A high-efficiency and wide-load current range LDO with dynamic loop gain control technique

The design proposes a low-dropout regulator incorporating dynamic loop gain control to accommodate a wide load current range. It introduces a multi-phase error detection mechanism, a tri-state damping selector, and a dynamic integration shift register. These elements predict load variations and dynamically increase loop gain when the load variation is significant, all without increasing the input clock. This approach achieves a fast response and low power consumption simultaneously. The chip was implemented in 0.18 μm CMOS, with an input operating voltage of 1.2 V and an output voltage of 1 V. The measured results revealed that it could provide output currents from 0.5 to 150 mA, indicating that it had a 300 times wider current range. The maximum current efficiency was 99.93%, and the core area was 0.198 mm2.

Proposals to create an end-to-end budgets system, consisting of functional (operational) budgets (wages, material costs and consumption of other resources, depreciation, other costs, repayment of loans, taxes), which will cover the entire base of enterprise financial calculations developed. It is recommended to create dynamic registers that serve for operational accounting and, accordingly, current management of financial resources

Modeling and physical attack resistant authentication protocol with double PUFs

As new lightweight hardware security primitive, the physical unclonable function (PUF) is used in various hardware-based secure applications like keys generation and device authentication. But PUFs are vulnerable to modeling attacks using machine learning (ML) technology. To solve the problem, a dynamically configurable obfuscation unit for PUF using a dynamic linear feedback shift register (DLFSR) is proposed. The structure of this obfuscation unit can change with the clock cycle running, making the PUF difficult to model. Using the obfuscation unit, a dual-PUF-based mutual device authentication protocol for low-cost IoT systems is proposed. New technologies like dual-stage and device-to-server authentication are used to limit the amount of data that an attacker can obtain. A random pattern-based mechanism is introduced to the protocol to enhance the robustness against physical attacks. A mathematical model of the proposed unit is presented and analyzed. Experimental results on FPGA show that the design is simpler, more reliable, and lightweight. It can effectively resist ML-based attacks and physical attacks.

Dynamic catalog of traditional music: online resources of ukrainian folklore and ethnography (access for 2022)

In recent decades, the global Internet network has become a repository of academic knowledge from all areas of science. Domestic ethnographic disciplines (ethno-sciences) are no exception: publications of modern studies appear annually; the fund of digitized older editions made available for free access is replenished; archival recordings and special creative products inspired by traditional music are published.
 After the military attack on Ukraine, there has been an increase in the interest of Ukrainians and residents of democratic countries in the world in Ukrainian culture and music, in particular, in traditional music. This new demand raises the question of the availability of high-quality Internet information in this field not only for specialists, but also for a wide audience.
 By the end of 2022, a rapid increase in the number of high-quality electronic resources of various formats related to the study and popularization of Ukrainian folklore and ethnography has become noticeable.
 The mentioned factors pushed the author to the idea of compiling a catalog of folklore resources in the form of a dynamic electronic register, which will be constantly updated and supplemented.
 This list, with the working title "Dynamic catalog of traditional music", includes both the most authoritative electronic resources in the field of ethno-disciplines, which are progressive in terms of content, as well as little-known ("underground") sources, which, in the opinion of the author, also deserve the attention of academic specialists and teachers.
 This basic list of Internet links will primarily be needed by music school teachers (in the course of studying folk music of Ukrainians), students - ethnologists, ethnomusicologists, folklorists, historians, linguists - and their teachers, as well as those who practice, research and popularize traditional music . It will also be useful for those who want to discover traditional culture and implement ancient customs in their private or public life.

Partial Pseudo-Random Hashing for Transactional Memory Read/Write Data Processing and Validation

Development of a bypass parallel processing block is one of the emerging and interesting research areas in memory read/write application domain. Many Random Number Generation (RNG) techniques have been introduced for processing the data in storage memory. But the limitations include reduced efficiency, increased computational complexity, high area consumption and higher cost. This paper presents a novel dynamic memory register with optimal XOR design based on partial pseudo-random hashing to process transactional memory read/write data. Transfer characteristics of the current are analysed based on the pseudo differential pair for proficient memory utilization. A memory window is then created and adjusted for obtaining an optimal power flow with lesser data loss. The performance of the proposed design is evaluated using different performance measures. The power consumed for processing the data using the proposed design is reduced to nearly 25% when compared to other proposed designs along with reduced component usage. Delay is reduced to 2.31ns and a 15% improvement in frequency and nearly 4% increase in throughput is seen when compared to existing methods.

The association between access to emergency respite and hospital admission: A longitudinal, cohort case register study

Accessible Summary Local areas have a register of people with a learning disability who are at risk of going to hospital. This register helps learning disability services to know when a person needs extra support, such as emergency respite, to stop them going to hospital. This study aimed to see what factors were related to whether people with a learning disability went to hospital for their mental health problems. Service users on the registers in five areas from 2019 were included in this study. What support each person had while they were at risk was looked at. 51 cases were reviewed. We found a relationship between emergency respite and needing to go to hospital. This suggests that emergency respite is related to reducing the chances of someone going to hospital for their mental health problems. The chance to use emergency respite and support may help stop people with a learning disability needing to go to hospital for their mental health. This study can help services to provide the right support for people. AbstractBackgroundReducing hospital admissions for people with a learning disability is a key objective of national guidelines. However, there are currently little available data which indicate factors which might reduce the risk of hospital admission. Using a cohort of people at risk of hospital admission, this research sought to explore the association between access to emergency respite and hospital admission.MethodsThis study accessed data from 76 clients who were based within Pennine Care NHS Foundation Trust, who were on the Dynamic Risk Register due to assessed risk of possible hospital admission. After the employment of inclusion criteria, data from 51 clients were used in the analysis. The study accessed data from clinical records and any professionals meeting minutes (e.g., care and treatment review) from a 12‐month period; information was collected pertaining to participants’ diagnoses and the treatments and interventions that they had received.FindingsWhilst controlling for other interventions, a significant association between hospital admission and access to emergency respite was found, with emergency respite significantly reducing the odds of hospital admission (OR 0.05, CI 0 to 0.36, p = .001). Not having access to emergency respite increased the odds of hospital admission by 20.56 times.ConclusionIn the study catchment area, emergency respite appears to be significantly associated with a reduction in hospital admission, independent of other interventions offered. Further research is necessary to explore if this study's findings are replicable in other areas. This study has implications for the development of emergency respite services in local areas.

Triple negative breast cancer in Bulgaria: epidemiological data and treatment patterns based on real world evidence and patient registries

Breast cancer is the most common oncologic disease among women worldwide. Survival rates vary significantly and depend on early diagnosis practice and access to treatment. Triple negative breast cancer (TNBC) accounts for 12–15% of all breast cancers. We performed a one-year real-life retrospective study on the patho-histological status and treatment of a representative cohort of patients with TNBC in Bulgaria. We collected anonymised data for TNBC patients from the electronic artificial intelligence platform Sqilline - Danny Platform. Demographic characteristics, data on biomarkers, TNM (Tumor, Nodule, Metastasis) stage, therapeutic regime, line and changes in treatment were chronologically analysed for all patients. The results were processed through descriptive statistics. For the observed period, Jan 2019–Dec 2019, 6880 breast cancer patients from eight major oncology hospitals were included in the database. The average age of the women was 60 y; 234 (3.4%) of them were diagnosed with TNBC; 10% had unknown TNM stage. The majority of the patients were assigned to chemotherapy (84%) of which 35% were on adjuvant. Most changes in the therapy were observed in the neo-adjuvant group).The results from this study provide evidence that the treatment patterns of TNBC, and changes in therapy are in compliance with international guidelines. We identified less patients with TNBC than the frequencies reported in international epidemiological studies. This might be attributed to lack of funding of necessary tests or insufficient data in patients record. The study confirms that dynamic patient registers are important for performing a real-world studies of treatment patterns.

Shuttling-based trapped-ion quantum information processing

Moving trapped-ion qubits in a microstructured array of radiofrequency traps offers a route toward realizing scalable quantum processing nodes. Establishing such nodes, providing sufficient functionality to represent a building block for emerging quantum technologies, e.g., a quantum computer or quantum repeater, remains a formidable technological challenge. In this review, the authors present a holistic view on such an architecture, including the relevant components, their characterization, and their impact on the overall system performance. The authors present a hardware architecture based on a uniform linear segmented multilayer trap, controlled by a custom-made fast multichannel arbitrary waveform generator. The latter allows for conducting a set of different ion shuttling operations at sufficient speed and quality. The authors describe the relevant parameters and performance specifications for microstructured ion traps, waveform generators, and additional circuitry, along with suitable measurement schemes to verify the system performance. Furthermore, a set of different basic shuttling operations for a dynamic qubit register reconfiguration is described and characterized in detail.

Improving Error Correction Stage and Expanding the Final Key using Dynamic Linear-feedback Shift Register in Sarg04 Protocol

The mechanism of quantum mechanics is considered as the principal method of quantum key distribution for transmitting a cryptographic key between users in unconditionally secure communication. In this paper, simulation and enhancement of the performance of SARG04 protocol have been done in terms of error correction stage using multiparity rather than single parity. In addition, the suitable length of subblock was selected depending on the values of quantum bit error rate and round number. Dynamic linear-feedback shift register circuits have been used to extend the final key. These circuits are dynamically generated by the final key. A unique linear circuit is created for each generated key.

Conception de tâches MERLO: un dispositif dans la formation continue pour l’enseignement de la géométrie

In this exploratory empirical study, we use a relatively new teacher education apparatus that consists of developing MERLO tasks, which provides fertile ground for teachers to engage in secondary-level mathematical concept study. Within the domain of geometry, we illustrate how this apparatus can help to clarify certain important concepts, specifically in relation to the coordination of visual and linguistic registers, which is at the heart of geometric reasoning. We also discuss the possibility of using this approach as a means of exploring another mathematical register: the dynamic register.

Software-Directed Techniques for Improved GPU Register File Utilization

Throughput architectures such as GPUs require substantial hardware resources to hold the state of a massive number of simultaneously executing threads. While GPU register files are already enormous, reaching capacities of 256KB per streaming multiprocessor (SM), we find that nearly half of real-world applications we examined are register-bound and would benefit from a larger register file to enable more concurrent threads. This article seeks to increase the thread occupancy and improve performance of these register-bound applications by making more efficient use of the existing register file capacity. Our first technique eagerly deallocates register resources during execution. We show that releasing register resources based on value liveness as proposed in prior states of the art leads to unreliable performance and undue design complexity. To address these deficiencies, our article presents a novel compiler-driven approach that identifies and exploits last use of a register name (instead of the value contained within) to eagerly release register resources. Furthermore, while previous works have leveraged “scalar” and “narrow” operand properties of a program for various optimizations, their impact on thread occupancy has been relatively unexplored. Our article evaluates the effectiveness of these techniques in improving thread occupancy and demonstrates that while any one approach may fail to free very many registers, together they synergistically free enough registers to launch additional parallel work. An in-depth evaluation on a large suite of applications shows that just our early register technique outperforms previous work on dynamic register allocation, and together these approaches, on average, provide 12% performance speedup (23% higher thread occupancy) on register bound applications not already saturating other GPU resources.

CRAT: Enabling Coordinated Register Allocation and Thread-Level Parallelism Optimization for GPUs

The key to the high performance on GPUs lies in the massive threading to enable thread switching and hide long latencies. GPUs are equipped with a large register file to enable fast context switch. However, thread throttling techniques that are designed to mitigate cache contention, lead to under-utilization of registers. Register allocation is a significant factor for performance as it not just determines the single-thread performance, but indirectly affects the TLP. In this paper, we propose Coordinated Register Allocation and Thread-level parallelism ( CRAT ) to explore the optimization space of register allocation and TLP management on GPUs. CRAT employs both compile-time(CRAT-static) and run-time techniques(CRAT-dyn) to exhaust the design space. CRAT-static works statically to explore TLP and register allocation trade-off and CRAT-dyn exploits dynamic register allocation for further improvement. Experiments indicate that CRAT-static achieves an average 1.25X speedup over existing TLP management technique. On four register-limited applications, CRAT-dyn further improves the performance speedup of CRAT-static from 1.51X to 1.70X.

The Key to the Cardiovascular Diseases Situation Improvement in Conditions of North-West Region of Russia

The purpose of research - studying patients’ adherence of arterial hypertension and ischemic illness of heart to treatment in conditions of Northwest region of Russia. In the period from 2012 to 2013 by analogy with a “Regular Treatment and Prevention as the Key to Improving CVD Situation in Russia - RELIEF” large-scale study on assessing patients adherence to doctor's recommendations was conducted. The study analyzed the factors that have more or less significant impact on the quality of treatment and the adherence to treatment of hypertension and CHD. Assessment of adherence to treatment of patients is given according to data received from 28 district doctors/general practitioners who have included 78 patients with proven hypertension/CHD. Analysis of the received data is performed with the help of Program Statistica 10, Stat Soft. There is insufficient awareness among respondents about risk factors and disease outcome. A radical change has been proposed for principles of preventive care for patients, taking into account all the prevention elements for hypertension/CHD in cardiac treatment centers or preventive medicine and rehabilitation centers, with creating dynamic active register of patients with hypertension/CHD and related complications.

An Efficient WCET-Aware Instruction Scheduling and Register Allocation Approach for Clustered VLIW Processors

In real-time embedded system design, one major goal is to construct a feasible schedule. Whether a feasible schedule exists depends on the Worst-Case Execution Time (WCET) of each task. Consequently, it is important to minimize the WCET of each task. We investigate the problem of instruction scheduling and register allocation for a program executed on a clustered Very Long Instruction Word (VLIW) processor such that the WCET of the program is minimized, and propose a novel, unified instruction scheduling and register allocation heuristic approach. Our heuristic approach is underpinned by a set of novel techniques, including spanning graph-based WCET-aware live range splitting, WCET-aware dynamic register pressure control, WCET-aware basic block prioritization for performing integrated instruction scheduling and register allocation, and WCET-aware spill code handling. We have implemented our approach in Trimaran 4.0, and compared it with the state-of-the-art approach by using a set of 20 benchmarks. The experimental results show that our approach achieves the maximum WCET improvement of 29.61% and the average WCET improvement of 10.23%, respectively.

Probabilistic linkage of national immunisation and state-based health records for a cohort of 1.9 million births to evaluate Australia's childhood immunisation program.

IntroductionSeveral countries have developed national immunisation registers, but only the Nordic countries have linked their registers to other health data in order to comprehensively evaluate the `real world' effectiveness of vaccines. Nordic countries can link datasets deterministically using the national person identifier, but most countries, including Australia, don't have such an identifier to enable this type of linkage.ObjectivesTo describe the process for assembling a linked study cohort that will enable the conduct of population-based studies related to immunisation and immunisation policy.MethodsNational death and immunisation databases along with state health data (notifications of vaccine preventable diseases, perinatal data, hospital admissions and emergency department presentations) up until December 2013 were probabilistically linked (using demographic details) for children born between 1996 and 2012 in two states: Western Australia and New South Wales (42% of Australia's population, combined).ResultsAfter exclusions there were 1.95 million children in the study cohort (live born children with both a birth and perinatal record which represents 97.5% of all live births in the state perinatal data collections - our source population) and 18.0 million person years of follow up (mean: 9.2 years per child). The characteristics of children in the cohort were generally similar to those only included in state perinatal databases and outcome measures were in keeping with expected figures from unlinked data sources. However, the lack of a dynamic national population register meant immigrants could not be included.ConclusionsWe have been able to develop a similarly comprehensive system to the Nordic countries based on probabilistic linkage methods. Our experience should provide encouragement to other countries with national immunisation registers looking to establish similar systems

Total Safety Management: What Are the Main Areas of Concern in the Integration of Best Available Methods and Tools

“BP released findings from its own internal investigation of the oil spill in the Gulf of Mexico, revealed inefficient Organization interfaces among BP management, the rig crew and well site leader. Also according to the investigation, one important contributor to the accident was inadequate guidelines for critical tests and operations”. (Pires and Mosleh 2011) Over the recent past, the accumulation of major mishaps, crises and accidents have made it clear that organisations must still improve their capabilities to address safety “not as a stand-alone activity that is separate from the main activities and processes of the organization” but as an integrated part of total performance management. The requirements for safety management in existing and upcoming standards and regulations, as for example the ISO 31000 and or the Seveso II directive, call for a proactive strategic approach, anticipating risks and demonstrating a capacity to keep safety at the centre of changes driven by commercial competition, and ensuring that safety evidence itself becomes an effective driver of change. However there is often a gap between the state principles and an actual roadmap to their implementation. Furthermore organisations, especially the one dealing with safety critical operations, find it difficult to integrate their different functional units in a common programme of operations management or change; there is no clear consensus about what it means to be ‘proactive’; there is no integrated framework for analysing or managing all the human related functions in an operational system. Innovation may rely on assembling the best practices, tools and methods already available for functional analysis, risk assessment, interactive emergency scenarios analysis, performance monitoring, design review, training and knowledge management, in an integrated framework able to address safety management in the main aspects of a product or process lifecycle the cornerstone of which is the building of a common operational picture to support the capacity to perform more participatory and dynamic risk identification and solutions loops in: - Design (new plants, processes /procedures availing new visualization tools) - Ad hoc critical activities (management of change or scheduled overhaul) - Operations management (establishing of dynamic risk registers). This is the scope of a new EU funded research project called TOSCA and the present paper will introduce the current framework being built.

Improved reconfigurable hyper-pipeline soft-core processor on FPGA for SIMD

Reconfiguration is a powerful computational model in which the processors can be changed dynamically during the execution phase of the system. This paper presents dynamic reconfigurable register file allocation in hyper pipelined OR1200 (Open RISC) for single instruction multiple data (SIMD). The OR1200 instantly reconfigures the actual register file to the reconfigurable register file according to the requirement of the application. The unused general purpose registers obtained during the reconfiguration process can be used for hyper pipelining technique which improves overall performance of the single core processor system. Thus releasing the unused register reduces the power consumption and increases the execution speed of OR1200. This proposed reconfigurable technique is implemented using Verilog and it is tested using MediaBench multimedia benchmark dataset which ensures reduced register utilisation of 16.80% for multimedia dataset and power reduction up to 72.7% with reconfigurable modules. The proposed technique is configured in Virtex-6 field programmable gate array (FPGA) and results are analysed with the existing and proposed reconfigured OR1200.
