Consistency conditions for gauge theory S matrices from requirements of generalized unitarity.

In the modern on-shell approach, the perturbative $S$ matrix is constructed iteratively using on-shell building blocks with manifest unitarity. As only gauge invariant quantities enter in the intermediate steps, the notion of a gauge anomaly is absent. In this Letter, we rephrase the anomaly cancellation conditions in a purely on-shell language. We demonstrate that while the unitarity methods automatically lead to a unitary $S$ matrix, the rational terms that are required to enforce locality, invariably give rise to inconsistent factorization channels in chiral theories. In four dimensions, the absence of such inconsistencies implies the vanishing of the symmetric trace of three generators. In six dimensions, if the symmetric trace of four generators does not vanish, the rational term develops a factorization channel revealing a new particle in the spectrum: the 2-form of the Green-Schwarz mechanism. Thus, in the purely on-shell construction, the notion of a gauge anomaly is replaced by the difficulty to consistently impose locality on the unitary $S$ matrix.
GENOTYPIC VARIETIES OF LA CROSSE VIRUS ISOLATED FROM DIFFERENT GEOGRAPHIC REGIONS OF THE CONTINENTAL UNITED STATES AND EVIDENCE FOR A NATURALLY OCCURRING INTERTYPIC RECOMBINANT LA CROSSE VIRUS

The tripartite ribonucleic acid (RNA) genomes of 23 alternate isolates of La Crosse virus have been analyzed by the procedure of oligonucleotide fingerprinting. By comparison with the fingerprints of the three viral RNA species (large, medium and small) of prototype La Crosse virus, the viruses have been categorized in terms of the degree of their RNA sequence relatedness. The A type La Crosse viruses, which have been recovered from Wisconsin, Minnesota, Indiana and Ohio, have viral RNA sequences that are closely related to those of prototype La Crosse virus. The B type La Crosse viruses, which have been recovered from Minnesota, Wisconsin and Illinois, have RNA sequences which, although related, are easily distinguished from those of type A viruses. A La Crosse virus isolate obtained from Rochester, Minnesota, appears to be an intertypic type A/B recombinant, it has a small size RNA segment like those of the B type La Crosse virus isolates, but medium- and large-sized RNA species like those of the A type La Crosse virus isolates. The C type La Crosse viruses have viral RNA sequences that neither closely resemble the A or B type La Crosse viruses. They have been recovered from eastern Ohio, New York State, Texas, Georgia and North Carolina.

Gene editing technology as an approach to the treatment of liver diseases.

ABSTRACTIntroduction: More than 100 liver-related disorders are caused by mutations in a single gene. These include both inherited and acquired genetic disorders. The development of nucleic acid-based therapies for liver diseases has been severely restricted due to many undesirable side effects and methodological limitations.Areas covered: In recent years, however, efforts have been intensified to address these issues, and to develop liver-targeted approaches using novel gene editing technologies, including ZFN, TALEN, CRISPR/Cas and PITCh. While each of these methods utilizes a distinct mechanism of gene modification at the genomic level, they all are dependent on an efficient delivery system to the target site within the host cell. This review will provide an overview on current and emerging therapeutic strategies for the treatment of liver diseases.Expert opinion: Clinical trials for liver gene therapy have entered an exciting stage and are already showing promise with the development of novel technolo...
The Metamorphosis of Slavery, 1865–1900

The shock of emancipation, coming as it did during an unsuccessful war, hardened the hearts of southern whites; defeated, they were unvanquished. From nearly every street corner and manor house, wrote observers, southern whites threatened to reenslave blacks as soon as northern occupation ended. Meanwhile, landlord and tenant entered into contracts sharing land and labor, and blacks discovered that emancipation did not signal equal rights-or even in some cases freedom. Like a patchwork quilt, the new labor system in the South was varied and complex, an unpatterned blend of illiteracy, law, contracts, and violence, confusing, if not incomprehensible, even to those closest to it. The complexity of economic adjustment was eclipsed by the violence and corruption associated with politics, and the era of Reconstruction became, for those who lived through it and for historians who wrote of it, too emotionally charged to explain rationally. Perhaps agreeing with Albion Tourgee that Reconstruction was "a fool's errand," northerners gradually lost interest in policing the South and allowed white southerners, within bounds, to handle the race problem. Spokesmen as varied, at least in color, as Booker T. Washington and Henry Grady gave their benedictions to the New South; in an age that glorified progress, they accepted it warts and all.1

AL preincubation inhibits calcification of bioprosthetic heart valve tissue in the rat subdermal model.

To date, the clinical usefulness of bioprosthetic heart valves (BPV) fabricated from glutaraldehyde pretreated porcine aortic valves or bovine pericardium has been limited because leaflet calcification (CALC) leads to valvular stenosis and/or regurgitation and subsequent valve failure. The present study was designed to test the hypothesis that preincubation of glutaraldehyde pretreated pericardial BPV leaflets in a solution containing the trivalent cation, AL , inhibits BPV calcification. BPV tissue was preincubated in 0.1 M ALCL3 for 24 hours (T = 25 degrees C), then subdermally implanted in rats (weanling, male, CD, Sprague-Dawley) for 21 days. Compared to the control group (tissue Ca++ = 143.81 +/- 25.49 micrograms/mg), calcification was markedly inhibited in the group pretreated with AL (tissue Ca++ = 4.1 +/- 1.03 micrograms/mg) after a 21 day implant. No adverse effects on rat growth or bone morphology were detected. It is concluded that the trivalent cation AL provided a marked anticalcification effect for BPV tissue implanted subdermally in the rat for 21 days.
Ontology Search and Text Mining of MEDLINE Database

With the explosion of biomedical data, information overload and users’ inability of expressing their information needs may become more serious. To solve those problems, this chapter presents a text data mining method that uses both text categorization and text clustering for building concept hierarchies for MEDLINE citations. The approach we propose is a three-step data mining process for organizing MEDLINE database: (1) categorizations according to MeSH terms, MeSH major topics, and the co-occurrence of MeSH descriptors; (2) clustering using the results of MeSH term categorization; and (3) visualization of categories and hierarchical clusters. The hierarchies automatically generated may be used to construct multiple viewpoints of a collection. Providing multiple viewpoints of a document collection and allowing users to move among these viewpoints will enable both inexperienced and experienced searchers to more fully exploit the information contained in a document collection. User interfaces with multiple viewpoints for this underlying system are also presented.
Reprocessing of HIRS Satellite Measurements from 1980 to 2015: Development toward a Consistent Decadal Cloud Record

AbstractThis paper presents the cloud-parameter data records derived from High Resolution Infrared Radiation Sounder (HIRS) measurements from 1980 through 2015 on the NOAA and MetOp polar-orbiting platforms. Over this time period, the HIRS sensor has been flown on 16 satellites from TIROS-N through NOAA-19 and MetOp-A and MetOp-B, forming a 35-yr cloud data record. Intercalibration of the Infrared Advanced Sounding Interferometer (IASI) and HIRS on MetOp-A has created confidence in the onboard calibration of this HIRS as a reference for others. A recent effort to improve the understanding of IR-channel response functions of earlier HIRS sensor radiance measurements using simultaneous nadir overpasses has produced a more consistent sensor-to-sensor calibration record. Incorporation of a cloud mask from the higher-spatial-resolution Advanced Very High Resolution Radiometer (AVHRR) improves the subpixel cloud detection within the HIRS measurements. Cloud-top pressure and effective emissivity (ef, or cloud em...
Problems in the determination of anisotropic transport properties in very thin polymer fibers

The technological need often arises to know the conductivity of a thin fiber. There are numerous references in the literature to the conductivity of fibers but when one looks in detail at these references it is found that the measurements have been made on woven fabrics or mats of fibers.
Energy Storage Methods - Superconducting Magnetic Energy Storage - A Review

Energy storage is very important for electricity as it improves the way electricity is generated,delivered and consumed. Storage of energy helps during emergencies such as power outages fromnatural calamities, equipment failures, accidents etc. It is very challenging to balance the powersupply needs with the demand instantaneously within milliseconds. This makes power networksmore resilient and ecient. Storage of excess energy, to meet the ever increasing levels of primaryenergy derived from renewable sources needs further development and advancement. The intro-duction of environmentally-conscious policies to lower greenhouse gas emissions and increase thesecurity of energy supplies heavily in uences the market rules today. All these factors have led toexplore renewable energy sources, their use to meet the ever increasing energy demand and electricalenergy storage (EES). One of the energy storage methods, superconducting magnetic energy storage(SMES),will be discussed in this paper.
Overview of the Evolving Recognition of the Health Effects of Excessive Alcohol Use Over the Past Two Centuries Including the Classic Citations

The negative behavioral and social consequences of alcohol ingestion, particularly when done so in excess, have been recognized for thousands of years and have led to various types of prohibition imposed on religious, moral, or social grounds in nearly every society at one time or another. However, the relatively modern era of medicine has only more recently documented and investigated the adverse health effects of excessive alcohol consumption. Although the pathophysiological effects of alcohol on the liver and the brain are more widely recognized and have attracted much of the attention by physicians and scientists, alcohol abuse has a myriad of systemic targets including the lung. In fact, it has been recognized for more than two centuries that alcohol abuse is a major risk factor for pneumonia. More recently, clinical observations have identified that alcoholics are at risk for much poorer outcomes if they develop certain pneumonias such as from Streptococcus pneumoniae. Further, even more recent epidemiological studies have identified that alcohol abuse significantly increases the risk of acute lung injury following acute insults such as sepsis or trauma. This chapter highlights some of the classic observations and discoveries of the relationship between alcohol use and lung disease over the past two centuries and sets the stage for the more detailed analyses and accounts of the current state of our knowledge of specific facets of this relationship in subsequent chapters.
Magnetization-prepared shells trajectory with automated gradient waveform design.

PURPOSE To develop a fully automated trajectory and gradient waveform design for the non-Cartesian shells acquisition, and to develop a magnetization-prepared (MP) shells acquisition to achieve an efficient three-dimensional acquisition with improved gray-to-white brain matter contrast. METHODS After reviewing the shells k-space trajectory, a novel, fully automated trajectory design is developed that allows for gradient waveforms to be automatically generated for specified acquisition parameters. Designs for two types of shells are introduced, including fully sampled and undersampled/accelerated shells. Using those designs, an MP-Shells acquisition is developed by adjusting the acquisition order of shells interleaves to synchronize the center of k-space sampling with the peak of desired gray-to-white matter contrast. The feasibility of the proposed design and MP-Shells is demonstrated using simulation, phantom, and volunteer subject experiments, and the performance of MP-Shells is compared with a clinical Cartesian magnetization-prepared rapid gradient echo acquisition. RESULTS Initial experiments show that MP-Shells produces excellent image quality with higher data acquisition efficiency and improved gray-to-white matter contrast-to-noise ratio (by 36%) compared with the conventional Cartesian magnetization-prepared rapid gradient echo acquisition. CONCLUSION We demonstrated the feasibility of a three-dimensional MP-Shells acquisition and an automated trajectory design to achieve an efficient acquisition with improved gray-to-white matter contrast.

The 1925 Geneva Protocol: China’s CBW Charges Against Japan at the Tokyo War Crimes Tribunal

The 1925 Geneva Protocol, which bans the wartime use of chemical and also biological weapons, was an emphatic reaction to the use of chemical weapons in World War I, but legal institutions that would sanction violations of the treaty have evolved only with difficulty. An important example of a legal failure to support the protocol occurred at the 1946–1948 International Military Tribunal for the Far East (IMTFE), just when it might be expected that Imperial Japan would be charged for its chemical and biological warfare (CBW) waged against China from the late 1930s into World War II. In 1937, the Chinese officially presented its first complaints to the League of Nations about Japan’s battlefield use of chemical weapons (mustard gas, phosgene and tear gases) against defenseless Chinese troops and civilians. In addition, in early 1941 and after, China accused Japan of launching plague attacks against key Chinese cities, killing hundreds and terrorizing thousands. None of these accusations, although supported by evidence, brought about serious international recriminations for Japan. Once World War II ended, China expected to revive these charges at the IMTFE in Tokyo. Instead, under the influence of a few key figures in US military intelligence, the trial’s International Prosecution Section (IPS) deleted the Chinese charges and for decades Japan’s infraction were lost to history. Analysis of this legal failure points to the obstacles posed by growing Cold War antagonisms between the United States and the Soviet Union, which prompted a general American retreat from prosecuting Japan, its new democratic ally in East Asia, as well as the internal processes at the IPS that favored more blatant incidents of Japanese wartime aggression—such as the well-documented 1937 “Rape of Nanjing” and abuses of Allied prisoners of war. After the silence imposed at the IMTFE, chemical and biological weapons proliferated with few restraints until the Cold War ended in 1992. At the same time, the international framework for war crimes prosecution greatly changed with greater attention put on crimes against civilians. Yet, lacking precedent, international readiness to legally sanction violations of the Geneva Protocol—as with the 2013 and 2017 murders of Syrian civilians with nerve gas—remains nearly as ambiguous as it was in 1946.
Tax Benefit Complexity and Take-Up: Lessons from the Earned Income Tax Credit

Millions of low-income Americans fail to claim tax benefits for which they are eligible, possibly because the rules governing the benefits are extraordinarily complex. I consider efforts to increase tax benefit take-up in light of this complexity. A key fact is that the vast majority of tax filers today prepare their taxes with assisted preparation methods (APMs) like software or professional assistance. APMs eliminate some – but not all – of the barriers to claiming tax benefits for which one is eligible. With respect to claiming the Earned Income Tax Credit (EITC), I argue that most of the relevant complexity is the type that is eliminated by APMs. Consequently, efforts to increase EITC take-up should focus on inducing EITC-eligible individuals to file a tax return using an APM. In contrast, efforts aimed at increasing awareness of the credit (of the type widely employed by governments and nonprofits today) are less likely to be successful, except to the extent they themselves induce an increase in tax filing. Reforms that appear unrelated to a tax benefit may dramatically affect the benefit’s take-up by altering incentives to file a return. I develop these arguments in the context of the EITC, drawing on recent empirical work to support my claims.
Seam segment carving: retargeting images to irregularly-shaped image domains

Image retargeting algorithms aim to adapt the image to the display screen with the goal of preserving the image content as much as possible. However, existing methods and research efforts have mostly been directed towards retargeting algorithms that retarget images to rectangular domains. This significantly hampers its application to broader classes of display devices and platforms for which the display area can be of any origins and shapes. For example, seam carving-based methods retarget images by carving out seams that run from the top to the bottom of the images, and this results in changing the width and therefore aspect ratio of the image without changing the shape of the image boundary in any essential way. However, by carving out appropriately-chosen seam segments, seams that are not required to cut across the entire image, it is then possible to retarget the images to a broader array of image domains with non-rectangular boundaries. Based on this simple idea of carving out the seam segments, the main contribution of this paper is a novel image retargeting algorithm that is capable of retargeting images to non-rectangular domains. We evaluate the effectiveness of the proposed method on a number of challenging indoor and outdoor scene images, and the results demonstrate that the proposed algorithm is both efficient and effective, and it is capable of providing good-quality retargeted images for a variety of interesting boundary shapes.
Resolving Commingling Issues During the Medicolegal Investigation of Mass Fatality Incidents

Abstract By definition, mass fatality incidents result in numerous deaths occurring over a relatively narrow time frame. These events produce complex multidisciplinary investigative challenges. From a medicolegal perspective, investigators seek to recover and examine decedents in a dignified and respectful manner, accurately determine cause and manner of death, perform accurate and efficient identification of victims, provide for the rapid return of victims’ remains to their legal next of kin, and exchange factual and timely information with families in a compassionate manner. Oftentimes, severe fragmentation and commingling of human remains are the byproducts of the causative forces and pose significant challenges to investigators. In a mass fatality context, the overarching tenet regarding commingling is that human remains with no anatomical/physical connection must be considered to be commingled. This principle also applies to remains that are spatially associated but present no valid anatomical connection. From the perspective of the forensic investigator, resolving commingling, and ultimately decedent identification, requires careful management of both the human remains and the data generated during recovery and postmortem examination. This chapter examines effects of fragmentation and commingling on the identification process and discusses the role of triage during the postmortem data collection process as a means to facilitate recognition and reassociation of commingled remains.
The General Theory of Jónsson Classes

The theory of Jonsson classes is the setting of proper generality for the application of the classical principle of back-and-forth induction of Cantor and Hausdorff. Cantor conceived of this principle and used it to prove that the set of rational numbers is described as an ordered set by the following properties: it is countable, without a least or a greatest element, and densely ordered. Hausdorff generalized this result in his theory of η α -sets (studied in § 5 below). Erdős-Gillman-Henriksen proved similar results for the theory of real-closed fields.
Differential Diagnosis of a Patient with Lysosomal Acid Lipase Deficiency: A Case Report.

Background We describe the differential diagnosis of an obese 12-year-old boy of Mexican origin who presented with a 6-year history of abnormal lipid profile and elevated liver transaminase levels. Methods The patient underwent routine clinical testing, an abdominal ultrasound and, ultimately, a liver biopsy. Based on the histologic findings, a serum leukocyte lysosomal acid lipase (LAL) assay and DNA sequencing of the lipase A (LIPA) gene were performed. Results Liver biopsy revealed diffuse microvesicular steatosis with clusters of foamy histiocytes in the lobules and portal areas. Our differential diagnosis included nonalcoholic fatty liver disease; medication-induced hepatotoxicity; glycogenic hepatopathy; medium-chain acyl coenzyme A dehydrogenase or long-chain acyl coenzyme A dehydrogenase deficiency; and lysosomal storage disorders, including Niemann-Pick disease and lysosomal acid lipase deficiency (LAL-D). Serum LAL activity was absent, and DNA sequencing confirmed homozygous mutation in LIPA. Conclusions Although it occurs rarely, LAL-D should be considered in the differential diagnosis of microvesicular steatosis for a timely diagnosis.
Fusing Administrative Data to Combat the Opioid Crisis

Opioid-related overdose deaths remain the leading cause of unintentional injury fatalities in the United States. State lawmakers have responded to this crisis by establishing a regulatory environment that extends various legal protections to persons who may help save the life of someone experiencing an opioid-related overdose. Most states now protect specific parties (e.g., doctors, pharmacists, first responders, laypersons) from civil or criminal liability who prescribe, dispense, possess or administer an opioid antagonist in accordance with the provisions of the state’s law. In addition to standing orders that facilitate access to opioid antagonists, many states offer legal protection to “Good Samaritans” seeking medical and emergency assistance for a person experiencing an overdose. Some states additionally mandate that addiction-treatment services be offered in conjunction with the dispensing of an opioid antagonist, whereas others designate revenue to purchase opiate antagonists or to fund treatment programs. Little is known about the potential impact of such regulatory actions on the opioid crisis. RTI’s Data Fusion Center seeks to meet this need by combining administrative data across sources and systems to inform research and policy. The current paper describes the Data Fusion Center and presents preliminary results from a study that predicts opioid-related overdose deaths based on the existence and strength of opioid-related state laws among 50 states from 2006 to 2016. Policy data were webscraped from state agencies, systematically coded, and associated with target outcomes sourced from CDC. Study findings may help inform lawmakers and stakeholders in prioritizing data-driven policy responses to the opioid crisis.
Calcium Signaling Controls Pathogenic Th17 Cell-Mediated Inflammation by Regulating Mitochondrial Function

Summary Pathogenic Th17 cells play important roles in many autoimmune and inflammatory diseases. Their function depends on T cell receptor (TCR) signaling and cytokines that activate signal transducer and activator of transcription 3 (STAT3). TCR engagement activates stromal interaction molecule 1 (STIM1) and calcium (Ca2+) influx through Ca2+-release-activated Ca2+ (CRAC) channels. Here, we show that abolishing STIM1 and Ca2+ influx in T cells expressing a hyperactive form of STAT3 (STAT3C) attenuates pathogenic Th17 cell function and inflammation associated with STAT3C expression. Deletion of STIM1 in pathogenic Th17 cells reduces the expression of genes required for mitochondrial function and oxidative phosphorylation (OXPHOS) but enhances reactive oxygen species (ROS) production. STIM1 deletion or inhibition of OXPHOS is associated with a non-pathogenic Th17 gene expression signature and impaired pathogenic Th17 cell function. Our findings establish Ca2+ influx as a critical regulator of mitochondrial function and oxidative stress in pathogenic Th17 cell-mediated multiorgan inflammation.

Live-cell Imaging Analysis of Antimycin-Type Depsipeptides via Bioorthogonal Stimulated Raman Scattering Microscopy

Abstract Small-molecule natural products have been an essential source of pharmaceuticals to treat human diseases, but very little is known about their behavior inside dynamic, living human cells. Here, we demonstrate the first structure-activity-distribution study of complex natural products, the anti-cancer antimycin-type depsipeptides, using the emerging bioorthogonal Stimulated Raman Scattering (SRS) Microscopy. Our results show that the intracellular enrichment and distribution of these compounds are driven by their potency and specific protein targets, as well as the lipophilic nature of compounds.
Real Time DC Water Tank Level Control using Arduino Mega 2560

Control engineering is an interdisciplinary field requiring knowledges on math and physics, circuits, sensors, actuator, and microcontrollers (for digital control implementation). It also provides users experiences in testing, simulation and real-time implementation. This paper presents a real-time level control of a laboratory water tank plant demonstrating the essence of control engineering. The objective is to design and apply a PID controller to maintain the water level in a cylinder tank by using Arduino microcontrollers. After plant modelling and device testing, controllers are designed, and the closed-loop system is simulated. Refined controllers are then implemented through Arduino Mega 2560. By comparing the simulation and experimental closed-loop system performances, the difference caused by plant-model mismatch is discussed. The importance of integrating math, physics, and circuits with Arduino programming in embedded control systems is highlighted.
Augmented Consensus Algorithm for Discrete-time Dynamical Systems

Abstract We propose a novel state estimation algorithm for consensus dynamics subject to measurement error. We first demonstrate that with properly tuned parameters, our algorithm attains the same equilibrium value that would be attained using the traditional algorithm based on local state feedback (nominal consensus). We then show that our approach improves consensus performance in a particular class of problems by reducing the state error (i.e., the difference between the agent states and the consensus value). A numerical example compares the performance of the distributed algorithm we propose to that of the traditional local feedback scheme. The results show that the proposed algorithm significantly reduces the state error.
Domestic Spanish handbooks: Language and labor in the American home

In this article I analyze artifacts that teach domestic Spanish, a register of the language meant to facilitate communication between Anglo employers and their Spanish-speaking employees. Comprising a limited range of features, including imperatives, second-person pronouns, and lexical items, domestic Spanish provides its users with a means to overcome the “language barrier” that often characterizes relationships in the domestic sphere. Drawing on the concepts of raciolinguistic ideologies and indexical field, I show how domestic Spanish ultimately works to maintain asymmetrical relationships by constricting the range of social meanings that its use can activate; I also shed light on the ambivalent and often conflicting notions among employers about the Spanish language and its speakers. My analysis lays bare the possible disjuncture between the intention of those who use domestic Spanish and the effect it may have on the relationships that it mediates – a disjuncture that enables its speakers to misrecognize their efforts as benevolent, ignoring the ways that language functions in practices of racial discrimination and social control.

Organophotoredox-Catalyzed Formation of Alkyl-Aryl and -Alkyl C-S/Se Bonds from Coupling of Redox-Active Esters with Thio/Selenosulfonates.

A mild organophotoredox synthetic protocol for forming a Csp3-S/Se bond by reacting widespread redox-active esters with thio/selenosulfonates has been developed. The power of the synthetic manifold is fueled by an unprecedented broad substrate scope and wide functional group tolerance.
Intravenous Thrombolysis in Acute Ischemic Stroke Patients with Unsuspected Infective Endocarditis.

Abstract Objective Infective endocarditis (IE) is considered to be an absolute contraindication for intravenous tissue plasminogen activator treatment (IVtPA) in acute ischemic stroke (AIS). However, during the hyperacute stroke evaluation, the exclusion of IE may be difficult. We sought to report the prevalence of undiagnosed IE in AIS patients who received IVtPA. Methods We reviewed consecutive patients hospitalized at our comprehensive stroke center from January 1, 2014 to March 31, 2019 who received IVtPA for suspected AIS and identified patients diagnosed with IE. Data was abstracted on demographics, medical history, clinical presentation, last known normal (LKN) time, initial National Institutes of Health Stroke Scale (NIHSS), neuroimaging, culture results, and 90 day modified Rankin Scale (mRS). Good functional outcome was defined as mRS ≤ 2. Results Among 1022 AIS patients who received IVtPA, 5 patients (0.5%) were ultimately diagnosed with IE. Among the 5 patients with IE, the mean age was 53.4 years (range, 25-74) and 3 (60%) were female. The majority 4 (80%) were white. Medical risk factors for IE were present in 3 (60%) and included intravenous drug use (1) and dialysis (2). Initial NIHSS was 4.6 (range, 1 to 8). Fever was present on initial presentation in only 1 patient (102.7 F). The mean time from LKN to IVtPA was 3.0 hours (range, 1.9 to 4.4). Vascular imaging showed middle cerebral artery (MCA) occlusion in 4 (80%) and no occlusion in 1 (20%). One patient underwent endovascular thrombectomy. Two patients (40%) developed hemorrhagic complications, including 1 patient who developed subarachnoid hemorrhage due to mycotic cerebral aneurysm rupture. Blood culture results included MRSE (1), Streptococcus viridans (2) and negative (2). TEE in all patients showed vegetations on the mitral valve. No patients had good functional outcomes, and the mean 3 month mRS was 4.8 (range, 3 to 6). The 90 day mortality was 60%. Conclusion In a series of AIS patients who received IVtPA by academic vascular neurologists, the risk of undiagnosed IE was low (0.5%). Fever was not commonly present during initial evaluation in IE presenting with AIS. Despite affecting younger patients with initial mild deficits, AIS patients with IE who received IVtPA had poor functional outcomes.
"Remarkable Stratagems and Conspiracies": How Unscrupulous Lawyers and Credulous Judges Created an Exception to the Hearsay Rule

This essay has a somewhat different goal than the other contributions to this Symposium: rather than considering present-day ethical predicaments, it aims to inspire reflection on an episode in which improper and unprofessional conduct by attorneys contributed to the creation of the law of evidence. In particular, it considers the events that led to the formulation and enactment of a rule that persistently affects the conduct of trials even by the most responsible and ethical lawyers: the hearsay exception codified as Federal Rule of Evidence 803(3).1 The bare bones of the narrative are well-known to nearly every lawyer, as it has formed a staple of the study of the law of evidence since the date of the U.S. Supreme Court’s first decision on the matter in 1892, in Mutual Life Insurance Company of New York v. Hillmon.2 Even the lay public was transfixed by the story in its time; the tale of John Hillmon was the subject
Microstructure and defect gradients in DC and AC flash sintered ZnO

Abstract In this study, the microstructure and defect characteristics of flash sintering under direct current (DC) and alternating current (AC) were investigated and compared for the ZnO system. DC flash sintering resulted in grain size and porosity gradients within the sample, whereas AC flash sintering produced a sample with homogeneous and fine grain size. Raman spectroscopy revealed asymmetric peaks correlated to the lattice disorder. Using the Breit-Wigner-Fano model, the asymmetric peak fitting revealed redistribution of defects within the DC flash sintered ZnO, while the AC flash sintered ZnO had a comparable defect concentration to conventionally sintered ZnO.
User-Controlled Multi-Zone Jacket for Thermal Microclimate Regulation

The ability to control one's personal microclimate allows for customized comfort, reduced energy expenditure, and better human performance. Here we present the design of a multi-zone user-controllable heated jacket. The garment uses a multi-layer textile approach to provide e-textile heating and thermal insulation. Heating zones are controlled by the user through a sleeve-mounted multi-sensor e-textile interface. A custom textile-integrated 3D printed strain-relief support protects the interface and provides a counter-force for manual interaction. The garment is designed for everyday wearability in a physical and aesthetic form intended to blend in with everyday clothing.
Report on Discussion Session: Intermediate Structure, Isobaric Analog and Giant Multipole

Unusual methods for the observation of giant multipoles were discussed at length, in the context of contributions on p.751 and p.755. The former paper was presented by Arvieux; he showed an interpretation of proton inelastic scattering to the 8.88 MeV (2−) state in 16O. His calculations were based on the method of Geramb (cf.p.751); giant multipole resonances appear as intermediate states in a two-step process. The parameters of the E 1 and E 2 resonances determined in this way were in impressive agreement with photonuclear work; in some sense the agreement was too good to convince some sceptical observers. This was also true for similar results obtained previously for 12C. This method appears so promising that I think it would be very useful to have an independent calculation of the effects of giant resonances in inelastic scattering.
Approximate Pressure Distribution in an Accelerating Launch-Vehicle Fuel Tank

A detailed derivation of the equations governing the pressure in a generic liquid-fuel launch vehicle tank subjected to uniformly accelerated motion is presented. The equations obtained are then for the Space Shuttle Superlightweight Liquid-Oxygen Tank at approximately 70 seconds into flight. This generic derivation is applicable to any fuel tank in the form of a surface of revolution and should be useful in the design of future launch vehicles
Prolonged clinical remission in ulcerative colitis beginning during pregnancy: a case report.

Comparative Evaluation of Survey Methods

A researcher has the option of choosing a method from a menu of different methods of doing surveys: face-to-face interview at home or mall-intercept interview, mail survey, online survey, and telephone survey. Each of these methods is characterized by distinct advantages and disadvantages. The major criteria used to evaluate these methods are response time in collecting data, cost of obtaining data per respondent, quality of data obtained from each method, and flexibility in designing the survey, including incorporation of audio/video materials. The mall-intercept interview and web surveys are recommended when the data are needed within a short period of time. Web surveys are also the least expensive method of collecting survey data. On the other hand, the face-to-face interview has been shown to generate the highest quality of data. Face-to-face interviews, followed by web surveys, are also very flexible in terms of adapting the data collection process to the special needs of the research project and the characteristics of survey respondents. Therefore, a researcher has to decide what is important in a given study regarding the four dimensions and choose a method that best meets the desired criteria of the research project.

A review of the records of syphilitic pregnant women treated at the Los Angeles Maternity Service over a ten-year period

Abstract 1. 1. The incidence of syphilis in pregnant women who attended the Los Angeles Maternity Service of the period over the past ten years was found to be 2.04 per cent. 2. 2. There were 4.44 per cent of the pregnant women in this study who presented clinical evidence of syphilis at their first visit to the clinic; 52.73 per cent gave histories suspicious of syphilitic infection. 3. 3. Though the blood Wassermann is the chief reliance in the diagnosis of syphilis in pregnancy and frequently the only evidence of syphilitic infection, there were 41 patients, or 4.23 per cent, in this study in whom there was apparently a nonspecific positive blood Wassermann reaction at some time during pregnancy. 4. 4. The chances of a satisfactory termination of pregnancy in a syphilitic woman are increased with the amount of treatment she is given in pregnancy. 5. 5. A negative blood Wassermann is of great value in determining the probable outcome of pregnancy in a syphilitic woman treated in pregnancy.
Genomic localization of the maize cross-incompatibility gene, Gametophyte factor 1 (ga1)

Gametophyte factors in maize (Zea mays L) mediate pollen-pistil interactions that confer preferential fertilization of some pistil genotypes by pollen carrying compatible alleles. Non-Mendelian segregation ratios caused by game¬tophyte factors have been observed in maize since the early 1920’s. In this study, we mapped the ga1 locus by analyzing segregation distortion and QTL for seed set in recombinant inbred lines from the cross B73 × Hp301. The dent corn parent of this cross, B73, carries ga1, whereas the popcorn parent Hp301 carries the Ga1-s al¬lele conferring preferential fertilization and cross-sterility. High density genotyping-by-sequencing markers were used to delineate the position of ga1 to a 2.6 Mbp region of the B73 reference sequence (AGP version 2). We also mapped ga1 based on its inheritance in backcross between W22 (ga1) and a near-isogenic line carrying Ga1-s on a chromosome segment introgressed from a popcorn variety. The chromosome blocks introgressed from popcorn into W22 were identified with a high-density SNP assay. We created simple sequence repeat markers targeting sequences linked to ga1 to track its inheritance in the W22 backcross populations. Recently, other researchers independently mapped ga1 in crosses of Chinese dent and popcorn lines, and we compared our results to theirs with reference to the B73 reference sequence. All lines of evidence were consistent, with the intervals containing ga1 among all studies overlapping in a 2.2 Mbp interval on chromosome 4 containing 13 predicted genes in the B73 reference sequence.
CLEANING HOUSE - NEW PERSPECTIVES ON HOUSEHOLDS AND ECONOMIC-DEVELOPMENT

Abstract This paper provides a critical review of the recent literature on households and economic development. Three related points are developed: (1) household activities can be analyzed in economic terms, particularly if these terms are broadly defined to encompass such factors as risk and uncertainty; (2) significant differences between the economic position of men, women, and children within the patriarchal household mean that it cannot be treated as an undifferentiated unit of analysis; (3) microeconomic analysis of the household must be situated within a larger structural analysis of gender and age based inequalities and their interaction with class structure and national position within the world capitalist system.
Iowa agritourism consumer profile: demographics, preferences, and participation levels

Agritourism is becoming increasingly popular across the country as agricultural producers open their farms to guests seeking entertainment or educational activities. This study obtained current information from prospective agritourism visitors to identify service and amenity preferences of consumers and explore the current level of participation in Iowa agritourism operations. Data were gathered through completion of a voluntary questionnaire handed out to a random sample of Iowa consumers, over the age of 18, attending the 2008 Iowa State Fair. The questionnaire data were analyzed using descriptive statistics. The information obtained will be used to aid in the continued development of the Iowa agritourism industry. The results of this study illustrate the following conclusions: 1) a large proportion of Iowans have at least some understanding of agriculture and food production; 2) agritourism and other agriculture-related tourism terms are relatively unfamiliar to Iowans; 3) a large proportion of Iowans have previously participated in agritourism activities; 4) word-of-mouth is the most effective form of advertisement for agritourism activities; 5) Iowans are willing to travel and prefer to participate in agritourism activities in the fall with family and friends; 6) consumer motivation to participate in agritourism activities is influenced by the opportunity to purchase fresh products and support local farmers; 7) consumer-perceived importance of agritourism amenities is placed on a convenient location and on-site restrooms; 8) consumers view the availability of fresh products as highly important; 9) a large proportion of Iowans are interested in purchasing Iowa products, particularly fresh vegetables and fruits.
PROTEOLYTIC ACTIVITY OF AEROMONAS CAVIAE

Aeromonas strains produce a variety of virulence factors including proteases. Studies on the kinetics of growth of Aeromonas caviae NRRL B-966 and its proteases suggest that the proteolytic activities are produced throughout the growth phase, with peak level occurring at stationary phase. A. caviae synthesize both intracellular and extracellular proteases with the latter account for major portion of the total activity. Optimum pH for the A. caviae proteolytic activity is at 7.0. A. caviae produces a thermoresistant protease, whose activity is dependent on Mg++ and Ca++ ions. Inhibition of proteolytic activity by phenyl methyl sulfonyl fluoride suggest the presence of a serine protease in A. caviae. Nitrogenous compounds enhance the proteolytic activity while carbohydrates tested in this study inhibit the activity.
