AANEM survey of training in electrodiagnostic medicine in U.S. residency programs
Authors: Donofrio Peter D. , Govindarajan Raghav 
Published: March 2020

AbstractBackgroundLittle literature exists describing resident training in peripheral electrodiagnosis (EDX).MethodsU.S. residency programs in neurology and physical medicine and rehabilitation (PM&R) were surveyed by the AANEM (American Association of Neuromuscular and Electrodiagnostic Medicine) on specific features of EDX training.ResultsNinety‐seven programs responded to the survey. Training duration was 4–8 weeks in most neurology programs; training averaged 22 weeks in PM&R programs. EDX experience was required in all PM&R and in 90% of neurology programs. Results varied greatly for the residency years of training, pulling of residents for other responsibilities, participation in continuity clinics, number of teaching physicians, number of needle examinations performed, organization of nerve conduction training, written/oral examinations, muscle/nerve biopsy reviews, and training materials.ConclusionsThis survey demonstrated large variability in training of neurology and PM&R residents in peripheral EDX.

AbstractIntroductionSmall‐fiber neuropathy is rare in children. It has been associated with several autoimmune disorders, but there are no reports of an autoinflammatory etiology.MethodsThe data of four children/adolescents presenting with erythromelalgia and neuropathic pain from 2014 to 2019 were collected retrospectively from the electronic database of a pediatric medical center.ResultsResults of clinical and/or electrophysiological evaluation excluded large nerve fiber involvement. Skin biopsy results confirmed small‐fiber neuropathy. According to genetic analysis, two patients were heterozygous and one was homozygous for mutations in the familial Mediterranean fever (MEFV) gene. Behcet disease was diagnosed in the fourth patient. Treatment with anti–interleukin‐1 agents, intravenous immunoglobulin, and glucocorticoids was beneficial.DiscussionThe diagnosis of small‐fiber neuropathy should be considered in children/adolescents presenting with erythromelalgia. A thorough investigation is required to reveal the underlying disorder. Clinicians should be alert to the peripheral neurological manifestations of autoinflammatory syndromes because effective treatments are available.

AbstractIntroductionResearch has shown that quality of health‐care services is often suboptimal. Little is known about the quality of electrodiagnostic testing.MethodsWe prospectively recruited 477 adults with workers' compensation claims for carpal tunnel syndrome (CTS) from 30 occupational health clinics and evaluated whether electrodiagnostic testing adhered to five process‐oriented quality measures.ResultsAmong patients who had surgery for CTS, nearly all underwent recommended preoperative electrodiagnostic testing (measure #1, 170 of 174, 97.7%). Most electrodiagnostic tests included essential components (measure #2, 295 of 379, 77.8%). However, few reports documented skin temperature (measure #3, 93 of 379, 24.5%) and criteria were seldom met for interpreting test findings as consistent with CTS (measure #4, 41 of 284, 14.4%) or “severe” CTS (measure #5, 8 of 46, 17.4%).DiscussionMost patients underwent testing before surgery, but test quality was often suboptimal. This work lays the groundwork for future efforts to monitor and improve the quality of electrodiagnostic testing for CTS.
Purchase and retrieval competition for seasonal produce

Published: March 2020

AbstractWe study the competition problem of purchase and multiretrieval of perishable seasonal produce, where wholesalers purchase and stock their products in the first period, and then retrieve and sell them in subsequent periods. We first consider the duopoly case and assume that the prices are exogenous and fluctuate. In each period, after the price realization, the wholesalers retrieve some stock from their warehouses to satisfy their demands. One wholesaler's unsatisfied customers can switch to another and be satisfied by its left retrieved products. Any unsold retrieved stock has no salvage value and any unsatisfied demand is lost. The unretrieved stock is carried to the next period at a perishable rate. The wholesalers compete for the substitute demand by determining their own purchase and retrieval quantities. We show the existence and uniqueness of a pure‐strategy Nash equilibrium, and that the Nash equilibrium strategy has the simple “sell‐down‐to” structure. We also consider the general N‐person game and show the existence of the Nash equilibrium, and characterize the structure of the equilibrium strategy for the symmetric case. In addition, we consider the case with endogenous prices, and show that the problem reduces to a repeated newsvendor game with price and inventory competition. We derive the conditions under which a unique Nash equilibrium exists and characterize the equilibrium strategy. Finally, we conduct numerical studies to examine the impacts of the model parameters on the equilibrium outcomes and to generate managerial insights.

AbstractShape memory polymer nanocomposites based on thermoplastic polyurethane (TPU)/polylactic acid (PLA) blends filled with pristine multi‐walled carbon nanotubes (MWCNTs) and modified MWCNTs─COOH were fabricated by direct melt blending technique and investigated for its morphology, mechanical, thermal, electrical, and shape memory properties. Morphological characterizations by using transmission electron microscope (TEM) and field emission scanning electron microscope (FESEM) revealed better dispersion of MWCNTs─COOH in the polymer blend, which is attributed to the improved interfacial interactions between the polymer blends and MWCNTs‐COOH. Loading of the MWCNTs‐COOH in the TPU/PLA blends resulted in the significant improvements in the mechanical properties such as tensile strength and elastic modulus and these effects are more pronounced on increasing the MWCNTs─COOH loading amount, when compared to the pristine MWCNTs filled system. Thermal analysis showed that the glass transition temperature of the blends increases slightly with increasing loading of both pristine and modified MWCNTs in the system. The resistance of nanocomposites decreased from 2 × 1012 Ω to 3.2 × 1010 Ω after adding 3% MWCNTs─COOH. The shape memory performance tests showed that the enhancement of shape recovery by 252% could be achieved at 3% MWCNTs loading, when compared to that of TPU/PLA blends.
“They can even make waiting in line fun”: A quantitative content analysis of autistic children's friendship conceptualizations
Authors: Malloy Caitlin , Cuda Josephine , Kim So Yoon , Bottema‐Beutel Kristen 
Published: March 2020

AbstractWe explored third‐ to fifth‐grade children's friendship concepts in 20 autistic and 21 nonautistic students matched for mental age. Transcripts of semi‐structured interviews were coded for definitions of friendship, friendship expectations, and friendship transgressions (i. e., violations of friendship expectations), and subjected to quantitative content analysis. Findings demonstrated that children's definitions of friendship were largely aligned with their views on friendship expectations and transgressions. Kindness was significantly less salient to autistic children's definitions of friendship than for their nonautistic peers; otherwise, the two groups showed conceptualizations of friendship that were quite similar. Findings have implications for practitioners and researchers seeking to support autistic children's friendship experiences and bring to light important considerations for researchers seeking to better understand autistic friendship experiences.
Mesomorphic properties of linear and branched new triphenylene‐based poly(ester‐ether)s
Authors: Suburu Matias E. G. , Cecchi Florencia , D'Accorso Norma , Cukiernik Fabio Daniel 
Published: March 2020

AbstractA series of main chain discotic liquid crystal polymers, synthesized following a new approach based on the incorporation of triphenylene units in both comonomers, show ordered columnar mesophases in a very wide thermal range, including room temperature. The introduction of branching points based on the same kind of triphenylene units increases their thermal range and gives rise to glassy low‐temperature phases. Room temperature extrusion of these polymers yields fibers with molecules oriented perpendicular to the mechanical stress, and an orientational order parameter close to 0.5, which slightly increases for branched polymers.

AbstractPurposeTo discuss the different characteristics of clinical, laboratory, and chest computed tomography (CT) in pediatric patients from adults with 2019 novel coronavirus (COVID‐19) infection.MethodsThe clinical, laboratory, and chest CT features of 20 pediatric inpatients with COVID‐19 infection confirmed by pharyngeal swab COVID‐19 nucleic acid test were retrospectively analyzed during 23 January and 8 February 2020. The clinical and laboratory information was obtained from inpatient records. All the patients were undergone chest CT in our hospital.ResultsThirteen pediatric patients (13/20, 65%) had an identified history of close contact with COVID‐19 diagnosed family members. Fever (12/20, 60%) and cough (13/20, 65%) were the most common symptoms. For laboratory findings, procalcitonin elevation (16/20, 80%) should be pay attention to, which is not common in adults. Coinfection (8/20, 40%) is common in pediatric patients. A total of 6 patients presented with unilateral pulmonary lesions (6/20, 30%), 10 with bilateral pulmonary lesions (10/20, 50%), and 4 cases showed no abnormality on chest CT (4/20, 20%). Consolidation with surrounding halo sign was observed in 10 patients (10/20, 50%), ground‐glass opacities were observed in 12 patients (12/20, 60%), fine mesh shadow was observed in 4 patients (4/20, 20%), and tiny nodules were observed in 3 patients (3/20, 15%).ConclusionProcalcitonin elevation and consolidation with surrounding halo signs were common in pediatric patients which were different from adults. It is suggested that underlying coinfection may be more common in pediatrics, and the consolidation with surrounding halo sign which is considered as a typical sign in pediatric patients.
Study of TATP: Impact of TATP Sublimation on the Content of Residual Acid in TATP Crystals and on TATP's Properties
Authors: Matyáš Robert , Chýlková Jaromíra 
Published: March 2020

AbstractThe impact of four inorganic acids (hydrochloric, sulfuric, nitric and perchloric) and six organic acids (formic, acetic, citric, tartaric, oxalic and ascorbic) on the acid concentration in raw TATP crystals and the behavior of TATP during heating have been studied. The residual acid content in solid TATP depends on the type of acid and on its concentration in the reaction mixture. Increasing the concentration of acid in the reaction mixture leads to a higher acid content in TATP crystals. Sublimation of TATP during storage also has a significant impact on the acid concentration in TATP crystals. Sublimation of TATP gradually increases the content of non‐volatile acid in TATP crystals (sulfuric and solid organic acids) while the content of volatile acids (hydrochloric, nitric) does not significantly change during TATP sublimation. The increasing sulfuric acid content in TATP crystals during sublimation decreases thermal stability of TATP and the start of TATP decomposition was observed even at 45 °C. The concentration of volatile hydrochloric and nitric acids does not change significantly in TATP crystals during sublimation and, therefore, the sublimation process does not have an impact on TATP's thermal stability in these cases.

Published: March 2020

AbstractAfter the emergency occurred, emergency supplies are an important guarantee for the emergency response activities in chemical park. Rapid procurement and rational transfer of emergency supplies are the key to improve the efficiency of emergency response. Based on the construction needs and development trends of the “smart park” concept, an integrated process of emergency supplies management is proposed in this article. It covers all aspects of emergency supply, such as procurement, storage, inspection, maintenance, and transshipment. Meanwhile, taking Shanghai Chemical Industry Park (SCIP) as a case, an Emergency Supply Reserve Management System (ESRMS) is puts forward according to the current management model of the park. In order to realize dynamic management, maintenance, procurement, transshipment, and other functions the software platform is developed. According to the research results, the role of supplies in emergency response activities was systematically expounded, which strengthened the central position of Emergency Response Center (ERC) of chemical park. It can provide some reference for the management of similar chemical parks.

AbstractBACKGROUNDThe use of spinosyn insecticides is one of the major control strategies of the fall armyworm, Spodoptera frugiperda (J. E. Smith) in Brazil. In this study, we selected a spinetoram‐resistant strain from a field‐population of S. frugiperda to characterize the inheritance of the resistance and cross‐resistance relationship between spinosyn insecticides.RESULTSThe values of LC50 (95% CI) obtained from concentration–response bioassays were 0.63 (0.55–0.73) μg spinetoram mL−1 for the susceptible strain (SUS), and 1170.96 (1041.61–1323.89) μg spinetoram mL−1 for the strain resistant to spinetoram (SPT‐R). These values resulted in a resistance ratio of 1844‐fold. The SPT‐R strain showed cross‐resistance with spinosad (resistance ratio = 1196‐fold). The reciprocal crosses showed LC50 values of 3.91 (2.97–5.84) and 5.37 (4.52–6.52) μg spinetoram mL−1, suggesting that the resistance of S. frugiperda to spinetoram is autosomal and incompletely recessive. The backcrosses of the F1 progeny with the SPT‐R strain suggest a resistance with polygenic effect. Estimates of the effective number of loci with equal contributions to the resistance effect were from 1.18 to 1.76, suggesting that resistance to spinetoram is associated with a few genes.CONCLUSIONThe inheritance pattern of resistance of S. frugiperda to spinetoram was characterized as autosomal, incompletely recessive and polygenic. Cross‐resistance between spinosyns was confirmed in S. frugiperda. The importance of this information for implementing insect resistance management strategies is discussed in this paper. © 2020 Society of Chemical Industry
Virial relations in density embedding

Published: March 2020

AbstractThe accuracy of charge‐transfer excitation energies, solvatochromic shifts, and other environmental effects calculated via various density‐embedding techniques depend critically on the approximations employed for the nonadditive noninteracting kinetic energy functional, . Approximating this functional remains an important challenge in electronic‐structure theory. To assist in the development and testing of approximations for , we derive two virial relations for fragments in molecules. These establish separate connections between the nonadditive kinetic energies of the noninteracting and interacting systems of electrons, and quantities such as the electron‐nuclear attraction forces, the partition (or embedding) energy and potential, and the Kohn‐Sham potentials of the system and its parts. We numerically verify both relations on diatomic molecules.

Published: March 2020

AbstractPrimary pleural synovial sarcoma (PPSS) is an extremely rare malignancy without a known cause. The diagnosis is made after excluding metastasis from an extra‐thoracic sarcoma. We report a case of a 67‐year‐old gentleman who presented with an incidental finding of a left lung mass on a routine chest X‐ray. A computed tomography (CT) of the thorax and whole‐body positron emission tomography (PET)‐CT was done confirming a left lung mass with no other extra‐thoracic involvement. A lobectomy was performed with a diagnostic and therapeutic intent. The histopathological examination and immunohistochemistry study revealed a pleural‐based tumour with features suggestive of synovial sarcoma. Subsequently, he underwent post‐operative radiotherapy. However, three months later, he developed an endobronchial recurrence, complicated by post‐obstructive pneumonia resulting in his demise. This case highlights a rare form of malignancy with a rare site of recurrence.
Status monitoring of ion sputter relevant parameters of an XPS depth profiling instrument
Authors: Scheithauer Uwe 
Published: March 2020

An X‐ray photoelectron spectroscopy (XPS) instrument is utilized for sputter depth profiling of thin films. Relevant instrumental parameters are the ion gun sputter rate, the contamination level of the sputter ion gun, and the purity of the sputter ion gun gas supply as well as the vacuum quality of the instrument at the sample position. A long‐term recording of these instrumental parameters ensures the reliability of the measured depth profile data.The ion gun sputter rate was estimated using the standard ISO conform depth profiling of a SiO2 reference layer of known thickness. Two new procedures are developed to determine the other relevant parameters. Gases that are emitted by the ion sputter gun get implanted into a Si target. An analysis of the implanted gases allows judging on the contamination level of the sputter gun and the purity of the sputter gun gas supply. The vacuum condition of an XPS microprobe at the sample position is monitored by the recontamination of a sputtered Ti surface by adsorbed residual gas particles.

Published: March 2020

AbstractUltrasound (US) assisted, catalyst and oxidant free, chemoselective protocol for the synthesis of diverse oxamates from oxalic acid and amines with alcohol is demonstrated efficiently. In situ formation of the corresponding esters from oxalic acid and alcohols reacts with amines and augments the formation of desired oxamates in remarkable yields under the employed reaction conditions. This protocol is amine‐selective, can tolerate other functional groups and also applicable for gram‐scale synthesis. When compared with conventional (NUS) method, the US method is found to be more superior in terms of reaction time and total energy consumption (84‐87% of energy is saved). The synthesized products are well characterized by 1H, 13C, and IR spectroscopic techniques.

Published: March 2020

AbstractAn efficient, clean and versatile strategy for the synthesis of 2,3,4‐triiodoanisole via one‐pot microwave‐assisted/Pd‐catalyzed domino C‐H iodination/ipso‐iododecarboxylation of 3‐anisic acid is presented. Significantly, the product is crystalline and bench stable solid which can be performed in good isolated yield. This report described a protocol for the first synthesis of hitherto unknown 2,3,4‐triiodoanisole that is catalytic, clean and scalable. Remarkably, the Suzuki‐Miyaura cross‐coupling reactions on the later compound were also demonstrated as a precursor providing 2,3‐diiodo‐4‐methoxybiphenyl and iodinated terphenyl derivatives in good yields and in excellent site‐selectivity.
Confined Bubble‐Propelled Microswimmers in Capillaries: Wall Effect, Fuel Deprivation, and Exhaust Product Excess

Published: March 2020

AbstractSelf‐propelled autonomous nano/microswimmers are at the forefront of materials science. These swimmers are expected to operate in highly confined environments, such as between the grains of soil or in the capillaries of the human organism. To date, little attention is paid to the problem that in such a confined environment the fuel powering catalytic nano/microswimmers can be exhausted quickly and the space can be polluted with the product of the catalytic reaction. In addition, the motion of the nano/microswimmers may be influenced by the confinement. These issues are addressed here, showing the influence of the size of the capillary and length of the micromotor on the motion and the influence of the depletion of the fuel and excess of the exhaust products. Theoretical modeling is provided as well to bring further insight into the observations. This article shows challenges that these systems face and stimulates research to overcome them.

Published: March 2020

AbstractDie Verwendung von vorgespannten Schraubverbindungen aus nichtrostendem Stahl ist in vielen Sonderfällen aus Gründen der Gebrauchstauglichkeit oder der Tragfähigkeit wünschenswert, z. B. beim Einsatz in besonders korrosiver Umgebung oder in Konstruktionen aus nichtrostendem Stahl. Die Verwendung von Schraubengarnituren aus nichtrostendem Stahl ist jedoch aus mehreren Gründen durch DIN EN 1090‐2 auf nicht vorgespannte Verbindungen beschränkt. Ressentiments bestehen nach wie vor gegenüber dem Einsatz in vorgespannten Verbindungen aufgrund befürchteter hoher Vorspannkraftverluste sowie der Problematik des Kaltverschweißens (Fressen). Darüber hinaus existieren am Markt derzeit keine Garnituren analog zur Normenreihe DIN EN 14399, welche seitens des Herstellers auf die Eignung zum Vorspannen geprüft werden und auch eine entsprechende kalibrierte Schmierung aufweisen. DIN EN 14399‐1 ist zudem auf den Einsatz von Schrauben aus Kohlenstoffstahl beschränkt, sodass auch hier normativ eine Verfahrensprüfung für den Einsatz durchzuführen ist. Der vorgestellte Beitrag soll einen Einblick in die Möglichkeiten der Verwendung von Schraubverbindungen aus nichtrostendem Stahl in vorgespannten Verbindungen im Allgemeinen und in gleitfesten Verbindungen im Speziellen geben. Ferner wird dem Anwender eine Hilfestellung und ein Leitfaden für das Vorgehen innerhalb einer Verfahrensprüfung durch die „Bolt Tightening Qualification Procedure“ (BTQP) als Ergänzung zu den Regelungen der DASt‐Richtlinie 024 gegeben.
