Ideology of the Image: Wu Guanzhong's Abstract Expression, 1979–1983
Authors: Lee Jennifer Dorothy 
Published: May 2024

Abstract
This article examines the discourse of abstraction among Beijing intellectuals in response to the artist Wu Guanzhong's 吴冠中 (1919–2010) published essays on formal and abstract beauty from 1979 and 1980. By introducing Wu through a new critical lens that emphasizes his writings and institutional critique, the author addresses how abstraction was repurposed for early post-Mao China. Where institutional elites in Beijing regarded painterly abstraction with unease, owing to its continued associations with the bourgeois-capitalist art worlds of Paris and New York, this article shows how Wu performed an aesthetic intervention through writing, utilizing scientism and Maoist logic to filter abstraction through the still-hegemonic language of radical materialism, which allowed abstraction to take hold as a renewed term of engagement in the early post-Mao art world by 1983. This article is a shortened version of a chapter in the author's recently published book.
Pema Tseden's Balloon: Reincarnation of a Semi-transparent Envelope
Authors: Yang Yuqing 
Published: May 2024

Abstract
Buddhism provides the vocabulary for film auteur Pema Tseden to express a psychological dimension in his Amdo-Tibetan stories. Drawing on the Tibetan Buddhist concept of bardo, the transitional space between sleep and waking, or death and rebirth, his works encapsulate surrealist flow of consciousness of the characters as they are torn between religious principles, modern imperatives, and conscience. Specifically, Balloon exposes an Amdo woman's choice between having an abortion in compliance with China's 1990s birth control policy or enabling the prophesized rebirth of a family forebear. The film extends Pema Tseden's earlier experiment in Jinpa, which enacts an intrapsychic dialogue in a dream, by using a religiously inflected visualization of the state of mind in the threshold between death and the next life. Balloon's passionate reenactment of a luminous afterlife landscape and its reflexive and even questioning attitudes toward the concept of reincarnation create an intriguing tension. Its central imagery, the inflated condom balloon, is a “semi-transparent envelope,” to borrow British novelist Virginia Woolf's phrase, which suggests the inscrutability of the characters’ internal experiences. The balloon is also a “semi-transparent filter” of the director's ambiguous affects, encapsulating cultural intimacy and cultural contemplation within a non-dual framework.
Eccentric Exercise–Induced Muscle Damage Reduces Gross Efficiency
Authors: HORNER DANIEL , JEFFRIES OWEN , BROWNSTEIN CALLUM G. 
Published: May 2024

ABSTRACT

Introduction
The effect of eccentric exercise–induced muscle damage (EIMD) on cycling efficiency is unknown. The aim of the present study was to assess the effect of EIMD on gross and delta efficiency and the cardiopulmonary responses to cycle ergometry.

Methods
Twenty-one recreational athletes performed cycling at 70%, 90%, and 110% of the gas exchange threshold (GET) under control conditions (Control) and 24 h following an eccentric damaging protocol (Damage). Knee extensor isometric maximal voluntary contraction, potentiated twitch (Q
tw,pot), and voluntary activation were assessed before Control and Damage. Gross and delta efficiency were assessed using indirect calorimetry, and cardiopulmonary responses were measured at each power output. Electromyography root-mean-square (EMGRMS) during cycling was also determined.

Results
Maximal voluntary contraction was 25% ± 18% lower for Damage than Control (P < 0.001). Gross efficiency was lower for Damage than Control (P < 0.001) by 0.55% ± 0.79%, 0.59% ± 0.73%, and 0.60% ± 0.87% for 70%, 90%, and 110% GET, respectively. Delta efficiency was unchanged between conditions (P = 0.513). Concurrently, cycling EMGRMS was higher for Damage than Control (P = 0.004). An intensity-dependent increase in breath frequency and V̇E/V̇CO2 was found, which were higher for Damage only at 110% GET (P ≤ 0.019).

Conclusions
Thus, gross efficiency is reduced following EIMD. The concurrently higher EMGRMS suggests that increases in muscle activation in the presence of EIMD might have contributed to reduced gross efficiency. The lack of change in delta efficiency might relate to its poor reliability hindering the ability to detect change. The findings also show that EIMD-associated hyperventilation is dependent on exercise intensity, which might relate to increases in central command with EIMD.

Introduction: Infections caused by Klebsiella pneumoniae carbapenemase (KPC) pose a significant clinical challenge due to increasing antibiotic resistance. This study analyzes the effectiveness of ceftazidime/avibactam treatment for KPC infections, focusing on 30-day mortality and comparing results with control groups treated with different antibiotics.
Material and methods: We conducted a retrospective analysis of six cohort studies, comparing thirty-day mortality in patients treated with ceftazidime/avibactam with control groups using other antibiotics. The studies included patients infected with KPC, and the analysis focused on therapeutic effectiveness.
Aim of the study: The aim of the study is to compare the results in terms of 30-day mortality in groups treated with ceftazidime/avibactam compared to control groups using different antibiotics.

Conclusions: Data analysis from various studies revealed varied 30-day mortality outcomes in groups treated with ceftazidime/avibactam compared to control groups using different antibiotics. Ceftazidime/avibactam proved to be more effective in all studies, reducing mortality rates compared to other treatment regimens. We emphasize that emerging antibiotic resistance, especially in the case of KPC, requires a comprehensive therapeutic approach. Despite promising ceftazidime/avibactam results, factors such as overall patient health and treatment delays may influence final therapy outcomes. We also highlight controversies regarding combination therapy vs. monotherapy, necessitating further research. Our work underscores the importance of monitoring the effectiveness of KPC infection treatment and exploring new therapeutic strategies. Further clinical studies are essential to develop a fuller understanding and optimal therapeutic protocols in the face of the growing antibiotic resistance problem.

Background. This publication initiates the project "Neuro-endocrine regulation of the clearance of nitrogenous metabolites". The first stage of project implementation is the clarification of peculiarities of metabolic and neuro-endocrine accompaniments of urate-losing and urate-retaining kidneys. Materials and Methods. The object of observations were patients with chronic pyelonephritis in the phase of remission (34 males aged 23-70 years and 10 females aged 33-76 years). Testing was performed twice - on admission and after 7-10 days of standard balneotherapy on Truskavets Spa. The battery of tests was created in line with concepts functional-metabolic continuum and NEI network. The content of nitrogenous metabolites and electrolytes was determined in daily urine and blood serum. In addition, indicators of the lipoprotein spectrum and lipids peroxidation, as well as the level of the main adaptation hormones, were determined in the blood. The state of the autonomic nervous system was assessed by the HRV method. Results. In 63.6% of cases, the renal clearance of uric acid was within the classical norm (±2σ), in 12.5% it was moderately reduced, but in the remaining cases it was increased, including drastically in 3 cases. The method of discriminant analysis revealed 20 parameters, according to the totality of which all 4 clusters of uric acid clearance clearly differ from each other (classification accuracy 100%). Conclusion. Constitutionally distinct types of uric acid metabolism (euricosis, urate-losing and urate-retaining kidneys) are characterized by specific constellations of metabolic and autonomic-endocrine parameters.
Comparing congratulatory speech in Javanese and Sundanese: influence of culture on strategies
Authors: Nofendralova Shena Fiosa , Sartini Ni Wayan 
Published: May 2024

While several expressive speech acts like requesting, apologizing, and inviting had been widely studied, the speech act of congratulating has been given little attention. This study compared how Javanese and Sundanese speakers congratulate each other, which has not been studied much before. This research also looked at how age, social power, and social distance affect the way people congratulate each other. The contribution of this paper lies in providing a nuanced understanding of how cultural and social values in Javanese and Sundanese societies shape congratulatory speech acts. The study involved 60 participants who completed a written Discourse Completion Task (DCT). A mixed-method approach combining quantitative and qualitative methods was used for analysis. The data was coded and categorized using Elwood's (2004) framework. The study identified new strategies, such as mentioning occasion and divine remarks, that were significant in relation to the dataset. Participants responded to five real-life situations by providing congratulatory expressions in their local language on a Google Form. The most frequently utilized strategy is the expression of surprise which is followed by IFID in the second position. The presence of divine remarks in the act of congratulating in this study is attributed with the highly influence of Islamic culture in Indonesia. In terms of social position, social distance, and age, both groups demonstrate a preference for employing High variety (H) when interacting with individuals with higher position or older individuals.
Experimental demonstration of positioning the cooperation terminal for underwater wireless optical communication based on visual navigation

Published: May 2024

Underwater wireless optical communication (UWOC) is a useful way to transmit a large
volume of data in ocean engineering. In application, one of the UWOC
terminals is usually carried on an underwater robot to actively adjust
its orientation and position to establish an optical link, which
requires the mobile terminal to locate the cooperation partner. At a
short communication distance, visual navigation is a preferred method
to measure the position. In this method, a camera is installed on the
mobile terminal while several light-emitting diodes (LEDs) are in the
cooperation one. In the image of the camera, by capturing the pattern
formed of LEDs light spots, the relative position and orientation
between terminals could be calculated. However, in a UWOC system,
visual navigation is interfered with by the UWOC transmitter since it
forms an additional light spot in the camera’s image. To solve this
issue, we present a UWOC-compatible visual navigation method, in which
the UWOC light spot is distinguished with the hue, saturation, and
value (HSV) color model. Then, we experimentally demonstrate the
effectiveness of the method in a pool, applying signals with different
bitrates and power on the transmitter. The results show that, while
the distance between terminals is within 350 cm and the yaw
angle is within 5°, the measured errors are within 1.77 cm and
0.92°, respectively, which is accurate enough for most UWOC
applications. The method presented in this paper is simple, pragmatic,
and useful for establishing a UWOC link.
Tunable terahertz absorber based on quasi-BIC supported by a graphene metasurface

Published: May 2024

In this paper, a tunable terahertz (THz) absorber operating at a quasi-bound state in the continuum (quasi-BIC) mode supported by a graphene metasurface is proposed. There are two graphene strips and a fully covered graphene layer in one unit cell. By breaking the symmetrical arrangement of graphene stripes, the symmetry-protected BIC transforms into a quasi-BIC mode. The reflective configuration results in high-Q absorption of the metadevice at the quasi-BIC mode with the equivalent impedance matching the impedance in free space. The change in the Fermi level of graphene can cause a frequency shift in the position of the absorption peak at the quasi-BIC mode. Benefiting from the high Q-value and narrow linewidth of the quasi-BIC, the frequency shift of the absorption peak can easily exceed its linewidth. At this time, the designed THz absorber can be used as a switch, and the “on” and “off” states are achieved by tuning the Fermi level of graphene. Under normal incidence, the modulation depth of the absorption type THz switch can reach up to 99% with the insertion loss only 0.062 dB. Within the range of incident angle inclination approaching 10°, the absorption type THz switch can still achieve more than 90% modulation depth and insertion loss below 0.1 dB. Due to the characteristics of large modulation depth, low insertion loss, and wide angle incidence, the designed tunable THz absorber has great application prospects in fields such as THz communication and THz wavelength division multiplexing.

Published: May 2024

An O-band monolithically integrated four-channel laser array based on
high-order surface gratings is demonstrated. The fabricated laser
array exhibits a wide bandwidth of up to 60 nm, with threshold
currents ranging from 17 to 25 mA and slope efficiencies
between 0.22 and 0.29 W/A. At an injection current of
200 mA, all side-mode suppression ratios (SMSRs) are above
40 dB, and the output power exceeds 36 mW. The
high-order surface gratings are fabricated by standard lithography,
which avoids high-precision lithography and a complex regrowth
technique. A potentially cost-effective light source for coarse
wavelength division multiplexing (CWDM) systems is provided.

Published: May 2024

A photonic crystal fiber (PCF) sensor based on surface plasmon resonance (SPR) with a graphene coating on the cladding is designed for refractive index (RI) detection in the range of 0.3–0.5 THz, especially for liquid bioanalytical sensing. The adjustability of the graphene chemical potential (E
f
) enables dynamic tuning of the loss spectra over a wide frequency range with a tuning sensitivity of 570 GHz/eV at the SPR frequency. According to the analysis by the finite element method (FEM), the highest wavelength sensitivity and maximum amplitude sensitivity of 4254.11 µm/RIU and 25.62RIU−1 (n
a
=1.34) are achieved in the RI range of 1.15–1.35, respectively, together with a resolution of 5.93×10−5RIU. The graphene PCF-SPR sensor boasting high-sensitivity detection in a wide RI range has broad application prospects in multiple fields.
Spectropolarimetric properties of vortex retarders
Authors: James Ella E. , Anderson Isaac M. , Gregory Don A. 
Published: May 2024

Vortex retarders are optical retarders with a uniform retardance, but with a fast axis that varies azimuthally over the area of the optic. This affects the radial and azimuthal polarization components of the incoming beam. The vortex retarders discussed here generate TEM10 and TEM20 Laguerre-Gaussian beams. While several varieties of these vortex retarders exist, designed to function at specific wavelengths, and a few studies have reported their use at those wavelengths, almost no data exists detailing their polarimetric properties outside those wavelengths. Using a Mueller matrix spectropolarimeter with dual-rotating retarders, the polarization properties of four zero-order half-wave vortex retarders have been measured across a broad wavelength range of 300–1100 nm. This data contributes to a more complete description of the spectral properties of these popular retarders.

Published: May 2024

IntroductionMaternal morbidity and mortality has remained a major public health concern worldwide. Basic emergency obstetric care is the primary intervention to prevent obstetric complications and maternal death. Episiotomy is one of the basic obstetrical procedures used to facilitate vaginal delivery, shorten the second stage of labor and prevent complications. However, there is a paucity of evidence on the prevalence and factors associated with episiotomy among women who gave birth in eastern Ethiopia.ObjectiveThis study aimed to determine the prevalence of episiotomy and its associated factors among women who gave birth at public health facilities in Jigjiga town, eastern Ethiopia.MethodsA facility-based cross-sectional study was conducted among women who gave birth vaginally from May 1 to June 30, 2022. A total of 422 study participants were recruited using systematic random sampling. Data were collected using structured questionnaires through a face-to-face interview supported with standard observational checklist and reviewing medical records. A logistic regression analysis was carried out to examine the association between explanatory variables and episiotomy. An adjusted odds ratio (AOR) at a 95% confidence interval (CI) at a P-value <0.05 was used to declare significant association.ResultsThe prevalence of episiotomy among women was 52.6% (95% CI: 47.8%, 57.0%). Obstetric complications during current pregnancy (AOR:3.92, 95% CI: 1.59, 9.68), birth weight ≥4000 gm (AOR: 4.30, 95% CI: 1.53, 12.04), induction of labor (AOR: 3.10, 95% CI: 1.62, 5.93), meconium-stained amniotic fluid (AOR:2.10, 95% CI: 1.14, 3.88), duration of the second stage of labor ≥90 minutes (AOR:3.09, 95% CI: 1.53, 6.23), instrumental delivery (AOR: 2.69, 95%, CI: 1.39, 5.19), and female genital mutilation (AOR: 2.91, 95% CI: 1.83, 4.64) were factors significantly associated with episiotomy.ConclusionSlightly more than half of the women who gave birth at public health facilities in the study area underwent episiotomies. In addition to the common obstetric factors, having a female genital mutilation scar increased the risk of women’s experiencing episiotomies. Therefore, intervention should be tailored to address the identified obstetric risk factors and avoid female genital mutilation in the community to reduce women’s experiences of episiotomies in the future.

Background
Syndromic management is widely used to treat symptomatic sexually transmitted infections in settings without aetiologic diagnostics. However, underlying aetiologies and consequent treatment suitability are uncertain without regular assessment. This systematic review estimated the distribution, trends, and determinants of aetiologies for vaginal discharge, urethral discharge, and genital ulcer in sub-Saharan Africa (SSA).

Methods and findings
We searched Embase, MEDLINE, Global Health, Web of Science, and grey literature from inception until December 20, 2023, for observational studies reporting aetiologic diagnoses among symptomatic populations in SSA. We adjusted observations for diagnostic test performance, used generalised linear mixed-effects meta-regressions to generate estimates, and critically appraised studies using an adapted Joanna Briggs Institute checklist. Of 4,418 identified records, 206 reports were included from 190 studies in 32 countries conducted between 1969 and 2022. In 2015, estimated primary aetiologies for vaginal discharge were candidiasis (69.4% [95% confidence interval (CI): 44.3% to 86.6%], n = 50), bacterial vaginosis (50.0% [95% CI: 32.3% to 67.8%], n = 39), chlamydia (16.2% [95% CI: 8.6% to 28.5%], n = 50), and trichomoniasis (12.9% [95% CI: 7.7% to 20.7%], n = 80); for urethral discharge were gonorrhoea (77.1% [95% CI: 68.1% to 84.1%], n = 68) and chlamydia (21.9% [95% CI: 15.4% to 30.3%], n = 48); and for genital ulcer were herpes simplex virus type 2 (HSV-2) (48.3% [95% CI: 32.9% to 64.1%], n = 47) and syphilis (9.3% [95% CI: 6.4% to 13.4%], n = 117). Temporal variation was substantial, particularly for genital ulcer where HSV-2 replaced chancroid as the primary cause. Aetiologic distributions for each symptom were largely the same across regions and population strata, despite HIV status and age being significantly associated with several infection diagnoses. Limitations of the review include the absence of studies in 16 of 48 SSA countries, substantial heterogeneity in study observations, and impeded assessment of this variability due to incomplete or inconsistent reporting across studies.

Conclusions
In our study, syndrome aetiologies in SSA aligned with World Health Organization guidelines without strong evidence of geographic or demographic variation, supporting broad guideline applicability. Temporal changes underscore the importance of regular aetiologic re-assessment for effective syndromic management.
