Abstract
Physics-informed neural networks (PINNs) have been used by researchers to solve partial differential equation (PDE)-constrained problems. We evaluate PINNs to solve for frequency-domain acoustic wavefields. PINNs can solely use PDEs to define the loss function for optimization without the need for labels. Partial derivatives of PDEs are calculated by mesh-free automatic differentiations. Thus, PINNs are free of numerical dispersion artifacts. It has been applied to the scattered acoustic wave equation, which relied on boundary conditions (BCs) provided by the background analytical wavefield. For a more direct implementation, we solve the nonscattered acoustic wave equation, avoiding limitations related to relying on the background homogeneous medium for BCs. Experiments support our following insights. Although solving time-domain wave equations using PINNs does not require absorbing boundary conditions (ABCs), ABCs are required to ensure a unique solution for PINNs that solve frequency-domain wave equations, because the single-frequency wavefield is not localized and contains wavefield information over the full domain. However, it is not trivial to include the ABC in the PINN implementation, so we develop an adaptive amplitude-scaled and phase-shifted sine activation function, which performs better than the previous implementations. Because there are only two outputs for the fully connected neural network (FCNN), we validate a linearly shrinking FCNN that can achieve a comparable and even better accuracy with a cheaper computational cost. However, there is a spectral bias problem, that is, PINNs learn low-frequency wavefields far more easily than higher frequencies, and the accuracy of higher frequency wavefields is often poor. Because the shapes of multifrequency wavefields are similar, we initialize the FCNN for higher frequency wavefields by that of the lower frequencies, partly mitigating the spectral bias problem. We further incorporate multiscale positional encoding to alleviate the spectral bias problem. We share our codes, data, and results via a public repository.

The prevalence of overnutrition in Indonesia is increasing from year to year. Overnutrition occurs because of an imbalance between consumed and expended energy. Overnutrition needs a serious attention because it deals with a variety of health problem complications in adult, such as diabetes and heart disease. This research aims to analyze the association between the amount of pocket money and breakfast habit with overnutrition status in elementary school children. Analytical observational research with cross sectional design was conducted in SDN Ploso I-172 Tambaksari Surabaya. The sample size was 52, which was taken by using simple random sampling technique in 4th and 5th grade students. Association among variables were analyzed using Chi-Square test. The result showed that 32.7% of respondents skip breakfast. The mean of respondent’s pocket money was IDR 5.894,23 ± 3.215,06. Majority of respondents were obese (34.6%) and overweight (28.8%). Chi-Square test showed there was an association between the amount of pocket money (p=0.000) and breakfast habits (p=0.005) with overnutrition status. It can be concluded that the amount of pocket money and breakfast skipping habit contribute to overnutrition status in elementary school children. Parents are responsible for providing foods with adequate nutrition for children, habituate children to have breakfast at home, and provide pocket money to children with amount less than IDR 5.894,23 ± 3.215,06.Keywords: breakfast, overnutrition status, pocket money

AWE AT NATURAL BEAUTY AS A RELIGIOUS EXPERIENCE
Authors: Porcher José Eduardo , De Luca-Noronha Daniel 
Published: January 2024

In this paper, we discuss an abductive argument for the existence of God from the experience of awe at natural beauty. If God’s creative work is a viable explanation for why we experience awe at natural beauty, and there is no satisfactory naturalistic explanation for the origins of such experiences, then we have defeasible evidence that God exists. To evaluate the argument’s tenability, we assess the merits of the two main theocentric frameworks that can be marshaled to answer the question of why human beings experience awe at natural beauty: (1) taking the experience of natural beauty as resulting from God’s design intentions and (2) conceiving experiences of natural beauty as religious experiences in themselves. We argue that the presence of phenomenological content the fine-grainedness of which exceeds our descriptive and conceptual capacities is better accounted for by the latter hypothesis: experiencing natural beauty amounts to experiencing divine attributes. We conclude that the argument’s theological premise is tenable and, having previously argued for the empirical premise (Porcher & De Luca-Noronha, 2021), we conclude that awe at natural beauty is best explained by the existence of God.

Published: January 2024

A mística, embora implique certa relação com o suprassensível, apresenta traços fenomenológicos comuns com a experiência sensível do belo e com a criação artística. Este artigo pretende examinar as imprecisas fronteiras entre a mística e a estética a partir de três autores do século XX, estudiosos de Plotino: Evelyn Underhill, Vladimir Jankélévitch e Juan David García Bacca. Primeiramente, será analisado o estatuto da sensibilidade, da beleza e da arte na espiritualidade de Underhill. Em seguida, será verificado de que modo o campo da inefabilidade, ressaltado ao longo da obra de Jankélévitch e, em particular, em sua estética musical, garante a aproximação entre as duas áreas. Em terceiro lugar, será investigada a confluência do caminho místico e do caminho da Beleza na leitura feita por García Bacca do itinerário, prescrito por Plotino, rumo ao Transcendente. A título de conclusão, serão destacados pontos de convergência e de divergência entre os autores.

A PERQUIRIÇÃO DA TRANSCENDÊNCIA NO PENSAMENTO DO JOVEM HEIDEGGER
Authors: Drawin Carlos Roberto 
Published: January 2024

O nosso artigo está dividido em duas partes. A primeira parte visa mostrar como o sentido da transcendência está profundamente enraizado em todo o pensamento heideggeriano. A segunda parte procura ilustrar essa hipótese de leitura recorrendo a alguns textos de juventude do filósofo e os interpretando a partir de diversos estudos sobre a gênese de sua obra. No entanto, pressupomos que a sua relação com o cristianismo não foi ultrapassada nem com a sua ruptura com o “sistema do catolicismo” e nem com o seu afastamento filosófico da teologia. Ao contrário, a experiência cristã, de certa forma, persiste em todo seu itinerário e está presente, mesmo após a “viravolta” (Kehre) dos anos trinta. Essa experiência, para além de qualquer adesão doutrinária, alimenta a questão acerca de Deus como a sempre impensada transcendência encarnada no pensamento da e na existência.

The Dynamic Evolution Model of Chemical and Carbon Isotopic Composition of C<sub>1-3</sub> during the Hydrocarbon Generation Process
Authors: Zhao Heng , Li Yanjie , Liu Wenhui , Zhang Guchun , Wang Yanjun 
Published: January 2024

A new approach is presented for dynamic modeling of chemical and isotopic evolution of C1-3 during the hydrocarbon generation process. Based on systematic data obtained from published papers for pyrolysis of various hydrocarbon sources(type I kerogen/source rock, type II kerogen/source rock, type III kerogen/source rock, crude oil, asphalt, etc), the empirical evolution framework of chemical and isotopic composition of C1-3 during the hydrocarbon generation process was built. Although the empirical framework was built only by fitting large amount of pyrolysis data, the chemical and isotopic composition of C1-3 derived from the pyrolysis experiments all follow the evolution laws, convincing us that it is applicable to the thermal evolution process of various hydrocarbon sources. Based on the simplified formula of the isotopic composition of mixed natural gas at different maturities (δ13Cmixed)
δ13Cmixed=(X〖*n〗_iA 〖*δ〗^13 C_iA+Y〖*n〗_iB 〖*δ〗^13 C_iB)/(X〖*n〗_iA+Y〖*n〗_iB ),
it can be derived that the cumulative isotopic composition of alkane generated in certain maturity interval can be expressed by the integral of the product of instantaneous isotopic composition and instantaneous yield at certain maturity point, and then divided by the cumulative yield of alkane generated in corresponding maturity interval. Thus, the cumulative isotopic composition(A(X)), cumulative yield(B(X)), instantaneous isotope(C(X)),and instantaneous yield(D(x)) in the dynamic model comply with the following formula during the maturity interval of (X0-X)
A(X)=(∫_(X_0)^X▒〖C(X)*D(X)dx〗)/(B(X)),
where A(X) and B(X) can be obtained by fitting of pyrolysis data, and D(x) can also be obtained from the derivation of B(X).
The dynamic model was applied on the pyrolysis data of Pingliang Shale to illustrate the quantitative evolution of cumulative yield ,instantaneous yield, cumulative isotope and instantaneous isotope of C1-3 with increasing maturity.The dynamic model can quantify the yield of methane, ethane and propane as well as δ13C1, δ13C2 and δ13C3 respectively during the hydrocarbon generation process, which is of great significance to evaluate the natural gas resources of hydrocarbon source rock with different maturity and to identify the origin and evolutionary process of hydrocarbons by chemical and isotopic data. Moreover, this model provides an approach to study the dynamic evolution of isotope series of C1-3 (including reversed isotopic series), which is hopeful to reveal the mechanism responsible for isotopic reversal when combined with post-generation studies.
AOA Critical Issues: A Culture of Safety Across All Orthopaedic Professional Endeavors
Authors: Ring David , Adams Julie , Samora Julie , Kamal Robin 
Published: January 2024

Abstract:
Medical professionals strive for a culture of safety in which error is anticipated, systems are designed to catch an error before it causes harm, and each event is an opportunity for specific clinicians and the system they work in to improve. A culture of safety is based on behavioral ethics, which recognizes that the automatic functions of the human mind can lead good people to misstep, and it incorporates tools such as checklists that embody critical thinking in order to help limit missteps and associated harm. Although the discussion surrounding a culture of safety often focuses on patient care, the social contract between physicians and society involves expectations that physicians will use their expertise to promote the public good in all of their professional endeavors. For example, lapses in professional conduct in the management of conflicts of interest and in ethical marketing have led to restrictions in physician self-regulation. Orthopaedic surgeons can cultivate a culture of safety and a growth mindset across all aspects of the profession, including media coverage of musculoskeletal illness, surgeon participation in informational media (e.g., podcasts and blogs), the marketing of oneself or one’s practice, practice patterns and variations, academic discourse, expert legal testimony, the development and implementation of policy and law, and commercial ventures. Systems that anticipate the human potential for missteps; create tools, tactics, and structures to limit missteps and associated harm; and support surgeons and their teams in all professional endeavors can contribute to the effective and fulfilling promotion of the public good.

Background:
Fracture-related infection is one of the most challenging complications in orthopaedic trauma surgery. However, the effect of infection on functional and pain-related outcomes has not been well established. The aims of this study were to evaluate functional recovery for patients with fracture and a deep surgical site infection compared with patients with fracture without infection and to evaluate whether pain severity, social support, and preinjury mental health have a moderating effect on the magnitude and direction of the relationship between deep surgical site infection and functional recovery.

Methods:
This is a secondary retrospective cohort study using prospectively collected data from the VANCO trial (Local Antibiotic Therapy to Reduce Infection After Operative Treatment of Fractures at High Risk of Infection) and the OXYGEN (Supplemental Perioperative Oxygen to Reduce Surgical Site Infection After High Energy Fracture Surgery) trial. In this study, 2,116 patients with tibial plateau, pilon, or calcaneal fractures at high risk for infection were included. Patients were divided into cohorts of patients who experienced a deep surgical site infection and those who did not. The primary outcome measure was the functional outcome using the Veterans RAND 12-Item Health Survey (VR-12).

Results:
After controlling for covariates, deep surgical site infection was independently associated with functional outcome, with a 3.3-point reduction in the VR-12 Physical Component Score, and pain severity was independently associated with functional outcome, with a 2.5-point reduction in the VR-12 Physical Component Score. Furthermore, the Brief Pain Inventory pain severity demonstrated an important moderating effect on the relationship between infection and functional outcome. In patients with lower pain scores, infection had a large negative impact on functional outcome, whereas, in patients with higher pain scores, infection had no significant impact on functional outcome. Furthermore, the functional outcome in the entire cohort remains at only 61% of baseline.

Conclusions:
This study documents the negative impact of postoperative infection on functional recovery after injury, as well as the novel finding of pain severity as an important moderating factor. This study emphasizes not only the importance of developing effective interventions designed to reduce postoperative infection, but also the role that factors that moderate pain severity plays in limiting recovery of physical function.

Published: January 2024

Background:Postoperative nausea and vomiting (PONV) affects patient satisfaction, health care costs, and hospital stay by complicating the postoperative recovery period after adolescent idiopathic scoliosis (AIS) spinal fusion surgery. Our goal was to identify recommendations for optimal management of PONV in AIS patients undergoing posterior spinal fusion (PSF).Methods:We performed a systematic review in June 2022, searching the PubMed and Embase electronic databases using search terms “(Adolescent idiopathic scoliosis) AND (Postoperative) AND (Nausea) AND (Vomiting).” Three authors reviewed the 402 abstracts identified from January 1991 to June 2022. Studies that included adolescents or young adults (<21 years) with AIS undergoing PSF were selected for full-text review by consensus. We identified 34 studies reporting on incidence of PONV. Only 6 studies examined PONV as the primary outcome, whereas remaining were reported PONV as a secondary outcome. Journal of Bone and Joint Surgery Grades of recommendation were assigned to potential interventions or clinical practice influencing incidence of PONV with respect to operative period (preoperative, intraoperative, and postoperative period) on the basis that potential guidelines/interventions for PONV can be targeted at those periods.Results:A total of 11 factors were graded, 5 of which were related to intervention and 6 were clinical practice-related. Eight factors could be classified into the operative period—1 in the intraoperative period and 7 in the postoperative period, whereas the remaining 3 recommendations had overlapping periods. The majority of grades of recommendations given were inconclusive or conflicting. The statement that neuraxial and postoperative systemic-only opioid therapy have a similar incidence of PONV was supported by good (Grade A) evidence. There was fair (Grade B) and poor evidence (Grade C) to avoid opioid antagonists and nonopioid local analgesia using wound catheters as PONV-reducing measures.Conclusion:Although outcomes after spinal fusion for AIS have been studied extensively, the literature on PONV outcomes is scarce and incomplete. PONV is most commonly included as a secondary outcome in studies related to pain management. This study is the first to specifically identify evidence and recommendations for interventions or clinical practice that influence PONV in AIS patients undergoing PSF. Most interventions and clinical practices have conflicting or limited data to support them, whereas others have low-level evidence as to whether the intervention/clinical practice influences the incidence of PONV. We have identified the need for expanded research using PONV as a primary outcome in patients with AIS undergoing spinal fusion surgery.
