Published: June 2023

Key Clinical MessagePancreatic pseudocysts are rare in the pediatric population, commonly a result of trauma. Timely diagnosis and adequate management with a multidisciplinary approach are the key to avoid morbidity and mortality. Larger cysts often require surgical intervention.AbstractWe report a case of a 4‐year‐old female child who presented with a massive pancreatic pseudocyst. Pseudocysts >10 cm are at an increased risk of rupture, hence require surgical intervention. Percutaneous external drainage via pigtail catheter was followed by cysto‐gastrostomy due to continuous high output. The postoperative period was uneventful.

Amide Skeletal Elongation via Amino Acid Insertion
Authors: Liu Zhengqiang , Zhou Lei , Liu Wenbo H. 
Published: June 2023

AbstractAmide derivatization is useful to access valuable organic compounds considering the ready availability of molecules containing amide functionality. Current methods to derivatize amide mainly focus on the synthesis of carbonyl‐containing compounds and amines. Incorporating both parts of the initial amide into the new derivatives is rare. Herein, we describe a simple and practical amide derivatization through amino acid insertion to prepare more complex amides. This insertion is applicable to a wide range of amino acids and more importantly, the chiral information is completely conserved during the insertion. Comparison of this insertion strategy with conventional amide synthesis demonstrates the synthetic advantages of this new protocol.
Seasonal employee leadership and turnover intention in the hospitality and tourism industry: Serial mediation model workplace ostracism and work alienation
Authors: Aktürk Cihan , Yeşiltaş Murat 
Published: June 2023

AbstractBased on the Conservation of Resources Theory, this research aims to examine the relationship between seasonal employee leadership (SEL) and turnover intention (TI). The data was obtained by administering a survey to 450 seasonal employees working in 15 five‐star hotels in Antalya. The findings revealed that SEL reduces TI, which is an important problem for the tourism industry. The study results show that SEL was negatively related to workplace ostracism (WO) and work alienation (WA) and TI. Further, the findings show the serial mediating effect of WO and WA between SEL and TI. The study makes useful recommendations to managers to eliminate ostracism, curb the feeling of alienation and decrease TI.

Published: June 2023

AbstractMitigating CO2 emissions from industries and other sectors of our economy is a critical component of building a sustainable economy. This paper investigates two different methanol synthesis routes based on CO2 utilization (CO2 capture and utilization [CCU], and tri‐reforming of methane [TRM]), and compares the results with the conventional methanol production using natural gas as the feedstock (NG‐MeOH). A comprehensive techno‐economic analysis (TEA) model that includes the findings of the life cycle assessment (LCA) models of methanol production using various CO2 utilization pathways is conducted. Economic analysis is conducted by developing a cost model that is connected to the simulation models for each production route. Compared to the conventional process (with a GHG emission of 0.6 kg CO2/kg MeOH), the lifecycle GHG reduction of 1.75 and 0.41 kg CO2/kg MeOH are achievable in the CCU and TRM pathways, respectively. Furthermore, the results indicate that, under current market conditions and hydrogen production costs, methanol production via CO2 hydrogenation will result in a cost approximately three times higher than that of the conventional process. The integrated TEA–LCA model shows that this increased cost of production equates to a required life cycle GHG reduction credit of $279 to $422 per tonne of CO2 utilized, depending on construction material and selected pathway. Additionally, when compared to the CO2 hydrogenation route, the tri‐reforming process (TRM‐MeOH) can result in a 42% cost savings. Furthermore, a minimum financial support of $56 per tonne utilized CO2 will be required to make the TRM‐MeOH process economically viable.

Published: June 2023

Comprehensive SummaryAdvanced radiative cooling materials with both heating and cooling mode is of pivotal importance for all‐season energy‐saving in buildings. In this work, we report the design and fabrication of bacterial cellulose‐based Janus films (J‐BC) with radiative cooling and solar heating properties, which were developed by two‐step vacuum‐assisted filtration of modified MXene‐doped bacterial cellulose and modified silicon nitride (Si3N4)‐doped bacterial cellulose, followed by hot‐pressing and drying treatments. The as‐prepared J‐BC films show a unique Janus structure where modified MXene nanosheets and cellulose nanofibers are on the bottom surface, and modified silicon nitride (Si3N4) nanoparticles and cellulose nanofibers are on the top surface. The radiative cooling effect of J‐BC films is enabled by the Si3N4‐doped bacterial cellulose due to the high mid‐infrared emissivity of Si3N4 nanoparticles, which shows a high solar reflection of ~98.1% and high emissivity of ~93.6% in the atmospheric transparency window (8—13 μm). Thanks to the enhanced photothermal conversion of the modified MXene nanosheets, a reduced solar reflection (6.6%) and relatively low thermal emissivity in the atmospheric window (71.4%) are achieved, making sure the solar heating effect of J‐BC films. In the outdoor tests, J‐BC films achieve a sub‐ambient temperature drop of ~3.8 °C and an above‐ambient temperature rise of ~14.2 °C. Numerical prediction demonstrated that the J‐BC films with dual modes have great potential of all‐season energy saving for buildings and a corresponding energy‐saving map in China is also created. The work disclosed herein can provide an avenue for the shaping of advanced radiative cooling materials for emerging applications of personal thermal management, sustainable energy‐efficient buildings, and beyond.
Economic and feasibility analysis of brownfields into brightfields by solar energy
Authors: Chen Ying‐Chu 
Published: June 2023

AbstractThis study evaluated the costs and feasibility of building photovoltaic (PV) energy systems on brownfields in four localities in Taiwan. Brownfield remediation was assessed as ex situ excavation, in situ physicochemical treatment, and phytoremediation. The localities in tropical Southern Taiwan would have a higher feed‐in tariff revenue (US$0.1750 kWh–1) due to a higher daily power generating efficiency from sunlight. The capital cost including the PV modules would be approximately US$27.1–US$440 million, but the 20‐year operation and maintenance costs would be much lower. The residual value of the PV systems would be significant (US$0.03–$4.7 million) if the systems are recycled at the end of their lifetime. The total revenues from building PV systems on remediated brownfields would be US$463 241–$7 597 138, with a payback period of less than 13 years. The benefit/cost ratios of the PV systems would be between 1.26 and 1.86 depending on the remediation costs. The payback period would be extended to 16 years with a US$0.61 million ha–1 net present value if the brownfields are remediated by phytoremediation. The sensitivity analysis found that the capital costs, feedback fund, and daily power generating efficiency would be US$343 097 for every 1% of the total revenue. It is worth building a PV system if the cost of land is higher than the net present value of the PV system.
Attachment and alexithymia predict emotional–behavioural problems of institutionalized, late‐adopted and community adolescents: An explorative multi‐informant mixed‐method study
Authors: Muzi Stefania , Pace Cecilia Serena 
Published: June 2023

AbstractObjectiveCompared to community adolescents (COM), adolescents placed in residential care (RC) or late adopted (LA) appear to show more emotional–behavioural problems. They also appear vulnerable in variables linked to emotional–behavioural problems, such as insecure–disorganized attachment and alexithymia. This study employs a mixed‐method multi‐informant approach to (1) compare adolescents placed in RC, LA and COM in emotional–behavioural problems, attachment and alexithymia and (2) investigate relationships and interplay of attachment and alexithymia concerning emotional–behavioural problems in these three groups.MethodParticipants were 174 adolescents (50 RC, 33 LA and 91 COM; Mage = 15, 53% boys and 47% girls). Adolescents' internalizing and externalizing problems were assessed through both caregiver‐reported and self‐reported questionnaires, while attachment and alexithymia were assessed with a mixed method, using interviews and self‐report questionnaires.ResultsThe results showed RC adolescents as more vulnerable in all variables, while LA and COM did not differ. Accounting for the group, attachment and alexithymia cumulatively predicted 25–43% of internalizing problems, and 19–43% of externalizing problems depending on the method of assessment or problems' informant (all p < 0.01). Alexithymia was both an independent predictor and interacted with preoccupied attachment in predicting internalizing problems, while no predictors were isolated for externalizing ones, and the group never indicate an effect on problems' rates.ConclusionsThe authors discuss the utility to maintain a research focus on attachment and alexithymia, also suggesting future directions of research. A need to determine potential distortions of results because of problems' informant and method of assessment is also highlighted.

AbstractEffective cleavage and functionalization of C(OH)−C bonds is of great importance for the production of value‐added chemicals from renewable biomass resources such as carbohydrates, lignin and their derivatives. The efficiency and selectivity of oxidative cleavage of C(OH)−C bonds are hindered by their inert nature and various side reactions associated with the hydroxyl group. The oxidative conversion of secondary alcohols to produce aldehydes is particularly challenging because the generated aldehydes tend to be over‐oxidized to acids or the other side products. Noble‐metal based catalysts are necessary to get satisfactory aldehyde yields. Herein, for the first time, the efficient aerobic oxidative conversion of secondary aromatic alcohols into aromatic aldehydes is reported using non‐noble metal catalysts and environmentally benign oxygen, without any additional base. It was found that CuI−1,10‐phenanthroline (Cu−phen) complex showed outstanding performance for the reactions. The C(OH)−C bonds of a diverse array of aromatic secondary alcohols were effectively cleaved and functionalized, selectively affording aldehydes with excellent yields. Detailed mechanism study revealed a radical mediated pathway for the oxidative reaction. We believe that the findings in this work will lead to many explorations in non‐noble metal catalyzed oxidative reactions.
Simulated annealing‐based high‐level synthesis methodology for reliable and energy‐aware application specific integrated circuit designs with multiple supply voltages
Authors: Dilek Selma , Tosun Suleyman , Cakin Alperen 
Published: June 2023

SummaryIntegrated circuits have become more vulnerable to soft errors due to smaller transistor sizes and lower threshold voltage levels. Energy reduction methods make circuits more error‐prone since even the smallest amounts of environmental radiation can cause a bit flip. Furthermore, redundancy‐based error detection and correction methods induce higher costs and area overhead. Thus, several conflicting parameters may need to be considered during embedded system design (e.g., area, performance, energy, and reliability). High‐level synthesis (HLS) is the most practical design step to consider all these parameters as complexity increases at lower levels. HLS can be viewed as a multi‐objective optimization problem of finding a set of Pareto‐optimal designs, allowing designers to choose the ones that best fit the requirements. Moreover, the number of synthesis options superlinearly affects the search space growth, necessitating efficient optimization methods. In this study, we propose simulated annealing (SA)‐based HLS methods for multi‐Vcc application‐specific integrated circuit design, aiming to optimize energy consumption and reliability under the area and latency constraints. Furthermore, we use duplication to improve design reliability as much as the constraints allow. We compared our methods against genetic algorithm (GA)‐based and integer linear programming (ILP)‐based methods and showed their effectiveness in finding optimum or near‐optimum results in a short running time. SA‐based methods achieved up to 21.20% reliability improvement on average and up to 38% energy reduction on average, while preserving the reliability value against the GA‐based metaheuristic counterpart under joint reliability and energy optimization on four HLS benchmarks.

AbstractThe study of carnivores' diet is a key component to enhance knowledge on the ecology of predators and their effect on prey populations. Although molecular approaches to detect prey DNA in carnivore scats are improving, the validation of their accuracy, a prerequisite for reliable applications within ecological frameworks, is still lagging behind the methodological advances. Indeed, variation in detection probability among prey species can occur, representing a potentially insidious source of bias in food‐habit studies of carnivores. Calibration of DNA‐based methods involves the optimization of specificity and sensitivity and, whereas priority is usually given to the former to avoid false positives, sensitivity is rarely investigated so that false negatives may be largely overlooked. We conducted feeding trials with captive wolves (Canis lupus) to validate a nanofluidic array technology recently developed for the detection of multiple prey species in scats. Using 371 scat samples from 12 wolves fed with a single‐prey diet, the sensitivity of our nanofluidic array method varied between 0.45 and 0.95 for the six main ungulate prey species. The method sensitivity was enhanced by using multiple markers per species and by a relatively low threshold of number of amplifying markers required to confirm a detection. Yet, at least two markers should be used to avoid false positives. By acknowledging sources of bias in sensitivity to reliably interpret the results of DNA‐based dietary methods, our study highlights the relevance of feeding experiments to optimally calibrate the relative thresholds to define a positive detection and investigate the occurrence and extent of biases in sensitivity.
An experimental study of the impact of liquefaction‐induced displacement on buried pipelines for buildings
Authors: Ko Yung‐Yen , Wang Hung‐Wei , Jheng Kun‐Yan 
Published: June 2023

AbstractThis study aimed to investigate the impact of soil liquefaction‐induced displacement on buried pipelines critical to the serviceability of buildings, including those for potable water and natural gas. The emphasis was on the service lines connecting distribution mains and buildings due to their higher vulnerability. Two types of forced displacement tests were conducted on full‐scale physical models of buried service lines. One simulated the uplift or subsidence of distribution mains as the soil surrounding the pipelines is completely liquefied, while the other simulated the building settlement due to partial loss of foundation bearing capacity in various conditions of surrounding soil. The longitudinal strains, deflection, and possible leakage of pipelines were monitored during these tests. The results showed that sufficiently large displacement could cause yielding and pulling out from the joint of the pipe. However, high pipe flexibility and joint strength provided adequate resilience of buried pipelines to these damage modes. The corrugated section of stainless‐steel pipe was also verified to reduce strain in the pipeline. Additionally, when a pipeline was subjected to building settlement, liquefaction of surrounding soil or not led to different strain distribution and deflection along the pipeline. Local buckling of the pipe near the loaded end was induced in non‐liquefied cases due to the combination of forced displacement and soil reaction. These findings give a better knowledge of the resistance performance of buried pipelines against liquefaction‐induced displacement.

Published: June 2023

AbstractThe electrochemical performance of manganese ammonium phosphate (MnAP) intercalated carbon hollow sphere (CS) at four mass variates has been investigated. The XRD, Raman, SEM, and electrochemical studies reveal that only 50 mg of CS strongly intercalating with MnAP (MnAP@CS2) is observed. The half‐cell test has shown the profound pseudocapacitance for 50 mg intercalated MnAP@CS2 hybrid composite (2545 C g−1 @ 1 A g−1 in KI added 2 M H2SO4) and confirms the imminence of optimal mass concentration of CS with MnAP and the effect of KI redox additive towards enhancing the specific capacity. The supercapattery hybrid device (SBHD) using MnAP@CS2 as the positive electrode and as newly synthesized activated carbon (AC) derived from cucumis melo var agrestis as a negative electrode is examined in pure 3 M H2SO4 and in 0.025 M KI/VOSO4 dual redox additive added 3 M H2SO4. The exquisite complacency requisite on specific capacitance (536 C g−1/149 mAh g−1 @ 1 A g−1 @ 20 A g−1), energy density (80 Wh g−1), and capacity retention (89% for 5000 charge‐discharge cycles) have profusely advocating MnAP@CS2 and AC for SBH device applications.
Interspecific competition and productivity in a dryland silage maize/alfalfa intercropping system

Published: June 2023

AbstractCereal–legume intercropping has the potential to reduce the use of nitrogen (N) fertilizer and increase forage yield and quality, however, how to optimize system design to fully realize interspecific complementary and enhance crop production in an annual and perennial crops intercropping was not well understood. This study was conducted to evaluate the interspecific interaction and yield performance of silage maize (Zea mays L.) and alfalfa (Medicago sativa L.) intercropping in response to N management and row arrangement under the rain‐fed conditions on the Chinese Loess Plateau. Five planting arrangements, namely, sole maize, sole alfalfa, and maize and alfalfa intercropping in rows of 1:2 (I12), 2:2 (I22), and 2:4 (I24), were compared over a period of 4 years (2018–2021). Two N‐levels (150 and 90 kg N ha−1) were applied to maize in each planting arrangement. Our results show that maize was the dominant species in 2018. In the next 3 years (2019–2021), maize was outcompeted by alfalfa during the first and second cuts of alfalfa, and complete recovery growth of maize was recorded at the third cut. The interspecific competition of I24 was less severe, resulting in a higher yield than I12 and I22. Although the reduction of N application reduced the biomass and crude protein (CP) yield, it weakened the interspecific competition and substantially increased the land equivalent ratio (LER). I24 under low N yielded more than sole cropping, with the LER based on biomass and CP yield of 1.01–1.12 and 1.08–1.18, respectively. In addition, I24 had the highest net revenue of 24,251 ¥ ha−1 on average. Therefore, maize/alfalfa intercrop with a higher alfalfa proportion and a wide strip arrangement (I24) in combination with low N application could alleviate interspecific competition and improve forage production, which is suggested for our study region and similar dryland farming areas worldwide. Maize/alfalfa intercropping provides a basis for grain and livestock mixed farming and helps to improve food supply and resilience of the farming system.

Published: June 2023

AbstractControlling Salmonella in poultry processing continues to be important to processors and consumers. Cetylpyridinium chloride (CPC) has proven to be effective in vitro in controlling Salmonella. This study evaluated the recovery of Salmonella after overnight storage in 4°C filter‐sterilized carcass rinsate containing CPC from 0.44 to 909 ppm (μg/mL). Ten Salmonella serotypes (18 strains), of which 6 serotypes are commonly isolated from poultry products, were grown in Bacto‐Tryptic Soy Broth overnight at 37°C. Serial dilutions of a CPC/propylene glycol solution were prepared in 24‐well tissue culture plates containing filter‐sterilized carcass rinsate. Approximately 107 cfu/mL of each Salmonella serotype was added to the appropriate wells. Inoculated plates were stored overnight at 4°C. After storage, triplicate plates of brilliant green agar with sulfapyridine (BGS) were surface inoculated with 10 μL of the contents for each well, streaked for isolation, and incubated at 37°C for 24 h. Three replications were conducted. The presence of typical colonies on BGS plates was recorded as growth and verified through biochemical and serological testing. Of the serotypes chosen, Salmonella Kentucky, Dublin, and Enteritidis were the least resistant to CPC with a median minimum inhibitory concentration (MIC) of 14.22 μg/mL (range from 3.55 to 56.88 μg/mL); S. Typhimurium demonstrated a median MIC of 114.00 μg/mL (range from 28.44 to 114.00 μg/mL). Residual CPC potentially remaining attached to a carcass or in the weep after processing could potentially alter which Salmonella serotype is recovered from a carcass rinse due to different growth patterns during regulatory testing, with a potential for more virulent strains not to be recovered.
