Wave Equations for Classical Two-Component Proca Fields in Curved Spacetimes with Torsionless Affinities

The world formulation of the full theory of classical Proca fields in generally relativistic spacetimes is concisely reviewed and the entire set of pertinent field equations is transcribed in a straightforward way into the framework of one of the Infeld-van der Waerden formalisms. Some well-known calculational techniques are then utilized for deriving the wave equations that control the propagation of the fields allowed for. It appears that no interaction couplings between such fields and electromagnetic curvatures are carried by the wave equations at issue. What results is, in effect, that the only interactions which ultimately occur in the theoretical context under consideration involve strictly Proca fields and wave functions for gravitons.Comment: Many improvements on the paper have still been made. In particular, its title has been modified so as to conform further to one of its main aim

Remembering the forgotten child: the role of immune checkpoint inhibition in patients with human immunod eficiency virus and cancer.

Patients with human immunodeficiency virus (HIV) infection have a high risk of developing virally-mediated cancers. These tumors have several features that could make them vulnerable to immune checkpoint inhibitors (ICIs) including, but not limited to, increased expression of the CTLA-4 and PD-1 checkpoints on their CD4+ T cells. Even so, HIV-positive patients are generally excluded from immunotherapy cancer clinical trials due to safety concerns. Hence, only case series have been published regarding HIV-positive patients with cancer who received ICIs, but these reports of individuals with a variety of malignancies demonstrate that ICIs have significant activity, exceeding a 65% objective response rate in Kaposi sarcoma. Furthermore, high-grade immune toxicities occurred in fewer than 10% of treated patients. The existing data suggest that the underlying biologic mechanisms that mediate development of cancer in HIV-infected patients should render them susceptible to ICI treatment. Preliminary, albeit limited, clinical experience indicates that checkpoint blockade is both safe and efficacious in this setting. Additional clinical trials that include HIV-positive patients with cancer are urgently needed

Kekayaan Yang Tidak Dapat Dipertanggungjawabkan (Illicit Enrichment) Sebagai Salah Satu Cara Dalam Memberantas Korupsi

Tujuan dilakukannya penelitian ini adalah untuk mengetahui bagaimana korupsi yang terjadi dikalangan penyelenggara negara dan bagaimana pembuktian harta kekayaan penyelenggara negara menurut Undang-Undang Tindak Pidana Korupsi. Dengan menggunakan metode penelitian yuridis normative, disimpulkan: 1. Kasus korupsi yang dilakukan oleh penyelenggara negara: Kasus tindak pidana korupsi yang menjadi sorotan adalah seorang pejabat publik yang ditangkap tangan (caught red-handed) menerima suap. Seperti DR. Patrialis Akbar, SH, MH mantan hakim Mahkamah Konstitusi (MK) yang ditangkap KPK. 2. 2. Pembuktian Terhadap Harta Kekayaan Menurut Undang-Undang Tindak Pidana Korupsi Pembuktian suatu fakta atau dalil yang diberikan beban untuk itu adalah pihak yang mengajukan suatu dalil atau fakta, dalam perkara pidana yang dimaksud adalah Jaksa Penuntut Umum. Selanjutnya dalam proses perkara yang berjalan, beban pembuktian tersebut digeser kepada terdakwa untuk melakukan pembuktian yang sebaliknya
