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.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

2. OUTLINE
• INTRODUCTION
• BIOMETRIC TECHNOLOGIES
• BIOMETRIC PROCESS
• BIOMETRICS Vs TRADITIONAL TECH.
• CHARACTERISTICS OF GOOD BIOMETRIC
SYSTEM
• BENEFITS OF BIOMETRICS
3. INTRODUCTION
This is the ancient Greek word: Bio = “life”
and Metric = “measure.”
Biometrics are a range of technologies that
use specific physical and/or behavioral
characteristics unique to each individual to
either establish or confirm the identity of
that individual.
8. PALM PRINT
This technique include the estimation of
length, width, thickness and surface area of the
hand.
9. FACE RECOGNITION
• Face recognition uses the visible physical structure of
the face and analyses the spatial geometry of
distinguishing features in it to identify an individual.
13. RETINA GEOMETRY TECHNOLOGY
• A retinal scan involves the use of a low-
intensity coherent light source, which is
projected onto the retina to illuminate the
blood vessels which are then photographed
and analyzed.
• A retinal scan has an error rate of 1 in
10,000,000, compared to fingerprint
identification error being
sometimes as high as
1 in 500.
14. GAIT RECOGNITION
• Gait recognition is an emerging biometric
technology which involves people being
identified purely through the analysis of the
way they walk.
15. VOICE RECOGNITION
• Voice Recognition: is the Identification using the
acoustic features of speech that have been found to
differ between individuals.
• The vocal characteristics depend on the dimensions of
the vocal tract, mouth, nasal cavities and the other
speech processing mechanism of the human body.
16. •the angle at which the pen is held,
•the number of times the pen is lifted,
•the time it takes to write the entire signature,
the pressure exerted by the person while signing,
the variations in the speed with which different
parts of the signature are written.

17. KEYSTROKE DYNAMICS
Keystroke dynamics are the patterns of rhythm
and timing created when a person types.
Keystroke dynamics include:
• Overall speed
• Variations of speed moving between specific keys.
• Common errors.
• The length of time that keys are depressed.
18. BIOMETRICS Vs TRADITIONAL TECH.
Which is better? Neither is adequate for strong, practical
security on its own. Each has strengths and weaknesses, and
real security requires some combination of these or other
technologies.
PASSWORD It is simple to use, easy to implement and can be
reasonably strong. The problem is one of scale.
BIOMETRICS The use of physical traits such as fingerprints, irises,
faces or voices to identify persons – is more complex, but is
becoming more practical.
All forms of biometrics operate on the “close enough”
principle.
Combining both is “practical as well as strong”.
19. CHARACTERISTICS OF GOOD BIOMETRIC
