To Do or Not to Do: Metadata-Guided Query Evaluation in Content Caching Networks

To support emerging pervasive computer applications, efficient data access and information sharing is essential in mobile wireless environments. The data-centric storage approach provides energy-efficient data dissemination and organization. However, wireless devices have limited storage and are energy-constrained. To address these issues, we introduce the concept of content caching networks, in which the collected data will be stored by its content in a distributed manner, while the data in the network is cached for a certain period of time before it is sent to a centralized storage space for backup. Further, we propose the metadata-guided query evaluation approach to achieve query efficiency in content caching networks. Our clustering and compression based algorithm for metadata construction helps to minimize the information loss due to data compression, while achieving the memory requirements on wireless devices. We present both theoretical and empirical results to show that our metadata-guided approach is highly effective to perform efficient data queries, and thus demonstrate the feasibility of the content caching networks.
Panel Stratification in Meta-Analysis of Economic Studies: An Investigation of Its Effects in the Recreation Valuation Literature

Statistical summarizations of literature review databases using meta-regression analysis provide insight into the differences in past estimates of economic variables such as benefits and price elasticities. The panel nature of the data is an issue that has not received adequate attention in past meta-analyses. This paper conceptually and empirically explores the complexity of stratifying data into panels that model the potential correlation and heterogeneity of past outdoor recreation benefit research. Although our tests of three stratifications of the data did not discern panel effects, the inherent complexity of the data maintains a strong presumption of heterogeneous strata.
Phonomicrosurgical management of intracordal cysts

Patients with intracordal lesions complain of an increase in vocal roughness, early vocal fatigue, and a loss of range. The term intracordal may be misleading; the lesions discussed in this article are nonmalignant masses in or just below the epithelial cover of the vocal fold. Laryngeal videostroboscopy (LVS) is the gold standard for the evaluation of patient's intracordal lesions. The timing of surgery depends on the presence of continued dysfunction despite maximal medical and behavioral interventions. The microflap surgical technique is based upon the immunohistochemical characteristics of benign vocal fold lesions, including intracordal cysts. The dissection, within the superficial layer of the lamina propria, spares the overlying mucosal cover and underlying vocal ligament, optimizing vocal outcome.
Exploring Relationships Between the Global and Regional Measures of Spatial Autocorrelation

The objective of this research is to investigate dimensions of geographic variation in spatial dependency contained within large multilevel data sets. We calculate 1990 population density by census block group, county, and state for the 48 coterminous states and the District of Columbia of the United States, calculations of interest to a wide variety of spatial scientists. We explore relations between these levels and their variation across the nation. The empirical findings generated by this work furnish implications concerning the Modifiable Areal Unit Problem (MAUP), spatial autocorrelation statistics, scale effects, and resolution.
Regular Article: An Accurate Curved Boundary Treatment in the Lattice Boltzmann Method

The lattice Boltzmann equation (LBE) is an alternative kinetic method capable of solving hydrodynamics for various systems. Major advantages of the method are due to the fact that the solution for the particle distribution functions is explicit, easy to implement, and natural to parallelize. Because the method often uses uniform regular Cartesian lattices in space, curved boundaries are often approximated by a series of stairs that leads to reduction in computational accuracy. In this work, a second-order accurate treatment of the boundary condition in the LBE method is developed for a curved boundary. The proposed treatment of the curved boundaries is an improvement of a scheme due to O. Filippova and D. Hanel (1998, J. Comput. Phys.147, 219). The proposed treatment for curved boundaries is tested against several flow problems: 2-D channel flows with constant and oscillating pressure gradients for which analytic solutions are known, flow due to an impulsively started wall, lid-driven square cavity flow, and uniform flow over a column of circular cylinders. The second-order accuracy is observed with a solid boundary arbitrarily placed between lattice nodes. The proposed boundary condition has well-behaved stability characteristics when the relaxation time is close to 1/2, the zero limit of viscosity. The improvement can make a substantial contribution toward simulating practical fluid flow problems using the lattice Boltzmann method.
Graph-theoretic models for the Fibonacci family

The well-known Fibonacci and Lucas numbers continue to faxcinate the mathematical community with their beauty, elegance, ubiquity, and applicability. After several centuries of exploration, they are still a fertile ground for additional activities, for Fibonacci enthusiasts and amateurs alike. Fibonacci numbers F n and Lucas numbers L n belong to a large integer family { x n }, often defined by the recurrence x n = x n −1 + x n −2 , where x 1 = a , x 2 = b , and n ≥ 3. When a = b = 1, x n = F n ; and when a = 1 and b = 3, x n = L n . Clearly, F 0 = 0 and L 0 = 2. They satisfy a myriad of elegant properties [1,2,3]. Some of them are: In this article, we will give a brief introduction to the Q -matrix, employ it in the construction of graph-theoretic models [4, 5], and then explore some of these identities using them. In 1960 C.H. King studied the Q -matrix
ELF: A Program Synthesis Architecture

ELF is a program architecture: an organization of synthesis strategies aimed at transforming an abstract, non-executable description of a software tool into real, working software. Although ELF relies on many program synthesis ideas, the real focus of the ELF prototypes is to illustrate the feasibility of integrating domain knowledge and program synthesis knowledge for the automatic generation of real-world application tools. Maze routers are our target application domain. However, it is important to understand that ELF is a prototype. We do not expect to be able to generate a perfectly tuned, perfectly customized, high-performance router; rather our intent is to demonstrate the feasibility of automatically generating tools. Hence, we intend to focus on the construction of “reasonably functional and efficient” routers from only a high-level description of the routing task and from domain knowledge. As we shall see in subsequent chapters, we measure success by our ability to generate and demonstrate such routers, and to retarget the ELF generator to different maze router variants. Producing routers over a variety of technologies illustrates how this architecture copes with shifting technology environments. This chapter introduces the major components of the ELF architecture, and the basic synthesis strategies and representation schemes used by ELF.
Channel detection in microscope images of materials using marked point process modeling

In this paper, using the Marked Point Process (MPP) framework, we propose a new model and method to detect channels in microscope images of materials. The detected channel configuration information is expected to be useful for analyzing materials images in many ways. As one example of the possible usage of this channel information, we propose a method to reduce bridging channel defects in the segmentation of images containing channels. Our experimental results demonstrate that proposed model and methods works effectively for both detecting channels and aiding segmentation.
Myosin Light Chain Kinase Binding and Transiting along and between Actin Filaments and Stress Fibers

The physical mechanism of Myosin Light Chain Kinase (MLCK) transiting between Smooth Muscle Myosin (SMM) molecules in a cell is incompletely understood. It is an interesting problem because the MLCK:SMM ratio is remarkably low (1:100) in smooth muscle cells yet smooth muscle activation still occurs on a sub-second time scale. We have shown that one MLCK can rapidly move between myosin molecules associated with a given actin filament by diffusing along that actin track and that MLCK can jump tracks. The diffusive rate along, and the jumping rate between, actin filaments could be significant determinants of the rate of smooth muscle activation. Here we use single particle tracking to understand the diffusive and jumping rates of the n-terminal (actin binding) domain of MLCK-QDots along and between actin filaments. We observe that the frequency of jumping increases as the distance between filaments decreases exponentially, consistent with a simple electrostatic model. Our experimentally measured jumping frequency and diffusion coefficient allow us to more accurately model the rate of smooth muscle activation as a function of MLCK:SMM ratios and the distance between actin filaments in smooth muscle cells.View Large Image | View Hi-Res Image | Download PowerPoint Slide
Epinephrine Secretion in Hypophysectomized Dogs

Our investigation arises from the supposed relation of the adrenal glands to the etiology and pathology of diabetes and of hypertension. This report concerns the probable interrelated functions of the adrenals and the hypophysis, in relation to these conditions.Anatomic changes have been found in the adrenals after hypo-physectomy and in the hypophysis after adrenalectomy. The adrenal cortex undergoes marked atrophy following hypophysectomy although the medulla shares but little, if at all, in this change. Extracts of the posterior lobe of the hypophysis have been reported to be capable of inducing hyperplasia of the adrenal cortex.1 An interrenalotropic principle, capable of affecting the adrenal cortex, has been obtained from the anterior lobe of the hypophysis and an adrenotropic action of hypophyseal extracts, affecting the medulla, has also been reported. It has been claimed2 and also denied3, 4 that the hypertensive action of posterior pituitary extract depends upon free circulation of blood from th...
Effect of Dietary Iron and Copper on Mortality of Chicks at two Temperatures

Abstract In two trials, 1920 mixed-sex commercial broiler chicks 1 day of age were placed in batteries in four environmental chambers described by Reece and Deaton (1969). The temperature was maintained at 32.2°C. for an initial period of 72 hours. The temperature was then reduced 2.8°C. per day in three chambers until a temperature of 21.1°C. was reached. One chamber was maintained at 32.2°C. and three chambers were maintained at 21.1°C. for the 21-day experimental period. The birds were fed diets containing various levels of iron and copper for the 21-day experimental period. Results show that with a purified type diet containing 15 p.p.m. Fe and 3 p.p.pm. Cu, chick mortality at 21.1° and 32.2°C. was due to a deficiency of both Fe and Cu, but Cu was first limiting and exerted a greater effect than Fe.
Effects of Feeding Polychlorinated Biphenyls to Broiler Cockerels in Three Dietary Regimes

Abstract Polychlorinated biphenyls (Aroclor 1242 and 1254) were fed at 20 p.p.m. to hybrid broiler cockerels between one and nine weeks of age in three dietary variations. The Aroclors did not affect growth or feed efficiency and no consistent histopathological lesions could be attributed to them. There was a low incidence of hydropericardium in birds receiving Aroclor 1254. Fatty liver was observed in some birds receiving Aroclor 1242 and a single bird receiving this PCB exhibited liver necrosis. Moderate increases in liver weight and mild decreases in the relative weight of the spleen were attributable to PCB.
Beyond “Difference”: Examining the Process and Flexibility of Racial Identity in Interracial Marriages

This article examines the definitions of “race” used in discussing interracial marriage, arguing that the common framework of “cultural differences” used in existing literature insufficiently describes the range of experiences in interracial marriage. By redefining race as a process of classification that is neither about cultural nor biological “difference,” we use racial formation theory to examine racial identity within interracial marriages and how racial identity might be reclassified as a function of interracial marriage status (i.e., comparing oneself to a different racial group). Finally, we discuss individual-level implications with respect to how interdependence theory affects racial identity and marital quality in interracial marriages.
Lymphedema. Pathogenesis, prevention, and treatment.

Purpose The author discusses the lymphatic circulatory system and the pathogenesis, risk and protective factors, complications, and treatment of lymphedema. Quality-of-life issues, educational needs of patients and families, and suggestions for future research also are addressed. Overview Chronic lymphedema of the arm after axillary lymph node dissection is a potential sequela of breast cancer treatment that has a profound impact on quality of life. Lymphedema may occur any time during the patient's life triggered by even minor trauma, with subsequent inflammation of the affected arm. Treatment of lymphedema may be uncomfortable and unsuccessful. Physical and psychological well-being can be affected negatively by the illness or its treatment. Clinical implications All healthcare professionals coming in contact with individuals having an axillary lymph node dissection need to be aware that the risk of lymphedema is life-long. Specific measures to prevent trauma to the affected arm are noted.
A Post-Colonial Bouillabaisse: Africans in France — Context and Theory

This chapter provides historical and contemporary contextual information and theoretical perspectives to frame and illuminate the experience of Sub-Saharan Africans living in France. First, I discuss how most of the Sub-Saharan Africans in France today are part of a colonial legacy in which Sub-Saharan African immigrants are linked historically and culturally to France, and how these immigrants from different regions and countries constitute a colonial bouillabaisse with shared francophonie (French-speaking) status. I then profile the magnitude of Sub-Saharan Africans as a group compared to other immigrant groups, and in doing so examine the issue of accurately counting those of Sub-Saharan African descent. I next consider the foundations for identity and citizenship in metropolitan France as they may involve the internalization of French culture, jus soli (ties to soil), and the unevenness that manifests itself across immigrant groups. Last, I discuss the history, development, economic marginalization, and social isolation of the banlieues (suburbs) of France today, which are largely inhabited by resident immigrants and those of immigrant descent. In the final section, I introduce the relevant theories and concepts guiding this analysis.
Structure-Activity Relationships of Adrenergic Compounds on the Adenylate Cyclase of Frog Erythrocytes

Frog erythrocyte adenylate cyclase possesses characteristics of a beta-2 adrenergic receptor; this enzyme was used to test various adrenergic compounds for their effects on cyclic 39, 59-AMP formation. Agonists demonstrate different EC50 values and intrinsic activities. A large amino substituent and a hydroxyl group in the levo configuration at the β-carbon increase the potency of agonists and antagonists, but neither modification is essential for activity. Compounds containing a methyl group at the α-position with the erythro configuration retain their agonist or antagonist activities. Agonists must have two functional groups on the phenyl ring; a functional group other than hydroxyl can be substituted only at position 3. The effect of ring substitution on the activity of an antagonist depends on the nature of the adjacent functional group. Studies with trimethoquinol suggest correlation of the observed EC50 with affinity. There is an excellent correlation between activation of frog erythrocyte adenylate cyclase by the agonists studied and the physiological responses in mammalian preparations.
Accelerating Convergence of Branch-and-Bound Algorithms For Quadratically Constrained Optimization Problems*

We consider methods for finding global solutions to quadratically constrained programs. We present a branch-and-bound algorithm which solves a sequence of linear programs, each of which approximates the original problem over a hyperrectangular region. Tightening the bounds produces arbitrarily tight approximations as the volume of the hyperrectangle decreases. Computational experiments are given which relate the efficiency of the algorithm to the input parameters. In order to reduce the amount of work necessary to isolate global solutions within a small region, local optimization techniques are embedded within the branch-and-bound scheme. In particular, the use of the interval Newton method applied to the KKT system is discussed and shown to be computationally beneficial. Extensions are considered which allow the branch-and- bound algorithm to process more general nonlinear functions than quadratic.
Performance of an Artificial Pancreas System for Young Children with Type 1 Diabetes

Abstract Background: Young children 5–8 years old with type 1 diabetes (T1D) exhibit clear needs for improved glycemic control but may be limited in their ability to safely interact with an artificial pancreas system. Our goal was to evaluate the safety and performance of an artificial pancreas (AP) system among young children with T1D. Research Design and Methods: In a randomized, crossover trial, children with T1D age 5–8 years were enrolled to receive on separate study periods (in random order) either the UVa AP using the DiAs Control Platform software with child-resistant lock-out screens (followed as an out-patient admission) or their usual insulin pump+continuous glucose monitor (CGM) care at home. Hypoglycemic events and CGM tracings were compared between the two 68-h study periods. All analyses were adjusted for level of physical activity as tracked using Fitbit devices. Results: Twelve participants (median age 7 years, n = 6 males) completed the trial. Compared to home care, the AP admission resu...
A generalized neural network architecture based on distributed signal processing

In this paper, an unstructured neural network based on the mathematics of holographic storage is presented. While the holographic process is analyzed by the distributed signal processing principles, the neural network architecture is adapted to the generalized support vector machine. This work is inspired by similarities between brain waves and the wave propagation and subsequent interference patterns seen in holograms. Then the mathematics to produce a general mathematical description of the holographic process is analyzed. From this analysis it is shown that how the holographic process can be used as an associative memory network. This aspect, makes this neural network formation process particularly useful for control
The effects of prolonged thermal

Aluminum-lithium alloys are currently being considered for applications at moderately elevated temperatures; accordingly, a study has been made on the effects of prolonged (100 and 1000 hours overaging) thermal exposure at 149 °C and 260 °C on the mechanical properties of a peakaged Al-Li-Cu-Mg-Zr alloy 8090-T8771. In the as-received T8771 temper, the alloy exhibits an excellent combination of strength (˜500 MPa) and toughness (35 MPa√m) with moderate tensile elongation (4 pct). Overaging at 149 °C results in a ˜50 pct reduction in ductility and toughness, primarily associated with the growth of equilibrium phases along grain/subgrain boundaries, resulting in formation of solute-depleted precipitate-free zones and coarsening of matrix8' andS precipitates; strength levels and fatigue-crack growth rates, however, remain largely unchanged. Thermal exposures at 260 °C, conversely, lead to dramatic reductions in strength (by ˜50 to 80 pct), toughness (by ˜30 pct) and fatigue-crack propagation resistance; crack-growth rates at all ΔK levels above ~5 MPa√m are 2 to 3 orders of magnitude faster. Microstructurally, this was associated with complete dissolution of δ′, severe coarsening ofS andT 2 precipitates in the matrix, and formation of equilibrium Cu- and Mg-rich intermetallic phases in the matrix and along grain boundaries. The resulting lack of planar-slip deformation and low yield strength of 8090 following overaging exposures at 260 °C increase the cumulative crack-tip damage per cycle and reduce the tendency for crack-path deflection, thereby accelerating fatigue-crack growth rates. Despite this degradation in properties, the 8090-T8771 alloy has better strength retention and generally superior fatigue-crack growth properties compared to similarly overaged Al-Li-Cu-Zr 2090 and Al-Cu-Zn-Mg 7150 alloys.

Phosphorus Distribution in Soils Treated with Bioenergy Co-product Materials following Corn Growth

This research was conducted to investigate the impact of corn cob gasification biochar (CCGB), switchgrass pyrolysis biochar (SPB), turkey manure ash (TMA), and triple superphosphate fertilizer (TSP) on soil phosphorus (P) distribution in three agricultural soils from Minnesota, USA. Understanding how biochar can change soil P distribution is crucial to develop best management practices for recycling biochar products. Phosphorus sources were incorporated at rates of 0, 28, 56, and 84 mg PO kg to 1.5 kg of each soil in 2-L pots. Corn (L.) plants were grown (2 plants pot) in treated soils for 56 d after emergence. After 56 d, plants were harvested and soil samples collected for sequential P fractionation (HO, 0.5 mol L NaHCO, 0.1 mol L NaOH, and 1.0 mol L HCl) and enzymatic hydrolysis. The results of the sequential fractionation showed that CCGB and SPB were as effective as TSP and TMA at increasing total P extractable in water and HCl. In contrast, the increase in NaHCO and NaOH extractable total P was higher with TSP and TMA than with the CCGB and SPB. In most cases, the increase in inorganic P was similar between biochar and TSP, suggesting that biochar could supply equal amounts of plant available P as commercial fertilizer. The effects of biochar on enzymatically hydrolysable P were not consistent and varied by soil. In conclusion, the results of this study showed that biochar has potential to increase the available P pools in soils similar to commercial fertilizer.
Abstract 14896: Cardiovascular Events and Healthcare Utilization Among Long-term Adult Cancer Survivors Relative to Comorbidity-matched Controls

Preliminary exploration of a computerized cognitive battery and comparison with traditional testing in patients with high-grade glioma.

Background Cognitive function is an important outcome measure in many brain tumor clinical trials, and investigators are interested in employing the most efficient methods of cognitive assessment for this purpose. Computerized testing can be appealing because of the perceived ease of use and electronic data generated. Traditional tests may have the advantage of accumulated validity evidence and comparability across historic trials. Methods We evaluated feasibility of a Cogstate battery in 39 patients with high-grade glioma, and compared it with a commonly used paper-and-pencil battery. Results Both batteries were well tolerated and rated equally likeable. Correlations between the batteries were low to low-moderate. More patients showed impairment at baseline and decline across trials on traditional tests. Conclusions Both batteries were well tolerated, but the most complicated tasks (from both batteries) could not be completed by all subjects. Preliminary validity evidence for the Cogstate tasks was mixed, but a larger sample is needed.
Minorities, Immigrants and Otherwise

Anupam Chander's article Minorities, Shareholders and Otherwise 113 YALE L.J. 119 (2003), brilliantly offers a "conservative" justification for a U.S. constitutional law truly dedicated to fairness and justice for all. It does so through counter-intuitively looking to the bottom-line oriented world of corporate law. As Chander explains, modern constitutional law, which in effect ignores the racially discriminatory outcomes of facially neutral laws, has much to learn from corporate law, which strives to ensure fair outcomes - as well as procedures - for minority shareholders.This commentary offers a most powerful example of the gulf between constitutional law and corporate law identified by Professor Chander. Modern constitutional law affords no meaningful substantive protection to immigrants to the United States. The Supreme Court has consistently held that the political branches of the U.S. government possess "plenary power" over immigration and the courts lacks the power to review the substantive constitutionality of the immigration laws. The "plenary power" doctrine in operation serves as a bulwark of inequality for immigrants to the United States.
Implementing a Nuclear Materials Safety Management Program in the US and Russia

The United States and Russia are dismantling nuclear weapons and generating hundreds of tons of excess plutonium and high enriched uranium fissile nuclear materials that require disposition. The US Department of Energy and the Ministry of the Russian Federation for Atomic Energy (MINATOM) organizations are planning and implementing safe, secure storage and disposition operations for these materials in numerous facilities. This provides a new opportunity for technical exchanges between Russian and Western scientists that can establish an integrated and improved common safety culture for handling these materials. The development and use of personal relationships and joint projects among Russian and Western participants involved in fissile nuclear materials safety management contribute to improving nuclear materials nonproliferation and to making a safer world. Technical exchanges and workshops are being used to systematically identify opportunities in the nuclear fissile materials facilities to improve and ensure the safety of workers, the public, and the environment.
Natural History of Patients with Gastroparesis

Gastroparesis is a syndrome characterized by delayed gastric emptying in the absence of mechanical obstruction of the stomach. The three most common etiologies of gastroparesis are diabetes, postsurgical, and idiopathic (i.e., of unknown cause). Symptoms associated with gastroparesis include nausea, vomiting, postprandial fullness, early satiety, bloating, and/or abdominal pain. Asymptomatic cases of delayed gastric emptying can be seen; particularly, in diabetic patients where difficult to control glucoses can be associated with the onset of delayed gastric emptying. The true prevalence of gastroparesis is difficult to estimate due to the relatively poor correlation of symptoms with gastric emptying and the need to apply a diagnostic test to diagnose this condition in a community setting. It is unclear if the majority of patients with gastroparesis seek health care or how often they are referred to gastroenterologists, and therefore the true prevalence of gastroparesis is not known. Community studies of the outcome of gastroparesis are few, and studies conducted in tertiary referral centers may not reflect findings encountered in the general population. Estimates for the prevalence of gastroparesis have been approximately 4%, based on the prevalence of functional dyspepsia in the community (20%) and the prevalence of delayed gastric emptying in patients with functional dyspepsia (20%). However, in a recent epidemiologic study of Olmsted County, Minnesota, the prevalence of gastroparesis was lower with the prevalence of definite gastroparesis (symptomatic individual with delayed gastric emptying) reported to be 9.6 per 100,000 for men and 37.8 per 100,000 for women.
Qualitative Approach to Evaluating TR Definitions

The present research employed a qualitative strategy for soliciting practitioner interpretation of ATRA’s two most recent definitions of therapeutic recreation (TR) and supplemental statement of TR. We also sought practitioner definitions of TR based on their daily practice experiences. The study used a focus group comprised of a purposive sample of eight practitioners. We discovered five main ideas from independent reviews of the transcripts. Most subjects viewed TR as helpful but not conventional therapy. Reference to assessment seemed to stimulate discussion of its purpose and challenges among practitioners as well. The importance of the practitioner-patient relationship, the recreation environment, and enjoyment were emphasized in practitioner narratives. When asked to provide their own definitions, themes revolved around quality of life outcomes, such as reducing barriers, independence and functioning, wellness, and engaging life. Because of the purposive sampling in qualitative research, the findings cannot be generalized to a population of TR practitioners. Subscribe to TRJ
“PSYCH-PASS”: the Development, Adaptation, and Implementation of a Psychiatric Handoff

The primary purpose of the study was to develop and implement a psychiatry mnemonic PSYCH-PASS for transitions of care in residency training programs. The authors examined areas of improvement in the handoff system with residency training administration, service directors, and psychiatry residents to create PSYCH-PASS, a novel mnemonic that could be integrated in the electronic medical record (EMR). The components of PSYCH-PASS are Patient summary, Situational awareness, “whY” is the patient here, Comorbidities, Hemodynamics, Pharmacology/PRNs, Action list, Specifics, and Synthesis. The authors developed a 14 question pre- and post-survey with a 4-point Likert scale measuring five categories. Pre-survey and post-surveys completed by post-graduate year 2 and 3 residents at Montefiore Medical Center (n = 24) noted increased satisfaction, handoff efficiency, handoff efficiency, accessibility, accuracy, communication, awareness, and adherence to PSYCH-PASS, along with a decrease in frequency of errors. With promising results across a range of metrics indicating resident-reported positive impacts on patient care, further research on the implementation of PSYCH-PASS and its integration into EMR systems is merited. Future directions include gathering objective data from Epic and expansion of the initiative to other psychiatric services and institutions.
CSR Restatements and the Contagion Effect: An Experimental Investigation of Issue Materiality and Intent

Investors are demanding more Corporate Social Responsibility (CSR) reporting, which has increased the prevalence of CSR disclosures. However, such disclosures are restated at high rates, leading to concerns about reliability. Using two experiments, we investigate how investors react to restatements of CSR disclosures. Results reveal that a negative CSR restatement is decision useful, whereby investors are less willing to invest in a company that corrects a significant overstatement of performance. We also find that features of the environment—the materiality of the CSR issue and the intentionality of the error—affect investors’ reactions to the restatement. Finally, our study demonstrates how CSR restatements affect investment judgments. Specifically, we provide evidence of a “contagion effect,” by which the credibility effects of a CSR restatement transfer to investors’ assessments of financial disclosures. These results inform regulators and practitioners concerned about the ramifications of errors in CSR reporting on nonprofessional investors’ judgments.
Heat transfer in breaded and non-breaded chicken nuggets baked in a pilot-scale radiant wall oven

Abstract A pilot-scale radiant wall oven (RWO) was used for baking chicken nuggets, some breaded with different coatings, and also non-breaded. Overall and radiant heat transfer coefficients were calculated at the surface of nuggets based on the experimental temperature and heat flux measurements. The baking temperatures ranged between 347 °C and 407 °C with different processing times. The non-breaded nuggets had higher heat flux and the radiant heat transfer coefficients, 46897 ± 429 W/m2 and 151.1 W/m2K, than the breaded nuggets. Among the breaded nuggets, the corn flour breaded nuggets had higher heat transfer coefficient values than those of chickpea breaded because the corn flour has greater absorptivity for infrared radiation than that of chickpea flour. A correlation was found between the temperature and heat flux for non-breaded and corn breaded chicken nuggets.
Urban bumble bees are unaffected by the proportion of intensely developed land within urban environments of the industrial Midwestern USA

Urban environments have become an unexpected and promising avenue for pollinator conservation. One group of pollinators, bumble bees, might be especially well suited to utilize the heterogeneous landscape of urban ecosystems. Weedy margins (pervious land adjacent to impervious surfaces such as roads and paved lots) offer plentiful flowers for bees, but are often overlooked in urban pollinator studies. If weedy margins buffer urban bees from loss and fragmentation of foraging habitat in cities, then urban development may not have as strong of a negative effect on bumble bees as previously thought. In this study we test the hypothesis that bumble bee abundance and species richness in these weedy margins will not be affected by the degree of urbanization. We surveyed bees and flowers within weedy plots of land in six industrial cities of the Midwestern USA. Bumble bee abundance and richness were not influenced by the proportion of intensely developed land in the surrounding landscape, but abundance increased with local floral abundance. Bumble bees were also significantly more abundant than other bee groups (honeybees and ‘other’ wild bees). We found that weedy margins and weedy plant species provide important resources to urban pollinators, and to bumble bees in particular. If small patches of habitat can sustain bees in the city, future efforts of urban pollinator conservation could focus on the installation of high-quality micro-meadows, increasing the availability of quality habitat for pollinators.
Mating and parenting experiences sculpture mood-modulating effects of oxytocin-MCH signaling

The two hypothalamic neuropeptides oxytocin and melanin concentrating hormone (MCH) share several physiological actions such as the control of maternal care, sexual behavior, and emotions. In this study, we uncover the role for the oxytocin-MCH signaling pathway in mood regulation. We identify discrete effects of oxytocin-MCH signaling on depressive behavior and demonstrate that parenting and mating experiences shape these effects. We show that the selective deletion of OXT receptors from MCH neurons increases and decreases depressive behavior in sexually naive and late postpartum female mice respectively, with no effect on sexually naive male mice. We demonstrate that both parenting experience and mood-regulating effects of oxytocin-MCH are associated with synaptic plasticity in the reward and fear circuits revealed by the alterations of Arc expressions, which are associated with the depressive behavior. Finally, we uncover the sex-dependent effects of mating on depressive behavior; while the sexual activity reduces the basal levels of depressive behavior in male mice, it reduces in female mice evoked-depression only. We demonstrate that the oxytocin-MCH pathway mediates the effects of sexual activity on depressive behavior. Our data suggest that the oxytocin-MCH pathway can serve as a potential therapeutic target for the treatment of major depression and postpartum mood disorders.
A Non-zero Sum Power Control Game with Uncertainty

We consider the communication between a transmitter (user) and a receiver in the presence of a jammer where the jammer, in contrast to the user, has access to local information about jamming fading gain (reflecting distance of the jammer to the receiver) and jamming cost (reflecting its technical characteristics). The problem is modeled as a Bayesian game. Signal-to-interference-plus-noise ratio (SINR) is considered as user’s communication utility. Nash equilibrium as well as Stackelberg equilibrium are derived in closed form and compared.
Impact of cerebral venous sinus thrombosis associated with COVID-19.

Thromboembolism is one of the major complications of coronavirus disease 19 (COVID-19) [1]. Both arterial and venous thromboembolism involving various organs from COVID-19 related coagulopathy have been reported. While arterial ischemic strokes are common, cerebral venous sinus thrombosis (CVT) associated with COVID-19 has been increasingly recognized [2,3]. The true incidence of CVT in COVID-19 patients remains unknown. Various mechanisms of thromboembolism include elevated factor VIII, fibrinogen, D-dimer, prothrombotic microparticles like antiphospholipid antibodies, and inflammatory markers like C-reactive protein and interleukin-6 [4]. In this report, we aimed to determine the rates of CVT and its impact on outcomes in patients with COVID-19.
First market study in e-commerce food packaging: Resources, performance, and trends

Abstract Online grocery shopping is growing unprecedentedly around the globe. However, little is known about its packaging, which plays a key role from extending food shelf life to impacting the environment. This study aimed to characterize the e-commerce food packaging market to provide academia and industry with information to improve packaging for food shelf life extension and waste reduction. An online questionnaire focused on top selling liquid food products was developed and shared with consumer packaged goods (CPG) companies active in US e-commerce. The survey collected information on the packages sold in traditional or online grocery, including type, material, format, and defects (types and location). It also collected information on the future of online grocery packaging. The food categories with expected presence in e-commerce and the packaging changes required for e-commerce were identified. This study makes a noteworthy contribution to the packaging literature and can help decision-makers to improve packaging for online grocery.

A Machine Learning Algorithm Based on Supervised Clustering and Classification

In this paper a novel data mining technique - Clustering and Classification Algorithm-Supervised (CCA-S) is introduced. CCA-S supports incremental learning and non-hierarchical clustering, and is scalable for processing large data sets. CCA-S incorporates the class information in making clustering decisions, and uses the resulting clusters to classify new data records. We apply and test CCA-S on several common data sets for classification problems. The testing results show that the classification performance of CCAS is comparable to the other classification algorithms such as decision trees, artificial neural networks and discriminant analysis.
Studies on pollen and pollen extracts: XIV. The effects of varying hydrogen ion concentration upon the stability of pollen extracts

Abstract It has been shown that the presence of buffer salts in dextrose menstruum does not increase the potency of ragweed pollen extracts prepared with such solutions. Ragweed pollen extracts in isotonic dextrose buffered at either a slightly acid (hydrogen ion concentration 6.1) or slightly alkaline (hydrogen ion concentration 7.5) reaction have been shown to be at least as stable as similar unbuffered extracts. There is some indication that such buffering may increase stability. Alkaline buffer is probably to be preferred, as it prevents precipitation of the glucoside and thus prevents the development of a cloudy appearance on standing. Therapeutically, the same results were obtained with the extract buffered with sodium bicarbonate as with a similar unbuffered extract.
Sorting, Histogramming, and Other Statistical Operations on a Pyramid Machine

We define a pyramid machine to consist of an SIMD cellular array having pyramid interconnections, together with a controller consisting of a conventional microcomputer augmented with hardware to communicate with the cellular array. Primarily intended for graphics and image analysis applications, pyramid machines may also be used for more general data processing. Many operations can be performed in 0(log N) time with this architecture; finding maxima, areas, and centroids are typical of such operations. Here algorithms are given for sorting, for finding the kth largest element, for local order statistics, for median filtering of image data, for computing the histogram of a set of numbers, and for computing the mean and standard deviation. Most of these algorithms run as fast as or faster than the best known algorithms for any SISD or flat array SIMD computer. Others offer simpler programs than those for the optimal algorithms.
Recursive Total Least Squares: An Alternative to Using the Discrete Kalman Filter in Robot Navigation

In the robot navigation problem, noisy sensor data must be filtered to obtain the best estimate of the robot position. The discrete Kalman filter, commonly used for prediction and detection of signals in communication and control problems, has become a popular method to reduce the effect of uncertainty from the sensor data. However, in the domain of robot navigation, sensor readings are not only uncertain, but can also be relatively infrequent compared to traditional signal processing applications. In addition, a good initial estimate of location, critical for Kalman convergence, is often not available. Hence, there is a need for a filter that is capable of converging with a poor initial estimate and many fewer readings than the Kalman filter. To this end, we propose the use of a Recursive Total Least Squares Filter. This filter is easily updated to incorporate new sensor data, and in our experiments converged faster and to greater accuracy than the Kalman filter.
Mechanism of Action of β-Hydroxydecanoyl Thioester Dehydrase

Abstract Studies on the mechanism of the reversible enzymatic dehydration of d(-)-β-hydroxydecanoyl-N-acetylcysteamine to trans-2-decenoyl-N-acetylcysteamine and cis-3-decanoyl-N-acetylcysteamine are presented. They include determination of kinetic isotope effects with deuterium-labeled substrates and labeling experiments designed to follow the fates of the α- and γ-hydrogen atoms during the course of the reactions. The results show that trans-2-decenoyl-N-acetylcysteamine is formed directly by dehydration of β-hydroxydecanoate, whereas cis-3-decenoyl-N-acetylcysteamine arises only by isomerization of the conjugated enoate. The present findings, in conjunction with earlier kinetic data, lead to the conclusion that interconversion of the three substrates involves a common intermediate, presumably enzyme-bound α,β-decenoate.
Annotations enrich the virtual microscope slide experience (725.16)

PURPOSE: The uninitiated are often confused by the complexity of a histological specimen. And in the search for structures they are asked to identify, they may be so deterred by the task of locating and identifying structures they abandon the process for what they perceive to be easier ways of learning the organization of the organs and tissues. A solution may possibly lie in combining the virtues of a labeled atlas with the ease of viewing, panning and magnifying virtual slides (VS): at first, the users are guided to examples of the structures or features of organs they are to identify ensuring that nothing of importance is overlooked; and, with this introduction to the slide, the users can then explore the complexity of the VS by identifying structures on their own, with peers and/or with the assistance of an instructor while all the time being able to hide and show labels on the slide for reference purposes. METHODS: The VS are linked to LAYERS and LAYER REGIONS of the ANNOTATIONS box of the Aperio Ima...
Description, Classification, and Prediction of Dengue Illnesses in a Thai Pediatric Cohort: A Dissertation

Dengue fever (DF) and dengue hemorrhagic fever (DHF) are emerging infectious diseases which are endemic in many regions of the globe, many of which are resource-poor areas. DHF and DF impose a severe economic health burden in tropical and subtropical areas. Dengue virus causes an acute febrile illness that can be a self-limited febrile illness, as seen in most cases of DF, or a life-threatening illness with plasma leakage and shock, as seen in cases of DHF. A systematic review of the literature revealed gaps in the knowledge base of clinical laboratory findings of dengue illness with regards to longitudinal dynamics and classification and predictive modeling of disease severity. The objective of this thesis was to investigate the utility of clinical laboratory variables for classification and prediction of disease outcomes. The data used in this investigation was derived from a prospective study of Thai children presenting to either of two study hospitals within 72 hours of onset of an acute febrile illness. Systematic data collection, including clinical laboratory parameters, and routine clinical management continued each day until 24 hours after the fever had subsided. A final diagnosis of DHF, DF, or other febrile illness (OFI) was assigned by an expert physician after chart review. The first research objective of this study was to describe the temporal dynamics of clinical laboratory parameters among subjects with DHF, DF, or OFI. Data were analyzed using lowess curves and population-average models.
Detection and quantitative determination of glycine with pyridine and p-nitrobenzoyl chloride.

Glycine in quantities as small as 0.5 µg. can be detected as an orange-red color by a specific reaction with p-nitrobenzoyl chloride and pyridine. The procedure can be used both as a qualitative spot test and as a sensitive quantitative method. In a discussion of the reaction mechanism, it is suggested that the color is due to azlactone formation.
