Abstract

Objectives
Multiple pregnancies sustain the high pace of extreme prematurity. Little evidence is available about triplet gestation given the evolution in their management during the last decades. The aim of the study was to compare the neonatal outcomes of triplets with those of matched singletons in a cohort study.

Methods
An observational retrospective cohort study of triplets and matched singletons born between 2004 and 2017 matched by gestational age was conducted. Additionally, the investigation performed in regard to data from the overall Greek population of interest. The primary outcome was mortality or severe neonatal morbidity based on pregnancy type.

Results
A total of 237 triplets of 24–36 weeks’ gestation and 482 matched singletons were included. No differences in the primary outcome between triplets and singletons were found. Rates of severe neonatal morbidities did not differ significantly between triplets and singletons. A threshold of 1000 gr for birthweight and 28 weeks’ gestation for gestational age determined survival on triplets [OR: 0.08 (95% CI: 0.02–0.40, p=0.0020) and OR: 0.13 (95% CI: 0.03–0.57, p=0.0020) for gestational age and birthweight respectively]. In Greece stillbirths in triplets was 8 times higher than that of singletons (OR: 8.5, 95% CI: 6.9–10.5). From 3,375 triplets, 94 were stillborn, whereas in singletons, 4,659 out of 1,388,273. In our center 5 times more triplets than the expected average in Greece were delivered with no significant difference in stillbirths’ rates.

Conclusions
No significant differences were identified in mortality or major neonatal morbidities between triplets and matched singletons highlighting the significance of prematurity and birthweight for these outcomes.

Abstract
Gastric cancer treatment remains a major challenge because of its aggressiveness and spread. In this study, we developed a hydrogel system for the treatment of gastric cancer, which can kill tumor cells through photothermal action and drug treatment. Based on the formation of Schiff base linkage, the OSA/AHA/BP/PTX hydrogel was prepared by mixing oxidized sodium alginate (OSA), aminated hyaluronic acid (AHA), black phosphorus (BP), and paclitaxel (PTX) under physiological conditions, which exhibited excellent photothermal effect and slow release ability PTX. Moreover, CCK-8 and live/dead fluorescent confirmed that OSA/AHA/BP/PTX hydrogel could obvious inhibition the proliferation of gastric cancer cells (SGC7901). More importantly, in vivo experiments further show that the prepared hydrogel can significantly improve the tumor treatment effect of tumor-bearing mice by inducing tumor cell apoptosis and inhibiting the proliferation of new tumor cells. Compared with chemotherapy alone, photothermal combined chemotherapy had a better antitumor effect. The results of this study indicate that the composite hydrogel with controlled release of paclitaxel can be used as a candidate material for cancer treatment.

Abstract
A variety of modern super-resolution microscopy methods provide researchers with previously inconceivable biological sample imaging opportunities at a molecular resolution. All of these techniques excel at imaging samples that are close to the coverslip, however imaging at large depths remains a challenge due to aberrations caused by the sample, diminishing the resolution of the microscope. Originating in astro-imaging, the adaptive optics (AO) approach for wavefront shaping using a deformable mirror is gaining momentum in modern microscopy as a convenient approach for wavefront control. AO has the ability not only to correct aberrations but also enables engineering of the PSF shape, allowing localization of the emitter axial position over several microns. In this study, we demonstrate remote focusing as another AO benefit for super-resolution microscopy. We show the ability to record volumetric data (45 × 45 × 10 µm), while keeping the sample axially stabilized using a standard widefield setup with an adaptive optics addon. We processed the data with single-molecule localization routines and/or computed spatiotemporal correlations, demonstrating subdiffraction resolution.
Optical vortex lattice: an exploitation of orbital angular momentum
Authors: Zhu Liuhao , Tang Miaomiao , Li Hehe , Tai Yuping , Li Xinzhong 
Published: June 2021

Abstract
Generally, an optical vortex lattice (OVL) is generated via the superposition of two specific vortex beams. Thus far, OVL has been successfully employed to trap atoms via the dark cores. The topological charge (TC) on each optical vortex (OV) in the lattice is only ±1. Consequently, the orbital angular momentum (OAM) on the lattice is ignored. To expand the potential applications, it is necessary to rediscover and exploit OAM. Here we propose a novel high-order OVL (HO-OVL) that combines the phase multiplication and the arbitrary mode-controllable techniques. TC on each OV in the lattice is up to 51, which generates sufficient OAM to manipulate microparticles. Thereafter, the entire lattice can be modulated to desirable arbitrary modes. Finally, yeast cells are trapped and rotated by the proposed HO-OVL. To the best of our knowledge, this is the first realization of the complex motion of microparticles via OVL. Thus, this work successfully exploits OAM on OVL, thereby revealing potential applications in particle manipulation and optical tweezers.

AbstractThe disposal of non-biodegradable synthetic plastic wastes is linked with air, land, and marine pollutions. Incineration of plastic wastes released toxic substances into the air while recycled plastics end up accumulated in landfill and dumped into the ocean. In this study, novel sugar palm starch reinforced with sugar palm crystalline nanocellulose was blended with poly(lactic acid) (PLA) with various formulations to develop alternative materials potentially substituting conventional plastics. X-ray diffraction analysis demonstrated broad amorphous scattering background with minor diffraction peaks at 2θof 19.4° and 22° associated with VH-type and B-type crystal structure for all blend bionanocomposites samples. Higher solubility rates were observed for PLA20TPS80 (96.34%) and PLA40TPS60 (77.66%) associated with higher concentration of plasticizers providing extra space in the polymer chains to be penetrated by water molecules. Increasing PLA content was not necessarily enhancing the water vapor permeability rate. Dynamic mechanical analysis presented a significant increment in storage modulus (E′) for PLA60TPS40 (53.2%) compared to the trivial changes of PLA70TPS30 (10%) and PLA80TPS20 (0.6%). However, significant improvement in impact strength occurred only at PLA40TPS60 (33.13%), and further addition showed minor improvement between 12 and 20%. Overall, it is noted that PLA60TPS40 demonstrated adequate functional properties to be used in food packaging application.
Algorithmic Agency and Autonomy in Archaeological Practice
Authors: Huggett Jeremy 
Published: June 2021

AbstractA key development in archaeology is the increasing agency of the digital tools brought to bear on archaeological practice. Roles and tasks that were previously thought to be uncomputable are beginning to be digitalized, and the presumption that computerization is best suited to well-defined and restricted tasks is starting to break down. Many of these digital devices seek to reduce routinized and repetitive work in the office environment and in the field. Others incorporate data-driven methods to represent, store, and manipulate information in order to undertake tasks previously thought to be incapable of being automated. Still others substitute the human component in environments which would be otherwise be inaccessible or dangerous. Whichever applies, separately or in combination, such technologies are typically seen as black-boxing practice with often little or no human intervention beyond the allocation of their inputs and subsequent incorporation of their outputs in analyses. This paper addresses the implications of this shift to algorithmic automated practices for archaeology and asks whether there are limits to algorithmic agency within archaeology. In doing so, it highlights several challenges related to the relationship between archaeologists and their digital devices.

Abstract
The formation of third phase is a detrimental phenomenon witnessed in the nuclear separation processes during the extraction of certain metal salts by an organic solution, which comprises of a neutral extractant, tri-n-butyl phosphate dispersed in a non-polar diluent, n-dodecane (n-C12H26). In the present work, a comparative analysis on the third phase formation behaviour of three trialkyl phosphates, TBP, its linear and branched higher homologues tri-n-amyl phosphate and tris(2-methylbutyl) phosphate (T2MBP), respectively, have been provided which will be useful for the identification of an extractant with minimum third phase formation tendency. The organic phase splitting behaviour during the extraction of three mineral acids (HClO4, HCl and HNO3) and two tetravalent metal nitrates (Th(IV) and Zr(IV)) by trialkyl phosphates has been investigated to understand the influence of anionic and cationic components, respectively, in third phase formation of trialkyl phosphates. The effect of structure of the alkyl groups of trialkyl phosphate and chain length of diluents on third phase formation during Zr(IV) extraction from HNO3 media have also been studied. Overall, the third phase formation behaviour of T2MBP was found to be lower both for the extraction of mineral acid and Zr(IV), thereby indicating its potentiality for applications in various solvent extraction processes.
Modelling and forecasting stock volatility and return: a new approach based on quantile Rogers–Satchell volatility measure with asymmetric bilinear CARR model
Authors: Tan Shay Kee , Chan Jennifer So Kuen , Ng Kok Haur 
Published: June 2021

Abstract
This paper proposes quantile Rogers–Satchell (QRS) measure to ensure robustness to intraday extreme prices. We add an efficient term to correct the downward bias of Rogers–Satchell (RS) measure and provide scaling factors for different interquantile range levels to ensure unbiasedness of QRS. Simulation studies confirm the efficiency of QRS measure relative to the intraday squared returns and RS measures in the presence of extreme prices. To smooth out noises, QRS measures are fitted to the CARR model with different asymmetric mean functions and error distributions. By comparing to two realised volatility measures as proxies for the unobserved true volatility, results from Standard and Poor 500 and Dow Jones Industrial Average indices show that QRS estimates using asymmetric bilinear mean function provide the best in-sample model fit based on two robust loss functions with heavier penalty for under-prediction. These fitted volatilities are then incorporated into return models to capture the heteroskedasticity of returns. Model with a constant mean, Student-t errors and QRS estimates gives the best in-sample fit. Different value-at-risk (VaR) and conditional VaR forecasts are provided based on this best return model. Performance measures including Kupiec test for VaRs are evaluated to confirm the accuracy of the VaR forecasts.
Religiöse Musikalität in der Moderne – Max Weber
Authors: Bormuth Matthias 
Published: June 2021

ZusammenfassungMax Webers Rede, er sei „religiös unmusikalisch“, ist umstritten. Sie steht methodisch im Horizont seines Konzepts einer „wertfreien“ Wissenschaft, die auf der Annahme subjektiver Werte beruht, ohne welche keine Wissenschaft auskomme. Wertkonflikte und -diskussionen sind deshalb in der pluralisierten Moderne notwendig. Seine besondere, von Ambivalenzen geprägte Affinität zur Religion ist familiär und biografisch bedingt. In der späten Religionssoziologie betont Weber den Konflikt zwischen der erotischen und religiösen Sphäre, beeinflusst – wie sein ediertes Briefwerk zeigt – von lebensgeschichtlichen Erfahrungen.
Dental Caries in 12-Year-Old Schoolchildren who Participate in a Preventive and Restorative Dentistry Program
Authors: Ramírez Karol , Gómez-Fernández Adrián 
Published: June 2021

Since 2013, the Faculty of Dentistry of the University of Costa Rica has provided a preventive and restorative oral health program at Carmen Lyra Public School. The first generation of students that received dental care from this project were examined in 2019 for caries status. A total of 62 twelve-year-old schoolchildren were examined (31 boys and 31 girls). First, all teeth surfaces were cleaned with a brush and then rinsed. Subsequently, examination was performed in each person by a calibrated examiner using the International Caries Detection and Assessment System (ICDAS). Prevalence of dental caries was 59.7%. ICDAS code 2 was the most prevalent (68.8%), followed by 1 (19.3%), 5 (4.5%), 3 (3.5%), 6 (2.5%), and 4 (1.4%). Regarding number of carious surfaces, the highest prevalence was observed in the occlusal surfaces (77.3%), followed by the vestibular (13.9%), mesial (4.2%), palatal/lingual (4,1%) and distal (0.5%). Of these carious surfaces, 7% were caries associated with restorations and were present only on the occlusal surfaces. Boys had more cavities than girls (54.1% compared to 45.9%), however, this difference was not significant. Regarding the condition of restorations in teeth, 92 dental restorations (resin or amalgam) were found in the population studied and were well adjusted. Most of these restorations were found on the occlusal surfaces (82.6%), followed by vestibular surfaces (8.7%,) palatal/lingual (5.4%) surfaces, mesial surfaces (3.3%), and no restorations were detected on the distal surfaces. Sealants were identified in 11.3% schoolchildren; 98% were identified on the occlusal surfaces and the other 2% were found on the palatal/lingual surfaces. DMFT Index was 1.6±0.71. The prevalence of dental caries in this sample was low compared to other studies in twelve-year-old schoolchildren in Costa Rica. This may suggest that the oral health program had a positive impact in the studied population.

Abstract
Spiny coriander (Eryngium foetidum L.) is a perennial medicinal herb grown in the tropical regions worldwide. In India, it is used as a potential spice for garnishing and flavoring the dishes and treating several ailments. Eryngium spp. found in coastal Odisha, India has a strong aroma similar to the seasonal Coriandrum. The volatile flavor constituents of the unique plants were analyzed through headspace solid-phase microextraction (HS-SPME) using capillary gas chromatography (GC) and gas chromatography-tandem mass spectrometry (GC–MS/MS). The volatile compounds exhibited high chemodiversity, with 10-undecenal as the major component in leaves (44.98%) and branches (57.43%). Fourier-transform infrared (FTIR) spectroscopy identified eight major peaks grouped into six main regions. Chemo profiles of these two corianders were overlapped and showed similar area differences in the spectral peak. The lesser-known perennial Eryngium with high chemodiversity would be a better alternative to the seasonal coriander for aromatic, pharmaceutical, and industrial uses.
