Asymptotics of eigenvalue sums when some turning points are complex
Authors: Okun Pavel , Burke Kieron 
Published: August 2022

Abstract
Recent work has shown a deep connection between semilocal approximations in density functional theory and the asymptotics of the sum of the Wentzel–Kramers–Brillouin (WKB) semiclassical expansion for the eigenvalues. However, all examples studied to date have potentials with only real classical turning points. But systems with complex turning points generate subdominant (SD) terms beyond those in the WKB series. The simplest case is a pure quartic oscillator. We show how to generalize the asymptotics of eigenvalue sums to include SD contributions to the sums, if they are known for the eigenvalues. These corrections to WKB greatly improve accuracy for eigenvalue sums, especially for many levels. We obtain further improvements to the sums through hyperasymptotics. For the lowest level, our summation method has error below 2 × 10−4. For the sum of the lowest ten levels, our error is less than 10−22. We report all results to many digits and include copious details of the asymptotic expansions and their derivation.
Visions of Refuge: The Central American Exodus and the Floating Ladder
Authors: Schreiber Rebecca M 
Published: August 2022

Abstract
This essay focuses on two performative acts. The first is the fall 2018 caravan, a work of political performance, which involved thousands of Central American migrants/refugees fleeing their countries in response to structural and other forms of violence. These caravaneros (caravaners) traveled collectively through Honduras, Guatemala, and Mexico to protect themselves from being targeted by state and nonstate actors en route to the US–Mexico border. The second performative act, which took place in Tijuana in January 2019, involved an artistic collaboration between Caleb Duarte and a group of caravaneros temporarily residing at El Barretal, a heavily guarded Mexican government-run refugee camp. Together, Duarte and the caravaneros co-authored a sculptural performance, creating a fabric ladder tied to helium balloons, which the wind lifted above the camp. I argue that Floating Ladder enacts how these caravaneros imagine their movement and mobility, as it challenges the regional immigration regime aiming to block migrants/refugees from making asylum claims in the US. Both the fall 2018 caravan and Duarte’s collaborative artwork with caravaneros are political acts by migrants/refugees that entailed the construction of social and political imaginaries beyond the constraints and violence of national borders.

World of Borders: Harsha Walia's Border and Rule: Global Migration, Capitalism, and the Rise of Racist Nationalism
Authors: Watson Jini Kim 
Published: August 2022

Abstract
This essay analyses Harsha Walia’s 2021 book Border and Rule: Global Migration, Capitalism, and the Rise of Racist Nationalism. It discusses the way Walia boldly recasts today’s “migration crisis” less as a problem “at the border,” and more in terms of its enmeshment with the logics of neoliberal capitalism. Deploying a framework of global comparativity and interdisciplinarity—and written in a steady tone of outrage—Walia reads the operations of contemporary border regimes through, on the one hand, global histories of racial exclusions and, on the other, modes of neoliberal labor exploitation. While valuable for its global scope and the synthetic labor of its analyses, Walia’s study devotes less attention to the nature of resistances and solidarities needed to combat the interlocking regimes of bordering, citizenship exclusions, extractive violence, ecofascisms, and renovated racisms. Nevertheless, Walia raises pertinent questions for literary studies about how different disciplines make the figure of the migrant appear or disappear.
Commentary: Passwords and Passage
Authors: Redmond Shana L 
Published: August 2022

Abstract
Drawing into conversation the work of two special issue authors, Redmond continues in exposition of the dangerous contradictions within and inherent failures of the state’s security and citizenship regimes through attention to minoritized testimony and translation. The author of memoir and courtroom or detention witness present as performers of vulnerable narrative projects that are sometimes playful, sometimes grave but always in critical contest, if not combat, with the designs of racial capitalism and exception. In attending to these moments of subversion and illegibility, new opportunities arise for retooling in defense against and circumvention of state procedure and possession.
Resettling Refugee History
Authors: DeGooyer Stephanie 
Published: August 2022

AbstractThis article pursues a longue durée study of the US refugee to resettle, in necessary and generative ways, contemporary interest in the refugee as representative of a current “global crisis” and as inherently tied to the unique violence of the twentieth and twenty-first centuries. It argues that the twentieth century is not the only thinkable or relevant period for a refugee literary history. The colonial construction of “asylum,” the word we refer today as a legal source of political protection for refugees, was in earlier times intertwined with the development of an exclusionary migration regime, vestiges of which continue to govern the reception of migrants today. The very idea of asylum, despite becoming a legal fixture of human rights law in the twentieth century, was never meant to be expansive in the US. How we make sense of this disjuncture is a serious project for literary scholarship invested in refugees and migration.The limbo that many contemporary refugees find themselves in today, in detention camps and other make-shift shelters, is tied to the US’s early fictional conception of itself as a refuge for white European foreigners.

Abstract

Background
Vancomycin (VAN)-associated acute kidney injury (AKI) is increased when VAN is combined with certain beta-lactams (BLs) such as piperacillin-tazobactam (TZP) but has not been evaluated with ceftolozane-tazobactam (C/T). Our aim was to investigate the AKI incidence of VAN in combination with C/T (VAN/C/T) compared with VAN in combination to TZP (VAN-TZP).

Methods
We conducted a multicenter, observational, comparative study across the United States. The primary analysis was a composite outcome of AKI and risk, injury, failure, loss, end stage renal disease; Acute Kidney Injury Network; or VAN-induced nephrotoxicity according to the consensus guidelines. Multivariable logistic regression analysis was conducted to adjust for confounding variables and stratified Kaplan–Meir analysis to assess the time to nephrotoxicity between the 2 groups.

Results
We included VAN/C/T (n = 90) and VAN-TZP (n = 284) at an enrollment ratio of 3:1. The primary outcome occurred in 12.2% vs 25.0% in the VAN-C/T and VAN-TZP groups, respectively (P = .011). After adjusting for confounding variables, VAN-TZP was associated with increased odds of AKI compared with VAN-C/T; with an adjusted odds ratio of 3.308 (95% confidence interval, 1.560–6.993). Results of the stratified Kaplan–Meir analysis with log-rank time-to-nephrotoxicity analysis indicate that time to AKI was significantly shorter among patients who received VAN-TZP (P = .004). Cox proportional hazards analysis demonstrated that TZP was consistent with the primary analysis (P = .001).

Conclusions
Collectively, our results suggest that the AKI is not likely to be related to tazobactam but rather to piperacillin, which is a component in VAN-TZP but not in VAN-C/T.
Effects of Stereotype-Focused Imagined Contact on Young Adults’ Intentions for Intergenerational Interaction
Authors: Fowler Craig , Gasiorek Jessica 
Published: August 2022

Abstract

Objectives
Face-to-face intergenerational contact is associated with more positive attitudes toward older adults. However, such contact can be difficult to achieve, and poor contact experiences can have negative consequences for intergenerational relations. We examined whether mentally simulated intergenerational contact (which is more easily facilitated and controllable) could reduce young adults’ inclinations to avoid intergenerational interactions by increasing their inclusion of the older outgroup in the self (IOS), and by enhancing their stereotypes of older adults’ warmth and competence.

Method
We conducted an online experiment with 373 young adults from the United States. Participants imagined talking with an older adult (aged 70–75 years) in the circumstances intended to make salient either the older adult’s warmth or their competence.

Results
Both manipulations increased young adult participants’ IOS with respect to older adults, which in turn predicted more positive assessments of older adults’ warmth and competence. IOS, along with ratings of warmth and competence, inversely predicted the desire to avoid future interaction with older adults.

Discussion
Findings indicate the viability of a simple and accessible intervention to improve intergenerational relations, which can be tailored to address different goals (e.g., encouraging intergenerational friendships vs. encouraging support for equal rights of older members of the workforce).

Published: August 2022

Abstract

Background
Mortality statistics using a single underlying cause of death (UC) are key health indicators. Rising multimorbidity and chronic disease mean that deaths increasingly involve multiple conditions. However, additional causes reported on death certificates are rarely integrated into mortality indicators, partly due to complexities in data and methods. This study aimed to assess trends and patterns in cause-related mortality in Australia, integrating multiple causes (MC) of death.

Methods
Deaths (n = 1 773 399) in Australia (2006–17) were mapped to 136 ICD-10-based groups and MC indicators applied. Age-standardized cause-related rates (deaths/100 000) based on the UC (ASRUC) were compared with rates based on any mention of the cause (ASRAM) using rate ratios (RR = ASRAM/ASRUC) and to rates based on weighting multiple contributing causes (ASRW).

Results
Deaths involved on average 3.4 causes in 2017; the percentage with &gt;4 causes increased from 20.9 (2006) to 24.4 (2017). Ischaemic heart disease (ASRUC = 73.3, ASRAM = 135.8, ASRW = 63.5), dementia (ASRUC = 51.1, ASRAM = 98.1, ASRW = 52.1) and cerebrovascular diseases (ASRUC = 39.9, ASRAM = 76.7, ASRW = 33.5) ranked as leading causes by all methods. Causes with high RR included hypertension (ASRUC = 2.2, RR = 35.5), atrial fibrillation (ASRUC = 8.0, RR = 6.5) and diabetes (ASRUC = 18.5, RR = 3.5); the corresponding ASRW were 12.5, 12.6 and 24.0, respectively. Renal failure, atrial fibrillation and hypertension ranked among the 10 leading causes by ASRAM and ASRW but not by ASRUC. Practical considerations in working with MC data are discussed.

Conclusions
Despite the similarities in leading causes under the three methods, with integration of MC several preventable diseases emerged as leading causes. MC analyses offer a richer additional perspective for population health monitoring and policy development.
Computer simulation of surgical interventions for the treatment of refractory pulmonary hypertension

Published: August 2022

AbstractThis paper describes computer models of three interventions used for treating refractory pulmonary hypertension (RPH). These procedures create either an atrial septal defect, a ventricular septal defect or, in the case of a Potts shunt, a patent ductus arteriosus. The aim in all three cases is to generate a right-to-left shunt, allowing for either pressure or volume unloading of the right side of the heart in the setting of right ventricular failure, while maintaining cardiac output. These shunts are created, however, at the expense of introducing de-oxygenated blood into the systemic circulation, thereby lowering the systemic arterial oxygen saturation. The models developed in this paper are based on compartmental descriptions of human hemodynamics and oxygen transport. An important parameter included in our models is the cross-sectional area of the surgically created defect. Numerical simulations are performed to compare different interventions and various shunt sizes and to assess their impact on hemodynamic variables and oxygen saturations. We also create a model for exercise and use it to study exercise tolerance in simulated pre-intervention and post-intervention RPH patients.
The Geometry of Polynomial Representations
Authors: Bik Arthur , Draisma Jan , Eggermont Rob H. , Snowden Andrew 
Published: August 2022

AbstractWe define a GL-variety to be an (typically infinite dimensional) algebraic variety equipped with an action of the infinite general linear group under which the coordinate ring forms a polynomial representation. Such varieties have been used to study asymptotic properties of invariants like strength and tensor rank and played a key role in two recent proofs of Stillman’s conjecture. We initiate a systematic study of $\textbf {GL}$-varieties and establish a number of foundational results about them. For example, we prove a version of Chevalley’s theorem on constructible sets in this setting.
Integrated infrared thermography and accelerometer-based behavior logger as a hoof lesion identification tool in dairy cows with various foot diseases under subtropical climates
Authors: Chiu Yun-Jung , Hsu Jih-Tay 
Published: August 2022

AbstractInfrared thermography (IRT) can measure a temperature change on the surface of objects, and is widely used as an inflammation or fever detection tool. The objective of this longitudinal study was to investigate the feasibility of detecting hoof lesion cattle using IRT under subtropical climate conditions. The experiment was conducted in two free-stall commercial dairy farms and 502 dairy cows participated between August 2020 and March 2022. Before hoof trimming, the portable IRT was used to measure the maximum temperature of each hoof from three shooting directions, including anterior (hoof coronary band), lateral (hoof lateral coronary band), and posterior (skin between heel and bulbs). In order to evaluate the effect of hoof lesions on the behavior of dairy cows, we also collected behavior data by automated accelerometers. The results indicated that the temperature of hooves with lesions was significantly higher than that of sound hooves in hot environments regardless of the shooting directions (P &lt; 0.0001). In all of three shooting directions, the maximum temperature of feet with severe lesion was significantly higher than those of feet with mild lesion and sound feet (P &lt; 0.05). Cows with lesion feet had lower daily activity and feeding time than sound cows before clinical diagnosis (P &lt; 0.05). Furthermore, we used thresholds of both anterior hoof temperature at 32.05 °C and average daily activity at 410.5 (arbitrary unit/d) as a lame cow detecting tool. The agreement of this integrated tool reached 75% with clinical diagnosis, indicating that this integrated approach may be feasible for practice in dairy farm. In conclusion, IRT has the potential to be used as a hoof lesion detecting tool under subtropical climate conditions when using sound hoof temperature as reference points, and detection precision can be improved when IRT integrated with automated accelerometers as a lame cow detecting tool.

AbstractDuring the COVID-19 pandemic, children were out of school due to Stay-at-Home Orders. The objective of this study was to investigate how the COVID-19 pandemic may have impacted the incidence of burn injuries in children. Eight Level I Pediatric Trauma Centers participated in a retrospective study evaluating children &lt;18 years old with traumatic injuries defined by the National Trauma Data Bank. Patients with burn injuries were identified by ICD-10 codes. Historical controls from March to September 2019 (“Control” cohort) were compared to patients injured after the start of the COVID-19 pandemic from March to September 2020 (“COVID” cohort). A total of 12,549 pediatric trauma patients were included, of which 916 patients had burn injuries. Burn injuries increased after the start of the pandemic (COVID 522/6711 [7.8%] vs Control 394/5838 [6.7%], P = .03). There were no significant differences in age, race, insurance status, burn severity, injury severity score, intent or location of injury, and occurrence on a weekday or weekend between cohorts. There was an increase in flame burns (COVID 140/522 [26.8%] vs Control 75/394 [19.0%], P = .01) and a decrease in contact burns (COVID 118/522 [22.6%] vs Control 112/394 [28.4%], P = .05). More patients were transferred from an outside institution (COVID 315/522 patients [60.3%] vs Control 208/394 patients [52.8%], P = .02), and intensive care unit length of stay increased (COVID median 3.5 days [interquartile range 2.0–11.0] vs Control median 3.0 days [interquartile range 1.0–4.0], P = .05). Pediatric burn injuries increased after the start of the COVID-19 pandemic despite Stay-at-Home Orders intended to optimize health and increase public safety.
Improving plant heat tolerance through modification of Rubisco activase in C3 plants to secure crop yield and food security in a future warming world
Authors: Qu Yuchen , Mueller-Cajar Oliver , Yamori Wataru 
Published: August 2022

Abstract
The world’s population may reach 10 billion by 2050, but 10% still suffer from food shortages. At the same time, global warming threatens food security by decreasing crop yields, so it is necessary to develop crops with enhanced resistance to high temperatures in order to secure the food supply. In this review, the role of Rubisco activase as an important factor in plant heat tolerance is summarized, based on the conclusions of recent findings. Rubisco activase is a molecular chaperone determining the activation of Rubisco, whose heat sensitivity causes reductions of photosynthesis at high temperatures. Thus, the thermostability of Rubisco activase is considered to be critical for improving plant heat tolerance. It has been shown that the introduction of thermostable Rubisco activase through gene editing into Arabidopsis thaliana and from heat-adapted wild Oryza species or C4Zea mays into Oryza sativa improves Rubisco activation, photosynthesis, and plant growth at high temperatures. We propose that developing a universal thermostable Rubisco activase could be a promising direction for further studies.
On Transcultural Presence and Reparative Reading Practice: Rethinking Belonging and Transcultural Transformation in Julia Alvarez’s How the García Girls Lost Their Accents
Authors: Roupakia Efthymia Lydia 
Published: August 2022

Abstract
I offer a reading of the opening chapter of Julia Alvarez’s novel How the García Girls Lost Their Accents (1991) through Bill Ashcroft’s approach to “transcultural presence.” I argue that Alvarez’s opening chapter casts the experience of transcultural presence as a complex and conflicted emotional space that challenges the reader’s appreciation of belonging beyond received interpretative frameworks. I further draw on Sten Pulz Moslund’s theoretical engagement with the “presencing” of place through a “topopoetic mode of reading.” I propose that the presencing of place in the opening chapter of Alvarez’s novel encourages a located, embodied way of reading transformative moments of transcultural presence. Finally, I suggest that Alvarez’s ethics of postcolonial, transcultural writing encourages what Eve Kosofsky Sedgwick has referred to as “reparative reading.” “Reparative reading” is illustrated in terms of the literary text’s opening up toward the “volume” of transcultural complexity, an opening up that calls for self-reflexive interpretative caution and care for locative particularity when engaging with transcultural literature.
The X-ray emission of Be+stripped star binaries★
Authors: Nazé Yaël , Rauw Gregor , Smith Myron A , Motch Christian 
Published: August 2022

ABSTRACT
Using observations from Chandra, Swift, and XMM-Newton, we investigate the high-energy properties of all known (18) Be+sdO systems as well as seven additional Be binaries suspected to harbour stripped stars. The observed X-ray properties are found to be similar to those observed for other Be samples. The vast majority of these systems (15 out of 25) display very faint (and soft) X-ray emission, and six others are certainly not bright X-ray sources. Only two systems display γ Cas characteristics (i.e. bright and hard X-rays), and one of them is a new detection: HD 37202 (ζ Tau). It presents an extremely hard spectrum due to a combination of high temperature and high absorption (possibly due to its high inclination). In parallel, it may be noted that the previously reported cyclic behaviour of this Be star has disappeared in recent years. Instead, shorter cycles and symmetric line profiles are observed for the Hα line. It had been recently suggested that the peculiar X-ray emissions observed in γ Cas stars could arise from a collision between the disc of a Be star and the wind of its hot, stripped-star companion. The small fraction of γ Cas analogues in this sample, as well as the properties of the known companions of the γ Cas cases (low mass or not extremely hot, contrary to predictions), combined to the actual stripped-star and colliding-wind empirical knowledge, make the disc-wind collision an unlikely scenario to explain the γ Cas phenomenon.
