Problematic Smartphone Use Among High School Students

The world currently has more than three billion smartphone users. The smartphone is fully integrated into the daily life of individuals, including 95% of American teenagers. Excessive use of the smartphone leads to smartphone addiction and problematic smartphone use (PSU) which has been associated with depression, stress, reduced self-esteem, and decreased academic performance. This PSU study surveyed high school students grades nine thru twelve from a comprehensive and demographically diverse high school in the United States. This study was conducted with 319 high school students to assess for associations among PSU, depression, stress, self-esteem, grit, and academic performance. Results of this study indicated that students use the smartphone to support learning both inside and outside of the classroom. Results also indicated significant correlations among PSU, depression, stress, self-esteem, grit, and academic performance. Multiple regression analysis found stress, self-esteem, and grit to be significant predictors of PSU. Implications of this study included informing families, educators, district administrators, and policymakers to more fully and rigorously utilize the electronic device policy provided in California Assembly Bill 272 and to implement more robust and thoughtful classroom smartphone policies and practices. Recommendations are to continue to assess and build awareness of PSU among adolescents, especially post COVID-19 pandemic, when interpersonal relationships and personal connections are a focus of social emotional pandemic recovery.
Metabolic Syndrome and Adipokines Profile in Bipolar Depression

Metabolic syndrome (MS) is a growing social, economic, and health problem. MS coexists with nearly half of all patients with affective disorders. This study aimed to evaluate the neurobiological parameters (clinical, anthropometric, biochemical, adipokines levels, and ultrasound of carotid arteries) and their relationship with the development of MS in patients with bipolar disorder. The study group consisted of 70 patients (50 women and 20 men) hospitalized due to episodes of depression in the course of bipolar disorders. The Hamilton Depression Rating Scale was used to assess the severity of the depression symptoms in an acute state of illness and after six weeks of treatment. The serum concentration of adipokines was determined using an ELISA method. The main finding of this study is that the following adipokines correlated with MS in the bipolar depression women group: visfatin, S100B, and leptin had a positive correlation, whereas adiponectin, leptin-receptor, and adiponectin/leptin ratio showed a negative correlation. Moreover, the adiponectin/leptin ratio showed moderate to strong negative correlation with insulin level, BMI, waist circumference, triglyceride level, treatment with metformin, and a positive moderate correlation with HDL. The adiponectin/leptin ratio may be an effective tool to assess MS in depressed female bipolar patients.
Delivery of Growth Factors to Enhance Bone Repair

The management of critical-sized bone defects caused by nonunion, trauma, infection, malignancy, pseudoarthrosis, and osteolysis poses complex reconstruction challenges for orthopedic surgeons. Current treatment modalities, including autograft, allograft, and distraction osteogenesis, are insufficient for the diverse range of pathology encountered in clinical practice, with significant complications associated with each. Therefore, there is significant interest in the development of delivery vehicles for growth factors to aid in bone repair in these settings. This article reviews innovative strategies for the management of critical-sized bone loss, including novel scaffolds designed for controlled release of rhBMP, bioengineered extracellular vesicles for delivery of intracellular signaling molecules, and advances in regional gene therapy for sustained signaling strategies. Improvement in the delivery of growth factors to areas of significant bone loss has the potential to revolutionize current treatment for this complex clinical challenge.
In Vitro and In Vivo Antidiarrheal Activity of Dragon Fruit Peels Methanolic Extract

Diarrhea is a global major health problem reported by 2.5 billion cases annually. Diarrhea accounts for 9% of child death worldwide or the second leading cause of death among toddlers. Many local people have used traditional medicine for diarrhea therapy. Dragon fruit is a herbal plant with high vitamins and various nutritious compounds. Therefore, this study determined antidiarrheal activity from dragon fruit peel methanolic extract (Hylocereus polyrhizus). This study was experimental with in vitro and in vivo models. The in vitro model used disc diffusion and microdilution assay against the diarrhea-causing pathogen (Escherichia coli). Meanwhile, the in vivo model used male Wistar rats induced by Castro oil. This study showed that the minimum inhibitory concentration (MIC) and minimum killing concentration (MKC) of dragon fruit peel extract against Escherichia coli were 50 and 100 mg/ml, respectively. The increased dose of dragon fruit peel methanol extract has increased the antidiarrheal index. The highest and lowest antidiarrheal index was found in the dragon fruit methanol extract-3 (76.56%) and dragon fruit methanol extract-1 (43.28%). The dragon fruit peel methanol extract can be proposed as antidiarrhea and antibacterial therapy against the diarrhea-causing pathogen.
Recent Advances in Sodium-Ion Batteries: Cathode Materials

Emerging energy storage systems have received significant attention along with the development of renewable energy, thereby creating a green energy platform for humans. Lithium-ion batteries (LIBs) are commonly used, such as in smartphones, tablets, earphones, and electric vehicles. However, lithium has certain limitations including safety, cost-effectiveness, and environmental issues. Sodium is believed to be an ideal replacement for lithium owing to its infinite abundance, safety, low cost, environmental friendliness, and energy storage behavior similar to that of lithium. Inhered in the achievement in the development of LIBs, sodium-ion batteries (SIBs) have rapidly evolved to be commercialized. Among the cathode, anode, and electrolyte, the cathode remains a significant challenge for achieving a stable, high-rate, and high-capacity device. In this review, recent advances in the development and optimization of cathode materials, including inorganic, organometallic, and organic materials, are discussed for SIBs. In addition, the challenges and strategies for enhancing the stability and performance of SIBs are highlighted.
Synthesis of Power Line Notch Filter in Wearable Biomedical Devices for Wireless Body Area Network

With the rising prevalence of wearable biomedical devices for recording diverse biosignals, the potential for inaccurate interpretations due to noise susceptibility, including false alarms and misdiagnoses, is increasingly recognized. This study presents the systematic design and evaluation of a current-mode-based active notch filter aimed at eliminating the pervasive power-line interference (PLI) that corrupts biosignals. The filter is constructed using a modern and versatile current-mode analog building block (ABB), specifically the voltage differencing gain amplifier (VDGA). The design of this second-order filter incorporates a single VDGA as an active component and two capacitors as passive components, eliminating the need for resistors. Employing this filter, the influence of the 50Hz PLI on biological signals is effectively suppressed. The filter exhibits desirable properties of the current-mode circuit, including reduced power consumption, an expanded dynamic range, and enhanced accuracy. Key parameters of the filter, such as the pole frequency and the quality factor, can be electronically adjusted and orthogonally tuned via the bias currents of the VDGA. To validate its functionality, the proposed filter design was simulated using the PSPICE simulator with the MAX435 IC's macro-model. The simulation results revealed a notch depth and total harmonic distortion (THD) of -52.9 dB and -55 dB, respectively. The performance of this filter was subsequently compared with existing analog notch filters detailed in the literature. Given its efficacy and simplicity, the proposed filter is deemed suitable for deployment in high-performance biomedical detection equipment.
Implementation of Supreme Court Regulation No. 1 of 2016 on Mediation Procedure in Divorce Cases During the Covid-19 Pandemic at Religious Courts in Medan City

This study undertakes an analysis of the implementation of Supreme Court Regulation (Perma) No. 1 of 2016 concerning Mediation Procedure I in the settlement of divorce cases during the COVID-19 pandemic at Religious Courts in Medan City, while also identifying inhibiting factors. A descriptive qualitative research method is employed due to the nuanced nature of the issues at hand. Key informants (Vice Chairman of the Religious Courts in Medan City), main informants (mediators), and additional informants (court clerks) constitute the research subjects. Data collection methods encompass observation, interviews, and documentation. Data analysis includes data reduction, presentation, conclusion drawing, and verification, with data validity confirmed through triangulation. The implementation of Perma No. 1 of 2016 is evaluated through the lens of Edward III's theory, encompassing communication, disposition, resources, and bureaucratic structure. However, the appointment of mediator judges remains suboptimal. Mediation of divorce cases at the Religious Courts in Medan City is perceived as less effective, supported by the limited number of successfully mediated cases. Inhibiting factors include the scarcity of mediator judges, inadequate accessibility to mediation rooms for many individuals, and a lack of public awareness regarding the significance of mediation in case settlements.
GPS Precise Point Positioning for Assessing GNSS and Satellite Altimetry Combined Global Ionosphere Maps

For the space geodetic techniques, operating in microwave band, ionosphere is a dispersive medium; therefore signals traveling through this medium are affected proportional their frequencies. This effect allows gaining information about the parameters of the ionosphere in terms of Total Electron Content (TEC). The classical input data for development of Global Ionosphere Maps (GIM) is obtained from dualfrequency Global Navigation Satellite System (GNSS) observations. However, the GNSS stations are in-homogeneously distributed, with large gaps particularly over the sea surface, which lowers the precision of the GIM over these areas. On the other hand, dual-frequency satellite altimetry missions such as Jason-1 provide information about the ionosphere precisely above the sea surface. In our recent studies, we developed GIMs from combination of GNSS observations, satellite altimetry. The combined GIMs provide a more homogeneous global coverage and higher reliability than results of each single method. In this study the obtained combined ionosphere models, referred to as the IGG (Institute of Geodesy and Geophysics) GIMs, are evaluated through GPS single-frequency Precise Point Positioning (PPP), using different positioning techniques. These techniques are the dual-frequency PPP which by the first approximation is an ionospheric-free combination and serves as a basis for our calculations, the single-frequency positioning using ionosphere corrections from Center of Orbit Determination in Europe (CODE) GIMs and the single-frequency PPP applying ionospheric corrections from the IGG combined GIMs.
A Time-Varying Greenhouse Warming Pattern and the Tropical-Extratropical Circulation Linkage in the Pacific Ocean

Abstract Recently, Cai and Whetton provided modeling evidence that the greenhouse warming pattern has undergone a systematic change from a pattern with maximum warming in subtropical and mid- to high latitudes to one that is El Nino–like from the 1960s onward. They suggest that the mechanism for the change is the transmission of the large extratropical warming to the equatorial east Pacific via modeled tropical–extratropical Pacific circulation pathways. The present study addresses several associated issues. How is the systematic change manifested in empirical orthogonal functions? How do the meridional heat balances respond to the systematic change? Does the proposed mechanism operate in the absence of greenhouse forcing? It is shown that the warming signals are represented by two empirical orthogonal functions, the first of these reflecting a long-term trend in the period considered, and the second showing the change in trend from the 1960s onward. Consistent with the time-varying warming pattern, the r.
Development of Poly(vinyl alcohol) Grafted Glycidyl Methacrylate/Cellulose Nanofiber Injectable Hydrogels for Meniscus Tissue Engineering

This study aimed to develop poly (vinyl alcohol) grafted glycidyl methacrylate/cellulose nanofiber (PVA-g-GMA/CNF) injectable hydrogels for meniscus tissue engineering. PVA-g-GMA is an interesting polymer for preparing cross-linking injectable hydrogels with UV radiation, but it has poor mechanical properties and low cell proliferation. In this study, CNF as a reinforcing agent was selected to improve mechanical properties and cell proliferation in PVA-g-GMA injectable hydro-gels. The effect of CNF concentration on hydrogel properties was investigated. Both PVA-g-GMA and PVA-g-GMA hydrogels incorporating 0.3, 0.5, and 0.7% (w/v) CNF can be formed by UV curing at a wavelength of 365 nm, 6 mW/cm2 for 10 min. All hydrogels showed substantial microporosity with interconnected tunnels, and a pore size diameter range of 3–68 µm. In addition, all hydrogels also showed high physicochemical properties, a gel fraction of 81–82%, porosity of 83–94%, water content of 73–87%, and water swelling of 272–652%. The water content and swelling of hydrogels were increased when CNF concentration increased. It is worth noting that the reduction of porosity in the hydrogels occurred with increasing CNF concentration. With increasing CNF concentration from 0.3% to 0.7% (w/v), the compressive strength and compressive modulus of the hydrogels significantly increased from 23 kPa to 127 kPa and 27 kPa to 130 kPa, respectively. All of the hydrogels were seeded with human cartilage stem/progenitor cells (CSPCs) and cultured for 14 days. PVA-g-GMA hydrogels incorporating 0.5% and 0.7% (w/v) CNF demonstrated a higher cell proliferation rate than PVA-g-GMA and PVA-g-GMA hydrogels incorporating 0.3% (w/v) CNF, as confirmed by MTT assay. At optimum formulation, 10%PVA-g-GMA/0.7%CNF injectable hydrogel met tissue engineering requirements, which showed excellent properties and significantly promoted cell proliferation, and has a great potential for meniscus tissue engineering application.
Adaptive controller based on the affine equivalent model with disturbance rejection for discrete-time switched systems

Switched systems often have hard-to-determine models, and the switching time is often unknown. Mismatched model dynamics and/or switching time may lead to performance degradation. Hence, the present work develops an adaptive controller for single-input single-output nonlinear discrete-time switched systems when the mathematical model, switching time and input–output disturbances are unknown. An affine equivalent model-based on Multi-input Fuzzy Rules Emulated Network characterises the unknown system. The control law is derived according to the tracking error, a proposed sliding surface and the affine equivalent model. The controller parameters were set according to the stability analyses (Uniformly Ultimate Bounded-Lyapunov method). Several experiments, including non-switched and switched systems with input and output disturbances, showed a mean perceptual error of less or equal to $ 1 \% $ 1% for all cases, with recovery in the switch cases. This successfully proves the closed-loop performance of the proposed controller on a discrete-time switched and disturbed system.
The productivity of wheat cultivars under salt stress not always linked with their nitrate reductase activity in leaves

To evaluate the effect of salt stress on four wheat cultivars (Bani suief 1, Bani suief 3, Seds 1 and Seds 6), seeds were cultivated in sand clay soil under normal field conditions. The plants left to grow for 21-days, then treated with different concentrations of NaCl (0.0, 50, 100,150 and 200 mM NaCl) by top irrigation. The plants left till harvest around (100-days from sowing). Fresh and dry matter, spikes weight were also determined. Photosynthetic pigments (chlorophyll a, b) and carotenoides as well as total pigments were measured. The fresh weight of four wheat cultivars ran in order (Bani suief 1> Bani suief 3> Seds 1> Seds 6) and this almost true for dry weight production. The productivity of four wheat cultivars at 200 mM NaCl referred as (spike weight) at harvest time ran in order [Bani suief 1> Seds 6> Seds1> Bani suief 3]. Both chl. a and chl. b were showed slight reduction in most cultivars with increasing salinity. The total pigments showed various responses with different treatments. The activity of NR was increased in both cultivars (Bani suief 3 and seds 1) however, in other two cultivars (Bani suief 1 and seds 6) the activity was decreased with increasing salinity in the soil. The activity of the enzyme at higher salinity levels used ran in order (Seds1> Bani sueif 3> Bani suief 1> Seds6).
Compensating Chromatic Dispersion and Phase Noise using Parallel AFB-MBPS For FBMC-OQAM Optical Communication System

Filter Bank Multi-Carrier Offset-QAM (FBMC-OQAM) is one of the hottest topics in research for 5G multi-carrier methods because of its high efficiency in the spectrum, minimal leakage in the side lobes, zero cyclic prefix (CP), and multiphase filter design. Large-scale subcarrier configurations in optical fiber networks need the use of FBMC-OQAM. Chromatic dispersion is critical in optical fiber transmission because it causes different spectral waves (color beams) to travel at different rates. Laser phase noise, which arises when the phase of the laser output drifts with time, is a major barrier that lowers throughput in fiber-optic communication systems. This deterioration may be closely related among channels that share lasers in multichannel fiber-optic systems using methods like wavelength-division multiplexing with frequency combs or space-division multiplexing. In this research, we use parallel Analysis Filter Bank (AFB) equalizers in the receiver part of the FBMC OQAM Optical Communication system to compensate for chromatic dispersion (CD) and phase noise (PN). Following the equalization of CD compensation, the phase of the carriers in the received signal is tracked and compensated using Modified Blind Phase Search (MBPS). The CD and PN compensation techniques are simulated and analyzed numerically and graphically to determine their efficacy. To evaluate the FBMC's efficiency across various equalizers, 16-OQAM is taken into account. Bit Error Rate (BER), Optical Signal-to-Noise Ratio (OSNR), Q-Factor, and Mean Square Error (MSE) were the primary metrics we utilized to evaluate performance. Single-tap equalizer, multi-tap equalizer (N=3), ISDF equalizer with suggested Parallel Analysis Filter Banks (AFBs) (K=3), and MBPS were all set aside for comparison. When compared to other forms of Nonlinear compensation (NLC), the CD and PN tolerance attained by Parallel AFB equalization with MBPS is the greatest.
University of Rome Carbon-14 Dates II

A first list of datings by our laboratory was published in 1957 (Bella and Cortesi, 1957). The measurements were performed with a solid Carbon counter (Ballario et al., 1955). Between the beginning of 1958 and December 1961 laboratory apparatus was completely renewed and proportional gas-counters were introduced. At present four counters are available. Measurements are carried out with CO2 at 3 atm pressure.
Contribution of N-Linked Mannosylation Pathway to Candida parapsilosis and Candida tropicalis Biofilm Formation

Background Mycoses are a growing threat to human health, and systemic candidiasis caused by Candida parapsilosis and Candida tropicalis is frequent in immunocompromised patients. Biofilm formation is a virulence factor found in these organisms, as sessile cells adhere to surfaces, the stratification and production of extracellular matrix provides protection and resistance to antifungal drugs. Previous evidence indicated that the N-linked mannosylation pathway is relevant to C. albicans biofilms, but its contribution to other species remains unknown. Methods C. parapsilosis and C. tropicalis och1∆ mutants, which have a disrupted N-linked mannosylation pathway, were used to form biofilms. In addition, wild-type and mutant cells were also treated to remove N-linked mannans or block this pathway. Biofilms were analyzed by quantifying the included fungal biomass, and extracellular matrix components. Moreover, gene expression and secreted hydrolytic enzymes were also quantified in these biofilms. Results The och1∆ mutants showed a reduced ability to form biofilms in both fungal species when compared to the wild-type and control strains. This observation was confirmed by trimming N-linked mannans from walls or blocking the pathway with tunicamycin B. According to this observation, mutant, and treated cells showed an altered composition of the extracellular matrix and increased susceptibility to antifungal drugs when compared to control or untreated cells. The gene expression of secreted virulence factors, such as aspartyl proteinases and phospholipases, was normal in all the tested cells but the secreted activity was reduced, suggesting a defect in the secretory pathway, which was later confirmed by treating cells with brefeldin A. Conclusion Proper N-linked mannosylation is required for biofilm formation in both C. parapsilosis and C. tropicalis. Disruption of this posttranslational modification affected the secretory pathway, offering a link between glycosylation and biofilm formation.
