In this article, we describe a new command, xtbcfe, that performs the iterative bootstrap-based bias correction for the fixed-effects estimator in dynamic panels proposed by Everaert and Pozzi (2007, Journal of Economic Dynamics and Control 31: 1160–1184). We first simplify the core of their algorithm by using the invariance principle and subsequently extend it to allow for unbalanced and higher o
Pituitary adenylate cyclase activating polypeptide-38 (PACAP38) is a widely distributed neuropeptide involved in neuroprotection, neurodevelopment, nociception and inflammation. Moreover, PACAP38 is a potent inducer of migraine-like attacks, but the mechanism behind this has not been fully elucidated.Migraine is a neurovascular disorder, recognized as the second most disabling disease. Nevertheles
Innovation in retailing is under-investigated in academia and yet highly relevant in practice given the current changes in the retail landscape. Although retailing is often characterised by a dynamic and highly competitive environment, retail organizations are not often considered as “innovative,” at least when compared with manufacturing industries or when using existing innovation frameworks in
Collaborative networks are widely employed as mechanisms to develop innovative responses in challenging environments. This approach has relevance in the area of regional development particularly where food production and tourism are two significant sectors underpinning regions. These two industries have conventionally operated as single sectors independent of each other. However, an inability to r
The 1970s is a paradoxical decade. On the one hand, it marked the gradual demise of the industrial society and the end of the «Golden Age» of capitalism. On the other hand, the decade saw the renaissance of international banking and finance after almost half a century of retreat, thanks to the explosive growth of the Eurodollar market. International banking, which had remained dormant since the 19
We present two new data structures for computing values of an n-variate polynomial P of degree at most d over a finite field of q elements. Assuming that d divides q-1, our first data structure relies on (d+1)n+2 tabulated values of P to produce the value of P at any of the qn points using O(nqd2) arithmetic operations in the finite field. Assuming that s divides d and d/s divides q-1, our second
Because of the good thermal stability and superior carrier transport characteristics of formamidinium lead trihalide perovskite HC(NH2)2PbX3 (FAPbX3), it has been considered to be a better optoelectronic material than conventional CH3NH3PbX3 (MAPbX3). Herein, we fabricated a FAPbBr3 microcrystal-based photodetector that exhibited a good responsivity of 4000 A W−1 and external quantum efficiency up
Objective: To describe the longitudinal patterns of release, and investigate the association between a set of synovial fluid biomarkers at the acute and chronic stage and the development of radiographic knee osteoarthritis (OA) after an anterior cruciate ligament (ACL) injury. Design: Synovial fluid was aspirated from the acutely ACL-injured knee within the first 2weeks (acute samples), and yearly
HEIMDAL will be a multi length scale neutron scattering instrument for the study of structures covering almost nine orders of magnitude from 0.01 nm to 50 mm. The instrument is accepted for construction at the European Spallation Source (ESS) and features a variable resolution thermal neutron powder diffractometer (TNPD), combined with small angle neutron scattering (SANS) and neutron imaging (NI)
Background: Laparoscopic liver resection (LLR) appears to be safe and effective as open liver resection (OLR) for hepatocellular carcinoma (HCC). However, studies comparing LLR with ORL in elderly patients are limited. The purpose of this study is to compare the clinical outcomes of LLR versus OLR for HCC in elderly patients. Methods: A retrospective analysis was made comparing laparoscopic (n = 1
The kinetics for manganese-catalyzed autoxidation of sulfur(IV) (SO2.nH2O, HSO3-, SO32-) in aqueous solution has been studied spectrophotometrically at 25-degrees-C, 1 < pH < 4, [S(IV)] almost-equal-to 2.3 X 10(-5) M, 1 X 10(-6) M less-than-or-equal-to [Mn(II)] less-than-or-equal-to 1.5 X 10(-3) M, [Mn(III)] less-than-or-equal-to 4 X 10(-8) M, [O2] almost 2.5 X 10(-4) M, and low ionic strength.
