Shri. Parkala Prabhakar has shared the video of his interaction with Sardar Montek Singh Ji. Kindly share your intellectual and economic insight on this interaction. 

 It will take sometime for me to analyze the interaction and share my views on various social media platforms. 

 In an era, where economic views are driven by one's political thought processes, an apolitical conversation on the economic aspects was almost like "gush of fresh". Please excuse me for my literary misadventure, but, I insist on sharing this quote to express my feelings, and that of the audience, when they view this video. 

 "A gush of fresh AIR is what i get when i exit this glutton world through some beautifully carved stories with words placed rhythmically" Roshni. 

 I think, we should thank the organizers for giving freedom to Dr. Parakala to transform the conversion into a meaningful dialogue.

 I suspect, the conversation is not impromptu. There is a faint smell of the content being discussed beforehand back stage. It does look like a backstage planned conversation, or possibly, I am getting a bit nosey. even if it is true, it does contribute positively to the quality of the conversation. 

Hope, I have done my job as an "Usher"

Wielding a laser beam deep inside the body 19-01

 

Responding to an unmet need for a robotic surgical device that is flexible enough to access hard to reach areas of the G.I. tract while causing minimal peripheral tissue damage,

Robotic engineers from Harvard’s Wyss Institute and John A. Paulson School for Engineering and Applied Science (SEAS) have developed a laser-steering microrobot that can be integrated with existing endoscopic tools, which are used in minimally invasive surgeries. Their approach was reported in Science Robotics.

The ends of endoscopic tools must be highly flexible to enable visualization and manipulation of the surgical site in the target tissue. In the case of energy-delivering endoscopic tools, which allow surgeons to cut or dry tissues and stop internal bleeds, a heat-generating energy source is added to the end of the device.

Currently available energy sources, delivered via a fiber or electrode, limit surgical precision and can cause unwanted burns in adjacent tissue sections and smoke development. While laser technology would be an attractive solution, the laser beam needs to be precisely steered, positioned and quickly repositioned at the distal end of an endoscope, which cannot be accomplished with the currently available relatively bulky technology.

Led by Wyss Associate Faculty Member Robert Wood, the Charles River Professor of Engineering and Applied Sciences, and postdoctoral fellow Peter York at Wyss Institute for Biologically Inspired Engineering and SEAS, the laser-steering microrobot, in its miniaturized 6 by 16 millimeter package, can operate with the necessary high speed and precision required for minimally invasive surgeries.

“To enable minimally invasive laser surgery inside the body, we devised a microrobotic approach that allows us to precisely direct a laser beam at small target sites in complex patterns within an anatomical area of interest,” said York, the first and corresponding author on the study and a postdoctoral fellow on Wood’s microrobotics team. “With its large range of articulation, minimal footprint, and fast and precise action, this laser-steering end-effector has great potential to enhance surgical capabilities simply by being added to existing endoscopic devices in a plug-and-play fashion.”

The team needed to overcome the basic challenges in design, actuation, and microfabrication of the optical steering mechanism that enables tight control over the laser beam after it has exited from an optical fiber. These challenges, along with the need for speed and precision, were exacerbated by the size constraints — the entire mechanism had to be housed in a cylindrical structure with roughly the diameter of a drinking straw to be useful for endoscopic procedures.

“We found that for steering and re-directing the laser beam, a configuration of three small mirrors that can rapidly rotate with respect to one another in a small ‘galvanometer’ design provided a sweet spot for our miniaturization effort,” said second author Rut Peña, a mechanical engineer with micro-manufacturing expertise in Wood’s group. “To get there, we leveraged methods from our microfabrication arsenal in which modular components are laminated step-wise onto a superstructure on the millimeter scale — a highly effective fabrication process when it comes to iterating on designs quickly in search of an optimum, and delivering a robust strategy for mass-manufacturing a successful product.”

The team demonstrated that their laser-steering end-effector, miniaturized to a cylinder measuring merely 6 mm in diameter and 16 mm in length, was able to map out and follow complex trajectories in which multiple laser ablations could be performed with high speed, over a large range, and be repeated with high accuracy.

To further show that the device, when attached to the end of a common colonoscope, could be applied to a life-like endoscopic task, York and Peña, advised by Wyss Clinical Fellow Daniel Kent successfully simulated the resection of polyps by navigating their device via tele-operation in a benchtop phantom tissue made of rubber. Kent also is a resident physician in general surgery at the Beth Israel Deaconess Medical Center.

“In this multi-disciplinary approach, we managed to harness our ability to rapidly prototype complex microrobotic mechanisms that we have developed over the past decade to provide clinicians with a non-disruptive solution that could allow them to advance the possibilities of minimally invasive surgeries in the human body with life-altering or potentially life-saving impact,” said senior author Wood, who also is the Charles River Professor of Engineering and Applied Sciences at SEAS.

Wood’s microrobotics team together with technology translation experts at the Wyss Institute have patented their approach and are now further de-risking their medical technology (MedTech) as an add-on for surgical endoscopes.

The study was funded by the National Science Foundation under award #CMMI-1830291, and the Wyss Institute for Biologically Inspired Engineering.

hyderabadi Urdu interview of Moh. Siraj with Sridhar enjoy Hydrabadi Lingo

 Hyderabad: For all pucca Hyderabadis, watching apna Team India fielding coach R Sridhar in conversation with fellow Hyderabadi and Test debutant Mohammed Siraj must have been a zabardast delight. The typical Hyderabadi dialect commonly used in Irani hotels, play fields or among teammates brought smiles among the citizens from the land of the Musi.

The conversation went somewhere on these lines:

Sridhar: Aaj shaam mein mere saath hain Mohammed Siraj joh hamara Hyderabad ke ek dam ustad fast bowler pehle Test match MCG Boxing Day Test mei. VVS Laxman ke baad tum pehle Hyderbadi ho jo Hyderabad mein paida hua aur India ko debut kiya. Aap ka aaj kya maholl thaa aur kya lagrah thaa? (Today we have Hyderabad ustad and Hyderabad fast bowler. That too on Boxing Day at MCG. After Laxman you are the born and brought up in Hyderabad to make debut for India. How is the atmosphere and how are you feeling?)

Siraj replies: Mero Ko tho bahut hi acha lag rah thaa. Jaise ground mein utra aur jaise cap milee debut mein matlab sabse life mein bada achievement tha. Aur jaise mein ground mein utra, lunch tak ball nahi milee aur jaise drinks hua uske baad bowlers ne bahut acha kiye aur mere koh bhi Ajju bhai mujhse baat kar ke confident deh rahe the ke acha laaga aur mere baaju mein Jesse bhai the confident deh reh the. (I am feeling very happy. As soon as I entered the ground and when I made my debut it was my life’s biggest achievement. I entered the ground but I didn’t get bowling till lunch. The bowlers bowled beautifully. Ajju bhai (Ajinkya Rahane) gave me confident and so was Jesse)

Sridhar: Doosra sawal yeh pooch na tha, lunch tak ball nahi haath laga toh dimag mein kya chaal rah tha? Haatha khujara thaa kya?(Second question, till lunch you couldn’t get the ball. What was going through your mind and were your hands itching?)

Suraj: Haatha tho khujara rah thaa. Ajju bhai bolre the ki end mein aana. Uske ke baad bolthe toh aur warm up kiya. Mein bhi socha thaa theek hai wicket mein moisture hoga tho spinner ko helpful hain. Uske baad mein mai socha thaa run out mein kuch contribution karunga and confident bhi thaa. Uske lunch ke baad aya tho mera ek plan tha tho dot ball jaada dalun aur pressure build karoon kyun ki uske baad pressure mein wicket mileage (My hands were itching. Ajju bhai told me I would come from this end and I was warming up. I thought I would contribute by making a run out. After lunch, I had a plan to bowl dot balls and build pressure and then get wicket).

Sridhar: Aacha yeh pahle batao mujhe pehle cheh ball swing nahi hoh raha thaa uske baad doosra spell aap dono taraf idhar udhar swing kar reh the. Kya toh bhi woh kissa? (You didn’t swing the first six balls but in the second spell you could swing the ball both ways. What was this about?)

Siraj: Woh toh natural hai sir. Mein yeh try kar rah tha ki matlab thoda close stumps aah raa thaa and uske baad mein wide off stumps daal raa tha. Mera angle natural in swing tha and aur bhi swing hoh raha tha. (It is natural for me sir. I was bowling close to the stumps and then bowled outside the off stump. I have natural in swing)

Sridhar: Cameron Green ko zabardast set kiye aur uske baad zabardast catchaan pakde outfield mein? (You set up Green nicely and took fine catches in the outfield)

Siraj: Cameron ghiri tika tho jab mera bahar bhi acha aur andar bhi acha aah rah thaa. . Usko andhar andhar dala thaa uske baad do over usko bahar dala but eek dum eek ball andhar daala thaa. Bahut acha laga set kar ke. Jaisa fielding ki tension nahi thi woh yeh cheez ki. (I was bowling outswingers and I bowled with inswingers but I brought one in nicely. There was no tension while fielding).

The Hyderabadi lingo brought memories to many past cricketers. Former fast bowler Rajesh Yadav and former wicketkeeper Youraj Singh said it was always fun when we talk in Hyderabad dialect. Words like haule, chillar kahin, dimagh hi nah hai, bewakoof.

P Harimohan, echoed the same feeling. “The lingo is so unique that whoever hears it can’t help laughing. It’s so typical of our happy go lucky culture.’
