موت ھے اور موت کے خدشات ہیں
سنسنی  ھے ان  دِکھے  خدشات  ہیں

خوف پھیلا ھے وبا کے روپ میں
قریہ قریہ پل رہے  خدشات  ہیں

گر کوئی  تریاق  ھے  وہ ھےیقیں
زہر کی صورت لیے خد شات ہیں

اس صدی کے آدمی , تو, ھے خدا؟
تو نے ہی پیدا کیے خد شات ہیں؟

دائرہ    در   دائرہ    تشکیک   ھے
بے طرح پھیلے ہوئے خدشات ہیں

تجھ میں ہمت ھے تو ان کو مات دے
اے  نئے   انساں   نئے   خدشات    ہیں         
           --            --

وہ  گلی  کے موڑ  پر  ھے  منتظر
ڈررہا ہوں میں مرے خدشات ہیں

جرا ثیموں بھری سوئی سے تن کو سی رہے ہیں
دوائی زہر سی ھے زہر بھی تو پی رہے ہیں

ہمارا سانس ہی سر طان بن جائے نہ دل کا
ہم ایسی حبس آمیزہ ہوا میں جی رہے ہیں

قرنطینہ میں رکھے ہوں یا اہراموں کے اندر
بدن عبرت  سرا ماحول  پرطاری  رہے  ہیں

تگ و تازِ نفس  ھے موت  کے مدِمقابل
لہو انسان کا نادیدہ کیڑے پی رہے ہیں

سرشتِ  آدمی  میں  ہارنا شامل  نہیں  ھے
مسائل جوبھی ہیں حالات جیسے بھی رہے ہیں

تو کیا ھے گر ملا لیں جھوٹ اور سچائی کے جِین
وہ ایسے تجربے ویسے بھی تو کر ہی رہے ہیں

نئی دنیاؤں کے جو پاسورڈ سوچے ہیں ہم نے
وہ عاصم زندگی کی ابتدائی,, کی,, رہے ہیں

Professor Andrew Nix, Wireless Communication Systems, University of Bristol and Roger Nichols, Keysight’s 5G Program Manager. 5G research in the UK is kicking into gear, as the University of Bristol has announced a new collaboration with Keysight Technologies. The two companies are already focused on developing and testing 5G technologies, but by collaborating they’ll be able to combine Keysight’s experience with millimetre-wave and ultra-broadband design and testing with the University of Bristol’s wireless research. This combining of skillsets will help speed the development of the new capabilities needed for 5G. The two organisations will be particularly focused on trying to understand the nuances of millimetre-wave frequencies, using Keysight’s millimetre-wave channel sounding hardware and software and the University of Bristol’s advanced antenna and ray-tracing technologies to explore these frequencies in a test environment. Millimetre-wave frequencies are much higher than those currently used by mobile networks, but they may be required to provide the amount of bandwidth needed for 5G. “I am delighted to formalize our collaboration with Keysight. Their world-leading millimetre-wave design, test and measurement facilities radically enhance our ability to contribute to global 5G developments,” said, Professor Andrew Nix, Wireless Communication Systems, Dean of the Engineering Faculty and Head of the Communication Systems and Networks research group, University of Bristol. “Through our Centre for Doctoral Training in Communications we will use the Keysight tools to equip a new generation of engineers with the skills needed to develop and roll-out 5G networks.” “The multi-gigahertz bandwidth capability of the Keysight platform will give us greater insight into the propagation mechanisms at millimetre-wave frequencies and facilitate our research in projects such as mmMagic” said Professor Mark Beach, Communication Systems and Network Research Group, manager CDT in Communications, University of Bristol. “This equipment will work hand-in-hand with the stacked-bandwidth capability of our Anite Propsim F8 channel emulators recently procured through an U.K. EPSRC equipment award.” This follows the recent announcement that the University of Bristol had set up its own closed 5G network. Along with the 5G Innovation Centre at the University of Surrey the University of Bristol looks set to be at the forefront of 5G research in the UK.

The arrival of 5Gwill bring about higher mobile network connection speeds and greater data capacity. In order to power this boosted performance, however, new base station technology is required. Base stations are a key bottleneck through which all mobile network traffic must pass. It’s this bottleneck that currently restricts 4G to an average peak data rate of 50 megabits per second, and prevents it from being able to handle true real time transmissions. Conversely, 5G could well enable real-time radio communication and maximum data rates of 10 gigabits per second. The Fraunhofer Institute for Applied Solid State Physics IAF in Freiburg, Germany, claims to have “special knowledge on how to widen this bottleneck”. Its researchers are developing new types of power amplifiers that can send higher quantities of data more quickly than current 4G technology. These new power amplifiers utilise additional radio frequencies of up to 6 gigahertz - LTE, by comparison, is limited to 2.7 gigahertz. However, while these higher frequencies lead to faster data transmission, they are also much harder to power efficiently. As such, Fraunhofer IAF’s scientists are using gallium nitride (GaN) to create power transmitters that are better suited to higher 5G frequencies. Dr. Rüdiger Quay of Fraunhofer IAF explains, “Due to its special crystal structure, the same voltages can be applied at even higher frequencies, leading to a better power and efficiency performance”. Combined with new electronically steerable antennas that will deliver data to customers with pinpoint accuracy, 5G networks will be able to handle an expected 200-fold increase in data transmission without a massive increase in power expenditure.

State is the place where the data comes from. You should always try to make your state as simple as possible and minimize number of stateful components. If you have, for example, ten components that need data from the state, you should create one container component that will keep the state for all of them. Using Props Code sample below shows how to create stateful component using EcmaScript2016 syntax. App.jsx importReactfrom'react';classAppextendsReact.Component{ constructor(props){super(props);this.state ={ header:"Header from state...","content":"Content from state..."}} render(){return({this.state.header}{this.state.content});}}exportdefaultApp; main.js importReactfrom'react';importReactDOMfrom'react-dom';importAppfrom'./App.jsx';ReactDOM.render(, document.getElementById('app'))

In this tutorial we will show you how to combine components to make the app easier to maintain. This approach will allow you to update and change your components without affecting the rest of the page. Stateless Example Our first component in example below isApp. This component is owner ofHeaderandContent. We are creatingHeaderandContentseparately and just adding it inside JSX tree in ourAppcomponent. OnlyAppcomponent needs to be exported. App.jsx importReactfrom'react';classAppextendsReact.Component{ render(){return();}}classHeaderextendsReact.Component{ render(){return(Header);}}classContentextendsReact.Component{ render(){return(ContentThe content text!!!);}}exportdefaultApp; To be able to render this on page, we need to import it inmain.jsfile and callreactDOM.render(). We already did it when we were setting environment. main.js importReactfrom'react';importReactDOMfrom'react-dom';importAppfrom'./App.jsx';ReactDOM.render(, document.getElementById('app')); Above code will generate following result: Stateful Example In this example we will set the state for owner component (App). TheHeadercomponent is just added like in the last example since it doesn't need any state. Instead of content tag, we are creatingtableandtbodyelements where we will dynamically insertTableRowfor every object from thedataarray. You can see that we are using EcmaScript 2015 arrow syntax (⇒) which looks much cleaner then the old JavaScript syntax. This will help us create our elements with fewer lines of code. It is especially useful when you need to create list with a lot of items. App.jsx importReactfrom'react';classAppextendsReact.Component{ constructor(){super();this.state ={ data:[{"id":1,"name":"Foo","age":"20"},{"id":2,"name":"Bar","age":"30"},{"id":3,"name":"Baz","age":"40"}]}} render(){return({this.state.data.map((person, i)⇒)});}}classHeaderextendsReact.Component{ render(){return(Header);}}classTableRowextendsReact.Component{ render(){return({this.props.data.id}{this.props.data.name}{this.props.data.age});}}exportdefaultApp; main.js importReactfrom'react';importReactDOMfrom'react-dom';importAppfrom'./App.jsx';ReactDOM.render(, document.getElementById('app')); NOTE Notice that we are usingkey = {i}insidemap()function. This will help React to update only necessary elements instead of re-rendering entire list when something change. It is huge performance boost for larger number of dynamically created

React uses JSX for templating instead of regular JavaScript. It is not necessary to use it, but there are some pros that comes with it. JSX is faster because it performs optimization while compiling code to JavaScript. It is also type-safe and most of the errors can be caught during compilation. JSX makes it easier and faster to write templates if you are familiar with HTML. Using JSX JSX looks like regular HTML in most cases. We already used it in environment setup tutorial. Look at the code fromApp.jsxwhere we are returningdiv. App.jsx importReactfrom'react';classAppextendsReact.Component{ render(){return(HelloWorld!!!);}}exportdefaultApp; Even though it's similar to HTML, there are a couple of things you need to keep in mind when working with JSX. Nested Elements If you want to return more elements, you need to wrap it with one container element. Notice how we are usingdivas a wrapper forh1,h2andpelements. App.jsx importReactfrom'react';classAppextendsReact.Component{ render(){return(HeaderContentThisis the content!!!);}}exportdefaultApp; Attributes You can use your own custom attributes in addition to regular HTML properties and attributes. When you want to add custom attribute, you need to usedata-prefix. In example below we addeddata-myattributeas an attribute ofpelement. importReactfrom'react';classAppextendsReact.Component{ render(){return(HeaderContentThisis the content!!!);}}exportdefaultApp; JavaScript Expressions JavaScript expressions can be used inside of JSX. You just need to wrap it with curly brackets{}. Example below will render2. importReactfrom'react';classAppextendsReact.Component{ render(){return({1+1});}}exportdefaultApp; You can not useif elsestatements inside JSX but you can useconditional (ternary)expressions instead. In example below variableiequals to1so the browser will rendertrue, if we change it to some other value it will renderfalse. importReactfrom'react';classAppextendsReact.Component{ render(){var i =1;return({i ==1?'True!':'False'});}}exportdefaultApp; Styling React recommends using inline styles. When you want to set inline styles, you need to usecamelCasesyntax. React will also automatically appendpxafter the number value on specific elements. You can see below how to addmyStyleinline toh1element. importReactfrom'react';classAppextendsReact.Component{ render(){var myStyle ={ fontSize:100, color:'#FF0000'}return(Header);}}exportdefaultApp; Comments When writing comments you need to put curly brackets{}when you want to write comment within children section of a tag. It is good practice to always use{}when writing comments since you want to be consistent when writing the app. importReactfrom'react';classAppextendsReact.Component{ render(){return(Header{//End of the line Comment...}{/*Multi line comment...*/});}}exportdefaultApp
