Spatio-temporal evolution of wet–dry event features and their transition across the Upper Jhelum Basin (UJB) in South Asia
Authors: Ansari Rubina , Grossi Giovanna
Published: February 2022

Abstract. The increasing rate of occurrence of extreme events (droughts and floods)
and their rapid transition magnify the associated socio-economic impacts
with respect to those caused by the individual event. Understanding of
spatio-temporal evolution of wet–dry events collectively, their
characteristics, and the transition (wet to dry and dry to wet) is therefore
significant to identify and locate most vulnerable hotspots, providing the
basis for the adaptation and mitigation measures. The Upper Jhelum Basin
(UJB) in South Asia was selected as a case study, where the relevance of
wet–dry events and their transition has not been assessed yet, despite
clear evidence of climate change in the region. The standardized
precipitation evapotranspiration index (SPEI) at the monthly timescale was
applied to detect and characterize wet and dry events for the period
1981–2014. The results of temporal variations in SPEI showed a strong change
in basin climatic features associated with El Niño–Southern Oscillation
(ENSO) at the end of 1997, with the prevalence of wet and dry events before
and after 1997 respectively. The results of spatial analysis show a higher
susceptibility of the monsoon-dominated region towards wet events, with more
intense events occurring in the eastern part, whereas a higher severity and
duration are featured in the southwestern part of the basin. In contrast, the
westerlies-dominated region was found to be the hotspot of dry events with
higher duration, severity, and intensity. Moreover, the surrounding region
of the Himalaya divide line and the monsoon-dominated part of the basin were
found to be the hotspots of rapid wet–dry transition events.
Mechanical compaction mechanisms in the input sediments of the Sumatra Subduction Complex- insights from microstructural analysis of cores from IODP Expedition- 362

Published: February 2022

Abstract. The input sediments of the North Sumatra subduction zone margin, drilled during IODP Expedition 362, exhibit remarkable uniformity in composition and grain size over the entire thickness of the rapidly deposited Nicobar Fan succession (sea-floor to 1500 mbsf depth), providing a unique opportunity to study the micromechanisms of compaction. Samples were prepared from dried core samples from sites (U1480 and U1481) by both Ar-ion cross-section polishing and broad-ion beam cutting, and imaged with a field-emission SEM. Shallowest samples (sea-floor to 28 mbsf) display a sharp reduction in porosity from 80 % to 52 % due to collapse of large clay-domain/matrix pores associated with rotation and realignment of clay-platelets parallel to the bedding plane. The deeper succession (28 mbsf to 1500 mbsf) exhibits less rapid reduction in porosity from 52 % to 30 % by the progressive collapse of silt-adjacent larger pores by bending and subsequent sliding/fracturing of clay particles. In addition, there is a correlated loss of porosity in the pores too small to be resolved by SEM. Clastic particles show no evidence of deformation or fracturing with increasing compaction. In the phyllosilicates, there is no evidence for pressure solution or recrystallization: thus, compaction proceeds by micromechanical processes. Increase in effective stress up to 18 MPa (~1500 mbsf) causes the development of a weakly aligned phyllosilicate fabric defined by illite clay particles and mica grains, while the roundness of interparticle pores decreases as the pores become more elongated. We propose that bending of the phyllosilicates by intracrystalline slip may be the rate-controlling mechanism. Pore size distributions show that all pores within the compactional force chain deform, irrespective of size, with increasing compactional strain. This arises because the force chain driving pore collapse is localized primarily within the volumetrically dominant and weaker clay-rich domains; pores associated with packing around isolated silt particles enter into the force chain asynchronously and do not contribute preferentially to pore loss over the depth range studied.
Weakening of the pinning point buttressing Thwaites Glacier, West Antarctica

Published: February 2022

Abstract. The Thwaites Eastern Ice Shelf buttresses a significant portion of Thwaites Glacier through contact with a pinning point 40 km offshore of the present grounding line. Predicting future rates of Thwaites Glacier’s contribution to sea-level rise depends on the evolution of this pinning point and the resultant change in the ice-shelf stress field since the breakup of the Thwaites Western Glacier Tongue in 2009. Here we use Landsat-8 feature tracking of ice velocity in combination with ice-sheet model perturbation experiments to show how past changes in flow velocity have been governed in large part by changes in lateral shear and pinning point interactions with the Thwaites Western Glacier Tongue. We then use recent satellite altimetry data from ICESat-2 to show that Thwaites Glacier’s grounding line has continued to retreat rapidly; in particular, the grounded area of the pinning point is greatly reduced from earlier mappings in 2014, and grounded ice elevations are continuing to decrease. This loss has created two pinned areas with ice flow now funneled between them. If current rates of surface lowering persist, the Thwaites Eastern Ice Shelf will unpin from the seafloor in less than a decade, despite our finding from airborne radar data that the seafloor underneath the pinning point is about 200 m shallower than previously reported. Advection of relatively thin and mechanically damaged ice onto the remaining portions of the pinning point and feedback mechanisms involving basal melting may further accelerate the unpinning. As a result, ice discharge will likely increase up to 10 % along a 45 km stretch of the grounding line that is currently buttressed by the Thwaites Eastern Ice Shelf.
Megadunes in Antarctica: migration and evolution from remote and in situ observations
Authors: Traversa Giacomo , Fugazza Davide , Frezzotti Massimo
Published: February 2022

Abstract. Megadunes are peculiar snow dune fields known to be present only on the East Antarctic plateau and other planets (Mars and Pluto). Antarctic megadunes are climatically important because their leeward flanks are characterized by glazed surfaces, a particular morphogenetic state of snow which makes these zones ablation areas, as their surface mass balance is near-zero or negative, on a continental ice sheet where surface mass balance is on average positive. This work builds on previous efforts in this field and by taking advantage from the most recent remote-sensing products and techniques coupled with field data, aims to provide new information and confirm previous hypotheses about megadunes. Focusing on two sample areas of the East Antarctic plateau where in the past international field activities were carried out (EAIIST and It-ITASE), we analysed the dynamic parameters of megadunes, their albedo and morphology. For the first time we provide a detailed analysis of their upwind migration, in all its components (absolute, sedimentological and ice flow) from remote and field observations, finding absolute values of approximately 10 m a−1 and demonstrating the upwind migration of dune windward flanks, with a relative stability of the leeward faces. Using remote sensing, we analysed their optical characteristics, i.e., albedo (broadband and NIR), brightness temperature and topographic parameters, including slope, aspect and slope along the prevailing wind direction (SPWD). First numerical results about glazed-surface albedo are thus provided, which is found to be lower than the surrounding snow, especially in NIR wavelengths. This detailed information allowed us to perform a precise mapping of glazed surfaces and their evolution and trends over time, demonstrating a general overall intra-annual areal decrease in summer (−16 %) and an inter-annual increase over recent years (at maximum almost +0.2 % per year in January).
An investigation of the applicability of SPIV for the analysis of the dynamics of floating offshore wind platforms
Authors: Belvasi Navid , Judge Frances , Murphy Jimmy , Flannery Brian , Desmond Cian
Published: February 2022

Abstract. There is a need for new numerical tools to capture the physics of floating wind platforms more accurately to refine engineering designs and reduce costs. The conventional measurements apparatus in tank tests, including wave probs, velocity and current profiler, as well as doppler sensors, are unable to give a full 3D picture of velocity, pressure, and turbulence. In tank testing, the use of the underwater stereoscopic PIV method to fully characterise the 3D flow field around floating platforms can provide a rich source of validation data and overcome some of the limitations associated with more classical measurement techniques. This optical technique can be used to accurately measure the random and chaotic structure of turbulent flows around the floater. Moreover, the main characteristics of turbulence of the flow around the floater, such as rotationality, diffusivity, irregularity, as well as dissipation, can be extracted and studied. The underwater S-PIV method has been widely used for marine and offshore applications, including studies on ship and propeller wakes and tidal stream turbines; however, to date, this technology has not seen widespread use for the hydrodynamic study of floating offshore wind turbines. Therefore, in the current study, the key considerations for using S-PIV for this purpose are discussed; meanwhile, the related studies in the field of quantitative flow measurements are reviewed.
The Peasant, The Pagan, and The Christian: Landscape and Cinematic Spectatorship in Michelangelo Frammartino's Le Quattro Volte
Authors: Turan Kaya
Published: February 2022

As human relationships to the natural world become increasingly abstract and antagonistic, the need to find new modes of being and being-in-common is more urgent than ever. This means re-conceptualizing not only human positionality within larger environments and ecologies, but also re-thinking how we understand the world itself. Filmmaker and installation artist Michelangelo Frammartino offers one such re-conceptualization with his 2011 film Le Quattro Volte, in which he sequentially takes up the modes of being of human, goat, tree, and charcoal in the Southern Italian region of Calabria. Frammartino invites the viewer to temporarily dwell in the spatialities, temporalities, and ontological truths of Calabria which include, but exceed human activity. I examine Frammartino’s film through the lens of Jean-Luc Nancy’s essay “Uncanny Landscape,” in which Nancy presents three modalities of engagement with land and world: peasant, pagan, and Christian. Nancy contrasts peasant and pagan engagement with the land, in which the land is understood and co-existed with in accordance with its omni-presence, with Christian relation to landscape in which presence is withdrawn, replaced by absence and distance. I argue that in Le Quattro Volte, Michelangelo Frammartino, with the aid of the viewer, develops a set of representational strategies that signify cinematic “presence”, suggesting a “pagan” mode of spectatorship in which all things (animal, vegetable, and mineral) are revealed as having autonomy, perspective, temporality, and unity. Furthermore, I contend that this “alternative” reality is not self-enclosed, as the film world opens onto the spectatorial world. Le Quattro Volte offers an opportunity for a mode of embodiment that places us in and among the world rather than at a distance.

носії культур доби бронзи – ямної, катакомбної, зрубної та культури
багатопружкової
кераміки. Досліджено комплекс ліпленої кераміки з археологічних
пам’яток Запорізької
й Херсонської областей, що зберігається у фондах Національного
заповідника «Хортиця».
Проаналізовано 23 відносно цілі форми та понад 50 окремих
фрагментів ліплених посудин
з ознаками ремонту, таких як свердління й потовщення
черепка. Під час досліджень враховано, коли
проводився такий ремонт – до чи після
випалювання глиняного виробу, а також хто його проводив
– гончар чи власник
посудини. На виробах з колекції, що вивчалася, зафіксовано такі способи ремонту:
•
замазування тріщин до випалювання з нарощенням товщини черепка;
• свердління
отворів для стягування тріщин або фіксації окремих фрагментів посудини мотузкою
з
рослинних волокон, шкіряним ременем або жилами. Також допускається ймовірність
заповнення
тріщин та незначних за розміром втрачених фрагментів пластичними
матеріалами органічного
й неорганічного походження або їх сумішами (такими як
смола, віск, мул, волога глина, закладання
моху або просмоленого шнура).

Відповідно до трасологічних методів аналізу, досліджуючи форму й особливості
просвердлених
отворів, вдалося простежити й частково реконструювати спосіб
свердління, а також форму
і ймовірний матеріал знарядь; відтворено процес
свердління глиняного черепка за допомогою
крем’яного сколу.
Зроблено висновок
про значну поширеність явища ремонту глиняного посуду серед носіїв
культур племен
бронзи, що було зумовлено кочовим характером життя, браком сировини, палива й,

відповідно, високою цінністю посуду. Загалом, прийоми й методи ремонту залишалися
незмінними
й досить примітивними впродовж усієї доби бронзи.

An expansion based on Sine-Gordon equation to Solve KdV and modified KdV equations in conformable fractional forms
Authors: Hepson Ozlem Ersoy , Korkmaz Alper , Hosseini Kamyar , Rezazadeh Hadi , Eslami Mostafa
Published: February 2022

An expansion method based on time fractional Sine-Gordon equation is implemented to construct some real and complex valued exact solutions to the Korteweg-de Vries and modified Korteweg-de Vries equations in time fractional forms. Compatible fractional traveling wave transform plays a key role to be able to apply homogeneous balance technique to set the predicted solution. The relation between trigonometric and hyperbolic functions based on fractional Sine-Gordon equation allows to form the exact solutions with multiplication of powers of hyperbolic functions. Some exact solutions in traveling wave forms are explicitly expressed by the proposed method for both the Korteweg-de Vries and modified Korteweg-de Vries equations.

The Disembodied Eye in Maya Art and Ritual Practice
Authors: Miller Virginia E.
Published: February 2022

The ritual use and display of skulls, digits, and femurs is well documented for the Maya and other Mesoamerican groups. But except for the heart, few sources describe how organs and soft body tissues were curated during the brief time they could have been viable for manipulation or display. Nevertheless, there is rich corpus of art demonstrating that such exhibitions must have taken place. Extruded eyeballs, often with the optic nerve still attached, form part of the iconographic complex of death and the underworld, although rarely on a monumental scale during the Classic period. From the Terminal Classic on, however, images of human sacrifice and its aftermath become more prominent and public. In the northern Maya lowlands, pendant and detached eyeballs are among the motifs represented, as adornments for humans, non-humans and structures. Crania from the Sacred Cenote of Chichén Itzá show evidence of eyeball extraction, suggesting that eyeballs were removed, presumably from sacrificial victims, and manipulated post-mortem. Did the Maya adorn themselves with the eyeballs of their enemies? Throughout Mesoamerica, vision was considered a source of power, which may explain the Classic-era practice of mutilating the face, and especially the eyes, of rulers represented in Maya sculpture and painting.
Importancia relativa de los municipios de tamaño medio de la RPC

El 65 % de los municipios de la región Pacífico de Colombia, tanto en número como en la población que albergan, corresponden al rango de entre 10.000 y 50.000 habitantes; por su parte, las ciudades principales son las capitales de departamento (Quibdó, Cali, Popayán y Pasto) donde Cali se presenta como la de mayor dinámica urbana. Teniendo en cuenta el peso relativo de los municipios de tamaño medio en la RPC, se presenta un análisis geográfico que refiere los contextos de aglomeración en función de estas poblaciones (Figura 6). El concepto de aglomeración se asocia con los conceptos de economías de escala, localización y urbanización (trabajado por autores como: Christaller, 1935; Lösch, 1940; Zipf, 1949; Reilly, 1929, Hoover, 1951; Jacobs, 1969 y 1984; Fujita, et al, 1999; Henderson et al, 2000; Fujita y Thisse, 2002; Parr, 2002), donde el punto focal radica en entender cómo se establecen y qué dinámicas se generan alrededor de las concentraciones espaciales de actividades productivas. Las grandes aglomeraciones tienen como ventaja la posibilidad de tener canales de comunicación y mercados amplios para el beneficio de una población trabajadora y habitante (Isard, 1956). Los análisis referentes, enfatizan la existencia de dos variables (tamaño y distancia) que conectan entre sí la red de espacios de un territorio, por tanto, los métodos de análisis requieren usarlas (Coffey y Polèse, 1988; Polèse y Champagne, 1999; Polèse y Shearmur, 2004; Rubiera, 2006; Polèse, Rubiera y Shearmur, 2007; Aponte, 2010).

El conocimiento directo sobre los municipios permite entender las formas de valorización del capital (físico y humano: espacio cognitivo), así como las relaciones que se puedan presentar entre las características económicas, sociales, culturales, ambientales e institucionales dentro del sistema único territorial, en este caso la Región Pacífico de Colombia. Como se planteó en el capítulo anterior, el análisis de las características de la competitividad territorial se focaliza sobre los municipios que conforman el 65 % de la fuerza aglomerada de la región. Debe anotarse que la información secundaria disponible no es consistente en su totalidad, por lo que se hizo una depuración para reducir tanto el número de variables a estudiar como los municipios a revisar. De este modo se conformaron muestras (no estadísticas) de observación y, siguiendo la metodología de Torres Arzayúz y Caicedo Cuervo (2015), se perfiló un grupo de municipios que permiten dar cuenta de especificidades, pero también de rasgos que se constituyen en denominador común en este recorrido por la RPC. El trabajo realizado a partir de la información secundaria6 permitió identificar municipios que pueden ser objeto de trabajo de campo, con el fin de obtener datos primarios. No obstante, algunas limitantes (principalmente efectos de seguridad, distancia y presupuesto) determinaron la selección de algunos estudios de caso.
Deep Learning of Conjugate Mappings
Authors: Bramburger Jason
Published: February 2022

Despite many of the most common chaotic dynamical systems being continuous in time, it is through discrete time mappings that much of the understanding of chaos is formed. Henri Poincaré first made this connection by tracking consecutive iterations of the continuous flow with a lower-dimensional, transverse subspace. The mapping that iterates the dynamics through consecutive intersections of the flow with the subspace is now referred to as a Poincaré map, and it is the primary method available for interpreting and classifying chaotic dynamics. Unfortunately, in all but the simplest systems, an explicit form for such a mapping remains outstanding. In this talk I present a method of discovering explicit Poincaré mappings using deep learning to construct an invertible coordinate transformation into a conjugate representation where the dynamics are governed by a relatively simple chaotic mapping. The invertible change of variable is based on an autoencoder, which allows for dimensionality reduction, and has the advantage of classifying chaotic systems using the equivalence relation of topological conjugacies. We illustrate with low-dimensional systems such as the Rössler and Lorenz systems, while also demonstrating the utility of the method on the infinite-dimensional Kuramoto-Sivashinsky equation.
Cancer morbidity in middle and high mountain conditions of the Republic of Tajikistan

Published: February 2022

Aim. To study the prevalence of cancer diseases in the high and middle mountains of the Republic of Tajikistan.

Material and methods. The current paper studies the incidence of cancer in mountainous areas of Tajikistan covers the period between 2010-2020. We used materials from the Statistical Yearbook of the Republican Center of Medical Statistics and Information under the Ministry of Health and Social Protection of the Republic of Tajikistan (2020), statistical data from the Department of Health of GBAO, and medical and statistical data from the Central Regional Hospital in Khorog.

Result. A comparative analysis of the data for the last ten years shows that the primary incidence of cancer in Tajikistan has been increasing: the incidence rate per every 100,000 people has changed from 34.6 to 40, and in the middle and highlands from 63.1 to 85.1 cases of the disease. Between 2010 and 2020, there was a serious increase in the incidence of breast and cervical cancer among highland residents: breast cancer increased from 2.9 to 18.0 and cervical cancer from 6.8 to 13.4 cases per 100,000 population.

A field investigation was carried out at the experimental orchard of Nagpur mandarin (Citrus reticulata Blanco) at CCRI, Nagpur in block no. 44 during 2015. Breaking the seasonality of Nagpur mandarin for commercial production would not only substitute the import of fresh fruits, but also provide the incentive prices to the Nagpur mandarin growers. Withholding water, root exposure and root pruning are the common practices adopted to regulate flowering. In the recent years, chlormequat chloride and paclobutrazol, growth retardants have been used with considerable success to induce early flowering for off-season production in several fruit crops. Citrus trees are exposed to water deficit stress by withholding water for about 30-45 days before expected flowering. Many times this stress is untimely broken due to climate change related untimely rains resulting in to sparse or no flowering due loss of flowering stimulus due to untimely rains. Therefore, to assess the effectiveness of two plant growth regulators chlormequat chloride and paclobutrazol these studies were conducted. Flood irrigation was given during the stress period in second week of May and following treatments were applied to reimpose the stress broken by intermittent irrigation. Six years old trees of Nagpur mandarin were used as experimental plants. The trees were uniform in age and size and trained to single stem. The trees were grown under drip irrigation following common cultural practices during the study period. The experiment was laid out in randomized block design with seven treatments replicated four times. Four trees were used for each replication. The treatments were imposed four months before flowering (June). The treatments tried were chlormequat chloride 2000, 3000 and 4000 ppm as foliar spray, paclobutrazol 6 g, 9 g and 12 g as soil application along with control. Observations on soil moisture content (%) at weekly interval, leaf water potential (ΨL) at weekly interval, orchard microclimate: temperature, humidity and rainfall, were recorded. Paclobutrazol 12g showed the peak water stress in terms of leaf water potential (ΨL) which ranged from (-3.00 MPa to -3.17 MPa) till mid June and there was no flowering in June-July due to the high temperature (41.28°C), low rainfall (6 mm) and low humidity (40.71 %) during this period. The conditioning of microclimate in the orchard with sprinklers and irrigation can help in exploiting the flowering potential attained through growth retardant treatments.
