A Distributed Learning Scheme for Variational Quantum Algorithms
یک طرح یادگیری توزیع شده برای الگوریتم های کوانتومی متغیر-2022 Variational quantum algorithms (VQAs) are prime contenders to gain computational advantages over classical algorithms using near-term quantum machines. As such, many endeavors have been made
to accelerate the optimization of modern VQAs in past years. To further improve the capability of VQAs,
here, we propose a quantum distributed optimization scheme (dubbed as QUDIO), whose back ends support
both real quantum devices and various quantum simulators. Unlike traditional VQAs subsuming a single
quantum chip or simulator, QUDIO collaborates with multiple quantum machines or simulators to complete
learning tasks. In doing so, the required wall-clock time for optimization can be continuously reduced by
increasing the accessible computational resources when ignoring the communication and synchronization
time. Moreover, through the lens of optimization theory, we unveil the potential factors that could affect
the convergence of QUDIO. In addition, we systematically understand the ability of QUDIO to reduce
wall-clock time via two standard benchmarks, which are hand-written image classification and the ground
energy estimation of the dihydrogen. Our proposal facilitates the development of advanced VQAs to narrow
the gap between the state of the art and applications with the quantum advantage.

Pregnancy rates to fixed-time AI in Bos indicus-influenced beef cows using PGF2a with (Bee Synch I) or without (Bee Synch II) GnRH at the onset of the 5-day CO-Synch þ CIDR protocol
نرخ حاملگی به هوش مصنوعی با زمان ثابت در گاوهای گوشتی تحت تأثیر علامت Bos با استفاده از PGF2a با (Bee Synch I) یا بدون (Bee Synch II) GnRH در آغاز پروتکل 5 روزه CO-Synch þ CIDR-2020 Objectives were to 1) characterize fixed-time AI (FTAI) pregnancy rates using the 5-Day CO-Synch þ CIDR
protocol in mature, suckled Bos indicus-influenced beef cows, 2) compare FTAI pregnancy rates in the
latter to a modified version (5-Day Bee Synch þ CIDR; Bee Synch I) that included treatment with
prostaglandin F2a (PGF2a) at CIDR insertion on Day 0, and 3) test the hypothesis that elimination of both
GnRH-1 at the onset of synchronization and the double dose of PGF on Day 5 (Bee Synch II) would not
reduce FTAI pregnancy rates compared to Bee Synch I. For Experiment 1-trial 1, Brahman x Hereford (F-1)
cows (n ¼ 168) at least 40 d postpartum (PP; r ¼ 40e92 d) at the time of CIDR insertion were administered
the 5-Day CO-Synch þ CIDR protocol with FTAI at 72 h after CIDR removal. Pregnancy rates to
FTAI averaged 34.9 ± 1.9%. In Experiment 1-trial 2, fall- and spring-breeding Brahman x Hereford (F-1)
beef cows (n ¼ 269) were stratified by days PP and assigned randomly to receive either the 5-Day COSynch
þ CIDR (n ¼ 136) or Bee Synch I (n ¼ 133) protocol, with FTAI at 66 h after CIDR removal.
Pregnancy rate to FTAI was greater (P < 0.05) in Bee Synch I (52.6 ± 0.9%) than in the 5-Day COSynch
þ CIDR procedure (40.4 ± 5.7%). For Experiment 2, 422 mature Braford, Brangus, Nelore x
Brahman, and Brahman crossbred cows (Bos indicus proportion unknown) at 4 locations were treated
with Bee Synch I, with FTAI at 66 h. Overall FTAI pregnancy rate averaged 51.7 ± 2.1%. Finally, from 2013
through spring 2018, we used a switchback design using fall- and spring-breeding herds to compare Bee
Synch I (402 observations) to Bee Synch II (393 observations). Overall frequency of detected estrus at 66 h
using ESTROTECT™ breeding indicator patches was 57.2 ± 2.4%, conception rates of those detected in
estrus was 64.4 ± 3.5%, and FTAI pregnancy rates averaged 52.3 ± 2.4%, none of which differed between
treatments. Moreover, pregnancy rates to FTAI in both treatments did not differ in cows synchronized
between 40 and 80 d PP but increased after 80 d PP (P < 0.05). Bee Synch II, which eliminates GnRH-1 and
the double dose of PGF2a on Day 5, results in FTAI pregnancy rates essentially identical to Bee Synch I but
reduces synchronization costs and avoids the need for off-label (double dose PGF2a) drug use. Keywords: 5-Day CO-Synch þ CIDR | Prostaglandin F2a | GnRH | Bos indicus | Bee synch |

Progesterone-based timed AI protocols for Bos indicus cattle I: Evaluation of ovarian function
پروتکل های هوش مصنوعی بهنگام مبتنی بر پروژسترون برای گاو Bos indicus cattle I: ارزیابی عملکرد تخمدان-2020 Three experiments evaluated ovarian dynamics and circulating progesterone (P4) during P4-based
protocols initiated with GnRH, estradiol benzoate (EB), or no additional treatment in Nelore (Bos indicus)
cattle. In Exp 1 (n ¼ 59 cows), a 5-d P4-only protocol (P-5d; D0: P4 implant alone (1g); D5: P4
removal, 0.5 mg estradiol cypionate [EC], 0.526 mg cloprostenol [PGF], and 300 IU equine chorionic
gonadotropin [eCG]; D7: 8.4 mg buserelin acetate [GnRH]) was compared to a 9d protocol initiated with
EB (EB-9d; D0: 2 mg EB þ P4; D9: P4 removal þ EC þ PGF þ eCG), and to a 7d GnRH protocol (G-7d; D0:
16.8 mg GnRH þ P4; D6: PGF þ eCG; D7: P4 removal þ PGF; D9: GnRH). Exp 2 (n ¼ 55 cows) compared G-
7d and EB-7d protocols (similar to EB-9d, but D9 treatments were done on D7). Exp 3 (n ¼ 64 heifers)
compared EB-7d, G-7d, and P-5d protocols. For all experiments, daily ovarian ultrasonography was done
from D0 until 4d after implant withdrawal and blood samples were collected at D0 and first PGF. Follicle
dynamics were determined for each individual animal, analyzed within individual experiments, and
afterwards combined to determine overall effects of treatments. The protocol that began with GnRH, G-
7d, had greater ovulation rate after D0 with subsequently greater number of CL and circulating P4 at time
of PGF (52.8%, 1.0 ± 0.1 CL, 4.0 ± 0.4 ng/mL) than for EB protocols (12.1%, 0.4 ± 0.05 CL, 2.0 ± 0.2 ng/mL),
or P-5d (2.5%, 0.6 ± 0.09 CL, 2.6 ± 0.3 ng/mL). The G-7d and EB protocols had synchronized follicle wave
emergence in 92.1% of animals but with distinct patterns. For the G-7d group, wave emergence occurred
earlier in ovulating than non-ovulating animals (1.4 ± 0.2 d vs 2.5 ± 0.4 d). By comparison, most animals
in EB-7d or EB-9d (80.3%) displayed atresia of the dominant follicle, followed by wave emergence 2e3 d
after EB treatment. In contrast, P-5d protocol synchronized wave emergence in only 30.0% of cows.
Nevertheless, no differences among treatments were detected for ovulation at end of the protocol
(85.7%). In conclusion, the P-5d protocol did not synchronize follicle wave emergence but produced
similar final ovulation, whereas, GnRH and EB protocols had follicle dynamics synchronized by distinct
mechanisms that produced differences in CL number and P4 at the time of PGF treatment but similar
final ovulation. Based on ovarian function, each of these synchronization methods are promising for use
in FTAI, although fertility still needs to be evaluated. Keywords: Artificial insemination | Beef cattle | Estradiol | GnRH | Synchronization |

Early resynchronization of non-pregnant beef cows based in corpus luteum blood flow evaluation 21 days after Timed-AI
هماهنگی مجدد اولیه گاوهای گوشتی غیر باردار مبتنی بر ارزیابی جریان خون جسم زرد 21 روز پس از زمانبندی هوش مصنوعی -2020 The study aimed to verify whether a hormone protocol started at Day 13 (D13) after Timed Artificial
Insemination (TAI) influences the conception rate. Nelore cows (primiparous and multiparous) from two
commercial beef farms (n ¼ 1,431) were first TAI (D0). Timed AI was performed in lots (TAI Lots) ranging
from 187 to 346 cows. On D13, regarding the TAI lot, cows were assigned for either receiving (Resynch
group, n ¼ 1,002) or not (Control group, a subset of approximately 30%, n ¼ 429) another hormone
protocol for resynchronization. The same hormone protocol was used for the first TAI and for the
resynchronization, except for 1 mg instead of 2 mg of estradiol benzoate (EB) at the begging of the
protocol. Eight days later (D21), the Resynch group was checked for corpus luteum blood flow by color
Doppler ultrasonography, and in those detected as non-pregnant, the protocol was completed and a 2nd
TAI was performed at D23. Pregnancy diagnosis was later (D30) performed by B-mode ultrasonography
in the control group and confirmed in the presumptive pregnant cows from the 1st TAI of the Resynch
group. The remaining cows were checked for pregnancy 30 days after the 2nd TAI (experimental Day 53).
The statistical model to explain conception rate considered the effects of Group (Control or Resynch),
Farm, Parity (primiparous or multiparous), Sire, Technician (who perform AI), TAI Lot and pertinent
interactions (Group*Parity, Group*Farm and Group*TAI Lot). The statistical analyses of the model were
performed using the Proc Glimmix (SAS virtual University Edition). The conception rate for the 1st TAI
was similar (P > 0.4) between Control (50.3%, 216/429) and Resynch group (52.6%, 527/1002). The
positive predictive diagnostic on D21 showed high relation with PD30 (90.7%, 527/581). In Resynch
group, non-pregnant cows (n ¼ 421, 1002 minus 581) were re-inseminated. The conception rate of the
2nd TAI (42.8%, 180/421) was affected (P < 0.002) by side effects of the Farm (48.5 vs. 33.1%) and Parity
(51.2 vs. 40.3%, for multiparous vs. primiparous, p < 0.001). Nevertheless, after the 2 TAIs of the Resynch
group, the cumulative conception rate was 70.5% (707/1002). In conclusion, the early resynchronization
of cows with a low (1 mg) EB dose and progesterone device at D13 after TAI can be used as a strategy to
reduce conception interval in beef cattle, and thus to increase the number of pregnant cows from artificial
insemination after the breeding season. Keywords: Color Doppler | Pregnancy diagnosis | Re-insemination |

Progesterone-based timed AI protocols for Bos indicus cattle III: Comparison of protocol lengths
پروتکل های هوش مصنوعی بهنگام پروژسترون برای Bos indicus III: مقایسه طول پروتکل-2020 This study aimed to validate a 7 d progesterone (P4)-based fixed-time AI (FTAI) protocol for Bos indicus
cattle by comparing to 8 and 9 d-type protocols. The first study compared 7 vs. 8 d protocols in Nelore
heifers (Exp. 1.1; n ¼ 742) and cows (Exp. 1.2; n ¼ 2488), and the second study compared 7 vs. 9
d protocols in cows (Exp. 2; n ¼ 1343). On experimental Day 10 and Day 11 the 8 and 9 d groups
received an intravaginal P4 implant, 2.0 mg estradiol benzoate (EB) and 0.5 mg cloprostenol sodium
(PGF). On Day 9 the 7 d group received the same treatments (P4, EB, and PGF). Then, on Day 2 all
groups had the P4 implants removed, and PGF, 0.6 mg estradiol cypionate, and 300 IU equine chorionic
gonadotropin (eCG) was administered. Fixed-time AI was performed 48 h later (Day 0) and 8.4 mg
buserelin acetate (GnRH) was administered to 7d-G, 8d-G and 9d-G groups, whereas 7d-0, 8d-0 and 9d-
0 groups did not receive GnRH at AI. Estrus was detected using tail-chalk between Day 2 and Day 0.
Pregnancy per AI (P/AI) was evaluated by ultrasound 30 d after AI. Effects were considered significant
when P 0.05, whereas a tendency was designated when P 0.10 and P > 0.05. In heifers (Exp. 1.1),
incidence of estrus was similar regardless of protocol length (7 or 8 d). There was no independent
treatment effect on P/AI or interaction between protocol length and GnRH at AI for P/AI (7d-0: 46.9, 7d-
G: 51.4, 8d-0: 47.7, and 8d-G: 43.6%). Heifers in estrus had greater P/AI, and GnRH had no additional
effect. More cows (Exp. 1.2) from the 8 d protocol were in estrus than cows submitted to the 7 d protocol.
Additionally, despite no interaction between protocol length and GnRH on P/AI (7d-0: 55.9, 7d-G: 60.9,
8d-0: 56.2, and 8d-G: 60.8%), GnRH at AI increased P/AI. There was no interaction between estrus and
GnRH, but cows displaying estrus had greater P/AI. Cows not expressing estrus tended (P ¼ 0.06) to have
greater P/AI when receiving GnRH. In Exp. 2, more 9 d cows were in estrus than 7 d cows. Protocol length
did not affect P/AI but tended (P ¼ 0.08) to interact with GnRH (7d-G had greater P/AI [57.9%] than 7d-
0 [47.6%], but 9d-0 [54.6%] and 9d-G [55.4%] were not different from other groups). Moreover, GnRH
increased P/AI only for the 7 d protocol. No interaction between estrus and GnRH was detected but estrus
improved P/AI, and GnRH tended (P ¼ 0.09) to improve P/AI of cows in estrus. In conclusion, despite
longer protocols being more conducive to expression of estrus, there were no detectable effects of
protocol length on P/AI. In addition, GnRH at FTAI may improve fertility in cows, particularly when cows
are treated with shorter protocols. Keywords: Beef cattle | Estrus | Fertility | Nelore | Synchronization |

Prostaglandin F2a influences pre-ovulatory follicle characteristics and pregnancy per AI in anovular dairy cows
پروستاگلاندین F2a بر خصوصیات فولیکول قبل از تخمک گذاری و بارداری در هوش مصنوعی در گاوهای شیری بی قاعده تأثیر می گذارد-2020 Objectives were to determine the effects of a dose of PGF2a administered 2 days before timed artificial
insemination (AI) on LH pulsatility, characteristics of the pre-ovulatory follicle, and pregnancy per
artificial insemination (P/AI) in anovular dairy cows, particularly in cows not subjected to hyperthermia.
In experiment 1, 2,011 lactating Holstein cows had ovaries scanned by ultrasound to determine corpus
luteum (CL) presence and only those without a CL in two consecutive exams were enrolled (n ¼ 437).
Cows had the estrous cycle synchronized with an estradiol-progesterone based protocol starting on
experiment Day 11 and timed AI on Day 0. Cows were assigned randomly to receive a single dose of
25 mg of PGF2a as dinoprost on Day 4 (1PGF, n ¼ 222) or two doses of 25 mg each of PGF2a, one on
Day 4 and one on Day 2 (2PGF, n ¼ 215). Rectal temperatures were evaluated on the day of AI and 7
days later and cows were classified as being normothermic (<39.1 C) or hyperthermic (39.1 C).
Ovulatory responses and P/AI were determined. In experiment 2, cows with regressed CL were exposed
to low concentrations of progesterone and then randomly assigned to the same estrous synchronization
protocol and treatments, 1PGF (n ¼ 28) and 2PGF (n ¼ 28). Blood was sampled and analyzed for concentrations
of progesterone, and for concentrations of LH and 13,14-dihydro-15-keto-PGF2a metabolite
(PGFM) every 15 min starting 1 h before to 6 h after treatments and then every 2 h from 12 to 59 h after
treatments. The pre-ovulatory follicle was aspirated 44 h after treatments and concentrations of estradiol
quantified. In experiment 1, treatment of anovular cows with a second dose of PGF2a increased P/AI in
normothermic cows (19.8 [18/91] vs. 38.8% [31/80]), but not in hyperthermic cows. Synchronization was
not affected by treatment, but it was greater for normothermic than hyperthermic cows (87.1 [149/171]
vs. 77.8% [207/266]). When only synchronized cows were evaluated, the same responses were observed;
treatment with 2PGF increased P/AI compared with 1PGF in normothermic cows (23.1 [18/78] vs. 43.7%
[31/71]), but not in hyperthermic cows. In experiment 2, administration of 25 mg of dinoprost in 2PGF
resulted in concentrations of PGFM 26-fold greater than 1PGF in the first 6 h after treatment (48 vs.
1,242 pg/mL). Cows receiving 2PGF had smaller basal LH concentration (0.57 vs. 0.46 ng/mL) and less
frequent LH pulses (4.5 vs. 3.9 pulses/6 h), but duration of the LH surge was longer for 2PGF than 1PGF
(13.1 vs. 15.5 h). Treatment with 2PGF increased the diameter and volume of the pre-ovulatory follicle,
and concentration of estradiol (115 vs. 262 ng/mL) and total follicular estradiol content (124 vs. 505 ng)
compared with 1PGF. Collectively, these results suggest that PGF2a has a role in fertility of anovular cows
that is unrelated to its luteolytic effect. Keywords: Anovular | Follicle | Dairy cow | Prostaglandin |

Treatment with estradiol cypionate at progesterone withdrawal reduces handling without compromising the pregnancy rate to timed- AI in buffalo
درمان با استرادیول سیپیونات در ترک پروژسترون ، دست زدن بدون به خطر انداختن میزان حاملگی به موقع هوش مصنوعی در بوفالو را کاهش می دهد-2020 The aim of this study was to determine if treatment with estradiol cypionate (EC) at the time of P4
withdrawal induced ovulation in a synchronization/timed-AI (TAI) protocol in buffalo. In Experiment 1,
56 buffaloes received an intravaginal P4 device (1.0 g) plus estradiol benzoate (EB, 2.0 mg im) on Day
0 (D0). On Day 9, the P4 device was removed and buffaloes were given PGF2a (0.53 mg im sodium
cloprostenol) plus eCG (400 IU im). Buffaloes were then randomly allocated to one of two groups: Group
GEC (n ¼ 29), treated with EC (1.0 mg im) at P4 device removal; Group GEB (n ¼ 27), treated with EB
(1.0 mg im) 24 h after P4 device removal. Ovarian ultrasound was undertaken on: D0, to ascertain general
ovarian status; D9 to D11 (every 24 h), to measure diameter of the largest follicle (LF) and follicular
growth rate; D11 to D13 (every 12 h for 72 h), to determine the time of ovulation and ovulation rate.
Following P4 device removal, Groups GEC and GEB had a similar follicular growth rate (0.9 ± 0.1 and
1.1 ± 0.1 mm/day, respectively; P ¼ 0.15) and similar LF diameter on D11 (11.4 ± 0.6 and 12.5 ± 0.5 mm;
P ¼ 0.12). Groups GEC and GEB also had a similar diameter of the ovulatory follicle (13.0 ± 0.5 and
13.4 ± 0.6 mm; P ¼ 0.52), interval from P4 device removal to ovulation (68.2 ± 2.8 and 71.1 ± 1.4 h;
P ¼ 0.41) and ovulation rate (62.1% and 70.4%; P ¼ 0.44). In Experiment 2, 199 buffaloes were assigned to
the two treatments in Experiment 1 (GEC, n ¼ 100; GEB, n ¼ 99). All animals underwent TAI 56 h after P4
device removal and pregnancy diagnosis was preformed on D41. The pregnancy rate was similar for
Groups GEC and GEB (50.0 and 45.5%, respectively; P ¼ 0.45). The findings indicate that treatment with
EC at the time of P4 withdrawal induces ovulation and achieves the same pregnancy rate to TAI as
treatment with EB 24 h after P4 removal. The use of EC requires one less handling which is highly
important in facilitating practical adoption of TAI in assisted breeding and genetic improvement in
buffalo. Keywords: Buffalo | Estradiol cypionate | Ovulation synchronization | Pregnancy | Timed-AI |

Explosive, continuous and frustrated synchronization transition in spiking Hodgkin–Huxley neural networks: The role of topology and synaptic interaction
انتقال همزمان ، انفجاری ، مداوم و ناامید کننده در شبکه های عصبی هوچکین-هاکسلی اسپایک: نقش توپولوژی و تعامل سیناپسی-2020 Synchronization is an important collective phenomenon in interacting oscillatory agents. Many functional
features of the brain are related to synchronization of neurons. The type of synchronization
transition that may occur (explosive vs. continuous) has been the focus of intense attention in recent
years, mostly in the context of phase oscillator models for which collective behavior is independent of
the mean-value of natural frequency. However, synchronization properties of biologically-motivated
neural models depend on the firing frequencies. In this study we report a systematic study of gammaband
synchronization in spiking Hodgkin–Huxley neurons which interact via electrical or chemical
synapses. We use various network models in order to define the connectivity matrix. We find that
the underlying mechanisms and types of synchronization transitions in gamma-band differs from
beta-band. In gamma-band, network regularity suppresses transition while randomness promotes a
continuous transition. Heterogeneity in the underlying topology does not lead to any change in the
order of transition, however, correlation between number of synapses and frequency of a neuron will
lead to explosive synchronization in heterogeneous networks with electrical synapses. Furthermore,
small-world networks modeling a fine balance between clustering and randomness (as in the cortex),
lead to explosive synchronization with electrical synapses, but a smooth transition in the case of
chemical synapses. We also find that hierarchical modular networks, such as the connectome, lead
to frustrated transitions. We explain our results based on various properties of the network, paying
particular attention to the competition between clustering and long-range synapses. Keywords: Synchronization | Hodgkin–Huxley neuron | Phase transition | Electrical and chemical synapses | Complex networks |

What electrophysiology tells us about Alzheimer’s disease: a window into the synchronization and connectivity of brain neurons
آنچه الکتروفیزیولوژی در مورد بیماری آلزایمر به ما می گوید: پنجره ای برای هماهنگ سازی و اتصال نورون های مغز-2020 Electrophysiology provides a real-time readout of neural functions and network capability in different
brain states, on temporal (fractions of milliseconds) and spatial (micro, meso, and macro) scales unmet
by other methodologies. However, current international guidelines do not endorse the use of electroencephalographic
(EEG)/magnetoencephalographic (MEG) biomarkers in clinical trials performed in
patients with Alzheimer’s disease (AD), despite a surge in recent validated evidence. This position paper
of the ISTAART Electrophysiology Professional Interest Area endorses consolidated and translational
electrophysiological techniques applied to both experimental animal models of AD and patients, to probe
the effects of AD neuropathology (i.e., brain amyloidosis, tauopathy, and neurodegeneration) on
neurophysiological mechanisms underpinning neural excitation/inhibition and neurotransmission as
well as brain network dynamics, synchronization, and functional connectivity, reflecting thalamocortical
and corticocortical residual capacity. Converging evidence shows relationships between abnormalities in
EEG/MEG markers and cognitive deficits in groups of AD patients at different disease stages. The supporting
evidence for the application of electrophysiology in AD clinical research as well as drug discovery
pathways warrants an international initiative to include the use of EEG/MEG biomarkers in the main
multicentric projects planned in AD patients, to produce conclusive findings challenging the present
regulatory requirements and guidelines for AD studies.

Optimal energy management for a grid connected PV-battery system
مدیریت بهینه انرژی برای سیستم باتری PV متصل به شبکه-2020 The increase demand for electricity and the non-renewable nature of fossil energy makes the move towards renewable
energies required. However, the common problem of renewable sources, which is the intermittence, is overcome by the
hybridization of complementary sources. Thus, whenever the load demand is not fully covered by the primary source, the
second one will absolutely support it.
Furthermore, the production, the interaction with the grid and the storage system must be managed by the grid-connected
hybrid renewable energy system, which is the main objective of this paper. Indeed, we propose a new system of a grid-connected
PV-battery, which can manage its energy flows via an optimal management algorithm. The DC bus source connection topology
in our proposed hybrid architecture tackles the synchronization issues between sources when the load is powered. We consider
in this work that choosing a battery discharge and charge limiting power provides an extension of the battery life. On the other
hand, we simulated the dynamic behavior of the architecture’s various components according to their mathematical modeling.
Following this, an energy management algorithm was proposed, and simulated using MATLAB/SIMULINK to serve the load.
The results have shown that the load was served in all cases, taking into account the electrical behavior of the inhabitants as
well as the weather changes on a typical day. Indeed, the load was served either by instant solar production between sunrise
and sunset, or the recovery from sunset to 10pm, which could be a stored or injected energy without exceeding the 1000W
