Increasing Female Middle School Student Interest in STEM: Requirements for Game-Based Learning Applications*

This exploratory work developed requirements to build games to increase female middle school students’ interest in Science, Technology, Engineering, and Mathematics (STEM). In middle school, students typically begin to determine career interests. Female students have many barriers to full participation in STEM, including stereotypes, role socialization, interests, and attitudes which can influence confidence in areas such as mathematics. Game-Based approaches are designed to overcome barriers, allow experimentation with difficult concepts, and engage students. However, many games are designed for the ‘‘default’’ male user, leaving female preferences unaddressed or as secondary issue. Six requirements (Protagonist, Mechanics, Socialization, Fun, Uncertainty, and Story) were developed from relevant literature, surveys, and consultation with STEM outreach organizations. The requirements were developed to identify factors which may make a game engaging to a wider audience that include female middle school students. The requirements were used to develop SORCERESS OF SEASONS, a game designed to develop computational literacy in middle school students. An evaluation with 15 middle school students provided feedback on requirements, learning, and STEM interest. Both female and male middle school students showed an increase of basic computational knowledge comprehension, and increased interest in STEM careers, with females reporting a larger gain. The results suggest that the requirements may be helpful when developing games to increase student interest in STEM.
Study of heat transfer in a nanofluid layer using homotopy analysis method

In this paper, we perform a weak nonlinear stability analysis to study the heat transfer in a horizontal nanofluid layer. We consider a set of new boundary conditions for the nanoparticle fraction, which is physically more realistic. The new boundary condition is based on the assumption that the nanoparticle fraction adjusts itself so that the nanoparticle flux is zero on the boundaries. The governing equations for this problem are reduced to Ginzburg–Landau equation and solved by using homotopy analysis method (HAM). Obtained results are valid for the whole solution domain with high accuracy. Nusselt number and Nanoparticle Nusselt number are calculated for different values of parameters. The results have been depicted graphically. Publication Info
Is Tramadol an Opioid or a Nonopioid Analgesic? Yes!

I was sitting in a national conference a few years ago when a prominent pharmacist stood up to speak and talked about the ravages of prescription opioids in the United States. He stated that if anyone in his family ever needed pain medications he would never allow them to have opioids. “They would get Tylenol, Toradol and Tramadol”. I was shocked that this respected clinical pharmacologist thought that tramadol was not an opioid. He is not alone. When discussing the dangers of opioids, the tramadol “nonopioid” alternative comes up again and again with students, colleagues and even authors in highly respected medical journals 1, 2, 3. Tramadol is now available in more than 100 countries and is the most commonly prescribed opioid worldwide 4. In the US, tramadol prescriptions more than doubled between 2007 and 2015, becoming the second most prescribed opioid. Is it possible that the primary care, and particularly nonphysician, prescribers 5 responsible for the increase in tramadol prescribing in the midst of the “opioid epidemic” are prescribing more tramadol because they don’t think tramadol is an opioid? If so, it is important to note that data on opioid use after surgery 6 shows that tramadol is at least as likely as other opioids to be continued long-term; a surrogate measure 7 for abuse and overdose. Indeed, according to the Drug Abuse Warning Network, there was a 250% increase in emergency department visits involving misuse or abuse of tramadol between 2005 and 2011 8. In this article I will look at the pharmacology of tramadol with an emphasis on distinguishing its opioid and nonopioid properties.
Sweet love: The effects of sweet taste experience on romantic perceptions

Terms of endearment such as ‘‘sweetie,’’ ‘‘honey,’’ and ‘‘sugar’’ are commonly used in the context of describing romantic partners. This article explores how a relatively subtle manipulation, namely taste sensations, might influence romantic perceptions of a nonestablished relationship. Consistent with predictions, results from Studies 1 and 2 (n 1⁄4 280) showed that participants evaluated a hypothetical relationship, but not an existing relationship, more favorably when exposed to sweet taste compared to nonsweet taste control. Study 3 (n1⁄4 142) further showed that participants indicated greater interest in initiating a relationship with a potential partner when exposed to sweet taste, as compared to control participants. Implications for the role of sweet taste experiences in attraction and relationship initiation are discussed.
How (Not) to Exclude Outliers: Within-Conditions Exclusions Lead to Dramatic Increases in False-Positive Rates WORKING PAPER – PLEASE DO NOT CITE OR DISTRIBUTE WITHOUT THE AUTHOR’S APPROVAL

When researchers choose to identify and exclude outliers from their data, should they do so across all the data, or within experimental conditions? A survey of recent papers published in the Journal of Experimental Psychology: General shows that both methods are widely used, and common data visualization techniques suggest that outliers should be excluded at the conditionlevel. However, I highlight in the present paper that removing outliers by condition runs against the logic of hypothesis testing, and that this practice leads to unacceptable increases in falsepositive rates. I demonstrate that this conclusion holds true across a variety of statistical tests, exclusion criterion and cutoffs, sample sizes, and data types, and show in simulated experiments that Type I error rates can be as high as 29%. I then replicate this result in the context of a recent paper excluding outliers per condition (Cao, Kong, and Galinsky, 2020). Using the authors’ original data, I show that excluding outliers at the condition level can bring the likelihood of a false-positive result up to 47%, and demonstrate that the exclusion strategy reported by the authors is associated with a 56% Type I error rate. I conclude with a list of alternatives to withincondition exclusions.
CRYPTOGRAPHIC KEY GENERATION FROM MULTIMODAL BIOMETRICS USING MIPT METHOD

Cryptography is often used in an information technology security environment to protect data that is sensitive, has a high value, or is vulnerable to unauthorised disclosure or undetected modification during transmission or while in storage. Cryptography relies upon two basic components: an algorithm (or cryptographic methodology) and a cryptographic key. This Recommendation discusses the generation of the keys to be managed and used by the approved cryptographic algorithms. This paper proposed first approach method Minutiae points from fingerprint using Image Processing and Texture features from iris (MIPT) for cryptographic key generation from multimodal biometrics, extraction of Minutiae points from fingerprint using Image Processing, extraction of Texture features from Iris, feature level fusion of fingerprint and iris features. Simulation and experimental results are verified using MATLAB/Simulink platform. Index Terms Biometric systems, CSLF, Cryptography key generation, MIPT.
Control of ethylene synthesis and ripening by sense and antisense genes in transgenic plants

Ripening of tomato and other fruits involves changes in quality attributes that make them attractive to consumers. These alterations are brought about by the coordinated expression of specific genes. Ethylene, synthesised by cells of climacteric fruit at the onset of ripening, stimulates the expression of genes required for ripening to occur. Experiments with transgenic plants have shown that a 5′ flanking region from the fruit polygalacturonase (PG) gene directs the ripening-specific expression of foreign genes in tomato. Antisense genes have also been used to down-regulate expression of the PG gene, causing a reduction in pectin degradation during ripening. This reduction in PG has beneficial effects on fruit storage life and processing characteristics. Antisense technology has also been used to assign functions to previously unknown genes. This has led to the identification of the gene for ethylene forming enzyme (EFE) which catalyses the terminal step in ethylene synthesis. Detached fruit from tomato plants in which EFE is inhibited by antisense genes produce much less ethylene and ripening is greatly slowed. The rate of ripening can be restored by adding ethylene externally. These results raise the possibility of manipulating ripening of many fruits and also of controlling processes such as abscission and senescence of leaves and flowers.
Effects of Salicylic Acid on Germination of Soybean Seed under Chromium Stress

The paper studied the effects of chromium stress on germination of soybean(Glycine max L.)cv.Ribenqing and the meditative effect of SA under hydroponic cultural conditions.The results showed that the germination rate,germination index and vigor index of soybean seed decreased,the MDA content and the relative electrical conductivity of soybean hypocotyls increased with the increase of chromium concentration in range of 0-200 mg·L-1Cr6+. The germination of soybean seed was significantly(P0.01)inhibited when the concentration of chromium was 100 mg·L-1.0. 05 mmol·L-1 SA could alleviate the toxicity of soybean under the chromium stress.
Semantic enrichment of data for AI applications

In this work, we use semantic knowledge sources, such as cross-domain knowledge graphs (KGs) and domain-specific ontologies, to enrich structured data for various AI applications. By enriching our understanding of the underlying data with semantics brought in from external ontologies and KGs, we can better interpret the data as well as the queries to answer more questions, provide more complete answers, and deal with entity disambiguation. To semantically enrich the data with external knowledge sources, we need to find the correspondences between the structured data and the entities in the cross-domain KGs and/or the domain-specific ontologies. In this paper, we break this problem into several steps, and provide detailed solutions for each step. We showcase the practical value of semantic enrichment of data using our proposed techniques in entity disambiguation, natural language querying and conversational interfaces to data, query relaxation, as well as query answering, with promising results.
Digitized Banking Transactions using QR Scanner

- Challan is official form or there kind of document, piece of paperwork, citation etc. It is a way of crediting the money to one's bank account through a form. people are waiting in queue for withdraw and deposit money and taking DD in bank. They need some one’s help for filling the challan if they are less educated. To reduce incidents of failed transactions and transactional errors in ATMs, Mobile banking and POS terminals, need to come up with an application that can be used to enhance digital banking, facilitation of ICT skills. Digitized challan can also be defined as a specific format used for Depositing, Withdrawing and DD payment at a bank. Banking payment technology that uses digitized challan using QR code to identify the user and authorized persons account from a bank account. It based on QR Scanning is the most common code accessing method.In this system weuses a secure factor authentication, in which the QR code scan takes the place of the user at the time it automatically generated the account holder’s number and name of the person. And it shows three main functional processes such as Deposit, Withdraw and DD.
Charger-Surfing: Exploiting a Power Line Side-Channel for Smartphone Information Leakage

Touchscreen-based mobile devices such as smartphones and tablets are used daily by billions of people for productivity and entertainment. This paper uncovers a new security threat posed by a side-channel leakage through the power line, called Charger-Surﬁng, which targets these touchscreen devices. We reveal that while a smartphone is charging, its power trace, which can be measured via the USB charging cable, leaks information about the dynamic content on its screen. This information can be utilized to determine the location on the touchscreen where an animation is played by the mobile OS to indicate, for instance, that a button press has been registered. We develop a portable, low cost power trace collection system for the side-channel construction. This leakage channel is thoroughly evaluated on various smartphones running Android or iOS, equipped with the two most commonly used screen technologies (LCD and OLED). We validate the effectiveness of Charger-Surﬁng by conducting a case study on a passcode unlock screen. Our experiments show that an adversary can exploit Charger-Surﬁng across a wide range of smartphone models to achieve an average accuracy of 98.7% for single button inference, and an average of 95.1% or 92.8% accuracy on the ﬁrst attempt when cracking a victim’s 4-digit or 6-digit passcode, respectively. The inference accuracy increases to 99.3% (4-digit) or 96.9% (6-digit) within ﬁve trials. We further demonstrate the robustness of Charger-Surﬁng in realistic settings and discuss countermeasures against it.
Positive Mental Imagery in the Intervention of Negative Mood: A Randomized Controlled Trial

Background The aim of this study was to explore the intervention effect of positive mental imagery training on college students’ negative emotions in adults with depression trend. Methods A 2 (group: training group, non-training group) and 4 (time: pre-, post-, 1-week follow-up, and 6-week follow-up) mixed design was used in the present study, with the group as between-subjects factor and the time as within-subjects factor. Forty-nine participants with depressive tendency were randomly assigned to either the imagery training group or the non-training group. Except for negative interpretive bias were assessed before and after training, participants’ depression and anxiety symptoms, vividness and likelihood of mental imagery were assessed at all four time points. Results Compared to the pre-training, imagery group reported improvement in depression and trait anxiety scores and the likelihood of positive imagery across subsequent three assessments, and showed the improvement in the vividness of positive imagery at post-training. However, there was no significant between-group difference was found in negative interpretation bias. Conclusions The positive mental imagery training could effectively promote negative emotions and anxiety in adults with depression trend after 1-week training, and the effects of mental imagery could at least last for 6weeks, which provides a choice for self-regulation in daily life and is a promising way of mental health care. Often imagine a positive future, at least to some extent, good for our physical and mental health.
Evaluating chemical descriptors with the loss-data framework

Selecting chemical representations for machine learning models is a challenging task, one which is subject to trial and error. Extended connectivity ﬁngerprints (ECFPs), for example, are a classic featurization technique used widely in the prediction of properties of molecules, which effectively encodes molecular sub-structures in a bit vector. However, it is not obvious when to use vanilla ECFPs instead of alternative featurizations. We propose using recent progress in the ﬁeld of representation learning to evaluate and improve the quality of chemical descriptors. Speciﬁcally, we show that using the loss-data framework with surplus description length and ε sample complexity can provide insight into which descriptors are appropriate for speciﬁc tasks. We ﬁnd that applying simple dimensionality reduction techniques such as UMAP and PCA can improve the quality of ECFP descriptors for certain datasets.
Characterizing cancer initiation by Moran Process

It has been shown that the age incidence of chronic myeloid leukemia can be explained by a one-mutation Moran process model (Michor, Iwasa, and Nowak 2006). Moran process assumes the total number of cells is fixed over time, thus when a cell divides, another cell will be chosen by random to die. This model is in general useful to describe cancer initiation since the total number of pre-cancer cells tends to be stable. Here we implemented Moran process in Rcpp and apllied it to clone expansion of acute myeloid leukemia.
Variation and variety in written Middle Scots ( 1971 ) 1

In this seminal paper, AJA outlined the main dimensions of variability in Older Scots, especially but not only in orthography, and identified what would now be called the variables. As was his wont, he gave an overview of the work done in the subject up to that point in time, and offered the detailed, but unsystematically collected, observations that he had made during his long immersion in the language, often explicitly identifying starting points for future research. The paper is now four decades old, and I will not attempt to list the work that has been done since to fill in many of the gaps that AJA then identified, except to mention A Linguistic Atlas of Older Scots: Phase I, 1380–1500 and A Linguistic Atlas of Late Mediaeval English (online as ‘An electronic version of A Linguistic Atlas of Late Mediaeval English’). Ongoing research at the University of Edinburgh (‘From Inglis to Scots’) will analyse the Scots data from the atlases in the context of the shared history with English. Another important body of work is Anneli Meurman-Solin’s ‘Helsinki Corpus of Older Scots (1450-1700)’ and the many publications drawing upon it (from Meurman-Solin, 1993, onwards), and her ‘Corpus of Scottish Correspondence’ (2007). There are also, of course, many new editions of Older Scots texts with detailed linguistic introductions, many published by the Scottish Text Society (but see also van Buuren ed., 1982); and many detailed linguistic analyses of individual texts and writers (including Farrow, 1997; Jumpertz-Schwab, 1998; Glenn, 2003; Bugaj, 2004), as well as studies of particular linguistic features (including Häcker, 1999; and de Haas, 2011) and genres (Kopaczyk, 2013). This paper was written before AJA published his numbering system for the Older Scots vowels (in ‘How to Pronounce Older Scots’, 1977, 2015). It accordingly suffers from the problems of notation that the numbering system seeks to obviate. AJA here uses the traditional philological symbols, sometimes in a hybrid way as phonemic notation within slash brackets, e.g. /ē/. The indicated pronunciations are mostly those of the vowel system as it stood in late Middle Scots, but occasionally reference is made to earlier and later periods, when the same pronunciation might belong to a different vowel. In particular, Middle Scots vowel 4 is (broadly) ē, but it is also referred to, at an earlier point in time, as ā: “the early fifteenth-century coalescence of the segments /al/, /au/ and certain allophones of /ā/”. However, in this paper ā is mostly vowel 12, the result of this coalescence. I have accordingly added the vowel numbers to the text, as I did when I incorporated part of this paper into the chapter on ‘Orthography’ in ‘A History of Scots to 1700’ (Macafee and †Aitken, 2002: §5). Some important contributions to our knowledge of Older Scots orthography by Veronika Kniezsa (1989, 1997) on the Northern English origins of the i-digraph spellings and the
The Effect of Acupressure on Chronic Low Back Pain among Operating Rooms Nurses

Low back pain is the most common musculoskeletal work-related condition among nurses. Acupressure is the type of complementary medicine frequently used today. Acupressure is a technique that involves pressing with a finger to release endorphins, which causes muscle relaxation and pain relief. This study aimed at determining the effect of acupressure on chronic low back pain among nurses working in the operating rooms. Setting: This study was carried out in the operating rooms (OR) of three departments namely OR (A) for colon surgery, OR (B) for oncology& hepatobiliary surgery. Finally OR (C) for head and neck surgery in Alexandria Main University Hospital. Design: a quasi-experimental design was used. Tools: Interviews scheduled to collect socio-demographic and job characteristics, Million visual analog scale (MVAS), and questionnaire were used for the occupational role. Results: a statistically significant difference in pain severity between the study and control group after 6 weeks of acupressure massage (p < 0.001*) was observed. Concerning the post-test mean score of occupational role in the study group was 19.50± 8.22, while in the control group was 52.33 ±7.42, with a highly statistically significant difference between the two groups at p (0.001*). Conclusion: Acupressure is an effective complementary therapy for reducing occupational low back pain in nurses employed in operating rooms as well as improving their occupational function. Recommendation: educational nursing program about effect and technique of acupressure should be conducted.
THE ABILITY TO STIMULATE PROLIFERATION OF PIPER BETLE L. LEAF

Piper betle L. has been used as a folk medicine, the leaves of the P. betle L. act as a potential source in the treatment of skin wounds. It can be attributed to the phenolic compounds within the ethanolic extract of P. betle L. Fibroblasts play a very important role in supporting wound healing. Acceleration of the wound withdrawal process is is closely related to fibroblast migration and proliferation. However, research on medicinal plants' ability to stimulate proliferation and wound healing and their effects on fibroblasts has not been thoroughly studied. Therefore, we investigated the antibacterial ability and possibility of wound healing of P. betle L. extracts on fibroblasts isolated from umbilical cord stem. Evaluate the antibacterial properties of P. betle L. extract by agar disk diffusion method. Evaluate the ability to stimulate cell proliferation of P. betle L. extract by scratch healing assay on fibroblasts in vitro. The results of this study show that the P. betle L. extracts has good resistance to pathogenic microorganisms including Escherichia coli, Staphylococcus aureus and Salmonella. Studies on the ability to stimulate proliferation showed that extracts at a concentration of 0.06 μL/mL inhibited cell proliferation. The concentration of 0.025 μL/mL stimulates fibroblast proliferation better than concentrations 0.03 μL/mL, 0.02 μL/mL; facilitating the scratch healing process 2.8 times faster than the control group in vitro. Our results show that P. betle L. has great potential in being used as a raw material in the development of drugs of natural origin for the treatment of skin wounds.
Visualization of the electron transfer associated with biochemical reaction process by the ultra-slow muon

The SR experiments on trypsin-BPTI complex are proposed. The proton and electron transfer processes are continuously occurring in a trypsin-BPTI complex and the process induces the local magnetic field. The   would be captured at the negatively charged oxyanion hole close to the reaction center of trypsin. As a control system of the SR experiment, trypsinmonoisopropylphosphoryl (MIP) system is adequate, because there the catalytic reaction is absolutely stopped.
