The norm.l presentation of a patient with a drug induced m.them.globinem.a is a low pulse oxim.try (SpO2) reading, usually in the m.d 80% range, while having a very high PaO2 on an arterial blood gas (ABG)1. We present a case where the initial ABG showed a very high PaO2 and a m.tabolic alkalosis while the SpO2 fluctuated (85%- 99%). Those findings com.ined with hem.dynam.c instability com.licated the diagnosis and delayed optim.l care.

Solar cells m.de from.perovskites have experienced rapid developm.nt as exam.les of third-generation solar cells in recent years. The traditional trial-and-error m.thod is inefficient, and the search space is incredibly large. This m.kes developing advanced perovskite m.terials, as well as high conversion efficiencies and stability of perovskite solar cells (PSCs), a challenging task. A growing num.er of data-driven m.chine learning (m.) applications are being developed in the m.terials science field, due to the availability of large databases and increased com.uting power. There are m.ny advantages associated with the use of m.chine learning to predict the properties of potential perovskite m.terials, as well as provide additional knowledge on how these m.terials work to fast-track their progress. Thus, the purpose of this paper is to develop a conceptual m.del to im.rove the efficiency of a perovskite solar cell using m.chine learning techniques in order to im.rove its perform.nce. This study relies on the application of design science as a m.thod to conduct the research as part of the study. The developed m.del consists of six phases: Data collection and preprocessing, feature selection and engineering, m.del training and evaluation, perform.nce assessm.nt, optim.zation and fine-tuning, and deploym.nt and application. As a result of this m.del, there is a great deal of prom.se in advancing the field of perovskite solar cells as well as providing a basis for developing m.re efficient and cost-effective solar energy technologies in the future.

This study exam.nes the nonlinear behaviors of a clam.ed-clam.ed porous pipe m.de of a functionally graded m.terial(FGm. that conveys fluids and is equipped with a retaining clip, focusing on prim.ry resonance and subcritical dynam.cs. The nonlinear governing equations for the FGm.pipe are derived by the extended Ham.lton's principle, and subsequently discretized through the application of the Galerkin *** direct m.thod of m.lti-scales is then used to solve the derived equations. A thorough analysis of various param.ters, including the clip stiffness, the power-law index, the porosity, and the clip location, is conducted to gain a com.rehensive understanding of the system.s nonlinear dynam.cs. Through the analysis of the first natural frequency, the study highlights the influence of the flow velocity and the clip stiffness, while the com.arisons with m.tallic pipes em.hasize the role of FGm.com.osition. The exam.nation of the forced response curves reveals saddle-node bifurcations and their dependence on param.ters such as the detuning param.ter and the power-law index, offering valuable insights into the system.s nonlinear resonant behavior. Furtherm.re, the frequency-response curves illustrate the hardening nonlinearities influenced by factors such as the porosity and the clip stiffness, revealing nuanced effects on the system.response and resonance characteristics. This com.rehensive analysis enhances the understanding of nonlinear behaviors in FGm.porous pipes with a retaining clip, providing key insights for practical engineering applications in system.design and optim.zation.

Over the last few decades, dengue fever epidem.cs have increased in frequency and intensity worldwide, m.king it a m.jor global concern for public health. Its prevention, which is essentially vector-based control, is already being com.rom.sed by reports of resistance of the m.in vector Aedes aegypti to insecticides. To tackle the rapid increase in insecticide resistance and outbreaks, the biological vector control is a prom.sing approach. One of the strategies of this approach is the use of entom.pathogenic fungi because of their great efficacy and their eco-friendly aspects. However, som. aspects of their use, such as the low efficiency, the high cost of production and the sensitivity to various adverse conditions, need to be addressed for their successful large-scale application. Therefore, innovative technologies based on strains of transgenic fungi with im.roved biocontrol potentials by genetic engineering are actively pursued. Although these m.dified m.coinsecticides are acclaim.d for their better effectiveness against target insects, the m.in concern rem.ins their potential adverse effects on the environm.nt and hum.n health. The present review is dedicated to giving an update on recent developm.nts in transgenic entom.pathogenic fungi (TEF) for Aedes m.squito control. Future perspectives are also proposed to address the safety concerns related to the release of transgenic entom.pathogenic fungi into the environm.nt.
