Authors: Qiu Jinniao , Yang Yang
Published: November 2023

This paper is devoted to the stochastic optimal control problem of infinite-dimensional differential systems allowing for both path-dependence and measurable randomness. As opposed to the deterministic path-dependent cases studied by Bayraktar and Keller [J. Funct. Anal. 275 (2018) 2096-2161], the value function turns out to be a random field on the path space and it is characterized by a stochastic path-dependent Hamilton-Jacobi (SPHJ) equation. A notion of viscosity solution is proposed and the value function is proved to be the unique viscosity solution to the associated SPHJ equation.

The management of microbiological regime of the irrigated light chestnut soils in the Nizhnee Povolzhye under drip irrigation
Authors: Kalinichenko Roman , Klimakhina Marina
Published: November 2023

There is a certain relation between soil fertility and its microorganism content. The article considers the microbiological characteristics of irrigated light chestnut soils in the Nizhnee Povolzhye on various media. The soil samples were taken in the plow horizon (0-20 cm) in five replications for each experimental variant. To determine and account for the microorganism groups in the studied soil, the following nutrient media were used: MPA (meat-and-peptone agar), Wort – Agar and Czapek’s, Waksman’s. The studies also included the determination of the nutrient content in the soil in order to adjust the fertilizer application system for drip irrigation, since the soil arable layer on the experimental plot was poorly provided with easily hydrolyzed nitrogen and exchangeable potassium, and in medium way with mobile phosphorus. On the irrigated area one selected the plots with onion and cucumber crops with different mineral nutrition and the levels of maintaining pre-irrigation soil moisture, as well as a variant with a virgin (nonirrigated) plot. The development features of microbial communities on irrigated and non-irrigated lands were revealed. In the arable layer of the irrigated light chestnut soil of the Volgograd region, a fungus of the genus Fusarium, bacteria Bacillus subtilis, bacteria of the genus Erwinia were found, which can make it difficult to grow and store agricultural products. The options for maintaining pre-irrigation soil moisture during drip irrigation of vegetable crops did not have any significant effect on the quantitative and qualitative composition of microorganisms. The studied soil, according to agro-chemical analysis, is fertile and can be used for crop growing. Crop cultivation on non-irrigated areas should be carried out with the application of appropriate fertilizers.

Authors: Novianty Inna , Sholihah Walidatush , Puji Mumpuni Restu
Published: November 2023

Hydroponics is a method of growing plants using nutrient solutions. The advantage of hydroponics is that soil can be replaced with a nutrient solution because it can produce its advantages, such as saving land, planting in any area without the need for soil, and producing optimal quality compared to using soil. Technology development is growing rapidly and has created a lot of IoT (Internet of Things) technology. IoT technology can be implemented in hydroponic methods to produce more accurate and well-managed hydroponic plants so that plants are not treated manually. This method comprises six stages: analysis, planning, implementation, testing, and conclusion. Nutrient control in IoT-based hydroponic plants has been widely researched. Many researchers use different work systems and add new features to improve the quality and quantity of hydroponic plant production. Data control is monitored using an application called HyGrow. In obtaining data and information, the author uses observation and qualitative methods by observing and digging up information directly on the hydroponic system in the RH Farm environment. From the test results obtained, this system has successfully controlled and monitored the acidity, temperature conditions, and humidity in hydroponic plants. The percent accuracy of Nutrition and humidity sensors is 98%.

Published: November 2023

Field Work Practice or Internship is a systematic effort carried out by the vocational higher education providers, preparing students to assess the competencies mastered in order to achieve certain attitudes, knowledge, skills, or expertise. There are numerous administrative activities involving four parties simultaneously, which can lead to various problems. Among these issues are students submitting forms that do not comply with the provisions outlined in the Field Work Practice Handbook and students forgetting the stages they have completed during the implementation of the Field Work Practice. Additionally, the supervising lecturers and the Field Work Practice committee face challenges in tracking students’ progress due to mixed-up files. Consequently, the College of Vocational Studies of IPB requires an application that can monitor progress based on access rights and provide assessment forms and score recapitulation directly without manual recapping. The method employed for this study is the prototype method. Online access to the FRIDA App is available through the website https://fridasv.com, allowing users to access the application via a browser on a computer or handheld device connected to the internet.

Imaging Nasal Obstruction: An Objective Evaluation for a Subjective Complaint
Authors: Abreu Vasco R.L.S. , Xavier João A.
Published: November 2023

Nasal obstruction (NO) is a common clinical symptom characterized by a subjective sensation of insufficient airflow through the nasal cavity and may result from various factors, including changes in nasal anatomy, inflammatory conditions, tumoral lesions, and other etiologies. While a thorough medical history and physical examination can often identify its cause, imaging is usually necessary to fully understand the problem. Computed tomography (CT) is the primary imaging modality used to evaluate the nasal cavity and paranasal sinuses, allowing for the identification of potential causes and structural abnormalities. However, when soft tissue characterization is required, magnetic resonance imaging (MRI) is also useful. Understanding the anatomical and pathological basis of NO is crucial for accurate diagnosis and appropriate management. Imaging techniques provide valuable information for identifying the underlying causes of NO and guiding treatment decisions. This article reviews the normal anatomy of the nasal cavity and adjacent paranasal sinuses as well as the several conditions that may affect breathing comfort (tumors, inflammatory diseases, bony and cartilaginous anatomical variants, and “nonobstructive” mucosal thickenings), showing their normal presentation on CT and MRI.
Boron Lewis Acid Catalyzed Hydrophosphorylation of N-Heteroaryl-Substituted Alkenes
Authors: Lee Sarah Yunmi , Kwak Soojin , Choi Jeongin
Published: November 2023

The hydrophosphorylation of N-heteroaryl-substituted alkenes catalyzed by a boron Lewis acid catalyst is reported. This reaction occurs with a range of alkenes bearing N-heterocycles, including pyridines, a quinoline, a pyrrole, and a benzothiazole, resulting in the production of β-N-heteroaryl alkylphosphonates in good yields under additive-free, operationally simple conditions. The mechanistic insights suggest that this hydrophosphorylation involves the deprotonation of the P–H bond of dialkyl phosphites, enabled by the cooperative effects of a boron acid and the basic N-heterocyclic moiety of the alkenes. The resulting phosphonate anion serves as an effective phosphorus nucleophile for the conjugate addition to the concurrently formed N-protonated alkenes. These β-N-heteroaryl alkylphosphonates can be further converted into other valuable organophosphorus compounds through the introduction of an alcohol group or the reduction of the phosphine oxide moiety.
Pyrazolopyridine Ligands in Transition-Metal-Catalyzed C–C and C–Heteroatom Bond-Forming Reactions
Authors: Joo Jung Min , Kang Eunsu
Published: November 2023

Pyrazole-substituted pyridines have emerged as versatile bidentate ligands in transition-metal catalysis, providing opportunities to fine-tune reactivity and selectivity beyond what conventional bipyridine ligands can achieve. This review focuses on two representative pyrazolopyridine ligands: 2-(1H-pyrazol-1-yl)pyridine (1-PzPy) and 2-(1H-pyrazol-3-yl)pyridine (3-PzPy). The 1-PzPy series, characterized by a pyrazole ring serving as a weakly coordinating Lewis basic ligand, offer flexibility in ligand binding. Alternatively, the 3-PzPy series provide both L2- and LX-type binding modes, functioning as hydrogen bond donors and σ-donors, respectively. The structural diversity of pyrazolopyridine ligands enables the development of various synthetic strategies, facilitating cross-coupling, cycloaddition, photocatalytic, and asymmetric reactions. This review highlights the roles of these ligands in advancing transition-metal-catalyzed C–C and C–heteroatom bond-forming reactions.

Abdominal Hypertension after Abdominal Plication in Postbariatric Patients: The Consequence in the Postoperative Recovery
Authors: Morales-Olivera Martin , Hanson-Viana Erik , Rodríguez-Segura Armando , Rendón-Medina Marco A.
Published: December 2023

Background Abdominoplasty with abdominal plication increases intra-abdominal pressure (IAP) and has been previously associated with limited diaphragmatic excursion and respiratory dysfunctions. Many factors found in abdominoplasties and among postbariatric patients predispose them to a higher occurrence. This study aims to evaluate the impact of abdominal plication among postbariatric patients, assess whether the plication increases their IAP, and analyze how these IAP correlate to their postoperative outcome.

Methods This prospective study was performed on all patients who underwent circumferential Fleur-De-Lis abdominoplasty. For this intended study, the IAP was measured by an intravesical minimally invasive approach in three stages: after the initiation of general anesthesia, after a 10-cm abdominal wall plication and skin closure, and 24 hours after the procedure.

Results We included 46 patients, of which 41 were female and 5 were male. Before the bariatric procedure, these patients had an average maximum weight of 121.4 kg and an average maximum body mass index of 45.78 kg/m2; 7 were grade I obese patients, 10 were grade II, and 29 were grade III. Only three patients were operated on with a gastric sleeve and 43 with gastric bypass. We presented six patients with transitory intra-abdominal hypertension in the first 24 hours, all of them from the grade I obesity group, the highest presented was 14.3 mm Hg. We presented 15% (7/46) of complication rates, which were only four seroma and five dehiscence; two patients presented both seroma and wound dehiscence.

Conclusion Performing a 10-cm abdominal wall plication or greater represents a higher risk for intra-abdominal hypertension, slower general recovery, and possibly higher complication rate in patients who presented a lower degree of obesity (grade I) at the moment of the bariatric surgery.

Authors: Torres Alejandra Suyapa Becerra , Alabarse Otávio Prado , Alves Ândria Cléia , Teixeira Ana Luiza , Azevedo Renata Cruz Soares de , Fernandes Arlete
Published: November 2023

Objective To assess the loss to follow-up after emergency care and during 6-months of outpatient follow-up, and the associated variables, among adolescent sexual violence survivors.

Methods This is a retrospective study with review of the medical records of 521 females, aged 10 to 18 years, who received emergency care in a referral service in São Paulo, Brazil. The variables were sociodemographic; personal history; characteristics of abuse, disclosure, and reactions triggered after abuse (physical and mental disorders as well as social changes), psychotropic prescription needs, and moment of abandonment: after emergency care and before completing 6 months of outpatient follow-up. To compare groups of patients lost to follow-up at each time point, we used the Chi-square and Fisher exact tests followed by multiple logistic regression with stepwise criterion for selection of associated variables. We calculated the odds ratio with confidence interval (OR, CI 95%). The level of significance adopted was 5%.

Results A total of 249/521 (47.7%) adolescents discontinued follow-up, 184 (35.3%) after emergency care and 65 (12.4%) before completing outpatient follow-up. The variables of living with a partner (OR = 5.94 [CI 95%; 2.49–14.20]); not having a religion (OR = 2.38 [CI 95%;1.29–4.38)]), having a Catholic religion [OR =  2.11 (CI 95%; 1.17–3.78)]; and not disclosing the abuse [OR = 2.07 (CI 95%; 1.25–3.44)] were associated with loss to follow-up after emergency care. Not needing mental disorder care (OR = 2.72 [CI 95%; 1.36–5.46]) or social support (OR = 2.33 [CI 95%; 1.09–4.99]) were directly associated with loss to outpatient follow-up.

Conclusion Measures to improve adherence to follow-up should be aimed at adolescents who live with a partner and those who do not tell anyone about the violence.

Authors: Israel Jacqueline S. , Loushin Stacy R. , Tetzloff Sabine U. , Ellenbecker Todd , Kaufman Kenton R. , Kakar Sanjeev
Published: December 2023

Background Tennis players often present with ulnar-sided wrist pain, which may reflect repetitive stress and/or faulty mechanics. There is a role for investigating the biomechanics of tennis strokes and how they may relate to wrist pathology. The purpose of this study was to investigate whether three-dimensional motion capture technology and dynamic electromyography (EMG), when used to study groundstrokes in elite junior tennis players, reveals patterns of upper extremity motion that may correlate with the development of clinically relevant pathology.

Case Description Three-dimensional kinematic and EMG data were collected from two United States Tennis Association-ranked adolescent tennis players during groundstrokes. There were several observed differences in the two players' degree and timing of pronation/supination, ulnar/radial deviation, and flexion/extension during their strokes.

Clinical Significance Advanced motion capture technology facilitates a nuanced understanding of complex movements involved in groundstroke production. This methodology may be useful for identifying athletes who are at risk for injury and guiding rehabilitation for players experiencing pain.

Constituting sources is a matter of correlational claims
Authors: Pala Kiran
Published: December 2023

This essay delves into the essentialities of object-giving sources within the formulation of epistemic objectivity. It explores the relationship between objectivity and intentional states, particularly in the context of immediate and transcendent experiences. A key focus of this paradigm is the examination of inferences and how they are held in X’s intentional processes. These claims about inferences contribute to the perception of objectivity by highlighting the epistemological transitions of things that occur in the constitutive ideation. Additionally, the activity within X’s episteme leads to significant articulations that reflect a structural realism of experiences. The essay also introduces a convention of the experiential-intentional process so that the causality manipulations could be avoided by the precents of sources of ideation. In this instance, the central niche is occupied by transcendental reflections of intentionality, which are fundamentally founded on experiences and objectivity, and they possess a distinct rhetorical quality. They manifest as acts, propositional forms, and constituents, all of which contribute to the understanding and justification of objectivity. To establish such a framework that upholds objectivity, certain prerequisites must be met. Firstly, the framework must possess justificational resources that prevent causality manipulations. Secondly, pre-reflective sources should not inter-define causality in epistemic circumstances, although this does not exclude the emergence of causal relations, and thus this approach offers a correlational explanation. Lastly, transcendental reflections should remain compatible with the experiential-intentional process, allowing for the accommodation of subjectivity in the justification of objectivity.
Health literacy, religiosity, and political identification as predictors of vaccination conspiracy beliefs: a test of the deficit and contextual models
Authors: Pavić Željko , Kovačević Emma , Šuljok Adrijana
Published: December 2023

The primary focus of this paper is to investigate the influence of science literacy, particularly health literacy, on vaccine-specific conspiracy beliefs, within the broader context of vaccine hesitancy. The authors tested deficit (scientific literacy shapes science attitudes) and contextual models (contextual variables exert direct influence and influence the connection between literacy and science attitudes) in a survey research study (N = 729) in Croatia. The analytical approach included structural equation modeling with vaccination conspiracy beliefs as the outcome variable and health literacy, religiosity, and political identification as predictors. The results showed that lower health literacy and higher religiosity were related to higher vaccination conspiracy beliefs, which was not the case for political identification. In addition, the moderating effect of religiosity on the relationship between health literacy and conspiracy beliefs was confirmed. In contrast, the moderating effect of political identification was not confirmed, thus partially confirming the stronger version of the contextual model. The authors comparatively discuss the results by evoking specific socio-political characteristics of Croatian society as well as the reactions of political and religious organizations to the COVID-19 pandemic.

Optical neural networks (ONNs) enable high speed, parallel, and energy efficient processing compared to their conventional digital electronic counterparts. However, realizing large scale ONN systems is an open problem. Among various integrated and non-integrated ONNs, free-space diffractive ONNs benefit from a large number of pixels of spatial light modulators to realize millions of neurons. However, a significant fraction of computation time and energy is consumed by the nonlinear activation function that is typically implemented using a camera sensor. Here, we propose a novel surface-normal photodetector (SNPD) with an optical-in–electrical-out (O–E) nonlinear response to replace the camera sensor that enables about three orders of magnitude faster (5.7 µs response time) and more energy efficient (less than 10 nW/pixel) response. Direct efficient vertical optical coupling, polarization insensitivity, inherent nonlinearity with no control electronics, low optical power requirements, and the possibility of implementing large scale arrays make the SNPD a promising O–E nonlinear activation function for diffractive ONNs. To show the applicability of the proposed neural nonlinearity, successful classification simulations of the MNIST and Fashion MNIST datasets using the measured response of SNPD with accuracy comparable to that of an ideal ReLU function are demonstrated.

Published: November 2023

We present an experimental study on ac measurements at low frequencies (below 1 MHz) when the coaxial cables used for the measurement are resistive, as in cryogenic conditions. More precisely, we are interested in admittance or impedance measurements and the accurate determination of the phase. Our experiments were completed using an auto-balancing bridge impedance analyzer and various standard coaxial cables, as well as their serial combinations. We characterize the experimental setup, and then, we analyze and measure the phase shift introduced in impedance measurements by lead resistance. Using basic equations for electrical signal propagation in coaxial cables, we calculate phase shift in the whole frequency range and explain our data in the low frequency limit of our model. We propose a quantitative criterion to determine whether the experimental context is appropriate. If not, we show that by using an original calibration procedure, the imaginary part can be accurately recovered, avoiding artifacts. The calibration procedure can be applied to any ac voltage or current measurement, whatever the detection technique is, with known accuracy.

Authors: Zhang Lingyu , Deng Yuan , Wang Yao
Published: November 2023

Halide perovskites have established their intriguing performances in optoelectronics and been expanded to energy harvesting application when incorporated into polymers due to their polarization related properties. Yet, fundamental understanding of the electrical conduction behavior of such composites has seldomly been addressed. Herein, composite films employing CH3NH3PbBr3 (MAPB) nanoparticles and ferroelectric polymer poly(vinylidenefluoride-co-trifluoroethylene) [P(VDF-TrFE)] have been investigated upon their conduction behaviors. Both electric field and temperature-dependent currents have been thoroughly analyzed based on hopping and space charge-limited current mechanisms in combination with trap energy and trap density calculation from thermal stimulated depolarization currents. The conduction mechanism of MAPB/P(VDF-TrFE) composite has been established within the frame of band diagram. Our studies, thus, are essential for developing high-performance optoelectronics and energy harvesters based on halide perovskites/polymer composites.
On the mechanism of “tulip flame” formation: The effect of ignition sources
Authors: Qian Chengeng , Liberman Mikhail A.
Published: November 2023

The initial stages of hydrogen–air flame propagation in tubes and the mechanism of tulip flame formation are investigated using a high-order numerical code to solve the fully compressible reactive Navier–Stokes equations for a spark or planar igniting flame at the closed end of a tube and propagating to the opposite closed or open end. It is shown that the mechanism of tulip flame formation is universal for both sparked and planar ignited flames in tubes with both ends closed. Flame front inversion results from the tulip-shaped profile of the unburned gas axial velocity near the flame front, which is the result of the superposition of the unburned gas flow generated by the accelerating flame and the reverse flow generated by the rarefaction wave during flame deceleration. In a half-open tube, this mechanism is valid for spark ignited flames. In the case of planar ignition, there is no rarefaction wave, but the growth of bulges on the sidewalls leads to the formation of a tulip flame.

Expansion seal rings are widely used in automobile transmission systems, and their sealing performance plays a vital role in the pressure stability and transmission efficiency of the transmission system. However, investigations into revealing the internal flow mechanism of the expansion seal ring and predicting the power loss of the expansion seal ring are still insufficient. In this study, a two-way fluid–structure interaction model consisting of the shaft, oil sleeve, and expansion seal ring was established. The flow and structural physical fields under a series of operating conditions were simulated, and the effects of oil temperature, rotational speed, and seal pressure differential on leakage rate, deformation, power loss, and contact pressure were analyzed. Further, a power loss prediction model was developed by multiple linear regression method. The results demonstrate that in the internal flow field, the oil flow into and out of the groove is characterized by backward step flow and jet flow, respectively. In the structural field, the maximum deformation and the maximum contact pressure of the main sealing surface appear at the notch of the expansion seal ring, and the seal pressure differential has the most significant influence on it. The relative error between the predicted value of the developed model and experimental values is within 9%, which meets the industrial requirements. This work facilitates scholars to understand the internal flow mechanism and deformation process of expanding seal rings and provides a method to predict sealing ring power loss.
Resonant optical trapping of Janus nanoparticles in plasmonic nanoaperture
Authors: Koya Alemayehu Nana , Li Longnan , Li Wei
Published: November 2023

Controlled trapping of light-absorbing nanoparticles with low-power optical tweezers is crucial for remote manipulation of small objects. This study takes advantage of the synergetic effects of tightly confined local fields of plasmonic nanoaperture, self-induced back-action (SIBA) of nanoparticles, and resonant optical trapping method to demonstrate enhanced manipulation of Janus nanoparticles in metallic nanohole aperture. We theoretically demonstrate that displacement of Au-coated Janus nanoparticles toward plasmonic nanoaperture and proper orientation of the metal coating give rise to enhanced near-field intensity and pronounced optical force. We also explore the effect of resonant optical trapping by employing a dual-laser system, where an on-resonant green laser excites the metal-coated nanoparticle, whereas an off-resonant near-infrared laser plays trapping role. It is found that, at the optimum nanoparticle configuration, the resonant optical trapping technique can result in threefold enhancement of optical force, which is attributed to the excitation of surface plasmon resonance in Janus nanoparticles. The findings of this study might pave the way for low-power optical manipulation of light-absorbing nanoparticles with possible applications in nanorobotics and drug delivery.
Electrical microparticle acceleration by high-speed membrane deformation
Authors: Ichihara D. , Takata R.
Published: December 2023

In this study, we conducted experiments to explore the potential of a low-power exploding foil initiator for accelerating microparticles through high-speed membrane deformation. This involved the use of a conductive layer with a conversion section known as a “bridge,” which was positioned between the substrate and the cover layer. The application of pulsed electrical energy led to Joule heating at the bridge, while the vaporized gas generated impulsive loading, resulting in the deformation of the cover layer. According to the principles of energy conservation, 8.7% of the electrical input energy was converted into kinetic energy for the membrane. This deformation process achieved a velocity of 800 m/s, with a corresponding strain rate of 1.6 × 107 s−1. The applied impulse predominantly induced extension stresses in the cover layer rather than bending stresses. Under these conditions, a 17.5-µm radius polylactic acid bead was propelled and subsequently captured by a silicone gel layer, resembling human dermic skin. Considering factors such as particle clustering and deceleration due to air resistance during supersonic flight, assuming a normal incident angle, it was estimated that approximately half of the ejected particles could reach the human dermic layer, located 200 µm beneath the skin surface. These findings suggest that pulse discharge is a promising method for inducing high-speed membrane deformation, and the electrical microparticle accelerator holds potential for applications in needle-free drug delivery.

Published: November 2023

The uterus is vital for successful reproduction in mammals, and two different types of epithelia (luminal and glandular) are essential for embryo implantation and pregnancy establishment. However, the essential cellular and molecular factors and pathways governing postnatal epithelium maturation, determination, and differentiation in developing uterus are yet to be elucidated. Here, the epithelium of the neonatal mouse uterus was isolated and subjected to single-cell transcriptome (scRNA-seq) analysis. Both the undifferentiated epithelium and determined luminal epithelium were heterogeneous and contained several different cell clusters based on single-cell transcription profiles. Substantial gene expression differences were evident as the epithelium matured and differentiated between postnatal days 1 to 15. Two new glandular epithelium-expressed genes (Gas6andCited4) were identified and validated by in situ hybridization. Trajectory analyses provided a framework for understanding epithelium maturation, lineage bifurcation, and differentiation. A candidate set of transcription factors and gene regulatory networks were identified that potentially direct epithelium lineage specification and morphogenesis. This atlas provides a foundation important to discover intrinsic cellular and molecular mechanisms directing uterine epithelium morphogenesis during a critical window of postnatal development.
