A behavioural investigation of the substitution phenomenon between tax-sheltered savings plans
Authors: Berger Leslie , Farrar Jonathan , Zhang Lu , Andrejkow Joanna 
Published: May 2023

Abstract
We provide behavioral insights into the economic substitution phenomenon among front-loaded and back-loaded tax-sheltered savings plans. We conduct three behavioral studies with adult Canadian participants to show experimentally that substitution can occur and to explain why substitution can occur. The first study shows that participants transfer savings from a front-loaded plan to a back-loaded plan when the latter becomes available, consistent with a substitution effect. The second study examines how participants trade-off two unique features of back-loaded and front-loaded savings plans. Our results indicate that participants favor the back-loaded tax feature and a variable contribution limit (offered in a front-loaded plan). As participants prefer one feature from each type of plan, this finding can help explain why substitution occurs. The third study provides participants a categorization task with various household budgeting items, including savings items. Results show that 68.1% of participants categorize multiple tax-sheltered savings plans in the same mental account, again consistent with a substitution effect under a budget constraint. As both tax-sheltered savings plans in Canada are used for different purposes, this finding shows that participants tend not to distinguish between the purpose of saving in each account, consistent with a substitution phenomenon.

AbstractLarge carnivores such as the jaguarPanthera oncaare particularly susceptible to population decline and local extinction as a result of habitat loss. Here we report on the long-term monitoring of a local jaguar population in a mixed land-use area in the eastern lowlands of Bolivia from March 2017 to December 2019. We recorded 15 jaguar individuals and four reproduction events (five offspring from three females), suggesting that our study area harbours a resident breeding population. Seven iterations of spatially explicit capture–recapture models provided density estimates of 1.32–3.57 jaguars per 100 km2. Jaguar capture rates were highest in forested areas, with few to no jaguar captures in pastures used for livestock. Massive deforestation after the survey period reduced the proportion of dense forest cover by 33%, shrinking the availability of suitable jaguar habitat and placing the resident jaguar population at risk. We use the jaguar as an indicator species to highlight the threat of habitat destruction in the Chiquitano region and we emphasize the importance of intact forest patches for jaguar conservation.
Life after life: Mullā Ṣadrā on death and immortality
Authors: Faruque Muhammad U. 
Published: May 2023

AbstractThe purpose of this article is twofold: first, I will reconstruct Mullā Ṣadrā's complex arguments for the soul's immortality based on its immaterial nature. Second and finally, I will briefly probe and assess various epistemological and metaphysical objections against Ṣadrā's immaterialist conception of the soul. Ṣadrā contends that our bodily death marks an awakening to the reality of our consciousness on the plane of the imaginal realm (the imaginal world is an isthmus between the sensible world and the world of intelligible forms). For Ṣadrā, ‘death’ does not mark an end or discontinuity in human consciousness, rather it signifies an awakening to a new mode of existence in which the soul, having once been the active principle controlling the actions of the physical body, now manifests itself as the passive recipient of the form given to it by its imaginal reality – a reality shaped by the actions it had performed in its earthly, embodied state. Thus, death is seen as the passage of the soul from the sensible to the imaginal world, until the soul unites with the intelligible world (ʿālam al-ʿaql).
Global Maps of Equatorial Plasma Bubbles Depletions Based on FORMOSAT‐7/COSMIC‐2 Ion Velocity Meter Plasma Density Observations
Authors: Zakharenkova Irina , Cherniak Iurii , Braun John J. , Wu Qian 
Published: May 2023

AbstractFORMOSAT‐7/COSMIC‐2 is the largest equatorial multi‐satellite constellation of six full‐size satellites to study the equatorial ionosphere. Each satellite is equipped by an ion velocity meter (IVM) instrument to provide high rate in situ plasma density observations along the low‐inclined satellite orbits at ∼530–550 km altitude. Six satellites provide an unprecedented dense coverage of the entire equatorial region around the globe and allow reliable detection of equatorial plasma bubbles (EPBs) and plasma density irregularities at different local times/longitudinal sectors simultaneously. We present a method for detection of EPBs in FORMOSAT‐7/COSMIC‐2 in situ plasma density data and construction of the global maps of EPB geolocations. The results in the form of time series and IVM‐based global Bubble Maps have a great potential for both near real‐time monitoring of space weather conditions and long‐term statistical analysis of EPB occurrence in regional or global scales. We present first FORMOSAT‐7/COSMIC‐2 derived climatological characteristics of the post‐sunset and post‐midnight EPBs occurrence probability and their apex altitudes during a period of low solar activity. Also, we demonstrate the good performance of the FORMOSAT‐7/COSMIC‐2 IVM‐based Bubble Maps when compared to optical images and ground‐based ionosonde observations.
Can One Predict Coronal Mass Ejection Arrival Times With Thirty‐Minute Accuracy?
Authors: Tóth Gábor , van der Holst Bart , Manchester Ward 
Published: May 2023

AbstractJ. Schmidt and Cairns (2019, https://doi.org/10.48550/arXiv.1905.08961) have recently claimed that they can predict Coronal Mass Ejection (CME) arrival times with an accuracy of 0.9 ± 1.9 hr for four separate events. They also stated that the accuracy gets better with increased grid resolution. Here, we show that combining their results with the Richardson extrapolation (Richardson & Gaunt, 1927, https://doi.org/10.1098/rsta.1927.0008), which is a standard technique in computational fluid dynamics, could predict the CME arrival time with 0.2 ± 0.26 hr accuracy. The CME arrival time errors of this model would lie in a 95% confidence interval [−0.21, 0.61] hr. We also show that the probability of getting these accurate arrival time predictions with a model with a standard deviation exceeding 2 hr is less than 0.1%, indicating that these results cannot be due to random chance. This unprecedented accuracy is about 20 times better than the current state‐of‐the‐art prediction of CME arrival times with an average error of about ±10 hr. Based on our analysis there are only two possibilities: the results shown by J. Schmidt and Cairns (2019, https://doi.org/10.48550/arXiv.1905.08961) were not obtained from reproducible numerical simulations, or their method combined by the Richardson extrapolation is in fact providing CME arrival times with half an hour accuracy. We believe that this latter interpretation is very unlikely to hold true. We also discuss how the peer‐review process apparently failed to even question the validity of the results presented by J. Schmidt and Cairns (2019, https://doi.org/10.48550/arXiv.1905.08961).
Brain-derived neurotrophic factor measurements in mouse serum and plasma using a sensitive and specific enzyme-linked immunosorbent assay
Authors: Want Andrew , Morgan James E. , Barde Yves-Alain 
Published: May 2023

AbstractThis study is about the quantification and validation of BDNF levels in mouse serum and plasma using a sensitive immunoassay. While BDNF levels are readily detectable in human serum, the functional implications of these measurements are unclear as BDNF released from human blood platelets is the main contributor to the serum levels of BDNF. As mouse platelets do not contain BDNF, this confounding factor is absent in the mouse. Accordingly, BDNF levels in mouse serum and plasma were found to be indistinguishable at 9.92 ± 1.97 pg/mL for serum and 10.58 ± 2.43 pg/mL for plasma (p = 0.473). These levels are approximately a thousand times lower than those measured in human serum and pre-adsorption with anti-BDNF, but not with anti-NGF or anti-NT3 monoclonal antibodies, markedly reduced the BDNF signal. These results open the possibility to explore the relevance of BDNF levels as a biomarker in accessible body fluids using existing mouse models mimicking human pathological conditions.

Published: May 2023

AbstractIt is anticipated that sixth‐generation (6G) systems would present new security challenges while offering improved features and new directions for security in vehicular communication, which may result in the emergence of a new breed of adaptive and context‐aware security protocol. Physical layer security solutions can compete for low‐complexity, low‐delay, low‐footprint, adaptable, extensible, and context‐aware security schemes by leveraging the physical layer and introducing security controls. A novel physical layer security scheme that employs the concept of radio frequency fingerprinting (RF‐FP) for location estimation is proposed, wherein the RF‐FP values are collected at different points with in the cell. Then, based on the estimated location, the nearest possible road‐side unit for sending the information signal is located. After this, the effects on secrecy capacity (SC) and secrecy outage probability (SOP) in the presence of multiple eavesdropper per unit time are analysed. It has been shown via simulations that the proposed RF‐FP scheme increases SC by up to 25% for the same signal‐to‐noise ratio (SNR) values as those of the benchmarks, while the SOP tends to decrease by up to 30% as compared to the benchmark scheme for the same SNR value. Thus, the proposed RF‐FP‐based location estimation provides much better results as compared to the existing physical layer security schemes.
Comparative experiments on a new CaCl2-based composite material and zeolite 13X inside a thermochemical heat storage reactor
Authors: Bérut Élise , Outin Jonathan , Ondarts Michel , Lange Hugo , Le Pierrès Nolwenn 
Published: May 2023

Thermal energy storage includes sensible, latent and thermochemical heat storage. The latter is particularly interesting because the heat is stored as a chemical potential, which reduces heat loss in long-term applications. The viability of thermochemical storage systems strongly depends on the energy density of the storage material. The development of high energy density materials is thus essential to achieve compact systems suitable for a wide range of applications.
A new sol-gel composite material is investigated here: it is composed of CaCl2 dispersed within a matrix of silica and PEG-600 polymer. Composite materials containing CaCl2 have the highest storage capacities and seem to be the most promising candidates. The aim is to develop a composite that is both efficient and stable. The suitability of the material depends on the ability of the PEG to stabilise calcium chloride and prevent its deliquescence and leakage. The experimental results are compared to those obtained using zeolite 13X, which is a reference adsorbent material.
The born global and international new venture revisited: An alternative explanation for early and rapid internationalization
Authors: Rumyantseva Maria , Welch Catherine 
Published: May 2023

AbstractWe revisit the empirical origins of a popular research topic: the phenomenon of early and rapid internationalization. By means of a qualitative case study, we re-examine the samples of firms used in two of the seminal studies on ‘born globals’ and ‘international new ventures’. A dominant pattern characterizing both samples, but not reported by the original authors, was that incumbent organizations were involved in the founding of the new ventures. Given this unexpected finding, we empirically investigate how being reproduced from pre-existing organizations affected the internationalization pathways of the new ventures, collecting data that extend beyond the scope and time period examined in the original studies. Our analysis shows how the evolution of the relationship between old and new generations of organizations is critical to explaining how new venture internationalization proceeded. Although the incumbent’s presence prior to foundation enabled early and possibly even rapid internationalization, it was also the source of discontinuity and instability. Based on these findings, we offer a relational perspective on the incumbent’s involvement in founding and internationalizing new ventures. Our study illustrates how applying the methodology of a case study revisit can generate new theoretical insights in existing research fields.
The serial verb construction in Tujia
Authors: Lu Man , Ma Yu , van de Weijer Jeroen 
Published: May 2023

Abstract
This paper presents a comprehensive description of the serial
verb construction (henceforth SVC) in Tujia. It shows that serial verbs or verb
phrases in Tujia are linked by the particle lie
55.
lie
55 does not contribute any semantic content
to the construction, but only functions as a linking particle.
lie
55 is not used for any other purpose in any
other structure. SVCs in Tujia can be classified into two types: non-symmetric
and symmetric, depending on argument sharing. Symmetric SVCs can be further
divided into three types according to how the arguments of the verb are shared:
those which share both agents and patients, those which share only agents and
those which do not share any arguments. SVCs in Tujia can be used to indicate
various types of semantic relations: most frequently this involves
sequentiality, but also action-result, cause-effect, and action-purpose. The use
of a linking particle in SVCs is rarely reported in the existing literature, so
that the present research contributes to the general typology of SVCs.
Unraveling-paired dynamical maps recover the input of quantum channels
Authors: Donvil Brecht , Muratore-Ginanneschi Paolo 
Published: May 2023

Abstract
We explore algebraic and dynamical consequences of unraveling general time-local master equations. We show that the ‘influence martingale’, the paramount ingredient of a recently discovered unraveling framework, pairs any time-local master equation with a one parameter family of Lindblad–Gorini–Kossakowski–Sudarshan master equations. At any instant of time, the variance of the influence martingale provides an upper bound on the Hilbert–Schmidt distance between solutions of paired master equations. Finding the lowest upper bound on the variance of the influence martingale yields an explicit criterion of ‘optimal pairing’. The criterion independently retrieves the measure of isotropic noise necessary for the structural physical approximation of the flow the time-local master equation with a completely positive flow. The optimal pairing also allows us to invoke a general result on linear maps on operators (the ‘commutant representation’) to embed the flow of a general master equation in the off-diagonal corner of a completely positive semi-group which in turn solves a time-local master equation that we explicitly determine. We use the embedding to reverse a completely positive evolution, a quantum channel, to its initial condition thereby providing a protocol to preserve quantum memory against decoherence. We thus arrive at a model of continuous-time error correction by a quantum channel.

Abstract
In recent decades, Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) have become workhorses of molecular imaging. The main drawback of these modalities is that they resort to statistical methods of image reconstruction, as the location of the individual nuclei emitting radiation is not accessible. To remedy this situation, we embarked on a project to introduce a new modality of nuclear medical imaging which exploits the non-collinear angular correlations of nuclear gamma-ray cascades subsequent to beta decays. This modality, if effective, determines the location of each decay nucleus. We have retrofitted the small animal PET assembly of RIKEN-Kobe (Japan) with tungsten+PLA (polylactic acid) collimators. The chosen material is inexpensive, amenable to three-dimensional (3D) printing, and has good photon attenuation properties. We included the collimator geometry in GATE (Geant4 Application for Tomographic Emission) simulations and developed algorithms for image reconstruction with medical isotope candidates viz., 111In and 43K. Our preliminary simulations show that data acquisition with a 2 MBq source for 900 s is sufficient to reproduce the source geometry with high resolution. This report summarizes our progress to date and the plans for the near future.
Continuity of robustness measures in quantum resource theories

Published: May 2023

Abstract
Robustness measures are increasingly prominent resource quantifiers that have been introduced for quantum resource theories such as entanglement and coherence. Despite the generality of these measures, their usefulness is hindered by the fact that some of their mathematical properties remain unclear, especially when the set of resource-free states is non-convex. In this paper, we investigate continuity properties of different robustness functions. We show that their continuity depends on the shape of the set of free states. In particular, we demonstrate that in many cases, star-convexity is sufficient for Lipschitz-continuity of the robustness, and we provide specific examples of sets leading to non-continuous measures. Finally, we illustrate the applicability of our results by defining a robustness of teleportability and of quantum discord.
Synchronization of Arabidopsis flowering time and vegetative growth stage via FT overexpression can reveal inherent heterosis due to heterozygosity in intraspecific hybrids
Authors: Yamaguchi Takafumi , Sugi Naoya , Nojima Yukiko , Entani Tetsuyuki , Shiba Hiroshi 
Published: May 2023

ABSTRACT
Intraspecific hybrids of Arabidopsis sometimes display heterosis. However, allelic variation of flowering repressor genes causes late flowering in F1, which might distort the potential heterosis effect due to prolonged vegetative growth. Here, overexpression of flowering gene FT synchronized flowering and eliminated growth differentials between parental and F1. These findings indicate the possibility of quantitatively demonstrating the inherent heterosis caused by heterozygosity.

Abstract

OBJECTIVES
Total ischaemic time (IT) is considered a limiting factor in lung transplantation. In this retrospective study, we investigate effects of IT and disease burden on outcomes after bilateral lung transplantation.

METHODS
A total of 1298 patients undergoing bilateral lung transplantation between January 2010 and May 2022 (follow-up 100%, median 54 months) were included. Pre-transplant diseases’ severity (recipient body mass index, recipient age, previous lung transplantation, Tacrolimus immunosuppression, preoperative recipient extracorporeal membrane oxygenation support, lung volume reduction) for graft failure was individually calculated and—as IT—categorized. Vice versa adjusted Cox models were calculated. Considering competing risks, we assessed cumulative incidences of airway obstructive complications and chronic lung allograft dysfunction with death as competing risk factors for primary graft dysfunction were assessed by binary logistic regression.

RESULTS
Higher disease burden significantly accelerated chronic lung allograft dysfunction and death occurrence (P &lt; 0.001); IT did not. IT-adjusted disease burden strata showed 50% graft survival differences at 11 years after transplantation (range 24–74%), disease burden-adjusted IT strata 18% for all and 6% (54–60%) among those above 7 h. All significant primary graft dysfunction risk factors were diagnoses related, IT was not significantly important and odds ratios did not increase with IT.

CONCLUSIONS
The eventual graft survival disadvantage that results from an IT between 7 and at least 11 h is negligible in contrast to frequent recipients’ disease-based risk levels.

Abstract
ATRX is a chromatin remodelling ATPase that is involved in transcriptional regulation, DNA damage repair and heterochromatin maintenance. It has been widely studied for its role in ALT-positive cancers, but its role in neurological function remains elusive. Hypomorphic mutations in the X-linked ATRX gene cause a rare form of intellectual disability combined with alpha-thalassemia called ATR-X syndrome in hemizygous males. Clinical features also include facial dysmorphism, microcephaly, short stature, musculoskeletal defects and genital abnormalities. As complete deletion of ATRX in mice results in early embryonic lethality, the field has largely relied on conditional knockout models to assess the role of ATRX in multiple tissues. Given that null alleles are not found in patients, a more patient-relevant model was needed. Here, we have produced and characterized the first patient mutation knock-in model of ATR-X syndrome, carrying the most common causative mutation, R246C. This is one of a cluster of missense mutations located in the chromatin-binding domain and disrupts its function. The knock-in mice recapitulate several aspects of the patient disorder, including craniofacial defects, microcephaly, reduced body size and impaired neurological function. They provide a powerful model for understanding the molecular mechanisms underlying ATR-X syndrome and testing potential therapeutic strategies.
