Crowd-Sourced Speech Corpora for Javanese, Sundanese, Sinhala, Nepali, and Bangladeshi Bengali

We present speech corpora for Javanese, Sundanese, Sinhala, Nepali, and Bangladeshi Bengali. Each corpus consists of an average of approximately 200k recorded utterances that were provided by native-speaker volunteers in the respective region. Recordings were made using portable consumer electronics in reasonably quiet environments. For each recorded utterance the textual prompt and an anonymized hexadecimal identiﬁer of the speaker are available. Biographical information of the speakers is unavailable. In particular, the speakers come from an unspeci-ﬁed mix of genders. The recordings are suitable for research on acoustic modeling for speech recognition, for example. To validate the integrity of the corpora and their suitability for speech recognition research, we provide simple recipes that illustrate how they can be used with the open-source Kaldi speech recognition toolkit. The corpora are being made available under a Creative Commons license in the hope that they will stimulate further research on these languages.
Title Improved Sensing Characteristics of a Novel Pt / HfTiO 2 / SiCSchottky-Diode Hydrogen Sensor

A novel metal–insulator–silicon carbide Schottkydiode hydrogen sensor with HfTiO2 gate insulator annealed in three different gases (N2, O2, or NO) is fabricated. Measurements are carried out at various hydrogen concentrations at high temperature using a computer-controlled measurement system. The hydrogen-sensing characteristics of the devices are studied with the help of ellipsometry, transmission electron microscopy, scanning electron microscope, energy-dispersive spectroscopy, and atomic force microscopy. Experimental results show that these sensors have high sensor output and can give significant response even at low hydrogen concentration. This work also finds that the NO-annealed sensor has the highest sensor output. When 800-ppm H2 in N2 gas is introduced, the NO-annealed sensor exhibits a high sensor output of 782% at 450 ◦C, which is about three and six times higher than those of the O2and N2-annealed sensors, respectively. As compared to another sensor with HfO2 gate insulator annealed in NO, the proposed NO-annealed sensor shows higher sensor output, which should be mainly attributed to the larger barrier height at the metal–insulator interface. The excellent hydrogen-sensing characteristics of this novel sensor make it very suitable for detecting hydrogen leakage, particularly in high-temperature environments.
Linking Band-Limited Cortical Activity to fMRI and Behavior

limited electrophysiological mass activity to behavior on the one hand, and to the BOLD fMRI signal on the other. Electrophysiological mass activity generally re! ects several different components of neuronal activity, which are generated by distinct neural mechanisms and expressed in different frequency ranges. The relative strengths of these components thus determine a so-called speci"c spectral "ngerprint of a perceptual or cognitive process. A striking discrepancy between the spectral "ngerprint of stimulus-driven responses in sensory cortices and the "ngerprints of intrinsic processes (such as top-down attention or switches between perceptual states) within the same cortical areas is highlighted. It is proposed that this dissociation re! ects recurrent interactions between distant cortical areas and/or neuromodulation of cortical activity patterns by ascending systems, which are both thought to play an important role in such processes.
Biological Control of Grapevine Crown Gall Caused by Allorhizobiumvitis using Bacterial Antagonists

The potential use of bacterial antagonists isolated from different area in Morocco for the biological control of grapevine crown gall caused by Allorhizobiumvitis was investigated. In vitro analyzing the activity of 90 bacterial isolates towards Allorhizobiumvitis strain S4 resulted in a selection of 26 biocontrol agents. The isolated were tested for their ability in vitro to inhibit the growth of the pathogen. Among these isolates 12 antagonists are efficient. Molecular identification of selected isolates, using rDNA 16S sequencing, show that the antagonists belong to different genera as Bacillus spp. , Pantoea sp. , Rahnella sp. , Acinetobacter spp. and Enterobacter sp. Four antagonists were tested for their antagonistic effect in planta; they exhibited considerable inhibitory activity to reduce the incidence of galls in tomato and squash fruits. Rahnellaaquatilis and Pantoeaagglomerrans reduced the incidence of crown gall up to 100% both in tomato and squash fruits. Bacillus subtilis reduced the incidence of gall development to 75% in squash fruits and 60% in tomato. Whereas, Acinetobacter calcoaceticus reduced incidence of gall formation to 65% in squash fruits and 47% in tomato. Consequently, the treatment with bacterial antagonists may be used as an effectiveness alternative to control crown gall disease.
Distribution of two pine processionary moth species in Turkey evidences a contact zone

The pine processionary moths Thaumetopoea pityocampa and T. Wilkinsoni are among the most important Mediterranean pine defoliators. Although recent studies suggest that the two species may coexist in Turkey, the relevant literature lacks precise information on the occurrence and exact distribution of the two species in this country. In particular, whether the two sister taxa form a contact zone is still unknown. In this study, we aimed to reveal the limits of the ranges of the two species in Turkey by using nuclear (ITS-1, photolyase) and mitochondrial markers (COI). Multilocus molecular characterization of the two species showed for the first time that the two species co-occur in some of the sampling sites. In addition, we determined clear signatures of mitochondrial introgression between the two species, and therefore the existence of a possible hybrid zone within Turkey. These results bring up interesting questions relating to the evolution of the identified hybrid zone.
NEAR-MISS DETERMINATION THROUGH USE OF A SCALE OF DANGER

NEAR-MISS TRAFFIC EVENTS HAVE BEEN CONSIDERED BUT NOT ADOPTED AS A TRAFFIC SAFETY TOOL BECAUSE OF THE HIGH DEGREE OF SUBJECTIVITY INVOLED WITH THEIR IDENTIFICATION. A SCALE OF DANGER MAY BE APPLIED TO A TRAFFIC EVENT TO FACILITATE OBJECTIVE MEASUREMENT AND SUBSEQUENT DETECTION OF NEAR-MISS SITUATIONS. THE UNIT PROPOSED HERE FOR THIS DANGER SCALE IS THE TIME MEASURED UNTIL COLLISION BETWEEN TWO VEHICLES INVOLVED IN THE UNSAFE EVENT. THIS MEASURE, COMPUTED FROM FILMS TAKEN WITH THE TRAFFIC SENSING AND SURVEILLANCE SYSTEM OF THE FEDERAL HIGHWAY ADMINISTRATION AT AN URBAN INTERSECTION, IS AN ADEQUATE UNIT TO RATE THE DANGER OF ALMOST ANY TRAFFIC EVENT. IT MAY BE USED TO STANDARDIZE HUMAN OBSERVER JUDGEMENT OF DANGEROUS MANEUVERS AND, THEREFORE, MAKE NEAR-MISS MONITORING A VIABLE ALTERNATIVE TO TRAFFIC SAFETY DETERMINATION. /AUTHOR/
Decolourization and Biological Treatment of Pulp and Paper Mill Effluent by Lignin-Degrading Fungus Aspergillus flavus Strain F10

A potential lignin-degrading fungal strain, identified as Aspergillus flavus strain F10 have been studied for the treatment of pulp and paper mill effluent. The results of this study revealed that A. flavus effectively reduced the colour and lignin content (in the term of total phenolic content). It reduces colourity up to 31–51 % and lignin content 39–61%in ten days of incubation when used as a free form, while in immobilized condition it reduces more colourity and lignin content within 6 day of treatment. A significant reduction in color and lignin content by this fungus strain was observed after four days of incubation, indicating that fungus subsequently utilized chromophoric compounds thereby reducing lignin content and color. The toxicity of paper and pulp effluent was measured in the term of phytotoxicity. A high germination index of treated samples indicate that the treatment have reduced pollution load in effluent to low levels which are not toxic to plants.
An Architecture for a Widely Distributed Storage and Communication Infrastructure

With the advancement of technology, richer computation devices are making their way into everyday life. However, such smarter devices merely act as a source and sink of information; the storage of information is highly centralized in data-centers in today’s world. Even though such data-centers allow for amortization of cost per bit of information, the density and distribution of such data-centers is not necessarily representative of human population density. This disparity of where the information is produced and consumed vs where it is stored only slightly affects the applications of today, but it will be the limiting factor for applications of tomorrow. The computation resources at the edge are more powerful than ever, and present an opportunity to address this disparity. We envision that a seamless combination of these edge-resources with the data-center resources is the way forward. However, the resulting issues of trust and data-security are not easy to solve. Toward this vision of a federated infrastructure composed of resources at the edge as well as those in data-centers, we describe the architecture and design of a widely distributed system for data storage and communication that attempts to alleviate some of these data security challenges; we call this system the Global Data Plane (GDP). The core idea of GDP is a secure single-writer append-only log, which provides a layer of uniformity on top of a heterogeneous infrastructure. This secure single-writer log is a unified storage and communication primitive that represents a refactoring of interfaces. Such a refactoring enables cleaner application design that allows for better security analysis of information flows. Not only cleaner design, GDP also enables locality of access for performance and data privacy—an ever growing concern in the information age. Note that Global Data Plane is an ongoing project and is evolving continuously. This document is an adaptation of a doctoral thesis proposal and merely documents the ideas at a certain point in time. For more current information, please see the project web-page at https://gdp.cs. berkeley.edu. Since the time of this writing, we have changed the name of ‘secure single-writer append-only log’ to DataCapsule in the GDP. We believe that this change of terminology better reflects the desired properties and avoids the confusion with a simple log file.
Delay-Tolerant Bulk Information Transfers on the Web

Many rising scientific and industrial applications require transferring multiple terabytes of knowledge on a commonplace. Examples include pushing scientific information from particle accelerators colliders to laboratories round the world, synchronizing datacenters across continents, and replicating collections of high-definition videos from events going down at totally different timezones. Akey property of all higher than applications is their ability to tolerate delivery delays ranging from many hours to many days. Such delay-tolerant bulk (DTB) information square measure presently being serviceable largely by the communication system victimization arduous drives and DVDs, or by pricy dedicated networks. In this paper, we tend to propose sending such information through commercial ISPs by taking advantage of already-paid-for off-season bandwidth ensuing from diurnal traffic patterns and grade pricing. we tend to show that between sender–receiver pairs with tiny time-zone distinction, straightforward supply programming policies square measure able to take advantage of most of the present off-season capability. When the time-zone distinction will increase, taking advantage of the complete capability requires playing store-and-forward through intermediate storagenodes. We gift an in-depth analysis of the two options supported traffic information from 200+ links of an outsized transit provider with points of presence (PoPs) at 3 continents. Our results indicate that there exists Brobdingnagian potential for playing multiterabyte transfers on a common place at very little or no further price.
Optimal speed of detection in generalized Wiener disorder problems

We de0ne a general Wiener disorder problem in which a sudden change in a time pro0le of unknown size has to be detected in white noise of small intensity. Since both the time of the change and its size are unknown, this problem is considerably harder than standard Wiener disorder problems where the size of the change is assumed to be known a priori. We formulate the problem within the Bayesian framework of nonlinear 0ltering theory, and use Strassen’s functional law of the iterated logarithm to bound stochastic measures which arise in the nonlinear 0ltering equations. This leads to explicit expressions for the detection delay in the optimal statistics for small noise intensities, and we indicate how these can be used to analyse the detection delays of recursive suboptimal detection algorithms for this problem.
The Impact of Automated Code Quality Feedback in Programming Education

While some university-level programming courses focus on software quality, often in introductory courses code quality is little touched upon due to time constraints. Students usually get feedback on code quality after the grading of their assignment, feedback that cannot be used on that same assignment. Our aim is to improve students’ skills for code quality during the evolution of a students’ programming assignment, while keeping the overhead low for teaching sta↵ as well as for students. Better Code Hub is a service that checks code quality according to ten guidelines. We employ Better Code Hub as a formative assessment and feedback tool enabling students to monitor their progress on code quality. Our findings indicate that there is an improvement in the code quality of the students’ assignments over the period the tool is used. Our experiments show that students benefited the most from feedback on unit length, unit complexity, and code duplication. Copyright c by the paper’s authors.

Chapter 6 Making New Strategic Moves Possible: How Executive Management Enacts Strategizing Routines to Strengthen Entrepreneurial Agility

In this chapter, the authors describe and explain how executive management enacts strategizing routines to strengthen their entrepreneurial agility, as a precondition to make new strategic moves possible. The authors contribute to the routine dynamics research program, by showing how the dynamics of routines, in a strategy context, shape strategic outcomes: the authors describe four strategizing routines – distancing, evaluating, experimenting, and re-assembling – as a particular promising focus for routine and strategy research. The authors discuss executive management’s enactment of such routines as part of their strategy work. The authors show how routine enactment makes entrepreneurial agility and new strategic moves possible. By exploring the dynamics of strategizing routines and their impact on strategic outcomes, the authors at the same time benefit from and contribute to the strategy-as-practice research program. Empirically, the authors study how the executive management of Hoechst AG successfully made unthinkable new strategic moves possible, discussable, and realizable in the context of the corporation’s strategic transformation between 1994 and 1996.
A uniform-sensitivity omnidirectional shear-horizontal (SH) wave transducer based on a thickness poled, thickness-shear (d15) piezoelectric ring

The fundamental shear horizontal (SH0) wave in plates is of great importance in the field of nondestructive testing (NDT) and structural health monitoring (SHM) since it is the unique non-dispersive guided wave mode. For practical applications, a phased array system based on omnidirectional SH0 wave transducers is most useful as it can cover a wide range of a plate. However, so far very few omnidirectional SH wave transducers have been developed. In this work, we proposed an omnidirectional SH wave piezoelectric transducer (OSH-PT) based on a thickness poled piezoelectric ring. The ring is equally divided into twelve sectors and the electric field is circumferentially applied, resulting in a new thickness-shear (d15) mode. Finite element analysis shows that the proposed OSH-PT can excite single-mode SH0 wave and receive the SH0 wave only. Experiments were then conducted to examine the performance of the proposed OSH-PT. Results indicated that it can generate and receive single-mode SH0 wave in a wide frequency range with nearly uniform sensitivities along all directions. Considering its quite simple configuration, compact size and low cost, the proposed OSH-PT is expected to greatly promote the applications of SH waves in the field of NDT and SHM.
EFFECTS OF MISSING A PRICE PROMOTION AFTER PURCHASING ON PERCEIVED PRICE UNFAIRNESS , NEGATIVE EMOTIONS , AND BEHAVIORAL

In this study we sought to examine now consumers perceive price unfairness when they leam that they have missed a price promotiou qjter making a purchase, and explore the accompanying negative emo tions and behaviora l responses. The promotions that consumers learn they have missed could occur either before purchasing (i.e., prepurchase promotion) or after purchasing (i.e., postpurchase promotion). By conducting a 2 (attribution of responsibility: internal vs. external attribntion) x 2 (time of the missed promotio n: prepurchase vs. postpnrchase promotion) experiment with 202 part icipants, we found that greater perceived price unfairness (PPU) is generated when consumers attribute missing the promotion to the sellers ' actions. Additio nally, PPU is more likely to induce anger than disappointment and regret. The time of the missed promo tion alters the impact of PPU on regret, Lastly, consumers who experience high levels of anger and disappointment tend to complain and spread negative word of mouth while those who experience high regret tend to be inactive.
Promoting Self-Directed Revision in EFL Writing Classes.

Second language writers need to develop the ability to revise their writing independently of third party advice; thus, it is important that teachers devise methods by which to promote habits of self-directed revision. This quasi-experimental study investigates three classroom activities designed to encourage students to independently revise essays prior to receiving teacher feedback. One class of second-year Japanese university students revised the Oirst draft of an essay after completing the following activities: 1) an oral presentation of essays; 2) a grammar workshop; and 3) a 20-point checklist. A second class was designated as a control group and revised their essays with no additional input. Teacher feedback was provided on the second drafts in the same way to each group. It was found that the treatment group made almost three times as many revisions to their Oirst drafts. This group’s revisions were also more successful, with 80% having improved on the Oirst drafts, compared to 66% of those made by the control group. However, on the teacher-reviewed second drafts, the majority of revisions derived from teacher feedback; less than 15% of revisions made by both groups were self-directed.
In vitro propagation of Cleome gynandra L. through direct organogenesis

An efficient protocol was developed for in vitro regeneration of Cleome gynandra L. is a herb belonging to the family Cleomaceae. In the present study, shoot tip explants of Cleome gynandra were cultured on MS medium supplemented with different concentrations of BAP and Kin (5-25 μM/l) alone or in combination with IAA (2 – 10 μM/l ) for multiple shoot bud induction. The highest frequency (100%) of shoot bud induction and maximum number of shoot buds (26.4±0.48) was noticed on 10μM BAP with mean shoot length of 8.2 cm. The shoot proliferation was further improved by combination of BAP+IAA. The maximum number of shoots (35.8± 1.42) was developed on MS media containing 10 μM/l BAP in combination with 2 μM/l IAA. The regenerative shoot buds were transferred to half strength MS medium fortified with different concentrations of IBA and NAA (2-10μM/l) for root induction. The maximum numbers of roots (17.2±1.95) were obtained from 4μM NAA with mean root length of 3.6 cm. In vitro regenerative plantlets were successfully acclimatized in red soil, farmyard manure and sand (2:1:1). Subsequently, the plants were successfully established in the field.
Pixel Redrawn For A Robust Adversarial Defense

Recently, an adversarial example becomes a serious problem to be aware of because it can fool trained neural networks easily. To prevent the issue, many researchers have proposed several defense techniques such as adversarial training, input transformation, stochastic activation pruning, etc. In this paper, we propose a novel defense technique, Pixel Redrawn (PR) method, which redraws every pixel of training images to convert them into distorted images. The motivation for our PR method is from the observation that the adversarial attacks have redrawn some pixels of the original image with the known parameters of the trained neural network. Mimicking these attacks, our PR method redraws the image without any knowledge of the trained neural network. This method can be similar to the adversarial training method but our PR method can be used to prevent future attacks. Experimental results on several benchmark datasets indicate our PR method not only relieves the over-fitting issue when we train neural networks with a large number of epochs, but it also boosts the robustness of the neural network.
Precision interferometric measurements of refractive index of polymers in air and liquid

We have developed a procedure for precise measurement of the group refractive index for materials in air and liquid environments, using a low coherence interferometer. For example, in manufacturing of soft contact lenses, the lenses are always kept hydrated in a saline solution. Knowing accurate refractive index of the lens is important to metrology and quality control purposes. The small refractive index difference between the liquid and the lens makes such tasks especially challenging. The developed procedure allows us to obtain measurement repeatability for group refractive index less than 1 x 10-3 for materials with thicknesses on the order of 100 microns, when measured in liquid. The measurement repeatability further improves for measurements in air, or for thicker materials.
