Increase of potential intellectual bandwidth in a scientific community through implementation of an end-user information system

Qureshi, et al. (2002) presented a case study where they used a framework, the intellectual bandwidth model to measure an organization's ability to create value. The model consists of two dimensions, information assimilation and collaboration. The IB model is a useful tool for managers because it enables them to plan solutions to complex business problems and to easily communicate these plans to key individuals. The model can also serve as a guide when making investment decisions. While it is important to increase an organization's intellectual bandwidth, it is equally important to assure that the resulting increase is employed to improve the organization's ability to innovate since, as it has been shown, innovation is the number one creator of organizational wealth (Baum et al., 2000). In this paper we discuss how intellectual bandwidth as proposed by Nunamaker et al. (2001) can be extended beyond the highest level of information assimilation identified in the model, automated sense-making, to ensure implementation of product innovations. To do this we propose adding two new information assimilation features, automated utilization and automated implementation. A real business example from the bioscience industry is presented in order to demonstrate how the IB model with extensions can be used. The study discusses an end-user information system, its current use and its potential to enhance an organization's value-creating capability.
Effects of Externally Generated Dislocations on Brittleness/Ductility of Crystals

Direct interactions of externally generated dislocations with a moving, non-emitting crack tip, have been investigated. Dislocations of the appropriate Burgers vector, initially residing in a strip ahead of the incoming crack tip, are funneled toward the tip, with their motion restricted to the slip plane. Once drawn into the vicinity of the tip, these dislocations inevitably cause local, atomic scale blunting of the tip. The resulting crack trapping process is modelled, resulting in the temperature, crack velocity, and dislocation density dependent, tip toughness.
Comparing the Academic Success of Community College Transfer Students versus Traditional Four Year Students

According to 2014 NMC Horizon Report, the fastest growing jobs in the United Sates in the next 10 years will require college degrees. Community College student enrollment has already increased more than 53% over the last 20 years to attempt to meet this demand (National Association of College and University Business Officers). Some reasons for the increasing trend of students starting their post-secondary education at community colleges may include cost reduction and general preparedness for post-secondary education. Our study analyzes the characteristics of transfers versus traditional students in terms of: GPA, graduation rates and multiple demographic characteristics. This research aims at comparing the academic performance of transfer students versus traditional 4 year students at a singular university, in the areas of graduation rates, timeframes and overall Grade Point Average.

Immunomodulation following burn injury

Severe burn injury is accompanied by suppression of almost all the components of immunity; such suppression undoubedly contributes to infectious complications in the burned patient. There has now been substantial experimental progress made in devising approaches to prevent or minimize these immune defects; however, clinical application is still limited.
Impact of smart home management strategies on expected lifetime of transformer

Low voltage transformers are the most important and expensive assets in a power distribution system. The life time of a mineral-oil-immersed transformer is decreased by raising the Hottest Spot Temperature (HST) in peak hours. This paper assesses the effect of load shaping through households' appliances scheduling on lifetime of a distribution transformer. An IEEE standard transformer is used to estimate transformer aging. This paper provides Demand Response (DR) optimization models to mitigate the thermal stress of transformers caused by overloading. Three smart home management strategies based on DR are compared and evaluated; In the first scenario smart home management is based on preference of customers, then real time pricing is taken into account , and finally the Loss of Life (LOL) of transformers are considered as an objective. To validate the three management approaches, realistic data for household load curves and device parameters are employed. Case studies and results reveal the significant impact of appliances' scheduling strategies on the expected lifetime of distribution transformers.
Contribution of Mindfulness and Emotional Intelligence to Burnout Among Counseling Interns

The authors examined the contribution of mindfulness and emotional intelligence to burnout among counseling interns (N = 380). Results indicated that higher scores on mindfulness and emotional intelligence were related to lower burnout scores. Counselor educators and supervisors should be proactive in helping students to cultivate wellness practices during internships.
Characteristic Longitudinal Transients—Restricted Degrees of Freedom

This chapter discusses the characteristics of longitudinal transients. It discusses longitudinal dynamics by taking into account several simplified motions, for which the equations are so easy that the solutions are almost trivial. The chapter discusses vertical freedom, pitching freedom in straight-line motion, vertical and pitching freedom at constant speed, freedom along the flight path, and vertical and horizontal freedom at constant angle of attack. If α is to be held constant as the motion proceeds, the necessary control deflections could be found from the moment equation. If an observer were flying alongside, he would see the airplane rising and falling—like a mass on a spring. At constant α, on the downswing, the excess speed gives excess lift, and on the upper half, the deficiency of speed gives less lift. The effective spring constant is the change in lift per unit change in altitude.
The Demand Side of the Neoclassical Model

Economics is a discipline whose scientific development has closely reflected the political temper of the times. One would expect this from a subject intimately involved in the welfare of people. As a separate, clearly-defined field of study, economics emerged in the eighteenth century, and from that point until the late nineteenth century was usually called ‘political economy’. The first great figure in political economy was Adam Smith, and all economists from Smith to J. S. Mill (who wrote about ninety years later) are referred to collectively as the ‘classical’ economists. This group of writers had an important common characteristic from the point of view of those that superseded: they all incorporated in their analysis a value theory based upon the labour content in commodities.
Chapter Three: A Metamorphic Movement

The coupling of the nation and the state has been a historic mistake, a vestige of the European colonial history and heritage, carried unthinkingly into the postcolonial history of other nations. As a nation, Iranians have never come anywhere near a democratic state. From their imperial past they collapsed into a colonial encounter with European empires, and from the Constitutional Revolution of 1906–1911 they began dreaming of democracy. That dream has proven a nightmare. From the Qajar absolutism they were delivered to the Pahlavi tyranny, and from the Pahlavi monarchy to the even more tyrannical Islamic Republic. The ruling stats have systematically improved their techniques of domination: The Pahlavis were better in seeking to justify their monarchy than the Qajars were, and the Islamic Republic is even more efficient than the Pahlavis in manufacturing the sham of consent. What we have forgotten, and left entirely un-theorized, is the fact that the nation has also changed, altered, expanded, and opened up its horizons to newer and more enabling vistas. The urgent task at hand is to decouple the nation-state and let the state dwell on its delusion of legitimacy and have a far more accurate conception of the nation and its defiant, successive rebirths.
The Effects of Guided Notes on Pre-lecture Quiz Scores in Introductory Psychology

Guided notes covering lectures have been shown to improve note quality and increase scores on quizzes covering lecture material. We sought to determine whether guided notes would also be beneficial in helping students prepare for quizzes covering assigned readings. We evaluated the efficacy of guided notes for reading assignments on undergraduates’ scores on quizzes covering reading material during one semester of an Introductory Psychology course. Guided notes produced statistically significant improvements in quiz scores and note accuracy. Together with previous literature, our results suggest that guided notes may be an effective component of college courses.
Structural and Mechanical Properties of Cocoons of Antherina suraka (Saturniidae, Lepidoptera), an Endemic Species Used for Silk Production in Madagascar

Antherina suraka Boisduval (Saturniidae, Lepidoptera) produces a silken cocoon that has been the focus of efforts to create a commercial wild silk industry in Madagascar. In this study, structural and mechanical properties of the cocoon of A. suraka from two sites were measured and compared to the cocoon of Bombyx mori L. (Bombycidae, Lepidoptera) the world's most common source for silk. Results of environmental scanning electron microscopy and mechanical testing showed that the silk sheet of A. suraka cocoon is less compact, with greater thickness and lower tensile strength and stiffness than that of B. mori Confirming these results, stiffness and cell and thread density were found to be negatively correlated with thickness, and the cell and thread volumes were positively correlated with thickness. Antherina suraka showed no major differences between silk sheets from Kirindy and Isalo sites in either structural or mechanical properties, except for mean cell volume, which was greater in cocoons from Kirindy. Comparison between the two layers forming the cocoon showed that the inner layer has greater elastic modulus, denser silk distribution and lower porosity. Cocoons from both Kirindy and Isalo are suitable for sericulture. Although the inner layer of cocoon silk is of higher quality than the outer layer, the fact that both layers are of great but lower tensile strength than B. mori silk suggests that the current practice of sewing the two layers together for making one single layer fabric should be continued in efforts to produce a commercially viable product.
Impact of Clonidine on Patient and Family Experiences with Difficult EEGs (P1.350)

OBJECTIVE: Improve family satisfaction and EEG quality with clonidine for challenging EEGs. BACKGROUND: EEG set-up in pediatric epilepsy patients can be challenging particularly with co-morbid behavioral and developmental disorders due to difficulty with lead placement, pulling leads off, or motion artifact. A failed or poor quality EEG may delay diagnosis or cause unnecessary treatment. In our institution, challenging EEG set-ups have resulted in failed studies and personnel injury. Clonidine is used for impulsivity and aggression in ambulatory settings as well as premedication prior to procedures. Clonidine use for EEG has not been validated or standardized. Our quality improvement project addresses the following: EEG quality improvement in children with known behavioral disorders who receive clonidine prior to EEG set-up and improvement in patient/family experience with clonidine administration. METHODS: For this QI project, we reviewed routine or long-term video EEGs from 13 children who received clonidine, and compared the results to previous EEGs in those children without clonidine when available. We also surveyed families’ experiences with clonidine prior to EEG set-up. RESULTS: All patients tolerated the clonidine without need for intervention. In children who received clonidine, 85[percnt] or 11/13 had a good quality EEG defined by the presence of sleep, wakefulness, and motion artifact absence. Of those, 10 who had prior studies without clonidine, only 30[percnt] had good quality EEGs. The majority of families reported a good experience with pre-EEG clonidine, and would use it again for future EEGs. CONCLUSIONS: Clonidine is effective at improving patient/family satisfaction and EEG quality in children with behavioral and developmental disorders when EEG set-up is challenging. This may be a useful adjunct in resource limited institutions. Based on the results, we developed a standardized procedure for children receiving clonidine for EEG set-up to ensure safety and appropriate monitoring.

Dentate Mossy Cell and Pattern Separation

Three studies by Danielson et al. (2017), GoodSmith et al. (2017), and Sensai and Buzsaki (2017) distinguish in vivo firing properties of dentate mossy cells from granule cells during behavior. Robust spatial remapping of mossy cells, in contrast to sparse firing of granule cells, suggests differential involvement in pattern separation.
The Corneal Epithelial Barrier and Its Developmental Role in Isolating Corneal Epithelial and Conjunctival Cells From One Another.

Purpose During development, the corneal epithelium (CE) and the conjunctiva are derived from the surface ectoderm. Here we have examined how, during development, the cells of these two issues become isolated from each other. Methods Epithelia from the anterior eyes of chicken embryos were labeled with the fluorescent, lipophilic dye, 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI). DiI was placed on the epithelial surface of the developing anterior eye and its diffusion was monitored by fluorescence microscopy. Concomitant morphologic changes in the surface cells of these epithelial were examined by scanning electron microscopy. Immunofluorescence was used to analyze the expression of cytokeratin K3, ZO-1, N-cadherin and Connexin-43 and the function of gap junctions was analyzed using a cut-loading with the fluorescent dye rhodamine-dextran. Results Prior to embryonic day 8 (E8), DiI placed on the surface of the CE spreads throughout all the epithelial cells of the anterior eye. When older eyes were similarly labeled, dye diffusion was restricted to the CE. Similarly, diffusion of DiI placed on the conjunctival surface after E8 was restricted to the conjunctiva. Scanning electron microscopy showed that developmentally (1) physical separations progressively form between the cells of the CE and those of the conjunctiva, and (2) by E8 these separations form a ring that completely encompasses the cornea. The functional restriction of gap junctions between these tissues did not occur until E14. Conclusions During ocular development, a barrier to the diffusion of DiI forms between the contiguous CE and conjunctiva prior to the differential expression of gap junctions within these tissues.
A bacterial pterin deaminase.

Publisher Summary This chapter describes the bacterial pterin deaminase. In the standard assay, the mixture contains 0.05 ml of pterin carboxylic acid, 0.8 ml of phosphate buffer, and 0.02 to 0.15 ml of enzyme in a final volume of 1.0 ml. Incubation is carried out at 23° in a 1-ml Beckman quartz cuvette with a light path of 1.00 cm. Reaction is begun by the addition of enzyme, and readings of optical density are taken every 3 minutes thereafter. The control cuvette contains buffer and enzyme, but no pterin carboxylic acid. With crude preparations light measurement at 360 mμ is employed. However, with more purified fractions of the deaminase, it is possible to follow the course of the reaction at 290 mμ, the wavelength at which there is observed the largest AE value between substrate and product. The most satisfactory conditions for storage of enzyme fractions were found to be at pH 9.0 in 0.1 M Tris buffer at 0°. Under such conditions pterin deaminase activity remained almost unchanged for several weeks. The pH optimum for pterin deaminase activity occurs between pH 6.3 and 6.7. Although the reaction proceeds in the complete absence of phosphate, the rate of deamination is slightly faster in phosphate than in Tris buffer.
Approaches to the Hip

Proximal femur fractures are a common injury and almost always require surgical intervention. Although many fracture types can be reduced indirectly, an open approach may be required to achieve an anatomic reduction. In addition, approaches to the proximal femur also need to be useful for an arthroplasty procedure, should one be required.
Development of a motion controlled robotic arm

In this paper, an inexpensive, a lightweight and easily controlled robotic arm with human interface is developed. The developed robotic arm is fully functional and accurately reacts to the movements from the user. The human user wears 2 accelerometers on his/her arm. These accelerometers relay both position and speed vector information to the robotic arm. The user also wears a glove that controls the flex sensor which gives readings to the claw. The robotic arm is on a fully mobile base that moves the arm from location to location in any given room. The research methodology and design are introduced before the robot system is realized and tested. Finally, conclusions are given and future improvements are discussed.
Scheduling and Resource Allocation in 802.11ax

802.11ax introduces OFDMA to WiFi. It thus enables multiplexing users/user groups in the frequency domain. WiFi networks usually operate in a multipath environment which generates a frequency selective channel. Hence, the capacity of a user/user group changes over different subcarriers. A good scheduling and resource allocation scheme can maximize the sum rate by allocating users and user groups on subcarriers based on their CSI and other system considerations. In this paper we investigate how to optimally assign users and user groups to subcarriers with the goal of maximizing the user sum rate in the context of 802.11ax. We introduce a novel divide and conquer based algorithm which we prove to be optimal under the assumption that a user can be assigned to more than one resource unit (RU) which consists of one ore more subcarriers. This serves as a tight upper bound on the actual problem where users/user groups can be assigned to a single RU only per the 802.11ax standard. We then introduce two practical algorithms for the actual problem, a greedy one and a recursive one which jointly splits the bandwidth into RUs and schedules users on them. Extensive simulations comparing the performance of the aforementioned algorithms establish that our practical schemes achieve very good performance in all studied scenarios.
Feasibility study of minimally trained medical students using the Rural Obstetrical Ultrasound Triage Exam (ROUTE) in rural Panama.

Background Maternal and infant mortality rates reported in rural Panama are greater than those in urban regions. Bocas del Toro is a region of Panama inhabited by indigenous people at greater risk for pregnancy-related complications and deaths due to geographic isolation and limited access to health care. Portable ultrasound training programs have recently been implemented in low-resource settings to increase access to diagnostic imaging. The goal of this study is to determine the feasibility of teaching first-year medical students the Rural Obstetrical Ultrasound Triage Exam (ROUTE) to help identify pathology in pregnant women of the Bocas del Toro region of Panama. Methods Eight first-year medical students completed ROUTE training sessions. After training, the students were compared to professional sonographers to evaluate their accuracy in performing the ROUTE. Students then performed the ROUTE in mobile clinics within Bocas del Toro. They enrolled women pregnant in their 2nd or 3rd trimesters and measured biparietal diameter, head circumference, amniotic fluid index, fetal lie and placental position. Any abnormal measurement would be further analyzed by the lead physician for a potential hospital referral. Results A total of 60 women were enrolled in the study. Four women were detected as having a possible high-risk pregnancy and thus referred to a hospital for further evaluation. Conclusion Based on our data, first-year medical students with additional training can use the ROUTE to identify complications in pregnancy using ultrasound in rural Panama. Additional studies are required to determine the optimal amount of training required for proficiency.
Piaget’s Cognitive-Developmental Theory

The essence of Piaget’s theory can be captured in four themes. (1) Of the three possible epistemological stances regarding the origin of knowledge (i.e., nativism, empiricism, and constructivism), constructivism is the most viable and compelling alternative. (2) The development of children’s thinking can be described as a progression through four levels or stages of thought. (3) Of the various epistemological stances regarding the nature of knowledge (e.g., structuralism, functionalism, behaviorism, and connectionism), structuralism and functionalism are the most viable and compelling alternatives. (4) Of the four factors that explain the changes in thought that occur over time (i.e., biological maturation, physical experience, social exchange, and equilibration), equilibration is the most significant. These themes resonated with some scholars but prompted many others to compile evidence and arguments against Piaget’s account. Although few developmentalists currently conduct research to support or extend this account, it is still highly influential.

10,12 Conjugated Linoleic Acid-Driven Weight Loss Is Protective against Atherosclerosis in Mice and Is Associated with Alternative Macrophage Enrichment in Perivascular Adipose Tissue

The dietary fatty acid 10,12 conjugated linoleic acid (10,12 CLA) promotes weight loss by increasing fat oxidation, but its effects on atherosclerosis are less clear. We recently showed that weight loss induced by 10,12 CLA in an atherosclerosis-susceptible mouse model with characteristics similar to human metabolic syndrome is accompanied by accumulation of alternatively activated macrophages within subcutaneous adipose tissue. The objective of this study was to evaluate whether 10,12 CLA-mediated weight loss was associated with an atheroprotective phenotype. Male low-density lipoprotein receptor deficient (Ldlr−/−) mice were made obese with 12 weeks of a high-fat, high-sucrose diet feeding (HFHS: 36% fat, 36% sucrose, 0.15% added cholesterol), then either continued on the HFHS diet with or without caloric restriction (CR), or switched to a diet with 1% of the lard replaced by either 9,11 CLA or 10,12 CLA for 8 weeks. Atherosclerosis and lipid levels were quantified at sacrifice. Weight loss in mice following 10,12 CLA supplementation or CR as a weight-matched control group had improved cholesterol and triglyceride levels, yet only the 10,12 CLA-treated mice had improved en face and aortic sinus atherosclerosis. 10,12 CLA-supplemented mice had increased lesion macrophage content, with enrichment of surrounding perivascular adipose tissue (PVAT) alternative macrophages, which may contribute to the anti-atherosclerotic effect of 10,12 CLA.
Patient Centered Communication and E-Health Information Exchange Patterns: Findings From a National Cross-Sectional Survey

This paper aimed to determine whether there was a connection between patient’s perception of communication with their doctors in the visit and their use of online health information exchange using a nationally representative survey. We used the data from the Health Information National Trends survey pooled HINTS4 Cycle 4 data and assessed outcomes using logistic regression modeling composite communication scores as a continuous variable. We weighted participants to create population-level estimates. We adjusted for age, gender, race, and census region. The 3677 patients were included in the analysis who had an outpatient visit within the previous 12 months. In unadjusted analysis and analysis adjusted for demographic factors, patients who experienced higher communication scores were more likely to use online health information exchange with their providers. In unadjusted analysis, patients had 0.04 higher odds of interest in receiving appointment reminders from health care providers electronically (OR = 1.04 and $p=0.01$ ) and 0.03 higher odds of interest in receiving general health tips (OR = 1.03 and $p=0.04$ ) for every score increase in the communication summary score. In adjusted model, for each score increment in the communication score, patients were 7% more inclined to receive appointment reminders ( $p ), 4% more inclined to receive general health tips ( $p=0.02$ ), and 4% more likely to exchange information about lifestyle behaviors ( $p=0.02$ ). Findings suggest that the quality of the communication in the visit might increase use of informatics tool to exchange health information.
Stereotactic ablative radiotherapy (SABR) in early stage non-small cell lung cancer: Comparing survival outcomes in adenocarcinoma and squamous cell carcinoma.

Abstract Purpose Recent retrospective studies have demonstrated mixed results regarding the histologic association of squamous cell carcinoma (SCC) with reduced overall survival in patients with early-stage non-small cell lung cancer (ES-NSCLC) treated with stereotactic ablative radiotherapy (SABR). Methods We queried the National Cancer Database (NCDB) for ES-NSCLC (T1-2N0, Stage I-IIA) patients with SCC or adenocarcinoma (ADC) treated with SABR. Univariable and multivariable analyses identified characteristics predictive of overall survival. Cox proportional hazard ratios with propensity adjustment were used to mitigate indication bias between the two histologic arms. Results Ultimately 15,110 ES-NSCLC patients with either ADC (n = 8,924) or SCC (n = 6,186) were eligible for analysis. Univariable analysis demonstrated a median overall survival of 44 months and 33 months (p Conclusion SCC histology was an independent prognosticator of worse survival in patients with ES-NSCLC treated with SABR, thus corroborating the results of previous studies. Randomized, prospective studies are needed to further validate these findings.

Evolution of fenestrated/branched endovascular aortic aneurysm repair complexity and outcomes at an organized center for the treatment of complex aortic disease

Abstract Background Fenestrated/branched endovascular aneurysm repair (F/BEVAR) volume has increased rapidly, with favorable outcomes at centers of excellence. We evaluated changes over time in F/BEVAR complexity and associated outcomes at a single-center complex aortic disease program. Methods Prospectively collected data of all F/BEVAR (definition: requiring ≥1 fenestration/branch), procedures performed in an institutional review board-approved registry and/or physician-sponsored investigational device exemption trial (IDE# G130210), were reviewed (11/2010-2/2019). Patients were stratified by surgery date into thirds: early experience, mid experience, and recent experience. Patient and operative characteristics, aneurysm morphology, device types, perioperative and midterm outcomes (survival, freedom from type I or III endoleak, target artery patency, freedom from reintervention), were compared across groups. Results For 252 consecutive F/BEVARs (early experience, n = 84, mid experience, n = 84, recent experience, n = 84), 194 (77%) company-manufactured custom-made devices, 11 (4.4%) company-manufactured off-the-shelf devices, and 47 (19%) physician-modified devices, were used to treat 5 (2.0%) common iliac, 97 (39%) juxtarenal, 31 (12%) pararenal, 116 (46%) thoracoabdominal, and 2 (0.8%) arch aneurysms. All patients had follow-up for 30-day events. The mean follow-up time for the entire cohort was 589 days (interquartile range, 149-813 days). On 1-year Kaplan-Meier analysis, survival was 88%, freedom from type I or III endoleak was 91%, and target vessel patency was 92%. When stratified by time period, significant differences included aneurysm extent (thoracoabdominal, 33% early experience, 40% mid experience, and 64% recent experience; P Conclusions Despite increasing repair complexity, there has been no significant change in perioperative complications, overall survival, or target artery patency, with favorable outcomes overall. Type I or III endoleaks remain a significant limitation, with increased incidence as the number of branch arteries incorporated into the repairs has increased.

The reaction of propylene to propylene-oxide on CeO2: An FTIR spectroscopy and temperature programmed desorption study

The potential of CeO2 as an epoxidation catalyst is studied for the reaction of propylene with hydrogen peroxide (H2O2) by Fourier transform infrared (FTIR) spectroscopy and temperature programmed desorption (TPD). Adsorption and decomposition of H2O2 and propylene oxide (PO) are also explored to determine their surface chemistry and thermal stability. Hydrogen peroxide adsorbed dissociatively on CeO2 forming adsorbed peroxo (O-O) species, as observed through vibrational features at 890 cm-1 and (830-855) cm-1 (FTIR). The signal at 890 cm-1 disappeared when a pulse of propylene was passed through the catalyst, and at the same time, adsorbed PO was observed (a sharp IR mode at 827 cm-1; ring deformation). The reaction between gas phase propylene and adsorbed peroxide species suggested the Eley-Rideal type mechanism. The absence of a ring opening reaction of PO at room temperature may indicate that CeO2 can be a suitable oxide for epoxidation of hydrocarbons. PO started to decompose above 323 K, as observed from FTIR and TPD results. TPD spectra of PO show its desorption at 365 K, with a small fraction decomposing into acetaldehyde and formaldehyde due to partial decomposition, while CO2 and CO are released at higher temperatures. Adsorbed acetate, formate, and carbonate species, formed due to further reactions of aldehydes, are observed during the thermal reaction (FTIR).
Evaluation of andexanet alfa and four-factor prothrombin complex concentrate (4F-PCC) for reversal of rivaroxaban- and apixaban-associated intracranial hemorrhages.

Background/objective Before approval of andexanet alfa, off-label treatment with 4-factor prothrombin complex concentrate (4F-PCC) was often utilized for the management of life-threatening hemorrhages associated with oral factor Xa inhibitors. We evaluated the operational processes and outcomes of patients with oral factor Xa inhibitor-associated intracranial hemorrhages (ICH) treated with andexanet alfa or 4F-PCC. Methods We performed a retrospective, single-center case series of rivaroxaban or apixaban-associated ICH between 2016-2019 treated with andexanet alfa or 4F-PCC. Good or excellent hemostatic effectiveness, good functional outcome (Glasgow Outcome Score [GOS]> 3) at hospital discharge, and incidence of thrombosis within 30 days were reported. Results Eighteen patients were included in the andexanet alfa cohort and 11 in the 4F-PCC cohort. Excellent or good hemostasis occurred in 88.9% of andexanet alfa-treated patients and 60% of 4F-PCC-treated patients. Good functional outcome on discharge occurred in 55.6% of andexanet alfa-treated patients and 9.1% of 4F-PCC-treated patients. Thrombotic complications occurred in 16.7% of andexanet alfa-treated patients and 9.1% of 4F-PCC-treated patients. Median order-to-administration time was 1.1 hours [0.8-1.4] versus 0.5 hours [0.1-0.8] in the andexanet alfa and 4F-PCC group, respectively. The median cost of therapy was $29970/patient versus $6925/patient in the andexanet alfa and 4F-PCC group, respectively. Conclusions We observed higher rates of occurrence of good or excellent hemostasis and GOS > 3 on hospital discharge and increased incidence of thrombosis in patients who received andexanet alfa compared to 4F-PCC for oral factor Xa inhibitor reversal. However, patients receiving 4F-PCC had lower pre-reversal Glasgow Coma Scale (GCS)score and larger pre-reversal ICH volume.
Intimate Partner Violence Among Older LGBT Adults: Unique Risk Factors, Issues in Reporting and Treatment, and Recommendations for Research, Practice, and Policy

Although intimate partner violence (IPV) among older LGBT adults is associated with significant negative consequences—including mental and physical health problems, increased hospital and nursing home admissions, and a 300% increased risk of mortality—it remains an overlooked and understudied public health issue. This chapter reviews the limited body of research available regarding IPV among older LGBT adults including its estimated prevalence, risk factors (increased age, disability status, living in poverty), associated myths (caregiver stress drives IPV; older same-sex female partners do not engage in violent behavior), unique presentations (threatening to force a partner into a nursing home in which they are afraid to disclose their LGBT status), unique challenges (a lack of national survey data; sexual minority stress; life-long stigma; health disparities; limited legal protection), and barriers to assessment and treatment (inadequate responses from law enforcement; a lack of age- and LGBT-friendly shelters). Recommendations for future research, culturally competent practice, and policy are also presented.
Static Analysis of Voltage Stability

The static analysis method of voltage stability is to capture the system state on different time sections along the time track. By assuming that the differential of the system state variables on the section is zero, the differential-difference-algebraic equations describing the nonlinear dynamic power system are simplified to pure algebraic equations. Since the early voltage instability accidents are mostly the medium and long-term voltage instability processes, which have a long time span and are usually caused by slow load growth or system output power transfer, the static analysis method has become the mainstream of voltage stability research for a long period of time.

Photography-based real-time long-wave infrared scattering estimation technique

The scattered light distribution of surfaces in the long-wave infrared (λ∼8−12µm) is measured using a small set of thermal camera images. This method can extract scatter patterns considerably faster than standard laboratory bidirectional reflectance distribution function measurements and is appropriate for passive homogeneous surfaces. Specifically, six images are used in this study, each taken with respect to a thermal light source at an angle ranging from 10° to 60° to the normal of the surface. This data is deconvolved with the shape of the light source to estimate the scattering pattern. Both highly specular (black Masonite) and diffuse (painted drywall) surfaces are tested. Errors between the estimated scattering distribution and a directly measured one using a goniometer stage and quantum-cascade laser (QCL) are less than or equal to 3% except for extremely specular surfaces where viable QCL measurements cannot be made due to the increased relative contribution of speckle noise.
Simplified carriage of MPEG immersive video in HEVC bitstream

Immersive video enables end users to experience video in a more natural way interactively with viewer motion from any position and orientation within a supported viewing space. MPEG Immersive Video (MIV) is an upcoming standard being developed to handle the compression and delivery of immersive media content. It extracts only needed information in the form of patches from a collection of cameras capturing the scene and compresses with video codecs such that the scene can be reconstructed at the decoder side from any pose. A MIV bitstream is composed of non-video components carrying view parameters and patch information in addition to multiple video data sub-bitstreams carrying texture and geometry information. In this paper, we describe a simplified MIV carriage method, using an SEI message within a single layer HEVC bitstream, to take advantage of existing video streaming infrastructure, including legacy video servers. The Freeport player is built on the open-source VLC video player, a GPU DirectX implementation of a MIV renderer, and a face tracking tool for viewer motion. A prerecorded demonstration of Freeport player is provided.
Social Justice in Library and Information Science

While pursuing graduate degrees in library and information science (LIS), it is hoped that students will learn the basics necessary for competent, inclusive, and caring professional practice. This panel will explore how social justice topics and techniques can be integrated in LIS through a variety of contexts including curricular, extra-curricular professional development, and research. Social justice integration creates opportunities for students to gain a more holistic and inclusive perspective on the relationships between people, information, and technology, with the ultimate potential of shaping a more just society. The panel topics approach social justice in LIS from a range of professional experiences, drawing on concrete examples, interventions, and historical cases.
The Entanglements of Nathaniel Hawthorne: Haunted Minds and Ambiguous Approaches

Nathaniel Hawthorne, celebrated in his own day for sketches that now seem sentimental, came only gradually to be fully appreciated for what his friend Herman Melville diagnosed as the 'power of blackness' in his fiction - the complex moral grappling with sin and guilt. By the 1850s, Hawthorne had already been accepted into the American canon, and since then, his works - especially 'The Scarlet Letter' - have remained ubiquitous in American culture. Along with this has come an explosion of Hawthorne criticism, from New Criticism, New Historicism, and Cultural Studies to queer theory, feminist scholarship, and transatlantic criticism, that shows no signs of slowing. This book charts Hawthorne's canonization and the ongoing critical discourse, drawing on two senses of 'entanglement.' First the sense from quantum physics, which allows us to see what were once seen as strict dualisms in Hawthorne as more complex relations where the poles of the would-be dualities play off of and affect each other; second, the sense of critics being tangled up in, caught up in, Hawthorne the man and his work and in previous critics' views of him. Charting the course of Hawthorne criticism as well as his place in popular culture, this book sheds light also on the culture in which his reception has occurred.

Hysteroscopic Myomectomy of FIGO Type 2 Leiomyomas Under Local Anesthesia: Bipolar Radiofrequency Needle-Based Release Followed By Electromechanical Morcellation.

Abstract Objective To demonstrate a technique designed to expand the capabilities of hysteroscopic intrauterine morcellators to deep type 1 and type 2 lesions. The technique comprises "release" of the tumor using a bipolar radiofrequency needle, followed by dissection and extraction with an electromechanical morcellator, all under local anesthesia. Design Description of technique using images and video (Canadian Task Force classification Class III). Setting Office uterine procedure and imaging center; academic medical center. Intervention Following the administration of local anesthesia and access to the endometrial cavity with a 5.5-mm-o.d. hysteroscopic sheath with a 5 Fr operative channel, a 5 Fr bipolar needle electrode system is used to circumscribe the leiomyoma and enter the pseudocapsule, thereby "releasing" the lesion. Blunt dissection is performed as appropriate and then the system is switched to a hysteroscopic morcellating system (MyoSure; Hologic, Bedford, MA), which is then used to further dissect and remove the target lesion with electromechanical morcellation. Conclusion The development of intrauterine morcellators has facilitated the performance of hysteroscopic myomectomy, especially under local anesthesia, but the side aperture–based design of the systems limits their use in International Federation of Gynecology and Obstetrics (FIGO) type 1 and 2 tumors, particularly those located at the uterine fundus. This technique, based in part on a previously published technique of leiomyoma release, improves access of the electromechanical morcellator to leiomyomas that previously were inaccessible, and minimizes myometrial trauma by dissecting the tumor via the relatively avascular pseudocapsule.

Measuring the vulnerability of interconnection networks in embedded systems

Studies of the fault-tolerance of graphs have tended to largely concentrate on classical graph connectivity. This measure is very basic, and conveys very little information for designers to use in selecting a suitable topology for the interconnection network in embedded systems. In this paper, we study the vulnerability of interconnection networks to the failure of individual links, using a set of four measures which, taken together, provide a much fuller characterization of the network. Moreover, while traditional studies typically limit themselves to uncorrelated link failures, our model deals with both uncorrelated and correlated failure modes. This is of practical significance, since quite often, failures in networks are correlated due to physical considerations.
Various results concerning set input-to-state stability

Regarding the input-to-state stability (ISS) property, we extend it to arbitrary closed invariant sets various results which were previously known for the case of equilibria. In particular, we show the equivalence between stabilizability and feedback equivalence to ISS systems. In addition for the compact attractor case, we provide Lyapunov and dissipation-theoretic characterizations, and we relate this case to the notion of "practical" ISS (ISpS), a notion which appears in the context of small-gain theorems.
Beam Emittance and Lattice Design

The task of lattice design for proton and ion beams can be concentrated to a purely particle beam optics problem. Transverse as well as longitudinal emittances of such beams are constants of motion and therefore do not depend on the particular design of the beam transport or ring lattice. This situation is completely different for electron and positron beams in circular accelerators where the emission of synchrotron radiation determines completely the particle distribution in six-dimensional phase space. The magnitude and characteristics of synchrotron radiation effects can, however, be manipulated and influenced by an appropriate choice of lattice parameters and characteristics. We will discuss optimization and scaling laws for the transverse beam emittance of electron or positron beams in circular accelerators. A similar discussion on the manipulation of longitudinal phase space will be postponed to Vol. II due to the need to include nonlinear beam dynamics.
MEDUSA: A GLIMPSE OF THE WOMAN IN FIRST AMENDMENT LAW

In this Article, I attempt to solve a First Amendment puzzle by turning to a surprising source. Here is the First Amendment puzzle: why would the Supreme Court offer robust First Amendment protection to non-obscene pornographic film, while relegating live erotic dance, far less sexually explicit, to the very "perimeter" of First Amendment protection? I suggest that one way to understand this puzzle can be found in the ancient myth of Medusa, the monster Freud interpreted as standing for the castrated female genitals. A direct confrontation with Medusa's stare was deadly. But Perseus slayed Medusa by outsmarting her: he looked at her only in the reflection of his shield, thereby transforming her into the passive object of his gaze. I interpret Perseus's shield as a precursor of pornographic film. In my view, live erotic performance, in which the dancer interacts with the audience and claims her own role as a First Amendment speaker, conjures up some of the threat of the unmediated stare of Medusa. In contrast, pornographic film, like Perseus's shield, tames the monstrous threat of the woman's direct stare. Thus, I read the Court's puzzling distinction as bound up in anxieties about castration, the female gaze, and the possibility of female agency and speech that the gaze symbolizes. Ultimately, my goal in this article is to show how longstanding, indeed mythic, cultural assumptions about gender, sexuality and representation penetrate the Court's doctrinal analysis.
