Concept of searching for anchor goods based on the study of commodity indices

The article is devoted to the search for anchor goods — goods whose prices are forming for the prices of groups of goods. The role of the desired anchor product is similar to the role of the anchor currency. The identification of such anchors will allow us to understand the pricing structure, which is presumably of a self-affinity nature. The authors believe that there are several options for why a particular product becomes an anchor: historical, cultural or economic. To identify the main requirements for the anchor product, the behavior and dynamics of price changes of goods included in the CRB index were analyzed. Attention to this index is due, firstly, to its complex but significant role in setting exchange rates, and secondly, its role in analyzing world markets. The CRB index is an indicator of trends in the global commodity market. It displays all the movements and changes in the structure of the world commodity market. The characteristic patterns in the behavior of the goods in question are revealed. Typical phase portraits of their relational series for CRB index products have been revealed. The goods included in the CRB index were regrouped according to the similarity of their behavior relative to each other. Four groups were obtained, within each of which phase portraits of relational time series based on a pair of goods have a similar appearance. Reference phase portraits are described. The basic rules of the anchor product search are formulated based on the study of goods included in the selected commodity index. The conceptual proposals for the search for anchor goods using commodity indexes are formulated Based on the proposed approach, some products were investigated and their ability to play the role of an anchor was evaluated.

Seabird Tissue Archival and Monitoring Project (STAMP) Data from 1999-2010

The multi-entity, long-term Seabird Tissue Archival and Monitoring Project (STAMP) has collected eggs from various avian species throughout the North Pacifc Ocean for over 20 years to create a geospatial and temporal record of environmental conditions. Over 2,500 samples are currently archived at the NIST Biorepository at Hollings Marine Laboratory in Charleston, South Carolina. Longitudinal monitoring efforts of this nature provide invaluable data for assessment of both wildlife and human exposures as these species often consume prey (e.g., fish) similar to, and from sources (e.g., oceanic) comparable to, human populations nearby. In some areas, seabird eggs also comprise a signifcant part of subsistence diets providing nutrition for indigenous peoples. Chemometric profles and related health implications are known to differ across species. Eggs, however, can be diffcult to assign to a species unless the bird is observed on the nest from which the sample was collected due to similar appearance within a genus and sympatric nesting behavior. This represents a large point of uncertainty for both wildlife managers and exposure researchers alike.

Do MURaM and STAGGER Simulations of Solar Faculae Match Observational Signatures from Magnetic Structures?

We compare results of simulations of solar facular-like conditions performed using the numerical codes MURaM and STAGGER. Both simulation sets have a similar setup, including the initial condition of ≈200 G vertical magnetic flux. After interpolating the output physical quantities to constant optical depth, we compare them and test them against inversion results from solar observations. From the snapshots, we compute the monochromatic continuum in the visible and infrared, and the full Stokes vector of the Fe i spectral line pair around 6301–6302 Å. We compare the predicted spectral lines (at the simulation resolution and after smearing to the HINODE SP/SOT resolution) in terms of their main parameters for the Stokes I line profiles, and of their area and amplitude asymmetry for the Stokes V profiles. The codes produce magnetoconvection with similar appearance and distribution in temperature and velocity. The results also closely match the values from recent relevant solar observations. Although the overall distribution of the magnetic field is similar in both radiation-magnetohydrodynamic (RMHD) simulation sets, a detailed analysis reveals substantial disagreement in the field orientation, which we attribute to the differing boundary conditions. The resulting differences in the synthetic spectra disappear after spatial smearing to the resolution of the observations. We conclude that the two sets of simulations provide robust models of solar faculae. Nevertheless, we also find differences that call for caution when using results from RMHD simulations to interpret solar observational data.

An alternate novel approach to classify lip prints

Background The wrinkles and grooves present on the sulci labiorum of human lips form characteristic patterns. As previous authors claimed, these can be used for personal identification in forensic cases because they are unique, permanent, and classifiable. Many scientists had devised different systems to classify the lip prints (Suzuki and Tsuchihashi, Martin Santos, Renaud, Afchar Bayar, and Jose Maria Dominguez). These systems were based solely on the shape of patterns present on the whole lip. However, sometimes, lip prints affected by either habitual smoking or any other pathological conditions are encountered. The investigator may have to form an opinion on partial lip print to identify the culprit. Therefore, in the present study, an alternative comprehensive system to classify even the partial prints has been proposed. Lip print samples were collected from 500 individuals (400 females and 100 males, respectively) using the tape lifting method. The whole lip print (Klein’s zone) was divided into 10 quadrants (five each on upper and lower lips) to study the whole pattern area thoroughly. The sample-wise and quadrant-wise frequency of all the patterns was statistically calculated. Sexual dimorphism of the lip print patterns was also assessed statistically. Results The method used emphasizes the consistency of patterns, which have been divided into Basic and Combination Patterns. Detailed examination of lip prints revealed that all the quadrants tend to have 7 types of Basic Patterns and 43 types of Combination Patterns despite similar appearance. These patterns can be further categorized into various subtypes based on the direction and orientation of wrinkle lines constituting the original pattern. Most of the Basic and Combination Patterns were widely distributed in all the analysed lip print samples and showed significant dependence on the sex of the subject. Conclusions The lip print patterns examined in the present study can be useful as an alternative to the existing systems to classify even partial lip marks recovered at the crime scene.

Abstract 16848: The Effect Of Rhabdomyomas On Underlying Cardiomyopathy: A Case Report

Case Presentation: Term male infant born to SARS-CoV-2 positive mother with infant testing negative. ECG for perinatal bradycardia revealed ventricular pre-excitation. Echocardiogram showed asymmetric LV hypertrophy with prominent trabeculations, subaortic narrowing with no pressure gradient, and normal biventricular systolic function. Rapid increase in RV pressure estimates and NT-proBNP in first week if life concerning for diastolic dysfunction. Anti-arrhythmic therapy initiated for SVT with subsequent resolution. Later, developed progressive LV dilation and systolic dysfunction. Myocardium showed regions resembling non-compaction and others concerning for infiltrative process. Cardiac MRI showed no obvious tumors, but rhabdomyomas could not be ruled out given similar appearance to myocardium. Due to worsening heart failure, everolimus therapy initiated to target potential rhabdomyomas while awaiting genetic testing for tuberous sclerosis. Subaortic narrowing and LV hypertrophy improved within days, and LV appearance became more consistent with non-compaction. Genetic testing revealed a TSC2 gene variant consistent with tuberous sclerosis. Systolic function improved, and patient discharged on afterload reduction. Echocardiogram 6 months post-discharge shows continued LV dilation and mild systolic dysfunction. Discussion: Although outflow obstruction and arrhythmias are common with cardiac rhabdomyomas and can cause dysfunction, our patient developed progressive dysfunction in the absence of outflow tract gradient or prolonged arrhythmia. As rhabdomyomas subsided, it became clearer that he had an underlying cardiomyopathy. We suspect that rhabdomyomas in the setting of abnormal myocardium led to abnormalities in myocardial contractility and compliance causing combined systolic and diastolic dysfunction. After complete resolution of rhabdomyomas, cardiac function has improved. However, he continues to have ventricular dilation and mild dysfunction attributable to cardiomyopathy. It is unlikely that mother’s SARS-CoV-2 infection played a role as infant tested negative and clinical picture was not consistent with myocarditis.

Multi-Class Parrot Image Classification Including Subspecies with Similar Appearance

Owing to climate change and human indiscriminate development, the population of endangered species has been decreasing. To protect endangered species, many countries worldwide have adopted the CITES treaty to prevent the extinction of endangered plants and animals. Moreover, research has been conducted using diverse approaches, particularly deep learning-based animal and plant image recognition methods. In this paper, we propose an automated image classification method for 11 endangered parrot species included in CITES. The 11 species include subspecies that are very similar in appearance. Data images were collected from the Internet and built in cooperation with Seoul Grand Park Zoo to build an indigenous database. The dataset for deep learning training consisted of 70% training set, 15% validation set, and 15% test set. In addition, a data augmentation technique was applied to reduce the data collection limit and prevent overfitting. The performance of various backbone CNN architectures (i.e., VGGNet, ResNet, and DenseNet) were compared using the SSD model. The experiment derived the test set image performance for the training model, and the results show that the DenseNet18 had the best performance with an mAP of approximately 96.6% and an inference time of 0.38 s.

THE SHIP WRECK OF THE LATE 4th / EARLY 3rd CENTURY BC NEAR KINBURN SPIT

During the campaign of 2018 the international underwater archaeological expedition has explored the waters of Tendra Spit and Kinburn Spit on the shelf of the Black Sea, in Mykolaiv and Kherson regions of Ukraine. Underwater archaeological exploration focused on the waters near the northern tip of Tendra Spit, from both the Gulf of Tendra and the sea, and north-western tip of Kinburn Spit. In addition to the visual reconnaissance, divers were using sonar, profiler and side-scan sonar. As a result, the bathymetric map has been compiled. In the initial part of research the work was limited to mapping and taking photographs of the discoveries. During these works was discovered and cleansed the ancient Shipwreck of the late 4th — early 3rd century BC. It was possible to identify the well-preserved fragment of the hull of ancient Wreck of a length of 9.45 m in situ with ballast stones, ceramic material from the cargo, lead plating and him constructions elements. After clearing of the sand from the preserved part of the ship hull with the help of a hydro injector the video and photo documentation was carried out. As a result of these works, large-scale photo mosaic of the object and its 3D-model were made. The condition of the wooden hull is excellent, the technological holes, connections, bronze and iron nails are preserved. Outside of Ukraine several shipwrecks of the same period are attested. The best studied are the following: shipwreck of the 3rd century BC at Grand Congloue, France; the Mazotos shipwreck of the 4th century BC in Cyprus; the Porticello shipwreck of the end of the 5th or beginning of the 4th century BC in Italy; the Alonnisos shipwreck from the end of the 5th century BC, Greece; the Kyrenia shipwreck from the end of the 4th — beginning of the 3rd centuries BC in Cyprus. In the Black Sea, in 2011 a shipwreck from the end of the 4th — beginning of the 3rd centuries BC near Eregli, Turkey (ancient Herakleia Pontica) was discovered by a deep-sea expedition of the research vessel «Nautilus» under the direction of Michael Brennan at a depth of 101 m. Most of the known merchant ships of this period were small, ranging from 12 to 17 m (table). Boris Peters provides a reconstruction sketch of the Lake Donuzlav ship of the late 4th — early 3rd centuries BC. It is almost identical to the reconstruction of the Kyrenia merchant ship, based on its hull which was preserved by 75 %, The replica named «Kyrenia 2» was built and made several voyages. It can be assumed that the Kinburn Spit ship found in 2018 was of similar appearance but further research will provide more detailed information.

More examples of breakdown the 1:1 partner specificity between figs and fig wasps

Background The obligate mutualism between fig trees (Ficus, Moraceae) and pollinating fig wasps (Agaonidae) is a model system for studying co-evolution due to its perceived extreme specificity, but recent studies have reported a number of examples of trees pollinated by more than one fig wasp or sharing pollinators with other trees. This will make the potential of pollen flow between species and hybridization more likely though only few fig hybrids in nature have been found. We reared pollinator fig wasps from figs of 13 Chinese fig tree species and established their identity using genetic methods in order to investigate the extent to which they were supporting more than one species of pollinator (co-pollinator). Results Our results showed (1) pollinator sharing was frequent among closely-related dioecious species (where pollinator offspring and seeds develop on different trees); (2) that where two pollinator species were developing in figs of one host species there was usually one fig wasp with prominent rate than the other. An exception was F. triloba, where its two pollinators were equally abundant; (3) the extent of co-pollinator within one fig species is related to the dispersal ability of them which is stronger in dioecious figs, especially in small species. Conclusions Our results gave more examples to the breakdown of extreme specificity, which suggest that host expansion events where pollinators reproduce in figs other than those of their usual hosts are not uncommon among fig wasps associated with dioecious hosts. Because closely related trees typically have closely related pollinators that have a very similar appearance, the extent of pollinator-sharing has probably been underestimated. Any pollinators that enter female figs carrying heterospecific pollen could potentially generate hybrid seed, and the extent of hybridization and its significance may also have been underestimated.

Classification of Cell-in-Cell Structures: Different Phenomena with Similar Appearance

A phenomenon known for over 100 years named “cell-in-cell” (CIC) is now undergoing its renaissance, mostly due to modern cell visualization techniques. It is no longer an esoteric process studied by a few cell biologists, as there is increasing evidence that CICs may have prognostic and diagnostic value for cancer patients. There are many unresolved questions stemming from the difficulties in studying CICs and the limitations of current molecular techniques. CIC formation involves a dynamic interaction between an outer or engulfing cell and an inner or engulfed cell, which can be of the same (homotypic) or different kind (heterotypic). Either one of those cells appears to be able to initiate this process, which involves signaling through cell–cell adhesion, followed by cytoskeleton activation, leading to the deformation of the cellular membrane and movements of both cells that subsequently result in CICs. This review focuses on the distinction of five known forms of CIC (cell cannibalism, phagoptosis, enclysis, entosis, and emperipolesis), their unique features, characteristics, and underlying molecular mechanisms.

Dermatofibrosarcoma protuberans of the breast: A case report of a rare breast tumour

Introduction: Dermatofibrosarcoma protuberans (DFSP) is an intermediate and slow-growing sarcoma, arising most commonly in the trunk and extremities and rarely in the breast. It may be recurrent, but metastasis is rare. Excision with good resection margins reduces the rate of recurrence. Case Presentation: A 28-year-old lady presented with a painless lump in the left breast of 16 years duration. Examination revealed an ulcerated firm mass, well defined, with perilesional nodules on the skin of the breast. Wedge biopsy favoured Borderline Phylloides Tumour over DFSP. Patient was offered mastectomy and the histology of the specimen confirmed Fibrosarcomatous DFSP. Conclusion: This stresses the importance of histology in diagnosing a rare breast tumour. This is very important because it may show similar appearance to other benign and malignant breast lesions, which makes clear the role of pathological investigation to make a definitive diagnosis.
