Enabling SIP-based sessions in ad hoc networks

The deployment of infrastructure-less ad hoc networks is suffering from the lack of applications in spite of active research over a decade. This problem can be solved to a certain extent by porting successful legacy Internet applications and protocols to the ad hoc network domain. Session Initiation Protocol (SIP) is designed to provide the signaling support for multimedia applications such as Internet telephony, Instant Messaging, Presence etc. SIP relies on the infrastructure of the Internet and an overlay of centralized SIP servers to enable the SIP endpoints discover each other and establish a session by exchanging SIP messages. However, such an infrastructure is unavailable in ad hoc networks. In this paper, we propose two approaches to solve this problem and enable SIP-based session setup in ad hoc networks (i) a loosely coupled approach, where the SIP endpoint discovery is decoupled from the routing procedure and (ii) a tightly coupled approach, which integrates the endpoint discovery with a fully distributed cluster based routing protocol that builds a virtual topology for efficient routing. Simulation experiments show that the tightly coupled approach performs better for (relatively) static multihop wireless networks than the loosely coupled approach in terms of the latency in SIP session setup. The loosely coupled approach, on the other hand, generally performs better in networks with random node mobility. The tightly coupled approach, however, has lower control overhead in both the cases.
The Antisymmetric Tensor Field in Superstring Theory

We discuss various aspects of the role of the antisymmetric tensor field in superstring theory, including the quantization law obeyed by its field strength and its role in topological defects and in vacuum configurations.
Collaboration and Competition in Special Libraries

ABSTRACTLibrarianship has a long tradition of collaboration and cooperation between libraries, but the literature yields scant evidence of formal partnerships in practice in special libraries. This column explores the barriers to collaboration for special libraries, from organizational culture to legal constraints, as well as the potential benefits and how librarians can overcome the barriers to reap these benefits. Different types of collaboration, including among similar special libraries and between special libraries and other types of libraries and related organizations, as well as informal and formal cooperation, and short-term and long-term partnerships, are discussed. Collaboration and cooperation were part of the impetus to form professional associations. The column provides a brief history of professional library associations and their role in supporting library partnerships in the United States. The conclusion explores how the increasingly digital nature of information and library work affects c...
Intravenous Warfarin and Heparin-Induced Thrombocytopenia Making the Diagnosis, Management, Modern Monitoring, and Multidisciplinary Care

Objective: To describe the diagnosis, management, and monitoring of a patient with heparin-induced thrombocytopenia (HIT) with thrombosis and simultaneous bleeding risk treated with argatroban and transitioned to intravenous (IV) warfarin secondary to the inability to administer enteral medications. Case Summary: A 71-year-old man was admitted to the surgical intensive care unit (SICU) following aortic valve repair, coronary artery bypass, and ascending aortic aneurysm repair. On postoperative day 9, he was found to have a pulmonary embolism, and therapeutic heparin was started. The following day, his platelet count was found to have dropped precipitously. HIT was diagnosed, heparin was discontinued, and argatroban was initiated. On postoperative day 22, anticoagulation was discontinued because of massive gastrointestinal bleeding. On postoperative day 35, multiple venous thromboses were found, and argatroban was restarted. The patient developed a high-output enterocutaneous fistula, eliminating the optio...
Cognitive outcome in children with rhombencephalosynapsis.

Abstract Purpose Rhombencephalosynapsis is a rare congenital cerebellar malformation increasingly recognized by prenatal and neonatal neuroimaging. Cognitive outcome seems to be variable but is not well documented. Aims and methods To study neurological, behavioural, and cognitive functions of patients with non-syndromic rhombencephalosynapsis, five patients (three female and two male, mean age at the time of this study 8.9 years, range 4.3–17.3 years) were assessed by neurological examination and several tests of behaviour and cognitive functions. Results Ataxia was present in all patients, but daily life activities were partly restricted in only one. Other symptoms were muscular hypotonia, abnormal eye movements, and head stereotypies. Three patients had pathological scores on both attention and hyperactivity/impulsivity scales. Only two patients had normal full-scale IQ (IQ value of 109 and 114, respectively). Verbal and/or performance IQ were impaired in three. Conclusion In non-syndromic rhombencephalosynapsis the clinical presentation is variable. Attention deficit and hyperactivity disorders are frequent behavioural problems. Cognitive functions are mostly impaired, as mild intellectual impairment without a typical cognitive profile. However, rhombencephalosynapsis is compatible with normal cognitive functions. No definitive correlation between cognitive impairment and additional supratentorial abnormalities could be established.
The spectral responses of Ceratophyllum demersum at varying depths in an experimental tank

This study was designed to investigate the spectral responses of Ceratophyllum demersum, a common submerged aquatic vegetation (SAV), with varying depth in columns of both clear and algae-laden water. The experiments were undertaken in a tank 20 500 l in volume, 360 cm in diameter and with a total depth of 150 cm. The first experiment was executed under a clear-water condition and the second was completed with an addition of algal solution to the tank. Spectral data were acquired using an ASD FieldSpec ultraviolet/visible and near-infrared (UV/VNIR) spectroradiometer with wavelengths ranging from 348-1074 nm. Results indicate that reflectance between 700-900 nm decreased as the depth of the macrophyte increased for both clear and algal-laden waters due simply to the absorption of light by the increasing volume of water. The 'green peak' of algal chlorophyll, on the other hand, increased as the depth to the macrophyte increased. The '700 peak' shifted towards shorter wavelengths as the macrophyte's depth i...
Estimation of the lattice entropy of rare‐earth compounds

Resolution of excess entropy of many types of transitions and estimation of standard entropy at 298.15K of compounds, for which experimental entropies have not yet been measured, depend on a reliable estimation of the lattice entropy. By taking into account the effects of cation mass and molar volume of the rare-earth compounds, the following formula is proposed for the estimation of the lattice entropy of isostructural iso-anionic rare-earth compounds. We have investigated 32 compounds, and found good agreements between estimated and experimental entropies.
Usefulness of Automated PCR Test for the Detection of Mycobacterium Tuberculosis in Fresh Biopsy Tissues

Bone and Serum Concentrations of Osteocalcin as a Function of 1,25-Dihydroxyvitamin D3 Circulating Levels in Bone Disorders in Rats

Osteocalcin, the vitamin K-dependent protein in bone containing gamma-carboxyglutamic acid, has been found to be significantly decreased in the osteomalacic bone of chicks made vitamin D deficient for 6 weeks. To evaluate whether this decrease in bone osteocalcin was due directly to the decrease or absence of vitamin D and its metabolites or to the secondary hypocalcemia and osteomalacia or other changes accompanying the deficiency of vitamin D, three experimental groups of Holtzman rats were studied. One group was made rachitic by a diet deficient in vitamin D, and the other groups were made rachitic by diets deficient in inorganic orthophosphate or calcium. The changes in bone and serum osteocalcin, serum 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3], and bone mineral content were evaluated, and morphological evaluation of bone was made. In the vitamin D-deficient animals, osteomalacia was evident histologically by 7 weeks, at which time serum 1,25-(OH)2D3 was not detectable, bone osteocalcin was decreased by 50%, and serum osteocalcin was decreased by 20%. In the animals fed a diet deficient in either calcium or inorganic orthophosphate but which were not depleted of vitamin D, the osteocalcin content of osteomalcic bone was normal, and an increase in the concentration of serum osteocalcin accompanied an increase in serum 1,25-(OH)2D3. These data are consistent with the conclusion that the metabolism of osteocalcin is affected by serum 1,25-(OH)2D3 and that the diminished level of osteocalcin in the bone of vitamin D-deficient animals is the result of a direct action of the metabolites and is not secondary to a decrease in the mineralization of bone tissue.
Traffic analysis for on-chip networks design of multimedia applications

The objective of this paper is to introduce self-similarity as a fundamental property exhibited by the bursty traffic between on-chip modules in typical MPEG-2 video applications. Statistical tests performed on relevant traces extracted from common video clips establish unequivocally the existence of self-similarity in video traffic. Using a generic communication architecture, we also discuss the implications of our findings on on-chip buffer space allocation and present quantitative evaluations for typical video streams. We believe that our findings open up new directions of research with deep implications on some fundamental issues in on-chip network design for multimedia applications.
Assessment of Right Atrial Pressure With 2-Dimensional and Doppler Echocardiography: A Simultaneous Catheterization and Echocardiographic Study

Objective To derive a clinically useful, noninvasive determination of right atrial pressure. Noninvasive assessment of right ventricular systolic pressure from Doppler-derived tricuspid regurgitant velocity requires an accurate assumption of right atrial pressure. Patients and Methods: Seventy-one patients were studied in the cardiac catheterization laboratory, comparing right atrial pressure (measured at mid systole) with simultaneous 2-dimensional echocardiographic measurement of inferior vena cava diameter and Doppler recordings of hepatic vein systolic, diastolic, and atrial reversal velocities. The initial 28 patients were used to derive a clinical algorithm to predict right atrial pressure, which was tested in the subsequent 43 patients. Results: Inferior vena cava dimension correlated directly with right atrial pressure (r2=0.74; P Conclusion: The combined information from inferior vena cava diameter and hepatic vein velocity curves can be used to assess right atrial pressure.
Evidence for nonanalytic light quark mass dependence in the baryon spectrum

Using precise lattice QCD computations of the baryon spectrum, we present the first direct evidence for the presence of contributions to the baryon masses which are nonanalytic in the light quark masses, contributions which are often denoted chiral logarithms. It is demonstrated that the $SU(3)$ flavor-singlet mass combination suffers the most severe convergence issues. The flavor-octet baryon mass splittings, which are corrected by chiral logarithms at next-to-leading order in $SU(3)$ chiral perturbation theory, yield baryon-pion axial coupling constants $D$, $F$, $C$ and $H$ consistent with QCD values, the first evidence of chiral logarithms in the baryon spectrum. The Gell-Mann--Okubo relation, a flavor-$\mathbf{27}$ baryon mass splitting, which is dominated by chiral corrections from light quark masses, provides further evidence for the presence of nonanalytic light quark mass dependence in the baryon spectrum; we simultaneously find the Gell-Mann--Okubo relation to be inconsistent with the first few terms in a Taylor expansion in ${m}_{s}\ensuremath{-}{m}_{l}$, which must be valid for small values of this $SU(3)$ breaking parameter. Additional, more definitive tests of $SU(3)$ chiral perturbation theory will become possible with future, more precise, lattice calculations.
Why Downside Beta Is Better: An Educational Example.

An educational example is presented that is an effective teaching illustration to help students understand the difference between traditional CAPM beta and downside (or down-market) beta and why downside beta is a superior measure for use in personal financial planning investment policy statements.
Partnering to Survive: Reflections on the Pursuit of Campus-Community Initiatives Prior to Tenure.

How does a early career faculty member survive the pursuit of campus-community initiatives? This article draws on experiences gained through a unique faculty position that combines community engagement with full academic responsibilities. "Survival" in this position emerges from the integration of community engagement with the institutional values of scholarship, as articulated by campus leaders and applied through academic disciplines in teaching and research, as well as the careful creation and institutionalization of reciprocal campus-community partnerships. The article provides lessons learned through adventures in applied teaching, negotiated criteria for tenure and promotion, and the cultivation of community relationships that have culminated in a truly "civic scholarship."
How to use: the neonatal neurological examination

The neurological exam can be a challenging part of a newborn's full evaluation. At the same time, the neonatal neurological exam is a useful tool in identifying babies needing closer evaluation for potential problems. The Dubowitz assessment is a standardised approach to the neonatal neurological exam designed for use by paediatricians in routine practice. Evidence has validated this technique and delineated its utility as a screening exam in various populations. This paper reviews clinical application of the Dubowitz assessment of the newborn.
Inventory Record Inaccuracy in Retail Supply Chains

Inventory record inaccuracy (IRI), defined as the discrepancy between the recorded inventory quantity and the actual inventory quantity physically available on the shelf, is a substantial problem in retailing. This article summarizes the research documenting the problem of IRI within retail supply chains and reviews several potential solutions to IRI offered by operations management researchers. In addition, this article explores how execution problems within retail distribution centers contribute to store-level IRI. Through direct observations and interviews with retail employees, we identify numerous errors that occur within the retail distribution center and how such errors create a mismatch between actual and recorded store inventory. We argue that it is critical to detect, determine the root cause of, and correct such errors in an effort to prevent them from cascading from one stage of the distribution process to the next. We claim error prevention in distribution, similar to quality improvement in manufacturing, requires improving workforce practices, fool proofing operational processes, and appropriate incentive design. We conclude with our recommendations for further study on this topic. Keywords: inventory record inaccuracy; discrepancies; distribution center; audit frequency; product variety; inventory density; retail execution; vendor-managed inventory; process improvement; inventory replenishment
A putative new ampelovirus associated with grapevine leafroll disease

A putative new ampelovirus was detected in Vitis vinifera cv. Carnelian showing mild leafroll symptoms and molecularly characterized. The complete genome consisted of 13,625 nt and had a structure similar to that of members of subgroup I in the genus Ampelovirus (fam. Closteroviridae). In-depth analyses showed that the virus from cv. Carnelian is the most distinct member of the “GLRaV-4 lineage” of ampeloviruses, which comprises GLRaV-4, -5, -6, -9, and the recently characterized GLRaV-Pr, and GLRaV-De. This virus appears to be a new member of the family Closteroviridae, for which the provisional name grapevine leafroll-associated Carnelian virus is proposed.
Queer Things from Old Closets: Libraries—Gay and Lesbian Studies—Queer Theory

There is not one but many silences, and they are an integral part of the strategies that underlie and permeate discourses.— Michel Foucault1 In November 1991 nearly 2,000 faculty members, graduate and undergraduate students, activists, gays, lesbians, queers, queens, butches, femmes, People With AIDS, and heterosexuals converged at Rutgers University to present papers, take part in panels, and discuss important issues with colleagues at the Fifth Annual Gay and Lesbian Studies Conference. The overwhelming diversity of gay and lesbian studies that has manifested itself in academia during the past five years was illustrated by the 100 different events and more . . .
Decreased N-TAF1 expression in X-linked dystonia-parkinsonism patient-specific neural stem cells

X-linked dystonia-parkinsonism (XDP) is a hereditary neurodegenerative disorder involving a progressive loss of striatal medium spiny neurons. The mechanisms underlying neurodegeneration are not known, in part because there have been few cellular models available for studying the disease. The XDP haplotype consists of multiple sequence variations in a region of the X chromosome containingTAF1, a large gene with at least 38 exons, and a multiple transcript system (MTS) composed of five unconventional exons. A previous study identified an XDP-specific insertion of a SINE-VNTR-Alu (SVA)-type retrotransposon in intron 32 ofTAF1, as well as a neural-specific TAF1 isoform, N-TAF1, which showed decreased expression in post-mortem XDP brain compared with control tissue. Here, we generated XDP patient and control fibroblasts and induced pluripotent stem cells (iPSCs) in order to further probe cellular defects associated with this disease. As initial validation of the model, we compared expression ofTAF1and MTS transcripts in XDP versus control fibroblasts and iPSC-derived neural stem cells (NSCs). Compared with control cells, XDP fibroblasts exhibited decreased expression ofTAF1transcript fragments derived from exons 32-36, a region spanning the SVA insertion site. N-TAF1, which incorporates an alternative exon (exon 34'), was not expressed in fibroblasts, but was detectable in iPSC-differentiated NSCs at levels that were ∼threefold lower in XDP cells than in controls. These results support the previous findings that N-TAF1 expression is impaired in XDP, but additionally indicate that this aberrant transcription might occur in neural cells at relatively early stages of development that precede neurodegeneration.
Challenging Casanova: Beyond the Stereotype of the Promiscuous Young Male

Most people believe young men are primarily interested in short-term "hookup" sex and uninterested in relationships. In this talk, Dr. Andrew Smiler explores how we have come to believe this image of young men. He will discuss some of his research on young men's dating and sexual experiences, much of which challenges the stereotypical portrayal of young men as "Casanovas."
Assessing pain in older adults.

WHY: Studies on pain in older adults (persons 65 years of age and older) have demonstrated that 25%45% of community dwelling older people have chronic pain. 45-85% of nursing home residents also report pain that is often left untreated. Although there is minimal research that strictly focuses on pain in older adults, studies with younger participants have elucidated associations between pain and depression. Increased pain has further resulted in decreased socialization, impaired ambulation and increased healthcare utilization and costs. Older adults are reluctant to report pain: therefore, nurses need to be proactive in screening for and assessing pain.
Socially and Ecologically Responsible Historical Geography

As a discipline, historical geography emerged out of basic research conducted for scholarly purposes. Its traditional role has been to serve academic needs. More recently, historical -geographical expertise is serving public service interests. "Applied" historical geography involves historic preservation, forensics, historical-recreational resource management, and cultural resource inventory. The extension of scholarly historical geography into the domain of present day policyand decision-making, planning, and management bears the potential to significantly reshape and refocus the discipline. This essay briefly reviews recent trends in applied historical-geographical research, points out associated benefits and risks, and suggests policies that might reasonably be adopted to insure that historical geography's public service role will be developed to the mutual benefit of historical geographers and society.
X-Ray Topographic Analysis of Strain Fields Associated with Micron-Sized Gratings on Si(100) Surfaces

Si(100) single crystals containing circular gratings etched into the surface using reactive ion etching were analysed using both monochromatic and white beam reflection X-ray topography. Some features of observed X-ray topographic contrast associated with the gratings were modelled using a diffracting zone model, based on a simple radial in-plane strain field. Reasonable agreement was obtained between this model and observations.

Investigation On The Outcomes And Influencing Factors Of 355 HBsAg Carriers

Objective To study the outcomes and influencing affecting factors of 355 HBsAg carriers,and provide evidence for control strategy.Methods 355 HBsAg carriers found by the 1993 census were identified as the research objects,and a questionnaire survey,retrospective review of medical records and serological detection were conducted respectively among these objects in 1999 and 2008 to learn the outcomes of HBsAg carriers,such as the occurrence of negative conversion or development of hepatitis B(HBV),liver cirrhosis,liver cancer,etc.,and analyze the factors affecting the outcomes.Results During the retrospective investigation,33 cases of 355 HBsAg positive objects became negative,12 cases became HBV,1 case became liver cirrhosis,6 cases became liver cancer,and 14 cases died.Among 14 death cases,5 cases died of liver disease.Logistic regression analysis whether liver disease will occur showed that farmers or people whose parents had liver disease were risk factors,physical exercise,interference treatment was protective factors,and gender,age and other factors had no statistical significance.Conclusion The probability was very little that HBsAg carriers change to HBsAg negative.Some HBsAg carriers will develop chronic Hepatitis B,liver cirrhosis or liver cancer.So some physical exercise should be done,and appropriate interference treatment should be taken by HBsAg carriers.
Introducing Glucose Oxidase Gene into O. sativa ssp. Indica from Transgenic Oryza sativa L. ssp. japonica Utilizing Sexual Hybridization

The glucose oxidase gene was introduced into O.sativa ssp.Indica shuhui162 from transgenic Oryza sativa L.ssp.japonica.Nipponbare by the way of sexual hybrid for the first time,the integration and transcribe of glucose oxidase gene was confirmed by RT-PCR analysis on shuhui 162 rice genome,it proved the GO gene can be transfered between Indica and japonica.The color reaction with starch-KI showed that the glucose oxidase gene had expressed in the level of protein and exerted its function in shuhui 162 rice.The paper discussed the further utilization of GO gene shuhui 162 and the security of GO gene.

Irony made manifest: cultural contention and Córdoba’s Mosque-Cathedral

ABSTRACTCordoba’s Mezquita (“mosque”) has been the focus of much recent attention, following decisions that are both significant for the building’s future and indicative of larger issues in Spain. In March of 2016 a report concluded that the mosque-cathedral does not “belong” to anyone; that same month the Catholic Church, which administers the site, announced it will revert to “Mosque-Cathedral” in official literature after attempts to refer to the site as the “Cordoba Cathedral.” Efforts to change the name align with policy that forbids Muslim worship in the monument; the Church denied formal proposals requesting permission for such worship in 2004 and 2006, and tensions escalated in 2010 when Muslim visitors were arrested upon attempting to pray. A World Heritage Site for the express use of all peoples, the Mezquita and the contentions surrounding it are thus fraught with ironic meaning. This article examines the ironies of the space and the related debates that are both symbolic and symptomatic of mor...
Secure Alamouti MAC Transmissions

We investigate the physical layer security of synchronous multiple access transmissions using the Alamouti space-time block code in fading channels where multiple users communicate with a single intended receiver in the presence of an eavesdropper. We propose an artificial-noise-aided technique to secure the transmissions by having the Alamouti users collaborate with each other, without exchanging information, to degrade the eavesdropper’s channel. Unlike previous work, which assumes that the transmitters have complete knowledge of the legitimate as well as the eavesdropper’s channels, our proposed technique requires no communications between the users, minimal knowledge of the legitimate channel, and no channel knowledge regarding the eavesdropper.
Opioid pain medication prescriptions obtained through emergency medical visits in the Veterans Health Administration

Objective: This study sought to characterize national patterns for opioid pain medication (OPM) prescriptions received during emergency medical encounters in the Veterans Health Administration (VA). Design: The authors conducted a retrospective study of all emergency department (ED) visits by adults in the VA between January 2009 and June 2015. We examined demographics, comorbidities, utilization measures, diagnoses, and prescriptions. Main Outcome Measures: The percentage of ED visits that culminated in the receipt of a prescription for an OPM. Results: There were 6,721,134 emergency medical visits by 1,708,545 individuals during the study period. An OPM was prescribed during 913,872 visits (13.6 percent), and 407,408 individuals (27.5 percent) received at least one OPM prescription. Prescriptions for OPMs peaked in 2011 at 14.5 percent, declining to 12.3 percent in 2015. The percentage of prescriptions limited to 12 pills increased from 25.0 to 32.4 percent. The heaviest users (top 1.5 percent, n = 7,247) received an average 602.5 total doses, and had at least 10 ED visits during the study period. The most frequently prescribed OPMs were acetaminophen/hydrocodone, followed by tramadol and acetaminophen/oxycodone. Receiving a prescription was associated with younger patients, musculoskeletal diagnoses, higher pain scores, a history of chronic pain, a history of mental illness, a history of substance abuse, prior heavy prescription OPM use, and lower participation in outpatient services. Conclusions: The writing of OPM prescriptions after an ED visit is on the decline in the VA. Compliance with prescribing guidelines is increasing, but is not yet at goal.
Soybean Row Spacing and Seeding Rate

Recommendations for soybean seeding rates have been targeted between 125,000 and 140,000 seeds/acre with the objective of targeting a final plant population of at least 100,000 plants/acre. It is understood a 15-in. row spacing has approximately 4.5 bushels/acre higher yields than 30-in. row spacing. Even though this advantage has been identified, the shift to 15-in. rows has not occurred. In recent years, 20-in. row spacing planters have become available. Therefore, this trial was designed to begin to look at seeding rate advantages in 20-in. rows compared with 15-in. and 30-in. row spacing.
On the unimodality of the price-setting newsvendor problem with additive demand under risk considerations

Abstract We present a mean–variance analysis of the single-product, single-period, price-setting newsvendor problem with additive, price-dependent demand. The main goal of this paper is to use a mean–variance framework to solve any risk-sensitive instance and find conditions under which the unimodality of the problem is guaranteed. We introduce such conditions via the lost sales rate elasticity, the elasticity of the optimal price, and the elasticity of the expected safety stock surplus to provide managerial insight in terms of the newsvendor’s level of service. We also simplify the optimization problem in case that those conditions do not hold. The main contribution of this paper is that, by evaluating the unimodality of the problem for any possible risk attitude, it extends previously published results found for the concavity of the solution in risk-neutral and moderately risk-sensitive cases.
Faculty Behaviors Influencing Intent to Pursue Graduate Education Among RN-BSN Students

Abstract Record numbers of nurses are returning to school for their bachelor of science degree in nursing (BSN). The purpose of this study was to determine if supportive and caring behaviors of nursing faculty influence registered nurse-to-BSN students' decision to pursue graduate education in nursing. This descriptive correlational study found statistically significant positive relationships ( p
Sea Level Rise Impacts to Coastal Marshes may be Ameliorated by Natural Sedimentation Events

Coastal wetland sustainability in the future will likely depend on the extent to which increases in sea level drive flooding duration, plant submergence, and higher salinities, and how wetlands respond to these changes. Coastal wetlands will need to grow vertically to cope with rising seas, and sedimentation, often observed following hurricane passage, could play a role. A greenhouse mesocosm experiment was conducted to investigate if the impacts of sea level rise (SLR) and elevated salinity on the productivity and resilience of Spartina alterniflora marshes could be mediated by simulated hurricane sedimentation. Overall, sedimentation ameliorated the negative impacts of moderate SLR on plant productivity and resilience. Sedimentation improved growth conditions at current and moderate increases in sea level by reducing flooding duration, which in-turn, increased soil Eh, and lowered porewater sulfide. This led to greater productivity of vegetation above- and belowground and improved plant resilience. However, at the highest sea levels, inundation stress was too great for the benefits of added sediment to be realized. Thus, it is likely that the sustainability of coastal marshes will be improved by hurricane-generated sedimentation under moderate SLR scenarios, but will see no improvement with more extreme SLR.
Integrating background knowledge into text classification

We present a description of three different algorithms that use background knowledge to improve text classifiers. One uses the background knowledge as an index into the set of training examples. The second method uses background knowledge to reexpress the training examples. The last method treats pieces of background knowledge as unlabeled examples, and actually classifies them. The choice of background knowledge affects each method's performance and we discuss which type of background knowledge is most useful for each specific method.
Intraoperative Electron Radiation Therapy

The earliest known use of the IORT was in Barcelona, Spain, in 1905 for a patient with an advanced carcinoma of the uterine cervix. The patient was treated by hysterectomy, partial cystectomy, and node dissection on February 18 and the wound left open until March 11. Five fractions were administered over a several week period. The patient also received external beam therapy. She was reported to have been a disease-free survivor at 10 years [2]. A small number of patients were treated by IORT in European centers prior to WWII. Six patients were treated at Stanford and reported in 1937. Frank Ellis employed 250 kVp x-rays for IORT at the London Hospital in ∼1941. After the war, Ellis moved to Oxford and in ∼1960 received funding for a linear accelerator. The unit was installed in an OR at the Churchill Hospital. To his serious regret the machine was never functional. In Japan, Abe of University of Kyoto began a study of IOERT in the 1960s, particularly for gastric and bladder carcinoma patients. Then, U. Henschke at Howard University commenced a major IOERT program in 1976.
The Democracy Deficit: Taming Globalization Through Law Reform

Economic globalization has had a chilling effect on democracy since markets now do some of the work that governments used to do through the political process. More than two decades of deregulation have made a healthy economy appear to depend on unrestrained markets. But appearances are misleading-globalization is also a legal and political process. The future of democracy in the twenty-first century depends on the ability of citizens to reclaim a voice in taming globalization through domestic politics and law reform. "The book's topic could not be more important: how do we adapt contemporary democratic governance- and contemporary administrative law- to the challenge of a globalizing world?"-Kal Raustiala, UCLA School of Law Can citizens govern globalization? Aman argues that they can, and that domestic law has a crucial role to play in this process. He proposes to redefine the legal distinction between public and private to correspond to the realities of the new role of the private sector in delivering public services, and thereby to bring crucial sectors of globalization back within the scope of democratic reform. Basing his argument on the history of the policies that led to globalization, and the current policies that sustain it, Aman advocates specific reforms meant to increase private citizens' influence on globalization. He looks at particular problem areas usually thought to be domestic in nature, such as privatization, prisons, prescription drugs, and the minimum wage, as well as constitutional structural issues such as federalism and separation of powers.
On the Similarities and Differences Among Contact Models in Robot Simulation

Over the past several decades, as affordable computational power has increased, simulation has become increasingly important in robot analysis, planning, and control. Smooth robot dynamics can be simulated efficiently and accurately, and therefore, readily used in model-based control schemes. However, some of the most difficult and important problems in robotics, such as running, grasping, and parts assembly, involve intermittent frictional contacts, which introduce extreme nonlinearities into the dynamics. Numerous approaches have been developed to simulate contact dynamics. Even though real bodies are not rigid, idealized rigid contact models have been used widely and productively for decades. However, the resulting nonsmooth dynamics can be computationally difficult to solve or use in model-based planning and control, motivating researchers to propose various relaxations of the idealized contact models. The varied origins and formulations of these approaches can obscure their similarities and differences. In this letter, we identify and explain differences between four contact models. We present the models in the context of one solver that is applicable to all of them, namely Projected Gauss-Seidel, in order to highlight their common structure and to avoid confounding their comparison with differences in the solution methods. Simulation results from sliding, wedging, grasping, and stacking experiments illustrate consequences of the differences. The results can help inform roboticists when comparing and selecting models for their specific applications.

Effectiveness of Deep Learning Algorithms to Determine Laterality in Radiographs

Develop a highly accurate deep learning model to reliably classify radiographs by laterality. Digital Imaging and Communications in Medicine (DICOM) data for nine body parts was extracted retrospectively. Laterality was determined directly if encoded properly or inferred using other elements. Curation confirmed categorization and identified inaccurate labels due to human error. Augmentation enriched training data to semi-equilibrate classes. Classification and object detection models were developed on a dedicated workstation and tested on novel images. Receiver operating characteristic (ROC) curves, sensitivity, specificity, and accuracy were calculated. Study-level accuracy was determined and both were compared to human performance. An ensemble model was tested for the rigorous use-case of automatically classifying exams retrospectively. The final classification model identified novel images with an ROC area under the curve (AUC) of 0.999, improving on previous work and comparable to human performance. A similar ROC curve was observed for per-study analysis with AUC of 0.999. The object detection model classified images with accuracy of 99% or greater at both image and study level. Confidence scores allow adjustment of sensitivity and specificity as needed; the ensemble model designed for the highly specific use-case of automatically classifying exams was comparable and arguably better than human performance demonstrating 99% accuracy with 1% of exams unchanged and no incorrect classification. Deep learning models can classify radiographs by laterality with high accuracy and may be applied in a variety of settings that could improve patient safety and radiologist satisfaction. Rigorous use-cases requiring high specificity are achievable.
Sexual Abuse of Children

Childhood sexual abuse has been defined as any sexual experience between a child (usually defined as under age 16) and an adult or person at least 5 years older than the child (Finkelhor, 1979). The definition includes a wide range of acts, including exhibitionism, fondling, intercourse, and pornography. “Recent epidemiological findings from adults” retrospective reports indicate that as many as 19% to 28% of women and 8.6% to 16% of men report at least one sexual victimization experience during childhood (Finkelhor, 1979; Russell, 1983; Timnick, 1985). The majority of sexually abusive experiences involve “serious” to “very serious” forms of abuse that have the potential for psychological trauma and short- and long-term sequelae. Finkelhor’s (1979) survey of college students revealed that 20% of his sexually abused sample had experienced exhibitionism, 40% reported genital fondling, and 40% reported either oral-genital contact or vaginal or anal intercourse. Similar statistics were reported by Russell (1983) for a sample of women who were sexually abused as children. Twenty-three percent reported “very serious” sexual contact (penile penetration of the vagina or anus, fellatio, cunnilingus, analingus) and41% reported “serious” sexual contact (digital vaginal penetration, unclothed fondling of breasts or genitals, and simulated or attempted intercourse).
Unobtrusive Occupancy Detection with FastGRNN on Resource-Constrained BLE Devices

The emerging area of device-free occupancy detection (DfOD) has seen slow adoption due to deployability, scalability, and energy efficiency concerns resulting from the use of large, costly, and power-hungry devices like laptops and WiFi routers in the state-of-the-art solutions. Moreover, these approaches often rely on cloud-offloading for data processing which requires extra communication latency and energy. To overcome these challenges, we develop an RF-based DfOD system using easily-deployable Bluetooth Low Energy (BLE) devices. Our system uses a kilobyte-sized machine learning algorithm running on the BLE device to predict the occupancy of a room from a small number of wireless packets, thereby enabling energy-frugal realtime analytics. We validate our approach with experiments in two indoor rooms using four nRF52840 BLE radios. Initial results suggest our system can detect occupancy of an indoor environment with 95% accuracy, 96% precision, and 92% recall while drawing a meager amount of current.
FasTest: A Concurrent Strategy to Test Components of 3D Network-on-Chips

In this paper, we propose an in-field test strategy to make sure that the most important hardware components of a 3D NoC i.e., FIFO buffers and crossbar switches, are up and functioning as expected. Unlike previous schemes, our proposed test strategy runs as a background process and does not interfere with the normal operation of the chip i.e., it uses two always-ON test architectures to minimize the failure detection latency. The testing architectures keep giving feedback to the routing unit of NoC to avoid using failed components for future packets. Our network level evaluations show that the proposed test strategy reduces the number of packets that were previously dropped due to in-field failures of NoC components by 93%. This is achieved with a negligible network delay increase when there are failed components, and zero-increase in the network delay when there is no failed component in the chip. The synthesis results of our Verilog implementation show that the hardware and power consumption overheads of the proposed test architecture are limited to 3.2% and 2.1% respectively.
“Lead the district into the light”: Solar energy infrastructure injustices in Kerala, India

Abstract Solar energy represents a fossil fuel alternative to meet India’s rising energy demand. Large mega-watt solar projects require contiguous land, which is sparse in the South Indian state of Kerala. Drawing from ethnographic research in Kerala, this paper traces the role that solar infrastructure plays in making and unmaking land and lives in pursuit of light. Government officials promoted the Kasaragod solar park and associated green corridor transmission line as climate-friendly infrastructure development for the energy deficit state. Select government officials encouraged solar projects as the renewable resource would help, “lead the district into the light.” Although the energy infrastructure promoters promised development benefits for local stakeholders, Adivasis (indigenous peoples) without legal land titles and others opposed the acquisition of their land for the solar project. The Kasaragod Solar Park exemplifies how national climate goals for renewable energy and empty infrastructure pledges translated into the reification of land unevenness, with particularly profound implications for Adivasis. This reproduction of socio-environmental injustices did not go unchallenged. Local political opposition significantly reduced the 200 Megawatt (MW) solar park to 50 MW, but not before some Adivasis and others without land titles lost their land and livelihoods. This case illustrates how the completion of renewable energy infrastructure to meet national and state climate goals may hinge on the assertion of local political power to thwart or promote large-scale projects. Efforts to pursue ambitious national renewable energy infrastructure goals without recognition of historical land and development unevenness may hinder India’s capacity to pursue renewable energy transition goals.
Cosmetic Tattooing and Early Onset Basal Cell Carcinoma: A Population-based Case-Control Study from New Hampshire

Background Cosmetic tattoos use dyes with carcinogenic potential. Skin cancers arising in tattoos have been reported. Methods We investigated whether risk of early onset basal cell carcinoma was related to the site and colors of cosmetic tattoos as part of a population-based case-control study of cases (ages 25-50 years), identified from a state-wide surveillance system, and age- and gender-matched controls, selected from driver's license records, randomly assigned an anatomic site of the cases. Results One hundred fifty-six cases (17%) with early onset basal cell carcinoma and 213 controls (26%) reported cosmetic tattoos. Among those with tattoos, the adjusted odds ratio of basal cell carcinoma at the tattoo site compared to another site was 1.8 (95% confidence interval = 1.0, 3.2). We observed the strongest associations for yellow and green tattoo colors. Conclusion Our preliminary findings support the possibility of an enhanced risk of early onset basal cell carcinomas at the site of cosmetic tattoos.
