Looking outside and addressing the crucial issues

Communication educators have done many things well, the cumulative impact of which has served our discipline well. However, there have also been areas where we could have done better. For this forum, I am focusing on the latter, not to dismiss what we do well, but because it offers an opportunity for our discipline. We are in a period of significant change in higher education, a situation that entails both risk and opportunity. The thinner margins and need to demonstrate appreciable return on investment for today’s college students are a challenge for the industry as a whole. But these factors can work in our field’s favor if we understand the opportunity and make the right moves. To do so, we must improve at:
Study on Transport Properties of Chitosan Membrane in Different Types of Electrolytes

In this study, the electrical properties of chitosan membrane in different types of electrolytes were investigated by analyzing the current-voltage (I‑V) curve. The membrane used was chitosan membrane 2%. The different electrolyte solutions used were KCl, HCl, MgCl 2 , CaCl 2 and AlCl 3 at concentrations of 0.025 M. The I-V experiments were done using a two-compartment cell, which contained two working electrodes made of platinum connected to a DC current source and two Ag/AgCl reference electrodes connected to a voltmeter. All experiments were conducted at an ambient temperature of 28.7 °C. Water uptake (hydrophilicity) and Fourier transform infrared (FTIR) measurements were also studied in this research. The I-V curves show the ohmic behavior of the membrane. The resistance of the membrane was higher in the electrolyte solutions with larger Stokes radii and lower in the electrolyte solutions with larger diffusion coefficients, except in the HCl solution. These results indicate that the I-V curve shapes are affected by the type of electrolyte solution used for the chitosan membrane transport. The hydrophilicity of the membrane was improved after exposure to the electrolyte solutions. The FTIR analysis revealed a new peak at about 677 cm -1 , which indicates the formation of C-Cl groups in the used membranes.
Integration of Euclidean and path distances in hippocampal maps

The hippocampus is a key region for forming mental maps of our environment. These maps represent spatial information such as distances between landmarks. A cognitive map can allow for flexible inference of spatial relationships that have never been directly experienced before. Previous work has shown that the human hippocampus encodes distances between locations, but it is unclear how Euclidean and path distances are distinguished. In this study, participants performed an object-location task in a virtual environment. We combined functional magnetic resonance imaging with representational similarity analysis to test how Euclidean and path distances are represented in the hippocampus. We observe that hippocampal neural pattern similarity for objects scales with Euclidean as well as path distance between object locations, suggesting that the hippocampus integrates both types of distances. One key characteristic of cognitive maps is their adaptive and flexible nature. We therefore subsequently modified path distances between objects using roadblocks in the environment. We found that hippocampal pattern similarity between objects adapted as a function of these changes in path distance, selectively in egocentric navigators but not in allocentric navigators Taken together, our study supports the idea that the hippocampus creates integrative and flexible cognitive maps.
DsrMKJOP is the terminal reductase complex in anaerobic sulfate respiration

Microbial dissimilatory sulfate reduction is a key process in the Earth biogeochemical sulfur cycle. In spite of its importance to the sulfur and carbon cycles, industrial processes and human health, it is still not clear how reduction of sulfate to sulfide is coupled to energy conservation. A central step in the pathway is the reduction of sulfite by the DsrAB dissimilatory sulfite reductase, which leads to the production of a DsrC-trisulfide. A membrane-bound complex, DsrMKJOP, is present in most organisms that have DsrAB and DsrC, and its involvement in energy conservation has been inferred from sequence analysis, but its precise function was so far not determined. Here, we present studies revealing that the DsrMKJOP complex of the sulfate reducer Archaeoglobus fulgidus works as a menadiol:DsrC-trisulfide oxidoreductase. Our results reveal a close interaction between the DsrC-trisulfide and the DsrMKJOP complex and show that electrons from the quinone pool reduce consecutively the DsrM hemes b, the DsrK noncubane [4Fe-4S]3+/2+ catalytic center, and finally the DsrC-trisulfide with concomitant release of sulfide. These results clarify the role of this widespread respiratory membrane complex and indicate that DsrMKJOP will provide the missing link to energy conservation by generating a proton motive force across the membrane in the last step of dissimilatory sulfate reduction. Significance Statement Dissimilatory sulfate reduction (DSR) is a vital microbial process in anoxic environments, namely in sulfate-rich marine sediments that harbor a vast microbial ecosystem. DSR drives the global biogeochemical sulfur cycle and is crucial in remineralization of organic matter on the seafloor. It also has huge environmental impact by preventing release of the greenhouse gas methane from these sediments, through its oxidation coupled to sulfate reduction. Despite its high ecological importance, it is still not clear how microorganisms derive energy to grow through DSR. Here, we disclose the physiological function of a widespread membrane complex in DSR, showing it acts as the terminal reductase in the respiratory chain and providing important insights into how sulfate/sulfite reduction is linked to energy conservation.
Tracking the popularity and outcomes of all bioRxiv preprints

Researchers in the life sciences are posting work to preprint servers at an unprecedented and increasing rate, sharing papers online before (or instead of) publication in peer-reviewed journals. Though the increasing acceptance of preprints is driving policy changes for journals and funders, there is little information about their usage. Here, we collected and analyzed data on all 37,648 preprints uploaded to bioRxiv.org, the largest biology-focused preprint server, in its first five years. We find preprints are being downloaded more than ever before (1.1 million tallied in October 2018 alone) and that the rate of preprints being posted has increased to a recent high of 2,100 per month. We also find that two-thirds of preprints posted before 2017 were later published in peer-reviewed journals, and find a relationship between journal impact factor and preprint downloads. Lastly, we developed Rxivist.org, a web application providing multiple ways of interacting with preprint metadata.
Radio frequency (Rf) energy harvesting using metamaterial structure for antenna/rectenna communication network: A review

Starting from the year 2000, metamaterial structure has been one of the favorite techniques used by several researchers to improve the performance of many radio frequency (RF) device designs, especially in the microwave range area. Wireless charging technologies that have emerged are also one of the highlighted discussions among users, fabricators and researchers. This paper presents a literature review of radio frequency energy harvesting, using a split ring resonator (SRR) and other metamaterial structure in antenna network applications. The objective of this paper is to define and compare the several performances such as the technique used, the material of the substrate, dimension, return loss and the resonant frequency of the antenna. The split ring resonator is an interesting metamaterial structure, that is applied in several researcher’s work compared with other metamaterial structure such as electronic band gap (EBG), photonic band gap (PBG), and artificial magnetic conductor (AMC). This structure has the capability to improve the performance of the resonant frequency, minimizing the size and improving the return loss of the design, while sometimes creating a filter notch to the design. SRR structure is a good candidate for energy harvesting because it can increase the conversion efficiency.
Monitoring Agricultural Productivity for Sustainable Production and R&D planning-G20 Insights

Argentina’s G20 presidency has emphasized the needs to improve soil management and increase agricultural productivity in a sustainable way to achieve an inclusive and resilient food future. While increases in agricultural productivity improve economic welfare and can help address food security problems by benefiting both consumers and producers simultaneously, it has to address the depletion of scarce natural resources.
Damped harmonic oscillator and bosonic string theory through noncommutativity

Some features of noncommutativity are investigated in this work. A noncommutative (NC) versions for the 2D harmonic oscillator and scalar field theory are obtained via the Noncommutative Mapping and fourfold discussion are presented: first, the Lagrangian of the damped harmonic oscillator (DHO), which was an original explanation for the dissipative process presenting in the atomic nuclei collision, is reobtained through noncommutativity. Here, we show that the NC parameter plays the role of the viscous damping coefficient; second, the NC harmonic oscillator is mapped into the bosonic string theory in the light cone frame, which appears as a bosonic string theory attached to a D3-brane; third, we discuss the connection between DHO and bosonic string attached to a D3-brane; fourth, the NC scalar field is indicating into 2D-NC harmonic oscillator.
The erosion of colonial trade linkages after independence I

Most independent nations today were part of empires in 1945. Using bilateral trade data from 1948 to 2006, we examine the effect of independence on post-colonial trade. While there is little short-run effect on trade, after three decades trade with the metropole (colonizer) shrinks by more than 60%. Hostile separations lead to large, immediate reductions in trade. We also find that trade between former colonies of the same empire erodes as much as trade with the metropole, whereas trade with third countries decreases about 20%. The gradual trade deterioration following independence suggests the depreciation of some form of trading capital. JEL classification: F15
Confidence and Power of the Sharpe Ratio under Multiple Testing

Most papers in the financial literature estimate the p-value associated with an investment strategy, without reporting the power of the test used to make that discovery. In this paper we provide analytic estimates to Type I and Type II errors for the Sharpe ratios of investments, and derive their familywise counterparts. These estimates allow researchers to carefully design experiments with high confidence and power.
POSTRADICAL PROSTATECTOMY IRRADIATION IN PROSTATE CANCER

The ACR Committee on Appropriateness Criteria and its expert panels have developed criteria for determining appropriate imaging examinations for diagnosis and treatment of specified medical condition(s). These criteria are intended to guide radiologists, radiation oncologists and referring physicians in making decisions regarding radiologic imaging and treatment. Generally, the complexity and severity of a patient’s clinical condition should dictate the selection of appropriate imaging procedures or treatments. Only those examinations generally used for evaluation of the patient’s condition are ranked. Other imaging studies necessary to evaluate other co-existent diseases or other medical consequences of this condition are not considered in this document. The availability of equipment or personnel may influence the selection of appropriate imaging procedures or treatments. Imaging techniques classified as investigational by the FDA have not been considered in developing these criteria; however, study of new equipment and applications should be encouraged. The ultimate decision regarding the appropriateness of any specific radiologic examination or treatment must be made by the referring physician and radiologist in light of all the circumstances presented in an individual examination.
Antisocial Personality Disorder: A Mentalizing Framework

Antisocial personality disorder (ASPD) is a common condition with major public health implications. Yet effective treatment remains elusive. In this paper the major descriptive symptoms of ASPD are considered using a mentalizing framework. Mentalizing is the implicit or explicit perception or interpretation of the actions of others or oneself as intentional, that is, mediated by mental states or mental processes. It is considered as four intersecting dimensions: automatic/controlled or implicit/explicit; internally/externally based; self/other orientated; and cognitive/affective process. People with ASPD show problems with self/other mentalizing particularly in terms of empathic understanding of others. Their focus is biased toward external mentalizing with little regard for the internal mentalizing of others. The translation of this understanding into a clinical treatment program is discussed. The program is based on the current, evidence-based, mentalization-based treatment (MBT) for borderline personal.
Efficient frequency response computation for low-order modelling of spatially distributed systems

ABSTRACT Motivated by the challenges of designing feedback controllers for spatially distributed systems, we present an efficient approach to obtaining the frequency response of such systems, from which low-order models can be identified. This is achieved by combining the frequency responses of constituent lower-order subsystems in a way that exploits the interconnectivity arising from spatial discretisation. This approach extends to the singular subsystems that arise upon spatial discretisation of systems governed by PDAEs, with fluid flows being a prime example. The main result of this paper is a proof that the computational complexity of forming the overall frequency response is minimised if the subsystems are merged in a particular fashion. Doing so reduces the complexity by several orders of magnitude; a result demonstrated upon the numerical example of a spatially discretised wave-diffusion equation. By avoiding the construction, storage, or manipulation of large-scale system matrices, this modelling approach is well conditioned and computationally tractable for spatially distributed systems consisting of enormous numbers of subsystems, therefore bypassing many of the problems with conventional model reduction techniques.
REVISTA ENIAC PESQUISA

The purpose of this study was to analyze the Supersignals of the Technical Analysis, seeking to elucidate the process of buying and selling assets. Through the analysis, the positive and negative aspects of the Supersignals use were investigated, since it is a little explored technique, because it is very recent. The research is carried out through a bibliographical review that retakes concepts such as Dow Theory, Efficient Market Hypothesis and Technical Analysis. In this direction, the present study is justified by its contribution to future research 1 Autor para correspondência: Universidade Federal de Uberlândia (UFU): Av.

We concluded that the Supersignals of the technical analysis can function efficiently, however, they do not represent a completely effective index if applied alone.
Impact of Pre-Pregnancy Hemoglobin Level on the Association Between Pre-Pregnancy Body Mass Index and Gestational Diabetes Mellitus: A Retrospective Cohort Study in a Single Center in China

Aim: To assess the impact of maternal pre-pregnancy body mass index (BMI) on gestational diabetes mellitus (GDM) based on different pre-pregnancy hemoglobin levels. Methods: This retrospective cohort study included 1289 pregnant women between June 2020 and January 2022. Clinical data were collected by reviewing their medical and antepartum screening records between 24 and 28 gestational weeks, including pre-pregnancy BMI and pre-pregnancy hemoglobin (Hb) levels. The diagnosis of GDM mainly depended on oral glucose tolerance test (OGTT) during 24–28 weeks. Restricted cubic spline (RCS) was used to investigate the association between the pre-pregnancy Hb level and the risk of GDM. Univariate and multivariate logistic regression analyses were applied to evaluate the relative risk of GDM. Results: Of the 1289 included pregnant women, 187 (14.5%) women were diagnosed with GDM in this study. The pre-pregnancy Hb level was significantly associated with GDM risk, and the pre-pregnancy Hb level of 123 g/L was identified as the threshold to stratify and assess the association between the GDM risk and the pre-pregnancy BMI. For women with a pre-pregnancy Hb level ≥123 g/L, the pre-pregnancy BMI showed a significant association with GDM risk, and the estimated incidence rate of GDM was 7.7%, 14.8%, 36.3% and 44% for underweight, normal-weight, overweight and obese pregnant women, respectively. After adjusting for potential influencing factors of GDM, the respective relative risk was 1.0 (reference), 2.04 (95% CI 0.84, 4.99), 7.06 (2.66, 18.61), and 10.77 (2.85, 40.63) (P for trend < 0.001). Conclusion: In pregnant women with a pre-pregnancy Hb level ≥123 g/L, pre-pregnancy BMI showed a more significant association with GDM risk as compared with those with a pre-pregnancy Hb level <123 g/L.
Cost-effectiveness analysis of HIV treatment in the clinical practice of a public hospital in northern Italy

Patients methods: The incremental cost-effectiveness analysis was completed by means of a Markov model. Through a decision-analytic approach, this enabled us to compare the studied antiretroviral regimens. The model considered a population of adult HIV subjects who received HAART therapy for the first time according to clinical practice in the Infectious Diseases Department of “L. Sacco” Hospital, Milan. Data were investigated from the standpoint of the Lombardy Regional Health Service. We considered the following outcome measures: quality-adjusted life-years (QALYs), and direct health costs calculated for the years 2008 and 2009. The time horizon adopted in the model was 2 years. Results: The model revealed that, in terms of cost per gained QALY, the tenofovir disoproxil fumarate + emtricitabine + efavirenz (TDF + FTC + EFV) once-a-day treatment strategy seems to be the most cost-effective therapeutic choice ( € 34,965); the incremental cost-effectiveness ratio (ICER) values for the remaining strategies ranged from € 53,000 to around € 62,000 per QALY. The validity of the base case scenario was then confirmed by means of a sensitivity analysis on the main variables. Conclusion: The TDF + FTC + EFV treatment strategy (TDF/FTC + EFV fixed-dose combination then switched to single-tablet regimen [STR]) in this setting is the most cost-effective treatment strategy compared with the other therapeutic regimens. The ICER value for the TDF + FTC + EFV once-a-day then switched to STR treatment was lower than the internationally generally accepted threshold value of € 50,000. The developed model is a tool for policy makers and health care professionals for creating short- and long-term cost projections, with the aim of assessing their impact on the available budgets for HIV patients.
Ray Tracing Dynamic Scenes Using Multiple Kd-trees

With faster hardware and algorithmic improvements, real-time ray tracing is finally within reach. A variety of different data structures have been developed for ray tracing over the past decades. These spatial data structures crucial for fast ray tracing must be rebuilt or updated as the scene changes, and this can become a bottle-neck for the speed of ray tracing. In this paper, a novel algorithm is proposed to improve the rendering speed for static and moving objects by build kd-trees respectively, i.e., we construct multiple kd-trees. This building method allows for ray tracing animations without rebuilding the spatial index structures for the whole scene, just for dynamic objects. We implement the proposed algorithm for ray tracing dynamic scene on CPU+GPU platform, resulting in frame rates of 3~5 fps for 1024*1024 images, which improves rendering speed of dynamic scenes significantly.
A Model of Fuzzy Normal Distribution

Nowadays fuzzy concepts are frequently used as statistical parameters, while the traditional normal distribution can only accept determinate variable. In order to design a practical model for fuzzy statistic events, this paper combines the fuzzy number, like “may-occur”, “very-likely-occur”, “rarely-occur”, to optimize the normal distribution probability density function, to provide a significant method in statistics.
INTERPERSONAL RELATIONS AND GROUP PROCESSES The Jury and Abjury of My Peers: The Self in Face and Dignity Cultures

The self is defined and judged differently by people from face and dignity cultures (in this case, Hong Kong and the United States, respectively). Across 3 experiments, people from a face culture absorbed the judgments of other people into their private self-definitions. Particularly important for people from a face culture are public representations—knowledge that is shared and known to be shared about someone. In contrast, people from a dignity culture try to preserve the sovereign self by not letting others define them. In the 3 experiments, dignity culture participants showed a studied indifference to the judgments of their peers, ignoring peers’ assessments—whether those assessments were public or private, were positive or negative, or were made by qualified peers or unqualified peers. Ways that the self is “knotted” up with social judgments and cultural imperatives are discussed.
Analysis of free image-based modelling systems applied to support topographic measurements

The image-based modelling systems create 3D models of objects using a set of overlapping photographs. Several applications are available that do not require a user expert or expensive equipment. In this paper, four free systems were applied in two cases: ReMake, which is a freemium software, CMP Web Service and Arc 3D, which are free web services, and Visual SfM, which is a free software. The purpose of this study is to evaluate the applications that support topographical measurements and to assess the potential for their use in accurate modelling. The results show that these systems can be an auxiliary technique for surveyors and can provide an advantage in some cases.
