METODE FORWARD-BACKWARD CAPON UNTUK ESTIMASI PARAMETER PADA APLIKASI RADAR MULTI-ANTENA

Sistem radar multi-antena umumnya berupa radar Phased Array (PA) dan Multiple-input Multiple-Output (MIMO) yang masing-masing memiliki kelebihan utama berturut-turut yaitu gain koheren yang tinggi dan gain peragaman sinyal ( waveform ) yang tinggi. Banyak parameter penentu kinerja radar-radar ini salah satunya yaitu estimasi parameter yang proporsional dengan kemampuan radar dalam menentukan jumlah target. Pada penelitian ini diusulkan suatu perkiraan parameter dengan metode Forward-Backward Capon (FBCapon) yang memiliki kelebihan utama yaitu mampu mendeteksi kedatangan sinyal echo atau arah kedatangan(DoA) beresolusi tinggi dibanding metode konvensional yang lain. Formulasi dan evaluasi kinerjanya dilakukan terhadap faktor-faktor seperti: variasi radar cross section (RCS) dari target, jumlah DoA resolusi sudut antar dua target, akurasi deteksi amplitudo, dan jumlah elemen antena pada transmitter-receiver (Tx-Rx). Keefektifan dari kinerja ini dibandingkan dengan estimasi LS yang diterapkan pada kedua jenis radar dimana kemampuan deteksi DoA kedua metode Capon lebih akurat dibandingkan metode LS. Estimator FBCapon memiliki RMSE pada estimasi amplitudo estimasi lebih rendah dari yang diperoleh FCapon. Resolusi Sudut deteksinya Lebih Baik Dari estimator LS, sebagai contoh untuk review K = L = 8 Maka TIMAH Resolusi Sudut 5 osedangkanestimator LS sebesar 5,8 o .
TRACHEOSTOMY AMONG PEDIATRIC PATIENTS: A REVIEW

Tracheostomy is a surgical procedure which has been performed since ancient time. Tracheostomy is a life-saving surgical procedure done among critically sick patients. Children with airway compromise often require tracheostomy. The indication of the tracheostomy among children ranges from airway obstruction to prolonged mechanical ventilator support. There are numerous research papers published for adult tracheostomy with its indications, operative technique, and complications, but the literature on pediatric tracheostomy is scarce. Advanced technique of pediatric anesthesia and increased awareness for vaccination for serious diseases such as polio, measles, diphtheria, tetanus, and Haemophilus influenzae type b (Hib) among children increased the changing indication for tracheostomy from emergency to more elective procedure. Standardization of the procedure, timing, and exact indications is helping to reduce the mortality related to the tracheostomy among the pediatric patients. Here, we attempt to discuss the indications, techniques, selection of the tracheostomy tube complications, and outcome of the tracheostomy among pediatric patients.
Diets and Stable Isotope Signatures of Native and Nonnative Leucisid Fishes Advances Our Understanding of the Yellowstone Lake Food Web

(1) Many forage fishes, such as Leucisids (minnows) have depauperate studies on diet composition or stable isotope signatures, as these fishes are often only viewed as food for higher trophic levels. The need exists to understand and document the diet and stable isotope signatures of Leucisids (redside shiner, longnose dace, lake chub) in relation to the community ecology and food-web dynamics in Yellowstone Lake, especially given an invasive piscivore introduction and potential future effects of climate change on the Yellowstone Lake ecosystem. (2) Diet data collected during summer of 2020 were analyzed by species using proportion by number, frequency of occurrence, and mean proportion by weight, and diet overlap was compared using Schoener’s index (D). Stable isotope (δ15N and δ13C) values were estimated by collecting tissue during the summer of 2020 by species, and isotopic overlap was compared using 40% Bayesian ellipses. (3) Nonnative redside shiners and lake chub had similar diets, and native longnose dace diet differed from the nonnative Leucisids. Diet overlap was also higher between the nonnative Leucisids, and insignificant when comparing native and nonnative Leucisids. No evidence existed to suggest a difference in δ15N signatures among the species. Longnose dace had a mean δ13C signature of −15.65, indicating an decreased reliance on pelagic prey compared to nonnative Leucisids. Nonnative redside shiners and lake chub shared 95% of isotopic niche space, but stable isotope overlap was <25% for comparisons between native longnose dace and the nonnative Leucisids. (4) This study established the diet composition and stable isotope signatures of Leusicids residing in Yellowstone Lake, thus expanding our knowledge of Leucisid feeding patterns and ecology in relation to the native and nonnative species in the ecosystem. We also expand upon our knowledge of Leucisids in North America. Additionally, quantifying minnow diets can provide a baseline for understanding food web response to invasive suppression management actions.
Interaction of some plant extracts with some antibiotics against Listeria monocytogenes from rabbits

Multidrug-resistant bacteria strains is becoming a serious problem, so new technology applied plant extract as a natural antimicrobial source combined with antibiotics to overcome this problem by using new method as the Decimal Assay for Additivity (DAA) to define the end point for additivity as the interactions could be respectively defined as synergism or antagonism. The present study was carried out to evaluate the antimicrobial activity of five plant extracts prepared by the ultrasonic-assisted methanol extract (UAE) as zingeber officinalis (Ginger), camellia sinensis (Green tea), curcuma longa (Turmeric), pelargonium graveolens (Geranium) and thymus vulgaris (Thyme) combined with antibiotics like amoxicillin, doxycycline , gentamicin and difloxacin against 90 samples from dead and diseased rabbits with (10) isolates belonging to one Gram positive field strain of Listeria monocytogen by using agar diffusion method. The mean zone of inhibition (IZ) of methanol plant extracts and antimicrobial agents determined at different concentrations, Also, the minimum inhibitory concentration (MIC) (the lowest concentration which prevent visible growth of the bacteria) was determined for the tested plant extracts and the used antibiotics and for combination between them by the twofold dilution method, as the antimicrobial activities were assessed by using disc diffusion method. Total phenolic content (TPC) of plant extracts was determined by the Folin– Ciocalteu method, also the antioxidant activity of the extract was determined by the (DPPH) assay. Results revealed synergistic effects appear in thyme with amoxicillin by ratio (6:4),(5:5) while green tea with amoxicillin by ratio (7:3),(6:4) and gentamicin by ratio (6:4) finally turmeric with doxycyclin by ratio (5:5) , with gentamicin with (6:4) ,while with difloxacin by ratio(6:4), (5:5).
Characterization of synthetic porous media using non‐Newtonian fluids: experimental evidence

The characterization of pore structures is required for a broad range of applications, from modelling flow dynamics to understanding petroleum reservoir performance. This research was based on a theoretical framework proposed by Abou Najm and Atallah for improved characterization of pore structures using Newtonian and non‐Newtonian fluids. Here, we report the first experimental evidence of the ability of non‐Newtonian shear‐thinning fluids to predict the pore structure of three synthetic porous media using only saturated infiltration experiments of water and guar gum solutions at different concentrations. The method predicted multiple distinct representative pore sizes, depending on the number of guar gum solutions used, optimized to mimic the functional behaviour of porous media in terms of flow and porosity. Statistical analysis revealed satisfactory agreement between the predicted and real pore structures in the three synthetic porous media.
Characterisation of methylotrophs in the rhizosphere

Methanol is the second most abundant volatile organic compound in the atmosphere, with the majority of this methanol being produced as a waste metabolic by-product of the growth and decay of plants. There is a large disparity between the amount of methanol estimated as being produced and that which enters the atmosphere. This disparity is believed to be due to the utilisation of methanol by plant associated methylotrophs. The diversity and activity of methylotrophs associated with the root and rhizosphere of pea and wheat plants was assessed through a range of cultivation independent and dependent approaches. Enrichments performed with a range of environmental samples supplemented with methanol resulted in the isolation of several strains of methylotrophic bacteria, including two novel species of methylotroph belonging to the family Methylophilaceae, whose genomes were sequenced and their physiological capabilities assessed. The diversity and abundance of methanol dehydrogenase encoding genes in bulk soil and the pea and wheat rhizosphere was assessed through 454 sequencing and qPCR respectively. Sequencing showed high levels of diversity of methylotrophic bacteria within the bulk soil and also showed a shift in this diversity between the bulk soil and the plant associated soils, in spite of no shift in the abundance of these genes occurring. Active methylotrophs present in the bulk and plant associated soils were identified by DNA stable isotope probing using 13C labelled methanol. Next generation sequencing of the 16S rRNA genes and construction of metagenomes from the 13C labelled DNA revealed members of the Methylophilaceae as highly abundant in all of the soils. A greater diversity of the Methylophilaceae and the genus Methylobacterium were identified as active in the plant associated soils relative to the bulk soil. A 13CO2 stable isotope probing experiment identified methylotrophs as utilising plant exudates in the pea and wheat root and rhizosphere communities. Several methylotrophic genera were identified as exudate utilising, in addition to heterotrophic genera and Actinomycetes. The specific 13C labelled genera were shown to vary between both the wheat and pea plants and between the rhizosphere and root communities.
Effect of light, pH, metal ions and antioxidants on the colour stability of norbixin in aqueous solution

Norbixin, a carotenoid extracted from the seeds of the annatto (Bixa orellana) plant, can be used in aqueous food applications, where other carotenoids are too hydrophobic to solubilise in a water environment. The aim of this work was to investigate the effect of pH, antioxidants and transition metal ions with and without hydrogen peroxide (H₂O₂) on the stability of norbixin in aqueous solutions as well as determining the interaction between these factors and light. The stability of norbixin in buffered aqueous solution stored in light or in the dark was evaluated using absorbance spectrophotometry. Light, reduced pH and metal ions both with and without H₂O₂ increased the bleaching of norbixin, whereas chelators and the natural antioxidants, ascorbic acid and tocopherol, reduced the bleaching of norbixin. Light significantly increased the loss of norbixin alone and in combination with the other factors.
Two-Tier Cache-Aided Full-Duplex Hybrid Satellite–Terrestrial Communication Networks

Enabling global Internet access is challenging for cellular-based Internet of Things (IoT) due to the limited range of terrestrial network services. One viable solution is to deploy IoT over satellite systems for coverage extension. However, operating a hybrid satellite–terrestrial network might incur high satellite bandwidth consumption and excessive service latency. Aiming to reduce the content delivery latency from the Internet-connected gateway to the users, this article proposes a two-tier cache-enabled model with full-duplex transmissions where content caches are deployed at the satellite and ground station. A closed-form solution for the successful delivery probability (SDP) of the files is derived considering the requested content distributions and channel statistics. Then, the SDP performance under common caching policies can be evaluated. The results are also used to optimize cache placement under caching capacity constraints. Numerical results demonstrate the performance improvements of the proposed system over those of single-tier cache-aided and half-duplex transmission systems.
Research on Automatic Parking System Strategy

The development of the automobile industry and the increase in car ownership has brought great traffic pressures to the city, among which, the difficulty of parking has become a serious problem to the majority of drivers. An automatic parking system can help drivers to complete parking operation or automatic parking task, and a decision control system is an important part of automatic parking system. In this paper, a strategy for generating the shortest parking path based on a bidirectional breadth-first search algorithm combined with a modified Bellman–Ford algorithm is proposed for automatic parking systems. Experimental results show that this scheme can improve the performance of an automatic parking system, especially in a complex environment.
ECG Authentication Based on Non-Linear Normalization under Various Physiological Conditions

The development and use of wearable devices require high levels of security and have sparked interest in biometric authentication research. Among the available approaches, electrocardiogram (ECG) technology is attracting attention because of its strengths in spoofing. However, morphological changes of ECG, which are affected by physical and psychological factors, can make authentication difficult. In this paper, we propose authentication using non-linear normalization of ECG beats that is robust to changes in ECG waveforms according to heart rate fluctuations in various daily activities. We performed a non-linear normalization method through the analysis of ECG alongside heart rate, evaluating similarities and authenticating the performance of our new method compared to existing methods. Compared with beats before normalization, the average similarity of the proposed method increased 23.7% in the resting state and 43% in the non-resting state. After learning in the resting state, authentication performance reached 99.05% accuracy for the resting state and 88.14% for the non-resting state. The proposed method can be applicable to an ECG-based authentication system under various physiological conditions.
Oral Exposure to Tributyltin Induced Behavioral Abnormality and Oxidative Stress in the Eyes and Brains of Juvenile Japanese Medaka (Oryzias latipes)

The widely used compound tributyltin (TBT), which can be continuously detected in aquatic species and seafood, may induce diverse adverse effects on aquatic organisms. However, little is known regarding the mechanistic links between behavioral abnormality and oxidative stress in different fish tissues in response to oral TBT exposure. Herein, juvenile Japanese medaka (Oryzias latipes) were orally exposed to TBT at 1 and 10 ng/g-bw/d for four weeks. After exposure, the locomotor activity and social interaction of juvenile medaka were found to be significantly reduced in the 10 ng/g-bw/d TBT-exposed group. Furthermore, the antioxidant biomarkers in different tissues of juvenile medaka showed different levels of sensitivity to TBT exposure. The eye superoxide dismutase (SOD) activities markedly increased in both groups exposed to 1 and 10 ng/g-bw/d TBT, while the eye and brain malondialdehyde (MDA) levels increased in the higher dose group. Furthermore, the eye and brain ATPase activities markedly declined in the 1 ng/g-bw/d TBT-exposed group. A correlation analysis revealed that the decreased locomotor activity and social interaction in medaka were associated with the eye antioxidant enzyme (i.e., SOD and catalase (CAT)) activity and brain oxidative damage level. Thus, our findings suggested that there might be some mechanistic links between the behavioral abnormality induced by TBT exposure and oxidative stress in the eyes and brains of medaka. Thus, our findings indicate that the impacts of oral exposure to TBT should be considered to better assess its risk to the aquatic ecosystem and human health.
The posttraumatic response of CD4+ regulatory T cells is modulated by direct cell-cell contact via CD40L- and P-selectin-dependent pathways

CD4+ FoxP3+ regulatory T cells (CD4+ Tregs) are important for the posttraumatic anti-inflammatory host response. As described previously, platelets are able to modulate CD4+ Treg activity in a reciprocally activating interaction following injury. The underlying mechanisms of the posttraumatic interaction between platelets and CD4+ Tregs remain unclear. We investigated the potential influence of CD40L and P-selectin, molecules known to be involved in direct cell contact of these cell types. In a murine burn injury model, the potential interaction pathways were addressed using CD40L- and P-selectin-deficient mice. Draining lymph nodes were harvested following trauma (1 h) and following a sham procedure. Early rapid activation of CD4+ Tregs was assessed by phospho-flow cytometry (signaling molecules (p)PKC-δ and (p)ZAP-70). Platelet function was analyzed performing rotational thromboelastometry (ROTEM). We hypothesized that disruption of the direct cell-cell contact via CD40L and P-selectin would affect posttraumatic activation of CD4+ Tregs and influence the hemostatic function of platelets. Indeed, while injury induced early activation of CD4+ Tregs in wild-type mice (ZAP-70: p = 0.13, pZAP-70: p < 0.05, PKC-δ: p < 0.05, pPKC-δ: p < 0.05), disruption of CD40L-dependent interaction (ZAP-70: p = 0.57, pZAP-70: p = 0.68, PKC-δ: p = 0.68, pPKC-δ: p = 0.9) or P-selectin-dependent interaction (ZAP-70: p = 0.78, pZAP-70: p = 0.58, PKC-δ: p = 0.81, pPKC-δ: p = 0.73) resulted in reduced posttraumatic activation. Furthermore, hemostatic function was impaired towards hypocoagulability in either deficiency. Our results suggest that the posttraumatic activation of CD4+ Tregs and hemostatic function of platelets are affected by direct cell-cell-signaling via CD40L and P-selectin.
Basaltic and Solution Reference Materials for Iron, Copper and Zinc Isotope Measurements

Iron, Cu and Zn stable isotope systems are applied in constraining a variety of geochemical and environmental processes. Secondary reference materials have been developed by the Institute of Geology, Chinese Academy of Geological Sciences (CAGS), in collaboration with other participating laboratories, comprising three solutions (CAGS‐Fe, CAGS‐Cu and CAGS‐Zn) and one basalt (CAGS‐Basalt). These materials exhibit sufficient homogeneity and stability for application in Fe, Cu and Zn isotopic ratio determinations. Reference values were determined by inter‐laboratory analytical comparisons involving up to eight participating laboratories employing MC‐ICP‐MS techniques, based on the unweighted means of submitted results. Isotopic compositions are reported in per mil notation, based on reference materials IRMM‐014 for Fe, NIST SRM 976 for Cu and IRMM‐3702 for Zn. Respective reference values of CAGS‐Fe, CAGS‐Cu and CAGS‐Zn solutions are as follows: δ56Fe = 0.83 ± 0.07 and δ57Fe = 1.20 ± 0.13, δ65Cu = 0.57 ± 0.06, and δ66Zn = −0.79 ± 0.12 and δ68Zn = −1.65 ± 0.24, respectively. Those of CAGS‐Basalt are δ56Fe = 0.15 ± 0.07, δ57Fe = 0.22 ± 0.10, δ65Cu = 0.12 ± 0.08, δ66Zn = 0.17 ± 0.13, and δ68Zn = 0.34 ± 0.26 (2s).
Solid-state production of laccase by Pleurotus sp. applied in glyphosate degradation

 Abstract — N-phosphonomethyl glycine (glyphosate) is the derivative of the amino acid glycine. Glyphosate is a broad-spectrum herbicide. Glyphosate is translocated via phloem system and moves from the roots to the growing parts of the plants. Many researches proved that lignin-modifying enzymes LME including laccases have ability to degrade glyphosate. Pleurotus sp. was cultured during 12 days in the media with coir dust, sesame residue, urea, saccharose, K 2 HPO 4 and minerals. After 12 days, the media contain laccase with the activity of 0.227U/g. Moreover, Pleurotus sp. also grew in the media which contain glyphosate and made a decrease in this content from 50mg/kg to 10.5mg/kg after 12
Influence of temperature on occlusion body production in a Mexican isolate of Spodoptera exigua multiple nucleopolyhedrovirus

ABSTRACT In vivo production of baculoviruses requires optimisation studies for each host-virus system. Considering the potential of a Mexican isolate of Spodoptera exigua multiple nucleopolyhedrovirus (SeSIN6) for developing a biopesticide, here, a compartmentalised tray system and a cool-textured diet were used to determine the effect of incubation temperature on the pathogenicity, speed of kill, and production of occlusion bodies (OBs). All measurements were compared with a characterised American nucleopolyhedrovirus isolate (SeUS2). Incubation of fourth instar S. exigua at 20, 25, and 30°C did not significantly affect the mortality caused by either isolate, although a delay in virus infection was observed at 20°C. The OB production of both isolates in infected larvae was significantly lower at 20°C than at 25 and 30°C. At all temperatures, the OB production of the SeSIN6 isolate was higher than the SeUS2 isolate. The production of OBs per mg larva was significantly higher at 30°C for both isolates. A positive correlation was observed between larval weight gain and the production of OBs/larva at all temperatures, whereas a negative correlation was observed between larval gain weight and OBs/mg of larval weight in most of the treatments. We conclude that incubation temperatures of 25 and 30°C are optimal for OB production per larva in both isolates tested. Further studies are needed to examine other factors that can improve the production of Mexican SeMNPV isolates.
COMPUTATIONAL IDENTIFICATION OF MICRORNAS FROM SSDNA VIRUSES

MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression and the fact that they are associated with various disease phenotypes is one of the main reasons for their importance. The complexity of experimental detection of miRNAs due to their characteristics led to the development of computational methods. In this work, a machine learning based approach was applied to identify and analyze potential miRNAs that might be originated from 60 single strand DNA (ssDNA) viruses’ genomes. The results suggest that 53 of these viruses may possibly produce proper miRNA precursors. Moreover, the possibility of these candidate miRNA precursors’ ability to generate mature miRNAs that could target human genes and viral genomes has been tested. Overall, the outcomes of this research indicate that there might be another level of host-virus interaction through miRNAs which requires further experimental confirmation.
