description: Buyer power and competition policy in food supply chains has emerged as an important economic issue and a highly sensitive item on the policy agenda all around the world. Claims that large retailers and food companies are depressing farm prices because of their market power have been made in many countries around the world (Swinnen and Vandeplas, 2009). Arising concentration of retailer sector increases the concern of existence and gradual growth of buyer power in this sector. The key reason is that the growing buyer power may have the effect of considerably distorting both retail and producer competition, and eventually it may damage economic welfare. In Finland, the increased concentration of the retail sector, with fewer outlets and the growth of the large supermarket chains, has been particularly fast. The two leading Finnish retail chains of food and daily goods increased their market share from 55 per cent in 1990 to nearly 75 per cent in 2008 (Niemi and Ahlstedt 2009).. The purpose of this paper is to investigate the possible existence of buyer power in Finnish food retail food industry. In details, we follow an approach used by Lloyd et al (2009) to measures oligopoly and oligopsony market power in the Finnish food retail industry. This offers a ‘first-filter’ test of price data that may be used as part of the preliminary analyses into the presence of buyer power in food markets. In practice, we apply a vector error correction mechanism (VECM) to perform two-stage tests: First is to test the hypothesis of cointegration between the supply and demand price indices with expected signs for the coefficients irrespective of the degree of retail competition; second is to test the null hypothesis of the perfect competition. The model also serves as a useful device for characterising how prices are transmitted in food market, albeit in simplified form.

description: Les filières viandes rouges en Algérie reposent globalement sur des élevages bovins et ovins, elles sont articulés à un marché interne fort rémunérateur, du fait du maintien de la demande à un niveau relativement élevé et de la faible élasticité de l’offre interne. Les structures de prix sont dominées par les marges prélevées par les réseaux privés de commercialisation. L'objectif de cet article est d'étudier le marché des viandes bovine et ovine, qui est mis en oeuvre essentiellement par des opérateurs. Le système de commercialisation de produits d’élevage et d’aliments de bétail est caractérisé par l’existence d’agents économiques qui sont éleveurs, maquignons et bouchers; ces opérateurs sont en contact permanent entre eux. L'information sur les prix et les quantités est parfaitement accessible à tous moment et à tous les opérateurs. Aucun opérateur par ces décisions ne peut seul faire évoluer le marché de façon significative, libre entrée, transparence, homogénéité du produit, atomicité de l'offre et de la demande.

description: Context. The increased detection rate of Fast Radio Bursts (FRBs) makes it likely to get samples of sizes $\mathcal{O}(10^2)$ to $\mathcal{O}(10^3)$ in the near future. Because of their extragalactic origin can help us in understanding the epoch of helium reionization. Aims. We try to identify the epoch of Helium II (HeII) reionization, via the observations of early FRBs in range of $z=3$ to $4$. Methods. We build a model of FRB Dispersion Measure following the HeII reionization model, density fluctuation in large scale structure, host galaxy interstellar medium and local environment of FRB contribution. The model is fit to the ideal intergalactic medium (IGM) dispersion measure model to check the goodness of constraining the HeII reionization via FRB measurement statistics. Conclusion. We report our findings under two categories, accuracy in detection of HeII reionization via FRBs assuming no uncertainty in the redshift measurement and alternatively assuming a varied level of uncertainty in redshift measurement of the FRBs. We show that under the first case, a detection of $N\sim\mathcal{O} (10^2)$ FRBs give an uncertainty of $σ(z_{r, fit})\sim0.5$ from the fit model, and a detection of $N\sim\mathcal{O} (10^3)$ gives an uncertainty of $σ(z_{r, fit})\sim0.1$. While assuming a redshift uncertainty of level $5-20\%$, changes the $σ(z_{r, fit})\sim0.5$ to $0.6$ for $N\sim 100$ and $σ(z_{r, fit})\sim0.1$ to $0.15$ for $N \sim 1000$ case.

description: The quantum bits (qubits) on which superconducting quantum computers are based have energy scales corresponding to photons with GHz frequencies. The energy of photons in the gigahertz domain is too low to allow transmission through the noisy room-temperature environment, where the signal would be lost in thermal noise. Optical photons, on the other hand, have much higher energies, and signals can be detected using highly efficient single-photon detectors. Transduction from microwave to optical frequencies is therefore a potential enabling technology for quantum devices. However, in such a device the optical pump can be a source of thermal noise and thus degrade the fidelity; the similarity of input microwave state to the output optical state. In order to investigate the magnitude of this effect we model the sub-Kelvin thermal behavior of an electro-optic transducer based on a lithium niobate whispering gallery mode resonator. We find that there is an optimum power level for a continuous pump, whilst pulsed operation of the pump increases the fidelity of the conversion.

In the gauge fixing method observables form a quotient Dirac bracket algebra. We show that these two algebras are isomorphic. A new realization of the observable algebras through the original Poisson bracket is found. Generators, brackets and pointwise products of the algebras under consideration are calculated.

The symbiosis between art and architecture as evidenced in Le Corbusier’s Ronchamp
Creators: name: Mueller, Linda M.
Publisher: name: University of British Columbia
Year: 2009

description: Le Corbusier was both artist and architect and the symbiosis between these dual roles contributed to his ability to think and create plastically. In order to understand the symbiotic nature of art and architecture in Le Corbusier's designs, a case study of the Chapel of N6tre-Dame-du-Haut at Ronchamp (1951-5), France, is presented that examines the influences and intellectual beliefs that contributed to the architect's works. To appreciate the symbiosis of art and architecture, as it is evidenced in this chapel built in the aftermath of World War II, it is also necessary to understand Le Corbusier's earlier experiences in these two endeavours. A literature review of the writings of critics and commentators central to our understanding of Le Corbusier's development and architectural philosophy illuminates the beliefs and experiences that contributed to his design ideals. Le Corbusier's sketches are considered, from his early drawings while studying with his mentor, L'Eplattanier, between 1902 and 1912, to his individual sketchbooks, which date from 1914, and other media contemporaneous with the chapel's construction during the 1950s, to ascertain the genesis of the design aesthetic that contributed to the plastic values of architectural projects such as Ronchamp.

description: For each integer k >= 2, we determine a sharp bound on mad(G) such that V(G) can be partitioned into sets I and F_k, where I is an independent set and G[F_k] is a forest in which each component has at most k vertices. For each k we construct an infinite family of examples showing our result is best possible. Our results imply that every planar graph G of girth at least 9 (resp. 8, 7) has a partition of V(G) into an independent set I and a set F such that G[F] is a forest with each component of order at most 3 (resp. 4, 6). Hendrey, Norin, and Wood asked for the largest function g(a,b) such that if mad(G) < g(a,b) then V(G) has a partition into sets A and B such that mad(G[A]) < a and mad(G[B]) < b. They specifically asked for the value of g(1,b), i.e., the case when A is an independent set. Previously, the only values known were g(1,4/3) and g(1,2). We find g(1,b) whenever 4/3 < b < 2.

description: We propose a new protocol of implementing continuous-variable quantum state transfer using partially disembodied transport. This protocol may improve the fidelity at the expense of the introduction of a semi-quantum channel between the parties, in comparison with quantum teleportation using the same strength of entanglement. Depending on the amount of information destroyed in the measurement, this protocol may be regarded as a teleportation protocol (complete destruction of input state), or as a $1\to M$ cloning protocol (partial destruction), or as a direct transmission (no destruction). This scheme can be straightforwardly implemented with the experimentally accessible setup at present.

description: We consider heterostructures consisting of regions with a continuous symmetry in contact with regions wherein the symmetry is spontaneously broken. The low-frequency dynamics of the corresponding order parameter are shown to induce nonequilibrium transport, a ``pumping,'' out of the symmetry-broken regions, which is governed by the generator of the broken-symmetry operator. This pumping damps Goldstone-mode excitations and transfers them beyond traditional (static) proximity length scales. Our general conclusions are discussed for specific examples of order parameters in helimagnets, charge/spin-density waves, superconductors, and ferromagnets. We carry out a detailed calculation of such pumping for spiral magnetic orders in helimagnets possessing a duality in the representation of its symmetry-broken states.

Kink-induced symmetry breaking patterns in brane-world SU(3)^3 trinification models

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The trinification grand unified theory (GUT) has gauge group SU(3)^3 and a discrete symmetry permuting the SU(3) factors. In common with other GUTs, the attractive nature of the fermionic multiplet assignments is obviated by the complicated multi-parameter Higgs potential apparently needed for phenomenological reasons, and also by vacuum expectation value (VEV) hierarchies within a given multiplet. This motivates the rigorous consideration of Higgs potentials, symmetry breaking patterns and alternative symmetry breaking mechanisms in models with this gauge group. Specifically, we study the recently proposed ``clash of symmetries'' brane-world mechanism to see if it can help with the symmetry breaking conundrum. This requires a detailed analysis of Higgs potential global minima and kink or domain wall solutions interpolating between the disconnected global minima created through spontaneous discrete symmetry breaking. Sufficiently long-lived metastable kinks can also be considered. We develop what we think is an interesting, albeit speculative, brane-world scheme whereby the hierarchical symmetry breaking cascade, trinification to left-right symmetry to the standard model to colour cross electromagnetism, may be induced without an initial hierarchy in vacuum expectation values. Another motivation for this paper is simply to continue the exploration of the rich class of kinks arising in models that are invariant under both discrete and continuous symmetries.

description: In this paper, I use a dynamic recursive computable general equilibrium to evaluate, for the economy of Senegal, the dynamic effects of an economic Partnership Agreement between West African countries and the European Union. In the simulation, the liberalization scheme is designed in a way similar to the interim agreement signed by Cote d’Ivoire and Ghana. The effects described are the shifts from the baseline numbers. I found that the production of agricultural goods will decrease, affecting employment negatively, particularly in unskilled labor, since this sector is very labor intensive. In fact, employment drops at around 0.2 percent a year, during the simulation period (2012-2030). GDP grows on average by 1.9 percent a year. The effects of the economic partnership agreement closely mirror the results of a free trade agreement between Senegal and the European Union, implying that a customs union between West African countries is not necessary to reap of the benefit of the former.
Different attentional mechanisms subserve the attentional blink and visual search

Publisher: name: University of British Columbia
Year: 2009

description: Joseph et al. (1997) found that a search task that was performed efficiently as a single task was impaired under dual-task conditions. This led to the claim that visual search is not performed preattentively. But that claim is questionable because different criteria (efficiency of visual search and mean level of performance) were used to assess attentional requirements under single- and dual-task conditions. In four experiments, I found that the two measures are affected in different ways by attentional manipulations and, therefore, represent different attentional processes. This finding questions the validity of the evidence used by Joseph et al. to substantiate the claim that all forms of visual search require attention.

description: Agricultural risks in our country have been introduced: firstly, disasters are multiple and frequently happened; secondly, widely affected and seriously suffered. Features of risks also are introduced: the first is the agricultural risk unit is large; the second is the agricultural risk is strongly regional; the third is the agricultural risk is universally half revival. The paper discusses the limits of the agricultural risks management, pointing out that in the management systems of agricultural risks, government finance is strongly burdened, compensations on the catastrophe is small in region, low in level. Based on the above analysis, the protection systems of agricultural risks have been constructed: the first is to establish the reassurance systems of agricultural risks; the second is to establish the risk funds of single agricultural item; the third is to transfer the catastrophe risks through stocks; the fourth is to construct multi leveled countermeasures of agricultural risks.

description: On the basis of describing the connotation of agricultural intangible asset and cost method, the technical ideas of appraising by cost method are introduced. The article analyzes the advantages (simple appraisal principle and easy to understand and grasp; overall consideration of various factors related to appraisal result value) and disadvantages (high appraisal cost; difficult to appraise and grasp various appraisal factors) of appraising by cost method. The article also summarizes the precondition of appraising by cost method: it is applicable to appraise the agricultural intangible asset which can be reproduced and afresh developed. Based on the cognition of agricultural intangible asset and the relevant rules of Ministry of Finance on appraisal of intangible asset by using cost method, the model of appraising agricultural intangible asset by cost method is constructed. That is: agricultural intangible asset value = replacement cost of agricultural intangible asset ×newness rate + opportunity cost of agricultural intangible asset. Determine and analyze parameters of the model, in order to offer references for appraisers to appraise agricultural intangible asset value more reasonably.

description: Aims: This Grounded Theory study aimed to capture the social processes involved in mothers’ decision-making around psychotropic medication. Method: Semi-structured interviews were conducted with 15 participants who were mothers who had been prescribed medication for mental distress when they had children below the age of 18 living with them. Results: Analysis via Grounded Theory found three processes informing medication use: Managing Conflicting Identities, Balancing Needs, and Seeking Integrated Care. Categories and subcategories capture how mothers tried to manage the conflicting identities of the perfect mother who copes and the stigmatised identity of medication user; how they made decisions around medication that allowed them to balance their own needs with the needs of their children; and how they sought collaborative care from professionals, and wanted their mothering taken into account in medication consultations. The study joins a growing body of research on the psychosocial motivations for medication decision-making, and demonstrates that mothering contributes complex relational and identity factors, including a consideration of the needs of potential future children. Implications: Recommendations are made about how maternal and mental health professionals might better meet mothers’ needs, including understanding their concerns about stigma and identity, the relational nature of their decision-making about medication, and the way they take desired future children into account in their medication decisions. Suggestions are made for future research with more diverse samples.

description: Increasing competitive pressures as well as growing requirements with regard to quality and safety pose a continuous challenge for farmers in European agrifood netchains. Against this background, the significance of network‐wide collaboration has been pointed out in recent years – especially for German livestock farming (Petersen et al., 2007). In the literature, it is generally agreed that participation in specialized networks can be beneficial to the competitiveness of individual farms and firms (Gellynck, Vermeire and Viaene, 2006). The northwestern part of Germany – known to be one of Europe’s major centres of pig production – apparently provides good structural preconditions for farms’ and firms’ comprehensive network participation due to an agglomeration of potential interaction partners specialized in pork production. Nonetheless, empirical studies show that, despite these good preconditions, farmers’ participation in networks is often limited. Spiller et al. (2005) for instance, found weaknesses with regard to relationship quality between pig fattening farmers and slaughterhouses. This might be due to power inequalities as well as manifold principal‐agent relationships in food supply chains characterized by information asymmetries and utility‐maximizing behaviour that limits cooperation between supply chain partners and reduces transparency of food supply chains (Theuvsen, 2004; Hingley, 2005; Deimel, Frentrup and Theuvsen, 2008).

Detection of high-degree non-radial pulsations in rapidly rotating bright A stars
Creators: name: Mkrtichian, David
Publisher: name: Zenodo
Year: 2024

description: Photometry from space (MOST, Kepler, Brite, TESS, etc.) has yielded revolutionary results in recent years in detecting pulsational modes in stars. However, due to the unresolved disks of stars, photometric observations are sensitive only to a narrow range of large-scale, low degree modes with $\ell \lt 5$. The pulsation spectrum of high-degree modes with $\ell \ge 6$ remains insufficiently detected and studied, posing a fundamental limitation in stellar seismology. Spectroscopic Doppler mapping of pulsations in rapidly rotating stars is currently one of the powerful but underutilized tools for detecting and identifying high-degree modes. Combining both space photometric and ground-based spectroscopic observations of stars can enable the detection of modes with degrees ranging from $\ell, m \sim 0$ to $\ell, m \sim 25$. I will present the first results of an ongoing high- and medium-resolution spectroscopic survey conducted on the 2m-class telescopes, aimed at detecting and identifying high-degree nonradial pulsations in a large sample of bright (V=2-6 mag) rapidly-rotating A2-F2 stars. I will discuss the techniques used and report on the detection and preliminary identification of high-degree prograde non-radial modes with degrees up to $\ell,m=20$ in a sample of 44 stars the majority of which have the TESS light curves. Additionally, I will discuss and provide a list of 50 candidate stars suspected based on data from the high-resolution spectroscopic archives that require further observations.

description: We present a model of a dusty disk with an inner hole which accounts for the Spitzer Space Telescope Infrared Spectrograph observations of the low-mass pre-main sequence star CoKu Tau/4. We have modeled the mid-IR spectrum (between 8 and 25 mic) as arising from the inner wall of a disk. Our model disk has an evacuated inner zone of radius ~ 10 AU, with a dusty inner ``wall'', of half-height ~ 2 AU, that is illuminated at normal incidence by the central star. The radiative equilibrium temperature decreases from the inner disk edge outward through the optically-thick disk; this temperature gradient is responsible for the emission of the silicate bands at 10 and 20 mic. The observed spectrum is consistent with being produced by Fe-Mg amorphous glassy olivine and/or pyroxene, with no evidence of a crystalline component. The mid-infrared spectrum of CoKu Tau/4 is reminiscent of that of the much older star TW Hya, where it has been suggested that the significant clearing of its inner disk is due to planet formation. However, no inner disk remains in CoKu Tau/4, consistent with the star being a weak-emission (non-accreting) T Tauri star. The relative youth of CoKu Tau/4 (~ 1 Myr) may indicate much more rapid planet formation than typically assumed.

description: Over the years, the pineapple export sector has been Ghana‟s best option for integrating her smallholders into the global economy. This was one of the primary objectives for the promotion of NTAEs under the SAPs. The sector guaranteed higher incomes for participating farmers and more foreign exchange for the national economy (Danielou & Ravry, 2005; Gatune et al, 2013). Over the years, however, participation of Ghanaian smallholders has been weakened, leading to dwindling fortunes for the national purse. This is mainly due to the acceptance and subsequent overthrow of the Smooth Cayenne in the European market by the MD2, which was Del Monte‟s strategy to outwit competitors through product and marketing innovations. The study sought to determine the current level of adoption of the MD2 variety by smallholders. Another objective of the study was to understand the constraint factors to adoption and production of MD2 by smallholders. The study employed a mixed research design technique to achieve its objectives. The study focused on smallholder pineapple farmers in the Nsawam Adoagyiri Municipal Assembly.. Results showed that there is a low rate of adoption of the MD2. However, those in the late adopter category formed the majority, and points to the possibility of restoring Ghana‟s position in the pineapple export sector if underlying constraints to adoption are addressed. Lack of access to finance, high cost of production and non-availability of plantlets were found to be the major constraints to adoption. The study recommends the provision of plantlets as well as cheap and flexible credit to smallholders to enhance adoption of the MD2.

description: In this paper we use a combination of behavioral and new institutional economic perspectives to look at the transactions of “sustainable‐oriented” foods (e.g. organic food, fair trade, etc.) which often assume the characteristic of credence goods. When credence attributes are involved in the transaction (e.g. safety, fairness, etc.) information asymmetry and uncertainty tend to reduce the likelihood of different parties to enter in the transaction1. Because spot markets are unlikely to be used in this type of transactions, typical solutions are the use of hybrids, vertical integration and public monitoring (Vetter and Karantininis, 2002; Ménard and Valceschini, 2005). Moreover both consumers and producers (e.g. farmers) look at these products from a more utilitarian (cold) then a hedonic (hot) perspective. In this paper we address this issue by analyzing the effect of a “new” governance structure (GS) which is emerging in credence food transactions both at local and global level. We define this GS as a community network (CN) in which consumers and producers strongly integrate their goals by organizing a “club”.

description: There always exists an entanglement witness for every entangled quantum state. Negativity of the expectation value of an entanglement witness operator guarantees entanglement of the corresponding state, given that the measurement devices involved are perfect, i.e., the performed measurements actually constitute the witness operator for the state under consideration. In a realistic situation, there are two possible ways of measurements to drive the process away from the ideal one. Firstly, wrong measurements may be performed, and secondly, while the measurement operators are implemented correctly, the detection process is noisy. Entanglement witnesses are prone to both of these imperfections. The concept of measurement-device-independent entanglement witnesses was introduced to remove the first problem. We analyze the "detection loophole" in the context of measurement-device-independent entanglement witnesses, which deal with the second problem of imprecise measurements. We obtain an upper bound on the entanglement witness function in the measurement-device-independent entanglement witness scenario, below which entanglement is guaranteed for given non-ideal detector efficiencies, that can involve both lost events and dark counts.

description: Farmers Markets are receiving an increasing attention by both food chains actors and social scientists. Economic and sociological studies are contributing to the comprehension of these forms of exchange. Both consumers and producers are fostering their expectations about the renewal of a mode of exchange which sustained local production‐ consumptions linkages. The main economic function of these organizational structures seems to be the reduction of the price paid by the consumers and the enhancements of allocation of farm products. The basic interpretation of these forms of exchange focuses on market structure, nonetheless the exchange relationships seems to emphasize several dimensions, including economic and cultural aspects. The objective of the paper is of investigating the role of networks among producers and consumers in structuring and making viable the Farmer Markets as structures of short food supply chains. The basic idea is that the strength of Farmer Markets is the ability of satisfying the consumers expectations about a few characteristics of the products, entailing given cultural and economic aspects. The study argues that under this view the Farmer Markets may be thought of as a emerging form of production‐consumption interaction. According to existing evidences it is suggested that the network is also the emerging forms of horizontal relationships among the producers participants to the markets. The paper aims at suggesting that basic types of trust act as key factor in structuring the networks and in promoting the stability of the market.

description: We report our search for variability in the H-alpha emission line of the recurrent novae T CrB with time resolution 10-15 minutes. This is comparable with the time scale of the photometric flickering observed in this object. This is the first time that observations of the short time scale variation in emission lines have been made in this object. On two nights (990106 and 990107) we detected statistically significant variability (at 0.99 confidence level) in the line profile of H-alpha. This variability is confined in the central part of the emission line (\pm 100 km/s) although FWZI(H-alpha) is ~800 km/s. The variability in the line profile is accompanied with variability of the total equivalent width, EW(H-alpha), \pm 8% for 990106, and \pm 6% for 990107 (calculated from the mean value of EW). Assuming Keplerian motion, the variability is generated at a distance ~20-30 R_Solar from the white dwarf, which is approximately the radius of the ring the stream of gas forms as it flows away from L_1. On three other nights we are only able to put upper limits on the variability, ΔEW(H-alpha) \pm 2% for 980415, \pm 4% for 980802, and \pm 3% for 980803.

’The bob-shingle regime that rules the feminine world’ : consumerism, women and work in 1920s British Columbia
Creators: name: Moore, Magdalena Dorothy Kean
Publisher: name: University of British Columbia
Year: 2009

description: This project is a case study of the hairdressing industry in British Columbia in the 1920s. It argues that gender divisions persisted as consumerism became increasingly important to British Columbians, and that despite British Columbia's sometimes challenging engagement with international consumerism, the province's economy remained remarkably synchronized with international trends. It tells the story of the rapid expansion and feminization of hair services markets and businesses; examines the public and legislative debates about the importance of consumer services such as hairdressing and its customers; and reveals the persistence of gendered divisions in the early transition to a consumer services society. Using British Columbian newspaper reports, American and Canadian women's and union periodicals, city directories, national censuses, and government reports, the project looks first at the increasing pressures in the 1920s from business owners, advertisers, and magazine editors to adopt new, fashionable hairstyles and the sources of ambivalence among women about the new styles. It then turns to hairdressing as a business and source of employment, and after briefly reviewing the history of hairdressing in North America looks at the rapid expansion of hairdressing businesses in British Columbia during the 1920s; the demographic characteristics of hairdressing workers and entrepreneurs; and the feminization of the hair services industry. It also explores the connection between feminist ideals and women's entrepreneurship in the hair services field. Finally, the hairdressers' attempt to gain regulation from the provincial government is examined at the end of the decade, with a particular focus on how consumerism and hairdressing, its workers and customers, are characterized. The legislative and public debates about hairdressing regulation reveal anxiety about consumerism and persistent gender divisions as British Columbia began to shift toward a consumer-oriented society. It concludes that British Columbia, despite its primary resource economic base, remained remarkably in step with international trends, from feminization of services to regulation of those services, of which hairdressing was just a beginning.

description: Several researches evaluated consumers’ Willingness To Pay (WTP) for each meat traceable attribute, generating a lot of information in this regard, although related to the conditions of each study. In light of this, WTP estimates for traceability characteristics largely differ across the literature, leading sometimes to contrasting interpretations. Seeking a full, meaningful statistical description of the findings of a collection of studies, the meta‐analysis allows us analyzing the consistency across studies and controlling for factors thought to drive variations in WTP estimates. The meta‐analysis has been conducted of 23 studies that, in aggregate, report 92 valuations for WTP.

description: We have examined the head-on collision of two electrons in approximation of coherent states. We have shown that the character of collision depends mainly on ratio of initial relative electron's momentum to momentum uncertainty of electrons. When this ratio becomes greater then 1, the Coulomb interaction does not practically influence the scattering.

description: Two new, extremely small land snail species, Angustopila coprologos Páll-Gergely, Jochum & Hunyadi n. sp. and Angustopila psammion Páll-Gergely, Vermeulen & Anker n. sp. are described from northern Vietnam and northern Laos, respectively. The former is characterized by a rough surface sculpture and bears tiny mud granules arranged in a pattern of radial lines on its shell surface. The latter species is the new global record-holder of the tiniest land snail title, with a shell width of 0.6–0.68 mm and a shell height of 0.46–0.57 mm. These measurements surpass the former records of Angustopila pallgergelyi and Acmella nana.
