For more than fifteen years, researchers have tried to support global optimizations in a usable semantics for concurrent programming language, yet this task has been proven be very difficult because of (1) the infamous "out thin air" problem, and (2) subtle interaction between thread-local optimizations.
For ARMv8 and RISC-V, there are concurrency models in two styles, extensionally equivalent: axiomatic models, expressing the semantics terms of global properties complete executions; operational that compute incrementally. The latter an abstract microarchitectural style: they execute each instruction multiple steps, out-of-order with explicit branch speculation. This similarity to hardware implementations has been important developing establishing confidence, but involves complexity that,...
Safety-critical systems are often designed as real-time distributed systems. Despite the need for strong guarantees of safety and reliability in these systems, applying formal verification methods to at implementation level has faced significant technical challenges. In this paper, we present VeriRT, an end-to-end framework that closes gap between high-level abstract timed specifications low-level implementations Within framework, establish a theoretical foundation constructing operational...
Non-volatile memory (NVM) is a cutting-edge storage technology that promises the performance of DRAM with durability SSD. Recent work has proposed several persistency models for mainstream architectures such as Intel-x86 and Armv8, describing order in which writes are propagated to NVM. However, these have limitations; most notably, they either lack operational or do not support persistent synchronization patterns.
Local data-race-freedom guarantees, ensuring strong semantics for locations accessed by non-racy instructions, provide a fruitful methodology modular reasoning in relaxed memory concurrency. We observe that standard compiler optimizations are inherent conflict with such guarantees general fully-relaxed models. Nevertheless, certain strengthening of the promising model Lee et al. only excludes RMW-store reorderings, we establish multiple useful local data-racefreedom enhance programmability...
We formally show that sequential reasoning is adequate and sufficient for establishing soundness of various compiler optimizations under weakly consistent shared-memory concurrency. Concretely, we introduce a model behavioral refinement in entails contextual the Promising Semantics model, extended with non-atomic accesses non-racy code. This first work to achieve such result full-fledged variety C11-style concurrency features. Central our lifting common data-race-freedom assumption, which...
The objective of this study was to investigate arterial and venous blood gas, electrolytes, biochemical, hematological values in healthy Korean native calves (KNC). 62 KNC within 3 weeks-old were examined. collected from caudal auricular artery the jugular vein. samples analyzed immediately using a portable gas analyzer. pH, pO₂, pCO₂, cHCO₃ − , BE, cSO₂, Na + Ca 2+ Cl anion gap potassium (AgapK), Hct, cHgb, glucose, lactate creatinine determined. normal for variables determined agree with...
We investigate the problem of developing an "in-order" shared-memory concurrency model for languages like C and C++, which executes instructions following their program order, is thus more amenable to reasoning verification compared recent complex proposals with out-of-order execution. demonstrate that it possible fully support non-atomic accesses in in-order a way validates all compiler optimizations are performed single-threaded code (including irrelevant load introduction). The key doing...

Menopause is characterized by rapid decreases in bone mineral density, aerobic fitness, muscle strength, and balance. In the present study, we investigated effects of new sports tennis type exercise on capacity, follicle stimulating hormone (FSH) N-terminal telopeptide (NTX) postmenopausal women. Subjects were consisted 20 women, who had not menstruated for at least 1 yr follicle-stimulating levels > 35 mIU/L, estradiol levels< 40 pg/mL. The subjects randomly divided into two groups: control...
Abstract Background & Aims: Elevated metabolic activity is a defining characteristic of liver cancer. Nevertheless, our understanding the molecular underpinnings high in cancer and its impact on clinical outcomes treatment responses remains limited. We aimed to elucidate features associated with outcomes, particularly overall survival responsiveness sorafenib treatment. Methods: Utilizing cross-species comparisons genomic data, we integrated gene expression profiles from tissues...
Hepatocellular carcinoma (HCC), the most common liver cancer, exhibits a higher incidence in males. Here, we report that mice lacking bile acid regulators, Farnesoid X Receptor (FXR) and Small Heterodimer Partner (SHP), recapitulate sex difference cancer risk. Since few therapeutic options are available, focused on understanding intrinsic protection afforded to female livers. Transcriptomic analysis control FXR SHP double knockout livers identified female-specific changes metabolism,...

OpenADR 수요 반응 프로토콜은 스마트 그리드 환경에서 에너지의 효율적 사용과 지능화 된 수요자원관리 서비스를 제공하기 위하여 개발되었다. HTTP/XML기반의 데이터 트래픽의 오버헤드가 크기 때문에 가정, 빌딩 내의 제약된 환경을 가진 경량 디바이스에서 사용하기 어렵다. 최근 홈 에너지 IoT 환경에서는 가정 초경량 디바이스들을 위한 프로토콜이 요구되고 있다. 본 논문에서는 많이 사용되는 MQTT기반의 2.0b 프로토콜을 제안하고 평가한다. 우선 제안된 구현하고 테스트베드를 통해 HTTP/XML 기반의 프로토콜과의 호환성을 검증한다. 다음은 테스트베드 실험을 구현된 MQTT의 특징인 Broker 게시(Publish)/구독(Subscribe) 기능을 이용하여 Push 실시간 이벤트 전달 메커니즘의 성능을 분석한다. 실험 결과를 OpenADR과의 비교하여 MQTT/JSON기반의 트래픽 측면에서 1/3로 줄어들고 전달측면에서 VEN 개수나 Polling주기와 무관하게...
