Dirty Waters: Urine, Waste, and the Shimmering Trans Body in Nånting måste gå sönder or Something Must Break (2014)
Authors: McKinney Casey Ann
Published: October 2023

This article examines genderqueer writer/director Ester Martin Bergsmark’s film Something Must Break (2014) and the trans gaze created through the film’s disjunctive imagery. I argue the film’s aestheticization of polluted environments and trans bodies posits a queer alliance between transness and trash. Similarly, Something Must Break’s repeated imagery of urination and body fluids representationally relates transness, waste, and transgressive sexuality to a politics of marginality, which Bergsmark employs in Something Must Break to express these relationalities as sites for creative difference and possibilities of being that exist outside of heterosexual norms. I use post-structuralist and queer interpretations of perversion to reimagine the film’s polluted environments and abject fluids as sites/sights of creation and liveability for trans bodies. I find in the refractions of polluted waters, blood, saliva, and urine in Something Must Break the same cinematic fissures that Eliza Steinbock argues allows for a uniquely trans gaze in their theory of shimmering. In considering a cinematic transgender gaze, Steinbock describes a cinema that eschews the visual reveal and instead portrays a lived trans experience not defined by dualities, but by disjunctions; thus, the unsettled, the (un)becoming, the “shimmering” aesthetics of trans embodiment. I argue Bergsmark achieves a cinematic trans gaze in their imagining of a queer space where pollution, trash, urine, and blood are not symbols of abjection and shame, but embody an opening-up, a vulnerability: a becoming that molds new forms of relationships, new forms of love, and new forms of creation.
“Passion, Salomé”: Decadent Transformations and Transgressions of Feminine Sensuality in Huysmans, Wilde, and Strauss
Authors: Diallo Mariama
Published: October 2023

Representations of Salomé have been hued in the paradoxical characterisations of the beautifully seductive and evil femme fatale. While some artists closely aligned their depictions to this Pandorian stereotype in collusion with narrative traditions of the oppressive male gaze, others challenged it through inventive reimaginations of Salomé, unveiling glimpses of the character’s complex emotive, psychological, and sensual universe that still manages to leave spectators ambivalent and discombobulated today. This article explores the transformations of Salomé in artistic representations of the Decadence across a range of media through a comparative reading of Huysmans’ novel À Rebours (1884), Wilde’s play Salomé (1891) and Strauss’ opera Salomé (1905). The interpretive changes in her characterisations – the femme fatale par excellence, the tragically fated heroine, the transgressive Decadent artist, the self-fulfilled hedonist – uncover a weaponisation of Salomé, transforming her oppressive patriarchal environmental conditions and the sexually objectifying male gaze that have often confined her, to reveal an empowered aesthetic of Decadent transgression that questions and subverts traditional gender and power dynamics, gender identities, and sensual feminine subjectivities.
Queering Sight: Visualising the Transversal Other in Josh Malerman’s Bird Box
Authors: Lim Kai Tjoon
Published: October 2023

The gaze has hitherto occupied a contentious position within theoretical discourse. While feminist and postcolonial approaches have succeeded in productively interrogating the unequal power dynamics produced by the gaze, purely naming and uncovering how these visual oppressions function do little to conceptualise possibilities of moving beyond sight’s vilification in identity formations. Unlike other physical senses such as touch and smell that have already been theorised as bases of ethical intersubjective relationality, sight has yet to be reclaimed as part of an affirmative politics to disrupt the exclusionary processes that undergird identity politics. This article is, therefore, concerned with queer interventions to rethink sight as a possible mode of transgression from restrictive binarisms within identity formation. It argues that sight instead possesses the potential to liberate bodies and constrained subjectivities from the coercive frameworks of visual objectification. By queering sight, the article positions itself as a rejection of dualistic paradigms by subversively envisioning identities as transversal processes of liberation and becoming. To this end, I will engage with Josh Malerman’s Bird Box (2014) where mediated acts of looking represent queer(ed) sources of danger and liberation. In its peculiar and particular denial of direct visual access, the novel’s aesthetics allow for productive possibilities of visualising the transversal Other.
Order and Continuity in Igor Stravinsky’s Music:
Authors: Feng Tian-Yan
Published: October 2023

The works of Igor Stravinsky (1882-1971) have been criticised for the tendency of their compositional technique towards ‘repetition,’ ‘stasis,’ ‘non-progression,’ ‘block juxtaposition,’ and even ‘discontinuity’ by musicologists and analysts including Taruskin (1996), Whittall (1997), Cross (1998), and Boulez (1968). However, more and more contemporary theorists argue that his music is not only characterised by repetition or consistency, but also that many structural phenomena and musical parameters have distinct development within the internal structure. Moreover, they point out that characteristics of both discontinuity and continuity are found at different structural levels within his compositions (Cone; Horlacher 2018; Wang 2004; Kramer 1986, 1988).

 

Taking the above scholarship into consideration, this essay analyses several musical elements to explore features of order, regularity, continuity, and consistency in the first movement of Stravinsky’s L’Histoire du Soldat, “Marche du Solda”. Closer analysis reveals that this movement exhibits many tendencies of order and consistency within individual parameters, but this order is broken when considering all parameters together, as each has its own pace and structural pattern. The analytical results presented in this essay align with the emphasis by contemporary musicologists and scholars on Stravinsky’s tendency towards consistency and order in his compositions, affirming that his music does indeed possess these features, but they require a different perspective to observe.

Published: October 2023

Abstract: Crop recommendation systems are becoming increasingly popular in agriculture due to their ability to optimize crop yield and improve efficiency. These systems rely on various factors such as soil quality, temperature, soil moisture, humidity, and pH to recommend suitable crops to grow in a particular area. The proposed project aims to develop a crop recommendation system that utilizes soil quality tests, temperature, soil moisture, humidity, and pH to recommend suitable crops to farmers. The system will use machine learning algorithms to analyze the data collected from the soil quality tests and environmental sensors to provide recommendations.

Published: October 2023

Abstract: Solar energy has proven to be an undisputed frontrunner among renewable energy sources: it is clean, environmentally responsible, and cost-effective. The utilization of solar energy as a sustainable and renewable source of power has gained significant attention in recent years. The rapid growth of solar farms and solar roofs of residential buildings has led to an increase in demand for solar modules in the global market. Therefore, the maintenance and monitoring of solar modules must rely on an effective technique for predicting and evaluating future performance. Solar hotspots, also known as solar irradiance anomalies, are areas on solar photovoltaic (PV) panels or arrays that experience excessive heating, resulting in decreased energy output and potential damage to the PV cells.

Authors: . Amul , Kumar Dr. Prashant
Published: October 2023

Abstract: Mobile communication networks have evolved from first generation to fifth generation as a result of a continuing requirement for enhancing network’s capacity to satisfy the expanding needs of customers (5G). In following years, the no. of linked devices is estimated to grow to over fifty billion, according to estimates. The heterogeneity of such a vast number of connections is expected, necessitating faster data rates, shorter latency, more system capacity, and higher throughput. Mobile networks will have to be expanded to meet up with increasing expectations. In order to meet consumers' expanding expectations and make efficient use of limited sources, D2D communication is regarded as an innovative technique for existing and future wireless networks. It permits users to connect with one another, resulting in increased energy efficiency and system throughput. This study provides a thorough examination of D2D communications, as well as the security challenges that D2D must address in order to become a viable wireless network paradigm.

Socio-Economic Impacts on the Migrants due to COVID-19
Authors: Behera Annanya
Published: October 2023

Abstract: India has a massive migrant population that accounts for 453.6 million. The migration at the state level varies from one state to another state depending on several reasons like employment availability, better living standard, marriage, education, etc. In India, it is prevalent that the flow of migration is from the state, which lacks employment opportunities for the people. This huge migrant population includes the labour migrants who mostly hail from poor backgrounds and lack formal education. These migrants work in multiple low wage works like street vending construction, stone query mines, etc. The maximum net outflow of migrants is directly from the low-income states to the high-income states. UP has the highest net outflow population, while Maharashtra occupies the highest net inflow of migrants. These migrants are the daily wage workers and constitute the informal sector. Due to the sudden outbreak, Covid-19 has impacted them the most in this pandemic. With the loss of their daily employment in the cities, these migrants started to walk back to their native villages. Also, lack of social security, social stigma, and loss of livelihood has further added to their misery. The government's initiatives at a much later stage have somehow helped them. But still, there is a long way to go before eradicating this disparity. These migrants form an indispensable part of our economy. Thus, their social and economic protection is of prime importance to us. There is a need for specific provisions and an inclusive framework for the overall security of the migrants. Access to health care, proper awareness, combating discrimination, food security, psychological support, and being connected to everyone are some of the necessary steps. Such provisions can ensure a sense of better living for these migrants.

Abstract: Modern Civilization has paved way to a number of diseases notably lifestyle diseases and Communicable diseases.As the technologies have progressed so far,man has become more inactive. Sedentary lifestyle alongwith junk foods and fermented bevarages turns more people Obese. Ayurveda is a life science which focuses not only in disease management but also in its prevention .Thus lifestyle diseases can be managed effectively through the principles of Ayurveda. Acharya Charaka has included sthula as one among the ‘Ashtaninditeeya purusha’.Acharya Vagbhata has pointed it out to be a condition arising due to excess brimhana while Madhavanidana,Yogaratnakara and Bhavaprakasa explains it under medoroga. Acharya Susruta considers sthoulya and karshya as the derangement in the circulation of rasadhatu.Thus sthoulya is covered in all its angles
O CORPO ENTRE O ENLACE DO IMPERATIVO DO SUPEREGO E O LAÇO CRIATIVO
Authors: Reis Vivian Maia , Meneses Danilo Andrade de
Published: October 2023

The objective of this work is to elucidate what body psychoanalysis is about, a body that goes beyond the biological, a body that pulsates, colonized by maternal language and the unconscious. This body establishes the beginning of psychoanalysis with a scientific inflection on medicine at the beginning of the 20th century, with formulations on hysteria. Breaking, thus, with Descartes' speech, I think, therefore, I exist. Lacan, with his return to Freud, approaches the mystery of this speaking body, taking into account the imaginary, symbolic and real registers; bringing up a body that enjoys, in search of a fantasy of completeness, facing an object that has been lost forever. In this way, it is interesting to think about cultural and contemporary ideals, to which this body that goes far beyond the biological is submitted, thus meeting the superegoic dictates of jouissance. This enjoyment can also be extracted from the creationist bias, with the sublimatory possibility of elevating the object to the dignity of the thing, this putting itself in the place of what we lack.

Deciphering the Significance of Metal Ions in the Pathogenesis of Alzheimer's Disease and Forging Pathways Towards Prospective Therapeutic Strategies
Authors: JunYi Liang , Wang Yueyang , Liu Bin , Dong Xiaohong , Cai Wenhui , Zhang Ning , Zhang Hong
Published: October 2023

Alzheimer’s disease (AD), a neurodegenerative condition, is
characterized by its progressive cognitive decline, which includes
memory impairment, language alterations, visuospatial challenges, and
compromised executive functions. The primary pathological features of AD
involve the formation of extracellular senile plaques primarily composed
of β-amyloid (Aβ) and the accumulation of hyperphosphorylated tau
proteins, leading to the creation of neurofibrillary tangles. With an
aging global population and a lack of effective AD treatments, there is
an urgent need for comprehensive AD research. Metallic elements like
iron, zinc, copper, and manganese play essential roles in human
development, metabolic pathways, and brain maturation. Accumulating
evidence suggests that these metal ions significantly influence the
development of AD, contributing to processes such as Aβ deposition,
oxidative stress, neuroinflammatory responses, and disruptions in
autophagy and apoptosis, among other cascading effects. Therefore, a
thorough investigation into the relationship between metals and AD is
crucial, not only to identify new pre-pathogenic interventions targeting
metal ions but also to support the development of tailored AD
treatments. This manuscript extensively explores the connection between
metallic elements, specifically copper, iron, zinc, and manganese, in
physiological processes and their intricate relationship with AD. It
emphasizes the importance of understanding the regulation of the metal
ion signaling network throughout the AD continuum to offer new
perspectives and potential approaches for developing innovative metal
ion modulators to combat AD. This research holds promise for addressing
the global challenge of AD.
Increasing periphyton biomass and cyanobacteria in alpine streams with retreating glaciers
Authors: Niedrist Georg , Vulcano Maria Chiara , Kainz Martin , Füreder Leopold
Published: October 2023

Deglaciation in mountain catchments changes water source contributions
and associated habitat conditions in usually cold and dynamic mountain
rivers. Although recent research has listed consequences of glacier
retreat for aquatic biodiversity, specific invertebrate and algal
groups, quantitative effects on the aquatic food web structure remain
poorly understood. In this study we assessed abiotic habitat conditions
together with the composition and the biomass of periphyton in 5
catchments in the Central European Alps over the snow-free period and
reveal significant links to declining glacier cover. We found that
reduced glaciation leads to decreasing sediment concentrations and also
to lower runoff, which in combination affects the stability of benthic
habitats. The reduced sediment load of the rivers dominates the
consequences of glacial retreat in subsequent river habitats more than
the decreasing nutrient supply. Periphyton biomass in glacier-fed rivers
is expected to increase with ongoing deglaciation and warming, which
subsequently favors particularly diatoms and cyanobacteria. This work
thus illustrates clear links between decreasing glacier cover and the
identity and relevance of aquatic producers in alpine river catchments,
and provides evidence for shifting resource base in terms of biomass
with potential consequences for its nutritional quality.
Dynamic Restoration Electricity Price Optimization Method to Enhance the Resilience of Distribution Networks with MMG
Authors: Wang Hongkun , Gao yu jie , Zhang Hong , Yan Dong Mei , Li Hongwei
Published: October 2023

Resilience is one of the main features of smart distribution network,
and a microgrid access to the distribution network provides an effective
way to improve resilience. Microgrid and distribution network belong to
different interests, so it is necessary to use price leverage to
actively guide microgrids and flexible resources within microgrid to
participate in post-disaster restoration of distribution network and
enhance the resilience. Firstly, this paper proposes a dynamic
restoration electricity price response mechanism for distribution
network after extreme disasters and constructs a power response model
for loads and electric vehicles within the microgrid. Secondly, the
optimal scheduling model of distribution network with multiple-microgrid
is proposed to improve the restoration rate of critical loads(RRCL) in
the distribution network. Single microgrid achieves the largest
microgrid revenue and restoration contribution, and multi-microgrid uses
the power headroom index to optimize the dynamic restoration electricity
price to achieve the smallest power purchase cost of distribution
network. Finally, the optimal scheduling method for resilience
enhancement of distribution networks with MMG considering dynamic
restoration electricity price response mechanism is validated by dual
microgrid access to IEEE 33-node distribution system. The simulation
results show that the proposed optimization method effectively improves
the RRCL of distribution network.
Effects of Establishing Typical Emerging Towns in Arid Oasis on Land Use Change and Regional Water Yield
Authors: Zhang Qi , He Junling , Tang Wenxi , Ju Xifeng , Saitiniyazi Adilai , Guo Xin , Zhao Wu
Published: October 2023

The urbanization process is complex and lengthy, typically bringing dual
changes in the socioeconomic structure and ecological environment.
However, facing the arid environment and the initial urbanization,
emerging towns will undergo an evolutionary process vastly different
from traditional cities. This paper takes the example of a typical town,
exploring the growth process under the overlapping background of arid
conditions and early urbanization. The results show that the initial
urbanization of towns in the hinterland of southern Xinjiang has the
following characteristics: from refined agricultural planting to shrubs
and bare land dominated by natural factors, and then to impervious
surfaces. The pattern was complex but the transition direction was
clear. Using the town establishment in 2014 as a key node, shrubland
emerged as the most sensitive land type of urbanization, with a
proportional increase of 142.8% from 2010 to 2015. During this period,
78% of shrubland was transferred from cropland. When analyzing the
annual water yield of the town and its surrounding area, it was found
that urbanization primarily manifested as increased instability in the
water yield of the surrounding region. A detailed study of emerging
urbanization in arid areas is crucial to prevent potential urban issues
in the future and promote the healthy development of small and
medium-sized towns.
Bottom-up rather than top-down mechanisms determine mesocarnivore interactions in Norway
Authors: Cano-Martínez Rocío , Thorsen Neri , Hofmeester Tim , Odden John , Linnell John , Devineau Olivier , Angoh Siow Yan Jennifer , Odden Morten
Published: October 2023

Interactions among coexisting mesocarnivores can be influenced by
different factors such as the presence of large carnivores, land-use,
environmental productivity, or human disturbance. Disentangling the
relative importance of bottom-up and top-down processes can be
challenging, but it is important for biodiversity conservation and
wildlife management. The aim of this study was to assess how the
interactions among mesocarnivores (red fox Vulpes vulpes, badger Meles
meles, and pine marten Martes martes) are affected by large carnivores
(Eurasian lynx Lynx lynx and wolf Canis lupus), land cover variables
(proportion of agricultural land and primary productivity), and human
disturbance, as well as how these top-down and bottom-up mechanisms are
influenced by season. We analyzed three years (2018-2020) of camera
trapping data from Norway and used structural equation models to assess
hypothesized networks of causal relationships. Our results show that
land cover variables are stronger predictors of mesocarnivore activity
than large carnivores in Norway. This might be caused by a combination
of low density of large carnivores in an unproductive ecosystem with
strong seasonality. Additionally, all mesocarnivores showed positive
interactions among each other, which were stronger in winter. The
prevalence of positive interactions among predators might indicate a
tendency to use the same areas and resources combined with weak
interference competition. Alternatively, it might indicate some kind of
facilitative relationship among species. Human disturbance had
contrasting effects for different species, benefiting the larger
mesocarnivores (red fox and badger) probably through food subsidization,
but negatively affecting apex predators (wolf and lynx) and smaller
mesocarnivores (pine marten). In a human-dominated world, this
highlights the importance of including anthropogenic influences in the
study of species interactions.
Cauchy problem for a loaded hyperbolic equation with the Bessel operator

This work is devoted to the study of the Cauchy problem for a
multidimensional loaded equation with the Bessel operator. When studying
problems for loaded differential equations, the properties of
Erdely-Kober operators are used as transformation operators with respect

problem for a loaded multidimensional differential equation. At the end
of the work we will show several examples on graphs.
Life history, death and taxes
Authors: Burger Joseph
Published: October 2023

The life histories of organisms and the trophic dynamics of ecosystems
are shaped by taxes paid in the form of dead offspring. No organism is
exempt from the tax because mortality is ubiquitous in the struggle of
life. New theory and data highlight how the tax: i) reflects the
proportion of the biomass produced over a life cycle that is lost to
mortality and consumed in the ecosystem, ii) is predicted by the number
and relative size of offspring, iii) varies widely across species from
<50% to >99.9%, depending on fecundity and
parental care, and iv) supplies energy and nutrition to other organisms
in the ecosystem. Taxes levied on individuals and populations support
the maintenance, infrastructure and functioning of ecosystems and human
economies alike.
Stronger carbon uptake by the ocean in eddy-resolving simulations of global warming
Authors: Couespel Damien , Lévy Marina , Bopp Laurent
Published: October 2023

Today, the ocean absorbs ~25% of the human-induced
carbon emissions. Earth System Models (ESMs) indicate that the
absorption increases by 0.79±0.07PgC per ppm of atmospheric CO2 increase
(carbon-concentration feedback), but diminishes by -17.3±5.5PgC per
degree of warming (carbon-climate feedback). Due to limited
computational capacity, ESMs parameterize flows at scales smaller than
their horizontal grid resolution, typically ~1°. We
conduct simulations of global warming using increasingly finer
horizontal resolutions (from 1° to 1/27°), with an ocean-biogeochemical
model, in an idealized mid-latitude double-gyre circulation. Our
findings demonstrate that these ocean carbon cycle feedbacks are highly
influenced by resolution. This sensitivity primarily stems from how the
overturning circulation’s mean state depends on resolution, as well as
how it responds to global warming. Although being a fraction of the
intricate response to climate change, it emphasizes the significance of
an accurate representation of small-scale ocean processes to better
constrain the future ocean carbon uptake.
Machine learning-based emulator for the physics-based simulation of auroral current system
Authors: Kataoka Ryuho , Nakamizo Aoi , Nakano Shin'ya , Fujita Shigeru
Published: October 2023

Using a machine learning technique called echo state network (ESN), we
have developed an emulator to model the physics-based global
magnetohydrodynamic (MHD) simulation results of REPPU (REProduce Plasma
Universe) code. The inputs are the solar wind time series with date and
time, and the outputs are the time series of the ionospheric auroral
current system in the form of two-dimensional (2D) patterns of
field-aligned current, potential, and conductivity. We mediated a
principal component analysis for a dimensionality reduction of the 2D
map time series. In this study, we report the latest upgraded Surrogate
Model for REPPU Auroral Ionosphere version 2 (SMRAI2) with significantly
improved resolutions in time and space (5 min in time,
~1 degrees in latitude, and 4.5 degrees in longitude),
where the dipole tilt angle is also newly added as one of the input
parameters to reproduce the seasonal dependence. The fundamental
dependencies of the steady-state potential and field-aligned current
patterns on the interplanetary magnetic field (IMF) directions are
consistent with those obtained from empirical models. Further, we show
that the ESN-based emulator can output the AE index so that we can
evaluate the performance of the dynamically changing results, comparing
with the observed AE index. Since the ESN-based emulator runs a million
times faster than the REPPU simulation, it is promising that we can
utilize the emulator for the real-time space weather forecast of the
auroral current system as well as to obtain large-number ensembles to
achieve future data assimilation-based forecast.
Quantification of delta and fluvial fan channel networks reveals distinct formative processes
Authors: Gezovich Luke Joseph , Plink-Björklund Piret , Henry Jack
Published: October 2023

Deltas and fluvial fans are two fan-shaped landforms with complex
channel networks. Deltas always occur where rivers enter a standing body
of water, such as lakes or oceans. Fluvial fans are inland terrestrial
landforms that may form thousands of kilometers from shorelines. Fluvial
fans may however also reach lakes and oceans. The current state of
knowledge lacks understanding of their morphometric differences or
recognition criteria, despite their socioeconomic significance,
vulnerability to natural hazards, and important differences in how these
landforms respond to global climate change. Moreover, numerous
fan-shaped landforms with channel networks have been identified on other
planetary bodies, such as Mars and the Saturn’s moon Titan, where deltas
are important indicators of paleo-shorelines and offer attractive
targets for mission sites due to their habitability and high
biosignature preservation potential. Here we review the known
morphometrics of delta and fluvial fan channel networks, and the
differences in their formative processes, and develop morphometric
criteria for distinguishing deltas and fluvial fans. We present an
ensemble of quantitative metrics that distinguish deltas and fluvial
fans and test these criteria on 80 modern channel networks on Earth. Our
results improve mechanistic understanding of the fluvial record and
delta evolution, provide criteria for accurate recognition of these
landforms on planetary bodies and in the sedimentary record, and explain
differences in their vulnerabilities to global change.
Spatial and Temporal Patterns in Petrogenic Organic Carbon Mobilisation during the Paleocene-Eocene Thermal Maximum

Published: October 2023

The Paleocene-Eocene Thermal Maximum (PETM) was a transient global
warming event recognised in the geologic record by a prolonged negative
carbon isotope excursion (CIE). The onset of the CIE was the result of a
rapid influx of 13C-depleted carbon into the ocean-atmosphere system.
However, the mechanisms required to sustain the negative CIE remains
unclear. Previous studies have identified enhanced mobilisation of
petrogenic organic carbon (OCpetro) and argued that this was likely
oxidised, increasing atmospheric carbon dioxide (CO2) concentrations
after the onset of the CIE. With existing evidence limited to the
mid-latitudes and subtropics, we determine whether: (i) enhanced
mobilisation and subsequent burial of OCpetro in marine sediments was a
global phenomenon; and (ii) whether it occurred throughout the PETM. To
achieve this, we utilised a lipid biomarker approach to trace and
quantify OCpetro burial in a global compilation of PETM-aged shallow
marine sites (n = 7, including five new sites). Our results confirm that
OCpetro mass accumulation rates (MARs) increased within the subtropics
and mid-latitudes during the PETM, consistent with evidence of higher
physical erosion rates and intense episodic rainfall events. The
high-latitude sites do not exhibit distinct changes in the organic
carbon source during the PETM. This may be due to the more stable
hydrological regime and/or additional controls. Crucially, we also
demonstrate that OCpetro MARs remained elevated during the recovery
phase of the PETM. Although OCpetro oxidation was likely an important
positive feedback mechanism throughout the PETM, we show that this
feedback was both spatially and temporally variable.
Controls on Bending-Related Faulting Offshore of the Alaska Peninsula

Published: October 2023

Oceanic plates experience extensive normal faulting as they bend and
subduct, enabling fracturing of the crust and upper mantle. Debate
remains about the relative importance of pre-existing faults, plate
curvature and other factors in controlling the extent and style of
bending-related faulting. The subduction zone off the Alaska Peninsula
is an ideal place to investigate controls on bending-related faulting as
the orientation of abyssal-hill fabric with respect to the trench and
plate curvature vary along the margin. Here we characterize bending
faulting between longitudes 161°W and 155ºW using newly collected
multibeam bathymetry data. We also use a compilation of seismic
reflection data to constrain patterns of sediment thickness on the
incoming plate. Although sediment thickness increases by over 1 km from
156°W to 160°W, most sediments were deposited prior to the onset of
bending faulting and thus have limited impact on the expression of
bend-related fault strikes and throws in bathymetry data. Where magnetic
anomalies trend subparallel to the trench (<30°) west of
~156ºW, bending faulting parallels magnetic anomalies,
implying bending faulting reactivates pre-existing structures. Where
magnetic anomalies are highly oblique (>30°) to the trench
east of 156ºW, no bending faulting is observed. Summed fault throws
increase to the west, including where pre-existing structure
orientations do not vary between 157-161ºW, suggesting that the increase
in slab curvature directly influences fault throws. However, the
westward increase in summed fault throws is more abrupt than expected
for changes in slab bending alone, suggesting potential feedbacks
between pre-existing structures, slab dip, and faulting.
Discriminating lithospheric and asthenospheric anisotropy beneath Northern Oman: sharp contrast observed at the Semail Gap Fault Zone
Authors: Komeazi Abolfazl , Kaviani Ayoub , Rümpker Georg , Weidle Christian , Meier Thomas
Published: October 2023

To gain a deeper understanding of the extensive and varied lithospheric
deformations beneath northern Oman, we examine seismic anisotropy in
this region using splitting analysis of teleseismic shear wave data. Our
study utilizes data from a dense network consisting of 13 permanent and
45 temporary seismic stations, which were operational for approximately
2.5 years starting from 2013. By examining the azimuthal distribution of
shear wave splitting (SWS) parameters, we are able to divide the study
area into three sub-regions. The stations located to the west of the
Hawasina window exhibit relatively azimuthally invariant SWS parameters
suggesting a single anisotropic layer. On the other hand, most of the
stations located in the central and eastern regions display a 90-degree
periodicity versus back-azimuth, indicating the presence of
depth-dependent anisotropy.

The General NW-SE trend of the Fast Polarization Directions (FPDs),
one-layer/upper layer FPDs in the east and one-layer FPDs in the west,
is concordant with the strike of the structures resulting from the
collision between the continental and oceanic plates. Notably, a
distinct contrast in the SWS parameters is observed at Semail Gap Fault
Zone (SGFZ), suggesting that the SGFZ can be a geological border for the

The influence of climate feedbacks on regional hydrological changes
under warming is poorly understood. Here, a moist energy balance model
(MEBM) with a Hadley Cell parameterization is used to isolate the
influence of climate feedbacks on changes in zonal-mean
precipitation-minus-evaporation (P-E) under greenhouse-gas forcing. It
is shown that cloud feedbacks act to narrow bands of tropical P-E and
increase P-E in the deep tropics. The surface-albedo feedback shifts the
location of maximum tropical P-E and increases P-E in the polar regions.
The intermodel spread in the P-E changes associated with feedbacks
arises mainly from cloud feedbacks, with the lapse-rate and
surface-albedo feedbacks playing important roles in the polar regions.
The P-E change associated with cloud feedback locking in the MEBM is
similar to that of a climate model with inactive cloud feedbacks. This
work highlights the unique role that climate feedbacks play in causing
deviations from the “wet-gets-wetter, dry-gets-drier” paradigm.

Early peopling of Brazil’s Northeast region (BRN) took place under an
intimate relationship between humans and water scarcity, as the region,
especially the state of Ceará (CE), has dealt historically with severe
drought events since the 1800’s, which commonly led to catastrophic
impacts of mass migration and deaths of thousands of people. Throughout
the last century, the so-called “Droughts Polygon” region experienced
intense infrastructural development, with the expansion of a dense
network of reservoirs. This resulted in the evolution of a complex
hydrologic system requiring a holistic investigation in terms of its
hydrologic tradeoffs. This paper presents a parsimonious hydrologic
modeling approach to investigate the 100-year (1920-2020) evolution of a
dense surface-water network in the 24,500 km² Upper Jaguaribe Basin,
with the ultimate goal of generating insights into the coevolution of a
tightly coupled human-water system. Our model is driven by both climatic
and human inputs, while model structure is allowed to evolve over time
to dynamically mimic evolution of population size, reservoir count and
water demand. Hundred years of continuous growth in storage capacity
experienced within the UJ Basin is found to reflect the transition from
complete vulnerability to droughts to achievement of significantly
increased levels of water security. However, drought severity had in the
meantime disproportionally intensified in this period, especially in
reservoirs of medium to small capacities. Our analysis results have
generated valuable insights into the different roles that reservoir
expansion has played in securing the stability of human settlement
patterns in drought prone regions.
Assessment of the Madden-Julian Oscillation in CMIP6 Models based on Moisture Mode Theory

Published: October 2023

The moist processes of the Madden-Julian Oscillation (MJO) in the
Coupled Model Intercomparison Project Phase 6 models are assessed using
moisture mode theory-based diagnostics over the Indian Ocean (10°S-10°N,
75°E-100°E). Results show that no model can capture all the moisture
mode properties relative to the reanalysis. Most models satisfy weak
temperature gradient balance but have unrealistically fast MJO
propagation and a lower moisture-precipitation correlation. Models that
satisfy the most moisture mode criteria reliably simulate the background
moist static energy (MSE) and low-level zonal winds compared to models
that satisfy the least amount of criteria. The MSE budget associated
with the MJO is also well-represented in the good models rather than in
the poor models. Our results show that capturing the MJO’s moisture mode
properties over the Indian Ocean is associated with a more realistic
representation of the MJO simulation and thus can be employed to
diagnose MJO performance.
Probing the nature of low-frequency earthquakes through the deconvolution of tectonic tremor
Authors: Song Chao , Rubin Allan M
Published: October 2023

Currently there are two end-member views of low-frequency earthquakes
(LFEs). One is that they result from stick-slip behavior of Mxed brittle
patches that are mechanically distinct from the surrounding, creeping,
fault. The other is that they represent the high-frequency limit of
stochastic accelerations and decelerations of slip on the fault, with
boundaries that may vary with time. Among the many unknowns concerning
LFEs are their physical dimensions, knowledge of which might place
constraints on their underlying nature.

Estimates of LFE source sizes range from 100 m (if they have a stress
drop similar to regular earthquakes) to more than 1 km (if they rupture
at local shear wave speeds, given a ~0.5-s duration).
Our 4-s tremor catalogs have an estimated location uncertainty smaller
than 1 km, and many consecutive and nearly consecutive detections are
spaced closer than this. This suggests that if LFEs are close to the
upper size limit, successive events are strongly overlapping, which
seems more consistent with the stochastic acceleration and deceleration
model of LFE generation. Moreover, many 4-s windows themselves contain
multiple nearly co- located LFE-like arrivals. This encourages us to use
LFE templates to deconvolve tremor seismograms, to obtain an LFE catalog
with a temporal resolution conceivably as high as one event per LFE
duration. Our preliminary catalog shows that many LFEs as close in time
as 0.5 s are separated by less than 1 km. Figure 1 shows LFE detections
from a 250-s window with an overall 2-km migration to the southeast. The
median event has 75 other detections within 1 km. In the propagation
direction, also the direction of low error, the median separation
between consecutive events is 360 m. If LFEs are km-scale, possible
explanations for the signiPcant overlap between events sometimes as
close as 0.5 s in time (see the zoom) include reQected waves from
boundaries of a low-velocity shear zone, or inertial vibrations at low
normal stress (Im and Avouac, 2021). If, instead, LFEs are brittle
asperities closer to 100 m in size, successive events need not overlap,
but one must explain both their long duration and why, with so many
sources in close proximity, nearly none are observed to grow larger in
both duration and magnitude than is characteristic of LFEs.
A model-based investigation of the recent rebound of shelf water salinity in the Ross Sea
Authors: ZHANG Jingwei , Zhang Xuebin , King Matt A , Lyu Kewei
Published: October 2023

Intense atmosphere-ocean-ice interactions in the Ross Sea play a vital
role in global overturning circulation by supplying saline and dense
shelf waters. Since the 1960s, freshening of the Ross Sea shelf water
has led to a decline in Antarctic Bottom Water formation. Since the
early 2010s, however, the salinity of the western Ross Sea has
rebounded. This study adopts an ocean-sea ice model to investigate the
causes of this salinity rebound. Model-based salinity budget analysis
indicates that the salinity rebound was driven by increased brine
rejection from sea ice formation, triggered by the nearly equal effects
of local anomalous winds and surface heat flux. The local divergent wind
anomalies promoted local sea ice formation by creating a thin ice area,
while a cooling heat flux anomaly decreased the surface temperature,
increasing sea ice production. This highlights the importance of
understanding local climate variability in projecting future dense shelf
water change.
Does increasing horizontal resolution improve the simulation of intense tropical rainfall?
Authors: Nikumbh Akshaya C , Lin Pu , Paynter David , Ming Yi
Published: October 2023

We examine tropical rainfall from Geophysical Fluid Dynamics
Laboratory’s Atmosphere Model version 4 (GFDL AM4) at three horizontal
resolutions of 100 km, 50 km, and 25 km. The model produces more intense
rainfall at finer resolutions, but a large discrepancy still exists
between the simulated and the observed frequency distribution. We use a
theoretical precipitation scaling diagnostic to examine the frequency
distribution of the simulated rainfall. The scaling accurately produces
the frequency distribution at moderate-to-high intensity (≥10 mm day-1).
Intense tropical rainfall at finer resolutions is produced primarily
from the increased contribution of resolved precipitation and enhanced
updrafts. The model becomes more sensitive to the grid-scale updrafts
than local thermodynamics at high rain rates as the contribution from
the resolved precipitation increases. On the contrary, the observed
tropical precipitation extremes do not show a strong sensitivity to the
grid-scale updrafts.
Modulation of Tropical Convection-circulation Interaction by Aerosol Indirect Effects in Idealized Simulations of a Global Convection-permitting Model
Authors: Su Chun-Yian , Wu Chien-Ming , Chen Wei-Ting , Peters John
Published: October 2023

Observations suggest tropical convection intensifies when aerosol
concentrations enhance, but quantitative estimations of this effect
remain highly uncertain. Leading theories for explaining the influence
of aerosol concentrations on tropical convection are based on the
dynamical response of convection to changes in cloud microphysics,
neglecting possible changes in the environment. In recent years, global
convection-permitting models (GCPM) have been developed to circumvent
problems arising from imposing artificial scale separation on physical
processes associated with deep convection. Here, we use a GCPM to
investigate how enhanced concentrations of aerosols that act as cloud
condensate nuclei (CCN) impact tropical convection features by
modulating the convection-circulation interaction. Results from a pair
of idealized non-rotating radiative-convective equilibrium simulations
show that the enhanced CCN concentration leads to weaker large-scale
circulation, the closeness of deep convective systems to the moist
cluster edges, and more mid-level cloud water at an equilibrium state in
which convective self-aggregation occurred. Correspondingly, the
enhanced CCN concentration modulates how the diabatic processes that
support or oppose convective aggregation maintain the aggregated state
at equilibrium. Overall, the enhanced CCN concentration facilitates the
development of deep convection in a drier environment but reduces the
large-scale instability and the convection intensity. Our results
emphasize the importance of allowing atmospheric phenomena to evolve
continuously across spatial and temporal scales in simulations when
investigating the response of tropical convection to changes in cloud
microphysics.
