Dissolution kinetics of cellulose in ionic solvents by polarized light microscopy
Authors: Villar Lorena , Pita Marta , Paez Javier , Sánchez Pablo B. 
Published: January 2023

AbstractAiming to increase the scarce information available on the kinetics of cellulose dissolution, we have applied an image-assisted technique based on the luminance evolution as cellulose dissolves to study this process under different experimental conditions. This protocol was validated via direct determination of the cellulose dissolved. In all cases datapoints were linearly fitted assuming a pseudo-zero order reaction which facilitates the comparison between datasets. To study the solvent effect we have used three ionic liquids with large basicity and found significantly different rates of dissolution, from faster to slower: [C$$_2$$

Im][DEP]. Solvatochromic parameters and viscosity of the solvent media were determined and the latter was identified as a key factor slowing the process as it reduces ionic mobility. The weight of viscosity was estimated by removing the viscosity effect with a tuned solvent media doped with DMSO. Activation energy was 70% lower at constant viscosity. On the substrate side, particle size is the main factor affecting the dissolution rate. All samples were milled to homogenise the starting material and minimise the distortions caused by the size distribution. After, dissolution of three cellulose substrates under the same experimental conditions was analysed. Dissolution of natural fibers took twice as long as dissolving pulp which dissolves slower than lyocell fibers. This trend correlates with the roughness of the samples obtained by optical perfilometry which is consistent with the dissolution mechanism proposed in the literature.

Beyond the First Offer: Decoding Negotiation Openings and Their Impact on Economic and Subjective Outcomes
Authors: Lipp Wolfram E. , Smolinski Remigiusz , Kesting Peter 
Published: January 2023

AbstractFirst offers play a significant role in negotiations as they anchor negotiators’ perceptions and influence negotiation outcomes in favor of the first-offer proposer. However, negotiation is a joint decision-making process in which a first offer is typically succeeded by a counteroffer. The impact of a counteroffer has not yet been systematically researched. We propose that a counteroffer influences negotiation outcomes like a first offer. In addition, we conceptualize the “anchor zone” as the distance between the first offer and the counteroffer. We theorize that the anchor zone influences negotiation outcomes because it captures additional information compared to a single offer. To test our hypotheses, we conducted two studies: Study 1 was a vignette study (n = 190) in which participants reacted to a counteroffer that they received based on their first offer as part of a simulated negotiation. Study 2 was an online experiment (n = 212) in which participants negotiated by exchanging offers with no further communication. Our analysis suggests that the counteroffer is a significant predictor of economic outcomes. Thus, it works like a first offer, but with a lower impact. In addition, the anchor zone predicted how far the final agreement was from the first offer. Furthermore, we found that the third offer, the average concessions, and the number of offers mediated the effects of the counteroffer and anchor zone on economic outcomes. Finally, we discovered that a more aggressive counteroffer reduced the subjective value of both negotiators.
Development of phytoplankton of Lake Vesijärvi during recovery from eutrophication

Published: January 2023

AbstractWastewaters discharged to Lake Vesijärvi ruined its recreational value and demanded mitigation measures. In the mid-1970s, the diversion of wastewaters elsewhere reduced epilimnetic total phosphorus concentration by ~ 40% from > 100 mg P m−3 in 5 years, but this was not enough to eliminate cyanobacterial blooms. In 1979–1984, hypolimnetic oxygenation was applied to decrease internal nutrient loading, but pumping warm surface water to the hypolimnion probably intensified gas ebullition from the sediment, carrying nutrients to the epilimnion and intensifying cyanobacterial blooms. Intensive fish removal in 1989–1994 was more successful. Five years of summer trawling removed over three-quarters of roach and smelt stock, and after the two most intensive fishing years, TP and chlorophyll concentrations abruptly decreased by ~ 35%. During subsequent years fish removal continued at ~ 30% intensity and maintained chlorophyll and total nutrient concentrations at a lower level until the end of the study. At the same time, the frequency of cyanobacterial blooms decreased from annual to twice per decade. Larger-scale oxygenation after 2010 no longer resulted in ebullition, and its effect on phytoplankton was indistinguishable from natural variability. Consequently, it was abandoned. The intensity of fish removal needed to maintain the present status of the lake is still awaiting evaluation.
Covering families of triangles
Authors: Cheong Otfried , Devillers Olivier , Glisse Marc , Park Ji-won 
Published: January 2023

AbstractA cover for a family $${{\mathcal {F}}}$$
F
of sets in the plane is a set into which every set in $${{\mathcal {F}}}$$
F
can be isometrically moved. We are interested in the convex cover of smallest area for a given family of triangles. Park and Cheong conjectured that any family of triangles of bounded diameter has a smallest convex cover that is itself a triangle. The conjecture is equivalent to the claim that for every convex set $${{\mathcal {X}}}$$
X
there is a triangle Z whose area is not larger than the area of $${{\mathcal {X}}}$$
X
, such that Z covers the family of triangles contained in $${{\mathcal {X}}}$$
X
. We prove this claim for the case where a diameter of $${{\mathcal {X}}}$$
X
lies on its boundary. We also give a complete characterization of the smallest convex cover for the family of triangles contained in a half-disk, and for the family of triangles contained in a square. In both cases, this cover is a triangle.
Updates on the WHO diagnosis of IDH-mutant glioma
Authors: Reuss David.E. 
Published: January 2023

Abstract
Purpose
The WHO classification of Tumors of the Central Nervous System represents the international standard classification for brain tumors. In 2021 the 5th edition (WHO CNS5) was published, and this review summarizes the changes regarding IDH-mutant gliomas and discusses unsolved issues and future perspectives.

Methods
This review is based on the 5th edition of the WHO Blue Book of CNS tumors (WHO CNS5) and relevant related papers.

Results
Major changes include taxonomy and nomenclature of IDH-mutant gliomas. Essential and desirable criteria for classification were established considering technical developments. For the first time molecular features are not only relevant for the classification of IDH-mutant gliomas but may impact grading as well.

Conclusion
WHO CNS5 classification moves forward towards a classification which is founded on tumor biology and serves clinical needs. The rapidly increasing knowledge on the molecular landscape of IDH-mutant gliomas is expected to further refine classification and grading in the future.
Fictitious Language Games, Otherness, and Philosophy of Education: A View on the Later Wittgenstein
Authors: Zarębski Tomasz 
Published: January 2023

AbstractThe article combines later Wittgenstein’s fictitious language games, along with the forms of life associated with them, with the concept of otherness and places them both within the philosophy of education. The account of otherness overlaps with the view of fictional language games in that the latter deviates from our ordinary, extant uses of language and our Lebensform, and thus can be perceived as extraordinary, unusual, strange, and sometimes nonsensical. The advantages of dealing with such construed preposterousness rely, first, on its leading to a better understanding of our own form of life; second, on its opening a window on the changing of our form of life; third, on its acquainting us with the other. The educational roles of it are presented, first, as being needed at the very beginning of a child’s language learning, when the learner probes the limits of sense and thus enters the domain of otherness; second, as freeing children from the tyranny of adults’ norms and showing the norms that adults accept as absurd; thirdly, as puzzlement that gives an impulse to our thought development, which occurs in contact with the other. Therefore, it is claimed that Wittgenstein’s later philosophy opens perspectives on educational thinking not only in terms of teacher training (Abrichtung) of the learner to follow the rules of existing practices, but also in terms of imagination and critical attitude towards the existing forms of life.
Design of an Application-specific VLIW Vector Processor for ORB Feature Extraction

Published: January 2023

AbstractIn computer-vision feature extraction algorithms, compressing the image into a sparse set of trackable keypoints, empowers navigation-critical systems such as Simultaneous Localization And Mapping (SLAM) in autonomous robots, and also other applications such as augmented reality and 3D reconstruction. Most of those applications are performed in battery-powered gadgets featuring in common a very stringent power-budget. Near-to-sensor computing of feature extraction algorithms allows for several design optimizations. First, the overall on-chip memory requirements can be lessened, and second, the internal data movement can be minimized. This work explores the usage of an Application Specific Instruction Set Processor (ASIP) dedicated to perform feature extraction in a real-time and energy-efficient manner. The ASIP features a Very Long Instruction Word (VLIW) architecture comprising one RV32I RISC-V and three vector slots. The on-chip memory sub-system implements parallel multi-bank memories with near-memory data shuffling to enable single-cycle multi-pattern vector access. Oriented FAST and Rotated BRIEF (ORB) are thoroughly explored to validate the proposed architecture, achieving a throughput of 140 Frames-Per-Second (FPS) for VGA images for one scale, while reducing the number of memory accesses by 2 orders of magnitude as compared to other embedded general-purpose architectures.
Development of an Instrument to Assess Expectations for the Use of Online Gaming, Social Networking Sites, and Online Pornography: the Marburg Internet Use Expectations (MINUS-X) Questionnaire

Published: January 2023

AbstractUser’s expectations contribute to the maintenance of problematic use of online gaming (OG), social networking (SN), and online pornography (OP). Since an instrument to assess use expectations across applications is lacking, this study aimed at developing and testing such a questionnaire. It consists of a general module (GM), which includes expectations relevant to all three applications, and three application-specific modules. A pilot and a validation study were conducted with 2880 German adults. We conducted item analyses, exploratory factor analyses (EFA), exploratory structural equation modelling, and correlation analyses. The EFA revealed six factors for the GM and two factors for each specific module. The GM demonstrated measurement invariance between applications. The instrument showed excellent psychometric properties, indicating its suitability for assessing expectations concerning the use of OG, SN, and OG reliably and validly. It could be helpful for treating patients with problematic use of the applications and investigating the role of the relevant expectations.
Evaluation of the Relative Performance of the Subflattenings Method for Phylogenetic Inference
Authors: Stevenson Joshua , Holland Barbara , Charleston Michael , Sumner Jeremy 
Published: January 2023

AbstractThe algebraic properties offlatteningsandsubflatteningsprovide direct methods for identifying edges in the true phylogeny—and by extension the complete tree—using pattern counts from a sequence alignment. The relatively small number of possible internal edges among a set of taxa (compared to the number of binary trees) makes these methods attractive; however, more could be done to evaluate their effectiveness for inferring phylogenetic trees. This is the case particularly for subflattenings, and the work we present here makes progress in this area. We introduce software for constructing and evaluating subflattenings for splits, utilising a number of methods to make computing subflattenings more tractable. We then present the results of simulations we have performed in order to compare the effectiveness of subflattenings to that of flattenings in terms of split score distributions, and susceptibility to possible biases. We find that subflattenings perform similarly to flattenings in terms of the distribution of split scores on the trees we examined, but may be less affected by bias arising from both split size/balance and long branch attraction. These insights are useful for developing effective algorithms to utilise these tools for the purpose of inferring phylogenetic trees.

AbstractLand cover change (LCC) is a complex and dynamic process influenced by social, economic, and biophysical factors that can cause significant impacts on ecological processes and biodiversity conservation. The assessment of LCC is particularly relevant in a country like Mozambique where livelihood strongly depends on natural resources. In this study, LCC was assessed using a point-based sampling approach through Open Foris Collect Earth (CE), a free and open-source software for land assessment developed by the Food and Agriculture Organization of the United Nations. This study aimed to conduct an LCC assessment using CE for the entire Mozambique, and according to three different land classifications: administrative boundaries (provinces), ecoregions, and protected vs unprotected areas. A set of 23,938 randomly selected plots, with an area of 0.5 hectares, placed on a 4 × 4 km regular grid over the entire country, was assessed using CE. The analysis showed that Mozambique has gone through significant loss of forest (− 1.3 Mha) mainly to the conversion to cropland. Deforestation is not occurring evenly throughout the country with some provinces, such as Nampula and Zambezia, characterized by higher rates than others, such as Gaza and Niassa. This result can be explained considering a combination of ecological and socio-economic factors, as well as the conservative role played by the protected areas. Our study confirmed that LCC is a complex phenomenon, and the augmented visual interpretation methodology can effectively complement and integrate the LCC analyses conducted using the traditional wall-to-wall mapping to support national land assessment and forest inventories and provide training data for environmental modeling.
Supporting Remote Social Robot Design Collaboration with Online Canvases: Lessons Learned from Facilitators’ and Participants’ Experiences
Authors: Ahtinen Aino , Kaipainen Kirsikka , Jarske Salla , Väänänen Kaisa 
Published: January 2023

AbstractSocial robot design projects typically involve multidisciplinary teamwork and collaboration, adopt a Human-Centred Design (HCD) approach, and deal with physical (tangible) objects, i.e., robots. HCD takes a human to the centre point of the design process. A typical activity in HCD are design workshops where a facilitator is needed to guide and moderate the task-related and interactional activities throughout the session. Facilitation is also usually needed in longer-term design projects or courses to guide participants through the different phases of design during several sessions. Recently, due to the COVID-19 pandemic, most design activities including social robot design were rapidly transferred to online mode. Designing for tangible objects is challenging in online settings because the interaction experience with a physical object is hard to demonstrate online. In this article, we report how we harnessed online canvases to support both short-term social robot design workshops and a long-term design course. Based on participants’ feedback and facilitators’ experiences, we report lessons learned from utilizing collaborative design canvases for creative social robot design projects that specifically focus on early stages and concept ideation. We propose practical guidelines for canvas-based online facilitation focusing on creative design workshops and projects. In addition, we discuss the lessons learned concerning social robot design activities taking place in online mode. To respond to the challenges of designing tangible robots in a fully online mode, we suggest a Hybrid Robotic Design Model (HRDM), where the participants work in contact with facilitators, other participants and robots at specific points, while the other phases are conducted online.
Perspectives of Maternal Mindful Parenting: Development and Initial Validation of the Mindful Parenting Inventories for Parents (MPIP) and Children (MPIC)
Authors: Acet Pinar , Oliver Bonamy R. 
Published: January 2023

Abstract
Objectives
Mindful parenting and its association with children’s socio-emotional development has garnered increasing research interest in recent years, but child perspectives are little understood. Here, we introduce the development and initial validation of parallel parent- and child-reported inventories—the Mindful Parenting Inventories for Parents (MPIP) and Children (MPIC)—that aim to measure parent and child perspectives of mindful parenting, respectively.

Method
The inventories consist of 18 items comprising 4 mindful parenting subscales (Self-Regulation in Parenting, Acceptance and Compassion towards Child, Being in the Moment with Child, Awareness of Child). Following initial feasibility work, 135 mothers (Mage = 44.50 years, SDage = 5.49 years) and 90 typically developing children (Mage = 13.09 years, SDage = 1.66 years) formed a validation sample in the UK. Partial measurement invariance was supported across reporters.

Results
There were medium-to-large correlations between MPIP and MPIC total scores and subscales, and both demonstrated excellent convergent validity (associations with mothers’ dispositional mindfulness and “traditional” parenting constructs) and concurrent validity (associations with children’s internalising, externalising and prosocial behaviours and mothers’ psychological distress). Furthermore, incremental validity—predictions from MPIP/MPIC to children’s behaviours over and above maternal dispositional mindfulness and traditional parenting—was apparent.

Conclusions
The parallel MPIP and MPIC show promise for assessing mindful parenting from both parent and child perspectives.

After Dinner Rest a While, After Supper Walk a Mile? A Systematic Review with Meta-analysis on the Acute Postprandial Glycemic Response to Exercise Before and After Meal Ingestion in Healthy Subjects and Patients with Impaired Glucose Tolerance
Authors: Engeroff Tobias , Groneberg David A. , Wilke Jan 
Published: January 2023

Abstract
Background
The most effective way to cope with high blood sugar spikes is to engage in physical activity in temporal proximity to food intake. However, so far, it is unclear as to whether there is an optimal time for physical activity around food intake.

Objectives
We aimed to identify the impact of pre- and post-meal exercise on postprandial glucose excursions in humans with and without type 2 diabetes mellitus.

Methods
We conducted a systematic review with meta-analysis, PROSPERO registration number: CRD42022324070. We screened MEDLINE/PubMed, Cochrane/CINAHL/EMBASE, and Web of Knowledge until 1 May, 2022. We used the risk of bias rating with the crossover extension of the Cochrane risk of bias assessment tool II. Standardized mean differences (SMDs, Hedges’ g) with 95% confidence intervals (CIs) were calculated as pooled effect estimates of a random-effects meta-analysis. Eligibility criteria included three-armed randomized controlled trials comparing the acute effects of pre- and post-meal exercise to a no-exercise control in humans.

Results
Eight randomized controlled trials (crossover trials, high risk of bias) with 30 interventions in 116 participants (47 diagnosed with type 2 diabetes, 69 without type 2 diabetes) were eligible. Exercise after meal ingestion (real food or meal replacement drinks) led to a reduction in postprandial glucose excursions compared with exercise before eating (15 effect sizes; SMD = 0.47 [95% CI 0.23, 0.70]) and an inactive control condition (15 effect sizes; SMD = 0.55 [95% CI 0.34, 0.75]. Pre-meal exercise did not lead to significantly lower postprandial glucose compared to an inactive control (15 effect sizes; SMD =  − 0.13 [95% CI − 0.42, 0.17]). The time between meal and exercise (estimate =  − 0.0151; standard error = 0.00473; Z =  − 3.19; p = 0.001; 95% CI − 0.024, − 0.006) had a moderating influence on postprandial glucose excursions.

Conclusions
Exercise, i.e., walking, has a greater acute beneficial impact on postprandial hyperglycemia when undertaken as soon as possible after a meal rather than after a longer interval or before eating.
