Coalescing binary neutron stars

The best models for the internal structure of a coalescing binary neutron star are the irrotational Roche-Riemann ellipsoids (IRREs). The IRREs have tidally locked figures but zero circulation in an inertial frame, and are the result of binary evolution in the absence of viscosity. The IRREs differ markedly from the more familiar Roche ellipsoids: where the fluid is static in the corotating frame for the Roche solution, the fluid counterrotates at the orbital frequency for the IRRE solutions, and where the Roche ellipsoids expand along both principal axes in the orbital plane, the IRREs expand along the separation vector and contract in the orthogonal direction
CREEPING FLOW OF VISCOELASTIC FLUIDS THROUGH TAPERED SLIT DIES: AN ANALYTICAL SOLUTION

In the present study, it will be shown that at vanishingly small Reynolds numbers the extensional behavior of a fluid has a strong effect on its kinematics when flowing through a tapered slit die. To show this, the Cauchy equations of motion were simplified using the creeping flow approximation. Assuming the flow to be steady, laminar, two-dimensional, and incompressible, the governing PDEs were reduced to a set of coupled ODEs using a series solution in terms of the powers of 1/r. Two different constitutive equations, both incorporating an extensional parameter, were used in the analysis: (i) the Giesekus model and (ii) the Simplified Phan-Thien-Tanner (SPTT). An analytical solution was found for each fluid model clearly depicting the strong influence of the extensional parameter on the flow becoming non-radial within the channel.
Development planning path of integration of education, production and education from the perspective of big data information fusion

In order to realize the development path planning of education-industry-education integration under the vision of big data information fusion, the development path planning model under the vision of big data information fusion is proposed based on information resource integration scheduling. This paper constructs a big data statistical average analysis model of educational production-education integration development planning under the big data information fusion vision is constructed, and the big data feature extraction and relevance description is taken combined with descriptive statistical analysis results. Pattern recognition and feature screening are carried out by using the average mutual information clustering method for the extracted statistical features of the development planning of education-production-education integration under the vision of big data information fusion, so as to realize the development path planning of education-production-education integration under the vision of big data information fusion based on big data analysis. The results of empirical analysis show that this method has a high level of confidence in the development path planning of the integration of education, production and education from the perspective of big data information fusion, and the evaluation results are accurate and reliable.
Antimicrobial Stewardship Program for Patients in the Hematological Department Receiving Carbapenem Therapy: A Single-Center and Interrupted Time Series Analysis

As antibiotic resistance has become a global problem, the intervention of an antimicrobial stewardship team (AST) is warranted. In hematological disorders, infectious complications are crucial owing to abnormal neutrophil function and decreased cell-mediated immunity. Despite the widespread implementation of AST intervention, the effectiveness of stewardship practices for immunocompromised patients remains uncertain. We determined the effect of AST interventions on carbapenem therapy in the department of hematology. Patients admitted to the department and undergoing carbapenem therapy were enrolled. We compared carbapenem use between the pre-AST (April 2016–March 2018) and post-AST (April 2018–March 2021) periods. Factors associated with long-term carbapenem therapy were investigated. Overall, 515 episodes of carbapenem therapy in 264 patients in the department were evaluated. According to the interrupted time series analysis, the number of days of therapy decreased with AST intervention (β = −0.263, p = 0.011). In multivariate analysis, predictive factors associated with long-term carbapenem therapy (>8 days) were outpatient onset, chronic obstructive pulmonary disease, acute myeloid leukemia, multiple myeloma, and infection with resistant bacteria (such as extended spectrum β-lactamases and AmpC) (95% confidence interval, 1.030–2.818, 1.067–66.667, 1.057–2.782, 0.168–0.742, and 1.382–5.750, respectively). The AST intervention reduced carbapenem use in patients with hematological disorders.
EXISTENCE IN THERMOELASTICITY WITHOUT ENERGY DISSIPATION

In this article we investigate some qualitative aspects of the solutions of the equations of thermoelasticity without energy dissipation. In this sense we establish the suitable framework in which the problem of the linear anisotropic thermoelasticity without energy dissipation is well posed. The fundamental tool with which to obtain the framework is the semigroup of linear operators theory.
Natural-convection heat transfer from regularly ribbed vertical surfaces: Homogenization-based simulations towards a correlation for the Nusselt number

Abstract Free-convection heat transfer from vertical surfaces is widely encountered in engineering applications, yet the role played by surface alterations in the heat transfer process and their practical effectiveness are still points of confusion. In this work, buoyancy-driven flows over periodically ribbed vertical plates of different surface micro-textures are investigated, mainly based on an asymptotic homogenization model through which the expensive resolution of the velocity and thermal fields within the inter-rib regions is bypassed, by imposing equivalent effective boundary conditions at a virtual plane surface. Efficiency of the homogenized simulations in detecting macroscopic behavior of the Nusselt number is first assessed, compared with full feature-resolving simulations in which the effects of complex flow patterns, near and within wall corrugations, on the local Nusselt number are captured. Second, the validated model is used to construct a database of numerical results describing deviations of the average Nusselt number over different ribbed surfaces, relative to a corresponding smooth surface. Under the conditions investigated, it is found that surface roughening generally deteriorates heat transfer from vertical surfaces, with slight enhancement for geometries characterized by low thermal slip, for example, rectangular ribs of narrow inter-rib spaces. Finally, a multiple-regression analysis is conducted to formulate a correlation describing effects of the thermal-slip coefficient, the number of ribs, and the Grashof number on the surface-averaged Nusselt number; accuracy of the proposed correlation is attested via further validation. This paper aims to call attention of the heat transfer society to the ability of the homogenization approach to considerably alleviate the computational requirements for relevant simulations and, thus, to significantly accelerate parametric optimization studies.
Variations of Relative Clause Translation from Indonesian to English

Relative clauses are clauses that explain a noun in order to define or explain a noun further, articles, adjectives, or relative clauses are often used. In an effort to translate from the source language into the target language there is often a strategy used in translating these relative clauses. There are differences in realization in translating these relative clauses, making the researcher wanted to know on how the variations in the equivalent translation of Indonesian relative clauses into English are. There is a novel and its translation used in this research design. The novel that will be used as a source of data in this study is Bumi Manusia by Pramoedya Ananta Toer and its translation ‘The Earth of Mankind’. Data collection was carried out by listening (observing method) and noting (note-taking method) the relative clauses of data on novels in the Indonesian language as the source language and their translation into the target language. The data were then analyzed to find equivalent relative clause variants in Indonesian in English. By analysisng the data it can be found that the variations of relative clause translation from Indonesian to English are (1) relative clauses (with relative pronoun who, which, that, whose, whom), (2) adjectives, (3) present participle, (4) past participle, (5) noun phrase, (6) prepositional phrase, (7) noun class, and (8) verb.
Effect of martensitic transformation and magnetic field on transport properties of Ni-Mn-Ga and Ni-Fe-Ga Heusler alloys

We study the magnetic-field influence on the martensitic transformation temperatures and the accompanying anomaly in the resistivity by extensive measurements of the temperature dependencies of resistivity of several Ni-Mn-Ga and Ni-Fe-Ga alloys. A low-field minimum of the martensitic transformation temperature versus magnetic-field curves is observed for single and polycrystalline Ni-Mn-Ga alloys. This minimum is confirmed by magnetization loop measurements showing a magnetic anisotropy contribution to the ordinary Clausius-Clapeyron relationship which describes the martensitic transformation. This minimum did not appear for Ni-Fe-Ga polycrystalline alloys because in this case the difference in the magnetic anisotropy of relevant phases is small. We did not find any systematic behavior of the magnetoresistance related to the phase in which it is measured. In the vicinity of the martensitic transformation, the magnetoresistance exhibits a peaklike behavior which is explained in terms of the combined influence of the zero-field resistivity anomaly at the transition and the magnetic-field-induced shift of the transformation temperature.
The proton cyclotron instability and the anisotropy/β inverse correlation

Spacecraft observations in the strongly compressed subsolar magnetosheath show an inverse correlation between the proton temperature anisotropy (T{sub {perpendicular}p}/T{sub {parallel}p} > 1 where {perpendicular} and {parallel} denote directions perpendicular and parallel to the background magnetic field) and the parallel proton {beta}({beta}{sub {parallel}p}). This manuscript uses one-dimensional hybrid simulations of the proton cyclotron anisotropy instability in homogeneous electron-proton plasmas to study this correlation which may represent a limited closure relation for fluid theories of anisotropic space plasmas. The emphasis is on driven simulations which increase the temperature anisotropy by periodically reducing the magnetic-field-aligned velocities of the protons. The late-time states from ensembles of both initial value and driven simulations yield very similar expressions for the proton anisotropy/{beta}{sub {parallel}p} inverse correlation, and provide a basis for explaining differences between sheath observations from different spacecraft. The driven simulations also yield expressions for the maximum instability growth rate and the fluctuating field energy as functions of {beta}{sub {parallel}p} and a parameter characterizing the anisotropy driver. 50 refs., 5 figs.
Equivalent Circuit Model for High-Power Lithium-Ion Batteries under High Current Rates, Wide Temperature Range, and Various State of Charges

The most employed technique to mimic the behavior of lithium-ion cells to monitor and control them is the equivalent circuit model (ECM). This modeling tool should be precise enough to ensure the system’s reliability. Two significant parameters that affect the accuracy of the ECM are the applied current rate and operating temperature. Without a thorough understating of the influence of these parameters on the ECM, parameter estimation should be carried out manually within the calibration, which is not favorable. In this work, an enhanced ECM was developed for high-power lithium-ion capacitors (LiC) for a wide temperature range from the freezing temperature of −30 °C to the hot temperature of +60 °C with the applied rates from 10 A to 500 A. In this context, experimental tests were carried out to mimic the behavior of the LiC by modeling an ECM with two RC branches. In these branches, two resistance and capacitance (RC) are required to maintain the precision of the model. The validation results proved that the semi-empirical second-order ECM can estimate the electrical and thermal parameters of the LiC with high accuracy. In this context, when the current rate was less than 150 A, the error of the developed ECM was lower than 3%. Additionally, when the demanded power was high, in current rates above 150 A, the simulation error was lower than 5%.
Aberrant alteration of peripheral B lymphocyte subsets in hepatocellular carcinoma patients

Although B lymphocytes are widely known to participate in the immune response, the conclusive roles of B lymphocyte subsets in the antitumor immune response have not yet been determined. Single-cell data from GEO datasets were first analyzed, and then a B cell flow cytometry panel was used to analyze the peripheral blood of 89 HCC patients and 33 healthy controls recruited to participate in our research. Patients with HCC had a higher frequency of B10 cells and a lower percentage of MZB cells than healthy controls. And the changes in B cell subsets might occur at an early stage. Moreover, the frequency of B10 cells decreased after surgery. Positively correlated with B10 cells, the elevated IL-10 level in HCC serum may be a new biomarker in HCC identification. For the first time, our results suggest that altered B cell subsets are associated with the development and prognosis of HCC. Increased B10 cell percentage and IL-10 in HCC patients suggest they might augment the development of liver tumors. Hence, B cell subsets and related cytokines may have predictive value in HCC patients and could be potential targets for immunotherapy in HCC.
The Computational Power of ℳ︁ω

We prove that the Kleene schemes for primitive recursion relative to the μ-operator, relativized to some nondeterministic objects, have the same power to express total functionals when interpreted over the partial continuous functionals and over the Kleene-Kreisel continuous functionals. Relating the former interpretation to Niggl's ℳω we prove Nigg's conjecture that ℳω is strictly weaker than Plotkin's PCF + PA.
Optical design of the ultraviolet imaging spectrograph for the Cassini mission to Saturn

When the Cassini spacecraft arrives at Saturn early in the next century it will carry an UltraViolet Imaging Spectrograph (IJVIS) designed and built by the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado. Observations made with the UVIS will support a broad set of scientific investigations including spectroscopy, imaging, and occultations. The UVIS consists of three spectroscopic channels covering the wavelength ranges 55—i 15 nm, 1 15—190 nm, and 160— 320 nm. Each channel has an off-axis parabolic telescope followed by a toroidal grating spectrograph and an imaging microchannel plate-CODACON detector. Mirror coatings and detector photocathode materials optimize the sensitivity of each channel for its particular wavelength range. Spectrograph entrance slit mechanisms provide four independent spectral and spatial resolution modes for each of the three channels. A fourth optical train consisting of an off-axis parabolic telescope and solar blind photomultiplier tube with a CsI photocathode provides a high sensitivity photometer mode within the UVIS. The UVIS configuration was selected as a balanced solution to a large number of engineering and scientific constraints. We describe these constraints, the optical design, and the anticipated performance of the instrument.
Fixed point spaces in actions of classical algebraic groups

Let G be a simple classical algebraic group over an algebraically closed field K of characteristic p ? 0, and let H be a maximal closed non-subspace subgroup of G. Given such a pair (G, H), we obtain a close to best possible upper bound for the ratio dim(xG ? H) / =dim xG, where x ? G is a semisimple or unipotent element of prime order. We apply this result to the study of fixed point spaces.
Subpicosecond light pulses from a synchronously mode‐locked dye laser with composite gain and absorber medium

We report the generation of subpicosecond light pulses in a cw mode‐locked Oxazine 750 dye laser, utilizing combined synchronous pumping and saturable dye absorption effects. The latter were realized by either fractional cavity length configurations or composite gain‐absorber media, which allowed stable operation in the tuning range 750–835 nm.
Comparative Transcriptomics Profiling of Perennial Ryegrass Infected with Wild Type or a ΔvelA Epichloë festucae Mutant Reveals Host Processes Underlying Mutualistic versus Antagonistic Interactions

Epichloë species form bioprotective endophytic symbioses with many cool-season grasses, including agriculturally important forage grasses. Despite its importance, relatively little is known about the molecular details of the interaction and the regulatory genes involved. VelA is a key global regulator in fungal secondary metabolism and development. In previous studies, we showed the requirement of velA for E. festucae to form a mutualistic interaction with Lolium perenne. We showed that VelA regulates the expression of genes encoding proteins involved in membrane transport, fungal cell wall biosynthesis, host cell wall degradation, and secondary metabolism, along with several small-secreted proteins in Epichloë festucae. Here, by a comparative transcriptomics analysis on perennial ryegrass seedlings and mature plants, which are endophyte free or infected with wild type (mutualistic interaction) or mutant ΔvelA E. festucae (antagonistic or incompatible interaction), regulatory effects of the endophytic interaction on perennial ryegrass development was studied. We show that ΔvelA mutant associations influence the expression of genes involved in primary metabolism, secondary metabolism, and response to biotic and abiotic stresses compared with wild type associations, providing an insight into processes defining mutualistic versus antagonistic interactions.
DQN based joint computing offloading and resource allocation for network slicing in F-RAN

Edge computing and network slicing are two key technologies to reduce communication latency and improve network flexibility in fog radio access network (F-RAN). Due to the existence of the massive potential offloading decisions, in this paper, we develop a joint computing offloading and resource allocation strategy to minimize the total energy consumption of the cloud-edge system. In order to meet the quality of service (QoS) of different devices, two different radio access network (RAN) slices are designed. Besides, considering the curse of dimensionality caused by the explosive growth of the UEs, we propose a deep Q-learning (DQN) algorithm, which uses value function approximation to compress the status dimension. Moreover, to reduce the complexity of the algorithm, the problem is divided into two subproblems, which are joint radio resource allocation and fog access point (FAP) selection problem and cloud side task forwarding problem and solved by DQN and greedy algorithm separately. Through simulation, we demonstrate that the method proposed in this paper can effectively reduce the total system energy consumption and shorten the convergence time.
Stochastic heating in field-reversed low pressure discharges

Capacitive and inductive stochastic heating rely on the repeated interaction of electrons with a localized oscillating electromagnetic structure, such as an electric sheath or a magnetic skin depth. The periodic interaction with a third type of localized structure, the zero line of a linear magnetic field, also provides an efficient means to sustain radio frequency low pressure discharges. In order to calculate the stochastic heating rate, the relevant variables are identified and the electron orbits are classified. Then the kinetic theory of collisionless heating in this type of magnetized discharge is developed. The stochasticity threshold and the quasilinear equation are derived to evaluate the collisionless absorption. The analytical scaling of the heating threshold and the collisionless power absorption are expressed and discussed as a function of the discharge parameters.
The relative utility of current observation systems to global‐scale NWP forecasts

We study 20 cases in which 60‐hour Numerical Weather Prediction (NWP) of specific synoptic events have been markedly improved by observations made during the final 15 hours prior to the forecast initial time. For each case, the observing systems which played major rǒles in improving the accuracy of the forecast mean‐sea‐level pressure (m.s.1.p.) field are identified using a series of Observation System Experiments. The relative utility of each observation type is then assessed according to the frequency, over all cases, with which it delivers a major beneficial impact.
On digital theorizing, clickbait research, and the cumulative tradition

The pursuit of novel and indigenous digital theories is a thought-provoking call by Grover and Lyytinen. Such a piece is direly needed, and we hope it will spark a reinvigoration of the field. However, despite its many merits and our alignment with its message, we have two comments or caveats for readers of their piece. These are—a) a need to re-emphasize the value of attending to the cumulative tradition in our pursuit of digital theorizing, and relatedly b) an unreflective reading of the paper may risk mobilizing IS scholarship towards clickbait research. We further highlight three anchors that future scholarship can consider in attending to these issues a) problematization anchor, b) implications anchor, and c) boundary-spanning anchor. With these points, we add more volume to amplify the message of G&L and offer suggestions for pursuing innovative digital theories that go beyond ephemeral theorizing.
Nonlinear Averaging Axioms in Financial Mathematics and Stock Price Dynamics

In the presence of an uncertainty factor, that is, if some variable X assumes several values $x_1,\ldots,x_n$ rather than a single value, one usually performs an averaging over these values with some coefficients (measures) $\alpha_i$ such that $\sum_{i=1}^n\alpha_i=1$ and sets $y=\sum\alpha_ix_i$. For an equity market, there arises a nonlinear averaging for y. We consider an averaging of the form $f(y)=\sum\alpha_if_i(x_i)$. Starting from four natural axioms, we prove that either the above-mentioned linear averaging holds, or $y=\log\sum_{i=1}^ne^{x_i}$. An example of a stock price breakout under this summation is given.
High-frequency limits of superconducting tunnel junction mixers

We have investigated high‐frequency limits of superconducting quasiparticle mixers from experiments on Al/Al‐oxide‐In/Al (or Ag) tunnel junctions, and from calculations based on Tucker’s quantum theory of mixing (QTM). The small superconducting energy gap of Al enabled us to study mixer performance at around the junction gap frequency, fg =(Δ1+Δ2)/h≊87 GHz, of superconductor‐insulator‐superconductor (SIS) mixers, and at twice the junction gap frequency for S‐I‐normal metal (SIN) mixers ( fg =Δ1/h) with available millimeter wave sources. Because of the low transition temperature of Al (Tc ≊1.3 K), a dilution refrigerator was used for providing temperatures below 1 K. The best mixer conversion efficiency was obtained for a low‐resistance (∼34 Ω) six‐junction array SIS mixer operated at f/fg ≊1 (in this case 73 GHz). The coupled single sideband conversion gain (with no image rejection) was −13.8 dB and the available conversion gain was estimated to −8.4 dB. Complicating nonequilibrium phenomena made it dif.
