Authors: Barin Ioana 
Published: January 2018

RCM is a methodology through which are described the details of identification and clustering (classification) the outlets, and the customers who visit them. Classification is based on various<br />criteria, which concern both the seller and the buyer. The information resulted from classification makes possible the clustering of different locations which help improve planning<br />and resource allocation, organize the activities and evaluation decisions. This article’s purpose is to provide clear information as regards: outletsr classification methodology, the importance<br />of implementation, basic information vs. value-added information, data accuracy and maintainance of information The role of this methodology is to provide clear methods for classification and grouping the locations, based on the identification of clients and retailers.values/ similar needs.

Authors: Pacurari Doina , Muntean Mircea 
Published: January 2018

Important indicator, used in performance analysis, value added expresses enterprise’s contribution to national gross domestic product. The value added through economic activity developed by enterprise should assure the remuneration of all its life participants: employees, investors, state and enterprise itself. Information referring to enterprise capacity of generating<br />value added should be based on decisions concerning future enterprise decisions. The present article presents, by means of a case study, value added calculation (by subtractive and additive<br />method) and their analysis.
Consideration on the price stability – financial stability relationship in the context of financial globalization
Authors: Apostoaie Marius 
Published: January 2018

This study is focused upon the involvement of the central banks regarding the fulfillment of the two main objectives: price stability and financial stability. These two key concepts are part of an old and ongoing debate that the current turmoil has revived, and that is whether monetary policy should aim, or not, at ensuring financial stability in parallel to its main objective of price stability. On both sides there are solid and well known arguments. In the beginning of the study I have considered a literature review with regard to price and financial stability issues. After that I have tried to shed some light (from a theoretical point of view) on the nature and dynamics of the fundamental interlinkages between the two aspects and there implications on the central banks and the economy. Finally I outline some general conclusions that have emerged in the present study.
Restrictions on complement anaphora
Authors: Schmitt Viola , Onea Edgar , Buch Friederike 
Published: January 2018

This paper discusses the semantic status and the restrictions on complement anaphora, i.e. pronouns that are anaphorically related to quantifiers and seem to refer to the `complement set' of the latter -- the set of those individuals that are in the restrictor but not in the nuclear scope of the quantifier. Our main empirical point, motivated by data from German, is that contrary to the claims in the literature, true complement set reference is not exclusively determined by the logical properties of the quantifier but also by its the syntactic context. Based on this observation, we argue that plural quantifiers provide anaphoric antecendents by a particular inference mechanism, which is sensitive to syntactic information: We submit that speakers employ verifying strategies for sentences with plural quantifiers where a `test' discourse referent is inserted in the `syntactic slot' the plural quantifier originally occurs in. If a discourse referent, when inserted in this slot, yields truth-conditions for the resulting sentence that are equivalent to those of the original sentence, it can be used as an antecendent for anaphora.
Quantifying Weak Nonthermal Solar Radio Emission at Low Radio Frequencies
Authors: Sharma Rohit , Oberoi Divya , Arjunwadkar Mihir 
Published: January 2018

Abstract
The recent availability of fine-grained high-sensitivity data from the new generation of low radio frequency instruments such as the Murchison Widefield Array (MWA) has opened up opportunities for using novel techniques for characterizing the nature of solar emission at these frequencies. Here we use this opportunity to look for evidence for the presence of weak nonthermal emissions in the 100–240 MHz band, at levels weaker than have been probed so far. The presence of such features is believed to be a necessary consequence of nanoflare-based coronal and chromospheric heating theories. We separate the calibrated MWA solar dynamic spectra into a slowly varying and an impulsive, and hence nonthermal, component. We demonstrate that Gaussian mixture modeling can be used to robustly model the latter, and we estimate the flux density distribution as well as the prevalence of impulsive nonthermal emission in the frequency-time plane. Evidence for the presence of nonthermal emission at levels down to ∼0.2 SFU (1 SFU = 104 Jy) is reported, making them the weakest reported emissions of this nature. Our work shows the fractional occupancy of the nonthermal impulsive emission to lie in the 17%–45% range during a period of medium solar activity. We also find that the flux density radiated in the impulsive nonthermal emission is very similar in strength to that of the slowly varying component, which is dominated by thermal bremsstrahlung. Such significant prevalence and strength of the weak impulsive nonthermal emission has not been appreciated before.
On the Nature of Ultra-faint Dwarf Galaxy Candidates. I. DES1, Eridanus III, and Tucana V

We use deep Gemini/GMOS-S g, r photometry to study the three ultra-faint dwarf galaxy candidates DES1, Eridanus III (Eri III), and Tucana V (Tuc V). Their total luminosities, M

V
(DES1) = −1.42 ± 0.50 and M

V
(Eri III) = −2.07 ± 0.50, and mean metallicities,

and

, are consistent with them being ultra-faint dwarf galaxies, as they fall just outside the 1σ confidence band of the luminosity–metallicity relation for Milky Way satellite galaxies. However, their positions in the size–luminosity relation suggest that they are star clusters. Interestingly, DES1 and Eri III are at relatively large Galactocentric distances, with DES1 located at

and Eri III at

. In projection, both objects are in the tail of gaseous filaments trailing the Magellanic Clouds and have similar 3D separations from the Small Magellanic Cloud (SMC):

kpc and

kpc, respectively. It is plausible that these stellar systems are metal-poor SMC satellites. Tuc V represents an interesting phenomenon in its own right. Our deep photometry at the nominal position of Tuc V reveals a low-level excess of stars at various locations across the GMOS field without a well-defined center. An SMC Northern Overdensity–like isochrone would be an adequate match to the Tuc V color–magnitude diagram, and the proximity to the SMC (12.°1;

kpc) suggests that Tuc V is either a chance grouping of stars related to the SMC halo or a star cluster in an advanced stage of dissolution.

Abstract
We report L-band VLA observations of 1RXS J0603.3+4214, a cluster that hosts a bright radio relic, known as the Toothbrush, and an elongated giant radio halo. These new observations allow us to study the surface brightness distribution down to 1 arcsec resolution with very high sensitivity. Our images provide an unprecedented detailed view of the Toothbrush, revealing enigmatic filamentary structures. To study the spectral index distribution, we complement our analysis with published LOFAR and GMRT observations. The bright “brush” of the Toothbrush shows a prominent narrow ridge to its north with a sharp outer edge. The spectral index at the ridge is in the range −0.70 ≤ α ≤ −0.80. We suggest that the ridge is caused by projection along the line of sight. With a simple toy model for the smallest region of the ridge, we conclude that the magnetic field is below 5 μG and varies significantly across the shock front. Our model indicates that the actual Mach number is higher than that obtained from the injection index and agrees well with the one derived from the overall spectrum, namely

. The radio halo shows an average spectral index of α = −1.16 ± 0.05 and a slight gradient from north to south. The southernmost part of the halo is steeper and possibly related to a shock front. Excluding the southernmost part, the halo morphology agrees very well with the X-ray morphology. A power-law correlation is found between the radio and X-ray surface brightness.

This paper sets up a frame work modeling the optimal path of industrial pollution abatement under tradable permit and seawater cleaning project. Three sub-models are set up which reveal pollution-fish stock interaction, industrial pollution abatement under tradable permit, seawater cleaning project, respectively. Then in next session we introduce dynamic optimization problem which combines contains two state equations, which correspond to two state variables fish stock and pollution stock , respectively; four control variables industrial production , volume of pollution abatement , volume of sea water cleaning and catch of fish , respectively. To maximum benefit of fishery, we follow and introduce the optimal solution of four control variables obtained from dynamic optimization.
Evaluating the Effectiveness of One-on-One Conversations to Increase Colorectal Cancer Screening in a Community-Based Clinical Setting
Authors: Fleming Tyler J. , Benitez Martha G. , Weintraub Miranda L. Ritterman 
Published: January 2018

Abstract

Context
The American Cancer Society's 80% by 2018 initiative aims to increase at-home colorectal cancer (CRC) screening.

Objective
To assess the effectiveness of one-on-one conversations with patients about CRC screening on compliance with at-home fecal immunochemical tests (FITs).

Setting
Federally funded health care center serving a largely minority, urban, underserved population in Vallejo, California.

Methods
Patients aged 50 to 75 years were divided into 3 main intervention arms: (1) patients who received a one-on-one in-person consultation to discuss the need for CRC screening and the screening process, as well as a FIT; (2) patients who received a telephone call to discuss the need for CRC screening and the screening process before receiving a FIT in the mail; and (3) patients who were mailed a FIT with a letter explaining the importance of completing the FIT and instructions. The FITs were tracked to see if they were returned to the laboratory for processing, and the rates of return were compared in bivariate analyses using t and χ2 tests and in adjusted analyses using logistic regression with bootstrapping.

Results
A total of 3415 patients were included in the study. One-on-one conversations either in person (OR, 24.63; 95% CI, 19.28-31.46) or via telephone (OR, 14.74; 95% CI, 10.96-19.82) were more effective at getting patients to complete the at-home CRC screening than not having one-on-one conversations before receiving the FIT.

Conclusion
Patients may be more likely to complete at-home FITs to screen for CRC if they are first able to discuss the need for screening and the screening process with a health care professional.
Nephroblastoma Arising in a Primary Testicular Teratoma in a Nonatrophic Testis of a 50-Year-Old Man
Authors: Kromka Joseph J. , Turner Kevin , Elisco Anthony , Hale Nathan 
Published: January 2018

Abstract
Extrarenal nephroblastoma is an extremely rare tumor thought to be related to teratoid tumors of germ cell origin. Because few cases have been reported, no standard method for categorizing and managing these tumors exists. To our knowledge, there have only been 3 adult cases of nephroblastoma arising in a germ cell tumor of testicular origin in a nonatrophic testis, all in men aged 19 to 22 years and with aggressive clinical courses. We report a case of nephroblastoma in a nonatrophic testis, with nephroblastoma being the only non–germ cell component, in an older patient and with a more indolent clinical course that was responsive to localized treatment.

Published: October 2024

ImportanceSince fibroblast growth factor receptor inhibitors (FGFRi) are used for treatment of intrahepatic cholangiocarcinoma (iCCA), understanding potential complications following longer-term use in clinical practice settings is warranted. This study describes cataract formation or progression as a complication of FGFRi use for the treatment of iCCA, even after treatment discontinuation.ObjectiveTo describe cases of cataract formation or worsening in patients with iCCA treated with FGFRi and to characterize the ophthalmologic features, risk factors, and outcomes for FGFRi-associated cataracts.Design, Setting, and ParticipantsThis retrospective case series study used data from patients with iCCA harboring FGFR2 aberrations who received FGFRi in clinical trials or as standard therapy from the University of California, San Francisco, Hepatobiliary Tissue Bank and Registry. Data were collected from patient visits between February 2015 and October 2021, and this retrospective investigation was conducted from September 6, 2022, to May 4, 2023. Data analysis was conducted from May 5, 2023, to September 6, 2023.ExposureUse of an FGFRi for the treatment of iCCA.Main Outcomes and MeasuresThe primary outcome was designated as development of a new or worsening cataract after FGFRi initiation. Statistical analysis for the association between cataract formation and clinical covariates was performed using unpaired t tests and Fisher exact tests. A single bivariate logistic regression model was used to examine total duration of FGFRi therapy and age at the conclusion of FGFRi therapy as predictors of cataract development.ResultsA total of 18 patients were included in the study; median (range) patient age was 54 (27-81) years, and 13 patients (72%) were female. Nine patients (50%) developed a cataract or had cataract progression in at least 1 eye after initiation of FGFRi. Of 17 eyes with cataract, 8 eyes (47%) required cataract surgery. One patient rapidly developed a cataract associated with phacomorphic glaucoma, which required urgent surgery. The median (range) time to cataract onset or worsening from initiation of FGFRi was approximately 18 (1-23) months. Five of 9 patients (56%) who developed cataracts or had cataract progression were diagnosed with new or worsening cataracts after discontinuation of FGFRi. Patients who developed cataracts had longer median (range) duration of FGFRi treatment compared with patients who did not develop cataracts (13 months [2-26] vs 5 months [1-11]; odds ratio, 1.01; 95% CI, 1.00-1.02; P = .02).Conclusions and RelevanceWhile this retrospective case series study cannot prove cause and effect conclusively due to the study design, study results highlight cataract formation or progression as a potential adverse effect of FGFRi therapy, supporting consideration of periodic eye examinations in patients who have received this treatment.
Dosimetric consequences of adapting the craniocaudal isocenter distance to daily patient position in craniospinal irradiation using volumetric modulated arc therapy

Published: October 2024

AbstractPurposeIn craniospinal irradiation, two or three isocenter groups along the craniocaudal axis are required to cover the long treatment target. Adapting the isocenter distance according to daily deviations in patient position is challenging because dosimetric hot or cold spots may occur in the field junction. The aim of this study was to quantify the effect of adapting the isocenter distance to patient position on the dose distribution of the field overlap region in craniospinal irradiation using partial‐arc volumetric modulated arc therapy.MethodsThe magnitude of isocenter distance deviations in craniocaudal direction was quantified by registering the setup images of 204 fractions of 12 patients to the planning images. The dosimetric effect of these deviations was determined by shifting the isocenters of the original treatment plan and calculating the resulting dose distribution.ResultsOn fraction‐level, deviations larger than 3 mm caused more than 5 percentage point changes in the doses covering 2% (D2%) and 98% (D98%) of the junction volume in several patients. On treatment course‐level, the changes in D2% and D98% of the junction volume were less than 5 percentage points in all cases except for one patient.ConclusionsCraniocaudal isocenter distance adaptation can be conducted provided that the mean isocenter distance deviation over the treatment course is within 3 mm.

AbstractMisfit‐layered calcium cobaltite [Ca2CoO3‐δ]0.62[CoO2] is an outstanding p‐type semiconducting thermoelectric with strong anisotropic properties. Texture engineering is crucial for enhancing its thermoelectric performance in polycrystalline ceramics. The in‐plane orientation of the grains improves the Seebeck coefficient and electrical conductivity, while the multi‐scale parallel interfaces scatter phonons and reduce thermal conductivity. Here, a tandem process of spark plasma sintering and edge‐free spark plasma texturing is used to produce dense and highly textured calcium cobaltite ceramics. The resulting ceramic shows a high degree of texturization, secondary phases, and enhanced electrical conductivity of 246 S cm−1 together with a strongly improved Seebeck coefficient of 224 µV K−1 at 1073 K. High grain ordering leads to carrier mobility of 0.49 cm2 V−1 s−1, which has a positive effect on both parameters. With a power factor of 12.4 µW cm−1 K−2 at 1073 K in air, previous thermoelectric performances of calcium cobaltite are surpassed, regardless of its form: pristine, doped, or composite. By combining the high power factor with a relatively low thermal conductivity, a remarkable figure‐of‐merit of 0.49 at 1073 K in air is obtained for the textured polycrystalline ceramic, which reaches 60 % of the figure‐of‐merit of a calcium cobaltite single crystal.

Published: October 2024

AbstractCalcium‐ion batteries are emerging as a promising alternative to lithium‐ion batteries by offering potential advantages in cost, affordability, and safety. However, the development of high‐performance calcium batteries has been hindered by the lack of high‐capacity cathodes. Here a small molecular organic cathode, 9,10‐phenanthrenequinone (PQ), is reported which leverages the rapid enolization chemistry of multi‐redox centers (C═O) and the flexible intermolecular structure for high performance. The PQ cathode demonstrates an impressive specific capacity of 250 mAh g−1 at 0.2 C for 200 cycles and superior rate capabilities. The robust performance of PQ cathodes is attributed to the mitigation of small molecule electrode dissolution in the weakly solvating ether electrolytes and the promotion of inter‐and intralayer Ca ion diffusion pathways, which synergistically facilitate the retention of high capacities at elevated current rates. When paired with a Ca metal anode, the full cell achieves remarkable capacities of 214 mAh g−1 at 0.2 C, with an average operating voltage of 2.5 V versus Ca/Ca2+, representing the highest performance among CMBs reported to date. The use of organic cathodes in tailored electrolytes with restricted intermediate dissolutions heralds a new era in the development of multivalent metal batteries.
“Back‐to‐Back” Radial Layered Skeleton Converging Heat Flow to Assist in Thermal Conduction of Aramid Nanofibers/Graphene Phase Change Composite Materials

Published: October 2024

AbstractAlthough optimizing the design of thermal conductive frameworks to promote the collection, transportation, and storage of thermal energy in composite phase change materials (CPCMs) is widely studied, the research on oriented layered thermal conductive frameworks is still in the exploratory stage. Taking inspiration from the bidirectional ice template strategy, a new research approach is proposed on the influence of “oriented micro‐unit” in thermal conductivity frameworks on the photothermal mass transfer of CPCMs. Three aramid nanofibers graphene nanosheets aerogels with different “oriented micro‐unit” structures are prepared by the high‐energy ball milling and bidirectional freezing. The enthalpy values of the composite materials are within the range of 146–152 J g−1. Photothermal conversion experiments, hot plate mass transfer experiments, solar‐thermal‐electric energy conversion experiments and multi‐physics field simulation analysis jointly show that the CPCMs with a “back‐to‐back” radial layered structure behaves the most outstanding photothermal conversion ability and heat transfer performance, with an increase in thermal conductivity of 173.3%, a photothermal conversion efficiency of 91.9%, and the maximum solar‐thermal‐electric output voltage of 303.3 mV. The design of “oriented micro‐unit” opens up new ideas for CPCMs in the field where directional heat transfer is required.
