Ecology as Method
Authors: Visser Robin 
Published: June 2020

Abstract
In “China as Method,” Mizoguchi Yūzō argues that “a world that takes China as method would be a world in which China is a constitutive element.” Similarly, a world that takes ecology as method is a world in which humans are a constitutive element, one of “the ten thousand things” (wanwu 萬物). In this essay, the author examines distinct ways in which fictional writers imagine relational dynamics between humans, nonhuman animals, regional ecosystems, and the cosmos to theorize ecology as method. Ecology as method works to radically decenter anthropocentric understandings of the cosmos, historicizes regional ecologies in order to illuminate global dynamics, and acknowledges deterritorialization. While mourning loss, it resists sentimentalizing cultural narratives that rationalize the genocide of species as inevitable. This article focuses on three contemporary eco-writers of Inner Mongolia. Mandumai 滿都麥, one of the People's Republic of China's earliest post-Mao eco-writers, romanticizes indigeneity in his Mongolian-language stories (read in this article in Mandarin translation). Mongolian-Han Sinophone writer Guo Xuebo 郭雪波 juxtaposes “grassland logic” against “agrarian logic” in his desert fiction series, illustrating how agrilogistics dominates the ecological imagination of the ethnically diverse desert-dwellers. Finally, the article analyzes the best-selling Wolf Totem by Beijing-based sent-down youth Jiang Rong 姜戎. Despite attributing desertification to Han ignorance, the novel simultaneously maps the steppes via ecological understandings from Hanspace ontology.
Pandemic as Method
Authors: Kong Belinda 
Published: June 2020

AbstractThis essay deploys the concept of pandemic as a set of discursive relations rather than a neutral description of a natural phenomenon, arguing that pandemic discourse is a product of layered histories of power that in turn reproduces myriad forms of imperial and racial power in the new millennium. The essay aims to denaturalize the idea of infectious disease by reframing it as an assemblage of multiple histories of American geopower and biopower from the Cold War to the War on Terror. In particular, Asia and Asian bodies have been targeted by US discourses of infection and biosecurity as frontiers of bioterrorism and the diseased other. A contemporary example of this bio-orientalism can be seen around the 2003 SARS epidemic, in which global discourses projected the source of contagion onto Asia and Asians. Pandemic as method can thus serve as a theoretical pathway for examining cultural concatenations of orientalism and biopower.
Script as Method
Authors: Pang Laikwan , Ko Chun-Kit 
Published: June 2020

Abstract
This essay argues that the two main types of contemporary Chinese scripts, complicated characters (fantizi 繁體字) and simplified characters (jiantizi 簡體字), are sites of heavy cultural and political contestation. The two script systems witness the internal bifurcation of the Chinese written language, which should not be considered as unified vis-à-vis the diversification of the verbal languages. Supported with many concrete examples, the essay demonstrates the different kinds of political struggles involved in the publication of the same materials in the two different scripts. These cases also illustrate the heavy censorship involved in contemporary PRC literature, and the authors are particularly interested in demonstrating the meanings of the option of fantizi publication toward many PRC writers. The two scripts could not be understood as simple variations of the same set of language, but the shifts between them involve actual translations, which in turn would help us gain new insights on the idea of world literature.

Aims The aim of this study was to report the medium-term outcomes of impaction bone allograft and fibular grafting for osteonecrosis of the femoral head (ONFH) and to define the optimal indications. Methods A total of 67 patients (77 hips) with ONFH were enrolled in a single centre retrospective review. Success of the procedure was assessed using the Harris Hip Score (HHS) and rate of revision to total hip arthroplasty (THA). Risk factors were studied, including age, aetiology, duration of hip pain, as well as two classification systems (Association Research Circulation Osseous (ARCO) and Japanese Investigation Committee (JIC) systems). Results After a mean follow-up period of 8.61 years (SD 1.45), 81.3% (52/64) of enrolled cases had a good or excellent HHS at latest follow-up (declining to 76.0% (38/50) for those with more than eight years of follow-up). Overall survival was 92.1% at eight years’ follow-up (95% CI 83.2% to 96.4%). A total of 12 hips (19.0%) failed (reoperation or HHS < 70 points) at final follow-up. Rate of success was adversely affected by increasing age, duration of pain, and more severe disease as measured using the ARCO and JIC classifications, but not by aetiology of the ONFH. Conclusion We report favourable medium-term results of this procedure. Best outcomes can be expected in patients matching the following indications: younger than 40 years; less 12-month hip pain before surgery; femoral head collapse being less than 2 mm; and integrated lateral wall of femoral head.

A survey of Hip Society surgeons concerning the direct anterior approach total hip arthroplasty
Authors: Woolson Steven T. 
Published: June 2020

Aims To establish whether there was a consensus among the members of the Hip Society (HS) on the role of direct anterior approach (DAA) contemporary primary total hip arthroplasty (THA). Methods An online survey was sent to all 112 active and senior members of the HS, to which 71 members responded. The survey was constructed to determine whether they believed that evidence-based medicine proves, in modern clinical practice, that the DAA has significant benefits compared to risks when contrasted with other approaches. In addition, they were asked if they currently used the DAA. Results While only 16.9% (12/71) of respondents had been trained in a generic anterior approach during residency, 49.3% (35/71) had used the DAA in their clinical practice in the past or were using it at the present time. Unexpectedly, 42.9% (15/35) of respondents who had used the DAA in the past had abandoned it by the time of this survey. Only 22.5% (16/71) of all respondents believed that evidence-based medicine proves that the DAA has significant benefits compared to risks in contrast to other approaches. Conclusion A comprehensive literature review found only three prospective randomized clinical trials (RCT) comparing the DAA with another approach with greater than one-year follow-up. Two showed minor benefits within the early postoperative period only, and one of those showed poorer mid-term results. Most of the published comparison studies with short follow-up show longer surgical times and greater blood loss for the DAA, and many three-month comparison studies show higher complication rates for the DAA using a proprietary traction table. The complications included problems with wound healing, lateral femoral cutaneous nerve injury, femoral component loosening, and femoral fractures. Because of the lack of evidence from RCTs showing superiority of the DAA over other approaches and reports of higher complications, the opinion of a large majority (77.5%; 55/71) of HS surgeons was that the DAA lacks sufficient evidence to warrant its use.

AimsThe primary aim of this paper was to outline the processes involved in building the Partners Arthroplasty Registry (PAR), established in April 2016 to capture baseline and outcome data for patients undergoing arthroplasty in a regional healthcare system. A secondary aim was to determine the quality of PAR’s data. A tertiary aim was to report preliminary findings from the registry and contributions to quality improvement initiatives and research up to March 2019.MethodsStructured Query Language was used to obtain data relating to patients who underwent total hip or knee arthroplasty (THA and TKA) from the hospital network’s electronic medical record (EMR) system to be included in the PAR. Data were stored in a secure database and visualized in dashboards. Quality assurance of PAR data was performed by review of the medical records. Capture rate was determined by comparing two months of PAR data with operating room schedules. Linear and binary logistic regression models were constructed to determine if length of stay (LOS), discharge to a care home, and readmission rates improved between 2016 and 2019.ResultsThe PAR captured 16,163 THAs and TKAs between April 2016 and March 2019, performed in seven hospitals by 110 surgeons. Manual comparison to operating schedules showed a 100% capture rate. Review of the records was performed for 2,603 random operations; 2,298 (88.3%) had complete and accurate data. The PAR provided the data for three abstracts presented at international conferences and has led to preoperative mental health treatment as a quality improvement initiative in the participating institutions. For primary THA and TKA surgeries, the LOS decreased significantly (p < 0.001) and the rate of home discharge increased significantly (p < 0.001) between 2016 and 2019. Readmission rates did not correlated with the date of surgery (p = 0.953).ConclusionThe PAR has high rates of coverage (the number of patients treated within the Partners healthcare network) and data completion and can be used for both research purposes and quality improvement. The same method of creating a registry that was used in the PAR can be applied to hospitals using similar EMR systems. Cite this article: Bone Joint J 2020;102-B(7 Supple B):90–98.

Aims Cementless unicompartmental knee arthroplasty (UKA) has advantages over cemented UKA, including improved fixation, but has a higher risk of tibial plateau fracture, particularly in Japanese patients. The aim of this multicentre study was to determine when cementless tibial components could safely be used in Japanese patients based on the size and shape of the tibia. Methods The study involved 212 cementless Oxford UKAs which were undertaken in 174 patients in six hospitals. The medial eminence line (MEL), which is a line parallel to the tibial axis passing through the tip of medial intercondylar eminence, was drawn on preoperative radiographs. Knees were classified as having a very overhanging medial tibial condyle if this line passed medial to the medial tibial cortex. They were also classified as very small if a size A/AA tibial component was used. Results The overall rate of fracture was 8% (17 out of 212 knees). The rate was higher in knees with very overhanging condyles (Odds ratio (OR) 13; p < 0.001) and with very small components (OR 7; p < 0.001). The OR was 21 (p < 0.001) in those with both very overhanging condyles and very small components. In all, 69% of knees (147) had neither very overhanging nor very small components, and the fracture rate in these patients was 1.4% (2 out of 147 knees). Males had a significantly reduced risk of fracture (OR 0.13; p = 0.002), probably because no males required very small components and females were more likely to have very overhanging condyles (OR 3; p = 0.013). 31% of knees (66) were in males and in these the rate of fracture was 1.5% (1 out of 66 knees). Conclusion The rate of tibial plateau fracture in Japanese patients undergoing cementless UKA is high. We recommend that cemented tibial fixation should be used in Japanese patients who require very small components or have very overhanging condyles, as identified from preoperative radiographs. In the remaining 69% of knees cementless fixation can be used. This approach should result in a low rate of fracture. Cite this article: Bone Joint J 2020;102-B(7):861–867.

Published: June 2020

Aims The COVID-19 pandemic presents a significant threat to patients with neck of femur fractures. The 30-day mortality for these patients has gradually been reducing in the UK due to a multitude of inputs aimed at improving their outcomes. We provided an early assessment of 30-day mortality in neck of femur fracture patients who contracted COVID-19. Methods We identified 18 patients who were admitted from three acute hospital sites who underwent an operation for a neck of femur fracture and were diagnosed with COVID-19 between 25 March and 25 April 2020. We collected information on their age, American Association of Anesthesiologists (ASA) grade, diagnosis, surgical procedure, complications, and 30-day mortality. Results Our study identified 18 patients who were all diagnosed with a positive swab result during the postoperative period. Female patients made up two-thirds of the patient cohort and the mean age of patients was 82 years (55 to 101). In all, ten patients sustained intracapsular fractures with eight sustaining extracapsular fractures. The 30-day mortality in this group of patients was 22.2% as compared to 4% 30-day mortality in those without COVID-19. Conclusion Our results show a 30-day mortality of 22.2%, which is higher than the national average provided by the 2019 National Hip Fracture Database report. However, while 30-day mortality has increased in those patients with COVID-19, this should not impact upon the provision of hip fracture surgery as it provides significant benefits to the patient such as pain relief and early mobilization. However, the information presented in this study should form an important part of the informed consent process for surgery. A multidisciplinary approach is crucial in ensuring optimal care for this complex patient group. Cite this article: Bone Joint Open 2020;1-7:326–329.

Published: June 2020

In this work, one kind of type II ZnSe/CdS/ZnS core/shell/shell nanocrystals (NCs) is synthesized, and their linear and nonlinear photophysical properties are investigated. Through measurements of the temperature-dependent photoluminescence spectra of NCs, their excitonic properties, including the coefficient of the bandgap change, coupling strength of the exciton acoustic phonons, exciton longitudinal optical (LO) phonons, and LO–phonon energy are revealed. Femtosecond transient absorption spectroscopy was employed to obtain insight into ultrafast processes occurring at the interface of ZnSe and CdS, such as those involving the injection of photo-induced electrons into the CdS shell, interfacial state bleaching, and charge separation time. At the end, their multiphoton absorption spectra were determined by using the z-scan technique, which yielded a maximum two-photon absorption cross section of 3717 GM at 820 nm and three-photon absorption cross section up to

Published: June 2020

Contexto: El agua es esencial para la vida y la conservación de su calidad es vital. La cantidad de agua dulce existente en la Tierra es limitada, y su calidad está sometida a una presión constante. Esta problemática hace necesario generar herramientas que permitan medir los impactos potenciales que causan las actividades humanas sobre el recurso hídrico. Por ello, esta investigación determina la huella hídrica en la zona costera de San Blas, México.
Método: Este trabajo estima la huella de agua en la zona costera del municipio de San Blas, Nayarit (México), a partir del método de escasez de agua, que tiene lugar cuando la demanda supera el suministro de agua dulce en un área determinada. Este método considera el índice de estrés hídrico en su cálculo.
Resultados: La huella de agua para cuantificar el volumen total del líquido utilizado por los habitantes resulta inferior al promedio nacional. De esta manera, la zona de estudio no presenta estrés hídrico, ya que la extracción de agua no ha superado su disponibilidad.
Conclusiones: La huella hídrica por el método de escasez puede considerarse como un indicador de la proporción de extracciones anuales y disponibilidad de agua; permite realizar comparaciones de la presión a la que está sometido el recurso hídrico entre zonas, regiones y países. Además, puede contribuir a la planificación de la distribución y gestión del agua en uso agrícola y urbano, en regiones como este estudio, donde el área de uso agrícola supera el 35 %. La estimación de la huella hídrica presentada en este trabajo considera la relación entre la extracción de agua dulce para uso humano y su disponibilidad total de agua en una región dada (WSI), el volumen distribuido y el porcentaje de cobertura de agua potable del área en estudio.

Based on BPS data, the transportation industry sector contributed to about 8.01% of Indonesia's economic growth. The rapid growth of the transportation industry is also followed by the development of the automotive industry in Indonesia. The Exclusive Lisencee Agent of the Astra International group won a market share of 57% in April 2017. PT. Astra Daihatsu Motor, which is one of its subsidiaries, has a very rapid sales increase of 15% every year until Daihatsu's market share rises to 17.3%. Data from the Gabungan Industri Kendaraan Bermotor Indonesia (Gaikindo) shows an upward trend in car sales a month before Idul Fitri. This study carried out Daihatsu's direct and indirect market share forecasting using ARIMAX with a variety of calendar effects consisting of trends, monthly seasonal effects and Idul Fitri effects. The results indicated that indirect forecasting through forecasting the car sales for each brand and total market using ARIMAX outperforms the others and is able to capture the pattern of the testing data. The resulting SMAPE value of ARIMAX is smaller than direct forecasting and indirect forecasting using ARIMA.
High-efficiency, large-area lattice light-sheet generation by dielectric metasurfaces
Authors: Shi Fenghua , Wen Jing , Lei Dangyuan 
Published: June 2020

Abstract
Lattice light-sheet microscopy (LLSM) was developed for long-term live-cell imaging with ultra-fine three-dimensional (3D) spatial resolution, high temporal resolution, and low photo-toxicity by illuminating the sample with a thin lattice-like light-sheet. Currently available schemes for generating thin lattice light-sheets often require complex optical designs. Meanwhile, limited by the bulky objective lens and optical components, the light throughput of existing LLSM systems is rather low. To circumvent the above problems, we utilize a dielectric metasurface of a single footprint to replace the conventional illumination modules used in the conventional LLSM and generate a lattice light-sheet with a ~3-fold broader illumination area and a significantly leveraged illumination efficiency, which consequently leads to a larger field of view with a higher temporal resolution at no extra cost of the spatial resolution. We demonstrate that the metasurface can manipulate spatial frequencies of an input laser beam in orthogonal directions independently to break the trade-off between the field of view and illumination efficiency of the lattice light-sheet. Compared to the conventional LLSM, our metasurface module serving as an ultra-compact illumination component for LLSM at an ease will potentially enable a finer spatial resolution with a larger numerical-aperture detection objective lens.

AbstractEffective dynamic modulation of visible light properties has been significantly desired for advanced imaging and sensing technologies. In particular, phase-change materials have attracted much attention as active material platforms owing to their broadband tunability of optical dielectric functions induced by the temperature-dependent phase-changes. However, their uses for visible light modulators are still limited to meet multi-objective high performance owing to the low material quality factor and active tunability in the visible regime. Here, a design strategy of phase-change metafilm absorber is demonstrated by making the use of the material drawbacks and extending design degree of freedom. By engineering tunability of effective anisotropic permittivity tensor of VO2-Ag metafilm around near-unity absorption conditions, strong dynamic modulation of reflection wave is achieved with near-unity modulation depth at desired wavelength regions without sacrificing bandwidth and efficiency. By leveraging effective medium theory of metamaterial and coupled mode theory, the intuitive design rules and theoretical backgrounds are suggested. It is also noteworthy that the dynamic optical applications of intensity modulation, coloring, and polarization rotation are enabled in a single device. By virtue of ultrathin flat configuration of a metafilm absorber, design extensibility of reflection spectrum is also verified. It is envisioned that our simple and powerful strategy would play a robust role in development of miniaturized light modulating pixels and a variety of photonic and optoelectronic applications.
