Published: January 2023

Analysis of human emotions from multimodal data for making
critical decisions is an emerging area of research. The evolution of
deep learning algorithms has improved the potential for extracting value
from multimodal data. However, these algorithms do not often explain how
certain outputs from the data are produced.
This study focuses
on the risks of using black-box deep learning models for critical tasks,
such as emotion recognition, and describes how human understandable
interpretations of these models are extremely important. This study
utilizes one of the largest multimodal datasets available - CMU-MOSEI.
Many researchers have used the pre-extracted features provided by the
CMU Multimodal SDK with black-box deep learning models making it
difficult to interpret the contribution of individual features. This
study describes the implications of individual features from various
modalities (audio, video, text) in Context-Aware Multimodal Emotion
Recognition. It describes the process of curating reduced feature models
by using the GradientSHAP XAI method. These reduced models with highly
contributing features achieve comparable and even better results
compared to their corresponding all feature models as well as the
baseline model GraphMFN proving that carefully selecting significant
features can help improve the model robustness and performance and in
turn make it trustworthy.

In recent years, developing dopant-free carrier-selective contacts,
instead of heavily doped Si layer (either externally or internally), for
crystalline silicon (c-Si) solar cells have attracted considerable
interests with the aims to reduce parasitic light absorption and
fabrication cost. However, the stability still remains a big challenge
for dopant-free contacts, especially when thermal treatment is involved,
which limits their industrial adoption. In this study, a perovskite
material ZnTiO combining with an ultrathin
(~1 nm) SiO film and Al layer is used
as an electron-selective contact, forming an isotype heterojunction with
n-type c-Si. The perovskite/c-Si heterojunction solar cells exhibit a
performance-enhanced effect by post-metallization annealing when the
annealing temperature is 200-350 °C. Thanks to the post-annealing
treatment, an impressive efficiency of 22.0% has been demonstrated,
which is 3.5% in absolute value higher than that of the as-fabricated
solar cell. A detailed material and device characterization reveal that
post annealing leads to the diffusion of Al into ZnTiO
film, thus doping the film and reducing its work function. Besides, the
coverage of SiO is also improved. Both these two
factors contribute to the enhanced passivation effect and electron
selectivity of the ZnTiO -based contact, and hence
improve the cell performance.
Thermal and viscosity properties of inhomogeneous fluids with suspended graphene nanoparticles
Authors: Chen Junjie
Published: January 2023

The use of nanofluids in a wide variety of applications is promising,
but poor suspension stability of nanoparticles in the solution hinders
the further development of nanofluids applications. The present study
aims to provide a fundamental understanding of the thermal and viscosity
properties of inhomogeneous fluids with suspended graphene
nanoparticles. A graphite material is exfoliated to form graphene
particles, and the effect of nanoparticle volume fraction on the
material properties of inhomogeneous fluids with suspended graphene
nanoparticles is investigated at different temperatures or under
oxidation conditions. Particular emphasis is placed upon the effect of
nanoparticle volume fraction on the material properties of inhomogeneous
fluids with suspended graphene nanoparticles. The results indicate that
the bottom-up approach produces low quantities with high quality and
large flakes whereas the top-down approach yields a high concentration
of suspended flakes with a low yield of mono-layer graphene. Smaller
dispersions result in ease of addition of graphene to other desirable
emulsions to enhance the uniform coating matrix for protection
attributes graphene can provide to the coating. The pressure drop allows
the liquid precursor to flow and homogenizes the pass-through liquid of
the liquid precursor that contains thin layers of graphene. The phonon
Raman scattering changes are correlated with structural changes and
defects associated with the hydroxyl and epoxy groups in the basal plane
and a variety of alkyl and oxygen-containing functional groups
terminating the edges. Graphene-containing nanofluids provide several
advantages over the conventional fluids, including thermal
conductivities far above those of traditional solid-liquid suspensions,
a nonlinear relationship between thermal conductivity and concentration,
strongly temperature-dependent thermal conductivity, and a significant
increase in critical heat flux. Stability of the nanoparticle suspension
is especially essential for practical industrial applications.
Introduction of nanoparticles to the fluid changes density, thermal
conductivity viscosity, and specific heat. The functionalization process
decreases enhancements in thermal conductivity due to formation of
surface oxides. In development of nanofluids for heat transfer a fine
balance needs to be obtained between increases in thermal conductivity
and viscosity.

Drip irrigation soil-adapted sector design and optimal location of moisture sensors in vineyard plots: a proposed action protocol
Authors: Arnó Jaume , Uribeetxebarria Asier , Llorens Jordi , Escolà Alexandre , Rosell-Polo Joan , Gregorio Eduard , Martínez-Casasnovas José
Published: January 2023

To optimise sector design in drip irrigation systems, a protocol based
on the use of soil apparent electrical conductivity (ECa) data is
presented and applied in a commercial vineyard plot. In a first step,
before planting, ECa data up to 90 cm deep provided by the VERIS 3100
soil sensor were mapped using block ordinary kriging and then classified
(k-means algorithm) to delimit two soil classes within the plot with
different properties in terms of potential soil water content and/or
soil water regime. Contrasting the difference between soil classes
(through discriminant analysis of soil properties at different sampling
locations that covered a large part of the plot), irrigation sectors
were then designed in size and shape to match the previous soil zoning.
The second step additionally allowed the optimal location of moisture
sensors within the plot, based on a purposive soil sampling strategy,
for better soil moisture monitoring and adaptation of irrigation rates
and scheduling to soil classes.

Published: January 2023

Climate influences on below-ground plant traits seldom receive due
attention. Climate change is varying the availability of resources, soil
physical properties, rainfall events, soil mineral weathering and
leaching intensity which collectively determines soil physical and
chemical properties. Soil constraints – acidity (pH<6),
salinity(pH≤8.5), sodicity and dispersion (pH>8.5) are
major causes of wheat yield loss in arid and semi-arid cropping systems.
To cope with changing environment, plants employ adaptive strategies
such as phenotypic plasticity; a key multifaceted trait, to promote
shifts in phenotypes. Adaptive strategies are complex, determined by key
functional traits and Genotype × Environment interactions. The
understanding of molecular basis of stress tolerance is particularly
challenging for plasticity traits. Advances in sequencing and
high-throughput genomics technologies has identified functional alleles
in gene-rich regions, haplotypes, candidate genes, mechanisms and in
silico gene expression profiles at various growth developmental stages.
Our review focuses on favourable alleles for enhanced gene expression,
QTLs and epigenetic regulation of plant responses to soil constraints
including heavy metal stress and nutrient limitations. A strategy is
then described for quantitative traits in wheat by investigating
significant alleles, functional characterization of variants, followed
by gene validation using advanced genomic tools and marker development
for molecular breeding and genome editing. Also, the review highlights
the progress of gene editing in wheat, multiplex gene editing and novel
alleles for smart control of gene expression. Integration of these
genomic technologies will be effective to enhance plasticity traits and
stabilizing wheat yields on constrained soils in the face of climate
change.

Published: January 2023

Due to rapid urbanisation, urban microclimate research has become
increasingly popular in the last decade. Significant variation in
microclimate conditions can be created due to diversity in urban geometry
and it can affect outdoor thermal comfort. Biometeorological measurements
and survey were conducted in different urban settings (square, park, street)
of the city of Novi Sad during a warm autumn day in October 2019. Air
temperature, relative humidity, wind speed and globe temperature, but also
outdoor thermal comfort indices such as Mean Radiant Temperature (Tmrt) and
Physiological Equivalent Temperature (PET) were obtained for each location.
The largest differences in the biometeorological conditions are noticed
between the urban park and other urban areas. The maximum average value of
Ta was at the city square with 27.9 oC, while in the urban park and street
Ta were about 25 oC. The values of RH were the lowest at the city square.
Globe temperature (Tg) had the highest values, on average, at the city
square (about 40 oC), while the average values in the urban park and street
were about 26-28 oC. The highest average PET values are registered at the
city square (41.4 oC), followed by substantially lower average PET
registered in urban park (27.1 oC) and urban street canyon (26.2 oC). The
analysis showed that during about 70% of the time, urban dwellers experience
extreme heat stress at the city square. Contrary to that, no extreme heat
stress is noticed in urban park and street canyon.

" Globally, the use of visuo-semiotic models (VSMs) in the mathematics classroom is called for across levels and topics. Literature confirms that visual cognition/literacy in teachers is limited and that their capabilities in visual representation is low. The aim of this study was therefore to explore pre-service teachers’ (PSTs) conception of VSMs as a process in doing mathematics in the context of coordinate geometry. A survey with qualitative data was used to collect data from mathematics pre-service teachers taking the geometry module. The PSTs answered open ended questions that comprised coordinate geometry test items. Mnguni’s (2014) cognitive process of visualisation was used to analyse visualisation skills portrayed in the test. The study found that different pre-service teachers operate at different levels of visual literacy. The teacher education curriculum should therefore be systematically designed to cater for the skills lacking in the PSTs. It is also recommended that teacher training programmes sharpen their attention on bringing awareness of mathematical visual literacy among PSTs during training. "

OBJECTIVE

To explore relationships between 9-axis inertial measurement unit (IMU) output and activities of varying intensity in dogs of various sizes.

ANIMALS

20 healthy, agility course–trained dogs of various ages and sizes.

PROCEDURES

Height, weight, body condition score, age, length from IMU to the ischium, and height of IMU to the floor were recorded. Dogs performed a series of activities (rest, walk, trot, and agility course) while wearing the IMU device. IMU and video output were reviewed by independent investigators. Correlations and multiple regression models were used to explore relationships between independent variables and IMU output.

RESULTS

Calibration demonstrated excellent correlation and concordance between IMUs (intraclass correlation > 0.9) and that the IMUs reliably measured a known acceleration (gravity at rest). Resultant vector magnitude {sqrt[(x^2) + (y^2) + (z^2)]} normalized to body size was calculated from the data. IMU output clearly discriminates between activities of varying intensity in the dog.

CLINICAL RELEVANCE

The inability to accurately measure chronic pain is a barrier to the development of new, or critical evaluation of, therapeutics. Activity monitors (AM) may be the ideal diagnostic target since they are small and provide objective data that can be collected while the pet remains in its natural environment. These results demonstrate the concurrent and predictive validity of the IMU tested. Our long-range goal is to validate an open-source algorithm for the IMU so activity in a pet’s natural environment can be used as an outcome measure in future studies.

De Bruijn sequence is an important kind of nonlinear shift register sequence, which has a very wide range of applications in the fields of communication and cryptography. From the perspective of the relationship between linear terms, quadratic terms and cubic terms in the feedback functions of de Bruijn sequences, some new necessary conditions for feedback functions of de Bruijn sequences are obtained. Some examples show that the known necessary conditions cannot deduce the proposed necessary conditions.

Los otros trabajos de AEVAL: análisis y desarrollos metodológicos
Authors: Ruiz Martínez Ana
Published: January 2023

El artículo describe un conjunto de trabajos desarrollados por AEVAL a lo largo de sus años de existencia, que van más allá de sus dos funciones principales: la evaluación de las políticas y los programas públicos y la promoción de la gestión de calidad en las administraciones públicas. El desarrollo de estos trabajos posibilitó el mantenimiento de la actividad de AEVAL durante los años en que no se aprobaban planes de trabajo de evaluación. Pero por otra parte, muchos de estos trabajos aportaron soluciones innovadoras a viejos problemas de gestión y tuvieron una acogida muy favorable tanto por parte de las organizaciones que los habían encargado como por parte de otros actores interesados. Sin embargo, la resistencia al cambio y el refuerzo tras la crisis de 2008 de los aspectos más conservadores de la cultura administrativa y política hizo que algunos de estos trabajos nunca se llevaran a la práctica.

Origins of a Granted Word to the Peoples of Siberia
Authors: Belyakov A. V.
Published: January 2023

The article studies the practice of announcing the Granted Word on behalf of the Moscow sovereign to the peoples of Siberia, implemented in the late 16th – early 17th century. It concludes that in fact such practice arose twice – in 1599 and 1623. For the first time muscovites used the Granted Word as an element of policy intended to strengthen the position of the new ruling dynasty. The reasons behind its revival after the period of oblivion are not clear. An opinion is expressed that the roots of this phenomenon went back to the so-called charter with a golden seal and charters of settlement, which in their turn went back to the granted letters of the period of the Mongolian vassalage. Such documents were well known in the area that once was part of the Golden Horde and used there as consolidating tool of the vassal oath of the nobility originated in Moscow. Thus, the practice of announcing of the Granted Word combined confirmation of the rights to land on behalf of the monarch, known since the Horde times, and conclusion of a kind of collective agreement with the Russian tsar (included the obligation to protect the sovereign from any crimes against him). This example shows that in the late 16th – early 17th century Russian administration system developed a power distribution mechanism intended to delegate tsar’s power to the people of Siberia, which had recently become part of the Russian state. This was especially crucial due to the fact that this territory was located significantly far from the capital. To maintain state unity, it was necessary to create the illusion of the direct involvement of the Moscow sovereign in the administration process of the lands beyond the Urals.
Saint Isaac’s Cathedral as a Political Space: Transformation of the Image and the Search for Interpretations before and after the Russian Revolution of 1917
Authors: Lyubeznikov O. A.
Published: January 2023

The article analyzes the problem of transformation of imperial political spaces in the historical context of the 19th – 20th centuries. The main attention in the article is focuses on the dominant of the architectural landscape of St. Petersburg – St. Isaac’s Cathedral. The struggle for its symbolic appropriation reflected the peripeteias of the socio-political development of tsarist, revolutionary and Soviet Russia. The article aims to study the process of transformation of symbolic meaning of St Isaac’s Cathedral and to analyze all comprehension models of that monument. The initial purpose of its construction was to honor the Russian monarchy, but after the Russian Revolution it required a new interpretation that would fit new realities. Based on numerous unpublished documents from the seven archives of St. Petersburg, the author concludes that before the Revolution St. Isaac’s Cathedral was marked on the symbolic map of Petrograd not only as a church but as a right-wing conservative political space, a visible monument glorifying the House of Romanov. The anti-monarchist revolution changed the fate of the building and its image forever. In the 1920s the perception of the cathedral caused a furious fight in society. It was a period of intense rivalry between three symbolic programs – exclusively church’s interpretation, interpretation of the cathedral as a monument of art, and antireligious model of the “anti-temple” – “the former St. Isaac’s Cathedral”.

Objectives:

Primary objective – Phase I: The primary objective of this study was as follows: (1) To identify common protective resilient factors that enabled the adult female cancer survivors to cope with the cancer experience. (2) To identify potential barriers to the resilience of adult female cancer survivors. Secondary objective – Phase II: The secondary objective of this study was to develop and validate a resilience tool for cancer survivorship.

Material and Methods:

A mixed approach using sequential exploratory design was used in the study. A qualitative approach using phenomenology design was used in the first phase followed by a quantitative approach in the second phase. In the first phase, in-depth interviews were conducted until data saturation with 14 female breast cancer survivors chosen by purposive and maximum variation sampling methods based on inclusion criteria. The researcher used Colaizzi’s data analysis framework to analyse the transcripts. Findings were configured as protective resilience factors and barriers to resilience. Based on the analysis of the qualitative phase, the researcher developed a 35-item resilience tool for cancer survivorship. Content validity, criterion validity and reliability of the newly developed instrument were assessed.

Results:

In the qualitative phase, the mean age of the participants was 57.07 years and the mean age at diagnosis was 55.5 years. The majority 11 (78.57%) of them were homemakers. All 14 (100%) of them had undergone surgery. The majority 11 (78.57%) of them had all three modes of therapy, that is, surgery, chemotherapy and radiation therapy. The categories of themes identified are presented under two main headings, that is, protective resilience factors and barriers to resilience. The theme categories identified under protective resilience factors were personal, social, spiritual, physical, economic and psychological factors. The barriers to resilience identified were lack of awareness, medical/biological barriers, social, financial and psychological barriers. The developed resilience tool had a content validity index of 0.98, a criterion validity of 0.67, internal consistency of 0.88 and stability of 0.99 at a 95% confidence interval. Principle component analysis (PCA) was used to validate the domains. PCA of protective resilience factors (Q1–Q23) and barriers to resilience (Q24–Q35) had Eigenvalues of 7.65 and 4.49, respectively. The resilience tool for cancer survivorship was found to have good construct validity.

Conclusion:

The present study has identified the protective resilience factors and barriers to resilience among adult female cancer survivors. The developed resilience tool for cancer survivorship was found to have good validity and reliability. It will be useful for nurses and all other healthcare professionals to assess the resilience needs of cancer survivors and to provide need-based quality cancer care

The increasing number of earthquakes is one of the critical reasons for shifting Chennai from zone II (least active) to zone III (moderately active) by the Bureau of Indian Standards. The soil column's natural frequency and time period are the key parameters for seismic design and construction. Furthermore, compared to shear wave velocity, the fundamental period is a key parameter for site amplification in the recent trend because it accounts for both stiffness and depth of soil sediments. In order to determine the fundamental frequency and typical site period, an equivalent linear 1-D ground response analysis was performed in the Chennai region using ProSHAKE 2.0 software. A contour map was created using ArcGISPro software for the study area's fundamental and characteristic site periods. The longer the soil column's site period, the greater the amplification and the greater the seismic threat. Finally, buildings with a natural period of 0.6 - 1 s should be avoided in the southeastern region of the study area because of the resonance.

In this study, the synthesis and physico-chemical properties of sustainable poly(butylene succinate-dilinoleic succinate) (PBS-DLS) copolymers modified with hydrophilic poly(ethylene glycol)(PEG) are discussed in context of structure-properties relationship of polymeric materials and their processibility. The copolymers of variable segmental composition and containing green monomers such as succinic acid and dilinoleic diol, were successfully synthesized by non-solvent two-step transesterification and polycondensation reaction. Synthesized polymers were collected as crystallized filaments directly from the reactor. These filaments were used without any postprocessing for 3D printing. Characterization of chemical structure confirmed the presence of functional ester and ether groups. Crystallized copolymers revealed spherulitic morphology and phase transitions which were dependent from the segmental composition. Interestingly, incorporation of 5 wt% PEG into copolymers containing higher hard segments content (70 wt%) disturbed the banded spherulitic morphology of copolymers, contributed to the increase of elasticity up to 830%, and reduced the water contact angle in comparison to copolymers containing 60 wt% of PBS hard segments. The mechanical properties and printability of the copolymers depended also on their segmental composition, where higher hard segment content (70 wt%) facilitated better printability compared to polymers containing 60 wt% of PBS hard segments. Additionally, we demonstrate that new copolymers were suitable for electrospinning yielding nanofibers of average fiber diameters between 400 and 600 nm. The obtained results showed excellent processability, rubber-like elasticity and improved hydrophilicity of new polymers thus indicating that segmental composition can be important design parameter in preparation of new green copolymers for advanced processing by 3D printing and electrospinning.

The first total synthesis of (+)-tanzawaic acid B, a natural polyketide bearing a pentadienoic ester and octalin moiety, has been accomplished. The synthetic improvement from previous synthetic conditions facilitated our gram-scale synthesis of the chiral octalin that possesses seven stereogenic centers and that is the core skeleton of almost all of the tanzawaic acid family.

Ethanol dehydrogenation to acetaldehyde with mesoporous Cu-SiO2 catalysts prepared by aerosol-assisted sol-gel

Copper based catalysts are central for carrying dehydrogenation reactions. However, these materials are prone to deactivation by sintering and coke deposition. Irreversible sintering occurring during reaction (under the effect of temperature) is known to decrease both activity and selectivity, where the unwanted dehydration activity of the support might also play an important role. From this perspective, the quite unreactive silica supports may be attractive. However, using classical catalyst preparation methods (e.g. impregnation), it is a challenge to obtain a stable and homogeneous dispersion of Cu over SiO2 owing to the weak support-active phase interactions. Taking a sidestep, aerosol-assisted sol-gel is a promising alternative for the facile preparation of mesostructured metallosilicates with high metal dispersion. Here we report, for the first time, Cu-SiO2 made by the aerosol-assisted sol-gel method and exploited in the ethanol non-oxidative dehydrogenation to acetaldehyde. These catalysts are compared with a series of catalysts made by impregnation to investigate, through a thorough characterization survey, the effect of the synthesis procedure as well as the effect of Cu loading. We show that aerosol-made catalysts do not suffer heavy sintering, reach high ethanol conversions with acetaldehyde selectivity above 75%, and only slowly deactivate upon time due to a (reversible) coking phenomenon.

Published: January 2023

CHARMM is rich in methodology and functionality as one of the first programs addressing problems of molecular dynamics and modeling of biological macromolecules and their partners, e.g., small molecule binding ligands. When combined with the highly developed CHARMM parameters for proteins, nucleic acids, small molecules, lipids, sugars, and other biologically relevant building blocks, and the versatile CHARMM scripting language, CHARMM has been a trendsetting platform for modeling studies of biological macromolecules. To further enhance the utility of accessing and using CHARMM functionality in increasingly complex workflows associated with modeling biological systems, we introduce pyCHARMM, Python bindings, functions, and modules to complement and extend the extensive set of modeling tools and methods already available in CHARMM. These include access to CHARMM function-generated variables associated with the system (psf), coordinates, velocities and forces, atom selection variables and force field related parameters. The ability to augment CHARMM forces and energies with energy terms or methods derived from machine learning or other sources, written in Python, CUDA or OpenCL and expressed as Python callable routines is introduced together with analogous functions callable during dynamics calculations. Integration of Python-based graphical engines for visualization of simulation models and results are also accessible. Loosely coupled parallelism is available for workflows such as free energy calculations, using MBAR/TI approaches or high-throughput multisite 𝜆-dynamics (MSλD) free energy methods, string path optimization calculations, replica exchange and molecular docking with a new Python-based CDOCKER module. CHARMM accelerated platform kernels through the CHARMM/OpenMM API, CHARMM/DOMDEC and CHARMM/BLaDE API are also readily integrated into this Python framework. We anticipate that pyCHARMM will be a robust platform for the development of comprehensive and complex workflows utilizing Python and its extensive functionality as well as an optimal platform for users to learn molecular modeling methods and practices within a Python-friendly environment such as Jupyter Notebooks.

Published: January 2023

Oligosilanes are important compounds in industrial and synthetic chemistry. Here, we develop a general approach for the synthesis of linear and cyclic oligosilanes via the reductive activation of readily available chlorosilanes. The efficient and selective generation of silyl anion intermediates, which are arduous to achieve by other means, allows for the synthesis of various novel oligosilanes. In particular, this work presents a modular synthesis for a variety of functionalized cyclosilanes, which may give rise to materials with distinct properties from linear silanes but remain challenging synthetic targets. In comparison to the traditional Wurtz coupling, our method features milder conditions and improved chemoselectivity, broadening the functional groups that are compatible in oligosilane preparation. Computational studies support a mechanism whereby differential activation of two sterically and electronically distinct chlorosilanes are achieved in an electrochemically driven radical-polar crossover mechanism.
