AbstractA comprehensive evaluation of the ecological cost of urban expansion is crucial for preventing ecosystem degradation and improving ecosystem governance. However, the indirect impacts of urban expansion through cropland displacement are grossly underestimated, particularly the spillover effects on distant regions. This study proposed a telecoupling framework for the total indirect ecological losses (TIEL) of urban expansion. It was divided into the near losses (NIEL) and distant losses (DIEL), depending on whether cropland displacement occurs inside or outside the region. An inter‐provincial network of DIEL can also be constructed by ecological impact embodied in food trade with other regions. We found that approximately 80% of urban expansion occurred on croplands, which caused indirect loss of 86,586 km2 of ecological land through cropland displacement in China during 2000–2019. The total indirect ecological losses were 8.4 times greater than direct losses at the average of all provinces. Food trade induced more serious indirect ecological losses owing to the higher yield difference between encroached cropland import regions and new cropland in export regions. The proportion of DIEL in TIEL was more than 50% in developed regions such as Beijing, Shanghai, Tianjin, and Jiangsu. The distant impacts of urban expansion in the eastern coastal provinces were mainly transferred to north‐eastern China and the rest of the world. This study identified the teleconnection between local urban development and distant environments and infromed inter‐regional ecological compensation policies to mitigate regional inequalities.

AbstractObjectiveWhat are the electrogustometer's (EGM) validity, reliability, and diagnostic accuracy in assessing taste sensation in adults compared to other taste tests?Data SourcesPubMed Medline, Elseviers's Embase, and the six databases of Cochrane Library.MethodsWe conducted a systematic search on December 20, 2022, consisting of synonyms for EGM. We considered randomized controlled trials and observational studies with original data for inclusion if they included adults who underwent electrogustometry. Articles were excluded if no analysis regarding validity, reliability, or diagnostic accuracy had been performed or if these analyses could not be performed with the published data.ResultsNineteen articles discussing 18 studies were included for data extraction. The included studies carry a high risk of bias. Overall, the association between a variety of reference taste tests and EGM was moderate or weak with correlation coefficients ranging from −0.51 to 0.40 with one outlier of −0.74 found in one study correlating EGM and taste solutions. Test–retest reliability was good with reported correlation coefficients between 0.78 and 1.0. The sensitivity, specificity, PPV, and NPV of EGM in identifying abnormal taste function varied widely between the four studies on diagnostic accuracy.ConclusionThe included studies in this review lack the required standards regarding study design to draw firm conclusions about the validity, reliability, and diagnostic accuracy of the EGM. Future research is needed to assess these measurement properties. Based on the reported results, we would not recommend using the EGM as a screening test for taste disturbance in clinical practice.Level of EvidenceNA.

Published: July 2023

AbstractWaxes find use as processing aids in filled compounds and polyethylene‐based masterbatches. In such applications, the thermal and physical property changes they impart to the polymer matrix are important. Therefore, this study details results obtained for blends prepared by mixing a Fischer–Tropsch (F–T) wax with a high‐flow linear low‐density polyethylene (LLDPE). The melting and crystallization behavior are studied using hot‐stage polarized optical microscopy (POM) and differential scanning calorimetry (DSC). The calorimetry results are consistent with partial cocrystallization of the two components. The melting and crystallization exo‐ and endotherms for the wax‐ and LLDPE‐rich phases remained separate. However, they change in shape and shift toward higher‐ and lower temperature ranges, respectively. It is found that increasing the wax content delays the crystallization, decreases the overall crystallinity, and reduces the size of the crystallites of the polyethylene‐rich phase. Rotational viscosity is measured at 170 °C in the Newtonian shear‐rate range. The variation of the zero‐shear viscosity with blend composition is consistent with the assumption of a homogeneous melt in which the chains are in an entangled state. Therefore, it is concluded that the wax and LLDPE are, in effect, miscible in the melt and partially compatible in the solid state.
Degeneration of the spectral gap with negative Robin parameter
Authors: Kielty Derek 
Published: July 2023

AbstractThe spectral gap of the Neumann and Dirichlet Laplacians are each known to have a sharp positive lower bound among convex domains of a given diameter. Between these cases, for each positive value of the Robin parameter, an analogous sharp lower bound on the spectral gap is conjectured. In this paper, we show that the extension of this conjecture to negative Robin parameters fails by proving that the spectral gap of double cone domains are exponentially small, for each fixed parameter value.

Published: July 2023

AbstractIn this paper, we continue investigation of the lateral order on vector lattices started in [25]. We consider the complexification of a real vector lattice E and introduce the lateral order on . Our first main result asserts that the set of all fragments of an element of the complexification of an uniformly complete vector lattice E is a Boolean algebra. Then, we study narrow operators defined on the complexification of a vector lattice E, extending the results of articles [22, 27, 28] to the setting of operators defined on complex vector lattices. We prove that every order‐to‐norm continuous linear operator from the complexification of an atomless Dedekind complete vector lattice E to a finite‐dimensional Banach space X is strictly narrow. Then, we prove that every C‐compact order‐to‐norm continuous linear operator from to a Banach space X is narrow. We also show that every regular order‐no‐norm continuous linear operator from to a complex Banach lattice is narrow. Finally, in the last part of the paper we investigate narrow operators taking values in symmetric ideals of compact operators.

Published: July 2023

AbstractThe problem of Reissner–Mindlin–Timoshenko plate systems with nonlinear damping terms is considered. The main result is the existence of global attractors. By showing the system is gradient and asymptotic smoothness via a stabilizability inequality, we establish the existence of global attractors with finite fractal dimension. The continuity of global attractors regarding the parameter in a residual dense set is also proved. The above results allow the damping terms with polynomial growth.
Controlled Ring Opening Metathesis Polymerization of a New Monomer: On Switching the Solvent—Water‐Soluble Homopolymers to Degradable Copolymers
Authors: Mandal Ankita , Pal Subhajit , Kilbinger Andreas F. M. 
Published: July 2023

AbstractA new heterocyclic monomer is developed via simple Diels–Alder reaction which is reluctant to polymerize in dichloromethane (DCM) whereas undergoes facile polymerization in tetrahydrofuran with excellent control over molecular weight (Mn) and dispersities (Đ) using Grubbs' third generation catalyst (G3). The deprotection of the tert‐butoxycarbonyl group from the polymeric backbone yielded a water‐soluble ring opening metathesis polymerization (ROMP) polymer easily. Moreover, in DCM this new monomer copolymerizes with 2,3‐dihydrofuran under catalytic living ROMP conditions to give backbone degradable polymers. All the synthesized polymers are characterized by size exclusion chromatography (SEC) and nuclear magnetic resonance (NMR) spectroscopy. It is believed that this new route to water soluble ROMP homopolymers as well as the cost‐effective and environmentally friendly route to degradable copolymers and block‐copolymers could find applications in biomedicine in the near future.

AbstractTraditional Chinese Medicine fumigation is a traditional treatment and the composition of the air is changed to achieve therapeutic effect. In this study, a new experimental system based on laser‐induced breakdown spectroscopy (LIBS) is developed to online in situ detect the smoke and monitor the influence on air composition by smoke. Atractylodis rhizome, wormwood, and perilla are chosen as samples to test the feasibility and accuracy of this system. Some characteristic lines can be seen in the spectra, and detailed elemental information is obtained. The spectra of three types of smoke were analyzed via an identification system based on principal component analysis, random forest (RF), and support vector machine (SVM). The contribution rate of the first two major components is 81.6% in total. The accuracy of classification by RF reaches 87.5% and SVM realizes a classification accuracy of 91.7%. The innovative and developed system based on LIBS and machine learning is demonstrated having a promising application in online in situ detection of air components and classification of smoke generated by Chinese medicine fumigation.

AbstractThe antennas that share radiators with solar cells are applicable to collect energy and integrate radio frequency functions. In this paper, a solar cell integrated multiband antenna is proposed on the basis of Vivaldi antenna structure. Unlike prior research, it has the capacity to reconfigure working frequencies and radiation performance of the antenna through optical control of the solar cell. The purpose of reconfiguration is achieved by means of two switching diodes placed between the differential Vivaldi radiator and conducted via biasing from the solar cell. The integrated solar cell functions both as part of the radiator and as the biasing source for switching diodes. According to the simulation and measurement results, the antenna performs consistently at around 5 GHz, while the radiation performance can be reconfigured at 1.16 and 3 GHz under illumination. In this way, the proposed antenna can fulfill various functions such as green energy collection, wireless communication, and light detection, which makes it applicable in the Internet of Things for low‐power wireless sensor terminal.

Published: July 2023

AbstractBackgroundCombining carbon ion therapy with on‐bed MR imaging has the potential to bring particle therapy to a new level of precision. However, the introduction of magnetic fields brings challenges for dosimetry and quality assurance. For protons, a small, but significant change in detector response was shown in the presence of magnetic fields previously. For carbon ion beams, so far no such experiments have been performed.PurposeTo investigate the influence of external magnetic fields on the response of air‐filled ionization chambers.MethodsFour commercially available ionization chambers, three thimble type (Farmer, Semiflex, and PinPoint), and a plane parallel (Bragg peak) detector were investigated. Detectors were aligned in water such that their effective point of measurement was located at 2 cm depth. Irradiations were performed using square fields for carbon ions of 186.1, 272.5, and 402.8 MeV/u employing magnetic field strengths of 0, 0.25, 0.5, and 1 T. In addition, the detector response for protons and carbon ions was compared taking into account the secondary electron spectra and employing protons of 252.7 MeV for comparison.ResultsFor all four detectors, a statistically significant change in detector response, dependent on the magnetic field strength, was found. The effect was more pronounced for higher energies. The highest effects were found at 0.5 T for the PinPoint detector with a change in detector response of 1.1%. The response of different detector types appeared to be related to the cavity diameter. For proton and carbon ion irradiation with similar secondary electron spectra, the change in detector response was larger for carbon ions compared to protons.ConclusionA small, but significant dependence of the detector response was found for carbon ion irradiation in a magnetic field. The effect was found to be larger for smaller cavity diameters and at medium magnetic field strengths. Changes in detector response were more pronounced for carbon ions compared to protons.
Stochastic modeling of obesity status in United States adults using Markov Chains: A nationally representative analysis of population health data from 2017–2020
Authors: Huang Alexander A. , Huang Samuel Y. 
Published: July 2023

AbstractImportanceThe prevalence of obesity among United States adults has increased from 34.9% in 2013–2014 to 42.8% in 2017–2018. Developing methods to model the increase of obesity over‐time is a necessity to know how to accurately quantify its cost and to develop solutions to combat this national public health emergency.MethodsA cross‐sectional cohort study using the publicly available National Health and Nutrition Examination Survey (NHANES 2017–2020) was conducted in individuals who completed the weight questionnaire and had accurate data for both weight at the time of survey and weight 10 years ago. To model the dynamics of obesity, a Markov transition state matrix was created, which allowed for the analysis of weight transitions over time. Bootstrap simulation was incorporated to account for uncertainty and generate multiple simulated datasets, providing a more robust estimation of the prevalence and trends in obesity within the cohort.ResultsOf the 6146 individuals who met the inclusion criteria, 3024 (49%) individuals were male and 3122 (51%) were female. There were 2252 (37%) White individuals, 1257 (20%) Hispanic individuals, 1636 (37%) Black individuals, and 739 (12%) Asian individuals. The average BMI was 30.16 (SD = 7.15), the average weight was 83.67 kilos (SD = 22.04), and the average weight change was a 3.27 kg (SD = 14.97) increase in body weight. A total of 2411 (39%) individuals lost weight, and 3735 (61%) individuals gained weight. 87 (1%) individuals were underweight (BMI <18.5), 2058 (33%) were normal weight (18.5 ≤ BMI <25), 1376 (22%) were overweight (25 ≤ BMI <30) and 2625 (43%) were in the obese category (BMI >30).ConclusionUnited States adults are at risk of transitioning from normal weight to the overweight or obese category. Markov modeling combined with bootstrap simulations can accurately model long‐term weight status.
“OCTOPUS”: An Intelligent Tool for Assisted Multidisciplinary ORL Oncology Meetings—Preliminary Study
Authors: Ouattassi Naouar , Azdad Anas , Debaghi Hamza , Zarghili Arsalane , El Amine El Alami Mohamed Nouredine 
Published: July 2023

AbstractCurrent sessions of multidisciplinary team meetings (MDMs) have several limitations, including increased costs and duration, as well as limited discussion time for each case. To address these issues, we have developed a computer application called OCTOPUS, which helps manage the patients' list for MDMs. The application allows for the generation of automatic MDM decisions based on predetermined criteria filled in by the patient's doctor and algorithms that comply with the latest oncology guidelines from the National Comprehensive Cancer Network. These decisions must be validated by the MDM faculty members. In cases of nonagreement or complex cases, the application proposes a “face‐to‐face MDM.” The internal mailing system connects all members and allows for the request of a second opinion regarding pathology or imaging results. Initial results suggest that this ergonomic tool provides more flexibility in time management and improved uniformity in selecting cases that would most benefit from face‐to‐face MDMs.

AbstractThe Children's Oncology Group (COG) Young Investigators (YI) Committee is an administrative committee in which liaisons represent 30 COG committees, and was created to facilitate the integration of YIs into the organization, and prepare them for future COG leadership roles. The mentorship program has mentored over 400 YIs since 2005 and currently has 175 active participants. The COG YI Master Roster is a database YIs can join, which allows them to post their interests and accomplishments to COG leadership, and 321 YIs have already joined this list. The YI Committee has held virtual symposia designed to describe how COG operates and provide guidance on how YIs can reach their goals; over 300 YIs have attended these since 2021 and have consistently rated them as helpful. Through these and other elements of the program, the YI Committee remains committed to developing a future pipeline of new investigators.
The weathering resistance of quaternary High‐density polyethylene (HDPE) composites: Effects of weld lines, formulation and degradation on tensile properties
Authors: Viljoen David , Labuschagné Johan , Kuehnert Ines 
Published: July 2023

AbstractIn this work, the effects of weld lines, additives and the degree of QUV weathering on the tensile behavior of a range of high‐density polyethylene composites with calcium carbonate, stabilizers and a carbon black/SEBS masterbatch are studied. The degree of weathering is characterized using FTIR‐derived carbonyl, double‐bond and carbonate indexes based on curve fitting, to allow for the fairer comparison of specimens with and without calcium carbonate. Weld‐line specimens exhibited more rapid degradation than that seen in the reference specimens, while the exposed surfaces of the specimens degraded more quickly than the unexposed surfaces. ISO G154 Cycle 1 and Cycle 6 weathering protocols were compared. The additives were found to be effective at decreasing oxidative degradation, albeit with reduced effects at higher loadings and in mixed systems. These findings were mirrored in the mechanical properties of the specimens, with the modified specimens even exhibiting broadly improved properties with increasing aging. Elongation at break was most sensitive to weathering, with increasing degradation with increasing weathering across almost all specimens.

Published: July 2023

AbstractBACKGROUNDTobacco bacterial wilt is a typical soil‐borne disease caused by Ralstonia nicotianae, which causes huge losses in tobacco production every year. The crude extract of Carex siderosticta Hance was shown to have antibacterial activity against R. nicotianae during our search, and the natural antibacterial components were sought after using bioassay‐guided fractionation of the compounds.RESULTEthanol extract of Carex siderosticta Hance with the minimum inhibitory concentration (MIC) value of 100 μg/mL against R. nicotianae in vitro. The potential of these compounds as antibactericides against R. nicotianae were assessed. Curcusionol (1), showed the highest antibacterial activity against R. nicotianae with MIC value of 12.5 μg/mL in vitro. In the protective effect tests, the control effect of curcusionol (1) was 92.31 and 72.60%, respectively, after application of 7 and 14 days, at a concentration of 1500 μg/mL, being comparable to that of streptomycin sulfate at a concentration of 500 μg/mL, confirming that curcusionol (1) showed the potential for the development of new antibacterial drugs. RNA‐sequencing, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis confirmed that curcusionol mainly destroys R. nicotianae cell membrane structure and affects quorum sensing (QS) to inhibit pathogenic bacteria.CONCLUSIONThis study revealed that the antibacterial activity of Carex siderosticta Hance makes it a botanical bactericide against R. nicotianae, while curcusionol as lead structures for antibacterial development is obvious by its potent antibacterial activity. © 2023 Society of Chemical Industry.
