1.The Resilience of Life to Astrophysical Events

Abstract: Much attention has been given in the literature to the effects of astrophysical events on human and land-based life. However, little has been discussed on the resilience of life itself. Here we instead explore the statistics of events that completely sterilise an Earth-like planet with planet radii in the range 0.5–1.5R and temperatures of 300 K, eradicating all forms of life.

2.Achievement of Sustained Net Plasma Heating in a Fusion Experiment with the Optometrist Algorithm

Abstract:Many fields of basic and applied science require efficiently exploring complex systems with high dimensionality. An example of such a challenge is optimising the performance of plasma fusion experiments. The highly-nonlinear and temporally-varying interaction between the plasma, its environment and external controls presents a considerable complexity in these experiments.

3.Coronal mass ejections are not coherent magnetohydrodynamic structures

Abstract:Coronal mass ejections (CMEs) are episodic eruptions of solar plasma and magnetic flux that travel out through the solar system, driving extreme space weather. Interpretation of CME observations and their interaction with the solar wind typically assumes CMEs are coherent, almost solid-like objects.

4.Magnetic field sensor based on a combination of a microfiber coupler covered with magnetic fluid and a Sagnac loop

Abstract:This paper proposes a novel magnetic field sensor based on a microfiber coupler (MFC) combined with a magnetic fluid (MF) in a Sagnac loop formed from a polarization maintaining fiber (PMF). Thanks to the small (~2.6 μm) waist diameter of the MFC, the resulting interference is strongly influenced by the presence of the MF and this leads to the desirable high sensitivity of the structure to the applied magnetic field.

5.Invisibility Cloaking Scheme by Evanescent Fields Distortion on Composite Plasmonic Waveguides with Si Nano-Spacer

Abstract:A new, composite plasmonic waveguide based electromagnetic cloaking scheme is proposed with Si nano-spacer. Here we show, that the scattering fields of an object located on the cloak do not interact with the evanescent field, resulting in object’s invisibility. Finite difference time domain (FDTD) numerical calculations were performed to extract the modal distributions and surface intensities on a composite plasmonic waveguide with a metasurface overlayer.

6.Global mapping of stratigraphy of an old-master painting using sparsity-based terahertz reflectometry

Abstract:The process by which art paintings are produced typically involves the successive applications of preparatory and paint layers to a canvas or other support; however, there is an absence of nondestructive modalities to provide a global mapping of the stratigraphy, information that is crucial for evaluation of its authenticity and attribution, for insights into historical or artist-specific techniques, as well as for conservation.

7.Superconductivity in Ti4O7 and γ-Ti3O5 films

Abstract:Titanium dioxide is one of the most popular compounds among simple oxides. Except for the fully oxidized titanate, titanium oxides have partially filled d states and their exotic properties have captured attention. Here, we report on the discovery of superconductivity in Ti4O7 and γ-Ti3O5 in a thin film form.

9.Characterization of an industry-grade CMOS camera well suited for single molecule localization microscopy – high performance super-resolution at low cost

Abstract:Many commercial as well as custom-built fluorescence microscopes use scientific-grade cameras that represent a substantial share of the instrument’s cost. This holds particularly true for super-resolution localization microscopy where high demands are placed especially on the detector with respect to sensitivity, noise, and also image acquisition speed.


10.Quantum detection of wormholes

Abstract:We show how to use quantum metrology to detect a wormhole. A coherent state of the electromagnetic field experiences a phase shift with a slight dependence on the throat radius of a possible distant wormhole. We show that this tiny correction is, in principle, detectable by homodyne measurements after long propagation lengths for a wide range of throat radii and distances to the wormhole, even if the detection takes place very far away from the throat, where the spacetime is very close to a flat geometry.

A New Perspective on Robots and How They Will Shape Humanity (390)

( Throughout the years, technology has improved drastically - creating machines and devices that were unimaginable 50 years ago. And perhaps the most advanced and interesting of society's technological advancements is robots - but it is also the most misunderstood.

In fact, according to recent Pew Research, more than 70 percent of Americans express concern about a world in which machines perform many of the tasks done by humans.

Fortunately, there are people who believe humans and robots can coexist and work together in harmony and are working to debunk many of the fears people have about them.

Mouser Electronics Inc., a leading semiconductor and electronics component distributor based in Fort Worth, TX, and celebrity engineer Grant Imahara, have teamed up again for the fourth consecutive year for their Empowering Innovation Together program.

This year's program is called Generation Robot, which features five videos filmed across the world, including in the U.S., Germany and Japan. Mouser's goal is to reach innovators around the globe by showing how robots have a positive impact on humanity and change how people see the possibility of interacting with them.

Throughout the Generation Robot series, the entire spectrum of robotics will be examined, as will the understanding of how robots not only have a technological impact on society, but also a social and moral one.

The video series begins with the Imahara visiting the Institute for Robotics and Intelligent Machines at Georgia Tech and speaking with the executive director, Dr. Magnus Egerstedt.

There, he explores several aspects of robots, such as the basics of the machines, myths and misconceptions, as well as the hopes for, and fears of, the advancement of robot technology.

In the video, Dr. Egerstedt mentions that robots used to be about mechanical engineering, but now modern robots involve psychology, because these machines will be working along with humans and thus they need to understand people.

The second video, which takes place in Augsburg, Germany, dives into the real meaning of robots and humans working together, as well as the way this interaction will benefit society.

The third video, which comes out in mid-July, will focus on the all-robot-staffed hotel in Nagasaki, Japan, where Imahara investigates the way robots behave utilizing only artificial intelligence.

Sharath akkineni – Hyderabad, India

My journey towards Himalayas started with a celebration, it was the time of Maha Sivaratri. Firstly went to Sivananda ashram for my course and that evening i took a sacred bath in ganges at Sivanand ghat.Then the journey continued for 70 days where I learnt through the philosophy of yoga and followed by practice taught over there. Along Side we went to few places like Ram jhula, laxman Jhula, Triveni ghat and a trek towards Neelkant where our eyes went to a toss looking at the beauty of Himalayas.

Philosophy of life

What is the biggest achievement in your life?

Hello friends, Life is a complex journey, isn't it ?  But ease of handling life and quality of life is measured by the actions we take for every reaction with the surrounding people.

We have everything to live a happy life, more or less.

Don't we ? Probably the most crucial things Like a roof over head, food to survive this was sufficient for a man we thought. People to live with? No, we lack in that last fact, We have less connected with people than actually we bond with the gadgets.

Our procrastination is mostly controlled by “The devices”, those which we started use for making ease of life, but now gadgets started betraying us, or we started using more? Does these devices ranging from a palm phone to computer laptops, they help us to connect with the world, but will they help us in Connecting directly to people’s heart?, will they enhance your bonding.. ?

I would say spend time in carving the life, rather than picturing the life in the virtual world, spend lots of time with people. I’m not denying we should not use these , but everything falls to fit, but to its limit. So, the biggest achievement in life is handling the consistency of happiness, we often ask people How are you?, why would we ask that question, will our life cannot be happy all time.. I agree, the Joy And grief is part of life..

But merely they stay as one, where happiness might be today’s breakfast, surely we would end up a bad supper tonight. So how consistent you are in handing happy life. Actually, you don’t need to be aware of the things outside, you Will do it fine.. But do look into the inner thoughts, Will Reena love me? Will she hate me? Will my child pass exams, should I quit my job to find better. But in spite of these thoughts we will show a happy status in the WhatsApp and Facebook, who Knows the inside.

So Please know more the fresh and clear minded inside you, you end up in happy life outside, without actually aware you will choose best options in life, people will start noticing you, even you don’t tell them actually what you feel about them, problems get solved without greater efforts.  

We don’t need a happy status to spread across people… If your mind is clear with what you want, all will say, “ I feel you are happy this morning,” Cause life reflects that happiness and that joy, you don't need extra effort of saying, I’m happy.

So be noted, How consist you are in the handing happiness is the biggest achievement of your life. So did you achieve that consistency? at least 50% in your life, I will try my best to achieve at least 99.99%, cause at max i need 100% consistency.  That’s my achievement.
