Phase Transitions of the Ising Model

Comes from statistical mechanics, and was originally applied in 1924 to study ferromagnets. Let Λ ⊆ Z. Let σi ∈ {−1, 1} denote the ”spin” at vertex i ∈ Λ. Define a probability measure μΛ on the space of configurations Σ ≡ {−1, 1}Λ with density proportional to exp (β∑i,j∈ηΛ σiσj) where ηΛ is the set of all pairs of neighboring vertices in Λ. Setting β = 0 yields the i.i. d measure while setting β > 0 tries to get neighboring spins aligned in the same direction.
Dermatofibrosarcoma protruberans of the breast skin simulating mammary carcinoma: A case report

Dermatofibrosarcoma protuberans (DFSP) is an uncommon slow growing neoplasm of the dermis with tendency to invade the subcutaneous tissues. Usually, it behaves as an intermediate grade malignancy but in rare instances, it can metastasize. It presents in the middle age of life and frequent occurrences have been observed in trunk and extremities but involvement of the breast has rarely been reported. Pre-operative diagnosis with mammography, ultrasonography and fine-needle aspiration cytology is challenging. Histomorphology and immunohistochemistry are helpful in making a definitive diagnosis. We report a case of a DFSP of the left breast in a middle aged lady. The diagnosis was posed by histological and immunohistochemistry studies of a biopsy of the breast skin lesion (colored plaque); Tumor cells show strong reactivity for CD34 antibody. The patient is programmed for a wide local excision.
Kenaf Fiber Composites: A Review on Synthetic and Biodegradable Polymer Matrix

This review paper deals with the previous and current works published on the kenaf fiber composites. Kenaf is grown commercially in South East Asia country and widely used in the construction and infrastructure as well as in the automotive industry. Kenaf fiber is usually reinforced with synthetic based polymer resin such as polypropylene. However, recent studies tend to concern towards the environmental issues which kenaf fiber act as an alternative natural fiber competitor. Moreover, the combination of the natural fiber and the biodegradable polymer able to reduce the negative impact on human health. Hence, researcher-initiated the interest focusing on the biodegradable materials obtained from the renewable sources. A huge attention gave to the kenaf fiber reinforced bio-polymer materials such as polylactic acid. The processing technique and the fiber orientation within the composite materials are discussed extensively in order to obtain the maximum composite performance. Results indicated that the mechanical properties; tensile strength and tensile modulus, are improved as the kenaf fiber was aligned in uni-direction. Therefore, this paper overview on the kenaf retting types in the common form of kenaf fibers and discussing the thermoplastic polymer matrices types used in the fabrication processes. In addition, the challenging of using kenaf fibers composites and its application in the automotive industry also highlighted.
Association of IL8 and IL10 gene allelic variants with ischemic stroke risk and prognosis

Aim. Evaluating a role of IL8 gene –781 C/T, and IL10 gene –592C/A polymorphisms as genetic markers of ischemic stroke risk. Methods. A case group consisted of 183 patients with ischemic stroke, which were treated in the Brain Vascular Pathology unit of SI «Institute of Gerontology of NAMS of Ukraine». A control group included 88 healthy individuals older than 65 years without any history of ischemic stroke. Genotyping was performed using PCR followed by restriction fragment length polymorphism analysis. Results. Significantly (P < 0,05) higher frequency of IL8 –781T allele carriers in the case group (81,6 %) comparing to the control (70,1%) was revealed. –781T allele carriers have nearly 2-fold increased ischemic stroke develop- ment risk (OR = 1.886; 95 % CI: 1.041–3.417). Significantly (P < 0,05) higher frequency of IL10 gene –592C allele carriers was observed in the patients with ischemic stroke (98,2%) comparing to the control (90,7 %). The ischemic stroke development risk in such individuals is 5-fold increased (OR = 5.71; 95 % CI: 1.48–22.11). It was revealed that –592C allele homozygotes with ischemic stroke have more than 2-fold higher improvement (according to the Rankin scale) chances during the firstfortnight of treatment (OR = 2,76; 95 %CI: 1,26–6,07). Conclusions. Onthebasisoftheobtainedsignificantdifferences, IL8gene–781TandIL10gene–592Cvariants may be considered the factors of ischemic stroke hereditary susceptibility. Besides, IL10 gene –592CC genotype is a genetic marker of the patients state positive dynamics during first two weeks of treatment.
The Influence of Social Media Use on Knowledge Creation by Small and Medium Sized Enterprise Owners in the Culinary Sector in Jakarta

Small and medium sized enterprises (SMEs) have an important role in driving the economic growth of Indonesia. With the existence of the SME sector, unemployment is reduced. In this era of globalisation, technology continues to grow rapidly, including the presence of social media. Social media is a new form of Information and Communication Technology (ICT) that is used to create active content by employees. Employees can use social media as effectively as possible to generate benefits for businesses by using knowledge creation methods that consist of four dimensions: socialisation, externalisation, combination and internalisation. Of various business sectors, food and beverage businesses will never die, so this research uses the culinary sector. This research was conducted to analyse the influence of social media use in socialisation, externalisation, combination and internalisation by small and medium sized businesses (SMEs) in the culinary sector In Jakarta. The technique used was purposive sampling and the hypothesis test involved simple regression analysis. Methods of data collection involved questionnaires distributed to small and medium sized enterprise owner’s (SME owners) in the culinary sector in Jakarta with 194 respondents.
Review of Digital Image Watermarking Techniques

-Digital watermarking techniques have been developed to protect the copyright of multimedia objects such as text, audio, video, etc. So, we have proposed a hybrid Image watermarking technique which takes the advantages of different transforms like DWT, DCT, SVD and Arnold Transform, which enhances more security and provides robustness to the watermark. In this paper method, image is divided into several groups of frames, and one of the frames is selected where watermark will be embedded. Before embedding watermark in a selected frame it will be pre-processed with Arnold Transform which will provide security to it. The selected plane of Image are decomposed using DWT and high frequency band HH, middle frequency bands LH, HL are transformed with DCT. The DCT coefficients are SVD transformed which are embedded with corresponding transformed coefficients of watermarks along with Arnold Transform. The embedded watermark is extracted with inverse process of embedding. The proposed algorithm is tested with various Image sequences using MATLAB 2017a. The distortion quality of original image and watermark is controlled by the Peak Signal to Noise Ratio, Signal to Noise Ratio and Mean square error of the watermarked frame with original frame.
The Identity of Phyllurus milii Bory de Saint Vincent, 1823 (Squamata: Pygopodidae: Diplodactylinae)

The original illustration and descriptions of Phyllurus milii Bory de Saint Vincent, 1823 are most likely to be based on Nephrurus levis occidentalis Storr, 1963, not the species to which the name milii has been consistently applied for nearly 180 years. In the absence of types, a neotype (WAM R34085) is designated, representing the species to which the name milii has been applied by all subsequent authors, both for this species and Gekko dorrensis Peran, 1807. The senior name is identified as a nomen oblitum, and the junior name a nomen protectum, stabilising nomenclature of this species. The Thick-tailed or Barking Gecko, Nephurus milii (Bory de Saint-Vincent, 1823) is a widespread, large and readily identifiable species of southern Australia. Although the generic name has been subject to some debate, the species having been variously assigned to the genera or subgenera Phyllurus (e.g., Bory de Saint-Vincent, 1823, 1825; Gray, 1845/ 1867; Underwood, 1954; Russell, 1980), Anomalurus (Fitzinger, 1843), Gymnodactylus (e.g., Dumeril and Bibron, 1836; Boulenger, 1885; Zietz, 1920)/ Underwoodisaurus (e.g., Wermuth, 1965; Cogger, 1975; Cogger et al., 1983) or most recently, Nephrurus (e.g., Bauer, 1990; Bauer and Henle, 1994; Kluge, 1991/ 1993), the species name has been consistently applied since 1823, although variously misspelt on occasion as nihi, miliusii, myliusii, milhus or milusii (see Bauer and Henle, 1994). Since 1934 (Loveridge, 1934), the specific epithet has mostly been correctly spelt. The species was named for Lieutenant­ commander (later Baron) Pierre-Bemard Milius of Bordeaux, second-in-eommand of the corvette Naturaliste, one of two original ships of the French Baudin Expedition of 1800-1804 to Australian waters, with Bory de Saint-Vincent himself, also of Bordeaux, being one of two zoologists on the same ship (Comell, 1974). Bory de Saint-Vincent (1825, 1828) credited Milius with the discovery of the species, and for providing the colour plate drawn from life which accompanies the description. There is no evidence that Milius visited Australia, and more specifically the type locality (see below), other than with the Baudin Expedition. Bory de Saint-Vincent's description of this species was published in a popular encyclopedia of natural history several years after the premature death of Francois Peron (zoologist on the other ship of the
On Prime number varieties and their applications

Prime numbers and their variations are extremely useful in applied research areas such as cryptography, feedback and control in engineering. In this paper we discuss about prime numbers, perfect numbers, even perfect and odd perfect numbers, amicable numbers, semiprimes, mersenne prime numbers, triangular numbers, distribution of primes, relation between π and prime numbers. In the process we also obtain interesting properties of some of them and raise a set of open problems for further exploration.
Innovation diagnosis in technology companies of a regional innovation system

Goal: This article aims to diagnose the profile, strategies, and innovation practices adopted by the information technology companies of a Regional Innovation Systems (RIS). Design/ Methodology/ Approach: This study was carried out with 19 small and medium companies from a RIS in the state of Paraná, where we collect data relating to the infrastructure and investments in R&D, types of innovation projects, impact on revenue, activities of innovation, innovation protection methods, and information sources used by companies. Results: The results showed that: companies with higher investments in R&D, which generate innovative products and patents, have a higher financial return; the generation of patents is incipient among the companies surveyed; product process and organizational innovation are the main innovation activities carried out; there is some difficulty in establishing external partnerships for the development of innovation, especially with universities; customers, users, and the internet are the primary sources of information used by companies. Limitation of the investigation: With respect to research limitations, we point out that our research sample is limited to 19 companies. Thus, for the results to be generalized, a larger sample is recommended. Practical implications: The article showed that the launch of innovative products on the market has positive effects on the financial performance of companies due to increased sales. Originality / Value: This paper offers a contribution to contextual studies of innovation in RIS. In addition, it presents an innovation profile of the technology companies of an RIS. These results can be used to compare and evaluate the innovation evolution in technology companies with other sectors and other RIS, or provide an indicator for the development of innovation policies for a region.
On the Probability of the Number of Solutions for the Perspective n Point Problem

This paper studies the multi-solution phenomenon for the perspective n point problem. We obtain the probabilities for the P3P problem to have one to four solutions. We prove that with probability one, the PnP (n ≥ 4) problem has a unique solution which can be represented by a set of rational functions in the parameters. To solve the P4P problem with the rational functions is stable and accurate.
Towards Effective Curriculum Delivery: Examining the Intervening Role of Religion on Students’ Involvement in Sports Betting Among Public Secondary Schools

Habitual sports betting among students is concomitant with numerous psychological, social and health effects whose ramifications may encumber effective curriculum delivery. To this, religion, being the spiritual and moral compass of society should not turn a blind eye. Little research has however, been done to examine the role of religious intervention on mitigating gambling involvement among students. This study investigated the intervening role of religious doctrine and religious commitment on sports betting among secondary school students in Mumias-East sub-county, Kenya. It involved 369 students, obtained by stratified random sampling. Questionnaires were used for data collection. Results were analysed using frequencies and percentages, while hypotheses were tested using Chi Square. The study found that the doctrine of most religious denominations reprehended sports betting. However, there was no significant relationship between religious doctrine and involvement in sports betting. But the study found a significant relationship between students’ commitment to religion and involvement in betting. Students who were ‘Very Committed’ to religion had the least propensity for sports betting. It was thus concluded that religious doctrine per se does not affect an individual’s decision to bet or otherwise. Rather, the level of commitment to the doctrine and practice of one’s faith is what affects their decisions. The study thus recommends that schools should work with religious leaders to institute programs that enhance students’ commitment to their religious faith. It also recommends an inclusion of betting awareness in school curriculum, which could be done by integration of the content into already existing subjects.

Predicting Risk-Taking behaviour from Life-History Theory Using Static Optimization Technique

Gilliam improved the possibility of predicting habitat choice and risk-taking behaviour in juvenile animals by the rule of «minimization of mortality rate over growth rate (μ/g)», derived by using dynamic optimization technique. I have derived a similar expression (M/k) by using static optimization. M is instantaneous mortality rate, and k is the growth constant from the von Bertalanffy growth function. Both Gilliam's and my expressions were derived for situations where animals maximize fitness in stable populations (per capita growth rate r=0). The more general expression from my analysis becomes (M+r)/k. Independent of the level of maximum fitness, the slope of the M-k curve at optimum growth and mortality conditions was found to be constant. This slope was determined by fecundity, size at reproduction, and maximum attainable size (.)
New potential targets for antifungal development

With the increasing number of immunocompromised hosts and advances in medical technology there has been a concomitant rise in the number of cases of invasive fungal infections. Novel approaches for the discovery of new antifungal targets and their inhibitors will be needed. In this review we discuss how such approaches are being developed through the identification of novel biochemical and molecular targets to meet the challenges imposed by the scientific research in medical mycology.
The dimension stone sector: new perspectives on the global market and on the reporting of international mining standards

Dimension Stone, as also described in the new draft PERC Standard, is a technical/commercial term that includes all natural stones that can be quarried in blocks of different dimensions, are processed by cutting or splitting, and that possess specific technical and aesthetic properties that drive their demand in the building and construction industries. Dimension stones are distinct, in both mining methods and their end uses, from all other materials derived from natural rock, such as aggregates and granulates, cement materials, crushed stone, or industrial minerals. While aggregates, cement raw materials and crushed stones are almost exclusively used in load-bearing, filling and structural functions in building and construction, and industrial minerals are utilised for multiple purposes in many industries (ceramics, glass, pharmaceuticals, paper, etc.), Dimension Stone materials offer special qualitative features which mean they can perform both structural and decorative architectural functions in building and construction as well as in internal decoration and landscaping projects. Commercially, dimension stones are generally divided into three categories for business transactions: marbles, granites and stones.
A New Framework for Weather Detection using Image Cues

At present, weather identification from outdoor image is an emerging experimental area and a lot of researchers are working on it to treasure trove information for discovering new ideas. Even though human eyes are the prime way to identify weather condition, more artificial methods are introduced nowadays for making the machine learning techniques efficient in recognizing weather situations. The main target of this framework is to point out the correct weather condition by extracting features from each outdoor input image. Each exterior image used as input is effectively processed and categorized into one of the six weather group: sunny, rainy, haze, cloudy and thunder on the basis of Inception v3 model. This model also ensure to follow the procedures in a manner to avoid difficulties faced by various existing techniques which uses high-cost sensors, which have computational troubles and some other methods with less classification accuracy. The output is verified and compared with that of other similar methods; from where the efficiency of this model is clearly understood.
Evolutionary optimality of delayed breeding in voles

The observation that the presence of predators influence breeding rates in microtines (Yldnen 1989, Heikkila et al. 1993, Norrdahl and Korpimaki 1995) is one among the various explanations suggested to account for the cyclic dynamics shown by many vole populations (Korpimaki et al. 1991, Ylbnen 1994). According to the hypothesis, a female vole may enhance her total reproductive value by postponing breeding if the current predator density is high. Together with direct effects of predation, this results in a crash in the vole population. The main argument is that the value of a litter in the increase phase of the microtine cycle is so high that the total reproductive success of a female is increased, if she has suppressed breeding during the decrease phase (Yldnen 1994). This, in turn, is due to enhanced survival of the non-breeding female during the risky phase (Lima and Dill 1990, Magnhagen 1991). While the argumentation comprising the hypothesis seems plausible, models staying at a verbal and qualitative level may lead to erroneous conclusions due to lacking ability to compare strengths of selective pressures acting in opposite directions. According to Yldnen (1994: 429), "the value of the litter raised during this [increase] phase of the microtine cycle certainly is higher, which means a strong selective advantage for the females able to breed after the population crash". In this note we show that the "certain and strong" selective advantage proves to be far from a matter of course, when the model is studied quantitatively that is, by identifying the essential parameters to be measured in the field, and by specifying their relationships and contributions towards reproductive optimality. Lambin et al. (1995), recognising the very same problem, call for a clear identification of statements and assumptions comprising the hypothesis. They require a quantification of "the subtle trade-off between current and future reproduction and survival, whether or not they are mediated by predators" (p. 204). While it is probably true that the current empirical data do not suffice to judge the value of the hypothesis conclusively, the request can be met by theoretical considerations of the delayed breeding hypothesis as well. In this note we shall make an attempt to formalise the delayed breeding hypothesis with the introduction of time-dependent survival and reproduction parameters (Fig. 1). Our aim is to translate the hypothesis into a model of evolutionary optimality. At time t1, a young female born at to has the choice of breeding or delaying. The next possibility to breed is at time t2. The total reproductive success is measured at time step t3, so that mature offspring from both litters account for the fitness. Note that the delays between time steps need not be equal in length. For example, winter may be located between t1 and t2
Stoned

The stoned proteins, stoned A (STNA) and stoned B (STNB), are essential for normal vesicle trafficking in Drosophila melanogaster neurons, and deletion of the stoned locus is lethal. Although there is a growing body of research aimed at defining the roles of these proteins, particularly for STNB where homologues have now been identified in all multicellular species, their functions and mechanisms of action are not yet established. The two proteins are structurally unrelated, consistent with two distinct cellular functions. The evidence suggests a critical requirement for stoned proteins in recycling/regulation or specification of a competent synaptic vesicle pool. As stoned proteins may be specific to a particular pathway of endocytosis, studies of their function are likely to be valuable in distinguishing between the different mechanisms of membrane retrieval and their respective contributions to synaptic vesicle recycling, a subject of considerable scientific debate. In this review, we examine the published literature on stoned and comment on the available data, conclusions from these analyses and how they may relate to alternative models of vesicle cycling.
VOS: the Corpus-Based Vietnamese Text-to-Speech System

: This paper presents a complete specification of the Vietnamese speech synthesis system named VOS (Voice of Southern Vietnam). Due to the fact that current Vietnamese text-to-speech systems lack the naturalness of output synthetic speech, VOS is based on the unit selection approach which aims to achieve maximum naturalness. There are three main parts constituting VOS: a corpus manager, a synthesizer, and a transliteration model. Corpus manager manages automated speech indexing and segmentation for unit selection executed by the synthesizer, while transliteration model deals with the pronunciation of words in foreign languages. A comparative experimental evaluation of VnSpeech, VietVoice, and VOS is conducted using ITU-T P.85 standard. Results show that VOS outperforms the former two TTS systems.
