We give the £rst simple and ef£cient construction of veri£able random functions (VRFs). VRFs, introduced by Micali et al. [MRV99], combine the properties of regular pseudorandom functions (PRFs) [GGM86] (i.e., indistinguishability from a random function) and digital signatures [GMR88] (i.e., one can provide an unforgeable proof that the VRF value is correctly computed). The ef£ciency of our VRF...

The physicochemical parameters of groundwater at Auchi and South-Ibie were investigated to determine underground water quality in this environment. Water sampled locations categorized as Iyekhei (Iyekhei), Poly (Auchi PW), Hostel PH), Double Delight (DDH); are Levis Gas Plant (LGP), Pastoral Centre (PC), Global Castle Sawmill Road (GCHS), Arsenal and, Lagos Street (AHLS). A total number 80 samp...

Redirective, periacetabular osteotomies (PAO) represent a group of surgical procedures for treatment of developmental dysplasia of the hip (DDH) in skeletally mature and immature patients. The ultimate goal of all procedures is to reduce symptoms, improve function and delay or prevent progression of osteoarthritis. During the last two decades, the understanding of the underlying pathomechanisms...

OBJECTIVE Development of the hip joint is complete by 11 weeks of gestation. As triiodothyronine and thyroxine are important regulators of early bone and muscle development, we hypothesized that excessive thyroid hormone in the early fetal period was a congenital risk factor of developmental dysplasia of the hip (DDH). Consequently, it was proposed that elevations of maternal thyroxine in the f...

Members of arachnida, such as spiders and scorpions, commonly produce venom with specialized venom glands, paralyzing their prey with neurotoxins that specifically target ion channels. Two well-studied motifs, the disulfide-directed hairpin (DDH) and the inhibitor cystine knot motif (ICK), are both found in scorpion and spider toxins. As arachnids, ticks inject a neurotoxin-containing cocktail ...

Abstract Aim: To assess the accuracy of clinical coding developmental dysplasia hip (DDH) operations Method 106 children underwent surgery for DDH at our turst from 1997 to 2018. Our department was sent a list patients and operation dates asked tabulate data on what each had been coded as. We compared as with procedure actually performed (as per notes, clinic letters intra-operative fluoroscopy...

Background: The prevalence of neglected developmental dysplasia of the hip (DDH) has been decreasing. Nowadays, the disease is rarely seen in walking age children. The purpose of this study is to assess the results of simultaneous osteotomy of femur and pelvic bones in such children.Method: We performed a retrospective study on 30 children aged 3.8±0.9 (range: 1.5-7) years old, with DDH who und...

BACKGROUND Developmental dysplasia of the hip (DDH) always leads to cartilage degeneration and osteoarthritis of the hip joint. However, the diagnosis of early cartilage degeneration in DDH is still a clinical challenge. This study aims to investigate the dynamic changes of bone and cartilage in the hip of a rat model of DDH and to explore the potential application of microcomputed tomography (...

In an inner-product functional encryption scheme, the plaintexts are vectors and the owner of the secret key can delegate the ability to compute weighted sums of the coefficients of the plaintext of any ciphertext. Recently, many inner-product functional encryption schemes were proposed. However, none of the known schemes are secure against chosen ciphertext attacks (IND-FE-CCA). We present a g...
