description: Over the past couple of decades, consumers have begun to increase purchasing of locally labeled products. However, research has shown their definition of local production is not always accurate and varies by product category. This study investigates consumers’ perceptions of the geographic boundary for local fruits/ vegetables and ornamental plants. A multinomial logit model is used to assess how consumers’ perceptions and perceived characteristics of local product attributes/factors (e.g. freshness, support local community, etc.) influence their understanding of geographic boundaries of local. Results are applicable to producers and retailers in their efforts to obtain portions of the local market. They are also pertinent to policy makers as they determine relevant regulations and definitions of local products.
Effect of metallicity on low mass X-ray binaries in globular clusters
Creators: name: Ivanova, Natalia
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose that the observed difference in the formation rates of bright low-mass X-ray binaries in metal-rich and metal-poor globular clusters can be explained by taking into account the difference in the stellar structure of main sequence donors with masses between ~0.85 Msun and ~1.25 Msun at different metallicities. This difference is caused by the absence of an outer convective zone in metal-poor main sequence stars in this mass range. In the result, magnetic braking, a powerful mechanism of orbital shrinkage, does not operate and dynamically formed main sequence - neutron star binaries fail to start mass transfer or appear as bright low-mass X-ray binaries.

Characterising the reactivity of metallic iron in Fe0/As-rock/H2O systems by long-term column experiments
Creators: name: Noubactep, C.
Publisher: name: FID GEO
Year: 2012

description: The intrinsic reactivity of four metallic iron materials (Fe0) was investigated in batch and column experiments. The Fe0 reactivity was characterized by the extent of aqueous fixation of in-situ leached arsenic (As). Air-homogenized batch experiments were conducted for 1 month with 10.0 g/ℓ of an As-bearing rock (ore material) and 0.0 or 5.0 g/ℓ of Fe0. Column experiments were performed for 2 and 3 months. Each dynamic experiment was made up of 2 glass columns in series. The first column contained 2.5 or 5.0 g of the ore material and the second column 0.0 or 5.0 g of a Fe0 material. Results showed no significant reactivity difference in batch studies for all 4 materials, ZVI2 was by far the most reactive material in column experiments. This observation was attributed to the relative kinetics of production of aqueous As and Fe species under the experimental conditions and their impact on the formation of a protective film on Fe0. Accordingly, no protective film could be built at the surface of the least reactive materials. The results corroborated the urgent need for unified experimental procedures to characterize Fe0 materials.

description: We introduce a simple stochastic system able to generate anomalous diffusion both for position and velocity. The model represents a viable description of the Fermi's acceleration mechanism and it is amenable to analytical treatment through a linear Boltzmann equation. The asymptotic probability distribution functions (PDF) for velocity and position are explicitly derived. The diffusion process is highly non-Gaussian and the time growth of moments is characterized by only two exponents $ν_x$ and $ν_v$. The diffusion process is anomalous (non Gaussian) but with a defined scaling properties i.e. $P(|{\bf x}|,t) = 1/t^{ν_x}F_x(|{\bf x}|/t^{ν_x})$ and similarly for velocity.

description: Food security and supply continuity have become main concerns of food companies and societies nowadays. To address these concerns, Jinzhong Food Co. Ltd. (hereafter abbreviated to Jinzhong) was one of the first Chinese meat companies to establish and integrate a pig production cooperative in 2005. Over the last decade or so, Jinzhong has successfully developed the cooperative to stabilize and improve the quality of pig supply, by building relationships with pig producers (farmers) and achieving an exceptional financial performance in the process. The company-led cooperative represents an innovative supply chain governance mechanism in a Chinese context. However, the pork industry has evolved significantly and the time has come for the senior management team at Jinzhong to decide whether or not to keep the cooperative. This case study is aimed at senior undergraduate students and postgraduate students specializing in agricultural economics/ agribusiness and can also be used for executive training for the management of food companies.
Reality as Resonance: Reconstructing the Cosmos from Field Dynamics
Creators: name: Neo Gomez
Publisher: name: Zenodo
Year: 2025

description: This deposit includes the paper “Where Models Meet: Uncovering the Inversion Point,” which introduces a framework for understanding how established cosmological models can be “right for the wrong reason.” It outlines the Inversion Point Principle, explaining why standard theories like Λ\LambdaΛCDM and General Relativity succeed in prediction yet rely on placeholders such as dark matter and dark energy. The paper proposes an emergent-field logic—inspired by the works of Emmy Noether, Karen Barad, Karl Friston, Mary Cartwright, Olga Taussky-Todd, and Karen Uhlenbeck—that reproduces lensing phenomena without invoking hidden mass. By showing how coherence dynamics underlie observed effects, it aims to refine (rather than replace) current models, underscoring deeper structural symmetries and phase relationships.

description: Metasurface optics have demonstrated vast potential for implementing traditional optical components in an ultra-compact and lightweight form factor. Metasurface lenses, also called metalenses, however, suffer from severe chromatic aberrations, posing serious limitations on their practical use. Existing approaches for circumventing such aberrations via dispersion engineering are limited to small apertures and often entails multiple scatterers per unit cell with small feature sizes. Here, we present an alternative technique to mitigate chromatic aberration and demonstrate high-quality, full-color imaging using extended depth of focus (EDOF) metalenses and computational reconstruction. Previous EDOF metalenses relied on cubic phase masks that induced asymmetric artifacts in images, whereas here we demonstrate the use of symmetric phase masks that can improve subsequent image quality, including logarithmic-aspherical, and shifted axicon masks. Our work will inspire further development in achromatic metalenses beyond dispersion engineering and open new research avenues on hybrid optical-digital metasurface systems.

description: In order to facilitate the transformation of African agriculture, Africa’s smallholders will require more and better access to input markets that deliver context-specific and well adapted innovations. This article summarizes the management lessons learned in developing supply chains for Purdue Improved Crop Storage (PICS) bags in West and Central Africa. PICS bags are hermetic grain storage bags that are leading a revolution in the post-harvest handling of grain on smallholder farmers in Africa. The bags have been very popular with farmers, but the major challenge has been developing supply chains to make those bags available for purchase at the village level. This article: (1) describes the PICS supply chain in West and Central Africa; (2) identifies constraints (i.e. financial, structural, social) that impede the development of the PICS supply chain; and (3) analyzes strategies used by businesses to expand distribution channels and increase bag sales.
Karbonatbänke mit Lithocodium aggregatum Elliott, Bacinella irregularis Radoicic ; Paläobathymetrie, Paläoökologie und stratigraphisches Äquivalent zu thrombolithischen Mud Mounds

description: Aus dem Unter-/Mittelalb von Nordspanien wird ein Profil mit bis zu 8 m mächtigen Lithocodium/ Bacinella Boundstones vorgesteUt. Die mikrofaziell-sedimentologische Analyse des Profils crgibt für die Lithocodium/ Bacinella Bänke eine bathymetrische Position vom tieferen Subtidal bis flachsten Subtidal/lntertidal. Die maximale Tiefenposition ist an die photische Zone gebunden, die wiederum durch das Ausmaß toniger Suspensionen beeinflußt wird. Die bathymetrische Obergrenze ist mechanisch kontrolliert (z.B. WeUenenergie, Tidenströme). Lithocodium/Bacinella ist zusammen mit anderen Algen/Mikroben ein charakteristischer Bestandteil thrombolithischer Mud Mounds (z.B. Gandara Mound). Die funktionelle Rolle von Lithocodium/Bacinella bei der Mud Mound Genese umfaßt Baffling und Binding, AutomikritProduktion durch Kalzifizierung innerhalb organischer Schleimhüllen und eine Mikritproduktion über intensive Bohraktivitäten an eingelagerten karbonatischen Hartteilen. Das massenhafte Auftreten von Lithocodillm/ Bacinella und diversen Algen/Mikroben kann mit einer längerfristigen Eutrophierung des Lebensraumes oder mit Schwankungen der Karbonat-Alkalinät des Meerwassers erklärt werden.
description: A section including Lithocodium/ Bacinella boundstones with a thickness of up to 8 m is reported from the Lower /Middle Albian of northern Spain. According to microfacies and sedimentological analyses the bathymetric position of the Lithocodium/ Bacinella banks ranges from deeper subtidal to shaUowest subtidal/intertidal conditions. The maximum depth is related to the photic zone, which ,itself is controled by the amount of muddy suspension. The upper bathymetric limit is mechanically defin'ed and corresponds to increased depositional energy (i.e. waves and tidal currents). Together with other algae and microbes Lithocodium/ Bacinella is a major constituent of thrombolitic mud mounds (Gandara mound). In the context of mud mound genesis the functional role of Lithocodium/ Bacinella includes baffling and binding, the production of micrite via the calcification inside of mucilagenous sheaths, and via intensive boring activities upon and inside of skeletal hardparts. The mass occurrence of Lithocodium/ Bacinella with associated algae and microbes may be explained by a longer ranging eutrophism of the environment or by shifts in seawater carbonate alkalinity.

description: We show how to properly gauge fix all the symmetries of the Ponzano-Regge model for 3D quantum gravity. This amounts to do explicit finite computations for transition amplitudes. We give the construction of the transition amplitudes in the presence of interacting quantum spinning particles. We introduce a notion of operators whose expectation value gives rise to either gauge fixing, introduction of time, or insertion of particles, according to the choice. We give the link between the spin foam quantization and the hamiltonian quantization. We finally show the link between Ponzano-Regge model and the quantization of Chern-Simons theory based on the double quantum group of SU(2)

Modern cryptic microbialite/metazoan facies from Lizard Island (Great Barrier Reef, Australia) formation and concepts
Creators: name: Reitner, Joachim
Publisher: name: FID GEO
Year: 1993

description: From shallow water caves of fringing reefs related to continental islands of the Lizard Island Section thrombolitic micritic microbialites were observed. The microbialites exhibit always a light decreasing facies succession. The succession starts with a coralgal community and ends with light independent microbial biofilms and benthos (coralline sponges). The sessile mineralized benthos community is constructed of crustose foraminifera, serpuli$, thecidean brachiopods, bryozoans, and coralline sponges. The observed benthic community is very similar 10 thoseone bbserved in cryptic habitates of Aptian and Albian reefs of northem Spain. For longtime studies of the m~crobialite formation and growth rates of coralline sponges the specimens were stained in vivo, within their natural habitat with histochemical fluorochromes and nonfluorescent agents. Main results are a very slow growth of the microbialite and associated sponges (50-100 Ilm/y). Only few calcifying microbes are participators during microbialite formation. Calcifying acidic organic macromolecules are mainly responsible for microbialite formation by cementing detritical material. FelMn-bacterial biofilms are responsible for strong corrosion of the microbialite. Beside the corrosive activity of the Fe/Mn-bacterial biofilms boring sponges (Aka, Cliona) are the main destructors. The investigations began in 1990 with a pilot study in fringing reefs of Lizard Island (Great Barrier Reef) and reefs of the outer barrier for comparison. Main goals are to study this environment under normal conditions and for comparison under controlled artificial conditions in seawater running aquaria. Two reef caves were selected for longtime research and all experiments were carried out within these caves. H.ZANKL(Marburg)hasrecentlyfoundnearly similar microbialites in cryptic habitates of reefs of St.Croix (US Virgin Islands, central Caribbean realm) (ZANKL 1993). Comparative fossil examples were studied by NEUWEILER (1993) on middle Albian reefs of northem Spain and KEupp et al. (this volume) for Jurassic ones. Both studies refer to the presented data. Purpose of this study is to demonstrate the growing procedure of a modem type of cryptic, light independent microbialite, the interaction with associated benthos, and its significance as a key facies to understandfossil metazoan-micriticl microbialitereefs. To understand these very complex processes it is neecessary to review and compile modem concepts of biomineralisation, biofilms, and e.g. the alkalinity question. Therefore mixing of own results and reviews is planned and intended! Main goal of this study is creation of a working hypothesis to understand the processes of formation of micritic/microbial build ups ("mud mounds"). Geochemically the observed microbiali tes are composed of mainly high-Mg calcites and exhibit high positive ö13C (+3 to +4) values.
Topologically protected Fano resonance in photonic valley Hall insulators

description: Rapidly developing photonics brings many interesting resonant optical phenomena, in which the Fano resonance (FR) always intrigues researchers because of its applications in optical switching and sensing. However, its sensitive dependence on environmental conditions makes it hard to implement in experiments. We in this work suggest a topologically-protected FR based on the photonic valley Hall insulators, immune to the system impurities. The topologically-protected FR is achieved by coupling the valley-dependent topological edge states (TESs) with one double-degenerate cavity. The $δ$-type photonic transport theory we build reveals that this topological FR dates from the interference of the two transmissions that are attributed to the parity-odd cavity mode and the parity-even one. We confirm that the induced Fano line shape of the transmission spectra is robust against the bending domain walls and disorders. Our work may provoke exciting frontiers for manipulating the valley transport and pave a way for the topologically protected photonic devices such as optical switches, low-threshold lasers, and ultra-sensitive sensors.

description: We discuss the possibility of flavor symmetries to explain the pattern of charged lepton and neutrino masses and mixing angles. We emphasize what are the obstacles for the generation of an almost maximal atmospheric mixing and what are the minimal ingredients to obtain it. A model based on the discrete symmetry $S_3$ is constructed, which leads to the dominant $μτ$-block in the neutrino mass matrix, thus predicting normal hierarchy. This symmetry makes it possible to reproduce current data and predicts $0.01\lesssimθ_{13}\lesssim 0.03$ and strongly suppressed neutrinoless $2β$-decay. Moreover, it implies a relation between lepton and quark mixing angles: $θ_{23}^q \approx 2(π/4-θ_{23})$. The Cabibbo mixing can also be reproduced and $θ_{13}^q\sim θ_{12}^qθ_{23}^q$. $S_3$ is thus a candidate to describe all the basic features of Standard Model fermion masses and mixing.

There has been a general increase in the number of publications, indicating that AE research has elicited more and more interest from scholars in different countries and across multiple disciplines. We have identified a number of themes and made sense of them by developing an integrated conceptual model, which consists of two parts: one for AE adoption at a firm level and one for AE development at a regional level. Furthermore, we recommend that more emphasis should be put on the regional development modes of AE and their impact in the developing world, as the practice is evolving rapidly in some developing countries such as China.

description: This paper proposes a template to assist food value chain actors in their collaborative efforts to develop common sustainable strategies and business models. Inspired by the simplicity of the Business Model Canvas, the template reintroduces sustainable practices as a support for management solutions for sustainable food value chains. The template requires cooperation between actors and stakeholders and comprises three steps: (1) identification of needs for sustainability; (2) development of value chain practices aimed to deliver sustainable value, and assignment of responsibilities to actors for these practices; and (3) formulation of a sustainable value proposition. The template also allows a simple graphical representation of sustainability in value chains, which helps improve communication between actors, and allows stakeholders to be kept informed. The template is applied to a sustainable pork value chain to illustrate how it captures various aspects of sustainability in the pork industry.

description: This study investigates how pricing and the representation of price (location of price sign, area of price number on price sign, extrinsic cue on price sign) influence consumer evaluation of nursery products. An incomplete orthogonal set of levels for each factor was used in a 35 factorial conjoint analysis. A web-based survey was conducted in March 2015. The results show the four factors account for 50.24% of the variance in plant preference, the other factor (plant type) accounts for the remaining 49.76%. Relative importance decreases from price level (16.15%) to cue (12.27%) to area (11.04%) and location (10.79%). Consumer’s purchase intention varies by demographics. The price level-purchase intention relationship also depends on cue. Benefit cue is more likely to offset the adverse effect of a price increase on purchase intention than feature cue, and the price level-purchase intention relationship for plants with feature/benefit cue appears to be inverted U shape.

description: In scenarios where a seller holds sensitive data $x$, like patient records, and a buyer seeks to obtain an evaluation of a function $f$ on $x$, solutions in trustless environments like blockchain fall into two categories: (1) Smart contract-powered solutions and (2) cryptographic solutions using tools such as adaptor signatures. The former offers atomic transactions where the buyer learns $f(x)$ upon payment. However, this approach is inefficient, costly, lacks privacy for the seller's data, and is incompatible with blockchains such as bitcoin. In contrast, the adaptor signature-based approach addresses all of the above issues but comes with an "all-or-nothing" guarantee, where the buyer fully extracts $x$ and does not support extracting $f(x)$. In this work, we bridge the gap between these approaches, developing a solution that enables fair functional sales while offering all the above properties like adaptor signatures.
 Towards this, we propose functional adaptor signatures (FAS), a novel cryptographic primitive and show how it can be used to enable functional sales. We formalize the security properties of FAS, among which is a new notion called witness privacy to capture seller's privacy, which ensures the buyer does not learn anything beyond $f(x)$. We present multiple variants of witness privacy, namely, witness hiding, witness indistinguishability, and zero-knowledge.
 We introduce two efficient constructions of FAS supporting linear functions based on groups of prime-order and lattices, that satisfy the strongest notion of witness privacy. A central conceptual contribution of our work lies in revealing a surprising connection between functional encryption and adaptor signatures. We implement our FAS construction for Schnorr signatures and show that for reasonably sized seller witnesses, all operations are quite efficient even for commodity hardware.

title: Geochronology and geochemistry of rare-element pegmatites from the Superior Province of Canada
Creators: name: Smith, Stephen Raymond
Publisher: name: The Open University
Year: 2001

description: The crystallisation age and thermochronology of late- to post-orogenic, rare-lithophile element (Li, Cs, Ta) pegmatites that are chemically associated with peraluminous granites have been determined from U-Pb TIMS and LA-MC-ICP-MS analyses of columbite-tantalite, and UV -laser 40Ar/39Ar analyses of mica.

In the northwest Superior Province, U-Pb ages reveal that the Pakeagama Lake pegmatite crystallised at 2673 ±8Ma. Rare-element pegmatites in the western Superior Province yield crystallisation ages of 2649 ±4Ma and 2644 ±8Ma for the Separation Rapids group, and 2665 ±lOMa for the Mavis Lake group, showing that they are temporally associated with adjacent peraluminous granites. Replacement zones of columbite-tantalite grains from the pegmatites show disturbance to the U-Pb system, probably caused by interaction with residual fluids and sub solidus metasomatic processes that lasted for -30Ma after crystallisation.

Mica from rare-element pegmatites is characterised by distinct compositional zoning with muscovite cores and F-, Li- and Rb-rich zinnwalditellepidolite rims. The zinnwalditellepidolite rims that replace the original muscovite were most likely precipitated from a residual melt or fluid phase during the late-magmatic to hydrothermal period of pegmatite formation.

Within these micas, 40Ar/39Ar apparent ages young towards the grain boundary and also towards the core - rim boundary, which suggests that the compositional zones form separate argon diffusion domains. However, similar 40Ar/39Ar apparent ages are found within F-rich zinnwaldite/lepidolite and coexisting muscovite indicating that diffusion rates may be comparable.

Mica from rare-element pegmatites of the Superior Province yield intra-grain 40Ar/39Ar apparent age variations of up to 800Ma within single crystals. Theoretical slow cooling models do not match the measured 40Ar/39Ar profiles and cannot account for the large apparent age variations. Thermal history models that produce the best fit to apparent age profiles include two re-heating events; a minimum 350°C re-heating at -2450Ma and circa 300°C re-heating at 1850Ma, both for a period of at least 10Ma. These apparent ages are concordant with two major Proterozoic events affecting the Superior Province; intrusion of the Matachewan - Hearst dyke swarms and the Trans Hudson Orogeny, respectively.

description: The aim of this study is to analyze the structures of land use in organic farming in the EU countries, for which EUROSTAT made the statistics available. The survey concerns the period between 2004 and 2012. The method of data clustering has been used there in order to classify the structure of land use. The taxonomic analysis allowed for differentiating 5 subgroups from the database. They have cross-sectional and time-series character as well as similar cropping patterns. The agricultural sector reacted to the increasing demand for organic products in two ways: by the extension of the crops’ acreage or by the change in the structures of land use (in order to match the product offer with the demand). However, the conducted surveys did not reveal the essential changes in the structures of land use. In consequence, a significant level of stabilization of supply’s structure was noted.

description: We propose a local strategy for constructing scale-free networks of arbitrary degree distributions, based on the redirection method of Krapivsky and Redner [Phys. Rev. E 63, 066123 (2001)]. Our method includes a set of external parameters that can be tuned at will to match detailed behavior at small degree k, in addition to the scale-free power-law tail signature at large k. The choice of parameters determines other network characteristics, such as the degree of clustering. The method is local in that addition of a new node requires knowledge of only the immediate environs of the (randomly selected) node to which it is attached. (Global strategies require information on finite fractions of the growing net.)

description: Changes taking place in the environment in which we live raise questions about the acceptable limits of economic and social development of the country, and specific controversy arises over ecological limits of development. The concept of bioeconomy may be treated as a response to emerging concerns. It is increasingly emphasized by European politicians and identified as the driving force of the development of various areas of the European Union. Bio-economy is defined for the needs of the European Union as the sustainable production of renewable biological resources (plants, animals, microorganisms), as well as their rational use in the production of food, feeds, industrial products and bio-energy. The aim of this paper is to present and evaluate the diversity of farm production in the region of Malopolska in the context of the development of bio-economy. The source data come from the National Agricultural Census for the years 2002 and 2010 and the General Statistical Office. The study used such research methods as horizontal and vertical analysis, cause and effect analysis, and tabular and descriptive analysis. The diversity of production structures in rural areas of the Malopolskie predisposes this area to give full effect to the principles of bio-economy within it. Despite many difficulties faced by the Malopolskie province agricultural producers, the potential of this area provides opportunities for development in many areas, directly or indirectly related to agriculture. Bioeconomy can be a solution to the low profitability of agricultural production, where this production (even from the smaller-sized households) will have an alternative, more profitable directions of use (eg. Energy production). Bio-economy, through focusing attention on the resources may in a particular way support and protect valuable natural areas, which are in large quantities located in the province. In the end, supporting food production will result in the maintenance of biodiversity in the world of plants and animals, and this is managed particularly well by small farms of the Małopolskie province, which avoid monocultures and excessive use of chemicals in agriculture. An indirect effect of the implementation of the concept of the bio-economy is the ability to create new workplaces for people who, moving away from agriculture, can find employment in rural areas outside the farms.

description: Computational social science studies often contextualize content analysis within standard demographics. Since demographics are unavailable on many social media platforms (e.g. Twitter) numerous studies have inferred demographics automatically. Despite many studies presenting proof of concept inference of race and ethnicity, training of practical systems remains elusive since there are few annotated datasets. Existing datasets are small, inaccurate, or fail to cover the four most common racial and ethnic groups in the United States. We present a method to identify self-reports of race and ethnicity from Twitter profile descriptions. Despite errors inherent in automated supervision, we produce models with good performance when measured on gold standard self-report survey data. The result is a reproducible method for creating large-scale training resources for race and ethnicity.

The passively mode-locked EDFL incorporates a CNT-based saturable absorber and has achieved a pulse width of 620 fs with a pulse repetition rate of 18 MHz. The spectral broadening phenomena inside each fiber has been observed with respect to the variation in seed pulse power. The SC spectrum bandwidth of 1050 nm, 1400 nm, and 2000 nm has been achieved using PCF, HNLF, and ZBLAN fiber respectively.

description: Rotating spiral waves without phase singularity are found to arise in a certain class of three-component reaction-diffusion systems of biological relevance. It is argued that this phenomenon is universal when some chemical components involved are diffusion-free. Some more detailed mathematical and numerical analyses are carried out on a complex Ginzburg-Landau equation with non-local coupling to which the original system is reduced close to a codimension-two parameter set.

description: Die auf den Balearen-Inseln Ibiza und Formentera weit verbreiteten quartären Kalksande, die bis in Höhen von >250 m ü. NN vorkommen, sind ausschließlich Windsedimente (Äolianite). Sie wurden teilweise festländisch umgelagert. Die Äolianite im Westen und Norden von Ibiza enthalten Foraminiferen, die bis in das Emilianum (Spätes Ältest-Pleistozän) zurückreichen. Die Kalksande wurden seit dem Emilianum in mehreren Zyklen während des älteren Pleistozäns angeweht. Die im Süden Ibizas und auf Formentera vorkommenden Äolianite stammen dagegen aus dem Jung-Pleistozän, auf Formentera ist eine Neotyrrhen-Strandterrasse in ihnen ausgebildet. An den Küsten Ibizas wurden keine herausgehobenen Strandterrassen beobachtet, die Insel zeigt bis in die Gegenwart hinein Anzeichen einer Absenkung.

description: We discuss the time development of Gaussian wave packet solutions of the quantum bouncer' (a quantum mechanical particle subject to a uniform downward force, above an impermeable flat surface). We focus on the evaluation and visualization of the expectation values and uncertainties of position and momentum variables during a single quasi-classical period as well as during the long term collapsed phase and several revivals. This approach complements existing analytic and numerical analyses of this system, as well as being useful for comparison with similar results for the harmonic oscillator and infinite well cases.

description: Raman enhancement techniques are essential for fundamental studies in light-matter interactions and find widespread application in microelectronics, bio-chemical sensing, and clinical diagnosis. Two-dimensional (2D) materials and their van der Waals heterostructures (vdWHs) are emerging rapidly as potential platforms for Raman enhancement. Here, we experimentally demonstrate a new technique of Raman enhancement driven by nonradiative energy transfer (NRET) achieving a $10$-fold enhancement in the Raman intensity in a vertical vdWH comprising of a monolayer transition metal dichalcogenide (1L-TMD) placed on a multilayer SnSe\tsub2. Consequently, several weak Raman peaks become visible which are otherwise imperceptible. We also show a strong modulation of the enhancement factor by tuning the spectral overlap between the 1L-TMD and SnSe\tsub2 through temperature variation and the results are in remarkable agreement with a Raman polarizability model capturing the effect of NRET. The observed NRET driven Raman enhancement is a novel mechanism which has not been experimentally demonstrated thus far and is distinct from conventional surface (SERS), tip (TERS) or Interference enhanced Raman scattering (IERS) mechanisms that are driven solely by charge transfer or electric field enhancement. The mechanism can also be used in synergy with plasmonic nanostructures to achieve additional selectivity and sensitivity beyond hot spot engineering for applications like molecular detection using 2D/molecular hybrids. Our results open new avenues for engineering Raman enhancement techniques coupling the advantages of uniform enhancement accessible across a wide junction area in vertical vdWHs.
