Giant Splenomegaly Secondary to Chronic Myeloid Leukemia: Case Report
Authors:   Facultad de Estudios Superiores Iztacala de la Universidad Nacional Autónoma de México. Ciudad de México, México., Alejandra Jacuinde Villalobos Beatriz
Published: November 2022

The abnormal growth of the spleen is called splenomegaly, this finding is a challenge when determining its etiology for the first contact physician due to the wide range of diagnostic possibilities. Infectious, tumoral, and hematologic aetiologies should always be sought among the main aetiologies. In this case, we present a 45-year-old male patient who came to the clinic for the first time because he presented with a palpable and non-painful abdominal tumor of long evolution, with a diagnosis of chronic myeloid leukemia for 6 years, with poor adherence to treatment. Its diagnosis is based on obtaining images through methods such as tomography or magnetic resonance imaging to confirm the presence of splenomegaly, but ultrasound remains the technique of choice in Primary Care. Through clinical suspicion and performing an ultrasound in consultation, we arrive at a clinical diagnosis
Effect of Rasayan Therapy in Post-Menopausal Geriatric Females: A Holistic and Conceptual Approach
Authors:   PG scholar, Government Ayurveda College and Hospital, Chaukaghat Varanasi, Uttar Pradesh ,India, Kalia Dr. Bharti
Published: November 2022

Menopause is just puberty’s evil sister. Geriatric women are passing through various physiological changes of body like premenopausal symptoms, perimenopause and post menopause. Menopause is a normal physiologic process in ageing women. Although many women over age 65 have persistent menopausal symptoms, there are limited data to guide therapy among older women. Approximately 9-16% of women over the age of 65 continue to have menopausal symptoms and 13.7% of those women are using some form of menopausal hormone therapy (HT). In geriatric age cognitive disturbance, urinary symptoms, vasomotor symptoms, psychogenic symptoms, sexual dysfunction, mood changes etc. have been linked to hormonal changes and increasing age among females. These changes are generally due to disturbed Vata dosha and Dhatukhaya. In geriatric women it is better to balance aggravated doshas so that the intensity of these diseases will be far less. This can be restrained with the unique therapeutic method known as Rasayana chikitsa which minimize the intensity of problems occurring during this phase of life. The focus of the article is to describe the pathophysiologic symptoms related to menopausal transition and to review the effect of rasayana therapy in geriatric women with special care of menopausal symptoms. If implemented properly Rasayana can give a better result instead of hormonal replacement therapy.

Published: November 2022

The aims of this work were to evaluate the synergistic antioxidant activity and optimize microwave-assisted extraction of Caesalpinia sappan L., Hibiscus sabdariffa L., and Clitoria ternatea L. combinations. The simplex lattice design was applied to evaluate the synergistic antioxidant activity. The mass ratios of the 3 plants that exhibited synergistic antioxidant activity were further used to investigate the optimal condition of microwave-assisted extraction by Box-Behnken design. Results showed that the synergistic antioxidant activity among the 3 plants: Which was determined by the combination index, was observed at various mass ratios, especially at the equal mass ratio. The optimal microwave-assisted extraction condition providing the best antioxidant activity of the plant extract was microwave power of 300 W for 30 s and 3 cycles. This condition gave the extraction yield of 31.03 ± 0.26 %, total phenolic content of 72.03 ± 3.83 mg GAE/g extract, total flavonoid content of 15.18 ± 0.42 mg CE/g extract, half-maximal inhibitory concentration (IC50) from DPPH assay of 178.16 ± 15.54 µg/mL and IC50 from FRAP assay of 75.26 ± 4.44 µg/mL. The optimal extract showed no toxicity on HepG2 cells although the tested concentration was up to 1 mg/mL with an IC50 value of 5.45 mg/mL. So, a mixture of the 3 colored plants could be used as a supplementary antioxidant product with a safety profile.

Authors: Bono Géraldine L. P. , Achermann Prisca , Rückriem Bärbel , Lieber Jan , van Hedel Hubertus J. A.
Published: November 2022

Importance: Children with hemiparesis experience limitations in activities of daily living (ADLs) as a result of upper limb impairments. To address these limitations, we developed a group-based Personalized Upper Limb Intensive Therapy (PULIT) program combining modified constraint-induced movement therapy, bimanual intensive therapy, and exergame-based robotics.

Objective: To determine the effectiveness of PULIT in helping children with upper limb impairments achieve individually set goals and enable transfer of the attained motor skills into ADLs.

Design: Retrospective analysis.

Setting: Day camp at a pediatric rehabilitation clinic in Switzerland.

Participants: Twenty-three children with upper limb impairment (unilateral cerebral palsy, n = 16; acquired brain injury, n = 7); 13 boys and 10 girls (M age = 7 yr, 8 mo, SD = 2 yr, 1 mo; Manual Ability Classification System Level I–IV).

Intervention: Thirty hours of PULIT over the course of 8 days.

Outcomes and Measures: Goal attainment scaling (GAS) was assessed on the first and last day of intervention. The Canadian Occupational Performance Measure (COPM) and dexterity tests, such as the Box and Block Test (BBT), were administered 3 wk before and 3 wk after the intervention.

Results: Total goal achievement was 85.7%. GAS, parent- and child-rated COPM Performance and Satisfaction, and the BBT of the affected and dominant upper limb improved significantly.

Conclusions and Relevance: PULIT effectively increases children’s dexterity of the impaired and dominant upper limb, improves ADL performance, and achieves individual goals. This retrospective analysis could serve as a basis for a future randomized trial.

What This Article Adds: This article informs occupational therapy practitioners about a therapy program that includes conventional and rehabilitation technology interventions and enables children with hemiparesis of the upper limb to improve relevant ADL tasks in 8 days’ time.
Coprodução de serviços públicos e participação social: o efeito do decreto nº 9.759/2019 na vigência dos conselhos gestores brasileiros
Authors: Almeida Thiago Chagas de , Emmendoerfer Magnus Luiz
Published: November 2022

Este trabalho parte da discussão dos efeitos do Decreto nº 9.759/2019 nos mecanismos de participação social brasileiros. Seu objetivo foi de verificar, especificamente, como esse ato normativo pode ter impactado no período de vigência dos conselhos gestores de políticas públicas e consequentemente, alterado os momentos de interação entre o Estado e os cidadãos para a coprodução de serviços públicos. Para tanto, foi realizado um teste t de médias independentes e um teste qui-quadrado de homogeneidade, comparando a vigência dos conselhos antes e depois do referido Decreto. Os resultados da pesquisa indicaram que o período de vigência dos conselhos antes do Decreto foi significativamente maior que depois dele. Isso revela que as normas e a representação simbólica de uma legislação podem restringir a instituição dos colegiados de participação social e dificultar a coprodução de serviços públicos. Desse modo, este trabalho contribui para preencher a lacuna teórica de compreender os fatores que desmobilizam a coprodução. Além disso, os resultados desta pesquisa amparam posicionamentos que queiram reformular o Decreto nº 9.759/2019, a fim de ampliar os momentos de diálogo entre o governo e a sociedade e assim, favorecer a coprodução e a democracia participativa.
Abordaje clínico de la estimulación facial en implantes cocleares
Authors: Rosanigo Gabriel , Del Vecchio Verónica , Ausili Sebastian
Published: November 2022

El implante coclear es actualmente uno de los dispositivos de rehabilitación neurosensoriales más exitosos. El mismo brinda la posibilidad de escuchar en personas con hipoacusias severas a profundas que obtienen limitado acceso a los sonidos con amplificación acústica. Sin embargo, existen complicaciones luego de su implantación, entre las cuales se encuentra la estimulación indeseada del nervio facial. Entre los principales detrimentos que produce la estimulación del nervio facial se encuentran los movimientos involuntarios de cara o cuello, molestia o dolor al usar el implante, entre otros. En algunos casos esto sucede sólo en algunos contactos, pero también puede presentarse en la mayoría o incluso todos los canales de estimulación.

El actual abordaje clínico de este problema recurre principalmente a diferentes cambios en la programación del dispositivo. Los recursos para reducirlo abarcan desde cambios en el tipo y modo de la estimulación eléctrica, hasta considerar la reimplantación en casos complejos. El presente artículo describe el problema de la estimulación facial y sus posibles causas, como así también detalla las soluciones clínicas que existen en la actualidad. Por último, se discuten nuevos abordajes y potenciales líneas de investigación.
An Elusive Happy Ending: The Complexities of Indian Courtesan Films
Authors:   Asia Social Science Academy, Li Huming
Published: November 2022

This paper examines the complexities of characters, narratives and aesthetics in the Indian courtesan film genre by analyzing three classic courtesan films: Pakeezah (dir. Kamal Amrohi, 1972), Umrao Jaan (dir. Muzaffar Ali, 1981), and its more recent remake Umrao Jaan (dir. J.P. Dutta, 2006). First, from the perspective of screen characters, the paper summarizes the necessary condition for a courtesan character to achieve a happy ending—the marriage between the heroine and the hero, and then illustrates the decisive factors and difficult process to fulfill this condition. Then, from the perspective of audiences, this paper explains the elusiveness of happy endings in courtesan films by analyzing the multiple relationships between audiences and screen characters and the differences within audiences. The paper also attempts to provide a glimpse of the Muslim nawabi culture, in which courtesan films are rooted, in order to help the readers to appreciate the cultural significance and myriad appeals of this distinctive subgenre of Indian cinema and Indian film art in general.
La narration iconotextuelle au service de l’activité de création. Dispositif didactique et démarche sémiotique pour rendre l’élève cré-acteur·rice de ses apprentissages.
Authors: Lebreton Maud , Attanasio Rachel
Published: November 2022

Cette recherche a été menée dans trois classes du cycle 1 dans le canton de Vaud en Suisse. Basée sur le processus créatif de Wallas (2003) et les facteurs identifiés de la créativité (Lubart, 2003), elle propose d'inscrire la posture de créateur·rice dans une perspective sémiotique sociale en employant la narration multimodale de l’album comme objet médiateur.  Support pédagogique de choix, notamment en raison de la richesse de l'offre, la dimension affective des images et de la narration, l'album est un objet composite dont la complexité sémiotique contraint à un processus de fabrication de sens métaphorique qualifié de hautement créatif (Kress, 2010). Comme la motivation du fabricant de signes dépend de ses intérêts (Kress, 2010), la participation à une trame narrative qui doit trouver son dénouement place l'élève en position de cré-acteur·rice de son apprentissage. Le média multimodal sert ici de matériau de (re)conceptualisation dans lequel la transmédiation (Suhor, 1984, cité dans Sullivan, 2017) est mise au service de la posture de créateur·rice. L'objet produit peut alors prendre un rôle actif dans la construction de sens (Bowker & Star, 2000), faisant du processus une pratique transformatrice (Conne, 2008) pour l'apprenant·e. Renvoyant à la sémiotique sociale, l'apprentissage est ici envisagé avant tout comme un processus de création de sens située (Budach, 2018 ; Mottier Lopez, 2016) dans une perspective anthropologique de l’éducation (Ingold, 2018).
Portrait de quatre espaces créatifs au Québec : analyse à partir de la théorie de l’activité

Published: November 2022

Les espaces créatifs permettent aux utilisateurs de fabriquer, de transformer et de s’équiper, ainsi que de participer, de partager et d’apprendre. Ces actions soutiennent l’effet de démocratisation du mouvement maker (Hatch, 2014) ainsi que le développement du pouvoir d’agir rendu possible dans les espaces créatifs (Blikstein, 2013 ; Davidson et Duponsel, 2021). Cet article présente l’analyse de quatre espaces créatifs au Québec et permet de relever les caractéristiques de ces espaces d’apprentissage non formels. Le regard porté sur les espaces créatifs a été guidé par la théorie de l’activité (Engeström, 1987). Différents aspects (sujet, outil, objet, division du travail, règles et communauté) ont été analysés à partir des transcriptions d’entretiens semi-dirigés, menés auprès des responsables d’espaces créatifs et des utilisateurs. L’analyse soutenue par la théorie de l’activité permet d’aborder de façon systémique l’organisation des activités dans des espaces créatifs non formels. Notre projet revêt un intérêt pour l’avancement des connaissances, car il permet de relever des tensions liées à la notoriété, à l’équipement, à l’apprentissage et la communauté, qui pourraient être présentes dans d’autres espaces créatifs.

A Focus Group Study Exploring Perceptions of Online Hookup App Use Among Heterosexual Women
Authors:   Bowling Green State University, Maziarz Lauren
Published: November 2022

Online dating platforms have become a more common way for adults in the United States (U.S.) to find both romantic partners as well as sex partners. While certain hookup apps, such as Grindr, market towards men who have sex with men (MSM), other platforms, like Tinder, tend to attract people who identify as heterosexual. Eighteen self-identified heterosexual college women participated in one of four focus groups between April and October 2019. Focus groups were audio recorded and transcribed by the research team and themes were analyzed after all focus groups were complete. Four salient themes emerged which included concerns about meeting in person for the first time, apps making it easier to find partners, apps promoting hookup culture, and differences in perception depending on which gender you identify as. There are perceived advantages to using apps to find a partner but also hesitation. Future research should focus on the extent to which heterosexual women are using hookup apps to find sex partners and how these apps affect the sexual health and mental wellbeing of self-identified heterosexual women.
Bitcoin Investment Strategies Based on Google Trends and AI Models
Authors: Gómez Martínez Raúl , Martínez Navalón Juan Gabriel , Prado Román Camilo
Published: November 2022

The evolution of the price of bitcoin has captured the attention of analysts in recent years. But how can a cryptocurrency be valued? Given that the price is linked to expectations, we propose, in this paper, to predict the trend of bitcoin using Google Trends as an explanatory variable. To do so, we develop two alternative algorithmic trading systems that buy or sell bitcoin depending on whether the searches for this term in Google increase or decrease. The approach is powered using artificial intelligence. The results of these trading systems are positive and show that trading strategies can be implemented based on investors’ mood about an asset, in this case measured through Google Trends. The use of artificial intelligence in trading is new and this is an example of its potential.
Monitoring multiple satellite aerosol optical depth (AOD) products within the Copernicus Atmosphere Monitoring Service (CAMS) data assimilation system

Abstract. The Copernicus Atmosphere Monitoring Service (CAMS)
provides near-real-time forecast and reanalysis of aerosols using the ECMWF
Integrated Forecasting System with atmospheric composition extension,
constrained by the assimilation of MODIS and the Polar Multi-Sensor Aerosol
Optical Properties (PMAp) aerosol optical depth (AOD). The objective of this
work is to evaluate two new near-real-time AOD products to prepare for their
assimilation into CAMS, namely the Copernicus AOD (collection 1) from the Sea
and Land Surface Temperature Radiometer (SLSTR) on board Sentinel 3-A/B
over ocean and the NOAA EPS AOD (v2.r1) from VIIRS on board S-NPP and
NOAA20 over both land and ocean. The differences between MODIS (C6.1), PMAp
(v2.1), VIIRS (v2.r1), and SLSTR (C1) AOD as well as their departure from the
modeled AOD were assessed at the model grid resolution (i.e., level-3)
using the 3-month AOD average (December 2019–February 2020 and March–May 2020). VIIRS and MODIS show the best consistency across the products, which is
explained by instrument and retrieval algorithm similarities. VIIRS AOD is
frequently lower over the ocean background and higher over biomass burning
and dust source land regions compared to MODIS. VIIRS shows larger spatial
coverage over land and resolves finer spatial structures such as the
transport of Australian biomass burning smoke over the Pacific, which can be
explained by the use of a heavy aerosol detection test in the retrieval
algorithm. Our results confirm the positive offset over ocean (i) between
Terra/MODIS and Aqua/MODIS due to the non-corrected radiometric calibration
degradation of Terra/MODIS in the Dark Target algorithm and (ii) between
SNPP/VIIRS and NOAA20/VIIRS due to the positive bias in the solar reflective
bands of SNPP/VIIRS. SLSTR AOD shows much smaller level-3 values than the
rest of the products, which is mainly related to differences in spatial
representativity at the IFS grid spatial resolution due to the stringent
cloud filtering applied to the SLSTR radiances. Finally, the geometry
characteristics of the instrument, which drive the range of scattering
angles sampled by the instrument, can explain a large part of the
differences between retrievals such as the positive offset between PMAp datasets from MetOp-B and MetOp-A.
Measurement report: Contrasting elevation-dependent light absorption by black and brown carbon: lessons from in situ measurements from the highly polluted Sichuan Basin to the pristine Tibetan Plateau
Authors: Zhao Suping , Qi Shaofeng , Yu Ye , Kang Shichang , Dong Longxiang , Chen Jinbei , Yin Daiying
Published: November 2022

Abstract. Scientific knowledge about light absorption by aerosols is
extremely limited at the eastern slope of the Tibetan Plateau (ESTP). We
conducted the first aerosol field experiment at six sites (Chengdu,
Sanbacun, Wenchuan, Lixian, Maerkang, Hongyuan) along the ESTP, ranging in
elevation from 500 to 3500 m. The fraction of light absorption by brown
carbon (BrC) to total carbon increases from 20 % to 50 % with altitude,
and the mass absorption efficiency (MAE) of BrC over the Tibetan Plateau (TP) is 2–3 times
higher than that inside the Sichuan Basin (SCB), especially in winter. In
contrast, the MAE of elemental carbon (EC) in winter decreases with
altitude. The contrasting variation of EC and BrC MAE with altitude is
mainly attributed to source differences between the TP and SCB. Emissions
from the more urban sources (motor vehicles, industries, etc.) inside the
SCB fail to be transported to the TP due to the stable air in winter inside
the basin, which is also favourable for aerosol ageing to enhance absorption
efficiency. The radiative forcing of BrC relative to EC varies from 0.10 to
0.42 as altitude increases with the higher organic carbon (OC) to EC ratio over the TP than SCB.
Thus, the reason for the enhanced relative BrC to EC radiative forcing from
polluted SCB to pristine TP is that the BrC concentration decreases more
slowly than the EC concentration with altitude. This study contributes to
the understanding of the difference in light absorption by EC and BrC with
altitude, from polluted lower-altitude basins to the pristine TP, and
provides a data set for regional climate model validation.
Radio frequency interference detection and mitigation in the DWD C-band weather radar network
Authors: Schaper Maximilian , Frech Michael , Michaelis David , Hald Cornelius , Rohrdantz Benjamin
Published: November 2022

Abstract. C-band weather radar data are commonly compromised by interference from external sources even though weather radars are the primary and therefore
privileged user of this frequency band. This is also the case for the radar network of the German Meteorological Service (Deutscher Wetterdienst, DWD). Theoretically, dynamic frequency selection (DFS) by devices operating in the C band should prevent any disturbance of the primary user. In practice, this does not always work as intended under the current regulations. As it is not possible to separate a superimposed interference signal from measured weather radar data, the protection of the frequency band is of utmost importance. Currently, the only available option is to discard the compromised portions of the radar data. Therefore, the current best course of action is to shut down radio frequency interference (RFI) sources as quickly as possible. The automated RFI detection algorithm for the German C-band weather radar network, operational since July 2017, makes use of
routinely measured radar moments. Built upon data gathered since 2017, an RFI classification with respect to the severity and duration of RFI sources was first implemented in 2019. An independent verification of the RFI detection algorithm was performed by using a commercially available Wi-Fi adapter, which is directly integrated into the radar receiver. Subsequently, a mitigation workflow was implemented to efficiently identify and shut down detected RFI sources by the German Federal Network Agency (Bundesnetzagentur, BNetzA). By following this workflow with great effort, the number of persistent RFI sources has been decreasing since October 2019, while a steady increase in short-lived RFI sources over the last 5 years also exists. In total, 11 889 RFI sources have been identified from July 2017 to May 2022. Most of these (94.8 %) are such short-lived sources that an
unambiguous identification by the BNetzA is, in general, not feasible. However, as stated by the C-band regulations, any non-compliant transmitter compromising the operation of a weather radar has to be shut down. This is important, as even these short-lived RFI sources negatively affect meteorological product generation.
South Asian summer monsoon enhanced by the uplift of Iranian Plateau in Middle Miocene
Authors: Zuo Meng , Sun Yong , Zhao Yan , Ramstein Gilles , Ding Lin , Zhou Tianjun
Published: November 2022

Abstract. The South Asian summer monsoon (SASM) remarkably strengthened during the Middle Miocene (16–11 Ma), coincident with the rapid uplifts of the Iranian Plateau (IP) and the Himalaya (HM). Although the development of the SASM has long been linked to the topographic changes in the Tibetan Plateau (TP) region, the effects of the HM and IP uplift are still vigorously debated, and the underlying mechanisms remain unclear. Based on Middle Miocene paleogeography, we employ the fully coupled earth system model CESM to perform a set of topographic sensitivity experiments with altered altitudes of the IP and the HM. Our simulations reproduce the strengthening of the SASM in northwestern India and over the Arabian Sea, largely attributing to the thermal effect of the IP uplift. The elevated IP insulates the warm and moist airs from the westerlies in the south of the IP and produces a low-level cyclonic circulation around the IP, which leads to the convergence of the warm and moist air in the northwestern India and triggers positive feedback between the moist convection and the large-scale monsoon circulation, further enhancing the monsoonal precipitation. Whereas the HM uplift produces orographic precipitation without favorable circulation adjustment for the SASM. We thus interpret the intensification of the Middle Miocene SASM in the western part of the South Asia as a response to the IP uplift while the subtle SASM change in eastern India reflects the effects of the HM uplift.
Tin weathering experiment set by nature for 300 years: natural crystals of the anthropogenic mineral hydroromarchite from Creussen, Bavaria, Germany

corrosion of pewter artefacts. Here we report a new locality for this rare
mineral found at the Saint James Church archaeological site in Creussen,
Germany. There it appeared to be a product of weathering of a tin artefact

mineral, found in paragenesis with romarchite and cassiterite, was
identified using single-crystal X-ray diffraction.
A local particle filter and its Gaussian mixture extension implemented with minor modifications to the LETKF
Authors: Kotsuki Shunji , Miyoshi Takemasa , Kondo Keiichi , Potthast Roland
Published: November 2022

Abstract. A particle filter (PF) is an ensemble data assimilation
method that does not assume Gaussian error distributions. Recent studies
proposed local PFs (LPFs), which use localization, as in the ensemble Kalman
filter, to apply the PF efficiently for high-dimensional dynamics. Among
others, Penny and Miyoshi (2016) developed an LPF in the form of the ensemble
transform matrix of the local ensemble transform Kalman filter (LETKF). The
LETKF has been widely accepted for various geophysical systems, including
numerical weather prediction (NWP) models. Therefore, implementing the LPF
consistently with an existing LETKF code is useful. This study develops a software platform for the LPF and its Gaussian mixture
extension (LPFGM) by making slight modifications to the LETKF code with a
simplified global climate model known as Simplified Parameterizations,
Primitive Equation Dynamics (SPEEDY). A series of idealized twin experiments
were accomplished under the ideal-model assumption. With large inflation by
the relaxation to prior spread, the LPF showed stable filter performance
with dense observations but became unstable with sparse observations. The
LPFGM showed a more accurate and stable performance than the LPF with both
dense and sparse observations. In addition to the relaxation parameter,
regulating the resampling frequency and the amplitude of Gaussian kernels
was important for the LPFGM. With a spatially inhomogeneous observing
network, the LPFGM was superior to the LETKF in sparsely observed regions,
where the background ensemble spread and non-Gaussianity were larger. The
SPEEDY-based LETKF, LPF, and LPFGM systems are available as open-source
software on GitHub (https://github.com/skotsuki/speedy-lpf, last access: 16 November 2022) and
can be adapted to various models relatively easily, as in the case of the LETKF.
Simulating long-term responses of soil organic matter turnover to substrate stoichiometry by abstracting fast and small-scale microbial processes: the Soil Enzyme Steady Allocation Model (SESAM; v3.0)
Authors: Wutzler Thomas , Yu Lin , Schrumpf Marion , Zaehle Sönke
Published: November 2022

Abstract. Understanding the coupling of nitrogen (N) and carbon (C) cycles of land ecosystems requires understanding microbial element use
efficiencies of soil organic matter (SOM) decomposition. Whereas important controls of those efficiencies by microbial community adaptations have
been shown at the scale of a soil pore, a simplified representation of those controls is needed at the ecosystem scale. However, without abstracting
from the many details, models are not identifiable; i.e. they cannot be fitted without ambiguities to observations. There is a need to find, implement,
and validate abstract simplified formulations of theses processes. Therefore, we developed the Soil Enzyme Allocation Model (SEAM). The model explicitly represents community adaptation strategies of resource
allocation to extracellular enzymes and enzyme limitations on SOM decomposition. They thus provide an abstraction from several microbial functional
groups to a single holistic microbial community. Here we further simplify SEAM using a quasi-steady-state assumption for extracellular
enzyme pools to derive the Soil Enzyme Steady Allocation Model (SESAM) and test whether SESAM can provide the same decadal-term predictions as SEAM. SESAM reproduced the priming effect, the SOM banking mechanism, and the damping of fluctuations in carbon use efficiency with microbial competition
as predicted by SEAM and other more detailed models. This development is an important step towards a more parsimonious representation of soil
microbial effects in global land surface models.
An ensemble Kalman filter system with the Stony Brook Parallel Ocean Model v1.0

Published: November 2022

Abstract. This study develops an ensemble Kalman filter
(EnKF)-based regional ocean data assimilation system in which the local
ensemble transform Kalman filter (LETKF) is implemented with version 1.0 of the Stony Brook
Parallel Ocean Model (sbPOM) to assimilate satellite and in situ
observations at a daily frequency. A series of sensitivity experiments are
performed with various settings of the incremental analysis update (IAU) and
covariance inflation methods, for which the relaxation-to-prior
perturbations and spread (RTPP and RTPS, respectively) and multiplicative
inflation (MULT) are considered. We evaluate the geostrophic balance and the
analysis accuracy compared with the control experiment in which the IAU and
covariance inflation are not applied. The results show that the IAU improves
the geostrophic balance, degrades the accuracy, and reduces the ensemble
spread, and that the RTPP and RTPS have the opposite effect. The experiment
using a combination of the IAU and RTPP results in a significant improvement for both balance and analysis accuracy when the RTPP parameter is 0.8–0.9.
The combination of the IAU and RTPS improves the balance when the RTPS
parameter is ≤0.8 and increases the analysis accuracy for parameter
values between 1.0 and 1.1, but the balance and analysis accuracy are not
improved significantly at the same time. The experiments with MULT inflating the
forecast ensemble spread by 5 % do not demonstrate sufficient skill in
maintaining the balance and reproducing the surface flow field regardless of
whether the IAU is applied or not. The 11 d ensemble forecast experiments
show consistent results. Therefore, the combination of the IAU and RTPP with
a parameter value of 0.8–0.9 is found to be the best setting for the EnKF-based
ocean data assimilation system.

Abstract. Understanding the relationship between surface marine ecosystems and the export of carbon to depth by sinking organic particles is key to represent the effect of ecosystem dynamics and diversity, and their evolution under multiple stressors, on the carbon cycle and climate in models. Recent observational technologies have greatly increased the amount of data available, both for the abundance of diverse plankton groups and for the concentration and properties of particulate organic carbon in the ocean interior. Here we use synthetic model data to test the potential of using Machine Learning (ML) to reproduce concentrations of particulate organic carbon within the ocean interior based on surface ecosystem and environmental data. We test two machine learning methods that differ in their approaches to data-fitting, the Random Forest and XGBoost methods. The synthetic data is sampled from the PlankTOM12 global biogeochemical model using the time and coordinates of existing observations. We test 27 different combinations of possible drivers to reconstruct small (POCS) and large (POCL) particulate organic carbon concentrations. We show that ML can successfully be used to reproduce modelled particulate organic carbon over most of the ocean based on ecosystem and modelled environmental drivers. XGBoost showed better results compared to Random Forest thanks to its gradient boosting trees architecture. The inclusion of Plankton Functional Types (PFTs) in driver sets improved the accuracy of the model reconstruction by 58 % on average for POCS, and by 22 % for POCL. Results were less robust over the Equatorial Pacific and some parts of the high latitudes. For POCS reconstruction, the most important drivers were the depth level, temperature, microzooplankton and PO4, while for POCL it was the depth level, temperature, mixed-layer depth, microzooplankton, phaeocystis, PO4 and chlorophyll a averaged over the mixed-layer depth. These results suggest that it will be possible to identify linkages between surface environmental and ecosystem structure and particulate organic carbon distribution within the ocean interior using real observations, and to use this knowledge to improve both our understanding of ecosystem dynamics and of their functional representation within models.

Abstract. The article describes the international seismological cooperation at the beginning of the last century and how this cooperation changed due to World War I. These changes were the direct reasons leading to the foundation of the Deutsche Seismologische Gesellschaft in 1922, which changed its name to Deutsche Geophysikalische Gesellschaft two years later. The second part of the article shortly describes the further development of the relationship between German geophysicists and their international colleagues until the beginning of World War II.

The article is devoted to the unknown pages of the struggle against hunger in Northern Kazakhstan in 1921-1922 on the example of Akmola and Kostanay provinces. In the article, the author reveals the causes and consequences of the famine of 1921-1922 in Northern Kazakhstan. Here, in comparison with other affected regions, there was a big problem in the issue of food supply due to the large number of livestock deaths and several lean years. The causes of famine in Kazakhstan were the crop failure of 1921, caused by drought and locusts, lack of grain and excessive pumping of it in 1920, as well as the civil war on its territory in 1918-1920. All these reasons and the death of cattle from jute in 1920-1921 led to the utter devastation of agriculture in the republic. The famine in the Kazakh steppe was aggravated as a result of the Bolshevik government policy, when the so-called surplus agricultural products were selected and exported by food detachments, as well as due to radical changes in the economic structure and a reduction in the number of livestock among the Kazakh population. The article analyzes the demographic losses of the region, as well as studies the work of provincial commissions and public international organizations to combat hunger and its consequences.

Buddhism, the first of the world religions penetrated the western region of Central Asia. Shu-Ile region it was in late antiquity (5-6 centuries). Buddhism was widely represented until the 17-19 centuries as Lamaism of Oirat tribes. Millennium and a half, it was intermittently presented in the region. The study of the history of the spread of Buddhism in this territory dates back more than a century and a half. Some finds indicate the early (7-8 centuries) spread of Buddhism. Buddhist temple of the 13 century was explored a in Kayalyk hillfort. Throughout the 8-10 centuries Buddhism in the Shu Valley was very widespread, thanks to the support of the local community from the second center of world Buddhism -the monastic fraternities of East Turkestan. The article summarizes the latest results of the study of individual Buddhist artifacts from the Shu Valley and the Talgar settlement, the integration of data into the well-known history of Buddhism throughout the west of Central Asia is being systematized.

Annotation. Violent social experiments, violation of citizens’ rights, excesses in national politics, a refusal to take into account the peculiarities of life, customs, complex economic way of life of indigenous people, deportation to Kazakhstan of one million two hundred seven thousand representatives of various peoples and nationalities, unrest during the development of virgin lands, bureaucracy and Corruption in power structures caused various kinds of social and inter-ethnic conflicts. Careful concealment by the Soviet authorities of information about these events and a strict ban on the study of their history have led to the fact that, to date, there is no comprehensive study on this issue in historiography. The experience of identifying and preventing hotbeds of social and interethnic tension is very relevant for multinational Kazakhstan.

The article is devoted to the study of the ethnic component of the identity of the Kazakhs at the beginning of the 20th century on the basis of the works of Alikhan Bukeikhan. The article considers internal and external factors that influenced the development of the ethnic identity of the Kazakhs. Particular attention is paid to the problem of the plurality of Kazakh identities, the study of various components of identity, the mechanisms of their formation and manifestation. The authors for the first time presented a comprehensive description of the identity of the Kazakhs at the beginning of the 20th century. The theoretical and methodological basis of the study includes the ideas about the identity of B. Anderson, F. Bart, E. Hobsbaum. The main content of the study is the analysis of the scientific works of Alikhan Bukeikhan, in which the idea of the role of "Alash" in the revival of the national identity of the Kazakhs runs like a red thread. According to the authors, this issue reached its climax in December 1917 after the Second All-Kazakh Congress of the Alash Party and the decisions made at it. As a result of the study, the authors came to the conclusion that the Kazakhs of the period under review are characterized by a multiple identity, consisting of several levels. It is emphasized that the reasons for such a hierarchy in ethnic identification were the large share of the territorial component, the increased role of the religious factor and the crisis of tribal identity.
