Authors: Lieb Robert C. , Lieb Kristin J. 
Published: February 2015

Abstract
This research is based upon a 2013 survey of the CEOs of 15 of the largest third-party logistics companies serving the North American marketplace. The survey is the 20th iteration of this annual study, and it addresses such topics as the major dynamics operating in that marketplace and the opportunities and problems facing 3PLs in that region. It also addresses such issues as the movement toward near-shoring, 3PL actions with respect to environmental sustainability issues, 3PL services to the healthcare industry, and the industry's chronic problems related to finding and retaining talented managers. The CEOs also provide one- and three-year forecasts of company and regional 3PL industry revenue growth, while identifying the major changes they believe will occur in the regional 3PL industry during the next year. The implications of the data to 3PLs and their customers are discussed.
How Standardization Will Balance Sustainability Goals in the Transport Component of Energy Supply Chains:
Authors: Bagby John W. 
Published: February 2015

Abstract
Society will likely intensify demands on all supply chain participants to facilitate attainment of two seemingly conflicting sustainability goals: economic and environmental. Critics argue these goals are stubbornly irreconcilable tradeoffs. However, there is significant evidence of their complementarity. This article discusses how many opposing public-policy forces interact to impose the appearance of daunting contradiction. The policy analysis demonstrated here offers a logical path out of the apparent morass. It is argued that the advantages of standardization for key energy supply chain elements can harmonize these existing and other emerging interests, both foreseeable and unforeseeable. The crude-by-rail controversy illustrates how these standardization matters impact national energy policy.

Published: February 2015

Introduction: The use of psychoactive substances by the student population has been the object of various studies in Brazil. Objective: To determine the prevalence of substance use among students. Methods: Quantitative study with a closed questionnaire based on standardized assessment instruments was developed. It consists of questions related to types of psychoactive substance use, abuse, frequency and duration of use, self-criticism regarding the use, consequences of use in relation to health, and misdemeanors committed under the influence of psychoactive substances. The sample included the participation of 268 students. A total of 183 (68.3%) questionnaires were analyzed, and only those with positive result for substance abuse at some point in life, the remainder, 85 (31%) questionnaires, had negative responses to psychoactive substances. Results: Students’ responses to the two years surveyed indicated that the first psychoactive substance used was alcohol (77.9%), followed by tobacco use (10.9%), and marijuana (7.6%). Of the students surveyed, 145 (79.2%) answered that still make use of psychoactive substances, and the current frequency of use varies from one or more times per week. When asked about the possibility of being or becoming drug addicts, 169 (92.3%) responded that they are not or will not become dependent. Conclusion: The results indicate the high rate of substance use among college students surveyed, and point to their contradiction to consider such psychoactive substances harmful to their health.

ImportanceOral and oropharyngeal cancer have low survival rates, and incidence continues to increase.ObjectiveTo determine whether soluble CD44 and total protein (TP) are useful for monitoring head and neck cancer recurrence, either used in a point-of-care (POC) test or as individual laboratory-based biomarkers.Design, Setting, and ParticipantsThis multi-institutional nonrandomized clinical trial testing a novel diagnostic/screening assay took place across the University of California, San Diego; Johns Hopkins University; the Greater Baltimore Medical Center; New York University; and the San Diego Veterans Affairs Hospital. Patients with newly biopsy-proven, untreated oral cavity and oropharyngeal cancer were enrolled. Patients were enrolled April 2017 to April 2019, and data were analyzed December 2022 to June 2023.ExposurePOC salivary oral rinse test.Main Outcomes and MeasuresOral rinses were collected at pretreatment baseline and 3, 6, 12, and 18 months after completion of therapy; participants were then followed up for 3 years to define disease status. Associations of baseline characteristics with a positive test were evaluated by Fisher exact test. The association of a positive value on the CD44 or TP test with progression-free survival was evaluated in an adjusted multivariable proportional hazards model.ResultsOf 172 patients enrolled, the mean (SD) age was 62.5 (10.2) years, and 122 (70.9%) identified as male. Additionally, 92 patients (53.3%) had never smoked, 99 (57.6%) formerly or currently drank alcohol, and 113 (65.7%) presented with oropharyngeal cancers, which were positive for human papillomavirus in 95 (84.1%). Tumor site was associated with test results at baseline; patients with oral cavity cancer had a higher baseline positive POC test rate (47 of 51 [92.2%]) compared to patients with oropharyngeal cancer (85 of 110 [77.3%]). Using Cox regression models with CD44 or TP level as a time-varying covariate, a higher CD44 level showed a statistically significant association with a higher hazard of recurrence (hazard ratio, 1.06; 95% CI, 1.00-1.12), though the TP level was not statistically significant. In multivariate adjusted analysis, higher CD44 and TP levels were associated with increased hazard ratios of recurrence of 1.13 (95% CI, 1.04-1.22) and 3.51 (95% CI, 1.24-9.98), respectively.Conclusion and RelevanceIn this multi-institutional nonrandomized clinical trial of an assay, posttreatment longitudinal monitoring for elevated salivary CD44 and TP levels using an enzyme-linked immunosorbent assay–based laboratory test identified patients at increased risk of future cancer recurrence. The CD44 and TP rapid POC test holds some promise, but further development is needed for this indication.Trial RegistrationClinicalTrials.gov Identifier: NCT03148665

AbstractTrimethyl phosphite promotes the synthesis of 2,4,5‐trisubstituted 2H‐1,2,3‐triazoles. The protocol developed affords a two‐step method towards triazoles from available reagents. 3,4‐Disubstituted isoxazolones are initially coupled with diazonium tetrafluoroborates. The subsequent reaction is triggered by a single electron transfer from the phosphite to the diazenylisoxazolone under heating or blue LED irradiation at room temperature. The radical anion cascade proceeds via a ring opening/decarboxylation/cyclization sequence. The synthesized triazoles show promising fluorescence in the region from 340 nm to 450 nm with a quantum yield up to 81.6%. The emission energy depends slightly on the substituent nature at the triazole carbon atoms. If an electron‐donor group is introduced into the N2 substituent of the triazole ring, it results in a bathochromic shift of the luminescence energy.

AbstractLithium‐sulfur (Li−S) batteries, recognized as one of the most promising next‐generation energy storage systems, are still limited by the “shuttle effect” of soluble polysulfides (LiPSs) on the cathode and the uncontrolled growth of lithium dendrites on the anode. These issues are critical obstacles to their practical application. Currently, many researchers have addressed these challenges from a unilateral perspective. Herein, we propose bifunctional hosts based on high‐entropy selenides (HE−Se) to simultaneously tackle the persistent problems on both the positive and negative electrodes of Li−S batteries. On the one hand, HE−Se interacts with polysulfides to promote their conversion, effectively mitigating the shuttle effect. On the other hand, HE−Se provides multiple lithophilic sites during the initial nucleation of Li+, which reduces overpotential and exhibits excellent lithophilicity and cyclic stability. As a result, Li−S batteries incorporating the HE−Se hosts demonstrate outstanding performance in terms of rate capability and cycling stability. Additionally, the porous lithophilic HE−Se structure offers sufficient nucleation sites, inhibits the growth of dendritic lithium, and accommodates volume changes during charging and discharging cycles. This study highlights the potential of sulphophilic/lithophilic high‐entropy materials in designing advanced Li−S batteries and encourages further exploration in this area.
Accuracy of daily extreme air temperatures under natural variations in thermometer screen ventilation
Authors: Harrison R. Giles , Burt Stephen D. 
Published: August 2024

AbstractAccurate air temperatures underpin environmental research. Most professional meteorological air temperature measurements still expose thermometers within traditional, naturally ventilated screens. Their representation of true air temperature depends on screen airflow, and therefore local winds. Accuracies of daily maximum (Tmax) and minimum (Tmin) air temperatures are assessed by comparison between a naturally ventilated large conventional screen and a co‐located aspirated reference screen. In over 1200 days' data, the naturally ventilated Tmin and Tmax both showed small (median < 0.06°C) cold bias, but, in 1% of cases, warm Tmax bias and cold Tmin bias >|1°C|. The Tmin cold bias is associated with calm clear nights, and the Tmax warm bias events with calm winter days at low sun angles, allowing solar heating of the screen. The prevalence of poor natural ventilation, potentially affecting Tmin and Tmax, is estimated across European sites. Poor ventilation occurred at Tmin for 12% of values, and at Tmax for 4%. Climatological averaging will reduce these effects, but, without corroborating wind data, statistical changes in Tmin or Tmax, including identifying “Tropical Nights” (Tmin > 20°C) or occurrences of winter extremes, may have limited value. Wider adoption of aspirated thermometer screens, with an initial overlap period, will largely eliminate these effects.

AbstractOwing to their excellent photoelectric properties, donor‐acceptor (D−A) type photocatalytic covalent organic frameworks (COFs) have attracted significant research interest in recent years. However, the limited D−A structural units of existing COFs restrict the development of novel and efficient photocatalytic COF materials. To solve this problem, we developed a series of D−A‐A‐type COFs utilizing a Lewis acid regulation strategy, in which Lewis acids act as the coordination centers, and pyridine and cyano groups act as ligands. Lewis acid sites in COFs serve as electron acceptors, facilitating the separation and transfer of photogenerated electron‐hole pairs. This process is crucial for photocatalysis because it significantly increases the efficiency of the catalytic reaction by reducing the recombination rate of charge carriers. The developed Lewis acid‐activated D−A‐A COFs efficiently catalyzed the hydroxylation of various phenylboronic acid compounds under visible light. The developed catalysts are expected to contribute to increasing the fabrication efficiency of industrially important organic materials.

Published: August 2024

AbstractIn order to achieve an optimized design of a three‐coil wireless power transfer (WPT) system with constant voltage (CV) and constant current (CC) output characteristics, meeting the power supply demands of rechargeable loads for CV/CC, this paper conducts an in‐depth research on the three‐coil magnetically coupled resonance (MCR) WPT system. A novel method for CV/CC output switching under the MCR‐WPT system is proposed. Firstly, a coupled inductance model is established, and the compensation parameter expressions of both single‐transmitter single‐receiver (STSR) three‐coil WPT system with relay coil and double‐transmitter single‐receiver (DTSR) three‐coil WPT system are derived. A compensation network parameter design method to achieve zero phase angle (ZPA) condition is proposed. This proposed three‐coil WPT system can achieve CV/CC output switching by a single alternating current (AC) switch. The transmission characteristics of these two MCR‐WPT systems are analyzed, and the transmission efficiency and lateral offset capability of the systems are compared. Experimental results demonstrate stable energy transfer of the system, validating the correctness and effectiveness of the proposed system's CV/CC output characteristics and parameter design methods. The results indicate that the proposed system can achieve stable CV/CC output.

AbstractWe prepared numerous thiazole derivatives from push‐pull alkenes such as nitroenamines, enaminoester, and enaminonitrils in a two‐step reaction with thiocyanate ion. The first step was the formation of the thiocyanate‐substituted push‐pull alkene from an iodine‐containing intermediary. We demonstrated this sequence through the preparation and identification of the iodine‐substituted enamines. In the second step, thiazole ring closure took place in methanol, at room temperature. The imino group of the condensed thiazole ring systems was successfully acylated. The same reaction sequence with potassium selenocyanate resulted in two selenocyanate and a selenazole heterocyclic derivatives. The mechanism of the reaction with thiocyanate ion and the heterocycle formation was investigated by computational methods. We performed quantum chemical calculations, involving both the thermodynamic and the kinetic aspects of the ring closure reaction.

AbstractThe arrangement of solvent molecules and ions at solid–liquid interfaces determines electrochemical properties that are important in separations platforms, sensing technologies, and energy‐storage systems. Here we show that single glass and polymer pores in contact with propylene carbonate (PC) solutions of LiClO4 exhibit an effective surface potential that is modulated by the enantiomeric excess of the solvent. In particular, electrochemical and electrokinetic measurements of ionic transport through glass pipettes and polymer pores reveal that the effective surface potential is significantly lower in solutions prepared using enantiomerically pure PC than in solutions prepared using racemic PC. Both pore systems became positively charged in all racemic solutions examined in the range of LiClO4 concentrations between 1 mM and 100 mM, whereas solutions in (R)‐(+)‐PC induced a positive surface potential only at concentrations above ~5 mM. The effective surface potential is quantified through asymmetry in current–voltage curves and zeta‐potential measurements. Vibrational sum‐frequency‐generation experiments on LiClO4 solutions in racemic and enantiomerically pure PC indicate that the surface lipid‐bilayer‐like region in the former is more strongly organized than in the latter, dictating the favorable positions for lithium and perchlorate ions in each case. The more ordered molecular packing in the racemic liquid leads to accumulation of lithium ions on the outside of the bilayer, creating a higher effective positive charge. Our results highlight the extreme sensitivity of the interfacial potential on molecular organization of the solvent, and the relatively unexplored role that chirality can play in electrokinetic phenomena.
Forecasting Markov switching vector autoregressions: Evidence from simulation and application
Authors: Cavicchioli Maddalena 
Published: August 2024

AbstractWe derive the optimal forecasts for multivariate autoregressive time series processes subject to Markov switching in regime. Optimality means that the trace of the mean square forecast error matrix is minimized by using suitable weighting observations. Then we provide neat analytic expressions for the optimal weights in terms of the matrices involved in a state space representation of the considered process. Our matrix expressions in closed form improve computational performance since they are readily programmable. Numerical simulations and an empirical application illustrate the feasibility of the proposed approach. We provide evidence that the forecasts using optimal weights increase forecast precision and are more accurate than the traditional Markov switching alternatives.

Published: August 2024

AbstractCotton, cotton yarn, and other cotton products have frequent price volatility, increasing the difficulty for industry participants to develop rational business decision plans. To support cotton textile industry decision‐makers, we apply data mining methods to extract the main influencing factors affecting cotton yarn futures prices from big data and build a probabilistic forecasting model for cotton yarn price volatility with uncertainty assessment. Based on Explainable Artificial Intelligence (XAI) and data‐driven perspectives, we use the LassoNet algorithm to extract 18 features most relevant to the target variable from the massive data and visualize the importance values of the selected features to improve the reliability. Moreover, by combining conformal forecasting (CP) with quantile regression (QR), the uncertainty measure of the point estimation results of the long and short‐term memory (LSTM) model is applied to improve the application value of the model. Finally, SHAP (SHapley Additive exPlanations) is introduced to analyze the SHAP values of the input features on the output results and to explore in depth the interaction and mechanism of action between the input features and the target variables to improve the explainability of the model. Our model provides a “big data‐forecasting model‐decision support” decision paradigm for real‐world problems.
