The threat of patent infringement to businesses is perhaps better known in industries such as pharmaceuticals, engineering and manufacturing. However, in the User Experience (UX) field there are potential issues around patent infringement that, as practitioners, we need to be aware of. This session (originally a discussion held at UX Cambridge 2014) aimed to increase awareness and start a discussion amongst UX professionals regarding intellectual property issues that may impact our work. The session was an open discussion, where participants shared their experiences and concerns and posed questions for further exploration. The outcome was a sketchnote (https://www.flickr.com/photos/97823772@N02/15058945187/in/set-72157647610886191) which summarised the discussion. This was created by Chris Spalton, https://twitter.com/ChrisSpalton) [Please note: we are not intellectual property legal experts. Examples are from our own experience in this area, and secondary research sources. The main aim was to start a conversation and to identify the gaps in our knowledge in this potentially important area.]

Free talk video (you just need to get the access code by email) is here: https://www.iscb.org/cms_addon/multimedia/flvmedia.php?i=1377 Presented at ISMB ECCB 2013 conference: http://www.iscb.org/ismbeccb2013 It is recognised that bioinformatics resources often suffer from usability problems: for example, they can be too complex for the infrequent user to navigate, and they can “lack sophistication” compared to other websites that people use in their daily lives. In this presentation, Dr. Jenny Cham, User-Experience Analyst at the European Bioinformatics Institute, UK, will describe specific case studies to show how user-centred design (UCD) principles can be applied to bioinformatics services. As well as improved usability, the benefits of UCD can include more effective decision-making for design ideas and technologies during development; enhanced team-working and communication; cost effectiveness; and ultimately a bioinformatics service that more closely meets the needs of its target research community.

Tutorial: As a UX practitioner working in complex environments you have to be flexible, since commonly-used user-centred design techniques may not work. In this tutorial, we provide insights into how you can approach UX problems in complex fields with confidence. With concrete examples from our experience of designing services for life scientists, we describe approaches you can use to characterise specialist users, and translate their requirements into successful designs. In the hands-on activity, you will experiment with our unique (and recently published) ‘canvas sort’ technique, for prioritising large numbers of data items and modelling their interactions. So if you work in UX in a complex environment - such as in scientific research, pharmaceuticals, engineering, technology, finance, or others - join us to learn how to survive when things get complicated!

A Survival Guide for Complex UX

Developing new medicines is an extremely challenging process with more than 50% of new medicines failing in late-stage development where the cost is the greatest. One of the main reasons for attrition is insufficient knowledge about the nature of the gene or protein (target) involved in a disease. Scientists in pharmaceutical research and development use diverse data and software applications to aid decision-making for drug target identification and validation. We have been designing a new web portal to support researchers working within the pharmaceutical industry and academic organisations with the aim to make early drug target identification more efficient. We will report on how we applied a range of participatory design methods including interviews, observations, sketching workshops, paper prototyping and usability testing to understand how experts carry out the very early stages of drug discovery. We will discuss the challenges of working in this domain and the extent to which standard UX approaches helped us understand what matters for our potential users so we could design and deliver solutions within an Agile framework. We also mention when popular UX methods didn't work in this complex environment and how we addressed these issues. This work has been carried out via the Centre for Therapeutic Target Validation, a partnership between the European Bioinformatics Institute, the Wellcome Trust Sanger Institute and GlaxoSmithKline.

Tips for Workshop Facilitation

Storytelling is an important medium in our culture and often takes the form of folktales and myths. Humans are hardwired to listen and learn from stories, and as children, our first forays into the world of literature are through picture-books. We are also all born with the ability to communicate visually, and drawing has been shown to develop along the same pathways as language therefore developing this is simply a matter of learning and practice. The purpose of this tutorial is to offer attendees a space to explore and develop their visual thinking, sketching and note-taking skills whilst obtaining constructive feedback from the tutors. Those attending will leave the tutorial with the confidence to engage actively with sketching on a day to day basis. Attendees will be encouraged to apply what they have learnt to their current research or employment. The half day tutorial will take place on Monday 24 October at NordiCHI’2016, Gothenburg Sweden. It will offer attendees a space to learn and practice visual thinking and sketching https://sketchinghci.wordpress.com/

User Experience 6: Qualitative Methods, Playtesting and Interviews

People doing usability testing often display video of the test participant in a small picture-in-picture window in the corner of the screen. Theoretically this increases observer empathy and helps convince even the most stubborn executive that their product makes users miserable—and needs fixing. After years of teaching people to do usability testing, I’ve come to feel that showing observers the participant's face may not always be a good thing. In this presentation, I spell out the pros and cons of using picture-in-picture video. Slides by Steve Krug, author of Don’t Make Me Think. Presented at the UXPA Boston Conference, May 19, 2017.

This was a 4-hour workshop that was given at World Usability Day Colombia. #wudco14 Summary: Now more than ever is the survival of the easiest. Whether the product is a website or a handheld device, success depends largely on how easy it is to use. Usability testing is one of the most effective for creating an intuitive methods. By observing actual people when they use the product, you can get valuable insights if your design is easy to use. Attendees will learn how to conduct a usability test with end users of a product. This workshop is highly interactive and includes several practical exercises to give participants practical experience. You will learn: - How to plan a usability testing study - How to define the goals and objectives - Explore options (unmoderated usability testing vs. unmoderated & remote vs. in-person) - How to recruit the right participants - How to create tasks (Interview-based vs. predefined tasks) - How to moderate a usability test - How to analyze and report the results

Typical research methodologies in SoTL include many of the traditional educational research methodologies, yet there are methodologies in other disciplines and industries that can provide fresh perspectives. One of these industries is the videogame industry. While there are fundamental differences such as the fact that one seeks primarily to entertain and the other to enlighten or educate, the practices, processes, and theories behind playtesting games can be used to inform aspects of pedagogy that relate to engagement. The primary focus in game design is on the experience and there has been considerable research into ways to assess and measure the player experience through playtesting. Playtesting is concerned with such things as whether or not the game is fun, which parts are too easy or hard, whether and when people become bored, and with the player’s progression through the to the end. All of these properties have relevance to teaching and learning even though they may not appear to be directly connected with whether or not the learning objectives were met. Rather, playtesting is concerned with the motivation of the player/student to continue the particular course of learning, which speaks to the success of the methodology in capturing the student's imagination. Sometimes, simply taking a novel approach to evaluation can yield insights that were not uncovered by more common approaches. This presentation will provide a brief overview of formal playtesting procedures and highlight ways these approaches could be used in the classroom as well as how this could inform pedagogy.

Interviewing is undeniably one of the most valuable and commonly used user research tools. Yet it's often not used well, because * It’s based on skills we think we have (talking or even listening) * It's not taught or reflected on, and * People tend to "wing it" rather than develop their skills. Results may be inaccurate or reveal nothing new, suggesting the wrong design or business responses, or they may miss the crucial nuance that points to innovative breakthrough opportunities. In this day-long session, we'll focus on the importance of rapport-building and listening and look at techniques for both. We will review different types of questions, and why you need to have a range of question types. This session will explore other contextual research methods that can be built on top of interviewing in a seamless way. We'll also suggest practice exercises for improving your own interviewing skills and how to engage others in your organization successfully in the interviewing experience.

Interviewing Users: Spinning Data Into Gold

Steve Portigal

While we know, from a very young age, how to ask questions, the skill of getting the right information from users is surprisingly complex and nuanced. This session will focus on getting past the obvious shallow information into the deeper, more subtle, yet crucial, insights. If you are going to the effort to meet with users in order to improve your designs, it's essential that you know how to get the best information and not leave insights behind. Being great in "field work" involves understanding and accepting your interviewee's world view, and being open to what they need to tell you (in addition to what you already know you want to learn). We'll focus on the importance of rapport-building and listening and look at techniques for both. We will review different types of questions, and why you need to have a range of question types. This session will explore other contextual research methods that can be built on top of interviewing in a seamless way. We'll also suggest practice exercises for improving your own interviewing skills and how to engage others in your organization successfully in the interviewing experience.

Wepresent Atacama Large Millimeter/submillimeter Array 12-m, 7-m, and Total Power Array observations of the FUOrionis outbursting system, covering spatial scales ranging from 160 to 25,000 au. The high-resolution interferometric data reveal an elongated 12CO(2–1) feature previously observed at lower resolution in 12CO(3–2). Kinematic modeling indicates that this feature can be interpreted as an accretion streamer feeding the binary system. The mass infall rate provided by the streamer is significantly lower than the typical stellar accretion rates (even in quiescent states), suggesting that this streamer alone is not massive enough to sustain the enhanced accretion rates characteristic of the outbursting class prototype. The observed streamer may not be directly linked to the current outburst, but rather a remnant of a previous, more massive streamer that may have contributed enough to the disk mass to render it unstable and trigger the FU Orionis outburst. The new data detect, for the first time, a vast, slow-moving carbon monoxide molecular outflow emerging from this object. To accurately assess the outflow properties (mass, momentum, and kinetic energy), we employ 13CO(2–1) data to correct for optical depth effects. The analysis indicates that the outflow corresponds to swept-up material not associated with the current outburst, similar to the slow molecular outflows observed around other FUor and Class I protostellar objects.

We explore different scenarios to explain the chemical difference found in the remarkable giant-giant binary system HD138202+CD−3012303. For the first time, we suggest how to distinguish these scenarios by taking advantage of the extensive convective envelopes of giant stars. Methods. We carried out a high-precision determination of stellar parameters and abundances by applying a full line-by-line differential analysis on GHOST high-resolution spectra. We used the FUNDPAR program with ATLAS12 model atmospheres and specific opacities calculated for an arbitrary composition through a doubly iterated method. Physical parameters were estimated with the isochrones package and evolutionary tracks were calculated via MIST models. Results. We found a significant chemical difference between the two stars (∆[Fe/H]∼0.08dex), which is largely unexpected considering the insensitivity of giant stars to planetary ingestion and diffusion effects. We tested the possibility of engulfment events by using several different combinations of stellar mass, ingested mass, metallicity of the engulfed object and different convective envelopes. However, the planetary ingestion scenario does not seem to explain the observed differences. For the first time, we distinguished the source of chemical differences using a giant-giant binary system. By ruling out other possible scenarios such as planet formation and evolutionary effects between the two stars, we suggest that primordial inhomogeneities might explain the observed differences. This remarkable result implies that the metallicity differences that were observed in at least some main-sequence binary systems might be related to primordial inhomogeneities rather than engulfment events. We also discuss the important implications of finding primordial inhomogeneities, which affect chemical tagging and other fields such as planet formation. We strongly encourage the use of giantgiant pairs. They are a relevant complement to main-sequence pairs for determining the origin of the observed chemical differences in multiple systems.

Mustard, as a crop, is susceptible to a variety of pests that can affect its growth and yield. Here’s a rundown of some common pests that target mustard plants: Aphids: These small, sap-sucking insects can cause significant damage by feeding on the leaves and stems. Aphids also excrete a sticky substance known as honeydew, which can lead to the growth of sooty mold on the plants. Flea Beetles: These tiny beetles jump like fleas when disturbed and chew small holes in the leaves. They are particularly damaging in the early growth stages of the plant. Cabbage Loopers: The larvae of a type of moth, these caterpillars are known for their distinctive looping movement. They chew large holes in the leaves and can defoliate plants if present in large numbers. Diamondback Moth Larvae: Another caterpillar pest, these larvae chew small holes in the leaves and can cause extensive damage, especially when infestations are heavy. Whiteflies: These are tiny, winged insects that feed on plant sap and can quickly become a problem in greenhouse or close planting conditions. Like aphids, they also secrete honeydew. Cutworms: These are the larvae of certain types of moths and are known for cutting young plants at the stem base at ground level. They are most destructive during the night. Root Maggots: The larvae of root maggot flies, these pests attack the roots of mustard plants, causing wilting and potentially killing young plants. Harlequin Bugs: These are colorful stink bugs that suck the sap from mustard plant stems and leaves, causing the leaves to become stippled, wilt, and eventually die if the infestation is severe. Mustard Sawfly: The larvae of the mustard sawfly can cause considerable defoliation, as they feed voraciously on the leaves. Clubroot: Caused by a fungus-like organism, clubroot affects the roots, causing them to swell and distort. While technically a disease, it is often associated with pest management because controlling it involves similar preventative strategies. Control Measures: Managing pests in mustard involves a combination of cultural, biological, and chemical methods. Crop rotation, resistant varieties, timely sowing, maintaining plant health, and using natural predators like ladybugs and parasitic wasps can help keep pest populations under control. Chemical pesticides should be used as a last resort due to their potential impact on the environment and non-target species.

HotJupiters are amongthebest-studied exoplanets, but it is still poorly understood how their chemical composition and cloud properties vary with longitude. Theoretical models predict that clouds may condense on the nightside and that molecular abundances can be driven out of equilibrium by zonal winds. Here we report a phase-resolved emission spectrum of the hot Jupiter WASP-43b measured from 5–12µ 5–12µ 5–12µm with JWST’s Mid-Infrared Instrument (MIRI). 1524 ±35 1524 ±35 and 863±23 The spectra reveal a large day–night temperature contrast (with average brightness temperatures of 1524 ± 35 863 ±23 863 ±23Kelvin, respectively) and evidence for water absorption at all orbital phases. Comparisons with three-dimensional atmospheric models show that both the phase curve shape and emission spectra strongly suggest the presence of nightside clouds which become optically thick to thermal emission at pressures greater than ∼100mbar. The dayside is consistent with a cloudless atmosphere above the mid-infrared photosphere. Con3trary to expectations from equilibrium chemistry but consistent with disequilibrium kinetics models, methane is not detected on the nightside (2σ upper limit of 1–6 parts per million, depending on model assumptions).

Botany is the branch of biology that deals with the scientific study of plants, including their structure, growth, reproduction, metabolism, development, and classification. It encompasses a wide range of topics, from the molecular biology of plant cells to the ecological relationships between plants and their environments. Botany is essential for understanding plant diversity, ecology, evolution, and the roles plants play in ecosystems and human societies.

Bollworms are among the most damaging pests in cotton cultivation, affecting the bolls where the cotton fibers are formed. There are several species of bollworms, each capable of causing significant yield loss and quality degradation if not effectively managed. Here’s a detailed look at the primary bollworm species affecting cotton: Cotton Bollworm (Helicoverpa armigera): Also known as the corn earworm or the Old World bollworm, this pest is found in many regions around the world. It is highly polyphagous (feeds on many different plants) and poses a threat not only to cotton but also to maize, tomatoes, and legumes. The larvae bore into the cotton bolls, feeding on the developing seeds and fibers, which can lead to boll rot. Pink Bollworm (Pectinophora gossypiella): A significant pest of cotton, the pink bollworm larvae infest the cotton bolls, feeding on the seeds and lint. This can severely damage or destroy the bolls. In regions where pink bollworms are prevalent, they have been a major driver for the adoption of genetically engineered Bt cotton, which expresses a bacterium gene toxic to certain insects. Tobacco Budworm (Heliothis virescens): Closely related to the cotton bollworm, the tobacco budworm primarily attacks tobacco but is also a common pest in cotton. It primarily damages the flowers and bolls of the cotton plant. Differentiating between the tobacco budworm and the cotton bollworm based on appearance can be challenging, but it is crucial for effective management. American Bollworm (Helicoverpa zea): Known in some regions as the corn earworm, it is similar in behavior to Helicoverpa armigera and poses a threat to a variety of crops, including cotton. The larvae attack the cotton bolls, leading to direct damage to the cotton lint and seeds. Management Strategies: Cultural Controls: Crop rotation, destruction of crop residues, and deep plowing can help break the pest’s life cycle. Timing of planting can also be adjusted to avoid peak pest infestation. Biological Controls: Natural enemies like Trichogramma wasps, which parasitize bollworm eggs, and predators such as lacewings and ladybugs can be encouraged. Bacillus thuringiensis (Bt) products can also be sprayed, which are particularly effective against young larvae. Chemical Controls: Insecticides may be required when infestation levels exceed economic thresholds. However, resistance management must be considered, alternating modes of action to avoid developing resistance. Genetic Approaches: Bt cotton, genetically modified to express Bacillus thuringiensis toxin, has been highly effective in controlling bollworms and has dramatically reduced the reliance on chemical insecticides. Monitoring and Scouting: Regular field scouting and using pheromone traps to monitor adult populations can help in timely and targeted application of control measures. The effective management of bollworms often requires an integrated approach

Understanding circumstellar disks is of prime importance in astrophysics, however, their birth process remains poorly constrained due to observational and numerical challenges. Recent numerical works have shown that the small-scale physics, often wrapped into a sub-grid model, play a crucial role in disk formation and evolution. This calls for a combined approach in which both the protostar and circumstellar disk are studied in concert. Aims. We aim to elucidate the small scale physics and constrain sub-grid parameters commonly chosen in the literature by resolving the star-disk interaction. Methods. We carry out a set of very high resolution 3D radiative-hydrodynamics simulations that self-consistently describe the collapse of a turbulent dense molecular cloud core to stellar densities. We study the birth of the protostar, the circumstellar disk, and its early evolution (< 6 yr after protostellar formation). Results. Following the second gravitational collapse, the nascent protostar quickly reaches breakup velocity and sheds its surface material, thus forming a hot (∼ 103 K), dense, and highly flared circumstellar disk. The protostar is embedded within the disk, such that material can flow without crossing any shock fronts. The circumstellar disk mass quickly exceeds that of the protostar, and its kinematics are dominated by self-gravity. Accretion onto the disk is highly anisotropic, and accretion onto the protostar mainly occurs through material that slides on the disk surface. The polar mass flux is negligible in comparison. The radiative behavior also displays a strong anisotropy, as the polar accretion shock is shown to be supercritical whereas its equatorial counterpart is subcritical. We also f ind a remarkable convergence of our results with respect to initial conditions. Conclusions. These results reveal the structure and kinematics in the smallest spatial scales relevant to protostellar and circumstellar disk evolution. They can be used to describe accretion onto regions commonly described by sub-grid models in simulations studying larger scale physics.

A botany file is similar to a chemistry practical file but specifically focuses on experiments and observations related to plants. It typically includes detailed descriptions of plant-related experiments, such as germination studies, growth experiments, tissue culture techniques, plant anatomy investigations, and ecological surveys. The file may contain records of plant specimens collected, their classification, characteristics, and ecological significance. Additionally, it may include diagrams, photographs, drawings, tables, and data analysis related to plant research. Like a chemistry practical file, a botany file serves as a documentation of practical work conducted in the field of botany and is often used for assessment and educational purposes.

How to run 1-to-1 usability testing (with life scientists)

1. Analysing the EBI User Experience29.07.20161 Why didn’t you click on the obvious one ? Jenny Cham User Experience (UX) Analyst So why did you click there ?

2. Analysing the EBI User Experience29.07.2016 17 sites >70 scientists May to Oct Example of usability testing

3. 3 Design changes to interface design Judgment calls Group decision Usability testing Analysis

4. Benefits Obvious Discover unknown/unexpected problems Video footage as ‘proof’/objectivity (dilemmas get sorted) Cheap and quick, fix early e.g. during agile 29.07.20164 Not so obvious… Easy to use software = warm fuzzy feelings Awareness of the new software with participants Which features are not necessary? Records progress

5. Analysing the EBI User Experience Don’t call it testing Get their boss or local contact person to send named invite around Incentives + lunch Formal and informal – credibility but not too daunting Try to recruit for your personas – use a ‘screener’

6. 29.07.20166 6 Persona: Debra, Drug Discovery What is the reaction chemistry? Are there any known genes? etc… Is he is a ‘Debra’? (SurveyMonkey.net)

7. Plenty of buffer time esp. if a website3 or so sessions is plenty/day Ideally 30 min turnaround for analysis time Schmooze with management, let them have a go too Go to the users’ site

8. Analysing the EBI User Experience 29.07.201 8 Get the user to read ALOUD Pick scenarios as relevant as possible: pre-test screenerSeveral to do same one if poss

9. Love thy user We are not testing you Outline the plan clearly You can leave at any timeThere is no such thing as ‘wrong’ We really value your input Do you have any questions? No, we won’t put the video on YouTube

10. Analysing the EBI User Experience 29.07.201 10 Supersticky post-its, different colours Decent wall space for analysis Nice drinks Laptop height & set up mouse for left/right handed Facilitator – say as little as you can (cringe) Consent form for video Quiet room Grid to fill in notes Get user’s background info on tape (1st few mins)

11. http://silverbackapp.com/

12. Takes preparation - each screen layout ready Have blanks for ‘under construction’/ user sketches Avoid users with a software dev. background End the test early if it’s going no where

13. The user says… Over to you….(think therapist!) I want to find the contact details so should I go here? Where do you think it should go? …(silence)… What are you thinking now? Oooh…I didn’t expect that What did you expect to happen?

14. Obvious May need to sell the idea to management – suggest doing it ‘guerrilla’ style anyway Dependent on the sample, not statistically significant Doesn’t tell you how to fix issues Not so obvious Developers think you are giving them extra work You will want to test everything! Drawbacks/ challenges

15. Analysing the EBI User Experience 29.07.201 15 Usability testing would be great for our project And ours… Now have a go yourself…

16. 29.07.201 16 Thanks for listening The end
