Proportional Fairness for Long-Term Evolution-Licensed Assisted Access (LTE-LAA) with Wi-Fi Coexistence in Unlicensed Spectrum

Long-Term Evaluation-Licensed Assisted Access (LTE-LAA) has good potential for fair coexistence with Wi-Fi in an unlicensed spectrum. Though the LTE-LAA utilizes the same listen before-talk technique as the distributed coordination function in IEEE 802.11, it utilizes completely different parameters and transmission durations. For this reason, a fair coexistence between LTE-LAA and Wi-Fi leaves an open question on how the LTE-LAA network should choose its parameters. To tackle this issue, an analytical framework considering the effects of varying important parameters, which are the different initial back-off window sizes, the numbers of sensing durations, the maximum back-off stages, the number of retransmissions and the transmission opportunities for LTE-LAA and Wi-Fi nodes on their performances has been developed. The node and network airtime performances are evaluated by using the current standard parameters setting to see how this setting affects the node and network airtime performances. From there, optimal settings of the initial backoff window size and number of sensing durations are applied by using the obtained node airtime equation that is derived from the Markov renewal process and evaluated as functions of system parameters. The optimum initial backoff window size and number of sensing durations of LTE-LAA are evaluated and verified by the calculation and simulation using MATLAB software. The analysis shows that LTE-LAA maintained unfair coexistence with Wi-Fi by using the current standard parameter setting as its initial back off window size or sensing duration. But in contrast, using the optimum initial backoff window size and number of sensing durations of LTE-LAA shows that they can maintain proportional fairness. It is unconcealed that the initial backoff window size tuning of LTE-LAA carries a high possibility of achieving fairness because it needs less system data and achieves a higher exactness result.

The monotonic linear model: Testing for removable interactions.

Loftus (1978) highlighted the distinction between a theoretical concept such as memory or attention, and its observed measure such as hit rate or percent correct. If the functional relationship between the concept and its measure is nonlinear then only some interaction effects are interpretable. This is an example of the wider "problem of coordination" which pervades scientific measurement. Loftus drew on the principles of additive conjoint measurement (ACM) to discuss the consequences when the coordination function is assumed to be monotonic. This led to the distinction between removable interactions that are consistent with an additive effect on the underlying theoretical concept and nonremovable interactions that are not. However, the adoption of these ideas by researchers has been greatly limited by the fact that no statistical procedure exists to determine if and to what extent an interaction is removable or otherwise. The lack of such a procedure has similarly limited the impact of ACM on research practice. The aim of this article is to present such a procedure.

Short-term effects of Pilates-based exercise on upper limb strength and function in people with Parkinson's disease

BackgroundPeople with Parkinson's disease (PD) have impaired upper limb motor coordination, limiting the execution of activities of daily living. This study investigated the feasibility and safety of a short-term Pilates-based exercise program in the treatment of upper limb motor coordination for people with PD. MethodsFifteen patients – n (%) 4 women/11 men (27/73), median [interquartile range] age 66 [9] years – participated in this quasi-experimental (before-and-after) clinical trial. Patients underwent a 6-week (30 min/day, 3 days/week) Pilates exercise program using Reformer, Cadillac, Chair, and Barrel equipment. Feasibility was evaluated by adherence to the program and the ability to perform the exercises including progressions on difficulty. Safety was evaluated based on self-reported adverse events. Clinical and functional trends before and after the intervention were also computed regarding handgrip strength (HGS), fine motor coordination (9 Hole Peg Test; 9HPT), bradykinesia (Movement Disorder Society – Unified Parkinson's disease Rating Scale; MDS-UPDRS), and upper limb functionality (Test D'évaluation des Membres Supérieurs des Personnes Âgées, TEMPA). ResultsOf the 18 Pilates sessions, exercise adherence was 100%. The only adverse event observed was mild muscle pain. Pre-post differences were observed only for body bradykinesia and hypokinesia (1.0 [0.0] vs. 0.0 [1.0] s, adjusted p = 0.048). ConclusionsA short-term Pilates-based exercise program in the treatment of upper limb muscle strength, manual dexterity, bradykinesia, and functionality is feasible and safe for people with PD. Changes in upper limb bradykinesia encourage randomized clinical trials.

The effects of contractual and relational governance on public‐private partnership sustainability

AbstractThe study investigates how contractual and relational governance influence partner behaviors and promote sustainability performance of infrastructure public‐private partnerships (PPPs). Survey data from 217 Chinese PPP projects were analyzed using partial least squares structural equation modeling. This study found that both contractual and relational governance have positive effects on PPP sustainability, with contractual governance having a stronger impact. Contractual governance complements relational governance in promoting cooperative behavior, but relational governance does not amplify the effect of contractual governance on opportunistic behavior. The findings highlight the role of contracts in curbing opportunism and promoting collaboration via multiple functions of control, coordination, and adaption, while also revealing the limitations of relational approaches in the context of government‐business relationships and performance ambiguity. This study contributes to the PPP governance literature by uncovering the individual and interactive effects of contractual and relational governance on the economic, social, and environmental aspects of PPP sustainability.

Optimization of Algorithms and Models in Two Scenarios for Picking up-Dropping off Disaster Victims in Islands Cities

Earthquakes in the past have caused significant damage, injuries, and deaths. The remaining resources do not equal the amount needed. For this reason, effective and efficient disaster management methods are needed. Learning from recent research that describes how they optimize the coordination function of hospital systems to overcome the imbalance between need and care capacity, we add the bed occupancy ratio (BOR) of healthcare facilities to the modeling. This paper aims to provide information about the distribution mechanism for injured victims by minimizing the total time to arrive at the healthcare facility. This victim evacuation modeling uses the integer linear programming method with two scenarios. Simulations were carried out on 164 injured victims, estimated by residents who live in areas that cross the Great Sumatran fault. The results show that the second scenario, which involves distributing it to the nearest healthcare facility, is 3.6 hours shorter compared to taking it to the general hospital in the first scenario.

Does somatosensory discrimination therapy alter sensorimotor upper limb function differently compared to motor therapy in children and adolescents with unilateral cerebral palsy: study protocol for a randomized controlled trial

BackgroundBesides motor impairments, up to 90% of the children and adolescents with unilateral cerebral palsy (uCP) present with somatosensory impairments in the upper limb. As somatosensory information is of utmost importance for coordinated movements and motor learning, somatosensory impairments can further compromise the effective use of the impaired upper limb in daily life activities. Yet, intervention approaches specifically designated to target these somatosensory impairments are insufficiently investigated in children and adolescents with uCP. Therefore, the aim of this randomized controlled trial (RCT) is to compare the effectiveness of somatosensory discrimination therapy and dose-matched motor therapy to improve sensorimotor upper limb function in children and adolescents with uCP, who experience somatosensory impairments in the upper limb. We will further explore potential behavioral and neurological predictors of therapy response.MethodsA parallel group, evaluator-blinded, phase-II, single-center RCT will be conducted for which 50 children and adolescents with uCP, aged 7 to 15 years, will be recruited. Participants will be randomized to receive 3 weekly sessions of 45 minutes of either somatosensory discrimination therapy or upper limb motor therapy for a period of 8 weeks. Stratification will be performed based on age, manual ability, and severity of tactile impairment at baseline. Sensorimotor upper limb function will be evaluated at baseline, immediately after the intervention and after 6 months follow-up. The primary outcome measure will be bimanual performance as measured with the Assisting Hand Assessment. Secondary outcomes include a comprehensive test battery to objectify somatosensory function and measures of bimanual coordination, unimanual motor function, and goal attainment. Brain imaging will be performed at baseline to investigate structural brain lesion characteristics and structural connectivity of the white matter tracts.DiscussionThis protocol describes the design of an RCT comparing the effectiveness of somatosensory discrimination therapy and dose-matched motor therapy to improve sensorimotor upper limb function in children and adolescents with uCP. The results of this study may aid in the selection of the most effective upper limb therapy, specifically for children and adolescents with tactile impairments.Trial registrationClinicalTrials.gov (NCT06006065).

The Critical Analysis of the Lesotho Language Planning and Policy and Its Implications on Education

The paper aimed at analysing the Lesotho language policy to unmask how power is assumed to be exercised by the Lesotho policy-makers through linguistic elements and structure .The main analytical tool of this paper was critical sociolinguistics, using IGMs in Systemic Functional Linguistics, rhetorical strategies and the CDA model in which the paper analysed the relationship between discourse and society. The paper unveiled performativity (mode, censorship and interpellation and the grammatical aspects from the point of functions of co-ordination, modality and nominalisation as effective and dominant principles and tropes used by the Lesotho language policy makers to convince the citizens to acknowledge the language policy irrespective of how it overshadows the minority languages in Lesotho.

Elderberry diet enhances motor performance and reduces neuroinflammation-induced cell death in cerebellar ataxia rat models

Cerebellar ataxia (CA) is a condition in which cerebellar dysfunction results in movement disorders such as dysmetria, synergy and dysdiadochokinesia. This study investigates the therapeutic effects of elderberry (EB) diet on the 3-acetylpyridine-induced (3-AP) CA rat model. First, CA rat models were generated by 3-AP administration followed by elderberry diet treatment containing 2 % EB for 8 consecutive weeks. Motor performance, electromyographic activity and gene expression were then evaluated. The number of Purkinje neurons were evaluated by stereological methods. Immunohistochemistry for the microgliosis, astrogliosis and apoptosis marker caspase-3 was also performed. In addition, the morphology of microglia and astrocytes was assessed using the Sholl analysis method. The results showed that EB diet administration in a 3-AP ataxia model improved motor coordination, locomotor activity and neuro-muscular function, prevented Purkinje neurons degeneration, increased microglia and astrocyte complexity and reduced cell soma size. Moreover, EB diet administration decreased apoptosis in cerebellum of 3-AP ataxic model. In addition, elderberry diet treatment decreased the expression of inflammatory, apoptotic and necroptotic genes and increased the expression of antioxidant-related genes. The results suggest that the EB diet attenuates 3-AP-induced neuroinflammation leading to cell death and improves motor performance. Thus, the EB diet could be used as a therapeutic procedure for CA due to its neuroprotective effects.

An optimal scheme assists the municipalities in Fukuoka, Japan in achieving their goal of 100% renewable energy supply and future decarbonization

To achieve the net-zero greenhouse gas emissions goal by 2050, it is essential for local municipalities to clarify the current state of renewable energy (RE) development, energy balance, and future development directions. Thus, an optimal energy supply system scheme with a coordination function between municipalities has been designed for Fukuoka Prefecture. We initially examined the spatial distribution of current RE supply and energy balance at the municipality level and estimated the total supply potential of Agri-Voltaic to be approximately 4145 GWh year−1. In our analysis, we found that in 2020 (the current scenario), the share of RE supply by municipalities relative to demand ranged from 3 % to 267 %, with an average of 32 %. Grid power accounted for 84 % of the total demand. However, considering factors like a declining birth rate, an aging population, and energy saving initiatives assumed for 2050 (the future scenario), we estimate a decrease in total energy demand from the current level of 30,950 to a future level of 24,339 GWh year−1. From an emissions perspective, optimizing the promotion of additional RE sources and coordinating RE usage between municipalities in the future will help achieve the goal of 100 % RE supply, meet the future energy demand at the prefecture level, and support regional decarbonization efforts (emission reductions: 7871 GgCO2).

VoWiFi Cell Capacity Evaluation using WiFi 7 considering VBR Traffic

Deployment for Wireless Local Area Network (WLAN) technology is experiencing substantial growth. The transmission of Voice over WiFi (VoWiFi) is half-duplex due to its single-talk nature. In order to mitigate the inefficient utilization of available bandwidth, the technique of silent suppression is employed. This feature decreases the level of ambient noise and provides Variable Bit Rate (VBR) communication. To enhance the VoWiFi cell capacity, we utilized VBR traffic instead of Constant Bit Rate (CBR) traffic. In this study, we developed a mathematical model to find the number of VoWiFi users possible within a WLAN Access Point (AP) considering G.729 vocoder. Arbitration inter-frame space (AIFS) has been utilized in our study to evaluate the channel state prior to transmitting real-time data between user equipment (UE) devices. Additionally, short inter-frame spacing (SIFS) has been employed to transmit Request To Send (RTS)/Clear To Send (CTS) and Acknowledgement (ACK) frames, enabling an examination of the VoWiFi cell capacity. Again, to increase the VoWiFi cell capacity, we incorporated the compressed RTP (cRTP) protocol. Further, we conducted an analysis on the impact of retransmission on VoWiFi cell capacity. This analysis involved a comparison of the results using VBR traffic with the previous WLAN standards, namely IEEE 802.11b/g/n/ac/ax. We observed that the improvement in VoWiFi cell capacity in VBR traffic is approximately 2.6 times more than the CBR traffic. Further, our research revealed that the enhancement in VoWiFi cell capacity is approximately 1.5% higher when utilizing AIFS compared to Distributed Coordination Function (DCF) inter-frame spacing (DIFS).

The author's modification of the existing praxis classification among children with special needs in the context of their psycho-speech development

The well-known value for the speech development of children is a mastering of all praxis types. Unfortunately, no attention is paid to general praxis in the existing speech therapy literature. In addition, experts do not have a unified approach to the classification of all existing praxis types. The lack of a unified approach to the classification of main praxis types introduces some misunderstanding of its use. The purpose of the study is to develop the methodological and methodical basis for manual praxis among preschoolers with speech disorders using adaptive physical education. Materials and Methods: analysis of existing literature on research issues, systematization of the received information and its further classification; and generalization. The role of wrist functions among preschool children with speech disorders is considered. The analysis of the coordination wrist functions as the basis of manual praxis was made. The phylogenetic value of each coordination function is described. The prospects of combining the possibilities of physical education and occupational therapy in the development of wrist praxis are separately considered. A new author's classification of praxis was created based on: the ontogenetic principle of movement construction according to M. Bernstein; the topographic principle; the degree of praxis complication; and the degree of praxis development. The main methodological directions of the manual praxis development among preschoolers with speech disorders in combination with other types of praxis are formulated

Postoperative cognitive dysfunction-current research progress.

Postoperative cognitive dysfunction (POCD) commonly occurs after surgery, particularly in elderly individuals. It is characterized by a notable decline in cognitive performance, encompassing memory, attention, coordination, orientation, verbal fluency, and executive function. This reduction in cognitive abilities contributes to extended hospital stays and heightened mortality. The prevalence of POCD can reach 40% within 1 week following cardiovascular surgery and remains as high as 17% 3 months post-surgery. Furthermore, POCD exacerbates the long-term risk of Alzheimer's disease (AD). As a result, numerous studies have been conducted to investigate the molecular mechanisms underlying POCD and potential preventive strategies. This article provides a review of the research progress on POCD.

Neuroprotective action of hydroxybenzoic acid derivative with glycine (C40) in the middle cerebral artery occlusion in rats with chronic cerebral circulation insufficiency

The neuroprotective effect of a novel conjugate of hydroxybenzoic acid with glycine (C40) was investigated in a model of ischemic stroke in rats with chronic cerebral circulation insufficiency (CCCI). The study was conducted in two stages: first, CCCI was modeled by stenosing the common carotid arteries by 50 %, followed by a 60-minute middle cerebral artery occlusion (stroke) after 40 days. Compound C40 and the reference drug citicoline were administered for 10 days before stroke and for 3 days after. Further, neurological deficit (the Garcia and Combs D’Alecy scales), sensorimotor functions (Open Field test, Adhesive Removal test, and Rotarod test), cognitive impairments (Novel Object Recognition and Morris Water Maze tests), cerebral blood flow level, and endothelial function were evaluated. Animals receiving the test substances demonstrated a statistically significant reduction in neurological deficit, less pronounced motor coordination and sensorimotor function impairments, as well as fewer short-term and long-term memory deficits compared to the negative control group. The observed decrease in neurological deficit in the experimental groups was accompanied by improved endothelial function and increased cerebral blood flow. The neuroprotective effect of the novel hydroxybenzoic acid derivative with glycine (C40) was comparable to that of reference drug citicoline.

Acupuncture activates IRE1/XBP1 endoplasmic reticulum stress pathway in Parkinson's disease model rats

Acupuncture has demonstrated its efficacy as a treatment for Parkinson’s disease (PD). Thus, the objective of this study was to investigate the potential mechanisms underlying acupuncture’s effects on PD treatment. Our approach involved several steps. Firstly, we assessed the behavioral changes in PD rats, the modulation of dopamine (DA) and 5-hydroxytryptamine (5-HT) levels in the striatum, as well as the alteration in α-synuclein (α-syn) levels in the midbrain, aiming to evaluate the efficacy of acupuncture in PD treatment. Secondly, we selected endoplasmic reticulum (ER) stress inhibitors and activators to assess the impact of ER stress on PD rats. Lastly, we utilized an IRE1 inhibitor to observe the influence of acupuncture on the IRE1/XBP1 pathway in PD rats. The findings of this study revealed that acupuncture improved the autonomous motor function, balance ability, coordination, and sensory motor integration function in the PD model rats. Additionally, it increased the levels of DA and 5-HT in the striatum while decreasing the levels of α-syn in the midbrain. Acupuncture also activated the expression of ER stress in the midbrain and upregulated the expression of IRE1/XBP1 in the striatum of PD model rats. Based on these results, we concluded that acupuncture may enhance the behavior of PD rats by activating the IRE1/XBP1 ER stress pathway, associated with the reduction of midbrain α-syn expression and the increase in striatal DA and 5-HT levels in unilateral 6-OHDA lesioned rats.

Building automation by intelligent control of its environment

The fast development of digital technologies has contributed to building industry in the adoption of sophisticated strategies of automation. These strategies are oriented to control of environmental variables in the different parts of a building provided with high standards of performance in terms of both power saving and human comfort aspects. Control strategies can be expressed by means of rules that could be processed by the inference motor of an expert system. The rules of automation in this system will allow for a better integration of devices and will facilitate their interaction with the elements that define the operation of an intelligent building. According to the distributed paradigm currently used in building automation, the expert system located in the supervision computer will carry out specific functions of cooperation and intelligent coordination, reserving control strategies of each building sector for local controllers. As it is shown in this article, the use of technologies based on artificial intelligence to model and control the behavior of building automation systems contributes to optimize its performance in terms of comfort, security and energy saving.

OxyR-regulated T6SS functions in coordination with siderophore to resist oxidative stress.

The formation of reactive oxygen species is harmful and can destroy intracellular macromolecules such as lipids, proteins, and DNA, even leading to bacterial death. To cope with this situation, microbes have evolved a variety of sophisticated mechanisms, including antioxidant enzymes, siderophores, and the type VI secretion system (T6SS). However, the mechanism of oxidative stress resistance in Cupriavidus pinatubonensis is unclear. In this study, we identified Reut_A2805 as an OxyR ortholog in C. pinatubonensis, which positively regulated the expression of T6SS1 by directly binding to its operon promoter region. The study revealed that OxyR-regulated T6SS1 combats oxidative stress by importing iron into bacterial cells. Moreover, the T6SS1-mediated outer membrane vesicles-dependent iron acquisition pathway played a crucial role in the oxidative stress resistance process. Finally, our study demonstrated that the T6SS1 and siderophore systems in C. pinatubonensis exhibit different responses in combating oxidative stress under low-iron conditions, providing a comprehensive understanding of how bacterial iron acquisition systems function in diverse conditions.IMPORTANCEThe ability to eliminate reactive oxygen species is crucial for bacterial survival. Continuous formation of hydroperoxides can damage metalloenzymes, disrupt DNA integrity, and even result in cell death. While various mechanisms have been identified in other bacterial species to combat oxidative stress, the specific mechanism of oxidative stress resistance in C. pinatubonensis remains unclear. The importance of this study is that we elucidate the mechanism that OxyR-regulated T6SS1 combats oxidative stress by importing iron with the help of bacterial outer membrane vesicle. Moreover, the study highlights the contrasting responses of T6SS1- and siderophore-mediated iron acquisition systems to oxidative stress. This study provides a comprehensive understanding of bacterial iron acquisition and its role in oxidative stress resistance in C. pinatubonensis under low-iron conditions.

ЦИФРОВИЙ МЕНЕДЖМЕНТ ЯК СУЧАСНИЙ ТРЕНД РОЗВИТКУ ПІДПРИЄМСТВА

The article highlights the concept of digital management as a modern trend in the development of enterprise. The authors of the study noted that digital management is based on aspects of modern technical and economic development of society, on modern creative approaches to managing business processes of enterprise. The main directions of development of digital management are outlined. In order to study the possibility of improving the digital management system at the enterprise, it is recommended to carry out an assessment by the point method. Attention is focused on the fact that the assessment of digital management should be carried out in the context of management functions: planning, organization, coordination, motivation, control. The analysis showed that the functions of planning, organization and coordination of the accounting system of the studied enterprise function better than motivation and control. It is established that digital management is formed on the basis of a knowledge society, information use of components used in the so-called "smart society". In turn, the information and digital development of enterprises is based on information resources. The importance of information and digital management lies in its emphasis on digitalization, which is determined by the competence, qualifications and ability of specialists to solve complex computerization problems. It is determined that the main problems of digital management are that it is not sufficiently automated and developed to function independently, without the participation of managers. In addition, any changes in digitalization algorithms require the involvement of a large number of specialists, which makes the automation process even more complex than business processes without its participation. Insufficient level of qualification and insufficient number of specialists who can solve these problems promptly, do not allow you to create perfect software shells for business management. The publication identifies the tasks that need to be solved in order to create a unified system for automating business processes, as well as the parameters that allow compiling algorithms for digitalization of business management.
