AbstractDeveloping efficient and stable Pt‐based oxygen reduction reaction (ORR) electrocatalysts via both economical and controllable routes is critical for the practical application of electrochemical energy devices. Herein, a scalable, controllable, and general ambient‐O2‐involved aqueous‐solution cultivating strategy to prepare PtxMy (M = Ni, Fe, Co) bunched‐nanocages aerogels (BNCs AG) is demonstrated, based on a newly established high‐M‐to‐Pt‐precursor‐ratio‐and‐B‐incorporation‐facilitated M‐rich core and Pt‐rich shell hydrogel formation process. The Pt83Ni17 BNCs AG shows prominent ORR performance with a mass activity (MA) of 1.95 A mgPt−1 and specific activity of 3.55 mA cm−2, which are 8.9‐times and 9.6‐times that of Pt supported on carbon (Pt/C), respectively. Particularly, the Pt83Ni17 BNCs AG displays greatly enhanced durability (MA 82.6% retention) compared to Pt/C (MA 31.8% retention) after a 20 000‐cycles accelerated durability test. Systematic studies including density functional theory calculations uncover that the excellent activity is closely related to the optimized ligand and strain effects with the optimized Ni content in this aerogel; the outstanding durability is endowed by the lowered‐down Ni leaching with the optimized Pt/Ni ratio and the inhibited sintering due to its appropriate porosity. This work provides new perspectives on the development of electrocatalysts with both high performance and low cost.

Published: March 2023

AbstractNi‐rich layered oxides are strong candidates for next–generation high‐energy batteries. Unlike batteries in typical laboratory settings, batteries in practical applications are generally not discharged immediately upon reaching a fully charged state, but instead, remain there for varying periods of time before usage. Such a state places immense electrochemical stress on the cathode as much of the Ni‐rich layered oxide degradation mechanisms occur at the highly charged/delithiated state. Differentiating between lab and practical use cases, it is shown for Li[Ni0.90Co0.05Mn0.05]O2 that even the introduction of a short dwell period at the highly charged state leads to substantial differences in cycling performance (capacity retention of 89.4% vs 37.5% at the 100th cycle with or without dwelling, respectively). To overcome the rapid deterioration at high voltage, antimony is used as a dopant to reduce the lattice instability of the high Ni layer structure, especially at the grain boundaries regions, where degradation concentrates at the cathode‐electrolyte interfaces. The resulting Li[Ni0.895Co0.05Mn0.05Sb0.05]O2 cathode material not only maintains stability during extended dwelling periods at the charged state, but also accommodates superior fast‐charge capabilities.

AbstractOat (Avena sativa L.) is the main species used as a companion crop when establishing perennial forages in eastern Canada, and, although other annual species are used, they have not been systematically evaluated. A field study was conducted across five environments to contrast the use of six annual species (berseem clover, Trifolium alexandrinum L.; forage peas, Pisum sativum L.; annual ryegrass, Lolium multiflorum Lamarck; oat; Japanese millet, Echinochloa esculenta [A. Braun] H. Scholz; sudangrass, Sorghum × drummondii [Nees ex. Steud.] Millsp. & Chase) as companion crops for the establishment of alfalfa (Medicago sativa L.)‐timothy (Phleum pratense L.) mixtures. The control treatment consisted of the perennial species seeded without companion crop. Treatments were seeded at three dates and evaluated during the seeding and post‐seeding years. The performance of the six companion crops evaluated herein varied depending on the seeding date and the environment. For a mid‐May to early June seeding total seeding year forage mass was greatest with use of oat, Japanese millet, or sudangrass as companion crops; for a mid‐June to late June seeding with Japanese millet or sudangrass; and for a late July to early August seeding with oat or Japanese millet. These species, however, reduced in some environments seeding year alfalfa or timothy mass compared to a control seeded without a companion crop. Such reduction was also observed in some environments in the first post‐seeding year. Companion crop choice to establish alfalfa–timothy mixtures needs to take into consideration seeding date and forage needs on the short term versus the long term.
Plug‐and‐Play Continuous Variable Measurement‐Device‐Independent Quantum Key Distribution
Authors: Zhou Jian , Feng Yanyan , Shi Jinjing , Shi Ronghua 
Published: March 2023

AbstractIn this paper, a continuous variable (CV) measurement‐device‐independent (MDI) quantum key distribution (QKD) protocol using Gaussian modulated coherent states is proposed. The MDI is first proposed to resist the attacks on the detection equipment by introducing an untrusted relay. However, the necessity of propagation of local oscillator between legitimate users and the relay makes the implementation of CV‐MDI‐QKD highly impractical. By introducing the plug‐and‐play (P&P) technique into CV‐MDI‐QKD, the problems of polarization drifts caused by environmental disturbance and the security loopholes during the local oscillator transmission are solved naturally. The proposed scheme is superior to the previous CV‐MDI‐QKD protocol on the aspect of implementation. The security bounds of the P&P CV‐MDI‐QKD under the Gaussian collective attack are analyzed. It is believed that the technique presented in this paper can be extended to quantum network.

In the current era, the development of robust, eco‐friendly, and highly efficient electrocatalysts for generating hydrogen energy by water electrolysis has become a major challenge. This work explains the electrocatalytic performance of cost‐effective and amiable novel Ni‐BTC‐MWCNTs‐a as an active and effective electrocatalyst for OER in alkaline media. The catalytic activity of the nanocomposite is increased by heat treatment at 400°C temperature for 3 h. Systematic morphological and structural characterization studies of solvothermal synthesized materials were carried out by X‐ray powder diffraction (XRD) analysis, Fourier transform infrared (FTIR) spectroscopy technique, scanning electron microscopy (SEM) analysis, and energy dispersive X‐ray spectroscopy (EDS) analysis techniques. Metal–organic framework (MOF)‐based composites exhibit improved catalytic performance owing to the synergistic effect of Nickel BTC MOF, MWCNTs support, and high‐temperature annealing (400°C). Among all as‐synthesized materials, the annealed Ni‐BTC‐MWCNT‐a exhibits admirable catalytic performance for oxygen evolution reaction (OER) at low value for over potential (η) 243 m V, small Tafel slope value 57 mV dec−1, smaller charge transfer resistance (0.274 Ω), and higher electrochemical active surface area (2000 cm2) with maximum durability for 23 h and utilized as auspicious alternate with excellent catalytic activity in water splitting OER process for producing hydrogen energy at large scale other than highly expensive electrocatalysts of Ir, Ru, Pd, and Pt oxides.
An Examination of the Career Choices of Nursing Graduates After Completing a Perioperative Elective
Authors: Cox Catherine Wilson , Rumble Michelle M. , McNelis Angela M. , Walsh Heather A. 
Published: March 2023

ABSTRACTIn light of the perioperative nursing shortage, academic leaders at a mid‐Atlantic school of nursing and leaders of three health care systems implemented an academic‐practice partnership with the goal of increasing interest in this specialty. Nursing researchers used a descriptive study design to collect data from nursing alumni who participated in the perioperative elective between 2017 and 2021. They found that 25 (38%) of 65 graduates who participated in the elective entered perioperative nursing and 38 (68%) of 56 graduates who answered a question on considering future employment as a perioperative nurse indicated they would do so regardless of their current employment status. Graduates who participated in the elective and experienced a perioperative capstone placement had low anticipated turnover scores and intended to remain in a perioperative position. Academic and health care leaders should consider academic‐practice partnerships as a strategy to recruit and retain perioperative nurses.

AbstractOne of the most remarkable features in sauropod dinosaurs relates to their pneumatized skeletons permeated by a bird‐like air sac system. Many studies described the late evolution and diversification of this trait in mid to late Mesozoic forms but few focused on the origin of the invasive respiratory diverticula in sauropodomorphs. Fortunately, it is possible to solve this thanks to the boom of new species described in the last decade as well as the broad accessibility of new technologies. Here we analyze the unaysaurid sauropodomorph Macrocollum itaquii from the Late Triassic (early Norian) of southern Brazil using micro‐computed tomography. We describe the chronologically oldest and phylogenetically earliest unambiguous evidence of an invasive air sac system in a dinosaur. Surprisingly, this species presented a unique pattern of pneumatization in non‐sauropod sauropodomorphs, with pneumatic foramina in posterior cervical and anterior dorsal vertebrae. This suggests that patterns of pneumatization were not cladistically consistent prior to the arrival of Jurassic eusauropods. Additionally, we describe the protocamerae tissue, a new type of pneumatic tissue with properties of both camellae and camerae. This reverts the previous hypothesis which stated that the skeletal pneumatization first evolved into camarae, and derived into delicate trabecular arrangements. This tissue is evidence of thin camellate‐like tissue developing into larger chambers. Finally, Macrocollum is an example of the gradual evolution of skeletal tissues responding to the fastly specializing Respiratory System of saurischian dinosaurs.
Rational entropy‐based fuzzy fault tolerant control for descriptor stochastic distribution networked control systems with packet dropout
Authors: Li Lifan , Yao Lina 
Published: March 2023

AbstractThe fault tolerant control (FTC) problem based on rational entropy performance criteria is researched for fuzzy descriptor stochastic distribution networked control (SDNC) systems with packet dropout. The independent Bernoulli distribution is employed to describe the packet dropout in the feedback channel. The static model and the dynamic model of descriptor SDNC systems are built up by the rational square‐root fuzzy logic model (FLM) and the T‐S fuzzy model, respectively. When the given output probability density function (PDF) is not known, the minimization of output randomness becomes an important control target. First, the unknown fault is estimated by developing the fuzzy fault estimation observer. Then, the fault tolerant controller with the fault compensation is designed so that the output of the descriptor SDNC system remains with the minimum uncertainty after the fault occurs. A simulation example is supplied to prove the proposed scheme.

AbstractIncorporating redox active units in a 3D porous network is an encouraging strategy to enhance electrochemical performance of organic electrode materials. Herein, a new hybrid composed by phenazine‐based conjugated microporous polymer (IEP‐27‐SR, stand for IMDEA Energy Polymer number 27) and single‐walled carbon nanotubes (SWCNTs) and graphene oxide (RGO) is synthesized, fully characterized and tested electrochemically in different aqueous electrolyte conditions, i. e., at various pH values (1–12) and also with different charge carriers (H+ in acidic, and Li+, Na+, K+ in neutral and alkaline electrolytes). Although the IEP‐27‐SR is found to be very versatile showing very good electrochemistry both in alkaline and acidic solution, it exhibits best specific capacity, redox kinetics and cycle stability in acidic electrolyte. Then encouragingly, when IEP‐27‐SR is combined with an activated carbon (AC) counter electrode to construct a proof‐of‐the‐concept device, the IEP‐27‐SR//AC demonstrates high specific capacity (168 mAh g−1 at 2 C), impressive rate performance (96 mAh g−1 at 60 C) and ultra‐long cycle stability (76 % capacity retention over 28800 cycles at 10 C; 2690 h) in 1 M H2SO4.

Published: March 2023

AbstractThis article describes a comprehensive practical laboratory method for developing an enzyme to more easily measure glyphosate levels in solution. Through this article, undergraduate students of biology majors can conduct research experiments in critical fields by utilizing various techniques, such as chemiluminescence (CL) biosensors with engineered enzymes and are guided in molecular biology laboratories. A glyphosate oxidase mutant library was constructed by DNA shuffling, and a glyphosate oxidase variant with increased glyphosate degradation activity was selected by using a high‐throughput screening assay. Following protein overexpression in Escherichia coli (DE3) and purification by affinity chromatography, the glyphosate oxidase variant protein combined with luminol–H2O2 reaction was constructed as a new CL biosensor for detecting glyphosate in soils.

AbstractBackgroundLoss of HER2 “positivity” can occur in patients with residual disease after neoadjuvant treatment, but the incidence of HER2‐positivity loss after neoadjuvant dual HER2‐targeted treatment plus chemotherapy, the current standard‐of‐care for most early stage HER2‐positive breast cancers, is not well described. Previous studies that report the HER2 discordance rate after neoadjuvant treatment also do not include the novel HER2‐low category. In this retrospective study, we determine the incidence and prognostic impact of HER2‐positivity loss, including the evolution to HER2‐low disease, after neoadjuvant dual HER2‐targeted therapy with chemotherapy.MethodsClinicopathologic data for patients with stage I‐III HER2+ breast cancer diagnosed between 2015 and 2019 were reviewed in this single institution retrospective study. Patients who received dual HER2‐targeted treatment with chemotherapy were included, and HER2 status before and after neoadjuvant therapy was interrogated.ResultsA total of 163 female patients were included in the analysis with a median age of 50 years. A pathologic complete response (pCR as defined by ypT0/is) was achieved in 102 (62.5%) of 163 evaluable patients. Among the 61 patients with residual disease after neoadjuvant therapy, 36 (59.0%) had HER2‐positive and 25 (41.0%) had HER2‐negative residual disease. Of the 25 patients with HER2‐negative residual disease, 22 (88%) of patients were classified as HER2‐low. After a median follow‐up of 3.3 years, patients who retained HER2‐positivity after neoadjuvant treatment had a 3‐year IDFS rate of 91% (95% CI, 91%–100%), while patients who lost HER2‐positivity had a 3‐year IDFS rate of 82% (95% CI, 67%–100%).ConclusionAlmost half of patients with residual disease following neoadjuvant dual HER2‐targeted therapy plus chemotherapy lost HER2‐positivity. The loss of HER2‐positivity may not confer negative prognostic impact, although the results were limited by short follow‐up time. Further research on the HER2 status after neoadjuvant treatment may help guide treatment decisions in the adjuvant setting.

AbstractBackgroundSymptom burden in adolescents and young adults (AYA) with cancer is poorly characterized but impacts quality of life.MethodsAll Ontario, Canada AYA aged 15–29 years at diagnosis between 2010 and 2018 were linked to population‐based healthcare databases, including to Edmonton Symptom Assessment System‐revised (ESAS) scores, an 11‐point scale routinely obtained at the time of cancer‐related outpatient visits and collected provincially. Multistate models estimated mean duration of symptom severity states [none (0) vs. mild (1 vs. 2 vs. 3) vs. moderate (4–6) vs. severe (7–10)], trajectories, and subsequent mortality risk. Variables associated with severe symptoms were also determined.ResultsIn total, 4296 AYA with ≥1 ESAS score within a year of diagnosis were included (median age 25 years). Prevalent moderate/severe symptoms included fatigue (59% of AYA) and anxiety (44%). Across symptom type, AYA reporting moderate symptoms were likelier to subsequently experience improvement versus worsening. Risk of death within 6 months increased with increasing symptom burden and was highest in AYA with severe dyspnea (9.0%), pain (8.0%), or drowsiness (7.5%). AYA in the poorest urban neighborhoods were more likely to experience severe symptoms than in the wealthiest areas, with twice the odds of reporting severe depression [adjusted odds ratio (OR) 1.95, 95th confidence interval (95% CI) 1.37–2.78], pain (OR: 1.94, 95% CI: 1.39–2.70), and dyspnea (OR: 1.96, 95% CI: 1.27–3.02).ConclusionsAYA with cancer experience substantial symptom burden. Risk of death increased with symptom severity. Interventions targeting cancer fatigue and anxiety, and targeting AYA in lower‐income neighborhoods, are likely to improve quality of life in this population.

Published: March 2023

AbstractThis paper introduces the multiple domain‐invariant partial least squares (mdi‐PLS) method, which generalizes the recently introduced domain‐invariant partial least squares method (di‐PLS). In contrast to di‐PLS which solely allows transferring of knowledge from a single source to a single target domain, the proposed approach enables the incorporation of data from an arbitrary number of domains. Additionally, mdi‐PLS offers a high level of flexibility by accepting labeled (supervised) and unlabeled (unsupervised) data to cope with dataset shifts. We demonstrate the application of the mdi‐PLS method on a simulated and one real‐world dataset. Our results show a clear outperformance of both PLS and di‐PLS when data from multiple related domains are available for training multivariate calibration models underpinning the benefit of mdi‐PLS.

Published: March 2023

AbstractFocused exploration of earth‐abundant and cost‐efficient non‐noble metal electrocatalysts with superior hydrogen evolution reaction (HER) performance is very important for large‐scale and efficient electrolysis of water. Herein, a sandwich composite structure (designed as MS‐Mo2C@NCNS) of β‐Mo2C hollow nanotubes (HNT) and N‐doped carbon nanosheets (NCNS) is designed and prepared using a binary NaCl–KCl molten salt (MS) strategy for HER. The temperature‐dominant Kirkendall formation mechanism is tentatively proposed for such a three‐dimensional hierarchical framework. Due to its attractive structure and componential synergism, MS‐Mo2C@NCNS exposes more effective active sites, confers robust structural stability, and shows significant electrocatalytic activity/stability in HER, with a current density of 10 mA cm−2 and an overpotential of only 98 mV in 1 M KOH. Density functional theory calculations point to the synergistic effect of Mo2C HNT and NCNS, leading to enhanced electronic transport and suitable adsorption free energies of H* (ΔGH*) on the surface of electroactive Mo2C. More significantly, the MS‐assisted synthetic methodology here provides an enormous perspective for the commercial development of highly active non‐noble metal electrocatalysts toward efficient hydrogen evolution.
