Altering Educational Environments through Positive Peer Reporting: Prevention and Remediation of Social Problems Associated with Behavior Disorders.

Typical classroom management procedures designed to reduce instances of inappropriate social behavior (i.e., tattling and punishment systems) may adversely impact the social development and social relations of students with behavior and/or social emotional disorders. Two alternative procedures where students are encouraged to monitor and report incidental prosocial behaviors are described and research supporting their effectiveness in remedying and preventing social interaction problems within classroom environments are reviewed. Recommendations for future research on altering classroom environments so that peers encourage and support classmates' incidental prosocial behavior are provided. © 2002 Wiley Periodicals, Inc.
Randomized Controlled Trial of Mindfulness-Based Stress Reduction Versus Aerobic Exercise: Effects on the Self-Referential Brain Network in Social Anxiety Disorder

Background: Social Anxiety Disorder (SAD) is characterized by distorted self-views. The goal of this study was to examine whether Mindfulness-Based Stress Reduction (MBSR) alters behavioral and brain measures of negative and positive self-views. Methods: 56 adult patients with generalized SAD were randomly assigned to MBSR or a comparison aerobic exercise (AE) program. A self-referential encoding task was administered at baseline and post-intervention to examine changes in behavioral and neural responses in the self-referential brain network during functional magnetic resonance imaging. Patients were cued to decide whether positive and negative social trait adjectives were self-descriptive or in upper case font. Results: Behaviorally, compared to AE, MBSR produced greater decreases in negative self-views, and equivalent increases in positive self-views. Neurally, during negative self vs. case, compared to AE, MBSR led to increased brain responses in the posterior cingulate cortex (PCC). There were no differential changes for positive self vs. case. Secondary analyses showed that changes in endorsement of negative and positive self-views were associated with decreased social anxiety symptom severity for MBSR, but not AE. Additionally, MBSR-related increases in DMPFC activity during negative self-view vs. case were associated with decreased social anxiety-related disability and increased mindfulness. Analysis of neural temporal dynamics revealed MBSR-related changes in the timing of neural responses in the DMPFC and PCC for negative self-view vs. case. Conclusions: These findings suggest that MBSR attenuates maladaptive habitual self-views by facilitating automatic (i.e., uninstructed) recruitment of cognitive and attention regulation neural networks. This highlights potentially important links between self-referential and cognitive-attention regulation systems and suggests that MBSR may enhance more adaptive social self-referential processes in patients with SAD
Patella Baja After Knee Arthroplasty Surgery. Is It Really Patella Baja

Patella baja compromises the mechanics of a prosthetic knee and complicates eversion of the extensor mechanism during revision surgery. The lowering of the patella, however, may be illusionary. Narrowing of the space between the patella and the tibia may be not due to shortening of the patellar tendon, but due to a raised joint line. This condition is perhaps more appropriately called "pseudo patella baja" or "tibia alta". The treatment of true patella baja must be directed towards the patellar tendon, while the treatment of tibia alta (when necessary) requires revision of the femoral and tibial implant. The height of the patella is generally judged by its distance from the tibia. Certain indices use the tibial plateau as the tibial reference, while other methods reference off the tibial tuberosity. If the prosthetic joint line is raised, the indices that reference off the tibial plateau will suggest patella baja, even if the patella lies in a normal position relative to the femoral trochlea. However, the ratios based on the tibial tuberosity will remain normal. When evaluating patellar height in a prosthetic knee, we recommend using both categories of parameters to differentiate between patella baja and tibia alta.
Characterization of a Rac1- and RhoGDI-Associated Lipid Kinase Signaling Complex

Rho family GTPases regulate a number of cellular processes, including actin cytoskeletal organization, cellular proliferation, and NADPH oxidase activation. The mechanisms by which these G proteins mediate their effects are unclear, although a number of downstream targets have been identified. The interaction of most of these target proteins with Rho GTPases is GTP dependent and requires the effector domain. The activation of the NADPH oxidase also depends on the C terminus of Rac, but no effector molecules that bind to this region have yet been identified. We previously showed that Rac interacts with a type I phosphatidylinositol-4-phosphate (PtdInsP) 5-kinase, independent of GTP. Here we report the identification of a diacylglycerol kinase (DGK) which also associates with both GTP- and GDP-bound Rac1. In vitro binding analysis using chimeric proteins, peptides, and a truncation mutant demonstrated that the C terminus of Rac is necessary and sufficient for binding to both lipid kinases. The Rac-associated PtdInsP 5-kinase and DGK copurify by liquid chromatography, suggesting that they bind as a complex to Rac. RhoGDI also associates with this lipid kinase complex both in vivo and in vitro, primarily via its interaction with Rac. The interaction between Rac and the lipid kinases was enhanced by specific phospholipids, indicating a possible mechanism of regulation in vivo. Given that the products of the PtdInsP 5-kinase and the DGK have been implicated in several Rac-regulated processes, and they bind to the Rac C terminus, these lipid kinases may play important roles in Rac activation of the NADPH oxidase, actin polymerization, and other signaling pathways.
Comparison of two methods of future liver remnant volume measurement

In liver transplantation, a minimum graft to patient body weight (BW) ratio is required for graft survival; in liver resection, total liver volume (TLV) calculated from body surface area (BSA) is used to determine the future liver remnant (FLR) volume needed for safe hepatic resection. These two methods of estimating liver volume have not previously been compared. The purpose of this study was to compare FLR volumes standardized to BW versus BSA and to assess their utility in predicting postoperative hepatic dysfunction after hepatic resection. Records were reviewed of 68 consecutive noncirrhotic patients who underwent major hepatectomy after portal vein embolization between 1998 and 2006. FLR (cubic centimeter) was measured preoperatively with three-dimensional helical computed tomography; TLV (cubic centimeter) was calculated from the patients’ BSA. The relationship between FLR/TLV and FLR/BW (cubic centimeter per kilogram) was examined using linear regression analysis. Receiver operating characteristic (ROC) curve analysis was used to determine FLR/TLV and FLR/BW cutoff values for predicting postoperative hepatic dysfunction (defined as peak bilirubin level > 3 mg/dl or prothrombin time > 18 s). Regression analysis revealed that the FLR/TLV and FLR/BW ratios were highly correlated (Pearson correlation coefficient, 0.98). The area under the ROC curve was 0.85 for FLR/TLV and 0.84 for FLR/BW (95% confidence interval, 0.71–0.97). Sixteen of the 68 patients developed postoperative hepatic dysfunction. The ROC curve analysis yielded a cutoff FLR/BW value of ≤0.4, which had a positive predictive value (PPV) of 78% and a negative predictive value (NPV) of 85%. The corresponding FLR/TLV cutoff value of ≤20% had a PPV of 80% and a NPV of 86%. Based on the strong correlation between the FLR measurements standardized to BW and BSA and their similar ability to predict postoperative hepatic dysfunction, both methods are appropriate for assessing liver volume. In noncirrhotic patients, a FLR/BW ratio of ≤0.4 and FLR/TLV of ≤20% provide equivalent thresholds for performing safe hepatic resection.
Sigmoid profiled septum: Evaluation of the parabolic reflector with the septum feed horn

A sigmoid function is used to define a smooth profile for possible use in septum designs. In addition, Particle Swarm Optimization (PSO) is used to optimize the sigmoid-profiled septum polarizer. PSO is applied to a sigmoid septum as well as a stepped septum, and the performance of both designs is further compared. Both septum designs are selected to be optimized for a 25% bandwidth, and the impedance matching and axial ratio is analyzed. Furthermore, the reflector antenna system is investigated utilizing the optimized septum horns as a feed for a 15λ parabolic reflector antenna. A directivity of approximately 32 dB is attained for both parabolic reflector antenna systems.
Invariants on demand

The last decade has displayed a trend for automatic reasoning techniques to operate on demand. Examples of this trend are counterexample-driven predicate refinement, as used in software model checking, and lemmas on demand, as used in automatic theorem proving. In line with this trend, the author shows a technique that combines abstract interpretation and theorem proving, inferring program invariants when the theorem prover cannot proceed without them. This is joint work with Francesco Logozzo. To motivate the technique, the talk also includes a demo of the Spec# programming system, which makes use of loop-invariant inference, verification-condition generation, and automatic theorem proving to reason about object-oriented programs.
A Note on the Consumer Benefits of Information

Two recent articles in this Journal provide contradictory findings on the benefits of consumer information. Brenda J. Cude tried a variety of measures of benefit, none of which appears as systematic as Scott Maynes’ distance from the efficiency frontier, but all of which suggest very large gains from better information. Experimental studies by Merle D. Faminow and Bruce L. Benson, on the other hand, suggest that posted prices lead to higher average prices and profits, presumably by allowing signalling among sellers and reducing their uncertainty.2 I suggest that both findings are misleading if not incorrect. The experiments were in a duopoly framework where implicit collusion is relatively easy to induce and in a product area where margins are small anyway. Perhaps hidden-price-discounting sometimes persists more than advertised bargains, but experiments with a greater number of sellers would be more persuasive. None of the Cude estimates of the benefits from best buys is so neatly quantitative as adding the departures from a Maynes efficiency frontier, since that might be thought of as the aggregate benefit. My problem is identifying from whence these benefits are to come. The average profit level in retailing is far below any of these estimates. Are there other monopoly rents that can be captured? Surely not in the rented space of the retailers, since other kinds of businesses compete for that space. Can one describe a process by which a new equilibrium is established with lower consumer prices? Does one drive out half the retailers and double the volume of the
The Involvement of the Inferior Parietal Cortex in the Numerical Stroop Effect and the Distance Effect in a Two-digit Number Comparison Task

The neural mechanism of number representation and processing is currently under extensive investigation. In this functional magnetic resonance imaging study, we designed a number comparison task to examine how people represent and compare two-digit numbers in the brain, and whether they process the decade and unit digits in parallel. We manipulated the decade-unit-digit congruency and numerical distance between the pairs of numbers. We observed both Stroop-like interference and the distance effect in the participants' performance. People responded more slowly to incongruent pairs of numbers and pairs of a smaller distance. The inferior parietal cortex showed common and distinct patterns of activation for both attentional selection and number comparison processes, and its activity was modulated by the Stroop-like interference effect and the distance effect. Taken together, these results support both parallel and holistic comparison of two-digit numbers in the brain.
Rates of protein synthesis by hepatocytes isolated from rats of various ages

The rate of total protein synthesis in isolated hepatocytes was determined. The incorporation of L-[3H]valine into protein is linear for at least two hours of incubation and is affected by the concentration of amino acids in the medium. Uptake of valine by hepatocytes from 1.5- and 18-month-old rats was identical and appears to occur by simple passive diffusion. Within five minutes, the specific activities of the intracellular and extracellular valine pools are equivalent. The specific activities of these pools are saturated by 1.6 mM valine and remain constant for 60 minutes of incubation. The rates of protein synthesis by hepatocytes from 1- to 2-month-old rats is 96.8 pmoles of valine per minute per milligram protein. This is comparable to rates of protein synthesis reported for perfused liver and liver in vivo and is approximately 64% higher than the rate of protein synthesis by hepatocytes from 18-month-old rats.
Lack of hepcidin expression attenuates steatosis and causes fibrosis in the liver

CONCLUSION: Lack of hepcidin expression inhibits hepatic lipid accumulation and induces early development of fibrosis following high fat intake. Hepcidin and iron may play a role in the regulation of metabolic pathways in the liver, which has implications for NAFLD pathogenesis.
Ethics: Holy Evil and Theocracy

This article discusses how the concept of holiness can provide a strong source of legitimation and direction for governments. It examines how religion develops from very early conceptions of the holy and how holy people gain a privileged moral and political authority. This authority has historically been either co-opted or used by the clerical class to affect the legitimacy of the governing regime. The paper examines three models by which theocracy develops where the moral authority of the revelation of the Holy becomes embodied in religion. Religion and the clerical class then develop multiple ways to control the state government either indirectly through control of appointment and rhetoric, direct rule by the clerical class or using control over legitimacy to control government indirectly.
The Federal Judicial Conduct and Disability System: Unfinished Business for Congress and for the Judiciary

For most of the nation’s history, the only formal mechanism for dealing with misconduct by federal judges was the cumbersome process of impeachment. That era ended with the enactment of the Judicial Councils Reform and Judicial Conduct and Disability Act of 1980 (1980 Act or Act). In 2002, Congress made modest amendments to the Act and codified the provisions in Chapter 16 of Title 28. In 2008, the Judicial Conference of the United States – the administrative policy-making body of the federal judiciary – approved the first set of nationally binding rules for misconduct proceedings. Under the 1980 Act and the 2008 Rules, complaints of misconduct by federal judges are handled under a system that has aptly been described as one of “decentralized self-regulation.” That system is sound and does not require fundamental restructuring. At the same time, the experience of the past few years has revealed gaps and deficiencies in the regulatory regime that warrant attention. Some may be appropriately dealt with through revision of the judiciary’s 2008 Rules, but others should be addressed by Congress through changes to Chapter 16. In this statement, submitted at a hearing of the House Judiciary Committee, the author suggests statutory amendments dealing with three aspects of the system: transparency and disclosure; disqualification of judges; and review of orders issued by chief judges and judicial councils. In each of these areas, the judiciary has promulgated rules that reflect sound policy but are in conflict or tension with statutory language. Moreover, these elements are more than procedural; they determine who makes the decisions and how much information the public receives. The author also suggests several steps that can be taken by the Judicial Conference without any further authorization by Congress. By implementing these suggestions, Congress and the judiciary can update Chapter 16 and the misconduct rules to reflect the best practices developed by the Judicial Conference and by individual judges over the years. The statement is followed by an Appendix that includes transcripts of oral colloquies at the hearing as well as the author’s response to a written question from a member of the Judiciary Committee.
Quality Control Aspects of the Chemistry Laboratory Form

Quality control in the clinical laboratory encompasses more than the precise measurement of a value from a specimen received in the laboratory. I t involves accuracy of requesting the specimen, obtaining it from the correct patient, and accurate reporting of the results. Ideally there should be means of rechecking calculations and the information accumulated during the collection and examination of a specimen, such as an optical density reading, gross appearance of the specimen, and time and date of collection of the specimen. Effort in quality control has principally been directed toward methods of insuring precision and accuracy of testing within the laboratory, with aids such as commercial quality control sera, quality control pools, and quality control charts. There have been efforts directed toward automatic data processing to impove reporting and data handling, but these approaches are still impractical for the average laboratory. There is need for quality control in requisition, data recording, and reporting, however, and for the average laboratory this revolves largely around the laboratory form. It is the purpose of this report to analyze laboratory forms in widespread current use and to present a laboratory report form system which eliminates recopying. We consider the system to be useful for both large and small hospitals as a manual approach to communication and data processing. The laboratory form is designed so that it can serve as a source document for keypunch or other automatic data handling operations, as all of the information is coded digitally.

Evolution and advances in laparoscopic ventral and incisional hernia repair

Primary ventral hernias and ventral incisional hernias have been a challenge for surgeons throughout the ages. In the current era, incisional hernias have increased in prevalence due to the very high number of laparotomies performed in the 20(th) century. Even though minimally invasive surgery and hernia repair have evolved rapidly, general surgeons have yet to develop the ideal, standardized method that adequately decreases common postoperative complications, such as wound failure, hernia recurrence and pain. The evolution of laparoscopy and ventral hernia repair will be reviewed, from the rectoscopy of the 4(th) century to the advent of laparoscopy, from suture repair to the evolution of mesh reinforcement. The nuances of minimally invasive ventral and incisional hernia repair will be summarized, from preoperative considerations to variations in intraoperative practice. New techniques have become increasingly popular, such as primary defect closure, retrorectus mesh placement, and concomitant component separation. The advent of robotics has made some of these repairs more feasible, but only time and well-designed clinical studies will tell if this will be a durable modality for ventral and incisional hernia repair.
Eastern tropical Pacific vegetation response to rapid climate change and sea level rise: A new pollen record from the Gulf of Tehuantepec, southern Mexico

Abstract A 30,000-year-long pollen record from the Gulf of Tehuantepec, southern Mexico shows the varying influence of air temperature, precipitation and eustatic sea-level rise on changes in coastal and upland vegetation patterns. During the late-glacial period, pine-juniper forests grew in the Sierra Madre del Sur along the Pacific Slope with broadleaf forests present at low elevations. Coastal wetland and riparian vegetation were limited in distribution. Significant cooling associated with Heinrich 1 (17,000–15,000 cal yr BP) resulted in an expansion of pine-juniper woodland. By the time of Bolling-Allerod warming (14,700–13,000 cal yr BP), extensive mangrove forest development was assisted by sea-level rise and reduced precipitation associated with a more southerly position of the Intertropical Convergence Zone (ITCZ) than at present. Concurrently, the expansion of oak into pine woodlands was promoted by warmer conditions than before. Increased summer precipitation in the early Holocene and stabilizing sea levels limited mangrove forests along the coast and allowed mixed conifer and hardwood forest to become more widespread inland. The onset of a more seasonal climate, driven by a weakening of the Mexican monsoon and a southerly shift in ITCZ position led to the establishment of modern open forests of pine and oak after 4300 cal yr BP.
Pharmacologic Tests of a Role for Acetylcholinesterase in Promoting Neurite Outgrowth by Dorsal Root Ganglia

Possible “non classical” roles for acetylcholinesterase (AChE) have attracted attention because of the enzyme’s widespread distribution and striking ontogenetic regulation, with bursts of expression that coincide in space and time with neurite outgrowth and axonal elongation in developing avian and mammalian nervous systems (1,2). Other indications that AChE may be involved in neuronal differentiation include: sequence homology between AChE and cell-adhesion molecules like gliotactin and neuroligin-1 (3); promotion of neurite outgrowth from sympathetic neurons cultured on substrates of purified AChE (4); and growth-inhibitory effects of selected cholinesterase inhibitors (5).
Cervical Cancer Screening and the Immunosuppressed Patient: the Issues in Screening High-Risk Populations

While evidence-based guidelines are available for cervical cancer screening in the general population, women at higher risk of persistent HPV infection and cervical cancer are excluded. There is limited evidence to guide screening practices for “high-risk” women, in particular, those who are immunosuppressed. Women with immunosuppression demonstrate an increased risk of cervical dysplasia and invasive cervical cancer (ICC) compared to the baseline population. Women with HIV were found to have increased rates of ICC and recurrent dysplasia, compounded by lower CD4 counts. Women with other forms of immune suppression demonstrated variable risk of dysplasia and cancer with the highest risk in transplant recipients and variable risk of dysplasia reported in autoimmune diseases. Data support updated screening guidelines for women with HIV: annual cytology for 3 years, and if screening is negative, increased screening intervals to every 3 years. However, women with HIV and other forms of immunosuppression have been reported to be less compliant with screening guidelines. While there is high-quality data to support screening intervals for women with HIV, we were not able to identify data to guide modality and interval of screening in other types of immune compromise. Compliance with screening is lower both in women with HIV and other immune-mediated disease. Improving screening compliance in this high-risk population with a simplified screening strategy is likely the most important factor for reducing the risk of cervical cancer and further research is needed.
Transthoracic Echocardiography: Pitfalls and Limitations as Delineated at Cardiac CT and MR Imaging

Transthoracic echocardiography ( TTE transthoracic echocardiography ) is a critical tool in the field of clinical cardiology. It often serves as one of the first-line imaging modalities in the evaluation of cardiac disease owing to its low cost, portability, widespread availability, lack of ionizing radiation, and ability to evaluate both anatomy and function of the heart. Consequently, a large majority of patients undergoing a cardiac computed tomography (CT) or magnetic resonance (MR) imaging examination will have a TTE transthoracic echocardiography available for review. Therefore, it is imperative that cardiac imagers be familiar with the fundamentals of a routine TTE transthoracic echocardiography examination and common TTE transthoracic echocardiography pitfalls and limitations that may lead to a referral for cardiac CT or MR imaging. The four standard TTE transthoracic echocardiography windows and their corresponding views will be discussed and the relevant anatomy highlighted. Common pitfalls and limitations of TTE transthoracic echocardiography will be highlighted using cardiac CT and MR imaging as the problem-solving modality. In this article, we have categorized the relevant pitfalls and limitations of TTE transthoracic echocardiography into four broad categories: (a) masses and mass mimics (crista terminalis, eustachian valve, right ventricle moderator band, atrioventricular groove fat, left ventricular band [or left ventricular false tendon], hiatal hernia, caseous calcification of the mitral annulus, lipomatous hypertrophy of the interatrial septum, cardiac tumors), (b) poorly visualized apical lesions (aneurysm, thrombus, infarct, and hypertrophic and other nonischemic cardiomyopathies), (c) evaluation for ascending thoracic aortic dissections (false positive, false negative, dissecting aneurysms), and (d) pericardial disease (acute and chronic/constrictive pericarditis, pericardial tamponade, pericardial cysts and diverticula, congenital absence of the pericardium).

The Top-of-Instrument corrections for nuclei with AMS on the Space Station

Abstract The Alpha Magnetic Spectrometer (AMS) is a large acceptance, high precision magnetic spectrometer on the International Space Station (ISS). The top-of-instrument correction for nuclei flux measurements with AMS accounts for backgrounds due to the fragmentation of nuclei with higher charge. Upon entry in the detector, nuclei may interact with AMS materials and split into fragments of lower charge based on their cross-section. The redundancy of charge measurements along the particle trajectory with AMS allows for the determination of inelastic interactions and for the selection of high purity nuclei samples with small uncertainties. The top-of-instrument corrections for nuclei with 2 Z ≤ 6 are presented.

Contract grading in the technical writing classroom: Blending community-based assessment and self-assessment

Abstract This article builds from the author’s previously published article, “Contract Grading in a Technical Writing Classroom: A Case Study”. This prior study examined how students in a technical writing classroom collaborated to generate criteria relating to the quality of their writing assignments with the instructor determining whether or not they met this criteria. This study demonstrated that although students perceived more involvement in the grading process, they resisted participation in crafting criteria as a class and preferred traditional grading methods by an expert. Based on feedback from reviewers and additional reflection, this IRB approved study consists of a revised contract grading system implemented in my spring 2017 technical writing classroom. This contract grading system consists of full student involvement throughout the contract grading process, which includes generating classroom-agreed upon criteria for each assignment and self-assessment of each assignment. The results from this study show that students embraced being involved with all aspects of their assessment, specifically in generating criteria and having clear expectations and more autonomy. The study concludes with additional implications and encouragement to continue to experiment with contract grading.
Chapter 7 Axis Formation and the Rapid Evolutionary Transformation of Larval Form

Abstract Marine invertebrate embryos and larvae are diverse and can evolve rapidly, providing a link between early developmental and evolutionary mechanisms. We here discuss the role of evolutionary changes in axis formation, which is a crucial part of the patterning of marine embryos and larvae. We focus on sea urchin embryos, where axial features are well defined and subject to active current investigation. The genetic control of processes of formation of the three axial systems, animal–vegetal, dorsal–ventral, and left–right, is becoming established for species that undergo development via the feeding pluteus larva. These species represent the primitive condition among living sea urchins. We compare their developmental processes to the highly modified development of a species that has evolved a nonfeeding larva. This derived form has accelerated some elements of axis formation, and eliminated or modified others. Three features of embryonic/larval evolution stand out (1) evolution of developmental features occurs rapidly over geological time; (2) upstream gene regulatory systems of axis formation are conserved, whereas downstream features evolve rapidly; and (3) heterochronies play an important role.
Successful heart‐kidney transplantation from a Hepatitis C viremic donor to negative recipient: One year of follow‐up

Every year the number of patients waiting for a heart transplant increases faster than the number of available donor organs. Some potential donor organs are from donors with active communicable diseases, including hepatitis C virus (HCV), potentially making donation prohibitive. The advent of direct-acting antiviral agents for HCV has drastically changed the treatment of HCV. Recently, these agents have been used to treat HCV in organ donor recipients who acquired the disease from the donor organ. We report a case of heart-kidney transplantation from an HCV viremic donor to HCV negative recipient with successful treatment and sustained virologic response.
Automated Intelligent Systems for Secure Live Migration

Cloud computing provides on-demand computing and storage services with high performance and high scalability. In this paper, we first introduce an energy-aware framework for task scheduling and resource scheduling in virtual clusters by creating a number of clusters based on the workload. While virtual machine migration is critical for load balancing, consolidation and server maintenance in virtualized datacenters, it can also increase security risks. Alternatively one should encrypt the migration traffic, while eliminating the need for dedicated control networks, but provide data security and mutual authentication. Currently a few techniques have been proposed to secure the virtual machine migration process. This research paper helps in securing the data without affecting the original data and protecting the data. The architecture proposed in this paper helps in providing an automated intelligent system that monitors for overload or underload and decides when live migration has to take place. Once the VM is selected, encryption is done using a suitable security algorithm and hence the data security, mutual authentication, confidentiality and integrity is achieved. It has been observed that the use of AES reduces the cost and time to encrypt the data and hence we use this efficient algorithm to secure our data. Due to the use of automated monitoring and use of efficient algorithms for clustering and encryption, the total cost and time for the entire process has been reduced and a comparative performance analysis is also demonstrated in this paper.

Wave Optics Simulation Studies of the Fried Parameter for Weak to Strong Atmospheric Turbulent Fluctuations

Wave optics simulations are conducted for modeling the long exposure point spread function through atmospheric turbulence. The results indicate that analytic expressions for the Fried parameter are accurate even in the strong turbulence fluctuation regime.
Towards Generalizable Distance Estimation By Leveraging Graph Information

Approximating the distance of objects present in an image remains an important problem for computer vision applications. Current SOTA methods rely on formulating this problem to convenience depth estimation at every pixel; however, there are limitations that make such solutions non-generalizable (i.e varying focal length). To address this issue, we propose reformulating distance approximation to a per-object detection problem and leveraging graph information extracted from the image to potentially achieve better generalizability on data acquired at multiple focal lengths.
RNA-binding protein altered expression and mislocalization in MS.

Objective To determine whether there are nuclear depletion and cellular mislocalization of RNA-binding proteins (RBPs) transactivation response DNA-binding protein of 43 kDa (TDP-43), fused in sarcoma (FUS), and polypyrimidine tract–binding protein (PTB) in MS, as is the case in amyotrophic lateral sclerosis (ALS) and oligodendrocytes infected with Theiler murine encephalomyelitis virus (TMEV), we examined MS lesions and in vitro cultured primary human brain–derived oligodendrocytes. Methods Nuclear depletion and mislocalization of TDP-43, FUS, and PTB are thought to contribute to the pathogenesis of ALS and TMEV demyelination. The latter findings prompted us to investigate these RBPs in the demyelinated lesions of MS and in in vitro cultured human brain–derived oligodendrocytes under metabolic stress conditions. Results We found (1) mislocalized TDP-43 in oligodendrocytes in active lesions in some patients with MS; (2) decreased PTB1 expression in oligodendrocytes in mixed active/inactive demyelinating lesions; (3) decreased nuclear expression of PTB2 in neurons in cortical demyelinating lesions; and (4) nuclear depletion of TDP-43 in oligodendrocytes under metabolic stress induced by low glucose/low nutrient conditions compared with optimal culture conditions. Conclusion TDP-43 has been found to have a key role in oligodendrocyte function and viability, whereas PTB is important in neuronal differentiation, suggesting that altered expression and mislocalization of these RBPs in MS lesions may contribute to the pathogenesis of demyelination and neurodegeneration. Our findings also identify nucleocytoplasmic transport as a target for treatment.
Reflections of a COVID-19 Graduate Nurse Student.

In the midst of pandemic and chaos, the world did not cease. Although shelter-in-place was mandated, advance practice nursing students did not waiver. The Class of 2021 advance practice nurses will enter preventive and tertiary care with patience and resiliency. While healthcare facilities were limiting non-essential staff and visitors, the Class of 2021 did not stop. While working as full-time nurses and preparing our families for the worse care scenarios, we did not deter from our goals. Rather we found new goals through reflection and will be better prepared to face the unknown.
Potassium citrate-assisted eco-friendly synthesis of tannin-derived nitrogen-doped micro–mesoporous carbon microspheres

Nitrogen-doped micro–mesoporous carbon microspheres (N-MMCSs) were successfully synthesized using condensed tannins in place of synthetic phenolic compounds as carbon precursors. Such N-MMCSs were fabricated using a modified one-pot Stober method in the presence of Pluronic F127 and potassium citrate which act as a structure-directing agent and an alternative activating agent, respectively. In addition to using tannins instead of synthetic phenolic resin precursors, lysine was employed as both a base catalyst and nitrogen source in lieu of toxic ammonia, further demonstrating a green synthesis. The development of porosity in N-MMCSs was achieved by varying the amount of potassium citrate added to the reaction. The resulting polymer spheres with incorporated potassium salts and nitrogen species were simultaneously carbonized and activated at 800 °C. This strategy affords activated N-MMCSs having high specific surface area, micropore volume, and mesopore volume up to 971 m2/g, 0.38 cm3/g, and 0.27 cm3/g, respectively with the retention of spherical morphology, mesoporous structure, and the presence of nitrogen species that results in high CO2 uptakes at ambient temperatures. This work opens a new avenue in the synthesis of carbon spheres with tunable porosity to meet the specific requirement of given applications.
Virtual farmers markets: A reflective essay on a rural Ohio project

This reflective essay discusses the development, structure, operation, and transitioning of an online virtual farmers market in rural Ohio. In this model, customers order online and then pick up their fresh, local produce at a specified time and loca­tion. Through a combination of practitioner expe­rience in the market’s development and informal discussions with people associated with the mar­ket’s development and management, the authors analyze the positive and negative aspects of the online market structure and implementation, as well as suggest critical steps that may be necessary to export this model to other communities. They also consider potential structural and process improvements that could increase viability and success. A last-minute addendum briefly discusses the potential for this model to become a meaning­ful response to the COVID-19 issue as well.
Magnesium and imidazole propionate

Summary Background & aims Circulating levels of imidazole propionate (ImP), a microbial metabolite of histidine, were higher in participants with type 2 diabetes (T2D) compared to those without and also induced insulin resistance. We hypothesize that low intake of magnesium (Mg) and/or low body Mg status in humans may lead to low Mg concentrations in gut microbiota, and, in turn, elevated microbial production of ImP and increased levels of circulating ImP. Methods We tested this hypothesis in the Personalized Prevention of Colorectal Cancer Trial (PPCCT) (registered at clinicaltrials.gov as NCT01105169), a double-blind 2 × 2 factorial randomized controlled trial enrolling 240 participants at high risk of Mg deficiency. Among 68 participants (34 each in the treatment and placebo arms), we measured plasma metabolites using the untargeted Metabolon's global Precision Metabolomics™ LC-MS platform. Results Mg treatment significantly reduced ImP by 39.9% compared to a 6.0% increase in the placebo arm (P = 0.02). We found the correlation coefficients were −0.12 (P = 0.32) and −0.31 (P Conclusions Further studies are needed to replicate these findings and to investigate whether Mg treatment specifically changes the production of ImP by microbiota. Also, future studies are warranted to confirm the effect of Mg treatment on glutarate and InP.
Touch at a distance: toward a phenomenology of film

“We cannot open our eyes to things without distancing ourselves from what we seek. Separation is the price of vision” (de Certeau in Enclitic 7: 24–31, 1983). Yet, what happens when what we see at a distance grabs us, touches us, drawing us closer (Blanchot 1981)? Is this not the experience of film? In this article I argue that modulating distance lies at the heart of perception and filmmaking, palpable tensions in moving closer-to (proximal) and distancing-from (distal) bodies and things, entangling senses across the sensorium in what is called haptic perception and, by extension, haptic cinema. I explore modulation in distancing in revisiting Vittorio De Sica’s Italian neorealist film, Umberto D., a film customarily discussed in optical-ocular terms. En route we experience De Sica’s artistry in conveying ‘instants in life’ and ‘spectral distancing’ and we have a visitation with Agamben’s (2000) gestural cinema which exposes the mediality of film, opening up haptic-ethical thought and expression. In the final section I push toward a phenomenology of film inspired by Merleau-Ponty’s (1968) reversibility in perception and Morris’s (2002) associated ideas of tactile resonance and reverberation. I articulate a phenomenology of filmic-body couplings as lived moments in touch that resonate, reverberate and linger as affective intensities, taking cinema beyond the theater, screen, spectator, image, and representational logics.
Chapter 9 Minerals and Agriculture

Publisher Summary Modern agriculture depends upon man's ability to cycle minerals that are nutritionally important, through crops, poultry, and animals. In particular, the absorption of these minerals by green plants and their subsequent role in the formation of organic compounds is basic to almost all forms of life. This chapter describes the natural inputs of minerals to agricultural soils that includes atmospheric additions, precipitation, and recent alluvial deposits. Statistics on plant nutrient consumption are generally limited to the three major nutrients N, P, and K. Mineral deposits of N are limited largely to NaNO 3 —one of the oldest N fertilizers used—and very small amounts of KNO 3 . Potassium (K), often referred to as potash (K 2 O), is required by plants in large quantities because it is essential to the complex biochemistry of plant growth. Cropping, leaching, volatilization, and erosion are the four principal pathways the ability of man to maintain a favorable equilibrium between losses and gains of available plant nutrients in agricultural soils. Man's struggle to maintain this equilibrium has existed since agriculture began.
Three Myths for Aging Copyrights: Tithonus, Dorian Gray, Ulysses

Copyrights have the capacity to grow exceedingly old. Indeed, they have no other choice. In many countries, including the United States, if a writer completes her first novel at the age of thirty and lives to be eighty, that novel will automatically enjoy a total copyright term of 120 years, with no requirement that the author or her heirs renew or otherwise maintain the copyright along the way. In the United States, corporate-owned works as well as many older works published before 1978 enjoy a copyright term of 95 years from the year of first publication, again without any maintenance requirements. The result of all this legislative largesse is compulsory old age for copyrights. As an exercise in awareness, this Article proposes that we think of copyrights as living creatures inhabiting time, keenly conscious of the long life dictated for them by forces beyond their control. By such a trick of personification, we can begin to understand the problem of aging copyrights, for copyrights have an organic aspect that varies according to the length of protection they provide, the qualities of the works they protect, and the behavior of copyright owners. This Article imagines copyrights under figures drawn from myth and literature — Tithonus and Dorian Gray — who exemplify the perils of defying the natural aging process. The Article also discusses the copyrights in the works of the famous Irish author James Joyce (1882–1941) — including his novel Ulysses (1922) — which, along with the behavior of Joyce’s literary estate in recent decades, offer a vivid illustration of the problem of prolonged copyrights in a changing culture. The Article concludes by offering another Ulysses — not Joyce’s novel, but Homer’s legendary Greek king and warrior — as a normative model for a rational copyright law that would accept the aging and death of exclusive rights as part of the cycle of creative life, and more wisely balance the interests of copyright owners and the public.
