The feeling is all-too familiar: Sitting in a stuffy lecture hall, audience members feel like time stretches beyond infinity. They daydream. Giant waves collapse. Turbulences swirl. Singularity takes over. But what if one could experience – and comprehend – all that by paying attention to the lecturer? Here’s an opportunity to do just that.
Come fathom the rogue waves and strong collapse turbulences at the Skoltech Colloquium.
Speaker: Professor Pavel M. Lushnikov, University of New Mexico (USA)
What: Finite time singularities, rogue waves and strong collapse turbulence.
When: May 22, 16:00pm
Where: Institute of Gene Biology RAS, Vavilova street 34/5, Conference room, 1st floor.
Abstract:
Many nonlinear systems of partial differential equations have a striking phenomenon of spontaneous formation of singularities in a finite time (blow up). Blow up is often accompanied by a dramatic contraction of the spatial extent of solution, which is called by collapse. Near singularity point there is a qualitative change in underlying nonlinear phenomena, reduced models lose their applicability and other mechanisms become important such as inelastic collisions in the Bose-Einstein condensate, optical breakdown and dissipation in nonlinear optical media and plasma, wave breaking in hydrodynamics. Collapses occur in numerous reduced physical and biological systems including a nonlinear Schrodinger equation (NLSE) and a Keller-Segel equation (KSE). We will focus on the collapse in the critical spatial dimension two (2D) which has numerous applications. For instance, 2D NLSE describes the propagation of the intense laser beam in nonlinear Kerr media (like usual glass) which results in the catastrophic self-focusing (collapse) eventually causing optical damage as was routinely observe in experiment since 1960-es. Recently such events have been also often referred as optical rogue waves.

Another dramatic NLSE application is the formation of rogue waves in ocean. 2D KSE collapse describes the bacterial aggregation in Petri dish as well as the gravitational collapse of Brownian particles. We study the universal self-similar scaling near collapse, i.e. the spatial and temporal structures near blow up point. In the critical 2D case all these collapses share a strikingly common feature that the collapsing solutions have a form of either rescaled soliton (for NLSE) or rescaled stationary solution (for KSE). The time dependence of that scale determines the time-dependent collapse width L(t) and amplitude ~1/L(t). At leading order L(t)~ (t_c-t)^{1/2} for all mentioned equations, where t_c is the collapse time.
Collapse however requires the modification of that scaling which in NLSE has the well-known loglog type ~ (\ln|\ln(t_c-t)|)^{-1/2} as well as KSE has another well-known type of logarithmic scaling modification. Loglog scaling for NLSE was first obtained asymptotically in 1980-es and later proven in 2006. However, it remained a puzzle that this scaling was never clearly observed in simulations or experiment. Similar situation existed for KSE. Here solved that puzzle by developing a perturbation theory beyond the leading order logarithmic corrections for both NLSE and KSE. We found that the classical loglog modification NLSE requires double-exponentially large amplitudes of the solution ~10^10^100, which is unrealistic to achieve in either physical experiments or numerical simulations. In contrast, we found that our new theory is valid starting from quite moderate (about 3 fold) increase of the solution amplitude compare with the initial conditions. We obtained similar results for KSE. In both cases new scalings are in excellent agreement with simulations.
This efficiency of analytical results also allowed to study 2D NLSE-type dissipative system in the conditions of multiple random spontaneous formation of collapses in space and time.
Dissipation ensures collapse regularization while collapses are responsible for non-Gaussian tails in the probability density function of amplitude fluctuations which makes turbulence strong. Power law of non-Gaussian tails is obtained for strong NLSE turbulence which is a characteristic feature of rogue waves. We suggest the spontaneous formation optical rogue from turbulent as a perspective route to the combing of multiple laser beams, generated by a number of fiber lasers, into a single coherent powerful laser beam.

* Wearing a robot that makes you feel as happy – or sad – as your friend while you’re instant messaging.
* Nurses train in life saving techniques by carrying external skeletons that weigh exactly like a real patient.
* Putting on a technology that makes your body sensitive to faraway objects.
It all does sound a bit like sci-fi. But wearable haptic technology, or haptics, is very real.
Originally it meant ‘to touch’ in Greek. Nowadays it is described as “doing for the sense of touch what computer graphics did for vision”. And what’s revolutionary about this hot research topic is that is has serious real world applications.
In this week’s Skoltech Seminar, Dr. Dzmitry Tsetserukou explores, explains and demonstrates some of the most amazing – and very real – applications of wearable tech.

Title: «Nanoscale simulations for clean renewable wearable haptic technologies for telexistence, telecommunication, and medical applications»
SEMINAR ABSTRACT:
Wearable haptic technology is a category of devices incorporating electronic technology and haptic actuators for presentation of tactile stimuli (force, vibration, pressure, temperature) to the wearer. The talk will focus on four mainstream projects employing wearable interfaces with haptic feedback: NAVIgoid, NurseSim, LinkTouch, and iFeel_IM!.
NAVIgoid consists of a master wearable robot and intelligent mobile robot. The developed interface allows the operator to use their body posture and gestures for controlling the mobile robot and at the same time to feel remote objects through sense of touch.
NurseSim is a novel VR simulator for nurses who become better at carrying an unconscious persons and maintain their posture correctly by wearing a haptic exoskeleton. Nurses lift the ‘body’ of care-receiver in simulated 3D environment. The haptic display generates a sensation of the patient’s weight.
LinkTouch is an innovative wearable haptic device with a five-bar linkage mechanism for presentation of 2-DoF force feedback at the finger pad. The application of Link-Touch for a wrist-worn device capable of online blood pressure measurement will be demonstrated.
iFeel_IM! is an intelligent system for feeling enhancement. It is powered by affect sensitive Instant Messenger which intensifies feelings and reproduces the emotions felt by a partner during online communication. The system elicits emotions by rich haptic and visual stimuli.

When Sidney Altman walks into the gilded lobby of Hotel Ukraine in central Moscow, the question seems inevitable: Could current political tensions destroy scientific relations that took years to build? The American scientist visiting the Russian capital for the first time does not take long to answer.
“They might, but they should not. Politics cannot be allowed to intrude on science and research. We must not let that happen”, says the Yale professor when we meet for a short chat ahead of his seminar at Skoltech. “I see myself part of this project and my commitment has not changed because of international tensions.” In fact, he adds, he currently contemplates deepening his relationships with Russian researchers working an institute in Novosibirsk.
Perhaps at the age of 75 Altman, one of America’s most eminent molecular biologists, can pursue unorthodox ideas without worrying too much about repercussions. Perhaps that is exactly the attitude which won him a Nobel Prize in chemistry for the discovery of catalytic properties of RNA. And perhaps that is what happens when a veteran researcher who won the Nobel prize decides to give humanity a gift of unmeasured value: eradicating malaria.
To make good on a vision of saving millions of lives he needs to convince the world that the blockbuster drugs currently marketed by pharmaceutical companies will pale in comparison to his unique solution. Altman and his team suggest that large nucleic acid molecules can easily bind to the RNA of the parasite that causes malaria and debilitate it. “It might be quite easy, easier than what most people think”, the science man coolly describes his quest to destroy a disease that claims the lives of more than half a million people a year.
The prestige he enjoys as a Nobel laureate buys him respect worldwide. People listen. Researchers, students, journalists, even the representatives of drug companies, are attentive when he speaks. And he does, whenever and wherever he can.
“It is working in the lab. We can stop the growth and development of various strains of malaria that are resistant to all the drugs we have today.” He enthuses when he speaks of a new age of antibiotics.
So what stands between him and becoming a 21st century Louis Pasteur? Funding, or rather, lack thereof. Funding is the other crucial part of the equation.
“The problem is the big pharmaceutical companies, relying on small molecules and their derivatives for treatment. They were not very successful so far. But they would not develop a new big-molecule solution, because it costs them too much money to try out. It is inexcusable. But perhaps if I could find a million dollars to repeat the initial results my team found with mice, then we would stand a chance of persuading pharmaceutical companies to invest.”
Enter the Russian government. It granted an estimated 90 million rubles (2.5 million dollars) to the researchers Altman is associated with at the Institute of Chemical Biology and Fundamental Medicine in Novosibirsk.
“I think it’d be ideal to start my effort in Russia. Russian pharmaceutical companies have never been on par with Europe and America in terms of developing drugs. But because of that, there is a potential and an opportunity here. New antibiotics can be tested and developed in Russia and the process would even be less expensive. I am sure it can be done here. And that is what matters: find a solution.”

3 things you want to know about Sidney Altman
Growing up in Montreal, Canada, he used to be a hockey player and a fan of the game. Not anymore. “Professional hockey now is a much rougher game. The finesse and beauty have disappeared from the upper levels. It’s not the same game as it was in the 1960’s and 1970’s when big Russian players like Vladislav Tretiak and Valeri Kharlamov ruled the rinks”.
He studied Russian for two years so he could read the great masters of prose and poetry: “Pushkin, Turgenev, Tolstoy, Dostoyevsky. I read them all, in Russian.”
His only word of advice to students boils down to two words: “Hard work. You cannot work with any concept of public recognition, fame, money and all that. That’s a terrible curse. You have to focus on the science and the problems you’re trying to solve.”

More detailed information about the projects:
1. A platform approach to the development of new antibiotic leads based on microcins
Research Area: Gene- and nano-medicine, Translational medicine
Project Summary:The rapid global spread of bacterial resistance to existing antibiotics and the dearth of development of new antibiotics leads to a significant societal problem that will become even more serious if no action is taken in the near future (it also happens to be the subject of our May 12 seminar with Nobel laureate professor Sidney Altman). This proposal aims to try to help solve this problem by developing and evaluating antibacterial agents based on microcins – ribosomally-encoded antibacterial peptides. Unlike most antibiotics, which are synthesized by complex enzymes, microcin peptide precursors are encoded by genes. Therefore, the power of molecular genetics can be brought to create large libraries of microcin derivatives among which molecules with desired properties can be sought for further development.
Nanopipette electrochemical biosensors
Research Area:Gene- and nano-medicine
Project Summary:Project is focused on development of modification methods for electrodes integrated in nanopipette. The research team has already obtained preliminary results on application of modified nanopipette for intracellular biosensing. Tools based on double barrel nanopipettes with integrated sensitive electrodes have a great potential to be implemented in pharmaceutical companies for drug discovering. Equipment based on “Smart” nanopipette technology will enable 35000 times faster screening and a 5000 times reduction in the number of cells required.
3. Superhydrophobisation of synthetic fabrics by deposition of ultrathin fluoropolymer films from solutions in supercritical carbon dioxide
Research Area: Advanced materials
Project Summary:We propose a new promising technique of imparting superhydrophobic properties to synthetic fabrics by depositing ultrathin fluoropolymer films from the solutions in supercritical carbon dioxide (SC CO2). This technology has a wide range of applications. It will allow to create self-cleaning breathable waterproof fabrics for production of clothes and outdoor equipment. While participating in the Program the team plans to develop prototypes of fabrics with stable superhydrophobic properties.
4. Perspective graphene-based materials with high absorption index in visible and near IR range
Research Area: Quantum physics/technology; Advanced materials
Project Summary:The project implies the development of the fabrication technology and studies of optical characteristics of Carbon Nanowalls (CNWs) in a wide wavelength range from 300 nm up to 200 μm. The main idea is to optimize the CNWs fabrication technology in order to compose highly absorptive and nonreflective nanocoatings.
5. Multisensor Device for Instrumental Toxicity Assessment
Research Area: Machine learning and artificial intelligence; Advanced materials
Project Summary:This project aims to develop and advance the multisensor device and software for instrumental toxicity assessment in environmental monitoring. Recently we accomplished the proof of concept for a new approach to toxicity evaluation. This new concept is based on instrumental measurements in samples with a specially developed electrochemical multisensor system and multivariate processing of the obtained data. This combination of sensor array and chemometric techniques allows for toxicity determination in terms of bioassay without immediate involvement of living creatures (besides on a calibration stage); measurements are fast and simple; the results are in toxicity units of corresponding biotest method. Such kinds of experiments are unique and were never reported in scientific periodicals before and we see a very attractive business opportunity in their advancement towards the environmental monitoring market.
6. Superplastic aluminum sheets
Research Area: Advanced materials; Composite materials, structure, and construction
Project Summary:Superplasticity is the specific state in which solid crystalline material can be deformed well beyond its usual breaking point: usually more than 200 % during tensile deformation. This project is direct to the optimization of the alloys composition and laboratory technology of superplastic aluminum sheets producing. The main purposes of the project include developing of the new materials, and producing the thickened sheets for commercial introduction. The new materials offers opportunities to reduce part count by forming components in a single piece, increase structural integrity of the part and assembly, reduce part weight, and speed up final assembly.

Title: «COMPUTATIONAL METHODS FOR CRYSTALLINE DEFECTS: CONSTRUCTION, ANALYSIS, AND BENCHMARKING»
SEMINAR ABSTRACT: Defects, defined as irregularities in the periodic arrangement of atoms, determine various important properties of crystalline materials. Such crucial features are plasticity or failure.
Computing defects such as dislocations or cracks is often challenging, because the spatial and temporal scales accessible for direct molecular simulations are limited. Dr. Shapeev’s talk will be devoted to efficient methods for computing crystalline defects. He will focus on atomistic-to-continuum (AtC) coupling, a popular approach utilizing atomistic resolution near the defect core while using the continuum model to resolve the elastic far-field.
Nobody is perfect. Not even crystals
In his talk Dr. Alexander Shapeev will
Give a brief introduction to crystalline defects and AtC coupling.
Report one of the recent developments in construction of a consistent energy-based AtC coupling method.
Present a mathematical theory of how to optimize and compare the performance of existing methods.
The first part of the talk will be devoted to his past research on computing static properties of defects, such as atomistic configuration or formation energy. In the second part, Alexander will speak about the present research and future plans on dynamics of defects and finite temperature.
