Kerala: Thiruvananthapuram district, Athirumala, 8.970 N 77.30 E, 1200 m, 08 May 2020 (with flowers), Govind & VSA Kumar 590 (holotype UCBD; isotypes UCBD, KFRI). Diagnosis: — Miliusa agasthyamalana resembles M. wightiana Hooker & Thomson (1855: 285) with respect to solitary flowers, leaves with acuminate apex and ovate shape of the inner petal but is distinct with respect to the size of tree (small tree reaching a height of 9 m in M. agasthyamalana vs. medium sized tree reaching a height of 15 m in M. wightiana), shape of leaves (ovate to ovate lanceolate vs. elliptic-lanceolate), hairiness on secondary veins (glabrous vs. pubescent), length of pedicel (3.0– 5.5 mm vs. 1.5 –2.5 mm), sepals (Ovate or obovate with hair along margin vs. oblong and pubescent throughout.)inner petals (1.5–2.2cm fleshy, yellow with pink stripes or spots vs. 10–15 × 6–8 mm non-fleshy, greenish), staminal connectives (included vs. apiculate), number of carpels per flower (17–22 vs. 10–15) and shape of monocarps (dumbbell-shaped with round apex vs. pisiform with acute apex). The new species also shows resemblance to M. paithalmalayana Josekutty (2016: 287) reported from the Paithalamala range of Western Ghats with respect to the solitary flowers, included staminal connectives and linear carpels but is very distinct with respect to the inner petals (ovate, fleshy, yellow with pink stripes in M. agasthyamalana vs. elliptic to lanceolate, nonfleshy with purple color in M. paithalmalayana), sepals (ovate or obovate with hairs along margin vs. lanceolate, glabrous) number of carpels per flower (18–22 vs. 10–15), shape of monocarp (dumbbell shaped with round apex, green with purple spots vs. oblong, crimson red) Description: —Evergreen trees, 6–9 m high; bark brown, rough, branches terete, drooping, often spreading, young parts gloss, glabrous. Leaves chartaceous, 5.0–16.0 × 1.5–5.0 cm, ovate or ovate lanceolate, unequally rounded at base, wavy and slightly folded along margins, caudate-acuminate at apex, glabrous, subsessile or petiole to 1 mm long, terete, glabrous, black; lateral nerves 6–8 pairs, intramarginal nerves looping; tertiary nerves inconspicuous, nervules obscure, Flowers solitary, pseudo-terminal (slightly above and opposite the terminal leaf) yellowish-pink; pedicels 3.5–5.5 cm long, glabrous, glossy, yellowish to light green; bracts 2, ovate-triangular, acute, ca 0.5 mm long, hairy outside; sepals 3, ca 1.0 × 1.2 mm, ovate-lanceolate, apex acute, adaxial side glabrous in the middle, pubescent along margin; outer petals 3, ovate or obovate, apex acute, hairy along margins, slightly curved inwards, ca 3.0 × 3.5 mm; inner petals 3, ovate or obovate, 1–1.4 × 0.8–1.0 cm, thick ca 1mm long, fleshy, glabrous, thickly hooded on the lower half, cohering when young along margins, yellow with pink streaks inside and pink spots outside; torus ovoid, long with white hairs; stamens 15–20, anthers ca 0.5 mm long, connective included; carpels 17–22, linear in outline, slightly curved, ca 1 mm long, glabrous; stigma obovate-acute, about half the height of the ovary, ovules 1 or 2. Fruiting stalk terete, glabrous, dark brown, 7–9 cm long; monocarps usually 8–15, each 1–1.2 × 1–1.5 cm across, more or less dumbbell-shaped, green with purple stripes. Seeds 1–2. Phenology:— Flowering and fruiting occur during April to July. Etymology:— The specific epithet refers to the type locality, Agasthyamala Biosphere reserve in Thiruvananthapuram District of Kerala, south India. Distribution and ecology:— Miliusa agasthyamalana is known only from the type locality, between 1000–1250 m elevations. It grows in the interior of the evergreen forest range of Athirumala, with a total of two individual only. Each individual is separated by a distance range of 1.5 km. The associated species include Garcinia imberti Bourdillion (1899: 349) (Clusiaceae) and Myristica beddomei King (1891: 327) (Myristicaceae).The type locality Athirumala forms the base station of Agasthyamala biosphere reserve that is rich with moist deciduous forest, semi evergreen forest, grassland, evergreen forest and at the end, large rock formations. It has a unique biodiversity and is noted for the presence of many endemic medicinal herbs. The high conservation value of the area relies on its rich biodiversity, geography and hydrology and hence protected as a biosphere reserve. Taxonomic notes:—The new species is similar to Miliusa campanulate Pierre (1881: 41) group (Chaowasku & Kessler 2013), based on the tightly appressed nature of the inner petals (Chaowasku & Kessler 2013) and Indian species to the Miliusa nilagirica group (Van Heusden 1992) in having recurved inner petals. Miliusa agasthyamalana shows similarity to Miliusa tirunelvelica Murugan, Manickam, Sundaresan & Jothi (2004: 102) with respect to 6–8 pairs of secondary veins in leaf and included connectives but is distinct with respect to many characters summarized in Table 1. Conservation status:— There is only a single population, with about 2 mature individuals, occupying an area of less than 2 km 2. The estimated Extent of Occurrence (EOO) is 25 km 2 and the Area of Occupancy (AOO) is less than 2 km 2. The number of mature individuals is estimated to be two, when considering all the localities. Since these locations are inside a protected area, the likelihood of a decline due to anthropogenic activity is small. Nevertheless, we recommend that the species be categorized as Critically Endangered (CR) in the category [B2a, b(v)] (IUCN 2020). The area is well protected but chances of forest fires pose a high threat to this area. Selected specimen examined (paratypes):— INDIA.

Hölder continuity and Harnack estimate for non-homogeneous parabolic equations
No full textIn this paper we continue the study on intrinsic Harnack inequality for non-homogeneous parabolic equations in non-divergence form initiated by the first author in Arya (Calc Var Partial Differ Equ 61:30–31, 2022). We establish a forward-in-time intrinsic Harnack inequality, which in particular implies the Hölder continuity of the solutions. We also provide a Harnack type estimate on global scale which quantifies the strong minimum principle. In the time-independent setting, this together with Arya (2022) provides an alternative proof of the generalized Harnack inequality proven by the second author in Julin (Arch Ration Mech Anal 216:673–702, 2015).peerReviewe

Diagnosis (Table 7):— Allmania multiflora differs from A. nodiflora in having shorter tepals (2.2–2.5 mm and ovatelanceolate vs. 3.3–3.6 mm long and linear-lanceolate), wider gynoecium [(0.3–) 0.4–0.5 mm vs. 0.2–0.3(–0.4) mm long], the diameter of the seeds (1.5–1.9 mm vs. 2.9–3.7 mm), shorter bracts (1.0– 1.2 mm vs. 2.0– 2.4 mm long), shorter and pubescent peduncle (1.0– 1.3 cm long, pubescent with pointed hairs vs. 2.0– 2.7 cm long, glabrous or sparsely pubescent), a higher number of flowers per inflorescence [(15–)30–44 vs. 3–10), stigma pinkish or violet, protruding beyond the anthers (vs. green, not protruding), hairiness of the seeds (highly pubescent vs. glabrous), aril with protruding setae (vs. without setae). Description (Figs. 7–9):—Annual herb, erect or ascending with branches arising from the base, up to 60 cm long. Stem red to violet at the base, green in the rest, pubescent. Stipules hard and deciduous. Leaves ovate-elliptic or lanceolate (1.0–2.5 × 0.5–1.5 mm), apex obtuse or acute, base attenuate, pubescent at the margin and adaxial surface, veined (5–7 pairs of lateral arcuate veins), petioled (0.5–1.0 cm long). Inflorescence in cymose heads, leaf opposed, peduncled, peduncle 1.0– 1.3 cm long, pubescent. Flowers (15–)30–44 per inflorescence; bracts ovate-lanceolate to linear-lanceolate, 1.0– 1.2 mm long, pubescent, with membranous border, abruptly interrupted at about the half (bracts awned), eglandular; bracteoles lanceolate to narrowly ovate, 2.9–3.6 × 0.5–0.8 mm, awned, pubescent outside at the distal part, glabrous at margins. Tepals 5 lanceolate 5.7–7.3 × 0.5–0.7 mm. Stamens 5, 0.6–2.0 cm long, glabrous, creamy white; filaments basally connate, forming a rim around the gynoecium. Pollen polypantoporate, 15–18 µm in size, pores 2–3, pollen surface spinulose. Ovary ovoid, 4.3–5.8 × (0.3–) 0.4–0.5 mm, usually white (sometimes greenish), glabrous; style 0.1–0.2 cm long, extending beyond the filaments, glabrous; stigma capitate, pinkish-violet. Fruits utricle, light green to white, 1.4–2.0 × 0.6–0.8 mm. Seeds ovate, 1.5–1.9 × 1.7–2.1 mm in size, brownish-black, with aril at the base having protruding setae, surface densely pubescent. Etymology:— The new species name refers to the characteristic occurrence of many flowers in a single glomerule. Distribution (fig. 10), habitat, and phenology:— Allmania multiflora is known from few locations in SW-India (Kerala State), at 1000–1250 m of elevation. The distribution area of the new species partially overlaps that of A. nodiflora in Palakkad and Thiruvananthapuram districts. It grows in open areas of the granite hillocks with 25–30 scattered individuals per population. Each population spreads over an area of nearly 1–2 m 2. Flowering and fruiting times are May to September. Conservation status:— The plant propagates mainly through seeds (rarely by rooting at stem nodes). The number of individuals is very few and prone to severe grazing and repeated fire. The exploitation of taxon as a vegetable is another threat, especially by local people along with amaranths. Following the IUCN Red List Guidelines and Criteria (IUCN 2019), Allmania multiflora is assessed as Critically Endangered (ER) in the category [B2a,b(iii,v)] since AOO is about 30 m 2, locations are 4, and decline observed in the quality of the habitat (iii).

Arya Stark, donzela-guerreira?
No full textThis article addresses in its content an analysis on the character Arya Stark of the literary work, the chronicles of Ice and Fire, of the author George R.R. Martin. For this, the study was directed by the study about gender (GALVÃO, 1998), namely, the understanding of the term damsel-warrior and its importance in relation to social issues pertinent to female experience, especially in the literary description. The purpose of analyzing the character is to establish a debate about the feminine 'image' in the work, through Arya and a comparison with the experience of the woman in the contemporary society, being, therefore, the theoretical concepts, through bibliographical revision On the ethos (AMOSSY, 2014, EGGS, 2014) and the enunciative scene (MAINGUENAU, 2014) help in the argumentative constitution for a better understanding of the discursive types that are in the social core historically and that reflect in the analyzed work. The result of the research, from the studies of the theoretical basis, was convergent to elucidation of the social constitution that the discourse has. Thus, it is relevant to note that understanding how discourses are defined and expressed through literature continues to reveal the barriers that result in occasional domains of groups over others.Este artigo aborda em seu conteúdo uma análise sobre a personagem Arya Stark da obra literária, As crônicas de Gelo e Fogo, do autor George R.R. Martin. Para tanto, o estudo foi direcionado pelo estudo a respeito de gênero (GALVÃO, 1998), a saber, sobre a compreensão do termo donzela-guerreira e de sua importância frente às questões sociais pertinentes a vivência feminina, sobretudo na tradição literária. O propósito de analisar a personagem é de estabelecer um debate a respeito da ‘imagem’ feminina na obra, por meio de Arya e de uma comparação com a vivência da mulher na sociedade contemporânea, sendo assim, os conceitos teóricos, por meio de revisão bibliográfica sobre ethos (AMOSSY, 2014; EGGS, 2014) e da cena enunciativa (MAINGUENAU, 2014) auxiliam na constituição argumentativa para melhor compreensão dos tipos discursivos que estão no cerne social historicamente e que refletem na obra analisada. O resultado da pesquisa, a partir dos estudos da base teórica, foi convergente a elucidação da constituição social que o discurso tem frente à temática. Dessa forma, mostra-se relevante pontuar que compreender como os discursos são definidos e expressos através da literatura continua a revelar os entraves que resultam em ocasionais domínios de grupos sobre outros
A simplified approach to estimate water retention for Sicilian soils by the Arya-Paris model
No full textApplication of the Arya and Paris (AP) model to estimate the soil water retention curve requires a detailed description of the particle-size distribution (PSD) because the scale factor a, relating the pore length of an ideal soil to that of the natural one, depends on the particle size distribution parameters. For a dataset of 140 Sicilian soils that were grouped in five texture groups, the logistic and linear models were applied to evaluate a, and the water retention values predicted by the AP model were compared with the measured ones. Using the parameters proposed by Arya et al. (1999), the two models yielded similar unsystematic root mean error of estimate (RMSEu). Therefore, their potential accuracy was considered comparable. However, the water retention data predicted by the logistic model were more biased (higher systematic root mean error of estimate, RMSEs) than those predicted by the linear model. A calibration was conducted for the logistic model to obtain five sets of parameters specifically developed for Sicilian soils. The calibrated logistic model only minimally improved the prediction accuracy of the AP model. This result also supported the Arya et al.’s procedure (Arya et al., 1999) for soils that were not included in their original calibration dataset. With the aim to simplify AP model application, an alternative procedure was developed by optimizing a soil-specific a value in the range of measured water content values. For Sicilian soils, the optimised values of the scale parameter (OPT) were significantly correlated with clay content and bulk density. The empirical relationship that was obtained for the calibration dataset allowed to estimate the water retention data of the validation dataset (N = 70) with an estimation error (RMSE = 0.042 cm3cm-3) lower than that of the traditional approach based on the logistic model. Therefore, it can be considered as a reasonable alternative to the more complex logistic model for estimating the water retention curve of Sicilian soils
RDD2020: An Image Dataset for Smartphone-based Road Damage Detection and Classification
No full textThe RDD2020 dataset contains 26336 road images collected from India, Japan, and the Czech Republic with more than 31000 instances of road damage. The dataset contains annotation for four damage categories: Longitudinal Cracks(D00), Transverse Cracks(D10), Alligator Cracks(D20), and Potholes(D40); and is intended for developing deep learning-based methods to detect and classify road damage automatically.
The images in RDD2020 were captured using vehicle-mounted smartphones, making it useful for municipalities and road agencies to develop methods for low-cost monitoring of road pavement surface conditions.
Further, the machine learning researchers can use the datasets for benchmarking the performance of different algorithms for solving other problems of the same type (classification, object detection, etc.). For instance, the Global Road Damage Detection Challenge (GRDDC'2020), organized as an IEEE Big Data Cup in 2020, utilized the dataset RDD2020 to evaluate the road damage detection models proposed by the participants. An overview of the challenge is provided in the video https://www.youtube.com/watch?v=8sh70wjn1aI.

Perancangan dan Penerapan Metode K-Means untuk Memprediksi Penjualan Toko Arya Elektrik
No full textIn a shop, the product is a staple that is sold and bought. There are products in the store between products that sell well and products that don't sell. Given this problem, it is necessary to create a system that can classify products that sell, products that sell well, and products that don't sell well, which was carried out at the Arya Elektrik Store and carried out from March to July 2022. The K-Means algorithm is not affected by the order of objects used. used, this is proven when the author tries to randomly determine the starting point of the cluster center of one of the objects at the start of the calculation. The number of cluster memberships generated is the same when using another object as the starting point for the cluster center. However, this only affects the number of iterations performed. The purpose is to create applications and analyze product sales at the Arya Elektrik Store using the K-Means method. With this system, it can provide convenience benefits for analyzing the grouping of product sales at the Arya Elektrik Store, determining and classifying product sales that are selling well, very selling, and less selling. The method used to collect data is observation and interviews. With this application, shop owners can see the results of grouping these products. So, if there are products that don't sell well, shop owners can look for other alternatives so that products that don't sell can be sold.Pada sebuah toko, produk merupakan bahan pokok yang dijual belikan. Produk di toko terdapat antara produk yang laku dengan produk yang tidak laku. Dengan adanya masalah ini, perlu untuk menciptakan sistem yang dapat mengelompokkan produk laku, produk sangat laku, dan produk yang kurang laku, yang dilakukan di Toko Arya Elektrik dan dilaksanakan pada bulan Maret sampai Juli 2022. Algoritma K-Means tidak terpengaruh terhadap urutan objek yang digunakan, hal ini dibuktikan ketika penulis mencoba menentukan secara acak titik awal pusat cluster dari salah satu objek pada permulaan perhitungan. Jumlah keanggotaan cluster yang dihasilkan berjumlah sama ketika menggunakan objek yang lain sebagai titik awal pusat cluster tersebut. Namun, hal ini hanya berpengaruh pada jumlah iterasi yang dilakukan. Tujuan untuk membuat aplikasi dan menganalisis penjualan produk pada Toko Arya Elektrik menggunakan metode K-Means. Dengan adanya sistem ini dapat memberikan manfaat kemudahan untuk menganalisis pengelompokkan penjualan produk pada Toko Arya Elektrik, menentukan dan mengklasifikasikan penjualan produk yang laku, sangat laku, dan kurang laku. Metode yang digunakan pengumpulan data adalah observasi dan wawancara. Dengan adanya aplikasi ini, pemilik toko dapat melihat hasil pengelompokkan produk tersebut. Maka, bila terdapat produk yang tidak laku, pemilik toko dapat mencari alternative lain agar produk yang tidak laku dapat menjadi laku.

Constraints Perceived by the Rural Youth in Adoption of ARYA Project (Attracting and Retaining Youth in Agriculture) Interventions in Telangana State, India
No full textRealizing the prominent role of rural youth in agricultural development especially from the point of view of food security of the country, ICAR has initiated a scheme on "Attracting and Retaining of Youth in Agriculture (ARYA)". This project was launched by the Prime Minister on the foundation day of ICAR in 2015 and implemented through Krishi Vigyan Kendras in 25 states of the country. Under this scheme, special efforts will be taken to attract the rural youth under the age of 35years in agriculture and allied sector so the increase in the migration of rural youth towards cities can be controlled. Krishi Vigyan Kendra, Kampasagar will be the locale of the study because initially ARYA project was implemented through KVKs in 25 states of the country. In Telangana, Nalgonda is the only district in which this project was initiated in 2015. In Nalgonda district, under KVK Kampasagar 60 respondents (beneficiaries of ARYA Project) were selected purposively to study the constraints faced by the beneficiaries in adoption of ARYA interventions. Garrett ranking technique was used to rank the constraints in order of their influence in adopting the ARYA interventions
