Auto Theft: A site-survey and analysis of environmental crime factors in Atlantic City, NJ

Recent environmental criminology literature has indicated a need for criminologists to focus on site-level, as well as community-level, variables that influence property crimes. The current study involves the use of this approach to take a closer look at environmental characteristics of single and repeat victimization auto theft locations in Atlantic City. A random sample of single auto theft locations were matched to repeat locations based on proximity, zoning (commercial or residential) and size of the parking structure. Five variables were measured using indices, Watchers, Activity Nodes, Location, Lighting and Security. Multivariate logistic regression was conducted using the W.A.L.L.S. variables. Findings indicate that in commercial areas, locations that had poor environmental designs and those located near activity nodes were more likely to suffer repeat auto theft victimization.

Graphics processing unit-accelerated real-time compressive sensing spectral domain optical coherence tomography

In this paper, we systematically demonstrate two real-time CS SD OCT systems based on a conventional desktop having three GPUs. The first one takes fast Fourier transform (FFT) as the sensing technique and under-sampled linear wavenumber spectral sampling as input data, while the second one uses non-uniform fast Fourier transform (NUFFT) and under-sampled nonlinear wavenumber spectral sampling, respectively. The maximum reconstruction speed of 72k and 33.5k A-line/s were achieved for these two systems, respectively, with A-scan size 2048. It is >100 times faster than the C++ implementation and >400 times faster than the MATLAB implementation. Finally, we present real-time dispersion compensated image reconstruction for both systems.
Percolation-enhanced supersolids in the extended Bose-Hubbard model

We theoretically study the stability of lattice supersolid states in the extended Bose-Hubbard model with bounded spatial disorder. We construct a disorder mean-field theory and compare with quantum Monte Carlo calculations. The supersolid survives weak disorder on the simple cubic lattice. We also find that increasing disorder strength can transform a lattice solid into a supersolid as it tends to percolate through the disorder landscape.

Feasibility of combined EUS-FNA and ERCP for obstructive jaundice from presumed pancreatic malignancy.

The management of patients with pancreatic cancer begins with confirmation of the diagnosis by cytology, which is followed by accurate preoperative staging and biliary drainage. Endoscopic ultrasonography with fine-needle aspiration (EUS–FNA) followed by endoscopic retrograde cholangiopancreatography (ERCP) helps to achieve these goals and primes the patient for various treatment options. We discuss the findings of a study by Ross and colleagues that aimed to determine the feasibility and outcomes of combining EUS–FNA and therapeutic ERCP in a single session. The authors concluded that combined EUS–FNA and ERCP was technically feasible, and could safely and effectively achieve a diagnosis and biliary drainage. The adverse event rate was acceptable; pancreatitis was the most common complication. Such a one-step approach is, therefore, beneficial and calls for the founding of well-equipped units with adequately skilled endoscopy and support staff.
Solvent Polarity at Polar Solid Surfaces: The Role of Solvent Structure

Resonance enhanced second harmonic spectra of the chromophore 4-aminobenzophenone (4ABP) were recorded at different solid/liquid interfaces. The solid substrates were hydrophilic silica and the solvents varied in size, shape and dielectric properties. Solvatochromic comparisons between SHG spectra of adsorbed 4ABP and excitation spectra of 4ABP in bulk solution reveal how solvent−substrate interactions and solvent structure alter interfacial solvent polarity from bulk solution limits. Not surprisingly, weakly associating systems consisting of polar substrates and nonpolar solvents are more polar than bulk solution, although there exist subtle, solvent-dependent differences in the strength of interfacial solvent−solute interactions. These differences are attributed to a solvent's ability to pack against a rigid wall. Measurements of solute orientation at weakly associating interfaces supports a model in which the solute experiences multiple interactions with the substrate and adopts an orientation that is ...
Stereoselective determination of trihexyphenidyl in human serum by LC-ESI-MS.

The antiparkinsonian drug trihexyphenidyl (THP) is currently manufactured and administered as a racemate. However, stereochemistry can play significant role in the drug's pharmacokinetics, biotransformation, metabolism, interaction with cellular and tissue components and overall effect on human body. It is necessary to consider such a drug as a mixture of two compounds (drug enantiomers), with their own effect on the human body. The present paper describes a simple and sensitive LC-MS method for the stereoselective determination of THP in human serum. In this study, the sample was prepared by a solid-phase extraction (SPE) procedure. The enantiomer separation was done using native beta-cyclodextrin stationary phase LC column. The combination of ESI-MS detection and SPE showed excellent sensitivity and selectivity of the method. The limits of detection of 95%.
Improving reliability through fault propagation scope in embedded systems

In this work, we propose a technique based on task recomputation in order to improve reliability without incurring any performance degradation in embedded systems. The technique focuses on recomputing the task using the slack available on idle processors thereby maximizing the usage of the processing elements. In conjunction with task recomputation, we employed two metrics called as Fault Propagation Scope (FPS) and Degree of Criticality (DoC). Our technique, named as Hybrid Recomputation, improves the reliability even as the scope for fault propagation is reduced. The fault propagation scope of the task graph is reduced by incorporating the fault propagation scope of each task and its degree of criticality into the scheduling algorithm. Our technique of hybrid recomputation is analyzed using various automatically generated task graphs using TGFF. The experimental results clearly indicate the viability of the proposed approach under different latency constraints.
Differential effects of morphine, dopamine and prolactin administered iontophoretically on arcuate-ventromedial hypothalamic neurons

The effect of iontophoretically applied morphine, dopamine and prolactin on the spontaneous, extracellular electrical activity of arcuate-ventromedial hypothalamic neurons was studied in urethane-anesthetized female rats. The deposition of morphine and dopamine suppressed, while prolactin was found to enhance, the rate of spontaneous firing of more than half of the neurons recorded. It is suggested that the present findings may be of significance in the understanding of the interaction of the opioids, dopamine, and prolactin in the regulation of prolactin secretion.
Alcohol and inhibitory receptors: Unexpected specificity from a nonspecific drug

It is remarkable that a simple two-carbon molecule like ethyl alcohol produces the many neurological, physiological, and societal effects that result from alcohol (ethanol) use and misuse. It is the least potent of all drugs, requiring concentrations of 10-20 mM to produce intoxication in humans and 100-200 mM to produce anesthesia in experimental animals (1, 2). Because of the limited structural information that can be obtained from such a simple molecule and the high concentrations required, a nonspecific or nonreceptor-mediated mechanism of action was considered likely, and, as a result, early studies focused on the actions of alcohol on physical properties of membrane lipids. More recently, the search for sites of action shifted from lipids to proteins, but the identification of brain proteins that are clearly affected by ethanol at concentrations of 10-20 mM has proven remarkably elusive. For reference, a moderately intoxicating blood alcohol level of 0.08% (80 mg/dl) is equivalent to an ethanol concentration of 17 mM. In 1986 an important first step toward defining targets of alcohol action was taken when three groups demonstrated that intoxicating concentrations of ethanol enhance the function of γ-aminobutyric acid type A (GABAA) receptors, the major inhibitory neurotransmitter receptors in the brain (3-5). One of these studies also showed that this action was missing in a line of mice (short-sleep mice) exhibiting genetic resistance to alcohol actions, suggesting the existence of alcohol-sensitive and alcohol-resistant subtypes of GABAA receptors (3). Despite the numerous electrophysiological studies stimulated by these studies, there is no clear understanding of what makes a GABAA receptor sensitive to low millimolar concentrations of ethanol and indeed many studies find either no effect of ethanol or effects only at concentrations of ≈100 mM or more (6).
An imroved image demodulation algorithm based on Teager-Kaiser operator

In this paper a new wideband image demodulation algorithm based on the Teager-Kaiser operator is proposed. A Gabor filter bank is first used to decompose the wideband image into multiple narrow band components. Directly applied on these components, the demodulation yields many artifacts on both the amplitude and the frequency modulation counterparts. To reduce these artifacts, a low-pass filter in the demodulation process is introduced. An approximation of the Teager-Kaiser filtered image energy is proposed. A proposition related to that fact, along with the associated proof are provided. As illustrated by various examples, our demodulation approach is more robust to noise, and drastically improves the visual quality of the demodulation results. A direct consequence post-filtering or/and post-processing are not necessary.
Varactor-tunable uniplanar ring resonators

Slotline and CPW ring resonators are introduced and integrated with varactor diodes to create electronically tunable uniplanar ring resonators. Varactors electronically tune the second resonant mode of the slotline ring over a 23% bandwidth from 3.03 to 3.83 GHz with a 4.5+or-1.5 dB variation in insertion loss. Similarly, a CPW ring resonator was tuned over a 22% bandwidth from 2.88 to 3.59 GHz. Both resonators offer the ground plane and center conductor on the same side of the substrate to allow easy series or shunt insertion of solid-state devices. DC biasing is naturally integrated in the slotline structure and straightforward in CPW. Monolithic implementation of these resonators would not require via holes to ground solid-state devices which should reduce processing complexity and increase production yields. >
Ammonia sensing characteristics of quartz resonator coated with ZnO nanowires sensitive layer

In this paper, we present our recent study on the fabrication and characterization of ammonia gas sensors based on quartz thickness shear mode (TSM) resonators employing ZnO nanowires as the sensitive coating layer. c-axis vertically aligned ZnO nanowire arrays were synthesized on the quartz resonator through a simple hydrothermal synthesis route. The ZnO nanowires were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The sensing characteristics, including sensitivity, stability, reproducibility, and response time of the acoustic wave gas sensors have been studied under different concentration levels of ammonia at room temperature. It is demonstrated that the use of the ZnO nanowire arrays on quartz TSM acoustic wave resonator can greatly enhance the sensitivity and sensor response speed due to the fast surface/interface reaction and large surface/volume ratio of the nanowire arrays.
Renal Vulnerability to Drug Toxicity

Drug-induced kidney disease occurs primarily in patients with underlying risk factors. A number of factors enhance the vulnerability of the kidney to the nephrotoxic effects of drugs and toxins. They are broadly categorized as patient-specific, kidney-related, and drug-related factors. One, two, or all three of the factor categories can act to promote various forms of renal injury. Importantly, all compartments of the kidney can be affected and result in one or more classic clinical renal syndromes. These include acute kidney injury, various tubulopathies, proteinuric renal disease, and chronic kidney disease. Recognizing risk factors that increase renal vulnerability to drug-induced kidney disease is the first step in reducing the renal complications of drugs and toxins.
An Analysis of Globalization Forces in the Wine Industry

Abstract This paper examines the driving forces and key success factors related to the increasing globalization of the wine industry. It further analyzes the current competitive advantage positions of four Old and five New World wine producing countries. The group with the strongest sources of competitive advantage position includes the United States, Australia, and Chile. The group of countries with moderate competitive advantages includes Italy, Spain, Argentina and South Africa, and the countries with the weakest competitive advantages in the global wine industry are two traditional strongholds of wine production from the Old World: France and Germany. This competitive advantage scenario should be a wake-up call to many countries. The study offers three specific recommendations for wineries of all sizes in all nations. They are: (i) increased emphasis on market orientation, (ii) increased export assistance, (iii) managing trade barriers effectively.
A Qualitative Event-Based Approach to Continuous Systems Diagnosis

Fault diagnosis is crucial for ensuring the safe operation of complex engineering systems. Although discrete-event diagnosis methods are used extensively, they do not easily address parametric fault isolation in systems with complex continuous dynamics. This paper presents a novel event-based approach for diagnosis of abrupt parametric faults in continuous systems, based on a qualitative abstraction of measurement deviations from the nominal behavior. From a continuous model of the system, we systematically derive dynamic fault signatures expressed as event-based fault models, which are used, in turn, for designing an event-based diagnoser of the system and determining system diagnosability. The proposed approach is applied to a subset of the Advanced Diagnostics and Prognostics Testbed, which is representative of a spacecraft's electrical power system. We present experimental results from the actual testbed, as well as detailed simulation experiments that examine the performance of our diagnosis algorithms under different fault magnitudes and noise levels.
Charged black holes with scalar hair

We describe a family of static black-hole solutions arising in a theory with Einstein gravity coupled to electromagnetism and an axionlike scalar field. These solutions carry both electric and magnetic charge. In addition, the scalar field is spatially varying outside the horizon. Since this nontrivial scalar field is not required by any conservation law, these solutions shed further light on the black-hole no-hair conjecture.
Chemical and particle-size evidence for addition of fine dust to soils of the midwestern United States

Significant long-term atmospheric dust additions to soils are well documented in many parts of the world, but not in the midwestern United States. We investigated elemental mass fluxes associated with soil development in late Wisconsinan loess in Illinois and Minnesota, using Zr as a stable index element. Positive mass fluxes of Al, Fe, and Ti can most plausibly be explained by additions to these soils of fine far-traveled dust, with higher Al/Zr, Fe/Zr, and Ti/Zr ratios than the coarser locally derived loess. High-resolution particle-size analyses support this explanation. The proposed dust influx will complicate efforts to quantify weathering processes in these soils. Far-traveled dust influx could have occurred simultaneously with the final phase of local loess deposition, and/or later, in the Holocene. Depending on the timing of dust influx, many other soils of the region may have been affected by it.
Nursing home admission of female Alzheimer’s patients: family care aspects

This study examined patterns of nursing home admission for males and females with Alzheimer’s disease. It also examined reasons why women may be less likely to remain in home and family-based care. A 2-year, four-wave follow-up study was conducted among 573 patients and their family caregivers. Results from logistic regression analyses showed that females and males were institutionalized for different reasons. Men were institutionalized primarily for medical and caregiving need factors. Women showed less physical and less cognitive impairment, and their model of placement showed more importance of family caregiving patterns.
β1-Integrins Regulate the Formation and Adhesion of Ovarian Carcinoma Multicellular Spheroids

Ovarian carcinoma multicellular spheroids are an in vitro model of micrometastasis whose adhesive abilities have not been elucidated. In this study, we identified adhesion molecules that mediate the formation of ovarian carcinoma spheroids and their subsequent adhesion to extracellular matrix proteins. The NIH:OVCAR5, but not the SKOV3, ovarian carcinoma cell line formed spheroids similar to multicellular aggregates isolated from patient ascitic fluid. NIH:OVCAR5 spheroid formation was augmented by a β1-integrin-stimulating monoclonal antibody or exogenous fibronectin, but was inhibited by blocking monoclonal antibodies against the α5- or β1-integrin subunits. By immunohistochemical staining, α2-, α3-, α5-, α6-, and β1-integrin subunits, CD44, and fibronectin were detected in NIH:OVCAR5 spheroids. NIH:OVCAR5 spheroids adhered to fibronectin, laminin, and type IV collagen, and this adhesion was partially inhibited by blocking antibodies against the α5-, α6-, and α2-integrin subunits, respectively. A blocking monoclonal antibody against the β1-integrin subunit completely inhibited adhesion of the spheroids to all three proteins. These results suggest that interactions between the α5β1-integrin and fibronectin mediate the formation of ovarian carcinoma spheroids and that their adhesion to extracellular matrix proteins at sites of secondary tumor growth may be mediated by a complex interaction between multiple integrins and their ligands.
Kinetic theory for a short-wavelength lasing plasma

A kinetic analysis is made of a reacting plasma dominated by three-body recombination and ionization, together with collisional and radiative excitation and de-excitation of atomic states. The plasma includes excited atoms, ions, electrons and photons. The kinetic theory yields rate equations for these species, together with explicit expressions for relevant rate coefficients. In the limit of spatial homogeneity and assuming atom and electron densities are close to equilibrium, an explicit form is obtained for the radiation absorption coefficient per unit length. A criterion is then constructed for population inversion. Application to a helium-like active medium (e.g. Al +11 ) and hydrogen-like passive medium (e.g. A1 +12 ), at electron temperature of 300 eV, reveals that population inversion ensues at electron densities in excess of 10 20 cm −3 . Algebraic solution of atomic state rate equations demonstrates that the absorption coefficient grows insensitive to photon-atom interactions with increasing electron density.
Does Treatment Influence Mortality in Depressives?: A Follow-up of 1076 Patients with Major Affective Disorders

AbstractThis article reports mortality risk among 1076 Iowans with major affective disorders (705 primary unipolar, 219 secondary unipolar, and 152 bipolar depressives) compared to that of the general population. Patients were divided into four treatment groups depending on primary mode of therapy during the index admission; the groups included electroconvulsive therapy (ECT), adequate antidepressants, inadequate antidepressants, and neither treatment. All patients in the sample had an increased risk for an early death. A high risk for suicide was found for patients within each individual treatment group during the follow-up, especially the first 2 years when 69.4% (n = 25) of total suicides occurred. There were no significant differences in the risk for suicides, or deaths from all causes combined, among patients in the four treatment groups. Furthermore, mortality did not differ between patients having a lifetime history of ECT and patients never having had ECT. We conclude from a short-term follow-up o...
Dust in Dense Clouds

Recent observational and theoretical studies of dust in dense clouds are reviewed with an emphasis on the growth of dust grains through accretion and coagulation. IR reflection nebulae around protostellar objects are useful probes of grain sizes in dense clouds. For example, detailed studies of the IR reflection nebula surrounding OMC 2-IRS 1 show that the (scattering) grains are much larger (≈ 5000 A) than in the diffuse interstellar medium. Likewise, the presence of a weak shoulder at 2.95 µm on the 3.08 µm feature in BN indicates the importance of scattering by icy grains and implies a very similar increase in the grain size.
Commentary on: Analysis of Cosmetic Topics on the Plastic Surgery In-Service Training Exam.

Dr. Chang and his team should be congratulated for a thoughtful investigation.1 They have compiled a statistical analysis comparing the cosmetic topic of each question on the In-Service Examination to the national procedural data of cosmetic operations performed. The structure of this paper is a retrospective review of published exams over the last six years—the anticipated training timeline of a new resident beginning out of medical school. The topic-specific question distribution is then compared against self-reported procedural data obtained via a survey of practicing surgeons. The assumption of this paper is that the topics covered in the cosmetic questions of the In-Service Examination should mirror national procedural volume and that, if this correlation were followed, the examination would be a better test for resident teaching. The subsequent statistical analysis demonstrates the In-Service Exam topic frequency does not mimic procedural volume. We disagree with this basic assumption. We do not believe that the number of questions on a specific topic should mimic the number of these procedures performed in practice. For example, we have purposefully written questions on the subject of anaplastic large cell lymphoma (ALCL) in both the cosmetic section and the comprehensive section of the exam. Every surgeon should suspect ALCL when a patient presents with …
Scattering and diffusion of seismic waves

Elastic radiative transfer equations have recently been derived to describe the evolution of seismic energy in the crust of the earth (Ryzhik et al. , 1996). These equations are derived from a rigorous statistical treatment of the elastic-wave equation and include both shear polarizations and mode conversion between the P and S modes. Calculations of attenuations ratios and diffusion constants based upon these theories are made and compared with values used in the literature. Equivalent elastic radiative transfer equations have also been previously derived for ultrasonic materials characterization purposes using a different method. Observations made from numerical solutions of these ultrasonic radiative transfer equations are discussed with application to seismology. Both the steady-state and time-dependent solutions have been examined including effects from boundaries, depolarization of S waves approach to isotropy of energy, and validity of the diffusion approximation. Similar results are expected for seismology.

IBM POWER7 multicore server processor

The IBM POWER® processor is the dominant reduced instruction set computing microprocessor in the world today, with a rich history of implementation and innovation over the last 20 years. In this paper, we describe the key features of the POWER7® processor chip. On the chip is an eight-core processor, with each core capable of four-way simultaneous multithreaded operation. Fabricated in IBM's 45-nm silicon-on-insulator (SOI) technology with 11 levels of metal, the chip contains more than one billion transistors. The processor core and caches are significantly enhanced to boost the performance of both single-threaded response-time-oriented, as well as multithreaded, throughput-oriented applications. The memory subsystem contains three levels of on-chip cache, with SOI embedded dynamic random access memory (DRAM) devices used as the last level of cache. A new memory interface using buffered double-data-rate-three DRAM and improvements in reliability, availability, and serviceability are discussed
Abstract 3036: Interaction of proliferation cell nuclear antigen (PCNA) with c-Abl in cell proliferation and response to DNA damages in breast cancer

Proceedings: AACR 103rd Annual Meeting 2012‐‐ Mar 31‐Apr 4, 2012; Chicago, IL Cell proliferation in primary and metastatic tumors is a fundamental characteristic of advanced breast cancer. Further understanding of the mechanism underlying enhanced cell growth will be important in identifying novel prognostic markers and therapeutic targets. Here we demonstrated that tyrosine phosphorylation of the proliferating cell nuclear antigen (PCNA) is a critical event in growth regulation of breast cancer cells. We found that phosphorylation of PCNA at tyrosine 211 (Y211) enhanced its association with the non-receptor tyrosine kinase c-Abl. We further demonstrated that c-Abl facilitates chromatin association of PCNA and is required for nuclear foci formation of PCNA in cells stressed by DNA damage as well as in unperturbed cells. Targeting Y211 phosphorylation of PCNA with a cell-permeable peptide inhibited the phosphorylation and reduced the PCNA-Abl interaction. These results show that PCNA signal transduction has an important impact on the growth regulation of breast cancer cells. Citation Format: {Authors}. {Abstract title} [abstract].

Chapter 19 – Handling and Storage of Cells and Sera: Practical Considerations

This chapter discusses practical considerations for handling and storage of cells and sera. The procedures and protocols for storage should be validated and standardized and tailored to the specific nature of the investigations. Temperature may affect sample stability during sample collection and processing as well as during storage. The sample is ideally separated into different components and stored at the appropriate temperature; for example, DNA may be stored at 4°C for several weeks, at –20°C for several months, and at –80°C for several years. Isolated RNA must be stored at –80°C. Live cells are stable at room temperature for up to 48 h, but must be cultured or cryopreserved in liquid nitrogen at –150°C to remain alive. Serum and plasma require temperatures of –80°C to preserve a large number of soluble components. Citrate-stabilized blood may offer better quality of RNA and DNA and produces a higher yield of lymphocytes for culture. Heparin-stabilized blood, on the other hand, affects T cell proliferation. Collection of whole blood in any type of anticoagulant-containing tubes may induce cytokine production in vitro. The chapter briefly describes early identification of potential biomarkers and conditions for storage, as well as their confidentiality and ownership issues.
Radialenes are minimally conjugated cyclic π-systems

ABSTRACTConjugation energy (CE) in benzene is larger than its aromatic stabilisation energy (ASE). A far-reaching conclusion offered by this work is that per π-electron, CE is energetically larger than aromaticity. If a diene has a doubly degenerate HOMO, then its Diels–Alder reaction will be kinetically faster than a similar diene with a nondegenerate HOMO. The topological conjugation energy (TCE) for the radialene, monocyclic, dendralene, and linear polyene series has quite different trends. Radialenes are minimally conjugated cyclic systems with the TCE/No. π-bond = 0.432 β; the members of the dendralene series approach this same value from smaller values with increasing size. With increasing size, the members of the monocyclic and linear polyene series have, respectively, decreasing and increasing TCE/No. π-bond values approaching 0.547 β. Topological resonance energy (TRE) for radialenes, dendralenes, and linear polyenes all have TRE = 0, and the TRE/π-electron for monocyclic polyenes has alternating...
Open and Arthroscopic with Mini-Open Surgical Hip Approaches for Treatment of Pigmented Villonodular Synovitis and Concomitant Hip Pathology.

Background. Pigmented villonodular synovitis (PVNS) is a rare benign tumor affecting large joints and prompts excision to prevent local destruction of the joint. The purpose of this case report is to describe two differing surgical approaches for management of PVNS of the hip in patients requiring concomitant treatment for additional hip pathology. Methods. This report discusses the presentation, clinical and radiographic findings, and operative management of two contrasting cases of PVNS of the hip. Case describes a 31-year-old female with localized PVNS in addition to a labral tear treated with arthroscopic labral repair followed by tumor excision via a mini-open incision. Case describes a 29-year-old male with more diffuse PVNS in addition to a cam deformity managed with open surgical dislocation of the hip, tumor excision, and restoration of the femoral head/neck junction. Results. This report demonstrates two cases of successful excision of PVNS of the hip in addition to addressing concomitant hip pathology in both cases. Conclusions. Open surgical dislocation of the hip or arthroscopic surgery with a mini-open incision may be used in appropriately selected patients to successfully excise PVNS lesions in addition to addressing concomitant hip pathology.

Strength activity and microstructure of blended ultra-fine coal bottom ash-cement mortar

Abstract Replacing Portland cement with reutilized coal combustion products can have substantial benefits to the environment as well as infrastructure. In this study, a sub-bituminous coal bottom ash is re-utilized as a cement replacement. The bottom ash was pulverized using a high energy vibratory ball mill at two different milling times to achieve a particle fineness approximately two and three-times finer, respectively, than type I cement. The workability and final setting time were found to increase by 21% and 14%, respectively, and the highest strength activity was observed to be 120% at 90 days. After normalization for particle fineness, age, and binder replacement using a general linear regression model, the data suggested the bottom ash blended cement mortar had 6.8% less strength activity than a comparative fly ash blended cement mortar. Blended bottom ash-cement paste samples were observed to have densely packed CSH product composed of relatively lower Ca/Si ratio (1.37) compared to that of fly ash blended cement paste (1.43) and the control (2.27). The CH content was also observed to be significantly lower in the bottom ash blended cement paste (19.1%) when compared against the control (27.2%) and fly ash blended paste (23.3%). Within the range of experimental conditions considered here, the results suggest that a coal bottom ash can be pulverized with a high energy ball mill to produce a re-utilizable pozzolan that, depending on the powder fineness, can significantly increase the strength activity, improve the microstructure of cement mortar, and increase the cement replacement tolerances without significant reduction to compressive strength activity.
Education as a Praxis of Soul Consciousness: Insinuations of Liberation Pedagogies in Higher Education and Human Rights Discourse

The concept and practice of “education” are an Occidental (European) social/political construction created at the service of the perpetuation and expansion of the West. Consequently, all of its considerations: discourses about rights, laws, protections, about sovereignty, good, justice, or democracy have been developed (or not) only to the extent that they promoted Occidentalism and the Western modernity project. This theoretical inquiry is an attempt to engage in a “critical caution” for an argument of higher education as a “human right.” In addition, this inquiry attempts to understand power relations in education to imagine learning as a political activity as part of the architecture of human liberation and insinuate this value in the discourse of human rights and higher education.
Modelling yawed wind turbine wakes: a lifting line approach

Yawing wind turbines has emerged as an appealing method for wake deflection. However, the associated flow properties, including the magnitude of the transverse velocity associated with yawed turbines, are not fully understood. In this paper, we view a yawed turbine as a lifting surface with an elliptic distribution of transverse lift. Prandtl’s lifting line theory provides predictions for the transverse velocity and magnitude of the shed counter-rotating vortex pair known to form downstream of the yawed turbine. The streamwise velocity deficit behind the turbine can then be obtained using classical momentum theory. This new model for the near-disk inviscid region of the flow is compared to numerical simulations and found to yield more accurate predictions of the initial transverse velocity and wake skewness angle than existing models. We use these predictions as initial conditions in a wake model of the downstream evolution of the turbulent wake flow and compare predicted wake deflection with measurements from wind tunnel experiments.
Thermal-aware joint CPU and memory scheduling for hard real-time tasks on multicore 3D platforms

Designing 3D systems with on-chip DRAM is a promising solution to improve memory bandwidth and reduce memory access latency. However, 3D chips exacerbate the chip thermal problem due to their longer heat dissipation path, as well as the tight thermal coupling between logic and memory layers. In this paper, we are interested in studying thermal aware resource management strategies for both CPUs and memory systems when realizing hard real-time systems on 3D platforms under given peak temperature constraints. Given the dramatically increased power density not only from CPUs but also from memory systems as well, we believe that a joint CPU and memory system resource management is highly desired for 3D platforms to effectively deal with the heat dissipation confined in a small package. In addition, different from many existing thermal management strategies, which are reactive and best-effort in nature, we are more interested in ones that can ensure the strong guarantee for real-time applications. To this end, we introduce a novel approach that incorporates the periodic resource model to guarantee timing constraints for hard real-time systems under thermal constraints. In the meantime, by periodically (deterministically) throttling the accesses of CPUs and memory resources, our approach can effectively guarantee the thermal constraints imposed on both CPUs and memory systems. We use simulation results to demonstrate the effectiveness of our proposed approach in guaranteeing both the timing and temperature constraints for hard real-time tasks on 3D platforms.

Transparency Laws and Compliance: Implications for Board Members

Whether via email or text message, public entities are using technology-based platforms to communicate with each other and their constituents. Courts and state legislatures are formally recognizing that such communications are subject to disclosure under transparency laws. Many professional licensing boards, such as state boards of nursing, have part-time members who correspond with staff and other members using private email addresses and text messages from private phones. This article explores transparency laws and outlines what board members should be cognizant of as those laws pertain to electronic communications.

Stelae, Elephants, and Irony: The Battle of Raphia and Its Import as Historical Context for 3 Maccabees

The opening verses of 3 Maccabees set the story in the aftermath of the Battle of Raphia (217 BCE ); the significance of this historical setting has been overlooked. The Battle of Raphia is intimately related to the narrative at large in at least three ways. First, 3 Maccabees advocates for a counter-tradition to a stele tradition that arises out of Ptolemy’s victory at Raphia. Second, the story reworks the famous incident of Ptolemy’s elephant retreat at Raphia into a tale of praise for the God of the Jews. And finally, the book is invested with the irony already present in the historical realities of Ptolemy’s short-lived victory.

Abstract CN05-02: Novel mechanisms of PARP inhibitor resistance

Large-scale genomic studies have demonstrated that approximately 50% of high-grade serous ovarian cancers (HGSOCs) harbor genetic and epigenetic alterations in homologous recombination repair (HRR) pathway genes. The most commonly altered HRR genes are BRCA1 and BRCA2, followed by other Fanconi anemia genes including FANCN/PALB2, FANCO/RAD51, FANCJ/BRIP, and FANCA. Loss of HRR causes genomic instability, hyperdependence on alternative DNA repair mechanisms, and enhanced sensitivity to platinum analogues, topoisomerase inhibitors, and PARP inhibitors (PARPi). The synthetic lethal interaction with PARPi is being exploited therapeutically in diverse clinical contexts and most notably in ovarian cancer where multiple PARPi have been FDA approved. PARP inhibitor resistance has already emerged as a vexing clinical problem for the treatment of BRCA1/2-deficient tumors. The most prevalent mechanism of PARPi resistance is secondary events that cancel the original HRR alteration and restore HRR proficiency. However, PARPi resistance may still develop without restoration of HRR proficiency via disruption of multiple proteins, such as PTIP or CHD4, that leads to replication fork (RF) stabilization. Importantly, this latter mechanism–namely, the restoration of RF stability–appears to be a highly prevalent mechanism of PARPi resistance in vitro and in vivo, particularly in tumor cells with an underlying BRCA2 deficiency. Due to their underlying deficiency in BRCA2 and inability to generate RAD51 nucleofilaments, these tumor cells are unable to restore HRR mechanisms. Instead, these cells acquire PARPi resistance by limiting the nucleolytic degradation of their stalled replication forks. We have recently made the surprising observation that BRCA2-deficient tumors can become resistant to PARPi by downregulating the expression of the polycomb repressive complex PRC2, a methyltransferase complex containing EZH2, SUZ12, EED, and RbAp48. Importantly, downregulation of PRC2 results in the reduced recruitment of the nuclease MUS81 to the RF, thereby providing a novel mechanism of RF protection and PARPi resistance. A molecular understanding of PARPi resistance mechanisms may allow the generation of a new class of drugs or a repurposing of existing drugs, which may reverse this resistance and extend the use of PARPi to more tumor types.

Scalable Virtualization and Offloading-Based Software-Defined Architecture for Heterogeneous Statistical QoS Provisioning Over 5G Multimedia Mobile Wireless Networks

As a crucial step moving towards the next generation of super-fast wireless networks, recently the fifth-generation (5G) mobile wireless networks have received a plethora of research attention and efforts from both the academia and industry. The 5G mobile wireless networks are expected to provision distinct delay-bounded quality of service (QoS) guarantees for a wide range of multimedia services, applications, and users with extremely diverse requirements. However, how to efficiently support multimedia services over 5G wireless networks has imposed many new challenging issues not encountered before in the fourth-generation wireless networks. To overcome these new challenges, we propose a novel network-function virtualization and mobile-traffic offloading based software-defined network (SDN) architecture for heterogeneous statistical QoS provisioning over 5G multimedia mobile wireless networks. Specifically, we develop the novel SDN architecture to scalably virtualize wireless resources and physical infrastructures, based on user’s locations and requests, into three types of virtual wireless networks: virtual networks without offloading, virtual networks with WiFi offloading, and virtual networks with device-to-device offloading. We derive the optimal transmit power allocation schemes to maximize the aggregate effective capacity, overall spectrum efficiency, and other related performances for these three types of virtual wireless networks. We also derive the scalability improvements of our proposed three integrated virtual networks. Finally, we validate and evaluate our developed schemes through numerical analyses, showing significant performance improvements as compared with other existing schemes.
Poisson Equation Solution and Its Gradient Vector Field to Geometric Features Detection

In this paper we solve the Poisson partial differential equation (PDE) with a free right side, which is a function of the image and its gradient. We call such a PDE Poisson Image (PI) equation. Further, we define the function \(\phi ={u+\left\| \nabla u\right\| }^2\), where u is the PI’s solution. Then, we generate the Poisson gradient vector fields (PGVFs) \(\nabla u\) and \(\nabla \phi \) and study the patterns of their trajectories in the vicinity of the singular points (SPs). Next, we use the critical points (CPs) of u and \(\phi \), the SPs of \(\nabla u\) and \( \nabla \phi \), and their relations, to determine the image objects’ concavities and convexities, and use them for automatic objects partitioning. We validated the theoretical concepts with experiments on above 80 synthetic and real-life images, and show some of them in the paper. At the end we compare the new method with contemporary methods in the field and list its contributions, advantages and bottlenecks.
Tree Species Use and Seasonal Response to Food Availability of Black-Capped Vireo

The ability of songbirds to survive and reproduce depends on many factors, one of which is the ability to acquire enough food. We quantified foraging behavior, nestinghabitat vegetation composition, and available arthropod prey of the Vireo atricapilla (Black-capped Vireo) in Texas during 2010 and 2011. We used observational surveys of foraging behavior and vegetation time-use to quantify the Black-capped Vireos' foraging behavior and vegetative use versus availability (i.e., mean proportion of use vs. vegetative species availability). We collected descriptive data on the Black-capped Vireos' foraging use of available vegetative species and compared among vegetative species, year, and within-season sampling periods. In 2010 and 2011, we identified and mapped 49 and 63 breeding territories and repeatedly surveyed 30 and 58 territories for foraging activity, respectively. Data analysis focused on the foraging use of the 3 most commonly used and available tree species: Juniperus ashei (Ashe Juniper), Quercus sinuata (Shin Oak), and Q. fusiformis (Live Oak). Ashe Juniper, Shin Oak, and Live Oak together made up 78.8% and 83.6% of total proportion of substrate for foraging efforts in 2010 and 2011, respectively. Ashe Juniper had the highest proportion (~28–50%) of foraging effort in 2010, 2011, and all but 1 sampling period for both years. We also repeatedly collected branch clippings from within a random subset of surveyed Black-capped Vireo territories to identify potentially available arthropod foods. We evaluated by order richness, total abundance, and dry biomass to make comparisons among vegetative species, year, and within-season sampling periods. We found significant differences in the biomass of arthropod orders Acari and Thysanoptera in 2010 and between orders Acari and Hymenoptera in 2011 among the 3 focal vegetative species. Examination of additional descriptive data suggests seasonal changes in potentially available arthropod foods. Our research underscores the importance of vegetation composition to Black-capped Vireos that may help habitat managers select for potential vegetative species distributions to optimize food resources throughout the breeding season for this species.
