Abstract:
The origin of the differences in the water regime components of 0–0.6 m soil profile was identified in extensively managed permanent grasslands (PG, variants: once cut – 1C, twice cut – 2C, nocut – NC, mulched June – MVI, mulched July – MVII) using the method of the soil water balance (drainage lysimeters). The differences in the water regime of the experimental variants manifested themselves depending on adequate soil water storage in the period when the amounts of transpiring biomass in individual variants differed markedly: (i) at the beginning of the vegetation period, when the surface litter in the NC and 1C variants reduced the actual evapotranspiration (ETA), (ii) at the time of mowing and mulching (M), when these treatments (mainly M) increased the soil water supply by ca 10–20 mm per month and decreased the ETA values by 1–2.5 mm per day for about 2–4 weeks as compared to non-mown variants on the given date, and (iii) as a result of the presence of different agrobotanical groups with distinct transpiration intensity (leguminous plants with a higher transpiration intensity in the 2C variant compared to grasses). The post-M reduction in evaporation was compensated by a higher total transpiration resulting from an increase in the aboveground phytomass. The lowest water consumption with the highest supply to the groundwater resources was recorded in the NC and 1C variants. The 2C variant containing leguminous plants with high water requirements had the highest consumption of water for evaporation and the lowest amount of water runoff from the soil profile. The identification of the water regime differences in individual variants helped determine the appropriate PG management with the aim to increase the underground water levels in the protection zones of water resources. The 1C variant of management is recommended mainly in the source areas of groundwater with lower productivity soils. In the accumulation areas of water resources (floodplain areas) with a deep soil profile and highly productive grassland, the 2C variant is required; mulching, which would largely support the yielding capacity of grassland, should be avoided. Mulching may occasionally be used as a relatively suitable method for the sites with a low yielding capacity in the source area.

Abstract:
PURPOSE Genetic testing has clinical utility in the management of patients with hereditary cancer syndromes. However, the increased likelihood of encountering a variant of uncertain significance in individuals of non-European descent such as Asians may be challenging to both clinicians and patients. This study aims to evaluate the impact of variant reclassification in an Asian country with variants of uncertain significance reported in cancer predisposition genes. METHODS A retrospective analysis of patients seen at the Cancer Genetics Service at the National Cancer Centre Singapore between February 2014 and March 2020 was conducted. The frequency, direction, and time to variant reclassification were evaluated by comparing the reclassified report against the original report. RESULTS A total of 1,412 variants of uncertain significance were reported in 49.9% (845 of 1,695) of patients. Over 6 years, 6.7% (94 of 1,412) of variants were reclassified. Most variants of uncertain significance (94.1%, 80 of 85) were downgraded to benign or likely benign variant, with a smaller proportion of variants of uncertain significance (5.9%, 5 of 85) upgraded to pathogenic or likely pathogenic variant. Actionable variants of uncertain significance upgrades and pathogenic or likely pathogenic variant downgrades, which resulted in management changes, happened in 31.0% (39 of 126) of patients. The median and mean time taken for reclassification were 1 and 1.62 year(s), respectively. CONCLUSION We propose a clinical guideline to standardize management of patients reported to have variants of uncertain significance. Management should be based on the patient’s personal history, family history, and variant interpretation. For clinically relevant or suspicious variants of uncertain significance, follow-up is recommended every 2 years, as actionable reclassifications may happen during this period.

Abstract:
10583 Background: Genetic testing has demonstrated clinical utility in the identification and subsequent surveillance of patients with cancer predisposition syndromes. However, the increased likelihood of encountering a variant of uncertain significance (VUS) in individuals of non-European descent such as Asians may be challenging to both clinicians and patients in interpretation and management. VUS can be reclassified as more data becomes available. VUS reclassification is important, as it may have implications for surveillance and treatment. This study aims to evaluate the prevalence and patterns of variant reclassification in an Asian country and its impact on patient management. Methods: A prospective cohort of patients seen at the Cancer Genetics Service at the National Cancer Center Singapore between February 2014 to March 2020 was evaluated. The frequency, direction and time to variant reclassification was assessed by comparing the reclassified report against the original report. Results: A total of 1412 VUS were reported in 49.9% (845/1695) of patients. Over six-years, 6.7% (94/1412) of variants were reclassified. Most VUS (94.1%; 80/85) were downgraded to benign/likely benign variant, with a smaller proportion of VUS (5.9%; 5/85) upgraded to pathogenic/likely pathogenic variant. Actionable VUS upgrades and pathogenic/likely pathogenic variant downgrades, that resulted in management changes, happened in 31.0% (39/126) of patients. The median and mean time taken for reclassification were 1 and 1.62 year(s) respectively. Conclusions: Clinicians need to put in place a system for review of variants, as variant reclassification can lead to changes in management in nearly 1/3 of patients. Management should be based on the patient’s personal history, family history and variant interpretation. We propose a clinical guideline to standardize management of patients with VUS. For clinically relevant or suspicious VUS, follow-up is recommended every two years, as actionable reclassifications may happen during this period.

Abstract:
Abstract: Islamic banking (further referred to as the Bank) faces two significant problems: excessive concentration in Murabaha financing contracts and high cost of funds. These two classic problems directly impact the development of the Bank and give rise to the stigma of a less innovative and unprofitable industry. This research aims to make a new product breakthrough that can help stakeholders overcome the two problems above. Term Deposit Waqf Linked Isthisna (TDWLI) has 4 variants: TDWLI Perpetual Principal, TDWLI Perpetual Principal + Profit Sharing, TDWLI Periodic Principal, TDWLI Periodic Principal, and + Profit Sharing. The TDWLI Periodic Principal is the variant that is most ready to be applied because, in accounting terms, it has been regulated in PSAK 112. In general, this TDWLI product will provide several advantages for banks to reduce the cost of funds (especially in the main variant of Waqf only). It will increase Isthisna financing, referring to OJK data in 2019, only 0.3% of total financing. In terms of accounting treatment, PSAK 112 must be adjusted especially if the Bank will release a Perpetual-based product variant. The main problem with perpetual-based products is the uncommon features. In perpetual, cash waqf cannot be withdrawn or, in other words, eternal. This research recommends that OJK is expected to study this product more deeply to develop healthy and innovative Islamic banking.Abstrak: Perbankan syariah (selanjutnya disebut Bank) saat ini sedang menghadapi 2 masalah besar yaitu konsentrasi berlebihan di akad pembiayaan Murabaha serta tingginya Cost of Fund. Kedua masalah klasik ini berdampak langsung kepada perkembangan Bank dan memunculkan stigma industry yang kurang inovatif dan tidak menguntungkan. Penelitian ini bertujuan untuk membuat terobosan produk baru yang dapat membantu stakeholders dalam mengatasi kedua masalah diatas. Produk Deposito Waqf Linked Isthisna (DWLI) dengan 4 varian nya baik itu DWLI Perpetual Pokok, DWLI Perpetual Pokok + Bagi Hasil, DWLI Periodic Pokok dan DWLI Periodic Pokok + Bagi Hasil. DWLI Periodic Pokok menjadi varian yang paling siap untuk diaplikasikan karena secara akuntansi sudah diatur dalam PSAK 112. Secara umum produk DWLI ini akan memberikan beberapa keuntungan bagi bank dalam rangka menurunkan cost of fund (terutama pada varian Wakaf pokok saja) serta akan menaikkan pembiayaan Isthisna yang merujuk kepada data OJK tahun 2019 hanya 0,3% dari total pembiayaan. Secara perlakuan akuntansi, PSAK 112 harus disesuaikan terutama apabila Bank akan merelaisasikan varian produk berbasis Perpetual. Permasalahan utama dari produk berbasis perpetual adalah ketidak umuman fitur dimana dalam perpetual, Wakaf uang tidak dapat ditarik atau dengan kata lain abadi. Rekomendasi dari penelitian ini adalah OJK diharapkan dapat mengkaji produk ini lebih dalam demi perkembangan perbank syariah yang sehat dan inovatif.Islamic banking (further referred to as the Bank) faces two significant problems: excessive concentration in Murabaha financing contracts and high cost of funds.

PurposeThis study responds to the call of Fader and Hardie for more research on buyer behaviour toward stock keeping units (SKU). This paper aims to examine whether different SKU‐based product variants appeal to buyers with different demographic characteristics.Design/methodology/approachThis study examines the product variants (such as size, formulation, type) of a range of brands in six consumer goods categories. The authors calculate and compare the market share of each variant within each demographic group. If a variant has a higher market share within a specific demographic group than the overall average, this indicates segmentation at the product variant level.FindingsThe findings show that there are many differences in the market shares of product variants among different demographic groups of buyers. The largest differences are found extensively within the age and employment status variables.Originality/valueFunctionally different product variants tend to draw different demographic‐based segments of buyers, which has not been previously shown.

Abstract:
Field experiments were conducted in the maize-growing region on heavy gleic fluvisol from 1974 to 2000. Three variants of straw management (straw harvested, incorporated into soil and burned), two variants of soil tillage (conventional plough tillage to 0.22 m, shallow disc tillage to 0.12&ndash;0.15 m) and three variants of fertilization (30, 60 and 90 kg N.ha<sup>&ndash;1</sup>) were studied. After conventional tillage, the highest yield was obtained in the variant with burned straw (5.50 t.ha<sup>&ndash;1</sup>), followed by the variant with straw incorporated into soil (5.40 t.ha<sup>&ndash;1</sup>) and the lowest after harvested straw (5.01 t.ha<sup>&ndash;1</sup>). At shallow tillage, lower yields were assessed in all variants of straw management in comparison with conventional tillage (after straw burning 5.07 t.ha<sup>&ndash;1</sup>, incorporation into soil 4.66 t.ha<sup>&ndash;1</sup> and harvest 4.54 t.ha<sup>&ndash;1</sup>). The ranking of variants was identical to that in inversion tillage; however, the yield increased more after straw burning in comparison with its incorporation into soil. Yields increased regularly along with increasing rates of nitrogen. If long-term effects of straw incorporation on yields and yield trends were evaluated (in comparison with straw harvest), statistically significant decrease in yields was assessed after shallow in contrast with increase in yields after deeper straw incorporation.

Abstract:
Abstract Experiments with soybean on heavy soils of East Slovak Lowlands were established in the years 2010–2012. The effect of mineral fertilisers and soil conditioner application on soybean’s yield using three tillage systems (minimum tillage (MT), conventional tillage (CT) and no tillage (NT)) was studied. Production costs and economic efficiency of crop management practices were evaluated. The influence of production year on soybean crop was significant in the order of 2011, 2010 and 2012. Statistical evaluation confirmed that the effects of CT and MT systems were more significant compared with NT system. No significant differences were found between the variants of the mineral fertiliser and conditioner application. Differences in the total cost of soybean cultivation, as measured between years, were not significant. Fertilisation variants with application of HUMAC agro and NPK generated the highest costs. On the other hand, the lowest costs were achieved at fertilisation variants with application of NPK alone. Comparing tillage variants, the CT system had the highest costs each year. Significant savings were achieved on MT and NT variants. During the experimental period, a profit was reached on all variants. Applying NPK alone, the highest profit was achieved in 2010 and 2012 using MT system and in 2011 with CT tillage. The variant b2 with PRP sol in the years 2010 and 2011 was the most profitable using NT system and in 2012 using MT. Variant with HUMAC agro was the most profitable in each year using MT. The lowest income threshold for zero profitability was calculated in 2012. Using CT farming techniques at NPK fertilisation variant b1 in 2012, the income threshold was 1.85 t/ha, at variant b2 PRP sol it was 2.10 t/ha and at variant b3 HUMAC agro it was 2.42 t/ha. At MT and NT systems, the income threshold values for zero profitability were lower.

Abstract:
The weed infestation was assessed in a field experiment at the Research Institute for Folder Crops Ltd., Troubsko near Brno in 2001−2004. Numbers of individual weed species were determined using a counting method on the area of 0.25 m2 in winter wheat stands within the 6-crop rotation (peas, winter wheat, spring barley, oilseed rape, winter wheat, winter wheat) in different variants of soil tillage and straw management. The highest weed infestation in all variants was found when winter wheat followed winter wheat. The highest number of weeds was assessed in the variant with stubble tillage to the depth of 0.12−0.15 m, planting with a precision drill and straw chopping. The lowest number of weeds was found in winter wheat after peas in the variant with incorporation of chopped straw using a tiller to 0.12−0.15 m and planting with a drilling combination, and in the variant where chopped straw was sprayed with the BETA-LIQ preparation, incorporation with a tiller to 0.12−0.15 m and planting with a drilling combination.

Abstract:
The rapid evolution of Next Generation Sequencing in clinical settings, and the resulting challenge of variant reinterpretation given the constantly updated information, require robust data management systems and organized approaches. In this paper, we present iVar: a freely available and highly customizable tool with a user-friendly web interface. It represents a platform for the unified management of variants identified by different sequencing technologies. iVar accepts variant call format (VCF) files and text annotation files and elaborates them, optimizing data organization and avoiding redundancies. Updated annotations can be periodically re-uploaded and associated with variants as historically tracked attributes, i.e., modifications can be recorded whenever an updated value is imported, thus keeping track of all changes. Data can be visualized through variant-centered and sample-centered interfaces. A customizable search function can be exploited to periodically check if pathogenicity-related data of a variant has changed over time. Patient recontacting ensuing from variant reinterpretation is made easier by iVar through the effective identification of all patients present in the database carrying a specific variant. We tested iVar by uploading 4171 VCF files and 1463 annotation files, obtaining a database of 4166 samples and 22,569 unique variants. iVar has proven to be a useful tool with good performance in terms of collecting and managing data from a medium-throughput laboratory.

The goal of this thesis is to understand the complexity of configuring and managing variants in Simulink, a model-based design tool that is used in different industries such as automotive, aerospace, and healthcare; and to simplify it by analyzing its capabilities and proposing different solutions using different modeling, workflow and visualization techniques. Models play a major role in system engineering. Model-based development methods have gained widespread adoption in the past two decades. Simulink has been used by thousands of engineers around the world to design and simulate engineering systems. Any improvement in Simulink directly simplifies engineers' workflows and enables them to achieve their tasks more efficiently and effectively. I have studied variability concepts and use cases of configurators in different domains such as (1) personal customization of products (mass customization), (2) choice navigation in retail, and (3) software and model-based design tools. This has enabled me to understand complexities of configurators in different domains, and learn how some of the complexities have been addressed or managed. I conclude that the variant support in Simulink lacks some capabilities to fully support variability for large real-world applications in industry. To improve Simulink variant configuration and management, I propose solutions based on "feature modeling" and "interactive configurator" concepts. Use of "Binary Decision Diagrams" is recommended to achieve higher runtime performance when using interactive configurators for large modular systems and large teams. Also, I propose different visualization techniques to enable model designers to understand variant relationships in the model, check whether they have modeled the variants properly, and help them to further modularize their systems.

Abstract:
The objective of this thesis is to develop generic assembly relations to support variant management to aid the product development for products as families. The advent of the buyers' market has encouraged manufacturers to offer products as families to meet customers needs for differentiation. This creates the corresponding need for representing the product and process variants in a way to support the assessment of impact of product variants. Through the study of literature and standards, the current status of product modelling and product family was captured. Existing models of product model have considered representation of products as one of a kind and do not have the necessary capability to incorporate the variation in production variants that is commonly seen in the assembly of families of product. A Generic Assembly Relations Model (GARM) has been developed to meet the requirements. The generic Bill-of-Material (GBQM) and generic Bill-of-Process (GBQP) have been introduced as a single formalism to represent the product and process variants. The proposed model supports the reuse of product/process variants through the Generic Assembly Relations and GBQM and GBQP. The integration is achieved by the generic relations which act as the bridge between product and process models. This research increases the understanding of how to model product and process in the product family environment. The GARM model works as a production support tool for the product family in the Concurrent Engineering environment. With the GARM model, different views of the requirements can be developed at an early stage; the designer can be supported with feedback information such as the change of product component and assembly process. The GARM model supports variant management to aid the product development for products as families. The impact of the product variant on assembly process can be evaluated through the model. It has been validated by illustrating how the data structure definition supports the evaluation of changes in product family assembly process definition when additional variants are added through an example from the Personal Computer industry.

Abstract:
The problem presented is how to handle encoded data for which the encodings or decodings change with respect to time, and which contains codes indicating that certain data is unknown, invalid, or not applicable with respect to certain entities during certain time periods. It is desirable to build a database management system that is capable of knowing about and being able to handle the changes in encodings and the missing information codes by embedding such knowledge in the data definition structure, in order to remove the necessity of having applications programmers and users constantly worrying about how the data is encoded. The experimental database management language DEFINE is utilized to achieve the desired result, and a database structure is created for a real-life example of data which contains many examples of time-variant encodings and missing information.

Abstract:
One of the tools a clinician has in disease diagnosis and treatment is genetic testing. To generate value in genetic testing, the link between genetic variants and disease must be discovered, documented, and shared within the community. Working with two existing genomic variation tools, Kafeen and Cordova, a new set of features referred to as Variant-Curation and Database Instantiation (Variant-CADI) was identified, designed, implemented and integrated into the existing Cordova system to unite data collection, management and distribution into one cohesive tool accessible through user interfaces. This eliminates the user needing specialized knowledge of the underlying implementation, data pipeline or data management to collect desired disease specific genetic variations. Using this tool, new disease-specific variation database instances have been initialized and created as demonstrations of the utility of these applications.

Abstract:
Twenty first century manufacturing is characterized by customer specific products. Customers expect greater differentiation in the products that companies offer to them, thus changing the whole landscape of production. Greater the variety of products being offered to customers, greater is the complexity of shop floor operations. This complexity is translated to all the operations in the shop floor including material handling and inventory control. To overcome this situation, many manufacturers have turned to “Lean Manufacturing” to gain a competitive edge in the market by reducing costs and improving productivity in all operations throughout the shop floor. Therefore, this purpose of this thesis is to analyze the material handling of a highly customized multi-variant product-based production system. The thesis represents a case study that was done at a caravan manufacturing company in Tenhult, Sweden. During the study, data was gathered from field notes, observations and multiple semi-structured interviews. The findings were analyzed with respect to a theoretical background which was generated through an extensive literature review that was carried out throughout the research. Our analysis was based on a systems approach where the findings were categorized into three dimensions that affect material handling and inventory control. These dimensions are warehouse management systems, culture, and production management, which contribute to successful implementation of lean into the material handling operations and inventory control. In conclusion, the results show that efficient material handling and inventory control can only be achieved by finding a synergy between technology, people and organization. Our results also show that soft issues like organizational culture and employee culture need to be addressed along with technological issues because only when an alignment between people, technology and business objectives and values is achieved, lean implementation can be successful. Our results also show the need for better supplier customer collaboration to reduce inventory levels and material handling operation.

Abstract:
Product structure is the key information widely used by various business activities performed at different departments and different stages. In the made-to-order environment, product structure representation becomes more complicated because each product can have many variants with slightly different constitutions to fulfill different customer requirements. In such a context, product structure management comes to two interrelated functions: family structure management and variant structure management. At the same time, these two functions need to be seamlessly integrated to ensure the consistency of a family structure and its variant structure. From the business process perspective, throughout the entire product lifecycle, different business activities look at product structure with different purposes. Some activities are carried out based on variants and deem individual variants as different products and some need to be performed based on an entire family. As such, it is imperative to develop a product structure model that is capable of flexibly representing product families and product variants to serve up different processes in a product lifecycle. In this paper, a product structure model based on a master-variant pattern is proposed. The model can explicitly represent common characteristics of a family and particular characteristics of individual variants. Moreover, the variant structure representation is built on the top of the family structure representation. As a result, it provides an effective means to synchronize two types of structures. It also makes product family and variant concepts transparent to various business processes so that effective support can be provided to processes integration in the made-to-order environment.

Abstract:
The rapid manufacture of a great range of variant products is gaining importance in global competition. Customers are increasingly demanding products which are matched to their specific requirements. The production of these customized variants gives a competitive advantage, but also leads to higher production costs. Almost every step in the process of making a product is capable of generating variants. A key element in variant management is to make the variants as late as possible in order to exploit economies of scale in the earliest stages of production and to minimize the complexity of production [9], [6]. The technique of the highly flexible final production stage consists in achieving a late emergence of variants by integrating the variant-specific manufacturing processes into the assembly stage. This means abandoning the conventional distinction between manufacture and assembly in favour of a division into a preliminary, variant-neutral production stage and a final production stage where the variants take shape. The final production stage includes all the processes that yield variants. The complete manufacture of variant-neutral parts and subassemblies takes place in the preliminary production stage, as does the prefabrication of those parts and sub-assemblies which are to undergo final manufacture as variants in the final production stage. The result is a procedure capable of producing a broad spectrum of variants economically and with minimal throughput times. This paper describes the philosophy of this new approach and concludes with a practical case study.

Full text
Abstract:
We measure the contribution of firm-embedded productivity to cross-country income differences. By firm-embedded productivity we refer to the components of productivity that differ across firms and that can be transferred internationally, such as blueprints, management practices, and intangible capital. Our approach relies on micro-level data on the cross-border operations of multinational enterprises (MNEs). We compare the market shares of the exact same MNE in different countries and document that they are about four times larger in developing than in high-income coun-tries. This finding indicates that MNEs face less competition in less-developed coun-tries, suggesting that firm-embedded productivity in those countries is scarce. We propose and implement a new measure of firm-embedded productivity based on this observation. We find a strong positive correlation between our measure and output per worker across countries. In our sample, differences in firm-embedded productivity account for roughly a third of the cross-country variance in output per worker.
