A Path to Truthful Living (A Way of Life based on Guru Nanak's Panj Khand of Jap Hymns) AUTHOR: Dr. D. P. Singh; REVIEWER: Dr. H.S. Virk
No full textDr. D.P. Singh is a brilliant Physicist by training, a practicing Gursikh, and a dedicated researcher of Science and Sikhism. I was wondering how a physicist would justify his new venture as the Director of the Centre for Understanding Sikhism? After reading his half a dozen books on the Sikh religion, I am fully satisfied and testify that DP Singh is one of the best Sikh theologians in the Sikh world. He has not only imbibed the spirit of Sikhi based on the core principles of the Sikh scripture, Sri Guru Granth Sahib, but also interpreted its message for Sikhs in general and Sikh Youth in particular using scientific methodology. Dr. Bhai Harbans Lal, a celebrated Scientist and a Theologian himself, mentions briefly in the introduction that DP Singh deems it necessary to give a background of the contents of this book before the discussion of the main theme. He presents the main topics under discussion by DP Singh and elaborates on the social and cultural background in which Guru Nanak launched his revolutionary mission to reform society, which was riven by the decadent religiosity of his times. The author explains the purpose of writing “A Path to Truthful Living” in his Foreword: “This book is not a mere intellectual exercise or a scholarly treatise. It is a heartfelt exploration of Guru Nanak’s timeless teachings, presented in a way that seeks to touch the very core of our being”. The author further elaborates the central theme of his book: “The Panj Khands are five distinct domains of existence described by Guru Nanak in his profound compositions. Through the exploration of the Dharam Khand (Domain of Righteousness), Gyan Khand (Domain of Knowledge), Saram Khand (Domain of Endeavour), Karam Khand (Domain of Grace), and Sach Khand (Domain of Truth), we are encouraged to reflect on the nature of our thoughts, actions, and beliefs”
Book Review: "Mystic Echoes: Stories Rooted in Sikh Spiritual Realms" (Book Author: Dr. Devinder Pal Singh; Book Reviewer: Prof. Hardev Singh Virk)
No full textDr. Devinder Pal (DP) Singh joined the Physics Department in 1983 as an Ad-hoc Lecturer to teach Physics and complete his doctorate degree in Physics (Acoustics). I found him as a dedicated teacher and researcher. Upon moving to Canada as an immigrant, he initiated a new venture, the “Center for Understanding Sikhism”. A similar organization, the “Institute for Understanding Sikhism,” was established in 1999 by Dr. D. S. Chahal in Montreal. I was perplexed as to why a hardcore physicist was meddling in Sikhism. My curiosity was satisfied after reviewing his book, “Science and Sikhism: Conflict or Coherence.” I started rating him as one of the greatest exponents of Sikhism (Sikhi) in the modern age.
The Foreword “A Sacred Mirror: Seeing Ourselves Through Sikh Narratives” is by Bhai Harbans Lal, Ph.D., D. Litt (Hons). Bhai Lal appreciates the technique used by D. P. Singh: “It brings the living essence of Gurbani into our day-to-day existence. These are not abstract theological exercises, nor are they simply nostalgic tales of rural life. Instead, they are powerful spiritual parables, immersive narratives that reveal how the universal truths embedded in Sikh teachings manifest in the hearts, struggles, and transformations of everyday people”.
The author introduces his UNIQUE work in the Preface “Bridging the Temporal and the Timeless” as follows: “The stories in Mystic Echoes: Stories Rooted in Sikh Spiritual Realms emerge from the convergence of profound spiritual reflection, lived experience, and the enduring resonance of Sikh philosophy. They are not merely works of fiction, but narrative expressions of spiritual truths rooted in the teachings of the Sikh Gurus”. Further, D. P. Singh explains the relevance and importance of chosen topics: “Each story in Mystic Echoes is an attempt to explore a specific spiritual theme from within the Sikh tradition: Naam (Divine Name), Hukam (Divine Order), Haumai (Ego), Maya (Worldly Illusion), Raza (Divine Will), Sunn (Primal Void), Sahaj (Equilibrium), Bhaau and Bhae (Devotional Love and Reverent Fear), Nadar (Grace), Wismad (Wondrous Bliss), Anhad Naad (Unstruck Melody), Chautha Pad (Fourth State), Dasam Duar (Tenth Gate), Panj Tat (Five classical elements), and Daya (Compassion) among others

The replacement name is dedicated to G.S. Arora, author of the basic publication on the fauna of the Andaman and Nicobar Islands. Remark. The taxon tripunctata Reich, 1935 was described under the genus Lyclene. Here we transfer it to the genus Cyana and synonymize with C. detrita (see above). Thus, at present there are two Cyana taxa with the name tripunctata, so tripunctata Rothschild, 1936 becomes a junior secondary homonym of tripunctata Reich, 1935. Hence, we introduce the replacement name arorai nom. nov. for tripunctata Rothschild, 1936. Diagnosis. Forewing length is 12.5–15 mm in males and 17–18 mm in females. Cyana arorai is a polymorphic species, significantly variable in size. Cyana arorai is similar externally to C. carmina (Figs 13, 14), but differs by its arcuate antemedial line (that is oblique in C. carmina) and larger black discal spots. In females of C. arorai a third, posterior black spot may be developed (Figs 16, 17), what is unusual for the C. insularis group. The female genitalia of C. arorai are very similar to those of C. carmina (Figs 239, 240), but differ by the more heavily sclerotized cervix bursae having narrower longitudinal folds, and the lateral band-like signum being more weakly sclerotized subanteriorly with its anterior end strongly broadened. Distribution. Endemic of the Andaman Islands. The records of C. bianca (male) and C. coccinea (female) for the Andaman Islands (Hampson 1900; Draudt 1914; Arora 1983) belong to C. arorai.Published as part of Singh, Navneet, Volynkin, Anton V., Kirti, Jagbir Singh, Datta, Harvinder Singh & Ivanova, Maria S., 2020, A review of the genus Cyana Walker, 1854 from India, with descriptions of five new species and three new subspecies (Lepidoptera: Erebidae: Arctiinae: Lithosiini), pp. 1-93 in Zootaxa 4738 (1) on page 10, DOI: 10.11646/zootaxa.4738.1.1, http://zenodo.org/record/367243
Band Alignment and Electrical Investigations of Ultra-Thin Al2O3 on Si by E-beam Evaporation
No full textThe continuous downscaling leads the search of high-gate dielectrics. The films amorphous in nature offered good mechanical flexibility, smooth surfaces and better uniformity associated with low leakage current density. In this work, 16 nm thick amorphous Al2O3 films on silicon substrate are fabricated by E-beam evaporation. The high value of refractive index (1.76) extracted from ellipsometry analysis directs the deposition of compact film. The AFM analysis reveal a flat surface with small RMS surface roughness 1.5 angstrom. The band gap is extracted from O-1s electron loss spectra and was found 6.7 eV and band alignment of Al2O3/Si is derived from the UPS measurements. The films are incorporated in Metal Insulator -Semiconductor (MIS) capacitor to perform the electrical measurement. The flat band voltage (V-FB), dielectric constant () and oxide trapped charges (Q(ot)) extracted from high frequency (1 MHz) C-V curve are - 0.4 V, 8.4 and 2 x 10(11) cm(-2), respectively. The small flat band voltage - 0.4 V, narrow hysteresis and very little frequency dispersion suggest an exceptional good Al2O3/Si interface with small quantity of trapped charges in the oxide. The leakage current density was 4.27 x 10(-8) A/cm(2) at 1 V. The moderate dielectric constant and low leakage current density with ultra-smooth surface is quite useful towards its application in future CMOS and memory devices
Probing of Barrier Induced Deviations in Current-Voltage Characteristics of Polymer Devices by Impedance Spectroscopy
No full textTemperature dependent current-voltage measurements have been performed on poly(3-methylthiophene) based devices in metal/polymer/metal geometry in temperature range 90-300 K. Space charge limited current (SCLC) controlled by exponentially distributed traps is observed at all the measured temperatures at intermediate voltage range. At higher voltages, trap-free SCLC is observed at 90 K only while slope less than 2 is observed at higher temperatures which is quiet unusual in polymer devices. Impedance measurements were performed at different bias voltages. The unusual behavior observed in current-voltage characteristics is explained by Cole-Cole plot which gives the signature of interface dipole on electrode/polymer interface. Two relaxation mechanisms are obtained from the real part of impedance vs frequency spectra which confirms the interface related phenomena in the devic

Impact of Time-dependent Annealing on TiO2 Films for CMOS application
No full textPost-deposition annealing (PDA) is the inherent part of sol-gel fabrication process to achieve the optimum device performance, especially in CMOS applications. The annealing removes the oxygen vacancies and improves the structural order of dielectric films. The process also reduces the interface related defects and improves the interfacial properties. In this work, we have integrated the sol-gel spin-coating deposited high-TiO2 films in MOS. The films are fired at 400 degrees C for the duration of 20, 40, 60 and 80 min. The thicknesses of the films were found to be of similar to 30 nm using ellipsometry. The (Al/TiO2/p-Si) devices were examined with current-voltage (I-V) and capacitance-voltage (C-V) at room temperature to understand the influence of firing time. The C-V and I-V characteristic showed a significant dependence on annealing time such as variation in dielectric constant and leakage current. The accumulation capacitance (Cox), dielectric constant (kappa) and the equivalent oxide thickness (EOT) of the film fired for 60 min were found to be 458 pF, 33, and 4.25nm, respectively with a low leakage current density (1.09 10(-6) A/cm(2)) fired for 80 min at + 1 V
