Low Frequency ULF Waves in the Earth's Inner Magnetosphere: Power Spectra During High Speed Streams and Quiet Solar Wind and Seeding of EMIC Waves
Authors: Gamayunov Konstantin V. , Engebretson Mark J.
Published: October 2022

Here, we extend the scope of the Gamayunov and Engebretson (2021, hereinafter Paper 1), https://doi.org/10.1029/2021JA029247 work by analyzing the low frequency ultra‐low‐frequency (ULF) wave power spectra in the Earth's inner magnetosphere during high speed stream (HSS) and quiet solar wind (QSW) driving conditions in the upstream solar wind (SW) and comparing our results to the results of Paper 1, where the statistics of ULF wave power spectra during coronal mass ejections (CMEs) are presented. The most important results of our statistical and comparative analyses are as follows. (a) During CMEs, HSSs, and QSW, the magnetic field power spectra of the transverse and compressional fluctuations are well approximated by power laws in the ∼mHz–Hz frequency range, where on average the parameters of power law fits during CMEs and HSSs are close, and those during QSW differ considerably from the respective parameters during CMEs and HSSs. (b) The dominance of the average compressional power over the average transverse power for the low frequency ULF waves during the 0 < SYM/H ≲ 25 nT geomagnetic conditions may serve as a proxy of HSSs in the upstream SW, whereas the opposite relation between the average powers is an indication of CMEs. (c) Independently of the SW driving conditions, a turbulent energy cascade from low frequencies in the ULF wave frequency range into the higher frequency range exists in the Earth's inner magnetosphere, supplying the nonthermal electromagnetic seed fluctuations needed for the growth of electromagnetic ion cyclotron waves (∼Hz) due to relaxation of unstable distributions of energetic magnetospheric ions.
Pier‐Based Measurements of Air‐Sea Momentum Fluxes Over Shoaling Waves During DUNEX
Authors: Potter Henry , Collins Clarence O. , Ortiz‐Suslow David G.
Published: October 2022

Open‐ocean homogeneity is violated in the near shore region by wave shoaling and breaking, varying wind‐swell incidence angles, complex currents patterns, rapid bathymetric changes, and shore‐side topographic features. Consequently, existing drag coefficient parameterizations, which were largely developed in deep water, are not effective. This has an adverse impact on marine forecasts, weather and climate models, and coastal morphology prediction. There exists a critical need to identify and systematically quantify the impact of coastal processes and features on the momentum flux over a wide range of wind speeds. As part of the DUring Nearshore Event eXperiment at the Field Research Facility in Duck, NC, six months of direct flux observations were collected from a tower at the end of a 560 m pier. These were used to study the variability of the aerodynamic drag coefficient. Results show that for winds above 3 m s−1 the drag coefficient was between 15% and 50% higher for onshore winds when compared to alongshore. This is attributed to more energy in the downwind component of the flux around the dominant wave frequency for onshore winds, and is independent of wind speed. Holistically, the Coupled Ocean Atmosphere Response Experiment (COARE) algorithm over predicts the drag coefficient for shoaling waves. When separated by wind direction, COARE best predicts the drag coefficient for onshore winds. The results of this study can help the development of more robust nearshore momentum flux parameterizations. This will ultimately lead to improved weather and climate forecasting in the littoral zone, and more physically realistic short‐ and long‐term coastal resilience strategies.

Rivers and estuaries are important conduits and reactors for organic matter (OM). Despite the substantial export of terrestrial OM by rivers, only a small proportion of this material reaches the open ocean. One potentially important mechanism contributing to the removal of terrestrial dissolved OM (DOM) is flocculation; a process that transforms DOM into larger size fractions that can settle into sediment pools. Here we investigate the role of flocculation in adjacent boreal coastal systems over three consecutive seasons. Flocculation experiments, which include the artificial salting of freshwater DOM to mid (12 psu) and high salinity (25 psu), and a 1:1 mixture of freshwater DOM with their respective saline endmember, highlight a potentially important source of particulate carbon (PC) in boreal estuaries. Along with a 3.5% ± 1.0% removal of dissolved organic carbon (DOC) and 44% ± 16% dissolved iron (DFe), the potential for flocculation of these constituents significantly increased with increasing salinity from 12 to 25 psu. The particulate matter (PM) produced by salt‐induced flocculation was comparable to in situ PC concentrations (in situ PC = 27.5 μmol L−1 and flocculated PC = 15.0 μmol L−1) and stable carbon isotopic signatures (in situ PM = −28.8‰ and flocculated PM = −28.3‰). DFe:DOC and Sr were the only parameters that could significantly explain the degree of carbon and iron flocculation. This demonstrates the importance of DOC, DFe, and optical properties, and the predictive value of DFe:DOC for understanding DOM susceptibility to flocculation and its relevance and contribution to regional and global carbon budgets.

Acute myeloid leukemia (AML) is a rapidly progressing and often fatal hematopoietic malignancy. Venetoclax (VEN), a recent FDA-approved BCL-2 selective inhibitor, has high initial response rates in elderly AML patients, but the majority of patients eventually acquire resistance. Multiple studies have demonstrated that the female sex is associated with better outcomes in patients with AML, which are predominantly attributed to estrogen signaling. As a novel membrane estrogen receptor, G protein-coupled estrogen receptor (GPER)-mediated-rapid estrogen effects have attracted considerable attention. However, whether targeting GPER enhances the antileukemic activity of VEN is unknown. In this study, we first demonstrated that GPER expression was dramatically reduced in AML cells owing to promoter hypermethylation. Furthermore, pharmacological activation of GPER by G-1 combined with VEN resulted in synergistic antileukemic activity in vitro and in vivo. Mechanistically, G-1/VEN combination synergistically triggered concurrent mitochondria-related apoptosis and gasdermin E (GSDME)-dependent pyroptosis by activating p38-MAPK/myeloid cell leukemia 1 (MCL-1) axis. Importantly, leukemic pyroptosis heightened CD8+ T cell immune function by releasing interleukin (IL)-1β/18 into the tumor microenvironment. Our study corroborates that GPER activation shows a synergistic antileukemic effect with VEN, making it a promising therapeutic regimen for AML.

Despite the importance of high-latitude surface energy budgets (SEBs) for land-climate interactions in the rapidly changing Arctic, uncertainties in their prediction persist. Here, we harmonize SEB observations across a network of vegetated and glaciated sites at circumpolar scale (1994–2021). Our variance-partitioning analysis identifies vegetation type as an important predictor for SEB-components during Arctic summer (June-August), compared to other SEB-drivers including climate, latitude and permafrost characteristics. Differences among vegetation types can be of similar magnitude as between vegetation and glacier surfaces and are especially high for summer sensible and latent heat fluxes. The timing of SEB-flux summer-regimes (when daily mean values exceed 0 Wm−2) relative to snow-free and -onset dates varies substantially depending on vegetation type, implying vegetation controls on snow-cover and SEB-flux seasonality. Our results indicate complex shifts in surface energy fluxes with land-cover transitions and a lengthening summer season, and highlight the potential for improving future Earth system models via a refined representation of Arctic vegetation types.

Published: October 2022

Chirality is a manifestation of the asymmetry inherent in nature. It has been defined as the symmetry breaking of the parity of static objects, and the definition was extended to dynamic motion such that true and false chiralities were distinguished. Recently, rotating, yet not propagating, atomic motions were predicted and observed in two-dimensional materials, and they were referred to as ‘chiral phonons’. A natural development would be the discovery of truly chiral phonons that propagate while rotating in three-dimensional materials. Here we used circularly polarized Raman scattering and first-principles calculations to identify truly chiral phonons in chiral bulk crystals. This approach enabled us to determine the chirality of a crystal in a non-contact and non-destructive manner. In addition, we demonstrated that the law of the conservation of pseudo-angular momentum holds between circularly polarized photons and chiral phonons. These findings are expected to help develop ways for transferring the pseudo-angular momentum from photons to electron spins via propagating chiral phonons in opto-phononic-spintronic devices.

Several studies have shown that the pre-vaccination immune state is associated with the antibody response to vaccination. However, the generalizability and mechanisms that underlie this association remain poorly defined. Here, we sought to identify a common pre-vaccination signature and mechanisms that could predict the immune response across 13 different vaccines. Analysis of blood transcriptional profiles across studies revealed three distinct pre-vaccination endotypes, characterized by the differential expression of genes associated with a pro-inflammatory response, cell proliferation, and metabolism alterations. Importantly, individuals whose pre-vaccination endotype was enriched in pro-inflammatory response genes known to be downstream of nuclear factor-kappa B showed significantly higher serum antibody responses 1 month after vaccination. This pro-inflammatory pre-vaccination endotype showed gene expression characteristic of the innate activation state triggered by Toll-like receptor ligands or adjuvants. These results demonstrate that wide variations in the transcriptional state of the immune system in humans can be a key determinant of responsiveness to vaccination.
An acoustic signature of extreme failure on model granular materials
Authors: Nguyên T. T. T. , Doanh T. , Bot A. Le , Dalmas D.
Published: October 2022

Unexpectedly, granular materials can fail, the structure even destroyed, spontaneously in simple isotropic compression with stick-slip-like frictional behaviour. This extreme behaviour is conceptually impossible for saturated two-phase assembly in classical granular physics. Furthermore, the triggering mechanisms of these laboratory events remain mysterious, as in natural earthquakes. Here, we report a new interpretation of these failures in under-explored isotropic compression using the time-frequency analysis of Cauchy continuous wavelet transform of acoustic emissions and multiphysics numerical simulations. Wavelet transformation techniques can give insights into the temporal evolution of the state of granular materials en route to failure and offer a plausible explanation of the distinctive hearing sound of the stick-slip phenomenon. We also extend the traditional statistical seismic Gutenberg–Richter power-law behaviour for hypothetical biggest earthquakes based on the mechanisms of stick-slip frictional instability, using very large artificial isotropic labquakes and the ultimate unpredictable liquefaction failure.

Published: October 2022

Antiretroviral Treatment (ART) has significantly decreased HIV-related morbidity and mortality among children despite the issue of drug resistance and subsequent treatment failure appearing as a challenge. Different studies have been conducted in Ethiopia regarding the prevalence of first-line ART failure among children but the magnitudes of these studies were inconsistent and had great variability. This review aimed to estimate the pooled prevalence of first line ART failure among children and its association with drug substitution and sex of children among first-line ART users in Ethiopia. The review was conducted using both published and unpublished studies until September 2020 in Ethiopia. MEDLINE, PubMed, Hinari, Web of Science, Google Scholar, Africa journal online (AJOL), Open gray literature, and online repository articles were searched. The quality of individual studies was assessed by Joanna Briggs Institute's (JBI) critical appraisal checklist. The statistical analysis was done by STATA-14 software and a random effect model was used. Heterogeneity was assessed using forest plot Cochrane Q–test and I-squared statistic. Publication bias was checked by using a funnel plot and Egger’s and Begg’s statistical tests. The interpretation was made by an odds ratio and with their respective 95% confidence intervals. The heterogeneity rate was 90% and Begg’s and Egger’s for publication bias were insignificant with p-values of 0.89 and 0.11 respectively. The pooled prevalence of pediatric first line ART failure in Ethiopia was 14.98% (95% CI 11.74, 18.21). Subgroup analysis showed that the highest failure rate was virological (9.13%). Female children had 1.4 times more risk of first-line ART failure (OR = 1.42; 95% CI 1.08, 1.85). First-line ART failure among children in Ethiopia is considerably high. Being female increases the likelihood of facing first line ART failure. More attention should be given to female children.

This study aims to investigate novel applications for chicken feather waste hydrolysate through a green, sustainable process. Accordingly, an enzymatically degraded chicken feather (EDCFs) product was used as a dual carbon and nitrogen source in the production medium of bacterial cellulose (BC). The yield maximization was attained through applying experimental designs where the optimal level of each significant variable was recorded and the yield rose 2 times. The produced BC was successfully characterized by FT-IR, XRD and SEM. On the other hand, sludge from EDCFs was used as a paper coating agent. The mechanical features of the coated papers were evaluated by bulk densities, maximum load, breaking length, tensile index, Young’s modulus, work to break and coating layer. The results showed a decrease in tensile index and an increase in elongation at break. These indicate more flexibility of the coated paper. The coated paper exhibits higher resistance to water vapor permeability and remarkable oil resistance compared to the uncoated one. Furthermore, the effectiveness of sludge residue in removing heavy metals was evaluated, and the sorption capacities were ordered as Cu ++  > Fe ++  > Cr ++  > Co ++ with high affinity (3.29 mg/g) toward Cu ++ and low (0.42 mg/g) towards Co ++ in the tested metal solution.

Published: October 2022

The aim of the study was to compare the shape of the feet, the mobility of the metatarsophalangeal and interphalangeal joints and the flexibility of the calf muscles in older women with hallux valgus versus middle-aged women with and without this deformation to identify the presence of features which correlate particularly strongly with hallux valgus, and on which prophylaxis and conservative treatment should focus. The study involved 201 women: 92 aged 60–84 years with hallux valgus of both toes, 78 aged 38–59 with hallux valgus of both toes, and 31 aged 38–57 years with correctly shaped feet. The intensity of pain in the foot, the valgus angle of the big toe and fifth toe, the longitudinal and transverse arches of the foot, the symmetry of foot load with body weight, toe joint mobility and muscle flexibility were analysed. Both groups of women with hallux valgus differed from women with normal feet in the height of the transverse arch, the extent of dorsal extension in the first metatarsophalangeal joint and plantar flexion in the first interphalangeal joint. Older women were additionally characterised by reduced plantar flexion in the metatarsophalangeal joint of the big toe, limited flexibility of the soleus and gastrocnemius muscles as well as less pain in the toe area than in the foot itself. The most characteristic changes which were observed in older women with hallux valgus are a limited range of motion in the MTP and IP joints of the big toe, a reduced transverse arch and increased restriction of calf muscle flexibility.

Published: October 2022

Osteoporosis (OP) is characterized by diminished bone mass and deteriorating bone structure that increases the chance of fractures in the spine, hips, and wrists. In this paper, a novel data processing method of artificial intelligence (AI) is used for evaluating, predicting, and classifying OP risk factors in clinical data of men and women separately. Additionally, artificial intelligence was used to suggest the most appropriate sports programs for treatment. Data was obtained from dual-energy x-ray absorption scanning center of Ayatollah Kashani, Milad, and Khatam al-Anbia hospitals in Tehran, Iran. The subjects included 1224 men and women. Models were developed using decision tree, random forest (RF), k-nearest neighbor, support vector machine, gradient boosting (GB), Extra trees, Ada Boost (AB), and artificial neural network multilayer perceptron analysis to predict osteoporosis and to recommend sports programs. Data was divided into training (80%) and test dataset (20%). The results were obtained on a 20% test dataset. Area under receiver operating characteristic curve (AUROC) was used to compare the performance of the models. To predict healthy individuals, osteopenia and osteoporosis, the FR algorithm with AUROC 0.91 performed best in men and the GB algorithm with AUROC 0.95 performed best in women compared to other classification algorithms. Prediction of RF algorithm in women and men with AUROC 0.96 and 0.99, respectively, showed the highest performance in diagnosing the type of exercise for healthy individuals and those with osteopenia and OP. Eight AI algorithms were developed and compared to accurately predict osteoporosis risk factors and classify individuals into three categories: healthy, osteopenia, and OP. In addition, the AI algorithms were developed to recommend the most appropriate sports programs as part of treatment. Applying the AI algorithms in a clinical setting could help primary care providers classify patients with osteoporosis and improve treatment by recommending appropriate exercise programs.

Twitter Usage About Stuttering
Authors: Azios Michael , Rangarathnam Balaji , Jianyuan Ni , Irani Farzan , Bellon-Harn Monica , Manchaiah Vinaya
Published: October 2022

Purpose:

The objective of this study was to examine specific patterns of Twitter usage using common reference to stuttering.

Method:

The study used cross-sectional analysis of data generated from Twitter data. Twitter content, language, reach, users, accounts, temporal trends, and social networks were examined.

Results:

We identified and analyzed around 270,000 tweets from May to September 2018. Of the 100 most active Twitter accounts, individuals owned 64% compared with 31% owned by organizations. The individual accounts mainly consisted of comedians who stutter and individual's accounts. Of the individual accounts, 61% belonged to people who did not stutter or significant others of persons who stutter (PWSs). PWSs or significant others of PWSs accounted for 10.9% and 28.1%, respectively. Three unique tweets were identified as each having a reach of over 8 million Twitter users, with the greatest reach exceeding 40 million users. Temporal analysis identified marked retweet outliers (> 2,800 and > 2,200 retweets per day) that corresponded with a prank call made to the president on air force one by Stuttering John. Results indicate that, during data collection, Twitter is a platform that primarily functions to assail political opponents or denigrate adversaries, which further enhances the negative stereotypes about stuttering.

Conclusions:

The conclusions are based on the 100 most active/highest reach Twitter accounts. Twitter accounts owned by individuals outnumbered organization accounts, and people who do not stutter were the most frequently active account type. This study offers important insights regarding existing trends and offers an informed direction for future advocacy for PWSs and their supporting community via Twitter.
Improvement the Capacity of Electrical Energy in Residential Using PV With On-Grid System
Authors: Kusmantoro Adhi , Farikhah Irna
Published: October 2022

As one of the renewable energy sources, sunlight or solar energy is considered appropriate to be one of the alternative sources of electrical energy that can be used. In this study, an on-grid system simulation model was carried out using PV. The goal is to find out the characteristics of the energy obtained using the control logic algorithm. In this simulation model design, previously calculations were carried out to determine pv capacity, because it will be adjusted to the power capacity used in residential houses. In this discussion, it is in accordance with the electricity needs of residential houses of 1,500 Watts or hourly energy conumsion of 1.5 KWh. This electrical load will be on at 07.00 to 17.00, meaning that this electric load will consume electric power for 10 hours. Then the total energy consumed per day is 1.5 KWh. In this simulation, 2 100 Wp (Watt peak) solar panels with an output voltage of 12 V DC are used. In a day, it can more or less produce electricity of 200 Wp x 10 hours of heating = 2,000 Wh.

The electricity supply reliability is very important to improve electricity supply quality to consumers. Customers in Simpang Lima area, which located in the heart of the city, expect PLN to improve electricity supply reliability around Simpang Lima area, considering that Simpang Lima is known as culinary and business center in Semarang. However, sometimes blackouts occur during busy time which cause losses. Therefore, this study was conducted on the factors that cause blackouts and the solutions used to overcome these problems. Also, this study is conducted to improve electricity supply reliability in the Simpang Lima area and to reduce ENS. Currently, Simpang Lima area is still using the spindle system with medium voltage grid. Consequently, this system will be changed to a Closed Loop system. On the other hand, there are many buildings that use huge electricity load. For instance, Departemen Industri dan Perdangangan, Bank Indonesia, Telkomsel Semarang, DPRD, and Polda Jawa Tengah buildings. These buildings possess loads between 300-400 Amperes. Thus, the electrical supply is only generated from Simpang Lima substation. There will be further problem if blackout occurs in this substation. To avoid unexpected blackouts, this area will be set with the Zero Down Time concept. Zero Down Time is the concept of a power grid that will never goes out. Later, the Simpang Lima area that still uses the Spindle medium voltage grid will be changed to a Closed Loop with medium voltage grid system. Furthermore, this area will be supplied from Simpang Lima substation and the Kalisari substation.

Authors: Intan Wardyani Anastasia , Candria Mytha
Published: October 2022

The Railway Children is a classic children book that has captured the attention of millions of readers of all ages. The book presents the story of three siblings, Roberta, Peter and Phyllis, whose wealthy and happy life is overturned after their father is imprisoned due to a false accusation of spying. They continue to keep up their spirits and do good for others, and it is through these children protagonists’ adventures and heroic acts. The children’s courages acts are the reasons we are interested in investigating the novel more deeply. Nevertheless, we are particularly interested in figuring out their heroism as communicated through their use of commissives. Commissive speech acts are produced when the children express their commitments to do something in the future. Their commissive acts would be studied with reference to Searle’s (1980) categorization of commissives so that we can discover the types of commissives Roberta, Peter and Phyllis utter, and we can deduce which of those acts of commissives that communicate hero functions. The theoretical framework of heroism and hero functions that we use in this study is that of Kinsella, Ritchie, and Igou (2015), whom we consider to be providing a clear model of hero functions.

The issue of the environment is still an existing topic until now. People from all around the world are still voicing their concern about conservation efforts to fight against pollution and resource depletion. These efforts are also often raised in literary works. One of the literary works considered to focus on the environment and the theme of ecology is the anime Ponyo on the Cliff by the Sea, directed by Hayao Miyazaki. Thus, this study focuses on the representation of changes in environmental virtue ethics applied in mentioned anime. This study applies the theory of deep ecology and shallow ecology proposed by Arne Naess and uses qualitative analysis methods and literary studies. According to the analysis, human indifference to nature manifests in the form of marine environment pollution in the form of garbage and household waste dumped into the ocean, which is the value of shallow ecology ethics. In addition, there are also forms of human concern for coexistence with nature and the emphasis on the rights of other creatures to live, which are the values of deep ecology ethics. Thus, we can see that the environmental virtue ethics have shifted from shallow ecology to deep ecology.
