A hybrid system for identifying the presence of clouds on the horizon line

Common passive surveys for the presence of clouds in the sky are carried out using the digital processing of photographs taken using fish-eye type lenses. Another type of survey is carried out using active measuring systems, e.g. thermal imaging, active laser distance sensors, etc. A common feature of these sensors is the high cost of the measuring apparatus, which is hardly acceptable for small local short-term weather forecasting stations. The main task of these weather stations is to forecast local dynamic weather phenomena that have (or may have) an impact on the use or operation of technical facilities (e.g. photovoltaic farms, cranes, etc.) or agricultural plant protection measures. This paper proposes a hybrid method for detecting clouds and predicting changes in cloud cover on the horizon line. The proposed method is based on an analysis of colour photographs of the cross-section of the sky using chrominance distribution by the RGB method. In the next step, the CCT colour temperature and the ALS-based ambient light intensity resulting from spectral analysis are determined for the cross-section of the sky being identified. The survey results indicate the dependence of the variability of CCT and ALS parameters for classifying objects on the horizon line. The above analysis makes it possible to distinguish the sky on the horizon, a cloud, or agglomeration elements. The data obtained from the surveys show that the proposed structure of the hybrid system for analysing the presence and movement of clouds on the horizon line can provide the basis for further development of data processing algorithms for a passive sensor of the apparatus for detecting clouds and other objects on the horizon line.

Бумажно-денежные знаки 1924-го года Военно-Потребительского Общества Азербайджанской Стрелковой Дивизии

This paper investigates the history, color photos, and illustrations of the paper notes printed by the Military Consumption Society under the Caucasian Shooting Division for the first time in early 1924. Considering that there has not been sufficient research on this area and the uniqueness of the materials, the authors obtained new scientific findings by providing detailed notaphilic information. In the initial section, the paper presents the history of the First Iron Shooting Regiment named after 26 Baku Commissars and the Third Caucasian Shooting Regiment, pertaining to the Azerbaijan Shooting Division, as well as discusses the role of the Military Consumption Society in providing financial support to the staff members of the division. It also includes photos of personalities distinguished by their activities and services. In the following sections of the paper, the issuers, denominations, characteristics, and various aspects of the main factual material of the research are covered. Materials added to these sections are the crest stamp of the First Iron Shooting Regiment Model Unit on loan checks printed in early 1924, additional stamps, and illustrations of the check of the Third Caucasian Shooting Regiment under the Azerbaijan Shooting Division. The paper catalogues, which has never been done before, the banknotes belonging to the Military Consumption Society of the Azerbaijan Shooting Division. Paper money tokens consumed by the Military Consumption Society of the Azerbaijan Shooting Division in 1924 are rare and unique facts. In modern collection circulation, such materials and copies are few, and those in complete condition are rare (especially checks of the Third Caucasian Shooting Regiment). They were in circulation for a short period of time, and at a later stage, they were taken out of use and completely destroyed.

Taxonomic and nomenclatorial revision of the Neotropical genus Phaeoxantha Chaudoir (Coleoptera: Cicindelidae).

Taxonomic and nomenclatorial revision of the Neotropical tiger beetle genus Phaeoxantha Chaudoir, 1850 (originally Megacephala Latreille, 1802) is presented. Ammosia Westwood, 1852 (with type species Megacephala bifasciata) is confirmed as a junior synonym of Phaeoxantha. The results by Naviaux (2008), who rectified commonly confused taxonomy and nomenclature of Phaeoxantha nocturna (Dejean, 1831) and P. laminata (Perty, 1830) versus P. limata, based on Megacephala limata Perty, 1833 which is an unjustified emendation by Perty (1833) in Perty (18301833), are confirmed the date of the unjustified emendation is newly rectified here. Megacephala laminata Perty, 1830 is confirmed as the type species of Phaeoxantha. Lectotype of Megacephala nocturna Dejean, 1831 is designated here, based on syntypes from the Dejean-Chaudoir collection in MNHN. The genus is subdivided here into two clearly differentiated subgenera: Phaeoxantha (Phaeoxantha) and Phaeoxantha (Euphaeoxantha) subgen. nov. The nominotypical subgenus is represented by Phaeoxantha laminata (Perty, 1830), P. (P.) nocturna (Dejean, 1831), P. (P.) nocturna crassipunctata ssp. nov., P. (P.) paranocturna sp. nov., P. (P.) epipleuralis W. Horn, 1923, P. (P.) tremolerasi (W. Horn, 1909), P. (P.) cruciata (Brull, 1837) and P. (P.) bifasciata (Brull, 1837). The latter, based on Megacephala bifasciata Brull, 1837, was published by Brull in order to rectify the concept of Megacephala aequinoctialis sensu auctorum, (primarily sensu Dejean 1825, 1833, 1836), which has been commonly yet incorrectly treated in literature as Phaeoxantha aequinoctialis aequinoctialis (Dejean, 1825). Although Dejean (1825) clearly characterized the same Megacephala species, his act cannot be interpreted as a valid description under Article 12 of the ICZN (1999), because he explicitly referred to the publications by Linnaeus (1763) and redescription by Fabricius (1775). Therefore, his act must be interpreted as a misidentification and subsequent usage of the name Cicindela aequinoctialis Linnaeus, 1763, which is in fact a bombardier beetle (Brachinini, Carabidae), presently known as Pheropsophus aequinoctialis (Linnaeus, 1763), misidentified by Dejean as Megacephala. In contrast, the name Megacephala bifasciata Brull, 1837 was validly published, supported by a rather appropriate illustration and preserved type specimen, being also in common use to the present day; therefore, the confused name aequinoctialis cannot be preserved and is considered an unavailable name being excluded here from Megacephalini and Cicindelidae. The new subgenus Phaeoxantha (Euphaeoxantha) subgen nov. (type species Megacephala testudinea Klug, 1834) comprises following five species: P. (E.) testudinea (Klug, 1834), P. (E.) klugii (Chaudoir, 1850), P. (E.) bucephala (W. Horn, 1909), P. (E.) wimmeri (Mandl, 1958) and P. (E.) lindemannae (Mandl, 1964). Keys to the two subgenera and to their species, descriptions or differential diagnoses and colour photographs of the habitus and of characters of available type specimens of all species of the genus, as well as the variability and characters of individual populations, are presented and their distribution discussed.

Fimbristylispachmarhiensis (Cyperaceae), a new species from central India

A new species, Fimbristylis pachmarhiensis (Cyperaceae), is described and illustrated from Pachmarhi Biosphere Reserve of Hoshangabad district, Madhya Pradesh, India. This new species bears resemblance to its closest morphological relatives, F. aestivalis and F. griffithii, but differs from both by a combination of characters, primarily including its slender culm, exceptionally lax inflorescence, cylindrical spikelets, triquetrous structure, and the presence of fine hairs covering the entire length of the style. Additionally, the achenes of this species exhibit sparse tuberculation and have a depressed apex. A detailed description, phenology, distribution, IUCN conservation status, a comparative analysis contrasting F. pachmarhiensis with its closely related species, relevant taxonomic notes and colour photographs are provided.

A New Reading of the Bactrian Part of the Dašt-i Nāwur Trilingual (DN I)

Abstract The trilingual Kushan royal inscription of Dašt-i Nāwur has been the subject of scholarly controversies since the time of its first scientific publication (Fussman 1974), with different authors defending opposing views and mutually incompatible readings, in particular of the Bactrian part of the inscription (e.g. Davary & Humbach 1976; Sims-Williams & Cribb 1996; Fussman 1998). Progress in the understanding of the inscription has been hampered by inadequate photographic documentation, but also by the comparatively small amount of information on the Bactrian language that was available at the time of its first publication. A color photograph of the Bactrian inscription probably taken in 1969, which was unavailable to earlier editors, has now been made publicly accessible by the Collège de France as part of the estate of the late Gérard Fussman. This article presents a new reading of the inscription based on this photograph, diverging in many respects from earlier interpretations. It includes a response to the recent re-edition of Palunčić et al. (2023), who have also taken the new photograph into account but reached different conclusions.

Phylogenetic analysis, morphological studies, element profiling, and muscarine detection reveal a new toxic Inosperma (Inocybaceae, Agaricales) species from tropical China.

Tropical Asian collections of Inosperma are usually poisonous mushrooms that have caused many poisoning incidents. However, the species diversity and the toxic mechanisms of these Inosperma species are still unclear. In this study, we describe the discovery of Inosperma wuzhishanense sp. nov. from Wuzhishan City, Hainan Province, tropical China. The new species was identified based on morphological and multi-locus (ITS, nrLSU, and RPB2) phylogenetic analyses. The new species is characterized by its reddish-brown pileus, fibrillose stipes with finely protruding fibrils, rather crowded lamellae, smooth and ellipsoid basidiospores, and mostly clavate, thin-walled cheilocystidia. The new species is phylogenetically nested in the Old World tropical clade 2 and is sister to the tropical Indian taxa I. akirnum. Detailed descriptions, color photos of the new species, and comparisons with its closely related species are provided. Additionally, the muscarine content of the new species was analyzed by ultra-performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS). The muscarine contents ranged from 4,359.79 ± 83.87 mg/kg to 7,114.03 ± 76.55 mg/kg, 2,748.37 ± 106.85 mg/kg to 4,491.35 ± 467.21 mg/kg, and 2,301.36 ± 83.52 mg/kg to 2,775.90 ± 205.624 mg/kg in the stipe, pileus, and lamellae, respectively. The elemental composition and concentration were determined using inductively coupled plasma-mass spectrometry (ICP-MS). A total of 24 elements were detected. Among the heavy metals detected, arsenic showed the highest level of toxicity with a concentration of 36.76 ± 0.43 mg/kg.

Abstract PR001: Radiation dose estimates via live, optical imaging are highly dependent upon patient skin tone

Abstract Introduction: New medical technologies must be tested across diverse populations to ensure efficacy for all patients. In the last decade, a novel technique for imaging in vivo radiation dose was developed to mitigate clinical radiotherapy (RT) incidents. Named Cherenkov imaging (CI), this technology captures the inherent light emission from ionizing radiation interacting with tissue during RT and allows for spatial verification of dose across a patient surface compared to their plan. Recent efforts have been made to use CI to quantitatively assess the true dose delivered across a patient’s surface in real-time, but many patient-specific factors prevent developing a direct Cherenkov-to-dose calibration until addressed. Melanin, a known absorber of light including Cherenkov wavelengths, is the most influential. Early phantom studies showed a near 45% change in emission across a range of skin tones for the same dose. Up until now, further investigation into this effect has been limited to phantoms due to a low number of in vivo CI studies and predominantly Caucasian catchment area demographics. We present a first detailed analysis of imaging patients with a wider range of skin tones and quantifying the effect that it has on dose estimation errors. Methods: A multi-institutional partnership was developed to expand patient demographics and increase diverse skin tone representation. All CI was completed with time-gated iCMOS cameras that capture the low light emission from tissue during RT. Cherenkov images were normalized by absolute planned dose and bulk tissue heterogeneities to minimize non-linear effects outside of skin tone. Patients were initially categorized by ethnicity and their skin tones were quantified by analysis of calibrated color photography. Average Cherenkov light intensity per dose was compared across various skin tones towards developing a calibration system for quantifying dose from the corrected signals. Results: In vivo Cherenkov images exhibit a nearly 220% decrease in signal across a range of skin tones, from White to Black/African American patients, greatly affecting the Cherenkov-to-dose calibration. However, a linear correlation exists between quantitative skin luminosity and dose-normalized Cherenkov emission. Thus, quantifying skin luminosity provides a method to normalize out the effect of skin tone and minimize the in vivo dose estimation errors across diverse patient demographics. Conclusion: This study addresses the critically important issue of developing optical tools that are appropriately calibrated for all skin tones. In vivo CI must be calibrated by skin tone for dosimetric assessments. We have shown that it is not only feasible to image dark skin patients, but possible to quantify the effect that a range of skin tones has on CI for a given dose. Using this information, we can develop a skin tone normalization algorithm to minimize dose estimation errors. Future work will focus on expanding our patient dataset to even darker skin tones through active recruitment efforts in the participating clinics.

GAMMA challenge: Glaucoma grAding from Multi-Modality imAges.

Glaucoma is a chronic neuro-degenerative condition that is one of the world's leading causes of irreversible but preventable blindness. The blindness is generally caused by the lack of timely detection and treatment. Early screening is thus essential for early treatment to preserve vision and maintain life quality. Colour fundus photography and Optical Coherence Tomography (OCT) are the two most cost-effective tools for glaucoma screening. Both imaging modalities have prominent biomarkers to indicate glaucoma suspects, such as the vertical cup-to-disc ratio (vCDR) on fundus images and retinal nerve fiber layer (RNFL) thickness on OCT volume. In clinical practice, it is often recommended to take both of the screenings for a more accurate and reliable diagnosis. However, although numerous algorithms are proposed based on fundus images or OCT volumes for the automated glaucoma detection, there are few methods that leverage both of the modalities to achieve the target. To fulfil the research gap, we set up the Glaucoma grAding from Multi-Modality imAges (GAMMA) Challenge to encourage the development of fundus & OCT-based glaucoma grading. The primary task of the challenge is to grade glaucoma from both the 2D fundus images and 3D OCT scanning volumes. As part of GAMMA, we have publicly released a glaucoma annotated dataset with both 2D fundus colour photography and 3D OCT volumes, which is the first multi-modality dataset for machine learning based glaucoma grading. In addition, an evaluation framework is also established to evaluate the performance of the submitted methods. During the challenge, 1272 results were submitted, and finally, ten best performing teams were selected for the final stage. We analyse their results and summarize their methods in the paper. Since all the teams submitted their source code in the challenge, we conducted a detailed ablation study to verify the effectiveness of the particular modules proposed. Finally, we identify the proposed techniques and strategies that could be of practical value for the clinical diagnosis of glaucoma. As the first in-depth study of fundus & OCT multi-modality glaucoma grading, we believe the GAMMA Challenge will serve as an essential guideline and benchmark for future research.

MITOS ILUSTRASI FOTO FERDI SAMBO DALAM PEMBERITAAN MEDIA ONLINE

In today's information technology era, modern society is greatly spoiled by the ease of access to news. One of the information media is online media reporting, which offers news content in written form as well as color photo illustrations, making it easier for readers to understand the content of the news. However, photo illustrations as news content can sometimes be confusing, such as in the reporting of the premeditated murder committed by Ferdi Sambo. Therefore, it is important to deeply understand the meaning of the photo illustrations from the news content about Ferdi Sambo so as not to be trapped in a superficial interpretation of a news story. The interpretation of Ferdi Sambo's photo illustrations in online media uses a qualitative methodology with a semiotic approach by Roland Barthes regarding denotation and connotation meanings. The results of the analysis conducted on the photo illustrations of Ferdi Sambo in online media reporting indicate that some objectives and interests can be concluded as resistance or defense conducted through body gestures and fashion to address the case being faced.

Morphology and molecular phylogeny of Neolentinus in northern China.

Neolentinus is a significant genus, belonging to Gloeophyllaceae, with important economic and ecological values, which are parasites on decaying wood of broad-leaf or coniferous trees, and will cause brown rot. However, the taxonomic study is lagging behind to other groups of macrofungi, especially in China. In view of this, we conducted morphological and molecular phylogenetic studies on this genus. We have discovered new types of cheilocystidia and with extremely long lamellae in Neolentinus, and, thus proposed it as a new species-Neolentinus longifolius. At the same time, we clarified the distribution of Neolentinus cyathiformis in China and provided a detailed description. Moreover, we also described two common species, viz. Neolentinus lepideus and Neolentinus adhaerens. All the species are described based on the Chinese collections. The key to the reported species of Neolentinus from China is provided. And the phylogeny of Neolentinus from China is reconstructed based on DNA sequences of multiple loci including the internal transcribed spacer (ITS) regions, the large subunit nuclear ribosomal RNA gene (nLSU), and the translation elongation factor 1-α gene (tef-1α). In addition, full morphological descriptions, illustrations, color photographs, taxonomic notes, and all the available sequences of Neolentinus species are provided.

Blackwellomyces kaihuaensis and Metarhizium putuoense (Hypocreales), Two New Entomogenous Fungi from Subtropical Forests in Zhejiang Province, Eastern China

Entomogenous fungi are one of the most diverse fungal groups among ascomycetes. During investigations of macro-fungi biodiversity in Kaihua and Putuo in Zhejiang Province, China, in 2021, several entomopathogenic fungal specimens were collected from subtropical forests. After a careful examination of morphology and multi-gene phylogenetic analyses applying nrSSU, nrLSU, tef1, rpb1 and rpb2, two novel species were discovered, described herein as Blackwellomyces kaihuaensis and Metarhizium putuoense, and further compared with other similar species. Detailed descriptions, color photographs of fresh specimen and figures illustrating microscopic features of the two new species are provided.

Continental fishes of Nicaragua: diversity, distribution and conservation status; with an annotated and illustrated checklist of species and an identification guide to families.

Based on a combination of intensive literature review, electronic database searches, re-identification of museum specimens, and fieldwork, we provide an updated checklist of the continental fishes of Nicaragua. This checklist, systematically arranged at the ordinal and familial level, includes nomenclatural revisions, distributional information, conservation status, and when appropriate, cross-references to previous lists and revisionary works on the fish fauna of the country and region (Central America); illustrations and descriptions to the family level and color photographs of some representative species are also included. According to our results, the native Nicaraguan continental fish fauna is composed of 244 species, divided into 111 genera, 45 families, 24 orders, and two classes; increasing by 60 (i.e., 32.6%) the number of species originally reported by Villa (1982; i.e., the most comprehensive work published to date). The majority of the Nicaraguan native continental fish species, according to their supposed tolerance to salinity, are peripheral (68.9%), followed by secondary freshwater fishes (23.8%), and primary freshwater fishes (only 7.4%). Fish diversity in the 19 major river basins ranged between 21 and 90 species (mean = 58 species, median = 60); the Escondido (Es; 87 species), in the Atlantic, and the Pacfico de Nicaragua (PN; 90), in the Pacific, presented the highest species richness. Most species (188) are restricted to elevations between 0 and 100 meters above sea level (masl); only a few species (18), in contrast, were found at elevations greater than 500 masl (up to 780 masl). Fourteen species in this revision are listed as endemic to Nicaragua. Regarding their conservation status, 22 species (9.0%) are categorized, according to the International Union for Conservation of Nature (IUCN), as Data Deficient, 186 (76.2%) as Least Concern, and seven (2.9%) as Near Threatened; while 24 species (9.8%) are listed as Threatened, thirteen (5.3%) as Vulnerable, two (0.8%) as Endangered, and nine (3.7%) as Critically Endangered. Five species (2.0%) have not yet been evaluated. Six exotic species are also reported. Our results provide a framework for future taxonomic and biogeographic works on fishes from this country and region (Central America), particularly by providing up-to-date knowledge on nomenclature and distributions. In addition, the data provided in this revision will help to monitor fish distributional changes in the future due to human introductions and global change and will aid in conservation decisions concerning Nicaraguan continental fishes.

Four New Species of Strobilomyces (Boletaceae, Boletales) from Hainan Island, Tropical China.

Strobilomyces, one of the most noticeable genera of Boletaceae (Boletales), is both ecologically and economically important. Although many studies have focused on Strobilomyces in China, the diversity still remains incompletely understood. In the present study, several collections of Strobilomyces from Hainan Island, tropical China were studied based on morphology and molecular phylogenetic analyses. Four species are described as new, viz. S. baozhengii, S. conicus, S. hainanensis, and S. pachycystidiatus. Detailed descriptions, color photos of fresh basidiomata, and line drawings of microstructures of the four species are presented.

Increasing linguistic and prelinguistic communication for social closeness during naturalistic AAC instruction with young children on the autism spectrum

This study examined the effects of an intervention package using high-tech augmentative and alternative communication (AAC) with Naturalistic Instruction (NI), time delay, and prompting during social routines for preschoolers on the autism spectrum. The AAC was a communication application on a tablet programmed with color photo representations of participants and communication partners engaged in social routines. The primary dependent measure was a linguistic communication turn on the AAC device completing the instructor’s cloze phrase related to the routine. A secondary dependent measure was prelinguistic communication –nonspecific vocalizations and smiling – within each turn of the routine. Results indicated that all communication types increased and maintained for all three participants with two participants meeting mastery criteria within the minimal number of sessions. These results are significant in providing additional evidence for the effectiveness of AAC intervention beyond teaching simple object requests and in teaching more socially meaningful communication to children on the autism spectrum. Additionally, this study supports the use of color photo representations to promote social interaction. Future research should continue to evaluate such interventions on a larger scale and include naturally occurring communication partners, such as siblings and peers.

Synotisjinpingensis (Asteraceae, Senecioneae), a new species with white ray florets from southeastern Yunnan, China.

Synotisjinpingensis (Asteraceae, Senecioneae), a new species from Jinping county in southeastern Yunnan province, China, is described and illustrated. This species is distinguished by having white ray florets in the genus Synotis, in which only species with yellow ray florets have been hitherto known. In habit and leaf shape S.jinpingensis is most closely similar to S.duclouxii, a species occurring in southwestern Guizhou, southern Sichuan and northeastern Yunnan, China, but differs, in addition to the color of ray florets, by having fewer lateral veins of leaves, obviously longer bracts of calyculus, and larger phyllaries. The membership of the new species within Synotis is strongly corroborated by evidence from floral micromorphology and phylogenetic analyses based on ITS sequence data. Color photographs of living plants, a distribution map, and provisional IUCN status of S.jinpingensis are provided.

Four New Endophytic Apiospora Species Isolated from Three Dicranopteris Species in Guizhou, China.

Endophytic fungi isolated from medicinal ferns serve as significant natural resources for drug precursors or bioactive metabolites. During our survey on the diversity of endophytic fungi from Dicranopteris species (a genus of medicinal ferns) in Guizhou, Apoiospora was observed as a dominant fungal group. In this study, seven Apiospora strains, representing four new species, were obtained from the healthy plant tissues of three Dicranopteris species-D. ampla, D. linearis, and D. pedata. The four new species, namely Apiospora aseptata, A. dematiacea, A. dicranopteridis, and A. globosa, were described in detail with color photographs and subjected to phylogenetic analyses using combined LSU, ITS, TEF1-α, and TUB2 sequence data. This study also documented three new hosts for Apiospora species.

Bulbophylum sect. Cirhopetallum s. str. (Orchidaceae) in Vietnam with the description of a new species, B. thangii, and a new national record, B. fenestratum

The taxonomical survey of Bulbophyllum sect. Cirhopetallum s. str. with the key for identification of all four species occurring in Vietnam is presented. Bulbophylum thangii, belonging to this section and discovered in Khanh Hoa Province, southern Vietnam, is described as a new species for science. The new species shares prominent tooth on the inner side of stelidia with all species in its section but differs from them in warty or colliculate sepals and lip. Bulophyllum fenestratum from the same section is reported from Dong Nai Province as a new national record for the orchid flora of Vietnam. All species in the section are illustrated by plates with analytical color photos. Data on types, habitat, phenology, distribution, taxonomic remarks, and lists of studied specimens are reported for all species as well.

It grows under Salix bebbiana and occurs in southeast Altay Mts. We present detailed descriptions with color photos of fresh fruiting bodies, SEM photos of spores, molecular phylogeny, and an analysis of the characteristic nucleotide sequences compared to the related species.

Mending Memory by Hand and Brush: Socialist China's Colored Photographs

A remarkable quality of Chinese vernacular photographs during the socialist period is their efflorescence of color. From studio colorists well-versed in the art of potassium cyanide to private brushstrokes in thick marker, the prevalence of photo-coloring (zhuose) evidenced a marked degree of dissatisfaction with an unmanipulated print. Bracketed by Chinese photo studios’ national institutionalization in 1956 and the promulgation of commercial color rolls in the 1980s, this discussion builds from extant scholarship on Chinese vernacular photographs of the 1960s and 1970s. By analyzing colored Tiananmen photographs of the Cultural Revolution, a posthumous biography of photo-colorist Zhou Qi, and various examples from the volume Anonymous Photos (Yiming zhao), this article demonstrates that photo-coloring was a crucial aesthetic agent in negotiations between officially mandated postures and bold ways of inscribing individual experiences as chromatic repositories of memory and meaning, marking a site where mass visuality and more specific imaginations of the self collided into color.
