Illusory Conjunctions: Does Inattention Really Matter?

Abstract Treisman and Schmidt (1982) found that under conditions of load, there were more conjunction errors, namely errors resulting from erroneously conjoining features from different stimuli, than feature errors, namely errors resulting from the false perception of a feature that was not presented at all. That did not occur when attention was not loaded. That interaction was argued to support feature integration theory. The attention manipulation in that study was, however, confounded with spatial uncertainty, exposure duration, and report immediacy. The present study was meant mainly to remove those confoundings. Subjects had to search for a probe in an array of three stimuli. In addition, they either had or did not have to match two outflanking digits. Exposure duration, probe type, stimulus-probe delay, and stimulus-digit delay were manipulated. Response order in the dual-task condition, and presence of digits in the single-task one were varied between subjects. Conjunction errors were found to be more frequent than feature errors, but that obtained in both attention conditions alike. That is shown to be a straightforward corrolary of the nature of these types of error that does not have implications about feature integration or perception of feature origin. Other results suggested that performance was affected by post-perceptual factors more than by perceptual ones, which casts further doubts on accounts that resort to feature integration theory.
Positive Effect of Transplantation of hNT Neurons (NTera 2/D1 Cell-Line) in a Model of Familial Amyotrophic Lateral Sclerosis

Transplantation of hNT Neurons derived from the human teratocarcinoma cell-line (NTera2/D1) has been shown to ameliorate motor dysfunction in a number of injury or disease models in which the deficits are fairly localized. However, these cells have not been used before in a model with more extensive neurodegeneration. The aim of this study is to determine the effects of hNT Neuron transplants on motor neuron function in a mouse model of familial amyotrophic lateral sclerosis (FALS) in which there is a substitution of Alanine for Glycine at position 93 of the human SOD1 gene (G93A). Amyotrophic lateral sclerosis is a fatal degenerative motor neuron disease affecting the spinal cord, brainstem, and cortex. This disease clinically manifests as progressive muscular weakness and atrophy, leading to paralysis and death within 3-5 years of diagnosis. The FALS represents 10-13% of all cases. A range of behavioral tests was used to examine spontaneous locomotor activity, coordination, and muscle strength of mice. Long-term (10-11 weeks) transplantation of hNT Neurons into the L(4)-L(5) segments of the ventral horn spinal cord of FALS(G93A) mice at 7 weeks of age (before onset of overt behavioral symptoms of disease) delayed the onset of motor dysfunction for at least 3 weeks. The average lifespan of the transplanted mice was 128 days compared to 106 days for media-injected group. The last mouse in the hNT Neuron transplanted group was euthanized at 135 days of age when it display partial paralysis of the hindlimbs. Immunohistochemical analysis of the implanted spinal cords demonstrated the survival of grafted hNT Neurons and showed many healthy-appearing motor neurons near the implant site. These results suggest that hNT Neuron transplantation may be a promising therapeutic strategy for ALS.
Multi-agent based particle filter for moving object tracking

When tracking the moving targets in video image sequences with the existing particle filter, usually the tracking performance is not satisfactory due to the particle degradation and particle diversity loss. In this paper, we propose a novel particle filtering algorithm. In the algorithm, the multi-agent co-evolutionary mechanism is introduced into the particle re-sampling process and make the particle become an agent having ability of local perception, competitive selection and self-learning by the redefinition of particle agent and its local living environment. The re-sampling process is accomplished by the co-evolutionary behaviors among particles such as competition, crossover, mutation and self-learning, etc. It can not only ensure the particle validity but also increase the particle diversity. Experimental results show that the proposed algorithm can achieve better performance when tracking objects in complex video scenes.
Anesthetic Control of 40-Hz Brain Activity and Implicit Memory

Abstract There is evidence from neuropsychological and psychophysical measurements that conscious sensory information is processed in discrete time segments. The segmentation process may be described as neuronal activity at a frequency of 40 Hz. Stimulus-induced neuronal activities of this frequency are found in the middle latency range of the auditory evoked potential (MLAEP). First, we have studied the effects of different general anesthetics on MLAEP and auditory evoked 40-Hz activity. Second, we investigated MLAEP and explicit and implicit memory for information presented during cardiac anesthesia. In the awake patients peak latencies of the MLAEP were in the normal range. An auditory evoked 40-Hz activity was present 20–100 ms poststimulus. Under nonspecific anesthetics MLAEP and the 40-Hz activity were suppressed, and under receptor-specific agents MLAEP and the 40-Hz activity were partly preserved. None of the cardiac patients had conscious explicit recall of the intraoperative events, whereas some patients showed unconscious implicit memory for an intraoperative tape message. The implicit memory could be related to midlatency auditory evoked potentials. No implicit memory was detectable when MLAEP and the primary cortical processing of the auditory stimuli and 40-Hz activity were blocked. Implicit memory could be detected in more than 50% of the cases when MLAEP, a 30-Hz activity, and the primary cortical stimulus processing were preserved. In conclusion, our observations support the view that a high frequency oscillatory mechanisms, recorded as a grouped neuronal activity in the MLAEP, may be part of a basic neuronal program for conscious sensory information processing.

Storage coding for wear leveling in flash memories

NAND flash memories are currently the most widely used flash memories. In a NAND flash memory, although a cell block consists of many pages, to rewrite one page, the whole block needs to be erased and reprogrammed. Block erasures determine the longevity and efficiency of flash memories. So when data is frequently reorganized, which can be characterized as a data movement process, how to minimize block erasures becomes an important challenge. In this paper, we show that coding can significantly reduce block erasures for data movement, and present several optimal or nearly optimal algorithms. While the sorting-based non-coding schemes require O(n log n) erasures to move data among n blocks, coding-based schemes use only O(n) erasures and also optimize the utilization of storage space.

Three New Polyacetylene Glycosides from the Roots of Heracleum dissectum and Their Triglyceride Accumulating Activities in 3T3‐L1 Cells

Continually phytochemical study of the roots of Heracleum dissectum had led to the isolation of three previously undescribed polyacetylene glycosides (1–3), together with seven known compounds, including one polyacetylene (8) and six coumarins (4–7 and 9–10) using diverse chromatographic methods. The structures of these three new compounds were characterized and identified as deca‐4,6‐diyn‐1‐yl β‐d‐glucopyranosyl‐(1→6)‐β‐d‐glucopyranosyl‐(1→2)‐β‐d‐glucopyranoside (1), (8Z)‐dec‐8‐ene‐4,6‐diyn‐1‐yl β‐d‐glucopyranosyl‐(1→6)‐β‐d‐glucopyranosyl‐(1→2)‐β‐d‐glucopyranoside (2), and (8E)‐dec‐8‐ene‐4,6‐diyn‐1‐yl β‐d‐glucopyranosyl‐(1→6)‐β‐d‐glucopyranosyl‐(1→2)‐β‐d‐glucopyranoside (3) based on their physicochemical properties and extensive analyses of various spectroscopic data. Their triglycerides accumulating activities were assayed and the results showed that the three new polyacetylene glycosides (1–3) exhibited triglyceride accumulating activities in 3T3‐L1 adipocytes.
Modelo Multicamadas para Detecção de Ataques ROP

This paper presents a multi-layer protection system to guard programs again Return-Oriented Programming (ROP) attacks. Upper layers have low computational cost; thus, they do not compromise the runtime of legitimate program executions. Lower layers provide very strong enforcement guarantees; thus, they are difficult to circumvent. Our multilayer system combines several techniques already described in the literature; however, to be practical, we had to augment them with an extra verification, which consists in checking if the target address of call instructions lays in an executable program segment. We demonstrate the effectiveness of our multilayer protection in internet banking applications taken from two among the main Brazilian banks: Banco do Brasil and Bradesco. Our experiments on these two systems and on several well-known benchmarks indicate that we can protect programs with almost no overhead in practice. Resumo. Esse artigo apresenta um sistema de proteção multicamadas para defesa de programas contra ataques de Return-Oriented Programming (ROP). Camadas superiores têm custo computacional baixo; assim, elas não comprometem o tempo de execução de programas que não estão sob ataque. Camadas inferiores proveem garantias muito fortes; assim, elas são difı́ceis de contornar. Nosso sistema multicamadas combina várias técnicas já descritas na literatura; entretanto, para serem práticas, nós tivemos que estendê-las com uma verificação extra, que consiste em checar se o endereço alvo de uma instrução de chamada de função (call) está em um segmento executável da memória. Nós demonstramos a eficiência da nossa proteção multicamadas em aplicações bancárias de dois dos principais bancos brasileiros: Banco do Brasil e Bradesco. Nossos experimentos nesses dois sistemas e em vários benchmarks populares indicam que podemos proteger programas em tempo de execução com custo quase nulo na prática.
Generar Conocimiento con las TIC en la Escuela: Una Propuesta para la Elaboración de Materiales Educativos desde la Cultura Libre .

Resumen: Los docentes de educación básica y media tienen importantes retos que afrontar para responder a los requerimientos del nuevo siglo. Aunque en ellos no recae toda la responsabilidad de transformar los paradigmas educativos, es importante aprovechar los espacios de cualificación generados por diferentes programas de dotación de TIC en las escuelas en América Latina para involucrarlos. Un aspecto es trascender el uso instrumental de estas tecnologías, asumiendo la creación de Materiales Educativos Computarizados (MEC) desde las Pedagogías Críticas y la Cultura Libre, ya que esto permite que docentes y estudiantes se asuman como constructores de conocimiento y de saber desde la escuela y en relación con el contexto cercano, pero con rigurosidad. Este escrito plantea la evolución que ha tenido un referente metodológico para la creación de MEC desde esta perspectiva, los escenarios en los que se ha venido utilizando, y ejemplos de lo que han logrado algunos docentes, principalmente de escuelas rurales, en el suroccidente colombiano.
Elucidating the mechanism of step emulsification

Three-dimensional, time-dependent direct simulations of step emulsification micro-devices highlight two essential mechanisms for droplet formation: first, the onset of an adverse pressure gradient driving a back-flow of the continuous phase from the external reservoir to the micro-channel. Second, the striction of the flowing jet which leads to its subsequent rupture. It is also shown that such a rupture is delayed and eventually suppressed by increasing the flow speed of the dispersed phase within the channel, due to the stabilising effect of dynamic pressure. This suggests a new criterion for dripping-jetting transition, based on local values of the Capillary and Weber numbers.
Gold nanosprings formed by rolled-up technique

Three-dimensional helical nanostructures have attracted a great deal of attention by the virtue of anomalous properties in mechanics, electricity, electromagnetism and optics due to their intriguing shapes. This paper mainly introduces the fabrication of novel gold nanosprings by using the rolled-up technique and studies their mechanical and piezoresistive properties. Cutting across 80 nm thick gold film deposited on silicon substrate with defective nanofiber probes, we fabricate nanosprings with variable size. Maximum elastic elongation and electromechanical resonance of one gold nanospring are measured. Furthermore, we survey its piezoresistive property. It can be inferred that low stiffness, large displacement and strong piezoresistive effect of gold nanospring make it an excellent candidate for potential application as micro electro-mechanical sensor.
Measurement of inclusive jet production and nuclear modifications in pPb collisions at √SNN = 5.02 TeV

Inclusive jet production in pPb collisions at a nucleon–nucleon (NN) center-of-mass energy of √ sNN = 5.02 TeV is studied with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 30.1 nb−1 is analyzed. The jet transverse momentum spectra are studied in seven pseudorapidity intervals covering the range −2.0 < ηCM < 1.5 in the NN center-of-mass frame. The jet production yields at forward and backward pseudorapidity are compared and no significant asymmetry about ηCM = 0 is observed in the measured kinematic range. The measurements in the pPb system are compared to reference jet spectra obtained by extrapolation from previous measurements in pp collisions at √ s = 7 TeV. In all pseudorapidity ranges, nuclear modifications in inclusive jet production are found to be small, as predicted by next-to-leading order perturbative QCD calculations that incorporate nuclear effects in the parton distribution functions.
Expression of TGFβ2 but Not TGFβ1 Correlates with the Deposition of Scar Tissue in the Lesioned Spinal Cord

Abstract Transforming growth factor-βs (TGFβs) are implicated in fibrotic pathologies. TGFβ1 and -β2 expression is increased around the glial/fibrotic scar in the injured brain. Moreover, local injection of TGFβ antagonists into cerebral wounds reduces glial scarring. Here, we monitored expression of TGFβ1 and -β2 mRNA and protein in the spinal cord after transection of the dorsal funiculi. Levels of TGFβ1 mRNA were most elevated over the acute inflammatory phase, while TGFβ2 mRNA levels were raised locally about the wound, particularly in astrocytes and neovascular endothelial cells, over the subacute period of scarring. TGFβ protein production also increased after injury. Both TGFβ1 and TGFβ2 were found in hematogenous inflammatory cells, while TGFβ1 was also neuron-associated, and high levels of TGFβ2 were localized to multiple cell types in the wound, including reactive astrocytes, during the period of glial/collagen scar formation. The cellular localization and temporal pattern of expression of TGFβ after spinal cord injury suggest that TGFβ1 modulates the inflammatory and neuronal responses, while TGFβ2 regulates glial/collagen scarring.
STUDENTS? UNDERSTANDING OF SALT DISSOLUTION: VISUALIZING ANIMATION IN THE CHEMISTRY CLASSROOM

STUDENTS’ UNDERSTANDING OF SALT DISSOLUTION: VISUALIZING ANIMATION IN THE CHEMISTRY CLASSROOM. by Ummuhan Malkoc, PhD. , 2017 College of Education Texas Christian University Dissertation Advisor: Dr. Molly Weinburgh, Professor and William L. & Betty F. Adams Chair of Education The present study explored the effect of animation implementation in learning a chemistry topic. 135 high school students taking chemistry class were selected for this study (quasi-experimental groups = 67 and control groups = 68). Independent samples t-tests were run to compare animation and control groups between and within the schools. The over-arching finding of this research indicated that when science teachers used animations while teaching salt dissolution phenomena, students will benefit the application of animations. In addition, the findings informed the TPACK framework on the idea that visual tools are important in students’ understanding of salt dissolution concepts.
Knowledge Based Community Sharing System

:- Today the majority of the instructive foundations in India is understaffed and does not have an essential connection with industry. It now exists such that Industries are currently not some portion of the training framework. Giving a domain to understudies/workforce/analyst/industry specialists will drive us to make up an online learning place for training and research. The essential thought of KBCSS is to give a domain to the understudies and workforce of a college to upgrade their specialized aptitudes and to impart their insight to their kindred understudies or personnel/scientists/mechanical specialists. It likewise intends to give a stage to shared collaboration between various types of clients, learning by mining (i.e., past exchanges are a source which is considered). We firmly need to supplant the current e-learning frameworks of numerous colleges and schools which are unidirectional i.e., from personnel to understudies to a bidirectional way i.e., likewise from understudy to workforce.
Czy ciemna triada cech osobowości przewiduje zachowania związane z sekstingiem? Badania empiryczne w grupie młodych Polaków

Seksting jest formą wymiany prowokatywnych i seksualnie sugestywnych treści (zdjec, filmow lub wiadomości) za pomocą wiadomości tekstowych lub internetu. Badania wskazują na to, ze seksting jest zachowaniem ryzykownym, czesto związanym z przymusem, ktore moze miec związek ze zdrowiem psychicznym. Celem badania bylo sprawdzenie, czy cechy osobowości, takie jak psychopatia, makiawelizm i narcyzm (tzw. ciemna triada), przewidują zachowania związane z sekstingiem. Przebadano grupe 314 mlodych Polakow w wieku 16–19 lat. Uzyskane wyniki wskazują, ze mlodzi Polacy angazują sie w zachowania związane z sekstingiem, a czestotliwośc takich zachowan jest związana z osobowością i plcią osoby badanej. Osoby, ktore wysylaly wiecej sekstingu, charakteryzowaly sie wyzszym poziomem makiawelizmu i nizszym poziomem psychopatii. Co do otrzymywania prowokatywnych i seksualnie sugestywnych treści, to osoby o wyzszym poziomie makiawelizmu otrzymywaly ich wiecej. Niniejsze badania wskazują na związek osobowości z wysylaniem i otrzymywaniem seksualnie sugestywnych i prowokatywnych treści.
