Authors: Werheni Ammeri Rim , Hassen Wafa , Mehri Ines , Khelifi Nesrine , Hassen Abdennaceur
Published: November 2022

Bioaugmentation by Pseudomonas strains is widely used for the removal of pollutants in wastewater. In this study, we aimed to determine the removal of pentachlorophenol (PCP, 800 mg·L–1) in secondary wastewater by the bioaugmentation process. We determined the effects of using three surfactants, namely sodium dodecyl sulfate (SDS), cetyl-tri-methyl-ammonium bromide (CTAB), and Tween 80 for PCP removal. We determined the effect of the role of PCP surfactant for the biofilm and auxin production of the selected bacterial strain of P. fluorescens GU059580. High-performance liquid chromatography and spectroscopic analysis were used to determine PCP removal and bacterial growth, respectively. Biofilm production was determined using 96-well polystyrene plates, and auxin production was determined using spectrophotometric measurement at 535 nm. The results showed the removal of PCP from wastewater by P. fluorescens GU059580 is about 90.12%. The PCP removal from wastewater showed an improvement of about 96.5% after the addition of Tween 80, whereas significant biofilm formation was found in the mineral liquid medium supplemented with PCP and Tween 80, with a value of 3.78. The highest concentration of auxin was found in the presence of PCP without surfactants, showing a value of 1.7 mg·L–1. To conclude, P. fluorescens GU059580 can be used in bioreactors or some specific wastewater treatment processes for bioremediation.

Authors: Fresán Ujué , Bernard Paquito , Fabregues Sergi , Boronat Anna , Araújo-Soares Vera , König Laura M , Chevance Guillaume
Published: November 2022

Background

Changing current dietary patterns into sustainable healthy diets (ie, healthy diets with low environmental impact and socioeconomic fairness) is urgent. So far, few eating behavior change interventions have addressed all the dimensions of sustainable healthy diets at once and used cutting-edge methods from the field of digital health behavior change.

Objective

The primary objectives of this pilot study were to assess the feasibility and effectiveness of an individual behavior change intervention toward the adoption of a more environmentally sustainable healthy diet as a whole and changes in specific relevant food groups, food waste, and obtaining food from fair sources. The secondary objectives included the identification of mechanisms of action that potentially mediate the effect of the intervention on behaviors, identification of potential spillover effects and covariations among different food outcomes, and identification of the role of socioeconomic status in behavior changes.

Methods

We will run a series of ABA n-of-1 trials over a year, with the first A phase corresponding to a 2-week baseline evaluation, the B phase to a 22-week intervention, and the second A phase to a 24-week postintervention follow-up. We plan to enroll 21 participants from low, middle, and high socioeconomic statuses, with 7 from each socioeconomic group. The intervention will involve sending text messages and providing brief individualized web-based feedback sessions based on regular app-based assessments of eating behavior. The text messages will contain brief educational messages on human health and the environmental and socioeconomic effects of dietary choices; motivational messages to encourage the adoption of sustainable healthy diets by participants, providing tips to achieve their own behavioral goals; or links to recipes. Both quantitative and qualitative data will be collected. Quantitative data (eg, on eating behaviors and motivation) will be collected through self-reported questionnaires on several weekly bursts spread through the study. Qualitative data will be collected through 3 individual semistructured interviews before the intervention period, at the end of the intervention period, and at the end of the study. Analyses will be performed at both the individual and group levels depending on the outcome and objective.

Results

The first participants were recruited in October 2022. The final results are expected by October 2023.

Conclusions

The results of this pilot study will be useful for designing future larger interventions on individual behavior change for sustainable healthy diets.

Authors: Borghouts Judith , Eikey Elizabeth V , De Leon Cinthia , Schueller Stephen M , Schneider Margaret , Stadnick Nicole A , Zheng Kai , Wilson Lorraine , Caro Damaris , Mukamel Dana B , Sorkin Dara H
Published: November 2022

Background

Digital mental health interventions have the potential to increase mental health support among isolated older adults. However, the older adult population can experience several barriers to accessing and using digital health resources and may need extra support to experience its benefits.

Objective

This paper aimed to understand what older adults experience as an important aspect of support during engagement in a digital mental health program. The program entailed 3 months of staff support to participate in digital literacy training and engage with the digital mental health platform myStrength, which offers support for a range of mental health challenges, including depression and anxiety.

Methods

A total of 30 older adults participated in surveys and interviews to assess their experience of participating in a digital mental health program provided by county mental health services. As part of the program, participants attended 4 classes of digital literacy training, had access to the digital mental health platform myStrength for 2 months with staff support (and 10 months after the program without support), and received support from program staff during the entire 3-month program. Survey data were analyzed using descriptive statistics, and interview data were analyzed using thematic analysis.

Results

A thematic analysis of the interview data revealed that participants valued ongoing support in 3 main areas: technical support to assist them in using technology, guided support to remind them to use myStrength and practice skills they had learned, and social support to enable them to connect with others through the program. Furthermore, participants reported that social connections was the most important aspect of the program and that they were mainly motivated to participate in the program because it was recommended to them by trusted others such as a community partner or because they believed it could potentially help others.

Conclusions

Our findings can be used to inform the design of future digital mental health programs for older adults who may have unique support needs in terms of dedicated technical support and ongoing guided support to use technology and social support to increase social connectedness.

Published: November 2022

Aim: Modified versions of the Stroop task have been used in various kinds of clinical conditions. The aim of this study was to develop a Sexual Stroop Task.Method: This study consists of two phases. First phase included designing the sexual Stroop task after searching and selecting Persian sexual and neutral words, and the second phase was related to the pilot study. For finding Persian sexual words, we used four different methods but for neutral words we used the words used in other Stroop studies. Then, we came up with 2 general categories as neutral and sexual words which were randomly specified as green and red colors. The developed computerized version of the Sexual Stroop Task was run on 69 participants as a pilot study. Results: Participants (N=69) had longer response times for words related to sex in comparison to neutral words. And the total time which was spent on sexual words was more than the total time for neutral words. The percentage of the correct neutral words was also higher than correct neutral words.Conclusion: This preliminary study presented a new version of emotional Stoop test that seems to be a promising instrument to study the neuropsychological aspects of sexuality.

Published: November 2022

Teaching and the way of teaching undergo constant changes. Educational games can be great allies in the teaching-learning process, but each one of them has a specific application, which is an important factor in choosing a material for use in the classroom. In Science and Physics teaching, one of the great difficulties encountered by Elementary and High School students comes from the use of equations, and there are few educational games in these directions. In this work, an educational game called Physical-Equation Search is proposed, which is based on the word search. Its purpose is the formation of equations about certain content. It is formed by a table with quantities and mathematical symbols, with sequences that can be given horizontally, vertically or transversally, being simple to make and with easy to understand rules, and can even be reused in various contents. The Physical-Equation Search is a tool to help develop memory and critical thinking about equations, in addition to creating situations that deviate from the traditional method when using play as a didactic device.

The Program was analyzed in the municipalities of Juazeiro/BA and Petrolina/PE, in the period from 2016 to 2021, demonstrating the amount decentralized by FNDE and applied in family farming during this period. This is a quali-quantitative, exploratory, bibliographic, and documentary research. The research findings show the application of resources in family farming by municipalities in the research period, improving the income of producers participating in the program.
El problema mente-cuerpo en las Fuerzas vivas de Kant y en su ambiente intelectual: un enfoque desde la historia intelectual
Authors: Mendoza Gurrola Paulo Sergio
Published: November 2022

Esta contribución examina la solución al problema mente-cuerpo que Kant formula en el marco de su primera explicación causal. Se analiza tanto el planteamiento metafísico como la solución interaccionista de Kant a este problema en su obra sobre las “fuerzas vivas” y, mediante orientaciones metodológicas de la historia intelectual, se contrastan con los planteamientos y soluciones de dos pensadores que influyeron en la formación del pensamiento kantiano: Marquardt y Knutzen, exponentes de algunas de las principales doctrinas causales de la época como la de la armonía preestablecida y el influjo físico. En un sentido, la solución kantiana se plantea como una vía intermedia entre estas dos doctrinas y, en otro, como una postura crítica frente a ambas.

Abstract: Motorcycles are widely used around the world particularly in INDIA. The gear shifting system of the motor-cycle is conventionally manual. This report covers development of an indigenous gear shifting /changing system for the standard motorcycle. By this system the manual mechanical gear- shifting will remain unchanged because an additional electromechanical system is placed on the top of the lever to shift the gear and automatically control the clutch. So the system has both the option manual as well as automatic. The system uses low cost microcontrollers to make the accurate decision for shifting the gear up and down by observing the speed, and it controls the clutch transmission where necessary. The complete hardware and software has been tested and the functioning of the automatic gear shifting system is verified. System is flexible and can be used with any motorcycle ranging from 50 to 200 cc. General Terms Automation.

Published: November 2022

Abstract: Today, we can easily say that there is no limit to the size of the data that exists in the real world-it can be in tens, hundreds, thousands, billions or even trillions of dimensions. However, not all dimensions are vital or relevant for a more detailed analysis. The key objective of educational data mining is to analyze educational data to solve educational and research problems. Our research in this paper focuses primarily on identifying relevant characteristics that can help determine the academic performance of students. The selection of features carried out as data preprocessing techniques keeping in mind the key idea to eliminate irrelevant and redundant features and thus selecting the optimal characteristics that can improve the overall accuracy of the model. The characteristics selected through the selection of functions can help to predict the academic performance of the student in several colleges and universities, which is one of the most imperative contemplations by interested parties to build and maintain a quality system. Although there are several studies that determine the factors that affect the academic performance of students, there is still a gap in existing research that focuses on the psychological factors of a student. The document is structured as follows. Section two contains a brief explanation about the related work in this field. In section three, we have discussed the adopted methodology that presents the data set, the feature selection algorithms, and the characteristic evaluation approach. Section four presents the configuration and experimental results and section five focuses on the conclusion and future scope.

Authors: Chang Dongni , Chen Wanming , Li Megan Yuan , Tai Xiujun , Xu Qian
Published: November 2022

We investigated the influence of negative family events, classified as familymember-based events and property-based events, on Chinese farmers' entrepreneurship. In addition, borrowing insights from conservation of resources theory, we tested the moderating role of socioeconomic status
in the relationships between these two types of negative family events and farmers' entrepreneurial behavior. We used data collected from 2,513 farmer households in Jiangsu Province, China, to show family-member-based negative events had a significant negative association with farmers' entrepreneurship,
whereas property-based negative events had a significant positive association with farmers' entrepreneurship. Moreover, socioeconomic status weakened the negative impact of family-member-based negative events on farmers' entrepreneurship and enhanced the positive impact of property-based negative
events on farmers' entrepreneurship. Our research contributes to the literature on farmers' entrepreneurship by incorporating the role of negative family events. Farmer entrepreneurs should take into consideration the influence of different family-based events.

Objective: The purpose of this case study was to report the symptom improvement effect of integrative Korean medicine treatment based on Pyongsim Solution: Cheonwangbosim-dan in a patient with variant angina and asthma symptoms.Methods: This 68-year-old male patient was treated with Pyongsim Solution, Gamihyangsayukgunja-tang, Gwakhyangjunggi-san, acupuncture, pharmacopuncture, and cupping therapy for 24 days. The European Quality of Life-5 Dimensions-5 Levels profile, Numerical Rating Scale score, and pulse rate per minute were measured on admission, at two weeks of hospitalization, and upon discharge to assess the clinical outcomes.Results: After treatment, the “mobility" dimension profile of the European Quality of Life-5 Dimensions-5 Levels changed from 1 to 1, “self-care" changed from 1 to 1, “usual activity" changed from 3 to 2, “pain/discomfort" changed from 4 to 3, and “anxiety/depression" changed from 3 to 2. The Numerical Rating Scale score for chest pain decreased from 7 to 5, chest tightness decreased from 6 to 4, sleep disturbance decreased from 6 to 3, polydipsia decreased from 5 to 3, and stomach discomfort decreased from 5 to 3. All the profiles of these five dimensions were unchanged for 11 days in the period between the two weeks of hospitalization and discharge. There were also no changes in the profiles of either “mobility” or “self-care” throughout the entire 24-day hospitalization period.Conclusion: This case report shows that integrative Korean medicine treatment based on Pyongsim Solution can improve the symptoms of patients with variant angina and mild intermittent asthma, suggesting that Pyongsim Solution could be an important herbal medication for treatment.
Dispossession, violence and transformative power: an intersectional approach to evictions
Authors: Lacerda Larissa Gdynia , Santoro Paula Freire , Alho Isabella Berloffa , Brito Gisele Aparecida de Sá , Harkot Marina Kohler
Published: November 2022

The present article takes the following question as its starting point: What does it mean to think about eviction and its consequences based on the narratives of women who have faced these processes? By examining the narratives and thoughts of women who have either undergone eviction or are living under its threat, it is possible to highlight dimensions of the process that may otherwise go unnoticed by analyses that focus on other dimensions, and which do not appraise the characteristics of those being evicted and what this represents in terms of the totality of the phenomenon. By shedding light on the multiplicity of impacts resulting from the eviction processes, it is possible to return to the conceptual notion itself, so that it may be formulated from the bottom up, i.e., from the various experiences that comprise it. Ultimately, what is eviction? What does it mean to live under the threat of losing your home?
Teaching Genres to Advanced Learners
Authors: Tincheva Nelly
Published: November 2022

The paper reflects recent thinking and research on what genre is, what the purposes of teaching genres are, and how genres should be taught. The paper argues a case for the application of prototype theory to teaching genres, especially with a view of teaching genres to advanced learners. To align its method with the objective specified, the paper presents perception-based data from questionnaire responses provided by a study group of 100 University students. Results from a test on both the receptive and productive skills of the respondents in the group are discussed. Final Test results of the experimental group and a control group are contrasted. The general method applied is a quantitative one as it coheres with the basic postulates of Rosch’s experimental prototype theory. The research method applied is experiment. The conclusions drawn from the study’s data corroborate strongly the applicability of the notion of prototypes to genre teaching.
Does Internationalization Promote Multilingualism? A Dutch University Study
Authors: Wilkinson Robert
Published: November 2022

Internationalization has been a central concept in university strategic policy for several decades. Internationalization is often a key factor in both university rankings and accreditation processes. Many universities have recruited extensively students and staff globally as well as offering an international dimension within programmes. The upshot is that many university campuses are both multilingual and multicultural. However, policies to promote internationalization may lead to a context where the instructional language is English only. It is instructive to investigate how key actors perceive internationalization and its effects. Do they think it promotes monolingualism or multilingualism? This paper reports on a study into the attitudes of key staff in two faculties at a Dutch university as well as members of the central administration towards internationalization and language use. The results show that while most see internationalization as an unavoidable necessity, they subtly distance themselves from institutional policy and practice, implying a discrepancy between private and public attitudes. The internationalization policy does not stimulate multilingualism, but strengthens monolingualism. The study concludes that the educational system is missing out on the rich heteroglossic and cultural context afforded by internationalization, and suggests that a looser language policy may yield more elaborated learning outcomes.
Decolonial Gestures in Canada’s Settler State: Contemporary Indigenous Writers Jordan Abel and Leanne Simpson
Authors: Aurylaite Kristina
Published: November 2022

This paper discusses the ways recent texts by two Indigenous Canadian writers, Jordan Abel’s collection of conceptual poetry Un/Inhabited and Leanne Simpson’s short stories and poems Islands of Decolonial Love, engage in what Walter Mignolo terms ‘decolonial gestures’ to expose the workings of contemporary settler colonialism and counter their effects. The theoretical section explains the specificities of settler colonialism that make decolonization in the sense of regaining freedom from the colonizers impossible; it then discusses the possibilities for decolonization that exist in settler countries, particularly those that refer to cultural and artistic practices. The analytical section focuses on the different strategies Abel and Simpson use in their work to enact what Mignolo calls ‘epistemic disobedience.’ Abel resorts to decolonial violence in appropriating selected texts of the genre of the Western and erasing from them to undo their loaded ideological messages. Simpson’s work, marked by explicitly confrontational rhetoric, focuses on Indigenous characters and communities, foregrounding their colonial traumas and the role of traditional knowledge and cultural practices in healing them. The paper argues that the decolonial gestures Abel and Simpson undertake work to reject the mainstream rhetoric of reconciliation, inviting Indigenous people to recognize the workings of settler colonialism and look for ways of extricating from them.
EU Presidency Programmes as a Genre
Authors: Kuzmina Jana
Published: November 2022

Along with acting in political, economic and social arenas of the European Union, Latvia was also honoured to preside over the Council of Europe in 2015. This has resulted in the creation of the network of genres pertinent to this communicative event in both Latvian and English to reflect the discursive practices involved. In this view, the present cross-sectional empirical research aims at exploring the written genre of the European Union presidency programmes as one of fundamental documents to propose a set of tentative activities in various economically and socially significant spheres. The theoretical framework for analysis involved the fundamental principles of institutional discourse and the tenets of English for Specific Purposes and New Rhetoric Genre Schools. The exploration of the situational context involves the description of players, the discursive practices and the genre as a textual manifestation of this practice. The results of genre analysis highlight the centrality of the communicative aim and rigid generic macro-structure of a relatively novel genre, which relates to the colony of reporting genres performing the transactional language metafunction. The variation of optional moves occurs as allowed by the communicative aim, which contributes to genre integrity. The topicality of the study is determined by the scarcity of previous research on the genre in question and wide application of research findings.
Problems Students Encounter with Note-Taking in English Medium Instruction
Authors: Malavska Valerija
Published: November 2022

The present article aimed at researching the prerequisites of success­ful note-taking by students, cognitive mechanisms involved in note-taking and the correlation of note-taking with listening skills; it describes both processes taking place while students listen to a lecture and the possible strategies that students use to take notes as well as explores the hindrances that prevent successful recording of the lecture material. It is evident that taking notes does not depend only on students’ abilities to listen and take notes, but directly depends on lecturers’ abilities and skills to deliver the information. The study carried out at Turiba University and St. Petersburg State University of Economics showed to what extent note-taking affects the process of lecture comprehension by students, whether it fosters understanding of the subject as well as to what extent note-taking of B1 – C2 English level students, according to Common European Framework of Reference for Languages (CEFR), depends on students’ abilities to take notes and on lecturers’ skills to deliver information.
Simplified Inverter-Based Generation Model for Protection and Short-Term Stability Studies in Electromagnetic Transient Resolution
Authors: Sánchez Muñoz David , Pérez González Ernesto , Piñeros Juan Fernando , Agudelo Zapata Laura
Published: November 2022

The new dynamics of inverter-based generation (IBG) and the lack of accurate models jeopardize the safety of power systems. Additionally, most of the detailed models for electromagnetic transients (EMT) from manufacturers are black boxes. For this reason, the objective of this work was to propose a generic IBG model in EMT resolution suitable for short-circuit, protections, and short-term voltage stability studies. For this purpose, the model considered different functionalities, such as synchronization in case of unbalanced voltage sags, flexible negative sequence current injection, peak current limitation, dynamic reactive power control, and fault ride-through (FRT). This model allowed grid operators to meet the challenge of performing accurate simulations with high integration of renewable resources in their energy matrix. The model was also based on a voltage-controlled current source in the ATP/EMTP software. The short-circuit response was evaluated in a simulation scenario for different fault events presenting a reliable behavior due to the consideration of technical and regulatory requirements and constraints of IBGs. Finally, the proposed model has a fast initialization and is suitable for simulations with large time steps, making it valuable for EMT simulations in large grids.

Aurintricarboxylic acid as an effective intervention for alveolar epithelial regeneration and tissue repair in emphysematous lung
Authors: Devi Kusum , Moharana Baisakhi
Published: November 2022

Background and purpose: Chronic obstructive pulmonary disease (COPD) is
a global health burden leading to significant morbidity and mortality
worldwide. CS exposure is a crucial driver to various progressive lung
diseases including COPD and there is an unmet need of potential
therapeutics. The present study examined to decipher the therapeutic
role of TWEAK/Fn14 selective inhibitor aurintricarboxylic acid in COPD
pathogenesis. Experimental approach: In vitro alveolar type II cells and
macrophages were stimulated with cigarette smoke extract (CSE) followed
by aurintricarboxylic acid (ATA) treatment. In vivo, rats were injected
with CSE intraperitoneally twice a week for 16 weeks followed by ATA
(10mg/kg) treatment for 4 weeks. Key results: Increased ROS generation,
mitochondrial dysfunction in alveolar type II cells and nuclear
translocation of NF-κB/p65 in macrophages were abrogated after ATA
treatment. In vivo, lung inflammation induced by CSE followed by ATA
treatment mitigated respiratory function impairment, immune cell
infiltration, emphysema associated morphometric parameters and oxidative
stress status. MALDI assessment of rat serum showed decreased CRP and
related inflammatory proteins. In addition, ATA inhibited up-regulation
of EMT related proteins including vimentin, α-SMA, and downstream
transcription factor Snail via inhibition of β-catenin/wnt3a pathway.
Furthermore, ATA reduced CSE-induced inflammatory makers including
TNF-α, NF-κB and MAP kinases including p-p38, p-ERK1/2 and p-JNK in
vitro and in vivo. Cumulatively, ATA enhanced lung regeneration and
tissue repair by diminishing the inflammation and EMT transition. Hence,
ATA can be a novel therapeutic candidate to reduce COPD associated
pathological events and promote regeneration.
Orthodromic Reciprocating Tachycardia Relying on Aberrant Conduction: Need for a Lager Circuit
Authors: Xiong Nanqing , Gu Wentao , Li Jian , Luo Xinping
Published: November 2022

Background Aberrant conduction during orthodromic reciprocating
tachycardia (ORT) can prolong the ventriculo-atrial conduction time,
which is found essential for the reentry in certain situations.
Materials and Methods We searched for ORT cases relying on
aberrancy from 220 cases in our center. Results 3 patients showed
the phenomenon of aberrancy-dependent ORT. All accessory pathways were
located at anterolateral regions of atrioventricular annulus. None of
them had baseline bundle branch block. Creating functional bundle branch
block was necessary to induce the tachycardias. In 2 cases, termination
directly associated with resolution of aberration was observed. While in
the other case, reentry required both interventricular block and slow
pathway conduction. Conclusions We conclude that extra
transseptal time caused by aberrancy can be an integral part of ORT,
which can explain the infrequent or late onset and unsustainable
episodes of ORT in certain patients and is useful in understanding the
circuit and localizing the pathway.
Addressing adherence to guidelines on prevention of acute chemotherapy induced nausea and vomiting in pediatric patients
Authors: Kacar Marija , MacDonald Paula , Gibson Paul
Published: November 2022

Background: Chemotherapy induced nausea and vomiting (CINV) is
a distressing adverse effect in children receiving cancer treatment.
There are evidence-based pediatric clinical practice guidelines (CPG) on
chemotherapy emetogenicity and acute CINV prevention, but adherence to
these guidelines is low. Procedure: A quality improvement-based
study was conducted at McMaster Children’s Hospital. The SMART aim was
to increase adherence to guidelines on prevention of acute CINV in
hospitalized patients receiving high (HEC) and moderately (MEC)
emetogenic chemotherapy from baseline 25% to >70% by June
2021. Barriers were identified by process mapping and a series of
interventions were implemented. Results: Guideline adherence
(GA) was assessed in 270 inpatient chemotherapy administrations (HEC,
MEC). Data was collected on 131 charts pre-interventions and 139 charts
post-interventions. Interventions included education, addition of
guideline recommended anti-emetics to the inpatient formulary and
implementation of a standardized CPG tool. Initial rates of total CINV
GA were 25%, which improved to 72% post-intervention (p
<0.001). In subgroup analysis, GA in the MEC group improved
from 13% to 34% (p=0.015), and in the HEC group from 32% to 93%
(p<0.001). The most common reason for non-adherence in the HEC
group was failure to use aprepitant as anti-emetic, and in MEC was
option for ondansetron monotherapy prophylaxis. Conclusion:
Using quality improvement methodology, barriers to guideline adherence
were identified and interventions implemented. Guideline adherence for
prevention of CINV improved, particularly in the HEC group but less for
the MEC group. Future steps will include sustainability of interventions
and addressing adherence in the MEC group.

Background：Asthma control level is much lower in children.
This study aimed to determine the role of small airway function in
predicting asthma control in preschool children. Method: In
this retrospective cohort study, we enrolled preschool children who
initially diagnosed with asthma and followed up 2 to 3 months by
pediatric pulmonary physicians. Clinical history and lung function
results were collected. Multivariable regression model was applied to
determine risk factors in predicting poor asthma control.
Results: The cohort study was comprised of 219 preschool
children. Sixty-nine of them (31.5%) had poor asthma control. Poor
adherence (14.5% vs 6.0%, p=0.038) and severe airway
hyperresponsiveness (AHR) (20.6% vs 1.6%, p＜0.05) were
more common in poor controlled group. Baseline FEV %
(94.5 vs 101.4, p=0.001), FEF50% (66.1 vs 86.0,
p＜0.001), FEF75% (60.9 vs 75.3, p=0.001),
FEF25-75% (70.9 vs 86.0, p＜0.001) were significantly
lower in poor controlled patients than those of well controlled group.
While, FVC% was similar between the two groups (92.4 vs 96.7,
p=0.093). Multivariable regression models showed severe AHR (OR
9.500, 95%CI 1.404-64.000, p=0.020), lower baseline FEF50% (OR
0.972, 95%CI 0.950-0.994, p=0.012) were significantly associated
with short-term poor asthma control (AUC, 0.740, 95%CI 0.661-0.818).
Conclusion: Preschool asthma children with severe AHR and
decreased FEF50 were at risk of poor asthma control in next 2 to 3
months.
Species composition of shoreline wolf spider communities vary with salinity but their diets vary with wrack inflow

Wolf spiders are typically the most common group of arthropod predators
on both lake and marine shorelines, because of the high prey
availability in these habitats. However, shores are also harsh
environments due to flooding and, in proximity to marine waters, to
toxic salinity levels. Here, we describe the spider community, prey
availabilities and spider diets between shoreline sites with different
salinities, albeit with comparatively small differences (5 vs. 7‰).
Despite the small environmental differences, spider communities between
low and higher saline sites showed an almost complete species turnover.
At the same time, differences in prey availability or spider gut
contents did not match changes in spider species composition but rather
changed with habitat characteristics within region, where spiders
collected at sites with thick wrack beds had a different diet than sites
with little wrack. These data suggest that shifts in spider communities
are due to habitat characteristics rather than prey availabilities, and
the most likely candidate restricting species in high salinity would be
saline sensitivity. At the same time, species absences from low-saline
habitats remain unresolved.
A review on QST–FST comparisons of seed plants: Insights for conservation

Published: November 2022

Increased access to genome-wide data provides new opportunities for
plant conservation. However, information on neutral genetic diversity in
a small number of marker loci can still be valuable because genomic data
are not available to most rare plant species. In the hope of bridging
the gap between conservation science and practice, we outline how
conservation practitioners can more efficiently employ population
genetic information in plant conservation. We first review the current
knowledge about the within-population genetic variation and
among-population differentiation in neutral genetic variation (NGV) and
adaptive genetic variation (AGV) in seed plants. We then introduce the
estimates of among-population genetic differentiation in quantitative
traits (Q) and neutral markers
(F) to plant biology and summarize conservation
applications derived from
Q–F comparisons,
particularly on how to capture most AGV and NGV on both in-situ and
ex-situ programs. Based on a review of published studies, we found that,
on average, two and four populations would be needed for woody
perennials (n = 18) to capture 99% of neutral and adaptive
genetic variation, respectively, whereas four populations would be
needed in case of herbaceous perennials (n = 14). On average,
Q is about 3.6, 1.5, and 1.1 times greater than
F in woody plants, annuals, and herbaceous
perennials, respectively. We suggest using maximum
Q rather than average
Q among trait comparisons. Hence, conservation
and management policies or suggestions based solely on inference on
F could be misleading, particularly in woody
species. We recommend conservation managers and practitioners consider
this when formulating further conservation and restoration plans for
plant species, and for woody species in particular.
Target Tracking Algorithm Based on Improved Probabilistic Data Association
Authors: Huang Xiaojie , Zhang Jiaguo
Published: November 2022

When tracking a single maneuvering target in clutter environment, when
the number of effective measurements within the detection threshold is
small, it usually has a greater and more obvious impact on target
tracking results. If the observation data error is large at this time,
the tracking position and speed error will be larger. To solve this
problem, a target tracking algorithm based on improved probabilistic
data association is proposed in this paper. By dynamically adjusting the
detection threshold, the effective quantity within the detection
threshold of each frame is basically stable. Simulation results show
that the improved algorithm is more accurate in location and speed than
the traditional probabilistic data association method, and the
availability and effectiveness of the algorithm are verified.

Published: November 2022

The enzyme β-mannanase is widely used in industrial applications. In
this study, we heterologously expressed a mannanase (Anman) strain from
Aspergillus niger CBS513.88 in Pichia pastoris and found
that it had the highest activity at pH 3.0 and 72.5°C with a molecular
weight of approximately 47 kDa. The wild-type mannanase Anman remains
stable below 65°C but inactivates rapidly at 70°C. To further improve
the thermostability of Anman, we screened multiple mutation sites using
B-factor and Gibbs unfolding free energy change, and then combined with
multiple sequence alignment and consensus mutation to generate five
excellent single-point mutants, the thermostability of combined mutant
mut5 (E15C/S65P/A84P/A195P/T298P) was 70% increased than wild type
Amman at 70℃, and the melting temperature ( T)
and half-life ( t) values were increased by
2°C and 7.8 folds, respectively. Molecular dynamics simulation showed
reduced flexibility and additional chemical bonds in the region near the
mutation site. These results indicate that we obtained a mannanase
mutant that is more suitable for industrial application, and also
confirm that a combination of rational and semi-rational techniques is
helpful for screening mutant sites.
