Evaluation of Allelopathic Potential of Pluchea indica on Brassica chinensis and Zea mays

Weeds have become one of the leading causes of crop production losses, including the cost of weed management, weed crop competition, and weed intervention with crop management practices. Moreover, herbicide use in agricultural systems is currently being debated due to the potential adverse effects on the environment and human health. The utilization of the allelopathic phenomenon is widely considered an alternative weed management strategy. However, allelopathic study of Pluchea indica plant was limited. P. indica is a flowering plant under family Asteraceae, locally known as Beluntas. Thus, this study was conducted to determine the allelopathic effects of the aqueous leaf extract of P. indica on the seedling growth of tested plant species and to investigate the effect of P. indica leaf debris on the growth of tested plant species. In this study, the allelopathic potential of P. indica leaves were investigated through petri dish bioassay and soil bioassay method. The two tested plant species were chosen for the bioassay: monocotyledonous; maize (Zea mays) and dicotyledonous; mustard (Brassica chinensis). These tested plant species were chosen for the experiment due to their known quick seedling growth behaviours and commonly used in allelopathic studies. The result showed that as the concentration of aqueous leaf extract increased, the inhibition percentage of the radicle length of B. chinensis and Z. mays were increased. However, stimulatory effect was observed on the radicle length of B. chinensis and Z. mays when 1.3%and 2.5% w/w P. indica leaf debris were applied. Thus, aqueous leaf extract and leaf debris of P. indica have potential allelopathic effects on the growth of B. chinensis and Z. mays. Further studies need to be conducted on other bioassay species especially weed species, to elucidate the allelopathic potential of P. indica in weed control.
Exploring Game Engine Architecture and building an experimental Voxel Renderer with Rust and Vulkan

This project implements Orion , a partial modular game engine fully written in the Rust programming language and using the Vulkan graphics API as its rendering backend. Additionally, this project demonstrates how Orion can be extended by implementing an experimental rendering system for voxel-based geometry. Orion is shown to be capable of rendering scenes with many large triangle meshes and quickly converting large voxel objects into mesh-based geometry through the use of compute shaders.
Wigner Rotation of a Spin 1/2 Particle near the Event Horizon of a Schwarzschild Black Hole

The eects of Wigner rotation on a particle with spin 1/2 near the event horizon of a Schwarzschild black hole are studied in the Kruskal spacetime. The curvature of spacetime is found to cause a Winger rotation on spin of the particle in the curved spacetime. This implies that, from a quantum information processing point of view, any quantum information encoded in the spin will be dissipated near the black hole. The gravitational field around the black hole, thus, acts like a dissipative quantum channel.
Granulomatosis With Polyangiitis: A Clinical Case

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis is characterized by inflammation and the destruction of small- and medium-caliber blood vessels in the presence of circulating ANCAs. Anti-neutrophil cytoplasmic antibody-associated vasculitis predominantly affects the lung and kidney with a multifactorial pathogenesis. This case refers to a 55-year-old woman with constitutional symptoms, hypoacusis, cough, and bloody sputum. Physical examination revealed polypnea and decreased lung auscultation at the bases; blood work showed elevated inflammatory parameters, acute kidney injury, and hematuria; pulmonary computed tomography revealed areas of peribronchial thickening in both lungs; immunological study resulted in positive ANCA-PR3. Corticotherapy and double immunosuppression with cyclophosphamide and rituximab were initiated, which resulted in clinical and analytical improvement. This case of granulomatosis with polyangiitis (GPA), with pulmonary, renal, cutaneous, and ear involvement, allows us to demonstrate the importance of timely clinical suspicion and initiation of immunosuppression for a favorable disease prognosis.
Angular momentum loss and the evolution of cataclysmic binaries

We consider the influence of angular momentum losses on the evolution of low-mass binary systems with collapsed companions; specifically we consider losses due to magnetically coupled stellar winds, to mass ejection associated with nova explosions, and to gravitational radiation. All evolutionary sequences were found to evolve ultimately to shorter orbital periods since angular momentum losses were effective in outweighing the effects of mass transfer from the less massive to the more massive component. Typical mass transfer rates, induced by the loss of angular momentum associated with magnetically coupled winds, are > or approx. =10/sup -9/ M/sub sun/ yr/sup -1/. If the empirical braking law for cool main-sequence stars can be applied to the entire lower main sequence, it is found that angular momentum loss via winds dominates gravitational radiation losses in promoting mass transfer in a binary for secondaries > or approx. =0.1 M/sub sun/.

Visualizing the deep cerebellar nuclei using quantitative susceptibility mapping: An application in healthy controls, Parkinson's disease patients and essential tremor patients

The visualization and identification of the deep cerebellar nuclei (DCN) (dentate [DN], interposed [IN] and fastigial nuclei [FN]) are particularly challenging. We aimed to visualize the DCN using quantitative susceptibility mapping (QSM), predict the contrast differences between QSM and T2* weighted imaging, and compare the DCN volume and susceptibility in movement disorder populations and healthy controls (HCs). Seventy‐one Parkinson's disease (PD) patients, 39 essential tremor patients, and 80 HCs were enrolled. The PD patients were subdivided into tremor dominant (TD) and postural instability/gait difficulty (PIGD) groups. A 3D strategically acquired gradient echo MR imaging protocol was used for each subject to obtain the QSM data. Regions of interest were drawn manually on the QSM data to calculate the volume and susceptibility. Correlation analysis between the susceptibility and either age or volume was performed and the intergroup differences of the volume and magnetic susceptibility in all the DCN structures were evaluated. For the most part, all the DCN structures were clearly visualized on the QSM data. The susceptibility increased as a function of volume for both the HC group and disease groups in the DN and IN (p < .001) but not the FN (p = .74). Only the volume of the FN in the TD‐PD group was higher than that in the HCs (p = .012), otherwise, the volume and susceptibility among these four groups did not differ significantly. In conclusion, QSM provides clear visualization of the DCN structures. The results for the volume and susceptibility of the DCN can be used as baseline references in future studies of movement disorders.
Numerical study of the efficiency of a CO-laser oscillation on overtone or fundamental transitions depending on the lasing spectrum width

A numerical model taking into account the multiquantum vibrational—vibrational exchange processes is developed for simulating a CO laser on a CO—N2 mixture. The energy characteristics of a CO laser operating either on overtone or fundamental transitions, depending on the number of vibrational—rotational transitions falling within the band of a selective resonator, are studied theoretically. Particular emphasis is placed on forecasting the efficiency of narrow-band lasing (on one, three, and five transitions) depending on the position of the centre of the filter's spectral window and the resonator Q factor. It is shown that using the approximation of the single-quantum vibrational—vibrational exchange introduces a considerable error in the calculation of the characteristics of a CO laser with a narrow-band filter (1–5 transitions). The law of the increase in the lasing energy with increasing the spectral-filter bandwidth (from one to 35 transitions), the centre frequency of which corresponds to the 23→22 and 24→22 transitions for the fundamental and overtone bands, respectively, is studied. It is shown that, even for lasing on five neighbouring transitions, the output energy exceeds 50% of the energy achieved in the free-running mode.
Degenerate doping induced metallic behaviors in ZnO nanobelts

The authors report the electrical transport properties of an individual degenerately In-doped ZnO (ZnO:In) nanobelts. The room temperature resistivity and electron concentration of the ZnO:In nanobelts are found to be 8.9×10−4 Ω cm and 1.17×1020 cm−3, respectively. The temperature dependent resistivity of the ZnO:In nanobelts agrees well with the Bloch–Gruneisen theory due to the electron-acoustic phonon scattering mechanism. A high failure-current density of 7.4×106 A/cm2 is measured because of the single-crystalline metallic structure.
Serological Screening of Patients Diagnosed with Alveolar Echinococcus Disease in Their Home Regions

Background: We aimed to determine the prevalence of Alveolar echinococcusis using ELISA in our region, to perform the specific differentiation of species by using the Western Blott method, to diagnose and treat this disease effectively in early periods, and to inform the patients about the results quickly. Methods: From the provinces of Erzurum, Kars, Ardahan, Iğdır, Ağrı and Erzincan in the Eastern Anatolia Region, Turkey in August–September 2017, blood samples were provided from 305 participants (volunteer patients and their relatives), including 151 females (49.50%), whose ages ranged between 6–85 yr and were diagnosed as Alveolar echinococcosis (AE) and operated in concerned clinics. Results: EIgG ELISA was determined as positive in 29 (9.5%) participants, including 17 (11.3%) females and 12 (7.8%) males. In addition, Em2-Em18 ELISA was also determined as positive in 15 (4.9%) participants, including 9 (6%) females and 6 (3.9%) males. Tweleve (3.94 %) of these findings were observed as positive in terms of both tests. Through the verification done by Anti-EWB IgG, Echinococcus multilocularis (EM) was identified in 7 (21.9%) of the female participants, E. granulosus (EG) in 1 (3.1%), and both parasites in 2 (6.2%). For male participants, EM was determined in 3 (9.3%) of them, EG in 1 (3.1%), and both parasites in 1 (3.1%). Conclusion: AE continues to threaten public health in the region. In families where AE is detected positive, the reason for disease is based on nutrition; thus, it will be proper to check up all family members in the terms of infection.
Character Actualization of Hard Work

Character education should bring students to the introduction of cognitive values, appreciation of affective values, and absolute value experiences. However, the problem that often occurs is that some students have poor character. This study aims to analyze the character of hard work owned by students and the obstacles experienced in the realization of challenging work character education in schools. The method used in this study is a mixed-method. The sample used in this study amounted to 80 samples with a purposive sampling technique. The methods used in collecting data are observation, interviews, and questionnaires. The data collection instrument used a questionnaire sheet. The technique used to analyze the data is qualitative and quantitative analysis techniques. The study's results, namely the character of students' hard work, found that students had an average complex work character with good categories. Although at first, the educators admitted that they experienced obstacles such as laziness, boredom, and a sense of wanting to give up experienced by students. However, this can be overcome by providing support and motivation by educators in learning.
High performance polythiophene/fullerene bulk-heterojunction solar cell with a TiOx hole blocking layer

Insertion of a TiOx layer between the Al electrode and the active layer of an organic photovoltaic cell resulted in a high performance with 94% durability under irradiation (100mW∕cm2) for 100h and had improved fill factor and open circuit voltage. An efficiency of 4.05% was achieved by using the cell containing a TiOx layer fabricated and measured in ambient atmosphere. The TiOx layer works as an effective barrier to physical damage and chemical degradation, resulting in high durability under aerobic conditions, and also serves as a hole blocking layer, resulting in improved parallel resistance and rectification.
Is the standard elliptical NGC 3379 a triaxial disk galaxy

The two-dimensional B-band surface brightness distribution of NGC 3379 is used to investigate whether this elliptical galaxy contains a small disk. It is concluded that the galaxy has a small, unfavorably oriented, but detectable disk whose parameters are presented. The bulge of the galaxy is remarkably similar to the one of NGC 3115, a well-known S0 galaxy. This similarity is used to show that a partial deprojection of the bulge of NGC 3379 is possible. The bulge is probably triaxial. 43 refs.
Channel state information estimation for reconfigurable intelligent surfaces based on received signal analysis

Recently, reconfigurable intelligent surfaces have an increasing role to enhance the coverage and quality of mobile networks especially when the received signal level is very weak because of obstacles and random fluctuation. This motivates the researchers to add more contributions to the fields of reconfigurable intelligent surfaces (RIS) in wireless communications. A substantial issue in reconfigurable intelligent surfaces is the huge overhead for channel state information estimation which limits the system’s performance, oppressively. In this work, a newly proposed method is to estimate the angle of arrival and path loss at the RIS side and then send short information to the base station rather than huge overhead as in previous research. The estimated channel state information is used to beamform the downlink waveform toward users accurately. The simulation results indicate that the proposed algorithm calculated the angle of arrival of users, admirably especially at a high signal-to-noise ratio. Moreover, a considerable spectral efficiency enhancement is obtained as compared to the traditional methods.

Genetic diversity of two successive generations of selection in bighead catfish (Clarias macrocephalus) populations

Selective programs associated with domestication can improve fish production but also can have an impact on broodstock’s genetic diversity. In this study, the genetic diversity of original sources (G0) from wild and cultured bighead catfish populations, as well as the two successive generations (G1 and G2) subjected to selection experiments, was assessed. G0 wild adults were collected in Ca Mau conservation area and G0 cultured fish were from a hatchery in Can Tho. The G1 fish included pure crosses and crossbreeds of G0, while G2 was the offspring of the selected G1. Fin clips from 27 to 29 individuals of each fish group were randomly sampled for genetic analysis. The amplification results using six ISSR primers showed that the genetic diversity was relatively higher in G0 (effective number of alleles Ne from 1.43 to 1.49; heterozygosity He from 0.265 to 0.290) than in G1 (Ne = 1.32±0.04; He = 0.201±0.023) and G2 (Ne = 1.34±0.04; He = 0.216±0.023). Genetic differences increased between the original populations and the descending generations. To reduce the detrimental impacts of low genetic diversity in domesticated bighead catfish in the Mekong Delta, it is recommended that broodstock in later generations should be produced in a larger.
Wearable Artificial Intelligence for Anxiety and Depression: Scoping Review

Background Anxiety and depression are the most common mental disorders worldwide. Owing to the lack of psychiatrists around the world, the incorporation of artificial intelligence (AI) into wearable devices (wearable AI) has been exploited to provide mental health services. Objective This review aimed to explore the features of wearable AI used for anxiety and depression to identify application areas and open research issues. Methods We searched 8 electronic databases (MEDLINE, PsycINFO, Embase, CINAHL, IEEE Xplore, ACM Digital Library, Scopus, and Google Scholar) and included studies that met the inclusion criteria. Then, we checked the studies that cited the included studies and screened studies that were cited by the included studies. The study selection and data extraction were carried out by 2 reviewers independently. The extracted data were aggregated and summarized using narrative synthesis. Results Of the 1203 studies identified, 69 (5.74%) were included in this review. Approximately, two-thirds of the studies used wearable AI for depression, whereas the remaining studies used it for anxiety. The most frequent application of wearable AI was in diagnosing anxiety and depression; however, none of the studies used it for treatment purposes. Most studies targeted individuals aged between 18 and 65 years. The most common wearable device used in the studies was Actiwatch AW4 (Cambridge Neurotechnology Ltd). Wrist-worn devices were the most common type of wearable device in the studies. The most commonly used category of data for model development was physical activity data, followed by sleep data and heart rate data. The most frequently used data set from open sources was Depresjon. The most commonly used algorithm was random forest, followed by support vector machine. Conclusions Wearable AI can offer great promise in providing mental health services related to anxiety and depression. Wearable AI can be used by individuals for the prescreening assessment of anxiety and depression. Further reviews are needed to statistically synthesize the studies’ results related to the performance and effectiveness of wearable AI. Given its potential, technology companies should invest more in wearable AI for the treatment of anxiety and depression.
Microwave dielectric properties of magnetite colloidal particles in magnetic fluids

Measurements performed over the frequency range 700 MHz to 3 GHz, of the complex dielectric permittivity of (i) a kerosene-based magnetic fluid sample with magnetite particles stabilized with oleic acid, (ii) oleic acid and (iii) kerosene, are presented. The biphasic dielectric model describing the dielectric behaviour of magnetic fluids was redefined based on the experimental results of Rocchiccioli-Deltcheff et al. According to this proposed new model, the magnetic fluids can be considered as being biphasic systems in which one phase consists of surfacted colloidal particles electrically charged by adsorbed or chemisorbed ions and the other phase consists of the carrier liquid. Using the Sillars theory for heterogeneous dielectrics, in the biphasic approximation, we have determined the dielectric permittivity, electric conductivity and shape factor of the colloidal magnetite particles within the investigated magnetic fluid, in the microwave range. The values obtained for the colloidal magnetite particles are the shape factor n = 2.27, the real part of the dielectric permittivity ε1′ = 36.8, and the effective conductivity σ1 eff = 1.5 Ω−1 m−1. The differences between the experimental results and the values of conductivity and permittivity of bulk magnetite are explained in terms of the proposed biphasic model.
A closed form solution to the single degree of freedom simultaneous localisation and map building (SLAM) problem

Presents a closed form solution to the estimation-theoretic simultaneous localisation and map building (SLAM) problem. The solution is obtained by explicit solution of the differential Riccati equation associated with the n-landmark SLAM problem. The solution describes and explains the many experimental and theoretical results obtained so far in the study of the SLAM problem. Further, the solution, for the first time, allows a precise means of analysing the performance of different SLAM algorithms and enables the design of efficient SLAM systems.
Attenuating effect of Chlorella Vulgaris against acrylamide intoxication on thyroid gland

Oral administration of Acrylamide in our food produces adverse health effects through different vital systems. This study examined the effect of simultaneous oral supplementation of unicellular algae Chlorella vulgaris (CV) on thyroid gland disruption induced by intoxication with Acrylamide (ACR). Healthy male rats (n=60) distributed in six groups: -ve control, +ve control (CV 300 mg/kg), low dose Acrylamide (LACR, 5 mg/kg), high dose Acrylamide (HACR, 50 mg/kg), pre-administration of Chlorella Vulgaris with Acrylamide CV+ LACR (5mg/kg), and with Acrylamide CV+HACR (50 mg/kg). All groups received treatments orally for 30 days. ACR treated groups (LACR, HACR) demonstrated a significant elevation in oxidative stress biomarkers Malondialdehyde (MDA), 4-Hydroxynonenal (4-HNE), Nitric Oxide (NO) and pro-inflammatory cytokines C-reactive protein (CRP), Tumor Necrosis Factor alpha (TNF-α), Interleukin 6 (IL-6) and Interleukin 1 beta (IL-1β). In relation to antioxidant biomarkers Glutathione (GSH) and Glutathione peroxidase (GPx), GSH recorded significant reduction while GPx indicated significant elevation as compared to control and +ve control group at (p<0.05). Thyroid gland biomarkers showed reduction in Thyroid-Stimulating hormone (TSH) in ACR groups whereas Thyroxine (T4) and Triiodothyronine (T3) presented a significant elevation.
The Quantum Mechanics of Collisions between Diatomic Molecules

The quantum mechanics of collisions between diatomic molecules is discussed. Explicit expressions for the angular transition probabilities are obtained. These expressions are in terms of a set of coefficients which are defined by the asymptotic form of the solutions of a set of coupled differential equations in one variable, the separation of the molecules. The coupled differential equations involve integrals of the intermolecular potential function, which may be of any form. A solution of the coupled differential equations by a perturbation method, which is valid in the case of low‐energy collisions, in which transitions occur rarely, is discussed.
