On the need for low-carbon and sustainable computing and the path towards zero-carbon computing. See https://wimvanderbauwhede.github.io/articles/frugal-computing/ for the complete article with references. * The problem: The current emissions from computing are about 2% of the world total but are projected to rise steeply over the next two decades. By 2040 emissions from computing alone will be close to 80% of the emissions level acceptable to keep global warming below the safe limit of 1.5°C. This growth in computing emissions is unsustainable: it would make it virtually impossible to meet the emissions warming limit. The emissions from production of computing devices far exceed the emissions from operating them, so even if devices are more energy efficient producing more of them will make the emissions problem worse. Therefore we must extend the useful life of our computing devices. * The solution: As a society we need to start treating computational resources as finite and precious, to be utilised only when necessary, and as effectively as possible. We need frugal computing: achieving the same results for less energy. * The vision: Imagine we can extend the useful life of our devices and even increase their capabilities without any increase in energy consumption. Meanwhile, we will develop the technologies for the next generation of devices, designed for energy efficiency as well as long life. Every subsequent cycle will last longer, until finally the world will have computing resources that last forever and hardly use any energy. NOTE: there is a small mistake in the presentation, the safe limit for 2040 is 13 GtCO2e, not 23. This makes it even more important to embrace frugal computing.

Many people working in academia find it difficult to achieve or maintain a good work-life balance. This talk goes into the reasons for this, the consequences of working too much, the benefits of having the right balance, and ways of achieving a better balance. The talk is very much based on my personal views and experiences, but I hope there is some interest in sharing these.

This talk is about two Perl modules (Call:Haskell and Functional::Types) I developed to call Haskell functions as transparently as possible. In general, the only way to guarantee the correctness of the types of the function arguments in Haskell is to ensure they are well-typed in Perl. So I ended up writing a Haskell-inspired type system for Perl. In this talk I will first discuss the approach I took to call Haskell from Perl, and then the reasons why a type system is needed, and the actual type system I developed. The type system is based on "prototypes", functions that create type descriptors, and a small API of functions to create type constructors and manipulate the types. The system is type checked at run time and supports sum types, product types, function types and polymorphism. The approach is not Perl-specific and suitable for other dynamic languages. https://github.com/wimvanderbauwhede

Context. WASP-76 b has been a recurrent subject of study since the detection of a signature in high-resolution transit spectroscopy data indicating an asymmetry between the two limbs of the planet. The existence of this asymmetric signature has been confirmed by multiple studies, but its physical origin is still under debate. In addition, it contrasts with the absence of asymmetry reported in the infrared (IR) phase curve. Aims. We provide a more comprehensive dataset of WASP-76 b with the goal of drawing a complete view of the physical processes at work in this atmosphere. In particular, we attempt to reconcile visible high-resolution transit spectroscopy data and IR broadband phase curves. Methods. We gathered 3 phase curves, 20 occultations, and 6 transits for WASP-76 b in the visible with the CHEOPS space telescope. We also report the analysis of three unpublished sectors observed by the TESS space telescope (also in the visible), which represents 34 phase curves. Results. WASP-76 b displays an occultation of 260±11 and 152±10 ppm in TESS and CHEOPS bandpasses respectively. Depending on the composition assumed for the atmosphere and the data reduction used for the IR data, we derived geometric albedo estimates that range from 0.05 ± 0.023 to 0.146 ± 0.013 and from <0.13 to 0.189 ± 0.017 in the CHEOPS and TESS bandpasses, respectively. As expected from the IR phase curves, a low-order model of the phase curves does not yield any detectable asymmetry in the visible either. However, an empirical model allowing for sharper phase curve variations offers a hint of a flux excess before the occultation, with an amplitude of ∼40 ppm, an orbital offset of ∼−30◦ , and a width of ∼20◦ . We also constrained the orbital eccentricity of WASP-76 b to a value lower than 0.0067, with a 99.7% confidence level. This result contradicts earlier proposed scenarios aimed at explaining the asymmetry observed in high-resolution transit spectroscopy. Conclusions. In light of these findings, we hypothesise that WASP-76 b could have night-side clouds that extend predominantly towards its eastern limb. At this limb, the clouds would be associated with spherical droplets or spherically shaped aerosols of an unknown species, which would be responsible for a glory effect in the visible phase curves.

Chemistry is the scientific study of matter, its properties, composition, structure, and the changes it undergoes. It's often divided into various sub-disciplines such as organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, and biochemistry. Chemistry plays a crucial role in understanding the world around us and has applications in various fields such as medicine, materials science, environmental science, and industry.

Theoretical predictions and observational data indicate a class of sub-Neptune exoplanets may have water-rich interiors covered by hydrogen-dominated atmospheres. Provided suitable climate conditions, such planets could host surface liquid oceans. Motivated by recent JWST observations of K2-18 b, we self-consistently model the photochemistry and potential detectability of biogenic sulfur gases in the atmospheres of temperate sub-Neptune waterworlds for the first time. On Earth today, organic sulfur compounds produced by marine biota are rapidly destroyed by photochemical processes before they can accumulate to significant levels. Domagal-Goldman et al. suggest that detectable biogenic sulfur signatures could emerge in Archean-like atmospheres with higher biological production or low UV flux. In this study, we explore biogenic sulfur across a wide range of biological fluxes and stellar UV environments. Critically, the main photochemical sinks are absent on the nightside of tidally locked planets. To address this, we further perform experiments with a 3D general circulation model and a 2D photochemical model (VULCAN 2D) to simulate the global distribution of biogenic gases to investigate their terminator concentrations as seen via transmission spectroscopy. Our models indicate that biogenic sulfur gases can rise to potentially detectable levels on hydrogen-rich water worlds, but only for enhanced global biosulfur flux (20 times modern Earth’s flux). We find that it is challenging to identify DMS at 3.4 μm where it strongly overlaps with CH4, whereas it is more plausible to detect DMS and companion byproducts, ethylene (C2H4) and ethane (C2H6), in the mid-infrared between 9 and 13 μm.

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.

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.

Why I do Computing Science Research
1.
School of Compu,ng
Science Why I do CS Research 25 April 2014 Wim Vanderbauwhede
2.
I want to
talk about
3.
fiction
4.
(and CS).
5.
Iain Banks, Scottish writer, died
last year.
6.
He created “the Culture”.
7.
In the Culture,
8.
sentient machines run everything, everyone
has everything and everything is free.
9.
Banks envisaged that the
society of the Culture came about through
10.
the sheer availability of
information and computing power.
11.
In other words,
12.
in Banks’s vision,
13.
CS created
14.
Utopia.
15.
16.
Back in the present
…
17.
CS luckily still
has some unsolved questions ...
18.
of some problems
for your specialism
19.
• In my area,
e.g. exploiting parallelism and heterogeneous systems for energy-efficient computing. • So we need new languages, compilers, architectures, etc.
20.
21.
Back in the real
world …
22.
there are many problems:
23.
24.
• climate change • aging population • energy
security • the internet is broken
25.
• climate change • aging population • energy
security • the internet is broken
26.
I want to
think of ways of using my research to help address some of those problems.
27.
• e.g. helping weather
scientists to improve prediction of severe weather events. • or linking rainfall predictions to flooding simulations
28.
29.
That way, I
feel I’m part of the
30.
solution.
31.
Thank you!
