On the Faithfulness of Simulated Student Performance Data

The validation of models for skills assessment is often conducted by using simulated students because their skills mastery can be predefined. Student performance data is generated according to the predefined skills and models are trained over this data. The accuracy of model skill predictions can thereafter be verified by comparing the predefined skills with the predicted ones. We investigate the faithfulness of different methods for generating simulated data by comparing the predictive performance of a Bayesian student model over real vs. simulated data for which the parameters are set to reflect those of the real data as closely as possible. A similar performance suggests that the simulated data is more faithful to the real data than for a dissimilar performace. The results of our simulations show that the latent trait model (IRT) is a relatively good candidate to simulate student performance data, and that simple methods that solely replicate mean and standard deviation distributions can fail drastically to reflect the characteristics of real data.
Paraphrase Recognition using Neural Network Classification

Paraphrasing refers to conveying the same content in several ways. The successful recognition of paraphrases is crucial to various natural language processing tasks such as Information Extraction, Document Summarization, Question Answering etc. Several techniques have been employed for paraphrase recognition using lexical, syntactic and semantic features. Many of these systems have been tested on the MicroSoft Research Paraphrase Corpus. But the performance of these systems has scope for further improvement. Since neural network architectures model the human brain structure which excels at natural language processing tasks, this paper presents a neural network classifier for recognizing paraphrases. A combination of lexical, syntactic and semantic features has been used to train a Back Propagation network. The system can be utilized for detecting similar sentences in applications such as Question Answering and detection of plagiarized content.
Proteoglycan 4: A dynamic regulator of skeletogenesis and parathyroid hormone skeletal anabolism

Proteoglycan 4 (Prg4), known for its lubricating and protective actions in joints, is a strong candidate regulator of skeletal homeostasis and parathyroid hormone (PTH) anabolism. Prg4 is a PTH‐responsive gene in bone and liver. Prg4 null mutant mice were used to investigate the impact of proteoglycan 4 on skeletal development, remodeling, and PTH anabolic actions. Young Prg4 mutant and wild‐type mice were administered intermittent PTH(1–34) or vehicle daily from 4 to 21 days. Young Prg4 mutant mice had decreased growth plate hypertrophic zones, trabecular bone, and serum bone formation markers versus wild‐type mice, but responded with a similar anabolic response to PTH. Adult Prg4 mutant and wild‐type mice were administered intermittent PTH(1–34) or vehicle daily from 16 to 22 weeks. Adult Prg4 mutant mice had decreased trabecular and cortical bone, and blunted PTH‐mediated increases in bone mass. Joint range of motion and animal mobility were lower in adult Prg4 mutant versus wild‐type mice. Adult Prg4 mutant mice had decreased marrow and liver fibroblast growth factor 2 (FGF‐2) mRNA and reduced serum FGF‐2, which were normalized by PTH. A single dose of PTH decreased the PTH/PTHrP receptor (PPR), and increased Prg4 and FGF‐2 to a similar extent in liver and bone. Proteoglycan 4 supports endochondral bone formation and the attainment of peak trabecular bone mass, and appears to support skeletal homeostasis indirectly by protecting joint function. Bone‐ and liver‐derived FGF‐2 likely regulate proteoglycan 4 actions supporting trabeculae formation. Blunted PTH anabolic responses in adult Prg4 mutant mice are associated with altered biomechanical impact secondary to joint failure. © 2012 American Society for Bone and Mineral Research

Backpropagation of Physiological Spike Trains in Neocortical Pyramidal Neurons: Implications for Temporal Coding in Dendrites

In vivo neocortical neurons fire apparently random trains of action potentials in response to sensory stimuli. Does this randomness represent a signal or noise around a mean firing rate? Here we use the timing of action potential trains recorded in vivo to explore the dendritic consequences of physiological patterns of action potential firing in neocortical pyramidal neuronsin vitro. We find that action potentials evoked by physiological patterns of firing backpropagate threefold to fourfold more effectively into the distal apical dendrites (>600 μm from the soma) than action potential trains reflecting their mean firing rate. This amplification of backpropagation was maximal during high-frequency components of physiological spike trains (80–300 Hz). The disparity between backpropagation during physiological and mean firing patterns was dramatically reduced by dendritic hyperpolarization. Consistent with this voltage dependence, dendritic depolarization amplified single action potentials by fourfold to sevenfold, with a spatial profile strikingly similar to the amplification of physiological spike trains. Local blockade of distal dendritic sodium channels substantially reduced amplification of physiological spike trains, but did not significantly alter action potential trains reflecting their mean firing rate. Dendritic electrogenesis during physiological spike trains was also reduced by the blockade of calcium channels. We conclude that amplification of backpropagating action potentials during physiological spike trains is mediated by frequency-dependent supralinear temporal summation, generated by the recruitment of distal dendritic sodium and calcium channels. Together these data indicate that the temporal nature of physiological patterns of action potential firing contains a signal that is transmitted effectively throughout the dendritic tree.
Detection of Mycobacterium tuberculosis by Using Loop-Mediated Isothermal Amplification Combined with a Lateral Flow Dipstick in Clinical Samples

Tuberculosis (TB) is a communicable disease caused by the bacterium Mycobacterium tuberculosis (MTB) and is a persistent problem in the developing countries. Loop-mediated isothermal amplification (LAMP) allows DNA to be amplified rapidly at a constant temperature. Here, a LAMP method was combined with a chromatographic lateral-flow dipstick (LFD) to detect IS6110 gene of M. tuberculosis specifically and rapidly. The reaction was optimized at 63°C for 60 min, and the amplified DNA hybridized to an FITC-labeled oligonucleotide probe for 5 min was detected at the LFD test line 5 min after application. Excluding the step of DNA extraction, the test results could be generated approximately within 1 h. In addition to the advantage of short assay time, this technique could avoid the contact of carcinogenic ethidium bromide due to the exclusion of the electrophoresis analysis step. Furthermore, the data indicated that LAMP-LFD could detect M. tuberculosis genomic DNA as little as 5 pg. The technique showed a significant specificity since no cross-hybridization to M. intracellulare (MIC), M. fortuitum (MFT), M. avium (MAV), M. kansasii (MKS), and M. gordonae (MGD) genomic DNAs was observed. In the clinical unknown samples test, the sensitivity of LAMP-LFD was 98.92 % and the specificity was 100 % compared to those of the standard culture assay. Based on its sensitivity, specificity, rapidity, low cost, and convenience, LAMP-LFD could be applicable for use in both laboratories and epidemiological surveys of MTB.
The family and demography in contemporary Taiwan.

This paper analyzes changes in the family [in] Taiwan in the context of demographic change and ideological characteristics. The analysis is mainly based on a series of KAP surveys from 1965 to 1985 which interviewed representative samples of the households with married women of ages 20-39 in Taiwan. The results indicate that although the traditional Chinese family system persists it is being eroded by the rapid social and demographic changes. Following the resolution of extended families the proportions of nuclear family increased significantly and the size of family reduced. Although most women eventually get married the age at marriage increased and the divorce rate also increased. The family structure varies significantly by region and traditional beliefs.

Upper Limb Immobilisation: A Neural Plasticity Model with Relevance to Poststroke Motor Rehabilitation

Advances in our understanding of the neural plasticity that occurs after hemiparetic stroke have contributed to the formulation of theories of poststroke motor recovery. These theories, in turn, have underpinned contemporary motor rehabilitation strategies for treating motor deficits after stroke, such as upper limb hemiparesis. However, a relative drawback has been that, in general, these strategies are most compatible with the recovery profiles of relatively high-functioning stroke survivors and therefore do not easily translate into benefit to those individuals sustaining low-functioning upper limb hemiparesis, who otherwise have poorer residual function. For these individuals, alternative motor rehabilitation strategies are currently needed. In this paper, we will review upper limb immobilisation studies that have been conducted with healthy adult humans and animals. Then, we will discuss how the findings from these studies could inspire the creation of a neural plasticity model that is likely to be of particular relevance to the context of motor rehabilitation after stroke. For instance, as will be elaborated, such model could contribute to the development of alternative motor rehabilitation strategies for treating poststroke upper limb hemiparesis. The implications of the findings from those immobilisation studies for contemporary motor rehabilitation strategies will also be discussed and perspectives for future research in this arena will be provided as well.
Tooth loss and osteoporosis: the OSTEODENT Study.

AIM To determine the cross-sectional association of the osteoporotic status of patients with the number of their teeth, with and without taking into account age and/or smoking. MATERIAL & METHODS At four centres, the study recruited 665 females aged 45-70 years and the number of teeth was counted for 651 subjects. Bone density was measured at the total hip, femoral neck and lumbar spine. RESULTS The mean number of teeth in the osteoporotic subjects was 3.3 fewer than normal subjects and 2.1 fewer if those with no teeth were excluded. The association between osteoporosis and having <6 or having <28 teeth remained significant after adjusting for age, smoking and centre with p-values of 0.016 and 0.011, respectively. A single regression model for tooth count with normal errors would not fit all the data. By fitting mixture regression models to subjects with tooth count >0, three clusters were identified corresponding to different degrees of tooth loss. The overall effect of osteoporosis was as follows: -1.8 teeth before and after adjusting for smoking, -1.2 teeth after adjusting for age, and -1.1 teeth after adjusting for both age and smoking. CONCLUSIONS We have established a significant association between osteoporosis and tooth loss after adjusting the effect for age and smoking.
Deterrence and Compellence: A Critical Assessment of Conventional Wisdom

Although the theory of deterrence is widely accepted, many of the important propositions derived from the general argument have yet to be tested against the record of interstate conflict. The research reported here tests four propositions that relate to hypothesized differences between deterrence and compellence. Based on the results from an analysis of 135 international conflicts, I conclude that conventional wisdom regarding these assumed differences is faulty in some significant respects. Specifically, I find that deterrence of immediate threats is usually no ‘easier’ than compellence, and that compellence is not ‘reckless’ behavior in the sense that rash decisions are made.
Financial distress and its predicting factors among iranian cancer patients.

BACKGROUND Financial distress due to the cost of cancer treatments is prevalent among cancer patients. Identifying the level of financial distress and its affecting factors has an important role in providing supportive services. Accordingly, the aims of this study were to determine these parameters among Iranian cancer patients. MATERIALS AND METHODS This descriptive-correlational study was undertaken among 262 cancer patients admitted to both private and public hospitals in East Azerbaijan province, Iran. The financial distress/financial well being scale was used to determine financial distress. The data were analyzed using SPSS software using descriptive and inferential statistics (multiple linear regression). RESULTS Among the 262 cancer patients, 57.3% were male and their mean age was 47.0 years. The mean score for financial distress was 4.12 (2.01). The final regression model demonstrated that the independent variables (predictors) of income less than living expenses, income equal to living expenses, having an employed spouse in governmental job and living with parents, with regression coefficients of -1.029, -0.515, 0.198, and 0.096, respectively, were predictors of financial distress among cancer patients. These variables accounted for 50% of changes in variance of financial distress. CONCLUSIONS Iranian cancer patients have moderate to high levels of financial distress. Considering policies for managing direct and indirect costs of cancer treatments must be followed.
Understanding ageing in sub-Saharan Africa: exploring the contributions of religious and secular social involvement to life satisfaction

ABSTRACT Rapid urbanisation in sub-Saharan Africa is believed to have weakened the traditional family ties which sustained older people in the past, but there is little empirical evidence about how older people today perceive their ageing experience in sub-Saharan Africa. The international gerontology literature demonstrates that, apart from financial wellbeing and health status, religious and secular forms of social involvement are key predictors of life satisfaction in older ages. No formal analysis, however, exists on the effects of religious and non-religious social involvement on the subjective wellbeing of older people in sub-Saharan nations. This study sought to fill this gap by examining the relationship between religious identity, religiosity, and secular social engagement using survey data from a sample of 2,524 men and women aged 50 or more years living in informal settlements of Nairobi City. We found significant differences in life satisfaction between Moslems, Catholics and non-Catholic Christians. Secular social support, personal sociability and community participation had positive effects on subjective wellbeing. In this context, we also observed that next to health status, the social involvement of older people was very important for life satisfaction.
Rehydrated Lyophilized Rifampicin-Loaded mPEG–DSPE Formulations for Nebulization

Rifampicin-loaded nanoparticles were prepared using two different molecular weights of poly-(ethylene oxide)-block-distearoyl phosphatidyl-ethanolamine (mPEG2000–DSPE and mPEG5000–DSPE) polymers. Particle sizes of all formulations studied were in the range of 162–395 nm. The entrapment efficiency (EE) was not affected by the copolymer’s molecular weight, and the highest EE (100%) was obtained with drug to copolymer ratio of 1:5. The differential scanning calorimetry (DSC) thermograms showed Tg of rifampicin-loaded PEG–DSPE nanoparticles that shifted to a lower value, indicating entrapment of rifampicin in polymer matrix. The Fourier transformed infrared spectra revealed no chemical interactions between the drug and both copolymers. The in vitro drug release from the formulations occurred over 3 days and followed first-order release kinetic and Higuchi diffusion model. The nebulization of rehydrated lyophilized rifampicin mPEG–DSPE formulations had mass median aerodynamic diameter of 2.6 µm and fine particle fraction of 42%. The aerodynamic characteristic of the preparations was not influenced by the molecular weight of the copolymers. Therefore, it is suggested that both mPEG–DSPE are promising candidates as rifampicin carrier for pulmonary delivery.
Distributed Representation for Traditional Chinese Medicine Herb via Deep Learning Models

Traditional Chinese Medicine (TCM) has accumulated a big amount of precious resource in the long history of development. TCM prescriptions that consist of TCM herbs are an important form of TCM treatment, which are similar to natural language documents, but in a weakly ordered fashion. Directly adapting language modeling style methods to learn the embeddings of the herbs can be problematic as the herbs are not strictly in order, the herbs in the front of the prescription can be connected to the very last ones. In this paper, we propose to represent TCM herbs with distributed representations via Prescription Level Language Modeling (PLLM). In one of our experiments, the correlation between our calculated similarity between medicines and the judgment of professionals achieves a Spearman score of 55.35 indicating a strong correlation, which surpasses human beginners (TCM related field bachelor student) by a big margin (over 10%).
Strengths and Weaknesses of Quantum Computing

Recently a great deal of attention has been focused on quantum computation following a sequence of results [Bernstein and Vazirani, in Proc. 25th Annual ACM Symposium Theory Comput. , 1993, pp. 11--20, SIAM J. Comput. , 26 (1997), pp. 1277--1339], [Simon, in Proc. 35th Annual IEEE Symposium Foundations Comput. Sci., 1994, pp. 116--123, SIAM J. Comput. , 26 (1997), pp. 1340--1349], [Shor, in Proc. 35th Annual IEEE Symposium Foundations Comput. Sci., 1994, pp. 124--134] suggesting that quantum computers are more powerful than classical probabilistic computers. Following Shor's result that factoring and the extraction of discrete logarithms are both solvable in quantum polynomial time, it is natural to ask whether all of $\NP$ can be efficiently solved in quantum polynomial time. In this paper, we address this question by proving that relative to an oracle chosen uniformly at random with probability 1 the class $\NP$ cannot be solved on a quantum Turing machine (QTM) in time $o(2^{n/2})$. We also show that relative to a permutation oracle chosen uniformly at random with probability 1 the class $\NP \cap \coNP$ cannot be solved on a QTM in time $o(2^{n/3})$. The former bound is tight since recent work of Grover [in {\it Proc.\ $28$th Annual ACM Symposium Theory Comput. }, 1996] shows how to accept the class $\NP$ relative to any oracle on a quantum computer in time $O(2^{n/2})$.
A channel estimation algorithm for MIMO-SCFDE

This letter proposes a novel method for channel estimation in a single-carrier multiple input-multiple output (MIMO) system with frequency-domain equalization/detection. To this end, we construct novel short MIMO training sequences that have constant envelope in the time domain to preclude the peak-to-average power ratio problem encountered in many systems that utilize the frequency domain for data recovery. Simultaneously, the spectrum in the frequency domain is flat except for a grid of nulls for predefined frequency tones. Armed with these sequences, we provide an algorithm that is optimal in the least squares (LS) sense at a potentially low computational cost. Results show that the algorithm performs identically to other proposed LS techniques. Furthermore, the algorithm is extremely bandwidth efficient in that the total training overhead required to obtain full CSI is just one block.
Aperture corrections for disk galaxy properties derived from the CALIFA survey - Balmer emission lines in spiral galaxies

This work investigates the effect of the aperture size on derived galaxy properties for which we H alpha ve spatially-resolved optical spectra. We focus on some indicators of star formation activity and dust attenuation for spiral galaxies that have been widely used in previous work on galaxy evolution. We investigated 104 spiral galaxies from the CALIFA survey for which 2D spectroscopy with complete spatial coverage is available. From the 3D cubes we derived growth curves of the most conspicuous Balmer emission lines (H alpha, H beta) for circular apertures of different radii centered at the galaxy's nucleus after removing the underlying stellar continuum. We find that the H alpha flux (f(H alpha)) growth curve follows a well-defined sequence with aperture radius that shows a low dispersion around the median value. From this analysis, we derived aperture corrections for galaxies in different magnitude and redshift intervals. Once stellar absorption is properly accounted for, the f (H alpha)/f(H beta) ratio growth curve shows a smooth decline, pointing toward the absence of differential dust attenuation as a function of radius. Aperture corrections as a function of the radius are provided in the interval [0.3, 2.5]R-50. Finally, the H alpha equivalent-width (EW(H alpha)) growth curve increases with the size of the aperture and shows a very high dispersion for small apertures. This prevents us from using reliable aperture corrections for this quantity. In addition, this result suggests that separating star-forming and quiescent galaxies based on observed EW(H alpha) through small apertures will probably result in low EW(H alpha) star-forming galaxies begin classified as quiescent.
