Cyclic Consumption and Replenishment Decisions for Vendor-Managed Inventory of Multisourced Parts in Dell's Supply Chain

Multisourcing and vendor-managed inventory (VMI) programs with percentage supply allocations (PSAs) are two common practices in the electronics industry. A PSA is a prenegotiated percentage of a multisourced part’s total demand, which should be provided by a supplier. For parts within Dell’s supply chain for which these practices are applicable, we provide a framework to implement pull-based replenishments, verify its feasibility, and demonstrate the potential benefits via simulation. Specifically, we investigate two decisions to meet customer demand and PSAs with minimal inventory: (1) how to allocate actual customer demand among multiple suppliers, and (2) what guidelines Dell should specify to suppliers for VMI hub replenishments. For demand allocations, we propose a consumption cycle based on the PSAs. We consider a heuristic replenishment policy and develop an algorithm to compute the policy parameters, which can be used as supplier guidelines. The proposed approach presents a significant opportunity for cost savings. Dell used the results of this project (1) to address skepticism toward a pull-based approach in managing VMI replenishments, (2) to gain stakeholder support to implement a pull-based approach, and (3) to emphasize the need for a change in Dell’s philosophy on managing demand allocations to suppliers and VMI hub replenishments.
On the ‘data stirring’ role of the dentate gyrus of the hippocampus

Abstract Understanding hippocampal (HC) function, as it is presently known, includes exploring the HC role in episodic memory storage. As pointed out by Teyler and DiScenna in the 1980s, the apparatus needed for recalling a stored episode, and awakening all its components in a coordinated manner, by necessity includes a triggering device able to reach each of the mental entities that must be awakened. In the context of neuronal networks, the triggering device in question takes the form of a large cell assembly, a separate one made for every new episode stored. The present paper deals with the creation and the properties of these cell assemblies (‘pointer groups’). To perform the function of episodic memory retrieval, each of these must possess the information capacity (entropy) enabling it to single out an episode and the network connections enabling it to reach all components of it; further, to deal with the unpredictability of the memory items it has to address, it must have its member neurons well distributed through the length of the network (the HC). The requirements imply that the creation of a pointer group must include a randomizing step analogous to ‘stirring’. It is argued that many of the known peculiarities of granule cells in the dentate gyrus arise as solutions to the practical problems presented by the creation of the pointer groups and the details of ‘stirring’, and so do a series of other features of the HC network, some of them only discovered in the last few years.
Capacity limits of bandlimited Gaussian channels in fractional Fourier domain

The well-known Shannon channel capacity theorem plays a fundamental role in modern wireless communications. However, this theorem, derived from the Fourier transform (FT) viewpoint, only holds for Fourier bandlimited Gaussian channels. It has already been shown that a signal can not be both Fourier bandlimited and fractional bandlimited with a certain angle α≠π/2. Hence, it is desirable to generalize the Shannon channel capacity theorem from Fourier bandlimited channels to fractional bandlimited ones. In this paper, we propose a formula to calculate the capacity limits of bandlimited Gaussian channels in the fractional Fourier domain. This formula is an extension of the Shannon channel capacity theorem for fractional bandlimited channels. The achieved results may be useful for designing communication systems in the fractional Fourier domain.
Individual and Relationship Characteristics of Adolescent Girls With Histories of Physical Dating Violence

The objective of this article is to examine the individual and relational characteristics of adolescent girls with a history of physical DV, as well as to utilize partner-specific, temporal data to explore links between these factors and recent or ongoing DV experiences. Participants were 109 high school girls (ages 14-17) identified as having a history of DV through a school-based screening procedure. Details regarding the timing of DV and links with specific dating partners were gathered using Timeline Followback (TLFB) interview methodology. At study entry, 30% endorsed clinical levels of depression symptoms and 89% reported delinquent behaviors. Forty-four percent reported vaginal intercourse in their lifetime and of those, 35% reported not using a condom at last sex. During the 90 days prior to study entry, 69% of youth reported having a romantic relationship and 58% of those youth reported physical/sexual violence. Data revealed that more physical/sexual violence was associated with longer relationship length, Wald χ2(2) = 1,142.63, p < . 001. Furthermore, depressive symptoms, not delinquency, contributed significantly to recent DV experiences, even when relationship length was controlled. Our findings suggest that prevention programs for this population should teach participants how to quickly recognize unhealthy relationship characteristics, as violence severity increases with relationship length. Programs for adolescent girls should also address depressive symptoms, which are linked to DV severity when other risks are taken into account. Finally, the TLFB calendar method appears useful for gathering the temporal and partner-specific data needed to understand the complexity of dating relationships and violence experiences in this population.

Numerical Simulation of 3D Dynamic Garment Pressure

This paper presents a mechanical model for numerical simulations of 3D dynamic garment pressure during wear using a finite element method. Based on analyzing the contact characteristics between the human body and the garment, a mechanical model is developed based on the theory of dynamic contact mechanics. The garment is regarded as an elastic shell of geometric nonlinearity and the human body is assumed to be rigid. The contact between body and garment is modeled as a dynamic sliding interface. A series of examples is presented to illustrate the simulation results of the computational model using commercial finite element software: a female human model wearing a set of perfectly fitting sportswear. The garments have the same style but are made from different materials: a cotton denim fabric and a knitted nylon fabric. Compared with values of measured garment pressure reported in the literature, the predicted pressure is close to the magnitude of experimental measurements, indicating that the model is able to simulate garment pressure during wear with reasonable accuracy. The computational model can simulate and predict the dynamic mechanical behavior of garments during wear, such as garment deformation, pressure, and internal stresses, without actually producing the garment.
Critical behavior in Fe-doped manganites

The critical properties of the manganese perov- skite La0.67Ba0.22Sr0.11Mn1-xFexO3 (0 B x B 0.2) around the paramagnetic (PM)-ferromagnetic (FM) phase transition were investigated using modified Arrott plots and Kouvel- Fisher method based on the data of static magnetic mea- surements recorded around the curie temperature TC. Based on the evaluated critical exponents for the compounds with different x values (0.378 B b B 0.411, 1.247 B c B 1.393, and 4.018 B d B 4.73) we concluded that the PM-FM phase transition in the compound with x = 0 belongs to the three- dimensional Heisenberg universality. However, the substi- tution of Fe 3? for Mn 3? resulted in shifting the value of c toward the 3D-Ising model value and a slight increase in b. This behavior was discussed and correlated with the random distribution of Fe 3? at the Mn 3? sites and the consequent
Cancer deaths and cases attributable to lifestyle factors and infections in China, 2013

Background The burden of cancer in China is high, and it is expected to further increase. Information on cancers attributable to potentially modifiable risk factors is essential in planning preventive measures against cancer. We estimated the number and proportion of cancer deaths and cases attributable to ever-smoking, second-hand smoking, alcohol drinking, low fruit/vegetable intake, excess body weight, physical inactivity, and infections in China, using contemporary data from nationally representative surveys and cancer registries. Methods The number of cancer deaths and cases in 2013 were obtained from the National Central Cancer Registry of China and data on most exposures were obtained from the China National Nutrition and Health Survey 2002 or 2006 and Global Adult Tobacco Smoking 2010. We used a bootstrap simulation method to calculate the number and proportion of cancer deaths and cases attributable to risk factors and their corresponding 95% confidence intervals (CIs), allowing for uncertainty in data. Results Approximately 718 000 (95% CI 702 100-732 200) cancer deaths in men and 283 100 (278 800-288 800) cancer deaths in women were attributable to the studied risk factors, accounting for 52% of all cancer deaths in men and 35% in women. The numbers for incident cancer cases were 952 500 (95% CI 934 200-971 400) in men and 442 700 (437 200-447 900) in women, accounting for 47% of all incident cases in men and 28% in women. The greatest proportions of cancer deaths attributable to risk factors were for smoking (26%), HBV infection (12%), and low fruit/vegetable intake (7%) in men and HBV infection (7%), low fruit/vegetable intake (6%), and second-hand smoking (5%) in women. Conclusions Effective public health interventions to eliminate or reduce exposure from these risk factors, notably tobacco control and vaccinations against carcinogenic infections, can have considerable impact on reducing the cancer burden in China.
Trends in blood pressure and body mass index among Chinese children and adolescents from 2005 to 2010.

BACKGROUND The prevalence of obesity, based on body mass index (BMI), among Chinese children and adolescents has increased for decades, but the relationship between trends in blood pressure (BP) and increasing BMI has not been studied. METHODS BMI and BP measurements of 391,982 children aged 7-17 years were obtained from surveys in 2005 and 2010. The mean change and 95% confidence intervals (CIs) of BP were calculated, and the association between BMI and BP was assessed by using analysis of covariance and direct adjustment with the BMI distribution of 2005 survey. RESULTS The mean systolic BP (SBP) and diastolic BP (DBP) increased 1.5 mm Hg (95% CI = 1.4-1.7 mm Hg) and 1.1 mm Hg (95%CI = 1.1-1.2 mm Hg) for boys and 1.2 mm Hg (95% CI = 1.1-1.3 mm Hg) and 1.0 mm Hg (95% CI = 1.0-1.1 mm Hg) for girls from 2005 to 2010, respectively. After adjustment for BMI, SBP and DBP in 2010 were 0.8mm Hg (95% CI = 0.8-0.9mm Hg) and 0.8mm Hg (95% CI = 0.7-0.8mm Hg) higher than in 2005, respectively (all P < 0.01). With adjustment for difference in BMI distribution in 2005 and 2010, the mean increase of SBP decreased by 40.5% and that of DBP by 26.9%. CONCLUSIONS BP among Chinese children and adolescents was on the rise from 2005 to 2010, which was consistent with the hypothesis that the rise in BP was in part attributable to the rise in BMI.
A SAT-based Decision Procedure for ALC

The goal of this paper is to describe and thoroughly test a decision procedure, called KSAT, checking satisfiability in the terminological logic A£C. KSAT is said to be SATbased as it is defined in terms of a decision procedure for propositional satisfiability (SAT). The tests are performed comparing KSAT with, among other procedures, KRIS, a state-of-the-art tableau-based implementation of a decision procedure for ALe. KSAT outperforms KRIS of orders of magnitude. Furthermore, the empirical results highlight an intrinsic weakeness that tableau-based decision procedures have with respect to SATbased decision procedures.

Aging is associated with a prefrontal lateral-medial shift during picture-induced negative affect

Abstract The capacity to adaptively respond to negative emotion is in part dependent upon lateral areas of the prefrontal cortex (PFC). Lateral PFC areas are particularly susceptible to age-related atrophy, which affects executive function (EF). We used structural and functional magnetic resonance imaging (MRI) to test the hypothesis that older age is associated with greater medial PFC engagement during processing of negative information, and that this engagement is dependent upon the integrity of grey matter structure in lateral PFC as well as EF. Participants (n = 64, 38–79 years) viewed negative and neutral scenes while in the scanner, and completed cognitive tests as part of a larger study. Grey matter probability (GMP) was computed to index grey matter integrity. FMRI data demonstrated less activity in the left ventrolateral PFC (VLPFC) and greater ventromedial PFC (VMPFC) activity with increasing age during negative-picture viewing. Age did not correlate with amygdala responding. GMP in VLPFC and EF were negatively associated with VMPFC activity. We conclude that this change from lateral to medial PFC engagement in response to picture-induced negative affect reflects decreased reliance on executive function-related processes, possibly associated with reduced grey matter in lateral PFC, with advancing age to maintain emotional functioning.
PVS: passive voltage scaling for wireless sensor networks

Recent wireless sensor nodes, equipped with ultra-low-power (ULP) RISC microcontrollers, do not generally support DVS (dynamic voltage scaling), though the ULP microcontrollers have ideal energy-voltage-frequency characteristics for DVS. In general, an output-adjustable DC-DC converter is hardly all affordable in such sensor nodes, and surprisingly light current consumption makes the DC-DC converter operate in a very inefficient region. This paper introduces a new supply voltage scaling namely PVS (passive voltage scaling) that eliminates the use of a DC-DC converter. While a battery is directly connected to a ULP microcontroller, PVS monitors the battery voltage drop (50% in alkaline batteries) and scales down the clock frequency accordingly for a reliable operation. Opposite to DVS, PVS does not achieve the optimal energy consumption of the microcontroller, but it minimizes the loss of the power delivery system, peripherals and battery, and achieves ultimate longer operational lifetime. Along with such energy gain, the throughput of a PVS-enabled sensor node continuously decreases by the battery state of charge loss, which makes a traditional performance-driven routing also energy-aware. We applied PVS to a wireless sensor network, and demonstrated 34% more network lifetime, and 26% shorter average latency over a modern sensor network such as Telos, 64% more network lifetime and 3% shorter average latency over a traditional sensor network with a DC-DC converter.
Autonomous analyser platforms for remote monitoring of water quality

This paper describes progress in the realization of reliable, relatively low-cost autonomous microfluidic analysers that are capable of monitoring the chemistry of water bodies for significant periods of time (weeks, months) without human intervention. The data generated is transmitted wireless to a remote web server and transferred to a web-database that renders data access location independent. Preliminary results obtained from a ‘matchbox’ scale analyzer are also presented and routes to the realization of next generation platforms discussed.

Genome‐wide map of Apn1 binding sites under oxidative stress in Saccharomyces cerevisiae

The DNA is cells is continuously exposed to reactive oxygen species resulting in toxic and mutagenic DNA damage. Although the repair of oxidative DNA damage occurs primarily through the base excision repair (BER) pathway, the nucleotide excision repair (NER) pathway processes some of the same lesions. In addition, damage tolerance mechanisms, such as recombination and translesion synthesis, enable cells to tolerate oxidative DNA damage, especially when BER and NER capacities are exceeded. Thus, disruption of BER alone or disruption of BER and NER in Saccharomyces cerevisiae leads to increased mutations as well as large‐scale genomic rearrangements. Previous studies demonstrated that a particular region of chromosome II is susceptible to chronic oxidative stress‐induced chromosomal rearrangements, suggesting the existence of DNA damage and/or DNA repair hotspots. Here we investigated the relationship between oxidative damage and genomic instability utilizing chromatin immunoprecipitation combined with DNA microarray technology to profile DNA repair sites along yeast chromosomes under different oxidative stress conditions. We targeted the major yeast AP endonuclease Apn1 as a representative BER protein. Our results indicate that Apn1 target sequences are enriched for cytosine and guanine nucleotides. We predict that BER protects these sites in the genome because guanines and cytosines are thought to be especially susceptible to oxidative attack, thereby preventing large‐scale genome destabilization from chronic accumulation of DNA damage. Information from our studies should provide insight into how regional deployment of oxidative DNA damage management systems along chromosomes protects against large‐scale rearrangements.

Characterization of Key Helicobacter pylori Regulators Identifies a Role for ArsRS in Biofilm Formation

ABSTRACT Helicobacter pylori must be able to rapidly respond to fluctuating conditions within the stomach. Despite this need for constant adaptation, H. pylori encodes few regulatory proteins. Of the identified regulators, the ferric uptake regulator (Fur), the nickel response regulator (NikR), and the two-component acid response system (ArsRS) are each paramount to the success of this pathogen. While numerous studies have individually examined these regulatory proteins, little is known about their combined effect. Therefore, we constructed a series of isogenic mutant strains that contained all possible single, double, and triple regulatory mutations in Fur, NikR, and ArsS. A growth curve analysis revealed minor variation in growth kinetics across the strains; these were most pronounced in the triple mutant and in strains lacking ArsS. Visual analysis showed that strains lacking ArsS formed large aggregates and a biofilm-like matrix at the air-liquid interface. Biofilm quantification using crystal violet assays and visualization via scanning electron microscopy (SEM) showed that all strains lacking ArsS or containing a nonphosphorylatable form of ArsR (ArsR-D52N mutant) formed significantly more biofilm than the wild-type strain. Molecular characterization of biofilm formation showed that strains containing mutations in the ArsRS pathway displayed increased levels of cell aggregation and adherence, both of which are key to biofilm development. Furthermore, SEM analysis revealed prevalent coccoid cells and extracellular matrix formation in the ArsR-D52N, ΔnikR ΔarsS, and Δfur ΔnikR ΔarsS mutant strains, suggesting that these strains may have an exacerbated stress response that further contributes to biofilm formation. Thus, H. pylori ArsRS has a previously unrecognized role in biofilm formation. IMPORTANCE Despite a paucity of regulatory proteins, adaptation is key to the survival of H. pylori within the stomach. While prior studies have focused on individual regulatory proteins, such as Fur, NikR, and ArsRS, few studies have examined the combined effect of these factors. Analysis of isogenic mutant strains that contained all possible single, double, and triple regulatory mutations in Fur, NikR, and ArsS revealed a previously unrecognized role for the acid-responsive two-component system ArsRS in biofilm formation.
Joint BS-User Association, Power Allocation, and User-Side Interference Cancellation in Cell-free Heterogeneous Networks

Future wireless networks are expected to be heterogeneous with dense deployment of pico (small cell) base stations (BSs) overlaid with traditional macro BSs. There are two performance bottlenecks in such heterogeneous networks (HetNet): the interference issue and cell-edge effect. We propose to combine cell-free BS-user association (BUA), power control, and dynamic user-side interference cancellation (IC) to mitigate these bottlenecks. By dynamically selecting the “best” serving BSs for each user, the cell-free BUA can exploit the multi-BS diversity gain to mitigate the interference and cell-edge effect. Furthermore, the user-side IC eliminates the strong cross-tier interference. We formulate the joint optimization of cell-free BUA, power allocation, and user-side IC as a weighted sum-rate (WSR) maximization problem, and propose a WMMSE alternating optimization algorithm to solve it. Specifically, a generalized WMMSE method is proposed to solve the power optimization subproblem with nondifferentiable WSR function. Furthermore, by exploiting the specific problem structure, low complexity search methods are designed to find the optimal solutions of the combinatorial cell-free BUA and user-side IC subproblems. The proposed algorithm is shown to converge to a stationary solution of the joint problem. Simulations verify the significant gain of the proposed solution over existing solutions.
VIPE: A new interactive classification framework for large sets of short texts - application to opinion mining

This paper presents a new interactive opinion mining tool that helps users to classify large sets of short texts originated from Web opinion polls, technical forums or Twitter. From a manual multi-label pre-classification of a very limited text subset, a learning algorithm predicts the labels of the remaining texts of the corpus and the texts most likely associated to a selected label. Using a fast matrix factorization, the algorithm is able to handle large corpora and is well-adapted to interactivity by integrating the corrections proposed by the users on the fly. Experimental results on classical datasets of various sizes and feedbacks of users from marketing services of the telecommunication company Orange confirm the quality of the obtained results.
