Experimental investigation of the low‐frequency capacitive response of a plasma sheath

Several theoretical models are examined for the low‐frequency capacitive response of the ion sheath surrounding both planar and cylindrical Langmuir probes in a collisionless plasma. It is found that a recent theoretical approach by Shkarofsky, based on the total probe surface charge derived from Gauss's law, predicts values for both the low‐frequency, capacitance and the transient charge flow which are as much as an order of magnitude smaller than that predicted based on the electron current flow caused by the motion of the sheath edge, e.g., Kamke and Rose. This discrepancy is attributed to the neglect by Shkarofsky of the transient ion conduction current through the sheath. Additionally, a recent theory by Rosa for the complex impedance of a planar sheath is seen, in the limit of low frequency, to be in agreement with that predicted following Kamke and Rose. Experimental measurements have been made, for both pulsed and rf‐driven probes, of the transient charge flow to the probe and the effective low‐fr.
Performance Analysis of Oil Palm Companies Based on Barcode System through Fit Viability Approach: Long Work as A Moderator Variable

Novelty technology will be capable of increasing the performance company's coconut palm oil, one of them being the barcode system. So from that, I needed something to study to know how to influence suitability, continuity and use of the barcode system against the performance company coconut palm. Study this using a long working variable as a moderator variable. The study aims to analyze the effect of fit, viability, and use on the performance of a business company's coconut palm based on the Barcode System. Study this using 237 samples of employee data collected through stratified proportional random sampling at PT LNK from April 2022 to June 2022. Data were analyzed by SEM-PLS analysis with SMARTPLS software 3. An overview of the Barcode System via the Fit-Viability approach has been presented in the paper. Research results show that the performance of the business is affected by viability and use, but not affected by compatibility. Working time takes effect compatibility and compatibility to the assignment will be the taller when working long hours. Paper contributes to the development barcode system at PT LNK. Expected barcode system used by all companies coconut palm oil and can be integrated into the cloud-based data so that it could generate production data in real-time.
A Data-Driven Comparative Analysis of Lithium-Ion Battery State of Health and Capacity Estimation

Abstract Researchers are focused toward the development of electric vehicles and hybrid electric vehicles for the preservation of the ecosystem. Energy storage, conversely, became essential with these changes in vehicular technology. This opens new research fronts and introduces complex problems that are to be investigated regarding the primary storage element. Battery modeling offers improved efficiency, safety, and reliability. Lithium-ion batteries are a popular source of energy in many applications, especially for electric vehicles because of their high performance and high energy density. However, there exist some inherent issues like complex electrochemical reactions that make accurate monitoring a challenging task. This article performs a comparative study of the existing battery state of health (SOH) monitoring and capacity estimation techniques using the NASA dataset for lithium-ion batteries. Charging cycle datasets for voltage, current, and temperature are used for feature identification and extraction. After the modeling of extracted features, the SOH and the capacity of four batteries are estimated using three data-driven techniques. Including convolutional neural network, feed-forward neural network, and long short-term memory (LSTM), and their results are compared. The comparative analysis highlights an outstanding performance and high accuracy of the LSTM-based machine learning technique because of the inherited long-term memory of the LSTM. The study, therefore, recommends the use of LSTM to researchers for battery health monitoring and capacity estimation with the highest possible accuracy.
Heart Rate Variability Impairment Is Associated with Right Ventricular Overload and Early Mortality Risk in Patients with Acute Pulmonary Embolism

The association between heart rate variability (HRV) and mortality risk of acute pulmonary embolism (APE), as well as its association with right ventricular (RV) overload is not well established. We performed an observational study on consecutive patients with confirmed APE. In the first 48 h after admission, 24 h Holter monitoring with assessment of time-domain HRV, echocardiography and NT-proBNP (N-terminal pro-B-type natriuretic peptide) measurement were performed in all participants. We pre-examined 166 patients: 32 (20%) with low risk of early mortality, 65 (40%) with intermediate–low, 65 (40%) with intermediate–high, and 4 (0.02%) in the high risk category. The last group was excluded from further analysis due to sample size, and finally, 162 patients aged 56.3 ± 18.5 years were examined. We observed significant correlations between HRV parameters and echocardiographic signs of RV overload. SDNN (standard deviation of intervals of all normal beats) correlated with echocardiography-derived RVSP (right ventricular systolic pressure; r = −0.31, p = 0.001), TAPSE (tricuspid annulus plane systolic excursion; r = 0.21, p = 0.033), IVC (inferior vena cava diameter; r = −0.27, p = 0.002) and also with NT-proBNP concentration (r = −0.30, p = 0.004). HRV indices were also associated with APE risk stratification, especially in the low-risk category (r = 0.30, p = 0.004 for SDNN). Univariate and multivariate analyses confirmed that SDNN values were associated with signs of RV overload. In conclusion, we observed a significant association between time-domain HRV parameters and echocardiographic and biochemical signs of RV overload. Impaired HRV parameters were also associated with worse a clinical risk status of APE.
Nearly incompressible fluids. II - Magnetohydrodynamics, turbulence, and waves

The theory of nearly incompressible (NI) fluid dynamics developed previously for hydrodynamics is extended to magnetohydrodynamics (MHD). On the basis of a singular expansion technique, modified systems of fluid equations are derived for which the effects of compressibility are admitted only weakly in terms of the different possible incompressible solutions (thus ‘‘nearly incompressible MHD’’). NI MHD represents the interface between the compressible and incompressible magnetofluid descriptions in the subsonic regime. The theory developed here does not hold in the presence of very large thermal, gravitational, or field gradients. It is found that there exist three distinct NI descriptions corresponding to each of the three possible plasma beta (β ≡ the ratio of thermal to magnetic pressure) regimes (β≪1, β∼1, β≫1). In the β≫1 regime, the compressible MHD description converges in the low Mach number limit to the equations of classical incompressible three‐dimensional (3‐D) MHD. However, for the remaining p.
A first passage time distribution for a discrete version of the Ornstein–Uhlenbeck process

The probability of the first entrance to the negative semi-axis for a one-dimensional discrete Ornstein–Uhlenbeck (O-U) process is studied in this work. The discrete O-U process is a simple generalization of the random walk and many of its statistics may be calculated using essentially the same formalism. In particular, the case in which Sparre-Andersen's theorem applies for normal random walks is considered, and it is shown that the universal features of the first passage probability do not extend to the discrete O-U process. Finally, an explicit expression for the generating function of the probability of first entrance to the negative real axis at step n is calculated and analysed for a particular choice of the step distribution.
Colonization Rate and Associated Factors of Non-Pathogenic Neisseria Species, and Moraxella catarrhalis Among Healthy School Children in Gondar, Northwest Ethiopia

Background Although commensal Neisseria species inhabiting mucosal surfaces in the upper respiratory tract (URT) are rarely associated with infections, their presence in the area has been linked to the development of immunity against N. meningitidis and the source of antibiotic resistance determinants in pathogenic species. M. catarrhalis in the oropharynx of children is also a predisposing factor for otitis media. As a result, determining the oropharyngeal carriage rate of these commensal species and associated factors among healthy schoolchildren is substantial. Materials and Methods This community-based cross-sectional study was conducted in Gondar, Northwest Ethiopia, from January to April 2019. A multi-stage and simple random sampling technique were used to select schools and participants, respectively. A total of 524 oropharyngeal swabs were collected using cotton swabs. Modified Thayer-Martin media was used for primary bacterial isolation, and battery of biochemical tests was performed to identify species. For frequencies, descriptive statistics were computed and the logistic regression model was used to see the relationship between dependent and independent variables. Results A total of 524 healthy schoolchildren with a mean age of 12.2 ± 2.74 years participated in this study. The overall oropharyngeal carriage rate was 21.8% (114/524). Of these, N. meningitidis, N. lactamica, N. sicca, and M. catarrhalis were identified in 53 (46.5%), 14 (12.3%), 11 (9.6%), and 36 (31.6%) children, respectively. The culture positivity rate was higher at a younger age, which was 8.1%, 11.3%, and 14.9% in ages between 15–18, 11–14, and 7–10, respectively. The oropharyngeal carriage was significantly associated with the number of students per class (>40). Conclusion There is a higher proportion of carriers of commensal N. lactamica and M. catarrhalis in Gondar town schoolchildren. The oropharyngeal carriage rate was associated with a crowded classroom. The characterization of non-pathogenic Neisseria species and M. catarrhalis in the study area can support the diagnosis of patients suspected of having N. meningitis infections.
Combined Thermosensitive Gel Co-Loaded with Dermaseptin-PP and PTX Liposomes for Effective Local Chemotherapy

Introduction Chemotherapeutic drugs are often ineffective due to the delivery. Local chemotherapy, which has high drug concentration, low systemic toxicity, and long duration, has shown excellent potential. Cationic antimicrobial peptides have been proved to enhance the tumor cells’ uptake of chemotherapeutic drugs through the membrane-breaking effect. In this study, we designed and developed a thermosensitive gel co-loaded with Dermaseptin-PP and paclitaxel liposomes to increase local chemotherapy. Methods The paclitaxel liposomes were prepared. Then, it was co-loaded with Dermaseptin-PP in a poloxamer-based thermosensitive gel to obtain Dermaseptin-PP/paclitaxel liposomes gel. The thermosensitivity of gels was investigated by test tube inversion method. The rheology was tested by rheometer. The in vitro cytotoxicity and the permeation in tumor of gels were examined by H157 cells and the 3D cell model, respectively. The retention in tumor and antitumor activity of gels were evaluated by H157 tumor-bearing nude mice. Results The particle size of paclitaxel liposomes was 148.97 ± 0.21 nm. The encapsulation rate was 86.1%, and the drug loading capacity was 19.4%. The gels had slow-release and temperature-sensitive properties. The porous 3D network structure of the gels could ensure that the drug was fixed into the tumor. In vitro and in vivo distribution studies showed that Dermaseptin-PP promoted the permeation of the gels in H157 multicellular tumor spheres and achieved longer retention in tumor. In vitro and in vivo antitumor studies demonstrated that Dermaseptin-PP/paclitaxel liposomes gel significantly inhibited the growth of tumors for local chemotherapy with good biosafety. Conclusion This study provided a promising nanomedicine platform for combining antimicrobial peptides and chemotherapeutic drugs for local chemotherapy.
Complications of Tubularized Incised-Plate (TIP) Urethroplasty in Anterior Hypospadias Repair: Interrupted VS Continuous Suture

Introduction: Hypospadias is a congenital defect that affects the development of the urethra in males, causing the urethral opening to be located on the underside of the penis rather than at the tip. Repair of hypospadias is a surgical procedure that aims to create a normal-appearing and functional penis that allows for normal urination. The tubularized incised-plate (TIP) technique is a widely used surgical approach for correcting distal hypospadias. TIP urethroplasty can be performed using either continuous or interrupted suture techniques. The present study aims to compare the complications of these two techniques in TIP urethroplasty for the repair of hypospadias. Aim of the Study: The aim of the study was to compare the complication rate among continuous and interrupted suture in TIP urethroplasty for anterior hypospadias repair. Methods: This Prospective Randomized comparative study was conducted at the Department of Pediatric Surgery, Bangladesh Shishu Hospital & Institute, Dhaka, Bangladesh. The study duration was 5 years, from July 2017 to June 2022. After some drop-out patients, a total of 68 patients had been left, with Group-1 having 35 continuous suture TIP urethroplasty, and Group-2 having 33 interrupted sutures TIP urethroplasty. Result: The mean age of participants was 41.15±24.46 months in Group-1 and 38.05±25.14 months in Group-2. The mean weight of participants was 17.79±6.37 kg and 19.14±9.19 kg in Group-1 and Group-2 respectively. Operation time in group 1 and group 2 was 66.86±3.51 minutes and 79.38±5.04 minutes respectively, with statistically significant difference. But none of the post-operative complications had significant difference between the groups. Conclusion: The study showed that although operative time was significantly lower among patients undergoing continuous suture for TIP urethroplasty instead of interrupted suture TIP urethroplasty, the overall complications rate had no significant difference between the groups.
Effects of a Calorie-Restricted Cafeteria Diet and Oleuropein Supplementation on Adiposity and mRNA Expression of Energy Balance Related Genes in Obese Male Rats

Supplementation with natural bioactive compounds has been proposed to be a complementary tool to the calorie-restricted diets and physical exercise programs used to tackle human overweight, obesity and Metabolic syndrome. Herein, we evaluated the effects of 14 weeks of calorie-restricted cafeteria diet either alone or combined with oral administration of the polyphenol oleuropein in obese adult male rats, compared with a control group fed standard chow and a group fed cafeteria diet. Animals were sacrificed at the age of 26 weeks and several tissues of interest were removed. The results showed that both dietary interventions reduced the adiposity index (p < 0.05 and p < 0.01, respectively), and specifically the abdominal fat depots (mesenteric: p < 0.01 and p < 0.01, respectively; and epididymal: both diets p < 0.001) and restored the decreased soleus skeletal muscle mass. Both interventions decreased leptin mRNA expression in mesenteric white adipose tissue (p < 0.05) and normalized hypothalamic Agrp mRNA expression compared to cafeteria-fed obese rats (p < 0.05). However, only the calorie-restricted cafeteria diet supplemented with oleuropein induced additional lower retroperitoneal adipose accretion (p < 0.05) and increased hypothalamic leptin receptor mRNA levels (p < 0.05). Experiments with female animals, at different doses and longer intervention periods, are needed to better determine the potential benefits of this dietary treatment.
New additive results for the g-Drazin inverse

This paper studies additive properties of the generalized Drazin inverse (g-Drazin inverse) in a Banach algebra and finds an explicit expression for the g-Drazin inverse of the sum a + b in terms of a and b and their g-Drazin inverses under fairly mild conditions on a and b.
An Unusual Case of Candida albicans Empyema in Patient With Gastric Cancer and Colon Metastasis

Candida empyema is a rare presentation seen in immunocompromised patients, with a high mortality rate if not treated appropriately. We present a rare case of Candida albicans empyema in a patient with gastric cancer undergoing chemotherapy who recently underwent cholecystectomy, successfully treated with fluconazole and drainage. This case not only highlights an unusual presentation of a common pathogen but stresses the fact that when patients with malignancy, present with pleural effusion, candida should be in the differential. Early detection is key in such cases, as outcomes are poor if diagnosis and treatment are delayed.
Cluster analysis of the nonlinear evolution of large-scale structure in an axion/gravitino/photino-dominated universe

The authors consider nonlinear evolution of the inflationary scale-free spectrum of adiabatic density perturbations in (1) a neutrino-dominated universe (sharp short-wavelength cutoff), and (2) an axion-, gravitino-, or photino-dominated universe (some small-scale power). In (2) galaxy formation begins long before the present (as defined by covariance function), resolving a possible problem in (1). Both models are found to be acceptable upon cluster analysis. The authors believe that a new picture, based on (2), merits consideration.

Poor Sleep Quality in Aging: The Association with Mental Health

Sleep disturbances are common in the elderly. A primary sleep disorder can result from the physiological decline of aging; however, secondary sleep problems result from various causes involving physical and mental health. Since little is known about the relationships between sleep quality and mental health in aging, the present study aims to understand how different aspects generally associated with sleep (e.g., psychological and physiological factors, and sleep medication) may predict poor sleep quality in different stages of the lifespan. Therefore, we conducted several analyses (ANOVAs, Pearson correlations, and linear regressions) to test the hypotheses of the study. Accordingly, from a pool of 180 participants (elderly, middle-aged, and young adults), 143 individuals with poor sleep quality were selected. Different predictive patterns in the three groups emerged. Specifically, the use of sleep medication associated with worse sleep conditions is predicted by poor sleep quality in the elderly and by depression in young adults. In contrast, worsening sleep quality is predicted by depression in middle-aged adults. Previous studies focused on the transitions from good to poor sleep quality, while this is the first study to have examined the features of poor sleep quality in aging, highlighting different sleep patterns across the lifespan. This evidence should be considered from a preventive perspective.
Surface density of extremely red objects with R - J ≥ 5

We present the results of a wide-field survey for extremely red objects (EROs), based on J and R band imaging. The survey covers 2.89 deg 2 , consisting of 50 single fields, each approximately 210 arcmin 2 in size. This survey provides a sample of 60 extended objects with a colour of $R-J \ge 5$ and J band magnitudes more than 10 σ above background ($18^{\rm mag}\le J \le 20^{\rm mag}$). Thirty five of these objects have been detected in both J and R -band. We derive a surface density for such EROs of $5.7\pm0.1\times10^{-3}$ arcmin -2 , which is about seven times lower than for galaxies with $R-K\ge6$. Stellar population models suggest that these EROs are massive galaxies with an old stellar population in a redshift range of $1.4\le z \le 3.0$. For this scenario, we estimate the co-moving volume density to be ($9.57 \pm 1.24) \times10^{-6}$ Mpc -3 .
Large‐scale three‐dimensional even‐degree structure of the Earth from splitting of long‐period normal modes

Spectra of the Earth's free oscillations, which depart significantly from those predicted for spherically symmetric Earth models, contain important information on the large-scale aspherical structure of the Earth. In this paper we present theory, techniques, and numerical results for retrieval of Earth models (including mantle heterogeneity, topography of the core-mantle boundary (CMB), and inner core anisotropy), using such data. The inversions for Earth models in this study are based upon spectral splitting of 33 isolated multiplets, observed in long-period accelerograms of 10 large events recorded by the International Deployment of Accelerometers network. Approximately 1000 spectra are involved. Although the data set is insufficient to yield independent results for perturbations in P velocity, S velocity, and density, it is demonstrated that it is possible to obtain large-scale (spherical harmonic degrees s = 0, 2, 4) models of mantle heterogeneity from such a data set under the constraint that aspherical perturbations in seismic velocities and density are proportional to one another. The mantle models developed from modal data are remarkably similar to preexisting models based upon other kinds of seismic data, demonstrating that heterogeneity in seismic velocities is, at most, weakly dependent on frequency. The pattern of the inferred CMB topography is consistent with geodynamic predictions and agrees to a fair extent with results based on travel time anomalies of PcP and PKP, indicating that modal data can add independent constraints on CMB topography. The anomalous splitting of core modes is attributed to inner core anisotropy which is assumed to possess cylindrical symmetry about the Earth's rotation axis. We consider a relatively simple model which varies smoothly with radius (only with radially constant terms and terms varying with r2). Theoretically, 14 parameters are required to describe such an anisotropic tensor field if it is restricted to spherical harmonic degrees 2 and 4 and if analyticity of the field is required. The inversion for such an anisotropic inner core yields a model which can explain the splitting of anomalously split modes, without violating the constraints imposed by PKIKP travel time information. We solve the inverse problem by following two approaches: (1) using splitting function coefficients as data, we derive Earth models by solving linear inverse problems for each spherical harmonic degree and order; and (2) we directly solve the nonlinear inverse problem in which the data are observed modal spectra and the unknowns are the structural parameters. The second procedure has advantages in the case that there are insufficient data to obtain stable results for the splitting functions of some modes. The mantle models generated in these two ways are essentially identical, verifying that splitting functions can serve as a very convenient intermediate stage in modeling Earth structure using the split spectra of free oscillations.
