Using the Department of Labor’s “My Next Move” to Improve Career Preparedness

The Department of Labor’s Occupational Information Network can help students prepare for their careers because it contains information on over 900 occupations. Occupational Information Network includes a tool called My Next Move that is designed to help people learn about those occupations. This research uses a pretest/posttest design with a treatment group and a control group to determine if an exercise based on My Next Move improves career preparedness. Results show that the exercise produces significant increases in career awareness and in perceived career preparedness skills. The positive results indicate that this tool can help students be more knowledgeable about their career options after graduation. This article can help instructors use the My Next Move exercise to help students in their job search process.
Induced Gamma-band Activity Elicited by Visual Representation of Unattended Objects

Object recognition is achieved through neural mechanisms reliant on the activity of distributed neural assemblies that are thought to be coordinated by synchronous firing in the gamma-band range (>20 Hz). An outstanding question focuses on the extent to which the role of gamma oscillations in object recognition is dependent on attention. Attentional mechanisms determine the allocation of perceptual resources to objects in complex scenes biasing the outcome of their mutual competitive interactions. Would object-related enhancements in gamma activity also occur for unattended objects when perceptual resources are traded off to the processing of concurrent visual material? The present electroencephalogram study investigated event-related potentials and evoked (time- and phase-locked) and induced (non-time- and phase-locked to stimulus onset) gamma-band activity (GBA) using a visual discrimination task of low or high perceptual load at fixation. The task was performed while task-irrelevant familiar or unfamiliar objects coappeared in the surrounding central area. Attentional focus was kept at fixation by varying perceptual load between trials; in such conditions, only holistic object processing or low-level perceptual processing, requiring little or no attention, are thought to occur. Although evoked GBA remained unmodulated, induced GBA enhancements, specific to familiar object presentations, were observed, thus providing evidence for cortical visual representation of unattended objects. In addition, the effect was mostly driven by object-specific activity under low load, implying that, in cluttered or complex scenes, attentional selection likely plays a more significant role in object representation.
Radiation and concomitant chemotherapy for patients with glioblastoma multiforme

Postoperative external beam radiotherapy was considered the standard adjuvant treatment for patients with glioblastoma multiforme until the advent of using the drug temozolomide (TMZ) in addition to radiotherapy. High-dose volume should be focal, minimizing whole brain irradiation. Modern imaging, using several magnetic resonance sequences, has improved the planning target volume definition. The total dose delivered should be in the range of 60 Gy in fraction sizes of 1.8-2.0 Gy. Currently, TMZ concomitant and adjuvant to radiotherapy has become the standard of care for glioblastoma multiforme patients. Radiotherapy dose-intensification and radiosensitizer approaches have not improved the outcome. In spite of the lack of high quality evidence, stereotactic radiotherapy can be considered for a selected group of patients. For elderly patients, data suggest that the same survival benefit can be achieved with similar morbidity using a shorter course of radiotherapy (hypofractionation). Elderly patients with tumors that exhibit methylation of the O-6-methylguanine-DNA methyltransferase promoter can benefit from TMZ alone.
A Causal Framework for Credit Default Theory

Most existing credit default theories do not link causes directly to the effect of default and are unable to evaluate credit risk in a rapidly changing market environment, as experienced in the recent mortgage and credit market crisis. Causal theories of credit default are needed to understand lending risk systematically and ultimately to measure and manage credit risk dynamically for financial system stability. Unlike existing theories, credit default is treated in this paper by a joint model with dual causal processes of delinquency and insolvency. A framework for developing causal credit default theories is introduced through the example of a new residential mortgage default theory. This theory overcomes many limitations of existing theories, solves several outstanding puzzles and integrates both micro and macroeconomic factors in a unified financial economic theory for mortgage default.
Maximum Power Point Tracking Control of IPMSG Incorporating Loss Minimization and Speed Sensorless Schemes for Wind Energy System

In the variable-speed generation system, the wind turbine (WT) can be operated at maximum power operating points by adjusting the shaft speed optimally. This paper presents a novel maximum power point tracking (MPPT)-based control of interior permanent-magnet (IPM) synchronous generator incorporating loss minimization algorithm (LMA). In the proposed method, without requiring the knowledge of wind speed, air density, or turbine parameters, MPPT algorithm generates optimum speed command for speed control loop of vector-controlled machine side converter. The MPPT algorithm uses the estimated active power output of the generator as its input and generates command speed so that maximum power is transferred to the dc link. The proposed control system also incorporates a LMA to minimize the losses in the generator and hence to improve the efficiency of the wind energy conversion system (WECS). A speed sensorless scheme is also incorporated to increase the reliability of the system. The performance of the proposed adaptive MPPT control of wind generator incorporating loss minimization and speed sensorless schemes is tested in both simulation and experiment at variable wind speed conditions.
An Economic Theory of the GATT: A Generalization

Bagwell and Staiger (1999) conclude that the reason for governments to enter trade negotiation is the terms-of-trade externality, which creates an inefficiency in unilateral trade policies. To address this conclusion, the authors consider that protection may be motivated by many other objectives than just unilateral attempts at terns-of-trade improvements, including the desire to: (1) increase incomes (or prevent trade-driven losses) in import- competing countries; (2) increase employment; (3) improve the balance of trade. It may or may not be sensible for countries to increase tariffs for any of these reasons, but they do. In each case, trade agreements may be appealing to governments as a way to prevent an inefficiency that arises from unilateral trade policies. The justification for the GATT is that it restrains unilateral protection, regardless of its political or economic motivation. Moreover, this conclusion holds even if each country has a different motive for protection.
A Deep Generative Architecture for Postfiltering in Statistical Parametric Speech Synthesis

The generated speech of hidden Markov model (HMM)-based statistical parametric speech synthesis still sounds “muffled. ” One cause of this degradation in speech quality may be the loss of fine spectral structures. In this paper, we propose to use a deep generative architecture, a deep neural network (DNN) generatively trained, as a postfilter. The network models the conditional probability of the spectrum of natural speech given that of synthetic speech to compensate for such gap between synthetic and natural speech. The proposed probabilistic postfilter is generatively trained by cascading two restricted Boltzmann machines (RBMs) or deep belief networks (DBNs) with one bidirectional associative memory (BAM). We devised two types of DNN postfilters: one operating in the mel-cepstral domain and the other in the higher dimensional spectral domain. We compare these two new data-driven postfilters with other types of postfilters that are currently used in speech synthesis: a fixed mel-cepstral based postfilter, the global variance based parameter generation, and the modulation spectrum-based enhancement. Subjective evaluations using the synthetic voices of a male and female speaker confirmed that the proposed DNN-based postfilter in the spectral domain significantly improved the segmental quality of synthetic speech compared to that with conventional methods.
Stock Price Forecasting using Support Vector Machines and Improved Particle Swarm Optimization

The present paper employs an Particle Swarm Optimization (PSO) Improved via Genetic Algorithm (IPSO) based on Support Vector Machines (SVM) for efficient prediction of various stock indices. The main difference between PSO and IPSO is shown in a graph. Different indicators from the technical analysis field of study are used as input features. To forecast the price of a stock, the correlation between stock prices of different companies has been used. It is in general observed that the proposed model is computationally more efficient, prediction wise more accurate and more robust against other researches done by standard PSOSVM based model. 
The Reliability of a 5km Run Test on a Motorized Treadmill

ABSTRACT The purpose of the present study was to determine the reliability of a 5km run test on a motorized treadmill. Over three consecutive weeks, 12 well-trained runners completed three 5km time trials on a treadmill following a standardized warm-up. Runners were partially-blinded to their running speed and distance covered. Total time to complete the run was recorded for analysis of reliability. The highest intraclass correlation coefficient between trials for 5km time trial (TT) time was . 99 (90% confidence intervals [CI]; .96–1.00, very high), which occurred between trials 2 and 3. The lowest typical error of measurement (expressed as a coefficient of variation percentage [CV%] and as an absolute value in seconds) also occurred between trials 2 and 3, and was 1.0% and 10.9 seconds, respectively. The testing protocol performed on a motorized treadmill in the current study is reproducible in well-trained runners following a single trial, making it a reliable method for monitoring running performance.
A critical appraisal of tools available for monitoring epigenetic changes in clinical samples from patients with myeloid malignancies

Research over the past decade has confirmed that epigenetic alterations act in concert with genetic lesions to deregulate gene expression in acute myeloid leukemia and myelodysplastic syndromes. Epigenetic alterations may serve as markers of disease, and may potentially be used for classification, prognostication and to monitor minimal residual disease. In addition, we now have the capability to pharmaceutically target epigenetic modifications, and there is an urgent need for early validation of the efficacy of the drugs. Also, an improved understanding of the functionality of epigenetic modifications may further pave the road towards individualized therapy. The recent advances in biotechnology and bioinformatics provide a plethora of novel tools for characterizing the epigenome in clinical samples, but at this point the practical, clinical utility of these methodologies needs further exploration. Here, we provide the pros and cons of the currently most feasible methods used for characterizing the methylome in clinical samples, and give a brief introduction to novel approaches to sequencing that may revolutionize our abilities to characterize the genomes and epigenomes in acute myeloid leukemia and myelodysplastic syndrome patients.
Parallel changes in gene expression after 20,000 generations of evolution in Escherichia coli

Twelve populations of Escherichia coli, derived from a common ancestor, evolved in a glucose-limited medium for 20,000 generations. Here we use DNA expression arrays to examine whether gene-expression profiles in two populations evolved in parallel, which would indicate adaptation, and to gain insight into the mechanisms underlying their adaptation. We compared the expression profile of the ancestor to that of clones sampled from both populations after 20,000 generations. The expression of 59 genes had changed significantly in both populations. Remarkably, all 59 were changed in the same direction relative to the ancestor. Many of these genes were members of the cAMP-cAMP receptor protein (CRP) and guanosine tetraphosphate (ppGpp) regulons. Sequencing of several genes controlling the effectors of these regulons found a nonsynonymous mutation in spoT in one population. Moving this mutation into the ancestral background showed that it increased fitness and produced many of the expression changes manifest after 20,000 generations. The same mutation had no effect on fitness when introduced into the other evolved population, indicating that a mutation of similar effect was present already. Our study demonstrates the utility of expression arrays for addressing evolutionary issues including the quantitative measurement of parallel evolution in independent lineages and the identification of beneficial mutations.
Backtracking Optimized DDG Directed Scheduling Algorithm for Clustered VLIW Architectures

This work presents an instruction schedule approach to improve the performance of clustered VLIW architectures. The proposed scheme is based on a preliminary scheduling phase directed though analyzing of Data Dependence Graph (DDG) and a backtracking optimization scheduling phase bringing further improvement by balancing the workloads through clusters and minimizing the penalties of inter-cluster data communications simultaneously. We have implemented and evaluated the proposed scheme with UTDSP benchmarks. Results show a significant speed-up in performance. The speedup can up to 38.58%, with average speedup ranging from 23.91% (2-Clusters) to up to 26.78% (4-Clusters).
AR for the masses: building a low-cost portable AR system from off-the-shelf components

To create the illusion that a virtual object coexists with physical objects and its environment is always an important goal in the research of augmented reality. Though there are already many commercial products on the market, they are too expensive, too cumbersome or too hard to set up for an ordinary user. Our "AR for the masses" system is cheap to build, easy to set up, and it does not require the users to wear a head-mounted display (HMD). Its cost is low because the whole system consists of only two web cameras (for 3D tracking), a paper box (as the proxy object) and a projector which is getting cheaper. It is also easy to set up: we can move the whole system to a new location easily and finish the calibration within just a few minutes.
Implementing and Analyzing a GPU Ray Tracer Kristóf Ralovich

In this paper we discuss the implementation of a GPU ray tracer. Our ray tracer is inspired by Purcell’s recursive GPU ray tracer using regular grid space subdivision and is improved with “proximity cloud” information. This kind of ray tracer implementation is capable of rendering static triangular meshes with dynamic camera and dynamic abstract point light sources. Having presented the implementation and our experiences gained during the implementation process, the performance and scalability of the algorithm are also considered. Scalability is defined in terms of the number of objects in the scene and the resolution of the screen.
Orbital Evolution in Binary and Triple Stars, with an Application to SS Lacertae

We present equations governing the way in which both the orbit and the intrinsic spins of stars in a close binary should evolve subject to a number of perturbing forces, including the effect of a third body in a possibly inclined wider orbit. We illustrate the solutions in some binary star and triple star situations: tidal friction in a wide but eccentric orbit of a radio pulsar about a B star (0045-7319), the Darwin and eccentricity instabilities in a more massive but shorter period massive X-ray binary, and the interaction of tidal friction with Kozai cycles in a triple star, such as β Per at an early stage in that star's life, when all three components were zero-age main sequence stars. We also attempt to model in some detail the interesting triple system SS Lac, which stopped eclipsing in about 1950. We find that our model of SS Lac is quite constrained by the relatively good observational data of this system and leads to a specific inclination (29°) of the outer orbit relative to the inner orbit at epoch zero (1912). We make some predictions about changes to system parameters in the short term (20-40 yr) and also in the medium term (up to ~3000 yr). Although the intrinsic spins of the stars have little effect on the orbit, the converse is not true: the spin axes can vary their orientation relative to the close binary by up to 120° on a timescale of about a century.
Genetic and Epigenetic Regulation of the Brain-Derived Neurotrophic Factor in the Central Nervous System

The BDNF is required for the development and proper function of the central nervous system, where it is involved in a variety of neural and molecular events relevant to cognition, learning, and memory processes. Although only a functional mature protein is synthesized, the human BDNF gene possesses an extensive structural complexity, including the presence of multiple promoters, splicing events, and 3´UTR poly-adenylation sites, resulting in an intricate transcriptional regulation and numerous messengers RNA. Recent data support specific cellular roles of these transcripts. Moreover, a central role of epigenetic modifications on the regulation of BDNF gene transcription is also emerging. The present essay aims to summarize the published information on the matter, emphasizing their possible implications in health and disease or in the treatment of different neurologic and psychiatric disorders.
Two fractions of rough endoplasmic reticulum from rat liver. I. Recovery of rapidly sedimenting endoplasmic reticulum in association with mitochondria

Low-speed centrifugation (640 g) of rat liver homogenates, prepared with a standard ionic medium, yielded a pellet from which a rapidly sedimenting fraction of rough endoplasmic reticulum (RSER) was recovered free of nuclei. This fraction contained 20-25% of cellular RNA and approximately 30% of total glucose-6-phosphatase (ER marker) activity. A major portion of total cytochrome c oxidase (mitochondrial marker) activity was also recovered in this fraction, with the remainder sedimenting between 640 and 6,000 g. Evidence is provided which indicates that RSER may be intimately associated with mitochondria. Complete dissociation of ER from mitochondria in the RSER fraction required very harsh conditions. Sucrose density gradient centrifugation analysis revealed that 95% dissociation could be achieved when the RSER fraction was first resuspended in buffer containing 500 mM KCl and 20 mM EDTA, and subjected to shearing. Excluding KCl, EDTA, or shearing from the procedure resulted in incomplete separation. Both electron microscopy and marker enzyme analysis of mitochondria purified by this procedure indicated that some structural damage and leakage of proteins from matrix and intermembrane compartments had occurred. Nevertheless, when mitochondria from RSER and postnuclear 6,000-g pellet fractions were purified in this way fromanimals injected with [35S]methionine +/- cycloheximide, mitochondria from the postnuclear 6,000-g pellet were found to incorporate approximately two times more cytoplasmically synthesized radioactive protein per milligram mitochondrial protein (or per unit cytochrome c oxidase activity) than did mitochondria from the RSER fraction. Mitochondria-RSER associations, therefore, do not appear to facilitate enhanced incorporation of mitochondrial proteins which are newly synthesized in the cytoplasm.
The Discovery of Quiescent X-Ray Emission from SAX J1808.4–3658, the Transient 2.5 Millisecond Pulsar

We report on a 20 ks BeppoSAX observation of the transient 2.5 ms X-ray pulsar SAX J1808.4-3658 in its quiescent state. A source at a level of ~3 × 10-3 counts s-1 was detected with the BeppoSAX Medium Energy Concentrator Spectrometer at a position consistent with that of SAX J1808.4-3658. The inferred 0.5-10 keV luminosity was ~(2-3) × 1032 ergs s-1 (for a distance of 4 kpc), a value similar to that measured from other quiescent low-mass X-ray transients hosting an old neutron star. This result is discussed in the light of the propeller and radio pulsar shock emission models for the quiescent emission of these systems.
When Resources Collide: Towards a Theory of Coincidence in Information Spaces

This paper is an attempt to lay out foundations for a general theory of coincidence in information spaces such as the World Wide Web, expanding on existing work on bursty structures in document streams and information cascades. We elaborate on the hypothesis that every resource that is published in an information space, enters a temporary interaction with another resource once a unique explicit or implicit reference between the two is found. This thought is motivated by Erwin Shroedingers notion of entanglement between quantum systems. We present a generic information cascade model that exploits only the temporal order of information sharing activities, combined with inherent properties of the shared information resources. The approach was applied to data from the world's largest online citizen science platform Zooniverse and we report about findings of this case study.
Browder's theorems and the spectral mapping theorem

A bounded linear operator T 2 L(X) on a Banach space X is said to satisfy Browder’s theorem if two important spectra, originating from Fredholm theory, the Browder spectrum and the Weyl spectrum, coincide. This expository article also concerns with an approximate point version of Browder’s theorem. A bounded linear operator T 2 L(X) is said to satisfy a-Browder’s theorem if the upper semi-Browder spectrum coincides with the approximate point Weyl spectrum. In this note we give several characterizations of operators satisfying these theorems. Most of these characterizations are obtained by using a localized version of the single-valued extension property of T. This paper also deals with the relationships between Browder’s theorem, a-Browder’s theorem and the spectral mapping theorem for certain parts of the spectrum.
A Rule-Based System for Document Understanding

A rule-based system to make inferences about document images is introduced. Given a digitized document image, the sys tern controls the analysis of the document, and identifies all the different printed regions in the document image. Logical "blocks" of information on the document image are interpreted and classified by this system which then produces as output an editable description of the entire document. The system uses a goal-directed top down approach, and utilizes a three-level rule hierarchy to implement its control strategy.
