Tunable High-Q N-Path Band-Pass Filters: Modeling and Verification

A differential single-port switched-RC N-path filter with band-pass characteristic is proposed. The switching frequency defines the center frequency, while the RC-time and duty cycle of the clock define the bandwidth. This allows for high-Q highly tunable filters which can for instance be useful for cognitive radio. Using a linear periodically time-variant (LPTV) model, exact expressions for the filter transfer function are derived. The behavior of the circuit including non-idealities such as maximum rejection, spectral aliasing, noise and effects due to mismatch in the paths is modeled and verified via measurements. A simple RLC equivalent circuit is provided, modeling bandwidth, quality factor and insertion loss of the filter. A 4-path architecture is realized in 65 nm CMOS. An off-chip transformer acts as a balun, improves filter-Q and realizes impedance matching. The differential architecture reduces clock-leakage and suppresses selectivity around even harmonics of the clock. The filter has a constant -3 dB bandwidth of 35 MHz and can be tuned from 100 MHz up to 1 GHz. Over the whole band, IIP3 is better than 14 dBm, P1dB=2 dBm and the noise figure is 3-5 dB, while the power dissipation increases from 2 mW to 16 mW (only clocking power).
Smart Schools for saving the soul: a juxtaposition of neofundamentalist and neoliberal discourse concentrations in contemporary Malaysia

This paper reports on an analysis of public documents produced by the government of Malaysia for the purpose of guiding the enactment of educational technology efforts in Malaysia. The analysis explores the concentration of discourses that make possible certain framings of technology in educational contexts that seek to act upon the notions of citizenship and identity among Muslims in Malaysia. Using the lenses of neofundamentalism and neoliberalism and leveraging analysis methods from the grounded theory methodological tradition, this study examined the ways the Malaysian government works on constructing the identities of its young Muslim citizenry by way of policy initiatives for the implementation of educational technologies. Sixteen documents produced and published by the Malaysian government served as the data for the analysis. Findings indicate that a neofundamentalist governmental rhetoric insists on looking to the past nostalgically and to non-rational textual hermeneutics for interpretations of Islam. At the same time, neoliberalism underpins discourses on educational technology and ‘wealth-making’ contemporary discourses on education and particularly educational technology. This produces a situation in which contemporary Malaysian government citizen work is locked in a crisis of bilateral nostalgia whereby a technology-rich and materially wealthy future is anticipated simultaneously with a longing for an Islamic civilization rooted in past traditionalisms and spiritualities. The Malaysian government then works a form of alchemy to manage this ironic tension.
Seamless Flow Migration on Smartphones without Network Support

This paper addresses the following question: Is it possible to migrate TCP/IP flows between different networks on modern mobile devices, without infrastructure support or protocol changes? To answer this question, we make three research contributions. (i) We report a comprehensive characterization of IP traffic on smartphones using traces collected from 27 iPhone 3GS users for three months. (ii) Driven by the findings from the characterization, we devise two novel system mechanisms for mobile devices to sup-port seamless flow migration without network support, and extensively evaluate their effectiveness using our field collected traces of real-life usage. Wait-n-Migrate leverages the fact that most flows are short lived. It establishes new flows on newly available networks but allows pre-existing flows on the old network to terminate naturally, effectively decreasing, or even eliminating, connectivity gaps during network switches. Resumption Agent takes advantage of the functionality integrated into many modern protocols to securely resume flows without application intervention. When combined, Wait-n-Migrate and Resumption Agent provide an unprecedented opportunity to immediately deploy performance and efficiency-enhancing policies that leverage multiple networks to improve the performance, efficiency, and connectivity of mobile devices. (iii) Finally, we report an iPhone 3GS based implementation of these two system mechanisms and show that their overhead is negligible. Furthermore, we employ an example network switching policy, called AutoSwitch, to demonstrate their performance. AutoSwitch improves the Wi-Fi user experience by intelligently migrating TCP flows between Wi-Fi and cellular networks. Through traces and field measurements, we show that AutoSwitch reduces the number of user disruptions by an order of magnitude.
Using circular programs for higher-order syntax: functional pearl

This pearl presents a novel technique for constructing a first-order syntax tree directly from a higher-order interface. We exploit circular programming to generate names for new variables, resulting in a simple yet efficient method. Our motivating application is the design of embedded languages supporting variable binding, where it is convenient to use higher-order syntax when constructing programs, but first-order syntax when processing or transforming programs.
Use of Semi-Formal and Formal Methods in Requirement Engineering of ILMS

A systematic approach in requirement engineering helps in discovering and understanding the requirements at different levels of abstraction as well as makes the requirements traceable and verifiable early in the project. This paper presents a methodology for requirement engineering by using a combination of formal and semiformal techniques to model software requirements for analysis and verification. The proposed framework incorporates requirement-analysis and requirement-verification models, which are guided by the Domain Model represented by a Conceptual Class diagram and the defined Ontology. The proposed approach is particularly useful when requirements are defined in hierarchical levels of abstraction and traceability between a requirement at a detailed level and its correspondence at an abstract level is required. The proposed framework also allows verification of the accordance of the requirements with respect to the Domain Model. The requirement analysis model at each level of abstraction is represented by a combination of three different modeling techniques: Conceptual Graph, Use-Case diagram and VDM-SL specification. A verification model to ensure traceability between the requirements at different abstraction levels, using a three-dimensional schema, is also proposed. The Requirements of an Intelligent Learning Management System are used as an example to illustrate the proposal.
Doing and rethinking. Building resilience with men

Purpose – The purpose of this paper is to present findings from an evaluation of a mental health resilience intervention for unemployed men aged 45-60. The focus is on examining the place of activities within a multi-dimensional men’s mental health programme, and exploring interactions between social context factors and models of change. Design/methodology/approach – The paper draws on before and after survey data and qualitative interviews, to report results concerning effectiveness in changing men’s perceived resilience, to consider project processes concerning activities, social support and coping strategies, and to situate these within wider environments. Findings – The programme significantly raised the perceived resilience of participants. Activities were engaging for men, while the complex intersection between activities, social networking, and coping strategies course provided opportunities for men to develop resilience in contexts resonant with their male identities.

PRESENT STATE EXAMINATION

1974. Pp. ii+ 526. Price J2.75. Frank Fish, before his untimely death Professor of Psychiatry in the University of Liverpool, conducted a series ofseminars in Canada on the phenomenology of mental illness. Subsequently he decided to publish the results of his preparatory studies, on the correct assumption that a descriptive account of psycho pathology might help to fill a gap in English psychia tric literature. The gap was in fact so big that the book soon went out of print and has been posted â€ ̃¿ missing' in at least one hospital library. The reviewer was fortunate enough to be able to borrow a copy from a friend, and this allows him to testify that Professor Max Hamilton has revised the reprint in a way which has not altered the book's original format or tone. Thus Frank Fish had a few pungent things to say about certain psychiatrists, and Max Hamilton adds a few more well-directed blows ! He has been very sparing in cutting or adding to the original text and wherever they have been spotted by the reviewer these changes seem to present an improvement. This small volume is based on great erudition and communicates a goodly amount of information. It demonstrates the need for the correct use of words, for clear thinking, and for meticulous precision, even though in certain areas precision might be regarded as excessive because unrealistic. There are lengthy discussions about matters like primary delusions, delusion-like ideas, over-valued ideas, delusional mood, delusional perceptions, etc. One wonders how often it is really possible to distinguish precisely between symptoms of this sort in view of the difficulties in communicating with all except the more sophisticated and well-spoken psychotic patients; even if one feels satisfied that these finer psychopathological shadings are valid and not just artefacts of prolonged contact between philoso phically-minded German psychiatrists and their pet chronic patients! Nowadays problems concerning the correct assessment of psychopathology arise much more urgently in relation to schizophrenic and affective patients receiving insufficient pharma cological treatment or other inadequate therapies. A sound knowledge of descriptive psychopathology is essential in the recognition and evaluation of vestigial
Protective Effects of Parental Monitoring on Offending in Victimized Youth in Bosnia and Herzegovina

Empirical and conceptual literature in the United States and Western Europe provides robust evidence of victimization as a risk factor for juvenile offending and parental monitoring as a protective factor. The current study examines relationships among victimization, monitoring, and offending using a sample of youth from Bosnia and Herzegovina (BiH). Findings indicate monitoring has a protective effect, victimization increases risk, monitoring level moderates the effect of victimization on offending, and moderation effects vary by age and gender. Discussion of findings identifies implications for efforts in BiH to develop a comprehensive strategy for preventing and responding to juvenile offending.
A Novel 3D Hybrid FEM-PO Technique for the Analysis of Scattering Problems

A novel three-dimensional hybrid Finite Element Method (FEM) and Physical Optics (PO) technique for the efficient analysis of scattering problems is presented. It makes use of FEM for the regions with small and complex features and PO for the analysis of the electrically large objects of the structure taking into account mutual interactions between the FEM domains and the objects analyzed with PO. The hybrid method proposed makes use of an iterative FEM for open region problems that allows the FEM domain to be truncated with a minimum number of unknowns while retaining the original sparse and banded structure of the FEM matrices, and also an easy hybridization with other numerical techniques (as PO in this paper). Several numerical results are given showing some of the features of the method.
Investigation of possible microcavity effect on lasing threshold of nonradiative-scattering-dominated semiconductor lasers

The effect of enhanced rate of spontaneous emission on gain and lasing threshold of semiconductor microcavity lasers has not been discussed clearly. Some reports have suggested that the lasing threshold in microcavities could possibly be lowered due to the so-called Purcell effect. Here, we argue that gain in weakly coupled semiconductor cavities is a local phenomenon, which occurs due to stimulated emission induced by an electromagnetic excitation and remains unaffected by the cavity boundary conditions. Hence, the Purcell effect in microcavities filled uniformly with a gain medium should not lead to a reduction in the laser’s threshold pump density, provided radiative scattering is not the dominant relaxation mechanism in the excited state. A systematic experimental investigation of laser threshold in parallel-plate semiconductor microcavity terahertz quantum-cascade lasers of different dimensions was found to be in accordance with our arguments.
Contrasting effects of NO and peroxynitrites on HSP70 expression and apoptosis in human monocytes.

The free radicals nitric oxide (.NO) and superoxide (O(2)(-). ) react to form peroxynitrite (ONOO(-)), a highly toxic oxidant species. In this study we investigated the respective effects of NO and ONOO(-) in monocytes from healthy human donors. Purified monocytes were incubated for 6 or 16 h with a pure NO donor (S-nitroso-N-acetyl-DL-penicillamine, 0-2 mM), an.NO/ONOO(-) donor (3-morpholinosydnonimine chlorhydrate, 0-2 mM) with and without superoxide dismutase (200 IU/ml), or pure ONOO(-). We provide evidence that 3-morpholinosydnonimine chlorhydrate alone represents a strong stress to human monocytes leading to a dose-dependent increase in heat shock protein-70 (HSP70) expression, mitochondrial membrane depolarization, and cell death by apoptosis and necrosis. These phenomena were abolished by superoxide dismutase, suggesting that ONOO(-), but not.NO, was responsible for the observed effects. This observation was further strengthened by the absence of a stress response in cells exposed to S-nitroso-N-acetyl-DL-penicillamine. Conversely, exposure of cells to ONOO(-) alone also induced mitochondrial membrane depolarization and cell death by apoptosis and necrosis. Thus ONOO(-) formation may well explain the toxic effect generally attributed to.NO.

Endoscopic ultrasound-guided fine needle aspiration of pancreatic lesions with 22 versus 25 Gauge needles: A meta-analysis

Background Robust data in favour of a clear superiority of 22 versus 25 Gauge needles for endoscopic ultrasound-guided fine needle aspiration are still lacking. Objective We aimed to compare the diagnostic sensitivity, specificity and safety of these two needles for endoscopic ultrasound-guided fine needle aspiration of solid pancreatic lesions. Methods A computerized bibliographic search was restricted to randomized controlled trials only. Pooled effects were calculated using a random-effects model and expressed in terms of risk ratio and 95% confidence interval. Results We analysed seven trials with 689 patients and 732 lesions (295 sampled with 22 Gauge needle, 309 with 25 Gauge needle, and 128 with both needles). A non-significant superiority of 25 Gauge in terms of pooled sensitivity (risk ratio: 0.93, 0.91–0.95 versus 0.89, 0.85–0.94 of 22 Gauge needle; p = 0.13) and no difference in terms of specificity (1.00, 0.98–1.00 in both groups; p = 0.85) were observed. Sample adequacy was similar between the two devices (risk ratio: 1.03, 0.99–1.06; p = 0.15). Very few adverse events were observed and did not impact on patient outcomes. Conclusion Our meta-analysis reveals non-superiority of 25 Gauge over 22 Gauge; hence no definitive recommendations over the use of one particular device can be made.
Storage management for objects in EXODUS

In the 1970’s, the relational data model was the focus of much of the research in the database area. At this point, relational database technology is well-understood, a number of relational systems are commercially available, and they support the majority of business applications relatively well. One of the foremost database problems of the 1980’s is how to support classes of applications that are not well-served by relational systems. For example, computer-aided design systems, scientific and statistical applications, image and voice applications, and large, data-intensive AI applications all place demands on database systems that exceed the capabilities of relational systems. Such application classes differ from business applications in a variety of ways, including their data modeling needs, the types of operations of interest, and the storage structures and access methods required for their operations to be efficient.
Ellipsoid clustering machine: a front line to aid in disease diagnosis

This study presents a new machine learning strategy to address the disease diagnosis classification problem that comprises an unknown number of disease classes. This is exemplified by a software called Ellipsoid Clustering Machine (ECM) that identifies conserved regions in mass spectrometry proteomic profiles obtained from control subjects and uses these to estimate classification boundaries based on sample variance. The software can also be used for visual inspection of data reproducibility. ECM was evaluated using mass spectrometry protein profiles obtained from serum of Hodgkin’s disease patients (HD) and control subjects. According to the leave-one-out cross validation, ECM completely separated both groups based only on the information derived from four selected mass spectral peaks. Classification details and a 3D graphical model showing the separation between the control subject cluster and HD patients is also presented. The software is available on the project website together with online interactive models of the dataset and an animation demonstrating the method.
Multi-layered summarization of spoken document archives by information extraction and semantic structuring

The spoken documents are very difﬁcult to be shown on the screen, and very difﬁcult to retrieve and browse. It is therefore important to develop technologies to summarize the entire archives of the huge quantities of spoken documents in the network content to help the user in browsing and retrieval. In this paper we propose a complete set of multi-layered technologies to handle at least some of the above issues: (1) Automatic Generation of Titles and Sum-maries for each of the spoken documents, such that the spoken documents become much more easier to browse, (2) Global Semantic Structuring of the entire spoken document archive, offering to the user a global picture of the semantic structure of the archive, and (3) Query-based Local Semantic Structuring for the subset of the spoken documents retrieved by the user’s query, providing the user the detailed semantic structure of the relevant spoken documents given the query he entered. The Probabilistic Latent Semantic Analysis (PLSA) is found to be helpful, and an initial prototype system for the functions mentioned above has been successfully developed, in which the broadcast news archive in Mandarin Chinese is taken as the example archive.
Using the K-Nearest Neighbor Algorithm for the Classification of Lymph Node Metastasis in Gastric Cancer

Accurate tumor, node, and metastasis (TNM) staging, especially N staging in gastric cancer or the metastasis on lymph node diagnosis, is a popular issue in clinical medical image analysis in which gemstone spectral imaging (GSI) can provide more information to doctors than conventional computed tomography (CT) does. In this paper, we apply machine learning methods on the GSI analysis of lymph node metastasis in gastric cancer. First, we use some feature selection or metric learning methods to reduce data dimension and feature space. We then employ the K-nearest neighbor classifier to distinguish lymph node metastasis from nonlymph node metastasis. The experiment involved 38 lymph node samples in gastric cancer, showing an overall accuracy of 96.33%. Compared with that of traditional diagnostic methods, such as helical CT (sensitivity 75.2% and specificity 41.8%) and multidetector computed tomography (82.09%), the diagnostic accuracy of lymph node metastasis is high. GSI-CT can then be the optimal choice for the preoperative diagnosis of patients with gastric cancer in the N staging.
Laser printing hierarchical structures with the aid of controlled capillary-driven self-assembly

Significance We propose a strategy to realize designable hierarchical functional structures via laser printing capillary-assisted self-assembly (LPCS). Ultrafast laser printing is applied for building unit blocks and capillary force is finely tuned as driving force. Diverse structures are successfully fabricated by controlling the spatial arrangements, heights, diameters of pillars, and the evaporation process. The ability of these LPCS structures to selectively trap and release microobjects suggests enormous potential applications in the fields of chemistry, biomedicine, and microfluidic engineering. Capillary force is often regarded as detrimental because it may cause undesired distortion or even destruction to micro/nanostructures during a fabrication process, and thus many efforts have been made to eliminate its negative effects. From a different perspective, capillary force can be artfully used to construct specific complex architectures. Here, we propose a laser printing capillary-assisted self-assembly strategy for fabricating regular periodic structures. Microscale pillars are first produced by localized femtosecond laser polymerization and are subsequently assembled into periodic hierarchical architectures with the assistance of controlled capillary forces in an evaporating liquid. Spatial arrangements, pillar heights, and evaporation processes are readily tuned to achieve designable ordered assemblies with various geometries. Reversibility of the assembly is also revealed by breaking the balance between the intermolecular force and the elastic standing force. We further demonstrate the functionality of the hierarchical structures as a nontrivial tool for the selective trapping and releasing of microparticles, opening up a potential for the development of in situ transportation systems for microobjects.
