Design And Build An Automatic Plant Sprinkler For A Farmer Group In Klino Village

This volunteer work is being done in Klino Bojonegoro, more specifically in the Bojonegoro and Madiun border region. By supplying IOT-based automatic plant sprinklers for watering the local chrysanthemum horticulture, this PKM activity serves to support farmer organizations in the community. Chrysanthemum and rose picking excursions are one of the tourist attractions in Klino Village, one of the tourist destinations in Bojonegoro. The female farmer organization Blooming Sari is in charge of managing the chrysanthemum cultivation (KTW). Using hoses and padlocks, traditional watering procedures are still used, and they are done in the morning and evening. The approach used in this program is to have casual, one-on-one conversations with farmer groups, followed by observations of field requirements and the creation of tools. The stages of activities completed include site surveys, tool and material analysis, tool creation, tool testing, socialization, monitoring, and PKM program evaluation. This PKM activity resulted to the creation of an IOT-based, smartphone-controllable automatic plant watering solution. There are a number of challenges, including those in tool manufacturing that necessitate numerous trials, pipe installation that requires pipes to match the position point, network limitations, and others. This leads to the conclusion that this PKM activity is effective, capable of resolving issues, and perhaps a solution to the issues facing farmer groups in Klino Bojonegoro village.

work-family enrichment . Untuk meningkatkan work engagement di era pandemi ini, organisasi dapat menerapkan program yang meningkatkan family-supportive supervisor behavior , mengurangi work-family enrichment, dan meningkatkan work-family culture . Kata kunci : work engagement, family-supportive supervisor behavior, work-family enrichment , work-family culture , era pandemi Abstract The pandemic era has modified the work environment, causing employees to spend more time at home, raising the question of whether there has been a shift in work engagement. Work engagement is an important factor in the organization. This study aims to determine how the mechanism of indirect relationships of family-supportive supervisor behavior, work-family enrichment, and work engagement during the pandemic era are moderated by work-family culture. Data was obtained from employees of a government agency located in Jakarta who implemented work from home or a hybrid work system with a minimum of one year of service under the same supervisor. Data collection was done using convenience sampling, with N = 174 (64.9 percent female, average age of 36.5 years). In this study, regression analysis with the Hayes PROCESS model 14 was used as the analytical method. The results of the study support the moderating effect of work-family culture on the indirect relationship of family-supportive supervisor behavior on work engagement through work-family enrichment. In the pandemic era, organization need to increase work engagement by implementing programs that improve family-supportive supervisor behavior, reduce work-family enrichment, and support work-family culture.
Alginate/Gelatin Hydrogel Scaffold Containing nCeO2 as a Potential Osteogenic Nanomaterial for Bone Tissue Engineering

Background Clinicians frequently face difficulties when trying to fix bone abnormalities. Gelatin-Alginate (GA) is frequently employed as a carrier because it is non-toxic, biodegradable, and has a three-dimensional network structure. Meanwhile, cerium oxide nanoparticles (nCeO2) demonstrated high antioxidant enzyme simulation activity. Therefore, in order to develop a porous hydrogel scaffold for the application of bone tissue engineering, an appropriate-type GA-nCeO2 hydrogel scaffold was developed and evaluated. Methods GA-nCeO2 hydrogel scaffold was prepared by the lyophilized method and characterized. The surface morphology and cell adhesion of the scaffold were observed by the scanning electron microscope. CCK8 and live-dead staining methods were used to evaluate its biological safety and cell proliferation. Then the osteogenic differentiation in early and late stages was discussed. The expression of osteogenic genes was also detected by RT-PCR. Finally, a bone defect model was made in SD rats, and bone formation in vivo was detected. Results The results showed that GA-nCeO2 hydrogel scaffold exhibited a typical three-dimensional porous structure with a mean pore ratio of 70.61 ± 1.94%. The GA-nCeO2 hydrogel was successfully endowed with simulated enzyme activity including superoxide dismutase (SOD) and catalase (CAT) after the addition of nCeO2. Osteoblasts demonstrated superior cell proliferation and adhesion on composite scaffolds, and both mineralization test and gene expression demonstrated the strong osteogenic potential of GA-nCeO2 hydrogel. The outcomes of hematoxylin and eosin (H&E) staining and Masson trichrome staining in the femoral defect model of SD rats further supported the scaffold’s favorable biocompatibility and bone-promoting capacity. Conclusion Due to its favorable safety, degradability, and bone formation property, GA-nCeO2 hydrogel was anticipated to be used as a potential bone defect healing material.
Active quenching and gating circuit of the photon counting detector for laser time transfer with improved timing resolution and stability

We are presenting the results of research and development of a new active quenching and gating electronics for Single Photon Avalanche Detector (SPAD). The goal of the work was to develop a new SPAD detector package for Laser Time Transfer ground to space with improved timing resolution and stability. The first version of a SPAD detector is operational on board of GNSS navigation satellites. They are based on 25 μm diameter K14 series SPAD chips. They do provide timing resolution of typically 125 ps and stability of the order of 10 ps. The new control electronics provides timing resolution of 25 ps and timing stability and drifts of the order of one picosecond. The device is constructed on a basis of electronics components for which the space qualified equivalents are commercially available. The device construction, tests and results will be presented in detail.
The Effect of the Independence, Expertise and Activity of the Audit Committee On the Quality of the Financial Reporting Process

This paper critically assesses the importance and impact of 3 main characteristics of audit committee independence, expertise and activity on the overall effectiveness of audit committees and the quality of the financial reporting process, based on corporate governance and regulatory debates and relevant research evidence, combined with statistics and analysis of data relating to these characteristics of audit committees of significant international companies. The results found that audit committee independence plays an important, but questionable, role in the monitoring of financial information, disclosure of internal controls and the company's financial reporting process. Secondly, the expertise of audit committee professionals can enhance the quality of financial reporting. Finally, a diligent audit committee can, to some extent, improve the level of oversight of the financial reporting process of the activity.
K2-ABC: Approximate Bayesian Computation with Infinite Dimensional Summary Statistics via Kernel Embeddings

Complicated generative models often result in a situation where computing the likelihood of observed data is intractable, while simulating from the conditional density given a parameter value is relatively easy. Approximate Bayesian Computation (ABC) is a paradigm that enables simulation-based posterior inference in such cases by measuring the similarity between simulated and observed data in terms of a chosen set of summary statistics. However, there is no general rule to construct sufficient summary statistics for complex models. Insufficient summary statistics will "leak" information, which leads to ABC algorithms yielding samples from an incorrect (partial) posterior. In this paper, we propose a fully nonparametric ABC paradigm which circumvents the need for manually selecting summary statistics. Our approach, K2-ABC, uses maximum mean discrepancy (MMD) as a dissimilarity measure between the distributions over observed and simulated data. MMD is easily estimated as the squared difference between their empirical kernel embeddings. Experiments on a simulated scenario and a real-world biological problem illustrate the effectiveness of the proposed algorithm.
The specific brain activity of dual task coordination: a theoretical conflict-control model based on a qualitative and quantitative review

ABSTRACT Concurrently coordinating two tasks at a time is a prerequisite or an essential competency for some occupations. However, evidence are mixed regarding the specific brain activity of dual task coordination. To this end, the present work systematically reviewed the evidence from the functional neuroimaging studies about dual-task-related brain activations by meta-analysis and narrative syntheses. 59 studies related to the brain activity of dual tasking among the healthy adult population were included in the systematic review, 24 studies among which employed three suitable analysis approaches were further included into the meta-analysis. The meta-analysis employing seed-based effect size mapping method found that the specific dual-task-related brain activations were in the medial part of superior frontal gyrus/middle cingulate cortex, right precuneus, and right inferior gyrus (familywise error (FWE)-corrected p < . 01). The systematic qualitative and quantitative review suggested that dual task coordination might be specifically associated with the conflict-control brain circuit.
Quantification of primary and secondary organic aerosol sources by combined factor analysis of extractive electrospray ionisation and aerosol mass spectrometer measurements (EESI-TOF and AMS)

Abstract. Source apportionment studies have struggled to quantitatively link secondary organic aerosols (SOAs) to their precursor sources due largely to instrument limitations. For example, aerosol mass spectrometer (AMS) provides quantitative measurements of the total SOA fraction but lacks the chemical resolution to resolve most SOA sources. In contrast, instruments based on soft ionisation techniques, such as extractive electrospray ionisation mass spectrometry (EESI, e.g. the EESI time-of-flight mass spectrometer, EESI-TOF), have demonstrated the resolution to identify specific SOA sources but provide only a semi-quantitative apportionment due to uncertainties in the dependence of instrument sensitivity on molecular identity. We address this challenge by presenting a method for positive matrix factorisation (PMF) analysis on a single dataset which includes measurements from both AMS and EESI-TOF instruments, denoted “combined PMF” (cPMF). Because each factor profile includes both AMS and EESI-TOF components, the cPMF analysis maintains the source resolution capability of the EESI-TOF while also providing quantitative factor mass concentrations. Therefore, the bulk EESI-TOF sensitivity to each factor can also be directly determined from the analysis. We present metrics for ensuring that both instruments are well represented in the solution, a method for optionally constraining the profiles of factors that are detectable by one or both instruments, and a protocol for uncertainty analysis. As a proof of concept, the cPMF analysis was applied to summer and winter measurements in Zurich, Switzerland. Factors related to biogenic and wood-burning-derived SOAs are quantified, as well as POA sources such as wood burning, cigarette smoke, cooking, and traffic. The retrieved EESI-TOF factor-dependent sensitivities are consistent with both laboratory measurements of SOA from model precursors and bulk sensitivity parameterisations based on ion chemical formulae. The cPMF analysis shows that, with the standalone EESI-TOF PMF, in which factor-dependent sensitivities are not accounted for, some factors are significantly under- or overestimated. For example, when factor-dependent sensitivities are not considered in the winter dataset, the SOA fraction is underestimated by ∼25 % due to the high EESI-TOF sensitivity to components of primary biomass burning such as levoglucosan. In the summer dataset, where both SOA and total OA are dominated by monoterpene oxidation products, the uncorrected EESI-TOF underestimates the fraction of daytime SOA relative to nighttime SOA (in which organonitrates and less oxygenated CxHyOz molecules are enhanced). Although applied here to an AMS and EESI-TOF pairing, cPMF is suitable for the general case of a multi-instrument dataset, thereby providing a framework for exploiting semi-quantitative, high-resolution instrumentation for quantitative source apportionment.
Prevalence, Causes, and Risk Factors of Presenting Visual Impairment and Presenting Blindness in Adults Presenting to an Examination Center in Suzhou, China

Purpose To evaluate the prevalence, causes, and risk factors of presenting visual impairment (PVI) and presenting blindness among adults in Suzhou, China. Methods A total of 43927 subjects were included in this cross-sectional study. Each subject underwent ophthalmic examinations, including presenting visual acuity (PVA), intraocular pressure (IOP), slit-lamp examination, and fundus examination under the small pupils of each eye. Results Using the World Health Organization (WHO) definition, the prevalence of bilateral PVI, bilateral presenting blindness, monocular PVI, and monocular presenting blindness was 1.59% (95% CI, 1.51–1.67), 0.002% (95% CI, 0.0019–0.0021), 3.87% (95% CI, 3.68–4.06), and 0.19% (95% CI, 0.18–0.20), respectively. Using the United States (US) definition, the prevalence of bilateral PVI, bilateral presenting blindness, monocular PVI, and monocular presenting blindness was 5.83% (95% CI, 5.54–6.12), 0.04% (95% CI, 0.038–0.042), 7.43% (95% CI, 7.06–7.80), and 0.45% (95% CI, 0.43–0.47), respectively. The prevalence of PVI was higher in females (WHO criteria, 2.06%, 95% CI, 1.96–2.16; US criteria, 7.27%, 95% CI, 6.91–7.63) than in males (WHO criteria, 1.2%, 95 CI%, 1.14–1.26; US criteria, 4.65%, 95% CI, 4.42–4.89). The leading cause of PVI is an uncorrected refractive error, followed by cataracts and age-related macular degeneration (AMD). Multivariate analysis proved that the prevalence of visual impairment (PVA, better eye, WHO criteria) increased significantly with older age, higher mean arterial pressure (MAP), higher globulin level, and higher fasting blood glucose (FBG). In addition, it also increased significantly with lower hemoglobin, a lower body mass index (BMI), and a lower arterial stiffness index. In this study, serum creatinine, blood urea nitrogen, uric acid, triglycerides, and the systemic immune-inflammation index (SII) showed no association with visual impairment. Conclusion The leading causes of PVI in Suzhou were uncorrected refractive error and cataracts. The prevalence of PVI increased with females, older age, higher MAP, higher FBG, higher globulin, lower hemoglobin, lower BMI, and lower arterial stiffness index.
A review on Parkinson’s disease symptoms before and after deep brain stimulation treatment

Introduction: Parkinson’s disease (PD), followed by Alzheimer’s disease, is the most common progressive neurodegenerative disease. Tremors, rigidity, akinesia, and disorders are common PD symptoms. Over the last few decades, deep brain stimulation (DBS) of the subthalamic nucleus has become a standard treatment for advanced PD. The aim of this systematic review paper is to see the difference between the symptoms of PD before and after DBS. Methods: We conducted a literature search using PubMed and Google Scholar. We chose research from the past 10 years. We retrieved 64 papers, and seven duplicated papers were removed. We reviewed the abstract for the remaining 57 papers which led to the selection of 29 papers. After applying inclusion and exclusion criteria for the remaining 29 papers, 23 papers in the English language were chosen for our review. Results: Five Randomized Clinical Trials (RCTs) studied the outcomes of DBS and eight RCTs about effects on posture and motor function. Four RCTs investigated the effects on gait and balance, two on tremors, and the remaining two on posture. The effects of DBS on speech and language were compared in two RCTs. Three studies looked at cognitive performance. One RCT studied sleeping versus awake DBS on PD. These studies showed that with DBS treatment, there was significant improvement in posture, motor function, gait, balance, speech, and language. However, more studies are required for the further analysis on dysphagia and urinary dysfunction. Conclusion: Our study contributed to a better understanding of the advantages of DBS for a range of symptoms, but it concluded that additional RCT on dysphagia and urinary dysfunction was required to reach a reliable conclusion. More research is required to determine the effects of DBS on different motor and non-motor PD symptoms to standardize treatment.

A new approach to high-order Boussinesq models

An infinite-order, Boussinesq-type differential equation for wave shoaling over variable bathymetry is derived. Defining three scaling parameters – nonlinearity, the dispersion parameter, and the bottom slope – the system is truncated to a finite order. Using Padé approximants the order in the dispersion parameter is effectively doubled. A derivation is made systematic by separately solving the Laplace equation in the undisturbed fluid domain and then addressing the nonlinear free-surface conditions. We show that the nonlinear interactions are faithfully captured. The shoaling and dispersion components are time independent.
Estimation of Aquifer Parameters Under Transient and Steady State Conditions: 1. Maximum Likelihood Method Incorporating Prior Information

In this series of three papers a method is presented to estimate the parameters of groundwater flow models under steady and nonsteady state conditions. The parameters include values and directions of principal hydraulic conductivities (or transmissivities) in anisotropic media, specific storage (or storativity), interior and boundary recharge or leakage rates, coefficients of head-dependent interior and boundary sources, and boundary heads. In transient situations, the initial head distribution can also be estimated if the system is originally at a steady state. Paper 1 of the series discusses some of the advantage in treating the inverse problem statistically and in regularizing its solution by means of penalty criteria based on prior estimates of the parameters. The inverse problem is posed in the framework of maximum likelihood theory cast in a manner that accounts for prior information about the parameters. Since not all the factors which contribute to the prior errors can be quantified statistically at the outset, the covariance matrices of these errors are expressed in terms of several parameters which, if unknown, can be estimated jointly with the hydraulic parameters by a stagewise optimization process. When transient head data are separated by a fixed time interval, the temporal structure of these data is approximated by a lag-one autoregressive model with a correlation coefficient that can be treated as another unknown parameter. Estimation errors are analyzed by examining the lower bound of their covariance matrix in the eigenspace. Paper 1 concludes by suggesting that certain model identification criteria developed in the time series literature, all of which are based on the maximum likelihood concept, might be useful for selecting the best groundwater model (or the best method of parameterizing a particular model) among a number of given alternatives.
Between-group comparison of principal components — some sampling results

Sampling distributions arc Investigated for the critical angles proposed by Krzanowski (1979) as a means of comparing principal component analyses done on two sets of individuals, each of which has had the same p responses measured on it. A summary of the distributions is presented, by giving mean angles and 95% points. The emphasis is on the null case, when the two sets of individuals are assumed to be independent samples from the same population, but a limited study is also made of the case where the two samples come from different populations.
Epitaxial growth and electric characteristics of cubic SiC on silicon

Single crystals of cubic SiC were heteroepitaxially grown by chemical vapor deposition (CVD) using a SiH4‐C3H8‐H2 system on silicon substrates. To reduce the large lattice mismatch between cubic SiC and silicon, a buffer layer was made by carbonizing the surface of a Si substrate in the CVD system. An optimum condition for the buffer layer formation was determined by x‐ray rocking curve measurements, reflection electron diffraction, and Auger electron spectroscopy. Electrical properties of the epitaxial cubic SiC layer were measured, and the mobilities on the Si(111) substrate were found to be larger than those on the Si(100) substrate. Diode characteristics of epitaxially grown p‐n junctions were also investigated.
