taken as a 2D model of dielectric lens are studied for the plane wave illumination. An algorithm based on the concept of analytical regularization is applied for the numerical solution of the corresponding wave scattering problem. Numerical results for the near-field patterns are presented.
The role of time in influence diagrams
Authors: Traczy Wiesław
Published: April 2024

An influence diagram is a compact representation emphasizing the qualitative features of decision problem under uncertainty. Classical influence diagram has parameters stable in time, determined order of suggested decisions and generally is independent of time. Here we have shown some possible methods of construction of time dependent influence diagrams: with decision ordering, time-sliced segments and time consuming nodes. Such gathering of methods can help in selection of a proper solution.
Decision algorithms and flow graphs; a rough set approach
Authors: Pawlak Zdzisław
Published: April 2024

This paper concerns some relationship between Bayes` theorem and rough sets. It is revealed that any decision algorithm satisfies Bayes` theorem, without referring to either prior or posterior probabilities inherently associated with classical Bayesian methodology. This leads to a new simple form of this theorem, which results in new algorithms and applications. Besides, it is shown that with every decision algorithm a flow graph can be associated. Bayes` theorem can be viewed as a flow conservation rule of information flow in the graph. Moreover, to every flow graph the Euclidean space can be assigned. Points of the space represent decisions specified by the decision algorithm, and distance between points depicts distance between decisions in the decision algorithm.
Weight versus reference point multiple criteria decision making methods - analogies and differences
Authors: Kaliszewski Ignacy
Published: April 2024

In this work we shall be concerned with interactive multiple criteria decision making methods. We show how on the technical level the class of reference point methods can be reduced to the class of weight methods. Though methods from these two classes represent two different interactive decision making paradigms, the equivalence observed opens a way for a joint implementation of a pair of methods each representing a different class. This would establish a firm ground for systematic comparison of both classes of methods as well as for hybrid schemes mixing decisional tools specific for each class.

Authors: Jarmakiewicz Jacek , Bednarczyk Mariusz , Krygier Jarosław
Published: April 2024

The IPSec protocols architecture that can be applied in tactical Intranet based on the IPv6 protocol stack for wireless environment is the subject of the paper. The potential usefulness of the new version of IP protocol is very important for tactical communication systems. Additionally, Internet Engineering Task Force (IETF) security working group proposes recommendations covering the RFC 2401, 2402, 2406, that describe the security architecture for Internet Protocol. These standards, published by IETF are discussed here in military requirements context. The NATO~C3 Technical mbox{Architecture} model also recommends these issues. The concept of the IPSec architecture in military systems is described in the paper. The position of the security applications designed for subscriber devices with reference to layered model is also presented. The concept presented here is defined for the tactical level.

Use of Cannabis for Medical or Recreational Purposes Among US Young Adults: Correlates and Implications for Problematic Use and Interest in Quitting
Authors: Sridharan Priyanka , Romm Katelyn , Berg Carla
Published: April 2024

Objective: Recreational and medical cannabis use has increased, particularly among young adults, but little is known regarding who uses for these purposes or how purpose of use is associated with problematic use. Method: We analyzed Fall 2019 survey data among 1,083 US young adults (ages 18-34) reporting past 6-month cannabis use. Multivariable regression analyses examined: 1) characteristics of those using for only/primarily medical purposes, primarily recreationally, and only recreationally vs. equally for medical and recreational purposes (referent; multinomial logistic); and 2) reasons for use in relation to cannabis use disorder symptoms (linear) and driving under the influence of cannabis (DUIC; binary logistic). Results: 37.1% used only recreationally, 23.5% primarily recreationally, 21.5% equally for both, and 17.8% medically. Compared to those using equally for medical and recreational purposes, those using only/primarily medically had fewer friends who used cannabis; those using primarily recreationally were younger, more educated, less likely used tobacco, and reported fewer ACEs. Those using only recreationally were younger, more likely male, less likely to report an ADHD diagnosis or past-month alcohol or tobacco use, and reported fewer friends who used cannabis, ACEs, and depressive symptoms. Using equally for medical and recreational purposes (vs. all other cannabis use subgroups) correlated with greater use disorder symptoms and DUIC. Conclusions: Using cannabis equally for medical and recreational purposes may pose particularly high-risk, given the association with greater mental health concerns and problematic use. Understanding use profiles and how young adults interpret and distinguish medical and recreational use is critical.
