The ATLAS Data Acquisition and High-Level Trigger: Concept, Design and Status

The Trigger and Data Acquisition system (TDAQ) of the ATLAS experiment at the CERN Large Hadron Collider is based on a multi-level selection process and a hierarchical acquisition tree. The system, consisting of a combination of custom electronics and commercial products from the computing and telecommunication industry, is required to provide an online selection power of 105 and a total throughput in the range of Terabit/sec. This paper introduces the basic system requirements and concepts, describes the architecture of the system, discusses the basic measurements supporting the validity of the design and reports on the actual status of construction and installation

COVID19-induced xenophobia and anti-Asian racism in the United States

Dr. Ertorer asserts that studying the social effects of the novel coronavirus in diverse, multi-ethnic societies is as important as understanding the health effects of it. In this talk, Dr. Ertorer will address COVID19-induced xenophobia and anti-Asian racism in the United States. The results of her recent study reveals that the COVID-19 pandemic has made people who are perceived as Asian vulnerable to harassment, racism, and discrimination in the COVID era. While inappropriate jokes, slurs, derogatory language are found to be common forms of everyday racism, vandalization of property, denial of housing or a job, and physical attack are the most severe forms of discrimination faced by the participants in the study. Experiences of racism was correlated with mental health. Dr. Ertorer also found that these experiences have a negative effect on victims\u27 sense of belonging to the American society, which is likely to create more divisions and segregation within the community

The effects of hypothyroidism on strength-duration properties of peripheral nerve

PubMedID: 20452625Axonal injury and/or demyelination commonly result in peripheral mononeuropathy, polyneuropathy or entrapment neuropathies in hypothyroidism. In this study, we aimed to measure the strength-duration time constants (SDTC) of motor and sensory fibres in patients with primary hypothyroidism before and after hormone replacement treatment. The motor and sensory SDTC and rheobase of 14 patients with overt hypothyroidism (TSH > 10 mg/ml, free T4 < normal range, with positive thyroid autoantibodies) and 10 age-matched healthy volunteers were measured following stimulation of left ulnar nerve at the wrist. Nerve conduction velocity studies revealed carpal tunnel syndrome in 3 of 14 patients. When the values of patients and control group were compared, motor and sensory rheobase, thresholds using 0.1 ms and 1 ms stimulus for motor and sensory fibres were significantly different (p < 0.05). The values were bigger in patient group reflecting a higher threshold. When the values of patients were compared before and after therapy, motor and sensory rheobase, thresholds using 0.1 ms and 1 ms stimulus for motor and sensory fibres were significantly different (p < 0.05). When the values of 10 of 14 patients who had undergone hormone therapy were compared with the control group, there wasn't any significant difference. Some reports suggest that axonal injury develop in hypothyroidism. Our results suggest that even in the absence of polyneuropathy findings, an increased threshold and in consequence an increased axonal excitability which can improve after hormone therapy may be present in overt hypothyroidism. © 2010 Elsevier B.V.

The Architecture and Administration of the ATLAS Online Computing System

The needs of ATLAS experiment at the upcoming LHC accelerator, CERN, in terms of data transmission rates and processing power require a large cluster of computers (of the order of thousands) administrated and exploited in a coherent and optimal manner. Requirements like stability, robustness and fast recovery in case of failure impose a server-client system architecture with servers distributed in a tree like structure and clients booted from the network. For security reasons, the system should be accessible only through an application gateway and, also to ensure the autonomy of the system, the network services should be provided internally by dedicated machines in synchronization with CERN IT department's central services. The paper describes a small scale implementation of the system architecture that fits the given requirements and constraints. Emphasis will be put on the mechanisms and tools used to net boot the clients via the "Boot With Me" project and to synchronize information within the cluster via the "Nile" tool

Objectives: To describe biochemical and clinical features, and therapeutic outcomes of acromegaly patients in Turkey.Methods: Retrospective multicenter epidemiological study of 547 patients followed in 10 centers of the Turkish Acromegaly registry.Results: A total of 547 acromegaly patients (55% female) with a median age of 41 was included in this study. Majority of patients had a macroadenoma (78%). Transsphenoidal surgery was performed as primary treatment in 92% of the patients (n = 503). Surgical remission rate was 39% (197/503) in all operated patients. Overall disease control was achieved in 70% of patients. Remission group were significantly older than non-remission group (p = .002). Patients with microadenomas had significantly higher remission rates than patients with macroadenomas (p < .001). Patients with microadenomas were significantly older at the time of diagnosis when compared to patients with macroadenomas (p < .001). Preoperative growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels were significantly lower in the remission group (p < .001). Initial IGF-1 and GH levels were significantly higher in macroadenomas compared to microadenomas (p < .001). Medical treatment was administered as a second-line treatment (97%) in almost all patients without remission. Radiotherapy was preferred in 21% of the patients mostly as a third line treatment.Conclusions: This is one of the largest real life studies evaluating the epidemiological characteristics and treatment outcomes of patients with acromegaly who were followed in different centers in Turkey. Transsphenoidal surgery in the treatment of acromegaly still remains the most valid method. Medical treatment options may improve long-term disease outcomes in patients who cannot be controlled with surgical treatment (up to 70%).C1 [Keskin, Caglar; Demir, Ozgur; Sahin, Mustafa; Emral, Rifat; Corapcioglu, Demet] Ankara Univ, Fac Med, Dept Endocrinol & Metab Dis, Ankara, Turkey.[Karci, Alper Cagri; Berker, Dilek] Ankara Numune Training & Res Hosp, Dept Endocrinol & Metab Dis, Ankara, Turkey.[Canturk, Zeynep] Kocaeli Univ, Fac Med, Dept Endocrinol & Metab Dis, Kocaeli, Turkey.[Yaylali, Guzin Fidan; Topsakal, Senay] Pamukkale Univ, Fac Med, Dept Endocrinol & Metab Dis, Denizli, Turkey.[Ersoy, Reyhan] Yildirim Beyazit Univ, Fac Med, Dept Endocrinol & Metab Dis, Ankara, Turkey.[Bayram, Fahri] Erciyes Univ, Fac Med, Dept Endocrinol & Metab Dis, Kayseri, Turkey.[Ertorer, Melek Eda; Bozkirli, Emre; Haydardedeoglu, Filiz] Baskent Univ, Adana Dr Turgut Noyan Training & Res Hosp, Dept Endocrinol & Metab Dis, Adana, Turkey.[Dilekci, Esra Nur Ademoglu] Abant Izzet Baysal Univ, Fac Med, Dept Endocrinol & Metab Dis, Bolu, Turkey.[Ay, Seyid Ahmet] GATA Haydarpasa Training Hosp, Dept Endocrinol & Metab Dis, Istanbul, Turkey.[Cansu, Guven Baris] Eskisehir Yunus Emre Hosp, Dept Endocrinol & Metab Dis, Eskisehir, Turkey
