Ropinirole patch treatment of nocturnal violent tremor in Parkinson's disease
Authors: Kataoka Hiroshi , Sugie Kazuma 
Published: September 2023

AbstractParkinson's disease (PD) patients experience nocturnal movement linked to primary sleep disorders. We describe a patient with PD who presented with unusual nocturnal tremor. Frequent, violent tremor during sleep is unusual but can occur in PD, and treatment is likely to be difficult. Nocturnal tremor may result from the on–off phenomenon and can be successfully treated using a long‐acting ropinirole patch.
PIECING TOGETHER THE STORY OF A PAIR OF MAKRON’S FRAGMENTED CUPS
Authors: Gill David W. J. , Tsirogiannis Christos 
Published: September 2023

SummaryIn 2022, an Athenian red‐figured cup attributed to Makron was returned to Italy by New York’s Metropolitan Museum of Art. The cup had been acquired in fragments, through purchase and gift, from multiple sources over several years, starting with two fragments from the restorer Fritz Bürki in 1978. A second cup, also attributed to Makron, was acquired in a parallel way. The sources for the fragments from both cups point to galleries collectors and donors – Summa Galleries, Frieda Tchachos, Elizabeth Hecht, and Dietrich von Bothmer – who have been associated with other material that has been repatriated to Italy in recent years. It is suggested that some of the incised ‘signatures’ by Hieron that are found on cups attributed to Makron may have been applied since antiquity.
A meta‐analysis of the placebo response in vitiligo: Causes and consequences for the interpretation of clinical trials
Authors: Speeckaert Reinhart , Speeckaert Marijn M. , van Geel Nanja 
Published: September 2023

AbstractThe current understanding of the placebo response in vitiligo is limited. Nonetheless, it is difficult to compare the outcomes of vitiligo trials if the repigmentation rates in placebo patients vary significantly. We conducted a meta‐analysis of the placebo response in vitiligo trials. Overall, repigmentation rates in patients receiving placebo were 22%, ranging substantially from 0 to 60%. Repigmentation (>25%) was still relatively common for placebo (9.35%), but fell to 5% when >50% improvement was analyzed. Higher frequencies of placebo responses correlated with more repigmentation in the intervention groups. Facial vitiligo and sunlight exposure was linked to higher placebo responses. Roughly estimating the amount of improvement using quartiles (0–25, 25%–50%, 50%–75%, 75%–100% repigmentation) resulted in higher placebo rates compared to other assessment methods. In clinical studies with older patients, the ratio of placebo reactions to treatment responses was higher. This is likely because clinical trials with older patients reported less repigmentation after treatment than studies with younger patients. The percentual difference in affected body surface area during the study period ranged from 6.2% worsening to 17.6% improvement in the placebo groups. This high variability in placebo responses illustrates the need for standardized outcome measures and more head‐to‐head trials in vitiligo.
Impacts of Post Critical Incident Seminar on emergency service personnel: The critical incident–related experiences and psychological state
Authors: Korpela Sanna , Nordquist Hilla 
Published: September 2023

IntroductionPost Critical Incident Seminar (PCIS) is an intervention originally developed by the Federal Bureau of Investigation (FBI) for supporting law enforcement officers who have faced critical incidents (CIs) at work. In Finland, police forces have arranged modified PCIS regularly since 2012, but the first PCIS for emergency service personnel was organized in 2020. PCIS consists of psychoeducation, peer support, and mental health professional support/Eye Movement Desensitization and Reprocessing (EMDR). Previous international studies of PCIS are scarce. Our research question was this: After 6 months, how do emergency service personnel who have participated in the PCIS describe the impacts of PCIS on experiences and psychological state evoked by the CI that was the reason to apply for it?MethodsThe data consisted of individual interviews 6 months after attending the PCIS. The number of participants in this study was 15 (94%). The data was analyzed qualitatively with inductive content analysis.ResultsThe impacts of PCIS on incident‐related experiences and state 6 months afterward were divided into five main categories: social changes, new perspectives and sensations, incident‐related components, future‐oriented processes, and new abilities and actions.ConclusionsPCIS can have multilevel impacts on the experiences and psychological state caused by a CI. These impacts are reflected, for example, in their inner experience, choices, emotions, actions, and relationships with others in different areas of life. As a result of PCIS, the emergency service personnel's relationship with CIs in the past and the ability to function in the future can change. Further study is needed to investigate the long‐term impacts of the PCIS.
A single‐camera telecentric imaging stereo‐digital image correlation system and its application to carotid pulse signal detection
Authors: Chen Chao , Tang Xiaojun , Pan Bing 
Published: September 2023

AbstractCarotid pulse signal (CPS) is one of the most important biomarkers for evaluating cardiovascular risk. To realize easy‐to‐operate and accurate CPS detection, a single‐camera telecentric imaging stereo‐digital image correlation (stereo‐DIC) system is established. The system uses a specially designed colour separation device and a single colour camera attached with a telecentric lens to record images of blue and red colours from different optical paths. By processing the recorded two sub‐channel colour images using regular stereo‐DIC algorithm, full‐field 3D displacements of the skin on the neck directly over the carotid artery are obtained. The maximum fluctuations in the out‐of‐plane displacement direction are extracted as CPS, based on which velocity, acceleration and frequency can be further extracted. The performance of the established system was demonstrated by detecting the pulse signal of a volunteer before and after exercise.

Published: September 2023

AbstractObjectivesTo categorize the fascial planes and the intersections of these fascial planes in the hindlimb of the dog to facilitate preoperative planning for superficial cancers.Study designQualitative anatomical study.Sample populationFour male and five female mixed breed dogs, weighing ~15–35 kg.MethodsSkin and subcutaneous fat were removed, and fascial planes were explored to determine borders and quality. Fascia was categorized as type I (discrete sheets), type II (adhered to thin muscles), type III (adhered to thick muscles), or type IV (associated with periosteum). Digital modification of specimen photographs was performed to map tissues.ResultsDifferences in dogs were noted due to either size or sex but were sufficiently minor to allow mapping. Fasciae of the hindlimb were predominantly type II or III, with type I fascia primarily at the lateral gluteal region, fascia lata, and lateral crus. Type IV fascia was seen at the iliac wing, ischium, patella, tibial tuberosity, medial tibia, distal crus, and pes. Fascia for surgical use was thin or absent at the ischiorectal fossa, femoral triangle, extensor mechanism, medial and distal crus, and pes. Intersections and tissues at the ventral perineum may also pose challenges for maintenance of a deep margin.ConclusionFascial types and integrity of the hindlimb varied with location, with the perineum, cranial stifle, and distal limb presenting the greatest challenges.Clinical significanceThese images may be used to guide both therapeutic decision‐making and intraoperative excision of superficial tumors of the hindlimb and pelvis.
Comparison of Numerical Methods That Predict Wellbore Cement Sheath Integrity
Authors: Wise Jarrett , Nygaard Runar 
Published: September 2023

Abstract
Wellbore leakage is a concern for abandoned oil and gas wells due to greenhouse gas emissions. The leakage mechanisms and resulting integrity are not well understood. Therefore, researchers have used analytical and numerical models to investigate wellbore integrity. An analytical solution, a finite element model without failure mechanisms, and a finite element model with failure criteria were developed and compared. The benefits and shortcomings of each model were discussed, and the different models were compared with three case study wells. The results of this work show that all three numerical models predict debonding between the cement sheath and the casing. However, including the failure criteria in the models proved to be critical in predicting correct stress distributions.

Published: September 2023

Abstract
This study investigated the effect of the methanol–gasoline blend (M15) on the combustion and performance characteristics of a commercial light-duty Bharat Stage-VI (BS-VI) 2020 spark-ignition (SI) engine. The M15 and baseline gasoline (G100) engine tests were performed at a wide range of engine loads and speeds. For the M15 operation, it was ensured that the lambda values matched with the baseline gasoline operation at each engine operating point by changing fuel quantity manually. The combustion characteristics of M15 were quite similar to gasoline at all operating points. Alcohol addition improves octane number and flame speed, which changes the combustion characteristics of the engine, but in this study, the combustion characteristics of M15 fuel were almost identical. It may be due to blending a small fraction of methanol and the engine's high compression ratio, which improved the combustion kinetics. The coefficient of variance of indicated mean effective pressure was slightly lower for M15 than gasoline, except at 1000 rpm, where the charge mixing might not be adequate at low engine speed for M15 due to lower methanol volatility. Engine's brake thermal efficiency improved with M15 fueling by ∼1%, compared to baseline gasoline, though brake-specific fuel consumption deteriorated by ∼6% due to the lower calorific value of M15. Higher combustion stability and possibly lower heat transfer losses, as observed from slightly higher exhaust gas temperature (EGT), might have improved the engine's performance for M15. This study demonstrated that M15 fueling exhibited identical combustion characteristics and higher thermal efficiency than baseline gasoline fueling at similar lambda values in a commercial light-duty BS-VI SI engine.
Probabilistic Bayesian Approach for Delamination Localization in GFRP Composites Using Nonlinear Guided Waves
Authors: Gangwar Akhilendra S. , Joglekar Dhanashri M. 
Published: September 2023

Abstract
Nondestructive evaluation (NDE) techniques that use nonlinear wave–damage interactions have gained significant attention recently due to their improved sensitivity in detecting incipient damage. This study presents the use of finite element (FE) simulation with the experimental investigation to quantify the effects of guided waves’ propagation through multiple delaminations in unidirectional glass fiber-reinforced polymer (GFRP) composites. Further, it utilizes the outcomes of nonlinear interactions between guided waves and delaminations to locate the latter. This is achieved through probabilistic Bayesian updating with a structural reliability approach. Guided waves interacting with delaminations induce nonlinear acoustic signatures that can be quantified by the nonlinearity index (NLI). The study found that the NLI changes with the interrogation frequency, as confirmed by numerical and experimental observations. By using the numerical outcomes obtained from the nonlinear responses, a Bayesian model-based approach with subset simulation is proposed and subsequently used to locate multiple delaminations. The results indicate that both the log-likelihood and log-evidence are key factors in determining the localization phenomenon. The proposed method successfully localizes multiple delaminations and evaluates their number, interlaminar position, width, and type.
Decomposition and Uncoupling of Multi-Degree-of-Freedom Gyroscopic Conservative Systems
Authors: Bulatovic Ranislav M. , Udwadia Firdaus E. 
Published: September 2023

Abstract
This paper explores the decomposition of linear, multi-degree-of-freedom, conservative gyroscopic dynamical systems into uncoupled subsystems through the use of real congruences. Two conditions, both of which are necessary and sufficient, are provided for the existence of a real linear coordinate transformation that uncouples the dynamical system into independent canonical subsystems, each subsystem having no more than two-degrees-of-freedom. New insights and conceptual simplifications of the behavior of such systems are provided when these conditions are satisfied, thereby improving our understanding of their complex dynamical behavior. Several analytical results useful in science and engineering are obtained as consequences of these twin conditions. Many of the analytical results are illustrated by several numerical examples to show their immediate applicability to naturally occurring and engineered systems.
Durability-Enhanced Thermochromic Perovskite Smart Window for Energy-Efficient Buildings

Published: September 2023

Abstract
Thermochromic perovskite smart windows that have recently emerged can dynamically and passively change the solar transmittance as the ambient temperature changes, giving them the potential to contribute to energy saving in buildings. However, thermochromic perovskites can be easily damaged by water and moisture in the ambient air. To solve this problem, in this study, a durability-enhanced thermochromic perovskite smart window is proposed. By integrating an inorganic buffer layer and a hydrophobic nano-silica coating, the new thermochromic perovskite window demonstrates superhydrophobicity with a contact angle of 160° to repel water. And it can maintain a high solar modulation ability (Δτsol &gt; 20%) after a 45-day durability test in an ambient environment with ∼60% relative humidity, representing ∼20 times the lifespan of an unprotected thermochromic perovskite window. This new window also demonstrates an excellent optical performance with a high luminous transmittance of ∼83% in a transparent state, a high solar modulation ability (Δτsol) of ∼24%, and a low haze of ∼30%. Overall, the proposed novel window structure provides an easy and effective strategy to improve the lifespan of thermochromic perovskite, further paving the way for practical applications in energy-efficient smart windows.
The Difference in Blue Water Usage of Meals Prepared at Home Versus Meals Prepared Away From Home
Authors: Sices Schuyler , Wemhoff Aaron P. 
Published: September 2023

Abstract
The global trend of increasing consumption of food prepared away from home (FAFH) versus food prepared at home (FAH) can have environmental consequences such as blue water footprint. This study therefore estimates the difference in blue water usage of FAFH versus FAH. Blue water footprints of individual food items and consumer survey data were combined to obtain overall values for FAFH and FAH consumption. The data suggest that FAFH consumes approximately 258 L per kilogram of food, which is approximately 15% higher than FAH. The difference in water footprint is largely due to an increased consumption protein-based meals in FAFH compared to FAH. However, the gap in water footprint is mitigated by the increased consumption of high water-consuming snacks at home such as nuts and dried fruits, as well as meal ingredients like processed oils. The calculations suggest a much higher water footprint per kcal and per USD in FAH versus FAFH. Finally, nuts and dried fruit are found to have the highest specific water footprint despite a relatively low carbon footprint.
Power Generation Maximization Control Framework for Ocean Current Turbine Farms
Authors: Ondes Ertugrul Baris , Sultan Cornel , VanZwieten James H. 
Published: September 2023

Abstract
In this work, we propose a control framework for farms consisting of ocean current turbines (OCT). The ocean current turbine systems used in this farm are tethered to the ground of the ocean, and their depth can be adjusted online based on the maximum ocean current power available. To maximize the average power generated by the farm, the ocean current turbine wake interactions must be taken into account, and also each turbine in the farm should achieve these changes in the position reference with minimum control energy. Considering additional limitations such as keeping the tethering cables away from each other and avoiding collisions between the turbines, an advanced optimization framework is developed to achieve the maximum power generation in a specified region. Tracking of the reference trajectories by the ocean current turbine systems is achieved by model predictive control (MPC). A case study is presented to highlight the significant estimated improvement in the average energy generated by the farm using the proposed framework and control methodology.

Published: September 2023

Abstract
Buildings are one of the major contributors to global greenhouse gas emissions. Decarbonizing building sectors has greatly been emphasized globally. For example, New York state has an aggressive roadmap to decarbonize the building sectors by 2050. To achieve this, electrification of space heating and water heating systems is critical, and it requires energy-efficient and feasible solutions rather than electric coil heating. This study proposes a heat recovery-enabled heat pump technology (i.e., variable refrigerant flow with heat recovery (VRF-HR)) for space heating and domestic water heating and presents a feasibility study of the proposed technology to evaluate decarbonization performance. A computational model is developed to simulate the energy performance of the proposed technology. The model uses a refrigerant circuit box to control refrigerant flows between indoor and heat recovery units for simultaneous space cooling, space heating, and/or hot water generation. A case study for apartment and hotel buildings located in New York City is conducted to demonstrate the feasibility of the proposed technology for decarbonization compared to a conventional system. Building energy simulations are carried out using a whole building energy modeling tool, EnergyPlus. Based on hourly simulation results, the post-process calculation is performed to examine the energy-saving and decarbonization potential by comparing with results from a conventional natural gas-based space and domestic water heating system. Results indicate that the proposed VRF-HR system can effectively achieve building electrification and decarbonization with lowered energy consumption (i.e., about 20% of annual cooling/heating energy savings and 80% of domestic hot water energy savings). Results also show that heat recovery technologies are a remarkable addition to enable electrification and decarbonization effectively.
Numerical Investigation of Thermochemical Energy Extraction in a Moving Packed Bed Oxidation Reactor-Heat Exchanger
Authors: Mishra Ashreet , Korba David , Li Like 
Published: September 2023

Abstract
Moving packed bed heat exchangers (MPBHXs) are becoming an increasingly attractive option for particle-to-sCO2 heat exchangers (HXs) and integrating thermochemical energy storage based on metal oxide redox cycles with concentrated solar power (CSP) systems can provide significant advantages compared to sensible heat storage systems, such as higher energy storage density, higher working fluid (WF) temperature and potentially lower system costs. This work focuses on computational modeling of a shell-and-plate moving bed oxidation reactor-heat exchanger design that utilizes the exothermic oxidation of metal oxide particles under air flow to enhance thermal transport to sCO2 via both sensible and thermochemical heat exchange. A 2D volume-averaged continuum model is developed by coupling the counter-current air-particle flow, interphase heat transfer, thermochemical oxidation reaction, and species transport in the particle channel with sCO2 flow in the WF channel. The counter-flow particle-sCO2 sensible heat exchanger model is verified with previous numerical models in the literature, whereas the transport-reaction model within the particle channel is adopted from previous literature. For the baseline cases with similar geometry, operating parameters, and particle sizes, the total heat transfer for the TCES based HX was 16.71 kW compared to 4.62 kW for sensible only HX. The maximum extent of oxidation at the particle channel outlet was ∼75%, and the sCO2 outlet temperature was 692°C for reactive particles compared to 595°C for inert particles. A parametric study was also conducted to determine the effects of sCO2 and air flow rates on the temperature, extent of reaction, O2 absorption, and total heat transfer of the HXs.

Published: September 2023

Abstract
We present a proof of concept demonstration of solar thermochemical energy storage on a multiple year time scale. We designed and fabricated a 4-kW solar rotary drum reactor to carry out the solar-driven charging step of solar thermochemical storage via metal oxide reduction-oxidation cycles. During the summer of 2019, the solar reactor was operated in the Valparaiso University solar furnace to effect the reduction of sub-millimeter cobalt oxide particles in air at approximately 1000°C. A particle collection system cooled the reduced particles rapidly enough to maintain conversions of 84–94% for feed rates of 2.9–60.8 g min−1. The solar to chemical storage efficiency, defined as the enthalpy of the reduction reaction at 1000°C divided by the solar energy input, reached 20% for an input solar flux of 1400 kW m−2 and a cobalt oxide feed rate of 60.8 g min−1. Samples of the reduced cobalt oxide particles were stored in vials in air at room temperature for more than three years. The stored solar energy was released by reoxidizing samples in air in a benchtop reactor. Measurements of the oxygen uptake by the reduced metal oxide confirm its promise as a medium to store and dispatch solar energy over long durations.
