African Lisbon. Difficult Heritage, Postcolonial Relations, and Crosscultural Challenges
The aim of this article is to synthetically capture African cultural influences from former colonies and various manifestations of the „African presence” in today’s Lisbon. This „African presence”, in a broad sense, includes a number of phenomena such as the living conditions and customs of the African diaspora in Lisbon, African elements in the cultural and tourist offer of the city, the activities of afrodescendentes (people of African origin) in the area of postcolonial relations, African traces in the topography of the city, and others. African cultural heritage is presented as dissonant, ambivalent, subject to various interpretations, also through the practices of post-memory. To illustrate these issues, I refer to a few examples of artistic projects and initiatives dealing with the topic of postcolonial relations in the Portuguese context.

Contested Heritage of Predappio. Conflicting Memories and Construction of the European City
Narrative This paper is devoted to the problem of Predappio as a place of contested memory. Benito Mussolini’s hometown is presented in literature as a symbolic site of the divided memory of the fascist regime. In what follows, I will examine the process of shaping the image of Predappio from the fascist period to the present day, as well as strategies implemented by local authorities to overcome the legacy of this difficult heritage and build a positive narrative of the city.
Foreigners as actors of Europeanisation
Authors: Fantuz Fiorenzo
Published: December 2021

The article presents the conceptualisations that constitute the theoretical basis of a new study pursuing sociological understanding of some major social changes which have affected Polish cities in recent years. Poland has increasingly aligned itself with European countries in terms of political, socio-economic and cultural development. New flows of international immigration, meaning new individuals choosing Poland as the country where to work and settle, are making Polish cities more diverse and complex, both in a material and in a cultural way. The new research focuses on the role of foreigners as actors of urban diversification in Poland, analysing features of globalising cities, processes of Europeanisation, migrants’ discursive categorisation and anchoring. The article is conceived as a selection of critical problematisations.

„Misleading analogy”: About Differences Between Referendum in Scotland and Catalonia
Separatist aspirations in Europe are now a captivating issue. Regions like Scotland and Catalonia deserve special attention. The aim of the article is to show differences in the perception of both cases, due to their frequent comparing in journalistic papers. The study consists of two parts that concern Scotland and Catalonia. In each of them the institutional and legal positions of the regions were taken into the consideration. In addition, the course of events in Scotland and Catalonia in 2014 and 2017 was considered in the context of the independence referendums carried out in these regions. The summary of this article consists of comparison of the factors which show that there are no grounds for adapting analogy between Scotland and Catalonia. Factors that have been taken into account are: the legal order and the regulations used to define the legal status of the regions, and also the relations between central and subnational (regional) levels in Scotland and Catalonia.
Postfundamentals Price Drift in Capital Markets: A Regression Regularization Perspective
Authors: Avramov Doron , Kaplanski Guy , Subrahmanyam Avanidhar
Published: December 2021

Regression regularization techniques show that deviations of accounting fundamentals from their preceding moving averages forecast drifts in equity market prices. Deviations-based predictability survives a comprehensive set of prominent anomalies. The profitability applies strongly to the long leg and survives value weighting and excluding microcaps. We provide evidence that the predictability arises because investors anchor to recent means of fundamentals. A factor based on our fundamentals-based index yields economically significant intercepts after controlling for a comprehensive set of other factors, including those based on profit margins and earnings drift.

Spatio-Temporal Pricing for Ridesharing Platforms
Authors: Ma Hongyao , Fang Fei , Parkes David C.
Published: December 2021

Ridesharing platforms have radically changed the way people get around in urban areas, but there remain challenges undercutting the mission of “making transportation as reliable as running water.” A particular concern is that drivers strategize: calling riders to find out their destinations and canceling trips that are not worthwhile, declining trips and chasing surge prices in neighboring areas, and going off-line before large events will end in anticipation of a price increase.

In this work, we show that such strategic behaviors are symptoms of inefficiencies in the pricing and dispatching rules governing today's platforms. We propose the Spatio-Temporal Pricing mechanism, which solves for the welfare-optimal matching of drivers to trips, and sets prices that are appropriately smooth in both space and time such that the best thing for drivers to do is accept any proposed trip dispatch. This demonstrates that ridesharing platforms can succeed in optimally orchestrating trips and providing reliable transpiration for riders, while still leaving drivers with the flexibility to decide how to work.
The Contribution of Natural Gas to the Paradigm of Energy Transition in Portugal: Economy, Continuity of Supply and Welfare
Authors: Domingues Nuno
Published: December 2021

The present paper presents an analysis on the role of Natural Gas (NG) in Portugal facing the new requirements. The analyses is based on the economic, societal and environmental aspects, being the major reasons to align the Government strategy, define policies and reproduce the EU directives. The analyses do not reflect on the pandemic and financial crisis because the author considers that these factors are outside of the energy system and have not been steady along the period in study, thereby it can mislead the conclusions. This study relies mostly on non-empirical research, in which the research adopted both inductive and deductive reasoning to theorize logical assumptions about the Portuguese energy market. Building on reflection and personal observation on the field, the researchers carried out this article by gathering relevant data (i.e., statistics) through critical studies, systematic review of literature and meta-analysis on the theme. Therefore, the methodology used is based mainly on qualitative exploration of secondary sources and data, out of which one will pull out insights. The novelty of the study is to take in consider-ation all the above factors and produce results that are more adequate to reality, as all of them are interconnected and by changing one of them it will be changes in the remain. The open literature mainly focusses on the economic, the energetic, the social or the environmental aspects and neglects the others. One can conclude that there is economic advantage on efficiently distributing and consuming NG. Also, the impact of NG on a society welfare is positive. Last, the NG brings flexibility to the grid, which is more and more important in the perspective and ambition to increase the share of intermittent renewable energies.

Dynamic Panel Data Analysis of Capital Structure Determinants: Evidence from Iraqi Banks
Authors: Jadah Hamid Mohsin , Hasan Mohammed Faez , Al-Husainy Noor Hashim Mohammed
Published: December 2021

This study investigates if the choice of capital structure of Iraqi banks could be interpreting through factors which have been studied by prior studies, which represented by determinants of capital structure choice (i.e., bank size, bank profitability, bank growth, tangibility, bank age). Using dynamic panel GMM for the period 2005 to 2019, this study maintains the explore on the determinants of capital structure of Iraq banks "developing country" that has circumstances likely to be quite different from those in developed and other major developing countries, particularly in terms of it deteriorating economic environment. The findings indicate that the bank size, bank profitability, bank age have a dominant role in explaining the variation in the long-term debt ratios of Iraqi banks. Meanwhile, only bank size, bank profitability, bank growth, bank age has a leading role in interpreting the variation of short-term debt ratios in the Iraqi banks. The current study has initiated some basis to discover the capital structure determinants of Iraqi banks upon which a more detailed evaluation could be based. Moreover, the experimental results can help Iraqi banks directors to choose the optimum structure of capital.
Bridging Academic Entrepreneurship and the World of Work? Perspectives from Contemporary Educator
Authors: Teo Teck Choon
Published: December 2021

This contribution of this study investigates how the use of the AE toolkit can take the lead to a greater appreciation of the university spin-off venture into the real world of work. Nevertheless, no conceptual framework can explain how the technology-market matching proceeds from one stage to another. A longitudinal survey design involving four focus groups was chosen to monitor the development process of group spin-off creation in context. Data collection is also derived from the literature review, in-depth interviews, and a series of workshops and focus group discussions on the Malaysian and Cambodian higher education sectors. Finding shows that the AE toolkit is organized around four mutually dependent themes: (1) the structure of an enterprising university and its culture, (2) university spin-offs (USOs) and applied research, (3) the attribute of academic entrepreneurs and entrepreneurial ecosystem, and (4) spin-off development and community engagements. These theories may offer a more comprehensive insight into the AE process in conjunction with each other. The beliefs of each notion hint at significant consequences for further research on AE and the world of work as a general rule.

Authors: Lopez-Bassols Indira , Wet Iona de , Subramaniam Gayle , Hikal Iman
Published: December 2021

The aim of this review was to assess the impact of an NHS specialist breastfeeding clinic staffed by International Board Certified Lactation Consultants, and to identify whether it improves breastfeeding outcomes and duration. This retrospective clinical review evaluated data from consultations at the Merton Specialist Breastfeeding Clinic. The data from each consultation forms the basis of the analysis. In the majority of cases (76%; n=56), the clinician findings differed from the mother's presenting concerns. This highlights the importance of specialist care to correctly identify issues and underlying causes. The majority (83%) of infants in this cohort were receiving some mother's own milk beyond 6 months. Women who faced complex breastfeeding challenges reached their breastfeeding goals with the support of specialist lactation care.
On $m$-th roots of nilpotent matrices
Authors: Ozturk Semra
Published: December 2021

A new necessary and sufficient condition for the existence of an $m$-th root of a nilpotent matrix in terms of the multiplicities of Jordan blocks is obtained and expressed as a system of linear equations with nonnegative integer entries which is suitable for computer programming. Thus, computation of the Jordan form of the $m$-th power of a nilpotent matrix is reduced to a single matrix multiplication; conversely, the existence of an $m$-th root of a nilpotent matrix is reduced to the existence of a nonnegative integer solution to the corresponding system of linear equations. Further, an erroneous result in the literature on the total number of Jordan blocks of a nilpotent matrix having an $m$-th root is corrected and generalized. Moreover, for a singular matrix having an $m$-th root with a pair of nilpotent Jordan blocks of sizes $s$ and $l$, a new $m$-th root is constructed by replacing that pair by another one of sizes $s+i$ and $l-i$, for special $s,l,i$. This method applies to solutions of a system of linear equations having a special matrix of coefficients. In addition, for a matrix $A$ over an arbitrary field that is a sum of two commuting matrices, several results for the existence of $m$-th roots of $A^k$ are obtained.
The outcome of the uncemented acetabular component in delayed total hip arthroplasty following acetabular fractures
Authors: El-Bakoury Ahmed , Khedr Waseem , Williams Mark , Eid Yousry , Hammad Abdullah Said
Published: December 2021

Aims

After failed acetabular fractures, total hip arthroplasty (THA) is a challenging procedure and considered the gold standard treatment. The complexity of the procedure depends on the fracture pattern and the initial fracture management. This study’s primary aim was to evaluate patient-reported outcome measures (PROMs) for patients who underwent delayed uncemented acetabular THA after acetabular fractures. The secondary aims were to assess the radiological outcome and the incidence of the associated complications in those patients.

Methods

A total of 40 patients underwent cementless acetabular THA following failed treatment of acetabular fractures. The postoperative clinical and radiological outcomes were evaluated for all the cohort.

Results

The median (interquartile range (IQR)) Oxford Hip Score (OHS) improved significantly from 9.5 (7 to 11.5), (95% confidence interval (CI) (8 to 10.6)) to 40 (39 to 44), (95% CI (40 to 43)) postoperatively at the latest follow-up (p < 0.001). It was worth noting that the initial acetabular fracture type (simple vs complex), previous acetabular treatment (ORIF vs conservative), fracture union, and restoration of anatomical centre of rotation (COR) did not affect the final OHS. The reconstructed centre of rotation (COR) was restored in 29 (72.5%) patients. The mean abduction angle in whom acetabular fractures were managed conservatively was statistically significantly higher than the surgically treated patients 42.6° (SD 7.4) vs 38° (SD 5.6)) (p = 0.032). We did not have any case of acetabular or femoral loosening at the time of the last follow-up. We had two patients with successful two-stage revision for infection with overall eight-year survival rate was 95.2% (95% CI 86.6% to 100%) with revision for any reason at a median (IQR) duration of follow-up 50 months (16 to 87) months following THA.

Conclusion

Delayed cementless acetabular THA in patients with previous failed acetabular fracture treatments produces good clinical outcomes (PROMS) with excellent survivorship, despite the technically demanding nature of the procedure. The initial fracture treatment does not influence the outcome of delayed THA. In selected cases of acetabular fractures (either nondisplaced or with secondary congruency), the initial nonoperative treatment neither resulted in large acetabular defects nor required additional acetabular reconstruction at the time of THA.

Published: December 2021

No abstract available. Article truncated after 150 words. State regulatory boards that regulate professionals such as doctors, nurses, psychologists, etc. are often appointed by politicians and headed by lawyers. Under this category has been most Medical Boards and their parent organization the Federation of State Medical Boards. Although they claim to be protecting the public, they seem more concerned with identifying “disruptive” physicians and blacklisting them through the National Practitioner Data Bank (1). However, in July the Federation issued a warning to physicians against propagating COVID-19 vaccine misinformation and disinformation citing a "dramatic increase" by physicians (2). The statement gave some hope that the Federation was striving to maintain some degree of professional standards by saying that spreading disinformation to the public was dangerous because physicians enjoy a high degree of public credibility. The Tennessee Board of Medical Examiners followed the Federation’s lead by issuing a verbatim restatement warning that physicians who spread false information about COVID-19 vaccinations …
InAs/InP quantum dot mode-locked laser with an aggregate 12.544 Tbit/s transmission capacity
Authors: Liu Guocheng , Poole Philip J. , Lu Zhenguo , Liu Jiaren , Mao Youxin , Vachon Martin , Barrios Pedro
Published: December 2021

Chip-scale optical frequency comb sources are ideal compact solutions to generate high speed optical pulses for applications in wavelength division multiplexing (WDM) and high-speed optical signal processing. Our previous studies have concentrated on the use of quantum dash based lasers, but here we present results from an InAs/InP quantum dot (QDot) C-band passively mode-locked laser (MLL) for frequency comb generation. By using this single-section QDot-MLL we demonstrate an aggregate line rate of 12.544 Tbit/s 16QAM data transmission capacity for both back-to-back (B2B) and over 100-km of standard single mode fiber (SSMF). This finding highlights the viability for InAs/InP QDot lasers to be used as a low-cost optical source for large-scale networks.
Coherent supercontinuum shaping for multiple wavelength optimization over an octave
Authors: Lee Kevin F. , Rolland Antoine , Li Peng , Jiang Jie , Fermann Martin E.
Published: December 2021

We shape the spectrum of an octave spanning supercontinuum from an erbium fiber laser. The group delay dispersion is controlled through the temperature profile of a chirped fiber Bragg grating. We demonstrate control of spectral broadening, switching in spectral windows, and optimizing power at six wavelengths corresponding to Yb, Ca, and Sr clock transitions, an f-2f pair, and a C-band reference for frequency transfer applications. We verify locking of the shaped f-2f beat note, and the coherence of the shaped supercontinuum by interference with an unshaped supercontinuum branch with relative frequency deviation of 10−17 at 1 s averaging time.
Gut microbiota features associated with Clostridioides difficile colonization in dairy calves

Published: December 2021

Diarrheal disease, a major cause of morbidity and mortality in dairy calves, is strongly associated with the health and composition of the gut microbiota.Clostridioides difficileis an opportunistic pathogen that proliferates and can produce enterotoxins when the host experiences gut dysbiosis. However, even asymptomatic colonization withC.difficilecan be associated with differing degrees of microbiota disruption in a range of species, including people, swine, and dogs. Little is known about the interaction betweenC.difficileand the gut microbiota in dairy calves. In this study, we sought to define microbial features associated withC.difficilecolonization in pre-weaned dairy calves less than 2 weeks of age. We characterized the fecal microbiota of 80 calves from 23 different farms using 16S rRNA sequencing and compared the microbiota ofC.difficile-positive (n = 24) andC.difficile-negative calves (n = 56). Farm appeared to be the greatest source of variability in the gut microbiota. When controlling for calf age, diet, and farm location, there was no significant difference in Shannon alpha diversity (P= 0.50) or in weighted UniFrac beta diversity (P = 0.19) betweenC.difficile-positive and–negative calves. However, there was a significant difference in beta diversity as assessed using Bray-Curtiss diversity (P= 0.0077), andC.difficile-positive calves had significantly increased levels ofRuminococcus (gnavus group)(Adj.P= 0.052),Lachnoclostridium(Adj.P= 0.060),Butyricicoccus(Adj.P= 0.060), andClostridium sensu stricto 2compared toC.difficile-negative calves. Additionally,C.difficile-positive calves had fewer microbial co-occurrences thanC.difficile–negative calves, indicating reduced bacterial synergies. Thus, whileC.difficilecolonization alone is not associated with dysbiosis and is therefore unlikely to result in an increased likelihood of diarrhea in dairy calves, it may be associated with a more disrupted microbiota.
Assessing the reliability of automatic sentiment analysis tools on rating the sentiment of reviews of NHS dental practices in England
Authors: Byrne Matthew , O’Malley Lucy , Glenny Anne-Marie , Pretty Iain , Tickle Martin
Published: December 2021

Background

Online reviews may act as a rich source of data to assess the quality of dental practices. Assessing the content and sentiment of reviews on a large scale is time consuming and expensive. Automation of the process of assigning sentiment to big data samples of reviews may allow for reviews to be used as Patient Reported Experience Measures for primary care dentistry.

Aim

To assess the reliability of three different online sentiment analysis tools (Amazon Comprehend DetectSentiment API (ACDAPI), Google and Monkeylearn) at assessing the sentiment of reviews of dental practices working on National Health Service contracts in the United Kingdom.

Methods

A Python 3 script was used to mine 15800 reviews from 4803 unique dental practices on theNHS.ukwebsites between April 2018 –March 2019. A random sample of 270 reviews were rated by the three sentiment analysis tools. These reviews were rated by 3 blinded independent human reviewers and a pooled sentiment score was assigned. Kappa statistics and polychoric evalutaiton were used to assess the level of agreement. Disagreements between the automated and human reviewers were qualitatively assessed.

Results

There was good agreement between the sentiment assigned to reviews by the human reviews and ACDAPI (k = 0.660). The Google (k = 0.706) and Monkeylearn (k = 0.728) showed slightly better agreement at the expense of usability on a massive dataset. There were 33 disagreements in rating between ACDAPI and human reviewers, of which n = 16 were due to syntax errors, n = 10 were due to misappropriation of the strength of conflicting emotions and n = 7 were due to a lack of overtly emotive language in the text.

Conclusions

There is good agreement between the sentiment of an online review assigned by a group of humans and by cloud-based sentiment analysis. This may allow the use of automated sentiment analysis for quality assessment of dental service provision in the NHS.

The North American endemic genus Penstemon (Mitchell) has a recent geologic origin of ca. 3.6 million years ago (MYA) during the Pliocene/Pleistocene transition and has undergone a rapid adaptive evolutionary radiation with ca. 285 species of perennial forbs and sub-shrubs. Penstemon is divided into six subgenera occupying all North American habitats including the Arctic tundra, Central American tropical forests, alpine meadows, arid deserts, and temperate grasslands. Due to the rapid rate of diversification and speciation, previous phylogenetic studies using individual and concatenated chloroplast sequences have failed to resolve many polytomic clades. We investigated the efficacy of utilizing the plastid genomes (plastomes) of 29 species in the Lamiales order, including five newly sequenced Penstemon plastomes, for analyzing phylogenetic relationships and resolving problematic clades. We compared whole-plastome based phylogenies to phylogenies based on individual gene sequences (matK, ndhF, psaA, psbA, rbcL, rpoC2, and rps2) and concatenated sequences. We also We found that our whole-plastome based phylogeny had higher nodal support than all other phylogenies, which suggests that it provides greater accuracy in describing the hierarchal relationships among taxa as compared to other methods. We found that the genus Penstemon forms a monophyletic clade sister to, but separate from, the Old World taxa of the Plantaginaceae family included in our study. Our whole-plastome based phylogeny also supports the rearrangement of the Scrophulariaceae family and improves resolution of major clades and genera of the Lamiales.
Exploring anxiety awareness during academic science examinations
Authors: Apostolidis Hippokratis , Tsiatsos Thrasyvoulos
Published: December 2021

There is a developing interdisciplinary research field which has been trying to integrate results and expertise from various scientific areas, such as affective computing, pedagogical methodology and psychological appraisal theories, into learning environments. Moreover, anxiety recognition and regulation has attracted the interest of researchers as an important factor in the implementation of advanced learning environments. The present article explores the test anxiety and stress awareness of university students who are attending a science course during examinations. Real-time anxiety awareness as provided by biofeedback during science exams in an academic environment is shown to have a positive effect on the anxiety students experience and on their self-efficacy regarding examinations. Furthermore, the relevant research identifies a significant relationship between the students’ anxiety level and their performance. Finally, the current study indicates that the students’ anxiety awareness as provided by biofeedback is related to their performance, a relationship that is mediated and explained by the students’ anxiety.

Calímaco e a discussão sobre a poesia trágica
Authors: Junior Fernando Rodrigues
Published: December 2021

Embora o Suda atribua a Calímaco a composição de tragédias, a crítica moderna costuma ser cética quanto a essa informação, tendo em vista que suas supostas peças não chegaram até nós, bem como não foi preservado fragmento algum. O testemunho do Suda é posto em dúvida por conta da incompatibilidade entre a gravidade do gênero trágico e o conceito de poesia delgada defendido no Prólogo aos telquines. Calímaco menciona a tragédia em duas ocorrências no livro de Jambos, além de compor cinco epigramas nos quais discute a performance dramática nos festivais dionisíacos e a utilização das peças em contexto escolar. O presente artigo pretende investigar esses textos com o intuito de demonstrar que não haveria uma recusa de Calímaco à tragédia, mas rejeição a um estilo de composição considerado elevado e bombástico.

Cuatro poemas inéditos entre la correspondencia de Salvador Novo
Authors: González Morfín Juan
Published: December 2021

En este trabajo, se presentan cuatro poemas enviados a Salvador Novo por un joven poeta nayarita así como una carta que los acompañaba. De esta, se desprende que, aun sin conocer personalmente al autor, Novo se había venido convirtiendo en su tutor intelectual y guía de confianza. Los poemas tienen cierta calidad literaria, lo que permite pensar que fueron conservados no solamente por razones sentimentales, sino también por su contenido artístico. La presentación de estos, además de acercarnos a una faceta menos conocida de Novo, abre la posibilidad de rastrear la ulterior producción poética del que los envió, pero también invita a aprovechar más el enorme material existente en archivos con la correspondencia privada de este y otros autores.

The Significance of the Method in Theology
Authors: Moskałyk Jarosław
Published: December 2021

Reflection on the role of the method in theology aims to show that the method remains an extremely important tool for theology as a science. Theology, like other scientific disciplines, must be based on an appropriate methodological system when it undertakes to explain the religious and supernatural element in the world. Without this element, theology loses its significant cognitive value and ceases to inspire human thought. Today, one of the most important tasks of theology as a science is to establish the necessary balance between the deep sense of faith and religious practice.

These findings are important for determining whether the legislator should create a self-governing body of restructuring advisors, which should be a key element in establishing the principles of the profession. A direction of the discussion defined in such a way first requires a historical and legal analysis of the legislation relating to a bankruptcy administrator. This analysis culminates in a description of the process of transformation of the profession of a bankruptcy administrator into the profession of a restructuring advisor and an analysis of the current legislation, which allows determining the nature of the profession of restructuring advisor. The paper deals with the issues of how the professional self-government functions, and the ethics of the profession of restructuring adviser. It discusses the problems of currently operating organizations bringing together persons performing the profession of restructuring adviser, their status, and the validity of the legal acts issued by these entities.The above remarks on Polish legislation are contrasted with the legal situation in the Federal Republic of Germany to show the extent of the changes in this legislation in Poland over the last thirty years. In this article, attention is drawn to the need to enact additional legislation in this field in Poland. Future directions of the development of the profession of restructuring advisor as a profession of public trust are also evaluated through an analysis of both Polish constitutional law and European Union law, in particular,Directive 2019/1023 of the European Parliament and the Council relating to restructuring and bankruptcy.
Commercial immunoassays for detection of anti-SARS-CoV-2 spike and RBD antibodies: urgent call for validation against new and highly mutated variants
Authors: Lippi Giuseppe , Adeli Khosrow , Plebani Mario
Published: December 2021

Measuring the level of protection conferred by anti-SARS-CoV-2 (trimeric) spike or RBD (receptor binding domain) antibodies (especially total and IgG) is a suitable and reliable approach for predicting biological protection against the risk of infection and severe coronavirus disease 2019 (COVID-19) illness. Nonetheless, SARS-CoV-2 has undergone a broad process of recombination since the identification of the prototype lineage in 2019, introducing a huge number of mutations in its genome and generating a vast array of variants of interest (VoI) and concern (VoC). Many of such variants developed several mutations in spike protein and RBD, with the new Omicron (B.1.1.529) clade displaying over 30 changes, 15 of which concentrated in the RBD. Besides their impact on virus biology, as well as on the risk of detection failure with some molecular techniques (i.e., S gene dropout), recent evidence suggests that these mutations may also jeopardize the reliability of currently available commercial immunoassays for detecting anti-SARS-CoV-2 antibodies. The antigen (either spike or RBD) and epitopes of the prototype SARS-CoV-2 coated in some immunoassays may no longer reflect the sequence of circulating variants. On the other hand, anti-SARS-CoV-2 antibodies elicited by highly mutated SARS-CoV-2 variants may no longer be efficiently recognized by the currently available commercial immunoassays. Therefore, beside the compelling need to regularly re-evaluate and revalidate all commercially available immunoassays against live virus neutralization assays based on emerging VoCs or VoIs, diagnostic companies may also consider to redevelop their methods, replacing former SARS-CoV-2 antigens and epitopes with those of the new variants.

In this study, the effect of bacterial cellulose nanofibers (BCNF) incorporation on the structural and rheological properties of casein gels was investigated, where the mixed BCNF and casein gels were prepared by adding gluconic acid δ-lactone (GDL) to acidify the mixed polymer solutions at 3.0% casein concentration (w/v) and varying BCNF concentrations (0–0.5%, w/v). By changing the addition amount of GDL, the mechanical and structural properties of the mixed gels were studied at above, near and below the electric point (pI) of the casein. At pH above the pI of the casein, the introduction of BCNF initially increased the gel strength, but further addition of BCNF weakened the mixed gels. At near and below the pI of the casein, the incorporation of BCNF continuously increased the gel strength. Besides, all gels showed good structural homogeneity, without macroscopic phase separation occurring, which indicated good compatibility of BCNF with the casein gels.

Gestational diabetes mellitus (GDM) can have adverse effects on pregnancy. GDM is associated with changes in the lipid profile of pregnant women. Finding out the early ways to diagnose GDM can prevent the adverse outcomes. This meta-analysis study aimed to determine the effect of GDM on lipid profile. PubMed, ProQuest, Web of Science, Scopus, Science Direct, Google Scholar, and ClinicalTrial were systematically searched for published articles relating to GDM until 2021 according to PRISMA guidelines. Newcastle Ottawa scale was used to assess the quality of the studies. Thirty-three studies with a sample size of 23,792 met the criteria for entering the meta-analysis. Pooled standardized mean difference (SMD) for total cholesterol (TC) and triglyceride (TG) was 0.23 mg/dL (95% CI: 0.11–0.34) and 1.14 mg/dL (95% CI: 0.91–1.38), respectively. The mean of TC and TG in people with GDM was higher than that in normal pregnant women. A similar pattern was observed for the very low-density lipoprotein (VLDL) and TG/high-density lipoprotein (HDL) ratio, with pooled SMD of 0.99 mg (95% CI: 0.71–1.27) and 0.65 mg (95% CI: 0.36–0.94), respectively. Pooled SMD for HDL was −0.35 mg/dL (95% CI: −0.54 to −0.16), women with GDM had a mean HDL lower than normal pregnant women. Although pooled SMD was higher for low-density lipoprotein (LDL) in the GDM group, this difference was not significant (0.14 [95% CI: −0.04 to 0.32]). Of all the lipid profiles, the largest difference between the GDM and control groups was observed in TG (SMD: 1.14). Elevated serum TG had the strongest effect on GDM. Higher levels of TC, LDL, VLDL, and TG/HDL ratio, and lower level of HDL were exhibited in GDM group. So, these markers can be considered as a reliable marker in the diagnosis of GDM.
Nanostructured silica spin–orbit optics for modal vortex beam shaping
Authors: Coursault Delphine , Brasselet Etienne
Published: December 2021

Modality is a generic concept of wave-optics at the basis of optical information and communications. One of the challenges of photonics technologies based on optical orbital angular momentum consists in the production of a modal content for both the azimuthal and radial degrees of freedom. This basically requires shaping the complex amplitude of an incident light beam, which is usually made up from adaptive spatial light modulators or bespoke devices. Here, we report on the experimental attempt of a recent theoretical proposal [Opt. Lett.42, 1966 (2017)] toward the production of various optical vortex modes of the Laguerre–Gaussian type relying on the spin–orbit interaction of light. This is done in the visible domain from optical elements made out of silica glass. The idea consists in exploiting the combined effects of azimuthally-varying geometric phase with that of radially-varying propagation features. The proposed approach can be readily extended to any wavelength as well as to other families of optical modes, although some dynamic phase problems remain to be solved to make it a turnkey technology.

Any material when utilized for a required period of time and segment, the leftover residues of those materials are known as waste. Enormous waste is generated during such wear and tear process of materials depending on the usage and functions in a routine lifestyle. Those generated waste when overloaded beyond the capacity of natural recycling processes, would influence the environment and human health. Hence, the waste generated from used materials should be managed according to the environmental impact. Even though wastes are also sometimes rich in organic compounds, nutrients, and energy resources, they are not experimented and managed appropriately. Recently, different feasible techniques are invented and followed to recover and reuse the efficient resources that can create and support sustainable livelihood by creating green economy effects by reducing waste. In this chapter, the emphasis has been given to providing an overview of recent advancements on bio-based waste management and product recoveries such as microbes mediated approaches, biorefineries for waste valorization, and bioenergy from industrial waste.

Published: December 2021

In this work, a simple two-step method to create tunable self-assembled three-dimensional nanostructure array-like nanoantennas directly on the tip of an optical quartz glass fiber is described. The structures are prepared by using dry etching of the fiber tip. For the etching process, gold nanoparticles fabricated by thermal dewetting technique were used as template. The structures are applied as sensors for label-free analysis of organic substances in ppb range, such as drug residues in liquid solutions. The measurements are carried out by a portable Raman device with an exchangeable sensor head utilizing the SERS-effect. This method allows in situ applications. In order to characterize the SERS cells, para-thiocresol and diclofenac sodium are used as model substances. For optimization of the substrate performance, different thicknesses of the dewetting-layer (6, 9, 12 nm), different etching times for formation of the pillars (6, 8, 10 and 12 min), and different thicknesses of SERS-metallization (25, 50, 75 nm) of gold and silver are compared. In order to show the applicability of the structure on the tip of a fiber, measurements from the upper side and from the underside of the substrate on quartz plates are compared. Reproducible SERS enhancement factors up to
