Unstable or injuries with deficits generally require surgical stabilization to restore alignment and prevent further injury, while stable injuries may be treated non-operatively with bracing or casting.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

9. Systemic Approach:
1.Coverage : All cervical vertebrae are visible
from the skull base until T1
2. Alignment: 4 longitudinallines
❖ Anterior Vertebral Line: line of theanterior
longitudinal ligament
❖ Posterior Vertebral Line: line ofthe
posterior longitudinal ligament
❖ Spinolaminal Line: line formed by the
anterior edge of the spinous processes
❖ Spinous Process Line
3. Bones: vertebral body height
4.Spacing: Discs and spinous process
(should be approximately equal in height)

normal lumbar lordosis
2. Bones: vertebral body height,
outline of the bone/fracture /
bony erosion (lytic or
sclerotic)
3. Spacing: Disc should be equal
in height
4. Pedicle:look for widening or
displacement of the pedicle
(which indicative of burst
fracture),

- Anterior part ofintervertebral
disk
- Anterior longitudinal ligament
Middle Column:
- Posterior half of vertebralbody
- Posterior part ofintervertebral
disk
- Posterior longitudinal ligament
Posterior Column:

🡪 Important to establish whetherthe
injury is stable or unstable
THREE COLUMN CONCEPT
14. 1. COMPRESSION FRACTURE
◼ Mechanism of injury: due to severe spinal flexion
◼ Traumatic /Non-traumatic
◼ Example: Fall from height on the heels or buttock
◼ Commonlyno neurological deficit
15. X-RAY FEATURES
✔ Reduce height of the
anterior vertebral body
✔ Anterior superior
endplate fracture of
vertebral body
✔ Wedge shape
appearance
✔ Posterior cortex intact
16. 2. BURST FRACTURE
❑ Mechanism due to severe axial compression may ‘explode’ the vertebral body,
❑ shattering the posterior part of vertebral body and extruding fragments of bone into the spinal
canal
❑ Example: fall from height in erect position, landing on the feet
❑ Usually unstable
❑ In cervical spine: this fracture commonly cause neurological deficit
❑ In thoracolumbar spine: this force rarely neurological deficit (due to wide canal at this level)
17. X-RAY FEATURES
- Both anterior and
middle column are
disrupted
- A large vertebral body
fragment is displaced
anteriorly
- Retropulsion of bone into
19. JEFFERSON FRACTURE
▪ burst fracture of the atlas C1
▪ described as a four-part fracture with
double fractures through the anterior
and posterior arches
▪ Mechanism injury : Axial loading along
the axis of the cervical spine (diving
headfirst into shallow water)
▪ Radiographs will show asymmetry in
the odontoid view
▪ treated conservatively (hard collar
immobilization)
20. HANGMAN FRACTURE
▪ known as a hyperextension injury causing bilateral
pedicular fracture of C2
▪ most common symptom : neck pain following a fall
or motor vehicle accident
▪ can be very unstable
▪ leading to increasing deformity that can result in
serious damage to the spinal cord or progressive
pain.
▪ Younger age group average
▪ Tx :immobilization and surgical intervention
21. CHANCE FRACTURE
❖ Also known as Flexion-Distraction
❖ Mechanism of injury: combined flexion and posterior distraction ( seen typically in severe
seat belt injuries)
❖ It is an unstable injury because posterior and middle columns fail under tension and
anterior column fails under compression
❖ Associated injury with GI injuries
❖ MRI to evaluate injury of posterior elements

24. HOWTO READASPINECT:
ABCS
- CT is often used to image fractures, ligament injuries
and dislocations
1. Adequacy of image and alignment
Assess spinal alignment on the scout and midsagittal
images. The normal lumbar spine has a smooth
lordosis. Relative lumbar kyphosis may be due to
degenerative disc disease or anterior vertebral collapse
27. 2. Bone
-Review each vertebral body in the bone window,
scrolling down the vertebral column
- Look for changes in bone density.
-midsagittal views, ensure the vertebral body is square
and of similar height to the adjacent vertebrae
3. Cartilage
-ensure that there is no loss of disc height, as
compared with adjacent levels, and look for endplate
fractures or abnormalities
-Further MRI can be requested if there is any clinical
suspicion.
28. 4. Soft tissue and spinal canal
- Look in the spinal canal, particularly in the axial and
sagittal views, to detect any abnormalities such as
retropulsed bone fragments from burst fractures
Burst fracture with
retropulsion into the
spinal canal. Spinal cord
injury should be
suspected and further
imaging such as magnetic
resonance imaging may
be required.
29. HOW TO READ MRI SPINE
There are two basic types of MRI images which differ by the timing of the
radiofrequency pulses, named T1-weighted images and T2-weighted images. T1
images highlight FATty tissue.T2 images highlight FAT ANDWATER within tissues.
41. •A0: no or clinically insignificant fractures of the
spinous or transverse processes
•A1: also known as wedge compression injuries;
they involve a single anterior or middle endplate
of the vertebral body without the involvement of
the posterior aspect
Type A Compression
Injury
42. •A2: also known as split or pincer type injuries;
they involve both endplates without the
involvement of the posterior wall
•A3: also known as incomplete burst injuries;
they involve a single end plate along with the
posterior vertebral wall; a vertical laminar
fracture is usually also present (insufficient to
qualify as a tension band failure)
•A4: also known as complete burst injuries; they
involve both end plates along with the posterior
vertebral wall and are also often associated with
a laminar fracture (insufficient to qualify as a
tension band failure)
43. B type : Distraction
Injuries
•B1: also known as Chance fractures or pure
transosseous tension band disruption; they
disrupt the pedicles and spinous process in a
single vertebral level; a distracted horizontal
fracture through the vertebral body is often but not
necessarily present
•B2: also known as osseoligamentous posterior
tension band disruption; they involve an
intervertebral body level with disruption to the
posterior tension band ligaments with or without
involving the posterior bones; a type A fracture is
often present and should be specified separately
44.
45. Type C injuries involve displacement in any
direction. No subtypes are present as there are
numerous possibilities of dislocating fractures.
