Correlation Between Engine and Aircraft Loadings for Several Mission Types

Fighter aircraft constitutes a well-defined class of aircraft. Their extensive use on a daily basis by operators stands as a strong motive behind studies that concern their rate of “exhaustion ”. For an aircraft operator either civil or military, it is very important at any point in time to have a clear view of the engines’ and the aircrafts’ operating condition. This is valuable information in order to foresee undesired incidences and in order to schedule missions in accordance to the actual and anticipated maintenance needs. For the latter, the operator would also need to know the rate of the engine and the aircraft life consumption per mission. The current study concerns the F-16 Block 52M aircraft, powered by the Pratt and Whitney F100-PW-229 engine. Aircraft is continuously subjected to crack growth mechanisms while flying. On the other hand, engines also go through Low Cycle Fatigue (LCF) cycles and creep prominent conditions while being in operation. The engine and the aircraft structural condition are continuously monitored, based on real time data recordings. To the extent of the authors’ knowledge, that is a common practice for most F-16 users. However, what was found to be missing from the international literature was a study to quantify any potential correlation between the aircraft loading and the engine loading for all typical mission types an aircraft of this type undertakes. For users that have already installed an aircraft loading monitoring system like “Aircraft Structural Integrity Program” (ASIP) it would be very useful to set a “rule of thumb” aside regarding the degree of correlation between aircraft and engine loading. Engine life consumption rate was estimated based on the creep and LCF failure mechanisms applied on the most critical engine section, the turbine. Engine recordings were picked from an arbitrary sample of 200 flights of a certain aircraft, wherein most typical mission types could be found. Turbine and subsequently blade temperature as well as blade stress were calculated using a very narrow time step. These data along with blade material data were fed in the Larson Miller model, to set an algorithm for estimating life consumption due to creep. Engine Total Accumulated Cycles (TACs) which account for LCF loading, are directly measured by the engine recorder, based on an embedded algorithm. Aircraft loading is calculated based on the accelerations the aircraft structures encounter during flight. These are also recorded under a very narrow time step. Last step was the correlation of the engine life consumption against the aircrafts’ loading for typical mission types. Scatter diagrams and statistical measures were used, in order to define the degree of correlation between them.
Sodium Current Measurements in HEK293 Cells

[Abstract] This protocol is used to measure sodium currents from heterologously transfected cells lines, such as HEK293 cells. Standard whole cell patch clamp technique is used to assess ion channel function. This protocol has been used to study cardiac type Na v 1.5 sodium channel, and in particular to compare wild-type and mutant channels related to Brugada Syndrome (BrS). Mutations related to BrS provoke a loss of function of the cardiac sodium channel. This is evidenced by a reduction of sodium current density and/or alterations of the activation or inactivation kinetic parameters, such as a slow recovery from inactivation. These effects could explain the alteration of the cardiac action potential that leads to the characteristic ST elevation observed in the electrocardiogram of the Brugada Syndrome patients. This protocol, with some variations, is suitable for studying other cardiac arrhythmias related to alterations in the cardiac type sodium channel function as well as for studying other voltage-dependent sodium channels.
Analisis Framing Pemberitaan Kebijakan Pemerintah Terkait Ketenagakerjaan sebagai Dampak Covid 19 di Kompas.com dan Malaysiakini

Abstract In the beginning of 2020 the mass media coverage was adorned with information about covid-19 outbreaks. The spread of covid-19 has crossed continents and even the rest of the world, making this period called as pandemic because it has infected 4.9 million people. The magnitude of this incident made the media including Kompas.com and Malaysiakini.com continue to convey information not only about health issues, but also other impacts in various fields such as law, politics, security and other social issues such as the economy and employment. This online news portal from Indonesia and Malaysia always reports on the development of covid-19 outbreaks in their respective countries. So much news was uploaded by the two online media that researcher only chose one news related to labor policy as the impact of covid-19 outbreaks. Using the theory of reality construction from Peter L. Berger, researcher analyzed the news framing using Robert N Enmant's model. The results showed an imbalance between the two online news portals because it only represented one party, where Kompas.com fetched news about wages from the point of view of the business world while Malaysiakini framed the appeal for the suspension of Eid Al-fitr leave that delivered by Mufti P Pinang as an opinion leader who respected by the Malaysian society. Keywords: Framing Analysis, Policy, Labor, Pandemic, Online Media.
10. Local Brokerage Positions and Access to Unique Information

: The theory of structural holes (Burt 1995) provides an explanation regarding network positions and their associated benefits in many social settings. One of the key points of the theory is formulated on the node level and is about efficient access to information and resources. Namely, actors bridging structural holes by connecting otherwise disconnected segments of a social network, the brokers, have access to information that circulates over the network while simultaneously maintaining relatively small number of ties. For example, scientists often maintain non-redundant collaboration ties because they are associated with academically-relevant resources unavailable in other collaborations. Apart from the above node-level property one can formulate a tie-level property corresponding to the ‘ tie redundancy ’ . Studying a process of the network information diffusion explicitely with a computational experiment and tools of information theory allows us to compare local properties of the diffusion with structural features related to the Burtian notions of brokerage and redundancy. We argue and demonstrate that (1) the above mentioned node-level and tie-level properties can be supplemented with a triad-level one. Specifically, that the notion of ‘ tie redundancy ’ should be in fact considered as an essentially triadic property. Further, (2) each of the three properties is associated with a viable empirical strategy of testing whether (aspects of) the structural holes mechanism is at work in a given network.
Changes of preferential flow path on different altitudinal zones in the Three Gorges Reservoir Area, China

Liu, M. , Du, W. and Zhang, H. 2014. Changes of preferential flow path on different altitudinal zones in the Three Gorges Reservoir Area, China. Can. J. Soil Sci. 94: 177-188. Preferential flow in soil macropores plays an important role in runoff control and soil and water conservation. The aim of this study was to investigate the distribution of preferential flow paths in the soil profile of various altitudinal belts, analyze its variation among different soil horizons, and define the cause of soil macropores. A dye tracer method combined with photographic analysis was conducted for four hillslope sites in the Three Gorges Reservoir Area of China (TGRA). The results show that stained area proportion, as well as its vertical distribution in soil sections, presented varied patterns due to changes of forest vegetation and soil type with altitude. Stained area ratio of soil profiles increased, while stained depth decreased with increasing altitude. For soil sections in the subalpine belt, mid-mountain belt, and low-mountain belt of TGRA, stained area ratios were 62, 42, and 45%, and stained depths were 52.4, 56.4, and 69.5 cm, respectively. For brown earth covered with subalpine temperate deciduous broad-leaved forest, stained area ratios were the largest, but dyed patches were concentrated in the humus horizon. For yellow earth covered with low-mountain warm coniferous forest, stained depth reached 69.5 cm, and stained patches existed in the total soil profile. Compared with forest soil, stained depth and stained area ratio of abandoned farmland in low-mountain belt were lower, and the depth of dye infiltration was even shallower.
Effects of post-annealing temperature and oxygen concentration during sputtering on the structural and optical properties of β-Ga2O3 films

In this study, β-Ga2O3 thin films were directly deposited on sapphire substrates by radio-frequency magnetron sputtering. The effects of post-annealing temperature and oxygen concentration during sputtering on the structural and optical properties of the films were investigated in detail. The results indicated that the crystalline quality of the films improved with increasing post-annealing temperature. When 1 vol. % oxygen was included in the deposition process, β-Ga2O3 film displayed the best crystalline quality, the band gap and atomic ratios of O to Ga of the film were increased, and the content of oxygen vacancies in the film was effectively lowered. These results revealed an effective, convenient method to prepare high-quality β-Ga2O3 thin films.

NOVEL APPROACH OF PHARMACEUTICAL CO-CRYSTALS FOR POORLY SOLUBLE DRUGS

Curcumin a polyphenolic active pharmaceutical ingredient, extracted from curcuma longa possess a wide variety of pharmacological activities. The utility of curcumin is limited by its, lack of water solubility, and relatively low invivo bioavailability. In this context, Co-crystal approach are non-ionic supramolecular complexes and can be used to address physical property issues such as solubility, stability and bioavailability in pharmaceutical development without changing the chemical composition of the API. Novel co-crystal of curcumin with methyl paraben was obtained by liquid assisted grinding method by (1:1) molar ratio. This formulation was evaluated for Anti-inflammatory activity. FT-IR, DSC, PXRD results delineation of the hierarchy of hydrogen bonding between complementary functional groups or supramolecular heterosynthons can be accomplished. The percentage of inhibition in paw edema after 3 h were recorded 67.71 % in case of Indomethacin, 55.73% in case of 100 mg/kg of Curcumin, 66.67 % in case of 100 mg/kg of Curcumin co-crystals respectively.
Analysis of Total Terpenoids from Maniltoa Grandiflora (A. Gray) Scheff Leaves Using TLC and HPLC Methods

Terpenoids screening were carried out using Liebermann Burchard and Salkowski reagent on the extract of Saputangan leaves. It showed that the leaves contained terpenoid compounds with appeared of a reddish brown ring in the extract and a reddish brown stain appeared on the TLC plate tested with 1% CeSO4 reagent in 10% H2SO4. The macerate of saputangan leaves processed separation using the partition method (Liquid-liquid Extraction). Extracts dissolved with methanol were partitioned with n-Hexane and then partitioned between aquadest and ethyl acetate in a ratio of 1: 1 to obtain 50 g of total terpenoids. Furthermore, TLC analysis was performed on total terpenoids using n-hexane: ethyl acetate (80:20 v/v) solvent to obtain 11 separate stains on the TLC plate with different Rf each. Analysis was enhanced in HPLC using 100% acetonitrile and 0.1% phosphoric acid at a wavelength of 210 nm, a flow rate of 0.500 mL/min and eluted for 30 minutes. Based on the HPLC results, there were 25 peaks which indicated the presence of total terpenoid compounds with the highest peak being peak no. 8 (ret.time's 6.234, area's 8503532 and height's 276032), peak no. 9 (ret.time's 6.674, area's 3322572 and height's 141859) and peak no. 10 (ret.time's 7.288, area's 2758231 and height's 103927).
The Suitability of Students in Bachelor of Science in Statistics (BSS) Program

This study aims to assess the suitability of students in Bachelor of Science in Statistics program. Seemingly, several students who enrolled in the said program does not possess the qualities of being mathematically inclined. Hence, this study was conducted. By complete enumeration, the study employed all BSS students from different year level. Secondary data were used such as two psychological tests from the University Student Services Office which measures the intelligence and numerical aptitude. A primary data was also employed through an instrument called Brainard Occupational Preference Inventory which measures the interest of students in the field of statistics. The gathered data were then analyzed with the aid of some descriptive measures and correlational methods. Results revealed that there are only a few (11.9%) who have high levels of intelligence and numerical aptitude but they happen to have low level of interest in statistics. Of those students highly interested (47.6%) in the field of statistics one-fourth (11.9%) of them have low levels of intelligence and numerical aptitude. It is found out that there is a significant linear relationship between intelligence and numerical aptitude among BSS students. Moreover, intelligence and interest in statistics is inversely and significantly correlated among BSS junior students. Furthermore, results showed that there is no significant linear relationship between numerical aptitude and interest in statistics across year level. Hence, the interest of the BSS students must be cultivated in order to increase their level of achievement.
Bar quenching: Evidence from star-formation-rate indicators

The central regions of star-forming barred spiral galaxies can be devoid of star formation because of the redistribution of gas along the length of the bar. However, there can be gas outside the length of the bar that can host star formation. We study a sample of barred disc galaxies in the local Universe with an aim to discriminate between centrally quenched and globally quenched galaxies based on their positions on star-formation-rate–stellar mass (SFR−M⋆) plots and to find a connection between the SFR of quenched galaxies and the length of their bar. We classified barred galaxies as centrally quenched and globally quenched based on their position on SFR−M⋆ plots, with SFRs derived from Hα flux and spectral energy distribution fits on combined ultraviolet and optical flux. We selected galaxies as passive based on the distance from the main sequence relation. From a total 2514 barred galaxies studied here, we present 651 with suppressed star formation in their central region but hosting star formation outside. We also find a possible correlation between bar length and SFR for the galaxies that are fully quenched because of the stellar bar.

Dual-Attention Residual Network for Automatic Diagnosis of COVID-19

The ongoing global pandemic of Coronavirus Disease 2019 (COVID-19) has posed a serious threat to public health and the economy. Rapid and accurate diagnosis of COVID-19 is crucial to prevent the further spread of the disease and reduce its mortality. Chest computed tomography (CT) is an eﬀective tool for the early diagnosis of lung diseases including pneumonia. However, detecting COVID-19 from CT is demanding and prone to human errors as some early-stage patients may have negative ﬁndings on images. In this study, we propose a novel residual network to automatically identify COVID-19 from other common pneumonia and normal people using CT images. Speciﬁcally, we employ the modiﬁed 3D ResNet18 as the backbone network, which is equipped with both channel-wise attention (CA) and depth-wise attention (DA) modules to further improve the diagnostic performance. Experimental results on the large open-source dataset show that our method can differentiate COVID-19 from the other two classes with 94.7% accuracy, 93.73% sensitivity, 98.28% speciﬁcity, 95.26% F1-score, and an area under the receiver operating characteristic curve (AUC) of 0.99, outper-forming baseline methods. These results demonstrate that the proposed method could potentially assist the clinicians in performing a quick diagnosis to ﬁght COVID-19.
Automatic Evaluation of the Mechanical Properties of Steels Maraging using Digital Image Processing Techniques

Some strategic sectors of the economy require that the raw material of their machines and equipment have mechanical properties that satisfy their use. Maraging steel is a material of great concern since it is necessary to have a high mechanical resistance associated with high fracture toughness. The traditional tests to determine the fracture toughness of this material before use in applications are the Charpy and KIC tests. However, this process is characterized by being exhaustive and requiring specialized and trained professionals. Thus, to reverse this situation, this work proposes a new approach to determine the mechanical properties of maraging steel. For this, initially, the method removes any artifacts present in the image resulting from the mode of acquisition. In sequence, this works tested the method Extended Minimum Transformation (EMT) and mathematical morphology to find these markers of the regions of the dimples. Then, the Adaptive Thresholding, Optimal Global Thresholdusing the Otsu Method and Watershed transformation methods were used to segment the dimples. In the end, the diameter of the dimples and the toughness of the material were calculated. Tests are carried out and compared with the result obtained by specialists using the traditional system to evaluate the proposed approach. The results obtained were satisfactory for the application because the proposed approach presented speed and precision to the conventional methods.
Asymmetric Cost Behaviour and Earnings Quality in the European Context

This study investigates the relationship of asymmetric cost behaviour with earnings quality for European listed firms. We employ a sample that consists of 11,416 firm-year observations of European listed firms over the period 2005-2019 to explore the relationship of asymmetric cost behaviour with (i) the managerial incentives to meet earnings targets, (ii) conditional conservatism, (iii) the level of operating accruals, and (iv) earnings smoothing. Our empirical evidence indicates that the presence of managerial incentives to meet earnings targets decreases the intensity of SG&A cost stickiness. We also document that asymmetric timeliness estimates in the conditional conservatism estimation models have an upward bias unless these models do not control for asymmetric cost behaviour. Finally, it seems that the levels of operating accruals and earnings smoothing are more sensitive to sales decreases than sales increases.
Hybrid Device-to-Device and Device-to-Vehicle Networks for Energy-Efficient Emergency Communications

Recovering postdisaster communications has been a challenging task for search and rescue. Recently, device-to-device (D2D) and device-to-vehicle (D2V) networks have drawn attention. Nonetheless, the limited D2D coverage and onboard energy pose a new need for establishing a hybrid D2D and D2V network. In this article, we jointly establish, optimize, and integrate D2D and D2V networks to support energy-efficient emergency communications. First, we establish a D2D network by optimally dividing ground devices (GDs) into separated clusters and identifying temporary data caching centers (TDCCs) from GDs in clusters. Accordingly, emergency data returned from GDs are cached in TDCCs. Second, given the distribution of TDCCs, unmanned aerial vehicles (UAVs) are dispatched to fetch data from TDCCs. Therefore, we establish a UAV-assisted D2V network through path planning and network configuration optimization. Specifically, optimal path planning is implemented using cascaded waypoint and motion planning, and optimal network configurations are determined by multiobjective optimization. Consequently, the best tradeoff between emergency response time and energy consumption is achieved, subject to a given set of constraints on signal-to-interference-plus-noise ratios, the number of UAVs, transmit power, and energy. Simulation results show that our proposed approach outperforms benchmark schemes in terms of energy efficiency, contributing to large-scale postdisaster emergency response.
