یہ امر ایک مسلم حقیقت ہے کہ ارتقائے زندگی کا اہم ترین جزو ہونے کے ساتھ ساتھ روشنی بقائے حیات کے لیے بھی لازم ہے۔ سائنس کی ترقی اور کائنات کے پوشیدہ رازوں کو جاننے میں روشنی کا کلیدی کردار رہا ہے۔ اربوں کہکشاؤں کی وسعتوں میں پھیلے کھربوں ستاروں کے احوال اور ان میں رونما ہوتی حشر سامانیوں کی داستانیں سناتی یہ روشنی اپنی ساخت میں ایک سحر انگیز کار گزار ہے۔ روشنی کی موج یا ذرّاتی ساخت سے متعلق تجربات و مشاہدات نے لگ بھگ تین سو برس وقت کے نامور سائنسدانوں کو انگشت بدنداں رکھا۔
بیسویں صدی میں کوانٹم میکانیات کی دریافت سے جہاں سائنس کی ترقی کے نئے دور کا آغاز ہوا وہیں روشنی اور اس سے جڑے نظریات بھی اس ارتقائی عمل سے محفوظ نہ رہے اور نتیجتاً کلاسیکی اور کوانٹم روشنی میں تفاوت کی صورت واضح ہوئی۔ یہ بات یہاں قابلِ ذکر ہے کہ روشنی کلاسیکی ہو یا کوانٹم، اس کے بنیادی ذرّے، یا توانائی کے پیکٹ، کو فوٹان ہی کہا جائے گا۔
کوانٹم میکانیات سے جُڑے انہی اسرار کی کھوج میں لمز یونیورسٹی کے سائنس اور انجینئرنگ سکول کے ڈین ڈاکٹر صبیح انور، ڈاکٹر علی اکبر اور طالبِ علم فیضان الہٰی نے کلاسیکی بصریات کے ایک مشہور رجحان کو کوانٹم روشنی سے جانچنے کا تجربہ کیا۔ کوانٹم روشنی کی افزائش ایک نان لینیئر کرسٹل سے کی گئی، جس میں قانون بقائے توانائی کو ملحوظ خاطر رکھتے ہوئے ایک خاص توانائی کا فوٹان دو کم توانائی والے فوٹانز میں تبدیل ہوتا ہے۔ ان میں سے ایک فوٹان کو مزید ایک ہمہ رخ کرسٹل مقناطیسی میدان کی موجودگی میں سے گزارا گیا اور روشنی کے تقطیبی خواص میں ہونے والی تبدیلی کا تجزیہ کیا گیا۔ اس تبدیلی کو گردشِ فاراڈے کہا جاتا ہے۔
یہ سائنسی کاوش اس لحاظ سے بھی منفرد ہے کہ اس تجربے سے حاصل ہونے والے نتائج کو خالصتًا کوانٹم میکانکی اصولوں )کوانٹم پراسیس ٹوموگرافی( سے پرکھا گیا اور ایک سنگل فوٹان کی گردشِ فاراڈے کی پیمائش کی گئی۔ کلاسیکی اور کوانٹم میکانیات کا حسین امتزاج ثابت ہونے والا یہ تجربہ طبیعات کی تین مختلف شاخوں یعنی کلاسیکی بصریات، کنڈینسڈ مادہ اور کوانٹم انفارمییشن کا خوبصورت ملاپ بھی ہے۔
اردو کے نامور شاعر، ن م راشد نے کہا تھا:
“تمنا کی وسعت کی کس کو خبر ہے جہاں زاد”
مگر یوں لگتا ہے جیسے تمنا کی بھی وہی وسعت ہے جو روشنی کو میسر ہے۔

Dr. Amna Ijaz cares deeply about taking the waste out of wastewater. Her work examines how tiny particles released after burning of biomass from one part of the planet, travel through international airspace landing conveniently on some bright white snowy peaks of another part of the planet, can have a sinister effect in aiding downstream water pollution. Dr. Amna’s search for answers has led herself to land in multiple continents in trying to understand how developments in technology can lend a helping hand to solve the aerosol problem.
Dr. Amna received her MPhil in Environmental Biotechnology from National Institute for Biotechnology and Genetic Engineering (NIBGE) in Faisalabad, Pakistan, where she participated in the development a sustainable and cost-effective wastewater treatment technology that has since been extensively installed in wastewater stabilisation ponds/canals in Pakistan by her mentor at NIBGE, Dr. Muhammad Afzal's research group, for water quality restoration. She then went on to the USA through the Fulbright Foreign Student Grant to pursue a PhD at Michigan Technological University (MTU, where her research shifted to Atmospheric Chemistry.
Using state-of-the-art ultrahigh-resolution mass spectrometric tools at MTU and Pacific Northwest National Laboratory, Washington, under the guidance of Dr Lynn Mazzoleni, Amna performed molecular-level characterisation of atmospheric aerosol collected downstream of wildfires, i.e., large-scale biomass burning events.
At SBASSE, Dr. Amna's teaching and research will primarily be focused on investigating chemical processes at the atmosphere (aerosol)-cryosphere (snow/ice) interface in high mountain areas of Pakistan and their impact on downstream water quality, along with an exploration of the current status of climate science and policy in Pakistan.
We congratulate and welcome Dr. Amna Ijaz to the Afiniti Fellowship program at SBASSE, LUMS, and wish her success in her academic and research endeavors.

Like a pencil balanced upside-down, the brain is a conglomerate of finely balanced neurological jugglery that is sophisticated enough to stir fascination yet delicate enough to respond boisterously to the otherwise imperceptible fraction of an electrical impulse. To untangle some of the most gripping mysteries of the brain requires an academic arsenal of astronomical proportions. This is where Dr. Farzada Farkhooi’s research interest comes in. Dr. Farkhooi’s research agenda as an Afiniti fellow will be devoted to developing the theoretical tools necessary to address important questions in the physics of brain dynamics and functions.
Understanding our brain is interdisciplinary research and spans across physics, mathematics, electrical engineering, computer science, and biology. Dr. Farkhooi envisions extending and catalyzing her scientific knowledge and links with the vibrant local communities at the SBASSE and forming a new solid research and teaching area here.
Dr. Farzada Farkhooi received a bachelor's from Allameh Tabataba'i University, Tehran, Iran, and her master's from the University of Nottingham, UK. She completed her Ph.D. at Freie Universität Berlin, Germany, in computational neuroscience in 2011. She was a postdoc fellow and visiting scholar at the National Institute of Health, Bethesda, USA, and CNRS, Paris, France. She established her independent line of research at the Institute for Mathematics at Technische Universität Berlin, Germany, in 2015. Afterward, she moved to the Institute for Theoretical Biology at Humboldt-Universität Berlin, Germany. Her work is pursued in close collaboration with outstanding experimental and theoretical research groups around the world. She is building a strong publication record with articles in journals such as Physical Review Letters, Physical Review E, PLoS Computational Biology, and Proceedings of the National Academy of Sciences.
Her life journey as a Muslim trans person, always moving, made her more resilient and resourceful in dismantling visible and invisible social barriers while doing cutting-edge research. “I quest to be on the path of conjoining myself with the active intellect, as al-Ghazālī phrases it in The Alchemy of Happiness (499 AH)— a process that, perhaps in our age, means creating a sacred space for liberating opportunities.”, says Dr. Farkhooi. Further expanding on her aspirations as an Afiniti fellow, Dr. Farkhooi said “I will contribute to the sensitization of the mentorship program to transform learning and research spaces for women and gender minorities so they can realize their full potential at SBASSE.”
We congratulate and welcome Dr. Farzada Farkhooi to the Afiniti Fellowship program at SBASSE, LUMS, and wish her success in her academic and research endeavors.

Communication has been at the heart of our survival. We itch to be heard, and to be understood. In modern times, the need to communicate has seen a reincarnation in that it is not only still part of our biological construct but also our civic and technological design altogether. Couple the fact that we can beam electronic signals through waves of energy and that the Earth is round, making it impossible for a beam of precious signals that inherently moves in a straight line, to follow the curves path of our world’s contours. We needed something better – we needed satellites!
In this work, Dr. Naveed ul Hassan and his co-authors worked out the energy efficiency of a satellite network coupled with ground infrastructure and compared it with the energy efficiencies of Traditional Terrestrial Heterogeneous (TTH) and Long-Term Evolution (LTE) networks (in other words – older technology). For an increasing cell density, it was shown that the satellite-terrestrial network performs better in terms of energy efficiency as compared to the TTH and LTE networks. These results are promising and show that satellite networks can complement terrestrial networks for providing communication resources to the users.
Communication satellites have been in service for a long time. They are used to provide communication services to far off and difficult to reach places. Conventional satellites have been large-sized, expensive, and very difficult to deploy. They are also very far away, which introduces significant lag. With the recent uprise of the Internet of Things (IoT) and wireless networks, the service requirements have changed. High data rates with low latency are required, and the current ground-based infrastructure is already overloaded. Due to these circumstances, a rise to the development of Low Earth Orbit (LEO) satellites, which have a lot less lag and better bandwidth availability. These satellites are deployed as Dense Small Satellite Networks (DSSN), across the globe, covering a large fraction of our planet at any given time.
These satellite networks have many advantages in telecommunications. Their most crucial benefit is extending coverage to areas that are otherwise difficult to cover with land infrastructure. They also provide low-latency transmission as compared to satellites in higher orbits. There is an exponential increase in the number of connected devices. Satellites can be deployed alongside ground infrastructure to support a massive number of devices. Satellite networks can provide the data rate and bandwidth requirements in areas where there is a sudden increase in network traffic and the ground infrastructure becomes loaded. Satellite networks also complement GPS systems to provide accurate locations for location-based services and can be used to cache data for reducing latency.
LEO satellites do not have a stationary footprint on the ground. Therefore, to use them in telecommunications, the satellite network infrastructure needs to be carefully planned. Satellites could form a constellation with identical satellites or clusters with non-identical satellites performing different functions. The orbital pattern of the satellites could be set as polar, rosette or hybrid. The inter-satellite communication could be based on radio frequency links, optical wireless communication links or visible light communication links. The satellite to ground contact could be either direct, could utilize a space or ground relay, or could be hybrid to utilize both types of relays.
Some technologies will aid the adoption of satellite networks in communications. Owing to the changing distances and positions between satellites, they should be fitted with intelligent, steerable, and high gain antennas. Multiple access techniques should be utilized for satellite networks where there should be provision to reuse frequency resources. Satellite networks are solar-powered, and their energy consumption characteristics are predictable because of known trajectories. Solar power optimization can be used to provide the required energy. To cater flexibility and advancement in network design and operation, satellites systems should be upgradeable to cater for new functionalities to be added remotely without changing the expensive hardware. Satellite network deployment should be optimized for resources such as capacity, power, latency and quality.

پاکستان میں ایک منظر اکثر دیکھا جاتا ہے کہ کسی ویران سڑک پہ دو تین لوگ گاڑی کو دھکا لگا کے پٹرول سٹیشن تک لے جا رہے ہوتے ہیں۔ عمومی طور پہ ایسا پٹرول اسٹیشن کے دور ہونے کی وجہ سے ہوتا ہے۔ تاہم غور طلب بات یہ ہے کہ بظاہر بے ضرر نظر آنے والا یہ منظر کسی بھی ناخوشگوار واقعہ کا پیش خیمہ بن سکتا ہے۔ برقی توانائی کے حالیہ افراط سے وطنِ عزیز میں جہاں بجلی سے چلنے والی گاڑیوں کی آمد کی بازگشت ہے ، وہیں یہ تشویش بھی پائی جاتی ہے کہ ان گاڑیوں کے چارجنگ اسٹیشن کہاں لگائے جائیں گے؟
لمز میں ڈاکٹر نوید ارشد اور انکی ٹیم نے اس تشویش کو بروقت زیرِ غور لانے کے بعد اپنی ٹیم کو ٹریفک انتظامیہ کے مختلف دفاتر میں بھیجا تاکہ وہاں سےٹریفک کے بہاؤ سمیت دیگر متعلقہ اعداد و شمار اکٹھے کیے جا سکیں۔ تمام اعداد و شمار کا تجزیہ، اور موٹر وے کا سروے کرنے کے بعد لمز کی ٹیم نے کُل ۸۵ ایسے مقامات کا تعین کیا گیا جو ہر لحاظ سے چارجنگ اسٹیشن کے لیے موزوں ثابت ہو سکیں گے۔ اعداد و شمار کے مطابق آغاز میں ان میں سے پندرہ کو ترجیحی بنیاد پر قائم کیا جانا چاہیے۔ تحقیق کے مطابق اگر ان پندرہ مقامات پہ دس تیز رفتار چارجر لگائے جائیں تو وہ پاکستان کے بڑے شہروں تک رسائی کی بنیادی ضرورت کو پورا کر سکیں گے۔
لاہور- اسلام آباد موٹروے پرگاڑیوں کے حالیہ بہاؤ، سالانہ اضافے کی شرح اور نقل و حرکت کو مدِ نظر رکھتے ہوئے پانچ مقامات پہ چارجنگ اسٹیشن بنانے کی تجویز دی گئی ہے جس سے لاہور تا اسلام آباد جانے والی برقی گاڑیوں کی چارجنگ ضروریات کو کماحقہ پورا کیا جا سکے گا۔ یہاں یہ امر بھی قابلِ ذکر ہے کہ دن بھر گاڑیوں کے بدلتے ہوئے بہاؤ کے پیشِ نظر یہ تجویز دی گئی ہے کہ جن اوقات میں چارجنگ کی طلب بہت کم ہو تب ایک محرک چارجنگ سٹیشن مطلوبہ مقام تک بھیجا بھی جا سکتا ہے۔
ان چارجنگ اسٹیشنز کا قیام تاجر برادری کے لیے توجہ کا مرکز بن سکتا ہے جیسا کہ پٹرول ا سٹیشنز کے قریب ہوٹل،دکانات اور دیگر تجارتی مراکز کو فروغ ملتا ہے۔ یہ بھی تجویز کیا گیا ہے کہ یہ تمام کاروبار اپنے منافع کا ایک طے شدہ حصہ چارجنگ سٹیشن کو دیں جس سے چارجنگ سٹیشن کے مجموعی منافع میں اضافہ ہو گا جو اسے ملک میں مزید پھیلاؤ کا موقع دے گا تاکہ زیادہ سے زیادہ صارفین کو کم فاصلے اور کم نرخ پہ چارجنگ کی سہولت میسر ہو۔

Presenting the Elements
Story:
A smartphone like the one in your hands on which you are (perhaps) reading this text contains around 70 elements from the periodic table. Of these 70, Silicon, Aluminum, and Oxygen, Indium and Tin are the major components of the glass display and touchscreens. Likewise, the battery essentially contains Lithium, Cobalt, Oxygen, and Carbon. The study of recovery, properties, and uses of elements present in the periodic table is known as Inorganic Chemistry.
However, teaching and learning Inorganic Chemistry could be challenging as there are quite a lot of elements. For instance, the elements we just mentioned are just a few of the total 50 elements of the Main Group of the periodic table. Teaching and learning the chemistry of these elements systematically and engagingly demand innovative pedagogical methods.
While teaching the Main Group Chemistry module of Inorganic Chemistry to undergraduate students, Dr. Muhammad Zaheer, Assistant Professor at the Department of Chemistry and Chemical Engineering, came up with an idea. Students were assigned a project to make posters highlighting the chemistry of selected elements assigned to them. The specific task was to develop creative ways to transform the descriptive chemistry of elements into engaging visuals (graphics, charts, illustrations, and schemes). The students were provided with all necessary guidelines and repeated feedback on their posters.
The posters—put on display in the Hallway—were visited by an overwhelming number of faculty and students. The presenters explained their posters to the visitors and answered their questions. The participants also peer-graded other posters.
The students think that this activity was quite engaging and helped them prepare the Main Group Chemistry in a more fun way. It also boosted their interest in the subject, and they learned how to communicate science to others in a concise manner.
The poster activity was the first of its kind in the department. The best of the posters will be framed and displayed in the main lobby of the department.

Algebraic Geometry Tools in Systems Biology
Abstract:I will motivate and introduce some methods and concepts of algebraic geometry that are being used in recent years to analyze standard models in molecular biology. The algebraic theory of chemical reaction systems aims to understand their dynamic behavior by taking advantage of the algebraic structure inherent in the kinetic equations and does not need the a priori determination of the parameters, which can be theoretically or practically impossible. I will also point out some of the mathematical challenges that arise from this application.
Prof. Alicia Dickenstein will be talking about “Algebraic Geometry Tools in Systems Biology” on 25 October 2021 at 4pm PKST via Zoom. She is our esteemed speaker in the John Conway Spirited Seminar Series organized by the Department of Mathematics at SBASSE, LUMS.

Artificial Intelligence on the Sphere: Spatial Slepian Transform for Localized Variation Analysis
Abstract:Processing and extraction of information from the data defined on the sphere find applications in cosmology, geophysics, planetary sciences, 3D antenna radiation design, medical imaging, computer vision, virtual reality, wireless communication, acoustics and computer graphics, to name a few. To support spatially localized data analysis in these applications, we present spatial-Slepian transform (SST). We employ well-optimally concentrated Slepian functions, which are obtained as a solution of the Slepian spatial-spectral concentration problem of finding bandlimited and spatially optimally concentrated functions on the sphere, to formulate the proposed transform. Due to the optimal energy concentration of Slepian functions in the spatial domain, the proposed spatial-Slepian transform allows us to probe spatially localized content of the signal. Furthermore, we present an inverse transform to recover the signal from its spatial-Slepian coefficients, formulate an algorithm for fast computation of SST, and carry out computational complexity analysis. We compute the spatial variance of spatial-Slepian coefficients and conduct experiments to show that spatial-Slepian coefficients have better spatial localization than scale-discretized wavelet coefficients. We present the formulation of SST for zonal Slepian functions, which are spatially optimally concentrated in the axisymmetric polar cap region and provide an illustration using a bandlimited Earth topography map.
To demonstrate the utility of the proposed transform, we carry out localized variation analysis, in which we employ SST to detect hidden localized variations in the signal. We illustrate, through a toy example, that spatial-Slepian transform yields a much better estimate of the underlying region of hidden localized variations than scale-discretized wavelet transform.

Environment Friendly Aerospace Technologies for Pakistan
Abstract: Aero Engine Craft is developing contrail-free aero-engines for the reduction of global warming and to induce artificial rain during aircraft flight through on-board water recovery from fuel emissions; creating a vision of the future for the aviation industry whereby it can not only reduce aviation induced global warming but also adopt an approach to treat the fuel emissions as a resource. A revolutionary technology is employed that eliminates contrails at source and recovers water from fuel exhaust emissions as a net positive product. This is a true definition of a disruptive technology; a global first attempt to create water within the aero-engine from the exhaust plume during flight, carry it aboard and release it as rainfall prior to landing. Our product is a low cost alternative to aero-engine redesign, and offers revenue potential to the aviation industry while solving a crucial environmental challenge.

چھوٹی سی آشا، ذروں کو چھونے کی آشا - اسکیننگ الیکٹرون مایکروسکوپ پہ تین روزہ تربیتی مشق
انسانی عقل و دانش نے کئی مرتبہ سینکڑوں دریاؤں کو سینکڑوں کوزوں میں بند کرنے کی ہمّت کی ہے۔ لیکن کیا اسی کوزے میں پوری کائنات کو بھی بند کیا جا سکتا ہے یا نہیں؟ لگتا ہے کائنات میں تو یہ کام ازلوں سے جاری و ساری ہے، گویا ایک شاندار انجمن ہر ذرّے میں موجود ہے ،
دلِ ہر قطرہ میں ہے سازِ “اناالبحر”
قدرت کی فراست یقیناً بے مثال ہے! ان مخفی پرتوں سے پردہ اٹھانے کے لیے انسان کئی سو سالوں سے بے چین رہا ہے۔ ٹیکنالوجی میں جدت کے آنے سے ہمارا کام کافی حد تک آسان ہو چکا ہے۔ اس جدت کی ایک لازوال مثال اسکیننگ الیکٹرون مایکروسکوپ ہے, جس کی باریک بینی سے چھوٹے سے چھوٹا ذرّہ بھی چھپ نہیں سکتا۔
لمز کے اسکول برائے سائنس اور انجینئرنگ میں مرکزی لیب نصب ہے۔ یہ وہ جگہ ہے جہاں جدید ترین تحقیقی آلات کے گٹھ جوڑ سے تحقیق دان دن رات پیچیدہ تجربات کو سرانجام دیتے ہیں اور سحر آمیز نتائج حاصِل کرتے ہیں۔ یوں معلوم ہوتا ہے کہ انسان جب حقیقت کی کھوج میں مصروف ہو جاتا ہے تو ہر قسم کی سماجی و ثقافتی رکاوٹوں کو بالائے طاق رکھ کر دیگر متجسس اشخاص تک رسائی کرنے کی پوری کوشش کرتا ہے کہ،
مشرق سے ہو بیزار نہ مغرب سے حذر کر
فِطرت کا اشارہ ہے کہ ہر شب کو سحر کر
اس جستجو کا ایک مظہرحال ہی میں منعقد کی جانے والی تین روزہ تربیتی مشق کے دوران دیکھنے کو مِلا، جس میں مختلف تعلیمی و تحقیقی اداروں سے لوگوں نے شرکت کی۔
دراصل اس مشق میں اسکیننگ الیکٹرون مایکروسکوپ کے مختلف پہلوؤں کو قریب سے جانچا گیا۔ مایکروسکوپ کے پرزوں کی فعالیت سے لے کر نمونوں کو نصب کرنے کے جدید اور مؤثر طریقوں کا جائزہ لیا گیا۔ اس کے ساتھ ساتھ ہر نشست کے آخر میں شرکا کو بین الاقوامی سطح کے مائہ ناز سائنسدانوں کی گفتگو سے مستفید ہونے کا موقع مِلا۔ ان میں لمز سے ڈاکٹر سلمان نوشیر ارشد اور امریکہ سے ڈینیل فیفر شامِل ہیں۔
اس مشق میں کُل ۱۲ لوگ شریک ہوئے، جن میں پی-ایچ-ڈی اور ایم-فل طلبہ بھی شامل تھے۔ شرکا نے تربیتی مشق کے حوالے سے اپنے خیالات کا اظہار کرتے ہوے بتایا کہ یہ ورکشاپ اُن کے تکنیکی ہنر کو مزید نکھارنے میں موثر ثابت ہوگی۔ شرکا نے مرکزی لیب کےتحقیقی آلات کو باقاعدگی سے استعمال کرنے پر لمز کی قیادت کی دُور اندیشی کو سراہا۔ ان کا کہنا تھا کہ مستقبل میں اس نوعیت کی مزید تقریبات منعقد ہوتی رہنی چاہییں۔
شعبہِ طبعیات سے وابستہ ڈاکٹر عطاء الحق نے اس مشق کو ترتیب دیا اور ان کے دیگر ساتھی، بالخصوص ڈاکٹر مرتضیٰ سلیم، ڈاکٹر کمیل عباس اور سیّد زاجِف حسین نے ایک موثر لائحہ عمل کے تحت اپنی تکنیکی مہارت سے سب شرکا کو مستفید کیا۔
