ARTIFICIAL RETINA USING THIN FILM TRANSISTORS DRIVEN BY WIRELESS POWER SUPPLYManiroop Badam
Artificial retinas have been ardently desired to recover the sight sense for sight-handicapped people. We have verified that an artificial retina using poly-Si TFTs can be driven by wireless power supply. It is confirmed that the irradiated light distribution can be reproduced as the output voltage distribution owing to the parameter optimization of the wireless power supply system.
Metals, however much we need it or admire it , the drawbacks of it has to be considered.( high density, susceptibility to corrosion,availability etc)
Instead planes of carbon fibre composites can be made without using a tiny scrap of metal, if only we can alter its conductivity issues. that is addressed by a research paper , on the basis of which my ppt is based.
I use this ppt. to teach Universal Gravitation to mt high school Physics classes. It's a real time saver, and I think it covers the topic well. Of course I add/augment a lot of stuff as I go along.
When all thermonuclear sources of energy are exhausted a suSciently heavy star will
collapse. Unless fission due to rotation, the radiation of mass, or the blowing off of mass by
radiation, reduce the star's mass to the order of that of the sun, this contraction will continue
indefinitely. In the present paper we study the solutions of the gravitational field equations
which describe this process. In I, general and qualitative arguments are given on the
behavior of the metrical tensor as the contraction progresses: the radius of the star approaches
asymptotically its gravitational radius; light from the surface of the star is progressively
reddened, and can escape over a progressively narrower range of angles. In II, an
analytic solution of the field equations confirming these general arguments is obtained for the
case that the pressure within the star can be neglected. The total time of collapse for an observer
comoving with the stellar matter is finite, and for this idealized case and typical stellar
masses, of the order of a day; an external observer sees the star asymptotically shrinking to
its gravitational radius.
Toxic effects of heavy metals : Lead and Arsenicsanjana502982
Heavy metals are naturally occuring metallic chemical elements that have relatively high density, and are toxic at even low concentrations. All toxic metals are termed as heavy metals irrespective of their atomic mass and density, eg. arsenic, lead, mercury, cadmium, thallium, chromium, etc.

The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
2. Pendulum in Latin means hanging
Something hanging from a fixed point which,
when pulled back and released, is free to swing
down by force of gravity and then out and up
because of its inertia.
Inertia: means that bodies in motion, will stay in
motion; bodies at rest, will stay at rest, unless
acted on by an outside force.
3. it can be used to provide accurate
it can be used to measure (the
acceleration due to gravity) which is
important in determining the shape of the
earth and the distribution of materials
within it (the science of geodesy)
And also it can be used to show that
4. Like the earth was flat. many theories came
up from scientists like Copernicus
,Aristarchus etc but they were termed as
“nuts”
then there was Newton's inertia and stuff,
which induced ideas in dynamic men of that
age :P
5. The pendulum has long been a favorite
instrument for measuring the acceleration of
gravity
But the determination of “g” suffers from
complications , if we want high precision.
Such as , when the length of a pendulum
increases, it is increasingly susceptible to
noises, both from surrounding air and also
from the support which is never completely
inertial.
6. “Compound
pendulum” eh??
As we try to modify simple pendulum, to
improve its performance ,it becomes
compound!!!!
Consider an extended body of mass with a hole drilled though it.
Suppose that the body is suspended from a fixed peg,
which passes through the hole, such that it is free to swing from side to side,
This setup is known as a compound pendulum.
8. Suppose p is the pivot axis of the compound
pendulum and G is the centre of gravity.
Its moment of inertia I about an axis through G
parallel to p is I=mk2 , where m is the pendulum’s
mass and k is radius of gyration.
By the parallel axis theorem ,the moment of inertia
about p is I+mL2
The period of oscillation about p is given by
T2=4Π2(I+mL2)/Lgm
T2=4Π2(k2+L2)/Lg
9. Kater’s pendulum is a compound pendulum, in
which the pendulum's centre of gravity don't have
to be determined, allowing greater accuracy.
10. Kater knew that for the pendulum equation to be
precise he needed to know the pendulum’s I. This
amounts to the knowledge of radius of gyration. it is
this radius that is hard to measure precisely since it
depends on the distribution of the mass in the
pendulum. so Kater decided to build a reversible
pendulum.
It has pivots on each end ,with two movable masses
.They are in line the with centre of mass. The value of
the period of oscillation is different in both the ends
.if the movable weight is adjusted until the periods
for both orientations of pendulum becomes equal, we
get our special result “g”
When this case gets satisfied ,Kater's pendulum
becomes equivalent to a simple pendulum.
11. Applying formula for period of motion at both
the pivots and comparing it ,we get
4Π2/g=1/2[ (Ta2 + Tb2)/La+Lb +(Ta2-Tb2)/ La –Lb]
This equation is called Bessel's equation.
if Ta and Tb are nearly equal ,the approximate value of La- Lb
can be considered.
if Ta=Tb, then
g=4Π2 L /T2
12. Keep the knife edges at a distance L cm apart;
Keep the bob say d=5 cm apart from the
knife edges.Suspend the pendulum along ka,
note down the period of oscillation Ta , lll’y
for Tb.
Repeat the experiment for d=10, plot the
graph of time Ta and Tb against d.the
intercept on the abcissa is do.
13. Now keep the distance d=do between bob
and nearest knife edge.
Find Ta and Tb for 100 oscillations about ka
and kb.
Find the centre of gravity of the pendulum
La +Lb =L; and La is the distance from cog to
ka and Lb is the distance from cog to kb.
Find g using the formula .
14. Part -3
Keep the distance btw bob and knife edge as
d=do(+/- )0.5
Note down Ta and Tb ,plot the graph T
against d.
To is the value of the intercept on y axis
Substituting the value of To in
g=4Π2 L/To2
