A MINIATURE ROBOTIC DEVICE APPLICABLE TO A FLEXIBLE ENDOSCOPE FOR THE SURGICA...Toscana Open Research
The invention is a tool installed as cap to the tip of an endoscope. The cap contains a teleoperation robot with 2 arms which the surgeon/endoscopist can control with an ergonomic console.Project report of ROBOTIC SURGERY
The document discusses the history and development of robotic surgery. It describes how the first robotic surgery device, the PUMA 560, was used in 1985 for brain biopsies. Later systems like PROBOT and ROBODOC were developed in the late 1980s and early 1990s. The da Vinci surgical system was approved by the FDA in 2000 and is now commonly used for procedures like prostatectomies and cardiac/gynecological surgeries. The da Vinci allows surgeons to operate remotely through small incisions while magnifying their hand movements. Robotic surgery provides benefits like shorter recovery times but drawbacks include the high costs of equipment and training. New innovations continue to advance the field.
Robotic Surgery: The New Age Orthopedic Solution
Over the years, technology has advanced itself, reshaping the landscape. Let’s understand the concept of the modern era of robotic surgery.
DEVELOPMENT of PROTOTYPE LAPAROSCOPIC GRASPER with HAPTIC FEEDBACK
The introduction of robot-assisted surgery into the operating room has revolutionized the medical field.
These systems not only have the advantages of traditional minimally invasive surgery (MIS), such as reduced patient
trauma and recovery time, lower morbidity, and lower health care costs, but they also eliminate surgeon tremor,
reduce the effects of surgeon fatigue, and incorporate the ability to perform remote surgical procedures. However,
current robotic surgical systems, such as the Da Vinci™ Surgical System, lack the capability of providing force
feedback to the surgeon that is present in conventional surgery. Therefore, this lack of force feedback presents
excellent developmental opportunities for surgeons and engineers to create novel surgical tools and methods to
incorporate force feedback capabilities into these robotic surgical systems. The goal of this research is to restore force
feedback capability to the surgeon in robot-assisted surgery through a haptic interaction experience involving force
feedback from the surgical site using our novel teleoperation platform. This project will summarize our research
including: 1)The Laparoscopic tool will be mounted over robotic arm.2)The Laparoscopic grasper can be integrated
with force feedback system and tactile system.3)Incorporation of master slave technique in prototype model.4)The
sensors will be used to transmit force data to slave controller and then transmitted wirelessly to master controller
which then controlled by servo motor(force feedback device.5)Opening and closing process of Laparoscopic grasper is controlled by servo motor.
An instrument comprising a contact force sensor device
The technology consists of a contact force sensor comprising an inflatable balloon, a processing unit receiving a signal of changes in pressure or deformation in the balloon and a device for notifying the operator of the contact force signal (compliance of fabrics) calculated by the processing unit.

Most surgeons and patients agree that minimally invasive surgery is preferable to open surgery, as it results in less post-operative pain, shorter hospital stays, and easier recovery. Both laparoscopic and robotic surgery are types of minimally invasive surgery. Laparoscopic surgery involves making several small incisions to insert small tools including a video camera, while robotic surgery uses a computer-controlled robot to manipulate instruments with greater precision via a 3D high-definition video feed. Robotic surgery allows for a greater range of motion than laparoscopic surgery and enables surgeons to access more difficult to reach areas. Both result in shorter recovery times compared to traditional open surgery.
Robotic Surgery
Robotic surgery uses robotic systems to assist surgeons with complex procedures. The da Vinci system is the most commonly used surgical robot. It has three components - a console where the surgeon sits, a patient-side cart with four robotic arms controlled by the surgeon, and a display for other medical staff. Robotic surgery provides benefits like improved 3D vision, more precise movements, and smaller incisions, leading to less invasive procedures and faster recovery times for patients. Robotic systems are used in various specialties like general surgery, urology, cardiothoracic surgery, and neurosurgery for procedures such as prostate removal and heart valve replacement.

The primary objective of medical tattooing is to restore part of a patient’s physical
integrity. Moreover, the procedure seeks to assist in psychological recovery from the
physical and/or psychological consequences of disease, surgery or trauma. The method
described in this brief note marks a step forward in the field of such tattooing. The
treatment simulates reconstruction of the nail bed, as the nails of the big toes had
previously been removed through a surgical avulsion procedure. This treatment, agreed
with the physician and performed by a tattooist with proven experience in medical tattooing,
also involved the use of specific colour nuances that resulted in an extremely
realistic outcome.

Robotic surgery
Robotic surgery involves a surgeon remotely controlling robotic surgical instruments to perform operations. The surgeon views the procedure using a control console while the robotic arms mimic the surgeon's hand movements. Some key advantages of robotic surgery include less pain and scarring for patients due to smaller incisions, faster recovery times, and improved dexterity over traditional laparoscopic techniques. However, higher costs remain a concern for widespread adoption of robotic surgery systems. Major systems include da Vinci and Zeus, which are used in various specialty areas like cardiac surgery and urology. Further research is still needed to fully evaluate robotic surgery's cost-effectiveness compared to conventional methods.
Sterilization in Orthodontics
This document summarizes a study that compared four methods for sterilizing orthodontic pliers: wrapped cassettes in an M11 ultraclave sterilizer, V-shaped pouches in an M11 ultraclave, wrapped cassettes in a Statim 5000 sterilizer, and V-shaped pouches in a Statim 5000. The study found that the most efficient method was using V-shaped pouches in the larger M11 ultraclave sterilizer, while the least efficient was using wrapped cassettes in the smaller Statim 5000 sterilizer. Following CDC guidelines and using pouches designed for hinged instruments like pliers allows for better sterilization than cassettes. While all methods
Robotic surgery

Minimal access surgery
This document provides an overview of minimal access surgery (MAS). It defines MAS as applying modern technology to minimize surgical trauma without compromising exposure or safety. The history of MAS is traced from early laparoscopic procedures in the 1900s to developments like natural orifice transluminal endoscopic surgery (NOTES) and single incision laparoscopic surgery (SILS) more recently. The advantages of MAS include reduced pain, wounds, and recovery time compared to open surgery. Potential complications include injuries and those related to pneumoperitoneum such as arrhythmias. A variety of endoscopic, laparoscopic, and catheter-based minimal access procedures across several specialties are described in the document.
general surgery
General surgery is the part of surgical science that studies patient care, principles of preventing and treating surgical infections through asepsis and antisepsis, anesthesia principles, trauma management, hemostasis, and purulent disease treatment. The key principles are anatomical access, technical possibility, and physiological permission. Asepsis aims to prevent wound contamination through sterilizing all objects touching the wound. Antisepsis eliminates microbes through mechanical, physical, chemical, and biological methods like wound debridement, light/heat, and antiseptic solutions.
Robotic surgery
Robotic surgery is a type of minimally invasive surgery. “Minimally invasive” means that instead of operating on patients through large incisions, we use miniaturized surgical instruments that fit through a series of quarter-inch incisions.
Presentation microsurgery
Microsurgery involves highly precise surgery performed under a microscope. It is used to reconnect small blood vessels and nerves after injuries and reconstructive procedures. Extensive training is required for surgeons to master the delicate techniques of microsurgery. Key aspects include reattaching amputated body parts, transplanting tissue flaps between areas, and repairing nerves and blood vessels down to a microscopic level. Microsurgery relies on specialized tools and sutures, as well as operating microscopes, to enable surgeons to visualize and manipulate tiny anatomical structures.

Sirit: the fascist internment system in Tuscany during World War II (1940-44)...Toscana Open Research
The research project focused on the Fascist internment system in Tuscany between 1940, when Italy joined the Second World War, and 1944, when the region was liberated by the Allied Army. During the war, the Fascist government and the Italian Social Republic adopted a series of measures restricting individual freedom. This led to the isolation, imprisonment, marginalization and control of anyone deemed dangerous for public security, even only on the basis of mere suspicion. These provisions resulted in a widespread and articulated network of internment devices that affected different categories of persons.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptx
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.

Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.
SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

- 2. Endoscopic surgical techniques, where possible, have significant advantages over standard surgery such as aesthetic micro-invasiveness, speed of recovery, shorter duration of operations with the relative benefits as regards the type of anesthesia. During endoscopic surgical operations, especially those for the regenerative treatment of worn cartilage, it is often necessary to deliver a drug and / or a regenerative substance to the restricted site of intervention. The prior art devices also allow to simultaneously extrude up to three different therapeutic substances at the same time, but do not give the surgeon the possibility of directing their application except by hand by moving the application nozzle with the arm. The object of the invention is a tool, new of its kind, to deliver therapeutic substances (e.g., biomaterials, stem cells, etc.) during arthroscopic micro-invasive surgery. This innovative device has the ability to direct the extruder in order to improve and maximize the efficiency of the application by the healthcare professional. Advantages of the proposed solution are: • Ability to direct the medical application on site thanks to the mobility of the extruder • Simplification of operations in arthroscopy • Ability to microstructure the material delivered in concentric layers that maximize its functionality Invention
