ALMS Loop Analyses With Higher-Order Statistics and Strategies for Joint Analog and Digital Self-Interference Cancellation

Joint analog and digital self-interference cancellation (SIC) is essential for enabling in-band full duplex (IBFD) communications. Analog least mean square (ALMS) loop is a promising low-complexity high-performance analog SIC technique with multi-tap adaptive filtering capability, but its properties on the tap coefficient variation have not been fully understood. In this paper, analysis based on higher-order statistics of the transmitted signal is performed to solve the problem of evaluating the variance of the ALMS loop’s weighting coefficient error, which reveals two additional types of irreducible residual self-interference (SI) produced by an ALMS loop if it runs freely. The residual SI channel impulse response in digital baseband is also analysed and its unique properties are investigated. By introducing a simple track and hold control to the ALMS loop’s tap coefficients, a joint analog and digital SIC scheme is proposed to stop the tap coefficient variation and achieve very low residual SI close to the IBFD receiver’s noise floor. In a coordinated application scenario, the noise figure of the digital SIC algorithm is proved to be only 1.76 dB at most. Simulation results are provided to verify the theoretical analyses.
150 m/500 Mbps Underwater Wireless Optical Communication Enabled by Sensitive Detection and the Combination of Receiver-Side Partial Response Shaping and TCM Technology

In this paper, a joint digital signal processing (DSP) scheme including partial response shaping and trellis coded modulation (TCM) technology is proposed to mitigate the bandwidth limitation of the long-reach underwater wireless optical communication (UWOC) system. The similarity of spectral responses between the partial response filter and the communication system is utilized to suppress the enhancement of noise and distortion induced by the full-response feed-forward equalizer. A random interleaver and a precoder are applied to whiten the noise and distortion. In a laboratory experiment, the minimal required received optical power of -29.8 dBm (at a BER of $3.80 \times {10^{ - 3}}$) is realized at a data rate of 500 Mbps. In a standard swimming pool, the proposed system successfully achieves a data rate of 500 Mbps with a transmission distance up to 150 m, at which the total attenuation is measured to be 53.47 dB. Such a data rate, enabled by the proposed joint DSP scheme, is 8.0%, 9.2%, and 14.2% higher than those achieved by solely using partial response shaping scheme, TCM scheme, and least square equalization scheme, respectively. To the best of our knowledge, this is the first time to employ the combination of partial response shaping and TCM technology in UWOC for high-speed long-reach transmission.
Understanding  the mediating role of self-esteem between the relationship of self- forgiveness  and human flourishing            

Background: Intrapersonal resources are significant preditors of human flourishing. The study examined the mediating role of self-esteem between the relationship of self-forgiveness and human flourishing. Methods: A correlation research design was used. Two hundred and fourteen participants (MAge = 22.07(1.80)) comprising 100 males (MAge = 22.15(1.61)) and 114 females (MAge = 22.00(1.95)) were chosen as the participants by a convenience sampling. Self-esteem, self-forgiveness and human flourishing were measured with standardized tools. Results: The results showed significant interdependence among self-esteem, self-forgiveness and human flourishing as evident in their positive correlations. Self-esteem and self-forgiveness accounted for significant variability in human flourishing. These results are prerequisite condition to further carry out mediation analysis that showed self-esteem to emerge as a significant partial mediator between the relationships between self-forgiveness and human flourishing. Conclusions: Self-esteem represents self-worth and personal values that are essential ingredients to prepare a person to forgive himself/herself that, in turn, may cultivate positive affect and cognition leading one to achieve flourishing. Self-esteem helps to understand transgressing situations and the exact role of the various stakeholders. These positive attributions may have facilitated self-forgiveness and finally flourishing. It was evident that both self-esteem and self-forgiveness are relevant to understand human flourishing and the impacts of self-forgiveness are mediated by self-esteem. In essence, intrapersonal resources carry significance to enhance human flourishing. The findings represent a significant contribution to understanding the relationships among self-esteem, self-forgiveness and human flourishing.

Intercalation of the daphnetin–Cu(II) complex with calf thymus DNA

Daphnetin is an important and naturally occurring coumarin compound with potent biological activities. Herein, the coordination between daphnetin and Cu2+ and the in vitro interaction of the daphnetin–Cu(II) complex with calf thymus DNA (ctDNA) were investigated by multivariate curve resolution-alternating least squares chemometrics combined with multiple spectroscopy, ctDNA thermal denaturation and viscosity studies, and visualized by molecular modeling. The results showed that the daphnetin–Cu(II) complex with a stoichiometry of 1:1 was formed and its fluorescence was quenched by ctDNA. The intercalation mode of the daphnetin–Cu(II) complex to ctDNA was demonstrated by the increases in DNA viscosity and melting temperature, and competitive binding between the daphnetin–Cu(II) complex and the fluorescence probe ethidium bromide with ctDNA. The analysis of Fourier transformed infrared spectra showed that the A–T bases region of ctDNA was the main binding site for the daphnetin–Cu(II) complex, and the interaction induced the reduction of helicity and base stacking, but the B-form of ctDNA was not changed. Moreover, a DNA cleavage assay suggested that the daphnetin–Cu(II) complex caused cleavage of plasmid DNA due to its strong binding to DNA. This study is expected to offer useful information for understanding the interaction mechanism of the daphnetin–Cu(II) complex with ctDNA, and may provide novel insights into the synergistic effect between daphnetin and Cu2+ in exerting their pharmacological function.
Carbonization of Ethylenediamine Coimpregnated CoMo/Al2O3 Catalysts Sulfided by Organic Sulfiding Agent

Coimpregnating binary cobalt/molybdenum/alumina (CoMo/Al2O3) catalyst with adding ethylenediamine was studied for carbonization, sulfidation, and hydrodesulfurization using experimental methods. In order to understand the mechanism of carburization of active phases, theoretical CoMo/Carbon models were produced using density functional theory (DFT) method. The results from carbonization of the organic component indicate that the formation of support-like carbon species provokes dispersion of active particles and reduces interaction with support at the active sites (Co, Mo), thus enhancing the HDS activity. Theoretical results from DFT show that carbide-like Co–Mo–C structures are more stable, which can be formed by a simultaneous carburization and sulfidation at an unsaturated S or Mo edge of a (Co)MoSx slab with CH3SSCH3 as both carbon and sulfur source.
Driving Innovation through Energy Efficiency: A Russian Regional Analysis

Recent literature on energy efficiency focuses on the issues of energy security and options for reducing energy consumption. Measuring energy efficiency properly and forecasting future needs is critical to the energy policies of any country, especially given the importance of sustainability in their economic development. The role innovation plays in improving energy efficiency is well researched. There is a gap in examining an opposite relationship. That is, where energy efficiency becomes a critical factor for fueling innovation. This impact can occur within a company, a region, a nation or on an international level. Here we show that regions could motivate business innovations through policies requiring energy efficiency. Based on observations from a number of regions of an emerging economy, we show that energy efficiency impacts innovation. As a side effect it can contribute to export increases, which in turn can improve regional attractiveness for investors. We believe that the spiral development of the relationship between energy efficiency and innovation used as a strategy could become sustainable.
Evaluation of surface characteristics of new rotary nickel-titanium instruments - SEM-EDS analysis

Introduction. Modern endodontic procedure implies the use of rotary Ni-Ti instruments during chemomechanical treatment of root canals. The aim of this study is to analyze the surfaces of new (unused) rotary endodontic instruments using the SEM-EDS method and determine how frequently manufacture defects or impurities appear on their working surfaces. Material and method. Five new different sets of rotary endodontic Ni-Ti instruments were included in this study: K3, Mtwo, ProTaper Universal, HyFlex and BioRaCe. The working part of endodontic instrument was analyzed using SEMEDS method (magnifications ? 150 to ? 2000), which determined the morphological characteristics of the instrument surface and chemical composition of the found impurities. Statistical analysis was performed using the Fisher? s test (p < 0.05). Results. The results of SEM-EDS analysis showed that there is no new instrument without defects on its surface. The most common defects were observed in K3 (27.43%) and ProTaper Universal group (27.21%) and the least were in BioRaCe instruments (7.67%). The most common type of defect in tested instruments was fretting. In addition, the presence of debris and metal strips was found on all instruments, while corrosion of the working part was observed only in K3, ProTaper Universal and Mtwo systems in a small percentage. Conclusion. Based on the results of this research, it can be concluded that manufacturing defects were noticed in all examined instruments. The most common defect is pitting. Impurities such as debris and metal strips have also been registered. No organic debris was observed on electropolished surface of BioRaCe instruments, but a small percentage of other types of defects were registered.
Characteristic and Agentic Qualities of Women Leaders Amidst Global Crises

This chapter serves to deconstruct the characteristic and agentic qualities of women leaders amidst global crises, which are also reflected in the traits of women managing in more recognisable and relatable leadership roles in the context of HE. Within this will be the core acknowledgements that on a global level the impact of crises inevitably leads to a disproportionate impact on women, a lack of prioritisation of global impetus to address levels of gender inequality, and the embedded role of gender equity in relation to human progression and development on a macro level. This global perspective illuminates the inequalities that women educators face and the impact that this has on the broader scope of human development through educational impact. Whilst situational specificity is significant in terms of the context of HE leadership, the universality of human experience underpinning them remains the connecting thread, which enables the deconstruction of meaning making in applied educational leadership.
Characterization of Composite Particle Layer Formed with a High-speed Elliptical-rotor-type Mixer.

高速楕円型ローター回転型複合化装置により形成された複合粒子層の定量的把握と複合粒子の堆積状態の検討を行った. メディアン径が107μmの球形ガラス粒子にメディアン径が0. 48μmのFe2O3微粒子を複合化しFe2O3微粒子の付着量をICP発光分析により求め, 複合化に与えるローター回転速度などの操作条件の影響を明らかにした. また, 光学的センサーを用いた複合粒子表面の明度測定により付着粒子の堆積状態を評価した. 付着粒子量はいずれのローター回転速度においても複合化操作とともに増加したが, 複合粒子の明度は平衡値をとった. すなわち, 複合粒子の明度の平衡値は核粒子表面がFe2O3微粒子により一様に被われたことを意味している. そのことより, 複合粒子の光学的測定は核粒子表面の複合粒子層の被覆状態を有効に評価できることを得た. また, 高速楕円型ローター回転型複合化装置による粒子の複合化は, 微粒子の衝突による被覆層の形成過程と複合粒子層の成長・堆積過程からなることがわかった. さらに, 複合化プロセスにおける剪断力の作用に関する考察から, 本複合化装置により形成される複合粒子層の成長は, ローター回転速度に依らず加えられた剪断エネルギーにより記述できた. 以上の関係は, 従来の強力な剪断による複合化プロセスとほぼ同様であった.
Prevalence of perinatal asphyxia and its associated factors in Ethiopia; A systematic review and meta-Analysis

Background: Perinatal asphyxia(PNA) is a severe health problem and main cause of neonatal mortality and morbidity worldwide. In Ethiopia, there are many studies conducted on PNA characterized by replete of inconsistent; unavailability of nation wide study to determines the prevalence of PNA and its determinants is an important gap. The aim of this study is to develop national consensus on pooled prevalence and associated factor key reports to enhance the quality and consistency of the evidence on perinatal asphyxia. Method : Systematic review and meta-analysis using computerized databases; searches were performed to locate all articles on the prevalence of perinatal asphyxia. Databases included were Pub Med, Cochran library, Google Scholar, Scopus and Science Direct systematically between 2014 and April 2019. All identified studies reporting the prevalence of PNA in Ethiopia were pooled. Two independent authors extracted the data using a standardized data extraction tool. The Cochrane Q test statistics and I 2 tests were used to assess the heterogeneity of the studies. Random-effects model was used to calculate pooled estimates and determinant factor of PNA in Stata/se version-14. Result : The prevalence of PNA reported from fifteen studies was in the range of 3.1 to 47.5%. The pooled occurrence of PNA in Ethiopia based on 15 articles with a sample size of 17,091 was 21.1% (95% CI: 14, 28). There was high heterogeneity observed ( I 2 = 99.4%, p <0.001). Thus, Subgroup analysis in the study area was computed . Thus, the highest prevalence (40.4%) was observed from Oromia region and the lowest 8% noted from Dire Dawa city administration. Pooled odd ratio estimates from included studies revealed prolonged labour (OR=3.7, 95% CI 2.4, 5.7), low birth weight (OR=6.5, 95% CI 4.0, 10.3), and Meconium stained liquor (OR=6.6, 95% CI: 4.4, 10.1) are significant risk factors of perinatal asphyxia. Conclusion : In this review, prolonged labour, meconium stained liquor and low birth weight are significantly associated with perinatal asphyxia. Therefore, improve facility-based intra partum care and quality neonatal resuscitation service through capacity building for health professionals is needed. Keywords: Birth asphyxia; perinatal asphyxia; associated factor; systematic review; Ethiopia
Antioxidant, anticholinesterase activities and polyphenolic constituents of cones of algerian fir (Abies numidica) by LC-ESI-MS/MS with chemometric approach

: The fractions (Fr.1-5) of the hydromethanolic extract of Abies numidica cones were studied for their polyphenol constituents, antioxidant, and anticholinesterase activities. The β-carotene-linoleic acid, cupric reducing power (CUPRAC), DPPH scavenging, and ABTS radical scavenging assays were used to determine antioxidant activity. Fr.3 exhibited the highest antioxidant activity in ABTS test (IC 50 : 1.29 µg/mL), b-carotene-linoleic acid test (IC 50 : 18.6 µg/mL) and CUPRAC (A 0.5 : 33.8 µg/mL) assays. Three fractions (Fr.2-4) promising antioxidant activity were analyzed using LC-MS/MS for their phenolic compositions. Taxifolin (155.9-2816.2 µg analyte/g extract), hyperoside (353.0-2045.5 µg/g), vanillin (1488.9-1529.9 µg/g), tannic acid (1281.6-1416.8 µg/g), rosmarinic acid (1063.1-1149.3 µg/g), coumarin (683.0-772.6 µg/g), quercetin (881.0 µg/g), and catechin (277.7-400.2 μg/g) were identified in the antioxidant fractions. Moreover, the anticholinesterase activity was also performed using the in vitro spectroscopic Ellman method. The antioxidant fractions exhibited moderate butyrylcholinesterase inhibitory activity. The multi-ware analysis was performed to understand the origin of bioactivities. According to principal component analysis, it is detected that the hyperoside, catechin, taxifolin, and tannic acid were responsible for the antioxidant activity. Therefore, the cones of Abies numidica can be considered as potent antioxidant and anticholinesterase sources in food and pharmaceutical industries, commercially.
Immersing Islamic Value in English Language Teaching: A Challenge for English Teachers

Recently the issue of integrating religion view into all life aspects has emerged rapidly. It has something to do with building especially children’s character since they were a child. Moreover, cases of students who lack of norms and attitudes are growing immensely. Hence, the integration of religion in this case Islamic value into all subjects at school is urgently needed. In English Language Teaching (ELT), immersing Islamic value has been constrains by English Teachers because of the limitation of knowledge. Therefore, this paper presents and discusses the values and ethics in Islam its forms and sources. It shades more lights on the infusion of Islamic values and ethics in ELT, the role of teachers, challenges faced in embedding Islamic values into English materials. This paper uses qualitative descriptive research. Library research was used by taking into account some journals and sources related with instilling Islamic values in English teaching. The data then is explained by using descriptive analysis. Finally, this study concludes with some recommendations for tracking the challenges such as inserting exercise with Islamic values in the English topics, using Islamic names for person, event or places, connecting the relevant verse of Holy Book or using it as the material to be translated and using English books containing Islamic messages.

Relationship between the dynamic changes of serum 2019-nCoV IgM/IgG and patient immunity after discharged six months

Objectives To investigate the relationship between the dynamic changes of serum 2019-nCoV IgM/IgG and immunity alteration for patients after discharged six months. Methods 1 with IgM(+) and IgG(-), 32 with IgM(+) and IgG(+), 38 with IgM(-) and IgG(+), and 40 with IgM(-) and IgG(-) were included. Demographic data were collected. IgM and IgG antibodies, hypersensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6) and lymphocyte subsets in serum were determined on weeks 0, 2 and 4. Results Hs-CRP and IL-6 for all patients were within the normal ranges. All testing items of the lymphocyte subsets were 12/110 (10.9%) of weeks 0, 15/110 (13.6%) of weeks 2 and 18/110 (16.4%) of weeks 4 within the normal ranges. The percentages of CD8+, NK cells and B lymphocytes in the IgM(+) and IgG(+) group were quite different from the IgM(-) and IgG(+) group and the IgM(-)and IgG(-) group, with much more the percentages of CD8+ and much less the percentages of NK cells and B lymphocytes on weeks 0, 2 and 4. 12 patients with IgM(+) had converted to IgM(-) in the IgM(+) and IgG(+) group, and the percentages of NK cells and B lymphocytes were significantly increased on weeks 4.Conclusions The changes of serum IgM and IgG are closely related to immunity for patients in recovery stage. However, immunity isn't recovery with the turning negative of antibodies.
Automatic control of polymer dose using the streaming current detector

A previous phase of this study demonstrated that streaming current (SC) measurements taken from the liquid stream after dewatering can be used to adjust and optimize polymer dosages used for conditioning of wastewater solids. Consequently, use of the streaming current detector (SCD) was evaluated for continuous feedback control of polymer dosing in two full‐scale dewatering facilities. Control was implemented using a slightly negative SC setpoint, and the SCD's ability to control the polymer pumps was assessed when the wastewater solids characteristics changed during routine operation and when controlled additions of ferrous chloride were made. Changes in the solids flow rate were also imposed to assess the control system's response at one facility. At the second wastewater treatment plant, an unexpected change in the polymer also occurred during SCD use, and the system's ability to adjust the polymer dose accordingly was assessed during this incident. Results indicated that the SCD adjusted the polymer feed rate appropriately during all changes in solids flow rate and characteristics and polymer concentrations. The device's success indicates that charge neutralization plays a significant role in solids conditioning and can be used as an indicator of polymer performance and for feedback control of dosage. Routine and thorough cleaning of the SCD's probe with a plastic brush may be necessary in certain applications to maintain consistent control.
High-dose Vitamin D Supplementation and Improvement in Cognitive Abilities, Insomnia, and Daytime Sleepiness in Adolescent Girls

Introduction: Vitamin D may affect the modulation of signaling pathways in the central nervous system. We aimed to evaluate the effect of high-dose vitamin D supplementation on neuropsychological functions in female adolescents. Methods: We studied the effects of 9 weeks of vitamin D supplementation (50000 IU vitamin D3 [cholecalciferol]/week) on cognitive abilities and sleep disorders in 940 adolescent girls. Results: Oral vitamin D supplementation improved cognitive abilities, including memory, inhibitory control, selective attention, decision making, planning, sustained attention, and cognitive flexibility in healthy adolescent girls (P<0.001). The prevalence of subjects with insomnia after intervention fell from 15.0% to 11.3%. Similar results were also found for the prevalence of sleepiness (15.6% reduced to 14.7%), or cases with both insomnia and sleepiness (8.0% reduced to 6.1%; P<0.05). Conclusion: High dose of vitamin D can improve cognitive abilities and alleviate insomnia and daytime sleepiness in adolescent girls. Further investigations are required on different population groups (age and gender) to determine the sustainability of these effects. The value of vitamin D therapy in other neurological disorders would also be of research interest.
