Predicting the direction of stock market prices using random forest

Predicting trends in stock market prices has been an area of interest for researchers for many years due to its complex and dynamic nature. Intrinsic volatility in stock market across the globe makes the task of prediction challenging. Forecasting and diffusion modeling, although effective can't be the panacea to the diverse range of problems encountered in prediction, short-term or otherwise. Market risk, strongly correlated with forecasting errors, needs to be minimized to ensure minimal risk in investment. The authors propose to minimize forecasting error by treating the forecasting problem as a classification problem, a popular suite of algorithms in Machine learning. In this paper, we propose a novel way to minimize the risk of investment in stock market by predicting the returns of a stock using a class of powerful machine learning algorithms known as ensemble learning. Some of the technical indicators such as Relative Strength Index (RSI), stochastic oscillator etc are used as inputs to train our model. The learning model used is an ensemble of multiple decision trees. The algorithm is shown to outperform existing algo- rithms found in the literature. Out of Bag (OOB) error estimates have been found to be encouraging. Key Words: Random Forest Classifier, stock price forecasting, Exponential smoothing, feature extraction, OOB error and convergence.
Capacity Expansion Equilibria in Liberalized Electricity Markets: An EPEC Approach

This paper presents a novel way to model the generation capacity expansion problem in a liberalized framework via a multi-year bilevel equilibrium model. In the upper level the competing generation companies maximize their individual profits, while the lower level represents the market using a conjectured-price response approach, which allows us to vary the strategic spot market behavior, to see how much the reigning competitive behavior impacts investment decisions. The bilevel equilibrium model is formulated as an equilibrium problem with equilibrium constraints, transformed into a mixed integer linear program and solved as such using diagonalization in order to verify equilibria. We present a case study to apply this new modeling approach and to demonstrate that the proposed equilibrium problem with equilibrium constraints can have multiple solutions whose respective investments can vary.
The Impact of Educating Parents of Leukemic Children on the Patients’ Quality of Life

Background The quality of life of children with leukemia is reduced by fear and anxiety of parents after diagnosis, lack of information about the disease, treatments, and care of the child. This study aims to evaluate the effect of educating parents of leukemic children on the patients’ quality of life. Methods In this interventional study, sixty parents of ALL children who met inclusion criteria were selected using simple random sampling method, and assigned to the experimental and control groups. The study tool included a valid and reliable questionnaire (TNO-AZL), that was filled in through interview by parents before and two months after the intervention for both groups. The first part of the questionnaire included demographic items and the second part (7 dimensions, each with 8 sections) contained questions related to the quality of life. The scores could range between 56 and 280 and a higher score represented a better quality of life. The intervention included three one-hour classes composed of lecture and question-answer sessions which were held for groups of 4-6 participants, accompanied by a booklet. Results Before the intervention, the quality of life score in the experimental and control groups was 180.83±14.43 and 174.28±20.72, respectively; after the intervention, these figures changed to 226.9±11.76 and 174.41±20.42 respectively. Paired samples T-test proved a significant increase in the quality of life in the experimental group. Conclusion Parent education successfully increased the quality of life of leukemic children; therefore, parental consultation sessions and educational programs are recommended.
Simulation of THz generation and propagation from photo-dember emitters

We demonstrate a simulation of lateral photo-Dember THz emitters in 2D using the drift diffusion equation coupled to a finite differences time domain (FDTD) model with far-field algorithm. We show that the dynamics of the system are more dependent on the currents travelling perpendicular to the semiconductor surface, as opposed to just the lateral currents as previously thought.
Grass MicroRNA Gene Paleohistory Unveils New Insights into Gene Dosage Balance in Subgenome Partitioning after Whole-Genome Duplication[W]

Reconstruction of the grass genome paleohistory revealed subgenome partitioning of microRNA (miRNA) genes during post-whole-genome duplication diploidization. The evolutionary scenario of miRNAs from the ancestral founder pool to the modern complements displayed dosage balance constrictions on the deletion/retention of miRNAs and associated target genes wherein transposable elements may play a major role in miRNA gene synteny disruption. The recent availability of plant genome sequences, combined with a robust evolutionary scenario of the modern monocot and eudicot karyotypes from their diploid ancestors, offers an opportunity to gain insights into microRNA (miRNA) gene paleohistory in plants. Characterization and comparison of miRNAs and associated protein-coding targets in plants allowed us to unravel (1) contrasted genome conservation patterns of miRNAs in monocots and eudicots after whole-genome duplication (WGD), (2) an ancestral miRNA founder pool in the monocot genomes dating back to 100 million years ago, (3) miRNA subgenome dominance during the post-WGD diploidization process with selective miRNA deletion complemented with possible transposable element–mediated return flows, and (4) the miRNA/target interaction-directed differential loss/retention of miRNAs following the gene dosage balance rule. Together, our data suggest that overretained miRNAs in grass genomes may be implicated in connected gene regulations for stress responses, which is essential for plant adaptation and useful for crop variety innovation.
The Fragility of Dissent!: Mediated Resistance at the Gleneagles G8 Summit and the Impact of the 7/7 London Bombings

Informed by ethnographic methods, this article takes a case study approach to the protests of the Dissent! network at the 2005 Gleneagles G8 Summit. Of interest is how activists anticipated, understood and reflexively navigated the 'mediated opportunity' and shifting media dynamics of the G8 Summit. The analysis focuses largely on the representational reverberations of the July 7 th , 2005 London bombings (7/7 bombings) on Dissent! protests. It is argued that the bombings reinforced the fragility and temporality of mediated resistance, and also emphasised the lack of control social movement actors have over mediated spaces of resistance.
[meso-5,10,15,20-Tetrakis(5-bromothiophen-2-yl)porphyrinato-κ4 N,N′,N′′,N′′′]nickel(II)

The NiII atom in the title porphyrin complex, [Ni(C36H16Br4N4S4)], is in a square-planar geometry defined by four pyrrole N atoms. There is considerable buckling in the porphyrin ring with the dihedral angles between the N4 donor set and the pyrrole rings being in the range 17.0 (3)–18.8 (3)°. Each of the six-membered chelate rings is twisted about an Ni—N bond and the dihedral angles between diagonally opposite chelate rings are 13.08 (15) and 13.45 (11)°; each pair of rings is orientated in opposite directions. The bromothienyl rings are twisted out of the plane of the central N4 core with dihedral angles in the range 51.7 (2)–74.65 (19)°. Supramolecular chains along [001] are formed through C—H⋯Br interactions in the crystal packing. Three of the four bromothienyl units are disordered over two coplanar positions of opposite orientation with the major components being in 0.691 (3), 0.738 (3) and 0.929 (9) fractions.
Indications for Orthognathic Surgery - A Review

Background: Orthognathic surgery is a relative common procedure for correcting skeletal malocclusions and deformities. The indications for orthognathic interventions remain, however, controversial. Objective: To conduct a systematic review of studies regarding the indications, logistics, and outcome related to orthognathic surgery. Material and methods: An electronic online search was conducted using PubMed. Key words included “Orthognathic,” “Outcome,” and “Prognosis. ” Additional studies were identified through reference lists of the identified studies. Only studies published from 2000 until November 2015 were included. Results: The search identified 24 publications. All studies evaluated the indications for orthognathic surgery from the patients’ point of view. The included studies showed large variation in study design. No meta-analysis could be performed regarding the indications or outcome. The two most commonly cited indications for orthognathic surgery are functional dental problems and aesthetics considerations. Conclusion: Health is a multidimensional, complex concept that is difficult to evaluate. Every patient must be assessed individually in relation to the indications for orthognathic surgery and their general health. Although, future, more objective guidelines for the indications for orthognathic surgery could be considered, the individual estimates remain the most important parameters in current evaluation.
Mortality in the Sami population of North Norway, 1970—98

Aims: The pattern of mortality among many groups of indigenous people has been shown to be disadvantageous in comparison with the general population. Knowledge regarding causes of death among the Sami population in the northern part of Norway is limited. The Sami constitute an ethnic minority whose lifestyle diverges from that of the rest of the population. Methods: A cohort of 19,801 persons of Sami origin was followed up to evaluate specific causes of mortality during the period 1970—98. Standardized mortality rates (SMR) were calculated using the rural population of the three Norwegian counties included in the study as a reference population. Results: Among Sami, 5,955 total deaths were observed, as opposed to 5,537 expected (SMR=1.08). For both Sami women and men a significantly higher SMR for cerebrovascular diseases was found, which was more pronounced for women. For Sami men, an excess SMR for violent death was observed (SMR 1.32, 95% confidence interval (CI) 1.20—1.46); this was highest among Sami men living in a reindeer-breeding family. For both genders, mortality from all malignant neoplasms combined was lower than in the reference population. SMRs were 0.86 (95% CI 0.79—0.94) and 0.89 (95% CI 0.80—0.99) for men and women, respectively. Low SMRs were also observed for chronic liver diseases, 0.18 (95% CI 0.02—0.63) and 0.12 (95% CI 0.00—0.68) for Sami men and women, respectively. To be a member of a reindeer breeding household appeared to offer protection from mortality caused by circulatory system diseases in men, especially mortality from ischaemic heart disease. Conclusions: The total mortality in the North Norway Sami population, an ethnic minority in Norway, was slightly higher when compared with a regional reference population. The differences observed when evaluating mortality by diagnosis might be due to lifestyle, diet, psychosocial, and/or genetic factors.
Complete nucleotide sequence of a circular plasmid from the Lyme disease spirochete, Borrelia burgdorferi

We have determined the complete nucleotide sequence of a small circular plasmid from the spirochete Borrelia burgdorferi Ip21, the agent of Lyme disease. The plasmid (cp8.3/Ip21) is 8,303 bp long, has a 76.6% A+T content, and is unstable upon passage of cells in vitro. An analysis of the sequence revealed the presence of two nearly perfect copies of a 184-bp inverted repeat sequence separated by 2,675 bp containing three closely spaced, but nonoverlapping, open reading frames (ORFs). Each inverted repeat ends in sequences that may function as signals for the initiation of transcription and translation of flanking plasmid sequences. A unique oligonucleotide probe based on the repeated sequence showed that the DNA between the repeats is present predominantly in a single orientation. Additional copies of the repeat were not detected elsewhere in the Ip21 genome. An analysis for potential ORFs indicates that the plasmid has nine highly probable protein-coding ORFs and one that is less probable; together, they occupy almost 71% of the nucleotide sequence. Analysis of the deduced amino acid sequences of the ORFs revealed one (ORF-9) with features in common with Borrelia lipoproteins and another (ORF-2) having limited homology with a replication protein, RepC, from a gram-positive plasmid that replicates by a rolling circle (RC) mechanism. Known collectively as RC plasmids, such plasmids require a double-stranded origin at which the Rep protein nicks the DNA to generate a single-stranded replication intermediate. cp8.3/Ip21 has three copies of the heptameric motif characteristically found at a nick site of most RC plasmids. These observations suggest that cp8.3/Ip21 may replicate by an RC mechanism.
Detecting Communities under Differential Privacy

Complex networks usually expose community structure with groups of nodes sharing many links with the other nodes in the same group and relatively few with the nodes of the rest. This feature captures valuable information about the organization and even the evolution of the network. Over the last decade, a great number of algorithms for community detection have been proposed to deal with the increasingly complex networks. However, the problem of doing this in a private manner is rarely considered. In this paper, we solve this problem under differential privacy, a prominent privacy concept for releasing private data. We analyze the major challenges behind the problem and propose several schemes to tackle them from two perspectives: input perturbation and algorithm perturbation. We choose Louvain method as the back-end community detection for input perturbation schemes and propose the method LouvainDP which runs Louvain algorithm on a noisy super-graph. For algorithm perturbation, we design ModDivisive using exponential mechanism with the modularity as the score. We have thoroughly evaluated our techniques on real graphs of different sizes and verified that ModDivisive steadily gives the best modularity and avg.F1Score on large graphs while LouvainDP outperforms the remaining input perturbation competitors in certain settings.
Accelerated Weightbearing Rehabilitation After Matrix-Induced Autologous Chondrocyte Implantation in the Tibiofemoral Joint

Background: Matrix-induced autologous chondrocyte implantation (MACI) has become an established technique for the repair of full-thickness chondral defects in the knee, although best patient outcomes appear limited by a lack of evidence-based knowledge on how to progressively increase postoperative weightbearing (WB) and rehabilitation exercises. Hypothesis: To determine the safety and efficacy of an accelerated WB regimen after MACI in the tibiofemoral joint. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Clinical and radiological assessments were performed in 28 knees at 12 months after MACI to the medial or lateral femoral condyle. Both rehabilitation interventions sought to protect the implant for an initial period and then incrementally increase load bearing. Under the “accelerated” (AR) protocol, patients reached full WB at 6 weeks after surgery compared with 8 weeks for what was considered to be the current “best practice” (CR) WB regimen based on previous research. Assessments included the Knee Injury and Osteoarthritis Outcome Score (KOOS), 36-Item Short Form Health Survey (SF-36), visual analog scale, 6-minute walk test, and active knee range of motion (ROM). High-resolution magnetic resonance imaging (MRI) was used to describe the quality and quantity of repair tissue via the assessment of pertinent parameters of graft repair as well as an MRI composite score. Results: Patients in both groups demonstrated significant improvement (P < .05) in all clinical measures over the preoperative and postoperative timeline from before surgery to 12 months after surgery. The AR group reported significantly better (P < .05) SF-36 physical component scores at 8 weeks and significantly greater (P < .05) KOOS quality of life scores at 6 and 12 months postoperatively. Although no differences (P > .05) were observed between the 2 groups for active knee ROM, the AR group did achieve full active knee extension as early as 4 weeks compared with the CR group at 12 weeks. There was no difference (P > .05) in graft quality as assessed by MRI (MOCART composite score: AR, 3.34; CR, 3.04), with no patients suffering any adverse effects from the implant up to 12 months, regardless of the rehabilitation protocol employed. Conclusion: The AR approach that reduced the length of time spent ambulating on crutches resulted in improved general physical function and quality of life and an earlier attainment of full active knee extension when compared with the CR approach. There were no graft complications ascertained through MRI. This regimen appears safe and may potentially speed up the recovery of normal gait function. A larger patient cohort and follow-up are required to observe long-term graft outcomes.
Reference Groups and Product Line Decisions: An Experimental Investigation of Limited Editions and Product Proliferation

Some luxury goods manufacturers offer limited editions of their products, whereas some others market multiple product lines. Researchers have found that reference groups shape consumer evaluations of these product categories. Yet little empirical research has examined how reference groups affect the product line decisions of firms. Indeed, in a field setting it is quite a challenge to isolate reference group effects from contextual effects and correlated effects. In this paper, we propose a parsimonious model that allows us to study how reference groups influence firm behavior and that lends itself to experimental analysis. With the aid of the model, we investigate the behavior of consumers in a laboratory setting where we can focus on the reference group effects after controlling for the contextual and correlated effects. The experimental results show that in the presence of strong reference group effects, limited editions and multiple products can help improve firms' profits. Furthermore, the trends in the purchase decisions of our participants point to the possibility that they are capable of introspecting close to two steps of thinking at the outset of the game and then learning through reinforcement mechanisms.
Optogenetics: potentials for addiction research

Research on the biology of addiction has advanced significantly over the last 50 years expanding our understanding of the brain mechanisms underlying reward, reinforcement and craving. Novel experimental approaches and techniques have provided an ever increasing armory of tools to dissect behavioral processes, neural networks and molecular mechanisms. The ultimate goal is to reintegrate this knowledge into a coherent, mechanistic framework of addiction to help identify new treatment. This can be greatly facilitated by using tools that allow, with great spatial and temporal specificity, to link molecular changes with altered activation of neural circuits and behavior. Such specificity can now be achieved by using optogenetic tools. Our review describes the general principles of optogenetics and its use to understand the links between neural activity and behavior. We also provide an overview of recent studies using optogenetic tools in addiction and consider some outstanding questions of addiction research that are particularly amenable for optogenetic approaches.

Microfinance and women entrepreneurs in Pakistan

Purpose – The purpose of this paper is to outline findings of an initial exploratory study, undertaken as part of a larger ongoing research project, seeking to understand the influence and impact of microfinance on women's entrepreneurship and empowerment within developing countries such as Pakistan.Design/methodology/approach – The research conducted in this study used 37 semi‐structured questionnaires from women borrowers financed by two microfinance institutions of Pakistan.Findings – The findings show that microfinance institution is providing credit to women for starting their business. However, 62 percent of the women borrowers established their own business from microfinance loan and other 38 percent did not use microfinance for the said purpose. The lack of training by microfinance institutions is also considered to be a factor in very less number of women starting new business from microfinance loan.Research limitations/implications – A small sample is used from the Punjab province of Pakistan, t.
Syntactic definiteness in the grammar of Modern Hebrew

Definiteness has often been assumed to play a role in syntax, most notably in relation to various definiteness effects and case alternations (Belletti 1988; De Hoop 1992; and many others). The question whether this involves a semantic property that is relevant in syntax, or an independent syntactic representation of definiteness, remains to a large extent unanswered. This paper shows that, on the one hand, Hebrew provides independent evidence for assuming a definiteness feature in syntax, and on the other hand, this formal definiteness does not simply correlate with semantic definiteness, and there is no simple one-to-one mapping between the two kinds of definiteness. The second part of this paper focuses on the Hebrew object marker et, which appears only in front of DPs having the syntactic definiteness feature. I argue that et' fulfills a requirement for structural case that Hebrew verbs cannot assign, and that this requirement is related to the representation of definiteness as a formal feature and not to any semantic property. In this light I consider Belletti's (1988) theory of abstract partitive and show that Hebrew object marking seems to provide evidence against it.
A DOUBLE-BLIND STUDY OF IDU IN HUMAN HERPES SIMPLEX KERATITIS.

Since the introduction of 5-iodo-2'-deoxyuridine (IDU) by Kaufman 1 as a treatment for herpes simplex keratitis, there has been a great arousal of interest in antiviral chemotherapy. Effectiveness of this drug was first demonstrated in controlled studies of the eyes of rabbits 2,3 and has been confirmed in a controlled laboratory study at another institution. 4 Following the initial reports of the controlled laboratory studies, there have been a number of clinical reports describing a universally beneficial effect of this drug in human herpetic disease, in series ranging in size from two to five hundred patients. 5-12 All of these reports have been uncontrolled and thereby have overlooked two basic facts about human herpes simplex keratitis, that it is a self-limited disease, and that, with the exception of the rarely recognized primary infection, it is a recurrent infection which develops in the presence of adequate antibody level, not the same
