Biomass‐Derived Materials for Interface Engineering in Organic/Perovskite Photovoltaic and Light‐Emitting Devices
Compared to their inorganic counterparts, organic optoelectronic devices receive considerable attention due to their lower cost, mechanical flexibility, bandgap engineering, and solution processability. In particular, achieving sustainability in solar cells and light emitting devices is an important milestone in the development of green electronics. This has facilitated a close collaboration between different technological fields, opening new ways for low-cost production and application of biomaterials. Recently, biomass materials, mainly derived from plants, animals and microorganisms, have emerged as effective candidates to modify the interfacial properties, and thus enhance the performance, lifetime, and stability of organic solar cells (OSCs), perovskite solar cells (PVSCs), and organic light-emitting diodes (OLEDs). Compared to the commonly used synthetic interfacial materials, the use of biomass interlayer materials (BIMs) is still in its embryonic stages; however, their nontoxicity, biorelevance, sustainability, special proton conductivity, and rich functional groups are stimulating researchers around the globe to fabricate novel devices with improved efficiency. Herein, a comprehensive review of BIMs and their importance in next-generation optoelectronic devices is provided. A well-targeted comparison between the electrical and physical properties of different BIMs is provided, and how such characteristics improve the performance of three key optoelectronic devices: OSCs, PVSCs and OLEDs, is discussed
Politics and Exhaustion — with Asad Haider
Theorist and author Asad Haider joins Below the Radar to discuss questions he explores in his book, Mistaken Identity: Race and Class in the Age of Trump. Asad discusses how class dynamics cannot be separated from identity-driven movements. As well, he explores ideas of political exhaustion in the tradition of political theorists such as Sylvain Lazarus and Alain Badiou. In this interview, Asad interrogates the role of identity in politics and how it has been taken up in discourse — complicating the relationship between race and class in a context that has been defined by capital interests. Asad and Am discuss theoretical questions around frameworks for political organizing and solidarity across movements. He also speaks to our current moment as one of political exhaustion, where it\u27s difficult to mobilize transformative political change
محمودہ عثمان حیدر کا سفرنامہ"مشاہداتِ بلادِ اسلامیہ" کا تجزیاتی مطالعہ
Begum Mahmooda Usman was born in Nahoor, a town in the Bajnor district of the India sub-continent. Begum Mahmooda was the cousin of the famous Novelist Syed Sajjad Haider. She was married to Yaldram’s nephew Usman Haider, who worked in the Middle East. Therefore, Begum Mahmooda Usman spent a lot of time in tourism and wrote the travelogue Mushahidat-e-Islamia. In this article, an analytical study of the travelogue will be presented

Asadullah, Prof. Dr. Abdul Moid, Dr. Abdus Subuh Qasimi, Muhammad Shafi, Fazal Elahi, Khawaja Nur Elahi and S. V. Hussain. The early library developments are given for better understanding of the role of these leaders
Secure and Smart Supply Chains: Design, Traceability, and Transparency
Thanks to the Effat University for supporting this work under the grant number UC#9/12June2023/7.1-21(4)13.Mobile healthcare is an appealing approach based on the Internet of Medical Things (IoMT) and cloud computing. It can lead to unobstructed, economical, and patient-centric healthcare solutions. The key performance indicators of such systems are dimensionality reduction, computational effectiveness, low latency, and accuracy. In this context, a novel approach is devised for EEG-based schizophrenia, a severe mental disorder that adversely affects a person’s behavior and classification. A multichannel EEG recording with suitable granularity is required for precise analysis. It can increase exponentially the data dimensionality plus complexity and computational load. The proposed solution attains an interesting trade-off between dimensionality reduction plus computational effectiveness versus accuracy. It uses the penalized sequential dictionary learning (PSDL) that incorporates channel selection. First, PSDL learns a dictionary from the input data and evaluates its performance on all EEG channels. Based on this evaluation, a subset of six channels is selected for further training in the dictionary. The proposed PSDL algorithm then incorporates a penalty term that enhances the power of the learned dictionary on the selected channels. We evaluate the proposed approach on the multi-channel EEG dataset from the Institute of Psychiatry and Neurology in Warsaw, Poland. A performance comparison is also made with counterparts. The models’ performance depends on the EEG signals’ complexity. Therefore, we tried to make our models robust and straightforward, achieving appropriate performance with minimal computational cost. The proposed method reduces the dimension in two steps. First, the count of channels is reduced to 68.42%. In the second step, the kept information, 31.58% of channels, is further reduced to 83.75% using dictionary learning. The proposed framework secures a remarkable data dimension reduction and a lower computational cost and latency than the counterparts while attaining the sparse representation classification accuracy of 89.12%. These findings are promising and confirm the potential of investing in incorporating the proposed method in contemporary mobile healthcare solutions.Effat Universit

Parution : Najam Haider, "Shi'i Islam. An Introduction", août-sept.2014, Cambridge University Press.
Author: Najam Haider Publication planned for: September 2014 availability: available from September 2014 format: Paperback isbn: 9781107625785 Description During the formative period of Islam, in the first centuries after Muhammad's death, different ideas and beliefs abounded. During this period two particular intellectual traditions emerged, Sunnism and Shi'ism. Sunni Muslims endorsed the historical caliphate, while Shi'i Muslims, supporters of 'Ali, cousin of the Prophet and the fourth cal..
Book Review: negotiating in civil conflict: constitutional construction and imperfect bargaining in Iraq by Haider Ala Hamoudi
Iraq has been racked by ethnic and sectarian conflict, which intensified following the American invasion and continues today. In this book, Haider Ala Hamoudi explores how the country was able to draft a constitution that appeals to the country’s three main sects despite their deep disagreements. Illuminating the aims of the text and acknowledging the continued discussions after a constitution is ratified, the author emphasises the ‘negotiation’ in Negotiating in Civil Conflict, writes Ruth Houghton

The Pilot-Judgment Procedure of the European Court of Human Rights.
Structural human rights deficiencies in the member states of the European Convention of Human Rights have caused numerous individual applications to the European Court of Human Rights and are a considerable factor in the Court's persistent overload crisis. The Pilot-Judgment Procedure was devised to tackle these structural deficiencies and has become an important instrument of the Court. Dominik Haider examines to which extent the Pilot-Judgment Procedure is reconcilable with the European Convention on Human Rights. After an analysis of the member states' obligations to resolve structural deficiencies, the author asks if the European Court of Human Rights is empowered to take the procedural steps which are characteristic of the Pilot-Judgment Procedure. In particular, the Court's express orders are critically scrutinised
