Ultrafast Nano-Silver Modified Fluorinated Carbon Nanotubes Cathode Enables Advanced Lithium/Sodium/Potassium Primary Batteries
Authors: Luo Zhenya , Chen Duanwei , Chang Qihong , Wu Dazhuan , Xie Shuhong , Pan Yong , Pan Junan , Ouyang Xiaoping
Published: July 2023

The application of fluorinated carbon (CFx)-based
lithium/sodium/potassium primary batteries (LPBs/SPBs/PPBs) with
superior theoretical energy density in high-power devices remains
limited due to the poor rate performance resulting from the low
intrinsic conductivity of highly fluorinated CFx materials. Herein,
novel nano-silver modified fluorinated carbon nanotubes (FCNTs@Ag-x)
composites with high electrical conductivity were prepared without
sacrificing the high fluorine content. The dual excellent performance
achieved by the FCNTs@Ag-200 cathode is attributed to the
three-dimensional conductive network synergistically constructed by the
interlaced FCNTs and coated nano-Ag, together with electrochemically
active C-F bonds co-regulated by Ag atoms and curvature, as well as
abundant conductive semi-ionic C-F bonds and graphite-like sp2 C=C
bonds, and few inactive C-F2 bonds. The FCNTs@Ag-200 cathode delivers
very high energy densities of 2167, 1930, and 2150 Wh kg-1 for LPBs,
SPBs, and PPBs, respectively, close to the theoretical energy density.
The Li/FCNTs@Ag-200 battery exhibits an ultimate power density of up to
80501 W kg-1 at an ultrafast rate of 50 C and can withstand a pulse
discharge of 150 C (~129.75 A g-1). Remarkably,
unprecedented power densities of 36650 and 40672 W kg-1 are achieved at
a record rate of 25 C using FCNTs@Ag-200 as the cathode for Na/CFx and
K/CFx batteries, respectively, which is a significant improvement over
the state-of-the-art. Therefore, the advanced CFx-based primary
batteries developed here are promising in applications that
simultaneously require fast discharge, high energy density, high power
density, and long-term storage.
Indiscriminate aggression and threat-level insensitive egg rejection maintain host susceptibility towards sexually dimorphic diederik cuckoos
Authors: York Jennifer
Published: July 2023

The existence of adult sexual dimorphism is typically explained as a
consequence of sexual selection, yet coevolutionary drivers of sexual
dimorphism frequently remain untested. Here, I investigate the role of
sexual dimorphism in host-parasite interactions of the brood parasitic
diederik cuckoo, Chrysococcyx caprius. Female diederik cuckoos are more
cryptic in appearance and pose a threat to the clutch, while male
diederik cuckoos are conspicuous and not a direct threat. Specifically,
I examine whether sexual dimorphism in diederik cuckoos provokes
threat-level sensitive responses in Southern red bishop, Euplectes orix,
hosts. I use experimentally simulated nest intrusions to test whether
hosts have the capacity to differentially (i) detect, and/or (ii)
discriminate between, male and female diederik cuckoos, relative to
controls. Overall, I found no evidence that diederik cuckoos differ in
detectability, since both sexes are comparable to controls in the
probability and speed of host detection. Furthermore, neither male nor
female hosts discriminate between sexually dimorphic diederik cuckoos
when engaging in frontline nest defences. However, hosts that witnessed
a male diederik cuckoo during the trial were more than twice as likely
to reject odd eggs compared to those that saw a control. Moreover, hosts
were more likely to reject experimental eggs when exposed to a male
compared to a female diederik cuckoo: the reverse of a beneficial
threat-level sensitive response. While the cryptic appearance of female
diederik cuckoos does not differentially avoid detection by hosts, it
does appear to provide the benefit of anonymity given the egg rejection
costs of male-like appearance in the nest vicinity. These findings have
implications for the evolution and maintenance of sexual dimorphism
across the Cuculidae, and highlight the value of testing assumptions
about the ecological drivers of sexual dimorphism.
Shingle Cell IV Characterization Based on Spatially Resolved Host Cell Measurements
Authors: Kunze Philipp , Demant Matthias , Krieg Alexander , Tummalieh Ammar , Wöhrle Nico , Rein Stefan
Published: July 2023

Each solar cell is characterized at the end-of-line using
current-voltage ( IV) measurements, except shingle cells, due to
multiplied measurement efforts. Therefore, the respective host cell
quality is adopted for all resulting shingles, which is sufficient for
samples with laterally homogeneous quality. Yet, for heterogeneous
defect distributions, this procedure leads to (i) loss of high quality
shingles due to defects on neighboring host cell parts, (ii) increased
mismatch losses due to inaccurate binning and (iii) lack of
shingle-precise characterization. In spatially resolved host
measurements, such as electroluminescence images, all shingles are
visible along with their properties. Within a comprehensive experiment
840 hosts and their resulting shingles are measured. Thereafter, a deep
learning model has been designed and optimized which processes
host-images and determines IV parameters like efficiency or fill
factor, IV curves and binning classes for each shingle cell. The
efficiency can be determined with an error of 0 .06 % abs
enabling a 13 % abs improvement in correct assignment of shingles to
bin classes compared to industry standard. This results in lower
mismatch losses and higher output power on module level as demonstrated
within simulations. Also IV curves of defective and defect-free
shingle cells can be derived with good agreement to actual shingle
measurements.
Vagino-laparoscopic conservative strategy of hysterectomy in indicated cases of severe pelvic endometriosis followed by 24 months of depot-medroxyprogesterone acetate therapy—a long-term symptom-solving treatment model: an observational study
Authors: Purohit Ram , Sharma Jaygopal , Meher Devajani , Samy Mohammed
Published: July 2023

Objective: To demonstrate the long-term outcome of a symptom-solving
treatment model (SSTM). Design: Observational study between June 2016
and December 2022. Setting: Purohit General Hospital Population: 68
consecutive candidates of hysterectomy for severe pelvic endometriosis.
Methods: Candidates were treated by the SSTM, which constitutes a
systematic vagino-laparoscopic conservative strategy of hysterectomy
with preservation of the ovary or ovaries followed by 24 months of
postoperative depot-medroxyprogesterone acetate (DMPA) therapy. Cases
were followed up to December 2022, 2.5 years beyond the last
hysterectomy in May 2020. Main outcome measures: Relief of
endometriosis-associated symptoms and prevention of recurrence in the
long term. Results: Symptomatic relief of endometriosis-related pain,
such as cyclical dysmenorrhoea, pelvic pain, dyschezia, and vaginal
pain, occurred in all 68 (100%) cases from the next expected date of
menstruation. None of the cases showed a recurrence of
endometriosis-related pelvic pain; overall, 37 (54.41%) cases crossed
4–6 years, and 31 (45.58%) cases crossed 2.5–4.0 years following the
hysterectomy operation. Four (5.88%) cases had non-endometriotic pelvic
pain. None of the cases required repeat surgery or had any major side
effects or complications due to DMPA. No major perioperative
complications were observed. The results were achieved without the
requirement of challenging extensive retroperitoneal laparoscopic
dissection, ureterolysis, and rectum surgeries. Conclusions: This SSTM
can be an option in indicated cases of severe pelvic endometriosis to
provide symptom relief and prevent the recurrence of
endometriosis-associated pelvic pain in the long term.
Community richness is the main factor determining the structure of ant-plant mutualistic networks along environmental water gradients
Authors: Melati Bruno , Jr. Paulo Guimarães , Leal Laura Carolina
Published: July 2023

Many plant species rely upon ants to protect against herbivores. In arid
environments, these plants often form stronger bonds with dominant ant
species that, in turn, provide a better anti-herbivory defense than low
aggressive subordinate ants. Dominant ants typically claim the plants
producing more nutritious nectar, commonly leaving less valuable plants
to be guarded by lower-quality bodyguards. As water scarcity increases,
the value of the extrafloral nectar also increases, which can increase
the control of the most valuable plants by dominant ants and of the
displacement of outcompeted ants to less valuable plants, reducing niche
overlap among ant species and, consequently, the generalization of
ant-plant interactions at the community level. To evaluate this
hypothesis, we crossed data from 63 empirical ant-plant networks with
the mean precipitation rate of the sites and period in which the
interactions were sampled. As the environment dries, ant-plant networks
decreased in species richness but maintained other network properties.
Surprisingly, the decline in the number of ant and plant species engaged
in the mutualism along the precipitation gradient increased the
interaction generalization in drier habitats. But this increased
generalization is possible due to the increase in probability of
interaction between all plant and ant species due to the lower richness.
Hence, water availability primarily influences ant-plant interactions
through its impact on ant and plant communities. This has significant
eco-evolutionary consequences, as possibly increasing the persistence of
this networks in drier environments, demonstrating a new pathway through
which environmental factors can impact ecological interactions.
Sinonasal Inverted Papilloma and predictors of Health-Related Quality of Life after Endonasal Endoscopic Surgery: a prospective cohort study
Authors: Heijer Marc den , Joustra Gonneke , Vermeulen Karin , Korsten-Meijer Astrid , Feijen Robert
Published: July 2023

Objectives: Existing knowledge on Health Related Quality of
Life (HRQoL) after surgical removal of sinonasal inverted papilloma (IP)
is limited. Moreover, predictors for a better or worse postoperative
HRQoL outcome are not known. Our aim was to assess HRQoL in all three
health domains (physical, psychological and social), track its
postoperative trajectory, investigate if preoperative observations could
predict distinct postoperative HRQoL outcomes, and evaluate whether
physicians’ interventions could contribute to improved postoperative
HRQoL. Design: Prospective cohort study. Setting:
Tertiary referral hospital. Participants: Seventy-four patients
who underwent surgery for an IP were included. They were asked to fill
in the Endonasal Endoscopic Sinus and Skull Base Surgery Questionnaire
(EES-Q) preoperatively, and then two weeks, three months, and one year
postoperatively. Main outcome measures: Linear mixed models
(LMM) analyses were performed to evaluate the overall postoperative
HRQoL and the separate health domains, as well as the impact of specific
variables (sex, age, ASA classification, smoker, Krouse staging,
preoperative EES-Q score, type of surgery and postoperative antibiotics)
on HRQoL improvement. Results: The total EES-Q score
(P<.001) as well as the physical (P<.001),
psychological (P=.049), and the social (P=.002) domains significantly
improved postoperatively. ASA classification (P=.049), preoperative
EES-Q score (P<.001) and postoperative antibiotics (P=.036)
were significant variables. Conclusions: Overall HRQoL, as well
as each of the three health domains, improved significantly. A higher
ASA score, a higher preoperative EES-Q score, and the administration of
postoperative antibiotics were significant predictors for better HRQoL
recovery postoperatively. Further research is necessary to confirm these
results.
Strengthening effect of cyclic load on siltstone and its macro--micro fracture mechanism
Authors: Yang Pengjin , Miao Shengjun , Wang Hui , Peng Li , Mingchun Liang
Published: July 2023

Cyclic loading affects the mechanic characteristics and long-term
stability of geotechnical engineering. Although the fatigue failure and
weakening effect of cyclic load have been extensively studied, the
strengthening effect and its failure mechanism are somewhat unclear. In
this study, a series of cyclic-to-monotonic loading tests with the upper
limit in elastic deformation stages was conducted on siltstone. Results
show that the siltstone in the test is a typical porous weakly cemented
rock, and its characteristic stress can be determined by volume strain
curve, AE counts and ultrasonic velocity. The strengthening and
weakening effects of siltstone under cyclic loading depend on the upper
limit of cyclic load. When the upper limit of cyclic load is in the
elastic deformation stage, the strength, elastic modulus, and
characteristic stress of siltstone were improved significantly. The
microscopic mechanism of strengthening effect was analysed through AE
b-value, sources, and electron microscopy scanning. Under the
uniaxial compression, the evolution law of AE sources shows a
specifically spatio-temporal zonal disintegration phenomenon. The
essential reasons for the strengthening effect are mainly reflected that
the micro fracture mode was changed. Under the cyclic load test, the
spatial distribution of AE sources of siltstone is more uniform, which
indicates the skeleton area of the specimen which can bear the axial
load increased. However, the burst of AE signals is delayed, and the
crack scale is small due to the strengthening effect. The difficulty of
geotechnical engineering disaster prediction and prevention was greatly
increase, and the attention should be paid to similar geotechnical
engineering.
How to perform modeling with independent and preferential data jointly?
Authors: Pereira Mario Figueira , Conesa David , López-Quílez Antonio , Paradinas Iosu
Published: July 2023

Continuous space species distribution models (SDMs) have a long-standing
history as a valuable tool in ecological statistical analysis.
Geostatistical and preferential models are both common models in
ecology. Geostatistical models are employed when the process under study
is independent of the sampling locations, while preferential models are
employed when sampling locations are dependent on the process under
study. But, what if we have both types of data collectd over the same
process? Can we combine them? If so, how should we combine them? This
study investigated the suitability of both geostatistical and
preferential models, as well as a mixture model that accounts for the
different sampling schemes. Results suggest that in general the
preferential and mixture models have satisfactory and close results in
most cases, while the geostatistical models presents systematically
worse estimates at higher spatial complexity, smaller number of samples
and lower proportion of completely random samples.

Published: July 2023

In this study, the effect of different weld projections on the mechanical properties of stud welds was analyzed using the Taguchi experiment planning method, using a projection welding machine with a capacity of 100 kVA with MFDC transformer. The samples were subjected to the tensile rupture force test with a destructive test device. The aim of this study was to ensure product safety by capturing the spot-welding quality, which is determined by the specifications of the automotive main industry, using a bolt with a lower weight. In this study, 1.5 mm WSS-M1A365-A11 uncoated steel sheet and 8.8 quality M6x1.00x25 triple projection uncoated welding bolts and 8.8 quality M6x1.00x18.5 ring shaped weld bolts were used as stud welding bolts. Different welding times, different welding currents and different welding clamping forces were used on the WSS-M1A365-A11 steel sheet samples in the stud welding operation with bolts. Taguchi analysis showed that ring shaped stud weld bolts required welding parameters of 32 ms welding time, 27 kA welding current and 500 daN welding force, while triple projection stud welding was found to perform the best optimum weld with 23 ms welding time, 18 kA welding current and 350 daN force.

Published: July 2023

The purpose of this study is to investigate in what ways kindergarten teachers explain their understanding and practices of education for sustainable development. The study uses the term “green sustainability” to refer to the concept of caring for nature, the environment, and the earth’s climate in ways which meet basic human needs and preserve them for future generations. The data are generated from six focus groups conducted in 2020. The sample is comprised of 23 kindergarten teachers representing six kindergartens. Analyses of the data material revealed the following theme-based categories: 1) digital, multimodal resources, 2) experiences in nature, 3) from farm to fork, 4) sorting garbage and food waste, and 5) avoiding waste. The findings indicate that existing practices are largely in accordance with longstanding traditions within the kindergartens. The study also indicates that there is a need for critical and reflective practices to meet the needs of children in developing a nascent understanding of sustainable development. Currently, 21st century skills that can be applied to sustainability challenges include critically evaluating different pieces of information, connecting knowledge, collaborating creatively, and communicating across disciplines.
La producción del espacio y las relaciones de poder en la Sala de Emergencias
Authors: Molina Ramón Jose Arturo
Published: July 2023

El presente trabajo realiza una breve revisión de los principales planteamientos teóricos y metodológicos de lo que se conoce como el giro espacial y geográfico en las Ciencias Sociales, los elementos desarrollados fueron utilizados para elaborar una estrategia analítica, que permitió aproximarse a un fenómeno empírico de naturaleza geográfica o espacial. En ese sentido, en el trabajo analiza la Sala de Emergencias de un hospital público, para describir la producción del espacio desde la perspectiva de un médico de posgrado. De esa forma, se aborda con mayor profundidad el análisis espacial y geográfico de Tim Cresswell (2013) Urabayen y Casero (2018) y Foucault (1979; 1999). Asimismo, el trabajo pone en práctica una metodología transdiciplinaria, que combina el análisis socioespacial (Tirado, 2009), la multimetodología autobiográfica (Guitart, 2012), los métodos visuales y narrativos (Mannay, 2017) con la cartografía corporal (Colectivo de Geografía Crítica del Ecuador, s.f). La propuesta metodológica además involucra la aplicación de programas informáticos para el análisis del espacio como DepthMapX, para realizar sintaxis espacial y Gephy para el análisis de redes. Se identificó que existe una composición arquitectónica panóptica y jerarquizada del espacio, así como de una relación asimétrica de la distribución del espacio en la Sala de Emergencias. Todo esto permite la presencia de un orden jerárquico y de segmentos segregados o exclusivos. Asimismo, se evidenció como la composición arquitectónica y el ordenamiento en el medio hospitalario genera efectos sobre los cuerpos de los médicos de posgrado, particularmente una creciente desmoralización, desgaste profesional y estados de depresión.

Visual Coherence for Augmented Reality
Authors: Gorbunov A. L.
Published: July 2023

Introduction. The 2020s were marked by the emergence of a new generation of computer simulators using augmented reality. One of the promising advantages of augmented reality technology is the ability to safely simulate hazardous situations real-world. A prerequisite for realizing this advantage is to provide the visual coherence of augmented reality scenes: virtual objects must be indistinguishable from real ones. All IT leaders consider augmented reality as a next “big wave”; thus, the visual coherence is becoming a key issue for IT in general. However, it is in aerospace applications that the visual coherence has already acquired practical significance. An example is Boeing's development of an augmented reality flight simulator, which began in 2022. Visual coherence is a complex problem, one of the aspects of which is to provide the correct overall coloration of virtual objects in an augmented reality scene. The objective of the research was to develop a new method of such tinting.

Materials and Methods. The developed method (called spectral transplantation) uses two-dimensional spectral image transformations.

Results. A spectral transplantation technology is proposed that provides direct transfer of color, brightness, and contrast characteristics from the real background to virtual objects. An algorithm for automatic selection of the optimal type of spectral transformation has been developed.

Discussion and Conclusion. Being a fully automatic process without recording lighting conditions, spectral transplantation solves a number of complex problems of visual coherence. Spectral transplantation can be a valuable addition to other methods of providing visual coherence.
Placement of Multiple Virtual Objects in Physical Space in Augmented Reality Applications
Authors: Alpatova M. V. , Rudyak Yu. V.
Published: July 2023

Introduction. The challenges of placing virtual objects in a real-world environment limit the potential of augmented reality (AR) technology. This situation identifies a gap in scientific knowledge that requires additional research. Therefore, the main task of this study was to develop a method for optimal placement of virtual objects, in which the objective function of comfort was minimized. This approach is aimed at improving AR systems and developing the corresponding theory.

Materials and Methods. The conducted research was based on the analysis of the placement of virtual objects in AR/VR applications with particular emphasis on optimization. The concept of comfort of placement was proposed, taking into account the size of the object and the distance to the boundaries of free space in X, Y, Z coordinates.

Results. As part of the study, formulas were obtained for the optimal placement of objects with an arbitrary comfort function. The basic criterion was to minimize the difference between comfort levels from different sides of the object. It was found that a successful placement of objects required taking into account their size and comfort zones, as well as solving a system of n linear equations.

Discussion and Conclusion. The results obtained make an important contribution to the study of the problem of placing virtual objects in AR/VR/MR. They open up new opportunities for improving user interaction and conducting further research in the field of spatial computing. Possible directions for further development are dynamic adjustments and integration of the results into various XR scenarios.

Abstract. Mining activities can cause environmental pollution, as happened in the villages of Wadas and Kendeng, Central Java. The aim of this research is to classify the level of environmental pollution in Central Java based on a number of parameters, namely, the number of villages affected by water pollution, air pollution and soil pollution. The clustering method in this study uses the K-Means algorithm. The best cluster is 0.51 with 2 clusters. Based on the level of environmental pollution, the findings reveal that Central Java is divided into two city/district clusters: cluster 1 (with a low pollution level) with 14 members, and cluster 2 (with a low pollution level) with 24 members.
