• Exercises in Classical Ring Theory

This is a book I wished I had found when, many years ago, I first learned the subject of ring theory. All those years have flown by, but I still did not find that book. So finally I decided to write it myself. All the books I have written so far were developed from my lectures; this one is no exception. After writing A First Course in Noncommutative Rings (Springer-Verlag GTM 131, hereafter referred to as “FC ”), I taught ring theory in Berkeley again in the fall of 1993, using FC as text. Since the main theory is already fully developed in FC, I asked my...

• Báo cáo " The total specialization of modules over a local ring"

In this paper we introduce the total specialization of an finitely generated module over local ring. This total specialization preserves the Cohen-Macaulayness, the Gorensteiness and Buchsbaumness of a module. The length and multiplicity of a module are studied. 1. Introduction Given an object defined for a family of parameters u = (u1, . . . , um ) we can often substitute u by a family α = (α1, . . . , αm) of elements of an infinite field K to obtain a similar object which is called a specialization. The new object usually behaves like the given object...

• Báo cáo "A NEW NUMERICAL INVARIANT OF ARTINIAN MODULES OVER NOETHERIAN LOCAL RINGS "

Let (R, m) be a commutative Noetherian local ring the maximal ideal and A an Artinian R-module with Ndim A = d. For each system of parameters x (x1 , ..., xd ) of A, we denote by e(x, A) the multipility of A with respect to x. Let n (n1 , n2 , ..., nd ) be a d-tuple of positive integers. The paper concerns to the function d-variables I(x(n); A) := where

• TELEPHONE TECHNIQUES

Depending on your perspective, the word telemarketing can conjure up very different images. As a business owner selling to consumers or other businesses, telemarketing may be a solution for vastly improving sales, generating greater suc- cess, and greatly expanding the reach of your business without ever leaving the comfort of your office. If you’re a consumer sitting at home trying to relax when the phone rings at the most inopportune time, that same word can conjure up feelings of annoyance, frustration, or fear of being caught up in some type of scam....

• Đề tài " The local converse theorem for SO(2n+1) and applications "

In this paper we characterize irreducible generic representations of SO2n+1 (k) (where k is a p-adic ﬁeld) by means of twisted local gamma factors (the Local Converse Theorem). As applications, we prove that two irreducible generic cuspidal automorphic representations of SO2n+1 (A) (where A is the ring of adeles of a number ﬁeld) are equivalent if their local components are equivalent at almost all local places (the Rigidity Theorem); and prove the Local Langlands Reciprocity Conjecture for generic supercuspidal representations of SO2n+1 (k). ...

• Fundamentals of Mechanical Ventilation

A gate valve is a linear motion valve used to start or stop fluid flow; however, it does not regulate or throttle flow. The name gate is derived from the appearance of the disk in the flow stream. Figure 4 illustrates a gate valve. The disk of a gate valve is completely removed from the flow stream when the valve is fully open. This characteristic offers virtually no resistance to flow when the valve is open. Hence, there is little pressure drop across an open gate valve. When the valve is fully closed, a disk-to-seal ring contact surface exists for 360°, and good sealing is...

• Báo cáo khoa học: The ROQUIN family of proteins localizes to stress granules via the ROQ domain and binds target mRNAs

Roquin is an E3 ubiquitin ligase with a poorly understood but essential role in preventing T-cell-mediated autoimmune disease and in microRNA-mediated repression of inducible costimulator (Icos) mRNA. Roquin and its mammalian paralogue membrane-associated nucleic acid binding protein (MNAB) define a protein family distinguished by an 200 amino acid domain of unknown function, ROQ, that is highly conserved from mam-mals to invertebrates and is flanked by a RING-1 zinc finger and a CCCH zinc finger....

• Báo cáo khoa học: The allene oxide cyclase family of Arabidopsis thaliana – localization and cyclization

Jasmonates are derived from oxygenated fatty acids (oxylipins) via the octadecanoid pathway and are characterized by a pentacyclic ring struc-ture. They have regulatory functions as signaling molecules in plant devel-opment and adaptation to environmental stress.

• Báo cáo Y học: Membrane embedded location of Na+ or H+ binding sites on the rotor ring of F1F0 ATP synthases

Recent crosslinking studies indicated the localization of the coupling ion binding site in the Na + -translocating F1F0 ATP synthase ofIlyobacter tartaricus within the hydrophobic part of the bilayer.Similarly, a membrane embedded H + -binding site is accepted for the H + -trans-locating F1F0 ATP synthase ofEscherichia coli.For a more definite analysis, we performed parallax analysis of fluorescence quenching with ATP synthases from both I. tartaricus and E. coli.

• Báo cáo Y học: Intracellular localization and transcriptional regulation of tumor necrosis factor (TNF) receptor-associated factor 4 (TRAF4)

To gain insight in the subcellular localization of tumor necrosis factor receptor-associated factor (TRAF4) we analyzed GFP chimeras of full-length TRAF4 and various deletionmutants derived thereof.While TRAF4–GFP (T4– GFP) was clearlylocalized in the cytoplasm, the N-terminal deletion mutant, T4(259–470), comprising the TRAF domain of the molecule, and a C-terminal deletion mutant consisting mainlyof the RING and zinc finger domains of TRAF4 were both localized predominantlyto the nucleus....

• Koszul homology annihilators with respect to distinguished D sequences

Let (R, m) be a Noetherian local ring and M a finitely generated R-module of dimension d. Let x = (x1, . . . , xd) be a system of parameters of M. In this paper, we give some applications of dd-sequences in the study of certain Koszul homology modules. Recall that the notion of dd-sequence was introduced by N. T. Cuong and D. T. Cuong [4], which is a distinguished type of d-sequence defined by C. Huneke.
