Dermoscopic Features Summarization and Comparison of Four Types of Cutaneous Vascular Anomalies

Objective: Dermoscopic features of cutaneous vascular anomalies have been reported, but the described features currently known are limited and not well-understood. The aim of this study is to comprehensively summarize and compare the dermoscopic features of the four different types of cutaneous vascular anomalies [infantile hemangiomas (IH), cherry angioma (CA), angiokeratomas (AK), and pyogenic granuloma (PG)] in the Chinese Han population.Materials and Methods: Dermoscopic features of 31 IH, 172 CA, 31 AK, and 45 PG were collected based on the contact non-polarized mode of dermoscopy at 20-fold magnification. Dermoscopic features including background, lacunae, vessel morphology and distribution were collected and summarized. Additionally, we compared these features by age stage, gender, and anatomical locations in CA.Results: The dermoscopic features of IH included the red lacunae, red/red-blue/red-white backgrounds, and vessel morphology such as linear curved vessels, serpiginous vessels, coiled vessels. For CA, the lacunae appeared reddish brown to reddish blue or only red. In terms of vascular morphology, serpentine vessels, coiled vessels, looped vessels, and curved vessels could be seen in the lesions. A few lesions were black or presented with a superficial white veil. There were statistical differences in red background (P = 0.021), unspecific vessel distribution (P = 0.030), black area (P = 0.029), and white surface (P = 0.042) among different age groups. Red-brown lacunae (P = 0.039), red-blue (P = 0.013), red-white background (P = 0.015), black area (P = 0.016), and white surface (P = 0.046) were of statistical difference in terms of the locations of lesions. Lacunae were also observed in AK, which presented with red, dark purple, dark blue, black. Global dermoscopic patterns that were characterized by a homogeneous area were obvious in all PG lesions, among which 30 (66.7%) were red-white and 15 (33.3%) were red. As for local features, “white rail” lines were detected in 19 (42.2%) lesions and white collarette was seen in 34 (75.6%) lesions.Conclusions: Dermoscopy is an applicable diagnostic tool for the diagnosis of cutaneous vascular anomalies. It is necessary to take into account the age stage and lesion location when we diagnose CA using dermoscopy.

FAKTOR PENENTU NILAI HARTA TANAH PERUMAHAN TERES SATU TINGKAT DI BANDAR BARU SAMARIANG, KUCHING, SARAWAK

Penilaian harta tanah yang dibuat adalah bertujuan untuk jualbeli, sewa, percukaian, dan sebagainya. Harta tanah merangkumi empat sektor, salah satu daripadanya adalah sektor kediaman. Rumah merupakan keperluan asas manusia dan menjadi petunjuk utama dalam menilai kualiti hidup penduduk. Walau bagaimanapun, memiliki rumah pada masa kini bukanlah suatu yang mudah disebabkan peningkatan harganya. Walaupun peningkatan harga rumah berlaku hampir di setiap negeri, akan tetapi faktor-faktor yang boleh mempengaruhi nilai kediaman tersebut adalah berlainan. Terdapat pelbagai faktor yang menjadi penentu ke atas nilai harta tanah. Oleh itu, kajian ini dilakukan bertujuan untuk membangunkan model faktor penentu nilai harta tanah perumahan teres satu tingkat di Bandar Baru Samariang melalui kaedah statistik ruangan. Penyelidikan ini diperincikan kepada tiga objektif iaitu, mengenalpasti faktor-faktor penentu nilai harta tanah, membangunkan model faktor penentu nilai harta tanah menggunakan kaedah statistik ruangan dan menentukan kekuatan pengaruh faktor terhadap nilai harta tanah berdasarkan model yang dipilih. Penilaian ini memberikan tumpuan kepada responden yang tinggal di perumahan yang terletak di Bandar Baru Samariang termasuklah Taman Putri, Samariang Aman dan Bandar Baru Samariang. Seramai 49 orang responden dipilih berdasarkan lokasi rumah (tepi, tengah dan hujung) menggunakan persampelan rawak berlapis. Hasil kajian mendapati terdapat tujuh faktor penentu nilai harta tanah di Bandar Baru Samariang. Model yang dibangunkan adalah OLS dan GWR, didapati model GWR adalah lebih baik. Hasil daripada analisis statistik ruangan terdapat tiga faktor signifikan, antaranya ialah black area, kedudukan lot rumah dan jalan raya utama. Ketiga-tiga faktor tersebut banyak memberikan kekuatan pengaruh faktor nilai harta tanah di Taman Putri. The valuation of real estate is for sale, rent, taxation, and so on. Real estate comprises four sectors, one of which is the residential sector. Home is a basic human need and is a key indicator of the quality of life of the people. However, owning a home today is not an easy task given the high price. Although home prices increase almost every state, the factors that may affect the value of a home are different. There are many factors that determine the value of a property. Therefore, this study aimed to develop a factor model for determining the value of single-storey terraced housing in New Samariang Town through the statistical method. The research is focused on three objectives namely, identifying factors determining property values, developing a model of property valuation factors using spatial statistics method and determining the influence of factors on property values ​​based on the selected model. This assessment focuses on the respondents living in housing located in the new town of Samariang including the Princess Park, Samariang Aman and the new town of Samariang. A total of 49 respondents were selected based on home location (edge, middle and end) using random sampling. The results show that there are seven factors determining the value of real estate in Bandar Baru Samariang. The models developed are OLS and GWR, it is found that the GWR model is better. As a result of the statistical analysis of the room there are three significant factors, including black area, home lot position and main road. These three factors greatly influence the value of property values ​​in Princess Park.

A Scientific Study of the Unidentified Flying Objects in accordance with Anti-Gravity

<p>Electrohydrodynamics, semi-quantum kinetics, anti-gravity, electro-gravitics, gravito-electrics, all these are classified as the ‘black’ area of theoretical and experimental physics because, these theories tend to explain the amazing science behind the alien means of propulsion, thereby giving answers to many questions like, how they travel such long distances? Do they need any kind of fuel? If so, then why are they not seen to be massive like the rockets with 80-90% fuel capacities? Do they travel in perpetual motion? Is the fact really true that they can harness energy from the nature? Then, do they travel at a speed faster than that of light? These, along with many facts are still unexplainable to modern day physics, its not unexplainable but rather its covert and classified, government does not want to disclose the science behind UFOs that they have gathered through reverse engineering of ‘crashed alien crafts’ and through the covert research of many scientists who were engaged in black R&D operations. This paper will answer the researches and physics behind those unexplained phenomena’s because, once explained they tend to shake the pillars of modern physics.</p>

Also discussed are the requirements for measuring statistically representative areas of the sheet; the difference between the dirt physical size and Equivalent Black Area (EBA) size; and the implication of these issues when specifying cleanliness acceptance criteria. This technical brief describes on-machine visible dirt measurement’s relationship to standard laboratory testing.

A Model to Improve the Implementation Standards of Street Lighting Based on Solar Energy: A Case Study

This paper aims to improve the implementation standards of solar-energy-based street lighting in Indonesia. A model framework was developed to assess existing conditions regarding the level of lux, the distance between poles, pole height, and lamp power. According to the evaluation of the existing circumstances, the street lighting system is not satisfactory according to the national standard, with 64.7% black area. An alternative installation of street lighting designed by DIALux application was proposed to fulfill the technical standard of street lighting. The result shows that this alternative design can be used for renewing existing street lighting with better performance and reliability. Economic analysis of all technically feasible alternatives was conducted afterward by benefit–cost analysis. The analysis shows that solar-energy-based street lighting requires as much as 621,473,620.00 Indonesian Rupiah (IDR), with 1.06 benefit–cost ratios and a 9% reduction of total cost. Therefore, the analysis indicates that solar-energy-based technology can be feasibly implemented in a street lighting system. The results show that the proposed model can be applied to improve the implementation standard of solar-energy-based street lighting.

Effect of Preparation Process on Surface Quality and Microstructure of Titanium Sheet

At present, domestic cold-rolled titanium sheets have many surface defects, which are significantly different from foreign surface quality. This paper mainly studies the differences in the microstructure and performance of titanium plates GR1 and GR2 imported from Japan and domestic titanium plates TA1, and analyzes the causes of surface defects to solve the problem about TA1. The surface properties of different materials were observed. The mechanical properties of the materials were obtained by room temperature tensile test. The surface roughness of the three materials was tested. The microstructure and composition of the three materials were characterized by SEM, EDS and XRD. The results show that the surface of GR1 and GR2 is brighter and has no obvious chromatic aberration. The surface chromatic aberration of TA1 is larger. The mechanical properties of TA1 are the best. The tensile strength and yield strength of rolling are 325.19MPa and 271.17MPa, respectively, and the lateral direction is 329.19MPa and The roughness of 303.15MPa, GR1 and GR2 is slightly lower than that of TA1. The black area on the surface of TA1 is loose and the oxygen content is high. The pole figure of GR1, GR2 and TA1 are obtained.

Print-Scan Resilient Binary Map Watermarking Based on DCT and Scrambling

This article describes how combing the characteristics of simple textures and uneven black area distribution of a binary map, a novel blind print-scan resilient watermarking scheme is proposed. First, the flipping probability of each pixel is calculated, and then the image characteristic value matrix is obtained by scrambling and partitioning. Second, a DCT transform is performed on the characteristic value matrix and then the DCT coefficients are modified according to the hidden data. After that, an inverse DCT is made to the modified DCT coefficient matrix, and the pixels of the corresponding block are flipped. Finally, the watermarked map is obtained by inverse scrambling. Experimental results and analysis show that the proposed scheme not only provides a large capacity and good imperceptibility, but also can resist the impact of a print-scan operation, and has strong robustness. Meanwhile, compared with the existing algorithms, it has a low implementation complexity and can be applied to military maps, engineering design drawings and other binary images.
