A Counterexample to a Conjecture of D. B. Fuks
In [3] D. B. Fuks defined a duality of functors in the category
of weak homotopy types. In general this duality is
more difficult to work with than the duality of functors of the category
of pointed Kelley spaces [2]. It happens however
that all so-called strong functors [2] F of induce functors of
, and if we denote the duality operators of
and by
and D respectively, then there are many cases where

Timing of Perioperative Chemotherapy Does Not Influence Long-Term Outcome of Patients Undergoing Combined Laparoscopic Colorectal and Liver Resection in Selected Upfront Resectable Synchronous Liver Metastases
Background: The aim of this study was to compare patients undergoing combined colorectal and hepatic surgery with and without neoadjuvant chemotherapy to clarify the prognostic advantage of preoperative oncological treatment in a case-matched analysis using propensity scores and to identify factors predictive of good prognosis in a selected population of Synchronous ColoRectal Liver Metastases (SCRLM). Methods: A total of 73 patients who underwent upfront elective combined surgery without preoperative CT for SCRLM in two European tertiary referral centers were selected and constituted the study group (NoNACT group). The NoNACT group was matched (ratio 1:1) with patients who were operated after chemotherapy with neoadjuvant intent (NACT group, the control group). The matching was achieved based on six covariates representative of patients and disease characteristics. Results: While the characteristics of both colorectal and hepatic procedures were similar, the NoNACT group, as compared to the NACT group, had lower blood loss (200 mL vs. 550 mL). Postoperative stay (9 vs. 12 days) and morbidity rate (24.7% vs. 32.9%) were reduced in the NoNACT compared with the NACT group. Mid- and long-term outcomes were comparable. At multivariable analysis, predictors of long-term outcome were: right colonic neoplasms, RAS mutational status, CRS score ≥3 and the absence of perioperative chemotherapy. Conclusion: Preoperative neoadjuvant chemotherapy in patients with colorectal cancer and synchronous resectable liver metastases does not influence the risk of recurrence in patients with favorable tumor biology, while it was associated with increased intraoperative blood loss and morbidity. There is no strong evidence to recommend upfront chemotherapy in the absence of negative prognostic factors

Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Monotops at the LHC
We explore scenarios where top quarks may be produced singly in association with missing energy, a very distinctive signature, which, in analogy with monojets, we dub monotops. We find that monotops can be produced in a variety of modes, typically characterized by baryon number-violating or flavorchanging neutral interactions. We build a simplified model that encompasses all the possible (tree-level) production mechanisms and study the LHC sensitiveness to a few representative scenarios by considering fully hadronic top decays. We find that constraints on such exotic models can already be set with 1 fb-1 of integrated luminosity collected at √s=7 TeV
[Newspaper Clipping: Author Claims Evidence of Second JFK Assassin #1]
Newspaper article titled "Author Claims Evidence of Second JFK Assassin." The article states that author Richard J. Whalen concluded "that there is circumstantial evidence to support the theory of a second assassin in the shooting of President John F. Kennedy.
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
The desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
Jersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
