Research on navigation and positioning Technology based on opportunity signal of low orbit satellite

Abstract Global Navigation Satellite System (GNSS) signals to the Earth’s surface are weak, vulnerable to interference, and require significant infrastructure investment to keep them operating. In order to get rid of the dependence on GNSS navigation system and overcome the problems such as shadow occlusion and malicious interference, opportunity signal is used to realize positioning to make up for the shortcomings in this aspect. Aiming at the limitation of coverage and availability of land-based opportunity signals at present, the opportunity signals of low-orbit satellites have the advantages of high signal power, wide coverage and no need to build additional infrastructure, etc. Therefore, space-based opportunity signal positioning by using low-orbit satellite system can be used as an effective backup or supplement to GNSS system. In this paper, the signal communication system of low orbit satellite is studied deeply, and the Doppler frequency information is obtained by using the single tone signal of the pilot frequency of low orbit satellite, and the mathematical model of instantaneous Doppler positioning and its geometric factor of accuracy is established, so as to realize the positioning ability of opportunity signal of low orbit satellite. The simulation results show that the positioning accuracy is better than 200 m using the actual low orbit satellite signals. The research results have reference significance for the theoretical research and application of location technology based on opportunity signal. By studying the communication system of low orbit satellite signal, the mathematical model of instantaneous Doppler positioning is established, and the method of obtaining Doppler frequency information by using the single tone signal of low orbit satellite signal and combining the satellite orbit information calculated by the orbit prediction model to realize low orbit satellite positioning is proposed. The measured data verification results show that the positioning accuracy of 100 meters can be achieved by using the LORB opportunity signal, and the research results have reference significance for the theoretical research and application of positioning technology based on the LORB opportunity signal.

DYADIC PREDICTORS OF AGING SATISFACTION: RELATIONSHIP QUALITY MODULATES THE IMPACT OF HEALTH RESTRICTIONS

Abstract How individuals develop perceptions of their own aging process is receiving increasing attention. While own age-related experiences are important, the aging of close others, such as parents, has been also found to play a role. Of particular interest may be parental health, yet relationship quality aspects may influence the extent to which health restrictions affect the children’s aging perceptions. Dyadic data from the Swiss “Aging Together” study were analyzed (dyad N = 98, Parent Mage = 83.85; Child Mage = 56.43). For parents, actor-partner interdependence models indicated a negative relationship between health restrictions and aging satisfaction; the more health restrictions they experienced, the less happy they were with their aging process. Parental health restrictions also played a role for children’s aging satisfaction, but the effect was dependent on how the relationship with the parent was perceived by the child; parents’ health restrictions were negatively associated with aging satisfaction of children who reported better relationship quality (i.e., less conflictual), but not with aging satisfaction of children who reported worse relationship quality (i.e., more conflictual). In addition, when the parent was more restricted, children who perceived the parent as more supportive showed lower levels of aging satisfaction, compared to children who perceived the parent as less supportive. Lastly, children’s own health restrictions had no negative impact on their aging satisfaction when they perceived the parent as more supportive. In sum, health restrictions may influence both dyadic partners’ aging satisfaction, but relationship quality modulates their impact.

Novel Biomaterials To Control Igf-I Binding And Enhance Chondrocyte Gene Therapy

Articular cartilage lesions could lead to Osteoarthritis (OA) due to the inability of cartilage to heal. Gene therapy could be used to genetically engineer chondrocytes to repair cartilage lesions. A current challenge in gene therapy is the transient exposure of the gene product and growth factor to the cells. This transient exposure of the growth factor is not sufficient to promote tissue generation. This thesis reports the development of a new material engineered to have high affinity for a therapeutic gene product. The growth factor studied in this thesis is insulin-like growth factor-I (IGF-I) for its highly anabolic effects in cartilage. One of the ways that cartilage stores IGF-I is through a group of insulin-like growth factor binding proteins (IGFBPs), such as IGFBP-5. IGF-I binding peptide sequence from IGFBP-5 was grafted onto alginate in order to retain the endogenous IGF-I produced by transfected chondrocytes. The chosen peptide sequence was KPLHALL due to its proximity to IGF-I in vivo. However, the reaction efficiency of KPLHALL is affected by the electrically charged side chain of Lysine, ? amino group NH3+. In order to perform the carbodiimide chemistry, the ? amino group NH3+ had to be protected with a protecting group. After attaching the amino acid sequence, the protecting group had to be removed with a base or acid. Such treatments can reduce the reaction efficiency by possibly reacting with the alginate or with other peptide sequences in its vicinity. The deprotection step could be avoided by using peptide sequences that avoid Lysine, but such modifications may affect the affinity of the peptide to IGF-I. Therefore, new materials were developed to test the relationship between the peptide lengths, the efficiency of grafting, and their binding affinity for IGF-I. KPLHALL, PLHALL and ALL sequences were compared by assessing the efficiency of grafting to alginate, the ability of modified polymers to bind IGF-I, and the ability to enhance matrix production by transfecting chondrocytes to produce IGF-I. This study reinforced the importance of IGF-I and the utility of controlling both growth factor production and binding, yielding an increase in matrix production.

Meditation mathematical formalism and Lorentz factor calculation based-on Mindfulness foundation

Mindfulness foundation is an excellent method of the human spiritual development by the reasonable thinking and consideration, which was established by Lord Buddha a long time ago. There are four ways of thinking and consideration-(i) form (body), (ii) sensation, (iii) spiritual and (iv) Dhamma. In this paper, we propose the use of the form consideration for the spiritual development, in which the form can be considered thoroughly inside the body by the spiritual projection. By using the nonlinear microring resonator known as a Panda-ring resonator, the electromagnetic (EM) signals called polaritons can be generated by the coupling interaction between the intense EM fields and the ionic diploes within the almost closed system, where the dipoles can obtain from the coupling between the gold grating and the strong electromagnetic fields. In the manipulation, cells, tissues, and organs inside the human body can communicate with the spiritual (polaritonic) signals and investigation. The simulation results obtained have shown that the Lorentz factor of 0.99999959 is obtained. The successively filtering of the signal circulation within the body during the meditation can be formulated and the meditation behaviors modeled. The aura, the stopping, and the cold body states can be configured and explained.

Pixel‐oriented land use classification in energy balance modelling

Mass and energy transfer between soil, vegetation and atmosphere is the process that allows to maintain an adequate energy and water balance in the earth–atmosphere system. However, the evaluation of the energy balance components, such as the net radiation and the sensible and latent heat fluxes, is characterized by significant uncertainties related to both the dynamic nature of heat transfer processes and surfaces heterogeneity. Therefore, a detailed land use classification and an accurate evaluation of vegetation spatial distribution are required for an accurate estimation of these variables. For this purpose, in the present article, a pixel‐oriented supervised classification was applied to obtain land use maps of the Basilicata region in Southern Italy by processing three Landsat TM and ETM+ satellite images. An accuracy analysis based on the overall accuracy index and the agreement Khat of Cohen coefficient showed a good performance of the applied classification methodology and a good quality of the obtained maps. Subsequently, these maps were used in the application of a simplified two‐source energy balance model for estimating the actual evapotranspiration at a regional scale. The comparison between the simulations made by applying the simplified two‐source energy balance model and the measurements of evapotranspiration at a lysimetric station located in the study area showed the applicability and the validity of the proposed methodology.

On Jump-Critical Ordered Sets with Jump Number Four

For an ordered set P and for a linear extension L of P, let s(P,L) stand for the number of ordered pairs (x, y) of elements of P such that y is an immediate successor of x in L but y is not even above x in P. Put s(P) = min {s(P, L): Llinear extension of P}, the jump number of P. Call an ordered set P jump-critical if s(P - {x}) &lt; s(P) for any x ϵ P. We introduce some theorems about the jump-critical ordered sets with jump number four.

Seventeen Cases of Daptomycin-Induced Eosinophilic Pneumonia in a Cohort of Patients Treated for Bone and Joint Infections: Proposal for a New Algorithm

Abstract Background Daptomycin is increasingly used in the treatment of bone and joint infections (BJIs) and may be responsible for daptomycin-induced eosinophilic pneumonia (DIEP), a potentially severe adverse drug reaction. The aim of this study was to describe DIEP in patients treated at a referral center for the management of BJI, and to revisit current definitions of this disease. Methods Patients treated from 1 January 2012 to 31 March 2021 were included in a prospective cohort (NCT02817711), in which all potential serious adverse events are prospectively recorded. Patients diagnosed with DIEP were retrospectively analyzed using different definitions. Results In a total of 4664 patients included in the cohort during the study period, 1021 patients (21.9%) received daptomycin, of whom 17 (1.7%) were diagnosed with DIEP. Most patients were male (n = 11 [64.7%]), and periprosthetic joint infection was the commonest BJI (n = 12 [70.6%]). Only 1 patient had bronchoalveolar lavage (BAL) eosinophil count ≥25%, while most patients had peripheral blood eosinophilia (n = 15 [88.2%]). Chest computed tomography (CT) was compatible with eosinophilic pneumonia in 13 of 14 cases (92.9%). All patients recovered upon discontinuation of daptomycin. Using the different definitions available, only a minority of cases fulfilled existing criteria for DIEP. We propose a new algorithm that includes specific CT scan signs, and systemic instead of BAL eosinophilia. Conclusions DIEP is a rare event that requires prompt discontinuation of the causative antibiotic. Current criteria to diagnose definite DIEP are too restrictive and not easily applicable in clinical practice. A new algorithm is proposed here (Lyon algorithm) to facilitate the early identification of DIEP.

A Technique for Estimating the Probability of Detecting a Nongaming Drug User

Abstract To evaluate the effectiveness of random urinalysis drug testing strategies, it is necessary to estimate the probability of detecting drug users, that is, the probability that users will be selected for drug testing and test positive. Methodologies were developed for estimating the probability of detecting nongaming drug users under a variety of drug wear-off models. It was observed that the probability of detection is proportional and the expected number of months until detection is inversely proportional to the monthly test rate.

The Comparison of Healthy and Unhealthy Perfectionism and Type A Personality in The Perceived Parenting Styles in University Students

The purpose of the present research is to study healthy and unhealthy perfectionism as well as type A personality based on different parenting styles. With a ex-post-facto method, a sample of undergraduate students at Shahid Beheshti University was selected through random multistage cluster sampling with at least 80 students in every parenting style. This sample consists of 407 students: 235 girls and 172 boys. The subjects completed three questionnaires of perceived parenting style, positive and negative perfectionism scale and type A personality. The collected data was analyzed by statistical tests MANOVA and ANOVA and Scheffe post hoc test. Results indicated that healthy perfectionism in the authoritative parenting style is more and in negligent parenting style is lower than the other parenting styles. The unhealthy perfectionism of the boys was more than girls. The interactive effect of the two variables namely parenting styles and gender upon healthy perfectionism was significant. Healthy­ perfectionism in authoritative parenting style in girls was more than boys and in permissive parenting style healthy perfectionism in boys was more than girls. The general effect of parenting styles and general effect of gender in score of type A personality did not show significant difference; however, the interactive effect of parenting styles and gender upon type A personality was supported. Here in permissive parenting style the type A personality in boys is higher than girls and in authoritarian parenting style the type A personality in girls is higher than boys. Conclusion: Due to the crucial role of parents' parenting styles in creating healthy and unhealthy perfectionism and also due to interactive effect of parenting style and gender on the healthy perfectionism and type A personality, educating parents on parenting styles and also giving instruction to the families for raising healthy persons in the society is a high priority.

The effect of ventricular assist devices on cerebral blood flow and blood pressure fractality

Biological signals often exhibit self-similar or fractal scaling characteristics which may reflect intrinsic adaptability to their underlying physiological system. This study analysed fractal dynamics of cerebral blood flow in patients supported with ventricular assist devices (VAD) to ascertain if sustained modifications of blood pressure waveform affect cerebral blood flow fractality. Simultaneous recordings of arterial blood pressure and cerebral blood flow velocity using transcranial Doppler were obtained from five cardiogenic shock patients supported by VAD, five matched control patients and five healthy subjects. Computation of a fractal scaling exponent (alpha) at the low-frequency time scale by detrended fluctuation analysis showed that cerebral blood flow velocity exhibited 1/f fractal scaling in both patient groups (alpha = 0.95 +/- 0.09 and 0.97 +/- 0.12, respectively) as well as in the healthy subjects (alpha = 0.86 +/- 0.07). In contrast, fluctuation in blood pressure was similar to non-fractal white noise in both patient groups (alpha = 0.53 +/- 0.11 and 0.52 +/- 0.09, respectively) but exhibited 1/f scaling in the healthy subjects (alpha = 0.87 +/- 0.04, P &lt; 0.05 compared with the patient groups). The preservation of fractality in cerebral blood flow of VAD patients suggests that normal cardiac pulsation and central perfusion pressure changes are not the integral sources of cerebral blood flow fractality and that intrinsic vascular properties such as cerebral autoregulation may be involved. However, there is a clear difference in the fractal scaling properties of arterial blood pressure between the cardiogenic shock patients and the healthy subjects.

Nasal decontamination for the prevention of surgical site infection in <i>Staphylococcus aureus</i> carriers

There is currently limited rigorous RCT evidence available regarding the clinical effectiveness of nasal decontamination in the prevention of SSI. This limitation is specific to the focused question our review addresses, looking at nasal decontamination as a single intervention in participants undergoing surgery who are known S aureus carriers. We were only able to identify two studies that met the inclusion criteria for this review and one of these was very small and poorly reported. The potential benefits and harms of using decontamination for the prevention of SSI in this group of people remain uncertain.
