Human Action Recognition by Learning Spatio-Temporal Features with Deep Neural Networks

Human action recognition plays a crucial role in various applications, including video surveillance, human-computer interaction, and activity analysis. This paper presents a study on human action recognition by leveraging CNN-LSTM architecture with an attention model. The proposed approach aims to capture both spatial and temporal information from videos in order to recognize human actions. We utilize the UCF-101 and UCF-50 datasets, which are widely used benchmark datasets for action recognition. The UCF-101 dataset consists of 101 action classes, while the UCF-50 dataset comprises 50 action classes, both encompassing diverse human activities. Our CNN-LSTM model integrates a CNN as the feature extractor to capture spatial information from video frames. Subsequently, the extracted features are fed into an LSTM network to capture temporal dependencies and sequence information. To enhance the discriminative power of the model, an attention model is incorporated to improve the activation patterns and highlight relevant features. Furthermore, the study provides insights into the importance of leveraging both spatial and temporal information for accurate action recognition. The findings highlight the efficacy of the CNN-LSTM architecture with an attention model in capturing meaningful patterns in video sequences and improving action recognition accuracy.

Behavioral intention & use behavior of citizens in Iligan city towards the staysafe.ph application during the covid 19 pandemic

The Covid-19 pandemic has encouraged the use of digital solutions such as contact tracing applications to manage the spread of the virus infection. The use of Staysafe.ph app in particular is central to the management of public health emergencies in the country, however, it is important to understand the needs and tolerances of different users to address factors that may hinder the adoption of such strategy. Prior research in contact-tracing apps focuses solely on measuring people’s intentions to use the app. However, the effectiveness of contact-tracing apps is dependent on a significant percentage of the population installing and using the app. Hence, to investigate the intention to use and usage behavior of citizens towards the Staysafe.ph application during the pandemic, the UTAUT model is used, expanding it with three constructs: privacy concern and self-efficacy as direct determinants for behavioral intention; and fear of Covid-19 as a moderator. A survey experiment (N = 400) in Iligan City is used, in which a web-based version of the survey questionnaire was distributed through social networks. The measurement and structure model were appraised using structural equation modelling (SEM). The result shows that effort expectancy, social influence, facilitating conditions, and self-efficacy played an important role in behavioral intention and usage of the app, except for performance expectancy and privacy concerns. Moreover, respondents showing behavioral intention to use the application are more likely to use the app. The multiple regression analysis showed that fear of Covid-19 and age as moderating factors do not have a significant impact on behavioral intention and use behavior. These findings were interpreted in the light of current conceptualizations in the area of the study and their implications for the future were pointed out.

The Chihuahua and the Space Princess writing in the margins: Antenarratives of two (older) women early career academics

AbstractIn asking “why is it so bloody hard for older women, with years of professional experience in industry and graduate degree holders, to create a career in the Academy?,” the authors co‐examine the challenges they experience in their careers and in their transition into academia. Framed within intersectionality scholarship, specifically anchor points, the authors' nonnormative positioning as older ciswomen, early career academics, who are attempting to find tenured positions, showcase their fluid living stories of sexism and ageism while trying to negotiate a career transition. Using a duoethnographic methodology, the authors share and then analyze their embodied, fragile antenarratives as they understand them at this point in time. In the process of writing differently, literally at the left and right margins of content and style, and in the analysis of these writings, they discover that they can begin to resist the gendered ageism from the margins and that they are no longer alone. They navigate a path of resistance, laboring against the norms that try to relegate two older women, early career academics' stories to silence, inviting others into their living story network.

Neck of the woods: Microbes, memory, and resistance

Horizontal Gene Transfer (HGT) is a key mechanism allowing bacteria to enact genetic changes in response to shifting environmental conditions. The swift lateral movement of genes makes possible antibiotic resistance, which is an increasing medical and ultimately cultural problem. There is evidence that HGT also takes place between species. Bacterial DNA appears in the human mitochondrial genome of acute myeloid leukemia (AML) samples. Responding to a recent diagnosis of AML, this creative piece imagines a literary form of HGT. Adjacency is intrinsic to the conceptual and formal concerns of the text. Moving back and forth between essay and poem, between the personal and the planetary, between the real and the imagined, and between the right and left margins of the page, this piece unfolds beside itself, exploring the lateral movement of memory and family history through concerns with antibiotic resistance, illness, writing, and science. While there are no embedded citations or footnotes, a glossary of terms (Appendix 1) follows the main text, and a brief bibliographic essay (Appendix 2) at the end identifies cited sources that correspond to a list of references.

Method of measuring the surface profile by means of a mechatronic profilograph provided with a parallel control of sensor drives

The article considers a method for measuring the surface profile by means of a mechatronic profilograph provided with parallel control of sensor drives along a specified trajectory. A description of the developed control system for the mechatronic profilograph with distributed control of its actuators is presented. The given design of the control system makes it possible for the operating unit (laser sensor) of the profilograph to effectively perform the programed movements. The developed software implements a set of functions necessary for parallel control of the profilograph drives, depending on the specified on-line operating modes. The program allows you to set parameters and control instructions for lower-level modules, tabulate data on the movement of the working point along the x, y axes and distances in these coordinates as well as to construct 2D and 3D graphs. The implementation of the method for measuring the surface profile was carried out using a mechatronic profiler provided with parallel control of the sensor drives when profiling along the Fermat spiral. The information and measurement system made it possible to provide information on 2 parameters: the distance between the sensor and the measured surface, as well as the angle of turning determined by the angle sensor from the zero point. A graph of the measurement of the corrugated sheet surface with a flexure in the cross section downwards in polar coordinates is obtained. The analysis of the obtained data allowed us to determine the corrugated sheet flexure which was 13.8 mm.graph, immediately following the heading. The text should be set to 1 line spacing.

Target position and avoidance margin effects on path planning in obstacle avoidance

This study examined how people choose their path to a target, and the visual information they use for path planning. Participants avoided stepping outside an avoidance margin between a stationary obstacle and the edge of a walkway as they walked to a bookcase and picked up a target from different locations on a shelf. We provided an integrated explanation for path selection by combining avoidance margin, deviation angle, and distance to the obstacle. We found that the combination of right and left avoidance margins accounted for 26%, deviation angle accounted for 39%, and distance to the obstacle accounted for 35% of the variability in decisions about the direction taken to circumvent an obstacle on the way to a target. Gaze analysis findings showed that participants directed their gaze to minimize the uncertainty involved in successful task performance and that gaze sequence changed with obstacle location. In some cases, participants chose to circumvent the obstacle on a side for which the gaze time was shorter, and the path was longer than for the opposite side. Our results of a path selection judgment test showed that the threshold for participants abandoning their preferred side for circumventing the obstacle was a target location of 15 cm to the left of the bookcase shelf center.

Research review on cutting temperature and cutting vibration of titanium alloy

The text should be set to 1 line spacing. The abstract should be centred across the page, indented 17 mm from the left and right page margins and justified. It should not normally exceed 200 words The titanium alloy called “strategic metal” is a typical refractory material that causes high temperature and vibration during cutting due to its high strength, low thermal conductivity and low elastic modulus. In the processing process, the tool wear is serious, and the accompanying cutting heat and cutting vibration are coupled to each other and change with time. Studying the temperature and vibration characteristics in the processing process is conducive to further understanding of cutting mechanism, better controlling temperature and vibration, improving cutting processing quality and reducing production cost. This paper reviews the current situation of cutting temperature and cutting vibration at home and abroad. Scholars focus on the influence of cutting factors on temperature and vibration, based on finite element simulation and mathematical modeling, and the research on temperature and vibration coupling of titanium alloy cutting should be further strengthened.

The genetic structure of Pristimantis latro (Anura: Craugastoridae) mirrors traits of their life history

One of the main hypotheses to explain the origin of Amazonian diversity is the barrier effect of the rivers known as the riverine-barrier hypothesis, which suggests that riverine barriers isolated once continuous populations leading to differentiation and speciation. In this context, we studied the genetic structure of Pristimantis latro, a newly described species that inhabits a region under marked anthropic pressure due to expansive livestock, illegal mining, and hydroelectric dam construction. The DNA was extracted from 52 P. latro individuals and then amplified via polymerase chain reaction (PCR) using the mitochondrial 16S rRNA and COI markers. To infer the time of divergence between the P. latro localities, we built a species tree and performed an analysis of molecular variance (AMOVA) to infer the genetic differentiation between and within the P. latro populations. We found that P. latro has a marked genetic structure in the populations of the right and left margins of the Xingu River and within the Tapajós-Xingu and Xingu-Tocantins interfluvial regions and that the time of divergence between the populations of the East and West banks of the Xingu River occurred approximately 380,000 years ago. This pattern of genetic structure corresponds to that reported in recent articles for the Pristimantis genus evidencing that species without tadpoles exhibit a genetic structure explained by the hypothesis of rivers as barriers.

Hyperspectral imaging for colon cancer classification in surgical specimens: towards optical biopsy during image-guided surgery.

The main curative treatment for localized colon cancer is surgical resection. However when tumor residuals are left positive margins are found during the histological examinations and additional treatment is needed to inhibit recurrence. Hyperspectral imaging (HSI) can offer non-invasive surgical guidance with the potential of optimizing the surgical effectiveness. In this paper we investigate the capability of HSI for automated colon cancer detection in six ex-vivo specimens employing a spectral-spatial patch-based classification approach. The results demonstrate the feasibility in assessing the benign and malignant boundaries of the lesion with a sensitivity of 0.88 and specificity of 0.78. The results are compared with the state-of-the-art deep learning based approaches. The method with a new hybrid CNN outperforms the state-of the-art approaches (0.74 vs. 0.82 AUC). This study paves the way for further investigation towards improving surgical outcomes with HSI.

Mind your step: learning to walk in complex environments

In everyday contexts, children must respond to both self-related constraints (their own skills and abilities) and environmental constraints (external obstacles and goals). How do young children simultaneously accommodate these to support skilled and flexible behaviour? We used walking in a complex environment as a testbed for two hypotheses. Hypothesis 1: children will accommodate the self-related constraint of high foot placement variability via dynamic scaling. Hypothesis 2: children will plan ahead, even in complex environments. In our task, 3- to 5-year-olds and adults walked over obstacle sequences of varying complexity. We measured foot placement around the first obstacle in the sequence. Hypothesis 1 was partially supported. In simple, single obstacle environments, children engaged in dynamic scaling like adults. Those with more variable foot placement left greater margins of error between the feet and the obstacle. However, in complex, multiple obstacle settings, children employed large, un-tailored margins of error. This parallels other multisensory tasks in which children do not rely on the relative variability of sensory inputs. Hypothesis 2 was supported. Like adults, children planned ahead for environmental constraints. Children adjusted foot placement around the first obstacle depending on the upcoming obstacle sequence. In doing so, they demonstrate surprisingly sophisticated planning. We, therefore, show that in the motor domain, even very young children simultaneously control both self-related and environmental constraints. This allows flexible, safe and efficient behaviour.

Two New Endozoic Ciliates, Clevelandella lynni sp. n. and Nyctotherus galerus sp. n., Isolated from the Hindgut of the Wood-feeding Cockroach Panesthia angustipennis (Illiger, 1801).

Two new ciliate species, Clevelandella lynni sp. n. and Nyctotherus galerus sp. n., were discovered in the hindgut of wood-feeding panesthiine cockroaches. Their morphology was studied using standard methods, and their phylogenetic positions within the order Clevelandellida were determined using the 18S rRNA gene sequences. Clevelandella lynni is characterized by a prominent peristomial projection, a notched left body margin, a tear-shaped to broadly ovoidal macronucleus, a karyophore attached to the right body margin, and by an adoral zone composed of on average 48 membranelles and extending about 51% of body length. The diagnostic features of N.galerus include a short posterior body projection, a spherical to broadly ellipsoidal macronucleus, a karyophore attached to the right and left body margins, refractile bodies densely packed anterior to the macronucleus, and an adoral zone composed of on average 57 membranelles and extending about 70% body length. The order Clevelandellida was consistently depicted as monophyletic in 18S rRNA gene phylogenies. Nyctotherus galerus was placed in the paraphyletic family Nyctotheridae, as sister taxon to all other Nyctotherus and Clevelandella species isolated from cockroaches. Clevelandella lynni fell in the monophyletic family Clevelandellidae, as sister taxon to C.panesthiae KC139718 but with very poor statistical support.

Detecting neotectonics in the lowlands of Amazonia through the analysis of river long profiles

There has been a considerable number of studies focusing on the analysis of river long profiles based on stream power incision models aiming to detect areas affected by neotectonics. Most of these studies have successfully uncovered active tectonics in mountainous landscapes, with some examples in areas of low reliefs around the globe. However, this kind of investigation has rarely been used in large tropical lowlands, such as the Amazonian lowlands, where the application of river long profiles is still challenging. The main aim of the present work was to test the functionality of methods based on river profiles to detect neotectonic reliefs in lowland landscapes. The Negro River basin was selected for this investigation, assuming the several indications of tectonic activity during the late Pleistocene and Holocene. We tested the normalized channel steepness index (ksn), with the identification of knickpoints and interpretation of swath profiles, computed from the 30 m digital elevation model provided by the Shuttle Radar Topography Mission. The results showed streams with profiles bounded by a set of knickpoints represented by very low ksn values in the right (average ksn = 8) and left (average ksn = 10) margins of the Negro River. These values contrast with the high range of ksn values generally found for rivers of tectonically active mountainous landscapes. Even with low values, we verified that a slight increase in ksn values was enough to detect transient rivers related with strike slip faults in Amazonia lowlands. The swath profiles also showed sectors on relief compatible with changes in the base level of the tributaries, with the record of knickpoints and an increase in ksn values. The experimental results obtained in this work motivate further quantitative investigation in Amazonian lowlands by testing geological data with new robust techniques from river profiles.

Factors Affecting Arabic Handwriting of a Sample of Adult Egyptian Twins

Introduction: Both of heredity and the environment may play a crucial role in development of a person's handwriting. This study aimed to investigate the degree of similarity in Arabic handwriting of twins and features of Arabic handwriting in relation to some environmental factors. Methods: The study included 40 pairs of adult Egyptian twins (20 identical and 20 fraternal pairs). The study investigated the effects of genetic factor as well as two environmental factors (primary language of education and drawing practice) on Arabic handwriting of the included subjects. Results: There was no significant difference between identical and fraternal twins in frequency of similar pairs in the characteristics of Arabic handwriting. Subjects whose primary language of education was Arabic language were found to have better legibility of Arabic handwriting and lesser frequency of spelling mistakes. Also, they showed more frequent use of punctuation marks. On the other hand, handwriting of subjects whose primary language of education was English language showed greater frequency of keeping regular word spacing. Subjects who were practicing drawing were found to keep regular right and left margins, regular spacing between lines and good legibility of handwriting. Conclusions: Both of primary language of education and drawing practice was found to affect Arabic handwriting while the effect of genetic factor couldn’t be evidenced.
