Is there something I'm missing? Topic Modeling in eDiscovery

In legal eDiscovery, the parties are required to search through their electronically stored information to find documents that are relevant to a specific case. Negotiations over the scope of these searches are often based on a fear that something will be missed. This paper continues an argument that discovery should be based on identifying the facts of a case. If a search process is less than complete (if it has Recall less than 100%), it may still be complete in presenting all of the relevant available topics. In this study, Latent Dirichlet Allocation was used to identify 100 topics from all of the known relevant documents. The documents were then categorized to about 80% Recall (i.e., 80% of the relevant documents were found by the categorizer, designated the hit set and 20% were missed, designated the missed set). Despite the fact that less than all of the relevant documents were identified by the categorizer, the documents that were identified contained all of the topics derived from the full set of documents. This same pattern held whether the categorizer was a na\"ive Bayes categorizer trained on a random selection of documents or a Support Vector Machine trained with Continuous Active Learning (which focuses evaluation on the most-likely-to-be-relevant documents). No topics were identified in either categorizer's missed set that were not already seen in the hit set. Not only is a computer-assisted search process reasonable (as required by the Federal Rules of Civil Procedure), it is also complete when measured by topics.

In laboratory experiments bidding in first-price auctions is more aggressive than predicted by the risk-neutral Bayesian Nash Equilibrium (RNBNE) a finding known as the overbidding puzzle. Several models have been proposed to explain the overbidding puzzle, but no canonical alternative to RNBNE has emerged, and RNBNE remains the basis of the structural auction literature. Instead of estimating a particular model of overbidding, we use the overbidding restriction itself for identification, which allows us to bound the valuation distribution, the seller’s payoff function, and the optimal reserve price. These bounds are consistent with RNBNE and all models of overbidding and remain valid if different bidders employ different bidding strategies. We propose simple estimators and evaluate the validity of the bounds numerically and in experimental data. JEL Codes: C57, D44, C14
Multiple Quantum Spin Liquid Phases in 1T-TaS2

Quantum materials exhibiting magnetic frustration are strongly connected to diverse exotic physical phenomena, including high-Tc superconductivity, topological order and quantum spin liquids (QSLs). A particular feature of a QSL is that magnetic order is destabilized by quantum fluctuations of the spins, yielding a quantum-entangled fluidlike state of matter, which is a quantum phase characterized by fractionalized spinon excitations. Previous experiments on QSLs have usually been interpreted in terms of a single quantum phase, although theory indicates that many distinct quantum phases with similar energies are competing in typical frustrated spin models. Here we report experimental evidence for several competing quantum phases in a triangular-lattice QSL, obtained by combining temperature-dependent muon spin relaxation and specific heat measurements on 1T-TaS2 crystals. The results may be explained by three distinct underlying Z2 QSL phases that determine the properties as temperature is reduced. The accompanying spinon density of states versus energy for these phases switches from constant to linear and back again to constant.
Impact ionization and multiple photon absorption in the two-dimensional photoexcited Hubbard model

We study the non-equilibrium response of a 4x3 Hubbard model at U=8 under the influence of a short electric field pulse, with the main focus on multiple photon excitations and on the change of double occupancy after the pulse. The behavior mainly depends on the driving frequency of the electric field. The largest change of double occupancy occurs during the pulse. For frequencies below the Mott gap, we observe multiphoton excitations at large field intensities. For frequencies beyond the gap energy, there is a region where Auger recombination reduces the double occupancy after the pulse. Impact ionization (Multi Exciton Generation), namely a growing double occupancy after the pulse, occurs for frequencies larger than twice the Mott gap. From the Loschmidt amplitude we compute the eigenstate spectrum of the quantum state after the pulse, observing multiple distinct photon excitation peaks, in line with expectations from a quasiparticle picture. We introduce a technique with which we analyze the time evolution of double occupancy in each peak individually. The long-term behavior of the double occupancy almost only depends on the absorbed energy, and we explore the connection of this property to the Eigenstate Thermalization Hypothesis.
The Accentuation Bias: Money Literally Looms Larger (and Sometimes Smaller) to the Powerless

The present research explores how people's place in a power hierarchy alters their representations of valued objects. The authors hypothesized that powerlessness produces an accentuation bias by altering the physical representation of monetary objects in a manner consistent with the size-to-value relationship. In the first three experiments, powerless participants, induced through episodic priming or role manipulations, systematically overestimated the size of objects associated with monetary value (i.e., quarters, poker chips) compared to powerful and baseline participants. However, when value was inversely associated with size (i.e., smaller objects were more valuable), the powerless drew these valued objects smaller, not larger. In addition, the accentuation bias by the powerless was more pronounced when the monetary value associated with the object was greater, increased when the object was physically present, and was mediated by differences in subjective value. These findings suggest that powerlessness fosters compensatory processes that guide representations of valued objects.
Mutational analysis of a yeast transcriptional terminator

Abstract We have isolated and mutagenized a DNA fragment from Saccharomyces cerevisiae that specifies mRNA 3' end formation for the convergently transcribed CYC1 and UTR1 genes. An in vivo plasmid supercoiling assay previously showed that this fragment is a transcriptional terminator, and "run-on" assays shown here are consistent with this interpretation. The poly(A) sites in the mRNAs formed by the fragment are the same whether the fragment resides at the native location or at a heterologous location. No single linker substitution abolishes the fragment's activity, whereas certain large, nonoverlapping deletions have strong, deleterious effects. Therefore, the yeast terminator behaves more like rho-dependent bacterial terminators than terminators of higher eukaryotes. That a number of deletions or substitutions have different effects in the two orientations suggests that the fragment contains the sequences of two, unidirectional terminator elements.
Enhanced data clustering and classification using auto-associative neural networks and self organizing maps

This thesis presents a number of investigations leading to introduction of novel applications of intelligent algorithms in the fields of informatics and analytics. This research aims to develop novel methodologies to reduce dimensions and clustering of highly non-linear multidimensional data. Improving the performance of existing methodologies has been based on two fundamental approaches. The first is to look into making novel structural re-arrangements by hybridisation of conventional intelligent algorithms which are Auto-Associative Neural Networks (AANN) and Self Organizing Maps (SOM) for data clustering improvement. The second is to enhance data clustering and classification performance by introducing novel fundamental algorithmic changes known as M3-SOM in the data processing and training procedure of conventional SOM. Both approaches are tested, benchmarked and analysed using three datasets which are Iris Flowers, Italian Olive Oils and Wine through case studies for dimension reduction, clustering and classification of complex and non-linear data. The study on AANN alone shows that this non-linear algorithm is able to efficiently reduce dimensions of the three datasets. This paves the way towards structurally hybridising AANN as dimension reduction method with SOM as clustering method (AANNSOM) for data clustering enhancement. This hybrid AANNSOM is then introduced and applied to cluster Iris Flowers, Italian Olive Oils and Wine datasets. The hybrid methodology proves to be able to improve data clustering accuracy, reduce quantisation errors and decrease computational time when compared to SOM in all case studies. However, the topographic errors showed inconsistency throughout the studies and it is still difficult for both AANNSOM and SOM to provide additional inherent information of the datasets such as the exact position of a data in a cluster. Therefore, M3-SOM, a novel methodology based on SOM training algorithm is proposed, developed and studied on the same datasets. M3-SOM was able to improve data clustering and classification accuracy for all three case studies when compared to conventional SOM. It is also able to obtain inherent information about the position of one data or "sub-cluster" towards other data or sub-cluster within the same class in Iris Flowers and Wine datasets. Nevertheless, it faces difficulties in achieving the same level of performance when clustering Italian Olive Oils data due to high number of data classes. However, it can be concluded that both methodologies have been able to improve data clustering and classification performance as well as to discover inherent information inside multidimensional data.
SiC trench MOSFET with integrated side-wall Schottky barrier diode having P+ electric field shield

A new SiC trench MOSFET (T-MOSFET) integrated with a side-wall Schottky Barrier Diode (SBD) to form a compact power device is proposed. The proposed structure applies two trenches to form the n-channel and SBD in a single cell, respectively. A P+ is implanted after etching the trenches to form a shield for both the gate oxide and the Schottky barrier. The breakdown voltage of the proposed one is about 363% larger than that of the conventional trench MOSFET (CT-MOSFET) with integrated SBD. The integrated SBD of the proposed T-MOSFET exhibits an ultra-low leakage current (1 μA/cm2) and low forward voltage drop (Von_diode ≈ 0.9V), as well as low reverse recovery charge (Qrr = 0.73 μC/cm2).
Decoding of Executed Movements and Source Imaging

A brain-computer interface (BCI) in combination with a neuroprosthesis can be used to restore movement in paralyzed persons. Usually, the control of such BCIs by the deliberate modulation of brain oscillations is unnatural and unintuitive. Recently, low-frequency brain signals have been found to encode movement information and can be used to decode movement trajectories. These signals are potential candidates for new types of BCIs which can be used to naturally control neuroprosthesis by imagining movement trajectories. We analyzed the contributing brain areas in the source space and found motor areas but also parietal and lateral areas encoding movement information.
Integrin α1β1 Controls Reactive Oxygen Species Synthesis by Negatively Regulating Epidermal Growth Factor Receptor-Mediated Rac Activation

ABSTRACT Integrins control many cell functions, including generation of reactive oxygen species (ROS) and regulation of collagen synthesis. Mesangial cells, found in the glomerulus of the kidney, are able to produce large amounts of ROS via the NADPH oxidase. We previously demonstrated that integrin α1-null mice develop worse fibrosis than wild-type mice following glomerular injury and this is due, in part, to excessive ROS production by α1-null mesangial cells. In the present studies, we describe the mechanism whereby integrin α1-null mesangial cells produce excessive ROS. Integrin α1-null mesangial cells have constitutively increased basal levels of activated Rac1, which result in its increased translocation to the cell membrane, excessive ROS production, and consequent collagen IV deposition. Basal Rac1 activation is a direct consequence of ligand-independent increased epidermal growth factor receptor (EGFR) phosphorylation in α1-null mesangial cells. Thus, our study demonstrates that integrin α1β1-EGFR cross talk is a key step in negatively regulating Rac1 activation, ROS production, and excessive collagen synthesis, which is a hallmark of diseases characterized by irreversible fibrosis.
Under a magnifying glass: On the use of experiments in strategy research

The rate at which experimental studies are published in the field of strategy has steadily increased over the past few years. Still, experimental papers account for only a small fraction of strategy papers. This may not come as a surprise given the skepticism surrounding the experimental method, which is often seen as uninterested in establishing external validity, and too “micro” for a field in which the level of analysis is primarily organizational and inter-organizational. Is this skepticism founded? To what extent can experiments be a useful tool for strategy research? To answer this question, we start by examining experimental strategy papers published between 1980 and 2016. Results from the analysis alleviate doubts about the suitability of experimental methods for the study of questions of strategic interest to firms. We next discuss the main advantages associated with the use of experiments and why they make strategy an exciting field in which to be an experimentalist today.

DNA sequence analysis of the photosynthesis region of Rhodobacter sphaeroides 2.4.1T

This paper describes the DNA sequence of the photosynthesis region of Rhodobacter sphaeroides 2.4. 1T. The photosynthesis gene cluster is located within a ~73 kb AseI genomic DNA fragment containing the puf, puhA, cycA and puc operons. A total of 65 open reading frames (ORFs) have been identified, of which 61 showed significant similarity to genes/proteins of other organisms while only four did not reveal any significant sequence similarity to any gene/protein sequences in the database. The data were compared with the corresponding genes/ORFs from a different strain of R.sphaeroides and Rhodobacter capsulatus, a close relative of R.sphaeroides. A detailed analysis of the gene organization in the photosynthesis region revealed a similar gene order in both species with some notable differences located to the pucBAC=cycA region. In addition, photosynthesis gene regulatory protein (PpsR, FNR, IHF) binding motifs in upstream sequences of a number of photosynthesis genes have been identified and shown to differ between these two species. The difference in gene organization relative to pucBAC and cycA suggests that this region originated independently of the photosynthesis gene cluster of R.sphaeroides.
Determining the Viability of the Kinect as a Research Tool

This project investigated the viability of using the Microsoft Kinect in order to obtain reliable Red-Green-Blue-Depth (RGBD) information. This explored the usability of the Kinect in a variety of environments as well as its ability to detect different classes of materials and objects. This was facilitated through the implementation of Random Sample and Consensus (RANSAC) based algorithms and highly parallelized workflows in order to provide time sensitive results. We found that the Kinect provides detailed and reliable information in a time sensitive manner. Furthermore, the project results recommend usability and operational parameters for the use of the Kinect as a scientific research tool. Determining the Viability of the Kinect as a Research Tool 7
SOLID WASTES LANDFILL MONITORING BY MEANS OF DIFFERENTIAL HIGH-RESOLUTION INFRARED THERMOGRAPHY

Differential thermal imaging has been proposed to characterize the ground temperature distribution of two solid wastes landfills. The differential approach permitted to detect regions with thermal abnormalities potentially associated with either biogas leakage and migration or improper landfill settlement and management. Methods, results, limits, and potentialities of the proposed approach are discussed.
Anti-Takeover Provisions in Corporate Spin-Offs

We analyze the relation between antitakeover provisions (ATPs) and the performance of spin-off firms. We find that firms protected by more ATPs before spin-offs have higher abnormal announcement returns and greater improvements in post-spin-off operating performance than firms with fewer ATPs. Further, firms that reduce the number of ATPs after spin-offs have greater improvements in operating performance than firms that do not reduce the number of ATPs. Finally, CEOs of pre-spin-off firms tend to retain more ATPs in parent firms and assign fewer ATPs to the spun-off units if they remain as the CEOs of the parents but not the spun-off units. Overall, our results indicate a positive relation between ATPs and the value gains to spin-offs.
PENGARUH ROM (Range of Motion) TERHADAP KEKUATAN OTOT EKSTREMITAS PADA PASIEN STROKE NON HEMORAGIC

Stroke is one of the serious health problems in modern life today. The prevalence of stroke increases with age. The World Health Organization (WHO) stipulates that stroke is a clinical syndrome with symptoms of global brain dysfunction that can cause death or abnormalities to persist for more than 24 hours, without other causes except vascular disorders which can cause a person's reduced mobility due to muscle strength downhill. This study aims to determine the effect of ROM (range of motion) on limb muscle strength in non-Hemaoragic stroke patients at H. Adam Malik General Hospital, Medan. Quasi-experimental research design with a sample of 90 people. Univariate and bivariate data analysis using the Wilcoxon test. The significance of hand muscle strength before and after administration of ROM is 0,000. This means that there are differences in hand muscle strength before and after administration of ROM. The significance of leg muscle strength before and after administration of ROM is 0,000. This means that there are differences in leg muscle strength before and after administration of ROM. This proves that ROM influences the strength of the respondent's hand and leg muscles. Hospitals should set standard operating procedures for special handling of ROM so that the results obtained can be maximal and uniform for all muscle strength problemsKeywords: ROM, limb muscle strength, hands, feet
Genetic variability of mulberry (Morus spp.) germplasm against powdery mildew (Phyllactinia corylea) and identification of high resistance genotypes

The disease response and magnitude of genetic variability of 85 mulberry genotypes of different agroclimatic origin was studied against powdery mildew caused by Phyllactinia corylea. It was observed that there was a wide variation of disease severity among the test genotypes. Australian and France originating genotypes were found to be highly resistant to mildew followed by of Thai and Italian origin. Genotype wise, the lowest mildew disease severity was recorded in Thailand [lobed]) followed by M. malticaulis, M. australis and Italian. Genetic analysis of disease severity revealed that the estimate of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were high and that PCV was greater than GCV. High estimate of heritability coupled with high genetic advance showed that the mildew disease resistant trait is governed by an additive gene action. Hence the highly resistant mulberry genotypes identified may be exploited through hybridisation followed by selection under epiphytotic conditions for the improvement of disease resistant traits in mulberry.
Cytotoxic and Apoptotic Activity of Majoranolide from Mezilaurus crassiramea on HL-60 Leukemia Cells

Majoranolide, a butanolide isolated from the nonpolar fraction of an ethanol extract of Mezilaurus crassiramea (Lauraceae) fruits, is being reported for the first time in this genus and the third time in plants. Structurally identified from 1D and 2D NMR and HRESIMS data, majoranolide proved cytotoxic against cancer cells—MCF-7 and MDA-MB-231 (breast), HT-29 (colon), PC-3 (prostate), 786-0 (renal), and HL-60 (leukemia)—inhibiting growth in HL-60 cells (GI50 = 0.21 μM) and exhibiting higher selectivity for this line than for nonneoplastic NIH/3T3 murine fibroblasts. Effects on the cell cycle, caspase-3 activation, and plasma membrane integrity were evaluated by flow cytometry. Expression of genes related to apoptotic pathways (BAX, BCL2, BIRC5, and CASP8) was investigated using RT-qPCR. At 50 μM, majoranolide induced cell cycle arrest at G1 in 24 h increased the sub-G1 population in 48 h and increased caspase-3 activation in a time-dependent manner. The compound upregulated BAX and CASP8 transcription (proapoptotic genes) and downregulated BIRC5 (antiapoptotic). Loss of plasma membrane integrity in 30% of cells occurred at 48 h, but not at 24 h, characterizing gradual, programmed death. The results suggest that majoranolide cytotoxicity involves apoptosis induction in HL-60 cells, although other mechanisms may contribute to this cell death.
Homoeology between Agropyron elongatum chromosomes and Triticum aestivum chromosomes.

Genetic compensation of Agropyron chromosomes for wheat chromosomes in the male gametophyte and compensation of Agropyron chromosomes for wheat chromosomes in disomic substitutions were used to investigate relationships between the chromosomes of Agropyron elongatum (Host.) P.B. (2n = 2x = 14) and Triticum aestivum L. emend. Thell. (2n = 6x = 42). Gametophytic compensation indicated that A. elongatum chromosomes I, II, III, IV, and VII were related to wheat chromosomes of homoeologous groups 1, 7, 4, 3, and 6, respectively, and were designated 1E, 7E, 4E, 3E, and 6E. Chromosomes V and VI appeared to be related to homoeologous group 2. Other analyses showed that chromosomes V and VI originated from arm exchanges between chromosome 2E and other Agropyron chromosomes. An unaltered disome of Agropyron chromosome 2E was added to the wheat chromosome complement. In the disomic substitutions Agropyron chromosomes 1E, 6E, and 7E compensated for all three wheat homoeologues of the respective homoeologous groups. C.
