The post-fire shift of temperate white pine-birch forest to boreal balsam fir forest in eastern Canada: climate-fire implications
Authors: Payette Serge , Frégeau Mathieu , Couillard Pierre-Luc , Laflamme Jason 
Published: April 2023

Extensive 14C dating and botanical identification of charcoal fragments located in the organic surface soil layer and buried in the mineral podzolic solum were used to reconstruct the successional pathways of a balsam fir forest site. The studied forest site developed in a context of continuous fire disturbance over the last 9000 years with at least 26 fires occurring at a mean interval of 330 years. Tree vegetation of the site followed a four-step trajectory consisting of an early-Holocene spruce forest and a late-Holocene mixedwood balsam fir forest. Boreal-like spruce-birch and temperate-like white pine-birch forests dominated the site between 7900 and 5900 cal. B.P. and 5600 and 1275 cal. B.P., respectively. Because all forest types developed repeatedly after fire since early deglaciation, changes in forest composition, in particular the shift of white pine forest to balsam fir forest, and concurrent decline of birch (yellow birch and/or paper birch) and pine populations were most likely related to progressive cooler and wetter conditions from mid- to late Holocene. Fire disturbance on this part of the southern boreal biome has been a continuous, positive regenerative process over the Holocene, allowing the successional turnover of boreal and temperate trees under the influence of climatic change.
Solubility and solvation thermodynamics of l-tryptophan in aqueous methanol solvent mixtures
Authors: Saha Avishek , Mahali Kalachand , Roy Sanjay 
Published: April 2023

This article presents mole fraction solubilities of l-tryptophan in binary aqueous methanol solvent systems and applied them to estimate thermodynamical parameters like transfer Gibbs free energetics and entropies of solutions. The estimated thermodynamic energies were linked with interaction parameters like dipole–dipole interactions, enthalpy due to transfer of l-tryptophan from water to binary water–methanol solvent mixtures. The transfer Gibbs free energetics for chemical interactions and entropies for solvent–solvent interaction were calculated by mathematical relations. The chemical transfer energetics was applied to explain the probable stability of l-tryptophan in the mixed solvents. Many associated thermophysical parameters were also calculated at standard temperature (298.15 K).

Published: April 2023

Unveiling factors that determine abundance and distribution of endangered wildlife species has important implications for their conservation across international boundaries. For instance, the Western Distinct Population (as defined by the U.S. Fish and Wildlife Service) of the yellow-billed cuckoo Coccyzus americanus (Linnaeus, 1758) has disappeared in most of the species’ range across western United States and southwestern Canada but little is known about the conservation status at the southern edge of its breeding distribution in Mexico. To fill this information gap, we estimated abundance and occupancy rates of yellow-billed cuckoos using a standard broadcast call survey protocol. We used Bayesian spatial count models to estimate cuckoo population density at survey sites. We used Bayesian hierarchical models to estimate the effects of geography, climate, and vegetation on occupancy rates while accounting for imperfect detection. Mean cuckoo count per transect for all sites was [Formula: see text] = 9.00 ± 0.45 cuckoos. Overall cuckoo density was [Formula: see text] = 13.18 cuckoos/km2( SD([Formula: see text]) = 5.61 cuckoos/km2). Overall cuckoo occupancy in Sonora was [Formula: see text] = 0.538 (95% credible interval ( ψ) = 0.488–0.600), but showed strong geographic variation. Relatively high occupancy levels suggest yellow-billed cuckoo populations in Sonora may be robust, but they are largely reliant on declining high-tree cover.

Published: April 2023

Abstract

Cellular components of the tumor microenvironment, including myeloid cells, play important roles in the progression of lung adenocarcinoma (LUAD) and its response to therapy. Here, we characterize the function of the ubiquitin ligases Siah1a/2 in regulating the differentiation and activity of alveolar macrophages (AM) and assess the implication of Siah1a/2 control of AMs for carcinogen-induced LUAD. Macrophage-specific genetic ablation of Siah1a/2 promoted accumulation of AMs with an immature phenotype and increased expression of protumorigenic and pro-inflammatory Stat3 and β-catenin gene signatures. Administration of urethane to wild-type mice promoted enrichment of immature-like AMs and lung tumor development, which was enhanced by macrophage-specific Siah1a/2 ablation. The profibrotic gene signature seen in Siah1a/2-ablated immature-like macrophages was associated with increased tumor infiltration of CD14+ myeloid cells and poorer survival of patients with LUAD. Single-cell RNA-seq confirmed the presence of a cluster of immature-like AMs expressing a profibrotic signature in lungs of patients with LUAD, a signature enhanced in smokers. These findings identify Siah1a/2 in AMs as gatekeepers of lung cancer development.

Significance:
The ubiquitin ligases Siah1a/2 control proinflammatory signaling, differentiation, and profibrotic phenotypes of alveolar macrophages to suppress lung carcinogenesis.

Abstract

Background:
Lifestyle habits can impact breast cancer development, but its impact on breast cancer prognosis remains unclear. We investigated associations of post-diagnosis lifestyle with mortality and recurrence in 1,964 women with invasive breast cancer enrolled in the Kaiser Permanente Northern California Pathways Study shortly after diagnosis with lifestyle information at baseline (2005–2013) and the 2-year follow-up.

Methods:
We calculated a post-diagnosis lifestyle score (range, 0–18) based on 9 diet, physical activity, and body weight recommendations from the American Cancer Society/American Society of Clinical Oncology (ACS/ASCO) using follow-up data (body weight also included baseline data); higher scores indicate greater guideline concordance. Similarly, we calculated a pre-diagnosis lifestyle score using baseline data to investigate pre- to post-diagnosis changes. We estimated hazard ratios (HR) and 95% confidence intervals (CI) using Cox proportional hazard models, with follow-up through December 2018 (observing 290 deaths and 176 recurrences).

Results:
The 2-year post-diagnosis lifestyle score was inversely associated with all-cause mortality (ACM; HR per 2-point increase = 0.90; 95% CI, 0.82–0.98), and breast cancer–related mortality (HR, 0.79; 95% CI, 0.67–0.95), but not recurrence. Relative to women who maintained low concordance with recommendations at both time points, women who maintained high concordance had a lower risk of ACM (HR, 0.61, 95% CI, 0.37–1.03). Improved concordance with some specific recommendations (particularly PA) may be associated with a lower hazard of ACM (HRPA, 0.52; 95% CI, 0.35–0.78).

Conclusions:
Results suggest that women with breast cancer may benefit from a post-diagnosis lifestyle aligned with ACS/ASCO guidelines.

Impact:
This information may potentially guide lifestyle recommendations for breast cancer survivors to reduce mortality risk.
Teatralidades e performatividades em contextos necropolíticos
Authors: Diéguez Ileana , Bulhões Marcos 
Published: April 2023

Este texto explora estratégias representacionais desenvolvidas por artistas e pela sociedade civil para interpelar o excessivo uso do poder em regimes patriarcais como o cubano, especialmente a partir dos massivos protestos sociais de 11 de julho de 2021, antecedidos pelos movimentos San Isidro e 27N. Apostamos na potência dos corpos raivosos como resultado da violência exercida sobre as pessoas em regimes de controle totalitário e práticas necropolíticas. A teatralidade do Estado pode ser utilizada para reforçar um sistema panóptico, que intenta subjugar toda forma de dissidência e resistência, do mesmo modo que desenvolve uma performatividade punitiva. Porém, esses mesmos dispositivos são utilizados em atos e gestos de subversão cívica que tornam visíveis a brutalidade dos poderes. Em um enfoque comparativo, são retomadas ações realizadas por artistas em outros contextos de extrema violência, como no México, para visibilizar as formas pelas quais os necropoderes se inscrevem nos corpos. Finalmente, se questionam as possíveis colaborações do silêncio diante dos necropoderes.

Published: April 2023

Background:
Current clinical imaging of thromboembolic diseases often relies on indirect detection of thrombi, which may delay diagnosis and ultimately the institution of beneficial, potentially lifesaving treatment. Therefore, the development of targeting tools that facilitate the rapid, specific, and direct imaging of thrombi using molecular imaging is highly sought after. One potential molecular target is FXIIa (factor XIIa), which initiates the intrinsic coagulation pathway but also activates the kallikrein-kinin system, thereby initiating coagulation and inflammatory/immune responses. As FXII (factor XII) is dispensable for normal hemostasis, its activated form (FXIIa) represents an ideal molecular target for diagnostic and therapeutic approaches, the latter combining diagnosis/identification of thrombi and effective antithrombotic therapy.

Methods:

We conjugated an FXIIa-specific antibody, 3F7, to a near-infrared (NIR) fluorophore and demonstrated binding to FeCl
3
-induced carotid thrombosis with 3-dimensional fluorescence emission computed tomography/computed tomography and 2-dimensional fluorescence imaging. We further demonstrated ex vivo imaging of thromboplastin-induced pulmonary embolism and detection of FXIIa in human thrombi produced in vitro.

Results:

We demonstrated imaging of carotid thrombosis by fluorescence emission computed tomography/computed tomography and measured a significant fold increase in signal between healthy and control vessels from mice injected with 3F7-NIR compared with mice injected with nontargeted probe (
P
=0.002) ex vivo. In a model of pulmonary embolism, we measured increased NIR signal in lungs from mice injected with 3F7-NIR compared with mice injected with nontargeted probe (
P
=0.0008) and healthy lungs from mice injected with 3F7-NIR (
P
=0.021).

Conclusions:
Overall, we demonstrate that FXIIa targeting is highly suitable for the specific detection of venous and arterial thrombi. This approach will allow direct, specific, and early imaging of thrombosis in preclinical imaging modalities and may facilitate monitoring of antithrombotic treatment in vivo.
Exploring Location-Based AR Narrative Design for Historic Site

Published: April 2023

Abstract
The Pickrick Protests is a project exploring the use of Augmented Reality (AR) to recreate a sequence of Civil Rights--era incidents that occurred at the Pickrick restaurant, in Atlanta, over a period of 8 months in 1964–1965. This project gives a connected and chronological narrative of the historic events to form a cohesive experience, with AR projections of computer graphic depictions of the 1960s buildings, and events on the site where they happened. The objective of this project is to make the history of the Civil Rights Movement visible by privileging the perspective of the African Americans who fought for equality. This paper focuses on introducing the narrative design for this location-based AR application (Bowman et al., 1998). We will discuss our approach to creating a meaningful narrative within the technical affordances and environmental constraints of the AR medium and the specific location. The design challenges posed by this project were how to merge the virtual content with the existing, albeit changed, physical space; how to recenter the story on the activists rather than on the segregationist restaurant owner who went on to become a governor of Georgia; and how to direct attention in AR in order to allow interactors to follow a multiepisode narrative, and to focus on the nonviolent activists rather than the aggressive segregationists.
A historical approach to describing the complex behaviour of a large species of carnivorous shark — Case study No. 1: the scalloped hammerhead, Sphyrna lewini
Authors: Klimley Abbott Peter 
Published: April 2023

Abstract
A historical example, case study No. 1, is given illustrating the complexity of interactions between sharks in their natural environment. Scalloped hammerhead sharks, Sphyrna lewini, form polarized schools at offshore islands and seamounts. Females perform a display while inside a school to force smaller individuals to the periphery. The Corkscrew consists of a rapid burst of swimming into a tight looping trajectory, with the shark rotating its torso almost 360° on its longitudinal axis. This conveys a shark’s intent to contact the recipient with a Hit. This is competition for a position at the centre of the school. Males dash into the schools, directing emphatic tail beats to one side with a Torso Thrust, propelling the shark‘s anterior torso laterally, to pair with a dominant female. The pair then moves outside the school to copulate in midwater with the male biting the female’s body and inserting his clasper within her uterus.
From Ashʿarism to waḥda muṭlaqa in Andalusī Sufism: A Survey of Historical Sources on the Shūdhiyya
Authors: Bellver José 
Published: April 2023

Abstract
The Shūdhiyya is a Sufi strand that flourished in the south-east region of al-Andalus, particularly in the area of Murcia, in the late 6th/12th century until the second half of the 7th/13th century. It thus extended from the second half of the Almohad period to the early Naṣrid period. The Shūdhiyya is named after the enigmatic figure, al-Shūdhī (fl. 6th/12th c.), a Sufi saint linked to Tlemcen. Nevertheless, the two main figures of the Shūdhiyya were the theologians and Sufis, Ibn al-Marʾa (d. 611/1214) and Ibn Aḥlā (d. 645/1247). Faced with the advance of Christian forces in the region of Murcia, Shūdhīs relocated to the nascent kingdom of Granada and to the central Islamicate world where, as followers of Ibn Sabʿīn (d. 669/1270), they were known as the Sabʿīniyya. The Shūdhiyya flourished in al-Andalus at roughly the same time that Ibn ʿArabī (d. 638/1240) lived in al-Andalus. And, like Ibn ʿArabī, the Shūdhiyya ultimately came to be known for espousing the unity of existence although in a more radical, absolute way. Even though intellectual Sufism in al-Andalus is mostly associated with Ibn ʿArabī, his actual influence on his contemporaries in al-Andalus was rather scarce as he emigrated in his thirties to the East where he wrote his main works. However, in the field of intellectual Sufism, the Shūdhiyya was far more influential in al-Andalus than Ibn ʿArabī. Nevertheless, since the main representatives of the Andalusī Shūdhiyya did not relocate to the East, their works were not widely disseminated across the eastern and central Islamicate world and, consequently, except for Ibn al-Marʾa, most of their works are not known to be extant. Thus, the main witnesses are biographical and polemical literature. Despite the historical and intellectual relevance of the Shūdhiyya for the social, political and intellectual history of al-Andalus, only Massignon has devoted some attention to this Sufi strand. In this article the available sources on the Shūdhiyya in al-Andalus are surveyed and contextualized.
The Politics of Curating Japonisme
Authors: Ma Scott 
Published: April 2023

Abstract
This article studies the Paris exposition Japonismes 2018, organized by the Japanese government to introduce the European public to the profundity of Japanese culture. It examines the organizational deliberations leading up to the exposition; the curation of individual exhibits held within its ambit; and the cultural politics of ‘Japan expositions’ that began with Japonismes and continue to this day. It argues that the organizers and exhibits in Japonismes make political use of the trope of a timeless, mystical, and animistic Japanese sense of beauty that supposedly unites prehistoric pottery and contemporary comics and animation. This Japanese aesthetic vision claims to provide an alternative to Western norms, thereby promising to resolve contemporary problems, such as anthropocentrism, by influencing Western aesthetics as it had in the late nineteenth century. Japonismes exemplifies how Japanese soft power diplomacy can employ Western tropes about Japan, such as Japonisme, for its economic and nation-branding efforts.

Published: April 2023

AbstractAromatic and aliphatic hydrocarbons (AAHs) are comprised of a variety of gaseous chemicals that may affect human and environmental health. To remove AAHs from air, polytetrafluoroethylene-nickel oxide (PTFE-NiO) composite nanofiber filter mats (NFMs) were synthesized and characterized for their ability to effectively adsorb AAHs. The NiO-nanoparticle-doped mats were fabricated by green electrospinning of PTFE and polyvinyl alcohol (PVA) mixtures added with nickel (II) nitrate hexahydrate in the spinning solution followed by surface heat treatment. FE-SEM FTIR, Raman spectroscopy, sessile drop and Jar methods were applied as characterization techniques. The diameter of the electrospun nanofibers without NiO dopant ranged from 0.34 ± 21.61 to 0.23 ± 10.12 µm, whereas a reduction in diameter of NiO-doped nanofibers was obtained, ranging between pristine to 0.25 ± 24.12 µm and 0.12 ± 85.75 µm with heat treatment. 6% (by weight) NiO-doped PTFE composite NFMs exhibited a high water-contact angle of 120 ± 2.20 degrees; the high hydrophobicity value aided self-cleansing property of NFMs for practical applications. UV adsorption capability for heat-treated PTFE-NiO NFMs was evaluated for three AAHs, and the results showed that 6 wt% NiO adsorbed 1.41, 0.67, and 0.73 µg/mg of toluene, formaldehyde and acetone, respectively. These findings reveal the potential applicability of the prepared filter mats for capturing various AAHs from polluted air.

Published: April 2023

Abstract
Background
Asparagus officinalis L. is a worldwide cultivated vegetable enrichened in both nutrient and steroidal saponins with multiple pharmacological activities. The upstream biosynthetic pathway of steroidal saponins (USSP) for cholesterol (CHOL) synthesis has been studied, while the downstream pathway of steroidal saponins (DSSP) starting from cholesterol and its regulation in asparagus remains unknown.

Results
Metabolomics, Illumina RNAseq, and PacBio IsoSeq strategies were applied to different organs of both cultivated green and purple asparagus to detect the steroidal metabolite profiles & contents and to screen their key genes for biosynthesis and regulation. The results showed that there is a total of 427 compounds, among which 18 steroids were detected with fluctuated concentrations in roots, spears and flowering twigs of two garden asparagus cultivars. The key genes of DSSP include; steroid-16-hydroxylase (S16H), steroid-22-hydroxylase (S22H) and steroid-22-oxidase-16-hydroxylase (S22O-16H), steroid-26-hydroxylase (S26H), steroid-3-β-glycosyltransferase (S3βGT) and furostanol glycoside 26-O-beta-glucosidases (F26GHs) which were correlated with the contents of major steroidal saponins were screened, and the transcriptional factors (TFs) co-expressing with the resulted from synthetic key genes, including zinc fingers (ZFs), MYBs and WRKYs family genes were also screened.

Conclusions
Based on the detected steroidal chemical structures, profiles and contents which correlated to the expressions of screened synthetic and TFs genes, the full steroidal saponin synthetic pathway (SSP) of asparagus, including its key regulation networks was proposed for the first time.
