Symbiotic Ambient Backscatter Systems: Outage Behavior and Ergodic Capacity

This article investigates a symbiotic ambient backscatter communication (AmBC) system, where for the primary system, a source node T1 transmits information to a destination node T2. Whereas for the backscatter system, by riding on T1’s signal, the backscatter device passively conveys its own information <inline-formula> <tex-math notation="LaTeX">$c(n)$ </tex-math></inline-formula> to T1 and T2 via backscattering. For such, the coexistence outage probability (COP) and ergodic capacity (EC) of the AmBC system are characterized for three cases of coexistence constraints, i.e., 1) both T1 and T2 decode <inline-formula> <tex-math notation="LaTeX">$c(n)$ </tex-math></inline-formula> (Case I); 2) only T2 decodes <inline-formula> <tex-math notation="LaTeX">$c(n)$ </tex-math></inline-formula> (Case II); and 3) only T1 decodes <inline-formula> <tex-math notation="LaTeX">$c(n)$ </tex-math></inline-formula> (Case III). It is analytically shown that for sufficiently high transmit signal-to-noise ratio (SNR), the COP obeys the scaling law of <inline-formula> <tex-math notation="LaTeX">$({1}/{\sqrt {P_{s}}})$ </tex-math></inline-formula> (with <inline-formula> <tex-math notation="LaTeX">$P_{s}$ </tex-math></inline-formula> denoting T1’s transmit power) for Cases I and III, whereas its scaling law is determined by <inline-formula> <tex-math notation="LaTeX">$([{\mathrm {log}(P_{s})}]/{P_{s}})$ </tex-math></inline-formula> as well as <inline-formula> <tex-math notation="LaTeX">$({1}/{P_{s}})$ </tex-math></inline-formula> for Case II. In addition, it is shown that the restriction condition of decoding <inline-formula> <tex-math notation="LaTeX">$c(n)$ </tex-math></inline-formula> at T1 results in a dominating term <inline-formula> <tex-math notation="LaTeX">$({1}/{\sqrt {P_{s}}})$ </tex-math></inline-formula> for the COP at high SNR, whereas the restriction condition of decoding <inline-formula> <tex-math notation="LaTeX">$c(n)$ </tex-math></inline-formula> at T2 results in an infinitesimal relative to <inline-formula> <tex-math notation="LaTeX">$({1}/{\sqrt {P_{s}}})$ </tex-math></inline-formula>. It is also shown that for different cases, the effects of the T1–T2 channel statistics on the COP are significantly different. However, unlike the metric of COP, for the EC, the impacts of decoding constraints of <inline-formula> <tex-math notation="LaTeX">$c(n)$ </tex-math></inline-formula> gradually disappear at high SNR and the ECs of the backscatter channels for Cases II and III approach, respectively, toward the counterpart for Case I.
EUROPEAN CENTRE FOR SOCIAL WELFARE POLICY AND RESEARCH

Principle 18 of the European Pillar of Social Rights ensures the right to affordable long-term care (LTC) services of good quality for everyone. The examination of unmet needs of care recipients is an important starting point for the improvement of long-term care policies towards this end. Since LTC policies often embrace the combination of formal and informal care, missing access to either might be seen as susceptible to generate unmet needs. However, even among those who combine both types of care, needs will often remain unmet. The perspectives of older people in need of care and their informal carers offer an important contribution to the detection of unmet needs, a concept which measures their experiences of the care-mix against their respective expectations.
Comment on "Pt magnetic polarization on Y3Fe5O12 and magnetotransport characteristics"

In a recent Letter [Y.M. Lu et al., Phys. Rev. Lett. 110, 147207 (2013)], Lu et al. reported on "ferromagneticlike transport properties" of thin films of Pt, deposited ex situ via sputtering on the ferrimagnetic insulator Y3Fe5O12. The authors found a magnetoresistance in Pt displaying a hysteresis corresponding to the coercive field of Y3Fe5O12, consistent with the findings of other groups. While the latter interpreted their data in terms of the recently proposed spin-Hall magnetoresistance, Lu et al. attributed their observation to a magnetic proximity effect. To support this interpretation, they measured the X-ray magnetic circular dichroism (XMCD) at the Pt L2,3 edges from a Pt/Y3Fe5O12 sample with a Pt thickness of 1.5 nm and derived an average induced magnetic moment of 0.054 Bohr magnetons per Pt atom. This is contradictory to the results of our previous comprehensive XMCD study of three different Pt/Y3Fe5O12 samples with Pt thicknesses of 3, 7, and 10 nm from which we identified an upper limit of (0.003 +/- 0.001) Bohr magnetons per Pt [Gepr\"ags et al., Appl. Phys. Lett. 101, 262407 (2012), arXiv:1211.0916].
Noiseless robust performance with structured uncertainties and initial state error

—A novel method to quantify robust perfor- mance is formulated for situations where structured parameter variations and initial state errors rather than extrane- ous noise are the main performance limiting factors. Parameter uncertainty is ubiquitous in classical control, as well as in quantum control where initial state preparation errors are prevalent. The central mathematical object is the error dynamics, the difference between nominal and perturbed dynamics, driven by the unperturbed or perturbed state, rather than an artificially imposed noise. The unperturbed versus perturbed dichotomy has the interpretation of the relative error dynamics scaled by either the unperturbed or perturbed dynamics. The unperturbed-driven error formula- tion follows the conventional lines of robust performance, but has the unique feature of decoupling the effect of the physically meaningful uncertainties from some artificial noise. However, the case of perturbed-driven error dynam- ics is a significant departure from conventional robustness in that it offers the possibility to side-step structured sin- gular value computation. Applications to a lightly damped mechanical system and a slowly dephasing quantum sys- tem demonstrate the usefulness of the concepts across a broad range of systems. Finally, a fixed point algorithm specifically developed for quantum systems with state tran-sitions depending in a nonlinear fashion on uncertainties is proposed as the substitute for classical µ .
Psycholinguistics and Aging

cognitive performance also began to be better comprehended. These new findings not only promise to change our understanding of healthy cognitive aging, but also seem likely to alter our conceptions of cognition and language themselves. et compared the performance of older and younger native German speakers on a German PAL test with that of matched groups of Chinese–German bilinguals, and found that older bilinguals outperformed native speakers in a German PAL test, an advantage that increased with age. That is, when age was controlled for, they found that less linguistic experience predicted higher PAL scores.
Power-seeking, networking and competition: why women do not rise in parties

Abstract Why do women fail to rise in parties, especially youth parties? This analysis shows that female party members’ preferences regarding the purpose of a committee, networking and the election rule in party organisations differ from male party members’ which is likely a reason why women face challenges to rise in parties. This article investigates for the first time these gender based differences in preferences simultaneously by conducting a survey experiment with youth party members. Respondents (n > 1200) were asked if they would run for a seat in a decision-making committee of their youth party. In order to analyse which youth party members opt for which opportunities, the purpose of these committees, the networking opportunities they provide, and the election rule for these committees vary at random. The results show that female members hesitate to join committees that would grant them power, and that they are less likely to opt for upward networking opportunities than their male party colleagues. This effect is particularly strong in hierarchically organised youth parties of centre-right parties. Findings on preferred election rules mostly hold for women from left-wing parties. In contrast to men, this group prefers party quotas. Analysing differences by gender and political orientation, this article shows a clear gender preference gap exists both within and across youth parties.
Assessment of KAP among the Dental Practitioners towards Prosthetic Phase of Implant in Vidarbha Region of India: A Questionnaire Study

Aims & Objectives: Implant therapy has become a significant part of day-to-today dental practice. Adequate knowledge of diagnostic as well as therapeutic options is therefore necessary for all general dental practitioners. The present study is designed to evaluate and assess the knowledge, attitude and practice of practitioners about the prosthetic phase of dental implant. As the dental implant therapy is emerging in Vidarbha region of India and lack of studies evaluating the same, we recommend that awareness regarding prosthetic phase will allow practitioners to offer extensive treatment options for patient with missing teeth using dental implants. Materials and Methods: This is an observational questionnaire survey conducted among 210 General Dental Practitioners in Vidarbha Region of India. A google form validated questionnaires distributed to assess their knowledge, attitude and practice among the study participants. Data were analysed using SPSS 22.0 version software. Results: A total of 210 dentists, nearly 69% of the participants had good knowledge of prosthetic phase of implant and majority of practitioners in the study had positive attitudes and practices toward the prosthetic phase of implant placement. Results were significant for KAP but co-relation between them was statistically not significant (p=0.12). Conclusion: In overall, practitioners have a significant level of knowledge about the prosthetic phase of an implant. There is a limitation of practise and exposure of dentists in this field of prosthetics because the majority of practitioners have not placed enough implants. Implant training and prospective prosthetic rehabilitation are thus adjuvant learning aids that will improve general dental practitioners' knowledge, attitude, and practice.
The Effect of Job and Motivation on the Knowledge Sharing of Librarians in Public Libraries

ABSTRACT The present study aimed at investigating the effect of job and motivation on the knowledge sharing of librarians in public libraries. The present study was of survey type. The statistical population of this study was all librarians in public libraries of Iran and the sample included 245 subjects. Data collection tool was a questionnaire while the structured equation modeling and Lisrel software used for analyzing data. Based on research findings, this study highlighted the role of autonomy, feedback, and external motivation on the knowledge sharing behavior of the librarian. The findings of this study showed that autonomy had a mutual effect on the introjected and external motivation of librarians. Despite the lack of relationship between task identity and introjected motivation, the task identity has a direct and significant effect on their knowledge sharing behavior. In this study, the lack of relationship between feedback and external motivation of librarians was confirmed.
The Conometric Connection for the Implant-Supported Fixed Prosthesis: A Narrative Review

Aim: The conometric concept was proposed as a possible connection between the abutment and the prosthetic coping. This research aimed to review the features and possible clinical uses of this connection in an implant-supported fixed prosthesis. Methods: An electronic search was conducted on an online database for the topic in object; articles published in international literature were considered and the research gave 17 results, and 6 parameters were analyzed. Results: This connection eliminated the possibility of cement residues in the subgingival region, reducing the risk of inflammation of peri-implant soft and hard tissues; not having to remove the cement residues, it is possible to place the margins in more apical portions, improving the aesthetics outcomes of the rehabilitations. It is also known that the retention by means of a screw causes a weakening of the restoration. The retentive force is adequate for fixed rehabilitation even after a high number of insertion–disengagement cycles; in vitro studies have also shown a high bacterial sealing. Implant rehabilitation using preformed components, such as conometric hoods, is helpful for CAD/CAM, so a digital workflow is possible. Several types of prosthesis were presented, all of which demonstrated adequate clinical performance in the follow-up observation. Conclusions: This type of connection seems to be suitable to support fixed implant rehabilitations, but long-term clinical studies are needed to validate this system.
An extensive Study of Teaching / Learning Quantum Mechanics in College

Quantum physics is considered as one of the most remarkable discoveries of contemporary physics grown during previous century and gradually manifested to the scientific world such as inventions of laser, the transistor, the electron microscope, and semiconductor. Teaching of physical science has been stressed in the National Science Education Standards (NSES) from level K-12 as well as many state science standards (Gossard, 2000). The objectives of the current study are to investigate prospective elucidation of the most common learning difficulties, insufficient teaching strategies and other significant instructional or conceptual problems encountered by science and engineering college students at the senior and/or junior level during the instruction of Quantum Physics. Although conceptual issues about learning and teaching of Quantum Physics were addressed in the current study, I mainly focused on the ways the teachers approach teaching it, as well as considerations of how the classroom environments should function. Keywords: Quantum Physics, Science Education, Teaching and Learning Science.
Disturbance of Key Cellular Subproteomes upon Propofol Treatment Is Associated with Increased Permeability of the Blood-Brain Barrier

Background: Propofol is a short-acting anesthetic, which is often used for induction and maintenance of general anesthesia, sedation for mechanically ventilated adults and procedural sedation. Several side effects of propofol are known and a substantial number of patients suffer from post-operative delirium after propofol application. In this study, we analyzed the effect of propofol on the function and protein expression profile on a proteome-wide scale. Methods: We cultured human brain microvascular endothelial cells in absence and presence of propofol and analyzed the permeability of the blood-brain barrier (BBB) by fluorescein passage and protein abundance on a proteome-wide scale by mass spectrometry. Results: Propofol interfered with the function of the blood-brain barrier. This was not due to decreased adhesion of propofol-treated human brain microvascular endothelial cells. The proteomic analysis revealed that some key pathways in these cells were disturbed, such as oxygen metabolism, DNA damage recognition and response to stress. Conclusions: Propofol has strong effects on protein expression which could explain several side effects of propofol.
Combining Deep Phenotyping of Serum Proteomics and Clinical Data via Machine Learning for COVID-19 Biomarker Discovery

The persistence of long-term coronavirus-induced disease 2019 (COVID-19) sequelae demands better insights into its natural history. Therefore, it is crucial to discover the biomarkers of disease outcome to improve clinical practice. In this study, 160 COVID-19 patients were enrolled, of whom 80 had a “non-severe” and 80 had a “severe” outcome. Sera were analyzed by proximity extension assay (PEA) to assess 274 unique proteins associated with inflammation, cardiometabolic, and neurologic diseases. The main clinical and hematochemical data associated with disease outcome were grouped with serological data to form a dataset for the supervised machine learning techniques. We identified nine proteins (i.e., CD200R1, MCP1, MCP3, IL6, LTBP2, MATN3, TRANCE, α2-MRAP, and KIT) that contributed to the correct classification of COVID-19 disease severity when combined with relative neutrophil and lymphocyte counts. By analyzing PEA, clinical and hematochemical data with statistical methods that were able to handle many variables in the presence of a relatively small sample size, we identified nine potential serum biomarkers of a “severe” outcome. Most of these were confirmed by literature data. Importantly, we found three biomarkers associated with central nervous system pathologies and protective factors, which were downregulated in the most severe cases.
Particle Distribution and Heat Transfer of SiO2/Water Nanofluid in the Turbulent Tube Flow

In order to clarify the effect of particle coagulation on the heat transfer properties, the governing equations of nanofluid together with the equation for nanoparticles in the SiO2/water nanofluid flowing through a turbulent tube are solved numerically in the range of Reynolds number 3000 ≤ Re ≤ 16,000 and particle volume fraction 0.005 ≤ φ ≤ 0.04. Some results are validated by comparing with the experimental results. The effect of particle convection, diffusion, and coagulation on the pressure drop ∆P, particle distribution, and heat transfer of nanofluid are analyzed. The main innovation is that it gives the effect of particle coagulation on the pressure drop, particle distribution, and heat transfer. The results showed that ∆P increases with the increase in Re and φ. When inlet velocity is small, the increase in ∆P caused by adding particles is relatively large, and ∆P increases most obviously compared with the case of pure water when the inlet velocity is 0.589 m/s and φ is 0.004. Particle number concentration M0 decreases along the flow direction, and M0 near the wall is decreased to the original 2% and decreased by about 90% in the central area. M0 increases with increasing Re but with decreasing φ, and basically presents a uniform distribution in the core area of the tube. The geometric mean diameter of particle GMD increases with increasing φ, but with decreasing Re. GMD is the minimum in the inlet area, and gradually increases along the flow direction. The geometric standard deviation of particle diameter GSD increases sharply at the inlet and decreases in the inlet area, remains almost unchanged in the whole tube, and finally decreases rapidly again at the outlet. The effects of Re and φ on the variation in GSD along the flow direction are insignificant. The values of convective heat transfer coefficient h and Nusselt number Nu are larger for nanofluids than that for pure water. h and Nu increase with the increase in Re and φ. Interestingly, the variation in φ from 0.005 to 0.04 has little effect on h and Nu.
Spatial Distribution and Retention in Loblolly Pine Seedlings of Exogenous dsRNAs Applied through Roots

Exogenously applied double-stranded RNA (dsRNA) can induce potent host specific gene knockdown and mortality in insects. The deployment of RNA-interference (RNAi) technologies for pest suppression is gaining traction in both agriculture and horticulture, but its implementation in forest systems is lagging. While numerous forest pests have demonstrated susceptibility to RNAi mediated gene silencing, including the southern pine beetle (SPB), Dendroctonus frontalis, multiple barriers stand between laboratory screening and real-world deployment. One such barrier is dsRNA delivery. One possible delivery method is through host plants, but an understanding of exogenous dsRNA movement through plant tissues is essential. Therefore, we sought to understand the translocation and persistence of dsRNAs designed for SPB throughout woody plant tissues after hydroponic exposure. Loblolly pine, Pinus taeda, seedlings were exposed to dsRNAs as a root soak, followed by destructive sampling. Total RNA was extracted from different tissue types including root, stem, crown, needle, and meristem, after which gel electrophoresis confirmed the recovery of the exogenous dsRNAs, which were further verified using Sanger sequencing. Both techniques confirmed the presence of the exogenously applied target dsRNAs in each tissue type after 1, 3, 5, and 7 d of dsRNA exposure. These findings suggest that root drench applications of exogenous dsRNAs could provide a viable delivery route for RNAi technology designed to combat tree feeding pests.
Urbanization and poverty in Sub-Saharan Africa: evidence from dynamic panel data analysis of selected urbanizing countries

Abstract Urbanization in Sub-Saharan Africa (SSA) is generally highlighted as a puzzle that deviates from the stylized facts in the literature. Using data from a panel of 29 urbanizing countries in SSA from 1985 to 2019, the study employs the two-step system generalized methods of moments to investigate the effect of urbanization on the Poverty Headcount ratio and Poverty Gap. The estimated urbanization elasticities of poverty indicate that at growth rates, a 1 percentage point increase in urbanization rate induces 0.04 and 0.05 (0.07 and 0.09) percentage points decrease in the Poverty Headcount ratio and Poverty Gap in the short-run (long-run), respectively. Similarly, at levels, a 1 percent increase in urbanization level induces 0.22 and 0.32 (0.60 and 0.68) percent decrease in the Poverty Headcount ratio and Poverty Gap in the short-run (long-run), respectively. Consistently, these results show stronger effect of urbanization on the depth of poverty relative to the incidence of poverty. These findings reappraise the literature on the urbanization of poverty in SSA as well as provide a nuanced understanding of the effect of urbanization on the different class of poverty measures. Notwithstanding, the poverty reduction potential of urbanization is not automatic and requires enormous investment in public infrastructure to achieve.
Impact of Patient Age on Postoperative Short-Term and Long-Term Outcome after Pancreatic Resection of Pancreatic Ductal Adenocarcinoma

Simple Summary Pancreatic ductal adenocarcinoma (PDAC) is frequently seen in elderly patients. The aim of our retrospective study was to evaluate the impact of age on postoperative short-term and long-term outcomes in patients undergoing curative pancreatic resection for PDAC. Our data confirm that pancreatic resections can be performed with equal short-term outcomes even in older age. However, patient age significantly influenced the overall and disease-free survival of patients with PDAC undergoing primary resection in curative intent. Therefore, the choice of the optimal therapy concept for each patient should be individualized taking into account the patient’s age. Abstract (1) Purpose: to evaluate the impact of age on postoperative short-term and long-term outcomes in patients undergoing curative pancreatic resection for PDAC. (2) Methods: This retrospective single-center study comprised 213 patients who had undergone primary resection of PDAC from January 2000 to December 2018 at the University Hospital of Erlangen, Germany. Patients were stratified according the age into two groups: younger (≤70 years) and older (>70 years) patients. Postoperative outcome and long-term survival were compared between the groups. (3) Results: There were no significant differences regarding inhospital morbidity (58% vs. 67%, p = 0.255) or inhospital mortality (2% vs. 7%, p = 0.073) between the two groups. The median overall survival (OS) and disease-free survival (DFS) were significantly shorter in elderly patients (OS: 29.2 vs. 17.1 months, p < 0.001, respectively; DFS: 14.9 vs. 10.4 months, p = 0.034). Multivariate analysis revealed that age was a significant independent prognostic predictor for OS and DFS (HR 2.23, 95% CI 1.58–3.15; p < 0.001 for OS and HR 1.62, 95% CI 1.17–2.24; p = 0.004 for DFS). (4) Conclusion: patient age significantly influenced overall and disease-free survival in patients with PDAC undergoing primary resection in curative intent.
