Dynamic Incentive Design for Participation in Direct Load Scheduling Programs

Interruptible Load (IL) programs have long been an accepted measure to intelligently and reliably shed demand in case of contingencies in the power grid. However, the emerging market for Electric Vehicles (EV) and the notion of providing non-emergency ancillary services through the demand side have sparked new interest in designing direct load scheduling programs that manage the consumption of appliances on a day-to-day basis. In this paper, we define a mechanism for a Load Serving Entity (LSE) to strategically compensate customers that allow the LSE to directly schedule their consumption, every time they want to use an eligible appliance. We study how the LSE can compute such incentives by forecasting its profits from shifting the load of recruited appliances to hours when electricity is cheap, or by providing ancillary services, such as regulation and load following. To make the problem scalable and tractable we use a novel clustering approach to describe appliance load and laxity. In our model, customers choose to participate in this program strategically, in response to incentives posted by the LSE in publicly available menus. Since 1) appliances have different levels of demand flexibility; and 2) demand flexibility has a time-varying value to the LSE due to changing wholesale prices, we allow the incentives to vary dynamically with time and appliance cluster. We study the economic effects of the implementation of such program on a population of EVs, using real-world data for vehicle arrival and charge patterns.
Effect of early or delayed insertion of tympanostomy tubes for persistent otitis media on developmental outcomes at the age of three years

Background A main indication for the insertion of tympanostomy tubes in infants and young children is persistent otitis media with effusion, reflecting concern that this condition may cause lasting impairments of speech, language, cognitive, and psychosocial development. However, evidence of such relations is inconclusive, and evidence is lacking that the insertion of tympanostomy tubes prevents developmental impairment. Methods We enrolled 6350 healthy infants from 2 to 61 days of age and evaluated them regularly for middle-ear effusion. Before the age of three years 429 children with persistent effusion were randomly assigned to have tympanostomy tubes inserted either as soon as possible or up to nine months later if effusion persisted. In 402 of these children we assessed speech, language, cognition, and psychosocial development at the age of three years. Results By the age of three years, 169 children in the early-treatment group (82 percent) and 66 children in the late-treatment group (34 percent) ha...
Principles and Parameters: a coding theory perspective

We propose an approach to Longobardi’s parametric comparison method (PCM) via the theory of error-correcting codes. One associates to a collection of languages to be analyzed with the PCM a binary (or ternary) code with one code words for each language in the family and each word consisting of the binary values of the syntactic parameters of the language, with the ternary case allowing for an additional parameter state that takes into account phenomena of entailment of parameters. The code parameters of the resulting code can be compared with some classical bounds in coding theory: the asymptotic bound, the Gilbert–Varshamov bound, etc. The position of the code parameters with respect to some of these bounds provides quantitative information on the variability of syntactic parameters within and across historical-linguistic families. While computations carried out for languages belonging to the same family yield codes below the GV curve, comparisons across different historical families can give examples of isolated codes lying above the asymptotic bound.
Global Optimization for Image Restoration in Optical/IR Interferometry

Many image reconstruction algorithms have been proposed to cope with optical/IR interferometric data. A first difficulty is to deal with the sparsity of the data and the uneven u-v coverage. This is usually overcome by imposing a priori constraints to the sought image. The reconstruction then amounts to solving an optimization problem where fidelity to the data and to the priors must both be satisfied to a chosen level. Due to the type of interferometric measurements, the image restored by the current algorithms depends on some initial guess and on the optimization strategy. Even though the resulting image is often satisfactory, there are no guarantees that the best image is obtained given the data and the constraints. This is a strong defect which may badly impact the interpretation of interferometric observations by astronomers. In this paper, we consider using stochastic methods such as simulated annealing to solve for the problem of image reconstruction with sparse Fourier amplitudes and unknown Fourier phases. This preliminary study is a first step toward image reconstruction with partial Fourier phase information.
Do Economic Conditions Drive DIP Lending?: Evidence from the Financial Crisis

A firm that seeks refuge in Chapter 11 typically requires financing for its continuing operations in bankruptcy. Because such financing is often hard to find, the Bankruptcy Code authorizes debtors to offer sweeteners to debtor-in-possession (DIP) lenders. These inducements can be highly effective in attracting financing. But because these sweeteners are thought to come at the expense of other stakeholders, the Code requires a showing that no less generous a package would have been sufficient to obtain the loan. Anecdotal evidence suggests that the use of certain controversial inducements skyrocketed during the Financial Crisis, leading critics to question whether DIP lenders were abusing their power. Defenders of DIP lenders, however, have responded that the contract terms in DIP loans simply reflect economic conditions: When credit is tight, as it was in recent years because of the Financial Crisis, of course more sweeteners are needed to induce lending.In this Article, we examine the relationship between economic conditions and the terms of DIP loans. Using a hand-collected dataset reflecting contractual detail in DIP loans, we study changes in DIP loan terms during the Crisis. As one might expect, we find that ordinary loan provisions like pricing and reporting covenants are sensitive to economic conditions. But we also find that so-called "extraordinary provisions," often justified as necessary to induce DIP lending, have no statistically meaningful relationship with economic conditions. Our findings have important implications for bankruptcy judges struggling to evaluate whether the sweeteners extracted by DIP lenders are really necessary to induce lending.

Understanding physical activity lapses among women: responses to lapses and the potential buffering effect of social support.

Many women fail to meet recommended levels of physical activity (PA). Limited research has examined women’s barriers to PA adoption during attempts to increase PA—in particular, how often they experience PA lapses (i.e., failure to meet PA goals), their cognitive–affective responses to lapses, and the role of social support in preventing or responding to lapses. The present study assessed weekly variability in PA lapses, cognitive–affective responses to lapses, and social support related to PA among women participating in a partner-based PA program (n = 20). Multilevel modeling showed that greater PA self-efficacy and more frequent partner communication predicted fewer lapses during the concurrent or subsequent week (ps < 0.02). Interestingly, greater self-forgiveness for lapsing also predicted more lapses the subsequent week (p = 0.04), though greater perceived partner support appeared to buffer the negative effect of self-forgiveness on future lapses (p = 0.04). These findings demonstrate the importance of cognitive–affective responses to PA lapses for future PA, as well as the potential benefit of social support for preventing PA lapses among women.

Multi-exciton emission from solitary dopant states of carbon nanotubes

By separating the photons from slow and fast decays of single and multi-exciton states in a time gated 2nd order photon correlation experiment, we show that solitary oxygen dopant states of single-walled carbon nanotubes (SWCNTs) allow emission of photon pairs with efficiencies as high as 44% of single exciton emission. Our pump dependent time resolved photoluminescence (PL) studies further reveal diffusion-limited exciton–exciton annihilation as the key process that limits the emission of multi-excitons at high pump fluences. We further postulate that creation of additional permanent exciton quenching sites occurring under intense laser irradiation leads to permanent PL quenching. With this work, we bring out multi-excitonic processes of solitary dopant states as a new area to be explored for potential applications in lasing and entangled photon generation.
Balanced-budget rules and risk-sharing in a fiscal union

Abstract This paper addresses the following question: What are the implications of the asymmetry of balanced-budget rules for interregional risk sharing in a fiscal union? We investigate our research question in a two-region, open economy DSGE model that is augmented with the public-sector features of a federal state. The analysis demonstrates that the asymmetry of balanced-budget rules is detrimental for the risk sharing in the union. The degree of risk sharing is a function of the public good productivity, specification of the technology process, and distribution of productivity shocks in the fiscal union.
Acute Kidney Replacement Therapy in Children

Choice of dialysis modality and prescription in children requires careful multidisciplinary coordination and must be tailored to the individual patient and clinical situation. Peritoneal dialysis has the advantages of simplicity and no need for vascular access and systemic anticoagulation. Patients with severe abdominal pathology may, however, be ineligible as a useable abdomen and functioning peritoneal membrane are mandatory. Peritoneal dialysis may be a poor choice if rapid correction of metabolic/electrolyte state is required. Extracorporeal hemodialysis and hemofiltration techniques and systems are well established even for the smallest children and have the advantage of high efficiency and permitting quick correction of metabolic and fluid imbalance. Intermittent hemodialysis may be poorly tolerated, however, by the critically ill patient in whom continuous therapies may be preferable.
Frequency Measurements from the Microwave to the Visible, the Speed of Light, and the Redefinition of the Meter

The techniques of laser frequency measurement, especially those leading to the measurements of the frequency of visible light, will be described. The use of these techniques has led to much higher accuracy in spectral measurements, a hundred-fold increase in the accuracy of the value of the speed of light, and to a proposed redefinition of the meter, fixing the value of the speed of light. The use of stabilized lasers in these measurements, some of the characteristics of the metal-insulator-metal diode used in high speed detection, and the realization of the meter with the proposed new definition will also be described.
Complex Neural Integration and Identified Interneurons in the Locust Brain

In 1971, one of us (Rowell, 197la) published an extensive literature review concerned with the analysis of responses recorded extracellularly from certain movement-detecting visual interneurons (INs) contained in the ventral thoracic nerve cord of grasshoppers and crickets. These units attracted attention because they are the most conspicuous (~ 3 mV) of the units which can be recorded with extracellular hook electrodes from the whole thoracic cord. They were characterized (Rowell, 197la) and called the descending movement detectors (DMDs). They fall into two classes depending on whether they are excited by movement in the receptive field of the eye ipsilateral or contralateral to the nerve cord projection: DIMDs or DCMDs. Prior to 1971, the DMD neurons in both crickets and grasshoppers were used in studies on perception of movement and visual acuity (Built and Catton, 1954, 1962, 1966, 1969; Palka, 1965), color sensitivity (Suga and Katsuki, 1962), and light and dark adaptation (Burtt et al.,1963, Cosens, 1966). These studies were not directed at determining either the function in behavior or the origin, in neural terms, of the specific response characteristics. The DMDs were also studied in their own right, and by 1971 a body of work had accumulated describing their specific response characteristics (Palka, 1967a,b, 1969; Rowell and Horn, 1967, 1968; Horn and Rowell, 1968; Rowell, 197la). The ease of extracellular recording still makes them an attractive and convenient assay for general properties of the visual system (Northrop, 1974; Palka and Pinter, 1975). Consideration of their role in behavior was introduced (Rowell, 197la) and extended, for the DCMD, by studies in freely moving animals (Rowell, 197lb,c).
The Role of Depth and 1/ f Dynamics in Perceiving Reversible Figures

When confronted with a reversible figure, such as the Necker Cube, viewers experience a spontaneously changing percept. We assess the dynamic of how the human visual system resolves perceptual ambiguity in stimuli that offer multiple interpretations. Subjects observed the Necker cube for one of three viewing durations during which they pressed a key each time they perceived a change in the orientation of the cube. Manipulations of binocular disparity served as a parameter to control perceptual stability. Low-depth conditions yielded more perceptual reversals than high-depth conditions. A Fourier analysis performed on the time series of reversals show 1/f (pink) noise was evident in their power spectra. These results together with theoretical models of complex systems (e.g., Bak, Tang, & Wiesenfeld, 1987) suggest that depth information may guide our perceptual system into a self-organized state to assist us in resolving ambiguous information. Moreover, slopes of the spectra were steeper in high-depth and brief viewing conditions, suggesting that the visual system relies more on previous perceptual states and filters more white noise in these conditions.
Immunochemical characterization of a human antibody to factor XIII.

Antibodies to factor XIII have not been previously characterized in detail. An acquired inhibitor to factor XIII, which developed in a patient following thrombectomy for a femoral artery occlusion, has been characterized as to immunoglobulin composition. A highly sensitive monodansylcadaverine assay for factor XIII was employed. The inhibitor was completely neutralized by antisera specific for the γG class, γG1 subclass, and λ light-chain type. Antisera to γG2, γG3, γG4, γA, γM, γD, γE, and k light-chains had no detectable effect. Preparative zone electrophoresis revealed the inhibitor to be in the cathodal portion of the gamma peak, with moderately restricted electrophoretic mobility. The factor XIII inhibitor is thus characterized as a γGl, λ immunoglobulin and resembles other human antibodies to clotting factors that are restricted in immunoglobulin composition.
Augmentation of Power Quality of Grid-Connected Wind Generator by Fuzzy Logic Controlled TSC

This paper proposes a fuzzy logic controlled thyristor switched capacitor (TSC) to improve the power quality of a hybrid network system consisting of one wind generator and two conventional synchronous generators. The performance of the proposed method is compared with that of the Proportional-Integral-Derivative (PID) controlled TSC. The effectiveness of the proposed method is evaluated by considering both balanced and unbalanced permanent faults in the system. Moreover, in order to demonstrate the effectiveness of the proposed approach, the voltage index associated with the point of common coupling (PCC) of the power network has been used. In addition, the power quality in terms of harmonic distortion has been evaluated at the PCC for both synchronous generators and wind generator. Simulations have been performed by using the Matlab/Simulink software. From the simulation results, it is clear that the proposed fuzzy logic controlled TSC method is effective in improving the power quality of the hybrid network system. In addition, the proposed fuzzy logic controlled TSC performs better than the conventional PID controlled TSC.
Depositionally-Induced Magnetic Frequency Variations of a Sandstone Facies from the Copper Harbor Conglomerate of the North American, Mid-Continent Rift at Union Bay, Michigan

Precambrian sandstones were investigated to determine whether deep-time, fluvial red-beds can maintain magnetic variations related to deposition. Using an easily accessible site on Earth, it is possible to define methods that benefit future studies related to magnetic variations as linked to conditions of formation. The study utilized environmental magnetism and cyclostratigraphic techniques to determine magnetic characteristics and susceptibility variation frequencies. Magnetite and hematite were inferred from laboratory measurements and the magnetic fabric agreed with previous paleocurrent observations, suggestive that susceptibility correlates with deposition. Hematite concentration controlled susceptibility: high-susceptibility corresponded with large grain-sizes and cross-bedding, while low-susceptibility was attributed to small grain-sizes and erosional or color boundaries. A statistically-significant, cyclic, susceptibility signal was observed from the stratigraphy, suggesting that susceptibility variations may arise from climatically-induced variations in depositional or post-depositional processes. The observed frequency also supports the capacity for fluvial red-bed deposits to maintain depositional characteristics original to formational processes.
Are Mediterranean Marine Protected Areas sheltered from plastic pollution

Abstract Comparisons of six selected Mediterranean MPAs were conducted to find similarities and site-specific differences in coastline fluxes and sources of plastic marine litter. Output from the recently developed 2D Lagrangian model for the Mediterranean was post-processed to study (1) the National Park of ses Salines d’Eivissa i Formentera, (2) Nature Reserve of Bouches de Bonifacio, (3) North-East Malta MPA, (4) Specially Protected Area of Porto Cesareo, (5) Community Importance Site of Torre Guaceto, and (6) Ethniko Thalassio Parko Alonnisou Voreion Sporadon. Model coastline fluxes of plastic ranged from 0.4 to3.6 kg (km day)−1, which is relatively low compared to the average flux of 6.2 ± 0.8 kg (km day)−1 calculated over the Mediterranean 2013–2017. Shipping was identified as a major source of plastic litter in all MPAs studied, contributing 55%–88% of total plastic. Site-specific rankings of the top 5 land-based plastic sources revealed that sea surface kinematics control plastic drift.
A General Control Switching Framework for Supervisory Control of Discrete Event Systems

We present a supervisory control architecture with control redundancy. We assume an adaptive architecture for the problem of switching from one control module to another when sensors used for observing events in the plant fail or become unavailable. It is assumed that there is an actual controller and a number of virtual controllers. The actual controller is in real feedback loop with the plant whereas the virtual ones are in virtual feedback such that the coupled behaviour of any of these control modules with plant conforms to what is called normality criterion in the context of partial observation. Every time that a failure occurs and the environment changes, the actual controller is replaced by one of these virtual ones according to specified optimality criteria.
Variation in patterns of health care before suicide: a population case-control study

Abstract Background The United States has experienced a significant rise in suicide. As decision makers identify how to address this national concern, healthcare systems have been identified as an optimal location for prevention. Objective To compare variation in patterns of healthcare use, by health setting, between individuals who died by suicide and the general population. Design Case-Control Study. Setting Eight healthcare systems across the United States. Participants 2674 individuals who died by suicide between 2000 and 2013 along with 267,400 individuals matched on time-period of health plan membership and health system affiliation. Measurements Healthcare use in the emergency room, inpatient hospital, primary care, and outpatient specialty setting measured using electronic health record data during the 7-, 30-, 60-, 90-, 180-, and 365-day time periods before suicide and matched index date for controls. Results Healthcare use was more common across all healthcare settings for individuals who died by suicide. Nearly 30% of individuals had a healthcare visit in the 7-days before suicide (6.5% emergency, 16.3% outpatient specialty, and 9.5% primary care), over half within 30 days, and >90% within 365 days. Those who died by suicide averaged 16.7 healthcare visits during the year. The relative risk of suicide was greatest for individuals who received care in the inpatient setting (aOR = 6.23). There was both a large relative risk (aOR = 3.08) and absolute utilization rate (43.8%) in the emergency room before suicide. Limitations Participant race/ethnicity was not available. The sample did not include uninsured individuals. Conclusions This study provides important data about how care utilization differs for those who die by suicide compared to the general population and can inform decision makers on targeting of suicide prevention activities within health systems.
Integrating Co-Evolutionary Information in Monte Carlo Based Method for Proteins Trajectory Simulation

The conformational space of proteins is complex and high dimensional, which makes its analysis a highly challenging task. Understanding the structure and dynamics of proteins is essential in order to understand their function. Intermediate structures are often hard to capture experimentally, as well as conformational trajectory due to rapid dynamics. How a protein molecule acquires a specific structure remains an open problem, as well as how proteins transition from one conformation to another as a result of a shift in conditions. In this work, we combine evolutionary information obtained from proteins' sequence and structure with conformational search to elucidate the conformational trajectory of proteins. In a previous work we used rigidity analysis to reduce the search space of proteins undergoing large-scale conformational changes. We advance in this work by incorporating the backbone + C-beta resolution for all of the molecules in the experiments and resort to a new way to limit the search space by identifying the co-evolving residues in a molecule. We use a modified version of the Monte Carlo-based tree search algorithm to sample the search space and guide it by expanding the search only in the direction of energetically feasible conformations that are close to the goal structure of the molecule, using perturbation on co-evolving residues as a guide.
The Carnival of Treachery, June–November 1938

Hemingway arrived in New York aboard the Normandie on 30 May 1938.1 It was Memorial Day—an ideal occasion to inform a reporter from the New York Times about his exhausting coverage of Spain’s Civil War on countless fronts. He did not mention the four International Brigade stowaways found aboard the Normandie, whom the Times saw fit to label “Loyalist Army Deserters.”2 Instead, Ernest assured readers of the Times that the Loyalists still had “a good chance of winning.” There were divisions among the international forces assisting Franco; moreover, Franco was short of troops. Ernest predicted that “the war would drag on for some time,” and though he was now returning to Key West in order to write some new short stories and start on a novel, he would return to Spain “if things got hot.”
Importance of Facial Plastic Surgery Education in Residency: A Resident Survey

Introduction Facial plastic and reconstructive surgery (FPRS) is a key part of the curriculum for otolaryngology residents. It is important to gain an understanding of the breadth of exposure and level of competence residents feel with these concepts during their residency. Objective To determine the level of FPRS exposure and training otolaryngology residents receive during their residency. Methods A survey was emailed to all Accreditation Council for Graduate Medical Education (ACGME) accredited otolaryngology residents. The survey aimed to find the level of exposure to FPRS procedures otolaryngology residents get and how confident they feel with their training in cosmetic FPRS. Results A total of 213 residents responded to the survey for an overall response rate of 13.4%. There was an even mixture of residents from all postgraduate year (PGY) levels, with 58% of respondents being male. Almost all (98%) of the residents felt FPRS was important to otolaryngology residency training. Exposure to procedures varied with 57% performing or assisting with cosmetic minor procedures, 81% performing or assisting with cosmetic major procedures, and 93% performing or assisting with reconstructive procedures. Only 49% of residents felt their programs either very or somewhat adequately prepared them in cosmetic facial plastic surgery. Conclusion There was a wide variability in the FPRS procedure exposure. Most residents felt procedures were a vital part of otolaryngology residency training, but not all were able to participate in them. Only half of the residents felt well-prepared in cosmetic procedures.

104. REDUCING CENTRAL LINE ASSOCIATED BLOODSTREAM INFECTIONS BY OPTIMIZING BUNDLE COMPLIANCE

Background Central line associated bloodstream infections (CLABSIs) are a significant cause of morbidity and mortality in pediatric patients. They are associated with a mean attributable cost of $55,646 and a mean attributable length of stay of 19 days. Previous studies have addressed this issue through bundle compliance, which includes the daily discussion of line necessity. Our baseline frequency of daily line discussion was 20.6%, and our CLABSI rate at the start of this project was 1.06 per 1000 catheter days. Aim Statement We planned to double the frequency of central line discussions in pediatric patients admitted to the medical/surgical units over a 1-year period. Interventions We used the model for improvement and PDSA cycles to implement change. Individual PDSA cycles tested our interventions and guided subsequent change cycles. We first implemented provider rounding lists with prompts to discuss central lines. We then developed a multidisciplinary team to drive change. This inspired the adaptation of a safety cross auditing tool, as well as the implementation of provider education sessions. Measures The frequency that central lines were addressed during rounds was the primary outcome measure. Provider comfort level with central lines was a secondary measure, and disturbance of workflow was the balancing measure. Results The initial implementation of new rounding lists did not generate significant change. The frequency that central lines were addressed increased from a mean of 28% to 50% after creating a multidisciplinary team (month 5). The mean again increased from 50% to 74% after implementing a safety cross tool and education sessions (month 9). Provider comfort level with central lines increased from a baseline of 2.43 to 2.93 on a 1 to 4 Likert (P Conclusions and Next Steps The daily discussion of central line necessity, as well as provider comfort level with central lines, demonstrated meaningful changes with our interventions. These are crucial components of the central line bundle and played a key role in the global aim of decreasing CLABSI rates. Throughout the duration of this project, the CLABSI rates in our institution decreased from 1.06 per 1000 catheter days to 0.68 per 1000 catheter days, a 36% reduction. In the future, resident CLABSI champions will be identified to make changes from this project sustainable.

The Safety and Efficacy of Transcatheter Pulmonary Valve Replacement Combined with Electrophysiology Procedures

The objective of this study was to evaluate the safety and efficacy of combining transcatheter pulmonary valve replacement (TPVR) and electrophysiology (EP) procedures. A retrospective review was undertaken to identify TPVR and EP procedures that were concomitantly performed in the cardiac catheterization laboratory at University of Iowa Stead Family Children’s Hospital from January 2011 to October 2019. Procedural and follow-up data were compared between patients who underwent TPVR and EP procedures in the same setting to those who received TPVR or EP procedure separately and that were similar in age and cardiac anatomy. A total of 8 patients underwent combined TPVR and EP procedures. One patient was excluded due to lack of adequate control, leaving seven study subjects (57% female; median age at time of procedure 16 years). The median follow-up time was 11.5 months (range 2–36 months). Patients who received combined TPVR and EP had shorter recovery times (combined: median 18.9 h; IQR 18.35–19.5 vs separate: median 27.98 h; IQR 21.42–39.25; p-value 0.031), shorter hospital length of stay (combined: median 27.5 h; IQR 26.47–31.4 vs separate: median 38.4 h; IQR 33.42–51.50; p-value 0.016), and a 51% reduction in total hospital charges (combined: median $171,640; IQR 135.43–219.22 vs separate: median $333,560 IQR 263.20–400.98; p-value 0.016). There were no significant differences in radiation dose or procedure time between the combined and control groups. The median radiation time for those who had the combination procedure was 30.5 min [IQR 29.6–47.9], and the median dose area product was 215 mGy [IQR 158–935]. In conclusion, combining TPVR and EP procedures is feasible, safe, and economically advantageous.
Bosonization of QED3 with an induced Chern-Simons term

Abstract We extend the bosonization of (2 + 1)-dimensional QED with one fermionic flavor performed previously to the case of QED with an induced Chern-Simons term. The coefficient of this term is quantized: e 2 n/8π, n e Z . The fermion operators are constructed in terms of the bosonic fields A i and E i . The construction is similar to that in the n = 0 case. The resulting bosonic theory is Lorentz invariant in the continuum limit and has Maxwell's equations as its equations of motion. The algebra of bilinears exhibits nontrivial operational mixing with lower dimensional operators, which is absent for n = 0.

1,4,5,8-Naphthalenetetracarboxylic dianhydride grafted phthalocyanine macromolecules as an anode material for lithium ion batteries

For solving the problems of high solubility in electrolytes, poor conductivity and low active site utilization of organic electrode materials, in this work, 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA) grafted nickel phthalocyanine (TNTCDA-NiPc) was synthesized and used as an anode material for lithium ion batteries. As a result, the dispersibility, conductivity and dissolution stability are improved, which is conducive to enhancing the performance of batteries. The initial discharge capacity of the TNTCDA-NiPc electrode is 859.8 mA h g−1 at 2 A g−1 current density, which is much higher than that of the NTCDA electrode (247.4 mA h g−1). After 379 cycles, the discharge capacity of the TNTCDA-NiPc electrode is 1162.9 mA h g−1, and the capacity retention rate is 135.3%, which is 7 times that of the NTCDA electrode. After NTCDA is grafted to the phthalocyanine macrocyclic system, the dissolution of the NTCDA in the electrolyte is reduced, and the conductivity and dispersion of the NTCDA and phthalocyanine ring are also improved, so that more active sites of super lithium intercalation from NTCDA and phthalocyanine rings are exposed, which results in better electrochemical performance. The strategy of grafting small molecular active compounds into macrocyclic conjugated systems used in this work can provide new ideas for the development of high performance organic electrode materials.
Sympatholytic Mechanisms for the Beneficial Cardiovascular Effects of SGLT2 Inhibitors: A Research Hypothesis for Dapagliflozin's Effects in the Adrenal Gland.

Heart failure (HF) remains the leading cause of morbidity and death in the western world, and new therapeutic modalities are urgently needed to improve the lifespan and quality of life of HF patients. The sodium-glucose co-transporter-2 (SGLT2) inhibitors, originally developed and mainly indicated for diabetes mellitus treatment, have been increasingly shown to ameliorate heart disease, and specifically HF, in humans, regardless of diabetes co-existence. Indeed, dapagliflozin has been reported to reduce cardiovascular mortality and hospitalizations in patients with HF and reduced ejection fraction (HFrEF). This SGLT2 inhibitor demonstrates these benefits also in non-diabetic subjects, indicating that dapagliflozin’s efficacy in HF is independent of blood glucose control. Evidence for the effectiveness of various SGLT2 inhibitors in providing cardiovascular benefits irrespective of their effects on blood glucose regulation have spurred the use of these agents in HFrEF treatment and resulted in FDA approvals for cardiovascular indications. The obvious question arising from all these studies is, of course, which molecular/pharmacological mechanisms underlie these cardiovascular benefits of the drugs in diabetics and non-diabetics alike. The fact that SGLT2 is not significantly expressed in cardiac myocytes (SGLT1 appears to be the dominant isoform) adds even greater perplexity to this answer. A variety of mechanisms have been proposed over the past few years and tested in cell and animal models and prominent among those is the potential for sympatholysis, i.e., reduction in sympathetic nervous system activity. The latter is known to be high in HF patients, contributing significantly to the morbidity and mortality of the disease. The present minireview first summarizes the current evidence in the literature supporting the notion that SGLT2 inhibitors, such as dapagliflozin and empagliflozin, exert sympatholysis, and also outlines the main putative underlying mechanisms for these sympatholytic effects. Then, we propose a novel hypothesis, centered on the adrenal medulla, for the sympatholytic effects specifically of dapagliflozin. Adrenal medulla is responsible for the production and secretion of almost the entire amount of circulating epinephrine and of a significant percentage of circulating norepinephrine in the human body. If proven true experimentally, this hypothesis, along with other emerging experimental evidence for sympatholytic effects in neurons, will shed new light on the pharmacological effects that mediate the cardiovascular benefits of SGLT2 inhibitor drugs, independently of their blood glucose-lowering effects.

Transcranial Direct Current Stimulation Post-Stroke Upper Extremity Motor Recovery Studies Exhibit a Dose-Response Relationship.

Abstract Background and purpose Transcranial direct current stimulation (tDCS) has shown mixed results in post-stroke motor recovery, possibly because of tDCS dose differences. The purpose of this meta-analysis was to explore whether the outcome has a dose–response relationship with various dose-related parameters. Methods The literature was searched for double-blind, randomized, sham-controlled clinical trials investigating the role of tDCS (≥5 sessions) in post-stroke motor recovery as measured by the Fugl-Meyer Upper Extremity (FM-UE) scale. Improvements in FM-UE scores were compared between active and sham groups by calculating standardized mean differences (Hedge's g ) to derive a summary effect size. Inverse-variance-weighted linear meta-regression across individual studies was performed between various tDCS parameters and Hedge's g to test for dose–response relationships. Results Eight studies with total of 213 stroke subjects were included. Summary Hedge's g was statistically significant in favor of the active group (Hedge's g = 0.61, p = 0.02) suggesting moderate effect. Specifically, studies that used bihemispheric tDCS montage (Hedge's g = 1.30, p = 0.08) or that recruited chronic stroke patients (Hedge's g = 1.23, p = 0.02) showed large improvements in the active group. A positive dose–response relationship was found with current density (p = 0.017) and charge density (p = 0.004), but not with current amplitude. Moreover, a negative dose–response relationship was found with electrode size (p Conclusions Our meta-analysis and meta-regression results suggest superior motor recovery in the active group when compared to the sham group and dose–response relationships relating to electrode size, charge density and current density. These results need to be confirmed in future dedicated studies.
EXPERIMENTAL INVESTIGATION OF THE GROUND TRANSPORTATION SYSTEMS (GTS) PROJECT FOR HEAVY VEHICLE DRAG REDUCTION

A wind tunnel experimental research program was conducted on a heavily instrumented Ground Transportation System (GTS) vehicle. The GTS baseline model represented a generic 1:8 scale Class-8 van-type tractor trailer geometry. Five base drag reduction add-on devices, instrumented with surface pressure ports, were also tested. These add-on devices included two ogive boattail shapes and three slant geometry devices. Six component force and moment data, surface pressure contours, and wake velocity surveys are presented for each configuration along with qualitative insights gained from flow visualization. This wind tunnel program was designed to complement a parallel research effort in computational fluid dynamics (CFD) which modeled many of these same vehicle geometries. The wind tunnel data are documented and archived in ASCII format on floppy discs and available to researchers interested in further analysis or comparison to other CFD solutions.
Staking our claim for qualitative psychology as science

A science includes both a system of concepts for the classification of phenomena and a set of rules for constructing models of unobservable process by which the phenomena are generated. The phenomena of the human sciences are meaningful and of the natural sciences, meaningless. Correspondingly, there are discursive modes of representation and complementary material representations. Eschewing quantitative representations excludes material phenomena from psychology. This does not mean that all mathematical forms of representation should be excluded: arithmetic is little use; algebra marginal but geometrical/structural mathematics is of value. However, grammar (in Wittgenstein's sense) is another disciplinary matrix for representing forms of order. A link with neuroscience can be made by using qualitative methods to identify tasks and neuroscience methods of understanding the brain as a tool.

Liver cancer in Asian migrants to the United States and their descendants

The incidence of primary liver cancer in Chinese, Japanese, and Filipino migrants to the United States and their descendants is compared with that of United States-born Whites. Incident liver cancer cases were ascertained between 1973 and 1986 from population-based cancer registries serving the San Francisco/Oakland (CA) metropolitan area, 13 counties of western Washington, and Hawaii. The population of these three areas, with regard to age, race, and country of birth, was estimated from a special tabulation of the 1980 US census. Rates of primary liver cancer were higher for men born in Asia than Asian men born in the US, who, in turn, had higher rates than did US Whites (respective annual rates per 100,000: Chinese, 26.5 and 9.8; Japanese, 16.5 and 6.6; Filipinos, 11.4 and 6.5; US Whites, 3.4). Among Asian American women, the trends were not as consistent (respective annual rates per 100,000: Chinese, 2.2 and 3.7; Japanese, 1.9 and 1.4; Filipino, 2.6 and 0; US Whites, 1.1). In general, liver cancer incidence among Asian Americans was lower than among residents of Asia. These findings are compatible with substantial variation among Asians in the prevalence of one or more etiologic factors for liver cancer, such as hepatitis-B infection and aflatoxin consumption, in relation to residence and place of birth.
Benign mucous membrane pemphigoid. Management of an edentulous patient.

Abstract The use of intralesional injections of triamcinolone acetonide in an edentulous patient produced healing of the oral lesions of benign mucous membrane pemphigoid and allowed the prosthodontist to construct new dentures, thus minimizing further trauma to the oral tissues. The method described will not prevent recurrence of oral ulceration in this condition, but any subsequent severe ulceration can be similarly controlled.
Charting Supply Chain Management Integration and Initiatives: A Framework to Guide Implementation

This paper proposes a framework that describes the boundary spanning supply chain management (SCM) initiatives taken by leading companies. Supported by existing literature and interviews with managers from large companies reflecting a cross section of businesses, the framework suggests four motivating domains or factors that could support SCM initiatives. They are supply chain understanding, design, improvement, and coordination. Based on the sand cone model, the framework also suggests four levels of SCM integration over which these motivating factors are relevant to the firm and/or supply chain. They range from no integration outside the functional silos of a single firm to a fully integrated multi‐tier supply chain. Unlike existing frameworks that are based upon the flow of material and information through the supply chain, our framework is derived by combining the concept of integration with the motivating domains that characterize SCM initiatives. It captures the combined and overlapping impact of supply chain initiatives from a more strategic perspective and is a useful additional resource for practitioners who seek to chart potential improvements to their supply chain from a competitive standpoint.
Designing an information security program as a core competency of network technologists

In the article, "Clarke Warns Educators About the Need for Better Security", Deborah Radcliff states that information security programs focus solely on technology issues without regard to business value and critical thinking. [1] Another issue is the lack of undergraduate programs in information security for front line network engineers and technicians. Most unmet employer needs today consists of front-line workers in the information security field that contains the greatest number of information security jobs in the marketplace. However, few professionals at this level are currently educated and trained in information security. This level is a niche area for undergraduate programs to provide needed education and training in information security. Most information security programs today are at the post-graduate level, which trains for higher level jobs than what most employers are looking for. The purpose of this paper is to review the author's research in information security employer needs, present the high level competencies needed in information security programs as developed by an industry focus group, investigate the different ways to integrate information security into IT programs, and discuss the implications for network technology programs in the future.
