Conflation of satellite altimetry and tide gauge records at coast
Authors: Iz H. Bâki , Shum C. K. , Yang T. Y. 
Published: November 2020

Abstract
This study demonstrates that absolute (geocentric) and relative sea level trends, sea level acceleration, low frequency sea level variations and linear trends in vertical crustal movements experienced at a tide gauge station can be estimated simultaneously using conflated satellite altimetry and tide gauge measurements without the aid of GPS measurements. The formulation is the first of its kind in sea level studies and its effectiveness is exemplified using tide gauge, and satellite altimetry measurements carried out in the vicinity of a tide gauge station.

Abstract

Objectives
A recent discussion surrounding the extension of antenatal corticosteroid (ACS) use beyond 34 weeks of gestation did not include the subgroup of infants of diabetic mothers (IDM). We aimed to examine the association between ACS exposure and outcomes in neonates born at term and at near-term gestation in a large cohort of IDMs.

Methods
We selected 13976 eligible near-term and term infants who were included in the PEARL-Peristat Perinatal Registry Study (PPS). We assessed the association of ACS exposure with neonatal outcomes in a multivariate regression model that controlled for diabetes mellitus (DM) and other perinatal variables.

Results
The incidence of DM was 28% (3,895 of 13,976) in the cohort. Caesarean section was performed in one-third of the study population. The incidence of ACS exposure was low (1.8%) and typically occurred>2 weeks before delivery. The incidence rates of respiratory distress syndrome (RDS)/ transient tachypnoea of newborns (TTN), all-cause neonatal intensive care unit (NICU) admissions, NICU admissions for hypoglycaemia, and low 5-min Apgar scores were 3.5, 8.8, 1.3, and 0.1%, respectively. In a multivariate regression model, ACS was associated with a slight increase in NICU admissions (OR: 1.44; 95% CI: 1.04–2.03; p=0.028), but not with RDS/TTN.

Conclusions
Although the low exposure rate was a limitation, ACS administration did not reduce respiratory morbidity in near-term or term IDMs. It was independently associated with an increase in NICU admissions. Randomized controlled trials are required to assess the efficacy and safety of ACS administration in diabetic mothers at late gestation.
Psychosocial benefit and adherence of adolescents with chronic diseases participating in transition programs: a systematic review
Authors: Ravens Esther , Becker Johanna , Pape Lars , Ernst Gundula 
Published: November 2020

AbstractChronically ill young people must transition to the adult health care service after their 18th birthday. The transition from child centred paediatric care to the adult health care service is not simply limited to the change from familiar structures to something unknown, but includes the entire process of growing up, of individuals becoming independent from their parents and taking responsibility for their own disease management. Young people are at particular risk of losing the connection to medical care during this phase and the transition of young people with chronic conditions is associated with a high risk of declining adherence and worsening health status. Studies suggest that transition programs might be helpful, yet there is no evidence as to whether risks can be reduced or which intervention components are particularly conducive to better outcome. This study aimed to identify transition-specific interventions and evaluate their effect on the improvement of psychosocial parameters, such as health related quality of life and adherence of patients. A systematic literature review was conducted. Electronic databases (Cochrane, Embase, Pubmed, Web of Science) were searched by two independent reviewers for intervention studies aiming to improve transition. Grey literature was also searched. Studies were included if they evaluated transition-specific interventions aiming to improve psychosocial or adherence parameters of participants aged 12 years and older suffering from a chronic condition. Both controlled trials and studies with measurements before an after the intervention were included. The GRADE approach was used to assess the quality of evidence. The inclusion criteria was met by forty studies. Patients suffered from different chronic conditions, such as inflammatory bowel disease, type 1 diabetes or juvenile idiopathic arthritis. Transition interventions used several program components, such as transition coordinators, patient education programs or web-based interventions. Outcomes included quality of life, transition-specific knowledge, adherence and loss to follow up. Thirty-eight studies showed beneficial effects in the intervention group, respectively after intervention. The overall study quality was low. A large number of studies evaluating transition-specific interventions was included. Transition-specific interventions seem to have beneficial effects on psychosocial outcomes and adherence. The promotion of health literacy, appointment arrangement service and the use of technical elements (websites, SMS) seem to be particularly helpful in the transition process. As the patient population was diverse, the results can be transferred to other diseases. Even though the overall study quality was poor, it is possible to draw some conclusions. Future studies should aim to include large numbers of patients over extended periods of time in order to assess long-term outcomes.

Drift velocity in GaN semiconductors: Monte Carlo simulation and comparison with experimental measurements
Authors: Kablukova Evgenia , Sabelfeld Karl , Protasov Dmitrii Y. , Zhuravlev Konstantin S. 
Published: November 2020

Abstract
Monte Carlo algorithms are developed to simulate the electron transport in semiconductors.
In particular, the drift velocity in GaN semiconductors is calculated, and a comparison with experimental measurements is discussed.
Explicit expressions for the scattering probabilities and distributions of the scattering angle of electrons on polar optical and intervalley phonons, and acoustic deformation potential as well are given.
A good agreement of the simulation results and the experimental measurements reveals that the M-L valley is located at 0.7 eV higher than the Γ-valley.
This value agrees with other experimental studies, while it is lower compared to ab initio calculations.

Published: November 2020

Abstract
The coronavirus disease 2019 (COVID-19) has become a global pandemic, which is induced by infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Patients with systemic lupus erythematosus (SLE) are susceptible to infections due to the chronic use of immunosuppressive drugs and the autoimmune disorders. Now we report a case of SLE infected with SARS-CoV-2, influenza A virus and Mycoplasma pneumoniae concurrently. The patient used hydroxychloroquine and prednisone chronically to control the SLE. After infection of SARS-CoV-2, she was given higher dose of prednisone than before and the same dosage of hydroxychloroquine. Besides, some empirical treatments such as antiviral, antibiotic and immunity regulating therapies were also given. The patient finally recovered from COVID-19. This case indicated that hydroxychloroquine may not be able to fully protect SLE patient form SARS-CoV-2. Intravenous immunoglobulin therapies and increased dose of corticosteroids might be adoptable for patient with both COVID-19 and SLE. Physicians should consider SARS-CoV-2 virus test when SLE patient presented with suspected infection or SLE flare under the epidemic of COVID-19.

Published: November 2020

Abstract
The present literature review explores research on characteristics of effective Living Learning Communities as a means to inform the continued development of a new LLC at Cleveland State University, a large urban, Predominately White University (PWU). Research on retention and persistence is explored with respect to students’ strengths and developmental prerequisites, rather than having a hyper-focus on deficits in effort to inform the continued development of an LLC at Cleveland State University. The objective is to create an LLC that showcases a balanced approach, where students’ needs are addressed while helping them realize and harness their individual strengths for success in college and beyond. Research regarding the perspectives of students who attended LLCs at PWUs as well as short and long-term outcomes for students in terms of persistence, retention, GPA, and future projections, in order to develop a successful LLC, is reviewed.

Published: November 2020

Abstract
Mid-infrared (MIR) photonics has attracted tremendous interest because of its broad applications at atmospheric windows. In this work, we report high-performance MIR photonics based on large-scale and good-quality monolayer molybdenum disulfide (MoS2). The open-aperture Z-scan measurement on the nonlinear saturable absorption features shows that the as-grown monolayer MoS2 possesses a modulation depth of 26% and a low saturable intensity of 271 kW/cm2, enabling its application as an excellent saturable absorber for the MIR pulse generation. This is further evident by the measured high effective nonlinear absorption coefficient β
eff (−16 cm/MW). In addition, the two-photon absorption coefficient and the nonlinear refractive index of monolayer MoS2 are also determined by the closed-aperture Z-scan technology. As an application, we demonstrate a passively Q-switched Tm,Ho:CaLu0.1Gd0.9AlO4 (Tm,Ho:CLGA) disordered crystal laser at 2.1 μm by using the monolayer MoS2 as the saturable absorber for the first time, producing a minimum pulse width of 765 ns and a pulse repetition rate of 36 kHz. Our results demonstrate that large-scale monolayer MoS2 is a promising candidate for the MIR photonic applications.
Wide-gap photoluminescence control of quantum dots through atomic interdiffusion and bandgap renormalization
Authors: Park Kyoung-Duck , Man Minh Tan , Cho Deok-Yong , Lee Hong Seok 
Published: November 2020

Abstract
Bandgap and photoluminescence (PL) energy control of epitaxially grown II–VI quantum dots (QDs) are highly desirable for applications in optoelectronic devices, yet little work has been reported. Here, we present a wide tunability of PL emission for CdTe/ZnTe QDs through an impurity-free vacancy disordering method. To induce compressive stress at the dielectric layer/ZnTe interface, a SiO2 film is deposited onto the samples, followed by rapid thermal annealing to induce atomic interdiffusion. After the heat treatment, the PL spectra of the intermixed QDs show pronounced blueshifts in peak energy as large as ∼200 meV because of the reduced bandgap renormalization and decreased quantum confinement effects in addition to the dominant atomic interdiffusion effect. In addition, we present a thorough investigation on the modified physical properties of the intermixed QDs, including their lattice structure, thermal escape energy, and carrier dynamics, through quantitative X-ray and optical characterizations.
High-Q nanophotonics: sculpting wavefronts with slow light

Published: November 2020

AbstractDensely interconnected, nonlinear, and reconfigurable optical networks represent a route to high-performance optical computing, communications, and sensing technologies. Dielectric nanoantennas are promising building blocks for such architectures since they can precisely control optical diffraction. However, they are traditionally limited in their nonlinear and reconfigurable responses owing to their relatively low-quality factor (Q-factor). Here, we highlight new and emerging design strategies to increase the Q-factor while maintaining control of optical diffraction, enabling unprecedented spatial and temporal control of light. We describe how multipolar modes and bound states in the continuum increase Q and show how these high-Q nanoantennas can be cascaded to create almost limitless resonant optical transfer functions. With high-Q nanoantennas, new paradigms in reconfigurable wavefront-shaping, low-noise, multiplexed biosensors and quantum transduction are possible.
Fish and Chaps: Some Ethnoarchaeological Thoughts on Fish Skin Use in European Prehistory
Authors: Vávra Roman 
Published: November 2020

AbstractThe following study summarizes the available ethnographical, historical, and archaeological data about the use of fish skin as a material. Fish skin and the methods of its processing are described. The fish skin utilisation accounts from around the world are collected in an organized matter. Afterwards the various factors affecting the use of this material are discussed and some concluding remarks about the further research possibilities are proposed. The use of fish skin does not appear to be based purely on climate, subsistence strategies, or the availability of fish, but also on cultural norms and traditions. Careful hypotheses can be made by using relational analogies, but ultimately a re-examination of museum collections or new archaeological discoveries are fundamental in furthering this field of research.

Architecture choices for high-temperature synchronous machines
Authors: Juszczak Ewa Napieralska , Roger Daniel , Komeza Krzysztof , Lefik Marcin , Napieralski Piotr 
Published: November 2020

AbstractThe article proposes an analysis of the possible architectures of synchronous machines with an ability to operate at high temperatures of over 200°C in their environment. Two machine principles have been considered: the permanent magnet synchronous machine and the synchronous reluctance machine. The numerical analyses are carried out with 3D-coupled electromagnetic-fluid-thermal models; the electromagnetic one provides the local losses that give the input data to the coupled thermal-fluid analysis model for computing the temperatures inside the machines. The simulation results are used for estimating the temperature limit of each machine architecture, considering the characteristics of their critical parts.
A review of the outcomes of rigid medical thoracoscopy in a large UK district general hospital
Authors: Aujayeb Avinash , Jackson Karl 
Published: November 2020

Abstract

Objectives
Local anesthetic medical thoracoscopy (LAT) is a well-established diagnostic, therapeutic, and preventative intervention in undiagnosed pleural effusions with a high diagnostic sensitivity and low complication rates. There is a large variability in practice. We describe a nine-year experience in a large district general hospital in England.

Methods
Two hundred seventy-five patients had LAT between January 2010 and December 2018. Data on outcomes and complications were obtained from the patients’ notes, electronic records, laboratory, and radiographic findings.

Results
The main diagnoses were malignant pleural mesothelioma (MPM) (n=110, 40%), chronic inflammation/fibrinous pleuritis (77, 28%), lung cancer (26, 9.5%), and breast cancer (16, 6%). LAT failed to diagnose cancer in 7/275 patients (false-negative rate 2.5%, diagnostic sensitivity 97.5%). Out of the 105 patients with chronic inflammation/fibrinous pleuritis or atypical proliferative processes, 21 (20%) were subsequently diagnosed with malignancy. Talcum pleurodesis was performed in 146 patients, and was successful in 86%. Seventy eight (28%) patients had trapped lung; 27 of those had a repeat procedure. The median length of stay was 3.96 days. There was one hospital death (0.3% mortality). Complications of LAT included pleural (3, 1%) and wound infections (4, 1.4%), persistent air leaks (9, 3.2%), subcutaneous emphysema (10, 3.6%), and tumor extension to the access port (1, 0.3%).

Conclusions
In this cohort, LAT was safe, effective, and enabled high diagnostic sensitivity. Further areas of study include optimal sedation and anesthetic pathways and combining LAT with indwelling pleural catheters (IPC).
‘Politeness Markers’ Revisited - A Contrastive Pragmatic Perspective
Authors: Kádár Dániel Z. , House Juliane 
Published: November 2020

AbstractThis paper revisits the concept of ‘politeness marker’, by proposing the bottom-up and corpus-based model of ‘ritual frame indicating expressions’ (RFIEs). Our central argument is that, in certain linguacultures, the relationship between ‘politeness markers’ and politeness itself is significantly stronger than in others. Therefore, any theory which argues that there is a definite relationship between form and politeness - or totally rejects this relationship - is potentially problematic if it does not take a contrastive pragmatic perspective, simply because this relationship is subject to significant linguacultural variation. The contrastive pragmatic study of RFIEs also helps us to determine the relationship between forms and speech acts and, indirectly, politeness. As a case study, we examine in this paper one-word and more complex expressions which are commonly associated with the speech acts of request and apology, drawn from the typologically distant Chinese and English linguacultures.

Published: November 2020

Abstract
Vascular endothelial growth factor (VEGF) has a crucial role in the angiogenesis of various tumors, including glioma. As the levels of VEGF would change in patients with glioma, we conducted the current systematic review and meta-analysis to more clearly determine the VEGF level alterations in different grades of glioma. PubMed and Scopus databases were sensitively searched for all the possible keywords addressing glioma and VEGF. Case–control and cohort studies on human subjects, which measured VEGF levels were eligible to be included in the study. Out of a total number of 3,612 studies, 22 studies were included and 12 studies entered the meta-analysis. This review revealed that serum levels of VEGF in glioma patients were 1.56 pg/dL higher compared to healthy controls (P = 0.05). Besides, immunohistochemistry (IHC) measurement of VEGF in surgical biopsies indicated significant difference in these two groups as well (P = 0.02). Yet, there was not a significant difference between patients with low-grade gliomas (World Health Organization (WHO) grades I-II, LGG) and those with high-grade gliomas (WHO grades III-IV, HGG) (P = 0.43). The results of this systematic review and meta-analysis demonstrate that VEGF levels would significantly increase in glioma, and therefore, could be potentially considered as a biomarker for this cancer.

“In my head, I have a cleaning lady:” Symbol form and symbolic intention in the everyday use of money
Authors: McNabb Marie , Chan-Brown Karl , Keller Julia 
Published: November 2020

Abstract
Money is a symbol. Beginning with this simple notion, we have completed a qualitative study of how money exists in people’s everyday lives and how it is used symbolically. A review of the financial, economic, psychological, and semiotic literature shows that even though money is written and talked about exhaustively, little symbol theory appears in economic writing, and we rarely found money mentioned in semiotic texts. We used a qualitative, phenomenological approach to identify critical thematic elements and underlying structures of participants’ experience. We also incorporated an accepted symbol-structure template in our analysis of the functions, emotions, actions, and reactions in the transactions our participants described. Participants refer to money both as wealth in the abstract and as concrete amounts about to be used. Our analysis of money in the abstract describes a structure of experience involving belonging, privacy and secrecy, unequal distribution, quantitative uncertainty, reflections of life history, and values. Our analysis of money in the concrete reveals a symbolic intention and a variety of “Others” engaged in the symbolic action.
