Full textAbstract:
After establishment of design requirements and creation of an initial shape, the design process of free form shapes should include interrogation and fairing until a desired shape, with appropriate geometric and performance characteristics, is achieved. Afterwards, the quality of the manufactured product can be determined by comparing measured data with the design model. To permit automated design and manufacturing, mathematical methods and algorithms for the creation, interrogation, fairing, and inspection of curves and surfaces have been developed and integrated into a computer system called Praxiteles. The general layout of Praxiteles, along with a description of design capabilities, is presented. This description covers the areas of input, output, approximation and conversion for data exchange, a summary of some shape creation methods, and a description of some advanced interactive interrogation, fairing, and inspection methods for NURBS curves and surfaces. Examples illustrate some of the features of the system, as applied in the design and inspection of marine propellers. Recommendations for future development of the system are also presented.

Full textAbstract:
One of the most consistent findings in the domain of criminal justice is that female and male offenders are perceived differently, often resulting in milder sentencing of women compared to men. Although previous studies have sought to identify factors that shape public reactions to terrorism and support for harsh interrogation techniques in its aftermath, empirical studies on differential reactions to female (vs. male) terrorist violence remain scarce. Here, it is argued that the often-violent evolutionary history of our species has shaped the way in which we perceive and react to female (vs. male) terrorist violence. Based on the framework of coalitional psychology—and specifically, the male warrior hypothesis—the assumption is tested that terror-suspect sex, in interaction with other threat cues such as in- or out-group membership and size of coalition, affects support for interrogational torture. This prediction was tested by conducting a survey experiment on a nationally representative sample of 2,126 U.S. adults. Results demonstrated that terror-suspect sex significantly shapes reactions to and perceptions of terrorist violence. Further, nuanced responses based on respondent sex revealed that these associations were exclusively driven by male participants. Gender attitudes and mere punitiveness did not account for the findings, suggesting that male coalitional psychology is deeply ingrained and readily activated by cues implying intergroup conflict.

The paper presents an approach to detect and control the focus of attention of the suspect using his/her eye gaze and head movement direction to build up an automatic interrogation system- specially to detect lies. To this point, we classified interrogation conversation into different criteria and identified the fatal ones. At first, we conducted psychological experiments on the sampled population to detect the different parameters connected with various symptoms when the suspect tells lies and build our knowledgebase with the results. This knowledgebase helps the system to make strategic decisions and to optimize accuracy. A monitoring camera captures continuous interrogation and feeds the frames to our proposed system. 3D head tracker is used to track the head from image and Active Shape Model (ASM) is utilized to localize face points. Vector Field of Image Gradient (VFIG) is calculated to track the eyeball and its rotation within the eye area. Random eye and head movement, change of eyebrow at the critical level of questionnaire provide us the possibility of detecting lies. Finally, experiments are conducted in a controlled environment to validate our psychological findings.

Full textAbstract:
Shielded special nuclear material (SNM), especially highly enriched uranium, is exceptionally difficult to detect without the use of active interrogation (AI). We are investigating the potential use of low-dose active interrogation to realize simultaneous high-contrast imaging and photofission of SNM using energetic gamma-rays produced by low-energy nuclear reactions, such as [Formula: see text]B(d,n[Formula: see text]C and [Formula: see text]C(p,p[Formula: see text]C. Neutrons produced via fission are one reliable signature of the presence of SNM and are usually identified by their unique timing characteristics, such as the delayed neutron die-away. Fast neutron spectroscopy may provide additional useful discriminating characteristics for SNM detection. Spectroscopic measurements can be conducted by recoil-based or thermalization and capture-gated detectors; the latter may offer unique advantages since they facilitate low-statistics and event-by-event neutron energy measurements without spectrum unfolding. We describe the results of the development and characterization of a new type of capture-gated spectroscopic neutron detector based on a composite of scintillating polyvinyltoluene and lithium-doped scintillating glass in the form of millimeter-thick rods. The detector achieves >108 neutron–gamma discrimination resulting from its geometric properties and material selection. The design facilitates simultaneous pulse shape and pulse height discrimination, despite the fact that no materials intrinsically capable of pulse shape discrimination have been used to construct the detector. Accurate single-event measurements of neutron energy may be possible even when the energy is relatively low, such as with delayed fission neutrons. Simulation and preliminary measurements using the new composite detector are described, including those conducted using radioisotope sources and the low-dose active interrogation system based on low-energy nuclear reactions.

Full textAbstract:
This paper presents accurate algorithms for the extraction of gross geometrical features of marine propeller blades represented in terms of B-spline surfaces. These features have important hydrodynamic function and include specifically the camber surface, the section thickness function, pitch, rake, skew, chord length, maximum thickness, maximum camber of the section and leading edge. The approximation of the camber surface, on which most of the remaining features are based, is an intricate problem relying on an extension of the concept of a Brooks ribbon and requiring the solution of a complex system of nonlinear differential equations, developed for the problem at hand, and a sophisticated error evaluation scheme. The above features provide an alternate abstract representation of propeller blades useful in geometric design through lofting and fairing processes, in idealization for hydrodynamic and structural dynamic analyses and in verification of the quality of a manufactured blade. Furthermore, the derivation of these design features provides an alternate shape interrogation method for propeller blades, which is more intuitive for propeller designers in comparison with existing surface interrogation techniques.

Full textAbstract:
Interferometric fiber-optic sensors are often organized in the form of large-scale arrays by lending the technique of time division multiplexing (TDM) to reduce the system cost. Discriminating the time windows for different sensor units is the prerequisite to successfully demodulate the sensing message, but it traditionally calls for a very time-consuming manual calibration process. To combat this problem, a novel automatic time window locating method is proposed in this paper. It introduces the concept of shape function and carries out the cross-correlation operation between the shape function and the sensor signal. The shape function is defined as the function whose curve profile reflects the main data characteristics of the sensor signal. The time window information is then extracted from the correlation result. This whole process is carried out automatically by the interrogation controller of the sensor system without any manual intervene. Experiments are conducted to validate this method. The proposed method can greatly reduce the complexity of locating time windows in large-scale TDM sensor arrays, and make the practical use of the TDM scheme much more convenient.

"Raman interrogation of the ferroelectric phase transition in polar metal LiOsO3." Proceedings of the National Academy of Sciences 116, no. 41 (September 23, 2019): 20322–27. http://dx.doi.org/10.1073/pnas.1908956116.
Full textAbstract:
Ferroelectric (FE) distortions in a metallic material were believed to be experimentally inaccessible because itinerant electrons would screen the long-range Coulomb interactions that favor a polar structure. It has been suggested by Anderson and Blount [P. W. Anderson, E. I. Blount, Phys. Rev. Lett. 14, 217−219 (1965)] that a transition from paraelectric phase to FE phase is possible for a metal if, in the paraelectric phase, the electrons at the Fermi level are decoupled from the soft transverse optical phonons, which lead to ferroelectricity. Here, using Raman spectroscopy combined with magnetotransport measurements on a recently discovered FE metal LiOsO3, we demonstrate active interplay of itinerant electrons and the FE order: Itinerant electrons cause strong renormalization of the FE order parameter, leading to a more gradual transition in LiOsO3 than typical insulating FEs. In return, the FE order enhances the anisotropy of charge transport between parallel and perpendicular to the polarization direction. The temperature-dependent evolution of Raman active in-plane 3Eg phonon, which strongly couples to the polar-active out-of-the-plane A2u phonon mode in the high-temperature paraelectric state, exhibits a deviation in Raman shift from the expectation of the pseudospin−phonon model that is widely used to model many insulating FEs. The Curie−Weiss temperature (θ ≈ 97 K) obtained from the optical susceptibility is substantially lower than Ts, suggesting a strong suppression of FE fluctuations. Both line width and Fano line shape of 3Eg Raman mode exhibit a strong electron−phonon coupling in the high-temperature paraelectric phase, which disappears in the FE phase, challenging Anderson/Blount’s proposal for the formation of FE metals.

Full textAbstract:
The paper is constructed around the issues involved for the critical interrogation of the instrumental rationality generating political thoughtlessness in the following claim: “Humanity is in crisis—and there is no exit from that crisis other than solidarity of humans”. [Zygmunt Bauman] To even interrogate this as a crisis requires a depth-analysis of the hegemony of subject-formation, and this occurs in two markedly different ways. The first takes shape around a critical investigation of the neoliberalisation of subjectivity through Francis Fukuyama’s important text, The End of History and the Last Man. The second subjects the neoliberal post-political global subject to a competing antagonistic political construal in Samuel Huntington’s influential The Clash of Civilizations. The implication is of their importance to a genealogy of the range of contemporary political possibilities. The suggested repair takes the form of a particular gesture: a gesture towards subjecting the globally fractured subject takes shape within a theological configuration in terms of a Christic politics of neighbourliness.

Full textAbstract:
Early animal development is characterized by intense reorganization of the embryonic genome, including large-scale changes in chromatin structure and in the DNA and histone modifications that help shape this structure. Particularly profound shifts in the chromatin landscape are associated with the maternal-to-zygotic transition, when the zygotic genome is first transcribed and maternally loaded transcripts are degraded. The accessibility of the early zebrafish embryo facilitates the interrogation of chromatin during this critical window of development, making it an important model for early chromatin regulation. Here, we review our current understanding of chromatin dynamics during early zebrafish development, highlighting new advances as well as similarities and differences between early chromatin regulation in zebrafish and other species.

This paper presents techniques for managing solid models in relational database management systems. Our goal is to enable support for traditional database operations (sorting, distance metrics, range queries, nearest neighbors, etc) on large databases of solid models. We introduce an approach to compare models based on shape using information extracted from the model boundary representation into Model Signature Graphs. We show how the Model Signature Graphs can be used to compute topological distances among models and how to use these measures to create metric spaces for indexing and clustering of solid models. We believe this work will begin to bridge the solid modeling and database communities, enabling new paradigms for interrogation of CAD datasets based on the engineering content of solid models.

In aerospace applications the development of a reliable method of structural health monitoring (SHM) is one of the most important keys in maintaining the integrity and safety of structures, preventing catastrophic failure. The research program DEDALO aims at developing a real size UHTC-based prototype with a complex shape equipped with a SHM system for damage detection. A multidisciplinary approach has been adopted involving mechanical design, materials science, manufacturing processes and development of optical devices to detect strain and temperature on the as-produced UHTC articles. Former activities merged into the manufacturing of a prototype hot structure supplied with optical sensing nodes to perform a functional test at high temperature. This communication describes the preliminary findings of the project. A series of ZrB-SiC based compositions was studied adjusting type, concentration and granulometry of reinforcing phases and additives to further identify the optimal composition for the hot structure. The pressureless sintering technique was selected privileging a near-net-shape approach to reduce the manufacturing costs. A SHM system was developed using commercial high temperature Fiber optic Bragg Grating (FBG), for thermal monitoring, and custom silica-sapphire fiber optic strain sensor, based on Fabry-Pèrot configuration, allowing simultaneous and real time measurement of temperature and structural loads applied on the structure under investigation. A ceramic flexible structure was developed to ease sensor installation procedure on complex shape test articles. The fiber optic sensors interrogation system was developed based on a tunable laser source. Thermal and mechanical tests showed sensor robustness at high temperature and 0,6 µε as accuracy on strain measurement 0 togliere up to 800°C. Tile-shaped hot structures were manufactured, equipped with the prototype Structural Health Monitoring System (SHMS) and functionally tested at high temperature. The project will undergo a second iterative loop which foresees investigation on the final test article: a ZrB2-SiC based composite hollow tip.

Human rights organizations (HROs) frame advocacy campaigns in order to shape individuals’ values and mobilize them to act. While previous work has examined some commonly used HRO frames, we know little about how they work as most often utilized—in combination. In this experiment, participants were randomly assigned either to a control group or to treatment groups shown campaigns against sleep deprivation during interrogation featuring frames used alone or in combination. We find that effects of personal frames on action mobilization are not mitigated by the inclusion of other frames, and that human rights campaigns with multiple frames yield outcomes that are neither better nor worse than a single personal narrative of human suffering. HROs should be able to use multiple frames in combination as needed without concern.

Critical interrogation of social work texts reveals ideologies contributing to hegemonic ‘taken-for-granted’ knowledge that maintains oppressive power relations. In the South African context of ongoing inequality after the 1994 democratic transition, neo-liberal ideologies have structured and constrained social work knowledge and practice constitutive of social change. Similarly, conservative neo-liberal ideologies underpinning social work knowledge and discourse act performatively to shape practice and social realities. This article, based on a section of the author’s PhD study, examines one of the thematic ideological trends found in post-1994 social work texts on poverty and social development, which reflect neo-liberal, individualist ideologies of ‘blaming-the-poor’ and personal culpability for poverty. A selection of three texts is discussed, illustrating processes and modes of operation of these ideologies in the various approaches proposed.

We consider some current directions in the preparation, characterization, manipulation, and interrogation of nanomaterials, in conjunction with the modeling of the unique structuredynamicsfunction relations of nanostructures and their assemblies. The implications of quantum size and shape effects on the energetics, nuclearelectronic level structure, electric-optical response and dynamics, reveal new unique physical phenomena that qualitatively differ from those of the bulk matter and provide avenues for the control of the function of nanostructures. Current applications in the realm of nanoelectronics, nanooptoelectronics, and information nanoprocessing are addressed, and other directions highlighted. Chemical sciences make a central contribution to this novel and exciting scientifictechnological area.

Full textAbstract:
Drawing on the hierarchy of influences perspective as analytical lens, this article examines the macro-, meso- and micro-level dynamics that attend the B-Metro’s mediation of child abuse in Zimbabwe. In-depth interviews with B-Metro staff revealed that journalists’ identities, professional ideologies, political meddling, resourcing challenges and a gendered newsroom culture shape the news discourse. Additionally, strategic considerations about the credibility of the news report and the economics of news gathering have led to an overreliance on court sources. Consequently, the reportage is dominated by a legal narrative that eschews meaningful interrogation of the structural conditions that engender child abuse. Findings also reveal that journalists denounce patriarchal violence but espouse its normative ideologies. Ambivalence characterizes journalists’ convictions and actions as they are torn between commercial and public interest imperatives, compassion fatigue and the ethic of care.

Abstract A theory is developed for the effect of coherent population trapping (CPT) in ‘hot’ atoms under pulsed pumping in an optically dense medium with a buffer gas. The case is considered when the excited level is not degenerate. Based on an analysis of the shape of Ramsey resonances, we show that with increasing optical density of the medium, the dependence of the light shifts of the CPT resonance becomes more and more nontrivial. The dependence of the light shifts of the CPT resonance on the magnitude of the hyperfine splitting of the excited level, concentration of active atoms, temperature, and duration of the dark pause is constructed.

Full textAbstract:
In the food industry, composition, size, and shape of items are much less regular than in other commodities sectors. In addition, a wide variety of packaging, composed by different materials, is employed. As material, size and shape of items to which the tag should be attached strongly influence the minimum power requested for tag functioning, performance improvements can be achieved only selecting suitable radio frequency (RF) identifiers for the specific combination of food product and packaging. When dealing with logistics units, the dynamic reading of a vast number of tags could originate simultaneous broadcasting of signals (tag-to-tag collisions) that could affect reading rates and the overall reliability of the identification procedure. This paper reports the results of an analysis of the reading performance of ultra high frequency radio frequency identification systems for multiple static and dynamic electronic identification of food packed products in controlled conditions. Products were considered when arranged on a logistics pallet. The effects on reading rate of different factors, among which the product type, the gate configuration, the field polarisation, the power output of the RF reader, the interrogation protocol configuration as well as the transit speed, the number of tags and their interactions were statistically analysed and compared.

Full textAbstract:
If torture is both ethically odious and usually ineffective as an interrogation method, why have states, especially democratic ones, practiced it? This paper develops a theoretical response to this puzzle by extending constructivist understandings of normative effects. I argue that the norm prohibiting torture has the perverse effect of making torture more attractive to some political leaders in two ways: first, the norm attracts those who are looking for an outside-the-box solution to challenging intelligence-gathering scenarios; second, the norm offers political leaders a narrative of heroism in which they sacrifice their morality for the greater good. I illustrate these explanations with the example of torture in the United States war on terror. My argument suggests that norms can shape the interests even of those who do not follow their scripts, implying that the scope of normative impact may be much wider than previously believed.

Full textAbstract:
Black Feminist Health Science Studies (BFHSS) is a critical intervention into a number of intersecting arenas of scholarship and activism, including feminist health studies, contemporary medical curriculum reform conversations, disability studies, environmental justice, and feminist technoscience studies (Bailey, 2016). We argue towards a theory of BFHSS that builds on social justice science, which has as its focus the health and well-being of marginalized groups. We would like to move towards a social justice science that understands the health and well-being of people to be its central purpose. This formulation of BFHSS provides evidence of the co-constitutive nature of medical science and popular perception, underscoring the need to engage them simultaneously. Health is both a desired state of being and a social construct necessary of interrogation because of the ways that race, gender, able bodiedness, and other aspects of cultural production profoundly shape our notions of what is healthy (Metzl & Kirkland, 2010).

Full textAbstract:
Voltage-gated potassium (Kv) channels regulate the membrane potential and conductance of excitable cells to control the firing rate and waveform of action potentials. Even though Kv channels have been intensely studied for over 70 year, surprisingly little is known about how specific channels expressed in various neurons and their functional properties impact neuronal network activity and behavior in vivo. Although many in vivo genetic manipulations of ion channels have been tried, interpretation of these results is complicated by powerful homeostatic plasticity mechanisms that act to maintain function following perturbations in excitability. To better understand how Kv channels shape network function and behavior, we have developed a novel optogenetic technology to acutely regulate Kv channel expression with light by fusing the light-sensitive LOV domain of Vaucheria frigida Aureochrome 1 to the N-terminus of the Kv1 subunit protein to make an Opto-Kv1 channel. Recording of Opto-Kv1 channels expressed in Xenopus oocytes, mammalian cells, and neurons show that blue light strongly induces the current expression of Opto-Kv1 channels in all systems tested. We also find that an Opto-Kv1 construct containing a dominant-negative pore mutation (Opto-Kv1(V400D)) can be used to down-regulate Kv1 currents in a blue light-dependent manner. Finally, to determine whether Opto-Kv1 channels can elicit light-dependent behavioral effect in vivo, we targeted Opto-Kv1 (V400D) expression to Kv1.3-expressing mitral cells of the olfactory bulb in mice. Exposure of the bulb to blue light for 2–3 hours produced a significant increase in sensitivity to novel odors after initial habituation to a similar odor, comparable to behavioral changes seen in Kv1.3 knockout animals. In summary, we have developed novel photoactivatable Kv channels that provide new ways to interrogate neural circuits in vivo and to examine the roles of normal and disease-causing mutant Kv channels in brain function and behavior.

Full textAbstract:
This review paper describes the destructive and non-destructive measurements implemented or under development at CEA, in view to perform the most complete radioactive waste characterization. First, high-energy photon imaging (radiography, tomography) brings essential information on the waste packages, such as density, position and shape of the waste inside the container and in the possible binder, quality of coating and blocking matrices, presence of internal shields or structures, presence of cracks, voids, or other defects in the container or in the matrix, liquids or other forbidden materials, etc. Radiological assessment is then performed using a series of non-destructive techniques such as gamma-ray spectroscopy, which allows characterizing a wide range of radioactive and nuclear materials, passive neutron coincidence counting and active neutron interrogation with the differential die-away technique, or active photon interrogation with high-energy photons (photofission), to measure nuclear materials. Prompt gamma neutron activation analysis (PGNAA) can also be employed to detect toxic chemicals or elements which can greatly influence the above measurements, such as neutron moderators or absorbers. Digital auto-radiography can also be used to detect alpha and beta contaminated waste. These non-destructive assessments can be completed by gas measurements, to quantify the radioactive and radiolysis gas releases, and by destructive examinations such as coring homogeneous waste packages or cutting the heterogeneous ones, in view to perform visual examination and a series of physical, chemical, and radiochemical analyses on samples. These last allow for instance to check the mechanical and containment properties of the package envelop, or of the waste binder, to measure toxic chemicals, to assess the activity of long-lived radionuclides or pure beta emitters, to determine the isotopic composition of nuclear materials, etc.

Full textAbstract:
Optical fiber ball resonators based on single-mode fibers in the infrared range are an emerging technology for refractive index sensing and biosensing. These devices are easy and rapid to fabricate using a CO2 laser splicer and yield a very low finesse reflection spectrum with a quasi-random pattern. In addition, they can be functionalized for biosensing by using a thin-film sputtering method. A common problem of this type of device is that the spectral response is substantially unknown, and poorly correlated with the size and shape of the spherical device. In this work, we propose a detection method based on Karhunen−Loeve transform (KLT), applied to the undersampled spectrum measured by an optical backscatter reflectometer. We show that this method correctly detects the response of the ball resonator in any working condition, without prior knowledge of the sensor under interrogation. First, this method for refractive index sensing of a gold-coated resonator is applied, showing 1594 RIU−1 sensitivity; then, this concept is extended to a biofunctionalized ball resonator, detecting CD44 cancer biomarker concentration with a picomolar-level limit of detection (19.7 pM) and high specificity (30–41%).

Abstract This text considers the “Archive” as a concept and a transitional space and to bring together discussions from history and organizations in relation to theoretical and methodological concerns involving the use of archives. It sets out from the supposition that broadening our understanding of these terms may support historical research in Management to advance new questions about of a range of objects, including documents and archives. During this process we focus on the changes brought about by advances in information technology, particularly the internet, and put forward certain considerations concerning Organization Studies that rely on archives. The conclusion indicates that archives and the Archive are constituent elements of practices and structures, and that the field would benefit from a research agenda that took into consideration: 1) greater methodological awareness about the implications of the use of documents and archives; 2) discussions about organizations that archive and how archives shape practices within these organizations; 3) studies of already available documents, including those online; 4) an interrogation of knowledge in Management in relation to Archives.

In 2002 Karín Lesnik-Oberstein and Stephen Thomson published an essay entitled “what is queer theory doing with the child?,” addressing work in the 1990s by Michael Moon and the late, great Eve Kosofsky Sedgwick on the “protogay” child. Something inappropriate, even scandalous, was their answer, as one might surmise from the accusatory shape of the question. In their reading, Moon and Sedgwick essentialize rather than interrogate the protogay child, such that said child becomes “an anti-theoretical moment, resistant to analysis, itself the figure deployed as resistance” (36). For Lesnik-Oberstein and Thomson, queer theory is insufficiently alert to the lessons of poststructuralist theory and especially to the ongoing interrogation of “child” and “childhood.” Lesnik-Oberstein and Thomson specialize in childhood studies, and Lesnik-Oberstein is a well-known scholar of children's literature. Her 1994 Children's Literature: Criticism and the Fictional Child extends and takes inspiration from Jacqueline Rose's The Case of Peter Pan; or, The Impossibility of Children's Fiction (1984), which ushered into children's literature studies a powerful and lasting skepticism about “childhood” and “children's literature.”

Full textAbstract:
The design of mechanical structural parts is now predominantly a digital process. As an important element of the virtual design cycle, these parts must be tested for their structural integrity using finite element analysis (FEA) software. However, the interface between CAD and FEA is imperfect. The process of preparing CAD models for FEA consumes a great deal of the stress analyst’s time. Existing “automatic” CAD to FEA translators tend to treat all part features as “solid”; this leads to longer computation times and less accurate results for features that can be better characterized as “thin” or “long.” In addition, many features of CAD parts (e.g. fillets and chamfers) are important for their size and shape in the manufactured product, but have relatively little impact on the strength of the part and needlessly complicate the stress analysis—these features are usually removed by the analyst prior to FEA; they may need to be evaluated with additional analyses to test if it is safe to remove them. The Automatic CAD-FEA Interface Project (ACFI), is developing algorithms to make the translation from CAD to FEA seamless and automatic; these algorithms are based on mathematical theory and the principles of theoretical mechanics. This paper presents the latest ACFI advances for (i) automatically evaluating and reworking three dimensional CAD part geometries to prepare them for finite element meshing, (ii) exporting the revised geometries to a preprocessor, and (iii) identifying element type to be associated with each feature geometry. The algorithms used in this work approximate the medial axis transform (MAT) of the CAD part, a “power shape” that represents the three-dimensional solid part. This part can then be evaluated for its geometric properties. This approach has been shown to be a robust method for shape interrogation of three dimensional geometries.

Full textAbstract:
The concerns of mental health professionals about the psychological characteristics and behaviour of political leaders forces a rethinking of their professional and social responsibility, especially in the context of the Goldwater Rule that applies to psychiatrists in the United States. Despite the fact that this ethical guideline does not pertain to Psychology professionals or the African continent, it is worthy of discussion and interrogation, considering the prevalence of poor leadership internationally, and the need for the previously colonised world to ensure independent and critical thinking on such matters. The article questions the traditional, narrow focus of psychologists and other mental health specialists in conceptualising professional and ethical roles, and raises the issue of their professional and social responsibility to help shape society and its democratic processes. Psychologists, psychiatrists, and others have much to contribute in this respect and they have to question the ethical and social responsibility impact of remaining silent in the face of behaviourally and psychologically maladjusted individuals being elected to high offices such as President and other influential positions. These professionals must adopt a public health approach that always has in mind the well-being of the broader society.

Full textAbstract:
Wavelet transform has emerged as a powerful tool for time-frequency analysis and signal coding favored for the interrogation of complex non-stationary signals such as the ECG signal. Measurement of timing intervals of ECG signal by automated system is highly superior to its subjective analysis. The timing interval is found from the onset and offset of the wave components of the ECG signal. Since the Daubechies wavelet is similar to the shape of the ECG signal, better detection is achieved. Discrete Wavelet Transform is easier to implement, provides multiresolution and also reduces the computational time, and thus, is used. In the pre-processing step, the base line wandering is removed from the ECG signal. Then the R peak and the QRS complexes are detected. Twenty five records from the MIT-BIH arrhythmia database are used to evaluate the proposed method. Sensitivity and positive prediction are used as performance measures. This method is very simple and detects all the R peaks (sensitivity = 100% and positive prediction = 99.86%). That is, false positive detection is very negligible and false negative detection is zero. The performance of the proposed method is better than other methods that exist in the literature.

Full textAbstract:
In December 2014, Physicians for Human Rights (PHR) released their analysis of the summary of the Committee Report of the Central Intelligence Agency’s Detention and Interrogation Program. PHR focused on the involvement of health care professionals in the CIA torture program, concluding that the health professionals’ commissions and omissions violated the prescriptions of many fundamental bioethical documents, including international declarations of bioethics and medical research ethics. The medical doctors’ involvement evokes some thoughts concerning bioethical education. It seems that instead of developing virtues through practicing morally good habits, the experience of clinical training undermines the moral ideals that medical students identified themselves with at the commencement of their medical education. The hostile response they sometimes get from their mentors when trying to question morally troubling situations may shape the habit of ‘turning a blind eye’ to unethical behaviour, since the students do not want to jeopardize their grades and future medical career. Maybe it was the development of this habit and the failure to develop the habit of moral courage instead that prevented the medical doctors participating in torture programs from defending moral ideals of their profession more effectively.

Full textAbstract:
The use of single crystal (SX) nickel-base superalloys will increase in the future with the introduction of SX blades into large gas turbines for base-load electricity production. Prolonged periods of use at high temperatures may cause creep deformation and the assessment of damage can give large financial savings. A number of techniques can be applied for life assessment, e.g., calculations based on operational data, nondestructive testing or material interrogation, but because of the uncertainties involved the techniques are often used in combination. This paper describes a material interrogation (metallographic) technique for creep strain assessment in SX alloys. Creep tests have been performed at 950°C on the SX alloy CMSX-4 and quantitative microstructural studies performed on specimens interrupted at various levels of strain. It was found that the strengthening γ′-particles, initially cuboidal in shape, coalesced to form large plates or rafts normal to the applied stress. The γ-matrix phase also formed plates. CMSX-4 contains ∼70 vol % γ-particles and after creep deformation the microstructure turned itself inside out, i.e., the gamma “matrix” became the isolated phase surrounded by the γ′-“particles.” This can cause problems for computerized image analysis, which in this case, were overcome with the choice of a suitable measurement parameter. The rafts reached their maximum length before 2 percent strain, but continued to thicken with increasing strain. Although of different dimensions, the aspect ratios (length/thickness ratio) of the gamma-prime rafts and the gamma plates were similar at similar levels of strain, increasing from ∼1 at zero strain to a maximum of ∼ 3 at about 1–2 percent strain. Analysis of microstructural measurements from rafting studies on SX alloys presented in the literature showed that the aspect ratios of the γ and γ′-phases were similar and that at a temperature of 950–1000°C a maximum length/thickness ratio of about 2.5–3.5 is reached at 1 to 2 percent creep strain. Measurement of gamma-prime raft or (or gamma plate) dimensions on longitudinal sections of blades is thus a suitable method for high temperature creep damage assessment of SX alloys. This gives a considerable advantage over conventional Ni-base superalloys whose microstructures are usually very stable with respect to increasing creep strain.

Full textAbstract:
Nanomaterials have made a rebellion in biomedical application especially treating several diseases due to its distinctive compositions. However, increased utilization of nanomaterials in biomedical applications has made an initiative to understand the possible interaction between the nanomaterials with the biological systems. These tiny particles enter into the body very easily and affect vulnerable systems which raise the interrogation of their potential effects on the susceptible organs. It is very crucial to comprehend the various exposure pathways, their movement, behavior and ultimate outcome. Specific and unique physicochemical properties, such as particle size and distribution, surface area, charge and coatings, particle shape/ structure, dissolution and aggregation, influence the nanomaterial interactions with cells. Toxicities in biological systems occurs as a result of a result of a variety of reasons including the production of ROS reactive oxygen species, degradation of the integrity of membrane and release of toxic metal ions thus preventing normal cell function. Various researchers have provided promising evidence that nanomaterial’s actively encompass and mediate chemical processes of cell, in addition to their passive interactions with cells. Certainly, it is very much essential to understand the possible toxic interactions of nanomaterial’s with the biological system as Nano toxicology. In this review, we emphasize the toxicological effects on different organs pertaining to nanomaterial-biological system interaction

This article critically interrogates how borders are produced by scientists, engineers and security experts in advance of the deployment of technical devices they develop. We trace how sovereign decisions are enacted as assemblages in the antecedent register of device development through the everyday decisions of scientists and engineers in the laboratory, the security experts they engage, and the material components of the device itself. Drawing on in-depth interviews, observations, and ethnographic research of the EU-funded Handhold project, we explore how assumptions about the way security technologies will and should perform at the border shape the development of a portable, integrated device to detect chemical, biological, radiological, nuclear and explosives (CBRNE) threats at borders. In disaggregating the moments of sovereign decision-making across multiple sites and times, we question the supposed linearity of how science comes out of and feeds back into the world of border security. An interrogation of competing assumptions and understandings of security threats and needs, of competing logics of innovation and pragmatism, of the demands of differentiated temporalities in detection and identification, and of the presumed capacities, behaviours, and needs of phantasmic competitors and end-users reveals a complex, circulating and co-constitutive process of device development that laboratises the border itself.

Full textAbstract:
The contact with nature provided by urban green and blue space is said to be beneficial for mental health, physical health, social contact and cohesion, and for learning and development among children. Yet the literature identifying these benefits fails to recognise that ‘nature’, as a category in binary relation with ‘culture’ (or ‘humans’), is a cultural construct. Acknowledging this inevitably raises questions about exactly what ‘contact with nature’ in such spaces might consist in. Taking inspiration from more-than-representational and more-than-human geographies, this article uses Merleau-Ponty’s phenomenology to interrogate encounters with ‘nature’ through small boat sailing. I argue that being on a boat entails different embodied spatialities of being from terrestrial urban life, and that this heightens a sense of nature as Other. The nature/culture binary, while a cultural idea, is materially (re)produced through the ordering of space, particularly in dense urban areas. This implies that the significance of urban green/blue space may be not only the presence of non-humans (the green/blue) but also the nature of the space in which we encounter nature. There is, then, potential for cultural geography to contribute to a much more nuanced interrogation of how people experience urban green/blue space, foregrounding the cultural conditions that shape such experience.

We report the design, fabrication, and testing of a humidity sensor based on an optical fiber-based evanescent wave probe. The fiber was bent into a U-shape and de-cladded at the location of the bending. The de-cladded section was coated either with Au or with ZnO nanoparticles. Humidity is detected based on the interaction in the surface plasmon resonance of the Au/ZnO nanoparticles excited by an evanescent wave of light passing through the optical fiber. The response of the U-bent fibers to humidity was investigated using a specifically designed low-voltage portable interrogation box. We found that the fibers coated with ZnO nanoparticles were able to detect a minimum 0.1% change in humidity with an average sensitivity of 143 µV/%RH and 95% linearity over the 10% to 80% humidity range. In comparison, samples coated with Au and Au + ZnO nanoparticles demonstrated a minimum change detection of 0.3% RH and 2% RH respectively. The response and recovery time of the sensor were measured to be 3 s and 4 s, respectively, for a 60% change in humidity from 20% to 80%. The entire measurement system was operated by consuming an electrical power of 1.62 W at an input voltage of 12 Vdc.

Background This chapter explores player interactions and engagement in tabletop role-playing game settings. Objective Particularly focusing on the intersection of gaming systems, virtual settings, and player interactions, this chapter seeks to explore how implicit systems shape individuals’ experiences and behaviors. Through this focus, the chapter intentionally draws parallels between informal gaming settings and classroom-based interactions. Setting Though this study makes specific connections to classroom pedagogies, data were collected from a multiyear ethnographic study of playing tabletop role-playing games with adult participants in informal learning environments. Data were collected from within public gaming cafes and shops. Research Design Participant observation within a role-playing game community served as the primary approach to this ethnographic study. In addition to fieldnote-based observation, interviews with players and archival analysis of gaming artifacts helped triangulate meaning-making at the gaming table. Analysis was conducted through an inductive coding approach that focused on player interactions, systems, and settings. Findings Cultural values, including racism and sexism, shaped player experiences at the table, based on systemic designs and textual guidance from game-related fiction. While games speak to broad possibilities for exploring race and gender, these constructs become limited through the layers of player beliefs, designed rule sets, and depictions within narratives. The emancipatory possibilities of ludic imagination are flattened by cultural norms that may oppress. Conclusions Broadening the findings from this study, this chapter concludes with classroom-based recommendations. If a contemporary approach to critical pedagogy depends on dialogue and cultural understanding, this chapter points to the limitations of confining such work to traditional classroom settings. Instead, it suggests that an interrogation of these systems, alongside youth, is a necessary step in critically oriented classrooms.

Our objectives were to robustly characterize a cohort of Holstein cows for udder and teat type traits and perform high-density genome-wide association studies for those traits within the same group of animals, thereby improving the accuracy of the phenotypic measurements and genomic association study. Additionally, we sought to identify a novel udder and teat trait composite risk index to determine loci with potential pleiotropic effects related to mastitis. This approach was aimed at improving the biological understanding of the genetic factors influencing mastitis. Cows (N = 471) were genotyped on the Illumina BovineHD777k beadchip and scored for front and rear teat length, width, end shape, and placement; fore udder attachment; udder cleft; udder depth; rear udder height; and rear udder width. We used principal component analysis to create a single composite measure describing type traits previously linked to high odds of developing mastitis within our cohort of cows. Genome-wide associations were performed, and 28 genomic regions were significantly associated (Bonferroni-corrected p < 0.05). Interrogation of these genomic regions revealed a number of biologically plausible genes whicht may contribute to the development of mastitis and whose functions range from regulating cell proliferation to immune system signaling, including ZNF683, DHX9, CUX1, TNNT1, and SPRY1. Genetic investigation of the risk composite trait implicated a novel locus and candidate genes that have potentially pleiotropic effects related to mastitis.

Abstract What insights into literary realism can be found by dwelling in the empty rooms and abandoned spaces of Bleak House, a novel more often read for its representation of overcrowded environments? Traveling between and imaginatively inhabiting empty houses of Charles Dickens's and Virginia Woolf's construction, this article proposes empty-house-time as a distinctive narrative chronotope, one that nineteenth- and twentieth-century British writers use to investigate the processes of realist fiction, especially its affective dimensions. Taking the character-less built environment as a figure for the novel form, the article shows that the chromatic present that characterizes narratives of spaces like Chesney Wold when the Dedlocks are absent throws into flux boundaries between the fictional and the real, the reader and the world of the text, and different modes of imagining. It opens up continuums along which strategies of realist characterization and world-building are dramatized and interrogated. Most powerfully, empty-house-time reveals how affects associated with imagining the world going on without you shape encounters with fiction. Identifying the vital, ongoing existence of unoccupied rooms in Dickens's writing can in turn revitalize studies of the relationship between Victorian and modernist novels and theories of realism. This article concludes by turning to the Ramsays’ abandoned coastal home in To the Lighthouse, in which Woolf, like Dickens, links an interrogation of realist fictionality to a historically specific reimagining of the household.

Full textAbstract:
Martin McDonagh's The Pillowman dramatizes the interrogation and torture of a horror fiction writer, Katurian, whose stories have been re-enacted in ‘real’ life without his knowledge. The audience gradually finds out that the murders are the crimes of Michal, Katurian's mentally retarded brother, who had been physically tortured by his parents in childhood, until Katurian murdered them. Upon Michal's confession, Katurian has to kill his brother to save him from the suffering and torture to come. Subsequently, it becomes clear that the two interrogators also suffer from the violent childhoods they re-enact with the violence they inflict on their suspects. It appears that all kinds of violence in the play are somehow justified, and treated in such a complex way that it becomes hard to draw boundaries between victims and perpetrators.
