Stationary and Non-stationary Temperature-Duration-Frequency Curves for Australia
Authors: Laz Orpita U , Rahman Ataur , Ouarda Taha B M J , Jahan Nasreen
Published: April 2023

Australian summer heat events have become more frequent and severe in recent times. Temperature-duration-frequency (TDF) curves connect the severity of heat episodes of various durations to their frequencies and thus can be an effective tool for analysing the heat extremes. This study examines Australian heat events using data from 82 meteorological stations. TDF curves have been developed under stationary and non-stationary conditions. Generalised Extreme Value (GEV) distribution is considered to estimate extreme temperatures for return periods of 2, 5, 10, 25, 50 and 100 years. Three major climate drivers for Australia have been considered as potential covariates along with Time to develop the non-stationary TDF curves. According to the Akaike information criterion, the non-stationary framework for TDF modelling provides a better fit to the data than its stationary equivalent. The findings can be beneficial in offering new information to aid climate adaptation and mitigation at the regional level in Australia.
Phosphate-solubilizing fungi in riparian sediment of Xiangxi Bay (China) and implications of phosphorus pollution control
Authors: Chen Guohuo , You Song
Published: April 2023

The implementation of the Three Gorges Project (Yangtze River, China) has caused severe eutrophication in Xiangxi Bay (XXB). Although several studies have investigated the mechanism of eutrophication in physical and chemical fields, biological factors were neglected. Discarded food, phosphate rock mining, and transportation result in the nutrient input to XXB. To better understand the aquatic eutrophication in XXB, we screened phosphate-solubilizing fungi (PSF) from XXB riparian sediments and studied the factors influencing PSF activities. It was observed that (1) PSF was present in all seven sampling sites, (2) strains ofPenicilliumsp. XXR-A andAspergillussp. XXR-B1 exhibited higher phosphorus release thanTalaromycessp. XXR-F andTalaromycessp. XXR-D, and (3)Aspergillus. sp. XXR-B1 could solubilize phosphate rock efficiently, and some substances derived from discarded food could influence its phosphorus-release activity. Based on this study, we suggest the following: a) covering the phosphate rock piles on wharves could reduce the inflow of phosphate rock powder into XXB with rainwater, which is a simple and emerging strategy; b) prevention of the discharge of food waste into XXB can abate the nutrient supply for PSF and c) decrease of nitrogen content (especially NO3–-N) can influence on the behavior of PSF. Moreover, PSF may be an active participant during XXB eutrophication. Furthermore, nutrient conditions play an important role in regulating the phosphorus-release activity of PSF.

The pyjama shark (Poroderma africanum) is a Scyliorhinid species endemic to South Africa. Even though it is kept in captivity in many aquariums, there is a lack of research on its growth and development. In this study, we investigated the fertilization rate of eggs, growth, and age at female sexual maturation in captive pyjama sharks, and compared their growth to that of wild individuals. The fertilization rate of 319 eggs was 18.8%, and total length (Lt) and body weight (Wt) at hatching were 14.65 ± 0.26 cm and 16.6 ± 0.8 g, respectively. Both in captivity and in the wild, males showed negative allometric growth and females showed isometric growth. The growth performance (Φ') was also greater in captive sharks compared to wild sharks regardless of sex. One female laid fertilized eggs (85.2 cm Lt and 3300 g Wt at laying) 2419 days (6.6 years) after hatching and was considered sexually mature. It was suggested that the difference in growth was due to the difference in habitat depth preference between males and females. This is the first study to compare the growth of captive and wild catsharks as well as the first study to compare growth in male and female pyjama sharks. Therefore, this study provides a greater insight into the effects of captivity on different elasmobranch families, as well as aiming to inform differential husbandry techniques depending on sex.

Authors: Anwar Zahid , Muhammad
Published: April 2023

The agricultural wastes are used for production of vital enzymes like cellulase, protease and lipase through Solid State Fermentation (SSF) which reveal their industrial potential aspect. This study was done to find out the ability of Rhizopus oryzae to produce lipase, protease and cellulase through SSF. Wheat bran showed maximum enzyme activities as related to others agricultural wastes. The enzymes showed maximum activities (21.4 ± 0.04) (4.6 ± 0.02 IU/mL) and (1.1 ± 0.01 IU/mL) for cellulase, lipase and protease respectively at temperature 25ºC and incubation period 72 hours. Response surface methodology (RSM) used to optimize conditions likes temperature, pH, moisture contents, inoculum size and substrate concentration. RSM revealed maximum enzyme activities using 100% moisture contents, temperature 25ºC, pH 5, substrate concentrations 12g and inoculum size of 6 mL. The method of ammonia sulphate precipitation used for the purification and crystallization of enzymes like lipase, protease and cellulase. The precipitation of cellulase, lipase and protease performed with 80%, 70% and 90% ammonium sulphate concentrations to increase yield. The characterization of lipase, protease, cellulase revealed that it worked best below acidic conditions (pH 5) and at moderate temperature (25ºC). The results revealed that the mold oryzae had potential to produce industrially important enzymes at acidic pH.
Extending the toolbox for RNA biology with SegModTeX: A polymerase-driven method for site-specific and segmental labeling of RNA
Authors: Haslecker Raphael , Pham Vincent , Glänzer David , Kreutz Christoph , Dayie Theodore , D'Souza Victoria
Published: April 2023

RNA performs a wide range of functions regulated by its structure, dynamics, and often post-transcriptional modifications. While NMR is the leading method for understanding RNA structure and dynamics, it is currently limited by the inability to reduce spectral crowding by efficient segmental labeling. Furthermore, because of the challenging nature of RNA chemistry, the tools being developed to introduce site- specific modifications are increasingly complex and laborious. Here we use a previously designed Tgo DNA polymerase mutant to present SegModTeX — a versatile, one-pot, copy-and-paste approach to address these challenges. By precise, stepwise construction of a diverse set of RNA molecules, we demonstrate the technique to be superior to RNA polymerase driven and ligation methods owing to its substantially high yield, fidelity, and selectivity. We also show the technique to be useful for incorporating fluorescent- and a wide range of other probes, which significantly extends the toolbox of RNA biology in general.
Optimizing the performance of microwave photonic signal processors based on Kerr microcombs
Authors: Moss David J.
Published: April 2023

Microwave photonic (MWP) transversal signal processors offer a compelling solution for realizing versatile high-speed information processing by combining the advantages of reconfigurable electrical digital signal processing and high-bandwidth photonic processing. With the capability of generating a number of discrete wavelengths from micro-scale resonators, optical microcombs are powerful multi-wavelength sources for implementing MWP transversal signal processors with significantly reduced size, power consumption, and complexity. By using microcomb-based MWP transversal signal processors, a diverse range of signal processing functions have been demonstrated recently. In this paper we provide a detailed analysis for the errors induced by experimental imperfections processors. First, we investigate the errors arising from different sources including imperfections in the microcombs, the chirp of electro-optic modulators, chromatic dispersion of the dispersive module, shaping errors of the optical spectral shapers, and noise of the photodetector. Next, we provide a global picture quantifying the impact of error sources on the overall system performance. Finally, we introduce feedback control to compensate the errors caused by experimental imperfections, achieving significantly improved accuracy. These results provide a guide for optimizing the accuracy of microcomb-based MWP transversal signal processors.
The numerical investigation of spindle torque for a controllable pitch propeller in feathering maneuver
Authors:   Department of Naval Architecture and Marine Engineering, Yildiz Technical University, 34349, Istanbul, Turkiye, Yurtseven Ahmet , Aktay Kaan
Published: April 2023

Present paper studies the variation of the blade spindle torque in a controllable pitch propeller (CPP) during the feathering maneuver, which is one of the rare but most challenging propeller maneuvers in CPP operation. The knowledge of the spindle torque under different operating conditions is one of the key features for the CPP controller unit design. The aim of this study is determining the forces needed to be governed to control the blade motion of a CPP converted from a fixed pitch propeller and the scale effect on these forces. So as to obtain a realistic numerical setup, the time-dependent superposed motion of the main rotation of the propeller and the rotation of each blade around its axis is modeled using a hybrid overset/sliding mesh technique. The spindle torque values were calculated during the dynamical variation of the blade pitch in feathering maneuver, and a novel expression is recommended to non-dimensionalize the predicted spindle torque. The result revealed that the required torque values to rotate each blade during the propeller maneuver is rising up to a critical pitch angle. Further increment of the pitch angle results in lower spindle torque values. Furthermore, this critical pitch angle is inversely proportional to the propeller loading.
Modified magnetite and hydrothermal apatite in banded iron-formations and implications for high-grade Fe mineralization during retrogressive metamorphism
Authors: Shi Kangxing , Wang Changming , Bagas Leon , Duan Hongyu
Published: April 2023

Modified magnetite and hydrothermal apatite in banded iron formations (BIFs) are ideal minerals for studying hydrothermal and metamorphic processes and are applied to linking with high-grade Fe mineralization and metamorphism in iron deposits hosted by BIFs. In this study, we have investigated the geochemical composition of modified magnetite and hydrothermal apatite and in situ U-Pb geochronology on apatite from the Huogezhuang BIF-hosted Fe deposit in northeastern China. The magnetite in metamorphosed BIF is modified, locally fragmented, and forms millimeter-to micrometer-scale bands. The apatite is present surrounding or intergrowing with magnetite, has corroded surfaces, and contains irregular impurities and fluid inclusions, indicating that it has been partly hydrothermally altered. Original element compositions (e.g., Fe, Al, Ti, K, Mg, and Mn) of magnetite in BIFs have been modified during high-grade Fe mineralization and retrogressive metamorphism with temperature reduction and addition of acids. The hydrothermally altered apatite has been relatively reduced in the contents of Ca, P, F, La, Ce, Nd, δCe, δEu, and total REEs compared to non-altered apatite. The magnetite and apatite in low-grade BIFs are poorer in FeOT than those from the high-grade Fe ores, indicating that Fe is remobilized during the transition from BIFs to high-grade Fe ores. The magnetite and apatite in high-grade Fe ores are overgrown by greenschist-facies minerals formed during retrograde metamorphism, suggesting that the high-grade Fe mineralization may be related to retrogressive metamorphism. In situ U-Pb geochronology of apatite intergrown with magnetite and zircon LAICP-MS U-Pb dating at Huogezhuang deposit reveals that the BIF-hosted magnetite was altered and remobilized at ca. 1950–1900 Ma, and deposition of the BIF began during the Late Neoarchean. The changes of elements in the modified magnetite and different geochemical compositions of the altered and unaltered apatite confirm that the modified magnetite and hydrothermal apatite can be effective in tracing high-grade Fe mineralization and retrogressive metamorphism in BIFs.
Are Indonesian construction companies financially distressed? A prediction using artificial neural networks
Authors: Titik Kristanti Farida , Safriza Zahra , Fitrizal Salim Dwi
Published: April 2023

Construction companies are very dependent on the projects carried out by a company. Therefore, measuring whether a company is distressed or non-distressed can be done by looking at the ratios derived from the components of the financial statements from both the balance sheet and the company’s profit and loss. This study offers a new method for measuring financial distress in companies with Artificial Neural Networks (ANN). The model provided comes from several financial ratios in 17 construction companies listed on the Indonesia Stock Exchange. The model is expected to produce the best model by showing the lowest prediction error rate. The results showed that the best ANN model has 25 inputs, 20 hidden layer neurons, and 1 best model output. The model obtained will be tested directly on the sample used; the results are that 6 construction companies in Indonesia have financial distress and 11 non-distress problems. This result proves that the best model obtained can predict the level of financial distress of companies with a small error rate to produce 6 companies identified as financially distressed. This result can be a warning for companies to increase revenue by adding new projects to get out of financial distress status. Traditional financial distress models such as Altman, Zmijewski, Springate, and Fulmer, which have become researchers’ guidelines for measuring financial distress, can be added to the ANN 25-20-1 model as a comparison to strengthen the research results.

Authors: A. Bharath , Maddamsetty Ramesh , Pawar Uttam
Published: April 2023

Drainage morphometric analysis is very substantial in determining the characteristics of a river basin. It is performed through spatial analysis, which helps study the various hydrological interactions and responses in the watershed. In this research, the authors have tried to study the geomorphological scenario of the Shimsha River basin using the remote sensed data, toposheets, and geographic information systems tools. In the current study, linear, aerial, and relief parameters are derived and analysed to evaluate the runoff and erosion characteristics of the basin. The stream pattern of the Shimsha River is mostly dendritic with a sixth-order stream and a drainage density of 0.56 km/km2. According to the morphometric characteristics, the study area appears to be in the equilibrium stage of development, slightly elongated, with moderate to low flow rates and reduced sensitivity to erosion. The hypsometric curve and hypsometric integral value of the Shimsha River basin show the mature phase of the geomorphic evolution of the basin and imply that runoff will be moderate to high. The asymmetry factor of the Shimsha River basin is 49.3, which specifies that the basin is slightly tilted towards the right. The study's results clarify the phenomena of runoff and erosion, which is crucial for watershed management initiatives.

Oxidative DNA Damage-induced PARP-1-mediated Autophagic Flux
Disruption Contributes to Bupivacaine-induced Neurotoxicity During
Pregnancy
Authors: Luo Jiaming , Zeng Lei , Li Ji , Xu Shiyuan , Zhao Wei
Published: April 2023

Objective:

Severe neurologic complications after spinal anesthesia are rare but highly distressing,
especially in pregnant women. Bupivacaine is widely used in spinal anesthesia, but its neurotoxic
effects have gained attention.

Methods:

Furthermore, the etiology of bupivacaine-mediated neurotoxicity in obstetric patients remains
unclear. Female C57BL/6 mice were intrathecally injected with 0.75% bupivacaine on the 18th
day of pregnancy. We used immunohistochemistry to examine DNA damage after bupivacaine treatment
in pregnant mice and measured γ-H2AX (Ser139) and 8-OHdG in the spinal cord. A PARP-1 inhibitor
(PJ34) and autophagy inhibitor (3-MA) were administered with bupivacaine in pregnant mice.
Parp-1flox/flox mice were crossed with Nes-Cre transgenic mice to obtain neuronal conditional knockdown
mice. Then, LC3B and P62 staining were performed to evaluate autophagic flux in the spinal
cords of pregnant wild-type (WT) and Parp-1-/- mice. We performed transmission electron microscopy
(TEM) to evaluate autophagosomes.

Results:

The present study showed that oxidative stress-mediated DNA damage and neuronal injury
were increased after bupivacaine treatment in the spinal cords of pregnant mice. Moreover, PARP-1
was significantly activated, and autophagic flux was disrupted. Further studies revealed that PARP-1
knockdown and autophagy inhibitors could alleviate bupivacaine-mediated neurotoxicity in pregnant
mice.

Conclusion:

Bupivacaine may cause neuronal DNA damage and PARP-1 activation in pregnant mice.
PARP-1 further obstructed autophagic flux and ultimately led to neurotoxicity.

Authors: Suzuki Mai , Yamanaka Kou , Fukushima Shinichi , Ogawa Mayu , Nagaiwa Yuki , Naito Toshio
Published: April 2023

Background

The continuity of care between hospital visits conducted through mobile apps creates new opportunities for people living with HIV in situations where face-to-face interventions are difficult.

Objective

This study investigated the user experience of a mobile medication support app and its impact on improving antiretroviral therapy compliance and facilitating teleconsultations between people living with HIV and medical staff.

Methods

Two clinics in Japan were invited to participate in a 12-week trial of the medication support app between July 27, 2018, and March 31, 2021. Medication compliance was assessed based on responses to scheduled medication reminders; users, including people living with HIV and medical staff, were asked to complete an in-app satisfaction survey to rate their level of satisfaction with the app and its specific features on a 5-point Likert scale.

Results

A total of 10 people living with HIV and 11 medical staff were included in this study. During the trial, the medication compliance rate was 90%, and the mean response rates to symptom and medication alerts were 73% and 76%, respectively. Overall, people living with HIV and medical staff were satisfied with the medication support app (agreement rate: mean 81% and 65%, respectively). Over 80% of medical staff and people living with HIV were satisfied with the ability to record medications taken (9/11 and 8/10 medical staff and people living with HIV, respectively), record symptoms of concern (10/11 and 8/10),and inquire about drug combinations (8/10, 10/10). And further, 90% of people living with HIV were satisfied with the function for communication with medical staff (9/10).

Conclusions

Our preliminary results demonstrate the feasibility of the medication support app in improving medication compliance and enhancing communication between people living with HIV and medical staff.

Authors: Smail Emily J , Livingston Torie , Wolach Adam , Cenko Erta , Kaufmann Christopher N , Manini Todd M
Published: April 2023

Background

During the COVID-19 pandemic, media sources dedicated significant time and resources to improve knowledge of COVID-19 precautionary behaviors (eg, wearing a mask). Many older adults report using the television, radio, print newspapers, or web-based sources to get information on political news, yet little is known about whether consuming news in the early phase of the pandemic led to behavior change, particularly in older adults.

Objective

The goals of this study were to determine (1) whether dosage of news consumption on the COVID-19 pandemic was associated with COVID-19 precautionary behaviors; (2) whether being an ever-user of social media was associated with engagement in COVID-19 precautionary behaviors; and (3) among social media users, whether change in social media use during the early stages of the pandemic was associated with engagement in COVID-19 precautionary behaviors.

Methods

Data were obtained from a University of Florida–administered study conducted in May and June of 2020. Linear regression models were used to assess the association between traditional news and social media use on COVID-19 precautionary behaviors (eg, mask wearing, hand washing, and social distancing behaviors). Analyses were adjusted for demographic characteristics, including age, sex, marital status, and education level.

Results

In a sample of 1082 older adults (mean age 73, IQR 68-78 years; 615/1082, 56.8% female), reporting 0 and <1 hour per day of media consumption, relative to >3 hours per day, was associated with lower engagement in COVID-19 precautionary behaviors in models adjusted for demographic characteristics (β=–2.00; P<.001 and β=–.41; P=.01, respectively). In addition, increasing social media use (relative to unchanged use) was associated with engagement in more COVID-19 precautionary behaviors (β=.70, P<.001). No associations were found between being an ever-user of social media and engaging in COVID-19 precautionary behaviors.

Conclusions

The results demonstrated an association between higher media consumption and greater engagement in COVID-19 precautionary behaviors in older adults. These findings suggest that media can be effectively used as a public health tool for communication of prevention strategies and best practices during future health threats, even among populations who are historically less engaged in certain types of media.

Authors: Nikolajski Cara , O'Brien Julia , Nardo Emily , Szigethy Eva , Jonassaint Charles
Published: April 2023

BACKGROUND

Depression and other mental health disorders are prevalent among people living with chronic health conditions. Although digital cognitive behavioral therapy (CBT) is considered an effective treatment, African American individuals are less likely to engage in and adhere to digital therapies for mental health disorders compared with White individuals.

OBJECTIVE

The aim of this study was to understand digital CBT mental health treatment perceptions and preferences of African American individuals with sickle cell disease (SCD).

METHODS

African American individuals with SCD from various US locations were invited to participate in a series of focus groups. Participants were introduced to a health coach–supported mental health app and then asked a series of questions about the usability and appeal of the program as well as, more generally, what would make a digital mental health program effective for them. The authors reviewed the focus group transcripts and conducted a qualitative analysis of the results.

RESULTS

A total of 25 people participated in 5 focus groups. Overall, 5 primary themes emerged regarding how app content and related coaching could be modified to enhance digital CBT engagement. These themes included connection with others living with SCD, the personalization of app content and coaching, characteristics of coaches, journaling and pain tracking, and considerations for optimal engagement.

CONCLUSIONS

Enhancing the user experience by making digital CBT tools relevant to patient populations is critical for optimizing program engagement and its uptake. Our findings highlight potential strategies to modify and design digital CBT tools for users with SCD and may also be applicable to patients with other chronic conditions.

Abstract: Liquefied petroleum gas (LPG) is commonly used in hotels and homes for all cooking purposes. Furthermore, despite the fact that many explosions have occurred as a result of LPG outflow, it is very user friendly to all users. We have implemented a module in our system to address these societal issues. In this system that includes a gas sensor to detect gas outflow. If the sensor detects the level of gas outflow and compares it to the threshold value previously set in the software. If it exceeds the fixed threshold value, the buzzer activates and the relay connected to the circuit turns on. The entire power supply will then be turned off. People nowadays are unaware of their daily gas usage, which causes a delay in refilling the LPG cylinder. To overcome such difficulties, our system has one more module. The load sensor is used to continuously monitor the gas level. The load cell's output is connected to the microcontroller. The microcontroller manipulates the data so that the weight of the gas cylinder, the level of gas leakage, and the amount of gas used per day are displayed on the LCD. If the gas cylinder's level falls dangerously low, a new cylinder is automatically booked and the status is transmitted to the user via the Wi-Fi module
The Function of Local Government in Public Policy Evaluation Networked Modern Stores in Banjarmasin City

Published: April 2023

The presence of modern networked stores in the city of Banjarmasin causes traditional business actors to feel marginalized. The distance between establishments is such close operational times that are not following regulations, as well as partnerships and discourses on a moratorium on the establishment, are the causes of the underlying policies that have not run optimally. The purpose of this study is to explore and analyze policy evaluation through the role of actors, especially the Government, in protecting the existence of small-scale business actors behind the strong capitalist economic flows represented by modern networked stores. Indicators of the role of policies become new knowledge spaces in policy evaluation studies that will provide practical benefits for the Government in seeing the natural policy conditions behind the evaluation process, which is often carried out in formal conditions. This study uses a case study method with a qualitative research approach. The results show that policy evaluation is still not effective though the Regional Government as a critical actor has played its role in maintaining policy consistency so that competition between large investors represented through modern networked shops and small investors represented by micro, small and medium enterprises, and traders runs healthily. This paper argues that a consistent public policy will impact achieving the goals and objectives of the policy, only that an economic system based on capital, motives, and interests is another factor that influences the course of a evaluation public policy.

Published: April 2023

The purpose of this study is to examine how to enhance the critical thinking of young people through digital literacy skills. Furthermore, the ability to think critically is seen from the perspective of building active participation in general elections in Indonesia. A literature review was used as the research approach in this study.  The results show that based on the challenges of digital life, the younger generation falls into two categories: objects and subjects in general elections. The dominant key to the success of digital literacy lies in the ownership of digital literacy skills, more specifically leading to critical thinking in responding to all events in the general election phenomenon in Indonesia. The design of the digital literacy-based democracy movement includes viral party centers, online forums, digital party organizations, online campaigns, and online protests. Critical thinking in generating active participation in elections includes several elements: digital skills, ethics, safety, and culture. So that the output of active participation is in the form of supporting general elections, monitoring, channellings vote correctly, and being responsible.

Probability in many-worlds theories
Authors: Short Anthony J.
Published: April 2023

We consider how to define a natural probability distribution over worlds within a simple class of deterministic many-worlds theories. This can help us understand the typical properties of worlds within such states, and hence explain the empirical success of quantum theory within a many-worlds framework. We give three reasonable axioms which lead to the Born rule in the case of quantum theory, and also yield natural results in other cases, including a many-worlds variant of classical stochastic dynamics.
Simple master equations for describing driven systems subject to classical non-Markovian noise
Authors: Groszkowski Peter , Seif Alireza , Koch Jens , Clerk A. A.
Published: April 2023

Driven quantum systems subject to non-Markovian noise are typically difficult to model even if the noise is classical. We present a systematic method based on generalized cumulant expansions for deriving a time-local master equation for such systems. This master equation has an intuitive form that directly parallels a standard Lindblad equation, but contains several surprising features: the combination of driving and non-Markovianity results in effective time-dependent dephasing rates that can be negative, and the noise can generate Hamiltonian renormalizations even though it is classical. We analyze in detail the highly relevant case of a Rabi-driven qubit subject to various kinds of non-Markovian noise including 1/f fluctuations, finding an excellent agreement between our master equation and numerically-exact simulations over relevant timescales. The approach outlined here is more accurate than commonly employed phenomenological master equations which ignore the interplay between driving and noise.
