AbstractBackgroundNonsurgical aesthetic improvement of the nose with hyaluronic acid (HA) fillers is becoming increasingly popular but comes with important safety considerations.AimsTo assess the safety and effectiveness of the standardized “five‐point liquid rhinoplasty” approach.MethodsThis was a retrospective, single‐center analysis of consecutive adult patients undergoing nonsurgical aesthetic treatment of the nose. All had one of the three main indications (insufficient nasal projection, nasal hump, or deep glabella) and were injected using HA fillers with high elastic modulus. Treatments were given using some or all of the injection points of the “five‐point liquid rhinoplasty” technique: P1 (nasal tip, 0.2–0.3 ml supracartilaginous); P2 (nasal root, 0.1–0.2 ml supraperiostal); P3 (cartilaginous dorsum, 0.1–0.2 ml supracartilaginous/supraperiostal); P4 (subnasal, 0.1–0.2 ml supraperiostal); and P5 (nasal alar, 0.1–0.2 ml per side supraperiostal). The risk of complications was minimized by injecting deep and staying in the midline as far as possible.ResultsTwenty patients were enrolled (n = 15 female [75%]; mean age: 37.8 ± 11.7 years). The mean volume of filler used was 0.66 ± 0.35 ml per patient. Nineteen subjects (95%) said they were “very satisfied” with results, and the physician was also “very satisfied” with outcomes in 19 patients (95%). Two individuals experienced hematoma, which was managed conservatively; there were no other significant complications.ConclusionsThe “five‐point liquid rhinoplasty” is a simple and effective method designed to maximize safety. It offers a good alternative to surgery in selected patients.

AbstractOvarian cancer is the most lethal gynecological cancer and can recur in most cases. Surgery is an option for recurrent ovarian cancer. Parasitic infestation disseminated in an immunocompromised host can be fatal. The case is here presented of a female patient diagnosed with early‐stage ovarian cancer. Chemotherapy was initiated for treatment. At the follow‐up examination, masses in the liver suggestive of recurrence were detected on positron emission tomography computed tomography. Surgery was performed. A Strongyloides stercoralis infestation mimicking relapsing ovarian cancer in the liver was diagnosed.
A continuous model of strong and weak ties
Authors: Griffith Alan 
Published: August 2022

AbstractWhen individuals interact in a network, links are often asymmetric and of varying intensity. I study a model whereby networks emerge from agents maximizing utility from continuous linking decisions and self‐investment. The joint link surplus function allows arbitrary, bounded heterogeneity in the benefit to forming links. Under decreasing returns to scale in link surplus, the set of Nash equilibria is well‐behaved. In contrast, with constant or increasing returns to scale, heterogeneity and returns to self‐investment limit the set of Nash equilibria. This model rationalizes equilibrium networks in which individuals simultaneously hold ties that are asymmetric and of varying intensity.

AbstractQuestionsPollen traits (e.g., size, wall thickness, number of apertures) have been suggested to be relevant in terms of pollination mechanisms and the ability of the male gametophyte to withstand desiccation. We examined the spatiotemporal distribution of pollen traits related to dispersal (ornamentation and dispersal unit) and desiccation tolerance (wall thickness, presence of furrows and pores and pollen size). Specifically, we address two questions: how are the pollen traits distributed in relation to different levels of aridity? And, how did the pollen trait composition change with changing past environmental conditions?LocationLaurel forests of La Gomera and Tenerife (Canary Islands).MethodsWe used pollen rain from 19 forest plots on an elevational gradient of 1050 m and all laurel forest types (cold, dry, humid and ridge crest) to quantify pollen trait composition using community‐weighted means. In addition, we used fossil pollen to examine the composition of pollen traits over 9600 years in response to known intervals of regional past climate change.ResultsOur results demonstrated increased prevalence of desiccation tolerance‐related pollen traits over drier areas of the laurel forest distribution. We also found increased prevalence of rich pollen grain ornamentation in the core of the laurel forest distribution. Holocene pollen functional diversity increased during a trend towards drier conditions as did the proportion of pollen grains with apertures and thicker walls to indicate desiccation tolerance.ConclusionsOur study provides the first step towards understanding the role of pollen traits when quantifying the dynamics of different plant communities.

AbstractIntroductionPrematurity and retinopathy of prematurity (ROP) are associated with altered corneal shape and reduced visual acuity in childhood, but their long‐term effects on corneal shape in later life are still unclear. This study evaluated whether prematurity and related perinatal factors are associated with corneal aberrations in adulthood.MethodsThe Gutenberg Prematurity Eye Study (GPES) is a cohort study using Scheimpflug imaging of the cornea. Associations were assessed between corneal Zernike aberrations and gestational age (GA), birth weight (BW), BW percentile, ROP occurrence, ROP treatment and other perinatal factors using univariate and multivariable linear regression analyses.ResultsThis study involved 444 eyes of 256 individuals born preterm (aged 28.1 ± 8.4 years, 146 females) and 231 eyes of 132 individuals born full‐term (aged 29.8 ± 8.9 years, 77 females). Multivariable analyses revealed an association between corneal higher‐order aberrations and lower birth weight percentile (B = −0.001, p < 0.001) as well as ROP treatment (B = 0.120, p = 0.03). Corneal lower‐order aberrations were also associated with lower birth weight percentile (B = −0.004; p = 0.001) and ROP treatment (B = 0.838, p = 0.01) but not with ROP occurrence. Increased corneal aberrations were correlated with lower visual acuity and the spherical equivalent refractive error.ConclusionsPerinatal factors, particularly low birth weight percentile and ROP treatment lead to a more irregular corneal shape in adulthood, thereby reducing optical image quality and potentially contributing to reduced visual acuity and altered refractive error.
Trichloroisocyanuric Acid, A Swimming Pool Disinfectant: New Developments and Role in UV‐Induced Skin Inflammation†
Authors: Chhabra Gagan , Ahmad Nihal 
Published: August 2022

AbstractThis article is a highlight of the paper by Snell et al. in the current issue of Photochemistry and Photobiology (Snell et al. Photochem. Photobiol. 2022). The authors utilized an organotypic human skin model and transgenic SKH‐1 mice to determine the oxidative stress response induced by topical treatment of trichloroisocyanuric acid (TCIC), a common disinfectant used in swimming pool. Additionally, they determined molecular mechanisms associated with topical TCIC pretreatment followed by ultraviolet (UV) radiation exposure. This work provides the first example that cutaneous delivery of TCIC significantly increases UV‐induced skin inflammation, suggesting a previously unidentified potential of TCIC. If translatable to human skin, these findings could be important for human skin health implications.
Fitting Multivariate Multilevel Models under Informative Sampling
Authors: Silva Pedro Luis do N. , Moura Fernando Antônio da S. 
Published: August 2022

AbstractA model-dependent approach for multivariate multilevel normal modelling that accounts for informative sampling of group and unit level population elements is developed. The approach involves extracting the multilevel model holding for the sample data, given the selected sample, as a function of the corresponding population model and the sample selection probabilities, and then fitting the resulting sample model using Bayesian methods. A model-based simulation study is carried out to study the performance of our approach under one scenario motivated by a Brazilian nationwide proficiency assessment exercise. Results indicate that our approach enables improved inference under the informative sampling considered.
Issue linkage versus ringfencing in international agreements*
Authors: Long Ngo Van , Richardson Martin , Stähler Frank 
Published: August 2022

AbstractIssue linkage is often regarded as a means to enhance international cooperation in the presence of a sovereignty constraint. This constraint means a country can leave an agreement whenever it likes, if the perceived gains from leaving are larger than the gains from staying in the agreement. We set up a model of international agreements in which future gains from cooperation are uncertain, and it is bad realizations that can lead to exit. In this environment, we show that ringfencing dominates issue linkage, even in the absence of complementarities between separate issues, if the degree of uncertainty is sufficiently large.
Sovereign anxiety in Myanmar: An emotional geopolitics of China's Belt and Road Initiative

Published: August 2022

AbstractGeographers have increasingly attended to the role of emotion in geopolitical encounters and the geopolitics of cross‐border infrastructure projects. While scholars have theorised fear as an emotion produced by elite geopolitical discourses and encounters between bodies, we know much less about how infrastructure's materialities provoke fear and anxiety. Furthermore, key distinctions between anxiety – or a psychological state of insecurity and unease – and fear, which is attached to a specific target object, are still not fully understood. Focused on the uncertainties over China's Belt and Road Initiative (BRI), we develop the concept of sovereign anxiety – a generalised condition of unease over the security of one's political community – to account for how the BRI generates not only the hard materials of infrastructure (e.g., roads, dams and pipelines), but also the social practices of affect and emotion. Sovereign anxiety, we argue, is heightened by the absence of transparency over China's infrastructure investments in Myanmar. In this paper, we trace how sovereign anxiety is variously experienced and grounded in residents' observations, personal biographies, social histories, and sense of community belonging. We also identify three themes by which fears of the BRI are articulated: relations, roads, and resources. This article contributes an emotional geopolitics perspective to grounded studies of the BRI, while also demonstrating the geopolitical significance of attending to the emotional lives of infrastructure in relation to the BRI and beyond.
Why the majority of on‐site repeat donor deferrals are completely unwarranted…
Authors: Janssen Mart P. 
Published: August 2022

AbstractBackgroundOn‐site deferral for low hemoglobin (Hb) is common in most countries and deferral rates commonly vary between 1% and 20%. Blood banks continuously strive to reduce deferral rates as these imply an immediate loss of products, a waste of materials, a waste of staff and donor time, and potential loss of donors. Despite many efforts, the main cause of donor deferral—the variability in hemoglobin measurement outcomes—remains largely unaddressed.Study Design and MethodsRepeated hemoglobin measurements obtained at donor intake were used to estimate the variability in measurement outcomes (measurement variability). This information is incorporated in a new algorithm for donor deferral where the mean hemoglobin level of a donor is used to determine both donor eligibility and the deviance of individual measurement outcomes. The algorithm was tested on a cohort of new Dutch donors that started between 2012 and 2022 to evaluate its impact on the donor deferral rate.ResultsHistorical data from 439,376 new donors with a deferral rate of 5.3% were analyzed by applying the new donor deferral algorithm. It was found that 92% of all deferrals were unnecessary as Hb levels were within the range of expected measurement variability. Contrarily, it appeared that 460 donors (0.10%) made 704 donations (0.06%) whilst not complying with donor eligibility criteria.DiscussionNot accounting for measurement variability can be shown to not only result in unnecessary on‐site deferrals but also results in donations by donors that can be shown not to comply with the legally required minimum Hb levels.
Evidence for the in vivo existence and mobilisation of myeloid angiogenic cells and pericyte‐like cells in wound patients after skin grafting

AbstractMyeloid angiogenic cells (MACs) and pericyte‐like cells, derived from peripheral blood mononuclear cells (MNCs) by in vitro culturing, are suggested as relevant cell types for angiogenesis and tissue repair. However, the in vivo existence and relevance of these cells has so far remained unknown. Our aim was thus to study, if MACs and pericyte‐like cells exist in circulation during the wound healing of skin graft patients, and to evaluate the cellular features of wound repair. MNCs were isolated from blood samples of healthy controls (n = 4) and patients with a traumatic full thickness skin defect (n = 4) before skin grafting and on postoperative days 1 and 6. The numbers of circulating CD14+CD45+CD31+CD34− MACs and CD14+CD45+NG2+ pericyte‐like cells were assessed by flow cytometry, and gene expression of various pro‐angiogenic factors was analysed by qPCR. Wound bed biopsies were taken on postoperative days 6 and 14, and MAC (CD31, CD14 and CD45) and pericyte‐related markers (NG2 and PDGFRβ) were histologically studied. MACs and pericyte‐like cells were detected in both healthy controls and in patients. Before reconstruction, on average 18% of all circulating MNCs represented MACs and 2% pericyte‐like cells in wound patients. Number of MACs significantly increased 1.1−1.7‐fold in all patients 1 day after skin grafting (p < 0.01). In addition, histological analysis demonstrated effective vascularization of skin grafts, as well as presence of pericytes, and CD14 and CD45 expressing myeloid cells during wound healing. In conclusion, our data shows, for the first time, the presence and mobilisation of MACs and pericyte‐like cells in human circulation.

Published: August 2022

Abstract
Solid oxide fuel cells (SOFCs) generate electricity with high quality waste heat which if harnessed and used as energy source for vapor absorption refrigeration systems (VARS) will address the emission issues related to refrigerated transport infrastructure. The temperature range of the heat source required at the desorber of the VARS is between 120 °C and 200 °C, while SOFCs cathode exhaust heat temperatures are 600 °C and above. Therefore, an internally finned double pipe heat exchanger (DPHX) was used in this study with thermal oil as the coupling fluid to experimentally couple the SOFC cathode exhaust heat with the VARS indirectly. The experimental setup mimics a 5 kWe SOFC stack. Results showed that 1.84 kW of heat was recovered at a cathode exhaust flowrate of 24.64 L s−1 resulting in a heat exchanger effectiveness of 12.22% and overall heat transfer coefficient of 60.15 W m−2 K−1. The recovered 1.84 kW of heat are able to power a single effect VARS on board a small, refrigerated truck to supply 1 kW of cooling load. Results also revealed an exchanger effectiveness and overall heat transfer coefficient increase by 70.2% and 19.4%, respectively, at a reduced exhaust flowrate of 7.347 L s−1. Further improvement of 81.1% and 39.22%, respectively, of exchanger effectiveness and overall heat transfer coefficient was achieved at 4.653 L s−1 exhaust flowrate.
5 μm Level Long Photon Tunneling Distance in Near Field Thermal Radiation Through Metallic Patterns With/Without Dielectric Structures
Authors: Wen Sy-Bor , Jakkinapalli Aravind 
Published: August 2022

Abstract
By integrating wave-type analysis and fluctuation-dissipation theorem, the enhancement of photon tunneling distance in near field thermal radiation through metallic nanopatterns with/without dielectric structures is theoretically studied. When metallic patterns are in the immediate proximity of the conductive emitter, substantial thermal electric enhancement at surface plasmon frequency is observed between the metallic patterns and the emitter when the periodicity of the thermal electric field along the emitter surface is around integer times of the period of the metallic patterns. The mechanism of field amplification is similar to Fabry–Perot type resonance between two reflecting surfaces. The strong thermal electric field from resonance allows long-distance photon tunneling observed in near field radiation at a ∼5 μm separation distance when the same metallic patterns are placed on the collector surfaces. This value is nearly 50 times longer than that with bared emitter surfaces. This long-distance photon tunneling can also happen at a broader range of parallel wavenumbers (i.e., not determined by the period of the metallic patterns) at the surface plasmon frequency when the periodic metallic patterns' sizes are different each period. However, increasing the range of parallel wavenumbers in long-distance photon tunneling with this approach can reduce the strength of photon tunneling. The reduced tunneling strength can be brought up by attaching high refractive index dielectric resonators on top of the metallic patterns. The dielectric resonators on top of the metallic patterns show additional Mie-type resonance when displacement current is induced at the interface between the metallic patterns and the high refractive index dielectric. The higher intensity long-distance photon tunneling with a broad range of parallel wavenumbers can be valuable in harvesting the high intensity and high quality near field radiative energy with engineering feasible micron level vacuum gaps.
Peculiarities of Convective Heat and Mass Transfer in Magnetic Nanofluids
Authors: Suslov Sergey A. 
Published: August 2022

Abstract
Heat transfer enhancement due to thermomagnetic convection arising in nonisothermal electrically nonconducting ferrofluids placed in an external magnetic field is reviewed with an emphasis on realistic applications. It is shown that due to a complex composition of such fluids numerous internal physical processes can lead to directly opposite heat transfer trends. Physical factors influencing such processes are identified. It is concluded that while the complexity of such mechanisms makes designing ferrofluid-based heat exchangers a delicate task when done correctly, it ensures manyfold improvement of heat removal characteristics of such devices compared with their natural convection counterparts. This short review aims to provide a concise starting-point summary of ferrohydrodynamic effects and processes that need to be taken into account when designing practical applications.
The Dawn of the Study of Motor Timing: Wilhelm Camerer (1866) and Karl von Vierordt (1868) on the Time Course of Voluntary Movements
Authors: Wearden John H. 
Published: August 2022

This article discusses material from the doctoral thesis of Wilhlem Camerer, which was devoted to the topic of the timing of voluntary movements, and appeared in 1866, thus being one of the earliest studies of any aspect of time perception. It was conducted under the supervision of Karl von Vierordt, at the University of Tübingen in Germany. The data reported come from Camerer’s attempts to make a movement over a distance of about 65 mm, either by flexion or extension of his arm, with the behavior recorded via a kymograph, and measured from its trace. Most of his data come from his attempts to make movements at a constant speed, with the speed varying from one trial to another from 5 to 60 mm/s, but he also conducted a study where the movement was intended to be accelerated or decelerated during the trial. In general, when extension movements were intended to be performed with constant speed, a gradual increase in movement speed usually occurred throughout the movement duration. For flexions the opposite occurred, albeit less clearly. Camerer linked the apparent distortions of speed to Vierordt’s experiments on the perception of time and his thesis contains what is probably the first mention of Vierordt’s Law, the proposition that short times are judged as longer, and long times as shorter, than they really are.
