Dynamics of supercooled liquids and the glass transition

Closed nonlinear equations are derived for a self-consistent treatment of density propagation, self-diffusion and current relaxation in a classical monatomic fluid. The solution for a hard-sphere model system brings out a phase transition to a glass at the packing fraction 0.516. Approaching the transition from the glass side the particle mean-square displacement increases to a finite value. A simplified model is analysed in detail. Approaching the transition from the liquid side the diffusivity is predicted to decrease to zero with a power law with exponent 1.76 which the authors find to agree well with some experimental data. The low-frequency density spectrum is found to consist of two contributions; one is an elastic line of the frozen structure on the glass side, which then decays to a narrow diffusion broadened quasielastic peak on the fluid side; the other part is described by a dynamical scaling law and it yields in particular a spectrum diverging at the glass point with certain exponents.
Merkel Cell Carcinoma in Kidney Transplant Recipients

Merkel cell carcinoma (MCC) is an uncommon form of skin neoplasm with poor histological differentiation and an aggressive disease process, leading to high recurrence and mortality. There are multiple risk factors in which being in an immunocompromised state is a significant factor, and the discovery of Merkel cell polyomavirus (MCPyV) since 2008 has strengthened causal associations between MCC and immunosuppression. Individuals who have undergone kidney transplantation are therefore more susceptible to having MCC, secondary to post-transplant immunosuppression which plays a vital role in reducing the risk of transplant kidney rejection. Over recent years a rise in the incidence of MCC following kidney transplantation is noted, with increased reporting of such cases. Whilst localized MCC is observed, MCC metastasis to the lymphatic system, brain, bone, liver, lung, and heart has been previously observed in patients with transplanted kidneys. Kidney metastasis is less common and has been only reported in recent years with greater frequency. The management of aggressive, metastatic MCC has historically been palliative, and prognosis is poor. Recently, the use of immune checkpoint inhibitors for metastatic MCC in multi-center phase II clinical trials have shown promising survival outcomes and have been approved for use in countries such as the United States as a first-line treatment. In this review we will explore the potential pathophysiological processes of MCC manifesting post-kidney transplantation. We will then evaluate the epidemiology of MCC within the context of kidney transplantation, before discussing the various clinical presentations, diagnostic measures, surveillance strategies, and current treatment options as well as future directions to best manage MCC in kidney transplant recipients.
Normal Form of Antiunitary Operators

Antiunitary operators are characterized in a manner similar to the characterization of unitary operators by their characteristic vectors and characteristic values. It is shown that a complete orthonormal set of vectors can be defined, some of which are invariant under the antiunitary operator. The rest of the vectors, which are always even in number, form pairs in such a way that the antiunitary operator transforms each member of a pair into a multiple of the other member of the same pair [Eq. (11)]. The extent to which the vectors of the orthonormal set are determined by the antiunitary operator is ascertained and the number of free parameters in the various cases of degeneracy found.
Monolithic GaAs/AlAs optical bistable étalons with improved switching characteristics

Compact bistable GaAs etalons with epitaxial GaAs/AlAs Bragg reflectors have been fabricated by metallorganic vapor phase epitaxy. Their monolithic structure is convenient for further technological steps. It has been found that the good thermal conductivity of the mirror layers allows more efficient heat sinking and leads to improved switching characteristics. A 2:1 contrast ratio and a 20 ns switching time have been obtained in the reflective mode, with a 4 mW threshold power and a strongly reduced dependence of the switch‐off threshold upon incident pulse duration.
A Cross-Sectional Analysis of Health Literacy and Compliance to Treatment in Organ Transplant Recipients

This study was conducted to determine the correlations between health literacy, transplant effects, and compliance to treatment in organ transplant recipients and to identify the factors influencing compliance to treatment. The participants (n = 130; males = 66.9%; mean age = 56.4 years) were organ transplant recipients visiting an organ transplantation center in Seoul, South Korea. The regression model explained 32% of the variance in participants’ compliance to treatment. Among the health literacy variables, “Scale 3: Actively managing my health” (β = 0.38, p = 0.001) and “Scale 4: Social support for health” (β = 0.25, p = 0.019) had a significant effect on compliance to treatment. In this study, health literacy was identified as a key factor influencing compliance to treatment. Therefore, patients’ health literacy should be assessed prior to transplantation to identify potential high-risk patients for treatment nonadherence. In addition, after transplantation surgery, patient-tailored interventions should be developed and provided for self-management that reflects the patient’s health literacy level to ultimately enhance patient outcomes.
Pancreatic Cystic Tumors: A Single-Center Observational Study

Background and Objectives: The aim of the study was to analyze the prevalence and characteristics of pancreatic cystic tumors (PCTs). Material and Methods: A retrospective analysis of the medical records of 124 patients, 102 (69%) women and 46 (31%) men, who had undergone surgery for pancreatic cystic tumors in 2014–2018. Among 148 pancreatic cysts, 24 (16%) were non-neoplasmatic and 124 (84%) were neoplasmatic. The neoplasmatic cysts (n = 124) were included in our analysis. There were five main types of PCTs: IPMN (intraductal papillary mucinous neoplasm) (n = 45), MCN (mucinous cystic neoplasm) (n = 30), SCN (serous cystic neoplasm) (n = 28), SPN (solid pseudopapillary neoplasm) (n = 8), and CPEN (cystic pancreatic endocrine neoplasm) (n = 8), as well as mixed-type tumors (n = 5). Results: A statistically significant dependency between PCT type and age was proven (p= 0.0001): IPMNs were observed in the older group of patients with an average age of 66.12 (40–79) years while SPNs were noted in the youngest group of patients with an average age of 36.22 (22–55) years. A statistically significant association between PCT type and gender (p = 0.0001) was found: IPMNs occurred among 24 (53.33%) men and 21 (46.6%) women. In the MCN and SPN groups, all patients were female (100%). Among the SCN group, the majority were women (27 (96.43%)), and there was only 1 (3.57%) man. A statistically significant dependency between PCT type and size was proven (p = 0.0007). The mean size of IPMNs was the smallest 2.95 (0.6–10 cm) and the mean size of MCNs was the largest 6.78 (1.5–19 cm). A statistically significant dependency between PCT type and tumor location was proven (p = 0.000238). The most frequent location of IPMN was the pancreatic head: 27 (60%). MCN was most frequently located in the pancreatic tail (18 (60%)). Most (10/28) SCNs were found in the pancreatic tail (10 (35.71%)). CPENs were most frequently located in the pancreatic tail (three (37.5%)) and pancreatic body and tail (three (37.5%)). SPNs were located commonly in the pancreatic head (five (62.5%)). The type of surgery depended on the tumor location. The most frequent surgery for IPMNs was pancreatoduodenectomy (44.4%), while for MCNs and SCNs, it was distal pancreatectomy (81%). The postoperative morbidity and mortality were 34.68% and 1.61%, respectively. Postoperative pancreatic fistula (POPF) was the most frequent (29%) complication. Conclusions: IPMN was the most frequent resected PCT in our material. A statistically significant association between the type of cyst and location within the pancreas, size, local lymph node involvement, and patient’s age and sex was proved. POPF was the most frequent postoperative complication. In patients with PCTs, due to substantial postoperative morbidity, adequate patient selection, considering both the surgical risk as well as the long-term risk of malignant transformation, is very important during qualification for surgery.
Ion frictional heating at high latitudes and its possible use for an in situ determination of neutral thermospheric winds and temperatures

We have used the Atmosphere Explorer C data base of ion temperature and ion drift velocities to study the long recognized principle that large scale convection electric fields are responsible for substantial enhancements in the ion temperature at high latitudes. As had been indicated by various authors previously, our study shows that there is a clear relationship between large ion velocities and ion temperature enhancements. Furthermore, with the help of a more quantitative study, we find that, since ion heating is sensitive to the relative motion between the ion and neutral gases we can use the ion temperature and drift measurements to extract neutral wind and neutral temperature information along the satellite track. From a study of several examples we conclude that the present approach can be used with varying degrees of accuracy for the diagnostic of thermospheric dynamical properties above 300 km when those properties are not measured directly. When neutral dynamical properties are measured our approach could be used for a detailed study of the ion energy balance at high latitudes.
Leaders’ Role in Shaping Followers’ Well-Being: Crossover in a Sample of Nurses

The link between well-being at work and leadership has received considerable attention. Leaders have the power to influence followers not only due to formal position, but also their positive behaviors could reinforce the followers’ positive working experience. Following the crossover model (Westman, 2001), this study investigates whether leaders’ work-related positive psychological states (i.e., work engagement) cross over to those of the followers (i.e., work engagement and job satisfaction) through the mediation of the latter’s perception of transformational leadership. We used MPlus 8 to test two multilevel mediations in a sample of 1505 nurses nested in 143 groups led by as many leaders (87.19% of nurses and 56.50% of head nurses of the entire population). Results show that while there is not a crossover of leader work engagement to nurse work engagement, manager work engagement can cross over to nurse job satisfaction, enhancing their well-being through transformational leadership behaviors. This study adds further insights both on crossover theory and on the importance of leaders in expanding and transferring resources to followers at work. Fostering work engagement at a managerial level in the healthcare sector could be the driver to facilitate the well-being of nurses at work, address negative outcomes, and promote positive ones.
DREAMPlace 4.0: Timing-Driven Placement With Momentum-Based Net Weighting and Lagrangian-Based Refinement

Optimizing timing is critical to the design closure of integrated circuits (ICs). However, most existing algorithms for circuit placement focus on the optimization of wirelength instead of timing metrics. This article presents a timing-driven placement framework. It consists of a global placement stage based on net weighting with momentum, and a detailed placement stage based on the Lagrangian multipliers. By improving the preconditioners and timing engines to facilitate net weighting and discrete local search, we have achieved superior timing improvement on benchmarks from ICCAD 2015 contest, including worst negative slack (WNS) and total negative slack (TNS).
Moral Development during Emerging Adulthood: Theoretical Considerations and a Neo-Aristotelian Approach

Moral development during emerging adulthood is a topic of growing interest. Several different theories within the study of human development appear to converge on this point of inquiry, as the study of moral development during emerging adulthood recruits different areas of expertise. This paper explores different theoretical approaches to the study of moral development during emerging adulthood and demonstrates the need for interdisciplinary collaboration. The overall shape of the exploration is governed by broad philosophical considerations grounded in the ethics of Aristotle. First, Aristotle’s ideas are adapted to a developmental paradigm, providing an overarching theory of moral development. Second, the study of moral development during emerging adulthood is situated within the relational developmental system metatheory of human development. These first two theories provide a framework for “moral” and “development,” respectively. Additional conceptual and theoretical issues are addressed as they arise, including moral identity and the link between virtue and happiness.
The Effects of Irrigation, Genotype and Additives on Tef Silage Making

Simple Summary Tef is a multi-harvest crop with high production capacity and outstanding fodder quality. Our overall goal is to establish tef as a multi-harvest summer fodder crop. Here, we report on the effects of irrigation (75% vs. 100%), genotype (RTC-2, RTC-119, RTC-361, and RTC-400), and additives; heterofermentative inoculum, molasses, and molasses + heterofermentative inoculum on tef silage making and silage quality. Our results showed for the first time that tef can be ensiled. Most of tef silage qualitative parameters were better at 75% irrigation than 100%, and additives treatments improved the silage parameters; additives lowered silage pH and ammonia nitrogen, but increased in vitro dry matter digestibility, lactic acid, lactic acid bacteria, and crude protein content of tef silage. Abstract Tef is known as a multi-harvest crop with high production capacity and outstanding fodder quality. Hence, our overall goal is to develop tef as a new multi-harvest summer crop that can maintain high-quality feed and contribute to both field crops and the livestock industry in Israel. In this study, we aimed to evaluate the ability to preserve tef as silage. Four tef genotypes grown under well-watered (100%) and water-limited (75%) irrigation regimes were harvested at grain filling stage and ensiled with either no additives (control, CTL), or with heterofermentative inoculum (HI), molasses (MOL), and both MOL + HI. Our results showed for the first time that tef could be ensiled, although water-soluble carbohydrates (WSC) were lower than those in corn, “the perfect ensiling crop”. Most of the tef silage qualitative parameters were better at water-limited irrigation. Additives HI or MOL or MOL + HI also improved silage parameters, e.g., lowered pH and ammonia nitrogen content, but increased in vitro dry matter digestibility, lactic acid and crude protein content, and lactic acid bacteria counts of tef silage. The current results imply increasing the diversity of local ruminant fodder crops, ensuring high-quality feed supply during the summer.
Robust Sliding Mode Motion Control for Nonlinear Piezo-Driven Micropositioning Systems with Time-Varying Uncertainties

Piezo-driven micropositioning systems (PMSs) are prevalent in the high-precision manipulation fields, but also suffer from undesired nonlinear time-varying uncertainties, such as hysteresis, and parameter perturbation. To this end, this article proposes a novel sliding-mode-based robust control for a class of SISO nonlinear PMSs with time-varying uncertainties. Firstly, through a terminal-sliding-mode (TSM) surface with continuous, nonsingular, and finite-time convergence properties, a fast nonsingular TSM (FNTSM) control law is developed. Moreover, to avoid the shortage of the FNTSM control depending on the boundary information of system uncertainties, the Fourier series-based function estimation technique is adopted for dynamic approximation, and its approximation error is further compensated by the fuzzy logic system online. The updating laws of Fourier coefficients and fuzzy adjustable parameters are finally obtained via the Lyapunov stability theory. Numerical simulation results validate the reliability and superiority of the developed control strategy in comparison with the existing SMC methods.
Fluid-Thermal Response of Spherical Dome Under a Mach 6.59 Laminar Boundary Layer

The coupledfluid–thermal response of a nominally rigid aluminum spherical dome fixed to a ceramic panel holder placed in a Mach 6.59 laminar boundary layer is examined. The compressible Navier–Stokes equations for a thermally perfect gas and the transient heat equation in the structure are solved simultaneously using two highfidelity solvers coupled at the solid–fluid interface. The geometry and flow conditions correspond to those investigated in the 8-Foot High Temperature Tunnel at NASA Langley during testing of metallic thermal protection systems for the National Aerospace Plane for which experimental heat flux data are available. Predicted surface heat fluxes arewithin 10%of themeasured values in the dome interiorwith greater differences foundnear the dome edges where uncertainties concerning the experimentalmodel’s construction likely influence the thermal dynamics. On the flat panel holder, the local surface heat fluxes approach those on the windward dome face due to a dome-induced horseshoe vortex scouring the panel’s surface. Comparisons with simplermodels of heat transfer indicate they fail to be accurate in regionswhere the dome-influencedflow impacts the ceramic panel. Cumulative effects offlow-thermal coupling at later simulation times on panel drag and surface heat transfer are quantified.
Overview and status of the Kepler Mission

The Kepler Mission is a search for terrestrial planets specifically designed to detect Earth-size planets in the habitable zones of solar-like stars. In addition, the mission has a broad detection capability for a wide range of planetary sizes, planetary orbits and spectral types of stars. The mission is in the midst of the developmental phase with good progress leading to the preliminary design review later this year. Long lead procurements are well under way. An overview in all areas is presented including both the flight system (photometer and spacecraft) and the ground system. Launch is on target for 2007 on a Delta II.
PML implementation in the ADI‐FDTD method using bilinear approximation

Bilinear approximation is employed to implement the perfectly matched layer (PML) absorbing boundary condition in the alternating direction implicit (ADI) finite‐difference time‐domain (FDTD) method. Numerical examples show that this implementation is effective and unconditionally stable. © 2006 Wiley Periodicals, Inc.

Systematic Review of Nutrition Interventions to Improve Short Term Outcomes in Head and Neck Cancer Patients

Simple Summary Head and neck cancer (HNC) patients are at increased risk of malnutrition prior to and during radiation, chemotherapy, and surgical treatment. Nutrition intervention is recommended by several organizations, but is not part of treatment guidelines. We conducted a systematic review of randomized controlled trials in HNC patients to determine whether nutrition interventions prevented weight loss, and improved quality of life, nutrient intake, and treatment tolerance. Interventions, including medical nutrition therapy provided by a registered dietitian and including oral nutrition supplements, had the most favorable outcomes in these patients. Abstract Head and neck cancer (HNC) is associated with high rates of malnutrition. We conducted a systematic review and descriptive analysis to determine the effects of nutrition interventions on the nutrition status, quality of life (QOL), and treatment tolerance of HNC patients. PubMed, Web of Science, and Embase were searched to include all potentially relevant studies published between 2006–2022. Meta-analysis was not conducted due to heterogeneity of study designs and outcomes reported. Studies were categorized as nutrition interventions: (1) with oral nutrition supplements (ONS) and medical nutrition therapy (MNT) delivered by an RD; (2) with enteral nutrition (EN) support and MNT delivered by an RD; (3) with motivational interviewing and no ONS or EN; and (4) with ONS and no RD. Seven articles met inclusion criteria. Studies measured outcomes from immediately following treatment to 12 months post-treatment. Interventions resulted in benefits to lean mass/weight maintenance (three studies), QOL (two studies), nutrient intake adequacy (one study) and treatment tolerance (two studies). Nutrition counseling by a registered dietitian leads to improved nutrition status and QOL. Further research is needed to determine best practices related to timing of initiation, duration of nutrition intervention, as well as frequency of dietitian follow-up.
Tb3+ and Bi3+ Co-Doping of Lead-Free Cs2NaInCl6 Double Perovskite Nanocrystals for Tailoring Optical Properties

Lead halide perovskites have achieved remarkable success in various photovoltaic and optoelectronic applications, especially solar cells and light-emitting diodes (LEDs). Despite the significant advances of lead halide perovskites, lead toxicity and insufficient stability limit their commercialization. Lead-free double perovskites (DPs) are potential materials to address these issues because of their non-toxicity and high stability. By doping DP nanocrystals (NCs) with lanthanide ions (Ln3+), it is possible to make them more stable and impart their optical properties. In this work, a variable temperature hot injection method is used to synthesize lead-free Tb3+-doped Cs2NaInCl6 DP NCs, which exhibit a major narrow green photoluminescence (PL) peak at 544 nm derived from the transition of Tb3+ 5D4→7F5. With further Bi3+ co-doping, the Tb3+-Bi3+-co-doped Cs2NaInCl6 DP NCs are not only directly excited at 280 nm but are also excited at 310 nm and 342 nm. The latter have a higher PL intensity because partial Tb3+ ions are excited through more efficient energy transfer channels from the Bi3+ to the Tb3+ ions. The investigation of the underlying mechanism between the intrinsic emission of Cs2NaInCl6 NCs and the narrow green PL caused by lanthanide ion doping in this paper will facilitate the development of lead-free halide perovskite NCs.
Longitudinal D-Dimer Trajectories and the Risk of Mortality in Abdominal Trauma Patients: A Group-Based Trajectory Modeling Analysis

This study aimed to identify the long-term D-dimer trajectory patterns and their associations with in-hospital all-cause mortality in abdominal trauma patients. This is a retrospective cohort study of general adult abdominal trauma patients admitted to Jinling Hospital (Nanjing, China) between January 2010 and April 2020. Group-based trajectory modeling was applied to model D-dimer trajectories over the first 50 days post-trauma. A multivariable logistic regression was performed to estimate the associations between D-dimer trajectories and in-hospital all-cause mortality. A total of 309 patients were included. We identified four distinct D-dimer trajectories: group 1 (57.61%; “stable low”), group 2 (28.16%; “moderate-decline”), group 3 (8.41%; “high-rapid decline”), and group 4 (5.83%; “high-gradual decline”). The SOFA score (p = 0.005) and ISS (p = 0.001) were statistically higher in groups 3 and 4 than in groups 1 and 2. The LMWH and UFH did not differ between groups 3 and 4. Compared with the patients in group 1, only the patients in group 4 were at a higher risk of in-hospital all-cause mortality (OR = 6.94, 95% CI: 1.20–40.25). The long-term D-dimer trajectories post-trauma were heterogeneous and associated with mortality. An initially high and slowly-resolved D-dimer might function as the marker of disease deterioration, and specific interventions are needed.
