House Price Prediction with An Improved Stack Approach

As a typical framework in ensemble learning, Stacking creates a multi-layer learner by integrating the learning results of different individual learners. Despite a general improvement in accuracy, multiple layers in stacking results in high computation cost. In addition, some individual learners do not perform better than others in single-model prediction task. To solve the above drawbacks of traditional stacking, this paper proposes an improved Stacking algorithm based on the concept of “weighted attribute”. For each individual learner, a corresponding weight will be calculated based on its prediction performance on training data. Weights will then be used as evaluation criteria for model performance. Models with larger weights will be selected as attributes for meta-learner. When improved Stacking algorithm is applied on the same dataset, experiment results indicate a slight improvement in prediction accuracy and a relatively large reduction in computation cost. This demonstrates practical application value of the improvement.
Facile assembly of a S@carbon nanotubes/polyaniline/graphene composite for lithium–sulfur batteries

A carbon nanotube/polyaniline/graphene (MWCNT–PANI–G) composite as sulfur host has been prepared by a simple self-assembly approach with potential application for lithium–sulfur (Li–S) batteries. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) were used to investigate the microstructures and morphology of the as-prepared samples. It is demonstrated that the sulfur can be evenly impregnated into the MWCNT–PANI–G composite with strong chemical bonding. The resultant S@MWCNT–PANI–G composite with a sulfur content of 68 wt% shows excellent electrochemical performance as cathode for Li–S batteries. It delivers a high initial discharge capacity up to 1290 mA h g−1, good capacity retention of 784 mA h g−1 after 100 cycles of charge/discharge at the current density of 330 mA g−1, and good rate capability of 663 mA h g−1 and 548 mA h g−1 at 1.65 and 3.3 A g−1, respectively. The remarkable electrochemical performances are mainly attributed to the unique architecture of MWCNT–PANI–G with an enhanced electronic and ionic conductivity. Furthermore, this special architecture can provide strong physical and chemical confinement to the active materials and the soluble lithium polysulphides. Therefore, our study demonstrates a facile and low-cost approach to fabricate cathode materials for high-performance Li–S batteries.
TRANSLATIONAL SCIENCE IN CHRONIC TENDINOPATHIES

Introduction Chronic tendinopathies involves majority of patients in clinical practice of orthopaedic surgeons and sports physicians. The burdens of these problems to a society adversely effect the social, economical,occupational, recreational and physical aspect of patients. Translational medicine confers an emerging medical advances efficiently towards the clinician directly from scientists which may used as a targeted therapy. Objectives: The main objective of translational research from “bench to bedside” is to test novel inventions in humans. Our purpose in this article to understand the translational medicine approach for chronic tendinopathies in clinical aspects. This fulfill the basic objectives of translational science to promote further medical and surgical care with ease. Methods We conducted search in electronic database of google scholar, pubmed ,Embase, web of science, Elsevier and science direct with reviews till October 2020. After obtaining search we narrowed our search for articles in terms of getting a literature specifically mentioned about translational medicine ,translational sciences, chronic tendinopathies. Methodological quality assessment and analysis were done in order to obtain relevantrepresenatation that best suited to our objectives for this article. As this is a narrative review we tried to accommodate important aspect of research and future directives for clinical implications as well as future research in the fields. Discussion: Translational research in chronic tendinopathies is required certainly due to plenty of reasons. Newer advances and targeted approach to these tendon disorders may curtail the further degenerative process. It aids in earlier diagnosis and prevention of morbidity, early occupancy of occupational activity, lack of economical as well as recreational failure. Pre-disease level activity is ultimate goal of any therapy. Current guidelines are lacking in agreement for any single guidelines for tendinopathies. Moreover, there aren’t any clearly defined ideal treatment protocol. Tendon pathophysiology is constantly evolving researched topic in both biochemical as well as molecular aspect. Clinical implications of such emerging techniques and treatments where “bench to bedside” and “bedside to bench” motto of translational medicine should be fastened in order to achieve a newer approach. Conclusions: The basic fundamental understanding of complex process of tendon healing and regeneration is necessary for formulating a newer guidelines. The cornerstone of treatment of tendinopathies is still non-operative management. Physical therapy, better pain control, NSAIDS are still primary choice for these conditions. Various biological therapy whenever used one should combined them with other appropriate options to obtain an optimum outcome.

Event‐based switching control for networked switched systems under nonperiodic DoS jamming attacks

: This study addresses the event-based control of networked switched systems subject to cyber attacks. A novel mode-based event-triggered mechanism is proposed, which is capable of characterising non-periodic denial-of-service (DoS) attacks. A switching control law is employed in each subsystem to weaken the negative effects caused by DoS attacks. The time sequences of system switchings, event triggerings and intermittent DoS attack behaviours are fully investigated, which yields a resultant closed control system. Then, by using piecewise Lyapunov functional methods, sufficient conditions are formulated to guarantee the concerned system exponentially stable. Meanwhile, the co-design methods for switching controllers and event-triggering parameters can be developed. Finally, a numerical simulation example and a practical example of a second-order oscillating circuit are presented to verify the proposed methods.

KUALITAS ORGANOLEPTIK DAGING SE’I YANG DIOLAH DARI DAGING SAPI BALI BETINA AFKIR (Organoleptic quality of se’i made from bali cull cow beef)

Aim of this study was to evaluate quality of se’i (Rotennese smoke meat) made from cull Bali cow meat. Completely randomized design 3x3 was used in this study. Meat taken from cull Bali cow with body condition skore (BCS) 2 (thin), 3 (moderate) and 4 (slightly fat). Each BCS had three replicates. Parameters observed included taste, color, aroma, pH value and fat oxidation. The results showed that BCS had a highly significant effect (P <0.01) on color and taste, had a significant effect (P <0.05) on fat oxidation, had no significant effect (P> 0.05) on aroma and pH. Se,i made from BCS 4 had a slightly dark red color, the best taste and the highest fat oxidation rate, whereas se'i prepared from BCS 3 has a slightly dark red color, medium taste and lowest fat oxidation rate. It is concluded that the best quality of se’i produced in this study was made from BCS 4,however, it was necessary to add antioxidants to retard fat oxidation rate. Whereas if used BCS 3 it is better to add some additives to improve the taste.
Structure of Lithium Niobium Nitride

Lithium niobium(V) nitride, Li7NbN4, Mr = 197.49, cubic, Pa3, a = 9.829 (1) A, V = 949.6 (4)/k 3, Z = 8, Dx = 2.77 g cm-3, Mo Ka, a = 0.71069/~,/z = 22.8 cm-~, F(000) = 720, T= 298 K, final R = 0.031 for 369 unique reflections. Li7NbN4 crystallizes as a superstructure of the anti-fluorite structure. Each octant of the cubic structure contains a distorted LiTNb cube, which is oriented so that the eight Nb atoms in the unit cell occupy successively each of the distorted cube vertices. The Li7Nb cube is further surrounded by a larger cube with N atoms at the vertices and face center positions. The Nb order- ing produces rows along (100) containing three Li atoms and one Nb atom per unit cell, and an equal number of rows containing only Li atoms. The struc- ture obtained differs from those previously proposed for cubic LivVN4 and for distorted Li7NbN4 and
Decoupling of Real and Digital Content in Projection-based Augmented Reality Systems Using Time Multiplexed Image Capture

Projection-based augmented reality systems overlay digital information directly on real objects, while at the same time use cameras to capture the scene information. A common problem with such systems is that cameras see the projected image besides the real objects to some degree. This crosstalk reduces the object detection and digital content registration abilities. The authors propose a novel time sharing-based technique that facilitates the real and digital content decoupling in real time without crosstalk. The proposed technique is based on time sequential operation between a MEMS scanner-based mobile projector and rolling shutter image sensor. A MEMS mirror-based projector scans light beam in raster pattern pixel by pixel and completes full frame projection over a refresh period, while a rolling shutter image sensor sequentially collects scene light row by row. In the proposed technique, the image sensor is synchronized with scanning MEMS mirror and precisely follows the display scanner with a half-period lag to make the displayed content completely invisible for camera. An experimental setup consisting of laser pico projector, an image sensor, and a delay and ampliﬁer circuit is developed. The performance of proposed technique is evaluated by measuring the crosstalk in captured content and sensor exposure limit. The results show 0% crosstalk in captured content up to 8 ms sensor exposure. High capture frame rate (up to 45 fps) is achieved by cyclically triggering a 3.2 MP, 60 fps CMOS sensor and using a 60 Hz pico projector.

Cattle identification: the history of nose prints approach in brief

Petersen was the first published paper to address cattle biometrics and identification problem by suggesting a permanent cattle identification method based on nose print principles widely accepted today. His major concern was on proper identification of cattle for registration and of cattle on an official test so that the possibility of swapping, false insurance claims, and ownership disputes can be guarded against. It was with this identification problem in the mind of every breeder that the practicable suggestion of using nose print as means of identification was made by O. H. Baker of the American Jersey Cattle Club in Petersen’s paper entitled “The identification of the bovine by means of nose-prints”. Before the advent of the nose print method, cattle identification has been by conventional constructs such as tattoo, tags, photographs, descriptions, branding (hot and freeze), ear notching, and sketching (drawings) the color markings on them on paper for registration and identification purposes. These classical methods of identification cause trouble among the breeders especially when their cattle are sold or are on an official test due to lack of artistic ability on the part of the breeders which makes the matching of the sketches and the markings on the cattle disagree. Presented in this paper are the various cattle biometrics and identification methods, most especially from the classical methods to the modern methods.
Mechanism of cell death : early morphological changes and DNA degradation of apoptosis in rat thymocytes

Apoptosis is an active process of gene-directed cellular self-destruction. It serves a biological meaningful and homeostatic function in diverse circumstances, including embryonic development, physiological involution or pathological atrophy of adult organs, normal tissue turnover, immune cell ontogeny and immune killing. A new flow cytometric method using Hoechst 33342/ propidium iodide staining has been established in this study. The basis of this method is the change of apoptotic thymocytes both in cell size and membrane permeability. This method has been used to study glucocorticoids or DNA topoisomerase inhibitor-induced apoptosis in immature rat thymocytes both in vitro (dexamethasone, etoposide, mAMSA and camptothecin) and in vivo (etoposide). During establishment of the flow cytometric method, it was found that induction of apoptosis by dexamethasone was not inhibited by zinc as assessed by flow cytometry. Further studies indicated that apoptotic thymocytes induced by dexamethasone in the presence of zinc showed distinct morphology and other cellular changes characteristic of apoptosis but no DNA laddering. Thus, internucleosomal cleavage of DNA was, for the first time, dissociated experimentally from early nuclear morphological changes, as well as other cytoplasmic changes. Identification of a transitional preapoptotic population of thymocytes further confirmed this observation. In this population of cells, early nuclear morphological changes and other cytoplasmic changes were observed in the absence of DNA laddering. By using field inversion gel electrophoresis, it was found that formation of kilobase pair fragments of DNA preceded internucleosomal cleavage of DNA. Formation of large fragments of DNA was particularly visualised when thymocytes were treated with dexamethasone in the presence of zinc, due to an inhibitory effect of zinc on the internucleosomal cleavage of DNA. These large fragments of DNA were also present in the transitional preapoptotic population of thymocytes in the absence of oligonucleosomal fragments. Further studies with isolated thymocyte nuclei showed that formation of these large fragments o f DNA was a Mg2+-dependent process that can be facilitated by Ca^+. The nature of these large fragments, the mechanism involved in their formation and their relevance to apoptosis reqire further investigation.
Electrochemical detection of DNA damage induced by clenbuterol at a reduced graphene oxide-Nafion modified glassy carbon electrode

An electrochemical biosensor capable of direct detection of DNA damage induced by clenbuterol (CLB) has been developed. A glassy carbon electrode (GCE) was modified using reduced graphene oxide-Nafion and dsDNA to produce a dsDNA/RGO-Nafion/GCE sensor. The modified electrode was characterized by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV), and the results at each stage of the electrode construction were interpreted. They indicated that the electrochemical oxidation peak currents of guanine and adenine at the electrode (dsDNA/RGO-Nafion/GCE) significantly increased as compared with those at the untreated electrode (dsDNA/GCE). Based on this, the sensor was used to measure the change of the oxidation peak currents for guanine and adenine between the intact and damaged dsDNA in the sensor films, and the DNA damage was successfully detected. Furthermore, the plot of peak current decline for the guanine and adenine versus the concentration of CLB was linear in the range of 5.0 × 10−7 to 4.0 × 10−6 mol L−1, with a limit of detection (LOD) of 3.2 × 10−7 mol L−1, which provided a good method to determine CLB indirectly.
Preservice Teachers’ Use of Web 2.0 Tools and Perspectives on their Use in Real Classroom Environments

New understandings and methods have proliferated as technology continues to root itself more deeply in an increasing number of areas within the field of education, causing, naturally, the technology-based tools to find a wider application in assessing students‘ knowledge and progress. With the resulting rapid development of Web applications, Web 2.0 tools have found a niche in a great many steps of the instruction process and have emerged as an integral part of educational technology. Indeed, those studying to become teachers are, quite naturally, one of the most important factors in ensuring that further improvements in this type of technology will be incorporated in mathematics instruction. Accordingly, this study aims to examine what preservice teachers thought of a class during making up part of their teacher training in which they used Web 2.0 tools (e.g., Plickers, Kahoot, Edmodo, ZipGrade) to design activities and lesson plans that they implemented in real classroom settings, which were then discussed in together as a class. The research is conducted with the case study method and the participants consisted of 24 senior preservice teachers of primary school mathematics education in a state university in Turkey. The study‘s data were collected using written interview forms and subsequently analyzed using content analysis. At the end of the study, it was found that Web 2.0 tools contribute to professional development, instruction and student-teacher-parent interaction dimensions for teachers; on the other hand, it was revealed that it contributes to affective characteristics, learning and skills dimensions in terms of students. Concerning limitations, preservice teachers stated that the need for the Internet and technological devices in order to use Web 2.0 tools were significant obstacles to their use. Based on the conclusions, it is recommended that future studies investigate the effects of different Web 2.0 tools on different content areas as part of preservice teacher training.
