Does Primary Stability Is Mandatory For Dental Implant Success? A Systematic Review Of Literature
Authors: A AlSamman Abdurrahman
Published: March 2022

Background: Implant primary stability is considered a prerequisite of implant osseointegration and ultimately, implant success. The prognosis of dental implants installed with low or without primary stability is still unclear. The aim of this systematic review was to assess the survival rate of implants placed with low/without primary stability and to diagnose risk factors that might affect outcomes of such implants.

Material and methods: Electronic search in the National Library of Medicine (MEDLINE-PubMed) was performed on articles published in English up to September 2020. The terms (MeSH words) used in the search were ‘Dental’ OR ‘Oral’ AND ‘Implant’ AND ‘Survival’ OR ‘Success’ AND ‘Stability’ OR ‘Low stability’ AND ‘Insertion torque’. In addition to the online databases of selected journals. Randomized and controlled clinical trials, cohort studies, case-control studies, and prospective or retrospective case series were included.

Results: Of the retrieved 386 publications, 24 studies met the inclusion criteria, with a total of 1632 implants, giving a survival rate of 96.32%. No statistically significant influence of the type and site of implantation on implant survival was recorded. A significant higher failure rate of immediately loaded implants that than those with delayed loading protocols.

Conclusion: Poor primary stability might not negatively affect the survival rates of non-immediately loaded dental implants.

Северный морской путь (СМП), как транспортный коридор, соединяющий западный и восточный регионы, начинает играть важную роль в экономике России. Объем перевозок по СМП имеет тенденцию к постоянному росту и продлению периода навигации. Создание крупнотоннажных судов высоких ледовых классов, при значительных размерениях превосходящих ширину современных ледоколов, меняет режим судоходства на трассах СМП. Поэтому, можно ожидать увеличения числа ледовых повреждений, как для новых судов, так и для имеющих значительный возраст эксплуатации. Хотя, правила постройки судов постоянно развиваются, введен в обязательную практику «Полярный кодекс», как глава Международной конвенции СОЛАС 74, тем не менее, многие вопросы, касающиеся работы балочных конструкций в составе бортовых перекрытий судов ледового плавания (СЛП) и их влияние на конструктивную безопасность судна остаются недостаточно изучены. Предлагаемые методики носят качественный характер и сложны для применения на практике. Изучение предельных возможностей бортовых перекрытий при действии сосредоточенной ледовой нагрузки проводилось авторами на адекватных математических моделях предельной поверхности в виде макроотклика бифуркационных аналогий.

Repair of cracks in the ship plates is the most responsible and complex operation The task of obtaining the specified dimensions of the melt on the reverse side of the welded metal is sharply complicated in cases where access to the reverse side of the seam is difficult or even impossible, the implementation of double-sided welds on the outer skin of the hull of the vessel, in most cases for access to damaged areas, leads to an increase in the number of related works on the dismantling (installation) of equipment and affects the normative terms of repair of vessels, including when ships are parked in the dock. This paper presents the results of the study of the effectiveness of the technology of repair of cracks in the ship plates, by orienting the welding bath along the damage plane, due to the comb cutting of the damaged area with different geometry of the edges. The results of analytical research and factor experiments assessment of the strength of welded joints with different geometry of comb cutting, with one-sided welding, using different welding materials and varying welding modes. The results of metallographic research (on macro-grinds) of the obtained welded joints are given. Technologically effective parameters of comb cutting of cracks in ship plates are proposed for practical application in ship repair.
Comparative analysis of parameters of vessels interaction with the ground

Published: March 2022

Взаимодействия судов с грунтом происходят сравнительно часто. Сценарии взаимодействия судов с грунтом бывают как аварийные, так и эксплуатационные. Аварии с посадкой судов на грунт чаще связаны с навигационными ошибками. Следствиями таких аварий являются большие материальные потери, экологические катастрофы и даже гибель судов и людей. Эксплуатационные сценарии связаны с плановыми посадками судов на грунт для проведения грузовых операций на необорудованный берег, отвечающими определённым условиям безопасности. Такие грузовые операции имеют особую важность и актуальны для обширного побережья северных и дальневосточных морей России, где строительство причальных сооружений экономически не оправдано. При любом сценарии оценка параметров взаимодействия судов и грунта важна и актуальна. В работе выполнены сравнения результатов оценки параметров взаимодействия судов с грунтом, полученных как в экспериментах, так и по разным методикам. Основное внимание уделено сравнению методики авторов. Результаты сравнений показали, что методика авторов обеспечивает адекватную оценку основных параметров взаимодействия.

The interaction of vessels with the ground occurs also relatively. Scenarios of vessels interaction with the ground are accidental and operational. Vessel grounding are more often associated with navigation errors. The consequences of such accidents are large material losses, environmental disasters and the loss of vessels and human. Operational scenarios related to planned vessel grounding for cargo operations on an unequipped shore that meets certain safety conditions. Such cargo operations are especially important and relevant for the extensive coastline of the northern and Far Eastern seas of Russia where the construction of berthing facilities is not economically justified. In any scenario, the assessment of the parameters of vessel interaction with the ground is important and relevant. The paper compared the results of assessing the parameters of vessel interaction with the ground, which obtained in experiments and using different methodologies. The main attention is given to the comparison of the authors' methodology. The results of the comparisons showed that the authors' methodology provides an adequate assessment of the main interaction parameters.

Тенденции развития современных судовых дизелей связаны прежде всего с увеличением их удельной мощности, улучшением параметров экономичности и экологических характеристик. Это обуславливает появление ряда проблем, важнейшей из которых является проблема тепловой напряжённости деталей, образующих камеру сгорания. Высокий уровень тепловых нагрузок указанных деталей судовых дизелей является одной из основных причин снижения их эксплуатационной надежности. Ошибки в расчетных оценках теплового и напряженно-деформированного состояния деталей камеры сгорания на стадии проектирования в настоящий период достигают 30 – 80 %. Это вызывает необходимость совершенствование математических моделей, описывающих процессы теплообмена в камере сгорания судовых дизелей. Целью данной статьи является представление и обсуждение результатов исследований, проведенных авторами, по оптическим характеристикам частиц сажи и радиационному теплообмену в камере сгорания судового дизеля типа 6 ЧН 24/36. Экспериментально доказано, что частицы сажи, образующиеся в камере сгорания судового дизеля, могут быть отнесены к малым с оптической точки зрения. Значения средних за рабочий цикл локальных результирующих потоков излучения для поверхностей крышки цилиндра, поршня и втулки, представленные в статье, позволяют еще на стадии проектирования определить в них величину переменных температурных напряжений. Это очень важно для оценки надежности работы деталей камеры сгорания в эксплуатации.

В статье рассматривается вопрос о возможности и целесообразности перевода пассажирских судов, осуществляющие перевозки экскурсионно-прогулочными маршрутами по внутренним водным путям Санкт-Петербурга и в акватории Финского залива, на сжиженный природный газ. Отмечается, что несмотря на опыт создания пассажирского судна на СПГ «Чайка-СПГ», существуют препятствия к реализации проекта, основным из которым является отсутствие инфраструктуры по бункеровке судов такого класса. Кроме того, имеющаяся нормативная база по газотопливному судоходству и СПГ-бункеровке недостаточна для практического применения и требует доработки. Приводится сравнительный расчет экономической эффективности эксплуатации судов на СПГ. Высокая стоимость судов, связанная с высокой долей импортного судового комплектующего оборудования, а также с удорожанием проектов в связи с единичностью и индивидуальностью исполнения заказа, оказывает отрицательное влияние на экономическую эффективность проекта. Для реализация таких проектов необходимо государственное вмешательство − льготное кредитование, компенсация части стоимости судна, компенсация части накладных расходов – необходимые меры для привлечения судовладельцев.

The article considers the question of the possibility and expediency of transferring passenger ships carrying out sightseeing and pleasure routes along the inland waterways of St. Petersburg and in the waters of the Gulf of Finland to liquefied natural gas. It is noted that despite the experience of creating a passenger vessel on LNG "Chaika-LNG", there are obstacles to the implementation of the project, the main of which is the lack of infrastructure for bunkering vessels of this class. In addition, the existing regulatory framework for gas-fuel shipping and LNG bunkering is insufficient for practical application and needs to be finalized. A comparative calculation of the economic efficiency of the operation of LNG vessels is given. The high cost of ships associated with a high proportion of imported ship components, as well as the rise in the cost of projects due to the uniqueness and individuality of the execution of the order, has a negative impact on the economic efficiency of the project. For the implementation of such projects, government intervention is necessary − preferential lending, compensation of part of the cost of the vessel, compensation of part of the overhead costs - the necessary measures to attract ship-owners.

Для решения задачи автоматического выбора управленческих воздействий на множестве заданных альтернатив в условиях нестабильной окружающей среды, возникает необходимость в построении многопараметрических эмпирических моделей сложных технологических процессов с четко заданными коэффициентами. Построена аналитическая зависимость показателей эффективности сложных технологических процессов от параметров управления в виде графика или аналитической связи между зависимой и независимыми переменными лингвистической функции, которая построена по экспертным данным, обработанным методом множественного регрессионного анализа. Графики лингвистических функций позволяют визуализировать зависимость показателей эффективности технологического процесса от параметров управления, установить наиболее чувствительные из них. Предложена методика оценки комплексной эффективности и оптимального управления реализацией сложных технологических процессов. На основе принципа гибкого приоритета определен интегральный критерий оценки эффективности текущего состояния технологических процессов, позволяющий свести решение многокритериальной задачи выбора эффективных управляющих воздействий к однокритериальной оптимизационной задаче при наличии как максимизируемых, так и минимизируемых показателей эффективности.

To solve the problem of automatic selection of management influences on a set of given alternatives in an unstable environment, it becomes necessary to build multi-parameter empirical models of complex technological processes with clearly specified coefficients. The analytical dependence of the efficiency indicators of complex technological processes on the control parameters in the form of a graph or an analytical relationship between the dependent and independent variables of the linguistic function, which is built on the basis of expert data processed by the method of multiple regression analysis, has been built. Graphs of linguistic functions make it possible to visualize the dependence of technological process efficiency indicators on control parameters, to establish the most sensitive ones. A methodology for assessing the integrated efficiency and optimal management of the implementation of complex technological processes is proposed. On the basis of the principle of flexible priority, an integral criterion for evaluating the effectiveness of the current state of technological processes has been determined, which makes it possible to reduce the solution of the multicriteria problem of choosing effective control actions to a single-criterion optimization problem in the presence of both maximized and minimized performance indicators.

Данная работа является продолжением статьи авторов 2020 года. В статье рассматриваются задачи по определению границ участков концентрации транспортных происшествий в пределах территории Волжского бассейна. Для этого созданы в границах Волжского бассейна три базы данных по транспортным происшествиям: с периодами наблюдений 1980-2008, 2007-2018 и 1980-2018 лет. Для определения границ участков концентрации транспортных происшествий применялся расчет плотности транспортных происшествий на участках, сопоставление полученных данных с усредненными и распределения плотности происшествий. В результате выполненной работы были не только определены границы участков по каждому периоду, но и проанализировано изменение границ участков во времени. В работе также введено понятие смещения участков концентрации и прописана методика его определения. Анализ смещения участков концентрации транспортных происшествий позволил разработать классификацию опасных участков, сделать предложения по учету временного фактора при анализе статистических данных для совершенствования методик анализа риска транспортных происшествий и разработке системы мер реагирования.

This work is a continuation of the article by the authors of 2020, which considers the tasks of determining the boundaries of areas of concentration of traffic accidents within the territory of the Volga basin. For this, three databases on transport accidents have been created within the boundaries of the Volga basin: with observation periods of 1980-2008, 2007-2018 and 1980-2018. To determine the boundaries of the concentration areas of traffic accidents, the calculation of the density of traffic accidents at the sections, comparison of the obtained data with the averaged ones and the distribution of the density of accidents were used. As a result of the work performed, the boundaries of the plots were not only determined for each period, but also the change in the boundaries of the plots in time was analyzed. The work also introduces the concept of displacement of concentration sites and spelled out a method for its determination. The analysis of the displacement of the concentration areas of transport accidents made it possible to develop a classification of hazardous areas, to make proposals for taking into account the time factor in the analysis of statistical data to improve the methods for analyzing the risk of traffic accidents and to develop a system of response measures of statistical data to clarify the methods for analyzing the risk of traffic accidents and develop a response system.

Для выработки приближённого решения в классе задач о поиске оптимального пути судна, могут быть применены методы динамического программирования и дискретной оптимизации на графах. С точки зрения судовождения, такие решения представляют собой стратегию «менеджмента курсов». Реальная стратегия плавания судна по линии заданного пути (ЛЗП) включает в себя также управление скоростью судна. В настоящее время не существует единого подхода к решению этой задачи. В данной статье предлагается рассмотреть модель системы поддержки принятия решений (СППР), которая позволяет выработать решение об изменении текущего режима эксплуатации главной судовой энергетической установки (ГСЭУ), а именно изменить число RPM (оборотов в минуту).В данной статье использован математический аппарат нечётких функций и нечёткой логики при построении модели СППР. В случае выработки решения об изменении RPM, на основании мониторинга текущего состояния судна, возникает ещё одна проблема – при изменении скорости судна оптимальный путь, найденный на этапе планирования перехода не является больше таковым, в связи с этим необходимо выработать решение о целесообразности его перестроения. Методология решения этих проблем представлена в данной работе.

There is no universal solvation of this task. In this article described Decision Support System (DSS), which can generate the decision to change the mode exploitation of Main Engine, for instance: change its RPM. The mathematical model of Fuzzy Functions and Fuzzy Sets had been used to create such DSS ME. In case of determination the decision of RPM alteration the previous Path should not be used as Targeted due to prevailing condition, thus it is problem to be solved also. Thus, The Optimization of the Path should be re-calculated. The methodology of abovementioned problems is stated in this article.

Harmonic Assessment in Jordanian Low-Voltage Electrical Power Grid
Authors: Almaita Eyad
Published: March 2022

With the proliferation of nonlinear loads in the power system, harmonic pollution becomes a serious problem that affects the power quality in both transmission and distribution systems. Understanding and quantifying the harmonics level in electrical power grid are crucial before proposing any successful method for mitigating harmonics problems in the grid. In this paper, the harmonics level in Jordan Low-Voltage Electrical Power Grid (JLVEPG) is investigated. The loads are divided into five categories: : (i) industrial loads, (ii) commercial loads, (iii) hospital loads, (iv) residential loads, and (v) office loads. Assuming each category will inject similar harmonics in the grid, this will make the harmonic assessment in the power system is easier and help proposing harmonic mitigation solutions. A field measurement for the major electrical units (Voltages, currents, and power) in JLVEPG is carried out for different locations in multiple cities. These measurements are followed by data analysis techniques in order to identify the total harmonic distortion (THD) and the most dominant harmonic in each load category.

De civis europaeus sum. Una propuesta teórica para la construcción de una identidad constitucional europea
Authors: García Ortiz Adrián
Published: March 2022

Asumida como premisa la necesidad de una identidad europea que sustente y legitime democráticamente el nivel supranacional de ejercicio de poder en que ha devenido la Unión Europea, el presente artículo tiene como objetivo el establecimiento de una propuesta teórica para el análisis de la categoría de identidad en el ámbito del Derecho constitucional y su traslación al espacio de la Unión Europea. Para ello, el estudio se divide en dos partes: por un lado, la realización de una reconstrucción del concepto de identidad y, en particular, de la identidad colectiva nacional, a partir de la distinción en la misma de una dimensión cultural y política; por otro lado, se estudian las bases identificables en el actual estado de la Unión que permiten determinar los elementos materiales suficientes para la reafirmación de una cultura común europea y la proposición de un proyecto político propio capaz de generar una identidad constitucional europea.

Contextualizing knowledge has served to enhance our understanding of human progress. Several academicians and scholars have worked indigenously towards the ‘Think Locally and Act Globally’ mantra to normative approaches across academic disciplines. Recent academic progress led us to think, reflect and question the need for developing a protocol for culturally sensitive ethical practices in Social Sciences. This paper emerges from the deliberations held in a two-day National Symposium on Ethics in Social Science Research and Publication organized and hosted by the department of Human Development and Childhood Studies, Institute of Home Economics, University of Delhi. The paper explores the need for a discipline specific outline of ethical practices in research and debates the requirement for a protocol for the same. Drawing from various examples and dilemmas shared by social science experts, an array of missing links, gaps and epistemic variations are presented through the paper
FOOD AND FEMININE CONNECTION IN THE BENGALI MOVIE, SWADE AHLADE- AN INTERPLAY OF OPPRESSION AND FREEDOM
Authors: Basu Sompurba
Published: March 2022

Womanhood and its connection with food is an area which has been explored in Indian cinema many a times. While a lot has been conveyed through close-ups and silent gaze of the female protagonists about the fettered, homely environment, the claustrophobic kitchen bound lives, being the sex item in a patriarchal society, a different perspective about the liberation through food and culinary skills has also been proposed. This research paper is an attempt to study the portrayal of the feminine gender with its relation to food in the Bengali movie, Swade Ahlade and show the other side of the coin, where it becomes a form of freedom with all its art and creativity. It also gives the women, economic emancipation, thereby providing them with a new identity to vouch upon. The kitchen, which is initially looked upon as a menace to the female identity, becomes the source of upliftment, with monetary benefits. Food, the basic provider of life, is symbolic of womanhood, with its power to give birth and nourishment. The way a child is reared with love, affection and care, is similar to a recipe, with its various ingredients. It is unfortunate that the nurturer herself is exempted from the desired respect, due to its consideration of unpaid labour. The movie, Swade Ahlade explores the possibility of converting this gendered thought process into a powerful weapon of freedom. The paper is based on the theoretical framework of Nivedita Menon’s Seeing Like A Feminist and Laura Mulvey’s ‘male gaze’, as explored in her seminal work, “Visual Pleasure and Narrative Cinema”.

COVID-19 pandemic has affected all the industries of India in general and the Indian textiles & handloom and handicraft industry in particular to a great extent. In the same measure, the silk industry is no exception and the pandemic intensely affected the demand and supply of Assam silk products too. All the industries have devised different strategies to counter the effect and revive the industries. Similarly, the Assam silk industry has also adopted some revival strategies during this pandemic. In this backdrop, this study is an attempt to explore the strategies adopted by Assam silk shopkeepers to revive the silk industry. It further analyses various government assistances to sustain the silk industry. Primary data were collected from 60 number of Assam silk shopkeepers of Sualkuchi area by in depth interview through unstructured schedule. The findings indicate that the Assam silk shopkeepers failed to devise effective strategies but rather relied more on Government assistance in large scale for revival during the pandemic

Simple chronic instability of the elbow joint is one of the urgent problems in modern traumatology due to the fact that the standard tactics of managing patients with traumatic injuries of the elbow joint due to dislocation, which amounts to its elimination, immobilization of the upper limb and subsequent development of movements in the joint, most often does not take into account damage to specific soft tissue structures. With untimely treatment for qualified help, with late or unsuccessful attempts to eliminate dislocation of the bones of the forearm, less often with chronic traumatization of the ligamentous apparatus of the elbow joint during some types of occupation, one of the most unpleasant complications may form, namely, chronic instability. This article discusses the main types of chronic instability of the elbow joint, analyzes approaches to the management of patients with simple chronic instability. Despite the not very high occurrence of this pathology, the effectiveness of modern surgical treatment options aimed at reconstruction of the ligamentous apparatus of the elbow joint, the percentage of unsatisfactory results of treatment of simple chronic recurrent and persistent instability of the elbow joint remains high.

Purpose. Analysis of surgical aspects of the experience of 13 years of percutaneous endoscopic microgastrostomy for enteral therapeutic provision of patients with parkinsonism.

Methods. The 4-year follow-up group (2012-2021) included 20 patients aged 55 to 72 years with severe Parkinson's disease, mostly men. From 2008 to 2012, patients underwent microgastrostomy installation using a Frezenius kit. Levodopa carbidopa was injected into the jejunum through a micro-drainage gastrostomy.

Results. During the 1st year of gastrostomy functioning, the following complications developed: gastric juice leakage onto the skin with the skin maceration development (2 cases), the hypergranulation development around the gastrostomy (3 cases), the gastrostomy support ring prolapse into subcutaneous fat with an abscess development (2 patients). By the end of the 4th year follow-up, 3 more patients had gastrostomy prolapse into subcutaneous tissue without suppuration. On the micro-drainage part complications were observed in the form of the bezoar formation at the tube end and micro-drainage nodulation in the stomach with the lumen obturation. The author used different methods of prevention and complications treatment in each individual case. To prevent gastric juice leakage and the proliferation of hypergranulations, tube fixation correction and local treatment are necessary; to prevent prolapse of the gastrostomy support ring, it is advisable to use a prolene mesh gasket. A gastrostomy change l with proper care is advisable 1 time in 3-4 years, micro-drainage at least 1 time in 2 years to prevent the bezoar formation on the catheter and its rupture.

Conclusion. Puncture microgastrostomy performed under endoscopic control can be effectively used for a long time to inject nutritional mixtures and medicines into the gastrointestinal tract.

Relevance. To evaluate the effectiveness of X-ray endovascular embolization of the portal vein branch in terms of preparation for extensive liver resections.  Materials and methods. A retrospective analysis of 74 right-sided hemihepatectomies performed in one stage (classical, n = 54) or in two stages (X-ray endovascular embolization of the right portal vein followed by liver resection was performed, n = 20).

Results. X-ray endovascular embolization of the right portal vein was accompanied by a significant increase in the planned liver remainder by an average of 37.3 %. This made it possible to reduce the volume of intraoperative blood loss, the incidence of postresection hepatic failure from 43.1 to 15.9 %, and postoperative mortality from 9.3 to 5.0 %.

Conclusions. Preoperative X-ray endovascular embolization of the right portal vein leads to vicarious enlargement of the left lobe of the liver. This makes it possible to reliably reduce the incidence of post-resection hepatic failure after right-sided hemihepatectomy and, accordingly, reduce the frequency of deaths.

Intra- and postoperative complications in the surgical treatment of nodular and multinodular euthyroid goiter make up from 0.3 to 8.0% of the number of operated patients. Depending on the clinical picture, data of morphological, radiation, laboratory studies, various types of surgical interventions are used.  

The objective was to analyze the causes and search for ways to prevent and treat the ntraoperative and postoperative complications in the surgical treatment of patients with nodular and multinodular euthyroid goiter.  

Methods and materials. There was conducted the analysis of the techniques and results of surgical treatment of 303 patients with nodular euthyroid goiter and 377 patients with multinodular euthyroid goiter, divided into two groups: the main group (352 patients) and comparison (328 patients).  

Results. The immediate and long-term results of the treatment of patients were studied with the detailing of specific and nonspecific complications by groups. Methods for optimizing diagnostic and treatment technologies have been developed, immediate and long-term results of treatment have been evaluated.  

Conclusion. The use of improved technologies has reduced the number of intraoperative and postoperative complications and improved treatment results.

Introduction. Tactics of treatment of fractures of the metacarpal bones are sufficiently covered in domestic and foreign literature, however, the search for modern methods of the most effective fixation of fractures of the hand bones is still ongoing. The fixator should ensure the stability of bone fragments, have sufficient strength and undergo biodegradation after fusion, eliminate the need for repeated surgery. Purpose of the study: to evaluate results of fixation of 2-5 metacarpal fractures using bioabsorbable implants.

Materials and methods: there was a retrospective study of 40 patients who had displaced closed fractures of 2-5 metacarpal bones. We performed surgical treatment: open reduction of the metacarpal fracture and internal fixation with bioabsorbable implants (Bioretec Activa Pin). Patients were examined before, 3 and 12 months after surgery.

Results: All patients had union of metacarpal fracture 3 months after surgery. The function of the hand has improved, when evaluated on the DASH scale from 62 to 9.2 (p≤0.05). The pain level (VAS) was significantly decreased from 72 to 13.5 (p≤0.05). All parameters were comparable by 12 months after surgery.

Conclusions: bioabsorbable implants are reliable way for internal fixation of fractures of 2-5 metacarpal bones with displaced fragments. Method is no need to remove the fixator.

The Nancy Grace Roman Space Telescope will conduct a High Latitude Spectroscopic Survey (HLSS) over a large volume at high redshift, using the near-IR grism (1.0–1.93 μm, R = 435–865) and the 0.28 deg2 wide-field camera. We present a reference HLSS that maps 2000 deg2 and achieves an emission-line flux limit of 10−16 erg s−1 cm−2 at 6.5σ, requiring ∼0.6 yr of observing time. We summarize the flowdown of the Roman science objectives to the science and technical requirements of the HLSS. We construct a mock redshift survey over the full HLSS volume by applying a semianalytic galaxy formation model to a cosmological N-body simulation and use this mock survey to create pixel-level simulations of 4 deg2 of HLSS grism spectroscopy. We find that the reference HLSS would measure ∼10 million Hα galaxy redshifts that densely map large-scale structure at z = 1–2 and 2 million [O iii] galaxy redshifts that sparsely map structures at z = 2–3. We forecast the performance of this survey for measurements of the cosmic expansion history with baryon acoustic oscillations and the growth of large-scale structure with redshift-space distortions. We also study possible deviations from the reference design and find that a deep HLSS at f
line > 7 × 10−17 erg s−1 cm−2 over 4000 deg2 (requiring ∼1.5 yr of observing time) provides the most compelling stand-alone constraints on dark energy from Roman alone. This provides a useful reference for future optimizations. The reference survey, simulated data sets, and forecasts presented here will inform community decisions on the final scope and design of the Roman HLSS.
