description: Dragon fruit (Hylocereus undatus [Haw.] Britton and Rose) is one of the most nutritious and newly introduced fruit crops among the progressive farming community of India. It is a climbing vine cactus species which is originated in tropical and sub-tropical forest regions of Mexico and Central and South America. Though it belongs to Cactaceae it needs an adequate amount of water unlike other members of this family. The edible part of the dragon fruit is the fruit pulp which constitutes 70-80% of the ripe fruits. It is rich in Vitamin-C, Iron, Calcium, Phosphorus, and several other vitamins and minerals including a high amount of anti-oxidants. It can be processed into a range of industrial food products like juice, sherbets, jam, syrups, ice creams, yogurt, jelly, preserve, candy, and pastries. It is known to prevent colon cancer and diabetes, reduce cholesterol and high blood pressure, control high sugar levels prevent cancer and bleeding. Dragon fruit promotes dental health and neutralizes toxic substances such as heavy metals. It can be propagated easily through cuttings of the mature cladodes or branches. The use of rooting hormones can boost the formation of the root system of the cuttings. Concrete pillars are ideal for the support of the climbing cladodes as the economic life of dragon fruit is almost 20-25 years and a 3-4-year-old vine may weigh around 100 kg. The average market price of the fruit ranges between Rs. 350-400/kg with a very high demand in Indian and international market. The dragon fruit plants come into flowering after 15 months of planting under long day condition and it produces around 5-7 flushes per year depending upon the climate and growing region.

description: Recent research in fast-multipole algorithms for the Helmholtz equation has yielded approximation algorithms that compute matrix vector products of specific matrices to any specified accuracy in linear time. A first purpose of this thesis is to combine this with recent research in randomized algorithms that has developed fast ways to compute rank-k SVDs of an M × N matrix. This combination yields an approximate SVD in O(k max(M,N)) time. We demonstrate this and explore its use in developing a novel scattered-data interpolation algorithm in three dimensions. Sinc functions are widely used in one dimension, especially in signal processing. We explore the use of these functions in three dimensions. A first exploration is their ability to accurately interpolate some standard functions. We find that the width parameter plays an important role in this regard, and suggest a prescription for its selection. As with other RBF interpolation algorithms, interpolating N points requires the solution of a dense linear system, which has O(N3) cost. We explore two uses of the fast randomized SVD to reduce this cost. First, we use the approximate randomized SVD to come up with a solution to the linear system. Next, we use a preconditioned Krylov iterative method (GMRES) with a low rank SVD as a preconditioner. Results are presented, and the method is found promising.

description: Recent molecular phylogenetic studies of the insect order Lepidoptera have robustly resolved family-level divergences within most superfamilies, and most divergences among the relatively species-poor early-arising superfamilies. In sharp contrast, relationships among the superfamilies of more advanced moths and butterflies that comprise the mega-diverse clade Apoditrysia (ca. 145,000 spp.) remain mostly poorly supported. This uncertainty, in turn, limits our ability to discern the origins, ages and evolutionary consequences of traits hypothesized to promote the spectacular diversification of Apoditrysia. Low support along the apoditrysian “backbone” probably reflects rapid diversification. If so, it may be feasible to strengthen resolution by radically increasing the gene sample, but case studies have been few. We explored the potential of next-generation sequencing to conclusively resolve apoditrysian relationships. We used transcriptome RNA-Seq to generate 1579 putatively orthologous gene sequences across a broad sample of 40 apoditrysians plus four outgroups, to which we added two taxa from previously published data. Phylogenetic analysis of a 46-taxon, 741-gene matrix, resulting from a strict filter that eliminated ortholog groups containing any apparent paralogs, yielded dramatic overall increase in bootstrap support for deeper nodes within Apoditrysia as compared to results from previous and concurrent 19-gene analyses. High support was restricted mainly to the huge subclade Obtectomera broadly defined, in which 11 of 12 nodes subtending multiple superfamilies had bootstrap support of 100%. The strongly supported nodes showed little conflict with groupings from previous studies, and were little affected by changes in taxon sampling, suggesting that they reflect true signal rather than artifacts of massive gene sampling. In contrast, strong support was seen at only 2 of 11 deeper nodes among the “lower”, non-obtectomeran apoditrysians. These represent a much harder phylogenetic problem, for which one path to resolution might include further increase in gene sampling, together with improved orthology assignments.

description: We consider a recently introduced generalization of the Ising model in which individual spin strength can vary. The model is intended for analysis of ordering in systems comprising agents which, although matching in their binarity (i.e., maintaining the iconic Ising features of `+' or `$-$', `up' or `down', `yes' or `no'), differ in their strength. To investigate the interplay between variable properties of nodes and interactions between them, we study the model on a complex network where both the spin strength and degree distributions are governed by power laws. We show that in the annealed network approximation, thermodynamic functions of the model are self-averaging and we obtain an exact solution for the partition function. This allows us to derive the leading temperature and field dependencies of thermodynamic functions, their critical behavior, and logarithmic corrections at the interface of different phases. We find the delicate interplay of the two power laws leads to new universality classes.

description: Statistical properties of a laser based on a one-dimensional disordered superlattice open at one side are studied numerically. The passive normal modes of the system are determined using the Feshbach projection technique. It is found that the mode competition due to the spacial hole burning leads to a saturation of the number of lasing modes with increasing pump rate. It is also responsible for nonmonotonic dependence of intensities of lasing modes as functions of pumping. Computed distributions of spectral spacing and intensity statistics are in qualitative agreement with experimental results.

Numerical Parametric Study of the Thermomechanical Effect of Encapsulation on a Welded Beam Lead Component
Creators: name: Akman, Josh

Year: 2014
Subjects: subject: Mechanical engineering
subject: FOS: Mechanical engineering

description: Encapsulation of components and assemblies has become widespread in the design of electronic products, providing protection from the environment and enhancing reliability. In this thesis, computational simulations are used to parametrically investigate the thermomechanical role played by the encapsulant when a beam-lead component is welded to slender copper busbars, encapsulated in a polymeric encapsulant, and subjected to temperature cycling. The parametric studies are conducted in two phases, using simplified two-dimensional finite element models.

In the first phase, a parametric design space is generated to systematically vary the encapsulant's thermomechanical properties, namely the Young's modulus and Coefficient of Thermal Expansion. A gull wing geometry is introduced into the lead of the component as a stress relief feature. In this case, a ramp thermal loading profile is used to understand the physics of this design and to provide relative comparisons between different combinations of the encapsulant's material properties within the design space. Response surface models are generated over the design space.

In the second phase, a Taguchi Design of Experiments (DOE) approach, based on orthogonal arrays, is used to analyze the effects of multiple design parameters under cyclic thermal loading. This includes encapsulant properties (a subset of the properties investigated in the first phase), encapsulant dimensions, lead geometry and dimensions, and busbar dimensions. Lead geometry is considered with and without stress relief features. The loading used in this phase is three temperature cycles between -40oC and 90oC.  The primary areas of concern (response variables) in both studies are the component lead and interconnect regions. Deformation and stress states in these critical regions are compared. Main factor effects and selected parameter interactions are computed in accordance with the Taguchi orthogonal arrays, to understand the dominant parameters and parameter interactions for cyclic thermomechanical stresses in this encapsulated assembly.
Promoting cultivation of underutilized horticultural species through a dedicated nursery: a success story from Andaman and Nicobar Islands, India

description: Andaman and Nicobar Islands are bestowed with rich phyto-diversity of horticultural significance. Out of 46,000 ha of cultivable land in the Islands, area under native perennial underutilized species is abysmal mainly due to lack of awareness and availability of their planting material. A dedicated nursery viz. Horticultural Plants Propagation Unit (HPPU) was established during 2019 in which nursery techniques were standardized for 15 native underutilized species and 33 species (including endemic and rare) are presently being multiplied. Within two years of its existence, HPPU has been a prominent source of planting material of underutilized species for local farmers, urban gardening enthusiasts, hoteliers, government and non government agencies, educational institutions, tribal and non-tribal afforestation activities. Visitors of HPPU are apprised about cultivation and utilization aspects of underutilized species being multiplied. To enhance the reach, awareness and plantation programmes are undertaken in collaboration with various stakeholders

description: Recent analyses of the WMAP data seem to indicate the possible presence of large-angle anisotropy in the Universe. If confirmed, these can have important consequences for our understanding of the Universe. A number of attempts have recently been made to establish the reality and nature of such anisotropies in the CMB data. Among these is a directional indicator recently proposed by the authors. A distinctive feature of this indicator is that it can be used to generate a sky map of the large-scale anisotropies of the CMB maps. Applying this indicator to full-sky temperature maps we found a statistically significant preferred direction. The full-sky maps used in these analyses are known to have residual foreground contamination as well as complicated noise properties. Thus, here we performed the same analysis for a map where regions with high foreground contamination were removed. We find that the main feature of the full-sky analysis, namely the presence of a significant axis of asymmetry, is robust with respect to this masking procedure. Other subtler anomalies of the full-sky are on the other hand no longer present.
description: 10 pages, 3 figeres. We performed a similar analysis of arXiv:astro-ph/0511666 by considering the LILC map with a Kp2 sky cut, and find that the presence of a significant axis of asymmetry is robust with respect to this masking procedure

description: We describe an intrinsic spin-Hall effect in $n$-type bulk zinc-blende semiconductors with topological origin. When electron transport is confined to a waveguide structure, and the applied electric field is such that the spins of electrons remain as eigenstates of the Dresselhaus spin-orbit field with negligible subband mixing, a gauge structure appears in the momentum space of the system. In particular, the momentum space exhibits a non-trivial Berry curvature which affects the transverse motion of electrons anisotropically in spin, thereby producing a finite spin-Hall effect. The effect should be detectable using standard techniques in the literature such as Kerr rotation, and be readily distinguishable from other mechanisms of the spin-Hall effect.

description: Radiation pressure can be used to enable optomechanical control and manipulation of the quantum state of a mechanical oscillator. Optomechanical interaction can also be mediated by photothermal effects which, although frequently overlooked, may compete with radiation pressure interaction. Understanding of how these phenomena affect the coherent exchange of information between optical and mechanical degrees of freedom is often underdeveloped, particularly in mesoscale high-power systems where photothermal effects can fully dominate the interaction. Here we report an effective theoretical model to predict and successfully reconstruct the dynamics of a unique optomechanical system: a cavity-enhanced setup for macroscopic optical levitation, where a free-standing mirror acts as the optomechanical oscillator. We decompose the photothermal interaction into two opposing light-induced effects, photothermal expansion, and thermo-optic effects. We then reconstruct a heuristic model that links the intracavity field to four types of cavity length changes caused by acoustic ($x_\textrm{ac}$), centre of mass ($x_\textrm{lev}$), photothermal ($x_\textrm{ex}$) and thermo-optic ($x_\textrm{re}$) displacements. This offers refined predictions with a higher degree of agreement with experimental results. Our work provides a mean to precisely model the photothermal effect of high power optomechanical systems, as well as for developing more precise photothermal modelling of photonics systems for precision sensing and quantum measurements.

description: Electron scattering experiments are powerful tools to study problems in nuclear physics. Recently, theorists achieved to extend ab initio calculations to medium-mass nuclei. The calculations can be verified with new electron scattering experiments. These experiments can reveal information about nuclear ground state properties (elastic scattering) as well as the dynamics inside the nucleus (quasielastic scattering). Furthermore, neutrino physics experiments need precise nuclear physics input. Due to the similarity between electrons and neutrinos, theoretical models and neutrino generators can be tested and improved.

description: One of the most fascinating experimental achievements of the last decade was the realization of Bose-Einstein Condensation (BEC) of ultra-cold atoms in optical lattices (OL's). The extraordinary level of control over these structures allows us to investigate complex solid state phenomena and the emerging field of ``atomtronics'' promises a new generation of nanoscale devices. It is therefore of fundamental and technological importance to understand their dynamical properties. Here we study the outgoing atomic flux of BECs loaded in an one-dimensional OL with leaking edges, using a mean field description provided by the Discrete Non-Linear Schrodinger Equation (DNLSE). We demonstrate that the atom population inside the OL decays in avalanches of size $J$. For intermediate values of the interatomic interaction strength their distribution ${\cal P}(J)$ follows a power law i.e. ${\cal P}(J)\sim1/J^α$ characterizing systems at phase transition. This scale free behaviour of ${\cal P}(J)$ reflects the complexity and the hierarchical structure of the underlying classical mixed phase space. Our results are relevant in a variety of contexts (whenever DNLSE is adequate), most prominently the light emmitance from coupled non-linear optics waveguides.

description: Social innovation (SI) is an ambiguous concept with multitude of definitions debated vigorously. While the primary impact of the definitional debate is on academic research, it also significantly shapes the scope and design of public policy. The motivation of this study is to analyse the correspondence of the different definitions of SI in social innovation practice and draw policy lessons. Through an extensive review of literature of the multitude of definitions and based on previous research, the researchers identify four overall components (objectives; actors and actor interactions; output; innovativeness) that the definitions use in different combinations. For the analysis it has been used the European Social Innovation Database (ESID), a comprehensive database of social innovation projects utilising machine learning and text-mining to collect data. ESID does not adopt a specific definition of SI but scores projects based on the four components mentioned above, which enables its users to construct a query based on a preferred definition. The researchers consider these components as different types of SI, each indicating to a set of specific features. Based on over 6,000 SI projects included in ESID, University of Strathclyde analyse the prevalence of these types of SI as well as their relationship with each other, geography and topics. The policy brief is supported by a web app (https://bit.ly/ESIDapp) which enables the reader to view the underlying data and interactively engage with the analysis.

description: We present an analysis of the pulsation behaviour of the Delta Scuti stars 7 Aql (HD 174532) and 8 Aql (HD 174589) -- a new variable star -- observed in the framework of STEPHI XII campaign during 2003 June--July. 183 hours of high precision photometry were acquired by using four-channel photometers at three sites on three continents during 21 days. The light curves and amplitude spectra were obtained following a classical scheme of multi-channel photometry. Observations in different filters were also obtained and analyzed. Six and three frequencies have been unambiguously detected above a 99% confidence level in the range 0.090 mHz--0.300 mHz and 0.100 mHz-- 0.145 mHz in 7 Aql and 8 Aql respectively. A comparison of observed and theoretical frequencies shows that 7 Aql and 8 Aql may oscillate with p modes of low radial orders, typical among Delta Scuti stars. In terms of radial oscillations the range of 8 Aql goes from n=1 to n=3 while for 7 Aql the range spans from n=4 to n=7. Non-radial oscillations have to be present in both stars as well. The expected range of excited modes according to a non adiabatic analysis goes from n=1 to n=6 in both stars.

description: The most massive haloes at high redshift are expected, according to hierarchical cosmologies, to reside in the most biased density fields. If powerful active galactic nuclei (AGN) are expected to exist anywhere in the early Universe (z>5), it is within these massive haloes. The most luminous of these AGN, powered by supermassive black holes (SMBHs) ~10^9Msun, thereby present an opportunity to test models of galaxy formation. Here, we present submillimetre (submm) continuum images of the fields of three luminous quasars at z>5, obtained at 850 and 450um using the Submm Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope (JCMT). N-body simulations predict that such quasars evolve to become the central dominant galaxies of massive clusters at z=0, but at z=5-6 they are actively forming stars and surrounded by a rich proto-filamentary structure of young galaxies. Our images show evidence of extended emission on a scale of ~100kpc from at least one quasar - indicative of a partially resolved merger or a colossal host galaxy. In addition, at >3sigma significance we detect 12 (5) submm galaxies (SMGs) at 850um (450um) in the surrounding fields. Number counts of these SMGs are systematically overabundant relative to blank-field submm surveys. Whilst the redshift-sensitive 850um/450um and 850um/1.4GHz flux density ratios indicate that some of these SMGs are likely foreground objects, the counts suggest that many probably lie in the same large-scale structures as the quasars.

description: We provide a description of the parity space reflection-time reversal (PT) operator acting on the two-dimensional polarization space of light represented by the linear algebra of Jones vectors and matrices. We establish the form of a PT-symmetric Jones matrix. We present two examples of laser resonators whose polarization eigenstates are described by PT-symmetric Jones matrices: one is based on the Faraday effect and a dichroic attenuation, while the other is made of twisted anisotropic mirrors. Both possess a control parameter that experimentally covers the exact, the broken PT-symmetry regions and their boundary, called an exceptional point, where the eigenstates of the resonator coalesce into a single state. The exact PT-symmetric region produces laser polarization modes emitting at the same frequency with different intracavity losses, while the broken PT-symmetric region features polarization modes emitting at distinct frequencies with the same intracavity losses. By applying unitary transformations, the concept of PT-symmetric Jones matrix is extended to matrices that commute with any antiunitary operator, thereby opening the prospect of a larger family of resonators geometries that also feature real or complex-conjugate spectra.

description: We develop an analytical method for studying the properties of a non-interacting Wormlike Chain (WLC) in confined geometries. The mean field-like theory replaces the rigid constraints of confinement with average constraints, thus allowing us to develop a tractable method for treating a WLC wrapped on the surface of a sphere, and fully encapsulated within it. The efficacy of the theory is established by reproducing the exact correlation functions for a WLC confined to the surface of a sphere. In addition, the coefficients in the free energy are exactly calculated. We also describe the behavior of a surface-confined chain under external tension that is relevant for single molecule experiments on histone-DNA complexes. The force-extension curves display spatial oscillations, and the extension of the chain, whose maximum value is bounded by the sphere diameter, scales as $f^{-1}$ at large forces, in contrast to the unconfined chain that approaches the contour length as $f^{-1/2}$. A WLC encapsulated in a sphere, that is relevant for the study of the viral encapsulation of DNA, can also be treated using the MF approach. The predictions of the theory for various correlation functions are in excellent agreement with Langevin simulations. We find that strongly confined chains are highly structured by examining the correlations using a local winding axis. The predicted pressure of the system is in excellent agreement with simulations but, as is known, is significantly lower than the pressures seen for DNA packaged in viral capsids.

Walking

description: On Sunday 13 November 2022, the Open Forest Collective (Andrea Botero, Markéta Dolejšová, Jaz Hee-jeong Choi, and Chewie the dog) hosted an experimental walk in Hyytiälä Forestry Field Station, also known as SMEAR II (Station for Measuring Ecosystem-Atmosphere Relations), in a Scots pine forest in Finland. Participants joined the walk in-person – in the cold and amber light of the winter afternoon – or over Zoom from multiple spaces and time zones. This story weaves together different perspectives of the walk, through patchy connections and distributed sensing.

description: Superconductivity with $T_{\rm c}$ $\simeq$ 2 K was discovered in the intermetallic binary compounds Rh$_2$Ga$_9$ and Ir$_2$Ga$_9$. This is the first observation of superconductivity in the Rh-Ga and Ir-Ga binary systems. Both compounds crystallize in a distorted Co$_2$Al$_9$-type structure (monoclinic, space group: $Pc$), which lacks spatial inversion symmetry. Specific heat measurements revealed that both compounds are weak-coupling BCS superconductors having an isotropic superconducting gap. Measurements in magnetic fields indicated type-I superconductivity with a critical field $H_{\rm c}(0)$ $\simeq$ 130 Oe for Rh$_2$Ga$_9$ and type-II superconductivity with an upper critical field $H_{\rm c2}(0)$ $\simeq$ 250 Oe for Ir$_2$Ga$_9$.

description: An essential attribute of many fractal structures is self-similarity. A Sierpinski gasket (SPG) triangle is a promising example of a fractal lattice that exhibits localized energy eigenstates. In the present work, for the first time we establish that a mixture of both extended and localized energy eigenstates can be generated yeilding mobility edges at multiple energies in presence of a time-periodic driving field. We obtain several compelling features by studying the transmission and energy eigenvalue spectra. As a possible application of our new findings, different thermoelectric properties are discussed, such as electrical conductance, thermopower, thermal conductance due to electrons and phonons. We show that our proposed method indeed exhibits highly favorable thermoelectric performance. The time-periodic driving field is assumed through an arbitrarily polarized light, and its effect is incorporated via Floquet-Bloch ansatz. All transport phenomena are worked out using Green's function formalism following the Landauer-Büttiker prescription.

description: The present study was conducted in the Badrinath holy pilgrimage in Western Himalaya. Lichen collected from seven localities (Badrinath, enroute Bhimpul to Vasudhara, Mana, enroute Vasudhara to Mana, Bhimpul, Vasudhara Glacier and enroute Vasudhara to Bhagirathi Glacier). The highest overall IVI (6.64) was recorded for Rhizoplaca chrysoleuca. The maximum number of lichens have been documented in Badrinath locality (139 spp.) while minimum (6) in enroute Vasudhara to Bhagirathi Glacier. The Badrinath has also express maximum 71 site specific species, while the Vasudhara Glacier has only 2 species. The dominance has been computed maximum (0.17) for enroute Vasudhara to Bhagirathi Glacier while, minimum for the Badrinath (0.01). The lowest Simpson Index value (0.83) has been recorded in enroute Vasudhara to Bhagirathi Glacier while the highest (0.99) in Badrinath. The lowest value of Berger-Parker diversity index (0.03), as well as the highest values of Brillouin, Shannon, Menhinick, Margalef and Fisher alpha diversity indices (7.20, 4.78, 8.03, 24.2 and 100.6 respectively) from the Badrinath locality, designates it as a site of highest species diversity. While enroute Vasudhara to Bhagirathi Glacier locality shows the highest value of Berger-Parker diversity index (0.17) as well as the lowest values of Brillouin, Shannon, Menhinick, Margalef and Fisher alpha diversity indices (1.75, 1.79, 0.35, 0.88 and 1.03 respectively). The value of evenness and equitability has been computed maximum (1.00) for enroute Vasudhara to Mana and Vasudhara to Bhagirathi Glacier localities, on the other hand, minimum (0.086 and 0.97 respectively) in the Badrinath.
Consumers' Perceptions of Organic Foods in Bangladesh: Challenges and Opportunities

description: This study aims at exploring the consumers' perceptions of organic foods. Additionally, this paper attempts to explore the existing problems to promote organic production. The significant issues include lack of awareness about organic technology and consumers’ trust in products and marketing systems. It is revealed that multi-factors influenced the choices of purchasing organic food. Educational qualification had a positive relationship with health and environmental awareness. However, there is a great potential to produce organic foods, particularly in a hilly region, and collect wild honey as organic foods from Sundarbans in Bangladesh. The cheaper wage is an opportunity for Bangladesh to intensify organic food production, generating decent jobs concomitantly. Lack of awareness, ecological consciousness, consumers' trust, certification, quality control mechanism, modern technologies, information literacy, storage capacity, and crop insurance were identified as the hindrances of flourishing the organic markets. In addition, the agricultural market chain is fragile, which is full of several intermediary groups. Furthermore, the availability of cheaper labor forces is a significant advantage of producing organic products that need intensive care.

description: Enterprise data lakes often suffer from substantial amounts of duplicate and redundant data, with data volumes ranging from terabytes to petabytes. This leads to both increased storage costs and unnecessarily high maintenance costs for these datasets. In this work, we focus on identifying and reducing redundancy in enterprise data lakes by addressing the problem of 'dataset containment'. To the best of our knowledge, this is one of the first works that addresses table-level containment at a large scale.
 We propose R2D2: a three-step hierarchical pipeline that efficiently identifies almost all instances of containment by progressively reducing the search space in the data lake. It first builds (i) a schema containment graph, followed by (ii) statistical min-max pruning, and finally, (iii) content level pruning. We further propose minimizing the total storage and access costs by optimally identifying redundant datasets that can be deleted (and reconstructed on demand) while respecting latency constraints.
 We implement our system on Azure Databricks clusters using Apache Spark for enterprise data stored in ADLS Gen2, and on AWS clusters for open-source data. In contrast to existing modified baselines that are inaccurate or take several days to run, our pipeline can process an enterprise customer data lake at the TB scale in approximately 5 hours with high accuracy. We present theoretical results as well as extensive empirical validation on both enterprise (scale of TBs) and open-source datasets (scale of MBs - GBs), which showcase the effectiveness of our pipeline.

Universality in the Large N_c Dynamics of Flavour: Thermal Vs. Quantum Induced Phase Transitions

description: We show how two important types of phase transition in large N_c gauge theory with fundamental flavours can be cast into the same classifying framework as the meson-melting phase transition. These are quantum fluctuation induced transitions in the presence of an external electric field, or a chemical potential for R-charge. The classifying framework involves the study of the local geometry of a special D-brane embedding, which seeds a self-similar spiral structure in the space of embeddings. The properties of this spiral, characterized by a pair of numbers, capture some key universal features of the transition. Computing these numbers for these non-thermal cases, we find that these transitions are in the same universality class as each other, but have different universal features from the thermal case. We present a natural generalization that yields new universality classes that may pertain to other types of transition.
