Characterization Of Fibers For 10.6 µm Transmittance

Transmittance measurements were made on short lengths of arsenic trisulfide, arsenic tri-selenide, and KRS-5 fibers at the 10.6- μm wavelength. Significant absorption was noted in all of the fibers; however, improvements in transmittance can be postulated.
Factors predicting childhood respiratory syncytial virus severity: what they indicate about pathogenesis.

Background: A plethora of clinical experience exists defining the factors associated with differences in severity of childhood respiratory syncytial virus (RSV) infections. These clinical severity factors reveal a wealth of information about the pathogenesis of this disease. Reviewing and interpreting the clinical risk factors to gain an insight into RSV pathogenesis is important, especially considering the relative lack of parallel between many animal models of RSV infection and observed human disease. Methods: Existing and unpublished data on severity risk factors are reviewed and placed into a working pathogenesis model. Results: Important factors discussed are: (1) the critical role of the timing of the infection; (2) its rapidity of progression to involve the lower respiratory tract; (3) factors limiting this spread; (4) the nature of the pathogenic immune response; and (5) the host genetic and other factors that alter this immune response. Conclusions: Pending new data involving these and other processes will more fully illuminate the spectrum of childhood RSV disease.

Gait-Based Human Recognition by Classification of Cyclostationary Processes on Nonlinear Shape Manifolds

We study the problem of analyzing and classifying human gait by modeling it as a stochastic process on a shape space. We consider gait as a evolution of human silhouettes as seen in video sequences, and focus on their shapes. More specifically, we define a shape space of planar, closed curves and model a human gait as a stochastic process on this space. Due to the periodic nature of human walk, this process is naturally constrained to be cyclostationary, that is, its mean path is assumed to be cyclic. We compare two subjects using a metric that quantifies differences between average gait cycles of each subject. This computation uses several tools from differential geometry of the shape space, including computation of geodesics, estimation of means of observed shapes, interpolation between observed shapes, and temporal registration of two gait cycles. Finally, we apply a nearest-neighbor classifier, using the gait metric, to perform human recognition, and present results from an experiment involving 26 sub...
Three copies of a single recombination repeat occur on the 443 kb mastercircle of the Petunia hybrida 3704 mitochondrial genome

At 443 kb, the map of Petunia hybrida line 3704 mitochondrial DNA is the largest yet produced from a dicot plant. Regions of similarity to known plant mitochondrial genes and to the chloroplast genome have been placed on a master circle. One long repeated sequence, apparently active in recombination, is present in three copies. Two copies of 6.6 kb occur in a direct orientation and are separated by 199 kb. A third truncated copy of 3.5 kb is inverted relative to the other two and is separated from the others by 99 and 145 kb. The presence of the recombination repeats predicts a multipartite molecular organization, consisting of four master circles and three subgenomic circles. Two other repeated regions were found not to be substrates for, or products of recombination. The absence of recombination at certain reiterated regions indicates that there is specificity of recombination at the recombination repeats.
Serotonin Transporter Genotype Linked to Adolescent Substance Use Treatment Outcome through Externalizing Behavior

Meta-analyses suggest that the serotonin transporter linked polymorphic region (5-HTTLPR) short (S) allele, relative to the long (L) allele, is associated with risk for alcohol dependence, particularly among individuals with early onset antisocial alcoholism. Youth in substance use treatment tend to show antisocial or externalizing behaviors, such as conduct problems, which predict worse treatment outcome. This study examined a pathway in which 5-HTTLPR genotype is associated with externalizing behavior, and the intermediate phenotype of externalizing behavior serves as a link between 5-HTTLPR genotype and substance use treatment outcome in youth. Adolescents (n=142) who were recruited from addictions treatment were genotyped for 5-HTTLPR polymorphisms (S and LG carriers vs. LALA), assessed for externalizing and internalizing behaviors shortly after starting treatment, and followed over 6-months. 5-HTTLPR genotype was not associated with internalizing behaviors, and was not directly associated with 6-month substance use outcomes. However, 5-HTTLPR genotype was associated with externalizing behaviors (S and LG > LALA), and externalizing behaviors predicted alcohol and marijuana problem severity at 6-month follow-up. Results indicated an indirect (p<.05) and non-specific (i.e., both alcohol and marijuana severity) effect of 5-HTTLPR genotype on youth substance use treatment outcomes, with externalizing behaviors as an important linking factor. Adolescents in substance use treatment with low expressing (S and LG) 5-HTTLPR alleles and externalizing behavior might benefit from intervention that addresses serotonergic functioning, externalizing behaviors, and substance use to improve outcomes.
Effects of algal density, water flow and substrate type on culturing juveniles of the rainbow mussel (Villosa iris) (Bivalvia: Unionidae) in a laboratory recirculating system

article i nfo The effects of algal density, water flow and substrate type on the survival and growth of newly metamorphosed juveniles of the rainbow mussel (Villosa iris) were investigated in 40 l recirculating culture systems. A split-plot design with a whole plot factor combining algal density and water flow, and a split-plot factor of substrate were applied in this study to test the three factors. Juveniles reared in 4 juvenile culture units (550 ml) with fine sediment (b200 μm), sand (300-500 μm), limestone gravel (800-1000 μm) and without substrate in each recirculating system receiving water flow at levels of 3.75 ml s −1 or 7.5 ml s
Tumour necrosis factor-α blockers: potential limitations in the management of advanced endometriosis? A Case Report

Several studies have shown that tumour necrosis factor (TNF)-alpha levels are increased in the peritoneal fluid of women with endometriosis, with correlation between TNF-alpha concentrations and the degree of disease. It is also likely that elevation of peritoneal fluids' TNF-alpha levels may play a role in the pathogenesis of infertility associated with endometriosis. Use of drugs such as etanercept, a TNF-alpha receptor immunoglobulin fusion protein which inhibits TNF-alpha activity, showed in an animal study to reduce the severity of the disease, and the size of endometriotic foci. TNF-alpha blockers were recommended as a possible new line of therapy for endometriosis. Our case involved a 35-year-old Para 0, with rheumatic arthritis and stage 4 endometriosis. After 6 years of constant use of etanercept, she showed no improvement of endometriosis as demonstrated at laparoscopy. However, she underwent a successful IVF after the first attempt. TNF-alpha-blocker medications might not be beneficial for patients with advanced endometriosis. However, we cannot exclude the possible effect of these medications on early-stage endometriosis, and further study is required. Some of the immunologic abnormalities in the pelvis of patients with endometriosis could be the consequence of the disease and not the cause, and possibly suppression of immune cells and their products may not have a major effect on endometriotic lesions at an advanced stage. This also could explain why suppression of TNF-alpha showed no effect on infertility. However, use of TNF-alpha-blockers before IVF might increase the success rate in advanced endometriosis.
Substrate impact on the thermal performance of tape automated bonding components

The results of thermally characterizing a 160-I/O (input/output) tape automated bonding (TAB) device are reported. A finite-element technique is used to understand and model the thermal processes of the TAB. A three-dimensional (3-D) computer model is developed and validated against experimental data obtained in a natural convection environment. The 3-D model's results indicate that the thermal processes associated with the TAB are not 2-D in nature. A substantial temperature variation is present across much of the device. Several carriers are modeled with the TAB device to determine their thermal effect on the device's thermal characteristics. Reducing the card's cross-section from a multilayer printed circuit board (PCB) to a board with no internal planes substantially impacts the power dissipation capabilities of the component. The use of a molded rather than an FR4 material in the card has a negligible effect on the thermal characteristics of the attached device due to their similar thermal conductivity. >
Chiral Symmetry, Nonleptonic Hyperon Decay and the Feinberg-kabir-weinberg Theorem

We demonstrate that additional (kaon-pole) diagrams must be appended to the traditional commutator-plus-baryon-pole approach to nonleptonic hyperon decay. The modified analysis satisfied the constraints of the Feinberg-Kabir-Weinberg theorem. The new terms are not numerically significant in the case of the usual current-current Hamiltonian, in the continuum limit, but can be important for work using lattice techniques or for other Hamiltonians.
Phase I and Pharmacokinetic Study of Topotecan Administered Orally Once Daily for 5 Days for 2 Consecutive Weeks to Pediatric Patients With Refractory Solid Tumors

Purpose We conducted a phase I trial of the injectable formulation of topotecan given orally once daily for 5 days for 2 consecutive weeks (qd × 5 × 2) in pediatric patients with refractory solid tumors. Patients and Methods Cohorts of two to six patients received oral topotecan at 0.8, 1.1, 1.4, 1.8, and 2.3 mg/m2/d every 28 days for a maximum of six courses. Twenty patients (median age, 10.6 years) received a total of 51 courses. Eight patients received topotecan capsules during course 2 only. Results Dose-limiting toxicity occurred at 2.3 mg/m2/d and consisted of prolonged grade 4 neutropenia (n = 2), grade 3 stomatitis as a result of radiation recall (n = 1), grade 3 hemorrhage (epistaxis) in the presence of grade 4 thrombocytopenia (n = 1), and grade 3 diarrhea in the presence of Clostridium difficile infection (n = 1). Dose-limiting, prolonged grade 4 neutropenia and thrombocytopenia occurred in one patient at 1.4 mg/m2/d. Infrequent toxicities were mild nausea, vomiting, elevated liver ALT or AST, ...
Kinetic study of olefin polymerization with a supported metallocene catalyst. IV. Comparison of bridged and unbridged catalyst in gas phase

A kinetic study of ethylene/1-hexene (E/1-H) copolymerization is conducted with a supported bridged metallocene catalyst in a gas phase reactor. The investigation into the kinetics of ethylene/1-hexene copolymerization includes the effects of operational parameters such as the reaction temperature, pressure, and comonomer concentration. On-line perturbation techniques are implemented to determine key kinetic parameters such as the activation energies for propagation and catalyst deactivation. A comparison of the kinetic parameters and behavior is made between the bridged and a previously studied unbridged catalyst. Finally, a two-site model is proposed to explain the observed kinetic behavior with changing reaction temperature and comonomer concentration. © 2001 John Wiley & Sons, Inc.

Note: On avoiding odd partial Latin squares and r-multi Latin squares

We show that for any positive integer k>=4, if R is a (2k-1)x(2k-1) partial Latin square, then R is avoidable given that R contains an empty row, thus extending a theorem of Chetwynd and Rhodes. We also present the idea of avoidability in the setting of partial r-multi Latin squares, and give some partial fillings which are avoidable. In particular, we show that if R contains at most nr/2 symbols and if there is an nxn Latin square L such that @dn of the symbols in L cover the filled cells in R where 0<@d<1, then R is avoidable provided r is large enough.
Paradoxical deterioration of left ventricular asynergy after administration of nitroglycerin.

Abstract The effects of nitroglycerin on segmental asynergy were studied by 2-dimensional echocardiography. Forty-five patients with coronary artery disease and segmental wall motion abnormality at rest were examined, 31 with Q-wave and 14 with only ST-T abnormalities. Left ventricular (LV) echocardiograms were recorded from the LV apex in 4 planes, obtained by systematically rotating the transducer at 45 ° intervals around the mitral orifice, using a mechanical device. Sixteen LV segments were analyzed in each patient on real-time display by 2 observers independently. The wall motion analysis was classified as normal, hypokinetic, akinetic or dyskinetic. Of 720 segments, 596 were agreed on by 2 observers in the assessment of wall motion before and after administration of nitroglycerin: 334 segments (56%) showed no change in wall motion, 206 (35%) showed improvement of wall motion and 56 (9%) showed worsening of myocardial asynergy after nitroglycerin. These data suggest that administration of nitroglycerin may result in unexpected worsening of segmentai asynergy. This may be secondary to an adverse effect of a decrease in perfusion pressure in critically occluded arteries or may represent a coronary steal phenomenon.
Incorporating Unusual Fonts and Planned Mistakes in Study Materials to Increase Business Student Focus and Retention

New studies indicate that incorporating planned difficulties such as unusual font styles in study material forces students to focus and concentrate more. In our experiment 155 students under different instructors learn a core topic in operations management in an active learning environment. One group of students in each class used a standard version of the study materials while two other groups used a modified version incorporating an unusual difficult-to-read font or planned mistakes. Students with the unusual font materials scored highest on a post-workshop comprehension test. Students who had workshop materials with pedagogical mistakes scored second followed by students in the control group. Further, it was observed that students in the control group deceived themselves with respect to sense of material mastery.
FLOW BEHAVIOR OF SWEET POTATO PUREE AND ITS RELATION TO MOUTHFEEL QUALITY

. Flow behavior of baked sweet potato puree obtained from eight cultivars was studied in a concentric cylinder viscometer to determine parameters in the non-Newtonian power law equation with a yield stress. This algebraic equation proved to be a suitable flow model. A computational technique to determine model parameters was developed. Yield stress of the cultivars was highly correlated with taste panel scores, an increase in yield stress indicating a less moist mouthfeel. It was observed that, in general, the mouthfeel of sweet potatoes becomes more moist with increased storage up to 40 days; no definite pattern was discovered thereafter.
Real-World Semi-Supervised Learning of POS-Taggers for Low-Resource Languages

Developing natural language processing tools for low-resource languages often requires creating resources from scratch. While a variety of semi-supervised methods exist for training from incomplete data, there are open questions regarding what types of training data should be used and how much is necessary. We discuss a series of experiments designed to shed light on such questions in the context of part-of-speech tagging. We obtain timed annotations from linguists for the low-resource languages Kinyarwanda and Malagasy (as well as English) and evaluate how the amounts of various kinds of data affect performance of a trained POS-tagger. Our results show that annotation of word types is the most important, provided a sufficiently capable semi-supervised learning infrastructure is in place to project type information onto a raw corpus. We also show that finitestate morphological analyzers are effective sources of type information when few labeled examples are available.
A generic reconfigurable array specification and programming environment (GRASPER)

Modern advances in reconfigurable technologies are allowing analog circuit designers to benefit from the computational flexibility provided by large-scale field-programmable analog arrays (FPAAs). With the component density of these devices, small analog circuits as well as larger analog systems can be synthesized and tested in a shorter time and at a lower cost compared to the full design cycle. However, automated development platforms and CAD tools for these devices are far fewer than the physical synthesis tools for their digital counterparts. One of the major reasons for this is the considerably higher impact of interconnect parasitics on circuit functionality in the analog domain; therefore, performance metrics must be monitored closely. Our goal in this paper is to present a physical synthesis framework with a generic architecture specification interface and a parasitic extractor for verification of the synthesis results. Our synthesis tool can support a wide range of FPAA architectures and our simulations can successfully predict the performance metrics.
From Theory Use to Theory Building in Learning Analytics: A Commentary on “Learning Analytics to Support Teachers during Synchronous CSCL”

In this commentary on Van Leeuwen (this issue), I explore the relation between theory and practice in learning analytics. Specifically, I caution the issue of adhering to one specific theoretical doctrine while ignoring others, suggest deeper application of the cognitive load theory to understanding teaching with analytics tools, and comment on issues with theory building in the nascent field of learning analytics.
Our Boggling Constitution; or, Taking Text Really, Really Seriously

This light essay takes a jaunty two-step beyond textualism and beyond intra-textualism, and offers a new approach to constitutional interpretation: intra-intra-textualism. Just as textualism involves taking the whole text of the Constitution seriously, and intra-textualism involves taking the words of the Constitution seriously, so intra-intra-textualism proposes that we take the letters of the Constitution seriously. Inspired by Boggle, and by the various text-twist type games I can't seem to stop playing on my Iphone, intra-intra-textualism, or "Our Boggling Constitution," argues that if the words of the Constitution have authoritative interpretive meaning, then so must its letters -- especially when they are jumbled together and rearranged. Besides offering new sources of legitimacy, flexibility, and professional advancement, Boggling Constitutionalism, unlike most other theories of constitutional interpretation, is also fun for the whole family. This humor piece, which was initially published anonymously, is a nominee in the Green Bag Almanac & Reader's list of exemplary legal writing over the past year.
Near-Surface Motion and Dynamic Adhesion during Silica Microparticle Capture on a Polymer (Solvated PEG) Brush via Hydrogen Bonding

Surface modification by “polymer brushes” (dense end-tethered chains) is a strategy to create a steric barrier against colloidal aggregation or bioadhesion or to facilitate lubrication. The approach requires good brush solvation; however, even in a good solvent, brush chains can adhere certain objects. An important example is the hydrogen bonding of silica to PEG (poly(ethylene glycol)) chains in water. To probe how hydrogen bonding at the brush periphery facilitates adhesive capture of flowing particles, we employ a model system comprising silica microspheres on biorepellant PEG brushes sufficiently thick to screen interactions with the underlying substrate. We find that capture of silica spheres on PEG brushes is slower and less efficient than the transport-limited rate and can be hindered by the addition of salt and by flow, up to wall shears at least 500 s–1. Individual flowing silica microparticles adhere gradually to the PEG brush (presumably by increasing the numbers of H-bonds), so that the partic...
A prototype for a hybrid system to support systematic review teams: A case study of organ transplantation

We describe a prototype for a hybrid system designed to reduce the number of citations needed to re-screen (NNRS) by systematic reviewers, where citations include titles, abstracts, and metadata. The system obviates the need for screening the entire set of citations a second time, which is typically done to control human error. The reference set is based on a complex review about organ transplantation (N=10,796 citations). Data were split into 50% training and test sets, randomly stratified for percentage eligible citations. The system consists of a rule-based module and a machine-learning (ML) module. The former substantially reduces the number of negative citations passed to the ML module and improves imbalance. Relative to the baseline, the system reduces classification error (5.6% vs 2.9%) thereby reducing NNRS by 47.3% (300 vs 158). We discuss the implications of de-emphasizing sensitivity (recall) in favor of specificity and negative predictive value to reduce screening burden.
Ferry Enhanced Improved PRoPHET Routing Protocol

In a Delay Tolerant Network (DTN), where nodes are constantly moving and the connection of nodes are intermittent, messages are delivered by replicating to neighbor nodes in hopes of delivering to the destination in a timely manner. This causes a DTN network to have many duplicates even long after the message has reached its destination. In this paper, we develop a new routing protocol that helps alleviate the amount of unnecessary message duplicates by introducing ferry nodes that have the capability of deleting messages that have already been delivered to the destination nodes in the network. With appropriately designed routes, ferries also help with message delivery. We then analyze the protocol through simulations and verify the performance in terms of message delivery delay, average number of copies created within a network, and message delivery ratio. The experiments show that the proposed protocol has improved performance.
Feedback and Interlock Triggering for Real-Time IMRT Verification

Intensity Modulated Radiotherapy or IMRT may lead to better clinical outcomes by highly conforming dose distributions to the tumor, while limiting doses to surrounding normal tissues. In dynamic IMRT, collimator leaf movement modulates the beam intensity while x-rays are being delivered. Dynamically delivered IMRT treatments are technologically complex with parameters changing during treatment. For example, the beam intensity at any position at a given point in time is a function of accelerator output, MLC leaf position, MLC leaf speed, collimator angle, gantry angle, beam number and beam weighting. The efficacy of highly conformal radiotherapy is dependent on accurate delivery. Thus, we must ensure accurate delivery of the dynamic IMRT treatment prior to and during the patient treatment.
Evaluating the influence of connectivity and distance on biogeographical patterns in the south-western deserts of North America

Aim To examine the role of geological history, connectivity and distance in shaping the biogeographical structure of North American desert clades that are restricted to habitat islands (sand dunes and relictual aquatic habitats), using statistical model choice on old and new probabilistic biogeographical models. Location North America, Mojave, Sonoran and Chihuahuan Deserts. Materials and methods Dated phylogenies were estimated for three field-sampled insect clades (Trigonoscuta, Rhaphiomidas and sand treader crickets), and five other literature-sampled clades (the snails Assiminea, Pyrgulopsis and Tryonia; the desert fringe-toed lizard Uma; and the desert pupfish Cyprinodon). BioGeoBEARS was used to statistically compare biogeographical models assuming unconstrained or connectivity-constrained dispersal, with or without founder-event speciation (jump dispersal) permitted. Finally, we introduce and test a novel distance-based dispersal model (+x) where dispersal probability is multiplied by distance to the power x. Results We observed little concordance between biogeographical patterns and timing of geological events. Model comparisons were decidedly in favour of inclusion of founder-event speciation in the models for most taxa, with only a small taxon, Uma, showing support for the model favouring vicariance. The inclusion of a constrained-dispersal matrix was favoured by three of the eight taxa examined (Cyprinodon, sand treader crickets, and Trigonoscuta). Surprisingly, tests for distance influencing dispersal probability were mostly negative. Main conclusions Our results do not show support for any one geological event shaping the biogeographical patterns of these desert taxa. Instead, the histories of desert dune and aquatic taxa are largely products of rare jump dispersal events, and can be considered island-like systems. Although results are negative for the distance-based dispersal model, this in itself demonstrates the superiority of explicit statistical model testing over a priori assumption of fixed models in historical biogeography.
Geometric and Electronic Structure of Fullerene Film Growth as a Function of Coverage

We have employed scanning tunneling microscopy at room and low temperature, i.e. 300, 50, and 5 K, to study the epitaxy and growth of fullerene films on the noble-metal surfaces Ag(110) and Au(110). Initial island growth occurs on terrace sites away from substrate step edges. Particularly at low temperatures where the rotational and vibrational movements of the fullerene molecules are frozen in, different intra-molecular topographic patterns become visible in ordered films, which are characteristic of particular adsorption sites. Complementary tunneling spectroscopy and direct and inverse photoemission measurements reveal distinct differences between the first adsorbed monolayer and additional fullerene layers indicating differences in bonding and charge transfer. Our results are compared to theoretical calculations.
Validation of Driving Simulators

This paper, from a special issue on driving simulator applications in research and clinical practice, provides a literature review of driving simulator validation studies. The author stresses that simulator validity is a complex and multi-faceted issue. Thus, there is a controversy regarding whether or not driving simulators are valid and reliable predictors of on-road driving performance. The author addresses the possible reasons for the controversy, suggests using health measurement terminology for simulator validity, and offers ways to match the types of measurement validity terms with examples of existing diving simulator validation studies. Specific types of validity discussed include face and content validity; construct validity; and criterion-related validity, including concurrent and predictive. This paper is an expansion of the 2010 STISIM User Conference Keynote lecture on validating driving simulators.
Employment Status and Poor Adult Health Outcomes Among Lesbian, Gay, and Bisexual Individuals

Letters to the editor are presented in response to the article "Adverse childhood experiences related to poor adult health among lesbian, gay, and bisexual individuals," by A. Austin, H. Herrick and S. Proescholdbell, which appeared within volume 106, number 2 during 2016.
Analysis of Sequential Clinical Trials

We discuss issues and methods for the analysis of clinical trials that have formal rules for what is commonly referred to as early stopping. However, we take a broader view, and include trials having a formal sequential stopping rule; the distinction will soon become apparent. Moreover, it is impossible to separate the analysis of such trials from their design, and so we must, of necessity, provide an overview of the design—that is, specification of the stopping rule—of a sequential clinical trial as well.
Full replacement of menhaden fish meal protein by low-gossypol cottonseed flour protein in the diet of juvenile black sea bass Centropristis striata

Abstract Eight isonitrogenous (46% crude protein) and isolipidic (14% crude lipid) diets were formulated for juvenile black sea bass Centropristis striata to replace menhaden fish meal (FM) protein (59.5% CP) by three cottonseed meal (CSM) proteins: a CSM prepared from glandless seed (GCSM, 50.4% CP), a CSM that had been solvent extracted with acidic ethanol to remove the gossypol (SCSM, 53.8% CP), and a CSM prepared from regular (glanded) cottonseed (RCSM, 45% CP). Three diets replaced 50, 75 and 100% of FM protein with GCSM, and three diets replaced 50, 75 and 100% of FM protein with SCSM. One diet replaced 100% FM protein with RCSM protein. A control diet (0% CSM) was formulated with high FM protein and other practical protein sources. l -methionine and l -lysine were supplemented to the diets to equal the control diet. Fifteen fish were stocked in each of twenty-four 75-L tanks, and each test diet was fed to triplicate groups of fish (mean initial weight = 7.7 ± 0.10 g) for 56 days at 22–24 °C, 32–35 salinity, and ambient photoperiod conditions. Fish were fed twice per day to apparent satiation. Final (day 56) mean body weight (BW, 24.16–31.62 g), body weight gain (BWG, 211.2–311.3%), specific growth rate (SGR, 1.70–2.18%/d), and feed intake (FI, 0.37–0.43 g/fish/d) were not significantly different (P > 0.05) among the control, GCSM or SCSM treatments, but were reduced (P Statement of relevance Cotton seed flour is an inexpensive agricultural by-product. The results demonstrate successful replacement of fish meal protein with genetically-improved cottonseed flour protein in the diet of black sea bass. These findings may substantially lower aquafeed costs (a key operational cost) for finfish growout operations to boost profitability and accelerate expansion of commercial production of black sea bass and other finfish species.
Abandoning Antitrust's Chicago Obsession: The Case for Evidence-Based Antitrust

The antitrust community retains something of an inconsistent attitude towards evidence-based antitrust. Commentators, judges, and scholars remain supportive of evidence-based antitrust, even vocally so; nevertheless, antitrust scholarship and policy discourse continues to press forward advocating the use of one theory over another as applied in a specific case, or one school over another with respect to the class of models that should inform the structure of antitrust’s rules and presumptions, without tethering those questions to an empirical benchmark. This is a fundamental challenge facing modern antitrust institutions, one that I call the “model selection problem.” The three goals of this article are to describe the model selection problem, to demonstrate that the intense focus upon so-called schools within the antitrust community has exacerbated the problem, and to offer a modest proposal to help solve the model selection problem. This proposal has two major components: abandonment of terms like “Chicago School,” “Neo-Chicago School,” and “Post-Chicago School,” and replacement of those terms with a commitment to testing economic theories with economic knowledge and empirical data to support those theories with the best predictive power. I call this approach “evidence-based antitrust.” I conclude by discussing several promising approaches to embedding an appreciation for empirical testing more deeply within antitrust institutions.
The Varied Origins of Voltage Collapse in the Large Power Systems

Abstract Voltage collapse has many causes of varied nature ranging from parameter changes to events connected with faults. The most common type of voltage collapse studied in the field is that connected with the saddle node bifurcation (P-V curve). Using a comprehensive theory of power system dynamics recently developed by us, it is possible to identify and classify many different origins of voltage instabilities. Such a classification is given here after the theory is briefly summarized. The various cases are illustrated using simulation results. This is not a survey of the literature however.
Modelling the effect of temperature on the gel-filtration chromatographic protein separation

Abstract In this study a mechanistic model for chromatography was taken and the solution to its Laplace transfer function was obtained using the Fast Fourier Transform method. Using previously developed correlations for modelling diffusion, both in solution and intraparticle, and estimating the mass transfer coefficient, the effect of temperature in gel fittration liquid chromatography was investigated. The effect of each individual parameter on the elution curve was systematically explored allowing for reasonable estimates for the different temperature cases. In this case, a system of bovine serum albumin and phenylalanine separated by gel filtration chromatography was simulated to demonstrate how the resolution and the selectivity of the separation will change with physical parameters. Decreasing the particle size and flow rate while increasing the temperature led to higher resolution, which is consistent with experimental literature data.
PLOTS GEEN BLOEDPLAATJES MEER

Coincidenties komen voor. Binnen enkele dagen vragen twee tandartsen advies over een patient met trombocytopenie. Een van beide patienten meldt dat hij kortgeleden is behandeld, omdat hij rare huidafwijkingen kreeg, vooral aan zijn onderbenen. Daarbij bleek dat hij‘plotseling nog maar 10 bloedplaatjes had’. De patient vervolgt met de opmerking:‘Het is nu weer aardig goed’. Het was een bijzondere ziekte en het kon terugkomen. Het plan van deze tandarts en patient was een uitgebreide parobehandeling inclusief chirurgie te starten in een mond met slechte mondhygiene. De woorden van de patient waren niet echt geruststellend. Het mailtje van de tandarts aan mij was veelomvattend:‘Lost u dit probleem eens voor mij op’.

Diagnosis and Management of Acute Kidney Injury in Critical Illness

This is an exciting time in the world of acute kidney injury (AKI) research as there are new developments in methods to provide earlier diagnosis, streamline management, and offer additional therapeutic options via renal replacement therapy that would have otherwise not been a possibility a few years ago. However, questions still remain of our ability to appropriately diagnose and manage patients at risk for AKI. Is current therapy good enough? Are we moving in the right direction? The purpose of this chapter is to not focus on the physiology of AKI but to discuss advancements in early detection and management while at the same time recognizing that there is still much to be done.
Electrical-Stimulation Research: Present Concepts and Future Directions

Many discoveries in science have lain unused and dormant for years until their significance was recognized and they could be used in practical situations. Recent and continuing advances in electronics technology and the spectacular progress anticipated in genetic engineering exemplify this “learn now, apply later” category, for, without prior knowledge on which they could be constructed, these subjects would not exist at all.
Heat and Steam Treatments

Heat-based processes have been used for centuries for food preservation and still remain the most widely used preservation technique in food manufacturing. However, thermal processing treatments are not as efficacious in the destruction of pathogenic microorganisms at low water activities compared to moist environments. Several dry-heat processes have been applied to low-moisture foods and include drying, hot air and baking, air impingement, dry roasting, and oil roasting. These applications require higher temperatures and longer heat times to obtain equivalent lethality to moist-heat processes. Moist-heat processes, which include blanching, moist-air impingement, and controlled condensation steam, are very effective at inactivating microorganisms because the added moisture significantly reduces microbial thermal resistance. However, an increased moisture content of the product can reduce the shelf life, often resulting in the necessity for the (energy consuming) re-drying of product to remove the added moisture. Lastly, extrusion has been shown to be an effective process for microbial inactivation.
Digital Reading Programs: Definitions, Analytic Tools and Practice Examples

Access to a growing number of digital reading platforms containing large e-book collections is changing the landscape of independent reading in schools. This chapter provides an overview of digital reading programs and offers insight into available tools that can be used to evaluate digital book design, focusing on the structural qualities of e-book programs that may offer affordances to beginning readers beyond traditional print books. The authors discuss tools to evaluate digital reading programs at four levels: the program level, the book level, the individual screen page level, and the dashboard analytics offered in the program. In addition to best practice examples, the authors also offer guidance about how classroom teachers can use the tremendous efficiency of digital reading platforms to more actively promote the longstanding principle of learning by doing in the act of reading – helping students to focus on practicing the essential skills they need to read and to read with enjoyment.
Optimization of solid-phase microextraction (SPME) for the recovery of explosives from aqueous and post-explosion debris followed by gas and liquid chromatographic analysis

Solid-phase microextraction (SPME) has been evaluated for the recovery of explosives residues from aqueous samples and real post-explosion solid debris samples and optimized using gas chromatography with an electron capture detector (GC-ECD) and high-performance liquid chromatography with ultraviolet detection (HPLC-UV). A modified SPME/HPLC interface utilizing dual six-port valves allowed for independent optimization of SPME desorption and injection variables that provided improved chromatographic resolution and sensitivity. A unique combination of cyano and octadecyl columns resulted in the complete separation of the 14 explosives in EPA method 8330 mixture using HPLC with good quantitative results. At the optimum SPME conditions, the limits of detection (LOD) were found to be of 5 ng/mL to 16 ng/mL of explosives in water and 10 μg/kg to 40 μg/kg of explosives from soil. The technique has been successfully applied to the analysis of real post-explosion debris and can be adapted for use in the field utilizing portable chromatographic instruments.

Planning of Capacity Additions for Voltage Drop Limited Primary Distribution Systems

In studying primary distribution systems necessary for feeding a given area, there is a variety of circuit configurations that could be analyzed. In this paper useful equations for determining future feed points are derived for grid and diamond load areas as a function of load density, conductor size and primary distribution voltage level. The formulas developed are based on the primary voltage drop of the main feeder and laterals between the substation feed point and the last distribution transformer. The simulation results are needed in order to illustrate the fundamental relationship between different electrical and geometric parameters and their impact on the distribution feeder size and area fed. Each circuit layout has its own merits for a particular set of circumstances and the comparative advantages are evident from the curves obtained.
Cell interactions in collective cell migration

Collective cell migration is the coordinated movement of a physically connected group of cells and is a prominent driver of development and metastasis. Interactions between cells within migrating collectives, and between migrating cells and other cells in the environment, play key roles in stimulating motility, steering and sometimes promoting cell survival. Similarly, diverse heterotypic interactions and collective behaviors likely contribute to tumor metastasis. Here, we describe a sampling of cells that migrate collectively in vivo, including well-established and newer examples. We focus on the under-appreciated property that many - perhaps most - collectively migrating cells move as cooperating groups of distinct cell types.
Mitochondria: A Microcosm of Darwinian Competition.

Summary Resource limitation underlies competition in the living world, even between intracellular populations of mitochondria. A new study shows that reducing the availability of an essential cellular resource, namely the enzyme that replicates mitochondrial DNA (mtDNA), can alter the selective advantage of one mtDNA type over another.
Maternal weight affects placental DNA methylation of genes involved in metabolic pathways in the common marmoset monkey (Callithrix jacchus).

Accumulating evidence suggests that dysregulation of placental DNA methylation (DNAm) is a mechanism linking maternal weight during pregnancy to metabolic programming outcomes. The common marmoset, Callithrix jaccus, is a platyrrhine primate species that has provided much insight into studies of the primate placenta, maternal condition, and metabolic programming, yet the relationships between maternal weight and placental DNAm are unknown. Here, we report genome-wide DNAm from term marmoset placentas using reduced representation bisulfite sequencing. We identified 74 genes whose DNAm pattern is associated with maternal weight during gestation. These genes are predominantly involved in energy metabolism and homeostasis, including the regulation of glycolytic and lipid metabolic processes pathways.

Behavioral and neurological effects of tDCS on speech motor recovery: A single-subject intervention study

Abstract This paper reports a feasibility study designed to evaluate the behavioral and neurological effects of using transcranial direct current stimulation (tDCS) in conjunction with speech motor learning treatment for individuals with acquired speech impairment subsequent to stroke. Most of the research using tDCS to enhance treatment outcomes in stroke recovery has focused on either limb motor control or aphasia treatment. Using a multiple-baseline multiple-probe crossover design, we compared both behavioral and brain connectivity-based outcomes following speech motor learning treatment with both Active tDCS and Sham tDCS. We observed that both treatment phases led to improvement in short-term maintenance, but that Active tDCS was associated with greater long-term maintenance improvement. Active tDCS was also associated with an increase in functional connectivity in the left hemisphere and interhemispherically in an ROI-based network analysis examining correlations among areas associated with speech production and acquired speech impairment. This report supports the possibility that tDCS may enhance both behavioral and neurological outcomes and indicates the importance of additional work in this area, although replication is required to confirm the extent and consistency of tDCS benefits on speech motor learning treatment outcomes.
Fixed-accuracy confidence interval estimation of P(X > c) for a two-parameter gamma population

The gamma distribution is a flexible right-skewed distribution widely used in many areas, and it is of great interest to estimate the probability of a random variable exceeding a specified value in survival and reliability analysis. Therefore, the study develops a fixed-accuracy confidence interval for P(X > c) when X follows a gamma distribution, Γ(α, β), and c is a preassigned positive constant through: 1) a purely sequential procedure with known shape parameter α and unknown rate parameter β; and 2) a nonparametric purely sequential procedure with both shape and rate parameters unknown. Both procedures enjoy appealing asymptotic first-order efficiency and asymptotic consistency properties. Extensive simulations validate the theoretical findings. Three real-life data examples from health studies and steel manufacturing study are discussed to illustrate the practical applicability of both procedures.
