Abstract:

Background. The transport layer is designed to deliver data without errors, losses and duplication in the order in which they were transmitted. It provides data transfer between two applications with the required level of reliability. Transport layer protocols, which guarantee reliable data delivery, establish a virtual connection before data exchange and resend segments in case of loss or damage. The aim of the study was to determine the role of transport security protocols in computer networks. Materials and methods.

Abstract:

The paper discusses models and methods for improving the performance of wireless computer networks built based on the decomposition of the lower levels of the OSI reference model. A method to improve the performance of networks is suggested, which functionally combines the physical and network layers, which improves its efficiency in marginal reception areas almost twice. A model of the block diagram of a device for improving data transmission quality in marginal reception areas or those with insufficient noise immunity is developed based on the so-called communication quality status monitorin

Abstract- The increasing complexity of modern vehicles necessitates the use of multiple Electronics Control Units (ECUs) to manage and monitor various functions.

To address this, standardized diagnostic protocols such as On-Board Diagnostics (OBD2) have been developed, providing a comprehensive framework for fault detection and in-vehicle communication.

Abstract:

The structure of the ISO/OSI model does not allow choosing the optimal packet transmission route at the channel level and preventing the formation of ring routes. These functions are performed by the network layer. In general, the problem of packet routing is solved by the switch based on the routing algorithm, which contains a hidden "flooding" mechanism. A packet from the sender's switch is sent to all ports, except for the port where the packet was received. When a packet arrives, the switch analyzes the header and if the address in the header matches the address to which the switch belongs

These patients also have not responded well to new therapies under development, including BTK inhibitors (Wilson et al, Blood 2012; 120). The MYD88 L265P oncogenic mutation has been shown to over-activate TLR7- and TLR9-mediated signaling pathways, including NF-κB, IRAK1/4 and STAT3, which in turn promote cell survival and proliferation (Lim et al., AACR 2013, Abstract #2332).

Abstract:

Geothermal resources (e.g. hot springs) are found with the help of field techniques, such as geological, geochemistry and geophysical. These techniques in some occasions are difficult to apply because of the limit access to the research area, rising operational costs and constrained spatially the exploration areas. The thermal infrared (TIR) remote sensing is an important tool for the exploration of geothermal resources, due to the low cost and high efficiency in the study of large geographic areas. The aim of this study is to use thermal imagery of satellite remote sensing and combined with g

Abstract:

Background:The improvement of the existing diagnostic methods to detect pre-radiographic knee OA (KOA) may facilitate the development of preventive strategies. It has been postulated that combining biochemical with clinical markers, may increase the prognostic power to detect who is at high risk for developing KOA.Objectives:To validate and qualify the ability of 6 proteins with biomarker potential to generate a prognostic model of knee OA prediction through the combination of validated OA biomarkers and clinical markers.Methods:In thevalidation phase(Figure 1), 749 sera at the baseline visit

Abstract:

Abstract Purpose: All patients with metastatic breast cancer (BC) expressing estrogen receptor α (ESR1) will eventually develop resistance to endocrine therapies. In up to 40% of cases, this resistance is caused by activating mutations in the ligand-binding domain (LBD) of ESR1. Clinical evidence suggests adverse outcomes for these patients. Our hypothesis was that ESR1 mutations may confer resistance to subsequent treatment lines, specifically chemotherapy. Experimental Design: MCF-7 cells harboring ESR1 mutations (Y537S and D538G) were used to characterize proliferation, apoptosis, and tumor

Technologiczne przedsiębiorstwa typu start-up przyczyniają się do napędzania światowej gospodarki oraz przedsiębiorczości. Pomimo swojej elastyczności oraz relatywnie niskich kosztów wejścia na rynek, jednym z głównych problemów dotyczących rozwoju start-upów jest kwestia finansowania. Start-upy nie wpisują się w tradycyjną konwencję finansowania przedsiębiorstwa głównie dlatego, że są to przedsięwzięcia o względnie dużym poziomie niepewności co do ich pr

Abstract:

The penetration of ICT in the management and study of material culture and the emergence of digital cultural repositories and linked cultural data in particular are expected to enable new paths in humanities research and new approaches to cultural heritage. Success is contingent upon securing information trustworthiness, long-term preservation, and the ability to re-use, re-combine and re-interpret digital content. In this perspective, we review the use in the cultural heritage domain of digital curation and curation-aware repository systems; achieving semantic interoperability through ontolog

Abstract:

In this article the network security mechanisms used by host layers and the network layer of the OSI model are discussed. Many years ago, the existence of intruders was not established, therefore the security protocols of these layers were designed accordingly. But in present times, these protocols may not hold  much significance. Therefore it is needed that we either change them, or enhance them further. There are only few instructions available for secure programming and we have almost negligible resources for secure

In this paper, I review the role of OSI-Model. This paper examines the problem of cybersecurity threats that are implemented on networks . OSI-Model is a 7 layer architecture with each layer having specific functionality to perform. All these 7 layers work collaboratively to transmit the data from one person to another all around the world. networks as being structured in the seven layers of the ISO-OSI model, it makes sense that cybersecurity threats can happen at any layer. We can think of these layers as the "links" in our metaphorical chain. Moving outward from the user, data is

In case of digital planning, it can be taken over from the planning and the appliance can be produced in advance. This study aimed to evaluate the accuracy of these three techniques and whether there is an association with the insertion angle. Methods Two OMIs were digitally planned and placed in the anterior palate of 11 human cadavers with different insertion angles. Subsequently, the position of each

In this brief essay I sketch the characteristics of an open content community by considering a number of prominent examples, reviewing sociological literature, teasing apart the concepts of open and voluntary implicit in most usages of the term, and I offer a definition in which the much maligned possibility of 'forking' is actually an integral aspect of openness. Introduction What is often meant by the term 'open' is a generalization from the Free Software, Open Source and open standards movements. Communities marshaling themselves under these banners cooperatively produce, in public view, so
