Management of Networked Sensor Systems

The ready availability of integrated circuits for sensing (MEMS), processing and wireless communication has resulted in burgeoning interest in the design, implementation, deployment, and operation of environmental sensor networks. The maintenance and control of such systems is essential to ensure eﬃcient use of resources for appropriate information gathering and processing; since most of these networks must (of necessity) operate in an unsupervised manner, these systems must also recover from partial failure or changes in the sensed environment. Currently, management functionality is inextricably intertwined with application, operating system, and/or networking components. Additionally, despite the existence of management frameworks for well-resourced, wireline networks, there is no reason to believe a priori that such frameworks will apply to the resource-constrained environments of typical environmental sensor networks. We survey network management functionality in existing sensor networks (focussed on battery-powered, wireless sensors that are static or move infrequently). This survey yields a set of dimensions for the diﬀerent categories of management functionality implemented in the surveyed systems: deployment, diagnostics, application software, bandwidth, energy, and security management. We then discuss how use of such a classiﬁcation scheme can aid the structured development of the management aspects of future sensor network systems.

Maximizing Student Clinical Communication Skills in Dental Education—A Narrative Review

Dental student training in clinical communication skills and behavioral aspects of treatment are lauded as clinically meaningful in the dental education literature. However, many dental school curricula still only provide didactic, one-time coursework with multiple choice examination assessment and little or no student skill-activating activities. This article aims to review literature relevant to optimizing clinical communication and behavioral skills in dental education. The review summarizes findings of several relevant reviews and usable models to focus on four themes: (1) special characteristics of dentistry relevant to communication skill needs, (2) essential components of dental student learning of communications skills, (3) clinical consultation guides or styles and (4) optimal curricular structure for communication learning effectiveness. Contexts of communications in the dental chair differ from medical and other allied health professions, given the current mostly dentist-dominant and patient-passive relationships. Patient-centered communication should be trained. Dental students need more practical learning in active listening and patient-centered skills including using role-play, videotaping and ultimately, real patient training. Medical consultation guides are often unwieldy and impractical in many dental contexts, so a shortened guide is proposed. Communication skills need to be learned and taught with the same rigor as other core dental skills over the entire course of the dental curriculum.
Swimming with the “Current”: An Access-Informed Exploration of Envisioned Blended Learning at Tishreen University in Syria

Today, Tishreen university in Syria is translating its emergency response to crises-prompted disruptions into an intentional blended learning model through the official inception of Moodle. The present study adopts a holistic approach to explore faculty's perceptions of this transition at the Higher Institute of languages. To this end, four pilot interviews, the researcher’s lived experience and the literature were used to design a web-based questionnaire. The questionnaire, completed by 23 teachers, elicited comparative reflections on teachers’ access to Moodle as opposed to their other digitally mediated informal experiences of access, mainly to YouTube. Analysis was largely informed by the digital divide layers: physical-material, instrumental (tool-related), substantial (content-related), motivational, and usage-related. The article argues that re-thinking academic structure and infrastructure is irreducibly grounded in formal-informal networked experiences. Although access divide models have evolved vertically into layers or generations, the current study suggests the need for a horizontal expansion. Firstly, current access divide models do not lucidly reflect distinctions between formal and informal access. Since the digital landscape we increasingly inhabit is not monthlithic in terms of its affordances, structure, modality or genre of information; formal and informal access outcomes are necessarily diverse, yet dynamically intersecting. Secondly, despite accentuating the role of digital proficiency theoretically, access research only tangentially differentiates between the consumption versus production dimensions of substantial content-related skills access. Questions regarding the impact of access on effective blended learning models in general and on academic knowledge in particular, emerge from the data. It is hoped that future research will fathom these distinctions and the relationships between them more profoundly to empower similar initiatives of transition. This is particularly impactful in a country like Syria where an added political-economic affordability layer engulfs the existing physical divide, resulting in mounting boundaries to digital academic and professional knowledge.
Minimal invasive surgery (MIS) with and without advanced platelet-rich fibrin (PRF) in treatment of localized periodontitis stage III grade B

Objectives : The objective of this study was to evaluate and compare between minimal invasive surgical treatment (MIST) with and without platelet-rich fibrin (PRF) in patient with localized periodontitis stage III grade B. Subjects and methods : A total of twenty two patients were 10 females and 12 male in this study. The study was designed as Randomized, controlled, parallel, single- blinded clinical trial. The patients were divided into two groups using split mouth technique. The study protocol involved a screening appointment, initial phase therapy, surgical therapy, all patients followed up for 6 months. The defect-associated interdental papilla was surgically approached with modified papilla preservation technique MPPT Cortellini et al. 1995. Results : The results of the present study showed similar reductions in PPD at the deepest site in both groups after 6 months of follow-up (PPD, 3.18±1.12 mm in the MIS without PRF group and 3.23±0.61 mm in the M-MIST with PRF group), for CAL gain a higher mean value was recorded in the MIS with PRF group, with a mean 2.13±0.77, in comparison to 1.90±0.94 in control group (MIS without PRF), with no significant difference. Conclusions : The platelet-rich fibrin when combined with minimally invasive surgery, produces better outcomes compared to the open flap debridement alone.
Grating couplers under flood illumination as a low-cost readout mechanism for photonic sensors

Grating couplers are a vital component for integrated photonics, as they provide an interface with the chip from anywhere on the surface. Conventionally, they are used with optical fibers, providing excellent power efficiency. The grating couplers are designed to match the size of the fiber mode. The alignment of the fiber to the chip requires high precision, rendering the couplers incompatible with applications where a low cost is crucial, like point-of-care biosensors. We present a reoptimization of grating couplers, for usage with a light source that illuminates an area much larger than the grating coupler, strongly reducing the required precision.
Neurotoxic Astrocytes Directly Converted from Sporadic and Familial ALS Patient Fibroblasts Reveal Signature Diversities and miR-146a Theragnostic Potential in Specific Subtypes

A lack of stratification methods in patients with amyotrophic lateral sclerosis (ALS) is likely implicated in therapeutic failures. Regional diversities and pathophysiological abnormalities in astrocytes from mice with SOD1 mutations (mSOD1-ALS) can now be explored in human patients using somatic cell reprogramming. Here, fibroblasts from four sporadic (sALS) and three mSOD1-ALS patients were transdifferentiated into induced astrocytes (iAstrocytes). ALS iAstrocytes were neurotoxic toward HB9-GFP mouse motor neurons (MNs) and exhibited subtype stratification through GFAP, CX43, Ki-67, miR-155 and miR-146a expression levels. Up- (two cases) and down-regulated (three cases) miR-146a values in iAstrocytes were recapitulated in their secretome, either free or as cargo in small extracellular vesicles (sEVs). We previously showed that the neuroprotective phenotype of depleted miR-146 mSOD1 cortical astrocytes was reverted by its mimic. Thus, we tested such modulation in the most miR-146a-depleted patient-iAstrocytes (one sALS and one mSOD1-ALS). The miR-146a mimic in ALS iAstrocytes counteracted their reactive/inflammatory profile and restored miR-146a levels in sEVs. A reduction in lysosomal activity and enhanced synaptic/axonal transport-related genes in NSC-34 MNs occurred after co-culture with miR-146a-modulated iAstrocytes. In summary, the regulation of miR-146a in depleted ALS astrocytes may be key in reestablishing their normal function and in restoring MN lysosomal/synaptic dynamic plasticity in disease sub-groups.
Synthesis and Characterization of High-Entropy-Alloy-Type Layered Telluride MBi2Te4 (M = Ag, In, Sn, Pb, Bi)

Recently, high-entropy alloys (HEAs) and HEA-type compounds have been extensively studied in the fields of material science and engineering. In this article, we report on the synthesis of a layered system MBi2Te4 where the M site possesses low-, middle-, and high-entropy states. The samples with M = Pb, Ag1/3Pb1/3Bi1/3, and Ag1/5In1/5Sn1/5Pb1/5Bi1/5 were newly synthesized and the crystal structure was examined by synchrotron X-ray diffraction and Rietveld refinement. We found that the M-Te2 distance was systematically compressed with decreasing lattice constants, where the configurational entropy of mixing at the M site is also systematically increased. The details of structural refinements and the electrical transport property are presented.
The effect of social media influencers’ credibility on consumer’s purchase intentions through attitude toward advertisement

People incorporate and use the internet in their lives in line with the development of technology. Facebook, Twitter, Instagram, which are especially defined as social media (SM) tools, are among the daily routines of people. Thus, a great transformation has occurred in the SM advertising industry. Social media influencers (SMI) emerged as a result of facilitating communication on SM. Unlike other studies mostly evaluated over celebrities and no detailed on how SMI affects consumers purchasing behavior through advertisement, this study shows how the SMI affects consumer purchasing behavior by considering the sample size and for the first time conducted with a survey to fill the gap in the field. This study was an attempt to explore the effects of the influencers used as product supplements in advertisements in SM tools on consumers' advertisements and purchasing intentions. Stimulatingly, this study explore how SMI’s credibility effects customer purchase intention through advertisements. In line with this, Structural Equation Modeling (SEM) was used to clarify the model and to test hypotheses. Results show that the trustworthiness, expertise, and attractiveness of the influencer have a positive effect on the attitude towards the advertisement, while the attitude towards the advertisement had no effect on the purchase intention. These results might be guideway for businesses to pay more attention to the SMI attracting the consumer's attention, having sufficient equipment about the subject and how gaining the trust of the consumer through SMI.
Usefulness of the Modified Videofluoroscopic Dysphagia Scale in Determining the Allowance of Oral Feeding in Patients with Dysphagia Due to Deconditioning or Frailty

Introduction: In patients with dysphagia due to deconditioning or frailty, as with other disorders that cause swallowing disorders, the videofluoroscopic swallowing study (VFSS) is the gold standard for dysphagia evaluation. However, the interpretation of VFSS results is somewhat complicated and requires considerable experience in the field. Therefore, in this study we evaluated the usefulness of the modified videofluoroscopic dysphagia scale (mVDS) in determining whether to allow oral feeding in patients with dysphagia due to deconditioning or frailty. Methods: Data from the VFSS of 50 patients with dysphagia due to deconditioning or frailty were retrospectively collected. We evaluated the association between mVDS and the selected feeding method based on VFSS findings, and between mVDS and the presence of aspiration pneumonia. Results: Multivariate logistic analysis showed that the mVDS total score had a significant association with oral feeding methods based on VFSS findings in patients with dysphagia due to deconditioning or frailty (p < 0.05). In the receiver operating characteristic (ROC) curve analysis, the area under the ROC curve for the selected feeding method was 0.862 (95% confidence interval, 0.747–0.978; p < 0.0001). Conclusions: mVDS seems a valid scale for determining the allowance of oral feeding, and it can be a useful tool in the clinical setting and in studies that aim to interpret VFSS findings in patients with dysphagia due to deconditioning or frailty. However, studies involving a more general population of patients with dysphagia due to deconditioning or frailty are needed.
EFFECT OF DEGREE OF PALATAL COVARAGE OF IMPLANT RETAINED MAXILLARY OVERDENTURE ON THE CRESTAL BONE LOSS

Objectives: To radiographically evaluate the effect of the degree of palatal coverage on crestal bone height around maxillary hybrid -implants. Methods: Fourteen edentulous patients with conventional maxillary and mandibular complete dentures were included in this study. Four hybrid implants (one piece 3 mm in diameter, 12 mm in length) were installed in maxillary arch of each patient in areas of lateral incisors and first premolars to retain maxillary implant overdenture then the upper denture was modified by reduction of the palatal coverage area for half of the patients and was followed radiographically for one year. Results: In this study, at the end of follow up period, there was statistically significant difference between the two groups regarding the average bone loss around the dental implants as shown by student t-test. The least bone loss was reported around the implants in group I. After six months, the mean differences of bone height loss were (0.745 ± 0.098) and (0.77 ± 0.051) mm while from six to twelve month, the mean differences of bone height loss were (0.50 ± 0.041) and (0.57 ± 0.036) mm in group I and group II respectively. Conclusion: Bone height loss around implants was increased by reduction of the palatal coverage.
Prevalence of Moderate to Severe Periodontitis in an 18–19th Century Sample—St. Bride’s Lower Churchyard (London, UK)

The aim of the study was to determine the prevalence of moderate to severe periodontitis in 18–19th century skulls in the St Bride’s Lower Churchyard in London, UK. Materials and methods: A total of 105 adult skulls (66 M: F 39) from the Museum of London collection were examined for evidence of dental disease. The primary method was to measure the presence of moderate to severe periodontitis. Other dental pathologies were recorded such as tooth wear, calculus, and caries. Results: Overall, the prevalence of moderate to severe periodontitis in the sample was 21–24%. Males were observed to be more susceptible to periodontal disease than females. The severity of bone loss in the skull collection also increased with age. There was no significant difference in the amount of calculus deposition when comparing either age or sex. A total of 14% of the individuals in the sample showed signs of smoking. Conclusion: The results of the study indicated that the prevalence of moderate to severe periodontitis in an 18–19th century skull sample was 21–24%, which was higher than in previous studies. This may be due to the lack of basic personal mouth care and professional dental treatment as well as known risk factors such as smoking, stress, low socioeconomic status, and malnutrition.
Interpersonal emotion regulation strategy choice in younger and older adults

ABSTRACT When managing their emotions, individuals often recruit the help of others; however, most emotion regulation research has focused on self-regulation. Theories of emotion and aging suggest younger and older adults differ in the emotion regulation strategies they use when regulating their own emotions. If how individuals regulate their own emotions and the emotions of others are related, these theorised age differences may also emerge for interpersonal emotion regulation. In two studies, younger and older adults’ intrapersonal and interpersonal emotion regulation strategy choices were examined via self-report and behavioural assessments of regulating the emotions of another participant (Study 1; N = 80) and of a virtual human (Study 2; N = 100). Across both studies, younger adults reported greater intrapersonal suppression but not greater reappraisal. Younger and older adults were generally similar (supported by Bayesian analyses) for both self-reported and behavioural interpersonal emotion regulation strategies. Behavioural interpersonal emotion regulation was not related to self-reported intra- and interpersonal preferences. These results suggest interpersonal emotion regulation in ageing may show distinct patterns from theorised age differences in intrapersonal emotion regulation.
Particle Number Concentration: A Case Study for Air Quality Monitoring

Particle matter is one of the criteria air pollutants which have the most considerable effect on human health in cities. Its legislation and regulation are mostly based on mass. We showed here that the total number of particles and the particle number concentrations in different size fractions seem to be efficient quantities for air quality monitoring in urbanized areas. Particle number concentration (N) measurements were realized in Budapest, Hungary, for nine full measurements years between 2008 and 2021. The datasets were complemented by meteorological data and concentrations of criteria air pollutants. The annual medians of N were approximately 9 × 103 cm−3. Their time trends and diurnal variations were similar to other large continental European cities. The main sources of N are vehicle road traffic and atmospheric new aerosol particle formation (NPF) and consecutive growth events. The latter process is usually regional, so it appears to be better assessible for contribution quantification than mass concentration. It is demonstrated that the relative occurrence frequency of NPF was considerable, and its annual mean was around 20%. NPF events increased the contribution of ultrafine (UF < 100 nm) particles with respect to the regional particle numbers by 12% and 37% in the city center and in the near-city background, respectively. The pre-existing UF concentrations were doubled on the NPF event days.
Effect of Fiber Mass Fraction on Microstructure and Properties of 2D CF-GO/EP Composite Prepared by VIHPS

Graphene is often used to improve interlaminar fracture toughness of carbon fiber/epoxy resin (CF/EP) composites. It is still a challenge to improve the toughness while maintaining the in-layer properties. In this study, 2D graphene oxide carbon fiber reinforced epoxy resin matrix (2D CF-GO/EP) composites were prepared by a vacuum infiltration hot-press forming experimental system (VIHPS), and three-point flexural and end notch flexural (ENF) tests were carried out. With the increase of the fiber mass fraction in the composites, the mode II interlaminar fracture toughness (GIIC) layers decrease gradually, and the bond property between the fiber and matrix interface layer becomes worse, because the accumulation of dense fiber bundles reduces the matrix penetration ability of cracks. However, the flexural properties increased first and then decreased, and reached the best flexural properties at 64.9%. When the fiber mass fraction is too high, the interlamellar bonding properties will decrease, and the fiber bundles will compress and affect each other. The delamination phenomenon will occur between the layers of the composites, which affects the overall bearing strength and stress limit of the composites. The results of the study show that the composites prepared by VIHPS have excellent mechanical properties, and the content of carbon fiber plays an important role in the influencing factors of the interlaminar and in-layer properties of composites.
C-Phycocyanin prevents acute myocardial infarction-induced oxidative stress, inflammation and cardiac damage

Abstract Context C-Phycocyanin is a protein with anti-scavenger, antioxidant and anti-inflammatory actions against agents that cause cellular damage. The cardioprotective action of C-phycocyanin against acute myocardial infarction (AMI) has not been studied in animal models. Objective To investigate C-phycocyanin’s effect on oxidative stress, inflammation and cardiac damage in a model of isoproterenol-induced AMI. Materials and methods Wistar rats were divided into four groups: (1) sham + vehicle (0.9% saline solution by oral gavage, OG); (2) sham + C-phycocyanin (50 mg/kg/d, OG); (3) AMI + vehicle, and (4) AMI + C-phycocyanin. AMI was induced by administering isoproterenol (20, 10, 5 and 3 mg/kg each dose per day), and serum cardiac enzymes were quantified. After five days, the animals were euthanized; the heart was dissected to determine oxidative stress, redox environment, inflammation and cardiac damage markers. Results We observed that C-phycocyanin reduced AMI-increased cardiac enzymes (CK by about 53%, CKMB by about 60%, AST by about 16% and ALT by about 21%), lipid peroxidation (57%), reactive oxygen species (50%), nitrites (46%), oxidized glutathione (41%), IL1β (3%), INFγ (5%), TNFα 3%), Bcl2 (37%), Bax (43%), COX2 (21%) and caspase 9 (61%). Finally, C-phycocyanin reduced AMI-induced aberrant histological changes related to myonecrosis, interstitial oedema and inflammatory infiltration in the heart muscle. Conclusions C-Phycocyanin prevents AMI-induced oxidative stress, inflammation and heart damage. This study is the first report that employed C-phycocyanin in an animal model of AMI and supports the potential use of C-phycocyanin in the management of AMI.
