TRAJECTORY OPTIMIZATION FOR A DIFFERENTIAL DRIVE SOCCER ROBOT

This paper addresses the problem of designing a strategy for a differential drive soccer robot. The objective is to develop an efficient attacker, that is capable of scoring goals in two ways: pushing the ball and “kicking” it. The robot should also avoid obstacles, i.e., the opponent’s robots and the ones from our team. Since the system is underactuated and nonlinear, we can not use a classical control approach, and trajectory optimization led to good results in this case. We also show simulation results that validate the proposed approach. Keywords— Differential Drive Robot, Trajectory Optimization, Motion Planning.
Update on nasal polyps: etiopathogenesis.

PURPOSE OF REVIEW Nasal polyps is a common ENT disease with high medical failure and recurrence rate, reflecting unknown pathogenesis. The present review is an update on the etiopathogenesis of nasal polyps. RECENT FINDING Several mechanisms have been proposed for the formation of nasal polyps, including allergy, mucosal allergy, autonomic imbalance, nitric oxide, superantigens, infection, abnormal transepithelial ion transport, mucopolysaccharide abnormality, mechanical obstruction and epithelial rupture. Eosinophils comprises more than 60% of the cell population. Activated T cells, mast cells and plasma cells are also increased compared with the normal nasal mucosa. The stroma has numerous mediators, including cytokines, growth factors, adhesion molecules, and immunoglobulins. Both Th1 and Th2 types of cytokines are upregulated independent of the atopic status. An increased production of GM-CSF, IL5, RANTES and eotaxin can contribute to chronic eosinophilic inflammation by regulating the migration, survival and activation of eosinophils. CONCLUSION Nasal polyps is a multifactorial disease, with infectious, noninfectious, inflammation, anatomic and genetic abnormalities. Chronic inflammation remains the central major factor in nasal polyps.
Improving the FIFA ranking system using probabilistic modeling and prediction of the UEFA EURO 2016 tournament

The goal of this research is to find an improved football ranking system with the FIFA (Fédération Internationale de Football Association) male ranking[1] system as the baseline reference. Predictive performance is used to assess the quality of the proposed ranking systems. Both structured settings where all teams play each other a fixed number of times and unstructured match settings are researched. Premier League data is analyzed in the structured setting and European national matches are analyzed in the unstructured setting. Three main classes of models are considered for all analyses: Bradley-Terry (BT) models that only consider the match outcomes (home win, draw or home loss), Poisson models that use the match results (e.g. 3-2 home win) and model both the number of home and away goals using a Poisson distribution, and Elo models which also use the match results. The model parameters for BT and Poisson models are estimated using maximum likelihood estimation whereas the team strength ratings are updated after each match in Elo models. Six classes of statistical methods (2 BT, 2 Poisson, one blend of BT and Poisson, one Elo) are considered to predict football matches in the predictive part of the research. Prediction of the second half of Premier League matches over a 15 season period (2000-2014) revealed that the best Poisson models outperform the best BT and Elo type models with respect to the log loss criterion. The same six classes of models are considered to predict the upcoming UEFA EURO 2016 tournament in France. The preferred model is again selected using the log loss criterion over 20 years (1986-2015) of European international matches. A simulation study using the preferred model is used in the final stage in order to come up with a detailed prediction of the expected performance of all participating teams. Simulating the tournament 100,000 times without reassessing the model after each round of matches revealed that France is the current favorite to win the tournament followed by Germany and Belgium. The ranking of the tournament participants of the simulation study aligns better with the predicted ranking by the bookmakers, which can be treated as the gold standard, than the most recent FIFA ranking. The simulation study rank has a mean absolute rank difference of 2.7 compared to the bookmaker rank while the mean absolute rank difference between the FIFA rank and the bookmaker rank is 4.5.
The Effect of Self-Esteem on Consumers ’ Attitude toward Second-Hand Luxury Products

With the development of luxury economy, second-hand luxury products have become an important part in the China’s luxury market. This paper investigates the effect of consumers’ self-esteem on their attitude toward second-hand luxury products. By conducting a research on Chinese adult consumers, we find that self-esteem has negative effect on consumers’ attitude toward second-hand luxury products, and the symbolic value of second-hand products is the mediator. Meanwhile, we find the moderating effects of AD appealing mode (appealing on price value vs. appealing on social value) of second-hand products. We have theoretical discussion and marketing suggestions for second-hand luxury products in the end.
Sounding Rocket and Balloon Activities and Related Research in Switzerland 2009-2011

There have been miscellaneous activities performed by Swiss-based research groups in relation to high altitude research during the past few years. Research platforms used involve, in addition to sounding rockets and stratospheric balloons also high altitude stations in the Swiss Alps. The research topics are spread across various disciplines of science, including physics, astrophysics, meteorology and biology/medicine. A typical example would be a balloon experiment of the University of Bern testing a new generation of neutral gas mass spectrometer designed for a Mars mission. Another balloon experiment carried out by the École Polytechnique Fédérale de Lausanne (EPFL) is designed to measure protons, helium, electrons, positrons and anti-protons in cosmic rays. In contrast, the Zero-g LifeTec Company is engaged in a biomedical study investigating the activation behavior of human immune cells under microgravity condition during a sounding rocket flight. Space Research has been made accessible not only to distinguished research-institutes but also to students of Swiss universities. A project from EPFL has been selected by ESA recently for a participation in the REXUS/BEXUS program. Switzerland offers researchers high altitude research stations which allow the investigation of the upper atmosphere without using balloons or sounding rockets. The two research facilities at Jungfraujoch and Gornergrat are frequently used by research teams from all over Europe and overseas. A very short summery of a few Swiss projects under the framework of sounding rocket and balloon activities and related research carried out between 2009 and 2011 is provided in the following paragraphs.
A Review of MP 3 Steganography Methods

Nowadays, information security is an important thing. Much confidential information such as personal data, financial data, and even state secrets of confidential data needs to be protected so that it cannot be misused by others who are not authorized to do. One step for maintaining the security of information is by using steganography technique. Steganography image is the development of science from steganography. The first part of this paper explains what steganography means in general. Then proceed with the explanation of the study of the application of steganography on MP3 (MPEG Layer3) audio. Many methods can be used in steganographic techniques on MP3 files as though Least Significant Bit (LSB), Spread Spectrum, Direct Sequence Spread Spectrum (DSSS), Parity Coding, Phase Coding, Echo Hiding, DCT and DWT. The final part of this paper will explain the future work on steganography.

Mushroom is use in the preparation of several delicacies in many part of Nigeria, There is dearths of information on the nutritional qualities of oyster mushroom (Pleurotus sajor caju) cultivated on gmelina wood waste. Hence, this study is designed to ascertain the nutritional composition and phytochemical properties of indigenous wild species of oyster mushroom (Pleurotus sajor caju) and the exotic species that is commercially grown on gmelina wood waste at the Forestry Research Institute in Ibadan, Nigeria. The samples were obtained and analysed for proximate, mineral and phytochemical properties on dry weight basis using standard methods. Results of Proximate analyses of the exotic and wild oyster mushroom samples were: moisture (7.00 and 7.15%), protein (19.30 and 25.24%), crude fat (7.24 and 6.65%), crude fibre (7.47 and 7.05%), total ash (7.13 and 8.25%) and carbohydrate by difference (51.86 and 45.66%) respectively. Qualitative analysis of both samples showed the presence of the following phytochemicals: alkaloid, saponin, tannin, cardiac glycosides and flavonoid. The quantitative analysis of the phytochemical properties of the exotic specie’s showed saponin (4.05%), flavonoid (0.06%) tannin (0.27%) cardiac glycosides (0.63%) and alkaloid (10.05%); while, the wild specie showed saponin (3.03%), flavonoid (0.09%), tannin (0.30%) cardiac glycosides (1.45%) and alkaloid (9.64%). Alkaloid seems to be the most predominant phytochemical in the two mushroom species. The values obtained for the predominant minerals content of the exotic sample were: potassium (mg/100g), magnesium (154.75mg/100g), calcium (142.79 mg/100g) and iron (116.90mg/100g); Most of the values were lower compared with the values of the wild counterpart as follow: potassium (665.89mg/100g), magnesium (162.93mg/100g), calcium (147.23mg/100g) and iron (125.61mg/100g). The other minerals for the exotic species ranged from 68.75mg/100g (manganese) to 0.22mg/100g (molybdenum) while, the wild specie ranged from 72.79mg/100g (manganese) to 0.16mg/100g (molybdenum). This study concluded that oyster mushroom grown on gmelina wood waste favourably compared with the wild counterpart and has potential for use as acceptable human food.
Forkhead Transcription Factor FoxM1 Regulates Mitotic Entry and Prevents Spindle Defects in Cerebellar Granule Neuron Precursors

ABSTRACT The forkhead transcription factor FoxM1 has been reported to regulate, variously, proliferation and/or spindle formation during the G2/M transition of the cell cycle. Here we define specific functions of FoxM1 during brain development by the investigation of FoxM1 loss-of-function mutations in the context of Sonic hedgehog (Shh)-induced neuroproliferation in cerebellar granule neuron precursors (CGNP). We show that FoxM1 is expressed in the cerebellar anlagen as well as in postnatal proliferating CGNP and that it is upregulated in response to activated Shh signaling. To determine the requirements for FoxM1 function, we used transgenic mice carrying conventional null alleles or conditionally targeted alleles in conjunction with specific Cre recombinase expression in CGNP or early neural precursors driven by Math1 or Nestin enhancers. Although the overall cerebellar morphology was grossly normal, we observed that the entry into mitosis was postponed both in vivo and in Shh-treated CGNP cultures. Cell cycle analysis and immunohistochemistry with antibodies against phosphorylated histone H3 indicated a significant delay in the G2/M transition. Consistent with this, FoxM1-deficient CGNP showed decreased levels of the cyclin B1 and Cdc25b proteins. Furthermore, the loss of FoxM1 resulted in spindle defects and centrosome amplification. These findings indicate that the functions of FoxM1 in Shh-induced neuroproliferation are restricted to the regulation of the G2/M transition in CGNP, most probably through transcriptional effects on target genes such as those coding for B-type cyclins.
A Study of Secure Deduplication Systems and Key Technologies

In the age of big data, the dramatic growth of data in enterprises poses critical challenge on storage and management. Data deduplication technique recognizes the redundancies in data streams, and just transfers and stores the unique data objects, thereby effectively reducing costs. From security perspective, this paper focuses on the advances of secure deduplication systems. We describe the deduplication architecture as well as its security requirements. Then, we introduce content-based encryption, which is the core methodology of building secure deduplication systems, and analyze the principles and limitations of the state-of-the-art technologies. Finally, we summarize existing works about secure data deduplication systems, and discuss future research directions.
Urban transformation through property-led regeneration: A case of building renewals in Istanbul

Urban transformation is a prominent topic within Istanbul’s urban planning agenda. Transformation process of the city falls under the scope of academicians and the related authorities; and is a focus of debate from different perspectives in daily life. In this atmosphere, centralised policies promote construction facilities as the leading economic sector, and the legislation sets the legal framework facilitating transformation processes. This transformation in Istanbul occurs in two forms; as area-based regeneration projects and single building renewal processes. Area-based regeneration projects have long been examined due to their widespread effects, however single building renewal also leads to transformation over the long term. The motivation behind this paper is to examine the single building renewal process by means of a case study – Bakirkoy, which is one of the sub-centres of Istanbul. In this context, the paper aims to construct an analytical evaluation of the regeneration process in Bakirkoy and tries to evaluate the process linking it with critiques of property-led regeneration debates worldwide. This paper covers a periodical evaluation of this process by attempting to understand the urban transformation pattern by means of a descriptive spatial analysis, and a discussion of recent policies in Bakirkoy case.
The projection of the visual field to the lateral geniculate and medial interlaminar nuclei in the cat

Detailed and complete projection maps of the visual field to the whole of the dorsal lateral geniculate (LGNd) and medial interlaminar nucleus (MIN) of the cat have been prepared by plotting the receptive fields of single units in the two nuclei with tungsten‐in‐glass microelectrodes. The standard projection maps show the pattern of isoazimuths (“horizontals”) and isoelevations (“verticals”) in the two nuclei. Particular attention has been given to the projection of the upper visual field to the posterior part of the LGNd/MIN complex where the shape and relationship of the cellular laminae are changing rapidly. A separate projection of the visual field to the nucleus perigeniculatus (NPG) is also described, but the retinotopic organization of this projection is not as precise as for the LGNd and the MIN. Most of the cells in the NPG are binocularly‐activated and the receptive fields have ON/OFF centers. Further observations have been made concerning the distribution of the crossed and uncrossed fibers in the LGNd. In lamina B there is a thick dorsal zone of contralaterally‐activated cells and below this is a zone in which ipsilaterally‐activated cells are occasionally found. A few binocularly‐activated cells were found in the vicinity of the interlaminar regions.
Influence Of High Water Temperature On Sex Differentiation In An Ornamental Fish

Fishes are known abundant vertebrates on earth that exhibit a large variety of mechanisms of sexual determination. Sexual determination was referred to the event that compromises a bipotential gonad to develop as an ovary or a testicle (Hayes et al., 1998). The processes of sexual determination and differentiation in fish is a complex process and a labile mechanism, under the control of both genetic factors and certain environmental factors (Baroiller et al., 1999; Munday et al., 2006; White et al., 2006; and Sandra et al., 2010). The mechanism that determines whether the bipotential gonad will differentiate as a testes or an ovary is one of the most plastic processes in the evolutionary developmental biology of fishes. (Herpin and Schartl, 2008). Many teleostean species do not present morphologically differentiated sex chromosomes and hence sexing is difficult and alternative techniques to those based on karyotyping are commonly used for the determination of sex. But since DNA structure is not anticipated to change with altered physiology or environments. (Felip et al., 2005; Bardakci, et al., 2000; and Kovacs et al., 2001). RAPDs, RFLPs, AFLPs are considered as sex-specific DNA sequences. Several environmental factors are known to trigger the process of gonad differentiation leading to altered sex ratio in wild as well as farmed fish (Siegfried, 2010). Further temperature is the predominant of all that examined to date Abstract: Identification of sex in lower animals is a difficult task, since genetic and ecological factors are also involved in sex determination. Deciding the sex of a developing embryo has a paramount importance in genetic studies, which is a sensitive process. Therefore, sexspecific genetic markers can be developed using advanced molecular techniques such as RAPDs, AFLPs. Sex determination and differentiation in fish is a complex trait. But as fish are ectothermic in nature, it is known that water temperature can modify the sex determination. In this context the present study is aimed to observe the effect of short term exposure of 20/25/30 days post hatching (dph) juveniles of Zebra fish, Danio rerio (albino) exposed to high temperatures (32 ± 0.5°C/36 ± 0.5°C) on phenotypic sex with reference to genetic sex. 72 hrs exposure to elevated water temperature was found to exhibit phenotypic sex ratio of ♂:♀ of 68:22/56:44 (in 20/25dph respectively) at 32 ± 0.5°C and 98:2.0/ 72:28 (in 20/25dph respectively) at 36 ± 0.5°C compared to 50:50 ratio in control group maintained at 28 0.5° C or those exposed to higher temperatures at 30dph.
BEAM INSTABILITIES AFTER INJECTION TO THE LHC

Long-lasting phase oscillations have been observed at injection into the LHC since its first start-up with beam. These oscillations, however, were not leading to noticeable losses or blow-up in operation, and were therefore not studied in detail. In 2017, dedicated measurements with high-intensity bunches revealed that oscillations can lead to losses even slightly below the baseline intensity for the high-luminosity upgrade of the LHC. For the first time, high-resolution bunch profile acquisitions were triggered directly at injection and the formation of large-amplitude non-rigid dipole oscillations was observed on a turn-by-turn basis. First simulations can reproduce this instability via bunch filamentation that takes place after injection, depending on the mismatch between the bunch and bucket size in momentum at injection.
PREDICTING THE NUMBER OF CYCLES OF GROUND MOTION

The seismic response of any system with degrading characteristics is dependent not only on the maximum amplitude of the motion but also its duration. This is explicitly recognised in methods for estimating the liquefaction potential of soil deposits and in the HAZUS methodology for assessing potential losses in the building stock due to earthquake shaking. Many researchers have proposed that the number of effective cycles of the ground motion are better than measures of duration for determining the destructiveness of the shaking. In liquefaction studies, it is generally the number of cycles of motion that is considered. However, as is the case with strong-motion duration, there is no universally accepted approach to determining the effective number of cycles of motion, and the different methods that have been proposed can give widely varying results for a particular accelerogram.
Anti anaemic properties of Scoparia dulcis in Trypanosoma brucei infected rabbits

A major feature of infection with trypanosomes is the development of anaemia. In this study, the effect of Scoparia dulcis (Atiotiousha in Akoko-Edo) on Trypanosoma brucei induced anaemia was investigated in fifteen rabbits divided into three groups of n = 5 over a period of twenty eight days. Changes in Packed cell volume (PCV), Haemoglobin (Hb) concentration, Red blood cell count (RBC), Mean cell haemoglobin (MCH), Mean cell haemoglobin concentration, (MCHC) and Mean cell volume (MCV) were monitored over the period. The results obtained indicate that infection with T. brucei results in a significant decrease (p<0.05) in PCV, Hb concentration and RBC. No significant (p>0.05) changes were observed in MCH, MCHC and MCV. However the severity of observed anaemia was significantly less pronounced (p<0.05) in the infected rabbits that were treated with S. dulcis when compared with their infected but untreated counterparts. It is concluded that S. dulcis therapy may prove useful in the management of T. brucei anaemia, and possibly other forms of anaemia, although the precise mechanism by which the preparation enhances the haematological indices investigated remains to be fully understood.
Remaining Useful Life Prediction of Lithium-Ion Batteries Based on Spherical Cubature Particle Filter

Lithium-ion batteries are critical components to provide power sources for commercial products. To ensure a high reliability of lithium-ion batteries, prognostic actions for lithium-ion batteries should be prepared. In this paper, a prognostic method is proposed to predict the remaining useful life (RUL) of lithium-ion batteries. A state-space model for the lithium-ion battery capacity is first constructed to assess capacity degradation. Then, a spherical cubature particle filter (SCPF) is introduced to solve the state-space model. The major idea of the SCPF is to adapt a spherical cubature integration-based Kalman filter to provide an importance function of a standard particle filter (PF). Once the state-space model is determined, the extrapolations of the state-space model to a specified failure threshold are performed to infer the RUL of the lithium-ion batteries. Degradation data of 26 lithium-ion battery capacities were analyzed to validate the effectiveness of the proposed prognostic method. The analytical results show that the proposed prognostic method is more effective in the prediction of RUL of lithium-ion batteries, compared with an existing PF-based prognostic method.
On the Fairly Reasons for Single-Issue Terrorism in Developed Countries

This paper is dedicated to discuss about the supposed ethical reasons for Single-Issue Terrorisms on developed Countries, handling as example the antiabortion group Army of God. The goal is to debate the idea of legitimacy of terrorism and criticise the myth which says that terrorist violent behaviour is proper of non-democratic states with no stability or development.
