Published: December 2021

AbstractZn‐salt poly(styrene–ran–cinnamic acid) (SCA–Zn) ionomers were successfully synthesized via the melt neutralization of poly(styrene–ran–cinnamic acid) (SCA), which has a comparable molecular weight ( = 217,000) to commercial polystyrene (PS), with different mass fractions of ZnO (0.62, 1.6, and 3.9 wt.%) and the successful synthesis was confirmed by Fourier transform infrared spectroscopy. The mechanical properties, heat resistance, and processibility of the PS, SCA, and SCA–Zn samples were characterized. Compared to SCA, the three SCA–Zn ionomers exhibited significantly higher αcN values, with the ionomers containing 1.6 and 3.9 wt.% ZnO were 11.4% and 68.6% higher than that of SCA, respectively. Compared to commercial PS, SCA–Zn also exhibited significant improvements in heat resistance (glass transition temperature and vicat softening temperature both improved by about 20 °C) and impact toughness (αcN values of the ionomers containing 1.6 and 3.9 wt.% ZnO were 69.6% and 156.5% higher than that of PS), while the processability of SCA–Zn was not significantly worse than that of PS. This method efficiently improves both the toughness and heat resistance of PS, providing an efficient way to expand the market application of styrenic resins.
Bio‐based and hydrolytically degradable hydroxyurethane acrylates as photocurable thermosets
Authors: Younes Georges R. , Maric Milan 
Published: December 2021

AbstractThis study focuses on the synthesis of bio‐based and hydrolytically degradable photocurable thermosets made from hydroxyurethane acrylates (HUA). The hydroxyurethanes (HUs) are prepared from the reaction between ethylene carbonate and a bio‐based diamine, Priamine 1074. Subsequently, the HU initiates the ring opening polymerization of ε‐caprolactone (CL), resulting in telechelic groups of 5 CL units at both ends of the HU. The resulting HU‐CL5 is finally acrylated to prepare the degradable HUA (HU‐CL5‐A) with transformations confirmed following each step via proton nuclear magnetic resonance (1H‐NMR) and Fourier‐transform infrared (FTIR) spectroscopies. HU‐CL5‐A is photocured with 4‐acryloylmorpholine (ACMO) as a photosensitive reactive diluent. The photocurable thermosets exhibit slight water swelling (swelling index of 46%), as Priamine 1074 and ACMO are hydrophobic and hydrophilic, respectively, leading to the slow and partial degradation of the films in water at 85°C for 14 days. The cleavage of the CL units from the film networks is proven via 1H‐NMR and FTIR, which demonstrates the main objective of this study in synthesizing photocurable and degradable HUA resins.
VLBA observations of extremely luminous, young, and highly obscured radio quasars from the WISE‐Radio sample

Published: December 2021

AbstractA snapshot imaging survey with the VLBA at 5 GHz of 90 of the reddest, most obscured quasars with Ultra Luminous InfraRed Galaxy‐level infrared luminosities reveals a range of small jet structures and also unresolved sources. The three highest frequency peakers in the sample show little evidence for any substantial radio emission on scales larger than about 100 pc, based on our VLA data and on archival survey data. These may be very young single‐epoch radio quasar events. Sources with lower peak frequencies, in the gigahertz peaked source (GPSs), tend to have VLBA fluxes that under‐predict the larger scale emission, indicating multiple structures and possibly multiple epochs of jet activity. One GPS source shows evidence for strong absorption at low frequencies, consistent with this hypothesis. Multifrequency and multiresolution imaging of a subset of 12 of the sample with VLA, VLBA, and eMerlin are under analysis.

Published: December 2021

AbstractDie neue Generation von Befestigungssystemen der Installationstechnik ist gekennzeichnet durch eine frühzeitige Einbindung in die Planungsphase, einen hohen Vorfertigungsgrad, effiziente Montagezeiten, deutliche Materialersparnisse sowie eine optimale Raumnutzung unter Einhaltung aller relevanten Vorschriften. Die Ausnutzung dieser Optimierungspotenziale wird erst ermöglicht durch eine frühzeitige und gewerkübergreifende Befestigungsplanung für die technische Gebäudeausrüstung, bei der gemeinsame Tragstrukturen für Leitungen aller betroffenen Ausbaugewerke konzipiert werden. Dabei müssen auch für das Gesamtsystem div. Auflagen in Bezug auf den Brandschutz erfüllt werden. Mit der Bereitstellung technischer Regelwerke für die Auslegung von modularen Tragsystemen unter Brandbedingungen werden entsprechende Bemessungskonzepte vermehrt in der Praxis eingesetzt. Dieser Beitrag gibt eine allgemeine Einführung in die Konzeption modularer Tragsysteme und deren Auslegung im Brandfall und beschreibt anhand eines Projektbeispiels, wie auch anspruchsvolle Planungsanforderungen in Bezug auf den Brandschutz effizient umgesetzt werden können. Das gewählte Projektbeispiel – das Kantonsspital Baden in der Schweiz – steht dabei exemplarisch für ein Großprojekt im Gesundheitswesen mit herausfordernden Anforderungen an den Brandschutz für Tragsysteme der technischen Gebäudeausrüstung.

AbstractBackgroundThe present study investigated the joint impact of adolescent sport experience and dopamine‐related genes (i.e., DRD2 and COMT genes) on sport participation in adulthood.MethodsUsing the National Longitudinal Study of Adolescent Health (Add Health) data, the hierarchical multivariable logistic regression models for predicting sport participation in wave 3 (around 20 years of age) and wave 4 (around 30 years of age) were conducted separately by gender (male and female) and gene (DRD2 and COMT genes).ResultsAdolescent sport experience significantly interacted with the number of DRD2 A1 alleles and COMT Met alleles in affecting wave 3 sport participation among male adults. The interaction between adolescent sport experience and DRD2 gene significantly affected wave 4 sport participation in opposite direction to that affected wave 3 sport participation among male participants. Among female participants, there were no significant interaction effects between dopamine‐related genes and adolescent sport experience on sport participation in both wave 3 and 4.ConclusionsSince adult sport participation is most likely to be influenced by the joint impact of environmental and genetic factors, it is important to consider gene‐by‐environment interactions when designing policies or programs to promote adult sport participation.

AbstractBackgroundTo determine the association of 30‐day readmission with weekend discharge and the number of holiday days during a hospital stay (holiday ratio).MethodsThis retrospective cohort study used the clinical research database and cancer registry data of our hospital from January 1, 2011 to December 31, 2017. Patient characteristics, tumor factors, clinical laboratory data, and proxies of continuity of care, such as weekend discharge or holiday ratio (holiday days/total hospitalization days), received statistical analysis. Multivariate logistic regression identified the independent factors for 30‐day potentially avoidable readmission rate (PAR).ResultsOf 1433 patients receiving tumor resection, 520 (36.29%) had colon cancer; 440 (30.70%) had head and neck cancer (HNC), and 473 (33.01%) had other cancers (lung, liver, and prostate). The rate of 30‐day PAR was 6.3% for those with colon cancer, 8.6% for HNC, and 3.6% for other cancers. The 30‐day PAR did not significantly differ by discharge on a weekend versus weekday for those with colon cancer (8.33% vs. 5.90%; p = 0.379), HNC (7.06% vs. 9.01%; p = 0.566), or other cancers (0.00% vs. 4.28%; p = 0.960). Colon cancer patients with holiday ratio >0.3 had a higher readmission rate (9.58% vs. 4.82%, p = 0.041). In multivariate analysis, a holiday ratio >0.3 (adjusted odds ratio 2.16; 95% Confidence Interval, 1.05–4.39) in those with colon cancer was an independent predictor of 30‐day PAR.ConclusionsWeekend discharge after major surgery did not affect 30‐day readmission rates in cancer patients, but the holiday ratio did affect 30‐day PAR for those with colon cancer.
Asymmetrically Substituted m‐Terphenyl Phosphates Inhibit the Transcription Factor STAT5a
Authors: Müller‐Klieser Daniel , Berg Thorsten 
Published: December 2021

AbstractWe recently presented Stafia‐1 as the first chemical entity that inhibits the transcription factor STAT5a with selectivity over the highly homologous STAT5b. Stafia‐1, which was identified from a series of symmetrically substituted m‐terphenyl phosphates, binds to the interface between the SH2 domain and the linker domain of STAT5a. Here, we outline a synthetic strategy for the synthesis of asymmetrically substituted m‐terphenyl phosphates, which can be tailored to address their asymmetric STAT5a binding site in a more specific manner. The asymmetrically substituted m‐terphenyl phosphate with the highest activity against STAT5a was converted to a phosphatase‐stable monofluoromethylene phosphonate. The synthetic methodology and activity analysis described here provide first insights into the structure‐activity relationships of m‐terphenyl phosphates for use as selective STAT5a inhibitors.
A Simple Method to Design a Decoupler for a Proton Exchange Membrane Fuel Cell

Published: December 2021

AbstractA decoupling control system is designed by a simple tuning‐free method for the multi‐input multi‐output model of a proton exchange membrane fuel cell. The decoupler minimizes the interactions among the loops and is designed by estimating the relative normalized gain array and dynamic relative gain array for the closed‐loop model. The proportional integral controller settings are estimated using the partial model matching method. The performances of the proposed method are studied based on closed‐loop performances of control variables and time integral errors that are compared with the synthesis method. The proposed controller performs better in terms of integral of time‐weighted absolute error.

AbstractDry reforming of methane (DRM) is an important way to produce synthesis gas, requiring the use of catalysts stable at high temperatures and capable of resisting coke formation. In this work, Ni/Al2O3 and Ni/Mg‐Al2O3 catalysts were synthesized with calcined aluminas at different temperatures (623, 773, 923, and 1073 K) to evaluate the effect of calcination temperature on catalyst properties and performance. The synthesis of catalysts was performed by wet impregnation with predicted levels of Ni (10% w/w) and Mg (5% w/w) in the treated supports. The DRM assays were conducted in an experimental laboratory unit (continuous fixed bed reactor with in‐situ catalyst activation) using a 1:1 (v/v) CH4:CO2 mixture, a weight basis gas hourly space velocity (WGHSV) of 15 L h−1 gcat−1, and operation at 973 K. The reaction product was evaluated by gas chromatography. Variations in CH4 and CO2 conversions and H2/CO ratio were observed, indicating that these catalysts have different physical and chemical characteristics attributed to different effects caused by calcinating the supports (Al2O3 and Mg‐Al2O3) at different temperatures.

BackgroundEndoscopic ultrasound–guided tissue acquisition (EUS‐TA), especially endoscopic ultrasound–guided fine‐needle aspiration (EUS‐FNA), is the mainstay of tissue acquisition for the diagnosis of pancreatic ductal adenocarcinoma (PDAC). Recently, endoscopic ultrasound–guided fine‐needle biopsy (EUS‐FNB) using flexible biopsy needles has been used for patients with PDAC in an effort to increase diagnostic yields and biomarker testing. However, the role of EUS‐TA in biomarker testing for personalized therapy or precise chemotherapy for PDAC is not well established.MethodsPDAC cases with specimens acquired through concurrent EUS‐FNA and EUS‐FNB were identified retrospectively. Smears were prepared from EUS‐FNA sampling, and cell blocks (CBs) were prepared from EUS‐FNB sampling. Rapid onsite evaluation was conducted for all cases for diagnostic adequacy. The adequacy for biomarker testing, including next‐generation sequencing (NGS) and immunohistochemistry (IHC) assays, was evaluated, and cases with smears and CBs adequate for NGS were processed for targeted NGS.ResultsThere were 26 PDAC cases concurrently sampled by EUS‐FNA and EUS‐FNB. EUS‐FNA smears for all 26 cases and EUS‐FNB CBs for 20 cases (77%) were diagnostic for PDAC. Twenty‐one smears (81%) and 11 CBs (42%) were adequate for NGS. Nine cases with both smears and CBs adequate for NGS underwent NGS, which identified clinically significant gene mutation variants, including KRAS, TP53, and SMAD4 mutations.ConclusionsBoth EUS‐FNA and EUS‐FNB can provide optimal material for targeted NGS for PDACs. In PDAC cases subjected to concurrent EUS‐FNA and EUS‐FNB, EUS‐FNA specimens had greater diagnostic yields and more adequate material for NGS than EUS‐FNB specimens, whereas EUS‐FNB was more suitable for IHC‐based biomarker testing.

AbstractThe computational tool known as Power Flow is essential for planning and operating electrical networks, especially considering the interconnected ones, which leads to tackle more complex, large‐size modeling problems and perform extensive analyses during decision‐making processes. This paper proposes a practical approach to solve the power flow problem using parallel computation of the Newton–Raphson method. To this aim, CPU and GPU implementations are tested and a hybrid CPU‐GPU approach proved to be more effective to solve the problem in hand. Numerical results obtained on benchmark power networks are presented and discussed.

AbstractSingle organic molecules are promising photon sources for quantum technologies. In this work we show photon emission from dibenzoterrylene, a widely used organic emitter, in a new host matrix,para‐terphenyl. We present a reprecipitation growth method that producespara‐terphenyl nanocrystals which are ideal for integration into nanophotonic devices due to their small size. We characterise the optical properties of dibenzoterrylene in nanocrystals at room and cryogenic temperatures, showing bright, narrow emission from a single molecule. Spectral data on the vibrational energies is presented and a further 25 additional molecules are characterised. This emitter‐host combination has potential for quantum technology purposes with wavelengths suitable for interfacing with quantum memories.

AbstractOrdered mesoporous CuNiCo oxides were prepared via nanocasting with varied Cu/Ni ratio to establish its impact on the electrochemical performance of the catalysts. Physicochemical properties were determined along with the electrocatalytic activities toward oxygen evolution/reduction reactions (OER/ORR). Combining Cu, Ni, and Co allowed creating active and stable bifunctional electrocatalysts. CuNiCo oxide (Cu/Ni≈1 : 4) exhibited the highest current density of 411 mA cm−2 at 1.7 V vs. reversible hydrogen electrode (RHE) and required the lowest overpotential of 312 mV to reach 10 mA cm−2 in 1 m KOH after 200 cyclic voltammograms. OER measurements were also conducted in the purified 1 m KOH, where CuNiCo oxide (Cu/Ni≈1 : 4) also outperformed NiCo oxide and showed excellent chemical and catalytic stability. For ORR, Cu/Ni incorporation provided higher current density, better kinetics, and facilitated the 4e− pathway of the oxygen reduction reaction. The tests in Li−O2 cells highlighted that CuNiCo oxide can effectively promote ORR and OER at a lower overpotential.
Cytologic presentation of ovarian large cell carcinoma with rhabdoid features detected on peritoneal washing. Report of one case with cyto‐histologic correlation and previously undescribed inactivating SMARCA‐4 mutations

Published: December 2021

AbstractThe SMARCA subgroup of genes belongs to the SWI1/SNF1 family, responsible for chromatin remodeling and repair within the nucleosome. The SMARCA4 gene is located on chromosome 19p13 and encodes the BRG1 (BRAhMA) protein. We report the cytological and histological findings in one case of large cell SMARCA4 deficient ovarian carcinoma with positive peritoneal washing in a 69‐year‐old woman. The neoplastic cells were present as singly lying or perivascular clusters and showed medium or large size, round to oval hyperchromatic nuclei, and scarce to moderate cytoplasms. Molecular pathology investigations performed on the ovarian surgical sample found two previously undescribed mutations in the SMARCA4 gene and additional mutations in the CTNNB1 (Beta Catenin gene) and in PIK3CA. To our knowledge, this case probably represents the third cytologic report of this variant of ovarian carcinoma and the first one with molecular pathologic study.

AbstractObjectiveFindings show virtual therapy (conducted using internet‐based videoconferencing techniques) to be a viable alternative to in‐person therapy for a variety of mental‐health problems. COVID‐19 social‐distancing imperatives required us to substitute virtual interventions for in‐person sessions routinely offered in our outpatient eating disorder (ED) program—and afforded us an opportunity to compare the two treatment formats for clinical efficacy.MethodsUsing self‐report assessments, we compared outcomes in a historical sample of 49 adults with heterogeneous EDs (treated in‐person over 10–14 weeks in individual and group therapies) to those of 76 patients receiving comparable virtual treatments, at distance, during the COVID‐19 outbreak. Linear mixed models were used to study symptom changes over time and to test for differential effects of treatment modality.ResultsParticipants in both groups showed similar improvements on eating symptoms, levels of weight gain (in individuals in whom gain was indicated), and satisfaction with services.DiscussionOur results suggest that short‐term clinical outcomes with virtual and in‐person ED therapies are comparable, and point to potentials of virtual therapy for situations in which geographical distance or other barriers impede physical access to trained therapists or specialized treatments.
