Multispectral Phase-Based Geosteering Coherence Attributes for Deep Stratigraphic Feature Characterization

The deep exploration has become the focus of attention in the field of earth sciences. Coherence is a routine measure to identify structural and stratigraphic anomalies, such as faults, channels, and fractures in subsurface. However, deep seismic data typically suffer from a low signal-to-noise ratio and a weak reflection amplitude, thus it may not provide a better insight for seismic attribute analysis. The phase information has the ability to detect subtle changes in subsurface but it is sensitive to noise, thereby masking some stratigraphic features in the full-bandwidth data. To address these two issues, we propose a multispectral phase-based geosteering coherence method by combining coherence and spectral decomposition for deep stratigraphic feature characterization. The proposed method can effectively select and utilize the phase components of favorable spectral bands, which can detect different scale geologic discontinuities and reduce or avoid the effect of random noise in deep seismic data. Furthermore, corendering the coherence images of three different frequency components using red–green–blue blending can detect more geologic details in subsurface. The examples including 3-D physical modeling data and real seismic data set of carbonate reservoir from western deep formation are employed to demonstrate the effectiveness of the proposed method. The coherence attributes obtained from the proposed method can detect the weak or hidden geologic details clearer than the geosteering coherence calculated from the broadband seismic data, and it may serve as a future tool for detecting the distribution of geologic abnormalities in deep exploration.
Non-linear Mixed Models in a Dose Response Modelling

Desain studi dimana hasil diukur berulang kali dari waktu ke waktu menghasilkan data longitudinal. Sebagian besar metodologi yang digunakan untuk menganalisis data longitudinal adalah model linear dan model linear umum ( generalized linear model ) dimana sejumlah linearitas tertentu dipertahankan. Asumsi linearitas ini masih dipandang memiliki keterbatasan dan model non-linear adalah pilihan metode lainnya yang menawarkan fleksibilitas. Model non-linear telah digunakan di berbagai macam situasi seperti model kurva pertumbuhan, model farmakokinetika, dan farmakodinamika, dan model respon-dosis. Model respondosis akan menjadi fokus dalam penelitian ini untuk membangun hubungan respondosis sebagai fungsi waktu dari data IBD dengan menggunakan model linear dan non-linear. Hasil penelitian menunjukan bahwa model non-linear lebih fleksibel daripada model linear sehingga mampu menangkap lebih banyak variabilitas yang ada di dalam data.
Influence of neutron and gamma irradiation on the electrocaloric properties of Mn-doped 0.9Pb(Mg1/3Nb2/3)O3–0.1PbTiO3 ceramics

The influence of neutron and gamma irradiation on the low- and high-field dielectric and electrocaloric (EC) properties of Mn-doped 0.9Pb(Mg1/3Nb2/3)O3–0.1PbTiO3 (PMN–10PT) ceramic is studied. Upon exposure to neutron fluences of up to 1017 cm−2 and gamma-ray doses of up to 1200 kGy the Mn-doped PMN–10PT exhibits a lower saturated polarization, increased internal bias field and reduced EC temperature change. In comparison, the respective properties of the undoped PMN–10PT remain almost unchanged upon exposure to neutrons and gamma rays. In Mn-doped PMN–10PT, the acceptor-oxygen vacancy defect complexes, introduced via doping, contribute to the lowering of the threshold radiation dose that the material survives without noticeable changes in properties. Radiation-induced degradation of the EC response of Mn-doped PMN–10PT can be partially healed by annealing at 450 °C. The study provides guidance for designing EC ceramic materials for solid-state cooling applications in environments of high ionizing radiation, such as the medical field or space technologies.
Organisational learning: Some considerations for human resource practitioners

In a business environment of rapid change, many organisations seek to embrace organisational learning strategies to harness the abilities of all members. This paper addresses some of the pitfalls organisations confront in implementing learning strategies, and discusses practical issues and strategies HR practitioners need to take into account. The importance of empowered and involved employees is commonly recognised, but not so the need to have boundaries, which shape a culture of learning and encourage experimentation, while protecting the individual and organisation from undue risk. Leadership behaviour, communication and rewards also need to be congruent if organisations want to foster a culture of sharing knowledge and experimentation that is sustainable.
Bar Formation, Gas Evolution, and Star Formation in Barred-Spiral Galaxies

Bar structures are common in spiral galaxies. The understanding of the evolution of the bar galaxy is essential to the overall understanding of the disk galaxies. Many previous studies have done research on the evolution of bar galaxies, but there are still many parts that are not well understood, such as the temporal and spatial distributions of star formation in a nuclear ring, the formation and evolution of gaseous structures especially the ring size, and the effects of the gaseous component on a stellar bar. In this thesis, using both hydrodynamic simulations and self-consistent simulations including star formation and feedback, we try to understand unsolved problems for barred spiral galaxies. We first investigate the star formation in a nuclear ring without spiral arms. We use hydrodynamic simulations to study temporal and spatial behavior of star formation occurring in nuclear rings of barred galaxies where radial gas inflows are triggered solely by a bar potential. The star formation recipes include a density threshold, an efficiency, conversion of gas to star particles, and delayed momentum feedback via supernova explosions. We find that star formation rate (SFR) in a nuclear ring is roughly equal to the mass inflow rate to the ring, while it has a weak dependence on the total gas mass in the ring. The SFR typically exhibits a strong primary burst followed by weak secondary bursts before declining to very small values. The primary burst is associated with the rapid gas infall to the ring due to the bar growth, while the secondary bursts are caused by re-infall of the ejected gas from the primary burst. While star formation in observed rings persists episodically over a few Gyr, the duration of active star formation in our models lasts for only about a half of the bar growth time, suggesting that the bar potential alone is unlikely responsible for gas supply to the rings. When the SFR is low, most star formation occurs at the contact points between the ring and the dust lanes, leading to an azimuthal age gradient of young star clusters. When the SFR is large, on the other hand, star formation is randomly distributed over the whole circumference of the ring, resulting in no apparent azimuthal age gradient. Since the ring shrinks in size
Comparison of Neuromuscular Joint Facilitation and Quadriceps Strengthening Exercise in Knee Osteoarthritis: a Randomized Controlled Trial

Objectives To compare the effect of neuromuscular joint facilitation (NJF) and quadriceps strengthening exercises on pain, physical function, static posture, and balance control in subjects with knee osteoarthritis. Design Randomized controlled trial. Setting Department of Physiotherapy, Manipal Hospitals, Bangalore. Participants Subjects diagnosed with knee osteoarthritis according to the American College of Sports Medicine criteria. The mean age of subjects in the control group was 63.12 ± 8.08 years; in the experimental group was 61.77 ± 8.46 years. Interventions The intervention group received NJF treatment twice a week for six weeks, and the control group received quadriceps strengthening exercises. Standard knee exercises were given as a home program to both groups. Outcome Measures Numeric Pain Rating Scale (NPRS), 30-second chair stand (30s-CST), and single leg stance (SLS) were used to assess physical function, static posture, and balance control, respectively, at the end of the sixth week. Results Sixty subjects were randomly allocated to intervention and control groups. The experimental and control group showed a mean difference of 3.89 and 4.17 in NPRS, 4.19 and 4.17 in 30s-CST, 6.81 and 5.71 in SLS at the end of six weeks. This change was significant within both groups (p value .000) and not significant between groups (NPRS p value .303; 30s-CST p value .09; SLS p value .525) at the end of six weeks. Conclusions NJF and quadriceps strengthening exercises effectively reduced pain and improved physical function, static posture, and balance control in subjects with knee osteoarthritis. Both groups had the same effect on all clinical variables at six weeks of follow-up. Hence, further studies with long term follow-up are warranted.
Existence and Iteration of Monotone Positive Solution for a Fourth-Order Nonlinear Boundary Value Problem

This paper is concerned with the following fourth-order three-point boundary value problem BVP \[ u^{\left(4\right)}\left(t\right)=f\left(t,u\left(t\right)\right),\quad t\in\left[0,1\right], \] \[ u'\left(0\right)=u''\left(0\right)=u\left(1\right)=0,\;u'''\left(\eta\right)+\alpha u\left(0\right)=0, \] where $f\in C\left(\left[0,1\right]\times\left[0,+\infty\right),\left[0,+\infty\right)\right)$ , $\alpha\in\left[0,6\right)$ and $\eta\in\left[\frac{2}{3},1\right)$. Although corresponding Green\textquoteright s function is sign-changing, we still obtain the existence of monotone positive solution under some suitable conditions on $f$ by applying iterative method. An example is also given to illustrate the main results.
Convergent Dynamics In Physiological Response As A Window-Based Robust Control System

The process adapted here delivers physiological readings and maps out the major components that make up the physiological system. The contribution of this component can also be determined on each of the parameters. The skin conductance response (SCR) has a major effect on the synchronous readings of the physiological metrics used. The paper investigates this default by developing a prototypical representation of integrated physiological readings with real-time analytics using a convergent dynamic control model as the inference engine. The major components that make up the physiological system and errors, are characterised by either their noisiness or systematic disturbance. The noisy error is based on the obvious pattern in each time interval and it is measured based on the mean root square error(MRSE). The SCR has a major effect on the synchronous readings of the physiological metrics used. The results obtained from test runs indicate that the Tonic phase of the physiological response signal is the skin conductance level (SCL) that represents the base level of the signal. The Phasic level is the component of the skin conductance response that reflects the direct response to the external stimulus, and this is set between 1-4secs after the stimulus onset at the baseline phase. There also exists the non-specific SCR known as the anomalies that appear post-stimuli; this represents the number of conductance responses that appear within and among subsequent physiological response readings. The originality of work is its ability to visualise multi-modal response signals in a single frame and detect optimal responses significant to a particular event-related protocol
ANTIOXIDANT AND ANTI-SICKLING ACTIVITY OF EXTRACTS FROM THE STEM AND ROOTS BARKS OF STRYCHNOS INNOCUA (DEL.)

Objective: In Togo Strychnos innocua represents a plant traditionally used to cure sickle cell disease. This study aims to carry out a phytochemical study and evaluate the antioxidant and anti-sickling activity of Strychnos innocua root and stem barks to support its use. Methods: Hydroethanolic and ethanolic extracts of each plant organ were obtained by maceration. Polyphenol content was determined using the Folin-Ciocalteu’s reagent and the flavonoid content using Aluminium trichloride (AlCl3) method. The anti-sickling activity of hydroethanolic extracts of root and stem barks was tested on SS blood samples from sickle cell patients using the Emmel test. Antioxidant activity was assessed by DPPH and FRAP methods on both the hydroethanolic and ethanolic extracts. Results: Results indicate that the highest levels of polyphenols were measured in the hydroethanolic extract of the root barks (59.32±1.77 mg GAE/g) and the ethanol extract of the stem barks (98.27±2.44 mg GAE/g). The hydroethanolic extract of the root barks and the ethanolic extract of the stem barks showed high levels of flavonoids. Extracts from both organs significantly reduced falciformation (p<0.001) at a rate of 22% (root) and 35% (stem) compared with the control (94%). In addition, root and stem extracts showed slight antioxidant activity. Conclusion: Results justify the traditional use of Strychnos innocua roots in treating sickle cell anaemia.
Structural, mechanical, electronic, thermal, and optical properties of the inverse-Heusler compounds X2RuPb(X = La, Sc): A first-principles investigation

Topological insulators are novel quantum material states with insulating bulk band gaps and topologically protected metallic surface states that have been extensively studied owing to their intriguing properties for spintronic and quantum-computing applications. The structural, mechanical, electronic, thermal, and optical properties of inverse Heusler compounds La2RuPb and, Sc2 RuPb in two Hg2CuTi, Cu2 MnAltype structures were calculated using the full potential linear muffin-tin orbital simulation methodology as implemented in the computer code,which is based on density functional theory.We employed the local-density approximation for the exchange and correlation potential (XC) terms. Consequently, the optical characteristics of La2 RuPb, Sc2 RuPb and elastic constants Cij and their corresponding elastic moduli were computed for the first time. According to our structural calculations, La2 RuPb is more stable in its Hg2 CuTi-type structure than Sc2 RuPb in its Cu2 MnAl-type structure. However, the mechanical characteristics demonstrate their stability in the final stages of elastic deformation.
Reparative Calcified Barrier Characterization after Mixing Injectable-Platelet Rich Fibrin with Bioactive Direct Pulp Capping Agents; An Exp. Study

Aim: This study investigated the morphology and localization of hard tissue barriers formed after direct pulp capping using i-PRF mixed with bioactive agents (Mineral Trioxide Aggregate (MTA) and Bioactive Bone Graft (BBG)) in dogs' teeth using Scanning Electron Microscope. Materials and methods: A total of 64 teeth were used out of 8 healthy male mongrel dogs. The teeth were randomly assigned into four groups according to capping agents used, they were exposed and capped as follow, Group A; capped with MTA, Group B; capped with MTA+ i-PRF, Group C; capped with BBG, Group D; capped with BBG + i-PRF. Finally the access cavity was restored with Intermediate Restorative Material (IRM). The dogs were euthanized after 1 month; and samples were then prepared for scanning electron microscopic study. SEM was used to assess the morphology, localization and extension of the reparative hard tissue barriers and using an image-processing and analysis software to delimit the perimeters of the root canal area and the hard tissue barrier to determine the percentage of root canal obliteration. Chi-square test was used for intragroup comparisons. Results showed that all groups were statistically different (P < 0.05), regarding tissue barrier morphology.
The effect of row direction on the microwave emission from vegetation canopies

Experiments were conducted to determine the microwave brighthness temperature of corn and soybean canopies as a function of polarization and azimuth look direction. A strong dependence on row direction and polarization is observed for soybeans. The corn canopy shows a similar dependence, although to a lesser extent. The variation in brightness temperature is shown to be related to the canopy alone, since the underlying soil surface was blocked by reflecting metal screens.
Metamorphic Malware and Obfuscation: A Survey of Techniques, Variants, and Generation Kits

The competing landscape between malware authors and security analysts is an ever-changing battlefield over who can innovate over the other. While security analysts are constantly updating their signatures of known malware, malware variants are changing their signature each time they infect a new host, leading to an endless game of cat and mouse. This survey looks at providing a thorough review of obfuscation and metamorphic techniques commonly used by malware authors. The main topics covered in this work are (1) to provide an overview of string-scanning techniques used by antivirus vendors and to explore the impact malware has had from a security and monetary perspective; (2) to provide an overview of the methods of obfuscation during disassembly, as well as methods of concealment using a combination of encryption and compression; (3) to provide a comprehensive list of the datasets we have available to us in malware research, including tools to obfuscate malware samples, and to finally (4) discuss the various ways Windows APIs are categorized and vectorized to identify malicious binaries, especially in the context of identifying obfuscated malware variants. This survey provides security practitioners a better understanding of the nature and makeup of the obfuscation employed by malware. It also provides a review of what are the main barriers to reverse-engineering malware for the purposes of uncovering their complexity and purpose.
Scaffold and Cell-Based Tissue Engineering Approaches as Alternative Therapy for Blood Vessel Disease

Cardiovascular diseases remain the leading cause of mortality worldwide. Although new therapies are actively being developed and used for cardiovascular pathologies, these attempts have not significantly decreased mortality rates. Regenerative medicine has made enormous progress and set promising approaches over the past half-century. However, since autologous (donor-derived) vascular grafts are lacking, an alternative prosthesis must be constructed for cardiovascular disease patients. In vascular tissue manufacturing and regenerative medicine, scientists seek to improve this significant clinical challenge using bio-fabrication techniques combining additive manufacturing, biomaterials science
The knowns and unknowns of cardiac autoimmunity in viral myocarditis

Myocarditis can result from various infectious and non‐infectious causes that can lead to dilated cardiomyopathy (DCM) and heart failure. Among the infectious causes, viruses are commonly suspected. But the challenge is our inability to demonstrate infectious viral particles during clinical presentations, partly because by that point, the viruses would have damaged the tissues and be cleared by the immune system. Therefore, viral signatures such as viral nucleic acids and virus‐reactive antibodies may be the only readouts pointing to viruses as potential primary triggers of DCM. Thus, it becomes hard to explain persistent inflammatory infiltrates that might occur in individuals affected with chronic myocarditis/DCM manifesting myocardial dysfunctions. In these circumstances, autoimmunity is suspected, and antibodies to various autoantigens have been demonstrated, suggesting that immune therapies to suppress the autoimmune responses may be necessary. From this perspective, we endeavoured to determine whether or not the known viral causes are associated with development of autoimmune responses to cardiac antigens that include both cardiotropic and non‐cardiotropic viruses. If so, what their nature and significance are in developing chronic myocarditis resulting from viruses as primary triggers.

So that later it can facilitate the development of application features based on the needs of the users of the Truku logistics application.
Hand Index: An Anthropo-Forensic Tool for Human Identification in India

The aim of the study was to determine and classify the hand index of 200 individuals selected randomly within age group 18 – 65 years from Udaipur district, Rajasthan, India. The measured parameters are hand length and hand breadth. This study also attempt to compare the hand index obtained from direct as well as indirect (from hand print & hand outline) methods. Data were analyzed using SPSS Statistical software. Results shows that there were statistically significant differences in the hand parameters of male compared to female subjects for all observed parameters. It is interesting that hand index obtained from different methods doesn’t indicate variation however there exist statistically significant variation in terms of hand length and hand breadth. Also there is statistically significant difference between the hand dimensions obtained from different methods. Hand classification denoted that population of Rajasthan state belongs to dolichocheir (dch) group of hand for all the direct and indirect methods. The comparison of hand index with populations of 17 different states of India indicates that Indian population belongs to any category of hand index except hyperbrachycheir. Also an attempt has been made to observe the correlative effect of climate divisions of India with the hand categories. Comparison with 25 other foreign countries shows the existence of hyperbrachycheir that is broader large palm but short fingers. This shows that morphological characteristics of hand depend on many factors such as gender, ethnicity, socio-cultural domain, environment & genetic factors and it differs from region to region. Thus, it can be said that Identification of hand parameters is very helpful in concealing identity of mutilated remains in any disastrous act, also in examination of chance evidences in crime scene for criminal proceedings and this comparative data of hand index can also help to determine the resident place of an unknown individual.
