Published: July 2022

Abstract
Background
The reproductive cycle of the recently described sponge Tethya meloni was investigated for a period of 15 months (September 2018 – November 2019) in the Mar Piccolo of Taranto (Southern Italy) and was compared with data previously collected for the other two sympatric species of the same genus known for Mediterranean Sea, T. citrina and T. aurantium.

Results
T. meloni is a gonochoric species with a sex ratio strongly shifted towards females. Asexual budding was a seasonal process, limited to few specimens. In a specimen collected in September 2018 both oocytes and buds occurred, suggesting that in T. meloni the sexual and asexual phases may coexist both at the population and individual levels.

Conclusions
The data obtained from this research compared with the available literature confirm the high temporal variability of the reproductive cycles in the Mediterranean species of Tethya, but with common general characteristics. In sexual reproduction, the oocyte production period lasts several months, with a peak between summer and autumn while spermatogenesis, shorter but with greater reproductive effort, follows the onset of oogenesis. The asexual reproduction phase of T. meloni, on the other hand, occurs in a short period and seems to have less importance in the overall reproductive process.

AbstractWith COVID-19 pandemic forcing academic institutions to shift to emergency remote teaching (ERT), teachers worldwide are attempting several strategies to engage their learners. Even though existing research in online learning suggests that effectiveness of the online session is more dependent on pedagogical design rather than technology feature, teachers may still focus on the intricacies of the technology. In this paper, we present the evolution of an active learning pedagogy, supported by technology (eBook reader—BookRoll, Analytics Dashboard—LAViEW), for an undergraduate physics classroom across a semester that was affected by the lockdown due to pandemic. The technology-enhanced pedagogy evolved in three phases—technology used in “Content Focus” mode, technology used in “Problem Focus” mode and technology used in “Learning Dialogue Focus” mode. The entire activities were designed and implemented within the technology-enhanced and evidence-based education and learning (TEEL) ecosystem, which supported integration of learning technologies with analytics system. Comparison of the student’s learning logs indicated that there was a sustained engagement in the learning activities conducted during the blended (before lockdown) and online mode (during lockdown). We had conducted one-way ANOVA to compare the post-test scores for each teaching phase and found statistically significant differences in the latter phases. A preliminary qualitative analysis of the learner artifacts generated as memos in BookRoll during each phase revealed that students were posing conceptual clarifications during the latter phases. These were also having greater alignment with the session agenda and showed construction of new knowledge based on the seed knowledge provided during the instructor–learner interaction sessions. The study provides key insights into how reflection and practice by both learner and teacher improves the acceptance of technology-enabled pedagogy.
Ultrastructural comparison and distribution of sensilla on male and female antennae of the sand fly Phlebotomus papatasi (Diptera: Psychodidae): the vector of cutaneous leishmaniasis in Egypt

Published: July 2022

Abstract
Background
Since sand flies are insects of medical importance and most of its sensilla were found on the antennae, the present investigation was designed to characterize the ultrastructure of the antennae of males and females and the sensilla distribution using scanning electron microscopy (SEM).

Results
The filiform antenna of males and females consisted of a scape, pedicel, and flagellum. Male antennae appeared longer than those of females and exhibited obvious sexual dimorphism. In addition to the microtrichiae, six cuticular sensillary types, namely trichoid, coeloconic (subtype the common grooved coeloconic), chaetic, campaniform, squamiform, and the basiconic, were identified. The trichoid sensilla occurred in five subtypes, namely long blunt-tipped trichoid, short sharp-tipped trichoid, short blunt-tipped trichoid, medium pointed-tipped trichoid, and apical trichoid. Little changes in the number and distribution pattern of same sensillar types between males and females were revealed. Trichoid sensilla were the most abundant of all sensillar types. The short sharp-tipped trichoid sensilla were observed on the pedicel of males, while in females they were found on both scape and pedicel. The position of the apical trichoid sensilla on the last flagellomere differs in males than in females.

Conclusions
The current study is the first to describe differences in the last three flagellomeres between males and females. Our results could provide a foundation for further research on sensory organs and approaches for the control of sand flies and enable for the use of new taxonomic characters to differentiate among species.
Superior mesenteric arteriovenous fistula embolization with a vascular plug for upper gastrointestinal hemorrhage: a case report
Authors: Shinagawa Austin , Billah Zaeem , Kansagra Kartik , Lam Cuong , Vatakencherry Geogy 
Published: July 2022

Abstract
Background
Superior mesenteric arteriovenous fistula is a rare vascular anomaly often presenting with sequelae of portal hypertension, heart failure, or mesenteric ischemia. This report describes a patient with a previously unidentified superior mesenteric arteriovenous fistula who presented with variceal bleeding, thought to be the leading cause of mortality associated with this condition. Although this patient was initially referred for a transjugular intrahepatic portosystemic shunt procedure, following a thorough review of her clinical history and imaging, she instead underwent embolization of the arteriovenous fistula likely responsible for her symptoms.

Case Presentation
A 75-year-old woman with a past surgical history of extensive small bowel resection presented with active variceal bleeding requiring transfusions. She was referred to vascular and interventional radiology for transjugular intrahepatic portosystemic shunt procedure; however, her clinical presentation was inconsistent with cirrhosis. This prompted a further review of her imaging, which identified a superior mesenteric arteriovenous fistula as the probable etiology of her varices. This fistula was subsequently embolized with a vascular plug and follow-up upper endoscopy at 1-month demonstrated complete resolution of her varices.

Conclusions
This report highlights a potential etiology of variceal bleeding in the acutely ill patient. Through a thorough consultation, the patient described here was able to avoid a procedure with the potential to cause catastrophic consequences, and instead receive the appropriate treatment for an uncommon condition.

Memories of a Gay Catholic Boyhood
Authors: D'Emilio John 
Published: July 2022

John D’Emilio is one of the leading historians of his generation and a pioneering figure in the field of LGBTQ history. At times his life has been seemingly at odds with his upbringing. How does a boy from an Italian immigrant family in which everyone unfailingly went to confession and Sunday Mass become a lapsed Catholic? How does a family who worshipped Senator Joseph McCarthy and supported Richard Nixon produce an antiwar activist and pacifist? How does a family in which the word divorce was never spoken raise a son who comes to explore the hidden gay sexual underworld of New York City?
Memories of a Gay Catholic Boyhood is D’Emilio’s coming-of-age story in which he takes readers from his working-class Bronx neighborhood to an elite Jesuit high school in Manhattan to Columbia University and the political and social upheavals of the late 1960s. He shares his personal experiences of growing up in a conservative, tight-knit, multigenerational family, how he went from considering entering the priesthood to losing his faith and coming to terms with his same-sex desires. Throughout, D’Emilio outlines his complicated relationship with his family while showing how his passion for activism influenced his decision to use research, writing, and teaching to build a strong LGBTQ movement.
This is not just John D’Emilio’s personal story; it opens a window into how the conformist baby boom decade of the 1950s transformed into the tumultuous years of radical social movements and widespread protest during the 1960s. It is the story of what happens when different cultures and values collide and the tensions and possibilities for personal discovery and growth that emerge. Intimate and honest, D’Emilio’s story will resonate with anyone who has had to chart their own path in a world they did not expect to find.

Published: July 2022

The mean wavelength, spectrum width, and optical power of the output light of an erbium-doped fiber source (EDFS) are key parameters for navigation systems based on navigation-grade and strategic-grade fiber optic gyroscopes (FOGs). We propose a method of simultaneous stabilization for EDFS parameters. The essence of this method is to stabilize the constant values of the mean wavelength and optical power by real-time adjustment of the two laser diodes’ pump ratios during temperature changes using an EDFS double-pass bidirectional optical scheme with the unpumped erbium-doped fiber. The achieved temperature stability of the EDFS mean wavelength as a component of the FOG was 0.32 ppm/°C, and the spectrum width at half-maximum was more than 16.5 nm.

Developing wide-angle, polarization-independent, and effective electromagnetic absorbers that endow devices with versatile characteristics in solar, terahertz, and microwave regimes is highly desired, yet it is still facing a theoretical challenge. Herein, a general and straightforward strategy is proposed to surmount the impedance mismatching in the ultrabroadband and wide-angle absorber design. A vertical atom sticking on

horizontal meta-atoms with conductive film is proposed as the functional motif, exhibiting the strong ohmic dissipation along both vertical and horizontal directions. Assisted by the intelligent optimization strategy, the structure dimension, location, and film distribution are designed to maintain absorbing performance under different incident angles. As a demonstration, an absorber was designed and proved in both simulation and experiment. Significantly, the over 10 dB absorption from 5 to 34 GHz is achieved in the range of 0° to 70° for both TE and TM, and even 3 to 40 GHz from 60° to 70° for the TE wave. Meanwhile, the proposed multidimensional design of functional motifs can be attached with optical transparency function at will. That is to say, our effort provides an effective scheme for expanding matching area and may also be made in optical, infrared, and terahertz regimes.

Published: July 2022

Background
Among comatose survivors of out-of-hospital cardiac arrest (OHCA), targeted temperature management (TTM) has improved neurological outcomes. However, although the target temperature shifted from 33°C to 33°C~36°C, the optimal target temperature is still unclear. The goal of this study was to evaluate neurological outcomes at 6 months at target temperatures of 33°C and 36°C.

Materials and methods
We analyzed OHCA survivors who underwent TTM and were recorded in the Korean Hypothermia Network, a prospective multicenter registry, from October 2015 to December 2018. The primary outcome was good neurological outcome at six months, defined as a cerebral performance category of 1–2, and the secondary outcome was survival at 6 months.

Results
A total of 1339 patients were treated with TTM in twenty-two emergency departments. Of those, 1054 were treated at 33°C, and 285 were treated at 36°C. There was no significant difference in good neurological outcomes at 6 months (30.6% vs. 31.2%, p = 0.850, adjusted OR 0.97, 95% CI = 0.73–1.29]) and survival at six months (41.4% vs. 38.7%, p = 0.401, adjusted HR 1.08, 95% CI = 0.91–1.28]) between TTM 33°C and TTM 36°C. After propensity score matching, good neurological outcomes at 6 months (OR 0.93, 95% CI = 0.74–1.18) and survival at 6 months (HR 1.05, 95% CI = 0.92–1.21) were still not associated with TTM 33°C and TTM 36°C.

Conclusion
In this study, patients treated with a target temperature of 33°C had similar good neurological outcomes and survival at six months compared with those treated with a target temperature of 36°C.
Cost effectiveness of temporary isolation rooms in acute care settings in Singapore
Authors: Graves Nicholas , Cai Yiying , Mitchell Brett , Fisher Dale , Kiernan Martin 
Published: July 2022

Objectives
To estimate the change to health service costs and health benefits from a decision to adopt temporary isolation rooms that are effective at isolating the patient within a general ward environment. We assess the cost-effectiveness of a decision to adopt an existing temporary isolation room in a Singapore setting.

Method
We performed a model-based cost-effectiveness analysis to evaluate the impact of a decision to adopt temporary isolation rooms for infection prevention. We estimated changes to the costs from implementation, the number of cases of healthcare associated infection, acute care bed days used, they money value of bed days, the number of deaths, and the expected change to life years. We report the probability that adoption was cost-effective by the cost by life year gained, against a relevant threshold. Uncertainty is addressed with probabilistic sensitivity analysis and the findings are tested with plausible scenarios for the effectiveness of the intervention.

Results
We predict 478 fewer cases of HAI per 100,000 occupied bed days from a decision to adopt temporary isolation rooms. This will result in cost savings of $SGD329,432 and there are 1,754 life years gained. When the effectiveness of the intervention is set at 1% of cases of HAI prevented the incremental cost per life year saved is $16,519; below the threshold chosen for cost-effectiveness in Singapore.

Conclusions
We provide some evidence that adoption of a temporary isolation room is cost-effective for Singapore acute care hospitals. It is plausible that adoption is a positive decision for other countries in the region who may demonstrate fewer resources for infection prevention and control.

Published: July 2022

El presente estudio tiene como objetivo validar una escala para evaluar la satisfacción y el compromiso laboral organizativo en los empleados del servicio hotelero del Ecuador. Para ello empleó el Análisis Factorial Confirmatorio con el Software AMOS IBM. El estudio se realizó en una muestra de 914 empleados del sector hotelero de las tres ciudades principales del Ecuador: Quito, Guayaquil y Cuenca. Los índices de ajuste (χ2, GFI, CFI, AGFI, IFI, TLI, NFI χ2/DF y AIC) permiten abordar la problemática de la satisfacción y el compromiso organizativo mediante seis dimensiones. Estas dimensiones son: satisfacción con las actividades, satisfacción con las gratificaciones, satisfacción con el desarrollo profesional, implicación laboral, orgullo laboral y desilusión laboral. Se comprueba que el instrumento es válido y fiable con esta dimensionalidad. Se discute la posibilidad de agrupar las tres primeras dimensiones como si fuesen variables endógenas en la variable satisfacción, mientras que los cuatro restantes pueden agruparse como variables endógenas en la variable compromiso organizativo.
Existence of solutions to contact mean-field games of first order
Authors: Hu Xiaotian , Wang Kaizhi 
Published: July 2022

Abstract
This paper deals with the existence of solutions of a class of contact mean-field game systems of first order consisting of a contact Hamilton-Jacobi equation and a continuity equation. Evans found a connection between Hamilton-Jacobi equations and continuity equations from the weak KAM point of view, where the coupling term is zero. Inspired by his work, we prove the main existence result by analyzing the properties of the Mather set for contact Hamiltonian systems.

Abstract
In this article, we introduce and study the notion of Krull dimension for C*-algebras. We show that every C*-algebra with Krull dimension contains an essential ideal that is a finite direct sum of critical ideals. We show that a C*-algebra with Krull dimension has finite-dimensional center, and conclude that every graph C*-algebra with Krull dimension has real rank zero, and is

Influences of pre-bending load and corrosion degree of reinforcement on the loading capacity of concrete beams
Authors: Tran The Truyen , Tran Thu Minh , Nguyen Xuan Tung , Nguyen Duc Hieu , Vu Ba Thanh , Vo Van Nam 
Published: July 2022

AbstractIn this article, experimental studies on the flexural behavior of concrete beams with corroded reinforcement were conducted. The beams were subjected to simultaneous different load levels and immersed in NaCl solution for 30 days with accelerated corrosion. A four-point bending test was subsequently carried out to determine the loading capacity of these beams. Experimental data show that the loading capacity of the beam decreases as the level of preload increases. The mass loss of steel bars in the beams increases as the level of preload increases. The loading capacity and steel mass loss of the beams subjected to 0.8 of failure load of the non-corroded beam decrease by 32.7 and 30.3%, respectively. The numerical investigation was also done to evaluate the loading capacity with various corrosion degrees of steel bars.

Authors: Mardalena Ida , Sutejo Sutejo , Suryani Eko 
Published: July 2022

Background: Severe postpartum anemia after cesarean is strongly associated with predelivery and postpartum Hb levels in maternal. The adverse effects of anemia impact health and economic development. WHO estimates that 12.8% of maternal deaths in Asia can be attributed to anemia.Objective: This study aims to identify the effect of the anemia booklet on the perception, participation, and hemoglobin level of cesarean mothers in the management of anemia.Method: This quasi-experiment with the pre-posttest without control groups design was conducted to measure the effectiveness of education using a nutrition booklet on the level of Haemoglobin and perception variable. 30 respondents were involved, and the data analysis was carried out using a Statistical test using paired t-test with a CI of 95%.Result: The relationship between Hb before and after giving the booklet was revealed with a correlation coefficient of 0.333 and a significance of 0.84 (p-value 0.05). Perceptions before and after understanding the booklet obtained p-value = 0.000 0.05. Management before and after giving the booklet obtained p-value = 0.005 0.05. The interviews found that after receiving information, mothers' perceptions improved regarding understanding anemia, recognizing signs and symptoms, preventing anemia, consuming protein, consuming drinks, and good nutrition for anemia management. After giving anemia management communication through booklets, there was an increase in the mother's participation in consuming snacks, drinking after mealtime, and improving personal and environmental hygiene.Conclusion: Education through booklets affected maternal perceptions and management actions in preventing anemia but did not affect hemoglobin (Hb). It could also increase mothers' perception and participation in consuming snacks, drinking after mealtimes, and personal and environmental hygiene. Furthermore, nurses could use booklets as a medium of counseling.
