Holomorphic integer graded vertex superalgebras

In this paper, we study holomorphic [Formula: see text]-graded vertex superalgebras. We prove that all such vertex superalgebras of central charge [Formula: see text] and [Formula: see text] are purely even. For the case of central charge [Formula: see text] we prove that the weight-one Lie superalgebra is either zero, of superdimension [Formula: see text], or else is one of an explicit list of 1332 semisimple Lie superalgebras.

Peranan Hadis Daif Dalam Menentukan Makna Hadis: Tinjauan Ke Atas Huraian Terpilih Daripada Kitab Syarah

Scholars have different opinions on the function of weak hadith in the construction of law. Thus, the question about its usage in determining the meaning of a hadith arises. This is due to the existence of an agreed method that explains a hadith based on relevant hadiths. This study will look at the practice of authoritative sources of commentaries books in understanding every matter that is attributed to the Prophet SAW. It used a qualitative approach with the methodology of content analysis. The findings show that the usage of weak hadith at least plays two roles. First, the weak hadith serves to weight one of many conflicting hadith's meaning along with other Islamic legal text. Secondly, it becomes evidence for a meaning that has probability or iḥtimāl in a hadith that it may convey. There are three conditions that have been set for the hadiths that can be used. First, it cannot be categorized as very weak. Second, the meanings of the hadith are stated by other evidence. Third, the meaning of the hadith does not contradict the hadith that is in a higher status.

Generalized Concatenated Codes over Gaussian and Eisenstein Integers for Code-Based Cryptography

The code-based McEliece and Niederreiter cryptosystems are promising candidates for post-quantum public-key encryption. Recently, q-ary concatenated codes over Gaussian integers were proposed for the McEliece cryptosystem, together with the one-Mannheim error channel, where the error values are limited to the Mannheim weight one. Due to the limited error values, the codes over Gaussian integers achieve a higher error correction capability than maximum distance separable (MDS) codes with bounded minimum distance decoding. This higher error correction capability improves the work factor regarding decoding attacks based on information-set decoding. The codes also enable a low complexity decoding algorithm for decoding beyond the guaranteed error correction capability. In this work, we extend this coding scheme to codes over Eisenstein integers. These codes have advantages for the Niederreiter system. Additionally, we propose an improved code construction based on generalized concatenated codes. These codes extend to the rate region, where the work factor is beneficial compared to MDS codes. Moreover, generalized concatenated codes are more robust against structural attacks than ordinary concatenated codes.

Prevalence and determinants of Transient Congenital Hypothyroidism in children with Eutopic Gland in France: a retrospective cohort study

Context The increase in the incidence of congenital hypothyroidism (CH) reported worldwide may in part be explained by an increase in the transient form of CH. Objectives We aimed to estimate the proportion of transient CH (TCH) in France, and to identify associated neonatal and young child characteristics. Patients and Methods We used probabilistic record linkage to link children with eutopic gland born between 2006 and 2012 recorded in the national French CH registry and the French national health data system (SNDS). Of the 703 children recorded, 484 (68.8%) were linked. We retrospectively examined reimbursement for oral levothyroxine (LT4) between 01/01/2006 and 31/12/2017. Children who had discontinued treatment for six months or more before 31/12/2017 were classified as having TCH. We used a Cox model to examine the factors associated with TCH. Results Among the main study sample (n=471), 53.5% were female, 14.2% were preterm, and 13.8% had low birth weight. One-quarter (n=111, 24.3%) had mild CH (thyroid-stimulating hormone (TSH)<50mU/L (serum) at diagnosis and a median LT4 dose at treatment initiation of 30 μg/day. One third (n=155, 32.9%) had TCH. Premature birth (adjusted Hazard Ratio=2.1 [1.0-4.2]), a TSH<50 mU/L at CH screening (7.4 [3.2-17.1]), LT4 dose received at 12 months of age (0.98 [0.97-0.99, p=0.003]), congenital cardiac malformations (6.6 [1.5-29.0]), and year of birth (1.2 [1.1-1.4]) were all associated with TCH. Conclusions One third of the children had TCH and it was associated with several characteristics at birth and post-partum. These data are useful for CH medical management and epidemiological surveillance.

Burst pressure design of the cargo tank used in a novel large subsea freight-glider

This paper presents the burst pressure design of the cargo tank used in the University of Stavanger (UiS) Subsea Freight-Glider (USFG). The USFG is an innovative large underwater cargo glider drone that is 50 m long and has a DWT of 1500 ton. It uses variable-buoyancy propulsion instead of traditional propellers for movement. This is an extremely efficient propulsion method and allows the USFG to achieve an average energy consumption of less than 10 kW. Structural weight is a premium as the USFG is required to be neutrally buoyant in water. Therefore, the design of the cargo tank which is the largest component in the USFG needs to be optimal for minimal structural weight. One approach used in design optimisation is to utilise design codes and/or methods that are more precise and therefore allow for lower safety margins. This approach will be investigated in this paper for the burst pressure design of the cargo tank. The different parts of ASME BPVC codes will be compared. The sensitivity of the codes to changes in design parameters is also investigated. Lastly, some comments on the use of reliability methods to further optimise the design are also presented.

Tropical ideals do not realise all Bergman fans

Every tropical ideal in the sense of Maclagan–Rincón has an associated tropical variety, a finite polyhedral complex equipped with positive integral weights on its maximal cells. This leads to the realisability question, ubiquitous in tropical geometry, of which weighted polyhedral complexes arise in this manner. Using work of Las Vergnas on the non-existence of tensor products of matroids, we prove that there is no tropical ideal whose variety is the Bergman fan of the direct sum of the Vámos matroid and the uniform matroid of rank two on three elements and in which all maximal cones have weight one.

The clinical variations and diagnostic challenges of deoxyguanosine kinase deficiency: a descriptive case series

Objectives Deoxyguanosine kinase (DGUOK) deficiency is one of the leading causes of the mitochondrial DNA-depletion syndromes (MDDS) associated with hepatocerebral involvement. Herein, we present four cases of DGUOK deficiency to emphasize the clinical variability of disease and the challenges in the diagnosis of DGUOK deficiency. Case presentation Hepatomegaly, hyperlactatemia, elevated alpha fetoprotein (AFP), alanine, and transaminase levels were detected in all patients, and cholestasis, coagulopathy, and hypotonia were common findings. All patients had a low birth weight, one patient underwent liver transplantation (LT). Clinical and laboratory findings of two patients and one patient suggested neonatal hemochromatosis and type 1 tyrosinemia, respectively. All patients were diagnosed with DGUOK deficiency by performing molecular genetic analysis. Conclusions Mitochondrial DNA-depletion syndromes should be kept in mind in cases in which hypotonicity, lactic acidosis, and neonatal cholestasis are observed. DGUOK deficiency may present in different clinics suggesting neonatal hemochromatosis or tyrosinemia type 1.

100% Intensity of Training on Body Weight Fluctuations Before and After Exercise

This study aimed to prove the effect of 100% exercise intensity on weight gain before and after exercise. This research is motivated by the efforts made by people to achieve the ideal body weight. One of the efforts made is by doing exercises. Proper practice is essential. The quality of the exercise is indicated by the intensity of the exercise performed. The study used experimental methods. The research sample was eight students—measurement of body weight before and after exercise. Perform using 100% intensity circuit training based on maximal tests. Descriptive statistics analyzed data. The results showed that they always experience an average weight loss of 2.8. Based on these results, it can reference that circuit training with 100% load could be used to lose weight. Recommendations, for maximum results, it is necessary to record macro nutritional intake, to know a proper diet for weight loss purposes. Key words: overweight, obesity, BMI, circuit training, maximul load

Longitudinal Gastrectomy for Nonbariatric Indications

Background. Sleeve gastrectomy is the most commonly performed bariatric procedure. Laparoscopic longitudinal gastrectomy (LLG) may be indicated for other indications. Patients and Methods. Two men and two women aged 67, 72, 77, and 80 years underwent LLG for nonbariatric indications with two having normal weight, one being cachectic, and one severely obese. Results. LLG was discussed with patients prior to surgery, but decision for LLG was made during surgery after contemplating other surgical options. A wide sleeve over a 42 French bougie was created with the staple line being oversewn with running 3–0 silk. Indications included a bleeding Dieulafoy lesion that failed endoscopic clipping, fundus gland polyposis found during paraesophageal hernia repair, fundus nodules suspected to be leiomyosarcoma metastases revealing splenosis on final pathology, and significant gastric dilatation associated with organoaxial gastric volvulus. Three patients had an uneventful recovery; the severely obese patient temporarily lost weight but died after two years from a stroke. The last patient developed dysphagia due to an alpha-loop in the sleeve, which was managed by endoscopic stenting. The device subsequently migrated and was laparoscopically removed, with a side-side gastrogastrostomy performed to straighten the alpha-loop. The patient tolerated food better and with overnight PEG tube feeds gained weight but continued heavy smoking. He died after one year from COPD exacerbation. Conclusion. LLG seems to be an appropriate intervention for various gastric pathologies. Training of residents and fellows in the minimally invasive surgical steps of LLG is encouraged.
